In addition, we were recognized for our ethics and IT leadership, as well as our employee-friendly practices. I am proud of our employees’ performance and the way they represent Parsons. We ended 2020 with revenue within 1% of guidance; net income of nearly $100 million; and records for adjusted EBITDA, adjusted (cid:40)(cid:37)(cid:44)(cid:55)(cid:39)(cid:36)(cid:3)(cid:80)(cid:68)(cid:85)(cid:74)(cid:76)(cid:81)(cid:15)(cid:3)(cid:68)(cid:81)(cid:71)(cid:3)(cid:70)(cid:68)(cid:86)(cid:75)(cid:3)(cid:193)(cid:82)(cid:90)(cid:3)(cid:11)(cid:86)(cid:72)(cid:72)(cid:3) “Company Performance Highlights” (cid:73)(cid:82)(cid:85)(cid:3)(cid:68)(cid:3)(cid:71)(cid:72)(cid:192)(cid:81)(cid:76)(cid:87)(cid:76)(cid:82)(cid:81)(cid:3)(cid:82)(cid:73)(cid:3)(cid:68)(cid:71)(cid:77)(cid:88)(cid:86)(cid:87)(cid:72)(cid:71)(cid:3)(cid:40)(cid:37)(cid:44)(cid:55)(cid:39)(cid:36)(cid:12)(cid:17)(cid:3) We delivered net income margin of 2.5% and expanded adjusted EBITDA margins by 180 basis points over the past two years.

Our Market Opportunities Technology revolution and environmental impact is driving a swift pace of change, resulting in ongoing societal transformation, complicated geopolitical dynamics, a shifting threat landscape and the globalization of commerce. To address this evolving landscape, our customers are actively seeking technology-enabled solutions at the speed of relevancy to upgrade and transform assets and operations. The below trends are key drivers of activity and growth in both our Federal Solutions and Critical Infrastructure segments. Defense Spending Remains a Key Focus of the national agenda due to the reemergence of long-term strategic peer competition, which has been cited in the National Defense Strategy as the primary concern for U.S. national prosperity and security. This reemergence has resulted in increased global disorder and a security environment, defined by rapid technological change, which may be more complex than ever before. We believe the U.S. Department of Defense and intelligence community will continue to invest in space, C5ISR, and missile defense. 5 Cybersecurity is Mission Critical to U.S. National Security and cybersecurity threats are increasing in volume and sophistication as global connectivity and the rise of social media have led to an explosion in the amount of available and exploitable data. The recent SolarWinds hacking incident is a noteworthy example. The Center for Strategic and International Studies estimates that threats from hacks, cyber criminals, foreign governments, malicious insiders and corporate espionage have a $600 billion annual global cost impact. The proliferation of mobile devices, smart devices and cloud computing has vastly increased the need for enterprise- wide risk-based cybersecurity programs and governments have become increasingly aware of the need for a proactive approach to the risk of cyber-attacks. We believe that this market will continue to grow in response to the shifting threat landscape and recent high-profile attacks, including SolarWinds. Consistent Need for Actionable Intelligence to Support U.S. Priorities is driving a shifting threat landscape that necessitates a greater need for collaboration and cooperation between intelligence agencies. There is a new demand for joint all-domain command and control systems that are optimized to function cohesively across a spectrum of domains. This in turn drives a need for sophisticated data analytics to aggregate data into useful formats in real-time. To respond, we believe the United States intelligence community and Department of Defense will need continued focus on information sharing and collaboration for improved intelligence accuracy and timeliness encompassing multiple forms of intelligence collection. Global Infrastructure Needs Significant Replacements and Technology-Driven Upgrades. Aging physical infrastructure is strained by the swift pace of technological change combined with heightened new expectations for sustainability and environmental impact. Furthermore, failure to maintain the infrastructure makes it more difficult to recover from unexpected disasters caused by climate change. The United States infrastructure needs exceed $2 trillion according to the American Society of Civil Engineers, for roads, highways, bridges, water/ wastewater and other infrastructure needs. Critical infrastructure, specifically transportation infrastructure that is essential to national economic and security concerns including airports, bridges, and rail and transit systems, is particularly vulnerable. We believe aging infrastructure and a focus on environmental impact will continue to be replaced and supplanted by newer, smarter and more sustainable infrastructure with an increased focus on connectivity. Urbanization Creates Demand for Smart Cities with Connected Populations. Cities around the globe increasingly demand new more sustainable capabilities, such as sensor networks and communication strategies to connect streetlights, security cameras and emergency systems, to provide important real-time information and better serve their citizens and reduce carbon emissions. Integrated corridor management solutions, intelligent transportation systems, advanced rail systems and updated telecommunication networks will keep cities around the world functioning as smart and sustainable cities and serve as engines for economic growth. Transformation of Legacy Service Delivery Models through Technology. Historical capital project management is changing with the introduction of cloud-connected computer-aided design, automation, big data, machine learning and other technologies. The introduction of these new technologies allows industry participants to reimagine existing value chains, address integrated lifecycle objectives, assure human rights are observed in their supply chains, provide environmentally sensitive and sustainable solutions, boost productivity and streamline project management. Industry participants that have the capability to embrace these new technologies to enhance their capability and service offering to higher value solutions will be well positioned to assist governments and communities in their transformation. Change equals opportunity, and Parsons is well-positioned to serve a large array of governments and companies. Across a diverse set of industries, we provide smart and agile solutions that address our customers’ concerns as they adapt to the rapid changes of a more interconnected and technology-driven world. 6 Our Competitive Strengths Proven Track Record Our proven track record is a result of our strong performance, the dedication of our employees and our longstanding customer relationships.

We maintain a robust acquisition pipeline and are continually evaluating potential opportunities for disciplined growth by acquisition to further transform our business. Our Strategy for Growth Our growth strategy is focused on three pillars: Enhance, Extend and Transform. These include continually enhancing and optimizing our core business processes, extending our core business into high-growth and opportunity-rich adjacent markets and acquiring and integrating companies that possess transformative and disruptive technologies. Enhance and Optimize our Core Operations We are committed to enhancing and optimizing our core business and improving financial performance, including revenue growth, margin expansion and positive cash flow, using the following strategies: • Maintaining high re-compete rates. • Focusing on cross selling new solutions to our existing customers and existing solutions to new customers. • Continuing research and development investments in cybersecurity, intelligence and C5ISR software and hardware products, intelligent transportation systems, modeling and simulation, data analytics, advanced sensing and our as-a-service offerings. 9 • Developing intellectual property and product offerings from our investments. • • Streamlining operations and processes to optimize overhead expenditures. Increasing our presence and prime contractor positions on large omnibus Indefinite Delivery/Indefinite Quantity (“IDIQ”), Master Service Agreement and Other Transaction Agreement contracts. • Expanding our diverse talent pool in key strategic areas outside of high-employment zones. • Continuously evaluating and shaping our portfolio to divest, exit and de-emphasize lower-performing businesses and markets. • Rigorously managing our working capital to maximize cash flow. • Streamlining our processes starting with a clean baseline to optimize support function execution. Extend into Opportunity-Rich Adjacent Markets We are extending our core markets through organically penetrating and expanding in market adjacencies in need of our offerings. The characteristics of these markets encompass development, design and delivery of solutions leveraging technology, such as artificial intelligence, machine learning, cloud computing, data processing and analytics, and advanced sensing. We are expanding our core competencies to new customers and setting the pace for technological evolution in each market, including: • Cybersecurity – Continue our growth momentum in cybersecurity by offering end-to-end solutions, tools, operations and platforms for our U.S. Department of Defense and Intelligence Community customers. • • • • Space — Extend our space situational awareness, small satellite integration and payload, command and control and enterprise ground systems to our current space customers (MDA, Air Force, Space Force, Space & Missile Command, NASA and NRO) and to new space and geospatial customers in the government and commercial space markets. Integrated solutions — Help our customers reinvent the future of national security and critical infrastructure by focusing on their emerging needs. Joint all-domain operations-Leverage our command and control and sensor solutions developed for the military services into a joint command network to enable joint warfighting capability. Smart Mobility — Mobilize teams for growth, drive transactional revenue, and enhance Parsons’ marketplace positioning. Priorities include ITS/iNET™, Intelligent Intersections/AAS, Tolling/ Congestion Pricing/Vehicle Miles Traveled, and Port Freight Trucking/Freight Intelligent transportation solutions. • Life sciences and bio-surveillance — Enhance our efforts in infectious disease and health screening/ testing to the development of effective surveillance, prevention and operational capabilities for detecting and countering biological threats. • • Supply chain security – Scale our microelectronics and hardware security capabilities to position ourselves and capitalize on the emerging supply chain security market. Intelligence, surveillance, and reconnaissance integration – Move up the value chain from being a single solution provider to a large-scale integrator of C5ISR systems. • Contingency mitigation – Climate change is creating an increase in wildfires and severe storms which are problematic for the electric utility industry. We are leveraging capabilities from across our markets to manage the impact of climate change. This strategy extends the reach of our people, customer relationships and intellectual property to capture growing demand in the market adjacencies. In assessing potential areas of expansion or entry into adjacent markets, we maintain a strictly disciplined approach, always placing paramount importance on responsible growth in areas aligned with our strategy and core competencies. 10 Continued Acquisition and Integration of Transformative Technologies We are transforming our business capabilities and business models through the acquisition of companies that align with our disciplined M&A framework. Our M&A strategy and goals include: • Financial performance goals: >10% top line growth, >10% Adjusted EBITDA margin, and strong cash flow • Growing, enduring profitable markets: Cyber; Intelligence, Surveillance, and Reconnaissance; Space; Life Sciences; Smart Transportation; and Green, Sustainable markets. • High purpose mission customers: Federal civilian, intelligence community, U.S. Department of Defense, Transit Operations centers, and state Departments of Transportation. • Technology differentiation: fill technology gaps, drive end-to-end solutions, move up the value chain, scale within and across our businesses, dual use applicability, and intellectual property. Our objective is to continue to transform our business into an integrated, full life cycle systems integrator that delivers scalable solutions and drives revenue growth, expanded margins, and strong cash flows. Backlog We view growth in total backlog as a key measure of our business growth. We define backlog to include the following two components: • Funded—Funded backlog represents the revenue value of orders for services under existing contracts for which funding is appropriated or otherwise authorized less revenue previously recognized on these contracts. • Unfunded—Unfunded backlog represents the revenue value of orders for services under existing contracts for which funding has not been appropriated or otherwise authorized less revenue previously recognized on these contracts. Backlog includes (i) unissued task orders and unexercised option years, to the extent their issuance or exercise is probable, as well as (ii) contract awards, to the extent we believe contract execution and funding is probable. Our backlog includes orders under contracts that can extend for several years, and in some cases, contracts that extend for more than 10 to 15 years. For example, the U.S. Congress generally appropriates funds for our U.S. federal government customers on a yearly basis, even though their contracts with us may call for performance that is expected to take a number of years to complete. As a result, our federal contracts typically are only partially funded at any point during their term. All or some of the work to be performed under the contracts may remain unfunded unless and until the U.S. Congress makes subsequent appropriations and the procuring agency allocates funding to the contract. As of December 31, 2020, our total backlog was $8.1 billion, consisting of $4.0 billion of funded backlog and $4.1 billion of unfunded backlog. We expect to recognize $2.8 billion of our funded backlog at December 31, 2020 as revenues in the following twelve months. However, our government customers may cancel their contracts with us at any time through a termination for convenience or may elect to not exercise option periods under such contracts. In the case of a termination for convenience, we would not receive anticipated future revenues, but would generally be permitted to recover all or a portion of our incurred costs and fees for work performed. Competition The industries we operate in consist of a large number of enterprises ranging from small, niche-oriented companies to multi-billion-dollar corporations that serve many government and commercial customers. We 11 compete on the basis of our technical expertise, technological innovation, our ability to deliver cost-effective multi-faceted services in a timely manner, our reputation and relationships with our customers, qualified and/or security-clearance personnel, and pricing. Our main competitors in Federal Solutions are U.S. federal systems integrators and service providers such as Booz Allen Hamilton, CACI International Inc, Leidos Holdings, Inc., Man Tech International Corporation, Science Applications International Corporation, Lockheed Martin Corporation, Northrop Grumman Corporation, Perspecta, and The Raytheon Company. Our main competitors in Critical Infrastructure include AECOM Technology Corporation, Jacobs Engineering Group Inc., Stantec, Tetra Tech, Inc., and WSP, as well as Kapsch and Opus in the Connected Communities market. Large defense firms or technology companies may develop products or services in the future that could compete with us. Seasonality Our results may be affected by variances as a result of weather conditions and contract award seasonality impacts that we experience across our businesses. The latter issue is typically driven by the U.S. federal government fiscal year-end, September 30. While not certain, it is not uncommon for U.S. government agencies to award task orders or complete other contract actions in the weeks before the end of the U.S. federal government fiscal year in order to avoid the loss of unexpended U.S. federal government fiscal year funds. In addition, we have also historically experienced higher bid and proposal costs in the months leading up to the U.S. federal government fiscal year-end as we pursue new contract opportunities expected to be awarded early in the following U.S. federal government fiscal year as a result of funding appropriated for that U.S. federal government fiscal year. Furthermore, many U.S. state governments with fiscal years ending on June 30 tend to accelerate spending during their first quarter, when new funding becomes available. We may continue to experience this seasonality in future periods, and our results of operations may be affected by it. Human Capital Management We are committed to enhancing our position as a leading employer in our industry. Our culture and reputation as a leading provider of technology-driven solutions in the defense, intelligence and critical infrastructure markets enables us to recruit and retain some of the best available talent across the globe. We believe that we are stronger and smarter when we work together and celebrate our diverse backgrounds. We believe in doing right by the communities we serve, and we have policies prohibiting child labor and human trafficking. We believe that Parsons is the place for our diverse employees to make a difference. With over 15,500 employees, we experienced a 1.1% decrease in voluntary turnover in 2020 while converting nearly 90% of our workforce to a virtual environment during the current global COVID-19 pandemic. This improvement was largely attributed to targeted retention strategies, including a comprehensive employee development and technical career track framework and the prioritization of an ideal culture to support the transformational strategy. A high-level engagement among employees is reflected in our 2020 culture and engagement scores, which had an increased participation level of over 20%, and reflected significant improvements gained in survey areas such as alignment with strategic direction, employee connection to Parsons’ success, promotion of culture of speed and agility, rewards for coming up with new ideas, and collaboration across organization boundaries to achieve company goals. Our principal asset is our team of diverse employees. A large percentage of our employees have technical and professional backgrounds and undergraduate and/or advanced degrees, with our employees holding more than 20,000 degrees and professional credentials, including registrations and certifications in technical areas such as Agile Methodology, Project Management, Engineering, Architecture, Green Building/Sustainability, Technology, and Security as of December 31, 2020. Approximately 22% of our employees, including 58% of the employees in our Federal Solutions business segment, hold security clearances as of that date. Of those holding such clearances in Federal Solutions, approximately 58% are Top Secret/Sensitive Compartmented Information Level clearances, which often require the completion of a polygraph. 12 In 2020, we focused on retaining and developing our employees on highly sought-after key programs as part of the knitting of our success. Such programs include the mentoring program, Parsons Distinguished Recognition and Incentive Program (DRIVE), and the Parsons’ Fellows Program. Mentoring: The Parsons mentoring program allows employees to cultivate skills, seek guidance and share professional experiences. The program launched in 2020 is designed to: • • Increase a sense of connection, engagement and retention of key diverse talent. Sustain promotion and retention rates of diverse leadership talent. • Expand networks and enhance career development opportunities. Recognition: Understanding recognition at all levels is key to management and retention. We expanded Parsons Distinguished Recognition and Incentive (DRIVE) Program that celebrates employees who go above and beyond their work. Launched in 2019, with seven different award levels, the program is designed to reward employees who have made exceptional contributions to a program or project, or who have provided outstanding support to their teams, our clients, or our company as a whole. Over 1,500 awards were issued to employees in 2020 and the program is growing. Development: The Parsons’ Fellows Program recognizes our top technical experts and promotes innovation in solving our customers’ most difficult technical challenges. It is a collaborative network of over forty selected motivated and passionate subject matter experts working to solve technical challenges through either strategic research and development or through the development of long-term technical policies and best practices. The program defines its success through engagement, mentorship, and retention. Every benefit that collaboration among the Fellows offers is expressed by the idea that the individual is brilliant, but a group of brilliant individuals acting as one can be more powerful and enable Parsons to accomplish even more in our quest to deliver a better world. Inclusion Inspires Innovation Embracing inclusion, diversity and equality in all aspects of our business is fundamental to our corporate culture and vital to our continued growth and success. Our employees work across 25 countries and collectively speak over 80 languages. Diversity is one of our core values, and we pursue it in our workforce, our markets, our suppliers, and our services because we recognize that optimum solutions require different backgrounds, new perspectives, and open minds. We leverage diversity and equality through the inclusion of employees, empowering them to shape the future of the corporation through collaboration and innovation. In 2017, we launched our Inclusion and Diversity (I&D) Task Force with executive sponsorship from the Board, our CEO, our President and COO, and our Chief People Officer. The task force’s objectives are to attract, include, and retain talent, and to help achieve those goals. Its 42 diverse members serve as ambassadors throughout the corporation, demonstrate leadership, and infuse their passion for inclusion and diversity into our corporate culture. Within the task force, subcommittees support the development and implementation of initiatives identified by the Board and the Executive Leadership Team that continue to advance our inclusion and diversity objectives. Subcommittees and Purpose • Metrics – Measure the success of inclusion and diversity • Ambassadors – Bring inclusion and diversity to the local level to create inclusion and diversity awareness • Mentoring/Training – Drive improved awareness and engagement 13 • Communications – Promote inclusion and diversity awareness through messaging and celebration • Executive/Intern Diversity – Drive improved diversity at the intern and executive levels • • Policy Review – Improve inclusion and diversity through policy change Social Justice and Equality – Advance social justice and equality inside and outside of Parsons • Military and Veterans Affairs – Attract veterans and cultivate their careers and success • Pride Alliance – Advocate for the LGBTQ+ With recent social justice and equality awakening, we launched the Listen-Learn-Action campaign. Our Board and our CEO and Chairman implemented a thoughtful strategy to better understand the perspectives of our employees by listening to them through various forums, then sharing the understanding and offering educational resources to all employees, and, finally, putting into effect a concise, iterative quarterly action plan that holds us accountable to doing more to increasing the representation or historically underrepresented groups within our global workforce, and we are committed to taking action and ensuring Parsons is, and remains, an employer of choice. Employee Stock Ownership Plan At December 31, 2020, approximately 6,300 of our employees participated in our Employee Stock Ownership Plan (ESOP), which owns approximately 39% of our outstanding shares. In December 2020, the board of directors approved an amendment to the ESOP to provide greater diversification rights to participants. The amendment provides that, with respect to all diversifications elected or processed after January 1, 2021, the definition of a qualified participant shall mean a participant who has attained the age of 50 and who has completed at least three years of participation in the ESOP and other criteria. Each qualified participant shall generally be permitted to direct the ESOP as to the diversification of 50% of the value of the eligible vested portion of the participant’s ESOP account. Further, in January 2021, the Parsons Corporation Board of Directors approved an amendment to the ESOP whereby distributions to participants in the Plan were modified as follows: (1) the threshold amount of an ESOP participant’s balance to be eligible for a single lump sum distribution was increased from $20,000 or less to $500,000 or less; (2) the threshold balance for a participant to be eligible to receive payment in two annual installments was increased from $40,000 or less to $750,000 or less; and (3) the threshold balance for a participant to be eligible to receive payment in three annual installments was increased to greater than $750,000. This change was made to facilitate greater flexibility for certain eligible participants to receive their balances in fewer installments and to accelerate the increase in publicly traded float for the Company’s common stock. Intellectual Property Our intellectual property portfolio consists of issued and pending patents as well as trademarks for many of our technologies. In addition, we maintain a number of trade secrets that we endeavor to protect to ensure their continuing availability to us. Our technical expertise is vital to our growth strategy, and we believe they are a core competitive advantage. We have 26 registered patents and 31 pending patents in the United States and 4 pending patents internationally. We have 67 trademarks and 26 pending trademark applications in the United States, and 145 trademarks and 34 pending trademark applications internationally. We also currently offer 25 products for sale to our global customers. We rely upon a combination of nondisclosure agreements and other contractual arrangements, as well as copyright, trademark, patent and trade secret laws to protect our proprietary information. We also enter into proprietary information and intellectual property agreements with employees, which require them to disclose any inventions created during employment, to convey such rights to inventions to us and to restrict any disclosure of proprietary information. While protecting trade secrets and proprietary information is important, we are not materially dependent on maintenance of any specific trade secret or group of trade secrets. 14 During the normal course of business, we perform research and development and technology consulting services and related products in support of our customers. Typically, these services do not depend on patent protection. In accordance with applicable law, our government contracts often provide government agencies certain license rights to our inventions, copyrights and other intellectual property. Government agencies may in turn sublicense to other contractors (including our competitors) the right to utilize our intellectual property. In addition, in the case of our work as a subcontractor, our prime contractor may also have certain rights to data, information and products we develop under the subcontract. At the same time, our government contracts often license to us patents, copyrights and other intellectual property owned by third parties. Regulation Our business is impacted by government procurement, anti-bribery, international trade, environmental, health and safety and other regulations and requirements. Below is a summary of some of the significant regulations that impact our business. Government Procurement. The services we provide to the U.S. Government are subject to Federal Acquisition Regulation, or FAR, the Truth in Negotiations Act, Cost Accounting Standards, or CAS, the Services Contract Act, the False Claims Act, export controls rules and U.S. Department of Defense security regulations, as well as many other laws and regulations. These laws and regulations affect how we transact business with our clients and, in some instances, impose additional costs on our business operations. A violation of specific laws and regulations could lead to fines, contract termination or suspension of future contracts. Generally, our government clients can also terminate, renegotiate, or modify any of their contracts with us at their convenience, and many of our government contracts are subject to renewal or extension annually. In 2019, the U.S. Department of Defense announced the development of Cybersecurity Maturity Model Certification (“CMMC”) as a framework to assess and enhance the cybersecurity posture of the Defense Industrial Base (“DIB”), particularly as it relates to controlled unclassified information within the supply chain. CMMC is designed to ensure that contractors providing services to the U.S. Department of Defense have implemented cybersecurity controls and processes to adequately protect information that resides on DIB systems and networks. The U.S. Department of Defense issued an interim rule on September 29, 2020 to amend the Defense Federal Acquisition Regulation Supplement (DFARS) to include one new provision and two new contract clauses. It became effective on November 30, 2020. We collaborated with other companies to provide feedback following the 60-day public comment period. In December 2020, the U.S. Department of Defense identified seven approved pilots of the expected fifteen for fiscal year 2021 that are new Requests for Proposals which will be incorporated into CMMC requirements. All offerors are expected to undergo appropriate third- party CMMC assessment and achieve certification of Level 3 and below at the time of contract award. We are currently in compliance and is preparing for future certification and assessments. Anti-Bribery and other regulations. We are subject to the U.S. Foreign Corrupt Practices Act and similar anti-bribery laws, which generally prohibit companies and their intermediaries from making improper payments to foreign government officials for the purpose of obtaining or retaining business. The U.K. Bribery Act of 2010 prohibits both domestic and international bribery, as well as bribery across both private and public sectors. In addition, an organization that “fails to prevent bribery” committed by anyone associated with the organization can be charged under the U.K. Bribery Act unless the organization can establish the defense of having implemented “adequate procedures” to prevent bribery. International Trade. We are subject to U.S. export control laws and regulations, including the International Traffic in Arms Regulations, or ITAR, and the Export Administration Regulations, or EAR, as well as U.S. economic and trade sanctions, including those administered and enforced by the U.S. Department of Treasury’s Office of Foreign Assets Control, or OFAC. To the extent we export items and provide services outside of the United States (or to certain parties in the United States), we must do so in compliance with these laws and regulations. These laws and regulations impose export licensing requirements, and we may not be successful in 15 obtaining necessary licenses and other authorizations. Further, these laws and regulations restrict our ability to export items or provide services to certain countries and certain persons, including those that are the target of OFAC sanctions. Noncompliance with these or similar laws could lead to government investigations, penalties, reputational harm, and other negative consequences, and thereby could adversely affect our business and financial condition. Further, any change in these laws and regulations, or any shift in the approach to their enforcement or scope, or change to the countries, persons, or items targeted by such regulations, could potentially result in our decreased ability to export or sell items or services to existing or potential customers. Environmental, Health and Safety. We are subject to federal, state and local laws and regulations relating to environmental, health and safety matters, including, among other things, the handling, transport and disposal of regulated substances and wastes, including hazardous and radioactive materials; contamination by regulated substances and wastes; the types, quantities and concentration of materials that can be released into the environment; the acquisition of a permit or other approval before conducting regulated activities; the maintenance of information about hazardous materials used or produced in operations and provision of such information to employees, state and local government authorities and the public; and employee health and safety. Our previous ownership and current and previous operation of real property may subject us to liability pursuant to these laws or regulations. Under the Comprehensive Environmental Response, Compensation and Liability Act, or CERCLA, and related state laws, certain persons may be liable at sites where or from a release or threatened release of hazardous substances has occurred or is threatened. These persons can include the current owner or operator of property where a release or threatened release occurred, any persons who owned or operated the property when the release occurred, and any persons who disposed of, or arranged for the transportation or disposal of, hazardous substances at a contaminated property. Liability under CERCLA is strict, retroactive and, under certain circumstances, joint and several, so that any responsible party may be held liable for the entire cost of investigating and remediating the release of hazardous substances. The Resource Conservation and Recovery Act, or RCRA, regulates the generation, treatment, storage, handling, transportation and disposal of solid waste and requires states to develop programs to ensure the safe disposal of solid waste. Under RCRA, persons may be liable at sites where the past or present storage, handling, treatment, transportation, or disposal of any solid or hazardous waste may present an imminent and substantial endangerment to health or the environment. These persons can include the current owner or operator of property where disposal occurred, any persons who owned or operated the property when the disposal occurred, and any persons who disposed of, or arranged for the transportation or disposal of, hazardous substances at a contaminated property. Liability under RCRA is strict and, under certain circumstances, joint and several, so that any responsible party may be held liable for the entire cost of investigating and remediating the release of hazardous substances. Violations and liabilities with respect to environmental, health and safety laws and regulations could result in significant administrative, civil, or criminal penalties, remedial clean-ups, natural resource damages, permit modifications or revocations, operational interruptions or shutdowns and other liabilities. Additionally, Congress, state legislatures, local governing bodies and federal and state agencies frequently revise environmental laws and regulations, and any changes could result in more stringent or costly requirements for our operations. Our costs related to complying with environmental, health and safety laws and regulations have not been material in the past and are not currently material to our total operating costs or cash flows. However, if we have any violations of, or incur liabilities pursuant to these laws or regulations in the future, our financial condition and operating results could be adversely affected. In addition, in the unlikely event that we are required to fund remediation of a contaminated site, the statutory framework might allow us to pursue rights of contribution from other potentially responsible parties. We maintain a compliance program designed to ensure compliance with the various regulations and requirements applicable to us. The compliance program, managed by our Chief Ethics and Compliance Counsel and overseen by our Chief Compliance Officer, includes an annual audit of performance with respect to our codes of ethics and business conduct and the adequacy of our compliance program, among other initiatives. 16 Executive Officers Charles L.

Risk Relating to Our Business • Our business, results of operations, financial condition, cash flows and stock price can be adversely affected by pandemics, epidemics or other public health emergencies, such as the current global COVID-19 pandemic and post-pandemic impacts. • Government spending and priorities could change in a manner that adversely affects our future revenue and limits our growth prospects. • The U.S. federal government and its agencies collectively are our largest single customer and, if our reputation or relationships with the U.S. federal government were harmed, our future revenues and cash flows would be adversely affected. • Our failure to comply with a variety of complex procurement rules and regulations could result in our being liable for penalties, including termination of our government contracts, disqualification from bidding on future government contracts and suspension or debarment from government contracting. 18 • A substantial portion of our business is subject to reviews, audits and cost adjustments by government agencies, which, if resolved unfavorably to us, could adversely affect our profitability, cash flows or growth prospects. • Our government contracts may be terminated by the government counterparty at any time and may contain other provisions permitting the government to discontinue contract performance, and if lost contracts are not replaced, our operating results may differ materially and adversely from those anticipated. • Our revenue and growth prospects may be harmed if we or our employees are unable to obtain government granted eligibility or other qualifications, we and they need to perform services for our customers. • We may make acquisitions, investments, joint ventures and divestitures in the future that involve numerous risks, which if realized, may adversely affect our business and our future results. • Our acquisitions may not achieve their full intended benefits or may disrupt our plans and operations. • We conduct a portion of our work through joint venture entities, some of which we do not have management control over, and with which we typically have joint and several liability with our joint venture partners. • Our earnings and profitability may vary based on the mix of our contracts and may be adversely affected by our failure to accurately estimate and manage costs, time and resources. • We use estimates in recognizing revenues and, if we make changes to estimates used in recognizing revenues, our profitability may be adversely affected. • • • Systems that we develop, integrate, maintain, or otherwise support could experience security breaches which may damage our reputation with our clients and hinder future contract win rates. Services we provide and technologies we develop are designed to detect and monitor threats to our clients, the failure of which may lead to reputational harm or liability against us by our clients or third parties and may subject our staff to potential threats, risk of loss or harm. Internal system or service failures affecting us or our vendors, including as a result of cyber or other security threats, could disrupt our business and impair our ability to effectively provide our services to our clients, which could damage our reputation and have a material adverse effect on our business, financial condition and results of operations. • Our business is subject to numerous legal and regulatory requirements and any violation of these requirements or any misconduct by our employees, subcontractors, agents or business partners could harm our business and reputation. • Goodwill and intangible assets represent a significant amount of our total assets and any impairment of these assets would negatively impact our results of operations. • We depend on our teaming arrangements and relationships with other contractors and subcontractors. If we are not able to maintain these relationships, or if these parties fail to satisfy their obligations to us or the customer, our revenues, profitability and growth prospects could be adversely affected. • Many of our contracts require innovative design capabilities, are technologically complex or are dependent upon factors not wholly within our control. Failure to meet these obligations could adversely affect our business, financial condition or results of operations. • Assertions by third parties of infringement, misappropriation or other violations by us of their intellectual property rights could result in significant costs and substantially harm our business, financial condition and operation results. • We have operations in the Middle East and neighboring regions, and these regions may experience turmoil that may impact our current projects, future business and financial stability. 19 • We may not realize the full value of our backlog, which may result in lower than expected revenue. • Many of our field project sites and facilities are inherently dangerous workplaces. Failure to manage our field project sites and facilities safely could result in environmental disasters, employee deaths or injuries, reduced profitability, the loss of projects or clients and possible exposure to litigation. Risk Related to Our Common Stock • Your ability to influence corporate matters may be limited because the ESOP beneficially owns a majority of our stock and therefore our employees, voting the shares allocated to them under the ESOP, or the ESOP Trustee, who will have the right to vote shares for which no voting instructions are provided by employees, could have substantial control over us. • We are a “controlled company” within the meaning of the New York Stock Exchange listing standards and, as a result, qualify for exemptions from certain corporate governance requirements. You may not have the same protections afforded to stockholders of companies that are subject to such requirements. Risks Related to the COVID-19 Pandemic Our business, results of operations, financial condition, cash flows and stock price can be adversely affected by pandemics, epidemics or other public health emergencies, such as the current global COVID-19 pandemic. Our business, results of operations, financial condition, cash flows and stock price can be adversely affected by pandemics, epidemics or other public health emergencies, such as the current global COVID-19 pandemic. The pandemic has resulted in governments around the world implementing increasingly stringent measures to help control the spread of the virus, including quarantines, “shelter in place” and “stay at home” orders, travel restrictions, business curtailments, school closures, and other measures. In addition, governments and central banks in several parts of the world have enacted fiscal and monetary stimulus measures to counteract the impacts of the COVID-19 pandemic. Although we have continued our operations consistent with federal guidelines and state and local orders, the outbreak of COVID-19 and any preventive or protective actions taken by governmental authorities [has had and] may [continue to] have a material adverse effect on our operations, employees and customers, including business shutdowns or disruptions. The COVID-19 pandemic is expected to reduce demand for our services and impact client spending in certain circumstances. The extent to which the COVID-19 pandemic may adversely impact our business depends on future developments, which are highly uncertain and unpredictable, depending upon the severity and duration of the outbreak and the effectiveness of actions taken globally to contain or mitigate its effects. Any resulting financial impact cannot be estimated reasonably at this time but may materially adversely affect our ability to collect accounts receivables and our business, results of operations, financial condition and cash flows. Even after the COVID-19 pandemic has subsided, we may experience materially adverse impacts to our business due to any resulting economic recession or depression. Additionally, concerns over the economic impact of the COVID-19 pandemic have caused extreme volatility in financial and other capital markets which has and may continue to adversely impact our stock price and our ability to access capital markets. To the extent the COVID-19 pandemic adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described in this Annual Report on Form 10-K for the year ended December 31, 2020, such as those relating to government spending and priorities. Risks Related to Government Contracts Government spending and priorities could change in a manner that adversely affects our future revenue and limits our growth prospects. We derive, and expect to continue to derive, a significant portion of our revenue from contracts with government entities. As a result, our business depends upon continued government expenditures on defense, 20 intelligence, civil and engineering programs for which we provide support, both among foreign governments and at federal, state and local levels domestically. These expenditures have not remained constant over time and have been reduced in some periods. In particular, these expenditures have recently been affected by efforts to improve efficiency and reduce costs affecting government programs generally. Our business, prospects, financial condition or operating results could be materially harmed, among other causes, by the following: • • • • • • • • • • • • budgetary constraints, including mandated automatic spending cuts, affecting across-the-board government spending, or specific agencies in particular, and changes in available funding; a shift in expenditures away from agencies or programs that we support; reduced government outsourcing of functions that we are currently contracted to provide, including as a result of increased insourcing by various U.S. government agencies due to changes in the definition of “inherently governmental” work, including proposals to limit contractor access to sensitive or classified information and work assignments; further efforts to improve efficiency and reduce costs affecting government programs; changes or delays in government programs that we support or the programs’ requirements; a continuation of recent efforts by the U.S. government in particular to decrease spending for management support service contracts; U.S. government shutdowns due to, among other reasons, a failure by elected officials to fund the government, such as the shutdowns which occurred during government fiscal years 2019 and 2014 and, to a lesser extent, government fiscal year 2018, and other potential delays in the appropriations process; U.S. government agencies awarding contracts on a technically acceptable/lowest cost basis in order to reduce expenditures; delays in the payment of our invoices by government payment offices; results of elections, including politicians who may have priorities that would reduce spending in areas in which we operate; an inability by the U.S. government to fund its operations as a result of a failure to increase the federal government’s debt ceiling, a credit downgrade of U.S. government obligations or for any other reason; and changes in the political climate and general economic conditions, including a slowdown of the economy or unstable economic conditions and responses to conditions, such as emergency spending, that reduce funds available for other government priorities. Any disruption in the functioning of government agencies, including as a result of government closures and shutdowns, terrorism, war, natural disasters, destruction of government facilities, and other potential calamities could have a negative impact on our operations and cause us to lose revenue or incur additional costs due to, among other things, our inability to deploy our staff to client locations or facilities as a result of such disruptions. In particular, with regard to our largest single customer, the U.S. federal government, budget deficits, the national debt and the prevailing economic condition, and actions taken to address them, could continue to negatively affect the U.S. government expenditures on defense, intelligence and civil programs for which we provide support. The U.S. Department of Defense is one of our significant clients and cost cutting, including through consolidation and elimination of duplicative organizations and insourcing, has become a major initiative for the U.S. Department of Defense. There remains uncertainty as to how exactly budget cuts, including sequestration, will impact us, and we are therefore unable to predict the extent of the impact of such cuts on our business and results of operations. However, a reduction in the amount of or delays or cancellations of funding for, services that we are contracted to provide to the U.S. Department of Defense as a result of any of these initiatives, legislation or otherwise could have a material adverse effect on our business, financial condition and 21 results of operations. In addition, in response to an Office of Management and Budget mandate, government agencies have reduced management support services spending in recent years. If federal awards for management support services continue to decline, our revenue and operating profits may materially decline and further efforts by the Office of Management and Budget to decrease federal awards for management support services could have a material and adverse effect on our business, financial condition and results of operations. In addition, most government contracts are subject to the government’s budgetary approval process. Legislatures typically appropriate funds for a given program on a year-by-year basis, even though contract performance may take more than one year. In addition, public-supported financing such as state and local municipal bonds may be only partially raised to support existing infrastructure projects. As a result, at the beginning of a program, the related contract is only partially funded, and additional funding is normally committed only as appropriations are made in each fiscal year. These appropriations, and the timing of payment of appropriated amounts, may be influenced by, among other things, the state of the economy, competing priorities for appropriation, changes in administration or control of legislatures and the timing and amount of tax receipts and the overall level of government expenditures. Similarly, the impact of an economic downturn on state and local governments may make it more difficult for them to fund infrastructure projects. If appropriations are not made in subsequent years on our government contracts, then we will not realize all of our potential revenue and profit from that contract, and we may incur substantial labor costs without reimbursement. Government funding with respect to our Critical Infrastructure services fluctuates over time and new or changing government policies may affect our Critical Infrastructure business and operations. In March 2018, for example, President Trump signed proclamations to impose tariffs on steel and aluminum imports per the U.S. Trade Expansion Act of 1962 increasing the price for steel and aluminum in the United States which could impact client spending. Government spending for our Critical Infrastructure services may also depend on factors related to government demand, such as the condition of the existing infrastructure and buildings and the need for new or expanded infrastructure and buildings. Our government clients may face budget cuts or deficits that prohibit them from funding proposed and existing Critical Infrastructure projects. These or other factors could cause our defense, intelligence, infrastructure or civil clients to decrease the number of new government contracts awarded generally and fail to award us new government contracts, reduce their purchases under our existing government contracts, exercise their right to terminate our government contracts or not exercise options to renew our government contracts, any of which could materially and adversely affect our business, financial condition and results of operations. The U.S. federal government and its agencies collectively are our largest single customer and, if our reputation or relationships with the U.S. federal government were harmed, our future revenues and cash flows would be adversely affected. The U.S. federal government and its agencies, including the military and intelligence community, collectively are our largest customer. In particular, it represents substantially all of the revenue of our Federal Solutions segment. Approximately 49% of our consolidated revenues in 2020, 48% in 2019, and 42% in 2018, and approximately 19% of accounts receivable as of December 31, 2020 and 17% as of December 31, 2019 were derived from contracts with the U.S. federal government and its agencies. Our reputation and relationships with various U.S. government entities and agencies, and in particular with the U.S. Department of Defense, including the Missile Defense Agency and the United States Army, the Federal Aviation Administration, the United States intelligence community and the U.S. Department of Energy are key factors in maintaining and growing these revenues and winning new bids for new business. Negative press reports or publicity, regardless of accuracy, could harm our reputation. If our reputation or relationships with government agencies were to be negatively affected, or if we are suspended or debarred from contracting with government agencies for any reason, the amount of business with government and other customers would decrease and our financial condition and results of operations could be adversely affected. 22 Our failure to comply with a variety of complex procurement rules and regulations could result in our being liable for penalties, including termination of our government contracts, disqualification from bidding on future government contracts and suspension or debarment from government contracting. We must comply with various laws and regulations relating to the formation, administration and performance of government contracts, which affect how we do business with our customers and may impose added costs on our business. Many of our U.S. government contracts contain organizational conflict of interest, or OCI, clauses that may limit our ability to compete for or perform contracts or other types of services for particular customers. OCI arises when we engage in activities that may make us unable to render impartial assistance or advice to the U.S. government, impair our objectivity in performing contract work or provide us with an unfair competitive advantage. Existing OCI, and any OCI that may develop, could preclude our competition for or performance on a significant project or contract, which could limit our opportunities. Some U.S. federal and state statutes and regulations provide for automatic debarment based on our actions, such as violations of the U.S. False Claims Act or the U.S. Foreign Corrupt Practices Act, or FCPA. The suspension or debarment in any particular case may be limited to the facility, contract or subsidiary involved in the violation or could be applied to our entire enterprise in severe circumstances. Even a narrow scope suspension or debarment could result in negative publicity that could adversely affect our ability to renew contracts and to secure new contracts, both with governments and private customers, which could materially and adversely affect our business, financial condition and results of operations. Governments may adopt new contract rules and regulations or revise their procurement practices in a manner adverse to us at any time. The government-related industries within which we do business continue to experience significant changes to business practices as a result of an increased focus on affordability, efficiencies and recovery of costs, among other items. Our existing and potential clients are similarly focused on increasing the productivity of their contractual arrangements. Moreover, government agencies may face restrictions or pressure regarding the type and amount of services that they may obtain from private contractors. Legislation, regulations and initiatives dealing with procurement reform, mitigation of potential OCIs, deterrence of fraud, and environmental responsibility or sustainability could have an adverse effect on us. Moreover, shifts in the buying practices of government agencies, such as increased usage of fixed price contracts, multiple award contracts and small business set-aside contracts, could have adverse effects on government contractors, including us. Any of these changes could impair our ability to obtain new contracts or contract renewals. Any new contracting requirements or procurement methods could be costly or administratively difficult for us to implement and could adversely affect our business, financial condition and results of operations. A substantial portion of our business is subject to reviews, audits and cost adjustments by government agencies, which, if resolved unfavorably to us, could adversely affect our profitability, cash flows or growth prospects. Government agencies routinely audit and review a contractor’s performance on government contracts, indirect cost rates and pricing practices, and compliance with applicable contracting and procurement laws, regulations and standards. They also review the adequacy of the contractor’s compliance with government standards for its business systems, which are defined as the contractor’s accounting, earned value management, estimating, materials management, property management and purchasing systems. A finding of significant control deficiencies in a contractor’s business systems or a finding of noncompliance with U.S. government Cost Accounting Standards, or CAS, can result in decremented billing rates to U.S. government customers until the control deficiencies are corrected and their remediation is accepted by the Defense Contract Management Agency. The agencies conducting these audits and reviews have come under increased scrutiny. As a result, audits and reviews have become more rigorous and the standards to which we are held are being more strictly interpreted which has increased the likelihood of an audit or review resulting in an adverse outcome. 23 If a review or investigation by a government agency identifies improper or illegal activities, we may be subject to civil or criminal penalties or administrative sanctions which could include the termination of contracts, forfeiture of profits, the triggering of price reduction clauses, suspension of payments, fines, and suspension or debarment from doing business with governmental agencies. We may suffer harm to our reputation if allegations of impropriety are made against us, which would impair our ability to win new contract awards or receive contract renewals. Penalties and sanctions are not uncommon in our industries. If we incur a material penalty or administrative sanction or otherwise suffer harm to our reputation, our profitability, cash position and future prospects could be adversely affected. Government audits and reviews may conclude that our practices are not consistent with applicable laws and regulations and result in adjustments to contract costs and mandatory customer refunds. Such adjustments can be applied retroactively, which could result in significant customer refunds, and those refunds would negatively impact our revenue. Receipt of adverse audit findings or the failure to obtain an “approved” determination on our various business systems could significantly and adversely affect our business by, among other things, restricting our ability to bid on new contracts and, for those proposals under evaluation, diminishing our competitive position. A determination of noncompliance could also result in penalties and sanctions against us, including withholding of payments, suspension of payments and increased government scrutiny. Increased scrutiny could adversely impact our ability to perform on contracts, affect our ability to invoice for work performed, delay the receipt of timely payment on contracts, and weaken our ability to compete for new contracts with the government. Our government contracts may be terminated by the government counterparty at any time and may contain other provisions permitting the government to discontinue contract performance, and if lost contracts are not replaced, our operating results may differ materially and adversely from those anticipated. Government contracts often contain provisions and are subject to laws and regulations that provide government clients with rights and remedies not typically found in commercial contracts. These rights and remedies allow government clients, among other things, to: • • • • • • • • terminate existing contracts, with short notice, for convenience as well as for default; reduce orders under or otherwise modify contracts; for contracts subject to the Truth in Negotiations Act, reduce the contract price or cost where it was increased because a contractor or subcontractor furnished cost or pricing data during negotiations that was not complete, accurate and current; for some contracts, (1) demand a refund, make a forward price adjustment or terminate a contract for default if a contractor provided inaccurate or incomplete data during the contract negotiation process and (2) reduce the contract price under triggering circumstances, including the revision of price lists or other documents upon which the contract award was predicated; terminate our facility security clearances and thereby prevent us from receiving classified contracts and complete work on existing contracts; cancel multi-year contracts and related task orders if funds for contract performance for any subsequent year become unavailable; decline to exercise an option to renew a multi-year contract or issue task orders in connection with indefinite delivery/indefinite quantity contracts, or IDIQ contracts; claim rights in solutions, systems and technology produced by us, appropriate such work-product for their continued use without continuing to contract for our services and disclose such work-product to third parties, including other government agencies and our competitors, which could harm our competitive position; 24 • • • • prohibit future procurement awards with a particular agency due to a finding of organizational conflicts of interest based upon prior related work performed for the agency that would give a contractor an unfair advantage over competing contractors, or the existence of conflicting roles that might bias a contractor’s judgment; subject the award of contracts to protest by competitors, which may require the contracting federal agency or department to suspend our performance pending the outcome of the protest and may also result in a requirement to resubmit offers for the contract or in the termination, reduction or modification of the awarded contract; suspend or debar us from doing business with the applicable government; and control or prohibit the export of our services. Recent and potential future budget cuts, the impact of sequestration and recent efforts by the Office of Management and Budget to decrease federal awards for management support services, may cause agencies with which we currently have contracts to terminate, reduce the number of task orders under or fail to renew such contracts. If a government client were to unexpectedly terminate, cancel, or decline to exercise an option to renew with respect to one or more of our significant contracts, or suspend or debar us from doing business with such government, our revenue and operating results would be materially harmed. Our revenue and growth prospects may be harmed if we or our employees are unable to obtain government granted eligibility or other qualifications, we and they need to perform services for our customers. A number of government programs require contractors to have certain kinds of government granted eligibility, such as security clearance credentials. Depending on the project, eligibility can be difficult and time- consuming to obtain. If we or our employees are unable to obtain or retain the necessary eligibility, including local ownership requirements, we may not be able to win new business, and our existing customers could terminate their contracts with us or decide not to renew them. To the extent we cannot obtain or maintain the required security clearances for our employees working on a particular contract, we may not derive the revenue or profit anticipated from such contract. Risks Related to Our Operations and Markets Our profitability could suffer if we are not able to timely and effectively utilize our employees or manage our cost structure. The cost of providing our services, including the degree to which our employees are utilized, affects our profitability. The degree to which we are able to utilize our employees in a timely manner or at all is affected by a number of factors, including: • • • • • • our ability to transition employees from completed projects to new assignments and to hire, assimilate and deploy new employees; our ability to forecast demand for our services and to maintain and deploy headcount that is aligned with demand, including employees with the right mix of skills and experience to support our projects; our employees’ inability to obtain or retain necessary security clearances or required certifications; changes to or delays or cancellations of projects, as a result of governmental budgetary processes or otherwise; our ability to manage attrition; and our need to devote time and resources to training, business development, and other non-chargeable activities. 25 If our employees are under-utilized, our profit margin and profitability could suffer. Additionally, if our employees are over-utilized, it could have a material adverse effect on employee morale and attrition, which would in turn have a material adverse impact on our business, financial condition or results of operations. Our profitability is also affected by the extent to which we are able to effectively manage our overall cost structure for operating expenses, such as wages and benefits, real estate expenses, overhead and capital and other investment-related expenditures. If we are unable to effectively manage our costs and expenses and achieve efficiencies, our competitiveness and profitability may be adversely affected. Our focus on new growth areas for our business entails risks, including those associated with new relationships, clients, talent needs, capabilities, service offerings and maintaining our collaborative culture and core values. We are focused on growing our presence in our addressable markets by enhancing and optimizing our core operations, extending into opportunity-rich adjacent markets and acquiring and integrating transformative, disruptive technologies. These efforts entail inherent risks associated with innovation and competition from other participants in those areas, potential failure to help our clients respond to the challenges they face, our ability to comply with uncertain evolving legal standards applicable to some of our service offerings, including those in the cybersecurity area, and, with respect to potential international growth, risks associated with operating in foreign jurisdictions, such as compliance with applicable foreign and U.S. laws and regulations that may impose different and, occasionally, conflicting or contradictory requirements, and the economic, legal, and political conditions in the foreign jurisdictions in which we operate, as described in additional detail below. As we attempt to develop new relationships, clients, capabilities, and service offerings, these efforts could harm our results of operations due to, among other things, a diversion of our focus and resources and actual costs, opportunity costs of pursuing these opportunities in lieu of others and a failure to reach a profitable return on our investments in new technologies, capabilities, and businesses, including expenses on research and development investments, and these efforts could ultimately be unsuccessful. Additionally, the possibility exists that our competitors might develop new capabilities or service offerings that might cause our existing capabilities and service offerings to become obsolete. If we fail in our new capabilities development efforts or our capabilities or services fail to achieve market acceptance more rapidly than our competitors, our ability to procure new contracts could be negatively impacted, which would negatively impact our results of operations and our financial condition. In addition, our ability to grow our business by leveraging our operating model to efficiently and effectively deploy our people across our client base is largely dependent on our ability to maintain our collaborative culture. To the extent that we are unable to maintain our culture for any reason, including our effort to focus on new growth areas or acquire new businesses with different corporate cultures, we may be unable to grow our business. Any such failure could have a material adverse effect on our business, financial condition and results of operations. With the growth of our U.S. and international operations, we are now providing client services and undertaking business development efforts in numerous and disparate geographic locations both domestically and internationally. Our ability to effectively serve our clients is dependent upon our ability to successfully leverage our operating model across all of these and any future locations, maintain effective management controls over all of our locations to ensure, among other things, compliance with applicable laws, rules and regulations, and instill our core values in all of our personnel at each of these and any future locations. Any inability to ensure any of the foregoing could have a material adverse effect on our business, financial condition and results of operations. 26 We have submitted claims to clients for work we performed beyond the initial scope of some of our contracts. If these clients do not approve these claims, our results of operations could be adversely impacted. We typically have pending claims submitted under some of our contracts for payment of work performed beyond the initial contractual requirements for which we have already recorded revenue. Some of these relate to change orders from the original scope of the contract. Our client may dispute these change orders and claims, and we cannot guarantee that such claims will be approved in whole, in part, or at all. Often, these claims and disputes can be the subject of lengthy arbitration or litigation proceedings, and it is difficult to accurately predict when these claims and disputes will be fully resolved. We may also renegotiate contracts to address these additional costs. When these types of events occur, we have used working capital in projects to cover cost overruns. If our claims are not approved or resolved, our revenue may be reduced in future periods. Many of our contracts require innovative design capabilities, are technologically complex or are dependent upon factors not wholly within our control. Failure to meet these obligations could adversely affect our business, financial condition or results of operations. We design and develop technologically advanced and innovative products and services applied by our customers in a variety of environments. Problems and delays in development or delivery as a result of issues with respect to design, technology, licensing and patent rights, labor, learning curve assumptions or materials and components could prevent us from achieving contractual requirements. Our offerings cannot be tested and proven in all situations and are otherwise subject to unforeseen problems that could negatively affect revenue and profitability such as problems with governmental inaction, quality and workmanship, delivery of subcontractor components or services, unplanned degradation of product performance, unavailability of vendor materials and changes in the project scope requested by our clients. Among the factors that may adversely affect our business, financial condition or results of operations could be unforeseen costs and expenses not covered by insurance or indemnification from the customer, diversion of management focus in responding to unforeseen problems, loss of follow-on work, damage to our reputation and repayment to the customer of contract cost and fee payments we previously received. We face aggressive competition that can impact our ability to obtain contracts and may affect our future revenues, profitability and growth prospects. We expect that a majority of the business that we seek in the foreseeable future will be awarded through a competitive bidding process. For example, the U.S. government increasingly relies on IDIQ, GSA Schedule and other multi-award contracts, which has resulted in greater competition and increased pricing pressure. The competitive bidding process involves substantial costs and a number of risks, including significant cost and managerial time to prepare bids and proposals for contracts that may not be awarded to us, or that may be awarded but for which we do not receive meaningful task orders. For contracts awarded to us, we also face the risk of inaccurately estimating the resources and costs that will be required to fulfill any contract we win. Following contract award, we may encounter significant expense, delay, contract modifications or even contract loss as a result of our competitors protesting the award of contracts to us in competitive bidding. Any resulting loss or delay of startup and funding of work under protested contract awards may adversely affect our revenues and/or profitability. In addition, multi-award contracts require that we make sustained post-award efforts to obtain task orders under the contract. As a result, we may not be able to obtain these task orders or recognize revenues under these multi award contracts. Our failure to compete effectively in this procurement environment would adversely affect our business, financial condition and results of operations. Projects may be awarded based solely upon price, but often take into account other factors, such as technical qualifications, proposed project team, schedule and past performance on similar projects. We compete with larger companies that have greater name recognition, financial resources and larger technical staffs and with smaller, more specialized companies that are able to concentrate their resources on particular areas. Additionally, we may compete with a government’s own capabilities. Technology-focused companies may also develop 27 products and services that could disrupt our business or compete with our services. To remain competitive, we must consistently provide superior service, technology and performance on a cost-effective basis to our customers and there is no assurance that we will do so. Risks Related to Acquisitions and Joint Ventures We may make acquisitions, investments, joint ventures and divestitures in the future that involve numerous risks, which if realized, may adversely affect our business and our future results. We may make strategic acquisitions, engage in joint ventures or divest existing businesses, which could cause us to incur unforeseen expenses and have disruptive effects on our business and may not yield the benefits we expect. Our Credit Agreement imposes limitations on our ability to make other acquisitions. Subject to those limitations, we may selectively pursue additional strategic acquisitions, investments and joint ventures in the future. Any future acquisitions, investments and joint ventures may pose many risks that could adversely affect our reputation, operations or financial results, including: • we may not retain key employees (including those with needed security clearances), customers and business partners of an acquired business in the future; • we may fail to successfully integrate acquired businesses, such as failing to successfully integrate information technology and other control systems relating to the operations of any acquired business; • acquisitions normally require a significant investment of time and resources, which may disrupt our business and distract our management from other important responsibilities; • we may not be able to accurately estimate the financial effect of any acquisitions and investments on our business and we may not realize anticipated revenue opportunities, cost savings, or other synergies or benefits, or acquisitions may not result in improved operating performance; and • we may assume known as well as unknown material liabilities, legal or regulatory risks that were not identified as part of our due diligence or for which we are unable to receive a purchase price adjustment or reimbursement through indemnification. If any acquisitions, investments or joint ventures fail, perform poorly or their value is otherwise impaired for any reason, including contractions in credit markets and global economic conditions, our business, financial condition and results of operations could be adversely affected. In addition, we may periodically divest or plan to divest businesses, including businesses that are no longer a part of our ongoing strategic plan. These divestitures similarly require significant investment of time and resources and may disrupt our business, distract management from other responsibilities and may result in losses on disposal or continued financial involvement in the divested business, including through indemnification, guarantee or other financial arrangements, for a period of time following the transaction, which could adversely affect our business, financial condition or results of operations. When we determine that we would like to divest a business, we may not be able to divest that business on attractive terms or at all. We conduct a portion of our work through joint venture entities, some of which we do not have management control over, and with which we typically have joint and several liability with our joint venture partners. 11.5% of our revenue during fiscal 2020, 12.0% of our revenue during fiscal 2019 and 15.2% of our revenue during fiscal 2018 was derived from our operations through consolidated joint ventures. In addition, 4.4% of our revenue during fiscal 2020, 4.0% of our revenue during fiscal 2019 and 4.1% of our revenues in fiscal 2018 related to services we provided to our unconsolidated joint ventures, where control resides with unaffiliated third parties, and 16.9% of our operating income during fiscal 2020, 45.3% of our operating income during fiscal 2019 28 and 18.0% of our operating income during fiscal 2018 was derived from equity in our unconsolidated joint ventures. As with most joint venture arrangements, differences in views among the joint venture participants may result in delayed decisions or disputes. We also cannot control the actions of our joint venture partners and we typically have joint and several liability with our joint venture partners under the applicable contracts for joint venture projects. These factors could potentially adversely impact the business and operations of a joint venture and, in turn, our business and operations. Operating through joint ventures in which we are a minority holder results in us having limited control over many decisions made with respect to projects and internal controls relating to projects. We generally do not have control of these unconsolidated joint ventures. These joint ventures may not be subject to the same requirements regarding internal controls and internal control over financial reporting that we follow. As a result, internal control problems may arise with respect to these joint ventures, which could have a material adverse effect on our business, financial condition and results of operations and could also affect our reputation in the industries we serve. We participate in joint ventures where we provide guarantees and may be adversely impacted by the failure of such joint venture or its participants to fulfill their obligations. We have investments in and commitments to joint ventures with unrelated parties. These joint ventures from time to time may borrow money to help finance their activities and, in some circumstances, we may be required to provide guarantees of the obligations of our affiliated entities. At December 31, 2020, we had $59.3 million of letters of credit and guarantees that relate to joint ventures. If these entities are not able to honor their obligations under the guarantees, we may be required to expend additional resources or suffer losses, which could be significant. Our acquisitions may not achieve their full intended benefits or may disrupt our plans and operations. We cannot assure you that we will be able to successfully integrate acquired companies with our business or otherwise realize the expected benefits of our acquisitions. For example, in the last several years we have made four large acquisitions. The combination of multiple independent businesses will be a complex, costly, and time- consuming process. Our business may be negatively impacted following acquisitions if we are unable to effectively manage our expanded operations. The integration process will require significant time and focus from our management team and may divert attention from the day-to-day operations of the combined business. Additionally, consummation of acquisitions could disrupt our current plans and operations, which could delay the achievement of our strategic objectives. The expected synergies and operating efficiencies of the acquisitions may not be fully realized, which could result in increased costs and have a material adverse effect on our business, financial condition and results of operations. In addition, the overall integration of the businesses may result in material unanticipated problems, expenses, liabilities, competitive responses, loss of customer relationships and diversion of management’s attention, among other potential adverse consequences. The risks of combining our operations of the businesses include, among others: • we may have underestimated the costs to integrate the information systems of acquired companies with ours; • we may face difficulties in integrating employees, integrating different corporate cultures and in attracting and retaining key personnel; and • we may face challenges in keeping existing contracts and customers. Many of these risks will be outside of our control and any one of them could result in increased costs, decreases in the amount of expected revenue, and diversion of our management’s time and energy, which could 29 have a material adverse effect on our business, financial condition and results of operations. In addition, even if our operations are integrated successfully, we may not realize the full benefits of the acquisitions, including the synergies, operating efficiencies, or sales or growth opportunities that are expected. These benefits may not be achieved within the anticipated time frame or at all. We depend on our teaming arrangements and relationships with other contractors and subcontractors. If we are not able to maintain these relationships, of if these parties fail to satisfy their obligations to us or the customer, our revenues, profitability and growth prospects could be adversely affected. We rely on teaming relationships with other prime contractors and subcontractors in order to submit bids for large procurements or other opportunities where we believe the combination of services, products, and solutions provided by us and our teammates will help us to win and perform the contract. Our future revenues and growth prospects could be adversely affected if the other contractors eliminate or reduce their contract relationships with us, of if our government clients terminate or reduce these other contractors’ programs, do not award them new contracts or refuse to pay under a contract. Companies that do not have access to government contracts or experience with our customers may perform services as our subcontractor that we cannot otherwise provide ourselves, and that exposure could enhance such companies’ prospects of securing a future position as a prime government contractor which could increase competition for future contracts and impair our ability to win these contracts. Whenever our subcontractors fail to timely meet their contractual obligations, have regulatory compliance or other problems, our ability to fulfill our obligations as a prime contractor or higher tier subcontractor may be jeopardized. Subcontractor performance deficiencies under subcontracts with us as the prime contractor could lead to significant losses in future periods and could result in our termination for default as the prime contractor even though it was the subcontractor that failed to perform and not our personnel. Risks Related to Estimates and Accounting Our earnings and profitability may vary based on the mix of our contracts and may be adversely affected by our failure to accurately estimate and manage costs, time and resources. We generate revenue under various types of contracts, which include time-and-materials, cost-plus and fixed-price contracts. Our earnings and profitability may vary materially depending on changes in the proportionate amount of revenues derived from each type of contract, the nature of services or solutions provided, as well as the achievement of performance objectives and the stage of performance at which the right to receive fees, particularly under incentive fee contracts, is finally determined. Cost-plus and time-and-materials contracts generally have lower profitability than fixed-price contracts. To varying degrees, each of our contract types involves some risk that we could underestimate the costs and resources necessary to fulfill the contract. Our profitability is adversely affected when we incur costs on cost-plus and time-and-materials contracts that we cannot bill to our customers. While fixed-price contracts allow us to benefit from cost savings, these contracts also increase our exposure to the risk of cost overruns. Revenue derived from fixed-price contracts represented 32% of our total revenue during fiscal 2020, 30% of our total revenue during fiscal 2019, and 32% of our total revenue during fiscal 2018. When making proposals on fixed-price contracts, we rely heavily on our estimates of costs, scope and timing for completing the associated projects, as well as assumptions regarding technical issues. In particular, contracts in our Critical Infrastructure segment are often won in a hard-bid process, in which clients primarily select the lowest price from a qualified bidder with the understanding that they will not pay above the bid amount, even if we perform work beyond the initial scope of our contract. In each case, our failure to accurately estimate costs, scope or the resources and technology needed to perform our contracts or to effectively manage and control our costs during the performance of work could result, and in some instances has resulted, in reduced profits or in losses. More 30 generally, any increased or unexpected costs or unanticipated delays in connection with the performance of our contracts, including costs and delays caused by contractual disputes or other factors outside of our control, such as performance failures of our subcontractors, natural disasters or other force majeure events, could make our contracts less profitable than expected or unprofitable. We use estimates in recognizing revenues and, if we make changes to estimates used in recognizing revenues, our profitability may be adversely affected. A significant portion of our contract revenues are recognized using the cost-to-cost measure of progress method. This method requires estimates of total costs at completion or measurement of progress towards completion. Particularly due to the technical nature of the services being performed and the length of the contracts, this estimation process is complex and involves significant judgment. Adjustments to original estimates are often required as work progresses, experience is gained and additional information becomes known, even though the scope of the work required under the contract may not change. Any adjustment as a result of a change in estimate is recognized immediately. Changes in the underlying assumptions, circumstances or estimates could result in adjustments that may adversely affect our financial results of operations. Goodwill and intangible assets represent a significant amount of our total assets and any impairment of these assets would negatively impact our results of operations. As of December 31, 2020, we had goodwill and intangible assets of $1.5 billion. Goodwill is tested for impairment annually, or more often if indicators of potential impairment exist, and intangible assets are tested for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Examples of events or changes in circumstances indicating that the carrying value of goodwill may not be recoverable could include a significant adverse change in legal factors or in the business climate, an adverse action or assessment by a regulator, unanticipated competition, loss of key contracts, customer relationships, or personnel that affect current and future operating cash flows of the reporting unit. Any future impairment of goodwill or other intangible assets would have a negative impact on our profitability and financial results. Risks Related to Technology Systems Systems that we develop, integrate, maintain, or otherwise support could experience security breaches which may damage our reputation with our clients and hinder future contract win rates. We develop, integrate, maintain, or otherwise support systems and provide services that include managing and protecting information involved in intelligence, national security and other sensitive or classified government functions. Our systems also store and process sensitive information for commercial clients. The cyber and security threats that our clients face have grown more frequent and sophisticated. A security breach in one of these systems could cause serious harm to our business, damage our reputation, and prevent us from being eligible for further work on sensitive systems for government or commercial clients. Work for non-government and commercial clients involving the protection of information systems or that store clients’ information could also be harmed due to associated security breaches. Damage to our reputation or limitations on our eligibility for additional work or any liability resulting from a security breach in one of the systems we develop, install, maintain, or otherwise support could have a material adverse effect on our business, financial condition and results of operations. Services we provide and technologies we develop are designed to detect and monitor threats to our clients, the failure of which may lead to reputational harm or liability against us by our clients or third parties and may subject our staff to potential threats, risk of loss or harm. We help our clients detect, monitor and mitigate threats to their people, information and facilities. These threats may originate from nation states, terrorist or criminal actors, activist hackers or others who seek to harm 31 our clients. There are many factors, some of which are beyond our control, which could result in the failure of our products to detect, monitor or mitigate these threats. Successful attacks on our clients may cause physical or reputational harm to us and our clients, as well as lead to liability claims against us by our clients or third parties, particularly if such attacks are a result of a failure or perceived failure of our services or technologies. In addition, as a result of our involvement with some clients or projects, our staff, information and facilities may be targeted by these or other threat actors and may be at risk for loss, or physical or reputational harm. Internal system or service failures affecting us or our vendors, including as a result of cyber or other security threats, could disrupt our business and impair our ability to effectively provide our services to our clients, which could damage our reputation and have a material adverse effect on our business, financial condition and results of operations. We create, implement, and maintain information technology and engineering systems and also use vendors to provide services that are often critical to our clients’ operations, some of which involve sensitive information and may be conducted in war zones or other hazardous environments, or include information whose confidentiality is protected by law. As a result, we may be subject to systems or service failures, not only resulting from our own failures or the failures of third-party service providers, natural disasters, power shortages, or terrorist attacks, but also from continuous exposure to cyber and other security threats, including computer viruses and malware, attacks by computer hackers or physical break-ins. There has been an increase in the frequency and sophistication of the cyber and security threats we face, with attacks ranging from those common to businesses generally to those that are more advanced and persistent, which may target us because, as a cybersecurity services contractor, we hold classified, controlled unclassified and other sensitive information. As a result, we and our vendors face a heightened risk of a security breach or disruption resulting from an attack by computer hackers, foreign governments, and cyber terrorists. While we put in place policies, controls and technologies to help detect and protect against such attacks, we cannot guarantee that future incidents will not occur, and if an incident does occur, we may not be able to successfully mitigate the impact. We have been the target of these types of attacks in the past and future attacks are likely to occur. If successful, these types of attacks on our network or other systems or service failures could have a material adverse effect on our business, financial condition and results of operations, due to, among other things, the loss of client or proprietary data, interruptions or delays in our clients’ businesses and damage to our reputation. In addition, the failure or disruption of our systems, communications, vendors, or utilities could cause us to interrupt or suspend our operations, which could have a material adverse effect on our business, financial condition and results of operations. In addition, if our employees inadvertently do not adhere to appropriate information security protocols, our protocols are inadequate, or our employees intentionally avoid these protocols, our or our clients’ sensitive information may be released thereby causing significant negative impacts to our reputation and exposing us or our clients to liability. If our or our vendors’ systems, services or other applications have significant defects or errors, are successfully attacked by cyber and other security threats, suffer delivery delays or otherwise fail to meet our clients’ expectations, we may: • • • • • • lose revenue due to adverse client reaction; be required to provide additional services to a client at no charge; incur additional costs related to remediation, monitoring and increasing our cybersecurity; lose revenue due to the deployment of internal staff for remediation efforts instead of client assignments; receive negative publicity, which could damage our reputation and adversely affect our ability to attract or retain clients; be unable to successfully market services that are reliant on the creation and maintaining of secure information technology systems to government and commercial clients; 32 • • suffer claims by clients or impacted third parties for substantial damages, particularly as a result of any successful network or systems breach and exfiltration of client and/or third-party information; or incur significant costs, including fines from government regulators related to complying with applicable federal or state law, including laws pertaining to the security and protection of personal information. In addition to any costs resulting from contract performance or required corrective action, these failures may result in increased costs or loss of revenue if they result in clients postponing subsequently scheduled work or canceling or failing to renew contracts. The costs related to cyber or other security threats or disruptions may not be fully insured or indemnified by other means. Additionally, some cyber technologies and techniques that we utilize or develop may raise potential liabilities related to legal compliance, intellectual property and civil liberties, including privacy concerns, which may not be fully insured or indemnified. We may not be able to obtain and maintain insurance coverage on reasonable terms or in sufficient amounts to cover one or more large claims, or the insurer may disclaim coverage as to some types of future claims. The successful assertion of any large claim against us could seriously harm our business. Even if not successful, these claims could result in significant legal and other costs, may be a distraction to our management, and may harm our client relationships. In some new business areas, we may not be able to obtain sufficient insurance and may decide not to accept or solicit business in these areas. As a contractor supporting defense and national security clients, we are also subject to regulatory compliance requirements under the Defense Federal Acquisition Regulation Supplement and other federal regulations requiring that our networks and information technology systems comply with the security and privacy controls in National Institute of Standards and Technology Special Publications. To the extent that we do not comply with the applicable security and control requirements, whether imposed by regulation or contract, unauthorized access or disclosure of sensitive information could potentially result in a contract termination that has a material adverse effect on our business, financial condition and results of operations and reputational harm. Risk Related to Legal Matters and Insurance Unavailability or cancellation of third-party insurance coverage would increase our overall risk exposure as well as disrupt the management of our business operations. We maintain insurance coverage from third-party insurers as part of our overall risk management strategy and because some of our contracts require us to maintain specific insurance coverage limits. If any of our third- party insurers fail, suddenly cancel our coverage or otherwise are unable to provide us with adequate insurance coverage, then our overall risk exposure and our operational expenses would increase, and the management of our business operations would be disrupted. In addition, there can be no assurance that any of our existing insurance coverage will be renewable upon the expiration of the coverage period or that future coverage will be affordable at the required limits. Adverse judgments or settlements in legal disputes could result in materially adverse monetary damages or injunctive relief and damage our reputation. We are subject to, and may become a party to, a variety of litigation or other claims and suits that arise from time to time in the ordinary course of our business. For example, our performance under U.S. government contracts and compliance with the terms of those contracts and applicable laws and regulations are subject to continuous audit, review, and investigation by the U.S. government which may include such investigative techniques as subpoenas or civil investigative demands. The results of litigation and other legal proceedings, including the claims described under “Business—Legal Proceedings”, are inherently uncertain and adverse judgments or settlements in some or all of these legal disputes 33 may result in materially adverse monetary damages or injunctive relief against us. Additionally, our insurance policies may not protect us against potential liability due to various exclusions in the policies and self-insured retention amounts. Partially or completely uninsured claims, if successful and of significant magnitude, could have a material adverse effect on our business, financial condition and results of operations. Furthermore, any claims or litigation, even if fully indemnified or insured, could damage our reputation and make it more difficult to compete effectively or obtain adequate insurance in the future. Our business is subject to numerous legal and regulatory requirements and any violation of these requirements or any misconduct by our employees, subcontractors, agents or business partners could harm our business and reputation. In addition to government contract procurement laws and regulations, we are subject to numerous other federal, state and foreign legal requirements on matters as diverse as data privacy and protection, employment and labor relations, immigration, taxation, anti-corruption, import/export controls, trade restrictions, internal and disclosure control obligations, securities regulation and anti-competition. Compliance with diverse and changing legal requirements is costly, time-consuming and requires significant resources. Violations of one or more of these requirements in the conduct of our business could result in significant fines and other damages, criminal sanctions against us or our officers, prohibitions on doing business and damage to our reputation. Violations of these regulations or contractual obligations related to regulatory compliance in connection with the performance of customer contracts could also result in liability for significant monetary damages, fines and/or criminal prosecution, unfavorable publicity and other reputational damage, restrictions on our ability to compete for work and allegations by our customers that we have not performed our contractual obligations. Misconduct by our employees, subcontractors, agents or business partners could subject us to fines and penalties, restitution or other damages, loss of security clearance, loss of current and future customer contracts and suspension or debarment from contracting with federal, state or local government agencies, any of which could adversely affect our business, financial condition and results of operations. Such misconduct could include fraud or other improper activities such as falsifying time or other records, failure to comply with our policies and procedures or violations of applicable laws and regulations. Our services and operations sometimes involve handling or disposing of hazardous substances or dangerous materials, and we are subject to environmental requirements and risks which could result in significant costs, liabilities and obligations. Our operations are subject to stringent and complex federal, state and local laws and regulations governing the discharge of materials into the environment, the health and safety aspects of our operations, or otherwise relating to environmental protection. Some of our services and operations involve the handling or disposal of hazardous substances or dangerous materials, including explosive, chemical, biological, radiological or nuclear materials. These activities generally subject us to extensive foreign, federal, state and local environmental protection and health and safety laws and regulations, which, among other things, require us to incur costs to comply with these regulations and could impose liability on us for handling or disposing of hazardous substances or dangerous materials. Numerous governmental authorities, such as the U.S. Environmental Protection Agency, or the EPA, and analogous state agencies, have the power to enforce compliance with these laws and regulations and the permits issued under them. Such enforcement actions often involve difficult and costly compliance measures or corrective actions. Furthermore, failure to comply with these environmental protection and health and safety laws and regulations could result in civil, criminal, regulatory, administrative or contractual sanctions, including fines, penalties or suspension or debarment from contracting with the U.S. government, and could also result in investigations, the imposition of corrective action or remedial obligations, and the issuance of orders limiting or prohibiting some or all of our operations. In certain instances, citizen groups also have the ability to bring legal proceedings against us if we are not in compliance with environmental laws. In addition, claims for damages to persons or property, including natural resources, may result from the environmental, health and safety impacts of our operations. We, like other businesses, can never completely eliminate the risk of 34 contamination or injury from certain materials that we use in our business. If we have any violations of, or incur liabilities pursuant to, these laws or regulations, it may result in a material adverse effect on our business, financial condition or results of operations. Certain environmental laws impose strict liability (i.e., no showing of “fault” is required) as well as joint and several liability for costs required to remediate and restore sites where hazardous substances, hydrocarbons or solid wastes have been stored or released. We may be required to remediate contaminated properties currently or formerly owned or operated by us or facilities of third parties that received waste generated by our operations, regardless of whether such contamination resulted from the conduct of others or from the consequences of our own actions that were in compliance with all applicable laws at the time those actions were taken. We have limited, and potentially insufficient, insurance coverage for expenses and losses that may arise in connection with environmental contamination. Finally, in connection with certain acquisitions, we could acquire, or be required to provide indemnification against, environmental liabilities that could expose us to material losses. Our failure to meet contractual schedule requirements, meet a required performance standard, meet our internal contractual performance projections or otherwise perform adequately on a project could adversely affect our business, financial condition or results of operations. Under some of our contracts, we can incur liquidated or other damages if we do not achieve project completion by a scheduled date. In addition, our costs generally increase from schedule delays and/or could exceed our projections for a particular project. Project performance can be affected by a number of factors beyond our control, including unavoidable delays from governmental inaction, public opposition, inability to obtain financing, weather conditions, unavailability of vendor materials, changes in the project scope of services requested by our clients, industrial accidents, environmental hazards, labor disruptions and other factors. Any defects or errors, or failures to meet our clients’ expectations, in our projects or services could result in claims for damages against us and could adversely affect our reputation. Material performance problems for existing and future contracts could cause actual results of operations to differ from those anticipated by us and also could cause us to suffer damage to our reputation within our industries and client base. Failure to adequately protect, maintain, or enforce our rights in our intellectual property may adversely limit our competitive position. We rely upon a combination of nondisclosure agreements and other contractual arrangements, as well as copyright, trademark, patent and trade secret laws to protect our proprietary information. We also enter into proprietary information and intellectual property agreements with employees, which require them to disclose any inventions created during employment, to convey such rights to inventions to us, and to restrict any disclosure of proprietary information. Trade secrets are generally difficult to protect. Although our employees are subject to confidentiality obligations, this protection may be inadequate to deter or prevent misappropriation of our confidential information and/or the infringement of our patents and copyrights. Further, we may be unable to detect unauthorized use of our intellectual property or otherwise take appropriate steps to enforce our rights. Failure to adequately protect, maintain, or enforce our intellectual property rights may adversely limit our competitive position. Assertions by third parties of infringement, misappropriation or other violations by us of their intellectual property rights could result in significant costs and substantially harm our business, financial condition and operation results. In recent years, there has been significant litigation involving intellectual property rights in technology industries. We may face from time to time, allegations that we or a supplier or customer have violated the rights of third parties, including patent, trademark, and other intellectual property rights. If, with respect to any claim 35 against us for violation of third-party intellectual property rights, we are unable to prevail in the litigation or retain or obtain sufficient rights or develop non-infringing intellectual property or otherwise alter our business practices on a timely or cost-efficient basis, our business, financial condition or results of operations may be adversely affected. Any infringement, misappropriation or related claims, whether or not meritorious, are time consuming, divert technical and management personnel, and are costly to resolve. As a result of any such dispute, we may have to develop non-infringing technology, pay damages, enter into royalty or licensing agreements, cease utilizing products or services, or take other actions to resolve the claims. These actions, if required, may be costly or unavailable on terms acceptable to us. Risks Related to International Operations Our operations outside the United States expose us to legal, political and economic risks in different countries as well as currency exchange rate fluctuations that could harm our business and financial results. Revenue attributable to our services provided outside of the United States as a percentage of our total revenue was 24.5% in 2020, 24.8% in 2019 and 29.8% in 2018. There are risks inherent in doing business internationally, including: • • • • • • • • • • • imposition of governmental controls and changes in laws, regulations or policies; political and economic instability, such as in the Middle East; civil unrest, acts of terrorism, force majeure, war, or other armed conflict; greater physical security risks; changes in U.S. and other national government trade policies affecting the markets for our services; changes in regulatory practices, tariffs and taxes; potential non-compliance with a wide variety of laws and regulations, including anti-corruption, U.S. export controls and economic and trade sanctions, and anti-boycott laws and similar non-U.S. laws and regulations; changes in labor conditions; logistical and communication challenges; currency exchange rate fluctuations, devaluations and other conversion restrictions; and health and safety concerns, including those related to the COVID-19 pandemic and other potential epidemics. Any of these factors could have a material adverse effect on our business, financial condition or results of operations. We have operations in the Middle East and neighboring regions, and these regions may experience turmoil that may impact our current projects, future business and financial stability. We currently have operations in the Middle East, including in Oman, Qatar, Saudi Arabia and the United Arab Emirates. These countries experience frequent political turmoil such as the tensions among Qatar and several of its neighbors, including Saudi Arabia and the United Arab Emirates. This uncertainty may affect our ability to continue our projects in these regions due to lack of resources, local support, and safety for our workers. If we are unable to finish these projects, it is likely that our finances will be impacted. Furthermore, we may experience liability regarding our employees and their safety and security in these locations. We also may 36 incur material costs to maintain the safety of our personnel. Despite these precautions, the safety of our personnel in these locations may continue to be at risk. Acts of terrorism and threats of armed conflicts in or around various areas in which we operate could limit or disrupt markets and our operations, including disruptions resulting from the evacuation of personnel, cancellation of contracts, or the loss of key employees, contractors or assets. We operate in many different jurisdictions and we could be adversely affected by violations of the U.S. Foreign Corrupt Practices Act and similar worldwide anti-corruption laws. The FCPA and similar worldwide anti-corruption laws, including the U.K. Bribery Act of 2010, generally prohibit companies and their intermediaries from making improper payments to non-U.S. officials for the purpose of obtaining or retaining business. Our internal policies mandate compliance with these anti-corruption laws, including the requirements to maintain accurate information and internal controls which may fall within the purview of the FCPA, its books and records provisions or its anti-bribery provisions. We operate in many parts of the world that have experienced governmental corruption to some degree; and, in some circumstances, strict compliance with anticorruption laws may conflict with local customs and practices. Despite our training and compliance programs, we cannot assure that our internal control policies and procedures always will protect us from reckless or criminal acts committed by our employees or agents. In addition, from time to time, government investigations of corruption in industries we operate in may affect us and our peers. Violations of these laws, or allegations of such violations, could disrupt our business and result in a material adverse effect on our business, financial condition or results of operations. Risks Related to Debt and Backlog We may not realize the full value of our backlog, which may result in lower than expected revenue. As of December 31, 2020, our total backlog was $8.1 billion, of which $4.0 billion was funded. Our backlog includes orders under contracts that can extend for several years, and in some cases, contracts that extend for more than 10 to 15 years. We historically have not realized all of the revenue included in our total backlog, and we may not realize all of the revenue included in our total backlog in the future. There is a somewhat higher degree of risk in this regard with respect to unfunded backlog and backlog related to unexercised options years and IDIQ contracts for which task orders have not yet been issued. In addition, there can be no assurance that our backlog will result in actual revenue in any particular period. This is because the actual receipt, timing and amount of revenue under contracts included in backlog are subject to various contingencies, including congressional appropriations, many of which are beyond our control. In particular, delays in the completion of the U.S. government’s budgeting process and the use of continuing resolutions could adversely affect our ability to timely recognize revenue under our contracts included in backlog. Furthermore, the actual receipt of revenue from contracts included in backlog may never occur or may be delayed because: a program schedule could change or the program could be canceled; a contract’s funding or scope could be reduced, modified, delayed or terminated early, including as a result of a lack of appropriated funds or as a result of cost cutting initiatives and other efforts to reduce government spending; in the case of funded backlog, the period of performance for the contract has expired; in the case of unfunded backlog, funding may not be available; in the case of backlog related to unexercised option years, the contract option is not yet exercised or may ever be exercised; and, in the case of backlog related to IDIQ contracts where task orders have not been issued, no further task orders may be issued. In addition, headcount growth is the primary means by which we are able to achieve revenue growth. Any inability to hire additional appropriately qualified personnel or failure to timely and effectively deploy such additional personnel against funded backlog could negatively affect our ability to grow our revenue. We may also not recognize revenue on funded backlog due to, among other reasons, the tardy submissions of invoices by our subcontractors and the expiration of the relevant appropriated funding in accordance with a predetermined expiration date such as the end of the U.S. government’s fiscal year. The amount of our funded backlog is also subject to change, due to, among other factors: changes in appropriations that reflect changes in government policies or priorities resulting from various military, political, economic or international developments; changes in the use of government contracting vehicles, and the provisions therein used to procure our services; and 37 adjustments to the scope of services under, or cancellation of contracts, by the applicable government at any time. Furthermore, even if our backlog results in revenue, the contracts may not be profitable. If we cannot collect our receivables or if payment is delayed, our business may be adversely affected by our inability to generate cash flow, provide working capital or continue our business operations. As of December 31, 2020, our accounts receivable, net was $698.6 million. We depend on the timely collection of our receivables to generate cash flow, provide working capital and continue our business operations. If our customers fail to pay or delay the payment of invoices for any reason, our business and financial condition may be materially and adversely affected. Our customers have in the past and may in the future delay or fail to pay invoices for a number of reasons, including lack of appropriated funds, lack of an approved budget or as a result of audit findings by government regulatory agencies. We also experience longer payment cycles in the Middle East. We cannot assure you that we will collect all our accounts receivable in excess of our allowance for doubtful accounts in a timely manner, which would impact our cash flows. The agreements governing our debt contain a number of restrictive covenants which may limit our ability to finance future operations, acquisitions or capital needs or engage in other business activities that may be in our interest. As of December 31, 2020, our total indebtedness was $590 million. Our Credit Agreement and the agreements governing our Senior Notes contain a number of covenants that impose operating and other restrictions on us and our subsidiaries. Such restrictions affect or will affect, and in many respects limit or prohibit our ability and the ability of our subsidiaries to, among other things: • • • • incur additional indebtedness; create liens; pay dividends and make other distributions in respect of our equity securities; redeem our equity securities; • make loans, advances, investments or other restricted payments; • • • • • sell assets or receivables; engage in certain business activities; amend our ESOP’s plan documents; enter into transactions with affiliates; and effect mergers or consolidations. In addition, our Credit Agreement also requires us to comply with certain financial ratio covenants, including a debt leverage ratio and a fixed charge coverage ratio. Our ability to comply with these ratios may be affected by events beyond our control. These restrictions could limit our ability to plan for or react to market or economic conditions or meet capital needs or otherwise restrict our activities or business plans, and could adversely affect our ability to finance our operations, acquisitions, investments or strategic alliances or other capital needs or to engage in other business activities that would be in our interest. A breach of any of these covenants or our inability to comply with the required financial ratios could result in a default under our debt instruments. If an event of default occurs, our creditors could elect to: • declare all borrowings outstanding, together with accrued and unpaid interest, to be immediately due and payable; 38 • • require us to apply all of our available cash to repay the borrowings; or prevent us from making debt service payments on some of our borrowings. If we were unable to repay or otherwise refinance these borrowings when due, the lenders under our Credit Agreement could demand payment from subsidiary guarantors, as provided under our Credit Agreement. These guarantors constitute substantially all of our domestic, wholly owned subsidiaries’ assets. Prior to our initial public offering, we were 100% owned by the ESOP, which is a retirement plan that is intended to be qualified under the Code. If the ESOP failed to meet the requirements of a tax qualified retirement plan, we could be subject to substantial penalties. The ESOP is a defined contribution retirement plan subject to the requirements of the Code and ERISA. The ESOP has received a determination letter, dated January 31, 2012, from the Internal Revenue Service (IRS) that it meets the requirements of a tax qualified retirement plan in form and we endeavor to maintain and administer the ESOP in compliance with all requirements of the Code and ERISA. However, the rules regarding tax qualified plans, and especially ESOPs, are complex and change frequently. Accordingly, it is possible that the ESOP may not have been administered in full compliance with all applicable rules under the Code or ERISA at all times. If the ESOP were determined not to be in material compliance with the Code or ERISA, then the ESOP could lose its tax qualified status and we could be subject to substantial penalties under the Code and ERISA which could have a material adverse effect on our business, financial condition or results of operations. Additionally, loss of the ESOP’s tax-qualified status would adversely impact our prior treatment as an S Corporation. Risks Related to our Employees A failure to attract, train and retain skilled employees and our senior management team would adversely affect our ability to execute our strategy and may disrupt our operations. Our business relies heavily upon the expertise and services of our employees. Our continued success depends on our ability to recruit and retain highly trained and skilled engineering, technical and professional personnel. Competition for skilled personnel is intense and competitors aggressively recruit key employees. In addition, many U.S. government programs require contractors to have security clearances. Depending on the level of required clearance, security clearances can be difficult and time-consuming to obtain and personnel with security clearances are in great demand. Particularly in highly specialized areas, it has become more difficult to retain employees and meet all of our needs for employees in a timely manner, which may affect our growth in the current and future fiscal years. Although we intend to continue to devote significant resources to recruiting, training and retaining qualified employees, we may not be able to attract, effectively train and retain these employees. Any failure to do so could impair our ability to efficiently perform our contractual obligations, timely meet our customers’ needs and ultimately win new business, all of which could adversely affect our business, financial condition and results of operations. We believe that our success also depends on the continued employment of a highly qualified and experienced senior management team and that team’s ability to retain existing business and generate new business. The loss of key personnel in critical functions could lead to lack of business continuity or disruptions in our business until we are able to hire and train replacement personnel. We may lose one or more members of our senior management team or fail to develop new leaders, which could cause a disruption in the management of our business. We believe that the future success of our business and our ability to operate profitably depends on the continued contributions of the members of our senior management and the continued development of new 39 members of senior management. We rely on our senior management to generate business and execute programs successfully. In addition, the relationships and reputation that many members of our senior management team have established and maintain with our clients are important to our business and our ability to identify new business opportunities. We do not have any employment agreements providing for a specific term of employment with any members of our senior management. The loss of any member of our senior management or our failure to continue to develop new members could impair our ability to identify and secure new contracts, to maintain good client relations, and to otherwise manage our business, and could have a material adverse effect on our business, financial condition and results of operations. Negotiations with labor unions and possible work actions could divert management attention and disrupt operations. In addition, new collective bargaining agreements or amendments to existing agreements could increase our labor costs and operating expenses. We have entered into twenty-four union labor or collective bargaining agreements as of December 31, 2020. The outcome of any future negotiations relating to union representation or collective bargaining agreements for these or other employees in the future may not be favorable to us. We may reach agreements in collective bargaining that increase our operating expenses and lower our net income as a result of higher wages or benefit expenses. In addition, negotiations with unions could divert management attention and disrupt operations, which may adversely affect our results of operations. If we are unable to negotiate acceptable collective bargaining agreements, we may have to address the threat of union-initiated work actions, including strikes. Depending on the nature of the threat or the type and duration of any work action, these actions could disrupt our operations and adversely affect our operating results. Many of our field project sites and facilities are inherently dangerous workplaces. Failure to manage our field project sites and facilities safely could result in environmental disasters, employee deaths or injuries, reduced profitability, the loss of projects or clients and possible exposure to litigation. Our field project sites and facilities, particularly in our Critical Infrastructure business, often put our employees and others in close proximity with mechanized equipment, moving vehicles, chemical and manufacturing processes, and highly regulated materials. On some field project sites and in some of our facilities, we may be responsible for safety and, accordingly, we have an obligation to implement effective safety procedures. If these procedures are not appropriately implemented or are ineffective, our employees could be injured or killed, and we could be exposed to possible litigation. As a result, our failure to maintain adequate safety standards and equipment could result in reduced profitability or the loss of projects or clients and could have a material adverse impact on our business, financial condition, and results of operations. 40 Risk Related to Our Common Stock If we are unable to implement and maintain effective internal control over financial reporting in the future, investors may lose confidence in the accuracy and completeness of our financial reports and the market price of our common stock may be negatively affected. As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in such internal control. In addition, beginning with our second annual report on Form 10-K, we will be required to furnish a report by management on the effectiveness of our internal control over financial reporting, pursuant to Section 404 of the Sarbanes-Oxley Act. At such time, our independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied with the level at which our internal control over financial reporting is documented, designed or operating. The process of designing, implementing and testing the internal control over financial reporting required to comply with this obligation is time-consuming, costly and complicated. If we identify material weaknesses in our internal control over financial reporting, or if we are unable to comply with the requirements of Section 404 of the Sarbanes-Oxley Act in a timely manner or to assert that our internal control over financial reporting is effective, or if our independent registered public accounting firm is unable to express an opinion as to the effectiveness of our internal control over financial reporting, investors may lose confidence in the accuracy and completeness of our financial reports, the market price of our common stock could be negatively affected, and we could become subject to investigations by our stock exchange, the SEC or other regulatory authorities, which could require additional financial and management resources. If our stock price fluctuates, you could lose a significant part of your investment. The market price of our stock may be influenced by many factors, some of which are beyond our control, including the following: • • • • • • the opinions and estimates of any securities analysts who publish research about us; announcements by us or our competitors of significant contracts, acquisitions or capital commitments; variations in quarterly operating results; changes in general economic or market conditions or trends in our industry or the economy as a whole; future sales of our common stock; and investor perception of us and the industries we operate in. As a result of these factors, investors in our common stock may not be able to resell their shares at or above the initial purchase price. These broad market and industry factors may materially reduce the market price of our common stock, regardless of our operating performance. In addition, the stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies. In the past, stockholders have instituted securities class action litigation following periods of market volatility. If we were involved in securities litigation, we could incur substantial costs and our resources, and the attention of management could be diverted from our business. Our operating results and share price may be volatile, and the market price of our common stock may drop. Our quarterly operating results are likely to fluctuate in the future as a publicly traded company. In addition, securities markets worldwide have experienced, and are likely to continue to experience, significant price and volume fluctuations. This market volatility, as well as general economic, market or political conditions, could 41 subject the market price of our shares to wide price fluctuations regardless of our operating performance. Our operating results and the trading price of our shares may fluctuate in response to various factors, including: • market conditions in the broader stock market; • • • • • • • • • • • • • • • • • • • actual or anticipated fluctuations in our quarterly financial and operating results; introduction of new products or services by us or our competitors; changes in our awards, backlog and book-to-bill ratios in a given period; issuance of new or changed securities analysts’ reports or recommendations; results of operations that vary from expectations of securities analysis and investors; guidance, if any, that we provide to the public, any changes in this guidance or our failure to meet this guidance; strategic actions by us or our competitors; announcement by us, our competitors or our acquisition targets; sales, or anticipated sales, of large blocks of our stock; additions or departures of key personnel; regulatory, legal or political developments; public response to press releases or other public announcements by us or third parties, including our filings with the SEC; litigation and governmental investigations; seasonality associated with U.S. federal, state, regional and local government funding and spending; changing economic conditions; changes in accounting principles; default under agreements governing our indebtedness; exchange rate fluctuations; and other events or factors, including those from natural disasters, war, actors of terrorism or responses to these events and pandemics, such as the COVID-19 pandemic. These and other factors, many of which are beyond our control, may cause our operating results and the market price and demand for our shares to fluctuate substantially. While we believe that operating results for any particular quarter are not necessarily a meaningful indication of future results, fluctuations in our quarterly operating results could limit or prevent investors from readily selling their shares and may otherwise negatively affect the market price and liquidity of our shares. In addition, in the past, when the market price of a stock has been volatile, holders of that stock have sometimes instituted securities class action litigation against the company that issued the stock. If any of our stockholders brought a lawsuit against us, we could incur substantial costs defending the lawsuit. Such a lawsuit could also divert the time and attention of our management from our business, which could significantly harm our profitability and reputation. Sales of outstanding shares of our common stock into the market in the future could cause the market price of our common stock to drop significantly, even if our business is doing well. At December 31, 2020, we had 146,609,288 shares of our common stock issued and 102,360,662 outstanding. Of these shares, 76,641,312 shares are owned by the ESOP, 25,719,350 shares are publicly owned, and 44,248,626 shares are Treasury stock. We are party to a registration rights agreement with the ESOP Trustee, 42 providing the ESOP with certain demand registration rights related to shares held by the ESOP in the event the ESOP Trustee determines in good faith, in exercising its fiduciary duties under ERISA, that the ESOP is required to sell its shares, which we believe is only likely to occur if our business, financial condition or results of operations have materially and adversely deteriorated. Qualifying ESOP participants have the right to receive distributions of shares of our common stock from the ESOP and can sell such shares in the market. As of December 31, 2020, there were 76,641,312 shares of common stock held in the ESOP. Shares held in the ESOP are eligible for sale in the public market, subject to applicable Rule 144 limitations, vesting restrictions and any applicable market standoff agreements and lock-up agreements. Participants are generally entitled to distributions from the ESOP only following termination of employment or upon death and in order to diversify their accounts upon attaining a specified age and completing a specified number of years of service. As previously noted in the section of Part 1, Item 1 entitled “Employee Stock Ownership Plan”, in December 2020, the board of directors approved an amendment to the Employee Stock Ownership Plan to provide more flexible diversification rights for participants, and in January 2021, the board of directors approved the modification of the thresholds for distributions to participants in the ESOP effective March 1, 2021. ESOP distributions are made in the form of shares of our common stock (other than distributions in respect of fractional shares, which will be made in cash). Upon receiving a distribution of our common stock from the ESOP, a participant will be able to sell such shares in the market. As a result, we cannot predict the effect, if any, that these distributions and the corresponding sales of shares by the participants may have on the market price of our common stock. Distribution of substantial amounts of our common stock to participants may cause the market price of our common stock to decline. The issuance of additional stock, not reserved for issuance under our equity incentive plans or otherwise, will dilute all other stockholdings. We have an aggregate of 853,390,712 shares of common stock authorized but not outstanding and not reserved for issuance under our 2020 Plan, under our existing Incentive Plans or otherwise. We may issue all of these shares without any action or approval by our stockholders. The issuance of additional shares could be dilutive to existing holders. We historically have made annual contributions of our common stock to the ESOP. We made contributions of 1,522,381 shares in fiscal 2020, 1,345,198 shares in fiscal 2019, and 1,874,988 shares in fiscal 2018 of our common stock to the ESOP and intend to continue to make annual contributions in shares of our common stock to the ESOP. In fiscal 2020, 2019 and 2018, we made annual contributions to the ESOP in shares of our common stock in the amount of 8% of the participants’ cash compensation for the applicable year (net of shares forfeited by participants in the applicable year). For future fiscal years, the annual contribution to the ESOP shall be in amounts as determined by the board of directors. Your ability to influence corporate matters may be limited because the ESOP beneficially owns a majority of our stock and therefore our participants, voting the shares allocated to them under the ESOP, or the ESOP Trustee, who will have the right to vote shares for which no voting instructions are provided by employees, could have substantial control over us. Our common stock has one vote per share. The ESOP beneficially owns approximately 75% of our outstanding common stock. Under the terms of the ESOP, each participant has the ability to direct the ESOP Trustee on the voting of the shares allocated to his or her account under the ESOP. However, the ESOP Trustee will vote any shares that a participant does not direct the voting, or any shares that are held by the ESOP which are not allocated to participants’ accounts. As such, the ESOP Trustee may be able to exercise a greater influence than otherwise over matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions. 43 The purpose of the ESOP is to provide retirement income to employees and their beneficiaries. Accordingly, the interests of the ESOP and the ESOP participants may be contrary to yours as an outside investor. ERISA sets forth certain fiduciary requirements that require an ERISA fiduciary, like the ESOP Trustee, to act solely in the interests of plan participants and their beneficiaries for the purpose of providing retirement benefits. The Department of Labor, which is the agency with the authority to interpret and enforce the fiduciary sections of ERISA, has indicated in its interpretative guidance that voting is an ERISA fiduciary act. The ESOP Trustee’s fiduciary duties under ERISA to the ESOP and its participants may cause the ESOP Trustee to override participants’ voting directions to the extent that following such directions would violate ERISA. In such case, the ESOP Trustee will be able to exercise voting control over all of the ESOP’s shares. Further, the interests of the minority stockholders may not be aligned with those of the ESOP as the majority stockholder, because the ESOP Trustee is required under ERISA to act in the best interest of the ESOP participants and beneficiaries, this may present a conflict. As a result, the concentration of ownership in our company by the ESOP could delay or prevent a change in control of our company or otherwise discourage a potential acquirer from attempting to obtain control of our company, which in turn could reduce the price of our common stock. We are a “controlled company” within the meaning of the New York Stock Exchange listing standards and, as a result, qualify for exemptions from certain corporate governance requirements. You may not have the same protections afforded to stockholders of companies that are subject to such requirements. The ESOP holds common stock representing approximately 75% of the voting power of our common stock as of December 31, 2020. As a result, we are considered a “controlled company” for the purposes of New York Stock Exchange (“NYSE”) rules and corporate governance standards. As a controlled company, we are exempt from certain NYSE corporate governance requirements, including those that would otherwise require our board of directors to have a majority of independent directors and require that we either establish compensation and nominating and corporate governance board committees, each comprised entirely of independent directors, or otherwise ensure that the compensation of our executive officers and nominees for directors are determined or recommended to the board of directors by the independent members of the board of directors. While we intend to have a majority of independent directors, and our compensation and nominating and corporate governance committees to consist entirely of independent directors, we may decide at a later time to rely on one of the “controlled company” exemptions. Accordingly, our common stock may not have the same protections afforded to stockholders of companies that are subject to all of the NYSE corporate governance requirements. Our ability to raise capital in the future may be limited, which could limit our business plan or adversely affect your investment. Our business and strategic plans may consume resources faster than we anticipate. In the future, we may need to raise additional funds through the issuance of new equity securities, debt or a combination of both. However, any decline in the market price of our common stock could impair our ability to raise capital. Separately, additional financing may not be available on favorable terms, or at all. If adequate funds are not available on acceptable terms, we may be unable to fund our operations or new investments. If we issue new debt securities, the debt holders would have rights senior to common stockholders to make claims on our assets, and the terms of any debt could restrict our operations, including our ability to pay dividends on our common stock. If we issue additional equity securities, existing stockholders will experience dilution, and the new equity securities could have rights senior to those of our common stock. Because our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. Thus, our stockholders bear the risk of our future securities offerings reducing the market price of our common stock and diluting their interest. 44 Anti-takeover provisions in our organizational documents could delay a change in management and limit our share price. Provisions of our certificate of incorporation and bylaws could make it more difficult for a third party to acquire control of us even if such a change in control would increase the value of our common stock and prevent attempts by our stockholders to replace or remove our current board of directors or management. We have a number of anti-takeover devices that could hinder takeover attempts and could reduce the market value of our common stock or prevent sale at a premium. Our anti-takeover provisions: • • • • • • • • • permit the board of directors to establish the number of directors and fill any vacancies and newly created directorships; provide that our board of directors is classified into three classes with staggered, three-year terms and that directors may only be removed for cause; include blank-check preferred stock, the preference, rights and other terms of which may be set by the board of directors and could delay or prevent a transaction or a change in control that might involve a premium price for our common stock or otherwise benefit our stockholders; eliminate the ability of our stockholders to call special meetings of stockholders; specify that special meetings of our stockholders can be called only by our board of directors or a board committee authorized with the power to call such meetings; prohibit stockholder action by written consent, which requires all stockholder actions to be taken at a meeting of our stockholders; provide that vacancies on our board of directors may be filled only by a majority of directors then in office, even though less than a quorum; prohibit cumulative voting in the election of directors; and establish advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted upon by stockholders at annual stockholders’ meetings. In addition, as a Delaware corporation, we are subject to Section 203 of the Delaware General Corporation Law, or the DGCL. These provisions may prohibit large stockholders, in particular those owning 15% or more of our outstanding voting stock, from merging or combining with us for a period of time. Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees. Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for the following civil actions: • • • • any derivative action or proceeding brought on our behalf; any action asserting a claim of breach of a fiduciary duty by any of our directors, officers, employees or agents or our stockholders; any action asserting a claim arising pursuant to any provision of the DGCL or our certificate of incorporation or bylaws or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware; or any action asserting a claim governed by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that the stockholder finds favorable for disputes with us or our directors, officers or other employees, which may 45 discourage such lawsuits against us and our directors, officers and other employees. Alternatively, if a court were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could have a material adverse effect on our business, financial condition or results of operations. We do not expect to declare any dividends in the foreseeable future. We do not anticipate declaring any cash dividends to holders of our common stock in the foreseeable future. Any determination to pay dividends in the future will be at the discretion of our board of directors and will depend upon results of operations, financial condition, any contractual restrictions, our indebtedness, restrictions imposed by applicable law and other factors our board of directors deems relevant. Consequently, investors may need to sell all or part of their holdings of our common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investment. Investors seeking cash dividends should not purchase our common stock. If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline. The trading market for our common stock depends, in part, on the research and reports that securities or industry analysts publish about us or our business. If an analyst who covers us downgrades our common stock or publishes inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, demand for our common stock could decrease, which could cause our stock price and trading volume to decline. Item 1B. Unresolved Staff Comments. None. Item 2. Properties. Our headquarters are located in Centreville, Virginia. As of December 31, 2020, we leased 238 commercial facilities (including our headquarters) with an aggregate of approximately 3.0 million square feet of space across 36 U.S. states and 16 countries used in connection with the various services rendered to our customers. Additionally, we operate at several customer-accredited Sensitive Compartmented Information Facilities, which are highly specialized, secure facilities used to perform classified work for the United States intelligence community. We also have employees working at customer sites throughout the U.S. and in other countries. We believe our facilities are adequate for our current and presently foreseeable needs. Item 3. Legal Proceedings. Our performance under our contracts and our compliance with the terms of those contracts and applicable laws and regulations are subject to continuous audit, review and investigation by our customers, including the U.S. federal government. In addition, we are from time to time involved in legal proceedings and investigations arising in the ordinary course of business, including those relating to employment matters, relationships with clients and contractors, intellectual property disputes, environmental matters and other business matters. Although the outcome of any such matter is inherently uncertain and may be materially adverse, based on current information, except as noted below, we believe there are no pending lawsuits or claims that may have a material adverse effect on our business, financial condition or results of operations. On or about March 1, 2017, the Peninsula Corridor Joint Powers Board, or the JPB, filed a lawsuit against Parsons Transportation Group, Inc., or PTG, in the Superior Court of California, County of San Mateo, in 46 connection with a positive train control project on which PTG was engaged prior to termination of its contract by the JPB. PTG had previously filed a lawsuit against the JPB for breach of contract and wrongful termination. The JPB seeks damages in excess of $100.0 million, which we are currently disputing. In addition to filing our complaint for breach of contract and wrongful termination, we have denied the allegations raised by the JPB and, accordingly, filed affirmative defenses. We are currently defending against the JPB’s claims and the parties are still engaged in discovery. We also have a professional liability insurance policy to the extent the JPB proves any errors or omissions occurred. At this time, it is too soon to determine the outcome of the litigation or assess the potential range of exposure, if any. We have also filed a third-party claim against a subcontractor for indemnification in connection with this matter. In September 2015, a former Parsons employee filed an action in the United States District Court for the Northern District of Alabama against us as a qui tam relator on behalf of the United States (the “Relator”) alleging violation of the False Claims Act. The plaintiff alleges that, as a result of these actions, the United States paid in excess of $1 million per month between February and September 2006 that it should have paid to another contractor, plus $2.9 million to acquire vehicles for the contractor defendant to perform its security services. The lawsuit sought (i) that we cease and desist from violating the False Claims Act, (ii) monetary damages equal to three times the amount of damages that the United States has sustained because of our alleged violations, plus a civil penalty of not less than $5,500 and not more than $11,000 for each alleged violation of the False Claims Act, (iii) monetary damages equal to the maximum amount allowed pursuant to §3730(d) of the False Claims Act, and (iv) Relator’s costs for this action, including recovery of attorneys’ fees and costs incurred in the lawsuit. The United States government did not intervene in this matter as it is allowed to do so under the statute. We filed a motion to dismiss the lawsuit on the grounds that the Relator did not meet the applicable statute of limitations. The District Court granted our motion to dismiss. The Relator’s attorney appealed the decision to the United States Court of Appeals of the Eleventh Circuit, which ultimately ruled in favor of the Relator, and we petitioned the United States Supreme Court to review the decision. The Supreme Court upheld the Appellate Court ruling and remanded the case to the District Court. The parties are engaged in limited discovery and Parsons has filed a renewed motion to dismiss the case. On or about October 4, 2019, LBH Engineers, LLC (“LBH”) filed a lawsuit against Parsons, PTG, and various other parties in the US District Court of for the Northern District of Georgia, in connection with an alleged infringement of LBH’s patent. LBH seeks damages and costs incurred by LBH, a post-judgment royalty, treble damages if the infringement is found to be willful, among other damages, which the Company and the other defendants are currently disputing. At this time, the Company is unable to determine the probability of the outcome of the litigation or determine a potential range of loss, if any. Item 4. Mine Safety Disclosures. Not Applicable. 47 PART II Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities. On May 8, 2019, the Company consummated its initial public offering (“IPO”) whereby the Company sold 18,518,500 shares of common stock for $27.00 per share. The underwriters exercised their share option on May 14, 2019 to purchase an additional 2,777,775 shares at the share price of $25.515 which was the IPO share price of $27.00 less the underwriting discount of $1.485 per share. Our common stock is listed on the NYSE under the ticker symbol “PSN”. The following table presents the ranges of high and low sales prices of our common stock quoted on the NYSE for each quarter since the IPO on May 8, 2019.

On April 3, 2019, the board of directors of the Company declared a cash dividend to the Company’s sole existing shareholder at that time, the ESOP, in the amount of $2.00 per share, or $52.1 million in the aggregate (the “IPO Dividend”). The IPO Dividend was paid on May 10, 2019. On April 15, 2019, the board of directors of the Company declared a common stock dividend in a ratio of two shares of common stock for every one share of common stock then held by the Company’s shareholder (the “Stock Dividend”). The record date of the Stock Dividend was May 7, 2019, the day immediately prior to the consummation of the Company’s IPO on May 8, 2019, and the payment date of the Stock Dividend was May 8, 2019. Purchasers of the Company’s common stock in the Company’s public offering were not entitled to receive any portion of the Stock Dividend. Other than the IPO Dividend and the Stock Dividend discussed above, we currently do not intend to declare or pay any cash dividends in the foreseeable future. Any further determination to pay dividends on our capital stock will be at the discretion of our board of directors, subject to applicable laws, and will depend on our financial condition, results of operations, capital requirements, restrictions under our Senior Notes issued in a private placement in 2014, or the Convertible Senior Notes, and Credit Agreement, and other factors that our board of directors considers relevant. According to the records of our transfer agent, there were four shareholders of record as of February 12, 2021. The following graph compares the cumulative total return, from the IPO date through December 31, 2020, to shareholders of Parsons Corporation common stock relative to the cumulative total returns of the Russell 2000 Index and the Standard and Poor’s IT Consulting & Other Services Index. The graph assumes that the value of the investment in our common stock, the index, and the peer group (including reinvestment of dividends) was $100 on May 8, 2019 and tracks it through December 31, 2020.

(e) Reflects costs associated with and related to our corporate restructuring initiatives. (f) Includes a combination of gain/loss related to sale of fixed assets, software implementation costs, and other individually insignificant items that are non-recurring in nature. Adjusted EBITDA is a supplemental measure of our operating performance included in this Annual Report on Form 10-K because it is used by management and our board of directors to assess our financial performance both on a segment and on a consolidated basis. We discuss Adjusted EBITDA because our management uses this measure for business planning purposes, including to manage the business against internal projected results of operations and to measure the performance of the business generally. Adjusted EBITDA is frequently used by analysts, investors and other interested parties to evaluate companies in our industry. Adjusted EBITDA is not a U.S. GAAP measure of our financial performance or liquidity and should not be considered as an alternative to net income as a measure of financial performance or cash flows from operations as measures of liquidity, or any other performance measure derived in accordance with U.S. GAAP. We define Adjusted EBITDA as net income attributable to Parsons Corporation, adjusted to include net income attributable to noncontrolling interests and to exclude interest expense (net of interest income), provision for income taxes, depreciation and amortization and certain other items that we do not consider in our evaluation of ongoing operating performance. These other items include, among other things, impairment of goodwill, intangible and other assets, interest and other expenses recognized on litigation matters, amortization of deferred gain resulting from sale-leaseback transactions, expenses incurred in connection with acquisitions and other non-recurring transaction costs, equity-based compensation, and expenses related to our corporate restructuring initiatives. Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items. Additionally, Adjusted EBITDA is not intended to be a measure of free cash flow for management’s discretionary use, as it does not reflect tax payments, debt service requirements, capital expenditures and certain other cash costs that may recur in the future, including, among other things, cash requirements for working capital needs and cash costs to replace assets being depreciated and amortized. Management compensates for these limitations by relying on our U.S. GAAP results in addition to using Adjusted EBITDA supplementally. Our measure of Adjusted EBITDA is not necessarily comparable to similarly titled captions of other companies due to different methods of calculation. The following table shows Adjusted EBITDA attributable to Parsons Corporation for each of our reportable segments and Adjusted EBITDA attributable to noncontrolling interests: (U.S. dollars in thousands) Federal Solutions Adjusted EBITDA Fiscal Year Ended December 31, 2020 December 31, 2019 December 31, 2018 attributable to Parsons Corporation . . . . . . . . $167,340 $169,100 $121,986 Critical Infrastructure Adjusted EBITDA attributable to Parsons Corporation . . . . . . . . 154,528 138,851 106,851 Adjusted EBITDA attributable to noncontrolling interests . . . . . . . . . . . . . . . . . 20,753 17,096 17,407 Total Adjusted EBITDA . . . . . . . . . . . . . . $342,621 $325,047 $246,244 See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Segment Results,“ and “Note 21—Segments Information” in the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for further discussion regarding our segment Adjusted EBITDA attributable to Parsons Corporation. 52 Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. The following discussion and analysis is intended to help investors understand our business, financial condition, results of operations, liquidity and capital resources. You should read this discussion together with our consolidated financial statements and related notes thereto included elsewhere in this Annual Report on Form 10-K. The statements in this discussion regarding industry outlook, our expectations regarding our future performance, liquidity and capital resources and other non-historical statements in this discussion are forward- looking statements. These forward-looking statements are subject to numerous risks and uncertainties, including, but not limited to, the risks and uncertainties described in “Risk Factors” and “Special Note Regarding Forward-Looking Statements.” Actual results may differ materially from those contained in any forward-looking statements. COVID-19 Pandemic In response to the COVID-19 pandemic, the Company has taken certain actions to continue to execute under our contracts with customers and allow our people to work safely. A substantial majority of our workforce transitioned to work-from-home status during the latter part of the quarter ended March 31, 2020, and these practices remain in effect as of the date of this filing. To date, we have experienced no material disruption in our work as a consequence of these changes in our work practices. The Company has experienced an impact in the volume of work in both the Federal Solutions and Critical Infrastructure segments where customers have restricted access to certain project sites. We have not seen any substantive cancellations of previously awarded contracts. In the Federal Solutions segment, we have had some existing contracts extended. We continue to see several potential contract awards pushed out to a future date. The Company is receiving limited benefits associated with the CARES Act related to its work on certain US national security projects; however, the curtailment of work under these projects and the CARES Act benefits are not likely to have a material impact on our financial condition or results of operations. The reimbursement period for Section 3610 of the CARES Act extends until March 31, 2021. The Company has provided additional disclosure around liquidity and capital resources which can be found in the “Liquidity and Capital Resources” section in Management’s Discussion and Analysis of Financial Condition and Results of Operations in this Form 10-K. The Company anticipates substantially all of the Company’s subcontractors and material suppliers will be able to fulfill their contractual obligations and we do not expect a material impact from non-performance. The ultimate impact from the COVID-19 pandemic is difficult to predict. While many uncertainties exist, we currently anticipate no material change in our financial condition or results of operations 53 Overview We are a leading innovative technology provider in the global defense, intelligence and critical infrastructure markets. We provide software and hardware products, technical services and integrated solutions to support our customers’ missions. We have developed significant expertise and differentiated capabilities in key areas of cybersecurity, intelligence, missile defense, C5ISR, space, geospatial, and connected communities. By combining our talented team of professionals and advanced technology, we help solve complex technical challenges to enable a safer, smarter and more interconnected world. We operate in two reporting segments, Federal Solutions and Critical Infrastructure. Our Federal Solutions business provides advanced technical solutions to the U.S. government. Our Critical Infrastructure business provides integrated engineering and management services for complex physical and digital infrastructure to state and local governments and large companies. Our employees provide services pursuant to contracts that we are awarded by the customer and specific task orders relating to such contracts. These contracts are often multi-year, which provides us backlog and visibility on our revenues for future periods. Many of our contracts and task orders are subject to renewal and rebidding at the end of their term, and some are subject to the exercise of contract options and issuance of task orders by the applicable government entity. In addition to focusing on increasing our revenues through increased contract awards and backlog, we focus our financial performance on margin expansion and cash flow. 54 We manage and assess the performance of our business by evaluating a variety of metrics. The following table sets forth selected key metrics (in thousands, except Book-to-Bill): Key Metrics Fiscal Year Ended December 31, 2020 December 31, 2019 December 31, 2018 Awards . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Awards Awards generally represent the amount of revenue expected to be earned in the future from funded and unfunded contract awards received during the period. Contract awards include both new and re-compete contracts and task orders. Given that new contract awards generate growth, we closely track our new awards each year. The following table summarizes the total value of new awards for the periods presented below (in thousands): Fiscal Year Ended December 31, 2020 December 31, 2019 December 31, 2018 Federal Solutions . . . . . . . . . . . . . . . . . . . . . . . .

The volume of contract awards can fluctuate in any given period due to win rate and the timing and size of the awards issued by our customers. In Federals Solutions, large awards in 2019 were the primary driver of changes in awards between 2020, 2019 and 2018. Awards in Critical infrastructure were lower in 2019 due to potential awards being pushed out to 2020. Backlog We define backlog to include the following two components: • Funded—Funded backlog represents the revenue value of orders for services under existing contracts for which funding is appropriated or otherwise authorized less revenue previously recognized on these contracts. • Unfunded—Unfunded backlog represents the revenue value of orders for services under existing contracts for which funding has not been appropriated or otherwise authorized less revenue previously recognized on these contracts. Backlog includes (i) unissued task orders and unexercised option years, to the extent their issuance or exercise is probable, as well as (ii) contract awards, to the extent we believe contract execution and funding is probable. 55 The following table summarizes the value of our backlog at the respective dates presented (in thousands): As of December 31, 2020 December 31, 2019 December 31, 2018 Federal Solutions: Funded . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Our backlog includes orders under contracts that in some cases extend for several years. For example, the U.S. Congress generally appropriates funds for our U.S. federal government customers on a yearly basis, even though their contracts with us may call for performance that is expected to take a number of years to complete. As a result, our federal contracts typically are only partially funded at any point during their term. All or some of the work to be performed under the contracts may remain unfunded unless and until the U.S. Congress makes subsequent appropriations and the procuring agency allocates funding to the contract. We expect to recognize $2.7 billion of our funded backlog at December 31, 2020 as revenues in the following twelve months. However, our U.S. federal government customers may cancel their contracts with us at any time through a termination for convenience or may elect to not exercise option periods under such contracts. In the case of a termination for convenience, we would not receive anticipated future revenues, but would generally be permitted to recover all or a portion of our incurred costs and fees for work performed. See “Risk Factors—Risks Relating to Our Business—We may not realize the full value of our backlog, which may result in lower than expected revenue.” The changes in backlog in our Federal Solutions segment between 2019 and 2020 included contributions of $0.2 billion from business acquisitions. The change in backlog in our Critical Infrastructure segment between 2019 and 2020 was primarily from ordinary course fluctuations in our business and the impacts related to awards discussed above. The changes in backlog in our Federal Solutions segment between 2018 and 2019 included contributions of $0.3 billion from business acquisitions. Backlog in our Critical Infrastructure segment, in 2019, was impacted primarily by a number of potential awards being pushed out to 2020. Our backlog will fluctuate in any given period based on the volume of awards issued in comparison to the revenue generated from our existing contracts. Book-to-Bill Book-to-bill is the ratio of total awards to total revenue recorded in the same period. Our management believes our book-to-bill ratio is a useful indicator of our potential future revenue growth in that it measures the rate at which we are generating new awards compared to the Company’s current revenue. To drive future revenue growth, our goal is for the level of awards in a given period to exceed the revenue booked. A book-to-bill ratio greater than 1.0 indicates that awards generated in a given period exceeded the revenue 56 recognized in the same period, while a book-to-bill ratio of less than 1.0 indicates that awards generated in such period were less than the revenue recognized in such period. The following table sets forth the book-to-bill ratio for the periods presented below: Fiscal Year Ended December 31, 2020 December 31, 2019 December 31, 2018 Federal Solutions . . . . . . . . . . . . . . . . . . . . . . . .

Our operating performance will depend upon many variables, including the success of our growth strategies and the timing and size of investments and expenditures that we choose to undertake, as well as market growth and other factors that are not within our control. Government Spending Changes in the relative mix of government spending and areas of spending growth, with shifts in priorities on homeland security, intelligence, defense-related programs, infrastructure and urbanization, and continued increased spending on technology and innovation, including cybersecurity, artificial intelligence, connected communities and physical infrastructure, could impact our business and results of operations. Cost-cutting and efficiency initiatives, current and future budget restrictions, spending cuts and other efforts to reduce government spending could cause our government customers to reduce or delay funding or invest appropriated funds on a less consistent basis or not at all, and demand for our solutions or services could diminish. Furthermore, any disruption in the functioning of government agencies, including as a result of government closures and shutdowns, could have a negative impact on our operations and cause us to lose revenue or incur additional costs due to, among other things, our inability to deploy our staff to customer locations or facilities as a result of such disruptions. Federal Budget Uncertainty There is uncertainty around the timing, extent, nature and effect of Congressional and other U.S. government actions to address budgetary constraints, caps on the discretionary budget for defense and non-defense departments and agencies, and the ability of Congress to determine how to allocate the available budget authority and pass appropriations bills to fund both U.S. government departments and agencies that are, and those that are not, subject to the caps. Additionally, budget deficits and the growing U.S. national debt increase pressure on the U.S. government to reduce federal spending across all federal agencies, with uncertainty about the size and timing of those reductions. Furthermore, delays in the completion of future U.S. government budgets could in the future delay procurement of the federal government services we provide. A reduction in the amount of, or delays, or cancellations of funding for, services that we are contracted to provide to the U.S. government as a result of any of these impacts or related initiatives, legislation or otherwise could have a material adverse effect on our business and results of operations. Regulations Increased audit, review, investigation and general scrutiny by government agencies of performance under government contracts and compliance with the terms of those contracts and applicable laws could affect our operating results. Negative publicity and increased scrutiny of government contractors in general, including us, 57 relating to government expenditures for contractor services and incidents involving the mishandling of sensitive or classified information, as well as the increasingly complex requirements of the U.S. Department of Defense and the U.S. intelligence community, including those related to cybersecurity, could impact our ability to perform in the markets we serve. Competitive Markets The industries we operate in consist of a large number of enterprises ranging from small, niche-oriented companies to multi-billion-dollar corporations that serve many government and commercial customers. We compete on the basis of our technical expertise, technological innovation, our ability to deliver cost-effective multi-faceted services in a timely manner, our reputation and relationships with our customers, qualified and/or security-clearance personnel, and pricing. We believe that we are well positioned to take advantage of the markets in which we operate because of our proven track record, long-term customer relationships, technology innovation, scalable and agile business offerings and world class talent. Our ability to effectively deliver on project engagements and successfully assist our customers affects our ability to win new contracts and drives our financial performance. Acquired Operations Polaris Alpha On May 31, 2018, we acquired Polaris Alpha for $489.1 million. Polaris Alpha is an advanced, technology- focused provider of innovative mission solutions for national security, intelligence and other U.S. federal customers. The acquisition was funded by cash on-hand and borrowings under our revolving credit facility (the “Revolving Credit Facility”). The financial results of Polaris Alpha have been included in our consolidated results of operations from May 31, 2018 onward. OGSystems On January 7, 2019, we acquired OGSystems for $292.4 million. OGSystems provides geospatial intelligence, big data analytics and threat mitigation for defense and intelligence customers. The acquisition was funded by cash on-hand and borrowings under our Term Loan and Revolving Credit Facility. The financial results of OGSystems have been included in our consolidated results of operations from January 7, 2019 onward. QRC Technologies On July 31, 2019, we acquired QRC Technologies for $214.1 million. QRC Technologies provides design and development of open-architecture radio-frequency products. The acquisition was funded by cash on-hand and borrowings under our Revolving Credit Facility. The financial results of QRC Technologies have been included in our consolidated results of operations from July 31, 2019 onward. Braxton Science & Technology Group, LLC On November 19, 2020, we acquired Braxton for $310.9 million. Braxton operates at the forefront of satellite operations, ground system automation, flight dynamics, and spacecraft and antenna simulation for the U.S. Department of Defense and Intelligence Community. The acquisition was funded by cash on-hand. The financial results of Braxton have been included in our consolidated results of operations from November 19, 2020 onward. Seasonality Our results may be affected by variances as a result of weather conditions and contract award seasonality impacts that we experience across our businesses. The latter issue is typically driven by the U.S. federal 58 government fiscal year-end, September 30. While not certain, it is not uncommon for U.S. government agencies to award task orders or complete other contract actions in the weeks before the end of the U.S. federal government fiscal year in order to avoid the loss of unexpended U.S. federal government fiscal year funds. In addition, we have also historically experienced higher bid and proposal costs in the months leading up to the U.S. federal government fiscal year-end as we pursue new contract opportunities expected to be awarded early in the following U.S. federal government fiscal year as a result of funding appropriated for that U.S. federal government fiscal year. Furthermore, many U.S. state governments with fiscal years ending on June 30 tend to accelerate spending during their first quarter, when new funding becomes available. We may continue to experience this seasonality in future periods, and our results of operations may be affected by it. Taxes Historically, we had elected to be taxed under the provisions of Subchapter “S” of the Internal Revenue Code for federal tax purposes. As a result, our income had not been subject to U.S. federal income taxes or state income taxes in those states where the “S” Corporation status was recognized. No provision or liability for federal or state income tax had been provided in our consolidated financial statements, prior to the IPO on May 8, 2019, except for those states where the “S” Corporation status was not recognized or where states imposed a tax on “S” Corporations. The provision for income tax in the historical periods prior to the IPO consists of these state taxes and from certain foreign jurisdictions where we are subject to tax. In connection with the IPO, our “S” Corporation status terminated, and we are now treated as a “C” Corporation under Subchapter C of the Internal Revenue Code. The revocation of the our “S” Corporation election had a material impact on our results of operations, financial condition and cash flows. The effective tax rate has increased, and net income has decreased as compared to our “S” Corporation tax years, since we are now subject to both U.S. federal and state corporate income taxes on its earnings. Results of Operations Revenue Our revenue consists of both services provided by our employees and pass-through fees from subcontractors and other direct costs. Our Federal Solutions segment derives revenue primarily from the U.S. federal government and our Critical Infrastructure segment derives revenue primarily from government and commercial customers. We recognize revenue for work performed under cost-plus, time-and-materials and fixed-price contracts as follows: Under cost-plus contracts, we are reimbursed for allowable or otherwise defined costs incurred, plus a fee. The contracts may also include incentives for various performance criteria, including quality, timeliness, safety and cost-effectiveness. In addition, costs are generally subject to review by clients and regulatory audit agencies, and such reviews could result in costs being disputed as non-reimbursable under the terms of the contract. Under time-and-materials contracts, hourly billing rates are negotiated and charged to clients based on the actual time spent on a project. In addition, clients reimburse actual out-of-pocket costs for other direct costs and expenses that are incurred in connection with the performance under the contract. Under fixed-price contracts, clients pay an agreed fixed-amount negotiated in advance for a specified scope of work. Refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations— Critical Accounting Policies and Estimates” and “Note 2—Summary of Significant Accounting Polices” in the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for a further description of our policies on revenue recognition. 59 The table below presents the percentage of total revenue for each type of contract. Fiscal Year Ended December 31, 2020 December 31, 2019 December 31, 2018 Fixed-price . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Under cost-plus contracts, there is limited financial risk, because we are reimbursed for all allowable costs up to a ceiling. However, profit margins on this type of contract tend to be lower than on time-and-materials and fixed-price contracts. Under time-and-materials contracts, we are reimbursed for the hours worked using the predetermined hourly rates for each labor category. In addition, we are typically reimbursed for other direct contract costs and expenses at cost. We assume financial risk on time-and-materials contracts because our labor costs may exceed the negotiated billing rates. Profit margins on well-managed time-and-materials contracts tend to be higher than profit margins on cost-plus contracts as long as we are able to staff those contracts with people who have an appropriate skill set. Under fixed-price contracts, we are required to deliver the objectives under the contract for a pre-determined price. Compared to time-and-materials and cost-plus contracts, fixed-price contracts generally offer higher profit margin opportunities because we receive the full benefit of any cost savings, but they also generally involve greater financial risk because we bear the risk of any cost overruns. In the aggregate, the contract type mix in our revenue for any given period will affect that period’s profitability. Over time, we have experienced a relatively stable contract mix. Our recognition of profit on long-term contracts requires the use of assumptions related to transaction price and total cost of completion. Estimates are continually evaluated as work progresses and are revised when necessary. When a change in estimated cost or transaction price is determined to have an impact on contract profit, we record a positive or negative adjustment to revenue. In 2020, 2019 and 2018, no single contract accounted for more than 5% of our revenue. Joint Ventures We conduct a portion of our business through joint ventures or similar partnership arrangements. For the joint ventures we control, we consolidate all the revenues and expenses in our consolidated statements of income (including revenues and expenses attributable to noncontrolling interests). For the joint ventures we do not control, we recognize equity in earnings of unconsolidated joint ventures. Our revenues included $172.2 million in 2020, $157.3 million in 2019, and $144.7 million in 2018 related to services we provided to our unconsolidated joint ventures. Operating costs and expenses Operating costs and expenses primarily include direct costs of contracts and indirect, general and administrative expenses. Costs associated with compensation-related expenses for our people and facilities, which includes ESOP contribution expenses, are the most significant component of our operating expenses. In 2020, 2019 and 2018, we made annual contributions to the ESOP in the amount of 8% of the participants’ cash compensation for the applicable year. Total ESOP contribution expense was $55.3 million for 2020, $53.6 million for fiscal 2019, and $45.2 million for fiscal 2018, and is recorded in “Direct cost of contracts” and “Indirect, general and administrative expenses.” We expect operating expenses to increase due to our anticipated growth. However, on a forward-looking basis, we generally expect these costs to decline as a percentage of our total revenue as we realize the benefits of scale. 60 Direct costs of contracts consist of direct labor and associated fringe benefits, indirect overhead, subcontractor and materials (“pass-through costs”), travel expenses and other expenses incurred to perform on contracts. Indirect, general and administrative expenses (“IG&A”) include salaries and wages and fringe benefits of our employees not performing work directly for customers, facility costs and other costs related to these indirect functions. Other income and expenses Other income and expenses primarily consist of interest income, interest expense, other income, net and interest and other expense associated with claim on long-term contract. Interest income primarily consists of interest earned on U.S. government money market funds. Interest expense consists of interest expense incurred under our Senior Notes, Convertible Senior Notes, and Credit Agreement. Other income, net primarily consists of gain or loss on sale of assets, sublease income and transaction gain or loss related to movements in foreign currency exchange rates. Included in other income and expenses in 2018 are amounts related to the settlement of a lawsuit in favor of a joint venture in which the Company was the managing partner. With regard to the lawsuit, during the second half of fiscal 2013, a California state court issued a number of preliminary judgments with the final judgment being rendered in early fiscal 2014 in favor of the plaintiff in a lawsuit against the joint venture. We recorded a loss of $98.8 million for fiscal 2013 as a result of these judgments, which included the reversal of $55.1 million in previously recognized revenue. Post-judgment interest was accrued through May 2018 when a total of $133.1 million was accrued in “Provision for contract losses of consolidated joint ventures” on our consolidated balance sheet. On February 28, 2018, the California Court of Appeals vacated the judgement, and in doing so, the appellate court remanded the case to the trial court for the sole purpose of entering a new and final judgement in our favor. On April 9, 2018, the appellate court ruling was appealed by the counterparty to the California Supreme Court. On June 13, 2018, the California Supreme Court denied the counterparty’s appeal. As a result, in the second quarter of 2018 we reversed $133.1 million accrued in “Provision for contract losses on consolidated joint ventures” on our consolidated balance sheet, resulting in a net gain of $129.7 million on our consolidated statements of income, of which $55.1 million was recorded as an increase in revenue with the remainder recorded as other income. 61 Year ended December 31, 2020 compared to year ended December 31, 2019 The following table sets forth our results of operations for fiscal 2020 and fiscal 2019 as a percentage of revenue.

This decrease was primarily due to a decrease in revenue in our Critical Infrastructure segment of $59.9 million partially offset by an increase in our Federal Solutions segment of $24.0 million.

Indirect, general and administrative expenses (U.S. dollars in thousands) Fiscal Year Ended Variance December 31, 2020 December 31, 2019 Dollar Percent Indirect, general and administrative expenses . . . . . . . . . . . . . . . $729,103 $781,408 $(52,305) -6.7% The decrease in IG&A expenses for the years ended December 31, 2020 as compared to December 31, 2019 relates primarily to a decline in compensation cost associated with equity-based awards that settle primarily in cash. The compensation cost associated with these awards totaled $9.8 million during the year ended December 31, 2020 as compared to $65.7 million for the year ended December 31, 2019. Cash settled awards are remeasured to an updated fair value at each reporting period until the award is settled. Compensation cost is trued-up at each reporting period for changes in fair value pro-rated for the portion of the requisite service period rendered. The significant decrease in compensation cost related to these cash settled equity-based awards for the year ended December 31, 2020 compared to December 31, 2019 is due primarily to lower share prices over the last 60 trading days of 2020 as compared to the comparable period in 2019, as well as the higher grant price of active awards in 2020. The substantial compensation cost for the year ended December 31, 2019 was due to the significant difference in the fair value of a share of our common stock under Parsons ESOP valuation at December 31, 2018 compared to the fair value of a share of our common stock in the public market at December 31, 2019. See Item 5 of Part II for ranges in the share price of our common stock since the consummation of the IPO and “Note 19—Fair Value of Financial Instruments” in the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for a description of how the ESOP share value was determined. See “Note 1—Description of Operations” in the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for more detail regarding our IPO. The plans in which these awards were granted have been frozen and the Company does not currently intend to grant any further cash settled equity-based awards. Excluding the compensation costs discussed above, IG&A for the years ended December 31, 2020 and December 31, 2019 was $719.3 million and $715.7 million, respectively. The increase in IG&A of $3.6 million, exclusive of equity compensation cost, was primarily due to additional expenses of $23.8 million associated with business acquisitions, $3.9 million due to a tax law change and $5.0 million related to strategic growth initiatives and public company operating costs. These increases were partially offset by a $18.4 million reduction in transaction-related costs related primarily to our initial public offering in 2019, and a $10.1 million reduction in intangible asset amortization. 63 Total other (expense) income (U.S. dollars in thousands) Fiscal Year Ended Variance December 31, 2020 December 31, 2019 Dollar Percent Interest income . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Income tax expense (U.S. dollars in thousands) Fiscal Year Ended Variance December 31, 2020 December 31, 2019 Dollar Percent Income tax expense (benefit) . . . . . . . . . . . . . . . . . . . . . . . . . . . . $42,492 $(69,886) $112,378 160.8% Income tax expense increased in fiscal 2020 primarily due to the nonrecurring tax items included in 2019 for tax benefits associated with the remeasurement of our net deferred tax assets as a result of our conversion from “S” Corporation to a “C” Corporation. Our effective tax rate was 26.3% and income tax expense was $42.5 million for the year ended December 31, 2020. As described in “Note 14 – Income Taxes,” in the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K, in connection with our IPO on May 8, 2019, we converted from an “S” Corporation to a “C” Corporation. On a pro forma basis, if we had been taxed as a “C” Corporation for the year ended December 31, 2019, the pro forma effective tax rate would have been 36.9%, and our pro forma income tax expense would have been $24.8 million. The most significant items contributing to the change in the effective tax rate relates to a change in jurisdictional earnings, federal research tax credits and a nonrecurring item included in 2019 associated with equity compensation. The difference between the statutory U.S. federal income tax rate of 21% and the effective tax rate for the year ended December 31, 2020 primarily relates to state income taxes and a recorded valuation allowance on foreign tax credits, partially offset by benefits related to income attributable to noncontrolling interest and federal research tax credits. The termination of the “S” Corporation status was treated as a change in tax status for Accounting Standards Codification 740, Income Taxes. These rules require that the deferred tax effects of a change in tax status to be recorded to income from continuing operations on the date the “S” Corporation status terminates. At December 31, 2019, the Company had recorded a deferred tax benefit of $93.9 million for the estimated effect of the change in tax status, relating to the recognition of net deferred tax assets for temporary differences in existence on the date of conversion to a “C” Corporation. This estimated amount was adjusted to $90.0 million upon filing of the 2019 tax returns. This adjustment is included in income tax expense for the year ended December 31, 2020. 64 Year ended December 31, 2019 compared to year ended December 31, 2018 The following table sets forth our results of operations for 2019 and 2018 as a percentage of revenue.

See “Results of Operations—Other income and expenses” above for a description of this matter. Excluding the claim settlement, revenue increased $449.4 million for the year ended December 31, 2019 when compared to the prior year, primarily due to an increase in revenue in our Federal Solutions segment of $408.9 million and an increase in our Critical Infrastructure segment of $40.5 million.

The increase in our Federal Solutions segment was due primarily to business acquisitions, which added $239.4 million, and $50.2 million from an increase in business volume on existing contracts, offset by the completion of a significant contract. The change in our Critical Infrastructure segment was primarily due to an increase in business volume on existing contracts, along with normal course fluctuations in the winding down and starting up of contracts. 65 Equity in earnings of unconsolidated joint ventures (U.S. dollars in thousands) Fiscal Year Ended Variance December 31, 2019 December 31, 2018 Dollar Percent Equity in earnings of unconsolidated joint ventures . . . . . . . . . . . . $41,721 $36,915 $4,806 13.0% Equity in earnings of unconsolidated joint ventures increased in fiscal 2019 primarily due to increased activity under a number of the Company’s existing joint ventures, offset by the completion of a significant joint venture during the year.

Compensation cost is trued-up at each reporting period for changes in fair value pro-rated for the portion of the requisite service period rendered. The significant increase in compensation cost related to these cash settled equity-based awards for the year ended December 31, 2019 is due to the significant difference in the fair value of a share of our common stock under Parsons ESOP valuation at December 31, 2018 compared to the fair value of a share of our common stock in the public market at December 31, 2019.

Excluding the compensation costs discussed above, IG&A for the years ended December 31, 2019 and December 31, 2018 were $715.7 million and $580.9 million, respectively. The increase in IG&A of $134.8 million for the year ended December 31, 2019 when compared to the prior year was primarily due to our Federal Solutions segment, most of which is related to additional expenses of $47.8 million from business acquisitions, $50.9 million from the amortization of intangible assets related to our acquisitions and $11.2 million in acquisition-related expenses. The remaining increase of $24.9 million is related to additional bid and proposal costs and an increase in corporate functional group costs. 66 Total other income (expense) (U.S. dollars in thousands) Fiscal Year Ended Variance December 31, 2019 December 31, 2018 Dollar Percent Interest income . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

As described in “Note 14 – Income Taxes,” in the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K, in connection with our IPO on May 8, 2019, we converted from an “S” Corporation to a “C” Corporation. On a pro forma basis, if we had been taxed as a “C” Corporation for the years ended December 31, 2019 and December 31, 2018, the pro forma effective tax rate would have been 36.89% and 28.77%, respectively, and our pro forma income tax expense would have been $24.8 million and $74.8 million, respectively. The most significant item contributing to the change in the effective tax rate relates to a change in jurisdictional earnings. The difference between the statutory U.S. federal income tax rate of 21% and the effective tax rate for the year ended December 31, 2019 primarily relates to foreign earnings which are subject to foreign income taxes at rates that exceed the U.S. income tax rate. The termination of the “S” Corporation status was treated as a change in tax status for Accounting Standards Codification 740, Income Taxes. These rules require that the deferred tax effects of a change in tax status to be recorded to income from continuing operations on the date the “S” Corporation status terminates. Through the year ended December 31, 2019, the Company recorded a deferred tax benefit of $93.9 million for the estimated effect of the change in tax status, relating to the recognition of net deferred tax assets for temporary differences in existence on the date of conversion to a “C” Corporation. 67 Segment Results We evaluate segment operating performance using segment revenue and segment Adjusted EBITDA attributable to Parsons Corporation. Adjusted EBITDA attributable to Parsons Corporation is Adjusted EBITDA excluding Adjusted EBITDA attributable to noncontrolling interests. See “Selected Financial Data” for a discussion of our definition of Adjusted EBITDA, how we use this metric, why we present this metric and the material limitations on the usefulness of this metric. See “Note 21—Segments Information” in the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for further discussion regarding our segment Adjusted EBITDA attributable to Parsons Corporation. The following table shows Adjusted EBITDA attributable to Parsons Corporation for each of our reportable segments and Adjusted EBITDA attributable to noncontrolling interests: (U.S. dollars in thousands) Federal Solutions Adjusted EBITDA attributable to Parsons Fiscal Year Ended December 31, 2020 December 31, 2019 December 31, 2018 Corporation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $167,340 $169,100 $121,986 Critical Infrastructure Adjusted EBITDA attributable to Parsons Corporation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Federal Solutions organic revenue grew $91.5 million, which included significant incentive fee recognition and an increase in business volume on existing contracts, offset by the completion of a significant contract. The increase in Federal Solutions Adjusted EBITDA attributable to Parsons Corporation for the year ended December 31, 2019 compared to the previous year was primarily due to business acquisitions, an increase in business volume on existing contracts, and generally higher profit margins driven by significant incentive fee recognition. These increases were partially offset by an increase in IG&A, driven by an increase in bid and proposal costs and a greater allocation of corporate IG&A in line with the segment’s growing share of overall business, as well as the completion of a significant contract.

Excluding the claim settlement, revenue for the year ended December 31, 2019 compared to the previous year increased $44.2 million. This increase in revenue was primarily related to an increase in business volume under existing contracts, along with normal course fluctuations in the winding down and starting up of contracts. The increase in Critical Infrastructure Adjusted EBITDA attributable to Parsons for the year ended December 31, 2019 compared to the previous year was primarily due to an increase in business volume, a decrease in IG&A, primarily due to a lower allocation of corporate IG&A in line with the segment’s share of overall business, and an increase in equity in earnings of unconsolidated joint ventures. 69 Liquidity and Capital Resources We currently finance our operations and capital expenditures through a combination of internally generated cash from operations, our Senior Notes, Convertible Senior Notes, and periodic borrowings under our Revolving Credit Facility. Prior to November 3, 2019, we financed our operations, capital expenditures and redemptions of ESOP through a combination of internally generated cash from operations, our Senior Notes, and periodic borrowings under our Revolving Credit facility. After November 3, 2019, all shares held by the ESOP are redeemable by participants in shares of our common stock once vesting and eligibility requirements have been met. See “Critical Accounting Policies and Estimates” elsewhere in this Annual Report on Form 10-K for a discussion of the ESOP and related IPO matters. Generally, cash provided by operating activities has been adequate to fund our operations. Due to fluctuations in our cash flows and growth in our operations, it may be necessary from time to time in the future to borrow under our Credit Agreement to meet cash demands. Our management regularly monitors certain liquidity measures to monitor performance. We calculate our available liquidity as a sum of cash and cash equivalents from our consolidated balance sheet plus the amount available and unutilized on our Credit Agreement. There are likely to be certain impacts in our ability to collect accounts receivable as a result of the economic impacts from the COVID-19 pandemic. Accounts receivable reflect amounts due from both commercial and government customers. Our commercial customers are comprised principally of large, well-known and well- established companies. Our government customers are comprised principally of national, state and local agencies in the U.S. and Middle East. We have not seen and do not expect there to be a material risk of non-payment from either our government agency or commercial customers. We have experienced payment delays due to administrative limitations from both types of customers. We believe we have adequate liquidity and capital resources to fund our operations, support our debt service and support our ongoing acquisition strategy for at least the next twelve months based on the liquidity from cash provided by our operating activities, cash and cash equivalents on-hand and our borrowing capacity under our Revolving Credit Facility. We do not anticipate that the COVID-19 pandemic-related economic impacts will impair our ability to continue to maintain compliance with its debt covenants or access available borrowing capacity from our banks. Cash Flows Cash received from customers, either from the payment of invoices for work performed or for advances in excess of revenue recognized, is our primary source of cash. We generally do not begin work on contracts until funding is appropriated by the customers. Billing timetables and payment terms on our contracts vary based on a number of factors, including whether the contract type is cost-plus, time-and-materials, or fixed-price. We generally bill and collect cash more frequently under cost-plus and time-and-materials contracts, as we are authorized to bill as the costs are incurred or work is performed. In contrast, we may be limited to bill certain fixed-price contracts only when specified milestones, including deliveries, are achieved. A number of our contracts may provide for performance-based payments, which allow us to bill and collect cash prior to completing the work. Billed accounts receivable represents amounts billed to clients that have not been collected. Unbilled accounts receivable represents amounts where the Company has a present contractual right to bill but an invoice has not been issued to the customer at the period-end date. Accounts receivable is the principal component of our working capital and is generally driven by revenue growth. Accounts receivable includes billed and unbilled amounts. The total amount of our accounts receivable can vary significantly over time, but is generally sensitive to revenue levels. We experience delays in collections from time to time from Middle East customers. Net days sales outstanding, which we refer to as net DSO, is 70 calculated by dividing (i) accounts receivable (net of project accruals, billings in excess of revenue and accounts payable) by (ii) average revenue per day (calculated by dividing trailing twelve months revenue by the number of days in that period). We focus on collecting outstanding receivables to reduce Net DSO and working capital. Net DSO was 64 days at December 31, 2020, 55 days at December 31, 2019 and 52 days at December 31, 2018. Our working capital (current assets less current liabilities) was $705.7 million at December 31, 2020, $382.0 million at December 31, 2019 and $482.6 million at December 31, 2018. Our cash, cash equivalents and restricted cash increased by $206.0 million to $487.2 million at December 31, 2020 from $195.4 million at December 31, 2019. This compares to a decrease in cash, cash equivalents and restricted cash of $85.8 million to $195.4 million at December 31, 2019 from $281.2 million at December 31, 2018. The following table summarizes our sources and uses of cash over the periods presented (in thousands): Fiscal Year Ended December 31, 2020 December 31, 2019 December 31, 2018 Net cash provided by operating activities . . . . .

The timing between the conversion of our billed and unbilled receivables into cash from our customers and disbursements to our employees and vendors is the primary driver of changes in our working capital. Our operating cash flows are primarily affected by our ability to invoice and collect from our clients in a timely manner, our ability to manage our vendor payments and the overall profitability of our contracts. Net cash provided by operating activities increased $68.9 million to $289.2 million during 2020 compared to $220.2 million during 2019. The increase in net cash provided by operating activities is primarily due to a $115.9 million change in net income after adjusting for non-cash items and a change in the use of cash related to our working capital accounts of $10.6 million (primarily from accounts receivable, contract assets, prepaid expenses and current assets, offset by accrued expenses and contract liabilities). Under the CARES Act, the Company received a net cash benefit of $35.2 million from the deferral of social security taxes otherwise due from April 10, 2020 through the year ended December 31, 2020. One-half of the deferred amount is due no later than December 31, 2021 and the second half no later than December 31, 2022. These positive changes in operating cash flows were offset, in part, by a $57.6 million change in other long-term liabilities, primarily driven by the payment of long-term employee incentives. Net DSOs increased from 55 days to 64 days primarily driven by the change in our working capital accounts discussed above. Net cash provided by operating activities decreased $64.4 million to $220.2 million during 2019 compared to $284.6 million during 2018. The decrease in net cash provided by operating activities is primarily due to a change in the use of cash related to our working capital accounts of $64.1 million (primarily driven by growth in accounts receivable and contract assets net of contract liabilities), and a $8.8 million change in net income after 71 adjusting for non-cash items. These negative changes in operating cash flows were offset, in part, by a $8.6 million change in other long-term liabilities, primarily related to our insurance reserves. Net DSOs increased from 52 days to 55 days primarily driven by the change in our working capital accounts discussed above. In connection with our IPO on May 8, 2019, the Company converted from an “S” Corporation to a “C” Corporation as described in “Note 14 – Income Taxes” in the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K. As a “C” Corporation we are now subject to U.S. Income Taxes. During 2019 the Company made $60.5 million in tax payments compared with $17.1 million in tax payments during 2018. Investing Activities Net cash used in investing activities consists primarily of cash flows associated with capital expenditures and business acquisitions. Net cash used in investing activities decreased $224.4 million during 2020 compared to 2019, primarily due to the use of $287.5 million, net of cash acquired, for the acquisition of OGSystems and the use of $208.2 million, net of cash acquired, for the acquisition of QRC Technologies in 2019, compared to $302.4 million, net of cash acquired, for the acquisition of Braxton in 2020. Net cash used in investing activities increased $67.5 million during 2019 compared to 2018, primarily due to an increase in cash used for capital expenditures of $38.3 million, principally related to our office space, investments in unconsolidated joint ventures of $19.9 million, and payments for acquisitions, net of cash acquired of $13.7 million. Financing Activities Net cash provided by financing activities is primarily associated with proceeds from debt, the repayment thereof, distributions to noncontrolling interests and payments to the ESOP in connection with the redemption of ESOP participants’ interests prior to the 180-day lock-up period which ended November 3, 2019. We spent $0 in 2020, $6.3 million in 2019, and $125.8 million in 2018 in connection with the redemption of ESOP participants’ interests. With a public market for our common stock, cash is no longer required for ESOP redemptions after November 3, 2019. Participants now receive distributions of their ESOP interests in shares of our common stock. Net cash provided by financing activities increased $82.2 million to $348.2 million in 2020 compared to $266.0 million in 2019. 2020 activities include $348.5 million of net proceeds from the issuance of Convertible Senior Notes. 2019 activities are primarily comprised of $536.9 million of net proceeds from the IPO, offset in part by net repayments under our revolving credit agreement of $180 million and payment of the IPO dividend of $52.1 million. Net cash provided by financing activities increased $210.6 million in 2019 compared to 2018, primarily due to $536.9 million of net proceeds from the IPO and a reduction of $119.5 million in the purchases of treasury stock related to redemptions of ESOP interests in 2019. These changes in cash flow provided by financing activities were offset, in part, by a change in net repayments under our revolving credit agreement of $360.0 million, payment of the IPO dividend of $52.1 million, an increase of $23.4 million in distributions to noncontrolling interests and a decrease of $10.6 million in contributions by noncontrolling interests. Letters of Credit We also have in place several secondary bank credit lines for issuing letters of credit, principally for foreign contracts, to support performance and completion guarantees. Letters of credit commitments outstanding under these bank lines aggregated $193.1 million as of December 31, 2020. Letters of credit outstanding under the Credit Agreement total $44.9 million. 72 Contractual Obligations The following table summarizes our contractual obligations that require us to make future cash payments as of December 31, 2020.

See “Note 12—Debt and Credit Facilities” in the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for additional information regarding our debt and related matters. In August 2020, the Company issued an aggregate $400.0 million of 0.25% Convertible Senior Notes due 2025, unless earlier converted, redeemed, or repurchased. Contractual obligation consists of principal and interest. See “Note 12—Debt and Credit Facilities” in the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for additional information regarding our debt and related matters. In the normal course of business, we enter into agreements with subcontractors and vendors to provide products and services that we consume in our operations or that are delivered to our clients. These products and services are not considered unconditional obligations until the products and services are actually delivered, at which time, we record a liability for our obligation. Critical Accounting Policies and Estimates Our significant accounting policies are described in “Note 2—Summary of Significant Accounting Policies” in the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K. Management makes estimates and judgments in preparing our consolidated financial statements. These estimates and judgments affect the reported amounts of certain assets and liabilities and the revenues and expenses reported for the periods presented in the consolidated financial statements. Although such estimates and assumptions are based on information available through the date of the issuance of our consolidated financial statements, actual results could differ significantly from those estimates and assumptions. Our estimates, judgments and assumptions are evaluated periodically and adjusted accordingly. We believe that the following items are the most critical accounting policies and estimates that involved significant judgment as we prepared our financial statements. We consider an accounting policy or estimate to be critical if the policy or estimate requires assumptions to be made that were uncertain at the time they were made and if changes in these assumptions could have a material impact on our financial condition or results of operations. Revenue Recognition and Cost Estimation On December 30, 2017, the Company adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, (“ASC 606”), using the modified retrospective method, which provides for a cumulative effect adjustment to retained earnings beginning in fiscal 2018 for those uncompleted contracts impacted by the adoption of the new standard. The difference between the recognition criteria under ASC-606 73 and our previous recognition practices under ASC 605-35 was recognized through a cumulative adjustment of $4.7 million that was made to the opening balance of accumulated deficit as of December 30, 2017. The cumulative effect of adopting ASC 606 was primarily due to combining certain deliverables that were previously considered separate deliverables into a single performance obligation and the transition of certain cost-type contracts into the cost-to-cost measure of progress method. Consistent with the modified retrospective transition approach, the comparative fiscal 2017 period was not adjusted to conform to the current period presentation. The following are the significant policies and practices as applied to our business. In our industry, recognition of revenue and profit on long-term contracts requires the use of assumptions and estimates related to total contract revenue, total cost at completion, and the measurement of progress towards completion. Estimates are continually evaluated as work progresses and are revised when necessary. When a change in estimate is determined to have an impact on contract revenue or profit, we record a positive or negative adjustment to the consolidated statements of income. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in ASC 606. The transaction price of a contract is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. To the extent a contract is deemed to have multiple performance obligations, we allocate the transaction price of the contract to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. We determine the relative standalone selling price utilizing observable prices for the sale of the underlying goods or services. Contracts are considered to have a single performance obligation if the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts or is not distinct in the context of the contract, which is mainly because we provide a significant service of integrating a complex set of tasks and components into a single project or capability. Engineering and construction contracts are generally accounted for as a single performance obligation, while our engineering and construction supervision contracts are accounted for as two separate performance obligations. When providing construction supervision services, we are not liable for the construction of the asset, but have an overall responsibility to oversee, coordinate, measure, and evaluate the quality of construction work and the performance of the construction contractor on behalf of the customer. Customers are generally billed as we satisfy our performance obligations and payment terms typically range from 30 to 120 days from the invoice date. Billings under certain fixed-price contracts may be based upon the achievement of specified milestones, while some arrangements may require advance customer payment. Our contracts generally do not include a significant financing component. The transaction price for our contracts may include variable consideration, which includes increases to the transaction price for approved and unpriced change orders, claims and incentives, and reductions to transaction price for liquidated damages. We recognize adjustments in estimated profit on contracts under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to-date is recognized in the period the adjustment is identified. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, we recognize the total loss in the quarter it is identified. Claims revenue is related to amounts in excess of agreed contract price that we seek to collect from clients or others for customer-caused delays, errors in specifications and designs, contract terminations, change orders that are either in dispute or are unapproved as to both price and scope, or other causes of unanticipated additional contract costs, including factors outside of our control, where we therefore believe we are entitled to additional compensation. Claims revenue, when recorded, is only recorded to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. We include certain unapproved claims in the transaction price when the claims are legally enforceable, we consider collection to be probable and believe we can reliably estimate the ultimate value. We continue to engage in negotiations with our customers on our outstanding claims. However, these claims may be resolved at amounts that differ from our current estimates, which could result in increases or decreases in future estimated contract profits or losses. Costs related to claims are recognized when they are incurred. 74 Change orders, which are a normal and recurring part of our business, are generally not distinct and are accounted for as part of the existing contract. The effect of a change order that is not distinct on the transaction price and our measure of progress for the performance obligation to which it relates is recognized on a cumulative catch-up basis. To the extent change orders included in the transaction price are not resolved in our favor, there could be reductions in, or reversals of previously reported amounts of, revenues and profits, and charges against current earnings. Costs relating to change orders are recognized when they are incurred. We recognize revenue for most of our contracts over time as performance obligations are satisfied, as we are continuously transferring control to the customer. Typically, revenue is recognized over time using an input measure (i.e., costs incurred to date relative to total estimated costs at completion) to measure progress. We often enter into contracts in which the amount billed to the customer corresponds directly with the amount of work performed. These contract types qualify for the “right to invoice” practical expedient method of measuring progress, in which the right to consideration corresponds directly with the value to the customer of our performance to date. For these contracts, revenue is recognized in the amount that we have the right to invoice. Provisions for anticipated losses on contracts, including those arising from disputes and other contingencies, are recorded in the period such loss becomes known; provisions not ultimately required are released as disputes or contingencies are resolved. Contract costs include labor and materials, amounts payable to subcontractors, direct overhead costs and equipment expense (primarily depreciation, fuel, maintenance and repairs). All contract costs are recorded as incurred. Changes to estimated contract costs, either due to unexpected events or revisions to management’s initial estimates, for a given project are recognized in the period in which they are determined. Leases In February 2016, the FASB issued ASU 2016-02 “Leases (Topic 842)”, which is a new standard related to leases to increase transparency and comparability among organizations by requiring the recognition of right-of-use (ROU) assets obtained in exchange for lease liabilities on the balance sheet. Most prominent among the changes in the standard is the recognition of ROU assets and lease liabilities by lessees for those leases classified as operating leases. Under the standard, disclosures are required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The Company elected to adopt the standard, and available practical expedients, effective January 1, 2019. These practical expedients allowed the Company to keep the lease classification assessed under the previous lease accounting standard (ASC 840) without reassessment under the new standard, and allowed all separate lease components, including non-lease components, to be accounted for as a single lease component for all existing leases prior to adoption of the new standard. Furthermore, the Company made an accounting policy election to not recognize a lease liability and ROU asset for leases with lease terms of twelve months or less. The Company adopted this new standard under the modified retrospective transition approach without adjusting comparative periods in the financial statements, as allowed under Topic 842, and implemented internal controls and key system functionality to enable the preparation of financial information on adoption. The standard had a material impact on our consolidated balance sheets but did not have an impact on the consolidated income statements. The most significant impact was the recognition of ROU assets and lease liabilities for operating leases, while accounting for finance leases remained substantially unchanged. As a result of the adoption, we recorded a cumulative-effect adjustment to retained earnings of $52.6 million, net of a deferred tax asset adjustment of $0.7 million, representing the unamortized portion of a deferred gain previously recorded as a sale-leaseback transaction associated with the sale of an office building in 75 2011. We concluded the transaction resulted in the transfer of control of the office building to the buyer-lessor at market terms and would have qualified as a sale under Topic 842 with gain recognition in the period the sale was recognized. We determine if an arrangement is a lease at inception. Operating leases are included in operating lease ROU assets and current and long-term operating lease liabilities in the consolidated balance sheets. Finance leases are included in other noncurrent assets, accrued expenses and other current liabilities and other long-term liabilities in the consolidated balance sheets. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit interest rate, incremental borrowing rates are used based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term. We have lease agreements with lease and non-lease components, which are generally accounted for separately. For certain equipment leases, such as vehicles, we account for the lease and non-lease components as a single lease component. Additionally, for certain equipment leases, we apply a portfolio approach to effectively account for the operating lease ROU assets and liabilities. We have operating and finance leases for corporate and project office spaces, vehicles, heavy machinery and office equipment. Our leases have remaining lease terms of one year to 10 years, some of which may include options to extend the leases for up to five years, and some of which may include options to terminate the leases up to the seventh year. Business Combinations The cost of an acquired company is assigned to the tangible and intangible assets purchased and the liabilities assumed on the basis of their fair values at the date of acquisition. The determination of fair values of assets acquired and liabilities assumed requires us to make estimates and use valuation techniques when a market value is not readily available. Any excess of purchase price over the fair value of tangible and intangible assets acquired and obligations assumed is allocated to goodwill. Goodwill typically represents the value paid for the assembled workforce and enhancement of our service offerings. Transaction costs associated with business combinations are expensed as incurred. The determination of fair values of assets acquired and liabilities assumed requires the Company to make estimates and use valuation techniques when a market value is not readily available. The Company adjusts the preliminary purchase prices allocation, as necessary, during the measurement period of up to one year after the acquisition closing date as the Company obtains more information as to facts and circumstances existing at the acquisition date. Goodwill and Intangible Assets Goodwill is not amortized but is subject to an annual impairment test. Interim testing for impairment is performed if indicators of potential impairment exist. For purposes of impairment testing, goodwill is allocated to the applicable reporting units based on the current reporting structure. When evaluating goodwill for impairment, we may decide to first perform a qualitative assessment, or “step zero” impairment test, to determine whether it is more likely than not that impairment has occurred. If we do not perform a qualitative assessment, or if we determine that it is not more likely than not that the fair value of our reporting units exceeds their carrying amounts, we perform a quantitative assessment and calculate the estimated fair value of the respective reporting unit. If the carrying amount of a reporting unit’s goodwill exceeds the fair value of that goodwill, an impairment loss is recognized. 76 Our decision to perform a qualitative impairment assessment in a given year is influenced by a number of factors, including the significance of the excess of our estimated fair value over carrying value at the last quantitative assessment date, the amount of time in between quantitative fair value assessments, and the date of the applicable acquisitions, if any. In 2019, we changed the date of its annual goodwill impairment testing from November 30 to October 1. This change results in better alignment of our annual impairment test with our annual budgeting cycle and provides a more reliable measurement using our interim closing processes. The change had no effect on our consolidated financial statements for the current or historical periods. We perform a goodwill impairment test on an annual basis for each reporting unit that requires certain assumptions and estimates be made regarding industry economic factors and future profitability. For the years ended December 31, 2020, December 31, 2019 and December 31, 2018, we performed a quantitative analysis for all of our reporting units. It was determined that the fair value of each of our reporting units substantially exceeded their carrying values. As a result, no goodwill impairments were identified for those periods. The goodwill impairment test involves determination of the fair value of our reporting units. This process requires significant judgments and estimates, including assumptions about our strategic plans for operations as well as the interpretation of current economic indicators. Development of the present value of future cash flow projections includes assumptions and estimates derived from a review of our expected revenue growth rates, profit margins, business plans, cost of capital and tax rates. We also make certain assumptions about future market conditions, market prices, interest rates and changes in business strategies. Changes in assumptions or estimates could materially affect the determination of the fair value of a reporting unit. This could eliminate the excess of fair value over carrying value of a reporting unit entirely and, in some cases, result in impairment. Such changes in assumptions could be caused by a loss of one or more significant contracts, reductions in government or commercial client spending, or a decline in the demand for our services due to changing economic conditions. In the event that we determine that our goodwill is impaired, we would be required to record a non-cash charge that could result in a material adverse effect on our results of operations or financial position. We use the Income Approach and Market Approach (Guideline Transaction and Guideline Company Method) to determine the fair value of reporting units. The Income Approach utilizes the discounted cash flow method, which focuses on the expected cash flow of the reporting unit. In applying this approach, the cash flow is calculated for a finite period of years. Beyond the finite period, a terminal value is developed using a sustainable long-term annual growth rate estimate. Then the finite period cash flows and the terminal value are discounted to present value to arrive at an indication of fair value. We utilized internal financial projections through fiscal 2025. The Market Approach utilizes market comparable transactions and comparable companies to calculate the estimated fair value. The guideline company approach focuses on comparing the reporting unit to select reasonably similar (or ”guideline”) publicly traded companies. Under this method, valuation multiples are derived from the median of the operating data of selected guideline companies and applied to the operating data of the reporting unit to arrive at an indicative value. In the similar transactions approach, consideration is given to prices paid in recent transactions that have occurred in the reporting unit’s industry or in related industries. For the Federal Solutions reporting unit, only the Guideline Company Method is used as the Federal Solutions reporting unit has gone through multiple acquisitions during the past two years, thus making Guideline Transaction Method difficult to apply. For the Critical Infrastructure reporting unit, both the Guideline Transaction Method and Guideline Company Method are utilized to calculate the estimated fair value. Equal weighing is given to each of the methods used to estimate the fair value of reporting units. Our last review at October 1, 2020 (i.e. the first day of our fourth quarter in fiscal 2020), indicated that we had no impairment of goodwill, and all of our reporting units had estimated fair values that were in excess of their carrying values, including goodwill. We had no reporting units that had estimated fair values that exceeded their carrying values by less than 75%. Intangible assets with finite lives arise from business acquisitions and are amortized based on the period over which the contractual or economic benefit of the intangible assets are expected to be realized or on a 77 straight-line basis over the useful lives of the underlying assets, ranging from one to ten years. These primarily consist of customer relationships, backlog, and covenants not to compete. We assess the recoverability of the unamortized balance of our intangible assets when indicators of impairment are present based on expected future profitability and undiscounted expected cash flows and their contribution to overall operations. Should the review indicate that the carrying value is not fully recoverable, the excess of the carrying value over the fair value of the intangible assets would be recognized as an impairment loss. Consolidation of Joint Ventures and Variable Interest Entities We participate in joint ventures, which include partnerships and partially owned limited liability corporations, to bid, negotiate and complete specific projects. We are required to consolidate these joint ventures if we hold the majority voting interest or if we meet the criteria under the consolidation model as described below. A variable interest entity, or “VIE”, is an entity with one or more of the following characteristics: (a) the total equity investment at risk is not sufficient to permit the entity to finance its activities without additional financial support; (b) as a group, the holders of the equity investment at risk lack the ability to make certain decisions, the obligation to absorb expected losses or the right to receive expected residual returns; or (c) an equity investor has voting rights that are disproportionate to its economic interest and substantially all of the entity’s activities are on behalf of the investor with disproportionately low voting rights. Our VIEs may be funded through contributions, loans and/or advances from the joint venture partners or by advances and/or letters of credit provided by clients. Certain VIEs are directly governed, managed, operated and administered by the joint venture partners. Others have no employees and, although these entities own and hold the contracts with the clients, the services required by the contracts are typically performed by the joint venture partners or by other subcontractors. We are required to perform an analysis to determine whether we are the primary beneficiary of our VIEs. We are deemed to be the primary beneficiary of a VIE if we have (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance; and (ii) the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. Many of the joint ventures we enter into are deemed to be VIEs because they lack sufficient equity to finance the activities of the joint venture. We use a qualitative approach to determine if we are the primary beneficiary of the VIE, which considers factors that indicate a party has the power to direct the activities that most significantly impact the joint venture’s economic performance. In determining whether we are the primary beneficiary of the VIE, significant assumptions and judgments include the following: (1) identifying the significant activities and the parties that have the power to direct them; (2) reviewing the governing board composition and participation ratio; (3) determining the equity, profit and loss ratio; (4) determining the management-sharing ratio; (5) reviewing employment terms, including which joint venture partner provides the project manager; and (6) reviewing the funding and operating agreements. We analyze each joint venture initially to determine if it should be consolidated or unconsolidated into our financial statements: • A joint venture is consolidated into our financial statements if we are the primary beneficiary of a VIE or hold the majority of voting interests of a non-VIE (and no significant participative rights are available to the other partners). • A joint venture is not consolidated into our financial statements if we are not the primary beneficiary of a VIE, or do not hold the majority of voting interest of a non-VIE. We account for our unconsolidated joint ventures using the equity method of accounting. Under this method, we recognize our proportionate share of the net earnings of these joint ventures as “Equity in earnings (loss) of unconsolidated joint ventures”. Our maximum exposure to loss as a result of our investments in unconsolidated variable interest entities is typically limited to the aggregate of the carrying value of the investment and future funding commitments in these entities. 78 ESOP On May 8, 2019, we consummated the IPO. At the IPO date, shares held by the ESOP were subject to a 180-day lock-up period which concluded on November 3, 2019. We contribute shares of our own stock to the ESOP each year. Shares held by the ESOP or committed to be contributed to the ESOP were presented as temporary equity at December 31, 2018 as they included a cash redemption feature that was not solely within our control. At the conclusion of the 180-day lock-up period, ESOP distributions are no longer made in cash and are now made in shares of our common stock. Accordingly, at December 31, 2019, shares held by the ESOP were reclassified from temporary equity to permanent equity. Throughout the year, as employee services are rendered, we record compensation expense based on salaries of eligible employees. Contributions of our common stock to the ESOP are made annually in amounts determined by our board of directors and are held in trust for the sole benefit of the participants. Shares allocated to a participant’s account are fully vested after three years of credited service, or in the event(s) of reaching age 65, death or disability while an active employee. A participant’s interest in their ESOP account is redeemable upon certain events, including retirement, death, termination due to permanent disability, a severe financial hardship following termination of employment, certain conflicts of interest following termination of employment, or the exercise of diversification rights. Prior to the IPO, participants’ interests were redeemable in cash based on share prices established by the ESOP Trustee. Subsequent to the IPO and during the 180-day lock-up period, participants’ interests were redeemable in cash based on quoted prices of a share of our common stock on the NYSE. Subsequent to the 180-day lock-up period, distributions from the ESOP of participants’ interests are made in our common stock based on quoted prices of a share of our common stock on the NYSE. A participant will be able to sell such shares of common stock in the market, subject to any requirements of the federal securities laws. Valuation of Common Stock Prior to our IPO, our share price was determined using a combination of income- and market-based methods that utilized unobservable Level 3 inputs, including significant assumptions such as forecasted revenue and operating margins, working capital requirements and weighted average cost of capital. Given the absence of a public trading market for our common stock, for all purposes related to the fair market value of our common stock, we historically used the per share price of our common stock as established by the ESOP Trustee, taking into account, among other things, the advice of a third-party valuation consultant for the ESOP Trustee, as well as the ESOP Trustee’s knowledge of the Company as of December 31 for each calendar year. Subsequent to the IPO, the share price is based on quoted prices of the Company’s common stock on the NYSE. Equity-Based Compensation We measures the value of services received from employees and directors in exchange for an equity-based award based on the grant date fair value. We issue equity-based awards that settle in shares of our common stock. Prior to the IPO, we issued equity-based awards that settle in cash. Cash settled awards are subsequently remeasured to an updated fair value at each reporting period until the award is settled. Awards containing performance measures are adjusted at each reporting period for the number of shares expected to be earned. Compensation cost for cash settled and performance awards are trued-up at each reporting period for changes in fair value and expected shares pro-rated for the portion of the requisite service period rendered. We recognize compensation costs for these awards on either a straight-line or accelerated basis over the vesting period of the award in “Indirect, general and administrative expenses” in the consolidated statements of income. Self-Insurance We are self-insured for a portion of our losses and liabilities primarily associated with workers’ compensation, general, professional, automobile, employee matters, certain medical plans, and project specific 79 liability claims. Losses are accrued based upon our estimates of the aggregate liability for claims incurred using historical experience and certain actuarial assumptions, as provided by an independent actuary. The estimate of self-insurance liability includes an estimate of incurred but not reported claims, based on data compiled from historical experience. Recent Accounting Pronouncements See the information set forth in “Note 2—Summary of Significant Accounting Policies—Recently Adopted Accounting Pronouncements” in the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K. Off-Balance Sheet Arrangements As of December 31, 2020, we have no off-balance sheet arrangements that have or are reasonably likely to have a material current or future effect on our financial condition, changes in financial condition, revenue or expenses, results of operations, liquidity, capital expenditures or capital resources. Commitments and Contingencies We are subject to certain claims and assessments that arise in the ordinary course of business. Additionally, Parsons has been named as a defendant in lawsuits alleging personal injuries as a result of contact with asbestos products at various project sites. We believe that any significant costs relating to these claims will be reimbursed by applicable insurance and do not expect any of these claims to have a material adverse effect on our financial condition or results of operations. We record a liability when we believe that it is both probable that a loss has been incurred and the amount can be reasonably estimated. Management judgment is required to determine the outcome and the estimated amount of a loss related to such matters. Management believes that there are no claims or assessments outstanding which would materially affect our consolidated results of operations or our financial position. Item 7A. Qualitative and Quantitative Disclosure About Market Risk Interest Rate Risk We are exposed to interest rate risks related to our Revolving Credit Facility. As of December 31, 2020, we had no loan amounts outstanding under the Revolving Credit Facility. Borrowings under the Revolving Credit Facility bear interest, at our option, at either the Base Rate (as defined in the Credit Agreement), plus an applicable margin, or LIBOR plus an applicable margin. The applicable margin for Base Rate loans is a range of 0.125% to 1.00% and the applicable margin for LIBOR loans is a range of 1.125% to 2.00%, both based on the leverage ratio of the Company at the end of each fiscal quarter. The rates at December 31, 2020 and December 31, 2019 were 1.87% and 3.02%, respectively. Foreign Currency Exchange Risk We are exposed to foreign currency exchange rate risk resulting from our operations outside of the U.S. We limit exposure to foreign currency fluctuations in most of our contracts through provisions that require client payments in currencies corresponding to the currency in which costs are incurred. As a result of this natural hedge, we generally do not need to hedge foreign currency cash flows for contract work performed. Item 8. Financial Statements and Supplementary Data.

Evaluation of Disclosure Controls and Procedures Our management carried out, as of December 31, 2020, with the participation of our Chief Executive Officer and our Chief Financial Officer, an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2020, our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed by us in reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms and that information required to be disclosed by us in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Management’s Annual Report on Internal Control Over Financial Reporting Management is responsible for establishing and maintaining for the Company adequate internal control over financial reporting, as defined in Rule 13a-15(f) under the Exchange Act. Management, with the participation of its Chair and Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer), has assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2020 based on the framework established in “Internal Control—Integrated Framework,” issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on this assessment, management has concluded that the Company’s internal control over financial reporting was effective as of December 31, 2020. The Company’s independent registered public accounting firm, PricewaterhouseCoopers LLP, which audited the Company’s consolidated financial statements included in this Annual Report on Form 10-K, also audited the effectiveness of our internal control over financial reporting as of December 31, 2020, as stated in their audit report included in this Annual Report on Form 10-K. Changes in Internal Control Over Financial Reporting There have been no changes in our internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) of the Securities Exchange Act of 1934, that occurred during the quarter ended December 31, 2020 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

F-11 F-1 Report of Independent Registered Public Accounting Firm To the Board of Directors and Shareholders of Parsons Corporation Opinions on the Financial Statements and Internal Control over Financial Reporting We have audited the accompanying consolidated balance sheets of Parsons Corporation and its subsidiaries (the “Company”) as of December 31, 2020 and 2019, and the related consolidated statements of income, of comprehensive income, of changes in redeemable common stock and shareholders’ equity (deficit) and of cash flows for each of the three years in the period ended December 31, 2020, including the related notes and financial statement schedule listed in the index appearing under Item 15(a)(2) (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO. Changes in Accounting Principles As discussed in Note 2 to the consolidated financial statements, the Company changed the manner in which it accounts for leases in 2019 and the manner in which it accounts for revenue from contracts with customers in 2018. Basis for Opinions The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the Management’s Annual Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (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 audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated 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 consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. F-2 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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) 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 (iii) 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. Critical Audit Matters The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate. Revenue Recognition – Determination of Total Estimated Contract Cost and Variable Consideration related to Claims Revenue for Fixed-Price Contracts Recognized Over Time As described in Notes 2 and 4 to the consolidated financial statements, revenue is derived from long-term contracts with customers whereby the Company provides planning, design, engineering, technical, and construction and program management services. The Company enters into cost-plus, time-and-materials, and fixed-price contracts with its customers. Fixed-price contract revenue recognized was $1.3 billion for the year ended December 31, 2020, which accounts for approximately 32% of the Company’s total consolidated revenue. Fixed-price contract revenue is recognized over time using an input measure (i.e., costs incurred to date relative to total estimated costs at completion) to measure progress. Under the cost-to-cost measure of progress method, the extent of progress towards completion is measured based on the ratio of total costs incurred to-date to the total estimated costs at completion of the performance obligation. Revenues, including estimated fees or profits, are recorded proportionally as costs are incurred. Management includes variable consideration, such as claims revenue, in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. Contract costs consist of direct costs on contracts, including labor and materials, amounts payable to subcontractors, direct overhead costs and equipment expense (primarily depreciation, fuel, maintenance and repairs). Changes to estimated contract costs, either due to unexpected events or revisions to management’s initial estimates, for a given project are recognized in the period in which they are determined. As disclosed by management, recognition of profit on long-term contracts requires the use of assumptions and estimates related to total contract revenue and in particular estimated claims revenue, total estimated cost at completion, and the measurement of progress towards completion. Management’s estimates are continually evaluated as work progresses and are revised when necessary. F-3 The principal considerations for our determination that performing procedures relating to revenue recognition, specifically the determination of total estimated contract cost and variable consideration related to estimated claims revenue for fixed-price contracts recognized over time is a critical audit matter are (i) the significant amount of judgment by management in determining the total estimated contract cost and variable consideration related to estimated claims revenue for fixed-price contracts; (ii) a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating audit evidence for the total estimated contract cost and variable consideration related to estimated claims revenue for fixed-price contracts recognized over time. Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the revenue recognition process including controls over the determination of total estimated contract cost and variable consideration related to estimated claims revenue for fixed-price contracts recognized over time. These procedures also included, among others, for a selection of fixed-price contracts, (i) evaluating and testing management’s process for determining the total estimated contract cost and variable consideration related to estimated claims revenue, which included testing of contracts and other documents related to the estimates, and testing of underlying incurred and estimated contract costs; (ii) assessing management’s ability to reasonably estimate total contract costs by performing a comparison of the actual total estimated contract cost as compared with prior period estimates, including evaluating the timely identification of circumstances that may warrant a modification to the total estimated contract cost; and (iii) evaluating estimated claims revenue by inquiry with external legal counsel regarding the underlying claim and agreeing estimated claims revenue to documents related to those estimates. Acquisition of Braxton Science & Technology Group - Valuation of Customer Relationships Intangible Asset As described in Notes 2 and 3 to the consolidated financial statements, on November 19, 2020, the Company acquired a 100% ownership interest in Braxton Science & Technology Group (“Braxton”) for $310.9 million in cash, which resulted in $74.0 million of intangible assets being recorded, of which, $35.6 million related to customer relationships. Management accounts for business combinations using the acquisition method, under which the purchase price of an acquired company is allocated to the tangible and intangible assets acquired and the liabilities assumed on the basis of their fair values at the date of acquisition. The determination of fair values of assets acquired and liabilities assumed requires management to make estimates and use valuation techniques when a market value is not readily available. Management’s determination of the fair value of the intangible assets acquired involved the use of significant estimates and assumptions related to discount rates, revenue growth rates, projected margins, and customer revenue attrition rates. The principal considerations for our determination that performing procedures relating to the valuation of the customer relationships intangible asset acquired in the acquisition of Braxton Science & Technology Group is a critical audit matter are (i) the high degree of auditor judgment and subjectivity in performing procedures relating to the fair value measurement of the customer relationships intangible asset acquired due to the significant judgment by management when determining the fair value estimate; (ii) significant audit effort in performing procedures and evaluating management’s significant assumptions relating to the discount rate, revenue growth rate, projected margin, and customer revenue attrition rate; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge. Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the acquisition accounting, including controls over the significant assumptions used in management’s valuation of the customer relationships intangible asset. These procedures included, among others, (i) reading the purchase agreement; (ii) testing management’s process for estimating the fair value of the customer relationships intangible asset; (iii) evaluating the appropriateness of the valuation technique; (iv) testing the completeness and accuracy of the underlying data used in the valuation technique; and (v) evaluating the reasonableness of significant assumptions related to the discount rate, revenue growth rate, projected margin, and F-4 customer revenue attrition rate. Evaluating the reasonableness of management’s assumptions related to the revenue growth rate, projected margin and customer revenue attrition rate involved considering (i) the current and past performance of the acquired business; (ii) the consistency with external market and industry data; and (iii) whether these assumptions were consistent with evidence obtained in other areas of the audit. Professionals with specialized skill and knowledge were used to assist in the evaluation of management’s valuation technique and the discount rate significant assumption. /s/ PricewaterhouseCoopers LLP Los Angeles, California February 24, 2021 We have served as the Company’s auditor since at least 1969.

F-10 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 1. Description of Operations Organization Parsons Corporation, a Delaware corporation, and its subsidiaries (collectively, the “Company”) provide sophisticated design, engineering and technical services, and smart and agile software to the United States federal government and Critical Infrastructure customers worldwide. The Company performs work in various foreign countries through local subsidiaries, joint ventures and foreign offices maintained to carry out specific projects. Initial Public Offering On May 8, 2019, the Company consummated its initial public offering (“IPO”) whereby the Company sold 18,518,500 shares of common stock for $27.00 per share. The underwriters exercised their share option on May 14, 2019 to purchase an additional 2,777,775 shares at the share price of $25.515 which was the IPO share price of $27.00 less the underwriting discount of $1.485 per share. The net proceeds of the IPO and the underwriters’ share option were $536.9 million, after deducting underwriting discounts and other fees, and were used to fund an IPO dividend of $52.1 million, repay the outstanding balance of $150.0 million under our Term Loan, and repay outstanding indebtedness under our Revolving Credit Facility. Stock Dividend On April 15, 2019, the board of directors of the Company declared a common stock dividend in a ratio of two shares of common stock for every one share of common stock then held by the Company’s stockholder (the “Stock Dividend”). The record date of this common Stock Dividend was May 7, 2019, the day immediately prior to the consummation of the Company’s IPO on May 8, 2019, and the payment date of the Stock Dividend was May 8, 2019. Purchasers of the Company’s common stock in the Company’s public offering were not entitled to receive any portion of the Stock Dividend. 2. Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the accounts of Parsons Corporation and its subsidiaries and affiliates which it controls. Interests in joint ventures that are controlled by the Company, or for which the Company is otherwise deemed to be the primary beneficiary, are consolidated. For joint ventures in which the Company does not have a controlling interest, but exerts significant influence, the Company applies the equity method of accounting. Intercompany accounts and transactions are eliminated in consolidation. Use of Estimates The preparation of the consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from those estimates. The Company’s most significant estimates and judgments involve revenue recognition with respect to the determination of the costs to complete contracts and transaction price; determination of self-insurance reserves; useful lives of property and equipment and intangible assets; calculation of allowance for doubtful accounts; valuation of deferred income tax assets and uncertain tax positions, among others. F-11 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 ESOP The Company maintains a non-leveraged ESOP for eligible employees, for which the Company contributes shares of its own stock to the ESOP trust each year. Throughout the year, as employee services are rendered, the Company records compensation expense based on salaries of eligible employees. At each reporting period, the shares held within the ESOP or committed to be contributed to the ESOP are adjusted to their redemption value through an offsetting charge or credit to accumulated deficit. Treasury Stock The Company records treasury stock purchases under the cost method whereby the entire cost of the acquired stock is recorded as treasury stock. The Company records the reissuance of treasury stock using the first-in, first-out method of accounting. Contributions of 1,522,381 shares, 1,345,198 shares, and 1,874,988 shares of common stock were made to the ESOP in 2020, 2019 and 2018, respectively. In 2019 and 2018, the Company repurchased 191,331 shares, and 5,553,891 shares of common stock from the ESOP, respectively, in connection with the redemption of ESOP participants’ interests in the ESOP for $6.3 million and $125.8 million, respectively. Subsequent to November 3, 2019 when the 180-day lock-up period ended, repurchases are no longer required for ESOP redemptions. In 2020 the Company did not repurchase any shares of common stock. Earnings per Share Basic earnings per common share (“EPS”) is calculated by dividing Net income by the weighted average number of common shares outstanding during the year. Diluted earnings per common share is calculated by dividing net income by adjusted weighted average outstanding shares, assuming conversion of all potentially dilutive securities. Upon contribution to the ESOP, the shares become outstanding and are included within the earnings per share computations. Revenue Recognition On December 30, 2017, the Company adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, (“ASC 606”), using the modified retrospective method, which provides for a cumulative effect adjustment to retained earnings beginning in fiscal 2018 for those uncompleted contracts impacted by the adoption of the new standard. The difference between the recognition criteria under ASC-606 and our previous recognition practices under ASC 605-35 was recognized through a cumulative adjustment of $4.7 million that was made to the opening balance of accumulated deficit as of December 30, 2017. In accordance with ASC 606, the Company follows the five-step process in ASC 606 to recognize revenue: 1. 2. Identify the contract Identify performance obligations 3. Determine the transaction price 4. Allocate the transaction price 5. Recognize revenue Contracts—Revenue is derived from long-term contracts with customers whereby the Company provides planning, design, engineering, technical, and construction and program management services. The Company has contracts with the United States federal government that contain provisions requiring compliance with the United States Federal Acquisition Regulation (“FAR”) and the United States Cost Accounting Standards (“CAS”). These regulations are generally applicable to all of the Company’s federal government contracts and are partially F-12 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 or fully incorporated in some local and state agency contracts. Most of the Company’s federal government contracts are subject to termination at the convenience of the client. These contracts typically provide for reimbursement of costs incurred and payment of fees earned through the date of such termination. The Company enters into the following types of contracts with its customers: Cost-Plus—Under cost-plus contracts, the Company is reimbursed for allowable or otherwise defined costs incurred, plus a fee. The contracts may also include incentives for various performance criteria, including quality, timeliness, safety and cost-effectiveness. In addition, costs are generally subject to review by clients and regulatory audit agencies, and such reviews could result in costs being disputed as nonreimbursable under the terms of the contract. Time-and-Materials—Under time-and-materials contracts, hourly billing rates are negotiated and charged to clients based on the actual time spent on a project. In certain cases, these contracts may be subject to maximum contract values. In addition, clients reimburse actual out-of-pocket costs for materials and other direct incidental expenditures that are incurred in connection with the performance under the contract. Fixed-Price—The Company enters into two types of fixed-price contracts: firm fixed-price (“FFP”) and fixed-price per unit (“FPPU”). Under FFP contracts, clients pay an agreed fixed-amount negotiated in advance for a specified scope of work. Contract Costs—Contract costs consist of direct costs on contracts, including labor and materials, amounts payable to subcontractors, direct overhead costs and equipment expense (primarily depreciation, fuel, maintenance and repairs). All contract costs are recorded as incurred. Changes to estimated contract costs, either due to unexpected events or revisions to management’s initial estimates, for a given project are recognized in the period in which they are determined. Pre-contract costs are expensed as incurred unless they are expected to be recovered from the client, generate or enhance resources that will be used in satisfying performance obligations in the future and directly relate to an existing or anticipated contract. Costs to mobilize equipment and labor to a job site, prior to substantive work beginning (“mobilization costs”) are capitalized as incurred and amortized over the expected duration of the contract. Additionally, the Company may incur incremental costs to obtain certain contracts, such as selling and market costs, bid and proposal costs, sales commissions, and legal fees, certain of which can be capitalized if they are recoverable under the contract. Capitalized contract costs are included in other current assets on the consolidated balance sheets and were not material as of December 31, 2020 and December 31, 2019. Performance Obligations—A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in ASC 606. The transaction price of a contract is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. To the extent a contract is deemed to have multiple performance obligations, the Company allocates the transaction price of the contract to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. The Company determines the relative standalone selling price utilizing observable prices for the sale of the underlying goods or services. Contracts are considered to have a single performance obligation if the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts or is not distinct in the context of the contract, which is mainly because the Company provides a significant service of integrating a complex set of tasks and components into a single project or capability. Engineering and construction contracts are generally accounted for as a single performance obligation while our engineering and construction supervision contracts are accounted for as two separate performance obligations. When providing construction supervision services, the Company is not liable for the construction of the asset, but has an overall responsibility to oversee, coordinate, measure, and evaluate F-13 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 the quality of construction work and the performance of the construction contractor on behalf of the customer. Customers are generally billed as the Company satisfies its performance obligations and payment terms typically range from 30 to 120 days from the invoice date. Billings under certain fixed-price contracts may be based upon the achievement of specified milestones, while some arrangements may require advance customer payment. The Company’s contracts generally do not include a significant financing component. Variable Consideration—The transaction price for the Company’s contracts may include variable consideration, which includes increases to transaction price for approved and unpriced change orders, claims and incentives, and reductions to transaction price for liquidated damages. Change orders, claims and incentives are generally not distinct from the existing contract due to the significant integration service provided in the context of the contract and are accounted for as a modification of the existing contract and performance obligation. The Company estimates variable consideration for a performance obligation utilizing one of the two prescribed methods, depending on which method better predicts the amount of consideration to which the Company will be entitled (or the amount the Company expects to incur in the case of liquidated damages). Such methods are: (a) the expected value method, whereby the amount of variable consideration to be recognized represents the sum of probability weighted amounts in a range of possible consideration amounts, and (b) the most likely amount method, whereby the amount of variable consideration to be recognized represents the single most likely amount in a range of possible consideration amounts. When applying these methods, the Company considers all information that is reasonably available, including historical, current and estimates of future performance. The expected value method is utilized in situations where a contract contains a large number of possible outcomes, while the most likely amount method is utilized in situations where a contract has only two possible outcomes. The Company includes variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. The Company’s estimates of variable consideration and determination of whether to include estimated amounts in transaction price are based largely on an assessment of anticipated performance and all information (historical, current and forecasted) that is reasonably available. The effect of variable consideration on the transaction price of a performance obligation is recognized as an adjustment to revenue on a cumulative catch-up basis. Change Orders—Change orders, which are a normal and recurring part of business, may include changes in specifications or design, manner of performance, facilities, equipment, materials, sites and period of completion of the work. The Company or customer may initiate change orders. Most change orders are not distinct from the existing contract and are accounted for as part of that existing contract. The effect of a change order on the transaction price and measure of progress for the performance obligation to which it relates is recognized as an adjustment to revenues (either as an increase in or a reduction of revenues) on a cumulative catch-up basis. Revenues from unpriced change orders are recognized to the extent of the amounts the Company expects to recover, consistent with the variable consideration policy discussed above. If it is probable that a reversal of revenues will occur, the costs attributable to change orders are treated as contract costs without incremental revenues. To the extent change orders included in the price are not resolved in the Company’s favor, there could be reductions in, or reversals of previously reported amounts of, revenues and profits, and charges against current earnings, which could be material. Claims Revenue—Claims are amounts in excess of agreed contract prices that the Company seeks to collect from clients or others for customer-caused delays, errors in specifications and designs, contract terminations, change orders that are in dispute, or other causes of unanticipated additional contract costs, including factors outside of our control, and therefore the Company believes it is entitled to additional compensation. Claims revenue, when recorded, is only recorded to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. The Company includes certain claims in the transaction price when the claims F-14 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 are legally enforceable, the Company considers collection to be probable and believes it can reliably estimate the ultimate value. The Company continues to engage in negotiations with its customers on outstanding claims. However, these claims may be resolved at amounts that differ from current estimates, which could result in increases or decreases in future estimated contract profits or losses. Warranties—In most cases, contracts include assurance-type warranties that the Company’s performance is free from material defect and consistent with the specifications of the Company’s contracts, which do not give rise to a separate performance obligation. To the extent the warranty terms provide the customer with an additional service, such as extended maintenance services, such warranty is accounted for as a separate performance obligation. Revenue recognized over time—The Company’s performance obligations are generally satisfied over time as work progresses because of continuous transfer of control to the customer and the Company has the right to bill the customer as costs are incurred. Typically, revenue is recognized over time using an input measure (i.e.’ costs incurred to date relative to total estimated costs at completion) to measure progress. The Company generally uses the cost-to-cost measure of progress method because it best depicts the transfer of control to the customer which occurs as the Company incurs costs on its contracts. Under the cost-to-cost measure of progress method, the extent of progress towards completion is measured based on the ratio of total costs incurred to-date to the total estimated costs at completion of the performance obligation. Revenues, including estimated fees or profits, are recorded proportionally as costs are incurred. Any expected losses on construction-type contracts in progress are charged to earnings, in total, in the period the losses are identified. The Company recognizes adjustments in estimated profit on contracts under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance is recognized using the adjusted estimate. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, the Company recognizes the total loss in the period it is identified. Right to invoice practical expedient—For performance obligations satisfied over time where the Company has a right to consideration from a customer in an amount that corresponds directly with the value of the Company’s performance to-date, the Company recognizes revenue in the amount to which it has a right to invoice. For the Company’s reimbursable services contracts, revenue is recognized using the right to invoice practical expedient, or on a cost-to-cost measure of progress method. The Company will select the method that best represents progress on a project. Revenue recognized at a point in time—For performance obligations satisfied at a point in time, revenue is recognized when the services are performed, control is transferred, and the performance obligation is complete. The Company recognizes revenue at a point in time for vehicle inspection services. Revenue related to the inspection service is recognized for each vehicle inspection at the point the Company has completed the inspection. In the Company’s industry, recognition of profit on long-term contracts requires the use of assumptions and estimates related to total contract revenue and in particular estimated claims revenue, total estimated cost at completion, and the measurement of progress towards completion. Estimates are continually evaluated as work progresses and are revised when necessary. When a change in estimate is determined to have an impact on contract profit, the Company records a positive or negative adjustment to the consolidated statements of income. Refer to the Recently Adopted Accounting Pronouncements for discussion of the differences between the current revenue recognition criteria under ASC 606 and the Company’s previous recognition practices under ASC 605, Revenue Recognition. F-15 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 Cash Equivalents The Company considers all highly liquid investments with original maturities of less than three months to be cash equivalents. Cash equivalent investments are carried at cost, which approximates fair value, and consist primarily of United States Treasuries, time deposits, and other forms of short-term fixed income investments. Restricted Cash and Investments Restricted cash and investments held in trust accounts represent collateral for certain incentive programs. Accounts Receivable, Net Accounts receivable includes billed and unbilled amounts and are recognized in the period when the Company’s rights to receive consideration are unconditional. The Company establishes an allowance for doubtful accounts based on consideration of trends in actual and forecasted credit quality of clients, including delinquency and payment history, type of client, such as a government agency or commercial sector client, and general economic conditions and particular industry conditions that may affect a client’s ability to pay. Past due receivable balances are written off when internal collection efforts have been unsuccessful in collecting the amounts due. Contract Assets and Contract Liabilities Projects with performance obligations recognized over time that have revenue recognized to-date in excess of cumulative billings and unbilled accounts receivable are reported on our consolidated balance sheets as “Contract assets”. Contract retentions, included in contract assets, represent amounts withheld by clients, in accordance with underlying contract terms, until certain conditions are met or the project is completed. The operating cycle for certain long-term contracts may extend beyond one year, and, accordingly, collection of retainage on those contracts may extend beyond one year. Contract assets are reclassified to accounts receivable when the right to consideration becomes unconditional. Contract liabilities on uncompleted contracts represent the excess of cash collected from clients and billings to clients on contracts in advance of work performed over the amount of revenue recognized and provisions for losses. The majority of these amounts are expected to be earned within 12 months and are classified as current liabilities. Concentration of Credit Risk Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivables. The Company’s cash is primarily held with major banks and financial institutions throughout the world. At times, cash balances may be in excess of the amount insured. The Company is involved in a significant volume of contracts with the United States federal government and state and local governments. Approximately 49%, 48%, and 42% of consolidated revenues for the years ended December 31, 2020, December 31, 2019 and December 31, 2018, respectively, and approximately 19% and 18% of accounts receivable as of December 31, 2020 and December 31, 2019, respectively, were derived from contracts with the United States federal government. No other customers represented 10% or more of consolidated revenues or accounts receivable in any of the periods presented. F-16 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 In order to mitigate the credit risk associated with customers, the Company performs periodic credit evaluations of its customers’ financial condition. Property and Equipment Property and equipment are stated at cost and are shown net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. Depreciation of leasehold improvements is computed using the straight-line method over the shorter of their estimated useful lives or the remaining term of the lease. The cost of assets retired or otherwise disposed of and the related accumulated depreciation are eliminated from the accounts, and any gain or loss thereon is included in net income. Expenditures for maintenance and repairs are expensed as incurred. Property and equipment are reviewed for impairment when events or circumstances change that indicate they may not be recoverable. Impairment losses are recognized when estimated future cash flows expected to result from the use of the assets and their eventual disposition are less than their carrying amount, in which case the asset is written down to its fair value. Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease ROU assets and current and long-term operating lease liabilities in the consolidated balance sheets. Finance leases are included in other noncurrent assets, accrued expenses and other current liabilities and other long-term liabilities in the consolidated balance sheets. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit rate, incremental borrowing rates are used based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term. We have lease agreements with lease and non-lease components where the lease consideration is allocated between the components based on relative standalone prices. For real property leases, allocations of lease consideration between lease and non-lease components are immaterial. For certain equipment leases, such as vehicles, we account for the lease and non-lease components as a single lease component. Additionally, for certain equipment leases, we apply a portfolio approach to effectively account for the operating lease ROU assets and liabilities. Equity-Based Compensation The Company measures the value of services received from employees and directors in exchange for an equity-based award based on the grant date fair value. The Company issues equity-based awards that settle in shares of the Company’s common stock. Prior to the IPO, the Company issued equity-based awards that settled in cash. Cash settled awards are subsequently remeasured to an updated fair value at each reporting period until the award is settled. Awards containing performance measures are adjusted at each reporting period for the number of shares expected to be earned. Compensation cost for cash settled and performance awards are trued-up at each reporting period for changes in fair value and expected shares pro-rated for the portion of the requisite F-17 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 service period rendered. The Company recognizes compensation costs for these awards on either a straight-line or accelerated basis over the vesting period of the award in indirect, general and administrative expense in the consolidated statements of income. Business Combinations The Company accounts for business combinations using the acquisition method, under which the purchase price of an acquired company is allocated to the tangible and intangible assets acquired and the liabilities assumed on the basis of their fair values at the date of acquisition. Any excess of purchase price over the fair value of tangible and intangible assets acquired and liabilities assumed is allocated to goodwill. The determination of fair values of assets acquired and liabilities assumed requires the Company to make estimates and use valuation techniques when a market value is not readily available. The Company’s determination of the fair value of the intangible assets acquired involves the use of significant estimates and assumptions related to discount rates, revenue growth rates, projected margins, and customer revenue attrition rates. The Company adjusts the preliminary purchase price allocation, as necessary, during the measurement period of up to one year after the acquisition closing date as the Company obtains more information as to facts and circumstances existing at the acquisition date. Acquisition-related costs are recognized separate from the acquisition and are expensed as incurred. Consolidation of Joint Ventures and Variable Interest Entities The Company participates in joint ventures, which include partnerships and partially owned limited liability corporations, to bid, negotiate and complete specific projects. The Company is required to consolidate these joint ventures if it holds the majority voting interest or if the joint venture is determined to be a variable interest entity (“VIE”) for which the Company is the primary beneficiary, as described below. A VIE is an entity with one or more of the following characteristics: (a) the total equity investment at risk is not sufficient to permit the entity to finance its activities without additional financial support; (b) as a group, the holders of the equity investment at risk lack the ability to make certain decisions, the obligation to absorb expected losses or the right to receive expected residual returns; or (c) an equity investor has voting rights that are disproportionate to its economic interest and substantially all of the entity’s activities are on behalf of the investor with disproportionately low voting rights. The Company’s VIEs may be funded through contributions, loans and/or advances from the joint venture partners or by advances and/or letters of credit provided by clients. Certain VIEs are directly governed, managed, operated and administered by the joint venture partners. Others have no employees and, although these entities own and hold the contracts with the clients, the services required by the contracts are typically performed by the joint venture partners or by other subcontractors. The Company is considered the primary beneficiary and required to consolidate a VIE if it has the power to direct the activities that most significantly impact that VIE’s economic performance, and the obligation to absorb losses or the right to receive benefits of that VIE that could potentially be significant to the VIE. In determining whether the Company is the primary beneficiary, significant assumptions and judgments include the following: (1) identifying the significant activities and the parties that have the power to direct them; (2) reviewing the governing board composition and participation ratio; (3) determining the equity, profit and loss ratio; (4) determining the management-sharing ratio; (5) reviewing employment terms, including which joint venture partner provides the project manager; and (6) reviewing the funding and operating agreements. Examples of significant activities currently being performed by the Company’s significant consolidated and unconsolidated F-18 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 joint ventures include engineering and design services; management consulting services; procurement and construction services; program management; construction management; and operations and maintenance services. If the Company determines that the power to direct the significant activities is shared by two or more joint venture parties, then there is no primary beneficiary and no party consolidates the VIE. In making the shared-power determination, the Company analyzes the key contractual terms, governance, related party and de facto agency as they are defined in the accounting standard, and other arrangements. Goodwill In 2019, the Company changed the date of its annual goodwill impairment testing from November 30 to October 1. This change results in better alignment of the Company’s annual impairment test with the Company’s annual budgeting cycle and provides a more reliable measurement using the Company’s interim closing processes. The change had no effect on the Company’s financial statements for the current or historical periods. The Company performs an additional review at year end to address whether a triggering event has occurred that would require an interim impairment test in the interim period. For purposes of impairment testing, goodwill is allocated to the applicable reporting units based on the current reporting structure. The Company’s reporting units are operating segments or components of operating segments where discrete financial information is available and segment management regularly reviews the operating results. When evaluating goodwill for impairment, the Company may decide to first perform a qualitative assessment, or “step zero” impairment test, to determine whether it is more likely than not that impairment has occurred. If the Company does not perform a qualitative assessment, or if the Company determines that it is not more likely than not that the fair value of its reporting units exceeds their carrying amounts, the Company performs a quantitative assessment and calculates the estimated fair value of the respective reporting unit. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized in the amount the carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The Company’s decision to perform a qualitative impairment assessment in a given year is influenced by a number of factors, including the significance of the excess of the Company’s estimated fair value over carrying value at the last quantitative assessment date, the amount of time in between quantitative fair value assessments, and the date of its acquisitions, if any. Intangible Assets Intangible assets with finite lives arise from business acquisitions and are amortized based on the period over which the contractual or economic benefit of the intangible assets are expected to be realized or on a straight-line basis over the useful lives of the underlying assets, ranging from one to ten years. These primarily consist of customer relationships, developed technology, backlog, and covenants not to compete. When indicators of a potential impairment exist, the Company assesses the recoverability of the unamortized balance of its intangible assets by first comparing undiscounted expected cash flows associated with the asset, or the asset group they are part of, to its carrying value. Should the review indicate that the carrying value is not fully recoverable, the excess of the carrying value over the fair value of the intangible assets would be recognized as an impairment loss. Income Taxes Income taxes are accounted for under the asset and liability method. This approach requires the recognition of deferred tax liabilities and assets to reflect the tax effects of temporary differences between the financial F-19 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 statement carrying amounts and tax bases of the Company’s assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. Deferred tax assets are evaluated for future realization and valuation allowances are established when, in our opinion, it is more likely than not that all or some portion of the asset will not be realized. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements on a particular tax position are measured based on the largest benefit that is greater than 50 percent likely of being realized. The amount of unrecognized tax benefits (“UTB”) is adjusted as appropriate for changes in facts and circumstances, such as significant amendments to existing tax law, new regulations or interpretations by the taxing authorities, new information obtained during a tax examination, or resolution of an examination. The Company recognizes both accrued interest and penalties, where appropriate, related to UTBs in income tax expense. Foreign Currency Translation The Company’s reporting currency is the U.S. Dollar. The functional currency of the Company’s foreign entities is typically the currency of the primary environment in which they operate. For foreign entities whose functional currency is not the U.S. dollar, the assets and liabilities are translated based on exchange rates in effect at the balance sheet date, while the income and expense accounts are translated using the average exchange rates during the period. Translation gains or losses, net of income tax effects, are reflected in accumulated other comprehensive income on the consolidated balance sheets. Transaction gains and losses due to movements in exchange rates between the functional currency and the currency in which a foreign currency transaction is denominated are recognized as “Other income (expense), net” in the Company’s consolidated statements of income. Self-Insurance The Company typically utilizes third-party insurance subject to varying retention levels or self-insurance. The Company is self-insured for a portion of the losses and liabilities primarily associated with workers’ compensation, general, professional, automobile, employee matters, certain medical plans, and project-specific liability claims. Losses are accrued based upon the Company’s estimates of the aggregate liability for claims incurred using historical experience and certain actuarial assumptions, as provided by an independent actuary. The estimate of self-insurance liability includes an estimate of incurred but not reported claims, based on data compiled from historical experience. Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, “Leases (Topic 842)”, which is a new standard related to leases intended to increase transparency and comparability among organizations by requiring the recognition of right-of-use (“ROU”) assets obtained in exchange for lease liabilities on the balance sheet. Most prominent among the changes in the standard is the recognition of ROU assets and lease liabilities by lessees for those leases classified as operating leases. Under the standard, disclosures are required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The Company elected to adopt the standard, and available practical expedients, effective January 1, 2019. These practical expedients allowed the Company to keep the lease classification assessed under the previous F-20 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 lease accounting standard (ASC 840) without reassessment under the new standard, and allowed all separate lease components, including non-lease components, to be accounted for as a single lease component for all existing leases prior to adoption of the new standard. Furthermore, the Company made an accounting policy election to not recognize a lease liability and ROU asset for leases with lease terms of twelve months or less. The Company adopted this new standard under the modified retrospective transition approach without adjusting comparative periods in the financial statements, as allowed under Topic 842, and implemented internal controls and key system functionality to enable the preparation of financial information on adoption. The standard had a material impact on the Company’s consolidated balance sheets but did not have an impact on the consolidated statements of income and cash flows. The most significant impact was the recognition of ROU assets and lease liabilities for operating leases, while accounting for finance leases remained substantially unchanged. As a result of the adoption, the Company recorded a cumulative-effect adjustment to retained earnings of $52.6 million, net of deferred tax asset adjustment of $0.7 million, representing the unamortized portion of a deferred gain previously recorded as a sale-leaseback transaction associated with the sale of an office building in 2011. The Company concluded the transaction resulted in the transfer of control of the office building to the buyer-lessor at market terms and would have qualified as a sale under Topic 842 with gain recognition in the period the sale was recognized. In July 2018, the FASB issued ASU No. 2018-09, “Codification Improvements”. The amendments in this ASU clarify certain aspects of the guidance related to: reporting comprehensive income, debt modification and extinguishment, income taxes related to stock compensation, income taxes related to business combinations, derivatives and hedging, fair value measurements, brokers and dealers liabilities, and plan accounting. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company has adopted this ASU on a prospective basis in the first quarter of 2019 and has determined there to be no impact on its financial statements and related disclosures. Effective January 1, 2019, the Company adopted ASU 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” under which the Company did not elect to reclassify the income tax effects stranded in accumulated other comprehensive income to retained earnings as a result of the enactment of comprehensive tax legislation, commonly referred to as the Tax Cuts and Jobs Act. As a result, there was no impact on the Company’s financial position, results of operations or cash flows. In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” and issued subsequent amendments to the initial guidance within ASU 2019-04 and ASU 2019-05. The amendments in ASU 2016-13 replace the incurred loss impairment methodology in current practice with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to estimate credit losses. ASU 2016-13 and its amendments are effective for interim and annual reporting periods beginning after December 15, 2019. The Company adopted this ASU in the first quarter of 2020, and it did not have a material impact on its financial statements. Recently Issued Accounting Pronouncements In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”)”. ASU 2019-12 was issued as a means to reduce the complexity of accounting for income taxes for those entities that fall within the scope of the accounting standard. The guidance is to be applied using a prospective method, excluding amendments related to franchise taxes, which F-21 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 should be applied on either a retrospective basis for all periods presented or a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. ASU 2019-12 is effective for fiscal years beginning after December 15, 2020, with early adoption permitted. The Company did not elect to adopt early and it does not expect this standard to have a material impact on its consolidated financial statements. In August 2020, the FASB issued ASU 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40). The update simplifies the accounting for convertible debt instruments and convertible preferred stock by reducing the number of accounting models and limiting the number of embedded conversion features separately recognized from the primary contract. The guidance also includes targeted improvements to the disclosures for convertible instruments and earnings per share. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. The Company will early adopt this standard in 2021 using the modified retrospective method and expects it will result in a reduction in non-cash interest expense and a reclassification of the equity portion of the Convertible Senior Notes to liabilities on the consolidated balance sheet. 3. Acquisitions Polaris Alpha On May 31, 2018, the Company acquired a 100% ownership interest in Polaris Alpha, a privately-owned, advanced technology-focused provider of innovative mission solutions for complex defense, intelligence, and security customers, as well as other U.S. federal government customers, for $489.1 million paid in cash. The Company borrowed $260 million under the Credit Agreement, as described in “Note 12—Debt and Credit Facilities”, to partially fund the acquisition. In connection with this acquisition, the Company recognized $6.2 million of acquisition-related expenses in “Indirect, general and administrative expense” in the consolidated statements of income for the year ended December 31, 2018, including legal fees, consulting fees, and other miscellaneous direct expenses associated with the acquisition. Polaris Alpha enhances the Company’s artificial intelligence and data analytics expertise with new technologies and solutions. Customers of both companies will benefit from existing, complementary technologies and increased scale, enabling end-to-end solutions under the shared vision of rapid prototyping and agile development.

Unbilled accounts receivable represents amounts where the Company has a present contractual right to bill but an invoice has not been issued to the customer at the period-end date. In connection with the adoption of ASU 2016-13, we have modified the historical presentation of gross receivables and the allowance for doubtful accounts to reflect only expected credit losses in the allowance in conformity with the current period presentation. The allowance for doubtful accounts was determined based on consideration of trends in actual and forecasted credit quality of clients, including delinquency and payment history, type of client, such as a government agency or commercial sector client, and general economic conditions and particular industry conditions that may affect a client’s ability to pay. COVID-19 Impacts: We have not seen and do not expect there to be a material risk of non-payment from either our government agency or commercial customers. We have experienced payment delays due to administrative limitations from both types of customers. F-29 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 Transaction Price Allocated to the Remaining Unsatisfied Performance Obligations The Company’s remaining unsatisfied performance obligations (“RUPO”) as of December 31, 2020 represent a measure of the total dollar value of work to be performed on contracts awarded and in progress. The Company had $5.2 billion in RUPO as of December 31, 2020. RUPO will increase with awards of new contracts and decrease as the Company performs work and recognizes revenue on existing contracts. Projects are included within RUPO at such time the project is awarded and agreement on contract terms has been reached. The difference between RUPO and backlog relates to unexercised option years that are included within backlog and the value of Indefinite Delivery/Indefinite Quantity (“IDIQ”) contracts included in backlog for which task orders have not been issued.

Employee Stock Purchase and Equity-Based Compensation Plans Employee Stock Purchase Plan The Parsons Corporation Employee Stock Purchase Plan (“ESPP”) was adopted effective March 1, 2020. Under the ESPP, eligible employees who elect to participate are granted the right to purchase shares of Parsons common stock at a discount of 5% of the market value on the last trading day of the offering period. The following table presents stock issuance activity for the year ended December 31, 2020 (in thousands): Purchase price paid for shares sold . . . . . . . . . . . . . . . . . . . . . . Number of shares sold . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2020 $4,386 127 The average purchase price for the year ended December 31, 2020 was $34.53 per share. Equity-Based Compensation Plans The Company issues stock-based awards through the Shareholder Value Plan, Long-Term Growth Plan, Restricted Award Plan, and Incentive Award Plan. Through these plans the Company may issue stock options (including incentive and non-qualified stock options), stock appreciation rights, restricted stock, restricted stock units, an “other” stock or cash-based awards, or a dividend equivalent award. The compensation expense for these awards is recorded in “Indirect, general and administrative expenses” in the Company’s consolidated financial statements. Stock-based compensation expense was $7.3 million, $49.0 million, and $16.3 million for the years ended December 31, 2020, December 31, 2019 and December 31, 2018, respectively, net of recognized tax benefits of $2.5 million, $16.7 million, and $0.2 million for 2020, 2019 and 2018, respectively. The tax benefit realized related to awards vested during 2020, 2019, and 2018 was $11.2 million, $3.3 million, and $0.2 million, respectively. We recognize forfeitures as they occur. With the adoption of the Incentive Award Plan on April 15, 2019, the Company has discontinued issuing awards under the other plans described above. Outstanding awards granted out of the discontinued plans will continue to vest and will settle in cash. At December 31, 2020, the amount of compensation cost relating to non-vested awards not yet recognized in the consolidated financial statements is $16.5 million. The majority of these unrecognized compensation costs will be recognized by the third quarter of fiscal 2021. As discussed in “Note 1—Description of Operations”, the Company consummated its IPO on May 8, 2019. Subsequent to the IPO, the fair value of a share of the Company’s common stock is based on quoted prices on the NYSE. Please see “Note 19—Fair Value of Financial Instruments” for a description of how the fair value of a share of the Company’s common stock was determined prior to the IPO. Stock Appreciation Rights Stock Appreciation Rights (“SARs”) were issued under the Shareholder Value Plan (“SVP”). Outstanding awards provide a cash incentive based on the increase in the Company’s share price over a three-year period, F-32 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 multiplied by a number of phantom share units. If at the end of a performance cycle the Company’s share price has not increased, then no award payment will be made. The awards issued under the SVP are time-vested cash- settled SARs. The SARs vest at the end of three years and expense is recognized on an accelerated basis over the vesting period. The grant date fair value of the award is determined by using the Black-Scholes option-pricing model. SARs are remeasured, using the Black-Scholes option-pricing model, to an updated fair value at each reporting period until the award is settled. The fair value of the grant on the vesting date is determined based on the 60-trading day weighted average closing price of the Company’s common stock on the NYSE. Compensation cost is trued-up at each reporting period for changes in fair value pro-rated for the portion of the requisite service period rendered. The final SVP grant vested on December 31, 2020 based on the 60-trading day weighted average closing price of the Company’s common stock on the NYSE. Therefore, the Black-Scholes option-pricing model was not used as of December 31, 2020. The following table presents the number of SARs granted, vested, and forfeited for the years ended December 31, 2018, December 31, 2019, and December 31, 2020: Unvested at December 29, 2017 . . . . . . . . . . .

Sale-Leasebacks During fiscal 2011, the Company consummated two sale-leaseback transactions associated with the sale of two office buildings from which the Company recognized a total gain in the consolidated statements of income of $106.7 million and a total deferred gain of $107.8 million. The current and long-term portion of the deferred gain had been recorded in “Accrued expenses and other current liabilities” and “Deferred gain resulting from sale-leaseback transactions” on the consolidated balance sheet as of December 31, 2018, respectively, and was being recognized ratably over the minimum lease terms to which they relate, as an offset to rental expense in “Indirect, general and administrative expenses” in the consolidated statements of income. Amortization of the deferred gain was $7.3 million for the year ended December 31, 2018. The deferred gain balance of $53.3 million as of December 31, 2018 was recognized as an adjustment to beginning accumulated deficit, net of a deferred tax asset adjustment of $0.7 million, during January 2019 in connection with the adoption of the new leasing standard.

The Company incurred approximately $2.0 million of costs in connection with this amendment. Under the agreement, the Company’s revolving credit facility was increased from $500 million to $550 million and the term of the agreement was extended through November 2022. The borrowings under the Credit Agreement bear interest, at the Company’s option, at either the Base Rate (as defined in the Credit Agreement), plus an applicable margin, or LIBOR plus an applicable margin. The applicable margin for Base Rate loans is a range of 0.125% to 1.00% and the applicable margin for LIBOR loans is a range of 1.125% to 2.00%, both based on the leverage ratio of the Company at the end of each fiscal quarter. The rates at December 31, 2020 and December 31, 2019 were 1.87% and 3.02%, respectively. Borrowings under this Credit Agreement are guaranteed by certain of the Company’s operating subsidiaries. Letters of credit commitments outstanding under this agreement aggregated approximately $44.9 million and $43.7 million at December 31, 2020 and December 31, 2019, respectively, which reduced borrowing limits available to the Company. Interest expense related to the Credit Agreement was $1.0 million, $6.3 million and $6.1 million, for the years ended December 31, 2020, December 31, 2019 and December 31, 2018, respectively. There were no loan amounts outstanding under the Credit agreement at December 31, 2020. F-39 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 Term Loan In January 2019, the Company borrowed $150.0 million under our Term Loan Agreement to partially finance the OGSystems acquisition. On May 10, 2019, the Company used proceeds from its May 8, 2019 IPO to repay the $150.0 million outstanding balance under the Term Loan and this loan is now closed. Interest expense related to the Term Loan was $2.3 million for the year ended December 31, 2019. There were no amounts outstanding in 2020. Private Placement On July 1, 2014, the Company finalized a private placement whereby the Company raised an aggregate amount of $250.0 million in debt repayable as follows (in thousands): Tranche Debt Amount Maturity Date Interest Rate Senior Note, Series A . . . . . . . . . . . . . . . . . . .

On August 10, 2018, the Company finalized an amended and restated intercreditor agreement related to this private placement to more closely align certain covenants and definitions with the terms under the 2017 amended and restated Credit Agreement and incurred approximately $0.5 million of additional issuance costs. These costs are presented as a direct deduction from the debt on the face of the balance sheet. Interest expense related to the Senior Notes approximated $12.4 million for the years ended December 31, 2020, December 31, 2019 and December 31, 2018. The amortization of debt issuance costs and interest expense is recorded in “Interest expense” on the consolidated statements of income. The Company made interest payments related to the Senior Notes of approximately $12.4 million during the years ended December 31, 2020, December 31, 2019 and December 31, 2018. Interest payable of approximately $5.5 million and $5.7 million was recorded in “Accrued expenses and other current liabilities” on the consolidated balance sheets at December 31, 2020 and December 31, 2019, respectively, related to the Senior Notes. The Credit Agreement and private placement includes various covenants, including restrictions on indebtedness, liens, acquisitions, investments or dispositions, payment of dividends and maintenance of certain financial ratios and conditions. The Company was in compliance with these covenants at December 31, 2020 and December 31, 2019. The Company also has in place several secondary bank credit lines for issuing letters of credit, principally for foreign contracts, to support performance and completion guarantees. Letters of credit commitments outstanding under these bank lines aggregated approximately $193.1 million and $197.3 million at December 31, 2020 and December 31, 2019, respectively. Using a discounted cash flow technique that incorporates a market interest yield curve with adjustments for duration, optionality, and risk profile, the Company estimated the fair value (Level 2) of its senior notes at December 31, 2020 approximates $275.0 million. See “Note 19—Fair Value of Financial Instruments” for the definition of level 2 of the fair value hierarchy below. F-40 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 Convertible Senior Notes In August 2020, the Company issued an aggregate $400.0 million of 0.25% Convertible Senior Notes due 2025, including the exercise of a $50.0 million initial purchasers’ option. The Company received proceeds from the issuance and sale of the Convertible Senior Notes of $389.7 million, net of $10.3 million of transaction fees and other third-party offering expenses. The Convertible Senior Notes accrue interest at a rate of 0.25% per annum, payable semi-annually on February 15 and August 15 of each year beginning on February 15, 2021, and will mature on August 15, 2025, unless earlier repurchased, redeemed or converted. The Convertible Senior Notes are the Company’s senior unsecured obligations and will rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to any of the Company’s unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of the Company’s secured indebtedness, to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of the Company’s subsidiaries Each $1,000 of principal of the Notes will initially be convertible into 22.2913 shares of our common stock, which is equivalent to an initial conversion price of $44.86 per share, subject to adjustment upon the occurrence of specified events. On or after March 15, 2025 until the close of business on the second scheduled trading day immediately preceding the maturity date of the Convertible Senior Notes, holders may convert all or a portion of their Convertible Senior Notes, regardless of the conditions below. Prior to the close of business on the business day immediately preceding March 15, 2025, the Notes will be convertible at the option of the holders thereof only under the following circumstances: • • • • during any calendar quarter commencing after the calendar quarter ending on December 31, 2020, if the last reported sale price of the Company’s common stock for at least 20 trading days, whether or not consecutive, during a period of 30 consecutive trading days ending on, and including the last trading day of the immediately preceding calendar quarter, is greater than or equal to 130% of the conversion price on each applicable trading day; during the five business day period after any five consecutive trading day period in which, for each trading day of that period, the trading price per $1,000 principal amount of Convertible Senior Notes for such trading day was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; if the Company calls such Convertible Senior Notes for redemption; or upon the occurrence of specified corporate events described in the Indenture. The Company may redeem all or any portion of the Convertible Senior Notes for cash, at its option, on or after August 21, 2023 and before the 51st scheduled trading day immediately before the maturity date at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, but only if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price for a specified period of time. In addition, calling any Convertible Senior Note for redemption will constitute a Make-Whole Fundamental Change with respect to that Convertible Senior Note, in which case the conversion rate applicable to the conversion of that Convertible Senior Note will be increased in certain circumstances if it is converted after it is called for redemption. Upon the occurrence of a fundamental change prior to the maturity date of the Convertible Senior Notes, holders of the Convertible Senior Notes may require the Company to repurchase all or a portion of the F-41 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 Convertible Senior Notes for cash at a price equal to 100% of the principal amount of the Convertible Senior Notes to be repurchased, plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date. Upon conversion, the Company may settle the Convertible Senior Notes for cash, shares of the Company’s common stock, or a combination thereof, at the Company’s option. If the Company satisfies its conversion obligation solely in cash or through payment and delivery of a combination of cash and shares of the Company’s common stock, the amount of cash and shares of common stock due upon conversion will be based on a daily conversion value calculated on a proportionate basis for each trading day in a 50-trading day observation period. Convertible debt instruments that may be settled in cash on conversion are required to be separated into liability and equity components in a manner that reflects the issuer’s non-convertible debt borrowing rate. The carrying amount of the liability component is based on the fair value of a similar instrument that does not contain an equity conversion option. The carrying amount allocated to the equity component, which is recognized as a debt discount, represents the difference between the proceeds from the issuance of the notes and the fair value of the liability component of the notes. Based on this debt to equity ratio, debt issuance costs are then allocated to the liability and equity components in a similar manner. Accordingly, at issuance the Company allocated $336.1 million to the debt liability and $53.6 million to additional paid-in capital. The difference between the principal amount of the Convertible Senior Notes and the liability component, inclusive of issuance costs, represents the debt discount, which the Company amortizes to interest expense over the term of the Convertible Senior Notes using an effective interest rate of 3.25%. During the year ended December 31, 2020, the Company recognized interest expense of $4.4 million related to the amortization of debt discount and issuance costs. As of December 31, 2020, the net carrying value of the Notes was $340.6 million. A summary as of December 31, 2020 of the gross carrying amount, unamortized debt discount including debt issuance costs, and net carrying value of the liability component of the Convertible Senior Notes is as follows: Par value . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Under the five-year term of the bond hedge, upon a conversion of the bonds, the Company will receive the number of shares of common stock equal to the remaining common stock deliverable upon conversion of the Convertible Senior Notes if the conversion value exceeds the principal amount of the Notes. The aggregate number of shares that the Company could be obligated to issue upon conversion of the Convertible Senior Notes is approximately 8.9 million shares. The cost of the convertible note hedge transactions was $55.0 million. The cost of the convertible note hedge was partially offset by the Company’s sale of warrants to acquire approximately 8.9 million shares of the Company’s common stock. The warrants were initially exercisable at a price of at least $66.46 per share and are subject to customary adjustments upon the occurrence of certain events, such as the payment of dividends. The Company received $13.8 million in cash proceeds from the sales of these warrants. F-42 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 The bond hedge and warrant transactions effectively increased the conversion price associated with the Convertible Senior Notes during the term of these transactions from 35%, or $44.86, to 100%, or $66.46, at their issuance, thereby reducing the dilutive economic effect to shareholders upon actual conversion. The bond hedges and warrants are indexed to, and potentially settled in, shares of the Company’s common stock. The net cost of $41.2 million for the purchase of the bond hedges and sale of the warrants was recorded as a reduction to additional paid-in capital in the consolidated balance sheets. At issuance, the Company recorded a deferred tax liability of $16.2 million related to the Convertible Senior Notes debt discount and a deferred tax asset of $16.5 million related to the convertible note hedge transactions. The deferred tax liability and deferred tax asset are included net in “Deferred tax assets” on the consolidated balance sheets 13.

Income Taxes Historically, the Company had elected to be taxed under the provisions of Subchapter “S” of the Internal Revenue Code for federal tax purposes. As a result, income was not subject to U.S. federal income taxes or state income taxes in those states where the “S” Corporation status is recognized. Therefore, previously, no provision or liability for federal or state income tax had been provided in the consolidated financial statements except for those states where the “S” Corporation status was not recognized, or where states imposed a tax on “S” Corporations. The provision for income tax in the historical periods prior to the IPO consists of these state taxes and taxes from certain foreign jurisdictions where the Company is subject to tax. In connection with the Company’s IPO on May 8, 2019, the “S” Corporation status was terminated, and the Company is now treated as a “C” Corporation under the Internal Revenue Code. The termination of the “S” Corporation status was treated as a change in tax status under Accounting Standards Codification 740, Income Taxes. These rules require that the deferred tax effects of a change in tax status to be recorded to income from continuing operations on the date the “S” Corporation status terminates. The termination of the “S” Corporation election has had a material impact on the Company’s results of operations, financial condition, and cash flows as reflected in the December 31, 2020 and December 31, 2019 consolidated financial statements. Income tax expense decreased in 2019 primarily due to a tax benefit recorded for the revaluation of our deferred tax assets and liabilities as a result of our conversion from “S” Corporation to a “C” Corporation. The effective tax rate has increased, and net income has decreased as compared to the Company’s “S” Corporation tax years, since the Company is now subject to both U.S. federal and state corporate income taxes on its earnings. F-43 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted in response to the COVID-19 pandemic. The CARES Act, among other things, permits Net Operating Loss (“NOL“) carryovers to offset 100% of taxable income for tax years beginning before 2021. In addition, the CARES Act allows NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding tax years to generate a refund of previously paid income taxes. The CARES Act contains modifications on the limitation of business interest for tax years beginning in 2019 and 2020. The modifications to Section 163(j) increase the allowable business interest deduction from 30% of adjusted taxable income to 50% of adjusted taxable income. The CARES Act also accelerates the refund of alternative minimum tax (“AMT”) credits that were previously accumulated. The Company does not expect that the modifications on the limitation of business interest or AMT credits would have any impact to the Company. Under the NOL carryback provision, the Company carried back some of its NOLs claiming a tax refund of $3.9 million relating to certain amounts associated with the acquisition of OGSystems which are subject to certain shareholders’ claims. On July 9, 2020, the U.S. Treasury Department issued final tax regulations related to the foreign-derived intangible income (“FDII”) and global intangible low-taxed income (“GILTI”) provisions. Also, on July 20, 2020 the U.S. Treasury Department released final tax regulations permitting a taxpayer to elect to exclude from its GILTI inclusion items of income subject to a high effective rate of foreign tax. Additionally, on August 21, 2020, the U.S. Treasury Department finalized anti-abuse regulations limiting deductions of foreign-source dividends. Separately, on September 2, 2020, the U.S. Treasury Department finalized regulations on the base erosion anti- abuse tax under IRC Section 59A. The U.S. Treasury Department also finalized a second set of regulations on the allowance for the additional first-year depreciation deduction under IRC Section 168(k) on September 16, 2020, as amended by the Tax Cuts and Jobs Act (“TCJA”), for qualified property acquired and placed in service after September 27, 2017. Further, on September 29, 2020, the U.S. Treasury Department issued final tax regulations addressing various aspects of the foreign tax credit regime. Lastly, on December 21, 2020, the U.S. Treasury Department released final regulations addressing the timing of income recognition for accrual method taxpayers under IRC Sections 451(b) and 451(c), as amended by the 2017 TCJA. The Company is currently assessing the impact of the new regulations to its consolidated financial statements but does not expect a material change of its income tax expense due to the new regulations.

The change in the effective tax rate was due primarily to the nonrecurring tax benefit items included in 2019 for the remeasurement of its U.S. deferred tax assets and liabilities due to the change in tax status from an S Corporation to a C Corporation. The effective tax rate for the year ended December 31, 2020 differs from the federal statutory tax rate primarily due to state income taxes and a recorded valuation allowance on foreign tax credits, partially offset by benefits related to income attributable to noncontrolling interest and federal research tax credits.

The Company considers all negative and positive evidence, including the weight of the evidence, to determine if a valuation allowance against deferred tax assets is required. A valuation allowance is recorded against deferred tax assets to reflect the amount of deferred tax assets that is determined to be more-likely- than-not to be realized. The tax cost, net of applicable credits, has been provided on the undistributed earnings of the Company’s foreign subsidiaries. The Company does not assert any earnings to be permanently reinvested. As of December 31, 2020, and December 31, 2019, the Company’s valuation allowance against deferred tax assets is $23.9 million and $17.4 million, respectively. This valuation allowance represents the portion of deferred tax assets primarily related to foreign net operating loss carryforwards, foreign tax credit carryforwards and capital loss carryforwards for which the Company has determined are not more-likely-than-not to be realized. From December 31, 2019 to December 31, 2020, the Company’s valuation allowance increased by $6.5 million. Of this increase, $6.9 million relates to deferred tax assets recorded for foreign tax credit carryforwards offset in part by decrease in valuation allowance related to net operating loss carryforwards. The valuation allowance is generated because the Company does not and will not have sufficient foreign source income to support the foreign tax credit carryforwards. As of December 31, 2020, the Company has NOLs of $32.8 million, and $36.7 million for U.S. states and foreign jurisdictions, respectively. The utilization of the U.S. state NOLs are subject to certain annual limitations. Of these amounts, $27.0 million and $33.9 million in U.S. states and foreign jurisdictions, respectively, do not expire. The remaining amounts of NOLs in U.S. states and in foreign jurisdictions will expire if not used between 2021 and 2041. F-46 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 As of December 31, 2020, the Company has foreign tax credit carryforwards of $15.5 million. The Company has provided a valuation allowance of $15.5 million as the Company considers that these credits will not be realized. These foreign tax credits start expiring in the year 2029.

The Company recognizes interest and penalties related to unrecognized tax benefits as part of its income tax expense. During the years ended December 31, 2020, December 31, 2019, and December 31, 2018, the Company recognized approximately $1.1 million, $1.3 million, and $0.0 million in interest and penalties, respectively for each year, in the Consolidated Statements of Income. The total amount of interest and penalties accrued in the Consolidated Balance Sheets was $4.4 million, $3.4 million, and $2.0 million at December 31, 2020, December 31, 2019, and December 31, 2018, respectively. The Company conducts business globally and, as a result, the Company or one or more of its subsidiaries file income tax returns in the U.S. federal jurisdiction, various U.S. states, and foreign jurisdictions. The Company is subject to examination by tax authorities in several jurisdictions, including major jurisdictions such as Canada, Mexico, Qatar, Saudi Arabia and the United States. As of December 31, 2020, the Company’s U.S. federal income tax returns for tax years 2017 and forward remain subject to examination. U.S. states and foreign income tax returns remain subject to examination based on varying local statutes of limitations. The Company estimates that, within 12 months, it may decrease its uncertain tax positions by approximately $0.3 million as a result of concluding various tax audits and closing tax years. Although the Company believes its reserves for its tax positions are reasonable, the final outcome of tax audits could be significantly different, both favorably and unfavorably. It is reasonably possible that these audits may conclude in the next 12 months and that the unrecognized tax benefits the Company has recorded in relation to these tax years may change compared to the liabilities recorded for these periods. However, it is not currently possible to estimate the amount, if any, of such change. 15. Contingencies The Company is subject to certain lawsuits, claims and assessments that arise in the ordinary course of business. Additionally, the Company has been named as a defendant in lawsuits alleging personal injuries as a result of contact with asbestos products at various project sites. Management believes that any significant costs relating to these claims will be reimbursed by applicable insurance and, although there can be no assurance that F-47 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 these matters will be resolved favorably, management believes that the ultimate resolution of any of these claims will not have a material adverse effect on our consolidated financial position, results of operations, or cash flows. A liability is recorded when it is both probable that a loss has been incurred and the amount of loss or range of loss can be reasonably estimated. When using a range of loss estimate, the Company records the liability using the low end of the range. The Company records a corresponding receivable for costs covered under its insurance policies. Management judgment is required to determine the outcome and the estimated amount of a loss related to such matters. Management believes that there are no claims or assessments outstanding which would materially affect the consolidated results of operations or the Company’s financial position. On or about March 1, 2017, the Peninsula Corridor Joint Powers Board, or the JPB, filed a lawsuit against Parsons Transportation Group, Inc., or PTG, in the Superior Court of California, County of San Mateo, in connection with a positive train control project on which PTG was engaged prior to termination of its contract by the JPB. PTG had previously filed a lawsuit against the JPB for breach of contract and wrongful termination. The JPB seeks damages in excess of $100.0 million, which the Company is currently disputing. In addition to filing a complaint for breach of contract and wrongful termination, the Company has denied the allegations raised by the JPB and, accordingly, filed affirmative defenses. The Company is currently defending against the JPB’s claims and the parties are still engaged in discovery. The Company also has a professional liability insurance policy to the extent the JPB proves any errors or omissions occurred. At this time, the Company is unable to determine the probability of the outcome of the litigation or determine a potential range of loss, if any. The Company has also filed a third-party claim against a subcontractor for indemnification in connection with this matter. In September 2015, a former Parsons employee filed an action in the United States District Court for the Northern District of Alabama against us as a qui tam relator on behalf of the United States (the “Relator”) alleging violation of the False Claims Act. The United States government did not intervene in this matter as it is allowed to do so under the statute. The Company filed a motion to dismiss the lawsuit on the grounds that the Relator did not meet the applicable statute of limitations. The District Court granted the motion to dismiss. The Relator’s attorney appealed the decision to the United States Court of Appeals of the Eleventh Circuit, which ultimately ruled in favor of the Relator, and the Company petitioned the United States Supreme Court to review the decision. The Supreme Court reviewed the decision and accepted the position of the Relator. The case was thus remanded to the United States District Court for the Northern District of Alabama. The defendants, including Parsons, will file appropriate pleadings opposing the allegations. At this time, the Company is unable to determine the probability of the outcome of the litigation or determine a potential range of loss, if any. On or about October 4, 2019, LBH Engineers, LLC (“LBH”) filed a lawsuit against Parsons, PTG, and various other parties in the US District Court of for the Northern District of Georgia, in connection with an alleged infringement of LBH’s patent. LBH seeks damages and costs incurred by LBH, a post-judgment royalty and treble damages if the infringement is found to be willful, among other damages, which the Company and the other defendants are currently disputing. At this time, the Company is unable to determine the probability of the outcome of the litigation or determine a potential range of loss, if any. Federal government contracts are subject to audits, which are performed for the most part by the Defense Contract Audit Agency (“DCAA”). Audits by the DCAA and other agencies consist of reviews of our overhead rates, operating systems and cost proposals to ensure that we account for such costs in accordance with the Cost Accounting Standards (“CAS”). If the DCAA determines we have not accounted for such costs in accordance with the CAS, the DCAA may disallow these costs. The disallowance of such costs may result in a reduction of revenue and additional liability for the Company. Historically, the Company has not experienced any material disallowed costs as a result of government audits. However, the Company can provide no assurance that the DCAA or other government audits will not result in material disallowances for incurred costs in the future. All audits of costs incurred on work performed through 2010 have been closed, and years thereafter remain open. F-48 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 Although there can be no assurance that these matters will be resolved favorably, management believes that their ultimate resolution will not have a material adverse impact on the Company’s consolidated financial position, results of operations, or cash flows. 16. Retirement and Other Benefit Plans The Company’s principal retirement benefit plan is the ESOP, a stock bonus plan, established in 1975 to cover eligible employees of the Company and certain affiliated companies. Contributions of treasury stock to ESOP are made annually in amounts determined by the Company’s board of directors and are held in trust for the sole benefit of the participants. Shares allocated to a participant’s account are fully vested after six years of credited service, or in the event(s) of reaching age 65, death or disability while an active employee of the Company. As of December 31, 2020, the total shares of the Company’s common stock outstanding were 102,360,662, of which 76,641,312 were held by the ESOP. As of December 31, 2019, the total shares of the Company’s common stock outstanding were 100,669,694, of which 78,896,806 were held by the ESOP. A participant’s interest in their ESOP account is redeemable upon certain events, including retirement, death, termination due to permanent disability, a severe financial hardship following termination of employment, certain conflicts of interest following termination of employment, or the exercise of diversification rights. Distributions from the ESOP of participants’ interests are made in the Company’s common stock based on quoted prices of a share of the Company’s common stock on the NYSE. A participant will be able to sell such shares of common stock in the market, subject to any requirements of the federal securities laws. Total ESOP contribution expense was approximately $55.3 million, $55.5 million and $45.2 million for the years ended December 31, 2020, December 31, 2019 and December 31, 2018, respectively, and is recorded in “Direct costs of contracts” and “Indirect, general and administrative expense” in the consolidated statements of income. On April 3, 2019, the board of directors of the Company declared a cash dividend to the Company’s sole existing shareholder at that time, the ESOP, in the amount of $2.00 per share, or $52.1 million in the aggregate (the “IPO Dividend”). The IPO Dividend was paid on May 10, 2019. On April 15, 2019, the board of directors of the Company declared the Stock Dividend in a ratio of two shares of common stock for every one share of common stock then held by the Company’s shareholder. The record date of the Stock Dividend was May 7, 2019, the day immediately prior to the consummation of the Company’s IPO on May 8, 2019, and the payment date of the Stock Dividend was May 8, 2019. Purchasers of the Company’s common stock in the Company’s public offering were not entitled to receive any portion of the Stock Dividend. During the years ended December 31, 2020 and December 31, 2018, the Company did not declare any dividends. The Company also maintains a defined contribution plan (the “401(k) Plan”). Substantially all domestic employees are entitled to participate in the 401(k) Plan, subject to certain minimum requirements. The Company’s contributions to the 401(k) Plan for the years ended December 31, 2020, December 31, 2019 and December 31, 2018 amounted to $24.4 million, $25.2 million, and $17.1 million, respectively. As part of an acquisition in 2014, the Company acquired a defined contribution pension plan, a defined benefit pension plan, and supplemental retirement plan. For the defined contribution pension plan, the Company contributes a base amount plus an additional amount based upon a predetermined formula. At December 31, 2020 and December 31, 2019, the defined benefit pension plan was in a net asset position of $2.0 million and $2.1 million, respectively, which is recorded in “Other noncurrent assets” on the consolidated balance sheets. F-49 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 17. Investments in and Advances to Joint Ventures The Company participates in joint ventures to bid, negotiate and complete specific projects. The Company is required to consolidate these joint ventures if it holds the majority voting interest or if the Company meets the criteria under the consolidation model, as described below. The Company performs an analysis to determine whether its variable interests give the Company a controlling financial interest in a VIE for which the Company is the primary beneficiary and should, therefore, be consolidated. Such analysis requires the Company to assess whether it has the power to direct the activities of the VIE and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. The Company analyzed all of its joint ventures and classified them into two groups: (1) joint ventures that must be consolidated because they are either not VIEs and the Company holds the majority voting interest, or because they are VIEs and the Company is the primary beneficiary; and (2) joint ventures that do not need to be consolidated because they are either not VIEs and the Company holds a minority voting interest, or because they are VIEs and the Company is not the primary beneficiary. Many of the Company’s joint venture agreements provide for capital calls to fund operations, as necessary; however, such funding is infrequent and is not anticipated to be material. Letters of credit outstanding described in ‘Note 12—Debt and Credit Facilities” that relate to project ventures are approximately $59.3 million and $55.0 million at December 31, 2020 and December 31, 2019, respectively. In the table below, aggregated financial information relating to the Company’s joint ventures is provided because their nature, risk and reward characteristics are similar. None of the Company’s current joint ventures that meet the characteristics of a VIE are individually significant to the consolidated financial statements. Consolidated Joint Ventures The following represents financial information for consolidated joint ventures included in the consolidated financial statements as of and for the years ended December 31, 2020, December 31, 2019 and December 31, 2018 (in thousands): 2020 2019 Current assets . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

See “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this Annual Report on Form 10-K for a description of this matter, which was resolved in favor of the Company on June 13, 2018. Unconsolidated Joint Ventures The Company accounts for its unconsolidated joint ventures using the equity method of accounting. Under this method, the Company recognizes its proportionate share of the net earnings of these joint ventures as “Equity in earnings (loss) of unconsolidated joint ventures” in the consolidated statements of income. The Company’s maximum exposure to loss as a result of its investments in unconsolidated VIEs is typically limited to the aggregate of the carrying value of the investment and future funding commitments. The following represents the financial information of the Company’s unconsolidated joint ventures as presented in their unaudited financial statements as or and for the years ended December 31, 2020 and December 31, 2019 (in thousands): 2020 2019 Current assets . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Fair Value of Financial Instruments The authoritative guidance on fair value measurement defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (referred to as an “exit price”). At December 31, 2020 and December 31, 2019, the Company’s financial instruments include cash, cash equivalents, accounts receivable, accounts payable, and other liabilities. The fair values of these financial instruments approximate their carrying values due to their short-term maturities. Investments measured at fair value are based on one or more of the following three valuation techniques: • Market approach—Prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities; • Cost approach—Amount that would be required to replace the service capacity of an asset (i.e., replacement cost); and • Income approach—Techniques to convert future amounts to a single present amount based on market expectations (including present value techniques, option-pricing models and lattice models). In addition, the guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted market prices in active markets for identical assets and liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are: Level 1 Unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets and liabilities; Level 2 Pricing inputs that include quoted prices for similar assets and liabilities in active markets and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the derivative instrument; and Level 3 Prices or valuations that require inputs that are both significant to the fair value measurements and unobservable. The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or F-52 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

At December 31, 2020 and December 31, 2019, the Company measured the mutual funds held within the defined benefit pension plan at fair value using unadjusted quoted prices in active markets that are accessible for identical assets. The Company measured the fixed income securities using market bid and ask prices. The inputs that are significant to the valuation of fixed income securities are generally observable, and therefore have been classified as Level 2. The following table sets forth redeemable common stock associated with the ESOP in “Note 16— Retirement and Other Benefits Plans” that is accounted for at fair value by Level within the fair value hierarchy.

Prior to the conclusion of the 180-day lock-up period, all shares held by the ESOP were redeemable in the future for cash at the option of the holder once vesting and eligibility requirements had been met. At December 31, 2018, 78,172,809 shares of the Company’s common stock were held by the ESOP which the Company recorded at their redemption values of $1.9 billion and presented as temporary equity on the consolidated balance sheet. The redemption value was based on a share price established by the ESOP trustee, taking into account, among other things, the advice of a third-party valuation consultant for the ESOP trustee, as well as the ESOP trustee’s knowledge of the Company. The share price valuation was determined using a combination of income- and market-based methods that utilized unobservable Level 3 inputs, including significant assumptions such as forecasted revenue and operating F-53 PARSONS CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2020, December 31, 2019 and December 31, 2018 margins, working capital requirements, and weighted average cost of capital. At December 31, 2019, all outstanding shares of common stock are included in permanent equity in the consolidated balance sheet.

Like all option-pricing models, the Black-Scholes option-pricing model requires the use of subjective assumptions, including (i) the expected volatility of the market price of the underlying stock, and (ii) the expected term of the award, among others. Accordingly, changes in assumptions and any subsequent adjustments to those assumptions can cause different fair values to be assigned to SARs. Fair value for cash settled awards (excluding SARs prior to vesting) is determined based on the 60-trading day weighted average closing price of the Company’s common stock on the NYSE at the end of each reporting period and on the vesting date. For restricted stock units containing service conditions or service and performance conditions, fair value is based on the closing stock price of a share of the Company’s common stock on the NYSE on the grant date. 20. Earnings Per Share The tables below reconcile the denominator and numerator used to compute basic earnings per share (“EPS”) to the denominator and numerator used to compute diluted EPS for the years ended December 31, 2020, December 31, 2019 and December 31, 2018. Basic EPS is computed using the weighted average number of shares outstanding during the period and income available to shareholders. Diluted EPS is computed similar to basic EPS, except the income available to shareholders is adjusted to add back interest expense, after tax related to the Convertible Senior Note, and the weighted average number of shares outstanding is adjusted to reflect the dilutive effects of equity-based awards and shares underlying the Convertible Senior Note. Convertible Senior Note dilution impact is calculated using the if-converted method which will be required upon adoption of ASU 2020-06. As a result, the Company elected to adopt the if-converted method under the present accounting. In connection with the offerings of our note, the Company entered into a convertible note hedge and warrants (see Note 12 Debt and Credit Facilities); however, the convertible note hedge is not considered when calculating dilutive shares given its impact is anti-dilutive. The impact of the bond hedge would offset the dilutive impact of the shares underlying the Convertible Senior Note. The warrants have a strike price above our average share price during the period and are out of the money and not included in the tables below. Dilutive potential common shares include, when circumstances require, shares the Company could be obligated to issue from its Convertible Senior Notes and warrants (see Note 12 for further discussion) and equity- based awards. Shares to be provided to the Company from its bond hedge purchased concurrently with the issuance of Convertible Senior Notes are anti-dilutive and are not included in its diluted shares. Anti-dilutive equity-based awards excluded from the calculation of earnings per share for the years ended December 31, 2020 and December 31, 2019 were 5,327 and 0, respectively.

Excluding the claim settlement, revenue for the year ended December 31, 2018 for the Critical Infrastructure segment was $2.0 billion and for the Mobility Solutions revenue business line revenue was $1.5 billion. Effective January 1, 2020, the Company made changes to its business lines as described below. The prior year information in the table above has been reclassified to conform to the business line changes. Federal Solutions Business Line Changes As a result of the acquisitions of Polaris Alpha, OGSystems and QRC, we realigned the five business lines within our Federal Solutions segment into four business lines. We consolidated all space and geospatial programs from the former Geospatial Solutions, Defense and Cyber & Intelligence markets into a new Space & Geospatial Solutions business line to increase focus on the critical, evolving space market. This new business line better aligns capabilities and customers to drive growth and performance execution through improved agile, end-to-end solutions and dedicated customer focus. Further, we re-named our Defense business line to Missile Defense & C5ISR. We moved our Missions Solutions business line into our Missile Defense & C5ISR, Engineered Systems and Cyber & Intelligence business lines, for better customer and capability alignment. These changes were the next logical step in our acquisition integration process, to optimize performance delivery and growth.
