TETRA TECH, INC.
Notes to Consolidated Financial Statements
1. Basis of Presentation
The accompanying unaudited consolidated financial statements and related notes of Tetra Tech, Inc. (“we,” “us,” “our” or "Tetra Tech") have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. They do not include all of the information and footnotes required by U.S. GAAP for complete financial statements and, therefore, should be read in conjunction with the audited consolidated financial statements and the notes contained in our Annual Report on Form 10-K for the fiscal year ended September 28, 2025.
These financial statements reflect all normal recurring adjustments that are considered necessary for a fair statement of our financial position, results of operations and cash flows for the interim periods presented. The results of operations and cash flows for any interim period are not necessarily indicative of results for the full fiscal year or for future fiscal years. Certain prior year amounts have been reclassified to conform to the current year presentation in the accompanying notes.
Beginning in fiscal 2026, we transferred certain operating units between our two reportable segments and redefined our reporting units to better align our operations with the clients, markets and geographies that they serve. Prior year amounts for reportable segments have been revised to conform to the current year presentation.
2. Recent Accounting Pronouncements
In September 2025, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) No. 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which clarifies and modernizes the accounting for costs related to internal-use software guidance in subtopic 350-40. The guidance removes all references to project stages throughout Accounting Standards Codification ("ASC") 350-40 and clarifies the threshold entities apply to begin capitalizing costs. The amendments in this ASU are effective for annual periods beginning after December 15, 2027 (fiscal 2029 for us). Early adoption is permitted. We are currently evaluating the impact of this guidance on our consolidated financial statements; however, we do not plan to adopt it before fiscal 2029.
In July 2025, the FASB issued ASU No. 2025-05, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Loss for Accounts Receivable and Contract Assets, which provides a practical expedient (for all entities) and an accounting policy election (for all entities, other than public business entities, that elect the practical expedient) related to the estimation of expected credit losses for current accounts receivable and current contract assets that arise from transactions accounted for under ASC Topic 606, "Revenue from Contracts with Customers". The amendments in this ASU are effective for annual periods beginning after December 15, 2025 (fiscal 2027 for us). Early adoption is permitted. We are currently evaluating the impact of this guidance on our consolidated financial statements; however, we do not plan to adopt it before fiscal 2027.
In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires that an entity, on an annual basis, disclose additional income tax information, primarily related to the rate reconciliation and income taxes paid. The amendments in the ASU are intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this ASU are effective for annual periods beginning after December 15, 2024 (fiscal 2026 for us). The adoption of this ASU will not have a material impact on our consolidated financial statements.
In November 2024, the FASB issued ASU No. 2024-03, Income Statement (Topic 220): Reporting Comprehensive Income. ASU 2024-03 does not change or remove current expense presentation requirements within the consolidated statements of income. However, the amendments require disclosure, on an annual and interim basis, of disaggregated information about certain income statement expense line items within the notes to the consolidated financial statements. The amendments in this update are effective for annual reporting periods beginning after December 15, 2026 (fiscal 2028 for us), and interim reporting periods beginning after December 15, 2027 (first quarter of fiscal 2029 for us). Early adoption is permitted. The adoption of this ASU will not have a material impact on our consolidated financial statements.
In November 2024, the FASB issued ASU No. 2024-04, Debt—Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments, which clarifies the requirements related to accounting for the settlement of a debt instrument as an induced conversion. The amendments in this update are effective for annual reporting periods beginning after December 15, 2025, including interim periods within those fiscal years (first quarter of fiscal 2027 for us). Early adoption is permitted. We are currently evaluating the impact of this guidance on our consolidated financial statements; however, we do not plan to adopt this ASU before fiscal 2027.

3. Revenue and Contract Balances
We disaggregate revenue by client sector and contract type, as we believe it best depicts how the nature, timing and uncertainty of our revenue and cash flows are affected by economic factors. The following tables present our revenue disaggregated by client sector and contract type (in thousands):
| Three Months Ended | |||||||||||||||||||||||
| December 28, 2025 | December 29, 2024 | ||||||||||||||||||||||
| Client Sector: | |||||||||||||||||||||||
U.S. federal government (1) | $ | $ | |||||||||||||||||||||

| Contract Type: | |||||||||||||||||||||||
| Fixed-price | $ | $ | |||||||||||||||||||||
| Time-and-materials | |||||||||||||||||||||||
| Cost-plus | |||||||||||||||||||||||
| Total | $ | $ | |||||||||||||||||||||
(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 Australia, Canada and the United Kingdom.
Other than the U.S. federal government, no single client accounted for more than 10% of our revenue for the first quarters of fiscal 2026 and 2025.
Contract Assets and Contract Liabilities
We invoice customers based on the contractual terms of each contract. However, the timing of revenue recognition may differ from the timing of invoice issuance. Contract assets represent revenue recognized in excess of the amounts for which we have the contractual right to bill our customers. Such amounts are recoverable from customers based upon various measures of performance, including achievement of certain milestones or completion of a contract. In addition, many of our time-and-materials arrangements are billed in arrears pursuant to contract terms that are standard within the industry, resulting in contract assets and/or unbilled receivables being recorded, as revenue is recognized in advance of billings. Contract retentions, included in contract assets, represent amounts withheld by clients until certain conditions are met or the project is completed, which may extend beyond one year.
| As of | |||||||||||
| December 28, 2025 | September 28, 2025 | ||||||||||
Contract assets (1) | $ | $ | |||||||||
Contract liabilities - current | ( | ( | |||||||||
Contract liabilities - non-current (2) | ( | ( | |||||||||
| Net contract liabilities | $ | ( | $ | ( | |||||||
(1) Includes $11.0 million and $12.8 million of contract retentions at December 28, 2025 and September 28, 2025, respectively.
(2) Reported under "Other non-current liabilities" on our consolidated balance sheet as of December 28, 2025 and September 28, 2025.
9
For the first quarters of fiscal 2026 and 2025, we recognized revenue of approximately $160 million and $116 million, respectively, from the amounts included in the contract liability balances at the end of fiscal 2025 and 2024, respectively.
Accounts Receivable, Net
Net accounts receivable consisted of the following (in thousands):
| As of | |||||||||||
| December 28, 2025 | September 28, 2025 | ||||||||||
| Billed | $ | $ | |||||||||
| Unbilled | |||||||||||
| Total accounts receivable | |||||||||||
| Allowance for doubtful accounts | ( | ( | |||||||||
| Total accounts receivable, net | $ | $ | |||||||||
Billed accounts receivable represent amounts billed to clients that have not yet been collected. Unbilled accounts receivable, which represent an unconditional right to payment subject only to the passage of time, include unbilled amounts typically resulting from revenue recognized but not yet billed pursuant to contract terms or billed after the period end date. Substantially all of our unbilled receivables at December 28, 2025 are expected to be billed and collected within 12 months. The allowance for doubtful accounts represents amounts that are expected to become uncollectible or unrealizable in the future. We estimate the allowance for uncollectible accounts based on management's consideration of trends in the actual and forecasted credit quality of our clients, including client delinquency and payment history; type of client, such as a government agency or a commercial sector client; and general economic and industry conditions that may affect our clients' ability to pay.
Other than the U.S. federal government, no single client accounted for more than 10% of our accounts receivable at December 28, 2025 and September 28, 2025.
Remaining Unsatisfied Performance Obligation (“RUPO”)
Our RUPO represents a measure of the total dollar value of work to be performed on contracts awarded and in progress. We had $3.9 billion of RUPO at December 28, 2025. Our RUPO increases with awards from new contracts or additions on existing contracts, and decreases as work is performed and revenue is recognized on existing contracts. Our RUPO may also decrease when projects are canceled or modified in scope. We include a contract within our RUPO when the contract is awarded and an agreement on contract terms has been reached.
We expect to satisfy our RUPO at December 28, 2025 over the following periods (in thousands):
| Amount | |||||
| Within 12 months | $ | ||||
Beyond (1) | |||||
| Total | $ | ||||
Although RUPO reflects business that is considered to be firm, cancellations, deferrals or scope adjustments may occur. Our RUPO is adjusted to reflect any known project cancellations, revisions to project scope and cost, foreign currency exchange fluctuations and project deferrals, as appropriate. Our operations and maintenance contracts can generally be terminated by the clients without a substantive financial penalty; therefore, the remaining performance obligations on such contracts are limited to the notice period required for the termination (usually 30 , 60 , or 90 days).

4. Acquisitions and Divestitures
Acquisitions
In the second quarter of fiscal 2025, we acquired Carron + Walsh ("CAW"), based in the Republic of Ireland. CAW delivers project and cost management solutions for large-scale commercial, life science, residential and infrastructure programs across Europe. CAW has valued relationships and framework agreements with life science clients, public sector bodies, housing authorities, financial lenders and private development companies. In the third quarter of fiscal 2025, we also acquired SAGE Group Holdings ("SAGE"), an Australian consulting firm that provides innovative technology and high-quality automation services that optimize operational efficiency and drive digital transformation for commercial and government clients across the municipal water, energy, transportation, defense and manufacturing sectors.
Both CAW and SAGE are included in our Commercial/International Services Group ("CIG") segment. The aggregate fair value of the purchase price of these two acquisitions was $147 million. This amount consisted of $104 million in initial cash payments and $43 million of the estimated fair value of contingent earn-out obligations, with a maximum of $60 million, based on the achievement of specified operating income targets in each of the three years following their respective acquisition dates. The allocation of the $147 million purchase price consists of $13 million to net tangible assets, $14 million to identifiable intangible assets, $4 million to deferred income tax liability and $124 million to goodwill. The purchase price allocations for these acquisitions are preliminary and subject to adjustment as the estimates, assumptions, valuations and other analyses have not yet been finalized in order to make a definitive allocation.
Both of the aforementioned acquisitions in fiscal 2025 were not considered material, individually or in aggregate, to our consolidated financial statements. As a result, no pro forma information has been provided.
The fiscal 2025 goodwill additions from the CAW and SAGE acquisitions reflect the anticipated synergies related to proven systems and technology in project management, cost management, project controls and automation services which will provide superior project outcomes and drive digital transformation for defense, government and commercial customers, as delivered by a workforce with extensive technical expertise. Goodwill additions in fiscal 2025 were not tax deductible.
Intangible assets with finite lives arise from business acquisitions and are amortized based on the period over which the contractual or economic benefit of the intangible assets are expected to be realized on a straight-line basis over the useful lives of the underlying assets, ranging from one to 12 years. These consist of client relations, backlog and trade names. For detailed information regarding our intangible assets, see Note 5, “Goodwill and Intangible Assets”.
Most of our acquisition agreements include contingent earn-out agreements, which are generally based on the achievement of future operating income thresholds. The contingent earn-out arrangements are based on our valuations of the acquired companies and reduce the risk of overpaying for acquisitions if the projected financial results are not achieved. The fair values of any earn-out arrangements are included as part of the purchase price of the acquired companies on their respective acquisition dates. For each transaction, we estimate the fair value of contingent earn-out payments as part of the initial purchase price and record the estimated fair value of contingent consideration as a liability in “Current contingent earn-out liabilities” and “Non-current contingent earn-out liabilities” on the consolidated balance sheets. We consider several factors when determining that contingent earn-out liabilities are part of the purchase price, including the following: (1) the valuation of our acquisitions is not supported solely by the initial consideration paid, and the contingent earn-out formula is a critical and material component of the valuation approach to determining the purchase price; and (2) the former owners of acquired companies that remain as key employees receive compensation other than contingent earn-out payments at a reasonable level compared with the compensation of our other key employees. The contingent earn-out payments are not affected by employment termination.
We measure our contingent earn-out liabilities at fair value on a recurring basis using significant unobservable inputs classified within Level 3 of the fair value hierarchy. We use a probability-weighted discounted income approach as a valuation technique to convert future estimated cash flows to a single present value amount. The significant unobservable inputs used in the fair value measurements are operating income projections over the earn-out period (generally three to five years ) and the probability outcome percentages we assign to each scenario. Significant increases or decreases to either of these inputs in isolation would result in a significantly higher or lower liability, with a higher liability capped by the contractual maximum of the contingent earn-out obligation. Ultimately, the liability will be equivalent to the amount paid, and the difference between the fair value estimate and amount paid will be recorded in earnings. The amount paid that is less than or equal to the contingent earn-out liability on the acquisition date is reflected as cash used in financing activities in our consolidated statements of cash flows. Any amount paid in excess of the contingent earn-out liability on the acquisition date is reflected as cash used in operating activities in our consolidated statements of cash flows.
We review and reassess the estimated fair value of contingent consideration on a quarterly basis, and the updated fair value could differ materially from the initial estimates. Changes in the estimated fair value of our contingent earn-out liabilities related to the time component of the present value calculation are reported in interest expense. Adjustments to the estimated fair value related to changes in all other unobservable inputs are reported in operating income. In the first quarter of fiscal 2026, we evaluated our estimates for contingent consideration liabilities for the remaining earn-out periods for each individual
11
acquisition, which included a review of their financial results to-date, the status of ongoing projects in their RUPO and the inventory of prospective new contract awards.

As of December 28, 2025, the total potential maximum outstanding contingent consideration related to acquisitions was $120.2 million.
Subsequent Event. On January 16, 2026, we acquired Halvik Corp (“Halvik”) headquartered in Vienna, Virginia. With 600 employees, Halvik provides high-end advisory consulting services focused on advanced data analytics, systems modernization and cybersecurity for U.S. federal defense and civilian agencies. Halvik will be included in our Government Services Group (“GSG”) segment. The results of the Halvik acquisition will be included in our consolidated financial statements beginning on its closing date.
Divestiture
In the first quarter of fiscal 2026, we divested our operations in Norway, which were in our CIG segment. We received proceeds of $41.6 million and recognized a non-operating gain of $7.7 million in our consolidated statements of income.
5. Goodwill and Intangible Assets
Beginning in fiscal 2026, we transferred certain operating units between our two reportable segments and redefined our reporting units to better align our operations with the clients and markets that they serve. As a result, we reallocated goodwill between our GSG and CIG reportable segments on a relative fair value basis.
The following table summarizes the changes in the carrying value of goodwill by reportable segment (in thousands):
| GSG | CIG | Total | ||||||||||||||||||
| Balance at September 28, 2025 | $ | $ | $ | |||||||||||||||||
| Goodwill reallocation | ( | |||||||||||||||||||
| Translation adjustments | ||||||||||||||||||||
| Balance at December 28, 2025 | $ | $ | $ | |||||||||||||||||
Translation adjustments resulted from our goodwill amounts in foreign subsidiaries with functional currencies that are different than our reporting currency. The goodwill amounts presented in the table above are net of reductions from historical impairment adjustments. The gross amounts for GSG were $854.3 million and $768.6 million at December 28, 2025 and September 28, 2025, respectively, excluding accumulated impairment of $110.1 1,443.2 million and $1,512.9 million at December 28, 2025 and September 28, 2025, respectively, excluding accumulated impairment of $121.5
We perform our annual goodwill impairment review at the beginning of our fiscal fourth quarter. Our most recent annual review at June 30, 2025 (i.e. the first day of our fourth quarter in fiscal 2025) indicated that we had no impairment of goodwill, and all of our reporting units had estimated fair values that were in excess of their carrying values, including goodwill. At June 30, 2025, we had no reporting units that had estimated fair values that exceeded their carrying values by less than 38 %, except for our Global Development Services reporting unit ("GDS") as described below.
12
We also regularly evaluate whether events and circumstances have occurred that may indicate a potential change in the recoverability of goodwill. We perform interim goodwill impairment reviews between our annual reviews if certain events and circumstances have occurred, such as a deterioration in general economic conditions; an increase in the competitive environment; a change in management, key personnel, strategy or customers; negative or declining cash flows; or a decline in actual or planned revenue or earnings compared with actual and projected results of relevant prior periods.
During the second quarter of fiscal 2025, events and circumstances occurred that indicated a potential change in the recoverability of the goodwill in GDS. GDS provided consulting and engineering services for international development agencies supporting humanitarian programs worldwide. Although several agencies were supported by this work (primarily for the U.S., Australia and United Kingdom governments), over eighty percent of the activity was historically for the United States Agency for International Development ("USAID").
On January 20, 2025, President Trump signed Executive Order 14169, titled "Reevaluating and Realigning United States Foreign Aid", which initiated a 90-day pause on all U.S. foreign development assistance programs to assess their alignment with U.S. foreign policy objectives with few exemptions. Following a six-week review, on February 27, 2025, U.S. Secretary of State Rubio announced the cancellation of 83 % of USAID programs, totaling approximately 5,200 contracts. Subsequently, we were notified that virtually all of our contracts with USAID were terminated for convenience. As a result of these events and circumstances, we performed an interim impairment review of the goodwill in GDS in the second quarter of 2025.
We considered two methods to determine the fair value of the GDS reporting unit: (i) the Income Approach and (ii) the Market Approach. While each of these approaches were initially considered in the valuation of the business enterprise, the nature and characteristic of the reporting unit indicated which approach was most applicable. The Income Approach utilizes the discounted cash flow method, which focuses on the expected cash flow of the reporting unit. In applying this approach, the cash flow available for distribution is calculated for a finite period of years. Cash flow available for distribution is defined, for purposes of this analysis, as the amount of cash that could be distributed as a dividend without impairing the future profitability or operations of the reporting unit. The cash flow available for distribution and the terminal value (the value of the reporting unit at the end of the estimation period) are then discounted to present value to derive an indication of the value of the business enterprise. The Market Approach is comprised of the guideline public company method and guideline transactions method. The guideline company method focuses on comparing the reporting unit to select reasonably similar (or “guideline”) publicly traded companies. Under this method, valuation multiples are (i) derived from the operating data of selected guideline companies; (ii) evaluated and adjusted based on the strengths and weaknesses of the reporting units relative to the selected guideline companies; and (iii) applied to the operating data of the reporting unit to arrive at an indication of value. In the similar transactions method, consideration is given to prices paid in recent transactions that have occurred in the reporting unit’s industry or in related industries.
For the interim impairment analysis of GDS, we utilized the Income Approach as it had the most direct correlation to the specific economics of the reporting unit. The estimated fair value of equity of GDS was made using Level 3 inputs including the estimated discount rate that reflected the level of risk associated with receiving future cash flows and the forecasted long-term growth rates of GDS's revenue and operating income. Based on our analysis, an impairment of $92.4 million was calculated as the deficit between the fair value of equity of the GDS reporting unit as compared to its carrying value, including goodwill of $130.5 million at our fiscal period end for February 2025. As a result, we recorded a non-cash goodwill impairment charge of $92.4 million included in operating income in the second quarter of fiscal 2025. The remaining $38.1 million of goodwill in GDS was primarily supported by our work for the Australia and United Kingdom foreign aid government agencies.
As of the annual impairment review date, the estimated fair value of the GDS reporting unit continued to approximate its carrying value. Accordingly, a future reduction in these governments’ foreign aid budgets could have resulted in additional impairment. The related long-term assets other than goodwill were not material. Effective the first day of fiscal 2026, we eliminated GDS and realigned its remaining operations with other existing reporting units based on their common geographic markets.

On May 5, 2025, our Board of Directors authorized an additional $500 million stock repurchase program in addition to the previous $400 million stock repurchase program authorized on October 5, 2021. In the first quarter of fiscal 2026, we repurchased and settled 1,482,116 shares with an average price of $33.74 per share for a total cost of $50.0 million in the open market. We repurchased and settled 600,007 shares with an average price of $41.67 per share for a total cost of $25.0 million in the open market in the first quarter of fiscal 2025. At December 28, 2025, we had a remaining balance of $547.8 million under our stock repurchase programs.

8. Leases
Our operating leases are primarily for corporate and project office spaces. To a much lesser extent, we have operating leases for vehicles and equipment. Our operating leases have remaining lease terms of one month to ten years , some of which may include options to extend the leases for up to seven years .
We determine if an arrangement is a lease at inception. Operating leases are included in "Right-of-use assets, operating leases", "Short-term lease liabilities, operating leases" and "Long-term lease liabilities, operating leases" in the consolidated balance sheets. Our finance leases are primarily for certain IT equipment and are immaterial.
Right-of-use ("ROU") assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, incremental borrowing rates are used based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset at the commencement date also includes any lease payments made to the lessor at or before the commencement date and initial direct costs less lease incentives received. Lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term.

9. Stockholders’ Equity and Stock Compensation Plans
We recognize the fair value of our stock-based awards as compensation expense on a straight-line basis over the requisite service period in which the award vests. Stock-based compensation expense for the three months ended December 28, 2025 was $8.2 million, compared to $8.1 million for the same period last year. Most of these amounts were included in our selling, general and administrative expenses on our consolidated statements of income. In the first quarter of fiscal 2026, we awarded 311,026 performance share units (“PSUs”) to our non-employee directors and executive officers at an estimated fair value of $35.54 per share on the award date. All PSUs are performance-based and vest, if at all, after the conclusion of the three-year performance period. The number of PSUs that ultimately vest is based 50 % on growth in our diluted earnings per share and 50 % on our relative total shareholder return over the vesting period. Additionally, we awarded 568,455 restricted stock units (“RSUs”) to our non-employee directors, executive officers and employees at a fair value of $35.33 per share on the award date. All executive officer and employee RSUs have time-based vesting over a four-year period, and the non-employee director RSUs vest after one year .

10. Earnings per Share (“EPS”)
Basic EPS is computed by dividing net income available to common stockholders by the weighted-average common shares outstanding for the period. Diluted EPS is computed by dividing net income by the weighted-average number of common shares outstanding and dilutive potential common shares for the period. Potential common shares include the weighted-average dilutive effects of stock-based awards and shares underlying our Convertible Senior Notes (the "Convertible Notes").
For the first quarter of fiscal 2026, our Convertible Notes, described in Note 13, "Long-Term Debt", had no impact on the calculation of dilutive potential common shares, as the price of our common stock did not exceed the conversion price. For the first quarter of fiscal 2025, the Convertible Notes had a dilution impact on the dilutive potential common shares, which was calculated using the if-converted method. The dilution impact was due to the price of our common stock exceeding the conversion price. The related capped call transactions (the "Capped Call Transactions") for both periods were excluded from the calculation of dilutive potential common shares as their effect is anti-dilutive. For the first quarters of fiscal 2026 and 2025, no

11. Income Taxes
The effective tax rates for the first quarters of fiscal 2026 and 2025 were 25.7 % and 94.9 %, respectively. Income tax expense was increased by $0.1 million of excess tax expenses and reduced by $1.0 million of excess tax benefits on share-based payments in the first three months of fiscal 2026 and 2025, respectively. In addition, in the first quarter of fiscal 2026, we recognized a $7.7 million gain from the sale of our operations in Norway as described in Note 4, “Acquisitions and Divestitures”. The gain is not taxable for income tax purposes. In the first quarter of fiscal 2025, we also recognized a $115.0 million non-recurring charge related to legal contingencies as described in Note 16, "Commitments and Contingencies". We determined that $31.3 million of this charge is not tax deductible. Excluding the impact of the excess tax expenses on share-based payments, the gain from sale in the first quarter of fiscal 2026 and the legal contingency charge in the first quarter of fiscal 2025, our effective tax rates in the first three months of fiscal 2026 and 2025 were 27.1 % and 27.8 %, respectively.
At December 28, 2025 and September 28, 2025, the liability for income taxes associated with uncertain tax positions was $53.8 million and $52.8 million, respectively. It is reasonably possible that the amount of the unrecognized benefit with respect to certain of our unrecognized tax positions may significantly decrease within the next 12 months. These liabilities represent our current estimates of the additional tax liabilities that we may be assessed when the related audits are concluded. If these audits are resolved in a manner more unfavorable than our current expectations, our additional tax liabilities could be materially higher than the amounts currently recorded resulting in additional tax expense.
12. Reportable Segments
We manage our operations under two reportable segments, GSG and CIG.
Beginning in fiscal 2026, we transferred certain operating units between our two reportable segments and redefined our reporting units to better align our operations with the clients, markets and geographies that they serve. Prior year amounts for reportable segments have been revised to conform to the current year presentation.
GSG provides high-end consulting and engineering services primarily to U.S. government clients (federal, state and local). GSG supports U.S. government defense and civilian agencies with services in water, environment, sustainable
17
infrastructure, information technology and disaster management. GSG also provides engineering design services for U.S. based federal and municipal clients, especially in water infrastructure, flood protection and solid waste.
CIG primarily provides high-end consulting and engineering services to U.S. commercial clients, and international clients inclusive of the commercial and government sectors. CIG supports commercial clients worldwide in energy, industrial and high performance buildings markets. CIG also provides sustainable infrastructure and related environmental, engineering and project management services to commercial and local government clients across Canada, in Asia Pacific (primarily Australia and New Zealand), Europe, the United Kingdom and Brazil.
Our Chief Executive Officer serves as the chief operating decision maker (“CODM”) and is responsible for evaluating segment performance and allocating resources to our segments. The CODM assesses segment revenue and segment operating income on a monthly basis by comparing actual results against the annual plan. This evaluation supports strategic decisions related to segment profitability, resource allocation, pricing strategies, and cost optimization. The segment operating income is presented before amortization expense associated with acquisitions and other unallocated corporate costs. It is calculated as revenue less subcontractor costs, and other segment items including other costs of revenue and segment selling, general, and administrative expenses.
Certain expenses are not allocated to GSG and CIG segments for purposes of making operating decisions or evaluating financial performance and are reported under corporate expenses. These expenses include amortization of intangibles, goodwill impairment charges, contingent consideration gains and losses, acquisition and integration expenses, certain legal contingency costs, as well as other costs and benefits that our CODM deems to be enterprise in nature. Corporate expenses also include stock-based compensation expense related to corporate employees.
We account for inter-segment revenue and transfers as if they were to third parties; that is, by applying a negotiated fee onto the costs of the services performed. All significant intercompany balances and transactions are eliminated in consolidation.
Our CODM does not use assets by segment to evaluate performance or allocate resources; therefore, we do not provide disclosure of assets by segment. The accounting policies for segment reporting are the same as for our consolidated financial statements. The tables below present financial information of our reportable segments (in thousands):

Additionally, our GSG other segment items include the equity in the net income of investees accounted for by the equity method of $0.2 million and $0.3 million for the first quarters of fiscal 2026 and 2025, respectively. Our CIG other segment items also reflect the equity in the net income of investees accounted for by the equity method of $0.4 million and $0.5 million for the first quarters of fiscal 2026 and 2025, respectively.

On August 22, 2023, we issued $575.0 million in Convertible Notes that bear interest at a rate of 2.25 % per annum payable in arrears on February 15 and August 15 of each year, beginning on February 15, 2024, and mature on August 15, 2028, unless converted, redeemed or repurchased. Prior to May 15, 2028, the Convertible Notes will be convertible at the option of the holders only upon the occurrence of certain events and during certain periods. Thereafter, the Convertible Notes will be convertible at the option of the holders at any time until the close of business on the second scheduled trading day immediately preceding the maturity date.
The initial conversion rate applicable to the Convertible Notes was 25.4275 shares (5.0855 pre-stock split) of our common stock per $1,000 principal amount of the Convertible Notes, which was equivalent to an initial price of approximately
19
$39.33 per share ($196.64 pre-stock split) of our common stock. The conversion rate is subject to adjustment for certain events, including stock splits and issuance of certain stock dividends on our common stock. At December 28, 2025, the applicable conversion rate was 25.4709 shares of common stock per $1,000 principal amount of the Convertible Notes (equivalent to an adjusted conversion price of approximately $39.26 per share of common stock). Upon conversion, we will pay cash up to the aggregate principal amount of the Convertible Notes to be converted and 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, at our election, in respect of the remainder, if any, of our conversion obligation in excess of the aggregate principal amount of the Convertible Notes being converted. In addition, upon the occurrence of a "fundamental change" as defined in the indenture governing the Convertible Notes, holders may require us to repurchase for cash all or any portion of their Convertible Notes at a fundamental change repurchase price equal to 100 % of the principal amount of the Convertible Notes to be repurchased plus any accrued and unpaid interest. If certain corporate events occur prior to the maturity date of the Convertible Notes or if we deliver a notice of redemption, we will, in certain circumstances, increase the conversion rate for a holder who elects to convert its Convertible Notes in connection with such event or notice of redemption.
We will not be able to redeem the Convertible Notes prior to August 20, 2026. On or after August 20, 2026, we have the option to redeem for cash all or any portion of the Convertible Notes if the last reported sale price of our common stock is equal to or greater than 130 % of the conversion price for a specified period of time at a redemption price equal to 100 % of the principal amount of the Convertible Notes to be redeemed, plus any accrued but unpaid interest. In addition, as described in the indenture governing the Convertible Notes, certain events of default including, but not limited to, bankruptcy, insolvency or reorganization, may result in the Convertible Notes becoming due and payable immediately.
Our net proceeds from the offering were approximately $560.5 million after deducting the initial purchasers’ discounts and commissions and offering expenses. We used approximately $51.8 million of the net proceeds to pay the cost of the Capped Call Transactions described below. We used the remaining net proceeds to repay all $185.0 million principal amount outstanding under our revolving credit facility and the remaining $234.4 million principal amount outstanding under our senior secured term loan due 2027 under the Second Amended and Restated Credit Agreement, as well as approximately $89.4 million principal amount outstanding under our senior secured term loan due 2026 under the Third Amended and Restated Credit Agreement.
The Convertible Notes were recorded as a single unit within "Long-term debt" in our consolidated balance sheets as the conversion option within the Convertible Notes was not a derivative that would require bifurcation, and the Convertible Notes did not involve a substantial premium. Transaction costs to issue the Convertible Notes were recorded as direct deductions from the related debt liabilities and are amortized to interest expense using the effective interest method over the terms of the Convertible Notes resulting in an effective annual interest rate of 2.79 %.

Concurrent with the offering of the Convertible Notes, in August 2023, we entered into the Capped Call Transactions. The Capped Call Transactions are expected generally to reduce the potential dilution of our common stock upon conversion of the Convertible Notes and/or offset any cash payments we elect to make in excess of the principal amount of converted Convertible Notes, as the case may be. If, however, the market price per share of our common stock, as measured under the terms of the Capped Call Transactions, exceeds the cap price of the Capped Call Transactions, there would nevertheless be dilution and/or there would not be an offset of such cash payments, in each case, to the extent that such market price exceeds the cap price of the Capped Call Transactions. The cap price of the Capped Call Transactions was initially $51.91 per share ($259.56 pre-stock split), which represented a premium of 65 % over the last reported sale price of our common stock of $31.46
20
per share ($157.31 pre-stock split) on the NASDAQ Global Select Market on August 17, 2023. The cap price is subject to adjustment for certain events, including stock splits and issuance of certain stock dividends on our common stock. At December 28, 2025, the adjusted cap price was approximately $51.82 per share. We recorded the Capped Call Transactions as separate transactions from the issuance of the Convertible Notes. The cost of $51.8 million incurred to purchase the Capped Call Transactions was recorded as a reduction to additional paid-in capital (net of $12.9 million in deferred taxes) on our consolidated balance sheet as of fiscal 2023 year-end.
On February 18, 2022, we entered into Amendment No. 2 to the Second Amended and Restated Credit Agreement (“Second Amended Credit Agreement”) with a total borrowing capacity of $1.05 billion that was scheduled to mature in February 2027. The Second Amended Credit Agreement consisted of a $750 million senior secured, five-year facility that provided for a $250 million term loan facility ("Second Term Loan Facility") and a $500 million revolving credit facility ("Second Revolving Credit Facility"). On October 26, 2022, we entered into a Third Amended and Restated Credit Agreement (“Third Amended Credit Agreement”) that provided for an additional $500 million senior secured term loan facility (Third Term Loan Facility") increasing our total borrowing capacity to $1.55 billion. On January 23, 2023, we drew the entire amount of the $500 million term loan facility which was scheduled to mature in January 2026. On May 5, 2025 we repaid all facilities in full as detailed below.
On May 5, 2025, we entered into a Fourth Amended and Restated Credit Agreement (“Amended Credit Agreement”) with a total borrowing capacity of $1.5 billion that will mature in May 2030. The Amended Credit Agreement is a $1.1 billion senior secured, five-year facility that provides for a $250 million 3-year term loan facility (the “3Y Term Loan Facility”), a $250 million 5-year term loan facility (“the 5Y Term Loan Facility”), and a $600 million revolving credit facility (the “Amended Revolving Credit Facility”). In addition, the Amended Credit Agreement includes a $400 million accordion feature that allows us to increase the Amended Credit Agreement to $1.5 billion subject to lender approval. The 5Y Term Loan Facility will be subject to quarterly amortization of principal, based upon the annual percentages of the original stated amount thereof (Year 1: 0.0%, Year 2: 0.0%, Year 3: 5.0 %, Year 4: 10.0 %, Year 5: 10.0 %), with the first payment being due at the end of the first full fiscal quarter following the second anniversary of the Amendment Effective Date. The Amended Credit Agreement provides for, among other things, (i) refinance indebtedness under our Third Amended Credit Agreement; (ii) finance open market repurchases of common stock, acquisitions, and cash dividends and distributions; and (iii) utilize the proceeds for working capital, capital expenditures and other general corporate purposes. The Amended Credit Agreement provides for a reduction in the pricing levels of the Consolidated Leverage Ratio and the removal of the Secured Overnight Financing Rate ("SOFR") credit spread adjustment. The Amended Revolving Credit Facility includes a $100 million sublimit for the issuance of standby letters of credit, a $20 million sublimit for swingline loans, and a $400 million sublimit for multicurrency borrowings and letters of credit.
The entire 3Y Term Loan Facility and 5Y Term Loan Facility were drawn on May 5, 2025. The proceeds from these term loans were used to pay down our Third Term Loan Facility and the Second Revolving Credit Facility in full on May 5, 2025. We may borrow on the Amended Revolving Credit Facility, at our option, at either (a) a benchmark rate plus a margin that ranges from 1.000 % to 1.750 % per annum, or (b) a base rate for loans in U.S. dollars (the highest of the U.S. federal funds rate plus 0.50 % per annum, the bank’s prime rate or the SOFR rate plus 1.00 %, plus a margin that ranges from 0% to 0.75 % per annum). In each case, the applicable margin is based on our Consolidated Leverage Ratio, calculated quarterly. The 5Y Term Loan Facility is subject to the same interest rate provisions. The 3Y Term Loan Facility was repaid on September 26, 2025. The Amended Credit Agreement expires on May 5, 2030, or earlier at our discretion upon payment in full of loans and other obligations.
At December 28, 2025, we had $270 million in outstanding borrowings under the Amended Credit Agreement, which consisted of $200 million under the 5Y Term Loan Facility and $70 million borrowings under the Amended Revolving Credit Facility. During the three months ended December 28, 2025, the weighted-average interest rate of the outstanding borrowings under the credit facilities was 5.25 %. In addition, we had $0.7 million in standby letters of credit under the Amended Credit Agreement. At December 28, 2025, we had $529.3 million of available credit under the Amended Revolving Credit Facility, all of which could be borrowed without a violation of our debt covenants.
The Amended Credit Agreement contains certain affirmative and restrictive covenants, and customary events of default. The financial covenants provide for a maximum Consolidated Leverage Ratio of 3.50 to 1.00 (total funded debt/EBITDA, as defined in the Amended Credit Agreement) and a minimum Consolidated Interest Coverage Ratio of 3.00 to 1.00 (EBITDA/Consolidated Interest Charges, as defined in the Amended Credit Agreement). Our obligations under the Amended Credit Agreement are guaranteed by certain of our domestic subsidiaries and are secured by first priority liens on (i) the equity interests of certain of our subsidiaries, including those subsidiaries that are guarantors or borrowers under the Amended Credit Agreement, and (ii) the accounts receivable, general intangibles and intercompany loans and those of our subsidiaries that are guarantors or borrowers. At December 28, 2025, we were in compliance with these covenants with a consolidated leverage ratio of 1.24 x and a consolidated interest coverage ratio of 17.31 x.
In addition to the Amended Credit Agreement, we maintain other credit facilities, which may be used for short-term cash advances and bank guarantees. At December 28, 2025, there were no outstanding borrowings under these facilities and the aggregate amount of standby letters of credit outstanding was $55.0 million. As of December 28, 2025, we had no bank overdrafts related to our disbursement bank accounts.

14. Fair Value Measurements
We classified our assets and liabilities that were carried at fair value in one of the following categories:
•Level 1: Quoted market prices in active markets for identical assets or liabilities.
•Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.
•Level 3: Unobservable inputs that are not corroborated by market data.
Contingent Consideration. We measure our contingent earn-out liabilities at fair value on a recurring basis using significant unobservable inputs classified within Level 3 of the fair value hierarchy (see Note 4, "Acquisitions and Divestitures" for further information).
The estimated fair value of our $575 million Convertible Notes was determined based on the trading price of the Convertible Notes as of the last trading day of our first quarter of fiscal 2026. We consider the fair value of the Convertible Notes to be a Level 2 measurement as they are not actively traded in markets.
The carrying values and estimated fair values of our financial instruments that are not recorded at fair value in our consolidated balance sheets, were as follows (in thousands):

16. Commitments and Contingencies
We are subject to certain claims and lawsuits typically filed against the consulting and engineering profession, alleging primarily professional errors or omissions. We carry professional liability insurance, subject to certain deductibles and policy
22
limits, against such claims. However, in some actions, parties are seeking damages that exceed our insurance coverage or for which we are not insured. While management does not believe that the resolution of these claims will have a material adverse effect, individually or in aggregate, on our financial position, results of operations or cash flows, management acknowledges the uncertainty surrounding the ultimate resolution of these matters.
On July 15, 2019, following an initial January 14, 2019 filing, the Civil Division of the United States Attorney's Office of the United States Department of Justice ("the USAO") filed an amended complaint in the intervention of three qui tam actions filed against our wholly-owned subsidiary, Tetra Tech EC, Inc. ("TtEC"), in the U.S. District Court for the Northern District of California ("the Court"). The complaint alleges False Claims Act ("FCA") violations and breach of contract related to TtEC's contracts to perform environmental remediation services at the former Hunters Point Naval Shipyard in San Francisco, California (the "Covered Conduct"). On March 5, 2024, the Court granted the USAO's motion to amend the filing to include additional claims against TtEC under the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA") and common law.
To explore whether a negotiated resolution was possible, TtEC began engaging in discussions with the USAO during the first quarter of fiscal 2025 regarding a potential resolution of all claims. On January 17, 2025, TtEC entered into a settlement agreement with the United States of America, acting through the USAO and on behalf of the Department of the Navy (collectively, the "United States") and also filed a proposed consent decree with the Court, to resolve this litigation.
TtEC entered into the settlement agreement and consent decree to avoid delay, uncertainty and expense of protracted litigation. The settlement agreement and consent decree contain no admission of liability by TtEC. Under the terms of the settlement agreement and consent decree, TtEC agreed to pay the United States $57 million and $40 million for FCA and CERCLA claims, respectively (the "Settlement Amounts"). In the second quarter of fiscal 2025, we paid the $57 million settlement related to the FCA claim. The $40 million CERCLA settlement payment was made in the fourth quarter of fiscal 2025. Upon entry of the consent decree by the Court and the United States' receipt of the Settlement Amounts, the United States released TtEC from any, and all civil or administrative monetary claims for the Covered Conduct under the civil FCA, the CERCLA, and other specified civil statutes and common law theories of liability.
Several ancillary claims brought by third-party private plaintiffs arising from the same services provided by TtEC at Hunters Point are also ongoing. The settlement agreement and consent decree do not resolve these ancillary claims. TtEC has initiated litigation with the insurance carrier with which TtEC maintained liability policies regarding the reasonably possible payment or reimbursement of a significant portion of the Settlement Amounts. TtEC can give no assurances as to what portion, if any, of the Settlement Amounts will be recovered from the insurance carrier.

(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 Australia, Canada and the United Kingdom.
We manage our operations under two reportable segments: Government Services Group reportable segment and Commercial/International Services Group reportable segment.
Government Services Group (“GSG”). GSG provides high-end consulting and engineering services primarily to U.S. government clients (federal, state and local). GSG supports U.S. government defense and civilian agencies with services in water, environment, sustainable infrastructure, information technology and disaster management. GSG also provides engineering design services for U.S. based federal and municipal clients, especially in water infrastructure, flood protection and solid waste.
Commercial/International Services Group (“CIG”). CIG primarily provides high-end consulting and engineering services to U.S. commercial clients, and international clients inclusive of the commercial and government sectors. CIG supports commercial clients worldwide in energy, industrial and high performance buildings markets. CIG also provides sustainable infrastructure and related environmental, engineering and project management services to commercial and local government clients across Canada, in Asia Pacific (primarily Australia and New Zealand), Europe, the United Kingdom and Brazil.

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:
| Three Months Ended | |||||||||||||||||||||||
| December 28, 2025 | December 29, 2024 | ||||||||||||||||||||||

| Cost-plus | 7.9 | 21.2 | |||||||||||||||||||||
| Total | 100.0 | % | 100.0 | % | |||||||||||||||||||
Under fixed-price contracts, clients agree to pay a specified price for our performance of the entire contract or a specified portion of the contract. Under time-and-materials contracts, we are paid for labor at negotiated hourly billing rates and paid for other expenses. Under cost-plus contracts, some of which are subject to a contract ceiling amount, we are reimbursed for allowable costs plus fees, which may be fixed or performance-based. Profitability on these contracts is driven by billable headcount and our cost control. Revenue is recognized by measuring progress over time under Accounting Standards Codification Topic 606, "Revenue from Contracts with Customers". We estimate and measure progress on our contracts over
25
time whereby we compare our total costs incurred on each contract as a percentage of the total expected contract costs. Changes in those estimates could result in the recognition of cumulative catch-up adjustments to the contract’s inception-to-date revenue, costs and profit in the period in which such changes are made. On a quarterly basis, we review and assess our revenue and cost estimates for each significant contract. Changes in revenue and cost estimates could also result in a projected loss that would be recorded immediately in earnings.
Other contract costs include professional compensation and related benefits, together with certain direct and indirect overhead costs such as rents, utilities and travel. Professional compensation represents a large portion of these costs. Our "Selling, general and administrative expenses" ("SG&A") are comprised primarily of marketing and bid and proposal costs, and our corporate headquarters’ costs related to the executive offices, finance, accounting, administration and information technology. Our SG&A expenses also include a portion of stock-based compensation and depreciation of property and equipment related to our corporate headquarters, and the amortization of identifiable intangible assets. Most of these costs are unrelated to specific clients or projects, and can vary as expenses are incurred to support company-wide activities and initiatives.
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.
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 2025, we acquired Carron + Walsh ("CAW"), based in the Republic of Ireland. CAW delivers project and cost management solutions for large-scale commercial, life science, residential and infrastructure programs across Europe. In the third quarter of fiscal 2025, we acquired SAGE Group Holdings ("SAGE"), an Australian consulting firm that provides innovative technology and high-quality automation services that optimize operational efficiency and drive digital transformation for commercial and government clients across the municipal water, energy, transportation, defense and manufacturing sectors. Both CAW and SAGE are included in our CIG segment.
Subsequent Event. On January 16, 2026, we acquired Halvik Corp (“Halvik”) headquartered in Vienna, Virginia. With 600 employees, Halvik provides high-end advisory consulting services focused on advanced data analytics, systems modernization and cybersecurity for U.S. federal defense and civilian agencies. Halvik will be included in our GSG segment.
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 the first quarter of fiscal 2026, we divested our operations in Norway, which were in our CIG segment. We received proceeds of $41.6 million and recognized a non-operating gain of $7.7 million in our consolidated statements of income. In the first quarter of fiscal 2025, we divested a subsidiary in South America and a line of business in Australia, both of which were immaterial.
For detailed information regarding acquisitions, see Note 4, “Acquisitions and Divestitures” of the “Notes to Consolidated Financial Statements”.

OVERVIEW OF RESULTS AND BUSINESS TRENDS
General. For the first quarter of fiscal 2026, our revenue declined 14.8% compared to the prior-year quarter primarily due to fewer international development projects in our U.S. federal government client sector and lower disaster response activity in our U.S. state and local government client sector. Our revenue in the first quarter of fiscal 2026 includes approximately $40 million from our recent acquisitions, that did not have comparable revenue for the same quarter last year.

Our U.S. federal government revenue decline of 45.7% was primarily due to decreased international development activity in the first quarter of fiscal 2026 compared to the first quarter of fiscal 2025. On January 20, 2025, President Trump signed Executive Order 14169, titled "Reevaluating and Realigning United States Foreign Aid", which initiated a 90-day pause on all U.S. foreign development assistance programs to assess their alignment with U.S. foreign policy objectives with few exemptions. Following a six-week review, on February 27, 2025, U.S. Secretary of State Rubio announced the cancellation of 83% of United States Agency for International Development ("USAID") programs, totaling approximately 5,200 contracts. Subsequently, we were notified that virtually all of our contracts with USAID were terminated for convenience with immediate effect and that any remaining international development activity would be administered by the U.S. Department of State ("DOS"). In the first quarter of fiscal 2026, our U.S. federal government revenue included $56.4 million from USAID/DOS programs compared to $283.9 million in the first quarter of last year. We currently expect no significant USAID/DOS revenue in the remainder of fiscal 2026. However, we do expect our U.S. federal revenue to grow for the remainder of this fiscal year, excluding USAID/DOS activities.

Our U.S. state and local government revenue declined 15.5% compared to the fiscal 2025 quarter due to decreased disaster response activity primarily related to Hurricanes Helene and Milton, which occurred in September and October of 2024, respectively. Excluding this disaster response work, our U.S. state and local government revenue increased 10.3% in the first quarter of fiscal 2026 compared to the first quarter of fiscal 2025. This growth was due to continued investment by our clients in municipal water infrastructure, including digital water automation. Most of our work for the U.S. state and local governments relates to critical water and environmental programs, which we expect to continue to grow in the remainder of fiscal 2026.

Our U.S. commercial revenue declined 3.5% in the first quarter of fiscal 2026 primarily due to lower activity related to renewable energy, partially offset by increased power transmission services compared to the first quarter of fiscal 2025.

For the first quarter of fiscal 2026, our international revenue growth of 12.3% reflects increased activities for water utilities including digital water projects, partially offset by decreased infrastructure activities in Australia. Excluding the revenue from fiscal 2025 acquisitions, our international revenue increased 3.5% in the first quarter of fiscal 2026 compared to the fiscal 2025 quarter. We expect the growth in our international work to continue for the remainder of fiscal 2026.

(1) We believe that the presentation of "Revenue, net of subcontractor costs", which is a non-U.S. GAAP financial measure, enhances investors' ability to analyze our business trends and performance because it substantially measures the work performed by our employees. In the course of providing services, we routinely subcontract various services and, under certain international development programs, issue grants. Generally, these subcontractor costs and grants are passed through to our clients and, in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP") and industry practice, are included in our revenue when it is our contractual responsibility to procure or manage these activities. Because subcontractor services can vary significantly from project to project and period to period, changes in revenue may not necessarily be indicative of our business trends. Accordingly, we segregate subcontractor costs from revenue to promote a better understanding of our business by evaluating revenue exclusive of costs associated with external service providers.
NM = not meaningful
Our revenue decline in the first quarter of fiscal 2026 primarily reflects decreased revenue in our GSG reportable segment due to the aforementioned reduction in USAID/DOS international development activities. Our GSG segment's revenue and revenue, net of subcontractor costs, declined $265.8 million, or 33.6%, and $215.3 million, or 33.3%, respectively, compared to last year. Our CIG segment's revenue increased $59.3 million, or 9.2%, and revenue, net of subcontractor costs, increased $55.1 million, or 10.0% in the first quarter of fiscal 2026 compared to the first quarter of fiscal 2025. The results for GSG and CIG segments are described below under "Government Services Group" and "Commercial/International Group", respectively.
The following table reconciles our reported results to non-GAAP adjusted results. For the first quarter of fiscal 2026, our adjusted results exclude adjustments to contingent consideration liabilities and the earnings per share ("EPS") contribution from the aforementioned non-operating gain from the sale of our operations in Norway. Additionally, for the first quarter of fiscal 2025, our adjusted results exclude a non-recurring charge of $115.0 million related to legal contingencies as described in Note 16, "Commitments and Contingencies" of the “Notes to Consolidated Financial Statements”. We determined that there were no income tax expense for the non-operating gain in the first quarter of fiscal 2026 and no tax benefit for $31.3 million of the legal contingency charge in the first quarter of fiscal 2025. The effective tax rates applied to the remaining adjustments to arrive at the adjusted EPS were 27.5% and 25.0% for the first quarters of fiscal 2026 and 2025, respectively. We applied the relevant marginal statutory tax rate based on the nature of the adjustment and the tax jurisdiction in which it occurred. Both EPS and adjusted EPS were calculated using the diluted weighted-average common shares outstanding for the respective periods as reflected in our Consolidated Statements of Income.

Excluding the non-recurring charges and the earn-out gains, our operating income declined $3.6 million, or 2.6% in the first quarter of fiscal 2026 compared to last year's quarter. The decrease reflects lower results in our GSG reportable segment, partially offset by improved results in our CIG reportable segment, which are described below under "Government Services Group" and "Commercial/International Group", respectively.

The effective tax rates for the first quarters of fiscal 2026 and 2025 were 25.7% and 94.9%, respectively. Income tax expense was increased by $0.1 million of excess tax expenses and reduced by $1.0 million of excess tax benefits on share-based payments in the first three months of fiscal 2026 and 2025, respectively. In addition, in the first quarter of fiscal 2026, we recognized a $7.7 million gain from the sale of our operations in Norway as described in Note 4, “Acquisitions and Divestitures” of the “Notes to Consolidated Financial Statements”. The gain is not taxable for income tax purposes. In the first quarter of fiscal 2025, we also recognized a $115.0 million non-recurring charge related to legal contingencies as described in Note 16, "Commitments and Contingencies" of the “Notes to Consolidated Financial Statements”. We determined that $31.3 million of this charge is not tax deductible. Excluding the impact of the excess tax expenses on share-based payments, the gain from sale in the first quarter of fiscal 2026 and the legal contingency charge in the first quarter of fiscal 2025, our effective tax rates in the first three months of fiscal 2026 and 2025 were 27.1% and 27.8%, respectively.
On January 5, 2026, the Organisation for Economic Cooperation and Development released additional Pillar Two administrative guidance on the Global Anti-Base Erosion “GloBE” Model Rules. This “Side-by-Side” package includes a permanent Simplified Effective Tax Rate (ETR) Safe Harbour, a one-year extension of the Transitional Country-by-Country Reporting (CbCR) Safe Harbour; a Substance-based tax incentive (SBTI) Safe Harbour; a Side-by-Side (SbS) Safe Harbour and an Ultimate Parent Entity (UPE) Safe Harbour for eligible countries. We are continually monitoring developments and evaluating the potential impacts. At this time, we do not anticipate a material tax charge in fiscal 2026.

Segment Results of Operations
Beginning in fiscal 2026, we transferred certain operating units between our two reportable segments and redefined our reporting units to better align our operations with the clients and markets that they serve. Prior year amounts for reportable segments have been revised to conform to the current year presentation.

For the first quarter of fiscal 2026, the revenue decrease of 33.6% compared to the prior-year quarter primarily reflects a revenue decline of approximately $222 million related to the aforementioned cancellation of contracts with USAID.
Operating income decreased primarily due to the aforementioned revenue decline. However, our operating margin, based on revenue, net of subcontractor costs, increased to 16.5% in the first quarter of fiscal 2026 compared to 14.2% in the prior-year quarter. The increased operating margin reflects improved project execution and the elimination of the lower margin cost-reimbursable revenue with USAID.

The revenue growth of 9.2% in first quarter of fiscal 2026 compared to last year's first quarter reflects increased activities for water utilities including digital water projects, primarily in the United Kingdom, partially offset by decreased infrastructure activities in Australia. The increase also includes the aforementioned revenue in the first quarter of fiscal 2026 from our fiscal 2025 acquisitions, that did not have comparable revenue for the same quarter last year. Excluding the revenue from acquisitions, our revenue increased to approximately 3% in the first quarter of fiscal 2026.
Our operating income increased due to the aforementioned revenue growth. Our operating margin, based on revenue, net of subcontractor costs, improved approximately 40 basis points to 13.0% in the first quarter of 2026 compared to 12.6% for the fiscal 2025 quarter. The improved operating margin was primarily due to our continued focus on high-end consulting services and improved project execution.
Backlog
Backlog generally represents the dollar amount of revenue we expect to realize in the future when we perform the work. The difference between our remaining unsatisfied performance obligation ("RUPO") and backlog relates to contract terms. Specifically, our backlog does not consider the potential impact of termination for convenience clauses within the contracts. The contract term and thus remaining performance obligation on certain of our operations and maintenance contracts,
31
are limited to the notice period required for contract termination (usually 30, 60, or 90 days). The differences between our backlog and RUPO at December 28, 2025 and September 28, 2025 were immaterial (see the table below):

At December 28, 2025, our backlog was $4.0 billion. GSG and CIG reported $1.86 billion and $2.13 billion of backlog, respectively, at December 28, 2025.
Financial Condition, Liquidity and Capital Resources
Capital Requirements. At December 28, 2025, we had $269.4 million of cash and cash equivalents and access to an additional $929.3 million of borrowings available under our credit facility. During the first quarter of fiscal 2026, we generated $72.3 million of cash from operations. Our primary sources of liquidity are cash flows from operations and borrowings under our credit facilities. Our primary uses of cash are to fund working capital, cash dividends, share repurchases, capital expenditures and repayment of debt, as well as to fund acquisitions and earn-out obligations from prior acquisitions. We believe that our existing cash and cash equivalents, operating cash flows and borrowing capacity under our credit agreement, as described below, will be sufficient to meet our capital requirements for at least the next 12 months.

Operating Activities. The $59.2 million increase in cash from operating activities in the first quarter of fiscal 2026 compared to last year's quarter was primarily due to cash collections for work on disaster response activities that were completed in the fourth quarter of fiscal 2025 and on terminated USAID programs.
Investing Activities. Our cash provided by investing activities for the first quarter of fiscal 2026 includes the aforementioned proceeds from the sale of our operations in Norway of $41.6 million.
Financing Activities. The $30.3 million change in financing activities primarily reflects share repurchases of $50 million in the first quarter of fiscal 2026 compared to $25 million in the first quarter of fiscal 2025.
Debt Financing. On February 18, 2022, we entered into Amendment No. 2 to the Second Amended and Restated Credit Agreement (“Second Amended Credit Agreement”) with a total borrowing capacity of $1.05 billion that was scheduled to mature in February 2027. The Second Amended Credit Agreement consisted of a $750 million senior secured, five-year facility that provided for a $250 million term loan facility ("Second Term Loan Facility") and a $500 million revolving credit facility ("Second Revolving Credit Facility"). On October 26, 2022, we entered into a Third Amended and Restated Credit Agreement (“Third Amended Credit Agreement”) that provided for an additional $500 million senior secured term loan facility ("Third Term Loan Facility") increasing our total borrowing capacity to $1.55 billion. On January 23, 2023, we drew the entire
32
amount of the $500 million term loan facility which was scheduled to mature in January 2026. On May 5, 2025 we repaid all facilities in full as detailed below.
On August 22, 2023, we issued $575.0 million in Convertible Notes that bear interest at 2.25% per annum payable semiannually in arrears on February 15 and August 15 of each year, beginning on February 15, 2024 with a maturity date of August 15, 2028. The net proceeds from the Convertible Notes were $560.5 million, $51.8 million of which were used to purchase related capped call transactions on the issue date. The remaining proceeds were used to prepay and terminate the $234.4 million outstanding under the Second Term Loan Facility, to prepay $89.4 million outstanding under the Third Term Loan Facility and to pay down borrowings of $185.0 million under the Second Revolving Credit Facility. See Note 13, "Long-Term Debt" of the "Notes to Consolidated Financial Statements" for further discussion.
On May 5, 2025, we entered into a Fourth Amended and Restated Credit Agreement (“Amended Credit Agreement”) with a total borrowing capacity of $1.5 billion that will mature in May 2030. The Amended Credit Agreement is a $1.1 billion senior secured, five-year facility that provides for a $250 million 3-year term loan facility (the “3Y Term Loan Facility”), a $250 million 5-year term loan facility (“the 5Y Term Loan Facility”), and a $600 million revolving credit facility (the “Amended Revolving Credit Facility”). In addition, the Amended Credit Agreement includes a $400 million accordion feature that allows us to increase the Amended Credit Agreement to $1.5 billion subject to lender approval. The 5Y Term Loan Facility will be subject to quarterly amortization of principal, based upon the annual percentages of the original stated amount thereof (Year 1: 0.0%, Year 2: 0.0%, Year 3: 5.0%, Year 4: 10.0%, Year 5: 10.0%), with the first payment being due at the end of the first full fiscal quarter following the second anniversary of the Amendment Effective Date. The Amended Credit Agreement provides for, among other things, (i) refinance indebtedness under our Third Amended Credit Agreement; (ii) finance open market repurchases of common stock, acquisitions, and cash dividends and distributions; and (iii) utilize the proceeds for working capital, capital expenditures and other general corporate purposes. The Amended Credit Agreement provides for a reduction in the pricing levels of the Consolidated Leverage Ratio and the removal of the Secured Overnight Financing Rate ("SOFR") credit spread adjustment. The Amended Revolving Credit Facility includes a $100 million sublimit for the issuance of standby letters of credit, a $20 million sublimit for swingline loans, and a $400 million sublimit for multi-currency borrowings and letters of credit.
The entire 3Y Term Loan Facility and 5Y Term Loan Facility were drawn on May 5, 2025. The proceeds from these term loans were used to pay down our Third Term Loan Facility and the Second Revolving Credit Facility in full on May 5, 2025. On September 26, 2025, the 3Y Term Loan Facility was repaid in full. We may borrow on the Amended Revolving Credit Facility, at our option, at either (a) a benchmark rate plus a margin that ranges from 1.000% to 1.750% per annum, or (b) a base rate for loans in U.S. dollars (the highest of the U.S. federal funds rate plus 0.50% per annum, the bank’s prime rate or the SOFR rate plus 1.00%, plus a margin that ranges from 0% to 0.75% per annum). In each case, the applicable margin is based on our Consolidated Leverage Ratio, calculated quarterly. The 5Y Term Loan Facility is subject to the same interest rate provisions. The Amended Credit Agreement expires on May 5, 2030, or earlier at our discretion upon payment in full of loans and other obligations.
At December 28, 2025, we had $270 million in outstanding borrowings under the Amended Credit Agreement, which consisted of $200 million under the 5Y Term Loan Facility and $70 million borrowings under the Amended Revolving Credit Facility. For the first quarter of fiscal 2026, the weighted-average interest rate of the outstanding borrowings under the credit facilities was 5.25%. In addition, we had $0.7 million in standby letters of credit under the Amended Credit Agreement. At December 28, 2025, we had $529.3 million of available credit under the Amended Revolving Credit Facility, all of which could be borrowed without a violation of our debt covenants.
The Amended Credit Agreement contains certain affirmative and restrictive covenants, and customary events of default. The financial covenants provide for a maximum Consolidated Leverage Ratio of 3.50 to 1.00 (total funded debt/EBITDA, as defined in the Amended Credit Agreement) and a minimum Consolidated Interest Coverage Ratio of 3.00 to 1.00 (EBITDA/Consolidated Interest Charges, as defined in the Amended Credit Agreement). Our obligations under the Amended Credit Agreement are guaranteed by certain of our domestic subsidiaries and are secured by first priority liens on (i) the equity interests of certain of our subsidiaries, including those subsidiaries that are guarantors or borrowers under the Amended Credit Agreement, and (ii) the accounts receivable, general intangibles and intercompany loans, and those of our subsidiaries that are guarantors or borrowers. At December 28, 2025, we were in compliance with these covenants with a consolidated leverage ratio of 1.24x and a consolidated interest coverage ratio of 17.31x.
In addition to the Amended Credit Agreement, we maintain other credit facilities, which may be used for short-term cash advances and bank guarantees. At December 28, 2025, there were no borrowings under these facilities, and the aggregate amount of standby letters of credit outstanding was $55.0 million. At December 28, 2025, we had no bank overdrafts related to our disbursement bank accounts.
Inflation. We believe our operations have not been, and, in the foreseeable future, are not expected to be, materially adversely affected by inflation or changing prices due to the average duration of our projects and our ability to negotiate prices as contracts end and new contracts begin.
Stock repurchases. On May 5, 2025, our Board of Directors authorized an additional $500 million stock repurchase program in addition to the previous $400 million stock repurchase program authorized on October 5, 2021. In the first quarter
33
of fiscal 2026, we repurchased and settled 1,482,116 shares with an average price of $33.74 per share for a total cost of $50.0 million in the open market. We repurchased and settled 600,007 shares with an average price of $41.67 per share for a total cost of $25.0 million in the open market in the first quarter of fiscal 2025. At December 28, 2025, we had a remaining balance of $547.8 million under our stock repurchase programs.
Dividends. Our Board of Directors has authorized the following dividends in fiscal 2026:
| Dividend Per Share | Record Date | Total Maximum Payment (in thousands) | Payment Date | ||||||||||||||||||||
| November 10, 2025 | $ | 0.065 | December 1, 2025 | $ | 16,937 | December 12, 2025 | |||||||||||||||||
Subsequent Events. On January 26, 2026, our Board of Directors declared a quarterly cash dividend of $0.065 per share payable on February 27, 2026 to stockholders of record as of the close of business on February 12, 2026.
Income Taxes
We evaluate the realizability of our deferred tax assets by assessing the valuation allowance and adjusting the allowance, if necessary. The factors used to assess the likelihood of realization are our forecast of future taxable income and available tax planning strategies that could be implemented to realize the net deferred tax assets. The ability or failure to achieve the forecasted taxable income in the applicable taxing jurisdictions could affect the ultimate realization of deferred tax assets. Based on future operating results in certain jurisdictions, it is unlikely that the current valuation allowance positions of those jurisdictions could be adjusted in the next 12 months.
At December 28, 2025 and September 28, 2025, the liability for income taxes associated with uncertain tax positions was $53.8 million and $52.8 million, respectively.
It is reasonably possible that the amount of the unrecognized benefit with respect to certain of our unrecognized tax positions may significantly decrease within the next 12 months. These liabilities represent our current estimates of the additional tax liabilities that we may be assessed when the related audits are concluded. If these audits are resolved in a manner more unfavorable than our current expectations, our additional tax liabilities could be materially higher than the amounts currently recorded resulting in additional tax expense.
Off-Balance Sheet Arrangements
In the ordinary course of business, we may use off-balance sheet arrangements if we believe that such arrangements would be an efficient way to lower our cost of capital or help us manage the overall risks of our business operations. We do not believe that such arrangements have had a material adverse effect on our financial position or our results of operations.
The following is a summary of our off-balance sheet arrangements:
•Letters of credit and bank guarantees are used primarily to support project performance and insurance programs. We are required to reimburse the issuers of letters of credit and bank guarantees for any payments they make under the outstanding letters of credit or bank guarantees. Our Amended Credit Agreement and additional letter of credit facilities cover the issuance of our standby letters of credit and bank guarantees and are critical for our normal operations. If we default on the Amended Credit Agreement or additional credit facilities, our inability to issue or renew standby letters of credit and bank guarantees would impair our ability to maintain normal operations. At December 28, 2025, we had $0.7 million in standby letters of credit outstanding under our Amended Credit Agreement and $55.0 million in standby letters of credit outstanding under our additional letter of credit facilities.
•From time to time, we provide guarantees and indemnifications related to our services. If our services under a guaranteed or indemnified project are later determined to have resulted in a material defect or other material deficiency, then we may be responsible for monetary damages or other legal remedies. When sufficient information about claims on guaranteed or indemnified projects is available and monetary damages or other costs or losses are determined to be probable, we recognize such guaranteed losses.
•In the ordinary course of business, we enter into various agreements as part of certain unconsolidated subsidiaries, joint ventures and other jointly executed contracts where we are jointly and severally liable. We enter into these agreements primarily to support the project execution commitments of these entities. The potential payment amount of an outstanding performance guarantee is typically the remaining cost of work to be performed by or on behalf of third parties under engineering and construction contracts. However, we are not able to estimate other amounts that may be required to be paid in excess of estimated costs to complete contracts and, accordingly, the total potential payment amount under our outstanding performance guarantees cannot be estimated. For cost-plus contracts, amounts that may become payable pursuant to guarantee provisions are normally recoverable from the client for work performed under the contract. For lump sum or fixed-price
34
contracts, this amount is the cost to complete the contracted work less amounts remaining to be billed to the client under the contract. Remaining billable amounts could be greater or less than the cost to complete. In those cases where costs exceed the remaining amounts payable under the contract, we may have recourse to third parties, such as owners, co-venturers, subcontractors or vendors, for claims.
•In the ordinary course of business, our clients may request that we obtain surety bonds in connection with contract performance obligations that are not required to be recorded in our consolidated balance sheets. We are obligated to reimburse the issuer of our surety bonds for any payments made thereunder. Each of our commitments under performance bonds generally ends concurrently with the expiration of our related contractual obligation.
Critical Accounting Policies
Our critical accounting policies are disclosed in our Annual Report on Form 10-K for the fiscal year ended September 28, 2025. To date, there have been no material changes in our critical accounting policies as reported in our fiscal 2025 Annual Report on Form 10-K.
New Accounting Pronouncements
For information regarding recent accounting pronouncements, see “Notes to Consolidated Financial Statements” included in Part I, Item 1 of this Quarterly Report.
Financial Market Risks
We do not enter into derivative financial instruments for trading or speculation purposes. In the normal course of business, we have exposure to both interest rate risk and foreign currency transaction and translation risk, primarily related to the Canadian and Australian dollars, the Euro, and the British Pound.
We are exposed to interest rate risk under our Amended Credit Agreement. We can borrow, at our option, under the 5Y Term Loan Facility and Amended Revolving Credit Facility. We may borrow on the Amended Revolving Credit Facility, at our option, at either (a) a benchmark rate plus a margin that ranges from 1.000% to 1.750% per annum, or (b) a base rate for loans in U.S. dollars (the highest of the U.S. federal funds rate plus 0.50% per annum, the bank’s prime rate or the SOFR rate plus 1.00%, plus a margin that ranges from 0% to 0.75% per annum). In each case, the applicable margin is based on our Consolidated Leverage Ratio, calculated quarterly. The 5Y Term Loan Facility is subject to the same interest rate provisions. The Amended Credit Agreement expires on May 5, 2030, or earlier at our discretion upon payment in full of loans and other obligations. At December 28, 2025, we had $270 million in outstanding borrowings under the Amended Credit Agreement, which consisted of $200 million under the 5Y Term Loan Facility and $70 million borrowings under the Amended Revolving Credit Facility. For the first quarter of fiscal 2026, the weighted-average interest rate of the outstanding borrowings under the Amended Credit Agreement was 5.25%.
The majority of our transactions are in U.S. dollars; however, some of our subsidiaries conduct business in foreign currencies, primarily the Canadian and Australian dollars, the Euro, and British Pound. Therefore, we are subject to currency exposure and volatility because of currency fluctuations. We attempt to minimize our exposure to these fluctuations by matching revenue and expenses in the same currency for our contracts. We report our foreign currency gains and losses in “Selling, general and administrative expenses” on our consolidated statements of income. For the first quarter of fiscal 2026, we reported $1.2 million of foreign currency loss compared to an immaterial amount in the prior year period.
We have foreign currency exchange rate exposure in our results of operations and equity primarily because of the currency translation related to our foreign subsidiaries where the local currency is the functional currency. To the extent the U.S. dollar strengthens against foreign currencies, the translation of these foreign currency denominated transactions will result in reduced revenue, operating expenses, assets and liabilities. Similarly, our revenue, operating expenses, assets and liabilities will increase if the U.S. dollar weakens against foreign currencies. For the first quarters of fiscal 2026 and 2025, 44.7% and 33.9% of our consolidated revenue, respectively, was generated by our international business. For the first quarter of fiscal 2026, the effect of foreign exchange rate translation on our consolidated balance sheet was an increase in equity of $19.7 million compared to a decrease of $108.8 million in the prior-year period. These amounts were recognized as adjustments to equity through other comprehensive income.
