A Message from 
George J. Pedersen

In 2018, ManTech marked its 50th 
year in business, a remarkable feat 
that very few companies achieve. 
We celebrated this special year in the 
way that customers, employees and 
shareholders have come to expect 
throughout our history, by delivering
exceptional performance based on our 
dedication to supporting the customer 
mission, and safeguarding national 
and homeland security. 

At ManTech, surpassing expectations 
is a tradition our people will continue
to advance, setting the standard 
for excellence in the government 
services contracting industry in the
years ahead. I am proud to lead this 
outstanding team as ManTech enters 
the next 50 years.

George J. Pedersen
Executive Chairman and 
Chairman of the Board

Bringing Digital to the Mission

Bringing Digital to the Mission
Driving Performance at the Tactical Edge

TO OUR SHAREHOLDERS:

In 2018 ManTech delivered strong results on revenue, operating income, 
profit and EPS. We experienced significant growth with multiple contract
awards, more than 60 percent of it for new business.

The key drivers of ManTech’s ongoing success are our focus on the 
customer mission and our dedicated workforce. Our customers in
the defense, intelligence and federal civilian markets continue to
trust ManTech to deliver leading-edge solutions in cyber, cloud and 
emerging technologies and to provide full operational readiness of these
technologies as they are fielded. Our mission-focused culture attracts 
outstanding talent who work as a team Bringing Digital to the Mission for 
customers, and fueling continuous improvement of outcomes for every 
mission. As a result, ManTech has grown to become a company with
nearly $2.0 billion in revenue.

2018 RESULTS

In 2018, ManTech’s revenue rose 14 percent over the prior year to $1.96
billion, our third consecutive year of organic revenue growth. We reported 
operating income of $113 million, an operating margin of 5.8 percent, and
net income of $82 million. Diluted earnings per share was $2.06. Free
cash flow for the year was $93 million, and the company had $5.3 million
in cash and cash equivalents and $7.5 million in outstanding borrowings
on its $500 million revolving-credit facility.

Total contract awards reached $3.4 billion, driving a strong book-to-bill
ratio of 1.8x and demonstrating strong market demand for ManTech’s
expertise in cyber and other core disciplines. Top awards included: 

• A $959 million managed services contract to provide secured

enterprise IT solutions for a Department of Defense agency. Over 
the course of this 10-year award, ManTech will work to strengthen 
and secure infrastructure, networks and end points for this agency’s 
users worldwide.

• A $669 million award from the Department of Homeland Security
to provide Continuous Diagnostics and Mitigation (CDM), a vital
cybersecurity platform, for multiple federal civilian agencies. Under 
this six-year award for CDM DEFEND (Dynamic and Evolving Federal
Enterprise Network Defense), ManTech will strengthen multiple
agencies’ cybersecurity posture and improve their ability to rapidly
respond to cyberattacks.

2018 Annual Report

• $387 million in extensions and awards by the U.S. 
Air Force for full-spectrum security services.

As always, ManTech demonstrated our commitment
to ensuring operational readiness for America’s armed
forces. In May, we held the grand opening of our new 
facilities in Charleston, South Carolina to maintain and
repair U.S. Army mine-resistant ambush protected 
(MRAP) vehicles. We expanded our presence at 

NSWC-Crane in Indiana to augment support for 
advanced future warfighting capabilities for U.S. Navy
aircraft. 

In the fifth domain of cyber warfare, the U.S. Army 
selected ManTech to lead the pilot program for Army’s
Persistent Cyber Training Enterprise (PCTE) program,
training America’s next generation of cyber warriors.

A CULTURE OF INNOVATION

Looking ahead, we expect proposal activity in 2019
to remain robust. Leadership in technology innovation 
will continue to play a major role in advancing our 
business objectives.

In June, we named Matt Tait as the new President

clients’ future technology requirements and to ensure
interoperability.  

These initiatives ensure continual advancement and 
interoperability of best-in-class solutions for our 
customers, drive ManTech’s financial performance 
in the most exciting areas of today’s fast-paced 
technology market, and attract talented employees.
Monster.com for the third consecutive year named 
ManTech the #1 Company for Veterans, who
constitute nearly 50 percent of ManTech employees.

OUTLOOK

When ManTech talks about Bringing Digital to the 
Mission, we mean here and now. In 2019 we will
build upon our successful portfolio of technology 
capabilities through targeted investments in high-
end solutions that directly address and resolve the 
toughest challenges of our customers.

Financial Performance

Bringing Digital to the Mission

Full-spectrum cyber will continue to be a dominant 
focus as we apply ManTech’s proven knowledge 
of offensive cyber to building military-grade cyber 
defenses, and support our government’s “defend 
forward” doctrine of combating cyberattacks at the 
source. We will speed performance of cybersecurity 
solutions through a targeted, and pragmatic 
application of automation, including machine
learning and neural networks, and pursue the same 
disciplined approach to advancing our capabilities in 
aligned areas including analytics, IT modernization 
and systems engineering.

Most importantly, ManTech will remain a company
recognized for its outstanding people dedicated to 
the customer mission. This principle has been the 
mainstay of ManTech’s culture for half a century and 
will never change.

whether in the classroom, in virtualized environments, or at customer locations in the U.S. and around the world. 

Supply Chain Management and Logistics

We provide supply chain management and logistics services involving the use of sophisticated systems that secure the entire 
supply chain, from supplies to data.  Our comprehensive set of integrated logistics and supply chain management services include 
supply  chain  management  support  (such  as  warehousing,  logistics  management,  shipping/receiving  and  global  property 
management),  maintenance  and  reset  of  ground  vehicles  and  electronics,  business  process  outsourcing,  transportation  using 
contracted and government provided services and other field services support (including fielding, training and operations support).  
Our tools and systems can predict requirements and provide secure, real-time tracking analysis and reporting data to meet our 
customers' needs.  We have overseen some of the most important mission-critical logistics and supply chain management efforts 
for the U.S. government and have provided a full range of logistics and maintenance support across the globe.

Our Employees

Our customer's success is the end result of the hard work of our talented and dedicated employees.  At year end, our workforce 
consisted of approximately 7,800 employees, 69% of whom hold security clearances and approximately 47% of whom are veterans.  

Our Customers

We derive the vast majority of our revenues from U.S. government customers.  We have successful, long-standing relationships 
with these customers, having supported many of them for almost half a century.  For each of the last three years we have derived 
98% of our annual revenues from our U.S. government customers, with at least 73% of our revenues each such year from intelligence 

6

and defense customers. 

Backlog

At December 31, 2018, our backlog was $8.4 billion, of which $1.3 billion was funded backlog.  At December 31, 2017, our 
backlog was $7.1 billion, of which $1.4 billion was funded backlog.  We expect that approximately 23% of our total backlog will 
be recognized as revenue prior to December 31, 2019.

We define backlog as our estimate of the remaining future revenue from existing signed contracts, assuming the exercise of 
all options relating to such contracts and including executed task orders issued under Indefinite Quantity/Indefinite Delivery (ID/
IQ) contracts.  We also include an estimate of revenue for solutions that we believe we will be asked to provide in the future under 
the terms of ID/IQ contracts for which there are established patterns of revenues.

We define funded backlog as 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 over a much longer period 
of time.

A variety of circumstances or events may cause changes in the amount of our backlog and funded backlog, including the 
execution of new contracts, the extension of existing contracts, the non-renewal or completion of current contracts, 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.

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 protect our patents, marks, trade secrets and vital confidential information, our business 
does not depend on the existence or protection of such intellectual property.

Seasonality

Our business is not seasonal.  However, in order to avoid the loss of unexpended fiscal year funds it is not uncommon for 
U.S. government agencies to award extra tasks or complete other contract actions in the weeks before September 30, which is the 
end of the U.S. government's fiscal year (GFY).  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. 

Business Environment and Competitive Landscape

Our primary customer is the U.S. government, the largest consumer of services and solutions in the U.S.  In U.S. GFY 2018, 
the U.S. government obligated approximately $333 billion on contracted services, an 8% increase from the prior year.  Our principal 
focus is on the national security and defense of the U.S. homeland.  The DoD is the largest purchaser of services and solutions in 
the U.S. government and with the U.S. GFY 2020 budget request of $701 billion, it accounts for approximately 58% of the total 
discretionary budget.  The DoD has experienced five years of consecutive budget growth.  Additionally, Budget Control Act Caps 
(BCAC) were raised by $80 billion in U.S. GFY 2018 and $85 billion in U.S. GFY 2019 as a result of the two-year Bipartisan 
Budget Act of 2018.  The DoD appropriations for U.S. GFY 2018 and U.S. GFY 2019 resulted in 8% and 3%  growth year-over-
year, respectively.

We compete in a market shaped by customer requirements and federal budget priorities and constraints.  Our key competitors 
currently include divisions of large defense contractors, as well as a number of large and 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 we bid 
against these companies in other situations. 

The budget environment continued to improve and grow in 2018, following several years of budget constraints and uncertain 
funding levels.  Congressional actions have alleviated much of the potential impact of sequestration historically but BCAC remain 
longer term.   The majority of our customers are fully funded for the fiscal year, however a handful are currently operating under 
a Continuing Resolution as Congress works to finalize the details of a bipartisan budget comprise, which would provide visibility 
7

into funding and spending levels for the U.S. GFY 2020 and U.S. GFY 2021 substantially above the BCAC.  The improved budget 
clarity resulted in our customers making more award decisions and procuring services to meet mission needs on a more regular 
and  predictable  basis.    We  also  believe  that  our  customers'  use  of  lowest  price/technically  acceptable  procurements,  which 
contributed to pricing pressures and lower margins in prior years, has leveled off or been reduced by some customers.  Under the 
current Administration,  we  believe  the  defense  budget  outlook  has  improved  meaningfully  and  we  expect  defense  spending 
increases relative to prior years.

The Administration has cited significant global threats, readiness and force structure needs within the military, diplomatic, 
homeland and border security, and cyber aggressions by both state and non-state actors, as priorities in establishing federal policy 
and budgets.  Although the Administration's priorities will be subject to Congressional debate, we believe that the U.S. government's 
spending will remain robust in key areas that we are well positioned to serve, including national and homeland security programs, 
cyber security, sophisticated intelligence gathering and information sharing activities.

Risk Factors 

Set forth below are the risks that we believe are material to our investors.  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.  Any of the following risks could materially and adversely affect our 
business, financial condition, results of operations and prospects, as well as the actual outcome of matters as to which forward-
looking statements are made in this Annual Report.

The risks described below are not the only risks we face.  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. government for substantially all of our revenues.  If our relationships with the U.S. 
government are harmed, our business, future revenues and growth prospects could be adversely affected. 

We derive the vast majority of our revenues from our U.S. government customers.  We expect that U.S. government contracts 
will continue to be the primary source of our revenues for the foreseeable future.  For this reason, any issue that compromises our 
relationship with the U.S. government generally or any U.S. government agency that we serve could adversely and materially 
harm our business, prospects, financial condition or operating results.  Among the key factors in maintaining our relationships 
with U.S. government agencies are our performance on our contracts and task orders, the strength of our professional reputation, 
compliance with applicable laws and regulations, and the strength of our relationships with our customers and client personnel. 
To the extent our reputation or relationships with U.S. government agencies is impaired, our revenue and operating profits could 
materially decline. 

We may fail to attract and retain skilled and qualified employees with requisite specialized skill sets or security clearances, 
which could impair our ability to effectively serve our clients, require more subcontracting work than is optimal, and limit our 
growth prospects.

Our business depends in large part upon our ability to attract and retain sufficient numbers of employees who have advanced 
IT and technical services skills.  Often, these employees must also have some of the highest security clearances in the United 
States.  While the government is focused on this issue, and we are beginning to see some improvement in the process, security 
clearances may take 12-24 months to complete depending upon the level of clearance and demand levels for cleared professionals.  
Cleared  employees  are  in  great  demand,  and  we  compete  intensely  for  such  qualified  personnel  with  other  U.S.  government 
contractors, the U.S. government and private industry.  Such personnel may remain a limited resource for the foreseeable future.  
8

  
If we are unable to recruit and retain a sufficient number of qualified employees or fail to obtain their appropriate security clearances 
in a timely manner, our ability to maintain and grow our business and effectively serve our clients could be limited and our future 
revenues and results of operations could be materially and adversely impacted.  Furthermore, to the extent that we are unable to 
hire sufficient qualified employees to staff our contracts, we may be required to engage larger numbers of contracted personnel, 
which could reduce our profit margins.  Even if we are able to attract the requisite skilled employees, the intense competition for 
such  employees  may  result  in  attrition  in  our  employee  ranks,  requiring  us  to  expend  additional  resources  to  hire  and  train 
replacement personnel.  The loss of services of key personnel could impair our ability to perform required services under some 
of our contracts, which could result in the termination of such contracts and limit our ability to win new business. 

We derive most of our revenues from contracts awarded through competitive bidding processes, and our revenue and profitability 
may be adversely impacted if we fail to compete effectively in such processes, or if there are delays as a result of our competitors' 
protests of contract awards that we receive.  

We derive a significant portion of revenues from U.S. government contracts awarded through a competitive bidding process.  
We  do  not  anticipate  that  this  will  change  in  the  foreseeable  future.    Our  failure  to  compete  effectively  in  this  procurement 
environment would have a material adverse impact on our revenue and profitability.  The competitive bidding process involves 
risk and significant costs to businesses operating in this environment including: 

• 

• 

• 

the substantial cost and managerial time and effort spent to prepare bids and proposals for contracts that may not be 
awarded to us;

the  need  to  expend  resources  and  make  financial  commitments  (such  as  procuring  leased  premises)  and  bid  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 competitions, the loss of committed costs;

the expense and delays that may arise if our competitors protest or challenge contract awards made to us, and the 
risk that any such protest could result in the resubmission of bids on modified specifications, or in the termination, 
reduction or modification of the awarded contract; and

• 

the ability to accurately estimate the resources and costs structure required to service any contract we are awarded.

The current competitive environment has resulted in an increase in the number of bid protests from unsuccessful bidders on 
new program awards. It can take months to resolve protests by one or more of our competitors of contract awards we receive.  
Even where the protest does not result in us losing the awarded contract, the resulting delay in startup and funding of the work 
under such contracts may cause our actual results to differ materially and adversely from anticipated results.

If we are unable to win particular contracts that are awarded through the competitive bidding process, we may not be able to 
operate in the market for services that are provided under those contracts for the duration of those contracts, to the extent that there 
is no additional demand for such services.  Our inability to win new contract awards over an extended period of time would have 
a material adverse effect on our business and results of operations.  

U.S. government spending and mission priorities could change in a manner that adversely affects our future revenues and 
limits our growth prospects, or Congress may fail to approve budgets on a timely basis for the federal agencies we support 
which could delay procurement of our services and solutions and cause us to lose future revenues.

Our business depends upon continued U.S. government expenditures on intelligence, defense, homeland security, federal 
health IT and other programs that we support.  These expenditures have not remained constant over time, have been reduced in 
certain periods and have been affected by the U.S. government's efficiency and cost reduction efforts.  Additionally, in recent 
years, in the face of growing national debt and long-term fiscal challenges facing the nation, spending levels for U.S. government 
programs generally, and in particular the U.S. defense budget, have come under pressure.  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.    Notwithstanding  the  recent 
stabilization of base budgets and improved budget clarity, discretionary spending may remain constrained, affect future levels of 
expenditures (or timing of expenditures), place pressure on operating margins or result in a shift of expenditures to programs that 
9

we do not currently support.  Each of these changes in U.S. government spending could adversely impact our business and future 
results of operations.

We face aggressive competition from many competitors, which may adversely impact our profitability and growth prospects.

We operate in highly competitive markets and generally encounter intense competition to win contracts, which are usually 
subject to competitive bidding processes.  We may not be able to continue to win competitively awarded contracts at historic 
levels.  We compete with larger companies who may have greater financial resources than we have.  We also compete with smaller, 
more specialized companies that may be able to concentrate their resources into highly-skilled niche markets.  Our competitors 
may be able to provide our customers with different or greater capabilities or better contract terms than we can provide, including 
price,  technical  qualifications,  past  contract  experience,  geographic  presence  and  the  availability  of  qualified  professional 
personnel.  If we lose business to our competitors or are forced to reduce our prices, our revenue and operating profits could 
decline. 

We may not realize the full value of our backlog, which may result in lower revenues than anticipated. 

As of December 31, 2018, our backlog was $8.4 billion, of which $1.3 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, our estimates of future 
revenues are inexact and the receipt of these revenues are subject to various contingencies, many of which are beyond our control.  

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.  The actual accrual and recognition of revenues on programs that are included in backlog 
may never occur or may change for a number of reasons, including if a program is changed, delayed or cancelled; if the funding 
or scope of a contract is reduced, modified, delayed or terminated early (including as a result of a lack of appropriated funds or 
as a result of cost cutting initiatives); if an option that we have assumed would be exercised is not exercised; or if our estimates 
regarding the amount of services that we will provide under contracts prove to be inaccurate.  Our unfunded backlog, in particular, 
contains management's estimate of amounts expected to be realized on unfunded contract work, and this work may never be 
realized as revenues.  In addition, there can be no assurance that our backlog will result in actual revenue during any particular 
fiscal period, as the timing of the receipt of revenue under contracts included in backlog is subject to various contingencies, many 
of which are beyond our control.

If we fail to realize as revenues amounts included in our backlog, our future revenues and growth prospects may be adversely 

affected. 

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 U.S. 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

Total

Year Ended 
December 31,

2018

2017

10%

100%

66%

21%

13%

100%

68%

19%

13%

100%

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.

10

•  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 U.S. 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  U.S. 
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.  With respect to our fixed-
priced managed services business, if the cost vary from our assumptions and projections it could cause profit margins 
on that work to fluctuate. 

•  Under time-and-materials contracts, we are reimbursed for labor at negotiated hourly billing rates and for certain 
expenses.  We assume financial risk on time-and-materials 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.  

The U.S. government may prefer minority-owned, small and small disadvantaged businesses; therefore, we may have fewer 
opportunities to bid for.

As  a  result  of  the  Small  Business Administration  set-aside  program,  the  U.S.  government  may  decide  to  restrict  certain 
procurements only to bidders that qualify as minority-owned, small or small disadvantaged businesses.  As a result, we would not 
be eligible to perform as a prime contractor on those programs and would be restricted to a maximum of 49% of the work as a 
subcontractor on those programs.  An increase in the amount of procurements under the Small Business Administration set-aside 
program may impact our ability to bid on new procurements as a prime contractor or restrict our ability to recompete on incumbent 
work that is placed in the set-aside program.  An increase in set-aside work, even where we are successful in teaming with a small 
business, could result in less revenue and profit for us.

U.S. 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. 

U.S. 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 U.S. 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 is deemed to 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 

11

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. 

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 services to our customers, which as a leading provider of cyber security services 
to our customers could damage our reputation and have a material adverse effect on our business and results of operations.

We create, implement and maintain IT 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.  We are subject to systems or service failures (both our own failures and the failures of third-party 
service providers), which may be caused by natural disasters, power shortages or terrorist attacks, as well as from continuous 
exposure to cyber and other security threats, including computer viruses, attacks by computer hackers and physical break-ins.  We 
also face a heightened risk of a security breach or disruption due to our custody of classified and other sensitive information.  Many 
government contractors have already been targeted and these types of attacks are likely to occur in the future.  Attacks on our 
network or other systems could result in the loss of customer or proprietary data, interruptions or delays in our customers' business, 
and damage to our reputation, which could have a material adverse effect on our business and results of operations.  In addition, 
the failure or disruption of our systems, communications or utilities could result in the interruption or suspension of 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, if we are successfully attacked by cyber or 

other security threats, or if we 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 rely on the creation and maintenance of secure IT systems;

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  laws,  including  laws  governing  protection  of  
personal information.

In addition to costs related to contract performance or required corrective action, these failures may result in increased costs 
or loss of revenues if our customers terminate or reduce the scope of our contracts, or do not renew our contracts as a result of 
such failures. 

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.  A successful large 
12

claim against us could seriously harm our business, and any claim, whether successful or not, may 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  the  systems  we  develop,  install  and  maintain  involve  managing  and  protecting 
information involved in intelligence, national security and other classified or sensitive customer functions.  Losses from a security 
breach in one of these systems could cause serious harm to our business, damage our reputation and impact our eligibility for 
further work on critical systems for our current customers or for other U.S. government customers generally.  Losses could also 
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 could materially reduce our revenues.

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.  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 have difficulty retaining an acquired company's key employees, customers or contracts (particularly with 

respect to awards not made on a full and open basis);

•  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 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.

If we fail to comply with complex laws and procurement 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 U.S. government 
contracts.  These laws and regulations affect how we conduct business with our U.S. 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  and  the  Defense  Federal  Acquisition  Regulation  Supplement,  which 

comprehensively regulate the formation, administration and performance of U.S. government contracts; 

•  Truthful Cost or Pricing Data, 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 U.S. 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 

suspension or debarment from contracting with the U.S. government. 

13

Our contracting agency customers periodically review our compliance with laws and procurement regulations, as well as our 
performance under the terms of our U.S. 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 the termination of contracts, 
forfeiture of profits, the triggering of price reduction clauses, suspension of payments, fines and the suspension or debarment from 
doing business with federal government agencies.

Additionally, the False Claims Act provides for substantial damages and penalties where, for example, a contractor presents 
a false or fraudulent claim to the government for payment or approval.  Actions under the False Claims Act may be brought by 
the government or by individuals 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. 

Unfavorable U.S. 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),  Defense  Contract  Management Agency  (DCMA)  and  other  government 
agencies  routinely  audit  and  investigate  government  contracts  and  contractor  systems.    These  agencies  review  our  contract 
performance, cost structure and compliance with applicable laws, regulations and standards.  The DCAA and DCMA also review 
the  adequacy  of,  and  compliance  with,  internal  control  systems  and  policies,  including  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.  If any of our internal control systems or policies is found to be non-
compliant or inadequate, payments may be withheld or suspended under our contracts, or we may be subject to increased government 
scrutiny and approval requirements that could delay or adversely affect our ability to invoice and receive timely payment for 
services we perform on our contracts.  Adverse findings by DCAA or DCMA may also impair our ability to compete for and win 
new contracts with the U.S. government.  As a result, a DCAA or DCMA audit could materially affect our competitive position 
and result in a substantial adjustment to our revenues and adversely affect our profitability. 

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;

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

with U.S. requirements;

•  Customary  business  practices  and  other  factors  in  foreign  countries,  including  requirements  to  provide  up-front 
performance bonds (guaranteed by a letter of credit from our lender), may involve uncertainties not associated with 
the business of contracting with the U.S. government, including potential difficulties in collecting receivables and 
fewer available remedies to the contractor in the event of contract disputes or contract terminations;

• 

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 international and U.S. laws, including the Foreign Corrupt Practices Act and U.S. 

export control regulations.

These regulatory, geopolitical and other risks could have an adverse effect on our business in the future, particularly if we 

increase the amount of work that we plan to perform internationally.

14

 
Our business operations in foreign countries 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, adversely affect our results of operations and financial condition.

We provide services in foreign countries that may be experiencing political unrest, war or terrorism.  In these deployments, 
we are exposed to the risk of liabilities arising from accidents or incidents involving our employees or third parties.  Accidents or 
incidents could involve significant injury or other claims by employees or third parties.  We may encounter unexpected costs in 
connection with additional risks inherent to such deployments, 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 foreign operations.  Substantial claims 
in excess of our insurance coverage could adversely affect our operating performance and may result in additional expenses and 
possible loss of revenues.  Even fully insured claims may result in negative publicity that could adversely affect our reputation 
among our customers and the public, which could cause us to lose existing and future contracts, make it more difficult to compete 
effectively for future contracts, and result in additional expenses and possible loss of revenues.

Goodwill represents a significant asset on our balance sheet, and changes in future business conditions could cause these 
investments to become impaired, requiring substantial write-downs that would reduce our operating income.

As of December 31, 2018, our goodwill was $1.1 billion.  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. 

Our failure to maintain strong relationships with other contractors, or the failure of other contractors with whom we have 
entered into a subcontract or prime contract relationship to meet their contractual obligations to us or our clients, could have 
a material adverse effect on our business and results of operations.

As a prime contractor, we often rely on other companies to perform some of the work under a contract, and we expect to 
continue to depend on relationships with other contractors for portions of our delivery of services and revenue for the foreseeable 
future.  There is a risk that we may have disputes with our subcontractors regarding a variety of issues, including the quality and 
timeliness of work performed by the subcontractor, client concerns about the subcontractor, our failure to extend existing task 
orders or issue new task orders under a subcontract, or our hiring of the subcontractor’s personnel.  In addition, if any of our 
subcontractors fail to deliver supplies or perform services on a timely basis, our ability to fulfill our obligations as a prime contractor 
may be jeopardized and could result in our customer terminating our prime contract for default.  A termination for default could 
expose us to liability and have an adverse effect on our ability to compete for future contracts and orders.

We derive a portion of our revenues from contracts where we are a subcontractor to other companies that have contracted 
directly with the end customer.  As a subcontractor, we often lack control over whether the terms of the prime contract are being 
satisfied.  Poor performance on such contracts could impact our reputation, even if we perform as required.  In addition, as a 
subcontractor, we may be unable to collect payments owed to us by the prime contractor, even if we have performed our obligations, 
if the prime contractor has failed to satisfy the terms of the prime contract. 

We occasionally enter into joint ventures with other companies to jointly bid on and perform a particular project.  The success 
of our joint ventures typically depends on the satisfactory performance of contractual obligations by our joint venture partners.  
If our partners do not meet their obligations, our joint ventures may be unable to adequately perform and deliver the 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, and could also adversely affect our reputation.

15

Covenants in the instruments governing our revolving credit facility 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 million revolving credit facility.  The maturity date for the credit agreement is August 17, 2022.  
The credit agreement requires us to comply with specified financial covenants, including the maintenance of certain consolidated 
total leverage ratios and a certain fixed charge coverage ratio, and contains negative covenants that, among other things, may limit 
or impose restrictions on the ability of us to incur additional indebtedness, make investments, make acquisitions and undertake 
certain other actions.  Additionally, an event of default under the credit agreement could result in our creditors exercising rights 
that could have a material adverse effect on our business.

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.  In addition to the risk factors 
already identified in this section of our Form 10-K, a number of additional factors could cause our revenues, cash flows and 
operating results to vary from quarter-to-quarter, including: 

• 

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

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

•  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, such as acquisitions, divestitures, spin-offs and joint ventures; 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 level of services we provide under existing contracts and the number of contracts that are commenced, completed 
or terminated during any quarter.  Depending on the nature of the contract, we may incur significant operating expenses during 
the start-up and early stages of large contracts, and in such cases we typically do not receive corresponding payments from the 
customer 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.

We have maintained a regular cash dividend program since 2011.  We anticipate continuing to pay quarterly dividends during 
2019.  However, any future payment of dividends, including the timing and amount of any such dividends, is at the discretion of 
our Board of Directors and may depend upon our earnings, liquidity, financial condition, alternate capital deployment opportunities 
or any other factors that our Board of Directors considers relevant.  A change in our regular cash dividend program could have an 
adverse effect on the market price of our common stock.

Mr. Pedersen, our Executive Chairman and Chairman of the Board, effectively controls us, and his interests may not be aligned 
with those of other stockholders. 

As of December 31, 2018, Mr. Pedersen owned approximately 33% 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 13,188,045 shares of Class B common stock as of December 31, 2018; thus 
he controlled approximately 83% of the combined voting power of our stock as of December 31, 2018.  Accordingly, Mr. Pedersen 
controls the vote on substantially 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 
16

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 us, regardless of whether a premium is offered over then-current market prices.  Mr. Pedersen will be able to 
cause a change of control of us.  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 adversely affect 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 us, 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 Securities and Exchange Commission 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 that are material 
to our operations.  Our facilities are leased in close proximity to our customers.  As of December 31, 2018, we leased 32 facilities 
throughout the metropolitan Washington, D.C. area and 24 facilities in other parts of the U.S., for approximately 1.6 million square 
feet.  We also have employees working at customer sites throughout the U.S. and in other countries.  Our leases expire between 
2019 and 2025. 

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. 

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 U.S. 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 
are  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  U.S. 
government or a particular agency or civil or criminal proceedings seeking penalties and/or fines.  Audits and investigations 
conducted by the U.S. 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.

Item 5. 

Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Market Information 

Our Class A common stock has been quoted on the Nasdaq Stock Market under the symbol “MANT” since our initial public 
offering on February 7, 2002.  There is no established public market for our Class B common stock.  As of February 20, 2019, 
there were 61 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 2018 and 2017, we declared and paid quarterly dividends, each in the amount of $0.25 and $0.21 per 
share, respectively, on all issued and outstanding shares of common stock.  For 2019, we anticipate we will continue paying 
quarterly dividends, and on February 19, 2019, the Board of Directors declared a quarterly cash dividend in the amount of $0.27
per share; however any future dividends declared will be at the discretion of our Board of Directors and will depend, among other 
factors, upon our earnings, liquidity, financial condition, alternate capital allocation opportunities or any other factors our Board 
of Directors deems relevant. 

Recent Sales of Unregistered Securities 

We did not issue or sell any securities in fiscal year 2018 that were not registered under the Securities Act of 1933. 

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

We did not purchase equity securities during the year ended December 31, 2018.

(1) The Tax Cuts and Jobs Act, enacted on December 22, 2017, reduces the U.S. corporate tax rate from 35% to 21%
beginning in 2018.  Due to the enactment of the Tax Cuts and Jobs Act, our income tax expense was reduced by $50.6 million
for the year ended December 31, 2017 from the re-measurement of our existing deferred tax assets and liabilities.

(2) On April 15, 2014, we paid the redemption price plus accrued and unpaid interest on our 7.25% senior unsecured notes
issued on April 13, 2010 for $200.0 million.  As a result of the redemption of our 7.25% senior unsecured notes, we recorded
a loss on the extinguishment of debt for $10.1 million as non-operating income.

(3) On January 1, 2018, we adopted Accounting Standards Codification (ASC) 606, Revenue from Contracts with Customers, 
using the modified retrospective method applied to those contracts that were not substantially complete as of January 1, 2018.  
Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts were 
adjusted and continue to be reported in accordance with ASC 605, Revenue Recognition.

(4) Over the past five years, we completed 7 acquisitions.  In aggregate, these acquisitions have added $336.9 million in
goodwill.  For additional information on our recent acquisitions, see Note 4 "Acquisitions" to our consolidated financial
statements in Item 8 "Financial Statements and Supplementary Data."

Item 7. 

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 Supplementary Data."  This 
discussion contains forward-looking statements that involve risks and uncertainties.  For a description of these forward-looking 
statements, refer to Part I “Cautionary Note Regarding 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 those discussed elsewhere in this Annual Report.

Overview 

We provide mission-focused technology solutions and services for U.S. defense, intelligence community and federal civilian 
agencies.  Now in our 50th year, we excel in full-spectrum cyber, data collection & analytics, enterprise IT, systems engineering 
and software application development solutions that support national and homeland security. 

21

With substantially all of our revenues being derived from contacts with the U.S. Government, or through prime contractors 
supporting the U.S. government, our results and outlook are significantly impacted by U.S. Government policy and spending.  
Federal spending, particularly the DoD, has experienced five years of consecutive growth.  The DoD appropriations for U.S. GFY 
2018 and U.S. GFY 2019 grew 8% and 3% year-over-year, respectively.  Additionally, spending for IT and cyber contracts increased 
across the federal government at rates faster than top-line budget growth.  

For U.S. GFY 2019, the President signed into law appropriations on September 28, 2018 funding approximately 75% of the 
U.S.  government,  including  the  Department  of  Defense,  the  Intelligence  Community,  Department  of  Veterans  Affairs  and 
Department of Health and Human Services among other select agencies.  However, a number of federal civilian agencies, including 
the Departments of Homeland Security, Justice and State, remained funded under a Continuing Resolution (CR) through early 
December 2018.  In December 2018, Congress and the President failed to reach an agreement to fund those departments that were 
operating under the CR, which forced a shutdown of all activities deemed nonessential.  A majority of our contract work for these 
agencies had been deemed essential.  Exiting 2018, and through the shutdown ended January 25, 2019, approximately 2% of our 
workforce was impacted. 

The 2018 mid-term election established a divided Congress.  The composition of Congress may limit major shifts in policy 
and could increase the likelihood that we will enter U.S. GFY 2020 under CR.  We expect future appropriations to be debated with 
the consideration of policy priorities, national budget deficits, debt ceilings, the Budget Control Act and an increasing global threat 
environment. 

Our industry remains competitive on price.  We will continually evaluate and adjust our levels of indirect spending to stay in 
line  with  the  expected  business  opportunities  to  ensure  our  cost  structure  remains  competitive.    Our  industry  also  remains 
competitive in attracting and retaining employees with the necessary skills and security clearances to perform the services we 
have promised in our contracts.  We will continue to pursue acquisitions that broaden our domain expertise and service offerings 
and/or establish relationships with new customers.  Since going public in 2002, we have acquired and integrated 28 businesses 
into our operations. 

Revenues

Substantially all of our revenues are derived from services and solutions provided to the U.S. government or to prime contractors 
supporting the U.S. government, including services provided by our employees and our subcontractors, and solutions that include 
third-party hardware and software that we purchase and integrate as a part of our overall solutions.  Customer 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.

Our prime contractor revenues as a percentage of our total revenues were 89%, 88% and 88%, respectively, for the three years 

ended December 31, 2018, 2017 and 2016. 

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

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 based on factors such as our prior award experience and communications 
with the customer regarding performance.    

Fixed-price contracts - We perform specific tasks for a fixed price.  Fixed-price contracts may include either a product delivery 

22

or specific service performance over a defined period.  Revenues on fixed-price contracts that provide for us to render services 
throughout a period are recognized under a time based model or as earned based on a measure of progress using cost incurred, 
direct  labor  or  direct  labor  hours.    For  fixed-price  contracts  that  provide  for  the  delivery  of  a  specific  product,  revenues  are 
recognized either over time as costs are incurred or at a point in time based on delivery.  

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-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 under a right 
to invoice model. 

For additional information on revenue recognition methods, including methods used prior to the adoption of ASC 606 on 

January 1, 2018, see Note 2 "Summary of Significant Accounting Policies" to our consolidated financial statements in Item 8.

Our contract mix varies from year-to-year due to numerous factors, including our business strategies and U.S. government 
procurement objectives.  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.  

Cost of Services 

Cost of services primarily includes direct costs incurred to provide services and solutions to our 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.  
As we earn higher profits on our own labor services, we expect the ratio of cost of services as a percentage 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 increases relative to our own labor services, we expect the ratio of cost of services 
as a percentage of revenues to increase.  

The proportion that cost 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-and-materials contracts than cost-reimbursable contracts.  Fixed-
price contracts generally offer higher profit margin opportunities but can involve greater financial risk because we bear the impact 
of cost overruns in return for the full benefit of any cost savings.

23

 
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 
expenses 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 debt 

and deferred financing charges. 

Interest Income

Interest income is primarily from cash on hand and late invoice payments by the government.

Revenues

The primary driver of our increase in revenues relates to revenues from new contract awards, growth on existing contracts 
and our acquisition, which were offset by contracts and tasks that ended and reduced scope of work on some contracts.  We expect 
revenues to increase in 2019 due to new contract awards and growth on existing programs.

Cost of services 

The increase in cost of services was primarily due to increases in revenues.  As a percentage of revenues, direct labor costs 
decreased to 47% compared to 48% for the years ended December 31, 2018 and 2017, respectively.  As a percentage of revenues, 
other direct costs, which include subcontractors and third party equipment and materials used in the performance of our contracts, 
increased to 39% for the year ended December 31, 2018, compared to 37% for the same period in 2017.  In 2019, we expect cost 
of services as a percentage of revenues to remain relatively stable as compared to 2018.

General and administrative expenses 

The increase in general and administrative expenses was primarily due to staffing increases to support the growth of our 
business,  infrastructure  improvements  and  amortization  of  acquisition  intangibles.   As  a  percentage  of  revenues,  general  and 
administrative expenses decreased for the year ended December 31, 2018 as compared to the same period in 2017.  In 2019, we 
expect general and administrative expenses as a percentage of revenues to decrease slightly as compared to 2018. 

(Provision) benefit for income taxes

Our effective tax rate is affected by recurring items, such as the relative amount of income we earn in various taxing jurisdictions 
and their tax rates.  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 rate was 26% and (17)% for the years ended December 31, 2018 and 2017, respectively.  The Tax Cuts 
and Jobs Act, enacted on December 22, 2017, reduced the U.S. corporate tax rate from 35% to 21% beginning in 2018.  Due to 
the enactment of the Tax Cuts and Jobs Act, our income tax expense was reduced by $50.6 million for the year ended December 31, 
2017 from a re-measurement of our existing deferred tax assets and liabilities.  For additional information concerning the re-
measurement adjustment see Note 12 "Income Taxes" to our consolidated financial statements in Item 8.  In 2017, our effective 
tax rate was also favorably impacted by tax benefits from the exercise and vesting stock based awards and the performance of our 
deferred compensation plan.  In 2018, our effective tax rate was adversely impacted by the non-deductibility of excess executive 
compensation and by the performance of our deferred compensation plan.

The primary driver of our increase in revenues relates to revenues from new contract awards, growth on existing contracts 

and our acquisitions, which were offset by contracts and tasks that ended and reduced scope of work on some contracts. 

Cost of services 

The increase in cost of services was primarily due to increases in revenues.  As a percentage of revenues, direct labor costs 
remained stable at 48% for both years ended December 31, 2017 and 2016.  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 to 37% for 
the year ended December 31, 2017, compared to 38% for the same period in 2016. 

General and administrative expenses 

The  increase  in  general  and  administrative  expenses  was  primarily  due  to  an  increase  in  incentive  compensation  from 
performance based plans, staffing increases to support the growth of our business, amortization of acquisition intangibles and bid 
and proposal spending.  As a percentage of revenues, general and administrative expenses increased for the year ended December 31, 
2017 as compared to the same period in 2016, due to the mentioned above spending increases. 

Interest expense

The  increase  in  interest  expense  was  primarily  due  to  increased  borrowings  on  our  revolving  credit  facility  to  fund  the 
acquisition of InfoZen LLC (InfoZen).  For additional information on the acquisition of InfoZen see Note 4 "Acquisitions" to our 
consolidated financial statements in Item 8. 

26

Benefit (provision) for income taxes

Our effective tax rate is affected by recurring items, such as the relative amount of income we earn in various taxing jurisdictions 
and their tax rates.  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 rate was (17)% and 37% for the years ended December 31, 2017 and 2016, respectively.  The Tax Cuts 
and Jobs Act, enacted on December 22, 2017, reduced the U.S. corporate tax rate from 35% to 21% beginning in 2018.  Due to 
the enactment of the Tax Cuts and Jobs Act, our income tax expense was reduced by $50.6 million for the year ended December 31, 
2017 from a re-measurement of our existing deferred tax assets and liabilities.  For additional information concerning the re-
measurement adjustment see Note 12 "Income Taxes" to our consolidated financial statements in Item 8.  Our effective tax rate 
was also favorably impacted by tax benefits from the stock based compensation and deferred compensation plans.

Backlog 

For the years ended December 31, 2018, 2017 and 2016 our backlog was $8.4 billion, $7.1 billion and $4.9 billion, respectively, 
of which $1.3 billion, $1.4 billion and $1.0 billion, respectively, was funded backlog.  The increase in our backlog is due to our 
receipt of new contract awards.  The current trend is that contracts are awarded for a longer term, which increases the time over 
which backlog will be recognized as revenue.  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, 2018, our cash and cash equivalents balance was $5.3 million.  There were $7.5 million in outstanding 
borrowings under our revolving credit facility at December 31, 2018.  At December 31, 2018, we were contingently liable under 
letters of credit totaling $9.6 million, which reduced our ability to borrow under our revolving credit facility by that amount.  The 
maximum available borrowings under our revolving credit facility at December 31, 2018 were $482.9 million.

Generally, cash provided by operating activities is adequate to fund our operations, including payments under our regular 
cash dividend program.  Due to short-term 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) were 73 and 61 for the quarters ended December 31, 
2018 and 2017, respectively.  For the years ended December 31, 2018, 2017 and 2016, our net cash flows from operating activities 
were $93.4 million, $153.0 million and $95.8 million, respectively.  The decrease in net cash flows from operating activities during 
the year ended December 31, 2018 when compared to the same period in 2017 was primarily due to an increase in accounts 
receivable related to the timing of collections, with some delays in payments due to the government shutdown.  The increase in 
net cash flows from operating activities during the year ended December 31, 2017 compared to the same period in 2016 was 
primarily due to an increase in net income, timing of receivables, accounts payable and accrued salaries and other related expenses, 
offset by an increase in income tax payments.

Cash Used in Investing Activities

Our cash used in investing activities consists primarily of business combinations, purchases of property and equipment and 
investments in capitalized software for internal use.  For the years ended December 31, 2018, 2017 and 2016, our net cash used 
in investing activities were $44.3 million, $219.0 million and $72.1 million, respectively.  For the year ended December 31, 2018, 
our net cash used in investing activities were primarily due to capitalized expenditures.  For the year ended December 31, 2017, 
our net cash used in investing activities were primarily due to the acquisition of InfoZen and capital expenditures.  The increase 
in capital expenditures was primarily due to the upfront purchases of equipment and infrastructure in support of a managed IT 
services contract.  For the year ended December 31, 2016, our net cash used in investing activities were primarily due to the 
acquisition of Oceans Edge, Inc., Cyber Division and Edaptive Systems LLC as well as capital expenditures.

27

Cash Flows from (Used in) Financing Activities 

For the years ended December 31, 2018, 2017 and 2016, our net cash flows from (used in) financing activities were $(53.3) 
million, $10.6 million and $(10) thousand, respectively.  For the year ended December 31, 2018, our net cash used in financing 
activities were primarily due to repayment of borrowings and payments of dividends which were partially offset by proceeds from 
the exercise of stock options.  For the year ended December 31, 2017, our net cash flows from financing activities were primarily 
due to net borrowings under our revolving credit facility to fund the acquisition of InfoZen and proceeds from the exercise of 
stock options, which were partially offset by dividend payments and debt issuance costs related the amendment of our credit 
facility.  For the year ended December 31, 2016, our net cash used in financing activities were primarily due to dividends paid 
offset by the proceeds from the exercise of stock options and the excess tax benefits from the exercise of stock options.

Revolving Credit Facility 

We maintain a credit agreement with a syndicate of lenders led by Bank of America, N.A., as sole administrative agent.  The 
credit agreement provides for a $500 million revolving credit facility, with a $75 million letter of credit sublimit and a $30 million
swing line loan sublimit.  The credit agreement also includes an accordion feature that permits us to arrange with the lenders for 
the provision of additional commitments.  The maturity date is August 17, 2022. 

Borrowings under our credit agreement are collateralized by substantially all the assets of us and our Material Subsidiaries 
(as defined in the credit agreement) and bear interest at one of the following variable rates as selected by us 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 terms of the credit agreement permit prepayment and termination of the loan commitments at any time, subject to certain 
conditions.  The credit agreement requires us to comply with specified financial covenants, including the maintenance of certain 
consolidated leverage ratios and a certain consolidated 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 other actions.  As of, and during the fiscal years ending 
December 31, 2018 and 2017, we were in compliance with our financial covenants under the credit agreement.  

There  was  $7.5  million  and  $31.0  million  outstanding  on  our  revolving  credit  facility  at  December 31,  2018  and  2017, 

respectively. 

Capital Resources

We believe the capital resources available to us from cash on hand, our remaining 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.  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 borrowings of debt or issuance of equity.  

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, 2018 and 2017, we declared and paid quarterly dividends in the amount of $0.25 and 
$0.21 per share on both classes of common stock.  On February 19, 2019, we declared a quarterly cash dividend in the amount of 
$0.27 per share, to be paid in March 2019.  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 of Directors deems relevant. 

28

Off-Balance Sheet Arrangements 

In the ordinary course of business, we use letters of credit to satisfy certain contractual terms with our customers.  As of 
December 31, 2018, $9.6 million in letters of credit were issued but undrawn.  We have an outstanding performance bond in 
connection with a contract between ManTech MENA, LLC and Jadwalean International Operations and Management Company 
to fulfill technical support requirements for the Royal Saudi Air Force.  This performance bond is guaranteed by a letter of credit 
in the amount of $9.5 million.  We have off-balance sheet arrangements related to operating leases.  For a description of our 
operating leases, see Note 9 "Commitments and Contingencies" to our consolidated financial statements in Item 8 "Financial 
Statement and Supplementary Data."   

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 U.S. 
generally accepted accounting principles (GAAP).  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 account for a contract when both we and the customer approve and commit; our rights and those of the customer are 
identified, payment terms are identified; the contract has commercial substance; and collectability of consideration is probable.  
At contract inception, we identify the distinct goods or services promised in the contract, referred to as performance obligations. 
Then we determine the transaction price for the contract; the consideration to which we can expect in exchange for the promised 
goods or services in the contract.  The transaction price can be a fixed or variable amount.  It is common for our contracts to contain 
award fees, incentive fees or other provisions that can either increase or decrease the transaction price.  These variable amounts 
generally are awarded upon achievement of certain performance metrics, program milestones or cost targets and can be based 
upon customer discretion.  We estimate variable consideration at the most likely amount to which we expect to be entitled.  We 
include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue 
recognized will not occur when the uncertainty associated with the variable consideration is resolved.  Our estimates of variable 
consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment 
of our anticipated performance and historical, current and forecasted information that is reasonably available to us.  The transaction 
price is allocated to each distinct performance obligation using our best estimate of the standalone selling price for each distinct 
good or service promised in the contract.  The primary method used to estimate standalone selling price is the expected cost plus 
a margin approach, under which we forecast our expected costs of satisfying a performance obligation and then add an appropriate 
margin for that distinct good or service promised.  Revenue is recognized when, or as, the performance obligation is satisfied.

We recognize revenue over time when there is a continuous transfer of control to our customer.  For our U.S. government 
contracts, this continuous transfer of control to the customer is supported by clauses in the contract that allow the U.S. government 
to unilaterally terminate the contract for convenience, pay us for costs incurred plus a reasonable profit and take control of any 
work in process.  When control is transferred over time, revenue is recognized based on the extent of progress towards completion 
of the performance obligation.  Based on the nature of the products and services provided in the contract, we use our judgment to 
determine if an input measure or output measure best depicts the transfer of control over time.  For services contracts, we typically 
satisfy our performance obligations as services are rendered.  We typically use a cost-based input method to measure progress.  
Contract costs include labor, material and allocable indirect expenses.  Revenue is recognized proportionally as contract costs are 
incurred plus estimated fees.  For time-and-material contracts, we bill the customer per labor hour and per material, and revenue 
is recognized in the amount invoiced since the amount corresponds directly to the value of our performance to date.  For stand-
ready service contracts, a time-elapsed output method is used to measure progress, and revenue is recognized straight-line over 
the term of the contract.  If a contract does not meet the criteria for recognizing revenue over time, we recognize revenue at a point 
in time.  Revenue is recognized at the point in time when control of the good or service is transferred to our customer.  We consider 
control to transfer when we have a present right to payment and our customer has legal title.  Determining a measure of progress 
and when control transfers requires us to make judgments that affect the timing of when revenue is recognized.  Essentially, all 
of our contracts satisfy their performance obligations over time.

Contracts are often modified to account for changes in contract specifications and requirements.  Contract modifications 
impact performance obligations when the modification either creates new or changes the existing enforceable rights and obligations. 
29

The effect of a contract modification on the transaction price and our measure of progress for the performance obligation to which 
it relates is recognized as an adjustment to revenue and profit cumulatively.  Furthermore, a significant change in one or more 
estimates could affect the profitability of our contracts.  We recognize adjustments in estimated profit on contracts in the period 
identified.   The  impact  of  adjustments  in  contract  estimates  can  be  reflected  in  either  revenue  or  operating  expenses  on  our 
consolidated statement of income. 

We have an Estimate at Completion process in which management reviews the progress and execution of our performance 
obligations.  As part of this process, management reviews information including, but not limited to, any outstanding key contract 
matters, progress towards completion and the related program schedule, identified risks and opportunities and the related changes 
in estimates of revenue and costs.  The risks and opportunities include management’s judgment about the ability and cost to achieve 
the contract milestones and other technical contract requirements.  Management must make assumptions and estimates regarding 
labor productivity and availability, the complexity of the work to be performed, the availability of materials, the length of time to 
complete the performance obligation, execution by our subcontractors, the availability and timing of funding from our customer 
and overhead cost rates, among other variables.  A significant change in one or more of these estimates could affect the profitability 
of our contracts. 

Results for periods prior to January 1, 2018 were reported in accordance with ASC 605.  Revenue for cost-reimbursable 
contracts were recorded as reimbursable costs were incurred, including an estimated share of the applicable contractual fees earned.  
For performance-based fees under cost-reimbursable contracts, we recognized 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, 
revenue was recognized to the extent of billable rates times hours delivered plus materials and other reimbursable costs incurred.  
For long-term fixed-price contracts, revenue was recognized at a rate per unit as the units were delivered or by other methods to 
measure services provided.  Revenue from other long-term fixed-price contracts were recognized ratably over the contract period 
or by other appropriate methods to measure services provided.  Contract costs were 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, Revenue 
Recognition - Construction-Type and Production-Type Contracts, we applied the percentage of completion method.  Under the 
percentage of completion method, income was 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 required estimating the total revenue and total 
contract cost at completion of the contract.  These estimates were periodically reviewed and revisions were made as required using 
the cumulative catch-up method.  The impact on revenue and contract profit as a result of these revisions was included in the 
periods in which the revisions were made.  Estimated losses on contracts at completion were recognized when identified. In certain 
circumstances, revenue was recognized when contract amendments were not 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.  

In reviewing goodwill for impairment, we have the option to first assess qualitative factors to determine whether the existence 
of events or circumstances leads to a determination that it is more likely than not that the estimated fair value of a reporting unit 
is less than its carrying amount.  If we elect to perform a qualitative assessment and determine that an impairment is more likely 
than not, the entity is then required to perform the existing two-step quantitative impairment test (described below), otherwise no 
further analysis is required.  We also may elect not to perform the qualitative assessment and, instead, proceed directly to the two-
step quantitative impairment test.   

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 value (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 
30

 
 
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 us.  Valuation ratios, which relate market prices to selected financial statistics 
derived from comparable companies, are selected and applied to us 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 provides a reasonable basis for comparison to us.  Valuation ratios, which relate market 
prices to selected financial statistics derived from comparable companies, are selected and applied to us 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 our 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 as of October 31st of each calendar year.  The results of our annual goodwill 
impairment test as of October 31, 2018 indicated that the estimated fair value of each reporting unit substantially exceeded its 
respective carrying value.  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.

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.

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, 2018, we had $7.5 million outstanding 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 a $134 thousand dollar effect on 
our interest expense for the year ended December 31, 2018.

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 shareholders and the Board of Directors of ManTech International Corporation

Opinion on the Financial Statements

We  have  audited  the  accompanying  consolidated  balance  sheets  of  ManTech  International  Corporation  and  subsidiaries  (the 
"Company") as of December 31, 2018 and 2017, the related consolidated statements of income, comprehensive income, changes 
in stockholders' equity, and cash flows, for each of the three years in the period ended December 31, 2018, and the related notes 
and the schedule listed in the Index at Item 15  (collectively referred to as the "financial statements"). In our opinion, the financial 
statements present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2017, and 
the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018, in conformity 
with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company's internal control over financial reporting as of December 31, 2018, based on criteria established in 
Internal  Control  -  Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway 
Commission and our report dated February 22, 2019, expressed an unqualified opinion on the Company's internal control over 
financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on 
the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are 
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable 
rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error 
or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether 
due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, 
evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting 
principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial 
statements. We believe that our audits provide a reasonable basis for our opinion.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

Years Ended December 31, 2018, 2017 and 2016 

1.  Description of the Business 

ManTech International Corporation (depending on the circumstances, “ManTech” “Company” “we” “our” “ours” or “us”) 
provides mission-focused technology solutions and services for U.S. defense, intelligence community and federal civilian agencies.  
We  excel  in  full-spectrum  cyber,  data  collection  &  analytics,  enterprise  IT,  systems  engineering  and  software  application 
development solutions that support national and homeland security. 

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. 

Use of Accounting Estimates - We prepare our consolidated financial statements in conformity with U.S. GAAP, which 
requires 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 us.  Therefore, actual amounts could differ from these estimates. 

Revenue  Recognition  -  On  January  1,  2018,  we  adopted Accounting  Standards  Codification  (ASC)  606,  Revenue  from 
Contracts with Customers using the modified retrospective method applied to those contracts that were not substantially complete 
as of January 1, 2018.  ASC 606 outlines a five-step model whereby revenue is recognized as performance obligations within the 
contract  are  satisfied. ASC  606  also  requires  new,  expanded  disclosures  regarding  revenue  recognition.    We  recognized  the 
cumulative effect of adopting ASC 606 as an increase to the 2018 opening balance of retained earnings in the pretax amount of 
$0.8 million, with the impact primarily related to fixed-price contracts.  Results for reporting periods beginning after January 1, 
2018 are presented under ASC 606, while prior period amounts were not adjusted and continue to be reported in accordance with 
ASC 605, Revenue Recognition.  Revenue for the year ended December 31, 2018 increased $2.4 million as a result of applying 
ASC 606.

We account for a contract when: both we and the customer approve and commit; our rights and those of the customer are 
identified, payment terms are identified; the contract has commercial substance; and collectability of consideration is probable.  
At contract inception, we identify the distinct goods or services promised in the contract, referred to as performance obligations. 
Then we determine the transaction price for the contract; the consideration to which we can expect in exchange for the promised 
goods or services in the contract.  The transaction price can be a fixed or variable amount.  It is common for our contracts to contain 
award fees, incentive fees or other provisions that can either increase or decrease the transaction price.  These variable amounts 
generally are awarded upon achievement of certain performance metrics, program milestones or cost targets and can be based 
upon customer discretion.  We estimate variable consideration at the most likely amount to which we expect to be entitled.  We 
include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue 
recognized will not occur when the uncertainty associated with the variable consideration is resolved.  Our estimates of variable 
consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment 
of our anticipated performance and historical, current and forecasted information that is reasonably available to us.  The transaction 
price is allocated to each distinct performance obligation using our best estimate of the standalone selling price for each distinct 
good or service promised in the contract.  The primary method used to estimate standalone selling price is the expected cost plus 
a margin approach, under which we forecast our expected costs of satisfying a performance obligation and then add an appropriate 
margin for that distinct good or service promised.  Revenue is recognized when, or as, the performance obligation is satisfied.

We recognize revenue over time when there is a continuous transfer of control to our customer.  For our U.S. government 
contracts, this continuous transfer of control to the customer is supported by clauses in the contract that allow the U.S. government 
to unilaterally terminate the contract for convenience, pay us for costs incurred plus a reasonable profit and take control of any 
work in process.  When control is transferred over time, revenue is recognized based on the extent of progress towards completion 
of the performance obligation.  Based on the nature of the products and services provided in the contract, we use our judgment to 
determine if an input measure or output measure best depicts the transfer of control over time.  For services contracts, we typically 
satisfy our performance obligations as services are rendered.  We typically use a cost-based input method to measure progress.  
Contract costs include labor, material and allocable indirect expenses.  Revenue is recognized proportionally as contract costs are 
incurred plus estimated fees.  For time-and-material contracts, we bill the customer per labor hour and per material, and revenue

is recognized in the amount invoiced since the amount corresponds directly to the value of our performance to date.  For stand-
ready service contracts, a time-elapsed output method is used to measure progress, and revenue is recognized straight-line over 
the term of the contract.  If a contract does not meet the criteria for recognizing revenue over time, we recognize revenue at a point 
in time.  Revenue is recognized at the point in time when control of the good or service is transferred to our customer.  We consider 
control to transfer when we have a present right to payment and our customer has legal title.  Determining a measure of progress 
and when control transfers requires us to make judgments that affect the timing of when revenue is recognized.  Essentially, all 
of our contracts satisfy their performance obligations over time.

Contracts are often modified to account for changes in contract specifications and requirements.  Contract modifications 
impact performance obligations when the modification either creates new or changes the existing enforceable rights and obligations. 
The effect of a contract modification on the transaction price and our measure of progress for the performance obligation to which 
it relates is recognized as an adjustment to revenue and profit cumulatively.  Furthermore, a significant change in one or more 
estimates could affect the profitability of our contracts.  We recognize adjustments in estimated profit on contracts in the period 
identified.   The  impact  of  adjustments  in  contract  estimates  can  be  reflected  in  either  revenue  or  operating  expenses  on  our 
consolidated statement of income. 

We have an Estimate at Completion process in which management reviews the progress and execution of our performance 
obligations.  As part of this process, management reviews information including, but not limited to, any outstanding key contract 
matters, progress towards completion and the related program schedule, identified risks and opportunities and the related changes 
in estimates of revenue and costs.  The risks and opportunities include management’s judgment about the ability and cost to achieve 
the contract milestones and other technical contract requirements.  Management must make assumptions and estimates regarding 
labor productivity and availability, the complexity of the work to be performed, the availability of materials, the length of time to 
complete the performance obligation, execution by our subcontractors, the availability and timing of funding from our customer 
and overhead cost rates, among other variables.  A significant change in one or more of these estimates could affect the profitability 
of our contracts.  For the year ended December 31, 2018, the aggregate impact of adjustments in contract estimates increased our 
revenue by $9.8 million.  No adjustment on any one contract was material to our consolidated financial statements for the year 
ended December 31, 2018.

Results for prior periods were reported in accordance with ASC 605.  Revenue for cost-reimbursable contracts were recorded 
as reimbursable costs were incurred, including an estimated share of the applicable contractual fees earned.  For performance-
based fees under cost-reimbursable contracts, we recognized 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, revenue was recognized 
to the extent of billable rates times hours delivered plus materials and other reimbursable costs incurred.  For long-term fixed-
price contracts, revenue was recognized at a rate per unit as the units were delivered or by other methods to measure services 
provided.    Revenue  from  other  long-term  fixed-price  contracts  were  recognized  ratably  over  the  contract  period  or  by  other 
appropriate methods to measure services provided.  Contract costs were 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, Revenue Recognition 
- Construction-Type and Production-Type Contracts, we applied the percentage of completion method.  Under the percentage of 
completion method, income was 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 required estimating the total revenue and total contract cost at 
completion of the contract.  These estimates were periodically reviewed and revisions were made as required using the cumulative 
catch-up method.  The impact on revenue and contract profit as a result of these revisions were included in the periods in which 
the revisions were made.  Estimated losses on contracts at completion were recognized when identified. In certain circumstances, 
revenue was recognized when contract amendments were not finalized. 

Contract Assets  - Amounts  are  invoiced  as  work  progresses  in  accordance  with  agreed-upon  contractual  terms,  either  at 
periodic intervals or upon achievement of contractual milestones.  Generally, revenue recognition occurs before billing, resulting 
in contract assets.  These contract assets are referred to as unbilled receivables and are reported within receivables, net on our 
consolidated balance sheet.

Billed Receivables - Amounts billed and due from our customers are classified as billed receivables and are reported within 
receivables, net on the consolidated balance sheet.  The portion of the payments retained by the customer until final contract 
settlement is not considered a significant financing component because the intent is to protect the customer.

Contract Liabilities - We receive advances and milestone payments from our customers on selected contracts that exceed 
revenue earned to date, resulting in contract liabilities.  Contract liabilities typically are not considered a significant financing 
component because it is used to meet working capital demands that can be higher in the early stages of a contract and to protect 

42

 
us from the customer failing to adequately complete some or all of its obligations under the contract.  Contract liabilities are 
reported on our consolidated balance sheet on a net contract basis at the end of each reporting period.

Contract Costs - Contract costs include direct labor, direct materials, overhead and, when applicable, general and administrative 
expenses.  Incremental costs of obtaining a contract that we expect to recover are recognized as deferred contract costs and are 
amortized on a systematic basis that is consistent with the transfer to the customer of the goods or services.  Other incremental 
costs are expensed when incurred.  Costs of fulfilling a contract that relate directly to a contract or to an anticipated contract that 
can be specifically identified, generate or enhance resources that will be used in satisfying future performance obligations and are 
expected to be recovered are recognized as deferred contract costs and amortized on a systematic basis that is consistent with the 
transfer of the goods or services to the customer.  Other costs of fulfilling a contract (costs of wasted materials, labor or other 
resources to fulfill the contracts that were not reflected in the price of the contract and costs that relate to satisfied performance 
obligations in the contract) are expensed when incurred. 

Deferred Contract Costs - Costs of obtaining or fulfilling a contract that meet the criteria in ASC 340, Other Assets and 
Deferred Costs, are capitalized and amortized on a systematic basis that is consistent with the transfer of goods or services to the 
customer.  Deferred contracts costs are reported on our consolidated balance sheet within current or non-current other assets based 
on the expected life of the related contract.  At December 31, 2018, we had $7.8 million of deferred contract costs related to the 
fulfillment of future contract obligations.  For the year ended December 31, 2018 we recorded amortization expense of $0.5 million. 

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 include stock-based compensation, as well as 
depreciation  and  amortization  expenses  related  to  the  general  and  administrative  function.    We  recognize  interest  related  to 
unrecognized tax benefits within interest expense and penalties related to unrecognized tax benefits in general and administrative 
expenses.   

We classify indirect costs incurred as cost of services and general and administrative expenses in the same manner as such 

costs are defined in our disclosure statements under U.S. Government Cost Accounting Standards.

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. 

Property and Equipment - Property and equipment are recorded at original cost to us.  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 shorter of the asset's useful life or the term of the lease. 

Goodwill - 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.  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.

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

Intangibles - Goodwill and Other - 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, Software - 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-

43

lived assets may not be fully recoverable, we evaluate the probability that future undiscounted net cash flows 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. 

Employee Supplemental Savings Plan (ESSP) 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, Compensation - General - 
Deferred Compensation - Rabbi Trust, 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 us.  The assets held by the rabbi 
trusts  are  recorded  at  cash  surrender  value  in  our  consolidated  financial  statements  as  ESSP  assets  with  a  related  liability  to 
employees recorded as a deferred compensation liability in accrued retirement. 

Stock-based Compensation - We account for stock-based compensation in accordance with ASC 718, Compensation - Stock 
Compensation, which 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 of stock options on the dates of grant for our stock options.  
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.  The grant date fair value of the restricted stock is equal to the closing market price of our 
common stock on the date of grant.  The compensation expense for restricted stock is recognized over the service period and is 
based on the grant date fair value of the shares.  The grant date fair value of the restricted stock unit (RSU) is equal to the closing 
market price of our common stock on the grant date less the present value of dividends expected to be awarded during the service 
period.  We recognize the grant date fair value of RSUs of shares we expect to issue as compensation expense ratably over the 
requisite service period.  We account for forfeitures as they occur.   

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 
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) consists of net income; 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 (VIEs) - We determine whether we have a controlling financial interest in a 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.  These contracts ended in 2018.  The maximum amount of loss we were exposed to 
as of December 31, 2018 was not material to our consolidated financial statements.

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 earnings or losses of unconsolidated subsidiaries on our consolidated 
statement of income.

44

Investments where we have less than 20% ownership interest in the investee and lack the ability to exercise significant influence 
are accounted for under the cost method.  Under the cost method, we recognize our investment in the stock of an investee as an 
asset.  The investment is measured initially at cost.  We recognize as income dividends received that are distributed from net 
accumulated earnings.  Dividends received in excess of earnings are considered a return of investment and are recorded as reductions 
of costs of the investment.  Impairment is assessed at the individual investment level.  An investment is impaired if the fair value 
of the investment is less than its costs.  If it is determined that the impairment is other than temporary, then an impairment loss is 
recognized in earnings.  The fair value of the investment would become the new cost basis of the investment and will not be 
adjusted for subsequent recoveries in fair value.

Business Combinations - The accounting for our business combinations consists of allocating the purchase price to tangible 
and intangible assets acquired and liabilities assumed based on their estimated fair values, with the excess recorded as goodwill. 
We have up to one year from the acquisition date to use information as of each acquisition date to adjust the fair value of the 
acquired assets and liabilities, which may result in material changes to their recorded values with an offsetting adjustment to 
goodwill. 

Recently Adopted ASUs

ASU  2014-09,  Revenue  from  Contracts  with  Customers  (ASC  606),  supersedes  existing  revenue  recognition  guidance, 
including ASC 605-35, Revenue Recognition - Construction-Type and Production-Type Contracts. ASU 2014-09 outlines a single 
set of comprehensive principles for recognizing revenue under GAAP. Among other things, it requires companies to identify 
contractual performance obligations and determine whether revenue should be recognized at a point in time or over time. It also 
requires new, expanded disclosures regarding revenue recognition.  We elected to adopt using the modified retrospective method 
that applied to those contracts that were not substantially completed as of January 1, 2018.  Additional details are included in the 
revenue recognition policy above and Note 3 below.

ASU  2017-09,  Compensation—Stock  Compensation  (ASC  718):  Scope  of  Modification  Accounting,  provides  guidance 
concerning which changes to the terms or conditions of a share-based payment award require an entity to apply modification 
accounting in ASC 718.  Specifically, an entity is to account for the effects of a modification, unless all of the following are 
satisfied: (1) the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the modified 
award is the same as the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of 
the original award immediately before the original award is modified; (2) the vesting conditions of the modified award are the 
same as the vesting conditions of the original award immediately before the original award is modified; and (3) the classification 
of the modified award as an equity instrument or as a liability instrument is the same as the classification of the original award 
immediately before the original award is modified.  The current disclosure requirements in ASC 718 apply regardless of whether 
an entity is required to apply modification accounting under the amendments in ASU 2017-09.  The adoption of this ASU on 
January 1, 2018 did not have an effect on our consolidated financial statements.

ASU 2017-01, Business Combinations (ASC 805)—Clarifying the Definition of a Business, clarifies the definition of a business 
with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions 
(or disposals) of assets or businesses.  Under the guidance in Topic 805, there are three elements of a business: inputs, processes 
and outputs.  While an integrated set of assets and activities (collectively, a “set”) that is a business usually has outputs, outputs 
are not required to be present. Additionally, all of the inputs and processes that a seller uses in operating a set are not required if 
market participants can acquire the set and continue to produce outputs.  The amendments in ASU 2017-01 provide a screen to 
determine when a set is not a business.  The screen requires that when substantially all of the fair value of the gross assets acquired 
(or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business.  This 
screen reduces the number of transactions that need to be further evaluated.  If, however, the screen is not met, then the amendments 
in this ASU (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that 
together significantly contribute to the ability to create outputs and (2) remove the evaluation of whether a market participant 
could replace missing elements.  Finally, the amendments in this ASU narrow the definition of the term “output” so that the term 
is consistent with the manner in which outputs are described in ASC 606.  The adoption of this ASU on January 1, 2018 did not 
have an effect on our consolidated financial statements.

ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU 
addresses the following eight specific cash flow issues: Debt prepayment or debt extinguishment costs; settlement of zero coupon 
debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate 
of the borrowing; contingent consideration payments made after a business combination; proceeds from the settlement of insurance 
claims; proceeds from the settlement of corporate-owned life insurance policies (including bank-owned life insurance policies); 
distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable 
cash flows and application of the predominance principle.  We applied the equity method of accounting for applicable investments.  
45

 
We made an accounting policy election to classify distributions received from equity method investees using the cumulative 
earnings approach.  Distributions received are considered returns on investment and classified as cash inflows from operating 
activities, unless the investor’s cumulative distributions received less distributions received in prior periods that were determined 
to be returns of investment exceed cumulative equity in earnings recognized by the investor (as adjusted for amortization of basis 
differences).  When such an excess occurs, the current-period distribution up to this excess is considered a return of investment 
and should be classified as cash inflows from investing. Due to the adoption of ASU 2016-15 on January 1, 2018, we classified 
proceeds from settlements of corporate-owned life insurance policies as investing activities on our consolidated statement of cash 
flows for the year ended December 31, 2018.

Recently Issued But Not Yet Adopted ASUs 

The FASB has issued ASU 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 
and Topic 606, which resolves the diversity in practice concerning the manner in which entities account for transactions on the 
basis of their view of the economics of the collaborative arrangement.  A collaborative arrangement, as defined by the guidance 
in Topic 808, is a contractual arrangement under which two or more parties actively participate in a joint operating activity and 
are exposed to significant risks and rewards that depend on the activity’s commercial success.  In particular, the amendments in 
ASU 2018-18 (1) clarify that certain transactions between collaborative participants should be accounted for as revenue under 
Topic 606 when the collaborative participant is a customer in the context of the unit of account, and that, in those situations, all 
the guidance in Topic 606 should be applied, including recognition, measurement, presentation, and disclosure requirements; (2) 
add unit-of-account guidance in Topic 808 to align with the guidance in Topic 606 (i.e., a distinct good or service), limited to when 
an entity is assessing whether the collaborative arrangement or a part of the arrangement is within the scope of Topic 606; and (3) 
clarify that in a transaction that is not directly related to sales to third parties, presenting the transaction as revenue would be 
precluded if the collaborative participant counterparty was not a customer.  The amendments are effective for fiscal years beginning 
after December 15, 2019, and for interim periods within those fiscal years.  Note that early adoption is permitted, including adoption 
in any interim period for public business entities for periods for which financial statements have not yet been issued.  We are 
currently evaluating the effect on our consolidated financial statements.

The FASB issued ASU 2016-02, Leases (Topic 842).  The amendments in this ASU create Topic 842, Leases, and supersede 
the leases requirements in Topic 840, Leases.  The objective of Topic 842 is to establish the principles that lessees and lessors 
should apply to report useful information to users of financial statements about the amount, timing and uncertainty of cash flows 
arising from a lease.  This ASU is effective for public entities for annual periods after December 15, 2018, and interim periods 
therein.  Early adoption is permitted for all entities.  We developed and substantially completed a detailed implementation plan 
which  includes;  implementing  a  software  platform  for  lease  accounting;  updating  our  policies  and  controls;  and  developing 
disclosures.  We will adopt ASU 2016-02 retrospectively at the beginning of the period of adoption, January 1, 2019, through a 
cumulative adjustment to retained earnings and the recognition of a lease liability and corresponding right of use asset.  We will 
elect the following transition related practical expedients; not to reassess whether any expired or existing contracts are or contain 
leases, not to reassess lease classification as determined under ASC 840 and, not to reassess initial direct costs for any existing 
lease.  We have also elected not to apply the recognition and measurement requirements to short-term leases (less than 1 year).  
We expect the adoption of ASU 2016-02 to have a material effect on our consolidated financial statements resulting from the 
recognition of a lease liability of approximately $125 million and right of use asset of approximately $115 million as well as 
significant additional disclosures required under the ASU.  The adoption will not impact financial covenant calculations required 
under our existing credit agreement.

The FASB has issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure
Requirements for Fair Value Measurement, which focuses on improving the effectiveness of disclosures in the notes to financial 
statements by facilitating clear communication of the information required by GAAP that is most important to users of each entity’s 
financial statements.  The amendments in ASU 2018-13 modify the disclosure requirements on fair value measurements in Topic 
820, Fair Value Measurement.  Specifically, the amendments in this ASU remove disclosure requirements in Topic 820 related to 
(1) the amount of, and reasons for, transfers between Level 1 and Level 2 of the fair value hierarchy; (2) the policy for timing of 
transfers between levels; (3) the valuation processes for Level 3 fair value measurements.  Additionally, the ASU adds disclosure 
requirements for public entities about (1) the changes in unrealized gains and losses for the period included in other comprehensive 
income for recurring Level 3 fair value measurements held at the end of the reporting period, and (2) the range and weighted 
average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments are effective for 
fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2019.  The amendments regarding 
changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 
3 fair value measurements and the narrative description of measurement uncertainty should be applied prospectively for only the 
most recent interim or annual period presented in the initial fiscal year of adoption.  All other amendments should be applied 
retrospectively to all periods presented upon their effective date.  Note that early application is permitted for all entities; moreover, 
an entity is allowed to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the 
46

additional  disclosures  until  their  effective  date. We  do  not  expect  the  adoption  of  this ASU  to  have  a  material  effect  on  our 
consolidated financial statements.

The  FASB  has  issued ASU  2018-17,  Consolidation  (Topic  810):  Targeted  Improvements  to  Related  Party  Guidance  for 
Variable Interest Entities, which reduces the cost and complexity of financial reporting associated with consolidation of variable 
interest entities (VIEs).  Specially, the indirect interests held through related parties in common control arrangements should be 
considered on a proportional basis (as opposed to a direct interest in its entirety) for determining whether fees paid to decision 
makers and service providers are variable interests.  This is consistent with how indirect interests held through related parties 
under common control are considered for determining whether a reporting entity must consolidate a VIE.  The amendments are 
effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years.  We do not expect 
the adoption of this ASU to have a material effect on our consolidated financial statements.

The FASB has issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s
Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of 
the FASB Emerging Issues Task Force), which aims to reduce complexity in the accounting for costs of implementing a cloud 
computing service arrangement.  In fact, ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in 
a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop 
or  obtain  internal-use  software  (and  hosting  arrangements  that  include  an  internal-use  software  license).   Accordingly,  the 
amendments in this ASU require an entity (customer) in a hosting arrangement that is a service contract to follow the guidance in 
Subtopic 350-40, Intangibles—Goodwill and Other—Internal-Use Software, in order to determine which implementation costs 
to capitalize as an asset related to the service contract and which costs to expense.  Costs to develop or obtain internal-use software 
that cannot be capitalized under Subtopic 350-40 (e.g., training costs and certain data conversion costs) also cannot be capitalized 
for a hosting arrangement that is a service contract.  Additionally, the amendments in this ASU require the entity (customer) to 
expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting 
arrangement (i.e., the noncancellable period of the arrangement plus periods covered by (1) an option to extend the arrangement 
if the customer is reasonably certain to exercise that option, (2) an option to terminate the arrangement if the customer is reasonably 
certain not to exercise the termination option, and (3) an option to extend (or not to terminate) the arrangement in which exercise 
of the option is in the control of the vendor.  The amendments in this ASU also require the entity to present the expense related to 
the capitalized implementation costs in the same line item in the statement of income as the fees associated with the hosting element 
(service) of the arrangement, and to classify payments for capitalized implementation costs in the statement of cash flows in the 
same manner as payments made for fees associated with the hosting element.  Note that the accounting for the service element of 
a hosting arrangement that is a service contract is not affected by the amendments in this ASU.  The amendments are effective for 
fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years. We are currently evaluating 
methods of adoption as well as the effect on our consolidated financial statements.

The FASB has issued ASU 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-
Based  Payment  Accounting  which  supersedes  the  guidance  in  Subtopic  505-50,  Equity—Equity-Based  Payments  to  Non-
Employees. In particular, ASU 2018-07 expands the scope of topic 718, Compensation—Stock Compensation (which previously 
only included payments to employees), to include share-based payment transactions for acquiring goods and services from non-
employees.  In fact, an entity should now apply the requirements of Topic 718 to non-employee awards, except for specific guidance 
on inputs to an option pricing model and the attribution of cost (i.e., the period of time over which share-based payment awards 
vest and the pattern of cost recognition over that period).  Additionally, the amendments specify that Topic 718  applies to all 
share-based payment transactions in which a grantor acquires goods or services to be used or consumed in the grantor’s own 
operations by issuing share-based payment awards, and clarify that Topic 718 does not apply to share-based payments used to 
effectively provide (1) financing to the issuer, or (2) awards granted in conjunction with selling goods or services to customers as 
part of a contract accounted for under Topic 606, Revenue from Contracts with Customers.  The amendments are effective for 
fiscal years beginning after December 15, 2019, and for interim periods with fiscal years beginning after December 15, 2020. 
Early adoption is permitted, including adoption in any interim period, for reporting periods for which financial statements have 
not yet been issued.  We do not expect the adoption of this ASU to have a material effect on our  consolidated financial statements.

The FASB has issued ASU 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of
Certain Tax Effects from Accumulated Other Comprehensive Income, which helps organizations reclassify certain stranded income 
tax effects in accumulated other comprehensive income resulting from the Tax Cuts and Jobs Act of 2017 (TCJA), enacted on 
December 22, 2017.  Specifically, this ASU allows a reclassification from accumulated other comprehensive income to retained 
earnings  for  stranded  tax  effects  resulting  from  the TCJA,  eliminating  the  stranded  tax  effects  resulting  from  the TCJA  and 
improving  the  usefulness  of  information  reported  to  financial  statement  users.    Because  the  amendments  only  relate  to  the 
reclassification of the income tax effects of the TCJA, the underlying guidance that requires that the effect of a change in tax laws 
or rates be included in income from continuing operations is not affected.  Additionally it requires financial statement preparers 
to disclose (1) a description of their accounting policy for releasing income tax effects from accumulated other comprehensive 
47

income, (2) whether they elect to reclassify the stranded income tax effects from the TCJA and (3) information about other income 
tax effects related to the application of the TCJA that are reclassified from accumulated other comprehensive income to retained 
earnings, if any.  The amendments are effective for annual periods, and for interim periods within those annual periods, beginning 
after December 15, 2018.  Early adoption is permitted, including adoption in any interim period, for reporting periods for which 
financial statements have not yet been issued.  We do not expect the adoption of this ASU to have a material effect on our consolidated 
financial statements.

The  FASB  has  issued ASU  2017-04,  Intangibles—Goodwill  and  Other  (Topic  350):  Simplifying  the  Test  for  Goodwill 
Impairment, which simplifies the manner in which an entity determines the amount of a goodwill impairment by eliminating Step 
2 from the goodwill impairment test.  Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting 
unit’s goodwill with the carrying amount of that goodwill.  In computing the implied fair value of goodwill under Step 2, an entity, 
prior to the amendments in ASU 2017-04, had to perform procedures to determine the fair value at the impairment testing date of 
its assets and liabilities, including unrecognized assets and liabilities, in accordance with the procedure that would be required in 
determining the fair value of assets acquired and liabilities assumed in a business combination.  Under the amendments in this 
ASU, an entity should (1) perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit 
with its carrying amount and (2) recognize an impairment charge for the amount by which the carrying amount exceeds the reporting 
unit’s fair value, with the understanding that the loss recognized should not exceed the total amount of goodwill allocated to that 
reporting unit.  Public entities should adopt the amendments in this ASU prospectively for their annual, or any interim periods, in 
fiscal years beginning after December 15, 2019.  Early adoption is permitted for all entities for interim or annual goodwill impairment 
tests performed on testing dates after January 1, 2017.  We do not expect the adoption of this ASU to have a material effect on our 
consolidated financial statements.

Other ASUs  effective  after  December 31,  2018  are  not  expected  to  have  a  material  effect  on  our  consolidated  financial 

statements.

3.  Revenue from Contracts with Customers

We derive revenue from contracts with customers primarily from contracts with the U.S. government in the areas of defense, 
intelligence, homeland security and other federal civilian agencies.  Substantially all of our revenue is derived from services and 
solutions provided to the U.S. government or to prime contractors supporting the U.S. government, including services by our 
employees and our subcontractors, and solutions that include third-party hardware and software that we purchase and integrate 
as a part of our overall solutions.  Customer requirements may vary from period-to-period depending on specific contract and 
customer requirements.  We provide our services and solutions under three types of contracts: cost-reimbursable, fixed-price and 
time-and-materials.  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 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.  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  have  one  reportable  segment.    Our  U.S.  government  customers  typically  exercise  independent  decision-making  and 
contracting authority.  Offices or divisions within an agency or department of the U.S. government may directly, or through a 
prime contractor, use our services as a separate customer as long as the customer has independent decision-making and contracting 
authority within its organization.  We treat sales to U.S. government customers as sales within the U.S. regardless of where the 
services are performed.  

The following tables disclose revenue (in thousands) by contract type, customer, prime or subcontractor and geography for 

the periods presented.  Prior period amounts have not been adjusted under the modified retrospective method.

Receivables at December 31, 2018 are expected to be substantially collected within one year except for approximately $0.8 
million, of which 94% is related to receivables from sales to the U.S. government or from contracts in which we acted as a 
subcontractor to other contractors selling to the U.S. government.  We have one contract which accounts for 12% of our accounts 
receivable balance.  We do not believe that we have significant exposure to credit risk as billed receivable and unbilled receivables 
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.

Changes in the balance of contract liabilities are primarily due to the timing difference between our performance and our 
customers' payments.  For the year ended December 31, 2018, the amount of revenue that was included in the opening contract 
liabilities balance was $18.2 million. 

The remaining performance obligation at December 31, 2018 was $2.8 billion. The following table discloses when we expect

4.  Acquisitions

InfoZen LLC (InfoZen)—On October 2, 2017, we completed the acquisition of InfoZen.  The results of InfoZen's operations 
have been included in our consolidated financial statements since that date.  The acquisition was completed through an equity 
purchase  agreement  dated  September 15,  2017,  by  and  among  InfoZen  LLC.,  IZ  Holdings,  LLC  and  other  beneficiaries  and 
ManTech Advanced Systems International, Inc.  We funded the acquisition with cash on hand and borrowings on our revolving 
credit  facility.    InfoZen  is  a  leading  IT  solution  provider,  with  domain  expertise  in  modernization,  agile/DevOps  software 
development, cloud migration and threat monitoring and assessment capabilities in support of critical national and homeland 
security missions.  The purchase agreement did not contain provisions for contingent consideration. 

For the year ended December 31, 2017, we incurred approximately $0.8 million of acquisition costs related to the InfoZen 

transaction, which are included in general and administrative expenses in our consolidated statement of income. 

The purchase price of $184.0 million was allocated to the underlying assets and liabilities based on their estimated fair value 
at the date of acquisition.  The goodwill recorded related to this transaction will be deductible for tax purposes over 15 years.  
Recognition of goodwill is largely attributed to the value paid for InfoZen's capabilities to support customers in modernization, 
agile software development, cloud migration and threat monitoring assessment capabilities.  

In allocating the purchase price, we considered, among other factors, analysis of historical financial performance and estimates 
of future performance of InfoZen's contracts.  The components of other intangible assets associated with the acquisition were 
customer  relationships  and  backlog  valued  at  $49.2  million  and  $5.7  million,  respectively.    Customer  contracts  and  related 
relationships represent the underlying relationships and agreements with InfoZen's existing customers.  Customer relationships 
are amortized using the pattern of benefits method over their estimated useful lives of approximately 20 years.  Backlog is amortized 
straight-line over its estimated useful life of 1 year.  The weighted-average amortization period for the intangible assets is 18 years.

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

In applying the two-class method, we determined that undistributed earnings 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, 2018, 2017 and 2016, we declared and paid quarterly 
dividends, in the amount of $0.25, $0.21 and $0.21 per share on both classes of common stock. 

Basic earnings per share has been computed by dividing net income 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 per share have been 
computed in a manner consistent with that of basic earnings per share while giving effect to all potentially dilutive common shares 

50

that were outstanding during each period. 

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

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 annual review as of October 31st of each calendar year.

In reviewing goodwill for impairment, we have the option to first assess qualitative factors to determine whether the existence 
of events or circumstances leads to a determination that it is more likely than not that the estimated fair value of a reporting unit 
is less than its carrying amount.  If we elect to perform a qualitative assessment and determine that an impairment is more likely 
than not, the entity is then required to perform the existing two-step quantitative impairment test (described below), otherwise no 
further analysis is required.  We also may elect not to perform the qualitative assessment and, instead, proceed directly to the two-
step quantitative impairment test. 

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 us.  Valuation ratios, which relate market prices to selected financial statistics 
derived from comparable companies, are selected and  applied to us 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 provides a reasonable basis for comparison to us.  Valuation ratios, which 
relate  market  prices  to  selected  financial  statistics  derived  from  comparable  companies,  are  selected  and  applied  to  us  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 our 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.

Revolving Credit Facility - We maintain a credit agreement with a syndicate of lenders led by Bank of America, N.A., as sole 
administrative agent.  The credit agreement provides for a $500 million revolving credit facility, with a $75 million letter of credit 
sublimit and a $30 million swing line loan sublimit.  The credit agreement also includes an accordion feature that permits us to 
arrange with the lenders for the provision of additional commitments.  The maturity date is August 17, 2022. 

Borrowings under our credit agreement are collateralized by substantially all of our assets and our Material Subsidiaries (as 
defined in the credit agreement) and bear interest at one of the following variable rates as selected by us at the time of borrowing: 
a 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 3.91% and 2.99% for the years ended December 31, 2018 and 2017, 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 us to comply with specified financial covenants, including the maintenance of certain 
leverage  ratios  and  a  certain  consolidated  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 other actions.  As of, and during the fiscal years ending, December 31, 
2018 and 2017, we were in compliance with our financial covenants under the credit agreement.  

There  was  $7.5  million  and  $31.0  million  outstanding  on  our  revolving  credit  facility  at  December 31,  2018  and  2017, 
respectively.  The weighted average borrowings under the revolving portion of the facility during the years ended December 31, 
2018 and 2017 were $34.2 million and $2.7 million, respectively.  The maximum available borrowing under the revolving credit 
facility at December 31, 2018 was $482.9 million.  At December 31, 2018 and 2017, we have $9.6 million and $15.3 million, 
respectively, outstanding on our letter of credit that reduces our availability to borrow under our revolving credit facility.

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 us, 
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 us, or could lead to suspension or debarment from future 
U.S. government contracting activities.  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 has completed our incurred cost audits through 
2015 with adjustments expected to be settled within established reserves.  The remaining audits for 2016 through 2018 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, except for the matter noted below.

An officer of our Company is a party to a pending arbitration proceeding with a former employer that relates to certain breach 
of contract claims.  Pursuant to indemnification arrangements we have with this officer, we may be exposed to a potential loss 
related to this claim.  Pursuant to applicable accounting standards, we have determined that it is not probable that an unfavorable 
outcome could cause us to incur a liability/loss under these indemnification arrangements.  However, given the nature of the claim, 
the early stage of the process, the limitations on information and other factual details relating to the claims that are available to 
us at this time and management’s intent to contest the matter vigorously, we are unable to make a reasonable estimate of loss at 
this time.  As such, we have not accrued, nor disclosed an amount of potential loss as of December 31, 2018.

We were a defendant in a lawsuit filed by two former employees with allegations of retaliation under both the False Claims 
Act and the Defense Contractor Whistleblower Protection Act.  A jury found ManTech liable for discharging the two former 
employees.  Both parties filed appeals to the Fourth Circuit Court of Appeals.  In August 2018, the Fourth Circuit Court of Appeals 
reversed the finding of liability as to one of the former employees and affirmed the finding of liability as to the other former 
employee in the amount of $1.4 million.  Our insurance policy covers the amount of the liability, therefore, no loss was recognized 
for the year ended December 31, 2018.  The impact of future events in connection with this matter is not expected to have a material 
effect on our financial position, results of operations or cash flow.

We have $9.6 million outstanding on our letter of credit, of which $9.5 million is related to an outstanding performance bond 
in connection with a contract between ManTech MENA, LLC and Jadwalean International Operations and Management Company 
to fulfill technical support requirements for the Royal Saudi Air Force.

We lease office space and equipment under long-term operating leases.  A number of the leases contain renewal options and

for the years ended December 31, 2018, 2017 and 2016, respectively.  We had $13.2 million and $10.6 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

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, 2018, there were 26,573,400
shares of Class A common stock outstanding, 244,113 shares of Class A common stock recorded as treasury stock and 13,188,045
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 Executive Chairman and Chairman of the Board), his affiliates, his direct and indirect permitted 
transferees or a group, generally including Mr. Pedersen, such affiliates and permitted transferees, seek to buy all outstanding 
shares), as to which each share of Class A common stock and Class B common stock are entitled to one vote per share.  The Class A 
common stock and the Class B common stock vote together as a single class on all matters submitted to a vote of stockholders, 
including the election of directors, except as required by law.  Holders of common stock do not have cumulative voting rights in 
the election of directors. 

Stockholders are entitled to receive, when and if declared by the Board of Directors from time-to-time, such dividends and 
other distributions in cash, stock or property from 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 to 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 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, 2018 and 2017, 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 2016 Management Incentive Plan (the Plan) was designed to attract, retain and motivate key employees.  The types of 
awards available under the Plan include stock options, restricted stock and RSUs.  Equity 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, 2019, there were 596,422 additional shares made available for 
issuance under the Plan.  Through December 31, 2018, the Board of Directors has authorized the issuance of up to 14,551,899
shares under this Plan.  Through December 31, 2018, the remaining aggregate number of shares of our common stock available 
for future grants under the Plan was 6,113,209.  The Plan expires in March 2026.

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, 2018, 2017 and 2016, we recorded $5.1 million, $6.3 
million and $3.3 million of stock-based compensation expense, respectively.  No compensation expense of employees with stock 
awards was capitalized during the years ended December 31, 2018, 2017 and 2016.  For the year ended December 31, 2018 and 
2017, we recorded $3.1 million and $2.7 million to income tax expense for tax benefits related to the exercise of stock options, 
vested cancellations and the vesting of restricted stock.  For the year ended December 31, 2016, we recorded $0.1 million to paid 
in capital related to tax deficiencies from the exercise of stock options, vested cancellations and the vesting of restricted stock.

Stock Options - Under the Plan, we have issued stock options.  A stock option granted gives the holder the right, but not the 
obligation to purchase a certain number of shares at a predetermined price for a specific period of time.  We typically issue options 
55

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, 2018, 2017 and 2016, 
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 
stock option awards on the 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, 2018, 2017

and 2016:

•  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 life of options - The expected life of options granted to employees was determined from historical exercises of 
the grantee population.  The options had 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 the expected term of the underlying grants.  

•  Dividend yield - The Black-Scholes-Merton valuation model requires an expected dividend yield as an input.  For the 
years ended December 31, 2018, 2017 and 2016, we have calculated our expected dividend yield based on an expected 
annual cash dividend of $1.00 per share, $0.84 per share and $0.84 per share, respectively.

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

December 31, 2018, 2017 and 2016:

Stock Option Activity - The weighted-average fair value of options granted during the years ended December 31, 2018, 2017
and 2016, as determined under the Black-Scholes-Merton valuation model, was $10.42, $6.75 and $4.60, respectively.  Option 
grants that vested during the years ended December 31, 2018, 2017 and 2016 had a combined fair value of $1.5 million, $1.7 
million and $2.6 million, respectively.

Unrecognized compensation expense related to outstanding stock options was $5.6 million as of December 31, 2018, which 

is expected to be recognized over a weighted-average period of 2 years and will be adjusted for forfeitures as they occur.

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 stock issued to members of 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.  The grant date fair value of the restricted stock is equal to the 
closing market price of our common stock on the date of grant.

RSUs - Under the Plan, we issued performance-based and time-based RSUs.  RSUs are not actual shares, but rather a right 
to receive shares in the future.  The shares are not issued and the employee cannot sell or transfer shares prior to vesting and has 
no voting rights until the RSUs vest.  Employees who are granted RSUs do not receive dividend payments during the vesting 
period.  The employees' performance-based RSUs will result in the delivery of shares if (a) performance criteria is met and (b) 
the employee remains employed, in good standing, through the date of the performance period of 2 years.  The employees' time-
based RSUs will result in the delivery of shares in one-third increments on the first, second and third anniversaries of the date of 
grant. The grant date fair value of the RSUs is equal to the closing market price of our common stock on the grant date less the 
present value of dividends expected to be awarded during the service period. We recognize the grant date fair value of RSUs of 
shares we expect to issue as compensation expense ratably over the requisite service period.

RSU Activity - For performance-based RSUs that vested in 2018, each RSU awarded resulted in the issuance of 1.5 shares, 
which were issued net of applicable payroll tax withholdings. The following table summarizes the RSU activity during the years 
ended December 31, 2018 and 2017:

As of December 31, 2018, 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 we 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 $23.5 million, 
$20.6 million and $19.8 million for the years ended December 31, 2018, 2017 and 2016, respectively. 

As of December 31, 2018, we also maintained an Employee Supplemental Savings Plan (ESSP), which is a nonqualified 
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 us for 
benefit of the participating employees.  The trust investments are in the form of variable universal life insurance products, which 

58

are owned by us.  These investments seek to replicate the return of the participant investment elections.  Employee contributions 
to this plan were approximately $3.4 million, $3.0 million and $2.6 million for the years ended December 31, 2018, 2017 and 
2016, respectively.

We maintained a nonqualified supplemental defined benefit pension plan for certain retired employees of an acquired company 
as of December 31, 2018.  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, 2018 and 2017, 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 was $0.8 million and $1.2 million at December 31, 2018 and 2017, respectively.

The Tax Cuts and Jobs Act of 2017 (TCJA) was enacted on December 22, 2017, TCJA reduced the U.S. federal corporate tax 
rate from 35% to 21% effective January 1, 2018.  At December 31, 2017, we made a reasonable estimate of the effects on our 
existing deferred tax balances and effective tax rate for the deductibility of officer's compensation, the acquisition of InfoZen and 
assets that qualify for an immediate deduction.  Our accounting for those items, as impacted by the TCJA, is now complete and 
no material adjustments were required.  The re-measurement of the deferred taxes at December 31, 2017 due to the decrease in 
the federal corporate tax rate resulted in a decrease to income tax expense of $50.6 million and reduced the 2017 effective tax rate 
by 52.0%.  After the 2017 corporate tax return was filed the adjustment related to the re-measurement of the deferred taxes changed 
by an immaterial amount.  

At  December 31,  2018,  we  had  state  and  foreign  net  operating  losses  of  approximately  $10.3  million  and  $5.7  million, 
respectively.  The state net operating losses expire beginning 2020 through 2036.  We recorded a full valuation allowance against 
the foreign net operating losses and a partial valuation allowance against the state net operating losses, as we do not believe those 
losses will be fully utilized in the future.

The total liability for gross unrecognized tax benefits as of December 31, 2018, 2017 and 2016 includes $0.4 million, $0.2 
million and $0.2 million, respectively, of unrecognized net tax benefits which, if ultimately recognized, would reduce our annual 
effective tax rate in a future period.

We are 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.  We are no longer subject to U.S. federal or 
non-U.S.  income  tax  examinations  by  tax  authorities  for  the  years  before  2014.   We  are  no  longer  subject  to  U.S.  state  tax 
examinations by tax authorities for the years before 2013.  We believe it is reasonably possible that no gross unrecognized tax 
benefits will be settled within the next year due to expirations of statute of limitations.

Changes in and Disagreements with Accountants on Accounting and Financial Disclosure 

We have had no disagreements with our 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 

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, does 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 us have been detected.  These inherent limitations include the realities that judgments in decision-making can be faulty 
and that breakdowns can occur because of a 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 
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 Internal 
Control-Integrated Framework (2013) 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 
63

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, 2018, 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 Internal Control-Integrated Framework (2013) to assess the effectiveness of 
our internal control over financial reporting.  Based upon the assessments, our management has concluded that, as of December 31, 
2018, 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, 2018, 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 shareholders and the Board of Directors of ManTech International Corporation

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of ManTech International Corporation and subsidiaries (the 
“Company”) as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued 
by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (COSO).  In  our  opinion,  the  Company 
maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on 
criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the consolidated financial statements as of and for the year ended December 31, 2018, of the Company and our 
report dated February 22, 2019 expressed an unqualified opinion on those financial statements.

Basis for Opinion 

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 are a public accounting firm registered with the PCAOB and are 
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable 
rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. 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.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed 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 its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

All statements and assumptions contained in this Annual Report
that do not relate to historical facts constitute “forward-looking
statements.” These statements can be identified by the fact that
they do not relate strictly to historical or current facts. Forward-
looking statements often include the use of words such as
“may,” “will,” “expect,” “intend,” “anticipate,” “believe,” “estimate,” “plan,” 
and words and terms of similar substance in connection with 
discussions of future events, situations or financial performance. 
While these statements represent our current expectations, no
assurance can be given that the results or events described in such 
statements will be achieved.

These forward-looking statements are inherently subject to risks
and uncertainties, and 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. Factors include, but are not limited to, the following: 
failure to maintain our relationship with the U.S. government, or
compete effectively for contract awards; inability to recruit and
retain sufficient number of employees with specialized skill sets 
or necessary security clearances who are in great demand and
limited supply; adverse changes in U.S. government spending
for programs we support, whether due to changing mission 
priorities, socio-economic policies, cost reduction initiatives by 
our customers, or other federal budget constraints generally; 
disruption of our business or damage to our reputation resulting
from security breaches in customer systems, internal systems 
(including as a result of cyber or other security threats), or 
employee misconduct; failure to realize the full amount of our
backlog or adverse changes in the timing of receipt of revenues 
under contracts included in backlog; issues relating to competing
effectively for awards procured through the competitive bidding 
process; failure to obtain option awards, task orders or funding 
under contracts; renegotiation, modification or termination of 
our contracts, or failure to perform in conformity with contract 
terms or our expectations; failure to successfully integrate acquired
companies or businesses into our operations or to realize any
accretive or synergistic effects from such acquisitions; non-
compliance with, or adverse changes in, complex U.S. government
laws, procurement regulations or processes; and adverse results of 
U.S. government audits or other investigations of our government
contracts. These and other risk factors are more fully discussed
in the section entitled “Risk Factors” in ManTech’s Annual Report
on Form 10-K previously filed with the Securities and Exchange
Commission on Feb. 22, 2019, 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 Annual Report.
We undertake no obligation to update any forward-looking 
statement made herein following the date of this Annual Report, 
whether as a result of new information, subsequent events or
circumstances, changes in expectations or otherwise.
