2018 ANNUAL REPORT

Message from Chairman and CEO Sudhakar Kesavan

As ICF approaches the 50th anniversary of our founding, I think it is worthwhile to look back with pride on what
we have accomplished since the 2006 Initial Public Offering. In the more than 12 years since that time, the firm
has changed and grown substantially while staying true to our core values and our commitment to sustainability.
Some salient elements of our performance during this time include:



ICF’s cumulative average annual total shareholder return (TSR) from the time we went public through
2018 was 14.3 percent, while the NASDAQ Composite was up 9.2 percent per year over the same
period. Our total shareholder return has exceeded our peers who have been public during this same
period.

 We grew four-fold in revenue, from $331 million in 2006 to $1.338 billion in 2018.
 Our EBITDA has grown from $26.5 million to $119.5 million, a 4.5-fold increase.
 Our backlog, which stood at $972 million in 2006 after winning the iconic Road Home Program, now

stands at $2.4 billion.

 We have stayed true to our commitment to sustainability by being carbon neutral since 2006.

This performance has been the result of hard work by thousands of employees and a thoughtful approach to
expanding ICF’s reach. We have broadened our portfolio to drive growth, increase earnings, and mitigate risk.
We have added implementation services to our original advisory focus. From a primarily federally-focused
business we have expanded to a more balanced mix of revenues that includes material commercial revenue. We
have diversified geographically by expanding into Europe and Asia. We have been focused on establishing a
significant presence in businesses with uncorrelated revenue sources that can nevertheless benefit from our
unique combination of knowledge and capabilities.

2018 Performance

2018 was a year of solid growth for ICF.

 Our revenue increased 8.9 percent to $1.338 billion as we continued to expand our presence in our key

markets.

 We achieved record contract awards of over $1.8 billion.


ICF delivered $3.18 in diluted GAAP earnings per share and $3.73 in Non-GAAP EPS, up 24 percent
from 2017.

We remain focused on delivering value for our clients, opportunities for our people, and returns to our
shareholders in an increasingly volatile world. Our performance in 2018 continued to show the benefit of our
strategy to serve clients in multiple markets.

 Our commercial energy business continued its growth as we assisted utilities to transform their

businesses and deliver Demand Side Management programs to their customers.

 We leveraged our creative and award-winning marketing and communications services to grow our



clients’ revenues and were recognized as a Strong Performer in the first Forrester Midsize Digital
Experience Agency Wave.
In our U.S. federal government businesses, we continued to support many of the nation’s most
essential missions although we were affected by the partial government shutdown at the very end of
2018. ICF helps government leaders across the world deliver value and transform how services are
delivered to citizens.

 Our excellence in helping communities recover from disasters has resulted in ICF earning the

opportunity to work with the Commonwealth of Puerto Rico, Texas, and the US Virgin Islands to
recover from Hurricanes Harvey, Irma, and Maria.

In 2018, ICF added three acquisitions designed to enhance our capabilities. In January, we acquired The Future
Customer Ltd. (TFC), a marketing consultancy based in London. TFC specializes in harnessing customer
insight to grow brand loyalty and advocacy while improving marketing efficiency and profitability. In October,
we added We Are Vista Ltd. (WAV), also based in the UK. WAV brings communications strategy, research,
digital engagement, and content development for commercial and government customers. In August, ICF
acquired David M Shapiro Disaster Planning and Recovery Consultants, Inc. (DMS), a small firm engaged in
helping local and state governments plan for and recover from disasters. DMS was already an ICF teammate in
assisting Puerto Rico in its disaster recovery efforts and enhances our abilities to support other jurisdictions both
before and after disasters strike.

We recently unveiled ICF Next, the convergence of ICF’s award-winning marketing, communications and
associated technology businesses. ICF Next will support a full range of capabilities all grounded in behavioral
insights, creative engagement and technology. The talent that makes up ICF Next will be comprised of teams
that have grown within ICF organically, primarily focused on public sector clients, or through acquisition,
including North America-based Olson Engage, Olson1to1, Olson Digital, and PulsePoint Group, Brussels-based
ICF Mostra, and U.K.-based TFC and WAV.

Increased levels of uncertainty appear to be a permanent feature of the market environment faced by ICF.
Capital markets have become substantially more volatile and corporate tax cuts have not yielded a material
increase in corporate investment. The UK has yet to determine how it will implement the Brexit decision, with
major implications both for it and the EU. The political environment in the US has become more fraught with
the change of control in the House and history’s longest Federal shutdown in early 2019. Nevertheless, ICF’s
mix of businesses, agile workforce, and strong client relationships continue to help us navigate these
challenging conditions, and our complementary capabilities and domain expertise allows us to add increasing
value to our customers throughout the year.

Work That Makes Us Proud

ICF is proud of the work we do. While the breadth of this work prevents me from describing every aspect of it
here, below I illustrate a few of the ways in which we make a difference for our clients and the world:

 We are proud to have been awarded the recompete of the MEASURE Demographic and Health Survey
contract for the 7th time by USAID. Long recognized as a gold standard of survey research, the DHS
Program provides vital information and builds in-country analytical capacity to help advance global
understanding of health and population trends in lower and middle income countries.

 We are supporting Puerto Rico’s recovery from Hurricane Maria through our Project Formulation and
Claims Management contract. Not only are we helping get recovery dollars in the hands of Puerto
Rican residents, we employ more than 200 local residents directly and another 200 indirectly as
subcontractors.
ICF is helping the European Union and China implement China’s Emissions Trading System to reduce
carbon dioxide emissions in the world’s largest carbon emitter.



 We continue to serve Amtrak, America’s passenger rail system, as their Loyalty Agency of Record,

growing long-term relationships with customers and enhancing the performance of a key transportation
provider.

 We are implementing several innovative programs to keep Consolidated Edison at the forefront of

utility grid transformation and Distributed Energy implementation.

Beyond these few examples we continue to provide assistance to our wide range of customers from
governments and private sector companies around the world, and we are increasingly finding additional ways to
support them with our broadening value proposition.

Corporate Citizenship

In 2018 ICF’s commitment to our communities and to the causes important to our employees remained strong.
ICF’s 2018 corporate giving totaled $473,000. Aided by our new giving and matching program, our employees
engaged more than ever with our charity partners. Employees volunteered thousands of hours and donated
$140,000 to a variety of causes and philanthropic initiatives. Our employees’ generosity inspires and sets an
example for us all.

Continuing our commitment to minimize our environmental footprint, we again purchased 100% net renewable
electricity for U.S. operations via renewable energy certificates that are Green-e® certified. We also employed
other sustainability tactics, such as prioritizing leases in green buildings, providing online collaboration tools to
reduce the need for business travel, and promoting the commuter transit benefit. We took inventory of our
carbon emissions, including those from facilities, business travel and employee commuting—the three sources
of greatest impact. ICF is proud to have been awarded a grade of A- by CDP (formerly the Carbon Disclosure
Project). Finally, our employee volunteer Green Team bolstered corporate sustainability efforts by leading a
campaign to reduce the footprint of our meetings through mindful actions: Think green. Meet green.

Our People

I am proud to lead ICF and its more than 6000 employees into our 50th year. Over the last half century we have
grown and deepened our expertise and learned many ways of Making Big Things Possible. I know that our
emerging leaders will find even more ways of growing the firm and making the next 50 years even more
exciting. As we grow and change, we will always be true to our values and the passion and commitment
exemplified by our workforce. We look forward to the future and to contributing even more to a safe,
prosperous, and sustainable future around the world.

On to the next 50 years!

ITEM 1. BUSINESS

COMPANY OVERVIEW

PART I

We provide professional services and technology-based solutions to government and commercial clients, including
management, marketing, technology, and policy consulting and implementation services. We help our clients conceive,
develop, implement, and improve solutions that address complex business, natural resource, social, technological, and public
safety issues. Our services primarily support clients that operate in four key markets:

•

Energy, Environment, and Infrastructure;

Health, Education, and Social Programs;

Safety and Security; and

Consumer and Financial.

We provide services across these four markets that deliver value throughout the entire life cycle of a policy, program,

project, or initiative. Our primary services include:

•

Advisory Services. We research critical policy, industry, and stakeholder issues, trends, and behavior. We
measure and evaluate results and their impact and, based on those assessments, provide strategic planning and
advice to our clients on how to navigate societal, market, business, communication, and technology challenges.

Program Implementation Services. We identify, define, and implement policies, plans, programs, and business
tools that make our clients’ organizations more effective and efficient. Our comprehensive, end-to-end solutions
are implemented through a wide range of standard and customized methodologies designed to match our clients’
business context.

Analytics Services. We conduct survey research and collect and analyze wide varieties and large volumes of
data to understand critical issues and options for our clients and provide actionable business intelligence. We
provide information and data management solutions that allow for integrated, purpose-driven data usage.

Digital Services. We design, develop, and implement cutting-edge technology systems and business tools that
are key to our clients’ mission or business performance, and include solutions to optimize the customer and
citizen experience for our clients. We provide cybersecurity solutions that support the full range of cybersecurity
missions and protect evolving IT infrastructures in the face of relentless threats.

Engagement Services. We inform and engage our clients’ constituents, customers, and employees to drive
behavior and outcomes through public relations, branding and marketing, multichannel and strategic
communications, and reputation issues management. Our engagement services frequently rely on our digital
design and implementation skills, such as web and app development.

We perform work for both government and commercial clients. Our government clients include U.S. federal agencies,
state and local governments, as well as governments outside the U.S. Our commercial clients include both U.S. and
international clients. Our clients utilize our services because we offer a combination of deep subject matter expertise, technical
solutions, and institutional experience which ensures that our solutions are beneficial. We believe that our domain expertise
and the program knowledge developed from our advisory engagements further position us to provide our full suite of services.

We report operating results and financial data in one operating and reportable segment. We generated revenue of
$1,338.0 million, $1,229.2 million, and $1,185.1 million in 2018, 2017, and 2016, respectively. Our total backlog was
approximately $2,377.7 million, $1,950.4 million, and $2,122.7 million as of December 31, 2018, 2017, and 2016,
respectively.

As of December 31, 2018, we had more than 7,000 full and part-time employees around the globe, including many
recognized as thought leaders in their respective fields. We serve clients globally from our headquarters in the Washington,
D.C. metropolitan area, our more than 65 regional offices throughout the U.S., and more than 15 offices outside the U.S.,
including offices in the United Kingdom (“U.K.”), Belgium, China, India and Canada.

OUR COMPANY INFORMATION

ICF International, Inc. began as a Delaware limited liability company formed in 1999 under the name ICF Consulting
Group Holdings, LLC. It was formed to purchase our principal operating subsidiary, which was founded in 1969, from a
larger services organization. A number of our current senior managers participated in this transaction, along with private
equity investors. We converted to a Delaware corporation in 2003 and changed our name to ICF International, Inc. in 2006.
We completed our initial public offering in September 2006.

Our principal executive office is located at 9300 Lee Highway, Fairfax, Virginia 22031, and our telephone number
is (703) 934-3000. We maintain an internet website at www.icf.com. We make available our Annual Reports on Form 10-K,
Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and amendments to such reports filed or furnished pursuant
to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and other information
related to us, free of charge, on this site as soon as reasonably practicable after we electronically file those documents with,
or otherwise furnish them to, the SEC. Our internet website and the information contained therein or connected thereto are
not intended to be incorporated into this Annual Report on Form 10-K. The SEC also maintains an internet website that
contains reports, proxy, and information statements and other information, regarding issuers that file electronically with the
SEC at http://www.sec.gov.

MARKET OPPORTUNITY, SERVICES, AND SOLUTIONS

Complex, long-term market factors, which include geopolitical, environmental and demographic trends, are changing
the way people live and the way government and industry operate and interact. Some of these factors have significant impacts
on the markets in which our clients operate.

In the energy, environment, and infrastructure market, these factors include: the changing mix of sources used to
generate electricity and the related policy and infrastructure issues resulting from those changes; the changing position of the
U.S. in the world’s energy markets overall; an ongoing focus on renewables, energy efficiency, climate change, and resilience;
an aging transportation infrastructure; increasing drought and need to invest in water infrastructure and conservation; and
environmental degradation.

In the health, education, and social programs market, these factors include: the increasing level of healthcare
expenditures and efforts at healthcare reform; global public health and health security issues, including potential global
epidemics; aging populations across the globe; increasing military and veteran health demands; continued focus on disease
prevention; the perceived declining performance of the U.S. educational system compared to other countries; and the desire
to find more efficient means to deliver social and educational programs.

In the safety and security market, these factors include: the continuing spectrum of all-hazard threats, including
cybersecurity threats, terrorism, severe weather and climatological changes, as well as infrastructure protection in both the
physical realm and the cyber realms, and the intersection of those two.

In the consumer and financial market, these factors include increased use of interactive data technologies to link
organizations with consumers and other stakeholders in more varied and personalized ways, and less reliance on traditional
print and television marketing; changing industry structures in marketing and advertising services; the desire for greater return
on marketing investment; and the continued elevation of data analytics as a business management and marketing tool, as well
as the concomitant growth of concerns about, and regulation of, data capture and exploitation for marketing and other private
and public sector purposes.

In addition to these market-based factors, trends across all of our markets are increasing the demand for advisory
services that drive our business. These trends include: increased government focus on efficiency and mission performance
management; generational changes; the emphasis on transparency and accountability; and an increased demand for combining
domain knowledge of client mission and programs with innovative technology-enabled solutions. We see growth
opportunities for technology-based solutions involving digital services and strategic communications across all of our
markets.

We believe that demand for our services will continue as government, industry, and other stakeholders seek to
understand and respond to these and other factors. We expect that our government clients will continue to utilize professional
services firms with relevant domain expertise to assist with designing new programs, enhancing existing ones, offering
transformational solutions, and deploying innovative information and communications technology. In addition, commercial
organizations affected by these programs will need to understand such changes, as well as their implications, in order for
them to plan appropriately. More broadly, we believe our commercial clients will demand innovative services and solutions
that can help them connect with customers and stakeholders in an increasingly connected and crowded marketplace. We also
see opportunity to further leverage our digital and client engagement capabilities across our commercial and government
client base. We believe that our institutional knowledge and subject matter expertise are a distinct competitive advantage in
providing our clients with practical, innovative solutions, which are directly applicable to their mission or business, and

deploying them quickly with the right resources. Moreover, we believe we will be able to leverage the domain expertise and
program knowledge we have developed through advisory assignments and our experience with program management,
technology-based solutions, and engagement projects to win larger engagements, which generally lead to increasing returns
on business development investment and promote higher employee utilization. Rapid changes in technology, including the
omnipresent influence of mobile, social, and cloud technologies, also demand new ways of communicating, evaluating and
implementing programs, and we are focused on leveraging our expertise in technology to capitalize on those changes.

Our future results will depend on the success of our strategy to capitalize on our competitive strengths, including our
success in maintaining our long-standing client relationships, to seek larger engagements across the program life cycle and
to complete and successfully integrate strategic acquisitions. We will continue to focus on building scale in vertical and
horizontal domain expertise; developing business with both our government and commercial clients; and replicating our
business model geographically in selected regions of the world. In doing so, we will continue to evaluate strategic acquisition
opportunities that enhance our subject matter knowledge, broaden our service offerings, and/or provide scale in specific
geographies.

While we continue to see favorable long-term market opportunities, there are certain near-term challenges facing all
government service providers. Administrative and legislative actions by the federal government to address changing priorities
could have a negative impact on our business, which may result in a reduction to our revenue and profit and adversely affect
cash flow. However, we believe we are well positioned to provide a broad range of services in support of initiatives that will
continue to be priorities to the federal government as well as to state and local and international governments and commercial
clients.

Our portfolio includes a sizable amount of federal client work and we take active measures to minimize the impact
of any federal government shutdown on our performance and our people. While a significant portion of our federal business
was not impacted by the recent U.S. government shutdown, we did receive stop-work orders for several of our federal
contracts which were lifted once operations resumed in the affected government organizations. We do not anticipate a material
impact on our operations as a result of the shutdown. However, a federal government shutdown of any length is highly
unpredictable for our impacted employees, for our clients, and for us as a company and, in the event of any future shutdowns,
we cannot predict the impact on us or our operations.

Energy, Environment, and Infrastructure

For decades, we have advised on energy and environmental issues, including the impact of human activity on natural
resources, and have helped develop solutions for infrastructure-related challenges. In addition to addressing government
policy and regulation in these areas, our work focuses on industries that are affected by these policies and regulations,
particularly those industries most heavily involved in the use and delivery of energy. Significant factors affecting suppliers,
users, and regulators of energy are driving private and public sector demand for professional services firms, including:

•

Changing power markets, increasingly diverse sources of supply, and an increased demand for alternative
sources of energy and/or energy storage;

Ongoing efforts to upgrade energy infrastructure to meet new power, transmission, environmental, and
cybersecurity requirements and to enable more distributed forms of generation; and

The need to manage energy demand and increase efficient energy use in an era of environmental concerns,
especially regarding carbon and other emissions.

We assist energy enterprises worldwide in their efforts to analyze, develop, and implement strategies related to their
business operations and the interrelationships of those operations with the environment and applicable government
regulations. We utilize our policy expertise, deep industry knowledge, and proprietary modeling tools to advise government
and commercial clients on key topics related to electric power, traditional fuels, and renewable sources of energy. Our areas
of expertise include power market analysis and modeling, transmissions analysis, electric system reliability standards, energy
asset valuation and due diligence, regulatory and litigation support, fuels market analysis, air regulatory strategy, and
renewable energy and green power.

We also assist commercial and government clients in designing, implementing, and evaluating demand side
management programs both for residential and for commercial and industrial sectors. Utility companies must balance the
changing demand for energy with a price-sensitive, environmentally conscious consumer base. We help utilities meet these
needs, guiding them through the entire life cycle of energy efficiency and related demand side management programs,
including policy and planning, determining technical requirements, and program implementation and improvement.

Carbon emissions have been an important focus of federal government regulation, international governments, many
state and local governments, and multinational corporations around the world. Reducing or offsetting greenhouse gas
(“GHG”) emissions continues to be the subject of both public and private sector interest, and the regulatory landscape in this
area is still evolving. The need to address carbon and other harmful emissions has significantly changed the way the world’s
governments and industries interact and continues to be one of the drivers of interest in energy efficiency. Moreover, how
government and business adapt to the effects of climate change continues to be of global importance. We support governments
at the federal and state and local level, including providing comprehensive support to NASA’s Global Change Research
Program. Additionally, we support ministries and agencies of the government of the U.K. and European Commission, as well
as commercial clients, on these and related issues.

We also have decades of experience in designing, evaluating, and implementing environmental policies and
environmental compliance programs for transportation (including aviation) and other infrastructure projects. A number of
key issues are driving increased demand for the services we provide in these areas, including:

•

Increased focus on the proper stewardship of natural resources;

Aging water, energy, and transportation infrastructure, particularly in the U.S.;

The increasing exposure of infrastructure to damage and interference by severe weather events influenced by a
changing climate;

Under-investment historically in transportation infrastructure; and

Changing patterns of economic development that require transportation systems and energy infrastructure to
adapt to new patterns of demand.

By leveraging our interdisciplinary skills, which range from finance and economics to earth and life sciences,
information technology, and program management, we are able to provide a wide range of services that include complex
environmental impact assessments, environmental management information systems, air quality assessments, program
evaluation, transportation and aviation planning and operational improvement, strategic communications, and regulatory
reinvention. We help clients deal specifically with the interrelated environmental, business, and social implications of issues
surrounding all transportation modes and infrastructure. From the environmental management of complex infrastructure
engagements to strategic and operational concerns of airlines and airports, our solutions draw upon our expertise and
institutional knowledge in transportation, urban and land use planning, industry management practices, financial analysis,
environmental sciences, and economics.

Health, Education, and Social Programs

We also apply our expertise across our full suite of services in the areas of health, education, and social programs.
We believe that a confluence of factors will drive an increased need for public and private focus on these areas, including,
among others:

•

Expanded healthcare services to underserved segments of the population;

Rising healthcare expenditures, which require the evaluation of the effectiveness and efficiency of current and
new programs;

Rampant substance abuse and widespread social and health impacts of the opioid abuse epidemic;

Growing awareness of the threats from the global spread of disease;

The emphasis on improving the effectiveness of the U.S. and other countries’ educational systems;

•

The need for greater transparency and accountability of public sector programs;

A continued high need for social support systems;

The need to recover from natural disasters such as hurricanes, wildfires, and earthquakes;

A changing regulatory environment; and

Military personnel returning home from active duty with health and social service needs.

We believe we are well positioned to provide our services to help our clients develop and manage effective programs
in the areas of health, education, and social programs at the international, regional, national, and local levels. Our subject
matter expertise includes public health, mental health, international health and development, health communications and
associated interactive technologies, education, child and family welfare needs, housing and communities, and substance
abuse. Our combination of domain knowledge and our experience in information technology-based applications provides us
with strong capabilities in health and social programs informatics and analytics, which we believe will be of increasing
importance as the need to manage information grows. We partner with our clients in the government and commercial sectors
to increase their knowledge base, support program development, enhance program operations, evaluate program results, and
improve program effectiveness.

In the area of public health, we support many agencies and programs within the U.S. Department of Health and
Human Services (“HHS”) (including the National Institutes of Health (“NIH”) and the Centers for Disease Control and
Prevention (“CDC”)) by conducting primary data collection and analyses, assisting in designing, delivering and evaluating
programs, managing technical assistance centers, providing instructional systems, developing information technology
applications, and managing information clearinghouse operations. Increasingly, we provide multichannel communications
and messaging for public health programs using capabilities similar to our commercial marketing business. We also provide
training and technical assistance for early care and educational programs (such as Head Start), and health and demographic
surveys in developing countries for the U.S. Department of State (“DOS”). In the area of social programs, we provide
extensive training, technical assistance, and program analysis and support services for a number of the housing and disaster
recovery programs of the U.S. Department of Housing and Urban Development (“HUD”) and state, territorial, and local
governments. In addition, we provide research, program design, evaluation, and training for educational initiatives at the
federal and state level. We provide similar services to a variety of U.K. ministries, as well as several Directorates-General of
the European Commission.

Safety and Security

Safety and security programs continue to be a critical priority of the federal government, state and local governments,
international governments (especially in Europe), and in the commercial sector. We believe we are positioned to meet the
following key safety concerns:

•

Vulnerability of critical infrastructure to cyber and terrorist threats;

Increasing risks to enterprises’ reputations in the wake of a cyber-attack;

Broadened homeland security concerns that include areas such as health, food, energy, water, and transportation;

Reassessment of the emergency management functions of homeland security in the face of natural disasters;

Safety issues around crime and at-risk behavior;

Increased dependence on private sector personnel and organizations in emergency response; and

The need to ensure that critical functions and sectors are resilient and able to recover quickly after attacks or
disasters.

These security concerns create demand for government programs that can identify, prevent, and mitigate key

cybersecurity and the societal issues they cause.

We believe that demand for our services will continue to grow as government, industry, and other stakeholders seek
to address critical long-term societal and natural resource issues due to heightened concerns about: clean energy and energy
efficiency; health promotion, treatment, and cost control; natural disaster relief and rebuild efforts; and ongoing homeland
security threats. In the wake of the major hurricanes (Harvey, Irma, Maria and Michael) that devastated communities in
Texas, Florida, the U.S. Virgin Islands, and Puerto Rico, the affected areas remain in various stages of relief and recovery
efforts. We believe our prior experience with disaster relief and rebuild efforts, including those from Hurricanes Katrina and
Rita and Superstorm Sandy, puts us in a favorable position to provide recovery assistance, housing, and environmental and
infrastructure solutions on behalf of federal departments and agencies, state, territorial and local jurisdictions, and regional
agencies.

In addition, the U.S. Department of Defense (“DoD”) is undergoing major transformations in its approach to
strategies, processes, organizational structures, and business practices due to several complex, long-term factors, including:

•

The changing nature of global security threats, including cybersecurity threats;

Family issues associated with globally-deployed armed forces;

The increasing use of commercial cloud computing infrastructure and services to support the DoD enterprise;
and

The increasing need for real-time information sharing and logistics modernization and network-centric planning
requirements, and the global nature of conflict arenas.

We provide key services to DoD, the U.S. Department of Homeland Security (“DHS”), the U.S. Department of Justice
(“DOJ”), and analogous Directorates-General at the European Commission. We support DoD by providing high-end strategic
planning, analysis, and technology-based solutions in the areas of logistics management, operational support, command and
control, and cybersecurity. We also provide the defense sector with critical infrastructure protection, environmental
management, human capital assessment, military community research, and technology-enabled solutions. At DHS, we assist
in shaping and managing critical programs to ensure the safety of communities, developing critical infrastructure protection
plans and processes, establishing goals and capabilities for national preparedness at all levels of government in the U.S., and
managing the national program to test radiological emergency preparedness at the state and local government levels in
communities adjacent to nuclear power facilities. At DOJ, we provide technical and communications assistance to programs
that help victims of crime and at-risk youths. At the European Commission, we provide support and analytical services related
to justice and home affairs issues within the European context.

Consumer and Financial Markets

In the area of consumer and financial markets, we combine our expertise in strategic communications, marketing and
creative services and public relations with our strengths in interactive and mobile technologies to help companies develop
stronger relationships and engage with their customers and stakeholders across all channels, whether via traditional or digital
media, to drive better operating results. We continue to strengthen our services in the fields of content and customer
relationship management, loyalty marketing, and end-to-end e-commerce. In an effort to enhance our positioning and build
awareness outside of our traditional client set, we have combined capabilities from strategic acquisitions to create a full-
service, technology-rooted advertising agency that guides brands digitally through informed strategy, inspired creative design,
and technical know-how. We have the capability to complete projects big or small across all channels (including web, social,
mobile, intranet and emerging platforms) through end-to-end technology-based implementations for local and global clients.
Target customer areas include airlines, airports, electric and gas utilities, oil companies, banks and other financial services
companies, transportation, travel and hospitality firms, non-profits/associations, law firms, manufacturing firms, retail chains,
and distribution companies.

COMPETITIVE STRENGTHS

We possess the following key business strengths:

We have a highly-educated professional staff with deep subject matter knowledge

We possess strong intellectual capital that provides us with a deep understanding of policies, processes, and programs
across our clients’ markets. Our thought leadership is based on years of training, experience, and education. We are able to
apply our in-depth knowledge of our subject matter experts and our experience developed over 40 years of providing advisory
services to address the problems and issues our clients are facing. As of December 31, 2018, approximately 34% of our
benefits-eligible staff held post-graduate degrees in diverse fields such as the social sciences, business and management,
physical sciences, public policy, human capital, information technology, mathematics, engineering, planning, economics, life
sciences, and law. These qualifications, and the complementary nature of our markets, enable us to deploy multi-disciplinary
teams to identify, develop, and implement solutions that are creative, pragmatic, and tailored to our clients’ specific needs.

We believe our diverse range of client markets, services, and projects provide a stimulating work environment for
our employees that enhances their professional development. The use of multi-disciplinary teams provides our staff the
opportunity to develop and refine common skills required in many types of engagements. Our approach to managing people
fosters collaboration and significant cross-utilization of the skills and experience of both industry experts and other personnel
who can develop creative solutions by drawing on their different experiences. The types of services we provide, and the
manner in which we do so, enable us to attract and retain talented professionals from a variety of backgrounds while
maintaining a culture that fosters teamwork and excellence.

We have strong, long-standing relationships with clients across a diverse set of markets

The long-term relationships we maintain with many of our clients reflect our successful track record of fulfilling our
clients’ needs. We have advised both the U.S. Environmental Protection Agency (“EPA”) and HHS for more than 30 years,
the U.S. Department of Energy (“DOE”) for more than 25 years, DoD for more than 20 years, certain commercial clients in
our energy markets for more than 20 years, the European Commission for more than 15 years, and we have multi-year
relationships with many of our other clients in both our government and commercial client base. We have numerous contacts
at various levels within our clients’ organizations, ranging from key decision-makers to functional managers. The long-
standing nature and breadth of our client relationships adds greatly to our institutional knowledge, which, in turn, helps us
carry out our client engagements more effectively and maintain and expand such relationships. Our extensive experience and
client contacts, together with our prime-contractor position on a substantial majority of our contracts, and experience working
alongside our clients, gives us clearer visibility into future opportunities and emerging requirements. We believe our balance
between government civilian and defense agencies, our commercial presence, and the diversity of markets in which our
clients operate help mitigate the impact of policy or political shifts, as well as annual shifts in our clients’ budgets and
priorities.

Our advisory services position us to capture a full range of engagements

We believe our advisory approach, which is based on our subject matter expertise combined with an understanding
of our clients’ requirements and objectives, is a significant competitive differentiator that helps us gain access to key client
decision-makers during the initial phases of a policy, program, project, or initiative. We use our expertise and understanding
to formulate customized recommendations for our clients. We believe this domain expertise and the program knowledge
developed from our advisory engagements further position us to provide a full suite of services across the entire life cycle of
a particular policy, program, project, or initiative. As a result, we are able to understand our clients’ requirements and
objectives as they evolve over time. We then use this knowledge to provide continuous improvement across our entire range
of services, which maintains the relevance of our recommendations.

Our technology-enabled solutions are driven by our subject matter expertise and creativity

Government and commercial decision-makers have become increasingly aware that, to be effective, technology-
based solutions need to be seamlessly integrated with people and processes. We possess strong knowledge in information
technology and a thorough understanding of organizational behavior and human decision processes. This combination of
skills, along with our domain knowledge, allows us to deliver technology-enabled solutions tailored to our clients’ business
and organizational needs with less start-up time required to understand client issues. In addition, many of our clients seek to
deploy cutting-edge solutions to communicate and transact with citizens, stakeholders, and customers in a multichannel
environment, and doing so takes both our constantly-refreshed technical know-how and world-class creativity.

Our proprietary tools, analytics and methods allow us to deliver superior solutions to our clients

We believe our innovative, and often proprietary, analytics and methods are key competitive differentiators because
they enhance our ability to deliver customized solutions to our clients and enable us to deliver services in a more cost-effective
manner than our competitors. For example, we have developed industry-standard energy and environmental models that are
used by governments and commercial entities around the world for energy planning and air quality analyses and have also
developed a suite of proprietary climate change tools to help the private sector develop strategies for complying with GHG
emission reduction requirements. Our loyalty marketing services are often provided via our proprietary Tally software,
software as a service. We maintain proprietary databases that we continually refine and that are available to be incorporated
quickly into our analyses on client engagements. In addition, we also have proprietary program management methodologies
and services that we believe can help clients improve performance measurement, support chief information officer and science
and engineering program activities, and reduce security risks.

We are led by an experienced management team

Our management team, consisting of approximately 264 officers with the title of vice president or higher, possesses
extensive industry experience and had an average tenure of 13.7 years with us as of December 31, 2018 (including prior
service with companies we have acquired). This low turnover allows us to retain institutional knowledge. Our managers are
experienced both in marketing efforts and in successfully managing and executing our key services. Our management team
also has experience in acquiring other businesses and integrating those operations with our own. A number of our managers
are industry-recognized thought leaders. We believe that our management’s successful past performance and deep
understanding of our clients’ needs have been and will continue to be differentiating factors in competitive situations.

We have a broad global presence

We serve our clients with a global network of more than 65 regional offices throughout the U.S., and more than 15
offices in key markets outside the U.S., including offices in the U.K., Belgium, China, India and Canada. Our global presence
also gives us access to many of the leading experts on a variety of issues from around the world, allowing us to expand our
knowledge base and areas of functional expertise. Over the past year, we worked in dozens of countries, helping government
and commercial clients with energy, environment, infrastructure, healthcare, marketing, interactive technology/e-commerce,
and air transport matters.

STRATEGY

Our strategy to increase our revenue and shareholder value involves the following key elements:

Expand our commercial businesses

We plan to continue to pursue profitable commercial projects and we believe we have strong, global client
relationships in both the commercial energy and air transport markets. We continue to see growth opportunities in our current
commercial business in the utility sector, as well as significant potential for us to expand our business in other commercial
areas, such as aviation and digital marketing services and strategic communications services, both domestically and
internationally.

We view the energy industry as a particularly attractive sector for us over the next decade due to concerns over
controlling energy costs and limiting climate and environmental impacts, increased state and federal regulation, the need for
cleaner and more diverse sources of energy, and the concomitant need for infrastructure to transport, store, and/or convert
those new energy sources. We also believe that the combination of our vertical domain expertise with our digital marketing
expertise makes us a provider of choice for high value-added assignments in that arena. Although we believe the utility
industry will continue to be a strong market for advisory services, particularly in light of the changing focus on regulatory
actions and alternative energy sources, we intend to leverage our existing relationships and institutional expertise to pursue
and capture additional, typically higher-margin opportunities. For example, we believe we can continue to expand our
program and technology-based services in areas such as assisting with the implementation of energy efficiency programs,
information technology applications, and environmental management services for larger utilities. In addition, the growth of
interest in sustainability and energy efficiency issues has created opportunities to offer these types of services to new clients
beyond our traditional sectors. We believe these factors, coupled with our expansive national and global footprint, will result
in a greater number of engagements that will also be larger in size and scope.

We expect that interest in energy advisory services will continue to expand as clients in a number of industries,
including information service providers and companies engaged in travel and tourism, seek to better understand their energy
consumption options and the positive benefits of demonstrating environmental stewardship. Our broad range of services to
the aviation industry makes us well positioned to capitalize on significant industry changes, including substantial airline
equipment upgrades to newer, more efficient aircraft models in a cost-constrained environment; renovations of older airports
to adapt to newer aircraft; and changes to airport business models and strategy as they place increasing importance on
passenger experience.

Our engagement services, including marketing, interactive technology, and strategic communications offerings, are
well-positioned to support the continuing growth of multichannel engagement and e-commerce. We have broadened our
client offerings, particularly in the areas of content management, marketing and digital services. We can now offer complete
end-to-end solutions for chief marketing officers, chief communications officers, and chief technology officers as they invest
in digital marketing platforms and solutions. We deliver cutting-edge digital strategy support, as well as the creative services
that help brands, products and services succeed in a crowded marketplace. As a means of more comprehensively
communicating and delivering our engagement services to customers in both the private and public sectors, ICF recently
announced the creation of ICF Next, an umbrella under which all of ICF’s engagement capabilities can be integrated,
communicated, and delivered to clients.

Replicate our business model across government and industry in selected geographies

We believe the services we provide to our energy, environment, and infrastructure market have strong growth
potential in selected geographies. Our domain expertise is well suited in Europe to meet the need for cutting-edge climate
change, energy and environmental solutions, particularly with our offerings to the U.K. government and European
Commission. We have also focused our geographic footprint, when prudent, by selectively closing or reducing the size of
offices which appear to be unlikely to generate profitable growth in the near to medium term, generally in nations or regions
undergoing either economic or political challenges.

Strengthen our technology-based offerings

We continue to strengthen our services in the fields of content and customer relationship management, loyalty
marketing, and end-to-end e-commerce. We are positioned to increase these services by expanding the technological
underpinnings of our business, while bringing these marketing and e-commerce solutions, as well as expanded data
management and analytics offerings, to our clients to better link them with consumers and other stakeholders.

Leverage advisory work into full life cycle solutions

We plan to continue to leverage our advisory services and strong client relationships to increase our revenue by
winning longer term engagements. These engagements could include: information services and technology-based solutions,
project and program management, business process solutions, marketing and communications delivery, strategic
communications, and technical assistance and training. Our advisory services provide us with insight and understanding of
our clients’ missions and goals. We believe the domain expertise and program knowledge we develop from these advisory
assignments position us to capture a greater portion of the resulting larger engagements. However, we will need to undertake
such expansion carefully to avoid actual, potential, and perceived conflicts of interest.

Defend, expand, and deepen our presence in core U.S. federal and state and local government markets

Changing political priorities at the U.S. federal, state (including territories), and local government levels have created
challenging market conditions for all competitors in the government services sector. We will focus not only on defending our
current market footprint, but also on innovating to continue expanding across key growth markets, such as U.S. federal
government health-related and cybersecurity initiatives, digital services, and disaster recovery work for state and local
governments. We will continue to provide innovative solutions that help our public sector clients do more with less. We will
specifically target deeper penetration of those agencies that currently procure services only from one or two of our service
areas. We believe we can leverage many of our long-term client relationships by introducing these existing clients, where
appropriate, to our other services in order to better meet their needs. For example, we plan to introduce many of our advisory
clients to our capabilities to provide associated information technology, cybersecurity, large-scale program management, and
strategic communications and digital services. We can also offer clients our extensive performance measurement, program
evaluation, and performance management services. Finally, having more than 65 offices across the U.S allows us to focus
more of our business development efforts on addressing the needs of U.S. federal and state and local government agencies
with operations outside of the Washington, D.C. metropolitan area.

Pursue larger prime contract opportunities

We believe that continuing to expand our client engagements into services we offer as part of our end-to-end client
solutions enables us to pursue larger prime contract opportunities, which should provide a greater return on our business
development efforts and allow for increased employee utilization. We plan to continue to target larger and longer-term
opportunities through greater emphasis on early identification of opportunities, strategic capture and positioning, and
enhanced brand recognition. We believe that the resulting increase in the scale, scope, and duration of our contracts will help
us continue to grow our business.

Pursue strategic acquisitions

We plan to augment our organic growth with selective, strategic acquisitions when the target company will enable us
to obtain new clients, increase our presence in attractive markets, and/or obtain capabilities that complement our existing
portfolio of services, provided that the target company has a cultural compatibility and we expect that that the acquisition
will have a positive financial impact.

These elements of our strategy permeate all of the Company and influence day-to-day decisions. We believe that,

collectively, they support the overall long-term growth of the organization.

CLIENT AND CONTRACT MIX

Government clients (including U.S. federal, state (including territories) and local, as well as international,
governments) accounted for approximately 64%, 62%, and 65% of our 2018, 2017, and 2016 revenue,
respectively. Commercial clients (including U.S. and international clients) accounted for approximately 36%, 38%, and 35%
of our 2018, 2017, and 2016 revenue, respectively. Our clients span a broad range of civilian and defense agencies and
commercial enterprises. Commercial clients include non-profit organizations and universities, while government clients
include the World Bank and the United Nations. In general, a client is considered to be a government client if its primary
funding is from a government agency or institution. If we are a subcontractor, we classify the revenue based on the nature of
the ultimate client receiving the services.

In the fiscal years 2018, 2017, and 2016, our three largest clients were HHS, DOS, and DoD. The following table

summarizes the percentage of our total revenue for each of these.

Year ended December 31,

Most of our revenue is derived from prime contracts in which we work directly for the end customer, which accounted

for approximately 92%, 91%, and 90% of our revenue for 2018, 2017, and 2016, respectively.

Our contract periods typically extend from one month to five years, including option periods. Many of our
government contracts provide for option periods that may be exercised by the client. In 2018, 2017, and 2016, no single
contract accounted for more than 4% of our revenue. Our 10 largest contracts by revenue collectively accounted for
approximately 18%, 15%, and 14% of our revenue in 2018, 2017, and 2016, respectively.

International revenues increased by $40.4 million for the year ended December 31, 2018 compared to the year ended
December 31, 2017, as a result of both organic growth and growth through acquisitions, due to increases in our international
government client services in the energy, environment and infrastructure and in the health, education, and social program
client markets and increases in our international commercial client services in the consumer and financial client markets.

CONTRACT BACKLOG

We define total backlog as the future revenue we expect to receive from our contracts and other engagements. We
generally include in our total backlog the estimated revenue represented by contract options that have been priced, but not
exercised. We do not include any estimate of revenue relating to potential future delivery orders that might be awarded under
our U.S. General Services Administration Multiple Award Schedule (“GSA Schedule”) contracts, other Indefinite
Delivery/Indefinite Quantity (“IDIQ”) contracts, Master Service Agreements (“MSAs”), or other contract vehicles that are
also held by a large number of firms and under which potential future delivery orders or task orders might be issued by any
of a large number of different agencies, and are likely to be subject to a competitive bidding process. We do, however, include
potential future work expected to be awarded under IDIQ contracts that are available to be utilized by a limited number of
potential clients and are held either by us alone or by a limited number of firms.

We include expected revenue in funded backlog when we have been authorized by the client to proceed under a
contract up to the dollar amount specified by our client, and this amount will be owed to us under the contract after we provide
the services pursuant to the authorization. If we do not provide services authorized by a client prior to the expiration of the
authorization, we remove amounts corresponding to the expired authorization from funded backlog. We do include expected
revenue under an engagement in funded backlog when we do not have a signed contract, but only in situations when we have
received client authorization to begin or continue working and we expect to sign a contract for the engagement. In this case,
the amount of funded backlog is limited to the amount authorized. Our funded backlog does not represent the full revenue
potential of our contracts because many government clients, and sometimes other clients, authorize work under a particular
contract on a yearly or more frequent basis, even though the contract may extend over several years. Most of the services we
provide to commercial clients are provided under contracts or task orders under MSAs with relatively short durations. As a
consequence, our backlog attributable to these clients is typically reflected in funded backlog and not in unfunded backlog.

We define unfunded backlog as the difference between total backlog and funded backlog. Our estimate of unfunded
backlog for a particular contract is based, to a large extent, on the amount of revenue we have recently recognized on the
particular contract under the assumption that future utilization will be similar, our past experience in utilizing contract
capacity on similar types of contracts, and our professional judgment. Accordingly, if contract utilization is different from
our expectations, the revenue eventually earned on a contract may be lower or higher than that implied by our estimate, at a
point in time or during the life of a contract, of total backlog, including unfunded backlog. Although we expect our total
backlog to result in revenue, the timing of revenue associated with both funded and unfunded backlog will vary based on a
number of factors, and we may not recognize revenue associated with a particular component of backlog when anticipated,
or at all. Our government clients generally have the right to cancel any contract, or ongoing or planned work under any
contract, at any time. In addition, there can be no assurance that revenue from funded or unfunded backlog will have similar
profitability to previous work or will be profitable at all. Generally speaking, we believe the risk that a particular component
of backlog will not result in future revenue is higher for unfunded backlog than for funded backlog.

Our funded and estimates of unfunded and total backlog were as follows at December 31:

Funded .................................................................................................... $
Unfunded ................................................................................................
Total backlog ....................................................................................... $

1,140.1 $

1,950.4 $

1,020.3

There were no awards included in our 2018, 2017 or 2016 backlog amounts that were under protest.

BUSINESS DEVELOPMENT

Our business development efforts are critical to our organic growth. Our business development processes and systems
are designed to enable agility and speed-to-market over the business development life cycle, especially given the distinctions
between commercial and government clients. Business development efforts in priority market areas, which include some of
our largest federal agency accounts (HHS, DOS, DOE, U.S. Department of Transportation and EPA), are executed through
account teams, each of which is headed by a corporate account executive and supported by dedicated corporate business
development professionals and senior staff from the relevant operational area. Each account executive has significant
authority and accountability to set priorities, focusing on larger and strategically important pursuits, and utilize appropriate
resources to win new work. Each team participates in regular executive reviews of marketing plans and proposal development
process. Our non-federal government clients are served by account leaders from operating units and coordinated by senior
executives with industry experience where such coordination is deemed appropriate to enhance our business development
success. This account-based approach allows deep insight into the needs of current and future clients. It also helps us
anticipate our clients’ evolving requirements over the coming 12 to 18 months and position ourselves to meet those
requirements. Each administrative group is responsible for maximizing sales in our existing accounts and finding
opportunities in closely-related accounts.

The corporate business development function also includes a market research and competitive intelligence group, a
proposal group, a marketing group, a communications group, and a strategic capture unit. The marketing group engages in
brand marketing and strategic marketing program development and execution to raise awareness of our services and solutions
across our markets, and to generate leads for further pursuit by sales personnel. Our contracts and administration function
supports bid price development in partnership with the business development account teams.

COMPETITION

We operate in a highly competitive and fragmented marketplace and compete against a number of firms in each of
our clients’ key markets. Some of our principal competitors include: Abt Associates Inc.; AECOM Technology Corporation;
Alliance Data Systems Corporation; Booz Allen Hamilton Holding Corporation; CACI International Inc.; Cambridge
Systematics, Inc.; CRA International, Inc.; Deloitte LLP; Eastern Research Group, Inc.; Cardno ENTRIX, Inc.; L-3
Technologies, Inc.; Leidos Holdings, Inc.; Lockheed Martin Corporation; ManTech International Corporation; Navigant
Consulting, Inc.; Northrop Grumman Corporation; Omnicom Group Inc.; PA Consulting Group; PricewaterhouseCoopers
(PwC); Publicis Group; Science Applications International Corp; Research Triangle Institute; Tetra Tech Inc.; Westat, Inc.,
and WPP Plc. In addition, we have numerous smaller competitors, many of which have narrower service offerings and serve
niche markets. Some of our competitors are significantly larger than we are and have greater access to resources and stronger
brand recognition than we do.

We consider our principal competitive discriminators to be long-standing client relationships, good reputation and
past performance of the firm, client references, technical knowledge and industry expertise of employees, quality of services
and solutions, scope and scale of our service offerings, and pricing.

INTELLECTUAL PROPERTY

We own a number of trademarks and copyrights that help maintain our business and competitive position. Sales and
licenses of our intellectual property do not currently comprise a substantial portion of our revenue or profit. We rely on the
technology and models, proprietary processes, and other intellectual property we own or have rights to use in our analyses
and other work we perform for our clients. We use these innovative, and often proprietary, software, analytical models and
tools throughout our service offerings. Our staff regularly maintains, updates, and improves these software, models, and tools
based on our corporate experience. In addition, we sometimes retain limited rights in software applications we develop for
clients. We use a variety of means to protect our intellectual property.

EMPLOYEES

As of December 31, 2018, we had more than 6,000 benefits-eligible (full-time or benefits eligible) employees,
approximately 34% of whom held post-graduate degrees in diverse fields such as social sciences, business and management,
physical sciences, public policy, human capital, information technology and mathematics, engineering, planning, economics,
life sciences, and law. Approximately 80% of our employees held a bachelor’s degree or equivalent or higher. Our
professional environment encourages advanced training to acquire industry-recognized certifications, rewards strong job
performance with advancement opportunities, and fosters ethical and honest conduct. Our salary structure, incentive
compensation, and benefit packages are competitive within our industry.

ITEM 1A. RISK FACTORS

The following discussion of “risk factors” sets forth some of the most significant factors that may adversely affect
our business, operations, financial position or future financial performance, reputation and/or value of our stock. This
information should be read in conjunction with Management’s Discussion and Analysis and the consolidated financial
statements and related notes incorporated by reference into this Annual Report on Form 10-K. Because of the following
factors, as well as other factors, whether known or unknown, affecting our business, operations, financial position or future
financial performance, reputation and/or value of our stock, past financial performance should not be considered to be a
reliable indicator of future performance, and investors should not use historical trends to anticipate results or trends in future
periods.

RISKS RELATED TO OUR INDUSTRY

The failure of Congress to approve appropriations bills in a timely manner for the federal government agencies and
departments we support, or the failure of the Administration and Congress to reach an agreement on fiscal issues,
could delay and reduce spending, cause us to lose revenue and profit, and affect our cash flow.

On an annual basis, Congress is required to approve appropriations bills that govern spending by each of the federal
government agencies and departments we support. When Congress is, or Congress and the Administration are, unable to
agree on budget priorities, and thus unable to pass annual appropriations bills on a timely basis, Congress typically enacts a
continuing resolution. Continuing resolutions generally allow federal government agencies and departments to operate at
spending levels based on the previous fiscal year. When agencies and departments operate on the basis of a continuing
resolution, funding we expect to receive from clients for work we are already performing and for new initiatives may be
delayed or cancelled. Recently Congress and the Administration have failed to agree on a continuing resolution, resulting in
a temporary shutdown of non-essential federal government functions and our work on such functions. Thus, the failure by
Congress and the Administration to approve appropriations bills in a timely manner can result in the loss of revenue and
profit when federal government agencies and departments are required to cancel or change existing or new initiatives or the
deferral of revenue and profit to later periods due to shutdowns or delays in implementing existing or new initiatives. There
is also the possibility that Congress will fail to raise the U.S. debt ceiling when necessary. This can also result in federal
government shutdowns. The delayed funding or shutdown of many parts of the federal government, including agencies,
departments, programs, and projects we support could have a substantial negative affect on our revenue, profit, and cash
flows. The budgets of many of our state and local government clients are also subject to similar processes, and, as a result,
subject us to similar risks and uncertainties.

In addition, in an effort to control the federal government deficit, Congress passed the Budget Control Act of 2011
(the “Budget Act”), which mandated the reduction of discretionary spending by the federal government by $1.2 trillion over
10 years. While some of these reductions have been rescinded and certain spending caps were raised for Fiscal Years 2018
and 2019, the spending caps for Fiscal Years 2020 and 2021 remain in place and, unless they are also rescinded, could
continue to constrain federal discretionary spending for the services we provide. Because we derive a significant portion of
our revenue from contracts with federal government clients, a decline in federal government expenditures and/or a shift of
expenditures away from programs in which we provide support, whether as a result of the Budget Act or otherwise, would
likely have a negative impact on our business and results.

Government budgeting and spending priorities may change in a manner adverse to our business.

We derived approximately 41%, 45%, and 48% of our revenue in 2018, 2017, and 2016, respectively, from contracts
with federal government clients, and approximately 23%, 17%, and 17% of our revenue from contracts with state and local
governments and international governments in 2018, 2017, and 2016, respectively. Expenditures by our federal government
clients may be restricted or reduced by presidential or congressional actions, by action of the Office of Management and
Budget, by action of individual agencies or departments, or by other actions. In addition, many state and local governments
are not permitted to operate with budget deficits and nearly all state and local governments face considerable challenges in
balancing their budgets. Accordingly, we expect, due to changing government budgeting and spending priorities, that some
of our government clients in the future may delay payments due to us, may eventually fail to pay what they owe us, and/or
may delay certain programs and projects. For some government clients, we may face a difficult choice: turn down (or stop)
work due to budget uncertainty with the risk of damaging a valuable client relationship or perform work with the risk of not
being paid in a timely fashion or perhaps at all. Federal and/or state and local government elections could also affect spending
priorities and budgets at all levels of government. In addition, increased deficits and debt at all levels of government, both
domestic and international, may lead to reduced spending by agencies and departments on projects or programs we support.

Our failure to comply with complex laws, rules, and regulations could cause us to lose business and subject us to a
variety of penalties and sanctions.

We must comply with laws, rules, and regulations that affect how we do business with our government clients and
impose added costs on our business. Each government client has its own laws, rules, and regulations that affect its contracts.
Some of the more significant laws and regulations affecting the formation, administration, and performance of U.S.
government contracts include:

•

U.S. Federal Acquisition Regulation as well as Cost Accounting Standards, and agency and department
regulations analogous or supplemental to federal regulation;

U.S. Foreign Corrupt Practices Act;

U.S. Truthful Cost or Pricing Data Act (formerly known as the Truth in Negotiations Act);

U.S. Procurement Integrity Act;

U.S. Civil False Claims Act and the False Statements Act; and

U.S. laws, rules and regulations restricting (i) the use and dissemination of information classified for national
security purposes, (ii) the exportation of specified products, technologies, and technical data, and (iii) the use
and dissemination of sensitive but unclassified data.

Any failure to comply with applicable federal, and/or state and local government laws, rules and regulations could
subject us to civil and criminal penalties and administrative sanctions, including termination of contracts, repayment of
amounts already received under contracts, forfeiture of profits, suspension of payments, fines, and suspension or debarment
from doing business with federal and/or state and local government agencies and departments, any of which could adversely
affect our reputation, our revenue, our operating results, and/or the value of our stock.

In addition, the federal government and other governments with which we do business may change their procurement
practices or adopt new contracting laws, rules, or regulations that could be costly to satisfy or that could impair our ability to
obtain new contracts and reduce our revenue and profit, such as curtailing the use of services firms or increasing the use of
firms with a “preferred status,” such as small businesses.

In addition to our U.S. operations, we also have a significant presence in key markets outside the U.S., including
offices in the U.K., Belgium, China, India and Canada. Failure to abide by laws, rules and regulations applicable to us because
of our work outside the U.S., such as the U.K. Bribery Act and European Union’s General Data Protection Regulation, could
have similar effects to those described above.

We are subject to various routine and non-routine governmental and other reviews, audits and investigations, and
unfavorable results could force us to adjust previously reported operating results, could affect future operating
results, and could subject us to a variety of penalties and sanctions.

Federal government departments and agencies and many state, territorial and local government clients review, audit
and investigate our contract performance, pricing practices, cost structure, financial capability, and compliance with
applicable laws, rules, and regulations. We have experienced growth in services related to disaster recovery in recent years,
and those activities, by their nature, may involve interaction with a combination of federal, state, territorial and local
governments, citizens and subcontractors that increase the risk of audits, investigations, reviews, monitoring and
litigation. Any of these reviews, audits and investigations could raise issues that have significant adverse effects, including,
but not limited to, substantial adjustments to our previously reported operating results and substantial effects on future
operating results. If a government review, audit, or investigation uncovers improper or illegal activities, we may be subject
to civil and criminal penalties and administrative sanctions, including termination of contracts, repayment of amounts already
received under contracts, forfeiture of profits, suspension of payments, fines, and suspension or debarment from doing
business with federal and state and local government agencies and departments, any of which could adversely affect our
reputation, our revenue, our operating results, and/or the value of our stock. We may also lose business if we are found not
to be sufficiently able to meet ongoing cash flow and financial obligations on a timely basis. In addition, we could suffer
serious harm to our reputation and our stock price could decline if allegations of impropriety are made against us, whether
true or not. Federal government audits have been completed on our incurred contract costs only through 2010 and audits for
costs incurred on work performed since then have not yet been completed. In addition, non-audit reviews by federal and state
and local governments may still be conducted on all our government contracts, even for periods before 2010.

Our contracts may contain provisions that are unfavorable to us and permit our clients to, among other things,
terminate our contracts partially or completely at any time prior to completion.

Our contracts may contain provisions that allow our clients to terminate or modify these contracts at their convenience
on short notice. If a client terminates one of our contracts for convenience, we may only bill the client for work completed
prior to the termination, plus any commitments and settlement expenses the client agrees to pay, but not for any work not yet
performed. In addition, many of our government contracts and task and delivery orders are incrementally funded as
appropriated funds become available. The reduction or elimination of such funding can result in contract options not being
exercised and further work on existing contracts and orders being curtailed. In any such event, we would have no right to
seek lost fees or other damages. In addition, certain contracts with international government clients may have more severe
and/or different contract clauses than what we are accustomed to with federal and state and local government clients, such as
penalties for any delay in performance. If a client were to terminate, decline to exercise options under, or curtail further
performance under one or more of our major contracts, our revenue and operating results could be adversely affected.

Our commercial work depends on certain sectors of the global economy that are highly cyclical, which can lead to
substantial variations in our revenue and profit from period to period.

In recent years, we have expanded our work with commercial clients. Our commercial clients, which include clients
outside the U.S., generated approximately 36%, 38%, and 35% of our revenue in 2018, 2017, and 2016, respectively. This
increased reliance on commercial clients presents new risks and challenges. For example, our commercial work is heavily
concentrated in industries which can be cyclical, such as: energy, air transportation, environmental, health, retail and financial
services. Demand for our services from our commercial clients has historically declined when their industries have
experienced downturns, and we expect a decline in demand for our services when these industries experience downturns in
the future.

As we expand our national and global footprint, we may become involved in a greater number of engagements that
will be larger in size and scope. The increase in size and scope of the engagements in which we become involved in subjects
us to the potential for a larger impact of a change in the credit risk associated with certain larger customers, particularly
among our commercial clients. Our customers may face unexpected circumstances that adversely impact their ability to pay
their trade payables to us and we may face unexpected losses as a result. Such circumstances could lead to the customer filing
for bankruptcy. This can ultimately lead to variations in our profit from period to period. We monitor the aging of receivables
regularly and make assessments of the ability of customers to pay amounts due.

RISKS RELATED TO OUR BUSINESS

Changes to U.S. tax laws may adversely affect our financial condition or results of operation and create the risk that
we may need to adjust our accounting for these changes.

The Tax Cuts and Jobs Act (the “Tax Act”), enacted in late 2017, made significant changes to U.S. tax laws and
included numerous provisions that affect businesses, including ours. For instance, as a result of lower corporate tax rates, the
Tax Act tends to reduce both the value of deferred tax assets and the amount of deferred tax liabilities. It also limits interest
rate deductions and the amount of net operating losses that can be used each year and alters the expensing of capital
expenditures. Other provisions have international tax consequences for businesses like ours that operate internationally. The
Tax Act is unclear in certain respects and will require interpretations and implementing regulations by the Internal Revenue
Service, as well as state tax authorities, and the Tax Act could be subject to amendments and technical corrections, any of
which could lessen or increase the adverse (and positive) impacts of the Tax Act. The accounting treatment of these tax law
changes is complex, and some of the changes may affect both current and future periods. Others will primarily affect future
periods.

Maintaining our client relationships and professional reputation are critical to our ability to successfully win new
contracts and renew expired contracts.

Our client relationships and professional reputation are key factors in maintaining and growing our business, revenue
and profit levels under contracts with our clients. We continually bid for and execute new contracts, and our existing contracts
continually become subject to re-competition and expiration. If we are not able to replace the revenue from these contracts,
either through follow-on contracts or new contracts for those requirements or for other requirements, our revenue and
operating results may be adversely affected. On the expiration of a contract, we typically seek a new contract or subcontractor
role relating to that client to replace the revenue generated by the expired contract. There can be no assurance that those
expiring contracts we are servicing will continue after their expiration, that the client will re-procure those requirements, that
any such re-procurement will not be restricted in a way that would eliminate us from the competition (e.g. set asides for small
businesses), or that we will be successful in any such re-procurements or in obtaining subcontractor roles. Any factor that
diminishes client relationships and/or professional reputation with federal, state, territorial and local and international
government clients, as well as commercial clients, could make it substantially more difficult for us to compete successfully
for new engagements and qualified employees. To the extent our client relationships and/or professional reputation
deteriorate, our revenue and operating results could be adversely affected.

Our reliance on GSA Schedule and other IDIQ contracts creates the risk of volatility in our revenue and profit levels.

We believe that one of the elements of our success is our position as a prime contractor under GSA Schedule contracts
and other IDIQ contracts and we believe this position is important to our ability to sell our services to federal government
clients. However, these contract vehicles require us to compete for each delivery order and task order, rather than having a
more predictable stream of activity during the term of a multi-year contract. In addition, we may spend considerable cost and
managerial time and effort to prepare bids and proposals for contracts, delivery orders or task orders that we may not win.
There can be no assurance that we will continue to obtain revenue from such contracts at current levels, or in any amount, in
the future. To the extent that federal government agencies and departments choose to employ GSA Schedule contracts and
other IDIQ contracts encompassing activities for which we are not able to compete or provide services, we could lose
business, which would negatively affect our revenue and profitability.

We may not receive revenue corresponding to the full amount of our backlog, or may receive it later than we expect,
which could adversely affect our revenue and operating results.

The calculation of backlog is highly subjective and conditioned on numerous uncertainties and estimates, and there
can be no assurance that we will in fact receive the amounts we have included in our backlog. Our assessment of a contract’s
potential value is based on factors such as the amount of revenue we have recently recognized on that contract under the
assumption that future utilization will be similar, our experience in utilizing contract capacity on similar types of contracts,
and our professional judgment. In the case of contracts that may be renewed at the option of the client, we generally calculate
backlog by assuming that the client will exercise all of its renewal options; however, the client may elect not to do so. In
addition, federal government contracts rely on congressional appropriation of funding, which is typically provided only
partially at any point during the term of federal government contracts, and all or some of the work to be performed under a
contract may require future appropriations by Congress and the subsequent allocation of funding by the procuring agency or
department to the contract. Protests of contracts continue to be common in our industry. We do not include contract awards
that are subject to a pending protest in our calculation of backlog. If a contract previously included in backlog becomes the
subject of a protest, we would adjust backlog to remove that amount and reassess following resolution of the protest. Our
estimate of the portion of backlog that we expect to recognize as revenue in any future period may differ from actual results
because the receipt and timing of this revenue often depends on subsequent appropriation and allocation of funding and is
subject to various contingencies, such as timing of task orders and delivery orders, many of which are beyond our control. In
addition, we may never receive revenue from some of the engagements that are included in our backlog, and this risk is
greater with respect to unfunded backlog. Although we adjust our backlog to reflect modifications to or renewals of existing
contracts, awards of new contracts, or approvals of expenditures, if we subsequently fail to realize revenue corresponding to
our backlog, our revenue and operating results could be adversely affected.

Failure to identify, hire, train and retain talented employees who are committed to our mission and vision could have
a negative effect on our reputation and our business.

Our business, which entails the provision of professional services to government and commercial clients, largely
depends on our ability to attract and retain qualified employees. Additionally, as our business continues to evolve, as we
acquire new businesses, and as we provide a wider range of services, we become increasingly dependent on the capabilities
of our employees in order to meet the needs of our diverse client base. If we are unable to recruit and retain a sufficient
number of qualified employees that are committed to our mission and vision, we may incur higher costs related to an increase
in subcontractors, hiring, training and retention. Effective succession planning is also important to our long-term success.
Failure to ensure effective transfer of knowledge and smooth transitions involving key employees could hinder our strategic
planning and execution. Additionally, the loss of key personnel could impair our ability to effectively serve our clients and
maintain and grow our business, and our future revenue and operating results could be adversely affected.

Because much of our work is performed under task orders and delivery orders and, on certain occasions, other short-
term assignments, we are exposed to the risk of not having sufficient work for our staff, which can affect revenue and
profit.

We perform some of our work under short-term contracts. Even under many of our longer-term contracts, we perform
much of our work under individual task orders and delivery orders, many of which are awarded on a competitive basis. If we
cannot obtain new work in a timely fashion, whether through new contracts, task orders, or delivery orders, modifications to
existing contracts, or otherwise, we may not be able to keep our staff profitably utilized, which may result in challenges
related to retaining talented members of our staff and also adversely impact our financial results. There can be no assurance
that we can profitably manage the utilization of, or retain, our staff.

If we are unable to accurately estimate and control our contract costs, then we may incur losses on our contracts,
which could decrease our operating margins and reduce our profits. In particular, the unpredictability of our earnings
could increase on our fixed-price contracts if we cannot accurately estimate and control our contract costs.

It is important for us to accurately estimate and control our contract costs so that we can maintain positive operating
margins and profitability. As described elsewhere in this Form 10-K, we generally enter into three principal types of contracts
with our clients: fixed-price, time-and-materials and cost-plus.

We derived 39%, 39%, and 39% of our revenue from fixed-price contracts 2018, 2017, and 2016, respectively. Under
fixed-price contracts, we receive a fixed price irrespective of the actual costs we incur and, consequently, we are exposed to
a number of risks. We realize a profit on fixed-price contracts only if we can control our costs and prevent cost overruns
while also meeting contract requirements. Fixed-price contracts require cost and scheduling estimates that are based on a
number of assumptions, including those about future economic conditions, costs, and availability of labor, equipment and
materials, and other exigencies. We could experience cost overruns if these estimates are inaccurate as a result of errors or
ambiguities in the contract specifications, or become inaccurate as a result of a change in circumstances following the
submission of the estimate due to, among other things, unanticipated technical problems, difficulties in obtaining permits or
approvals, changes in local laws or labor conditions, weather delays, or the inability of our vendors or subcontractors to
perform. If cost overruns occur, we could experience reduced profits or, in some cases, a loss for that project. If a project is
significant, or if there are one or more common issues that impact multiple projects, costs overruns could increase the
unpredictability of our earnings, as well as have an adverse impact on our business and earnings.

We provide digital marketing services in highly competitive and constantly evolving markets. Our success in these
markets depends on our ability to develop and integrate new technologies into our business and enhance our existing
products and services, as well as our ability to respond to rapid changes in technology in order to remain competitive.

In our consumer and financial market, we provide digital marketing services in highly competitive markets. We
compete principally with large systems consulting and implementation firms, traditional and digital advertising and marketing
agencies, offshore consulting and outsourcing companies, and clients’ internal information systems departments. To a lesser
extent, other competitors include boutique consulting firms that maintain specialized skills and/or are geographically focused.
We expect these competitors to devote significant effort to maintaining and growing their respective market shares. If we
cannot respond effectively to advances by our competitors in this market, or grow our own business efficiently, our overall
business and operating results could be adversely affected.

Our success in this competitive market depends in part on our ability to adapt to rapid technological advances and
evolving standards in computer and mobile device hardware and software development and media infrastructure, changing
and increasingly sophisticated customer needs, newly-developed digital marketing services and platform introductions and
enhancements. If, within this market, we are unable to develop new or sufficiently differentiated products and services, to
enhance and improve our products and support services in a timely manner or to position and/or price our products and
services to meet demand, our overall business and operating results could be adversely affected.

Litigation, claims, disputes, audits, reviews, and investigations in connection with the completed Road Home contract
expose us to many different types of liability, may divert management attention, and could increase our costs.

In June 2006, our subsidiary, ICF Emergency Management Services, LLC (“ICF Emergency”), was awarded the
Road Home contract by the State of Louisiana, Office of Community Development (the “OCD”), to manage a program
designed primarily to help homeowners and landlords of small rental properties affected by Hurricanes Rita and Katrina by
providing them compensation for the uninsured, uncompensated damages they suffered from the hurricanes (the “Program”).
With an aggregate value of $912 million, the Road Home contract was our largest contract throughout its three-year duration,
which ended on June 11, 2009.

The Road Home contract provided us with significant opportunities, but also created substantial risks. A number of
these risks continued beyond the term of the contract. We still have lawsuits pending, and other claims have been made
against us in connection with this contract. New lawsuits may be filed, and new claims may be made against us in the future
including, but not limited to, claims by subcontractors and others who are dissatisfied with the amount of money they have
received from, or their treatment under, the Program. We have defended such lawsuits and claims vigorously and plan to
continue to do so, but we may not prevail in future cases. Although the contract provides that, with several exceptions, we
are allowed to charge, as an expense under the contract, reasonable costs and fees incurred in defending and paying claims
brought by third parties arising out of our performance, there can be no assurance that our legal costs and fees will be
reimbursed. The State of Louisiana has not reimbursed us for the majority of such costs or fees and has not reimbursed any
such costs or fees since 2008. The outstanding contract receivables related to defending and paying claims were fully reserved
as of December 31, 2018.

In addition, as discussed in “Note 19—Commitments and Contingencies – Road Home Contract” in our financial
statements, on June 10, 2016, the OCD filed a written administrative demand (the “Administrative Demand”) with the
Louisiana Commissioner of Administration against ICF Emergency in connection with the administration of the Program. In
its administrative demand, the OCD sought approximately $200.8 million in alleged overpayments to Program grant
recipients. The OCD separately supplemented the amount of recovery it is seeking in total approximately $220.2 million. The
State of Louisiana, through the Division of Administration, also filed suit (the “Proceeding”) in Louisiana state court on June
10, 2016 broadly alleging and seeking recoupment for the same claim made in the Administrative Demand. On September
21, 2016, the Commissioner of the Division of Administration notified the OCD and the Company of his decision to defer
jurisdiction of the Administrative Demand. In so doing, the Commissioner declined to reach a decision on the merits, stated
that his deferral would not be deemed to grant or deny any portion of the OCD’s claim, and authorized the parties to proceed
on the matter in the Proceeding. The Company continues to believe that neither the Administrative Demand nor the
Proceeding has any merit, intends to vigorously defend its position, and has therefore not recorded a liability as of
December 31, 2018.

As discussed above, the Road Home contract has been, and may continue to be, the subject of audit, investigations,
and reviews by federal and state government authorities and their representatives. These activities may consume significant
management time and effort. Further, the contract provides that we are subject to audits for a period after the date of the last
payment made under the contract. Findings from any audit, investigation, review, monitoring, or similar activity could subject
us to civil and criminal penalties and administrative sanctions from federal and state government authorities, which could
substantially adversely affect our reputation, our revenue, our operating results, and the value of our stock.

We derive significant revenue and profit from contracts awarded through a competitive bidding process, which can
impose substantial costs on us, and we will lose revenue and profit if we fail to compete effectively.

We derive significant revenue and profit from contracts that are awarded through a competitive bidding process.

Competitive bidding imposes substantial costs and presents a number of risks, including the:

•

Substantial cost and managerial time and effort that we spend to prepare bids and proposals;

Need to estimate accurately the resources and costs that will be required to service any contracts we are awarded,
sometimes in advance of the final determination of their full scope;

Expense and delay that may arise if our competitors protest or challenge awards made to us pursuant to
competitive bidding, as discussed in the risk factor below; and

Opportunity cost of not bidding on and winning other contracts we may have otherwise pursued.

To the extent we engage in competitive bidding and are unable to win particular contracts, we not only incur
substantial costs in the bidding process that negatively affect our operating results, but we may lose the opportunity to operate
in the market for the services provided under those contracts for a number of years. Even if we win a particular contract
through competitive bidding, our profit margins may be depressed or we may even suffer losses as a result of the costs
incurred through the bidding process and the need to lower our prices to overcome competition.

Our business could be adversely affected by delays caused by our competitors protesting contract awards received by
us, which could stop our work. Likewise, we may protest the contracts awarded to some of our competitors, a process
that takes the time and energy of our management and we may incur additional legal and consultant costs.

Due in part to the competitive bidding process under which government contracts are awarded, we are at risk of
incurring expenses and delays if one or more of our competitors protest contracts awarded to us. Contract protests remain
common in our industry and may result in a requirement to resubmit offers for the protested contract or in the termination,
reduction, or modification of the awarded contract. It can take many months to resolve contract protests and, in the interim,
the contracting government agency or department may suspend our performance under the contract pending the outcome of
the protest. Even if we prevail in defending the contract award, the resulting delay in the startup and funding of the work
under these contracts may adversely affect our operating results.

Moreover, in order to protect our competitive position, we may protest the contract awards of our competitors. This
process takes the time and energy of our executives and employees, is likely to divert management’s attention from other
important matters and could cause us to incur additional legal and consultant costs.

Our international operations pose additional risks to our profitability and operating results.

We have offices in the U.K., Belgium, China, India and Canada, among others, and expect to continue to have
international operations and offices, some of which are in underdeveloped countries that do not have a well-established
business infrastructure. We also perform work in some countries where we do not have a physical office. Some of the
countries in which we work have a history of political instability or may expose our employees and subcontractors to physical
danger. Expansion into selective new geographic regions requires considerable management and financial resources, the
expenditure of which may negatively impact our results, and we may never see any return on our investment.

Our international operations are subject to risks associated with operating in, and selling to and in, countries other
than the U.S., that could, directly or indirectly, adversely affect our international and domestic operations and our overall
revenue, profit, and operating results including, but not limited to:

•

Compliance with the laws, rules, regulations, policies, legal standards, and enforcement mechanisms of the U.S.
and the other countries in which we operate, including bribery and anti-corruption laws, economic sanctions,
trade restrictions, local tax and income laws, and local labor and employment laws, which are sometimes
inconsistent;

Restrictions on the ability to repatriate profits to the U.S. or otherwise move funds;

Potential personal injury to personnel who may be exposed to military conflicts and other hostile situations in
foreign countries;

Expropriation and nationalization of our assets or those of our subcontractors, and other inabilities to protect our
property rights; and/or

Difficulties in managing and staffing such operations, including obtaining work permits or visas, identifying
qualified local employees, operating according to different local labor laws and regulations, dealing with
different local business cultures and practices, and collecting contract receivables.

In addition, because of our work with international clients, certain of our revenues and costs are denominated in other
currencies, then translated to U.S. dollars for financial reporting purposes. Our revenues and profits may decrease as a result
of currency fluctuations and devaluations and limitations on the conversion of foreign currencies into U.S. dollars and in the
conversion between foreign currencies. We currently have forward contract agreements (“hedges”) related to our operations
in the E.U. hedging the translation between the Euro and the pound sterling. We recognize changes in the fair-value of the
hedges in our results of operations. We may increase the number, size and scope of our hedges as we analyze options for
mitigating our foreign exchange risk. We cannot be sure that our hedges will be successful in reducing the risks to us of our
exposure to foreign currency fluctuations and, in fact, the hedges may adversely affect our operating results.

Our business in the U.K. and the European Union could be negatively affected by the timing and terms of, and
uncertainties related to, the U.K.’s exit, and potential other exits, from the European Union.

Geopolitical events in the European Union ("E.U.") may adversely impact our business. On June 23, 2016 voters in
the U.K. approved an exit from the E.U. On March 29, 2017 the U.K. initiated the process under Article 50 of the Treaty on
the European Union, commencing a period of up to two years for the E.U. and other E.U. member states to negotiate with the
U.K. the terms of a withdrawal (often referred to as “Brexit”). Such an exit from the E.U. is unprecedented, and it is still
unclear how the U.K.’s access to the E.U. Single Market, and the wider commercial, legal and regulatory environment in
which we, our customers and our counterparties operate, will be impacted. Our U.K. and Belgian operations have
traditionally serviced most of our European clients, including the E.U., and these operations could be disrupted by Brexit,
particularly if there is a change in the U.K.’s relationship to the E.U. Single Market. Completion of a so-called “hard/ no-deal
Brexit,” whereby the U.K. exits the E.U. with no negotiated market access or agreements on issues such as customs and
citizen mobility, would likely cause economic, logistical, and legal disruptions, any or all of which could adversely affect our
operations and financial results. Such an event, potentially driven by Parliament’s failure to approve Prime Minister May’s
negotiated Brexit plan, could also induce other actions, such as further movement towards secession from the U.K. by
Scotland or other elements of the U.K., with different but significant negative consequences. It is also possible that the U.K.
and E.U. will agree to extend the deadline for withdrawal, thus extending the uncertainty. The uncertainties surrounding the
timing and terms of the U.K.’s exit and its consequences could adversely impact customer and investor confidence, result in
additional market volatility and adversely affect our businesses and results of operations. These impacts could derive from
delays or reductions in contract awards, canceled contracts, changes in exchange rates, difficulty in recruiting or in gaining
permission to employ existing staff, or less favorable payment terms.

Other member states or portions thereof may conduct similar referenda leading to an exit from the E.U. or demands
for greater freedom from the strictures deriving from the E.U., resulting in a reduction in funding for the European
Commission that could lead to a decrease in the funding and scope of our work for that client. In addition, security and
sovereignty and financial system stability issues resulting from geopolitical events, or the E.U. negotiations driven by those
events, could change the current balance of responsibility established between the European Commission and member
nations, or affect the results of the E.U. budget-setting process, either of which could also reduce the funding and scope of
our work for that client.

As we develop new services, clients and practices, enter new lines of business, and focus more of our business on
providing a full range of client solutions, our operating risks increase.

As part of our corporate strategy, we are attempting to leverage our advisory services to sell our full suite of services
across the life cycle of a policy, program, project, or initiative, and we are regularly searching for ways to provide new
services to clients. In addition, we plan to extend our services to new clients, into new lines of business, and into new selected
geographic locations. As we focus more on our delivery of a full range of consulting services from advisory through
implementation and attempt to develop new services, clients, practice areas and lines of business these efforts could be
unsuccessful and adversely affect our results of operations.

Such growth efforts place substantial additional demands on our management and staff, as well as on our information,
financial, administrative and operational systems. We may not be able to manage these demands successfully. Growth may
require increased recruiting efforts, business development, and selling, marketing and other actions that are expensive and
increase risk. We may need to invest more in our people and systems, controls, compliance efforts, policies and procedures
than we anticipate. Further, we may need to enhance or modify our systems or processes, or transition to more efficient or
effective ones, and these changes and how we handle them may impact the business in short- or long-term. Therefore, even
if we do grow, the demands on our people and systems, controls, compliance efforts, policies and procedures may adversely
affect the quality of our work, our operating margins, and our operating results, at least in the short-term, and perhaps in the
long-term.

Efforts involving a different focus, new services, new clients, new practice areas, and new lines of business, include
risks associated with our inexperience and competition from mature participants in those areas. Our expansion of services
may result in decisions that could harm our profit and operating results. In particular, implementation and improvement
services often relate to the development, implementation and improvement of critical infrastructure or operating systems that
our clients may view as “mission critical,” and if we fail to satisfy the needs of our clients in providing these services, our
clients could incur significant costs and losses for which they could seek compensation from us.

The diversity of the services we provide, and the clients we serve, may create actual, potential, and perceived conflicts
of interest and business conflicts that limit our growth and could lead to potential liabilities for us.

Because we provide services to a wide array of both government and commercial clients, occasions arise where, due
to actual, potential, or perceived conflicts of interest or business conflicts, we cannot perform work for which we are qualified.
A number of our contracts contain limitations on the work we can perform for others, such as, for example, when we are
assisting a government agency or department in developing regulations or enforcement strategies. Actual, potential, and
perceived conflicts limit the work we can do and, consequently, can limit our growth and adversely affect our operating
results. In addition, if we fail to address actual or potential conflicts properly, or even if we simply fail to recognize a perceived
conflict, we may be in violation of our existing contracts, may otherwise incur liability, may lose future business for not
preventing the conflict from arising, and our reputation may suffer. Particularly as we continue to grow our commercial
business, we anticipate that conflicts of interest and business conflicts will pose a greater risk.

Our relationships with other contractors are important to our business and, if disrupted, could cause us damage.

We derive a portion of our revenue from contracts under which we act as a subcontractor or from “teaming”
arrangements in which we and other contractors jointly bid on particular contracts, projects, or programs. As a subcontractor
or team member, we often lack control over fulfillment of a contract, and poor performance on the contract, whether resulting
from our performance or the performance of another contractor, could tarnish our reputation, result in a reduction of the
amount of our work under, or termination of, that contract or other contracts, and cause us not to obtain future work, even
when we perform as required. Moreover, our revenue, profit and operating results could be adversely affected if any prime
contractor or teammate does not pay our invoices in a timely fashion, chooses to offer products or services of the type that
we provide, teams with other companies to provide such products or services, or otherwise reduces its reliance upon us for
such products or services.

We depend on our intellectual property and our failure to protect it could harm our competitive position.

Our success depends in part upon our internally-developed technology and models, proprietary processes, and other
intellectual property that we incorporate in our products and utilize to provide our services. If we fail to protect our intellectual
property, our competitors could market services or products similar to our services and products, which could reduce demand
for our offerings. Government clients typically retain a perpetual, worldwide, royalty-free right to use the intellectual property
we develop for them in a manner defined within government regulations, including providing it to other government agencies
or departments, as well as to our competitors in connection with their performance of government contracts. When necessary,
we seek authorization to use intellectual property developed for the government or to secure export authorization. Government
clients may grant us the right to commercialize software developed with government funding, but they are not required to do

so. If we improperly use intellectual property that was even partially funded by government clients, these clients could seek
damages and royalties from us, sanction us, and prevent us from working on future government contracts. Actions could also
be taken against us if we improperly use intellectual property belonging to others besides our government clients. In addition,
there can be substantial costs associated with protecting our intellectual property, which can also have an adverse effect on
our results of operations.

We may be harmed by intellectual property infringement claims.

We have been subject to claims, and are likely to be subject to future claims, that the intellectual property we use in
delivering services and business solutions to our clients infringes upon the intellectual property rights of others. Our
employees develop much of the intellectual property that we use to provide our services and business solutions to our clients,
but we also acquire or obtain rights to use intellectual property through mergers or acquisitions of other companies, engage
third parties to assist us in the development of intellectual property and license technology from other vendors. If our vendors,
our employees or third parties assert claims that we or our clients are infringing on their intellectual property, we could incur
substantial costs to defend those claims, even if we prevail. In addition, if any of these infringement claims are ultimately
successful, we could be required to:

•

Pay substantial damages;

Cease selling and using products and services that incorporate the challenged intellectual property;

Obtain a license or additional licenses from our vendors or other third parties, which may not be available on
commercially reasonable terms or at all; and

Re-design our products and services that rely on the challenged intellectual property, which may be very
expensive or commercially impractical.

Any of these outcomes could further adversely affect our operating results.

Systems and/or service failures could interrupt our operations, leading to reduced revenue and profit.

Any interruption in our operations or any systems failures, including, but not limited to: (i) the inability of our staff
to perform their work in a timely fashion, whether caused by limited access to and/or closure of our and/or our clients’ offices
or otherwise; (ii) the failure of network, software and/or hardware systems; and (iii) other interruptions and failures, whether
caused by us, a third-party service provider, unauthorized intruders and/or hackers, computer viruses, natural disasters, power
shortages, terrorist attacks or otherwise, could cause loss of data and interruptions or delays in our business or that of our
clients, or both. In addition, the failure or disruption of mail, communications and/or utilities could cause an interruption or
suspension of our operations or otherwise harm our reputation or business. Our property and business interruption insurance
may be inadequate to compensate us for all losses that may occur as a result of any system or operational failure or disruption
and, as a result, revenue, profits and operating results could be adversely affected.

Improper disclosure of confidential and personal data and breaches of, or disruptions to, our information technology
systems or those of our third- party providers, could adversely affect our business and could result in liability and
harm our reputation.

We store and process increasingly large amounts of confidential information concerning our employees, customers
and vendors, as well as confidential information on behalf of our customers (such as information regarding applicants in
programs on which we perform services through our contractual relationships with customers). Therefore, we must ensure
that we are at all times compliant with the various privacy laws, rules, and regulations in all of the countries within which we
are operating. These laws, rules, and regulations can vary significantly from country to country, with many being more
onerous than those in the U.S. For example, the European Union adopted a new regulation that became effective in May
2018, called the General Data Protection Regulation (“GDPR”), which requires companies to meet stringent requirements
regarding the handling of personal data, including its use, protection and transfer and the ability of persons whose data is
stored to correct or delete such data about themselves. Failure to meet the GDPR requirements could result in significant
penalties, including fines up to 4% of annual worldwide revenue. The GDPR also confers a private right of action on certain
individuals and associations. Moreover, we must ensure that all of our vendors who have access to such information also
have the appropriate privacy policies, procedures and protections in place. There can be substantial costs associated with
protecting confidential information and maintaining compliance with the various privacy laws, rules and regulations, which
could have an adverse effect on our results of operations. In addition, any inability, real or perceived, to adequately address
privacy and data protection concerns, even if unfounded, or comply with applicable laws, regulations, policies, industry
standards, contractual obligations, or other legal obligations (including at newly acquired companies), could result in
additional cost and liability to us, damage our reputation, inhibit our ability to win new contracts, and otherwise adversely
affect our business.

The continued occurrence of high-profile data breaches of other companies provides evidence of an external
environment increasingly hostile to information security. In particular, cybersecurity attacks are evolving, and we face the
constant risk of cybersecurity threats, whether from deliberate attacks or unintentional events, including computer viruses,
attacks by computer hackers, malicious code, cyber and phishing attacks, and other electronic security breaches, including
unauthorized access to our and our clients’ systems, that could lead to disruptions in critical systems, unauthorized release of
confidential or otherwise protected information and/or corruption of data. In particular, as a federal government contractor,
we face a heightened risk of a security breach or disruption with respect to personally identifiable, sensitive but unclassified,
classified, or otherwise protected data resulting from an attack by computer hackers, foreign governments and/or cyber
terrorists. Improper disclosure of this information could harm our reputation and affect our relationships with business
partners, lead to legal exposure, or subject us to liability under laws, rules and regulations that protect personal or other
confidential data, resulting in increased costs or loss of revenue. Although we devote significant resources to our cybersecurity
programs and have implemented security measures to protect our systems and to prevent, detect and respond to cybersecurity
incidents, there can be no assurance that our efforts will prevent these threats. As these security threats continue to evolve,
we may be required to devote additional resources to protect, prevent, detect and respond against cybersecurity attacks, system
disruptions and security breaches. Moreover, we also rely in part on third-party software and information technology vendors
to run our information systems. Any failure of these third-party systems, which are outside of our control but still impact us,
could have similar adverse effects.

RISKS RELATED TO ACQUISITIONS

When we undertake acquisitions, they may present integration challenges, fail to perform as expected, increase our
liabilities, and/or reduce our earnings.

One of our growth strategies is to make strategic acquisitions. When we complete acquisitions, it may be challenging
and costly to integrate the acquired businesses due to operating and integrating new accounting systems, differences in the
locations of personnel and facilities, differences in corporate cultures, disparate business models, or other reasons. If we are
unable to successfully integrate acquired companies, our revenue and operating results could suffer. In addition, we may not
successfully achieve the anticipated cost efficiencies and synergies from these acquisitions. Also, our costs for managerial,
operational, financial, and administrative systems may increase and be higher than anticipated. During and following the
integration of an acquired business, we may experience attrition, including losing key employees and/or clients of the acquired
business, which could adversely affect our future revenue and operating results and prevent us from achieving the anticipated
benefits of the acquisition.

Businesses we acquire may have liabilities or adverse operating issues, or both, that we either fail to discover through
due diligence or underestimate prior to the consummation of the acquisition. These liabilities and/or issues may include the
acquired business’ failure to comply with, or other violations of, applicable laws, rules, or regulations or contractual or other
obligations or liabilities. As the successor owner, we may be financially responsible for, and may suffer harm to our reputation
or otherwise be adversely affected by, such liabilities and/or issues. An acquired business also may have problems with
internal controls over financial reporting, which could in turn cause us to have significant deficiencies or material weaknesses
in our own internal controls over financial reporting. These and any other costs, liabilities, issues, and/or disruptions
associated with any past or future acquisitions, and the related integration, could harm our operating results.

As a result of our acquisitions, we have substantial amounts of goodwill and intangible assets, and changes in business
conditions could cause these assets to become impaired, requiring write-downs that would adversely affect our
operating results.

All of our acquisitions have involved purchase prices well in excess of tangible asset values net of liabilities assumed,
resulting in the creation of a significant amount of goodwill and other intangible assets. As of December 31, 2018, goodwill
and purchased intangibles accounted for approximately 59% and 3%, respectively, of our total assets. Under U.S. generally
accepted accounting principles (“U.S. GAAP”), we do not amortize goodwill and intangible assets acquired in a purchase
business combination that are determined to have indefinite useful lives. Instead, we review them for impairment annually
(or more frequently if impairment indicators arise). Although we have to date determined that such assets have not been
impaired, future events or changes in circumstances that result in an impairment of goodwill or other intangible assets would
have a negative impact on our profitability and operating results.

RISKS RELATED TO OUR CORPORATE AND CAPITAL STRUCTURE

Provisions of our charter documents and Delaware law may prevent or deter potential acquisition bids to acquire us
and other actions that stockholders may consider favorable, and the market price of our common stock may be lower
as a result.

•

Our charter documents contain the following provisions that could have an anti-takeover effect:

Our board of directors is divided into three classes, making it more difficult for stockholders to change the
composition of the board;

Directors may be removed only for cause;

Our stockholders are not permitted to call a special meeting of the stockholders;

All stockholder actions are required to be taken by a vote of the stockholders at an annual or special meeting or
by a written consent signed by all of our stockholders;

Our stockholders are required to comply with advance notice procedures to nominate candidates for election to
our board of directors or to place stockholders’ proposals on the agenda for consideration at stockholder
meetings; and

The approval of the holders of capital stock representing at least two-thirds of our voting power is required to
amend our indemnification obligations, director classifications, stockholder proposal requirements, and director
candidate nomination requirements set forth in our amended and restated certificate of incorporation and
amended and restated bylaws.

In addition, we are subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law,
which regulates corporate acquisitions. These provisions could discourage potential acquisition proposals; delay or prevent a
change-in-control transaction; discourage others from making tender offers for our common stock; and/or prevent changes in
our management.

There are risks associated with our outstanding and future indebtedness which could reduce our profitability, limit
our ability to pursue certain business opportunities and reduce the value of our stock.

As of December 31, 2018, we had an aggregate of $200.4 million of outstanding indebtedness under a credit facility
that will mature on May 17, 2022. Subject to the limits contained in the agreements governing our outstanding debt, we may
incur additional debt in the future. Our ability to pay interest and repay the principal for our indebtedness, as well as meet our
financial and operating covenant requirements, is dependent upon our ability to, among other things, manage our business
operations, and generate sufficient cash flows to service such debt. If we are unable to comply with the terms of our financing
agreements or obtain additional required financing, this could ultimately result in a significant adverse effect on our financial
results and the value of our stock. Among other things, our debt could:

•

Make it difficult to obtain additional financing for working capital, capital expenditures, acquisitions, or other
general corporate purposes;

Result in a substantial portion of our cash flows from operations being dedicated to the payment of the principal
and interest on our debt, as well as used to make debt service payments;

Limit our flexibility in planning for, and reacting to, changes in our business and the marketplace;

Place us at a competitive disadvantage relative to other less leveraged firms; and

Increase our vulnerability to economic downturns and rises in interest rates.

Should any of these or other unforeseen consequences arise, they could have an adverse effect on our business,
financial condition, results of operations, future business opportunities and/or ability to satisfy our obligations under our debt.

We cannot assure you that we will pay special or regular dividends on our stock in the future.

The board of directors authorized, declared and paid regular dividends in each quarter of 2018 for the first time in the
Company’s history. The declaration of any future dividends and the establishment of the per share amount, record dates and
payment dates for any such future dividends are subject to the discretion of the board of directors taking into account future
earnings, cash flows, net income, dividend yield and other factors. Authorization of dividends by the Board is subject to
adherence/compliance with the Company’s credit facility. There can be no assurance that the board of directors will declare
any dividends in the future. To the extent that expectations by market participants regarding the potential payment, or amount,
of any special or regular dividend prove to be incorrect, the price of our common stock may be materially and negatively
affected and investors that bought shares of our common stock based on those expectations may suffer a loss on their
investment.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 2.

PROPERTIES

We lease our offices and do not own any real estate. As of December 31, 2018, we leased approximately 313,658
square feet of office space at our corporate headquarters at 9300/9302 Lee Highway, Fairfax, Virginia (in the Washington,
D.C. metropolitan area) through December 2022 (the “Fairfax Offices”). The Fairfax Offices house a portion of our operations
and almost all of our corporate functions, including most of our staff within executive management, treasury, accounting,
legal, human resources, business and corporate development, facilities management, information services, and contracts.

As of December 31, 2018, we had leases in place for approximately 1.2 million square feet of office space in more
than 80 office locations throughout the U.S. and around the world, with various lease terms expiring over the next nine years.
As of December 31, 2018, approximately 13,325 square feet of the space we leased was subleased to other parties. We believe
that our current office space, as well as other office space we expect to be able to lease, will meet our needs for the next
several years. Lastly, a portion of our operations staff is housed at client-provided facilities, pursuant to the terms of a number
of our client contracts.

ITEM 3. LEGAL PROCEEDINGS

We are involved in various legal matters and proceedings arising in the ordinary course of business. While these
matters and proceedings cause us to incur costs, including, but not limited to, attorneys’ fees, we currently believe that any
ultimate liability arising out of these matters and proceedings will not have a material adverse effect on our financial position,
results of operations, or cash flows.

An update on litigation related to our Road Home contract is discussed in “Note 19— Commitments and

Contingencies — Road Home Contract” in our financial statements.

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND

ISSUER PURCHASES OF EQUITY SECURITIES

Market Information

Our common stock trades on the NASDAQ Global Select Market under the symbol “ICFI.”

Holders

As of February 22, 2019, there were 32 registered holders of record of our common stock. This number is not
representative of the number of beneficial holders because many of the shares are held by depositories, brokers, or nominees.

Dividends

We currently expect to continue paying dividends comparable with our historic dividend payments. The declaration
and payment of any dividends is at the sole discretion of the board of directors and is not guaranteed. Our amended credit
facility contains certain restrictions related to the payment of cash dividends, requiring us to meet certain covenants prior to
and after the declaration of any dividend.

Stock Performance Graph

The following graph compares the cumulative total stockholder return on our common stock from December 31,
2013 through December 31, 2018, with the cumulative total return on (i) the NASDAQ Composite, (ii) the Russell 2000 stock
index, and (iii) the Company’s 2018 peer group composed of other governmental and commercial service providers: Booz
Allen Hamilton Holding Corporation; CACI International Inc.; CBIZ, Inc.; CRA International, Inc.; Engility Holdings, Inc.;
Exponent Inc.; FTI Consulting, Inc.; GP Strategies Corporation; Huron Consulting Group Inc.; ManTech International
Corporation; Maximus, Inc.; Navigant Consulting, Inc.; Resources Connection, Inc.; Science Applications International
Corporation; Tetra Tech, Inc.; Unisys Corporation; and VSE Corporation (the “2018 Peer Group”). As part of the annual
process of reviewing the peer group, management ensures that the selected companies remain aligned with the Company’s
evolving business strategy. With respect to our 2018 Peer Group, there was one company that was on the 2017 peer group
that has been removed due to mergers and acquisition activities during the year, Convergys Corporation. Engility Holdings,
Inc. was added to the 2018 Peer Group. The comparison below assumes an initial investment of $100.00 on December 31,
2013 in which all dividends (if any) are reinvested and all returns are market-cap weighted. The historical information set

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

OF OPERATIONS

The following discussion and analysis should be read in conjunction with the “Selected Financial Data” and the
consolidated financial statements and related notes included elsewhere in this Annual Report on Form 10-K. This discussion
and analysis contains forward-looking statements that involve risks, uncertainties, and assumptions, such as statements of
our plans, objectives, expectations, and intentions. The cautionary statements made in this Annual Report on Form 10-K
should be read as applying to all related forward-looking statements wherever they appear in this Annual Report on Form
10-K. Our actual results could differ materially from those anticipated in the forward-looking statements. Factors that could
cause or contribute to our actual results differing materially from those anticipated include those discussed in “Risk Factors”
and elsewhere in this Annual Report on Form 10-K.

OVERVIEW AND OUTLOOK

We provide professional services and technology-based solutions to government and commercial clients. Our services
include management, marketing, technology, and policy consulting and implementation services. We help our clients
conceive, develop, implement, and improve solutions that address complex natural resource, social, and public safety issues.
Our clients operate in four key markets: energy, environment, and infrastructure; health, education, and social programs;
safety and security; and consumer and financial. Drawing from our domain knowledge and staff experience in working in
multi-disciplinary teams for clients in a variety of markets, we provide services that deliver value throughout the entire life
cycle of a policy, program, project, or initiative, from initial research, analysis, assessment and advice to design and
implementation of programs and technology-based solutions, and the provision of engagement services and programs.

Our clients utilize our services because we combine diverse institutional knowledge and experience with the deep
subject matter expertise of our highly educated staff, which we deploy in multi-disciplinary teams. We have successfully
worked with many of our clients for decades, with the result that we have a thorough and nuanced perspective of their
objectives and needs. We serve both governmental and commercial clients. Our government clients include those from
departments and agencies of the federal government, state (including territories) and local governments, and international
governments. Our government efforts include work performed under subcontract agreements to commercial clients whose
ultimate customer is government agencies and departments.

Our largest clients are U.S. federal government departments and agencies. In fact, our federal government clients
have included every cabinet-level department, most significantly HHS, DOS, and DoD. Federal government clients generated
approximately 41%, 45%, and 48% of our revenue in 2018, 2017, and 2016, respectively. State and local government clients
generated approximately 14%, 10%, and 11% of our revenue in 2018, 2017, and 2016, respectively. International government
clients generated approximately 9%, 7%, and 6% of our revenue in 2018, 2017, and 2016, respectively.

We also serve a variety of commercial clients worldwide, including: airlines, airports, electric and gas utilities, oil
companies, hospitals, health insurers and other health-related companies, banks and other financial services companies,
transportation, travel and hospitality firms, non-profits/associations, law firms, manufacturing firms, retail chains, and
distribution companies. Our commercial clients, which include clients outside the U.S., generated approximately 36%, 38%,
and 35% of our revenue in 2018, 2017, and 2016, respectively.

We report operating results and financial data as a single segment based on the consolidated information used by our
chief operating decision-maker in evaluating the financial performance of our business and allocating resources. Our single
segment represents our core business—professional services for government and commercial clients. Although we describe
our multiple service offerings to clients that operate in four markets to provide a better understanding of the scope and scale
of our business, we do not manage our business or allocate our resources based on those service offerings or client markets.
Rather, on a project by project basis, we assemble the best team from throughout the enterprise to deliver highly customized
solutions that are tailored to meet the needs of each client.

In 2018, our total revenue increased to $1,338.0 million, an increase of $108.8 million, or 8.9%, for the year ended
December 31, 2018 compared to $1,229.2 million in the prior year. Operating income increased $9.9 million, or 12.0%, to
$92.3 million for the year ended December 31, 2018 compared to the prior year due to the increase in gross profit which
outpaced increases in indirect and selling expenses, and decreases in depreciation and amortization expense, and amortization
of intangible assets. Indirect and selling expenses increased by $14.5 million compared to the prior year primarily due to
increases in indirect labor and indirect operating expenses, offset by a reduction in incentive compensation. Net income
decreased $1.5 million, or 2.3%, to $61.4 million, largely driven by an increase of income tax expense of $10.3 million
compared to the prior year due to a $16.8 million decrease in income tax expense in 2017, which related to a one-time
favorable adjustments of $16.2 million recorded in 2017 as a result of the enactment of the Tax Act in December 2017.

We believe that demand for our services will continue to grow as government, industry, and other stakeholders seek
to address critical long-term societal and natural resource issues due to heightened concerns about clean energy and energy
efficiency; health promotion, treatment, and cost control; and ongoing homeland security threats. We also see significant
opportunity to further leverage our digital and client engagement capabilities across our commercial and government client
base. Our future results will depend on the success of our strategy to enhance our client relationships and seek larger
engagements that span the entire program life cycle, and to complete and successfully integrate additional strategic
acquisitions. We will continue to focus on broadening domain expertise and building scale in key client markets and
geographies by developing business with existing and new government and commercial clients and replicating our business
model in selective geographies. In doing so, we will continue to evaluate strategic acquisition opportunities, seeking
acquisitions that promote the achievement of strategic objectives like enhancing our subject matter knowledge, broadening
our service offerings, and/or providing scale in specific geographies, and from which we believe that we can earn an
acceptable return.

U.S. federal government revenue was 41% of our total revenue for the year ended December 31, 2018. While we
continue to see favorable long-term market opportunities, there are certain near-term challenges facing all government service
providers, including top-line legislative constraints on federal government discretionary spending and actions by Congress
or the Administration that could result in a delay or reduction to our current revenue, profit and cash flows, and have a
negative impact on our on-going business and results of operations. However, we believe we are well positioned in budget
areas that will continue to be priorities to the federal government.

We believe that the combination of internally-generated funds, available bank borrowings, and cash and cash
equivalents on hand will provide the required liquidity and capital resources necessary to fund on-going operations, potential
acquisitions, customary capital expenditures, and other working capital requirements.

Our results of operations and cash flows may vary significantly from quarter to quarter depending on a number of

factors, including, but not limited to:

•

Progress of contract performance;

Extraordinary economic events and natural disasters;

Number of billable days in a quarter;

Timing of client orders;

Timing of award fee notices;

Changes in the scope of contracts;

Variations in purchasing patterns under our contracts;

Federal and state (including territories) and local governments’ and other clients’ spending levels;

Federal government shutdowns;

Timing of billings to, and payments by clients;

Timing of receipt of invoices from, and payments to, employees and vendors;

Commencement, completion, and termination of contracts;

Strategic decisions, such as acquisitions, consolidations, divestments, spin-offs, joint ventures, strategic
investments, and changes in business strategy;

Timing of significant costs and investments (such as bid and proposal costs and the costs involved in planning
or making acquisitions);

Timing of events related to discrete tax items;

Our contract mix and use of subcontractors or the timing of other direct costs for which we may earn lower
contract margin;

•

Changes in contract margin performance due to performance risks;

Additions to, and departures of, staff;

Changes in staff utilization;

Paid time off taken by our employees;

Level and cost of our debt;

Changes in accounting principles and policies; and/or

General market and economic conditions.

Because a significant portion of our expenses (such as personnel, facilities, and related costs) are fixed in the short
term, contract performance and variation in the volume of activity, as well as in the number and volume of contracts
commenced or completed during any year, may cause significant variations in operating results from year to year. We
generally have been able to price our contracts in a manner that accommodates the rates of inflation experienced in recent
years, although we cannot ensure that we will be able to do so in the future.

ACQUISITIONS AND BUSINESS COMBINATIONS

A key element of our growth strategy is to pursue acquisitions. In 2016, we acquired Trade NTE and in 2018, we
acquired The Future Customer (“TFC”), DMS Disaster Consultants (“DMS”), and We Are Vista Limited (“Vista”). While
providing capabilities and access to new clients in support of our growth strategy, these acquisitions were not significant to
our financial statements taken as a whole.

Trade NTE. - In November 2016, we acquired certain contracts of Trade NTE, a Georgia-based company specializing
in strategic marketing and branding services. The acquisition enhanced our branding services through existing engagements
and relationships with its clients and customers.

The Future Customer. - In January 2018, we acquired TFC, a leading boutique loyalty strategy and marketing
company based in London. TFC has provided additional capabilities and access to clients in support of our 1to1 loyalty and
customer relationship marketing efforts.

DMS Disaster Consultants – In August 2018, we acquired DMS, a disaster management and recovery firm, to broaden
our capabilities in support of assisting communities, businesses and individuals recover from man-made and nature disasters.
DMS assists public sector clients with man-made and natural disaster planning and preparedness, and post-disaster response
and recovery efforts by assisting clients in obtaining federal funding from Federal Management Agency (FEMA), insurance
companies, and other sources.

We Are Vista Limited – In October 2018, we acquired Vista, a communications company headquartered in Leeds,
U.K., with an additional presence in London. Vista provides advisory services and solutions to clients in the financial, retail,
automobile, and energy industries and broadens our capabilities in the region.

CRITICAL ACCOUNTING POLICIES

Our discussion of our financial condition and results of operations is based on our consolidated financial statements
prepared in accordance with U.S. GAAP. The preparation of these consolidated financial statements requires us to make
certain estimates and judgments that affect the reported amounts of assets, liabilities, revenue, and expenses and our
application of critical accounting policies, including: revenue recognition, impairment of goodwill and other intangible assets,
income taxes, and stock-based compensation. If any of these estimates or judgments prove to be incorrect, our reported results
could be materially affected. Actual results may differ significantly from our estimates under different assumptions or
conditions. We believe that the estimates, assumptions and judgments involved in the accounting practices described below
have the greatest potential impact on our financial statements and, therefore, consider them to be critical accounting policies.
Significant accounting policies, including the critical accounting policies listed below, are more fully described and discussed
in “Note 2—Summary of Significant Accounting Policies” in the “Notes to Consolidated Financial Statements.”

Revenue Recognition

We periodically evaluate our critical accounting policies and estimates based on changes in U.S. GAAP that may
have an effect on our consolidated financial statements. In May 2014, the Financial Accounting Standards Board (“FASB”)
issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606). Topic 606
provides a single comprehensive revenue recognition framework and supersedes existing revenue recognition guidance.
Included in the new principles-based revenue recognition model are changes to the basis for determining the timing for
revenue recognition. In addition, the standard expands and improves revenue disclosures.

We implemented Topic 606 on January 1, 2018 using the modified retrospective method. This method requires that
we apply the requirements of the new standard in the year of adoption to new contracts and those that were not completed as
of the adoption date, but not retroactively restate prior years. Management evaluated those contracts not completed as of
January 1, 2018 (the adoption date) and concluded that the impact of adopting ASC 606 did not have a material impact on
our consolidated financial statements taken as a whole. Contract assets and contract liabilities were formerly reported as
unbilled accounts receivable and deferred revenue, respectively. For further discussion see “Note 2 – Summary of Significant
Accounting Policies – Revenue Recognition” and “Note 2 – Summary of Significant Accounting Policies – Recent
Accounting Pronouncements – Revenue Recognition” in the “Notes to Consolidated Financial Statements” in this Annual
Report.

Under the modified retrospective method, we were required to maintain dual reporting during the year of adoption in
order to present revenue under both the previous and new accounting for contracts initiated on or after the date of adoption
and for those contracts having remaining obligations as of the adoption date. Revenue timing differences between the two
methods resulted primarily from contracts with performance incentives. Under the new accounting, we have included in
revenue the most likely amount of priced incentives earned as contract work was performed rather than, as under the old
accounting, waiting to recognize revenue from incentives until specific quantitative goals were achieved, generally at the end
of each contractually-stipulated performance assessment period. While there were differences in the amount of revenue
recognized during each quarter of the year, the timing differences did not result in a material change to our annual revenue
since most incentives have performance assessment periods which are aligned with our fiscal year.

We primarily provide services and technology-based solutions for clients that operate in a variety of markets and the
solutions may span the entire program life cycle, from initial research and analysis to the design and implementation of
solutions. We enter into agreements with clients that create enforceable rights and obligations and for which it is probable
that we will collect the consideration to which it will be entitled as services and solutions are transferred to the client. Except
in certain narrowly defined situations, our agreements with its clients are written and revenue is generally not recognized on
oral or implied arrangements. We recognize revenue based on the consideration specified in the applicable agreement and
exclude from revenue amounts collected on behalf of third parties. Accordingly, sales and similar taxes which are collected
for third parties are excluded from the transaction price.

We also evaluate whether two or more agreements should be accounted for as one single contract and whether
combined or single agreements should be accounted for as more than one performance obligation. For most contracts, the
client requires that we perform a number of tasks in providing an integrated output and, hence, each of these contracts are
tracked as having only one performance obligation. When contracts are separated into multiple performance obligations, we
allocate the total transaction price to each performance obligation based on the estimated relative standalone selling prices of
the promised services underlying each performance obligation. We generally provide customized solutions in which the
pricing is based on specific negotiations with each client, and, in these cases, we use a cost-plus margin approach to estimate
the standalone selling price of each performance obligation. It is common for our long-term contracts to contain award fees,
incentive fees or other provisions that can either increase or decrease the transaction price. These variable amounts are
generally awarded at the completion of a prescribed performance assessment period based on the achievement of performance
metrics, program milestones or cost targets, and the amount awarded may be subject to client discretion. We estimate variable
consideration as the most likely amount to which we expect to be entitled.

We evaluate contractual arrangements to determine whether revenue should be recognized on a gross versus net basis.
Our assessment is based on the nature of the promise to the client. In most cases, we agree to provide specified services to
the client as a principal and revenue is recognized on a gross basis. In rare cases, we act as an agent and merely arrange for
another party to provide services to the client and revenue is recognized on a net basis in reflection of the fact that we do not
control the goods or services provided to the client by the other party.

Long-term contracts typically contain billing terms that provide for invoicing once a month and payment on a net 30-
day basis. Exceptions to monthly billing terms are to ensure that we perform satisfactorily rather than representing a
significant financing component. For cost-based contracts, our performance is evaluated during a contractually stipulated
performance period and, while contract costs may be billed on a monthly basis, we are generally permitted to bill for incentive
or award fees only after the completion of the performance assessment period, which may occur quarterly, semi-annually or
annually, and after the client completes the performance assessment. Fixed-price contracts may provide for milestone billings
based on the attainment of specific project objectives and, since they are tied to our project performance, these type of billing
terms do not represent a significant financing component. Moreover, contracts may require retentions or hold backs that are
paid at the end of the contract to ensure that we perform in accordance with requirements which do not represent our providing
financing to our clients but rather are a means to ensure that we meet contract requirements. We do not assess whether a
contract contains a significant financing component if we expect, at contract inception, that the period between payment by
the client and the transfer of promised services to the client will be one year or less.

As a service provider, we generally recognize revenue over time as control is transferred to a client, based on the
extent of progress towards satisfaction of the performance obligation. The selection of the method used to measure progress
requires judgment and, among other things, is dependent on the contract type selected by the client during contract negotiation
and the nature of the services and solutions to be provided.

When a performance obligation is billed using a time-and-materials contract type, we use output progress measures
to estimate revenue earned based on hours worked in contract performance at negotiated billing rates. Fixed-price level-of-
effort contracts are substantially similar to time-and-materials contracts except that we are required to deliver a specified
level of effort over a stated period of time. For these contracts, we estimate revenue earned using contract hours worked at
negotiated bill rates as we deliver the contractually required workforce.

For cost-based contracts, we recognize revenue as a single performance obligation based on contract costs incurred,
as we become contractually entitled to reimbursement of the contract costs, plus a most likely estimate of award or incentive
fees earned on those costs even though final determination of fees earned occurs after the contractually-stipulated
performance assessment period ends.

For performance obligations requiring the delivery of a service for a fixed price, we use the ratio of actual costs
incurred to total estimated costs, provided that costs incurred (an input method) represents a reasonable measure of progress
towards the satisfaction of a performance obligation, in order to estimate the portion of total revenue earned. This method
provides a faithful depiction of the transfer of value to the client when we are satisfying a performance obligation that entails
integration of tasks for a combined output which requires us to coordinate the work of employees, subcontractors and delivery
of other contract costs. Contract costs that are not reflective of our progress to satisfying a performance obligation are not
included in the calculation of the measure of progress. When this method is used, changes in estimated costs to complete
these obligations result in adjustments to revenue on a cumulative catch-up basis, which causes the effect of revised estimates
for prior periods to be recognized in the current period. Changes in these estimates can routinely occur over contract
performance for a variety of reasons, which include: changes in contract scope; changes in contract cost estimates due to
unanticipated cost growth or reassessments of risks impacting costs; changes in estimated incentive or award fees; or
performing better or worse than previously estimated.

In some fixed price service contracts we performs services of a recurring nature, such as maintenance and other
services of a “stand ready” nature. For these contracts, we have the right to consideration in an amount that corresponds
directly with the value that the client has received. Therefore, the Company records revenue on a time-elapsed basis to reflect
the transfer of control to the client throughout the contract.

Our operating cycle for long-term contracts may be greater than one year and is measured by the average time
intervening between the inception and the completion of those contracts. Contract-related assets and liabilities, as highlighted
below, are classified as current assets and current liabilities. Significant balance sheet accounts related to the revenue
recognition cycle are as follows:

Contract receivables, net – This account includes amounts billed or billable under contract terms. The amounts due
are stated at their net realizable value. We maintain an allowance for doubtful accounts to provide for the estimated
amount of receivables that will not be collected. We consider a number of factors in its estimate of the allowance,
including knowledge of a client’s financial condition, its historical collection experience, and other factors relevant
to assessing the collectability of the receivables.

Contract assets – This account includes unbilled amounts typically resulting from revenue recognized on long-
term contracts when the amount of revenue recognized exceeds the amounts billed. It also includes contract
retainages until we have met the contract-stipulated requirements for payment. Contract assets are reported in a
net position on a contract by contract basis each period even though individual contracts may contain multiple
performance obligations. On a contract by contract basis, amounts do not exceed their net realizable value.

Contract liabilities – This account consists of advance payments received and billings in excess of revenue
recognized on long-term contracts. Contact liabilities are reported in a net position on a contract by contract basis
each period even though individual contracts may contain multiple performance obligations.

Revenue recognition entails the use of significant judgment, including, but not limited to, the following: evaluating
agreements in terms of the number and nature of performance obligations; determining the appropriate method for measuring
progress to satisfaction of obligations; and preparing estimates in terms of the amount of progress that we have made. Most
of our revenue is recognized over time and for many fixed-price contracts, in particular, we estimate the proportion of total
revenue earned using the ratio of contract costs incurred to total estimated contract costs, which requires us to prepare
estimates as work progresses of contract cost left to be incurred. Moreover, some of our contracts include variable
consideration, which requires us to estimate the most likely amounts that will be earned over the respective contractually-
stipulated performance assessment periods. For these obligations, changes in estimates result in cumulative catch-up
adjustments and may have a significant impact on earnings during a given period.

Contractual arrangements are evaluated to assess whether revenue should be recognized on a gross versus net basis.
Management’s assessment when determining gross versus net revenue recognition is based the nature of the promise to the
client. In most cases, we agree to provide specified services to the client as a principal and revenue is recognized on a gross
basis. In rare cases, we act as an agent and merely arrange for another party to provide services to the client and revenue is
recognized on a net basis in reflection of the fact that we do not control the goods or services provided to the client by the
other party.

Payments on cost-based contracts with the U.S. federal government are provisional payments subject to audit and
adjustment. Indirect costs applied to government contracts are also subject to audit and adjustment and such audits have been
finalized only through December 31, 2010. Contract revenue has been recorded in amounts that are expected to be realized
on final audit and settlement of costs.

We prepare client invoices in accordance with the terms of the applicable contract, and billing terms may not be
directly related to the performance of services. Unbilled receivables are invoiced based on the achievement of specific events
as defined by each contract, including deliverables, timetables, and incurrence of certain costs. Unbilled receivables are
classified as a current asset. Advanced billings to clients in excess of revenue earned are recorded as contract liabilities until
the revenue recognition criteria are met. Reimbursements of out-of-pocket expenses are included in revenue with
corresponding costs incurred by us included in the cost of revenue. We record revenue net of taxes collected from clients
when the taxes are collected on behalf of the governmental authorities.

We may proceed with work based on client direction prior to the completion and signing of formal contract
documents. We have a review process for approving any such work. Revenue associated with such work is recognized only
when it can be reliably estimated and realization is probable. We base our estimates on a variety of factors, including previous
experiences with the client, communications with the client regarding funding status, and its knowledge of available funding
for the contract.

Goodwill and Other Intangible Assets

The purchase price of an acquired business is allocated to the tangible assets and separately identifiable intangible
assets acquired, less liabilities assumed, based on their respective fair values, with the excess recorded as goodwill. Goodwill
represents the excess of costs over the fair value of net assets of businesses acquired. Goodwill and intangible assets acquired
in a purchase business combination and determined to have an indefinite useful life are not amortized, but instead reviewed
annually for impairment, or more frequently if impairment indicators arise. Intangible assets with estimable useful lives are
amortized over such lives and reviewed for impairment if impairment indicators arise. As of December 31, 2018, goodwill
and intangibles assets were $715.6 million and $35.5 million, respectively.

For the purpose of performing the annual goodwill impairment review as of October 1, 2018, we have one aggregated
reporting unit at a consolidated entity level. We assess goodwill at the reporting level. As our business is highly integrated
and all of our components have similar economic characteristics, we concluded we have one reporting unit at the consolidated
entity level. For the goodwill impairment test, we opted to perform a qualitative assessment of whether it is more likely than
not that the reporting unit's fair value is less than its carrying amount. If, after completing the qualitative assessment, we
determine that it is more likely than not that the estimated fair value of the reporting unit exceeded the carrying amount, we
may conclude that no impairment exists. If we conclude otherwise, a goodwill impairment test must be performed, which
includes a comparison of the fair value of the reporting unit to its carrying amount and recognizing as an impairment loss the
difference of the estimated fair value of the reporting unit over its carrying amount.

Our qualitative analysis as of October 1, 2018 included macroeconomic and industry and market-specific
considerations, financial performance indicators and measurements, and other factors. Based on this qualitative assessment,
we determined that it is more likely than not that the fair value of our one reporting unit exceeded its carrying amount, and
thus the impairment test was not required to be performed. Therefore, based on management’s review, no goodwill
impairment charge was required as of October 1, 2018. Historically, we have not recorded any goodwill impairment charges.

We are required to review long-lived assets and certain identifiable intangibles for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset might not be recoverable. Recoverability of assets to
be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows
expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is
measured by the amount by which the carrying amount of the asset exceeds its fair value. Assets to be disposed of are reported
at the lower of the carrying amount or fair value, less cost to sell.

Accounting for Income Taxes

Our provisions for federal, state, and foreign income taxes are calculated from consolidated income based on current
tax laws and any changes in tax rates from the rates used previously in determining the deferred tax assets and liabilities from
temporary differences between financial statement carrying amounts and amounts on our tax returns.

We recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences
between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax
assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are
expected to be recovered or settled. We evaluate our ability to benefit from all deferred tax assets and establish valuation
allowances for amounts we believe are not more likely than not to be realized.

We use a more-likely-than-not recognition threshold based on the technical merits of the income tax position taken
to evaluate uncertain tax positions. Uncertain tax positions that meet the more-likely-than-not recognition threshold are
measured in order to determine the tax benefit recognized in the financial statements. Penalties, if probable and reasonably
estimable, and interest expense related to uncertain tax positions are not recognized as a component of income tax expense
but recorded separately in indirect expenses or interest expense, respectively.

On December 20, 2017 the United States House of Representatives and the Senate passed the Tax Act which was
signed into law on December 22, 2017 and was generally effective beginning January 1, 2018. We were impacted in several
ways as a result of the Tax Act including, but not limited to, provisions which include a permanent reduction in the U.S.
federal corporate income tax rate from 35% to 21%, the revaluation of deferred tax assets and liabilities that was required as
a result of the tax rate change and the application of a mandatory one-time “transition tax” on unremitted earnings of certain
foreign subsidiaries that were previously tax deferred.

We re-measured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in
the future, which is now generally 26.4%. We completed our analysis of the Tax Act and finalized our provisional estimates,
which affected the measurement of these balances. Pursuant to Securities and Exchange Commission Staff Accounting
Bulletin 118 (“SAB 118”), the provisional amount recorded related to the re-measurement of the deferred tax balances has
been adjusted during the year ended December 31, 2018 as an increase in the provision for income taxes, including
adjustments to valuation allowances, of approximately $1.1 million.

The one-time “transition tax” imposed by the Tax Act is based on our total post-1986 earnings and profits (“E&P”)
which we had previously deferred from U.S. income taxation. We have completed the calculation of the total post-1986
foreign E&P and related foreign tax pools for these foreign subsidiaries. Further, the transition tax is based in part on the
amount of those earnings held in cash and other specified assets. This amount, as well as the related foreign tax credit
utilization, changed as we finalized our calculation of post-1986 foreign E&P and related foreign tax pools that were
previously deferred from U.S. federal taxation and the amounts held in cash or other specified assets. Similarly, the
cumulative foreign tax credit carry forward balance as of December 31, 2017 increased by approximately $2.2 million and
the valuation allowance required increased by approximately $2.2 million. No additional income taxes have been provided
for on any remaining undistributed foreign earnings not subject to the transition tax. No additional deferred taxes have been
provided for the $8.2 million of favorable outside basis differences inherent in these foreign entities because these amounts
continue to be permanently reinvested in foreign operations. Pursuant to SAB 118, the provisional amount recorded related
to the transition tax has been adjusted during the year ended December 31, 2018. We recognized this adjustment to the
provisional estimate as a decrease in the provision for income taxes of approximately $1.0 million during 2018.

The Tax Act subjects U.S. corporations to current tax on global intangible low-taxed income (or “GILTI”) earned by
certain foreign subsidiaries. The FASB Staff Q&A, Topic 740 No. 5, Accounting for Global Intangible Low-Taxed Income,
states that an entity can make an accounting policy election to either recognize deferred taxes for temporary differences
expected to reverse as GILTI in future years or provide for the tax expense related to GILTI resulting from those items in the
year the tax is incurred. We elected in the first quarter of fiscal year 2018 to recognize the resulting tax on GILTI as a period
expense in the period the tax is incurred, with no material effect on the consolidated financial statements. The current
provision for 2018 includes no tax expense for GILTI.

Stock-based Compensation

The ICF International, Inc. Omnibus Incentive Plans provide for the granting of stock options, stock appreciation
rights, restricted stock, restricted stock units (“RSUs”), performance shares, performance units, cash-based awards, and other
stock-based awards to all officers, key employees, and non-employee directors. On April 4, 2018, our board of directors
approved the 2018 Omnibus Incentive Plan (the “2018 Omnibus Plan”), which was subsequently approved by the
stockholders and became effective on May 31, 2018 (the “Effective Date”). The 2018 Omnibus Plan replaced the previous
2010 Omnibus Incentive Plan (the “Prior Plan”). As of December 31, 2018, there were approximately 1,098,906 shares
available for grant under the 2018 Omnibus Plan.

We utilize cash-settled RSUs (“CSRSUs”) which are settled only in cash payments. The cash payment is calculated
by multiplying the number of CSRSUs vested by our closing stock price on the vesting date, subject to a maximum payment
cap and a minimum payment floor. CSRSUs have no impact on the shares available for grant under the Omnibus Plan and
have no impact on the calculated shares used in earnings per share (“EPS”) calculations.

We began granting awards of registered shares to our non-employee directors on an annual basis under the 2018
Omnibus Plan in the third quarter of 2018. Previously, under the Prior Plan, we granted awards of unregistered shares to the
directors under the Annual Equity Election program. Those awards were issued from treasury stock and had no impact on the
shares available for grant under the Omnibus Plans.

We recognized total compensation expense relating to stock-based compensation of $19.6 million, $17.5 million, and
$15.9 million for the years ended December 31, 2018, 2017, and 2016, respectively. We recognize stock-based compensation
expense for stock options, restricted stock awards, and RSUs on a straight-line basis over the requisite service period, which
is generally the vesting period. We treat CSRSUs as liability-classified awards, and account for them at fair value based on
the closing price of our stock at the balance sheet date. We recognize expense for performance-based share awards (“PSAs”),
which are subject to a performance condition and a market condition, on a straight-line basis over the performance period.
Non-employee director awards are expensed over the performance period.

Stock-based compensation expense is based on the estimated fair value of these instruments and the estimated number
of shares ultimately expected to vest. The calculation of the fair value of the awards requires certain inputs that are subjective
and changes to the estimates used will cause the fair value of stock awards and related stock-based compensation expense to
vary. The fair value of stock options, restricted stock awards, RSUs, PSAs and non-employee director awards is estimated
based on the fair value of a share of common stock at the grant date. We have elected to use the Black-Scholes-Merton option
pricing model to determine the fair value of stock options. The fair value of a stock option award is affected by the price of
our stock on the date of grant, as well as other assumptions used as inputs in the valuation model. These assumptions include
the estimated volatility of the price of our stock over the term of the awards, the estimated period of time that we expect
employees will hold stock options, and the risk-free interest rate. The fair value of PSAs is estimated using a Monte Carlo
simulation model.

We are required to adjust stock-based compensation expense for the effects of estimated forfeitures of awards over
the expense recognition period. We estimate the rate of future forfeitures based on factors which include our historical
experience, but the amount of actual forfeitures may differ from current estimates particularly if the rate of future forfeitures
is different from previous experience. In addition, the estimation of PSAs that will ultimately vest requires judgment in terms
of estimates of future performance. To the extent actual forfeitures differ from estimated forfeitures and actual performance
or updated performance estimates differ from current estimates, such expense amounts are recorded as a cumulative
adjustment in the period the estimates are revised. See “Note 14—Accounting for Stock-based Compensation” in the “Notes
to Consolidated Financial Statements” for further discussion.

SELECTED KEY METRICS

In order to evaluate operations, we track revenue by key metrics that provide useful information about the nature of
our operations. Client markets provide insight into the breadth of our expertise. Client type is an indicator of the diversity of
our client base. Revenue by contract mix provides insight in terms of the degree of performance risk that we have assumed.
Significant variances in the key metrics tables that are provided below are discussed under the revenue section of the results
of operations.

Client markets

The following table shows revenue generated from client markets as a percent of total revenue for the periods
indicated. For each client, we have attributed all revenue from that client to the market we consider to be the client’s primary
market, even if a portion of that revenue relates to a different market. Certain minor revenue amounts reported in the prior
years have been reclassified within key market categories based on our current view of the client’s primary market in order
to increase comparability of the current year to prior years.

Our primary clients are the agencies and departments of the federal government and commercial clients. Most of our
revenue is from contracts on which we are the prime contractor, which we believe provides us strong client relationships. In
2018, 2017, and 2016, approximately 92%, 91%, and 90% of our revenue, respectively, was from prime contracts.

Contract mix

Contract mix varies from year to year due to numerous factors, including our business strategies and the procurement
activities of our clients. Unless the context requires otherwise, we use the term “contracts” to refer to contracts and any task
orders or delivery orders issued under a contract. There are three main types of contracts: time-and-materials contracts, fixed-
price contracts, and cost-based contracts. See detailed discussion of contract types in Critical Accounting Policies - Revenue
Recognition above.

The following table shows the approximate percentage of our revenue for each of these types of contracts for the
periods indicated. Certain immaterial revenue amounts in the prior years have been reclassified due to minor adjustments and
reclassification within contract type.

Payments to us on cost-based contracts with the federal government are provisional payments subject to adjustment
upon audit by the government. Such audits have been finalized through December 31, 2010, and any adjustments have been
immaterial. Contract revenue for subsequent periods has been recorded in amounts that are expected to be realized on final
audit and settlement of costs in those years.

Year ended December 31, 2018 compared to year ended December 31, 2017

Revenue. Revenue for the year ended December 31, 2018, was $1,338.0 million, compared to $1,229.2 million for
the year ended December 31, 2017, representing an increase of $108.8 million or 8.9%. The increase in revenue was
attributable to an increase in governmental revenue of $81.4 million or 10.6% and an increase in commercial revenue of $27.4
million or 6.0%. The growth in governmental revenue by client markets was driven by increases in revenue from energy,
environment, and infrastructure and safety and security clients, partially offset by our health, education, and social program
clients compared to the prior year. The changes in government revenue by client type were driven by the increases in state
(including territorial), from our disaster recovery clients, and local and international government revenues, partially offset by
a decline in federal government revenue. The increase in our commercial revenue by client market was driven by increases
in revenue from health, education, and social program, consumer and financial, and energy, environments and infrastructure
clients compared to the prior year. The increase in our revenues is partially attributable to revenue from acquired companies
of $15.6 million, which positively impacted our commercial clients ‘consumer and financial market and our government
clients ‘energy, environment and infrastructure market. As a result of the larger growth in government revenues compared to
the growth in commercial revenues, the governmental and commercial revenues as a percent of total revenue were 64% and
36% for the year ended December 31, 2018 compared with 62% and 38% for the prior year.

Direct costs. Direct costs for the year ended December 31, 2018, were $857.5 million compared to $771.7 million
for the year ended December 31, 2017, an increase of $85.8 million or 11.1%. The increase in direct costs year-over-year was
attributable to an increase in subcontractor and other direct costs of $67.3 million and an increase in direct labor and related
fringe costs of $18.5 million. Direct costs as a percent of revenue increased 1.3% to 64.1% for the year ended December 31,
2018, compared to 62.8% for the prior year. The increase in subcontractor and other direct costs was due to a change in the
mix of our services and other direct costs and an increased need for other direct costs to fulfill contract requirements. While
direct labor and related fringe costs increased by the $18.5 million, it decreased as a percent of revenue from 34.7% to 33.3%.

Changes in the mix of services and other direct costs provided under our contracts can result in variability in our
direct costs as a percentage of revenue. For example, when we perform work in the area of systems implementation, we
expect that more of our services will be performed in client-provided facilities. Such work generally has a higher staff
utilization than much of our current advisory work since the staff are dedicated to a single longer-term project, and we
anticipate decreased indirect expenses since our staff are working at the client facilities. In addition, to the extent we are
successful in winning larger contracts, while staff utilization generally increases, our own labor services component will
generally decrease because larger contracts typically are broader in scope and require more diverse capabilities, potentially
resulting in more subcontracted effort, more other direct costs, and lower margins. Although the duration of our contracts and
type of work may impact the ratio of direct costs as a percentage of revenue or gross margins, the economics of these larger
jobs are, nonetheless, generally favorable because they tend to increase income, broaden our revenue base, and have a
favorable return on invested capital.

Indirect and selling expenses. Indirect and selling expenses for the year ended December 31, 2018, were $361.0
million compared to $346.4 million for the prior year, an increase of $14.6 million or 4.2%. Indirect and selling expenses
increased due to increases in indirect labor and fringe of $10.2 million and in general and administrative expenses of $4.4
million. The increase in indirect labor and fringe is due in part to the increase in indirect labor and selling expenses from
acquired companies, higher costs to invest in our internal processes and infrastructure costs, costs added as a result of
acquisitions, an increase in bad debt due to a large customer filing bankruptcy, partially offset by a reduction in the incentive
compensation. Indirect and selling expenses as a percent of revenue decreased to 27.0% for the year ended December 31,
2018, compared to 28.2% for the year ended December 31, 2017.

Indirect and selling expenses generally include our management, facilities, and infrastructure costs for all employees
and the salaries and wages related to indirect activities, including stock-based and cash-based incentive compensation
provided to employees whose compensation and other benefit costs are included in indirect and selling expenses, plus
associated fringe benefits not directly related to client engagements.

Depreciation and amortization. Depreciation and amortization was $17.2 million for the year ended December 31,

2018, compared to $17.7 million for the prior year, a decrease of $0.5 million or 3.0%.

Amortization of intangible assets. Amortization of intangible assets for the year ended December 31, 2018 was $10.0
million compared to $10.9 million for the prior year. The $0.9 million decrease was primarily due to reduced levels of
intangible asset amortization associated with prior acquisitions, partially offset by an increase in amortization from current
acquisitions.

Operating income. For the year ended December 31, 2018, operating income was $92.3 million compared to $82.4
million for the prior year, an increase of $9.9 million or 12.0%. Operating income as a percent of revenue was 6.9% for the
year ended December 31, 2018 compared to 6.7% for the prior year largely due to the increase in gross profits of $23.0
million, offset by higher indirect and selling expenses of $14.6 million.

Interest expense. For the year ended December 31, 2018, interest expense was $8.7 million, compared to $8.6 million

for the prior year, an increase of $0.1 million or 1.8%.

Other (expense) income. For the year ended December 31, 2018, other expense was $0.7 million compared to other
income of $0.1 million for the prior year. The change was primarily due to net unrealized and realized foreign losses of $0.6
million for the year ended December 31, 2018 compared to net unrealized and realized gains of $0.2 million for the year
ended December 31, 2017.

Provision for income taxes. The effective income tax rate for the years ended December 31, 2018 and December 31,
2017, was 25.9% and 15.0%, respectively. The increase in the rate for 2018 was primarily related to one-time favorable
adjustments of $16.2 million recorded in 2017 related to the enactment of the Tax Act in December 2017. As a result, we
were required to make favorable provisional adjustments for revaluing our deferred tax assets and liabilities and permanent
non-taxable income that were partially offset by the “transition tax” and establishment of a valuation allowance on certain
deferred tax assets. Our effective tax rate, including state and foreign taxes net of federal benefit for the year ended December
31, 2018 was lower than the statutory tax rate for the year primarily due to tax benefits for stock-based compensation, and
state tax credits partially offset by the establishment of a valuation allowance on certain deferred tax assets, permanent
differences related to compensation costs and other expenses not deductible for tax purposes.

We account for the expected impact of discrete tax items once we determine that they are both reasonably quantified
and we are confident they will be realized due to the associated event occurring (such as the filing of an amended tax return,
enactment of tax legislation, or the closure of an audit examination).

Year ended December 31, 2017 compared to year ended December 31, 2016

Revenue. Revenue for the year ended December 31, 2017, was $1,229.2 million, compared to $1,185.1 million for
the prior year, representing an increase of $44.1 million or 3.7%. The increase in revenue was attributable to increases in
commercial revenue of $46.7 million, partially offset by a decrease in government revenue of $2.6 million compared to the
prior year. The growth in commercial revenue was driven by increases in our revenue from our energy, environment, and
infrastructure and health, education, and social programs clients. The decline in government revenues was due to a decrease
in health, education, and social programs clients, partially offset by increases in revenue from our energy, environment, and
infrastructure and safety and security government clients. As a result of these changes the governmental and commercial
revenues as a percent of total revenue were 62% and 38% for the year ended December 31, 2017 compared with 65% and
35% for the prior year.

Direct costs. Direct costs for the year ended December 31, 2017, were $771.7 million compared to $745.1 million
for the prior year, an increase of $26.6 million or 3.6%. The increase in direct costs year-over-year was attributable to an
increase in both subcontractor and other direct costs of $24.6 million and an increase in direct labor and related fringe costs
of $2.0 million. Direct costs as a percent of revenue decreased 0.1% to 62.8% for the year ended December 31, 2017,
compared to 62.9% for the prior year. This decrease was due to the decrease in direct labor and related fringe costs (a 1.1%
decrease as a percent of revenue), offset by an increase in subcontractor and other direct costs (a 1.0% increase as a percent
of revenue). The decrease in direct labor and fringe costs is the result of a change in our labor allocation. Effective January
1, 2017, in order to be consistent with updated cost accounting requirements under U.S. government cost accounting
standards, we changed our labor cost allocation methodology for all contracts which resulted in the classification of certain
labor and associated fringe costs as indirect and selling expenses rather than direct costs. In comparing the results of
operations for the year ended December 31, 2017 to the prior year, this change in labor allocation methodology resulted in
the classification of an estimated $9.5 million of indirect and selling expenses as direct costs in the prior year.

Indirect and selling expenses. Indirect and selling expenses for the year ended December 31, 2017, were $346.4
million compared to $328.0 million for the prior year, an increase of $18.4 million or 5.6%. Indirect and selling expenses
increased due to an increase in indirect labor and fringe of $12.0 million, which was due, in part, to the change in labor cost
allocation described above, as well as an increase in incentive compensation of $4.4 million, of which $3.0 million was an
increase in cash bonuses to take advantage of tax rate differentials, and an increase in other indirect costs of $2.0 million. In
response to the Tax Act that was passed in December 2017, we increased the portion of bonuses that will be paid in cash,
which resulted in an acceleration of incentive compensation expense for the year as opposed to recording the expense as
equity awards vest. The increase in cash bonus expense as a proportion of incentive compensation increased the amount that
can be deducted for income tax purposes for 2017 due to the higher corporate tax rate. The increase in other indirect costs
was primarily due to $1.7 million of facility consolidations related to reductions in office space utilized at our corporate and
U.K offices. Indirect and selling expenses as a percent of revenue increased to 28.2% for the year ended December 31, 2017,
compared to 27.7% for the prior year.

Depreciation and amortization. Depreciation and amortization was $17.7 million for the year ended December 31,
2017, compared to $16.6 million for the prior year, an increase of $1.1 million or 6.3%. Depreciation and amortization
increased due to higher levels of depreciation and amortization from the continued investment in capital expenditures of
property and equipment and costs of internal use software.

Amortization of intangible assets. Amortization of intangible assets for the year ended December 31, 2017 was $10.9
million compared to $12.5 million for the prior year. The $1.6 million decrease was primarily due to reduced levels of
intangible asset amortization associated with prior acquisitions.

Operating income. For the year ended December 31, 2017, operating income was $82.4 million compared to $82.8
million for the prior year, a decrease of $0.4 million or 0.5%. Operating income as a percent of revenue was 6.7% for the
year ended December 31, 2017 compared to 7.0% for the prior year largely due to the increase in indirect expenses offset by
lower amortization of intangible assets.

Interest expense. For the year ended December 31, 2017, interest expense was $8.6 million, compared to $9.5 million
for the prior year a decrease of $0.9 million or 9.7%. The decrease was primarily due to lower average debt balances
outstanding for the year compared to the prior year, partially offset by a slight increase in our weighted average interest rate
compared to the same period in 2016 and additional amortization of unamortized loan costs related to the Credit Facility
modification.

Other (expense) income. For the year ended December 31, 2017, other income was $0.1 million compared to other
income of $1.2 million for the prior year. Other income for the year ended December 31, 2017, which primarily represents
foreign currency gains primarily offset by the loss on disposal of fixed assets, compared to other income for the prior
year. The net gain on a corporate owned insurance policy impacted other income during the prior year 2016.

Provision for income taxes. The effective income tax rate for the years ended December 31, 2017 and December 31,

2016, was 15.0% and 37.5%, respectively.

The decrease in the rate for 2017 was primarily related to favorable net adjustments of $16.2 million related to the
enactment of the Tax Act in December 2017. As a result, we were required to make favorable provisional adjustments for
revaluing our deferred tax assets and liabilities and permanent non-taxable income that were partially offset by the “transition
tax” and establishment of a valuation allowance on certain deferred tax assets. Our effective tax rate, including state and
foreign taxes net of federal benefit, for the year ended December 31, 2017 was lower than the statutory tax rate for the year
primarily due to the net favorable adjustments for the impact of the Tax Act, tax benefits for stock-based compensation,
permanently non-taxable income, and state tax credits partially offset by the establishment of a valuation allowance on certain
deferred tax assets, permanent differences related to compensation costs and other expenses not deductible for tax purposes.
We account for the expected impact of discrete tax items once we determine that they are both reasonably quantified and we
are confident they will be realized due to the associated event occurring (such as the filing of an amended tax return, enactment
of tax legislation, or the closure of an audit examination).

NON-GAAP MEASURES

These following tables provide reconciliations of financial measures that are not U.S. GAAP (“non-GAAP) to the
most applicable U.S. GAAP measures. While we believe that these non-GAAP financial measures may be useful in evaluating
our financial information, they should be considered supplemental in nature and not as a substitute for financial information
prepared in accordance with U.S. GAAP. Other companies may define similarly titled non-GAAP measures differently and,
accordingly, care should be exercised in understanding how we define these measures.

Service Revenue. Service revenue represents revenue less subcontractor and other direct costs (which include third-
party materials and travel expenses). Service revenue is not a recognized term under U.S. GAAP and should not be considered
an alternative to revenue as a measure of operating performance. This presentation of service revenue may not be comparable
to other similarly titled measures used by other companies because other companies may use different methods to prepare
similarly titled measures. We believe service revenue is a useful measure to investors since, as a consulting firm, a key source
of our profit is revenue obtained from the services that we provide to our clients through our employees.

The table below presents a reconciliation of revenue to service revenue for the periods indicated:

EBITDA and Adjusted EBITDA. EBITDA, or earnings before interest and other income and/or expense, tax, and
depreciation and amortization, is a measure that we use to evaluate our performance. We believe EBITDA is useful to
investors because similar measures are frequently used by securities analysts, investors, and other interested parties in
evaluating companies in our industry by providing a view of a company’s operations before the impact of capital budgeting,
tax strategy and capital structure decisions. Adjusted EBITDA is EBITDA further adjusted to eliminate the impact of certain
items that we do not consider to be indicative of the performance of our ongoing operations. We evaluate these adjustments
on an individual basis based on both the quantitative and qualitative aspects of each respective item, which include its size
and whether or not we expect it to occur as part of our normal business on a regular basis. We believe that the adjustments
applied in calculating adjusted EBITDA are reasonable and appropriate to provide additional information related to our
operating performance.

EBITDA and adjusted EBITDA are not recognized terms under U.S. GAAP and do not purport to be an alternative
to net income as a measure of operating performance, or to cash flows from operating activities as a measure of liquidity.
Because not all companies use identical calculations, this presentation of EBITDA and adjusted EBITDA may not be
comparable to other similarly-titled measures used by other companies. EBITDA and adjusted EBITDA are not intended to
be a measure of free cash flow for management’s discretionary use, as they do not consider certain cash requirements, such
as interest payments, tax payments, capital expenditures, and debt service.

Special charges related to acquisitions. These costs are mainly related to closed and anticipated-to-close acquisitions, consisting primarily of
consultants and other outside party costs, an increase in the contingent consideration liability and amortization of deferred consideration payments,
discounted as part of the acquisition.

Special charges related to severance for staff realignment: These costs are due to involuntary employee termination benefits for Company officers
or groups of employees who have been terminated as part of a consolidation or reorganization.

Special charges related to facilities consolidations and office closures: These costs are exit costs associated with terminated leases or full office
closures. These exit costs include charges incurred under a contractual obligation that existed as of the date of the accrual and for which we will
continue to pay until the contractual obligation is satisfied but with no economic benefit to us.

Special charges due to additional cash bonus expense: In response to the Tax Act, we increased the portion of bonuses that will be paid in cash,
which increased the amount that can be deducted for income tax purposes for 2017.

(5)

Special charge related bad debt reserve. This cost is related to the January 2019 bankruptcy filing of a utility client.

Non-GAAP EPS. Non-GAAP EPS represents diluted EPS excluding the impact of certain items (such as special
charges and acquisition-related expenses) that we do not consider to be indicative of the performance of our ongoing
operations and are excluded from adjusted EBITDA as described above. Diluted EPS has also been adjusted to eliminate the
impact of amortization of intangible assets related to our acquisitions since the impact is larger following an acquisition and,
depending on when the acquisition occurred, impacts comparability. Non-GAAP EPS is not a recognized term under U.S.
GAAP and does not purport to be an alternative to basic or diluted EPS. Because not all companies use identical calculations,
the presentation of non-GAAP EPS may not be comparable to other similarly titled measures used by other companies. We
believe that the supplemental adjustments applied in calculating non-GAAP EPS are reasonable and appropriate to provide
additional information to investors.

A reconciliation of diluted EPS to non-GAAP EPS, including income tax effects calculated using an effective U.S.
GAAP tax rate of 25.9%, 15.0% (or 37.0% effective tax rate for the period prior to any adjustments for the new tax regulation),
and 37.5%, respectively, follows:

LIQUIDITY AND CAPITAL RESOURCES

Liquidity and Borrowing Capacity. Our business generally requires minimal infrastructure investment because we
are primarily a service provider for which facilities requirements are provided for under operating leases or on client premises.
Short-term liquidity requirements are created by our use of funds for working capital, capital expenditures, and the need to
provide any debt service. We expect to meet these requirements through a combination of cash flows from operations and
borrowings under our Fifth Amended and Restated Business Loan and Security Agreement with a syndicate of eleven
commercial banks (the “Credit Facility”).

We anticipate that our long-term liquidity requirements, including any future acquisitions, will be funded through a
combination of cash flows from operations, borrowings under our Credit Facility, additional secured or unsecured debt, or
the issuance of common stock, each of which may be initially funded through borrowings under our Credit Facility.

We believe that the combination of internally generated funds, available bank borrowings under our Credit Facility,
and cash and cash equivalents on hand will provide the required liquidity and capital resources necessary to fund on-going
operations, customary capital expenditures, and other current working capital requirements. We are continuously analyzing
our capital structure to ensure we have sufficient capital to fund internal growth, repurchase of common stock and fund future
acquisitions. We monitor the state of the financial markets on a regular basis to assess the availability and cost of additional
capital resources both from debt and equity sources. We believe that we will be able to access these markets at commercially
reasonable terms and conditions if we need additional borrowings or capital.

Financial Condition. There were several changes in our balance sheet during the year ended December 31, 2018.
Cash and cash equivalents decreased slightly to $11.7 million on December 31, 2018, from $11.8 million on December 31,
2017. Restricted cash (current and non-current) decreased $11.2 million to $1.3 million at December 31, 2018. The decrease
in restricted cash is due to funds that were held in escrow at the end of 2017 related to our acquisition of TFC, which was
subsequently completed in January 2018 and is discussed in “Acquisitions and Business Combinations” section above.

Contract receivables are the principal component of our working capital and generally increase due to revenue growth
and may be favorably or unfavorably impacted by our collections efforts, including timing from new contract startups, and
other short-term fluctuations related to the payment practices of our clients.

Contract assets and contract liabilities represent contract costs in excess of billings, and billings in excess of costs,
respectively, both of which arise from timing of billings on our contracts with customers. At December 31, 2018, contract
assets and contract liabilities were $126.7 million and $33.5 million, respectively, compared to $123.2 million and $38.6
million, respectively, at December 31, 2017. Total accounts receivable consists of billed receivables net of allowance for
doubtful accounts. We evaluate our collections efforts using the days sales outstanding ratio, or DSO, which we calculate by
dividing total accounts receivable, net of deferred revenues, by revenue per day. DSO for the year ended December 31, 2018
was 77 days compared to 71 days during the prior year with the increase occurring largely due to disaster recovery work that
began in 2018.

Property and equipment, net of depreciation and amortization, increased due to capital expenditures primarily related
to increases in capitalized software as we invest in our infrastructure as well as in other asset accounts related to recent
acquisitions.

Goodwill and intangible assets increased due to recent acquisitions. As a result of the three acquisitions that occurred
in 2018, we recognized the fair value of the assets and liabilities assumed and allocated $32.1 million to goodwill, $10.6
million to intangible assets and $1.2 million to estimated fair value of contingent consideration to be paid to the former owners
on the achievement of certain objectives. The intangible assets primarily consist of customer relationships and are amortized
on an accelerated basis based on forecasted customer cash payments. We determined the fair value of the contingent
consideration as of the acquisition date using a valuation model which included the most likely outcome and the application
of an appropriate discount rate. At December 31, 2018, the fair value of the contingent consideration was remeasured and a
charge of $0.5 million was incurred due to the increase in the contingent liability.

Accounts payable, accrued salaries and benefits, accrued subcontractors and other direct costs, and accrued expenses
and other current liabilities increased to $102.6 million, $44.1 million, $58.8 million and $39.1 million, respectively, on
December 31, 2018 from $75.1 million, $45.6 million, $47.5 million, and $17.6 million on December 31, 2017, respectively.
The increases in the liabilities are due primarily to timing of payments in the fourth quarter of 2018, the increased activity in
the fourth quarter and, to a lesser extent, the impact of the acquired companies.

Long-term debt decreased to $200.4 million on December 31, 2018, from $206.3 million on December 31, 2017, due
to net payments on our Credit Facility of $5.8 million. The weighted average debt balance on the credit facility for the years
ended December 31, 2018 and 2017 was $237.0 million and $259.4 million. The weighted average interest rate on the Credit
Facility for the years ended December 31, 2018 and 2017 was 3.29% and 2.65%.

On August 8, 2018, we entered into two floating-to-fixed interest rate hedging agreements for an aggregate notional
amount of $75.0 million to hedge a portion of our Credit Facility. We entered into the hedge to help manage the risk related
to interest rate volatility and designated the swap as a cash flow hedge. The cash flows from the hedge began on August 31,
2018 and the swap matures August 31, 2023. The hedging agreements add to the agreement that we had entered into in
2017. At December 31, 2018, the aggregate notional amount hedged totaled $100.0 million, excluding the hedge sold on
December 1, 2016.

Treasury stock increased to $139.7 million on December 31, 2018 from $121.5 million on December 31, 2017

primarily due to share buybacks under our share repurchase plan and from vesting of stock-based awards of $18.3 million.

The increase in accumulated other comprehensive loss of $7.5 million was driven by $6.7 million due to the change
in the value of certain foreign currencies relative to the U.S. dollar (primarily the British Pound, Euro and Canadian dollar)
and by the change in the fair value of the interest rate hedging agreement as described above, and $0.8 million due to the
adoption of new accounting principle in 2019 (see Note 2—Summary of Significant Accounting Policies” in the “Notes to
Consolidated Financial Statements.”)

We have explored various options of mitigating the risk associated with potential fluctuations in the foreign currencies
in which we conduct transactions. We currently have hedges in an amount proportionate to work anticipated to be performed
under certain contracts in Europe. We recognize changes in the fair-value of the hedges in our results of operations. We may
increase the number, size and scope of our hedges as we analyze options for mitigating our foreign exchange and interest rate
risk. The current impact of the foreign currency hedges to the consolidated financial statements is immaterial.

Cash Flows. We consider cash on deposit and all highly liquid investments with original maturities of three months
or less when purchased to be cash and cash equivalents. The following table sets forth our sources and uses of cash for the
following years.

Our operating cash flows are primarily affected by the overall profitability of our contracts, our ability to invoice and
collect from our clients in a timely manner, and the timing of vendor and subcontractor payments in accordance with
negotiated payment terms. We bill most of our clients on a monthly basis after services are rendered.

Comparing the net cash provided by operating activities for December 31, 2018 and 2017, cash flows from operating
activities for 2018 were positively impacted by net income, the adjustments to reconcile net income to net cash provided by
operating activities for non-cash expenses, such as depreciation, equity compensation and deferred income taxes, the change
in accrued expenses and accounts payable, and the use of tax deposits to satisfy tax liabilities. The cash flows from operations
were negatively impacted by the change in contract receivables and net contract assets and liabilities. The increase in 2018
for the adjustment for the non-cash deferred taxes was the result of the 2017 impact of the Tax Act, the revaluation of the
deferred taxes in 2017 related to the change in tax rates and to our continued use of equity compensation. The positive impact
upon cash flows from operations due to changes in the accrued expenses and accounts payable is due to the timing of payment
of current liabilities and the commencement of new, large contracts in the latter part of the year increasing the volume and
activity. The negative impact upon cash flow from operations due to the change in contract receivables and net contract assets
and liabilities was also due to the commencement of large disaster recovery contracts in the latter part of the year. We evaluate
our collections efforts using the day’s sales outstanding ratio, or DSO, which we calculate by dividing total accounts
receivable, net of deferred revenues, by revenue per day. DSO for the year ended December 31, 2018 were 77 days compared
to 71 days during the prior year.

Comparing the net cash provided by operating activities for December 31, 2017 and 2016, cash flows from operating
activities for 2017 were positively impacted by net income, the change in contract receivables and net contract assets and
liabilities, and the changes in accrued expenses, and accounts payable. The cash flows from operations was negatively
impacted by the adjustments to reconcile net income to net cash flow provided by operations and the adjustment for deferred
taxes. The change in contract receivables and net contract assets and liabilities was due to the significantly improved DSO
metric on a year over year basis. DSO for the year ended December 31, 2017 improved to 71 days compared to 78 days
during the prior year. The negative impact upon the adjustment for deferred taxes is a result of a non-cash adjustment of the
deferred tax liabilities due to the decrease in the effective tax rate from the Tax Act.

Our cash flows used in investing activities consists primarily of capital expenditures and acquisitions. During the
year ended 2018, we purchased capital assets totaling $21.8 million and had payments for business acquisitions of $34.6
million, net of cash received. During the year ended 2017, we purchased capital assets totaling $14.5 million. During the year
ended 2016, we purchased capital assets totaling $13.8 million.

Our cash flows used in and provided by financing activities consists primarily of debt and equity transactions. For
the year ended 2018, cash flows used in financing activities were primarily due to net payments on our Credit Facility of $5.8
million, dividends paid of $7.9 million, and share repurchases under our share repurchase plan of $13.9 million. For the year
ended 2017, cash flows used in financing activities were primarily due to net payments on our Credit Facility of $53.1 million,
and share repurchases under our share repurchase plan of $30.7 million. For the year ended 2016, cash flows used in financing
activities were primarily due to net payments on our Credit Facility of $52.1 million, and share repurchases under our share
repurchase plan of $11.9 million.

OFF-BALANCE SHEET ARRANGEMENTS

Contractual Obligations

We use off-balance sheet arrangements to finance the lease of office and storage facilities through operating leases.
Operating leases are also used from time to time to finance the use of computers, servers, copiers, telephone systems, and, to
a lesser extent, other fixed assets (such as furnishings). Additionally, we also may obtain additional operating leases in
connection with business acquisitions. We generally assume the lease rights and obligations of businesses acquired in
business combinations and continue financing facilities and equipment under operating leases until the end of the lease term
following the acquisition date.

In addition, we also had eleven outstanding letters of credit provided for under our Credit Facility with a total value

of $3.3 million, primarily related to deposits to support our facility leases.

The following table summarizes our contractual obligations as of December 31, 2018 that require us to make future
cash payments. Our summary of contractual obligations includes payments that we have an unconditional obligation to make.

Represents the obligation for principal and variable interest payments related to the Credit Facility assuming the principal amount outstanding and
interest rates at December 31, 2018 remain fixed through maturity. These assumptions are subject to change in future periods.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to certain financial market risks, the most predominant being fluctuations in interest rates for

borrowings under the Credit Facility and foreign exchange rate risk.

We monitor interest rate fluctuations and outlook as an integral part of our overall risk management program, which
recognizes the unpredictability of financial markets and seeks to reduce potentially adverse effects of higher interest rates on
our results of operations. As part of this strategy, we may use interest rate swap arrangements to hedge all or a portion of our
interest rate risk by securing hedges that effectively convert our variable rate debt to fixed rate debt. We do not use such
instruments for speculative or trading purposes. Our exposure to market risk includes changes in interest rates for borrowings
under the Credit Facility. These borrowings accrue interest at variable rates. Based on our borrowings under this facility and
amount of hedging in 2018, a 1% increase in interest rates would have increased interest expense by approximately $2.4
million, pre-tax, and would have decreased our annual net income and operating cash flows by a comparable amount.

As a result of conducting business in currencies other than the U.S. dollar, we are subject to market risk with respect
to adverse fluctuations in currency exchange rates. In general, our currency risk is mitigated largely by matching costs with
revenues in a given currency. However, our exposure to fluctuations in other currencies against the U.S. dollar increases as a
greater portion of our revenue is generated in currencies other than the U.S. dollar. We currently have hedges in place to
mitigate our foreign exchange risk related to our operations in Europe; however, given the amount of business conducted in
Europe, there is some risk that revenue and profits will be affected by foreign currency exchange fluctuations. We use a
sensitivity analysis to assess the impact of movement in foreign currency exchange rates on revenue. During the year ended
December 31, 2018, 14.8% of our revenue was generated from our international operations based on the location to which a
contract was awarded. As a result, a 10% increase or decrease in the value of the U.S. dollar against all currencies would
have an estimated impact on revenue of approximately 1.5%, or $19.8 million. Actual gains and losses in the future could
differ materially from this analysis based on the timing and amount of both foreign currency exchange rate movements and
our actual exposure. As of December 31, 2018, we held approximately $11.9 million in cash in foreign bank accounts to be
utilized on behalf of our foreign subsidiaries, thereby partially mitigating foreign currency conversion risks.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures. Based on an evaluation under the supervision and with the
participation of the Company’s management, the Company’s principal executive officer and principal financial officer have
concluded that the Company’s disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the
Exchange Act, were effective as of December 31, 2018 to provide reasonable assurance that information required to be
disclosed by the Company in reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized
and reported within the time periods specified in the SEC rules and forms and (ii) accumulated and communicated to the
Company’s management, including its principal executive officer and principal financial officer, as appropriate to allow
timely decisions regarding required disclosure.

Management’s Annual Report on Internal Control Over Financial Reporting. The Company’s management is
responsible for establishing and maintaining adequate internal control over financial reporting (as such term is defined in
Exchange Act Rules 13a-15(f) and 15d-15(f)). Management conducted an assessment of the effectiveness of the Company’s
internal control over financial reporting based on the criteria set forth in the 2013 Internal Control—Integrated Framework
issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on the assessment,
management has concluded that its internal control over financial reporting was effective as of December 31, 2018. The
Company’s independent registered public accounting firm, Grant Thornton LLP, has issued an audit report on the Company’s
internal control over financial reporting, which appears on page F-2 of this Form 10-K.

The Company’s internal control over financial reporting is designed to provide reasonable assurance regarding the
reliability of financial reporting, and the preparation of financial statements for external purposes in accordance with U.S.
GAAP. The Company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the
maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the
Company’s assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of
financial statements in accordance with U.S. GAAP; (iii) that the Company’s receipts and expenditures are being made only
in accordance with authorizations of the Company’s management and directors; and (iv) 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.

Changes in Internal Control Over Financial Reporting. There were no material changes in our internal control over
financial reporting during 2018, which were identified in connection with management’s evaluation required by paragraph
(d) of Rules 13a-15 and 15d-15 under the Exchange Act, that have materially affected, or are reasonably likely to materially
affect, the Company’s internal control over financial reporting.

Inherent Limitations Over Internal Controls. A control system, no matter how well designed 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 evaluation of internal controls can provide absolute
assurance that all control issues and instances of fraud, if any, have been detected. Because of the inherent limitations in any
control system, misstatements due to error or fraud may occur and may not be detected. Also, any evaluations of the
effectiveness of controls in future periods are subject to the risk that those internal controls may become inadequate because
of changes in business conditions, or that the degree of compliance with the policies or procedures may deteriorate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders
ICF International, Inc.

Opinion on the financial statements
We have audited the accompanying consolidated balance sheets of ICF International, Inc. (a Delaware corporation) and
subsidiaries (the “Company”) as of December 31, 2018 and 2017, the related consolidated statements of comprehensive
income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2018, and the
related notes (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 also have 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 the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway
Commission (“COSO”), and our report dated February 27, 2019 expressed an unqualified opinion.

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 supporting 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.

We have served as the Company’s auditor since 2000.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders
ICF International, Inc.

Opinion on internal control over financial reporting
We have audited the internal control over financial reporting of ICF International, Inc. (a Delaware corporation) and
subsidiaries (the “Company”) as of December 31, 2018, based on criteria established in the 2013 Internal Control—Integrated
Framework 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 the 2013 Internal Control—Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States)
(“PCAOB”), the consolidated financial statements of the Company as of and for the year ended December 31, 2018, and our
report dated February 27, 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
Annual 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.

ICF International, Inc. and Subsidiaries

Notes to Consolidated Financial Statements
(dollar amounts in tables in thousands, except share and per share data)

NOTE 1 - BASIS OF PRESENTATION AND NATURE OF OPERATIONS

Basis of Presentation and Nature of Operations

The accompanying consolidated financial statements include the accounts of ICF International, Inc. (“ICFI”) and its
principal subsidiary, ICF Consulting Group, Inc. (“Consulting,” and together with ICFI, “the Company”), and have been
prepared in accordance with United States (“U.S.) generally accepted accounting principles (“U.S. GAAP”). Consulting is a
wholly owned subsidiary of ICFI. ICFI is a holding company with no operations or assets other than its investment in the
common stock of Consulting. All other subsidiaries of the Company are wholly owned by Consulting. All significant
intercompany transactions and balances have been eliminated.

Nature of Operations

The Company provides professional services and technology-based solutions to government and commercial clients,
including management, technology, and policy consulting and implementation services, in the areas of energy, environment,
and infrastructure; health, education, and social programs; safety and security; and consumer and financial. The Company
offers a full range of services to these clients throughout the entire life cycle of a policy, program, project, or initiative, from
research and analysis and assessment and advice to design and implementation of programs and technology-based solutions,
and the provision of engagement services and programs.

The Company’s major clients are U.S. federal government departments and agencies, most significantly the
Department of Health and Human Services, Department of State and Department of Defense. The Company also serves U.S.
state (including territories) and local government departments and agencies, international governments, and commercial
clients worldwide. Commercial clients include airlines, airports, electric and gas utilities, oil companies, banks and other
financial services companies, transportation, travel and hospitality firms, non-profits/associations, law firms, manufacturing
firms, retail chains, and distribution companies. The term “federal” or “federal government” refers to the U.S. federal
government, and “state and local” or “state and local government” refers to U.S. state (including territories) and local
governments, unless otherwise indicated.

The Company, incorporated in Delaware, is headquartered in Fairfax, Virginia. It maintains offices throughout the
world, including over 65 offices in the U.S. and U.S. territories and more than 15 offices in key markets outside the U.S.,
including offices in the United Kingdom, Belgium, China, India and Canada.

Reclassifications

Certain amounts in the 2017 and 2016 consolidated financial statements have been reclassified to conform to the

current year presentation.

As a result of the adoption of Accounting Standard Update (“ASU”) 2014-09, Revenue from Contracts with
Customers (Topic 606), the Company presented balances, titled contract assets and contract liabilities, within the consolidated
balance sheet as well as the net impact of changes in these balances within the consolidated statement of cash flows. The
Company reclassified comparable balances within the December 31, 2017 consolidated balance sheet as well as the impact
of changes in these balances within the 2017 and 2016 consolidated statement of cash flows in order to enhance comparability.
Any other reclassifications were immaterial to the financial statements taken as a whole.

F-7

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and
assumptions that affect the reported amounts of assets, liabilities, and contingent liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from
those estimates.

Revenue Recognition

The Company primarily provides services and technology-based solutions for clients that operate in a variety of
markets and the solutions may span the entire program life cycle, from initial research and analysis to the design and
implementation of solutions. The Company enters into agreements with clients that create enforceable rights and obligations
and for which it is probable that the Company will collect the consideration to which it will be entitled as services and
solutions are transferred to the client. Except in certain narrowly defined situations, the Company’s agreements with its clients
are written and revenue is generally not recognized on oral or implied arrangements. The Company recognizes revenue based
on the consideration specified in the applicable agreement and excludes from revenue amounts collected on behalf of third
parties. Accordingly, sales and similar taxes which are collected on behalf of third parties are excluded from the transaction
price.

The Company evaluates whether two or more agreements should be accounted for as one single contract and whether
combined or single agreements should be accounted for as more than one performance obligation. For most contracts, the
client requires the Company to perform a number of tasks in providing an integrated output for which the client has contracted,
and, hence, contracts of this type are tracked as having only one performance obligation since a substantial part of the
Company’s promise is to ensure the individual tasks are incorporated into a combined output in accordance with contract
requirements. When contracts are separated into multiple performance obligations, the Company allocates the total
transaction price to each performance obligation based on the estimated relative standalone selling prices of the promised
services underlying each performance obligation. The Company generally provides customized solutions in which the pricing
is based on specific negotiations with each client, and, in these cases, the Company uses a cost-plus margin approach to
estimate the standalone selling price of each performance obligation. It is common for the Company’s long-term contracts to
contain award fees, incentive fees or other provisions that can either increase or decrease the transaction price. These variable
amounts are generally awarded at the completion of a contractually-stipulated performance assessment period based on the
achievement of performance metrics, program milestones or cost targets, and the amount awarded may be subject to client
discretion. The Company estimates variable consideration as the most likely amount to which the Company expects to be
entitled.

The Company evaluates contractual arrangements to determine whether revenue should be recognized on a gross
versus net basis. The Company’s assessment is based on the nature of the promise to the client. In most cases, the Company
itself agrees to provide specified services to the client as a principal and revenue is recognized on a gross basis. In rare cases,
the Company acts as an agent and merely arranges for another party to provide services to the client and revenue is recognized
on a net basis in reflection of the fact that the Company does not control the goods or services provided to the client by the
other party.

Long-term contracts typically contain billing terms that provide for invoicing once a month and payment on a net 30-
day basis. Exceptions to monthly billing terms are to ensure that the Company performs satisfactorily rather than representing
a significant financing component. For cost-based contracts, for example, the Company’s performance is evaluated during a
contractually stipulated performance period and, while contract costs may be billed on a monthly basis, the Company is
generally permitted to bill for incentive or award fees only after the completion of the performance assessment period, which
may occur quarterly, semi-annually or annually, and after the client completes the performance assessment. Similarly, fixed-
price contracts, in order to ensure that the Company meets contract requirements, may provide for milestone billings based
on the attainment of specific project objectives rather than for billing on a monthly basis. Moreover, contracts may require
retentions or hold backs that are paid at the end of the contract to ensure that the Company performs in accordance with
requirements. The Company does not assess whether a contract contains a significant financing component if the Company
expects, at contract inception, that the period between payment by the client and the transfer of promised services to the client
will be one year or less.

As a service provider, the Company generally recognizes revenue over time as control is transferred to a client, based
on the extent of progress towards satisfaction of the performance obligation. The selection of the method used to measure
progress requires judgment and is dependent, among other factors, on the contract type selected by the client during contract
negotiation and the nature of the services and solutions to be provided.

F-8

When a performance obligation is billed using a time-and-materials contract type, the Company uses output progress
measures to estimate revenue earned based on hours worked in contract performance at negotiated billing rates. Fixed-price
level-of-effort contracts are substantially similar to time-and-materials contracts except that the Company is required to
deliver a specified level of effort over a stated period of time. For these contracts, the Company estimates revenue earned
using contract hours worked at negotiated bill rates as the Company delivers the contractually required workforce.

For cost-based contracts, the Company recognizes revenue based on contract costs incurred, as the Company becomes
contractually entitled to reimbursement of the contract costs, plus a most likely estimate of award or incentive fees earned on
those costs even though final determination of fees earned occurs after the contractually-stipulated performance assessment
period ends.

For performance obligations requiring the delivery of a service for a fixed price, the Company uses the ratio of actual
costs incurred to total estimated costs, provided that costs incurred (an input method) represents a reasonable measure of
progress towards the satisfaction of a performance obligation, in order to estimate the portion of total revenue earned. This
method provides a faithful depiction of the transfer of value to the client when the Company is satisfying a performance
obligation that entails integration of tasks for a combined output which requires the Company to coordinate the work of
employees, subcontractors and delivery of other contract costs. Contract costs that are not reflective of the Company’s
progress to satisfying a performance obligation are not included in the calculation of the measure of progress. When this
method is used, changes in estimated costs to complete these obligations result in adjustments to revenue on a cumulative
catch-up basis, which causes the effect of revised estimates for prior periods to be recognized in the current period. Changes
in these estimates can routinely occur over contract performance for a variety of reasons, which include: changes in contract
scope; changes in contract cost estimates due to unanticipated cost growth or reassessments of risks impacting costs; changes
in estimated incentive or award fees; or performing better or worse than previously estimated.

In some fixed price service contracts, the Company performs services of a recurring nature, such as maintenance and
other services of a “stand ready” nature. For these contracts, the Company has the right to consideration in an amount that
corresponds directly with the value that the client has received. Therefore, the Company records revenue on a time elapsed
basis to reflect the transfer of control to the client throughout the contract.

Contracts are often modified to reflect changes in contract specifications and requirements, and these changes may
create new enforceable rights and obligations. Most modifications are for services that are not distinct from the existing
agreement due to the significant integration service that the Company provides. Therefore, most modifications are accounted
for as part of an existing performance obligation. The effect of these modifications on transaction price, and the Company’s
measure of progress in fulfilling the performance obligation to which they relate, may be recognized as an adjustment to
revenue on a cumulative catch-up basis. Revenue from modifications that create new, distinct performance obligations is
recognized based on the Company’s progress in fulfilling the requirements of the new obligation.

For contracts in which the estimated cost to perform exceeds the consideration to be received, the Company accrues

for the entire estimated loss during the period in which the loss is determined by recording additional direct costs.

For performance obligations that are satisfied over time, the Company recognizes the cost to fulfill contracts as
incurred, unless the costs are within the scope of another topic in which case the guidance of that topic is applied. The
Company evaluates incremental costs of obtaining a contract and, if they are recoverable from the client and relate to a
specific future contract, they are deferred and recognized over contract performance or the estimated life of the customer
relationship if renewals are expected. The Company expenses these costs when incurred if the amortization period is one year
or less.

Unfulfilled performance obligations represent amounts expected to be earned on contracts and do not include the
value of negotiated, unexercised contract options, which are classified as marketing offers. Indefinite delivery/indefinite
quantity and similar arrangements provide a framework for the client to issue specific tasks, delivery or purchase orders in
the future and these arrangements are considered marketing offers until a specific order is executed.

Revenue recognition entails the use of significant judgment, including, but not limited to, the following: evaluating
agreements in terms of the number and nature of performance obligations; determining the appropriate method for measuring
progress to satisfaction of obligations; determining if the Company is acting as a principal or an agent, and preparing estimates
in terms of the amount of progress that the Company has made. Most of the Company’s revenue is recognized over time. For
many fixed-price contracts, in particular, the Company estimates the proportion of total revenue earned using the ratio of
contract costs incurred to total estimated contract costs, which requires the Company to prepare and, as necessary, revise
estimates, as work progresses, of the total contract costs required to satisfy each respective performance obligation. Moreover,
some of the Company’s contracts include variable consideration, which requires the Company to estimate and, as necessary,
revise the most likely amounts that will be earned over the respective performance assessment periods. For these obligations,
changes in estimates result in cumulative catch-up adjustments and may have a significant impact on earnings during a given
period.

F-9

The Company’s operating cycle for long-term contracts may be greater than one year and is measured by the average
time intervening between the inception and the completion of those contracts. Contract-related assets and liabilities are
classified as current assets and current liabilities. Significant balance sheet accounts related to the revenue recognition cycle
are as follows:

Contract receivables, net – This account includes amounts billed or billable under contract terms. The amounts due
are stated at their net realizable value. The Company maintains an allowance for doubtful accounts to provide for
the estimated amount of receivables that will not be collected. The Company considers a number of factors in its
estimate of the allowance, including knowledge of a client’s financial condition, its historical collection
experience, and other factors relevant to assessing the collectability of the receivables.

Contract assets – This account includes unbilled amounts typically resulting from revenue recognized on long-
term contracts when the amount of revenue recognized exceeds the amounts billed. It also includes contract
retainages until the Company has met the contract-stipulated requirements for payment. Contract assets are
reported in a net position on a contract by contract basis each period even though individual contracts may contain
multiple performance obligations. On a contract by contract basis, amounts do not exceed their net realizable value.

Cash and Cash Equivalents

The Company considers cash on deposit and all highly liquid investments with original maturities of three months or

less when purchased to be cash and cash equivalents.

Restricted Cash

The Company has restricted cash representing amounts held in escrow accounts and/or not readily available due to

contractual restrictions.

Allowance for Doubtful Accounts

The Company considers a number of factors in its estimate of allowance for doubtful accounts, including the client’s
financial condition, historical collection experience, and other factors that may bear on collectability of the receivables. The
Company writes off specific contract receivables when such amounts are determined to be uncollectible.

Property and Equipment

Property and equipment are carried at cost and are depreciated using the straight-line method over their estimated
useful lives, which range from two to seven years. Leasehold improvements are amortized on a straight-line basis over the
shorter of the economic life of the improvement or the related lease term.

Goodwill and Other Intangible Assets

The purchase price of an acquired business is allocated to the tangible assets and separately identifiable intangible
assets acquired, less liabilities assumed, based on their respective fair values, with the excess recorded as goodwill. Goodwill
represents the excess of costs over the fair value of net assets of businesses acquired. Goodwill and intangible assets acquired
in a business combination and determined to have an indefinite useful life are not amortized, but instead are reviewed for
impairment annually, or more frequently if impairment indicators arise. Intangible assets with estimable useful lives are
amortized over such lives and reviewed for impairment if impairment indicators arise.

Impairment

The Company performs its annual goodwill impairment test as of October 1 of each year. The Company assesses
goodwill at the reporting level. As its business is highly integrated and all of its components have similar economic
characteristics, the Company concluded it has one reporting unit at the consolidated entity level. the goodwill impairment
test as of October 1, 2018, the Company opted to perform a qualitative assessment of whether it is more likely than not that
its reporting unit's fair value is less than its carrying amount. If, after completing its qualitative assessment, the Company
determines that it is more likely than not that the estimated fair value of the reporting unit exceeded its carrying amount, it
may conclude that no impairment exists. If the Company concludes otherwise, a goodwill impairment test must be performed,
which includes a comparison of the reporting unit’s fair value to the carrying amount and recognizing, as an impairment loss,
the difference of the reporting unit’s fair value and the carrying amount of goodwill.

F-10

The Company’s qualitative analysis as of October 1, 2018 included macroeconomic, industry and market specific
considerations, financial performance indicators and measurements, and other factors. Based on this qualitative assessment,
the Company determined that it is more likely than not that the fair value of its reporting unit exceeded its carrying amount,
and thus the impairment test was not required to be performed. Therefore, based on management’s review, a goodwill
impairment loss was not required for 2018. Historically, the Company has not recorded any goodwill impairment losses.

The Company is required to review long-lived assets and certain identifiable intangibles for impairment whenever
events or changes in circumstances indicate that the carrying amount of an asset might not be recoverable. Recoverability of
assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash
flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is
measured by the amount by which the carrying amount of the asset exceeds its fair value. Assets to be disposed of are reported
at the lower of the carrying amount or fair value, less cost to sell.

Capitalized Software

The Company capitalizes certain costs to develop enhancements and upgrades to internal-use software that are
incurred subsequent to the preliminary project stage. Amortization expense is recorded on a straight-line basis over the
expected economic life of the software, typically lasting three to five years. During the years ended December 31, 2018,
2017 and 2016, the costs capitalized for the development of internal-use software were not material to the Company’s
consolidated financial statements.

Deferred Rent

The Company recognizes rent expense on a straight-line basis over the non-cancellable term of each lease, including
renewal option periods when renewal is reasonably assured or executed. Lease incentives or abatements received at or near
the inception of leases are accrued and amortized ratably over the life of the lease.

Stock-based Compensation

The Company recognizes stock-based compensation expense related to share-based payments to employees,
including grants of employee stock options, restricted stock awards, restricted stock units (“RSUs”), and cash-settled
restricted stock units (“CSRSUs”) on a straight-line basis over the requisite service period, which is generally the vesting
period. The Company recognizes expense for performance-based share awards (“PSAs”), which have both performance
requirements and vesting conditions, on a straight-line basis over the three-year performance period. Non-employee director
awards, which do not include vesting conditions, are for board-related services and therefore expensed when earned.

Stock-based compensation expense is based on the estimated fair value of the instruments on award and the estimated
number of shares the Company ultimately expects will vest. The Company estimates the rate of future forfeitures based on
factors which include the historical forfeiture experience for each applicable employee class under the assumption that the
rate of future forfeitures will be similar to that experienced in the past. In addition, the estimation of PSAs that will ultimately
vest requires judgment based on the performance and market conditions that will be achieved over the performance period.
Changes to these estimates are recorded as a cumulative adjustment in the period estimates are revised.

The fair value of stock options, restricted stock awards, RSUs, PSAs, and non-employee director awards is estimated
based on the fair value of a share of common stock at the grant date. The Company has elected to use the Black-Scholes-
Merton option pricing model to determine the fair value of stock options. The fair value of PSAs is estimated using a Monte
Carlo simulation model.

CSRSUs are settled only in cash payments. The cash payment is based on the fair value of the Company’s stock price
at the vesting date, calculated by multiplying the number of CSRSUs vested by the Company’s closing stock price on the
vesting date, subject to a maximum payment cap and a minimum payment floor. The Company treats these awards as liability-
classified awards, and, therefore, accounts for them at fair value estimated based on the closing price of the Company’s stock
at the reporting date.

Other Comprehensive Income (Loss)

Other comprehensive income (loss) represents foreign currency translation adjustments arising from the use of
differing exchange rates from period to period, the gain on the sale of an interest rate hedge agreement designated as a cash
flow hedge, and the changes in fair value of interest rate agreements designated as cash flow hedges, net of taxes. The financial
positions and results of operations of the Company’s foreign subsidiaries are based on the local currency as the functional
currency and are translated to U.S. dollars for financial reporting purposes. Assets and liabilities of the subsidiaries are
translated at the exchange rate in effect at each balance sheet date. Income statement accounts are translated at the average

F-11

rate of exchange prevailing during the period. Translation adjustments are reported in accumulated other comprehensive loss
included in stockholders’ equity in the Company’s consolidated balance sheets.

Derivative Instruments

Derivative instruments designated as cash flow hedges are recorded on the consolidated balance sheet at fair value as
of the reporting date, and the effective portion of the hedge is recorded in other comprehensive income (loss) on the
consolidated statement of comprehensive income and reclassified to earnings in the period that the hedged instruments affect
earnings. Management reviews the effectiveness of the hedges on a quarterly basis.

Income Taxes

The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of temporary
differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.
Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary
differences are expected to be recovered or settled. The Company evaluates its ability to benefit from all deferred tax assets
and establishes valuation allowances for amounts it believes will more likely than not be unrealizable. For uncertain tax
positions, the Company uses a more-likely-than-not recognition threshold based on the technical merits of the income tax
position taken. Income tax positions that meet the more-likely-than-not recognition threshold are measured in order to
determine the tax benefit recognized in the financial statements. Penalties, if probable and reasonably estimable, and interest
expense related to uncertain tax positions are not recognized as a component of income tax expense but recorded separately
in indirect expenses and interest expense, respectively.

Treasury Shares

Treasury shares are accounted for under the cost method.

Segment, Customer and Geographic Information

The Company operates in one segment based on the consolidated information used by its chief operating decision
maker in evaluating the financial performance of its business and allocating resources. This single segment represents the
Company’s core business which is providing professional services for government and commercial clients. Although, the
Company disaggregates its revenue by client market areas and type, the Company does not manage its business or allocate
resources based on client market or type.

Approximately $543.9 million, $550.3 million, and $563.0 million of the Company’s revenue for the years 2018,
2017, and 2016, respectively, was derived under prime contracts and subcontracts with agencies and departments of the
federal government representing 41%, 45%, and 48% of total revenue, respectively. No other customer accounted for 10%
or more of the Company’s revenue during the years ended 2018, 2017, and 2016, respectively.

The Company’s international operations provide services to both commercial and international government clients.
Revenue is attributed to a particular geographic area based on the administrative location of the client that awarded the
contract. The Company’s revenue generated from international clients as a percentage of total revenue was approximately
15%, 9%, and 10% for the years 2018, 2017, and 2016, respectively.

At December 31, 2018 and 2017, long-lived assets held internationally were 12.2% and 7.9% of total long-lived

assets, respectively.

Risks and Uncertainties

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash
and cash equivalents and contract receivables. The majority of the Company’s cash transactions are processed through one
U.S. commercial bank. Cash held domestically in excess of daily requirements is used to reduce any amounts outstanding
under the Company’s Credit Facility. As of December 31, 2018 and 2017, the Company held approximately $11.9 million
and $10.4 million, respectively, of cash in foreign bank accounts (not including outstanding deposits and checks). To date,
the Company has not incurred losses related to cash and cash equivalents.

The Company’s receivables consist principally of amounts due from agencies and departments of the federal
government, state and local governments, and international governments, as well as from commercial organizations. The
credit risk, with respect to federal and other government clients, is limited due to the credit-worthiness of the respective
governmental entity. Amounts due for work performed as a subcontractor to a commercial organization also represent limited
credit risk when the commercial client is performing as the prime contractor on a government contract due to the ultimate
credit-worthiness of the end client. Receivables from commercial clients generally pose a greater credit risk, and, as a result,

F-12

are subject to ongoing monitoring. The Company extends credit in the normal course of operations and does not require
collateral from its clients.

The Company has historically been, and continues to be, heavily dependent on contracts with the federal government
which are subject to audit by agencies and departments of the federal government. Such audits determine, among other things,
whether an adjustment to invoices previously rendered are required under regulations as well as the underlying terms of each
respective contract. Management does not expect significant adjustments as a result of government audits that will adversely
affect the Company’s financial position and results of operations.

Accumulated Other Comprehensive Loss

In February 2018, the Financial Accounting Standards Board (“FASB”) issued ASU 2018-02: Income Statement –
Reporting Comprehensive Income (Topic 220). In the past, certain transactions were recorded in accumulated other
comprehensive income net of applicable taxes. The tax had been calculated based on the tax rates enacted at the time the
transaction occurred with no provision, under previous accounting, for adjusting the balance for changes in the enacted tax
rate. Due to the passage of the Tax Cuts and Jobs Act of 2017 (the “Tax Act”), those historical tax rates used for recording
the transactions were higher than the Company’s current enacted rate. The new guidance allows the Company to reclassify
these stranded tax effects directly to retained earnings. This update is effective for fiscal years beginning after December 15,
2018, including interim periods therein, and early adoption is permitted. During the first quarter of 2018, the Company elected
to early adopt the update, which resulted in a one-time cumulative effect adjustment of $0.8 million from accumulated other
comprehensive loss to retained earnings.

Revenue Recognition

The Company implemented ASU 2014-09, Revenue from Contracts with Customers (Topic 606), on January 1, 2018
using the modified retrospective method. This method requires that the Company apply the requirements of the new standard
in the year of adoption to new contracts and those that were not completed as of the adoption date. Management evaluated
those contracts not completed as of the adoption date and concluded that the required cumulative adjustment to those contracts
did not have a material impact on the Company. Contract assets and contract liabilities were formerly reported as unbilled
accounts receivable and deferred revenue, respectively. The titles have been changed in the table below to be consistent with
accounts currently used under the new standard.

Unfulfilled performance obligations for contracts in process as of the adoption date were $1.1 billion.

Under the modified retrospective method, the Company is required to maintain dual reporting during the year of
adoption in order to present revenue under both the previous and new accounting for contracts initiated on or after the date
of adoption and for those contracts having remaining obligations as of the adoption date. Revenue timing differences between
the two methods resulted primarily from contracts with performance incentives. Under the new accounting, the Company has
included in revenue the most likely amount of priced incentives earned as contract work was performed rather than, as under
the old accounting, waiting to recognize revenue from incentives until specific quantitative goals were achieved, generally at
the end of the performance assessment period. This timing difference did not result in a material change to the Company’s
annual revenue since most incentives have one-year performance assessment periods which are aligned with the Company’s
fiscal year. Revenue calculated under the old and new methods is as follows:

Revenue .................................................................................................................... $

Leases

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This standard revises the accounting for leases
and requires lessees to recognize, for all leases with terms of greater than one year, a right-of-use asset and lease liability
which depicts the rights and obligations arising from a lease. The standard also requires qualitative and quantitative
disclosures designed to provide information regarding the nature, amount and timing of lease expense. The new guidance is
not expected to significantly change the recognition and measurement of lease expense. It is effective for the first interim
and annual periods beginning after December 15, 2018, with early adoption permitted. In July 2018, the FASB issued ASU
2018-11, Leases (Topic 842), Targeted Improvements permitting the recognition of a cumulative-effect adjustment to retained
earnings on the date of adoption. The Company adopted the standard beginning January 1, 2019 using the alternative
transition method. The Company is finalizing the value as of the adoption date of the right-of-use asset and lease liabilities
and estimates that the right-of-use asset will be between $140 million and $165 million and the lease liability will be between
$155 million and $180 million. The Company does not expect a material impact from adopting the new standard on the results
of operations or cash flows.

Financial Instruments

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of
Credit Losses on Financial Instruments. The standard requires that the Company present financial assets measured at
amortized costs at the net amount expected to be collected based on historical experience, current conditions, and reasonable
and supportable forecasts that affect the collectability of the assets. The standard is effective for annual reporting periods
beginning after December 15, 2019, including interim periods within that reporting period. The Company is currently in the
process of evaluating the impact of adoption, but does not anticipate a material impact on the consolidated financial statements
as a result of adopting the standard.

Stock Compensation

In June 2018, the FASB issued ASU 2018-07, Compensation—Stock Compensation (Topic 718). The standard
simplifies the accounting for share-based compensation to non-employees by aligning the guidance with share-based
payments to employees. It is effective for interim and annual reporting periods beginning after December 15, 2018 with early
adoption permitted. The Company is currently in the process of evaluating the impact of adoption, but does not anticipate a
material impact on the consolidated financial statements as a result of adopting the standard.

Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract

In August 2018, the FASB issued ASU 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic
350-40). The standard aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is
considered a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain
internal-use software. The standard also requires the entity to expense the capitalized implementation costs of a hosting
arrangement over the term of the hosting arrangement and 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 arrangement. The standard is effective
for interim periods and fiscal years beginning after December 15, 2019 with early adoption permitted. The standard may be
implemented using either the retrospective or prospective method. The Company is currently in the process of evaluating the
impact of adoption and mode of adoption but does not anticipate that there will be a material impact on the consolidated
financial statements as a result of adopting the standard.

The weighted-average period of amortization for all intangible assets as of December 31, 2018 is 8.4 years. The customer-
related intangible assets, which consist of customer contracts, backlog, and non-contractual customer relationships, are being
amortized based on estimated cash flows and respective estimated economic benefit of the assets. The weighted-average
period of amortization of the customer-related intangibles is 8.4 years. Intangible assets related to developed technology are
being amortized on an accelerated basis over a weighted-average period of 4.8 years. Intangible assets with an indefinite life

NOTE 8 - LONG-TERM DEBT

On May 17, 2017, the Company entered into a Fifth Amended and Restated Business Loan and Security Agreement
with a syndication of 11 commercial banks (the “Credit Facility”). The Credit Facility: (i) includes modifications to the
Company’s Fourth Amended and Restated Business Loan and Security Agreement, (ii) matures on May 17, 2022, (iii)
increases the borrowing ceiling up to $600.0 million without a borrowing base requirement, taking into account financial,
performance-based limitations, and (iv) provides for an “accordion,” which permits additional revolving credit commitments
of up to $300.0 million, subject to lenders’ approval. While the modification of the Credit Facility did not increase the amount
of outstanding, $106.0 million of funds from new syndicated borrowings was used to pay off or pay down borrowings from
syndicate members prior to the loan modification and align the allocation of debt within the syndicate. These amounts were
included within the “Advances from working capital facilities” and “Payments on working capital facilities” line items in the
statement of cash flows for the year ended December 31, 2017.

F-16

The Company has the option to borrow funds under the Credit Facility at interest rates based on both LIBOR (1, 3,
or 6 month rates) and the Base Rate, at its discretion, plus their applicable margins. Base Rates are fluctuating per annum
rates of interest equal to the highest of (i) the Federal Funds Open Rate, plus 0.5%, (ii) the Prime Rate, and (iii) the daily
LIBOR rate, plus a LIBOR Margin of between 1.00% and 2.00% based on our Leverage Ratio (as defined under the Credit
Facility), 1.25% as of December 31, 2018. The interest accrued based on LIBOR rates is to be paid on the last business day
of the interest period (1, 3, or 6 months), while interest accrued based on the Base Rates is to be paid in quarterly installments.
The Credit Facility provides for letters of credit aggregating up to $60.0 million which reduce the funds available under the
Credit Facility when issued. The Credit Facility is collateralized by substantially all of the assets of the Company and requires
that the Company remain in compliance with certain financial and non-financial covenants. The financial covenants require,
among other things, that the Company maintain at all times an Interest Coverage Ratio (as defined under the Credit Facility)
of not less than 3.00 to 1.00 and a Leverage Ratio of not more than 3.75 to 1.00 (subject to adjustment, in certain
circumstances) for each fiscal quarter. As of December 31, 2018, the Company was in compliance with its covenants under
the Credit Facility.

The Credit Facility was subject to a commitment fee on the unused portion of the Credit Facility of between 0.13%
and 0.25% per annum, based on our Leverage Ratio, 0.15% per annum at December 31, 2018 and 0.15% per annum at
December 31, 2017.

As of December 31, 2018, the available borrowing capacity under the Credit Facility (excluding the accordion) was
$396.3 million. Taking into account the financial and performance-based limitations, the available borrowing capacity
(excluding the accordion) was $284.3 million as of December 31, 2018.

Long-term debt outstanding and the weighted average interest rate is summarized as follows:

Debt Issuance Cost

The Company’s debt issuance costs, which are included within other assets, are amortized over the term of
indebtedness. Amortizable debt issuance costs were $6.9 million and $6.9 million as of December 31, 2018 and 2017,
respectively. Accumulated amortization related to debt issuance costs were $5.2 million and $4.7 million, as of December
31, 2018 and 2017, respectively. Amortization expense of $0.5 million, $0.7 million, and $0.5 million was recorded for each
of the years ended December 31, 2018, 2017, and 2016, respectively.

Letters of Credit

At December 31, 2018 and 2017, the Company had eleven and twelve outstanding letters of credit totaling

approximately $3.3 million and $3.7 million, respectively. These letters of credit are renewed annually.

NOTE 9 – REVENUE RECOGNITION

Disaggregation of Revenue

The Company disaggregates revenue from clients, most of which is earned over time, into categories that depict how
the nature, amount and uncertainty of revenue and cash flows are affected by economic factors. Those categories are client
market, client type and contract mix. Client market provides insight into the breadth of the Company’s expertise. In classifying
revenue by client market, the Company attributes revenue from a client to the market that the Company believes is the client’s
primary market. The Company also classifies revenue by the type of entity for which it does business, which is an indicator
of the diversity of its client base. The Company attributes revenue generated as a subcontractor to a commercial company as
government revenue when the ultimate client is a government agency or department. Disaggregation by contract mix provides
insight in terms of the degree of performance risk that the Company has assumed. Fixed-price contracts are considered to
provide the highest amount of performance risk as the Company is required to deliver a scope of work or level of effort for a
negotiated fixed price. Time-and-materials contracts require the Company to provide skilled employees on contracts for
negotiated fixed hourly rates. Since the Company is not required to deliver a scope of work, but merely skilled employees, it
considers these contracts to be less risky than a fixed-price agreement. Cost-based contracts are considered to provide the
lowest amount of performance risk since the Company is generally reimbursed for all contract costs incurred in performance
of contract deliverables with only the amount of incentive or award fees (if applicable) dependent on the achievement of
negotiated performance requirements.

Contract Balances:

Contract assets consist primarily of unbilled amounts resulting from long-term contracts when revenue recognized
exceeds the amount billed due to billing schedule timing. Contract liabilities result from advance payments received on a
contract or from billings in excess of revenue recognized on long-term contracts due to billing schedule timing. The $8.6
million increase in the Company’s net contract assets (liabilities) is due to the timing of work performed in relation to billing
schedule timing for fixed price programs which resulted in a reduction in contract liabilities, particularly in our international
operations. The increase in contract assets is primarily due to hurricane relief and rebuild work for U.S. state and local
governments which is considered part of the energy, environment and infrastructure client market, and most of which has
been performed on time-and-materials agreements. The decrease in contract liabilities is primarily due to advanced billing
for costs in 2017 that has been recognized as revenue in 2018. There were no material changes to contract balances due to
impairments or business combinations during the period.

Performance Obligations:

The Company had $1.4 billion in unfulfilled performance obligations as of December 31, 2018, which primarily
entail the future delivery of services for which revenue will be recognized over time. The obligations relate to continued or
additional services required on contracts and were generally valued using an estimated cost-plus margin approach, with
variable consideration being estimated at the most likely amount. The Company expects to satisfy these performance
obligations, on average, in one year.

NOTE 10 - DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

The Company uses interest rate swap arrangements (the “Swaps”) to manage or hedge its interest rate risk.
Notwithstanding the terms of the Swaps, the Company is ultimately obligated for all amounts due and payable under the
Credit Facility. The Company does not use such instruments for speculative or trading purposes.

On August 8, 2018, the Company entered into two floating-to-fixed interest rate Swaps for an aggregate notional
amount of $75.0 million in order to hedge a portion of the Company’s floating rate indebtedness under the Credit
Facility. The Company designated these Swaps as cash flow hedges. These Swaps requires us to pay a fixed rate of 2.8530%
per annum on the notional amount. The cash flows from these Swaps began August 31, 2018 and end on August 31, 2023.

On August 31, 2017, the Company entered into a floating-to-fixed interest rate Swap for an aggregate notional amount
of $25.0 million to hedge a portion of the Company’s floating rate indebtedness. This Swap requires us to pay a fixed rate of
1.8475% per annum on the notional amount. The cash flows from the transaction began August 31, 2018 and end on August
31, 2023. The Company has designated this hedge as a cash flow hedge.

On September 30, 2016, the Company entered into a floating-to-fixed interest rate hedge agreement for an aggregate
notional amount of $100.0 million to hedge a portion of the Company’s floating rate indebtedness. The cash flows from the
interest rate swap agreement began on January 31, 2018 and end on January 31, 2023. The Company designated this hedge
as a cash flow hedge. On December 1, 2016, the Company sold the interest rate hedge agreement. The fair value of the interest
rate hedge, as of the date of the sale, was recorded in other comprehensive income, net of tax. The gain from the sale will be
recognized into earnings when earnings are impacted by the cash flows of the previously hedged items, as interest payments
are made on the Credit Facility from January 31, 2018 to January 31, 2023.

Realized gains and losses in connection with each required interest payment will be reclassified from accumulated
other comprehensive income (loss) (“AOCI”) to interest expense during the period of the cash flows. On a quarterly basis,
management evaluates all Swaps to determine each agreement’s effectiveness or ineffectiveness and records the change in
fair value as an adjustment to other comprehensive income or loss. Management intends that the Swaps remain effective.
Realized gains and losses in connection with each required interest payment will be reclassified from AOCI to interest
expense. As of December 31, 2018, the net amount of realized gains and losses from the hedge agreements expected to be
reclassified from AOCI into earnings within the next 12 months is $0.6 million.

On December 20, 2017, the U.S. Congress passed the Tax Act, which was signed into law on December 22, 2017
and is generally effective beginning January 1, 2018. The Company was impacted in several ways as a result of the Tax Act,
including, but not limited to, provisions which include a permanent reduction in the U.S. federal corporate income tax rate
from 35% to 21%, the revaluation of deferred tax assets and liabilities required as a result of the tax rate change and the
application of a mandatory one-time “transition tax” on unremitted earnings of certain foreign subsidiaries that were
previously tax deferred.

The Company has completed its accounting for the tax effects of enactment of the Tax Act. The Company recorded
adjustments to the provisional estimate of the effects on existing deferred tax balances and the one-time transition tax in the
period of enactment. The Company recognized these adjustments to the provisional estimate as a decrease in the provision
for income taxes.

The Company re-measured certain deferred tax assets and liabilities based on the rates at which they are expected to
reverse in the future, which is now generally 26.4%. The Company has completed its analysis of the Tax Act and refining
its provisional estimates, which affected the measurement of these balances. Pursuant to U.S. Securities and Exchange
Commission Staff Accounting Bulletin 118 (“SAB 118”), the provisional amount recorded related to the re-measurement of
the deferred tax balances has been adjusted during the measurement period ended December 22, 2018 as an increase in the
provision for income taxes, including adjustments to valuation allowances, of approximately $1.0 million.

The one-time “transition tax” is based on the Company’s total post-1986 earnings and profits (“E&P”) which the
Company has previously deferred from U.S. income taxation. The Company has completed the calculation of the total post-
1986 foreign E&P and related foreign tax pools for these foreign subsidiaries. Further, the transition tax is based in part on
the amount of those earnings held in cash and other specified assets. This amount, as well as the related foreign tax credit
utilization, changed as the Company finalized its calculation of post-1986 foreign E&P and related foreign tax pools that
were previously deferred from U.S. federal taxation and the amounts held in cash or other specified assets. Similarly, the
cumulative foreign tax credit carry forward balance as of December 31, 2017 increased by approximately $2.2 million and
the valuation allowance required increased by approximately $2.2 million. No additional income taxes have been provided
for on any remaining undistributed foreign earnings not subject to the transition tax. No additional deferred income taxes
have been provided for the $8.2 million of additional favorable outside basis differences inherent in these foreign entities
because these amounts continue to be permanently reinvested in foreign operations. Pursuant to SAB 118, the provisional
amount recorded related to the transition tax has been adjusted during the measurement period ended December 22,
2018. The Company recognized this adjustment to the provisional estimate as a decrease in the provision for income taxes
of approximately $1.1 million during the third quarter of 2018.

At both December 31, 2018 and 2017, the Company had net operating loss (“NOL”) carry-forwards for foreign
income taxes of approximately $3.5 million and $4.1 million, respectively, all of which may be carried forward indefinitely.

At December 31, 2018, the Company had NOL carry-forwards for state income tax purposes of approximately $8.9
million, which expire in 2034. The Company acquired these NOLs as a result of its purchase of Olson in November 2014.
Internal Revenue Code Section 382 imposes an annual limitation on the use of a corporation’s NOLs, tax credits and other
carryovers after an “ownership change” occurs. Section 382 imposes an annual limitation on the amount of post-ownership
change taxable income a corporation may offset with pre-ownership change NOLs and credits. In general, the annual
limitation is determined by multiplying the value of the corporation’s stock immediately before the ownership change (subject
to certain adjustments) by the applicable long-term tax-exempt rate. Any unused portion of the annual limitation is available
for use in future years until such NOLs are scheduled to expire (in general, NOLs may be carried forward 20 years). The
Company presently estimates that it will be able to fully utilize the remaining acquired NOLs prior to their expiration.

At December 31, 2018, the Company had gross state income tax credit carry-forwards of approximately $2.6 million,
which expire between 2021 and 2027. A deferred tax asset of approximately $2.0 million (net of federal benefit) has been
established related to these state income tax credit carry-forwards as of December 31, 2018.

The need to establish valuation allowances for deferred assets is based on a more-likely-than-not threshold that the
benefit of such assets will be realized in future periods. Appropriate consideration has been given to all available evidence,
including historical operating results, projections of taxable income, and tax planning alternatives. The Company concluded
that a valuation allowance of approximately $1.1 million and $1.1 million was required for tax attributes related to specified
foreign jurisdictions as of December 31, 2018 and 2017, respectively, and an additional $3.5 million valuation allowance was
recorded against our US foreign tax credit carry forwards as a result of enactment of the Tax Act as of December 31, 2017.

The total amount of unrecognized tax benefits as of December 31, 2018 and 2017, was $0.2 million and $0.8 million,
respectively. Included in the balance as of December 31, 2018 and 2017, were $0.2 million and $0.7 million, respectively, of
tax positions that, if recognized, would impact the effective tax rate.

F-21

The unrecognized tax benefit reconciliation, excluding penalty and interest, is as follows:

Unrecognized tax benefits at January 1, 2016 .............................................................................. $
Increase attributable to tax positions taken during a prior period ..............................................
Decrease attributable to lapse of statute of limitations ..............................................................

The Company’s policy is not to recognize accrued interest and penalties related to unrecognized tax benefits as a
component of tax expense. The Company had approximately zero and $0.2 million of accrued penalty and interest at
December 31, 2018 and 2017, respectively.

The Company’s 2014 to 2017 tax years remain subject to examination by the Internal Revenue Service for federal
tax purposes. Certain significant state and foreign tax jurisdictions are also either currently under examination or remain open
under the statutes of limitation and subject to examination for the tax years from 2014 to 2017.

Although the Company believes it has adequately provided for all uncertain tax positions, amounts asserted by taxing
authorities could be greater than the Company’s accrued position. Accordingly, additional provisions on federal, state and
foreign income tax related matters could be recorded in the future as revised estimates are made or the underlying matters are
effectively settled or otherwise resolved. Conversely, the Company could settle positions with the tax authorities for amounts
lower than have been accrued. The Company believes it is reasonably possible that, during the next 12 months, the Company’s
liability for uncertain tax positions may not change.

The Company’s provision for income taxes differs from the federal statutory rate. The differences between the

statutory rate and the Company’s provision are as follows:

December 1, 2016. The fair value of the interest rate hedge agreement was recorded in other comprehensive income,
net of tax, and will be reclassified to earnings when earnings are impacted by the hedged items, as interest payments
are made on the Credit Facility from January 31, 2018 to January 31, 2023.

NOTE 14 - ACCOUNTING FOR STOCK-BASED COMPENSATION

Stock Incentive Plans

On April 4, 2018, the Company’s board of directors approved the 2018 Omnibus Incentive Plan (the “2018 Omnibus
Plan”), which was subsequently approved by the stockholders and became effective on May 31, 2018 (the “Effective
Date”). The 2018 Omnibus Plan replaced the previous 2010 Omnibus Incentive Plan (the “Prior Plan”).

On or after the Effective Date, the 2018 Omnibus Plan allows the Company to grant 1,185,000 shares using stock
options, stock appreciation rights, restricted stock, RSUs, performance units and PSAs, cash-based awards, and other stock-
based awards to all key officers, key employees, and non-employee directors of the Company. Outstanding grants under the
Prior Plan, totaling 568,801, remain subject to their terms and conditions, and no additional awards from the Prior Plan are
to be made after the Effective Date. As of December 31, 2018, the Company had approximately 1,098,906 shares available
to grant under the 2018 Omnibus Plan. CSRSUs have no impact on the shares available for grant under the 2018 Omnibus
Plan and have no impact on the calculated shares used in earnings per share calculations.

The total stock-based compensation expense for the years ended December 31, 2018, 2017, and 2016, the
unrecognized compensation expense at December 31, 2018, and the weighted-average period to recognize the remaining
unrecognized shares are as follows:

The assumptions of employment termination forfeiture rates used in the determination of fair value of stock awards
during the 2018 calendar year were based on the Company’s historical average of actual forfeitures from the previous 5 years
preceding the reporting period. The expected annualized forfeiture rates used during the 2018 calendar year varied from 0%
to 18.17%, and the Company does not expect these termination rates to vary significantly in the future.

Stock Options

Option awards are granted with an exercise price equal to the market value of the Company’s common stock on the
date of grant. All options outstanding as of December 31, 2018 have a 10-year contractual term. Options generally have a
vesting term of three or four years. There were no option awards granted during 2018, 2017, and 2016.

Non-Employee Director Awards

In the first six months of 2018, the Company granted awards of unregistered shares to its non-employee directors on
a quarterly basis under its Annual Equity Election. The awards were issued from the Company’s treasury stock and had no
impact on the shares available for grant under the 2018 Omnibus Plan or the Prior Plan. The awards do not include vesting
conditions; thus, there was no unrecognized expense related to these awards at December 31, 2018.

Performance Share Awards

In the first quarter of 2015, the Company’s Board of Directors approved a performance-based share program (the
“Program”) that provides for the issuance of PSAs to its senior management. Under the Program, the number of PSAs that
the participant will receive depends on the Company’s achievement of two performance goals during two performance
periods. The performance goals under the Program are based on (i) the Company’s compounded annual growth rate in
earnings per share (“EPS”) during a two-year performance period and (ii) the Company’s cumulative total shareholder return
(“rTSR”) relative to its peer group during a performance period from the first day of the performance period (typically January
1 of the year awarded) to the last day of the third year of the performance period (typically December 31). The PSAs will
only be eligible to vest following the expiration of the three-year performance period. Actual shares vested will be subject to
both continued employment by the Company (barring certain exceptions allowing for partial performance periods) and actual
financial measures achieved. The actual number of shares of common stock that will be issued to each participant at the end
of the applicable performance period will be determined by multiplying the award by the product of two percentages, one
based on the Company’s EPS performance and a second one based on the Company’s rTSR performance, subject to a
minimum and maximum performance level. As of December 31, 2018, shares granted during 2016, 2017, and 2018 are within
year three, two, and one of the performance period, respectively, and therefore have not vested. A total of 30,576 shares
granted in 2015 vested during 2018 after meeting the performance goals.

The aggregate intrinsic value in the preceding table is based on the Company’s closing stock price of $64.78 per share
as of December 31, 2018. The fair value of the awards is estimated on the grant date using a Monte Carlo simulation model
due to the market condition for the rTSR component. The fair value assumptions using the Monte Carlo simulation model for
awards granted in 2018, 2017, and 2016 were 0.9%, 0.0% and 0.0% for dividend yields, respectively; 31.9%, 31.3% and
30.9% for historical volatility, respectively; and 2.4%, 1.5%, and 1.0% both risk-free rate of returns, respectively.

NOTE 15 – BUSINESS COMBINATIONS

In January 2018, the Company acquired TFC, a leading boutique loyalty strategy and marketing company based in
London, United Kingdom. The acquisition of TFC enhanced and extended the Company’s customer loyalty business to
Europe.

In August 2018, the Company acquired DMS Disaster Consultants (“DMS”), a disaster management and recovery
firm based in Florida. DMS assists public sector clients with man-made and natural disaster planning and preparedness, and
post-disaster response and recovery efforts by assisting clients in obtaining funding from Federal Emergency Management
Agency, insurance companies, and other sources.

In October 2018, the Company acquired We Are Vista (“Vista”), a communication company headquartered in Leeds,
U.K., with an additional presence in London. Vista provides advisory services and solutions to clients in the financial, retail,
automobile, and energy industries.

The combined purchase consideration for these acquisitions totaled $51.2 million, which included $34.6 million of
initial cash payments, net of cash acquired. The Company recognized the fair value of the assets acquired and liabilities
assumed and allocated $32.1 million to goodwill, $10.6 million to intangible assets consisting primarily of customer
relationships that will be amortize on an accelerated basis based on projected customer payments and $1.2 million in
contingent consideration to be paid to a former owner if certain objectives are achieved (Level 3 fair value.). As of December
31, 2018, the Company has recorded $6.5 million of extended purchase commitments under the acquisition agreements. The
Company determined the fair value of the contingent liability as of the acquisition date using a valuation model which
included the most likely outcome and the application of an appropriate discount rate. At December 31, 2018, the Company
remeasured the contingent liability and, as a result of the remeasurement, recorded $0.5 million charge. As part of one of the
acquisitions, the purchase agreement includes additional consideration in the form of two warranty and indemnity hold back
payments, one for approximately $2.0 million scheduled to be released in 18 months following the close date and the other
for $1.2 million scheduled to be released four years from the close date. The two warranty and indemnity liabilities were
recorded at their fair value discounting the liabilities at 3.0% and 3.25%, respectively.

Separately or in the aggregate, the acquisitions were not significant to the Company’s financial statements taken as a

whole.

NOTE 16 - EARNINGS PER SHARE

EPS is computed by dividing reported net income by the weighted-average number of shares outstanding. Diluted
EPS considers the potential dilution that could occur if common stock equivalents of stock options, RSUs, and PSAs were
exercised or converted into stock. PSAs are included in the computation of diluted shares only to the extent that the underlying
performance conditions (i) are satisfied as of the end of the reporting period or (ii) would be considered satisfied if the end
of the reporting period were the end of the related performance period and the result would be dilutive under the treasury
stock method. For the years ended December 31, 2018, 2017, and 2016, there were 20,291 weighted-average shares, 142
weighted-average shares, and 163,564 weighted-average shares excluded from the calculation of EPS because they were anti-
dilutive, respectively.

The dilutive effect of stock options, RSUs, and performance shares for each period reported is summarized below:

NOTE 17 - SHARE REPURCHASE PROGRAM

In the third quarter of 2015, the Company’s board of directors approved a share repurchase plan that allowed for
share repurchases through November 2017 and authorized share repurchases in the aggregate up to $75.0 million, not to
exceed limits under the Credit Facility. As part of the Company’s modification of the Credit Facility, the prior Credit Facility
limits on share repurchases were eliminated to permit unlimited share repurchases, provided the Company’s Leverage Ratio,
prior to and after giving effect to such repurchases, is not greater than 3.25 to 1.00. During September 2017, the board of
directors approved a new repurchase program and repurchase plan effective November 4, 2017 through November 4, 2019
with a limit of $100.0 million. The limitation under the Credit Facility remains unchanged.

Purchases under this program may be made from time to time at prevailing market prices in open market purchases
or in privately negotiated transactions pursuant to Rules 10b5-1 and 10b-18 under the Exchange Act and in accordance with
applicable insider trading and other securities laws and regulations. The purchases are funded from existing cash balances
and/or borrowings, and the repurchased shares are held in treasury and used for general corporate purposes. The timing and
extent to which the Company repurchases its shares will depend on market conditions and other corporate considerations at
the Company’s sole discretion.

During the year ended December 31, 2018, the Company repurchased 214,137 shares at a total cost of $13.9 million
under this program. As of December 31, 2018, approximately $86.1 million remained available under the share repurchase
plan.

NOTE 18 - FAIR VALUE

The Company measures and reports certain financial assets and liabilities at fair value in accordance with ASC 820,
Fair Value Measurements and Disclosures (“ASC 820”). Fair value is defined as the price that would be received to sell an
asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. Generally,
fair value is based on observable quoted market prices or derived from observable market data when such market prices or
data are available. ASC 820 establishes a three-level hierarchy used to estimate fair value by which each level is categorized
based on the priority of the inputs used to measure fair value:

•

Level 1: Quoted prices that are available in active markets for identical assets or liabilities;

Level 2: Quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar
assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset
or liability (e.g. interest rates and yield curves that are observable at commonly quoted intervals, and implied
volatilities); and inputs derived principally from or corroborated by observable market data by correlation or
other means; and

Level 3: Uses inputs that are unobservable and require the Company to make certain assumptions and require
significant estimation and judgment from management to use in pricing the fair value of the assets and liabilities.

As of December 31, 2018, the Company had a $1.7 million contingent liability related to an acquisition which was
measured at Level 3 (See Note 15 – Business Combinations). As of December 31, 2017, there were no assets or liabilities
measured at Level 3 on a recurring basis.

F-29

Certain financial instruments, including cash and cash equivalents, contract receivables, and accounts payable are
carried at cost, which, due to their short maturities, approximates their fair values at December 31, 2018 and 2017. The
carrying value of other long-term liabilities related to capital expenditure obligations approximates their fair value at
December 31, 2018 and 2017 based on the current rates offered to the Company for similar instruments with comparable
maturities (Level 2). The Company believes the carrying value of its Credit Facility at December 31, 2018 and 2017
approximates the estimated fair value for debt with similar terms, interest rates, and remaining maturities currently available
to companies with similar credit ratings (Level 2). The Company applies the provisions of ASC 820 to its assets and liabilities
that are required to be measured at fair value pursuant to other accounting standards, including assets and liabilities resulting
from the Company’s nonqualified deferred compensation plan, interest rate swap agreement (see Note 10 – Derivative
Instruments and Hedging Activities), and foreign currency forward contract agreements not eligible for hedge accounting.
The impact of the amounts recorded for the nonqualified deferred compensation plan, interest rate swap agreement, and the
forward contract agreements was immaterial to the consolidated financial statements.

NOTE 19 - COMMITMENTS AND CONTINGENCIES

Litigation and Claims

The Company is involved in various legal matters and proceedings arising in the ordinary course of business. While
these matters and proceedings cause it to incur costs, including, but not limited to, attorneys’ fees, the Company currently
believes that any ultimate liability arising out of these matters and proceedings will not have a material adverse effect on the
Company’s financial position, results of operations, or cash flows.

Road Home Contract

On June 10, 2016, the Office of Community Development (the “OCD”) of the State of Louisiana filed a written
administrative demand with the Louisiana Commissioner of Administration against ICF Emergency Management Services,
L.L.C. (“ICF Emergency”), a subsidiary of the Company, in connection with ICF Emergency’s administration of the Road
Home Program (the “Program”). The Program contract was a three-year, $912 million contract awarded to the Company in
2006 and that ended, as scheduled, in 2009.

The Program was primarily intended to help homeowners and landlords of small rental properties affected by
Hurricanes Rita and Katrina. In its administrative demand, the OCD sought approximately $200.8 million in alleged
overpayments to Program grant recipients. The State separately supplemented the amount of recovery it is seeking to total
approximately $220.2 million. The State of Louisiana, through the Division of Administration, also filed suit in Louisiana
state court on June 10, 2016 broadly alleging, and seeking recoupment for, the same claim made in the administrative
proceeding submission before the Louisiana Commissioner of Administration. On September 21, 2016, the Commissioner of
the Division of Administration notified OCD and the Company of his decision to defer jurisdiction of the administrative
demand filed by the OCD. In so doing, the Commissioner declined to reach a decision on the merits, stated that his deferral
would not be deemed to grant or deny any portion of the OCD’s claim, and authorized the parties to proceed on the matter in
the previously filed judicial proceeding. The Company continues to believe that this claim has no merit, intends to vigorously
defend its position, and has therefore not recorded a liability as of December 31, 2018.

Operating Leases

On March 8, 2010, the Company entered into a new lease that replaced its prior headquarters lease, which was due
to expire in October 2012. The new lease was initially for approximately 258,000 square feet, with approximately 72,000
square feet of additional space subsequently added. The lease commenced on April 1, 2010 and will expire on December 31,
2022. Base rent under the agreement is approximately $0.9 million per month with annual escalations fixed at 2.5% per year,
yielding a total lease commitment of approximately $150.6 million over the twelve-year term of the lease.

The Company has entered into various other operating leases for office space and equipment. Certain facility leases
may contain fixed escalation clauses, certain facility leases require the Company to pay operating expenses in addition to
base rental amounts, and nine leases require the Company to maintain letters of credit. Future minimum rental payments
under all non-cancelable operating leases are as follows:

NOTE 20 - EMPLOYEE BENEFIT PLANS

Retirement Savings Plan

Effective June 30, 1999, the Company established the ICF Consulting Group Retirement Savings Plan (the
“Retirement Savings Plan”). The Retirement Savings Plan is a defined contribution profit sharing plan with a cash or deferred
arrangement under Section 401(k) of the Internal Revenue Code. Participants in the Retirement Savings Plan are able to elect
to defer up to 70% of their compensation, subject to statutory limitations, and are entitled to receive 100% employer matching
contributions for the first 3% and 50% for the next 2% of their compensation. Contribution expense related to the Retirement
Savings Plan for the years ended December 31, 2018, 2017, and 2016, was approximately $16.2 million, $15.1 million, and
$14.9 million, respectively.

Deferred Compensation Plan

Certain key employees of the Company are eligible to defer a specified percentage of their cash compensation by
having it contributed to a nonqualified deferred compensation plan. Eligible employees may elect to defer up to 80% of their
base salary and up to 100% of performance bonuses, reduced by any amounts withheld for the payment of taxes or other
deductions required by law. Participants are at all times 100% vested in their account balances. The Company funds its
deferred compensation liabilities by making cash contributions to a Rabbi Trust at the time the salary or bonus being deferred
would otherwise be payable to the employee. The liability to plan participants is materially funded at all times and the plan
does not have a material net impact on the Company’s results of operations.

Employee Stock Purchase Plan

The Company has a 2006 Employee Stock Purchase Plan (“ESPP”) under which one million shares have been
authorized for issuance. The ESPP allows eligible employees to purchase shares of our common stock through payroll
deductions up to $25,000 per calendar year over six-month offering periods at a discount not to exceed 5% of the market
value on the date of each purchase period. For the year ended December 31, 2018, 22,320 shares were purchased by
employees, at an average purchase price of $63.92, and 702,506 shares remain available for future issuance. The Company
does not recognize compensation expense related to the ESPP.

NOTE 21 - SUBSEQUENT EVENTS

On February 26, 2019, the Company’s board of directors approved a $0.14 per share cash dividend. The dividend

will be paid on April 16, 2019 to shareholders of record as of the close of business on March 29, 2019.
