ITEM 1. BUSINESS
 
THE COMPANY
 
    United States Cellular Corporation (the "Company") provides cellular
telephone service to 1,710,000 customers through 134 majority-owned and managed
("consolidated") cellular systems serving approximately 16% of the geography and
approximately 9% of the population of the United States. Since 1985, when the
Company began providing cellular service in Knoxville, Tennessee, the Company
has expanded its cellular networks and customer service operations to cover 143
markets in 26 states as of December 31, 1997. In total, the Company now operates
eight market clusters, of which four have a total population of more than two
million, and each of which has a total population of more than one million.
Overall, 86% of the Company's 26.2 million population equivalents are in markets
which are consolidated, 2% are in managed but not consolidated markets and 12%
are in markets in which the Company holds an investment interest.
 
    The Company is the eighth largest cellular telephone company in the United
States, based on the aggregate number of population equivalents it owns. The
Company's corporate development strategy is to operate controlling interests in
cellular market licensees in areas adjacent to or in proximity to its other
markets, thereby building clusters of operating markets. Customers benefit from
larger service areas such as these, which provide longer uninterrupted service
and the ability to make outgoing calls and receive incoming calls within the
designated area without special roaming arrangements. In addition, the Company
anticipates that clustering will continue to provide the Company certain
economies in its capital and operating costs. As the number of opportunities for
outright acquisitions has decreased in recent years, and as the Company's
clusters have grown, the Company's focus has shifted toward exchanges and
divestitures of managed and investment interests which are considered less
essential to the Company's clustering strategy.
 
    The following table summarizes the status of the Company's interests in
cellular markets at December 31, 1997.

    PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995 SAFE HARBOR CAUTIONARY
                                   STATEMENT
 
    This Annual Report on Form 10-K, including exhibits, contains
"forward-looking" statements, as defined in the Private Securities Litigation
Reform Act of 1995, that are based on current expectations, estimates and
projections. Statements that are not historical facts, including statements
about the Company's beliefs and expectations, are forward-looking statements.
These statements contain potential risks and uncertainties; therefore, actual
results may differ materially. The Company undertakes no obligation to update
publicly any forward-looking statements whether as a result of new information,
future events or otherwise.
 
    Important factors that may affect these projections or expectations include,
but are not limited to: changes in the overall economy; changes in competition
in markets in which the Company operates; advances in telecommunications
technology; changes in the telecommunications regulatory environment; pending
and future litigation; availability of future financing; start-up of Personal
Communications Services ("PCS") operations; and unanticipated changes in growth
in cellular customers, penetration rates, churn rates and the mix of products
and services offered in the Company's markets. Readers should evaluate any
statements in light of these important factors.
 
PROPOSED TDS CORPORATE RESTRUCTURING
 
    In December 1997, the Company received a proposal from TDS to acquire all of
the issued and outstanding Common Shares of the Company not already owned by TDS
(the "Merger"). The offer was made in connection with, and is subject to TDS
shareholder approval of and the effectiveness of, TDS's proposed corporate
restructuring. The Board of Directors of TDS (the "TDS Board") has adopted a
proposal which, if approved by TDS shareholders and implemented by the TDS
Board, would authorize the TDS Board to issue three new classes of common stock
and change the state of incorporation of TDS from Iowa to Delaware (the
"Tracking Stock Proposal"). The three new classes of stock are intended to
separately reflect the performance of TDS's cellular telephone, landline
telephone and personal communications services businesses ("Tracking Stocks").
 
    Under the Tracking Stock Proposal, one of the three new classes of common
stock created by TDS would be designated as United States Cellular Group Common
Shares (the "Cellular Group Shares"). The Cellular Group Shares, when issued,
are intended to reflect the separate performance of the United States Cellular
Group (the "Cellular Group"), which consists of TDS's interest in United States
Cellular Corporation.

<PAGE>
    Subject to the approval of the Tracking Stock Proposal by shareholders, TDS
intends to, among other things, issue Cellular Group Shares in exchange for all
of the Common Shares of the Company which are not currently owned by TDS,
subject to approval by the Company's Board of Directors and shareholders.
 
    In January 1998, the Company's Board of Directors created a special
committee of the Board (the "Special Committee") to review the proposal from
TDS. The Special Committee, consisting of one independent director of the
Company, has engaged a financial advisor and legal advisor to assist in
reviewing the proposal. The Special Committee will consider how the Company
should respond to the TDS proposal, take the steps it deems appropriate to
respond to the TDS proposal and, at such time as it considers it appropriate,
report its recommendations to the Company's Board of Directors.
 
    Subsequent to shareholder approval of the Tracking Stock Proposal, TDS
intends to terminate certain intercompany agreements between TDS and the
Company. Thereafter, some or all of the policies between TDS and the Company
would be determined solely by methods that management believes to be reasonable.
Many of such policies would continue the arrangements which presently exist
between TDS and the Company pursuant to the intercompany agreements, but TDS
would have no contractual obligation to continue such policies after the
intercompany agreements have been terminated. The TDS Board currently intends to
retain future earnings, if any, for the development of the business of the
Cellular Group and does not anticipate paying dividends on the Cellular Group
Shares in the foreseeable future.
 
    On December 29, 1997, an individual who claims to be a holder of the
Company's Common Shares filed a putative class action complaint on behalf of
common stockholders of the Company in the Court of Chancery of the State of
Delaware in New Castle County. The complaint names as defendants TDS, the
Company and the directors of the Company. The complaint alleges a breach of
fiduciary duties by the defendants and seeks to have the Merger enjoined or, if
it is consummated, to have it rescinded and to recover unspecified damages, fees
and expenses. A virtually identical complaint has been filed by a second
individual. None of the defendants have been served with this complaint. The
Company intends to vigorously defend against these lawsuits.
 
CELLULAR TELEPHONE OPERATIONS
 
    THE CELLULAR TELEPHONE INDUSTRY.  Cellular telephone technology provides
high-quality, high-capacity communications services to in-vehicle and hand-held
portable cellular telephones. Cellular technology is a major improvement over
earlier mobile telephone technologies. Cellular telephone systems are designed
for maximum mobility of the customer. Access is provided through system
interconnections to local, regional, national and world-wide telecommunications
networks. Cellular telephone systems also offer a full range of ancillary
services such as conference calling, call-waiting, call-forwarding, voice mail,
facsimile and data transmission.
 
    Cellular telephone systems divide each service area into smaller geographic
areas or "cells." Each cell is served by radio transmitters and receivers
operating on discrete radio frequencies licensed by the FCC. All of the cells in
a system are connected to a computer-controlled Mobile Telephone Switching
Office ("MTSO"). The MTSO is connected to the conventional ("landline")
telephone network and potentially other MTSOs. Each conversation on a cellular
phone involves a transmission over a specific set of radio frequencies from the
cellular phone to a transmitter/receiver at a cell site. The transmission is
forwarded from the cell site to the MTSO and from there may be forwarded to the
landline telephone network to complete the call. As the cellular telephone moves
from one cell to another, the MTSO determines radio signal strength and
transfers ("hands off") the call from one cell to the next. This hand-off is not
noticeable to either party on the phone call.
 
    The FCC currently grants only two licenses to provide cellular telephone
service in each market. However, competition for customers includes competing
communications technologies such as conventional landline and mobile telephone,
Specialized Mobile Radio ("SMR") systems and radio paging. PCS has become
available in many areas of the United States, including the Company's markets,
and the Company expects PCS operators to complete initial deployment of PCS in
portions of all of the Company's clusters by the end of 1998. Additionally,
emerging technologies such as Enhanced
 
                                                                               5
<PAGE>
Specialized Mobile Radio ("ESMR") and mobile satellite communication systems may
prove to be competitive with cellular service in the future in some or all of
the Company's markets.
 
    The services available to cellular customers and the sources of revenue
available to cellular system operators are similar to those provided by
conventional landline telephone companies. Customers may be charged a separate
fee for system access, airtime, long-distance calls and ancillary services.
Cellular system operators often provide service to customers of other operators'
cellular systems while the customers are temporarily located within the
operators' service areas. Customers using service away from their home system
are called "roamers." Roaming is available because technical standards require
that analog cellular telephones be compatible in all market areas in the United
States. The system that provides the service to these roamers will generate
usage revenue. Many operators, including the Company, charge premium rates for
this roaming service.
 
    There are a number of recent technical developments in the cellular
industry. Currently, while most of the MTSOs process information digitally, on
certain cellular systems the radio transmission is done on an analog basis.
During 1992, a new transmission technique was approved for implementation by the
cellular industry. Time Division Multiple Access ("TDMA") technology was
selected as one industry standard by the cellular industry and has been deployed
in several markets, including the Company's operations in portions of several
clusters. Another digital technology, Code Division Multiple Access ("CDMA"), is
also being deployed by the Company in portions of certain clusters. Digital
radio technology offers several advantages, including greater privacy, less
transmission noise, greater system capacity and potentially lower incremental
costs for additional customers. The conversion from analog to digital radio
technology is continuing on an industry-wide basis; however, this process is
expected to take a number of years. PCS operators have deployed systems based on
versions of TDMA and CDMA technology and a third digital technology, Global
Systems for Mobile Communications ("GSM"), in the markets where they have begun
operations.
 
    The cellular telephone industry is characterized by high initial fixed
costs. Accordingly, if and when revenues less variable costs exceed fixed costs,
incremental revenues should yield an operating profit. The amount of profit, if
any, under such circumstances is dependent on, among other things, prices and
variable marketing costs which in turn are affected by the amount and extent of
competition. Until technological limitations on total capacity are approached,
additional cellular system capacity can normally be added in increments that
closely match demand and at less than the proportionate cost of the initial
capacity.
 
    THE COMPANY'S OPERATIONS.  From its inception in 1983 until 1993, the
Company was principally in a start-up phase. Until that time, the Company's
activities had been concentrated significantly on the acquisition of interests
in cellular licensees and on the construction and initial operation of cellular
systems. The development of a cellular system is capital-intensive and requires
substantial investment prior to and subsequent to initial operation. The Company
experienced operating losses and net losses from its inception until 1993.
During the past four years, the Company generated operations-driven net income
and has significantly increased its operating cash flows during that time.
Management anticipates further growth in cellular units in service and revenues
as the Company continues to expand through internal growth. Marketing and system
operations expenses associated with this expansion may reduce the rate of growth
in operating cash flows and operating income during the period of additional
growth. In addition, the Company anticipates that the seasonality of revenue
streams and operating expenses may cause the Company's operating income to vary
from quarter to quarter.
 
    While the Company produced operating income and net income during the last
four years, changes in any of several factors may reduce the Company's growth in
operating income and net income over the next few years. These factors include:
(i) the growth rate in the Company's customer base; (ii) the usage and pricing
of cellular services; (iii) the churn rate; (iv) the cost of providing cellular
services, including the cost of attracting new customers; (v) continued
competition from PCS and other emerging technologies; and (vi) continuing
technological advances which may provide additional competitive alternatives to
cellular service.
 
    The Company is building a substantial presence in selected geographic areas
throughout the United States where it can efficiently integrate and manage
cellular telephone systems. Its cellular interests include regional market
clusters in the following areas: Wisconsin/Illinois/Indiana, Iowa/

Missouri, Eastern North Carolina/South Carolina, West
Virginia/Maryland/Pennsylvania/Ohio, Virginia, Washington/Oregon/Idaho,
Oregon/California, Maine/New Hampshire/Vermont, Florida/Georgia,
Oklahoma/Missouri/Kansas, Texas/Oklahoma, Eastern Tennessee/Western North
Carolina and Southwestern Texas. See "The Company's Cellular Interests." The
Company has acquired its cellular interests through the wireline application
process (17%), including settlements and exchanges with other applicants, and
through acquisitions (83%), including acquisitions from TDS and third parties.
 
CELLULAR SYSTEMS DEVELOPMENT
 
    ACQUISITIONS.  During the last five years, the Company has expanded its
size, particularly in contiguous or adjacent markets, through acquisitions which
have been aimed at strengthening the Company's position in the cellular
industry. This growth has resulted primarily from acquisitions of interests in
mid-sized and rural markets and has been based on obtaining interests with
rights to manage the underlying market.
 
    Including acquisitions of cellular interests from TDS, the Company has
increased its population equivalents by 17%, from approximately 22.5 million at
December 31, 1992, to approximately 26.2 million at December 31, 1997. Markets
managed by the Company have increased from 116 markets at December 31, 1992 to
143 markets at December 31, 1997. As of December 31, 1997, 88% of the Company's
population equivalents represented interests in markets the Company manages
compared to 75% at December 31, 1992.
 
    Recently, the pace of acquisitions has slowed as industry-wide consolidation
has reduced the number of markets available for acquisition. The Company's
population equivalents grew at a compound annual rate of just 3% over the last
five years due to the increased number of exchange and divestiture transactions
in the past few years.
 
    The Company may continue to make opportunistic acquisitions or exchanges in
markets that further strengthen its market clusters and in other attractive
markets. The Company also seeks to acquire minority interests in markets where
it already owns the majority interest. There can be no assurance that the
Company, or TDS for the benefit of the Company, will be able to negotiate
additional acquisitions or exchanges on terms acceptable to it or that
regulatory approvals, where required, will be received. The Company plans to
retain minority interests in certain cellular markets which it believes will
earn a favorable return on investment. Other minority interests may be exchanged
for interests in markets which enhance the Company's market clusters or may be
sold for cash or other consideration. The Company also continues to evaluate the
disposition of certain managed interests which are not essential to its
corporate development strategy.
 
    The Company, or TDS for the benefit of the Company, has historically
negotiated acquisitions of cellular interests from third parties primarily in
consideration for the Company's Common Shares or TDS's equity securities.
Cellular interests acquired by TDS in these transactions have been assigned to
the Company. At that time, the Company reimbursed TDS for the value of TDS
securities issued in such transactions, generally by issuing Common Shares to
TDS or by increasing the balance under the Company's Revolving Credit Agreement
with TDS in amounts equal to the value of TDS securities delivered at the time
the acquisitions were completed. The fair market value of the Company's
securities issued to TDS in connection with these transactions was equal to the
fair market value of the TDS securities delivered in the transactions and was
determined at the time the transactions were completed.
 
    In the past four years, the Company has also negotiated substantial
divestitures and exchanges of cellular interests with third parties. The
consideration received from these divestitures of non-strategic markets has
primarily been cash, which has been used to reduce debt or for general corporate
purposes. The exchanges have included the divestiture of controlling interests
in non-strategic markets in exchange for controlling interests in markets which
further enhance the Company's clusters.
 
    COMPLETED ACQUISITIONS.  During 1997, the Company, or TDS for the benefit of
the Company, purchased majority interests in two markets and several additional
minority interests, representing approximately 534,000 population equivalents.
The total consideration paid for these purchases, primarily in the form of cash
(including cash borrowed under the Revolving Credit Agreement with TDS)
 
                                                                               7
<PAGE>
and the Company's Common Shares issued to TDS to reimburse TDS for the value of
TDS Common Shares issued to third parties, totaled $81.4 million.
 
    COMPLETED DIVESTITURES AND EXCHANGES.  During 1997, the Company sold a
majority interest in one market and minority interests in two other markets,
representing approximately 358,000 population equivalents, for an aggregate
consideration of $54.5 million in cash and receivables. The two minority
interests involved interests the Company had previously acquired from TDS
pursuant to an agreement between the two companies signed in June 1996.
 
    Also during 1997, the Company completed an exchange with BellSouth
Corporation ("BellSouth"). Pursuant to the exchange, the Company received
majority interests representing approximately 4.0 million population equivalents
in exchange for majority interests representing approximately 2.0 million
population equivalents, minority interests representing approximately 1.2
million population equivalents and a net amount of $86.7 million in cash. The
majority interests the Company received are in 12 markets adjacent to its
Iowa/Missouri and Wisconsin/Illinois/Indiana clusters.
 
    PENDING ACQUISITIONS.  At December 31, 1997, the Company had entered into
agreements with third parties to acquire a majority interest in one market and a
minority interest in a market in which the Company owns a majority interest,
representing approximately 410,000 population equivalents, for $51.3 million in
cash. If the majority interest is acquired as expected, the Company will
subsequently sell that interest to BellSouth for cash.
 
    PENDING DIVESTITURES.  At December 31, 1997, the Company had entered into
agreements with AirTouch Communications, Inc. ("AirTouch") to divest minority
interests in nine markets, representing 759,000 population equivalents. In
exchange, the agreements provided that the Company will receive approximately
4.0 million shares of AirTouch stock and cash totaling $54.2 million. In
addition, the Company will receive approximately $27.0 million in cash from TDS
pursuant to a contract right termination agreement entered into between the
Company and TDS. This agreement is related to two interests which are to be sold
directly by TDS to AirTouch and which were to be acquired by the Company as part
of the June 1996 agreement between the Company and TDS. The contract right
termination agreement will enable the Company to receive cash equal to the value
of the gain the Company would have realized had it purchased the interests from
TDS and sold them to AirTouch under terms similar to those in the agreement
between TDS and AirTouch.
 
    Additionally, the Company has entered into an agreement to sell its minority
interests in two other markets, representing approximately 176,000 population
equivalents, for $37.6 million in cash. The Company expects these pending
transactions to be completed during the first half of 1998. The Company
anticipates that it will record significant book gains on these divestitures
when the transactions are completed.
 
    The Company maintains shelf registration of its Common Shares and Preferred
Stock under the Securities Act of 1933 for issuance specifically in connection
with acquisitions.
 
    The Company is a majority-owned subsidiary of TDS. TDS owns 81.1% of the
combined total of the outstanding Common Shares and Series A Common Shares of
the Company and controls 95.6% of the combined voting power of both classes of
common stock. The Company benefits from the extensive telecommunications
industry experience of TDS, which also operates a telephone business and is
developing its PCS business.
 
CELLULAR INTERESTS AND CLUSTERS
 
    The Company operates clusters of adjacent cellular systems in nearly all of
its markets, enabling its customers to benefit from larger service areas than
otherwise possible. Where the Company offers wide-area coverage, its customers
enjoy uninterrupted service within the designated area. Customers may also make
outgoing calls and receive incoming calls within this area without special
roaming arrangements. In addition to benefits to customers, clustering also has
provided to the Company certain economies in its capital and operating costs.
These economies are made possible through increased sharing of facilities,
personnel and other costs and have resulted in a reduction of the Company's per
customer cost of service. The extent to which the Company benefits from these
revenue enhancements
 
8
<PAGE>
and economies of operation is dependent on market conditions, population size of
each cluster and engineering considerations.
 
    The Company may continue to make opportunistic acquisitions and exchanges
which will complement its established market clusters. From time to time, the
Company may also consider exchanging or selling its interests in markets which
do not fit well with its long-term strategies.
 
    The Company owned interests in cellular telephone systems in 192 markets at
December 31, 1997, representing 26.2 million population equivalents. Including
the effect of the 11 minority interests to be sold during 1998, the Company
owned or had the right to acquire 181 markets, representing 25.3 million pops,
at December 31, 1997. The following table summarizes the growth in the Company's
population equivalents in recent years and the development status of these
population equivalents.

presented therein lists clusters of markets that the Company manages. The
Company's market clusters show the areas in which the Company is currently
focusing its development efforts. These clusters have been devised with a
long-term goal of allowing delivery of cellular service to areas of economic
interest and along corridors of economic activity. The number of population
equivalents represented by the Company's cellular interests may have no direct
relationship to the number of potential cellular customers or the revenues that
may be realized from the operation of the related cellular systems.

(1) Interests under these agreements are expected to be acquired at the time
    specified therein, following the satisfaction of customary closing
    conditions.
 
(2) These markets have been partitioned into more than one licensed area. The
    1997 population, percentage ownership and number of population equivalents
    shown are for the licensed areas within the markets in which the Company
    owns an interest.
 
(3) The Company owns 80% of the entity which owns and operates this market but
    has only a 49% interest in the earnings and profits. Pursuant to a
    definitive agreement, the Company has rights to acquire the remaining 20% of
    the equity and 51% of the earnings and profits of this entity.
 
    SYSTEM DESIGN AND CONSTRUCTION.  The Company designs and constructs its
systems in a manner it believes will permit it to provide high-quality service
to mobile, transportable and portable cellular telephones, generally based on
market and engineering studies which relate to specific markets. Engineering
studies are performed by Company personnel or independent engineering firms. The
Company's switching equipment is digital, which reduces noise and crosstalk and
is capable of interconnecting in a manner which reduces costs of operation.
While digital microwave interconnections are typically made between the MTSO and
cell sites, primarily analog radio transmission is used between cell sites and
the cellular telephones themselves.
 
    In accordance with its strategy of building and strengthening market
clusters, the Company has selected high capacity digital cellular switching
systems that are capable of serving multiple markets through a single MTSO. The
Company's cellular systems are designed to facilitate the installation of
equipment which will permit microwave interconnection between the MTSO and the
cell site. The Company has implemented such microwave interconnection in most of
the cellular systems it manages. In other systems in which the Company owns a
majority interest and where it is believed to be cost-efficient, such microwave
technology will also be implemented. Otherwise, such systems will rely upon
landline telephone connections or microwave links owned by others to link cell
sites with the MTSO. Although the installation of microwave network
interconnection equipment requires a greater initial capital investment, a
microwave network enables a system operator to avoid the current and future
charges associated with leasing telephone lines from the landline telephone
company, while generally improving system reliability. In addition, microwave
facilities can be used to connect separate cellular systems to allow shared
switching, which reduces the aggregate cost of the equipment necessary to
operate both systems.
 
    The Company expanded its internal network in 1996 to encompass all of its
managed markets. This network provides automatic call delivery for the Company's
customers and handoff between adjacent markets. The network has also been
extended through links with certain systems operated by several other carriers,
including GTE, AirTouch/US West, Ameritech, BellSouth, Centennial Cellular
Corp., Southwestern Bell, AT&T Wireless Communications, Vanguard Cellular
Systems and others. Additionally, the Company has implemented certain Signal
Transfer Points which have allowed it to interconnect efficiently with network
providers such as Illuminet and the North American Cellular Network.
 
14
<PAGE>
    The Company plans to integrate the systems in the markets acquired in the
exchange with BellSouth into its internal network as quickly as possible. This
may involve changing out certain system equipment and replacing it with new
equipment which will allow for more efficient networking.
 
    During 1997, the Company extended the network for its customers through
interconnection with additional system operators for call delivery and hand-off.
This expanded network increases the area in which customers can automatically
receive incoming calls, and should further reduce the incidence of "tumbling"
electronic serial number fraud due to the pre-call validation feature of
networked systems. In addition, the extension of these networks will allow for
the termination of wireless-to-wireless traffic without the inherent costs that
are otherwise incurred if this traffic is routed through the landline network.
 
    Management believes that currently available technologies will allow
sufficient capacity on the Company's networks to meet anticipated demand over
the next few years.
 
COSTS OF SYSTEM CONSTRUCTION AND FINANCING
 
    Construction of cellular systems is capital-intensive, requiring substantial
investment for land and improvements, buildings, towers, MTSOs, cell site
equipment, microwave equipment, engineering and installation. The Company,
consistent with FCC control requirements, uses primarily its own personnel to
engineer and oversee construction of each cellular system it owns and operates.
In so doing, the Company expects to improve the overall quality of its systems
and to reduce the expense and time required to make them operational.
 
    The costs (exclusive of license costs) of the systems in which the Company
owns an interest have historically been financed through capital contributions
or intercompany loans from the Company to the entities owning the systems, and
through certain vendor financing. In recent years, these funding requirements
have been met with cash generated from operations, proceeds from debt and equity
offerings and proceeds from the sales of cellular interests.
 
MARKETING
 
    The Company's marketing plan is centered around rapid penetration of its
market clusters, increasing customer awareness of cellular service and reducing
churn through both the building of brand awareness and the implementation of
marketing programs. The marketing plan stresses the value of the Company's
service offerings and incorporates combinations of rate plans and cellular
telephone equipment which are designed to meet the needs of a variety of
customer segments and their usage patterns. The Company's distribution channels
include direct sales personnel, agents and retail service centers in the vast
majority of its markets. The retail locations are Company-owned and managed and
are designed to market cellular service to the consumer segment in a familiar
setting. In late 1996, the Company implemented its new site on the WorldWideWeb
to support its marketing efforts and to be a future distribution channel.
Customers may now order the Company's service through this Website.
 
    The Company manages each cluster of markets from an administrative office
with a local staff, including sales, customer service, engineering and in some
cases installation personnel. Direct sales consultants market cellular service
to business customers throughout each cluster. Retail associates work out of the
retail locations and market cellular service primarily to the consumer and small
business segment. The Company maintains an ongoing training program to improve
the effectiveness of sales consultants and retail associates by focusing their
efforts on obtaining customers and maximizing the sale of high-user packages.
These packages provide for customers to obtain a minimum amount of usage at
discounted rates per minute, at fixed prices which are charged even if usage
falls below a defined monthly minimum amount.
 
    The Company continues to expand its relationships with agents, dealers and
non-Company retailers to obtain customers. Agents and dealers are independent
business people who obtain customers for the Company on a commission basis. The
Company's agents are generally in the business of selling cellular telephones,
cellular service packages and other related products. The Company's dealers
include car stereo companies and other companies whose customers are also
potential cellular customers. The non-Company retailers include car dealers,
major appliance dealers, office supply dealers and mass merchants.
 
                                                                              15
<PAGE>
    The Company opened its first retail locations in late 1993, expanding to 260
stand-alone retail stores by the end of 1997. These Company-owned and operated
businesses utilize rental facilities in high-traffic areas. The Company has
implemented a uniform appearance in these stores, with all having similar
displays and layouts. The retail centers' hours of business match those of the
retail trade in the local marketplace, often staying open on weekends and later
in the evening than a typical business supplier. To fully serve customer needs,
these stores sell accessories to complement the phones and services the Company
has traditionally provided. During 1996, the Company further expanded its retail
presence by opening smaller retail kiosks within other larger merchandisers and
grocery stores. At December 31, 1997, the Company had opened over 140 "stores
within a store," primarily in Wal-Mart locations.
 
    In addition to its own retail centers, the Company actively pursues national
retail accounts, as agents of the Company, which yield new customer additions in
multiple markets. Agreements have been entered into with such national
distributors as Ford Motor Company, General Motors, Radio Shack, Best Buy,
Circuit City, Staples, Office Depot and Sears, Roebuck & Co. in certain of the
Company's markets. Upon the sale of a cellular telephone by one of these
national distributors, the Company receives, often exclusively within the
territories served, the resulting cellular customer.
 
    The Company uses a variety of direct mail, billboard, radio, television and
newspaper advertising to stimulate interest by prospective customers in
purchasing the Company's cellular service and to establish familiarity with the
Company's name. In 1997, the Company increased its focus on brand advertising,
using the tag line "The Way People Talk Around Here"(SM) to promote the United
States Cellular-TM- brand. Advertising is directed at gaining customers,
improving customers' awareness of the United States Cellular brand, increasing
existing customers' usage and increasing the public awareness and understanding
of the cellular services offered by the Company. The Company attempts to select
the advertising and promotion media that are most appealing to the targeted
groups of potential customers in each local market. The Company utilizes local
advertising media and public relations activities and establishes programs to
enhance public awareness of the Company, such as providing telephones and
service for public events and emergency uses.
 
    The following table summarizes, by operating cluster, the total population,

CUSTOMERS AND SYSTEM USAGE
 
    Cellular customers come from a wide range of occupations. They typically
include a large proportion of individuals who work outside of their offices such
as people in the construction, real estate, wholesale and retail distribution
businesses and professionals. Increasingly, the Company is providing cellular
service to consumers and to customers who use their cellular telephones for
security purposes. Although some of the Company's customers still use in-vehicle
cellular telephones, most new customers
 
16
<PAGE>
are selecting portable cellular telephones. These units have become more compact
and fully featured as well as more attractively priced, and they appeal to newer
segments of the customer population.
 
    The Company's cellular systems are used most extensively during normal
business hours between 7:00 am and 6:00 pm. On average, the local retail
customers in the Company's consolidated markets used their cellular systems
approximately 103 minutes per unit each month and generated retail revenue of
approximately $36 per month during 1997, compared to 107 minutes and $40 per
month in 1996. Revenue generated by roamers, together with local retail, toll
and other revenues, brought the Company's total average monthly service revenue
per customer unit in consolidated markets to $54 during 1997. Average monthly
service revenue per customer unit decreased approximately 15% during 1997. This
decrease is related to the industry-wide trend of newer customers tending to use
fewer minutes during peak business hours, which has reduced the average local
retail revenue per minute, and to the declining contribution of inbound roaming
revenue per customer. The Company believes that its customer base is growing
faster than that of the cellular industry as a whole, which has a dilutive
effect on inbound roaming revenue per customer. The Company anticipates that
average monthly service revenue per customer unit will continue to decline as
its distribution channels provide additional customers who generate lower
revenue per local minute of use and as roaming revenues grow more slowly.
However, this effect is more than offset by the Company's increasing number of
customers; therefore, the Company expects total revenues to continue to grow for
the next few years.
 
    In addition to revenue from local retail customers, the Company generates
revenue from roaming customers and other services. The Company's roaming service
allows a customer to place or receive a call in a cellular service area away
from the customer's home service area. The Company has entered into "roaming
agreements" with operators of other cellular systems covering virtually all
systems in the United States and Canada. These agreements offer customers the
opportunity to roam in these systems. These reciprocal agreements automatically
pre-register the customers of the Company's systems in the other carriers'
systems. Also, a customer of a participating system roaming (i.e., travelling)
in a Company market where this arrangement is in effect is able to make and
receive calls on the Company's system. The charge for this service is typically
at premium rates and is billed by the Company to the customer's home system,
which then bills the customer. The Company has entered into agreements with
other cellular carriers to transfer roaming usage at agreed-upon rates. In some
instances, based on competitive factors, the Company may charge a lower amount
to its customers than the amount actually charged to the Company by another
cellular carrier for roaming.

market penetration in the Company's managed operations.

PRODUCTS AND SERVICES
 
    CELLULAR TELEPHONES AND INSTALLATION.  There are a number of different types
of cellular telephones, all of which are currently compatible with cellular
systems nationwide. The Company offers a full range of vehicle-mounted,
transportable and hand-held portable cellular telephones. Features offered in
some of the cellular telephones include hands-free calling, repeat dialing, horn
alert and others.
 
    The Company negotiates volume discounts from its cellular telephone
suppliers. The Company discounts cellular telephones to meet competition or to
stimulate sales by reducing the cost of becoming a cellular customer. In these
instances, where permitted by law, customers are generally required to sign a
service contract with the Company. The Company also cooperates with cellular
equipment manufacturers in local advertising and promotion of cellular
equipment.
 
    The Company has established service and/or installation facilities in many
of its local markets to ensure quality installation and service of the cellular
telephones it sells. These facilities allow the Company to improve its service
by promptly assisting customers who experience equipment problems. Additionally,
the Company maintains a repair facility in Tulsa, Oklahoma, which handles more
complex service and repair issues.
 
    CELLULAR SERVICES.  The Company's customers are able to choose from a
variety of packaged pricing plans which are designed to fit different calling
patterns. The Company has developed and introduced its new consumer line of
products under the CarryPhone brand. These products include a) Express, a
pre-packaged phone plus price plan aimed at the convenience buyer; b)
TalkTracker, a cellular phone with usage prepaid; and c) Home and Away, a
combination cordless and cellular phone in a single package. The Company's
customer bills typically show separate charges for custom-calling features,
airtime in excess of the packaged amount, and toll calls. Custom-calling
features provided by the Company include wide-area call delivery, call
forwarding, call waiting, three-way calling and no-answer transfer. The Company
also offers a voice message service in many of its markets. This service, which
functions like a sophisticated answering machine, allows customers to receive
messages from callers when they are not available to take calls.
 
REGULATION
 
    REGULATORY ENVIRONMENT.  The operations of the Company are subject to FCC
and state regulation. The cellular telephone licenses held by USM are granted by
the FCC for the use of radio frequencies and are an important component of the
overall value of the assets of the Company. The construction, operation and
transfer of cellular systems in the United States are regulated to varying
degrees by the FCC pursuant to the Communications Act of 1934 (the
"Communications Act"). In 1996, Congress enacted the Telecommunications Act of
1996 (the "1996 Act"), which amended the Communications Act. The 1996 Act
mandates significant changes in existing telecommunications rules and policies
to promote competition, ensure the availability of telecommunications services
to all parts of the nation and to streamline regulation of the
telecommunications industry to remove regulatory burdens as competition
develops. The FCC has promulgated regulations governing construction and
operation of cellular systems, licensing (including renewal of licenses) and
technical standards for the provision of cellular telephone service under the
Communications Act, and is implementing the legislative objectives of the 1996
Act, as discussed below.
 
    LICENSING.  For cellular telephone licensing purposes, the FCC has divided
the United States into separate geographic markets (MSAs and RSAs). In each
market, the allocated cellular frequencies are divided into two equal blocks.
During the application process, the FCC reserved one block of frequencies for
nonwireline applicants and another block for wireline applicants. Subject to FCC
approval, a cellular system may be sold to either a wireline or nonwireline
entity, but no entity which controls a cellular system may own an interest in
another cellular system in the same MSA or RSA.
 
    The completion of acquisitions involving the transfer of control of a
cellular system requires prior FCC approval. Acquisitions of minority interests
generally do not require FCC approval. Whenever FCC approval is required, any
interested party may file a petition to dismiss or deny the application for
approval of the proposed transfer.
 
18
<PAGE>
    The FCC must be notified each time an additional cell is constructed which
enlarges the service area of a given market. The FCC's rules also generally
require persons or entities holding cellular construction permits or licenses to
coordinate their proposed frequency usage with neighboring cellular licensees in
order to avoid electrical interference between adjacent systems. The height and
power of base stations in the cellular system are regulated by FCC rules, as are
the types of signals emitted by these stations. In addition to regulation by the
FCC, cellular systems are subject to certain Federal Aviation Administration
("FAA") regulations with respect to the siting and construction of cellular
transmitter towers and antennas as well as local zoning requirements.
 
    Beginning in 1996, the FCC has also imposed a requirement that all licensees
register and obtain FCC registration numbers for all of their antenna towers
which require prior FAA clearance. The Company is currently engaged in this
registration process. All new towers must be registered at the time of
construction and existing towers are being registered on a staggered
state-by-state basis, to be concluded in May 1998.
 
    Beginning in October 1997, cellular systems, which previously were
"categorically excluded" from having to evaluate their facilities to ensure
their compliance with federal "radio frequency" (RF) radiation requirements,
were made subject to those requirements (cellular towers of less than 10 meters
in height, building-mounted antennae and cellular telephones). After October
1997, all new cellular facilities must be in compliance when they are brought
into service. Existing facilities must be brought into compliance with the
requirements when their licenses are renewed. The Company believes that the
great majority of its existing facilities already comply with the requirements,
that the remainder will be brought into compliance as required and that the
cellular telephones it sells comply with the standards.
 
    Initial cellular telephone licenses were granted tor ten-year periods. The
FCC has established standards for conducting comparative renewal proceedings
between a cellular licensee seeking renewal of its license and challengers
filing competing applications. The FCC has: (i) established criteria for
comparing the renewal applicant to challengers, including the standards under
which a renewal expectancy will be granted to the applicant seeking license
renewal; (ii) established basic qualifications standards for challengers; and
(iii) provided procedures for preventing possible abuses in the comparative
renewal process. The FCC has concluded that it will award a renewal expectancy
if the licensee has (i) provided "substantial" performance, which is defined as
"sound, favorable and substantially above a level of mediocre service just
minimally justifying renewal," and (ii) complied with FCC rules, policies and
the Communications Act. If a renewal expectancy is awarded to an existing
licensee, its license is renewed and competing applications are not considered.
 
    The Company's Tulsa and Knoxville licenses were renewed in 1995, and the
Company's Des Moines, Iowa; Peoria, Illinois; and Roanoke, Virginia licenses
were renewed in 1996. In September 1997, the Company filed license renewal
applications for its Davenport, Iowa; Tallahassee, Florida; Asheville, North
Carolina; Manchester, New Hampshire; Columbia, Missouri; Wichita Falls, Texas;
Gainesville, Florida; Lewiston, Maine; Joplin, Missouri; Cedar Rapids, Iowa; La
Crosse, Wisconsin; Bangor, Maine; Fort Pierce, Florida; Victoria, Texas;
Evansville, Indiana; and Owensboro, Kentucky licenses. Those applications were
unopposed. On October 30, 1997, the Company assigned its Evansville and
Owensboro licenses to a subsidiary of BellSouth as part of the exchange
transaction between the two companies. As part of the same transaction,
BellSouth assigned its Appleton, Wisconsin; Rockford, Illinois; Green Bay,
Wisconsin; and Janesville, Wisconsin licenses to the Company. All of those
licenses were renewed in January 1998.
 
    The Company conducts and plans to conduct its operations in accordance with
all relevant FCC rules and regulations and anticipates being able to qualify for
a renewal expectancy in its upcoming renewal filings. Accordingly, the Company
believes that current regulations will have no significant effect on its
operations and financial condition. However, changes in the regulation of
cellular operators or their activities and of other mobile service providers
could have a material adverse effect on the Company's operations.
 
    The FCC has also provided that five years after the initial licenses are
granted, unserved areas within markets previously granted to licensees may be
applied for by both wireline and non-wireline entities and by third parties.
Accordingly, many unserved area applications have been filed by the Company and
others. The Company's strategy with respect to system construction in its
markets has been and will be to build cells covering areas within such markets
that the Company considers economically feasible to
 
                                                                              19
<PAGE>
serve or might conceivably wish to serve and to do so within the five-year
period following issuance of the license. In cases where applications for
unserved areas are filed which are mutually exclusive and would result in
overlapping service areas, the FCC decides between the competing applicants by
an auction process.
 
    Pursuant to 1993 amendments to the Communications Act, cellular service is
classified as a Commercial Mobile Radio Service ("CMRS"), in that it is service
offered to the public, for a fee, which is interconnected to the public switched
telephone network. The FCC has determined that it will forebear from requiring
CMRS carriers to comply with a number of statutory provisions otherwise
applicable to common carriers, such as the filing of tariffs.
 
    RECENT EVENTS.  There are certain regulatory proceedings currently pending
before the FCC which are of particular importance to the cellular industry. In
one proceeding, the FCC has imposed new "enhanced 911" regulations on cellular
carriers. Enhanced 911 capabilities would enable cellular systems to determine
the precise location of persons making emergency calls. The new rules will
require cellular carriers to work with local public safety officials to process
911 calls, including those made from mobile telephones not registered with the
cellular system, will require carriers by April 1998 to be able to identify the
cell from which the call has been made, and will require cellular systems to
improve their ability to locate wireless 911 callers over a five-year period.
 
    The FCC has adopted a limited expansion of the obligation of cellular
carriers to serve the roaming subscribers of broadband PCS providers, among
others, even though the subscribers involved have no pre-existing service
relationship with that carrier. Under these new policies, broadband PCS
providers may offer their subscribers handsets which are capable of operating
over broadband PCS and cellular networks so that when their subscribers are out
of range of broadband PCS networks, they will be able to obtain non-automatic
access to cellular networks. The FCC expects that implementation of these
roaming capabilities will promote competition between broadband PCS and cellular
service providers.
 
    The FCC has adopted requirements which will make it possible for subscribers
to retain, at the same location, their existing telephone numbers when they
switch from one service provider to another. This numbering portability will
include switching between Local Exchange Carriers ("LECs") and other wireline
providers, between wireless service providers and between LEC/wireline and
wireless providers. LECs have implementation deadlines by the end of 1998.
Broadband PCS, cellular and certain other wireless providers have phased
implementation deadlines in 1998 and 1999.
 
    In another proceeding, the FCC in 1996 adopted rules regarding the method by
which cellular carriers and LECs shall compensate each other for interconnecting
cellular and local exchange facilities. The FCC rules provided for symmetrical
and reciprocal compensation between LECs and cellular carriers, and also
prescribed interim interconnection proxy rates, which are much lower than the
rates formerly paid by cellular carriers to LECs. Symmetrical and reciprocal
compensation means they must pay each other at the same rate. The U.S. Court of
Appeals for the Eighth Circuit has vacated the FCC's rules. However, the FCC's
rules requiring reciprocal and symmetrical compensation remain in effect as
applied to the cellular industry. Interconnection rate issues will be decided by
the states. Whether the issue is decided by the states or the federal
government, cellular carriers in the future can be expected to pay lower rates
to LECs than they previously paid. This result is expected to be favorable to
the wireless industry and somewhat unfavorable to LECs.
 
    The FCC is also proceeding to implement other parts of the 1996 Act. The
1996 Act provides that implementing its legislative objectives will be the task
of the FCC, the state public utilities commissions and a Federal-state Joint
Board. Much of this implementation is proceeding in numerous, concurrent
proceedings with aggressive deadlines. The Company cannot predict the full
extent of, nature of and interrelationships among state and federal
implementation and other responses to the 1996 Act.
 
    The primary purpose and effect of the new law is to open all
telecommunications markets to competition. The 1996 Act makes most direct or
indirect state and local barriers to competition unlawful. It directs the FCC to
preempt all inconsistent state and local laws and regulations, after notice and
comment proceedings. It also enables electric and other utilities to engage in
telecommunications service through qualifying subsidiaries.
 
    Only narrow powers over competitive entry are left to state and local
authorities. Each state retains the power to impose competitively neutral
requirements that are consistent with the 1996 Act's universal
 
20
<PAGE>
service provision and necessary for universal services, public safety and
welfare, continued service quality and consumer rights. While a state may not
impose requirements that effectively function as barriers to entry, it retains
limited authority to regulate certain competitive practices in rural telephone
company service areas.
 
    The 1996 Act establishes principles and a process for implementing a
modified "universal service" policy. This policy seeks nationwide, affordable
service and access to advanced telecommunications and information services. It
calls for reasonably comparable urban and rural rates and services. The 1996 Act
also requires universal service to schools, libraries and rural health
facilities at discounted rates. The FCC has implemented the mandate of the 1996
Act to create a new universal service support mechanism "to ensure that all
Americans have access to telecommunications services." The 1996 Act requires all
interstate telecommunications providers, including wireless service providers,
to "make an equitable and non-discriminatory contribution," to support the cost
of providing universal service, unless their contribution would be de minimis.
At present, the provision of landline telephone service in high-cost areas is
subsidized by access charges and other payments by interexchange carriers to
LECs. The obligation to make payments to support universal service has been
expanded to include other telecommunications service providers, including
cellular carriers. Such payments, which are to be based on a percentage of the
total "billed revenue" of carriers for a given previous half year, began in the
first quarter of 1998. Carriers are free to pass such charges on to their
customers. Cellular carriers are also eligible to receive universal service
support payments in certain circumstances under the new systems if they provide
specified services in "high-cost" areas. The Company has sought designation as
an "eligible telecommunications carrier" qualified to receive universal service
support in certain states.
 
    Under a 1994 federal law, the Communications Assistance to Law Enforcement
Act, all telecommunications carriers, including the Company and other wireless
licensees, must, by October 1998, implement certain equipment changes necessary
to assist law enforcement authorities in achieving an enhanced ability to
conduct electronic surveillance of those suspected of criminal activity.
However, owing to disputes between the Federal Bureau of Investigation and the
relevant industry groups about the law's requirements, the FCC has not yet
adopted the necessary technical standards to enable carriers to meet those
requirements. Questions also exist regarding reimbursement by a federal fund of
certain of the costs involved. The Company has supported the efforts of industry
groups to obtain from the FCC a postponement of the October 1998 deadline on the
grounds that compliance with the originally proposed schedule is impossible. The
FCC is considering these requests for postponement, and legislation mandating a
two-year postponement is also pending in Congress.
 
    The FCC has also allocated a total of 140 megahertz ("MHz") to broadband
PCS, 20 MHz to unlicensed operations and 120 MHz to licensed operations,
consisting of two 30 MHz blocks in each of the 51 Major Trading Areas ("MTAs")
and one 30 MHz block and three 10 MHz blocks in each of 493 Basic Trading Areas
("BTAs"). Cellular operators and those entities under common ownership with them
are permitted to participate in the ownership of PCS licenses, except for those
PCS licenses reserved for small businesses, and licenses for PCS service areas
in which the cellular operator owns a 20% or greater interest in a cellular
licensee, the service area of which covers 10% or more of the population of the
PCS service area. In the latter case, the cellular license is limited to two 10
MHz PCS channel blocks.
 
    PCS technology is currently under development and is similar in some
respects to cellular technology. Where it has become commercially available,
this technology is capable of offering increased capacity for wireless two-way
and one-way voice, data and multimedia communications services and will result
in increased competition with the Company's operations. The ability of these
future PCS licensees to complement or compete with existing cellular licensees
will be affected by future FCC rule-makings. These and other future
technological and regulatory developments in the wireless telecommunications
industry and the enhancement of current technologies will likely create new
products and services that are competitive with the services currently offered
by the Company. There can be no assurance that the Company will not be adversely
affected by such technological and regulatory developments.
 
    Media reports have suggested that certain radio frequency ("RF") emissions
from portable cellular telephones might be linked to cancer. The Company has
reviewed relevant scientific information and, based on such information, is not
aware of any credible evidence linking the usage of portable cellular telephones
with cancer.
 
                                                                              21
<PAGE>
    STATE AND LOCAL REGULATION.  The Company is also subject to state and local
regulation in some instances. In 1981, the FCC preempted the states from
exercising jurisdiction in the areas of licensing, technical standards and
market structure. In 1993, Congress preempted states from regulating the entry
of cellular systems into service and the rates charged by cellular systems to
customers. The siting and construction of the cellular facilities, including
transmitter towers, antennas and equipment shelters are still subject to state
or local zoning and land use regulations. However, in 1996, Congress amended the
Communications Act to provide that states could not discriminate against
wireless carriers in tower zoning proceedings and had to decide on zoning
requests with reasonable speed. In addition, states may still regulate other
terms and conditions of cellular service. The FCC is currently considering
whether to take action to preempt moratoria imposed by certain localities on the
construction of wireless towers. The Company has supported such FCC action.
 
    The FCC is required to forbear from applying any statutory or regulatory
provision that is not necessary to keep telecommunications rates and terms
reasonable or to protect consumers. A state may not apply a statutory or
regulatory provision that the FCC decides to forbear from applying. In addition,
the FCC must review its telecommunications regulations every two years and
change any that are no longer necessary. Further, the FCC is empowered under
certain circumstances to preempt state regulatory authorities if a state is
obstructing the Communications Act's basic purposes.
 
    The Company and its subsidiaries have been and intend to remain active
participants in proceedings before the FCC and, through its membership in state
associations of wireless providers, before state regulatory authorities.
Proceedings with respect to the foregoing policy issues before the FCC and state
regulatory authorities could have a significant impact on the competitive market
structure among wireless providers and the relationships between wireless
providers and other carriers. The Company is unable to predict the scope, pace
or financial impact of policy changes which could be adopted in these
proceedings.
 
COMPETITION
 
    The Company's principal competitor for cellular telephone service in each
market is the licensee of the second cellular system in that market. Since each
competitor operates its cellular system on a 25 MHz frequency block licensed by
the FCC using comparable technology and facilities, competition for customers
between the two systems in each market is principally on the basis of quality of
service, price, size of area covered, services offered, and responsiveness of
customer service. The competing entities in many of the markets in which the
Company has an interest have financial resources which are substantially greater
than those of the Company and its partners in such markets.
 
    The FCC's rules require all operational cellular systems to provide, on a
nondiscriminatory basis, cellular service to resellers which purchase blocks of
mobile telephone numbers from an operational system and then resell them to the
public.
 
    In addition to competition from the other cellular licensee in each market,
there is also competition from, among other technologies, SMR systems, which are
able to connect with the landline telephone network. The Company believes that
conventional SMR systems are competitively disadvantaged because of
technological limitations on the capacity of such systems. The FCC has recently
given approval, through waivers of its rules, to ESMR, an enhanced SMR system.
ESMR systems may have cells and frequency reuse like cellular, thereby
potentially eliminating any current technological limitation. The first ESMR
systems were implemented in 1993 in Los Angeles and are beginning to be
constructed in several other cities across the United States. In 1995, an ESMR
provider initiated service in Tulsa, Oklahoma, where the Company operates a
cellular system. ESMR service is also being provided in certain other of the
Company's markets. Although less directly a substitute for cellular service,
wireless data services and one-way paging service (and in the future, two-way
paging services) may be adequate for those who do not need full two-way voice
service.
 
    PCS providers have initiated service in many markets across the United
States, including markets where the Company has operations. PCS providers offer
digital, wireless communications services to their customers. Similar
technological advances or regulatory changes in the future may make available
other alternatives to cellular service, thereby creating additional sources of
competition. The Company expects PCS operators to complete initial deployment of
PCS in portions of all of the Company's clusters by the end of 1998.
 
22
<PAGE>
    Continuing technological advances in the communications field make it
difficult to predict the extent of additional future competition for cellular
systems. For example, the FCC has allocated radio channels to a mobile satellite
system in which transmissions from mobile units to satellites would augment or
replace transmissions to cell sites, and several consortia to provide such
service have been formed. Such a system is designed primarily to serve the
communications needs of remote locations and a mobile satellite system could
provide viable competition for land-based cellular systems in such areas. It is
also possible that the FCC may in the future assign additional frequencies to
cellular telephone service to provide for more than two cellular telephone
systems per market.
 
EMPLOYEES
 
    The Company had 4,600 employees as of December 31, 1997. None of the
Company's employees is represented by a labor organization. The Company
considers its relationship with its employees to be good.
 
- --------------------------------------------------------------------------------
 
ITEM 2.  PROPERTIES
 
    The property for mobile telephone switching offices and cell sites are
either owned or leased under long-term leases by the Company, one of its
subsidiaries or the partnership or corporation which holds the license. The
Company has not experienced major problems with obtaining zoning approval for
cell sites or operating facilities and does not anticipate any such problems in
the future which are or will be material to the Company and its subsidiaries as
a whole. The Company's investment in property is small compared to its
investment in licenses and cellular system equipment.
 
    The Company leases approximately 95,000 square feet of office space for its
headquarters in Chicago, Illinois.
 
    The Company considers the properties owned or leased by it and its
subsidiaries to be suitable and adequate for their respective business
operations.
 
- --------------------------------------------------------------------------------
 
ITEM 3.  LEGAL PROCEEDINGS
 
    In addition to the legal proceedings discussed previously in "Proposed TDS
Corporate Restructuring," the Company is involved in legal proceedings related
to its business from time to time. The Company does not believe that any such
proceeding should have a material adverse impact on the Company.

                       SUMMARY OF 1997 BONUS PROGRAM FOR
                           SENIOR CORPORATE STAFF OF
                      UNITED STATES CELLULAR CORPORATION


     The objectives of the 1997 Bonus Program for Senior Corporate Staff (the 
"1997 Bonus Plan") of United States Cellular Corporation ("USM") are: (i) to 
provide suitable incentives for the senior corporate management of USM to 
extend their best efforts to achieve superior results in relation to key 
performance targets, (ii) to suitably reward USM's senior corporate 
management team in relation to their success in meeting and exceeding these 
performance targets, and (iii) to help USM attract and retain talented 
management personnel in positions of critical importance to the success of 
USM.  A team performance award and an individual performance award are 
available under the 1997 Bonus Plan.

     For target performance on the team and individual categories, the 1997 
Bonus Plan was designed to generate a targeted 1997 bonus pool equal to the 
total of 35% of the aggregate of the base salaries of the Company's senior 
executive officers other than the President.  Under the 1997 Bonus Plan, the 
size of the target bonus pool is increased or decreased depending on USM's 
1997 achievements with respect to the performance categories.  No bonus pool 
is paid under such plan if minimum performance levels are not achieved in 
these categories.  The maximum bonus pool that could be generated, which 
would require exceptional performance in all areas, would equal the total of 
70% of the aggregate base salaries of the Company's executive officers other 
than the President.  At target performance, the bonus pool would be equal to 
35% of the aggregate salaries of the Company's executive officers other than 
the President.  Of this percentage, 7% represents a targeted individual 
performance award and a total of 28% represents a targeted team bonus award.  
The targeted team award includes a discretionary team award of 4.2% and an 
objective award of 23.8% for a total targeted team bonus award of 28%.  The 
objective performance categories include (i) penetration (5.6% of the 
targeted award) (ii) cash flow (8.4% of the targeted award), (iii) service 
revenue (5.6% of the targeted award) and (iv) quality improvement (4.2% of 
the targeted award).

RESULTS OF OPERATIONS
 
    United States Cellular Corporation (the "Company"--AMEX symbol: USM) owns,
operates and invests in cellular markets throughout the United States. USM is an
81.1%-owned subsidiary of Telephone and Data Systems, Inc. ("TDS"). See
"Proposed TDS Corporate Restructuring" for further information on TDS's
ownership of USM.
 
    USM owned either majority or minority cellular interests in 192 markets at
December 31, 1997, representing 26,179,000 population equivalents ("pops"). USM
included the operations of 134 majority-owned and managed cellular markets,
representing 22.6 million pops, in consolidated operations ("consolidated
markets") as of December 31, 1997. Minority interests in 51 markets,
representing 3.5 million pops, were accounted for using the equity method and
were included in investment income at that date. All other interests,
representing less than 100,000 pops in the aggregate, were accounted for using
the cost method. Following is a table of summarized operating data for USM's
consolidated operations.

(1) Calculated using the respective Donnelley Marketing Service estimates for
    each year (Claritas for 1997).
 
(2) Recomputed to show the effect of change in current year presentation of
    certain revenues and expenses.
 
    The Company's operating income for 1997 and 1996, which includes 100% of the
revenues and expenses of its consolidated markets plus its corporate office
operations, primarily reflects improvement in the Company's overall operations
compared to 1996 and 1995. The improvements resulted from growth in the
Company's customer base and revenues in each year, coupled with increasing
economies of scale in both years. Operating revenues, driven by increases in
customers served, rose $196.9 million, or 29%, in 1997 and $199.8 million, or
42%, in 1996. Operating expenses rose $154.7 million, or 26%, in 1997 and $155.1
million, or 35%, in 1996. Operating cash flow (operating income before minority
share plus depreciation and amortization expense) increased $65.7 million, or
33%, in 1997 and $64.0 million, or 48%, in 1996.
 
    Beginning on January 1, 1997, the Company changed its income statement
presentation of certain credits given to customers on their monthly bills.
Customer incentive programs which result in either new or current customers
receiving free or reduced-price airtime or access are now reported as a
reduction of local retail revenue. Prior to January 1, 1997, the Company
reported the foregone revenues resulting from these incentive programs as
marketing and selling expense (for new customers) and general and administrative
expense (for current customers). Amounts in the currently affected revenue and
expense categories have been reclassified for previous years, including the 1996
and 1995 information provided throughout this Annual Report. Operating income
and net income are not affected by this change.

    Investment and other income decreased $83.5 million, or 44%, to $107.6
million in 1997, due primarily to the decrease of $102.4 million in gains on the
sales of cellular interests. Investment and other income increased $66.4
million, or 53%, in 1996, due primarily to the increase of $49.2 million in
gains on the sales of cellular and other investments. Interest expense increased
$6.3 million, or 27%, in 1997 and decreased $4.2 million, or 15%, in 1996.
Income tax expense decreased $27.7 million to $83.9 million in 1997, as improved
operating results were more than offset by decreased gains on the sales of
cellular and other investments. Income tax expense increased $79.1 million in
1996, primarily due to the increase in gains on the sales of cellular and other
investments.
 
    Net income totaled $111.5 million in 1997, a decrease of $18.4 million, or
14%, from 1996, and totaled $129.9 million in 1996, an increase of $30.2
million, or 30%, over 1995. In all three years, net income included gains on
sales of cellular and other investments. A summary of the after-tax effects of
these gains on net income and earnings per share-diluted is shown on the next
page.

OPERATING REVENUES
 
    OPERATING REVENUES totaled $877.0 million in 1997, up $196.9 million, or
29%, over 1996. Operating revenues totaled $680.1 million in 1996, up $199.8
million, or 42%, over 1995. As explained previously, operating revenues for 1996
and 1995 have been reclassified to conform to current period presentation of
customer incentive program credits.
 
    SERVICE REVENUES primarily consist of: (i) charges for access, airtime and
value-added services provided to the Company's local retail customers who use
the local systems operated by the Company ("local retail"); (ii) charges to
customers of other systems who use the Company's cellular systems when roaming
("inbound roaming"); and (iii) charges for long-distance calls made on the
Company's systems. Service revenues totaled $853.0 million in 1997, up $190.3
million, or 29%, over 1996. Service revenues totaled $662.7 million in 1996, up
$198.1 million, or 43%, over 1995. The increases in both years were primarily
due to the growing number of local retail customers and the growth in inbound
roaming revenue. The reclassification of customer bill credits reduced service
revenues from what would have been reported by $49.0 million, or 5%, in 1997,
and from what was reported by $27.8 million, or 4%, in 1996 and $12.1 million,
or 3%, in 1995.
 
    Average monthly service revenue per customer totaled $54.18 in 1997, $63.69
in 1996 and $70.64 in 1995, representing declines of 15% in 1997 and 10% in
1996. The decrease in average monthly service revenue per customer in both years
resulted from a decrease in average revenue per minute of use from both local
retail customers and inbound roamers. Also contributing was slower growth in
inbound roaming minutes of use when compared to the growth in the Company's
customer base. The reclassification of customer bill credits reduced average
monthly service revenue per customer from what would have been reported by
$3.11, or 5%, in 1997, and from what was reported by $2.67, or 4%, in 1996 and
$1.84, or 3%, in 1995.
 
                                       2
<PAGE>
    Competitive pressures and the Company's increasing use of pricing and other
incentive programs that encourage weekend and off-peak usage at reduced rates,
in order to stimulate overall usage, plus increasing amounts of bill credits
given to new and current customers as incentives to become or remain the
Company's customers, resulted in decreases in average local retail revenue per
minute of use during both 1997 and 1996. The Company's average inbound roaming
revenue per minute of use also decreased during both 1997 and 1996, in line with
the ongoing trend toward reduced per minute prices for roaming negotiated
between the Company and other cellular operators. Also, the Company believes
that its customer base is growing faster than that of the cellular industry as a
whole, which has a dilutive effect on inbound roaming revenue per customer.
Inbound roaming minutes of use have been growing at a slower rate than the
Company's customer base (27% and 38% growth in inbound roaming minutes in 1997
and 1996, respectively, compared to 59% and 51% growth in the Company's customer
base).
 
    LOCAL RETAIL REVENUE increased $153.8 million, or 37%, in 1997 and $137.4
million, or 50%, in 1996. Growth in the Company's customer base was the primary
reason for the increases in local retail revenue in both years. The number of
customers increased 59% to 1,710,000 at December 31, 1997, and increased 51% to
1,073,000 at December 31, 1996. The Company added 442,000 net new customers from
its marketing channels in 1997 compared to 365,000 in 1996. Management
anticipates that the growth rate in the Company's customer base will be lower in
the future, primarily as a result of an increase in the number of competitors in
its markets. The reclassification of customer bill credits reduced local retail
revenue from what would have been reported by $49.0 million, or 8%, in 1997, and
from what was reported by $27.8 million, or 6%, in 1996 and $12.1 million, or
4%, in 1995.
 
    Average monthly local retail revenue per customer declined to $36.11 in 1997
from $39.87 in 1996 and $42.19 in 1995. Monthly local retail minutes of use per
customer decreased 4% to 103 in 1997, and increased 13% to 107 in 1996. Average
revenue per minute of use decreased in both years as a result of the pricing and
other incentive programs stated previously. Average local retail revenue per
minute totaled $.35 in 1997 compared to $.37 in 1996 and $.44 in 1995. The
decrease in average monthly local retail revenue per customer is part of an
industry-wide trend and is believed to be related to the tendency of the early
customers in a market to be the heaviest users during peak business hours. It
also reflects the increasing level of competition for wireless services and the
Company's and the industry's continued penetration of the consumer market, which
tends to include fewer peak business hour-usage customers. The reclassification
of customer bill credits reduced average monthly local retail revenue per
customer from what would have been reported by $3.11, or 8%, in 1997, and from
what was reported by $2.67, or 6%, in 1996 and $1.84, or 4%, in 1995.
 
    INBOUND ROAMING REVENUE increased $24.2 million, or 13%, in 1997 and $45.3
million, or 31%, in 1996. Both the 1997 and 1996 increases were attributable to
the respective 27% and 38% increases in the number of minutes used by customers
from other wireless systems when roaming in the Company's service areas. Also
contributing were the increased number of cell sites within the Company's
service areas. These effects were offset somewhat by the decrease in average
revenue per minute due to the downward trend in negotiated rates. Average
inbound roaming revenue per minute totaled $.83 in 1997, $.92 in 1996 and $.99
in 1995. Monthly inbound roaming revenue per Company customer averaged $13.81 in
1997, $18.58 in 1996 and $22.51 in 1995. The decreases in monthly inbound
roaming revenue per Company customer are related to both the decreases in
inbound roaming revenue per minute and the faster increases in the Company's
customer base as compared to the growth in inbound roaming minutes of use.
 
    LONG-DISTANCE REVENUE increased $12.0 million, or 23%, in 1997 and $17.3
million, or 49%, in 1996 as the volume of long-distance calls billed by the
Company increased. Monthly long-distance revenue per customer averaged $4.10 in
1997, $5.05 in 1996 and $5.36 in 1995. The decrease in monthly long-distance
revenue per customer is primarily due to the dilution of the portion of
long-distance revenue that comes from inbound roaming customers. In a manner
similar to inbound roaming revenue, this revenue is not growing as fast as the
Company's customer base.
 
                                       3
<PAGE>
    EQUIPMENT SALES REVENUES increased $6.6 million, or 38%, in 1997 and $1.6
million, or 10%, in 1996. Equipment sales reflect the sale of 587,000, 449,000
and 296,000 cellular telephone units in 1997, 1996 and 1995, respectively, plus
installation and accessories revenue. The average revenue per unit was $41 in
1997, $39 in 1996 and $53 in 1995. The average revenue per unit in all years is
significantly less than the Company's cost per unit, which partially reflects
the Company's decision to reduce sales prices on cellular telephones to
stimulate growth in the number of customers, to maintain its market position and
to meet competitive prices as well as to pass through reduced manufacturers'
prices to customers. Also, the Company uses promotions which are based on
increased equipment discounting. The success of these promotions has led to both
an increase in units sold and a general decline in average equipment sales
revenue per unit over the last several years.
 
OPERATING EXPENSES
 
    OPERATING EXPENSES totaled $747.4 million in 1997, up $154.7 million, or
26%, over 1996. Operating expenses totaled $592.7 million in 1996, up $155.1
million, or 35%, over 1995. As explained previously, operating expenses for 1996
and 1995 have been reclassified to conform to current period presentation of
customer incentive program credits. The reclassification of customer bill
credits reduced operating expenses from what would have been reported by $49.0
million, or 6%, in 1997, and from what was reported by $27.8 million, or 4%, in
1996 and $12.1 million, or 3%, in 1995.
 
    SYSTEM OPERATIONS EXPENSES increased $35.8 million, or 30%, in 1997 and
$46.9 million, or 67%, in 1996. These increases were primarily due to increases
in customer usage expenses and costs associated with serving the Company's
increased number of customers, which include the costs of roaming fraud, and the
growing number of cell sites within the Company's systems. In 1997, the Company
significantly reduced its expenses related to roaming fraud, resulting in a
decline in the percentage increase in total system operations expenses during
the year. In total, system operations costs are expected to continue to increase
as the number of customers using and the number of cell sites within the
Company's systems grows.
 
    Customer usage expenses represent charges from other telecommunications
service providers for the Company's customers' use of their facilities as well
as for the Company's inbound roaming traffic on these facilities. Also included
are costs related to local interconnection to the landline network, toll charges
and expenses incurred by the Company when its customers use systems other than
their local systems ("outbound roaming"). These expenses are offset somewhat by
amounts the Company bills to its customers for outbound roaming.
 
    Customer usage expenses increased $24.3 million, or 32%, in 1997 and $40.4
million, or 116%, in 1996. The increase in 1997 is primarily due to the increase
in net outbound roaming expense, which has resulted from the Company offering
its customers increasingly larger service footprints in which their calls are
billed at local rates. In certain cases these service areas include other
operators' service areas. The Company pays roaming rates to the other carriers
for calls the Company's customers make in these areas, while charging those
customers a local rate which is usually lower than the roaming rate. Also
contributing to the increase in 1997 were costs related to the increase in
minutes used on the Company's systems, partially offset by the reduction in
costs related to fraudulent use of the Company's customers' cellular telephone
numbers. The increase in 1996 is due to both an increase in net outbound roaming
expense and an increase in fraud-related costs. These fraud-related costs
totaled $6.5 million in 1997, $18.0 million in 1996 and $4.1 million in 1995.
The Company continues to implement procedures in its markets to combat this
fraud, which is primarily related to roaming usage. Customer usage expenses
represented 12% of service revenues in 1997, 11% in 1996 and 7% in 1995.
 
    Maintenance, utility and cell site expenses increased $11.5 million, or 27%,
in 1997, and $6.5 million, or 18%, in 1996. The increases primarily reflect an
increase in the number of cell sites in the Company's systems each year, to
1,748 in 1997 from 1,328 in 1996 and 1,116 in 1995. Monthly maintenance, utility
and
 
                                       4
<PAGE>
cell site expenses totaled $2,900, $2,866 and $3,107 per average cell site in
1997, 1996 and 1995, respectively.
 
    MARKETING AND SELLING EXPENSES increased $47.4 million, or 37%, in 1997 and
$35.5 million, or 39%, in 1996. Marketing and selling expenses primarily consist
of salaries, commissions and expenses of field sales and retail personnel and
offices; agent expenses; local advertising and public relations expenses. The
1997 increase was primarily due to a 33% rise in the number of gross customer
activations (excluding acquisitions and divestitures), to 746,000 in 1997 from
563,000 in 1996. Also in 1997, the Company increased its advertising expenses,
particularly brand advertising, to promote the United States Cellular-Registered
Trademark-brand. The 1996 increase was primarily due to a 44% rise in the number
of gross customer activations (excluding acquisitions and divestitures), to
563,000 in 1996 from 392,000 in 1995. Cost per gross customer activation,
including losses on equipment sales, decreased to $313 in 1997 from $327 in 1996
and $335 in 1995. While cost per gross customer activation in total decreased in
1997 and 1996, the percentage of cost per gross customer activation attributable
to marketing and selling expenses increased to 75% in 1997 from 69% in 1996 and
70% in 1995. The percentage increase from 1996 to 1997 is primarily due to the
additional advertising expenses coupled with decreased losses on equipment sales
due to lower per unit manufacturer equipment prices. The reclassification of
customer bill credits reduced cost per gross addition from what would have been
reported by $52, or 14%, in 1997, and from what was reported by $40, or 11%, in
1996 and $26, or 7%, in 1995; in total, the reclassification reduced marketing
and selling expenses from what would have been reported by $38.6 million, or
18%, in 1997, and from what was reported by $22.3 million, or 15%, in 1996 and
$10.2 million, or 10%, in 1995.
 
    COST OF EQUIPMENT SOLD increased $8.3 million, or 11%, in 1997 and $19.1
million, or 35%, in 1996. The increase reflects the growth in unit sales related
to the rise in gross customer activations made through the Company's direct and
retail distribution channels, offset somewhat by falling manufacturer prices per
unit. The average cost to the Company of a telephone unit sold, including
accessories and installation, was $140 in 1997, $165 in 1996 and $186 in 1995.
 
    GENERAL AND ADMINISTRATIVE EXPENSES increased $39.7 million, or 24%, in 1997
and $34.2 million, or 26%, in 1996. These expenses include the costs of
operating the Company's local business offices and its corporate expenses. The
increases in both years include the effects of increases in expenses required to
serve the growing customer base in existing markets and an expansion of both
local administrative office and corporate staff, necessitated by growth in the
Company's business. Employee-related expenses increased $19.4 million, or 26%,
in 1997 and $15.6 million, or 27%, in 1996, primarily due to increases in the
number of administrative employees in each year. Also, bad debt expense
increased $8.0 million, or 46%, in 1997 and $5.0 million, or 40%, in 1996,
primarily due to the Company's increased penetration of the consumer market. The
Company is using an ongoing clustering strategy to combine local and customer
service operations wherever feasible in order to gain operational efficiencies
and reduce its per unit administrative expenses. Monthly general and
administrative expenses per customer decreased to $12.99 in 1997 from $15.84 in
1996 and $19.85 in 1995. The reclassification of customer bill credits reduced
general and administrative expenses from what would have been reported by $10.4
million, or 5%, in 1997, and from what was reported by $5.5 million, or 3%, in
1996 and $1.9 million, or 1%, in 1995.
 
    Operating cash flow increased $65.7 million, or 33%, to $261.9 million in
1997 and increased $64.0 million, or 48%, to $196.2 million in 1996. The
improvements in both years were primarily due to substantial growth in customers
and service revenues and the effects of improved operational efficiencies on
cash operating expenses. Operating cash flow margins (as a percent of service
revenues) were 30.7% in 1997, 29.6% in 1996 and 28.5% in 1995; had the
reclassification of customer bill credits not been made, operating cash flow
margins would have been 29.0% in 1997, 28.4% in 1996 and 27.7% in 1995.
 
    DEPRECIATION EXPENSE increased $23.0 million, or 31%, in 1997 and $17.3
million, or 30%, in 1996. The increase reflects rising average fixed asset
balances, which increased 35% in 1997 and 34% in 1996.
 
                                       5
<PAGE>
Increased fixed asset balances primarily result from the increase in cell sites
built to improve coverage and capacity in the Company's markets.
 
OPERATING INCOME BEFORE MINORITY SHARE
 
    OPERATING INCOME BEFORE MINORITY SHARE totaled $129.5 million in 1997, $87.4
million in 1996 and $42.8 million in 1995. The operating income margin was 15.2%
in 1997, 13.2% in 1996 and 9.2% in 1995; had the reclassification of customer
bill credits not been made, operating income margins would have been 14.4% in
1997, 12.7% in 1996 and 9.0% in 1995. The improvement in operating income and
operating income margin reflects increased revenues resulting from growth in the
number of customers served by the Company's systems and the effect of improved
operational efficiencies on total operating expenses.
 
    The Company expects service revenues to continue to grow during 1998;
however, management anticipates that average monthly revenue per customer will
continue to decrease as local retail and inbound roaming revenue per minute of
use decline and as the Company further penetrates the consumer market.
Additionally, the Company expects expenses to increase during 1998 as it incurs
costs associated with both customer growth and cell sites added.
 
    Management believes there exists a seasonality in both service revenues,
which tend to increase more slowly in the first and fourth quarters, and
operating expenses, which tend to be higher in the fourth quarter due to
increased marketing activities and customer growth, which may cause operating
income to vary from quarter to quarter. Additionally, competitors licensed to
provide personal communications services ("PCS") have initiated service in
certain of the Company's markets over the past eighteen months. The Company
expects PCS operators to complete initial deployment of PCS in portions of all
of the Company's clusters by the end of 1998. The Company has increased its
advertising, particularly brand advertising, in 1997 to promote the United
States Cellular-Registered Trademark- brand and distinguish the Company's
service from other wireless communications providers. The Company's management
continues to monitor other wireless communications providers' strategies to
determine what effects additional competition will have on the Company's future
strategies and results. While the effects of additional wireless competition
have slowed customer growth in certain of the Company's markets, the overall
effect on the Company's total customer growth to date has not been material.
 
INVESTMENT AND OTHER INCOME
 
    INVESTMENT AND OTHER INCOME totaled $107.6 million in 1997, $191.1 million
in 1996 and $124.7 million in 1995. Gain on sale of cellular and other
investments totaled $30.3 million in 1997, reflecting gains recorded on the
sales of the Company's majority interest in one market and minority interests in
two other markets, and on cash received from the settlement of a legal matter.
Gain on sale of cellular and other investments totaled $132.7 million in 1996,
reflecting gains recorded on the sales of the Company's majority interests in
eight markets and minority interests in two other markets, on cash received in
an exchange of markets with another cellular operator and on cash received from
the settlement of two separate legal matters. Gain on sale of cellular and other
investments totaled $83.5 million in 1995, reflecting gains recorded on the
sales of majority interests in six markets and minority interests in six
markets, on cash received in an exchange of markets with another cellular
operator and on the sale of certain marketable equity securities.
 
    INVESTMENT INCOME was $77.1 million in 1997 compared to $51.5 million in
1996 and $39.8 million in 1995. Investment income primarily represents the
Company's share of net income from the markets managed by others that are
accounted for by the equity method. Although investment income increased
significantly in 1996 and 1997, future investment income will be negatively
impacted by the completion of the exchange transaction with BellSouth
Corporation ("BellSouth") and the divestitures of certain minority interests to
AirTouch Communications ("AirTouch"). See "Financial Resources and Liquidity--
Acquisitions, Divestitures and Exchanges" for further discussions of these
transactions.

INTEREST AND INCOME TAXES
 
    INTEREST EXPENSE totaled $29.4 million in 1997 compared to $23.1 million in
1996 and $27.3 million in 1995. Interest expense in 1997 is primarily related to
Liquid Yield Option Notes ("LYONs") ($15.2 million); the Company's 7.25% notes
(the "Notes") issued during the third quarter of 1997 ($6.3 million); borrowings
under vendor financing agreements ($4.5 million); and borrowings under the
Revolving Credit Agreement with TDS ($1.9 million). Interest expense in 1996 is
primarily related to LYONs ($14.4 million) and borrowings under vendor financing
agreements ($8.0 million). Interest expense in 1995 is primarily related to
borrowings under the Revolving Credit Agreement with TDS ($10.4 million),
borrowings under vendor financing agreements ($9.2 million) and LYONs ($7.4
million).
 
    In August 1997, the Company sold $250 million principal amount of 7.25%
Notes under a shelf registration statement, priced to yield 7.33% to maturity.
The Notes are unsecured and become due on August 15, 2007. Interest on the Notes
is payable semi-annually on February 15 and August 15 of each year, commencing
February 15, 1998. The Notes will be redeemable, in whole or in part, at the
option of the Company at any time on or after August 15, 2004.
 
    The LYONs are zero coupon convertible debentures which accrete interest at
6% annually, but do not require current cash payments of interest. All accreted
interest is added to the outstanding principal balance on June 15 and December
15 of each year.
 
    All borrowings under the vendor financing agreements were repaid in August
1997 with a portion of the proceeds from the Notes offering. Borrowings under
the Revolving Credit Agreement with TDS were outstanding from April 1997 through
August 1997, at which time all outstanding amounts were repaid with a portion of
the proceeds from the Notes offering. Borrowings under the Revolving Credit
Agreement with TDS were also outstanding from January 1995 through June 1995, at
which time all outstanding amounts were repaid with a portion of the proceeds
from the LYONs offering.
 
    INCOME TAX EXPENSE was $83.9 million in 1997, $111.6 million in 1996 and
$32.5 million in 1995. In 1997, $14.1 million of income tax expense related to
the gains on sales of cellular and other investments compared to $65.3 million
in 1996 and $27.7 million in 1995. The effective tax rates were 43% in 1997, 46%
in 1996 and 25% in 1995. The fluctuation in each year's effective tax rate is
primarily due to the different amounts of gains on sales of cellular interests
in each year; these gains are generally taxed at a higher rate than income from
operations, due to the lower tax basis of certain interests sold which were
originally acquired in tax-free transactions. In 1997, 1996 and 1995, state
income taxes and gains on sales of cellular and other investments increased the
effective rate above the statutory federal income tax rate. In 1995, this effect
was offset by the effect of the valuation allowance on the deferred tax asset,
which decreased the effective rate below the statutory rate.
 
    TDS and the Company are parties to a Tax Allocation Agreement, pursuant to
which the Company is included in a consolidated federal income tax return with
other members of the TDS consolidated group. For financial reporting purposes,
the Company computes federal income taxes as if it were filing a separate return
as its own affiliated group and was not included in the TDS group.
 
    Subject to the completion of the proposed TDS corporate restructuring, TDS
intends to terminate certain intercompany agreements between TDS and the
Company. See "Proposed TDS Corporate Restructuring" for further information on
these intercompany agreements.
 
NET INCOME
 
    NET INCOME totaled $111.5 million in 1997, $129.9 million in 1996 and $99.7
million in 1995. EARNINGS PER SHARE-DILUTED was $1.29 in 1997, $1.51 in 1996 and
$1.19 in 1995. Net income and earnings per share in all three years included
gains on the sales of cellular and other investments. See Page 21 for a summary
of the after-tax effects of gains on net income and earnings per share.

FINANCIAL RESOURCES AND LIQUIDITY
 
    The Company operates a capital- and marketing-intensive business. In recent
years, the Company has generated operating cash flow and received cash proceeds
from divestitures to fund most of its construction costs and substantially all
of its operating expenses. The Company anticipates further substantial increases
in cellular units in service, revenues and cell sites as it continues its growth
strategy. Operating cash flow may fluctuate from quarter to quarter depending on
the seasonality of each of these growth factors.
 
    CASH FLOWS FROM OPERATING ACTIVITIES provided $222.1 million in 1997, $137.5
million in 1996 and $115.9 million in 1995. Operating cash flow provided $261.9
million in 1997, $196.2 million in 1996 and $132.2 million in 1995. Cash flows
from other operating activities (investment and other income, interest expense,
changes in working capital and changes in other assets and liabilities) required
cash investments totaling $39.8 million in 1997, $58.7 million in 1996 and $16.3
million in 1995.
 
    CASH FLOWS FROM FINANCING ACTIVITIES provided $135.9 million in 1997,
required $11.2 million in 1996 and provided $19.3 million in 1995. In August
1997, the Notes offering provided $243.1 million in cash. A portion of the
proceeds from the Notes offering was used to repay all outstanding borrowings
under the Revolving Credit Agreement with TDS and under vendor financing
agreements, aggregating $160.5 million. Repayments of borrowings under the
vendor financing agreements earlier in 1997 totaled $13.7 million. In 1996,
issuances of USM Common Shares, primarily to TDS, provided $10.5 million while
repayments of debt under the vendor financing agreements required $21.5 million.
In 1995, the sale of LYONs provided cash totaling $221.5 million and borrowings
under the vendor financing agreements provided cash totaling $59.5 million. This
cash was used to repay amounts owed under the Revolving Credit Agreement with
TDS totaling $251.2 million and amounts owed under the vendor financing
agreements totaling $13.4 million.
 
    CASH FLOWS FROM INVESTING ACTIVITIES required $358.5 million in 1997, $150.3
million in 1996 and $102.6 million in 1995. The company received net cash
proceeds totaling $61.1 million in 1997, $213.0 million in 1996 and $151.1
million in 1995 related to the sales and exchanges of cellular interests. Cash
distributions from cellular entities in which the Company has an interest
provided $52.4 million in 1997, $23.5 million in 1996 and $8.7 million in 1995.
Cash required for property, plant and equipment and system development
expenditures totaled $318.7 million in 1997, financed primarily with internally
generated cash and the proceeds from the Notes offering; $248.1 million in 1996,
financed primarily with internally generated funds and proceeds from the sales
of cellular interests; and $206.2 million in 1995, financed primarily with
internally generated funds and proceeds from the LYONs offering. These
expenditures primarily represent the construction of 331, 242 and 292 cell sites
in 1997, 1996 and 1995, respectively, plus other plant additions and costs
related to the development of the Company's office systems. Acquisitions
required $128.8 million in 1997, $116.4 million in 1996 and $29.3 million in
1995.
 
    Anticipated capital requirements for 1998 primarily reflect the Company's
construction and system expansion program. The Company's construction and system
expansion budget for 1998 is approximately $330 million, primarily for new cell
sites to expand and enhance the Company's coverage in its service areas and for
the enhancement of the Company's office systems.
 
ACQUISITIONS, DIVESTITURES AND EXCHANGES
 
    The Company assesses its cellular holdings on an ongoing basis in order to
maximize the benefits derived from clustering its markets. As the Company's
clusters have grown, the Company's focus has shifted toward exchanges and
divestitures of managed and investment interests. Over the past few years, the
Company has completed exchanges of controlling interests in its less strategic
markets for controlling interests in markets which better complement its
clusters. The Company has also completed outright sales of other less strategic
markets. The proceeds from these sales have been used to further the Company's
growth.

    In 1997, the Company, or TDS for the benefit of the Company, purchased
majority interests in two markets and several minority interests, representing
approximately 534,000 pops. The total consideration paid for these purchases,
primarily in the form of cash (including cash borrowed under the Revolving
Credit Agreement with TDS) and USM Common Shares issued to TDS to reimburse TDS
for the value of TDS Common Shares issued to third parties, totaled $81.4
million.
 
    Also in 1997, the Company completed an exchange with BellSouth. Pursuant to
the exchange, USM received majority interests representing approximately 4.0
million pops in exchange for majority interests representing approximately 2.0
million pops, minority interests representing approximately 1.2 million pops and
a net amount of $86.7 million in cash. The majority interests USM received are
in 12 markets adjacent to its Iowa/Missouri and Wisconsin/Illinois/Indiana
clusters.
 
    In 1996, the Company purchased majority interests in two markets and several
minority interests, representing approximately 1.0 million pops, and received a
majority interest in another market through an exchange with another cellular
operator. The total consideration paid for these purchases, primarily in the
form of cash and USM Common Shares issued to TDS to reimburse TDS for the value
of TDS Common Shares issued to third parties, totaled $158.9 million. Included
in these acquisitions are minority interests representing approximately 598,000
pops the Company acquired from TDS for $102.8 million in cash, pursuant to an
agreement entered into in June 1996.
 
    In 1995, the Company purchased majority interests in 11 markets and several
minority interests, representing approximately 1.7 million pops. The total
consideration paid for these purchases, primarily in the form of cash and USM
Common Shares issued or issuable to TDS to reimburse TDS for the value of TDS
Common Shares issued and issuable and cash paid to third parties, totaled $151.0
million. The Company also acquired majority interests in 12 markets,
representing approximately 2.0 million pops, as a result of six separate
exchange transactions completed during 1995.
 
    In 1997, the Company sold a majority interest in one market and minority
interests in two other markets, representing approximately 358,000 pops, for an
aggregate consideration of $54.5 million in cash and receivables. The two
minority interests involved interests the Company had previously acquired from
TDS pursuant to the June 1996 agreement between the two companies. In the
aggregate, the Company recorded a substantial book gain on the divestitures of
the interests acquired from TDS.
 
    In 1996, the Company sold majority interests in eight markets and minority
interests in two other markets, representing approximately 1.2 million pops, and
divested a majority interest in another market through an exchange with another
cellular operator. The Company received cash consideration totaling $187.8
million from these sales and from the exchange. The Company also settled two
separate legal matters during 1996, receiving $30.3 million in cash from those
transactions. In total, sales, exchanges and litigation settlements provided the
Company with cash totaling $218.1 million in 1996.
 
    In 1995, the Company sold majority interests in six markets and minority
interests in six markets, representing approximately 1.1 million pops. The
Company received consideration consisting of cash and receivables totaling
$128.2 million from these sales. The Company also divested majority interests in
10 markets, representing approximately 2.1 million pops, as a result of the
exchange transactions completed during 1995.
 
    At December 31, 1997, the Company had entered into agreements to acquire a
majority interest in one market and a minority interest in a market in which the
Company owns a majority interest, representing approximately 410,000 pops, for
$51.3 million in cash. If the majority interest is acquired as expected, the
Company will subsequently sell that interest to BellSouth for cash.
 
    Also at December 31, 1997, the Company had entered into agreements with
AirTouch to divest minority interests in nine markets, representing
approximately 759,000 pops. In exchange, the agreements provided that the
Company will receive approximately 4.0 million shares of AirTouch stock and cash
totaling $54.2 million. In addition, the Company will receive approximately
$27.0 million in cash from TDS
 
                                       9
<PAGE>
pursuant to a contract right termination agreement entered into between the
Company and TDS. This agreement is related to two interests which are to be sold
directly by TDS to AirTouch and which were to be acquired by the Company as part
of the June 1996 agreement between the Company and TDS. The contract right
termination agreement will enable the Company to receive cash equal to the value
of the gain the Company would have realized had it purchased the interests from
TDS and sold them to AirTouch under terms similar to those in the agreement
between TDS and AirTouch.
 
    Additionally, the Company has entered into an agreement to sell its minority
interests in two other markets, representing approximately 176,000 pops, for
$37.6 million in cash. The Company expects these pending transactions to be
completed during the first half of 1998. The Company anticipates that it will
record significant book gains on these divestitures when the transactions are
completed.
 
LIQUIDITY
 
    The Company anticipates that the aggregate resources required for 1998 will
include approximately $330 million for capital spending and approximately $51
million to complete pending acquisitions. The Company is generating substantial
cash from its operations and anticipates financing its capital spending for 1998
primarily with internally generated cash. The Company had $14 million of cash
and cash equivalents at December 31, 1997 and expects to receive approximately
$119 million from pending divestitures and the contract right termination
agreement during 1998.
 
    Additionally, in August 1997 the Company established a $500 million
revolving credit facility with a group of banks. This seven-year facility
replaces the Company's Revolving Credit Agreement with TDS as the Company's
primary short-term borrowing facility. No borrowings have been made under the
new credit facility through December 31, 1997.
 
    The Company filed a shelf registration statement in July 1997 covering $400
million of debt securities, and in August 1997 sold $250 million of Notes under
such shelf registration statement. The remaining $150 million is available for
future transactions.
 
    Management believes that the nature of the interest rate bases related to
the Company's current and potential future debt financing sources do not subject
the Company to material market risk exposures.
 
    Management believes that the Company's operating cash flows and sources of
external financing, including the above-referenced revolving credit facility and
shelf registration, provide substantial financial flexibility for the Company to
meet both its short and long-term needs. The Company also currently has access
to public and private capital markets to help meet its long-term financing
needs. The Company anticipates issuing debt and equity securities only when
capital requirements (including acquisitions), financial market conditions and
other factors warrant.
 
    The Company has assessed and continues to assess the impact of the Year 2000
on its reporting systems and operations (the "Year 2000 Issue"), and is taking
steps to make its systems Year 2000 compliant. The Year 2000 Issue exists
because many computer systems and applications abbreviate dates by eliminating
the first two digits of the year, assuming that these two digits will always be
"19." Unless corrected, this shortcut is expected to cause problems beginning on
January 1, 2000. On that date, some computer programs may recognize the date as
January 1, 1900. This may cause systems to incorrectly process critical
financial and operational information, or stop processing altogether.
Additionally, computer applications may be affected before January 1, 2000, if
calculations into the year 2000 are involved. The costs to date of addressing
the Year 2000 Issue have not been material to the Company's results of
operations or financial condition, and management believes that the costs to be
incurred in the future will not be material to future results or financial
condition. If management's steps are not successful in making the systems Year
2000 compliant, it could have a material adverse effect on results of
operations.

PROPOSED TDS CORPORATE RESTRUCTURING
 
    In December 1997, the Company received a proposal from TDS to acquire all of
the issued and outstanding Common Shares of USM not already owned by TDS. The
offer was made in connection with, and is subject to TDS shareholder approval of
and the effectiveness of, TDS's proposed corporate restructuring. The Board of
Directors of TDS (the "TDS Board") has adopted a proposal which, if approved by
TDS shareholders and implemented by the TDS Board, would authorize the TDS Board
to issue three new classes of common stock and change the state of incorporation
of TDS from Iowa to Delaware (the "Tracking Stock Proposal"). The three new
classes of stock are intended to separately reflect the performance of TDS's
cellular telephone, landline telephone and personal communications services
businesses ("Tracking Stocks").
 
    Under the Tracking Stock Proposal, one of the three new classes of common
stock created by TDS would be designated as United States Cellular Group Common
Shares (the "Cellular Group Shares"). The Cellular Group Shares, when issued,
are intended to reflect the separate performance of the United States Cellular
Group (the "Cellular Group"), which consists of TDS's interest in United States
Cellular Corporation.
 
    Subject to the approval of the Tracking Stock Proposal by TDS shareholders,
TDS intends to, among other things, issue Cellular Group Shares in exchange for
all of the Common Shares of the Company which are not currently owned by TDS,
subject to approval by the Company's board of directors and shareholders.
 
    In January 1998, the Company's Board of Directors created a special
committee of the Board (the "Special Committee") to review the proposal from
TDS. The Special Committee, consisting of one independent director of the
Company, has engaged a financial advisor and legal advisor to assist in
reviewing the proposal. The Special Committee will consider how the Company
should respond to the TDS proposal, take the steps it deems appropriate to
respond to the TDS proposal and, at such time as it considers it appropriate,
report its recommendations to the Company's Board of Directors.
 
    Subsequent to TDS shareholder approval of the Tracking Stock Proposal, TDS
intends to terminate certain inter-company agreements between TDS and the
Company. Thereafter, all of the policies between TDS and the Company would be
determined solely by methods that TDS management believes to be reasonable. Many
of such policies would continue the arrangements which presently exist between
TDS and the Company pursuant to the intercompany agreements, but TDS would have
no contractual obligation to continue such policies after the intercompany
agreements have been terminated. The TDS Board currently intends to retain
future earnings, if any, for the development of the business of the Cellular
Group and does not anticipate paying dividends on the Cellular Group Shares in
the foreseeable future.

Note: Certain 1996 amounts were reclassified for current year presentation.
 
    Net Income for 1997 and 1996 included significant gains from the sales of
cellular and other investments. The table above summarizes the effect of the
gains on Net Income and Earnings per Common and Series A Common Share-Diluted.
 
    Management believes there exists a seasonality at the Company in both
service revenues, which tend to increase more slowly in the first and fourth
quarters, and operating expenses, which tend to be higher in the fourth quarter
due to increased marketing activities and customer growth. This seasonality may
cause operating income to vary from quarter to quarter.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. PROPOSED TDS CORPORATE RESTRUCTURING
 
    In December 1997, United States Cellular Corporation (the "Company" or
"USM") received a proposal from Telephone and Data Systems, Inc. ("TDS") to
acquire all of the issued and outstanding Common Shares of USM not already owned
by TDS. The offer was made in connection with, and is subject to, TDS
shareholder approval of and the effectiveness of, TDS's proposed corporate
restructuring. The Board of Directors of TDS (the "TDS Board") has adopted a
proposal which, if approved by TDS shareholders and implemented by the TDS
Board, would authorize the TDS Board to issue three new classes of common stock
and change the state of incorporation of TDS from Iowa to Delaware (the
"Tracking Stock Proposal"). The three new classes of stock are intended to
separately reflect the performance of TDS's cellular telephone, landline
telephone and personal communications services businesses ("Tracking Stocks").
 
    Under the Tracking Stock Proposal, one of the three new classes of common
stock created by TDS would be designated as United States Cellular Group Common
Shares (the "Cellular Group Shares"). The Cellular Group Shares, when issued,
are intended to reflect the separate performance of the United States Cellular
Group (the "Cellular Group"), which consists of TDS's interest in United States
Cellular Corporation.
 
    Subject to the approval of the Tracking Stock Proposal by TDS shareholders,
TDS intends to, among other things, issue Cellular Group Shares in exchange for
all of the Common Shares of the Company which are not currently owned by TDS,
subject to approval by the Company's board of directors and shareholders (the
"Merger").
 
    In January 1998, the Company's Board of Directors created a special
committee of the Board (the "Special Committee") to review the proposal from
TDS. The Special Committee, consisting of one independent director of the
Company, has engaged a financial advisor and legal advisor to assist in
reviewing the proposal. The Special Committee will consider how the Company
should respond to the TDS proposal, take the steps it deems appropriate to
respond to the TDS proposal and, at such time as it considers it appropriate,
report its recommendations to the Company's Board of Directors.
 
    Subsequent to TDS shareholder approval of the Tracking Stock Proposal, TDS
intends to terminate certain intercompany agreements between TDS and the
Company. Thereafter, some or all of the policies between TDS and the Company
would be determined solely by methods that TDS management believes to be
reasonable. Many of such policies would continue the arrangements which
presently exist between TDS and the Company pursuant to the intercompany
agreements, but TDS would have no contractual obligation to continue such
policies after the intercompany agreements have been terminated. The TDS Board
currently intends to retain future earnings, if any, for the development of the
business of the Cellular Group and does not anticipate paying dividends on the
Cellular Group Shares in the foreseeable future.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    The Company, a Delaware corporation, is currently an 81.1%-owned subsidiary
of Telephone and Data Systems, Inc.
 
NATURE OF OPERATIONS
 
    USM owns, manages and invests in cellular systems throughout the United
States and is the nation's eighth largest cellular telephone company in terms of
population equivalents ("pops"). The Company

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
owns interests in 192 cellular markets, representing approximately 26.2 million
pops, as of December 31, 1997. USM's 134 majority-owned and managed markets,
primarily mid-sized and rural markets, covered 24 states and served 1,710,000
customers as of December 31, 1997. USM's Midwest Regional Market Cluster, which
includes markets in Iowa, Wisconsin, Illinois and Missouri, served 709,000
customers at December 31, 1997, which represents approximately 41% of USM's
total customers served as of that date.
 
PRINCIPLES OF CONSOLIDATION
 
    The consolidated financial statements include the accounts of USM, its
majority-owned subsidiaries and partnerships in which USM has a majority
partnership interest. All material intercompany accounts and transactions have
been eliminated. Investments in entities in which the Company does not have a
majority interest are generally accounted for using the equity method.
 
    The preparation of consolidated 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 reported
period. Actual results could differ from those estimates, but management
believes any differences will not be material.
 
    Certain amounts reported in prior years have been reclassified to conform to
current period presentation.
 
CASH AND CASH EQUIVALENTS AND TEMPORARY INVESTMENTS
 
    Cash and cash equivalents include cash and those short-term, highly-liquid
investments with original maturities of three months or less. Those investments
with original maturities of more than three months to 12 months are classified
as temporary investments. Temporary investments are stated at cost. Those
investments with original maturities of more than 12 months are classified as
marketable securities and are stated at amortized cost.
 
    The carrying amounts of Cash and Cash Equivalents and Temporary Investments
approximate their fair value due to the short-term nature of these investments.
 
ACCOUNTS RECEIVABLE
 
    Accounts receivable consists of amounts owed by customers for both service
provided and equipment sales, by other cellular carriers whose customers have
used USM's cellular systems, by affiliated entities and by other partners for
capital contributions and distributions.
 
NOTES AND INTEREST RECEIVABLE
 
    Notes and interest receivable primarily consist of loans to other partners
for capital calls paid on their behalf. The interest charged on these loans is
at varying annual rates. USM also has an outstanding loan to the operators of
another cellular company in which USM has no equity. The interest charged on
this loan is at an annual rate of prime plus 1 1/2%. The carrying amount
reported in the balance sheet for notes and interest receivable approximates
their fair value.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
DEFERRED CHARGES
 
    Deferred system development costs represent costs incurred for the
development of new information systems. Capitalized costs of information systems
development are amortized over a five-year period, starting when each new system
is placed in service.
 
    Other deferred charges primarily represent legal and other charges incurred
relating to the preparation of the agreements related to the Company's various
borrowing instruments, and are amortized over the respective financing periods
of each instrument (seven to 20 years).
 
IMPAIRMENT OF LONG-LIVED ASSETS
 
    Effective January 1, 1996, the Company implemented the provisions of
Statement of Financial Accounting Standards ("SFAS") No. 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of." Under SFAS No. 121, the Company is required to review long-lived assets and
certain identifiable intangibles for impairment whenever events or changes in
circumstances indicate that the book value of a long-lived asset is not
recoverable. An impairment loss would be recognized whenever the review
demonstrates that the book value of a long-lived asset is not recoverable. The
implementation of SFAS No. 121 did not have an impact on the Company's financial
position or results of operations.
 
REVENUES
 
    Revenues from operations primarily consist of charges to customers for
monthly access, cellular airtime, data usage, vertical services, roaming
charges, long-distance charges and equipment sales. Revenues are recognized as
services are rendered. Unbilled revenues, resulting from cellular service
provided from the billing cycle date to the end of each month and from other
cellular carriers' customers using USM's cellular systems for the last half of
each month, are estimated and recorded. Equipment sales are recognized upon
delivery to the customer and reflect charges to customers for cellular telephone
user equipment purchased.
 
ADVERTISING COSTS
 
    The Company expenses advertising costs as incurred. Advertising costs
totaled $41.4 million, $24.4 million and $14.1 million for the years ended
December 31, 1997, 1996 and 1995, respectively.
 
PENSION PLAN
 
    Telephone and Data Systems, Inc. Wireless Companies' Pension Plan (the
"Pension Plan"), a qualified noncontributory defined contribution pension plan,
was adopted effective January 1, 1994. It provides pension benefits for the
employees of USM and its subsidiaries. Under this plan, pension benefits and
costs are calculated separately for each participant and are funded currently.
Pension costs were $1.0 million, $1.5 million and $1.2 million in 1997, 1996 and
1995, respectively.
 
EARNINGS PER SHARE
 
    The Company adopted Statement of Financial Accounting Standards ("SFAS") No.
128, "Earnings per Share," effective December 31, 1997. Earnings per Common
Share for 1996 and 1995 have been

effect on 1996 and increased Earnings per Common Share-Basic by $.02 in 1995.
The adoption of SFAS No. 128 had no effect on Earnings per Common Share-Diluted.
 
    The amounts used in computing Earnings per Common Share and the effect on
income and the weighted average number of Common Series A Common Shares of
dilutive potential common stock are as follows:

    The amount of state net operating loss carryforward (generating a $12.2
million deferred tax asset) available to offset future taxable income, primarily
of the individual subsidiaries which generated the loss, aggregated
approximately $221 million at December 31, 1997 and expires between 1998 and
2012. A valuation allowance has been provided when it is more likely than not
that some portion of the deferred tax asset will not be realized. At December
31, 1997, USM had $7.1 million of federal alternative minimum tax credit
carryforward available to offset regular income tax payable in future years.
 
    USM has certain subsidiaries which are not included in the federal
consolidated income tax return, but file separate tax returns. These
subsidiaries had a federal net operating loss carryforward (generating a $2.5
million deferred tax asset) available to offset future taxable income
aggregating approximately $7.2 million at December 31, 1997 which expires
between 2004 and 2012.

EXCHANGE OF MARKETS WITH BELLSOUTH
 
    In October 1997, USM completed an exchange with BellSouth Corporation.
Pursuant to the exchange, USM received majority interests representing
approximately 4.0 million pops in exchange for majority interests representing
2.0 million pops, minority interests representing 1.2 million pops and a net
amount of $86.7 million in cash. The majority interests USM received are in 12
markets adjacent to its Iowa/Missouri and Wisconsin/Illinois/Indiana clusters.
 
    PURCHASE OF MINORITY INTERESTS BY THE COMPANY FROM TDS
 
    Included in the interests USM acquired in 1996 were minority interests in 13
markets, representing 598,000 pops, for $102.8 million in cash paid to TDS.
These interests were acquired pursuant to an agreement entered into in June 1996
between USM and TDS. Due to the intercompany nature of the transactions, these
acquisitions were recorded at TDS's book value of the interests.
 
    Assuming that the 1997 and 1996 acquisitions discussed above, which were
accounted for as purchases, had taken place on January 1, 1996, unaudited pro

and cash totaling $54.2 million. In addition, the Company will receive
approximately $27.0 million in cash from TDS pursuant to a contract right
termination agreement entered into between the Company and TDS. This agreement
is related to two interests which are to be sold directly by TDS to AirTouch and
which were to be acquired by the Company as part of the June 1996 agreement
between the Company and TDS. The contract right termination agreement will
enable the Company to receive cash equal to the value of the gain the Company
would have realized had it purchased the interests from TDS and sold them to
AirTouch under terms similar to those in the agreement between TDS and AirTouch.
 
    Additionally, the Company has entered into an agreement to sell its minority
interests in two other markets, representing approximately 176,000 pops, for
$37.6 million in cash. The Company expects these pending sales transactions to
be completed during the first half of 1998. The Company anticipates that it will
record significant book gains on these divestitures when the transactions are
completed.
 
6. INVESTMENT IN LICENSES
 
    Investment in licenses consists of the costs incurred in acquiring Federal
Communications Commission ("FCC") licenses or interests in entities which have
filed for or have been awarded FCC licenses to provide cellular service. These
costs include amounts paid to license applicants and owners of interests in
cellular entities awarded licenses and all direct and incremental costs relating
to acquiring the licenses. These costs are capitalized and amortized through
charges to expense over 40 years, upon commencement of operations. Costs
applicable to unsuccessful license applications and acquisitions are charged to
expense. Investment in licenses at December 31, 1997 and 1996, include
approximately $281 million and $322 million, respectively, of goodwill related
to various acquisitions structured to be tax-free.
 
7. REVOLVING CREDIT FACILITY
 
    In August 1997, USM established a $500 million revolving credit facility
with a group of banks ("Revolving Credit Facility"). This seven-year facility
replaces the Company's Revolving Credit Agreement with TDS as its primary
short-term borrowing facility. As of December 31, 1997, no borrowings were
outstanding under the Revolving Credit Facility.
 
    The terms of the Revolving Credit Facility provide for borrowings with
interest, at the London InterBank Offered Rate plus 26.5 basis points (for a
rate of 6.2% at December 31, 1997), due quarterly. No principal under the
Revolving Credit Facility is due until August 29, 2004, on which date the
Revolving Credit Facility terminates and all unpaid principal and accrued
interest thereon are due and payable.

8. 6% ZERO COUPON CONVERTIBLE DEBENTURES
 
    During 1995, the Company sold $745 million principal amount at maturity of
zero coupon 6% yield to maturity convertible debt with proceeds to the Company
of $221.5 million. This 20-year fixed rate debt, in the form of Liquid Yield
Option Notes ("LYONs"), is subordinated to all senior indebtedness of the
Company. At December 31, 1997 and 1996, the Company's senior indebtedness
totaled $260.0 million and $113.7 million, respectively. Each LYON is
convertible at the option of the holder at any time at a conversion rate of
9.475 Common Shares per LYON. Upon conversion, USM may elect to deliver its
Common Shares or cash equal to the market value of the Common Shares. Beginning
June 15, 2000, the LYONs may be redeemed at any time for cash at the option of
USM at the issue price plus accrued original issue discount through the date of
redemption. USM will purchase LYONs, at the option of the holder, as of June 15,
2000, at the issue price plus accrued original issue discount through that date.
USM will have the option of purchasing such LYONs with cash, USM Common Shares
or TDS common equity securities, or any combination thereof. During 1997, 25
LYONs were converted for approximately $7,600 in cash.
 
    The carrying values at December 31, 1997 and 1996 of USM's 6% Zero Coupon
Convertible Debentures, $265.3 million and $250.1 million, respectively, are
greater than their fair values, estimated to be $255.6 million and $248.4
million, respectively. The fair values were estimated using discounted cash flow
analysis. The increase in estimated fair value in 1997 was due to a change in
the incremental borrowing rate.
 
9. 7.25% UNSECURED NOTES
 
    During 1997, the Company sold $250 million principal amount of 7.25% notes
("Notes"), priced to yield 7.33% to maturity. The Notes were sold under the
Company's $400 million shelf registration. The Notes are unsecured and become
due on August 15, 2007. Interest on the Notes is payable on February 15 and
August 15 of each year. The Notes will be redeemable, in whole or in part, at
the option of the Company at any time on or after August 15, 2004, at a
redemption price equal to 100% of the principal amount of the Notes to be
redeemed, plus accrued interest thereon, if any, to the date of redemption.
 
    The carrying value at December 31, 1997 of the Company's 7.25% unsecured
notes, $250 million, is less than its fair value, estimated to be $252.9
million. The fair value was estimated using discounted cash flow analysis.
 
10. VENDOR FINANCING
 
    USM repaid approximately $90.1 million principal amount of borrowings,
representing all amounts outstanding under its long-term vendor financing
agreements, with the proceeds of its 7.25% unsecured notes offering in August
1997. See Note 9--7.25% Unsecured Notes for a discussion of the notes offering.
Scheduled repayments of borrowings under the vendor financing agreements in
1997, all made prior to the final repayment, totaled $13.7 million.
 
    The carrying value at December 31, 1996 of USM's current and long-term
vendor financing, $103.7 million, was approximately equal to its estimated fair
value.
 
    Vendor financing at December 31, 1996 included $101.1 million (including
deferred interest) under a 1994 agreement and $2.6 million assumed pursuant to a
1993 acquisition. The current portion of outstanding vendor financing borrowings
was $23.1 million at December 31, 1996.

TAX-DEFERRED SAVINGS PLAN
 
    USM had reserved 134,011 Common Shares for issue under the TDS Tax-Deferred
Savings Plan, a qualified profit-sharing plan pursuant to Sections 401(a) and
401(k) of the Internal Revenue Code. Participating employees have the option of
investing their contributions in USM Common Shares, TDS Common Shares, American
Paging, Inc. (an 81.9%-owned subsidiary of TDS) Common Shares, Aerial
Communications, Inc. (an 82.5%-owned subsidiary of TDS) Common Shares or five
other nonaffiliated funds.
 
STOCK-BASED COMPENSATION PLANS
 
    USM accounts for stock options, stock appreciation rights ("SARs") and
employee stock purchase plans under Accounting Principles Board ("APB") Opinion
No. 25. No compensation costs have been recognized for the stock option and
employee stock purchase plans. Compensation expense for SARs, measured on the
difference between the SAR prices and the year-end market price of the Common
Shares, aggregated $285,000, ($224,000) and $168,000 in 1997, 1996 and 1995,
respectively. Had compensation cost for all plans been determined consistent
with SFAS No. 123, the Company's net income and earnings per share would have
been reduced to the following pro forma amounts as shown on the next page:

STOCK OPTION AND STOCK APPRECIATION RIGHTS PLAN
 
    USM had reserved 748,596 Common Shares for options granted and to be granted
to key employees. USM has established a Stock Option plan as of November 9, 1994
that provides for the grant of stock options to officers and employees. The
options under the 1994 plan are exercisable from the date of vesting through
November 9, 2004, or thirty days following the date of the employee's
termination of employment, if earlier. Under the 1994 Stock Option Plan, 293,418
stock options were outstanding at December 31, 1997, at a weighted average price
of $30.76 per share. The fair value of each option grant was estimated on the
date of grant using the Black-Scholes option pricing model with the following
weighted-average assumptions used for grants in 1997 and 1996, respectively:
risk-free interest rates of 6.3% and 5.9%; expected dividend yields of zero for
both years; expected lives of 4.8 years and 4.0 years; and expected volatility
of 20.8% and 22.7%.
 
    Stock Appreciation Rights (as amended on February 1, 1991) allow the grantee
to receive an amount in Common Shares or cash, or a combination thereof,
equivalent to the difference between the exercise price and the fair market
value of the Common Shares on the exercise date. At December 31, 1997, 38,050
Common Share SARs and 36,000 Series A Common Share SARs were outstanding at $15
per share. These rights expire from 1998 to 2003 or the date of the person's
termination of employment, if earlier. During

11. COMMON STOCK (CONTINUED)
1997 and 1996, 3,950 and 300 Common Share SARs were exercised, respectively. No
SARs were exercised in 1995. There were no SARs granted in 1997 or 1996.
 
EMPLOYEE STOCK PURCHASE PLAN
 
    USM had 115,498 Common Shares reserved under the 1997 Employee Stock
Purchase Plan ("1997 ESPP"). During 1996, the 1997 ESPP was approved, which
became effective January 1, 1997. The fair value of the employees' purchase
rights was estimated on the date of grant using the Black-Scholes option pricing
model with the following weighted-average assumptions used for grants rights in
1997: risk-free interest rate of 5.7%; expected dividend yield of zero; expected
life of .7 years; and expected volatility of 17.6%.
 
SERIES A COMMON SHARES
 
    Series A Common Shares are convertible on a share-for-share basis into
Common Shares and each share is entitled to ten votes per share, compared to one
vote for each Common Share. As of December 31, 1997, all of USM's outstanding
Series A Common Shares were held by TDS.
 
12. RELATED PARTIES
 
    USM is billed for all services it receives from TDS, consisting primarily of
information processing and general management services. Such billings are based
on expenses specifically identified to USM and on allocations of common
expenses. Such allocations are based on the relationship of USM's assets,
employees, investment in plant and expenses to the total assets, employees,
investment in plant and expenses of TDS. Management believes the method used to
allocate common expenses is reasonable and that all expenses and costs
applicable to USM are reflected in the accompanying financial statements on a
basis which is representative of what they would have been if USM operated on a
stand-alone basis. Billings to USM from TDS totaled $36.2 million, $28.1 million
and $26.1 million in 1997, 1996 and 1995, respectively.
 
    USM has a Cash Management Agreement with TDS under which USM may from time
to time deposit its excess cash with TDS for investment under TDS's cash
management program. Deposits made under the agreement are available to USM on
demand and bear interest each month at the 30-day Commercial Paper Rate as
reported in The Wall Street Journal, plus 1/4%, or such higher rate as TDS may
at its discretion offer on such deposits. Interest income from such deposits was
$1.3 million, $4.8 million and $701,000 in 1997, 1996 and 1995, respectively.
 
    Subject to the completion of the Merger, TDS intends to terminate certain
intercompany agreements between TDS and USM. See Note 1--Proposed TDS Corporate
Restructuring for a discussion of the proposed merger.
 
    All markets managed by USM are billed for services they receive from USM.
Such billings are based on expenses specifically identified to each market and
on allocations of common expenses. Such allocations are primarily based on the
relationships of each market's assets and revenues to the total assets and
revenues of all the markets managed by USM. Management believes that all
expenses and costs applicable to each market are representative of what they
would have been if each managed market operated on a stand-alone basis.

13. COMMITMENTS AND CONTINGENCIES
 
CONSTRUCTION AND EXPANSION
 
    The partnerships and corporations in which USM is a partner or shareholder
are in various stages of development. USM expects to spend approximately $330
million during 1998, including about $240 million for new cell sites to expand
and enhance the Company's coverage in its service areas and about $90 million
for the enhancement of the Company's office systems. Under the terms of certain
partnership and shareholder agreements, USM may be committed to funding other
partners' or shareholders' portions of construction and other costs, if
sufficient financing is not available to the individual entities. USM does not
expect such individual financing shortfalls to be material.
 
    From time to time USM may acquire attractive markets to maximize its
clustering strategy. See Note 5--Acquisitions, Exchanges and Divestitures for a
discussion of pending acquisitions and divestitures.
 
LEASE COMMITMENTS
 
    USM and certain of its majority-owned partnerships and subsidiaries lease
certain office and cell site locations under operating leases. Future minimum
rental payments required under operating leases that have noncancelable lease
terms in excess of one year as of December 31, 1997 are as follows:

    Rent expense totaled $17.2 million, $12.4 million and $9.8 million in 1997,

LEGAL PROCEEDINGS
 
    The Company is involved in a number of legal proceedings before the FCC and
various state and federal courts from time to time. Management does not believe
that any of such proceedings should have a material adverse impact on the
financial position or results of operations of the Company.
 
    On December 29, 1997, a party, which claims to be a holder of the USM Common
Shares, filed a putative class action complaint on behalf of common stockholders
of USM in the Court of Chancery of the State of Delaware in New Castle County.
The complaint names as defendants TDS, USM and the directors of USM. The
complaint alleges a breach of fiduciary duties by the defendants and seeks to

    As of December 31, 1997, USM followed the equity method of accounting for
minority interests in 51 markets where the Company's ownership interest is 3% or
greater. This method recognizes, on a current basis, USM's proportionate share
of the incomes and losses accruing to it under the terms of the respective
partnership and shareholder agreements.
 
    As of December 31, 1997, USM follows the cost method of accounting for its
investments in seven markets where the Company's ownership interest is less than
3%. It is not practicable to estimate the fair value of USM's investments
accounted for using the cost method due to the lack of quoted market prices and
the inability to estimate fair values without incurring excessive costs. The
$2.0 million and $9.5 million carrying amounts at December 31, 1997, and 1996,
respectively, represent primarily the original amounts invested, which
management believes are not impaired.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
TO THE SHAREHOLDERS AND BOARD OF DIRECTORS
 
OF UNITED STATES CELLULAR CORPORATION:
 
    We have audited the accompanying consolidated balance sheets of United
States Cellular Corporation (a Delaware corporation and an 81.1%-owned
subsidiary of Telephone and Data Systems, Inc.) and Subsidiaries as of December
31, 1997 and 1996, and the related consolidated statements of operations,
changes in common shareholders' equity and cash flows for each of the three
years in the period ended December 31, 1997. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated 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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of United
States Cellular Corporation and Subsidiaries as of December 31, 1997 and 1996,
and the results of their operations and their cash flows for each of the three
years in the period ended December 31, 1997, in conformity with generally
accepted accounting principles.
