Clients

We provide services to a diverse base of U.S. federal government, U.S. state and local government, U.S. commercial and international clients. The following table presents the percentage of our revenue by client sector:

Fiscal Year

U.S. state and local government 11.8 13.4 17.2

(1) Includes revenue generated under U.S. federal government contracts performed outside the United States.

(2) Includes revenue generated from non-U.S. clients, primarily in the United Kingdom, Australia and Canada.

U.S. federal government agencies are significant clients. The U.S. Agency for International Development accounted for 13.0%, 12.2% and 11.0% of our revenue in fiscal 2024, 2023 and 2022, respectively. The Department of Defense ("DoD") accounted for 8.5%, 8.9% and 9.7% of our revenue in fiscal 2024, 2023 and 2022, respectively. We typically support multiple programs within a single U.S. federal government agency, both domestically and internationally. We also assist U.S. state and local government clients in various jurisdictions across the United States. Our international clients are primarily focused in Canada, Australia, Europe and the United Kingdom, and consist of a relatively equal sized mix of government and commercial clients. Our U.S. commercial clients include companies in the chemical, energy, pharmaceutical, retail, aerospace and automotive industries. No single client, except for the U.S. federal government clients, accounted for more than 10% of our revenue in fiscal 2024.

Contracts

Our services are performed under three principal types of contracts with our clients: fixed-price, time-and-materials and cost-plus. The following table presents the percentage of our revenue by contract type:

Fiscal Year

Under a fixed-price contract, clients agree to pay a specified price for our performance of the entire contract or a specified portion of the contract. Some fixed-price contracts can include date-certain and/or performance obligations. Fixed-price contracts carry certain inherent risks, including risks of losses from underestimating costs, delays in project completion, problems with new technologies, price increases for materials and economic and other changes that may occur over the contract period. Consequently, the profitability of fixed-price contracts may vary substantially. Under time-and-materials contracts, we are paid for labor at negotiated hourly billing rates and paid for other expenses. Profitability on these contracts is driven by billable headcount and cost control. Many of our time-and-materials contracts are subject to maximum contract values and, accordingly, revenue related to these contracts is recognized as if these contracts were fixed-price contracts. Under our cost-plus contracts, some of which are subject to a contract ceiling amount, we are reimbursed for allowable costs and fees, which may be fixed or performance-based. If our costs exceed the contract ceiling or are not allowable, we may not be able to obtain full reimbursement. Further, the amount of the fee received for a cost-plus award fee contract partially depends upon the client's discretionary periodic assessment of our performance on that contract.

Some contracts with the U.S. federal government are subject to annual funding approval. U.S. federal government agencies may impose spending restrictions that limit the continued funding of our existing contracts and may limit our ability to obtain additional contracts. These limitations, if significant, could have a material adverse effect on us. All contracts with the U.S. federal government may be terminated by the government at any time, with or without cause.

U.S. federal government agencies have formal policies against continuing or awarding contracts that would create actual or potential conflicts of interest with other activities of a contractor. These policies may prevent us from bidding for or performing government contracts resulting from or related to certain work we have performed. In addition, services performed for a commercial or government sector client may create conflicts of interest that preclude or limit our ability to obtain work for a private organization. We attempt to identify actual or potential conflicts of interest and to minimize the possibility that such conflicts could affect our work under current contracts or our ability to compete for future contracts. We have, on occasion, declined to bid on a project because of an existing or potential conflict of interest.

Some of our operating units have contracts with the U.S. federal government that are subject to audit by the government, primarily the Defense Contract Audit Agency ("DCAA"). The DCAA generally seeks to (i) identify and evaluate all activities that contribute to, or have an impact on, proposed or incurred costs of government contracts; (ii) evaluate a contractor's policies, procedures, controls and performance; and (iii) prevent or avoid wasteful, careless and inefficient production or service. To accomplish this, the DCAA examines our internal control systems, management policies and financial capability; evaluates the accuracy, reliability and reasonableness of our cost representations and records; and assesses our compliance with Cost Accounting Standards ("CAS") and defective-pricing clauses found within the Federal Acquisition Regulation ("FAR"). The DCAA also performs an annual review of our overhead rates and assists in the establishment of our final rates. This review focuses on the allowability of cost items and the applicability of CAS. The DCAA also audits cost-based contracts, including the close-out of those contracts.

The DCAA reviews all types of U.S. federal government proposals, including those of award, administration, modification and re-pricing. The DCAA considers our cost accounting system, estimating methods and procedures and specific proposal requirements. Operational audits are also performed by the DCAA. A review of our operations at every major organizational level is conducted during the proposal review period. During the course of its audit, the U.S. federal government may disallow certain costs if it determines that we accounted for such costs in a manner inconsistent with CAS. Under a government contract, only those costs that are reasonable, allocable and allowable are recoverable. A disallowance of costs by the U.S. federal government could have a material adverse effect on our financial results.

In accordance with our corporate policies, we maintain controls to minimize any occurrence of fraud or other unlawful activities that could result in severe legal remedies, including the payment of damages and/or penalties, criminal and civil sanctions and debarment. In addition, we maintain preventative audit programs and mitigation measures to ensure that appropriate control systems are in place.

8

We provide services under contracts, purchase orders or retainer letters. Our policy requires that all contracts must be in writing. We bill our clients in accordance with the contract terms and periodically based on costs incurred, on either an hourly-fee basis or on a percentage-of-completion basis, as the project progresses. Most of our agreements permit our clients to terminate the agreements without cause upon payment of fees and expenses through the date of the termination. Generally, our contracts do not require that we provide performance bonds. If required, a performance bond, issued by a surety company, guarantees a contractor's performance under the contract. If the contractor defaults under the contract, the surety will, at its discretion, complete the job or pay the client the amount of the bond. If the contractor does not have a performance bond and defaults in the performance of a contract, the contractor is responsible for all damages resulting from the breach of contract. These damages include the cost of completion, together with possible consequential damages such as lost profits.

Growth Strategy

Our management team establishes Tetra Tech's overall business strategy. Our strategic plan defines and guides our investment in marketing and business development to leverage our differentiators and target priority programs and growth markets.

To support our growth plans, we actively attract, recruit, engage and retain key hires. Our combination of high-end science, technology resources and consulting culture coupled with practical applications provides challenging and rewarding opportunities for our workforce, thereby enhancing our ability to recruit and retain top quality talent. Our internal networking programs, leadership training, entrepreneurial environment, focus on Leading with Science® and global project portfolio help to attract and retain highly qualified individuals.

Our strategic growth plans are augmented by our selective investment in acquisitions aligned with our business. Acquisitions advance our strategy by adding new technologies, broadening our service offerings, adding contract capacity and expanding our geographic presence. Our long-established experience in identifying and integrating acquisitions strengthens our ability to integrate and rapidly leverage the resources of the acquired companies post-acquisition.

Sustainability Program

Sustainability is an integral part of our global business, rooted in our internal culture and extending throughout our projects around the world. For more than 50 years, we have leveraged cutting-edge expertise and the latest technology to deliver more sustainable solutions to clients and continually improve the way we do business.

Through our Sustainability Program, we monitor environmental, social and governance ("ESG") metrics, including human capital elements. We continue to enhance the sustainability of our daily practices, reduce our GHG emissions, and provide an exceptional working environment for our employees across our global operations. As a signatory of the United Nations ("UN") Global Compact on human rights, labor, environment and anti-corruption, we embrace the UN Global Compact's Ten Principles as part of the strategy, culture and daily operations of our company.

We actively engage with our stakeholders, internally and externally, to encourage input on the materiality of various ESG issues to Tetra Tech and have incorporated input into our double materiality analysis and sustainability program. Our

9

annual sustainability reporting and key metrics are aligned with the priorities we have set on ethics, human capital, professional development, and health & safety. We report on human capital metrics, including gender balance, racial and ethnic diversity in our workforce, employee engagement and professional development. We have supplier programs that integrate and emphasize sustainability in the procurement of goods and services and subcontracting for our projects. We have reported annually on GHG emissions for more than a decade, significantly reducing our emissions from program inception. In 2021, we expanded our reporting and set new goals for scope 1, 2, and 3 emissions. Based on input from stakeholders and in recognition of the importance of the project work we perform each year, in 2021 we also initiated our Billion People Challenge, with the overarching goal to improve the lives of one billion people by 2030. The Billion People Challenge progress is evaluated each year based on our annual project impact analysis in five categories that are closely aligned with the Global Reporting Initiative standards and the UN Sustainable Development Goals.

Our Sustainability Program is led by our Chief Sustainability Officer, who has been appointed by our Board of Directors and is supported by corporate and operations representatives through our Sustainability Council. We continuously review sustainability-related policies and practices, integrate input from stakeholders, and assess the results of our efforts in order to make future improvements. Tetra Tech's Board of Directors reviews and approves the Sustainability Program and evaluates our progress in achieving the goals and objectives outlined in our plan. As part of our membership in the UN Global Compact, we annually report on the Communication on Progress using Tetra Tech's Sustainability Report.

Acquisitions and Divestitures

Acquisitions. We continuously evaluate the marketplace for acquisition opportunities to further our strategic growth plans. Due to our reputation, size, financial resources, geographic presence and range of services, we have numerous opportunities to acquire privately and publicly held companies or selected portions of such companies. We evaluate an acquisition opportunity based on its ability to strengthen our leadership in the markets we serve, the technologies and solutions they provide and the additional new geographies and clients they bring. Also, during our evaluation, we examine an acquisition's ability to drive organic growth, its accretive effect on long-term earnings and its ability to generate return on investment. Generally, we proceed with an acquisition if we believe that it will strategically expand our service offerings, improve our long-term financial performance and increase shareholder returns.

We view acquisitions as a key component in the execution of our growth strategy, and we intend to use cash, debt or equity, as we deem appropriate, to fund acquisitions. We may acquire other businesses that we believe are synergistic and will ultimately increase our revenue and net income, strengthen our ability to achieve our strategic goals, provide critical mass with existing clients and further expand our lines of service. We typically pay a purchase price that results in the recognition of goodwill, generally representing the intangible value of a successful business with an assembled workforce specialized in our areas of interest. Acquisitions are inherently risky, and no assurance can be given that our previous or future acquisitions will be successful or will not have a material adverse effect on our financial position, results of operations or cash flows. All acquisitions require the approval of our Board of Directors.

In the second quarter of fiscal 2024, we acquired LS Technologies ("LST"), an innovative U.S. federal enterprise technology services and management consulting firm based in Fairfax, Virginia. LST provides high-end consulting and engineering services including advanced data analytics, cybersecurity and digital transformation solutions to U.S. government clients.In the third quarter of fiscal 2024, we also acquired Convergence Controls & Engineering ("CCE"), an industry leader in process automation and systems integration solutions. CCE’s expertise includes customized digital controls and software solutions, advanced data analytics, cloud data integration and cybersecurity applications. Both LST and CCE are included in our GSG segment.

In the second quarter of fiscal 2023, we completed the acquisition of RPS Group plc ("RPS"), a publicly traded company on the London Stock Exchange in an all-cash transaction totaling $784 million. We funded the RPS acquisition with debt, net of $109 million in proceeds from a foreign exchange forward contract that we entered into at the same time we made the formal offer to acquire RPS on September 23, 2022. RPS employs approximately 5,000 associates in the United Kingdom, Europe, Asia Pacific and North America, delivering high-end solutions, especially in energy transformation, water and program management for government and commercial clients. Substantially all of RPS is included in our CIG segment.

In the second quarter of fiscal 2023, we also acquired Amyx, Inc. (“Amyx”), an enterprise technology services, cybersecurity and management consulting firm based in Reston, Virginia. With over 500 employees, Amyx provides application modernization, cybersecurity, systems engineering, financial management and program management support on over 30 U.S. federal government programs. Amyx is included in our GSG segment.

For detailed information regarding acquisitions, see Note 5, "Acquisitions" of the "Notes to Consolidated Financial Statements" included in Item 8.

Divestitures. We regularly review and evaluate our existing operations to determine whether our business model should change through the divestiture of certain businesses. Accordingly, from time to time, we may divest or wind-down certain non-core businesses and reallocate our resources to businesses that better align with our long-term strategic direction. In

10

the fourth quarter of fiscal 2024, we agreed to divest a financially immaterial subsidiary in South America and a line of business in Australia. We did not divest any businesses in fiscal 2023.

Competition

The market for our services is generally competitive. We often compete with many other firms ranging from small regional firms to large international firms.

We perform a broad spectrum of consulting, engineering and technical services across the water, environment, sustainable infrastructure, renewable energy and international development markets. Our competition varies and is a function of the business areas in which, and the client sectors for which, we perform our services. The number of competitors for any procurement can vary widely, depending upon technical qualifications, the relative value of the project, geographic location, the financial terms and risks associated with the work and any restrictions placed upon competition by the client. Historically, clients have chosen among competing firms by weighing the quality, innovation and timeliness of the firm's service versus its cost to determine which firm offers the best value.

Our competitors vary depending on end markets and clients, and often we may only compete with a portion of a firm. We believe that our principal competitors include the following firms, in alphabetical order: AECOM; Arcadis NV; AtkinsRéalis; Black & Veatch Corporation; Booz Allen Hamilton; Brown & Caldwell; CDM Smith Inc.; Chemonics International, Inc.; Exponent, Inc.; GHD; ICF International, Inc.; Jacobs Solutions, Inc.; Leidos, Inc.; SAIC; Stantec Inc.; TRC Companies, Inc.; Weston Solutions, Inc.; and WSP Global Inc.

Backlog

We include in our backlog only those contracts for which funding has been provided and work authorization has been received. We estimate that approximately 70% of our backlog at the end of fiscal 2024 will be recognized as revenue in fiscal 2025, as work is being performed. However, we cannot guarantee that the revenue projected in our backlog will be realized or, if realized, will result in profits. In addition, project cancellations or scope adjustments may occur with respect to contracts reflected in our backlog. For example, certain of our contracts with the U.S. federal government and other clients are terminable at the discretion of the client, with or without cause. These types of backlog reductions could adversely affect our revenue and margins. Accordingly, our backlog as of any particular date is an uncertain indicator of our future earnings.

Our backlog at fiscal 2024 year-end was $5.4 billion, an increase of $586 million, or 12.2%, compared to fiscal 2023 year-end. Of this amount, GSG and CIG reported $3.2 billion and $2.2 billion of backlog, respectively, at fiscal 2024 year-end.

Regulations

We engage in various service activities that are subject to government oversight, including environmental laws and regulations, general government procurement laws and regulations and other regulations and requirements imposed by the specific government agencies with which we conduct business.

Environmental. A significant portion of our business involves the planning, design and program management of pollution control facilities, as well as the assessment and management of remediation activities at hazardous waste sites, U.S. Superfund sites and military bases. In addition, we contract with U.S. federal government entities to destroy hazardous materials. These activities require us to manage, handle, remove, treat, transport and dispose of toxic or hazardous substances.

Some environmental laws, such as the U.S. Superfund law and similar state, provincial and local statutes, can impose liability for the entire cost of clean-up for contaminated facilities or sites upon present and former owners and operators, as well as generators, transporters and persons arranging for the treatment or disposal of such substances. In addition, while we strive to handle hazardous and toxic substances with care and in accordance with safe methods, the possibility of accidents, leaks, spills and events of force majeure always exist. Humans exposed to these materials, including workers or subcontractors engaged in the transportation and disposal of hazardous materials and persons in affected areas, may be injured or become ill. This could result in lawsuits that expose us to liability and substantial damage awards. Liabilities for contamination or human exposure to hazardous or toxic materials, or a failure to comply with applicable regulations, could result in substantial costs, including clean-up costs, fines, civil or criminal sanctions, third party claims for property damage or personal injury or the cessation of remediation activities.

Certain of our business operations are covered by U.S. Public Law 85-804, which provides for government indemnification against claims and damages arising out of unusually hazardous activities performed at the request of the government. Due to changes in public policies and law, however, government indemnification may not be available in the case of any future claims or liabilities relating to other hazardous activities that we perform.

Government Procurement. The services we provide to the U.S. federal government are subject to the FAR and other rules and regulations applicable to government contracts. These rules and regulations:

11

•require certification and disclosure of all cost and pricing data in connection with the contract negotiations under certain contract types;

•impose accounting rules that define allowable and unallowable costs and otherwise govern our right to reimbursement under certain cost-based government contracts; and

•restrict the use and dissemination of information classified for national security purposes and the exportation of certain products and technical data.

In addition, services provided to the DoD and U.S. federal civil agencies are monitored by the Defense Contract Management Agency and audited by the DCAA. Our government clients can also terminate any of their contracts, and many of our government contracts are subject to renewal or extension annually. Further, the services we provide to state and local government clients are subject to various government rules and regulations.

Seasonality

We experience seasonal trends in our business. Our revenue and operating income are typically lower in the first half of our fiscal year, primarily due to the Thanksgiving (in the U.S. and Canada), Christmas and New Year's holidays. Many of our clients' employees, as well as our own employees, take vacations during these holiday periods. Further, seasonal inclement weather conditions occasionally cause some of our offices to close temporarily or may hamper our project field work in the northern hemisphere's temperate and arctic regions. These occurrences result in fewer billable hours worked on projects and, correspondingly, less revenue recognized.

Climate Risk Assessment

We assess the impact of climate risk and opportunity on our operations and business periodically, with the oversight of our Board of Directors. Climate risk is a consideration in business continuity planning and security in regions that may experience climate-related disruptions due to extreme weather, fires, or flooding. Climate related impacts may also create increased demand for our services for response and longer-term recovery needs. In some cases, we may be working in regions that also experience socio-political impacts and security disruptions due to the impacts of extreme weather or prolonged drought conditions. As a professional services company, our workforce is highly mobile, able to work remotely, and can in most cases quickly adapt to changes in local conditions. We have business continuity planning and processes in place to address any acute impact to locally affected operations and have the ability to rapidly move to remote and flexible working arrangements while restoring or relocating affected operations. We maintain a strong information technology infrastructure to facilitate remote working and provide virtual access to systems. Our enterprise and project data is accessible through cloud-based systems, reducing the risk of localized disruptions of data access and computer systems. Our offices are typically leased, so we are not at significant risk of physical building assets being impacted. Selecting project activities can be impacted by climate related events; however, these are addressed through our extensive project risk management process. Climate-related disruptions do, in many cases, result in increased opportunity for project work for Tetra Tech. We provide post-disaster response services and may have additional demand for our expertise if there is an increase in the frequency of climate related events. We are able to mobilize rapidly to deploy additional staff and resources to affected areas. Furthermore, our business includes providing a wide range of water, environment and sustainable infrastructure services, many of which are increasingly in demand to address the longer-term impacts associated with drought, water scarcity, heat, flooding and fire risk.

Risk Management and Insurance

Our business activities could expose us to potential risk and liability under various laws and under workplace health and safety regulations. In addition, we occasionally assume liability by contract under indemnification agreements. We cannot predict the magnitude of such potential liabilities. Our Office of Risk Management reviews and oversees the risk profile of our operations, and reports to our Board of Directors.

We maintain a comprehensive general liability insurance policy with an umbrella policy that covers losses beyond the general liability limits. We also maintain professional errors and omissions liability, contractor's pollution liability, and cyber liability insurance policies. We believe that these policies provide adequate coverage for our business. When we perform higher-risk work, we obtain, if available, the necessary types of insurance coverage for such activities, as is typically required by our clients.

We obtain insurance coverage through a broker that is experienced in our industry. The broker and our risk manager regularly review the adequacy of our insurance coverage. Because there are various exclusions and retentions under our policies, or an insurance carrier may become insolvent, there can be no assurance that all potential liabilities will be covered by our insurance policies or paid by our carrier.

We evaluate the risk associated with insurance claims. If we determine that a loss is probable and reasonably estimable, we establish an appropriate reserve. A reserve is not established if we determine that a claim has no merit or is not probable or reasonably estimable. Our historic levels of insurance coverage and reserves have been adequate. However,

12

partially or completely uninsured claims, if successful and of significant magnitude, could have a material adverse effect on our business.

Human Capital Management

Employees. At fiscal 2024 year-end, we had approximately 30,000 staff worldwide. A large percentage of our employees have technical and professional backgrounds and undergraduate and/or advanced degrees, including the employees of recently acquired companies. Our professional staff includes, but is not limited to, analysts, archaeologists, architects, biologists, chemical engineers, chemists, civil engineers, data scientists, computer scientists, digital engineers, economists, electrical engineers, environmental engineers, environmental scientists, geologists, hydrogeologists, mechanical engineers, software engineers, statisticians, oceanographers, project managers and toxicologists. We consider the current relationships with our employees to be favorable. We are not aware of any employment circumstances that are likely to disrupt work at any of our facilities. See Part I, Item 1A, "Risk Factors" for a discussion of the risks related to the loss of key personnel or our inability to attract and retain qualified personnel.

Health and Safety. Tetra Tech is committed to providing and maintaining a healthy and safe work environment for our associates. We provide training to all associates to support the safe execution of their work to improve their understanding of behaviors that can be perceived as discriminatory, exclusionary and/or harassing, and provide safe avenues for associates to report such behaviors.

Ethics and Compliance. Tetra Tech maintains an unwavering commitment to integrity, ethical practices, and conducting business in full compliance with the law. Our Code of Business Ethics and Conduct outlines the general ethical principles that help us make the right decisions when conducting business worldwide. To support our employees, we provide a variety of resources and trainings and offer multiple avenues to raise questions or concerns - to help ensure long-term success for our employees, company, clients, and shareholders.

Diversity, Equity, Inclusion and Accessibility. Tetra Tech brings together engineers and technical specialists from all backgrounds to solve our clients' most challenging problems. Our Diversity, Equity, Inclusion and Accessibility ("DEIA") Policy guides the Board of Directors, management, associates, subcontractors and partners in developing an inclusive culture. Our DEIA Council monitors Tetra Tech's diversity, equity, inclusion and accessibility practices and makes recommendations to the Board of Directors and Chief Executive Officer for any changes or improvements to our program.

Tetra Tech values diversity, equity, inclusion and accessibility and undertakes various efforts throughout its operations to promote these initiatives. Our current efforts are focused on these primary areas:

•Equal employment opportunity. Tetra Tech ensures that our practices and processes attract a diverse range of candidates and that candidates are recruited, hired, assigned, developed and promoted based on merit and their alignment with our values.

•Enhancing learning and development opportunities. To support our employees in reaching their full potential, Tetra Tech offers a wide range of internal and external learning and development opportunities. Education assistance is offered to financially support associates who seek to expand their knowledge and skill base.

As part of Tetra Tech's commitment to a culture of inclusion, our Employee Resource Group ("ERG") Program broadens and enhances company-wide interaction opportunities for our employees. Tetra Tech's ERGs are open to all associates and involve activities for both employees whose background is the focus of the ERG and those who are supportive of the group (also known as allies). These global networks build on and coordinate with the many local networks that are already active throughout our operations and include groups focused on the experiences of Black, Latino, Pan-Asian, Women, Veterans, Disabled and LGBTQIA+ employees and emerging professionals.

Professional Development. Tetra Tech provides access for all employees to training, technical exchange and collaboration, and skill development resources through its customized Learning Management System, providing professional development opportunities throughout our employees' careers. Technology skills development includes access to a series of live webcasts and recorded technology transfer sessions. Company-wide networking events provide interactive skills development activities. Employees are also provided with access to training in leadership development, project management skills, and interpersonal skills development. Various personal development and wellness programs are sponsored by our Human Resources team. Our Corporate Information Technology team provides access to software training and skills development modules to all employees. Tetra Tech also supports our employees in discipline specific training, certifications, and accreditation programs across the Company. Programs such as specific health and safety programs, hazardous waste investigation, environmental certifications, and professional certifications are encouraged as per client, project and professional development needs.

Item 1A. Risk Factors

We operate in a changing environment that involves numerous known and unknown risks and uncertainties that could materially adversely affect our operations. Set forth below and elsewhere in this report and in other documents we file with the SEC are descriptions of the risks and uncertainties that could cause our actual results to differ materially from the results contemplated by the forward-looking statements contained in this report. Additional risks we do not yet know of or that we currently think are immaterial may also affect our business operations. If any of the events or circumstances described in the following risks actually occurs, our business, financial condition or results of operations could be materially adversely affected.

Risks Related to Our Business and Operations

If we fail to complete a project in a timely manner, miss a required performance standard or otherwise fail to adequately perform on a project, then we may incur a loss on that project, which may reduce or eliminate our overall profitability.

Our engagements often involve large-scale, complex projects. The quality of our performance on such projects depends in large part upon our ability to manage the relationship with our clients and our ability to effectively manage the project and deploy appropriate resources, including third-party contractors and our own personnel, in a timely manner. We may commit to a client that we will complete a project by a scheduled date. We may also commit that a project, when completed, will achieve specified performance standards. If the project is not completed by the scheduled date or fails to meet required performance standards, we may either incur significant additional costs or be held responsible for the costs incurred by the client to rectify damages due to late completion or failure to achieve the required performance standards. The uncertainty of the timing of a project can present difficulties in planning the amount of personnel needed for the project. If the project is delayed or canceled, we may bear the cost of an underutilized workforce that was dedicated to fulfilling the project. In addition, performance of projects can be affected by a number of factors beyond our control, including unavoidable delays from government inaction, public opposition, inability to obtain financing, weather conditions, unavailability of materials, changes in the project scope of services requested by our clients, industrial accidents, environmental hazards and labor disruptions. To the extent these events occur, the total costs of the project could exceed our estimates, and we could experience reduced profits or, in some cases, incur a loss on a project, which may reduce or eliminate our overall profitability. Further, any defects or errors, or failures to meet our clients’ expectations, could result in claims for damages against us. Failure to meet performance standards or complete performance on a timely basis could also adversely affect our reputation and client base.

Demand for our services is cyclical and vulnerable to economic downturns. If economic growth slows, government fiscal conditions worsen or client spending declines, then our revenue, profits and financial condition may deteriorate.

Demand for our services is cyclical, and vulnerable to economic downturns and reductions in government and private industry spending. Such downturns or reductions may result in clients delaying, curtailing or canceling proposed and existing projects. Our business traditionally lags the overall recovery in the economy; therefore, our business may not recover immediately when the economy improves. If economic growth slows, government fiscal conditions worsen or client spending declines, then our revenue, profits and overall financial condition may deteriorate. Our government clients may face budget deficits that prohibit them from funding new or existing projects. In addition, our existing and potential clients may either postpone entering into new contracts or request price concessions. Difficult financing and economic conditions may cause some of our clients to demand better pricing terms or delay payments for services we perform, thereby increasing the average number of days our receivables are outstanding and the potential of increased credit losses of uncollectible invoices. Further, these conditions may result in the inability of some of our clients to pay us for services that we have already performed. If we are not able to reduce our costs quickly enough to respond to the revenue decline from these clients, our operating results may be adversely affected. Accordingly, these factors affect our ability to forecast our future revenue and earnings from business areas that may be adversely impacted by market conditions. Any of these factors could adversely affect the demand for our services, which could have a material adverse effect on our business, results of operations and financial condition.

Our industry is highly competitive, and we may be unable to compete effectively, which could result in reduced revenue, profitability and market share.

16

We are engaged in a highly competitive business. The markets that we serve are highly fragmented and we compete with many regional, national and international companies. Certain of these competitors have greater financial and other resources than we do. Others are smaller and more specialized and concentrate their resources in particular areas of expertise. The extent of our competition varies according to certain markets and geographic area. In addition, the technical and professional aspects of some of our services generally do not require large upfront capital expenditures and provide limited barriers against new competitors.

The degree and type of competition that we face is also influenced by the type and scope of a particular project. Our clients make competitive determinations based upon qualifications, experience, performance, reputation, technology, customer relationships and ability to provide the relevant services in a timely, safe and cost-efficient manner. This competitive environment could force us to make price concessions or otherwise reduce prices for our services. If we are unable to maintain our competitiveness and win bids for future projects, our market share, revenue and profits will decline.

Our international operations 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.

In fiscal 2024, we generated 38.5% of our revenue from our international operations, primarily in Canada, Australia, Europe, the United Kingdom and from international clients for work that is performed by our domestic operations. International business is subject to a variety of risks, including: imposition of governmental controls and changes in laws, regulations or policies; lack of developed legal systems to enforce contractual rights; greater risk of uncollectible accounts and longer collection cycles; currency exchange rate fluctuations, devaluations and other conversion restrictions; uncertain and changing tax rules, regulations and rates; the potential for civil unrest, acts of terrorism, force majeure, war or other armed conflict and greater physical security risks, which may cause us to have to leave a country quickly; logistical and communication challenges; changes in regulatory practices, including trade policies, tariffs and taxes; changes in labor conditions; general economic, political and financial conditions in foreign markets; and exposure to civil or criminal liability under the U.S. Foreign Corrupt Practices Act (“FCPA”), the U.K. Bribery Act, the Canadian Corruption of Foreign Public Officials Act, the Brazilian Clean Companies Act, the anti-boycott rules, trade and export control regulations as well as other international regulations.

International risks and violations of international regulations may significantly reduce our revenue and profits, and subject us to criminal or civil enforcement actions, including fines, suspensions or disqualification from future U.S. federal procurement contracting. Although we have policies and procedures to monitor legal and regulatory compliance, our employees, subcontractors and agents could take actions that violate these requirements. As a result, our international risk exposure may be more or less than the percentage of revenue attributed to our international operations.

Continuing worldwide political, social and economic uncertainties may adversely affect our revenue and profitability.

The last several years have been periodically marked by political, social and economic concerns, including decreased consumer confidence, the lingering effects of international conflicts, and higher energy costs and inflation. Ongoing instability and current conflicts in global markets, including Eastern Europe, the Middle East and Asia, and the potential for other conflicts and future terrorist activities and other recent geopolitical events throughout the world, including the ongoing state of war between Israel and Hamas and the related larger regional conflict, have created and may continue to create economic and political uncertainties and impacts. This instability can make it extremely difficult for our clients, our vendors and us to accurately forecast and plan future business activities, and could cause constrained spending on our services, delays and a lengthening of our business development efforts, the demand for more favorable pricing or other terms and/or difficulty in collection of our accounts receivable. Our government clients may face budget deficits that prohibit them from funding proposed and existing projects. Further, ongoing economic instability in the global markets could limit our ability to access the capital markets at a time when we would like, or need, to raise capital, which could have an impact on our ability to react to changing business conditions or new opportunities. If economic conditions remain uncertain or weakened, or government spending is reduced, our revenue and profitability could be adversely affected.

Our backlog is subject to cancellation, unexpected adjustments and changing economic conditions and is an uncertain indicator of future operating results.

Our backlog at fiscal 2024 year-end was $5.4 billion, an increase of $586 million, or 12.2%, compared to fiscal 2023 year-end. We include in backlog only those contracts for which funding has been provided and work authorizations have been received. We cannot guarantee that the revenue projected in our backlog will be realized or, if realized, will result in profits. In addition, project delays, suspensions, terminations, cancellations, reductions in scope, or other adjustments do occur from time to time in our industry due to considerations beyond our control and may have a material impact on the value of reported backlog with a corresponding adverse impact on future revenues and profitability. For example, certain of our contracts with the U.S. federal government and other clients are terminable at the discretion of the client, with or without cause. These types of backlog reductions could adversely affect our revenue and margins. As a result of these factors, our backlog as of any particular date is an uncertain indicator of our future earnings.

17

The loss of key personnel or our inability to attract and retain qualified personnel could impair our ability to provide services to our clients and otherwise conduct our business effectively.

As primarily a professional and technical services company, we are labor-intensive and, therefore, our ability to attract, retain and expand our senior management and our professional and technical staff is an important factor in determining our future success. The market for qualified scientists and engineers is competitive and, from time to time, it may be difficult to attract and retain qualified individuals with the required expertise within the timeframe demanded by our clients. For example, some of our U.S. government contracts may require us to employ only individuals who have particular government security clearance levels. In addition, if we are unable to retain executives and other key personnel, the roles and responsibilities of those employees will need to be filled, which may require that we devote time and resources to identify, hire and integrate new employees. The loss of the services of any of these key personnel could adversely affect our business. Our failure to attract and retain key individuals could impair our ability to provide services to our clients and conduct our business effectively.

If our contractors and subcontractors fail to satisfy their obligations to us or other parties, or if we are unable to maintain these relationships, our revenue, profitability and growth prospects could be adversely affected.

We depend on contractors and subcontractors in conducting our business. There is a risk that we may have disputes with our subcontractors arising from, among other things, the quality and timeliness of work performed by the subcontractor, client concerns about the subcontractor or our failure to extend existing task orders or issue new task orders under a subcontract. In addition, if a subcontractor fails to deliver on a timely basis the agreed-upon supplies, fails to perform the agreed-upon services or goes out of business, then we may be required to purchase the services or supplies from another source at a higher price, and our ability to fulfill our obligations as a prime contractor may be jeopardized. This may reduce the profit to be realized or result in a loss on a project for which the services or supplies are needed.

We also rely on relationships with other contractors when we act as their subcontractor or joint venture partner. The absence of qualified subcontractors with which we have a satisfactory relationship could adversely affect the quality of our service and our ability to perform under some of our contracts. Our future revenue and growth prospects could be adversely affected if other contractors eliminate or reduce their subcontracts or teaming arrangement relationships with us, or if a government agency terminates or reduces these other contractors’ programs, does not award them new contracts, or refuses to pay under a contract.

Our failure to meet contractual schedule or performance requirements that we have guaranteed could adversely affect our operating results.

In certain circumstances, we can incur liquidated or other damages if we do not achieve project completion by a scheduled date. If we or an entity for which we have provided a guarantee subsequently fails to complete the project as scheduled and the matter cannot be satisfactorily resolved with the client, we may be responsible for cost impacts to the client resulting from any delay or the cost to complete the project. Our costs generally increase from schedule delays and/or could exceed our projections and the anticipated revenue for a particular project. In addition, 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. As a result, material performance problems for existing and future contracts could cause actual results of operations to differ from those anticipated by us and could cause us to suffer damage to our reputation within our industry and client base.

Our failure to implement and comply with our safety program could adversely affect our operating results or financial condition.

Our project sites often put our employees and others in close proximity with mechanized equipment, moving vehicles, chemical and manufacturing processes and highly regulated materials. We maintain an enterprise-wide group of health and safety professionals to help ensure that the services we provide are delivered safely and in accordance with standard work processes. Unsafe job sites and office environments have the potential to increase employee turnover, increase the cost of a project to our clients, expose us to types and levels of risk that are fundamentally unacceptable and raise our operating costs. The implementation of our safety processes and procedures are monitored by various agencies, including the U.S. Mine Safety and Health Administration (“MSHA”), and rating bureaus and may be evaluated by certain clients in cases in which safety requirements have been established in our contracts. Our failure to meet these requirements or our failure to properly implement and comply with our safety program could result in reduced profitability, the loss of projects or clients or potential litigation, and could have a material adverse effect on our business, operating results or financial condition.

Our business activities may require our employees to travel to and work in countries where there are high security risks, which may result in employee death or injury, repatriation costs or other unforeseen costs.

Certain of our contracts require our employees travel to and work in high-risk countries that are undergoing political, social and economic upheavals resulting from war, civil unrest, criminal activity, acts of terrorism or public health crises. As a

18

result, we risk loss of or injury to our employees and may be subject to costs related to employee death or injury, repatriation or other unforeseen circumstances. We may choose or be forced to leave a country with little or no warning due to physical security risks.

Unavailability or cancellation of third-party insurance coverage would increase our overall risk exposure as well as disrupt the management of our business operations.

Our services involve significant risks of professional and other liabilities, which may substantially exceed the fees that we derive from our services. 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. From time to time, we assume liabilities as a result of indemnification provisions contained in our service contracts. We cannot predict the magnitude of these potential liabilities.

We are liable to pay such liabilities from our assets if and when the aggregate settlement or judgment amount exceeds our insurance policy limits. Further, our insurance may not protect us against liability because our policies typically have various exceptions to the claims covered and also require us to assume some costs of the claim even though a portion of the claim may be covered. A partially or completely uninsured claim, if successful and of significant magnitude, could have a material adverse effect on our liquidity.

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, if we expand into new markets, we may not be able to obtain insurance coverage for these new activities or, if insurance is obtained, the dollar amount of any liabilities incurred could exceed our insurance coverage. 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.

Our inability to obtain adequate bonding could have a material adverse effect on our future revenue and business prospects.

Certain clients require bid bonds, and performance and payment bonds. These bonds indemnify the client should we fail to perform our obligations under a contract. If a bond is required for a certain project and we are unable to obtain an appropriate bond, we cannot pursue that project. In some instances, we are required to co-venture with a small or disadvantaged business to pursue certain government contracts. In connection with these ventures, we are sometimes required to utilize our bonding capacity to cover all of the obligations under the contract with the client. We have a bonding facility but, as is typically the case, the issuance of bonds under that facility is at the surety’s sole discretion. There can be no assurance that bonds will continue to be available to us on reasonable terms. Additionally, even if we continue to access bonding capacity to sufficiently bond future work, we may be required to post collateral to secure bonds, which would decrease the liquidity available for other purposes. Our inability to obtain adequate bonding and, as a result, to bid on new work could have a material adverse effect on our future revenue and business prospects.

We may be precluded from providing certain services due to conflict of interest issues.

Many of our clients are concerned about potential or actual conflicts of interest in retaining management consultants. Many commercial and government clients have formal policies against continuing or awarding contracts that would create actual or potential conflicts of interest with other activities of a contractor. These policies may prevent us from bidding for or performing contracts resulting from or relating to certain work we have performed. We have, on occasion, declined to bid on projects due to conflict of interest issues. If we fail to address actual or potential conflicts properly, or even if we simply fail to recognize a perceived conflict, we may be in violation of our existing contracts, may otherwise incur liability, and may lose future business for not preventing the conflict from arising, and our reputation may suffer.

Our actual business and financial results could differ from the estimates and assumptions that we use to prepare our consolidated financial statements, which may significantly reduce or eliminate our profits.

To prepare consolidated financial statements in conformity with generally accepted accounting principles in the U.S., management is required to make estimates and assumptions as of the date of the consolidated financial statements. These estimates and assumptions affect the reported values of assets, liabilities, revenue and expenses as well as disclosures of contingent assets and liabilities. For example, we typically recognize revenue over the life of a contract based on the proportion of costs incurred to date compared to the total costs estimated to be incurred for the entire project. Areas requiring significant estimates by our management include: the application of the percentage-of-completion method of accounting and revenue recognition on contracts, change orders and contract claims, including related unbilled accounts receivable; unbilled accounts receivable, including amounts related to requests for equitable adjustment to contracts that provide for price redetermination, primarily with the U.S. federal government. These amounts are recorded only when they can be reliably estimated and realization is probable; provisions for uncollectible receivables, client claims and recoveries of costs from subcontractors,

19

vendors and others; provisions for income taxes, research and development tax credits, valuation allowances and unrecognized tax benefits; and value of goodwill and recoverability of intangible assets.

Our actual business and financial results could differ from those estimates, which may significantly reduce or eliminate our profits.

Our profitability could suffer if we are not able to maintain adequate utilization of our workforce.

The cost of providing our services, including the extent to which we utilize our workforce, affects our profitability. The rate at which we utilize our workforce is affected by a number of factors, including: our ability to transition employees from completed projects to new assignments and to hire and assimilate new employees; our ability to forecast demand for our services and thereby maintain an appropriate headcount in each of our geographies and operating units; and our ability to manage attrition.

If we over-utilize our workforce, our employees may become disengaged, which could impact employee attrition. If we under-utilize our workforce, our profit margin and profitability could suffer.

Our use of the percentage-of-completion method of revenue recognition could result in a reduction or reversal of previously recorded revenue and profits.

We account for most of our contracts on the percentage-of-completion method of revenue recognition. Generally, our use of this method results in recognition of revenue and profit ratably over the life of the contract, based on the proportion of costs incurred to date to total costs expected to be incurred for the entire project. The effects of revisions to estimated revenue and costs, including the achievement of award fees and the impact of change orders and claims, are recorded when the amounts are known and can be reasonably estimated. Such revisions could occur in any period and their effects could be material. Although we have historically made reasonably reliable estimates of the progress towards completion of long-term contracts, the uncertainties inherent in the estimating process make it possible for actual costs to vary materially from estimates, including reductions or reversals of previously recorded revenue and profit.

If we are unable to accurately estimate and control our contract costs, then we may incur losses on our contracts, which could decrease our operating margins and reduce our profits. Specifically, our fixed-price contracts could increase the unpredictability of our earnings.

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

The U.S. federal government and certain other clients have increased the use of fixed-priced contracts. Under fixed-price contracts, we receive a fixed price irrespective of the actual costs we incur and, consequently, we are exposed to a number of risks. We realize a profit on fixed-price contracts only if we can control our costs and prevent cost over-runs on our contracts. Fixed-price contracts require cost and scheduling estimates that are based on a number of assumptions, including those about future economic conditions, costs and availability of labor, equipment and materials and other exigencies. We could experience cost over-runs if these estimates are originally inaccurate as a result of errors or ambiguities in the contract specifications or become inaccurate as a result of a change in circumstances following the submission of the estimate due to, among other things, unanticipated technical or equipment problems, difficulties in obtaining permits or approvals, changes in local laws or labor conditions, weather delays, changes in the costs of raw materials or the inability of our vendors or subcontractors to perform their obligations. If cost overruns occur, we could experience reduced profits or, in some cases, a loss for that project and could increase the unpredictability of our earnings, as well as have a material adverse impact on our business and earnings.

Under our time-and-materials contracts, we are paid for labor at negotiated hourly billing rates and paid for other expenses. Profitability on these contracts is driven by billable headcount and cost control. Many of our time-and-materials contracts are subject to maximum contract values and, accordingly, revenue relating to these contracts is recognized as if these contracts were fixed-price contracts. Under our cost-plus contracts, some of which are subject to contract ceiling amounts, we are reimbursed for allowable costs and fees, which may be fixed or performance-based. If our costs exceed the contract ceiling or are not allowable under the provisions of the contract or any applicable regulations, we may not be able to obtain reimbursement for all of the costs we incur.

Profitability on our contracts is driven by billable headcount and our ability to manage our subcontractors, vendors and material suppliers. If we are unable to accurately estimate and manage our costs, we may incur losses on our contracts, which could decrease our operating margins and significantly reduce or eliminate our profits. Certain of our contracts require us to satisfy specific design, engineering, procurement or construction milestones in order to receive payment for the work completed or equipment or supplies procured prior to achievement of the applicable milestone. As a result, under these types of arrangements, we may incur significant costs or perform significant amounts of services prior to receipt of payment. If a client

20

determines not to proceed with the completion of the project or if the client defaults on its payment obligations, we may face difficulties in collecting payment of amounts due to us for the costs previously incurred or for the amounts previously expended to purchase equipment or supplies.

Accounting for a contract requires judgments relative to assessing the contract’s estimated risks, revenue, costs and other technical issues. Due to the size and nature of many of our contracts, the estimation of overall risk, revenue and cost at completion is complicated and subject to many variables. Changes in underlying assumptions, circumstances or estimates may also adversely affect future period financial performance. If we are unable to accurately estimate the overall revenue or costs on a contract, then we may experience a lower profit or incur a loss on the contract.

Cyber security incidents affecting our systems and information technology could adversely impact our ability to operate and we could experience adverse consequences resulting from such compromises, including but not limited to regulatory investigations or actions; litigation; fines and penalties; disruptions of our business operations; reputational harm; loss of revenue or profits; and other adverse consequences.

We face the threat to our computer systems of unauthorized access, computer hackers, computer viruses, malicious code, organized cyber-attacks and other security problems and system disruptions, including possible unauthorized access to our and our clients' proprietary or classified information. We rely on industry-accepted security measures and technology to securely maintain all confidential and proprietary information on our information systems. In addition, we rely on the security of third-party service providers, vendors and cloud services providers to protect confidential data. In the ordinary course of business, we have been targeted by malicious cyber-attacks. A user who circumvents security measures could misappropriate confidential or proprietary information, including information regarding us, our personnel and/or our clients or cause interruptions or malfunctions in operations. As a result, we may be required to expend significant resources to protect against the threat of these system disruptions and security breaches or to alleviate problems caused by these disruptions and breaches.

We also rely in part on third-party software and information technology vendors to run our critical accounting, project management and financial information systems. Our software and information technology vendors may decide to discontinue further development, integration or long-term software and hardware support for our information systems, in which case we may need to abandon one or more of our current information systems and migrate some or all of our accounting, project management and financial information to other systems, thus increasing our operational expense, as well as disrupting the management of our business operations.

While we have implemented security measures designed to protect against security incidents, there can be no assurance that these measures will be effective. Vulnerabilities in our systems pose material risks to our business. Applicable data privacy and security obligations may require us to notify relevant stakeholders of security incidents. Such disclosures are costly, and the disclosure or the failure to comply with such requirements could lead to adverse consequences. Any of these events could damage our reputation and have a material adverse effect on our business, financial condition, results of operations and cash flows.

In addition, we cannot be sure that our insurance coverage will be adequate or sufficient to protect us from or to mitigate liabilities arising out of our privacy and security practices, that such coverage will continue to be available on commercially reasonable terms or at all, or that such coverage will pay future claims.

Risks Related to Our Clients

We derive a substantial amount of our revenue from U.S. federal, state and local government agencies, and any disruption in government funding or in our relationship with those agencies could adversely affect our business.

In fiscal 2024, we generated 44.0% of our revenue from contracts with U.S. federal, and state and local government agencies. A significant amount of this revenue is derived under multi-year contracts, many of which are appropriated on an annual basis. As a result, at the beginning of a project, the related contract may be only partially funded, and additional funding is normally committed only as appropriations are made in each subsequent year. These appropriations, and the timing of payment of appropriated amounts, may be influenced by numerous factors as noted below. Our backlog includes only the projects that have funding appropriated.

The demand for our U.S. government-related services is generally driven by the level of government program funding. A significant reduction in federal government spending, the absence of a bipartisan agreement on the federal government budget, a partial or full federal government shutdown or a change in budgetary priorities could reduce demand for our services, cancel or delay federal projects, result in the closure of federal facilities and significant personnel reductions and have a material and adverse impact on our business, financial condition, results of operations and cash flows.

There are several additional factors that could materially affect our U.S. government contracting business, which could cause U.S. government agencies to delay or cancel programs, to reduce their orders under existing contracts, to exercise their rights to terminate contracts or not to exercise contract options for renewals or extensions. Such factors, which include the

21

following, could have a material adverse effect on our revenue or the timing of contract payments from U.S. government agencies: the failure of the U.S. government to complete its budget and appropriations process before its fiscal year-end; changes in and delays or cancellations of government programs, procurements, requirements or appropriations; budget constraints or policy changes resulting in delay or curtailment of expenditures related to the services we provide; and re-competes of government contracts.

Our failure to win new contracts and renew existing contracts with private and public sector clients could adversely affect our profitability.

Our business depends on our ability to win new contracts and renew existing contracts with private and public sector clients. Contract proposals and negotiations are complex and frequently involve a lengthy bidding and selection process, which is affected by a number of factors. These factors include market conditions, financing arrangements, required governmental approvals, client relationships and our professional reputation. If we are not able to replace the revenue from expiring contracts, either through follow-on contracts or new contracts, our business, results of operations and financial condition may be adversely affected. If negative market conditions continue to persist, or if we fail to secure adequate financial arrangements or the required government approval, we may not be able to pursue certain projects, which could adversely affect our profitability.

Our inability to win or renew U.S. government contracts during regulated procurement processes could harm our operations and significantly reduce or eliminate our profits.

U.S. government contracts are awarded through a regulated procurement process. The U.S. federal government has increasingly relied upon multi-year contracts with pre-established terms and conditions, such as indefinite delivery/indefinite quantity (“IDIQ”) contracts, which generally require those contractors who have previously been awarded the IDIQ to engage in an additional competitive bidding process before a task order is issued. As a result, new work awards tend to be smaller and of shorter duration, since the orders represent individual tasks rather than large, programmatic assignments. In addition, we believe that there has been an increase in the award of federal contracts based on a low-price, technically acceptable criteria emphasizing price over qualitative factors, such as past performance. As a result, pricing pressure may reduce our profit margins on future federal contracts. Moreover, even if we are qualified to work on a government contract, we may not be awarded the contract because of existing government policies designed to protect small businesses and under-represented minority contractors. Our inability to win or renew government contractsduring regulated procurement processes could harm our operations and significantly reduce or eliminate our profits.

Each year, client funding for some of our U.S. government contracts may rely on government appropriations or public-supported financing. If adequate public funding is delayed or is not available, then our profits and revenue could decline.

A substantial portion of our revenue is derived from contracts with agencies and departments of federal, state and local governments. Each year, client funding for some of our U.S. government contracts may directly or indirectly rely on government appropriations or public-supported financing. Legislatures may appropriate funds for a given project on a year-by-year basis, even though the project may take more than one year to perform. In addition, public-supported financing such as U.S. state and local municipal bonds may be only partially raised to support existing projects. Similarly, an economic downturn may make it more difficult for governments to fund projects. In addition to the state of the economy and competing political priorities, public funds and the timing of payment of these funds may be influenced by, among other things, curtailments in the use of government contracting firms, increases in raw material costs, delays associated with insufficient numbers of government staff to oversee contracts, budget constraints, the timing and amount of tax receipts and the overall level of government expenditures. If adequate funding is not available or is delayed, then our profits and revenue could decline.

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.

We depend on the timely collection of our receivables to generate cash flow, provide working capital, and continue our business operations. If the U.S. government or any other client or any prime contractor for whom we are a subcontractor fails to pay or delays the payment of invoices for any reason, our business and financial condition may be materially and adversely affected. Clients may delay or fail to pay invoices for a number of reasons, including lack of appropriated funds, lack of an approved budget, lack of revised or final settled billing rates as a result of open audit years, as a result of audit findings by government regulatory agencies or for a variety of other reasons.

Certain contracts may give clients the right to modify, delay, curtail, renegotiate or terminate existing contracts at their convenience at any time prior to their completion, which may result in a decline in our profits and revenue.

Certain projects in which we participate as a contractor or subcontractor may extend for several years. Generally, government contracts include the right to modify, delay, curtail, renegotiate or terminate contracts and subcontracts at the government’s convenience any time prior to their completion. Any decision by a client to modify, delay, curtail, renegotiate or terminate our contracts at their convenience may result in a decline in our profits and revenue. If one of these clients terminates

22

their contract for convenience, we may only be able to bill the client for work completed prior to the termination, plus any commitments and settlement expenses such client agrees to pay, but not for any work not yet performed.

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, 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 Indebtedness

Servicing our debt requires a significant amount of cash, and we may not have sufficient cash flow from our business to pay our debt.

Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness, including our convertible notes, depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to service our debt and make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations.

We may not be able to obtain capital when desired on favorable terms, if at all, or without dilution to our stockholders, which may impact our ability to execute on our current or future business strategies.

If we do not generate sufficient cash flow from operations or otherwise, we may need additional financing to execute on our current or future business strategies, including developing new or enhancing existing service lines, expanding our business geographically, enhancing our operating infrastructure, acquiring complementary businesses, or otherwise responding to competitive pressures. We cannot assure that additional financing will be available to us on favorable terms, or at all. Furthermore, if we raise additional funds through the issuance of convertible debt or equity securities, the percentage ownership of our stockholders could be significantly diluted, and these newly issued securities may have rights, preferences or privileges senior to those of existing stockholders. If adequate funds are not available or are not available on acceptable terms, if and when needed, our ability to fund our operations, meet obligations in the normal course of business, take advantage of strategic business opportunities, or otherwise respond to competitive pressures would be significantly limited.

Restrictive covenants in our credit agreement may restrict our ability to pursue certain business strategies.

Our credit agreement limits or restricts our ability to, among other things: incur additional indebtedness; create liens securing debt or other encumbrances on our assets; make loans or advances; pay dividends or make distributions to our stockholders; purchase or redeem our stock; repay indebtedness that is junior to indebtedness under our credit agreement; acquire the assets of, or merge or consolidate with, other companies; and sell, lease or otherwise dispose of assets.

Our credit agreement also requires that we maintain certain financial ratios, which we may not be able to achieve. The covenants may impair our ability to finance future operations or capital needs or to engage in other favorable business activities. Failing to comply with these covenants could result in an event of default under the credit agreement, which could result in us being required to repay the amounts outstanding prior to maturity. These prepayment obligations could have an adverse effect on our business, results of operations and financial condition.

Furthermore, if we are unable to repay the amounts due and payable under the credit agreement, the lenders could proceed against the collateral granted to them to secure that indebtedness. In the event the lenders accelerate the repayment of our borrowings, we and our subsidiaries may not have sufficient assets to repay that indebtedness.

We may not have the ability to raise the funds necessary to settle conversions of our convertible notes or to repurchase our convertible notes upon a fundamental change, and our future debt may contain limitations on our ability to pay cash upon conversion or repurchase of our convertible notes.

Holders of our convertiblenotes have the right, subject to certain conditions and limited exceptions, to require us to repurchase all or a portion of their convertible notes upon the occurrence of a fundamental change (as defined in the indenture governing the convertible notes) at a fundamental change repurchase price equal to 100% of the principal amount of the convertible notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change

23

repurchase date. In addition, upon any conversion of our convertible notes, we will be required to make cash payments for each $1,000 in principal amount of our convertible notes converted of at least the lesser of $1,000 and the sum of the daily conversion values indenture governing our convertible notes. However, we may not have enough available cash or be able to obtain financing at the time we are required to make repurchases of our convertiblenotes surrendered or pay cash with respect to our convertible notes being converted. In addition, our ability to repurchase our convertiblenotes or to pay cash upon conversions of our convertible notes may be limited by law, by regulatory authority or by agreements governing our future indebtedness. Our failure to repurchase our convertiblenotes at a time when the repurchase is required by the indenture governing our convertible notes or to pay any cash payable on future conversions of our convertible notes as required by the indenture governing our convertible notes would constitute a default under the indenture governing our convertible notes. A default under the indenture governing our convertible notes or the fundamental change itself could also lead to a default under agreements governing our indebtedness. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase our convertible notes or make cash payments upon conversions thereof.

The conditional conversion feature of our convertible notes, if triggered, may adversely affect our financial condition and operating results.

In the event the conditional conversion feature of our convertible notes is triggered, holders of our convertible notes will be entitled to convert their notes at any time during specified periods at their option. If one or more holders elect to convert their notes, we would be required to settle any converted principal amount of such notes through the payment of cash, which could adversely affect our liquidity. In addition, even if holders do not elect to convert their notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of our convertible notes as a current rather than long-term liability, which would result in a material reduction of our net working capital.

Changes in the accounting method for convertible debt securities that may be settled in cash, such as our convertible notes, could have a material effect on our reported financial results.

The accounting method for reflecting our convertible notes on our balance sheet, accruing interest expense for our convertible notes and reflecting the underlying shares of our common stock in our reported diluted earnings per share may adversely affect our reported earnings and financial condition.

In August 2020, the Financial Accounting Standards Board published Accounting Standards Update (“ASU”) 2020-06 (“ASU 2020-06”), which simplified certain of the accounting standards that apply to convertible notes. ASU 2020-06 eliminated the cash conversion and beneficial conversion feature modes used to separately account for embedded conversion features as a component of equity. Instead, an entity would account for convertible debt or convertible preferred stock securities as a single unit of account, unless the conversion feature requires bifurcation and recognition as derivatives. Additionally, the guidance requires entities to use the “if-converted” method for all convertible instruments in the diluted earnings per share calculation and to include the effect of potential share settlement for instruments that may be settled in cash or shares. We adopted ASU 2020-06 in the first quarter of fiscal year 2020.

In accordance with ASU 2020-06, our convertible notes are reflected as a liability on our balance sheets, with the initial carrying amount equal to the principal amount of the convertible notes, net of issuance costs. The issuance costs were treated as contra debt for accounting purposes, which will be amortized into interest expense over the term of our convertible notes. As a result of this amortization, the interest expense that we expect to recognize for our convertible notes for accounting purposes will be greater than the cash interest payments we will pay on our convertible notes.

In addition, the shares of our common stock underlying our convertible notes will be reflected in our diluted earnings per share using the “if-converted” method, in accordance with ASU 2020-06. Under the “if-converted” method, diluted earnings per share would generally be calculated assuming that all our convertible notes were converted solely into shares of our common stock at the beginning of the reporting period, unless the result would be anti-dilutive. However, for convertible notes in which the principal amount must be settled in cash and the conversion spread value in shares or cash upon conversions (such as our convertible notes), the “if-converted” method requires that interest expense is not adjusted in the numerator and the denominator only includes the net number of incremental shares that would be issued upon conversion. The application of the if-converted method may reduce our reported diluted earnings per share, to the extent the price of our common stock exceeds the conversion price. Accounting standards may change in the future in a manner that may adversely affect our diluted earnings per share.

Furthermore, if any of the conditions to the convertibility of our convertible notes is satisfied, then we may be required under applicable accounting standards to reclassify the liability carrying value of our convertible notes as a current, rather than a long-term, liability. This reclassification could be required even if no holders convert their notes and could materially reduce our reported working capital.

24

Conversion of our convertible notes may dilute the ownership interest of our stockholders or may otherwise depress the price of our common stock.

The conversion of some or all of our convertible notes may dilute the ownership interests of our stockholders. Upon conversion of our convertible notes, we have the option to pay or deliver, as the case may be, cash, shares of our common stock, or a combination of cash and shares of our common stock in respect of the remainder, if any, of our conversion obligation in excess of the aggregate principal amount of our convertible notes being converted. If we elect to settle the remainder, if any, of our conversion obligation in excess of the aggregate principal amount of our convertible notes being converted in shares of our common stock or a combination of cash and shares of our common stock, any sales in the public market of our common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. In addition, the existence of our convertible notes may encourage short selling by market participants because the conversion of our convertible notes could be used to satisfy short positions, or anticipated conversion of our convertible notes into shares of our common stock could depress the price of our common stock.

The capped call transactions may affect the value of our common stock.

In connection with the pricing of our convertible notes, we entered into privately negotiated capped call transactions with the option counterparties. The capped call transactions cover, subject to customary adjustments substantially similar to those applicable to our convertible notes, the number of shares of our common stock initially underlying our convertible notes. The capped call transactions are expected generally to reduce the potential dilution to our common stock upon any conversion of our convertible notes and/or offset any cash payments we are required to make in excess of the principal amount of converted notes (if and when we elect to settle the conversion spread value in cash), as the case may be, with such reduction and/or offset subject to a cap.

In addition, the option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to our common stock and/or purchasing or selling our common stock or other securities of ours in secondary market transactions following the pricing of our convertible notes and prior to the maturity of our convertible notes (and are likely to do so during any observation period related to a conversion of our convertible notes or, to the extent we exercise the relevant election under the capped call transactions, following any repurchase or redemption of our convertible notes). This activity could also cause or avoid an increase or a decrease in the market price of our common stock.

In addition, if any such capped call transactions fail to become effective, the option counterparties or their respective affiliates may unwind their hedge positions with respect to our common stock, which could adversely affect the value of our common stock.

We are subject to counterparty risk with respect to the capped call transactions.

The option counterparties are financial institutions, and we are subject to the risk that any or all of them might default under the capped call transactions. Our exposure to the credit risk of the option counterparties is not secured by any collateral.

If an option counterparty becomes subject to insolvency proceedings, we will become an unsecured creditor in those proceedings with a claim equal to our exposure at that time under the capped call transaction with such option counterparty. Our exposure will depend on many factors but, generally, an increase in our exposure will be correlated to an increase in the market price and in the volatility of our common stock. In addition, upon a default by an option counterparty, we may suffer adverse tax consequences and more dilution than we currently anticipate with respect to our common stock. We can provide no assurances as to the financial stability or viability of the option counterparties.

Risks Related to Growth and Acquisitions

If we are not able to successfully manage our growth strategy, our business and results of operations may be adversely affected.

Our expected future growth presents numerous managerial, administrative, operational and other challenges. Our ability to manage the growth of our operations will require us to continue to improve our management information systems and our other internal systems and controls. In addition, our growth will increase our need to attract, develop, motivate and retain both our management and professional employees. The inability to effectively manage our growth or the inability of our employees to achieve anticipated performance could have a material adverse effect on our business.

We have made and expect to continue to make acquisitions. Acquisitions could disrupt our operations and adversely impact our business and operating results. Our failure to conduct due diligence effectively or our inability to successfully integrate acquisitions could impede us from realizing all of the benefits of the acquisitions, which could weaken our results of operations.

A key part of our growth strategy is to acquire other companies that complement our lines of business or that broaden our technical capabilities and geographic presence. However, our ability to make acquisitions is restricted under our credit

25

agreement. Acquisitions involve certain known and unknown risks that could cause our actual growth or operating results to differ from our expectations or the expectations of securities analysts. For example: we may not be able to identify suitable acquisition candidates or to acquire additional companies on acceptable terms; we have completed and we will continue to pursue international acquisitions, which inherently pose more risk than domestic acquisitions; we compete with others to acquire companies, which may result in decreased availability of, or increased price for, suitable acquisition candidates; and we may not be able to obtain the necessary financing, on favorable terms or at all, to finance any of our potential acquisitions.

If we fail to conduct due diligence on our potential targets effectively, we may, for example, not identify problems at target companies, or fail to recognize incompatibilities or other obstacles to successful integration. The integration process may disrupt our business and, if implemented ineffectively, may preclude realization of the full benefits expected by us and could harm our results of operations.

Further, acquisitions may cause us to: issue common stock that would dilute our current stockholders’ ownership percentage; use a substantial portion of our cash resources; increase our interest expense, leverage and debt service requirements (if we incur additional debt to fund an acquisition); or record goodwill and non-amortizable intangible assets that are subject to impairment testing and potential impairment charges.

If our goodwill or other intangible assets become impaired, then our profits may be significantly reduced.

Because we have historically acquired a significant number of companies, goodwill and other intangible assets represent a substantial portion of our assets. As of fiscal 2024 year-end, our goodwill was $2.0 billion and other intangible assets were $160.6 million. We are required to perform a goodwill impairment test for potential impairment at least on an annual basis. We also assess the recoverability of the unamortized balance of our intangible assets when indications of impairment are present based on expected future profitability and undiscounted expected cash flows and their contribution to our overall operations. The goodwill impairment test requires us to determine the fair value of our reporting units, which are the components one level below our reportable segments. In determining fair value, we make significant judgments and estimates, including assumptions about our strategic plans with regard to our operations. We also analyze current economic indicators and market valuations to help determine fair value. To the extent economic conditions that would impact the future operations of our reporting units change, our goodwill may be deemed to be impaired, and we would be required to record a non-cash charge that could result in a material adverse effect on our financial position or results of operations. We had no goodwill impairment in fiscal 2024, 2023 or 2022.

Risks Related to Our Legal and Regulatory Environment

As a U.S. government contractor, we must comply with various procurement laws and regulations and are subject to regular government audits; a violation of any of these laws and regulations or the failure to pass a government audit could result in sanctions, contract termination, forfeiture of profit, harm to our reputation or loss of our status as an eligible government contractor and could reduce our profits and revenue.

We must comply with and are affected by U.S. federal, state, local and foreign laws and regulations relating to the formation, administration and performance of government contracts. For example, we must comply with FAR, the Truth in Negotiations Act, CAS, the American Recovery and Reinvestment Act of 2009, the Services Contract Act, the DoD security regulations as well as many other rules and regulations. In addition, we must comply with other government regulations related to employment practices, environmental protection, health and safety, tax, accounting, anti-fraud measures as well as many other regulations in order to maintain our government contractor status. Although we take precautions to prevent and deter fraud, misconduct and non-compliance, we face the risk that our employees or outside partners may engage in misconduct, fraud or other improper activities. U.S. government agencies, such as the DCAA, routinely audit and investigate government contractors. These government agencies review and audit a government contractor’s performance under its contracts and cost structure, and evaluate compliance with applicable laws, regulations and standards. In addition, during the course of its audits, the DCAA may question our incurred project costs. If the DCAA believes we have accounted for such costs in a manner inconsistent with the requirements for FAR or CAS, the DCAA auditor may recommend to our U.S. government corporate administrative contracting officer that such costs be disallowed. Historically, we have not experienced significant disallowed costs as a result of government audits. However, we can provide no assurance that the DCAA or other government audits will not result in material disallowances for incurred costs in the future. In addition, U.S. government contracts are subject to various other requirements relating to the formation, administration, performance and accounting for these contracts. We may also be subject to qui tam litigation brought by private individuals on behalf of the U.S. government under the Federal Civil False Claims Act, which could include claims for treble damages. For example, as discussed elsewhere in this report, on January 14, 2019, the Civil Division of the United States Attorney’s Office ("USAO") filed complaints in intervention in three qui tam actions filed against our subsidiary, Tetra Tech EC, Inc. ("TtEC"), in the U.S. District Court for the Northern District of California ("NDCA"). U.S. government contract violations could result in the imposition of civil and criminal penalties or sanctions, contract termination, forfeiture of profit and/or suspension of payment, any of which could make us lose our status as

26

an eligible government contractor. We could also suffer serious harm to our reputation. Any interruption or termination of our U.S. government contractor status could reduce our profits and revenue significantly.

Legal proceedings, investigations and disputes could result in substantial monetary penalties and damages, especially if such penalties and damages exceed or are excluded from existing insurance coverage.

We engage in consulting, engineering, program management and technical services that can result in substantial injury or damages that may expose us to legal proceedings, investigations and disputes. For example, in the ordinary course of our business, we may be involved in legal disputes regarding personal injury claims, employee or labor disputes, professional liability claims and general commercial disputes involving project cost overruns and liquidated damages as well as other claims. In addition, in the ordinary course of our business, we frequently make professional judgments and recommendations about environmental and engineering conditions of project sites for our clients, and we may be deemed to be responsible for these judgments and recommendations if they are later determined to be inaccurate. For example, as discussed elsewhere in this report, the USAO filed complaints against TtEC in the NDCA alleging violations of the False Claims Act, Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended (“CERCLA”) and common law, and several ancillary claims brought by third-party private plaintiffs arising from the same services provided by TtEC on the same project are ongoing. Any unfavorable legal ruling against us could result in substantial monetary damages or even criminal violations. We maintain insurance coverage as part of our overall legal and risk management strategy to minimize our potential liabilities; however, insurance coverage contains exclusions and other limitations that may not cover our potential liabilities. Generally, our insurance program covers workers’ compensation and employer’s liability, general liability, automobile liability, professional errors and omissions liability, property and contractor’s pollution liability (in addition to other policies for specific projects). Our insurance program includes deductibles or self-insured retentions for each covered claim that may increase over time. In addition, our insurance policies contain exclusions that insurance providers may use to deny or restrict coverage. Excess liability and professional liability insurance policies provide for coverage on a “claims-made” basis, covering only claims actually made and reported during the policy period currently in effect. If we sustain liabilities that exceed or that are excluded from our insurance coverage, or for which we are not insured, it could have a material adverse impact on our financial condition, results of operations and cash flows.

We could be adversely affected by violations of the FCPA and similar worldwide anti-bribery laws.

The FCPA and similar anti-bribery laws generally prohibit companies and their intermediaries from making direct or indirect improper payments to foreign government officials for the purpose of obtaining or retaining business. The FCPA also requires public companies to make and keep books and records that accurately and fairly reflect the transactions of the corporation and to devise and maintain an adequate system of internal accounting controls. The U.K. Bribery Act of 2010 prohibits both domestic and international bribery, as well as bribery across both private and public sectors. Improper payments are also prohibited under the Canadian Corruption of Foreign Public Officials Act and the Brazilian Clean Companies Act. Local business practices in many countries outside the United States create a greater risk of government corruption than that found in the United States and other more developed countries. Our policies mandate compliance with anti-bribery laws, and we have established policies and procedures designed to monitor compliance with anti-bribery law requirements; however, we cannot ensure that our policies and procedures will prevent potential reckless or criminal acts committed by individual employees, agents or partners. If we are found to be liable for anti-bribery law violations, we could suffer from criminal or civil penalties or other sanctions that could have a material adverse effect on our business.

We could be adversely impacted if we fail to comply with domestic and international export control and sanctions laws.

To the extent we export technical services, data and products outside of the United States, we are subject to U.S. and international laws and regulations governing international trade and exports, including but not limited to the International Traffic in Arms Regulations, the Export Administration Regulations and trade sanctions. These laws and regulations may restrict or prohibit altogether the sale or supply of certain of our services to certain governments, persons, entities, countries, and territories, including those that are the target of comprehensive sanctions, unless there are license exceptions that apply or specific licenses are obtained. A failure to comply with these laws and regulations could result in civil or criminal sanctions, including the imposition of fines, the denial of export privileges and suspension or debarment from participation in U.S. government contracts, which could have a material adverse effect on our business.

New legal requirements could adversely affect our operating results.

Our business and results of operations could be adversely affected by the passage of climate change, defense, environmental, infrastructure and other legislation, policies and regulations. Growing concerns about climate change may result in the imposition of additional environmental regulations. For example, legislation, international protocols, regulation or other restrictions on emissions could increase the costs of projects for our clients or, in some cases, prevent a project from going forward, thereby potentially reducing the need for our services. In addition, relaxation or repeal of laws and regulations, or changes in governmental policies regarding environmental, defense, infrastructure or other industries we serve could result in a decline in demand for our services, which could in turn negatively impact our revenues. We cannot predict when or whether any of these various proposals may be enacted or what their effect will be on us or on our customers.

27

We may be subject to liabilities under environmental laws and regulations.

Our services are subject to numerous U.S. and international environmental protection laws and regulations that are complex and stringent. For example, we must comply with a number of U.S. federal government laws that strictly regulate the handling, removal, treatment, transportation and disposal of toxic and hazardous substances. Under CERCLA and comparable state laws, we may be required to investigate and remediate regulated hazardous materials. CERCLA and comparable state laws typically impose strict, joint and several liabilities without regard to whether a company knew of or caused the release of hazardous substances. The liability for the entire cost of clean-up could be imposed upon any responsible party. Other principal U.S. federal environmental, health and safety laws affecting us include, but are not limited to, the Resource Conservation and Recovery Act, National Environmental Policy Act, the Clean Air Act, the Occupational Safety and Health Act, the Federal Mine Safety and Health Act of 1977 (the “Mine Act”), the Toxic Substances Control Act and the Superfund Amendments and Reauthorization Act. Our business operations may also be subject to similar state and international laws relating to environmental protection. Further, past business practices at companies that we have acquired may also expose us to future unknown environmental liabilities. Liabilities related to environmental contamination or human exposure to hazardous substances, or a failure to comply with applicable regulations, could result in substantial costs to us, including clean-up costs, fines, civil or criminal sanctions, and third-party claims for property damage or personal injury or cessation of remediation activities. Our continuing work in the areas governed by these laws and regulations exposes us to the risk of substantial liability.

Uncertainties in the interpretation and application of existing, new and proposed tax laws and regulations could materially affect our tax obligations and effective tax rate.

The tax regimes to which we are subject or under which we operate are unsettled and may be subject to significant change. The issuance of additional guidance related to existing or future tax laws, or changes to tax laws, tax treaties or regulations proposed or implemented by the current or a future U.S. presidential administration, Congress, taxing authorities in other jurisdictions, including jurisdictions outside of the United States, or by bodies such as the European Commission or the Organisation for Economic Co-operation and Development ("OECD"), could materially affect our tax obligations (including the cost of compliance) and effective tax rate. To the extent that such changes have a negative impact on us, including as a result of related uncertainty, these changes may adversely impact our business, financial condition, results of operations, and cash flows.

The amount of taxes we pay in different jurisdictions depends on the application of the tax laws of various jurisdictions, including the United States, to our international business activities, the relative amounts of income before taxes in the various jurisdictions in which we operate, new or revised tax laws, or interpretations of tax laws and policies, the outcome of current and future tax audits, examinations or administrative appeals, our ability to realize our deferred tax assets, and our ability to operate our business in a manner consistent with our corporate structure and intercompany arrangements. The taxing authorities of the jurisdictions in which we operate may challenge our methodologies for pricing intercompany transactions pursuant to our intercompany arrangements or disagree with our determinations as to the income and expenses attributable to specific jurisdictions. If such a challenge or disagreement were to occur, and our position was not sustained, we could be required to pay additional taxes, interest, and penalties, which could result in one-time tax charges, higher effective tax rates, reduced cash flows, and lower overall profitability of our operations. Our financial statements could fail to reflect adequate reserves to cover such a contingency. Similarly, a taxing authority could assert that we are subject to tax in a jurisdiction where we believe we have not established a taxable connection, often referred to as a “permanent establishment” under international tax treaties, and such an assertion, if successful, could increase our expected tax liability in one or more jurisdictions.

Employee, agent or partner misconduct, or our failure to comply with anti-bribery and other laws or regulations, could harm our reputation, reduce our revenue and profits and subject us to criminal and civil enforcement actions.

Misconduct, fraud, non-compliance with applicable laws and regulations or other improper activities by one of our employees, agents or partners could have a significant negative impact on our business and reputation. Such misconduct could include the failure to comply with government procurement regulations, regulations regarding the protection of classified information, regulations prohibiting bribery and other foreign corrupt practices, regulations regarding the pricing of labor and other costs in government contracts, regulations on lobbying or similar activities, regulations pertaining to the internal controls over financial reporting, environmental laws and any other applicable laws or regulations. Our policies mandate compliance with these regulations and laws, and we take precautions to prevent and detect misconduct. However, since our internal controls are subject to inherent limitations, including human error, it is possible that these controls could be intentionally circumvented or become inadequate because of changed conditions. As a result, we cannot assure that our controls will protect us from reckless or criminal acts committed by our employees, agents or partners. Our failure to comply with applicable laws or regulations or acts of misconduct could subject us to fines and penalties, loss of security clearances and suspension or debarment from contracting, any or all of which could harm our reputation, reduce our revenue and profits and subject us to criminal and civil enforcement actions.

If our reports and opinions are not in compliance with professional standards and other regulations, we could be subject to monetary damages and penalties.

28

We issue reports and opinions to clients based on our professional engineering expertise, as well as our other professional credentials. Our reports and opinions may need to comply with professional standards, licensing requirements, securities regulations and other laws and rules governing the performance of professional services in the jurisdiction in which the services are performed. In addition, the reports and other work product we produce for clients sometimes include projections, forecasts and other forward-looking statements. Such information by its nature is subject to numerous risks and uncertainties, any of which could cause the information produced by us to ultimately prove inaccurate. While we include appropriate disclaimers in the reports that we prepare for our clients, once we produce such written work product, we do not always have the ability to control the manner in which our clients use such information. As a result, if our clients reproduce such information to solicit funds from investors for projects without appropriate disclaimers or the information proves to be incorrect, or if our clients reproduce such information for potential investors in a misleading or incomplete manner, our clients or such investors may threaten to or file suit against us for, among other things, securities law violations.

We have only a limited ability to protect our intellectual property rights, and our failure to protect our intellectual property rights could adversely affect 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 operating 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.

We are subject to stringent and evolving U.S. and foreign laws, regulations, rules, contractual obligations, policies and other obligations related to data privacy and security. Our actual or perceived failure to comply with such obligations could lead to regulatory investigations or actions; litigation (including class claims) and mass arbitration demands; fines and penalties; disruptions of our business operations; reputational harm; loss of revenue or profits; loss of customers or sales; and other adverse business consequences.

We develop, install and maintain information technology systems for ourselves, as well as for customers. Client contracts for the performance of information technology services, as well as various privacy and securities laws, require us to manage and protect sensitive and confidential information, including federal and other government information, from disclosure. We also need to protect our own internal trade secrets and other business confidential information, as well as personal data of our employees and contractors, from disclosure.
