We are working on over 100,000 projects, in more than 100 countries on all seven continents, with more than 25,000 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. Our ability to provide innovative and first-of-kind solutions is enhanced by partnerships with our forward-thinking clients. We embrace the breadth of experience across our talented workforce worldwide with a culture of innovation and entrepreneurship. 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 Nine Months Ended June 28, 2026 June 29, 2025 June 28, 2026 June 29, 2025 Client Sector U.S. federal government (1) 25.9 % 33.0 % 24.7 % 33.2 % U.S. state and local government 13.3 13.8 14.0 14.6 U.S. commercial 18.0 16.2 17.8 16.2 International (2) 42.8 37.0 43.5 36.0 Total 100.0 % 100.0 % 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 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. 27 Government Services Group (“GSG”). GSG provides high-end technical 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 technical 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. The following table presents the percentage of our revenue by reportable segment: Three Months Ended Nine Months Ended June 28, 2026 June 29, 2025 June 28, 2026 June 29, 2025 Reportable Segment GSG 45.7 % 51.8 % 45.0 % 53.5 % CIG 55.7 49.4 56.4 47.6 Inter-segment elimination (1.4) (1.2) (1.4) (1.1) Total 100.0 % 100.0 % 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 Nine Months Ended June 28, 2026 June 29, 2025 June 28, 2026 June 29, 2025 Contract Type Fixed-price 48.5 % 46.2 % 48.0 % 40.8 % Time-and-materials 42.0 43.5 43.2 43.8 Cost-plus 9.5 10.3 8.8 15.4 Total 100.0 % 100.0 % 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 nine months 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 28 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 2026, we acquired Halvik Corp (“Halvik”) headquartered in Vienna, Virginia. 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 is included in our GSG segment. In the third quarter of fiscal 2026, we acquired Providence Consulting Group Pty Ltd ("Providence"), an advisory and project management consultancy based in Australia. Providence is included in our CIG segment. In 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 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 CIG 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. In the first quarter of fiscal 2025, we divested a subsidiary in South America and a line of business in Australia. All of these divestitures were not considered material, individually or in aggregate, to our consolidated financial statements. 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 nine months of fiscal 2026, our revenue declined 9.1% compared to the prior-year period primarily due to fewer international development projects in our U.S. federal government client sector. 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 addition, our year-over-year revenue comparisons include lower disaster response activity in both of our U.S. government client sectors. Our revenue in the first nine months of fiscal 2026 includes approximately $180 million from our 29 recent acquisitions (net of the aforementioned Norway disposition), that did not have comparable revenue for the same period last year. The table below presents our revenue by client sector (amounts in thousands): Nine Months Ended June 28, 2026 June 29, 2025 Change $ % Client Sector U.S. federal government (1) $ 923,573 $ 1,367,899 $ (444,326) (32.5)% U.S. state and local government 522,349 599,606 (77,257) (12.9) U.S. commercial 667,450 666,027 1,423 0.2 International (2) 1,626,002 1,478,958 147,044 9.9 Total $ 3,739,374 $ 4,112,490 $ (373,116) (9.1)% (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. U.S. Federal Government. Nine Months Ended June 28, 2026 June 29, 2025 Change $ % ($ in thousands) Revenue $ 923,573 $ 1,367,899 $ (444,326) (32.5)% Our U.S. federal government revenue declined 32.5% primarily due to the aforementioned decreased international development and disaster response activity in the first nine months of fiscal 2026 compared to the same period last year. In the first nine months of fiscal 2026, our U.S. federal government revenue included approximately $190 million from USAID/DOS programs compared to approximately $550 million in the fiscal 2025 period. Additionally, the first nine months of fiscal 2025 included revenue related to our disaster response programs for the Palisades and Eaton fires in Southern California. Our revenue in the first nine months of fiscal 2026 includes approximately $85 million from a recent acquisition, that did not have comparable revenue for the prior-year period. We expect our U.S. federal revenue to grow for the remainder of this fiscal year, excluding USAID/DOS and disaster response activities. U.S. State and Local Government. Nine Months Ended June 28, 2026 June 29, 2025 Change $ % ($ in thousands) Revenue $ 522,349 $ 599,606 $ (77,257) (12.9)% Our U.S. state and local government revenue declined 12.9% compared to the fiscal 2025 period due to decreased disaster response activity primarily related to Hurricanes Helene and Milton. Excluding this disaster response work, our U.S. state and local government, revenue increased approximately 6% in the first nine months of fiscal 2026 compared to the same period last year. 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 for the remainder of fiscal 2026. 30 U.S. Commercial. Nine Months Ended June 28, 2026 June 29, 2025 Change $ % ($ in thousands) Revenue $ 667,450 $ 666,027 $ 1,423 0.2% Our U.S. commercial revenue was stable in the first nine months of fiscal 2026 compared to the same period last year primarily due to increased power transmission services, partially offset by lower activity related to renewable energy. We expect our U.S. commercial revenue, excluding renewable energy, to grow in the fourth quarter of fiscal 2026. International. Nine Months Ended June 28, 2026 June 29, 2025 Change $ % ($ in thousands) Revenue $ 1,626,002 $ 1,478,958 $ 147,044 9.9% For the first nine months of fiscal 2026, our international revenue growth of 9.9% reflects increased activities for water utilities including digital water projects. Excluding the revenue from our fiscal 2025 acquisition and the aforementioned Norway disposition, our international revenue increased approximately 4% in the first nine months of fiscal 2026 compared to the fiscal 2025 period. We expect the growth in our international work to continue for the remainder of fiscal 2026. 31 RESULTS OF OPERATIONS Consolidated Results of Operations Three Months Ended Nine Months Ended June 28, 2026 June 29, 2025 Change June 28, 2026 June 29, 2025 Change $ % $ % ($ in thousands, except per share data) Revenue $ 1,308,555 $ 1,369,816 $ (61,261) (4.5)% $ 3,739,374 $ 4,112,490 $ (373,116) (9.1)% Subcontractor costs (199,996) (216,800) 16,804 7.8 (544,007) (658,439) 114,432 17.4 Revenue, net of subcontractor costs (1) 1,108,559 1,153,016 (44,457) (3.9) 3,195,367 3,454,051 (258,684) (7.5) Other costs of revenue (865,354) (901,477) 36,123 4.0 (2,517,701) (2,766,854) 249,153 9.0 Gross profit 243,205 251,539 (8,334) (3.3) 677,666 687,197 (9,531) (1.4) Selling, general and administrative expenses (85,203) (86,611) 1,408 1.6 (254,653) (255,022) 369 0.1 Legal contingency costs — — — — — (115,000) 115,000 NM Contingent consideration - fair value adjustments (77) 58 (135) (232.8) 7,429 2,355 5,074 215.5 Impairment of goodwill — — — — — (92,416) 92,416 NM Income from operations 157,925 164,986 (7,061) (4.3) 430,442 227,114 203,328 89.5 Interest expense (7,158) (8,288) 1,130 13.6 (23,124) (23,996) 872 3.6 Other non-operating income — — — — 12,361 — 12,361 NM Income before income tax expense 150,767 156,698 (5,931) (3.8) 419,679 203,118 216,561 106.6 Income tax expense (40,966) (42,815) 1,849 4.3 (110,858) (83,045) (27,813) (33.5) Net income 109,801 113,883 (4,082) (3.6) 308,821 120,073 188,748 157.2 Net income attributable to noncontrolling interests (217) (39) (178) (456.4) (586) (94) (492) NM Net income attributable to Tetra Tech $ 109,584 $ 113,844 $ (4,260) (3.7) $ 308,235 $ 119,979 $ 188,256 156.9 Diluted earnings per share $ 0.42 $ 0.43 $ (0.01) (2.3) $ 1.18 $ 0.45 $ 0.73 162.2 (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 in the third quarter and first nine months of fiscal 2026, compared to the same periods last year, primarily reflects decreased revenue in our GSG reportable segment due to the aforementioned reductions in USAID/DOS and disaster response activities. For the third quarter of fiscal 2026, our GSG segment's revenue and revenue, net of subcontractor costs, declined $111.0 million, or 15.6%, and $98.3 million, or 17.2%, respectively, compared to the same quarter last year. Our CIG segment's revenue increased $51.8 million, or 7.7%, and revenue, net of subcontractor costs, increased $53.9 million, or 9.3% in the third quarter of fiscal 2026 compared to the fiscal 2025 third quarter. 32 For the first nine months of fiscal 2026, our GSG segment's revenue and revenue, net of subcontractor costs, declined $516.4 million, or 23.5%, and $419.4 million, or 23.5%, respectively, compared to the year-ago period. Our CIG segment's revenue increased $149.5 million, or 7.6%, and revenue, net of subcontractor costs, increased $160.8 million, or 9.6% in the first nine months of fiscal 2026 compared to the fiscal 2025 period. The third quarter and first nine month 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 nine months of fiscal 2026 and 2025, our adjusted results exclude adjustments to contingent consideration liabilities. Additionally, the first nine months of fiscal 2026 exclude the earnings per share ("EPS") contribution from the aforementioned non-operating gain from the sale of our operations in Norway. For the first nine months of fiscal 2025, our adjusted results exclude a non-cash goodwill impairment charge of $92.4 million that resulted from the aforementioned cancellation of USAID programs. The first nine months of fiscal 2025 also excludes 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 was no income tax expense for the non-operating gain in fiscal 2026, and no tax benefit recognized for $31.3 million of the legal contingency charge or $58.3 million of the goodwill impairment charge in 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 nine months 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.

The changes reflect lower results in our GSG reportable segment and improved results in our CIG reportable segment, which are described below under "Government Services Group" and "Commercial/International Group", respectively. 33 Three Months Ended Nine Months Ended June 28, 2026 June 29, 2025 Change June 28, 2026 June 29, 2025 Change $ % $ % ($ in thousands) Net interest expense $ 7,158 $ 8,288 $ (1,130) (13.6)% $ 23,124 $ 23,996 $ (872) (3.6)% Net interest expense decreased in the third quarter and first nine months of fiscal 2026 compared to the fiscal 2025 periods primarily due to lower borrowings and average debt interest rates.

Income tax expense was reduced by $0.6 million and $1.0 million of excess tax benefits on share-based payments in the first nine months of fiscal 2026 and 2025, respectively. In addition, in the first nine months of fiscal 2026, we recognized a $12.4 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 nine months of fiscal 2025, we recognized a $92.4 million goodwill impairment charge as described in Note 5, Goodwill and Intangible Assets and determined that $58.3 million of the impairment is not deductible for tax purposes. We also recognized a $115.0 million non-recurring charge in the first nine months of fiscal 2025 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 benefits on share-based payments, the gain from sale in the first nine months of fiscal 2026 and the goodwill impairment and legal contingency charge in the first nine months of fiscal 2025, our effective tax rates in the first nine months of fiscal 2026 and 2025 were 27.4% and 27.6%, 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. Government Services Group Three Months Ended Nine Months Ended June 28, 2026 June 29, 2025 Change June 28, 2026 June 29, 2025 Change $ % $ % ($ in thousands) Revenue $ 598,402 $ 709,411 $ (111,009) (15.6)% $ 1,683,260 $ 2,199,636 $ (516,376) (23.5)% Subcontractor costs (124,065) (136,751) 12,686 9.3 (318,358) (415,297) 96,939 23.3 Revenue, net of subcontractor costs (1) $ 474,337 $ 572,660 $ (98,323) (17.2)% $ 1,364,902 $ 1,784,339 $ (419,437) (23.5)% Income from operations $ 82,837 $ 99,718 $ (16,881) (16.9)% $ 229,107 $ 271,414 $ (42,307) (15.6)% (1) Non-GAAP financial measure 34 For the third quarter and first nine months of fiscal 2026, revenue decreased 15.6% and 23.5%, respectively, compared to the prior-year periods primarily due to the aforementioned cancellation of contracts with USAID and lower disaster response activities. Excluding revenue from USAID/DOS and the disaster response revenue, GSG segment revenue increased approximately 6% in the first nine months of fiscal 2026 compared to the same period last year. GSG revenue in the first nine months of fiscal 2026 includes approximately $85 million from a recent acquisition, that did not have comparable revenue for the same period last year. Operating income decreased primarily due to the aforementioned revenue decline. However, GSG operating margin, based on revenue, net of subcontractor costs, increased to 16.8% in the first nine months of fiscal 2026 compared to 15.2% in the prior-year period. The increased operating margin reflects improved project execution and the elimination of the lower margin cost-reimbursable revenue with USAID. Commercial/International Group Three Months Ended Nine Months Ended June 28, 2026 June 29, 2025 Change June 28, 2026 June 29, 2025 Change $ % $ % ($ in thousands) Revenue $ 728,276 $ 676,488 $ 51,788 7.7% $ 2,108,576 $ 1,959,076 $ 149,500 7.6 % Subcontractor costs (94,054) (96,132) 2,078 2.2 (278,111) (289,364) 11,253 3.9 Revenue, net of subcontractor costs (1) $ 634,222 $ 580,356 $ 53,866 9.3% $ 1,830,465 $ 1,669,712 $ 160,753 9.6 % Income from operations $ 95,545 $ 87,112 $ 8,433 9.7% $ 246,517 $ 225,249 $ 21,268 9.4 % (1) Non-GAAP financial measure The revenue growth in the third quarter and first nine months of fiscal 2026, compared to the same periods last year, reflects increased activities for water utilities including digital water projects, primarily in the United Kingdom. The increases also include the aforementioned international revenue in the first nine months of fiscal 2026 from our fiscal 2025 acquisition, that did not have comparable revenue for the fiscal 2025 period. Excluding revenue from the acquisition, net of the aforementioned Norway disposition, CIG revenue increased approximately 3% in the first nine months of fiscal 2026 compared to the first nine months of fiscal 2025. Operating income increased due to the aforementioned revenue growth. CIG operating margin, based on revenue, net of subcontractor costs, was substantially the same in the first nine months of fiscal 2026 compared to same period last year. 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, are limited to the notice period required for contract termination (usually 30, 60, or 90 days). The differences between our backlog and RUPO at June 28, 2026 and September 28, 2025 were immaterial (see the table below): As of June 28, 2026 September 28, 2025 ($ in millions) RUPO $ 4,440 $ 4,101 Backlog 4,490 4,140 At June 28, 2026, our backlog was $4.5 billion. GSG and CIG reported $2.1 billion and $2.4 billion of backlog, respectively, at June 28, 2026. Financial Condition, Liquidity and Capital Resources 35 Capital Requirements. At June 28, 2026, we had $230.8 million of cash and cash equivalents and access to an additional $964.3 million of borrowings available under our credit facility. During the first nine months of fiscal 2026, we generated $466.6 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): As of June 28, 2026 September 28, 2025 Change $ % Cash and cash equivalents $ 230,835 $ 167,459 $ 63,376 37.8 % Nine Months Ended June 28, 2026 June 29, 2025 Change $ % Net cash provided by (used in): Operating activities $ 466,553 $ 356,838 $ 109,715 30.7 % Investing activities (165,562) (108,273) (57,289) (52.9) Financing activities (240,033) (234,987) (5,046) (2.1) Effect of exchange rate changes 1,505 (3,434) 4,939 143.8 Net increase in cash $ 62,463 $ 10,144 $ 52,319 515.8 % Operating Activities. For the first nine months of fiscal 2026, cash from operating activities increased $109.7 million compared to the first nine months of fiscal 2025, primarily due to cash collections related to disaster response activities completed in the fourth quarter of fiscal 2025 and on terminated USAID programs. The increase also reflects a $57 million payment for the aforementioned legal contingency in fiscal 2025. Investing Activities. Our cash used in investing activities for the first nine months of fiscal 2026 includes initial cash payments of $192 million for acquisitions, partially offset by the net proceeds of $40.3 million from the sale of our operations in Norway. Financing Activities. Our cash used in financing activities primarily reflects share repurchases of approximately $200 million in the first nine months of both fiscal 2026 and fiscal 2025. In addition, we paid dividends of $52.5 million and $48.0 million in the first nine months of fiscal 2026 and fiscal 2025, respectively. 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 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 36 $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 June 28, 2026, we had $235 million in outstanding borrowings under the Amended Credit Agreement, which consisted of $200 million under the 5Y Term Loan Facility and $35 million borrowings under the Amended Revolving Credit Facility. For the first nine months of fiscal 2026, the weighted-average interest rate of the outstanding borrowings under the credit facilities was 5.01%. In addition, we had $0.7 million in standby letters of credit under the Amended Credit Agreement. At June 28, 2026, we had $564.3 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 June 28, 2026, we were in compliance with these covenants with a consolidated leverage ratio of 1.24x and a consolidated interest coverage ratio of 18.98x. 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 June 28, 2026, there were no borrowings under these facilities, and the aggregate amount of standby letters of credit outstanding was $48.2 million. At June 28, 2026, 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 nine months of fiscal 2026, we repurchased and settled 6,391,799 shares with an average price of $31.29 per share for a total cost of $200.0 million in the open market. We repurchased and settled 5,933,085 shares with an average price of $33.71 per share for a total cost of $200.0 million in the open market in the first nine months of fiscal 2025. In the first nine months of fiscal 2026, we also paid $2.0 million of excise tax on stock repurchases imposed by the Inflation Reduction Act of 2022. At June 28, 2026, our $400 million stock repurchase program was fully executed and we had a remaining balance of $397.8 million under our $500 million stock repurchase program. 37 Dividends. Our Board of Directors has authorized the following dividends in fiscal 2026: Declare Date Dividend Paid Per Share Record Date Payment Date Dividend Paid (in thousands) November 10, 2025 $ 0.065 December 1, 2025 December 12, 2025 $ 16,937 January 26, 2026 0.065 February 12, 2026 February 27, 2026 16,915 April 27, 2026 0.072 May 14, 2026 June 2, 2026 18,621 Subsequent Event. On July 27, 2026, our Board of Directors declared a quarterly cash dividend of $0.072 per share payable on August 27, 2026 to stockholders of record as of the close of business on August 13, 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 June 28, 2026 and September 28, 2025, the liabilities for income taxes associated with uncertain tax positions were $55.8 million and $52.8 million, respectively. These liabilities represent our current estimates of the additional tax liabilities that 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 June 28, 2026, we had $0.7 million in standby letters of credit outstanding under our Amended Credit Agreement and $48.2 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. 38 •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 June 28, 2026, we had $235 million in outstanding borrowings under the Amended Credit Agreement, which consisted of $200 million under the 5Y Term Loan Facility and $35 million borrowings under the Amended Revolving Credit Facility. For the first nine months of fiscal 2026, the weighted-average interest rate of the outstanding borrowings under the Amended Credit Agreement was 5.01%. 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 nine months of fiscal 2026, we reported $1.5 million of foreign currency loss compared to a loss of $2.3 million in the same period last fiscal year. 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 nine months of fiscal 2026 and 2025, 43.5% and 36.0% of our consolidated revenue, respectively, was generated by our international business. For the first nine months of fiscal 2026, the effect of foreign exchange rate translation on our consolidated balance sheet was a decrease in equity of $9.2 million compared to an increase of $13.8 million in the prior-year period. These amounts were recognized as adjustments to equity through other comprehensive income.
