                               PROSPECTUS SUMMARY

    THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE MORE
DETAILED INFORMATION AND FINANCIAL STATEMENTS APPEARING ELSEWHERE IN THIS
PROSPECTUS.

                                  OUR BUSINESS

    We are the leading diversified, facilities-based telecommunications provider
in Alaska, offering local telephone, wireless, long distance, data and Internet
services to business and residential customers throughout the state. We are the
only telecommunications provider in Alaska using its own network facilities to
provide end-to-end communications services to its customers.

    LOCAL TELEPHONE.  With over 320,000 access lines, representing 75% of the
access lines in Alaska, we are the largest local exchange carrier in Alaska and
the 15th largest in the U.S. We provide service to all of the state's major
population centers, including Anchorage, Juneau and Fairbanks.

    WIRELESS.  We are the largest and only statewide provider of wireless
services in Alaska, currently serving over 70,000 subscribers. Our wireless
network covers over 460,000 residents, including all major population centers
and highway corridors. We are in the process of upgrading our network to be
fully digital in all of our service areas by year-end 1999.

    LONG DISTANCE.  We provide long distance and other interexchange services to
approximately 26,000 customers primarily in Anchorage and intend to market these
services statewide beginning in the first quarter of 2000. We recently migrated
long distance traffic from leased circuits onto our own network infrastructure,
which we believe will result in significant cost savings over time.

    DATA AND INTERNET.  We are the third largest provider of Internet access
services in Alaska, with approximately 16,000 customers. We also own 28.5% of
the second largest Internet services provider in Alaska, with approximately
28,000 customers. We currently offer dedicated and dial-up Internet access to
our customers and intend to offer digital subscriber line, or DSL, services by
year-end 1999.

    In addition, we recently acquired a majority interest in a provider of
wireless cable television services in our Anchorage and Fairbanks service areas
and expect to expand our offering of wireless cable services using digital
compression technology.


    Our telecommunications network includes over 485 miles of fiber optic cable,
176 switching facilities and a statewide cellular network. In addition, we
recently purchased fiber capacity for high speed links within Alaska and for
termination of traffic in the lower 48 states. We plan to continue enhancing our
network to meet customer demand for increased bandwidth and advanced services.

    For the year ended December 31, 1998, on a pro forma basis, we would have
had combined revenues of $281.6 million, operating income of $40.6 million,
Adjusted EBITDA, as defined under "Summary Unaudited Pro Forma Combined
Financial and Operating Data", of $106.1 million and a net loss of
$17.3 million.


    We were formed in 1998 by Fox Paine & Company, LLC, members of the former
senior management team of Pacific Telecom, Inc., and other experienced
telecommunications industry executives. In May 1999, we acquired the Alaska
telecommunications properties of Century Telephone Enterprises, Inc. and
substantially all of the assets and liabilities of the Anchorage Telephone
Utility, or ATU. Century's Alaska properties were the incumbent provider of
local telephone services in Juneau, Fairbanks and more than 70 rural communities
in Alaska and provided Internet services to customers statewide. ATU was the
largest local exchange carrier in Alaska and provided local telephone and long
distance services primarily in Anchorage and cellular services statewide. On
October 28,1999, we changed our name from ALEC Holdings, Inc. to Alaska
Communications Systems Group, Inc.

                            OUR BUSINESS OPPORTUNITY

    Alaska is characterized by its large geographic size, widely dispersed
population and large distance between urban areas. Over 60% of the state's
population resides in its three largest cities, Anchorage, Juneau and Fairbanks.
Alaska lacks an effective ground transportation infrastructure, and many of the
state's communities are accessible only by air or water. As a result, Alaskans
are particularly dependent on telecommunications services to access resources
and information unavailable in their communities. We estimate that Alaskan
telecommunications businesses generated aggregate revenues of $1 billion in
1998.

    Alaska's income and demographic characteristics provide opportunities for
significant growth of telecommunications services. Alaska has the highest median
household income in the U.S. In addition, Alaskans pay no state personal income
taxes and receive an annual per capita payment from the Alaska Permanent Fund.
The population in Alaska has been growing at a compound annual rate of 1.3% over
the last ten years, compared to 1.0% for the U.S. as a whole. The U.S. Census
Bureau projects that Alaska's population will grow at a compound annual rate of
1.9%, as compared to 0.8% for the U.S. as a whole, through 2005.

    We believe that the outlook for growth in our businesses is favorable due to
the fundamental demand for telecommunications, including:

    - continued demand for core telephone services and enhanced service
      offerings, such as voice mail and call waiting,

    - access line growth due to population growth and the demand for multiple
      lines,

    - increasing demand for wireless services and

    - DSL and Internet access growth due to higher business and consumer
      bandwidth needs for data and Internet services.

                             OUR BUSINESS STRATEGY

    As part of our business strategy, we intend to:

    LEVERAGE OUR NETWORK AND CUSTOMER BASE.  Our competitive position as the
leading diversified, facilities-based telecommunications provider in Alaska
affords us a valuable opportunity to capitalize on the growing demand for
communications services. In particular, we intend to:

        PROVIDE ONE-STOP COMMUNICATIONS SERVICES.  We intend to offer a complete
    suite of telecommunications and data services, including:

      - local telephone,

      - wireless,

      - long distance and

      - data and Internet services.

        INCREASE PENETRATION OF ENHANCED SERVICES.  We seek to achieve a higher
    penetration of high-margin enhanced services. Offered services include:

      - call waiting,

      - caller ID,

      - call forwarding and

      - voice mail.

        OFFER COMPLEMENTARY COMMUNICATIONS AND MEDIA SERVICES.  We currently
    offer ISDN and other high-speed data services and intend to expand our
    service offerings to include:

      - DSL services by year-end 1999,

      - virtual private networks and

      - statewide Centrex services, such as four-digit dialing.

    PROVIDE SUPERIOR CUSTOMER SERVICE. We are committed to building strong
customer relationships by providing high-quality customer care. We intend to
increase customer loyalty and retention by:

    - improving call response times,

    - providing one-call customer solutions and

    - offering online customer account management services.

    BUILD THE LEADING COMMUNICATIONS BRAND IN ALASKA.  Through future promotion
of all of our service offerings under the "Alaska Communications Systems" brand
name, we intend to take advantage of our statewide presence and centralized
marketing to:

    - build superior brand awareness,

    - drive greater penetration of our products and services and

    - create higher demand for premium-priced branded services.

    REALIZE OPERATING EFFICIENCIES.  We seek to realize significant operating
efficiencies by:

    - eliminating duplicative overhead from our recent acquisitions,

    - investing in new cost-effective information technology and

    - creating an integrated, low cost network.

    PURSUE SELECTED STRATEGIC ACQUISITIONS. We intend to pursue selected
investments in or acquisitions of:

    - local exchange carriers in Alaska and

    - entities whose businesses complement our existing product and service
      offerings.

Use of Proceeds..............................  We estimate that we will receive net proceeds
                                               from the offering of approximately $129.0
                                               million. We intend to use $26.5 million of
                                               the net proceeds to repay debt, including:

                                               -  $10.5 million to redeem a portion of our
                                                  senior discount debentures, including a
                                                  $1.2 million redemption premium, and

                                               -  $16.0 million of borrowings under our
                                                  revolving credit facility.

                                               We intend to use the balance of the net
                                               proceeds for capital expenditures, strategic
                                               investments and acquisitions, including
                                               acquisitions of access lines, and general
                                               corporate purposes. Depending on the timing
                                               of these expenditures, we may also use a
                                               portion of the proceeds to repay a portion of
                                               our outstanding term loans.

                                               This discussion of our use of proceeds
                                               assumes the effectiveness of an amendment to
                                               the credit agreement for our senior credit
                                               facility that we recently entered into with
                                               our senior lenders. If the amendment does not
                                               become effective, we will seek another
                                               amendment or continue to operate our business
                                               in a manner consistent with the credit
                                               agreement.

                                               The senior discount debentures, the senior
                                               credit facility and the amendment to the
                                               credit agreement are described under
                                               "Description of Indebtedness--The Senior
                                               Credit Facility" and "--The Alaska

1999 Stock Incentive Plan and (2) approximately 828,000 shares of common stock
that we expect to issue upon the cashless exercise of 828,261 outstanding
warrants in connection with the offering. We also expect to have 2,650,000
shares of common stock reserved for issuance under the stock incentive,
non-employee director compensation and stock purchase plans we intend to adopt
in connection with the offering. These plans are described under
"Management--Compensation of Directors--Alaska Communications Systems Group,
Inc. 1999 Non-Employee Director Stock Compensation Plan", "--ALEC Holdings, Inc.
1999 Stock Incentive Plan", "--Alaska Communications Systems Group, Inc. 1999
Stock Incentive Plan" and "--Alaska Communications Systems Group, Inc. 1999
Employee Stock Purchase Plan". Also, the calculation of the shares outstanding
after the offering assumes that the underwriters will not exercise the option
granted by us to purchase up to 1,500,000 additional shares of common stock in
the offering, as described under "Underwriting".

       SUMMARY UNAUDITED PRO FORMA COMBINED FINANCIAL AND OPERATING DATA


    The following summary unaudited pro forma combined financial and operating
data are based on the financial statements of Century's Alaska properties and
ATU, as adjusted to illustrate the estimated effects of:

    - the acquisition in May 1999 of Century's Alaska properties,

    - the acquisition in May 1999 of ATU,

    - the purchase in June 1999 of fiber capacity for $19.5 million,

    - the financings entered into to complete these acquisitions and

    - the offering and the application of the net proceeds of the offering, as
      described under "Use of Proceeds",


as if they had occurred at the beginning of the periods presented with respect
to the operating, financial and other data and on September 30, 1999 with
respect to the balance sheet data.


    The summary unaudited pro forma combined financial and operating data do not
purport to be indicative of what our financial position or results of operations
would actually have been had these transactions been completed on the dates
indicated, or to project our results of operations for any future period, and
should be read in conjunction with "Unaudited Pro Forma Combined Financial
Statements", "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and the financial statements and the related notes which
are included elsewhere in this prospectus.

    You should also keep the following points in mind as you read the table.


    - "Other income (expense)" includes the equity in losses of minority
      investments, which were $2,945,000 for the year ended December 31, 1998
      and $1,452,000 for the nine months ended September 30, 1999.


    - Net cash data includes information from ATU's financial statements
      prepared according to governmental accounting standards. The differences
      between governmental accounting standards and the standards promulgated by
      the Financial Accounting Standards Board, and their impact on ATU's
      financial statements, are discussed in Note 1 to the financial statements
      of Municipality of Anchorage Telephone Utility Fund which are included
      elsewhere in this prospectus.

    - "EBITDA" is net income before interest expense, income taxes, depreciation
      and amortization. EBITDA is not intended to represent cash flow from
      operations as defined under generally accepted accounting principles, and
      should not be considered as an alternative to net income as an indicator
      of our operating performance or cash flows. EBITDA is included in this
      prospectus because management believes it is a useful financial
      performance measure for comparing companies in the telecommunications
      industry in terms of operating performance and ability to satisfy debt
      service, capital expenditure and working capital requirements.

    - "Adjusted EBITDA" for the year ended December 31, 1998 is EBITDA increased
      by:

        - the net effect of the elimination of one-time duplicative
          administrative charges resulting from Century's acquisition of Pacific
          Telecom, and the related loss of revenues, in the amount of
          $1,399,000,

        - unrealized access revenues in the amount of $417,000 that were not
          recovered in 1998 but are being recovered in 1999,

        - the net effect of reduced operating expenses, primarily leased circuit
          expenses, partially offset by higher maintenance expenses, that would
          have been experienced had the purchase of fiber capacity occurred

                                       8
<PAGE>
          on January 1, 1998, in the amount of $2,047,000 and

        - the equity in losses of minority investments, which were $2,945,000.


    - "Adjusted EBITDA" for the nine months ended September 30, 1999 is EBITDA:



        - increased by (1) $1,535,000 net cost savings related to the purchase
          of fiber capacity, (2) $7,695,000 of non-recurring expense and
          transaction costs associated with our acquisitions of Century's Alaska
          properties and ATU and (3) the equity in losses of minority
          investments, which were $1,452,000, and


        - decreased by $1,570,000 of revenues related to prior periods.


    - Operating cash flows would have been increased by $2,047,000 for the year
      ended December 31, 1998 and by $1,535,000 for the nine months ended
      September 30, 1999, had the purchase of fiber capacity occurred on
      January 1, 1998.

    - "Pro forma cash interest expense" is defined as interest expense exclusive
      of amortization of deferred financing costs.

    - "Access lines in service" includes all revenue producing lines connected
      to retail or wholesale customers.

    SUMMARY HISTORICAL COMBINED FINANCIAL DATA--CENTURY'S ALASKA PROPERTIES

    The following table sets forth summary historical combined financial data of
Century's Alaska properties. You should keep the following points in mind as you
read the table.

    - We derived the summary historical combined financial data included in the
      table from the combined financial statements and the related notes of
      Century's Alaska properties, some of which are included elsewhere in this
      prospectus.

    - Century acquired its Alaska properties on December 1, 1997 as part of its
      acquisition of Pacific Telecom. This acquisition was accounted for as a
      purchase, resulting in a pushdown of $208.0 million of goodwill to
      Century's Alaska properties.

    - The data for the year ended December 31, 1997 represent the results of
      Century's Alaska properties for the first 11 months of the year, as owned
      by Pacific Telecom, and the last month of the year, as owned by Century.
    - The data include the results of the telephone operation of the City of
      Fairbanks from October 6, 1997, the date of its acquisition. This
      acquisition was accounted for as a purchase.

    - On December 31, 1997, the cellular operations of Fairbanks were sold to
      ATU.
    The summary historical combined financial data should be read in conjunction
with "Selected Historical Combined Financial Data--Century's Alaska Properties",
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and the combined financial statements and the related notes of
Century's Alaska properties which are included elsewhere in this prospectus.

                     SUMMARY HISTORICAL FINANCIAL DATA--ATU

    The following table sets forth summary historical financial data of ATU. You
should keep the following points in mind as you read the table.

    - We derived the summary historical combined financial data included in the
      table from the financial statements and related notes of ATU, some of
      which are included elsewhere in this prospectus.

    - ATU was a public utility of the Municipality of Anchorage and was exempt

    - Net cash data includes information from ATU's financial statements
      prepared in accordance with governmental accounting standards. The
      differences between governmental accounting standards and the standards
      promulgated by the Financial Accounting Standards Board, and their impact
      on ATU's financial statements, are discussed in Note 1 to the financial
      statements of Municipality of Anchorage Telephone Utility Fund which are
      included elsewhere in this prospectus.

    The summary historical financial data below should be read in conjunction

                                  RISK FACTORS

    AN INVESTMENT IN OUR COMMON STOCK INVOLVES A HIGH DEGREE OF RISK. YOU SHOULD
CAREFULLY CONSIDER THE FOLLOWING FACTORS, TOGETHER WITH THE OTHER INFORMATION IN
THIS PROSPECTUS, BEFORE DECIDING TO PURCHASE SHARES OF OUR COMMON STOCK.

THE TELECOMMUNICATIONS INDUSTRY IS EXTREMELY COMPETITIVE, AND WE MAY HAVE
  DIFFICULTY COMPETING EFFECTIVELY


    As the incumbent local exchange carrier, we face competition mainly from
resellers, local providers who lease unbundled network elements from us and, to
a lesser degree, from facilities-based providers of local telephone services. In
September 1997, GCI, Inc. and AT&T Alascom, Inc., the two largest long distance
carriers in Alaska, began providing competitive local telephone services in
Anchorage: GCI principally through unbundled network element interconnection
with ATU's facilities, and AT&T Alascom through the resale of ATU's services. As
a result, ATU lost approximately 19% of its retail access lines in Anchorage to
these competitors during the first ten months of competition ended June 1998,
and these competitors currently have approximately 23% of the retail access
lines in Anchorage. We cannot be sure that we will not continue to lose
customers to GCI and AT&T Alascom or to other new providers of local telephone
service.



    As "rural telephone companies" under the Telecommunications Act, our rural
local exchange carriers have historically been exempt from the obligation to
lease their facilities or resell their services on a wholesale discounted basis
to competitive local exchange carriers seeking interconnection. However, on June
30, 1999, the Alaska Public Utilities Commission, commonly know as the APUC,
ordered these exemptions terminated. We sought reconsideration of that order
from the new Regulatory Commission of Alaska, or RCA, which replaced the APUC on
July 1, 1999. On October 11, 1999, the RCA sustained the APUC order terminating
our rural exemptions. As a result, we may be subject to interconnection duties,
such as the provisioning of unbundled network elements and of wholesale
discounted resale services to competitors in some or all of our rural service
areas. Interconnection duties are governed by telecommunications rules and
regulations related to the unbundled network elements that must be provided.
These rules and regulations were recently revised and remain subject to ongoing
modifications. The termination of the rural exemptions is more fully described
under "--Revocation of the substantial protections from competition granted to
our rural local exchange carriers under the Telecommunications Act of 1996 could
result in increased competition". In addition, while cellular wireless services
have historically complemented traditional local exchange services, we
anticipate that existing and emerging wireless technologies may increasingly
compete with local exchange services in some or all of our service areas.


    With respect to our wireless services, we currently compete with at least
one other cellular provider in each of our wireless service areas. In addition,
we have one PCS competitor in Anchorage. Some of our competitors are formidable,
with financial and technical resources greater than ours.

    In long distance, we currently have less than 2.5% of total long distance
revenues in Alaska and face competition from AT&T Alascom and GCI, the two major
long distance providers in Alaska.

    In the highly competitive Internet access services business, we expect that
competition will intensify in the future due to the absence of significant
barriers to entry. We currently compete with a number of established online
services companies, interexchange carriers and cable companies.


    Aggressive competition in all of the markets in which we operate could:



    - reduce our customer base,


                                       12
<PAGE>

    - require us to lower rates and other prices in order to compete,



    - increase marketing expenditures and use of discounting and promotional
      campaigns that would adversely affect our margins or,



    - otherwise have an adverse effect on our results of operations.


FAILURE TO INTEGRATE OUR RECENT ACQUISITIONS SUCCESSFULLY MAY PREVENT US FROM
  REALIZING PLANNED OPERATING GAINS AND EFFICIENCIES AND OTHERWISE FROM
  IMPLEMENTING OUR BUSINESS STRATEGY

    Our ability to operate successfully is dependent on our ability to integrate
the operations of Century's Alaska properties and ATU and manage the growth
expected to result from the combination of those businesses. Our success will
depend on our ability to, among other things:

    - retain and assimilate qualified managerial, professional and technical
      personnel from the acquired businesses,

    - centralize general and administrative support services and information
      technology platforms, and coordinate and integrate operational, financial
      and management processes, systems and controls, including the development
      of effective systems relating to ordering, provisioning and billing for
      telecommunication services,

    - successfully market all of our service and product offerings under a
      unified brand name, while raising brand awareness among our customers,

    - adopt and maintain uniform standards, control procedures and policies,

    - manage growth in our service and product offerings, while avoiding
      disruption of our existing business and

    - preserve good relationships with our suppliers, employees and customers.

    The expansion of our operations also will depend on our ability to, among
other things, assess markets, forecast regulatory trends, identify, finance and
complete suitable acquisitions and continue to expand and upgrade our network
backbone, all in a timely manner, at reasonable cost and on satisfactory terms
and conditions.

    Failure to successfully integrate our recent acquisitions or any businesses
we may acquire in the future could adversely impact our business strategy and
materially adversely effect our results of operations.

WE HAVE A SHORT OPERATING HISTORY WITH RESPECT TO OUR CURRENT BUSINESSES

    Prior to May 1999, substantially all of our current businesses were
conducted as part of Century or the Municipality of Anchorage and their
affiliates. After our acquisitions of Century's Alaska properties and ATU in May
1999, we engaged in business as an independent entity for the first time and
have since made significant changes, including personnel and organizational
changes.

THE ESTABLISHMENT OF A NEW REGULATORY AGENCY IN ALASKA MAKES THE DIRECTION OF
  INTRASTATE REGULATORY POLICY LESS CLEAR

    Effective on July 1, 1999, the APUC was extinguished by legislative action
and a new Regulatory Commission of Alaska, or RCA, was established. The statutes
and regulations of the state applicable to our businesses remained largely
intact and are now administered by the RCA. None of the former APUC
commissioners was appointed to the RCA, and only one of the new RCA
commissioners has prior APUC experience. Given the large number of proceedings
currently before

                                       13
<PAGE>
the RCA, including those addressing various aspects of local exchange
competition, access charges and universal service, the creation of a new
commission increases regulatory uncertainty regarding the timing and direction
of state regulatory policies.


REVOCATION OF THE SUBSTANTIAL PROTECTIONS FROM COMPETITION GRANTED TO OUR RURAL
  LOCAL EXCHANGE CARRIERS UNDER THE TELECOMMUNICATIONS ACT OF 1996 COULD RESULT
  IN INCREASED COMPETITION



    On June 30, 1999, the APUC issued an order revoking the regulatory
exemptions that our rural local exchange carriers then held. These exemptions
permitted our local exchange carriers in rural areas to deny interconnection
elements and wholesale discounted resale services to competitors. In July 1999,
we sought reconsideration from the RCA. On October 11, 1999, the RCA issued an
order sustaining the APUC decision. The RCA expressed a preference for
establishing terms and conditions for interconnection through the process of
negotiations between carriers and, in separate proceedings, indicated that it
does not intend at this time to establish interconnection rates and terms
through tariff proceedings.



    We are negotiating with potential competitors the terms and conditions of
interconnection in our rural service areas. Under the RCA's order, either party
may request arbitration of any unresolved interconnection issue at any time
after December 10, 1999. Under the Telecommunications Act of 1996, all
arbitration issues must be resolved within nine months of the original request
for interconnection. If we are unable to charge rates which fairly compensate us
for providing unbundled network elements and/or wholesale discounted resale
services, our financial and operating results could be adversely affected.



A REDUCTION OF THE RATES WE CHARGE OUR CUSTOMERS BY THE RCA OR THE FCC WOULD
  REDUCE OUR REVENUES AND EARNINGS


    The rates we charge our local telephone customers are based, in part, on a
rate of return authorized by the RCA on capital invested in our local exchange
carriers' networks. These authorized rates are subject to review and change by
the RCA at any time. If the RCA orders us to reduce our rates, both our revenues
and our earnings will be reduced.

    The APUC in the past indicated that one of our exchange carriers was earning
in excess of its historical authorized rate of return. Neither the RCA nor the
former APUC has initiated a proceeding to review or change the authorized rate
of return. As a condition to granting its approval of our recent acquisitions of
Century's Alaska properties and ATU, however, the APUC required that we file, by
June 30, 2001, revenue requirement, cost-of-service and rate design studies that
show our earnings levels for the year ended December 31, 2000. Based on
historical practice, the APUC did not generally initiate rate proceedings unless
a company, as a whole, was earning in excess of the average of its authorized
rates of return. We cannot assure you, however, that the RCA will not change
this practice, that our earnings levels, as disclosed in our studies, will not
exceed our authorized rates of return, or that the RCA will not initiate a rate
proceeding that results in the RCA ordering us to reduce our rates.


    In October 1998 the FCC initiated proceedings, but has not yet reached any
decision, regarding the appropriate rate of return to be applied for federal
rate-making purposes to companies like us that are not subject to price cap
regulation.


REVENUES FROM ACCESS CHARGES MAY BE REDUCED OR LOST

    We received 35.0% of our 1998 pro forma combined revenues from access
charges paid by interstate and intrastate interexchange carriers for originating
and terminating calls in their service areas. The amount of revenue that we
receive from access charges is calculated in accordance

                                       14
<PAGE>
with requirements set by the FCC and the RCA. Any change in these requirements
may reduce our revenues and earnings.

A REDUCTION IN THE UNIVERSAL SERVICE SUPPORT CURRENTLY RECEIVED BY SOME OF OUR
  SUBSIDIARIES WOULD REDUCE OUR REVENUES AND EARNINGS


    We received 4.8% of our 1998 pro forma combined revenues from the federal
Universal Service Fund, which was established under the direction of the FCC to
compensate carriers for the high cost of providing universal telecommunications
services in rural areas. We also receive payments from the Alaska Universal
Service Fund which, according to calculations made by the staff of the fund,
total approximately $1.5 million each year. If the subsidies received from these
funds were materially reduced or discontinued, some of our rural local exchange
carriers might not be able to operate profitably. The RCA is also considering
revisions to the Alaska Universal Service Fund which, if adopted as proposed by
the RCA, would diminish the amount of support that some of our rural local
exchange carriers would receive from the Alaska Universal Service Fund.



    Various reform proceedings are underway at the FCC to change the method of
calculating the amount of subsidies paid under the federal fund, and future
reforms are expected to replace the current historical cost system with a system
based on forward-looking economic costs. Reform proceedings are also underway in
Alaska to review carriers' support from the state fund, and proposals have been
made to require carriers to use payments received from the fund to provide
public interest pay telephones. In addition, the existence of the state fund has
been challenged in court. Any of these reforms, proposals and challenges may
result in a reduction or discontinuation of the subsidies available to our rural
operating companies.


WE MAY NOT BE ABLE TO OFFER LONG DISTANCE SERVICES ON A PROFITABLE BASIS

    Our long distance operations have historically been modest in relation to
the long distance businesses of our competitors and have generated operating
losses of $3.7 million in 1998 and $3.2 million in 1997. We intend to expand our
long distance operations substantially and change the way in which we offer
those services by packaging them with complementary services. There is no
assurance that our operating losses from long distance services will not
increase in the future, even after taking account of revenue from complementary
services.

    We have historically offered long distance services only in the Anchorage
area, and those services were provided on a "reseller" basis as we relied on
other carriers to provide the service. We recently acquired ownership of long
distance fiber optic transmission capacity connecting Juneau, Fairbanks and
Seattle with Anchorage and, where possible, we have transferred our long
distance traffic to our own network. We have also committed to purchase
additional fiber optic capacity in 2001. We plan to expand significantly our
marketing of long distance services by packaging them with complementary
telecommunications services, including statewide Centrex, Internet access and
high speed data services. Our existing long distance competitors can be expected
to respond to our initiatives and some of them have greater financial resources
than we have. We cannot predict that we will generate sufficient revenue from
these efforts to provide a satisfactory return on our recent $19.5 million
investment in fiber optic capacity or to fund $19.5 million in future
investments in additional fiber optic capacity that we are committed to make.

    We expect to continue to enter into resale agreements for a portion of our
long distance services. In connection with these agreements, we must estimate
future demand for our service. If we overestimate this demand, we may be
obligated to pay for services we do not need, and if we underestimate this
demand, we may need to lease additional capacity on a short-term basis at
unfavorable prices, assuming additional capacity is available. If additional
capacity is not available, we will not be able to meet this demand.

                                       15
<PAGE>
WE DEPEND ON KEY MEMBERS OF OUR SENIOR MANAGEMENT TEAM


    Our success depends largely on the skills, experience and performance of key
members of our senior management team. If we were to lose one or more of these
key employees our ability to successfully implement our business plan and the
price of our common stock could be materially adversely affected. We do not
maintain any "key person" insurance on any of our personnel.


ANY FAILURE TO REACH AGREEMENT IN THE NEGOTIATIONS WITH THE UNION REPRESENTING
  OUR EMPLOYEES COULD HAVE AN ADVERSE EFFECT ON OUR OPERATIONS


    Approximately 67% of our employees are represented by unions. Century's
Alaska properties have a collective bargaining agreement with the International
Brotherhood of Electrical Workers, or IBEW, that expires in 2004. ATU also has a
contract with the IBEW that was scheduled to expire in August 1999. Management
believes that negotiations with the IBEW regarding the terms under which ATU's
represented employees would be transitioned to Century's Alaska properties'
collective bargaining agreement are substantially concluded. The negotiated
collective bargaining agreement is scheduled to be voted on by the IBEW
membership on November 2, 1999. A failure to reach agreement with the IBEW could
adversely affect our operations.


OUR SUBSTANTIAL DEBT MAY REDUCE OUR FLEXIBILITY AND IMPAIR OUR OPERATIONS


    We have a significant amount of debt. As of September 30, 1999, we had
outstanding $625.4 million of debt, excluding unused commitments--of which
$21.2 million was our senior debt and $595.0 million was senior and senior
subordinated debt of our subsidiary, Alaska Communications Systems Holdings--and
stockholders' equity of $127.7 million. In addition, Alaska Communications
Systems Holdings' senior credit facility provides that Alaska Communications
Systems Holdings may borrow up to an additional $59.0 million under a revolving
credit facility as of November 1, 1999. The senior credit facility and the
indentures governing our senior discount debentures and senior subordinated
notes limit our and our subsidiaries' ability to incur additional debt and
impose significant restrictions on our ability to:


    - pay cash dividends and make other restricted payments,

    - sell assets or stock,

    - enter into transactions with affiliates,

    - effect mergers or other business combinations and

    - engage in other lines of business.

    In addition, the senior credit facility restricts our ability to prepay
existing debt and the amount of capital expenditures we can make in each year,
and requires us to meet specified financial ratios and tests.

    Our debt could adversely affect our operations by:

    - impairing our ability to borrow additional money on favorable terms,

    - requiring us to use a substantial portion of our operating cash flow to
      service debt, which would reduce the funds available for operations,
      capital expenditures, acquisitions and other investments in our business,

    - placing us at a competitive disadvantage against competitors with lesser
      debt burdens and

    - making us more vulnerable to a worsening of conditions in the markets in
      which we operate or in the U.S. economy generally.

                                       16
<PAGE>
    Although we intend to repay a portion of our indebtedness with the proceeds
of the offering, we will continue to have a significant amount of debt. We also
expect to incur additional debt in the future for capital expenditures, possible
future investments and acquisitions and working capital.

BECAUSE WE AND OUR DIRECT SUBSIDIARY, ALASKA COMMUNICATIONS SYSTEMS HOLDINGS,
  ARE HOLDING COMPANIES, WE BOTH RELY ON DISTRIBUTIONS FROM OUR SUBSIDIARIES TO
  SATISFY OUR OBLIGATIONS. IF WE DO NOT RECEIVE THOSE DISTRIBUTIONS FROM OUR
  SUBSIDIARIES, WE MAY NOT BE ABLE TO SERVICE OUR SUBSTANTIAL DEBT

    We cannot assure you that we will be able to meet our debt obligations.
Because we are a holding company with no significant assets or independent
operations other than the equity of Alaska Communications Systems Holdings, if
we do not receive dividends or other distributions from Alaska Communications
Systems Holdings that are sufficient for us to satisfy our obligations under our
senior discount debentures, or if Alaska Communications Systems Holdings, which
is also a holding company, does not receive dividends or other distributions
from its subsidiaries that are sufficient to satisfy its obligations under its
senior credit facility and senior subordinated notes, then, unless we can
refinance those obligations, a default could occur and payment of those
obligations could be accelerated. While we expect sufficient dividends to be
available to meet our debt service obligations, dividends from our subsidiaries
could be unavailable if those subsidiaries are unable to produce sufficient
operating cash flow or if dividends or other payments to us are otherwise
restricted by the agreements to which our subsidiaries are parties or by law or
regulatory order. In the event of an insolvency, bankruptcy or similar
proceedings involving one of our or Alaska Communications Systems Holdings'
subsidiaries, creditors of that subsidiary would generally be entitled to
priority over us with respect to the assets of the subsidiary.

    The lenders under Alaska Communications Systems Holdings' senior credit
facility have a first priority lien on all of the capital stock of Alaska
Communications Systems Holdings we own as well as on the common stock of all of
its subsidiaries. This stock accounts for substantially all of our assets, and
the stock of its subsidiaries accounts for substantially all of Alaska
Communications Systems Holdings' assets. If Alaska Communications Systems
Holdings defaults under the senior credit facility or if we default on our
guarantee of the senior credit facility, the lenders under the senior credit
facility could foreclose upon the capital stock of Alaska Communications Systems
Holdings and its subsidiaries. A foreclosure sale of our Alaska Communications
Systems Holdings stock could force us to accept a depressed value for our Alaska
Communications Systems Holdings common stock, and a foreclosure sale of the
common stock of Alaska Communications Systems Holdings' subsidiaries could force
Alaska Communications Systems Holdings to accept a depressed value for its
subsidiaries' common stock.

WE MAY NOT HAVE SUFFICIENT FUNDS TO REPAY OR REDEEM OUR DEBT IF WE ARE REQUIRED
  TO DO SO

    At maturity or upon the occurrence of a "change of control", as defined in
the documentation governing our debt obligations, we cannot assure you that we
will have sufficient funds or would be able to arrange for additional financing
to repay our debt obligations under the senior credit facility, our senior
discount debentures or the senior subordinated notes. There is no sinking fund
with respect to our senior discount debentures or the senior subordinated notes,
and at maturity the entire outstanding principal amount of those securities will
become due and payable. In addition, if a "change of control" occurs, each
holder of the debentures or notes will have the right to require us to
repurchase all or a portion of the holder's notes or debentures. However:

    - the senior credit facility effectively prevents the repurchase of our
      senior discount debentures and the senior subordinated notes in the event
      of a change of control, unless all amounts outstanding under the senior
      credit facility are repaid in full;

                                       17
<PAGE>
    - our failure to repurchase our senior discount debentures and the senior
      subordinated notes would be a default under the indentures governing them,
      which would be a default under the senior credit facility; and

    - our failure to repay all amounts outstanding under the senior credit
      facility upon a default would be a default under the indentures governing
      our senior discount debentures and the senior subordinated notes.

    Because we will probably not have sufficient cash flow from operations to
repay our senior discount debentures and the senior subordinated notes upon a
change of control, we may need to borrow additional amounts or seek other
sources of financing to repay them. We cannot guarantee that such additional
financing will be available or available on favorable terms.

WE COULD EXPERIENCE SIGNIFICANT BUSINESS DISRUPTIONS IF WE FAIL TO IDENTIFY AND
  RESOLVE POTENTIAL YEAR 2000 PROBLEMS IN A TIMELY MANNER

    Many existing computer systems and microprocessors use only two digits to
identify a year in the date field, which assumes that the first two digits of
the year are always "19". As a result, beginning on January 1, 2000, computers
that are not year 2000 compliant may interpret the year as "1900" instead of
"2000". Systems that calculate, compare or sort data using the incorrect date
may malfunction.

    We are significantly dependent upon the proper functioning of our computer
systems, digital switches and electronic transmission equipment. A failure of
our systems to be year 2000 compliant would have a material adverse effect on
our business. For example, failure could seriously disrupt our switches and
network, potentially resulting in business interruptions or shutdown.


    We also believe that, if we or our important vendors or suppliers experience
year 2000 problems, the problems could materially disrupt our business processes
and relationships with our customers or could require the expenditure of
material financial and other resources. We have conducted a review of the
computer systems and related software, digital switches and electronic
transmission equipment that we acquired upon completion of our acquisitions of
Century's Alaska properties and ATU. We have identified a number of systems that
are not year 2000 compliant and have implemented a plan that we believe will
ensure that these systems, software and equipment store and process information
properly in the year 2000. The action items required by this plan have been
largely completed as of the date of this prospectus.


    We have also made efforts to verify the year 2000 readiness of our important
vendors and suppliers. Although we believe the processes we have initiated are
adequate to remedy year 2000 deficiencies, we cannot assure you that these
remedies will be timely or effectively implemented or that we will be immune to
year 2000 deficiencies suffered by third parties that may in some way affect our
business in a materially adverse manner. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations" for a more detailed
discussion of our year 2000 readiness.

YOU WILL NOT RECEIVE CASH DIVIDENDS ON YOUR INVESTMENT IN OUR COMMON STOCK

    We have never declared or paid any cash dividends on our common stock. We
intend to retain our earnings, if any, to finance the development and expansion
of our business, and, therefore, we do not anticipate paying any cash dividends
in the foreseeable future. Moreover, our ability to declare and pay cash
dividends on our common stock is restricted by covenants in our senior credit
facility and in the indentures governing our senior discount debentures and
senior subordinated notes. As a result, capital appreciation, if any, of our
common stock will be your sole source of gain for the foreseeable future.

                                       18

YOU WILL EXPERIENCE IMMEDIATE AND SUBSTANTIAL DILUTION IN THE BOOK VALUE OF YOUR
  COMMON STOCK IF YOU PURCHASE COMMON STOCK IN THE OFFERING


    Purchasers of common stock in the offering will experience immediate and
substantial dilution in the net tangible book value of their common stock. We
currently have a substantial net tangible book deficit per share of common
stock. At an assumed initial public offering price of $14.00, which is the
midpoint of the initial public offering price range set forth on the cover of
this prospectus, the dilution will be $15.69 per share in net tangible book
value of common stock from the initial public offering price, as more fully
described under "Dilution".


YOUR INTERESTS AS HOLDERS OF THE COMMON STOCK MAY CONFLICT WITH THOSE OF OUR
  CONTROLLING STOCKHOLDER


    Fox Paine & Company beneficially owns 89.6% of the outstanding shares of our
voting capital stock and after the offering will continue to own approximately
61.4%, without giving effect to the exercise of the underwriters' over-allotment
option. As a result, Fox Paine & Company has and will continue to have control
over the outcome of matters requiring stockholder approval, including the power
to:


    - elect all of our directors and the directors of our subsidiaries,

    - amend our charter or by-laws and

    - adopt or prevent mergers, consolidations or the sale of all or
      substantially all of our assets or our subsidiaries' assets.

    Fox Paine & Company also will be able to prevent or cause a change of
control relating to us. Fox Paine & Company's control over us and our
subsidiaries, and its ability to prevent or cause a change in control relating
to us, may delay or prevent a change in control of us, which could adversely
affect the market price of the common stock.

    Fox Paine & Company may in the future make significant investments in other
telecommunications companies. Some of these companies may be our competitors.
Fox Paine & Company and its affiliates are not obligated to advise us of any
investment or business opportunities of which they are aware, and they are not
restricted or prohibited from competing with us.

THE PRICE OF OUR COMMON STOCK MAY BE SUBJECT TO WIDE FLUCTUATIONS AND MAY TRADE
  BELOW THE INITIAL PUBLIC OFFERING PRICE

    Although we and the underwriters examined many factors and determined the
initial public offering price after extensive negotiation, the market price of
common stock after the offering may vary from the initial public offering price.
Fluctuations in the price of our common stock may result from factors such as
the following, some of which are beyond our control:

    - quarterly variations in our operating results,

    - operating results that vary from the expectations of securities analysts
      and investors,

    - changes in expectations as to our future financial performance, including
      financial estimates by securities analysts and investors,

    - announcements by us or our competitors of significant contracts,
      acquisitions, strategic partnerships, joint ventures or capital
      commitments,

    - changes in the status of our intellectual property and other proprietary
      rights,

    - announcements by third parties of significant claims or proceedings
      against us,

                                       19
<PAGE>
    - changes in law and regulation,

    - future sales of common stock and

    - stock market price and volume fluctuations.

    In addition, the stock market in recent years has experienced extreme price
and volume fluctuations that often have been unrelated or disproportionate to
the operating performance of companies. As a result of these fluctuations, our
common stock may trade at prices below the initial public offering price.

OUR SHARE PRICE MAY DECLINE DUE TO THE LARGE NUMBER OF SHARES ELIGIBLE FOR
  FUTURE SALE

    Sales of substantial amounts of our common stock after the offering, or the
possibility of such sales, could adversely affect the market price of our common
stock and impede our ability to raise capital through the issuance of equity
securities. See "Shares Eligible for Future Sale" for a discussion of possible
future sales of common stock.


    After this offering, we will have 31,829,273 outstanding shares of common
stock, 61.4% of which will be beneficially owned by Fox Paine, our controlling
stockholder, and we will have reserved an additional 3,332,000 shares of common
stock for issuance pursuant to outstanding stock options, of which 20,000 shares
were subject to vested options. All of the shares of common stock to be sold in
the offering will be freely tradable without restriction or further registration
under the federal securities laws unless purchased by one of our "affiliates",
as that term is defined in Rule 144 under the Securities Act of 1933. The
remaining 21,829,273 shares of outstanding common stock, representing
approximately 68.6% of the outstanding common stock upon completion of the
offering, as well as approximately 828,000 shares issuable upon exercise of
outstanding warrants, will be available for future sale subject to restrictions
on the timing, manner and volume of sales imposed by the Securities Act of 1933,
or otherwise generally, upon expiration of lockup agreements with the
underwriters 180 days after the date of this prospectus.



    In connection with the offering, we intend to file a registration statement
on Form S-8 to register 6,060,486 shares of common stock that are or will be
reserved for issuance under our stock incentive, non-employee director
compensation and stock purchase plans.

                                USE OF PROCEEDS


    Assuming an initial public offering price of $14.00 per share, which is the
midpoint of the initial public offering price range set forth on the cover of
this prospectus, and no exercise by the underwriters of their over-allotment
option, we will receive net proceeds from the offering of $129.0 million, after
deducting underwriting discounts and estimated offering expenses of $11.0
million. We intend to use $26.5 million of the net proceeds we receive to repay:


    - $10.5 million of our senior discount debentures due May 15, 2011, on which
      interest accrues at an annual rate of 13.00% and is payable semiannually,
      including $9.3 million in aggregate accreted value and a redemption
      premium of $1.2 million on these debentures and


    - $16.0 million in aggregate principal amount outstanding under our
      revolving credit facility, with an estimated weighted average annual
      interest rate of 8.26%. After this repayment, our $75.0 million revolving
      credit facility will continue to be in effect.


    We intend to use the balance of the net proceeds from the offering to fund a
portion of our capital expenditures, and for strategic investments and
acquisitions, including acquisitions of access lines, and general corporate
purposes. Depending on the timing of these expenditures, we may also use a
portion of the proceeds to repay a portion of our outstanding term loans.


    We currently expect that for the balance of 1999 and 2000, capital
expenditures will total approximately $118.0 million, including expenditures for
upgrades and replacements of switch and transmission capacity in our local
exchange operations, expansion of digital wireless capacity in our cellular
operations and the introduction of DSL services.



    We are actively pursuing selected regional acquisitions in Alaska. There are
19 local exchange carriers remaining in Alaska with an aggregate of
approximately 120,000 access lines, presenting us with the potential for
significant expansion of our network. In addition, we may pursue other selected
strategic acquisitions and investments which will complement our existing
product and service offerings.



    We have entered into an amendment to our credit agreement that will become
effective upon receipt of at least $140 million in gross proceeds from the
offering, and the preceding discussion assumes the effectiveness of that
amendment. If we receive less than $140 million in gross proceeds from the
offering, the amendment will not become effective. In that event, we intend to
seek a new amendment providing for all or a portion of the flexibility currently
contemplated.



    If the lenders under the credit agreement do not consent to that new
amendment, our use of the proceeds from the offering will differ from that
discussed above in that we will not be permitted under the credit agreement to
redeem any of our senior discount debentures. Additionally, while we will
continue to use available proceeds to reduce the outstanding balance under our
revolving credit facility and for general corporate purposes, our flexibility to
pursue strategic investments or acquisitions will be limited to the extent
currently provided in the credit agreement. In such event, we will also be
required to adjust our planned capital expenditures to satisfy covenants
contained in the credit agreement.


                                DIVIDEND POLICY


    We anticipate that we will retain all of our earnings in the foreseeable
future to finance the expansion of our business and, therefore, we do not
anticipate paying any cash dividends in the foreseeable future. Our future
dividend policy will depend on our earnings, capital requirements and financial
condition and the requirements of the financing agreements to which we may be a
party and other factors considered relevant by our board of directors. In
addition, covenants in our senior credit facility and indentures governing our
senior discount debentures and the senior subordinated notes limit our ability
to declare and pay cash dividends on our common stock.

                                 CAPITALIZATION


    The following table sets forth the capitalization of Alaska Communications
Systems Group as of September 30, 1999:


    - on an actual basis and


    - as adjusted for the sale of 10,000,000 shares of common stock in the
      offering at an initial public offering price of $14.00 per share, which is
      the midpoint of the initial public offering price range set forth on the
      cover of this prospectus, and the application of the net proceeds received
      from the sale as described under "Use of Proceeds".


    You should read this table together with "Summary Unaudited Pro Forma

- ------------------------------


(1) Additional borrowings of $6.0 million have been made under the revolving
    credit facility since September 30, 1999. The revolving credit facility
    allows for borrowings of up to $75.0 million, and $59.0 million of
    additional borrowings are available under the revolving credit facility.



(2) On May 14, 1999, we issued our senior discount debentures and warrants to
    purchase 828,261 shares of common stock for aggregate gross proceeds of
    $25.0 million. For purposes of calculating the original issue discount
    related to our senior discount debentures, $5.1 million of value was
    attributed to the warrants. The value of our senior discount debentures
    adjusted for the offering reflects repayment of 35% of their accreted value,
    net of original issue discount and exclusive of the redemption premium, as
    of September 30, 1999. On November 15, 1999, our senior discount debentures
    will have an accreted value of $26.6 million, exclusive of original issue
    discount. Assuming the amendment to our credit agreement becomes effective,
    we intend to repay 35% of the accreted value of our senior discount
    debentures at a redemption price of 113% of accreted value with proceeds
    from the offering.



(3) The calculations of shares issued and outstanding do not include
    (A) 3,328,000 shares issuable upon exercise of options granted under the
    ALEC Holdings, Inc. 1999 Stock Incentive Plan, (B) approximately 828,000
    shares issuable under outstanding warrants exercisable at $0.01 per share,
    all of which are expected to be issued in connection with the offering, and
    (C) 38,997 shares issued in October 1999. We also expect to have 2,650,000
    shares of common stock reserved for issuance under the stock incentive and
    non-employee director compensation plans we intend to adopt in connection
    with the offering. We do not expect to have any options granted outstanding
    under these plans at the time of the offering. Our stock incentive and
    non-employee director compensation plans are described under
    "Management--Compensation of Directors--Alaska Communications Systems Group,
    Inc. 1999 Non-Employee Director Stock Compensation Plan", "--ALEC Holdings,
    Inc. 1999 Stock Incentive Plan", "--Alaska Communications Systems Group,
    Inc. 1999 Stock Incentive Plan" and "Alaska Communications Systems Group,
    Inc. 1999 Employee Stock Purchase Plan".

                                    DILUTION


    Our net tangible book deficit as of September 30, 1999 was approximately
$182.7 million, or approximately $8.38 per share of common stock, based on an
aggregate of 21,790,276 shares of common stock outstanding. The number of shares
outstanding as of September 30, 1999 excludes:



    - 3,328,000 shares of common stock issuable upon exercise of outstanding
      options granted to our directors, officers, employees and consultants
      under the ALEC Holdings, Inc. 1999 Stock Incentive Plan;



    - approximately 828,000 shares issuable under outstanding warrants
      exercisable at $0.01 per share, which are expected to be issued in
      connection with the offering, and



    - 38,997 shares issued in October 1999.



We expect to have 2,650,000 shares of common stock reserved for issuance under
the stock incentive, non-employee director compensation and stock purchase plans
that we intend to adopt in connection with the offering. These plans are
described under "Management-- Compensation of Directors--Alaska Communications
Systems Group, Inc. 1999 Non-Employee Director Stock Compensation Plan",
"--Alaska Communications Systems Group, Inc. 1999 Stock Incentive Plan" and
"Alaska Communications Systems Group, Inc. 1999 Employee Stock Purchase Plan".



    "Net tangible book deficit" per share represents the amount of our total
consolidated tangible assets minus total combined liabilities, divided by the
shares of common stock outstanding, before giving effect to the sale of the
shares of common stock offered in the offering. After giving effect to the sale
of 10,000,000 shares of common stock in the offering at an assumed initial
public offering price of $14.00 per share, which is the midpoint of the initial
public offering price range set forth on the cover of this prospectus, and after
deducting estimated underwriting discounts and offering expenses of
$11.0 million, and applying the net proceeds from the offering as described
under "Use of Proceeds", our net tangible book deficit as of September 30, 1999
would have been approximately $53.7 million, or approximately $1.69 per share of
common stock. This represents an immediate decrease in net tangible book deficit
of $6.70 per share of common stock to existing stockholders and an immediate
dilution in net tangible book value of $15.69 per share of common stock to new
investors purchasing common stock in the offering at the assumed initial public
offering price. The following table illustrates this per share dilution, without
giving effect to the exercise of the underwriters' over-allotment option:

 SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA--ALASKA COMMUNICATIONS SYSTEMS
                                     GROUP



    The following table sets forth selected historical consolidated financial
data of Alaska Communications Systems Group. You should keep the following
points in mind as you read the table.



    - The selected historical consolidated operating data for the nine months
      ended September 30, 1999 include the operating results of Century's Alaska
      properties and ATU from their acquisition on May 14, 1999 through
      September 30, 1999.



    - We derived the selected historical consolidated financial data for the
      nine months ended September 30, 1999 and as of September 30, 1999 from the
      unaudited consolidated financial statements of Alaska Communications
      Systems Group, which are included elsewhere in this prospectus and which,
      in the opinion of management, include all adjustments, consisting solely
      of normal, recurring adjustments, necessary to present fairly the
      information they contain.


    - "EBITDA" is net income before interest expense, income taxes, depreciation
      and amortization. EBITDA is not intended to represent cash flow from
      operations as defined under generally accepted accounting principles and
      should not be considered as an alternative to net income as an indicator
      of our operating performance or cash flows. EBITDA is included in this
      prospectus because management believes it is a useful financial
      performance measure for comparing companies in the telecommunications
      industry in terms of operating performance and ability to satisfy debt
      service, capital expenditure and working capital requirements.


    The selected historical consolidated financial data below should be read in
conjunction with "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and the unaudited consolidated financial statements
of Alaska Communications Systems Group and the related notes which are included
elsewhere in this prospectus.

    SELECTED HISTORICAL COMBINED FINANCIAL DATA--CENTURY'S ALASKA PROPERTIES

    The following table sets forth selected historical combined financial data
of Century's Alaska properties. You should keep the following points in mind as
you read the table.

    - We derived the selected historical combined financial data for each of the
      three years in the period ended December 31, 1998 and as of December 31,
      1997 and 1998 from the audited combined financial statements and the
      related notes of Century's Alaska properties which are included elsewhere
      in this prospectus.

    - We derived the selected historical combined financial data for each of the
      two years in the period ended December 31, 1995 and as of December 31,
      1994, 1995 and 1996, from the unaudited combined financial statements of
      Century's Alaska properties which are not included in this prospectus.

    - We derived the selected combined historical financial data for each of the
      three month periods ended March 31, 1998 and 1999 and as of March 31, 1998
      and 1999 from the unaudited combined financial statements of Century's
      Alaska properties, which are included elsewhere in this prospectus and
      which, in the opinion of management, include all adjustments, consisting
      solely of normal, recurring adjustments, necessary to present fairly the
      information they contain.

    - Century acquired its Alaska properties on December 1, 1997 as part of its
      acquisition of Pacific Telecom. This acquisition was accounted for as a
      purchase, resulting in a pushdown of $208 million of goodwill to Century's
      Alaska properties.

    - The financial statements for the 11-month period ended November 30, 1997
      and prior periods have been presented on Pacific Telecom's basis of
      accounting, while the financial statements as of December 31, 1997, the
      one-month period ended December 31, 1997 and subsequent periods have been
      presented on Century's basis of accounting.

    - The financial statements of Century's Alaska properties include the
      results of the City of Fairbanks Telephone Operation from October 6, 1997,
      the date of its acquisition. This acquisition was accounted for as a
      purchase.

    - On December 31, 1997, the cellular operations in Fairbanks were sold to
      ATU. The Fairbanks cellular property had 5,497 subscribers at the time of
      the sale.

    The selected historical combined financial data below should be read in
conjunction with "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and the combined financial statements of Century's
Alaska properties and the related notes which are included elsewhere in this
prospectus.

                    SELECTED HISTORICAL FINANCIAL DATA--ATU

    The following table sets forth selected historical financial data of ATU.
You should keep the following points in mind as you read the table.

    - We derived the selected historical financial data for each of the three
      years in the period ended December 31, 1998 and as of December 31, 1997
      and 1998 from the audited financial statements and the related notes of
      ATU which are included elsewhere in this prospectus.

    - We derived the selected historical financial data for each of the two
      years in the period ended December 31, 1995 and as of December 1994, 1995
      and 1996 from the audited financial statements of ATU which are not
      included in this prospectus.

    - We derived the selected historical financial data for each of the three
      month periods ended March 31, 1998 and 1999 and as of March 31, 1998 and
      1999 from the unaudited financial statements of ATU, which are included
      elsewhere in this prospectus and which, in the opinion of management,
      include all adjustments, consisting solely of normal, recurring
      adjustments, necessary to present fairly the information they contain.

    - "Other income (expense)" includes the equity in earnings (losses) from
      minority investments.

    - During the periods presented, ATU was a public utility of the Municipality
      of Anchorage and was exempt from federal and state income taxes.

    - Net cash data includes information from ATU financial statements prepared
      in accordance with governmental accounting standards. The differences
      between governmental accounting standards and the standards promulgated by
      the Financial Accounting Standards Board, and their impact on ATU's
      financial statements are discussed in Note 1 to the financial statements
      of Municipality of Anchorage Telephone Utility Fund which are included
      elsewhere in this prospectus.

    - On June 1, 1999, as part of the consolidation of our operating and billing
      systems, we conformed the methodology by which we calculate our number of
      access lines across all of our local exchanges to that used for Century's
      Alaska properties. Due to limited data available to us, we have not
      computed any adjustments to the access lines in service for any year prior
      to 1998. If the number of access lines in service were computed using this
      method, the number of access lines as of December 31, 1998 would increase
      by 4,940 and the number of access lines as of March 31, 1999 would
      increase by 6,113. We intend to use the method used to calculate access
      lines in service for Century's Alaska properties to calculate our access
      lines in all future periods.

    The selected historical financial data below should be read in conjunction
with "Management's Discussion and Analysis of Financial Condition and Results of
Operations" and the financial statements of ATU and the related notes which are
included elsewhere in this prospectus.

         NOTES TO UNAUDITED PRO FORMA COMBINED STATEMENTS OF OPERATIONS

(a) For the periods presented, represents the estimated management fee to be
    paid to Fox Paine & Company. This management fee is equal to 1% of annual
    net income before interest expense, interest income, income taxes,
    depreciation and amortization and equity in earnings (loss) of minority
    investments, calculated without regard to the fee.

(b) Represents the increase in depreciation and amortization expense as a result
    of the increase in goodwill due to the application of purchase accounting
    and the $19.5 million purchase of fiber capacity. Goodwill is amortized over
    40 years, and the fiber capacity is depreciated over 20 years.

(c) Represents the net adjustment to interest expense as a result of the
    borrowings under our revolving credit facility, term loan facilities, senior
    subordinated notes and senior discount debentures, calculated as follows:

- ------------------------------

    (1) Represents interest on the $6.7 million that was drawn under the
       revolving credit facility of Alaska Communications Systems Holdings on
       May 14, 1999 using an assumed interest rate of 7.750%. As adjusted,
       interest reflects retirement of debt from the net proceeds of the
       offering.

    (2) Represents interest on the $150.0 million term loan A facility using an
       assumed interest rate of 7.750%.

    (3) Represents interest on the $150.0 million term loan B facility using an
       assumed interest rate of 8.000%.

    (4) Represents interest on the $135.0 million term loan C facility using an
       assumed interest rate of 8.250%.

    (5) Represents interest on the $150.0 million senior subordinated notes
       using an interest rate of 9.375%.

    (6) Represents interest on our $25.0 million senior discount debentures
       using an interest rate of 13.000%. As adjusted, interest reflects the
       retirement of debt from the net proceeds of the offering.

                                       33
<PAGE>
    (7) Represents interest on $7.5 million of long-term obligations assumed by
       us at an interest rate of 8.000%.


    (8) A 1/8% change in interest rates for the variable rate debt above would
       change interest expense by $552,000 for the year ended December 31, 1998
       and by $414,000 for the nine months ended September 30, 1999.


    (9) Deferred financing costs are amortized over the term of the related debt
       (an average life of eight years for all borrowings). As adjusted,
       amortization reflects the retirement of debt from the net proceeds of the
       offering.

(d) Represents the elimination of historical tax expense, as on a pro forma
    basis we would have been in a net loss position. No tax benefit for the net
    loss is reflected in the Unaudited Pro Forma Combined Statement of
    Operations, as we are uncertain when profitable operations will be achieved.


(e) Weighted average shares outstanding represent the shares outstanding at the
    end of the period assuming all shares had been issued on the first day of
    the period and do not include the effect of (1) 3,328,000 shares issuable
    upon exercise of options granted under the ALEC Holdings, Inc. 1999 Stock
    Incentive Plan, (2) 38,997 shares issued in October 1999 and
    (3) approximately 828,000 shares issuable under outstanding warrants
    exercisable at $.01 per share, because they would be accretive. We also
    expect to have 2,650,000 shares reserved for issuance under the stock
    incentive, non-employee director compensation and stock purchase plans we
    intend to adopt in connection with the offering. These plans are described
    under "Management--Compensation of Directors--Alaska Communications Systems
    Group, Inc. 1999 Non-Employee Director Stock Compensation Plan", "--Alaska
    Communications Systems Group, Inc. 1999 Stock Incentive Plan" and "Alaska
    Communications Systems Group, Inc. 1999 Employee Stock Purchase Plan".
    Weighted average shares outstanding as adjusted for the offering are
    increased for the 10,000,000 shares issued in the offering. Approximately
    828,000 shares issuable under outstanding warrants are also expected to be
    issued in connection with the offering.



    Assuming the amendment to our credit agreement becomes effective, we intend
to use $10.5 million of the net proceeds from the offering to redeem a portion
of our senior discount debentures. See "Use of Proceeds". At the time of the
redemption, we will record charges of $3.3 million. These charges, which will be
recorded as extraordinary items, are not included in the Unaudited Pro Forma
Combined Statements of Operations.



    Immediately following the offering, we will record compensation expense of
$1,880,000 related to the issuance on September 28, 1999 of 470,000 stock
options under the ALEC Holdings, Inc. 1999 Stock Incentive Plan and an
additional 4,000 stock options issued under that plan on October 25, 1999. All
of these options will vest immediately upon the offering. This expense is not
included in the Unaudited Pro Forma Combined Statements of Operations. For a
more detailed discussion of these stock options, see Note 4 to the Alaska
Communications Systems Group, Inc. Consolidated Financial Statements for the
Nine Months Ended September 30, 1999.



    On May 14, 1999, we granted, along with other options, performance vesting
options to purchase 653,750 shares of common stock under the ALEC Holdings, Inc.
1999 Stock Incentive Plan that will vest upon completion of the offering.
Immediately following the offering, we will record a compensation expense of
$5,129,000 related to these options, based on a market price of the shares of
$14.00, which is the midpoint of the initial public offering price range set
forth on the cover of this prospectus. This expense is not included in the
Unaudited Pro Forma Combined Statements of Operations. For a more detailed
discussion of these stock options, see Note 4 to the Alaska Communications
Systems Group, Inc. Consolidated Financial Statements for the Nine Months Ended
September 30, 1999.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

    This discussion and analysis should be read in conjunction with the
financial statements and related notes, the pro forma financial information and
the other financial information included elsewhere in this prospectus.


                      ALASKA COMMUNICATIONS SYSTEMS GROUP



    We were formed in 1998 to acquire telecommunications properties in Alaska.
In May 1999, we acquired Century's Alaska properties and ATU. Century's Alaska
properties were the incumbent provider of local telephone services in Juneau,
Fairbanks and more than 70 rural communities in Alaska and provided Internet
services to customers statewide. ATU was the largest local exchange carrier in
Alaska and provided local telephone and long distance services primarily in
Anchorage and cellular services statewide. In addition, ATU held minority
interests in companies that delivered wireless cable television, Internet access
and wholesale long distance. On September 30, 1999, we acquired a two-thirds
majority interest in Alaskan Choice Television, LLC, a wireless cable television
company in which we had previously held a one-third minority interest. On
October 6, 1999, we entered into an agreement to acquire the remaining one-third
interest in Alaskan Choice Television, together with certain FCC licenses. The
closing of this transaction is subject to the satisfaction of several
conditions, including regulatory approval of the license transfers.


    Prior to the consummation of the acquisitions of Century's Alaska properties
and ATU in May 1999, we had no operations. Accordingly, the following discussion
should be read in conjunction with our consolidated financial statements and the
related notes, the combined financial statements and the related notes of
Century's Alaska properties and the financial statements and the related notes
of ATU included in this prospectus.

    Today, we generate revenue through:

    - the provision of local telephone services, including:

     - basic local service to retail customers within our service areas,

     - wholesale service to competitive local exchange carriers,

     - network access services to interexchange carriers for origination and
       termination of interstate and intrastate long distance phone calls,

     - enhanced services,

     - ancillary services, such as billing and collection,

     - universal service payments and

     - Internet and other services;

    - the provision of wireless services; and

    - the provision of long distance services.

We also recognize our proportionate share of the net income or loss of our
minority-owned investments.


    Within the telecommunications industry, local exchange carriers have
historically enjoyed stable revenue and cash flow from local exchange operations
resulting from the need for basic telecommunications services, the highly
regulated nature of the telecommunications industry and, in the case of rural
local exchange carriers, the underlying cost recovery settlement and support
mechanisms applicable to local exchange operations. Basic local service is
generally provided at a


                                       36
<PAGE>

flat monthly rate and allows the user to place unlimited calls within a defined
local calling area. Access revenues are generated by providing interexchange
carriers access to the local exchange carrier's local network and its customers.
Universal service revenues are a subsidy paid to rural local exchange carriers
to support the high cost of providing service in rural markets. Other service
revenue is generated from ancillary services, enhanced services and Internet
access.


    Changes in revenue are largely attributable to changes in the number of
access lines, local service rates and minutes of use. Other factors can also
impact revenue, including:

    - intrastate and interstate revenue settlement methodologies,

    - authorized rates of return for regulated services,

    - whether an access line is used by a business or residential subscriber,

    - intrastate and interstate calling patterns,

    - customers' selection of various local rate plan options,

    - selection of enhanced calling services, such as voice mail, or other
      packaged products, such as cellular and Internet and

    - other subscriber usage characteristics.

    Local exchange carriers have two basic tiers of customers:

    - end users located in the local exchanges that pay for local telephone
      service including, in our case, retail, resale and unbundled network
      elements end users and

    - interexchange carriers that pay the local exchange carrier for access to
      customers located within that local exchange carrier's local service area.

    Local exchange carriers provide access service to numerous interexchange
carriers and may also bill and collect long distance charges from interexchange
carrier customers on behalf of the interexchange carriers. The amount of access
charge revenue associated with a particular interexchange carrier varies
depending upon long distance calling patterns and the relative market share of
each long distance carrier.

    Our local service rates for end users are authorized by the RCA. Authorized
rates are set by the FCC and the RCA for interstate and intrastate access
charges, respectively, and may change from time to time.


    ATU has historically provided long distance service both through leased
facilities and as a reseller of other carriers' long distance services. We
recently purchased $19.5 million of long distance fiber capacity for high speed
links within Alaska and for termination of traffic in the lower 48 states. We
have migrated long distance traffic from leased circuits onto our own network
infrastructure. As a result, we expect that in future periods operating expenses
relating to leased circuits will be lower, but depreciation relating to the
purchased capacity will be higher.

</TABLE>



    OPERATING REVENUES



    Operating revenues increased $13.3 million, or 6.4%, for the nine months
ended September 30, 1999 as compared to the nine months ended September 30,
1998. Local service, cellular and long distance revenues all increased as
compared to the prior nine-month period.



    LOCAL TELEPHONE



    Local telephone revenues, which consist of local service, network access
charges and other revenues, increased $7.2 million, or 4.0%, for the nine months
ended September 30, 1999 as compared to the nine months ended September 30,
1998. The increase in local service revenues corresponds to growth in
high-margin retail access lines of 4.7% with overall growth in access lines of
7.8%.



    CELLULAR



    Cellular revenues increased $2.7 million, or 11.8%, for the nine months
ended September 30, 1999 as compared to the nine months ended September 30,
1998, as cellular customers increased 11.9%.



    LONG DISTANCE



    Long distance revenues increased $3.4 million, or 74.6%, for the nine months
ended September 30, 1999 as compared to the nine months ended September 30, 1998
due to a 98.8% increase in long distance minutes of use.


                                       38
<PAGE>

    OPERATING EXPENSES



    Operating expenses increased $20.8 million, or 12.2%, for the nine months
ended September 30, 1999 as compared to the nine months ended September 30,
1998. Operating expenses increased to 86.7% of revenues for the nine months
ended September 30, 1999 as compared to 82.2% of revenues for the nine months
ended September 30, 1998. Adjusted for one-time and transaction related costs
associated with our acquisitions of Century's Alaska properties and ATU of
approximately $6.6 million, operating expenses would have been 83.7% of revenues
for the nine months ended September 30, 1999.



    LOCAL TELEPHONE



    Local telephone expenses increased $12.1 million, or 11.3%, for the nine
months ended September 30, 1999 as compared to the nine months ended
September 30, 1998. Plant expense, customer service expense and corporate
operations represent $10.9 million of the $12.1 million increase. All three
expense categories included one-time costs as described in the preceding
paragraph. Without these non-recurring expenses, local telephone expense would
have been $113.4 million which represents a 5.1% increase as compared to the
nine months ended September 30, 1998. The increase in customer service expense
also includes marketing and sales expense which increased as the Company
responded to competition in the local market.



    CELLULAR



    Cellular expenses increased $1.4 million, or 9.0%, for the nine months ended
September 30, 1999 as compared to the nine months ended September 30, 1998,
primarily due to the increased costs of supporting a larger customer base,
combined with the marketing expenses associated with customer sales and
retention. Increased corporate expense was also a significant component of the
increase.



    LONG DISTANCE



    Long distance expenses increased by $2.8 million, or 39.2%, but decreased as
a percentage of sales as long distance operations benefited from economies of
scale, particularly in general and administrative expenses.



    DEPRECIATION AND AMORTIZATION



    The increase of $4.4 million, or 11.0%, was due to increases in plant in
service for the six months and amortization of additional goodwill from May 14,
1999 to September 30, 1999.



    INTEREST EXPENSE



    Interest expense increased $18.3 million, or 186.6%, for the nine months
ended September 30, 1999 as compared to the nine months ended September 30, 1998
due to an increase of $611.6 million in debt incurred in connection with the
acquisitions of Century's Alaska properties and ATU.



    OTHER INCOME (EXPENSE)



    Other income (expense) for the nine months ended September 30, 1999 consists
primarily of non-recurring income and expenses ancillary to telephone operations
and losses in minority interests. Ancillary income and expense, net was
approximately $0.4 million and loss in minority interests was approximately $1.5
million. This was a 27.9% increase in net expense as compared to


                                       39
<PAGE>

the nine months ended September 30, 1998 and is primarily attributable to a
greater loss in minority interests for the current nine month period.



    NET INCOME



    The decrease in net income is primarily a result of the factors discussed
above and, in particular, the increase in operating expense as a percentage of
sales and the increase in interest expense.


                          CENTURY'S ALASKA PROPERTIES

    Century acquired its Alaska properties on December 1, 1997 as part of its
acquisition of Pacific Telecom from PacifiCorp Holdings, Inc. On October 6,
1997, prior to their acquisition by Century, Century's Alaska properties
acquired the assets of the City of Fairbanks Telephone Operation. On
December 31, 1997, Century's Alaska properties sold their Alaska rural
statistical area, or RSA, #1 B-side cellular property in Fairbanks to ATU. The
operating results of this divested property are included in the historical
operating results of Century's Alaska properties.

    The following table summarizes each component of Century's Alaska
properties' revenue sources for the years ended December 31, 1996, 1997 and 1998
and the three-month periods ended March 31, 1998 and 1999:

    OPERATING REVENUES

    Combined operating revenues increased 31.2% to $124.5 million for the year
ended December 31, 1998 as compared to $94.9 million for the year ended
December 31, 1997. Local telephone operating revenues increased 36.0% to
$121.9 million for the year ended December 31, 1998 as compared to
$89.6 million for the year ended December 31, 1997. Cellular revenues decreased
51.4% to $2.6 million for the year ended December 31, 1998 as compared to
$5.3 million for the year ended December 31, 1997. Ownership of the City of
Fairbanks Telephone Operation for a full year in 1998 versus a partial year in
1997 accounted for $21.0 million of the total $29.6 million increase in combined
operating revenues.

    LOCAL TELEPHONE

    Local telephone revenues increased 36.0% to $121.9 million for the year
ended December 31, 1998 as compared to $89.6 million for the year ended
December 31, 1997. Of this increase, $21.0 million was due to the full year of
ownership of the City of Fairbanks Telephone Operation in 1998 versus a partial
year in 1997, $4.2 million was due to higher access revenues at Telephone
Utilities of Alaska and Telephone Utilities of the Northland, $1.5 million was
due to higher local service revenues at Telephone Utilities of Alaska and
Telephone Utilities of the Northland and $0.4 million was due to higher other
revenues. The increase in local service revenues was due to a 5.6% growth in
access lines from December 31, 1997 to December 31, 1998. Growth in access
revenues was primarily the result of a higher revenue requirement due to higher
expenses for the year ended December 31, 1998 as compared to the year ended
December 31, 1997.

    CELLULAR

    Cellular revenues decreased 51.4% to $2.6 million for the year ended
December 31, 1998 as compared to $5.3 million for the year ended December 31,
1997. Improved results of the Alaska RSA #3 property increased revenues
$0.4 million for the year ended December 31, 1998 as compared to the year ended
December 31, 1997. The divestiture of the Alaska RSA #1 B-side

                                       42
<PAGE>
cellular property decreased cellular revenue by $3.1 million for the year ended
December 31, 1998 as compared to the year ended December 31, 1997.

    OPERATING EXPENSES

    LOCAL TELEPHONE

    Cost of sales and operating expenses--telephone increased 47.5% to
$72.0 million for the year ended December 31, 1998 as compared to $48.8 million
for the year ended December 31, 1997. Ownership of the City of Fairbanks
Telephone Operation for the full year 1998 versus a partial year in 1997
accounted for $15.0 million of the total increase in cost of sales and operating
expenses--telephone. The remaining increase was due primarily to higher expenses
at Telephone Utilities of Alaska and Telephone Utilities of the Northland local
telephone operations, attributable to increased costs necessary to support
growth in access lines and higher corporate allocated costs.

    CELLULAR

    Cost of sales and operating expenses--cellular decreased by 34.1% to
$2.1 million for the year ended December 31, 1998 as compared to $3.2 million
for the year ended December 31, 1997. In addition, $0.5 million of higher cost
of sales and operating expense--cellular was due to increased costs necessary to
support the increased number of customers for the Alaska RSA #3 cellular
property. The divestiture of the Alaska RSA #1 B-side cellular property
decreased expenses by $1.6 million.

    DEPRECIATION AND AMORTIZATION

    Depreciation and amortization increased $12.2 million to $30.5 million for
the year ended December 31, 1998 as compared to $18.3 million for the year ended
December 31, 1997. The increase in depreciation and amortization expense was due
to higher plant in service balances, amortization of goodwill associated with
purchase accounting, higher authorized depreciation rates effective January 1,
1998, as approved by the APUC, and a full year of ownership of the City of
Fairbanks Telephone Operation.

    INTEREST EXPENSE, NET

    Interest expense, net decreased 40.0% to $1.4 million for the year ended
December 31, 1998 as compared to $2.3 million for the year ended December 31,
1997. The decrease was due to an increase of $4.9 million in cash and cash
equivalents and an increase of $11.5 million in affiliated receivable balances
at December 31, 1998 as compared to December 31, 1997.

    OTHER INCOME (EXPENSE)

    Other income (expense) is related primarily to non-recurring and
non-operating income and expenses. For the year ended December 31, 1998, other
income (expense) was $356,000 as compared to $(245,000) for the year ended
December 31, 1997.

    INCOME TAXES

    Income taxes increased 8.7% to $9.2 million for the year ended December 31,
1998 as compared to $8.5 million for the year ended December 31, 1997. The
increase in income taxes was due to increased taxable income in 1998 as compared
to 1997.

                                       43
<PAGE>
    NET INCOME

    As a result of the factors described above, net income decreased
$3.8 million to $9.6 million for the year ended December 31, 1998 as compared to
$13.4 million for the year ended December 31, 1997.

    EBITDA

    As a result of the factors described above, EBITDA increased by
$8.2 million to $50.7 million for the year ended December 31, 1998 as compared
to $42.6 million for the year ended December 31, 1997. In particular, an
increase in local telephone customers as represented by an increase in access
lines more than offset the effects of a decline in cellular customers.

CENTURY'S ALASKA PROPERTIES--FISCAL YEAR ENDED DECEMBER 31, 1997 COMPARED TO
  FISCAL YEAR ENDED DECEMBER 31, 1996

    OPERATING REVENUES

    Combined operating revenues increased 17.5% to $94.9 million for the year
ended December 31, 1997 as compared to $80.8 million for the year ended
December 31, 1996. Local telephone operating revenues increased 18.0% to
$89.6 million for the year ended December 31, 1997 as compared to $76.0 million
for the year ended December 31, 1996. Cellular revenues increased 9.9% to
$5.3 million for the year ended December 31, 1997 as compared to $4.8 million
for the year ended December 31, 1996. Ownership of the City of Fairbanks
Telephone Operation from October 6, 1997 through December 31, 1997 accounted for
$7.8 million of the total $14.1 million increase in combined operating revenues.

    LOCAL TELEPHONE

    Local telephone revenues increased 18.0% to $89.6 million for the year ended
December 31, 1997 as compared to $76.0 million for the year ended December 31,
1996. Of this increase, $7.8 million was due to partial year ownership of the
City of Fairbanks Telephone Operation in 1997, $1.2 million was due to higher
access revenues at Telephone Utilities of Alaska and Telephone Utilities of the
Northland, and $2.0 million was due to higher local service and other revenues
at Telephone Utilities of Alaska and Telephone Utilities of the Northland. The
increase in local service revenues was due to a 6.0% growth in access lines and
higher enhanced services revenue, in each case, without giving effect to the
City of Fairbanks Telephone Operation acquisition. Growth in access revenues was
primarily the result of a higher revenue requirement due to higher expenses for
the year ended December 31, 1997 as compared to the prior year.

    CELLULAR

    Cellular revenues increased 9.9% to $5.3 million for the year ended
December 31, 1997 as compared to $4.8 million for the year ended December 31,
1996. Improved results were primarily due to an increase in subscribers from
December 31, 1996 to December 31, 1997.

    OPERATING EXPENSES

    LOCAL TELEPHONE

    Cost of sales and operating expenses--telephone increased 16.7% to
$48.8 million for the year ended December 31, 1997 as compared to $41.8 million
for the year ended December 31, 1996. Ownership of the City of Fairbanks
Telephone Operation for part of the year in 1997 accounted for $4.4 million of
the total increase. The remaining increase is due primarily to higher expenses
for

                                       44
<PAGE>
Telephone Utilities of Alaska and Telephone Utilities of the Northland local
telephone operations, attributable to increased costs necessary to support
growth in access lines.

    CELLULAR

    Cost of sales and operating expenses--cellular decreased 4.5% to
$3.2 million for the year ended December 31, 1997 as compared to $3.4 million
for the year ended December 31, 1996.

    DEPRECIATION AND AMORTIZATION

    Depreciation and amortization increased 19.2% to $18.3 million for the year
ended December 31, 1997 as compared to $15.3 million for the year ended
December 31, 1996. Ownership of the City of Fairbanks Telephone Operation for
part of the year in 1997 resulted in $2.1 million of the total increase. The
remaining portion of the total increase was due to higher plant in service
balances in 1997 as compared to 1996.

    INTEREST EXPENSE, NET

    Interest expense, net increased 17.2% to $2.3 million for the year ended
December 31, 1997 as compared to $2.0 million for the year ended December 31,
1996.

    OTHER INCOME (EXPENSE)

    Other income (expense) is related primarily to non-recurring and
non-operating income and expenses. For the year ended December 31, 1996, these
items resulted in other income (expense) of $0.0 million as compared to $(0.2)
million for the year ended December 31, 1997. This increase was due principally
to increased Internet revenues and increased payphone, equipment sales and
rental activity.

    INCOME TAXES

    Income taxes increased 25.9% to $8.5 million for the year ended
December 31, 1997 as compared to $6.7 million for the year ended December 31,
1996. The increase in income taxes was due to increased taxable income in 1997
as compared to 1996.

    NET INCOME

    As a result of the factors described above, net income increased
$1.9 million to $13.4 million for the year ended December 31, 1997 as compared
to $11.5 million for the year ended December 31, 1996.

    EBITDA

    As a result of the factors described above, EBITDA increased $7.0 million to
$42.6 million for the year ended December 31, 1997 as compared to $35.6 million
for the year ended December 31, 1996. In particular, this increase was the
result of increases in local telephone and cellular customers.

</TABLE>

    ATU's operating expenses are categorized as: cost of sales and operating
expenses--local telephone; cost of sales and operating expenses--cellular; cost
of sales and operating expenses--long distance; and depreciation and
amortization. Cost of sales and operating expenses--local telephone are those
operating expenses incurred by ATU in connection with its local telephone
business, including the operation of its central offices and outside plant
facilities and related operations, customer service, marketing and other general
and administrative expenses and corporate expenses. These expenses included
allocations from the Municipality of Anchorage totaling $3.2 million,
$3.7 million and $3.2 million for the years ended December 31, 1996, 1997 and
1998, respectively. Management considers these expenses to be comparable to
those which would have been incurred on a stand-alone basis and to those we
expect to incur in future periods. Cost of sales and operating
expenses--cellular are those operating expenses incurred by ATU in connection
with the operation of its wireless facilities and transmission of wireless
services, customer service, marketing and other general and administrative
expenses and corporate expenses. Cost of sales and operating expenses--long
distance includes operating expenses incurred by ATU in connection with the
provisioning of long distance services.

ATU--THREE MONTHS ENDED MARCH 31, 1999 COMPARED TO THE THREE MONTHS ENDED
  MARCH 31, 1998

    OPERATING REVENUES

    Operating revenues increased $3.0 million, or 8.2%, for the three months
ended March 31, 1999 as compared to the three months ended March 31, 1998. ATU
reported revenue growth in all three service categories: local telephone,
cellular and long distance.

    LOCAL TELEPHONE

    Local telephone revenues, which consist of local service, network access
charges and other revenues, increased $629,000, or 2.1%, for the three months
ended March 31, 1999 as compared to the three months ended March 31, 1998. Local
service revenues decreased $669,000, or 5.2%, as a result of a 3.6% decrease in
retail access lines. Local service revenues include revenues for ATU's retail
local telephone service to business and residential customers and wholesale
customers that resell ATU's local telephone service. The decrease in retail
access lines was primarily due to the introduction of competition in ATU's
service area.

                                       46
<PAGE>
    Network access revenues increased $2.7 million, or 33.0%, for the three
months ended March 31, 1999 as compared to the three months ended March 31,
1998, due primarily to prior period revenues which had been reserved in
connection with various regulatory matters that have been resolved.

    Other revenues decreased $1.4 million, or 15.4%, for the three months ended
March 31, 1999 as compared to the three months ended March 31, 1998.

    CELLULAR

    Cellular revenues increased $831,000, or 14.1%, for the three months ended
March 31, 1999 as compared to the three months March 31, 1998. The number of
subscribers increased from 54,436 at March 31, 1998 to 63,779 at March 31, 1999.

    LONG DISTANCE

    Long distance revenues increased $1.5 million, or 134.5%, for the three
months ended March 31, 1999 as compared to the three months ended March 31, 1998
principally due to a 161.1% growth in minutes of use.

    OPERATING EXPENSES

    LOCAL TELEPHONE

    Cost of sales and operating expenses--telephone increased $613,000, or 3.4%,
for the three months ended March 31, 1999 as compared to the three months ended
March 31, 1998 due to a number of factors including increased labor and
consulting related to new information systems, increased customer service
expense and an increase in sales and marketing expense as a response to the
opening of the Anchorage local market to competition.

    CELLULAR

    Cost of sales and operating expenses--cellular increased $692,000, or 17.1%,
for the three months ended March 31, 1999 as compared to the three months ended
March 31, 1998 primarily due to the increase costs of supporting a larger
customer base.

    LONG DISTANCE

    Cost of sales and operating expenses--long distance increased $1.3 million,
or 70.9%, for the three months ended March 31, 1999 as compared to the three
months ended March 31, 1998. Expenses rose at a lower rate than revenues due to
economies of scale. Since ATU was not a facilities-based carrier, a primary
component of long distance cost of sales was the semi-fixed expense of leased
lines over a range of capacity. In addition, selling, general and administrative
expense, as a percentage of revenues, was significantly lower for the three
months ended March 31, 1999 as compared to the three months ended March 31,
1998.

    DEPRECIATION AND AMORTIZATION

    Depreciation and amortization expense increased $335,000, or 4.7%, for the
three months ended March 31, 1999 as compared to the three months ended
March 31, 1998 primarily due to increases in plant in service balances.

    INTEREST EXPENSE, NET

    Interest expense, net decreased $255,000, or 13.9%, for the three months
ended March 31, 1999 as compared to the three months ended March 31, 1998 due to
the decrease in outstanding long-term debt.

<PAGE>
    OTHER INCOME (EXPENSE)


    Other income (expense) includes equity in earnings (loss) of minority
interests and other income and expenses ancillary to telephone operations. Other
income decreased by $240,000 for the three months ended March 31, 1999 as
compared to the three months ended March 31, 1998.


    NET INCOME AND EBITDA

    Net income increased $29,000, or 0.8%, and EBITDA increased $109,000, or
0.9%, as a result of the factors described above. In particular, the increase in
the customer base for cellular and long distance services and the increase in
revenues from the resale of unbundled network elements more than offset the
competition-driven decrease in local telephone retail customers.

ATU--FISCAL YEAR ENDED DECEMBER 31, 1998 COMPARED TO FISCAL YEAR ENDED
  DECEMBER 31, 1997

    OPERATING REVENUES

    Operating revenues increased 12.3% to $157.1 million for the year ended
December 31, 1998 as compared to $139.9 million for the year ended December 31,
1997. ATU reported revenue growth in all three service categories: local
telephone, cellular and long distance.

    LOCAL TELEPHONE

    Local telephone revenues, which consist of local service, network access
charges and other revenues, increased 3.9% to $121.1 million for the year ended
December 31, 1998 as compared to $116.6 million for the year ended December 31,
1997. Local service revenues decreased 2.2% to $50.9 million for the year ended
December 31, 1998 as compared to $52.0 million for the year ended December 31,
1997 as a result of a decrease in retail access lines. Local service revenues
include revenues for ATU's retail local telephone service to business and
residential customers and wholesale customers that resell ATU's local telephone
service. Although the total number of access lines increased from 158,486 at
December 31, 1997 to 168,536 at December 31, 1998, retail access lines decreased
14,492 from 150,720 at December 31, 1997 to 136,228 at December 31, 1998,
principally as a result of the introduction of competition in ATU's service
area. The number of access lines made available to competitors increased from
7,766 at December 31, 1997 to 32,308 at December 31, 1998. This decrease in
retail access lines resulted in a decrease in local service revenues.

    Network access revenues increased 1.1% to $34.7 million for the year ended
December 31, 1998 as compared to $34.4 million for the year ended December 31,
1997. Market share losses relating to increased sales by competitors reduced
network access revenues by $1.9 million in 1998. We expect this competition to
continue. This decrease was partially offset by $2.4 million in higher
intrastate network access revenues from the settlement of a prior year access
charge dispute.

    Other revenues increased 17.5% to $35.5 million for the year ended
December 31, 1998 as compared to $30.2 million for the year ended December 31,
1997. This increase was primarily attributable to higher revenues from unbundled
network element interconnection and directory advertising. Revenues from monthly
charges paid by competing carriers for unbundled network element interconnection
are accounted for as other revenue.

    CELLULAR

    Cellular revenues increased 33.8% to $29.2 million for the year ended
December 31, 1998 as compared to $21.8 million for the year ended December 31,
1997. The increase was due to an increase in the number of cellular subscribers
in Anchorage and Alaska RSA #2, as well as the acquisition of the Alaska RSA #1
B-side cellular property on January 1, 1998. The number of subscribers increased
from 47,538, excluding the Alaska RSA #1 B-side property, at December 31, 1997
to 63,627 at December 31, 1998. The Fairbanks property increased from 5,497
subscribers at January 1, 1998 to 9,064 at December 31, 1998. Average revenue
per customer per month remained stable at $42 per customer per month.

    LONG DISTANCE

    Long distance revenues increased 342.2% to $6.8 million for the year ended
December 31, 1998 as compared to $1.5 million for the year ended December 31,
1997 principally due to customer growth. The number of customers increased to
25,670 customers at December 31, 1998 from approximately 10,600 customers at
December 31, 1997.

    OPERATING EXPENSES

    LOCAL TELEPHONE

    Cost of sales and operating expenses--telephone decreased marginally to
$74.2 million for the year ended December 31, 1998 as compared to $75.0 million
for the year ended December 31, 1997. Product sales and advertising expenses
increased $2.4 million in 1998 due to increased advertising campaigns resulting
from heightened competition in the local telephone market in 1998. These
increased expenses were offset by $3.5 million of reduced expenses, primarily
due to lower labor expenses associated with reduced full-time local telephone
employee levels in 1998 as compared to 1997.

    CELLULAR

    Cost of sales and operating expenses--cellular increased 38.1% to
$20.0 million for the year ended December 31, 1998 as compared to $14.5 million
for the year ended December 31, 1997. An increase in customers from 47,538 at
December 31, 1997 to 63,627 at December 31, 1998 resulted in increases in sales
and marketing, general and administrative and other operating expenses. Of the
$5.5 million increase in cost of sales and operating expenses--cellular,
$2.1 million was due to the operation of the newly acquired Alaska RSA #1 B-side
cellular property for a full year in 1998.

    LONG DISTANCE

    Cost of sales and operating expenses--long distance increased 123.8% to
$10.4 million for the year ended December 31, 1998 as compared to $4.6 million
for the year ended December 31, 1997. Increased expenses were due to additional
dedicated facilities leases, access payments, advertising and administrative
expenses to support increasing long distance traffic volumes. Traffic volumes
increased due to increases in the total number of long distance customers. As a
result, ATU's long distance operations incurred losses of $3.7 million in 1998
and $3.2 million in 1997.

    DEPRECIATION AND AMORTIZATION

    Depreciation and amortization expense increased 10.3% to $29.6 million for
the year ended December 31, 1998 as compared to $26.8 million for the year ended
December 31, 1997. Increases in plant in service balances and goodwill
amortization accounted for the increase. Higher

                                       49
<PAGE>
depreciation and amortization expense of $1.5 million in the local telephone
operations and $1.3 million in the cellular and long distance operations was
incurred in 1998.

    INTEREST EXPENSE, NET

    Interest expense, net decreased 5.0% to $6.4 million for the year ended
December 31, 1998 as compared to $6.8 million for the year ended December 31,
1997. Interest expense increased by $1.1 million as a result of additional
outstanding long-term obligations associated with a bond issuance in 1998.
Increases in interest income from higher cash balances served to offset higher
interest expense. Reversal of previously accrued interest expense for revenue
that had been reserved in prior periods but recognized in 1998 reduced interest
expense for the year ended December 31, 1998 by $0.4 million.

    OTHER INCOME (EXPENSE)


    Other income (expense) includes equity in earnings (loss) of minority
interests and nonoperating other income and expenses ancillary to telephone
operations. ATU recognized losses in its minority investments of $2.9 million
for the year ended December 31, 1998 compared to earnings of $0.2 million for
the year ended December 31, 1997. For the year ended December 31, 1998, ATU
incurred $1.1 million in proportional losses from its minority investments, and
wrote down $1.5 million and $0.4 million of its investments in Alaskan Choice
Television and Internet Alaska, Inc., respectively.


    NET INCOME AND INCOME TAXES

    As a result of the factors described above, net income increased
$1.5 million to $13.6 million for the year ended December 31, 1998 as compared
to $12.1 million for the year ended December 31, 1997. Because ATU was a public
utility of the Municipality of Anchorage, it was exempt from U.S. federal and
state income taxes.

    EBITDA

    As a result of the factors described above, EBITDA increased $3.9 million to
$49.6 million for the year ended December 31, 1998 as compared to $45.7 million
for the year ended December 31, 1997. In particular, the increase in the
customer base for cellular and long distance services and the increase in
revenues from the resale of unbundled network elements more than offset the
competition-driven decrease in local telephone retail customers.

ATU--FISCAL YEAR ENDED DECEMBER 31, 1997 COMPARED TO FISCAL YEAR ENDED
  DECEMBER 31, 1996

    OPERATING REVENUES

    Operating revenues increased 7.4% to $139.9 million for the year ended
December 31, 1997 as compared to $130.3 million for the year ended December 31,
1996. ATU reported revenue growth in all three service categories: local
telephone, cellular and long distance.

    LOCAL TELEPHONE

    Local telephone revenues increased 2.8% to $116.6 for the year ended
December 31, 1997 as compared to $113.4 million for the year ended December 31,
1996. Local service revenues increased 5.2% to $52.0 million for the year ended
December 31, 1997 as compared to $49.5 million for the year ended December 31,
1996. The increase in local service revenues was

                                       50
<PAGE>
primarily due to a 2.4% increase in access lines and increases in penetration of
enhanced services, such as caller ID and call forwarding. Access revenues
declined $0.4 million for the year ended December 31, 1997 due to lower
intrastate access revenues. Other revenues increased 3.4% to $30.2 million for
the year ended December 31, 1997 as compared to $29.2 million for the year ended
December 31, 1996, principally as a result of the commencement of unbundled
network element interconnection, resulting in the sale by ATU of unbundled
network elements to a competitor, and directory advertising revenues.

    CELLULAR

    Cellular revenues increased 29.3% to $21.8 million for the year ended
December 31, 1997 as compared to $16.9 million for the year ended December 31,
1996. The increase was principally attributable to a 26.3% increase in the
number of subscribers, from 37,651 at December 31, 1996 to 47,538 at
December 31, 1997, excluding the Alaska RSA #1 B-Side cellular property which
was acquired on January 1, 1998.

    LONG DISTANCE

    Long distance revenues increased to $1.5 million for the year ended
December 31, 1997 as compared to $2,000 for the year ended December 31, 1996.
The increase was attributable to the commencement of the long distance business
in the fall of 1996.

    OPERATING EXPENSES

    LOCAL TELEPHONE

    Cost of sales and operating expenses--telephone decreased 1.3% to
$75.0 million for the year ended December 31, 1997 as compared to $76.0 million
for the year ended December 31, 1996. The decrease is primarily attributable to
lower labor expense as a result of a reduction in the number of employees and
lower expenses from regulatory consulting services.

    CELLULAR

    Cost of sales and operating expenses--cellular increased 16.8% to
$14.5 million for the year ended December 31, 1997 as compared to $12.4 million
for the year ended December 31, 1996. The increase is attributable to increases
in the number of employees to support growth in the customer base and increased
advertising expenses.

    LONG DISTANCE

    Cost of sales and operating expenses--long distance increased $4.1 million
to $4.6 million for the year ended December 31, 1997 as compared to
$0.5 million for the year ended December 31, 1996. The increase was due to
start-up expenses associated with commencing long distance operations, including
higher switching, facilities lease and access expenses to support the larger
base of customers.

    DEPRECIATION AND AMORTIZATION

    Depreciation expense increased 30.9% to $26.8 million for the year ended
December 31, 1997 as compared to $20.5 million for the year ended December 31,
1996. The higher depreciation expense was attributable to higher telephone plant
in service, as well as higher depreciation rates authorized by the APUC that
became effective January 1, 1997.

                                       51
<PAGE>
    INTEREST EXPENSE, NET

    Interest expense, net remained relatively unchanged. Higher interest expense
from additional outstanding long-term debt balances was offset by higher
interest income associated with higher average cash balances.

    OTHER INCOME (EXPENSE)

    Other income (expense) includes minority investment earnings of
$0.2 million and other expense of $0.3 million for the year ended December 31,
1997 as compared to other expense of $0.2 million for the year ended
December 31, 1996.

    NET INCOME

    As a result of the factors described above, net income decreased
$1.8 million to $12.1 million for the year ended December 31, 1997 as compared
to $13.9 million for the year ended December 31, 1996. Because ATU was a public
utility of the Municipality of Anchorage, it was exempt from U.S. federal and
state income taxes.

    EBITDA

    As a result of the factors described above, EBITDA increased $4.5 million to
$45.7 million for the year ended December 31, 1997 as compared to $41.2 million
for the year ended December 31, 1996. In particular, our customer base grew in
local, cellular and long distance services.

YEAR 2000

    Some of our older computer programs identify years with two digits instead
of four. This may cause problems because these programs may recognize the year
2000 as the year 1900. These problems could result in a system failure or
miscalculations disrupting operations, including a temporary inability to
process transactions, send invoices or engage in similar, normal business
activities. In addition, we face the risk that suppliers of products, services
and systems purchased by us do not have business systems or products that comply
with the year 2000 requirements.

    While we believe that the conversions or installations of replacement
systems will proceed smoothly, we cannot assure you that there will not be
interruptions or failures in our systems or in the systems of our suppliers. The
telecommunications industry is highly susceptible to the year 2000 issue. Should
the year 2000 issue cause problems across our infrastructure, service could be
interrupted. These events, if they occur, could materially adversely affect our
financial condition and results of operations.

    In order to understand our vulnerability to the year 2000 issue, we
conducted a comprehensive systems assessment of our year 2000 compliance during
the process of evaluating the acquisitions of Century's Alaska properties and
ATU. Many of our systems have also been represented by the respective vendors of
these systems to be year 2000 compliant, and both Century's Alaska properties
and ATU have initiatives in progress that we believe will address all
outstanding year 2000 issues.

    As of January 1, 1999, ATU completed its installation of an integrated
financial and accounting system. On March 12, 1999, ATU completed its
installation of Saville, a state-of-the-art customer care and billing system.
MACtel and ATU Long Distance will continue to operate their existing financial
management and billing systems. With respect to carrier access billing, ATU has
completed the transition to Century's Alaska properties' existing systems. Each
of the foregoing systems has been represented by the vendor to be year 2000
compliant.

                                       52
<PAGE>
    We have recently converted Century's Alaska properties' customer care and
billing systems to ATU's Saville platform. Century's Alaska properties recently
completed their installation of Platinum, an integrated financial and accounting
application. Facilities management and repair support systems for Century's
Alaska properties have also transitioned to ATU platforms, which have been
represented by the vendors as year 2000 compliant.


    Since January 1, 1999, we have spent approximately $22.3 million to upgrade
and maintain our information technology systems to make them year 2000
compliant. Additional costs required in order to make our information technology
systems year 2000 compliant by the end of December 1999 are not expected to be
material.



    Upgrades required to make ATU's network equipment year 2000 compliant are
mostly complete, with remaining upgrades expected to be finished by mid-November
1999. All of ATU's central office switches have been upgraded to year 2000
certified release levels. Upgrades required to make Century's Alaska properties'
network equipment year 2000 compliant are mostly complete, with remaining
upgrades expected to be finished by mid-November 1999. All of Century's Alaska
properties' central office switches have been upgraded to year 2000 certified
release levels.



    Upgrades required for MACtel's and Century's Alaska properties' cellular
switching networks are mostly complete, with remaining upgrades scheduled to be
completed by our third party switching vendor by mid-December.



    Given the progress made to date, we do not anticipate delays in finalizing
and implementing year 2000 readiness solutions by December 1999. We cannot
accurately estimate the uncertainty of completing our year 2000 readiness plan,
particularly as it relates to any failure by third parties that have material
relationships with us and fail to achieve their own year 2000 readiness. We have
in the past and will continue to obtain assurances from third parties that their
systems are or will be year 2000 compliant no later than the end of
December 1999. Any failures by these third parties to appropriately address
their own year 2000 readiness challenges could materially adversely affect our
financial condition and results of operations.


    We believe that the following several situations make up our most reasonably
likely worst case scenario:

    FAILURE OF ELECTRICAL POWER SUPPLIES.  Although most of our major switching
and information systems have emergency standby power supplies, in the event of
long-term power disruption we may be required to shut down our switching and
computer equipment. We believe the larger electrical utilities that provide
service to us are pursuing year 2000 readiness strategies. However, electric
utilities serving smaller rural communities may be particularly exposed to year
2000 readiness issues.

    DISRUPTION OF SWITCHING AND INFORMATION TECHNOLOGY INFRASTRUCTURE.  The most
significant risks related to our switching and information technology systems
are:

    - the inability of our customers to make and receive calls,

    - the inability of our cell sites, switching centers and other interfaces to
      process and record call details of local telephone, long distance and
      cellular traffic accurately and

    - the inability of our billing systems to report and bill customers for
      phone usage accurately.

    We believe that we have adequately addressed each of these risks in our year
2000 readiness plan.

                                       53
<PAGE>
    INABILITY OF LARGE CUSTOMERS TO PAY INVOICES.  Our largest customers are
interexchange carriers that are customers, vendors and competitors in some of
our markets. If interexchange carriers experience year 2000 readiness problems,
we may experience delays in collection of outstanding receivables and a decrease
in the cash available to fulfill our obligations.

    We are developing contingency plans for potential year 2000 disruptions. We
are closely monitoring our year 2000 readiness plan and have developed
preliminary contingency plans for the most critical aspects of our year 2000
readiness plan. Details of these plans will be further developed and will depend
on our final assessment of the relevant situation and potential alternative
strategies.

LIQUIDITY AND CAPITAL RESOURCES


    We have funded our operations primarily from the sale of stock, debt
financing and operations. The nine months ended September 30, 1999 include
operations from acquired telephone operations for the period from May 15, 1999
to September 30, 1999. For this period, our cash flows from operating activities
were $21.4 million. Significant cashflows from the issuance of debt and stock
were used for the acquisitions of Century's Alaska properties and ATU and, to a
lesser extent, for capital expenditures. At September 30, 1999, we had
approximately $6.5 million in working capital, including approximately
$1.6 million in cash and cash equivalents. We also had $59.0 million of
remaining capacity under the $75.0 million revolving credit facility as of
September 30, 1999.



    Our initial debt borrowings and equity contributions were sufficient to fund
the consummation of the acquisitions of Century's Alaska properties and ATU and
the purchase of fiber capacity. On May 14, 1999 Alaska Communications Systems
Holdings entered into a $435.0 million credit agreement and issued
$150.0 million aggregate principal amount of senior subordinated notes in a
private placement, and we issued senior discount debentures and warrants for
$25.0 million in gross proceeds in a private placement, and received an equity
capital infusion in the amount of $121.2 million. As a result of the financing
for these acquisitions, as of September 30, 1999 we had $615.4 million of
long-term debt. Interest payments on borrowings under the senior credit
facility, our senior discount debentures and the senior subordinated notes, as
well as amortization of borrowings under the senior credit facility, represent
significant obligations of ours and Alaska Communications Systems Holdings.
Interest on our senior discount debentures and the senior subordinated notes is
payable semiannually. Interest on borrowings under the senior credit facility is
payable quarterly, and the senior credit facility requires annual principal
payments commencing on May 14, 2002.



    The local telephone network requires the timely maintenance of plant and
infrastructure. Our local network is of high quality and is technically advanced
and will have relatively predictable annual capital needs. Our historical
capital expenditures have been significant. The construction and geographic
expansion of our cellular network required a substantial amount of capital. The
implementation of our long distance and interexchange network strategy is also
capital intensive. We recently purchased fiber capacity for $19.5 million, which
was funded with monies borrowed to finance the acquisitions of Century's Alaska
properties and ATU. This purchase will enable us to use our own leased
facilities in developing our business. We also have agreed to purchase
additional fiber capacity for $19.5 million in the second quarter of 2001. In
addition to the purchase of fiber capacity, we anticipate, subject to
effectiveness of the credit agreement amendment, total capital expenditures of
approximately $28.2 million for the remainder of 1999, and approximately
$90.0 million in 2000, which we expect to fund through internally generated cash
flow, a portion of the net proceeds from the offering and additional borrowings
under our revolving credit facility. If we are unable to amend our credit
agreement as expected, we anticipate capital expenditures of $18.8 million for
the remainder of 1999 and of approximately $70.0 million in 2000.


                                       54
<PAGE>
    Our capital requirements may change, however, due to, among other things:

    - the availability of additional fiber capacity,

    - our decision to pursue specific acquisition opportunities,

    - changes in technology,

    - the effects of competition or

    - changes in our business strategy.


    Any of these changes could require additional financing that might not be
available or, if available, might not be on terms favorable to us. Our ability
to satisfy our capital requirements will be dependent upon our future financial
performance, which is, in turn, subject to future economic conditions and to
financial, business and other factors, many of which are beyond our control.



    Subsequent to the acquisition of ATU and Century's Alaska properties, we
issued 1,746,402 shares of our common stock, including the sale of 1,624,907
shares to Cook Inlet Region, Inc. for $10.0 million in cash. Proceeds of the
stock sales were subsequently contributed to Alaska Communications Systems
Holdings as additional equity capital. In connection with Cook Inlet's
investment, it became a party to the stockholders' agreement, which is described
under "Management--Stockholders' Agreement".


    On July 24, 1999 we entered into a hedging transaction which fixed at 5.99%
the underlying variable rate on one-half of the borrowings under the senior
credit facility, or $217.5 million, for a three-year period.


    On September 30, 1999, we acquired an additional one-third interest in
Alaskan Choice Television for $1.9 million, increasing our ownership to a
two-thirds majority interest. On October 6, 1999, we entered into an agreement
to acquire the remaining one-third interest and expect that the acquisition will
be completed by year-end 1999.


    We believe that we will have sufficient working capital provided by
operations and borrowings under our existing revolving credit facility to fund
our operations and capital expenditures over the next 12 months.

EFFECT OF NEW ACCOUNTING STANDARDS


    SFAS No. 133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES,
was issued in June 1998. SFAS No. 133 establishes standards for the recognition
and measurement of derivatives and hedging activities. This statement, as
amended, is effective for fiscal years beginning after June 15, 2000. We are
currently analyzing the impact SFAS No. 133 will have on our financial
statements.


OUTLOOK

    We expect the current demand for telecommunications services in Alaska to
continue to grow, particularly as a result of:

    - continuing growth in demand for core telephone services and enhanced
      service offerings,

    - increased access line demand stemming from growth in population and the
      demand for multiple lines,

    - increases in demand for wireless services and

                                       55
<PAGE>
    - growth in demand for DSL and Internet access services due to higher
      business and consumer bandwidth needs for Internet and data services.

    We believe that we will be able to capitalize on this demand through our
diverse service offerings and a focused sales and marketing approach.


    There are currently a number of regulatory proceedings underway at the state
and federal levels that could have a significant impact on our operations.



    At the state level:



    - the RCA recently terminated the rural exemptions of our rural local
      exchange carriers, triggering interconnection obligations under the
      Telecommunications Act from which we had previously been exempt; and



    - the RCA has indicated that it does not intend to determine rates and terms
      for interconnection through tariff processes and has ordered our rural
      local exchange carriers to negotiate with potential competitors for the
      purpose of establishing the terms and conditions of interconnection in
      their service areas, subject to arbitration at the request of any party at
      any time after December 10, 1999 if the parties are unable to reach
      agreement.



    At the federal level:



    - in October 1998 the FCC initiated proceedings, but has not reached a
      decision, regarding the appropriate rate of return to be applied for
      federal rate-making purposes to companies like us which are not subject to
      price cap regulation;



    - in September 1999 the FCC revised its list of unbundled network elements
      applicable to our ongoing negotiations regarding interconnection,
      excluding some elements but increasing the number of sub-elements
      associated with the local loop.



    This is not an exhaustive list of regulatory matters that could affect our
business, and we cannot predict the impact of these or future regulatory
developments on any of our businesses.



    The telecommunications industry is extremely competitive, and we expect
competition to intensify in the future. As the incumbent local exchange carrier,
we face competition mainly from resellers, local providers who lease unbundled
network elements from us and, to a lesser degree, from facilities-based
providers of local telephone services. In addition, as a result of the RCA's
recent affirmation of the APUC's termination of our rural exemptions, we may be
required to provide interconnection elements and/or wholesale discounted
services to competitors in all or some of our rural service areas. Moreover,
while cellular telephone services have historically complemented traditional
local exchange carrier services, we anticipate that existing and emerging
wireless technologies may increasingly compete with local exchange carrier
services. In wireless services, we currently compete with at least one other
cellular provider in each of our wireless service areas. In long distance, we
currently have less than 2.5% of total long distance revenues in Alaska and we
face competition from the two major long distance providers in Alaska. In the
highly competitive business for Internet access services, we currently compete
with a number of established online service companies, interexchange carriers
and cable companies.


    The telecommunications industry is subject to continuous technological
change. We expect that new technological developments in the future will
generally serve to enhance our ability to provide service to our customers.
However, these developments may also increase competition or require us to make
significant capital investments to maintain our leadership position in Alaska.

                               INDUSTRY OVERVIEW

OVERVIEW

    In recent years, the telecommunications industry has undergone rapid change
due to economic growth, technological advancements, infrastructure improvements
and regulatory changes, all of which have increased demand and competition for
telecommunications services. The Alaskan telecommunications industry is
influenced by many of these factors, and Alaska's unique characteristics further
enhance the need for telecommunications services. Alaska is characterized by its
large geographic size, widely dispersed population and large distance between
urban areas. Over 60% of the state's population resides in its three largest
cities: Anchorage, Juneau and Fairbanks. Alaska lacks an effective ground
transportation infrastructure and many of the state's communities are accessible
only by air or water. As a result, Alaskan residents are particularly dependent
on telecommunications to access resources and information.

    Alaskan telecommunications operators use a variety of technologies,
including traditional copper wire, fiber optic cable, digital microwave and
satellite-based communications, particularly in remote communities, to provide
telecommunications services, including local telephone, wireless, long distance,
data and Internet services.

LOCAL TELEPHONE OVERVIEW

    The U.S. local telephone industry is subject to significant regulation from
both the FCC and state authorities. The U.S. local telephone industry is
composed of a few large, well-known companies, including the regional Bell
operating companies and GTE Corporation, and numerous small, independent
telephone companies. Large incumbent local exchange carriers generate the vast
majority of the estimated $100 billion in annual local exchange revenues and own
a substantial majority of the access lines. A majority of the small, independent
telephone companies operate in sparsely populated rural areas with limited
competition due to the unfavorable economics of constructing and operating a
competing network in those areas.

    Local telephone services traditionally offered by local telephone companies
include:

    - basic local service to customers within a local exchange carrier's service
      area,

    - network access services to interexchange carriers for origination and
      termination of interstate and intrastate long distance phone calls,

    - enhanced services, such as call waiting, call forwarding, caller ID and
      voice mail and

    - other services, such as billing and collection, directory publishing,
      directory assistance and Centrex, a switch-based service offering for
      business customers.

Rural local exchange carriers typically receive the majority of their revenues
from access charges, as opposed to the regional Bell operating companies, which
receive a greater share of revenues from basic local services.

    The characteristics of a rural local exchange carrier's service areas result
in higher costs for the local exchange carrier because of the additional costs
of providing the infrastructure to rural customers and the lack of economies of
scale available in more densely populated areas. To ensure that affordable
universal telephone service is available in remote areas, rural local exchange
carriers typically benefit from various support mechanisms. The largest explicit
support mechanism for rural local exchange carriers are universal service
payments, as more fully described under "Regulation".

ALASKA OVERVIEW

    The population of Alaska was approximately 614,000 at June 30, 1998, having
grown at a compound annual rate of 1.3% over the past ten years, compared to
1.0% for the U.S. as a whole. While the majority of the population is
concentrated in the city of Anchorage and surrounding areas, population growth
in recent years has been broadly distributed throughout the state. The U.S.
Census Bureau projects that through 2005 the population of Alaska will grow at a
compound annual rate of 1.9%, as compared to 0.8% for the U.S. as a whole,
through 2005.

    Alaska has the highest median household income in the U.S. According to the
U.S. Census Bureau, Alaska's average median household income during the period
from 1995 to 1997 was $50,829, approximately 40% greater than the overall U.S.
median household income. Alaskans benefit from the absence of state personal
income taxes and receive annual per capita payments from the Alaska Permanent
Fund which in 1999 totaled over $1,700 per person.

    Historically, the state's economy has depended significantly on natural
resource industries in general and the petroleum industry in particular. In
1996, the most recent year for which the gross state product was calculated, the
petroleum industry represented approximately 36.3% of the $25.9 billion gross
state product. In 1998, most of the employment growth in Alaska was attributable
to the services sector and, in particular, health care, hotels and social
services.

                                    BUSINESS

    We are the leading diversified, facilities-based telecommunications provider
in Alaska, offering local telephone, wireless, long distance, data and Internet
services to business and residential customers throughout the state. We are the
only telecommunications provider in Alaska using its own network facilities to
provide end-to-end communications services to its customers.

    LOCAL TELEPHONE.  With over 320,000 access lines, representing 75% of the
access lines in Alaska, we are the largest local exchange carrier in Alaska and
the 15th largest in the U.S. We provide service to all of the state's major
population centers, including Anchorage, Juneau and Fairbanks. There are no
regional Bell operating companies in Alaska.

    WIRELESS.  We are the largest and only statewide provider of wireless
services in Alaska, currently serving over 70,000 subscribers. Our wireless
network covers over 460,000 residents, including all major population centers
and highway corridors. We are in the process of upgrading our network to be
fully digital in all of our service areas by year-end 1999.

    LONG DISTANCE.  We provide long distance and other interexchange services to
approximately 26,000 customers primarily in Anchorage and intend to market these
services statewide beginning in the first quarter of 2000. We recently migrated
long distance traffic from leased circuits onto our own network infrastructure,
which we believe will result in significant cost savings over time.

    DATA AND INTERNET.  We are the third largest provider of Internet access
services in Alaska with approximately 16,000 customers. We also own 28.5% of the
second largest Internet services provider in Alaska with approximately 28,000
customers. We currently offer dedicated and dial-up Internet access to our
customers and intend to offer digital subscriber line, or DSL, services by
year-end 1999.


    In addition, we recently acquired a majority interest in Alaskan Choice
Television, a provider of cable television services in our Fairbanks and
Anchorage service areas, and expect to expand our offering of wireless cable
services using digital compression technology.


    Our telecommunications network includes over 485 miles of fiber optic cable,
176 switching facilities and a statewide cellular network. In addition, we
recently purchased fiber capacity for high speed links within Alaska and for
termination of traffic in the lower 48 states. We plan to continue enhancing our
network to meet customer demand for increased bandwidth and advanced services.

    For the year ended December 31, 1998, on a pro forma basis, we would have
had combined revenues of $281.6 million, operating income of $40.6 million,
Adjusted EBITDA, as defined under "Summary Unaudited Pro Forma Combined
Financial and Operating Data", of $106.1 million and a net loss of
$17.3 million.


    We were formed in 1998 by Fox Paine & Company, members of the former senior
management team of Pacific Telecom, and other experienced telecommunications
industry executives. In May 1999, we acquired Century's Alaska properties and
ATU. Century's Alaska properties were the incumbent provider of local telephone
services in Juneau, Fairbanks and more than 70 rural communities in Alaska and
provided Internet services to customers statewide. ATU was the largest local
exchange carrier in Alaska and provided local telephone and long distance
services primarily in Anchorage and cellular services statewide. On October 28,
1999, we changed our name from ALEC Holdings, Inc. to Alaska Communications
Systems Group, Inc.


OUR BUSINESS OPPORTUNITY

    Alaska is characterized by its large geographic size, widely dispersed
population and large distance between urban areas. Over 60% of the state's
population resides in its three largest cities:

                                       59
<PAGE>
Anchorage, Juneau and Fairbanks. Alaska lacks an effective ground transportation
infrastructure, and many of the state's communities are accessible only by air
or water. As a result, Alaskans are particularly dependent on telecommunications
services to access resources and information unavailable in their communities.
We estimate that Alaskan telecommunications businesses generated aggregate
revenues of $1 billion in 1998.

    Alaska's income and demographic characteristics provide opportunities for
continued growth of telecommunications services. Alaska has the highest median
household income in the U.S. In addition, Alaskans pay no state personal income
taxes and receive an annual per capita payment from the Alaska Permanent Fund.
The population in Alaska has been growing at a compound annual rate of 1.3% over
the last ten years, compared to 1.0% for the U.S. as a whole. The U.S. Census
Bureau projects that Alaska's population will grow at a compound annual rate of
1.9%, as compared to 0.8% for the U.S. as a whole, through 2005.

    We believe that the outlook for growth in our businesses is favorable due to
the fundamental demand for telecommunications, including:

    - continued demand for core telephone services and enhanced service
      offerings, such as voice mail and call waiting,

    - access line growth due to population growth and the demand for multiple
      lines,

    - increasing demand for wireless services and

    - DSL and Internet access growth due to higher business and consumer
      bandwidth needs for data and Internet services.

OUR BUSINESS STRATEGY

    As part of our business strategy, we intend to:

    LEVERAGE OUR NETWORK AND CUSTOMER BASE.  As the leading diversified,
facilities-based telecommunications provider in Alaska offering customers a
broad array of services over our extensive network, we believe we have a
significant competitive advantage. Our competitive position provides us with a
valuable opportunity to capitalize on the growing demand for communications
services and the development of new technologies and services. In particular, we
intend to:

        PROVIDE ONE-STOP COMMUNICATIONS SERVICES.  We intend to offer a complete
    suite of telecommunications and data services, providing both residential
    and business customers with local telephone, long distance and wireless, as
    well as high speed data and Internet services. We also intend to introduce
    new telecommunications products and services as they develop. We believe
    that providing one-stop communications services will enable us to meet our
    customers' increasingly complex communications needs and to strengthen our
    position by capturing a larger portion of our customers' communications
    expenditures.

        INCREASE PENETRATION OF ENHANCED SERVICES.  We seek to achieve a higher
    penetration of enhanced services among our significant base of installed
    customers. Customer penetration of enhanced services such as call waiting,
    caller ID and voice mail, calculated as the number of enhanced services
    divided by the number of access lines, in our service areas is approximately
    86%, while other local exchange carriers in the U.S. have achieved average
    penetration levels of 121%. We believe we can achieve penetration rates for
    these services comparable to these industry averages. Increasing our
    penetration rates will improve our revenue per customer which we expect, due
    to the fixed cost nature of our local exchange business, to result in
    improved operating margins.

                                       60
<PAGE>
        OFFER COMPLEMENTARY COMMUNICATIONS AND MEDIA SERVICES.  We intend to
    expand our service offerings with a particular focus on data, Internet and
    wireless cable television services. We anticipate significant demand for
    these services as they become necessary for businesses and increasingly
    desirable for residential users. We currently offer ISDN and other
    high-speed data services and intend to introduce DSL services by year-end
    1999. During 2000, we intend to expand our service offerings to include
    virtual private networks, statewide Centrex services, such as four digit
    dialing, and enhanced digital wireless cable television services.

    PROVIDE SUPERIOR CUSTOMER SERVICE.  We are committed to building strong
customer relationships by providing high-quality customer care. We believe that
by increasing customer loyalty and retention we will enhance our ability to
market our service offerings. We are building a state-of-the-art customer care
system that will provide one-call customer service access, improved call
response times and, we believe, greater overall customer satisfaction. In
addition, we will provide web-based services that will allow customers to check
billing, order new services or otherwise manage their accounts online.

    BUILD THE LEADING COMMUNICATIONS BRAND IN ALASKA.  We intend to take
advantage of our statewide presence and centralized marketing efforts by
promoting a unified brand name. We intend to, over time, transition our entire
suite of telecommunications services to be marketed under the "Alaska
Communications Systems" brand, which we seek to make synonymous with high-
quality telecommunications. We believe that a single brand uniting all of our
service offerings will result in superior brand awareness, greater product
penetration and higher demand for packages of premium-priced branded services.

    REALIZE OPERATING EFFICIENCIES.  We seek to realize significant operating
efficiencies from the consolidation and integration of our recent acquisitions
and the continuous improvement of our operations. We believe we will realize
significant future savings by consolidating Century's Alaska properties and ATU
into a single operating entity, subject to regulatory restrictions. We intend to
continue to make investments in information technology relating to service
provisioning, network management and customer service which we believe will
improve operating margins. In addition, we are creating an integrated low cost
network utilizing state-of-the-art technology which we believe will further
improve operating margins.

    PURSUE SELECTED STRATEGIC ACQUISITIONS.  We are actively pursuing selected
regional acquisitions in Alaska. There are 19 local exchange carriers remaining
in Alaska with an aggregate of approximately 120,000 access lines, presenting us
with the potential for significant expansion of our network. In addition, we may
pursue other selected strategic acquisitions and investments which will
complement our existing product and service offerings.

PRODUCTS, SERVICES AND REVENUE SOURCES

    We offer a broad portfolio of telecommunications services to residential and
business customers in our markets. Our service offerings are locally managed to
better serve the needs of each community. We believe that, as the communications
marketplace continues to converge, our ability to offer an integrated package of
communications products will provide a distinct competitive advantage, as well
as increase customer loyalty, thereby decreasing customer turnover. We intend to
complement our local telephone services by actively marketing our wireless, long
distance, data and Internet service offerings.

    LOCAL TELEPHONE SERVICES

    BASIC LOCAL SERVICE.  Basic local service enables customers to originate and
receive telephone calls within a defined "exchange" area. We provide basic local
services to residential and business customers, generally for a fixed monthly
charge. The maximum amount that we can charge a customer for basic local
services is determined by rate proceedings involving the RCA. We charge business
customers higher rates to recover a portion of the costs of providing local
service to residential customers. On average, U.S. business rates for basic
local services have been over two times the rates of residential customers.
Basic local service also includes non-recurring charges to customers for the
installation of new products and services.

    At December 31, 1998, approximately 60% of our retail access lines served
residential customers, while 40% served business customers. Currently, our
monthly charges for basic local service for residential customers range from
$9.42 to $16.30 in the service areas of Century's Alaska properties and are
$9.70 in ATU's service area, as compared to the national average of $15.99.
Monthly charges for business customers range from $17.65 to $26.05 in the
service areas of Century's Alaska properties and are $25.75 in ATU's service
areas, as compared to the national average of $34.55.

    The table below sets forth the growth in access lines at Century's Alaska
properties and ATU from December 31, 1994 to December 31, 1998 and for the six
month period ended June 30, 1999. The number of access lines shown for Century's
Alaska properties in 1997 includes approximately 37,000 access lines that were
acquired by Century's Alaska properties as part of its acquisition of the City
of Fairbanks Telephone Operation in October 1997. The number of access lines
shown for ATU represents all revenue producing access lines connected to retail
or wholesale customers.

</TABLE>



On June 1, 1999, as part of the consolidation of our operating and billing
systems, we conformed the methodology by which we calculate our number of access
lines across all of our local exchanges to that used for Century's Alaska
properties. We intend to use the method used to calculate access lines in
service for Century's Alaska properties to calculate our access lines in all
future periods. In the table above, for the period ended September 30, 1999, we
show ATU's number of access lines calculated using this method. If we computed
the number of ATU's access lines in service at December 31, 1998 under this same
method, the number of access lines at ATU would increase by 4,940 and the total
number of access lines would equal 305,334. Due to limited data available to us,
we have not computed any adjustments to the access lines in service for any year
prior to 1998.


    Future growth in access lines is expected to be derived from:

    - increases in line demand from data-related usage by existing business
      customers,

    - increased additional line demand from Internet usage by residential
      customers and

    - population growth in our service areas.

    ENHANCED SERVICES.  Enhanced services consist of services such as call
waiting, call forwarding, call return, continuous redial, caller ID and voice
mail. These services are generally billed on a monthly basis together with the
customers' bills for basic local services. Customer penetration of enhanced
services, calculated as the number of enhanced services divided by the number of
access lines, in our service areas is approximately 86%, while other rural local
exchange carriers in the U.S. have achieved a penetration level of 121%, on
average.

    NETWORK ACCESS

    Network access services arise in connection with the origination and
termination of long distance, or toll, calls and typically involve more than one
company in the provision of such long distance service on an end-to-end basis.
Since toll calls are generally billed to the customer originating the call, a
mechanism is required to compensate each company providing services relating to
the call. This mechanism is the access charge, which we bill to each
interexchange carrier for the use of our facilities to access the customer, as
described below.

                                       63
<PAGE>
    INTRASTATE ACCESS CHARGES.  We generate intrastate access revenue when an
intrastate long distance call which involves an interexchange carrier is
originated and terminated within the same state. The interexchange carrier pays
us an intrastate access payment for either terminating or originating the call.
We record the details of the call through our carrier access billing system and
receive the access payment from the interexchange carrier. When one of our
customers originates the call, we typically provide billing and collection for
the interexchange carrier through a billing and collection agreement. The access
charge for our intrastate service is regulated by the RCA.

    INTERSTATE ACCESS CHARGES.  We generate interstate access revenue when an
interstate long distance call is originated from a local calling area in one
state to a local calling area in another state. We bill interstate access
charges in the same manner as we bill intrastate access charges; however, the
interstate access charge is regulated by the FCC rather than by the RCA.

    WIRELESS SERVICES

    Our cellular businesses currently are managed separately from our local
exchange carrier business and are subject to a different regulatory framework
and cost structure. ATU's wireless services are provided statewide under the
MACtel brand name. Management intends to integrate Century's Alaska properties'
cellular operations with those of MACtel. The primary sources of wireless
revenue include subscriber access charges, airtime usage, toll charges,
connection fees, roaming revenues, as well as enhanced features, such as voice
mail. A subscriber may purchase services separately or may purchase rate plans
that package these services in different ways to fit different calling patterns.
We currently provide digital service in Anchorage and Fairbanks and expect to be
fully digital in our other service areas by the end of 1999. Upon conversion to
digital service, we will be able to offer advanced digital services and
features, such as text messaging.

    As illustrated in the table below, Century's Alaska properties and MACtel
have experienced growth in the number of cellular subscribers served and total
covered population over the past five years.

    Although we have achieved cellular penetration rates of 18% and 19% in
Anchorage and Kenai, penetration rates in our other service areas are
significantly lower. Management believes there are opportunities to improve the
penetration rates of our cellular operations in Fairbanks and Juneau. Management
also believes that the market for wireless services will continue to grow with
the growth in the wireless industry as a whole.

                                       64
<PAGE>
    We also own 10 megahertz E Block PCS licenses covering Anchorage, Juneau and
Fairbanks, which were purchased by Century's Alaska properties in 1997.
Management is analyzing the build out of these licenses and technical
alternatives for using this spectrum to enhance our service offerings in our
overall business.

    LONG DISTANCE SERVICES

    We began offering long distance services on a resale basis in October 1997,
primarily in Anchorage. We currently have approximately 26,000 long distance
customers and less than 2.5% of total long distance revenues in Alaska. We
intend to expand our long distance operations into the service areas of
Century's Alaska properties during the first quarter of 2000. Before
August 1998, Century's Alaska properties were precluded from entering the long
distance business by a non-competition agreement with AT&T Alascom which was
signed when Pacific Telecom sold Alascom, Inc. to AT&T in 1995. To date, our
long distance operations have generated operating losses.

    In April 1999, we entered into a settlement agreement with GCI under which
we agreed to enter into a number of new business arrangements and to settle a
number of outstanding disputes, including GCI's opposition to our acquisitions
of Century's Alaska properties and ATU, the effect of which is not expected to
be material. As part of this agreement and to reduce our dependence on a resale
long distance strategy, we purchased from GCI $19.5 million of fiber capacity
for high speed links within Alaska and for termination of traffic in the lower
48 states. Subsequently, we entered into an amendment of our purchase agreement
with GCI, whereby, among other things, we agreed to purchase additional capacity
in 2001 for $19.5 million. We expect that migrating long distance traffic onto
our network facilities will over time reduce the cost of providing long distance
and other interexchange services and data and Internet access services.

    We are subject to numerous conditions imposed by the RCA and, to a lesser
degree, by the FCC on the manner in which we conduct our long distance
operations. The restrictions are intended to prohibit cross-subsidization from
the regulated local exchange carrier to the unregulated long distance affiliate
and discrimination against other long distance providers in favor of a local
exchange carrier's long distance affiliate. Among the conditions applied to our
long distance affiliates are those which:

    - require us to hold all books and records, management, employees and
      administrative services separate, except that services may be provided
      among affiliates through arms-length affiliated interest agreements,

    - prohibit Century's Alaska properties from bundling local and long distance
      services until competition develops in their local markets and

    - prevent us from joint ownership of telephone transmission or switching
      facilities with the local exchange carrier and from using the local
      exchange carrier's assets as collateral for its own indebtedness.

    As a result of the introduction of competition in ATU's local service areas,
the APUC lifted the restriction on bundling on local and long distance services
in ATU's service areas in 1998.

    INTERNET ACCESS

    We provide Internet access services to approximately 16,000 customers and
generated $5.1 million in Internet access revenues for the year ended
December 31, 1998. In order to offer Internet access, we provide local dial-up
telephone numbers for our customers. These local dial-up numbers allow customers
access, through a modem connection on their computer, to a series of computer
servers we own and maintain. These servers allow customers to access their
e-mail

                                       65
<PAGE>
accounts and to be routed to local access points that connect customers to the
Internet. We charge customers either a flat rate for unlimited Internet usage or
a usage sensitive rate, which, in either case, is billed in conjunction with the
local telephone bill.

    We also own a 28.5% minority interest in Internet Alaska, Inc., which
provides Internet access to approximately 28,000 customers primarily in
Anchorage and Fairbanks.

    WIRELESS CABLE TELEVISION


    We own a two-thirds interest in Alaskan Choice Television, a wireless cable
television provider, having recently acquired the previous managing member's
one-third interest. Alaskan Choice Television provides wireless cable television
services over assigned UHF frequencies to approximately 3,000 customers in our
Anchorage and Fairbanks service areas. We have reached agreement to acquire the
remaining one-third interest and expect that transaction to be completed before
year-end 1999.


    UNIVERSAL SERVICE REVENUE

    Universal service revenue supplements the amount of local service revenue we
receive to ensure that basic local service rates for customers in high cost
rural areas are not significantly higher than rates charged in lower cost urban
and suburban areas. The Telecommunications Act prescribed new standards
applicable to universal service, including mechanisms for defining the types of
services to be provided as part of a universal service program, specific goals
or criteria applicable to universal service programs, new qualifications for
receipt of universal service funding and new requirements for contributions to
universal service funding. The FCC, in conjunction with a federal-state joint
board composed of FCC and state commission members, has been working since
passage of the Telecommunications Act to implement these new statutory
provisions. The FCC has chosen to address universal service matters, initially
for non-rural telephone companies, and subsequently for rural telephone
companies. New cost-identification models for non-rural local carriers are
presently expected to be implemented on January 1, 2000 and would be applicable
to our ATU operations. New rules for rural telephone companies, applicable to
Century's Alaska properties, are not expected to be adopted before January 1,
2001 at the earliest.

    OTHER

    We seek to capitalize on our local presence and network infrastructure by
offering additional services to customers, such as directory services and
billing and collection services for interexchange carriers.

NETWORK FACILITIES


    As of September 30, 1999, we owned 74 exchanges serving over 320,000 access
lines. All of our exchanges are served by digital switches provided
predominately by Nortel Networks. Our switches are linked through a combination
of extensive aerial, underground and buried cable, including 485 miles of fiber
optic cable, as well as digital microwave and satellite links. We have 100%
single-party services (one customer per access line), and believe all switches
have the latest generic software upgrades available, allowing for the full range
of enhanced customer features.


    We have integrated numerous network elements to offer a variety of services
and applications that meet the increasingly sophisticated needs of customers.
These elements include Signal System 7 signaling networks, voice messaging
platforms, digital switching and, in some communities, integrated service
digital network access. As the telecommunications industry experiences
significant changes in technology, customer demand and competitive pressures, we
intend to introduce additional enhancements.

                                       66
<PAGE>
    Network operations and monitoring are provided for Century's Alaska
properties and ATU by ATU's network operating control center located in
Anchorage. The network operating control center has technicians staffed or
on-call seven days a week, 24 hours a day. Automated alarm systems are in place
should problems arise with the network after normal business hours. We also have
customer care facilities in Anchorage and Fairbanks with extensive business
hours to efficiently handle customer inquiries and orders for service.

    Our cellular operations consist of eight switching centers and 77 cell sites
covering all major population centers and highway corridors in Alaska. We plan
to complete the conversion of all of our switching and cell site equipment to
digital service by the end of 1999. Our switching and cell site infrastructure
is linked by digital microwave and fiber. MACtel also has a network operating
control center and customer care center, located in Anchorage.

    We are enhancing our interexchange network to accommodate developing
products and technology. We are working with Nortel Networks on a multiple phase
conversion of our network from a time division multiple access, or TDMA, circuit
switched platform to an asynchronous transfer mode/Internet protocol, or ATM/IP,
packet switched platform based on Nortel's SUCCESSION NETWORK-TM-. We believe
the implementation of the SUCCESSION NETWORK-TM- will enable us to provide a
complete suite of telecommunications and data services and achieve significant
operating efficiencies. We have completed the first phase of the conversion,
which resulted in the migration of our network traffic to our fiber optic
transport facilities acquired in June 1999. We are currently in the second
phase, which will involve the conversion of our transport connections between
Anchorage and each of Fairbanks, Kenai, Juneau and Seattle from TDMA to ATM,
which we expect to complete by year-end 1999. We expect to complete the
implementation of Nortel's SUCCESSION NETWORK-TM- by year-end 2002. Our planned
network enhancements prior to year-end 2002 will include the installation of
call servers in Anchorage and either Fairbanks or Juneau and the conversion of
network switching nodes to accommodate ATM/IP traffic.

    Completion of the SUCCESSION NETWORK-TM- will enable us to provide an array
of IP products throughout our core business. We currently offer frame relay, and
will offer each of the following services as the necessary network elements are
completed:

    - virtual private networks,

    - virtual private lines,

    - transparent local area networks (LAN),

    - proprietary LANs and wide area networks (WAN) and

    - high speed Internet access.

COMPETITION

    LOCAL TELEPHONE SERVICES

    Incumbent local exchange carriers may be subject to any of three types of
competition:

    - facilities-based competition from providers with their own local service
      network,

    - resale competition from resale interconnection, or providers who purchase
      local service from the incumbent local exchange carrier at wholesale rates
      and resell these services to their customers and

    - competition from unbundled network element interconnection, that is,
      providers who lease unbundled network elements from the incumbent local
      exchange carrier.

    The geographic characteristics of rural areas make the entrance of most
facilities-based competitors uneconomical because of the significant capital
investment required and the limited market size. Thus, competition is likely to
come from resale interconnection or unbundled network element interconnection.
There are no regional Bell operating companies in Alaska.


    In September 1997, GCI and AT&T Alascom, the two largest long distance
carriers in Alaska, began providing competitive local telephone services in
Anchorage. GCI competes principally through unbundled network element
interconnection with ATU's facilities, while AT&T Alascom competes exclusively
by reselling ATU's services. Competition is based upon price and pricing plans,
types of services offered, customer service, billing services, quality and
reliability. GCI has focused principally on advertising discount plans for
bundled services. AT&T Alascom's strategy has been to resell ATU's service as
part of a package of local and long distance services. As a result, ATU lost
approximately 19% of its retail access lines in Anchorage to these competitors
during the first ten months of competition ended June 1998, approximately 61% of
which resulted from unbundled network element interconnection by GCI. The
majority of this loss was among price-sensitive residential customers who have
lower average monthly bills than ATU's business customers. Since June 1998, the
rate of this loss has slowed, with ATU's aggregate market share loss rising only
from 19% to just over 23% in the last fifteen months. We expect GCI and AT&T
Alascom to continue to compete for local telephone business.



    As "rural telephone companies" under the Telecommunications Act, our rural
local exchange carriers have historically been exempt from the obligation to
lease their facilities or resell their services on a wholesale discount basis to
competitive local exchange carriers seeking interconnection. However, on
June 30, 1999 the APUC ordered these exemptions terminated, and on October 11,
1999, the RCA, which replaced the APUC on July 1, 1999, sustained the APUC's
order. As a result, we may be required to provide interconnection elements
and/or wholesale discount services to competitors in some or all of our rural
service areas. However, we believe that our services offerings, customer
relationships and expertise in the local telephone business may provide us a
competitive advantage over new local exchange carriers.


    We expect increasing competition from providers of various services that
provide users the means to bypass our network. Long distance companies may
construct, modify or lease facilities to transmit traffic directly from a user
to a long distance company. Cable television companies, in particular, may be
able to modify their networks to partially or completely bypass our local
network.

    In addition, while cellular telephone services have historically
complemented traditional local exchange carrier services, we anticipate that
existing and emerging wireless technologies may increasingly compete with local
exchange carrier services. Technological developments in cellular telephone
features, personal communications services, digital microwave and other wireless
technologies are expected to further permit the development of alternatives to
traditional landline services.

                                       68
<PAGE>
    WIRELESS SERVICES

    The wireless telecommunications industry is experiencing significant
technological change, as evidenced by the increasing pace of improvements in the
capacity and quality of digital technology, shorter cycles for new products and
enhancements and changes in consumer preferences and expectations. We believe
that the demand for wireless telecommunications services is likely to increase
significantly as equipment costs and service rates continue to decline and
equipment becomes more convenient and functional. We currently compete with at
least one other cellular provider in each of our wireless service areas,
including AT&T Wireless Services, Century and Mercury Communications.
Competition is based on price, quality, network coverage and brand reputation.
In addition, there are six PCS licensees in each of our wireless service areas.
We hold PCS licenses covering Anchorage, Fairbanks and Juneau. One of the PCS
licensees began providing digital PCS service in Anchorage in October 1998.
Another PCS licensee has recently indicated it will commence trials of its
technology. We believe that the unique and vast terrain and the high cost of PCS
system buildout makes entrance into markets outside Anchorage unlikely.

    LONG DISTANCE SERVICES

    The long distance telecommunications market is highly competitive.
Competition in the long distance business is based on price, customer service,
billing services and quality. We currently offer long distance in ATU's service
areas, and intend, subject to regulatory restrictions, to expand ATU's long
distance operations into the service areas of Century's Alaska properties. AT&T
Alascom and GCI are currently the two major long distance providers in Alaska,
including in our service areas. We currently have less than 2.5% of total long
distance revenues in Alaska.

    INTERNET SERVICES

    The market for Internet access services is highly competitive. There are few
significant barriers to entry, and we expect that competition will intensify in
the future. We currently compete with a number of established online services
companies, interexchange carriers and cable companies. We believe that our
ability to compete successfully will depend upon a number of factors, including
the reliability and security of our network infrastructure, the ease of access
to the Internet and the pricing policies of our competitors.

CUSTOMERS

    We have two basic types of customers for our local services:

    - business and residential customers located in their local service areas
      that pay for local phone service and

    - interexchange carriers that pay us for access to long distance calling
      customers located within our local service areas.

In general, the majority of our local customers are residential, rather than
business, customers, as is typical for rural telephone companies. In addition,
no single local customer of ours represented more than 5% of our total 1998 pro
forma revenue, excluding access customers.

SALES AND MARKETING

    Century's Alaska properties and ATU have historically conducted their sales
and marketing operations for each of their respective products on a stand-alone
basis, with each product line having its own sales force and marketing
department. Going forward, we intend to consolidate our product and service
offerings under the "Alaska Communications Systems" brand, subject to regulatory
and strategic business considerations.

                                       69
<PAGE>
    Key components of our sales and marketing strategy include:

    - marketing current and future service offerings aggressively, including
      packaged service offerings,

    - centralizing marketing functions and

    - enhancing direct sales efforts.

    We believe that we can leverage our position as an integrated, one-stop
provider of telecommunications services with strong positions in local access,
wireless, long distance and data and Internet markets. By pursuing a marketing
strategy that takes advantage of these characteristics and that facilitates
cross-selling and packaging of our products and services, we believe we can
increase penetration of new product offerings, improve customer retention rates,
increase our share of our customers' overall telecommunications expenditures and
achieve continued revenue and operating cash flow growth.

    While Century's Alaska properties and ATU have, to a limited extent,
marketed local telephone services in attractively-priced, packaged service
offerings with wireless, long distance and Internet services, neither Century's
Alaska properties nor ATU emphasized these types of offerings. However, we
believe packaged offerings are popular with customers because they allow
customers to enjoy pricing for a number of services at a substantial discount to
A LA CARTE pricing of individual services. Subject to regulatory limitations, we
intend to expand this strategy, which we expect will increase the average
revenue per customer and result in a more loyal and satisfied customer base and
reduced churn.

    We have established a sales and marketing organization where marketing
strategies will be centralized and sales functions will be based locally. To
enhance our direct selling efforts, we have established additional customer and
retail service centers in our larger service areas, such as Juneau and
Kenai/Soldotna, and intend to enhance call center operations through a
combination of technology investments and training and incentive compensation
programs for call center employees.

SUPPLIERS

    We believe we have strong, long-term relationships with our numerous
communications vendors. Our primary switching vendor is Nortel Networks, a
leading provider of advanced switching systems. We use Ericsson switches and
radios for our cellular operations. For our billing systems we use Saville
Systems, and for our accounting systems we use SAP. Our primary information
technology architecture is provided by IBM. While we recognize that the
separation of Century's Alaska properties from the rest of Century's properties
might result in higher unit costs for Century's Alaska properties, we expect
that the combination of Century's Alaska properties and ATU and the presence of
vendor competition will deter any significant unit increases and may result in
unit cost reductions in the longer term. We enjoy positive relationships with a
variety of vendors for outside plant facilities and other elements of our
network.

EMPLOYEES


    We consider employee relations to be good. As of September 30, 1999, we
employed a total of 1,187 regular full-time employees, 791 of whom were
represented by unions.



    Century's Alaska properties have a collective bargaining agreement with the
IBEW that expires in 2004. This agreement provides for wage increases up to 4%
based upon the annual increases in the U.S. Department of Labor CPI-U, the
Consumer Price Index for Anchorage. ATU also has a contract with the IBEW that
was scheduled to expire in August 1999. Management believes that negotiations
with the IBEW regarding the terms under which ATU's represented employees would


                                       70
<PAGE>

be transitioned to Century's Alaska properties' collective bargaining agreement
are substantially concluded. We believe these terms will be ratified by the IBEW
membership and the transition completed prior to November 30, 1999. A
ratification vote by the IBEW membership is scheduled for November 2, 1999.
ATU's existing agreement remains in full force and effect pending conclusion of
the negotiation and ratification process, and we are confident that a mutually
acceptable transition can be effected with the IBEW. There have been no work
stoppages or strikes by either Century's Alaska properties' or ATU's employees,
and management has worked closely with IBEW leadership for many years.


ENVIRONMENTAL REGULATIONS

    Our operations are subject to federal, state and local laws and regulations
governing the use, storage, disposal of, and exposure to, hazardous materials,
the release of pollutants into the environment and the remediation of
contamination. As an owner or operator of property and a generator of hazardous
wastes, we could be subject to environmental laws that impose liability for the
entire cost of cleanup at contaminated sites, regardless of fault or the
lawfulness of the activity that resulted in contamination. We believe, however,
that our operations are in substantial compliance with applicable environmental
laws and regulations.

    Many of our properties formerly contained, or currently contain, underground
and aboveground storage tanks used for the storage of fuel or wastes. Some of
these tanks have leaked. We believe that known contamination caused by these
leaks has been, or is being, investigated or remediated. We cannot be sure,
however, that we have discovered all contamination or that the regulatory
authorities will not request additional remediation at sites that have
previously undergone remediation.

    Our cellular operations are also subject to regulations and guidelines that
impose a variety of operational requirements relating to radio frequency
emissions. The potential connection between radio frequency emissions and
negative health effects, including some forms of cancer, has been the subject of
substantial study by the scientific community in recent years. To date, the
results of these studies have been inconclusive. Although we have not been named
in any lawsuits alleging damages from radio frequency emissions, it is possible
we could be sued in the future, particularly if scientific studies conclusively
determine that radio frequency emissions are harmful.

PROPERTIES

    LOCAL TELEPHONE.  Our primary properties consist of 168 switching facilities
serving 74 exchanges. We own most of our administrative and maintenance
facilities, central office and remote switching platforms and transport and
distribution network facilities. We lease our corporate headquarters located in
Anchorage.

    Our transport and distribution network facilities include a fiber optic
backbone and copper wire distribution facilities that connect customers to
remote switch locations or to the central office and to points of presence or
interconnection with interexchange carriers. These facilities are located on
land pursuant to permits, easements or other agreements.

    WIRELESS.  We have 77 cell sites that cover all major population centers and
highway corridors throughout Alaska. In most cases, we lease the land on which
these sites are located.

LEGAL PROCEEDINGS

    We currently, and from time to time, are involved in litigation and
regulatory proceedings incidental to the conduct of our business. Some of these
regulatory proceedings are described under "Risk Factors" and "Regulation". We
are not a party to any lawsuit or proceeding that, in the opinion of management,
is likely to have a material adverse effect on us.

<PAGE>
                                   REGULATION

OVERVIEW


    Our operations are subject to the separate but concurrent jurisdictional
control of both the federal government and the State of Alaska. Our local
telephone operating subsidiaries, Telephone Utilities of the Northland,
Telephone Utilities of Alaska and PTI Communications, which was formerly the
City of Fairbanks Telephone Operation, and ATU are each "telecommunications
carriers" and "local exchange carriers" under the Communications Act of 1934,
which was amended by the Telecommunications Act, and are subject to FCC
jurisdiction as are our wireless communications activities. Our local telephone
operating companies are also "public utilities" within the meaning of the Alaska
statutes and are, therefore, governed by the applicable rules and regulations of
the RCA. The RCA succeeded to the regulatory responsibilities of the APUC when
it ceased to exist on June 30, 1999. Only one of the new RCA commissioners has
prior APUC experience.


FEDERAL REGULATION


    Under the federal regulatory scheme, incumbent local exchange carriers are
required to comply with the Communications Act and the applicable rules and
regulations of the FCC. In substantially overhauling the Communications Act, the
Telecommunications Act was intended to, among other things, eliminate
unproductive regulatory burdens and promote competition. Despite this,
telecommunications carriers are still subject to extensive ongoing regulatory
requirements. For instance, FCC-regulated entities, like our subsidiaries, are
required to maintain accounting records in accordance with the Uniform System of
Accounts to structure access charges according to FCC rules, and to reflect in
their charges for interstate services at a rate of return prescribed by the FCC.
The FCC also regulates transfers of control and assignments of these operating
authorizations and construction licenses. The FCC requires carriers providing
access services to file tariffs with the FCC reflecting the rates, terms and
conditions of those services. These tariffs are subject to review and potential
objection by the FCC or third parties. Additionally, all of our local exchange
carriers are "incumbent local exchange carriers" within the meaning of the
Telecommunications Act. As such, they are subject to various requirements under
that Act, including specific interconnection duties such as the provisioning of
unbundled network elements and of wholesale discounted resale of end user
services.


STATE REGULATION


    Telecommunications companies subject to the RCA's jurisdiction are required
to obtain certificates of public convenience and necessity prior to operating as
a public utility in Alaska. The RCA is responsible for approving new issuances
and any transfers of these operating certificates. In addition, the RCA is
responsible for implementing a portion of the competitive requirements of the
Telecommunications Act, as well as for regulating intrastate access and local
service rates and services of local telephone companies. After passage of the
Telecommunications Act, the APUC adopted a plan to address competition issues
across Alaska. The APUC established multiple dockets to investigate different
competition-related issues, including revising local and long distance market
structures, reforming its intrastate access charge system and establishing a
state universal service fund. While some of these dockets have been completed,
many others remain open for further processing by the RCA. In connection with
regulatory approval of our acquisitions of Century's Alaska properties and ATU,
the APUC imposed several conditions on our operating companies. Among those
conditions was a requirement that ATU, PTI Communications of Alaska, Inc.,
Telephone Utilities of Alaska, Inc. and Telephone Utilities of the Northland,
Inc. each file revenue requirement, cost of service and rate design studies no
later than July 2001. Additionally,


                                       72
<PAGE>

restrictions were placed on the ability of our rural local exchange carriers to
bundle service offerings with ATU Long Distance, Inc.


COST RECOVERY AND REVENUE RECOGNITION

    As a regulated common carrier, we are afforded the opportunity to set
maximum rates at a level that allows us the opportunity to recover the
reasonable costs we incur in the provision of regulated telecommunications
services and to earn a reasonable rate of return on the investment required to
provide these services.

    These costs are recovered through:

    - monthly charges to end users for basic local telephone services and
      enhanced service offerings,

    - access charges to interexchange carriers for originating and terminating
      interstate and intrastate interexchange calls,

    - interconnection charges, wholesale service charges and other rates to
      competing carriers interconnecting with our networks or reselling our
      services and

    - high-cost support mechanisms, such as the federal Universal Service Fund
      and the Alaska Universal Service Fund.

Rates for regulated services, and the amount of high-cost support, are set by
the FCC with respect to interstate services and by the RCA with respect to
intrastate services.

    In conjunction with the recovery of costs and establishment of rates, a
local exchange carrier must first determine its aggregate costs and then
allocate those costs between regulated and nonregulated services.

    After identifying the regulated costs of providing local telephone service,
a local exchange carrier must allocate those costs among its various local
exchange and interstate and intrastate interexchange services and between state
and federal jurisdictions. This process is complicated by the difficulty of
allocating specific pieces of plant and equipment to a particular service
because a local exchange carrier's plant and equipment are utilized for
different services, such as local telephone and interstate and intrastate
access. This process is referred to as "separations" and is governed primarily
by the FCC's rules and regulations. The underlying legal purpose of separations
rules is to define how a carrier's expenses are allocated and recovered from
federal and state jurisdictions. The FCC is considering whether to modify or
eliminate the current separations process. This decision could indirectly
increase or reduce earnings of carriers subject to separations rules.

    INTERSTATE END-USER RATES


    The deployment of the local telephone network from the switching facility to
the customer is known as the "local loop" and is one of the most significant
costs incurred by a local exchange carrier in providing telephone service. The
FCC has established a rate structure that provides for the recovery of a portion
of the cost of the local loop allocated to that interstate jurisdiction directly
from the end user customer through the assessment of a subscriber line charge.
The remaining portion of the local loop costs are recovered from interstate
access charges to an interexchange carrier or, in some circumstances, from the
federal Universal Service Fund.


                                       73
<PAGE>
    As a result of the market and geographic conditions in rural areas, the
costs of providing local loop and switching services are often higher than in
urban areas. In the absence of an accommodation in the FCC rules to address this
fact, a substantial portion of the costs of smaller local exchange carriers
would remain unrecovered, leaving them little alternative other than to charge
high rates for intrastate services. Accordingly, the FCC provides for additional
interstate recovery by eligible telecommunications carriers through the federal
Universal Service Fund. The federal Universal Service Fund is available to
carriers whose local loop costs are significantly above the national average as
calculated pursuant to FCC rules. Recent FCC rulings have made this high-cost
support available to a competitive carrier, on an averaged per line basis, for
those lines serving customers switching to the competitive carrier.

    INTERSTATE ACCESS RATES

    Interstate access rates are developed on the basis of a local exchange
carrier's measurement of its interstate costs for the provision of access
service to interexchange carriers divided by its projected demand for service.
The resulting rates are published in a company's interstate access tariff and
filed with the FCC, at which time they are subject to challenge by third parties
and to review by the FCC.

    The FCC recognized that this rate making and tariff filing process may be
administratively burdensome for small local exchange carriers. Accordingly, the
FCC established the National Exchange Carriers Association, which is commonly
referred to as NECA, in 1983 to, among other things, develop common interstate
access service rates, terms and conditions. NECA develops interstate access
rates on the basis of data that are provided individually by participating local
exchange carriers and blended to yield average rates. These rates are intended
to generate revenue equal to the aggregate costs plus a return on the investment
of all of the participants. Currently, the authorized rate of return used in
setting interstate access rates is 11.25%.

    Individual participating local exchange carriers are likely to have costs of
providing service that are either higher or lower than the revenues generated by
applying the overall NECA tariff rate. To rectify this result, the revenues
generated by applying the NECA rates are pooled from all of the participating
companies and redistributed on the basis of each individual company's costs. The
result of this process not only eliminates the burden of individual tariff
filing, but also produces a system in which small companies can share and spread
risk. For example, if a smaller local exchange carrier filed its own tariff and
subsequently suffered the loss of major customers that utilize interstate access
service, the local exchange carrier could suffer significant under-recovery of
its costs. In the NECA pool environment, the impact of this loss is reduced
because it is spread over all of the pool participants.


    NECA operates separate pools for traffic sensitive costs, which are
primarily switching costs, and non-traffic sensitive costs, which are primarily
loop costs. Companies are also free to develop and administer their own
interstate access charges. Our rural local exchange carriers participate in both
the traffic sensitive and non-traffic sensitive NECA pools. ATU files its own
traffic sensitive access tariffs with the FCC but participates in the NECA
non-traffic sensitive pool.



    The FCC has initiated a proceeding to review its rates and policies
governing interstate exchange access and the rate of return applicable to
incumbent local exchange carriers who are subject to rate-of-return, rather than
price cap, regulation. Both ATU and our rural local exchange carriers are
rate-of-return regulated, and thus the outcome of this proceeding could directly
affect their earning prospects. The outcome of this proceeding, however, and its
ultimate impact on us, cannot be predicted at this time.


                                       74

    INTRASTATE END USER RATES

    The levels of rates charged to end users for the provision of basic local
service are generally subject to rate-of-return regulation administered by the
RCA. Local rates are typically set at a level that will allow recovery of
embedded costs for local service divided by the number of services and
customers. Recognized costs include an allowance for a rate of return on
investment in plant used to provide local service. Rate cases are typically
infrequent, carrier-initiated and require the carrier to meet substantial
burdens of proof. The last APUC-authorized rates of return were 12.55% and
11.70% for Telephone Utilities of Alaska and Telephone Utilities of the
Northland, respectively. These rates were ordered in 1989. PTI Communications
was previously not regulated by the APUC and instead was regulated by the City
of Fairbanks Public Utilities Board. As a condition of the acquisition of the
City of Fairbanks Telephone Operation by our properties, the APUC required that
a general rate proceeding be initiated for PTI Communications by June 1999. This
proceeding has been delayed and combined with a company-wide earnings review to
be filed with the APUC by June 30, 2001. ATU's last authorized rate of return
was 9.79% for retail local exchange and 10.85% for intrastate access, ordered in
1991.

    The APUC adopted regulations to govern competition in the local exchange
marketplace. The transitional regulations provide for, among other things:

    - initial classification of all incumbent local exchange carriers, including
      our properties and ATU, as dominant carriers,

    - symmetrical requirements that all carriers, both dominant and nondominant,
      offer all retail services for resale at wholesale rates and

    - substantial dominant carrier pricing flexibility in competitive areas,
      under which carriers may reduce retail rates, offer new or repackaged
      services and implement special contracts for retail service upon 30 days'
      notice to the APUC. Only rate increases affecting existing services are
      subject to full cost support showings for local exchange carriers in areas
      with local competition.

    INTRASTATE ACCESS RATES

    In the past, the APUC has required all local companies in Alaska to pool
their access costs and has set an annual statewide average price for access
service. Each local exchange carrier charges interexchange carriers fees for
originating or terminating long distance calls on its network based on the
statewide average cost of access rather than on its costs of access. Access
revenues are collected in a pool administered by the Alaska Exchange Carriers
Association and then redistributed to the local exchange carriers based on their
actual costs. With the passage of the Telecommunications Act and increased
competition in the local exchange market, the APUC began a process of reforming
intrastate access charges.

    Under recent revisions to the Alaska access system, local exchange carriers
not yet subject to local competition continue to participate in the Alaska
Exchange Carriers Association pool. Participants in this pool recover their
costs based on the embedded cost of services most recently authorized by the
APUC. In the event of competitive entry into a dominant carrier's service area,
these revisions also require the dominant local exchange carrier to exit the
pool and initiate separate access charges. Dominant local exchange carriers
subjected to competitive entry have the right to propose that their access
charges be based on market rates.


    An additional consequence of this access reform is the continued removal of
subsidies implicit in access pricing. For instance, the APUC recently abolished
the "weighting system" for the


                                       75
<PAGE>

non-traffic-sensitive rate element that had loaded extra costs on access charges
for lower cost urban exchanges to support rural exchanges. At the same time, the
APUC proposed to support a portion of high switching costs separately through a
state universal service fund. The RCA has subsequently proposed that such state
universal service support be available only to local companies with access lines
of 20,000 or less. If adopted as proposed, this limitation would reduce the
amount of state universal service support which our rural local exchange
carriers would receive in the future.


    The Alaska Universal Service Fund serves as a complement to the federal
Universal Service Fund, but must meet federal statutory criteria concerning
consistency with federal rules and regulations. Currently, the Alaska Universal
Service Fund only subsidizes a portion of higher cost carriers' switching costs,
and the costs of lifeline service--supporting rates of low income customers. The
APUC indicated that it might have considered expanding the Alaska Universal
Service Fund's coverage in the future, such as to support the costs of public
interest pay telephones. The RCA has proposed to subject existing support paid
to carriers for switching costs to an access line threshold which could reduce
or eliminate such support for some of our subsidiaries. Further litigation has
been initiated in state court to determine the lawfulness of the Alaska
Universal Service Fund as currently established.

THE TELECOMMUNICATIONS ACT

    Among other things, the Telecommunications Act was enacted to enhance
competition without jeopardizing the availability of nationwide universal
service at affordable rates. These two objectives have resulted in a complex set
of rules intended to promote competitive entry in the provision of local
telephone services, except where entry would adversely effect the provision of
universal service or the public interest.

    PROMOTION OF LOCAL SERVICE COMPETITION AND THE RURAL EXEMPTIONS

    The Telecommunications Act made competitive entry into the local telephone
business more attractive to other carriers by removing barriers to competition.
In order to promote competition, the Telecommunications Act established new
interconnection rules generally requiring local exchange carriers to allow
competing carriers to interconnect with their local networks. Congress
recognized, however, that when the desire to promote competition conflicted with
the ability of existing carriers to provide universal service to higher cost
customers, local exchange carriers classified as "Rural Telephone Companies"
should be exempted from interconnection requirements until the continuation of
the exemption was no longer required by the public interest, as defined in the
Telecommunications Act.

    Under the Telecommunications Act, all local exchange carriers, including
both incumbent local exchange carriers and new competitive carriers, are
required to:

    - offer reasonable and nondiscriminatory resale of their telecommunications
      services,

    - ensure that customers can keep their telephone numbers when changing
      carriers,

    - ensure that competitors' customers can use the same number of digits when
      dialing and receive nondiscriminatory access to telephone numbers,
      operator service, directory assistance and directory listing,

    - ensure access to telephone poles, ducts, conduits and rights of way and

    - compensate competitors for the costs of terminating traffic.

                                       76
<PAGE>
    The Telecommunications Act also requires incumbent local exchange carriers
to:


    - negotiate in good faith the terms and conditions of interconnection with
      any competitive carrier making a request for same,


    - interconnect their facilities and equipment with any requesting
      telecommunications carrier at any technically feasible point,

    - unbundle and provide nondiscriminatory access to unbundled network
      elements, such as local loops, switches and transport facilities, at
      nondiscriminatory rates and on nondiscriminatory terms and conditions,

    - offer resale interconnection at wholesale rates,

    - provide reasonable notice of changes in the information necessary for
      transmission and routing of services over the incumbent local exchange
      carrier's facilities or in the information necessary for interoperability
      and

    - provide for the physical collocation of equipment necessary for
      interconnection or access to unbundled network elements at the premises of
      the incumbent local exchange carrier, at rates, terms and conditions that
      are just, reasonable and nondiscriminatory.

    In order to implement interconnection requirements, local exchange carriers
generally enter into negotiated interconnection arrangements with competing
carriers. Local exchange carriers may also offer interconnection tariffs,
available to all competitors.


    Competitors are required to compensate a local exchange carrier for the cost
of providing interconnection services. In the case of resale interconnection,
the rules provide that the rates charged should be on a wholesale basis and
reflect the current retail rates of the incumbent local exchange carrier,
excluding the portion of costs avoided by the incumbent local exchange carrier.
In the case of unbundled network element interconnection, rates are based on
costing methodologies that employ a forward-looking economic cost pricing
methodology known as total element long run incremental cost. While the Supreme
Court recently affirmed the FCC's authority to develop pricing guidelines, the
Supreme Court did not evaluate this pricing methodology. Some incumbent local
exchange carriers have argued that total element long run incremental cost
pricing methodology does not allow adequate compensation for the provision of
unbundled network elements. The Eighth Circuit Court of Appeals heard oral
arguments on this pricing issue on September 16, 1999, but has not yet issued a
ruling.


    The Telecommunications Act specifies that resale and unbundled network
element rates are to be negotiated among the parties, or, if the parties fail to
reach an agreement, arbitrated by the relevant state regulatory authority. Once
the parties have come to agreement, the proposed rates are subject to final
approval by the state regulatory commission.


    The Supreme Court has also recently upheld the FCC's authority to prevent
the incumbent local exchange carrier from disaggregating existing combinations
of network elements and to establish "pick and choose" rules regarding
interconnection agreements. "Pick and choose" rules would permit a carrier
seeking interconnection to pick and choose among the terms of service from other
interconnection agreements between the incumbent and local exchange carriers and
other competitors.



    The Supreme Court also remanded the list of unbundled network elements that
the FCC adopted for further consideration of the necessity of each one under the
statutory standard. On September 15, 1999, the FCC adopted an order eliminating
some previously included unbundled


                                       77
<PAGE>

network elements, but increasing the number of sub-elements associated with the
local loop. These new FCC rules are likely to be the subject of further appeals.


    In January 1997, ATU entered into an interconnection agreement with GCI,
which provides for resale and unbundled network element interconnection, and
with AT&T Alascom, which provides for resale interconnection.


    Our local operating utilities, Telephone Utilities of Alaska, Telephone
Utilities of the Northland, and PTI Communications, are defined as "rural
telephone companies" under the Telecommunications Act. As rural telephone
companies, they were granted rural exemptions from the requirements relating to
both resale interconnection and unbundled network element interconnection. The
rural exemptions were continued until the APUC determined that interconnection
was technically feasible, not unduly economically burdensome and consistent with
the Telecommunications Act's universal service provisions.



    On June 30, 1999, the APUC ordered the rural exemptions of Telephone
Utilities of the Northland, Telephone Utilities of Alaska, and PTI
Communications terminated. On October 11, 1999, the RCA affirmed the APUC's
order. As a result, these rural local exchange carriers are no longer exempt
from the Telecommunications Act's interconnection requirements applicable to
incumbent local exchange carriers, and are now engaged in the negotiation of
interconnection agreements with potential competitors. We cannot be certain that
we will be able to charge rates which fairly compensate us for providing
unbundled network elements and/or schedule discounted resale services.



    Separately, on September 1, 1999, we filed petitions with the RCA seeking
suspension or modification of interconnection duties and addressing market
structure reforms for the Fairbanks and Juneau-Douglas markets. In those
petitions, our rural local exchange carriers proposed tariffed terms and
conditions, including pricing, for resale of their services at wholesale
discounts, for certain unbundled network elements, and for the interconnection
of their facilities and those of competitive local exchange carriers in the
Fairbanks and Juneau-Douglas markets, effective January 1, 2000. Further, as
part of that proposal, we also requested that the RCA permit our local exchange
carriers to operate subject to competitive regulation and that the RCA remove or
reduce other regulatory limitations in those markets, effective January 1, 2001.
On October 22, 1999, the RCA issued a preliminary order indicating that it would
not address interconnection issues in tariff proceedings. The RCA has not yet
issued a full order explaining its determination.



    In April 1999, a bill was proposed in the Alaska state senate to open to
competition many local telephone markets in which we operate. Specifically, the
bill proposed to allow competitors to provide local telephone service in local
telephone markets throughout Alaska that have at least 5,000 access lines,
effectively depriving incumbent local exchange carriers in those markets of
their rural exemptions. Competition resulting from this bill, if it had been
enacted into law, could have materially adversely affected our profitability.
Although this bill was not enacted into law, we cannot predict at this time
whether or to what extent proposals included in the bill will be offered again
and enacted into law.



    For the first nine months of 1999, our local exchange carriers benefiting
from rural exemptions accounted for 41.7% of our revenues and 53.8% of our
operating income. Loss of the rural exemptions, absent compensating measures,
such as rate increases, or market structure reforms, such as the replacement of
implicit subsidies by explicit support mechanisms, or rate deaveraging, could
adversely affect our operating results.


                                       78

    PROMOTION OF UNIVERSAL SERVICE

    While the Telecommunications Act promoted Congress' policy of ensuring that
affordable service is provided to consumers universally in rural, high-cost
areas of the country, the Telecommunications Act altered the framework for
providing universal service by:

    - providing for the identification of those services eligible for universal
      service support,

    - requiring the FCC to make implicit subsidies explicit,

    - expanding the types of communications carriers required to pay universal
      service support and

    - allowing competitive local exchange carriers to be eligible for funding.

These and other provisions were intended to make provision of universal service
support compatible with a competitive market.


    Pursuant to the Telecommunications Act, federal Universal Service Fund
payments are only available to carriers that are designated as eligible
telecommunications carriers by a state public utilities commission. In areas
served by rural local exchange carriers, the Telecommunications Act provides
that a state public utilities commission may designate more than one eligible
telecommunications carrier, in addition to the incumbent local exchange carrier,
only after determining that the designation of an additional eligible
telecommunications carrier is consistent with the public interest. As a result,
an incumbent rural local exchange carrier has an opportunity to maintain its
status as the sole recipient of federal Universal Service Fund payments in its
service area, even if it is subsequently subjected to competition. Telephone
Utilities of Alaska, Telephone Utilities of the Northland and PTI Communications
are currently the sole designated eligible telecommunications carriers in their
respective service areas. The addition of a second eligible telecommunications
carrier in the service areas of our properties could have the effect of reducing
the amount of funds available from the federal Universal Service Fund and could
materially adversely affect our ability to achieve a reasonable rate of return
on the capital invested in our network.



    In May 1997, the FCC initiated new proceedings addressing federal universal
service support. The new proceedings undertook to separately analyze and address
federal Universal Service Fund requirements and considerations for rural and for
non-rural telephone companies. The FCC indicated its intention that new rules
for universal service support of non-rural companies would be based on
forward-looking economic cost principles as applied through cost proxy models.
On October 21, 1999, the FCC issued orders addressing specific implementation
matters for providing universal service support to non-rural carriers. The FCC
established cost input parameters for use in the cost proxy models, upon which
universal service support payments to non-rural carriers would be based in the
future. The FCC also established procedures for allocating universal service
support for non-rural carriers among and between the states. This new system of
universal service support applies only to non-rural carriers and will become
effective January 1, 2000.



    With respect to universal service support for rural telephone companies, the
FCC established a Rural Task Force in 1997 to investigate rural carrier
universal service needs, including issues concerning whether and how cost proxy
models adopted for non-rural carriers could be applied to rural telephone
companies. The FCC has indicated several times that it will not implement a new
universal service support system for rural telephone companies sooner than
January 1, 2001 and may delay any implementation beyond that date. The
October 21, 1999 order described above applies only to non-rural carriers.


                                       79
<PAGE>

    Separately, the FCC has requested comments concerning ways to promote basic
and advanced services to unserved and underserved areas. As a part of these
proceedings, the FCC is reviewing its authority to designate certain types of
telecommunications carriers, such as wireless carriers, as eligible to receive
payments from the universal service fund. Any determinations concerning such
eligibility could affect either our rural local exchange carriers, our wireless
carrier, or both, but we cannot predict the outcome of these proceedings at
present.



    On July 30, 1999, the U.S. Court of Appeals for the Fifth Circuit overturned
certain of the FCC's rules governing the basis on which the FCC collects subsidy
payments from telecommunications carriers and recovery of those payments by
incumbent local exchange carriers. One or more parties to that litigation may
seek review by the Supreme Court. On October 8, 1999, the FCC revised its
universal service rules in response to the decision by the Fifth Circuit. Among
other things, these revised rules provide that intrastate revenue earned by a
contributing carrier will not be considered in determining the amount of the
contribution to the federal universal service fund.



    OTHER PROCEEDINGS



    A number of other FCC, state and judicial proceedings are currently pending
or may be initiated in the future which could materially affect our business.
Some of these proceedings include:



    - The U.S. Court of Appeals for the Tenth Circuit has held that the FCC's
      rules limiting the ways in which carriers may use certain types of
      customer information are an unconstitutional abridgment of the carrier's
      freedom of speech. The FCC has asked the Tenth Circuit to reconsider its
      decision.



    - The FCC has adopted new rules designed to make it easier for customers to
      understand the bills of telecommunications carriers. These new rules,
      among other things, establish certain requirements regarding the
      formatting of bills and the information that must be included on bills.
      Judicial review of these rules is pending.



    - The FCC has requested comment on its authority to designate certain types
      of telecommunications carriers, such as wireless carriers, as eligible to
      receive federal universal service support. We cannot predict how the FCC
      will interpret its authority in this regard, or how the FCC's exercise of
      its authority will affect our business.



    The foregoing is not an exhaustive list of proceedings that could materially
affect our business. We cannot predict the outcome of these or any other
proceeding before the FCC, the RCA or the courts.

COMMITTEES OF THE BOARD OF DIRECTORS


    Upon completion of the offering, our board of directors will establish an
Audit Committee, a Compensation Committee and an Executive Committee. The
functions of the Audit Committee will be to:


    - recommend annually to our board of directors the appointment of our
      independent auditors,

    - discuss and review in advance the scope and the fees of our annual audit
      and review the results thereof with our independent auditors,

    - review and approve non-audit services of our independent auditors,

    - review compliance with our existing major accounting and financial
      reporting policies,

    - review the adequacy of major accounting and financial reporting policies
      and

    - review our management's procedures and policies relating to the adequacy
      of our internal accounting controls and compliance with applicable laws
      relating to accounting practices.

We anticipate that the Audit Committee will consist solely of directors who are
not otherwise our employees.

    The functions of the Compensation Committee will be to review and approve
annual salaries, bonuses, and grants of stock options under our stock incentive
plans for all executive officers and other key members of management, and to
review and approve the terms and conditions of all

                                       83
<PAGE>
employee benefit plans or changes to these plans. We anticipate the Compensation
Committee will consist of directors who are not otherwise our employees.

    The Executive Committee will have the authority to exercise the powers of
our board of directors, other than those reserved to the Audit Committee and the
Compensation Committee or to our full board of directors, between meetings of
our full board of directors.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION


    As noted above, our board of directors does not currently have a
Compensation Committee, but we anticipate establishing one in connection with
the offering. Prior to this offering, our controlling stockholder and senior
management were directly involved in setting compensation for our executives.


COMPENSATION OF DIRECTORS


    As noted above, our board of directors does not currently have a
Compensation Committee, but we anticipate establishing one in connection with
the offering. Upon its formation, the Compensation Committee will formulate
policies for compensating non-employee directors, including meeting fees and
annual retainers. We currently do not, and we will continue not to, compensate
our employee directors for serving as directors. We will reimburse all directors
for reasonable and necessary expenses they incur in performing their duties as
directors.



    ALASKA COMMUNICATIONS SYSTEMS GROUP, INC. 1999 NON-EMPLOYEE DIRECTOR STOCK
    COMPENSATION PLAN



    In connection with the offering, we intend to adopt the Alaska
Communications Systems Group, Inc. 1999 Non-Employee Director Stock Compensation
Plan. The purpose of this plan will be to promote a greater identity of
interests between our non-employee directors and our stockholders and to attract
and retain individuals to serve as directors.



    The plan will be administered by our board of directors or a committee of
our board of directors designated for this purpose.



    Our non-employee directors will be eligible to participate in the plan as of
the date of the pricing of this offering. A total of 150,000 shares of common
stock will be reserved for issuance and available for grants under the plan.



    Our board of directors or its designated committee may adjust the awards
under the plan if there is any change in corporate capitalization, such as a
stock split, or a corporate transaction, such as a merger, consolidation,
separation, including a spin-off, or other distribution of our stock or
property, any reorganization or any partial or complete liquidation.



    Each non-employee director, other than directors affiliated with Fox Paine,
will receive a portion of his or her annual retainer and meeting fees in shares
of common stock. In addition, non-employee directors may make an annual
irrevocable election to receive shares of common stock in lieu of all, or a
portion, of such director's remaining fees. The number of shares of common stock
granted to a director will be equal to the appropriate percentage of fees
payable to the director in each calendar quarter, divided by the fair market
value of a share of common stock on the last business day of the calendar
quarter. We will round the number of shares granted to the director down to the
nearest whole share of common stock and pay cash for the value of any fractional
share. Each director may defer the receipt of his or her cash payments into an
interest-bearing cash account and/or his or her elected or mandatory shares of
common stock into a share account which will be credited with additional shares
having a value equal to the dividends that would be paid on the shares credited
to the share account, if they were outstanding. When the director


                                       84
<PAGE>

leaves our board of directors or, if earlier, upon a change of control, the
amount of cash in his or her cash account, plus a number of shares of common
stock equal to the number of shares in his or her share account will be
delivered to the director, with cash being paid in lieu of any fractional
shares.



    Grants and awards under the plan are nontransferable other than by will or
the laws of descent and distribution, or at the discretion of our board of
directors or the designated committee, by a written beneficiary designation.



    Our board of directors may at any time terminate or amend the plan, except
that no termination or amendment may impair the rights of directors relating to
outstanding awards. No amendment will be made without the approval of our
stockholders to the extent such approval is required by law or stock exchange or
automated quotation system rule.


EXECUTIVE COMPENSATION

    Prior to the acquisitions of Century's Alaska properties and ATU on May 14,
1999, none of our executive officers was compensated by us or any of our
subsidiaries to any meaningful extent. As a result, individual information for
our directors and executive officers is not provided for periods prior to
May 14, 1999. The following table shows current cash compensation, assuming a
full year and the payment of maximum targeted bonuses, for our Chief Executive
Officer and each of our four other most highly compensated executive officers

    years (three years in the case of Mr. Robinson) following the date of grant,
    in equal installments, if corporate financial goals established under our

    will be accelerated upon completion of the offering.



(2) These stock options will vest upon completion of the offering. Each
    executive officer has agreed not to dispose of more than 20% of the shares
    he may receive upon exercise of these options before each anniversary
    following the date of grant of the options.

(1) The fair market value of stock options as of September 30, 1999 was assumed
    to be $10.12 per share, based upon an independent business valuation, due to
    the lack of a public trading market for the securities underlying the stock
    options.

EMPLOYMENT ARRANGEMENTS

    Before completion of the acquisitions of Century's Alaska properties and
ATU, we entered into new employment arrangements with some of our employees
relating to their employment with us and Alaska Communications Systems Holdings,
their ownership of our common stock and the granting of options to purchase
shares of our common stock following the completion of these acquisitions.


    EMPLOYMENT AGREEMENT WITH CHARLES E. ROBINSON.  Under the employment
agreement among Alaska Communications Systems Group, Alaska Communications
Systems Holdings and Charles E. Robinson, dated as of March 12, 1999,
Mr. Robinson served as the Chairman of the Board, Chief Executive Officer and
President of Alaska Communications Systems Group and Alaska Communications
Systems Holdings for a three-year period, which will be extended automatically
for successive additional one-year periods unless either our board of directors,
or Mr. Robinson gives no less than 90 days written notice of an intention not to
extend the term. On October 7, 1999, Mr. Carson became President and Chief
Operating Officer of Alaska Communications Systems Group, while Mr. Robinson
retained his title of Chairman of the Board and Chief Executive Officer.
Mr. Robinson will receive an initial annual base salary of $500,000, which may
be increased at the beginning of each year following the first year of
employment. Mr. Robinson will be eligible for an annual bonus equal to 100% of
his annual base salary for each calendar year based on our attainment of
mutually determined business targets, with appropriate adjustments to the extent
we exceed or fail to reach these targets. In no event will Mr. Robinson's annual
bonus be less than $200,000. Mr. Robinson's employment agreement also provides
for other customary benefits including fringe benefit plans, paid vacation, life
and disability insurance plans and expense reimbursement.



    Under the Robinson employment agreement, if Mr. Robinson's employment were
to be terminated by Mr. Robinson for good reason or following a change in
control or by Alaska Communications Systems Group without cause, we would be
obligated to pay Mr. Robinson a lump sum cash payment in an amount equal to the
sum of:


    - Mr. Robinson's annual base salary, as then in effect plus

    - Mr. Robinson's most recent annual bonus, as well as reimbursement for the
      cost of continuing health insurance coverage under COBRA for twelve
      months.

In addition, upon the termination of Mr. Robinson's employment, the number of
then-unvested options will vest as are necessary to vest at least one-third of
all options received by Mr. Robinson. In addition, in the event we decide at any
time not to extend the term of his employment agreement, we will pay
Mr. Robinson the sum of:

    - Mr. Robinson's annual base salary, as then in effect, plus

    - Mr. Robinson's most recent annual bonus plus

    - reimbursement for the cost of continuing health insurance coverage under
      COBRA for twelve months.

    The employment agreement with Mr. Robinson also provides that during his
employment and during the 12-month period following any termination of his
employment, Mr. Robinson will not directly or indirectly own, make equity or
debt investments in, manage, control, participate in, consult with, advise,
render services to, or in any manner engage in, or be connected as an employee,
officer, partner, director, consultant or otherwise with:

    - any enterprise engaged in the provision of local exchange or wireless
      telecommunications services in any state in which:

       - we, our affiliates or subsidiaries or

                                       87
<PAGE>
       - any entity that is a party to an acquisition agreement with us, our
         affiliates or subsidiaries

    is engaged in the provision of local exchange or wireless telecommunications
services, or

    - any enterprise that is the subject of a potential transaction made known
      to us, our affiliates or subsidiaries, or Mr. Robinson during or at any
      time prior to the termination of his employment agreement, that is engaged
      in the provision of local exchange or wireless telecommunications
      services.

However, Mr. Robinson may be a passive owner of not more than one percent of any
publicly traded class of capital stock of any entity engaged in the provision of
local exchange or wireless telecommunications services. The Robinson employment
agreement also provides for other non-inducement and non-solicitation
restrictions during Mr. Robinson's employment and during the 12-month period
following any termination of his employment.


    EMPLOYMENT AGREEMENT WITH WESLEY E. CARSON.  Under the employment agreement,
dated March 12, 1999, by and among Alaska Communications Systems Group, Alaska
Communications Systems Holdings and Wesley E. Carson, Mr. Carson served as
Executive Vice President of us and Alaska Communications Systems Holdings for a
two-year initial term at an annual base salary of $200,000. On October 7, 1999,
Mr. Carson assumed the title of President and Chief Operating Officer of Alaska
Communications Systems Group. Previously, Mr. Robinson held the title of
President. Mr. Carson's employment agreement generally contains provisions
similar to those in Mr. Robinson's employment agreement, except that:


    - Mr. Carson does not have a guaranteed minimum annual bonus and Mr. Carson
      will receive no annual bonus if termination occurs prior to December 31,
      1999 and

    - Mr. Carson's employment agreement does not provide any additional rights
      with respect to vesting of then-unvested options upon termination.

    OTHER EMPLOYMENT ARRANGEMENTS.  We have made additional employment
commitments to other of our officers on terms and conditions substantially
similar to those in the employment agreement with Mr. Carson.

ALEC HOLDINGS, INC. 1999 STOCK INCENTIVE PLAN

    In connection with the completion of the acquisitions of Century's Alaska
properties and ATU, we adopted the ALEC Holdings, Inc. 1999 Stock Incentive Plan
under which we may grant incentive awards in the form of options to purchase
shares of our common stock, restricted shares of our common stock and stock
appreciation rights to participants, which include non-employee directors,
officers, employees and consultants of us and our affiliates. The total number
of shares of our common stock initially reserved and available for grant under
the stock incentive plan is 3,410,486 shares. A committee of our board of
directors, or our board of directors itself in the absence of a committee, is
authorized to make grants and various other decisions under the stock incentive
plan. Unless otherwise determined by the committee, any participant granted an
award under the stock incentive plan must become a party to, and agree to be
bound by, the stockholders' agreement.

    Stock options may include incentive stock options, nonqualified stock
options or both, in each case, with or without stock appreciation rights. Stock
options are generally nontransferable and, unless otherwise determined by the
committee, have a term of ten years. Upon a participant's death or when the
participant's employment with us or the applicable affiliate of us is terminated
for any reason, the participant's then-unvested stock options are forfeited and
the participant or his or her legal representative may, within three months if
termination of employment is for any reason other than death, or one year in the
case of the participant's death, exercise any previously vested stock options.
Stock appreciation rights may be granted in conjunction with all or part of any
stock option award and are generally exercisable only in connection with the
exercise of the related stock

                                       88
<PAGE>
option. Upon termination or exercise of the related stock option, stock
appreciation rights terminate and are no longer exercisable. Stock appreciation
rights are transferable only with the related stock options. Unless otherwise
provided in the related award agreement or, if applicable, the stockholders'
agreement, immediately prior to the change of control transactions described in
the stock incentive plan, all outstanding stock options and stock appreciation
rights will become fully exercisable and vested, and any restrictions and
deferral limitations applicable to any restricted stock awards will lapse. The
committee may also grant to any participant, on terms and conditions determined
by the committee, the right to receive cash payments to be paid at that time as
an award results in compensation income to the participant in order to assist
the participant in paying the resulting taxes.

    The stock incentive plan will terminate on May 14, 2009. However, awards
outstanding at that time will not be affected or impaired by the stock incentive
plan's termination. Our board of directors and the committee have authority to
amend the stock incentive plan and awards granted thereunder.


    On May 14, 1999 we issued options to purchase 2,244,500 shares of common
stock to some of our employees and a consulting firm; on May 24, 1999 we issued
options to purchase 250,000 shares of common stock to some of our employees; on
May 25, 1999 we issued options to purchase 250,000 shares of common stock to
some of our employees; on June 1, 1999 we issued options to purchase 25,000
shares of common stock to some of our employees; on June 9, 1999 we issued
options to purchase 15,000 shares of common stock to some of our employees; and
on June 25, 1999 we issued options to purchase 73,500 shares of common stock to
some of our employees. For all of these options, 10% vest on each anniversary of
their grant for a period of five years (16 2/3% for a period of three years in
the case of Mr. Robinson) and an additional 50% of the options vest on the ninth
year of the date of grant, and vesting will be accelerated to each January 1 of
the five years (three years in the case of Mr. Robinson) following the date of
grant, in equal installments, if corporate financial goals established under our
stock incentive plans are obtained. The vesting of 508,750 performance-based
options of Mr. Robinson, however, will be accelerated upon completion of the
offering. In addition, vesting of 145,000 performance-based options held by two
other employees will be accelerated upon completion of the offering. These
employees have agreed not to dispose of more than 20% of the shares they may
receive upon exercise of these options before each anniversary following the
date of grant of the options (plus any shares permitted to be disposed of, but
not disposed of, in any previous year). On September 28 and October 25, 1999, we
issued options to purchase 470,000 and 4,000 shares of common stock,
respectively, to some of our employees, all of which will vest upon completion
of the offering. The employees to whom these options have been granted have
agreed not to dispose of more than 20% of the shares they may receive upon
exercise of these options before each anniversary following September 28 or
October 25, 1999, the dates of grant of the options (plus any shares permitted
to be disposed of, but not disposed of, in any previous year). We had an
independent appraisal of the fair market value of these recently granted
options. Based upon this appraisal, we recorded $1,864,000 of deferred
compensation which will be charged to expense upon completion of the offering.



    Additionally, as discussed above, 653,750 of the options granted in May 1999
under the ALEC Holdings, Inc. 1999 Stock Incentive Plan are performance-vesting
options that vest upon completion of the offering. Based upon the midpoint of
the initial public offering price range set forth on the cover of this
prospectus we would record compensation expense of $5,129,000 following the
offering.

ALASKA COMMUNICATIONS SYSTEMS GROUP, INC. 1999 STOCK INCENTIVE PLAN



    In connection with the offering, we intend to adopt and approve the Alaska
Communications Systems Group, Inc. 1999 Stock Incentive Plan. This plan is
designed to promote our success and enhance our value by linking the interests
of our officers, employees and consultants to those of our stockholders and by
providing participants with an incentive for outstanding performance. This plan
is further intended to provide flexibility in its ability to motivate, attract
and retain employees upon whose judgment, interest and special efforts our
business is largely dependent. Our officers, employees and consultants,
including employees who are members of our board of directors, and officers,
employees and consultants of our subsidiaries and affiliates are eligible to
participate in this plan. Non-employee directors are not eligible to participate
in this plan. This plan is intended to remain in effect until 2009. The
description below summarizes the material terms of this plan.



    GENERAL



    The plan will be administered by the Compensation Committee of our board of
directors, or another committee designated by our board of directors, and
provides for the grant of stock options, both non-qualified and incentive stock
options and other types of equity-based awards.



    The plan provides that the maximum number of shares of common stock
available for grant under the 1999 plan is 1,500,000.



    The term of options granted under the plan may not exceed 10 years. Unless
otherwise determined by our Compensation Committee, options will vest ratably on
each of the first four anniversaries after the grant date and will have an
exercise price equal to the fair market value of the common stock on the date of
grant.



    A participant exercising an option may pay the exercise price in cash or, if
approved by our Compensation Committee, with previously acquired shares of
common stock or in a combination of cash and stock. Our Compensation Committee,
in its discretion, may allow the cashless exercise of options.



    Options are nontransferable other than by will or the laws of descent and
distribution or, at the discretion of our Compensation Committee, by a written
beneficiary designation and, in the case of a non-qualified option, by a gift to
members of the holder's immediate family. The gift may be made directly or
indirectly or by means of a trust or partnership or limited liability company
and, during the participant's lifetime, may be exercised only by the
participant, any such permitted transferee or a guardian, legal representative
or beneficiary.



    OTHER AWARDS



    A stock appreciation right, or SAR, permits a participant to receive cash or
shares of common stock, or a combination thereof, as determined by our board of
directors or our Compensation Committee. The amount of cash or the value of the
shares is equal to the excess of the fair market value of a share of common
stock on the date of exercise over the SAR exercise price, multiplied by the
number or shares with respect to which the SAR is exercised. Restricted stock
may be granted subject to performance or service-based goals upon which
restrictions will lapse. Performance units or restricted units may be granted
subject to performance goals and/or service-based restrictions, and will be
payable in cash or shares of common stock or a combination as determined by our
board of directors or our Compensation Committee. Dividend and interest
equivalents with respect to awards, and other awards based on the value of
common stock, may also be granted.


                                       90
<PAGE>

    CHANGE IN CONTROL



    In the event of a change in control, any option or SAR that is not then
exercisable and vested will become fully exercisable and vested, restrictions on
restricted stock will lapse and performance units will be deemed earned. Change
in control generally means:



    - the acquisition of an amount of common stock greater than the amount held,
      directly or indirectly, by Fox Paine, our controlling stockholder, and
      representing at least 30% of the outstanding common stock or voting
      securities,



    - a change in the majority of the members of the board of directors, unless
      approved by the incumbent directors or Fox Paine,



    - the completion of a merger or other business combination involving Alaska
      Communications Systems Group in which, among other things, our
      stockholders fail to retain more than 50% of the common stock and voting
      power or



    - approval by our stockholders of a complete liquidation or dissolution or
      sale of substantially all of our assets.



    AMENDMENTS



    Our board of directors may at any time amend or terminate the plan and may
amend the terms of any outstanding option or other award, except that no
termination or amendment may impair the rights of the participants as they
relate to outstanding options or awards. However, no such amendment to the plan
will be made without the approval of our stockholders to the extent such
approval is required by law or stock exchange or automated quotation system
rule.



ALASKA COMMUNICATIONS SYSTEMS GROUP, INC. 1999 EMPLOYEE STOCK PURCHASE PLAN



    In connection with the offering, we intend to adopt the Alaska
Communications Systems Group, Inc. 1999 Employee Stock Purchase Plan. The
purpose of the purchase plan will be to further our long-term stability and
financial success by providing a method for employees to increase their
ownership of common stock. Under the purchase plan, 1,000,000 shares of common
stock will be available for issuance and sale. Unless sooner terminated at the
discretion of our board of directors, the purchase plan will terminate on
December 31, 2009.



    ELIGIBILITY



    All of our employees and all of the employees of designated subsidiaries
generally will be eligible to participate in the purchase plan, other than
employees whose customary employment is 20 hours or less per week or is for not
more than five months in a calendar year, or who are ineligible to participate
due to restrictions under the Internal Revenue Code.



    GENERAL DESCRIPTION



    A participant in the purchase plan may authorize regular salary deductions
of a maximum of 15% and a minimum of 1% of base compensation. The fair market
value of shares which may be purchased by any employee during any calendar year
may not exceed $25,000. The amounts so deducted and contributed will be applied
to the purchase of full shares of common stock under options to purchase shares
at 85% of the lesser of the fair market value of such shares on the date of
purchase or on the offering date for such offering period. The offering dates
will be January 1 and July 1 of each purchase plan year, and each offering
period will consist of one six-month purchase period. Any offering period,
however, beginning in 1999 would be commenced after July 1, and would be for
less than a six-month period. Shares will be purchased for participating


                                       91
<PAGE>

employees on the last business days of June and December for each purchase plan
year and each such participant will have the rights of a stockholder with
respect to such shares.



    Participants may decrease their payroll deductions at any time but not more
than once during any offering period. Participants may increase or decrease
their payroll deductions for any subsequent offering period by notifying the
purchase plan administrator no later than 15 days prior to such offering period.
Participants may also withdraw from participation in the purchase plan at any
time on or prior to the 15th day of the last month of the offering period. If a
participant withdraws from the purchase plan, any contributions that have not
been used to purchase shares will be refunded. A participant who has withdrawn
may not participate in the purchase plan again until the next offering period.



    In the event of retirement or other termination of employment before the
15th day of the last month in the offering period, any contributions that have
not yet been used to purchase shares will be refunded and a certificate issued
for the full shares in the participant's account. In the event of a
participant's death, any contributions that have not yet been used to purchase
shares and all shares in such participant's account will be delivered to the
participant's beneficiary designated in writing and filed with us, or, if no
beneficiary has been designated or survives the participant, to the
participant's estate. Any payroll deductions that have not been used to purchase
shares will be returned to the participant after the end of the applicable
offering period.



    AMENDMENTS OR TERMINATION OF THE PURCHASE PLAN



    Our board of directors may amend the purchase plan in any respect, although
our stockholders must approve any amendment that would increase the number of
securities that may be issued under the purchase plan or would cause the plan to
fail to qualify for beneficial tax treatment under Section 423 of the Internal
Revenue Code. Our board of directors may suspend or terminate the purchase plan
at any time. However, in the event of a termination while an offering period is
in progress, our Compensation Committee may return accumulated payroll
deductions or shorten the offering period by setting a new date of purchase.


STOCKHOLDERS' AGREEMENT

    On May 14, 1999, we entered into a stockholders' agreement with Fox Paine
Capital Fund, investors affiliated with Fox Paine Capital Fund and several
non-fund investors, including co-investors and some of our employees listed on
the signatures pages to the stockholders' agreement. Since May 14, 1999,
additional parties, including Cook Inlet, have been added to the stockholders'
agreement. The following is a summary of the material terms of the stockholders'
agreement and is qualified in its entirety by reference to the stockholders'
agreement, which has been filed as an exhibit to the registration statement of
which this prospectus is a part.

    TRANSFER RESTRICTIONS.  The stockholders' agreement contains general
restrictions on the ability of our stockholders to transfer their shares of
common stock. In addition, if Fox Paine Capital Fund and its affiliates desire
to sell or dispose of all their shares of common stock, they have the right to
require the non-fund investors to sell all of their shares of common stock on a
pro rata basis and on the same terms and conditions in that transaction. The
non-fund investors have tag-along rights which enable them to participate on a
pro rata basis and on the same terms and conditions in sales of shares of common
stock by Fox Paine Capital Fund and its affiliates other than sales made
pursuant to Rule 144 under the Securities Act.

    REGISTRATION RIGHTS.  Under the stockholders' agreement, following
completion of the offering and subject to limited exceptions,

    - Fox Paine Capital Fund and its affiliates, as a group, may make up to six
      demands for registration under the Securities Act of their shares of
      common stock,

                                       92
<PAGE>
    - Affiliates of Donaldson, Lufkin & Jenrette Securities Corporation, or
      holders of at least 25% of the shares of common stock presently owned by
      DLJ, may make one demand for registration under the Securities Act of
      their shares of common stock and

    - Cook Inlet, or holders of at least 25% of the shares of common stock
      presently owned by Cook Inlet, may make one demand for registration under
      the Securities Act of its shares of common stock.

    Upon any demand for registration by any of Fox Paine Capital Fund and its
affiliates, DLJ or Cook Inlet, each of our other stockholders will be given the
opportunity to participate on a pro rata basis in the registration demanded. The
stockholders' agreement also provides the stockholders with piggyback
registration rights which allow each of them to include all or a portion of
their shares of common stock under a registration statement filed by us, subject
to limited exceptions. The stockholders have agreed not to exercise their
piggyback registration rights with respect to the offering.

    OTHER AGREEMENTS.  Pursuant to the stockholders' agreement, each of our
stockholders has agreed at all times during the term of the stockholders'
agreement, not to act as a member of a group or in concert with others in
connection with the acquisition, disposition or voting of shares of common stock
in any manner inconsistent with the stockholders' agreement.

    Provisions in the stockholders' agreement that

    - preclude stockholders from granting any proxy or entering into any voting
      trust with respect to our common stock or entering into any stockholder
      agreement or arrangement inconsistent with the provisions of the
      stockholders' agreement or

    - grant members of management various rights to put or call their shares of
      common stock

expire upon completion of the offering.

    TERMINATION.  The rights and obligations described under "--Transfer
Restrictions" will terminate when

    - Fox Paine Capital Fund and its affiliates own less than 20% of the fully
      diluted shares of common stock then outstanding or

    - in the case of the shares of common stock issued upon exercise of the
      warrants issued in connection with the senior discount debentures,
      following completing of the offering.


    In addition, the stockholders' agreement will terminate upon any
recapitalization, consolidation, reorganization or other restructuring of Alaska
Communications Systems Group as a result of which parties to the stockholders'
agreement and their permitted transferees own less than a majority of the
outstanding voting power of the entity surviving that recapitalization,
consolidation, reorganization or other restructuring. After such a transaction,
only rights and obligations described under "--Registration Rights" will survive
until the earlier of


    - May 14, 2019 or

    - the date when there are no longer any shares outstanding or issuable upon
      exercise or conversion of any options, warrants, rights or other
      convertible securities that remain to be registered.

Rights and obligations under the stockholders' agreement relating to
indemnification will survive indefinitely.

              INSIDER RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

    In connection with the execution of the purchase agreement relating to
Century's Alaska properties, Century entered into a consulting agreement, dated
August 14, 1998, with LEC Consulting Corporation, a corporation owned and
operated by current and former members of our management team. Pursuant to the
consulting agreement, LEC Consulting provided management and advisory services
to Century's Alaska properties with respect to its day-to-day business
operations. Under the terms of the consulting agreement, Century paid LEC
Consulting $175,000 per month for these services. In addition to the services
required under the consulting agreement, LEC Consulting employees were
responsible for managing the transition process for us and for creating the
infrastructure necessary to begin operations as of May 14, 1999. In addition,
Fox Paine & Company loaned to LEC Consulting approximately $3.4 million
beginning in August 1998 for funding of start-up expenses, which amount was
repaid out of funds provided by us on May 14, 1999 as part of the fees and
expenses related to the acquisitions of Century's Alaska properties and ATU. LEC
Consulting was merged into Alaska Communications Systems Holdings on May 10,
1999.

    Pursuant to a consulting agreement between Century and Mr. Robinson,
Mr. Robinson will continue to provide consulting services to Century with
respect to its operations in Alaska and the lower 48 states. We do not believe
that these services will interfere with Mr. Robinson's fulfillment of his duties
and responsibilities to us. We have agreed that Mr. Robinson will not
participate in making any decisions relating to acquisitions by us in the lower
48 states during the term of his consulting agreement and for two years
thereafter. This consulting agreement will expire on or before November 2000.


    In connection with the completion of the acquisitions of Century's Alaska
properties and ATU, members of management were given grants of our common stock.
In connection with the stock grants, we loaned Messrs. Robinson and Carson
approximately 40% of the fair market value of the grants on May 14, 1999 on a
nonrecourse basis. Subsequently, we loaned Mr. Wonnell approximately 40% of the
fair market value of the grants on July 31, 1999 on a nonrecourse basis. The
proceeds of these loans, which are secured by the shares of our common stock
owned by the individual borrowers, were to be used by those three individuals to
pay taxes on the income deemed received in connection with the grants.



    Fox Paine & Company received aggregate advisory fees in the amount of
$14.2 million upon consummation of the acquisitions of Century's Alaska
properties and ATU. In addition, Fox Paine & Company will receive an annual
management fee in the amount of 1% of Alaska Communications Systems Group's net
income before interest expense, interest income, income taxes, depreciation and
amortization and equity in earnings (losses) of minority investments, calculated
without regard to the fee.

          SECURITY OWNERSHIP BY MANAGEMENT AND PRINCIPAL STOCKHOLDERS

    The following table sets forth certain information with respect to
beneficial ownership of common stock, including the percent of the total voting
power, as of the date of this prospectus, and as adjusted to reflect completion
of the offerings, by

    - each of our five most highly compensated officers,

    - each director,

    - each holder of more than 5% of our common stock and

    - all current directors and executive officers as a group.

    Except as otherwise indicated in the footnotes below, each beneficial owner
has the sole power to vote and to dispose of all shares held by that holder. You
should keep the following points in mind as you read the information in the
table.

    - The amounts and percentage of our common stock beneficially owned by a
      holder are reported on the basis of the regulations of the SEC that govern
      the determination of beneficial ownership of securities. Under these
      regulations, a person is deemed to be a "beneficial owner" of a security
      if that person has or shares "voting power", which includes the power to
      vote or to direct the voting of the security, or "investment power", which
      includes the power to dispose of or to direct the disposition of the
      security. A person is also deemed to be a beneficial owner of any
      securities with respect to which that person has a right to acquire
      beneficial ownership within 60 days. Under these rules, more than one
      person may be deemed a beneficial owner of the same security and a person
      may be deemed to be a beneficial owner of securities as to which that
      person has no economic interest.


    - The percentage of our common stock outstanding is based on the 21,829,273
      shares of our common stock outstanding as of the date of this prospectus,
      without taking into account any options or convertible interests.



    - We have computed percentages of shares outstanding with respect to the
      currently outstanding shares of our common stock held by the holder,
      without taking into account any options in calculating beneficial
      ownership of common stock before the offering, and taking into account
      options which vest upon completion of the offering in calculating
      beneficial ownership of common stock after the offering.

                          DESCRIPTION OF INDEBTEDNESS

THE SENIOR CREDIT FACILITY


    Alaska Communications Systems Holdings, together with us, entered into a
credit agreement with The Chase Manhattan Bank, as administrative agent and
collateral agent, Credit Suisse First Boston Corporation, as documentation
agent, and Canadian Imperial Bank of Commerce, as syndication agent, and the
lenders named therein that provides the Alaska Communications Systems Holdings'
senior credit facility consisting of term loans of up to $460.0 million and a
revolving credit facility of $75.0 million. Chase Securities Inc. acted as
advisor and arranger in connection with the senior credit facility. The
following is a summary description of the material terms of the senior credit
facility, as amended as of October 19, 1999, and is subject to and qualified in
its entirety by reference to the credit agreement, which has been filed as an
exhibit to the registration statement of which this prospectus is a part.


    STRUCTURE.  Loans under the credit agreement consist of:

    - a term loan A facility in the amount of $150.0 million;

    - a term loan B facility in the amount of $150.0 million;

    - a term loan C facility in the amount of $160.0 million; and

    - a revolving credit facility in the amount of $75.0 million which is
      available, in part, for up to $25.0 million in letters of credit and up to
      $10.0 million in the form of swingline loans.

The term loan facilities and the revolving credit facility constitute the senior
credit facility. Alaska Communications Systems Holdings used the term loan
facilities and a portion of the revolving credit facility to provide a portion
of the funds necessary to complete the acquisitions of Century's Alaska
properties and ATU and to repay existing indebtedness of Century's Alaska
properties. Alaska Communications Systems Holdings will use the remainder of the
revolving credit facility for general corporate purposes.

    SECURITY; GUARANTEES.  Alaska Communications Systems Holdings' obligations
under the senior credit facility are unconditionally and irrevocably guaranteed,
jointly and severally, by us and by each of Alaska Communications Systems
Holdings' existing and subsequently acquired or organized domestic or, in
limited circumstances, foreign subsidiaries. In addition, the senior credit
facility and the related guarantees are secured by collateral that includes
substantially all of Alaska Communications Systems Holdings' assets and all of
the assets of Alaska Communications Systems Holdings' subsidiaries, including:

    - a first priority pledge:

       -   by us of all of Alaska Communications Systems Holdings' capital stock
           and

       -   to the extent not prohibited by law or any existing contract, by
           Alaska Communications Systems Holdings of the capital stock of
           companies in which Alaska Communications Systems Holdings holds a
           minority stake, plus of all the capital stock of Alaska
           Communications Systems Holdings, or any of its domestic subsidiaries
           or, under limited circumstances, any of Alaska Communications Systems
           Holdings' foreign subsidiaries, held in any existing and subsequently
           acquired or organized subsidiary, which pledge, in the case of any
           foreign subsidiary will, except under limited circumstances, be
           limited to 65% of the capital stock of the foreign subsidiary, and

                                       97
<PAGE>
    - a perfected first priority security interest in, and mortgage on,
      substantially all of Alaska Communications Systems Holdings' tangible and
      intangible assets and substantially all of the tangible and intangible
      assets of the guarantors, including accounts receivable, documents,
      inventory, equipment, intellectual property, investment property, general
      intangibles, real property, cash and cash accounts and proceeds of the
      foregoing, in each case subject to limited exceptions.

The credit agreement provides for the release of guarantees under limited
circumstances.

    AVAILABILITY.  The availability of the senior credit facility is subject to
various conditions precedent typical of bank loans including, among other
things, the absence of any material adverse change in Alaska Communications
Systems Holdings' business. The full amount of the term loan facilities was
drawn as required in a single drawing on May 14, 1999. As a result of issuance
of $150.0 million in Alaska Communications Systems Holdings senior subordinated
notes, the term loan C facility was reduced to $135.0 million on May 14, 1999.
Amounts repaid or prepaid under the term loan facilities may not be reborrowed.
Amounts repaid under the revolving credit facility are available for reborrowing
on a revolving basis, subject to the terms of the revolving credit facility.

    AMORTIZATION AND INTEREST

    - The term loan A facility is repayable in annual principal payments of
      1.00% of outstanding principal over five years, commencing on May 14,
      2002, with the balance of the term loan A facility payable at maturity.
      The final maturity of the term loan A facility is November 14, 2006. The
      term loan A facility bears interest at an annual rate equal (at Alaska
      Communications Systems Holdings' option) to: (1) an adjusted London
      interbank offered rate, or LIBOR, plus 2.75% or (2) a rate equal to 1.75%
      plus the greater of the administrative agent's prime rate, a certificate
      of deposit rate plus 1.00% and the federal funds effective rate plus
      0.50%, in each case subject to reduction based on Alaska Communications
      Systems Holdings' financial performance.

    - The term loan B facility is repayable in annual principal payments of
      1.00% of outstanding principal over six years, commencing on May 14, 2002,
      with the balance of term loan B facility payable at maturity. The final
      maturity of the term loan B facility is November 14, 2007. The term loan B
      facility bears interest at an annual rate equal (at Alaska Communications
      Systems Holdings' option) to: (1) an adjusted LIBOR plus 3.00% or (2) a
      rate equal to 2.00% plus the greater of the administrative agent's prime
      rate, a certificate of deposit rate plus 1.00% and the federal funds
      effective rate plus 0.50%.

    - The term loan C facility is repayable in annual principal payments of
      1.00% of outstanding principal over six years, commencing on May 14, 2002,
      with the balance of term loan C facility payable at maturity. The final
      maturity of the term loan C facility is May 14, 2008. The term loan C
      facility bears interest at an annual rate equal (at Alaska Communications
      Systems Holdings' option) to: (1) an adjusted LIBOR plus 3.25% or (2) a
      rate equal to 2.25% plus the greater of the administrative agent's prime
      rate, a certificate of deposit rate plus 1.00% and the federal funds
      effective rate plus 0.50%.

    - The revolving credit facility is a seven-year facility and outstanding
      balances thereunder will bear interest at an annual rate equal (at Alaska
      Communications Systems Holdings' option) to: (1) an adjusted LIBOR plus
      2.75% or (2) a rate equal to 1.75% plus the greater of the administrative
      agent's prime rate, a certificate of deposit rate plus 1.00% and the
      federal funds effective rate plus 0.50%, in each case subject to reduction
      based on Alaska Communications Systems Holdings' financial performance.

                                       98
<PAGE>
Amounts under the senior credit facility not paid when due bear interest at a
default rate equal to 2.00% above the otherwise applicable rate.

    On July 24, 1999 we entered into a hedging transaction which fixed at 5.99%
the underlying variable rate on one-half of the borrowings under the senior
credit facility, or $217.5 million, for a three-year period.

    PREPAYMENTS.  The senior credit facility permits Alaska Communications
Systems Holdings to prepay loans and to permanently reduce revolving credit
commitments, in whole or in part, at any time. In addition, Alaska
Communications Systems Holdings is required to make mandatory prepayments of the
term loan facilities, subject to limited exceptions, in amounts equal to the
excess, if any, of:

    - 50% of excess cash flow for each fiscal year, as specified in the credit
      agreement, over

    - the aggregate principal amount of the term loan facilities prepaid during
      the fiscal year.

Alaska Communications Systems Holdings is also required to make mandatory
prepayments of term loan facilities, subject to limited exceptions, with the net
cash proceeds of dispositions of assets or issuances of debt of us or any of our
subsidiaries. Mandatory and optional prepayments will be allocated ratably among
the term loan A facility, the term loan B facility and the term loan C facility,
as applicable, and within each term loan facility, applied ratably to the
remaining amortization payments under that facility, except that the lenders
participating in the term loan B facility and the term loan C facility, as
applicable, have the right to refuse mandatory prepayments, in which case those
prepayments will be applied to the term loan A facility, or, if no portion of
the term loan A facility remains outstanding, Alaska Communications Systems
Holdings may retain the prepayments. Any prepayment of adjusted LIBOR loans
other than at the end of an interest period will be subject to reimbursement of
breakage costs as described in the credit agreement.

    FEES.  Alaska Communications Systems Holdings is required to pay the
lenders, on a quarterly basis, a commitment fee equal to 0.50% annually on the
undrawn portion of the unused commitments, subject to reductions based upon
Alaska Communications Systems Holdings' financial performance. Alaska
Communications Systems Holdings is also required to pay:

    - on a quarterly basis, a commission on the face amount of all outstanding
      letters of credit equal to the applicable margin then in effect for
      adjusted LIBOR loans under the revolving credit facility,

    - on a quarterly basis, a fronting fee in the amount of 0.25% annually on
      each letter of credit to the issuing bank,

    - standard fees of the issuing bank with respect to issuance, amendment,
      renewal or extension of any letters of credit and

    - fees payable to the administrative agent.


    COVENANTS, EVENTS OF DEFAULT.  The credit agreement contains customary
covenants that, among other things, restrict our ability, the ability of Alaska
Communications Systems Holdings and the ability of Alaska Communications Systems
Holdings' subsidiaries to dispose of assets, incur additional indebtedness,
incur guarantee obligations, prepay other indebtedness or amend other debt
instruments, pay dividends, create liens on assets, enter into sale and
leaseback transactions, make investments, loans or advances, make acquisitions,
engage in mergers or consolidations, change Alaska Communications Systems
Holdings' business, make capital expenditures or engage in transactions with
affiliates. In addition, under the senior credit facility, Alaska Communications


                                       99
<PAGE>

Systems Holdings is required to comply with specified financial ratios,
including minimum interest coverage ratios and maximum leverage ratios. As
discussed below, certain of these restrictions have been modified pursuant to an
amendment dated as of October 19, 1999, which is conditioned upon receipt of
gross proceeds from the offering of not less than $140,000,000.


    The credit agreement also contains provisions that prohibit any modification
of the indenture relating to the senior subordinated notes of Alaska
Communications Systems Holdings as well as customary representations and
warranties, affirmative covenants and events of default, including cross
default, material judgments and change in control.


    As of October 19, 1999 and subject to receiving gross proceeds from the
offering of not less than $140 million and contributing the net proceeds (other
than such amounts permitted to be used for the repayment of our senior discount
debentures) from the offering to Alaska Communications Systems Holdings as
common equity, and the satisfaction of other customary conditions to
effectiveness, we have amended the credit agreement related to the senior credit
facility. The amendment:



    - modifies the provisions related to the prepayment of indebtedness to
      permit the payment of up to $40.0 million for the repurchase of our senior
      discount debentures and/or the Alaska Communications Systems Holdings
      senior subordinated notes under certain circumstances;



    - modifies the provisions related to capital expenditures to increase the
      amount of capital expenditures we are permitted to make in each year;



    - increases our flexibility with respect to acquisitions and other
      investments, allowing for "permitted acquisitions" of up to
      $200.0 million, which amount excludes acquisitions made using our capital
      stock or equity contributions from Fox Paine, and "permitted investments"
      of up to $15.0 million; and



    - increases our flexibility with respect to the incurrence of certain
      indebtedness.



    If we receive less than $140 million in gross proceeds from the offering,
the amendment will not become effective. In that event, we intend to seek a new
amendment providing for all or a portion of the flexibility currently
contemplated.



    If the lenders under the credit agreement do not consent to that new
amendment, we will not be permitted under the credit agreement to redeem any of
our senior discount debentures. Additionally, while we will continue to use
available proceeds to reduce the outstanding balance under our revolving credit
facility and for general corporate purposes, including acquisitions, our
flexibility to pursue strategic investments or acquisitions will be limited to
the extent currently provided in the credit agreement. In such event, we will
also be required to adjust our planned capital expenditures to satisfy covenants
contained in the credit agreement.


THE ALASKA COMMUNICATIONS SYSTEMS HOLDINGS SENIOR SUBORDINATED NOTES


    On May 14, 1999, Alaska Communications Systems Holdings issued
$150.0 million in aggregate principal amount of senior subordinated notes due
2009 in a private transaction not subject to the registration requirements of
the Securities Act. Cash interest is payable on the outstanding principal amount
of the senior subordinated notes at the annual rate of 9 3/8% payable
semiannually on May 15th and November 15th of each year, commencing
November 15, 1999, subject to restrictions on dividends to Alaska Communications
Systems Holdings contained in the senior credit facility. On October 8, 1999, a
registration statement on Form S-4 relating to a registered exchange offer for
the senior subordinated notes was declared effective by the SEC.


                                      100
<PAGE>

Holders of the senior subordinated notes will be able to exchange their notes
for registered senior subordinated notes in the exchange offer.


    The senior subordinated notes rank junior in right of payment to all current
and future senior indebtedness of Alaska Communications Systems Holdings, rank
equally in right of payment to all current and future senior subordinated
indebtedness of Alaska Communications Systems Holdings and rank senior in right
of payment to all current and future subordinated indebtedness of Alaska
Communications Systems Holdings. As obligations of a holding company, the senior
subordinated notes are effectively subordinated to all obligations of the
subsidiaries of Alaska Communications Systems Holdings.

    The senior subordinated notes are not redeemable until May 15, 2004.
Thereafter, the senior subordinated notes will be redeemable at the option of
Alaska Communications Systems Holdings with a premium that declines each year
until 2007, when the senior subordinated notes will be redeemable in whole or in
part at 100% of their principal amount plus accrued and unpaid interest. Upon a
change of control as described in the indenture governing the senior
subordinated notes, each holder will be able to require Alaska Communications
Systems Holdings to offer to redeem the holder's senior subordinated notes at a
price equal to 101% of principal amount, subject to restrictions contained in
the senior credit facility. If Alaska Communications Systems Holdings
consummates one or more offerings of Alaska Communications Systems Holdings
capital stock on or before May 15, 2002, Alaska Communications Systems Holdings,
at its option, will be able to use all or a portion of the sale proceeds to
redeem up to 35% of the aggregate principal amount of the senior subordinated
notes originally issued, at a price equal to their principal amount plus a
premium equal to one year's interest at the stated interest rate.

    The indenture relating to the senior subordinated notes contains various
restrictive covenants that, among other things, limit:

    - the incurrence of indebtedness by Alaska Communications Systems Holdings
      and its subsidiaries,

    - the payment of restricted payments, as described in the indenture relating
      to the senior subordinated notes,

    - the payment of dividends on stock and purchases of stock,

    - the sale of assets or stock of Alaska Communications Systems Holdings'
      subsidiaries,

    - transactions with affiliates,

    - mergers, consolidations and sales of assets and

    - the business activities in which Alaska Communications Systems Holdings
      and its subsidiaries may engage.

The indenture also limits the extent to which Alaska Communications Systems
Holdings may permit restrictions on the ability of its subsidiaries to pay
dividends and make other distributions. Each of these limitations, however, is
subject to qualifications set forth fully in the indenture governing the senior
subordinated notes, which has been filed as an exhibit to the registration
statement of which this prospectus is a part.

    The indenture relating to the senior subordinated notes also contains events
of default customary for obligations of this type, including:

    - a default in the payment of interest on the senior subordinated notes when
      due and payable,

                                      101
<PAGE>
    - the acceleration of debt of Alaska Communications Systems Holdings or any
      of its subsidiaries in an amount in excess of $5.0 million and

    - the rendering of any judgment for the payment of money in excess of
      $5.0 million against Alaska Communications Systems Holdings

subject, in each case, to applicable grace periods.

    Payment of all amounts outstanding under the senior subordinated notes could
be accelerated in the event of a default under the indenture governing the
senior subordinated notes.


THE ALASKA COMMUNICATIONS SYSTEMS GROUP DISCOUNT DEBENTURES



    On May 14, 1999, we issued $46.9 million in aggregate principal amount of
senior discount debentures due 2011 and 828,261 warrants, for gross proceeds of
$25.0 million, in a private transaction not subject to the registration
requirements of the Securities Act. No cash interest is payable on the discount
debentures for five years following issuance, but deferred interest accrues at
the annual rate of 13%. On and after May 15, 2004, cash interest will be payable
on the outstanding principal amount of the discount debentures, including
accrued deferred interest, at the annual rate of 13% payable semiannually on
May 15th and November 15th of each year, subject to restrictions on dividends to
us contained in the senior credit facility and the indenture relating to the
senior subordinated notes. On October 8, 1999 a registration statement on Form
S-4 relating to a registered exchange offer for the senior discount debentures
was declared effective by the SEC. Holders of the discount debentures will be
able to exchange their debentures for registered discount debentures in the
exchange offer. On October 29, 1999 we amended the indenture resulting to the
discount debentures to provide for optional cash interest payments by Alaska
Communications Systems Group prior to May 15, 2004. The amendment is subject to
the offering being completed prior to March 31, 2000, and the amendment to the
credit agreement described under "--The Senior Credit Facility" becoming
effective.


    The discount debentures rank equally in right of payment to all of our
current and future senior indebtedness and rank senior in right of payment to
all of our current and future subordinated indebtedness. As obligations of a
holding company, the discount debentures are effectively subordinated to all
obligations of our subsidiaries, including Alaska Communications Systems
Holdings' obligations under the senior subordinated notes and borrowings under
the senior credit facility.

    The discount debentures are not redeemable until May 15, 2004. Thereafter,
the discount debentures will be redeemable at our option with a premium that
declines each year until 2009, when the discount debentures will be redeemable
in whole or in part at 100% of their principal amount plus accrued and unpaid
interest. Upon a change of control as described in the indenture governing the
discount debentures, each holder will be able to require us to offer to redeem
the holder's discount debentures at a price equal to 101% of accreted value or,
if after May 15, 2004, of the principal amount thereof plus accrued and unpaid
interest thereon, subject to restrictions contained in the senior credit
facility and the indenture relating to the senior subordinated notes. If we
consummate one or more offerings of our common stock on or before May 15, 2002,
we, at our option, will be able to use all or a portion of the sale proceeds to
redeem up to 35% of the aggregate principal amount of the discount debentures
originally issued, at a price equal to their accreted value plus a premium equal
to one year's interest at the stated interest rate. As more fully described
under "Use of Proceeds", we intend to use $10.5 of the net proceeds from the
offerings to repay $9.3 million in aggregate accreted value of the senior
discount debentures, plus a redemption premium of $1.2 million.

                                      102
<PAGE>
    The indenture relating to the discount debentures contains various
restrictive covenants that, among other things, limit:

    - the incurrence of indebtedness by us and our subsidiaries,

    - the payment of restricted payments, as described in the indenture relating
      to the discount debentures,

    - the payment of dividends on stock and purchases of stock,

    - the sale of assets or stock of our subsidiaries,

    - transactions with affiliates,

    - mergers, consolidations and sales of assets and

    - the business activities in which we and our subsidiaries may engage.

Each of these limitations, however, is subject to qualifications set forth fully
in the indenture governing the senior discount debentures, which has been filed
as an exhibit to the registration statement of which this prospectus is a part.

    The indenture relating to the discount debentures also contains events of
default customary for obligations of this type, including:

    - a default in the payment of interest on the discount debentures when due

                          DESCRIPTION OF CAPITAL STOCK

    THE FOLLOWING SUMMARY DESCRIBES THE MATERIAL TERMS OF OUR CAPITAL STOCK.
HOWEVER, YOU SHOULD REFER TO THE ACTUAL TERMS OF THE CAPITAL STOCK CONTAINED IN
OUR CERTIFICATE OF INCORPORATION AND IN OTHER AGREEMENTS REFERENCED BELOW.


    Our authorized capital stock consists of 40 million shares of common stock,
par value $0.01 per share, and currently no shares of preferred stock. We intend
to amend our charter to authorize 145,000,000 shares of common stock and
5,000,000 shares of preferred stock. We currently have 21,829,273 shares of
common stock outstanding. After this offering, there will be 31,829,273 shares
of common stock outstanding, without giving effect to the exercise of the
underwriters' over-allotment option.


COMMON STOCK

    Subject to the rights of the holders of any preferred stock that may be
outstanding, each holder of common stock on the applicable record date is
entitled to receive dividends as may be declared by our board of directors out
of funds legally available to pay dividends, and, in the event of liquidation,
to share ratably in any distribution of our assets after payment or providing
for the payment of liabilities and the liquidation preference of any outstanding
preferred stock. Common stock will vote together as a single class on all
matters presented to a vote of stockholders, including the election of
directors. Each holder of common stock is entitled to one vote for each share
held of record on the applicable record date for all of these matters. Holders
of common stock have no cumulative voting rights or preemptive rights to
purchase or subscribe for any stock or other securities, and there are no
conversion rights or redemption or sinking fund provisions with respect to
common stock. All outstanding shares of common stock are, and the shares of
common stock sold in the offerings will be when issued, fully paid and
nonassessable.

PREFERRED STOCK


    We intend to amend our charter to authorize 5,000,000 shares of preferred
stock and give our board of directors the authority to issue shares of preferred
stock in one or more series and to fix, by resolution, the voting powers, and
designations, preferences and relative, participating, optional or other rights,
if any, and the qualifications, limitations or restrictions thereof, if any,
including the number of shares in each series (which our board of directors may
increase or decrease as permitted by Delaware law), liquidation preferences,
dividend rates, conversion rights and redemption provisions of the shares
constituting any series, without any further vote or action by the stockholders.
Any shares of preferred stock so issued would have priority over the common
stock with respect to dividend or liquidation rights or both. Although our board
of directors has no present plans to do so, it could issue one or more series of
preferred stock, without stockholder approval, that could, depending on the
terms of such series, impede the completion of a merger, tender offer or other
takeover attempt.


DELAWARE GENERAL CORPORATION LAW

    Section 203 of the Delaware General Corporation Law generally prevents
Delaware corporations from engaging under certain circumstances in a business
combination with any interested stockholder for three years following the date
that the stockholder became an interested stockholder. We intend to opt out of
the provisions of Section 203.

ACTION BY WRITTEN CONSENT


    Under the Delaware General Corporation Law, unless the certificate of
incorporation expressly prohibits action by the written consent for
stockholders, any action required or permitted to be


                                      104
<PAGE>

taken by our stockholders at a duly called annual or special meeting of
stockholders may be taken by a consent in writing executed by stockholders
possessing the requisite votes for the action to be taken. Our certificate of
incorporation does not expressly prohibit action by the written consent of
stockholders. As a result, Fox Paine & Company, as holder of 61.4% of our total
voting power after this offering, will be able to take any action to be taken by
stockholders without the necessity of holding a stockholder meeting. We intend,
however, to hold annual meetings of stockholders.


TRANSFER AGENT AND REGISTRAR


    The transfer agent and registrar for the common stock will be ChaseMellon
Shareholder Services, L.L.C.


LISTING


    Application has been made for quotation of our common stock on the Nasdaq
National Market under the symbol "ALSK".


                                      105
<PAGE>
                        SHARES ELIGIBLE FOR FUTURE SALE


    Prior to the offering, there has been no public market for our common stock.
Future sales of substantial amounts of common stock in the public market, or the
perception that substantial sales may occur, could adversely affect the
prevailing market price of the common stock. After completion of the offering,
there will be 31,829,273 shares of common stock outstanding. Of these shares,
the 10,000,000 shares of common stock sold in the offering, or 11,500,000 shares
if the underwriter's options to purchase additional shares are exercised in
full, will be freely transferable without restriction under the Securities Act,
except by persons who may be deemed to be our affiliates. All the remaining
shares of common stock may not be sold unless they are registered under the
Securities Act or are sold pursuant to an exemption from registration, including
an exemption contained in Rule 144 under the Securities Act.


    In general, under Rule 144 as currently in effect, a person, or persons
whose shares are aggregated, including an affiliate, who beneficially owns
"restricted securities" may not sell those securities until they have been
beneficially owned for at least one year. Thereafter, the person would be
entitled to sell within any three-month period a number of shares that does not
exceed the greater of:

    (1) 1% of the then outstanding shares of common stock, or approximately
                    shares after the offering; and

    (2) the average weekly trading volume of the common stock on the Nasdaq
       National Market during the four calendar weeks preceding the date on
       which notice of the sale is filed with the SEC.

Sales under Rule 144 are subject to certain restrictions relating to manner of
sale, notice and the availability of current public information about us and may
be effected only through unsolicited brokers' transactions.

    A person who is not deemed an "affiliate" of us at any time during the
90 days preceding a sale would (but for the Stockholders' Agreement described
above and the "lock-up" arrangements described below) be entitled to sell his,
her or its restricted shares under Rule 144 without regard to the volume or
other limitations described above, once two years have elapsed since the
restricted shares were acquired from us or one of our affiliates.


    We, our directors, executive officers and our principal stockholders have
agreed with the underwriters that, during the period beginning from the date of
this prospectus and continuing to and including the date 180 days after the date
of this prospectus, we will not offer, sell, contract to sell or otherwise
dispose of any shares of common stock or any securities of Alaska Communications
Systems Group which are substantially similar to the shares of the common stock
or which are convertible into or exchangeable for securities which are
substantially similar to the shares of common stock (other than, in our case,
pursuant to our existing employee compensation plans) without the prior written
consent of Goldman, Sachs & Co., except for the shares of common stock offered
in connection with the offerings. The lock-up agreements by these persons (other
than Alaska Communications Systems Group) cover an aggregate of approximately
21,651,000 shares.


    No prediction can be made as to the effect, if any, that market sales of
restricted shares or the availability of restricted shares for sale will have on
the market price of our common stock prevailing from time to time. Nevertheless,
sales of substantial amounts of common stock, or the perception that such sales
could occur, could adversely affect prevailing market prices for our common
stock and could impair our future ability to raise capital through an offering
of our equity securities, as described under "Risk Factors--Our share price may
decline due to the large number of shares eligible for future sale".

                                      106
<PAGE>

    In connection with the offering, we intend to file a registration statement
on Form S-8 to register 6,060,486 shares of common stock that are or will be
reserved for issuance or sale under our stock incentive, non-employee director
compensation and stock purchase plans. As of October 29, 1999, there were
outstanding options to purchase a total of 3,332,000 shares of common stock of
which 20,000 options were vested. In addition, options to purchase an additional
1,127,750 shares of common stock that have been granted to our employees will
vest upon completion of the offering. These employees have agreed not to dispose
of more than 20% of the shares they may receive upon exercise of these options
before each anniversary following the date of grant of the options (plus any
shares permitted to be disposed of, but not disposed of, in any previous year).
All of such shares of common stock issuable upon exercise of options under our
stock incentive, non-employee director compensation and stock purchase plans
would otherwise be freely tradable upon effectiveness of the registration
statement without restrictions under the Securities Act of 1933, unless such
shares are held by an "affiliate" of us.

                   U.S. TAX CONSEQUENCES TO NON-U.S. HOLDERS

    The following is a general discussion of the principal U.S. federal income
and estate tax consequences of the ownership and disposition of our common stock
by a non-U.S. holder. As used in this prospectus, the term "non-U.S. holder" is
a person other than:

    - a citizen or individual resident of the U.S. for U.S. federal income tax
      purposes,

    - a corporation or other entity taxable as a corporation created or
      organized in or under the laws of the United States or of any political
      subdivision of the U.S.,

    - an estate whose income is includible in gross income for U.S. federal
      income tax purposes regardless of its source or

    - a trust, in general, if it is subject to the primary supervision of a
      court within the U.S. and the control of one or more U.S. persons.

    This discussion does not consider:

    - U.S. state and local or non-U.S. tax consequences,

    - specific facts and circumstances that may be relevant to a particular
      non-U.S. holder's tax position, including, if the non-U.S. holder is a
      partnership, that the U.S. tax consequences of holding and disposing of
      our common stock may be affected by certain determinations made at the
      partner level,

    - the tax consequences for the shareholders or beneficiaries of a non-U.S.
      holder,

    - special tax rules that may apply to certain non-U.S. holders, including
      without limitation, banks, insurance companies, dealers in securities and
      traders in securities who elect to apply a mark-to-market method of
      accounting or

    - special tax rules that may apply to a non-U.S. holder that holds our
      common stock as part of a "straddle," "hedge" or "conversion transaction".

    The following is based on provisions of the U.S. Internal Revenue Code of
1986, as amended, applicable Treasury regulations, and administrative and
judicial interpretations, all as of the date of this prospectus, and all of
which may change, retroactively or prospectively. The following summary is for
general information. ACCORDINGLY, EACH NON-U.S. HOLDER SHOULD CONSULT A TAX
ADVISOR REGARDING THE U.S. FEDERAL, STATE, LOCAL AND NON-U.S. INCOME AND OTHER
TAX CONSEQUENCES OF ACQUIRING, HOLDING AND DISPOSING OF SHARES OF OUR COMMON
STOCK.

DIVIDENDS

    In the event that dividends are paid on shares of common stock, dividends
paid to a non-U.S. holder of common stock generally will be subject to
withholding of U.S. federal income tax at a 30% rate, or such lower rate as may
be provided by an applicable income tax treaty. Non-U.S. holders should consult
their tax advisors regarding their entitlement to benefits under a relevant
income tax treaty.

    Dividends that are effectively connected with a non-U.S. holder's conduct of
a trade or business in the U.S. or, if an income tax treaty applies,
attributable to a permanent establishment, or in the case of an individual, a
"fixed base", in the U.S., as provided in that treaty ("U.S. trade or business
income"), are generally subject to U.S. federal income tax on a net income basis
at regular graduated rates, but are not generally subject to the 30% withholding
tax if the non-U.S. holder files the appropriate U.S. Internal Revenue Service
form with the payor. Any U.S. trade or business income received by a non-U.S.
holder that is a corporation may also, under certain

                                      108
<PAGE>
circumstances, be subject to an additional "branch profits tax" at a 30% rate or
such lower rate as specified by an applicable income tax treaty.

    Dividends paid prior to 2001 to an address in a foreign country are
presumed, absent actual knowledge to the contrary, to be paid to a resident of
such country for purposes of the withholding discussed above and for purposes of
determining the applicability of a tax treaty rate. For dividends paid after
2000:

    - a non-U.S. holder of common stock who claims the benefit of an applicable
      income tax treaty rate generally will be required to satisfy applicable
      certification and other requirements;

    - in the case of common stock held by a foreign partnership, the
      certification requirement will generally be applied to the partners of the
      partnership and the partnership will be required to provide certain
      information, including a U.S. taxpayer identification number and

    - look-through rules will apply for tiered partnerships.

    A non-U.S. holder of common stock that is eligible for a reduced rate of
U.S. withholding tax under an income tax treaty may obtain a refund or credit of
any excess amounts withheld by filing an appropriate claim for a refund with the
IRS.

GAIN ON DISPOSITION OF COMMON STOCK

    A non-U.S. holder generally will not be subject to U.S. federal income tax
in respect of gain recognized on a disposition of common stock unless:

    - the gain is U.S. trade or business income, in which case, the branch
      profits tax described above may also apply to a corporate non-U.S. holder,

    - the non-U.S. holder is an individual who holds the common stock as a
      capital asset within the meaning of Section 1221 of the Internal Revenue
      Code, is present in the U.S. for more than 182 days in the taxable year of
      the disposition and meets certain other requirements,

    - the non-U.S. holder is subject to tax pursuant to the provisions of the
      U.S. tax law applicable to certain U.S. expatriates or

    - we are or have been a "U.S. real property holding corporation" for federal
      income tax purposes at any time during the shorter of the five-year period
      ending on the date of disposition or the period that the non-U.S. holder
      held our common stock.


    Generally, a corporation is a "U.S. real property holding corporation" if
the fair market value of its "U.S. real property interests" equals or exceeds
50% of the sum of the fair market value of its worldwide real property interests
plus its other assets used or held for use in a trade or business. We believe
that Alaska Communications Systems Group has not been and is not currently, and
we do not anticipate it becoming, a "U.S. real property holding corporation" for
U.S. federal income tax purposes. The tax relating to stock in a "U.S. real
property holding corporation" will not apply to a non-U.S. holder whose
holdings, direct and indirect, at all times during the applicable period,
constituted 5% or less of the common stock, provided that the common stock was
regularly traded on an established securities market.


FEDERAL ESTATE TAX

    Common stock owned or treated as owned by an individual who is a non-U.S.
holder at the time of death will be included in the individual's gross estate
for U.S. federal estate tax purposes, unless an applicable estate tax or other
treaty provides otherwise and, therefore, may be subject to U.S. federal estate
tax.

                                      109

INFORMATION REPORTING AND BACKUP WITHHOLDING TAX

    Under certain circumstances, U.S. Treasury Regulations require information
reporting and backup withholding at a rate of 31% on certain payments on common
stock. Under currently applicable law, non-U.S. holders of common stock
generally will be exempt from these information reporting requirements and from
backup withholding on dividends paid prior to 2001 to an address outside the
U.S. For dividends paid after 2000, however, a non-U.S. holder of common stock
that fails to certify its non-U.S. holder status in accordance with applicable
U.S. Treasury Regulations may be subject to backup withholding at a rate of 31%
on payments of dividends.

    The payment of the proceeds of the disposition of common stock by a holder
to or through the U.S. office of a broker or through a non-U.S. branch of a U.S.
broker generally will be subject to information reporting and backup withholding
at a rate of 31% unless the holder either certifies its status as a non-U.S.
holder under penalties of perjury or otherwise establishes an exemption. The
payment of the proceeds of the disposition by a non-U.S. holder of common stock
to or through a non-U.S. office of a non-U.S. broker will not be subject to
backup withholding or information reporting unless the non-U.S. broker is a
"U.S. related person". In the case of the payment of proceeds from the
disposition of common stock by or through a non-U.S. office of a broker that is
a U.S. person or a "U.S. related person", information reporting, but currently
not backup withholding, on the payment applies unless the broker receives a
statement from the owner, signed under penalty of perjury, certifying its
non-U.S. status or the broker has documentary evidence in its files that the
holder is a non-U.S. holder and the broker has no actual knowledge to the
contrary. For this purpose, a "U.S. related person" is:

    - a "controlled foreign corporation" for U.S. federal income tax purposes,

    - a foreign person 50% or more of whose gross income for certain periods is
      derived from the conduct of a U.S. trade or business or

    - effective after 2000, a foreign partnership if, at any time during its
      taxable year, (A) at least 50% of the capital or profits interest in the
      partnership is owned by U.S. persons, or (B) the partnership is engaged in
      a U.S. trade or business.

    Effective after 2000, backup withholding may apply to the payment of
disposition proceeds by or through a non-U.S. office of a broker that is a U.S.
person or a "U.S. related person" unless certain certification requirements are
satisfied or an exemption is otherwise established and the broker has no actual
knowledge or reason to know that the holder is a U.S. person. Non-U.S. holders
should consult their own tax advisors regarding the application of the
information reporting and backup withholding rules to them, including changes to
these rules that will become effective after 2000.

    Any amounts withheld under the backup withholding rules from a payment to a
non-U.S. holder will be refunded, or credited against the holder's U.S. federal
income tax liability, if any, provided that the required information is
furnished to the IRS.

                               VALIDITY OF SHARES

    The validity of the shares of common stock will be passed upon for us by
Wachtell, Lipton, Rosen & Katz, New York, New York and for the underwriters by
Cravath, Swaine & Moore, New York, New York.

    Shares sold by the Underwriters to the public will initially be offered at
the initial public offering price set forth on the cover of this prospectus. Any
shares sold by the Underwriters to securities dealers may be sold at a discount
of up to $     per share from the initial public offering price. Any such
securities dealers may resell any shares purchased from the Underwriters to
certain other brokers or dealers at a discount of up to $     per share from the
initial public offering price. If all the shares are not sold at the initial
offering price, the representatives may change the offering price and the other
selling terms.


    Alaska Communications Systems Group has agreed with the Underwriters not to
dispose of or hedge any of their common stock or securities convertible into or
exchangeable for shares of common stock during the period from the date of this
prospectus continuing through the date 180 days after the date of this
prospectus, except with the prior written consent of Goldman, Sachs & Co. This
agreement does not apply to any existing employee benefit plans. See "Shares
Eligible for Future Sale" for a discussion of certain transfer restrictions.



    Prior to the offering, there has been no public market for the shares. The
initial public offering price has been negotiated among Alaska Communications
Systems Group and the representatives. Among the factors to be considered in
determining the initial public offering price of the shares, in addition to
prevailing market conditions, will be Alaska Communications Systems Group's
historical performance, estimates of business potential and earnings prospects
of Alaska Communications Systems Group, an assessment of Alaska Communications
Systems Group's management and the


                                      113

consideration of the above factors in relation to market valuation of companies
in related businesses.



    Application has been made for quotation of the common stock on the Nasdaq
National Market under the symbol "ALSK".


    In connection with the offering, the Underwriters may purchase and sell
shares of common stock in the open market. These transactions may include short
sales, stabilizing transactions and purchases to cover positions created by
short sales. Short sales involve the sale by the Underwriters of a greater
number of shares than they are required to purchase in the offering. Stabilizing
transactions consist of certain bids or purchases made for the purpose of
preventing or retarding a decline in the market price of the common stock while
the offering is in progress.

    The Underwriters also may impose a penalty bid. This occurs when a
particular Underwriter repays to the Underwriters a portion of the underwriting
discount received by it because the representatives have repurchased shares sold
by or for the account of such Underwriter in stabilizing or short covering
transactions.

    These activities by the Underwriters may stabilize, maintain or otherwise
affect the market price of the common stock. As a result, the price of the
common stock may be higher than the price that otherwise might exist in the open
market. If these activities are commenced, they may be discontinued by the
Underwriters at any time. These transactions may be effected on the Nasdaq
National Market, in the over-the-counter market or otherwise.

    The Underwriters do not expect sales to discretionary accounts to exceed
five percent of the total number of shares offered.


    Alaska Communications Systems Group estimates that its share of the total
expenses of the offering, excluding underwriting discounts and commissions, will
be approximately $1.9 million.


    The Underwriters and their affiliates have in the past provided, and may in
the future from time to time provide, investment banking and general financing
and banking services to Fox Paine & Company and its affiliates for which they
have in the past received, and may in the future receive, customary fees.
Affiliates of CIBC World Markets Corp. and affiliates of Deutsche Bank
Securities Inc. are limited partners in certain partnerships organized by Fox
Paine & Company, including certain of the partnerships organized in connection
with the formation of ALEC Holdings.


    Affiliates of Donaldson, Lufkin & Jenrette Securities Corporation were the
initial purchasers of ALEC Holdings' senior discount debentures. These
affiliates of Donaldson, Lufkin & Jenrette Securities Corporation received
warrants to purchase 828,261 shares of common stock at an exercise price of
$0.01 per share in connection with the issuance of the senior discount
debentures. Approximately 828,000 shares underlying these warrants are expected
to be issued in connection with the offering.


    An affiliate of CIBC World Markets Corp., Canadian Imperial Bank of
Commerce, is the syndication agent and a lender under the senior credit facility
and in those capacities receives customary fees, commissions and reimbursement
of expenses. A portion of the net proceeds from the offering will be used to
repay borrowings under the revolving credit facility. CIBC World Markets Corp.
was an initial purchaser of the senior subordinated notes and in that capacity
received customary fees and commissions.

    On September 27, 1999, Hambrecht & Quist Group, the parent corporation of
Hambrecht & Quist, LLP, entered into an agreement and plan of merger with The
Chase Manhattan Corporation pursuant to which Hambrecht & Quist Group and its
subsidiaries will be acquired by The Chase Manhattan Corporation. An affiliate
of The Chase Manhattan Corporation, The Chase Manhattan Bank, is the
administrative agent and collateral agent and a lender under the senior credit
facility and in those capacities receives customary fees, commissions and
reimbursement of expenses. Another affiliate of The Chase Manhattan Corporation,
Chase Securities Inc., was an initial purchaser of the senior subordinated notes
and in that capacity received customary fees and commissions.


    Alaska Communications Systems Group has agreed to indemnify the several
Underwriters against certain liabilities, including liabilities under the
Securities Act of 1933.

                                 MARCH 31, 1999

1.  THE COMPANY


    Alaska Communications Systems Group, Inc. (the "Company")(formerly ALEC
Holdings, Inc.) was incorporated in the State of Delaware in October 1998 to
operate as a holding company to purchase telecommunications properties.


2.  SUBSEQUENT ACQUISITIONS

    At March 31, 1999, Alaska Communications Systems Holdings, Inc. ("ACS"),
which became a wholly owned subsidiary of the Company in May 1999, had announced
two purchase agreements that would allow ACS to enter the telecommunications
industry. The first agreement involved the acquisition of Century Tel's Alaska
holdings including Telephone Utilities of Alaska, Inc., Telephone Utilities of
the Northland, Inc., PTI Communications of Alaska, Inc., Pacific Telecom of
Alaska PCS, Inc. and Pacific Telecom Cellular of Alaska, Inc. The second
agreement was with the Municipality of Anchorage to acquire all of its
telecommunication investments.


    On May 14, 1999, ACS purchased all the outstanding shares of PTI Alaska from
CenturyTel of the Northwest, Inc. and CenturyTel Wireless, Inc., which are
wholly owned subsidiaries of Century. PTI Alaska is the incumbent provider of
local telephone services to over 131,000 access lines in Juneau, Fairbanks and
more than 70 rural communities in Alaska. PTI Alaska also provides cellular
services to approximately 3,000 subscribers and Internet services to
approximately 16,000 customers. The aggregate cash purchase price paid was
approximately $411.8 million.



    On May 14, 1999, ACS also purchased certain of the assets and certain of the
liabilities of the Anchorage Telephone Utility ("ATU") from the Municipality of
Anchorage. ATU is the largest local exchange carrier in Alaska providing local
services to over 168,000 access lines, primarily in Anchorage. ATU also provides
cellular service to over 63,000 subscribers under the MACtel brand name and long
distance service on a resale basis to approximately 26,000 customers. The
aggregate cash purchase price paid was approximately $265.1 million.



    ACS recorded transaction fees and expenses of approximately $48 million from
these purchases. In addition, ACS will amortize approximately $245 million of
acquisition goodwill over 40 years.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES



    The consolidated financial statements for Alaska Communications Systems
Group, Inc. and Subsidiaries (the Company) represent the operating results of
the following four legal entities (see Note 2, Acquisitions):



    Alaska Communications Systems Group, Inc. (formerly ALEC Holdings, Inc.)



    Alaska Communications Systems Holdings, Inc. (formerly ALEC Acquisition
Corporation)



    ALEC Acquisition Sub Corp., Inc. which acquired the stock of the PTI Alaska
companies at the closing of the acquisitions.



    Alaska Communications Systems, Inc. which acquired the stock of ATU Long
Distance, ATU Communications, Inc. and MACtel Inc. on May 14, 1999 and purchased
a majority interest in Alaska Choice Television on September 30, 1999.



    A summary of significant accounting policies followed by the Company is set
forth below:



BASIS OF PRESENTATION



    The accompanying unaudited consolidated financial statements are as of and
for nine months ended September 30, 1999 and include the operations of Alaska
Communications Systems Holdings for the full nine month period and the PTI
Alaska companies, ATU Long Distance, ATU Communications and MACtel since their
acquisition on May 14, 1999. These financial statements have been prepared in
accordance with generally accepted accounting principles for interim financial
information and with the instructions to Form 10-Q and Article 10 of Regulation
S-X. Accordingly, they do not include all of the information and footnotes
required by generally accepted accounting principles for complete financial
statements. In the opinion of management, all adjustments (consisting only of
normal recurring accruals) considered necessary for a fair presentation have
been included. Operating results for the nine month period ended September 30,
1999 are not necessarily indicative of the results that may be expected for the
full fiscal year or for any future period.



USE OF ESTIMATES



    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of commitments and contingencies at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results may differ from those estimates.



REGULATION



    The local telephone exchange activities of the Company are subject to rate
regulation by the Federal Communications Commission (FCC) for interstate
telecommunication service, and the Regulatory Commission of Alaska (RCA) for
intrastate and local exchange telecommunication service. The Company, as
required by the FCC, accounts for such activity separately. Long distance
services are subject to rate regulation as a non-dominant interexchange carrier
by the FCC for

interstate telecommunication services and the RCA for intrastate
telecommunication services. Cellular operations are not subject to rate
regulation.



PROPERTY, PLANT AND EQUIPMENT



    TELEPHONE plant is stated substantially at original cost of construction.
Telephone plant retired in the ordinary course of business, together with cost
of removal, less salvage, is charged to accumulated depreciation with no gain or
loss recognized. Renewal and betterment of telephone plant are capitalized while
repairs, as well as renewals of minor items, are charged to operating expense.
The Company provides for depreciation of telephone plant on the straight-line
method, using rates approved by the regulatory authorities.



    NON-TELEPHONE plant is stated at purchase cost and, when sold or retired, a
gain or loss is recognized. Depreciation of such property is provided on the
straight-line method over its estimated service live ranging from three to
15 years.



CELLULAR LICENSES



    Cellular licenses are stated at net book value. Amortization is computed on
the straight-line method over an estimated useful life of 40 years. These are
renewable at our option in perpetuity.



GOODWILL



    Goodwill associated with the purchase of rural telephone properties is
amortized on the straight-line method over 40 years and 15 years for all other.



REVENUE RECOGNITION



    Recurring revenues are billed one month in advance and are deferred until
the month earned. Nonrecurring revenues area billed in arrears and are
recognized when earned.



IMPAIRMENT OF LONG-LIVED ASSETS



    The Company has adopted FASB Statement No. 121, ACCOUNTING FOR THE
IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF.
Under the provisions of this statement, the Company has evaluated its long-lived
assets for financial impairments and will continue to evaluate them if events or
changes in circumstance indicate the carrying amount of such assets may not be
fully recoverable on an undiscounted cash flow basis.



EARNINGS PER SHARE



    Earnings per share is based on the weighted average number of shares of
common stock outstanding from May 14, 1999 through September 30, 1999 (basic
earnings per share) and dilutive common equivalent shares from stock options and
warrants, using the treasury stock method (dilutive earnings per share). The
weighted average number of shares outstanding is calculated from May 14, 1999
because the Company had no significant operations or outstanding shares prior

to that date. Common stock equivalent shares were antidilutive for the period
ended September 30, 1999.



COMPREHENSIVE INCOME (LOSS)



    The Company has adopted FASB Statement No. 130, COMPREHENSIVE INCOME. The
Company's comprehensive loss is equal to its net loss.



2. ACQUISITIONS



    On May 14, 1999, Alaska Communications Systems Holdings Inc. ("ACS"),
acquired Century's Alaska holdings (PTI properties), including Telephone
Utilities of Alaska, Inc., Telephone Utilities of the Northland, Inc., PTI
Communications of Alaska, Inc., Pacific Telecom of Alaska PCS, Inc., and Pacific
Telecom Cellular of Alaska, Inc., excluding the assets, liabilities and equity
of Alaska RSA#1. On the same date, ACS also acquired from the Municipality of
Anchorage ATU Communications, Inc. and its subsidiaries, MACtel and ATU Long
Distance (collectively, "ATU"). These holdings include local area exchanges,
long distance service, Internet service and cellular operations throughout rural
Alaska and Anchorage. Both acquisitions were accounted for under the purchase
method of accounting. The financial statements reflect the allocation of the
purchase price and assumption of certain liabilities and include the operating
results of both ATU and PTI properties from the date of acquisition. In total,
the Company paid Century Telephone Enterprise $411,784 for the PTI properties
and the Municipality of Anchorage $265,115 for the assets acquired. Deferred
acquisition expenses totaling $14,079 were also allocated to the purchase price.
The purchase price information presented is subject to final settlement
adjustments, which management does not expect to be material.



    The following reflects the preliminary allocation of the purchase price and
the sources of funds to finance the purchase (in thousands).

</TABLE>



    The Company's senior discount debentures balance of $21,186 consists of the
$25,000 issue price plus accrued interest of $1,221 minus unamortized original
issue discount of $5,035. The original issue discount resulted from the issuance
of detachable warrants in connection with the 13% senior discount debentures.
These detachable warrants are exercisable into 828,261 shares of common stock at
any time from May 14, 1999 through May 15, 2011 at $0.01 per share. The original
issue discount represents the difference between the exercise price and the fair
value of the underlying shares at the date of issue.



4. STOCK OPTIONS



    At September 30, 1999, the Company has reserved a total 3,410,486 shares of
authorized common stock for issuance under the 1999 Stock Incentive Plan ("the
Plan"). At September 30, 1999, 3,328,000 options have been granted under the
Plan at an exercise price of $6.1542 per share, generally vesting ratably over
five years or after nine years subject to acceleration upon the attainment of
certain performance goals. During May, June and July of 1999, 2,858,000 of these
options were granted at an exercise price equivalent to the then fair value of
the underlying stock as evidenced by sales to third parties. On September 28,
1999, 470,000 options were granted below the independently appraised fair value
of the underlying stock at the time of issuance, which was $10.12. Additionally,
the terms of the 470,000 options granted below fair value on September 28, 1999
call for immediate vesting upon the successful completion of an initial public
offering ("IPO"), which the Company is currently contemplating.



    Of the options granted in May, 653,750 are performance vesting options
granted to certain officers and management of the Company. The original terms of
these particular performance vesting options call for vesting based upon the
achievement of certain annual performance goals. During October 1999 these
options were amended to allow for the immediate vesting upon successful
completion of an IPO.

                       (UNAUDITED, DOLLARS IN THOUSANDS)



4. STOCK OPTIONS (CONTINUED)



    Included on the balance sheet at September 30, 1999 is unearned compensation
of $1,864 related to the 470,000 options granted on September 28, 1999. This
unearned compensation expense will be amortized as a non-cash expense over the
vesting term of the options or immediately upon the successful completion of an
IPO, whichever occurs first. The 653,750 options granted on May 14, 1999 will be
recorded as compensation expense when vesting occurs. Compensation expense will
be recorded upon the earlier of achieving the annual corporate level performance
goals or the successful completion of an IPO. Compensation expense recorded will
be the difference between the market price of the shares on the day vesting is
determined and the exercise price of $6.1542.



5. BUSINESS SEGMENTS



    The Company has adopted FASB Statement No. 131, DISCLOSURES ABOUT SEGMENTS
OF AN ENTERPRISE AND RELATED INFORMATION. The Company has three reportable
segments: local telephone (consisting of local telephone service, directory
advertising, deregulated revenue and other revenues), cellular and long
distance. Each reportable segment is a strategic business under separate
management and offering different services than those offered by the other
segments.



    The accounting policies of the segments are the same as those described in
the summary of significant accounting policies.



    The Company also incurs interest expense, interest income, equity in
earnings of minority investments and other non operating income and expense at
the corporate level which are not allocated to the business segments, nor are
they evaluated by the chief operating decision maker in analyzing the
performance of the business segments. These non operating income and expense
items are provided in the accompanying table under the caption "Other" in order
to assist the users of these financial statements in reconciling the operating
results and total assets of the business segments to the consolidated financial
statements.

</TABLE>



6. INCOME TAXES



    The tax benefit reported for the consolidated period ended September 30,
1999 is due to investment tax credits that the Company is eligible to take
regardless of its net loss position for the period. In general, the provision
for income taxes may differ from the federal statutory rate due to the effect of
federal and state alternative minimum taxes and net operating losses incurred
for the period that are not benefited. In the current period, operating losses
were not benefited because it is not certain that the Company will be able to
use the losses going forward.

         ALASKA COMMUNICATIONS SYSTEMS HOLDINGS, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

    PERIOD FROM JULY 16, 1998 (DATE OF INCEPTION) THROUGH DECEMBER 31, 1998
           AND FOR THE THREE MONTHS ENDED MARCH 31, 1999 (UNAUDITED)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    The consolidated financial statements for Alaska Communications Systems
Holdings, Inc. and Subsidiaries (the "Company") represent the operating results
of the following three legal entities:

        Alaska Communications Systems Holdings, Inc. (formerly ALEC Acquisition
    Corporation)

        ALEC Acquisition Sub Corp., Inc.

        Alaska Communications Systems, Inc.

    The Company was organized in 1998 as the principal entity to acquire and
manage telecommunication operations in Alaska. The principal activities in 1998
and through March 31, 1999 were the preparation of systems and obtaining
financing for pending acquisitions (see Note 5). In May 1999, the Company was
acquired and became a wholly owned subsidiary of ALEC Holdings, Inc.

    A summary of significant accounting policies followed by the Company is set
forth below:

    USE OF ESTIMATES--The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of commitments and contingencies at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results may differ from those estimates.

    PROPERTY, PLANT, AND EQUIPMENT is stated at cost. At December 31, 1998, the
Company was in the early stages of opening its Corporate Headquarters in
Anchorage. No depreciation was claimed in 1998 since the assets in service were
acquired at year end.

    DEFERRED ACQUISITION AND FINANCING COSTS are stated at cost and are direct
costs incurred in connection with the Company's acquisitions and related
financings.

    REVENUES--No revenues or expenses have been generated since the Company was
not in operation as of December 31, 1998.

2. TRANSACTIONS WITH RELATED PARTIES

    Fox Paine Capital Fund, the majority stockholder of the Company's parent,
ALEC Holdings, Inc., has advanced cash to allow the Company to operate until
permanent funding is put in place at the closing of the acquisitions (see
Note 5). Outstanding advances were $620,000 as of December 31, 1998. Fox Paine
Capital Fund will continue to fund the Company until permanent funding is
obtained at the closing of the acquisitions.

    The Company advanced cash to a related party to perform certain consulting
services in connection with the Company's pending acquisitions. Cash used is
capitalized as deferred acquisition costs. Any unused cash that was advanced to

5. COMMITMENTS AND CONTINGENCIES

    The Company has announced two purchase agreements that will allow the
Company to enter the telecommunications industry. The first agreement involves
the acquisition of CenturyTel's Alaska holdings including Telephone Utilities of
Alaska, Inc., Telephone Utilities of the Northland, Inc., PTI Communications of
Alaska, Inc., Pacific Telecom of Alaska PCS, Inc., and Pacific Telecom Cellular
of Alaska, Inc. and the second is with the Municipality of Anchorage to acquire
all of its telecommunication investments. Upon completion of these two
contracts, the Company will have in excess of 300,000 local telephone, 70,000
cellular, 20,000 long distance, and 16,000 Internet access lines. The combined
purchase price is approximately $700 million. The Company is being funded by a
$145 million equity contribution from its parent, ALEC Holdings, Inc., and the
remainder with bank financed debt.

    It is currently anticipated that by mid-1999 all regulatory approvals will
have been granted and the acquisitions will be completed. At that time, the
Company's primary business will be to provide traditional local telephone, long
distance, cellular, and Internet service throughout the state of Alaska. Until
the completion of the acquisitions, the Company is incurring costs to facilitate
certain transition and financing activities.

                                 (IN THOUSANDS)

1. GENERAL AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    GENERAL--The combined financial statements for CenturyTel Alaska Properties
(the "Company") represent the operating results of the following legal entities
("Alaskan Entities"):

    Telephone Utilities of Alaska, Inc. ("TUA")

    Telephone Utilities of the Northland, Inc. ("TUN")

    PTI Communications of Alaska, Inc. ("PTICA")

    Pacific Telecom of Alaska PCS, Inc. ("PTAPCS")

    Pacific Telecom Cellular of Alaska, Inc. ("PTCA"), excluding the assets,
liabilities and equity of Alaska RSA #1

    TUA, TUN, PTICA, and PTAPCS were wholly owned subsidiaries of Pacific
Telecom, Inc. ("PTI") and PTCA was a wholly owned subsidiary of Pacific Telecom
Cellular, Inc., which was a wholly owned subsidiary of PTI. Until December 1,
1997, PacifiCorp Holdings owned 100% of the voting securities of PTI. The
Company was acquired on December 1, 1997 as a result of Century Telephone
Enterprises, Inc.'s ("CenturyTel") acquisition of Pacific Telecom, Inc. (the
"Acquisition") (Note 13). The financial statements beginning December 1, 1997
reflect the excess cost of net assets acquired and the subsequent amortization
expense which was allocated to the Alaska properties in accordance with purchase
accounting.

    TUA, TUN, PTICA, and PTAPCS became wholly owned subsidiaries of CenturyTel
of the Northwest, Inc. ("CNI") which is a wholly owned subsidiary of CenturyTel.
PTCA is a wholly owned subsidiary of CenturyTel Wireless, Inc. ("CT Wireless")
which is a wholly owned subsidiary of CenturyTel.

    The Company's primary business is to provide traditional and cellular
telephone service to its customers which are located in the state of Alaska. The
Company was dependent on PTI and certain subsidiaries prior to the Acquisition
and is dependent upon CenturyTel and certain CenturyTel subsidiaries to provide
construction and maintenance services, materials and supplies and managerial,
technical and accounting services. Intercompany billings include a return on
investment to the related company.

    The Company's telephone operations are regulated in nature and its telephone
accounting records are maintained in accordance with the rules and regulations
of the Alaska Public Utilities Commission ("APUC") which substantially adhere to
the rules and regulations of the Federal Communications Commission. The
Company's regulated operations are subject to the provisions of Statement of
Financial Accounting Standards ("SFAS") No. 71, ACCOUNTING FOR THE EFFECTS OF
CERTAIN TYPES OF REGULATION.

    ESTIMATES--The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the

reported amounts of assets and liabilities and disclosure of contingent assets
and liabilities at the date of the financial statements and the reported amounts
of revenues and expenses during the reporting period. Actual results may differ
from those estimates.

    REVENUE RECOGNITION--Revenues are recognized when earned. The Company
participates in toll revenue pools with other telephone companies. Such pools
are funded by toll revenue and/or access charges regulated by the APUC within
the intrastate jurisdiction and the Federal Communications Commission within the
interstate jurisdiction. Much of the interstate toll service revenue earned
through various pooling processes is initially recorded based on estimates.
These estimates are derived from interim financial statements, available
separations studies and the most recent rate of return published by the National
Exchange Carriers Association. These estimates are subject to subsequent
adjustment in future accounting periods as refined operational information
becomes available. Any subsequent adjustments have not been material.

    PROPERTY, PLANT, AND EQUIPMENT--Telephone plant is stated substantially at
original cost of construction. Telephone plant retired in the ordinary course of
business, together with cost of removal, less salvage, is charged to accumulated
depreciation with no gain or loss recognized. Renewals and betterments of
telephone plant are capitalized while repairs, as well as renewals of minor
items, are charged to operating expense.

    The Company provides depreciation for telephone plant on the straight-line
method, using rates approved by the regulatory authorities. Depreciation expense
for telephone plant amounted to $13,774, $14,406, $1,737, and $23,550 for the
year ended December 31, 1996, eleven months ended November 30, 1997, one month
ended December 31, 1997, and year ended December 31, 1998, respectively.
Included in 1998 expense is additional depreciation of approximately $1,506
which was approved by the regulatory authorities. The composite depreciation
rate was 5.7% for the year ended December 31, 1996, 5.8% for the eleven months
ended November 30, 1997 and the one month ended December 31, 1997, and 6.1% for
the year ended December 31, 1998.

    Non-telephone plant is stated at cost and, when sold or retired, a gain or
loss is recognized. Depreciation of such property is provided on the
straight-line method over its estimated service lives ranging from 7 to
15 years. Depreciation for non-telephone plant amounted to $1,198, $922, $190,
and $583 for the year ended December 31, 1996, eleven months ended November 30,
1997, one month ended December 31, 1997, and the year ended December 31, 1998,
respectively.

    LONG-LIVED ASSETS AND EXCESS COST OF NET ASSETS ACQUIRED (GOODWILL)--The
carrying value of long-lived assets, including allocated goodwill, is reviewed
for impairment at least annually, or whenever events or changes in circumstances
indicate that such carrying value may not be recoverable, by assessing the
recoverability of such carrying value through estimated undiscounted future net
cash flows expected to be generated by the assets. The excess cost of net assets
acquired is being amortized over 40 years. Amortization expense was $333 for the
year ended

during the one month ended December 31, 1997, and $6,326 for the year ended
December 31, 1998.

    INCOME TAXES--Prior to the Acquisition, the Company was included in the
consolidated federal income tax return of PacifiCorp Holdings and CenturyTel in
subsequent periods. For financial accounting purposes, federal income taxes are
computed and recorded as if the Company filed a separate federal income tax
return, except that, (i) in the event the Company generates a net tax loss which
is utilized in the respective consolidated return, the Company will be given the
benefit of such loss, and (ii) income taxes are calculated based upon the
statutory tax rate in effect for PacifiCorp prior to the Acquisition and
CenturyTel and its subsidiaries for subsequent periods on a consolidated basis.
The Company periodically settles amounts owed to CenturyTel for federal income
taxes. The Company is included in a consolidated Alaska state income tax return.

    The Company uses the asset and liability method of accounting for income
taxes under which deferred tax assets and liabilities are established for the
future tax consequences attributable to differences between the financial
statement carrying amounts of assets and liabilities and their respective tax
bases. Investment tax credits related to plant have been deferred and are being
amortized as a reduction of federal income tax expense over the estimated useful
lives of the assets giving rise to the credits.

    Pursuant to SFAS 71, the regulatory liability, net of the related tax
impact, is being amortized as a reduction of federal income tax expense over the
estimated remaining lives of the assets which generated the deferred taxes.

    CASH EQUIVALENTS--For purposes of the statement of cash flows, the Company
considers all demand deposits, central depository bank account ("CDA") deposits,
and all short-term investments with a maturity at date of purchase of three
months or less to be cash equivalents.

    INVESTMENTS--The Rural Telephone Bank ("RTB") requires borrowers of RTB
funds to purchase RTB stock as a percentage of loan funds provided. These
investments have been accounted for using the cost method.

    ADVANCE BILLINGS--Advance billings creditable to revenue accounts in future
months are recorded in advance billings until the service is rendered.

    EARNINGS PER SHARE--The common stock of the Company is not traded in a
public market; therefore, earnings per share amounts are not presented in
accordance with SFAS 128, EARNINGS PER SHARE.

2. PCS LICENSE ACQUISITION COSTS

    In early 1997, the Company was awarded three 10 MHz licenses to provide
personal communications services ("PCS") in Alaska. The Company paid $3,023 for
such licenses, which will

    CASH AND CASH EQUIVALENTS, ACCOUNTS RECEIVABLE, ACCOUNTS PAYABLE, ACCRUED
EXPENSES, AND CUSTOMER DEPOSITS--The carrying amount approximates the fair value
due to the short maturity of these instruments.

    OTHER INVESTMENTS--The Company's other investments are represented by its
investment in RTB stock. The carrying amount of such investment approximates the
fair market value of these instruments.

    LONG-TERM DEBT--The carrying value of the Company's long-term debt had a
fair value of $42,669 at December 31, 1997 and $45,853 at December 31, 1998. The
fair value was estimated by discounting the scheduled payment streams to present
value based upon rates currently offered to the Company for debt of similar
remaining maturities. Prepayment penalties and other costs of debt retirement
are not reflected in the estimates.

7. EMPLOYEE BENEFIT PLANS

    Substantially all employees of the Company, except those which are members
of the International Brotherhood of Electrical Workers ("IBEW"), are covered by
a pension plan (the "Plan") which is sponsored by PTI before the Acquisition and
CNI subsequently which includes other affiliated companies. The Plan provides
benefits based upon employees' total years of service and the highest five years
compensation during their last 10 years of service. The Company's portion of
pension income was $57 during the year ended December 31, 1996, $219 during the
eleven months ended November 30, 1997, $23 during the one month ended
December 31, 1997, and $384 for the year ended December 31, 1998. Because
actuarial information regarding the status of the Plan is computed for the Plan
in total, the Company does not separately determine its portion of the actuarial
present value of the accumulated plan benefits, projected benefit obligation, or
net assets available for benefits.

    In accordance with the purchase agreement with Alaska Communications Systems
Holdings, Inc., formerly known as ALEC Acquisition Corporation ("ALEC") (see
Note 13), the Plan assets and obligations will be valued at the closing date.
Based on this valuation, assets equaling the actuarial present value of the
accrued benefits of the Company's employees, plus an additional $250, will be
transferred to a replacement plan.

7. EMPLOYEE BENEFIT PLANS (CONTINUED)

    The Company participates in a postretirement health care and insurance plan
(the "PRB Plan") which is sponsored by PTI prior to acquisition and by CNI
subsequently which includes other affiliated companies.

    The Company recognizes the cost of other postretirement benefits over the
active service period of its employees. PTI's policy was to fund annually an
amount of the postretirement benefit liability that will systematically reduce
that liability using available funds and allow deductibility for federal income
tax purposes. Due to income tax regulations that restrict the deductibility of
certain contributions for postretirement benefits, PTI elected to make non-tax
contributions to meet funding requirements imposed by state regulatory
commissions. PTI recognized the transition obligation, which represents the
previously unrecognized prior service cost, over a period of 20 years. Because
actuarial information regarding the status of the PRB Plan is computed for the
PRB Plan in total, PTI did not separately determine its portion of the actuarial
present value of the accumulated plan benefit, projected benefit obligations or
net assets available for benefits. At December 31, 1997, the date of the latest
actuarial evaluation for the PRB Plan, plan assets were less than the projected
benefit obligation by approximately $46,246 and the unamortized portion of the
transition obligation was $26,099. The Company's portion of the net periodic
postretirement benefit cost was $846 during the year ended December 31, 1996,
$485 during the eleven months ended November 30, 1997, $41 during the one month
ended December 31, 1997, and $471 during the year ended December 31, 1998, as

    At the time of adoption of SFAS 106, EMPLOYERS' ACCOUNTING FOR
POSTRETIREMENT BENEFITS OTHER THAN PENSIONS, the Company elected to amortize the
transition obligation, at the date of implementation, over 20 years.

    In accordance with the purchase agreement with ALEC (see Note 13), the
purchaser assumes the liability for postretirement benefits related to employees
that retire subsequent to the closing date.

8. CERTAIN TRANSACTIONS

    The Company purchases certain plant materials and other services (including
certain operating expenses) from PTI, CenturyTel, and other affiliated
companies. Materials and services purchased by the Company from PTI prior to
acquisition and CenturyTel and its subsidiaries subsequently totaled
approximately $9,227 for the year ended December 31, 1996, $8,581 for the eleven
months ended November 30, 1997, $1,626 for the one month ended December 31,
1997, and $29,306 (which included $15,648 of operating expenses) during the year
ended December 31, 1998. Many of the costs that are allocated to the Alaska
companies are based on time distribution and are, therefore, representative of
what costs would have been on a stand-alone basis. General and administrative
costs are allocated based on expense levels of all companies. Such costs, when
allocated to the subsidiaries, include a reasonable rate of return on investment
to the related affiliate and, therefore, are representative of what costs would
have been on a stand-alone basis.

    Prior to the Acquisition, short-term advances were made to PTI under an
agreement providing interest at the prime commercial rate for funds held more
than 90 days. Interest income on these advances was $1,052 during the year ended
December 31, 1996, $797 during the eleven months ended November 30, 1997, and
$81 during the one month ended December 31, 1997.

    Subsequent to the Acquisition, the Company participates in a Central
Depository Account ("CDA") with CenturyTel and other affiliates. The Company is
assessed or receives interest on the net amount of its CDA balance and the net
accounts receivable or payable to CenturyTel and its affiliates. Related
interest income amounted to $2,156 for the year ended December 31, 1998. The
rate used to calculate the related interest income was the three month U.S.
T-Bill rate. Related interest expense amounted to $637 for the year ended
December 31, 1998. The rate used to calculate the related interest expense was
the weighted average rate of CenturyTel's debt.

9. BUSINESS AND CREDIT CONCENTRATIONS

    The Company provides telephone services to customers (business and
residential) located in the state of Alaska. Receivables from connecting
companies represent the amounts due from various long distance carriers such as
AT&T and the Bell operating companies.

    The ultimate realization of the Company's balance in the CDA discussed above
is dependent upon the financial resources of CenturyTel.

10. COMMITMENTS AND CONTINGENCIES

    Expenditures for property, plant, and equipment are anticipated to be
approximately $19,469 for telephone operations and $615 for wireless operations
during 1999.

    The Company is involved in various claims and legal actions arising in the
ordinary course of business. In the opinion of management, the ultimate
disposition of the matters will not have a material adverse effect on the
Company's financial position or results of operations.

10. COMMITMENTS AND CONTINGENCIES (CONTINUED)

    The Company's operations are subject to federal, state and local laws and
regulations governing the use, storage, disposal of, and exposure to, hazardous
materials, the release of pollutants into the environment and the remediation of
contamination. As an owner or operator of property and a generator of hazardous
wastes, the Company could be subject to certain environmental laws that impose
liability for the entire cost of cleanup at contaminated sites, regardless of
fault or the lawfulness of the activity that resulted in contamination. The
Company believes, however, that its operations are in substantial compliance
with applicable environmental laws and regulations and that there is no material
exposure to loss related to environmental issues.

    Many of the Company's properties formerly contained, or currently contain,
underground and aboveground storage tanks used for the storage of fuel or
wastes. Some of these tanks have leaked. The Company believes that known
contamination caused by these leaks has been, or is being, investigated or
remediated. The Company cannot be sure, however, that it has discovered all
contamination or that the regulatory authorities will not request additional
remediation at sites that have previously undergone remediation.

12. ACCOUNTING FOR THE EFFECTS OF REGULATION

    The Company currently accounts for its regulated telephone operations in
accordance with the provisions of SFAS 71. While the ongoing applicability of
SFAS 71 to the Company's telephone operations is being monitored due to the
changing regulatory, competitive, and legislative

12. ACCOUNTING FOR THE EFFECTS OF REGULATION (CONTINUED)

environments, the Company believes that SFAS 71 still applies. However, it is
possible that changes in regulation or legislation or anticipated changes in
competition or in the demand for regulated services or products could result in
the Company's telephone operations not being subject to SFAS 71 in the near
future. In that event, implementation of SFAS 101, REGULATED
ENTERPRISES--ACCOUNTING FOR THE DISCONTINUANCE OF APPLICATION OF FASB STATEMENT
NO. 71, would require the write-off of previously established regulatory assets
and liabilities, along with an adjustment of certain accumulated depreciation
accounts to reflect the difference between recorded depreciation and the amount
of depreciation that would have been recorded had the Company's telephone
operations not been subject to rate regulation. Regulatory assets were
$45,600,000, and regulatory liabilities were $880,000. Such discontinuance of
the application of SFAS 71 would result in a material, noncash charge against
earnings which would be reported as an extraordinary item. While the effect of
implementing SFAS 101 cannot be precisely estimated at this time, management
believes that the noncash, after-tax, extraordinary charge would be between
$25,000 and $28,000.

13. ACQUISITIONS AND DISPOSITIONS

    On September 8, 1997, the Company acquired the outstanding stock of
Polarnet, Inc., an Internet service provider. The purchase price was
approximately $1,100 and was accounted for by the purchase method. The excess of
the purchase price over the estimated fair value of net assets acquired amounted
to approximately $968, which is included in goodwill. The results of operations
of Polarnet, Inc. from September 8, 1997 are included in the statement of
income.

    On October 6, 1997, PTI acquired the net assets of the local exchange
utilities ("PTI-Fairbanks") from the City of Fairbanks. The purchase price was
approximately $87 million and was accounted for by the purchase method. The
excess of the purchase price over the estimated fair value of net assets
acquired amounted to approximately $31 million, which is included in goodwill.
The results of operations of PTI-Fairbanks from October 6, 1997 are included in
the statements of income. Assets and liabilities acquired were as follows:

    On December 1, 1997, PTI was sold to CenturyTel for approximately
$2.2 billion (including assumed debt). As a result of this transaction, the
Company recorded all previously retained earnings as paid-in capital and pushed
down excess costs of approximately $208 million to the Alaskan entities to
reflect the change from PTI's to CenturyTel's basis of accounting.

    In August 1998 CNI and CT Wireless entered into a definitive agreement to
sell the stock of the Company to ALEC for approximately $409 million, subject to
certain adjustments. The transaction is anticipated to close in 1999 subject to
regulatory approvals and various closing conditions.

14. YEAR 2000 (UNAUDITED)

    The Company has initiated a plan ("Year 2000 Plan") to identify, assess, and
remediate "Year 2000" issues within each of its significant computer programs
and certain equipment which contain micro-processors. The Year 2000 Plan is
addressing the issue of computer programs and embedded computer chips being
unable to distinguish between the year 1900 and the year 2000, if a program or
chip uses only two digits rather than four to define the applicable year. The
Company has divided the Year 2000 Plan into four major phases--assessment,
planning, implementation, and testing. After completing the assessment and
planning phases earlier this year, the Company is currently in the
implementation and testing phases. Systems which have been determined not to be
Year 2000 compliant are being either replaced or reprogrammed, and thereafter
tested for Year 2000 compliance. The Year 2000 Plan anticipates that by
October 1999 the implementation and testing phases will be completed.

    The Company is identifying and contacting critical suppliers and customers
whose computerized systems interface with the Company's systems, regarding their
plans and progress in addressing their Year 2000 issues. The Company has
received varying information from such third parties on the state of compliance
or expected compliance. Contingency plans are being developed in the event that
any critical supplier or customer is not compliant.

    The failure to correct a material Year 2000 problem could result in an
interruption in, or a failure of, certain normal business activities or
operations. Such failures could materially and adversely affect the Company's
operations, liquidity, and financial condition. Due to the general uncertainty
inherent in the Year 2000 problem, resulting in part from the uncertainty of the
Year 2000 readiness of third-party suppliers and customers, the Company is
unable to determine at this time whether consequences of Year 2000 failures will
have a material impact on the Company's operations, liquidity, or financial
condition.

Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
In the opinion of management, all adjustments (consisting only of normal
recurring accruals) considered necessary for a fair presentation have been
included. Operating results for the three month period ended March 31, 1999 are
not necessarily indicative of the results that may be expected for the full
fiscal year or for any future period.

                          INDEPENDENT AUDITORS' REPORT

Board of Directors
Century Telephone Enterprises, Inc.
Monroe, Louisiana

    We have audited the combined balance sheet of Telephone Fund of Fairbanks
Municipal Utilities Services (the "Company") as of October 6, 1997, and the
related combined statements of income and fund equity and of cash flows for the
period ended October 6, 1997 and the year ended December 31, 1996. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the combined financial position of Telephone Fund of
Fairbanks Municipal Utilities Services as of October 6, 1997, and the results of
their operations and their cash flows for the period ended October 6, 1997 and
the year ended December 31, 1996 in conformity with generally accepted
accounting principles.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    The Telephone Utility of Fairbanks Municipal Utilities Services' (the
"Company") primary business is to provide telephone service to its customers who
are located in the City of Fairbanks and surrounding local areas. The Company's
telephone operations are regulated in nature and its telephone accounting
records are maintained in accordance with the rules and regulations of the
Alaska Public Utilities Commission ("APUC") which substantially adhere to the
rules and regulations of the Federal Communications Commission. The Company's
regulated operations are subject to the provisions of Statement of Financial
Accounting Standards No. 71 ("SFAS 71"), ACCOUNTING FOR THE EFFECTS OF CERTAIN
TYPES OF REGULATION. In an asset purchase agreement effective October 6, 1997,
the Company was sold by the Municipal Utilities System ("MUS"), an enterprise
fund of the City of Fairbanks, to PTI Communications of Alaska, Inc. and began
doing business as PTI-Fairbanks. The financial statements do not reflect any
purchase adjustments from this transaction. The financial statements also
exclude the cellular fund which operates the RSA #1 A-Side cellular property
site license.

    The accompanying financial statements represent the financial position of
the Company as of October 6, 1997 and the results of its operations and cash
flows for the period ended October 6, 1997 and the year ended December 31, 1996.

    A summary of significant accounting policies followed by the Company is set
forth below:

    USE OF ESTIMATES--The preparation of financial statements in conformity with
generally accepted accounting principles requires Management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of commitments and contingencies at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

    PROPERTY, PLANT, AND EQUIPMENT--The Company states its property, plant and
equipment at cost. Additions to plant include direct costs and related indirect
charges. Depreciation is provided using the straight-line method based primarily
on the estimated service lives of the various classes of depreciable assets. The
composite depreciation rate for depreciable telecommunications plant was 5.7%
for the period ended October 6, 1997 and 4.9% for the year ended 1996.

    INCOME TAXES--As MUS is a public entity, it is exempt from paying any
federal, state or local taxes. In place of property taxes, MUS makes a payment
in lieu of taxes (see Note 2).

    REVENUE RECOGNITION--The Company participates in access revenue pools for
certain interstate and intrastate revenues, which are initially recorded based
on estimates. Certain network access revenues are estimated under cost
separations procedures that base revenues on current operating costs and
investments in facilities to provide such services. These estimates are derived
from interim financial statements, available separations studies and the most
recent rate of return published by the National Exchange Carriers Association.
These estimates are subject to subsequent adjustment in future accounting
periods as refined operational information becomes available. Any subsequent
adjustments have not been material.

    ADVANCE BILLINGS--Advance billings creditable to revenue accounts in future
months are recorded in advance billings until the service is rendered.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    DEFERRED CREDIT--In prior years contributions were made by outside third
parties to fund construction of certain property, plant, and equipment of the
Company. These contributions have been recorded as a deferred credit and are
being amortized over the lives of the funded assets.

2. TRANSACTIONS WITH RELATED PARTIES

    The Company purchases certain administrative, engineering, personnel, and
legal services from the City of Fairbanks. These services, which are charged at
cost to various capital and expense accounts, were $596 for the period ended
October 6, 1997 and $853 for the year ended December 31, 1996.

    The Company makes payments in lieu of taxes at 4% of gross revenue, with
payments capped at $2,243, plus a 3% supplemental, with payments capped at
$1,300 for all utilities. Payments in lieu of taxes to the City of Fairbanks
General Fund by the Company amounted to $1,536 for the period ended October 6,
1997 and $1,715 for the year ended December 31, 1996.

    MUS also allocates interest expense on revenue bonds as well as interest
income earned on short-term investments to each of its utilities as part of its
centralized cash management program. The amount of interest expense and income
allocated to the Company was $1,520 and $416 during the period ended October 6,
1997 and $1,552 and $462 during the year ended December 31, 1996.

4. EMPLOYEE BENEFIT PLANS

    All permanent employees of the Company are eligible to participate as
members of the State of Alaska Public Employees Retirement System ("PERS"), a
defined benefit agent multiple-employer public employee retirement system that
acts as a common investment and administrative agent for the State of Alaska and
any political subdivision or public organization that elects to join the system.
Eligible employees contribute 6.75% of their gross salary to PERS. The Company
is required to contribute the remaining amounts necessary to fund PERS, using
the actuarial basis specified by the PERS Board. Because actuarial information

is computed for the Plan in total, the Company does not separately determine its
portion of the actuarial present value for the accumulated plan benefits,
projected benefit obligation, or net assets available for benefits. At June 30,
1997, the date of the latest actuarial evaluation for the Plan, Plan assets of
$70,726 exceeded the projected benefit obligation by approximately $33,837.

    Certain employees of the Company are members of the International
Brotherhood of Electrical Workers ("IBEW") and are eligible to participate in
two different union-sponsored multiple employer defined benefit plans, a pension
plan and a thrift plan. Under the pension plan, the Company contributed between
$4 and $5.09 per compensable hour to the Alaska Electrical Pension Fund and the
total contribution was $782 for the period ended October 6, 1997 and $864 for
the year ended December 31, 1996. Under the thrift plan, the Company pays a
minimum of 4% of the participant's gross wages into the plan plus after one year
it matches the employee's contributions, to a maximum of 3%. The Company's
contributions to the thrift plan was $332 for the period ended October 6, 1997
and $298 for the year ended December 31, 1996.

5. EMPLOYEES' DEFERRED COMPENSATION

    The Company offers its employees three deferred compensation plans which are
part of the MUS multiemployer plan. The plans are available to all Company
employees and permit them to defer a portion of their salary until future years.
Participants' rights under the plans are equal to those of general creditors of
MUS in an amount equal to the fair market value of the deferred account for each
participant. The fair market value of both the assets and liabilities for the
Plan in total at October 6, 1997 was $13,247.

6. COMMITMENTS AND CONTINGENCIES

    Expenditures under the Company's 1998 construction and capital expenditure
program are expected to approximate $7,193.

December 31, 1998. These financial statements are the responsibility of the
Utility's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    The financial statements present only the Municipality of Anchorage
Telephone Utility Fund and are not intended to present fairly the financial
position and results of operations of the Municipality of Anchorage in
conformity with generally accepted accounting principles.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of the Municipality of
Anchorage Telephone Utility Fund as of December 31, 1998 and 1997, and the
results of its operations and its cash flows for each of the years in the
three-year period ended December 31, 1998 in conformity with generally accepted
accounting principles.

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    DESCRIPTION OF BUSINESS

    The accompanying financial statements include the activities of the
Telephone Utility Fund (Utility), a public utility of the Municipality of
Anchorage (Municipality), ATU Communications, Inc. (ACI), a holding company,
MACtel, Inc. (MACtel) and ATU Long Distance, Inc. (ATU LD), wholly owned
subsidiaries of ACI. All significant intercompany transactions have been
eliminated.

    The regulated arm of the Utility provides local telecommunications service
and access to long distance telecommunications service to the Anchorage Bowl
area and to Girdwood and other small communities in the area south of the
Anchorage Bowl both inside and outside the boundaries of the Municipality. The
nonregulated arm of the Utility sells, rents, and leases customer premise
equipment to customers throughout the State of Alaska. MACtel is a
wholesale/retail cellular service provider that operates in Anchorage, the Kenai
Peninsula, and the North Star and North Slope Boroughs. ATU LD provides long
distance service to customers in Anchorage, Fairbanks, Juneau, the Kenai
Peninsula and the Matanuska Valley. Approximately 70% of the Utility's employees
are covered under a labor contract with the International Brotherhood of
Electrical Workers (IBEW) which expires on August 31, 1999.

    On January 5, 1998, MACtel acquired certain assets of Pacific Telecom
Cellular of Alaska RSA #1, Inc. and stock of Prudhoe Communications, Inc.,
collectively d/b/a Cellulink, a cellular service company in Fairbanks, Alaska
for $8,900.

    The purchase price was allocated as follows:

    Results of operations for the acquired companies have been included in 1998
operations since the date of acquisition. Pro forma information for prior
periods is not presented because it is not material.

    SALE OF UTILITY

    During 1998, the Municipal Assembly accepted a bid in the amount of $295,000
from Alaska Communications Systems, Inc. to acquire substantially all of the
assets and assume substantially all of the liabilities of the Utility. The sale
will become effective after review and approval by the Alaska Public Utilities
Commission (APUC), the Federal Communications Commission (FCC), and non-action
by the United States Department of Justice under the Hart-Scott-Rodino Act. The
sales price will be adjusted based upon levels of cash and net plant on the
closing date.

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    REGULATION

    The Utility is subject to rate regulation by the FCC for interstate
telecommunication service, and the APUC for intrastate and local exchange
telecommunication service. The Utility, as required by the FCC, accounts for
such activity separately.

    The services of ATU LD are subject to rate regulation as a non-dominant
interexchange carrier by the FCC for interstate telecommunication services and
the APUC for intrastate telecommunication services. The operations of MACtel are
not subject to rate regulation.

    BASIS OF ACCOUNTING

    The accounting records of the Utility conform to Part 32 Uniform System of
Accounts as prescribed by the FCC and the APUC.

    The accompanying financial statements are prepared on the accrual basis of
accounting. The accounting policies of the Utility are in conformity with the
requirements of the FCC and the APUC. The Utility prepares its financial
statements in accordance with Statement of Financial Accounting Standards (SFAS)
No. 71, "Accounting for the Effects of Certain Types of Regulation". Accounting
under SFAS No. 71 is appropriate as long as rates are established by or subject
to approval by independent third-party regulators; rates are designed to recover
the specific enterprise's cost-of-service; and in view of demand for service, it
is reasonable to assume that rates are set at levels that will recover costs and
can be collected from customers.

    Under Governmental Accounting Standards Board (GASB) Statement No. 20,
ACCOUNTING AND FINANCIAL REPORTING FOR PROPRIETARY FUNDS AND OTHER GOVERNMENTAL
ENTITIES THAT USE PROPRIETARY FUND ACCOUNTING, the Utility applies all
applicable GASB pronouncements and all Financial Accounting Standards Board
(FASB) Statements and Interpretations, Accounting Principles, Board Opinions and
Accounting Research Bulletins, unless they conflict with or contradict GASB
pronouncements. ATU follows the provisions of GASB Statement No. 27 to account
for pension and post-retirement costs, which differs from FAS Statement No. 87
and FAS Statement No. 106 regarding the methodology for calculation of such
costs and how they are recorded and disclosed. Specifically, GASB Statement No.
27 requires that annual pension cost be equal to the annual required
contributions of the employer (ARC) to the plan for that year calculated via an
actuarial valuation performed in accordance with specific parameters. These
parameters address such matters as the frequency of actuarial valuations,
acceptable actuarial cost methods, asset valuation methodology, minimum and
maximum amortization periods and the amortization method. Generally, employers
are required to record a net pension obligation (NPO) if the ARC calculated in
accordance with the parameters exceeds actual contributions made. Annual pension
cost is calculated as the ARC, one year's interest on the NPO, and certain
required adjustments. Under GASB Statement No. 27, employers are permitted to
apply the measurement and recognition requirements of GASB Statement No. 27 to
postemployment healthcare benefits.

                                 (IN THOUSANDS)

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    Pursuant to GASB Statement No. 27, the Municipality of Anchorage Telephone
Utility Fund recorded annual pension cost of $1,041,000 for the year ended
December 31, 1998, of which $749,520 related to pension benefits and $291,480
related to postemployment healthcare benefits. As of December 31, 1998 and 1997,
there is no NPO.

    Under FASB Statement No. 87, EMPLOYERS' ACCOUNTING FOR PENSIONS, the
following components are included in the net pension cost recognized for a
period by an employer sponsoring a defined benefit pension plan:

    - Service cost

    - Interest cost

    - Actual return on plan assets, if any

    - Amortization of unrecognized prior service cost, if any

    - Gain or loss (including the effects of changes in assumptions) to the
      extent recognized

    - Amortization of the unrecognized net obligation (and loss or cost) or
      unrecognized net asset (and gain) existing at the date of initial
      application of FASB Statement No. 87.

    The service component of net periodic pension cost, the projected benefit
obligation, and the accumulated benefit obligation are based on an attribution
of pension benefits to periods of employee service and on the use of actuarial
assumptions to calculate the actuarial present value of those benefits.
Actuarial assumptions reflect the time value of money (discount rate) and the
probability of payments (assumptions as to mortality, turnover, early
retirement, and so forth).

    Under FASB Statement No. 87, a liability (unfunded accrued pension cost) is
recognized if net periodic pension cost recognized pursuant to FASB Statement
No. 87 exceeds amounts the employer has contributed to the plan. An asset
(prepaid pension cost) is recognized if net periodic pension cost is less than
amounts the employer has contributed to the plan.

    If the accumulated benefit obligations exceeds the fair value of plan
assets, the employer shall recognize in the statement of financial position a
liability (including unfunded accrued pension cost) that is at least equal to
the unfunded accumulated benefit obligation. Recognition of an additional
minimum liability is required in certain other circumstances.

    Accounting for postretirement benefits pursuant to FASB Statement No. 106,
EMPLOYERS' ACCOUNTING FOR POSTRETIREMENT BENEFITS OTHER THAN PENSIONS, is
similar to the accounting proscribed for pension benefits in accordance with
FASB Statement No. 87.

    It is not practicable to quantify the differences between the statements
without an additional complete actuarial valuation because the actuarial
calculations for FAS Statement No. 87 purposes require different assumptions and
represent different measurement bases. Other differences between GASB and FAS
have been evaluated and have been determined not to be material for the periods
presented.

                                 (IN THOUSANDS)

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    In preparing the financial statements, management is required to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities as of the date
of the balance sheet and revenues and expenses for the period. Actual results
could differ from those estimates. The more significant accounting and reporting
policies and estimates applied in the preparation of the accompanying financial
statements are discussed below.

    CASH POOLS AND RESTRICTED INVESTMENTS

    The Municipality uses a central treasury to account for all cash and
investments to maximize interest income. Interest income from cash pool
investments is allocated to the Utility based on its monthly closing cash pool
equity balance. Restricted investments are recorded at fair value. All amounts
in the cash pools and in restricted investments are interest bearing and consist
primarily of repurchase agreements, banker's acceptances or U.S. Government
securities. The Utility adopted GASB Statement No. 31, ACCOUNTING AND FINANCIAL
REPORTING FOR CERTAIN INVESTMENTS AND FOR EXTERNAL INVESTMENT POOLS, during
1998. The impact of adopting this statement was not material to the financial
statements.

    Under GASB Statement No. 3, DEPOSITS WITH FINANCIAL INSTITUTIONS,
INVESTMENTS (INCLUDING REPURCHASE AGREEMENTS), AND REVERSE REPURCHASE
AGREEMENTS, the Utility's cash and investments are classified in credit risk
category 1 because they are insured or registered or are securities held by the
Utility or its agent in the Utility's name.

    STATEMENT OF CASH FLOWS

    The Utility has adopted GASB Statement No. 9, REPORTING CASH FLOWS OF
PROPRIETARY AND NONEXPENDABLE TRUST FUNDS AND GOVERNMENTAL ENTITIES THAT USE
PROPRIETARY FUND ACCOUNTING. For purposes of the statement of cash flows, the
Utility has defined cash as the demand deposits and investments maintained in
the general and construction cash pools, including restricted and unrestricted
balances, as well as cash balances maintained separately from the cash pools.
Maturity periods of investments have been disregarded, since the Utility uses
the general and construction cash pools as demand deposit accounts.

    INVENTORIES

    The Utility's inventories, consisting primarily of parts and supplies, are
valued at the lower of weighted average cost or market.

    TELEPHONE PLANT

    Telephone plant is stated at cost. The additions to telephone plant in
service are recorded at the original cost of contracted services, direct
materials and labor, and indirect overhead charges. When property is retired,
the cost of the property unit, plus removal costs, less salvage, is charged to
accumulated depreciation. Gain or loss on the retirement of regulated telephone
plant is not recognized except for extraordinary retirements.

    The Utility's depreciation is computed using the straight-line method over
the estimated lives of the assets. Current rates on regulated plant were
implemented January 1, 1997 and were based on APUC Docket U-96-78. MACtel and
ATU LD property and equipment are depreciated using the straight-line and
declining balance methods over the estimated useful asset lives.

    The estimated life in years of major plant and equipment categories follows:

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    MINORITY INVESTMENTS

    Minority investments consist of investments in companies which are accounted
for using the equity method.

    CELLULAR LICENSES

    Cellular licenses are stated at net book value. Amortization is computed on
the straight-line method over an estimated useful life of 40 years.

    DISCOUNT ON REVENUE BONDS PAYABLE

    The discount on revenue bonds payable is amortized over the life of the
related bond issue using the effective interest method.

    REVENUE RECOGNITION

    Recurring revenues are billed one month in advance and are deferred until
the month earned. Nonrecurring revenues are billed in arrears and are recognized
when earned.

    During 1998 the Utility participated in both interstate and intrastate
common line pooled settlements. During 1998 the Utility did not participate in
any traffic-sensitive pools. Pooled revenues are based on settlements with the
applicable pool's administrator. Intrastate pooled revenues are settled on a
monthly basis with the Alaska Exchange Carrier Association (AECA) and are final
at the time of settlement. Participation in the AECA pool was discontinued
effective January 1, 1999. Interstate pooled revenues are settled on a monthly
basis with the National Exchange Carrier Association (NECA). The NECA
settlements may be adjusted for a period of up to twenty-four months. Interstate
traffic sensitive revenue is based on rates and charges defined in the Utility's
interstate tariff approved by the FCC. Interstate traffic sensitive revenue is
recognized when earned for both recurring and nonrecurring charges.

    To the extent that disputes arise over revenue settlement procedures, the
Utility's policy is to defer revenue collected until settlement methodologies
are resolved and finalized.

    MUNICIPAL UTILITY SERVICE ASSESSMENT

    The Municipal Utility Service Assessment (MUSA) is assessed by the
Municipality and is calculated based on the net book value of telephone plant in
the prior year. Net book value for each tax district is multiplied by the
current mill rate to determine the assessment. The Utility also pays a gross
receipt tax, which is 1.25% of gross operating revenues, excluding nonregulated
revenues.

    ADVERTISING

    Advertising costs are expensed in the period in which they are incurred.

    INCOME TAXES

    The Internal Revenue Code provides that gross income for tax purposes does
not include income accruing to a state or territory, or any political
subdivision thereof, which is derived from the exercise of any essential
governmental function or from any public utility. The Utility is a public
utility of the Municipality and is therefore exempt from federal and state
income taxes. ACI and its subsidiaries are exempt from federal and state income
taxes because ACI is a holding company owned 100% by the Utility.

    GASB NO. 27

    The Utility adopted GASB Statement No. 27, ACCOUNTING FOR PENSIONS BY STATE
AND LOCAL GOVERNMENTAL EMPLOYERS, during 1998. GASB No. 27 establishes standards
for the measurement, recognition and display of pension expense and related
liabilities, assets, note disclosure and applicable required supplementary
information in the financial reports of state and local governmental employers.
The impact of adopting GASB No. 27 was not material to the financial statements.

    IMPAIRMENT OF LONG-LIVED ASSETS

    The Utility has adopted FASB Statement No. 121, ACCOUNTING FOR THE
IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF.
Under the provisions of this statement, the Utility has evaluated its long-lived
assets for financial impairments and will continue to evaluate them if events or
changes in circumstance indicate the carrying amount of such assets may not be
fully recoverable.

    RECLASSIFICATIONS

    The 1993 revenue bond covenants require the establishment of reserves over a
five-year period equal to the maximum annual debt service on all outstanding
bonds. The 1994 refunding bond covenants require establishment of a reserve in
the amount of $9,750. The 1996 revenue bond covenants require an amount equal to
the lesser of $4,400 or the maximum annual debt service to be funded in equal
installments over four years. The 1997 revenue bond covenants require an amount
equal to the lessor of $2,500 or the maximum annual debt service to be funded in
equal installments over four years. The 1998 revenue bond covenants require an
amount equal to the lessor of $3,000 or the maximum annual debt service to be
funded in equal installments over four years. The revenue bond covenants further
stipulate that revenues less expenses will be equal to at least 1.4 times the
debt service requirements for that year. Expenses are defined as costs for
operation and maintenance of the system, excluding depreciation and MUSA for
each year. For the years ended December 31, 1998, 1997 and 1996, the Utility
complied with the revenue bond covenants.

(4) REFUNDING OF LONG-TERM OBLIGATIONS

    In 1994, the Utility issued refunding bond issues for the purpose of
redeeming certain bond issues when they become due or callable. The net proceeds
of the refunding bond issue were used to purchase US Government securities which
were deposited in an irrevocable trust with an escrow agent to provide all
future debt service payments on the refunded bonds. Since payment of these
advance refunded issues has been provided, as described above, neither the
liability nor the assets irrevocably pledged, including related interest income
and expense, are reflected in the accompanying financial statements.

    Defeased bonds as of December 31, 1998 total $11,390 for the 1990 issue.

(5) RETIREMENT PLANS

    Substantially all employees are covered by one of the following plans.

    INTERNATIONAL BROTHERHOOD OF ELECTRICAL WORKERS (IBEW) PLAN

    The IBEW Plan is a union sponsored defined benefit pension plan for members
of the IBEW #1547 Union. The Utility contributed $3.67 per compensable employee
hour to the Alaska Electrical Trust Fund in 1998, 1997 and 1996. Utility
contributions to this plan were $3,130, $3,379 and $3,608 for the years ended
December 31, 1998, 1997 and 1996, respectively. The hourly rate paid by the
Utility is determined by the collective bargaining process. The Utility's
obligation for IBEW employee retirement is limited to the amount paid to the
Alaska Electrical Trust Fund.

    STATE OF ALASKA PUBLIC EMPLOYEES' RETIREMENT SYSTEM PLAN

    As discussed in note 1, the Utility adopted the provisions of GASB Statement
No. 27, ACCOUNTING FOR PENSIONS BY STATE AND LOCAL GOVERNMENTAL EMPLOYERS (GASB
27), in 1998.

    STATE OF ALASKA PUBLIC EMPLOYEES' RETIREMENT SYSTEM

    A. PLAN DESCRIPTION

    The Utility contributes to the State of Alaska Public Employees' Retirement
System (PERS), a defined benefit, agent multiple-employer public employee
retirement system which was established and is administered by the State of
Alaska (State) to provide pension, postemployment healthcare, death and
disability benefits to eligible employees.

    All full-time Utility employees not covered by the IBEW Plan are eligible to
participate in PERS. Benefit and contribution provisions are established by
State law and may be amended only by the State Legislature.

    Each fiscal year, PERS issues a publicly available financial report that
includes financial statements and required supplementary information. That
report may be obtained by writing to the State of Alaska, Department of
Administration, Division of Retirement and Benefits, P.O. Box 110203, Juneau,
Alaska, 99811-0203 or by calling (907) 465-4460.

    B. FUNDING POLICY AND ANNUAL PENSION COST

    Employee contribution rates are 6.75% as required by State statute. The
funding policy for PERS provides for periodic employer contributions at
actuarially determined rates that, expressed as a percentage of annual covered
payroll, are sufficient to accumulate sufficient assets to pay

(6) OTHER EMPLOYEE BENEFITS

    The Municipality offers its employees, including employees of the Utility, a
deferred compensation plan (Plan) created in accordance with Internal Revenue
Code Section 457. The Plan, available to all Municipal employees, permits them
to defer a portion of their salary until future years. The deferred compensation
is not available to employees until termination, retirement, death or
unforeseeable emergency. It is the opinion of the Municipality's legal counsel
that the

Municipality has no liability for losses under the Plan but does have the duty
of due care that would be required of an ordinary prudent investor.

    The municipality believes that it is unlikely that it will use the assets to
satisfy the claims of general creditors in the future.

    In accordance with labor agreements, IBEW employees' medical/dental coverage
is provided through the Alaska Electrical Health and Welfare Trust Fund. Utility
contributions to this fund were $2,859, $3,143 and $2,888 for the years ended
December 31, 1998, 1997 and 1996, respectively.

</TABLE>

    The Utility is one of three members of a limited liability company, Alaskan
Choice Television, LLC (ACTV). ACTV has accumulated substantial losses since
inception and is not generating sufficient cash flow to sustain operations.
These factors, among others, indicate that ACTV may be unable to continue as a
going concern for a reasonable period of time. ACTV's continuation as a going
concern is dependent upon its ability to attain additional equity and debt
financing and achieve positive cash flow and profitability. ACTV is in
negotiation with a potential investor who will provide working capital. The
other two members of the limited liability company have agreed to sell their
interests to this investor. ACTV expects to complete this transaction in the
second quarter of 1999. Additionally, ACTV is in discussion with several
financial institutions to provide the necessary debt financing. Pursuant to
Statement of Financial Accounting Principles Board Opinion No. 18, "The Equity
Method of Accounting for Investments in Common Stock", the Utility assessed the
recoverability of its investment in ACTV during 1998 and adjusted the carrying
value of the investment to its estimated fair value resulting in a noncash
impairment loss of approximately $1,500.

(8) RELATED PARTY TRANSACTIONS

    INTRAGOVERNMENTAL CHARGES

    Certain general and administrative functions of the Municipality, including
data processing, workers' compensation insurance and medical/dental/life
insurance, are centralized and the related cost is allocated to the various
funds of the Municipality, including the Utility. Such costs allocated

to the Utility totaled $3,187, $3,672, and $3,204 for the years ended
December 31, 1998, 1997, and 1996, respectively.

    These costs are allocated to ATU from the Municipality of Anchorage through
an inter-governmental charge system ("IGC") based upon ATU's proportionate share
of certain cost drivers, such as manned positions, building square footage or
number of transactions processed, depending upon the type of cost being
allocated. Certain IGC's are based upon work orders for specific projects
between departments. Management believes that the methodology utilized is
reasonable. It is not practicable to quantify what such costs would have been on
a stand-alone basis.

(9) FAIR VALUE OF FINANCIAL INSTRUMENTS

    The fair value of a financial instrument represents the amount at which the
instrument could be exchanged in a current transaction between willing parties,
other than in a forced sale or liquidation. Significant differences can arise
between the fair value and carrying amount of financial instruments that are
recognized at historical cost amounts.

    The following methods and assumptions were used by the Utility in estimating
fair value disclosures for financial instruments:

        Cash, restricted investments, accounts receivable, accounts payable and
    accrued liabilities, accrued interest, customer deposits and accrued
    employee benefits--The carrying amounts at December 31, 1998 and 1997
    approximate the fair values due to the short maturity of these instruments.

        Long-term debt--The fair value of the Utility's long-term debt is
    estimated by discounting the future cash flows of the various instruments at
    rates currently available to the Utility for similar debt instruments of
    comparable maturities.

    The carrying amount of long-term debt and its estimated fair value at
December 31 are as follows:

corporation has the power to indemnify its officers, directors, employees and
agents (or persons serving in such positions in another entity at the request of
the corporation) against expenses, including attorney's fees, judgments, fines
or settlement amounts actually and reasonably incurred by them in connection
with the defense of any action by reason of being or having been directors or
officers, if such person shall have acted in good faith and in a manner
reasonably believed to be in or not opposed to the best interests of the
corporation (and, with respect to any criminal action, had no reasonable cause
to believe the person's conduct was unlawful), except that if such action shall
be by or in the right of the corporation, no such indemnification shall be
provided as to any claim, issue or matter as to which such person shall have
been judged to have been liable to the corporation unless and to the extent that
the Court of Chancery of the State of Delaware, or another court in which the
suit was brought, shall determine upon application that, in view of all of the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity. The Registrant's Certificate of Incorporation provides that the
Registrant will indemnify its officers and directors to the fullest extent
permitted by Delaware law.

    As permitted by Section 102 of the DGCL, the Registrant's Certificate of
Incorporation provides that no director shall be liable to the Registrant or its
stockholders for monetary damages for any breach of fiduciary duty as a director
other than (i) for breaches of the director's duty of loyalty to the Registrant
or its stockholders, (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (iii) for the
unlawful payment of dividends or unlawful stock purchases or redemptions under
Section 174 of the DGCL, or (iv) for any transaction from which the director
derived an improper personal benefit.

    The Underwriting Agreement is expected to provide that the Underwriters are
obligated, under certain circumstances, to indemnify directors, officers and
controlling persons of the Registrant

                                      II-1
<PAGE>
against certain liabilities, including liabilities under the Securities Act.
Reference is made to the form of Underwriting Agreement to be filed as
Exhibit 1.1 hereto.

    The Registrant maintains directors and officers liability insurance for the
benefit of its directors and certain of its officers.

ITEM 17. UNDERTAKINGS

    The undersigned Registrant hereby undertakes:

        (1) That for purposes of determining any liability under the Securities
    Act of 1933, the information omitted from the form of prospectus filed as
    part of this Registration Statement in reliance upon Rule 430A and contained
    in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1)
    or (4) or 497(h) under the Securities Act of 1933 shall be deemed to be part
    of this Registration Statement as of the time it was declared effective.

        (2) That for the purpose of determining any liability under the
    Securities Act of 1933, each post-effective amendment that contains a form
    of prospectus shall be deemed to be a new registration statement relating to
    the securities offered therein, and the offering of such securities at that
    time shall be deemed to be the initial BONA FIDE offering thereof.

        (3) To provide to the underwriters at the closing specified in the
    underwriting agreement certificates in such denominations and registered in
    such names as required by the underwriters to permit prompt delivery to each
    purchaser.

        (4) Insofar as indemnification for liabilities arising under the
    Securities Act of 1933 may be permitted to directors, officers and
    controlling persons of the Registrant pursuant to the foregoing provisions,
    or otherwise, the Registrant has been advised that in the opinion of the
    Securities and Exchange Commission such indemnification is against public
    policy as expressed in the Securities Act of 1933 and is, therefore,
    unenforceable. In the event that a claim for indemnification against such
    liabilities (other than the payment by the Registrant of expenses incurred
    or paid by a director, officer or controlling person of the Registrant in
    the successful defense of any action, suit or proceeding) is asserted by
    such director, officer or controlling person in connection with the
    securities being registered, the Registrant will, unless in the opinion of
    its counsel the matter has been settled by controlling precedent, submit to
    a court of appropriate jurisdiction the question whether such
    indemnification by it is against public policy as expressed in the
    Securities Act of 1933 and will be governed by the final adjudication of
    such issue.
