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 29, 2024.

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.

On July 29, 2024, our Board of Directors approved a five-for-one stock split of our common stock. The stock split had a record date of September 5, 2024 and an effective date of September 6, 2024. The par value per share of our common stock remains unchanged at $0.01 per share after the stock split. All prior-period share or per share amounts presented herein have been retroactively adjusted to reflect the stock split.

2. Recent Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires that an entity report segment information in accordance with Topic 280, Segment Reporting. The amendments in the ASU are intended to improve reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. The amendments in this ASU are effective for fiscal years beginning after December 15, 2023 (fiscal 2025 year-end for us), and interim periods within fiscal years beginning after December 15, 2024 (first quarter of fiscal 2026 for us). Early adoption is permitted. The adoption of this ASU will not have a material impact on our consolidated financial statements.

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). 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. 2024-03, 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 29, 2024		December 31, 2023

Client Sector:
U.S. federal government (1)	$	501,848	$	382,076
U.S. state and local government	202,987		150,925
U.S. commercial	233,591		222,430
International (2)	482,135		472,836
Total	$	1,420,561	$	1,228,267

Contract Type:
Fixed-price	$	519,822	$	471,442
Time-and-materials	598,948		549,651
Cost-plus	301,791		207,174
Total	$	1,420,561	$	1,228,267

(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 United Kingdom, Australia and Canada

Other than the U.S. federal government, no single client accounted for more than 10% of our revenue for the first quarters of fiscal 2025 and 2024.

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.

Contract liabilities consist of billings in excess of revenue recognized. Contract liabilities decrease as we recognize revenue from the satisfaction of the related performance obligation and increase as billings in advance of revenue recognition occur. Contract assets and liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period. There were no substantial non-current contract assets for the periods presented. Net contract assets/liabilities consisted of the following (in thousands):


	As of
	December 29, 2024		September 29, 2024

Contract assets (1)	$	122,310	$	129,678
Contract liabilities - current	(359,957)		(351,738)
Contract liabilities - non-current (2)	(8,035)		—
Net contract liabilities	$	(245,682)	$	(222,060)

(1) Includes $8.4 million and $7.9 million of contract retentions at December 29, 2024 and September 29, 2024, respectively.

(2) Reported under "Other non-current liabilities" on our consolidated balance sheet as of December 29,2024.

Our contract assets decreased, and contract liabilities increased in the first quarter of fiscal 2025 compared to fiscal 2024 year-end, due to the timing of our milestone billings on fixed-price contracts which were different from the timing of revenue recognition on those contracts. For the first three months of fiscal 2025 and 2024, we recognized revenue of approximately $116 million and $130 million, respectively, from the amounts included in the contract liability balances at the end of fiscal 2024 and 2023, respectively.

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 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. As a result, in the first quarters of fiscal 2025 and 2024, we recognized net favorable revenue and operating income adjustments of $2.7 million and $5.7 million, respectively.

Changes in revenue and cost estimates could also result in a projected loss, determined at the contract level, which would be recorded immediately in earnings. At December 29, 2024 and September 29, 2024, our consolidated balance sheets included liabilities for anticipated losses of $13.2 million and $15.1 million, respectively. The estimated cost to complete these related contracts was approximately $96 million and $101 million at December 29, 2024 and September 29, 2024, respectively.

Accounts Receivable, Net

Net accounts receivable consisted of the following (in thousands):


	As of
	December 29, 2024		September 29, 2024

Billed	$	707,357	$	707,406
Unbilled	414,778		348,907
Total accounts receivable	1,122,135		1,056,313
Allowance for doubtful accounts	(4,469)		(4,852)
Total accounts receivable, net	$	1,117,666	$	1,051,461

Billed accounts receivable represent amounts billed to clients that have not 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 29, 2024 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 determine an estimated allowance for uncollectible accounts based on management's consideration of trends in the actual and forecasted credit quality of our clients, including delinquency and payment history; type of client, such as a government agency or a commercial sector client; and general economic and industry conditions, which 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 29, 2024 and September 29, 2024.

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 $5.4 billion of RUPO at December 29, 2024. 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 29, 2024 over the following periods (in thousands):


	Amount

Within 12 months	$	3,673,959
Beyond	1,717,412
Total	$	5,391,371

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

clients. In the third quarter of fiscal 2024, we also acquired Convergence Controls & Engineering ("CCE"), an industry leader in process automation and systems integration solutions. CCE’s expertise includes customized digital controls and software solutions, advanced data analytics, cloud data integration, and cybersecurity applications. Both LST and CCE are included in our Government Services Group ("GSG") segment. The aggregate fair value of the purchase price of these two acquisitions was $120 million. This amount consisted of $93 million in initial cash payments, $4 million of cash holdback related to a tax reserve, and $23 million for the estimated fair value of contingent earn-out obligations, with a maximum of $60 million, based upon the achievement of specified operating income targets in each of the three years following the acquisition dates. The $120 million purchase price was allocated $12 million to net tangible assets, $23 million to identifiable intangible assets, and $85 million to goodwill. The purchase price allocation is 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. The results of LST and CCE have been included in our consolidated financial statements since the beginning of their respective closing dates. These acquisitions were not considered material, individually or in aggregate, to our consolidated financial statements. As a result, no pro forma information has been provided.

Our fiscal 2024 goodwill additions from the LST and CCE acquisitions reflect the extensive technical knowledge of the acquired workforces, the anticipated synergies in data analytics, cybersecurity and digital transformation services, and collective reputations of these acquisitions in providing mission critical solutions to both commercial and government customers. These goodwill additions are deductible for tax purposes.

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 2025, we evaluated our estimates for contingent consideration liabilities for the remaining earn-out periods for each individual 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.

In the first quarters of fiscal 2025 and 2024, we recorded immaterial adjustments, individually and in aggregate, to our contingent earn-out liabilities and included the corresponding amount in our operating income.

The following table summarizes the changes in the fair value of estimated contingent consideration (in thousands):


	Three Months Ended
	December 29, 2024		December 31, 2023

Beginning balance	$	48,746	$	73,422

Payments of contingent consideration	(2,865)		(18,862)
Adjustments to fair value recorded in earnings	(366)		(37)
Interest accretion expense	645		471

Ending balance	$	46,160	$	55,604

Maximum potential payout at end of period	$	99,006	$	92,253

5. Goodwill and Intangible Assets

The following table summarizes the changes in the carrying value of goodwill by reportable segment (in thousands):


	GSG		CIG		Total

Balance at September 29, 2024	$	750,817	$	1,295,752	$	2,046,569


Translation adjustments	(4,124)		(73,761)		(77,885)
Balance at December 29, 2024	$	746,693	$	1,221,991	$	1,968,684

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 $764.4 million and $768.5 million at December 29, 2024 and September 29, 2024, respectively, excluding accumulated impairment of $17.7 million at each date. The gross amounts of goodwill for Commercial/International Services Group ("CIG") were $1,343.5 million and $1,417.3 million at December 29, 2024 and September 29, 2024, respectively, excluding accumulated impairment of $121.5 million at each period end.

We perform our annual goodwill impairment review at the beginning of our fiscal fourth quarter. Our most recent annual review at July 1, 2024 (i.e. the first day of our fourth quarter in fiscal 2024) indicated that we had no impairment of goodwill, and all of our reporting units had estimated fair values that were in excess of their carrying values, including goodwill. At July 1, 2024, we had no reporting units that had estimated fair values that exceeded their carrying values by less than 72%.

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. Although we believe that our estimates of fair value for these reporting units are reasonable, if financial performance for these reporting units falls significantly below our expectations or market prices for similar business decline, the goodwill for these reporting units could become impaired.

The following table presents the gross amount and accumulated amortization of our acquired identifiable intangible assets with finite useful lives included in “Intangible assets, net” on the consolidated balance sheets ($ in thousands):

Accumulated depreciation	(112,859)		(110,888)
Property and equipment, net	$	67,102	$	73,065

For the first quarters of fiscal 2025 and 2024, our depreciation expense related to property and equipment was $5.4 million and $7.0 million, respectively.

7. Stock Repurchase and Dividends

On October 5, 2021, our Board of Directors authorized a stock repurchase program under which we could repurchase up to $400 million of our common stock. In the first quarter of fiscal 2025, 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. We did not repurchase any shares of our common stock in the first quarter of fiscal 2024. At December 29, 2024, we had a remaining balance of $322.8 million under our stock repurchase program.

The following table presents dividends declared and paid in the first quarters of fiscal 2025 and 2024:


Declare Date	Dividend Paid Per Share		Record Date	Payment Date	Dividend Paid (in thousands)
November 11, 2024	$	0.058	November 27, 2024	December 13, 2024	$	15,549





November 13, 2023	$	0.052	November 30, 2023	December 13, 2023	$	13,873

Subsequent Event. On January 27, 2025, our Board of Directors declared a quarterly cash dividend of $0.058 per share payable on February 26, 2025 to stockholders of record as of the close of business on February 12, 2025.

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 five 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.

The components of lease costs are as follows (in thousands):


	Three Months Ended

9. Employee Benefits

In fiscal 2020, the Canadian federal government implemented the Canadian Emergency Wage Subsidy ("CEWS") program in response to the negative impact of the coronavirus disease 2019 pandemic on businesses operating in Canada. Some of our Canadian legal entities qualified for and applied for these CEWS cash benefits to partially offset the impacts of revenue reductions and on-going staffing costs. The $21 million total received was initially recorded in "Other long-term liabilities" until all potential amendments to the qualification criteria, including some that were proposed with retroactive application, were finalized in fiscal 2022. In the first quarter of fiscal 2024, we distributed approximately $10 million to our Canadian employees. The remainder was distributed in the first quarter of fiscal 2025. We have no outstanding applications for further government assistance.

10. 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 was $8.1 million and $7.6 million for the first quarters of fiscal 2025 and 2024, respectively. 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 2025, we awarded 236,928 performance share units (“PSUs”) to our non-employee directors and executive officers at an estimated fair value of $49.85 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 481,247 restricted stock units (“RSUs”) to our non-employee directors, executive officers and employees at a fair value of $40.29 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.

11. 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 2025, our Convertible Notes, described in Note 15, "Long-Term Debt", 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. For the first quarter of fiscal 2024, the Convertible Notes had no impact on the calculation of dilutive potential common shares, as the price of our common stock did not exceed 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 2025 and 2024, no options were excluded from the calculation of dilutive potential common shares.

The following table presents the number of weighted-average shares used to compute basic and diluted EPS (in thousands, except per share data):


	Three Months Ended
	December 29, 2024		December 31, 2023

Net income attributable to Tetra Tech	$	747	$	74,972

Weighted-average common shares outstanding – basic	267,854		266,585

Shares issuable assuming conversion of convertible notes	1,872		—
Weighted-average common shares outstanding – diluted	271,886		268,690

Earnings per share attributable to Tetra Tech:
Basic	$	—	$	0.28
Diluted	$	—	$	0.28

12. Income Taxes

The effective tax rates for the first quarters of fiscal 2025 and 2024 were 94.9% and 26.1%, respectively. In the first quarter of fiscal 2025, we recognized a $115 million non-recurring charge related to legal contingencies as described in Note 17, "Commitments and Contingencies". We also determined that $31.3 million of this charge is not tax deductible, which increased our effective tax rate this quarter. Excluding the impact of the legal contingency charge, our effective tax rate was 27.2% in the first quarter of fiscal 2025.

At December 29, 2024 and September 29, 2024, the liability for income taxes associated with uncertain tax positions was $51.1 million and $50.1 million, respectively. It is reasonably possible that the amount of the unrecognized benefit with respect to certain of our unrecognized tax positions may not 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.

13. Reportable Segments

We manage our operations under two reportable segments. Our GSG reportable segment primarily includes activities with U.S. government clients (federal, state and local) and all activities with development agencies worldwide. Our CIG reportable segment primarily includes activities with U.S. commercial clients and international clients other than development agencies.

GSG provides high-end consulting and engineering services primarily to U.S. government clients (federal, state and local) and international development agencies worldwide. GSG supports U.S. government civilian and defense 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. GSG also leads our support for development agencies worldwide, especially in the United States, United Kingdom and Australia.

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 renewable energy, industrial, high performance buildings and aerospace 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 South America (primarily Brazil).

Management evaluates the performance of these reportable segments based upon their respective segment operating income before the effect of amortization expense related to acquisitions, and other unallocated corporate expenses. We account for inter-segment revenues 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 Corporate Segment's operating income in the first quarter of fiscal 2025, includes a non-recurring charge of $115.0 million related to legal contingencies as described in Note 17, "Commitments and Contingencies". This charge is reported separately as "Legal contingency costs" in our consolidated statement of income for the first quarter of fiscal 2025. We expect to pay this amount within the next 12 months with our cash on hand and by drawing on our credit facility.

The following tables summarize financial information regarding our reportable segments (in thousands):


	Three Months Ended
	December 29, 2024		December 31, 2023

Total assets	$	4,179,184	$	4,192,676

(1) Corporate assets consist of intercompany eliminations and assets not allocated to our reportable segments including goodwill, intangible assets, deferred income taxes and certain other assets.

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" for further information).

Debt. The fair value of long-term debt under our Credit Facility was determined using the present value of future cash flows based on the borrowing rates currently available for debt with similar terms and maturities (Level 2 measurement, as described in “Critical Accounting Policies and Estimates” in our Annual Report on Form 10-K for the fiscal year ended September 29, 2024). The carrying value of our long-term debt under our Credit Facility approximated fair value at December 29, 2024 and September 29, 2024. At December 29, 2024, we had $325 million in outstanding borrowings under our Amended Credit Agreement, which consisted of $250 million under the New Term Loan Facility and $75 million under the Amended Revolving Credit Facility.

The estimated fair value of our $575 million Convertible Notes, which were used to fund our business acquisitions, working capital needs, dividends, capital expenditures and contingent earn-outs, was determined based on the trading price of the Convertible Notes as of the last trading day of our first quarter of fiscal 2025. 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 amounts and estimated fair values of the Convertible Notes were approximately $564 million and $673 million, respectively, at December 29, 2024, and $564 million and $743 million, respectively, at September 29, 2024 (see Note 15, "Long-Term Debt" for further information).

15. Long-Term Debt

Long-term debt consisted of the following (in thousands):


	As of
	December 29, 2024		September 29, 2024

Credit facilities	$	325,000	$	250,000
Convertible notes	575,000		575,000
Debt issuance costs and discount	(11,550)		(12,366)
Long-term debt	$	888,450	$	812,634

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 $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 29, 2024, the applicable conversion rate was 25.4345 shares of common stock per $1,000 principal amount of the Convertible Notes (equivalent to an adjusted conversion price of approximately $39.32 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, the remaining $234.4 million principal amount outstanding under our senior secured term loan due 2027 and approximately $89.4 million principal amount outstanding under our senior secured term loan due 2026.

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%.

The net carrying amount of the Convertible Notes was as follows (in thousands):


	As of
	December 29, 2024		September 29, 2024

Principal	$	575,000	$	575,000
Unamortized discount and issuance costs	(10,737)		(11,434)
Net carrying amount	$	564,263	$	563,566

The following table sets forth the interest expense recognized related to the Convertible Notes (in thousands):


	Three Months Ended
	December 29, 2024		December 31, 2023

Interest expense	$	3,234	$	3,270
Amortization of discount and issuance costs	697		678
Total interest expense	$	3,931	$	3,948

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 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 29, 2024, the adjusted cap price was approximately $51.90 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 October 26, 2022, we entered into a Third Amended and Restated Credit Agreement that provides for an additional $500 million senior secured term loan facility (the "New Term Loan Facility") increasing our total borrowing capacity to $1.55 billion. On January 23, 2023, we drew the entire amount of the New Term Loan Facility to partially finance the RPS acquisition. The New Term Loan Facility is not subject to any amortization payments of principal and matures in January 2026.

On February 18, 2022, we entered into Amendment No. 2 to Second Amended and Restated Credit Agreement (“Amended Credit Agreement”) with a total borrowing capacity of $1.05 billion that will mature in February 2027. The Amended Credit Agreement is a $750 million senior secured, five-year facility that provides for a $250 million term loan facility (the “Amended Term Loan Facility”) and a $500 million revolving credit facility (the “Amended Revolving Credit Facility”). In addition, the Amended Credit Agreement includes a $300 million accordion feature that allows us to increase the Amended Credit Agreement to $1.05 billion subject to lender approval. The Amended Credit Agreement provides for, among other things, (i) refinance indebtedness under our Credit Agreement dated at July 30, 2018; (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 interest grid for meeting certain sustainability targets related to the (i) reduction of greenhouse gas emissions through the Company’s projects and operational sustainability initiatives and (ii) improvement of peoples’ lives as a result of the Company’s projects

that provide environmental, social and governance benefits. 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 $300 million sublimit for multicurrency borrowings and letters of credit.

The entire Amended Term Loan Facility was drawn on February 18, 2022. 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 1.875% 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 Secured Overnight Financing Rate ("SOFR") rate plus 1.00%, plus a margin that ranges from 0% to 0.875% per annum. In each case, the applicable margin is based on our Consolidated Leverage Ratio, calculated quarterly. The Amended Term Loan Facility is subject to the same interest rate provisions. The Amended Credit Agreement expires on February 18, 2027, or earlier at our discretion upon payment in full of loans and other obligations. In fiscal 2023, we repaid the Amended Term Loan Facility in full from the Convertible Notes proceeds.

At December 29, 2024, we had $325 million in outstanding borrowings under the Amended Credit Agreement, which was consisted of $250 million under the New Term Loan Facility and $75 million under the Amended Revolving Credit Facility. During the three months ended December 29, 2024, the weighted-average interest rate of the outstanding borrowings under the Amended Credit Agreement was 5.98%. In addition, we had $0.7 million in standby letters of credit under the Amended Credit Agreement. At December 29, 2024, we had $424.3 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 3.25 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 29, 2024, we were in compliance with these covenants with a consolidated leverage ratio of 1.77x and a consolidated interest coverage ratio of 12.33x.

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 29, 2024, there were no outstanding borrowings under these facilities and the aggregate amount of standby letters of credit outstanding was $40.2 million. As of December 29, 2024, we had no bank overdrafts related to our disbursement bank accounts.

17. 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 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.

As we previously disclosed, 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.

Under the terms of the settlement agreement and consent decree, TtEC has agreed to pay the United States $57 million and $40 million for FCA claims and CERCLA claims, respectively (the "Settlement Amounts"), which we expect to pay with cash on hand and by drawing on our credit facility. Upon entry of the consent decree by the Court and the United States' receipt of the Settlement Amounts, the United States will release 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.

The consent decree is subject to a number of contingencies that could prevent it from being finalized with its current terms. In particular, and without limitation, (i) the consent decree is required to be lodged with the Court for a period of 30 days for public notice and comment, and the United States has reserved the right to withdraw or withhold its consent if the comments regarding the consent decree disclose facts or considerations that indicate the consent decree is inappropriate, improper or inadequate; and (ii) the Court might determine not to enter the consent decree as currently written or as approved by the United States. There can be no assurance that the contingencies will not preclude entry of the consent decree.

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.

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.

As also previously disclosed, 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.

As a result of the settlement agreement and consent decree with the United States and in connection with discussions regarding the ancillary claims, we recorded a $115.0 million charge to operating income ($97.0 million for the settlement and $18.0 million estimated for the ancillary claims, respectively) in the first quarter of fiscal 2025.

GENERAL OVERVIEW

Tetra Tech, Inc. is a leading global provider of high-end consulting and engineering services that focuses on water, environment and sustainable infrastructure. We are a global company that is Leading with Science® to provide innovative solutions for our public and private clients. We typically begin at the earliest stage of a project by identifying technical solutions and developing execution plans tailored to our clients' needs and resources.

Our reputation for high-end consulting and engineering services and our ability to develop solutions for water and environmental management has supported our growth for more than 50 years. Today, we are proud to be making a difference in people’s lives worldwide through our high-end consulting, engineering and technology service offerings. We are working on over 100,000 projects, in more than 100 countries on all seven continents, with a talent force of 30,000 associates. We are Leading with Science® throughout our operations, with domain experts across multiple disciplines supported by our advanced analytics, artificial intelligence, machine learning and digital technology solutions.

We are disciplined in our business, and focused on delivering value to customers and high performance for our shareholders. In supporting our clients, we seek to add value and provide long-term sustainable consulting, engineering and technology solutions.

We derive income from fees for professional, technical, program management and construction management services. As primarily a professional services company, we are labor-intensive rather than capital-intensive. Our revenue is driven by our ability to attract and retain qualified and productive employees, identify business opportunities, secure new and renew existing client contracts, provide outstanding services to our clients and execute projects successfully. We provide services to a diverse base of U.S. federal government, U.S. state and local government, U.S. commercial and international clients.

The following table presents the percentage of our revenue by client sector:


	Three Months Ended
	December 29, 2024		December 31, 2023

Client Sector

U.S. commercial	16.5		18.1
International (2)	33.9		38.5
Total	100.0	%	100.0	%

(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 United Kingdom, Australia and Canada.

We manage our operations under two reportable segments. Our Government Services Group reportable segment primarily includes activities with U.S. government clients (federal, state and local) and all activities with development agencies worldwide. Our Commercial/International Services Group reportable segment primarily includes activities with U.S. commercial clients and international clients other than development agencies.

Government Services Group (“GSG”). GSG provides high-end consulting and engineering services primarily to U.S. government clients (federal, state and local) and international development agencies worldwide. GSG supports U.S. government civilian and defense 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. GSG also leads our support for development agencies worldwide, especially in the United States, United Kingdom and Australia.

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 renewable energy, industrial, high performance buildings and aerospace 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 South America (primarily Brazil).

The following table presents the percentage of our revenue by reportable segment:


	Three Months Ended
	December 29, 2024		December 31, 2023

Reportable Segment
GSG	52.9	%	46.8	%
CIG	48.4		54.5
Inter-segment elimination	(1.3)		(1.3)
Total	100.0	%	100.0	%

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 29, 2024		December 31, 2023

Contract Type
Fixed-price	36.6	%	38.4	%
Time-and-materials	42.2		44.7
Cost-plus	21.2		16.9
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 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 2024, we acquired LS Technologies ("LST"), an innovative U.S. federal enterprise technology services and management consulting firm based in Fairfax, Virginia. LST provides high-end consulting and engineering services including advanced data analytics, cybersecurity and digital transformation solutions to U.S. government clients. In the third quarter of fiscal 2024, we also acquired Convergence Controls & Engineering ("CCE"), an industry leader in process automation and systems integration solutions. CCE’s expertise includes customized digital controls and software solutions, advanced data analytics, cloud data integration and cybersecurity applications. Both LST and CCE are included in our GSG segment.

For detailed information regarding acquisitions, see Note 4, “Acquisitions” of the “Notes to Consolidated Financial Statements”.

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 2025, we divested a financially immaterial subsidiary in South America and a line of business in Australia.

OVERVIEW OF RESULTS AND BUSINESS TRENDS

General. In the first quarter of fiscal 2025, our revenue increased 15.7% compared to the prior-year quarter reflecting increased activity across all of our client sectors, particularly the U.S. federal and state and local government client sectors. This revenue growth includes $31 million from our recent acquisitions, that did not have comparable revenue for the year-ago quarter. Excluding the impact of these acquisitions, our revenue increased 13.1% compared to the first quarter of fiscal 2024.

Revenue	$	501,848	$	382,076	$	119,772	31.3%

The 31.3% growth in U.S. federal revenue primarily reflects increased international development and federal information technology system modernization activity. The growth in our international development activity primarily relates to activity in Ukraine to support energy security and other humanitarian needs. Our international development revenue increased approximately $95 million in the first quarter of fiscal 2025 compared to the same period last year. The overall revenue growth also includes approximately $29 million of revenue from a recent acquisition that did not have comparable revenue for the prior-year quarter. Our U.S. federal government revenue for the remainder of fiscal 2025 is dependent upon the ultimate direction of the new U.S. administration.

Our U.S. state and local government revenue grew 34.5% compared to the fiscal 2024 quarter largely due to increased disaster response activity primarily related to Hurricanes Helene and Milton. Excluding our disaster response work for the hurricanes, our U.S. state and local government revenue increased 10.8% in the first quarter of fiscal 2025 compared to last year's first quarter. Excluding the hurricane response activity, the growth was due to continued investment by our clients in clean drinking water. 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 for the remainder of fiscal 2025.

(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 15.7% revenue growth reflects increases in both of our reportable segments. Our GSG segment's revenue and revenue, net of subcontractor costs, increased $176.7 million, or 30.7%, and $158.5 million, or 35.8%, respectively, in the first quarter of fiscal 2025 compared to the same quarter in fiscal 2024. Our CIG segment's revenue increased $19.1 million, or 2.9%, and revenue, net of subcontractor costs, increased $23.7 million, or 4.1% in the first quarter of fiscal 2025 compared to the year-ago quarter. 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-U.S. GAAP adjusted results. 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 17, "Commitments and Contingencies" of the “Notes to Consolidated Financial Statements”. We determined that there is no tax benefit for $31.3 million of the legal contingency charge. The effective tax rate applied to the remaining $83.7 million adjustment to arrive at the adjusted EPS was 25.0%. 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.

Our operating income for the first quarter of fiscal 2025 includes a non-recurring charge of $115.0 million related to legal contingencies. Excluding this non-recurring charge, our adjusted operating income increased $26.4 million, or 23.8% in the first quarter of fiscal 2025 compared to the prior-year quarter. The increase reflects improved results in both of our reportable segments, which are described below under "Government Services Group" and "Commercial/International Group", respectively.

The effective tax rates for the first quarters of fiscal 2025 and 2024 were 94.9% and 26.1%, respectively. In the first quarter of fiscal 2025, we recognized a $115 million non-recurring charge related to legal contingencies as described in Note 17, "Commitments and Contingencies" of the “Notes to Consolidated Financial Statements”. We also determined that $31.3 million of this charge is not tax deductible, which increased our effective tax rate this quarter. Excluding the impact of the legal contingency charge, our effective tax rate was 27.2% for the first quarter of fiscal 2025.

In December 2021, the Organisation for Economic Cooperation and Development ("OECD") released Pillar Two Model Rules (also referred to as the global minimum tax or Global Anti-Base Erosion "GloBE" rules), which were designed to ensure large multinational enterprises pay a minimum 15 percent level of tax on the income arising in each jurisdiction in which they operate. Several jurisdictions in which we operate have enacted these rules, which are effective for the first quarter of fiscal 2025. We are continually monitoring developments and evaluating the potential impacts. At this time, we do not anticipate a material tax charge as a result of implementation of these rules.

(1) Non-GAAP financial measure

The revenue growth of 30.7% primarily reflects higher U.S. federal government activities related to international development and U.S. state and local government activities related to disaster response. The revenue growth in the first quarter of fiscal 2025 includes $87 million and $37 million increases in revenue from the aforementioned international development activities in Ukraine and hurricane disaster response activities, respectively, compared to the first quarter of fiscal 2024.

Operating income increased 31.9% primarily due to the aforementioned revenue growth. Our operating margin, based on revenue, net of subcontractor costs, for the first quarter of fiscal 2025 was 13.9% compared to 14.3% for the same quarter last year. The lower operating margin reflects the mix of revenue as this fiscal year's first quarter included a higher amount of international development activity, which operates at a lower margin compared to the other activities in the GSG segment.

(1) Non-GAAP financial measure

The revenue growth of 2.9% primarily reflects increased activities for water consulting services in the United Kingdom and for high performance buildings. These revenue increases were partially offset by a revenue decrease due to completion of a large infrastructure project for an international government client.

Our operating income increased due to the aforementioned revenue growth. Our operating margin, based on revenue, net of subcontractor costs, for the first quarter of fiscal 2025 was 13.0% compared to 12.5% for the fiscal 2024 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 revenues 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,

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 29, 2024 and September 29, 2024 were immaterial (see the table below):

Financial Condition, Liquidity and Capital Resources

Capital Requirements. At December 29, 2024, we had $248.1 million of cash and cash equivalents and access to an additional $724.3 million of borrowings available under our credit facility. During the first quarter of fiscal 2025, we generated $13.1 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.

Cash and Cash Equivalents. The following tables summarize information regarding our cash and cash equivalents (amounts in thousands):

Operating Activities. Our cash from operations increased $3.8 million compared to the prior-year quarter primarily due to higher earnings, excluding the aforementioned legal contingency charge that was accrued (non-cash) in the current quarter.

Investing Activities. Our cash flows from investing activities for the first quarters of fiscal year 2025 and 2024 reflect capital expenditures of $3.4 million for each period.

Financing Activities. Net cash provided by financing activities of approximately $19 million in the first quarter of fiscal 2025 was substantially the same as the prior-year first quarter. However, our net borrowings increased $10 million in this year's first quarter to partially fund the $25 million share repurchases as our share repurchase program was reactivated this quarter. Our financing activities in the fiscal 2024 first quarter included contingent earn-out payments of $18.9 million compared to essentially none this quarter.

Debt Financing. On October 26, 2022, we entered into a Third Amended and Restated Credit Agreement that provides for an additional $500 million senior secured term loan facility (the "New Term Loan Facility") increasing our total borrowing capacity to $1.55 billion. On January 23, 2023, we drew the entire amount of the New Term Loan Facility to partially finance the RPS acquisition. The New Term Loan Facility is not subject to any amortization payments of principal and matures in January 2026.

On February 18, 2022, we entered into Amendment No. 2 to our Second Amended and Restated Credit Agreement (“Amended Credit Agreement”) with a total borrowing capacity of $1.05 billion that will mature in February 2027. The Amended Credit Agreement is a $750 million senior secured, five-year facility that provides for a $250 million term loan facility (the “Amended Term Loan Facility”) and a $500 million revolving credit facility (the “Amended Revolving Credit Facility”). In addition, the Amended Credit Agreement includes a $300 million accordion feature that allows us to increase the Amended Credit Agreement to $1.05 billion subject to lender approval. The Amended Credit Agreement provides for, among other things, (i) refinance indebtedness under our Credit Agreement dated as of July 30, 2018; (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 interest grid for meeting certain sustainability targets related to the (i) reduction of greenhouse gas emissions through the Company’s projects and operational sustainability initiatives and (ii) improvement of peoples’ lives as a result of the Company’s projects that provide environmental, social and governance benefits. 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 $300 million sublimit for multicurrency borrowings and letters of credit.

On August 22, 2023, we issued $575.0 million in the 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 Amended Term Loan Facility, to prepay $89.4 million outstanding under the New Term Loan Facility and to pay down borrowings of $185.0 million under the Amended Revolving Credit Facility. See Note 15, "Long-Term Debt" of the "Notes to Consolidated Financial Statements" for further discussion.

At December 29, 2024, we had $325 million in outstanding borrowings under the Amended Credit Agreement, which consisted of $250 million under the New Term Loan Facility and $75 million under the Amended Revolving Credit Facility. For the first quarter of fiscal 2025, the weighted-average interest rate of the outstanding borrowings under the Amended Credit Agreement was 5.98%. In addition, we had $0.7 million in standby letters of credit under the Amended Credit Agreement. At December 29, 2024, we had $424.3 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 3.25 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 29, 2024, we were in compliance with these covenants with a consolidated leverage ratio of 1.77x and a consolidated interest coverage ratio of 12.33x.

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 29, 2024, there were no borrowings under these facilities, and the aggregate amount of standby letters of credit outstanding was $40.2 million. At December 29, 2024, 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 October 5, 2021, our Board of Directors authorized a stock repurchase program under which we could repurchase up to $400 million of our common stock. In the first quarter of fiscal 2025, 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. We did not repurchase any shares of our common stock in the first quarter of fiscal 2024. At December 29, 2024, we had a remaining balance of $322.8 million under our stock repurchase program.

Dividends. Our Board of Directors has authorized the following dividends in fiscal 2025:

Subsequent Events. On January 27, 2025, our Board of Directors declared a quarterly cash dividend of $0.058 per share payable on February 26, 2025 to stockholders of record as of the close of business on February 12, 2025.

Income Taxes

We evaluate the realizability of our deferred tax assets by assessing the valuation allowance and adjust 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 29, 2024 and September 29, 2024, the liability for income taxes associated with uncertain tax positions was $51.1 million and $50.1 million, respectively.

It is reasonably possible that the amount of the unrecognized benefit with respect to certain of our unrecognized tax positions may not 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 29, 2024, we had $0.7 million in standby letters of credit outstanding under our Amended Credit Agreement and $40.2 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 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 29, 2024. To date, there have been no material changes in our critical accounting policies as reported in our fiscal 2024 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 both the Amended Term Loan Facility and Amended Revolving Credit Facility. We may borrow on the Amended Revolving Credit Facility, at our option, at either (a) a Eurocurrency rate plus a margin that ranges from 1.000% to 1.875% 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 0.875% per annum. In each case, the applicable margin is based on our Consolidated Leverage Ratio, calculated quarterly. The Amended Term Loan Facility is subject to the same interest rate provisions. Borrowings at the base rate have no designated term and may be repaid without penalty any time prior to the Facility’s maturity date. Borrowings at a SOFR rate have a term no less than 30 days and no greater than 180 days and may be prepaid without penalty. Typically, at the end of such term, such borrowings may be rolled over at our discretion into either a borrowing at the base rate or a borrowing at a SOFR rate with similar terms, not to exceed the maturity date of the Facility. The Facility matures on February 18, 2027. At December 29, 2024, we had $325 million in outstanding borrowings under the Amended Credit Agreement, which was consisted of $250 million under the New Term Loan Facility and $75 million under the Amended Revolving Credit Facility. For the first quarter of fiscal 2025, the weighted-average interest rate of the outstanding borrowings under the Amended Credit Agreement was 5.98%.

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. The impact of the foreign currency gains and losses was immaterial for the first quarters of fiscal 2025 and 2024.

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 2025 and 2024, 33.9% and 38.5% of our consolidated revenue, respectively, was generated by our international business. For the first quarter of fiscal 2025, the effect of foreign exchange rate translation on our consolidated balance sheet was a decrease in equity of $108.8 million compared to an increase of $63.1 million in the prior-year period. These amounts were recognized as adjustments to equity through other comprehensive income.

Item 4. Controls and Procedures

Evaluation of disclosure controls and procedures and changes in internal control over financial reporting. At December 29, 2024, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures. Based on our management’s evaluation (with the participation of our principal executive officer and principal financial officer), our principal executive officer and principal financial officer have concluded that, as of the end of the period covered by this report, our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act), were effective.

Changes in internal control over financial reporting. There were no changes in our internal control over financial reporting that occurred during the quarter ended December 29, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
