Letter to Our Shareholders

2002 proved to be an historic year for ManTech

International Corporation. On all fronts, we

ended the year stronger than at any time in the company’s
history, and we believe we are well positioned to continue
this positive momentum in 2003.

2002 started with our February initial public offering,
which raised over $110 million for the company—perhaps
the most important step in the company’s 34-year history. The
IPO was the culmination of the first phase of a strategy that
we formulated and began executing in January 2001. Our
goal was to commit fully to our core business with the U.S.
Federal Government, especially our Department of Defense
and intelligence community programs where we identified
positive budgetary spending trends and ample opportunities
to deliver information technology and technical services solutions.

The IPO, however, was simply the start of a remarkable
year. In each quarter, ManTech delivered impressive results.
Our revenue increased nearly 16% over 2001, and we com-
pleted two acquisitions that provided access to new customers
and technical skill sets in high-growth markets within the
Department of Defense and the intelligence community.

At this writing in 2003, two additional acquisitions have
been completed. Combined with our original core business,
the four acquisitions to date, we believe, will have a transfor-
mational effect on ManTech.

During 2002, we executed our acquisition program while

focusing sharply on the operation of the company. The top
line growth described above was complemented by similar
expansion in our earnings—both income from continuing
operations and net income increased substantially over 2001.

Our backlog at the end of 2002 was very healthy, and our
total staffing grew to over 4,400, with over 1,000 serving
abroad in support of U.S. Government customers.

We finished 2002 in December with a return to the equity
markets for a follow-on offering in which we raised over $90
million for ManTech, primarily to fund the acquisitions
described above.

As shareholders of ManTech, you can expect us to 
continue our tradition of outstanding support for priority 
U.S. Government programs. “Managing technology” for our
customers was the founding principle of our company, and 
it continues to sustain us today.

In closing, please remember that our employees are

ManTech’s greatest asset, and they deserve our praise and
appreciation for another year of excellent performance. At
this writing, some of our colleagues are working for ManTech
in locations such as Iraq, Afghanistan, and the Balkans. As is
the tradition of the customers we support, as we diligently
pursue our work here at home, those in harm’s way should
always be first in our minds and hearts.

Thank you for your support and confidence in ManTech

in 2002. We look forward to a promising 2003.

Sincerely,

George J. Pedersen
Chairman of the Board, CEO and President

Business Overview

ManTech International Corporation delivers a broad array of information technology and technical services
solutions to U.S. federal government customers, focusing primarily on critical national defense programs for the
intelligence community and Department of Defense. With 2002 revenue of $500.2 million, ManTech designs,
develops, procures, implements, operates, tests and maintains mission-critical, enterprise information technology
and communication systems and intelligence processing infrastructures for the Company’s federal government
customers. Many of the Company’s 4,436 employees have military or intelligence experience and high level
security clearances that allows the Company to work with its customers in highly classified environments and at
front-line deployments in the United States and 34 countries globally.

The Company was founded in 1968 and has exhibited strong growth and profitability since 1980 largely as a
result of successful long-standing relationships with its customers, having supported many of them for 15 to 30
years. For the years ended December 31, 2002, 2001 and 2000, approximately 86.7%, 85.1% and 84.0%,
respectively, of the Company’s revenues were derived from its customers in the intelligence community and
Department of Defense. These customers include the Office of the Secretary of Defense; the Department of State;
various intelligence agencies; the U.S. Army, Navy, Air Force and Marine Corps; and joint military commands.
The Company also provides solutions to federal government civilian agencies, including NASA, EPA and the
Departments of Justice, Commerce and Energy, as well as to state and local governments and commercial
customers.

ManTech’s Services

The Company delivers comprehensive information technology and technical services solutions for mission-
critical, enterprise information technology and communication systems through three principal areas of expertise,
which are offered separately or in combination across the Company’s customer base:

Secure Systems and Infrastructure Solutions

The Company provides a broad range of solutions to enhance systems and network availability and mission-
critical performance of its customers’ hardware, software, computer, network and telecommunication assets,
including:

Intelligence Operations. The Company provides services for strategic and tactical
intelligence systems,
networks and facilities in support of the intelligence community and Department of Defense. To support

2

classified systems and facilities designed to collect, analyze, process and report on signals intelligence, the
Company develops and integrates advanced signal processing systems and new signal processing techniques. The
Company’s intelligence-related services also include the design, rapid development and prototyping, integration
and management of real-time signal processing systems. For example, when an adversary implements a new
communication technique or protocol, the Company provides rapid prototyping and re-engineering services,
which enable its customers in the intelligence community to decipher and exploit the communications.

Communication Systems and Infrastructure Support. The Company designs, develops, modifies and maintains
secure communication systems and network infrastructures. This process involves evaluating industry standards,
systems architectures and applications in order to recommend and develop technology solutions and integrate
them into a customer’s secure communication systems. The Company also procures, installs and tests new voice,
data and video communication systems. For example, the Company provided a comprehensive communication
network infrastructure and systems solution in relocating, re-establishing and upgrading a major military
command headquarters from Panama to Miami, Florida. The Company integrated the customer’s classified and
unclassified information processing and telecommunication network without disruption to the command mission.

Infrastructures. The Company identifies potential

detection programs that are compatible with their evolving virtual private network architecture.

Secrecy Management and Program Security Architecture. The Company provides secrecy management and
security infrastructure services for highly classified programs including intelligence operations and military
programs. Due to the highly sensitive and classified nature of these programs, opportunities are often limited to a
select number of providers that possess the requisite capabilities, qualifications and special access clearances.
The Company’s involvement in these programs often begins in the initial or concept phase. The Company
identifies critical elements that require protection and then helps design the program to protect those critical
elements throughout the program life cycle. The Company provides secrecy and security services including
vulnerability assessment, exposure analysis, secrecy architecture design, security policy development and
implementation, life cycle acquisition program security, system security engineering, security awareness and
training, comprehensive security support services and technical certification and accreditation services. For
example, the Company provides special access security support to the Joint Strike Fighter Program and the
Department of Defense Counterintelligence Field Activity Office.

Systems integration services. The Company performs comprehensive systems integration of hardware and
software components for the Company’s government and commercial customers using commercial products and

3

its customers’ proprietary software and legacy applications. The Company analyzes customer information
systems, applications and platforms and develops solutions to sustain or extend systems performance and
availability. For example, as a subcontractor on the Navy-Marine Corps Intranet program, the Company is
transitioning legacy software applications to a standardized, end-to-end systems infrastructure for voice, video
and data. This includes support of over 10,000 critical legacy business applications serving 350,000 Navy
personnel, which must be migrated to the new program architecture. The Company also develops and provides
specialized training programs for information systems, including interactive electronic training and technical
manuals and enterprise-wide distance learning programs. The Company is working with the Internal Revenue
Service’s General Business Institute to design, develop and implement a web-based training management and
delivery solution that provides access to more than 100 training courses via their intranet or the Internet.

In addition, the Company performs database conversion and application migration services for its customers. For
example, the Company developed a software tool that enhances its database conversion and application migration
services. This solution automates the database conversion process to enable better, faster and less expensive
conversions and migrations.

Enterprise application solutions. The Company designs, develops, implements,
tests, maintains and web
enables software applications for its customers’ information systems and network infrastructures. The Company

ManTech’s Customers

The Company’s customers include U.S. federal government intelligence, military and civilian agencies, state and
local governments and commercial customers. The Company has successful, long-standing relationships with its
customers, having supported many of them for 15 to 30 years. Representative customers include:

•

Intelligence and Department of Defense Customers
❑ Office of the Secretary of Defense
❑ U.S. Army, Navy, Air Force and Marine Corps
❑ Multiple Intelligence and Classified Agencies
❑ Department of State
❑ National Reconnaissance Office
❑ Defense Information Systems Agency
❑ Defense Logistics Agency
❑ Defense Commissary Agency
❑ Joint Interoperability Test Command

• Civilian Agencies or Departments
❑ Department of Energy
❑ Department of Justice
❑ National Aeronautics and Space Administration
❑ Environmental Protection Agency
❑ Internal Revenue Service
❑ National Institutes of Health, including the National Cancer Institute

The Company’s revenues derived from its federal government customers, consisting primarily of customers in
the intelligence community and Department of Defense, accounted for approximately 96.3%, 96.2% and 96.1%
of its revenues for 2002, 2001 and 2000, respectively. The Company’s federal government customers typically
exercise independent contracting authority, and even offices or divisions within an agency or department may
directly, or through a prime contractor, use the Company’s services as a separate customer so long as that
customer has independent decision-making and contracting authority within its organization. For example, under
a blanket purchasing agreement with one of the Army’s contracting agencies, program managers throughout the
Army and from other services and defense agencies are able to purchase a wide range of the Company’s
solutions. Even though task orders under this agreement together accounted for 10.0% of the Company’s
revenues for the year ended December 31, 2002, no one task order represented more than 2.5% of the Company’s
revenues during that period.

For 2002 and 2001, the Company derived 9.2% and 8.1%, respectively, of its revenues through relationships with
prime contractors, who contract directly with the customer and subcontract to the Company.

Foreign Operations

In 2002, 99.4% of the Company’s revenue was derived from services provided under contracts with U.S.-based
customers and 0.6% of 2002 revenue came from contracts with foreign customers. In 2001, 98.6% and 1.4% of
revenue was derived from services provided for U.S. and foreign-based customers, respectively. In 2000, 98.7%
and 1.3% of revenue was derived from services provided for U.S. and foreign-based customers, respectively. The
Company treats sales to United States government customers as sales within the United States, regardless of
where the services are performed.

Backlog and GSA Schedule Contract Value

At December 31, 2002, the Company’s backlog was $1,354.8 million, of which $196.7 million was funded
backlog. At December 31, 2001, the Company’s backlog was $907.5 million, of which $206.8 million was
funded backlog. In addition, the Company estimates its GSA schedule contract value at December 31, 2002 was
the Company estimates its GSA schedule contract value was
$914.8 million. At December 31, 2001,
$864.8 million. Backlog, funded backlog and GSA schedule contract value represent estimates that the Company
calculates on the bases described below. The Company expects that more than 94.0% of its funded backlog at
December 31, 2002 will be recognized as revenues prior to December 31, 2003.

The Company defines backlog as its estimate of the remaining future revenues from existing signed contracts,
assuming the exercise of all options relating to such contracts and including executed task orders issued under
GSA schedule contracts. This includes an estimate of revenues for solutions that the Company believes it will be
asked to provide in the future under the terms of executed multiple-award contracts in which the Company is not
the sole provider, meaning that the customer could turn to companies other than ManTech to fulfill the contract.
It also includes an estimate of revenues from indefinite delivery, indefinite quantity contracts, which specify a
maximum, but only a token minimum, amount of goods or services that may be provided under the contract.
Backlog does not include the value for contracts where the Company has been given permission by the customer
to begin or continue working, but where a formal contract or contract extension has not yet been signed.

The Company defines funded backlog to be the portion of backlog for which funding currently is appropriated
and allocated to the contract by the purchasing agency or otherwise authorized for payment by the customer upon
completion of a specified portion of work. The Company’s funded backlog does not include the full value of its
contracts, because Congress often appropriates funds for a particular program or contract on a yearly or quarterly
basis, even though the contract may call for performance that is expected to take a number of years.

At December 31, 2002, the Company’s backlog included $270.0 million of revenues for solutions pursuant to
task orders that have been executed under GSA schedule contracts, of which $63.4 million was included in
funded backlog. The amount of the Company’s revenues generated under GSA schedule contracts has increased
in recent years. Specifically, for the years ended December 31, 2002, 2001 and 2000, funded awards under GSA
schedule contracts were $177.5 million, $155.6 million and $135.2 million, respectively. The Company believes
that potential GSA schedule contract revenues are not fully reflected in traditional backlog calculations because,
as described below, while GSA schedule contracts provide the Company’s customers with the flexibility to
obtain the Company’s solutions through a streamlined procurement process, they do not provide for fixed,
minimum or maximum purchase commitments. Therefore, the Company has developed a method of calculating
GSA schedule contract value that it uses to evaluate estimates for the amount of revenues that it may receive
under its GSA schedule contracts. For these purposes, the Company determines GSA schedule contract value by
multiplying the average monthly amount of funded work that it has been awarded under each of its GSA
schedule contracts over the past twelve months, by the number of months remaining in the term of those
contracts, including under existing options, except that the Company does not take into account remaining
contract terms of more than 72 months.

GSA schedule contracts are competitively awarded government-wide acquisition contracts negotiated and
awarded by the General Services Administration and effectively act as fixed-price or time-and-materials
contracts which government agencies may, but are not required to, use to purchase professional services and
information technology products at predetermined ceiling prices, terms and conditions. Many of the Company’s
customers are authorized to use GSA schedule contracts through blanket purchase agreements, which operate
similarly to GSA schedule contracts by permitting one or more federal agencies to purchase professional services
or products from technology service providers at predetermined prices, terms and conditions. GSA schedule
contracts are master agreements that do not, by themselves, authorize the delivery of services or products.
Therefore, even though the Company has been awarded a GSA schedule contract or blanket purchase agreement,
it often must actively solicit post-award sales, and it remains difficult for it to estimate the amount of work, if
any, it will obtain under the contract.

7

GSA schedule contracts benefit the Company’s federal government customers in a number of ways. First, they
provide customers a streamlined means to competitively obtain professional services and technology products,
allowing for a more efficient and timely procurement process. Second, because the Company must actively
promote its services and technology to obtain work under these types of agreements, the customer benefits from
continued competition. Third, as with fixed-price or time-and-materials contracts, GSA schedule contracts shift
the risks of cost overruns to the technology service provider and promote effective contract management and
cost-efficiencies by allowing the technology service provider to receive the benefit of cost savings that it
generates. Although the Company must compete for or solicit individual task orders under GSA schedule
contracts, it has found that GSA schedule contracts benefit companies such as ManTech that can respond quickly
to emerging customer requirements and can manage contract performance efficiently. Finally, as with traditional
fixed-price contracts, GSA schedule contracts involve greater financial risk, but the Company believes they offer
opportunities for higher profitability because the Company bears the impact of cost overruns and receives the
benefit of cost savings.

Changes in the amount of the Company’s backlog, funded backlog and GSA schedule contract value result from
potential future revenues from the execution of new contracts or the extension of existing contracts, reductions
from contracts that end or are not renewed, reductions from the early termination of contracts, and adjustments to
estimates of previously included contracts. Changes in the amount of the Company’s funded backlog and GSA
schedule contract value also are affected by the funding cycles of the government. These estimates of future
revenues are necessarily inexact and the receipt and timing of any of these revenues is subject to various
contingencies, many of which are beyond the Company’s control. The actual accrual of revenues on programs
included in backlog, funded backlog and GSA schedule contract value may never occur or may change because a
program schedule could change or the program could be canceled, a contract could be modified or canceled, an
option that the Company has assumed would be exercised is not exercised or initial estimates regarding the level
of solutions that the Company may provide could prove to be wrong. For the same reason, the Company believes
that period-to-period comparisons of backlog, funded backlog and GSA schedule contract value are not
necessarily indicative of future revenues that it may receive.

Employees

As of December 31, 2002, the Company had 4,436 employees.

Over 4,000 of the Company’s employees are technical and service professionals and managers, and over 400 are
in administrative or executive functions. Approximately 185 of the Company’s employees, all of whom are
located at NASA’s Goddard Space Flight Center, are represented by the International Brotherhood of Electrical
Workers union under a collective bargaining agreement which is due to expire in June 1, 2005. The Company has
not experienced any work stoppage or strike by these employees.

The Company believes it is successful in retaining its employees by offering competitive salary structures,
attractive incentive compensation and benefits programs, career growth opportunities, flexible work assignments
and the opportunity to perform mission-critical services, often in classified environments. The Company’s
current employees are offered an opportunity to respond to new job opportunities before the Company pursues
external recruiting. The Company considers its relations with employees to be good.

Seasonality and Cyclicality

The Company believes that its business may be subject to seasonal fluctuations. The federal government’s fiscal
year end can trigger increased purchase requests from customers for equipment and materials. Any increased
purchase requests the Company receives as a result of the federal government’s fiscal year end would serve to
increase the Company’s fourth quarter revenues but will generally decrease profit margins for that quarter, as
these activities typically are not as profitable as the Company’s normal service offerings. In addition,
expenditures by the Company’s customers tend to vary in cycles that reflect overall economic conditions as well

8

as budgeting and buying patterns. The Company’s revenue has in the past been, and may in the future be,
materially affected by a decline in the defense budget or in the economy in general. Such future declines could
alter the Company’s current or prospective customers’ spending priorities or budget cycles or extend the
Company’s sales cycle.

Corporate History

The Company is a corporation incorporated in Delaware and is the successor by merger to ManTech
International Corporation, a New Jersey corporation. As a result of the merger, the Company reincorporated from
New Jersey to Delaware and recapitalized its common stock. The Company’s predecessor corporation had three
classes of stock outstanding prior to the effective date of the merger: Class A common stock, Class B common
stock and Class C common stock, of which the Class B common stock was redeemable and, therefore, not
counted as equity for accounting purposes. On the effective date of the merger, each outstanding share of the
New Jersey corporation’s common stock was exchanged for one share of the Company’s Class A common stock
or for one share of the Company’s Class B common stock. Immediately after the merger, the Company effected a
16.3062-for-one stock split of the Company’s Class A common stock and Class B common stock. The holders of
each share of Class A common stock are entitled to one vote per share, and the holders of each share of Class B
common stock are entitled to ten votes per share. For purposes of this report, unless stated otherwise, all
references to common stock refer to shares of the Delaware corporation after giving effect to the reincorporation,
recapitalization and stock split, other than with respect to the historical consolidated financial statements.

The Company completed its initial public offering of Class A common stock on February 12, 2002, raising net
proceeds of approximately $110.2 million for the Company. The Company completed its follow-on public
offering of Class A common stock on December 20, 2002, raising net proceeds of approximately $90.9 million
for the Company. The Registrant’s Class A common stock is traded on the NASDAQ Stock Market’s National
Market under the symbol “MANT”.

Competition

The Company believes that the major competitive factors in its market are distinctive technical competencies,
intelligence and military work experience, price of services, successful past contract performance, reputation for
quality and key management with domain expertise. The Company’s key competitors currently include divisions
of large defense contractors, such as BAE SYSTEMS, plc, Lockheed Martin Corporation, Northrop Grumman
Corporation, Raytheon Company and TRW Inc., as well as information technology service companies, such as
Affiliated Computer Systems,
Inc., Anteon International Corporation, Booz Allen & Hamilton, CACI
International, Inc., Computer Sciences Corporation, DynCorp, Electronic Data Systems Corporation, Science
Applications International Corporation, Titan Corporation, Unisys Corporation and Veridian Corporation.

Recent Developments

Acquisition of Integrated Data Systems. On February 28, 2003, the Company acquired Integrated Data
Systems (IDS), a Virginia-based software development and systems integration/networking services company
supporting national intelligence and Department of Defense customers. Under the terms of the merger agreement,
IDS became a wholly owned subsidiary of ManTech International Corporation operating under the new name
ManTech Integrated Data Systems Corporation. The Company paid $57.7 million in cash plus approximately
$5.0 million in estimated purchase price adjustments to acquire IDS. The transaction is also subject to an earnout
provision. The acquisition also provides a cash tax savings to the Company due to the deductibility of goodwill
and related intangibles of approximately $22.5 million over 15 years. The goodwill is deductible because the
shareholders of IDS made a section 338(h)(10) election under the federal Tax Code. The revenues of IDS for
calendar year 2002 were approximately $40.0 million, up from $21.0 million in 2001. The Company funded the
acquisition using proceeds from its follow-on public offering completed in December 2002. IDS delivers
technology solutions and products in four core areas: software development, systems engineering/networking,

9

information assurance, and government acquisition/procurement support software. IDS has developed secure,
advanced messaging and collaboration applications and solutions in support of a wide variety of national security
networks and systems. IDS is also one of Microsoft’s leading certified partners supporting U.S. Government
classified intelligence community programs. Many of the 230 IDS employees have military or intelligence
experience.

Acquisition of MSM Security Services, Inc. The Company acquired MSM Security Services, Inc. (MSM), a
Maryland-based provider of Personnel Security Investigation (PSI) services to the U.S. Government, effective
March 1, 2003. Under the terms of the merger agreement, MSM became a wholly owned subsidiary of ManTech
International Corporation operating under the new name ManTech MSM Security Services, Inc. The Company
paid $1.9 million in cash and the repayment at closing of existing MSM debt of $2.7 million. The purchase price
is subject to certain post-closing adjustments and also includes an earnout provision. MSM’s revenue in calendar
year 2002 was approximately $19.9 million. The Company funded this acquisition using proceeds from its
follow-on public offering completed in December 2002. MSM specializes in PSI services for the United States
Government, having completed over 250,000 background investigations since its founding in 1978. MSM
employs approximately 100 staff. MSM also developed and maintains a nationwide network of approximately
1,800 experienced contract investigators that support the company’s mission. MSM has active investigation
contracts to support the United States Customs Service, Defense Security Service (DSS), the intelligence
community, and other federal government agencies.

Company Information Available on the Internet

The Company’s internet address is www.mantech.com. The Company makes available free of charge through its
internet site, via a hyperlink to the U.S. Securities and Exchange Commission EDGAR filings web site, its annual
reports on Form 10-K; quarterly reports on Form 10-Q; current reports on Form 8-K; and any amendments to
those reports filed or furnished pursuant to the Securities Exchange Act of 1934, or the “Exchange Act,” as soon
as reasonably practicable after such material is electronically filed with, or furnished to, the U.S. Securities and
Exchange Commission.

Risks Related to The Company’s Business

The Company is dependent on contracts with the U.S. Federal Government for substantially all of its
revenues.

The Company expects that federal government contracts will continue to be the primary source of its revenues
for the foreseeable future. The Company’s revenues derived from its federal government customers, consisting
primarily of customers in the intelligence community and Department of Defense, accounted for approximately
96.3%, 96.2% and 96.1% of its revenues for 2002, 2001 and 2000, respectively. If the Company was suspended
or debarred from contracting with the federal government generally, or any significant agency in the intelligence
community or Department of Defense, if the Company’s reputation or relationship with government agencies
were impaired, or if the government otherwise ceased doing business with the Company or significantly
decreased the amount of business it does with the Company, the Company’s business, prospects, financial
condition or operating results could be materially harmed.

Federal government spending priorities may change in a manner adverse to the Company’s business.

The Company’s business depends upon continued federal government expenditures on intelligence, defense and
other programs that the Company supports. The overall U.S. defense budget declined from time to time in the
late 1980s and the early 1990s. While spending authorizations for intelligence and defense-related programs by
the government have increased in recent years, and in particular after the September 11, 2001 terrorist attacks,
future levels of expenditures and authorizations for those programs may decrease, remain constant or shift to
programs in areas where the Company does not currently provide services. A significant decline in government
expenditures, or a shift of expenditures away from programs that the Company supports, could adversely affect
the Company’s business, prospects, financial condition or operating results.

10

Federal government contracts contain provisions that are unfavorable to the Company.

Federal government contracts contain provisions and are subject to laws and regulations that give the government
rights and remedies not typically found in commercial contracts, including allowing the government to:

•

Terminate existing contracts for convenience, as well as for default;

• Reduce or modify contracts or subcontracts;

• Cancel multi-year contracts and related orders if funds for contract performance for any subsequent year

become unavailable;

• Decline to exercise an option to renew a multi-year contract;

• Claim rights in products and systems produced by the Company;

•

Suspend or debar the Company from doing business with the federal government or with a
governmental agency; and

• Control or prohibit the export of the Company’s products.

If the government terminates a contract for convenience, the Company may recover only its incurred or
committed costs, settlement expenses and profit on work completed prior to the termination. If the government
terminates a contract for default, the Company may not recover even those amounts, and instead may be liable
for excess costs incurred by the government in procuring undelivered items and services from another source. As
is common with government contractors, some of the Company’s contracts have had or are currently
experiencing performance issues. The Company has received and may in the future receive show cause or cure
notices under contracts that, if not addressed to the government’s satisfaction, could give the government the
right to terminate those contracts for default or to cease procuring the Company’s services under those contracts
in the future.

The Company must comply with complex procurement laws and regulations.

The Company must comply with and is affected by laws and regulations relating to the formation, administration
and performance of federal government contracts, which affect how it does business with its customers and may
impose added costs on its business. For example, the Company is subject to the Federal Acquisition Regulations
and all supplements, which comprehensively regulate the formation, administration and performance of federal
government contracts, and to the Truth in Negotiations Act, which requires certification and disclosure of cost
and pricing data in connection with contract negotiations. The Company’s performance under its federal
government contracts and its compliance with the terms of those contracts are subject to periodic review by the
Company’s contracting agency customers. In addition, the Company routinely conducts its own internal reviews
relating to its performance under the Company’s federal government contracts and its compliance with their
terms. From time to time, such internal reviews and reviews by government contracting agencies result in
discoveries by the Company or by the Company’s government contract customers of occurrences of non-
compliance by the Company with the terms of its contracts. If a government review or investigation uncovers
improper or illegal activities, the Company may be subject to civil or criminal penalties or administrative
sanctions, including termination of contracts, forfeiture of profits, suspension of payments, fines and suspension
or debarment from doing business with federal government agencies, and may suffer reputational harm which
could impair the Company’s ability to win awards of contracts in the future or receive renewals of existing
contracts. If the Company is subject to civil and criminal penalties and administrative sanctions or suffers
reputational harm, its business, prospects, financial condition or operating results could be materially harmed.
From time to time in the past, the Company has been subject to government investigations. Currently, it is
subject to certain government investigations. For additional information regarding these investigations, see “Item
3—Legal Proceedings.” In addition, the Company is subject to industrial security regulations of Department of
Defense and other federal agencies that are designed to safeguard against foreigners’ access to classified
information. If the Company were to come under foreign ownership, control or influence, its federal government

11

customers could terminate or decide not to renew its contracts, and it could impair the Company’s ability to
obtain new contracts. The government may reform its procurement practices or adopt new contracting rules and
regulations,
including cost accounting standards, that could be costly to satisfy or that could impair the
Company’s ability to obtain new contracts.

The Company faces competition from other firms, many of which have substantially greater resources.

The Company operates in highly competitive markets and generally encounters intense competition to win
contracts. The Company competes with many other firms, ranging from small, specialized firms to large
diversified firms, many of which have substantially greater financial, management and marketing resources than
the Company does. The Company’s competitors may be able to provide the Company’s customers with different
or greater capabilities or benefits than the Company can provide in areas such as technical qualifications, past
contract performance, geographic presence, price and the availability of key professional personnel. The
Company’s failure to compete effectively with respect to any of these or other factors could have a material
adverse effect on its business, prospects, financial condition or operating results. In addition, the Company’s
competitors also have established or may establish relationships among themselves or with third parties to
increase their ability to address the Company’s customers’ needs. Accordingly,
is possible that new
competitors or alliances among competitors may emerge.

it

The Company derives significant revenues from contracts awarded through a competitive bidding process.

The Company derives significant revenues from federal government contracts that were awarded through a
competitive bidding process. For example, after giving effect to the Company’s acquisition of ManTech Aegis
Research Corporation and ManTech CTX Corporation, in each of the past three fiscal years, nine out of the
Company’s ten largest contracts, in terms of revenues, were awarded through a competitive bidding process.
Much of the business that the Company expects to seek in the foreseeable future likely will be awarded through
competitive bidding. Competitive bidding presents a number of risks, including the:

• Need to bid on programs in advance of the completion of their design, which may result in unforeseen

technological difficulties and cost overruns;

•

Substantial cost and managerial time and effort that the Company spends to prepare bids and proposals
for contracts that may not be awarded to the Company;

• Need to accurately estimate the resources and cost structure that will be required to service any contract

the Company is awarded; and

•

Expense and delay that may arise if the Company’s competitors protest or challenge contract awards
made to the Company pursuant to competitive bidding, and the risk that any such protest or challenge
could result in the resubmission of bids on modified specifications, or in termination, reduction or
modification of the awarded contract.

The Company may not be provided the opportunity in the near term to bid on contracts that are held by other
companies and are scheduled to expire if the government determines to extend the existing contract. If the
Company is unable to win particular contracts that are awarded through the competitive bidding process, it may
not be able to operate in the market for services that are provided under those contracts for a number of years. If
the Company is unable to consistently win new contract awards over any extended period, its business and
prospects will be adversely affected.

Failure to maintain strong relationships with other contractors could result in a decline in the Company’s
revenues.

For the years ended December 31, 2002 and 2001, the Company derived 9.2% and 8.1%, respectively, of its
revenues from contracts in which it acted as a subcontractor to other contractors or to joint ventures which the

12

Company and other contractors have formed to bid on and execute particular contracts or programs. The
Company expects to continue to depend on relationships with other contractors for a portion of its revenues in the
foreseeable future. The Company’s business, prospects, financial condition or operating results could be
adversely affected if other contractors eliminate or reduce their subcontracts or joint venture relationships with
the Company, either because they choose to establish relationships with the Company’s competitors or because
they choose to directly offer services that compete with the Company’s business, or if the government terminates
or reduces these other contractors’ programs or does not award them new contracts.

The Company may not receive the full amount authorized under contracts that it has entered into and may not
accurately estimate its backlog and GSA schedule contract value.

The maximum contract value specified under a government contract that the Company enters into is not
necessarily indicative of revenues that it will realize under that contract. For example, the Company derives some
of its revenues from government contracts in which the Company is not the sole provider, meaning that the
government could turn to other companies to fulfill the contract, and from indefinite delivery, indefinite quantity
contracts, which specify a maximum but only a token minimum amount of goods or services that may be
provided under the contract. In addition, Congress often appropriates funds for a particular program on a yearly
basis, even though the contract may call for performance that is expected to take a number of years. As a result,
contracts typically are only partially funded at any point during their term, and all or some of the work to be
performed under the contracts may remain unfunded unless and until Congress makes subsequent appropriations
and the procuring agency allocates funding to the contract. Nevertheless, the Company looks at these contract
values, including values based on the assumed exercise of options relating to these contracts, in estimating the
amount of the Company’s backlog. Because the Company may not receive the full amount it expects under a
contract, the Company may not accurately estimate its backlog. Similarly, in recent years the Company has been
deriving an increasing percentage of its revenues under GSA schedule contracts. GSA schedule contracts are
procurement vehicles under which government agencies may, but are not required to, purchase professional
services or products. As a result, the Company believes that potential GSA schedule contract values are not fully
reflected in traditional backlog calculations. The Company has developed a method of calculating GSA schedule
contract value that it uses to evaluate estimates for the revenues it may receive under its GSA schedule contracts.
Although the Company believes its method of determining GSA schedule contract value is based on reasonable
estimates and assumptions, its experience with GSA schedule contracts has been limited to date. The Company is
not currently aware of other companies within the Company’s market that employ comparable methods of
determining GSA schedule contract value. Estimates of future revenues included in backlog and GSA schedule
contract value are not necessarily precise and the receipt and timing of any of these revenues are subject to
various contingencies, many of which are beyond the Company’s control. For a discussion of these contingencies
see “Item 1—Business: Backlog and GSA Schedule Contract Value.” The actual accrual of revenues on
programs included in backlog and GSA schedule contract value may never occur or may change.

The Company may not accurately estimate the expenses, time and resources necessary to satisfy its
contractual obligations.

The Company enters into three types of federal government contracts for its services: cost-plus, time-and-
materials and fixed-price. For the year ended December 31, 2002, the Company derived 38.5%, 45.1% and
16.4% of its revenues from cost-plus, time-and-materials and fixed-price contracts, respectively. For 2001, the
revenues were 35.2%, 36.2% and 28.6%, respectively. Under cost-plus contracts, the Company is reimbursed for
allowable costs and paid a fee, which may be fixed or performance-based. To the extent that the actual costs
incurred in performing a cost-plus contract are within the contract ceiling and allowable under the terms of the
contract and applicable regulations, the Company is entitled to reimbursement of its costs, plus a profit.
However, if the Company’s costs exceed the ceiling or are not allowable under the terms of the contract or
applicable regulations, it may not be able to recover those costs. Under time-and-materials contracts, the
Company is reimbursed for labor at negotiated hourly billing rates and for certain expenses. The Company
assumes financial risk on time-and-material contracts because it assumes the risk of performing those contracts at

13

negotiated hourly rates. Under fixed-price contracts, the Company performs specific tasks for a fixed price.
Compared to cost-plus contracts, fixed-price contracts generally offer higher margin opportunities, but involve
greater financial risk because the Company bears the impact of cost overruns and receives the benefit of cost
savings. The Company’s profits could be adversely affected if its costs under any of these contracts exceed the
assumptions it used in bidding for the contract. Although the Company believes that it has recorded adequate
provisions in its consolidated financial statements for losses on its contracts, as required under U.S. generally
accepted accounting principles, the Company’s contract loss provisions may not be adequate to cover all actual
losses that the Company may incur in the future.

The Company’s contracts are subject to audits and cost adjustments by the federal government.

The federal government audits and reviews the Company’s performance on contracts, pricing practices, cost
structure and compliance with applicable laws, regulations and standards. Like most
large government
contractors, the Company’s contract costs are audited and reviewed on a continual basis. Although audits have
been completed on the Company’s incurred contract costs through 2000, audits for costs incurred or work
performed after 2000 remain ongoing and, for much of the Company’s work in recent years, have not yet
commenced. In addition, non-audit reviews by the government may still be conducted on all the Company’s
government contracts. An audit of the Company’s work, including an audit of work performed by companies the
Company has acquired or may acquire, could result in a substantial adjustment to the Company’s revenues
because any costs found to be improperly allocated to a specific contract will not be reimbursed, and revenues
the Company has already recognized may need to be refunded. If a government audit uncovers improper or
illegal activities, the Company may be subject to civil and criminal penalties and administrative sanctions,
including termination of contracts, forfeiture of profits, suspension of payments, fines and suspension or
debarment from doing business with federal government agencies. In addition, the Company could suffer serious
harm to its reputation if allegations of impropriety were made against it.

The Company may be liable for systems and service failures.

The Company creates, implements and maintains information technology and technical services solutions that are
often critical to its customers’ operations, including those of federal, state and local governments. The Company
has experienced and may in the future experience some systems and service failures, schedule or delivery delays
and other problems in connection with its work. If the Company’s solutions, services, products or other
applications have significant defects or errors, are subject to delivery delays or fail to meet the Company’s
customers’ expectations, the Company may:

•

Lose revenues due to adverse customer reaction;

• Be required to provide additional services to a customer at no charge;

• Receive negative publicity, which could damage the Company’s reputation and adversely affect its

ability to attract or retain customers; or

•

Suffer claims for substantial damages against the Company.

In addition to any costs resulting from product warranties, contract performance or required corrective action,
these failures may result
in customers postponing
in increased costs or loss of revenues if they result
subsequently scheduled work or canceling or failing to renew contracts.

While many of the Company’s contracts with the federal government limit the Company’s liability for damages
that may arise from negligence in rendering services to the Company’s customers, the Company cannot be sure
that these contractual provisions will protect it from liability for damages if it is sued. Furthermore, the
Company’s errors and omissions and product liability insurance coverage may not continue to be available on
reasonable terms or in sufficient amounts to cover one or more large claims, or the insurer may disclaim
coverage as to some types of future claims. The successful assertion of any large claim against the Company

14

could seriously harm the Company’s business. Even if not successful, these claims could result in significant
legal and other costs and may be a distraction to the Company’s management. In certain new business areas,
including in the area of homeland security, the Company may not be able to obtain sufficient indemnification or
insurance and may decide not to accept or solicit business in these areas.

Security breaches in classified government systems could adversely affect the Company’s business.

Many of the programs the Company supports and systems it develops, installs and maintains involve managing
and protecting information involved in intelligence, national security and other classified government functions.
A security breach in one of these systems could cause serious harm to the Company’s business, damage its
reputation and prevent the Company from being eligible for further work on critical classified systems for federal
government customers. Losses that the Company could incur from such a security breach could exceed the policy
limits that it has for errors and omissions or product liability insurance.

The Company’s quarterly operating results may vary widely.

The Company’s quarterly revenues and operating results may fluctuate significantly in the future. A number of
factors cause the Company’s revenues, cash flow and operating results to vary from quarter to quarter, including:

•

Fluctuations in revenues earned on fixed-price contracts and contracts with a performance-based fee
structure;

• Commencement, completion or termination of contracts during any particular quarter;

• Variable purchasing patterns under government GSA schedule contracts, blanket purchase agreements

and indefinite delivery, indefinite quantity contracts;

• Changes in Presidential administrations and senior federal government officials that affect the timing of

technology procurement;

• Changes in policy or budgetary measures that adversely affect government contracts in general;

• Acquisitions of other technology service providers; and

•

Increased purchase requests from customers for equipment and materials in connection with the federal
government’s fiscal year end, which may affect the Company’s fourth quarter operating results.

Changes in the volume of services provided under existing contracts and the number of contracts commenced,
completed or terminated during any quarter may cause significant variations in the Company’s cash flow from
operations because a relatively large amount of the Company’s expenses are fixed. The Company incurs
significant operating expenses during the start-up and early stages of large contracts and typically does not
receive corresponding payments in that same quarter. The Company may also incur significant or unanticipated
expenses when contracts expire or are terminated or are not renewed. In addition, payments due to the Company
from government agencies may be delayed due to billing cycles or as a result of failures of governmental budgets
to gain Congressional and Administration approval in a timely manner.

The Company’s senior management and advisory board are important to its customer relationships.

The Company believes that its success depends in part on the continued contributions of its co-founder,
Chairman of the Board of Directors, Chief Executive Officer and President, George J. Pedersen, its Executive
Vice President, Chief Financial Officer, Treasurer and Director, John A. Moore, Jr., and other members of its
senior management and advisory board. The Company relies on its executive officers and senior management to
generate business and execute programs successfully. In addition, the relationships and reputation that members
of the Company’s management team and advisory board have established and maintain with government and
military personnel contribute to the Company’s ability to maintain good customer relations and to identify new
business opportunities. While the Company has employment agreements with some of its executive officers,

15

these agreements do not prevent them from terminating their employment. The loss of Mr. Pedersen, Mr. Moore
or any other senior management or advisory board member could impair the Company’s ability to identify and
secure new contracts and otherwise to manage the Company’s business.

The Company must recruit and retain skilled employees to succeed in its labor-intensive business.

The Company believes that an integral part of its success is its ability to provide employees who have advanced
information technology and technical services skills and who work well with the Company’s customers in a
government or defense-related environment. These employees are in great demand and are likely to remain a
limited resource in the foreseeable future. If the Company is unable to recruit and retain a sufficient number of
these employees, its ability to maintain and grow its business could be negatively impacted. In addition, some of
the Company’s contracts contain provisions requiring it to commit to staff a program with certain personnel the
customer considers key to the Company’s successful performance under the contract. In the event the Company
is unable to provide these key personnel or acceptable substitutions, the customer may terminate the contract, and
the Company may not be able to recover its costs in the event the contract is terminated.

The Company’s business is dependent upon obtaining and maintaining required security clearances.

Many of the Company’s federal government contracts require its employees to maintain various levels of
security clearances, and the Company is required to maintain certain facility security clearances complying with
Department of Defense requirements. Obtaining and maintaining security clearances for employees involves a
lengthy process, and it is difficult to identify, recruit and retain employees who already hold security clearances.
If the Company’s employees are unable to obtain or retain security clearances or if the Company’s employees
who hold security clearances terminate employment with the Company, the customer whose work requires
cleared employees could terminate the contract or decide not to renew it upon its expiration. In addition, the
Company expects that many of the contracts on which it will bid will require the Company to demonstrate its
ability to obtain facility security clearances and perform work with employees who hold specified types of
security clearances. To the extent the Company is not able to obtain facility security clearances or engage
employees with the required security clearances for a particular contract, it may not be able to bid on or win new
contracts, or effectively rebid on expiring contracts.

If the Company is unable to manage its growth, its business could be adversely affected.

Sustaining the Company’s growth has placed significant demands on its management, as well as on its
administrative, operational and financial resources. For the Company to continue to manage its growth, it must
continue to improve its operational, financial and management information systems and expand, motivate and
manage its workforce. If it is unable to successfully manage its growth without compromising its quality of
service and its profit margins, or if new systems that the Company implements to assist in managing its growth
does not produce the expected benefits, the Company’s business, prospects, financial condition or operating
results could be adversely affected.

The Company may undertake acquisitions that could increase its costs or liabilities or be disruptive.

One of the Company’s key operating strategies is to selectively pursue acquisitions. The Company has made a
number of acquisitions in the past, currently is pursuing a number of potential acquisition opportunities, and will
consider other acquisitions in the future. The Company may not be able to consummate the acquisitions it
currently is pursuing on favorable terms or at all. The Company may not be able to locate other suitable
acquisition candidates at prices it considers appropriate or finance acquisitions on terms that are satisfactory to
the Company. If the Company does identify an appropriate acquisition candidate, it may not be able to
successfully negotiate the terms of an acquisition, finance the acquisition or, if the acquisition occurs, integrate
the acquired business into its existing business. Negotiations of potential acquisitions and the integration of
acquired business operations could disrupt the Company’s business by diverting management away from day-to-

16

day operations. The proceeds the Company receives from its public offerings may not be sufficient to fund the
full cost of acquisitions that it may determine to pursue. Acquisitions of businesses or other material operations
may require additional debt or equity financing, resulting in additional leverage or dilution of ownership. The
difficulties of
integration may be increased by the necessity of coordinating geographically dispersed
organizations, integrating personnel with disparate business backgrounds and combining different corporate
cultures. The Company also may not realize cost efficiencies or synergies that it anticipated when selecting its
acquisition candidates. In addition, the Company may need to record write-downs from future impairments of
intangible assets, which could reduce its future reported earnings. At times, acquisition candidates may have
liabilities or adverse operating issues that the Company fails to discover through due diligence prior to the
acquisition.

The Company may be exposed to liabilities or losses from operations that it has discontinued.

In September 2001, the Company decided to dispose of five of its businesses, either by selling them or by
winding down their operations. For more information on these discontinued operations, please see “Item 7—
Management’s Discussion and Analysis of Financial Condition and Results of Operations: Discontinued
Operations” and note 15 to the Company’s consolidated financial statements. The Company’s consolidated
financial statements reflect, under the heading “Discontinued Operations”, the Company’s estimate of the net
losses it expected from these operations through the date it estimated they would be disposed, and all losses
expected to be realized upon the disposal of these operations.

Subsequent to the disposal of these businesses, the Company may continue to be exposed to some liabilities
arising from their prior operations. For example, the Company is involved in a lawsuit alleging that it caused or
contributed to soil and groundwater contamination. For more information on this lawsuit, see “Item 3—Legal
Proceedings.” The operations from this subsidiary,
the Company’s former environmental consulting and
remediation business, particularly the performance of environmental consulting and remediation services, may
not have been or in the future may not be conducted in compliance with environmental laws, exposing the
Company to further liability and damages for the costs of investigating and cleaning up sites of spills, disposals
or other releases of hazardous materials. The Company cannot assure you that its liability in these matters, or any
other environmental liabilities that arise in the future, will not exceed its resources or will be covered by
insurance. Even though the Company has disposed of this and the other four discontinued operations, it likely
will remain liable for any costs, damages or other liabilities imposed upon them that result from or relate to their
operations prior to the disposition.

The Company may be affected by intellectual property infringement claims.

The Company’s business operations rely extensively on procuring and deploying intellectual property. The
Company’s employees develop some of the software solutions and other forms of intellectual property that the
Company uses to provide information technology solutions to its customers, but it also licenses technology from
primary vendors. Typically, under federal government contracts, the Company’s government customers may
claim rights in the intellectual property the Company develops, making it impossible for the Company to prevent
their future use of the Company’s intellectual property. The Company is and may in the future be subject to
claims from its employees or third parties who assert that software solutions and other forms of intellectual
property that the Company used in delivering services and solutions to the Company’s customers infringe upon
intellectual property rights of such employees or third parties. If the Company’s vendors, the Company’s
employees or third parties assert claims that the Company or the Company’s customers are infringing on their
intellectual property, the Company could incur substantial costs to defend these claims. In addition, if any of
these infringement claims are ultimately successful, the Company could be required to:

• Cease selling or using products or services that incorporate the challenged software or technology;

• Obtain a license or additional licenses; or

• Redesign the Company’s products and services that rely on the challenged software or technology.

17

Covenants in the Company’s credit facility may restrict the Company’s financial and operating flexibility.

The Company’s credit facility contains covenants that limit or restrict, among other things, the Company’s ability
to borrow money outside of the amounts committed under the credit facility, make investments in certain of its
subsidiaries that are borrowers under the credit facility and designated as discontinued operations or in other
entities not listed as borrowers under the credit facility, make other restricted payments, pay dividends on the
Company’s common stock, sell or otherwise dispose of assets other than in the ordinary course of business,
merge or consolidate, or make acquisitions, in each case without the prior written consent of the Company’s
lenders. The Company’s credit facility also requires the Company to maintain specified financial covenants
relating to fixed charge coverage, interest coverage, debt coverage, and minimum consolidated net worth. The
Company’s ability to satisfy these financial ratios can be affected by events beyond its control, and the Company
cannot assure you that it will meet these ratios. For example, on two occasions in the past five years, in March
2001 and in November 2000, the Company obtained waivers for failure to maintain the required fixed charge
coverage ratio as of the end of the preceding quarters under the credit facility that was in effect at that time.
Default under the Company’s credit facility could allow the lenders to declare all amounts outstanding to be
immediately due and payable. The Company has pledged substantially all of its assets, including the stock of
certain of the Company’s subsidiaries, to secure the debt under the Company’s credit facility. If the lenders
declare amounts outstanding under the credit facility to be due, the lenders could proceed against those assets.
Any event of default, therefore, could have a material adverse effect on the Company’s business if the creditors
determine to exercise their rights. The Company also may incur future debt obligations that might subject the
Company to restrictive covenants that could affect its financial and operational flexibility, restrict the Company’s
ability to pay dividends on its common stock or subject the Company to other events of default. Any such
restrictive covenants in any future debt obligations the Company incurs could limit the Company’s ability to fund
its businesses with equity investments or intercompany advances, which would impede the Company’s ability to
operate or expand its business.

From time to time the Company may require consents or waivers from its lenders to permit actions that are
prohibited by its credit facility. If in the future the Company’s lenders refuse to provide waivers of the
Company’s credit facility’s restrictive covenants and/or financial ratios, then the Company may be in default
under its credit facility, and the Company may be prohibited from undertaking actions that are necessary or
desirable to maintain and expand its business.

The Company’s employees or subcontractors may engage in misconduct or other improper activities.

The Company is exposed to the risk that employee fraud or other misconduct could occur. In addition, from time
to time the Company enters into arrangements with subcontractors and joint venture partners to bid on and
execute particular contracts or programs and it is exposed to the risk that fraud or other misconduct or improper
activities by such persons may occur. Misconduct by employees, subcontractors or joint venture partners could
include intentional failures to comply with federal laws, federal government procurement regulations or the terms
of contracts that the Company receives and failing to disclose unauthorized or unsuccessful activities to the
Company, which could lead to civil, criminal, and/or administrative penalties (including fines, imprisonment,
suspension and/or debarment from performing federal government contracts) and reputational harm. Misconduct
by the Company’s employees, subcontractors or joint venture partners could also involve the improper collection,
handling or use of the Company’s customers’ sensitive or classified information, which could result in regulatory
sanctions and serious harm to the Company’s reputation. The Company has from time to time experienced
occurrences of misconduct and improper activities by its employees, subcontractors or joint venture partners. It is
not always possible to deter misconduct by the Company’s employees, subcontractors or joint venture partners.
Under certain circumstances, conduct of the Company’s employees can be imputed to the ManTech subsidiary
for which they work and the conduct of ManTech subsidiaries can be imputed to ManTech International
Corporation with the consequence that ManTech International Corporation could be subject to sanctions and
penalties for actions taken by its subsidiaries and/or the employees of its subsidiaries. The precautions the
Company takes to prevent and detect such activity may not be effective in controlling unknown or unmanaged

18

risks or losses and such misconduct by employees, subcontractors or joint venture partners could result in serious
civil or criminal penalties or sanctions or reputational harm to the Company.

ITEM 2. PROPERTIES

All of the Company’s facilities are leased in close proximity to its customers. Since 1992, the Company has
leased its corporate headquarters office building in Fairfax, Virginia. The Company is in the sixth year of a ten-
year lease on this facility. As of December 31, 2002, the Company leased 19 additional operating facilities
throughout the metropolitan Washington, D.C. area and 56 facilities in other parts of the United States. The
Company also has employees working at customer sites throughout the United States and in other countries.

ITEM 3. LEGAL PROCEEDINGS

On June 1, 2001, CHBP, Ltd., a customer of ManTech Environmental Corporation, the Company’s former
environmental consulting and remediation business, filed suit in the 333rd District Court of Harris County Texas
against a number of parties alleging initially a total of $2.0 million in damages, now increased to a total of
$10.0 million as set forth in the most most recent pleadings, from soil and groundwater contamination caused by
the defendants while occupying a commercial business center owned by CHBP, Ltd. On November 15, 2001,
some of the defendants in this suit filed a third-party complaint against ManTech Environmental Corporation,
alleging that services provided by the Company’s subsidiary to CHBP, Ltd. caused or contributed to the alleged
contamination of the property. On April 30, 2002, CHBP, Ltd. amended their suit to assert a direct claim against
ManTech Environmental Corporation. The Company has denied the allegations. A trial date is set for January 19,
2004. The Company believes that it has other defenses and professional liability insurance coverage, and does
not believe this litigation will have a material adverse effect on its business, prospects, financial condition or
operating results. The Company decided to discontinue the operation of the commercial business performed by
ManTech Environmental Corporation. For more information, please see “Item 7—Management’s Discussion and
Analysis of Financial Condition and Results of Operations: Discontinued Operations” and note 15 to the
Company’s consolidated financial statements.

Like most large government defense contractors, the Company’s contract costs are audited and reviewed on a
continual basis by an in-house staff of auditors from the Defense Contract Auditing Agency. In addition to these
routine audits, the Company is subject from time to time to audits and investigations by other agencies of the
federal government. These audits and investigations are conducted to determine if the Company’s performance
and administration of its government contracts are compliant with contractual requirements and applicable
the Company’s
federal statutes and regulations. An audit or investigation may result
performance and administration is compliant or, alternatively, may result
initiating
proceedings against the Company or its employees, including administrative proceedings seeking repayment of
monies, suspension and/or debarment from doing business with the federal government or a particular agency, or
civil or criminal proceedings seeking penalties and/or fines. Audits and investigations conducted by the federal
government frequently span several years. Set forth below is a description of certain government audits and
investigations to which the Company is subject, in addition to routine audits of the Company’s contract costs.

in the government

in a finding that

On August 17, 2001, the Company was served with a grand jury subpoena issued by the United States District
Court for the Eastern District of Virginia. The U.S. Attorney’s Office for the Eastern District of Virginia has
advised the Company that the investigation relates to whether the Company improperly charged a portion of its
corporate merger and acquisition-related expenses and certain expenses of its Australian-based software
consulting subsidiary (which is one of the Company’s businesses included in discontinued operations) in a
manner that would have resulted in those expenses being reimbursed by the U.S. government. As anticipated, the
Company received a second grand jury subpoena seeking documents relating to this investigation on August 2,
2002. Based on the facts known to the Company as of the date of this annual report, the Company does not
expect the consequences of this investigation to have a material adverse effect on its business, prospects,
financial condition or operating results. However, this investigation is still on-going and it is not possible to tell

19

how it may develop in the future. The Company is fully cooperating with the federal government’s investigation
of this matter.

On October 9, 2002, the Company received a document subpoena issued by the Department of Defense Office of
Inspector General. The subpoena seeks the production of certain documents concerning a Department of Defense
contract pursuant to which one of the Company’s subsidiaries, ManTech Solutions & Technologies Corporation
(“MSTC”), performed personnel security clearance background checks for the Defense Security Service.
Although the Company did not handle classified information under this contract, the terms of the contract
required MSTC to utilize personnel with appropriate security clearances. The Company believes that the
investigation relates, in part, to whether it improperly charged certain costs under the contract, as well as to the
propriety of the security clearances and credentials of certain subcontractors and employees who provided
services under the contract. After receiving this subpoena, the Company’s outside counsel and the Company’s
chief compliance officer began an investigation of MSTC regarding certain matters relevant to the subpoena. In
the course of the Company’s internal investigation, which remains in process, the Company discovered that up to
five weekly time sheets of one person who performed services under the contract and who did not possess the
proper security clearance had been manually changed after receipt of the subpoena and before they were
produced to the Department of Defense Office of Inspector General to indicate that such person did not directly
charge time to the contract. None of the changed information was entered into the Company’s official accounting
records, and, therefore, the information in the Company’s accounting system was not compromised. The
Company promptly informed the government of this development, and it terminated certain employees of MSTC
following its discovery relating to the changed time sheets. The Company notes that this development may result
in proceedings against certain current and/or former employees of MSTC and possibly MSTC itself. Based on the
facts known to the Company, the Company does not expect the consequences of the government’s investigation
to have a material adverse effect on its business, prospects, financial condition or operating results. However, this
investigation is at a preliminary stage and it is not possible to tell how it may develop in the future. For additional
information regarding the penalties to which the Company could be subject in the event the government’s
investigation results in a determination that the Company or its employees or agents acted improperly, see
“Item 1—Business: Risks Related to the Company’s Business,” the sections entitled “the Company’s employees
or subcontractors may engage in misconduct or other improper activities” and “the Company must comply with
complex procurement laws and regulations” and “the Company’s contracts are subject to audits and cost
adjustments by the federal government”.

The Company also is currently subject to an investigation by the Inspector General of the EPA originating from a
subpoena received in March of 2000 regarding the number of hours the Company charged in the performance of
a contract with the EPA. The Company does not believe that the outcome of this investigation will have a
material adverse effect on its business, prospects, financial condition or operating results. The Company is fully
cooperating with the federal government’s investigation of this matter.

In addition to the foregoing, the Company is subject to certain other legal proceedings, investigations, claims and
disputes that arise in the ordinary course of its business. Although the Company cannot predict the outcomes of
these other legal proceedings, investigations, claims and disputes, based on the information now available to it,
the Company does not believe that the ultimate resolution of these matters, either individually or in the
aggregate, will have a material adverse effect on its business, prospects, financial condition or operating results.

Low

There were nine holders of record of the Company’s Class A common stock and five holders of record of the
Company’s Class B common stock. The number of holders of record of the Company’s Class A common stock is
not representative of the number of beneficial holders due to the fact that many shares are held by depositories,
brokers or nominees.

Dividend Policy

The Company’s credit facility prohibits it from paying cash dividends to holders of its common stock. In
addition, the Company currently intends to retain any earnings for the future operation and growth of its
business. Therefore, the Company does not anticipate paying any cash dividends on its common stock in the
foreseeable future. No dividends have been declared on any class of the Company’s common stock during the
past two fiscal years. Any future dividends declared would be at the discretion of the Company’s board of
directors and would depend, among other factors, upon the Company’s results of operations, financial condition
and cash requirements and the terms of the Company’s credit facility and other financing agreements at the time
such payment is considered.

Use of Proceeds

The Company completed its initial public offering of Class A Common Stock in February, 2002, pursuant to
Form S-1 (File Nos. 333-73946 and 333-82310) under the Securities Act of 1933. Under these registration
statements, the Company registered a total of 7,200,000 shares of its Class A common stock, of which 6,866,667
shares were sold by the Company, and 333,333 shares were sold by the selling stockholder, George J. Pedersen,
who is the Company’s Chairman of the Board of Directors, Chief Executive Officer and President, and a 10% or
greater stockholder. All such shares were sold at $16.00 per share on February 7, 2002. The managing
underwriters for the offering were Jefferies & Company, Inc., Legg Mason Wood Walker, Incorporated and
BB&T Capital Markets. Pursuant to the terms of the underwriting agreement described in the registration
statements, the underwriters were entitled to elect, not later than March 9, 2002, to sell up to 1,080,000 additional
shares of the Company’s Class A common stock, of which 696,487 shares were to be sold by the Company, and
383,513 shares were to be sold by the selling stockholder if the underwriters elected to sell all the additional
shares. On February 12, 2002, the underwriters elected to sell an additional 1,080,000 shares, resulting in an
aggregate offering price of $132,480,000, of which $121,010,464 pertained to shares sold by the Company and
the remaining $11,469,536 pertained to shares sold by the selling stockholder. The total underwriting discount
was approximately $9.3 million, of which the company paid $8.5 million, and the Company incurred other
expenses (including filing, legal and accounting fees) of approximately $2.3 million, none of which were paid to
the Company’s directors or officers or their affiliates or to persons owning 10% or more of any class of the
Company’s common stock or that of the Company’s affiliates.

21

In December 2002, the Company completed a follow-on public offering of its Class A Common Stock pursuant
to Form S-1 (File No. 333-101226). Under this registration statement, the Company registered a total of
6,150,000 shares of its Class A common stock, of which 4,500,000 shares were sold by the Company, and
1,650,000 shares were sold by selling stockholders. The selling stockholders were two individuals, George J.
Pedersen who is the Company’s Chairman of the Board of Directors, Chief Executive Officer and President, and
a 10% or greater stockholder, and John A. Moore, Jr. who is the Company’s Director, Executive Vice President,
Chief Financial Officer and Treasurer. All such shares were sold at $18.00 per share on December 17, 2002. The
managing underwriters for
the offering were Jefferies/Quarterdeck, LLC, Legg Mason Wood Walker,
Incorporated, U.S. Bancorp Piper Jaffray, Adams, Harkness & Hill, Inc., and BB&T Capital Markets. Pursuant to
the terms of the underwriting agreement described in the registration statements, the underwriters were entitled to
elect, not later than January 16, 2003, to sell up to 922,500 additional shares of the Company’s Class A common
stock, of which 876,500 shares were to be sold by the Company, and 46,000 shares were to be sold by one of the
selling stockholders, Mr. Moore, if the underwriters elected to sell all the additional shares. On December 30,
2002, the underwriters elected to sell an additional 922,500 shares, resulting in an aggregate offering price of
$127,305,000, of which $96,777,000 pertained to shares sold by the Company and the remaining

approximately $6.3 million, of which the company paid $4.8 million, and the Company incurred other expenses
(including filing, legal and accounting fees) of approximately $1.0 million, none of which were paid to the
Company’s directors or officers or their affiliates or to persons owning 10% or more of any class of the
Company’s common stock or that of the Company’s affiliates.

The Company’s net proceeds from the initial and follow-on public offerings were approximately $110.2 million
and $90.9 million, respectively. Proceeds from the offerings were used to repay the principal and accrued interest
outstanding under the Company’s term loan and under its subordinated debt, to pay off all but $25.0 million of
principal owing under the Company’s revolving credit facility, to purchase Aegis Research Corporation on
August 5, 2002 for $69.4 million, to purchase CTX Corporation on December 11, 2002 for $35.8 million, to
purchase Integrated Data Systems on February 28, 2003 for $62.7 million, and to purchase MSM Security
Services, Inc. on March 1, 2003 for $4.6 million. The principal and accrued interest under the Company’s term
loan was $6.0 million, principal and accrued interest under the Company’s subordinated debt was $8.1 million,
and the principal repayment under the Company’s revolving credit facility was $17.7 million.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

The following discussion of the Company’s financial condition and results of operations should be read together
with the consolidated financial statements and the notes to those statements included elsewhere in this document.
This discussion contains forward-looking statements that
involve risks and uncertainties. This discussion
addresses only the Company’s continuing operations, except in the discussion under the heading, “Discontinued
Operations.” For more information on the Company’s discontinued operations, please see note 15 to the
Company’s consolidated financial statements.

Overview

The Company delivers a broad array of information technology and technical services solutions to U.S. federal
government customers, focusing primarily on critical national defense programs for the intelligence community
and Department of Defense. The Company designs, develops, procures,
tests and
maintains mission-critical, enterprise information technology and communication systems and intelligence
processing infrastructures for the Company’s federal government customers. The Company also provides
solutions to federal government civilian agencies, as well as to state and local governments and commercial
customers. Many of the Company’s 4,436 employees have military or intelligence experience and high level
security clearances that allows the Company to work with its customers in highly classified environments and at
front-line deployments in the United States and 34 countries globally.

implements, operates,

A substantial portion of the Company’s revenues are derived from contracts with the federal government. For the
years ended December 31, 2002 and 2001, 96.3% and 96.2%, respectively, of the Company’s revenues were
derived, either as a prime or a subcontractor, from contracts with the federal government. For the years ended
December 31, 2002 and 2001, the Company derived 86.7% and 85.1%, respectively, of the Company’s revenues
from contracts with its customers in the intelligence community and Department of Defense.

The Company’s revenues consist primarily of payments for the work of the Company’s employees and, to a
lesser extent, the pass-through of costs for material and subcontract efforts under contracts with the Company’s
customers. The Company enters into three types of federal government contracts: cost-plus, time-and-materials
and fixed-price. Under cost-plus contracts, the Company is reimbursed for allowable costs and paid a fee, which
may be fixed or performance-based. Under time-and-materials contracts, the Company is reimbursed for labor at
negotiated hourly billing rates and for certain expenses. The Company assumes financial risk on time-and-
material contracts because the Company assumes the risk of performing those contracts at negotiated hourly
rates. Under fixed-price contracts, the Company performs specific tasks for a fixed price. Compared to cost-plus
contracts, fixed-price contracts generally offer higher margin opportunities but involve greater financial risk
because the Company bears the impact of cost overruns and receives the benefit of cost savings. For the year
ended December 31, 2002, the Company derived approximately 38.5%, 45.1% and 16.4% of the Company’s
revenues from cost-plus,
time-and-materials and fixed-price contracts, respectively. For the year ended
December 31, 2001, the Company derived approximately 35.2%, 36.2% and 28.6% of the Company’s revenues
from cost-plus, time-and-materials and fixed-price contracts, respectively.

The Company recognizes revenues under cost-plus contracts as its costs are incurred and the Company includes
an estimate of applicable fees earned. The Company recognizes revenues under time-and-materials contracts by
multiplying the number of direct labor-hours expended in the performance of the contract by the contract billing
the
rates and adding other billable direct costs. For contracts that
Company recognizes the incentives when they have been earned and the Company can reasonably demonstrate
satisfaction of the performance goal or when the incentive has been awarded. The Company recognizes revenues
under fixed-price contracts using the percentage of completion method, which involves a periodic assessment of
costs incurred to date in relation to the estimated total costs at completion, or upon the delivery of specific
products or services. The Company records the cumulative effects of any revisions to the Company’s estimated

include performance-based incentives,

24

total costs and revenues in the period in which the facts requiring revisions become known. If the Company
anticipates a loss on a contract, the Company provides for the full amount of the anticipated loss at the time of
that determination.

The Company’s most significant expense is the Company’s cost of services, which consists primarily of direct
labor costs for program personnel and direct expenses incurred to complete contracts, including cost of materials
and subcontract efforts. The Company’s ability to accurately predict personnel requirements, salaries and other
costs, as well as to manage personnel levels and successfully redeploy personnel, can have a significant impact
on the Company’s cost of services. General and administrative expenses consist primarily of costs associated
with the Company’s management, finance and administrative groups; personnel training; sales and marketing
expenses, which include bid and proposal efforts; and certain occupancy, travel and other corporate costs.

Year Ended December 31, 2002 Compared to the Year Ended December 31, 2001

Revenues. Revenues increased 15.9% to $500.2 million for the year ended December 31, 2002, compared to
$431.4 million for 2001. This increase is primarily attributable to additional work under contracts that were in
existence during the prior year, and the new U.S. Army Communications-Electronics Command (CECOM)
contract. Additional work from the Department of State and the Army for secure systems and infrastructure
solutions contributed to the increased revenues. Additionally, the Company’s acquisition of Aegis Research
Corporation contributed $23.7 million to the increased revenues. The Company derived approximately 39.8% of
its revenues for the year ended December 31, 2002 from work under GSA schedule contracts, compared with
approximately 32.6% for 2001. The Company derived approximately 9.2% of its revenues for 2002 from
contracts in which it acted as a subcontractor, compared with approximately 8.1% for 2001.

Cost of services. Cost of services increased 15.3% to $407.3 million for the year ended December 31, 2002,
compared to $353.3 million for 2001. As a percentage of revenues, cost of services decreased from 81.9% to
81.4%. Direct labor costs increased by 26.8%, while other direct costs of material and subcontracts increased by
4.3% over 2001. Material and subcontract costs increased to $158.2 million for the year ended December 31,
2002, compared to $151.7 million for 2001. The increase in material and subcontract costs is primarily a result of
increased secure systems and infrastructure solutions contract work.

Gross profit. Gross profit increased 19.0% to $92.9 million for the year ended December 31, 2002, compared to
$78.1 million for 2001. Gross profit margin increased to 18.6% for the year ended December 31, 2002, compared
to 18.1% for 2001. This increase resulted from higher margins on new secure systems and infrastructure
solutions and information technology tasks, in conjunction with the Company’s improved realization of cost
efficiencies, as a greater percentage of the Company’s work is performed under GSA schedule contracts.

General and administrative. General and administrative expenses increased 15.7% to $51.8 million for the year
ended December 31, 2002, compared to $44.8 million for 2001 due to additional management personnel and
infrastructure to support the growth of the Company’s business. As a percentage of revenues, general and
administrative expenses for the year ended December 31, 2002 were 10.4%, which is consistent with the prior
year.

Depreciation and amortization. Depreciation and amortization expense has decreased 22.4% to $2.5 million for
the year ended December 31, 2002 compared to $3.3 million in 2001. While depreciation expense has increased
by $0.1 million, amortization decreased by $1.1 million as a result of the Company’s adoption of SFAS No. 142,
which discontinues the amortization of acquired goodwill.

Income from operations. Income from operations increased 28.3% to $38.5 million for the year ended
December 31, 2002, compared with $30.1 million for 2001. The increase was primarily a result of the increase in
revenues relative to the cost of services discussed above.

Income from continuing operations. Income increased 40.6% to $22.8 million for the year ended December 31,
2002, compared to $16.2 million for 2001. The increase resulted from higher operating income, reduced interest
expense and a lower effective tax rate. Comparative net interest expense decreased by 77.9% for the year ended
December 31, 2002 as a result of debt reduction and investment of the proceeds of the Company’s initial and
follow-on public offerings. The Company’s effective tax rate for the year ended December 31, 2002 was 40.7%,
compared to 42.7% for 2001, due primarily to the elimination of non-deductible goodwill amortization in current
earnings.

Year Ended December 31, 2001 Compared to the Year Ended December 31, 2000

Revenues. Revenues increased 13.9% to $431.4 million for the year ended December 31, 2001, compared to
$378.8 million for 2000. This increase is attributable primarily to additional work under contracts that were in
existence during the prior year. Additional work from the Department of State and the Army for secure systems

26

and infrastructure solutions, the Defense Security Service for information technology solutions and from the
Marine Corps for systems engineering solutions contributed significantly to the increased revenues. The
Company derived approximately 32.6% of the Company’s revenues for the year ended December 31, 2001 from
work under GSA schedule contracts, compared with approximately 29.8% for 2000. The Company derived
approximately 8.1% of its revenues for 2001 from contracts in which it acted as a subcontractor, compared with
approximately 7.8% for 2000.

Cost of services. Cost of services increased 12.0% to $353.3 million for the year ended December 31, 2001,
compared to $315.4 million for 2000. As a percentage of revenues, cost of services decreased from 83.3% to
81.9%. Direct labor costs increased by 8.5%, while other direct costs increased by 19.3% over 2000. Material and
subcontract costs increased to $151.7 million for the year ended December 31, 2001, compared to $127.2 million
for 2000. The increase arose primarily from the Company’s secure systems and infrastructure solutions work
and, to a lesser degree, the Company’s Defense Security Service information technology work.

Gross profit. Gross profit increased 23.2% to $78.1 million for the year ended December 31, 2001, compared to
$63.4 million for 2000. Gross profit margin increased to 18.1% for the year ended December 31, 2001, compared
to 16.7% for 2000. The increase resulted from higher margins on new secure systems and infrastructure and
information technology tasks, in conjunction with the Company’s improved realization of cost efficiencies, as a
greater percentage of the Company’s work was performed under GSA schedule contracts.

General and administrative. General and administrative expenses increased 7.8% to $44.8 million for the year
ended December 31, 2001, compared to $41.5 million for 2000 for additional management personnel and
infrastructure to support the growth of the Company’s business. As a percentage of revenues, general and
administrative expenses declined 0.6% over the comparable period during the prior year as a result of operating
efficiencies, such as the Company’s improved monitoring of costs.

Depreciation and amortization. Depreciation and amortization expense remained relatively constant for the years
ended December 31, 2001 and 2000, because the Company did not acquire any companies or make any
significant purchases of fixed assets during the periods.

Income from operations. Income from operations increased 61.7% to $30.1 million for the year ended
December 31, 2001, compared with $18.6 million for 2000. The increase was primarily a result of the increase in
revenues relative to the cost of services discussed above.

Income from continuing operations. Income increased 127.9% to $16.2 million for the year ended December 31,
2001, compared to $7.1 million for 2000. The increase resulted from higher operating income, an increase in
other income, reduced interest expense and a lower effective tax rate. Other income increases are primarily
attributable to the Company’s equity investment in an affiliate which was more profitable in 2001. Interest
expense for 2001 decreased by 34.2% from the year ended December 31, 2000 as a result of a $6.2 million
reduction in the Company’s average balance under the Company’s line of credit and from lower interest rates.
The Company’s effective tax rate for the year ended December 31, 2001 was 42.7%, compared to 45.6% for
2000, due to a relative decrease in non-deductible expenses.

Liquidity and Capital Resources

The Company’s primary source of liquidity is cash provided by operations and the Company’s revolving credit
and term-loan facility. The Company funds its operations primarily through cash provided by operating activities.
Net proceeds of $201.1 million from the Company’s initial and follow-on public offerings also provide a source
of liquidity. Cash provided by operating activities of continuing operations was $7.4 million for the year ended
December 31, 2002, a decrease of $11.6 million from the prior year. The primary reasons for this decrease were
increased contract receivables and decreased tax accruals offset by an increase in income from continuing
operations and an increase in billings in excess of revenue earned. Cash paid for income taxes for the year ended
December 31, 2002 includes $5.4 million associated with the Company’s conversion to an accrual-basis
taxpayer.

27

Cash provided by operating activities of continuing operations for 2002, 2001 and 2000 was $7.4 million,
$19.0 million and $19.9 million, respectively. In 2002, cash provided by operating activities was generated
primarily from income from continuing operations of $22.8 million and increases in accounts payable and
accruals, offset by an increase in contract receivables and a decrease in deferred income taxes. In 2001, cash
provided by operating activities was generated primarily from income from continuing operations of
$16.2 million and increases in accounts payable and accruals, offset by an increase in contract receivables and
decreases in billings in excess. In 2000, cash provided by operating activities was generated primarily from
income from continuing operations of $7.1 million, a decrease in contract receivables, an increase in billings in
excess and an increase in salary-related accruals, offset by increases in prepaid expenses and other assets and
decreases in accounts payable and accrued expenses.

Cash used in investing activities of continuing operations was $108.2 million for the year ended December 31,
2002, compared to $5.8 million for the prior year. Investing activities included the acquisitions of Aegis
Research Corporation and CTX Corporation for $69.4 million and $35.8 million, respectively, purchases of
property and equipment of $2.7 million, and investments in intellectual property of $1.3 million. Cash used in
investing activities for 2001 and 2000 was $5.8 million and $4.2 million, respectively. Investing activities have
primarily consisted of investments in intellectual property, acquisitions of businesses, investments and loans to
affiliates and purchases of property and equipment.

Cash provided by financing activities of continuing operations was $155.1 million for the year ended
December 31, 2002, compared to cash used of $4.8 million and $0.0 million for the years ended December 31,
2001 and 2000, respectively. The net cash provided by financing activities during 2002 is primarily the result of
the net proceeds of the Company’s initial and follow-on public offerings of $110.2 million and $90.9 million,
respectively, less amounts used to repay debt. The net cash used during 2001 is primarily the result of debt
reduction. Debt repayments and borrowings produced no significant cash impact in 2000.

On August 5, 2002, the Company acquired all of the outstanding shares of Aegis Research Corporation for a cash
purchase price of approximately $69.1 million, excluding $0.3 million of acquisition-related costs. The
acquisition has been accounted for using the purchase method of accounting. The purchase price has been
allocated to the assets acquired and the liabilities assumed based upon their estimated fair market values. The
balance of the purchase price was recorded as goodwill. The acquisition of Aegis Research Corporation also
provides a cash tax savings to the Company due to the deductibility of goodwill and related intangibles of
approximately $24.4 million over 15 years. The goodwill is deductible because the shareholders of Aegis
Research Corporation made a section 338(h)(10) election under the federal Tax Code. The revenues of Aegis
Research Corporation for calendar year 2002 were $57.1 million, of which $23.7 million were consolidated into
the Company’s revenues in calendar year 2002. The Company funded the acquisition using proceeds from the
Company’s initial public offering.

On December 11, 2002, the Company acquired all of the outstanding shares of CTX Corporation for a cash
purchase price of approximately $35.3 million, excluding $0.5 million of acquisition-related costs. The
acquisition has been accounted for using the purchase method of accounting. The purchase price has been
allocated to the assets acquired and the liabilities assumed based upon their estimated fair market values. The
balance of the purchase price was recorded as goodwill. The acquisition of CTX Corporation also provides a cash
tax savings to the Company due to the deductibility of goodwill and related intangibles of approximately
$10.5 million over 15 years. The goodwill is deductible because the shareholders of CTX Corporation made a
section 338(h)(10) election under the federal Tax Code. The revenues of CTX Corporation for calendar year
2002 were $35.0 million, of which $1.6 million were consolidated into the Company’s revenues in calendar year
2002. The Company funded the acquisition using proceeds from the Company’s initial and follow-on public
offerings.

On December 17, 2001, the Company executed a new Business Loan and Security Agreement with Citizens
Bank of Pennsylvania, PNC Bank N.A., Branch Banking and Trust Company of Virginia, and Chevy Chase
Bank, F.S.B. to refinance and replace a prior loan agreement. The agreement provides for a $65.0 million

28

revolving credit facility and a $6.4 million term loan. Under the term-loan portion of the agreement, the principal
balance was payable in consecutive quarterly installments of $0.5 million on the last business day of each quarter
commencing with the last business day of December 2001. The maturity date of the agreement is December 31,
2004. Under the agreement, the Company is required to maintain specified financial covenants relating to fixed
charge coverage, interest coverage, debt coverage, and to maintain a certain level of consolidated net worth. The
agreement also places limitations on additional borrowings, mergers, and related party transactions, issuances of
capital stock and payment of dividends, and limitations with respect to capital expenditures. Borrowings under
the agreement are collateralized by the Company’s eligible contract receivables, inventory, all of the Company’s
stock in certain of the Company’s subsidiaries and certain property and equipment and bear interest at the
London Interbank Offered Rate (LIBOR), or the lender’s prime rate, plus market-rate spreads that are determined
based on a company leverage ratio calculation. The LIBOR spreads may range from 1.00% to 1.75% and the
prime rate spreads may range from 0.00% to 0.50%. To manage the Company’s exposure to the fluctuations in
these variable interest rates, an interest swap was executed in December 2001. The swap agreement has a
notional principal amount of $25.0 million and currently has a fixed LIBOR rate of 6.83%. The term loan balance
and accrued interest and all but $25.0 million of the revolving credit facility were repaid during the first quarter
of 2002. At December 31, 2002, the Company had $25.0 million in borrowings outstanding under the revolving
credit facility under the agreement.

In January 1998, the Company executed a seven-year Subordinated Credit Agreement with First Source Financial
LLP for $8.0 million to finance the redemption of the Company’s preferred stock. The principal balance was
payable in eight consecutive quarterly installments of $0.9 million on the first business day of each quarter
commencing with the first business day of January 2003. A ninth and final payment was due on the last day of
December 2004. The balance and accrued interest of this credit facility was repaid during the first quarter of
2002.

The Company believes the capital resources available to it under the Company’s credit agreements and cash from
the Company’s operations are adequate to fund the Company’s ongoing operations and to support the internal
growth the Company expects to achieve for at least the next 12 months. The Company anticipates financing its
external growth from acquisitions as well as the Company’s longer-term internal growth through one or a
combination of the following: cash from operations; additional borrowing; issuance of equity; use of the existing
revolving facility; or a refinancing of the Company’s credit facilities.

Discontinued Operations

In September 2001, the Company decided to exit certain lines of business involving foreign operations or
operations that primarily serve commercial customers. The Company decided to dispose of the Company’s
Australia-based software solutions consulting business, the Company’s United Kingdom-based bank remittance
processing business, the Company’s China-based consulting business, the Company’s U.S.-based environmental
consulting and remediation business and the Company’s U.S.-based application-hosting business. The Company
is not discontinuing or disposing of the Company’s operations that currently provide comprehensive information
technology and systems engineering solutions to federal government agencies, including the EPA, or that
currently provide database conversion solutions to commercial customers. The lines of business to be disposed of
or discontinued have been classified as discontinued operations in the Company’s consolidated financial
statements and the likely net gains and losses to income expected from these businesses through the estimated
date of disposal have been accrued in accordance with Accounting Principles Board Opinion No. 30, Reporting
the Results of Operations—Reporting the Effects of Disposal of a Segment of a Business and Extraordinary
Unusual and Infrequently Occurring Events and Transactions. The Company has concluded the disposal of all of
these businesses as of December 31, 2002, except the Company’s Australia-based software solutions business.
As of December 31, 2002, the Company reached a definitive agreement regarding the sale of this business, and
the transaction closed in February 2003. Additional accruals for losses incurred in connection with the disposal
of discontinued operations of $0.8 million and $2.9 million were recorded in the second and fourth quarters of
2002, respectively. See “Item 1—Business: Risks Related to the Company’s Business,” the section entitled, “The
Company may be exposed to liabilities or losses from operations that the Company has discontinued.”

Critical Accounting Estimates and Policies

Critical accounting policies are defined as those that are reflective of significant judgments and uncertainties, and
potentially result in materially different results under different assumptions and conditions. Application of these
policies is particularly important to the portrayal of the Company’s financial condition and results of operations.
The discussion and analysis of the Company’s financial condition and results of operations are based on the
Company’s consolidated financial statements, which have been prepared in accordance with accounting
principles generally accepted in the United States of America. The preparation of these consolidated financial
statements requires management to make estimates and judgments that affect the reported amount of assets,
liabilities, revenues and expenses. Actual results may differ from these estimates under different assumptions or
conditions.

Revenue Recognition and Cost Estimation

The Company recognizes revenue when persuasive evidence of an arrangement exists, services have been
rendered, the contract price is fixed or determinable, and collectibility is reasonably assured. The Company has a
standard internal process that it uses to determine whether all required criteria for revenue recognition have been
met. This standard internal process includes a monthly review of contract revenues and expenses by several
levels of management. This review covers, among other matters, progress against schedule, project staffing and
levels of effort, risks and issues, subcontract management, incurred and estimated costs, and disposition of prior
action items. This monthly internal review is designed to determine whether the overall progress on a contract is
consistent with the effort expended and revenue recognized to date.

The Company’s revenues consist primarily of payments for the work of the Company’s employees, and to a
lesser extent, the pass through of costs for materials and subcontract efforts under contracts with the Company’s
customers. Cost of services consists primarily of compensation expenses for program personnel, the fringe
benefits associated with this compensation, and other direct expenses incurred to complete programs, including
cost of materials and subcontract efforts.

The majority of the Company’s revenues are derived from cost-plus-fixed-fee, cost-plus-award-fee, firm-fixed-
price, or time-and-materials contracts. Absent evidence to the contrary, the Company recognizes revenue as
follows. Under cost-plus-fixed or award-fee contracts, revenues are recognized as costs are incurred and include
an estimate of applicable fees earned. Under firm-fixed-price contracts, revenues are estimated on the percentage
of completion method, on the basis of costs incurred in relation to estimated total costs, or upon delivery of
specific products or services, as appropriate. For time-and-material contracts, revenues are computed by
multiplying the number of direct labor-hours expended in the performance of the contract by the contract billing
rates and adding other billable direct costs. Performance incentives are incorporated in certain contracts, which
provide increased and decreased revenues based on actual performance compared to established targets.
Incentives based upon cost performance are recorded when earned and other incentives and awards are recorded
when the amounts are earned and can be reasonably determined, or are awarded. In certain circumstances,
revenues are recognized when contract amendments have not been finalized. Prior to agreeing to commence
work directed by the customer and before receipt of the written modification or amendment to the existing
contract,
the Company requires the completion of an internal memo that assesses the probability of the
modification being executed in a timely fashion and the Company’s ability to subsequently collect payment from
the customer.

Contract revenue recognition inherently involves estimation. Examples of estimates include the contemplated
level of effort to accomplish the tasks under contract, the cost of the effort, and an ongoing assessment of the
Company’s progress toward completing the contract. From time to time, as part of the Company’s standard
management processes, facts develop that require the Company to revise its estimated total costs or revenues. In
most cases, these revisions relate to changes in the contractual scope of the Company’s work. To the extent that a
revised estimate affects contract profit or revenue previously recognized, the Company records the cumulative
effect of the revision in the period in which the facts requiring the revision become known. Anticipated losses are
recognized in the accounting period in which they are first determined.

30

Goodwill

Goodwill represents the excess of cost over the fair value of net tangible and identifiable intangible assets of
acquired companies. Effective January 1, 2002, the Company adopted SFAS No. 142, and no longer amortizes
goodwill, but rather goodwill is to be reviewed at least annually for impairment. The Company has elected to
perform this review annually on June 30 of each calendar year. For acquisitions completed prior to the adoption
of SFAS No. 141 and SFAS No. 142 on January 1, 2002, goodwill was amortized on a straight-line basis over
periods ranging from two to twenty years.

Discontinued Operations

In September 2001, the Company executed a formal plan to exit certain commercial and foreign lines of business
that no longer contribute to the Company’s core competencies. Based on independent valuations, market
comparable information and interest expressed in these businesses, an estimate has been provided for the likely
net gains and losses to income expected from these businesses through the estimated dates of disposal. As a
result, in accordance with APB Opinion No. 30, Reporting the Results of Operations—Reporting the Effects of
Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and
Transactions, results of operations have been classified as discontinued and prior periods have been restated. The
Company has segregated the net assets and liabilities held for sale, recorded all current and expected future losses
and deferred all gains expected to be realized upon disposal of the respective entities. The amounts the Company
will ultimately realize could differ in the near term from the amounts estimated in arriving at the loss on disposal
of the discontinued operations.

The Company’s significant accounting policies, including the critical policies listed above, are described in the
notes to the consolidated financial statements included in this report.

Accounting Pronouncements

Effective January 1, 2002, the Company adopted SFAS No. 144, Accounting for the Impairment or Disposal of
Long-Lived Assets, which replaces SFAS No. 121. SFAS No. 144 requires that long-lived assets be measured at
the lower of carrying amount or fair value less cost to sell, whether reported in continuing operations or in
discontinued operations. SFAS No. 144 also broadens the reporting of discontinued operations to include all
components of an entity with operations that can be distinguished from the rest of the entity and that will be
eliminated from the ongoing operations of the entity in a disposal transaction. The adoption of this new
pronouncement had no impact on the consolidated financial statements.

the Company adopted EITF 01-14,

Income Statement Characterization of
Effective January 1, 2002,
Reimbursements Received for “Out-of-Pocket” Expenses Incurred. EITF 01-14 requires that companies report
reimbursements received for out-of-pocket expenses incurred as revenue, rather than as a reduction of expenses.
As the Company has historically accounted for reimbursements for out-of-pocket expenses in the manner
provided for under EITF 01-14, the adoption of the provisions of EITF 01-14 did not have an impact on the
Company’s consolidated financial position or results of operations.

In April 2002, the FASB issued SFAS No. 145, Rescission of FASB Statements No. 4, 44 and 64, Amendment of
FASB Statement No. 13 and Technical Corrections. Among other things, SFAS 145 rescinds both SFAS 4,
Reporting Gains and Losses from Extinguishment of Debt, and the amendment
to SFAS 4, SFAS 64,
Extinguishments of Debt Made to Satisfy Sinking Fund Requirements. Through this rescission, SFAS 145
eliminates the requirement that gains and losses from the extinguishment of debt be aggregated and, if material,
classified as an extraordinary item, net of the related income tax effect. Generally, SFAS 145 is effective for
transactions occurring after May 15, 2002. The Company does not believe that SFAS 145 will have a material
impact on its future earnings or financial position.

31

In June 2002, the FASB issued SFAS No. 146, Accounting for Costs Associated with Exit or Disposal Activities.
SFAS No. 146 nullifies Emerging Issues Task Force Issue No. 94-3, Liability Recognition for Certain Employee
Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring).
This statement requires that an exit or disposal activity related cost be recognized when the liability is incurred
instead of when an entity commits to an exit plan. The provisions of SFAS No. 146 are effective for financial
transactions initiated after December 31, 2002. The Company does not believe that SFAS 146 will have a
material impact on its future earnings or financial position.

the FASB issued Interpretation No. 45, Guarantor’s Accounting and Disclosure
In November 2002,
Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others, an interpretation of
FASB Statements No. 5, 57 and 107 and rescission of FASB Interpretation No. 34. FIN 45 elaborates on the
disclosures to be made by a guarantor in its interim and annual financial statements about its obligations under
guarantees issued. FIN 45 also clarifies that a guarantor is required to recognize, at the inception of a guarantee, a
liability for the fair value of the obligation undertaken. The initial recognition and measurement provisions of
FIN 45 are effective for guarantees issued or modified after December 31, 2002. Accounting for guarantees
issued prior to this date is unaffected by FIN 45.

In December 2002, the FASB issued SFAS No. 148, Accounting for Stock-based Compensation—Transition and
Disclosure, an amendment of SFAS No. 123. SFAS No. 148 provides alternative methods of transition for a
voluntary change to the fair value based method of accounting for stock-based employee compensation. In
addition, SFAS No. 148 amends the disclosure requirements of SFAS No. 123 to require more prominent and
more frequent disclosures in financial statements about the effects of stock-based compensation. This statement
is effective for fiscal years ending after December 15, 2002. The Company does not believe that SFAS No. 148
will have a material impact on the Company’s future earnings or financial position.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

The Company’s exposure to market risk relates to changes in interest rates for borrowings under the Company’s
senior term loan and the Company’s revolving credit facility. These borrowings bear interest at variable rates.
During the first quarter of 2002, the Company repaid all but $25.0 million in borrowings outstanding under the
Company’s revolving credit facility. A hypothetical 10% increase in interest rates would have increased the
Company’s annual interest expense for the year ended December 31, 2002 by less than $0.1 million.

In December 2001, the Company entered into an interest swap agreement in order to reduce the Company’s
exposure associated with the market volatility of fixed LIBOR interest rates. This agreement has a notional
principal amount of $25.0 million and, as of December 31, 2002, had a rate of 6.83%. This agreement is a hedge
against revolving debt of $25.0 million, which bears interest at monthly floating LIBOR plus 1.00%. At stated
monthly intervals the difference between the interest on the floating LIBOR-based debt and the interest
calculated in the swap agreement are settled in cash. The value of the swap at December 31, 2002 was a negative
$3.3 million.

The Company does not use derivative financial instruments for speculative or trading purposes. The Company
invests its excess cash in short-term, investment grade, interest-bearing securities.

The Company’s investments are made in accordance with an investment policy approved by the board of
directors. Under this policy, no investment securities can have maturities exceeding one year and the average
maturity of the portfolio cannot exceed 90 days.

December 31, 2002. These financial statements are the responsibility of the Company’s management. Our
responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States of
America. Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial
position of ManTech International Corporation and subsidiaries at December 31, 2002 and 2001, and the results
of their operations and their cash flows for each of the three years in the period ended December 31, 2002 in

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Years Ended December 31, 2002, 2001 and 2000

1. Description of the Business

ManTech International Corporation delivers a broad array of information technology and technical services
solutions to U.S. federal government customers, focusing primarily on critical national defense programs for the
intelligence community and Department of Defense. The Company designs, develops, procures, implements,
operates, tests and maintains mission-critical, enterprise information technology and communication systems and
infrastructures for the Company’s federal government customers in the United States and 34 countries
worldwide.

2. Summary of Significant Accounting Policies

Principles of Consolidation—The accompanying consolidated financial statements include the accounts of
ManTech International Corporation and its majority-owned subsidiaries (the Company). Minority interest
represents minority stockholders’ proportionate share of the equity in one of the Company’s consolidated
subsidiaries. The Company’s share of affiliates’ earnings (losses) is included in the consolidated statements of
income using the equity method. All intercompany accounts and transactions have been eliminated.

Use of Accounting Estimates—The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date
of the financial statements and the reported amounts of revenues and expenses during the reporting period. These
estimates involve judgments with respect to, among other things, various future economic factors that are
difficult to predict and are beyond the control of the Company. Therefore, actual amounts could differ from these
estimates.

Revenue Recognition—The majority of the Company’s revenues are derived from cost-plus-fixed-fee, cost-plus-
award-fee, firm-fixed-price, or time-and-materials contracts. Under cost-plus-fixed or award-fee contracts,
revenues are recognized as costs are incurred and include an estimate of applicable fees earned. Under firm-
fixed-price contracts, revenues are estimated on the percentage of completion method, on the basis of costs
incurred in relation to estimated total costs, or upon delivery of specific products or services, as appropriate. For
time-and-material contracts, revenues are computed by multiplying the number of direct labor-hours expended in
the performance of the contract by the contract billing rates and adding other billable direct costs. Performance
incentives are incorporated in certain contracts, which provide increased and decreased revenues based on actual
performance compared to established targets. Incentives based upon cost performance are recorded when earned
and other incentives and awards are recorded when the amounts are earned and can be reasonably determined, or
are awarded. In certain circumstances, revenues are recognized when contract amendments have not been
finalized. Prior to agreeing to commence work directed by the customer and before receipt of the written
modification or amendment to the existing contract, the Company requires the completion of an internal memo
that assesses the probability of the modification being executed in a timely fashion and the Company’s ability to
subsequently collect payment from the customer. Anticipated losses are recognized in the accounting period in
which they are first determined.

Cost of Services—Cost of services consists primarily of compensation expenses for program personnel and direct
expenses incurred to complete programs, including cost of materials and subcontract efforts.

Cash and Cash Equivalents—For the purpose of reporting cash flows, cash and cash equivalents include cash on
hand, amounts due from banks, and short-term investments with maturity dates of three months or less at the date
of purchase.

41

Property and Equipment—Property and equipment are recorded at original cost. Upon sale or retirement, the
costs and related accumulated depreciation or amortization are eliminated from the respective accounts and any
resulting gain or loss is included in income. Maintenance and repairs are charged to expense as incurred.

Depreciation and Amortization—Furniture and office equipment are depreciated using the straight-line method
with estimated useful lives ranging from five to fifteen years. Leasehold improvements are amortized using the
straight-line method over a life of five years, or the term of the lease, whichever is shorter.

Inventory—Inventory is carried at the lower of cost or market. Cost is computed on a specific identification
basis.

Goodwill and Other Intangibles—Goodwill represents the excess of cost over the fair value of net tangible and
identifiable intangible assets of acquired companies. Contract rights and other intangibles are amortized on a
straight-line basis over periods ranging from three to eight years.

Software Development Costs—The Company accounts for software development costs in accordance with
Statement of Financial Accounting Standards (SFAS) No. 86, Accounting for the Costs of Computer Software to
be Sold, Leased, or Otherwise Marketed. For projects fully funded by the Company, significant development
costs are capitalized from the point of demonstrated technological feasibility until the point in time that the
product is available for general release to customers. Once the product is available for general release, capitalized
costs are amortized on a straight-line basis over a five-year period or other such shorter period as may be
required. The Company recorded $841,000, $690,000, and $665,000 of amortization expense for the years ended
December 31, 2002, 2001 and 2000, respectively. Capitalized software costs included in other intangibles at
December 31, 2002 and 2001, were $3,722,000 and $2,759,000, respectively.

Employee Supplemental Savings Plan (ESSP) Assets—The Company maintains several non-qualified defined
contribution supplemental retirement plans for certain key employees that are accounted for in accordance with
Emerging Issues Task Force (EITF) Issue 97-14, Accounting for Deferred Compensation Arrangements Where
Amounts Earned Are Held in a Rabbi Trust and Invested, as the underlying assets are held in rabbi trusts with
investments directed by the respective employee. A rabbi trust is a grantor trust generally set up to fund
compensation for a select group of management and the assets of this trust are available to satisfy the claims of
general creditors in the event of bankruptcy of the Company. As required by EITF 97-14, the assets held by the
rabbi trusts are recorded at fair value in the consolidated financial statements as Employee Supplemental Savings
Plan Assets with a corresponding amount recorded as a deferred compensation liability in Accrued Retirement.

Impairment of Long-Lived Assets—Whenever events or changes in circumstances indicate that the carrying
amount of long-lived assets, including goodwill, software development costs and other intangibles, may not be
fully recoverable, the Company evaluates the probability that future undiscounted net cash flows, without interest
charges, will be less than the carrying amount of the assets. If any impairment were indicated as a result of this
review, the Company would recognize a loss based on the amount by which the carrying amount exceeds the
estimated discounted future cash flows. The Company believes that no impairments exist as of December 31,
2002.

Income Taxes—Deferred income taxes are recognized based on the estimated future tax effects of temporary
differences between the carrying amounts of assets and liabilities for financial reporting purposes and the
amounts used for income tax purposes. Valuation allowances are established when necessary to reduce deferred
tax assets to amounts expected to be realized. Income tax expense represents the current tax provision for the
period and the change during the period in deferred tax assets and liabilities. No provision is made for U.S. taxes
on foreign subsidiaries where earnings are expected to be reinvested indefinitely.

Foreign Currency Translation—All assets and liabilities of foreign subsidiaries are translated into U.S. dollars
at fiscal year-end exchange rates. Income and expense items are translated at average monthly exchange rates

42

prevailing during the fiscal year. The resulting translation adjustments are recorded as a component of
Accumulated other comprehensive income (loss).

Comprehensive Income (Loss)—Comprehensive income (loss) consists of net income (loss), unrealized gains or
losses on the Company’s cash flow hedge, and foreign currency translation adjustments and is presented in the
Consolidated Statements of Changes in Stockholders’ Equity.

Stock-Based Compensation—As permitted under SFAS No. 123, Accounting for Stock-Based Compensation, the
Company accounts for stock-based compensation plans using the intrinsic value method under the recognition
and measurement principles of Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued
to Employees and related Interpretations. No stock-based employee compensation cost is reflected in the net
income, as all options granted under those plans had an exercise price equal to the market value of the underlying
common stock on the date of grant. In accordance with the provisions of SFAS No. 148, Accounting for Stock-
Based Compensation – Transition and Disclosure, the following table illustrates the effect on net income and
earnings per share if the Company had applied the fair value recognition provisions of SFAS No. 123 to stock-
based employee compensation (in thousands).

For disclosure purposes, the fair value of each option is estimated on the date of grant using the Black-Scholes
(Minimum Value) option-price model. Assumptions used in computing the pro forma effect of stock-based
compensation are presented in note 10.

Fair Value of Financial Instruments—The carrying value of the Company’s cash and cash equivalents,
accounts receivable, accounts payable and accrued expenses approximate their fair values.

New Accounting Pronouncements—Effective January 1, 2002,
the Company adopted SFAS No. 144,
Accounting for the Impairment or Disposal of Long-Lived Assets, which replaces SFAS No. 121. SFAS No. 144
requires that long-lived assets be measured at the lower of carrying amount or fair value less cost to sell, whether
reported in continuing operations or in discontinued operations. SFAS No. 144 also broadens the reporting of
discontinued operations to include all components of an entity with operations that can be distinguished from the
rest of the entity and that will be eliminated from the ongoing operations of the entity in a disposal transaction.
The adoption of this new pronouncement had no impact on the consolidated financial statements.

the Company adopted EITF 01-14,

Income Statement Characterization of
Effective January 1, 2002,
Reimbursements Received for “Out-of-Pocket” Expenses Incurred. EITF 01-14 requires that companies report
reimbursements received for out-of-pocket expenses incurred as revenue, rather than as a reduction of expenses.
As the Company has historically accounted for reimbursements for out-of-pocket expenses in the manner
provided for under EITF 01-14, the adoption of the provisions of EITF 01-14 did not have an impact on the
Company’s consolidated financial position or results of operations.

In April 2002, the FASB issued SFAS No. 145, Rescission of FASB Statements No. 4, 44 and 64, Amendment of
FASB Statement No. 13 and Technical Corrections. Among other things, SFAS 145 rescinds both SFAS 4,
Reporting Gains and Losses from Extinguishment of Debt, and the amendment
to SFAS 4, SFAS 64,
Extinguishments of Debt Made to Satisfy Sinking Fund Requirements. Through this rescission, SFAS 145
eliminates the requirement that gains and losses from the extinguishment of debt be aggregated and, if material,
classified as an extraordinary item, net of the related income tax effect. Generally, SFAS 145 is effective for
transactions occurring after May 15, 2002. The Company does not believe SFAS 145 will have a material impact
on its future earnings or financial position.

In June 2002, the FASB issued SFAS No. 146, Accounting for Costs Associated with Exit or Disposal Activities.
SFAS No. 146 nullifies Emerging Issues Task Force Issue No. 94-3, Liability Recognition for Certain Employee
Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring).
This statement requires that an exit or disposal activity related cost be recognized when the liability is incurred
instead of when an entity commits to an exit plan. The provisions of SFAS No. 146 are effective for financial
transactions initiated after December 31, 2002. The Company does not believe SFAS 146 will have a material
impact on its future earnings or financial position.

the FASB issued Interpretation No. 45, Guarantor’s Accounting and Disclosure
In November 2002,
Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others, an interpretation of
FASB Statements No. 5, 57 and 107 and rescission of FASB Interpretation No. 34. FIN 45 elaborates on the
disclosures to be made by a guarantor in its interim and annual financial statements about its obligations under
guarantees issued. FIN 45 also clarifies that a guarantor is required to recognize, at the inception of a guarantee, a
liability for the fair value of the obligation undertaken. The initial recognition and measurement provisions of
FIN 45 are effective for guarantees issued or modified after December 31, 2002. Accounting for guarantees
issued prior to this date is unaffected by FIN 45.

In December 2002, the FASB issued SFAS No. 148, Accounting for Stock-based Compensation—Transition and
Disclosure, an amendment of SFAS No. 123. SFAS No. 148 provides alternative methods of transition for a
voluntary change to the fair value based method of accounting for stock-based employee compensation. In
addition, SFAS No. 148 amends the disclosure requirements of SFAS No. 123 to require more prominent and
more frequent disclosures in financial statements about the effects of stock-based compensation. This statement
is effective for fiscal years ending after December 15, 2002. The Company does not believe that the adoption of
SFAS No. 148 will have a material effect on its future earnings or financial position.

Reclassifications—Certain reclassifications have been made to previously reported balances to conform to the
current-period presentation.

3. Earnings per Share

Basic earnings per share has been computed by dividing net income available to common stockholders by the
weighted average number of shares of Class A, Class B and Class C common stock outstanding during each
period. Shares issued during the period and shares reacquired during the period are weighted for the portion of
the period that they were outstanding. Diluted earnings per share have been computed in a manner consistent
with that of basic earnings per share while giving effect to all potentially dilutive common shares that were
outstanding during each period. In conjunction with the Company’s Initial Public Offering, in January 2002 the
Company effected a 16.3062- for-one stock split (see note 10). For periods prior to the effective date of the stock
split, outstanding shares and per share data contained in these financial statements has been restated to reflect the
impact of the stock split. The weighted average number of common shares outstanding is computed as follows:

4. Business Segment and Geographic Area Information

The Company operates as one segment, delivering a broad array of information technology and technical services
solutions under contracts with the U.S. Government, state and local governments, and commercial customers.
The Company’s federal government customers typically exercise independent contracting authority, and even
offices or divisions within an agency or department may directly, or through a prime contractor, use the
Company’s services as a separate customer so long as that customer has independent decision-making and
contracting authority within its organization. No single customer accounted for 10% or more of the Company’s
accounts receivable or revenues as of or for the years ended December 31, 2002, 2001 and 2000. In addition,
there were no sales to any customers within a single country except for the United States where the sales
accounted for 10% or more of total revenue. The Company treats sales to U.S. Government customers as sales
within the United States regardless of where the services are performed. Substantially all assets of continuing
operations were held in the United States for the years ended December 31, 2002, 2001 and 2000. Revenues by
geographic customer and the related percentages of total revenues for the years ended December 31, 2002, 2001
and 2000, were as follows (in thousands):

actual rates less a reduction of 0.5% of the actual general and administrative rate base before a Defense Contract
Audit Agency (DCAA) audit is completed. The balance remaining, as well as any retainage, is billable upon
completion of a DCAA audit (see note 13). Revenues recorded in excess of contract value or funding are billable
upon receipt of contractual amendments. Amounts currently billable consist principally of amounts to be billed
within the next month.

7. Goodwill and Other Intangibles

Effective January 1, 2002, the Company adopted SFAS No. 142, Goodwill and Other Intangible Assets. SFAS
142 requires, among other things, the discontinuance of goodwill amortization. In addition, SFAS 142 requires
the Company to perform a transitional goodwill impairment test within six months from the date of adoption. In
accordance with the standard, the Company completed the transitional goodwill impairment test and determined
that a $57,000 goodwill impairment charge was required. Under SFAS 142, goodwill is to be reviewed at least
annually thereafter for impairment; the Company has elected to perform this review annually on June 30 of each
calendar year. Goodwill amortization expense for the years ended December 31, 2001 and 2000 was $1,138,000
and $1,124,000, respectively. Net income for the years ended December 31, 2001 and 2000, assuming goodwill
was not amortized during this period would have been $1,835,000 and $2,789,000, respectively. Fully diluted
earnings per share for the years ended December 31, 2001 and 2000, assuming goodwill was not amortized
during this period would have been $0.10 and $0.15, respectively.

On December 17, 2001, the Company executed a new Business Loan and Security Agreement (the Agreement)
with Citizens Bank of Pennsylvania, PNC Bank N.A., Branch Banking and Trust Company of Virginia, and
Chevy Chase Bank, F.S.B. to refinance and replace the Company’s prior agreement. The Agreement provides for
maximum borrowings of $71.4 million and consists of a $65.0 million revolving credit facility and a $6.4 million
term loan. Under the term loan portion of the Agreement, the principal balance is payable in consecutive
quarterly installments of $492,308 on the last business day of each quarter commencing with the last business
day of December 2001. The balance of the term loan was repaid in February 2002. The maturity date of the
Agreement is December 31, 2004. In July 2002, the Agreement was amended in order to modify the pricing grid
and certain financial and negative covenants.

The maximum available borrowing under the revolving credit facility at December 31, 2002 was $65.0 million.
As of December 31, 2002, the Company was contingently liable under letters of credit totaling $8,824,000, which
reduce the availability to borrow under the revolving portion of the Agreement. The Company had $23.0 million
in borrowings at December 31, 2001, which were repaid immediately after the end of the period. Borrowings
under the Agreement are collateralized by the Company’s eligible contract receivables, inventory, all of the
Company’s stock in certain of its subsidiaries and certain property and equipment and bear interest at the agreed-
upon London Interbank Offered Rate (LIBOR) plus 1.00% for the $25.0 million outstanding. Additional
borrowings would bear interest at LIBOR, or the lender’s prime rate, plus market-rate spreads that are
determined based on a company leverage ratio calculation. At December 31, 2002, the agreed-upon LIBOR rate
was 1.42% for the $25.0 million and the bank’s prime rate was 4.25%. The aggregate annual weighted average
interest rates were 9.15%, 8.41% and 8.75% for 2002, 2001 and 2000, respectively.

Under the Agreement, the Company is required to maintain specified financial covenants relating to fixed charge
coverage, interest coverage, debt coverage, and to maintain a certain level of consolidated net worth. The
Agreement also places limitations on additional borrowings, mergers, and related party transactions, issuances of

47

capital stock and payment of dividends, and limitations with respect to capital expenditures. The weighted
average borrowings under the revolving portion of the Agreement and a prior agreement during the years ended
December 31, 2002, 2001 and 2000, were $27,172,000, $37,719,000, and $43,876,000, respectively. In
conjunction with the execution of the Agreement, the Company recorded $357,000 in loan origination costs,
included in other assets, which are being amortized ratably over the term of the Agreement.

On October 27, 2000, the Company executed the Second Amendment to the Amended and Restated Business
Loan and Security Agreement (the Prior Agreement) with Mellon Bank N.A., First Union Commercial
Corporation and PNC Bank N.A., which provided for maximum borrowings of $76.0 million. The Prior
Agreement consisted of a $60.0 million revolving credit facility and a $16.0 million term loan. Under the
revolving portion of the Prior Agreement, the Company could borrow the lesser of defined percentages of
receivables or $60.0 million. Under the term loan portion of the Prior Agreement, the principal balance was
payable in consecutive quarterly installments of $800,000 on the last business day of each quarter commencing
with the last business day of December 1998. A final payment of $6.4 million was due upon expiration of the
Prior Agreement on December 31, 2001.

Borrowings under the Prior Agreement were collateralized by the Company’s eligible contract receivables,
inventory, and certain property and equipment and accrued interest at the agreed-upon LIBOR plus market-rate
spreads that varied according to the calculation of a certain Company leverage ratio. Under the Prior Agreement,
the Company was required to maintain specified financial covenants relating to fixed charge coverage, interest
coverage, debt coverage, and minimum consolidated net worth. The Prior Agreement also placed limitations on
issuances of capital stock and payment of
additional borrowing, mergers, and related party transactions,
dividends, and limitations with respect to capital expenditures.

On January 15, 1998, the Company redeemed all 75,000 shares of its then outstanding Preferred Stock for a total
of $8,029,000, or $107.05 per share. In order to provide the funding necessary to redeem the Preferred Stock, the
Company executed a seven-year Subordinated Credit Agreement with First Source Financial LLP for $8,000,000
on January 9, 1998. The remaining $29,000 of funding was provided by the Company’s revolving credit facility.
The principal balance was payable in eight consecutive quarterly installments of $888,889 on the first business
day of each quarter commencing with the first business day of January 2003. A ninth and final payment of
$888,888 was due on the last business day of December 2004. Interest under the Subordinated Credit Agreement
accrued at a fixed rate of 12.0% per annum and was payable quarterly in arrears. The balance and accrued
interest associated with this facility was repaid in February 2002.

Debt outstanding at December 31, 2002, is scheduled to mature by the following calendar year ends: $1,000,000
in 2003 and $25,000,000 in 2004.

The total interest paid was $2,671,000, $5,005,000 and $6,073,000, for the years ended December 31, 2002, 2001
and 2000, respectively.

The Company uses interest rate swap agreements to manage exposure to fluctuations in interest rates. At
December 31, 2002, the Company had an unleveraged swap agreement with a member of the Company’s
banking group with a notional principal amount of $25,000,000. This agreement was placed on December 17,
2001 and has a four-year term. The agreement has a fixed LIBOR rate of 6.83% and is settled in cash on a
monthly basis.

Effective January 1, 2001, the Company adopted SFAS No. 133, Accounting for Derivative Instruments and
Hedging Activities, which, as amended by SFAS No. 138, establishes accounting and reporting standards for
derivative instruments, including some derivative instruments embedded in other contracts, and for hedging
activities. Upon adoption of SFAS No. 133, the Company recorded a $704,000 ($422,000 net of tax) transition
adjustment in Other comprehensive loss as the cumulative effect of a change in accounting principle. The
Company will reclassify this amount into interest expense over the remaining life of the interest rate swap. The

48

amount of the transition adjustment that was reclassified into earnings over the 12 months following the initial
adoption of SFAS No. 133 was $180,000.

The Company hedges the cash flows of some of its long-term debt using an interest rate swap. The Company
enters into these derivative contracts to manage its exposure to interest rate movements by achieving a desired
proportion of fixed-rate versus variable-rate debt. In an interest rate swap, the Company agrees to exchange the
difference between a variable interest rate and either a fixed or another variable interest rate, multiplied by a
notional principal amount.

As of December 31, 2002, the Company has recognized the cash flow hedge at its fair value of $3,326,000 in
accounts payable and accrued expenses on the consolidated balance sheet. The interest rate swap qualifies for
cash flow hedge accounting; therefore, an unrealized loss of $2,622,000 ($1,574,000 net of tax), representing the
effective portion of the change in its fair value, is reported in other comprehensive loss and will be reclassified
into interest expense. The ineffective portion of the change in fair value of the swap qualifying for cash flow
hedge accounting is recognized in the consolidated statements of income in the period of the change. For the year
ended December 31, 2002, the swap did not have any ineffectiveness for the cash flow hedge.

Management believes that the fair value of debt is not significantly different from what is recorded by the
Company, based on comparable market rates on similar issues.

9. Income Taxes

For periods prior to the closing of the Company’s Initial Public Offering on February 12, 2002, the Company
accounted for earnings on a cash basis for federal income tax purposes. Effective as of the closing of the offering,
the Company changed to the accrual method of accounting, resulting in previously deferred income being
recognized for tax purposes. As such, taxes will be due with respect to the four taxable years beginning with the
taxable year of the offering. Because the Company previously recognized the deferred income for accounting
purposes and accrued for the taxes, the change in tax status and the tax payments will not affect the Company’s
earnings.

10. Stockholders’ Equity and Stock Options

Initial Public Offering—The Company closed its Initial Public Offering on February 12, 2002. Net proceeds to
the Company were approximately $110.2 million, after deducting the estimated expenses related to the offering
and the portion of the underwriting discount payable by the Company. Proceeds from the offering were used to

50

repay subordinated debt of $8.0 million, the balance of the term loan of $5.9 million, $17.7 million of the
revolving credit facility, plus accrued interest, and $69.1 million was used to fund the Company’s acquisition of
Aegis Research Corporation on August 5, 2002. The balance of the net proceeds of the offering, in conjunction
with additional borrowings under the Company’s revolver, were used to fund the Company’s $35.3 million
acquisition of CTX Corporation on December 11, 2002.

Reincorporation, Recapitalization and Stock Split—The Company is incorporated in Delaware and is the
successor by merger to ManTech International Corporation, a New Jersey corporation. As a result of the merger,
in January 2002 the Company reincorporated from New Jersey to Delaware and recapitalized its common stock.
On the effective date of the merger, each outstanding share of the New Jersey corporation’s common stock was
exchanged for one share of the Company’s Class A common stock or for one share of the Company’s Class B
common stock. Immediately after the merger, the Company effected a 16.3062-for-one stock split of the
Company’s Class A common stock and Class B common stock. In connection with the reincorporation and
recapitalization, all of the Company’s outstanding Treasury Stock was retired.

Follow-on Public Offering—The Company closed its Follow-on Public Offering on December 20, 2002. Net
proceeds to the Company were approximately $90.9 million, after deducting the estimated expenses related to the
offering and the portion of the underwriting discount payable by the Company. Proceeds from the offering were
used to repay indebtedness incurred in connection with the acquisition of CTX Corporation. The balance of the
net proceeds of the offering, in conjunction with cash on hand, was used in 2003 to fund the Company’s
acquisition of Integrated Data Systems on February 28, 2003 and MSM Security Services, Inc. on March 1, 2003
for $62.7 million and $4.6 million, respectively (see note 17).

Common Stock—The Company has 150,000,000 shares of authorized Class A common stock, par value $0.01
per share. The Company has 50,000,000 shares of authorized Class B common stock, par value $0.01 per share.
On December 31, 2002, there were 16,267,213 shares of Class A common stock outstanding and 15,631,004
shares of Class B common stock outstanding.

Holders of Class A common stock are entitled to one vote for each share held of record, and holders of Class B
common stock are entitled to ten votes for each share held of record, except with respect to any “going private
transaction” (generally, a transaction in which Mr. Pedersen, his affiliates, his direct and indirect permitted
transferees or a group, generally including Mr. Pedersen, such affiliates and permitted transferees, seek to buy all
outstanding shares), as to which each share of Class A common stock and Class B common stock are entitled to
one vote per share. The Class A common stock and the Class B common stock vote together as a single class on
all matters submitted to a vote of stockholders, including the election of directors, except as required by law.
Holders of common stock do not have cumulative voting rights in the election of directors.

Stockholders are entitled to receive, when and if declared by the board of directors from time to time, such
dividends and other distributions in cash, stock or property from the Company’s assets or funds legally available
for such purposes subject to any dividend preferences that may be attributable to preferred stock that may be
authorized. Each share of Class A common stock and Class B common stock is equal in respect of dividends and
other distributions in cash, stock or property, except that in the case of stock dividends, only shares of Class A
common stock will be distributed with respect to the Class A common stock and only shares of Class B common
stock will be distributed with respect to Class B common stock. In no event will either Class A common stock or
Class B common stock be split, divided or combined unless the other class is proportionately split, divided or
combined.

The shares of Class A common stock are not convertible into any other series or class of securities. Each share of
Class B common stock, however, is freely convertible into one share of Class A common stock at the option of
the Class B stockholder. Upon the death or permanent mental incapacity of the Mr. Pedersen, all outstanding
shares of Class B common stock automatically convert to Class A common stock.

51

The predecessor corporation had three classes of common stock outstanding prior to the effective date of the
merger: Class A common stock, Class B common stock and Class C common stock, of which the Class B
common stock was redeemable and, therefore, not reflected as equity for accounting purposes. The Class A
common stock was voting, no par value. The Class B common stock was nonvoting, no par value, and was
mandatorily redeemable by the stockholder at any time or by the Company in the event of the involuntary or
voluntary termination of the stockholder’s position within the Company at a per share price to be determined by
an independent valuation company. On January 6, 2000, the Company redeemed 6,582 shares of Class B
common stock from an employee for $566,082. On February 29, 2000, the Company redeemed 1,000 shares of
Class B common stock from an outside Director for $86,060. On December 18, 2000, the Company redeemed an
additional 1,000 shares of Class B common stock from an outside Director for $123,240. All of these shares were
placed in Treasury at their redemption value. The Class C common stock was nonvoting, no par value.

Preferred Stock—The Company is authorized to issue an aggregate of 20,000,000 shares of preferred stock,
$0.01 par value per share, the terms and conditions of which are determined by the Company’s board of directors
upon issuance. The rights, preferences and privileges of holders of the Company’s common stock are subject to,
and may be adversely affected by, the rights of holders of any shares of preferred stock that the Company may
designate and issue in the future. At December 31, 2002, no shares of preferred stock are outstanding and the
board of directors currently has no plans to issue a series of preferred stock.

Shares Held in Grantor Trust—At December 31, 2002 and 2001, there were an additional 609,296 shares of
Class B common stock, with a cost value of $640,000, reflected in equity in accordance with EITF 97-14,
Accounting for Deferred Compensation Arrangements where Amounts Earned are Held in a Rabbi Trust and
Invested. These shares are held in a Rabbi Trust to satisfy a defined contribution pension obligation, to be paid in
stock for the benefit of Mr. Pedersen.

Stock Options—In January 2002, the board of directors adopted and the stockholders approved the Company’s
Management Incentive Plan (the Plan), designed to enable the Company to attract, retain and motivate key
employees. In connection with the creation of the Plan, all options outstanding under the ManTech International
Corporation 1995 Long-Term Incentive Plan were assumed. Awards granted under the Plan may be settled in
cash, shares of Class A common stock or a combination thereof, or by stock units which provide for settlement in
cash or deferred issuance of shares of Class A common stock. The aggregate number of shares of the Company’s
Class A common stock that is available for issuance under the Plan is 2,840,379 plus, in 2003 and each year
thereafter, a number of additional shares equal to one and one-half percent of the number of shares of Class A
common stock outstanding on December 31st of that year. The Management Incentive Plan expires in December
2012.

The plan is administered by the compensation committee of the Company’s board of directors, although the
board of directors may exercise any authority of the committee under the Plan and the compensation committee
may delegate its authority under the Plan. Subject to the express provisions of the Plan, the committee has broad
authority to administer and interpret the Plan, including the discretion to determine the exercise price, vesting
schedule and the number of shares to be issued.

The Company has adopted the disclosure-only provisions of SFAS No. 123, Accounting for Stock-Based
Compensation, which establishes financial accounting and reporting standards for stock-based compensation
plans and for transactions in which an entity issues its equity instruments to acquire goods and services from
nonemployees. The Plan provides that shares granted come from the Company’s authorized but unissued Class A
Common Stock. The exercise price of the options granted pursuant to the Plan was not less than 100% of the fair
market value of the shares on the date of grant. No compensation cost has been recognized for issuances under
the Plan. These options vest quarterly over a three-year period from the date of grant. In May 2002, options to
purchase 159,621 shares were exercised.

There were no stock options exercisable at December 31, 2002. Information with respect to stock option activity

The Company has 3-year options. For disclosure purposes, the fair value of each option is estimated on the date
of grant using the Black-Scholes (Minimum Value) option-pricing model. The following weighted-average
assumptions were used for option grants during the years ended December 31, 2002, 2001 and 2000,
respectively: dividend yield of 0 percent (as the Company did not pay dividends during the periods presented);
expected volatility of 32.1%, 0.0% and 0.0; expected average lives of 3 years, 1 year, and 2 years (based on the
Company’s experience); and, risk-free interest rates of 3.10%, 3.50%, and 6.25%. The weighted-average fair
value of the stock options granted during the year ended December 31, 2002 was $16.97. There were no stock
options granted during the years ended December 31, 2001 and 2000.

11. Retirement Plans

The Company maintains nonqualified supplemental defined benefit pension plans for certain retired employees
of an acquired company. The weighted average assumptions used in accounting for the Company’s pension plans
in 2002, 2001 and 2000 were as follows:

Discount rate . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The discount rate is the estimated rate at which the obligation for pension benefits could effectively be settled.
The expected return on plan assets reflects the average rate of earnings that the Company estimates will be
generated on the assets of the plans. The plans were partially funded beginning in 1999. The rate of
compensation increase reflects the Company’s best estimate of the future compensation levels of the individual
employees covered by the plans and is not applicable, as all covered employees had retired prior to 1998.

The Company maintains two qualified defined contribution plans, which cover substantially all employees,
which comply with Section 401 of the Internal Revenue Code. Under these plans, the Company’s stipulated
Basic Matching Contribution matches a portion of the participants’ contribution based upon a defined schedule.
Contributions are invested by an independent investment company in one or more of several investment
alternatives. The choice of investment alternatives is at the election of each participating employee. The
Company’s contributions to the plans were approximately $2,954,000, $2,554,000 and $2,420,000 for the years
ended December 31, 2002, 2001 and 2000, respectively.

The Company maintains non-qualified defined contribution supplemental retirement plans for certain key
employees. Under these plans the Company accrues a stated annual amount and may also include interest at the
greater of 10% or the Company’s annual rate of return on investments. The Company incurred expenses
associated with these plans and contributed $75,000 for each of the years ended December 31, 2002, 2001 and
2000.

The Company also maintains a non-qualified deferred compensation plan for certain key employees. Under this
plan, eligible employees may defer up to 18% of qualified annual compensation. Employee contributions to this
plan were approximately $1,788,000, $1,895,000 and $1,875,000 for the years ended December 31, 2002, 2001
and 2000, respectively.

54

On December 18, 1998, the board of directors approved the establishment of a qualified Employee Stock
Ownership Plan (ESOP), effective January 1, 1999, for the benefit of substantially all of the Company’s U.S.
domestic-based employees. The ESOP is non-leveraged and will be funded entirely through Company
contributions based on a percentage of eligible employee compensation, as defined in the plan. Participants must
be employees of the Company or eligible Company subsidiaries and must meet minimum service requirements to
be eligible for annual contributions. The ESOP specifies a five-year vesting schedule over which participants
become vested in the Class A common stock allocated to their participant account. The amount of the Company’s
annual contribution to the ESOP is at the discretion of the Company’s board of directors.

For the years ended December 31, 2001 and 2000, the Company contributed and allocated to participants’
accounts $1,376,000 and $1,419,000, respectively, worth of Class A common stock and cash. The board of
directors has authorized an additional ESOP contribution for the year ended December 31, 2002. As of
December 31, 2002, the Company has contributed 51,151 shares to the ESOP as partial satisfaction of this
obligation; however, these shares have not yet been allocated to participants’ accounts. It is anticipated that the
remaining shares attributable to the year ended December 31, 2002 commitment will be issued to the ESOP
during the first quarter of 2003. At December 31, 2002, an obligation to fund $394,000 was accrued.

As required under Statement of Position No. 93-6, Employers’ Accounting for Employee Stock Ownership Plans,
compensation expense is recorded for shares committed to be released to employees based on the fair market
value of those shares in the period in which they are committed to be released. The difference between cost and
fair market value of the released shares, which were held in Treasury, of $1,142,000 for the year ended
December 31, 2001, is recorded in additional paid in capital. For the year ended December 31, 2002, new shares
were issued to satisfy this obligation.

12. Investments

GSE Systems, Inc.—The Company and its designees hold stock in GSE Systems, Inc. (GSE), which was created
by the merger of one of the Company’s majority-owned subsidiaries and two other entities in April 1994. In
January 2000, the Company purchased 116,959 additional shares of common stock in GSE, increasing the
Company’s ownership to 17.61%. The Company’s ownership percentage of GSE was 15.59% at December 31,
2002. The Company’s and its designee’s ownership percentage of GSE was 17.97% at December 31, 2002. The
Company also holds $3.8 million of GSE convertible preferred stock and a $650,000 demand note receivable
from GSE as of December 31, 2002. This note accrues interest at the prime rate plus 1.00% and interest is
payable monthly.

During the year ended December 31, 2001, the Company determined that it had obtained significant influence
with respect to GSE. As a result, the Company began accounting for its investment in GSE using the equity
method and recorded $206,000 and ($85,000) in equity earnings (losses) for the years ended December 31, 2002
and 2001, respectively. Additionally, the Company restated prior year amounts and recorded ($1,555,000) in
equity losses for the year ended December 31, 2000. The after-tax impact to net income as a result of this
restatement was ($934,000) for the year ended December 31, 2000. The related impact to basic and diluted
earnings per share was ($0.82) for the year ended December 31, 2000.

Vosper-ManTech Limited—On September 7, 1995, MASI U.K. Limited, a majority-owned subsidiary of the
Company, and Vosper Thornycroft Limited entered into a Joint Venture agreement to form Vosper-ManTech
Limited (the Joint Venture). MASI U.K. Limited holds a 40% ownership in the Joint Venture and Vosper
Thornycroft Limited owns the remaining 60%. In 2000, the Joint Venture began work on a ten-year follow-on
contract providing outsourcing of the Government Communications Headquarters (GCHQ) for the United
Kingdom’s logistics and engineering services.

The Company’s interest in the Joint Venture is accounted for using the equity method. The Company recorded
$99,000, $504,000 and $393,000 in equity earnings for the years ended December 31, 2002, 2001 and 2000,
respectively.

13. Commitments and Contingencies

Payments to the Company on cost-reimbursable contracts with the U.S. Government are provisional payments
subject to adjustment upon audit by the DCAA. Audits through 2000 have been completed and resulted in no
material adjustments. The audits for 2001 and 2002 are not expected to have a material effect on the results of
future operations.

In February 2000, a judgment was entered against the Company in favor of Boston Properties, a real estate
management firm, in the amount of $1,175,000 for unpaid rent under a lease held by Boston Properties with
Global-InSync, Inc. (Global). Global is the successor to a business sold by the Company in 1996. The Company
provided a financial guarantee to Boston Properties on the lease to facilitate the timely closing of this business
sale. Boston Properties and Global extended the original lease without notice to the Company. The legal action
sought to recover unpaid rent beyond the term of the original lease. After losing the appeal, the Company paid
this judgment and other related expenses in August 2000.

On October 9, 2002, the Company received a document subpoena issued by the Department of Defense Office of
Inspector General. The Company is cooperating with the government. Based on the facts known to the Company,
the Company does not expect the consequences of the government’s investigation to have a material adverse
effect on its business, prospects, financial condition, or operating results. However, this investigation is at a
preliminary stage and it is not possible to tell how it may develop in the future.

In the normal course of business, the Company is involved in certain governmental and legal proceedings, claims
and disputes, and has litigation pending under several suits. Management believes that the ultimate resolution of
these matters will not have a material effect on the Company’s financial position or results of operations.

The Company leases office space and equipment under long-term operating leases. A number of the leases
contain renewal options and escalation clauses. At December 31, 2002, aggregate future minimum rental
commitments under these leases are as follows (in thousands):

Advanced Development Group, Inc.—On January 5, 1999, the Company acquired 100 percent of the outstanding
common shares of Advanced Development Group, Inc. (ADG) for a purchase price of $3.0 million and a note for
$2.0 million payable over two years (interest accrued at the prime rate). This acquisition also provided for
additional cash payments, not to exceed $5,000,000, to be made over the three years following the closing, based
on the attainment of certain earnings levels. In May 2000, the Company paid $495,000 against this obligation. At
December 31, 2002, the Company has accrued a liability in the amount of $230,000 to satisfy the remaining earn-
out obligation. ADG specializes in the development of interactive multimedia and distance learning training
products. It is the leading Interactive Multimedia Instruction (IMI) developer for the U.S. Army. In addition,
ADG has developed a proprietary IMI Course Builder Program© to enable the development of high-quality, low-
cost training products that incorporate sophisticated animation, graphics and video.

15. Discontinued Operations

On September 26, 2001, the Company executed a formal plan to exit certain commercial and foreign lines of
business that no longer contribute to the core competencies. The businesses include the Australia-based software
solutions consulting business, the United Kingdom-based bank remittance processing business, the China-based
consulting business, the U.S.-based environmental consulting and remediation business and the U.S.-based
application-hosting business. Although some of these ventures showed promise and growth, these businesses

58

were oriented towards commercial customers and did not contribute to the core competencies on which the
Company is currently focused. During the year ended December 31, 2002, the Company completed the sale of all
of these businesses.

Based on the projected future costs of disposal, an estimate has been provided for the likely net gains and losses
to income expected from these businesses through the estimated dates of disposal. As a result, in accordance with
APB Opinion No. 30, Reporting the Results of Operations—Reporting the Effects of Disposal of a Segment of a
Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions, results of operations
have been classified as discontinued and prior periods have been restated. The Company has segregated the net
assets and liabilities held for sale, recorded all current and expected future losses and deferred all gains expected
to be realized upon disposal of the respective entities. The amounts the Company will ultimately realize could
differ in the near term from the amounts estimated in arriving at the loss on disposal of the discontinued
operations.

Revenues and losses from discontinued operations are as follows (in thousands):

business on June 30, 2000 and recorded a loss on the disposal of $719,000, net of tax. The revenues and

statement disclosure during and through the date of the financial statements included in this Report.

61

PART III

The Information required by Items 10, 11, 12, and 13 of Part III of this Annual Report on Form 10-K has been
omitted in reliance on General Instruction G(3) and is incorporated herein by reference to the Company’s proxy
statement to be filed with the SEC pursuant to Regulation 14A promulgated under the Securities Exchange Act of
1934, as amended.

ITEM 14. CONTROLS AND PROCEDURES

“Disclosure controls and procedures” are the controls and other procedures of an issuer that are designed to
ensure that information required to be disclosed by the issuer in the reports filed or submitted by it under the
Securities Exchange Act of 1934, as amended (the “Exchange Act”) is recorded, processed, summarized and
reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. These
controls and procedures are designed to ensure that information required to be disclosed by an issuer in its
Exchange Act reports is accumulated and communicated to the issuer’s management, including its principal
executive and financial officers, as appropriate, to allow timely decisions regarding required disclosure.

Within the 90 days prior to the date of this report, under the supervision and with the participation of the
Company’s Chief Executive Officer and Chief Financial Officer, the Company carried out an evaluation of the
effectiveness of the design and operation of the Company’s disclosure controls and procedures pursuant to the
Exchange Act Rule 13a-14. Based upon the evaluation, the Chief Executive Officer and Chief Financial Officer
concluded that the Company’s disclosure controls and procedures are effective in timely alerting them to material
information relating to the Company (including its consolidated subsidiaries) required to be included in the
Company’s periodic SEC filings.

Since the evaluation, there were no significant changes in the Company’s internal controls or in other factors that
could significantly affect the Company’s disclosure controls and procedures, and there were no corrective actions
with regard to significant deficiencies or material weaknesses required.

INDEPENDENT AUDITORS’ REPORT ON FINANCIAL STATEMENT SCHEDULE

To the Board of Directors and Stockholders of ManTech International Corporation
Fairfax, Virginia:

We have audited the consolidated financial statements of ManTech International Corporation and
subsidiaries (the Company) as of December 31, 2002 and 2001, and for each of the three years in the period
ended December 31, 2002 and have issued our report thereon dated February 21, 2003. Our audit also included
the financial statement schedule for each of the three years in the period ended December 31, 2002 listed in Item
15(a)(2) of this Form 10-K. This financial statement schedule is the responsibility of the Company’s
management. Our responsibility is to express an opinion based on our audit. In our opinion, such financial
statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole,
presents fairly in all material respects the information set forth therein.
