Notes to Consolidated Financial Statements
(unaudited)
1. Basis of Presentation
The accompanying consolidated financial statements of AECOM (the Company) are unaudited and, in the opinion of management, include all adjustments, including all normal recurring items necessary for a fair statement of the Company’s financial position and results of operations for the periods presented. All intercompany balances and transactions are eliminated in consolidation.
The consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Form 10-K for the fiscal year ended September 30, 2024 (the Annual Report). The accompanying unaudited consolidated financial statements and related notes have been prepared in accordance with generally accepted accounting principles (GAAP) in the United States (U.S.) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements.
The consolidated financial statements included in this report have been prepared consistently with the accounting policies described in the Annual Report, except as noted, and should be read together with the Annual Report.
The results of operations for the three and nine months ended June 30, 2025 are not necessarily indicative of the results to be expected for the fiscal year ending September 30, 2025.
As discussed in more detail in Note 3, the Company concluded that its self-perform at-risk construction businesses met the criteria for held for sale beginning in the first quarter of fiscal 2020 and met the criteria for discontinued operation classification. As a result, the self-perform at-risk construction businesses are presented in the consolidated statements of operations as discontinued operations for all periods presented. Current and non-current assets and liabilities of these businesses are presented in the consolidated balance sheets as assets and liabilities held for sale.
The Company reports its annual results of operations based on 52- or 53-week periods ending on the Friday nearest September 30. The interim consolidated financial statements are presented for the periods ending on June 27, 2025 and June 28, 2024. For clarity of presentation, all periods are presented as if the periods ended on September 30 and June 30.
2. New Accounting Pronouncements and Changes in Accounting
In November 2023, the Financial Accounting Standards Board (FASB) amended the guidance of Accounting Standards Codification (ASC) 280, Segment Reporting, requiring public entities to disclose significant segment expenses and other segment items on an interim basis. The new guidance is effective for the Company for its annual financial statements in fiscal year 2025 and for its interim financial statements in fiscal year 2026, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this new guidance will have on its financial statement presentation.
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which includes amendments that further enhance the income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid. The update also includes certain other amendments to improve the effectiveness of income tax disclosures. The amendments are effective for the Company’s annual periods beginning October 1, 2025, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this new guidance will have on its financial statement presentation.
In November 2024, the FASB issued ASU 2024-03 requiring public entities to provide disaggregated disclosures in the notes of the financial statements of certain categories of expenses that are included in expense line items on the face of the income statement on an interim basis. The new guidance is effective for the Company for its annual financial statements in fiscal year 2027 and for its interim financial statements in fiscal year 2028, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this new guidance will have on its financial statements.

3. Discontinued Operations, Goodwill and Intangible Assets
In the first quarter of fiscal 2020, management approved a plan to dispose of via sale the Company’s self-perform at-risk construction businesses. These businesses include the Company’s civil infrastructure, power, and oil and gas construction businesses that were previously reported in the Company’s Construction Services segment. After consideration of the relevant facts, the Company concluded the assets and liabilities of its self-perform at-risk construction businesses met the criteria for classification as held for sale. The Company concluded the actual and proposed disposal activities represented a strategic shift that would have a major effect on the Company’s operations and financial results and qualified for presentation as discontinued operations in accordance with FASB ASC 205-20. Accordingly, the financial results of the self-perform at-risk construction businesses are presented in the Consolidated Statement of Operations as discontinued operations for all periods presented. Current and non-current assets and liabilities of these businesses not sold as of the balance sheet date are presented in the Consolidated Balance Sheets as assets and liabilities held for sale for both periods presented.
The Company completed the sale of its power and oil and gas construction businesses in fiscal 2021 and fiscal 2022, respectively. The Company completed the sale of its civil infrastructure construction business to affiliates of Oroco Capital in the second quarter of fiscal 2021. In the second quarter of fiscal 2024, the Company recorded a $103.1 million loss related to a revised estimate of its contingent consideration receivable recognized in its civil infrastructure construction business.
During the third quarter of fiscal 2024, the Company resolved contingencies related to the sale of its civil infrastructure construction business and received equity in the counterparty, and the Company recorded a $12.7 million gain based on the fair value of the equity received. Concurrently, the Company participated as a member of a lending group in a revolving credit facility for the counterparty, committing to fund $30 million that matures in May 2029. At June 30, 2025, the counterparty had $4.4 million outstanding under the credit facility, and all cash flows were classified as other investing activities.
During the second quarter of fiscal 2025, the Company and its joint venture counterparty amended the joint venture agreement for a business classified as held for sale. In connection with the amendment and consistent with ASC 810, Consolidation, the Company reconsidered whether it remained the primary beneficiary under the variable interest model and concluded it was no longer the primary beneficiary. As such, the Company deconsolidated the joint venture as of the amendment date. The Company continues to present its retained noncontrolling interest as held for sale and equity in earnings from the joint venture are reported in net loss from discontinued operations. No gain or loss was recognized in the deconsolidation of the joint venture during the second quarter of fiscal 2025.
Department of Energy Deactivation, Demolition, and Removal Project
A former affiliate of the Company, Amentum Environment & Energy, Inc., f/k/a AECOM Energy and Construction, Inc. (“Former Affiliate”), executed a cost-reimbursable task order with the Department of Energy (DOE) in 2007 to provide deactivation, demolition and removal services at a New York State project site that, during 2010, experienced contamination and performance issues. In February 2011, the Former Affiliate and the DOE executed a Task Order Modification that changed some cost-reimbursable contract provisions to at-risk. The Task Order Modification, including subsequent amendments, required the DOE to pay all project costs up to $106 million, required the Former Affiliate and the DOE to equally share in all project costs incurred from $106 million to $146 million, and required the Former Affiliate to pay all project costs exceeding $146 million.
Due to unanticipated requirements and permitting delays by federal and state agencies, as well as delays and related ground stabilization activities caused by Hurricane Irene in 2011, the Former Affiliate was required to perform work outside the scope of the Task Order Modification. In December 2014, the Former Affiliate submitted an initial set of claims against the DOE pursuant to the Contracts Disputes Acts seeking recovery of $103 million, including additional fees on changed work scope (the “2014 Claims”). On December 6, 2019, the Former Affiliate submitted a second set of claims against the DOE seeking recovery of an additional $60.4 million, including additional project costs and delays outside the scope of the contract as a result of differing site and ground conditions (the “2019 Claims”). The Former Affiliate also submitted three alternative breach of contract claims to the 2014 Claims and the 2019 Claims that may entitle the Former Affiliate to recovery of $148.5 million to $329.4 million. On December 30, 2019, the DOE denied the Former Affiliate’s 2014 Claims. On September 25, 2020, the DOE denied the Former Affiliate’s 2019 Claims. The Company filed an appeal of these decisions on December 20, 2020 in the Court of Federal Claims. Deconstruction, decommissioning and site restoration activities are complete.

On January 31, 2020, the Company completed the sale of its Management Services business, including the Former Affiliate who worked on the DOE project, to Maverick Purchaser Sub LLC (“MS Purchaser”), an affiliate of American Securities LLC and Lindsay Goldberg LLC. The Company and the MS Purchaser agreed that all future DOE project claim recoveries and costs will be split 10% to the MS Purchaser and 90% to the Company with the Company retaining control of all future strategic legal decisions.
The Company intends to vigorously pursue all claimed amounts but can provide no certainty that the Company will recover 2014 Claims and 2019 Claims submitted against the DOE, or any additional incurred claims or costs, which could have a material adverse effect on the Company’s results of operations.
Refinery Turnaround Project
A former affiliate of the Company, which was sold in a series of transactions to effectuate the sale of the self‑perform at-risk construction businesses, entered into an agreement to perform turnaround maintenance services in Montana in December 2017. The former affiliate performed additional work outside of the original contract and became entitled to payment from the refinery owner. As part of the sale of the former affiliate, the refinery turnaround project, including related claims, were retained by the Company. The former affiliate's claims against the refinery owner and the refinery owner's crossclaims against the Company's former affiliate moved to federal court. A jury trial was completed on February 1, 2025, resulting in a favorable verdict for the Company. As a result of unfavorable court orders on post-trial motions during the third quarter of fiscal 2025, including pre-judgment interest and prompt payment interest, and issuance of the associated judgment, the Company recorded a $53.0 million loss from the reduction in the expected future net cash proceeds the Company would receive as a result of the trial verdict. The Company has appealed the judgment. The loss is reported in discontinued operations as the project was completed prior to the sale of the former affiliate.

4. Revenue Recognition
The Company follows accounting principles for recognizing revenue upon the transfer of control of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. The Company generally recognizes revenues over time as performance obligations are satisfied. The Company generally measures its progress to completion using an input measure of total costs incurred divided by total costs expected to be incurred, which it believes to be the best measure of progress towards completion of the performance obligation. In the course of providing its services, the Company routinely subcontracts for services and incurs other direct costs on behalf of its clients. These costs are passed through to clients and, in accordance with GAAP, are included in the Company’s revenue and cost of revenue. These pass-through revenues for the nine months ended June 30, 2025 and 2024 were $6.4 billion and $6.6 billion, respectively.
Recognition of revenue and profit is dependent upon a number of factors, including the accuracy of a variety of estimates made at the balance sheet date, such as engineering progress, material quantities, the achievement of milestones, penalty provisions, labor productivity and cost estimates. Additionally, the Company is required to make estimates for the amount of consideration to be received, including bonuses, awards, incentive fees, claims, unpriced change orders, penalties, and liquidated damages. Variable consideration is included in the estimate of the transaction price only to the extent that a significant reversal would not be probable. Management continuously monitors factors that may affect the quality of its estimates, and material changes in estimates are disclosed accordingly. Costs attributable to claims are treated as costs of contract performance as incurred.
The following summarizes the Company’s major contract types:
Cost Reimbursable Contracts
Cost reimbursable contracts include cost-plus fixed fee, cost-plus fixed rate, and time-and-materials price contracts. Under cost-plus contracts, the Company charges clients for its costs, including both direct and indirect costs, plus a negotiated fee or rate. The Company recognizes revenue based on actual direct costs incurred and the applicable fixed rate or portion of the fixed fee earned as of the balance sheet date. Under time-and-materials price contracts, the Company negotiates hourly billing rates and charges its clients based on the actual time that it expends on a project. In addition, clients reimburse the Company for materials and other direct incidental expenditures incurred in connection with its performance under the contract. The Company may apply a practical expedient to recognize revenue in the amount in which it has the right to invoice if its right to consideration is equal to the value of performance completed to date.
Guaranteed Maximum Price Contracts (GMP)
GMP contracts share many of the same contract provisions as cost-plus and fixed-price contracts. As with cost-plus contracts, clients are provided a disclosure of all the project costs, and a lump sum or percentage fee is separately identified. The Company provides clients with a guaranteed price for the overall project (adjusted for change orders issued by clients) and a schedule including the expected completion date. Cost overruns or costs associated with project delays in completion could be the Company’s responsibility. For many of the Company’s GMP contracts, the final price is generally not established until the Company has subcontracted a substantial percentage of the trade contracts with terms consistent with the master contract, and it has negotiated additional contractual limitations, such as waivers of consequential damages as well as aggregate caps on liabilities and liquidated damages. Revenue is recognized for GMP contracts as project costs are incurred relative to total estimated project costs.
11

Table of Contents
Fixed-Price Contracts
Fixed-price contracts include both lump-sum and fixed-unit price contracts. Under lump-sum contracts, the Company performs all the work under the contract for a specified fee. Lump-sum contracts are typically subject to price adjustments if the scope of the project changes or unforeseen conditions arise. Under fixed-unit price contracts, the Company performs a number of units of work at an agreed price per unit with the total payment under the contract determined by the actual number of units delivered. Revenue is recognized for fixed-price contracts using the input method measured on a cost-to-cost basis as the Company believes this is the best measure of progress towards completion.
Disaggregated Revenue
The following tables present the Company’s revenues disaggregated by revenue sources:

| Three Months Ended |  | Nine Months Ended |  |  |  |

Remaining Unsatisfied Performance Obligations
As of June 30, 2025, the Company had allocated $17.9 billion of transaction price to unsatisfied or partially satisfied performance obligations, of which approximately 59% is expected to be satisfied within the next twelve months. The majority of remaining performance obligation after the first 12 months are expected to be recognized over a two-year period.
Contract liabilities represent billings as of the balance sheet date, as allowed under the terms of a contract, but not yet recognized as contract revenue pursuant to the Company's revenue recognition policy. The Company recognized revenue of $859.9 million and $764.7 million during the nine months ended June 30, 2025 and 2024, respectively, that was included in contract liabilities as of September 30, 2024 and 2023, respectively.
The Company’s timing of revenue recognition may not be consistent with its rights to bill and collect cash from its clients. Those rights are generally dependent upon advance billing terms, milestone billings based on the completion of certain phases of work or when services are performed. The Company’s accounts receivables represent amounts billed to clients that have yet to be collected and represent an unconditional right to cash from its clients. Contract assets represent the amount of contract revenue recognized but not yet billed pursuant to contract terms or accounts billed after the balance sheet date.

Net accounts receivable consisted of the following:

| June 30, 2025 |  | September 30, 2024
| (in millions)
Billed | $ | 2,012.3 |  |  | $ | 2,184.9 |
Contract retentions | 674.1 |  |  | 696.3 |
Total accounts receivable—gross | 2,686.4 |  |  | 2,881.2 |
Allowance for doubtful accounts and credit losses | (88.7) |  |  | (87.9) |
Total accounts receivable—net | $ | 2,597.7 |  |  | $ | 2,793.3 |

Substantially all contract assets as of June 30, 2025 and September 30, 2024 are expected to be billed and collected within twelve months, except for claims. Significant claims recorded in contract assets and other non-current assets were approximately $320 million and $180 million as of June 30, 2025 and September 30, 2024, respectively. The asset related to the Deactivation, Demolition, and Removal Project retained from the MS Purchaser as defined in and discussed in Note 3 is presented in prepaid expense and other current assets from continuing operations in the Consolidated Balance Sheet. Contract retentions represent amounts invoiced to clients where payments have been withheld from progress payments until the contracted work has been completed and approved by the client but nonetheless represent an unconditional right to cash.
The Company considers a broad range of information to estimate expected credit losses including the related ages of past due balances, projections of credit losses based on historical trends, and collection history and credit quality of its clients. Negative macroeconomic trends or delays in payment of outstanding receivables could result in an increase in the estimated credit losses.
No single client accounted for more than 10% of the Company’s outstanding receivables at June 30, 2025 and September 30, 2024.
The Company sold trade receivables to financial institutions, of which $355.6 million and $319.5 million were outstanding as of June 30, 2025 and September 30, 2024, respectively. The Company does not retain financial or legal obligations for these receivables that would result in material losses. The Company’s ongoing involvement is limited to the remittance of customer payments to the financial institutions with respect to the sold trade receivables.
5. Joint Ventures and Variable Interest Entities
The Company’s joint ventures provide architecture, engineering, program management, construction management, operations and maintenance services, and invest in real estate projects. Joint ventures, the combination of two or more partners, are generally formed for a specific project. Management of the joint venture is typically controlled by a joint venture executive committee, comprised of representatives from the joint venture partners. The joint venture executive committee normally provides management oversight and controls decisions which could have a significant impact on the joint venture.
Some of the Company’s joint ventures have no employees and minimal operating expenses. For these joint ventures, the Company’s employees perform work for the joint venture, which is then billed to a third-party customer by the joint venture. These joint ventures function as pass-through entities to bill the third-party customer. For consolidated joint ventures of this type, the Company records the entire amount of the services performed and the costs associated with these services, including the services provided by the other joint venture partners, in the Company’s result of operations. For certain of these joint ventures where a fee is added by an unconsolidated joint venture to client billings, the Company’s portion of that fee is recorded in equity in earnings of joint ventures.
The Company also has joint ventures that have their own employees and operating expenses, and to which the Company generally makes a capital contribution. The Company accounts for these joint ventures either as consolidated entities or equity method investments based on the criteria further discussed below.
13

Table of Contents
The Company follows guidance on the consolidation of variable interest entities (VIEs) that requires companies to utilize a qualitative approach to determine whether it is the primary beneficiary of a VIE. The process for identifying the primary beneficiary of a VIE requires consideration of the factors that indicate a party has the power to direct the activities that most significantly impact the joint venture’s economic performance, including powers granted to the joint venture’s program manager, powers contained in the joint venture governing board and, to a certain extent, a company’s economic interest in the joint venture. The Company analyzes its joint ventures and classifies them as either:
•a VIE that must be consolidated because the Company is the primary beneficiary or the joint venture is not a VIE and the Company holds the majority voting interest with no significant participative rights available to the other partners; or
•a VIE that does not require consolidation and is treated as an equity method investment because the Company is not the primary beneficiary or the joint venture is not a VIE and the Company does not hold the majority voting interest.
As part of the above analysis, if it is determined that the Company has the power to direct the activities that most significantly impact the joint venture’s economic performance, the Company considers whether or not it has the obligation to absorb losses or rights to receive benefits of the VIE that could potentially be significant to the VIE.
Contractually required support provided to the Company’s joint ventures is further discussed in Note 15.

On April 19, 2024, the Company entered into Amendment No. 14 to Syndicated Facility Agreement (as amended, modified or otherwise supplemented, the "Credit Agreement"), pursuant to which the Company obtained a new $1,500,000,000 revolving credit facility (the “New Revolving Credit Facility”), a new $750,000,000 term loan A facility (the “New Term A Facility” and, together with the New Revolving Credit Facility, the “New Pro Rata Facilities”) and a new $700,000,000 term loan B facility (the “New Term B Facility” and, together with the New Pro Rata Facilities, the “New Credit Facilities”). The New Revolving Credit Facility and the New Term A Facility mature on April 19, 2029. The New Term B Facility matures on April 19, 2031. The New Term A Facility and the New Term B Facility were borrowed in full on April 19, 2024 in U.S. dollars. Loans under the New Revolving Credit Facility may be borrowed, and letters of credit thereunder may be issued, in U.S. dollars or in certain foreign currencies. The New Credit Facilities replace in full the Company's existing revolving credit facility, term loan A facility and term loan B facility, and borrowings under the New Credit Facilities were used to refinance in full the Company's existing credit facilities and for general corporate purposes. The Credit Agreement permits the Company to designate certain of its subsidiaries as additional co-borrowers from time to time. Currently, there are no co-borrowers under the New Credit Facilities. On October 29, 2024, the Company entered into Amendment No. 15 to Syndicated Facility Agreement, pursuant to which the Company reduced the interest rate spread applicable to its New Term B Facility.
Borrowings under (a) the New Revolving Credit Facility (in U.S. dollars) and the New Term A Facility bear interest at a rate per annum equal to, at the Company’s option, (i) a Term SOFR rate (with a 0% floor and SOFR adjustment of 0.10%) or (ii) a base rate (with a 0% floor), in each case, plus an applicable margin of 1.225% in the case of the Term SOFR rate and 0.225% in the case of the base rate, and (b) the New Revolving Credit Facility in currencies other than U.S. dollars bear interest at a rate per annum equal to the applicable reference rate for such currency (including any related adjustments), plus an applicable margin of 1.225%. The applicable margin is subject, in each case, to adjustment based on the Company’s consolidated leverage ratio from time to time.
Borrowings under the New Term B Facility, after giving effect to Amendment No. 15 to Syndicated Facility Agreement, bear interest at a rate per annum equal to, at the Company’s option, (a) a Term SOFR rate (with a 0% floor and a SOFR adjustment of 0%) or (b) a base rate (with a 0% floor), in each case, plus an applicable margin of 1.75% in the case of the Term SOFR rate and 0.75% in the case of the base rate.
Certain of the Company’s material subsidiaries (the “Guarantors”) have guaranteed the Company’s obligations of the borrowers under the Credit Agreement, subject to certain exceptions. The borrowers’ obligations under the Credit Agreement are secured by a lien on substantially all of the Company’s assets and its Guarantors’ assets, subject to certain exceptions.
The Credit Agreement contains customary negative covenants that include, among other things, limitations on the ability of the Company and certain of its subsidiaries, subject to certain exceptions, to incur liens and debt, make investments, dispositions, and restricted payments, change the nature of their business, consummate mergers, consolidations and the sale of all or substantially all of their respective assets and transact with affiliates. The Company is also required to maintain a consolidated leverage ratio of less than or equal to 4.00 to 1.00 (subject to certain adjustments in connection with permitted acquisitions), tested on a quarterly basis (the “Financial Covenant”). The Financial Covenant does not apply to the New Term B Facility. As of June 30, 2025, the Company was in compliance with the covenants of the Credit Agreement.
The Credit Agreement contains customary affirmative covenants, including, among other things, compliance with applicable law, preservation of existence, maintenance of properties and of insurance, and keeping proper books and records. The Credit Agreement contains customary events of default, including, among other things, nonpayment of principal, interest or fees, cross-defaults to other debt, inaccuracies of representations and warranties, failure to perform covenants, events of bankruptcy and insolvency, change of control and unsatisfied judgments, subject in certain cases to notice and cure periods and other exceptions.
At June 30, 2025 and September 30, 2024, letters of credit totaled $4.4 million and $4.4 million, respectively, under the Company’s New Revolving Credit Facility. As of June 30, 2025 and September 30, 2024, the Company had $1,495.6 million and $1,495.6 million, respectively, available under its New Revolving Credit Facility.
2027 Senior Notes
On February 21, 2017, the Company completed a private placement offering of $1,000,000,000 aggregate principal amount of its unsecured 5.125% Senior Notes due 2027 (the “2027 Senior Notes”). On June 30, 2017, the Company completed an exchange offer to exchange the unregistered 2027 Senior Notes for registered notes, as well as related guarantees.
17

Table of Contents
As of June 30, 2025, the estimated fair value of the 2027 Senior Notes was approximately $993.6 million. The fair value of the 2027 Senior Notes as of June 30, 2025 was derived by taking the mid-point of the trading prices from an observable market input (Level 2) in the secondary bond market and multiplying it by the outstanding balance of the 2027 Senior Notes. Interest was payable on the 2027 Senior Notes at a rate of 5.125% per annum. Interest on the 2027 Senior Notes was payable semi-annually on March 15 and September 15 of each year, commencing on September 15, 2017. The 2027 Senior Notes were set to mature on March 15, 2027.
At any time and from time to time prior to December 15, 2026, the Company may redeem all or part of the 2027 Senior Notes, at a redemption price equal to 100% of their principal amount, plus a “make whole” premium as of the redemption date, and accrued and unpaid interest to the redemption date.
The indenture pursuant to which the 2027 Senior Notes were issued contained customary events of default, including, among other things, payment default, exchange default, failure to provide notices thereunder and provisions related to bankruptcy events. The indenture also contained customary negative covenants.
The Company was in compliance with the covenants relating to the 2027 Senior Notes as of June 30, 2025.
Other Debt and Other Items
Other debt consists primarily of obligations under capital leases and loans, and unsecured credit facilities. The Company’s unsecured credit facilities are primarily used for standby letters of credit issued in connection with general and professional liability insurance programs and for contract performance guarantees. At June 30, 2025 and September 30, 2024, these outstanding standby letters of credit totaled $895.2 million and $934.5 million, respectively. As of June 30, 2025, the Company had $376.7 million available under these unsecured credit facilities.
Effective Interest Rate
The Company’s average effective interest rate on its total debt, including the effects of the interest rate swap and interest rate cap agreements, during the nine months ended June 30, 2025 and 2024 was 5.1% and 5.5%, respectively.
Interest expense in the consolidated statements of operations included amortization of deferred debt issuance costs for the three and nine months ended June 30, 2025 of $1.2 million and $3.9 million, respectively, and for the three and nine months ended June 30, 2024 of $4.0 million and $6.4 million, respectively.
Subsequent Events
2033 Senior Notes
On July 22, 2025, the Company completed an offering of $1,200,000,000 aggregate principal amount of its 6.000% Senior Notes due 2033 (the “2033 Senior Notes”).
Interest will be payable on the 2033 Senior Notes at a rate of 6.000% per annum. Interest on the 2033 Senior Notes will be payable semi-annually in arrears on February 1 and August 1 of each year, commencing on February 1, 2026. The 2033 Senior Notes will mature on August 1, 2033.

The purchase included a "make whole" payment of $6.4 million.
In addition, the Company also issued a redemption notice to noteholders to redeem on August 14, 2025 the remaining 2027 Senior Notes that are outstanding and not tendered in the tender offer. The redemption is expected to include a "make whole" payment of $2.3 million.
8. Derivative Financial Instruments and Fair Value Measurements
The Company uses interest rate derivative contracts to hedge interest rate exposures on the Company’s variable rate debt. The Company enters into foreign currency derivative contracts with financial institutions to reduce the risk that its cash flows and earnings will be adversely affected by foreign currency exchange rate fluctuations. The Company’s hedging program is not designated for trading or speculative purposes.
The Company recognizes derivative instruments as either assets or liabilities on the accompanying consolidated balance sheets at fair value. The Company records changes in the fair value (i.e., gains or losses) of the derivatives that have been designated as accounting hedges in the accompanying consolidated statements of operations as cost of revenue, interest expense or to accumulated other comprehensive loss in the accompanying consolidated balance sheets.
Cash Flow Hedges
The Company uses interest rate swap and interest rate cap agreements designated as cash flow hedges to limit exposure to variable interest rates on portions of the Company’s debt. The Company initially reports any gain on the effective portion of a cash flow hedge as a component of accumulated other comprehensive loss. Depending on the type of cash flow hedge, the gain is subsequently reclassified against interest expense when the interest expense on the variable rate debt is recognized. If the hedged transaction becomes probable of not occurring, any gain or loss related to interest rate swap or interest rate cap agreements would be recognized in other income.
The notional principal, fixed rates and related effective and expiration dates of the Company’s outstanding interest rate swap agreements were as follows:

June 30, 2025
Notional Amount Currency |  | Notional Amount (in millions) |  | Fixed Rate |  | Effective Date |  | Expiration Date
USD |  | 400.0 |  | 1.283% |  | February 2023 |  | March 2028

September 30, 2024
Notional Amount Currency |  | Notional Amount (in millions) |  | Fixed Rate |  | Effective Date |  | Expiration Date
USD |  | 400.0 |  | 1.283% |  | February 2023 |  | March 2028

In the fourth quarter of fiscal 2021, the Company entered into interest rate swap agreements with a notional value of $400.0 million to manage the interest rate exposure of its variable rate loans. The swaps became effective February 2023 and terminate in March 2028. By entering into the swap agreements, the Company converted a portion of the SOFR rate-based liability into a fixed rate liability. The Company will pay a fixed rate of 1.283% and receive payment at the prevailing one-month SOFR.
In the third quarter of fiscal 2022, the Company purchased interest rate cap agreements with a notional value of $300.0 million to manage interest rate exposure of its variable rate loans. The caps became effective on June 30, 2022 and terminate in March 2028. The caps reduce the Company’s exposure to one-month SOFR. In the event one-month SOFR exceeds 3.465%, the Company will receive the spread between prevailing one-month SOFR and 3.465%.

Table of Contents
See Note 14 for accumulated balances and reporting period activities of derivatives related to reclassifications out of accumulated other comprehensive loss for the nine months ended June 30, 2025 and 2024. Additionally, there were no material losses recognized in income due to amounts excluded from effectiveness testing from the Company’s interest rate swap agreements.
Other Foreign Currency Forward Contracts
The Company uses foreign currency forward contracts which are not designated as accounting hedges to hedge intercompany transactions and other monetary assets or liabilities denominated in currencies other than the functional currency of a subsidiary. Gains and losses on these contracts were not material for the nine months ended June 30, 2025 and 2024.
Fair Value Measurements
The fair values of the interest rate swap and interest rate cap agreements were derived by taking the net present value of the expected cash flows using observable market inputs (Level 2) such as SOFR rate curves, futures, volatilities and basis spreads (when applicable).
As discussed in Note 3, the Company received an equity investment in the civil infrastructure construction business buyer and concurrently participated as a member of a lending group in a revolving credit facility. The Company elected the fair value option for its equity investment due to the availability of quoted prices of identical assets. The fair value option was also elected for the credit facility investment. Changes in fair value of both investments are classified within other income on the consolidated statements of operations. The Company records interest income at the stated coupon rate of the credit facility and classifies it within interest income on the consolidated statement of operations. Fair value for the equity investment is determined using Level 1 inputs, and fair value of the credit facility investment is determined using Level 3 inputs, such as estimated cash flows and estimated discount rates. The Company recorded a loss of $6.9 million and $1.6 million in other income in the first nine months of fiscal 2025 and 2024, respectively, representing the decrease in fair value of these investments.
Below are the Company's non-pension financial assets and liabilities recorded at fair value on a recurring basis within the ASC 820-10 fair value hierarchy:

9. Share-based Payments
The Company grants stock units to employees under its Performance Earnings Program (PEP), whereby units are earned and issued dependent upon meeting established cumulative performance objectives and vest over a three-year service period. Additionally, the Company issues restricted stock units to employees and directors which are earned based on service conditions. The grant date fair value of PEP awards and restricted stock unit awards is primarily based on that day’s closing market price of the Company’s common stock.
Restricted stock units and PEP unit activity for the nine months ended June 30 was as follows:

Total compensation expense related to these share-based payments including stock options was $46.1 million and $44.8 million during the nine months ended June 30, 2025 and 2024, respectively. Unrecognized compensation expense related to total share-based payments outstanding as of June 30, 2025 and September 30, 2024 was $89.7 million and $68.7 million, respectively, to be recognized on a straight-line basis over the awards’ respective vesting periods which are generally three years.
10. Income Taxes
The Company’s effective tax rate was 20.6% and 23.6% for the nine months ended June 30, 2025 and 2024, respectively. The most significant items contributing to the difference between the statutory U.S. federal corporate tax rate of 21.0% and the Company’s effective tax rate for the nine-month period ended June 30, 2025 were a tax benefit of $47.2 million related to income tax credits and incentives, tax expense of $45.6 million related to foreign residual income, a tax benefit of $20.1 million related to deferred tax assets recognized due to legal entity restructuring, and tax expense of $19.6 million related to state income taxes. All these items, except for the deferred tax assets benefit, are expected to have a continuing impact on the effective tax rate for the remainder of the fiscal year.
The most significant items contributing to the difference between the statutory U.S. federal corporate tax rate of 21.0% and the Company’s effective tax rate for the nine-month period ended June 30, 2024 were a tax benefit of $46.1 million related to income tax credits and incentives, tax expense of $39.7 million related to foreign residual income, tax expense of $18.2 million related to state income taxes, a tax benefit of $8.4 million related to the exclusion of tax on non-controlling interests, tax expense of $7.4 million related to changes in valuation allowances, a tax benefit of $6.9 million related to an audit settlement, and tax expense of $5.6 million related to nondeductible costs.
During the first quarter of fiscal 2025, the Company recognized deferred tax assets of $20.1 million related to legal entity restructuring. The restructuring resulted in the recognition of deferred tax assets related to tax attributes that are expected to be utilized against future taxable income.

Table of Contents
During the first quarter of fiscal 2024, the Company settled its tax audit in Hong Kong for fiscal year 2011 through fiscal year 2021 and recorded a tax benefit of $6.9 million due primarily to changes in uncertain tax positions.
The Company is utilizing the annual effective tax rate method under ASC 740 to compute its interim tax provision. The Company’s effective tax rate fluctuates from quarter to quarter due to various factors including the change in the mix of global income and expenses, outcomes of administrative audits, changes in the assessment of valuation allowances due to management’s consideration of new positive or negative evidence during the quarter, and changes in enacted tax laws. The U.S. and many international legislative and regulatory bodies have proposed legislation that could significantly impact how our business activities are taxed. These proposed changes could have a material impact on the Company’s income tax expense and deferred tax balances.
The Company is currently under tax audit in several jurisdictions including the U.S. where its federal income tax returns for fiscal 2017 through 2020 are being examined by the IRS. Disputes can arise with tax authorities involving issues related to the timing of deductions, the calculation and use of credits, and the taxation of income in various tax jurisdictions because of differing interpretations or application of tax laws, regulations, and relevant facts. The IRS is currently auditing certain tax credits and the methodology for calculating the credits. While the Company has historically been able to sustain the credits in previous audit cycles without adjustment, the Company believes it’s reasonably possible there could be an adjustment to the liability for uncertain tax positions within the next twelve months related to this issue. However, the Company is not able to reasonably estimate the range of potential outcomes.
Generally, the Company does not provide for U.S. taxes or foreign withholding taxes on gross book-tax differences in its non-U.S. subsidiaries because such basis differences of approximately $1.2 billion are able to and intended to be reinvested indefinitely. If these basis differences were distributed, foreign tax credits could become available under current law to partially or fully reduce the resulting U.S. income tax liability. There may also be additional U.S. or foreign income tax liability upon repatriation, although the calculation of such additional taxes is not practicable.
11. Earnings Per Share
Basic earnings per share (EPS) excludes dilution and is computed by dividing net income attributable to AECOM by the weighted average number of common shares outstanding for the period. Diluted EPS is computed by dividing net income attributable to AECOM by the weighted average number of common shares outstanding and potential common shares for the period. The Company includes as potential common shares the weighted average dilutive effects of equity awards using the treasury stock method. For the three and nine months ended June 30, 2025 and 2024, equity awards excluded from the calculation of potential common shares were not significant.
The following table sets forth a reconciliation of the denominators for basic and diluted earnings per share:

| Three Months Ended |  | Nine Months Ended
| June 30, 2025 |  | June 30, 2024 |  | June 30, 2025 |  | June 30, 2024
| (in millions)
Denominator for basic earnings per share | 132.3 |  | 136.0 |  | 132.4 |  | 136.0
Potential common shares | 0.8 |  | 0.8 |  | 0.9 |  | 0.9
Denominator for diluted earnings per share | 133.1 |  | 136.8 |  | 133.3 |  | 136.9

12. Leases
The Company and its subsidiaries are lessees in non-cancelable leasing agreements for office buildings and equipment. Substantially all of the Company’s office building leases are operating leases, and its equipment leases are both operating and finance leases. The Company groups lease and non-lease components for its equipment leases into a single lease component but separates lease and non-lease components for its office building leases.
The Company recognizes a right-of-use asset and lease liability for its operating leases at the commencement date equal to the present value of the contractual minimum lease payments over the lease term. The present value is calculated using the rate implicit in the lease, if known, or the Company’s incremental secured borrowing rate. The discount rate used for operating leases is primarily determined based on an analysis of the Company’s incremental secured borrowing rate, while the discount rate used for finance leases is primarily determined by the rate specified in the lease.

Table of Contents
The related lease payments are expensed on a straight-line basis over the lease term, including, as applicable, any free-rent period during which the Company has the right to use the asset. For leases with renewal options where the renewal is reasonably assured, the lease term, including the renewal period, is used to determine the appropriate lease classification and to compute periodic rental expense. Leases with initial terms shorter than 12 months are not recognized on the balance sheet, and lease expense is recognized on a straight-line basis.
The components of lease expenses are as follows:

| Three Months Ended |  | Nine Months Ended

15. Commitments and Contingencies
The Company records amounts representing its probable estimated liabilities relating to claims, guarantees, litigation, audits and investigations. The Company relies in part on qualified actuaries to assist it in determining the level of reserves to establish for insurance-related claims that are known and have been asserted against it, and for insurance-related claims that are believed to have been incurred based on actuarial analysis, but have not yet been reported to the Company’s claims administrators as of the respective balance sheet dates. The Company includes any adjustments to such insurance reserves in its consolidated results of operations. The Company’s reasonably possible loss disclosures are presented on a gross basis prior to the consideration of insurance recoveries. The Company does not record gain contingencies until they are realized. In the ordinary course of business, the Company may not be aware that it or its affiliates are under investigation and may not be aware of whether or not a known investigation has been concluded.
In the ordinary course of business, the Company may enter into various arrangements providing financial or performance assurance to clients, lenders, or partners. Such arrangements include standby letters of credit, surety bonds, and corporate guarantees to support the creditworthiness or the project execution commitments of its affiliates, partnerships and joint ventures. The Company’s unsecured credit arrangements are used for standby letters of credit issued in connection with general and professional liability insurance programs and for contract performance guarantees. At June 30, 2025 and September 30, 2024, these outstanding standby letters of credit totaled $895.2 million and $934.5 million, respectively. As of June 30, 2025, the Company had $376.7 million available under these unsecured credit facilities. Performance arrangements typically have various expiration dates ranging from the completion of the project contract and extending beyond contract completion in some circumstances such as for warranties. The Company may also guarantee that a project, when complete, will achieve specified performance standards. If the project subsequently fails to meet guaranteed performance standards, the Company may incur additional costs, pay liquidated damages or be held responsible for the costs incurred by the client to achieve the required performance standards. The potential payment amount of an outstanding performance arrangement is typically the remaining cost of work to be performed by or on behalf of third parties. Generally, under joint venture arrangements, if a partner is financially unable to complete its share of the contract, the other partner(s) may be required to complete those activities.
At June 30, 2025, the Company was contingently liable in the amount of approximately $899.6 million in issued standby letters of credit and $4.9 billion in issued surety bonds primarily to support project execution.
In the ordinary course of business, the Company enters into various agreements providing financial or performance assurances to clients on behalf of certain unconsolidated partnerships, joint ventures and other jointly executed contracts. These agreements are entered into primarily to support the project execution commitments of these entities.
The Company’s investment adviser jointly manages and sponsors the AECOM-Canyon Equity Fund, L.P. (the “Fund”), in which the Company indirectly holds an equity interest and has an ongoing capital commitment to fund investments. At June 30, 2025, the Company has capital commitments of $5.1 million to the Fund over the next 4 years.
In addition, in connection with the investment activities of AECOM Capital, the Company provides guarantees of certain contractual obligations, including guarantees for completion of projects, limited debt repayment, environmental indemnity obligations and other lender required guarantees.
In February 2024, the Company was informed of a potential liability as one of the indemnitors on a divested business’ surety bonds. The Company does not have sufficient information to determine the range of potential impacts; however, it is reasonably possible that the Company may incur additional costs related to these bonds.
In connection with the resolution of contingencies related to the sale of the civil infrastructure construction business, the Company agreed to act as an additional guarantor on the counterparty’s existing debt, which was extended to March 2028.

16. Reportable Segments
The Company manages its operations under three reportable segments according to their geographic regions and business activities. In identifying its reportable segments, the Company considered the financial information provided to its chief operating decision maker (CODM), who is the chief executive officer. The financial data is organized by geographic region and global business lines. The CODM uses this information to allocate resources and assess the performance of the segments primarily based on revenue less pass-through revenue and attributable earnings before interest, tax, and amortization expense. After considering various factors, including the development and utilization of financial data to the CODM, the Company concluded that identifying its operating segments by geography was consistent with the objectives of ASC 280-10. Certain operating segments have been aggregated based on similar characteristics, including long-term financial performance, the nature of services provided, internal process for delivering those services, and types of customers, to arrive at the Company’s reportable segments. The Company’s Americas reportable segment provides planning, consulting, architectural and engineering design services, and construction management services to public and private clients in the United States, Canada, and Latin America and is comprised of the Design and Consulting Services Americas and Construction Management operating segments. The Company’s International reportable segment provides similar professional services to public and private clients in Europe and India, the Middle East and Africa, Asia, and Australia and New Zealand and is comprised of the operating segments in those geographic regions. The Company’s AECOM Capital (ACAP) operating segment is its own reportable segment and primarily invests in and develops real estate projects. Certain expenses that are determined to be related to the Company as a whole are not deemed to be part of an operating segment but are reported within Corporate.

Overview
We are a leading global provider of professional infrastructure consulting and advisory services for governments, businesses and organizations throughout the world. We provide advisory, planning, consulting, architectural and engineering design, construction and program management services, and investment and development services to public and private clients worldwide in major end markets such as transportation, facilities, water, environmental, and energy.
Our business focuses primarily on providing fee-based knowledge-based services. We primarily derive income from our ability to generate revenue and collect cash from our clients through the billing of our employees’ time spent on client projects and our ability to manage our costs. AECOM Capital primarily derives its income from real estate development sales and management fees.
29

Table of Contents
We report our continuing business through three segments, each of which is described in further detail below: Americas, International, and AECOM Capital (ACAP). Such segments are organized by the differing specialized needs of the respective clients and how we manage the business. We have aggregated various operating segments into our reportable segments based on their similar characteristics, including similar long-term financial performance, the nature of services provided, internal processes for delivering those services, and types of customers.
•Americas: Planning, advisory, consulting, architectural and engineering design, construction management and program management services to public and private clients in the United States, Canada, and Latin America in major end markets such as transportation, water, government, facilities, environmental, and energy.
•International: Planning, advisory, consulting, architectural and engineering design services, site supervision and program management to public and private clients in Europe, the Middle East, India, Africa and the Asia-Australia-Pacific regions in major end markets such as transportation, water, government, facilities, environmental, and energy.
•AECOM Capital (ACAP): Primarily invests in and develops real estate projects.
Our revenue is dependent on our ability to attract and retain qualified and productive employees, identify business opportunities, allocate our labor resources and capital to profitable and high growth markets, secure new contracts, and renew existing client agreements. Demand for our services may be vulnerable to sudden economic downturns and reductions in government and private industry spending, which may result in clients delaying, curtailing or canceling proposed and existing projects. Moreover, as a professional services company, maintaining the high quality of the work generated by our employees is integral to our revenue generation and profitability. Given the global nature of our business, our revenue is exposed to currency rate fluctuations that could change from period to period and year to year.
Our costs consist primarily of the compensation we pay to our employees, including salaries, fringe benefits, the costs of hiring subcontractors, other project-related expenses and sales, general and administrative costs.
At June 30, 2025, we had approximately $894.5 million remaining of the Board’s stock repurchase authorization. On November 14, 2024, the Board approved an increase in our stock repurchase authorization to $1.0 billion. We intend to deploy future available cash towards dividends and stock repurchases consistent with our returns driven capital allocation policy.
We have exited substantially all of our self-perform at-risk construction businesses. As part of our ongoing plan to improve profitability and maintain a reduced risk profile, we continuously evaluate our business portfolio.
We completed a transaction that transitioned the AECOM Capital team to a new third-party platform in the third quarter of fiscal 2024. The team will continue to support AECOM Capital’s investment vehicles pursuant to certain advisory agreements in a manner consistent with their current obligations.

Revenue
Our revenue for the three months ended June 30, 2025 increased $27.2 million, or 0.7%, to $4,178.4 million as compared to $4,151.2 million for the corresponding period last year.
Our revenue for the nine months ended June 30, 2025 decreased $30.8 million, or 0.3%, to $11,964.2 million as compared to $11,995.0 million for the corresponding period last year.
The Company's portion of revenue excluding pass-through revenue attributable to subcontractors increased for both the three- and nine-month periods ending June 30, 2025. Underlying revenue excluding pass-through revenues increased across most of our end markets as a result of increased investment by large, publicly financed, global infrastructure programs including the Infrastructure Investment and Jobs Act in the U.S. and similar large programs in our largest end markets globally. Our Water end market has been benefiting from increased investment to address drought, flooding, emerging contaminant remediation, water storage, and clean and safe drinking water. Our Transportation end market has been benefiting from incremental investments across the globe to modernize transportation infrastructure and address growth and urbanization trends, while our Environment end market has been benefiting from infrastructure that requires permitting, compliance, and remediation as well as investments in energy. Our Facilities end market has been benefiting from positive public sector investment, trends in asset maintenance and repositioning as well as demand for modern, efficient facilities. The quantification of the impact of these trends by end market is noted within our Americas and International reportable segments discussion below, where applicable, and represents substantially all of our revenue change.

Table of Contents
In the course of providing our services, we routinely subcontract for services and incur other direct costs on behalf of our clients. These costs are passed through to clients and, in accordance with industry practice and GAAP, are included in our revenue and cost of revenue. Because these pass-through revenues can change significantly from project to project and period to period, changes in revenue may not be indicative of business trends. Pass-through revenues for the quarters ended June 30, 2025 and 2024 were $2.2 billion and $2.3 billion, respectively. Pass-through revenue as a percentage of total revenue was 54% and 56% during the three months ended June 30, 2025 and 2024, respectively. Pass-through revenues for the nine months ended June 30, 2025 and 2024 were $6.4 billion and $6.6 billion, respectively. Pass-through revenue as a percentage of total revenue was 53% and 55% during the nine months ended June 30, 2025 and 2024, respectively.
Cost of Revenue
Our cost of revenue decreased to $3,851.5 million for the three months ended June 30, 2025 compared to $3,866.1 million for the corresponding period last year, a decrease of $14.6 million, or 0.4%.
Our cost of revenue decreased to $11,078.1 million for the nine months ended June 30, 2025 compared to $11,204.8 million for the corresponding period last year, a decrease of $126.7 million, or 1.1%.
Substantially all of the change in our cost of revenue for the three and nine months ended June 30, 2025 occurred in our Americas and International reportable segments, which is discussed in more detail below.
Gross Profit
Our gross profit for the three months ended June 30, 2025 increased $41.8 million, or 14.7%, to $326.9 million as compared to $285.1 million for the corresponding period last year. For the three months ended June 30, 2025, gross profit, as a percentage of revenue, increased to 7.8% from 6.9% in the corresponding period last year.
Our gross profit for the nine months ended June 30, 2025 increased $95.9 million, or 12.1%, to $886.1 million as compared to $790.2 million for the corresponding period last year. For the nine months ended June 30, 2025, gross profit, as a percentage of revenue, increased to 7.4% from 6.6% in the corresponding period last year.
Gross profit changes were due to the reasons noted in our Americas and International reportable segments below.
Equity in Earnings of Joint Ventures
Our equity in earnings of joint ventures for the three months ended June 30, 2025 was $5.3 million as compared to $7.7 million in the corresponding period last year.
Our equity in earnings of joint ventures for the nine months ended June 30, 2025 was $21.7 million as compared to equity in losses of $1.8 million in the corresponding period last year.
The decrease in equity in earnings of joint ventures for the three months ended June 30, 2025 compared to the same period in the prior year was primarily due to decreases in the Americas and Asia compared to the prior year. The increase in equity in earnings of joint ventures for the nine months ended June 30, 2025 compared to the same period in the prior year was primarily due to impairment losses recorded by our AECOM Capital segment in the first half of fiscal 2024 that did not repeat in fiscal 2025.
General and Administrative Expenses
Our general and administrative expenses for the three months ended June 30, 2025 increased $2.0 million, or 5.5%, to $38.2 million as compared to $36.2 million for the corresponding period last year. For the three months ended June 30, 2025, general and administrative expenses, as a percentage of revenue, remained the same at 0.9% from the corresponding period last year.
Our general and administrative expenses for the nine months ended June 30, 2025 increased $2.1 million, or 1.8%, to $118.7 million as compared to $116.6 million for the corresponding period last year. For the nine months ended June 30, 2025, general and administrative expenses, as a percentage of revenue, remained the same at 1.0% from the corresponding period last year.
The increase in general and administrative expenses for the three and nine months ended June 30, 2025 was primarily due to increased investments in expanding our advisory and digital capabilities.

Restructuring Costs
Restructuring costs are comprised of personnel costs, real estate costs, and costs associated with business exits. No new transformative restructuring actions were initiated during the three and nine months ended June 30, 2025. During the three and nine months ended June 30, 2024, we incurred total restructuring costs of $29.1 million and $80.7 million, respectively, primarily related to costs incurred to continue to align our real estate portfolio with our employee flexibility initiatives, continue our exit of certain countries in Southeast Asia, drive support function efficiency, and reduce our risk profile.
Other Income (Loss)
Our other income for the three months ended June 30, 2025 was $0.8 million compared to $1.0 million for the corresponding period last year.
Our other loss for the nine months ended June 30, 2025 was $1.0 million compared to other income of $6.2 million for the corresponding period last year.
The decreases in other income for the three and nine months ended June 30, 2025 were primarily due to the decrease in fair value of our investments measured at fair value.
Interest Income
Our interest income for the three months ended June 30, 2025 decreased to $14.1 million from $15.8 million for the corresponding period last year.
Our interest income for the nine months ended June 30, 2025 increased to $45.2 million from $43.3 million for the corresponding period last year.
The increase in interest income for the nine months ended June 30, 2025 was primarily due to an increase in our interest-bearing assets.
Interest Expense
Our interest expense for the three months ended June 30, 2025 was $40.1 million as compared to $51.4 million for the corresponding period last year.
Our interest expense for the nine months ended June 30, 2025 was $125.4 million as compared to $140.4 million for the corresponding period last year.
The decreases in interest expense for the three and nine months ended June 30, 2025 were primarily due to a decrease in our interest-bearing liabilities as well as additional financing charges recorded in the three months ended June 30, 2024 related to the New Credit Facilities, defined below, that did not repeat in the current year.
Income Tax Expense
Our income tax expense for the three months ended June 30, 2025 was $65.1 million as compared to $46.1 million in the corresponding period last year. The increase in tax expense for the current period compared to the corresponding period last year was due primarily to the tax impact of an increase in pre-tax income of $75.9 million and tax expense of $5.5 million related to return to provision adjustments resulting from the filing of the prior year's tax return.
Our income tax expense for the nine months ended June 30, 2025 was $145.6 million as compared to $118.1 million in the corresponding period last year. The increase in tax expense for the current period compared to the corresponding period last year was due primarily to the tax impact of an increase in pre-tax income of $207.7 million, a tax benefit of $20.1 million related to deferred tax assets recognized due to legal entity restructuring implemented in the first quarter of fiscal 2025, an increase in tax benefit of $10.2 million related to changes in valuation allowances, a tax benefit of $6.9 million related to an audit settlement in the first quarter of fiscal 2024 that did not repeat in fiscal 2025, and tax expense of $5.5 million related to return to provision adjustments resulting from the filing of the prior year's tax return.
During the first quarter of fiscal 2025, we recognized deferred tax assets of $20.1 million related to legal entity restructuring. The restructuring resulted in the recognition of deferred tax assets related to tax attributes that are expected to be utilized against future taxable income.

During the first quarter of fiscal 2024, we settled our tax audit in Hong Kong for fiscal year 2011 through fiscal year 2021 and recorded a tax benefit of $6.9 million due primarily to changes in uncertain tax positions.
On July 4, 2025, the U.S. government enacted the One Big Beautiful Bill Act (the “Tax Act”), which permanently extends many provisions of the Tax Cuts and Jobs Act of 2017 and introduces new tax provisions relevant for multinational businesses. Most of the new provisions take effect starting in fiscal 2026. We’re currently evaluating the potential impact of this legislation on our consolidated financial statements, but based on our preliminary assessment, we do not expect the legislation to have a material impact.
Net Loss From Discontinued Operations
During the first quarter of fiscal 2020, management approved a plan to dispose of via sale our self-perform at-risk construction businesses. As a result of these strategic actions, the self-perform at-risk construction businesses were classified as discontinued operations.
Net loss from discontinued operations was $43.9 million for the three months ended June 30, 2025 compared to net income of $5.7 million for the three months ended June 30, 2024, a decrease of $49.6 million.
Net loss from discontinued operations was $63.8 million for the nine months ended June 30, 2025 and was $105.0 million for the nine months ended June 30, 2024, a decrease of $41.2 million.
The increase in net loss from discontinued operations for the three months ended June 30, 2025 was primarily due to a revision to estimated recoveries of $53.0 million on a refinery turn around project resulting from unfavorable court orders on post-trial motions during the third quarter of fiscal 2025. The decrease in net loss from discontinued operations for the nine months ended June 30, 2025 was primarily due to the settlement of contingent consideration related to the sale of our civil infrastructure construction business in 2024 that did not recur in 2025.
Net Income Attributable to AECOM
The factors described above resulted in net income attributable to AECOM of $131.0 million and $441.4 million for the three and nine months ended June 30, 2025 as compared to net income attributable to AECOM of $134.3 million and $229.7 million for the three and nine months ended June 30, 2024.

Gross profit for our International segment for the three months ended June 30, 2025 increased $6.9 million, or 8.5%, to $88.0 million as compared to $81.1 million for the corresponding period last year. As a percentage of revenue, gross profit increased to 9.8% of revenue for the three months ended June 30, 2025 from 9.0% in the corresponding period last year.
Gross profit for our International segment for the nine months ended June 30, 2025 increased $14.1 million, or 6.1%, to $244.2 million as compared to $230.1 million for the corresponding period last year. As a percentage of revenue, gross profit increased to 9.1% of revenue for the nine months ended June 30, 2025 from 8.6% in the corresponding period last year.
The increases in gross profit and gross profit as a percentage of revenue for the three and nine months ended June 30, 2025 were primarily due to benefits from restructuring actions taken last year, ongoing exits from lower margin countries, growth in the enterprise capability centers, and continuous improvement initiatives.

Equity in earnings of joint ventures for the three months ended June 30, 2025 increased $0.3 million, or 42.9%, to $1.0 million compared to $0.7 million for the corresponding period last year. The increase in equity in earnings of joint ventures for the three months ended June 30, 2025 was primarily due to favorable earnings of an investment in the current year compared to the prior year. Equity in earnings of joint ventures for the nine months ended June 30, 2025 increased $26.6 million, or 100.4%, to $0.1 million compared to a loss of $26.5 million for the corresponding period last year. The change in equity in losses of joint ventures for the nine months ended June 30, 2025 was primarily due to impairment losses of $35.9 million recognized in fiscal 2024 that did not repeat in fiscal 2025.
Seasonality
We experience seasonal trends in our business. Our revenue is typically higher in the last half of the fiscal year. The fourth quarter of our fiscal year (July 1 to September 30) is typically our strongest quarter. We find that the U.S. federal government tends to authorize more work during the period preceding the end of our fiscal year, September 30. In addition, many U.S. state governments with fiscal years ending on June 30 tend to accelerate spending during their first quarter, when new funding becomes available. Further, our construction management revenue typically increases during the summer months when weather and daylight hours are more conducive to outdoor activities. Within the United States, as well as other parts of the world, our business generally benefits from milder weather conditions in our fiscal fourth quarter. Our construction and project management services also typically expand during the summer months when weather and daylight hours are more conducive to outdoor activities. The first quarter of our fiscal year (October 1 to December 31) is typically our lowest revenue quarter. The harsher weather conditions impact our ability to complete work in parts of North America and the holiday season schedule affects our productivity during this period. For these reasons, coupled with the number and significance of client contracts commenced and completed during a particular period, as well as the timing of expenses incurred for corporate initiatives, it is not unusual for us to experience seasonal changes or fluctuations in our quarterly operating results.
Liquidity and Capital Resources
Cash Flows
Our principal sources of liquidity are cash flows from operations, borrowings under our credit facilities, and access to financial markets. Our principal uses of cash are operating expenses, capital expenditures, working capital requirements, acquisitions, repurchases of common stock, dividend payments, and refinancing or repayment of debt. We believe our anticipated sources of liquidity including operating cash flows, existing cash and cash equivalents, borrowing capacity under our revolving credit facility and our ability to issue debt or equity, if required, will be sufficient to meet our projected cash requirements for at least the next twelve months. We expect to spend approximately $45 million for restructuring costs in fiscal 2025 associated with restructuring actions taken in prior periods that are expected to deliver continued margin improvement and efficiencies.
Generally, we do not provide for U.S. taxes or foreign withholding taxes on gross book-tax basis differences in our non-U.S. subsidiaries because such basis differences are able to and intended to be reinvested indefinitely. At June 30, 2025, we have determined that we will continue to indefinitely reinvest the earnings of some foreign subsidiaries and, therefore, we will continue to account for these undistributed earnings based on our existing accounting under ASC 740 and not accrue additional tax. Determination of the amount of any unrecognized deferred income tax liability on this temporary difference is not practicable because of the complexities of the hypothetical calculation. Based on the available sources of cash flows discussed above, we anticipate we will continue to have the ability to permanently reinvest these remaining amounts.

At June 30, 2025, cash and cash equivalents were $1,794.1 million, an increase of $209.2 million from $1,584.9 million at September 30, 2024, which included cash and cash equivalents included in current assets held for sale.
Net cash provided by operating activities was $625.5 million for the nine months ended June 30, 2025 as compared to $528.7 million for the nine months ended June 30, 2024. The change was primarily attributable to an increase in net income of approximately $221.3 million, partially offset by cash used by changes in working capital of $52.9 million, and a decrease in adjustments for non-cash items of approximately $71.7 million. The sale of trade receivables to financial institutions included in operating cash flows increased $60.1 million during the nine months ended June 30, 2025 compared to the nine months ended June 30, 2024. We expect to continue to sell trade receivables in the future as long as the terms continue to remain favorable to us.
Net cash used in investing activities was $133.3 million for the nine months ended June 30, 2025, as compared to $185.9 million for the nine months ended June 30, 2024. The change was primarily attributable to cash repayments of $16.6 million on the revolving credit facility from the counterparty to our sale of our civil infrastructure construction business, a $17.9 million decrease in investments in unconsolidated joint ventures and a decrease in cash payments for capital expenditures of approximately $20.6 million, partially offset by cash outflow from the deconsolidation of a discontinued operation of $45.4 million.
Net cash used in financing activities was $281.6 million for the nine months ended June 30, 2025 as compared to net cash provided by financing activities of $44.4 million for the nine months ended June 30, 2024. The change from the prior year was primarily attributable to $320.1 million in net cash proceeds pursuant to Amendment No. 14 of the Credit Agreement that occurred in the third quarter of fiscal 2024. Total borrowings under our Credit Agreement may vary during the period as we regularly draw and repay amounts to fund working capital.
Working Capital
Working capital, or current assets less current liabilities, increased $237.1 million, or 29.6%, to $1,039.1 million at June 30, 2025 from $802.0 million at September 30, 2024. Net accounts receivable and contract assets, net of contract liabilities, decreased to $3,355.0 million at June 30, 2025 from $3,301.4 million at September 30, 2024.
Days Sales Outstanding (DSO), which includes net accounts receivable and contract assets, net of contract liabilities, was 72 days at June 30, 2025 compared to 70 days at September 30, 2024.
In Note 4, Revenue Recognition, in the notes to our consolidated financial statements, a comparative analysis of the various components of accounts receivable is provided. Except for claims, substantially all contract assets are expected to be billed and collected within twelve months.
Contract assets related to claims are recorded only if it is probable that the claim will result in additional contract revenue and if the amount can be reliably estimated. In such cases, revenue is recorded only to the extent that contract costs relating to the claim have been incurred. Award fees in contract assets are accrued only when there is sufficient information to assess contract performance. On contracts that represent higher than normal risk or technical difficulty, award fees are generally deferred until an award fee letter is received.
Because our revenue depends to a great extent on billable labor hours, most of our charges are invoiced following the end of the month in which the hours were worked, the majority usually within 15 days. Other direct costs are normally billed along with labor hours. However, as opposed to salary costs, which are generally paid on either a bi-weekly or monthly basis, other direct costs are generally not paid until payment is received (in some cases in the form of advances) from the customers.

Credit Agreement
On April 19, 2024, we entered into Amendment No. 14 to Syndicated Facility Agreement (as amended, modified or otherwise supplemented, the "Credit Agreement"), pursuant to which we obtained a new $1,500,000,000 revolving credit facility (the “New Revolving Credit Facility”), a new $$750,000,000 term loan A facility (the “New Term A Facility” and, together with the New Revolving Credit Facility, the “New Pro Rata Facilities”) and a new $700,000,000 term loan B facility (the “New Term B Facility” and, together with the New Pro Rata Facilities, the “New Credit Facilities”). The New Revolving Credit Facility and the New Term A Facility mature on April 19, 2029. The New Term B Facility matures on April 19, 2031. The New Term A Facility and the New Term B Facility were borrowed in full on April 19, 2024 in U.S. dollars. Loans under the New Revolving Credit Facility may be borrowed, and letters of credit thereunder may be issued, in U.S. dollars or in certain foreign currencies. The New Credit Facilities replace in full our existing revolving credit facility, term loan A facility and term loan B facility, and borrowings under the New Credit Facilities were used to refinance in full our existing credit facilities and for general corporate purposes. The Credit Agreement permits us to designate certain of our subsidiaries as additional co-borrowers from time to time. Currently, there are no co-borrowers under the New Credit Facilities. On October 29, 2024, we entered into Amendment No. 15 to Syndicated Facility Agreement, pursuant to which we reduced the interest rate spread applicable to our New Term B Facility.
Borrowings under (a) the New Revolving Credit Facility (in U.S. dollars) and the New Term A Facility bear interest at a rate per annum equal to, at our option, (i) a Term SOFR rate (with a 0% floor and SOFR adjustment of 0.10%) or (ii) a base rate (with a 0% floor), in each case, plus an applicable margin of 1.225% in the case of the Term SOFR rate and 0.225% in the case of the base rate, and (b) the New Revolving Credit Facility in currencies other than U.S. dollars bear interest at a rate per annum equal to the applicable reference rate for such currency (including any related adjustments), plus an applicable margin of 1.225%. The applicable margin is subject, in each case, to adjustment based on our consolidated leverage ratio from time to time.
Borrowings under the New Term B Facility, after giving effect to Amendment No. 15 to Syndicated Facility Agreement, bear interest at a rate per annum equal to, at our option, (a) a Term SOFR rate (with a 0% floor and a SOFR adjustment of 0%) or (b) a base rate (with a 0% floor), in each case, plus an applicable margin of 1.75% in the case of the Term SOFR rate and 0.75% in the case of the base rate.

Certain of our material subsidiaries (the “Guarantors”) have guaranteed our obligations of the borrowers under the Credit Agreement, subject to certain exceptions. The borrowers’ obligations under the Credit Agreement are secured by a lien on substantially all of our assets and the Guarantors’ assets, subject to certain exceptions.
The Credit Agreement contains customary negative covenants that include, among other things, limitations on our ability and certain of our subsidiaries, subject to certain exceptions, to incur liens and debt, make investments, dispositions, and restricted payments, change the nature of our business, consummate mergers, consolidations and the sale of all or substantially all of our respective assets and transact with affiliates. We are also required to maintain a consolidated leverage ratio of less than or equal to 4.00 to 1.00 (subject to certain adjustments in connection with permitted acquisitions), tested on a quarterly basis (the “Financial Covenant”). The Financial Covenant does not apply to the New Term B Facility. As of June 30, 2025, we were in compliance with the covenants of the Credit Agreement.
The Credit Agreement contains customary affirmative covenants, including, among other things, compliance with applicable law, preservation of existence, maintenance of properties and of insurance, and keeping proper books and records. The Credit Agreement contains customary events of default, including, among other things, nonpayment of principal, interest or fees, cross-defaults to other debt, inaccuracies of representations and warranties, failure to perform covenants, events of bankruptcy and insolvency, change of control and unsatisfied judgments, subject in certain cases to notice and cure periods and other exceptions.
At June 30, 2025 and September 30, 2024, letters of credit totaled $4.4 million and $4.4 million, respectively, under our New Revolving Credit Facility. As of June 30, 2025 and September 30, 2024, we had $1,495.6 million and $1,495.6 million, respectively, available under our New Revolving Credit Facility.
2027 Senior Notes
On February 21, 2017, we completed a private placement offering of $1,000,000,000 aggregate principal amount of our unsecured 5.125% Senior Notes due 2027 (the “2027 Senior Notes”). On June 30, 2017, we completed an exchange offer to exchange the unregistered 2027 Senior Notes for registered notes, as well as related guarantees.
As of June 30, 2025, the estimated fair value of the 2027 Senior Notes was approximately $993.6 million. The fair value of the 2027 Senior Notes as of June 30, 2025 was derived by taking the mid-point of the trading prices from an observable market input (Level 2) in the secondary bond market and multiplying it by the outstanding balance of the 2027 Senior Notes. Interest was payable on the 2027 Senior Notes at a rate of 5.125% per annum. Interest on the 2027 Senior Notes was payable semi-annually on March 15 and September 15 of each year, commencing on September 15, 2017. The 2027 Senior Notes were set to mature on March 15, 2027.
At any time and from time to time prior to December 15, 2026, we may redeem all or part of the 2027 Senior Notes, at a redemption price equal to 100% of their principal amount, plus a “make whole” premium as of the redemption date, and accrued and unpaid interest to the redemption date.
The indenture pursuant to which the 2027 Senior Notes were issued contained customary events of default, including, among other things, payment default, exchange default, failure to provide notices thereunder and provisions related to bankruptcy events. The indenture also contained customary negative covenants.
We were in compliance with the covenants relating to the 2027 Senior Notes as of June 30, 2025.
On July 22, 2025, we used a portion of the net proceeds of the offering of the 2033 Senior Notes (defined below) to purchase $732,914,000 in principal amount of the 2027 Senior Notes that were validly tendered and not validly withdrawn at or prior to the July 21, 2025 expiration date of its previously announced tender offer for the 2027 Senior Notes. The purchase included a make-whole payment of $6.4 million.
In addition, we also issued a redemption notice to noteholders to redeem on August 14, 2025 the remaining 2027 Senior Notes that are outstanding and not tendered in the tender offer. The redemption is expected to include a make-whole payment of $2.3 million.
2033 Senior Notes
On July 22, 2025, we completed an offering of $1,200,000,000 aggregate principal amount of our 6.000% Senior Notes due 2033 (the “2033 Senior Notes”).

Table of Contents
Interest will be payable on the 2033 Senior Notes at a rate of 6.000% per annum. Interest on the 2033 Senior Notes will be payable semi-annually in arrears on February 1 and August 1 of each year, commencing on February 1, 2026. The 2033 Senior Notes will mature on August 1, 2033.
Prior to August 1, 2028, we may redeem all or part of the 2033 Senior Notes at a redemption price equal to 100% of the principal amount to be redeemed, plus a “make whole” premium as of the redemption date, and accrued and unpaid interest to, but excluding, the redemption date. In addition, prior to August 1, 2028, we may redeem up to 40% of the aggregate principal amount of the 2033 Senior Notes with proceeds from certain equity offerings at a redemption price equal to 106% of the principal amount to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. Furthermore, at any time on or after August 1, 2028, we may redeem on one or more occasions all or part of the 2033 Senior Notes at the redemption prices set forth below, plus accrued and unpaid interest thereon to, but excluding, the redemption date, if redeemed during the 12-month period beginning on August 1 of each of the years indicated below:
Percentage
2028 ................................................................................................................... 103.000%
2029 ................................................................................................................... 101.500%
2030 and thereafter ................................................................................................ 100.000%
The indenture pursuant to which the 2033 Senior Notes were issued contains customary events of default, including, among other things, payment default, failure to provide certain notices thereunder and certain provisions related to bankruptcy events. The indenture also contains customary negative covenants.
Other Debt and Other Items
Other debt consists primarily of obligations under capital leases and loans, and unsecured credit facilities. The unsecured credit facilities are primarily used for standby letters of credit issued in connection with general and professional liability insurance programs and for contract performance guarantees. At June 30, 2025 and September 30, 2024, these outstanding standby letters of credit totaled $895.2 million and $934.5 million, respectively. As of June 30, 2025, we had $376.7 million available under these unsecured credit facilities.
Effective Interest Rate
Our average effective interest rate on our total debt, including the effects of the interest rate swap agreements and interest rate cap agreements during the nine months ended June 30, 2025 and 2024 was 5.1% and 5.5%, respectively.
Interest expense in the consolidated statements of operations included amortization of deferred debt issuance costs for the three and nine months ended June 30, 2025 of $1.2 million and $3.9 million, respectively, and for the three and nine months ended June 30, 2024 of $4.0 million and $6.4 million, respectively.
Other Commitments
We enter into various joint venture arrangements to provide architectural, engineering, program management, construction management and operations and maintenance services. The ownership percentage of these joint ventures is typically representative of the work to be performed or the amount of risk assumed by each joint venture partner. Some of these joint ventures are considered variable interest entities. We have consolidated all joint ventures for which we have control. For all others, our portion of the earnings is recorded in equity in earnings of joint ventures. See Note 5, Joint Ventures and Variable Interest Entities, in the notes to our consolidated financial statements.
Other than normal property and equipment additions and replacements, expenditures to further the implementation of our various information technology systems, commitments under our incentive compensation programs, amounts we may expend to repurchase stock under our stock repurchase program and acquisitions from time to time and disposition costs, we currently do not have any significant capital expenditures or outlays planned except as described below. However, if we acquire additional businesses in the future or if we embark on other capital-intensive initiatives, additional working capital may be required.
Under our secured revolving credit facility and other facilities discussed in Other Debt and Other Items above, as of June 30, 2025, there was approximately $899.6 million, including both continuing and discontinued operations, outstanding under standby letters of credit primarily issued in connection with general and professional liability insurance programs and for contract performance guarantees. For those projects for which we have issued a performance guarantee, if the project subsequently fails to meet guaranteed performance standards, we may either incur significant additional costs or be held responsible for the costs incurred by the client to achieve the required performance standards.

Table of Contents
We recognized on our balance sheet the funded status of our pension benefit plans, measured as the difference between the fair value of plan assets and the projected benefit obligation. At June 30, 2025, our defined benefit pension plans had an aggregate deficit (the excess of projected benefit obligations over the fair value of plan assets) of approximately $102.5 million. The total amounts of employer contributions paid for the nine months ended June 30, 2025 were $7.7 million for U.S. plans and $17.2 million for non-U.S. plans. Funding requirements for each plan are determined based on the local laws of the country where such plan resides. In some countries, the funding requirements are mandatory while in other countries, they are discretionary. There is a required minimum contribution for one of our domestic plans; however, we may make additional discretionary contributions. In the future, such pension funding may increase or decrease depending on changes in the levels of interest rates, pension plan performance and other factors. In addition, we have collective bargaining agreements with unions that require us to contribute to various third-party multiemployer plans that we do not control or manage. For the year ended September 30, 2024, we contributed $2.5 million to multiemployer pension plans.
Contractual Obligations
Refer to our Annual Report on Form 10-K for the year ended September 30, 2024 for a discussion of our contractual obligations. There have been no changes, outside of the ordinary course of business, to these contractual obligations during the nine months ended June 30, 2025.
Condensed Combined Financial Information
The 2027 Senior Notes are fully and unconditionally guaranteed on a joint and several basis by some of AECOM’s directly and indirectly 100% owned subsidiaries (the Subsidiary Guarantors). Accordingly, AECOM became subject to the requirements of Rule 3-10 of Regulation S-X, as amended, regarding financial statements of guarantors and issuers of guaranteed securities. Other than customary restrictions imposed by applicable statutes, there are no restrictions on the ability of the Subsidiary Guarantors to transfer funds to AECOM in the form of cash dividends, loans or advances.
The following tables present condensed combined summarized financial information for AECOM and the Subsidiary Guarantors. All intercompany balances and transactions are eliminated in the presentation of the combined financial statements. Amounts provided do not represent our total consolidated amounts as of June 30, 2025 and September 30, 2024, and for the nine months ended June 30, 2025.

New Accounting Pronouncements and Changes in Accounting
For information regarding recent accounting pronouncements, see Notes to Consolidated Financial Statements included in Part I, Item 1.
Critical Accounting Estimates
Our accounting policies often require management to make significant estimates and assumptions using information available at the time the estimates are made. Such estimates and assumptions significantly affect various reported amounts of assets, liabilities, revenues and expenses. If future experience differs significantly from these estimates and assumptions, our results of operations and financial condition could be affected.
The Notes to Consolidated Financial Statements in Part II, Item 8 of the Company’s Annual Report on Form 10-K for the year ended September 30, 2024 (the “2024 Form 10-K”), and “Critical Accounting Estimates” in Part II, Item 7 of the 2024 Form 10-K describe the significant accounting policies and estimates used in the preparation of our consolidated financial statements. We have not materially changed our estimation methodology since the 2024 Form 10-K.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
Financial Market Risks
Financial Market Risks
We are exposed to market risk, primarily related to foreign currency exchange rates and interest rate exposure of our debt obligations that bear interest based on floating rates. We actively monitor these exposures. Our objective is to reduce, where we deem appropriate to do so, fluctuations in earnings and cash flows associated with changes in foreign exchange rates and interest rates. In order to accomplish this objective, we sometimes enter into derivative financial instruments, such as forward contracts and interest rate hedge contracts. It is our policy and practice to use derivative financial instruments only to the extent necessary to manage our exposures. We do not use derivative financial instruments for trading purposes.
Foreign Exchange Rates
We are exposed to foreign currency exchange rate risk resulting from our operations outside of the U.S. We use foreign currency forward contracts from time to time to mitigate foreign currency risk. We limit exposure to foreign currency fluctuations in most of our contracts through provisions that require client payments in currencies corresponding to the currency in which costs are incurred. As a result of this natural hedge, we generally do not need to hedge foreign currency cash flows for contract work performed. The functional currency of our significant foreign operations is the respective local currency.

Table of Contents
Interest Rates
Our Credit Agreement and other debt obligations are subject to variable rate interest which could be adversely affected by an increase in interest rates. As of June 30, 2025 and September 30, 2024, we had $1,441.6 million and $1,446.6 million, respectively, in outstanding borrowings under our term credit agreements and revolving credit facility. Interest on amounts borrowed under these agreements is subject to adjustment based on specified levels of financial performance. The applicable margin that is added to the borrowing’s base rate can range from 0.125% to 1.00% and the applicable margin that is added to borrowings in the Term SOFR rate can range from 1.125% to 2.00%. For the nine months ended June 30, 2025, our weighted average floating rate borrowings were $1,635.6 million, or $935.6 million excluding borrowings with effective fixed interest rates due to interest rate swap and interest rate cap agreements. If short-term floating interest rates had increased by 1.00%, our interest expense for the nine months ended June 30, 2025 would have increased by $7.0 million. We invest our cash in a variety of financial instruments, consisting principally of money market securities or other highly liquid, short-term securities that are subject to minimal credit and market risk.
Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures

PART II. OTHER INFORMATION
Item 1. Legal Proceedings
As a government contractor, we are subject to various laws and regulations that are more restrictive than those applicable to non-government contractors. Intense government scrutiny of contractors’ compliance with those laws and regulations through audits and investigations is inherent in government contracting; and from time to time, we receive inquiries, subpoenas, and similar demands related to our ongoing business with government entities. Violations can result in civil or criminal liability as well as suspension or debarment from eligibility for awards of new government contracts or option renewals.
We are involved in various investigations, claims and lawsuits in the normal conduct of our business. We are not always aware if we or our affiliates are under investigation or the status of such matters. Although the outcome of our legal proceedings cannot be predicted with certainty and no assurances can be provided, in the opinion of our management, based upon current information and discussions with counsel, with the exception of the matters noted in Note 15, Commitments and Contingencies, to the financial statements contained in this report to the extent stated therein, none of the investigations, claims and lawsuits in which we are involved is expected to have a material adverse effect on our consolidated financial position, results of operations, cash flows or our ability to conduct business. See Note 15, Commitments and Contingencies, to the financial statements contained in this report for a discussion of certain matters to which we are a party. The information set forth in such note is incorporated by reference into this Item 1. From time to time, we establish reserves for litigation when we consider it probable that a loss will occur.
