                                  THE COMPANY
 
     We are a leading provider of engineering, construction and maintenance
services to telecommunications and utility providers throughout the United
States. Our comprehensive range of services include:
 
          - telecommunications services:
 
           - the engineering, placement and maintenance of aerial, underground
             and buried cable systems owned by telephone companies, competitive
             access providers and cable television providers;
 
           - the installation of integrated voice, data, and video local and
             wide area networks within office buildings and similar structures;
 
             - the installation of direct broadcast satellite systems;
 
          - underground utility locating services used to map and mark
            underground utilities; and
 
          - power line construction and maintenance services.
 
     For the six-month period ended January 31, 1999, telecommunications
services contributed approximately 90% of our contract revenues, underground
utility locating services contributed approximately 5% and electrical
construction and maintenance services contributed approximately 5%.
 
     We operate through fourteen wholly-owned, independently operating
subsidiaries. We have long-standing relationships with telecommunications and
utility providers such as BellSouth Telecommunications, Inc., Comcast Cable
Communications, Inc., MediaOne, Inc., Tele-Communications, Inc., Sprint
Corporation, GTE Corporation, U.S. West Communications, Inc. and Florida Power
and Light Company. For the six-month period ended January 31, 1999,
approximately 88% of our revenues came from multi-year master service agreements
and other long-term agreements with large telecommunications providers and
electric utilities.
 
     The telecommunications industry is undergoing rapid change due to
deregulation, increased competition and growing consumer demand for enhanced
telecommunications services, thereby creating demand for engineering and
construction of additional infrastructure for new and existing
telecommunications providers. To meet the increasing need for telecommunications
infrastructure, telecommunications providers have been increasingly outsourcing
their infrastructure engineering, construction and maintenance requirements to
reduce investment in capital equipment, improve flexibility in workforce
scheduling, expand geographically without incremental hiring and focus on their
core competencies. As a result, we believe there are significant opportunities
to expand our business internally and through acquisitions.

     Internal Growth Strategy:  Our internal growth strategy has four principal
elements:
 
          - Increase the volume of services to our existing customers;
 
          - Expand the scope of services to our existing customers;
 
          - Broaden our customer base; and
 
          - Geographically expand our service area.
 
     Acquisition Strategy:  We have pursued a strategy of selective acquisitions
involving established, well respected construction and service companies. We
believe a variety of acquisition opportunities exist within our industry to
provide us with customer, geographic and product line diversification. Our key
acquisition criteria are profitability in excess of industry standards, stable
and growing customer base, proven operational and technical competence, and
experienced management that fits with our decentralized operating structure. We
recently acquired the following companies:
 
          - Locating, Inc.  In February 1999, we acquired this Washington
            state-based company which provides underground utility locating
            services used to map and mark utilities for cable television
            providers, multiple system operators, telephone companies and
            electrical and gas utilities. This acquisition expands our presence
            in the underground utility locating services industry and our
            geographic presence in the West Coast region of the United States.
 
          - Ervin Cable Construction, Inc.  In March 1999, we acquired this
            Kentucky-based company, which builds and installs new cable
            television systems and provides repair and expansion services to
            cable television systems in several states. This acquisition expands
            and diversifies our client base and furthers our presence in the
            Midwest region of the United States.
 
          - Apex Digital TV, Inc.  In March 1999, we acquired this
            Kentucky-based company, which installs direct broadcast satellite
            systems and provides cable sales and repair services in several
            Midwestern states. This acquisition provides us an extension into a
            related new business line.
 
On a pro forma basis, these acquisitions would have provided us with additional
revenues of approximately $68.6 million and $33.8 million for the fiscal year
ended July 31, 1998 and the six-month period ended January 31, 1999,
respectively.

           SUMMARY HISTORICAL AND UNAUDITED PRO FORMA FINANCIAL DATA
 
     Set forth below is certain of our historical consolidated financial
information as well as certain consolidated pro forma financial information.
 
     The consolidated financial data as of January 31, 1999 and for the six
months ended January 31, 1998 and 1999 are derived from our unaudited
consolidated financial statements included elsewhere in this prospectus. In the
opinion of management, the unaudited financial statements have been prepared on
the same basis as the audited financial statements and include all adjustments,
which consist only of normal recurring adjustments, necessary for a fair
presentation of the financial position and results of operations for these
periods.
 
     The following pro forma consolidated statements of operations data present
our financial results adjusted for the acquisitions of Locating, ECC and Apex.
Such information is presented as if each of these acquisitions had occurred at
the beginning of the periods presented. The following pro forma consolidated
balance sheet data presents our financial position adjusted for the Locating,
ECC and Apex acquisitions as if each of these acquisitions had occurred as of
January 31, 1999.
 
     The supplemental pro forma financial data presents our statements of
operations adjusted to reflect a provision for income taxes on pooled companies
which were previously "S Corporations" and recorded no provision for federal
income taxes.
 
     The summary pro forma financial data does not purport to be indicative of
the results of operations that would have been achieved had such acquisitions
been consummated as of the assumed dates, nor are the results intended to be
indicative of our future results of operations. The following information should
be read in conjunction with our consolidated financial statements and notes
thereto, "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and the Pro Forma Unaudited Condensed Consolidated
Financial Statements included in this prospectus.

                                  RISK FACTORS
 
     Investing in the common stock will provide you with an equity ownership
interest in Dycom. Before you invest in the common stock, you should be aware of
the various risks associated with an investment in our common stock. Such risks
may materially and adversely affect our business, financial condition or results
of operations. In such case, the trading price of the common stock could
decline, and you could lose all or part of your investment. You should carefully
consider the following factors as well as other information contained in this
prospectus before deciding to invest in the common stock.
 
OUR QUARTERLY OPERATING RESULTS MAY FLUCTUATE SIGNIFICANTLY
 
     We have experienced and expect to continue to experience quarterly
variations in revenues and net income as a result of many factors, including:
 
          - the timing and volume of customers' construction and maintenance
            projects,
 
          - budgetary spending patterns of customers,
 
          - the commencement or termination of master service agreements and
            other long-term agreements with our customers,
 
          - costs incurred to support growth internally or through acquisitions,
 
          - fluctuations in results of operations caused by acquisitions,
 
          - changes in our mix of customers, contracts and business activities,
            and
 
          - fluctuations in insurance expense accruals due to changes in claims
            experience and actuarial assumptions.
 
     Revenues and net income in our second quarter and, occasionally, our third
quarter have in the past been, and may in the future be, adversely affected by
weather conditions and year-end budgetary spending patterns of our customers.
 
WE DEPEND ON A SMALL GROUP OF KEY CUSTOMERS
 
     Our customer base is highly concentrated. Our top five customers in fiscal
1996, 1997, 1998 and the six months ended January 31, 1999 accounted in the
aggregate for approximately 68%, 63%, 65% and 63%, respectively, of our total
contract revenues. During fiscal 1998 and the six months ended January 31, 1999,
approximately 22% and 23%, respectively, of our total contract revenues were
derived from BellSouth Telecommunications, Inc., 24% and 21%, respectively, from
Comcast Cable Communications, Inc. and 7% and 5%, respectively, from GTE
Corporation. We believe that a substantial portion of our contract revenues and
operating income will continue to be derived from a concentrated group of key
customers. The loss of any key customer, if not replaced, could have a material
adverse effect on our business.
 
OUR MASTER SERVICE AGREEMENTS MAY BE TERMINATED OR MAY NOT BE RENEWED
 
     We derive a substantial portion of revenues pursuant to multi-year master
service agreements. We are currently a party to 52 master service agreements,
including 33 such agreements with BellSouth Telecommunications, Inc., GTE
Corporation, Sprint Corporation, U.S. West Communications, Inc. and Florida
Power and Light Company, collectively. Under the terms of these agreements, our
customers can typically terminate the agreement on 90 days prior written notice.
The termination of any such agreements or our failure to renew master service
agreements with our customers could have a material adverse effect on our
business.
 
OUR CUSTOMERS' FUTURE REQUIREMENTS MAY BE LESS THAN OUR BACKLOG ESTIMATE
 
     Our backlog is comprised of the uncompleted portion of services to be
performed under job-specific agreements and the estimated value of future
services that we expect to provide our customers under
 
                                        7
<PAGE>   10
 
master service agreements. Our master service agreements are generally exclusive
requirements contracts with certain exceptions, including the customer's option
to perform the services with its own regularly employed personnel. Accordingly,
there can be no assurance as to our customers' requirements during a particular
period or that our estimates of such requirements, including those used to
formulate backlog, are accurate at any point in time.
 
WE MAY NOT BE ABLE TO SUCCESSFULLY IMPLEMENT OUR ACQUISITION STRATEGY
 
     As part of our growth strategy, we may acquire companies that expand,
complement or diversify our business. We regularly review various strategic
acquisition opportunities and periodically engage in discussions regarding such
possible acquisitions. We cannot assure you that we will be able to identify
attractive acquisition candidates, enter into acceptable acquisition agreements
or close any such transactions. Currently, we are not party to any agreements,
understandings or arrangements regarding any material acquisitions. Failure to
achieve our acquisition strategy could materially and adversely affect our
ability to sustain growth and maintain our competitive position. In addition,
increased competition for acquisition candidates could increase the cost of
making acquisitions and reduce the number of attractive companies to be
acquired. Although we maintain a decentralized operating structure, we may
encounter difficulties in integrating acquired companies or their management
teams. We may also encounter difficulties in retaining key personnel or
customers. These difficulties could increase the cost of any acquisition or
reduce or eliminate any expected benefit. In addition, acquisitions may have
adverse effects on our results of operations caused by amortization of acquired
intangible assets or unanticipated liabilities or contingencies.
 
     We may be required to incur debt or issue equity to pay for any future
acquisitions, and these sources of financing may not be available to us on
favorable terms or at all. In addition, if we use common stock to pay for future
acquisitions, the value of your common stock may become diluted. If we cannot
use common stock or borrow sufficient funds to pay for future acquisitions, our
growth strategy could be limited.
 
WE FACE INTENSE COMPETITION
 
     The telecommunications services industry is highly competitive and we
compete with other companies in most of the markets in which we operate. Some of
our competitors may have greater financial, technical and marketing resources
than we do. A significant portion of our revenues are currently derived from
master service agreements and price is often an important factor in the award of
such agreements. Accordingly, we could be outbid by our competitors in an effort
to procure such business. Despite the current trend toward outsourcing, we may
also face competition from existing or prospective customers who employ in-house
personnel to perform some of the same types of services as we provide. In
addition, there are relatively few, if any, significant barriers to entry into
the markets in which we operate and, as a result, any organization that has
adequate financial resources and access to technical expertise may become one of
our competitors.
 
FUTURE DEVELOPMENTS IN THE TELECOMMUNICATIONS INDUSTRY MAY REDUCE DEMAND FOR OUR
SERVICES
 
     Certain factors related to the telecommunications industry may affect the
demand for the services which we provide. The telecommunications providers may
be unable to raise the capital necessary to develop the telecommunications
networks. There may be a disappointing public demand for Internet access and
other interactive multimedia services or decreases in the preference of our
customers toward outsourcing telecommunications engineering, construction and
maintenance services. In addition, wireline telecommunications systems may be
displaced by other technologies, such as wireless technologies, and improvements
in technology may allow telecommunications providers to significantly improve
their networks without physically upgrading them. Although changes in
telecommunications regulations do not affect us directly, the effect of such
regulations on our customers may, in turn, adversely impact our business and
results of operations.
 
                                        8
<PAGE>   11
 
WE MAY FACE RISKS RELATED TO YEAR 2000 PROBLEMS
 
     Year 2000 technology risks refer to the potential harm resulting from
computer programs that identify dates by the last two digits of the year rather
than using the full four digits. As such, dates as of January 1, 2000 could be
misidentified and such programs could fail. We have reviewed our computer
systems to identify those areas that could be adversely affected by year 2000
software failures. We have converted approximately 85% of our information
systems to be year 2000 compliant. We have incurred approximately $1.4 million
through January 31, 1999 and will incur approximately $0.5 million in the
remainder of fiscal 1999 to complete the information system conversions,
including the implementation and conversion costs of our recently acquired
subsidiaries. Although we expect that any additional expenditures that may be
required for the year 2000 conversions will not be material, there can be no
assurance in this regard. Additionally, we believe that the year 2000 problem
could have a negative impact on certain of our customers and other entities with
which we transact business, which may have a material adverse effect on our
business.
 
WE ARE SELF-INSURED AGAINST POTENTIAL LIABILITIES
 
     We are primarily self-insured, up to a limited amount, for automobile,
general liability, workers' compensation and employee group health claims. A
liability for unpaid claims and associated expenses, including incurred but not
reported losses, is actuarially determined and reflected in our consolidated
balance sheet as an accrued liability. The determination of such claims and
expenses and the extent of the accrued liability are continually reviewed and
updated. If we were to experience insurance claims or costs above our estimates
and were unable to offset such increases with earnings, our business could be
materially and adversely affected.
 
WE ARE DEPENDENT ON KEY PERSONNEL
 
     We are highly dependent upon the continued services and experience of our
senior management team, including Thomas R. Pledger, our Executive Chairman and
Chairman of the Board of Directors, Steven Nielsen, our President and Chief
Executive Officer, and one or more managers of key operating subsidiaries. The
loss of the services of these individuals or other members of our senior
management could have a material adverse effect on our business.
 
OUR COMMON STOCK PRICE MAY BE VOLATILE
 
     The market price for our common stock has been, and may continue to be,
highly volatile. Numerous factors could have a significant effect on the market
price of our common stock. Such factors include the announcements of
fluctuations in operating results, new contracts or customers and acquisitions
by either us or one of our competitors. The market price of our common stock is
also influenced by market conditions for telecommunications or
telecommunications services company stocks in general and by changes in
recommendations or earnings estimates by securities analysts. In addition, the
stock market has experienced significant price and volume fluctuations in recent
years that have been unrelated or disproportionate to the operating performance
of companies. These broad fluctuations may adversely affect the market price of
our common stock.
 
FUTURE SALES OF OUR COMMON STOCK COULD ADVERSELY AFFECT OUR STOCK PRICE
 
     Future sales of substantial amounts of our common stock in the public
market, including the shares covered by this prospectus, or the perception that
such sales could occur, could adversely affect the market price of our common
stock. As of April 27, 1999, we had outstanding 23,046,063 shares of common
stock, plus 886,865 shares of common stock reserved for issuance upon exercise
of outstanding options, including 80,868 options which are currently
exercisable. Substantially all of the outstanding shares of our common stock are
either freely salable or salable subject to certain volume and manner of sale
restrictions pursuant to Rule 144 of the Securities Act of 1933.
 
                                        9
<PAGE>   12
 
     In connection with the acquisition of Communications Construction Group,
Inc. ("CCG"), Cable Com Inc. ("CCI"), Installation Technicians, Inc. ("ITI"),
ECC and Apex, we issued an aggregate of 6,554,057 shares of common stock to
their stockholders. As of April 27, 1999, 1,817,046 of these shares were still
available for future sale by such holders. Holders who received these shares
hold their shares subject to the limitations of Rule 144. We have granted these
holders certain registration rights. Former stockholders of CCI, ITI, ECC and
Apex have the right to have their shares of common stock included in certain
registration statements covering the sale of securities by Dycom or the sale of
common stock by selling stockholders.
 
ANTI-TAKEOVER PROVISIONS MAY INHIBIT CHANGES OF CONTROL
 
     Our articles of incorporation and by-laws contain provisions which may
deter, discourage or make more difficult a takeover or change of control of
Dycom by another corporation. These anti-takeover provisions include:
 
          - the authority of our board of directors to issue up to 1,000,000
            shares of preferred stock without stockholder approval on such terms
            and with such rights as our board of directors may determine, and
 
          - the requirement of a classified board of directors serving staggered
            three-year terms.
 
     We have also adopted a shareholder rights plan and have executed change of
control agreements with key officers, which may make it more difficult to effect
a change in control of Dycom and replace incumbent management. Lastly, we are
subject to certain anti-takeover provisions of the Florida Business Corporation
Act. These anti-takeover provisions could discourage or prevent a change of
control even if such change of control would be beneficial to stockholders and
could adversely affect the market price of our common stock.

<PAGE>   13
 
                                USE OF PROCEEDS
 
     We estimate that we will receive net proceeds from the sale of the
2,500,000 shares of common stock offered by us, after deducting underwriting
discounts and estimated expenses payable by us, of $114.8 million ($132.1
million if the underwriters' over-allotment options are exercised in full). We
will not receive any proceeds from the sale of shares of common stock offered by
the selling stockholders.
 
     We intend to use the net proceeds of the offering to fund our growth
strategy, including acquisitions, working capital and capital expenditures and
for other general corporate purposes. We also intend to use the net proceeds of
the offering to repay approximately $35.7 million of indebtedness under our
revolving credit facility, subject to reborrowings.
 
     The indebtedness to be repaid out of the net proceeds from the offering
bears interest averaging 6.8% per annum and its maturity is up to 45 months.
This indebtedness was incurred under our revolving credit facility in connection
with the acquisitions of Locating and ECC. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources" and Note 8 of the Notes to Consolidated Financial Statements
for a further description of our indebtedness.
 
                PRICE RANGE OF COMMON STOCK AND DIVIDEND POLICY
 
     Our common stock is traded on the New York Stock Exchange under the symbol
"DY." The following table sets forth, for the periods indicated, the high and
low closing sale prices of our common stock as reported on the New York Stock
Exchange. The table has been adjusted to reflect the 3-for-2 stock split
effected in the form of a stock dividend and paid in January 1999.

     On May 13, 1999, the closing sale price of our common stock as reported on
the New York Stock Exchange was $50 1/16 per share. The number of stockholders
of record on April 27, 1999 was approximately 640.
 
     Since 1982 we have not paid any cash dividends and we currently intend to
continue to retain future earnings. Our board of directors will determine any
future change in dividend policies based on financial conditions, profitability,
cash flow, capital requirements, and business outlook, as well as other factors
relevant at the time. Our credit facility expressly limits the payment of cash
dividends to fifty percent of each fiscal year's net income. The credit
facility's restrictions regarding our debt to net worth, quick and current
ratios also affect our ability to pay dividends.

                      SUMMARY CONSOLIDATED FINANCIAL DATA
 
     The following table sets forth our summary consolidated financial data for
the periods indicated including certain consolidated pro forma financial
information.
 
     The summary consolidated financial data as of July 31, 1997 and 1998 and
for each of the three years in the period ended July 31, 1998 are derived from
our consolidated financial statements included elsewhere in this prospectus that
have been audited by Deloitte & Touche LLP, independent auditors, as stated in
their report, which is included elsewhere in this prospectus. The summary
consolidated balance sheet data as of July 31, 1996 has also been derived from
audited financial statements. The financial statements of CCG (consolidated with
our financial statements, and not presented herein) have been audited by Nowalk
& Associates, independent auditors, as stated in their report, which is included
herein and incorporated by reference herein. Our Consolidated Financial
Statements and all financial and operating data derived therefrom have been
combined for all periods presented to include the financial condition and
results of operations of CCG, CCI and ITI.
 
     The summary consolidated financial data as of January 31, 1999 and for the
six months ended January 31, 1998 and 1999 are derived from our unaudited
financial statements included elsewhere in this prospectus and include all
adjustments (consisting only of normal recurring adjustments) which are
necessary to present fairly the results of operations and financial position for
such periods. The results for the six months ended January 31, 1999 are not
necessarily indicative of the results to be expected for the full year.
 
     The pro forma statements of operations data present our financial position
adjusted for the acquisitions of Locating, ECC and Apex. Such information is
presented as if each of these acquisitions had occurred at the beginning of the
periods presented. The pro forma balance sheet data presents our financial
position adjusted for the Locating, ECC and Apex acquisitions as if each of
these acquisitions had occurred as of January 31, 1999.
 
     The supplemental pro forma data presents our statements of operations
adjusted to reflect a provision for income taxes on pooled companies which were
previously "S Corporations" and recorded no provision for income taxes.
 
     The summary pro forma data does not purport to be indicative of the results
of operations that would have been achieved had such acquisitions been
consummated as of the assumed dates, nor are the results intended to be
indicative of our future results of operations. The following data should be
read in conjunction with, and is qualified in its entirety by reference to, our
consolidated financial statements and notes thereto, "Management's Discussion
and Analysis of Financial Condition and Results of Operations" and the Pro Forma
Unaudited Condensed Consolidated Financial Statements included elsewhere in this
prospectus and the individual financial statements and notes thereto of certain
acquired businesses incorporated by reference herein.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
     We derive most of our contract revenues earned from engineering,
construction and maintenance services to the telecommunications industry.
Additionally, we provide similar services related to the installation of
integrated voice, data and video, local and wide area networks within office
buildings and similar structures and also perform underground utility locating
and electric utility contracting services. We currently perform work for more
than 25 local exchange carriers, cable television multiple system operators,
long distance carriers, competitive access providers, and electric utilities
throughout the United States. We expect that future growth in contract revenues
earned will be generated from (i) increasing the volume of services to existing
customers; (ii) expanding the scope of services to existing customers; (iii)
broadening our customer base; and (iv) geographically expanding our service
area. We expect to grow through internal sources as well as through
acquisitions. Other revenues include interest income and gain on sale of surplus
equipment.
 
     In July 1997, we completed the acquisition of CCG and in April 1998, we
completed the acquisitions of CCI and ITI. Each of these transactions was
accounted for as a pooling of interests. Our financial statements and all
financial and operating data derived therefrom have been combined for all
periods presented herein to include the financial condition and results of
operations of CCG, CCI and ITI. CCG and CCI provide construction services to
cable television multiple system operators, and ITI provides construction and
engineering services to local and long distance telephone companies.
 
     We provide services to our customers pursuant to multi-year master service
agreements and other long- and short-term contracts for particular projects.
Under master service agreements, we agree to provide, for a period of several
years, all specified service requirements to our customer within a given
geographical territory. Under the terms of such agreements, the customer can
typically terminate the agreement with 90 days prior written notice. The
customer, with certain exceptions, agrees to purchase such requirements from us.
Materials to be used in these jobs are generally provided by the customer.
Master service agreements generally provide that we will furnish a specified
unit of service for a specified unit price (e.g., fiber optic cable will be
installed underground for a specified rate of dollars per foot). We recognize
revenue under master service agreements as the related work is performed. We are
currently a party to 52 master service agreements, which may be either bid or
negotiated. Master service agreements are typically bid initially and may be
extended by negotiation. The remainder of our services are provided pursuant to
contracts for particular jobs. Long-term contracts relating to specific projects
have terms in excess of one year from the contract date. Short-term contracts
are generally from three to four months in duration from the contract date,
depending upon the size of the project. Contract revenues from multi-year master
service agreements and other long-term agreements represented 90% and 88%,
respectively, of total contract revenues in fiscal 1998 and for the six-month
period ended January 31, 1999. Contract revenues for fiscal 1998 and for the
six-month period ended January 31, 1999 from multi-year master service
agreements represented 49% and 47%, respectively, of total contract revenues.
 
     Cost of earned revenues includes all direct costs of providing services
under our contracts, other than depreciation on fixed assets owned by us or
utilized by us under capital leases, which are included in depreciation and
amortization expense. Cost of earned revenues includes all costs of construction
personnel, subcontractor costs, all costs associated with operation of
equipment, excluding depreciation, materials not supplied by the customer and
insurance. Because we are primarily self-insured for automobile and general
liability, workers' compensation, and employee group health claims, a change in
experience or actuarial assumptions that did not affect the rate of claims
payments could nonetheless materially adversely affect results of operations in
a particular period. General and administrative costs include all costs of
holding company and subsidiary management personnel, rent, utilities, travel and
centralized costs such as insurance administration, interest on debt,
professional costs and certain clerical and administrative overhead. Our
management personnel, including subsidiary management, undertake all
 
                                       15
<PAGE>   18
 
sales and marketing functions as part of their management responsibilities and,
accordingly, we do not incur material selling expenses.
 
     We were founded in 1969 and witnessed significant growth during the 1980's
as the result of increasing competitive growth in the long distance telephone
market and the needs of the long distance carriers to replace their copper
cabling with fiber optic cable. Through 1990, we acquired nine operating
subsidiaries. As long distance carriers completed most of their long haul lines
in the late 1980's, we shifted our focus to the local exchange carrier market.
During the early 1990's, our results of operations were materially adversely
affected by a number of internal developments, including (i) adjustments taken
to insurance reserves in fiscal 1991, (ii) write-offs of intangible assets,
including goodwill, of $24.3 million and $1.4 million in fiscal 1993 and fiscal
1994, respectively, incurred in connection with four acquisitions, which
contributed to substantial net losses in those years, and (iii) significant
costs and distraction of management attention associated with a range of
litigation and a governmental investigation, including shareholder litigation
and protracted litigation with a former officer involved in a takeover effort.
All of these matters were concluded in or before fiscal 1995. We do not believe
that any of the events or circumstances we faced in the early 1990's are
indicative of the manner in which we currently operate or future prospects.
 
RECENT ACQUISITIONS
 
     In February 1999, we acquired Locating, a Washington state-based company,
for $10.0 million. Locating provides underground utility locating services used
to map and mark utilities for cable television providers, multiple system
operators, telephone companies and electrical and gas utilities. Locating will
operate as a wholly-owned subsidiary of Dycom.
 
     In March 1999, we completed the acquisitions of ECC, a Kentucky-based
company that builds and installs new cable television systems and provides
repair and expansion services to cable television systems in several states, and
Apex, also a Kentucky-based company, which installs direct broadcast satellite
systems and provides cable sales and repair services in several states, for an
aggregate purchase price of $21,750,000 and 774,194 shares of our common stock.
Prior to the acquisitions of ECC and Apex, the three stockholders of ECC owned
80% of the outstanding shares of common stock of Apex. Both ECC and Apex will
operate as wholly-owned subsidiaries of Dycom.
 
     On a pro forma basis, these acquisitions would have provided us with
additional revenues of $68.6 million and $33.8 million for the fiscal year ended
July 31, 1998 and the six-month period ended January 31, 1999, respectively. See
the Pro Forma Unaudited Condensed Consolidated Financial Statements included in
this prospectus.

    taxes. See Note 1 of the Notes to Consolidated Financial Statements.
 
SIX MONTHS ENDED JANUARY 31, 1999 COMPARED TO SIX MONTHS ENDED JANUARY 31, 1998
 
     Revenues.  For the six-month period ended January 31, 1999, contract
revenues increased $33.5 million, or 19.5%, to $205.3 million as compared to
$171.8 million for the corresponding period in the previous fiscal year. Of this
increase, $32.3 million was attributable to the telecommunications services
group, $1.0 million was attributable to the underground utility locating
services group, and $0.2 million was attributable to the electrical construction
and maintenance services group, reflecting an increased market demand for our
services.
 
     During the six-month period ended January 31, 1999, we recognized $185.7
million of contract revenues from the telecommunications services group as
compared to $153.4 million for the same period in the previous fiscal year, an
increase of 21.1%. The increase in our telecommunications services group
contract revenues reflects increased volume of projects and activities
associated with cable television construction services which increased by $10.8
million to $84.0 million in the six-month period ended January 31, 1999. Of the
remaining $21.5 million increase in telecommunications contract revenues, $16.1
million related to geographic expansion and an increased volume of services to
existing customers under the terms of several new master service agreements.
Contract revenues recognized from the electrical construction and maintenance
services group was $10.1 million and $9.9 million, respectively, for the six
months ended January 31, 1999 and 1998. We recognized contract revenues of $9.5
million from the underground utility locating services group in the six months
ended January 31, 1999 as compared to $8.5 million in the same period last year,
an increase of 11.2%.
 
     Contract revenues from multi-year master service agreements and other
long-term agreements represented 88% and 89% of total contract revenues in the
six months ended January 31, 1999 and 1998, respectively. Contract revenues from
multi-year master service agreements represented 47% of total contract revenues
in each of the six months ended January 31, 1999 and 1998.
                                       17

     Costs of Earned Revenues.  Costs of earned revenues increased $19.6 million
to $154.6 million in the six months ended January 31, 1999 from $135.0 million
in the six months ended January 31, 1998, but decreased as a percentage of
contract revenues to 75.3% from 78.5%. Insurance and equipment costs declined as
a percentage of contract revenues as a result of effective management of
insurance claims, positive results of the corporate safety program, and the
buy-out of certain operating leases. Other factors affecting the improved
operating margin include increased productivity of our labor force combined with
the effective utilization of subcontractors to meet labor demands.
 
     General and Administrative Expenses.  General and administrative expenses
increased $4.2 million to $20.2 million in the six months ended January 31, 1999
from $16.0 million in the six months ended January 31, 1998. The increase in
general and administrative expenses for the six months ended January 31, 1999,
as compared to the same period last year, was primarily attributable to
increases in administrative salaries, employee benefits and payroll taxes of
$3.0 million, registration costs of $0.4 million, and other general and
administrative expenses of $1.2 million offset by a reduction in interest costs
of $0.4 million associated with the declining balance of notes payable.
 
     Depreciation and Amortization.  Depreciation and amortization increased
$1.8 million to $8.1 million in the six months ending January 31, 1999 as
compared to $6.3 million in the same period last year. The increase in
depreciation and amortization was due to capital expenditures of $22.8 million
in the six-month period ended January 31, 1999 as compared to $10.0 million in
the six-month period ended January 31, 1998, an increase of $12.8 million. The
increased purchases represent capital expenditures in the ordinary course of
business, equipment purchased for the start-up of certain long-term contracts,
and the buy-out of operating leases on terms favorable to us.
 
     Income Taxes.  The provision for income taxes was $9.6 million in the
six-month period ended January 31, 1999 as compared to $5.1 million in the same
period last year. Our effective tax rate was 40.5% in the six-month period ended
January 31, 1999 as compared to 32.3% in the same period last year. The
effective tax rate differs from the statutory rate due to state income taxes,
income of Subchapter S Corporations (CCI and ITI) being taxed to their
stockholders, the amortization of intangible assets that do not provide a tax
benefit, and other non-deductible expenses for tax purposes. For the six-month
period ended January 31, 1998, the provision for income taxes has been adjusted
to reflect a pro forma tax provision for pooled companies which were previously
Subchapter S Corporations. The pro forma provision for income taxes was $6.5
million and the pro forma effective tax rate was 41.6% for the six month period
ended January 31, 1998.
 
     Net Income.  Net income increased to $14.1 million for the six-month period
ended January 31, 1999 as compared with net income of $10.6 million in the
corresponding period in fiscal year 1998, a 33.4% increase.
 
YEAR ENDED JULY 31, 1998 COMPARED TO YEAR ENDED JULY 31, 1997
 
     Revenues.  Contract revenues increased $57.5 million, or 18.5%, to $368.7
million in fiscal 1998 from $311.2 million in fiscal 1997. Of this increase,
$51.8 million was attributable to the telecommunications services group, $2.8
million was attributable to the electrical construction and maintenance services
group and $2.9 million was attributable to the underground utility locating
services group, reflecting an increased overall market demand for our services.
 
     During fiscal 1998, we recognized $330.6 million of contract revenues from
the telecommunications services group as compared to $278.8 million in fiscal
1997. The increase in our telecommunications services group contract revenues
reflects an increased volume of projects and activity in fiscal 1998 associated
with cable television services, which increased by $36.9 million to $153.5
million in fiscal 1998 from $116.6 million in fiscal 1997. Contract revenues in
the telecommunications services group also increased for services performed in
the design and installation of broadband networks, telephone engineering
services, telephony splicing services, premise wiring services, and revenues
from services performed under master service agreements. We recognized contract
revenues of $20.2 million from the electrical construction and maintenance
services group in fiscal 1998 as compared to $17.4 million fiscal
 
                                       18
<PAGE>   21
 
1997, an increase of 16.1%. We recognized contract revenues of $17.9 million
from underground utility locating services in fiscal 1998 as compared to $15.0
million in fiscal 1997, an increase of 19.3%.
 
     Contract revenues from multi-year master service agreements and other
long-term agreements represented 90% of total contract revenues in fiscal 1998
as compared to 84% in fiscal 1997, of which contract revenues from multi-year
master service agreements represented 49% of total contract revenues in fiscal
1998 as compared to 51% in fiscal 1997.
 
     Cost of Earned Revenues.  Cost of earned revenues increased $39.0 million
to $285.0 million in fiscal 1998 from $246.0 million in fiscal 1997, but
decreased as a percentage of contract revenues to 77.3% from 79.0%. Direct
materials, equipment costs, and other direct costs declined slightly as a
percentage of contract revenues as a result of improved productivity and the
utilization of more modern equipment.
 
     General and Administrative Expenses.  General and administrative expenses
increased $5.9 million to $36.7 million in fiscal 1998 from $30.8 million in
fiscal 1997, and increased slightly as a percentage of contract revenues to
10.0% from 9.9%. The increase in general and administrative expenses was
primarily attributable to a $2.4 million increase in administrative salaries,
bonuses, employee benefits and payroll taxes and an increase of $1.2 million in
the provision for doubtful accounts. Acquisition and merger related expenses
charged to general and administrative expenses were $0.6 million and $0.4
million in fiscal 1998 and 1997, respectively.
 
     Depreciation and Amortization.  Depreciation and amortization expense
increased $1.7 million to $13.5 million in fiscal 1998 from $11.8 million in
fiscal 1997, but decreased as a percentage of contract revenues to 3.6% from
3.8%. The increase in amount reflects the depreciation of additional capital
expenditures incurred in the ordinary course of business.
 
     Income Taxes.  The provision for income taxes was $13.0 million in fiscal
1998 as compared to $8.0 million in fiscal 1997. The provision for income taxes
for 1998 reflects a reduction of $0.4 million in a valuation allowance relative
to certain deferred tax assets. Our effective tax rate was 36.2% in fiscal 1998
as compared to 33.5% in fiscal 1997. The effective tax rate differs from the
statutory tax rate due to state income taxes, income of Subchapter S
Corporations (CCI and ITI) being taxed to their stockholders, the amortization
of intangible assets that do not provide a tax benefit, other non-deductible
expenses for tax purposes and the reduction in a valuation allowance relative to
certain deferred tax assets. As of the date of the merger, CCI and ITI
recognized a combined deferred tax liability of $0.6 million which was included
in the results of operations for the quarter ended April 30, 1998.
 
     The pro forma provision for income taxes to give effect to pooled S
Corporations was $14.4 million in fiscal 1998 as compared to $9.8 million in
fiscal 1997. The pro forma effective tax rate was 40.0% in fiscal 1998 and 41.4%
in fiscal 1997.
 
     Net Income.  Net income increased to $23.0 million in fiscal 1998 from
$15.8 million in fiscal 1997, a 45.7% increase. Pro forma net income increased
to $21.7 million in fiscal 1998 from $13.9 million in fiscal 1997, a 55.5%
increase.
 
YEAR ENDED JULY 31, 1997 COMPARED TO YEAR ENDED JULY 31, 1996
 
     Revenues.  Contract revenues increased $65.3 million, or 26.6%, to $311.2
million in fiscal 1997 from $245.9 million in fiscal 1996. Of this increase,
$57.3 million was attributable to the telecommunications services group, $6.7
million was attributable to the electrical construction and maintenance services
group and $1.3 million was attributable to the underground utility locating
services group, reflecting an increased overall market demand for our services.
During fiscal 1997, we recognized $278.8 million of contract revenues from the
telecommunications services group as compared to $221.5 million in fiscal 1996.
The increase in our telecommunications services group reflects an increased
volume of projects and activity in fiscal 1997 associated with cable television
services, which increased by $32.4 million to $116.6 million in fiscal 1997 from
$84.2 million in fiscal 1996, the design and installation of broadband networks,
telephony engineering services, and premise wiring services, partially offset by
a slight decline in contract revenues from services performed under master
service agreements. Contract revenues from master service
 
                                       19
<PAGE>   22
 
agreements were a significant source of our revenues, representing approximately
51% of total contract revenues in fiscal 1997 as compared to 56% in fiscal 1996.
We recognized contract revenues of $17.4 million from electrical construction
and maintenance services in fiscal 1997 as compared to $10.7 million in fiscal
1996, an increase of 62.6%. We recognized contract revenues of $15.0 million
from underground utility locating services in fiscal 1997 as compared to $13.7
million in fiscal 1996, an increase of 9.5%.
 
     Contract revenues from long-term agreements represented 84% of total
contract revenues in fiscal 1997 as compared to 87% in fiscal 1996. In addition,
contract revenues from master service agreements continued to be a significant
source of our revenues, representing 51% of total contract revenues in fiscal
1997 as compared to 56% in fiscal 1996.
 
     Costs of Earned Revenues.  Costs of earned revenues increased $47.6 million
to $246.0 million in fiscal 1997 from $198.4 million in fiscal 1996, but
decreased as a percentage of contract revenues to 79.0% from 80.7%. Direct
labor, equipment and materials costs declined slightly as a percentage of
contract revenues as a result of improved productivity in the labor force and
the utilization of more modern equipment. Additionally, insurance costs declined
by approximately $1.6 million as a result of fewer claims arising in fiscal
1997.
 
     General and Administrative Expenses.  General and administrative expenses
increased $6.4 million to $30.8 million in fiscal 1997 from $24.4 million in
fiscal 1996, but remained stable at 9.9% of contract revenues. The increase in
general and administrative expenses was primarily attributable to a $4.1 million
increase in administrative salaries, bonuses, employee benefits and payroll
taxes. We also incurred professional and related expenses associated with the
CCG Acquisition of $0.4 million in fiscal 1997.
 
     Depreciation and Amortization.  Depreciation and amortization expense
increased $1.4 million to $11.8 million in fiscal 1997 from $10.4 million in
fiscal 1996, but decreased as a percentage of contract revenues to 3.8% from
4.3%. The increase in amount reflects the depreciation of additional capital
expenditures incurred in the ordinary course of business.
 
     Income Taxes.  The provision for income taxes was $8.0 million in fiscal
1997 as compared to $4.1 million in fiscal 1996. The provision for income taxes
for fiscal 1996 reflects a reduction of $1.1 million in a valuation allowance
relative to certain deferred tax assets. Our effective tax rate was 33.5% in
fiscal 1997 as compared to 29.4% in fiscal 1996. The effective tax rate differs
from the statutory tax rate due to state income taxes, taxable income of
Subchapter S Corporations (CCI and ITI) being taxed to their stockholders, the
amortization of intangible assets that do not provide a tax benefit, other
non-deductible expenses for tax purposes and, in fiscal 1996, the reduction in a
valuation allowance relative to certain deferred tax assets.
 
     The pro forma provision for income taxes to give effect to pooled S
Corporations was $9.8 million in fiscal 1997 as compared to $4.9 million in
fiscal 1996. The pro forma effective tax rate was 41.4% in fiscal 1997 and 34.6%
in fiscal 1996.
 
     Net Income.  Net income increased to $15.8 million in fiscal 1997 from $9.9
million in fiscal 1996, a 59.4% increase.

     We have historically experienced variability in revenues, income before
income taxes and net income on a quarterly basis. A significant amount of this
variability is due to the fact that our business is subject to seasonal
fluctuations, with activity in our second and occasionally third fiscal quarters
(the quarters ended January 31 and April 30 in a given fiscal year) being
adversely affected by weather. For example, our revenues, income before income
taxes and net income for the second quarter of fiscal 1997 and 1998 were
adversely affected by severe winter weather, including significant snowfall,
experienced during that time. In addition, budgetary spending patterns of
significant customers, which often run on a calendar year basis, have resulted
in greater volatility of second fiscal quarter results. We have witnessed
increased sales of engineering services in recent years, and an increase in the
level of such services may offset the effect of these seasonal factors, although
no assurance can be given.
 
     We have experienced and expect to continue to experience quarterly
fluctuations in revenues, income before income taxes and net income as a result
of other factors, including the timing and volume of customers' construction and
maintenance projects, the commencement, renewal or termination of master service
agreements, safety performance and the timing of additional costs to support
growth by acquisition or otherwise.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Our needs for capital are attributable primarily to our needs for equipment
to support our contractual commitments to customers and our needs for working
capital sufficient for general corporate purposes. Capital expenditures have
been financed by operating and capital leases, bank borrowings and internal cash
 
                                       21
<PAGE>   24
 
flow. To the extent that we seek to grow by acquisitions that involve
consideration other than our stock, our capital requirements may increase,
although we are not currently subject to any commitments or obligations with
respect to any acquisitions. Our sources of cash have historically been from
operating activities, bank borrowings, proceeds arising from the sale of idle
and surplus equipment and real property, and the public offering of our common
stock.
 
     For fiscal 1998, net cash provided by operating activities was $30.6
million compared to $12.8 million for fiscal 1997 and $19.5 million for fiscal
1996. Net income and non-cash charges are the primary sources of operating cash
flow. The increase in net cash provided by operating activities in fiscal 1998
was due primarily to an increase in net income and other non-cash expenses. The
increase was also attributable to funds advanced by a customer for materials and
start-up expenses related to certain long-term construction contracts. The
amounts advanced at July 31, 1998 were $9.4 million. For the six-month period
ended January 31, 1999, net cash provided by operating activities was $24.3
million compared to $10.4 million for the six-month period ended January 31,
1998. Working capital items contributed $2.2 million to operating cash flow for
the six-month period ended January 31, 1999 principally through a decrease in
accounts receivable and an increase in accounts payable offset by an increase in
other current assets and unbilled revenues and a decrease in income taxes
payable.
 
     For fiscal 1998, net cash used in investing activities for capital
expenditures was $21.5 million, compared to $16.1 million in fiscal 1997 and
$13.5 million in fiscal 1996. For fiscal 1998 and fiscal 1997, these capital
expenditures were for the normal replacement of equipment and the buy out of
certain operating leases on terms favorable to us. For fiscal 1996, these
capital expenditures were for normal equipment replacement and for additional
equipment purchases made by the underground utility locating group to service
new geographic areas. In addition to equipment purchases, we obtained
approximately $2.2 million of equipment in fiscal 1998, $3.3 million of
equipment in fiscal 1997, and $3.0 million of equipment in fiscal 1996 under
noncancellable operating leases. In the six-month period ended January 31, 1999,
net cash used in investing activities was $26.0 million as compared to $9.0
million for the same period last year. For the six-month period ended January
31, 1999, capital expenditures of $22.8 million were for the normal replacement
of equipment in the ordinary course of business, equipment purchased for the
start up of certain long-term contracts, and the buy-out of operating leases on
terms favorable to us.
 
     In August 1998, we purchased a 13.0% equity interest in Witten
Technologies, Inc. ("Witten") for $3.0 million. Witten has developed, and is the
owner of, various proprietary technologies and materials relating to
ground-penetrating radar and the use of other electromagnetic frequencies. In
addition to the equity received, we have acquired an exclusive license to market
certain technologies within the United States and Canada. Witten is being
accounted for as an unconsolidated affiliate. Additionally, we purchased assets
of a business, which included a non-compete agreement, for $750,000 for use in
the telecommunications services group.
 
     At January 31, 1999, we had outstanding borrowings of $15.4 million against
our $85.0 million credit facility consisting of (i) $2.6 million of advances
under the equipment and small business purchase facility and (ii) $12.8 million
outstanding under the term-loan facility. The interest rate on the outstanding
equipment advances was at LIBOR plus 1.75% or 7.0% and the interest rate on the
outstanding term loan was at the bank's prime interest rate minus 0.50% or
7.25%. In addition, we had $11.4 million in outstanding letters of credit issued
as security to our insurance administrators as part of our self-insurance
program. At January 31, 1999, we had available borrowing capacity of $22.4
million under the revolving equipment acquisition and small business purchase
facility, $30.0 million under the revolving working capital facility and $3.6
million under the standby letter of credit facility. During the six months ended
January 31, 1999, we repaid $1.5 million on this facility.
 
     Subsequent to January 31, 1999, we utilized the available credit facility
to finance the cash portion of the Locating and ECC acquisitions. The total cash
portion of these acquisitions was $31.8 million.
 
     On April 27, 1999, we signed a $90.25 million amendment to our credit
facility which increases the level of available financing to $175.25 million and
extends the facility's maturity to April 2002. The credit agreement is with a
syndicate of banks led by Dresdner Bank Lateinamerika AG Miami Agency (the
                                       22
<PAGE>   25
 
"Bank") and provides for (i) a $17.5 million standby letter of credit facility,
(ii) a $50.0 million revolving working capital facility, (iii) a $12.75 million
five-year term loan, and (iv) a $95.0 million equipment acquisition and small
business purchase facility. The revolving working capital facility bears
interest at either the LIBOR rate plus 1.25% per annum or the Bank's prime rate
minus 1.125% per annum. The term loan bears interest at either the LIBOR rate
plus 1.75% per annum or the Bank's prime rate minus 0.50% per annum. The
equipment acquisition and small business purchase facility bears interest at
either the LIBOR rate plus 1.50% per annum or the Bank's prime rate minus 0.75%
per annum. The obligations under the amended credit agreement are guaranteed by
our subsidiaries and secured by security interests in certain property and
assets of us and our subsidiaries.
 
     The amended credit agreement requires us to maintain certain financial
covenants and conditions. The amended credit agreement restricts encumbrances on
assets and the creation of additional indebtedness and limits the payment of
cash dividends to fifty percent of each fiscal year's net income. All
obligations under this credit agreement are guaranteed by our subsidiaries and
secured by certain property and assets of Dycom and its subsidiaries.
 
     Our acquired subsidiaries, CCI and ITI, had outstanding credit facilities
prior to our acquisition of such companies. CCI had a $5.2 million revolving
credit facility for funding working capital and a $2.0 million term note
incurred to purchase equipment. ITI had a $2.0 million revolving credit facility
for funding working capital and a $0.5 million multiple advance term facility
for equipment acquisitions. During the fourth quarter of fiscal 1998, we paid
off the outstanding balances of $8.1 million under these facilities with
existing cash balances and subsequently terminated such facilities.
 
     In the six-month period ended January 31, 1999, net cash used in financing
activities was $0.2 million which was primarily attributable to normal debt
payments, under the terms of our bank credit agreement, of $2.4 million offset
by funds received from the exercise of stock options of $2.2 million during the
period.
 
     We foresee our capital resources together with existing cash balances to be
sufficient to meet our financial obligations, including the scheduled debt
payments under our credit agreement and operating lease commitments, and to
support our normal replacement of equipment at our current level of business for
at least the next twelve months. Our future operating results and cash flows may
be affected by a number of factors including our success in bidding on future
contracts and our continued ability to effectively manage controllable costs.
 
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
     In June 1997, the FASB issued SFAS No. 130 "Reporting Comprehensive
Income," which establishes standards for reporting and display of comprehensive
income and its components (revenues, expenses, gains and losses) in a full set
of general purpose financial statements. This statement requires that an
enterprise classify items of other comprehensive income by their nature in a
financial statement and display the accumulated balance of other comprehensive
income separately from retained earnings and additional paid-in capital in the
equity section of a statement of financial position. This statement is effective
for fiscal years beginning after December 15, 1997.
 
     In June 1997, the FASB issued SFAS No. 131 "Disclosure about Segments of an
Enterprise and Related Information," which establishes standards for public
business enterprises to report information about operating segments in annual
financial statements and requires those enterprises to report selected
information about operating segments in interim financial reports issued to
shareholders. It also establishes the standards for related disclosures about
products and services, geographic areas, and major customers. This statement
requires that a public business enterprise report financial and descriptive
information about its reportable operating segments. The financial information
is required to be reported on the basis that it is used internally for
evaluating segment performance and deciding how to allocate resources to
segments. Operating segments are components of an enterprise about which
separate financial information is available that is evaluated regularly by the
chief operating decision maker in deciding how to allocate resources and
 
                                       23

in assessing performance. This statement is effective for financial statements
for periods beginning after December 15, 1997.
 
     In February 1998, the FASB issued SFAS No. 132 "Employees Disclosures About
Pension and Other Postretirement Benefits," which revises certain disclosures
about pension and other postretirement benefit plans. This statement does not
change the measurement and recognition methods for pensions or postretirement
benefits costs reported in financial statements. This statement is effective for
fiscal years beginning after December 15, 1997.
 
     In June 1998, the FASB issued SFAS No. 133 "Accounting for Derivative
Instruments and Hedging Activities," which establishes standards for the
accounting and reporting of derivative instruments, including certain derivative
instruments embedded in other contracts (collectively referred to as
derivatives), and for hedging activities. It requires that an entity recognize
all derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. This statement is
effective for financial statements for periods beginning after June 15, 1999.
 
     We are currently evaluating the requirements and related disclosures of
SFAS No. 130, 131, 132 and 133.
 
YEAR 2000 COMPLIANCE
 
     We have reviewed our computer systems to identify those areas that could be
adversely affected by year 2000 software failures. We have converted
approximately 85% of our information systems to be year 2000 compliant. We have
incurred approximately $1.4 million through January 31, 1999 and will incur
approximately $0.5 million in the remainder of fiscal 1999 to complete the
information system conversions, including the implementation and conversion cost
of our recently acquired subsidiaries. We believe that our systems are year 2000
compliant and any additional expenditures that may be required in connection
with the year 2000 issue are not expected to be material. In addition, we
believe that many of our customers, particularly local exchange and long
distance carriers and cable multiple system operators, are also impacted by the
year 2000 issue, which in turn could affect us. We are assessing the compliance
efforts of our major customers and suppliers. If the systems of certain of our
customers and suppliers, particularly the local exchange and long distance
carriers and cable multiple system operators and others on whose services we
depend or with whom our systems interface, are not year 2000 compliant, it could
have a material adverse effect on us. We will be formulating a contingency plan
prior to the end of the current fiscal year to address the possible side
effects, if any, of our customers and suppliers experiencing year 2000 problems.

                                    BUSINESS
 
OVERVIEW
 
     We are a leading provider of engineering, construction and maintenance
services to telecommunications and utility providers throughout the United
States. Our comprehensive range of telecommunications services include the
engineering, placement and maintenance of aerial, underground, and buried
fiber-optic, coaxial and copper cable systems owned by local and long distance
telephone companies, competitive local exchange carriers, and cable television
multiple system operators. Additionally, we provide similar services related to
the installation of integrated voice, data, and video local and wide area
networks within office buildings and similar structures and the installation of
direct broadcast satellite systems. We also perform underground utility locating
and electric utility contracting services. For fiscal 1998 and for the six-month
period ended January 31, 1999, telecommunications services contributed
approximately 90% of our contract revenues, underground utility locating
services contributed approximately 5% and electrical construction and
maintenance services contributed approximately 5%.
 
     Through our fourteen wholly-owned and independently operating subsidiaries,
we have long-standing relationships with many leading local exchange carriers,
long distance providers, competitive access providers, cable television multiple
system operators and electric utilities. Such key customers include BellSouth
Telecommunications, Inc., Comcast Cable Communications, Inc., MediaOne, Inc.,
Tele-Communications, Inc., Sprint Corporation, GTE Corporation, U.S. West
Communications, Inc. and Florida Power and Light Company. During fiscal 1998 and
the six-month period ended January 31, 1999, approximately 90% and 88%,
respectively, of our revenues came from multi-year master service agreements and
other long-term agreements with large telecommunications providers and electric
utilities.
 
RECENT ACQUISITIONS
 
     In July 1997, we acquired CCG, a Pennsylvania-based provider of
construction services to cable television multiple system operators. In April
1998, we acquired CCI, a Georgia-based firm that provides construction services
to cable television multiple system operators, and ITI, a Missouri-based firm
that provides construction and engineering services to local and long distance
telephone companies. Each of these acquisitions was accounted for as a pooling
of interests. These transactions have diversified our telephone company customer
base to include a broader mix of work for cable television multiple system
operators. The acquisition of CCG also created a greater geographic presence for
us in the Mid-Atlantic, Midwest and Northeast regions of the United States,
while the acquisitions of CCI and ITI have further expanded our operations in
the Midwest, Upper Midwest, Rocky Mountain and West Coast regions of the United
States.
 
     In February 1999, we acquired Locating, a Washington state-based company,
for $10.0 million. Locating provides underground utility locating services used
to map and mark utilities for cable television providers, multiple system
operators, telephone companies and electrical and gas utilities. Our acquisition
of Locating expands our presence in the underground utility locating services
industry and our geographic presence in the West Coast region of the United
States.
 
     On March 31, 1999, we completed the acquisitions of ECC, a Kentucky-based
company that builds and installs new cable television systems and provides
repair and expansion services to cable television systems in several states, and
Apex, also a Kentucky-based company, which installs direct broadcast satellite
systems and provides cable sales and repair services in several Midwestern
states, for an aggregate purchase price of $21,750,000 and 774,194 shares of our
common stock. Prior to the acquisitions of ECC and Apex, the three stockholders
of ECC owned 80% of the outstanding shares of common stock of Apex. Both ECC and
Apex will operate as wholly-owned subsidiaries of Dycom.
 
     In connection with the acquisitions of CCG, CCI, ITI, Locating and ECC we
entered into five year employment contracts with certain executive officers and
selling stockholders of each of the acquired companies.

INDUSTRY OVERVIEW
 
     The telecommunications industry is undergoing rapid change. Deregulation,
competitive deployment of networks and growth in consumer demand for enhanced
telecommunications services create the need for the construction of additional
telecommunications infrastructure for new and existing providers. As a result of
this increased need for upgraded and expanded telecommunications infrastructure
and the focus on reducing costs, telecommunications providers have been
outsourcing and are expected to continue to outsource their telecommunications
infrastructure engineering, construction and maintenance requirements.
 
     Deregulation.  The Telecom Act, enacted on February 8, 1996, substantially
revised the Federal Communications Act of 1934. It established a dual
federal-state regulatory framework for eliminating certain barriers to
competition faced by competitors of incumbent local exchange carriers. Among
other things, it preempts state and local government control over access to the
telecommunications market and opens such market to new entrants. The elimination
of entry barriers will lead to increased construction of competing
telecommunications networks as competitive telecommunications providers,
existing as well as new, expand into new markets and offer services that once
were reserved for incumbents. The competition generated by the Telecom Act is
expected to continue to spur existing service providers to expand and improve
their existing facilities.
 
     While the Telecom Act significantly removed barriers to competition, many
state regulatory commissions have modified regulation of telecommunications
providers. Historically, telecommunications providers were limited by state
regulations to earning a predetermined return on capital investments. Since
1994, most of the states have repealed such regulations, substituting
regulations which limit the price telecommunications providers may charge
consumers, while eliminating the caps on the profits they may earn. These new
state regulatory frameworks eliminate profit guarantees for telecommunications
providers, while offering the potential for enhanced profitability. The combined
effect of increased competition and the prospects for greater profitability will
lead new and existing telecommunications providers to become increasingly
efficient in constructing and maintaining telecommunications infrastructure.
 
     Competitive Deployment of Networks.  Telecommunications providers and cable
television multiple system operators are actively expanding networks to provide
their customers with a combined offering of voice, video and data communications
services. Additionally, electric utilities are currently using fiber optic
technology to develop and maintain demand monitoring systems. These systems can
be used as a means of controlling the need to build additional generation
capacity and also provide electric utilities opportunities to market excess
communications capacity to telecommunications providers. Once built, these
systems will require continuous maintenance and periodic upgrading. Such
additional telecommunications infrastructure will also permit long distance
carriers and content providers to connect customers without the need to pay
exchange access fees to their competitors, local exchange carriers or cable
companies.
 
     Growth in Consumer Demand.  Increasing consumer demand is also spurring
growth in the telecommunications industry. Not only has the amount of
traditional telephone voice traffic increased, but the growth of personal
computers and modems has created significant data traffic from a wide variety of
sources. For example, businesses with multiple locations increasingly require
geographically dispersed local area networks to be linked in sophisticated wide
area networks handling large volumes of telecommunications traffic. In addition,
the Internet has expanded beyond its traditional data transmission and
file-sharing functions to offer e-mail, new data sources, commercial services,
transaction processing, independent bulletin boards, the World Wide Web and
voice transmission. To handle the growing volume of communications traffic and
to provide faster and higher quality transmission, telecommunications providers
will be required to upgrade and expand their telecommunications networks and
related infrastructure.
 
     Consumer demand for services provided over fiber optic cable has resulted
in a demand for broader bandwidth. Limited by the size of the cable or other
facilities through which communications flow, bandwidth controls both the speed
and breadth of voice, video and data communications. Because of the physical
limitations of the existing network facilities, there is an immediate need to
upgrade facilities with new and innovative technology, expanding and, in many
cases, replacing existing telecommunications
 
                                       26
<PAGE>   29
 
infrastructure to allow for increased bandwidth and the resultant faster and
greater volume of communications flow.
 
     Even local governments are increasingly becoming directly involved in
telecommunications network construction because of the perception that
telecommunications infrastructure is essential to economic growth. Local
governments spur increased demand for cable television construction services by
imposing requirements for improved services as a precondition to renewal of
franchises. Additionally, in some cases, local governments view the construction
of such infrastructure as an appropriate governmental response to private
enterprises' failure to act in a timely manner, and the cost of expanding and
upgrading telecommunications infrastructure is appearing more frequently in
governmental budgets.
 
     Increased Outsourcing.  The need to upgrade and expand telecommunications
infrastructure as a result of deregulation, competitive deployment of networks
and the growth in consumer demand for enhanced telecommunications services is
expected to continue to stimulate telecommunications providers to increase the
current level of outsourcing to independent contractors who serve the industry.
The outsourcing trend has largely been driven by the efforts of
telecommunications providers to reduce costs and to focus on their core
competencies. Independent contractors, such as us, typically have lower cost
structures than the telecommunications providers, primarily as a result of the
independent contractors' lower direct and overhead cost structures. In addition,
we believe that telecommunications providers are seeking comprehensive solutions
to their infrastructure needs by utilizing fewer qualified contractors to
provide a full range of telecommunications infrastructure services.
 
     Participant Consolidation.  Historically, our industry has been highly
fragmented. Although industry annual revenues are estimated to be several
billions of dollars, few of these companies are publicly traded. Most companies
in our industry are small, privately-held companies with annual revenues of less
than $100 million. While the industry has attracted some participation in the
past from pipeline and power plant construction firms, to date these firms have
not significantly impacted the industry.
 
     In response to the newly deregulated operating environment, the industry
has experienced some increase in business combinations among the smaller private
firms. The resulting combinations, for the most part, however, may be unable,
due to resource constraints, to adequately meet the standards demanded by
telecommunications providers seeking to outsource their telecommunications
infrastructure services function. Going forward, service firms will need
significant management expertise, technical capabilities and capital resources
to provide the level of service necessary to gain significant market share. As a
result, we believe that the industry will experience consolidation in the future
and that strategic acquisition opportunities will continue to become available.
 
THE DYCOM SOLUTION
 
     We provide a comprehensive solution to telecommunications providers
throughout the United States who need to deploy large and complex
telecommunications infrastructure quickly and with a high level of quality. Our
ability to serve a wide and diverse geographic area and our demonstrated
expertise in engineering and construction project management give us a distinct
competitive advantage in obtaining customer service contracts. As
telecommunications providers begin to offer new and expanded services on a
global basis, the time to market for these services is a critical factor in
their success. We are able to rapidly mobilize our capital equipment, financial
assets and personnel resources to effectively respond to the increasing scale
and time constraints of customer demands. In addition, we have recently begun to
offer our customers integrated engineering, procurement, construction and
maintenance services on large-scale turnkey projects, which we believe
distinguishes us from many of our competitors. We have offered our
telecommunications engineering, construction and maintenance services solution
on a national basis to local and long distance communications carriers,
competitive access providers, cable television multiple system operators and
electric utilities since 1984.
 
                                       27

BUSINESS STRATEGY
 
     Our objective is to be a leading high quality and cost effective provider
of engineering, construction and maintenance services to the telecommunications
industry. To meet this objective, we have identified the following key business
strategies:
 
     Leverage Expertise and Leadership Position.  We believe that in this highly
fragmented industry, our technical expertise and reputation should give us a
competitive advantage in securing new business from our current customers, as
well as from new customers. We believe that our reputation for quality and
reliability, operating efficiency, financial and personnel resources, and
technical expertise (e.g., ability to serve a wide geographic area and ability
to provide customers with a comprehensive solution) provide us with a
competitive advantage in bidding for and winning new contracts. We intend to
pursue the larger, more technically complex telecommunications infrastructure
projects where our technical expertise and reputation should have a greater
impact. In addition, we believe that our ability to provide integrated
engineering, procurement, construction and maintenance services on large-scale
turnkey projects distinguishes us from many of our competitors.
 
     Effectively Utilize Decentralized Management.  In order to enhance customer
service, we maintain a focused, decentralized management structure. Our holding
company structure emphasizes the importance of local subsidiary-based management
teams, which are granted significant operating flexibility in running their
business. We believe that this decentralized operating structure enables
management to make decisions and mobilize resources more quickly based on
knowledge of the local markets and the specific needs of their customers. We
complement the decentralized operating structure by sharing operating
information among our subsidiaries.
 
     Reduce Operating Costs and Increase Productivity.  We believe that the cost
savings in centralizing administrative tasks, such as insurance, asset
management, and information technology through our holding company structure,
combined with decentralized operating management, enables us to be a more cost-
effective provider of telecommunications engineering, construction and
maintenance services. As a service provider, the productivity of our own work
force and the work of our subcontractors has the single largest impact on our
cost structure. High quality, decentralized management assists us in maintaining
quality performance from our work force, as well as managing our costs. In order
to respond to peak demands for our services and to control labor expenses, we
also redeploy manpower among our subsidiaries.
 
     Refine and Enhance Formal Estimating Process.  We utilize proprietary
software to collect, maintain and statistically analyze extensive amounts of
historical cost and pricing information. Our operating subsidiaries collect
detailed cost and pricing information on a state by state, customer by customer
and job by job basis. We use this data and analysis as part of a formal
estimating process when reviewing new business opportunities. We believe that,
as a result of this process, we are able to price jobs more accurately and more
effectively allocate our resources. We will continually seek to enhance the
effectiveness of our proprietary software system by expanding the amount of
information that we gather and improving our analysis of the data.
 
GROWTH STRATEGY
 
     As a result of the increased demand for telecommunications engineering,
construction and maintenance services, greater emphasis on outsourcing of such
services by telecommunications providers, and the fragmented nature of the
industry, we believe there are significant opportunities to expand our business
internally and through acquisitions.
 
     Internal Growth.  We are focused on generating internal growth by: (i)
increasing the volume of services to existing customers; (ii) expanding the
scope of services to existing customers; (iii) broadening our customer base; and
(iv) geographically expanding our service area. We are also seeking to reduce
operating expenses and improve operating margins by centralizing costs such as
insurance administration, asset management and information technology, thereby
eliminating redundancies at the subsidiary level. Additionally, the competitive
pressures of deregulation have prompted several existing customers to
 
                                       28
<PAGE>   31
 
increase the outsourcing of noncore activities, which can provide opportunities
for enhancing internal growth without necessarily requiring us to achieve market
share gains.
 
     Growth Through Acquisitions.  As part of our growth strategy, we intend to
capitalize on the current opportunity to make strategic acquisitions of
engineering, construction and maintenance services companies serving the
telecommunications industry throughout the United States. We continually review
and evaluate potential acquisition candidates and believe that as competition
intensifies, smaller companies will seek to consolidate with companies such as
us. We target acquisitions that provide complementary services in existing
markets that we serve or allow expansion into new geographic areas. For our
acquisition targets, our key criteria are profitability in excess of industry
standards, stable and growing customer base, proven operational and technical
competence, and experienced management that fits within our decentralized
operating structure. Further, we seek the opportunity to realize cost savings by
eliminating redundant costs and achieving economies of scale in certain items
such as insurance, information technologies and administrative functions. We
believe that we can attain significant revenue and earnings growth through
acquisitions; however, there can be no assurance that we will be able to acquire
and integrate such businesses successfully or that such acquisitions will have a
positive effect on our operating results.
 
     We believe that a variety of attractive consolidation opportunities exist
within the currently fragmented telecommunications engineering, construction and
maintenance services industry and, while we are not currently a party to any
agreements, understanding or arrangements regarding any material acquisitions,
we are currently evaluating a number of potential acquisition prospects. We
believe that additional acquisition opportunities may be available to implement
our acquisition strategy upon completion of this offering.
 
SERVICES
 
  Telecommunications Services
 
     Engineering.  We provide outside plant engineers and drafters to local
exchange carriers and competitive access providers. We design aerial, buried and
underground fiber optic and copper cable systems from the telephone central
office to the ultimate consumer's home or business. Engineering services for
local exchange carriers include the design of service area concept boxes,
terminals, buried and aerial drops, transmission and central office equipment
design and the proper administration of feeder and distribution cable pairs. For
competitive access providers, we design building entrance laterals, fiber rings
and conduit systems. We obtain rights of way and permits in support of
engineering activities, and provide construction management and inspection
personnel in conjunction with engineering services or on a stand alone basis.
For cable television multiple system operators, we perform make ready studies,
strand mapping, field walk out, computer-aided radio frequency design and
drafting, and fiber cable routing and design.
 
     Construction and Maintenance.  The services we provide include the placing
and splicing of cable, excavation of trenches in which to place the cable,
placement of related structures such as poles, anchors, conduits, manholes,
cabinets and closures, placement of drop lines from the main distribution lines
to the customer's home or business, and maintenance and removal of these
facilities. In addition, we install and maintain transmission and central office
equipment. We have the capacity to directionally bore the placement of cables, a
highly specialized and increasingly necessary method of placing buried cable
networks in congested urban and suburban markets where trenching is highly
impractical. With our acquisition of Apex, we provide installation and
maintenance services of direct broadcast satellite systems.
 
     Premise Wiring.  We also provide premise wiring services to a variety of
large corporations and certain governmental agencies. These services, unlike the
engineering, construction and maintenance services provided under various master
service agreements and to cable television multiple system operators, are
limited to the installation, repair and maintenance of telecommunications
infrastructure within improved structures. Projects include the placement and
removal of various types of cable within buildings and individual offices. These
services generally include the development of communication networks within a

of computer operations, telephone systems, Internet access and communications
monitoring systems established for purposes of monitoring environmental controls
or security procedures.
 
  Underground Utility Locating Services
 
     We are a provider of underground utility locating services, primarily to
telecommunications providers. Under a variety of state laws, excavators are
required to locate underground utilities prior to excavating. Utilities located
include telephone, cable television, power and gas. Recently, excavators
performing telecommunications network upgrades and expansions have generated
significant growth in requests for underground utility locating, and we expect
this trend to continue. We are currently a party to 32 underground utility
locating contracts. We offer these services throughout the United States.
 
  Electrical Construction and Maintenance Services
 
     We perform electrical construction and maintenance services for electric
companies. This construction is performed primarily as a stand alone service,
although at times it is performed in conjunction with services for
telecommunications providers. These services include installing and maintaining
electrical transmission and distribution lines, setting utility poles and
stringing electrical lines, principally above ground. The work performed often
involves high voltage splicing and, on occasion, the installation of underground
high voltage distribution systems. We also provide the repair and replacement of
lines which are damaged or destroyed as a result of weather conditions.
 
  Revenues by Service Group
 
     For the fiscal years ended July 31, 1996, 1997 and 1998 and the six-month
periods ended January 31, 1998 and 1999, the percentages of our total contract
revenues earned were derived from telecommunications services, underground
utility locating services and electrical construction and maintenance services
as set forth below.

CUSTOMER RELATIONSHIPS
 
     Our current customers include local exchange carriers such as BellSouth
Telecommunications, Inc., SBC Communications, Inc., U.S. West Communications,
Inc., Sprint Corporation, Ameritech Corporation, GTE Corporation, The Southern
New England Telephone Company, Citizen Utilities and Cincinnati Bell Telephone.
We also currently provide telecommunications engineering, construction and
maintenance services to a number of cable television multiple system operators
including Comcast Cable Communications Inc., Cablevision, Inc., Falcon Cable
Media, Time Warner, Inc. and MediaOne, Inc. We also provide our services to long
distance carriers such as MCI Telecommunications Corporation and AT&T
Corporation, as well as to competitive access providers such as MFS
Communications Company, Inc. Premise wiring services have been provided to,
among others, Lucent Technologies, Inc., Duke University, International Business
Machines Corporation, and several state governments. The Company also provides
construction and maintenance support to Lee County Electrical Cooperative,
Florida Power and Light Company, and Florida Power Corporation.
 
     While our customer base has broadened in recent years, our customer base
remains highly concentrated, with our top five customers in fiscal years 1996,
1997 and 1998 and the first six months of
 
                                       30
<PAGE>   33
 
fiscal year 1999 accounting in the aggregate for approximately 68%, 63%, 65% and
63%, respectively, of our contract revenues. During fiscal 1998 and the
six-month period ended January 31, 1999, approximately 22% and 23%,
respectively, of our contract revenues were derived from BellSouth
Telecommunications, Inc., 24% and 21%, respectively, from Comcast Cable
Communications, Inc. and 7% and 5%, respectively, from GTE Corporation. We
believe that a substantial portion of our contract revenues and operating income
will continue to be derived from a concentrated group of customers. The loss of
any of such customers could have a material adverse effect on our business,
financial condition and results of operations.
 
     A significant amount of our business is performed under master service
agreements. These agreements with telecommunications providers are generally
exclusive requirement contracts, with certain exceptions, including the
customer's option to perform the services with its own regularly employed
personnel. The agreements are typically three to five years in duration,
although the terms typically permit the customer to terminate the agreement upon
90 days' prior written notice. Each agreement contemplates hundreds of
individual construction and maintenance projects valued generally at less than
$10,000 each. We bid on other jobs on a nonrecurring basis.
 
     Although historically master service agreements have been awarded through a
competitive bidding process, recent trends have been toward securing or
extending such contracts on negotiated terms. With the rapid expansion of the
telecommunications market and the immediate need for upgrading existing, as well
as constructing new, telecommunications infrastructure, we believe that more
master service agreements will be awarded on the basis of negotiated terms as
opposed to the competitive bidding process.
 
     Our sales and marketing efforts are primarily the responsibility of the
management of our operating subsidiaries.
 
BACKLOG
 
     We view our backlog to be comprised of the uncompleted portion of services
to be performed under job-specific contracts and the estimated value of future
services that we expect to provide under long-term requirements contracts. Our
backlog at January 31, 1999 was $728.6 million. We expect to complete
approximately 45% of this backlog during the next twelve months. Due to the
nature of our contractual commitments, in many instances our customers are not
committed to specific volumes of services to be purchased under a contract, but
rather we are committed to perform these services if requested by the customer.
However, the customer is obligated to obtain these services from us if they are
not performed by the customer internally. Many of the contracts are multi-year
agreements, and we include in our backlog the full amount of services projected
to be performed over the life of the contract based on our historical
relationships with our customers and experience in procurements of this nature.
Historically, we have not experienced a material variance between the amount of
services we expect to perform under a contract and the amount actually performed
for a specified period. There can be no assurance, however, as to the customer's
requirements during a particular period or that such estimates at any point in
time are accurate.
 
SAFETY AND RISK MANAGEMENT
 
     We are committed to ensuring that our employees perform their work in the
safest possible manner. We regularly communicate with our employees to promote
safety and to instill safe work habits. Our risk manager, a holding company
employee, reviews all accidents and claims throughout the operating
subsidiaries, examines trends and implements changes in procedures or
communications to address any safety issues.
 
     The primary claims arising in our business are workers' compensation and
other personal injuries, various general liabilities, and vehicle liability
(personal injury and property damage). We are self-insured for automobile
liability up to $250,000, for general liability up to $250,000, and for workers'
compensation, in states where we elect to do so, up to $500,000 per occurrence
and $10.5 million annual aggregate. We have umbrella coverage up to a policy
limit of $51.0 million.
                                       31
<PAGE>   34
 
     We carefully monitor claims and participate actively in claims estimates
and adjustments. The estimated costs of self-insured claims, which include
estimates for incurred but not reported claims, are accrued as liabilities on
our balance sheet. Due to changes in our loss experience in recent years,
insurance accruals have varied from year to year and have had an effect on
operating margins. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and Note 1 of the Notes to Consolidated
Financial Statements.
 
COMPETITION
 
     The telecommunications engineering, construction and maintenance services
industry in which we operate is highly competitive, requiring substantial
resources and skilled and experienced personnel. We compete with other
independent contractors in most of the markets in which we operate, several of
which are large domestic companies that have greater financial, technical and
marketing resources than us. In addition, there are relatively few, if any,
barriers to entry into the markets in which we operate and, as a result, any
organization that has adequate financial resources and access to technical
expertise may become a competitor to us. A significant portion of our revenues
are currently derived from master service agreements and price is often an
important factor in the award of such agreements. Accordingly, we could be
outbid by our competitors in an effort to procure such business. There can be no
assurance that our competitors will not develop the expertise, experience and
resources to provide services that are equal or superior in both price and
quality to our services, or that we will be able to maintain or enhance our
competitive position. We may also face competition from the in-house service
organizations of our existing or prospective customers, including
telecommunications providers, which employ personnel who perform some of the
same types of services as those provided by us. Although a significant portion
of these services is currently outsourced, there can be no assurance that our
existing or prospective customers will continue to outsource telecommunications
engineering, construction and maintenance services in the future.
 
     We believe that the principal competitive factors in the market for
telecommunications engineering, construction and maintenance services include
technical expertise, reputation, price, quality of service, availability of
skilled technical personnel, geographic presence, breadth of service offerings,
adherence to industry standards and financial stability. We believe that we
compete favorably with our competitors on the basis of these competitive
factors.
 
EMPLOYEES
 
     As of March 31, 1999, we employed 5,205 persons. Our workforce is primarily
non-unionized. We have never experienced a work stoppage or strike. The number
of employees of Dycom and our subsidiaries varies according to the work in
progress. As a matter of course, we maintain a nucleus of technical and
managerial personnel from which we draw to supervise all projects. We add
additional employees as needed to complete specific projects. We believe that
our employee relations are good.
 
MATERIALS
 
     In many cases, our customers supply most or all of the materials required
for a particular contract and we provide the personnel, tools and equipment to
perform the installation services. However, with respect to certain of our
contracts, we may supply part or all of the materials required. In these
instances, we are not dependent upon any one source for the products which we
customarily utilize to complete the job. We are not presently experiencing, not
do we anticipate experiencing, any difficulties in procuring an adequate supply
of materials.
 
FACILITIES
 
     We lease our executive offices in Palm Beach Gardens, Florida. Our
subsidiaries operate from owned or leased administrative offices, district field
offices, equipment yards, shop facilities and temporary storage locations. We
own facilities in Phoenix, Arizona; Durham, North Carolina; Pinellas Park,
Florida; Sturgis, Kentucky; and West Palm Beach, Florida. We also lease,
pursuant to long-term noncancellable leases,
 
                                       32
<PAGE>   35
 
facilities in West Chester, Pennsylvania; Kimberling City, Missouri; Lithonia,
Georgia; Knoxville, Tennessee; Issaquah, Washington; and Greensboro, North
Carolina. We also lease and own other smaller properties as necessary to enable
us to efficiently perform our obligations under master service agreements and
other specific contracts. We believe that our facilities are adequate for our
current operations.
 
LEGAL PROCEEDINGS
 
     In September 1995, the State of New York commenced a sales and use tax
audit of CCG for the years 1989 through 1995. As a result of the audit, certain
additional taxes were paid by CCG in fiscal 1996. In addition, the State of New
York concluded that cable television service providers are subject to New York
State sales taxes for the construction of cable television distribution systems,
and by a Notice dated January 1997, asserted amounts due from CCG for sales
taxes and interest for the periods through August 31, 1995, aggregating
approximately $1.3 million. Any sales taxes asserted against us may be offset by
use taxes already paid by our customers. We intend to vigorously contest the
assertion. We are unable to assess the likelihood of any particular outcome at
this time or to quantify the effect a resolution of this matter may have on our
consolidated financial statements. See Note 17 of the Notes to Consolidated
Financial Statements.
 
     In the normal course of business, certain of our subsidiaries have other
pending and unasserted claims. Although the ultimate resolution and liability of
these claims cannot be determined, management believes the final disposition of
these claims will not have a material adverse impact on Dycom's consolidated
financial condition or results of operations.

                          DESCRIPTION OF CAPITAL STOCK
 
     We have authorized the issuance of 50,000,000 shares of common stock,
$0.33 1/3 par value per share, and 1,000,000 shares of preferred stock, $1.00
par value per share.
 
COMMON STOCK
 
     On April 27, 1999, there were 23,046,063 outstanding shares of common stock
held by 640 stockholders of record.
 
     The holders of common stock are entitled to one vote per share on all
matters submitted to a vote of the stockholders. Holders of common stock do not
have cumulative voting rights. Therefore, holders of more than 50% of the shares
of common stock are able to elect all our directors eligible for election in a
given year. The holders of common stock are entitled to dividends and other
distributions out of assets legally available if and when declared by the board
of directors. Upon our liquidation, dissolution or winding up, the holders of
common stock are entitled to share pro rata in the distribution of all of our
assets remaining available for distribution after satisfaction of all
liabilities, including any prior rights of any preferred stock which may be
outstanding. There are no redemption or sinking fund provisions applicable to
the common stock.
 
     The transfer agent and registrar for the common stock is First Union
National Bank of North Carolina, Charlotte, North Carolina.
 
PREFERRED STOCK
 
     There are no shares of preferred stock outstanding. Series of the preferred
stock may be created and issued from time to time by our board of directors,
with such rights and preferences as they may determine.
 
ANTI-TAKEOVER PROVISIONS
 
     On June 1, 1992, we approved a shareholder rights plan. All stockholders of
record on June 15, 1992 were issued a right (a "Right") for each outstanding
share of our common stock. Common stock issued after the record date but prior
to the Separation Time (as defined in the shareholder rights plan) will also
receive one Right. Each Right entitles the holder to purchase one-half share of
common stock for an exercise price of $12.00, subject to certain adjustments.
The Right is exercisable only when a triggering event occurs. Among the
triggering events are (1) a person or group's acquisition of 20% or more of our
common stock, (2) the commencement of a tender offer which would result in a
person or group owning 20% or more of our common stock, or (3) the acquisition
of at least 10% of our common stock and such acquisition is determined to have
effects adverse to us. We can redeem the Rights at $0.01 per Right, subject to
certain adjustments, at any time prior to ten days after a triggering event
occurs. The Rights will expire on the earlier of certain events set forth in the
shareholder rights plan and June 1, 2002. While the Rights will not prevent a
takeover of Dycom, they have certain anti-takeover effects by causing
substantial dilution to an acquiring party when a triggering event occurs, to
the extent that the board of directors has not previously redeemed the Rights.
 
     We have agreements with certain of our executive officers which provide for
substantial compensation (in general terms, double the officer's salary and
bonuses paid the previous year), upon a change of control in our company. Thomas
R. Pledger's employment agreement also permits him to terminate his employment
in the event of a change of control. The current total amount of payments under
these agreements upon a change in control would be approximately $4.5 million.
Such payments would be triggered by any person's acquisition of more than fifty
percent of our outstanding securities, the sale or transfer of substantially all
of our assets to someone other than one of our wholly-owned subsidiaries, or a
change of control of the board of directors.
 
     Our articles of incorporation provide that the board of directors is
divided into three classes, as nearly equal in number as possible, with one
class of directors being elected each year for a three-year term. The
                                       37
<PAGE>   40
 
classification of the board may have the effect of delaying a change in a
majority of the members of our board of directors.
 
     Our articles of incorporation require approval of 80% of the outstanding
shares of our capital stock entitled to vote in elections of directors for any
merger with or into another corporation or any sale or transfer of all or a
substantial part of our assets to, or any sale or transfer to us or any
subsidiary in exchange for our securities or any assets (except assets valued at
less than $1,000,000) of, any other corporation or person, if at the time such
other corporation or person is the beneficial owner, or is affiliated with the
beneficial owner, of more than 20% of the outstanding shares of our capital
stock entitled to vote in elections of directors. This requirement is not
applicable to any such transaction with another corporation which was approved
by our board of directors prior to the time that such other corporation became a
holder of more than 20% of the outstanding shares of our capital stock.
 
     The Florida Business Corporation Act contains provisions eliminating the
voting rights of "control shares," which are defined as shares which give any
person, directly or indirectly, ownership of, or the power to direct the
exercise of voting power with respect to, 20% or more of the outstanding voting
power of an "issuing public corporation." A corporation is an issuing public
corporation if it has at least 100 shareholders, its principal place of
business, principal office or substantial assets are in Florida and either more
than 10% of its shareholders reside in Florida, more than 10% of its shares are
owned by Florida residents or 1,000 shareholders reside in Florida. The voting
rights of control shares are not eliminated if the articles of incorporation or
the bylaws of the corporation prior to the acquisition provide that the statute
does not apply. Voting rights are restored to control shares if, subsequent to
their acquisition, the corporation's shareholders (other than the holder of
control shares, officers of the corporation and employee directors) vote to
restore such voting rights.
 
     The Florida Business Corporation Act also restricts "affiliated
transactions" (mergers, consolidations, transfers of assets and other
transactions) between "interested shareholders" (the beneficial owners of 10% or
more of the corporation's outstanding shares) and the corporation or any
subsidiary. Affiliated transactions must be approved by two-thirds of the voting
shares not beneficially owned by the interested shareholder or by a majority of
the corporation's "disinterested" directors. The statutory restrictions do not
apply if the corporation has had fewer than 300 shareholders of record for three
years, the interested shareholder has owned at least 80% of the outstanding
shares for five years, the interested shareholder owns at least 90% of the
corporation's outstanding voting shares, or certain consideration is paid to all
shareholders.
 
     The provisions of our articles and by-laws, the existence of the
shareholder rights plan and the change of control agreements and the application
of the anti-takeover provisions of the Florida Business Corporation Act could
have the effect of discouraging, delaying or preventing a change of control not
approved by the board of directors which could affect the market price of our
common stock.
 
INDEMNIFICATION
 
     Our by-laws require us to indemnify each of our directors and officers to
the fullest extent permitted by law and limits the liability of our directors
and stockholders for monetary damages in certain circumstances.
 
     The provisions of the Florida Business Corporation Act that allow such
indemnification do not eliminate the duty of care of a director and, in
appropriate circumstances, equitable remedies such as injunctive or other forms
of nonmonetary relief will remain available. In addition, each director
continues to be subject to liability for (a) criminal violations, unless the
director had reasonable cause to believe his conduct was lawful or had no
reasonable cause to believe his conduct was unlawful, (b) deriving an improper
personal benefit from a transaction, (c) voting for or assenting to an unlawful
distribution, and (d) willful misconduct or a conscious disregard for our best
interests in a proceeding by or on our behalf or in a proceeding by or on behalf
of a stockholder. The statute does not affect a director's responsibilities
under any other law, such as the federal securities laws or state or federal
environmental laws.

DIVIDEND RESTRICTIONS
 
     Our credit agreement currently limits our ability to pay dividends on the
common stock to 50% of net income for the fiscal year. The credit agreement's
restrictions on our debt-to-net worth, quick and current ratios also affect our
ability to pay dividends. The payment of dividends on the common stock is also
subject to the preference that may be applicable to any then outstanding
preferred stock.

the Underwriters, Dycom and the selling stockholders (the "Underwriting
Agreement"), to purchase from Dycom and the selling stockholders the number of
shares of common stock indicated below opposite their respective names at the
public offering price less the discounts and commissions to underwriters set
forth on the cover page of this prospectus and in the table below. The
Underwriting Agreement provides that the obligations of the Underwriters are
subject to certain conditions precedent, and that the Underwriters are committed
to purchase all of such shares if any are purchased.

</TABLE>
 
     The Underwriters have advised Dycom and the selling stockholders that the
Underwriters propose initially to offer the common stock to the public on the
terms set forth on the cover page of this prospectus. The Underwriters may allow
to selected dealers a concession of not more than $1.37 per share, and the
Underwriters may allow, and such dealers may reallow, a concession of not more
than $0.10 per share to certain other dealers. After the offering, the offering
price and other selling terms may be changed by the Underwriters. The common
stock is offered subject to receipt and acceptance by the Underwriters, and to
certain other conditions, including the right to reject an order in whole or in
part. The Underwriters may offer the shares of common stock through a selling
group.
 
     Dycom and the selling stockholders have granted an option to the
Underwriters, exercisable during the 30-day period after the date of this
prospectus, to purchase up to a maximum of 375,000 and 30,000 additional shares
of common stock, respectively, to cover over-allotments, if any, at the same
price as the initial 2,700,000 shares to be purchased by the Underwriters. To
the extent that the Underwriters exercise this option, each of the Underwriters
will be committed, subject to certain conditions, to purchase such additional
shares in approximately the same proportion as set forth in the table above. The
Underwriters may purchase such shares only to cover over-allotments made in
connection with the offering.
 
     The following table summarizes the compensation to be paid to the
Underwriters by the Company and the selling stockholders.

     Dycom estimates that the total expenses of the offering, excluding
underwriting discounts and commissions, will be approximately $450,000.
 
     Joseph M. Schell, a director of Dycom, also serves as a consultant to
NationsBanc Montgomery Securities LLC, but not as its representative on the
board of directors. NationsBanc Montgomery Securities LLC does not have the
right to designate or nominate a member of Dycom's board of directors.
 
     The Underwriting Agreement provides that Dycom and the selling stockholders
will indemnify the Underwriters and their controlling persons against certain
liabilities, including civil liabilities under the Securities Act, or will
contribute to payments the Underwriters may be required to make in respect
thereof.

     The selling stockholders and the other directors and executive officers of
Dycom have agreed that they will not, without the prior written consent of
NationsBanc Montgomery Securities LLC (which consent may be withheld in its sole
discretion), directly or indirectly, sell, offer, contract or grant any option
to sell (including without limitation any short sale), pledge, transfer,
establish an open "put equivalent position" within the meaning of Rule 16a-1(h)
under the Exchange Act ("Rule 16a-1(h)") or otherwise dispose of any shares of
common stock owned either of record or beneficially by them, or publicly
announce the intention to do any of the foregoing, for a period commencing on
the date of this prospectus and continuing through the close of trading on the
date 90 days after such date. NationsBanc Montgomery Securities LLC, may, in its
sole discretion and at any time without notice, release all or any portion of
the securities, subject to those lock-up agreements. In addition, Dycom has
agreed that for a period of 90 days after the date of this prospectus it will
not, without the prior written consent of NationsBanc Montgomery Securities LLC
(which consent may be withheld in its sole discretion), directly or indirectly,
sell, offer, contract or grant any option to sell, pledge, transfer or establish
an open "put equivalent position" within the meaning of Rule 16a-1(h), or
otherwise dispose of or transfer, or announce the offering of, or file any
registration statement under the Securities Act in respect of, any shares of
common stock, options or warrants to acquire shares of common stock or
securities exchangeable or exercisable for or convertible into shares of common
stock, subject to certain limited exceptions including granting of options and
sales of shares under Dycom's existing option plans.
 
     Until the distribution of the common stock is completed, rules of the
Securities and Exchange Commission may limit the ability of the Underwriters to
bid for and purchase the common stock. As an exception to these rules, the
Underwriters are permitted to engage in certain transactions that stabilize the
price of the common stock. The Underwriters have advised Dycom that such
transactions may be effected on the New York Stock Exchange or otherwise. Such
transactions consist of bids or purchases for the purpose of pegging, fixing or
maintaining the price of the common stock. If the Underwriters create a short
position in the common stock in connection with the offering, i.e., if they sell
more shares of common stock than are set forth on the cover page of this
prospectus, the Underwriters may reduce that short position by purchasing common
stock in the open market. The Underwriters may also elect to reduce any short
position by exercising all or part of the over-allotment option described above.
The Underwriters may also impose a penalty bid on certain selling group members.
This means that if the Underwriters purchase shares of common stock in the open
market to reduce the Underwriters' short position or to stabilize the price of
the common stock, they may reclaim the amount of the selling concession from the
selling group members who sold those shares as part of the offering.
 
     In general, purchase of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of a security to the extent that it were
to discourage resales of the security. Neither Dycom nor any of the Underwriters
makes any representations or predictions as to the direction or magnitude of any
effect that the transactions described above may have on the price of the common
stock. In addition, neither Dycom nor any of the Underwriters makes any
representations that the Underwriters will engage in such transactions or that
such transactions, once commenced, will not be discontinued without notice.

                          INDEPENDENT AUDITORS' REPORT
 
Dycom Industries, Inc.:
 
     We have audited the consolidated balance sheets of Dycom Industries, Inc.
and subsidiaries (the "Company") as of July 31, 1998 and 1997, and the related
consolidated statements of operations, stockholders' equity, and cash flows for
each of the three years in the period ended July 31, 1998. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on the financial statements based on our
audits. The consolidated financial statements give retroactive effect to the
merger of Communications Construction Group, Inc., which has been accounted for
as a pooling of interests as described in Note 3 to the consolidated financial
statements. We did not audit the statements of operations, stockholders' equity,
and cash flows of Communications Construction Group, Inc. for the years ended
May 31, 1997 and 1996, which statements reflect total revenues of $67,717,326
and $50,121,009 for the years ended May 31, 1997 and 1996, respectively. Those
financial statements were audited by other auditors whose report has been
furnished to us, and our opinion, insofar as it relates to the amounts included
for Communications Construction Group, Inc. for such periods, is based solely on
the report of such other auditors. As described in Note 3 to the consolidated
financial statements, subsequent to the issuance of the report of the other
auditors, Communications Construction Group, Inc. changed its fiscal year to
conform to the fiscal year of Dycom Industries, Inc. for the period ended July
31, 1997.
 
     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 and the report of the other auditors provide a
reasonable basis for our opinion.
 
     In our opinion, based on our audits and the report of the other auditors,
the consolidated financial statements referred to above present fairly, in all
material respects, the financial position of Dycom Industries, Inc. and
subsidiaries as of July 31, 1998 and 1997, and the results of their operations
and their cash flows for each of the three years in the period ended July 31,
1998 in conformity with generally accepted accounting principles.

                    DYCOM INDUSTRIES, INC. AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Principles of Consolidation.  -- The consolidated financial statements
include Dycom Industries, Inc. ("Dycom" or the "Company") and its subsidiaries,
all of which are wholly owned. On July 29, 1997, Communications Construction
Group, Inc. ("CCG") was acquired by the Company through an exchange of common
stock. On April 6, 1998, Cable Com Inc. ("CCI") and Installation Technicians,
Inc. ("ITI") were acquired by the Company through an exchange of common stock.
These acquisitions were accounted for as poolings of interests. Accordingly, the
Company's consolidated financial statements include the results of CCG, CCI and
ITI for all periods presented. See Note 3.
 
     The Company's operations consist primarily of telecommunications,
underground utility locating and electrical construction and maintenance
services contracting. All material intercompany accounts and transactions have
been eliminated.
 
     Pro Forma Adjustments -- Prior to the acquisition by Dycom, CCI and ITI
elected under Subchapter S of the Internal Revenue Code to have the stockholders
recognize their proportionate share of CCI's and ITI's taxable income on their
personal tax return in lieu of paying corporate income tax. The pro forma net
income and earnings per common share reflected on the Statements of Operations
reflects a provision for current and deferred income taxes for all periods
presented as if the corporations were included in Dycom's federal and state
income tax returns. At April 6, 1998, the consummation date of the merger, CCI
and ITI recorded deferred taxes on the temporary differences between the
financial reporting basis and the tax basis of their assets and liabilities. The
deferred tax (asset) liability recorded by CCI and ITI was $616,358 and
$(11,035), respectively.
 
     Use of Estimates -- The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates and such differences may be material to the financial statements.
 
     Estimates are used in the Company's revenue recognition of work-in-process,
allowance for doubtful accounts, self-insured claims liability, deferred tax
asset valuation allowance, depreciation and amortization, and in the estimated
lives of assets, including intangibles.
 
     Revenue -- Income on short-term unit contracts is recognized as the related
work is completed. Work-in-process on unit contracts is based on management's
estimate of work performed but not billed. Income on long-term contracts is
recognized on the percentage-of-completion method based primarily on the ratio
of contract costs incurred to date to total estimated contract costs. At the
time a loss on a contract becomes known, the entire amount of the estimated
ultimate loss is accrued.
 
     "Costs and estimated earnings in excess of billings" represents the excess
of contract revenues recognized under the percentage-of-completion method of
accounting for long-term contracts and work-in-process on unit contracts over
billings to date. For those contracts in which billings exceed contract revenues
recognized to date, such excesses are included in the caption "billings in
excess of costs and estimated earnings".
 
     Cash and Equivalents -- Cash and equivalents include cash balances on
deposit in banks, overnight repurchase agreements, certificates of deposit,
commercial paper, and various other financial instruments having an original
maturity of three months or less. For purposes of the consolidated statements of
cash flows, the Company considers these amounts to be cash equivalents.
 
     Property and Equipment -- Property and equipment is stated at cost.
Depreciation and amortization is computed over the estimated useful life of the
assets utilizing the straight-line method. The estimated useful service lives of
the assets are: buildings -- 20-31 years; leasehold improvements -- the term of
the respective lease or the estimated useful life of the improvements, whichever
is shorter; vehicles -- 3-

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
7 years; equipment and machinery -- 2-10 years; and furniture and
fixtures -- 3-10 years. Maintenance and repairs are expensed as incurred;
expenditures that enhance the value of the property or extend its useful life
are capitalized. When assets are sold or retired, the cost and related
accumulated depreciation are removed from the accounts and the resulting gain or
loss is included in income.
 
     Intangible Assets -- The excess of the purchase price over the fair market
value of the tangible net assets of acquired businesses (goodwill) is amortized
on a straight-line basis over 40 years. The appropriateness of the carrying
value of goodwill is reviewed periodically by the Company at the subsidiary
level. An impairment loss is recognized when the projected future cash flows is
less than the carrying value of goodwill. No impairment loss has been recognized
in the periods presented.
 
     Amortization expense was $155,088 for each of the fiscal years ended July
31, 1996, 1997, and 1998. The intangible assets are net of accumulated
amortization of $1,151,358 and $1,306,446 at July 31, 1997 and 1998,
respectively.
 
     Self-Insured Claims Liability -- The Company is primarily self-insured, up
to certain limits, for automobile and general liability, workers' compensation,
and employee group health claims. A liability for unpaid claims and the
associated claim expenses, including incurred but not reported losses, is
actuarially determined and reflected in the consolidated financial statements as
an accrued liability. The self-insured claims liability includes incurred but
not reported losses of $4,429,000 and $5,120,000 at July 31, 1997 and 1998,
respectively. The determination of such claims and expenses and the
appropriateness of the related liability is continually reviewed and updated.
 
     Income Taxes -- The Company and its subsidiaries, except for CCG, CCI and
ITI, file a consolidated federal income tax return. CCG was included in the
Company's consolidated federal income tax return effective July 29, 1997 and CCI
and ITI will be included effective April 6, 1998. Deferred income taxes are
provided for the temporary differences between the financial reporting basis and
the tax basis of the Company's assets and liabilities.
 
     Per Share Data -- Earnings per common share-basic is computed using the
weighted average common shares outstanding during the period. Earnings per
common share-diluted is computed using the weighted average common shares
outstanding during the period and the dilutive effect of common stock options,
using the treasury stock method. See Notes 2 and 14.
 
     Stock Option Plans -- In October 1995, the Financial Accounting Standards
Board ("FASB") issued Statement of Financial Accounting Standards ("SFAS") No.
123 "Accounting for Stock Based Compensation" which was effective for the
Company beginning August 1, 1996. SFAS No. 123 requires expanded disclosures of
stock based compensation arrangements with employees and encourages, but does
not require, compensation cost to be measured based on the fair value of the
equity instrument awarded. Under SFAS No. 123, companies are permitted, however,
to continue to apply Accounting Principle Board ("APB") Opinion No. 25, which
recognizes compensation cost based on the intrinsic value of the equity
instrument awarded. The Company will continue to apply APB Opinion No. 25 to its
stock based compensation awards to employees and will disclose in the annual
financial statements the required pro forma effect on net income and earnings
per share. See Note 14.
 
     Recently Issued Accounting Pronouncements -- In June 1997, the FASB issued
SFAS No. 130 "Reporting Comprehensive Income" which establishes standards for
reporting and display of comprehensive income and its components (revenues,
expenses, gains and losses) in a full set of general-purpose financial
statements. This statement requires that an enterprise classify items of other
comprehensive income by their nature in a financial statement and display the
accumulated balance of other comprehensive income separately from retained
earnings and additional paid-in capital in the equity section of a statement of
financial position. This statement is effective for fiscal years beginning after
December 15, 1997.

                    DYCOM INDUSTRIES, INC. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     In June 1997, the FASB issued SFAS No. 131 "Disclosure about Segments of an
Enterprise and Related Information" which establishes standards for public
business enterprises to report information about operating segments in annual
financial statements and requires those enterprises to report selected
information about operating segments in annual financial reports issued to
shareholders. It also establishes the standards for related disclosures about
products and services, geographic areas, and major customers. This statement
requires that a public business enterprise report financial and descriptive
information about its reportable operating segments. The financial information
is required to be reported on the basis that it is used internally for
evaluating segment performance and deciding how to allocate resources to
segments. Operating segments are components of an enterprise about which
separate financial information is available that is evaluated regularly by the
chief operating decision maker in deciding how to allocate resources and in
assessing performance. This statement is effective for financial statements for
periods beginning after December 15, 1997.
 
     In February 1998, the FASB issued SFAS No. 132 "Employers' Disclosures
about Pension and Other Postretirement Benefits" which revises certain
disclosures about pension and other postretirement benefit plans. This statement
does not change the measurement and recognition methods for pension or
postretirement benefit costs reported in financial statements. This statement is
effective for fiscal years beginning after December 15, 1997.
 
     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" which establishes standards for the
accounting and reporting of derivative instruments, including certain derivative
instruments embedded in other contracts, (collectively referred to as
derivatives) and for hedging activities. It requires that an entity recognize
all derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. This statement is
effective for financial statements for periods beginning after December 15,
1999.
 
     Management is currently evaluating the requirements and related disclosures
of SFAS No. 130, 131, 132, and 133.
 
2.  ACCOUNTING CHANGE
 
     In February 1997, the FASB issued SFAS No. 128 "Earnings per Share" which
changes the method of calculating earnings per share and was effective for the
Company in the quarter ended January 31, 1998. All periods presented have been
restated in accordance with the provisions of SFAS No. 128.

3.  ACQUISITIONS
 
     On July 29, 1997, the Company consummated the CCG acquisition. The Company
issued 3,079,863 shares of common stock in exchange for all the outstanding
capital stock of CCG. Dycom has accounted for the acquisition as a pooling of
interests and, accordingly, the Company's historical financial statements
include the results of CCG for all periods presented.
 
     Prior to the acquisition, CCG used a fiscal year ending May 31 and as of
July 31, 1997 adopted Dycom's fiscal year. The Company's consolidated statements
of operations for fiscal years ended July 31, 1996, and 1997 combines the
statements of operations of CCG for its fiscal years ended May 31, 1996, and
1997, respectively. The total revenue and net income of CCG for the two-month
period ended July 31, 1997 were $13.1 million and $0.4 million, respectively,
with the net income reflected as an adjustment to retained earnings as of July
31, 1997.
 
     On April 6, 1998, the Company acquired CCI and ITI and issued 1.8 million
and 900,000 shares of common stock in exchange for all the outstanding capital
stock of CCI and ITI, respectively. Dycom has accounted for the acquisitions as
poolings of interests and, accordingly, the Company's historical financial
statements include the results of CCI and ITI for all periods presented.
 
     Prior to the acquisitions, CCI and ITI used a fiscal calendar year
consisting of a 52/53 week time period and, as a result of the merger, have
adopted Dycom's fiscal year end of July 31. All periods presented reflect the
adoption of such fiscal year end as of the beginning of the period. The combined
and separate company results of Dycom, CCG, CCI and ITI for the fiscal years

     On April 29, 1998, the Company signed an amendment to its current bank
credit agreement, increasing the total facility to $85.0 million. The amended
bank credit agreement provides for (i) a $30.0 million revolving working capital
facility; (ii) a $15.0 million standby letter of credit facility; (iii) a $25.0
million revolving equipment acquisition and small business purchase facility;
and (iv) a $15.0 million five-year term loan. The revolving working capital
facility, the standby letter of credit facility and the revolving equipment
facility are available for a two-year period.
 
     The revolving working capital facility bears interest, at the option of the
Company, at the bank's prime interest rate minus 1.00% or LIBOR plus 1.50%. In
October 1997, the Company borrowed $4.9 million under this facility to pay off a
subsidiary's previously existing credit facility. On November 28, 1997, the
Company repaid the outstanding balance of this facility with proceeds from the
public offering of its common stock. As of July 31, 1998, there was no
outstanding balance on this facility, resulting in an available borrowing
capacity of $30.0 million.
 
     The outstanding principal under the term loan bears interest at the bank's
prime interest rate minus 0.50% (8.00% at July 31, 1998). Principal and interest
is payable in quarterly installments through April 2003. The outstanding
principal under the term loan was increased to $15.0 million in accordance with
the terms of the amended bank credit agreement. The amount outstanding on the
term loan was $14.3 million at July 31, 1998.
 
     The outstanding loans under the revolving equipment acquisition and small
business purchase facility bear interest, at the option of the Company, at the
bank's prime interest rate minus 0.75% or LIBOR plus 1.75%. At July 31, 1998,
the interest rates on the outstanding revolving equipment and small business
purchase facility were at the LIBOR option ranging from 7.53% to 7.81%. The
advances under the revolving equipment acquisition and small business purchase
facility are converted to term loans with

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
maturities not to exceed 48 months. The outstanding principal on the equipment
term loans is payable in monthly installments through February 2001. In October
1997, the Company borrowed $1.0 million to buy out existing operating leases and
$1.7 million to refinance equipment under a subsidiary's previously existing
credit facility. During the fiscal year ended July 31, 1998, the Company repaid
$1.3 million under this facility. The amount outstanding on the revolving
equipment acquisition and small business purchase facility was $3.3 million at
July 31, 1998 resulting in an available borrowing capacity of $21.7 million.
 
     The Company had outstanding standby letters of credit issued to the
Company's insurance administrators as part of its self-insurance program of
$11.6 million at July 31, 1998.
 
     The amended bank credit agreement contains restrictions which, among other
things, require maintenance of certain financial ratios and covenants, restricts
encumbrances of assets and creation of indebtedness, and limits the payment of
cash dividends. Cash dividends are limited to 50% of each fiscal year's
after-tax profits. No cash dividends have been paid during fiscal 1998. The
amended credit facility is secured by the Company's assets and guaranteed by
each of its subsidiaries. At July 31, 1998, the Company was in compliance with
all of the financial covenants and conditions.
 
     At July 31, 1997, CCG had a $6.6 million revolving bank credit facility of
which $5.9 million was outstanding. The interest rate on this facility was at
the bank's prime interest rate plus 0.75% and was collateralized by 75% of the
eligible trade accounts receivable, inventory, and certain real property owned
by a partnership, whose general partners are the former shareholders of CCG.
This facility was an existing arrangement made by CCG prior to the acquisition
by Dycom. In October 1997, the Company paid off the outstanding balance of $6.6
million and terminated the facility by borrowing $4.9 million against its
revolving working capital facility and $1.7 million against the revolving
equipment acquisition and small business purchase facility.
 
     The Company's recently acquired subsidiaries, CCI and ITI, had credit
facilities entered into prior to the acquisition by Dycom. CCI had a $5.2
million revolving credit facility for funding working capital and a $2.0 million
term note incurred to purchase equipment. The interest rate on the revolving
credit facility was at the bank's prime interest rate and the interest rate on
the term loan was at 8.75%. ITI had a $2.0 million revolving credit facility for
funding working capital and a $0.5 million multiple advance term facility for
equipment acquisitions. The interest rates on the revolving credit facility and
the multiple advance term facility were at the bank's prime interest rate. The
obligations were secured by substantially all of CCI's and ITI's assets. The
facilities contained restrictions, which among other things, required the
maintenance of certain financial ratios and covenants and restricted the payment
of cash dividends. During the fourth quarter of fiscal 1998, the Company paid
off the outstanding balances of $8.1 million under these facilities with
existing cash balances and subsequently terminated such facilities.
 
     In addition to the borrowings under the amended bank credit agreement,
certain subsidiaries have outstanding obligations under capital leases and other
equipment financing arrangements. During fiscal 1998, the Company repaid $2.6
million of outstanding balances on capital lease obligations and other equipment
term loans with existing cash balances. The remaining obligations are payable in
monthly installments expiring at various dates through September 2000.
 
     The estimated aggregate annual principal repayments for notes payable and
capital lease obligations in the next five years are $4,727,782 in 1999,
$4,662,843 in 2000, $3,495,147 in 2001, $3,000,000 in 2002, and $2,250,000 in
2003.
 
     Interest costs incurred on notes payable, all of which is expensed, for the
years ended July 31, 1996, 1997, and 1998 were $2,515,814, $2,619,191, and
$2,045,571, respectively. Such amounts are included in general and
administrative expenses in the accompanying consolidated statements of
operations.

share of CCI's and ITI's taxable income on their personal income tax returns in
lieu of paying corporate income taxes. At April 6, 1998, the consummation date
of the acquisition, CCI and ITI recorded a deferred tax liability (asset) of
$616,358 and $(11,035), respectively, which was included in the third quarter
results of operations. The deferred tax assets and liabilities at July 31 are

     A valuation allowance is provided when it is more likely than not that some
portion of the Company's deferred tax assets will not be realized. The valuation
allowance recorded in the financial statements reduces deferred tax assets to an
amount that represents management's best estimate of the amount of deferred tax
assets that more likely than not will be realized. In fiscal 1997, the Company
reduced the valuation allowance by $0.3 million. In fiscal 1998, the Company
reversed the remaining $475,185 balance

of the valuation allowance. The Company believes that it is more likely than not
that the deferred tax assets will be realized based on the available evidence
supporting the reversing deductible temporary differences being offset by
reversing taxable temporary differences and the existence of sufficient taxable
income within the current carryback periods.
 
     The difference between the total tax provision and the amount computed by
applying the statutory federal income tax rates to pre-tax income is as follows:

11.  CAPITAL STOCK
 
     On June 1, 1992, the Company approved a Shareholder Rights Plan. All
shareholders of record on June 15, 1992 were issued a Right for each outstanding
share of the Company's common stock. Each Right entitles the holder to purchase
one-half share of common stock for an exercise price of $12 subject to
adjustment. The Right is exercisable only when a triggering event occurs. The
triggering events, among others, are a person or group's (1) acquisition of 20%
or more of Dycom's common stock, (2) commencement of a tender offer which would
result in the person or group owning 20% or more of Dycom's common stock, or (3)
acquisition of at least 10% of Dycom's common stock and such acquisition is
determined to have effects adverse to the Company. The Company can redeem the
Rights at $0.01 per Right at any time prior to ten days after a triggering event
occurs.
 
     Certain executive officers of the Company have change of control agreements
with the Company, which provide substantial compensation upon the change of
control of the Company. The payments pursuant to these agreements would be
triggered by any person's acquisition of more than 50% of the

12.  STOCK OFFERING
 
     The Company concluded the public offering of 4,050,000 shares of its common

shareholders offered 1,689,933 shares at an offering price of $13.33 per share.
The Company received $29,736,844 on November 10, 1997 which is net of an
underwriting discount of $0.73 per share. Additionally, the underwriters
exercised their option to purchase 607,500 shares to cover over-allotments. The
Company received $7,654,500 on November 25, 1997 as payment for the
over-allotments. The total offering proceeds, net of offering expenses of
$432,726, are included in stockholders' equity on the July 31, 1998 balance
sheet. On November 28, 1997, the Company repaid the outstanding balance of its
revolving working capital facility and will use the balance of the proceeds to
fund the Company's growth strategy, including acquisitions, working capital and
capital expenditures and for other general corporate purposes.
 
13.  EMPLOYEE BENEFIT PLAN
 
     The Company and certain of its subsidiaries sponsor defined contribution
plans that provide retirement benefits to all employees that elect to
participate. Under the plans, participating employees may defer up to 15% of
their base pre-tax compensation. Generally, the Company's contributions to the
plans are discretionary except for CCI which has a 25% company match up to the
first 5% of the employee's contributions. The Company's contributions were
$158,451, $287,179, and $398,529 in fiscal years 1996, 1997 and 1998,
respectively.
 
14.  STOCK OPTION PLANS
 
     The Company has reserved 1,350,000 shares of common stock under its 1991
Incentive Stock Option Plan (the "1991 Plan") which was approved by the
shareholders on November 25, 1991. The 1991 Plan provides for the granting of
options to key employees until it expires in 2001. Options are granted at the
closing price on the date of grant and are exercisable over a period of up to
five years. Since the 1991 Plan's adoption, certain of the options granted have
lapsed as a result of employees terminating their employment with the Company.
At July 31, 1996, 1997, and 1998, options available for grant under the 1991
Plan were 641,030 shares, 576,177 shares, and 199,782 shares, respectively.
 
     In fiscal 1998, the Company granted to key employees under the 1991 Plan,
options to purchase an aggregate 388,470 shares of common stock. The options
were granted at prices ranging from $12 3/16 to $17.75, prices representing the
fair market value on the date of grant.
 
     On August 24, 1998, the Company granted to key employees under the 1991
Plan options to purchase an aggregate of 211,932 shares of common stock. The
options were granted at $21 3/16, the fair market value on the date of grant.
 
     In addition to the stock option plan discussed above, the Company has
agreements outside of the plan with the non-employee members of the Board of
Directors (the "Directors Plan"). On January 10, 1994, the Company granted to
the non-employee Directors, non-qualified options to purchase an aggregate of
90,000 shares of common stock. The options were granted at $2 9/16, the fair
market value on the date of grant, with vesting over a three-year period.

provisions of SFAS No. 123. The fair value of the options granted in fiscal 1997
and 1998 have been estimated at the date of grant using the Black-Scholes
option-pricing model with the following assumptions: expected stock volatility
of 58.97% in 1997 and 55.36% in 1998; risk-free interest rates of 6.57% in 1997
and 5.50% in 1998; expected lives of 4 years for 1997 and 1998, and no dividend
yield in both years, due to the Company's recent history of not paying cash
dividends.
 
     The Black-Scholes option valuation model was developed for estimating the
fair value of traded options that have no vesting restrictions and are fully
transferable. Because option valuation models require the use of subjective
assumptions and changes in these assumptions can materially impact the fair
value of the options and the Company's options do not have the characteristics
of traded options, the option valuation models do not necessarily provide a
reliable measure of the fair value of its options. The estimated fair value of
stock options granted during fiscal 1997 and 1998 was $4.65 and $6.75 per share,
respectively.
 
     The pro forma disclosures amortize to expense the estimated compensation
costs for its stock options granted subsequent to July 31, 1996 over the options
vesting period. The Company's fiscal 1996, 1997 and 1998 pro forma net earnings
and earnings per share are reflected below:

15.  RELATED PARTY TRANSACTIONS
 
     The Company's subsidiary, CCG, leases administrative offices from a
partnership of which certain officers of the subsidiary are the general partners
and the Company's newly acquired subsidiaries, CCI and ITI, lease administrative
offices from a corporation of which certain officers of the subsidiaries are
shareholders. ITI advanced the corporation $268,860 for leasehold improvements
to its administrative office building. The amount advanced was fully reimbursed
by July 31, 1998. The total expense under these arrangements for the years ended
July 31, 1996, 1997, and 1998 was $184,200, $242,310, and $304,010,
respectively. The future minimum lease commitments under these arrangements are
$299,760 in 1999, $299,760 in 2000, $203,760 in 2001 and $80,900 in 2002.

16.  MAJOR CUSTOMERS AND CONCENTRATION OF CREDIT RISK
 
     The operating subsidiaries obtain contracts from both public and private
concerns. For the years ended July 31, 1996, 1997, and 1998, approximately 36%,
27%, and 22%, respectively, of the contract revenues were from BellSouth
Telecommunications, Inc. ("BellSouth"), 16%, 18%, and 24%, respectively, of the
contract revenues were from Comcast Cable Communications, Inc. ("Comcast"), and
6.4%, 6.3%, and 7.2%, respectively, of the contract revenues were from GTE
Corporation ("GTE").
 
     Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of trade accounts receivable.
BellSouth, Comcast, and GTE represent a significant portion of the Company's
customer base. As of July 31, 1997, the total outstanding trade receivables from
BellSouth, Comcast, and GTE were $5.7 million or 12%, $11.5 million or 23%, and
$2.2 million or 4%, respectively, of the outstanding trade receivables. At July
31, 1998, the total outstanding trade receivables from BellSouth, Comcast, and
GTE were $7.9 million or 13%, $16.9 million or 27%, and $2.3 million or 4%,
respectively, of the Company's outstanding trade receivables.
 
17.  COMMITMENTS AND CONTINGENCIES
 
     The Company and its subsidiaries have operating leases covering office
facilities, vehicles, and equipment which have noncancelable terms in excess of
one year. During fiscal 1996, 1997, and 1998, the Company entered into numerous
operating leases for vehicles and equipment. Certain of these leases contain
renewal provisions and generally require the Company to pay insurance,
maintenance, and other operating expenses. Total expense incurred under
operating lease agreements, excluding the transactions with related parties (see
Note 15), for the years ended July 31, 1996, 1997, and 1998, was $5,305,237,
$6,732,699, and $6,754,934, respectively. The future minimum obligations under
these leases are $4,599,287 in 1999; $2,046,435 in 2000; $954,796 in 2001;
$526,526 in 2002, $323,338 in 2003 and $56,900 thereafter.
 
     In September 1995, the State of New York commenced a sales and use tax
audit of CCG for the years 1989 through 1995. As a result of the audit, certain
additional taxes were paid by CCG in fiscal 1996. In addition, the State of New
York concluded that cable television service providers are subject to New York
State sales taxes for the construction of cable television distribution systems,
and by a Notice dated January 1997, asserted amounts due from CCG for sales
taxes and interest for the periods through August 31, 1995, aggregating
approximately $1.3 million. Any sales taxes asserted against the Company may be
offset by use taxes already paid by customers of the Company. The Company
intends to vigorously contest the assertion. The Company is unable to assess the
likelihood of any particular outcome at this time or to quantify the effect a
resolution of this matter may have on the Company's consolidated financial
statements.
 
     In the normal course of business, certain subsidiaries of the Company have
pending and unasserted claims. It is the opinion of the Company's management,
based on the information available at this time, that these claims will not have
a material adverse impact on the Company's consolidated financial statements.
 
18.  QUARTERLY FINANCIAL DATA (UNAUDITED)
 
     The Company has historically experienced variability in revenues, income
before income taxes and net income on a quarterly basis. A significant amount of
this variability is due to the fact that the Company's business is subject to
seasonal fluctuations, with activity in its second and occasionally third fiscal
quarters (the quarters ended January 31 and April 30 in a given fiscal year)
being adversely affected by weather. In addition, budgetary spending patterns of
significant customers, which often run on a calendar year basis, have resulted
in greater volatility of second fiscal quarter results.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     In the opinion of management, the following unaudited quarterly data for
the years ended July 31, 1997 and 1998 reflect all adjustments necessary for the
fair presentation of a statement of operations. All such adjustments are of a
normal recurring nature other than as discussed below. The Company acquired CCI
and ITI ("Pooled Companies") on April 6, 1998. The acquisitions were accounted
for as poolings of interests and accordingly, the unaudited quarterly financial
statements for the periods presented include the accounts of CCI and ITI. The
quarterly data for CCI and ITI for the quarter including the consummation date
of the mergers and the subsequent quarter are included in the Dycom data. The
earnings per common share calculation for each quarter is based on the weighted
average shares of common stock outstanding plus the dilutive effect of stock
options. The sum of the quarters earnings per common share may not necessarily
be equal to the full year earnings per common share amounts.

19.  SUBSEQUENT EVENT
 
     On December 14, 1998, the Board of Directors declared a 3-for-2 split of
the Company's common stock, effected in the form of a stock dividend paid on
January 4, 1999 to stockholders of record on December 23, 1998. All agreements
concerning stock options provide for the issuance of additional shares due to
the declaration of the stock split. An amount equal to the par value of the
common shares issued plus cash paid in lieu of fractional shares was transferred
from capital in excess of par value to the common stock account. All references
to number of shares and to per share information have been adjusted to reflect
the stock split on a retroactive basis.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
1.  The accompanying condensed consolidated balance sheets of Dycom Industries,
Inc. ("Dycom" or the "Company") as of July 31, 1998 and January 31, 1999, and
the related condensed consolidated statements of operations for the three and
six months ended January 31, 1998 and 1999, respectively, and the condensed
consolidated statements of cash flows for the six months ended January 31, 1998
and 1999 reflect all normal recurring adjustments which are, in the opinion of
management, necessary for a fair presentation of such statements. The results of
operations for the three and six months ended January 31, 1999 are not
necessarily indicative of the results which may be expected for the entire year.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Principles of Consolidation -- The condensed consolidated financial
statements are unaudited. These statements include Dycom Industries, Inc. and
its subsidiaries, all of which are wholly owned. On April 6, 1998, the Company
consummated the Cable Com Inc. ("CCI") and Installation Technicians, Inc.
("ITI") acquisitions and issued 1.8 million and 900,000 shares of common stock
in exchange for all the outstanding capital stock of CCI and ITI, respectively.
These acquisitions were accounted for as poolings of interests and accordingly,
the Company's condensed consolidated financial statements include the results of
CCI and ITI for all periods presented. Prior to the acquisitions, CCI and ITI
used a fiscal year consisting of a 52/53 week time period and, as a result of
the merger, have adopted Dycom's fiscal year end of July 31. All periods
presented reflect the adoption of such fiscal year end as of the beginning of
the period.
 
     The Company is a leading provider of engineering, construction and
maintenance services to telecommunications providers and also performs
underground utility locating services and electrical construction and
maintenance contracting services. All material intercompany accounts and
transactions have been eliminated.
 
     Pro Forma Adjustments -- Prior to the acquisition by Dycom, CCI and ITI
elected under Subchapter S of the Internal Revenue Code to have the stockholders
recognize their proportionate share of CCI's and ITI's taxable income on their
personal tax returns in lieu of paying corporate income tax. The pro forma net
income and earnings per common share on the condensed consolidated statements of
operations reflect a provision for current and deferred income taxes for all
periods presented as if the corporations were included in Dycom's federal and
state income tax returns. At April 6, 1998, the consummation date of the
acquisition, CCI and ITI recorded deferred taxes on the temporary differences
between the financial reporting basis and the tax basis of their assets and
liabilities. The deferred tax (asset) liability recorded by CCI and ITI was
$616,358 and $(11,035), respectively.
 
     Use of Estimates -- The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates and such differences may be material to the financial statements.
 
     Estimates are used in the Company's revenue recognition of work-in-process,
allowance for doubtful accounts, self-insured claims liability, deferred tax
asset valuation allowance, depreciation and amortization, and in the estimated
lives of assets, including intangibles.
 
     Revenue -- Income on short-term contracts is recognized as the related work
is completed. Work-in-process on unit contracts is based on management's
estimate of work performed but not billed. Income on long-term contracts is
recognized on the percentage-of-completion method based primarily on the ratio
of contract costs incurred to date to total estimated contract costs. At the
time a loss on a contract becomes known, the entire amount of the estimated
ultimate loss is accrued.

      NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     "Costs and estimated earnings in excess of billings" represents the excess
of contract revenues recognized under the percentage-of-completion method of
accounting for long-term contracts and work-in-process on unit contracts over
billings to date. For those contracts in which billings exceed contract revenues
recognized to date, such excesses would be included in the caption "billings in
excess of costs and estimated earnings".
 
     Cash and Equivalents -- Cash and equivalents include cash balances on
deposit in banks, overnight repurchase agreements, certificates of deposit,
commercial paper, and various other financial instruments having an original
maturity of three months or less. For purposes of the condensed consolidated
statements of cash flows, the Company considers these amounts to be cash
equivalents.
 
     Property and Equipment -- Property and equipment is stated at cost.
Depreciation and amortization is computed over the estimated useful life of the
assets utilizing the straight-line method. The estimated useful service lives of
the assets are: buildings -- 20-31 years; leasehold improvements -- the term of
the respective lease or the estimated useful life of the improvements, whichever
is shorter; vehicles -- 3-7 years; equipment and machinery -- 2-10 years; and
furniture and fixtures -- 3-10 years. Maintenance and repairs are expensed as
incurred; expenditures that enhance the value of the property or extend its
useful life are capitalized. When assets are sold or retired, the cost and
related accumulated depreciation are removed from the accounts and the resulting
gain or loss is included in income.
 
     Intangible Assets -- The excess of the purchase price over the fair market
value of the tangible net assets of acquired businesses (goodwill) is amortized
on a straight-line basis over 40 years. The appropriateness of the carrying
value of goodwill is reviewed periodically by the Company. An impairment loss is
recognized when the projected future cash flows is less than the carrying value
of goodwill. No impairment loss has been recognized in the periods presented.
Non-compete agreements obtained through the purchase of business assets are
amortized on a straight-line basis over the term of the agreements.
 
     Amortization expense was $77,545 and $83,741 for the six month periods
ended January 31, 1998 and 1999, respectively. The intangible assets are net of
accumulated amortization of $1,306,446 at July 31, 1998 and $1,390,188 at
January 31, 1999.
 
     Self-Insured Claims Liability -- The Company is primarily self-insured, up
to certain limits, for automobile and general liability, workers' compensation,
and employee group health claims. A liability for unpaid claims and the
associated claim expenses, including incurred but not reported losses, is
actuarially determined and reflected in the condensed consolidated financial
statements as an accrued liability. The self-insured claims liability includes
incurred but not reported losses of $5,120,000 and $7,330,000 at July 31, 1998
and January 31, 1999, respectively. The determination of such claims and
expenses and the appropriateness of the related liability is continually
reviewed and updated.
 
     Income Taxes -- The Company and its subsidiaries, except for CCI and ITI,
file a consolidated federal income tax return. CCI and ITI were included in the
Company's consolidated federal income tax return effective April 6, 1998.
Deferred income taxes are provided for the temporary differences between the
financial reporting basis and the tax basis of the Company's assets and
liabilities.
 
     Per Share Data -- Earnings per common share-basic is computed using the
weighted-average common shares outstanding during the period. Earnings per
common share-diluted is computed using the weighted-average common shares
outstanding during the period and the dilutive effect of common stock options,
using the treasury stock method. See Note 3.
 
     Recently Issued Accounting Pronouncements -- In June 1997, the Financial
Accounting Standards Board ("FASB") issued Statement of Financial Accounting
Standards ("SFAS") No. 130 "Reporting Comprehensive Income" which establishes
standards for reporting and display of comprehensive income and its components
(revenues, expenses, gains and losses) in a full set of general purpose
financial

statements. This statement requires that an enterprise classify items of other
comprehensive income by their nature in a financial statement and display the
accumulated balance of other comprehensive income separately from retained
earnings and additional paid-in capital in the equity section of a statement of
financial position. This statement is effective for fiscal years beginning after
December 15, 1997.
 
     In June 1997, the FASB issued SFAS No. 131 "Disclosure about Segments of an
Enterprise and Related Information" which establishes standards for public
business enterprises to report information about operating segments in annual
financial statements and requires those enterprises to report selected
information about operating segments in interim financial reports issued to
shareholders. It also establishes the standards for related disclosures about
products and services, geographic areas, and major customers. This statement
requires that a public business enterprise report financial and descriptive
information about its reportable operating segments. The financial information
is required to be reported on the basis that it is used internally for
evaluating segment performance and deciding how to allocate resources to
segments. Operating segments are components of an enterprise about which
separate financial information is available that is evaluated regularly by the
chief operating decision maker in deciding how to allocate resources and in
assessing performance. This statement is effective for fiscal years beginning
after December 15, 1997.
 
     In February 1998, the FASB issued SFAS No. 132 "Employers' Disclosures
about Pension and Other Postretirement Benefits", which revises certain
disclosures about pension and other postretirement benefit plans. This statement
does not change the measurement and recognition methods for pensions or
postretirement benefit costs reported in financial statements. This statement is
effective for fiscal years beginning after December 15, 1997.
 
     In June 1998, the FASB issued SFAS No. 133 "Accounting for Derivative
Instruments and Hedging Activities" which establishes standards for the
accounting and reporting of derivative instruments, including certain derivative
instruments embedded in other contracts, (collectively referred to as
derivatives) and for hedging activities. It requires that an entity recognize
all derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. This statement is
effective for all fiscal quarters of all fiscal years beginning after June 15,
1999.
 
     Management is currently evaluating the requirements and related disclosures
of SFAS No. 130, 131, 132, and 133.
 
3.  EARNINGS PER SHARE
 
     In February 1997, the FASB issued SFAS No. 128 "Earnings per Share" which
changes the method of calculating earnings per share and was effective for the
Company in the quarter ended January 31, 1998. All periods presented have been
restated in accordance with the provisions of SFAS No. 128.
 
     On December 14, 1998, the Board of Directors declared a three-for-two split
of the Company's common stock, effected in the form of a stock dividend paid on
January 4, 1999 to shareholders of record on December 23, 1998. All agreements
concerning stock options provide for the issuance of additional shares due to
the declaration of the stock split. An amount equal to the par value of the
common shares issued plus cash paid in lieu of fractional shares was transferred
from capital in excess of par value to the common stock account. All references
to number of shares and to per share information have been adjusted to reflect
the stock split on a retroactive basis.

</TABLE>
 
     On April 29, 1998, the Company signed an amendment to its bank credit
agreement increasing the total facility to $85.0 million. The amended bank
credit agreement provides for (i) a $30.0 million revolving working capital
facility; (ii) a $15.0 million standby letter of credit facility; (iii) a $25.0
million revolving equipment acquisition and small business purchase facility;
and (iv) a $15.0 million five-year term loan. The revolving working capital
facility, the standby letter of credit facility and the revolving equipment
facility are available for a two-year period.
 
     The revolving working capital facility bears interest, at the option of the
Company, at the bank's prime interest rate minus 1.00% or LIBOR plus 1.50%. As
of January 31, 1999, there was no outstanding balance on this facility resulting
in an available borrowing capacity of $30.0 million.
 
     The Company had outstanding standby letters of credit issued to the
Company's insurance administrators as part of its self-insurance program of
$11.4 million at January 31, 1999.
 
     The outstanding loans under the revolving equipment acquisition and small
business purchase facility bear interest, at the option of the Company, at the
bank's prime interest rate minus 0.75% or LIBOR plus 1.75%. At January 31, 1999,
the interest rate on the outstanding revolving equipment and small business
purchase facility were at the LIBOR option of 7.00%. The advances under the
revolving equipment acquisition and small business purchase facility are
converted to term loans with maturities not to exceed 48 months. The outstanding
principal on the equipment term loans is payable in monthly installments through
February 2001. The amount outstanding on the revolving equipment acquisition and
small business purchase facility was $2.6 million at January 31, 1999, resulting
in an available borrowing capacity of $22.4 million.
 
     The outstanding principal under the term loan bears interest at the bank's
prime interest rate minus 0.50% (7.25% at January 31, 1999). Principal and
interest is payable in quarterly installments through April 2003. The amount
outstanding on the term loan was $12.8 million at January 31, 1999.
 
     The amended bank credit agreement contains restrictions which, among other
things, requires maintenance of certain financial ratios and covenants,
restricts encumbrances of assets and creation of indebtedness, and limits the
payment of cash dividends. Cash dividends are limited to 50% of each fiscal
year's after-tax profits. No cash dividends were paid during the three and six
month periods ended January 31, 1999. The amended bank credit facility is
secured by the Company's assets and guaranteed by each of its subsidiaries. At
January 31, 1999, the Company was in compliance with all financial covenants and
conditions.

      NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     In addition to the borrowings under the amended bank credit agreement,
certain subsidiaries have outstanding obligations under capital leases and other
equipment financing arrangements. The obligations are payable in monthly
installments expiring at various dates through January 2002.
 
     Interest costs incurred on notes payable, all of which were expensed for
the three month period ended January 31, 1998 and 1999 were $461,656 and
$316,530, respectively. Interest costs for the six month period ended January
31, 1998 and 1999 were $1,097,845 and $665,080, respectively. Such amounts are
included in general and administrative expenses in the accompanying condensed
consolidated statements of operations.
 
8.  COMMITMENTS AND CONTINGENCIES
 
     In September 1995, the State of New York commenced a sales and use tax
audit of Communications Construction Group, Inc. ("CCG"), a wholly-owned
subsidiary, for the years 1989 through 1995. As a result of the audit, certain
additional taxes were paid by CCG in fiscal 1996. In addition, the State of New
York concluded that cable television service providers are subject to New York
State sales taxes for the construction of cable television distribution systems,
and by a Notice dated January 1997, asserted amounts due from CCG for sales
taxes and interest for the periods through August 31, 1995, aggregating
approximately $1.3 million. Any sales taxes asserted against the Company may be
offset by use taxes already paid by the customers of the Company. The Company
intends to vigorously contest the assertion. The Company is unable to assess the
likelihood of any particular outcome at this time or to quantify the effect a
resolution of this matter may have on the Company's consolidated financial
statements.
 
     In the normal course of business, certain subsidiaries of the Company have
pending and unasserted claims. It is the opinion of the Company's management,
based on the information available at this time, that these claims will not have
a material adverse impact on the Company's consolidated financial statements.
 
9.  SUBSEQUENT EVENT
 
     On February 3, 1999, the Company acquired all of the outstanding common
stock of Locating, Inc. for $10.0 million. Located in Issaquah, Washington,
Locating, Inc.'s primary line of business is the locating, marking, and mapping
of underground utility facilities for cable television, multiple system
operators, telephone companies, and electrical and gas utilities. The Company
intends to record this transaction as a purchase.

                             BASIS OF PRESENTATION
 
     On March 31, 1999, pursuant to a stock purchase agreement, we purchased all
of the issued and outstanding shares of common stock of Ervin Cable
Construction, Inc. ("ECC") for $21,750,000 in cash and 258,066 shares of our
common stock. On April 1, 1999, pursuant to a merger agreement we issued an
aggregate of 516,128 shares of our common stock to the shareholders of Apex
Digital TV, Inc. ("Apex") in exchange for all the issued and outstanding common
stock of Apex. Prior to the acquisitions, the three stockholders of ECC held 80%
of the outstanding shares of common stock of Apex.
 
     The accompanying pro forma unaudited condensed consolidated financial
statements are based on the historical financial presentation of our
consolidated financial statements, ECC, Apex and Locating, a Washington
corporation we acquired for $10 million in February 1999. The pro forma
unaudited condensed consolidated financial statements and related notes give
effect to these acquisitions under the purchase method of accounting. The
accompanying pro forma unaudited condensed consolidated financial statements
should be read in conjunction with our consolidated financial statements and
notes thereto included in this prospectus and the historical financial
statements of ECC and Apex, which are incorporated in this prospectus by
reference.
 
     The pro forma unaudited condensed consolidated balance sheet presents our
financial position as if the acquisitions had been completed on January 31,
1999. The pro forma unaudited condensed consolidated statement of operations for
the six month period ended January 31, 1999 and for the fiscal year ended July
31, 1998 assume that the acquisitions occurred as of the beginning of the
periods presented. The pro forma unaudited condensed consolidated financial
statements are presented for illustrative purposes only. They do not purport to
be indicative of the financial position or results of operations of Dycom, that
would have actually been presented, or which may be obtained in the future. The
pro forma unaudited condensed consolidated financial statements do not include
any likely cost savings or any synergies that are likely to occur from the
acquisitions and there can be no assurances that any such cost savings or
synergies will occur. The pro forma adjustments are described in the
accompanying notes and are based upon available information and certain
assumptions that we believe are reasonable.
 
     A preliminary allocation of the purchase price has been made to major
categories of assets and liabilities in the accompanying pro forma unaudited
condensed consolidated financial statements based on available information. The
actual allocation of the purchase price and the resulting effect on income from
operations may differ significantly from the pro forma amounts included herein.
These pro forma adjustments represent our determination of purchase accounting
adjustments and are based upon available information and certain assumptions
that we believe to be reasonable. As such, the amounts reflected in the pro
forma unaudited condensed consolidated financial statements are subject to
change, and final amounts may differ significantly.

                     NOTES TO PRO FORMA UNAUDITED CONDENSED
                       CONSOLIDATED FINANCIAL STATEMENTS
 
(1) ACCOUNTING PERIODS
 
     Prior to the acquisitions, ECC and Apex had used a calendar year end and as
a result of the merger have adopted our fiscal year end of July 31. All periods
presented reflect the adoption of such fiscal year end as of the beginning of
the period. Our consolidated balance sheet as of January 31, 1999 has been
combined with ECC's and Apex's balance sheet as of the same date. Our
consolidated statements of operations for the six months ended January 31, 1999
and for the fiscal year ended July 31, 1998 have been combined with ECC's and
Apex's results of operations for the same periods.
 
(2) MERGER COSTS
 
     Dycom, ECC and Apex estimate they will incur direct transaction costs of
approximately $475,000 associated with the acquisitions, consisting of fees for
filing with regulatory agencies, legal, accounting and other related costs.
These costs, together with approximately $206,000 of estimated transaction costs
related to the acquisition of Locating, have been accrued. These nonrecurring
costs are included in goodwill.
 
(3) PROVISION FOR INCOME TAXES
 
     Prior to the acquisitions, Locating, ECC and Apex elected under Subchapter
S of the Internal Revenue Code to have the stockholders recognize their
proportionate share of Locating's, ECC's and Apex's taxable income on their
personal income tax returns in lieu of paying corporate income tax. The
unaudited pro forma financial information reflects a provision for current and

improvements -- the term of the respective lease or the estimated useful life of
the improvements, whichever is shorter; vehicles -- 2 to 7 years; equipment and

adjustment of approximately $5,080,000 for stockholder distributions subsequent
