ManTech International Corporation
2009
Annual Report
www.mantech.com
To our shareholders
We are delighted to report that 2009 was another
extremely successful year for ManTech. We passed
$2 billion in annual revenues, delivered excellent
growth in earnings and profi tability, strengthened
our balance sheet, and laid the foundation to
build a larger, stronger and more integrated
ManTech. That foundation begins with the skills
and dedication of our 8,900 employees working on
missions vital to the national interest and security.
Well positioned for growth
As we look ahead, our nation faces many challenges,
and ManTech stands ready to help. The recent
Quadrennial Defense Review laid out a national security
strategy, and President Obama has demonstrated his
commitment to that strategy through his government
fi scal year 2011 budget submission. These actions
validate our business strategy to focus on the high-
end defense and intelligence markets and make
us extremely well-positioned for growth. We have
established expertise and deep skills in growth areas of
the market: cyber security; intelligence, surveillance and
reconnaissance (ISR); logistics and sustainment services
for the warfi ghter; counter-terrorism and protection
of the homeland; and sophisticated support to the
Intelligence Community. Unlike our larger competitors,
we can serve our customers with advisory services
free of organizational confl icts of interest (OCI) from
performing production work, and we are aggressively
pursuing new business opportunities in this area.
Solid growth and one of the best balance sheets in
our industry
Our 2009 revenue was $2.02 billion, an 8 percent
increase compared to 2008. At ManTech, we are proud
to serve our customers wherever they need us, and our
growth was driven by our in-theater logistics support as
well as our cyber security business. Our net income for
2009 was $112 million, up 24 percent compared to $90
million in 2008. Diluted earnings per share were $3.11
in 2009, versus $2.55 for 2008, a 22 percent increase.
We improved an already stellar balance sheet and
cash fl ow levels. Cash fl ow from operating activities
for 2009 was $132 million, or 1.2 times net income.
This excellent conversion ratio was the result of our
effi cient collections process and discipline around cash

management. We closed out the year with $86 million
in cash and equivalents and no debt, which puts us in
great position to aggressively pursue strategic, accretive
acquisitions.
Since our last report, we acquired two companies that
expand our reach with new and existing customers. In
March 2009 we purchased DDK Technology Group, Inc.,
a provider of cyber security services to the Department
of Defense, with a particular focus on the Naval Criminal
Investigative Service. In January 2010, we acquired
Sensor Technologies Inc. (STI) for $242 million in cash.
STI was a leading provider of mission-critical systems
engineering and ISR solutions to the U.S. Army. As part
of ManTech, STI will continue its strong growth path and
provide a key prime contract position that enables us
to provide even more mission-critical ISR support to our
Army customer at a more competitive price.
A renewed focus on top-line growth, talent
management and program execution
Led by experienced additions to our management
team, we increased our focus on three key areas:
top-line growth, talent management and program
execution. This renewed focus is an important step as
ManTech International Corporation
Annual Report 2009
we prepare for higher levels of growth. To support our ascent we realigned our operating units around three groups
under the leadership of proven industry executives – Technical Services led by Lou Addeo, Systems Engineering
and Advanced Technology led by Terry Ryan, and Mission, Cyber and Technology Solutions led by Bill Varner. We
augmented that group with industry-experienced senior corporate leaders in business development, talent
management and strategy and communications.
Our contract awards seed our top-line growth, and in 2009 they totaled $1.95 billion. More than 70 percent of that
total represented new business awards, which positions us to achieve our guidance of at least 12 percent organic
growth in 2010. Importantly, our awards were spread across the enterprise and set the stage for balanced growth.
We have built the foundation for that growth by increasing our headcount from about 8,000 at the end of the third
quarter in 2009 to almost 9,000 today.
Our Technical Services Group received a $355 million award from the U.S. Army to support mine-resistant ambush-
protected vehicles in Southwest Asia and a $286 million contract from the Army Electronic Proving Ground in Fort
Huachuca, AZ, to provide engineering and technical support for Command, Control, Communications, Computers
and Intelligence (C4I) testing.
The Systems Engineering and Advanced Technology Group won a $99 million contract from the Department of
Homeland Security (DHS) Secure Border Initiative program offi ce for systems engineering and technical support.
This momentum has continued into the start of fi scal year 2010 with two large, classifi ed, systems engineering
contracts.
In our Mission, Cyber and Technology Solutions Group we received a $135 million award from DHS to support
critical infrastructure protection and a $76 million contract to support the information technology infrastructure
for the National Media Exploitation Center, which provides strategic document and media exploitation support to
the Intelligence Community, law enforcement and the Department of Defense. We also received signifi cant new
funding on our largest cyber security contract for a classifi ed customer.
We mourned the loss of one of our employees
ManTech employee Kenneth Rose was killed in Afghanistan while on a mission to repair a damaged vehicle. We
will be forever grateful for his sacrifi ce. Kenneth exemplifi ed the courage and dedication of the more than 1,400
ManTech employees working outside the U.S., many of whom put their lives at risk every day to protect our nation.
We think of them always and hope for their continued safety.
A legacy of success and a future fi lled with promise
For 42 years we have successfully provided advanced technology for our country’s mission-critical national security
programs – this has been our hallmark and will continue to be our focus. Along with our mission success, we are
a leader in our peer group in fi nancial performance and growth. Since going public in 2002 our revenues and
earnings per share have grown on a compound annual basis of 22 and 20 percent, respectively. Our balance sheet
and credit rating are as strong as ever allowing us to invest in organic growth and strategic acquisitions. These
elements, combined with our fortifi ed management team, give us high confi dence in our ability to grow to a $3
billion to $5 billion enterprise and continue to provide industry-leading value to our shareholders.

ManTech received a $76 million competitive award for the IT operations and mission support program from the
National Media Exploitation Center (NMEC) in the third quarter of 2009. ManTech provides NMEC with data center
operations, network operations, software engineering, systems engineering, information assurance, requirements
management, confi guration management, and project/program management support. NMEC is a Director of National
Intelligence program with the Defense Intelligence Agency as the executive agent. It requires petabytes of storage and
the development of cutting-edge document and media exploitation tools.
Cyber Security and Intelligence Support
The current and projected federal budgets provide funding for the Comprehensive National Cyber Initiative (CNCI),
intelligence, surveillance and reconnaissance (ISR) and other intelligence customers. We have received additional
funding on key cyber contracts, where we provide reverse engineering, vulnerability assessments, computer
network operations, computer network forensics and training support to help our government “operate eff ectively
in cyberspace,” one of the critical elements specifi ed in the Quadrennial Defense Review. We integrate and operate
sensors to collect intelligence to support military operations and counter insurgency and terrorist activity, and we will
leverage the Sensor Technologies Inc. acquisition to expand our presence in the ISR market.

Forward-Looking Statement
This summary annual report contains forward-looking statements that involve substantial risks and uncertainties, many of which
are outside of our control. We believe that these statements are within the defi nition of the Private Securities Litigation Reform Act
of 1995. You can identify these statements by the use of words such as “may,” “will,” “expect,” “intend,” “anticipate,” “believe,” “plan,”
“seek,” “estimate,” “continue” and other similar words. You should read our forward-looking statements carefully because they discuss
our future expectations, make projections of our future results of operations or fi nancial condition, or state other “forward-looking”
information.
Although forward-looking statements in this summary annual report refl ect the good faith judgment of management, such statements
can only be based on facts and factors currently known by us. Consequently, forward-looking statements are inherently subject to
risks and uncertainties and actual results and outcomes may diff er materially from the results and outcomes discussed in or anticipated
by the forward-looking statements. We believe that it is important to communicate our future expectations to our investors. However,
there may be events in the future that we are not able to predict accurately or control. Factors that could cause actual results to diff er
materially from the results we anticipate include, without limitation: adverse changes in U.S. government spending priorities; failure
to retain existing U.S. government contracts, win new contracts, or win recompetes; adverse results of U.S. government audits of our
government contracts; risks associated with complex U.S. government procurement laws and regulations; adverse eff ect of contract
consolidations; risk of contract performance or termination; failure to obtain option awards, task orders or funding under contracts;
adverse changes in our mix of contract types; failure to successfully integrate recently acquired companies or businesses into our
operations or to realize any accretive or synergistic eff ects from such acquisitions; failure to identify, execute or eff ectively integrate
future acquisitions; risks of fi nancing, such as increases in interest rates and restrictions imposed by our credit agreement; risks related
to an inability to obtain new or additional fi nancing; and competition. These and other risk factors are more fully discussed in Item 1A
“Risk Factors” as well as elsewhere in our Annual Report on Form 10-K, fi led with the SEC on February 26, 2010, and from time to time in
our other fi lings with the SEC, including our reports on Form 10-Q and Form 8-K.
We urge you not to place undue reliance on these forward-looking statements, which speak only as of the date of this summary annual
report. We undertake no obligation to update any forward-looking statements in order to refl ect any event or circumstance that may
arise after the date of this summary annual report. We also suggest that you carefully review and consider the various disclosures
made in our Annual Report on Form 10-K and other fi lings with the SEC that attempt to advise interested parties of the risks and
factors that may aff ect our business, fi nancial condition, results of operations and prospects.
