(“SpinCo”) (the “Separation”), (ii) Jacobs then effectuated a spin-off of SpinCo by distributing 124,084,108 shares of SpinCo common stock, par value $0.01 per share (the “SpinCo Common Stock”) by way of a pro rata distribution to its shareholders such that each holder of shares of Jacobs common stock, par value $1.00 per share, (the “Jacobs Common Stock”) was entitled to receive one share of SpinCo Common Stock for each share of Jacobs Common Stock held as of the record date, September 23, 2024 (the “Distribution”), and (iii) finally, Amentum Parent Holdings LLC merged with and into SpinCo, with SpinCo surviving the merger (the “Merger” and together with the Separation and the Distribution, the “Separation Transaction”).
As a result of the Separation, substantially all SpinCo Business-related assets and liabilities have been separated and distributed (the "Disposal Group"). The Company determined that the Disposal Group should be reported as discontinued operations in accordance with ASC 205-20, Discontinued Operations because their disposal represents a strategic shift that had a major effect on the Company's operations and financial results. As such, the financial results of the SpinCo Business are reflected in the Company's Consolidated Statements of Earnings as well as relevant disclosures as discontinued operations for all periods presented. See Note 15- Discontinued Operations for more information.

Use of Estimates and Assumptions Use of Estimates and Assumptions
The preparation of financial statements in conformity with U.S. GAAP requires us to employ estimates and make assumptions that affect the reported amounts of certain assets and liabilities; the revenues and expenses reported for the periods covered by the financial statements; and certain amounts disclosed in these Notes to the Consolidated Financial Statements. Although such estimates and assumptions are based on management’s most recent assessment of the underlying facts and circumstances utilizing the most current information available and past experience, actual results
could differ significantly from those estimates and assumptions. Our estimates, judgments and assumptions are evaluated periodically and adjusted accordingly.
Please refer to Note 2- Significant Accounting Policies of Notes to Consolidated Financial Statements included in our 2024 Form 10-K for a discussion of other significant estimates and assumptions affecting our consolidated financial statements.

Fair Value Disclosures [Abstract]  
Fair Value and Fair Value Measurements Fair Value and Fair Value Measurements
Certain amounts included in the accompanying consolidated financial statements are presented at fair value. Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants as of the date fair value is determined (the “measurement date”). When determining fair value, we consider the principal or most advantageous market in which we would transact, and we consider only those assumptions we believe a typical market participant would consider when pricing an asset or liability. In measuring fair value, we use the following inputs in the order of priority indicated:
Level 1 - Quoted prices in active markets for identical assets or liabilities.
Level 2 - Observable inputs other than quoted prices in active markets included in Level 1, such as (i) quoted prices for similar assets or liabilities; (ii) quoted prices in markets that have insufficient volume or infrequent transactions (e.g., less active markets); and (iii) model-driven valuations in which all significant inputs are observable or can be derived principally from, or corroborated with, observable market data for substantially the full term of the asset or liability.
Level 3 - Unobservable inputs to the valuation methodology that are significant to the fair value measurement.
Please refer to Note 2- Significant Accounting Policies of Notes to Consolidated Financial Statements included in our 2024 Form 10-K for a more complete discussion of the various items within the consolidated financial statements measured at fair value and the methods used to determine fair value. Please also refer to Note 18- Commitments and Contingencies and Derivative Financial Instruments for discussion regarding the Company's derivative instruments and Note 15- Discontinued Operations for discussion regarding the Company's investment in Amentum common shares.
The net carrying amounts of cash and cash equivalents, trade receivables and payables and short-term debt approximate fair value due to the short-term nature of these instruments. See Note 12- Borrowings for a discussion of the fair value of long-term debt.

Our revenues are principally derived from contracts to provide a diverse range of technical, professional, and construction services to a large number of industrial, commercial, and governmental clients. We provide a broad range of engineering, design, and architectural services; construction and construction management services; operations and maintenance services; and technical, digital, process, scientific and systems consulting services. We provide our services through offices and subsidiaries located primarily in North America, Europe, the Middle East, India, Australia, Africa, and Asia. We provide our services under cost-reimbursable and fixed-price contracts. Our contracts are with many different customers in numerous industries. Refer to Note 19- Segment Information for additional information on how we disaggregate our revenues by reportable segment.
The following table further disaggregates our revenue by geographic area for the three and nine months ended June 27, 2025 and June 28, 2024 (in thousands):

Revenue recognized for the three and nine months ended June 28, 2024 that was included in the contract liability balance on September 29, 2023 was $49.6 million and $487.0 million, respectively.
Remaining Performance Obligations
The Company’s remaining performance obligations as of June 27, 2025 represent a measure of the total dollar value of work to be performed on contracts awarded and in progress. The Company had approximately $15.2 billion in remaining performance obligations as of June 27, 2025. The Company expects to recognize approximately 51% of its remaining performance obligations into revenue within the next twelve months and the remaining 49% thereafter. The majority of the remaining performance obligations after the first twelve months are expected to be recognized over a four-year period.
Although our remaining performance obligations reflect business volumes that are considered to be firm, normal business activities including scope adjustments, deferrals or cancellations may occur that impact volume or expected timing of their recognition. Remaining performance obligations are adjusted to reflect any known project cancellations, revisions to project scope and cost, foreign currency exchange fluctuations and project deferrals, as appropriate.

Earnings Per Share Reconciliation [Abstract]  
Earnings Per Share and Certain Related Information Earnings Per Share and Certain Related Information
Basic and diluted earnings per share (“EPS”) are computed using the two-class method, which is an earnings allocation method that determines EPS for common shares and participating securities. The undistributed earnings are allocated between common shares and participating securities as if all earnings had been distributed during the period. Participating securities and common shares have equal rights to undistributed earnings. Net earnings used for the purpose of determining basic and diluted EPS is determined by taking net earnings, less earnings available to participating securities and the preferred redeemable noncontrolling interests redemption value adjustment associated with the PA Consulting transaction.
The following table reconciles the denominator used to compute basic EPS to the denominator used to compute diluted EPS for the three and nine months ended June 27, 2025 and June 28, 2024 (in thousands):

Share Repurchases
On January 16, 2020, the Company's Board of Directors authorized a share repurchase program of up to $1.0 billion of the Company's common stock (the "2020 Repurchase Authorization"). The 2020 Repurchase Authorization expired on January 15, 2023. On January 25, 2023, the Company's Board of Directors authorized an incremental share repurchase program of up to $1.0 billion of the Company's common stock, to expire on January 25, 2026 (the "2023 Repurchase Authorization"). During the second fiscal quarter of 2025, the Company repurchased the remaining amount of common stock authorized under the 2023 Repurchase Authorization.
On January 30, 2025, the Company's Board of Directors authorized an incremental share repurchase program of up to $1.5 billion of the Company's common stock, to expire on January 30, 2028 (the "2025 Repurchase Authorization"). At June 27, 2025, the Company had $1.3 billion remaining under the 2025 Repurchase Authorization.
The following table summarizes repurchase activity for fiscal 2025 under the 2023 Repurchase Authorization through the third fiscal quarter of 2025:

The authorization for the share repurchase programs may be terminated, increased or decreased by the Company’s Board of Directors in its discretion at any time. The timing, amount and manner of share repurchases may depend upon market conditions and economic circumstances, availability of investment opportunities, the availability and costs of financing, currency fluctuations, the market price of the Company's common stock, other uses of capital and other factors.

Income Taxes Income Taxes
The Company’s effective tax rates from continuing operations for the three months ended June 27, 2025 and June 28, 2024 were 21.9% and 33.2%, respectively. Significant items contributing to differences between the statutory U.S. federal corporate tax rate of 21.0% and the Company's effective tax rate for the three-month period ended June 27, 2025 were U.S. state income tax expense and U.S. tax on foreign earnings. These expense items were offset by a return-to-provision income tax benefit, mainly attributable to additional research and development credits claimed on the U.S. federal tax return. The U.S state income tax and U.S. tax on foreign earnings are expected to have a continuing impact on the Company's 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 of 33.2% for the three-month period ended June 28, 2024 were related to U.S. state income tax expense, U.S. tax on foreign earnings and income tax expense related to foreign exchange gains associated with change in assertion on intercompany loans that were previously indefinitely reinvested. These expense items were partly offset by a return-to-provision income tax benefit, mainly attributable to additional research and development credits claimed on the U.S. federal tax return.
The Company’s effective tax rates from continuing operations for the nine months ended June 27, 2025 and June 28, 2024 were 45.6% and 14.9%, 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 27, 2025 were related to $63.1 million in unfavorable tax impacts associated with the non-deductibility of losses from the Company's investment in Amentum stock, as well as U.S. state income tax expense and U.S. tax on foreign earnings. These expense items were partly offset by a return-to-provision income tax benefit mainly attributable to additional research and development credits claimed on the U.S. federal tax return. The U.S state income tax and U.S. tax on foreign earnings are expected to have a continuing impact on the Company's effective tax rate for the remainder of the fiscal year.
The most significant item contributing to the difference between the statutory U.S. federal corporate tax rate of 21.0% and the Company's effective tax rate of 14.9% for the nine-month period ended June 28, 2024 were related to the election to treat an Australian subsidiary as a corporation versus a partnership for U.S. tax purposes, which resulted in the derecognition of a deferred tax liability and yielded a discrete income tax benefit of $61.6 million as the Company asserted that a component of the investment will be indefinitely reinvested. This benefit was partly offset by U.S. state income tax expense, U.S. tax on foreign earnings and income tax related to foreign exchange gains associated with change in assertion on intercompany loans that were previously indefinitely reinvested.
On July 4, 2025, H.R. 1, also referred to as the “One Big Beautiful Bill Act” (“OBBBA”), was enacted in the U.S. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act (“TCJA”), modifications to the international tax framework and pre-TCJA treatment for certain business provisions. ASC 740, Income Taxes, requires the effects of changes in tax rates and laws on deferred tax balances to be recognized in the period in which the legislation is enacted. The OBBBA has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The Company is currently assessing its impact on the consolidated financial statements which will be recorded during the fourth quarter of fiscal 2025.
In December 2021, the Organization for Economic Cooperation and Development ("OECD") released the Pillar Two Model Rules (also referred to as the global minimum tax or Global Anti-Base Erosion "GloBE" rules), which were designed to ensure large multinational enterprises pay a minimum 15 percent level of tax on the income arising in each jurisdiction in which they operate. Several jurisdictions in which we operate have enacted these rules, which were effective for the first quarter of the fiscal year ending September 26, 2025. The Company is continually monitoring developments and evaluating the potential impacts. At this time, implementation of these rules has not generated a material impact on consolidated income taxes.
The amount of income taxes the Company pays is subject to ongoing audits by tax jurisdictions around the world. In the normal course of business, the Company is subject to examination by tax authorities throughout the world, including such major jurisdictions as Australia, Canada, India, the United Kingdom and the United States. Our estimate of the potential outcome of any uncertain tax issue is subject to our assessment of the relevant risks, facts, and circumstances existing at the time. The Company believes that it has adequately provided for reasonably foreseeable outcomes related to these matters. However, future results may include favorable or unfavorable adjustments to our estimated tax liabilities in the period the assessments are made or resolved, which may impact our effective tax rate.

(1)The U.S. dollar denominated borrowings under the Revolving Credit Facility bear interest at either a SOFR rate plus a margin of between 0.975% and 1.725% or a base rate plus a margin of between 0% and 0.625% depending on the Company’s Consolidated Leverage Ratio or Debt Rating (each as defined in the Revolving Credit Facility (defined below)). The interest rate under the Revolving Credit Agreement also incorporates a modest sustainability-linked pricing adjustment, which resulted in a favorable interest rate adjustment to the Company in February 2025. The applicable SOFR rates, including applicable margins, at June 27, 2025 and September 27, 2024 were approximately 5.49% and 6.64%. Borrowings denominated in British pounds bear interest at an adjusted SONIA rate plus a margin of between 0.908% and 1.658%. There were no amounts drawn in British pounds as of June 27, 2025.
(2)The U.S. dollar denominated borrowings under the 2021 Term Loan Facility bear interest at either a SOFR rate plus a margin of between 0.975% and 1.725% or a base rate plus a margin of between 0% and 0.625% depending on the Company’s Consolidated Leverage Ratio or Debt Rating (each as defined in the Amended and Restated Term Loan Agreement (defined below)). The applicable SOFR rate, including applicable margins, for borrowings denominated in U.S. dollars at September 27, 2024 was approximately 6.52%. Borrowings denominated in British pounds bear interest at an adjusted SONIA rate plus a margin of between 0.908% and 1.658%, which was approximately 6.23% at September 27, 2024.
(3)Borrowings under the 2025 Term Loan Facility will bear interest at either a SONIA rate or term SOFR rate plus a margin of between 0.975% and 1.60% or a base rate plus a margin of between 0% and 0.50% depending on the Company’s Consolidated Leverage Ratio. The applicable SOFR and SONIA rates, including applicable margins, at June 27, 2025 were approximately 5.43% for borrowings denominated in U.S. dollars and 5.22% for borrowings denominated in British pounds.
(4)The interest rate payable on the 5.90% Bonds (as defined below) may be increased by an additional 12.5 basis points on each of September 1, 2028 and September 1, 2030, based on whether or not the Company achieves the key performance indicators set forth in the First Supplemental Indenture (as defined below). Each key performance indicator is independent of the other. Therefore, we may achieve one, both, or neither.
(5)Balance as of September 27, 2024 is associated with the September 1, 2025 scheduled maturity of the 2021 Term Loan Facility, which was reclassified from long-term debt in September 2024 and subsequently extinguished before March 28, 2025.
We believe the carrying values of the Revolving Credit Facility and the 2025 Term Loan Facility approximates fair value based on the interest rates and scheduled maturities applicable to the outstanding borrowings. At June 27, 2025, the fair value of the 5.90% Bonds and the 6.35% bonds is estimated to be $516.3 million and $627.3 million, respectively, based on Level 2 inputs. The fair value is determined by discounting future cash flows using interest rates available for issuances with similar terms and average maturities.
Revolving Credit Facility and Term Loans
The Company and certain of its subsidiaries maintain an unsecured revolving credit facility (the “Revolving Credit Facility”) established under a third amended and restated credit agreement, dated February 6, 2023 (the "Revolving Credit Agreement"), among Jacobs and certain of its subsidiaries as borrowers and a syndicate of U.S. and international banks and financial institutions. Amounts up to $2.25 billion in credit extensions under the Revolving Credit Facility can be funded in U.S. dollars, British Sterling, Euros, Canadian dollars, Australian dollars, Swedish Krona, Singapore dollars and other agreed upon alternative currencies. The Revolving Credit Agreement also provides for a financial letter of credit sub facility of $400.0 million, permits performance letters of credit, and provides for a $100.0 million sub facility for swing line loans. Letters of credit are subject to fees based on the Company’s Consolidated Leverage Ratio and Debt Rating, whichever is more favorable to the Company. The maturity date of the Revolving Credit Facility is February 6, 2028. The Company is a guarantor of the obligations of JEGI and its subsidiaries under the Revolving Credit Agreement.
The Company and JEGI maintained an unsecured delayed draft term loan facility (the “2021 Term Loan Facility”) established under an amended and restated term loan agreement dated February 6, 2023 (the "Amended and Restated Term Loan Agreement"), by and among the Company and JEGI and a syndicate of banks and financial institutions. JEGI borrowed $200.0 million and £650.0 million of term loans under the 2021 Term Loan Facility (reflecting scheduled maturities in February 2026 and September 2025, respectively) and the proceeds of such term loans were used primarily to fund JEGI's investment in PA Consulting.
On March 13, 2025, the Company exchanged approximately 19.5 million shares of our investment in Amentum Holdings, Inc. for approximately £239.8 million, or $311.5 million, in aggregate principal amount under the 2021 Term Loan Facility in an equity-for-debt transaction (the "Equity-for-Debt Transaction"). The aggregate principal amount of debt was immediately extinguished, and the Company received no other consideration (cash or otherwise) in connection with the exchange. For more information, please refer to Note 15 - Discontinued Operations. In connection with the Equity-for-Debt Transaction, $20.5 million in discounts and expenses were recognized as loss on extinguishment of debt.
On March 27, 2025, the Company, as guarantor, and JEGI, as borrower, entered into a term loan agreement (the “2025 Term Loan Facility”) with Bank of America, N.A., as administrative agent and sole lead arranger, and the lenders party thereto. Under the 2025 Term Loan Facility, JEGI borrowed a $200.0 million term loan and £410.0 million term loan for a term of two-years from the date of initial funding, maturing on March 26, 2027. The proceeds from the 2025 Term Loan Facility were used to repay the remaining outstanding 2021 Term Loan Facility principal equal to $120.0 million and £410.2 million, or $531.6 million, with the remaining proceeds used for general corporate purposes.
We were in compliance with the covenants under the Revolving Credit Facility and 2025 Term Loan Facility at June 27, 2025.

On February 16, 2023, JEGI completed an offering of $500.0 million aggregate principal amount of 5.90% Bonds due 2033 (the “5.90% Bonds”).

The 6.35% Bonds and the 6.35% Bonds Guarantee were offered pursuant to a prospectus supplement, dated August 15, 2023, to the prospectus dated February 6, 2023, that forms a part of the Company and JEGI’s automatic shelf registration statement on Form S-3ASR previously filed with the SEC, and were issued pursuant to the Indenture, as amended and supplemented by the Second Supplemental Indenture, dated as of August 18, 2023 (the “Second Supplemental Indenture”).

Separation of Critical Mission Solutions (“CMS”) and Cyber & Intelligence (“C&I”) Businesses
On September 27, 2024, Jacobs completed the previously announced Reverse Morris Trust transaction pursuant to which (i) Jacobs first transferred its CMS and portions of its DVS business to Amazon Holdco Inc., a Delaware corporation ("SpinCo"), which has since been renamed Amentum Holdings, Inc., (ii) Jacobs then effectuated a spin-off of SpinCo by distributing 124,084,108 shares of SpinCo Common Stock, by way of a pro rata distribution to its shareholders such that each holder of shares of Jacobs Common Stock was entitled to receive one share of SpinCo Common Stock for each share of Jacobs common stock held as of the record date, September 23, 2024 (the "Distribution"), and (iii) finally, Amentum Parent Holdings LLC merged with and into SpinCo, with SpinCo surviving the merger (the "Merger"). Amentum Holdings, Inc., as the surviving entity of the Separation Transaction is now an independent public company with common stock listed on the New York Stock Exchange under the symbol “AMTM” (“Amentum”).
In connection and in accordance with the terms of the Separation Transaction and prior to the Distribution and the Merger, Jacobs received a cash payment from SpinCo of approximately $911 million, after adjustments based on the estimated levels of cash, debt and working capital in the SpinCo Business as of the transaction date, and recorded estimated additional net working capital receivable amounts reflected in Receivables and Contract Assets in the Company's September 27, 2024 Consolidated Balance Sheet, subject to final settlement between the parties after the closing of the transaction and as set forth in the Agreement and Plan of Merger, dated as of November 20, 2023 (as amended, the “Merger Agreement"). Subsequent to the closing and upon final determination in March 2025, the parties determined that the Company was entitled to $70 million in final settlement of the post-closing working capital adjustment, resulting in a $24 million reduction from preliminary recorded receivable amounts, which was charged to Retained Earnings in the Company's Consolidated Balance Sheet. The $70 million final receivable balance was collected in
full on April 10, 2025 and immediately utilized to pay down existing amounts owed on Company’s Revolving Credit Facility upon receipt.

Investment in Amentum Stock
As a result of the Separation Transaction on September 27, 2024, Jacobs held approximately 29.2 million of the outstanding shares of Amentum common stock initially recorded on a net book value basis under spin-off accounting rules.
Following the Merger and in accordance with the Escrow Agreement, Jacobs transferred approximately 10.9 million of the 29.2 million of Amentum shares held into escrow to be held and distributed between the parties based on terms and conditions set forth in the Merger Agreement. The entire 29.2 million shares of Amentum, consisting of both the 10.9 million in escrow shares and the remaining 18.3 million shares owned by Jacobs was reflected in the Company’s September 27, 2024 Consolidated Balance Sheet pending final settlement of the escrow shares at a recorded fair value of $749.5 million.
In February 2025, in connection with the determination of SpinCo’s fiscal year 2024 performance against certain agreed upon milestones and ensuing escrow share settlement proceedings (the “Post-Closing Additional Merger Consideration Adjustment”), the parties agreed that Jacobs was entitled to receive at least an additional 1.2 million shares held in escrow, which were then released to Jacobs. Subsequently, on March 13, 2025, Jacobs completed the Equity-for-Debt Transaction (see Note 12- Borrowings for additional information). After giving effect to the above transactions, the Company's remaining investment in Amentum represented the 9.7 million shares remaining in escrow.
Further, on April 7, 2025, the parties agreed to a final determination of the Post-Closing Additional Merger Consideration Adjustment, pursuant to which Jacobs became entitled to receive approximately 7.3 million Amentum shares from the remaining 9.7 million shares held in escrow mentioned above, and former Amentum equity sponsors became entitled to receive the remainder of approximately 2.4 million shares. The finalization of the shares deemed owed to the former Amentum equity sponsors resulted in approximately $21.9 million in charges to Miscellaneous Expense in the Company's Consolidated Statement of Earnings in the second fiscal quarter of 2025. These shares were subsequently released to the respective parties during the current quarter.
Finally, on April 30, 2025, the Jacobs Board of Directors declared a dividend in kind to distribute the remaining 7.3 million shares of Amentum's stock to Jacobs’ shareholders of record as of May 16, 2025, which were distributed on a pro rata basis on May 30, 2025, resulting in an impact on retained earnings as shown on the Company's Consolidated Statements of Shareholders' Equity for the three and nine months ended June 27, 2025. Following the distribution, the Company no longer owns any shares of Amentum common stock.
The Company reported $27.4 million in net mark-to-market gains and other related transactions and $227.3 million in fair value mark-to-market and other related charges associated with the investment in Amentum shares for the three and nine month periods ending June 27, 2025, respectively, which was included in Miscellaneous Income (Expense), net as reported in Other Income (Expense) in the Company’s Consolidated Statement of Earnings.
Transition Services Agreement
Upon closing of the Separation Transaction, the Company entered into a Transition Services Agreement (the "TSA") with Amentum pursuant to which the Company, on an interim basis, will provide various services to Amentum including corporate, information technology, and project services. The initial term of the TSA began immediately following the closing of the transaction on September 27, 2024 and expires in September 2025, unless the parties agree to an extension. Pursuant to the terms of the TSA, the Company will receive payments for the interim services. Since inception of the TSA agreement, the Company has recognized costs recorded in SG&A expense incurred to perform the TSA, offset by $9.8 million and $31.5 million in TSA related income for such services that is reported in miscellaneous income (expense) for the three and nine month periods ended June 27, 2025.
Sale of Energy, Chemicals and Resources ("ECR") Business
On April 26, 2019, Jacobs completed the sale of its Energy, Chemicals and Resources ("ECR") business to Worley Limited, a company incorporated in Australia ("Worley"), for a purchase price of $3.4 billion consisting of (i) $2.8 billion in cash plus (ii) $58.2 million ordinary shares of Worley, subject to adjustments for changes in working capital and certain other items. For the three and nine month periods ended June 27, 2025, $0.5 million was reported in Net Earnings Attributable to Jacobs from Discontinued Operations on the Consolidated Statement of Earnings related to ECR, as compared to $0.5 million and $(0.9) million for the corresponding periods last year.

During the nine months ended June 27, 2025, there was a $0.10 increase in earnings per share resulting from adjustments to the redeemable noncontrolling interests to reflect the reduction of the excess in the redemption values over fair values of the B common shares component of the redeemable equity. During the nine months ended June 28, 2024, there was a $0.01 increase in earnings per share resulting from redemption value adjustments associated with redeemable noncontrolling interests preference share repurchase and reissuance activities that were recorded.
The changes above had no impact on the Company’s overall results of operations, financial position or cash flows. See Note 6- Earnings Per Share and Certain Related Information for more information.
Changes in the redeemable noncontrolling interests during the nine months ended June 27, 2025 are as follows (in thousands):

In addition, certain employees and non-employees of PA Consulting are eligible to receive equity-based incentive grants since the March 2, 2021 original investment date. Under the terms of the applicable agreements, these grants have reached vested status on a tranche basis of approximately 40% through June 2025, with the remaining 60% anticipated to vest and result in associated expense recognition upon a liquidity event, as defined in the applicable agreements, which is expected to take place in 2026. The Company has accrued cumulative expenses associated with the vested grants in the amounts of $50.6 million and $28.4 million reported in Other deferred liabilities in our Consolidated Balance Sheets as of June 27, 2025 and September 27, 2024, respectively.

Restructuring and Related Activities [Abstract]  
Restructuring and Other Charges Restructuring and Other Charges
During fiscal 2023, the Company implemented restructuring and separation initiatives relating to the Separation Transaction which continued through fiscal years 2024 and 2025 year to date and are expected to be substantially completed by the end of calendar year 2025. Restructuring initiatives were also implemented during fiscal 2023 relating to our investment in PA Consulting, which is substantially completed. While restructuring activities for each of these programs are comprised mainly of employee termination costs, the separation activities and costs are primarily related to the engagement of outside services, dedicated internal personnel and other related costs dedicated to the Separation Transaction.
Collectively, the above-mentioned restructuring activities are referred to as “Restructuring and other charges.”
The following table summarizes the impacts of the Restructuring and other charges by operating segment for the three and nine months ended June 27, 2025 and June 28, 2024 (in thousands):

Commitments and Contingencies Disclosure [Abstract]  
Commitments and Contingencies and Derivative Financial Instruments Commitments and Contingencies and Derivative Financial Instruments
Derivative Financial Instruments
The Company is exposed to interest rate risk under its variable rate borrowings and additionally, due to the nature of the Company's international operations, we are at times exposed to foreign currency risk. As such, we sometimes enter into foreign exchange hedging contracts and interest rate hedging contracts in order to limit our exposure to fluctuating foreign currencies and interest rates.
During fiscal 2022, the Company entered into two treasury lock agreements with a total notional value of $500.0 million to manage its interest rate exposure to the anticipated issuance of fixed rate debt before December 2023. On February 13, 2023, the Company settled these treasury lock agreements and issued the 5.90% Bonds in the aggregate principal amount of $500.0 million, which resulted in the receipt of cash and a pre-tax gain of $37.4 million, which is being amortized to interest expense and recognized over the term of the 5.90% Bonds. See Note 12- Borrowings for further discussion relating to the terms of the 5.90% Bonds. The unrealized net gain on these instruments was $21.6 million and $23.6 million, net of tax, and is included in accumulated other comprehensive income as of June 27, 2025 and September 27, 2024, respectively.
In fiscal 2020 we entered into interest rate swap agreements to manage the interest rate exposure on our variable rate loans. By entering into the swap agreements, the Company converted the variable rate based liabilities into fixed rate liabilities for a period of five to ten years. During the fiscal 2023 transition from LIBOR to SOFR, the terms of the swaps were amended accordingly and remained designated as cash-flow hedges in accordance with ASC 815, Derivatives and Hedging. As of June 27, 2025 and September 27, 2024, the Company has one ten-year outstanding instrument with a notional value of $200.0 million.
The fair value of the interest rate swap at June 27, 2025 and September 27, 2024 was $22.0 million and $23.0 million, respectively, included within miscellaneous other assets on the Consolidated Balance Sheet. The unrealized net gain on the interest rate swap as of June 27, 2025 and September 27, 2024 was $16.8 million and $17.4 million, respectively, net of tax, and was included in accumulated other comprehensive income.
Additionally, the Company held foreign exchange forward contracts in currencies that support our operations, including British Pound, Australian Dollar and other currencies, with notional values of $1.08 billion at June 27, 2025 and $827.3 million at September 27, 2024. The length of these contracts currently ranges from one to six months. The fair value of the foreign exchange contracts at June 27, 2025 was $15.3 million, of which $17.0 million is included within current assets and $(1.7) million is included within current liabilities on the Consolidated Balance Sheet as of June 27, 2025. The fair value of the contracts as of September 27, 2024 was $15.3 million, of which $15.8 million is included within current assets and $(0.5) million is included within current liabilities on the Consolidated Balance Sheet as of September 27, 2024. Associated income statement impacts are included in miscellaneous income (expense) in the Consolidated Statements of Earnings for both periods.
The fair value measurements of these derivatives are being made using Level 2 inputs under ASC 820, Fair Value Measurement, as the measurements are based on observable inputs other than quoted prices in active markets. We are exposed to risk from credit-related losses resulting from nonperformance by counterparties to our financial instruments. We perform credit evaluations of our counterparties under forward exchange and interest rate contracts and expect all counterparties to meet their obligations. We have not experienced credit losses from our counterparties.
Contractual Guarantees, Legal Proceedings, Claims, Investigations and Insurance
In the normal course of business, we make contractual commitments (some of which are supported by separate guarantees) and on occasion we are a party in a litigation or arbitration proceeding, such as the Consolidated JV Matter (see Note 19- Segment Information). The litigation or arbitration in which we are involved includes personal injury claims, professional liability claims and breach of contract claims. Where we provide a separate guarantee, it is strictly in support of the underlying contractual commitment. Guarantees take various forms including surety bonds required by law, or standby letters of credit ("LOC" and also referred to as “bank guarantees”) or corporate guarantees given to induce a party to enter into a contract with a subsidiary. Standby LOCs are also used as security for advance payments or in various other transactions. The guarantees have various expiration dates ranging from an arbitrary date to completion of our work (e.g., engineering only) to completion of the overall project. We record in the Consolidated Balance Sheets amounts representing our estimated liability relating to such guarantees, litigation and insurance claims. Guarantees are accounted for in accordance with ASC 460-10, Guarantees, at fair value at the inception of the guarantee.
At June 27, 2025 and September 27, 2024, the Company had issued and outstanding approximately $229.8 million and $306.2 million, respectively, in LOCs and $2.7 billion and $2.3 billion, respectively, in surety bonds.
We maintain insurance coverage for most insurable aspects of our business and operations. Our insurance programs have varying coverage limits depending upon the type of insurance and include certain conditions and exclusions which insurance companies may raise in response to any claim that is asserted by or against the Company. We have also elected to retain a portion of losses and liabilities that occur through using various deductibles, limits, and retentions under our insurance programs. As a result, we may be subject to a future liability for which we are only partially insured or completely uninsured. We intend to mitigate any such future liability by continuing to exercise prudent business judgment in negotiating the terms and conditions of the contracts which the Company enters with its clients. Our insurers are also subject to business risk and, as a result, one or more of them may be unable to fulfill their insurance obligations due to insolvency or otherwise.
Additionally, as a contractor providing services to the U.S. federal government, we are subject to many types of audits, investigations, and claims by, or on behalf of, the government including with respect to contract performance, pricing, cost allocations, procurement practices, labor practices, and socioeconomic obligations. Furthermore, our income, franchise, and similar tax returns and filings are also subject to audit and investigation by the Internal Revenue Service, most states within the United States, as well as by various government agencies representing jurisdictions outside the United States.
Our Consolidated Balance Sheets include amounts representing our probable estimated liability relating to such claims, guarantees, litigation, audits, and investigations. We perform an analysis to determine the level of reserves to establish for insurance-related claims that are known and have been asserted against us, as well as for insurance-related claims that are believed to have been incurred based on actuarial analysis but have not yet been reported to our claims administrators as of the respective balance sheet dates. We include any adjustments to such insurance reserves in our consolidated results of operations. Insurance recoveries are recorded as assets if recovery is probable and estimated liabilities are not reduced by expected insurance recoveries.
The Company believes, after consultation with counsel, that such guarantees, litigation, U.S. government contract-related audits, investigations and claims, and income tax audits and investigations should not have a material adverse effect on our consolidated financial statements, beyond amounts currently accrued.

Segment Reporting [Abstract]  
Segment Information Segment Information
The Company's two operating segments are comprised of Infrastructure and Advanced Facilities ("I&AF") and its majority investment in PA Consulting. Subsequent to the Separation Transaction, the SpinCo businesses are now presented as discontinued operations for all periods and therefore not reflected in the segment disclosures below. For further information, refer to Note 15- Discontinued Operations.
The Company’s Chief Executive Officer is the Chief Operating Decision Maker (“CODM”) and evaluates the performance of each of these segments and make appropriate resource allocations among each of the segments. For purposes of the Company’s goodwill impairment testing, it has been determined that the Company’s operating segments are also its reporting units based on management’s conclusion that the components comprising each of its operating segments share similar economic characteristics and meet the aggregation criteria for reporting units in accordance with ASC 350, Intangibles-Goodwill and Other.
Financial information for each segment is reviewed by the CODM to assess performance and make decisions regarding the allocation of resources. The CODM evaluates the operating performance of our operating segments using segment operating profit. The Company incurs certain SG&A that relate to its business as a whole which are not allocated to the segments.
The following tables present total revenues and segment operating profit from continuing operations for each reportable segment (in thousands) and includes a reconciliation of segment operating profit to total U.S. GAAP operating profit by including certain corporate-level expenses, Restructuring and other charges (as defined in Note 17- Restructuring and Other Charges) and transaction and integration costs (in thousands).

Fair Value and Fair Value Measurements
Certain amounts included in the accompanying consolidated financial statements are presented at fair value. Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants as of the date fair value is determined (the “measurement date”). When determining fair value, we consider the principal or most advantageous market in which we would transact, and we consider only those assumptions we believe a typical market participant would consider when pricing an asset or liability. In measuring fair value, we use the following inputs in the order of priority indicated:
Level 1 - Quoted prices in active markets for identical assets or liabilities.
Level 2 - Observable inputs other than quoted prices in active markets included in Level 1, such as (i) quoted prices for similar assets or liabilities; (ii) quoted prices in markets that have insufficient volume or infrequent transactions (e.g., less active markets); and (iii) model-driven valuations in which all significant inputs are observable or can be derived principally from, or corroborated with, observable market data for substantially the full term of the asset or liability.
Level 3 - Unobservable inputs to the valuation methodology that are significant to the fair value measurement.
Please refer to Note 2- Significant Accounting Policies of Notes to Consolidated Financial Statements included in our 2024 Form 10-K for a more complete discussion of the various items within the consolidated financial statements measured at fair value and the methods used to determine fair value. Please also refer to Note 18- Commitments and Contingencies and Derivative Financial Instruments for discussion regarding the Company's derivative instruments and Note 15- Discontinued Operations for discussion regarding the Company's investment in Amentum common shares.
The net carrying amounts of cash and cash equivalents, trade receivables and payables and short-term debt approximate fair value due to the short-term nature of these instruments. See Note 12- Borrowings for a discussion of the fair value of long-term debt.

The interest rate under the Revolving Credit Agreement also incorporates a modest sustainability-linked pricing adjustment, which resulted in a favorable interest rate adjustment to the Company in February 2025. The applicable SOFR rates, including applicable margins, at June 27, 2025 and September 27, 2024 were approximately 5.49% and 6.64%. Borrowings denominated in British pounds bear interest at an adjusted SONIA rate plus a margin of between 0.908% and 1.658%. There were no amounts drawn in British pounds as of June 27, 2025.
(2)The U.S. dollar denominated borrowings under the 2021 Term Loan Facility bear interest at either a SOFR rate plus a margin of between 0.975% and 1.725% or a base rate plus a margin of between 0% and 0.625% depending on the Company’s Consolidated Leverage Ratio or Debt Rating (each as defined in the Amended and Restated Term Loan Agreement (defined below)). The applicable SOFR rate, including applicable margins, for borrowings denominated in U.S. dollars at September 27, 2024 was approximately 6.52%.

(3)Borrowings under the 2025 Term Loan Facility will bear interest at either a SONIA rate or term SOFR rate plus a margin of between 0.975% and 1.60% or a base rate plus a margin of between 0% and 0.50% depending on the Company’s Consolidated Leverage Ratio. The applicable SOFR and SONIA rates, including applicable margins, at June 27, 2025 were approximately 5.43% for borrowings denominated in U.S. dollars and 5.22% for borrowings denominated in British pounds.
(4)The interest rate payable on the 5.90% Bonds (as defined below) may be increased by an additional 12.5 basis points on each of September 1, 2028 and September 1, 2030, based on whether or not the Company achieves the key performance indicators set forth in the First Supplemental Indenture (as defined below). Each key performance indicator is independent of the other. Therefore, we may achieve one, both, or neither.
