•
other risks and factors listed under “Risk Factors” and elsewhere in this report. 
We have based the forward-looking statements contained in this report primarily on our current expectations and projections about 
future events and trends that we believe may affect our business, financial condition, results of operations, prospects, business strategy and 
financial needs. The outcome of the events described in these forward-looking statements is subject to risks, uncertainties, assumptions and 
other factors described in the section captioned “Risk Factors” and elsewhere in this report. These risks are not exhaustive. Other sections of 
this report include additional factors that could adversely impact our business and financial performance. Furthermore, new risks and 
uncertainties emerge from time to time and it is not possible for us to predict all risks and uncertainties that could have an impact on the 
forward-looking statements contained in this report. We cannot assure you that the results, events and circumstances reflected in the 
forward-looking statements will be achieved or occur, and actual results, events or circumstances could differ materially from those described 
in the forward-looking statements. 
In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These 
statements are based upon information available to us as of the date of this report, and while we believe such information forms a reasonable
basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have 
conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain, 
and investors are cautioned not to unduly rely upon these statements. 
You should read this report and the documents that we reference in this report and have filed as exhibits to the registration statement 
of which this report forms a part with the understanding that our actual future results, levels of activity, performance and achievements may 
be materially different from what we expect. We qualify all of our forward-looking statements by these cautionary statements. 
The forward-looking statements made in this report relate only to events as of the date on which such statements are made. We 
undertake no obligation to update any forward-looking statements after the date of this report or to conform such statements to actual results 
or revised expectations, except as required by law.

 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 growth drivers in both our Federal Solutions and Critical Infrastructure segments.
Defense Spending Remains a Priority of the U.S. 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 cyber, space, artificial 
intelligence, electronic warfare, missile defense, and critical infrastructure protection. In addition, as a result of supporting ongoing war 
efforts, ammunition and munitions need to be replenished and the Army ammunition plants must be modernized to support this need. 
Cyber is Mission Critical to U.S. National Security and cyber adversaries 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. Additionally, there has 
been an increase in aggressive nation state cyber activity. Attacks by cyber-criminals seeking financial gain are also growing in volume and 
sophistication. We believe that the cyber market will continue to grow in response to the nation state threat landscape and the vulnerabilities 
inherent in critical infrastructure. Our unique portfolio of Federal Solutions and Critical Infrastructure provides the technical capabilities to 
detect and prevent cyberattacks along with the domain knowledge to understand how to secure infrastructure from threats.  Additionally, the 
United States must remain on the leading edge of cyber operations, platforms and tool development.
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.
Indo-Pacific is the Department of Defense’s Priority Theater. The United States has an enduring commitment to uphold a free and 
open Indo-Pacific region. This has become complicated due to inter-state strategic competition and increasingly complex security 
environment. The United States is focused on competing, deterring and winning in this environment to safeguard free and open international 
order.

Global Infrastructure Needs Significant Replacements and Technology-Driven Upgrades. Physical infrastructure is in need of 
upgrade throughout the world and there is unprecedented spend. Furthermore, modernized infrastructure is important to recover from 
unexpected disasters caused by climate change. The $1.2 trillion United States Infrastructure Investment and Jobs Act (IIJA) has increased 
funding for roads and highways, bridges, rail and transit, and aviation. Additionally, there is significant demand in other regions, including 
Canada and the Middle East. The Middle East has a planned spend that exceeds $1.5 trillion per the Middle East Economic Digest and 
Canada has invested $140 billion through the Investing in Canada Plan launched in 2016 for a 12-year period. In particular, the Saudi Vision 
2030 focus is driving major industrial city and urban development projects. Critical infrastructure, specifically transportation infrastructure that 
is essential to national economic and security concerns, is also vulnerable to cyber threats. We believe that a focus on safety, security, 
sustainability and environmental impacts will continue to drive replacement of aging infrastructure. 
Per- and Polyfluoroalkyl Substances (PFAS) Remediation. PFAS are manufactured chemicals that have been used in industry and 
consumer products since the 1940s. Scientific studies have shown that exposure to PFAS in the environment may be linked to harmful health 
effects in humans and animals. Therefore, there is a need to reduce PFAS in the environment – groundwater, soil, and surface water. The 
Environmental Protection Agency has taken actions, including $10 billion of funding to address emerging contaminants in the IIJA, issuing 
health advisories and proposing new, legally enforceable Maximum Contaminant Levels for PFAS substances found in drinking water. 
Parsons has unique capabilities, expertise, and experience to mitigate PFAS risks and liabilities for federal, state, and commercial 
customers.
Urbanization Creates Demand for Smart Cities with Connected Populations. Cities around the globe increasingly demand 
connected and 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 and Digital Transformation. 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 global customers. Across a broad set of industries, 
we provide smart and agile solutions that create the future for our national security and critical infrastructure customers as they adapt to the 
rapid changes of a more interconnected and technology-driven world.

Mergers and Acquisitions
We continue to pursue the acquisition and integration of high growth, technology driven companies which meet the following criteria: 
•
Financial performance goals: >10% top line growth, >10% Adjusted EBITDA margin, and strong cash flow
•
Align to our six focused markets  
•
Technology differentiation: fill technology gaps, drive end-to-end solutions, move up the value chain, scale within and across our 
businesses and add valuable intellectual property rights 
Our objective is to continue to transform our business into an integrated, full life-cycle solutions 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. Unfunded backlog 
does not include potential task orders expected to be awarded under multiple awards IDIQ contract vehicles, where task orders 
are competitively awarded and separately priced.
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. 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, 2024, our total backlog was approximately $8.9 billion, consisting of $5.9 billion of funded backlog and $3.0 billion 
of unfunded backlog. We expect to recognize $3.9 billion of our funded backlog as of December 31, 2024 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 governmental and commercial customers. We compete on the basis of our technical expertise, 
technological innovation, our ability to deliver cost-effective multi-faceted solutions and services in a timely manner, our reputation and 

 
16
relationships with our customers, qualified and/or security-clearance personnel, and pricing. Our peer group in Federal Solutions are U.S. 
federal systems integrators and service providers such as Booz Allen Hamilton, CACI International Inc, Leidos Holdings, Inc., and Science 
Applications International Corporation. Our peer group in Critical Infrastructure includes AECOM, Jacobs Solutions Inc., Stantec, Tetra Tech, 
Inc., and WSP.
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. 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 and aim to do this through providing a positive 
employee experience. 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. 
Our professionals are highly educated, with a wide range of technical acumen and in-depth domain knowledge and expertise. Our 
culture and values enable us to continue attracting qualified talent, particularly those with security clearances and requisite skills in multiple 
areas, including Project Management, Engineering, Software Development, Cyber, Data Analytics, Environmental and Architecture. We have 
over 10,300 employees who hold degrees and 3,300 with advanced degrees and professional credentials as of December 31, 2024. Our 
experienced teams understand our clients and are comprised of technology subject matter experts and professionals with deep knowledge 
and experience. 
Engagement
We pulse our workforce annually through an employee engagement survey and the data these surveys provide help us identify areas 
where our culture is evolving and key strategic areas where we need to continue to focus our energies to improve employee engagement 
and the employee experience. This data is critical in guiding our cultural journey to become a more dynamic, entrepreneurial, and creative 
place to work.
This year, we saw some of our highest participation rates among our business groups and functions, with an overall response of 60 
percent, which is higher than last year’s overall rate of 54 percent. We are also pleased that our employee engagement score was 80 against 
a benchmark of 75, up from 78 in 2023. At the highest level, our results describe an organization with a strong performance-driven and team-
based culture.
Employee Recognition
As a people first organization, we are dedicated to recognizing employee performance and promoting a culture of recognition. We are 
immensely proud to maintain a formal employee recognition program that is 100% developed and maintained in-house – a rare 
accomplishment in our industry. We approach company culture this way: recognition is a mindset.
The Distinguished Recognition and Incentive Program, affectionately known as the DRIVE Program, recognizes, rewards, and 
encourages high-caliber work. The DRIVE program is comprised of nine distinct 

 
17
award levels, each with its own criteria, workflow, and rewards – some monetary and some non-monetary. The program is open to all part- 
and full-time employees around the globe, and awards can be distributed from supervisor to team or team member, individual contributor to 
supervisor, and from peer to peer. That flexibility is what we are most proud of—all employees can recognize someone else or be recognized 
themself. In 2024, we are pleased that over 4,500 DRIVE awards were conveyed to our employees with monetary awards totaling over $7.5 
million.
Mentoring
Parsons has a robust mentoring program that facilitates several types of pairings, including senior leaders and employees, peer-to-
peer, veterans-to-veterans, and early career professionals with more experienced employees. Employees choose their own mentor and work 
closely with them to design a mentoring relationship that is tailored to meet their unique goals. Resources are provided to both mentors and 
mentees to ensure a successful and enriching experience for both. Most Parsons’ Vice Presidents and above are available and engaged in 
mentoring relationships thus actively fostering a culture of employee growth and development.
Career Development 
•
Parsons Learning Series – This program is open to all employees and consists of live, virtual one-hour courses across a wide 
range of topics appealing to both employees and managers. One or two topics are delivered each month. The live sessions are 
held at three separate times on the same day to accommodate our global workforce, and sessions are recorded and made 
available following live session dates.
•
Engaged Leadership Program (ELP) – This 4-month, cohort-based program helps people and project managers develop their 
management and leadership skills through learning about and then applying new skills on the job. The extended nature of this 
program fosters a collaborative environment and builds cross-organizational relationships among participants.
•
Intentional Leadership Program (ILP) – This is a program for senior leaders, Director-level and above. Participants will complete 
a facilitated 2-day curriculum designed to strengthen senior leadership skills and help participants intentionally define their own 
leadership approach while fostering cross-organizational communication and relationship-building.
•
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 fifty 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.
•
Technical Career Path - demonstrates two distinct career progressions for technical employees across our organization: one 
that follows a management path, the other that can be followed as an individual contributor. The Technical Career Path coupled 
with an integrated competency model and Workday tools such as the Opportunity Graph are resources designed to improve the 
quality of manager-employee career discussions and, ultimately, career movement.
Employee Stock Ownership Plan
At December 31, 2024, approximately 6,600 of our employees participated in our Employee Stock Ownership Plan (ESOP) which held 
54,117,904 shares at December 31, 2024. Our employees own approximately 40% of the total outstanding shares in the ESOP. 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 

 
18
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 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. In April 2022, the board of directors approved an amendment providing for lump sum distributions to participants and removing the 
annual installments. Annual diversification elections and five-year vested termination distributions are not impacted by this amendment and 
will still occur annually and over installments as outlined in the Plan.
Employee Stock Purchase Plan
At the 2020 Annual Meeting of Parsons’ Shareholders, the shareholders approved the implementation of the Employee Stock 
Purchase Plan (ESPP). The ESPP provides an opportunity for eligible employees (as defined in the ESPP) to purchase Parsons’ stock. By 
participating in the ESPP, an eligible employee may purchase Parsons’ shares at a 5% discount from the New York Stock Exchange closing 
price at the end date for each offering period (June 30th and December 31st of each year). During 2024 and 2023, our employees purchased 
approximately 95,984 and 116,650 shares, respectively, of Parsons’ stock.
Stock Repurchase Plan
On August 9, 2021, the board of directors authorized Parsons Corporation to acquire a number of shares of common stock having an 
aggregate market value of not greater than $100,000,000 from time to time, commencing on August 12, 2021. In August 2022, the Board 
amended the stock repurchase program and authorized executive management to determine an acceptable price for repurchasing such 
shares. The Board authorized management to execute any agreements providing for the repurchase of the Company’s stock, subject to such 
conditions, on behalf of the company in such lots, blocks or other amounts, from such persons or entities, from such sources, on the open 
market, in privately negotiated transactions, or otherwise, on such terms and conditions, from time to time, in accordance with applicable 
federal and state regulations. The Board further amended this authorization in February 2024 to restore the repurchase capacity to $100 
million and removed the $25 million quarterly cap on such repurchases. At the time of the February 2024 authorization, the Company had 
repurchased shares with an aggregated market value (including fees) of $54.7 million. The aggregate market value of shares of Common 
Stock the Company is authorized to acquire, from both the August 2021 and February 2024 authorizations, is not greater than $154.7 million. 
As of December 31, 2024, the company had repurchased 1,713,481 shares of common stock at an average price per share of $46.51 
(including commissions calculated at the average price per share) for a total amount of $79.7 million.	
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 40 registered patents and 19 
pending patents in the United States and 5 pending patents internationally. We have 63 registered trademarks and 9 

 
19
pending trademark applications in the United States, and 159 trademarks and 18 pending trademark applications internationally. We also 
currently offer 45 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. 
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 data rights to our intellectual property. Government agencies may in turn provide 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 provide to us the right to utilize 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, 
Defense Federal Acquisition Regulation, or DFARS, the Truthful Cost and Pricing Data 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 
government agency policies and 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.
On January 31, 2020, the U.S. Department of Defense (DOD) released the Cybersecurity Maturity Model Certification (“CMMC”) 
program as a framework to assess and enhance the cybersecurity posture of the Defense Industrial Base (“DIB”), particularly as it relates to 
controlled unclassified information (CUI) within the supply chain. CMMC is designed to ensure that contractors providing services to the U.S. 
DOD have implemented cybersecurity controls and processes to adequately protect information that resides on DIB systems and networks. 
An interim rule was issued on September 29, 2020, to amend the Defense Federal Acquisition Regulation Supplement (DFARS) by adding a 
new DFARS clause, 252.204-7021, which specifies CMMC requirements and enables the DOD to verify the protection of the Federal 
Contract Information (FCI) and CUI within the unclassified networks of DIB companies. DOD initiated an internal review and ultimately 
published draft “Version 2.0” of the CMMC program structure in November 2021.The DOD finalized the CNNC Program rule 32 CFR on 
October 15, 2024 and went into effect on December 16, 2024.
The CMMC is codified in two parts. The first, 32 CFR defines the requirements for CMMC and grants C3PAOs (CMMC 3rd Party 
Assessment Organizations) the ability to conduct CMMC assessments, and companies now have the ability to have official CMMC 
assessments conducted. The second is the 48 CFR. This rule will enforce the CMMC requirements in new and existing contracts and will 
allow the DOD to require a specific CMMC level in a solicitation or contract. This rule is currently in the adjudication/comment review process. 
The DOD has not yet provided details of timeliness for final 

 
20
implementation of this rule. The expectation is for the rule to be completed in mid-to-late 2025. Initially, the DFARS 252.204-7012 clause 
required companies to self-attest their compliance with NIST 800-171, but with the implementation of CMMC, companies will be required to 
be officially assessed by a C3PAO or DIBCAC (Defense Industrial Base Cybersecurity Assessment Center) depending upon the certification 
level pursued.
As part of the Defense Contract Management Agency (DCMA) Joint Surveillance Voluntary Assessment (JSVA) Program, Parsons 
procured an authorized C3PAO, that along with the DIBCAC, conducted a High Confidence (CMMC Level 2) Assessment for the Parsons’ 
FedNet® Secure environment in July 2023. Parsons is currently DFARS/NIST 800-171 compliant, and we anticipate that Parsons will be 
CMMC Level 2 certified once the CMMC program goes into effect. All 110 control requirements and 320 control objectives with NIST 800-171 
were deemed 100% satisfied as per the DIBCAC’s SPRS entry and official report. Parsons anticipates expanding the CMMC Level 2 
certification to additional networks in 2025.  
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 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, 

 
21
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.

23
Risk Factors Summary
The following is a summary of the principal risks that could adversely affect our business, operations and financial results.
Risk Relating to Our Business 
•
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.
•
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.

 
24
•
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.
•
Our business is subject the impact of supply chain disruption and inflation risk upon the cost of providing materials and services 
to customers and upon the profitability for certain contracts. 
•
Our business may be impacted by the imposition of tariffs upon markets in which we conduct business.
•
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, neighboring regions, and other regions across the globe, and these regions may 
experience turmoil, political upheaval and similar crises that may impact our current projects, future business, and financial 
stability.
•
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.
•
The impact of extreme weather events, including floods, hurricanes, droughts, and wildfires, including as a result of climate 
change or supply shortages, could have an adverse impact on our business and operations. 
•
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 global COVID-19 pandemic and variants thereof. The pandemic 
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. While many of these restrictions have been removed or reduced, the spread of new variants or viruses 
may result in the imposition of additional restrictions. In addition, governments and central banks in several parts of the world 
have enacted, or may enact in the future, fiscal and monetary stimulus measures to counteract the impacts of any such 
emergency. The extent to which any emergency may impact our business will depend on future developments, which are highly 
uncertain and unpredictable, and the resultant 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. Further, the economic impact of such events may cause extreme volatility in financial and other capital markets which 
may continue to adversely impact our stock price and our ability to access capital markets. Health emergencies may also have 
the effect of heightening many of 

 
25
the other risks described in this Annual Report on Form 10-K for the year ended December 31, 2023, such as those relating to 
government spending and priorities.
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 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, 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. 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; 
•
efforts to improve efficiency and reduce costs affecting government programs; 
•
changes or delays in government programs that we support or the programs’ requirements; 
•
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; 
•
continuing resolutions (CRs) which are temporary spending bills that allow federal government operations to continue when final 
appropriations have not been enacted. CRs generally continue the level of funding from the prior year’s appropriations or the 
previously approved CR from the current year;
•
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; 

 
26
•
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 negatively affect the U.S. government expenditures on defense, 
intelligence, and civil programs for which we provide support. Two customer sets within the federal government exceeded 20% of Parsons’ 
revenue during 2024. Parsons was awarded the second option year to continue our contract with a confidential customer through February 
2026. However, a related program performed by others has recently been paused, which impacts our ability to complete the scope of our 
mission. The long-term continuation of our contract is contingent on the related program restarting. If the project is halted, it would have a 
material adverse impact.
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 
and priorities may affect our Critical Infrastructure business and operations. 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.

 
27
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 23% and 18% of accounts 
receivable as of December 31, 2024 and December 31, 2023, respectively 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, including the U.S. Department of Defense, 
the U.S. Department of State, the Federal Aviation Administration, the United States Intelligence Community, and other federal civilian 
customers 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.
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 

 
28
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. 
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; 

 
29
•
for contracts subject to the Truthful Cost and Pricing statute, 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; 
•
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’ ability 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;
•
the impact of inflation upon the cost of services and materials provided to customers; and 
•
our need to devote time and resources to training, business development, and other non-chargeable activities. 
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 

 
31
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 deploy our people efficiently and effectively 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.
We have submitted claims and change orders to clients for work we performed beyond the initial scope of some of our contracts. If 
these clients do not approve these claims and change orders, our results of operations could be adversely impacted. 
We typically have pending claims and change orders submitted under some of our contracts for payment of work performed beyond 
the initial contractual requirements for which we have already recorded revenue. 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.

 
32
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 
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.
Changes in global tax laws or their interpretation could have a material impact on our effective income tax rate.
We are subject to income taxes in the U.S. and numerous foreign jurisdictions. Accordingly, our effective tax rate is impacted by 
changes in the mix among earnings in countries with differing tax rates. Due to economic and political conditions, many tax jurisdictions, 
including the U.S., have called for comprehensive changes to fiscal and tax policies that could significantly impact how we are taxed on our 
domestic and foreign earnings. Such changes, if enacted into law, could increase our effective tax rate and have a material adverse impact 
on our financial condition and results of operations. For example, the Organization for Economic Co-Operation and Development continues 
to advance proposals for modernizing international tax rules, including the release of global minimum tax standards referred to as the Pillar 
Two Model Rules (and also referred to as the Global Anti-Base Erosion (“GloBE” rules). Several jurisdictions in which we operate have 
enacted these rules, some of which became effective for the Company’s 2024 fiscal year. The Company has considered the impact of the 
GloBE implementation in its provision for income taxes and continues to monitor the impacts of the GloBE rules implementation. 
We are also subject regularly to examination by tax authorities. Although we believe that our positions are reasonable, they could be 
materially affected by many factors, including the final outcome of tax audits, introduction of new tax legislation or regulations and related 
interpretations. We regularly assess the likelihood of an adverse outcome resulting from these examinations to determine the adequacy of 
our provision for taxes. There can be no assurance as to the outcome of these examinations. If the ultimate determination of our taxes owed 
is for an amount in excess of amounts previously accrued, our financial condition and results operation could be materially affected.

 
33
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. 
12% of our revenue during fiscal 2024, 13% of our revenue during fiscal 2023 and 12% of our revenue during fiscal 2022 was derived 
from our operations through consolidated joint ventures. In addition, 2.7% of our revenue during fiscal 2024, 3.9% of our revenue during 
fiscal 2023 and 5.1% of our revenues in fiscal 2022 related to services we provided to our unconsolidated joint ventures, where control 
resides with unaffiliated third parties, and 5.5% of our operating income during fiscal 2024, 16.6% of our operating income during fiscal 2023 
and 8.8% of our operating income during fiscal 2022 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 

 
34
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. As of December 31, 2024, we had $176.7 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 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.

 
35
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 42% of our total revenue during fiscal 2024, 33% of our total revenue during 
fiscal 2023, and 27% of our total revenue during fiscal 2022. 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 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.

 
36
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, 2024, we had goodwill and intangible assets of $2.4 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 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. 

 
37
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 cyber 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; 
•
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. 

 
38
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 
Federal Acquisition Regulations, 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 and similar documents. 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 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.

 
39
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 varied 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 complex 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 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 

 
40
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 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 22.6% in 2024, 
24.4% in 2023 and 24.9% in 2022. There are risks inherent in doing business internationally, including: 
•
imposition of governmental controls and changes in laws, regulations or policies; 
•
political and economic instability and turmoil internationally, including countries in the Middle East; 
•
civil unrest, acts of terrorism, force majeure, war, or other armed conflict, including the ongoing war and unrest in Israel, which 
has the potential to impact other countries in the Middle East; 
•
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, variants 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, neighboring regions, and other regions across the globe, and these regions may 
experience turmoil, political upheaval or similar crises 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. This part of 
the world often has conflicts, such as the current Israel-Hamas situation. Further, we may undertake work in other countries that may 
experience turmoil, political upheaval, or other similar crises. 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 
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. 

 
42
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 be certain 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, 2024, our total backlog was $8.9 billion, of which $5.9 billion was funded. Our backlog includes orders under 
contracts that can extend for several 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 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.

 
43
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, 2024, our accounts receivable, net was $1.1 billion 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, 2024, our total indebtedness was approximately $1.2 billion. Our Credit Agreement and the agreements governing 
our Delayed Draw Term Loan and Convertible 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 
an interest 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; 
•
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. 

 
44
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 Internal Revenue 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 Internal Revenue Code (Code) and the 
Employment Retirement Income Security Act (ERISA). The ESOP 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 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 

 
45
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 are signatory to approximately fourteen active union collective bargaining agreements as of December 31, 2024 and employ more 
than 300 employees represented by unions. 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. 
Risk Related to Our Common Stock 
If we are unable to 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. 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 in a timely manner with the management certification requirements of Section 404 of the Sarbanes-Oxley Act as to 
the effectiveness of our internal control over financial reporting 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. 

 
46
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. 
Quarterly operating results may fluctuate. 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 
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; 

 
47
•
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 by the ESOP could cause the market price of our 
common stock to drop significantly. 
At December 31, 2024, we had 146,656,225 shares of our common stock issued and 106,775,350 outstanding. Of these shares, 
54,117,904 shares are owned by the ESOP, 52,657,447 shares are publicly owned, and 39,880,875 shares are Treasury stock. We are party 
to a registration rights agreement with the ESOP Trustee, 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, 2024, there were 54,117,904 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. 
In April 2022, the board of directors approved an amendment providing for lump sum distributions to participants and removing the annual 

 
48
installments. Annual diversification elections and five-year vested termination distributions are not impacted by this amendment and will still 
occur annually and over installments as outlined in the Plan.
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 853,343,775 shares of common stock authorized but not outstanding and not reserved for issuance under 
our 2021 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 633,033 shares in fiscal 2024, 915,113 shares in fiscal 2023, and 1,188,129 shares in 
fiscal 2022 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 2024, 2023 and 2022, 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 ESOP 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 51% of our outstanding common stock, 40% of 
which is owned by current employees of Parsons Corporation. 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. 
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. 

 
49
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 51% of the voting power of our common stock as of December 31, 2024. 
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. 
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; 

 
50
•
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 has the effect of requiring 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 (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 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 have no current plans to declare dividends. 
We do not currently pay a dividend and have no current plans to declare any cash dividends to holders of our common stock. 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 

 
51
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 1C. Cybersecurity. 
We have developed and implemented a cybersecurity risk management program intended to protect the confidentiality, integrity, and 
availability of our critical systems and information. Our cybersecurity risk management program includes a cybersecurity incident response 
plan. 
	
We use NIST Cybersecurity Framework and CIS Critical Security Controls as a guide to help us identify, assess, and manage 
cybersecurity relevant to our business. We are also structured to CMMC which aligns with DOD/Federal contractor program compliance. This 
does not imply that we meet any particular technical standards, specifications, or requirements.
	
Our cybersecurity risk management program is integrated with our overall enterprise risk management program, and shares 
common methodologies, reporting channels and governance processes that apply across the enterprise risk management program to other 
legal, compliance, strategic, operational, and financial risk areas. Our cybersecurity risk management program includes the following key 
elements:
•
risk assessments designed to help identify material cybersecurity risks to our critical systems, information, services, and our 
broader enterprise IT environment;
•
a team comprised of IT security, IT infrastructure, and IT compliance personnel principally responsible for directing (1) our 
cybersecurity risk assessment processes; (2) our security processes; and (3) our response to cybersecurity incidents;
•
the use of external cybersecurity service providers, where appropriate, to assess, test or otherwise assist with aspects of our 
security processes;
•
cybersecurity awareness training of employees with access to our IT systems;
•
a cybersecurity incident response plan and Security Operations Center to respond to cybersecurity incidents;
•
a third-party risk management process for service providers.
We have not identified risks from known cybersecurity threats, including as a result of any prior cybersecurity incidents, that have 
materially affected us, including our operations, business strategy, results of operations, or financial condition. We face certain ongoing risks 
from cybersecurity threats that, 

 
52
if realized, are reasonably likely to materially affect us, including our operations, business strategy, results of operations, or financial 
conditions, as we have described in the Risk Factors section of this Form 10-K.
Cybersecurity Governance
	
Our Board considers cybersecurity risk as critical to the enterprise and delegates the cybersecurity risk oversight function to the 
Audit and Risk Committee. The Audit and Risk Committee oversees management’s design, implementation, and enforcement of our 
cybersecurity risk management program.
	
Our Chief Security & Risk Officer reports to the Chief Technology Officer and works closely with the Chief Legal Officer to ensure 
that all disclosure or reporting requirements are satisfied if an incident were to occur. The Chief Security & Risk Officer leads Parsons’ overall 
cybersecurity function and provides quarterly reports to the Audit and Risk Committee on our cybersecurity risks, including briefings on our 
cybersecurity risk management program and cybersecurity incidents. The Audit and Risk Committee also receives periodic presentations on 
relevant cybersecurity topics as part of the Committee and the Board’s continuing education on topics that impact public companies.
	
Our Chief Security & Risk Officer supervises efforts to prevent, detect, mitigation and remediate cybersecurity risks and incidents 
through various means, which include briefings from internal security personnel; threat intelligence and other information obtained from 
governmental, public or private sources, including external cybersecurity service providers; and alerts and reports produced by security tools 
deployed in the IT environment. Our Chief Security & Risk Officer is responsible for assessing and managing our material risks from 
cybersecurity threats and has primary responsibility for leading our overall cybersecurity risks management program and supervises both our 
internal cybersecurity personnel and our external cybersecurity service providers. Our Chief Security & Risk Officer has significant global 
experience in managing and leading IT and cybersecurity teams. 
Item 2. Properties. 
Our headquarters are located in Chantilly, Virginia. As of December 31, 2024, we leased 246 commercial facilities (including our 
headquarters) with an aggregate of approximately 2.7 million square feet of space across 38 U.S. states and 15 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. 
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 

 
53
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. The court heard dispositive motions in 2023, including Parsons’ motion for summary judgment. We 
are awaiting the court’s rulings upon such motions, which will determine whether a trial will be necessary for this matter in 2025.
On July 1, 2024, a final judgment was filed with the clerk of the Superior Court of the State of California In and For the County of San 
Mateo with an award of damages in the total amount of approximately $102.5 million in favor of Parsons Transportation Group, Inc. and 
against Alstom Signaling Operations LLC (Alstom"). This proposed award relates back to a lawsuit Parsons initially filed against the 
Peninsula Corridor Joint Powers Board for breach of contract and wrongful termination in February 2017 (which was settled between 
Parsons and the Joint Powers Board in 2021) and a cross-complaint filed against Alstom Signaling Operations LLC in November 2017, as 
subsequently amended, for breach of contract, negligence and intentional misrepresentation. On September 23, 2024, the Court awarded 
pre-judgment interest in the amount of $34.0 million and amended the judgment accordingly to include such interest. Alstom filed a Notice of 
Appeal and has posted a bond as required under California law. 
At this time, the Company is unable to determine the probability of the outcome of the litigation.
Item 4. Mine Safety Disclosures.
Not Applicable.

Dividend Policy
During the years ended December 31, 2024, 2023 and 2022, the Company did not declare any dividends. We currently do not intend 
to declare or pay any cash dividends in the foreseeable future. Any 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 Convertible Senior Notes, or the Delayed Draw Term Loan and Credit Agreement, and other factors that 
our board of directors considers relevant.
Shareholders
According to the records of our transfer agent, there were three shareholders of record as of February 11, 2025.

Issuer Purchases of Equity Securities
On August 9, 2021, the Company’s Board of Directors authorized the Company to acquire a number of shares of Common Stock 
having an aggregate market value of not greater than $100 million from time to time, commencing on August 12, 2021. The Board further 
amended this authorization in August 2022 to remove the prior expiration date and grant executive leadership the discretion to determine the 
price for such share repurchases. The Board further amended this authorization in February 2024 to restore the repurchase capacity to $100 
million and removed the $25 million quarterly cap on such repurchases. 
At the time of the February 2024 authorization, the Company had repurchased shares with an aggregated market value (including 
fees) of $54.7 million. The aggregate market value of shares of Common Stock the Company is authorized to acquire, from both the August 
2021 and February 2024 authorizations, is not greater than $154.7 million. 
As of December 31, 2024, the Company has spent $79.7 million (which includes commissions paid of $34 thousand) repurchasing 
1,713,481 shares of Common Stock at an average price of $46.51 per share.

Overview 
We are a leading provider of the integrated solutions and services required in today’s complex security environment and a world of 
digital transformation. We deliver innovative technology-driven solutions to customers worldwide. We have developed significant expertise 
and differentiated capabilities in key areas of cyber and intelligence, space and missile defense, critical infrastructure protection, 
transportation, environmental remediation and urban development. By combining our talented team of professionals and advanced 
technology, we solve complex technical challenges to enable a safer, smarter, more secure and more connected world. 

 
58
We operate in two reporting segments, Federal Solutions and Critical Infrastructure. Our Federal Solutions business is an advanced 
technology provider to the U.S. government. Our Critical Infrastructure business provides integrated design and engineering services for 
complex physical and digital infrastructure around the globe. 
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. 
Key Metrics 
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):

Difference between our backlog of $8.9 billion and our remaining unsatisfied performance obligations, or RUPO, of $6.7 billion, each 
as of December 31, 2024, is due to (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.
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):

The change in new awards from year to year is primarily due to ordinary course fluctuations in our business. 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.
The change in new awards in both our Federal Solutions and Critical Infrastructure segments for the year ended December 31, 2024 
when compared to the corresponding period last year was primarily due to significant option period awards in our Federal Solutions segment 
and three large transportation awards and a mining award in our Critical Infrastructure segment.

 
59
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. Unfunded backlog 
does not include potential task orders expected to be awarded under multiple awards IDIQ contract vehicles, where task orders 
are competitively awarded and separately priced.
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. 
The following table summarizes the value of our backlog at the respective dates presented (in thousands):

Difference between our backlog of $8.9 billion and our RUPO of $6.7 billion, each as of December 31, 2024, is due to (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 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 $3.9 billion of our funded backlog at December 31, 2024 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.” 

 
60
The changes in backlog in both the Federal Solutions and Critical Infrastructure segments were primarily from ordinary course 
fluctuations in our business and the impacts related to the Company’s awards discussed above. Our backlog will fluctuate in any given period 
based on the volume of awards issued and the rate of 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 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:

Factors and Trends Affecting Our Results of Operations 
We believe that the financial performance of our business and our future success are dependent upon many factors, including those 
highlighted in this section. 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 cyber, 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 

 
61
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, 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.

solutions, biometrics, and global threat assessment and operations, increasing our addressable market in both the Federal Solutions and 
Critical Infrastructure segments. The financial results of Xator have been included in our consolidated results of operations from May 31, 
2022 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 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. 
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. 

 
63
We enter into the following types of contracts with our customers: 
•
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 description of our policies on revenue recognition applicable to each type of contract. 
The table below presents the percentage of total revenue for each type of contract.

The amount of risk and potential reward varies under each type of contract. 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.
The significant change in the contract mix for the year ended December 31, 2024 compared to the corresponding period last year 
relates to increased business volume from a significant fixed price contract in our Federal Solutions segment.
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.
The Company is involved in a significant volume of contracts with the United States federal government and state and local 
governments. Approximately 59%, 55%, and 53% of consolidated revenues for the years ended December 31, 2024, December 31, 2023 
and December 31, 2022, 

 
64
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.
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 (losses) of unconsolidated joint ventures. 
Our revenues included $182.6 million in 2024, $213.8 million in 2023, and $217.4 million in 2022 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 selling, 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 2024, 2023 and 2022, 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 $59.8 million for 2024, $58.2 million for 
2023, and $54.7 million for fiscal 2022, and is recorded in “Direct cost of contracts” and “Selling, 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. 
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. 
Selling, general and administrative expenses (“SG&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, and other income, net. 
Interest income primarily consists of interest earned on U.S. government money market funds. 
Interest expense consists of interest expense incurred under our Convertible Senior Notes, Credit Agreement and Delayed Draw Term 
Loan. 
Other income, net primarily consists of gain or loss on sale of assets, sublease income. transaction gain or loss related to movements 
in foreign currency exchange rates, contingent consideration and convertible debt repurchase loss.

Equity in losses of unconsolidated joint ventures for the year ended December 31, 2024 improved by $24.4 million compared to the 
prior year. Impacting equity in losses of unconsolidated joint ventures for the year ended December 31, 2024 were write-downs of $51.7 
million related to Parsons' participation in a design build joint venture. For the year ended December 31, 2023 the Company had write-downs 
of $83.4 million, inclusive of $57.9 million related to the design build joint venture referenced above. Results for the year ended December 
31, 2023 also included earnings on higher margin change orders which did not reoccur for the year ended December 31, 2024. Joint venture 
volume has decreased year-over-year as we move away from our participation in construction joint ventures.

Interest income is related to interest earned on investments in government money funds. Interest income increased for the year ended 
December 31, 2024 compared to the corresponding period last year is due to higher cash balances held and increased interest rates 
compared to the corresponding period last year.
Interest expense for the year ended December 31, 2024 is primarily due to debt related to our Convertible Senior Notes and Delayed 
Draw Term Loan. The increase in Interest expense for the year ended December 31, 2024 compared to the corresponding period last year is 
primarily related to an increase in debt balances and a $3.2 million charge from the acceleration of the amortization of debt issuance costs 
associated with the partial repurchase of the 0.25% Convertible Senior Notes due 2025 discussed below. 
During the year ended December 31, 2024, we paid $495.6 million in cash to repurchase $284.6 million aggregate principal amount of 
our Convertible Senior Notes due 2025 (the "Repurchase Transaction") concurrently with the offering of 2.625% Convertible Senior Notes 
due 2029. As a result of the Repurchase Transaction, we incurred an $18.4 convertible debt repurchase loss1. The Repurchase Transaction 
is a partial repurchase of our Convertible Senior Notes due 2025. See “Note 11 – Debt and Credit Facilities,” for a further discussion of this 
transaction.
1During the first quarter of 2024, prior to the early adoption of ASU 2024-04, the Company recorded a $211.0 million loss on debt extinguishment associated 
with the 0.25% Convertible Senior Notes due 2025. Please see "Note 2—Summary of Significant Accounting Policies—New Accounting Pronouncements" for a 
discussion of the Company's adoption of ASU 2024-04. As a result of the early adoption, the extinguishment charge was reversed from the 

 
67
Company's consolidated financial statements and a convertible debt repurchase loss was recorded as described above.
The amounts in other income (expense), net, are primarily related to transaction gains and losses on foreign currency transactions, 
sublease income, and a change in the fair value of contingent consideration.

Income tax expense increased in fiscal 2024 primarily due to an increase in overall pre-tax income, increases in current year foreign 
Net Operating Losses (NOLs) subject to valuation allowances and an increase in non-deductible executive compensation subject to Section 
162(m), partially offset by increases in the foreign-derived intangible income (FDII) deduction, and increased equity based-compensation 
deductions.
Our effective tax rate was 20.9% and 21.3% for the years ended December 31, 2024 and 2023, respectively. The difference between 
the statutory U.S. federal income tax rate of 21% and the effective tax rate for the year ended December 31, 2024 primarily relates to state 
income taxes, valuation allowance and executive compensations subject to Section 162(m) offset by benefits related to untaxed income 
attributable to noncontrolling interests, earnings in lower tax jurisdictions, the FDII deduction, and equity-based compensation.
In 2021 the Organization for Economic Co-operation and Development (OECD) announced an inclusive Framework on Base Erosion 
and Profit Shifting (BEPS) including Pillar Two Model Rules defining the global minimum tax, also known as the Global Anti-Base Erosion 
(GloBE), which aims to ensure that multinational enterprises (MNEs) pay a 15% minimum level of tax regardless of where the MNE operates. 
The OECD released additional administrative guidance in June 2024 and January 2025. Many non-US tax jurisdictions have either recently 
enacted legislation to adopt components of the Pillar Two Model Rules beginning in 2024 and/or have announced their plans to enact 
legislation in future years. The Company has evaluated the implementation of Pillar Two on its 2024 income tax position based on currently 
enacted legislation and has determined there is no material impact. We are continuing to evaluate the potential impact on future periods of 
the Pillar Two Framework, pending enactment of legislation by individual countries.

Income tax expense increased in fiscal 2023 primarily due to an increase in overall earnings and an increase in foreign withholding 
taxes partially offset by increases in the foreign-derived intangible income (FDII) deduction and earnings in lower tax jurisdictions.
Our effective tax rate was 21.3% and 23.9% for the years ended December 31, 2023 and 2022, respectively. The difference between 
the statutory U.S. federal income tax rate of 21% and the effective tax rate for the year ended December 31, 2023 primarily relates to state 
income taxes, valuation allowance on foreign tax credit carryovers originating from foreign withholding taxes offset in part by 

 
70
benefits related to income attributable to noncontrolling interests, earnings in lower tax jurisdictions, the FDII deduction, and federal business 
tax credits.
Effective for tax year 2022, the Tax Cuts and Jobs Act of 2017 eliminated the option to currently deduct research and development 
expenditures in the year incurred and requires taxpayers to amortize such expenditures over five years for tax purposes (15 years for foreign 
research and development expenditures). This provision resulted in additional cash tax liability for the 2023 tax year of approximately $12 
million. To date, there has been no enacted legislation that would change the tax treatment of these research and development expenditures 
and the Company continues to capitalize and amortize these expenses in accordance with the law.

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 

 
71
things, impairment of goodwill, intangible and other assets, interest and other expenses recognized on litigation matters, 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. 
See “Segment Results” below and "Note 20—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 increase in Federal Solutions revenue for the year ended December 31, 2024 compared to the corresponding period last year was 
primarily related to organic growth of 30% and $73.6 million from business acquisitions. Organic growth was primarily due to the ramp up of 
recent awards including growth on a significant contract, growth of existing contracts, partially offset by the winding down of certain contracts. 
Revenue for the year ended December 31, 2023 included incentive fees on two contracts of approximately $20 million that did not reoccur for

The increase in Critical Infrastructure Adjusted EBITDA attributable to Parsons for the year ended December 31, 2024 compared to

approximately $20 million. These increases were offset by higher selling general and administrative costs from business acquisitions, 
business development and sales activities, and incentive compensation costs as a result of the company's strong operating performance and 
growing employee base.

The increase in Critical Infrastructure revenue for the year ended December 31, 2023 compared to the corresponding period last year 
was substantially due to organic growth.
The increase in Critical Infrastructure Adjusted EBITDA attributable to Parsons for the year ended December 31, 2023 compared to 
the corresponding period last year was primarily due to increases in business volume and a decrease in direct cost of contracts of $38 million 
related to a legal matter on a previously completed contract, offset by write-downs on joint ventures discussed above and higher selling 
general and administrative costs from business development and sales activities and higher incentive compensation costs as a result of the 
company's strong operating performance and growing employee base. 
Liquidity and Capital Resources
We currently finance our operations and capital expenditures through a combination of internally generated cash from operations, our 
Convertible Senior Notes, Delayed Draw Term Loan and periodic borrowings under our Revolving Credit Facility. 
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 Revolving Credit Facility. 
As of December 31, 2024, 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. Management 
continually monitors debt maturities to strategically execute optimal terms and ensure appropriate levels of working capital liquidity are 
maintained for the company.
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. 

 
74
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 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 improve working capital. Net DSO was 55 days at December 31, 2024, 
down from 59 days at December 31, 2023 and 69 days at December 31, 2022. Our working capital (current assets less current liabilities) was 
$546.8 million at December 31, 2024, $726.6 million at December 31, 2023 and $611.7 million at December 31, 2022. 
Our cash and cash equivalents increased by $180.6 million to $453.5 million at December 31, 2024 from $272.9 million at December 
31, 2023. This compares to an increase in cash and cash equivalents of $10.4 million to $272.9 million at December 31, 2023 from $262.5 
million at December 31, 2022.

Operating Activities 
Net cash provided by operating activities consists primarily of net income adjusted for noncash items, such as: equity in (losses) 
earnings of unconsolidated joint ventures, contributions of treasury stock, depreciation and amortization of property and equipment and 
intangible assets, provisions for doubtful accounts, amortization of deferred gains, and impairment charges. 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 $115.9 million to $523.6 million during 2024 compared to $407.7 million during 
2023. The increase in net cash provided by operating activities is primarily due to a $98.4 million change in net income after adjusting for 
non-cash items and convertible debt settlement and from changes in our working capital accounts of $46.4 million (primarily from contract 
assets and prepaid expenses and other assets offset by accounts payable, accrued expenses and other current liabilities, and contract 
liabilities). These increase were offset by a $29.0 million change in cash used for other long-term liabilities. 
Net cash provided by operating activities increased $170.2 million to $407.7 million during 2023 compared to $237.5 million during 
2022. The increase in net cash provided by operating activities is primarily due to a $170.1 million change in net income after adjusting for 
non-cash items and the 10-day improvement in DSO. This increase was offset, in part, from changes in our working capital accounts of $6.3 
million. The changes in the Company's various working capital accounts were driven primarily by the significant increase in business volume 
during the year ended December 31, 2023 compared to the corresponding period last year.

 
75
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 increased $180.7 million to $556.7 million during 2024 compared to $376.0 million during 2023. 
The change was primarily driven by a $206.8 million increase in payments for acquisitions, $14.3 million from investments in unconsolidated 
joint ventures, and $8.8 million from capital expenditures offset by a $49.9 million increase in return of investments in unconsolidated joint 
ventures.
Net cash used in investing activities decreased $41.5 million to $376.0 million during 2023 compared to $417.5 million during 2022. 
The change was primarily driven by a $157.5 million reduction in payments for acquisitions offset in part by a $102.0 million increase in 
investments in unconsolidated joint ventures, a $9.8 million increase in capital expenditures (primarily from computer systems and 
equipment) and a change from return of investments in unconsolidated joint ventures of $4.4 million. 
Financing Activities 
Net cash provided by (used in) financing activities is primarily associated with proceeds from debt, the repayment thereof, transactions 
related to the Company’s common stock, and contributions by and distributions to noncontrolling interests.
Net cash provided by (used in) financing activities increased by $240.6 million to $218.7 million in 2024 compared to $(21.9) million in 
2023. The change in cash flows from financing activities is primarily driven by net cash inflows from our convertible bond transactions which 
generated $285.4 million in cash. See “Note 11 – Debt and Credit Facilities,” for a further discussion of these transactions. This increase was 
offset in part by distributions to noncontrolling interests of $16.7 million, taxes paid on vested stock of $15.3 million and $14.0 million from 
repurchases of common stock. 
Net cash provided by (used in) financing activities changed by $122.2 million to $(21.9) million in 2023 compared to $100.4 million in 
2022. This change was primarily due to a decrease of $150.0 million from net borrowing related activities and a $7.4 million change in 
contributions by noncontrolling interests offset by a decrease in distributions to noncontrolling interests of $11.6 billion, a decrease in cash 
used to repurchase common stock of $11.0 million and from $11.2 million of payments in warrants for the year ended December 31, 2022 
that did not reoccur in 2023.
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 $328.4 million as of 
December 31, 2024. Letters of credit outstanding under the Credit Agreement total $43.0 million. 
 
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 

 
76
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 
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. 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 award and incentive fees, increases to the 
transaction price for approved and unpriced change orders, claims, 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. 
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 

 
77
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
We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (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.

 
78
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 eleven 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 third 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.
Certain business acquisitions include contingent earn-out arrangements, which are generally based on meeting a revenue target. The 
fair value of this contingent consideration is included as part of the purchase price of the acquired company on the acquisition date and 
recorded at its fair value within other liabilities or other long-term liabilities, as appropriate on the consolidated balance sheets.
We measure our contingent consideration at fair value on a recurring basis using significant unobservable inputs classified within Level 
3 of the fair value hierarchy. The fair value of contingent consideration is determined using the option pricing method prescribed in the 
earnout valuation guide published by The Appraisal Foundation. We consider three major risks associated with earnout, i.e. risk in the 
underlying metric, risk in the earnout structure, and counterparty credit risk. Our valuation model is based on the Black Scholes option pricing 
formula and major assumptions including projected revenue, the revenue discount rate, the revenue volatility, and the Company's credit 
adjusted discount rate. Subsequent adjustments to these assumptions can cause changes to the measure of contingent consideration.
The Company reassess the estimated fair value of contingent consideration on a quarterly basis with any change in the fair value 
recorded to selling, general and administrative expense in the current quarter. The updated fair value could differ materially from the 
acquisition date fair value. The amount of contingent consideration ultimately paid that is less than or equal to the liability on the acquisition 
date is reflected as cash used in financing activities in our consolidated statements of cash flows. Any amounts paid in excess of the liability 
on the acquisition date is reflected as cash used in operating activities in our consolidated statements of cash flows.
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. 
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 

 
79
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. 
We perform a goodwill impairment test annually, on October 1st of each year, 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, 2024, December 31, 
2023 and December 31, 2022, 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 2029. 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, 2024 (i.e., the first day of our fourth quarter in fiscal 2024), 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. 
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, 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. 
ESOP 
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, whichever occurs first.

 
81
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 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.
Equity-Based Compensation
We measure 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. Awards containing performance measures are 
adjusted at each reporting period for the number of shares expected to be earned. Compensation cost for performance awards are trued-up 
at each reporting period for changes in 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 “Selling, general 
and administrative expenses” in the consolidated statements of income. For awards that include market conditions, the grant date fair value 
is determined using a Monte Carlo simulation.
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 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. Actual losses and related expenses may deviate, perhaps substantially, from the self-insurance liability estimates 
reflected in our financial statements.

As of December 31, 2024, 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 the Company’s Revolving Credit Facility and Delayed Draw Term Loan.
As of December 31, 2024 and December 31, 2023, there were no amounts outstanding under the Revolving Credit Facility. 
Borrowings under the Revolving Credit Facility effective June 2021 bear interest at either an adjusted Term SOFR rate plus a margin 
between 1.0% and 1.625%, or a base rate (as defined in the Credit Agreement) plus a margin of between 0% and 0.625%, both based on 
the leverage ratio of the Company at the end of each quarter. 
As of December 31, 2024, there was $350.0 million outstanding under the 2022 Delayed Draw Term Loan. Borrowings under the 2022 
Delayed Draw Term Loan Agreement will bear interest at either an adjusted Term SOFR benchmark rate plus a margin between 0.875% and 
1.500% or a base rate plus a margin of between 0% and 0.500% and will initially bear interest at the middle of this range. The Company will 
pay a ticking fee on unused term loan commitments at a rate of 0.175% commencing with the date that is ninety (90) days after the Closing 
Date. The interest rate at December 31, 2024 and December 31, 2023 was 5.6% and 6.6%, 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.
The information required by this item 8 is submitted as a separate section beginning on page F-1 of this Annual Report on Form 10-K 
and is incorporated by reference.
Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.
None.
Item 9A. Controls and Procedures.
Evaluation of Disclosure Controls and Procedures
Our management carried out, as of December 31, 2024, 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, 2024, 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, 2024 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, 2024.
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, 2024, as stated in their audit report included in this Annual Report on Form 10-K.
Consistent with the guidance issued by the Securities and Exchange Commission Staff, management has excluded BlackSignal and 
BCC from its assessment of internal controls over financial reporting as of December 31, 2024. BlackSignal a wholly owned subsidiary, which 
we acquired on August 16, 2024, has total assets and revenue of 4.3% and 0.3%, respectively of the related consolidated financial statement 
amounts as of and for the year ended December 31, 2024. BCC a wholly owned subsidiary, which we acquired on November 1, 2024, has 
total assets and revenue of 4.8% and 0.3%, respectively of the related consolidated financial statement amounts as of and for the year 
ended December 31, 2024.
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, 2024 that materially affected, or are reasonably likely 
to materially affect, our internal control over financial reporting.
Item 9B. Other Information.
Insider Trading Relationships and Policies
During the fiscal quarter ended December 31, 2024, no director or named executive officer of the Company adopted or terminated a 
"Rule 10b5-1 trading arrangement" or a "non-Rule 10b5-1 trading arrangement" (in each case, as defined in Item 408 of Regulation S-K).
Item 9C. Disclosure Regarding Foreign Jurisdictions that Prevent Inspections.

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, 2024 and 2023, and the related consolidated statements of income, of comprehensive income, of changes in shareholders’ 
equity and of cash flows for each of the three years in the period ended December 31, 2024, including the related notes and schedule of 
valuation and qualifying accounts for each of the three years in the period ended December 31, 2024 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, 2024 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, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period 
ended December 31, 2024 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, 2024, based on 
criteria established in Internal Control - Integrated Framework(2013) issued by the COSO.
Change in Accounting Principle
As discussed in Note 2 to the consolidated financial statements, the Company changed the manner in which it accounts for debt with 
conversion and other options in 2024.
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 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 

 
F-3
performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis 
for our opinions.
As described in Management’s Annual Report on Internal Control over Financial Reporting, management has excluded BlackSignal 
Technologies, LLC (“BlackSignal”) and BCC Engineering, LLC (“BCC”) from its assessment of internal controls over financial reporting as of 
December 31, 2024, because they were acquired by the Company in purchase business combinations during 2024.  We have also excluded 
BlackSignal and BCC from our audit of internal control over financial reporting.  BlackSignal and BCC are wholly-owned subsidiaries whose 
total assets and total revenues excluded from management’s assessment and our audit of internal control over financial reporting represent 
approximately 4.3% and 4.8%, of total assets, respectively and approximately 0.3% and 0.3% of total revenues, respectively, of the related 
consolidated financial statement amounts as of and for the year ended December 31, 2024. 
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 matter communicated below is a matter arising from the current period audit of the consolidated financial statements that 
was communicated or required to be communicated to the audit committee and that (i) relates 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 matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to 
which it relates.
Revenue Recognition – Determination of Estimated Contract Cost and Variable Consideration Related to Estimated 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 $2.8 billion for 
the year ended December 31, 2024, which accounts for approximately 42% of the Company’s 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 

 
F-4
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. 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. 
The principal considerations for our determination that performing procedures relating to revenue recognition, specifically the determination 
of 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 judgment by management in determining the estimated contract cost and variable consideration 
related to estimated claims revenue for fixed-price contracts recognized over time; (ii) a high degree of auditor judgment, subjectivity, and 
effort in performing procedures and evaluating audit evidence for the 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 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 estimated contract cost and variable consideration related to estimated 
claims revenue, which included reading 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 estimated contract cost as compared with prior period estimates, including evaluating the timely identification of circumstances that 
may warrant a modification to the 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.

PARSONS CORPORATION AND SUBSIDIARIES 
Notes to Consolidated Financial Statements 
December 31, 2024, December 31, 2023 and December 31, 2022 
 
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.
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. Certain 
amounts may not foot due to rounding.
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; valuation of deferred income tax 
assets and uncertain tax positions, among others. 
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 retained earnings. 
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 
633,033 shares, 915,113 shares, and 1,188,129 shares of common stock were made to the ESOP in 2024, 2023 and 2022, respectively.

Share Repurchases
During the third quarter of 2021, the Company’s Board of Directors authorized the Company to acquire a number of shares of 
Common Stock having an aggregate market value of not greater than $100,000,000 from time to time. The Board further amended this 
authorization in February 2024 to restore the repurchase capacity to $100 million and removed the $25 million quarterly cap on such 
repurchases.
At the time of the February 2024 authorization, the Company had repurchased shares with an aggregated market value (including 
fees) of $54.7 million. The aggregate market value of shares of Common Stock the Company is authorized to acquire is now not greater than 
$154.7 million.
Repurchased shares of common stock are retired and included in “Repurchases of common stock” in cash flows from financing 
activities in the Consolidated Statements of Cash Flows. 
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 using the if-converted method by dividing adjusted 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    
In accordance with Account Standard Update ("ASC") 606 - Revenue From Contracts With Customers, the Company follows the five-
step process in ASC 606 to recognize revenue: 
1.
Identify the contract 
2.
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 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 non-
reimbursable 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

Notes to Consolidated Financial Statements 
December 31, 2024, December 31, 2023 and December 31, 2022 
 
 
F-12
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, 2024 and December 31, 2023. 
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 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 

PARSONS CORPORATION AND SUBSIDIARIES 
Notes to Consolidated Financial Statements 
December 31, 2024, December 31, 2023 and December 31, 2022 
 
 
F-13
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 revenue 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 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 

PARSONS CORPORATION AND SUBSIDIARIES 
Notes to Consolidated Financial Statements 
December 31, 2024, December 31, 2023 and December 31, 2022 
 
 
F-14
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.  
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.

F-15
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 59%, 55%, and 53% of consolidated revenues for the years ended December 31, 2024, December 31, 2023 
and December 31, 2022, respectively, and approximately 23% and 18% of accounts receivable as of December 31, 2024 and December 31, 
2023, 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. Two customer sets within the United States federal 
government represent over 20% of total Company revenue for the year ended December 31, 2024.
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. Awards 
containing performance measures are adjusted at each reporting period for the number of shares expected to be earned. Compensation cost 
for performance awards are trued-up at each reporting period for the number of shares expected to be earned pro-rated for the portion of the 
requisite 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 selling, general and administrative expense in the consolidated statements of income. For 
awards that include market conditions, the grant date fair value is determined using a Monte Carlo simulation.
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.
In determining the fair value of acquired intangible assets from our business acquisitions, the Company uses the multi-period excess 
earnings method to value customer relationships and backlog and values developed technologies using the relief-from royalty method. 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.
Certain business acquisitions include contingent consideration. Contingent consideration is recorded at its fair value, using a Black-
Scholes model, within other liabilities or other long-term liabilities, as appropriate. The fair value of contingent consideration involves the use 
of significant estimates and assumptions related to risks associated with earnout, i.e. risk in the underlying metric, risk in the earnout 
structure, counterparty credit risk, projected revenue, the revenue discount rate, the revenue volatility, and the Company's credit adjusted 
discount rate. Subsequent adjustments to these assumptions can cause changes to the measure of contingent consideration.
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; and (6) reviewing the funding and operating agreements. Examples of significant activities currently 
being performed by the Company’s significant consolidated and unconsolidated 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 
The Company performs a goodwill impairment test annually, on October 1st of each year and  additionally, performs a quarterly 
qualitative assessment to address whether a triggering event has occurred that would require an 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. 
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 

PARSONS CORPORATION AND SUBSIDIARIES 
Notes to Consolidated Financial Statements

F-18
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 sixteen 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 statement carrying amounts and tax basis of the 
Company’s assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to be in effect when the 
asset or liability is 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. 
New Accounting Pronouncements       
In the fourth quarter of 2024, The Financial Accounting Standards Board ("FASB") Issued Accounting Standards Update (“ASU”) 2024-
04, "Debt—Debt with Conversion and Other Options (Subtopic 470-20)" ("ASU 2024-04"). ASU 2024-04 improves the relevance and 
consistency in application of the induced conversion guidance in Subtopic 470-20, Debt–Debt with Conversion and Other Options. The 
amendments in ASU 2024-04 clarify the requirements for determining whether certain settlements of convertible debt instruments should be 
accounted for as an induced conversion. Under the amendments, to account for a settlement of a convertible debt instrument as an induced 
conversion, an inducement offer is required to provide the debt holder with, at a minimum, the consideration (in form and amount) issuable 
under the conversion privileges provided in the terms of the instrument. The amendments in this Update are effective for all entities for 
annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. Early 
adoption is permitted for all entities that have adopted the amendments in ASU 2020-06. The Company adopted ASU 2020-06 in the first 
quarter of 2021. The Company has elected to early adopt ASU 2024-04 as of January 1, 2024 on a prospective basis. The adoption of this 
ASU had a material impact on the Company's consolidated financial statements.
In the first quarter of 2024, the Company took an extinguishment charge related to the partial repurchase of Convertible Senior Notes 
due 2025. This repurchase was recorded in the Company's financial statements as a loss on debt extinguishment according to the applicable 
guidance prior to ASU 2024-04. With the early adoption of ASU 2024-04, the Company reassessed the accounting conclusion of the first 
quarter 2024 partial repurchase of Convertible Senior Notes due 2025 and concluded the partial repurchase is subject to inducement 
accounting under ASU 2024-04.
Under inducement accounting, the difference in the fair value of the securities issuable pursuant to conversion privileges compared to 
the fair value of the consideration paid on the date of the acceptance of the inducement offer is recorded to inducement expense. The 
difference in the consideration paid to note holders, less inducement expenses, less the fair value of the notes repurchased is charged to 
equity. 
For the year ended December 31, 2024, the Company reversed the loss on extinguishment of debt for the partial repurchase of the 
Convertible Senior Notes due 2025 and recorded the repurchase transaction as an induced conversion. This change from extinguishment to 
inducement accounting resulted in the Company (i.) reversing the $211.0 million loss and the related $49.9 million tax benefit on 
extinguishment of debt, recorded in Q1 2024, (ii.) recording a $18.4 million convertible debt repurchase loss, (iii.) the difference between the 
extinguishment loss and inducement expense of $192.6 million recorded to equity, and (iv.) the related tax benefit of $45.6 million recorded 
to equity. See "Note 11—Debt and Credit Facilities" for a further discussion of the first quarter 2024 extinguishment accounting and 
subsequent change to inducement accounting. Also see "Note 21—Quarterly Information" for the quarterly financial statement impacts 
related to this accounting change.
In the fourth quarter of 2024, The FASB Issued ASU 2024-03 "Income Statement—Reporting Comprehensive Income—Expense 
Disaggregation Disclosures (Subtopic 220-40)" (ASU 2024-03"). ASU 2024-03 requires disclosure, in the notes to financial statements, of 
specified information about certain costs and expenses. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 
2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The adoption of this ASU will not have a 
material impact on the Company's consolidated financial statements.

In the fourth quarter of 2023, The FASB Issued Accounting Standards Update (“ASU”) 2023-09, "Income Taxes (Topic 740)" ("ASU 
2023-09"). ASU 2023-09 enhances the transparency and decision usefulness of income tax disclosures. The amendments in ASU 2023-09 
addresses investor requests for more transparency about income tax information through improvements to income tax disclosures primarily 
related to the rate reconciliation and income taxes paid information. ASU 2023-09 also includes certain other amendments to improve the 
effectiveness of income tax disclosures. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. Early adoption is 
permitted. The adoption of this ASU will not have a material impact on the Company's consolidated financial statements.
In the fourth quarter of 2023, The FASB Issued ASU 2023-07, "Segment Reporting (Topic 280)". ASU 2023-07 introduces enhanced 
disclosures about significant segment expenses along with other enhanced segment disclosures. ASU 2023-07 is effective for fiscal years 
beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. 
The adoption of this ASU did not have a material impact on the Company's consolidated financial statements.
During July 2023, the FASB Issued ASU 2023-03. ASU 2023-03 incorporates, into certain accounting standards, amendments to SEC 
paragraphs pursuant to SEC Staff Accounting Bulletin No. 120, SEC Staff Announcement at the March 24, 2022 EITF meeting, and Staff 
Accounting Bulletin Topic 6.B, Accounting Series Release 280—General Revisions of Regulation S-X: Income or Loss Applicable to 
Common Stock. These rules are effective immediately. The adoption of this ASU will not have a material impact on the Company's 
consolidated financial statements.
In the first quarter of 2022, the Company early adopted ASU 2021-08, “Business Combinations (Topic 805) ("ASU 2021-08"): 
Accounting for Contract Assets and Contract Liabilities from Contracts with Customers”. The new guidance requires that the approach of 
ASC 606, Revenue from Contracts with Customers, should be used to measure an acquired revenue contract in a business combination. 
This guidance is to be applied (1) retrospectively to all business combinations for which the acquisition date occurs on or after the beginning 
of the fiscal year that includes the interim period of early application and (2) prospectively to all business combinations that occur on or after 
the date of initial application. The early adoption of ASU 2021-08 did not have a material impact on the Company's consolidated financial 
statements.

Transaction Price Allocated to the Remaining Unsatisfied Performance Obligations 
The Company’s remaining unsatisfied performance obligations (“RUPO”) as of December 31, 2024 represent a measure of the total 
dollar value of work to be performed on contracts awarded and in progress. The Company had $6.7 billion in RUPO as of December 31, 
2024. 
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. 
RUPO is comprised of: (a) original transaction price, (b) change orders for which written confirmations from our customers have been 
received, (c) pending change orders for which the Company expects to receive confirmatrions in the ordinary course of business, and (d) 
claim amounts that the Company has made against customers for which it has determined that it has a legal basis under existing contractual 
arrangements and a significant reversal of revenue is not probable, less revenue recognized to-date.

tax benefits of $8.9 million, $8.6 million, and $4.4 million for 2024, 2023 and 2022, respectively. The tax benefit realized related to awards 
vested during 2024, 2023, and 2022 was $12.0 million, $4.3 million, and $2.7 million, respectively. We recognize forfeitures as they occur.
At December 31, 2024, the amount of compensation cost relating to non-vested awards not yet recognized in the consolidated 
financial statements is $51.3 million. The majority of these unrecognized compensation costs will be recognized by the third quarter of fiscal 
2026.
Restricted Stock Units
Restricted Stock Units awards are issued under the Incentive Award Plan and are settled by the issuance of the Company’s common 
stock. Outstanding awards have been granted based on either service or service and performance conditions. Awards vest over three-year 
periods, either annually or cliff. Expense is recognized on an accelerated basis for awards with service conditions only and on a straight-line 
basis for awards that include performance conditions. Expense recognition of awards with performance criteria are subject to the probability 
of meeting the performance conditions and adjusted for the number of shares expected to be earned. Compensation cost for awards with 
performance conditions are trued-up at each reporting period for changes in the expected shares pro-rated for the portion of the requisite 
service period rendered.
The following table presents the number of shares of restricted stock units granted (at target shares for awards with performance 
conditions) for the years ended December 31, 2024, December 31, 2023 and December 31, 2022:

The number of shares ultimately issued, which could be greater or less than target, will be based on achieving specific performance 
conditions related to the awards. During the years ended December 31, 2024 and December 31, 2023, certain restricted stock unit grants 
with performance conditions vested with performance different from the target share amounts. As a result, 99,280 and 97,551 additional 
shares, respectively were granted and vested.

Delayed Draw Term Loan
In September 2022, the Company entered into a $350 million unsecured Delayed Draw Term Loan with an increase option of up to 
$150 million (the “2022 Delayed Draw Term Loan”). The 2022 Delayed Draw Term Loan may be borrowed in a single draw during the period 
from and including the Closing Date to the earlier to occur of (a) the date of termination of the 2022 Delayed Draw Term Loan by the 
Company pursuant to the terms of the 2022 Delayed Draw Term Loan Agreement and (b) six (6) months following the Closing Date. 
Proceeds of the 2022 Delayed Draw Term Loan Agreement may be used (a) to pay off in full, or partially payoff, the Company’s existing 
Senior Notes, (b) to prepay revolving loans outstanding under the Revolving Credit Agreement (as defined below), or (c) for working capital, 
capital expenditures and other lawful corporate purposes. The Company drew $350.0 million from the 2022 Delayed Draw Term Loan in 
November 2022. The Company incurred $0.9 million of debt issuance costs in connection with the delayed draw term loan as of December 
31, 2022. These costs are presented as a direct deduction from the debt on the face of the balance sheet. Interest expense related to the 
Delayed Draw Term Loan was $23.1million, $22.4 million and $3.3 million for the years ended December 31, 2024, December 31, 2023 and 
December 31, 2022 respectively. The amortization of debt issuance costs and interest expense is recorded in “Interest expense” on the 
consolidated statements of income. As of December 31, 2024 and December 31, 2023, there was $350.0 million outstanding under the 
Delayed Draw Term Loan. 
The 2022 Delayed Draw Term Loan has a three-year maturity and permits the Company to borrow in U.S. dollars. The 2022 Delayed 
Draw Term Loan does not require any amortization payments by the Company. Depending on the Company’s consolidated leverage ratio (or 
debt rating after such time as the Company has such rating), borrowings under the 2022 Delayed Draw Term Loan Agreement will bear 
interest at either an adjusted Term SOFR benchmark rate plus a margin between 0.875% and 1.500% or a base rate plus a margin of 
between 0% and 0.500% and will initially bear interest at the middle of this range. The Company will pay a ticking fee on unused term loan 
commitments at a rate of 0.175% commencing with the date that is ninety (90) days after the Closing Date. Amounts outstanding under the 
2022 Delayed Draw Term Loan Agreement may be prepaid at the option of the Company without premium or penalty, subject to customary 
breakage fees in connection with the prepayment of benchmark rate loans. The interest rates on December 31, 2024 and December 31, 
2023 were 5.6% and 6.6%, respectively.
Convertible Senior Notes due 2025
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. 

PARSONS CORPORATION AND SUBSIDIARIES 
Notes to Consolidated Financial Statements

F-38
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 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.
The Company recognized interest expense of $3.9 million, $3.1 million and $3.0 million for the years ended December 31, 2024. 
December 31, 2023 and December 31, 2022, respectively. As of December 31, 2024 and December 31, 2023 the net carrying value of the 
Convertible Senior Notes due 2025 were $113.4 million and $396.5 million, respectively. 
See the discussion of the partial repurchase of Convertible Senior Notes due 2025 and the unwind of the related note hedge and 
warrants below.      
Note Hedge and Warrant - Convertible Senior Notes due 2025
In connection with the sale of the Convertible Senior Notes, the Company purchased a bond hedge designed to mitigate the potential 
dilution from the conversion of the Convertible Senior Notes. 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.
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 
the capitalized debt issuance costs. The Company also recorded a deferred tax asset of $16.5 million related to the convertible note hedge 
transactions and the tax basis of the capitalized debt issuance costs through additional paid-in capital. The deferred tax liability and deferred 
tax asset were included net in “Deferred tax assets” on the consolidated balance sheets. Upon adoption of ASU 2020-06, the Company 
reversed the deferred tax liability of $13.9 million that the Company had recorded at issuance related to the Convertible Senior Note debt 
discount and recorded an additional deferred tax liability of $0.4 million related to the capitalized debt issuance costs. In addition, the 
Company recorded a $0.9 million adjustment to the deferred tax asset through retained earnings related to the tax effect of book accretion 
recorded in 2020 and reversed upon adoption.
Convertible Senior Notes due 2029
In February 2024, the Company issued an aggregate $800.0 million of 2.625% Convertible Senior Notes due 2029 (the “2029 
Convertible Notes”), including the exercise of a $100.0 million initial purchasers’ option in full. The Company received proceeds from the 
issuance and sale of the 2029 Convertible Notes of $781.1 million, net of $18.9 million of transaction fees and other third-party offering 
expenses. The 2029 Convertible Notes accrue interest at a rate of 2.625% per annum, payable semi-annually on March 1 and September 1 
of each year beginning on September 1, 2024, and will mature on March 1, 2029, unless earlier repurchased, redeemed or converted. 
The 2029 Convertible 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 2029 Convertible 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, including borrowings under the Company’s revolving credit facility and delayed draw term loan credit facility, 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 2029 Convertible Notes will initially be convertible into 10.6256 shares of our common stock, which is 
equivalent to an initial conversion price of approximately $94.11 per share, subject to adjustment upon the occurrence of specified events. 
On or after October 1, 2028 until the close of business on the second scheduled trading day immediately preceding the maturity date of the 
2029 Convertible Notes, holders may convert all or a portion of their 2029 Convertible Notes, regardless of the conditions below.

Prior to the close of business on the business day immediately preceding October 1, 2028, the 2029 Convertible 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 June 30, 2024, 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 ten consecutive trading day period in which, for each trading day of that 
period, the trading price per $1,000 principal amount of 2029 Convertible 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 2029 Convertible 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 2029 Convertible Notes for cash, at its option, on or after March 8, 2027 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 2029 Convertible 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 2029 Convertible 
Notes for redemption will constitute a Make-Whole Fundamental Change with respect to that 2029 Convertible Note, in which case the 
conversion rate applicable to the conversion of that 2029 Convertible Notes 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 2029 Convertible Notes, holders of the 2029 
Convertible Notes may require the Company to repurchase all or a portion of the 2029 Convertible Notes for cash at a price equal to 100% of 
the principal amount of the 2029 Convertible Notes to be repurchased, plus any accrued and unpaid interest to, but excluding, the 
fundamental change repurchase date.
Upon conversion, the Company will settle the principal amount of the 2029 Convertible Notes converted in cash and will settle the 
remainder of the consideration owed upon conversion in cash, shares of the Company’s common stock, or a combination thereof, at the 
Company’s option, with such amount of cash and, if applicable, shares of common stock due upon conversion based on a daily conversion 
value calculated on a proportionate basis for each trading day in a 50-trading day observation period.
The Company recognized interest expense with respect to the 2029 Convertible Notes of $21.3 million for the year ended December 
31, 2024. As of December 31, 2024, the net carrying value of the 2029 Convertible Notes due 2029 was $784.3 million. 
Capped Call Transactions - Convertible Senior Notes due 2029
In February 2024, in connection with the offering of the 2029 Convertible Notes, the Company entered into capped call transactions 
(the “Capped Call Transactions”) with certain financial institutions. The Capped Call Transactions are expected generally to reduce the 
potential dilution to the Company’s common stock upon any conversion of the Convertible Senior Notes due 2029 and/or offset any cash 
payments the Company is required to make in excess of the principal amount of any converted 

PARSONS CORPORATION AND SUBSIDIARIES 
Notes to Consolidated Financial Statements 
December 31, 2024, December 31, 2023 and December 31, 2022 
 
 
F-41
Convertible Senior Notes due 2029, as the case may be. If, however, the market price per share of the Company’s common stock, as 
measured under the terms of the Capped Call Transactions, exceeds the cap price of the Capped Call Transactions, there would 
nevertheless be dilution and/or there would not be an offset of such cash payments, in each case, to the extent that such market price 
exceeds the cap price of the Capped Call Transactions.
The cap price of the Capped Call Transactions is initially $131.7575 per share, which represents a premium of 75% over the last 
reported sale price of the Company’s common stock of $75.29 per share on the New York Stock Exchange on February 21, 2024, and is 
subject to certain adjustments under the terms of the Capped Call Transactions. The cost of $88.4 million for the Capped Call Transactions 
was recorded as a reduction to additional paid-in capital in the consolidated balance sheets.
At issuance, the Company recorded a deferred tax asset of $22.3 million related to the Capped Call Transactions costs through 
additional paid-in capital. The deferred tax asset was included in Deferred tax assets in the consolidated balance sheets. 
Convertible Senior Notes due 2025 Partial Repurchase and Note Hedge and Warrants Partial Unwind
In connection with the issuance of the Convertible Senior Notes due 2029, during the first quarter of 2024, we used $391.8 million of 
the net proceeds to purchase approximately $228.1 million aggregate principal amount of our Convertible Senior Notes due 2025 
concurrently with the offering in separate and individually negotiated transactions. In addition, we used $103.8 million to settle the repurchase 
of approximately $56.5 million aggregate principal amount of our Convertible Senior Notes due 2025 in a separately negotiated transaction 
that settled in March 2024. We also received approximately $90.6 million in cash from the note hedge counterparties for the partial 
termination of the existing bond hedge relating to the Convertible Senior Notes due 2025 repurchased, net of our obligations to the 
counterparties in connection with the partial termination of the related warrant transactions. The tax effect of $46.2 million from the partial 
unwind of the existing bond hedge was recognized as a reduction in additional paid-in capital in the consolidated balance sheets. The 
income tax payable was included in Income taxes payable in the consolidated balance sheets.
The partial repurchase, during the year ended December 31, 2024, resulted in a $18.4 million repurchase loss1 and a $3.2 million 
charge to interest expense for the acceleration of the amortization of debt issuance costs associated with the 0.25% Convertible Senior 
Notes due 2025. The tax effect of the repurchase loss, excluding the interest expense, was recognized as a discrete event during the year 
with a tax benefit of $4.3 million recognized in the income statement.
1During the first quarter of 2024, prior to the early adoption of ASU 2024-04, the Company recorded a $211.0 million loss on debt extinguishment 
associated with the 0.25% Convertible Senior Notes due 2025. The tax effect of the debt extinguishment, excluding the interest expense, was 
recognized as a discrete event to the quarter giving rise to an increase in the effective tax rate and tax benefit of $49.9 million recognized in the 
income statement. Please see "Note 2—Summary of Significant Accounting Policies—New Accounting Pronouncements" for a discussion of the 
Company's adoption of ASU 2024-04. The extinguishment charge and related income tax impacts were reversed from the Company's consolidated 
financial statements and recorded as a convertible debt repurchase loss as described above.
Revolving Credit Facility
In June 2021, the Company entered into a $650 million unsecured revolving credit facility (the “Credit Agreement”). The Company 
incurred $1.9 million of costs in connection with this Credit Agreement. The 2021 Credit Agreement replaced an existing Fifth Amended and 
Restated Credit Agreement dated as of November 15, 2017. Under the new agreement, the Company’s revolving credit facility was 
increased from $550 million to $650 million. The credit facility has a five-year maturity, which may be extended up to two times for periods 
determined by the Company and the applicable extending lenders, and permits the Company to borrow in U.S. dollars, certain specified 
foreign currencies, and

each other currency that may be approved in accordance with the 2021 Facility. The borrowings under the Credit Agreement bear interest at 
either a eurocurrency rate plus a margin between 1.0% and 1.625% or a base rate (as defined in the Credit Agreement) plus a margin of 
between 0% and 0.625%. The rates on December 31, 2024 and December 31, 2023 were 5.7% and 6.7%, respectively. Borrowings under 
this Credit Agreement are guaranteed by certain Company operating subsidiaries. Letters of credit commitments outstanding under this 
agreement aggregated approximately $43.0 million and $43.8 million at December 31, 2024 and December 31, 2023, respectively, which 
reduced borrowing limits available to the Company. Interest expense related to the Credit Agreement was $0.7 million, $3.9 million and $4.3 
million, for the years ended December 31, 2024, December 31, 2023 and December 31, 2022, respectively. There were no loan amounts 
outstanding under the Credit Agreement at December 31, 2024 and December 31, 2023.
The Credit Agreement 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, 2024 and December 31, 2023. 
Letters of Credit
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 $328.4 million and $320.7 million at December 31, 2024 and December 31, 2023, respectively.

The effective tax rate in 2024 decreased to 20.9% from 21.3% in 2023. The change in the effective tax rate was due primarily to tax 
benefits related to increases in the foreign-derived intangible income (FDII) deduction and increased equity-based compensation deductions, 
partially offset by an increase in valuation allowance on NOLs and non-deductible executive compensation subject to Section 162(m).
The effective tax rate in 2023 decreased to 21.3% from 23.9% in 2022. The change in the effective tax rate was due primarily to tax 
benefits related to increases in the foreign-derived intangible income (FDII) deduction and a change in jurisdictional mix of earnings, partially 
offset by an increase in valuation allowance on foreign tax credits originating from foreign withholding taxes.
The effective tax rate for the year ended December 31, 2024 differs from the federal statutory tax rate of 21% primarily due to state 
income taxes, valuation allowance and executive compensation subject to Section 162(m), offset by benefits related to untaxed income 
attributable to noncontrolling interests, earnings in lower tax jurisdictions, the FDII deduction, and equity-based compensation deductions.

The Company is not asserting that any of the earnings of the foreign subsidiaries will be permanently reinvested. Therefore, the 
Company has recorded a deferred tax liability for the undistributed earnings net of applicable foreign tax credits.
The Company assesses the realizability of its deferred tax assets each reporting period through an analysis of potential sources of 
taxable income, including prior year taxable income available to absorb carryback of tax losses, reversals of existing taxable temporary 
differences, tax planning strategies, and forecasts of taxable income. 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.
As of December 31, 2024, and December 31, 2023, the Company’s valuation allowance against deferred tax assets was $45.3 million 
and $34.8 million, respectively. The Company has recorded a valuation allowance against certain tax attributes that the Company has 
determined are not more-likely-than-not to be realized, including certain foreign net operating loss carryforwards, foreign tax credit 
carryforwards, and capital loss carryforwards. From December 31, 2023 to December 31, 2024, the Company’s valuation allowance 
increased by $10.5 million. This increase relates to deferred tax assets recorded for net operating loss carryforwards and foreign tax credit 
carryforwards. The valuation allowance is recorded because the Company does not expect to have sufficient taxable income and

foreign source income to utilize the net operating loss carryforwards and the foreign tax credit carryforwards before they expire.
As of December 31, 2024, the Company has Net Operating Losses ("NOLs") of $1.7 million, $20.3 million, and $74.2 million for U.S. 
Federal, U.S. states and foreign jurisdictions, respectively. The utilization of the U.S. federal and U.S. state NOLs are subject to certain 
annual limitations. Of these NOL amounts, $1.7 million, $8.0 million and $12.9 million in U.S. Federal, 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 2025 
and 2045.
As of December 31, 2024, the Company has foreign tax credit carryforwards of $33.5 million. The Company has provided a valuation 
allowance of $33.5 million as the Company considers it is not more likely than not that these credits will be realized. These foreign tax credits 
start expiring in the year 2029.

At December 31, 2024, and December 31, 2023, there are $28.6 million and $25.1 million of unrecognized tax benefits that if 
recognized would affect the Company’s effective tax rate.
The Company recognizes interest and penalties related to unrecognized tax benefits as part of its income tax expense. During the 
years ended December 31, 2024, December 31, 2023, and December 31, 2022, the Company recognized approximately $1 million, $0.5 
million, and $0.7 million in interest and penalties, respectively, in the consolidated statements of income. The total amount of interest and 
penalties accrued in the consolidated balance sheets was $5.6 million, $4.6 million, and $4.1 million as of December 31, 2024, December 31, 
2023, and December 31, 2022, respectively.
The Company conducts business globally and, as a result, the Company or one or more of its subsidiaries files 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 jurisdictions where the Company has significant activities, such as Canada, Qatar, Saudi Arabia and the United 
States. As of December 31, 2024, the Company’s U.S. federal income tax returns for tax years 2021 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 $7.2 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.

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 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 unless some amount within the range of loss 
appears at that time to be a better estimate than any other amount in 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. 
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. The court heard dispositive 
motions in 2023, including Parsons’ motion for summary judgment. We are awaiting the court’s rulings upon such motions, which will 
determine whether a trial will be necessary for this matter in 2025.
On July 1, 2024, a final judgment was filed with the clerk of the Superior Court of the State of California In and For the County of San 
Mateo with an award of damages in the total amount of approximately $102.5 million in favor of Parsons Transportation Group, Inc. and 
against Alstom Signaling Operations LLC (Alstom"). This proposed award relates back to a lawsuit Parsons initially filed against the 
Peninsula Corridor Joint Powers Board for breach of contract and wrongful termination in February 2017 (which was settled between 
Parsons and the Joint Powers Board in 2021) and a cross-complaint filed against Alstom Signaling Operations LLC in November 2017, as 
subsequently amended, for breach of contract, negligence and intentional misrepresentation. On September 23, 2024, the Court awarded 
pre-judgment interest in the amount of $34.0 million and amended the judgment accordingly to include such interest. Alstom filed a Notice of 
Appeal and has posted a bond as required under California law.
At this time, the Company is unable to determine the probability of the outcome of the litigation.
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 Federal Acquisition Regulations (“FAR”). If the DCAA determines we have not 
accounted for such costs in accordance with the FAR, 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 2014 have been 
closed, and years thereafter remain open. All of Parsons operating systems have been deemed adequate by the U.S. federal government.
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.
15.
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 three 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, 2024, the total shares of the Company’s common stock outstanding were 106,775,350, of which 54,117,903 
were held by the ESOP. As of December 31, 2023, the total shares of the Company’s common stock outstanding were 105,839,978, of which 
59,879,857 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 $59.8 million, $58.2 million and $54.7 million for the years ended December 31, 
2024, December 31, 2023 and December 31, 2022, respectively, and is recorded in “Direct costs of contracts” and “Selling, general and 
administrative expense” in the consolidated statements of income.
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, 2024, December 31, 2023 and December 31, 2022 amounted to $37.7 million, $35.4 million, and $30.2 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, 2024 and December 31, 2023, the defined benefit pension plan was in a net asset 
position of $1.3 million and $1.4 million, respectively, which is recorded in “Other noncurrent assets” on the consolidated balance sheets.
16.	 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 

PARSONS CORPORATION AND SUBSIDIARIES 
Notes to Consolidated Financial Statements 
December 31, 2024, December 31, 2023 and December 31, 2022 
 
 
F-48
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 11—Debt and Credit Facilities” that relate to project ventures are approximately $176.7 
million and $147.7 million at December 31, 2024 and December 31, 2023, 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.

The assets of the consolidated joint ventures are restricted for use only by the particular joint venture and are not available for the 
Company’s general operations. 
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.

Fair Value 
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, 2024 and December 31, 2023 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 assumptions to determine the fair value of certain financial instruments could result in a 
different fair value measurement at the reporting date. 
Financial assets and liabilities measured at fair value on a recurring basis are as follows:

As described in “Note 15—Retirement and Other Benefits Plans”, the Company acquired a defined contribution pension plan, a 
defined benefit pension plan, and supplemental retirement plans. At December 31, 2024 and December 31, 2023, 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. 
In determining the fair value of acquired intangible assets from our business acquisitions, the Company uses the multi-period excess 
earnings method to value customer relationships and backlog and values developed technologies using the relief-from royalty method. These 
valuation methods use significant unobservable inputs classified within Level 3 of the fair value hierarchy. See "Note 2—Summary of 
Significant Accounting Policies."
We measure contingent consideration at fair value on a recurring basis using significant unobservable inputs classified within Level 3 
of the fair value hierarchy. See "Note 2—Summary of Significant Accounting Policies" and "Note 3—Acquisitions" for further information.
With respect to equity-based compensation, for restricted stock units containing service conditions or service and performance 
conditions, the grant date 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. For awards that include market conditions, the grant date fair value is determined using a Monte Carlo simulation.
The carrying values and estimated fair values of our financial instruments that are not required to be recorded at fair value in our 
consolidated balance sheets, on the basis of Level 1 inputs for the Company's convertible notes and Level 2 inputs for the delayed draw term 
loan, were as follows (in thousands):

Earnings Per Share 
Basic earnings per share (“EPS”) is computed using the weighted average number of shares outstanding during the period and income 
available to shareholders. Diluted EPS includes additional common shares that would have been outstanding if potential common shares 
with a dilutive effect had been issued using the if-converted method for Convertible Debt and the treasury stock method for all other 
instruments. 
Under the treasury stock method, the weighted average number of shares outstanding is adjusted to reflect the dilutive effects of 
stock-based awards and shares underlying the warrants related to the convertible senior notes due 2025.
Under the if-converted method:
1.
Convertible Senior Notes due 2025:
a.
Income available to shareholders is adjusted to add back interest expense, after tax (unless antidilutive).
b.
Weighted average number of shares outstanding is adjusted to include the shares underlying the convertible debt (unless 
antidilutive).
c.
Shares underlying the bond hedge (unless antidilutive).
2.
Convertible Senior Notes due 2029:
a.
Interest has been excluded from the numerator and no shares have been included in the denominator of diluted EPS, as 
the principal amount of convertible debt will be settled in cash with any excess conversion value settled in cash or shares 
of common stock.
b.
Excludes shares underlying the capped call as the shares are antidilutive.

having an aggregate market value of not greater than $100 million from time to time, commencing on August 12, 2021. The Board further 
amended this authorization in August 2022 to remove the prior expiration date and grant executive leadership the discretion to determine the 
price for such share repurchases. The Board further amended this authorization in February 2024 to restore the repurchase capacity to $100 
million and removed the $25 million quarterly cap on such repurchases. 
At the time of the February 2024 authorization, the Company had repurchased shares with an aggregated market value (including 
fees) of $54.7 million. The aggregate market value of shares of Common Stock the Company is authorized to acquire, from both the August 
2021 and February 2024 authorizations, is not greater than $154.7 million. 
As of December 31, 2024, the Company has $75 million remaining under the stock repurchase program. 
Repurchased shares of common stock are retired and included in “Repurchases of common stock” in cash flows from financing 
activities in the Consolidated Statements of Cash Flows. The primary purpose of the Company’s share repurchase program is to reduce the 
dilutive effect of shares issued under the Company’s ESOP and other stock benefit plans. The timing, amount and manner of share 
repurchases may depend upon market conditions and economic circumstances, availability of investment opportunities, the availability and 
costs of financing, the market price of the Company's common stock, other uses of capital and other factors.
The following table summarizes the repurchase activity under the stock repurchase program.

Segments Information 
The Company operates in two reportable segments: Federal Solutions and Critical Infrastructure. 
The Federal Solutions segment provides advanced technical solutions to the U.S. government, delivering timely, cost-effective 
hardware, software and services for mission-critical projects. The segment provides advanced technologies, supporting national security 
missions in cyber operations, missile defense, and military facility modernization, logistics support, hazardous material remediation and 
engineering services. 
The Critical Infrastructure segment provides integrated engineering and management services for complex physical and digital 
infrastructure around the globe. The Critical Infrastructure segment is a technology innovator focused on next generation digital systems and 
complex structures. Industry leading capabilities in engineering and project management allow the Company to deliver significant value to 
customers by employing cutting-edge technologies, improving timelines and reducing costs.
The Company defines its reportable segments based on the way the chief operating decision maker (“CODM”), its Chief Executive 
Officer, evaluates the performance of each segment and manages the operations of the Company for purposes of allocating resources 
among the segments. The CODM

evaluates segment operating performance using segment Revenue, segment direct cost of contracts, segment Selling, General and 
Administrative expense and segment Adjusted EBITDA attributable to Parsons Corporation. 
 
The Company defines Adjusted EBITDA attributable to Parsons Corporation as Adjusted EBITDA excluding Adjusted EBITDA 
attributable to noncontrolling interests. The Company defines Adjusted EBITDA as net income (loss) attributable to Parsons Corporation, 
adjusted to include net income (loss) 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 are not considered in the evaluation of ongoing 
operating performance. These other items include net income (loss) attributable to noncontrolling interests, asset impairment charges, 
income and expense recognized on litigation matters, expenses incurred in connection with acquisitions and other non-recurring transaction 
costs and expenses related to our prior restructuring. 
 
Adjusted EBITDA is the measure of our operating performance used by the CODM to assess our segments’ financial performance. 
The CODM uses Adjusted EBITDA for business planning purposes, including to manage our segments against internal projected results of 
operations and measure the performance of our segments generally.
 
The following tables present segment information provided to the CODM, as of each fiscal year presented, along with a reconciliation 
of segment adjusted EBITDA attributable to Parsons Corporation to net income attributable to Parsons Corporation for the periods presented

1 Presents the revised quarterly financial data resulting from the adoption of Accounting Standards Update (“ASU”) 2024-04 as of January 1, 2024 on 
a prospective basis. As a result of the adoption of ASU 2024-04, the Company reversed a loss on extinguishment of debt for the partial repurchase of the 
Convertible Senior Notes due 2025 and recorded the repurchase transaction as an induced conversion. This change from extinguishment to inducement 
accounting resulted in the Company (i.) reversing the $211.0 million loss and the related $49.9 million tax benefit on extinguishment of debt, recorded in Q1 
2024, (ii.) recording a $18.4 million convertible debt repurchase loss, (iii.) the difference between the extinguishment loss and inducement expense of $192.6 
million recorded to equity, and (iv.) the related tax benefit of $45.6 million recorded to equity. See "Note 2—Summary of Significant Accounting Polices—
New Accounting Pronouncements" for a further discussion of the first quarter 2024 extinguishment accounting and subsequent change to inducement 
accounting.
2 Diluted earnings per share prior to the adoption of ASU 2024-04 did not include certain adjustments as their inclusion would have been antidilutive. 
Subsequent to the adoption of ASU 2024-04 these adjustments are no longer antidilutive. Dilutive adjustments include if converted interest of $2.8 million, 
1.5 million shares related to stock based awards and 6.8 million shares related to convertible senior notes. Inclusion of these dilution adjustments resulted in 
dilutive net income attributable to Parsons Corporation of $42.5 million and total diluted shares of 114.4 million for the quarter ended March 31, 2024.

Subsequent Events
After the year ended December 31, 2024, the Company entered into a merger agreement to acquire a 100% ownership interest in TRS 
Group, Inc. ("TRS") for approximately $36 million from cash on hand. Headquartered in Indianapolis, Indiana, TRS is an environmental 
solutions firm that specializes in remediation technology. At the time of the filing of this Form 10-K, the Company has just started the process 
of obtaining the relevant data to make the required acquisition related disclosures. This acquisition is not material to the Company's 
consolidated financial statements.
