Computed values are grepcent-computed from the verified facts above and may differ from ratios the company itself reports. Free cash flow = operating cash flow − capital expenditures. Net margin = net income ÷ revenue. Operating margin = operating income ÷ revenue. Revenue YoY = FY2025 revenue ÷ FY2024 revenue − 1 (consecutive fiscal years only). ROE = net income ÷ period-end stockholders' equity.

Percentile = share of the N covered peers reporting that ratio whose value is lower (ties counted half); computed among grepcent-covered companies in SIC major-group 87 SIC Major Group 87, not the whole market. A higher percentile means a higher value of the ratio, not a better company. Ratios with fewer than 8 reporting peers are omitted. Latest reported values per company; fiscal periods may differ. Descriptive arithmetic - not a score, rating, or ranking.

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:

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.

Total100.0%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 EndedNine Months Ended
June 28, 2026June 29, 2025June 28, 2026June 29, 2025

Cost-plus9.510.38.815.4
Total100.0%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

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 assuran

OVERVIEW OF RESULTS AND BUSINESS TRENDS

General. Our revenue growth of 4.7% in fiscal 2025 was primarily due to increased activity in the U.S. state and local and U.S. federal government client sectors. The overall growth includes $80 million from our recent acquisitions, that did not have comparable revenue for fiscal 2024. Excluding the impact of these acquisitions, our revenue increased 3.2% compared to last fiscal year.

The table below presents our revenue by client sector (amounts in thousands):

($ in thousands)
Revenue$1,718,831$1,675,996$42,8352.6%

Our U.S. federal government sector grew 2.6% in fiscal 2025 primarily due to increased disaster response work related to the Palisades and Eaton fires in Southern California, which occurred in early January 2025. The revenue growth also includes approximately $35 million of revenue from recent acquisitions that did not have comparable revenue in fiscal 2024.

On January 20, 2025, President Trump signed Executive Order 14169, titled "Reevaluating and Realigning United States Foreign Aid", which initiated a 90-day pause on all U.S. foreign development assistance programs to assess their alignment with U.S. foreign policy objectives with few exemptions. Following a six-week review, on February 27, 2025, U.S. Secretary of State Rubio announced the cancellation of 83% of USAID programs, totaling approximately 5,200 contracts. Subsequently, we were notified that virtually all of our contracts with USAID were terminated for convenience with immediate effect. In fiscal 2025, our U.S. federal government revenue included $576.4 million from USAID programs compared to $677.2 million last fiscal year. We currently expect no significant USAID revenue in fiscal 2026. However, we do expect our U.S. federal revenue to grow next fiscal year, excluding USAID and disaster response activities.

In fiscal 2025, our U.S. state and local government revenue grew 28.8% compared to fiscal 2024 partially due to increased disaster response activity related to Hurricanes Helene and Milton. Excluding the disaster response work, our U.S. state and local government revenue increased 13.3% in fiscal 2025 compared to last fiscal year. This growth was due to continued investment by our clients in water infrastructure, including digital water automation. Most of our work for the U.S. state and local governments relates to critical water and environmental programs, which we expect to continue to grow in fiscal 2026.

Our U.S. commercial revenue declined 1.1% in fiscal 2025 primarily due to lower activity related to renewable energy, partially offset by increased environmental services compared to fiscal 2024. We expect our U.S. commercial revenue, excluding renewable energy, to grow in fiscal 2026.

(1) We believe that the presentation of "Revenue, net of subcontractor costs", which is a non-U.S. GAAP financial measure, enhances investors' ability to analyze our business trends and performance because it substantially measures the work performed by our employees. In the course of providing services, we routinely subcontract various services and, under certain international development programs, issue grants. Generally, these subcontractor costs and grants are passed through to our clients and, in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP") and industry practice, are included in our revenue when it is our contractual responsibility to procure or manage these activities. Because subcontractor services can vary significantly from project to project and period to period, changes in revenue may not necessarily be indicative of our business trends. Accordingly, we segregate subcontractor costs from revenue to promote a better understanding of our business by evaluating revenue exclusive of costs associated with external service providers.

NM = not meaningful

Our revenue growth in fiscal 2025 reflects increases in both our GSG and CIG reportable segments. For fiscal 2025, our GSG segment's revenue and revenue, net of subcontractor costs, increased $190.6 million, or 7.7%, and $219.8 million, or 11.5%, respectively, compared to last year. Our CIG segment's revenue increased $57.9 million, or 2.1%, and revenue, net of subcontractor costs, increased $75.7 million, or 3.1% in fiscal 2025 compared fiscal 2024. The fiscal 2025 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 fiscal 2025, our adjusted results exclude a non-cash goodwill impairment charge of $92.4 million related to our GDS reporting unit, which resulted from the aforementioned cancellation of USAID programs in the second quarter of fiscal 2025. This charge is further described in Note 6, "Goodwill and Intangible Assets" of the “Notes to Consolidated Financial Statements”. Additionally, for fiscal 2025, our adjusted results exclude a non-recurring charge of $115.0 million related to legal contingencies as described in Note 18, "Commitments and Contingencies" of the “Notes to Consolidated Financial Statements”. Our adjusted results also exclude adjustments to contingent consideration liabilities in fiscal 2025. Our fiscal 2024 adjusted results exclude acquisition and integration costs and adjustments to contingent consideration liabilities. We determined that there is no tax benefit in fiscal 2025 for $31.3 million of the legal contingency charge and $58.3 million of the goodwill impairment charge. The effective tax rate applied to the remaining adjustments in fiscal 2025 to arrive at the adjusted earnings per share ("EPS") was 24.6%. The effective tax rate applied to the adjustments to EPS to arrive at adjusted EPS in fiscal 2024 was 17%, which reflects certain integration costs/losses that were not tax deductible. 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.
