TETRA TECH INC

Previous wording

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.

Previous wording

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.

Previous wording

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.

Previous wording

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.

Previous wording

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.

Further, we have and may in the future experience delays in developing and deploying remedial measures and patches designed to address identified vulnerabilities. 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.

Previous wording

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.

Previous wording

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

Current wording

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

Previous wording

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 contracts during regulated procurement processes could harm our operations and significantly reduce or eliminate our profits.

Previous wording

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.

Previous wording

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.

Our fiscal 2025 operating income reflectsa non-cash goodwill impairment charge of $92.4 million related to our Global Development Services reporting unit due to the cancellation of USAID contracts (see Note 6, "Goodwill and Intangible Assets" of the "Notes to Consolidated Financial Statements" included in Item 8). We had no goodwill impairment in fiscal 2024 and 2023.

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.

For example, on July 4, 2025, the U.S. government enacted legislation commonly referred to as the One Big Beautiful Bill Act, which includes changes to the taxation of business entities, and we are evaluating the future impact of certain of these changes on our financial statements. 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.

In the United States, federal, state, and local governments have enacted numerous data privacy and security laws, including data breach notification laws, personal data privacy laws, consumer protection laws (e.g., Section 5 of the Federal Trade Commission Act), and other similar laws. For example, the California Consumer Privacy Act of 2018, as amended by the California Privacy Rights Act of 2020 (collectively, “CCPA”) applies to personal information of consumers, business representatives, and employees who are California residents, and requires businesses to provide specific disclosures in privacy notices and honor requests of such individuals to exercise certain privacy rights. The CCPA provides for administrative fines of up to $7,500 per violation and allows private litigants affected by certain data breaches to recover significant statutory damages. Other states, such as Virginia and Colorado, have also passed comprehensive privacy laws, and similar laws are being considered in several other states, as well as at the federal and local levels.
