To Our Shareholders

In 2013, ManTech celebrated 45 years of helping our customers meet 
their most difficult challenges. We provide trusted solutions in cyber 
security,  information  technology,  healthcare,  systems  engineering, 
and  global  logistics  to  all  branches  of  the  Department  of  Defense 
(DoD), intelligence agencies, Department of Homeland Security (DHS), 
and many other U.S. government agencies. Our broad suite of contract 
vehicles,  proven  track  record  of  global  delivery,  and  deep  roster  of 
cleared  technology  experts  in  22  countries  enable  us  to  provide 
exceptional service to our customers around the world.

ManTech’s revenue and earnings declined in 
2013 because of the government’s accelerated 
withdrawal from Afghanistan. This uncertainty 
was made manifest when, for the first time in 
nearly 20 years, most government operations 
unexpectedly ceased because Congress could not 
pass a budget. Throughout the year, our customers 
delayed procurements and held off spending. These 
conditions led to an impairment of goodwill that 
we accumulated over the past decade growing the 
company. This accounting charge had no impact 
on cash, and we generated outstanding cash flows, 
ending the year with a record cash balance of $269 
million.

In January 2014, Congress put in place a 2-year 
framework for discretionary spending that eases 
harmful sequestration cuts. With full-year 2014 
appropriations enacted, our customers have the 
authority to prioritize their most important missions. 
The appropriations provide stability across our 
business base, as operations and maintenance 
accounts were generally protected, with areas such 
as cyber, intelligence, healthcare, and homeland 
security emerging as priorities. Our customers have 
begun actively carrying out plans for the future, 
accelerating procurements instead of delaying them.

Each of our two operating groups offers compelling 
capabilities pointed toward key growth markets. 
Just as important, each of them continues to deliver 
outstanding support to its customers. In 2013, 
we witnessed tremendous performance by our 
employees in service to some of the nation’s most 
important missions.

CYBER AND INTELLIGENCE LEADER

Our Mission, Cyber, & Intelligence Solutions (MCIS) 
Group, led by Bill Varner, provides full-spectrum 
solutions across the cyber domain and offers 
information technology, systems engineering 
and integration, data analytics, mission support, 
and integrated security solutions to intelligence 
customers. We are a leader in counterintelligence 
and insider-threat detection, which is increasingly 
critical to intelligence, government, and commercial 
customers. 

During 2013, our cyber and intelligence business 
showed vibrant, double-digit growth and generated 
strong new business awards. Key highlights for the 
year included establishing a significant presence in 
Denver, unseating long-time incumbents providing 
security operations center support and program 
security support to major intelligence customers, 
and gaining entry into the critical infrastructure 
market with initial contracts in the banking and 
transportation sectors. Major successes during the 
year include:

•  Our FBI Enterprise Security Operations Center 
(ESOC) customer was awarded the Frank. B. 
Rowlett Award by the National Security Agency 
in recognition of the ESOC’s outstanding 
organizational excellence in the field of 
information systems security for 2013. The 
Frank B. Rowlett Award recognizes individual 
and organizational one-time or long-term 
achievement in the improvement of national 
information systems security, information 
assurance readiness, or defensive information 
operations.

ManTech International Corporation2012 Annual Report•  Our skills in multiple digital forensic cases for both 
unclassified and classified investigations of Army 
network intrusions were leveraged during the 
multi-year investigation and prosecution of Private 
Bradley Manning. ManTech supplied an employee 
as forensic examiner to provide testimony on 
digital forensic findings at both the Article 32 
hearing in December 2011 and as a vetted expert 
witness during the court martial trial in June 
2012. Manning was ultimately charged with 22 
offenses related to the largest release of classified 
information in U.S. history. Manning was convicted 
of most charges, sentenced to 35 years in military 
prison, and dishonorably discharged from the 
Army.

MISSION-CRITICAL NATIONAL SECURITY 
PROVIDER

Our Mission Solutions & Services (MSS) Group, 
led by Dan Keefe, focuses on command, control, 
communications, computers, intelligence, 
surveillance, and reconnaissance (C4ISR); information 
technology; global logistics; systems engineering, 
test and evaluation; mission assurance; and training 
for defense and federal civil customers. This group 
has seen pressure from the withdrawal from 
Afghanistan, but it also has provided the most 
compelling support to critical missions.

ManTech has focused on national security, and we 
are proud to support warfighters around the world. 
Major successes during the year include:

•  Forward deployed in the inhospitable 

environment and climate of Afghanistan, our 
employees keep the lifesaving, survivable vehicles 
that perform the vital route-clearance mission 
operational and on the road. Operating from large 
fixed bases, small outposts, or embedded with 
Army or Marine units, we help keep American 
and coalition troops safe. With temperatures that 
soar above 120°F in the summer and drop to 
nearly 0°F in the winter, our team works 12-hour 
shifts, 7 days per week, to maintain or to repair 
battle-damaged route-clearance and special 
operations vehicles. Even as American forces begin 
to withdraw from Afghanistan and our workforce 
gets smaller, we exceed the challenging contract 
goals for operational availability and maintenance 
turnaround time. Every day, our employees 
demonstrate the ManTech ethos to go where our 
customers go.

•  The Base Expeditionary Target Surveillance 

System-Combined (BETSS-C) system comprises 
a combination of intelligence, surveillance, 
reconnaissance (ISR); battle command; and force 
protection systems and represents the very best 
in systems engineering and integration. The 
component BETSS-C systems are much more 
powerful to the warfighter because they are 
integrated, networked, scalable, and adjustable 
to changing environments in theater and shifting 
warfighter needs. ManTech stood up the BETSS-C 
repair facility during 2013 and decreased the 
Army’s dependency on manufacturers, with 
ManTech conducting the vast majority of repairs. 
ManTech performed at double the Army’s target 
throughput, generating significant savings and 
returning equipment to service in days instead of 
months.

Consistent with the increasing concentration of the 
group on the homeland security, healthcare, and 
federal civilian markets, we leveraged our Army ISR 
expertise for DHS:

•  Our onsite team leveraged ManTech’s engineering 
and test capabilities to enable Customs and Border 
Protection (CBP), a component agency of DHS, 
to deploy and operate three excess aerostats and 
repositionable towers in the Rio Grande Valley. The 
result was accelerated system availability of excess 
DoD equipment to CBP Border Patrol by more 
than 12 months. The timely delivery and operation 
of the aerostats enabled CBP to greatly increase 
the number of border-crossing apprehensions, 
turnbacks, and illegal drug seizures. ManTech also 
facilitated CBP analysis and selection of more than 
1,300 excess DoD technology items delivered to 
CBP operational units on the border, achieving a 
$24 million cost avoidance.

NEW YEAR BRINGS NEW GROWTH

We see 2014 as our transition year. We expect the 
improved funding picture to translate into a sharp 
increase in new awards, revenue, and earnings as we 
exit the year. 

We began 2014 with the acquisition of Allied 
Technology Group (ATG), which gives us a more 
robust platform within DHS. Together, we can 
leverage our capabilities through ATG’s prime 
position on two contracts that provide $33 billion 
in potential ceiling value for use by all of the DHS 

2

of high-yield debt. We will begin to see positive 
returns from investments in cyber products and 
commercial services. Along with our acquisition 
strategy, these activities will help reshape our 
business with greater exposure to healthcare, DHS, 
intelligence, and other customers or capabilities we 
identify as national and commercial priorities.

George J. Pedersen
Chairman of the Board and CEO

components. ManTech is well positioned to help 
DHS perform its growing cyber mission, secure the 
nation’s borders, and keep America safe. 

The improving funding picture gives us the clarity 
to move away from the conservative approach to 
acquisitions that we have taken over the last 2 years 
and aggressively use our balance sheet for growth. 
We have a strong balance sheet and expect to 
complete more acquisitions in 2014, especially in 
cyber, intelligence, healthcare, and enterprise IT. 

Our confidence in the future spending levels also 
enables us to invest in new areas of growth from an 
organic basis. In the coming year, we will invest in 
building a commercial services business focused on 
select software tools, targeting such areas as banking 
and energy. We will also invest in further internal 
research and development in some of our key cyber, 
mobility, and insider-threat capabilities. Over time, 
I expect ManTech to grow our returns as we enter 
high-growth, high-value markets. 

The outlook for revenue and earnings heading into 
2015 is very positive. As we move through the latter 
part of 2014, we will drive general and administrative 
savings through IT investments made this year. We 
will have much lower interest costs, given retirement

Solutions for Every Mission

ManTech International Corporation uses advanced technology to help government and 
business meet some of their greatest challenges and succeed in their most important 
endeavors.

We are experts in IT, and we apply our knowledge of different technologies to manage and protect information, 
support and maintain critical systems, and develop integrated systems to handle complex needs.

With over 45 years of experience in technology, we have earned our stripes in the very challenging world of 
national security. Throughout our history, starting with a single U.S. Navy contract, we have adapted skillfully to 
changing conditions.

Today, as a multi-billion-dollar public company, we apply our knowledge to national security, cyber, healthcare, 
law enforcement, business and citizen services, as well as to defense, diplomacy, homeland security, and 
intelligence.

ManTech’s Emerging Cyber Strength

In many ways, 2013 was the year of cyber 
for ManTech. This emerging discipline 
became a major point of emphasis 
for our business and allowed us to 
provide an added value offering to our 
partners in the last calendar year. There 
are few priorities more important for 
our federal government officials than 
keeping our nation and government 
information infrastructure safe from cyber 
attacks. There was none more related 
to ManTech’s cyber security offering 
than the announcement last year that 
DHS awarded ManTech a 5-year Blanket 
Purchase Agreement (BPA) to provide 
cyber security services and integration for 
continuous diagnostics and mitigation 
across a wide range of dot.gov networks. 
ManTech’s experts will work side by side 
with a variety of federal agencies to 
ensure that sensitive information remains 
secure and that personal information for 
millions of consumers remains protected.

ManTech Delivers Best-of-Breed Solutions 
to the Marketplace

ManTech offers an industry-leading suite of government and commercial solutions that have 
been mastered from significant experience addressing national security and technology 
challenges. We have continued to grow and evolve our customer offerings to ensure that we 
address emerging disciplines like healthcare, cyber security, and sustainability among other 
important business challenges. 

CYBER SECURITY  

ManTech approaches cyber security solutions from 
a full-spectrum security services standpoint that can 
adapt to changing needs in real time. We provide our 
customers with a comprehensive, cost-efficient, and 
effective cyber security solution that provides real 
security and peace of mind.  

HEALTHCARE

ManTech has been delivering integrated healthcare 
technology solutions since 2000, focusing on federal 
and military healthcare IT. 

IT

ManTech provides a full spectrum of information 
technology/information systems services and 
facilities in a process-driven environment. 

INTELLIGENCE LIFECYCLE

Our ManTech intelligence and counterintelligence 
(CI) solutions provide information that helps to 
protect critical infrastructure assets and national 
security resources with customizable programs.

SYSTEMS ENGINEERING

ManTech is a leader in the application of systems 
engineering across a wide array of large-scale system 
development and acquisition programs used by 
government and industry. 

TRAINING

ManTech’s training organizations remain consistently 
capable of meeting any training need our customers 
have encountered. We have developed training 
curriculum for more than 150 occupational 
specialties, delivering thousands of hours of 

instructional material for use in classrooms, on the 
job, via distributable DVD, or on enterprise learning 
management systems.

TEST AND EVALUATION 

The U.S. military relies on the accuracy and 
effectiveness of weapons and systems; that’s why 
ManTech’s test and evaluation (T&E) solutions are a 
critical step in the integration and use of systems of 
weapons. 

MISSION ASSURANCE

ManTech provides comprehensive mission assurance 
in the development, acquisition, manufacturing, 
testing, integration, and site support of mission-
critical systems to include space lift and satellite 
systems.

GLOBAL LOGISTICS

When designing, operating, and maintaining 
logistics systems is done right, the operational 
lifecycle of any weapons or equipment system is 
enhanced, and the turnaround to bring systems back 
online is diminished – and that’s the kind of global 
logistics solution we provide at ManTech.

Our People – The Pulse of ManTech

OUR MANTECH EXPERTS

The lifeline of ManTech is our diverse base of experienced employees – our truest differentiator. 
Approximately 8,000 talented employees around the world comprise ManTech. More than 70 percent hold 
government security clearances. ManTech’s work as a global company includes developing solutions
for sensitive clients and sectors, so our ability to draw from a wealth of cleared professionals willing to safeguard 
classified national security information is invaluable.

An employee referral program helps us identify and recruit top-quality candidates, and our competitive benefits 
and opportunities for professional development continue to attract stellar applicants.

OUR COMMITMENT TO VETERANS 

ManTech has been recognized as a leading employer of veterans. We are proud that 45 percent of our 
employees have a military background. We don’t just offer our veterans jobs, we offer them opportunities to 
grow, advance, and build a career at ManTech, with programs that are tailored to their experiences and needs. 
Recognition includes:

•  One of the 2013 Most Valuable Employers for Military® (CivilianJobs.com)
•  Member of the 100,000 Jobs Mission Coalition
•  One of the top 10 best employers for veterans (Military Times EDGE)
•  One of the top 100 Military Friendly Employers for 9 consecutive years (G.I. Jobs)
•  Member of the Military Spouse Employment Partnership 

Health Care Solutions Worthy of Our Wounded Warriors on the Mend

Through the years of our nation’s existence, military medical 
care has grown from a president’s firm reminder of a nation’s 
obligation to a complex system for active-duty military, retirees, 
their families, and veterans. Studies show that a significant 
percent of hospital expenses are invested in logistical necessities 
like storage, laundry, cleaning, etc., and that almost half the cost 
associated with supply chain processes could be eliminated by 
improving practices. ManTech’s experts are working to make this 
happen at one critical DoD program - the Joint Medical Logistics 
Functional Development Center (JMLFDC) with staff working 
from Ft. Detrick, Maryland, and Herndon, Virginia. ManTech 
manages hundreds of operations and ensures full operability 
through specialized support teams of systems, database, and 
network engineers who monitor each of the production sites 
and respond to product functionality issues reported by the end 
users. The JMLFDC was established to improve productivity and 
efficiency, provide better care and patient experience, decrease 
costs and manual tasks, and ensure patient safety. ManTech is 
doing its part to support that mission with technology solutions 
that support the sacrifice of our brave service members who rely 
on these facilities every day.

ManTech in the Community

Our commitment to service extends beyond our client-focused missions; we have a 
responsibility to our respective communities. We hope to make the world a better place by 
serving people in need at home and by supporting those who have served our country. We 
do this directly and by supporting the charitable initiatives of our employees whenever we 
can. We are in the business of service, and service isn’t just a job. It’s a way of life. Below are 
some of our key community partnerships.

CHARITYWORKS

THE IVYMOUNT SCHOOL

CharityWorks brings together business and 
community leaders to provide financial, voluntary, 
administrative, and technical support to worthy 
charities in the Washington, D.C., area. ManTech 
has supported CharityWorks since its founding, 
including its board of directors. ManTech supports 
CharityWorks’ fundraising activities each year 
with direct and in-kind contributions, and 
ManTech employees donate hundreds of hours to 
CharityWorks and its annual partners.   

FISHER HOUSE

Two of ManTech’s favorite causes coincided in 2013, 
when CharityWorks chose Fisher House as its partner 
organization. Each year, CharityWorks partners with 
one organization that supports military families 
and another that serves families and children in 
the Washington metropolitan area. Fisher House is 
a unique private–public partnership that provides 
a place to stay for family members of wounded 
military while their loved ones receive specialized 
in-patient treatment. ManTech has made significant 
contributions to Fisher House over the years. 

ManTech has had a very close relationship with The 
Ivymount School—a leader in special education, 
autism training, and developing special-needs 
children. For many years, we have provided financial 
support and a program that allows Ivymount 
students to gain valuable work experience at our 
corporate office twice a week during the school year. 
Ivymount’s mission is to enable students to develop 
their full potential, to support families in their efforts 
to make intelligent, thoughtful choices for their 
children, and to be a leader in the community and in 
the field of special education. 

CIA OFFICERS MEMORIAL FOUNDATION

ManTech has given significant support to the 
Central Intelligence Agency (CIA) Officers Memorial 
Foundation, which provides educational support to 
the children and spouses of CIA officers killed in the 
line of duty or as a result of accident, illness, or other 
causes. The foundation was created in December 
2001 to honor Johnny Micheal Spann, a CIA officer 
killed in the line of duty in Afghanistan responding 
to the terrorist attacks of September 11, 2001, and all 
those CIA officers who gave their lives in service to 
our nation since the founding of the CIA.

In this document, unless the context indicates otherwise, the terms “Company” and “ManTech” as well as the words “we”, 
“our”, “ours” and “us” refer to both ManTech International Corporation and its consolidated subsidiaries.  The term “registrant” 
refers only to ManTech International Corporation, a Delaware corporation.

Industry and market data used throughout this Annual Report on Form 10-K were obtained through surveys and studies 
conducted by third parties, industry and general publications and internal company research.  We have not independently verified 
any of the data from third-party sources nor have we ascertained any underlying economic assumptions relied upon therein.  While 
we are not aware of any misstatements regarding the industry data presented herein, estimates involve risks and uncertainties and 
are subject to change based on various factors, including those discussed in Item 1A “Risk Factors.”

Forward-Looking Statements

This Annual Report on Form 10-K 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 definition 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”, “estimate”, “continue”, or the negative of these terms or words of similar import.  You should read statements that 
contain these words carefully because they discuss our future expectations, make projections of our future results of operations 
or financial condition or state other “forward-looking” information.  

Although forward-looking statements in this Annual Report reflect our good faith judgment, 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 differ 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 
differ materially from the results we anticipate include, but are not limited to, those discussed in Item 1A “Risk Factors” below, 
as well as those discussed elsewhere in this Annual Report.  We urge you not to place undue reliance on these forward-looking 
statements, which speak only as of the date of this Annual Report.  We undertake no obligation to update any forward-looking 
statement herein after the date of this Annual Report, whether as a result of new information, subsequent events or circumstances, 
changes in expectations or otherwise.  We also suggest that you carefully review and consider the various disclosures made in this 
Annual Report that attempt to advise interested parties of the risks and factors that may affect our business, financial condition, 
results of operations and prospects.  

Item 1. 

Business

Business and Corporate Overview

ManTech is a leading provider of innovative technologies and solutions for mission-critical national security programs for 
the intelligence community; the departments of Defense, State, Homeland Security, Energy and Justice, including the Federal 
Bureau of Investigation (FBI); the healthcare and space communities; and other U.S. federal government customers.  

We support critical national security programs for approximately 50 federal agencies through over 1,000 current contracts.  
ManTech supports major national missions, such as cyber intelligence, terrorist threat detection, information security and border 
protection.    

ManTech was founded in 1968 as a New Jersey corporation and was reincorporated as a Delaware corporation in January 
2002, just prior to our Initial Public Offering (IPO) in February 2002.  We have grown substantially since going public, from 
revenues of $0.43 billion at the end of 2001 to revenues of $2.31 billion for the year ended December 31, 2013.  At December 31, 
2013,  we  had  approximately  7,800  employees.    For  additional  financial  information,  see  Item  8  “Financial  Statements  and 
Supplemental Data.”

Industry Background

Our primary customer is the U.S. federal government, the largest consumer of services and solutions in the United States.  In 

government fiscal year 2013, the U.S. federal government spent about $278 billion on contracted services.  

3

 
Our principal focus is on national security and homeland defense customers.   The Department of Defense (DoD) is the largest 
purchaser of services and solutions in the federal government.  With a government fiscal year 2014 budget of $582 billion, the 
DoD accounts for approximately 52% of the total discretionary budget and nearly 58% of contracted services.  

After a decade of uninterrupted growth, federal spending has come under pressure in recent years given continued budget 
deficits and mounting levels of debt.  Contentiousness in Congress created uncertainty about funding levels and led to a brief 
government shutdown in 2013.  This environment caused customers to delay awards and spending.  In December of 2013, Congress 
approved a two-year budget framework keeping defense spending roughly constant through 2015; based on this framework, in 
January 2014, Congress passed and the President signed appropriations for all federal government agencies for the first time in 
two years.  These developments are beginning to provide our customers with the visibility necessary to develop and actively 
execute spending plans.  Customers are now making funding and award decisions, which is a positive development for our industry. 

During the last year the government has continued to adopt policies that adversely impact the government services industry.  
Chief among these was a continued shift to using cost-plus contracts and a focus on cost in proposal evaluations among our 
customers, as well as an increasing emphasis on making awards to small businesses.  Furthermore, we expect that our customers 
will continue to be motivated to control costs. 

We expect government funding priorities will continue to evolve as we exit Afghanistan and debate the nation's strategic 
interest and objectives.  However, we believe that the federal government's spending will remain robust in key areas for which 
ManTech  is  well  positioned,  including  national  and  homeland  security  programs,  sophisticated  intelligence  gathering  and 
information sharing activities required in a dangerous world and implementation of new healthcare systems and policies.  The 
U.S. is committed to maintaining its superiority in capabilities that we support, such as cyber security, intelligence analysis and 
operations, and intelligence, surveillance and reconnaissance (ISR).  Also, with an increasing veteran population and an aging 
national population, investments in healthcare will continue.  The government is actively looking for cloud-based solutions and 
data center consolidation to save money as well as systems integration and interoperability to enable better coordination and 
communication within and among agencies and departments.  We believe we are also well positioned in these growth markets.

Our Strategy

We aspire to be recognized by customers, employees, job applicants and investors as the premier provider of technology and 
engineering services and solutions to the federal government market.  We are executing a multi-year strategy for achieving this 
objective, which is comprised of the following:

•  Provide Direct Support to Our Customers' Most Critical Missions

Even in a cost-constrained environment in which certain customers may value low cost more than technical superiority, we 
believe that our customers will continue to focus on mission and rely on their most trusted prime contractors.  Since our founding 
in 1968, we have focused on providing technology-based solutions and services for mission-critical national security programs.  
Most of our work centers around our customers' core mission as opposed to support functions.  We have several long standing 
customer relationships; many of our early customers are our customers today.  Because our personnel are on-site with, or work in 
close proximity to our customers, we understand their requirements and are often able to enhance their operations by rapidly 
identifying and developing solutions for customer-specific requirements.

The prime contractor position is increasingly important, and we have aggressively pursued new prime positions both organically 
and through acquisitions.  In fiscal year 2013, we derived 91.2% of our revenues as a prime contractor, compared to less than 50% 
just five years ago.  As a prime contractor, we are able to enhance the relationship with our customers, ensure overall program 
success, foresee emerging requirements and manage project resources.

•  Compete Aggressively on New Opportunities

We closely track our customers' requirements and funding and have built our capability and capacity to pursue the opportunities 
that arise.  We intend to capitalize on our global footprint and long-term relationships with our customers and our reputation within 
the intelligence community, DoD and other government agencies to attract new customers and to cross-sell our broad array of 
solutions  to  our  existing  customers.    Our  successful  track  record  and  technical  expertise  give  us  credibility  with  our  current 
customers and enhance our ability to gain follow-on contracts and compete for new programs.    

4

•  Build Presence in New Growth Markets

Robust  spending  on  government  technical  services  will  offer  opportunities  for  development  and  delivery  of  advanced 
technology solutions for enterprise applications and information systems.  We intend to expand our service offerings in such high 
growth program areas.  In particular, we intend to focus on providing new or improved solutions in cyber security, information 
assurance, insider threat detection, enterprise IT and health IT.  Our recent win of the Continuous Monitoring as a Service (CMaaS) 
basic purchasing agreement within the Department of Homeland Security provides an excellent opportunity to expand our leading 
cyber security skills to new customers across the federal government. 

We plan to pursue strategic acquisitions of businesses that can broaden our domain expertise and service offerings and allow 
us to establish relationships with new customers.  We have successfully acquired 23 businesses since our IPO in February 2002.  
We will continue to seek out new growth areas.  Our balance sheet and $500.0 million revolving credit facility provide us with 
ample capacity to expand our business through strategic acquisitions. 

•  Focus on Shareholder Returns

During fiscal year 2013, we generated $188.3 million in operating cash flow and paid $31.2 million in dividends to our 
shareholders.  We believe that ManTech is a compelling investment due to our regular cash dividend program, our strong competitive 
positioning and our strong balance sheet that allows us to pursue new growth opportunities as there becomes more clarity with 
respect to our end markets.

Our Solutions and Services

We combine deep domain understanding and technical capability to deliver comprehensive IT, systems engineering, technical 
and other services and solutions, primarily in support of mission critical national security programs for the intelligence community; 
DoD; and the healthcare and space communities.  We deploy our broad set of services in custom combinations to best address the 
requirements of our customers' long-term programs.  The following solution sets that we provide are aligned with the long-term 
needs of our customers: cyber security; IT modernization and sustainment; intelligence/counterintelligence solutions and support; 
systems engineering; healthcare analytics and IT; test and evaluation; C4ISR solutions and services; environmental, range and 
sustainability services; training services; and global logistics support.  

Cyber Security

Ubiquitous  security  challenges  threaten  not  just  traditional  IT,  but  also  many  other  national  security  systems;  embedded 
electronics on ground, sea and aerospace platforms; classified and law enforcement networks & systems; health IT; and systems 
providing critical civilian services. Our team of security experts tackles some of the most challenging cyber security problems 
facing the nation, such as identifying and neutralizing external cyber attacks, engineering tailored defensive security solutions and 
controls, managing security operations centers (SOCs), developing robust insider threat detection programs and creating enterprise 
vulnerability  management  programs.  We  have  provided  computer  network  operations  support  to  important  national  security 
customers for more than a decade, working across the three domains of computer network attack, defense and exploitation.  We 
provide comprehensive cyber warfare and cyber defense security solutions and services to the DoD, agencies, in the intelligence 
community, Department of State, Department of Justice and other federal agencies, as well as commercial clients.  We operate 
24/7 SOCs for several key government customers, including the departments of Justice and Agriculture and the FBI.

We are also trusted partners in the area of information assurance (IA).  Our understanding of IT security guidance and policy 
allows us to assist our customers in ensuring their programs are protected in accordance with that policy and in developing mitigation 
strategies to reduce the risks of cyber threats.  Our vulnerability assessment and penetration testing capabilities allow us to emulate 
threats to information, whether from wired or wireless networks, software applications or through social engineering.  If a customer 
is unfortunate enough to have experienced a compromise, we can deploy our incident response team, comprised in part of former 
cyber federal law enforcement agents, around the world to assist them.  

We operate the DoD IA (Cyber) Range for the Defense Information Systems Agency (DISA) and the Office of the Secretary 
of Defense (OSD) under the operational control of the Marine Corps.  In unclassified and classified venues, we provide a full 
range of services to train cyber warriors; test programs, systems and products; and exercise cyber warfighters and system operations/
procedures in a low risk/highly realistic environment to prepare for cyber warfare.  We develop operationally realistic, scalable 
and rapidly configurable environments that replicate or emulate the customer's environment.  Our DoD IA (Cyber) Range customer 
interface includes: Cyber Range infrastructure design and hosting; Cyber Range operations development; Cyber exercise support; 
Immersive Cyber environments; and real and virtual Red Team activities for providing offensive challenges to cyber defenders.   

5

Our commercial cyber security business builds upon our skills and capabilities acquired in support of federal agencies. By 
offering a full service cyber solutions capability for the commercial market, we are able to provide ManTech services which 
augment our commercial product line, and likewise offer those cyber security products to our federal customers. We currently 
provide forensics support, advanced persistent threat detection, incident response, malware analysis, threat intelligence, and threat 
management capability to clients in the financial, energy, retail and U.S. critical infrastructure sectors.

Our  solutions  also  support  unique  mission  areas  such  as  computer  forensics,  cyber  threat  analysis,  computer  crimes 
investigations, security operations center management and specialized cyber training.  We perform advanced services in the areas 
of data mining analysis, atypical data recovery techniques and data extraction.  For example, in support of a customer, we develop 
and staff a national level computer forensic laboratory and provide a broad spectrum of subject matter expertise, including reverse 
engineering and code analysis; forensic signature creation, detection and analysis; damaged media recovery; hidden data processing; 
protected data processing; forensic software development; and custom training development and implementation.  

IT Modernization and Sustainment

IT plays an increasingly central role in the missions of our defense, intelligence and federal civilian customers, and as a result, 
is an important part of many of our solution areas. We design, develop, deploy, modernize, operate and maintain IT systems and 
infrastructure as a stand-alone service offering to improve mission performance and lower costs for our government customers. 
For the Department of State, we modernize classified and unclassified networks and systems in locations around the world.  The 
backbone of our global capabilities is a comprehensive ISO 9001:2000-certified management and control system designed to 
provide best value for our customers and to lower the total cost of ownership across the systems' lifecycles.  For the Defense 
Commissary Agency, we provided Network Operations Center services to sustain its global network infrastructure and manage 
hardware and software at remote sites from headquarters.

We leverage our strong engineering discipline to aid our customers in moving their IT enterprise infrastructure and applications 
from disparate instances into cloud offerings.  The migration towards customer private secure cloud architectures is compelling 
because  it  enables  our  customers  to  integrate  their  global  IT  infrastructure  optimally,  while  still  providing  the  geo-specific 
requirements where necessary.  For a DoD customer we are consolidating multiple instances of stove-piped applications onto a 
single utility cloud backbone, allowing these legacy applications to continue supporting their mission while lowering the overall 
operations cost.

We also support the FBI's Criminal Justice Information Services (CJIS), where we are providing operations and maintenance 
support to one of the world's largest data centers.  FBI CJIS equips the law enforcement, national security and intelligence community 
with the criminal justice information they need to protect the United States while preserving civil liberties. ManTech operates, 
maintains, refreshes and enhances FBI CJIS IT systems required to process and share mission-critical information for members 
of the law enforcement community in the United States and abroad.  ManTech is sustaining systems that support millions of 
requests each day, including when police check vehicle license plates or look for a fingerprint match against the largest biometrics 
database in the world.  The mission-critical systems we support must be operational and available 24x7; we understand that the 
impact  to  police  officers,  FBI  agents,  customs  agents  and  government  agencies  nationwide  would  be  significant,  even  life-
threatening, if the systems were to go down.  Specific functions supported include IT system operations and maintenance, database 
administration, cyber security and hardware and data center support. 

Intelligence/CounterIntelligence Solutions and Support

We provide robust information technology solutions and mission support services that the national intelligence agencies and 
other classified program customers need to assure continuous operations, improve data gathering and analysis, collaborate securely 
and protect program security. 

Our network architecture planning and implementation services and systems engineering services support enterprise-wide 
network infrastructures and components that include local area network/wide area network architectures, messaging architectures, 
network  management  solutions,  directory  services  architecture  and  web  hosting.   These  services  are  provided  within  secure 
environments requiring the application of multi-level security policies across the enterprise.  For example, we developed a state-
of-the-art analytic environment that provides access to regional, national and international information with appropriate security 
level access controls, providing direct operational support to time-sensitive counterterrorism activities in support of an intelligence 
community customer.

We support strategic and tactical intelligence systems, networks and facilities across the intelligence community and DoD.  
We  develop  and  integrate  collection  and  analysis  systems  and  techniques.   We  also  provide  support  to  the  development  and 
application  of  analytical  techniques  to  counterintelligence,  Human-Intelligence  operations/training  and  counter-terrorist 
6

operations.  For example, we support intelligence operations designed to counter narcotics trafficking along our nation's southwest 
border.

Highly-classified programs, including intelligence operations and military programs, require secrecy management and security 
infrastructure services.  These services can include vulnerability assessment, exposure analysis, secrecy architecture design, security 
policy development and implementation, lifecycle acquisition program security, operations security, information assurance, Anti-
Tamper,  Export  Compliance  support,  foreign  disclosure,  system  security  engineering,  security  awareness  and  training, 
comprehensive security support services and technical certification and accreditation services.  We provide integrated security 
support for a number of programs, including the Joint Strike Fighter (JSF) Program, which presents one of the most complex 
security problem sets of any weapon system in our nation's history due to the numerous highly classified technologies incorporated 
in its design and international content in both its development and its usage.  

Systems Engineering 

Since 1968, ManTech's scientists and engineers have provided disciplined systems engineering support to a wide range of 
customers that presently includes programs and offices within the Department of Homeland Security (DHS), DoD and intelligence 
community. For example, we perform comprehensive systems engineering services to analyze, develop and integrate solutions 
for U.S. Navy hardware and software requirements across subsurface, surface, ground, air and space domains; provide acquisition 
and program management support for the DHS's Customs and Border Protection (CBP) Office of Technology, Innovation and 
Acquisition; and support current and future space launch operations for the U.S. Air Force Launch and Range Systems Wing with 
systems  engineering  and  integration  services.    We  also  provide  scientific,  engineering  and  technical  support  services  to  the 
Department of Energy's SunShot Initiative, which aims to reduce by 75% the cost of utility-scale electricity at the grid by the year 
2020.

Our proprietary systems engineering toolset, the ManTech Enterprise Framework, provides a regimented and interdisciplinary 
approach to transition from a stated need to an operationally effective and suitable system, service or capability.  Based in “Systems 
Thinking,” the framework is an overarching and proven process that integrates the full spectrum of project management, systems 
engineering and acquisition practices necessary to effectively manage a project or system over its lifecycle. Through it, we address 
a  full  360-degree  perspective  of  a  program,  including  disciplines  of  system,  software,  hardware,  acoustics,  communications, 
reliability, safety and test engineering, as well as modeling, simulation and analysis. Our long-term commitment to the systems 
engineering discipline is exemplified by our achievement of our Capability Maturity Model® Integration (CMMI) Level 3 rating 
for Software and Systems Engineering.  

Healthcare Analytics and IT

As a focused healthcare systems integrator with particular strength in federal healthcare systems, ManTech supports a wide 
range of programs that enable clinical intelligence, quality, patient and family centric care, chronic disease management, and 
comparative effectiveness research.  We deliver domain-specific capabilities, including solutions that encompass health information 
sharing and clinical analytic solutions.  Our technology solutions empower patients and providers with better, richer, and more 
timely data, care coordination solutions, and imaging management capabilities-all built on interoperable platforms to new national 
standards.    For  imaging,  informatics,  interoperability  and  integration  challenges,  our  team  provides  a  powerful  ally  in  the 
transformation of health IT.

One area of particular emphasis is the creation of a seamless medical record across the DoD and the Department of Veterans 
Affairs (VA).  The Bidirectional Health Information Exchange (BHIE) has been the primary interoperability platform between the 
DoD and the VA for many years.  Used daily by thousands of providers, it is one of the world's most comprehensive and highest 
volume Health Information Exchanges (HIEs).  The legacy BHIE system was so successful that demands placed on the system 
outgrew its original design.  ManTech helped migrate the system toward modern health IT standards by adopting the Nationwide 
Health Information Network and associated standards wherever possible.  The Virtual Lifetime Electronic Record (VLER) effort, 
which is being carried out in conjunction with the BHIE upgrade project, enables sharing not only between DoD and VA, but also 
between the government and civilian provider networks and local HIEs.  VLER relies on the Nationwide Health Information 
Network as the mechanism through which to share standards-based health data between DoD, VA and private sector partners.  
ManTech has developed VLER-Health on behalf of the DoD in conjunction with its work to upgrade the BHIE.  Functional domain 
content for BHIE and VLER-Health overlaps significantly; ManTech is integrating these two projects to share data-access methods 
and use DoD's Nationwide Health Information Network gateway.

Test and Evaluation

ManTech is a leading provider of test and evaluation services to a wide range of defense, intelligence, homeland security and 
space customers.  Our test and evaluation services are tightly linked with our systems engineering capabilities and include specific 
competencies in test engineering, preparation and planning; modeling and simulation; test range operations and management; 
systems and cyber vulnerability; and Independent Validation & Verification (IV&V).  Employing a technical staff with a wide 
range of practical experience and education, we provide our clients with the right skill sets to support and perform operational and 
developmental tests.  

We test complex and mission-critical hardware and software systems used by the Army, Navy and Marine Corps, with many 
of these customer relationships spanning more than three decades.  We have played key roles in improving the performance, 
reliability, maintainability, supportability and weapons effectiveness of all Navy in-service rotary and fixed wing platforms and 
their associated systems and ordnance.  Likewise, we maintain a facility to support Marine Corps intelligence systems research 
and development providing the associated test and evaluation required to ensure these systems meet specified requirements for 
Marines in the field.  

We perform independent tests to certify that new or upgraded systems operate in accordance with design requirements and 
interoperate with legacy systems.  For example, for the past 25 years ManTech has installed, operated and maintained a large and 
complex joint test environment for the Joint Interoperability Test Command within DISA.  Recently, we built a systems integration 
lab (SIL) for a DoD customer that enables engineers to test new hardware and software on a virtual copy of the enterprise architecture.  
Once per quarter, virtual snapshots are taken of the servers and placed in the SIL to create an accurate facsimile of the production 
environment.  We have also performed certification services for aircraft weapon systems in support of U.S. Naval Air Systems 
Command programs.    

Additionally, we are the prime contractor supporting the U.S. Army's Electronic Proving Ground at Fort Huachuca, AZ.  
ManTech provides support testing for command, control, communications, computers and intelligence, navigation and sensor 
systems for reliability, availability and maintainability, electromagnetic interference/electromagnetic compatibility and security.

Environmental, Range and Sustainability Services

ManTech  is  a  leader  in  the  fields  of  environmental,  range  and  sustainability  planning,  regulatory  compliance,  biological 
resources  and  policy  development.  In  an  increasingly  interconnected  world  with  growing  demands  for  limited  resources,  we 
provide  trusted  solutions  that  meet  today's  most  pressing  challenges  while  securing  the  future.  Our  multidisciplinary staff  of 
planners, scientists, analysts and managers brings the education, experience and expertise to develop and execute comprehensive 
sustainability  strategies  and  environmental  compliance  programs  in  support  of  government  and  industry.   We  work  with  our 
customer to manage and comply with the nation's most important environmental laws, including the National Environmental 
Policy Act, the Endangered Species Act, and the Marine Mammal Protection Act.  We also provide ocean and coastal environmental 
planning,  coastal  zone  management  planning,  biological  surveys  and  monitoring,  bioacoustics  and  noise  analysis,  habitat 
restoration, invasive species management and solid-waste compliance support.

For example, naval training and test ranges can require large areas and are often questioned for their potential impact on 
sensitive environments. In order to retain the ability to train personnel and test equipment, the Navy has developed an integrated 
program to assess the impact of its ranges and minimize impact on the environment, populated areas, shipping and navigation.  
Tactical Training Theater Assessment Program (TAP) is the Navy's comprehensive program focused on environmental planning 
and sustainability of training and test ranges worldwide.  ManTech delivers critical planning solutions to complex environmental 
and regulatory challenges in order to preserve and enhance the capabilities of Navy and Marine Corps ranges.

Also, ManTech has supported Vandenberg Air Force Base to execute its environmental planning programs for nearly 25 years.  
ManTech has a diverse background in all aspects of launch-support operations and environmental planning for the 30th Civil 
Engineering Squadron Environmental Flight.  We understand both the unique operational conditions and mission requirements of 
this installation and its tenant commands and the demands of sustaining and conserving the natural and cultural resources that are 
found at Vandenberg Air Force Base.  Our support includes a team of highly experienced biologists, ecologists and National 
Environmental Policy Act (NEPA) specialists.  ManTech's support under this program includes sensitive species management 
plans, threatened and endangered species surveys, marine mammal monitoring, invasive species control, construction monitoring, 
habitat restoration plans and implementation, predator control, biological and environmental assessments, mitigation monitoring, 
erosion control, storm water monitoring and solid waste environmental compliance. 

Training Services

After more than four decades of successful performance, ManTech’s training organizations remain consistently capable of 
meeting any training need our customers have encountered.  ManTech personnel have developed training curriculum for more 
than 150 occupational specialties, delivering several tens of thousands of hours of instructional material for use in classrooms, on 
the job, via distributable DVD, or on Enterprise Learning Management Systems such as Army Knowledge Online (AKO) and

ManTech’s own classrooms.

ManTech’s cutting edge training technology is best shown in the Cyber Security training work we are doing for the U.S. Navy 
Space and Naval Warfare Command (SPAWAR).  To meet the needs of Navy Information Assurance/Computer Network Defense 
(IA/CND) training, ManTech developed a virtualized network training system that is being recognized as the foremost training 
solution for hands-on training in Cyber defense.  This virtual system training environment (VSTE) provides a compact, mobile 
training laboratory hosting multiple suites of totally virtualized fully operational networks for student access and practice in IA/
CND system operation, administration, troubleshooting, and threat analysis.  ManTech is using this mobile system to train the 
Navy technicians aboard every ship in the U.S. Navy, the Military Sealift Command, and at the Network Operating Centers (NOCs) 
worldwide.  To support a recent critical upgrade of the Host Based Security System (HBSS), ManTech produced 10 mobile training 
systems and fielded Mobile Training Teams to successfully train 325 ships and the NOCs within 7 months.

Working hand-in-hand with SPAWAR Systems Center, Pacific, ManTech is currently implementing an Enterprise Virtual 
Training Environment (VTE) that will provide 7/24 secure access for Navy Network Security Vulnerability Technician (NSVT) 
training at the Center for Information Dominance (CID) Learning Sites at CONUS and OCONUS locations. This environment is 
expected to ultimately be made available to Navy ships and bases worldwide for IT initial, refresher and sustainment training.

We treat sales to U.S. government customers as sales within the United States, regardless of where services are performed.  

The percentage of total revenues by geographic customer for the last three years were as follows:

At December 31, 2013, our backlog was $3.9 billion, of which $1.1 billion was funded backlog.  At December 31, 2012, our 
backlog was $6.5 billion, of which $1.8 billion was funded backlog.  The decrease in our backlog primarily reflects reduced 
demand  on  contracts  related  to  Overseas  Contingency  Operations  (OCO)  resulting  from  the  accelerated  withdrawal  from 
Afghanistan.  We expect that approximately 38.9% of our total backlog will be recognized as revenues prior to December 31, 
2014.

We define backlog as our 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 indefinite delivery/indefinite quantity (ID/
IQ) contracts.  We also include an estimate of revenues for solutions that we believe we will be asked to provide in the future 
under the terms of ID/IQ contracts for which we have an established pattern of revenues.

We define 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.  
Our funded backlog does not include the full value of our 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.

Changes in the amount of our backlog and funded backlog result from potential future revenues following 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 for previously included contracts.  Changes in the amount of our funded 
backlog also are affected by the funding cycles of the government.  Our estimates of future revenues are inexact and the receipt 
and timing of any of these revenues is subject to various contingencies, many of which are beyond our control.  The actual accrual 
of revenues on programs included in backlog and funded backlog may never occur or may change because a program schedule 
could change, a program could be canceled, a contract could be modified or canceled, an option that we have assumed would be 
exercised is not exercised or initial estimates regarding the amount of services that we may provide could prove to be wrong.  For 
the same reason, we believe that period-to-period comparisons of backlog and funded backlog are not necessarily indicative of 
future revenues that we may receive.

Patents, Trademarks, Trade Secrets and Licenses

We own a limited number of patents.  We also maintain a number of trademarks and service marks to identify and distinguish 
the goods and services we offer.  While we believe protecting our patents, marks, trade secrets and vital confidential information 
is important, our business does not depend on the existence or protection of such intellectual property.

Seasonality

Our business is not seasonal. However, it is not uncommon for federal government agencies to award extra tasks or complete 
other contract actions in the weeks before the end of the federal government's fiscal year (which is September 30) in order to avoid 
the loss of unexpended fiscal year funds.  Additionally, our quarterly results are impacted by the number of working days in a 
given quarter.  There are generally fewer working days for our employees to generate revenues in the first and fourth quarters of 
our fiscal year.

Competition

Our key competitors currently include divisions of large defense contractors, as well as a number of mid-size U.S. government 
contractors with specialized capabilities.  Because of the diverse requirements of U.S. government customers and the highly 
competitive nature of large procurements, we frequently collaborate with these and other companies to compete for large contracts 
and bid against these companies in other situations.  Increasingly, cost has become the principal method of competition on many 
procurements (rather than technical superiority).

Risk Factors 

Forward-Looking and Cautionary Statements

Set forth below are the risks that we believe are material to investors who purchase our common stock. You should carefully 
consider the following risks together with the other information contained in or incorporated by reference into this Annual Report 
on Form 10-K, including our consolidated financial statements and notes thereto.  The risks described below are not the only risks 
facing us.  Additional risks and uncertainties not currently known to us, or those we currently deem to be immaterial, may also 
materially and adversely affect our business, financial condition or results of operations.  This section contains forward-looking 
statements. You should refer to the explanation of the qualification and limitations of forward-looking statements set forth at the 
beginning of this Annual Report.

Risks Related to Our Business 

We depend on contracts with the U.S. federal government for substantially all of our revenues.  If our relationships with the 
federal government were harmed, our business, future revenues and growth prospects could be adversely affected. 

We derive the vast majority of our revenues from our federal government customers.  We expect that federal government 
contracts will continue to be the primary source of our revenues for the foreseeable future.  Our business, prospects, financial 
condition or operating results could be materially harmed if:

•  We are suspended or debarred from contracting with the federal government or a significant government agency;

•  Our reputation or relationship with government agencies is impaired; or 

•  The government ceases to do business with us, or significantly decreases the amount of business it does with us. 

Among the key factors in maintaining our relationships with federal government agencies are our performance on individual 
contracts and task orders, the strength of our professional reputation and the relationships of our senior management with our 
customers. 

Federal government spending levels for programs we support may change or be delayed in a manner that adversely affects our 
future results and limits our growth prospects. 

Our business depends upon continued federal government expenditures on intelligence, defense and other programs that we 
support.  These expenditures have not remained constant over time.  Over the last couple years, in the face of growing national 
debt and long-term fiscal challenges facing the nation, spending levels for federal government programs generally, and in particular 
the U.S. defense budget, have come under pressure.  Federal budget constraints may affect future levels or timing of expenditures, 
place pressure on operating margins in our industry, and shift expenditures to programs in areas where we do not currently provide 
services, thereby adversely impacting our future results of operations.  A reduction in the amount of services that we are contracted 
to provide, or incorporation of less favorable terms in existing or future contracts, could cause an adverse impact on our business 
and future results of operations.

12

The failure by Congress to approve budgets on a timely basis for the federal agencies we support could delay procurement of 
our services and solutions and cause us to lose future revenues. 

On an annual basis, Congress must approve budgets that govern spending by the federal agencies that we support.  In years 
when Congress is not able to complete its budget process before the end of the federal government's fiscal year on September 30, 
Congress  typically  funds  government  operations  pursuant  to  a  continuing  resolution.   A  continuing  resolution  allows  federal 
government agencies to operate at spending levels approved in the previous budget cycle.  When the U.S. government operates 
under a continuing resolution, it may delay funding we expect to receive from customers on work we are already performing and 
will likely result in new initiatives being delayed or in some cases canceled.  The federal government's failure to complete its 
budget process, or to fund government operations pursuant to a continuing resolution, may result in a federal government shutdown, 
such as that which occurred during the 2013 fiscal year.

The competitive bidding process can impose substantial constraints and costs upon us and we may lose revenues, or our earnings 
and profitability may be adversely impacted, if we fail to compete effectively, if we are required to reduce our price in order to 
compete effectively, or if there are delays caused by protests or challenges of contract awards.  

We derive significant revenues from federal government contracts that are awarded through a competitive bidding process.  
We expect that a significant portion of our future business will continue to be awarded through competitive bidding. Competitive 
bidding presents a number of risks, including: 

• 

Incurring expense and delays due to competitor's protest or challenge of contract awards made to us, including the 
risk that any such protest or challenge could result in the resubmission of bids on modified specifications, or in the 
termination, reduction or modification of the awarded contract, which may result in reduced profitability;

•  Changes to customer bidding practices or government reform of its procurement practices, which may alter the 

prescribed contract requirements relating to contract vehicles, contract types and consolidations; 

•  Changes in policy and goals by the government providing set-aside funds to small business, disadvantaged businesses 

and other socio-economic requirements in the allocation of contracts;

• 

• 

Spending substantial cost and managerial time and effort to prepare bids and proposals for contracts that may not be 
awarded to us, which may result in reduced profitability;

Failing to accurately estimate the resources and cost structure that will be required to service any contract we are 
awarded; and

•  Bidding on programs in advance of the completion of their design, which may result in unforeseen difficulties in 

execution, cost overruns, or, in the case of unsuccessful competition, the loss of committed costs.

Additionally, many of our customers have increasingly focused on cost as a key component of the procurement evaluation 
process.  This focus has increased competitive pricing pressures and resulted in a reduction to the profits we expect to earn on our 
federal government contracts.  Specifically, the use by the federal government of a lowest price/technically acceptable standard 
for contract awards, may require us to decrease the margin by which we expect our bid price to exceed our costs. 

If we are unable to win particular contracts that are awarded through the competitive bidding process, in addition to the risk 
that our operating results may be adversely affected, we may be unable to operate in the market for services that are provided 
under those contracts for a number of years.  

13

Our earnings and profitability may be adversely affected if we do not accurately estimate the expenses, time and resources 
necessary to satisfy some of our contractual obligations. 

We enter into three types of federal government contracts for our services: cost-reimbursable, time-and-materials and fixed-
price.  Our customers have increasingly procured our services under cost-reimbursable contracts, which tend to offer lower margin 
opportunities than other contract types.  For our last three fiscal years, we derived revenues from such contracts as follows: 

Cost-reimbursable

Fixed-price

Time-and-materials

Year Ended December 31,

16.2%

32.8%

100.0%

33.6%

15.9%

50.5%

100.0%

Each of these types of contracts, to varying degrees, involves some risk that we could underestimate our cost of fulfilling the 

contract, which may reduce the profit we earn or lead to a financial loss on the contract.

•  Under cost-reimbursable contracts, we are 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-reimbursable contract are within 
the contract ceiling and allowable under the terms of the contract and applicable regulations, we are entitled to 
reimbursement of our costs, plus a profit.  However, if our costs exceed the ceiling or are not allowable under the 
terms of the contract or applicable regulations, we may not be able to recover those costs.  In particular, there is 
increasing focus by the federal government on the extent to which contractors are able to receive reimbursement for 
employee compensation.  

•  Under fixed-price contracts, we perform 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 we bear the 
impact of cost overruns, which could result in increased costs and expenses.  Because we assume such risk, an 
increase in the percentage of fixed-price contracts in our contract mix, whether caused by a shift by the federal 
government toward a preference for fixed-price contracts or otherwise, could increase the risk that we suffer losses 
if we underestimate the level of effort required to perform the contractual obligations.

•  Under time-and-material contracts, we are reimbursed for labor at negotiated hourly billing rates and for certain 
expenses.  We assume financial risk on time-and-material contracts because we assume the risk of performing those 
contracts at negotiated hourly rates.

Our profits could be adversely affected if our costs under any of these contracts exceed the assumptions we used in bidding 

for the contract.  

Many of our federal government customers execute their procurement budgets through multiple award contracts under which 
we are required to compete for post-award orders, or for which we may not be eligible to compete, potentially limiting our 
ability to win new contracts and increase revenues.

Budgetary pressures and reforms in the procurement process have caused many U.S. federal government customers to purchase 
goods and services through multiple award ID/IQ contracts and other multiple award and/or government wide acquisition contract 
vehicles.  These contract vehicles require that we  make sustained post-award efforts to obtain task orders under the relevant 
contract.  There can be no assurance that we will obtain revenues or otherwise sell successfully under these contract vehicles.  Our 
failure to compete effectively in this procurement environment could harm our operating results.  

14

Federal government contracts contain provisions giving government customers a variety of rights that are unfavorable to us, 
including the ability to terminate a contract at any time for convenience. 

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.  These provisions may allow the government to: 

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

•  Reduce orders under, or otherwise 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 multi-year contracts or issue task orders in connection with multiple award 

contracts;

• 

• 

• 

Suspend or debar us from doing business with the federal government or with a government agency;

Prohibit future procurement awards with a particular agency as a result of a finding of an organizational conflict of 
interest based upon prior related work performed for the agency that would give a contractor an unfair advantage 
over competing contractors;

Subject  the  award  of  contracts  to  protest  by  competitors,  which  may  require  the  contracting  federal  agency  or 
department to suspend our performance pending the outcome of the protest and may also result in a requirement to 
resubmit offers for the contract or in the termination, reduction or modification of the awarded contract;

•  Terminate our facility security clearances and thereby prevent us from receiving classified contracts;

•  Claim rights in products and systems produced by us; and

•  Control or prohibit the export of our products and services.

If the government terminates a contract for convenience, we may recover only our incurred or committed costs, settlement 
expenses and profit on work completed prior to the termination.  If the government terminates a contract for default, we may not 
even recover those amounts and instead may be liable for excess costs incurred by the government in procuring undelivered items 
and services from another source.  If one of our government customers were to unexpectedly terminate, cancel or decline to exercise 
an option to renew one or more of our significant contracts or programs, our revenues and operating results would be materially 
harmed. 

We may not receive the full amount authorized under our contracts and we may not accurately estimate our backlog, which 
could adversely affect our future revenues and growth prospects. 

As of December 31, 2013, our backlog was $3.9 billion, of which $1.1 billion was funded.  Backlog is our 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 ID/IQ contracts.  Backlog also includes estimates of revenues for solutions that we 
believe we will be asked to provide in the future under the terms of ID/IQ contracts for which we have an established pattern of 
revenues.  Our estimates are based on our experience using such vehicles and similar contracts; however, we cannot assure that 
all, or any, of such estimated contract revenues will be recognized as revenues.  

Historically, we have not realized all of the revenue included in our total backlog, and we may not realize all of the revenue 
included in our total backlog in the future.  There is a somewhat higher degree of risk in this regard with respect to unfunded 
backlog, since it contains management's estimate of amounts expected to be realized on unfunded contract work that may never 
be realized as revenues.  In addition, there can be no assurance that our backlog will result in actual revenue in any particular 
period, or at all, because the actual receipt, timing and amount of revenue under contracts included in backlog are subject to 
numerous uncertainties, many of which are beyond our control.  Furthermore, the actual receipt of revenue from contracts included 
in backlog may never occur or may be delayed because: a program schedule could change or the program could be canceled; a 
contract's funding or scope could be reduced, modified, delayed or terminated early, including as a result of a lack of appropriated 
funds or as a result of cost cutting initiatives and other efforts to reduce federal government spending.  For example, during the 
second half of 2013, as a result of changing mission priorities on OCO programs that we support, our ability to recognize revenue 
15

on contracts that were included in backlog was adversely affected.  If we fail to realize as revenues those amounts included in our 
backlog, our future revenues and growth prospects may be adversely affected.  

We face aggressive competition that can impact our ability to obtain contracts and therefore affect our future revenues and 
growth prospects. 

We operate in highly competitive markets and generally encounter intense competition to win contracts.  We compete with 
larger companies that have greater name recognition, financial resources and larger technical staffs.  We also compete with smaller, 
more specialized companies that are able to concentrate their resources on particular areas.  To remain competitive, we must 
provide superior service and performance on a cost-effective basis to our customers.  Our competitors may be able to provide our 
customers with different or greater capabilities or better contract terms than we can provide, including technical qualifications, 
past contract experience, geographic presence, price and the availability of qualified professional personnel.  In particular, increased 
efforts by our competitors to meet federal government requirements for efficiency and cost reduction may necessitate that we 
become more competitive with respect to price, and thereby potentially reduce our profit margins, in order to win or maintain 
contracts.  In addition, our competitors may consolidate or establish teaming or other relationships among themselves or with third 
parties to increase their ability to address customers' needs.

Acquisitions could result in operating difficulties, dilution or other adverse consequences to our business.  

One of our key operating strategies is to selectively pursue acquisitions.  We have made a number of acquisitions in the past 
and we expect that a portion of our future revenues will continue to come from such transactions.  We evaluate potential acquisitions 
on an ongoing basis.  Our acquisitions strategy poses many risks, including:

•  As a result of an acquisition, we may need to record write-downs from future impairments of intangible assets, which 

could reduce our future reported earnings;

•  We may not be able to identify suitable acquisition candidates at prices we consider attractive;

•  We may not be able to compete successfully for identified acquisition candidates, complete future acquisitions or 

accurately estimate the financial effect of acquisitions on our business;

• 

Future acquisitions may require us to issue common stock or spend significant cash, resulting in dilution of ownership 
or additional leverage;

•  We may have difficulty retaining an acquired company's key employees or customers;

•  We may have difficulty integrating acquired businesses, resulting in unforeseen difficulties, such as incompatible 

accounting, information management or other control systems; and 

•  Acquisitions may disrupt our business or distract our management from other responsibilities.

In connection with any acquisition that we make, there may be liabilities that we fail to discover or that we inadequately 
assess.  Acquired entities may not operate profitably or result in improved operating performance.  Additionally, we may not realize 
anticipated synergies.  If our acquisitions perform poorly, our business and financial results could be adversely affected.

We have substantial investments in recorded goodwill and changes in future business conditions could cause these investments 
to become impaired, requiring substantial write-downs that would reduce our operating income and impact our financial 
position.

As of December 31, 2013, our goodwill was $752.9 million.  The amount of our recorded goodwill may substantially increase 
in the future as a result of any acquisitions that we make.  We evaluate the recoverability of recorded goodwill amounts annually, 
or when evidence of potential impairment exists.  Impairment analysis is based on several factors requiring judgment and the use 
of estimates, which are inherently uncertain and based on assumptions that may prove to be inaccurate.  Additionally, material 
changes in our financial outlook, as well as events outside of our control, such as deteriorating market conditions for companies 
in our industry, may indicate a potential impairment.  When there is an impairment, we are required to write down the recorded 
amount of goodwill, which is reflected as a charge against operating income.  During the fourth quarter of 2013, we determined 
that indicators of an impairment existed in one of our business units.  As a result we conducted an interim goodwill impairment 
analysis and have recorded a non-cash goodwill impairment charge of $118.4 million for the period ending December 31, 2013.  

16

If we fail to comply with complex procurement laws and regulations, we could lose business and be liable for various penalties 
or sanctions. 

We must comply with laws and regulations relating to the formation, administration and performance of federal government 
contracts.  These laws and regulations affect how we conduct business with our federal government customers. In complying with 
these laws and regulations, we may incur additional costs.  Non-compliance could result in the imposition of fines and penalties, 
including contractual damages.  Among the more significant laws and regulations affecting our business are the following: 

•  The Federal Acquisition Regulation, which comprehensively regulates the formation, administration and performance 

of federal government contracts; 

•  The Truth in Negotiations Act, which requires certification and disclosure of all cost and pricing data in connection 

with contract negotiations;

•  The Cost Accounting Standards and Cost Principles, which impose accounting requirements that govern our right 

to reimbursement under certain cost-based federal government contracts;

•  Laws, regulations and executive orders restricting the use and dissemination of information classified for national 

security purposes and the export of certain products, services and technical data;

•  U.S. export controls, which apply when we engage in international work; and

•  The Foreign Corrupt Practices Act. 

Failure  to  comply  with  these  laws  and  regulations  can  lead  to  severe  penalties,  both  civil  and  criminal,  and  can  include 

debarment from contracting with the U.S. government. 

Our contracting agency customers periodically review our compliance with procurement laws and regulations, as well as our 
performance under the terms of our federal government contracts.  If a government review or investigation uncovers improper or 
illegal activities, we may be subject to civil or criminal penalties or administrative sanctions, including: 

•  Termination of contracts; 

• 

Forfeiture of profits;

•  Cost associated with triggering of price reduction clauses;

• 

• 

• 

Suspension of payments;

Fines; and

Suspension or debarment from doing business with federal government agencies.

Additionally, the civil False Claims Act provides for potentially substantial civil penalties where, for example, a contractor 
presents a false or fraudulent claim to the government for payment or approval.  Actions under the civil False Claims Act may be 
brought by the government or by other persons on behalf of the government (who may then share a portion of any recovery).

If we fail to comply with these laws and regulations, we may also suffer harm to our reputation, which could impair our ability 
to win awards of contracts in the future or receive renewals of existing contracts.  If we are subject to civil and criminal penalties 
and administrative sanctions or suffer harm to our reputation, our current business, future prospects, financial condition or operating 
results could be materially harmed. 

17

The federal government may change its procurement or other practices in a manner adverse to us.

The federal government may change its procurement practices or adopt new contracting laws, rules or regulations.  Any such 
change could potentially place greater pressure on our profit margins, and could materially harm our operating results.  Additionally, 
aspects of the federal government's procurement system, such as the number of acquisition personnel available to support the 
workload imposed by an increasing number of protests, could exacerbate delays in the procurement decision making process, thus 
delaying our ability to generate revenues from proposals and awards.  The federal government could also adopt new socio-economic 
requirements or policies favoring small businesses or disadvantaged firms, which could reduce our revenue opportunities.  Any 
new contracting methods could be costly or administratively difficult for us to satisfy and, as a result, could cause actual results 
to differ materially and adversely from those anticipated.  

Failure to maintain strong relationships with other contractors could result in a decline in our revenues. 

For the years ended December 31, 2013 and 2012, we derived 8.8% and 10.1% of our revenues, respectively, from contracts 
in which we acted as a subcontractor to other contractors.  Additionally, where we are named as a prime contractor, we may 
sometimes enlist other companies to perform some services under the contract as subcontractors.  We expect to continue to depend 
on such relationships with other contractors for a portion of our revenues for the foreseeable future.  Our business, prospects, 
financial condition or operating results could be harmed if other contractors eliminate or reduce their contracts or joint venture 
relationships with us because they choose to establish relationships with our competitors; they choose to directly offer services 
that compete with our business; we choose to directly compete with them for services; the government terminates or reduces these 
other contractors' programs; or the government does not award them new contracts.  

Unfavorable federal government audits or results of other investigations could subject us to penalties or sanctions, adversely 
affect our profitability, harm our reputation and relationships with our customers or impair our ability to win new contracts. 

The Defense Contract Audit Agency (DCAA) and other government agencies routinely audit and investigate government 
contracts and contractor systems.  These agencies review a contractor's performance on its contract, cost structure and compliance 
with applicable laws, regulations and standards.  The DCAA also reviews the adequacy of, and a contractor's compliance with, 
its  internal  control  systems  and  policies,  including  the  contractor's  accounting,  purchasing,  estimating,  compensation  and 
management information systems.  Allegations of impropriety or deficient controls could harm our reputation or influence the 
award of new contracts.  Any costs found to be improperly allocated to a specific contract will not be reimbursed, while such costs 
already reimbursed must be refunded.  In recent years, U.S. government contractors have faced increased scrutiny by the DCAA 
and other U.S. government agencies.  For example, among other matters, the DCAA has begun to focus on the strict adherence 
by technology support contractors to labor qualification requirements contained in the terms of federal government contracts that 
we support.  If any of our internal control systems or policies is found non-compliant or inadequate, payments may be withheld 
or suspended under our contracts or we may be subjected to increased government scrutiny and approval requirements that could 
delay or adversely affect our ability to invoice and receive timely payment on our contracts, perform contracts or compete for 
contracts with the U.S. government.  As a result, a DCAA audit could materially affect our competitive position and result in a 
substantial adjustment to our revenues.  DCAA has completed our incurred cost audits through 2005, with no material adjustments.  
While we believe that the vast majority of incurred costs will be approved upon final audit, we do not know the outcome of any 
future audits and adjustments and, if any future audit adjustments exceed our estimates, our profitability could be adversely affected. 

U.S. government contractors are subject to a greater risk of investigation, criminal prosecution, civil fraud, whistleblower 
lawsuits  and  other  legal  actions  and  liabilities  than  companies  with  solely  commercial  customers.    In  addition  to  increased 
investigation by the DCAA, contractors that provide support services to U.S. forces in Southwest Asia have come under increasing 
scrutiny by agency inspectors general, other government auditors and congressional committees.  If a government audit or other 
investigation uncovers improper or illegal activities, we 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.  More generally, increased scrutiny and investigation into business practices and into 
major programs supported by contractors may lead to increased legal costs and may harm our reputation and profitability if we 
are among the targeted companies, regardless of the underlying merit of the allegations being investigated.

Internal system or service failures, including those resulting from cyber or other security threats, could disrupt our business 
and impair our ability to effectively provide our services to our customers, which could damage our reputation and have a 
material adverse effect on our business and results of operations.

We create, implement and maintain information technology and engineering systems, and provide services that are often 
critical to our customers' operations, some of which involve classified or other sensitive information in intelligence, national 
security and other classified or sensitive customer functions.  As a result, we are subject to systems or service failures, not only 
18

resulting from our own failures or the failures of third-party service providers, natural disasters, power shortages or terrorist attacks, 
but also from continuous exposure to cyber and other security threats, including computer viruses, attacks by computer hackers 
or physical break-ins.  In particular, as a U.S. government contractor, we face a heightened risk of a security breach or disruption 
with respect to classified or other sensitive information resulting from an attack by computer hackers, foreign governments or 
cyber terrorists.  Many government contractors have been the target of these types of attacks in the past and future attacks are 
likely to occur.  If successful, these types of attacks on our network or other systems or service failures could have a material 
adverse effect on our business and results of operations, due to, among other things, the loss of customer or proprietary data, 
interruptions or delays in our customers' businesses and damage to our reputation.  In addition, the failure or disruption of our 
systems, communications or utilities could cause us to interrupt or suspend our operations, which could have a material adverse 
effect on our business and results of operations.  

If our systems, services or other applications have significant defects or errors, are successfully attacked by cyber and other 

security threats, suffer delivery delays or otherwise fail to meet our customers' expectations, we may: 

• 

• 

• 

• 

• 

• 

• 

• 

lose revenue due to adverse customer reaction;

be required to provide additional services to a customer at no charge;

incur additional costs related to monitoring and increasing our cyber security;

lose revenue due to the deployment of internal staff for remediation efforts instead of customer assignments;

receive negative publicity, which could damage our reputation and adversely affect our ability to attract or retain 
customers;

be unable to successfully market services that are reliant on the creation and maintenance of secure information 
technology systems to U.S. government, international and commercial customers;

suffer  claims  for  substantial  damages,  particularly  as  a  result  of  any  successful  network  or  systems  breach  and 
exfiltration of customer information; or 

incur significant costs complying with applicable federal or state law, including laws governing protection of  personal 
information.

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

Our errors and omissions 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 us could seriously harm our business.  Even if not successful, these claims could result in significant 
legal and other costs, may be a distraction to our management and may harm our customer relationships.

Security breaches in customer systems could adversely affect our business. 

Many of the programs we support and systems we develop, install and maintain involve managing and protecting information 
involved in intelligence, national security and other classified or sensitive customer functions.  While we have programs designed 
to comply with relevant security laws, regulations and restrictions, a security breach in one of these systems could cause serious 
harm to our business, damage our reputation and prevent us from being eligible for further work on critical systems for our current 
customers or for other federal government customers generally.  Losses that we could incur from such a security breach could 
exceed the policy limits that we have for errors and omissions and product liability insurance coverage.  Damage to our reputation 
or limitations on our eligibility for additional work resulting from a security breach in one of the systems we develop, install and 
maintain could materially reduce our revenues.

If we fail to recruit and retain skilled employees or employees with the necessary skill sets or security clearances, we might not 
be able to perform under our contracts or win new business and our growth may be limited. 

To be competitive, we must have employees who have advanced information technology and technical services skills and 
who work well with our customers in a government or defense-related environment.  Often, these employees must have some of 
the highest security clearances in the United States.  These employees are in great demand and are likely to remain a limited 
resource in the foreseeable future.  Recruiting, training and retention costs can place significant demands on our resources.  If we 
are unable to recruit and retain a sufficient number of these employees, our ability to maintain and grow our business could be 
negatively impacted.  If we are required to engage larger numbers of contracted personnel, our profit margins could be adversely 
affected.  In addition, some of our contracts contain provisions requiring us to commit to staff a program with certain personnel 
the customer considers key to our successful performance under the contract.  In the event we are unable to provide these key 
personnel or acceptable substitutions, the customer may terminate the contract and we may not be able to recover certain incurred 
costs. 

Our business depends upon obtaining and maintaining required security clearances. 

Many of our federal government contracts require our employees to maintain various levels of security clearances and we are 
required to maintain certain facility security clearances complying with the Department of Defense and intelligence community 
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  our  employees  are  unable  to  obtain  or  retain  security 
clearances or if our employees who hold security clearances terminate employment with us, the customer whose work requires 
cleared employees could terminate the contract or decide not to renew it upon its expiration.  In addition, we expect that many of 
the contracts on which we will bid will require us to demonstrate our ability to obtain facility security clearances and perform 
work with employees who hold specified types of security clearances.  To the extent we are not able to obtain facility security 
clearances or engage employees with the required security clearances for a particular contract, we may not be able to bid on or 
win new contracts, or effectively re-bid on expiring contracts. 

Covenants in the instruments governing our indebtedness may restrict our financial and operating flexibility. 

We maintain a credit agreement with a syndicate of lenders led by Bank of America, N.A., as administrative agent.  The credit 
agreement provides for a $500.0 million revolving credit facility.  The maturity date for the credit agreement is October 12, 2016.  
The  terms  of  the  credit  agreement  permit  prepayment  and  termination  at  any  time,  subject  to  certain  conditions.   The  credit 
agreement requires the Company to comply with specified financial covenants, including the maintenance of certain consolidated 
total leverage ratios and a certain fixed charge coverage ratio.  The credit agreement also contains various covenants, including 
affirmative covenants with respect to certain reporting requirements and maintaining certain business activities, and negative 
covenants that, among other things, may limit or impose restriction on ability to incur liens, incur additional indebtedness, make 
investments, make acquisitions and undertake certain other actions.

We have $200.0 million in aggregate principal amount of 7.25% senior unsecured notes due April 15, 2018.  These 7.25% 
senior unsecured notes were issued at 100% of the aggregate principal amount and are effectively subordinate to our existing and 
future senior secured debt (to the extent of the value of the assets securing such debt), including any debt outstanding under our 
revolving credit facility.  We have determined that we will redeem these notes in April 2014 in accordance with their terms.  Until 
the  redemption  of  the  notes,  the  indenture  governing  these  notes  contains  customary  events  of  default,  as  well  as  restrictive 
covenants, which may limit our ability to: pay dividends and distributions; repurchase equity; prepay subordinated debt or make 
certain investments; incur additional debt or issue certain disqualified stock and preferred stock; incur liens on assets; merge or 
consolidate with another company or sell all or substantially all assets; and allow to exist certain control provisions.  

As a result of such covenants and restrictions in the instruments governing our indebtedness, we will be limited in how we 
conduct  our  business  and  we  may  be  unable  to  raise  additional  debt  or  equity  financing  to  take  advantage  of  new  business 
opportunities.  In addition, our ability to satisfy the financial ratios required by our instruments of indebtedness can be affected 
by events beyond our control and we cannot assure you that we will meet these ratios.  We cannot assure you that we will be able 
to maintain compliance with these covenants in the future and, if we fail to do so, we may be in default under our revolving credit 
facility or the indenture, and we may be prohibited from undertaking actions that are necessary or desirable to maintain and expand 
our business. 

Default under our revolving credit facility could allow the lenders to declare all amounts outstanding to be immediately due 
and payable.  We have pledged substantially all of our assets to secure the debt under our revolving credit facility.  If the lenders 
declare amounts outstanding under the revolving credit facility to be due, the lenders could proceed against those assets.  Any 
event of default, therefore, could have a material adverse effect on our business if the creditors determine to exercise their rights. 
20

Default under the indenture governing our 7.25% senior unsecured notes will allow either the trustee or the holders of at least 
25% in principal amount of the then outstanding 7.25% senior unsecured notes to accelerate, or in certain cases, will automatically 
cause the acceleration of, the amounts due under the 7.25% senior unsecured notes.  Any event of default, therefore, could have 
a material adverse effect on our business if the amounts due are accelerated. 

Our level of indebtedness could materially adversely affect our ability to generate sufficient cash to fulfill our obligations under 
our outstanding indebtedness, our ability to react to changes in our business and our ability to incur additional indebtedness 
to fund future needs.

Our level of indebtedness increases the possibility that we may be unable to generate cash sufficient to pay, when due, the 
principal of, interest on or other amounts due in respect of our indebtedness.  Our indebtedness, combined with our other financial 
obligations and contractual commitments, could: 

•  make it more difficult for us to satisfy our obligations with respect to our indebtedness and any failure to comply 
with the obligations under any of our debt instruments, including restrictive covenants, could result in an event of 
default under the indenture governing the notes, our revolving credit facility or any agreements governing other 
indebtedness;

• 

• 

• 

• 

require us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness, thereby 
reducing funds available for working capital, capital expenditures, acquisitions, research and development and other 
corporate purposes;

increase  our  vulnerability  to  adverse  economic  and  industry  conditions,  which  could  place  us  at  a  competitive 
disadvantage compared to competitors that have relatively less indebtedness;

limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate; and 

limit our ability to borrow additional funds, or to dispose of assets to raise funds, if needed, for working capital, 
capital expenditures, acquisitions, research and development and other corporate purposes.

Subject to the restrictions in our revolving credit facility and the indenture governing our senior notes, we may incur significant 
additional indebtedness.  If we incur a substantial amount of additional indebtedness, the related risks that we face could become 
more significant.  Additionally, the terms of any future debt that we may incur may impose requirements or restrictions that further 
affect our financial and operating flexibility or subject us to other events of default.

If our subcontractors or joint venture partners fail to perform their contractual obligations, our performance and reputation 
as a prime contractor and our ability to obtain future business could suffer. 

As a prime contractor, we often rely significantly upon other companies as subcontractors to perform work we are obligated 
to perform for our customers.  If one or more of our subcontractors fail to perform satisfactorily the agreed-upon services on a 
timely basis, or violate government contracting policies, laws or regulations, our ability to perform our obligations or meet our 
customers' expectations as a prime contractor may be compromised.  In some cases, we have limited involvement in the work 
performed by the subcontractors but are nevertheless responsible for such work.  In extreme cases, performance or other deficiencies 
on the part of our subcontractors could result in a customer terminating our contract for default.  A termination for default could 
expose us to a liability for the agency's costs of reprocurement, damage our reputation and hurt our ability to compete for future 
contracts and task orders. 

Additionally, we often enter into joint ventures so that we can jointly bid and perform on a particular project.  The success of 
these and other joint ventures depends, in large part, on the satisfactory performance of the contractual obligations by our joint 
venture partners.  If our partners do not meet their obligations, the joint ventures may be unable to adequately perform and deliver 
their contracted services.  Under these circumstances, we may be required to make additional investments and provide additional 
services to ensure the adequate performance and delivery of the contracted services. These additional obligations could result in 
reduced profits or, in some cases, significant losses for us with respect to the joint venture, which could also affect our reputation 
in the industries we serve.

21

Our overall profit margins on our contracts may decrease and our results of operations could be adversely affected if materials 
and subcontract revenues grow at a faster rate than labor-related revenues.

Our revenues are generated both from the efforts of our employees (labor-related revenues) and from the receipt of payments 
for the cost of materials and subcontracts we use in connection with performing our services (materials and subcontract revenues).  
Generally, our materials and subcontract revenues have lower profit margins than our labor-related revenues.  If our materials and 
subcontract revenues grow at a faster rate than labor-related revenues, our overall profit margins may decrease and our profitability 
could be adversely affected.

Our business operations involve considerable risks and hazards. An accident or incident involving our employees or third 
parties could harm our reputation, affect our ability to compete for business, and if not adequately insured or indemnified, 
could adversely affect our results of operations and financial condition.

Our business involves providing services that require some of our employees to operate in countries that may be experiencing 
political unrest, war or terrorism.  As a result, during the course of such deployments we are exposed to liabilities arising from 
accidents or incidents involving our employees or third parties.  Any of these types of accidents or incidents could involve significant 
potential injury or other claims by employees and/or third parties.  It is also possible that we will encounter unexpected costs in 
connection with additional risks inherent in sending our employees to dangerous locations, such as increased insurance costs, as 
well as the repatriation of our employees or executives for reasons beyond our control. 

We maintain insurance policies that mitigate risk and potential liabilities related to our operations.  Our insurance coverage 
may not be adequate to cover those claims or liabilities, and we may be forced to bear substantial costs from an accident or incident.  
Substantial claims in excess of our related insurance coverage could adversely affect our operating performance and may result 
in additional expenses and possible loss of revenues.

Furthermore, any accident or incident for which we are liable, even if fully insured, may result in negative publicity that could 
adversely affect our reputation among our customers and the public, which could result in us losing existing and future contracts 
or make it more difficult to compete effectively for future contracts.  This could adversely affect our operating performance and 
may result in additional expenses and possible loss of revenues.

Our employees or subcontractors may engage in misconduct or other improper activities, which could cause us to lose customers 
or affect our ability to contract with the federal government. 

Because we are a government contractor, should an employee or subcontractor commit fraud or should other misconduct 
occur, such occurrences could have an adverse impact on our business and reputation.  Misconduct by employees, subcontractors 
or joint venture partners could involve intentional failures to comply with federal laws including: federal government procurement 
regulations; requirements for handling of sensitive or classified information; the terms of our contracts; or proper time-keeping 
practices.  These actions could lead to civil, criminal and/or administrative penalties (including fines, imprisonment, suspension 
and/or debarment from performing federal government contracts) and harm our reputation.  The precautions we take to prevent 
and detect such activity may not be effective in controlling unknown or unmanaged risks or losses.   

We face risks associated with our international business.

Our business operations are subject to a variety of risks associated with conducting business internationally, including:

•  Changes in or interpretations of foreign laws or policies that may adversely affect the performance of our services;

• 

• 

Political instability in foreign countries;

Imposition of inconsistent laws or regulations;

•  Conducting business in places where laws, business practices and customs are unfamiliar or unknown;

• 

Imposition of limitations on or increase of withholding and other taxes on payments by foreign subsidiaries or joint 
ventures; and

•  Compliance  with  a  variety  of  U.S.  laws,  including  the  Foreign  Corrupt  Practices Act  and  U.S.  export  control 

regulations, by us or subcontractors.

22

Although such risks have not significantly impacted our business to date, we do not know the impact that these regulatory, 

geopolitical and other factors could have on our business in the future.

Risks Related to Our Stock

Our quarterly operating results may fluctuate. 

Our quarterly revenues and operating results may fluctuate as a result of a number of factors, many of which are outside of 
our control.  For these reasons, comparing our operating results on a period-to-period basis may be of limited significance in some 
cases, and as such, you should not rely on our past results as an indication of our future performance.  While our financial results 
may be negatively affected by any of the risk factors identified in this section of our Form 10-K, a number of factors could cause 
our revenues, cash flows and operating results to vary from quarter-to-quarter, including: 

•  Timing of award or performance incentive fee notices;

• 

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;

•  Reallocation of funds to customers due to priority;

•  Timing of significant bid and proposal costs;

•  Variable purchasing patterns under government contracts, blanket purchase agreements and ID/IQ contracts;

• 

• 

Seasonal or quarterly fluctuations in our workdays and staff utilization rates;

Strategic decisions by us or our competitors, such as acquisitions, divestitures, spin-offs and joint ventures;

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

procurement;

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

and 

•  Changes in the volume of purchase requests from customers for equipment and materials.

Because a relatively large amount of our expenses are fixed, cash flows from our operations may vary significantly as a result 
of changes in the volume of services provided under existing contracts and the number of contracts that are commenced, completed 
or terminated during any quarter.  We incur significant operating expenses during the start-up and early stages of large contracts 
and typically we do not receive corresponding payments in that same quarter.  We may also incur significant or unanticipated 
expenses when a contract expires, terminates or is not renewed. 

We may change our dividend policy in the future.

The Company has maintained a regular cash dividend program since 2011.  We anticipate paying quarterly dividends for 2014 
pursuant to such program.  However, any future payment of dividends, including the timing and amount of any such dividends, 
will be at the discretion of our Board of Directors and will depend upon our earnings, liquidity, financial condition and such other 
factors as our Board of Directors considers relevant.  A change in our dividend policy could have an adverse effect on the market 
price of our common stock.

23

Mr. Pedersen, our Chairman and Chief Executive Officer, effectively controls our Company, and his interests may not be 
aligned with those of other stockholders. 

As of December 31, 2013, Mr. Pedersen owned approximately 36% of our total outstanding shares of common stock.  Holders 
of our Class B common stock are entitled to ten votes per share, while holders of our Class A common stock are entitled to only 
one vote per share.  Mr. Pedersen beneficially owned 13,192,845 shares of Class B common stock as of December 31, 2013, thus 
he controlled approximately 85% of the combined voting power of our stock as of December 31, 2013.  Accordingly, Mr. Pedersen 
controls the vote on all matters submitted to a vote of our stockholders.  As long as Mr. Pedersen beneficially owns a majority of 
the combined voting power of our common stock, he will have the ability, without the consent of our public stockholders, to elect 
all members of our Board of Directors and to control our management and affairs. 

Mr. Pedersen's voting control may have the effect of preventing or discouraging transactions involving an actual or a potential 
change of control of the Company, regardless of whether a premium is offered over then-current market prices. Mr. Pedersen will 
be able to cause a change of control of the Company.  Mr. Pedersen's voting control could adversely affect the trading price of our 
common stock if investors perceive disadvantages in owning stock in a company with such concentrated ownership. 

Mr. Pedersen could also cause a registration statement to be filed and to become effective under the Securities Act of 1933, 
thereby permitting him to freely sell or transfer the shares of common stock that he owns, which could have an impact on the 
trading price of our stock. 

Provisions in our charter documents and Delaware law may inhibit potential acquisition bids that you and other stockholders 
may consider favorable, and the market price of our Class A common stock may be lower as a result. 

There are provisions in our certificate of incorporation and bylaws that make it more difficult for a third party to acquire, or 
attempt to acquire, control of our Company, even if a change of control were considered favorable by you and other stockholders.  
Among the provisions that could have an anti-takeover effect, are provisions relating to the following:

•  The high vote nature of our Class B common stock;

•  The ability of the Board of Directors to issue preferred stock;

•  The inability of stockholders to take action by written consent; and 

•  The advance notice requirements for director nominations or other proposals submitted by our stockholders.

Item 1B. 

Unresolved SEC Staff Comments 

We have not received any written comments from the SEC staff regarding our periodic or current reports under the Exchange 

Act that remain unresolved. 

Item 2. 

Properties 

We lease our facilities, including offices, warehouses and labs, and we do not own any facilities or real estate materially 
important to our operations.  Our facilities are leased in close proximity to our customers.  As of December 31, 2013, we leased 
23 facilities throughout the metropolitan Washington, D.C. area and 49 facilities in other parts of the United States, for approximately 
1,500,000 square feet.  We also have employees working at customer sites throughout the United States and in other countries.  
Our leases expire between 2014 and 2022. 

We believe our current facilities are adequate to meet our current needs.  We do not anticipate any significant difficulty in 

renewing our leases or finding alternative space to lease upon the expiration of our leases and to support our future growth. 

24

Item 3. 

Legal Proceedings 

We are subject to certain legal proceedings, government audits, investigations, claims and disputes that arise in the ordinary 
course of our business.  Like most large government defense contractors, our contract costs are audited and reviewed on a continual 
basis by an in-house staff of auditors from the DCAA.  In addition to these routine audits, we are 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 our performance and administration of our government contracts are compliant with contractual requirements and applicable 
federal statutes and regulations.  An audit or investigation may result in a finding that our performance, systems and administration 
is  compliant  or,  alternatively,  may  result  in  the  government  initiating  proceedings  against  us  or  our  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. 

Although we cannot predict the outcome of these and other legal proceedings, investigations, claims and disputes, based on 
the information now available to us, we do not believe the ultimate resolution of these matters, either individually or in the aggregate, 
will have a material adverse effect on our business, prospects, financial condition or operating results.

There is no established public market for our Class B common stock. 

As of February 19, 2014, there were 64 holders of record of our Class A common stock and 3 holders of record of our Class 
B common stock.  The number of holders of record of our Class A common stock is not representative of the number of beneficial 
holders because many of the shares are held by depositories, brokers or nominees. 

Dividend Policy 

During fiscal years 2013 and 2012, we declared and paid quarterly dividends, each in the amount of $0.21 per share, on all 
issued and outstanding shares of common stock.  For 2014, we anticipate paying quarterly dividends, each in the amount of $0.21 
per share.  While we expect to continue the regular cash dividend program, any future dividends declared will be at the discretion 
of our Board of Directors and will depend, among other factors, upon our results of operations, financial condition and cash 
requirements, as well as such other factors our Board or Directors deems relevant. 

Recent Sales of Unregistered Securities 

We did not issue or sell any securities in fiscal year 2013 that were not registered under the Securities Act of 1933.  The 

issuance of shares to the Employee Stock Ownership Plan did not constitute sales within the meaning of the Securities Act.

Equity Compensation Plan Information 

Information regarding our equity compensation plans and the securities authorized for issuance thereunder is incorporated 
by reference in Item 12 “Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters.” 

Purchase of Equity Securities

The Company did not purchase equity securities during the year ended December 31, 2013.

Performance Graph

The stock performance graph compares the cumulative total shareholder return of ManTech common stock to the Nasdaq 
Stock Market (U.S.) Index, Standard & Poor's MidCap 400 Index, Russell 2000 Index, North American Tech Services Index and 
our Peer Group Index.  The period measured is December 31, 2008 to December 31, 2013.  The graph assumes an investment of 
$100 in ManTech common stock and each of the indices with reinvestment of all dividends. 

The Peer Group Index consists of four companies: CACI International Inc.; Dynamics Research Corporation; NCI, Inc.; and 
Leidos, Inc.  SEC rules require that if an index is selected that is different from the index used in the immediately preceding fiscal 
year, the total return must be compared to both the newly selected index and the index used in the prior year.  In the past, we used 
a customized peer group index for this comparison.  However, many of companies included in the Peer Group Index over time 
are no longer publicly traded companies.  We believe the North American Tech Services Index is a more appropriate index to 
compare us with other companies in our industry.  After this year, the Peer Group Index will no longer be included in the Stock 
Performance Graph.

Management's Discussion and Analysis of Financial Condition and Results of Operations 

The following discussion of our financial condition and results of operations should be read together with the consolidated 
financial statements and the notes to those statements included in Item 8 “Financial Statements and Supplemental Data.”  This 
discussion contains forward-looking statements that involve risks and uncertainties.  For a description of these forward-looking 
statements, refer to Part I “Forward-Looking Statements.”  A description of factors that could cause actual results to differ materially 
from the results we anticipate include, but are not limited to, those discussed in Item 1A “Risk Factors,” as well as discussed 
elsewhere in this Annual Report.

Overview 

ManTech is a leading provider of innovative technologies and solutions for mission-critical national security programs for 
the intelligence community; the departments of Defense, State, Homeland Security, Energy and Justice, including the Federal 
Bureau of Investigation (FBI); the healthcare and space communities; and other U.S. federal government customers.  

We  derive  revenues  primarily  from  contracts  with  U.S.  government  agencies  that  are  focused  on  national  security  and 
consequently our operational results are affected by U.S. government spending levels in the areas of defense, intelligence and 
homeland security.  During 2013, our financial performance was adversely impacted by the same factors affecting government 
services providers generally; public and political pressure regarding government funding levels, combined with uncertainty about 
the appropriations process, caused delays in awards and spending.  The U.S. government did not complete its budget process 

28

before the end of its fiscal year on September 30, 2013 and did not provide for a continuing resolution, which resulted in a federal 
government shutdown lasting 16 days, further impacting certain of our programs.  Our customers now have approved budgets 
through September 30, 2014 and a solid framework for a year longer.  Although the delays in procurements and cautious spending 
in 2013 will continue to impact our business in the short term, we believe that the recent budget clarity will allow our customers 
to accelerate the procurement of services.  We are well positioned to meet our customers' needs and grow our business as we move 
through 2014 and beyond.

Revenues

Substantially all of our revenues are derived from services and solutions provided to the federal government or to prime 
contractors supporting the federal government, including services provided by our employees, our subcontractors and through 
solutions that include third-party hardware and software that we purchase and integrate as a part of our overall solutions.  These 
requirements may vary from period-to-period depending on specific contract and customer requirements.  The following table 
shows revenues from each type of customer as a percentage of total revenues for the periods presented.

Several  years  ago,  management  decided  to  pursue  a  prime  position  on  contracts  by  bidding  as  a  prime  and  through  the 
acquisition of companies holding a prime position on desired contract vehicles.  As a result, our prime contract revenues as a 
percentage of our total revenues have increased each year since 2008.  The following table shows our revenues as prime contractor 
and as subcontractor as a percentage of our total revenues for the following periods:

We provide our services and solutions under three types of contracts: cost-reimbursable; time-and-materials; and fixed-price.  

Cost-reimbursable  contracts-Under  cost-reimbursable  contracts,  we  are  reimbursed  for  costs  that  are  determined  to  be 
reasonable, allowable and allocable to the contract and paid a fee representing the profit margin negotiated between us and the 
contracting agency, which may be fixed or performance based.  Under cost-reimbursable contracts we recognize revenues and an 
estimate of applicable fees earned as costs are incurred.  We consider fixed fees under cost-reimbursable contracts to be earned 
in proportion to the allowable costs incurred in performance of the contract.  For performance based fees under cost-reimbursable 
contracts, we recognize the relevant portion of the expected fee to be awarded by the customer at the time such fee can be reasonably 
estimated, based on factors such as our prior award experience and communications with the customer regarding performance, or 
upon customer approval.    

Fixed-price contracts-Under fixed-price contracts, we perform specific tasks for a fixed price.  Fixed-price contracts may 
include either a product delivery or specific service performance over a defined period.  Revenues on fixed-price contracts that 
provide for the Company to render services throughout a period is recognized as earned according to contract terms as the service 
is provided on a proportionate performance basis.  For fixed-price contracts that provide for the delivery of a specific product with 
related customer acceptance provisions, revenues are recognized as those products are delivered and accepted.  

Time-and-materials  contracts-Under  time-and-materials  contracts,  we  are  reimbursed  for  labor  at  fixed  hourly  rates  and 
generally reimbursed separately for allowable materials, costs and expenses at cost.  We recognize revenues under time-and-

29

materials contracts by multiplying the number of direct labor hours expended by the contract billing rates and adding the effect 
of other billable direct costs.  

Our contract mix varies from year-to-year due to numerous factors, including our business strategies and federal government 
procurement objectives.  Over the last few years, our customers have increasingly procured our services using cost-reimbursable 
contracts.  The following table shows revenues from each of these types of contracts as a percentage of total revenues for the 
periods presented.

Under cost-reimbursable contracts, there is limited financial risk, because we are reimbursed for all allowable direct and 
indirect costs.  However, profit margins on this type of contract tend to be lower than on time-and-materials and fixed-price 
contracts, and as a result of the shift in our contract mix, our profits have been impacted.  

Cost of Services 

Cost of services primarily includes direct costs incurred to provide our services and solutions to customers.  The most significant 
portion of these costs are direct labor costs, including salaries and wages, plus associated fringe benefits of our employees directly 
serving customers, in addition to the related management, facilities and infrastructure costs.  Cost of services also includes other 
direct costs, such as the costs of subcontractors and outside consultants and third-party materials, including hardware or software 
that we purchase and provide to the customer as part of an integrated solution.  

Changes in the mix of services and equipment provided under our contracts can result in variability in our contract margins.  
Since we earn higher profits on our own labor services, we expect the ratio of cost of services as a percent of revenues to decline 
when our labor services mix increases relative to subcontracted labor or third-party materials.  Conversely, as subcontracted labor 
or third-party material purchases for customers increase relative to our own labor services, we expect the ratio of cost of services 
as a percent of revenues to increase.  

The proportion that costs of services bears to revenues varies in part based on our mix of revenues by contract type.  In general, 
cost-reimbursable contracts are the least profitable of our government contracts but offer the lowest risk of loss.  Under time-and-
materials contracts, to the extent that our actual labor costs are higher or lower than the billing rates under the contract, our profit 
under the contract may either be greater or less than we anticipated or we may suffer a loss under the contract.  In general, we 
realize a higher profit margin on work performed under time-material contracts than cost-reimbursable contracts.  Fixed-price 
contracts generally offer higher profit margins opportunities but involve great financial risk because we bear impact of cost overruns 
in return for the full benefit of any cost savings.

General and Administrative Expenses 

General and administrative expenses include the salaries and wages, plus associated fringe benefits of our employees not 
performing work directly for customers, and associated facilities costs.  Among the functions covered by these costs are corporate 
business  development,  bid  and  proposal,  contracts  administration,  finance  and  accounting,  legal,  corporate  governance  and 
executive and senior management.  In addition, we included stock-based compensation, as well as depreciation and amortization 
expense related to the general and administrative function.  Depreciation and amortization expenses include the depreciation of 
computers, furniture and other equipment, the amortization of third party software we use internally, leasehold improvements and 
intangible assets.  Intangible assets include customer relationships and contract backlogs acquired in business combinations, and 
are amortized over their estimated useful lives.

Interest Expense 

Interest expense is primarily related to interest expense incurred or accrued under our outstanding borrowings on our 7.25% 

senior secured notes and deferred financing charges.

Interest Income

Interest income is primarily from cash on hand and notes receivable.

The primary driver of our decrease in revenue relates to reduced demand for services supporting Overseas  Contingency 
Operations (OCO) as a result of the accelerated withdrawal of U.S. forces and reduction in military operations in Afghanistan.  
The reduction in our OCO related work in 2013 was primarily due to reduced demand on a sustainment contract for Mine-Resistant 
Ambush-Protected (MRAP) vehicles and reduced demand for field service support on C4ISR systems.  These reductions were 
partially offset by revenue provided from contracts in the intelligence area, including contracts for IT infrastructure modernization 
and from growth from healthcare IT programs.  We expect the continued withdrawal from Afghanistan to impact revenues from 
our contracts providing OCO support throughout 2014. 

Cost of services 

The decrease in cost of services was primarily due to reductions in revenue.  As a percentage of revenues, direct labor costs 
increased to 37.9% for the year ended December 31, 2013, as compared to 36.1% for the same period in 2012.  As a percentage 
of revenues, other direct costs, which include subcontractors and third party equipment and materials used in the performance of 
our contracts, was 48.5% for the year ended December 31, 2013, compared to 49.6% for the same period in 2012.  We expect cost 
of services as a percentage of revenues to remain the same or slightly increase in 2014.

31

 
General and administrative expenses 

The decrease in general and administrative expense was due to cost reduction initiatives, including reductions in indirect 
support staff and lower stock based compensation expense.  As a percentage of revenues, general and administrative expense was 
slightly  lower  for  the  year  ended  December 31,  2013  when  compared  to  the  same  period  in  2012.    We  expect  general  and 
administrative expenses as a percentage of revenues to remain relatively stable in 2014.

Goodwill impairment

During  the  fourth  quarter  of  2013,  multiple  events  and  circumstances  indicated  a  significant  reduction  in  the  operating 
performance outlook of one of our reporting units.  These events included being awarded fewer contracts than anticipated on 
several competitive opportunities, changing mission priorities of the U.S. government in relation to certain of our C4ISR contracts 
and  OCO-related  work  (primarily  on  maintenance  and  sustainment  of  MRAP  vehicles),  continued  delays  in  our  customers' 
procurement cycle due, in part, to the U.S. government shutdown, and continued margin pressure on some of our contracts.  The 
culmination of these events led us to conduct an interim impairment analysis on the impacted reporting unit.  As a result of this 
analysis, we recorded a non-cash impairment charge of $118.4 million for the period ending December 31, 2013.  For additional 
information,  see  "Critical Accounting  Estimates  and  Policies  - Accounting  for  Business  Combinations,  Goodwill  and  Other 
Intangible Assets" and Note 7 to our consolidated financial statements in Item 8. 

Provision for income taxes

Our effective tax rate is affected by recurring items, such as tax rates and the relative amount of income we earn in various 
taxing jurisdictions.  It is also affected by discrete items that may occur in any given year, but are not consistent from year to year.  
Our effective income tax rates were 208.0% and 38.7% for the years ended December 31, 2013 and 2012, respectively.  The 
increase in the effective tax rate is due to the non-deductible portion of the non-cash goodwill impairment charge.  We expect the 
effective tax rate to be more in line with our historical rates in 2014. 

Equity in losses of unconsolidated subsidiaries

We account for our investment in the Fluor-ManTech Logistics Solutions, LLC under the equity method of accounting.  We 

recorded $(0.9) million and $0 in equity method losses for the years ended December 31, 2013 and 2012, respectively.  

Net income (loss)

The decrease in net income (loss) was due to a non-cash goodwill impairment charge, a reduction in revenues and margin 
pressure due to a shift to cost-reimbursable contract awards as well as the competitive market place.  To see net income exclusive 
of the non-cash goodwill impairment charge, see "Non-GAAP Financial Measures" below.

The primary driver of our decrease in revenues relates to reductions on our C4ISR support contracts and contracts that have 
ended.  These reductions were partially offset by revenues provided from new contract awards in the intelligence area.  The 
reduction in C4ISR work is primarily due to reduced demand for field service support and delays in enhancements to existing ISR 
systems. 

Cost of services 

The decrease in cost of services was primarily due to the decrease in revenues.  As a percentage of revenues, direct labor costs 
increased to 36.1% for the year ended December 31, 2012, as compared to 34.2% for the same period in 2011 as a result of an 
increase  in  our  percentage  of  work  as  a  prime  contractor.   As  a  percentage  of  revenues,  other  direct  costs,  which  include 
subcontractors and third party equipment and materials used in the performance of our contracts, decreased from 51.3% for the 
year ended December 31, 2011 to 49.6% for the same period in 2012 due to a reduction in other direct costs on the C4ISR support 
contracts.  

General and administrative expenses 

The increase in general and administrative expense was primarily due our acquisitions and facility related costs from newly 

leased office space.  

Other income (expense), net

The decrease in other income (expense), net was due to the sale of our investment in NetWitness in April 2011, which resulted 

in a gain of $3.7 million for the year ended December 31, 2011.

33

Provision for income taxes

Our effective income tax rates were 38.7% and 38.1% for the years ended December 31, 2012 and 2011, respectively.  Our 
tax rate is affected by recurring items, such as tax rates and the relative amount of income we earn in jurisdictions, which we 
expect to be fairly consistent in the near term.  It is also affected by discrete items that may occur in any given year, but are not 
consistent from year to year.  The difference between our statutory U.S. federal income tax rate of 35.0% and our effective tax 
rate is state income taxes and non-deductible compensation.    

Net income 

The decrease was due to lower revenues, increased general and administrative expense and margin pressure on our contracts, 

both from the shift in contract type to cost-reimbursable and increased competitive market place.  

Non-GAAP Financial Measures

Item 10(e) of Regulation S-K and other provisions of the securities laws regulate the use of financial measures that are not 
prepared in accordance with generally accepted accounting principles in the United States (GAAP).  We are providing certain 
non-GAAP  financial  measures  in  this Annual  Report  on  Form  10-K  because  we  believe  these  non-GAAP  measures  provide 
important supplemental information to the GAAP financial measures contained in our consolidated financial statements.  We 
believe these non-GAAP measures, which exclude the impact of the non-cash goodwill impairment charge taken in the fourth 
quarter of  fiscal year 2013, provide useful information to our investors to better evaluate period-to-period comparisons of our 
operating results.  Similarly, management uses these non-GAAP measures to gain a better understanding of our comparative 
operating performance from period-to-period and as a basis for forecasting future periods.

For the years ended December 31, 2013, 2012 and 2011 our backlog was $3.9 billion, $6.5 billion and $4.7 billion, respectively, 
of which $1.1 billion, $1.8 billion and $1.3 billion, respectively, was funded backlog.  The decrease in our backlog is primarily 
due  to  reduced  demand  on  OCO  contracts  resulting  from  the  accelerated  withdrawal  from Afghanistan.    Backlog  represents 
estimates that we calculate on a consistent basis.  For additional information on how we compute backlog, see “Backlog” in Item 
1 “Business.”

Liquidity and Capital Resources 

Historically, our primary liquidity needs have been the financing of acquisitions, working capital, payment under our  cash 
dividend program and capital expenditures.  Our primary sources of liquidity are cash provided by operations and our revolving 
credit facility.  

On December 31, 2013, our cash and cash equivalents balance was $269.0 million.  There were no outstanding borrowings 
under our revolving credit facility at December 31, 2013. At December 31, 2013, we were contingently liable under letters of 
credit totaling $0.2 million, which reduces our ability to borrow under our revolving credit facility by that amount.  The maximum 
available borrowings under our revolving credit facility at December 31, 2013 was $499.8 million.  At December 31, 2013, we 
had $200.0 million outstanding of our 7.25% senior unsecured notes.  For additional information concerning our revolving credit 
facility and 7.25% senior unsecured notes, see Note 8 to our consolidated financial statements in Item 8.

Generally, cash provided by operating activities is adequate to fund our operations, including payments under our regular 
cash dividend program.  Due to fluctuations in our cash flows and level of operations, it may become necessary from time-to-time 
to increase borrowings under our revolving credit facility to meet cash demands.  

Cash Flows from Operating Activities 

Our operating cash flow is primarily affected by our ability to invoice and collect from our clients in a timely manner, our 
ability to manage our vendor payments and the overall profitability of our contracts.  We bill most of our customers monthly after 
services are rendered.  Our accounts receivable days sales outstanding (DSO) was 84 and 79 for the years ended December 31, 
2013 and 2012.   For the years ended December 31, 2013, 2012 and 2011, our net cash flows from operating activities were $188.3 
million, $126.3 million and $221.4 million, respectively.  The increase in net cash flows from operating activities during the year 
ended December 31, 2013 when compared to the same period in 2012 was primarily due to the collection of accounts receivable 
and the timing of payments to our vendors and employees.  The decrease in net cash flows from operating activities during the 
year ended December 31, 2012 compared to the same period in 2011 was primarily due to decreased billings in excess of revenue 
earned, lower net income, and the timing of payments under incentive compensation plans. 

Cash Flows from Investing Activities

Our cash flow from investing activities consists primarily of business combinations, purchases of property and equipment 
and investments in capitalized software for internal use.  For the year ended December 31, 2013, 2012 and 2011 our net cash 
outflows from investing activities were were $24.8 million, $76.0 million and $165.5 million, respectively.  For the year ended 
December 31, 2013, our net cash outflows from investing activities were primarily due to the acquisition of ALTA Systems, Inc. 
and capital expenditures.  For the year ended December 31, 2012, our net cash outflows from investing activities were due to the 
acquisition of HBGary, Inc. and Evolvent Technologies, Inc. and capital expenditures.  For the year ended December 31, 2011, 
our net cash outflows from investing activities were due to the purchase of property and equipment primarily related to a mobile 
telecommunication network built for use on one of our contracts in Afghanistan and the acquisition of WINS and TranTech. 

Cash Flows from Financing Activities 

For the years ended December 31, 2013, 2012 and 2011, our net cash outflows from financing activities were $29.4 million, 
$29.8 million and $26.2 million, respectively.  For the years ended December 31, 2013, 2012 and 2011, our net cash outflows 
from financing activities resulted primarily from dividends paid.

Revolving Credit Facility 

We maintain a credit agreement with a syndicate of lenders led by Bank of America, N.A., as administrative agent.  The credit 
agreement provides for a $500.0 million revolving credit facility, with a $25.0 million letter of credit sublimit and a $30.0 million 
swing line loan sublimit.  The credit agreement also contains an accordion feature that permits the Company to arrange with the 
lenders for the provision of up to $250.0 million in additional commitments.  The maturity date for this agreement is October 12, 
2016.  

Borrowings under our credit agreement are collateralized by substantially all the assets of ManTech and its Material Subsidiaries 
(as defined in the credit agreement) and bear interest at one of the following variable rates as selected by the Company at the time 
of  borrowing:  a  London  Interbank  Offer  Rate  (LIBOR)  based  rate  plus  market-rate  spreads  (1.25%  to  2.25%  based  on  our 
consolidated total leverage ratio) or Bank of America's base rate plus market spreads (0.25% to 1.25% based on our consolidated 
total leverage ratio).  

35

The terms of the credit agreement permit prepayment and termination of the loan commitments at any time, subject to certain 
conditions.  The credit agreement requires the Company to comply with specified financial covenants, including the maintenance 
of a certain leverage ratios and a certain fixed charge coverage ratio.  The credit agreement also contains various covenants, 
including affirmative covenants with respect to certain reporting requirements and maintaining certain business activities, and 
negative  covenants  that,  among  other  things,  may  limit  or  impose  restrictions  on  our  ability  to  incur  liens,  incur  additional 
indebtedness, make investments, make acquisitions and undertake certain additional actions.  As of, and during, December 31, 
2013 and 2012, we were in compliance with our financial covenants under the credit agreement.  

There was no outstanding balance on our revolving credit facility at December 31, 2013 and 2012.  

7.25% Senior Unsecured Notes

We have $200.0 million in aggregate principal amount of 7.25% senior unsecured notes that are registered under the Securities 
Act of 1933, as amended.  The 7.25% senior unsecured notes were issued April 13, 2010 and mature on April 15, 2018.  We have 
determined that we will redeem these notes in April 2014 in accordance with their terms.  The aggregate amount necessary to 
redeem the notes in accordance with the optional redemption provision of the notes is $207,250,000.  We expect to fund the 
redemption of the notes with cash from operations and the use of our revolving credit facility.  

The  indenture  governing  the  7.25%  senior  unsecured  notes  contains  customary  events  of  default,  as  well  as  restrictive 
covenants, which, subject to important exceptions and qualifications specified in such indenture, will, among other things, limit 
our ability and the ability of our subsidiaries that guarantee the 7.25% senior unsecured notes to: pay dividends or distributions, 
repurchase equity, prepay subordinated debt or make certain investments; incur additional debt or issue certain disqualified stock 
and preferred stock; incur liens on assets; merge or consolidate with another company or sell all or substantially all assets; and 
allow to exist certain control provisions.  As of December 31, 2013 and 2012, the Company was in compliance with all covenants 
required by the indenture.

Capital Resources

We believe the capital resources available to us from cash on hand of $269.0 million at December 31, 2013, our $500.0 million 
capacity under our revolving credit facility and cash from our operations are adequate to fund our anticipated cash requirements 
for at least the next year, including payments under our regular cash dividend program.  We anticipate financing our external 
growth from acquisitions and our longer-term internal growth through one or more of the following sources: cash from operations; 
use of our revolving credit facility; and additional borrowing or issuance of debt or equity.  

Short-Term Borrowings

From time to time, we borrow funds against our revolving credit facility for working capital requirements and funding of 
operations, as well as acquisitions.  Borrowings under our revolving credit facility bear interest at one of the following variable 
rates as selected by the Company at the time of the borrowing: a LIBOR based rate plus market spreads (1.25% to 2.25% based 
on our consolidated total leverage ratio) or the Bank of America's base rate plus market spreads (0.25% to 1.25% based on our 
consolidated total leverage ratio).  In the next year we may use, as needed, our revolving credit facility or additional sources of 
borrowings in order to fund our anticipated cash requirements. 

The following table summarizes the activity under our revolving credit facility for the years ended December 31, 2013, 2012 

and 2011 (in thousands):

Cash Management

To the extent possible, we invest our available cash in short-term, investment grade securities in accordance with our investment 
policy. Under our investment policy, we manage our investments in accordance with the priorities of maintaining the safety of our 
principal, maintaining the liquidity of our investments, maximizing the yield on our investments and investing our cash to the 
fullest extent possible. Our investment policy provides that no investment security can have a final maturity that exceeds six 
months and that the weighted average maturity of the portfolio cannot exceed 60 days.  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.

Dividend

During the years ended December 31, 2013 and 2012, we declared and paid quarterly dividends in the amount of $0.21 per 
share on both classes of common stock.  While we expect to continue the regular cash dividend program, any future dividends 
declared will be at the discretion of our Board of Directors and will depend, among other factors, upon our results of operations, 
financial condition and cash requirements, as well as such other factors our Board or Directors deems relevant. 

Off-Balance Sheet Arrangements 

None. 

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 our financial condition and results of operations.  The discussion and analysis of our financial condition 
and  results  of  operations  are  based  on  our  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.  Our significant accounting policies, 
including the critical policies listed below, are more fully described in the notes to our consolidated financial statements included 
in this report. 

Revenue Recognition and Cost Estimation 

We recognize revenues when persuasive evidence of an arrangement exists, services have been rendered, the contract price 
is fixed or determinable and collectability is reasonably assured.  We have a standard internal process that we use to determine 
whether all required criteria for revenue recognition have been met. 

Our revenues consist primarily of services provided by our employees and the pass through of costs for materials and subcontract 
efforts under contracts with our 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. 

We derive the majority of our revenues from cost-plus-fixed-fee, cost-plus-award-fee, firm-fixed-price or time-and-materials 
contracts.  Revenues for cost-reimbursable contracts are recorded as reimbursable costs are incurred, including an estimated share 
of the applicable contractual fees earned.  For performance-based fees under cost-reimbursable contracts, we recognize the relevant 
portion of the expected fee to be awarded by the customer at the time such fee can be reasonably estimated, based on factors such 
as our prior award experience and communications with the customer regarding performance, or upon approval by the customer.  
For time-and-materials contracts, revenues are recognized to the extent of billable rates times hours delivered plus materials and 
other reimbursable costs incurred.  For long-term fixed-price production contracts, revenues are recognized at a rate per unit as 
the units are delivered or by other methods to measure services provided.  Revenues from other long-term fixed-price contracts 
are recognized ratably over the contract period or by other appropriate methods to measure services provided.  Contract costs are 
expensed as incurred except for certain limited long-term contracts noted below.  For long-term contracts, specifically described 
in the scope section of ASC 605-35, we apply the percentage of completion method.  Under the percentage of completion method, 
income is recognized at a consistent profit margin over the period of performance based on estimated profit margins at completion 
of the contract.  This method of accounting requires estimating the total revenues and total contract cost at completion of the 
contract.  During the performance of long-term contracts, these estimates are periodically reviewed and revisions are made as 
required using the cumulative catch-up method of accounting.  The impact on revenues and contract profit as a result of these 
revisions is included in the periods in which the revisions are made. This method can result in the deferral of costs or the deferral 
37

of profit on these contracts.  Because we assume the risk of performing a fixed-price contract at a set price, the failure to accurately 
estimate ultimate costs or to control costs during performance of the work could result, and in some instances has resulted, in 
reduced profits or losses for such contracts.  Both the individual changes in contract estimates and aggregate net changes in contract 
estimates recognized using the cumulative catch-up method of accounting were not material to the consolidated statement of 
operations for all periods presented.  Estimated losses on contracts at completion are recognized when identified.  In certain 
circumstances, revenues are recognized when contract amendments have not been finalized. 

Accounting for Business Combinations, Goodwill and Other Intangible Assets

The purchase price of an acquired business is allocated to the tangible assets, financial assets and separately recognized 
intangible assets acquired less liabilities assumed based upon their respective fair values, with the excess recorded as goodwill.  
Such fair value assessments require judgments and estimates that can be affected by contract performance and other factors over 
time, which may cause final amounts to differ materially from original estimates.

We review goodwill at least annually for impairment, or whenever events or circumstances indicate that the carrying value 
of long-lived assets may not be fully recoverable.  We perform this review at the reporting unit level, which is one level below 
our one reportable segment.  The goodwill impairment test is a two-step process performed at the reporting unit level.  The first 
step of the goodwill impairment test compares the fair value of a reporting unit with its carrying amount (including goodwill).  If 
the reporting unit's fair value exceeds its carrying value, no further procedures are required.  However, if the reporting unit's fair 
value is less than its carrying value, an impairment of goodwill may exist, requiring a second step to be performed.  Step two of 
this test measures the amount of the impairment loss, if any.  Step two of this test requires the allocation of the reporting unit's fair 
value to its assets and liabilities, including any unrecognized intangible assets, in a hypothetical analysis that calculates the implied 
fair value of goodwill as if the reporting unit were being acquired in a business combination.  If the implied fair value of goodwill 
is less than the carrying value, the difference is recorded as a goodwill impairment charge in operations.  

The fair values of the reporting units are determined based on a weighting of the income approach, market approach and 
market transaction approach.  The income approach is a valuation technique in which fair value is based from forecasted future 
cash flow discounted at the appropriate rate of return commensurate with the risk as well as current rates of return for equity and 
debt capital as of the valuation date.  The forecast used in our estimation of fair value was developed by management based on a 
contract basis, incorporating adjustments to reflect known contract and market considerations (such as reductions and uncertainty 
in government spending, pricing pressure and opportunities).  The discount rate utilizes a risk adjusted weighted average cost of 
capital.  The market approach is a valuation technique in which the fair value is calculated based on market prices realized in an 
actual arm's length transaction.  The technique consists of undertaking a detailed market analysis of publicly traded companies 
that provides a reasonable basis for comparison to the company.  Valuation ratios, which relate market prices to selected financial 
statistics derived from comparable companies, are selected and applied to the company after consideration of adjustments for 
financial position, growth, market, profitability and other factors.  The market transaction approach is a valuation technique in 
which the fair value is calculated based on market prices realized in actual arm's length transactions.  The technique consists of 
undertaking a detailed market analysis of merged and acquired companies that provided a reasonable basis for comparison to the 
company.  Valuation ratios, which relate market prices to selected financial statistics derived from comparable companies, are 
selected and applied to the company after consideration of adjustments for financial position, growth, market, profitability and 
other factors.  To assess the reasonableness of the calculated reporting unit fair values, we compare the sum of the reporting units' 
fair values to the Company's market capitalization (per share stock price times the number of shares outstanding) and calculate an 
implied control premium (the excess of the sum of the reporting units' fair values over the market capitalization), and then assess 
the reasonableness of our implied control premium.

We have elected to perform our annual review during the second quarter of each calendar year.  In addition, management 
monitors events and circumstances that could result in an impairment.  A significant amount of judgment is involved in determining 
if an indicator of impairment has occurred between annual testing dates.  Events that could cause the fair value of our long-lived 
assets to decrease include; changes in our business environment or market conditions, a material change in our financial outlook, 
including declines in expected revenue growth rates and operating margins, or a material decline in the market price for our stock.  
If any impairment were indicated as a result of a review, we would recognize a loss based on the amount by which the carrying 
amount exceeds the estimated fair value.

  During  the  fourth  quarter  of  2013,  multiple  events  and  circumstances  indicated  a  significant  reduction  in  the  operating 
performance outlook of one of our reporting units.  These events include lower than expected contract awards on several competitive 
opportunities,  changing  mission  priorities  of  the  U.S.  government  in  relation  to  our  C4ISR  contracts  and  OCO-related  work 
(primarily on maintenance and sustainment of MRAP vehicles), continued delays in our customers' procurement cycle due, in 
part, to the U.S. government shutdown, and continued margin pressures on some of our contracts.  The culmination of these events 

38

 
led us to conduct an interim goodwill impairment analysis on the impacted reporting unit.  As a result of this analysis, we recorded 
a non-cash goodwill impairment charge of $118.4 million for the period ending December 31, 2013.  

Due to the many variables inherent in the estimation of a reporting unit's fair value and the relative size of our recorded 

goodwill, differences in assumptions may have a material effect on the results of our goodwill impairment analysis.

Accounting Standards Updates

In July 2013, Accounting Standard Update No. 2013-11, Income Taxes (Topic 740), was issued.  This Update applies to all 
entities that have unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward 
exists at the reporting date.  In accordance with this Update, an unrecognized tax benefit, or a portion of an unrecognized tax 
benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, 
a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax 
loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any 
additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does 
not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax 
benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The 
assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist 
at the reporting date and should be made presuming disallowance of the tax position at the reporting date. For example, an entity 
should not evaluate whether the deferred tax asset expires before the statute of limitations on the tax position or whether the 
deferred tax asset may be used prior to the unrecognized tax benefit being settled.  The amendments in this Update do not require 
new recurring disclosures.  The amendments in this Update are effective for fiscal years, and interim periods within those years, 
beginning  after  December  15,  2013.  Early  adoption  is  permitted.    The  amendments  should  be  applied  prospectively  to  all 
unrecognized tax benefits that exist at the effective date. Retrospective application is permitted.  The adoption of Accounting 
Standard Update No. 2013-11 is not expected to have a material impact on our results of operations, financial position or cash 
flows.

In February 2013, Accounting Standard Update No. 2013-2, Other Comprehensive Income (Topic 220), was issued.  The 
amendments in this Update apply to all entities that issue financial statements that are presented in conformity with U.S. GAAP 
and that report items of other comprehensive income. Public companies are required to comply with these amendments for all 
reporting periods presented, including interim periods.  The amendments do not change the current requirements for reporting net 
income or other comprehensive income in financial statements. However, the amendments require an entity to provide information 
about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required 
to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out 
of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is 
required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are 
not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other 
disclosures required under U.S. GAAP that provide additional detail about those amounts.  For public entities, the amendments 
are effective prospectively for reporting periods beginning after December 15, 2012.  The adoption of Accounting Standard Update 
No. 2013-2 did not have an impact on our results of operations, financial position or cash flows.

pension plans for certain retired employees of an acquired company, which is included in the accrued retirement amount on our 
consolidated balance sheets.  Excludes liabilities related to one non-qualified deferred compensation plan for certain highly 
compensated employees, which are included in the accrued retirement amount on our consolidated balance sheets.  The funds 
deferred by the employees are invested and maintained in rabbi trusts, which are reflected in the employee supplemental savings 
plan assets on our consolidated balance sheets.  These liabilities will be satisfied by assets held in rabbi trusts.  See Note 11 to 
our consolidated financial statements in Item 8 for additional information regarding retirement plans.

Item 7A.  Quantitative and Qualitative Disclosures about Market Risk 

Our  exposure  to  market  risk  relates  to  changes  in  interest  rates  for  borrowings  under  our  revolving  credit  facility.   At 
December 31, 2013, we had no outstanding balance on our revolving credit facility.  Borrowings under our revolving credit facility 
bear interest at variable rates.  A hypothetical 10% increase in interest rates would have no effect on our annual interest expense 
for the year ended December 31, 2013.

We do not use derivative financial instruments for speculative or trading purposes.  When we have excess cash, we invest in 
short-term, investment grade, interest-bearing securities.  Our investments are made in accordance with an investment policy.  
Under this policy, no investment security can have a maturity exceeding six months and the weighted average maturity of the 
portfolio cannot exceed 60 days.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

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

We  have  audited  the  accompanying  consolidated  balance  sheets  of  ManTech  International  Corporation  and  subsidiaries  (the 
"Company") as of December 31, 2013 and 2012, and the related consolidated statements of income and loss, comprehensive 
income and loss, changes in stockholders' equity, and cash flows for each of the three years in the period ended December 31, 
2013.  Our audits also included the financial statement schedule listed in the Index at Item 15.  These financial statements and 
financial statement schedule are the responsibility of the Company's management.  Our responsibility is to express an opinion on 
the financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).  
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 as of December 31, 2013 and 2012, and the results of their operations and their cash 
flows for each of the three years in the period ended December 31, 2013, in conformity with accounting principles generally 
accepted in the United States of America.  Also, 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.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 
Company's internal control over financial reporting as of December 31, 2013, based on the criteria established in Internal Control-
Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report 
dated February 21, 2014 expressed an unqualified opinion on the Company's internal control over financial reporting.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

Years Ended December 31, 2013, 2012 and 2011 

1.  Description of the Business 

ManTech International Corporation (depending on the circumstances, “ManTech” “Company” “we” “our” “ours” or “us”) is 
a leading provider of innovative technologies and solutions for mission-critical national security programs for the intelligence 
community;  the  departments  of  Defense,  State,  Homeland  Security,  Energy  and  Justice,  including  the  Federal  Bureau  of 
Investigation (FBI); the healthcare and space communities; and other U.S. federal government customers.  We provide support to 
critical national security programs for approximately 50 federal agencies through over 1,000 current contracts.  Our services 
include  the  following  solution  sets  that  are  aligned  with  the  long-term  needs  of  our  customers:  cyber  security;  information 
technology  (IT)  modernization  and  sustainment;  intelligence/counterintelligence  solutions  and  support;  systems  engineering;  
healthcare analytics and IT; test and evaluation; command, control, communications, computers, intelligence, surveillance and 
reconnaissance  (C4ISR)  solutions  and  services;  environmental,  range  and  sustainability  services;  testing  services;  and  global 
logistics support.  We support major national missions, such as military readiness and wellness, terrorist threat detection, information 
security and border protection.  Our employees operate primarily in the United States, as well as numerous locations internationally.

2.  Summary of Significant Accounting Policies 

Principles of Consolidation-Our consolidated financial statements include the accounts of ManTech International Corporation, 
subsidiaries we control and variable interest entities that are required to be consolidated.  All intercompany accounts and transactions 
have been eliminated.  Investments in entities where we have significant influence, but not control, are accounted for using the 
equity method.  

Use of Accounting Estimates-We prepare our consolidated financial statements in conformity with accounting principles 
generally accepted in the United States of America, which require management to make estimates and assumptions that affect the 
reported amounts of assets and liabilities, 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-We derive the majority of our revenues from cost-plus-fixed-fee, cost-plus-award-fee, firm-fixed-price 
or  time-and-materials  contracts.    Revenues  for  cost-reimbursable  contracts  are  recorded  as  reimbursable  costs  are  incurred, 
including  an  estimated  share  of  the  applicable  contractual  fees  earned.    For  performance-based  fees  under  cost-reimbursable 
contracts, we recognize the relevant portion of the expected fee to be awarded by the customer at the time such fee can be reasonably 
estimated, based on factors such as our prior award experience and communications with the customer regarding performance, or 
upon approval by the customer.  For time-and-materials contracts, revenues are recognized to the extent of billable rates times 
hours delivered plus materials and other reimbursable costs incurred.  For long-term fixed-price production contracts, revenues 
are recognized at a rate per unit as the units are delivered or by other methods to measure services provided.  Revenues from other 
long-term fixed-price contracts are recognized ratably over the contract period or by other appropriate methods to measure services 
provided.  Contract costs are expensed as incurred except for certain limited long-term contracts noted below.  For long-term 
contracts, specifically described in the scope section of ASC 605-35, we apply the percentage of completion method.  Under the 
percentage of completion method, income is recognized at a consistent profit margin over the period of performance based on 
estimated profit margins at completion of the contract.  This method of accounting requires estimating the total revenues and total 
contract  cost  at  completion  of  the  contract.    During  the  performance  of  long-term  contracts,  these  estimates  are  periodically 
reviewed and revisions are made as required using the cumulative catch-up method of accounting.  The impact on revenues and 
contract profit as a result of these revisions is included in the periods in which the revisions are made. This method can result in 
the deferral of costs or the deferral of profit on these contracts.  Because we assume the risk of performing a fixed-price contract 
at a set price, the failure to accurately estimate ultimate costs or to control costs during performance of the work could result, and 
in some instances has resulted, in reduced profits or losses for such contracts.  Both the individual changes in contract estimates 
and aggregate net changes in contract estimates recognized using the cumulative catch-up method of accounting were not material 
to the consolidated statement of operations for all periods presented.  Estimated losses on contracts at completion are recognized 
when identified.  In certain circumstances, revenues are recognized when contract amendments have not been finalized.

Cost of Services-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. 

48

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.  Due to the short 
maturity of cash equivalents, the carrying value on our consolidated balance sheets approximates fair value. 

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 Method-Furniture and office equipment are depreciated using the straight-line method with 
estimated useful lives ranging from one to seven years.  Leasehold improvements are amortized using the straight-line method 
over the term of the lease. 

Contractual Inventory-Inventory consists of finished goods purchased for a specific contract.  

Goodwill-Goodwill represents the excess of cost over the fair value of net tangible and identifiable intangible assets of acquired 

companies.   

Other Intangible Assets-Contract rights and other intangible assets are amortized primarily using the pattern of benefits 

method over periods ranging from one to twenty-five years.  

We accounted for the cost of computer software developed or obtained for internal use in accordance with ASC 350-985, 

Software.  These capitalized software costs are included in other intangible assets, net. 

We account for software development costs related to software products for sale, lease or otherwise marketed in accordance 
with ASC 985-20, Costs of Software to be Sold, Leased, or Marketed.  For projects fully funded by us, 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 based on units sold or on 
a straight-line basis over a five-year period or other such shorter period as may be required.  

Impairment of Long-Lived Assets-Whenever events or changes in circumstances indicate that the carrying amount of long-
lived assets may not be fully recoverable, we evaluate 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, we would 
recognize a loss based on the amount by which the carrying amount exceeds the estimated fair value. 

We review goodwill at least annually for impairment, or whenever events or circumstances indicate that the carrying value 
of long-lived assets may not be fully recoverable.  We have elected to perform our annual review during the second quarter of 
each calendar year.  If any impairment was indicated as a result of a review, we would recognize a loss based on the amount by 
which the carrying amount exceeds the estimated fair value.  As a result of interim analysis conducted in the fourth quarter of 
2013, we recorded a non-cash goodwill impairment charge of $118.4 million for the period ending December 31, 2013.  Furthermore, 
other intangible assets were tested for impairment in conjunction with the interim analysis and no impairment loss was identified. 

Employee  Supplemental  Savings  Plan  Assets-We  maintain  several  non-qualified  defined  contribution  supplemental 
retirement plans for certain key employees that are accounted for in accordance with ASC 710-10-05, Deferred Compensation - 
Rabbi Trusts, 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.  The assets held by the rabbi trusts are recorded 
at cash surrender value in our consolidated financial statements as Employee Supplemental Savings Plan assets with a related 
liability to employees recorded as a deferred compensation liability in accrued retirement. 

Billings In Excess of Revenue Earned-We receive advances and milestone payments from customers that exceed the revenues 

earned to date.  We classify such items as current liabilities. 

Stock-based Compensation-We account for stock-based compensation in accordance with ASC 718, Compensation - Stock 
Compensation.  ASC 718 requires the use of a valuation model to calculate the fair value of stock-based awards.  We have elected 
to use the Black-Scholes-Merton pricing model to determine fair value on the dates of grant.  The fair value is included in operating 
expenses or capitalized, as appropriate, straight-line over the period in which service is provided in exchange for the award.   

Income Taxes-We account for income taxes in accordance with ASC 740, Income Taxes.  Under this method, deferred income 
taxes are determined based on the estimated future tax effects of differences between the financial statement and tax bases of assets 
49

and liabilities given the provisions of enacted tax laws.  Deferred income tax provisions and benefits are based on changes to the 
assets or liabilities from year-to-year.  In providing for deferred taxes, we consider tax regulations of the jurisdictions in which 
we operate, estimates of future taxable income and available tax planning strategies.  If tax regulations, operating results or the 
ability to implement tax-planning strategies vary, adjustments to the carrying value of deferred tax assets and liabilities may be 
required.  Valuation allowances are recorded related to deferred tax assets based on the “more likely than not” criteria.  We recognize 
the financial statement benefit of a tax position only after determining that the relevant tax authority would “more likely than not” 
sustain the position following an audit.  For tax positions meeting the “more likely than not” threshold, the amount recognized in 
the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement 
with the relevant tax authority. 

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 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)  is  presented  in  our  consolidated  statements  of  changes  in 
stockholders' equity.  Comprehensive income (loss) consists of net income (loss); translation adjustments, net of tax; and actuarial 
gain (loss) on defined benefit pension plan, net of tax.

Fair Value of Financial Instruments-The carrying value of our cash and cash equivalents, accounts receivable, accounts 

payable and accrued expenses approximate their fair value because of the short-term nature of these amounts. 

Variable Interest Entities-We determine whether we have a controlling financial interest in a Variable Interest Entity (VIE).  
The reporting entity with a variable interest or interest that provides the reporting entity with a controlling financial interest in a 
VIE will have both (a) the power to direct the activities of a VIE that most significantly impact the VIE's economic performance 
and (b) the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits 
from the VIE that could potentially be significant to the VIE.  We have one entity that has been consolidated as a VIE.  The purpose 
of the entity is to perform on certain U.S. Navy contracts.  The maximum amount of loss we are exposed to as of December 31, 
2013 was not material to our consolidated financial statements.

Equity Method Investments-Investments where we have the ability to exercise significant influence, but we do not control, 
are accounted for under the equity method of accounting and are included in other assets on our consolidated balance sheets.  
Significant influence typically exists if we have a 20%  to 50%  ownership interest in the investee.  Under this method of accounting, 
our share of the net earnings or losses of the investee is included in equity in losses of unconsolidated subsidiaries on our consolidated 
statement of income and loss.

Accounting Standards Updates 

In July 2013, Accounting Standard Update No. 2013-11, Income Taxes (Topic 740), was issued.  This Update applies to all 
entities that have unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward 
exists at the reporting date.  In accordance with this Update, an unrecognized tax benefit, or a portion of an unrecognized tax 
benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, 
a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax 
loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any 
additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does 
not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax 
benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The 
assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist 
at the reporting date and should be made presuming disallowance of the tax position at the reporting date. For example, an entity 
should not evaluate whether the deferred tax asset expires before the statute of limitations on the tax position or whether the 
deferred tax asset may be used prior to the unrecognized tax benefit being settled.  The amendments in this Update do not require 
new recurring disclosures.  The amendments in this Update are effective for fiscal years, and interim periods within those years, 
beginning  after  December  15,  2013.  Early  adoption  is  permitted.    The  amendments  should  be  applied  prospectively  to  all 
unrecognized tax benefits that exist at the effective date. Retrospective application is permitted.  The adoption of Accounting 
Standard Update No. 2013-11 is not expected to have an impact on our results of operations, financial position or cash flows.

In February 2013, Accounting Standard Update No. 2013-2, Other Comprehensive Income (Topic 220), was issued.  The 
amendments in this Update apply to all entities that issue financial statements that are presented in conformity with U.S. GAAP 
and that report items of other comprehensive income. Public companies are required to comply with these amendments for all 
reporting periods presented, including interim periods.  The amendments do not change the current requirements for reporting net 
50

income or other comprehensive income in financial statements. However, the amendments require an entity to provide information 
about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required 
to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out 
of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is 
required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are 
not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other 
disclosures required under U.S. GAAP that provide additional detail about those amounts.  For public entities, the amendments 
are effective prospectively for reporting periods beginning after December 15, 2012.  The adoption of Accounting Standard Update 
No. 2013-2 did not have an impact on our results of operations, financial position or cash flows.

3.  Acquisitions

ALTA Systems, Inc.-On January 8, 2013, we completed the acquisition of ALTA Systems, Inc. (ALTA). The result of ALTA's 
operations have been included in our consolidated financial statements since that date.  The acquisition was completed through a 
stock purchase agreement dated January 8, 2013, by and among ManTech International Corporation, ALTA Holdings LLC and 
the sole member of ALTA Holding LLC.  ALTA is an information technology (IT) and professional services company with valuable 
applications in healthcare systems and capital planning.  ALTA provides a broad range of IT and professional services to government 
and private industry in three major areas: capital planning and investment control; system design, development and operations; 
and fraud detection and statistical analysis. The acquisition allows ManTech to deliver technology services through ALTA's prime 
position on the Centers of Medicare and Medicaid Services (CMS) Enterprise Systems Development (ESD) contract.  ManTech 
funded the acquisition with cash on hand.  The stock purchase agreement did not contain provisions for contingent consideration.

Revenues were $6.2 million and net income was $0.1 million for the period from January 8, 2013 to December 31, 2013.  For 
the  year  ended  December 31,  2013,  ManTech  incurred  approximately  $0.1  million  of  acquisition  costs  related  to  the ALTA 
transaction, which are included in the general and administrative expense in our consolidated statement of income and loss.

The purchase price of $10.2 million was allocated to the underlying assets and liabilities based on their estimated fair value 
at the date of acquisition.  We have recorded total assets of $11.1 million, including goodwill and intangible assets recognized in 
connection with the acquisition, and total liabilities of $0.9 million.  Included in total assets were $0.7 million in acquisition related 
intangible assets.  We recorded goodwill of $9.1 million, which will be deductible for tax purposes over 15 years, assuming adequate 
levels of taxable income.  Recognition of goodwill is largely attributed to the value paid for ALTA's capabilities in providing 
technology services to the federal government in the health care sector.  

In allocating the purchase price, we considered among other factors, analysis of historical financial performance and estimates 
of future performance of ALTA's contracts.  The components of other intangible assets associated with the acquisition were customer 
relationships and backlog valued at $0.6 million and $0.1 million, respectively.  Customer contracts and related relationships 
represent the underlying relationships and agreements with ALTA's existing customers.  Customer relationships and backlog are 
amortized straight-line over their estimated useful lives of approximately 20 years and 1 year, respectively.  The weighted-average 
amortization period for the intangible assets is 17.1 years.   

HBGary, Inc.-On April 2, 2012, we completed the acquisition of certain assets of HBGary, Inc. (HBGary).  The results of 
HBGary's operations have been included in our consolidated financial statements since that date.  The acquisition was completed 
through an asset purchase agreement dated February 27, 2012, by and among a subsidiary of ManTech International Corporation, 
HBGary and the shareholders of HBGary.  HBGary provides a comprehensive suite of software products to detect, analyze and 
diagnose Advance Persistent Threats and targeted malware.  The company has customers in the financial services, energy, critical 
infrastructure and technology sectors.  This acquisition broadened our cyber security solution capability for customers.  ManTech 
funded the acquisition with cash on hand.  The asset purchase agreement did not contain provisions for contingent consideration.

Revenues were $3.2 million and net loss of $(3.2) million for the period from April 2, 2012 to December 31, 2012.  For the 
year  ended  December 31,  2012,  ManTech  incurred  approximately  $0.8  million  of  acquisition  costs  related  to  the  HBGary 
transaction, which are included in the general and administrative expense in our consolidated statement of income and loss. 

The purchase price of $23.8 million was allocated to the underlying assets and liabilities based on their fair value at the date 
of  acquisition.    Total  assets  were  $24.6  million,  including  goodwill  and  intangible  assets  recognized  in  connection  with  the 
acquisition, and total liabilities were $0.8 million.  Included in total assets were $3.1 million in acquisition related intangibles 
assets.  We recorded goodwill of $20.1 million, which will be deductible for tax purposes over 15 years, assuming adequate levels 
of taxable income.  Recognition of goodwill is largely attributed to the value paid for HBGary's capabilities in providing cyber 
service and product solutions to both federal and commercial customers.

51

The components of other intangible assets associated with the acquisition were developed technology, customer relationships 
and trademark valued at $2.0 million, $0.9 million and $0.2 million, respectively.  Developed technology represents the software 
developed by HBGary to detect, analyze and diagnose Advanced Persistent Threats and targeted malware.  Customer relationship 
represent the underlying relationship with HBGary customers in the financial services, energy, critical infrastructure and technology 
sectors.    Trademark  represents  the  HBGary  trade  name  that  is  recognized  in  the  industry.    Developed  technology,  customer 
relationships and trademark are amortized straight-line over their estimate useful lives of approximately 3 years, 2 years and 2 
years, respectively.  The weighted-average amortization period for the intangible assets is 2.5 years.

Evolvent Technologies, Inc.-On January 6, 2012, we completed the acquisition of Evolvent Technologies, Inc. (Evolvent).  
The results of Evolvent's operations have been included in our consolidated financial statements since that date.  The acquisition 
was  completed  through  an  equity  purchase  agreement  dated  January 6,  2012,  by  and  among  ManTech,  shareholders  and 
warrantholders of the parent of Evolvent, Evolvent and Prudent Management, LLC in its capacity as the sellers' representative.  
Evolvent provides services in clinical IT, clinical business intelligence, imaging cyber security, behavioral health, tele-health, 
software development and systems integration.  Its systems and processes enable better decision-making at the point of care and 
full integration of medical information across different platforms.  This acquisition has enabled ManTech to expand its customer 
relationships and deliver IT solutions through Evolvent's existing relationships with the Department of Defense health organizations, 
the Veterans Administration and the Department of Health and Human Services.  ManTech funded the acquisition with cash on 
hand. The equity purchase agreement did not contain provisions for contingent consideration.   

Revenues were $27.9 million and net income was $0.3 million for the period from January 6, 2012 to December 31, 2012.  
For the year ended December 31, 2012, the Company incurred $0.2 million of acquisition costs associated with the Evolvent 
transaction, which are included in general and administrative expense in our consolidated statement of income and loss.   

The purchase price of $39.9 million was allocated to the underlying assets and liabilities based on their fair value at the date 
of  acquisition.    Total  assets  were  $46.9  million,  including  goodwill  and  intangible  assets  recognized  in  connection  with  the 
acquisition, and total liabilities were $7.0 million.  Included in total assets were $3.7 million in acquisition related intangible assets.  
We recorded goodwill of $33.2 million, which is not deductible for tax purposes.  Recognition of goodwill is largely attributed to 
the highly skilled employees and the value paid for Evolvent's capabilities in providing IT services and solutions to the federal 
government healthcare sector.

In allocating the purchase price, we considered among other factors, analyses of historical performance and estimates of future 
performance of Evolvent's contracts.  The components of other intangible assets associated with the acquisition were customer 
relationships and backlog valued at $3.4 million and $0.3 million, respectively.  Customer contracts and related relationships 
represent the underlying relationships and agreements with Evolvent's existing customers. Customer relationships and backlog 
are amortized over their estimated useful lives of 20 years and 1 year, respectively, using the pattern of benefits method.  The 
weighted-average amortization period for the intangible assets is 18.5 years. 

Worldwide  Information  Network  Systems,  Inc.-On  November 15,  2011,  we  completed  the  acquisition  of  Worldwide 
Information Network Systems, Inc. (WINS).  The results of WINS' operations have been included in our consolidated financial 
statements since that date.  The acquisition was completed through a stock purchase agreement dated October 26, 2011, by and 
among a subsidiary of ManTech International Corporation, WINS and its sole shareholder.  WINS provides IT solutions with 
network engineering and cyber security technical expertise to the Department of Defense, Department of State and other agencies.  
WINS' largest customer is the Defense Intelligence Agency (DIA) through its prime position on the Solutions for the Information 
Technology Enterprise (SITE) Indefinite Delivery/Indefinite Quantity contract vehicle.   This acquisition broadened our footprint 
in the high-end defense and intelligence market.  The addition of WINS' IT capabilities, its prime position on the DIA SITE contract, 
support of the Department of State and other contracts will enhance our positioning with important customers and further our 
growth prospects.   ManTech funded the acquisition with cash on hand.  The stock purchase agreement did not contain provisions 
for contingent consideration.  

Revenues were $8.5 million and net income was $0.7 million for the period from November 15, 2011 to December 31, 2011.  
The Company incurred in fiscal year 2011 approximately $0.6 million of acquisition costs related to the WINS transaction, which 
are included in general and administrative expense in our consolidated statement of income and loss for the year ended December 
31, 2011. 

The purchase price of $90.4 million was allocated to the underlying assets and liabilities based on their fair values at the date 
of acquisition.  Total assets were $100.5 million, including goodwill and intangible assets recognized in connection with the 
acquisition, and total liabilities were $10.1 million.  Included in total assets were $18.7 million in acquired intangible assets.  We 
recorded goodwill of $62.5 million, which will be deductible for tax purposes over 15 years, assuming adequate levels of taxable 

52

income.  Recognition of goodwill is largely attributed to the highly skilled employees and the value paid for WINS' capabilities 
in supporting high-end defense, intelligence and homeland security markets.  

In allocating the purchase price, we consider among other factors, analyses of historical financial performance and estimates 
of future performance of WINS' contracts.  The components of other intangible assets associated with the acquisition were customer 
relationships and backlog valued at $18.0 million and $0.7 million, respectively.  Customer contracts and related relationships 
represent the underlying relationships and agreements with WINS' existing customers.  Customer relationships and backlog are 
amortized over their estimated useful lives of 20 years and 1 year, respectively, using the pattern of benefits method.  The weighted-
average amortization period for the intangible assets is 19.3 years.

TranTech, Inc.-On February 11, 2011, we completed the acquisition of TranTech, Inc. (TranTech).  The results of TranTech's 
operations have been included in our consolidated financial statements since that date.  The acquisition was completed through a 
stock purchase agreement dated February 11, 2011, by and among ManTech International Corporation, TranTech and its sole 
shareholder.  TranTech provides information technology, networking and cyber security services to the federal government.  This 
acquisition  allows  us  to  continue  extending  our  presence  in  the  defense,  security  and  intelligence  communities,  and  to  offer 
comprehensive solutions through a prime position on the Defense Information Systems Agency ENCORE II contract.  ManTech 
funded the acquisition with cash on hand.  The stock purchase agreement did not contain provisions for contingent consideration.   

Revenues were $12.5 million and net income was $0.9 million for the period from February 11, 2011 to December 31, 2011.  
The Company incurred in fiscal year 2011 approximately $0.3 million of acquisition costs related to the TranTech transaction, 
which are included in general and administrative expense in our consolidated statement of income and loss for the year ended 
December 31, 2011. 

The purchase price of $21.5 million was allocated to the underlying assets and liabilities based on their fair value at the date 
of  acquisition.    Total  assets  were  $23.8  million,  including  goodwill  and  intangible  assets  recognized  in  connection  with  the 
acquisition, and total liabilities were $2.3 million.  Included in total assets were $5.0 million in acquired intangible assets.  We 
recorded goodwill of $14.6 million, which will be deductible for tax purposes over 15 years, assuming adequate levels of taxable 
income.  Recognition of goodwill is largely attributed to the value paid for TranTech's capabilities in supporting high-end defense, 
intelligence and homeland security markets.  

In allocating the purchase price, we consider among other factors, analyses of historical financial performance and estimates 
of future performance of TranTech's contracts.  The components of other intangible assets associated with the acquisition were 
customer  relationships  and  backlog  valued  at  $4.6  million  and  $0.4  million,  respectively.    Customer  contracts  and  related 
relationships represent the underlying relationships and agreements with TranTech's existing customers.  Customer relationships 
and backlog are amortized over their estimated useful lives of 20 years and 1 year, respectively, using the pattern of benefits 
method.  The weighted-average amortization period for the intangibles assets is 18.5 years. 

Pro Forma Financial Information-We calculated the following unaudited pro forma amounts as if our acquisitions had 
occurred on January 1, 2012.  Our consolidated pro forma revenue would have been $2,310.2 million and $2,591.9 million and 
our consolidated pro forma net income (loss) would have been $(6.0) million and $95.7 million for the years ended December 31, 
2013 and 2012, respectively.  

4.  Earnings (Loss) per Share 

Under ASC 260, Earnings per Share, the two-class method is an earnings (loss) allocation formula that determines earnings 
(loss) per share for each class of common stock according to dividends declared (or accumulated) and participation rights in 
undistributed earnings (loss).  Under that method, basic and diluted earnings (loss) per share data are presented for each class of 
common stock.

In applying the two-class method, we determined that undistributed earnings (loss) should be allocated equally on a per share 
basis between Class A and Class B common stock.  Under our Certificate of Incorporation, the holders of the common stock are 
entitled to participate ratably, on a share-for-share basis as if all shares of common stock were of a single class, in such dividends, 
as may be declared by the Board of Directors.  During the years ended December 31, 2013 and 2012, we declared and paid quarterly 
dividends, each in the amount of $0.21 per share on both classes of common stock.  During December 31, 2011, we declared and 
paid semi-annual dividends, each in the amount of $0.42 per share on both classes of common stock.

Basic earnings (loss) per share has been computed by dividing net income (loss) available to common stockholders by the 
weighted average number of shares of 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 in which the shares were outstanding.  Diluted earnings 
53

           
    
(loss) per share has been computed in a manner consistent with that of basic earnings (loss) per share while giving effect to all 
potentially dilutive common shares that were outstanding during each period. 

The net income (loss) available to common stockholders and weighted average number of common shares outstanding used 
to  compute basic and diluted earnings (loss) per share for each class of common stock are as follows (in thousands, except per 
share amounts): 

Distributed earnings
Undistributed earnings (loss)

For the years ended December 31, 2013, 2012 and 2011, options to purchase 3.2 million, 2.9 million and 2.2 million shares, 
respectively, were outstanding but not included in the computation of diluted earnings (loss) per share because the options' effect 
would have been anti-dilutive.  For the years ended December 31, 2013, 2012 and 2011, there were 79,567 shares, 38,542 shares, 
and 271,165 shares, respectively, issued from the exercise of stock options.

Amounts billable consist principally of amounts to be billed within the next month.  Revenues recorded in excess of funding 
are billable upon receipt of contractual amendments or other modifications.  Revenues recorded in excess of milestone billings 
on  fixed  price  contracts  consist  of  amounts  not  expected  to  be  billed  within  the  next  month.   The  retainage  is  billable  upon 
completion of the contract performance and approval of final indirect expense rates by the government.  There is a contract with 
the U.S. Army that represents 15.3%  of receivables-net at December 31, 2013 and multiple contracts with the U.S. Army that 
represent  28.0%  of  receivables-net  at  December 31,  2012.   Accounts  receivable  at  December 31,  2013  are  expected  to  be 
substantially collected within one year except for approximately $1.5 million, of which 91.2% is related to receivables from sales 
to the U.S. government.  The remainder is related to receivables from contracts in which we acted as a subcontractor to other 
contractors.

The Company does not believe it has significant exposure to credit risk as accounts receivable and the related unbilled amounts 
are  primarily  due  from  the  U.S.  government.    The  allowance  for  doubtful  accounts  represents  our  estimate  for  exposure  to 
compliance, contractual issues and bad debts related to prime contractors.

7.  Goodwill and Other Intangible Assets

Under ASC 350, Intangibles - Goodwill and Other, goodwill is to be reviewed at least annually for impairment and whenever 
events or circumstances indicate that the carrying value of goodwill may not be fully recoverable.  We have elected to perform 
this review during the second quarter of each calendar year.  The goodwill impairment test is a two-step process performed at the 
reporting unit level.  The first step of the goodwill impairment test compares the fair value of a reporting unit with its carrying 
amount (including goodwill).  If the reporting unit's fair value exceeds its carrying value, no further procedures are required.  
However, if the reporting unit's fair value is less than its carrying value, an impairment of goodwill may exist, requiring a second 
step to be performed.  Step two of this test measures the amount of the impairment loss, if any.  Step two of this test requires the 
allocation of the reporting unit's fair value to its assets and liabilities, including any unrecognized intangible assets, in a hypothetical 
analysis that calculates the implied fair value of goodwill as if the reporting unit were being acquired in a business combination.  
If the implied fair value of goodwill is less than the carrying value, the difference is recorded as a goodwill impairment charge in 
operations.  

The fair values of the reporting units are determined based on a weighting of the income approach, market approach and 
market transaction approach.  The income approach is a valuation technique in which fair value is based from forecasted future 
cash flow discounted at the appropriate rate of return commensurate with the risk as well as current rates of return for equity and 
debt capital as of the valuation date.  The forecast used in our estimation of fair value was developed by management based on a 
contract basis, incorporating adjustments to reflect known contract and market considerations (such as reductions and uncertainty 
in government spending, pricing pressure and opportunities).  The discount rate utilizes a risk adjusted weighted average cost of 
capital.  The market approach is a valuation technique in which the fair value is calculated based on market prices realized in an 
actual arm's length transaction.  The technique consists of undertaking a detailed market analysis of publicly traded companies 
that provides a reasonable basis for comparison to the company.  Valuation ratios, which relate market prices to selected financial 
statistics derived from comparable companies, are selected and applied to the company after consideration of adjustments for 
financial position, growth, market, profitability and other factors.  The market transaction approach is a valuation technique in 
which the fair value is calculated based on market prices realized in actual arm's length transactions.  The technique consists of 
undertaking a detailed market analysis of merged and acquired companies that provided a reasonable basis for comparison to the 
company.  Valuation ratios, which relate market prices to selected financial statistics derived from comparable companies, are 
selected and applied to the company after consideration of adjustments for financial position, growth, market, profitability and 
other factors.  To assess the reasonableness of the calculated reporting unit fair values, we compare the sum of the reporting units' 
fair values to the Company's market capitalization (per share stock price times the number of shares outstanding) and calculate 
an implied control premium (the excess of the sum of the reporting units' fair values over the market capitalization) and then assess 
the reasonableness of our implied control premium.   

During the second quarter, we completed our annual goodwill impairment test.  The results of step one of this test showed 
the fair value of all reporting units were substantially in excess of their carrying value, therefore, no impairment loss was identified 
and performance of step two was not required.  

During  the  fourth  quarter  of  2013,  multiple  events  and  circumstances  indicated  a  significant  reduction  in  the  operating 
performance  outlook  of  one  of  our  reporting  units.    These  events  included  lower  than  expected  contract  awards  on  several 
competitive  opportunities,  changing  mission  priorities  of  the  U.S.  government  in  relation  to  our  Command,  Control, 
Communications,  Computers,  Intelligence,  Surveillance,  and  Reconnaissance  (C4ISR)  contracts  and  Overseas  Contingency 
Operations  (OCO)-related  work  (primarily  on  maintenance  and  sustainment  of  Mine-Resistant Ambush-Protected  (MRAP) 
vehicles, delays in our customers' procurement cycle due, in part, to the U.S. government shutdown, and continued margin pressures 
on some of our contracts.  The culmination of these events led us to conduct an interim goodwill impairment test.  The results of 
step one of this test showed the carrying value of one reporting unit was in excess of its fair value, therefore we performed step 
two of the goodwill impairment test to measure the amount of the impairment loss.  Based on the results of the step two analysis, 
we recorded a non-cash goodwill impairment charge of $118.4 million for the period ending December 31, 2013.

Revolving Credit Facility-We maintain a credit agreement with a syndicate of lenders led by Bank of America, N.A., as 
administrative agent.  The credit agreement provides for a $500.0 million revolving credit facility, with a $25.0 million letter of 
credit sublimit and a $30.0 million swing line loan sublimit.  The credit agreement also contains an accordion feature that permits 

57

the Company to arrange with the lenders for the provision of up to $250.0 million in additional commitments.  The maturity date 
for the credit agreement is October 12, 2016.  

Borrowings under our credit agreement are collateralized by substantially all the assets of ManTech and its Material Subsidiaries 
(as defined in the credit agreement) and bear interest at one of the following variable rates as selected by the Company at the time 
of borrowing: a London Interbank Offer Rate (LIBOR) based rate plus market spreads (1.25% to 2.25% based on our consolidated 
total leverage ratio) or Bank of America's base rate plus market spreads (0.25% to 1.25% based on our consolidated total leverage 
ratio).  The aggregate annual weighted average interest rates were 0.00% and 0.05% for the years ended December 31, 2013 and 
2012, respectively.

The terms of the credit agreement permit prepayment and termination of the loan commitments at any time, subject to certain 
conditions.  The credit agreement requires the Company to comply with specified financial covenants, including the maintenance 
of a certain consolidated leverage ratios and a certain fixed charge coverage ratio.  The credit agreement also contains various 
covenants,  including  affirmative  covenants  with  respect  to  certain  reporting  requirements  and  maintaining  certain  business 
activities, and negative covenants that, among other things, may limit or impose restrictions on our ability to incur liens, incur 
additional  indebtedness,  make  investments,  make  acquisitions  and  undertake  certain  additional  actions.   As  of,  and  during, 
December 31, 2013 and 2012, we were in compliance with our financial covenants under the credit agreement.  

There was no outstanding balance on our revolving credit facility at December 31, 2013 and 2012.  The weighted average 
borrowings under the revolving portion of the facility during the years ended December 31, 2013 and 2012 were $0 and $38 
thousand, respectively.  The maximum available borrowing under the revolving credit facility at December 31, 2013 was $499.8 
million.  At December 31, 2013 and 2012, we were contingently liable under letters of credit totaling $0.2 million and $0.2 million, 
respectively, which reduces our availability to borrow under our revolving credit facility.

The following table summarizes the activity under our revolving credit facility for the years ended December 31, 2013, 2012 

and 2011 (in thousands):

7.25% Senior Unsecured Notes-We have $200.0 million in aggregate principal amount of 7.25% senior unsecured notes that 
are registered under the Securities Act of 1933, as amended.  The fair value of the 7.25% senior unsecured notes as of December 31, 
2013 was approximately $210.0 million based on quoted market prices.

The 7.25% senior unsecured notes were issued on April 13, 2010 and mature on April 15, 2018 with interest payable semi-
annually in April and October.   The 7.25% senior unsecured notes were issued at 100% of the aggregate principal amount and 
are effectively subordinate to our existing and future senior secured debt (to the extent of the value of the assets securing such 
debt), including debt outstanding under our revolving credit facility.  The 7.25% senior unsecured notes may be redeemed, in 
whole or in part, at any time, at the option of the Company, subject to certain conditions specified in the indenture governing the 
7.25% senior unsecured notes.  We have determined that we will redeem these notes in accordance with their terms in April 2014.  
The 7.25% senior unsecured notes are guaranteed, jointly and severally, on a senior unsecured basis by each of our 100% owned 
domestic subsidiaries that also guarantees debt obligations under our prior revolving credit facility or will guarantee debt obligations 
under our revolving credit facility.

The issuance costs incurred by the Company are being amortized to interest expense over the contractual life of the 7.25% 

senior unsecured notes using the effective interest rate method, resulting in an effective rate of 7.67%.

The  indenture  governing  the  7.25%  senior  unsecured  notes  contains  customary  events  of  default,  as  well  as  restrictive 
covenants, which, subject to important exceptions and qualifications specified in such indenture, will, among other things, limit 
our ability and the ability of our subsidiaries that guarantee the 7.25% senior unsecured notes to: pay dividends or distributions, 
repurchase equity, prepay subordinated debt or make certain investments; incur additional debt or issue certain disqualified stock 
and preferred stock; incur liens on assets; merge or consolidate with another company or sell all or substantially all assets; and 
allow to exist certain control provisions.  An event of default under the indenture will allow either the trustee of the notes or the 
holders of at least 25% in principal amount of the then outstanding notes to accelerate, or in certain cases, will automatically cause 

58

the acceleration of, the amounts due under the notes.  As of December 31, 2013 and 2012, the Company was in compliance with 
all required covenants under the indenture.  

9.  Commitments and Contingencies 

Contracts with the U.S. government including subcontracts are subject to extensive legal and regulatory requirements and, 
from time to time, agencies of the U.S. government, in the ordinary course of business, investigate whether our operations are 
conducted in accordance with these requirements and the terms of the relevant contracts. U.S. government investigations of the 
Company, whether related to our U.S. government contracts or conducted for other reasons, could result in administrative, civil 
or criminal liabilities, including repayments, fines or penalties being imposed upon the Company, or could lead to suspension or 
debarment from future U.S. government contracting. Management believes it has adequately reserved for any losses that may be 
experienced from any investigation of which it is aware. The Defense Contract Audit Agency (DCAA) has completed our incurred 
cost audits through 2005, with no material adjustments.  The remaining audits for 2006 through 2013 are not expected to have a 
material effect on our financial position, results of operations or cash flow and management believes it has adequately reserved 
for any losses.   

In the normal course of business, we are involved in certain governmental and legal proceedings, claims and disputes and 
have litigation pending under several suits.  We believe that the ultimate resolution of these matters will not have a material effect 
on our financial position, results of operations or cash flows.  

We lease office space and equipment under long-term operating leases.  A number of the leases contain renewal options and 
escalation clauses.  At December 31, 2013, aggregate future minimum rental commitments under these leases are as follows (in 
thousands):

Office space and equipment rent expense totaled approximately $47.6 million, $52.1 million and $55.2 million for the years 

ended December 31, 2013, 2012 and 2011, respectively. 

We had $11.0 million and $9.3 million of deferred rent liabilities resulting from recording rent expense on a straight-line basis 

over the life of the respective lease for the years ended December 31, 2013 and 2012, respectively. 

10.  Stockholders' Equity and Stock-Based Compensation 

Common Stock-We have 150,000,000 shares of authorized Class A common stock, par value $0.01 per share.  We have 
50,000,000 shares of authorized Class B common stock, par value $0.01 per share.  On December 31, 2013, there were 24,001,780 
shares of Class A common stock outstanding, 244,113 shares of Class A common stock recorded as treasury stock and 13,192,845 
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 George J. Pedersen (our Chairman of the Board and CEO), 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. 

59

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 our assets or funds legally and contractually 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 Mr. Pedersen, all outstanding shares of Class B common stock automatically 
convert to Class A common stock. 

Preferred Stock-We are 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 our Board of Directors upon issuance.  The rights, preferences and privileges 
of holders of our common stock are subject to, and may be adversely affected by, the rights of holders of any shares of preferred 
stock that we may designate and issue in the future.  At December 31, 2013 and 2012, no shares of preferred stock were outstanding 
and the Board of Directors currently has no plans to issue a series of preferred stock. 

Accounting for Stock-Based Compensation:

Our 2011 Management Incentive Plan (the Plan) was designed to attract, retain and motivate key employees.  Awards granted 
under the Plan are settled in shares of Class A common stock.  At the beginning of each year, the Plan provides that the number 
of shares available for issuance automatically increases by an amount equal to 1.5% of the total number of shares of Class A and 
Class B common stock outstanding on December 31st of the previous year.  On January 2, 2014, there were 557,894 additional 
shares made available for issuance under the Plan.  Through December 31, 2013, the remaining aggregate number of shares of 
our common stock authorized for issuance under the Plan was 3,521,356.  Through December 31, 2013, there were 4,616,309 
shares of our Class A common stock that were issued and remain outstanding as a result of equity awards granted under the Plan.  
The Plan expires in May 2021.

The Plan is administered by the compensation committee of our Board of Directors, along with its delegates.  Subject to the 
express provisions of the Plan, the committee has the Board of Directors' authority to administer and interpret the Plan, including 
the discretion to determine the exercise price, vesting schedule, contractual life and the number of shares to be issued.

Stock Compensation Expense-For the years ended December 31, 2013, 2012 and 2011, we recorded $5.2 million, $8.1 million 
and $9.2 million of stock-based compensation expense, respectively.  No compensation expense of employees with stock awards, 
including stock-based compensation expense, was capitalized during the periods.  For the years ended December 31, 2013, 2012 
and 2011, the total recognized tax deficiency from the exercise of stock options, vested cancellations and the vesting of restricted 
stock were $2.3 million, $1.4 million and $0.2 million, respectively.

Stock Options-We typically issue options that vest over three years in equal installments beginning on the first anniversary 
of the date of grant.  Under the terms of the Plan, the contractual life of the option grants may not exceed eight years.  During the 
years ended December 31, 2013 and 2012, we issued options that expire five years from the date of grant.  

Fair Value Determination-We have used the Black-Scholes-Merton option pricing model to determine fair value of our 
awards on date of grant.  We will reconsider the use of the Black-Scholes-Merton model if additional information becomes available 
in the future that indicates another model would be more appropriate or if grants issued in future periods have characteristics that 
cannot be reasonably estimated under this model.  

The following weighted-average assumptions were used for option grants during the years ended December 31, 2013, 2012 

and 2011:

Volatility-The expected volatility of the options granted was estimated based upon historical volatility of our share price 

through weekly observations of our trading history.

Expected Term-The expected term of options granted to employees during fiscal years 2013, 2012 and 2011 was determined 
from historical exercises of the grantee population.  For all grants valued during fiscal years 2013, 2012 and 2011, the options 

60

have graded vesting over three years in equal installments beginning on the first anniversary of the date of the grant and a contractual 
term of five years.

Risk-free Interest Rate-The yield on zero-coupon U.S. Treasury strips was used to extrapolate a forward-yield curve. This 
“term structure” of future interest rates was then input into a numeric model to provide the equivalent risk-free rate to be used in 
the Black-Scholes-Merton model based on expected term of the underlying grants.  

Dividend Yield-The Black-Scholes-Merton valuation model requires an expected dividend yield as an input.  We have calculated 

our expected dividend yield based on an expected annual cash dividend of $0.84 per share.

The following table summarizes weighted-average assumptions used in our calculations of fair value for the years ended 

December 31, 2013, 2012 and 2011:

Stock Option Activity-During the year ended December 31, 2013, we granted stock options to purchase 957,525 shares of 
Class A common stock at a weighted-average exercise price of $27.42 per share, which reflects the fair market value of the shares 
on the date of grant.  The weighted-average fair value of options granted during the years ended December 31, 2013, 2012 and 
2011, as determined under the Black-Scholes-Merton valuation model, was $4.84, $5.19 and $9.14, respectively.  These options 
vest over three years in equal annual installments beginning on the first anniversary of the date of the grant and have a contractual 
term of five years.  Option grants that vested during the years ended December 31, 2013, 2012 and 2011 had a combined fair value 
of $6.1 million, $8.3 million and $7.8 million, respectively.

Unrecognized compensation expense related to outstanding stock options expected to vest as of December 31, 2013 was $5.5 
million, which is expected to be recognized over a weighted-average period of 1.6 years and will be adjusted for any future changes 
in estimated forfeitures.

Restricted Stock-Under the Plan, we have issued restricted stock.  A restricted stock award is an issuance of shares that cannot 
be sold or transferred by the recipient until the vesting period lapses.  Restricted shares granted to employees vest over three years 
in equal installments beginning on the first anniversary of the grant date, contingent upon employment with the Company on the 
vesting dates.  Restricted shares granted to our Board of Directors vest in one year.  The related compensation expense is recognized 
over the service period and is based on the grant date fair value of the stock and the number of shares expected to vest.

11.  Retirement Plans 

As of December 31, 2013, we maintained a qualified defined contribution plan.  Our qualified defined contribution plan covers 
substantially all employees and complies with Section 401 of the Internal Revenue Code.  Under this plan, we stipulated a basic 
matching contribution that matches a portion of the participants' contribution based upon a defined schedule.  Additionally, this 
plan contains a discretionary contribution component where the Company may contribute additional amounts based on a percentage 
of eligible employees' compensation.  Contributions are invested by an independent investment company.  The choice of investment 
alternatives is at the election of each participating employee.  Our contributions to the plan were approximately $19.3 million, 
$22.6 million and $23.8 million for the years ended December 31, 2013, 2012 and 2011, respectively. 

We maintained an Employee Stock Ownership Plan (ESOP) as of December 31, 2013.  On December 18, 1998, the Board of 
Directors approved the establishment of a qualified ESOP, effective January 1, 1999, for the benefit of substantially all of our U.S. 
domestic-based employees and some overseas employees.  The ESOP is non-leveraged and is 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 our annual contribution to the ESOP is at the discretion of our Board 
of Directors.  For the years ended December 31, 2013, 2012 and 2011, we recorded $0.9 million, $3.8 million and $3.6 million, 
respectively, as compensation expense related to ESOP contributions.  There were 31,653 shares, 146,589 shares and 116,087 
shares of Class A common stock contributed to the ESOP for the years ended December 31, 2013, 2012 and 2011, respectively.  
There were no unearned ESOP shares at December 31, 2013 and 2012, respectively.  As required under ASC 714-40, 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.  For the years ended December 31, 2013, 
2012 and 2011, new shares were issued to satisfy this obligation.

As of December 31, 2013, we also maintained an Employee Supplemental Savings Plan (ESSP), a non-qualified deferred 
compensation plan, for certain key employees.  Under this plan, eligible employees may defer up to 75% of qualified annual base 
compensation and 100% of bonus.  In the ESSP, participant deferral accounts are credited with a rate of return based on investment 
elections as selected by the participant.  The assets related to the ESSP are held in a rabbi trust owned by the Company for benefit 
of the participating employees.  The trust investments are in the form of variable universal life insurance products, which are 
owned  by  the  Company.    These  investments  seek  to  replicate  the  return  of  the  participant  investment  elections.    Employee 
contributions to this plan were approximately $3.2 million, $5.1 million and $4.5 million for the years ended December 31, 2013, 
2012 and 2011, respectively.

We maintained a nonqualified supplemental defined benefit pension plan for certain retired employees of an acquired company 
as of December 31, 2013.  These plans were informally and partially funded beginning in 1999 through a rabbi trust.  Assets held 
in a rabbi trust are not eligible to be included in the calculation of plan status.  At both December 31, 2013 and 2012, 100% of the 
rabbi trust assets were invested in a money market account with a commercial bank.  All covered employees retired prior to 1998.  
Our benefit obligation at December 31, 2013 and 2012 was $1.3 million and $1.4 million, respectively.

For the year ended December 31, 2013, the non-current benefit for income taxes includes $(2.4) million arising from the 
cancellation of vested stock options allocated to equity and valuation differences between grant and vesting dates on restricted 
stock allocated to equity and $(0.1) million related to liabilities for uncertain tax positions.  For the year ended December 31, 
2012, the non-current benefit for income taxes includes $(1.4) million arising from the cancellation of vested stock options allocated 
to equity and valuation differences between grant and vesting dates on restricted stock allocation to equity and $(0.1) million 
related to liabilities for uncertain tax positions (including $(0.1) million for use of a state net operating loss).  For the year ended 
December 31, 2011, the non-current benefit for income taxes includes $0.2 million for amounts arising from the exercise of stock 
options allocated as equity; $(0.4) million arising from the cancellation of vested stock options allocated to equity and valuation 
differences between grant and vesting dates on restricted stock allocated to equity; and $(0.7) million related to liabilities for

The tax benefits associated with nonqualified stock options and disqualifying dispositions of incentive stock options reduced 
the current taxes payable by $0.1 million for the year ended December 31, 2013.  These benefits were recorded as an increase to 
additional paid-in capital. 

At December 31, 2013, we had state net operating losses of approximately $0.3 million that expire beginning 2016 through 

2032; and federal net operating losses of $1.6 million that expire in 2031 and 2032.

The total liability for gross unrecognized tax benefits as of December 31, 2013, 2012 and 2011 includes $0.9 million, $1.0 
million and $1.1 million, respectively, of unrecognized net tax benefits which, if ultimately recognized, would reduce our annual 
effective tax rate in a future period.

The Company is subject to income taxes in the U.S., various state and foreign jurisdictions.  Tax statutes and regulations 
within each jurisdiction are subject to interpretation and require significant judgment to apply.  The Company is no longer subject 

65

to U.S., state or non-U.S. income tax examinations by tax authorities for the years before 2009.  The Company believes it is 
reasonably possible that $0.6 million of gross unrecognized tax benefits will be settled within the next year due to expirations of 
statute of limitations.

The  Company  recognizes  interest  related  to  unrecognized  tax  benefits  within  interest  expense  and  penalties  related  to 
unrecognized tax benefits in general and administrative expenses.  At December 31, 2013, 2012 and 2011, interest and penalties 
on the net unrecognized tax benefits were $0.2 million, $0.2 million and $0.2 million, respectively.  

13.  Business Segment and Geographic Area Information 

We have one reportable segment.  We deliver a broad array of information technology and technical services solutions under 
contracts with the U.S. government.  Our 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 our services as a separate 
customer so long as that customer has independent decision-making and contracting authority within its organization.  The U.S. 
Army Tank-Automotive Armament Command (TACOM) contract accounted for 19.4%, 22.2% and 17.0% of our revenues and 
12.8%, 19.3% and 17.3% of our operating income (excluding the goodwill impairment) for the years ended December 31, 2013, 
2012 and 2011.  Revenues from the U.S. government under prime contracts and subcontracts were approximately 99.0%, 99.2% 
and 99.2% of our total revenues for the years ended December 31, 2013, 2012 and 2011, respectively.  We treat sales to U.S. 
government customers as sales within the United States regardless of where the services are performed.  Furthermore, substantially 
all assets from continuing operations were held in the United States for the years ended December 31, 2013, 2012 and 2011.

Disclosure  items  required  under ASC  280,  Segment  Reporting,  including  goodwill  impairment,  interest  income,  interest 
expense,  depreciation  and  amortization  expense,  costs  for  stock-based  compensation  programs,  certain  unallowable  costs  as 
determined under Federal Acquisition Regulations and expenditures for segment assets are not applicable as we review those items 
on a consolidated basis.

14.  Equity Method Investments

On May 24, 2012, Fluor-ManTech Logistics Solutions, LLC (FMLS), a limited liability company, was created with Fluor 
International, Inc. and ManTech as the investees.  Each investee has a 50% ownership interest in FMLS.  Because we have the 
ability to exercise significant influence over FMLS we determined that the equity method of accounting will be used for our 
investment.  Under the operating agreement, we are required to provide additional financial support for losses incurred by FMLS. 
FMLS had no assets at December 31, 2013 and 2012.  FMLS liabilities were $1.7 million  and $0 at December 31, 2013 and 2012, 
respectively.  FMLS had no revenues for the years ended December 31, 2013 and 2012.  FMLS net loss was $(1.7) million and 
no net loss for the years ended December 31, 2013 and 2012, respectively.  We recorded $(0.9) million and $0 in equity method 
losses for the years ended December 31, 2013 and 2012, respectively. 

15.  Sale of Investment 

ManTech received $3.3 million, $0.2 million and $0.2 million in proceeds during the years ended December 31, 2011, 2012 
and 2013, respectively, for the sale of our investment of less than 5% in NetWitness Corporation (NetWitness).  At December 31, 
2013, there was $0.1 million held in escrow, which we expect to collect next year.  The transaction was consummated on April 1, 
2011 pursuant to an agreement and plan of merger dated March 12, 2011 by and among EMC Corporation, NetWitness and certain 
persons acting as the representative for the shareholders of NetWitness.  The sale of our investment resulted in a pre-tax gain of 
$3.7 million, which was recorded in other income in our consolidated statement of income and loss for the year ended December 31, 
2011.

The quarterly financial data reflects, in the opinion of the Company, all normal and recurring adjustments to present fairly 

the results of operations for such periods.  Results of any one or more quarters are not necessarily indicative of annual results or 
continuing trends.  The following tables set forth selected unaudited quarterly financial data (the quarter ending December 31, 
2013 contains a goodwill impairment charge of $118.4 million):

Management has evaluated subsequent events after the balance sheet date through the financial statements issuance date for 

appropriate accounting and disclosure.     

Acquisition of Allied Technology Group, Inc.

On  February 18,  2014,  we  completed  the  acquisition  of Allied  Technology  Group,  Inc.  (ATG).   ATG  is  an  innovative 
engineering and information management solution company with strong customer relationships and strategic contracts with the 
Department  of  Homeland  Security  (DHS).   ATG  is  a  privately  held  company  providing  IT,  engineering  services,  program 
management and training solutions to a variety of federal customers.  The acquisition will enable us to deliver services through 
their unrestricted prime position on DHS's primary acquisition vehicles; the Technical, Acquisition and Business Support Services 
and the Enterprise Acquisition Gateway for Leading Edge Solutions II.  We funded the acquisition with cash on hand.  The purchase 
price was $45.0 million.

Item 9. 

Changes in and Disagreements with Accountants on Accounting and Financial Disclosure 

The Company has had no disagreements with its auditors on accounting principles, practices or financial statement disclosure 

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

Item 9A. 

Controls and Procedures 

We performed an assessment as of December 31, 2013 of the effectiveness of the design and operation of our disclosure 
controls and procedures and our internal control over financial reporting.  This assessment was done under the supervision and 
with the participation of management, including our principal executive officer and principal financial officer.  Included as Exhibits 
31.1 and 31.2 to this Annual Report on Form 10-K are forms of “Certification” of our principal executive officer (our Chairman 
of the Board and Chief Executive Officer) and our principal financial officer (our Chief Financial Officer).  The forms of Certification 
are required in accordance with Section 302 of the Sarbanes-Oxley Act of 2002.  This section of the Annual Report on Form 10-
K that you are currently reading is the information concerning the assessment referred to in the Section 302 certifications and 
required by the rules and regulations of the SEC.  You should read this information in conjunction with the Section 302 certifications 
for a more complete understanding of the topics presented. 

Disclosure  Controls  and  Procedures  and  Internal  Control  over  Financial  Reporting-Management  is  responsible  for 
establishing and maintaining adequate disclosure controls and procedures and internal control over financial reporting. Disclosure 
controls and procedures are designed to provide reasonable assurance that information required to be disclosed in our reports filed 
or submitted under the Exchange Act, such as this Annual Report on Form 10-K, is accurately recorded, processed, summarized 
and reported within the time periods specified in the SEC's rules and forms.  Disclosure controls and procedures are also designed 
to  provide  reasonable  assurance  that  such  information  is  accumulated  and  communicated  to  our  management,  including  our 
principal executive officer and our principal financial officer, as appropriate to allow timely decisions regarding required disclosure. 

Internal control over financial reporting is a process designed by, or under the supervision of our principal executive officer 
and our principal financial officer, and effected by our Board of Directors, management and other personnel, to provide reasonable 
assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in 
accordance with GAAP and includes those policies and procedures that: 

• 

• 

• 

pertain  to  the  maintenance  of  records  that  in  reasonable  detail  accurately  and  fairly  reflect  the  transactions  and 
dispositions of our assets;

provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements 
in  accordance  with  GAAP  and  that  our  receipts  and  expenditures  are  being  made  only  in  accordance  with 
authorizations of management or our Board of Directors; and

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition 
of our assets that could have a material adverse effect on our financial statements.

Limitations on the Effectiveness of Controls-Management, including our principal executive officer and our principal financial 
officer, do not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all 
errors and all fraud.  A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, 
assurance that the objectives of the control system are met.  Further, the design of a control system must reflect the fact that there 
are resource constraints and the benefits of controls must be considered relative to their costs.  Because of the inherent limitations 
in all control systems, no assessment of controls can provide absolute assurance that all control issues and instances of fraud, if 
any, within the Company have been detected.  These inherent limitations include the realities that judgments in decision-making 
can be faulty and that breakdowns can occur because of simple error or mistake.  Additionally, controls can be circumvented by 
the individual acts of some persons, by collusion of two or more people, or by management's override of the control.  The design 
of any system of controls also is based in part upon certain assumptions about the likelihood of future events and there can be no 
assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may 
become inadequate because of changes in conditions or the degree of compliance with the policies or procedures may deteriorate.  
Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be 
detected. 

Scope of the Assessments-The assessment by our principal executive officer and our principal financial officer of our disclosure 
controls and procedures and the assessment by our management of our internal control over financial reporting included a review 
of procedures and documents and discussions with other employees in our organization in order to evaluate the adequacy of our 
internal control system design.  In the course of the evaluation, we sought to identify exposure to unprevented or undetected data 
69

errors, control problems or acts of fraud and to confirm that appropriate corrective action, including process improvements, were 
being undertaken.  The assessment also included testing of properly designed controls to verify their effective performance.  Our 
management used the criteria issued by the Committee of Sponsoring Organizations of the Treadway Commission in the 1992 
Internal Control-Integrated Framework to assess the effectiveness of our internal control over financial reporting. 

We assess our disclosure controls and procedures and our internal control over financial reporting on an ongoing basis so that 
the conclusions concerning controls effectiveness can be reported in our Quarterly Reports on Form 10-Q and Annual Reports on 
Form 10-K.  We consider the results of these assessment activities as we monitor our disclosure controls and procedures and our 
internal control over financial reporting.  Our intent is to ensure that disclosure controls and procedures and internal control over 
financial reporting will be maintained and updated as conditions warrant.  Among other matters, we sought in our assessment to 
determine whether there were any “material weaknesses” in our internal control over financial reporting, or whether we had 
identified any acts of fraud involving senior management, management or other personnel who have a significant role in our 
internal  control  over  financial  reporting.   This  information  was  important  both  for  the  assessment  generally  and  because  the 
Section 302 certifications require that our principal executive officer and our principal financial officer disclose that information, 
along with any “significant deficiencies,” to the Audit Committee of our Board of Directors, and to our independent auditors and 
to report on related matters in this section of the Annual Report on Form 10-K. 

Assessment of Effectiveness of Disclosure Controls and Procedures-Based upon the assessments, our principal executive 
officer and our principal financial officer have concluded that as of December 31, 2013 our disclosure controls and procedures 
were effective at the reasonable assurance level described above. 

Management's  Report  on  Internal  Control  over  Financial  Reporting-Management  is  responsible  for  establishing  and 
maintaining adequate control over financial reporting.  Management used the criteria issued by the Committee of Sponsoring 
Organizations of the Treadway Commission in the 1992 Internal Control-Integrated Framework to assess the effectiveness of our 
internal control over financial reporting.  Based upon the assessments, our management has concluded that as of December 31, 
2013 our internal control over financial reporting was effective.  Our independent registered public accounting firm issued an 
attestation report concerning our internal control over financial reporting, which appears further in this Annual Report. 

Changes in Internal Control over Financial Reporting-During the three months ended December 31, 2013, there were no 
changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, 
our internal control for financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

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

We  have  audited  the  internal  control  over  financial  reporting  of  ManTech  International  Corporation  and  subsidiaries  (the 
"Company") as of December 31, 2013, based on criteria established in Internal Control - Integrated Framework (1992) issued by 
the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission.   The  Company's  management  is  responsible  for 
maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over 
financial  reporting,  included  in  the  accompanying  Management's  Report  on  Internal  Control  over  Financial  Reporting.   Our 
responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).  
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control 
over financial reporting was maintained in all material respects.  Our audit included obtaining an understanding of internal control 
over  financial  reporting,  assessing  the  risk  that  a  material  weakness  exists,  testing  and  evaluating  the  design  and  operating 
effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in 
the circumstances.  We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal 
executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, 
management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation 
of financial statements for external purposes in accordance with generally accepted accounting principles.  A company's internal 
control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in 
reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable 
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally 
accepted  accounting  principles,  and  that  receipts  and  expenditures  of  the  company  are  being  made  only  in  accordance  with 
authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely 
detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial 
statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper 
management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis.  
Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject 
to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the 
policies or procedures may deteriorate. 

In  our  opinion,  the  Company  maintained,  in  all  material  respects,  effective  internal  control  over  financial  reporting  as  of 
December 31, 2013, based on the criteria established in Internal Control - Integrated Framework (1992) issued by the Committee 
of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 
consolidated financial statements and financial statement schedule as of and for the year ended December 31, 2013 of the Company 
and our report dated February 21, 2014 expressed an unqualified opinion on those financial statements and financial statement 
schedule.

FORWARD-LOOKING STATEMENT

This summary annual report contains “forward-looking” statements that ManTech believes to be within the definition in the Private Securities Litigation Reform 
Act of 1995. Such statements involve substantial risks and uncertainties, many of which are outside of our control. Words such as “may,” “will,” “expect,” “intend,” 
“anticipate,” “believe,” or “estimate,” or the negative of these terms or words of similar import are intended to identify forward-looking statements.

Although forward-looking statements in this summary annual report reflect our good-faith judgment, such statements can only be based on facts and factors 
currently known by us and are inherently subject to risks and uncertainties. Actual results and outcomes may differ materially from the results and outcomes 
we anticipate. Factors that could cause actual results to differ materially from the results we anticipate, include, but are not limited to, the following: adverse 
changes or delays in U.S. government spending for programs we support due to cost cutting and efficiency initiatives, changing mission priorities and other 
federal budget constraints generally; uncertainty regarding the timing and nature of government action to complete the budget and appropriations process, 
continue federal government operations and otherwise address budgetary constraints, or other factors; failure to compete effectively for new contract awards 
or to retain existing U.S. government contracts; failure to obtain option awards, task orders or funding under contracts; delays in the competitive bidding 
process caused by competitors’ protests of contract awards received by us or other factors; renegotiation, modification or termination of our contracts, or 
failure to perform in conformity with contract terms or our expectations; failure to realize the full amount of our backlog or adverse changes in the timing of 
receipt of revenues under contracts included in backlog;  failure to successfully integrate recently acquired companies or businesses into our operations or to 
realize any accretive or synergistic effects from such acquisitions; failure to successfully identify and execute future acquisitions; adverse changes in business 
conditions that may cause our investments in recorded goodwill to become impaired; non-compliance with, or adverse changes in, complex U.S. government 
procurement laws, regulations or processes;  failure to maintain strong relationships with other contractors; adverse results of U.S. government audits or other 
investigations of our government contracts; disruption of our business or damage to our reputation resulting from security breaches in customer systems, 
internal systems or service failures (including as a result of cyber or other security threats) or employee or subcontractor misconduct; and adverse changes 
in our financing arrangements, such as increases in interest rates and restrictions imposed by our outstanding indebtedness, including the ability to meet 
financial covenants, or inability to obtain new or additional financing. These and other risk factors are more fully discussed in the section entitled “Risks Factors” 
in ManTech’s Annual Report on Form 10-K previously filed with the Securities and Exchange Commission on Feb. 21, 2014, Item 1A of Part II of our Quarterly 
Reports on Form 10-Q, and, from time to time, in ManTech’s other filings with the Securities and Exchange Commission.

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 of the forward-looking statements made herein, whether as a result of new information, subsequent events or circumstances, 
changes in expectations or otherwise.
