| Basis of Presentation | Basis of Presentation Unless the context otherwise requires: •References herein to “Jacobs” are to Jacobs Solutions Inc. and its predecessors; •References herein to the “Company”, “we”, “us” or “our” are to Jacobs Solutions Inc. and its consolidated subsidiaries; and •References herein to the “Group” are to the combined economic interests and activities of the Company and the persons and entities holding noncontrolling interests in our consolidated subsidiaries. On August 29, 2022, Jacobs Engineering Group Inc. ("JEGI"), the predecessor to Jacobs Solutions Inc., implemented a holding company structure, which resulted in Jacobs Solutions Inc. becoming the parent company of, and successor issuer to, JEGI (the "Holding Company Reorganization"). For purposes of this report, references to Jacobs and the "Company", "we", "us" or "our" or our management or business at any point prior to August 29, 2022 refer to JEGI, or JEGI and its consolidated subsidiaries as the predecessor to Jacobs Solutions Inc. The accompanying consolidated financial statements and financial information included herein have been prepared pursuant to the interim period reporting requirements of Form 10-Q. Consequently, certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted. Readers of this Quarterly Report on Form 10-Q should also read our consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the fiscal year ended September 26, 2025 (“2025 Form 10-K”). In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of our consolidated financial statements as of March 27, 2026, and for the three and six months ended March 27, 2026. Our interim results of operations are not necessarily indicative of the results to be expected for the full fiscal year. On January 2, 2026, Jacobs entered into an Implementation Deed (the “Implementation Deed”) with PA Consulting. Pursuant to the Implementation Deed and certain related agreements, and in accordance with the terms and conditions thereof, on March 20, 2026, Jacobs completed the transaction to acquire from shareholders of PA Consulting all of the remaining issued share capital of PA Consulting ("PA Shares") owned by the PA Consulting shareholders (excluding shares already held by Jacobs and its affiliates). The Company acquired the PA Shares for an aggregate initial consideration of approximately £1.21 billion which was paid through a combination of approximately £997.6 million in cash (net of certain PA Consulting shareholder expenses) and 2,043,537 newly issued shares of Jacobs' common stock, par value $1.00 per share (“Company Common Stock”). Also, on March 20, 2028, the Company will pay an additional £75 million in consideration with shares of Company Common Stock, cash or a combination thereof (as determined by the Company in its sole discretion), with accruals associated with this additional consideration reflected in Other deferred liabilities on the Consolidated Balance Sheet as of March 27, 2026. The transactions described in this paragraph, are collectively referred to as the “PA Consulting Transaction”. As a result of the PA Consulting Transaction, the Company no longer carries Redeemable Noncontrolling Interests on the Jacobs Consolidated Financial Statements. See Note 15- PA Consulting Redeemable Noncontrolling Interests for more discussion on the transaction and Note 12- Borrowings for more discussion on the financing for the transaction. On September 27, 2024, Jacobs Solutions Inc. ("Jacobs") completed the previously announced Reverse Morris Trust transaction pursuant to which (i) Jacobs first transferred its Critical Mission Solutions business (“CMS”) and portions of its Divergent Solutions (“DVS”) business (referred to herein as the Cyber & Intelligence business (“C&I”) and together with CMS referred to as the “SpinCo Business”), to Amazon Holdco Inc., a Delaware corporation, that was subsequently renamed Amentum Holdings, Inc. (“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 14- Discontinued Operations for more information.

| Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
| 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 2025 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 2025 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 17- Commitments and Contingencies and Derivative Financial Instruments for discussion regarding the Company's derivative instruments and Note 14- Discontinued Operations for discussion regarding the Company's former 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.

| Revenue Accounting for Contracts | Revenue Accounting for Contracts Disaggregation of Revenues 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 (including limited amounts of guaranteed maximum price) and fixed-price contracts. Our contracts are with many different customers in numerous industries. Refer to Note 18- 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 six months ended March 27, 2026 and March 28, 2025 (in thousands):
Contract Liabilities Contract liabilities represent amounts billed to clients in excess of revenue recognized to date. Revenue recognized for the three and six months ended March 27, 2026 that was previously included in the contract liability balance on September 26, 2025 was $169.6 million and $618.4 million, respectively. Revenue recognized for the three and six months ended March 28, 2025 that was included in the contract liability balance on September 27, 2024 was $172.2 million and $583.0 million, respectively. Remaining Performance Obligations The Company’s remaining performance obligations as of March 27, 2026 represent a measure of the total dollar value of work to be performed on contracts awarded and in progress. The Company had approximately $19.0 billion in remaining performance obligations as of March 27, 2026. The Company expects to recognize approximately 47% of its remaining performance obligations into revenue within the next twelve months and the remaining 53% 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 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 redeemable noncontrolling interests redemption value adjustment associated with the PA Consulting investment. In connection with the PA Consulting Transaction, the Company issued 2,043,537 shares of Company Common Stock. See Note 15- PA Consulting Redeemable Noncontrolling Interests for more discussion on the transaction.

We anticipate that substantially all of such unbilled amounts will be billed and collected over the next twelve months. Contract assets represent unbilled amounts where the right to payment is subject to more than merely the passage of time and includes performance-based incentives and services that have been provided in advance of agreed contractual milestones. Contract assets are transferred to unbilled receivables when the right to consideration becomes unconditional and are transferred to amounts billed upon invoicing.

| Borrowings | Borrowings At March 27, 2026 and September 26, 2025, long-term debt consisted of the following (principal amounts in thousands):
(1)The U.S. dollar denominated borrowings under the JSI Revolving Credit Facility (as defined below) bear interest at either a SOFR rate plus a margin of between 0.875% and 1.625% 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 JSI Revolving Credit Facility). The applicable SOFR rate, including applicable margins at March 27, 2026 was approximately 4.90%. (2)The borrowings under the 2026 Term Loan Facility - three-year bear interest at either a SOFR rate plus a margin of between 0.750% and 1.500% or a base rate plus a margin of between 0% and 0.500% depending on the Company’s Consolidated Leverage Ratio or Debt Rating. The applicable SOFR rate including applicable margins for borrowings denominated in U.S. dollars at March 27, 2026 was approximately 4.80%. (3)The borrowings under the 2026 Term Loan Facility- five-year bear interest at either a SOFR rate plus a margin of between 0.875% and 1.625% or a base rate plus a margin of between 0% and 0.625% depending on the Company’s Consolidated Leverage Ratio or Debt Rating. The applicable SOFR rate including applicable margins for borrowings denominated in U.S. dollars at March 27, 2026 was approximately 4.93%. (4)The U.S. dollar denominated borrowings under the Revolving Credit Facility bore 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 incorporated a modest sustainability-linked pricing adjustment, which resulted in a favorable interest rate adjustment to the Company in February 2025. The applicable SOFR rate, including applicable margins, at September 26, 2025 was approximately 5.37%. Borrowings denominated in British pounds bore 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 September 26, 2025. (5)Borrowings under the 2025 Term Loan Facility bore 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 or Debt Rating. The applicable SOFR and SONIA rates, including applicable margins, at September 26, 2025 were approximately 5.42% for borrowings denominated in U.S. dollars and 4.97% for borrowings denominated in British pounds. (6)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. We believe the carrying values of the JSI Revolving Credit Facility and the 2026 Term Loan Facility (as defined below) approximates fair value based on the interest rates and scheduled maturities applicable to the outstanding borrowings. The following table presents the estimated fair value of each outstanding bond based on Level 2 inputs as of March 27, 2026 (in thousands):
Revolving Credit Facility and Term Loans The Company and certain of its subsidiaries maintained 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 could 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 provided for a letter of credit sub facility of $400.0 million, and provided for a $100.0 million sub facility for swing line loans. Letters of credit were subject to fees based on the Company’s Consolidated Leverage Ratio or Debt Rating, whichever was more favorable to the Company. The Company is a guarantor of the obligations of JEGI and its subsidiaries under the Revolving Credit Agreement. The maturity date of the Revolving Credit Facility was February 6, 2028. However, on March 16, 2026 the Revolving Credit Facility was repaid and the JSI Revolving Credit Facility, a new revolving credit facility, was established (see below). On March 16, 2026, the Company, JEGI, and certain subsidiaries of the Company, entered into a $1.5 billion long-term unsecured, revolving credit facility (the “JSI Revolving Credit Facility”) with a syndicate of U.S. and international banks and financial institutions. The JSI Revolving Credit Facility permits the Company to borrow 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 letter of credit sub facility of $400.0 million, and provides for a $100.0 million sub facility for swing line loans, which are a part of, and not in addition to the overall aggregate borrowing limit. Letters of credit are subject to fees based on the Company’s Consolidated Leverage Ratio or Debt Rating, whichever is more favorable to the Company. The maturity date of the JSI Revolving Credit Facility is March 14, 2031. 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. 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 14- 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. On March 3, 2026, the Company repaid the outstanding obligations under the 2025 Term Loan Facility using proceeds from the offering and issuance of the 4.75% Bonds and 5.375% Bonds. On March 16, 2026, the Company, as borrower, and JEGI, as guarantor, entered into a unsecured term loan agreement (the “2026 Term Loan Facility”) with a syndicate of financial institutions as lenders. Under the 2026 Term Loan Facility, the Company borrowed a $700.0 million term loan for a term of three-years from the date of initial funding, maturing on March 16, 2029 and $500.0 million term loan for a term of five-years from the date of initial funding, maturing on March 14, 2031. The proceeds from the 2026 Term Loan Facility proceeds were used to fund the cash portion of the PA Consulting Transaction. We were in compliance with the covenants under the JSI Revolving Credit Facility and 2026 Term Loan Facility at March 27, 2026. 5.90% Bonds, due 2033 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”).

| Discontinued Operations | Discontinued Operations 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. 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 $911.0 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 $70.0 million in final settlement of the post-closing working capital adjustment, resulting in a $24.0 million reduction from preliminary recorded receivable amounts, which was charged to Retained Earnings in the Company's Consolidated Balance Sheet. The $70.0 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. Summarized Financial Information of Discontinued Operations The following table represents earnings from discontinued operations, net of tax (in thousands):
(1)Other expense, net for the three and six months ended March 27, 2026 was unfavorably impacted by $2.6 million related to foreign currency translation from an indemnity reserve in respect of an ongoing non-U.S. tax matter related to an entity that was part of the separated SpinCo Business. For the three and six months ended March 27, 2026, discontinued operations used $32.7 million of net cash flows from operating activities in connection with a previously recorded accrued liability, and there were no related investing or financing cash flows. No notable components of net cash flows from discontinued operations were included in our Consolidated Statements of Cash Flows for the three and six months ended March 28, 2025. No assets and liabilities remained held for spin as of March 27, 2026 and September 26, 2025 balance sheet dates. 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 third fiscal quarter of 2025. 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 year ended September 26, 2025. Following the distribution, the Company no longer owns any shares of Amentum common stock. The Company reported $109.5 million and $254.7 million in fair value mark-to-market losses and other related charges associated with the former investment in Amentum shares for the three and six months ended March 28, 2025, respectively, which were included in Miscellaneous expense 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. As of September 26, 2025, the TSA was substantially exited with certain agreed upon extensions which were completed as of December 26, 2025. Pursuant to the terms of the TSA, the Company received payments for the interim services. From inception of the TSA agreement, the Company recognized costs recorded in SG&A expense incurred to perform the TSA, offset by $10.3 million in TSA related income for such services that is reported in Miscellaneous expense for the three months ended March 28, 2025, with $0.1 million and $21.7 million respectively, for the six month periods ended March 27, 2026 and March 28, 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 six month periods ended March 28, 2025, there were no amounts reported in Net Loss Attributable to Jacobs from Discontinued Operations on the Consolidated Statement of Earnings related to ECR, with no significant activities during the fiscal 2026 periods presented.

| PA Consulting Redeemable Noncontrolling Interests | PA Consulting Redeemable Noncontrolling Interests In connection with the Company's strategic investment in PA Consulting on March 2, 2021, the Company recorded redeemable noncontrolling interests, including subsequent purchase accounting adjustments, representing the noncontrolling interest holders' equity interests in the form of preferred and common shares of PA Consulting, with substantially all of the value associated with these interests allocable to the preferred shares. Since the March 2, 2021 investment date, PA Consulting has been accounted for as a consolidated subsidiary and as a separate operating segment of the Company. On January 2, 2026, Jacobs entered into the Implementation Deed with PA Consulting. Pursuant to the Implementation Deed and certain related agreements, and in accordance with the terms and conditions thereof, on March 20, 2026, Jacobs completed the transaction to acquire from shareholders of PA Consulting all of the remaining issued share capital of PA Consulting ("PA Shares") owned by the PA Consulting shareholders (excluding shares already held by Jacobs and its affiliates). The Company acquired the PA Shares for an aggregate initial consideration of approximately £1.21 billion which was paid through a combination of approximately £997.6 million in cash (net of certain PA Consulting shareholder expenses) and 2,043,537 newly issued shares of Jacobs' common stock, par value $1.00 per share (“Company Common Stock”). Also, on March 20, 2028, the Company will pay an additional £75 million in consideration with shares of Company Common Stock, cash or a combination thereof (as determined by the Company in its sole discretion), with accruals associated with this additional consideration reflected in Other deferred liabilities on the Consolidated Balance Sheet as of March 27, 2026. The transactions described in this paragraph, are collectively referred to as the “PA Consulting Transaction”. As a result of the PA Consulting Transaction, the Company no longer carries Redeemable Noncontrolling Interests on the Jacobs Consolidated Financial Statements. See Note 12- Borrowings for discussion on the financing for the transaction. All of the shares of Company Common Stock issued for the initial consideration in connection with the PA Consulting Transaction (2,043,537 shares of Company Common Stock) are subject to a contractual lockup period that restricts any sale, assignment, pledge, or other transfer of those shares until March 20, 2027. The locked-up shares have the same voting, dividend, and other rights as Jacobs’ other outstanding common shares. The lockup restriction affects only the sale, assignment, pledge or other transfer of those shares and will expire by its terms on March 20, 2027, at which time such transfer restriction will lapse. As of March 27, 2026, 2,043,537 shares remain subject to the lockup. Also, in connection with the PA Consulting Transaction, approximately $113.5 million of initial consideration was paid on March 20, 2026 in cash for PA Consulting shares held to the PA Consulting employee benefit trust (the "PA Consulting EBT" - a consolidated entity of Jacobs), with these cash amounts reported as restricted cash in Prepaid expenses and other on the Consolidated Balance Sheets as of March 27, 2026. Further, upon the recommendation of the PA Consulting shareholder representatives, this restricted cash is anticipated to be distributed by the trustees of the PA Consulting EBT to PA Consulting employees that were employed by PA Consulting as of the March 20, 2026 transaction completion date, with the majority of this distribution expected to take place in the third quarter of fiscal year 2026 (also see the Restricted Cash section of this footnote below for more information). Based on the terms of the agreements, this amount represents compensation expense incurred related to the transaction with associated charges reflected in Selling, general and administrative expense on the accompanying Consolidated Statements of Earnings and related accruals reported in Accrued liabilities on the Consolidated Balance Sheets as of March 27, 2026. In addition, approximately $10.4 million of the deferred consideration discussed above is also payable to the PA Consulting EBT, which will be distributed to PA Consulting employees on March 20, 2028. Similar to the terms and conditions described above, this amount represents compensation expense incurred as of the transaction date and is also reflected in Selling, general and administrative expense on the accompanying Consolidated Statements of Earnings and in Other deferred liabilities on the Consolidated Balance Sheets as of and for the period ended March 27, 2026. Other transaction costs associated with the PA Consulting Transaction of $36.0 million is reflected within Retained earnings and presented in the Consolidated Statements of Stockholders' Equity for the six months ended March 27, 2026. Prior to the PA Consulting Transaction, during the first half of fiscal 2026 and 2025, PA Consulting repurchased certain shares of the redeemable noncontrolling interest holders for $0.4 million and $4.1 million respectively, in cash. The difference between the cash purchase prices and the recorded book values of these repurchased and issued interests was recorded in the Company’s consolidated retained earnings. The Company held approximately 71% of the outstanding ownership of PA Consulting prior to the PA Consulting Transaction completion date and as of September 26, 2025. During the first half of fiscal 2026 and 2025, there were adjustments of $0.11 and $0.05, respectively, to consolidated earnings per share resulting from adjustments to the redeemable noncontrolling interests to reflect the excess of redemption values over fair values of the B common shares component of the redeemable noncontrolling interests. The redemption value adjustments associated with redeemable noncontrolling interests preference share repurchase and reissuance activities that were recorded had an immaterial impact to earnings per share for the six months ended March 27, 2026 and March 28, 2025. As a result of the PA Consulting Transaction, these shares were redeemed at fair value therefore there was no cumulative impact to EPS. 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 six months ended March 27, 2026 are as follows (in thousands):
In addition, certain employees and non-employees of PA Consulting were eligible to receive equity-based incentive grants since the March 2, 2021 original investment date. Under the terms of the applicable agreements, these grants reached vested status on a tranche basis of approximately 40% through July 2025, and the remaining 60% vested on March 20, 2026 upon completion of the PA Consulting Transaction. The previously recorded accrued liabilities in connection with the vested grants under these agreements (reported in Other deferred liabilities on our Consolidated Balance Sheets at fair value) were settled with transaction proceeds in connection with the PA Consulting Transaction on March 20, 2026. No remaining unrecognized compensation costs are expected to be incurred in connection with these agreements in the future. As of September 26, 2025, the liabilities for the vested grants associated with these equity-based incentive agreements were reported at fair value in the amount of $103.8 million and reflected in Other deferred liabilities in our Consolidated Balance Sheets. Further, during the six months ended March 27, 2026 and March 28, 2025, the Company has recorded $237.5 million and $13.9 million, respectively, in expenses associated with these agreements, which were reflected in Selling, general and administrative expenses in the Consolidated Statements of Earnings. Restricted Cash The Company's Consolidated Balance Sheets include restricted cash amounts of $116.5 million and $1.4 million at March 27, 2026 and September 26, 2025, respectively, in PA Consulting subsidiaries that is restricted from general use and is reflected in Prepaid expenses and other, with the increase due primarily to the PA Consulting Transaction as described above.

| Restructuring and Other Charges | Restructuring and Other Charges During fiscal 2023, the Company implemented restructuring and separation initiatives relating to the Separation Transaction (see Note 14- Discontinued Operations for additional information) which continued through fiscal years 2024 and 2025; Jacobs has substantially completed the restructuring program for the Separation Transaction at the end of calendar year 2025. Restructuring initiatives were also implemented during fiscal 2023 relating to our PA Consulting business, which are substantially completed. During fiscal 2026, the Company implemented integration initiatives relating to the PA Consulting Transaction (see Note 15- PA Consulting Redeemable Noncontrolling Interests for additional information). While restructuring activities for these programs are comprised mainly of employee termination costs, the separation and integration activities are primarily related to the engagement of outside services, dedicated internal personnel and other related costs dedicated to those transactions. 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 six months ended March 27, 2026 and March 28, 2025 (in thousands):
(1)The three and six months ended March 27, 2026 and March 28, 2025 included approximately $7.6 million and $9.9 million, respectively, and $10.2 million and $25.1 million, respectively, in restructuring and other charges relating to the Separation Transaction (primarily employee separation costs and professional services). The three and six months ended March 27, 2026 included approximately $6.5 million and $8.3 million in restructuring and other charges relating to the PA Consulting Transaction (primarily professional services and dedicated internal personnel), which were included in Operating (loss) profit in the Company's Consolidated Statement of Earnings (mainly in SG&A). The activity in the Company’s accruals for Restructuring and other charges for the six months ended March 27, 2026 is as follows (in thousands):

Mar. 27, 2026 | |
| 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 $19.5 million and $20.9 million, net of tax, and is included in Accumulated other comprehensive loss as of March 27, 2026 and September 26, 2025, 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 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 March 27, 2026 and September 26, 2025, 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 March 27, 2026 and September 26, 2025 was $20.0 million and $20.5 million, respectively, included within miscellaneous other assets on the Consolidated Balance Sheet. The unrealized net gain on the interest rate swap as of March 27, 2026 and September 26, 2025 was $15.2 million and $15.6 million, respectively, net of tax, and was included in Accumulated other comprehensive loss. 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 $1.89 billion at March 27, 2026 and $491.9 million at September 26, 2025. The length of these contracts currently ranges from to three months. The fair value of the foreign exchange contracts at March 27, 2026 was $2.8 million, of which $4.8 million is included within current assets and $(2.0) million is included within current liabilities on the Consolidated Balance Sheet as of March 27, 2026. The fair value of the contracts as of September 26, 2025 was $(0.3) million, of which $(2.3) million is included within current liabilities and $2.0 million is included within current assets on the Consolidated Balance Sheet as of September 26, 2025. Associated income statement impacts are included in Miscellaneous expense in the Consolidated Statements of Earnings for both periods. In addition, on January 5, 2026, in connection with the PA Consulting Transaction, the Company entered into a foreign exchange forward contract with a notional value of $1.31 billion to manage its exposure to fluctuations in foreign currency exchange rates arising from its obligation to deliver the cash portion of the initial consideration payable in such transaction. On March 12, 2026 the company entered into an additional hedge with a notional value of $60.1 million to offset the original hedged amount. These were subsequently settled on March 18, 2026 and a combined loss of $(20.5) million was recorded in Miscellaneous expense in the Consolidated Statements of Earnings as of March 27, 2026. 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. Leases The Company’s right-of use assets and lease liabilities presented on the Consolidated Balance Sheets relate to real estate, project assets used in connection with long-term construction contracts, IT assets and vehicles. The Company’s lease obligations are primarily for the use of office space and are primarily operating leases. The respective components of lease expense are reflected in Selling, general and administrative expenses on the Consolidated Statements of Earnings for all periods presented. 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 18- 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 March 27, 2026 and September 26, 2025, the Company had issued and outstanding approximately $253.4 million and $217.0 million, respectively, in LOCs and $3.0 billion and $2.8 billion, respectively, in surety bonds. Of the outstanding LOC amount, $0.3 million has been issued under the JSI Revolving Credit Facility and $253.1 million are issued under separate, committed and uncommitted letter-of-credit facilities. 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. On January 2, 2026, Jacobs entered into the Implementation Deed with PA Consulting, pursuant to which (and certain related agreements) Jacobs UK Holdings Limited acquired from shareholders of PA Consulting, other than Jacobs and its affiliates, all of the remaining issued share capital of PA Consulting owned by such shareholders in the PA Consulting Transaction. The transaction was completed on March 20, 2026. Jacobs agreed to unconditionally and irrevocably guarantee, for the period between signing of and closing of the transaction, to the other parties the performance and observance by Jacobs UK Holdings Limited of all its obligations, commitments, undertakings and warranties under the Implementation Deed. For further information, refer to Note 15- PA Consulting Redeemable Noncontrolling Interests.

| 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 14- Discontinued Operations. The Company’s Chief Executive Officer is the Chief Operating Decision Maker (“CODM”) and evaluates the performance of and makes appropriate resource allocations to 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 CODM does not review segment assets as a measure of segment performance. The following tables present total revenues, direct cost of contracts, selling, general and administrative expenses 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 16- Restructuring and Other Charges) and transaction and integration costs (in thousands) for the three and six months ended:

| 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.
|
| 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 2025 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 17- Commitments and Contingencies and Derivative Financial Instruments for discussion regarding the Company's derivative instruments and Note 14- Discontinued Operations for discussion regarding the Company's former 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.
