| Description of Business and Basis of Presentation | Description of Business and Basis of Presentation Description of Business Jacobs Solutions Inc. ("Jacobs" or "the Company") is a leading global professional services company that designs and deploys technology-centric solutions to solve many of the world’s most complex challenges. The services Jacobs provides to end markets fall into the following two operating segments: Infrastructure & Advanced Facilities and our investment in PA Consulting Group Limited ("PA Consulting"). See Note 19- Segment Information. From advisory and consulting, feasibility, planning, design, program and lifecycle management, Jacobs provides end-to-end services in advanced manufacturing, cities & places, energy, environmental, life sciences, transportation and water. Jacobs provides its services through offices and subsidiaries located primarily in North America, Europe, the Middle East, India, Australia, New Zealand and Asia. Jacobs provides its services under cost-reimbursable (including limited amounts of guaranteed maximum price) and fixed-price contracts, with fixed-price contracts comprised mainly of professional services arrangements and in some limited cases, construction. The percentage of revenues realized from each of these types of contracts for the fiscal years ended September 26, 2025, September 27, 2024 and September 29, 2023 was as follows:
Basis of Presentation, Definition of Fiscal Year, and Other Matters The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") and include the accounts of Jacobs Solutions Inc. and its subsidiaries and affiliates which it controls. All intercompany accounts and transactions have been eliminated in consolidation. The Company’s fiscal year ends on the Friday closest to September 30 (determined on the basis of the number of workdays) and, accordingly, an additional week of activity is added every five-to-six years. Fiscal 2020 included an extra week of activity. 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. Additionally, current and non-current assets and liabilities of the Disposal Group were reflected as held for spin in the Consolidated Balance Sheets prior to the Separation Transaction and no amounts remain held for spin as of September 27, 2024 and September 26, 2025. See Note 14- Discontinued Operations for more information.

| Accounting Policies [Abstract] | |
| Significant Accounting Policies | Significant Accounting Policies Revenue Accounting for Contracts Engineering, Procurement & Construction Contracts, Service Contracts and Software Contracts The Company recognizes engineering, procurement, and construction contract revenue over time, as performance obligations are satisfied, due to the continuous transfer of control to the customer in accordance with ASC Topic 606, Revenue from Contracts with Customers. Contracts which include engineering, procurement and construction services are generally accounted for as a single deliverable (a single performance obligation). In some instances, the Company’s services associated with a construction activity are limited to specific tasks such as customer support, consulting or supervisory services. In these instances, the services are typically identified as separate performance obligations. The Company recognizes revenue using the percentage-of-completion method, based primarily on contract costs incurred to date compared to total estimated contract costs. Estimated contract costs include the Company’s latest estimates using judgments with respect to labor hours and costs, materials, and subcontractor costs. The percentage-of-completion method (an input method) is the most representative depiction of the Company’s performance because it directly measures the value of the services transferred to the customer. Subcontractor materials, labor and equipment and, in certain cases, customer-furnished materials and labor and equipment are included in revenue and cost of revenue when management believes that the company is acting as a principal rather than as an agent (e.g., the company significantly integrates the materials, labor and equipment into the deliverables promised to the customer or is otherwise primarily responsible for fulfillment and acceptability of the materials, labor and/or equipment). The Company recognizes revenue, but not profit, on certain uninstalled materials that are not specifically produced, fabricated, or constructed for a project. Changes to total estimated contract cost or losses, if any, are recognized in the period in which they are determined as assessed at the contract level. Pre-contract costs are expensed as incurred unless they are expected to be recovered from the client. Project mobilization costs are generally charged to project costs as incurred when they are an integrated part of the performance obligation being transferred to the client. Under the typical payment terms of our engineering, procurement and construction contracts, amounts are billed as work progresses in accordance with agreed-upon contractual terms at periodic intervals (e.g., biweekly or monthly) and customer payments are typically due within 30 to 60 days of billing, depending on the contract. For service contracts, the Company recognizes revenue over time using the cost-to-cost percentage-of-completion method. For contracts with multiple performance obligations, the Company allocates the transaction price to each performance obligation using an estimate of the stand-alone selling price of each distinct service in the contract. In some instances where the Company is standing ready to provide services, the Company recognizes revenue ratably over the service period. When the Company has operations and maintenance or secondment contracts that do not contain variable consideration or have significant timing differences between cash payment and performance, the practical expedient method is applied for revenue recognition. Under the typical payment terms of our service contracts, amounts are billed as work progresses in accordance with agreed-upon contractual terms, and customer payments are typically due within 30 to 60 days of billing, depending on the contract. Revenue for certain contracts related to the sale of software licenses is recognized at a point in time, typically at the time of delivery, in accordance with ASC 606. The software license sale will be treated as a performance obligation separate and distinct from any related service and maintenance. Direct cost of contracts include all costs incurred in connection with and directly for the benefit of client contracts, including depreciation and amortization relating to assets used in providing the services required by the related projects. The level of direct cost of contracts may fluctuate between reporting periods due to a variety of factors, including the amount of pass-through costs we incur during a period. On those projects where we are acting as principal for subcontract labor or third-party materials and equipment, we reflect the amounts of such items in both revenues and costs (and we refer to such costs as “pass-through costs”). Back charges to suppliers or subcontractors are recognized as a reduction of cost when it is determined that recovery of such cost is probable, and the amounts can be reliably estimated. Disputed back charges are recognized when the same requirements described above have been satisfied. Variable Consideration The nature of the Company’s contracts gives rise to several types of variable consideration, including claims and unpriced change orders; awards and incentive fees; and liquidated damages and penalties. The Company recognizes revenue for variable consideration when it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. The Company estimates the amount of revenue to be recognized on variable consideration using the expected value (i.e., the sum of a probability-weighted amount) or the most likely amount method, whichever is expected to better predict the amount. Factors considered in determining whether revenue associated with claims (including change orders in dispute and unapproved change orders in regard to both scope and price) should be recognized include the following: (a) the contract or other evidence provides a legal basis for the claim, (b) additional costs were caused by circumstances that were unforeseen at the contract date and not the result of deficiencies in the company’s performance, (c) claim-related costs are identifiable and considered reasonable in view of the work performed, and (d) evidence supporting the claim is objective and verifiable. If the requirements for recognizing revenue for claims or unapproved change orders are met, revenue is recorded only when the costs associated with the claims or unapproved change orders have been incurred and only up to the amount of consideration that is probable of not being reversed. The Company generally provides limited warranties for work performed under its engineering and construction contracts. The warranty periods typically extend for a limited duration following substantial completion of the Company’s work on the project. Historically, warranty claims have not resulted in material costs incurred for which the Company was not compensated for by the customer. See Note 3- Revenue Accounting for Contracts for further discussion. Joint Ventures and VIEs As is common to the industry, we execute certain contracts jointly with third parties through various forms of joint ventures. Although the joint ventures own and hold the contracts with the clients, the services required by the contracts are typically performed by us and our joint venture partners, or by other subcontractors under subcontracting agreements with the joint ventures. Many of these joint ventures are formed for a specific project. The assets of our joint ventures generally consist almost entirely of cash and receivables (representing amounts due from clients), and the liabilities of our joint ventures generally consist almost entirely of amounts due to the joint venture partners (for services provided by the partners to the joint ventures under their individual subcontracts) and other subcontractors. In general, at any given time, the equity of our joint ventures represents the undistributed profits earned on contracts the joint ventures hold with clients. Very few of our joint ventures have employees or third-party debt or credit facilities. The debt held by the joint ventures is non-recourse to the general credit of Jacobs. The assets of a joint venture are available for use for the obligations of the particular joint venture and not for general operations of the Company. Our risk of loss on these arrangements is usually shared with our partners. The liability of each partner is usually joint and several, which means that each partner may become liable for the entire risk of loss on the project. Furthermore, on some of our projects, the Company has granted guarantees which may encumber both our contracting subsidiary company and the Company for the entire risk of loss on the project. The Company is unable to estimate the maximum potential amount of future payments that we could be required to make under outstanding performance guarantees related to joint venture projects due to a number of factors, including but not limited to, the nature and extent of any contractual defaults by our joint venture partners, resource availability, potential performance delays caused by the defaults, the location of the projects, and the terms of the related contracts. See Note 18- Contractual Guarantees, Litigation, Investigations and Insurance for further discussion. Most of the joint ventures are deemed to be variable interest entities (“VIE”) because they lack sufficient equity to finance the activities of the joint venture. The Company uses a qualitative approach to determine if the Company is the primary beneficiary of the VIE, which considers factors that indicate a party has the power to direct the activities that most significantly impact the joint venture’s economic performance. These factors include the composition of the governing board, how board decisions are approved, the powers granted to the operational manager(s) and partner that holds that position(s), and to a certain extent, the partner’s economic interest in the joint venture. The Company analyzes each joint venture initially to determine if it should be consolidated or unconsolidated. •Consolidated if the Company is the primary beneficiary of a VIE or holds the majority of voting interests of a non-VIE (and no significant participative rights are available to the other partners). •Unconsolidated if the Company is not the primary beneficiary of a VIE or does not hold the majority of voting interest of a non-VIE. Our unconsolidated joint ventures (including equity method investments) are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment might not be recoverable, and impairment losses are recognized for such investments if there is a decline in fair value below carrying value that is considered to be other-than-temporary. See Note 8- Joint Ventures, VIEs and Other Investments for further discussion. 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. 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 9- Borrowings for a discussion of the fair value of long-term debt. Certain other assets and liabilities, such as forward contracts and interest rate swap agreements we purchased as cash-flow hedges discussed in Note 17- Commitments and Contingencies and Derivative Financial Instruments and the Company's investment in Amentum ordinary shares discussed in Note 14- Discontinued Operations are required to be carried in our Consolidated Financial Statements at Fair Value. The fair value of the Company’s reporting units (when a quantitative impairment analysis is required for the purpose of determining whether there is an impairment of the carrying value of goodwill) is determined using an income and market approach. Both approaches require us to make certain estimates and judgments. Under the income approach, fair value is determined by using the discounted cash flows of our reporting units. Under the market approach, the fair values of our reporting units are determined by reference to guideline companies that are reasonably comparable to our reporting units; the fair values are estimated based on the valuation multiples of earnings before taxes, interest, depreciation and amortization associated with the guideline companies. In assessing whether the carrying value of goodwill has been impaired, we utilize the results of both valuation techniques and consider the range of fair values indicated. With respect to equity-based compensation (i.e., share-based payments), we estimate the fair value of stock options granted to employees and directors using the Black-Scholes option-pricing model. Like all option-pricing models, the Black-Scholes model requires the use of subjective assumptions including (i) the expected volatility of the market price of the underlying stock, and (ii) the expected term of the award, among others. Accordingly, changes in assumptions and any subsequent adjustments to those assumptions can cause different fair values to be assigned to our future stock option awards. For restricted stock awards (including restricted stock units) containing service and performance conditions, fair value is based on the closing stock price on the date of grant, adjusted for the expected level of achievement for any performance conditions. The fair values of the assets owned by the various pension plans that the Company sponsors are determined based on the type of asset, consistent with U.S. GAAP. Equity securities are valued by using market observable data such as quoted prices. Publicly traded corporate equity securities are valued at the last reported sale price on the last business day of the year. Securities not traded on the last business day are valued at the last reported bid price. Fixed income investment funds categorized as Level 2 are valued by the trustee using pricing models that use verifiable observable market data (e.g., interest rates and yield curves observable at commonly quoted intervals), bids provided by brokers or dealers, or quoted prices of securities with similar characteristics. Real estate consists primarily of common or collective trusts, with underlying investments in real estate. These investments are valued using the best information available, including quoted market price, market prices for similar assets when available, internal cash flow estimates discounted at an appropriate interest rate, or independent appraisals, as appropriate. Management values insurance contracts and hedge funds using actuarial assumptions and certain values reported by fund managers. Fair value measurements relating to our business combinations are made primarily using Level 3 inputs including discounted cash flow and to the extent applicable, Monte Carlo simulation techniques. Fair value for the identified intangible assets is generally estimated using inputs primarily for the income approach using the multiple period excess earnings method and the relief from royalties method. The significant assumptions used in estimating fair value include (i) revenue projections of the business, including profitability, (ii) attrition rates and (iii) the estimated discount rate that reflects the level of risk associated with receiving future cash flows. Other personal property assets, such as furniture, fixtures and equipment, are valued using the cost approach, which is based on replacement or reproduction costs of the asset less depreciation. The fair value of the contingent consideration is estimated using a Monte Carlo simulation and the significant assumptions used include projections of revenues and probabilities of meeting those projections. Key inputs to the valuation of the noncontrolling interests include projected cash flows and the expected volatility associated with those cash flows. The fair values for the asset groups relating to the impairment assessment of long-lived assets (see Note 10- Leases) were estimated primarily using discounted cash flow models (income approach) with Level 3 inputs. The significant assumptions used in estimating fair value include the expected downtime prior to the commencement of future subleases, projected sublease income over the remaining lease periods and discount rates that reflects the level of risk associated with receiving future cash flows. The methodologies described above and elsewhere in these Notes to Consolidated Financial Statements may produce a fair value measure that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes Level 3 valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement. Cash Equivalents We consider all highly liquid investments with original maturities of less than three months to be cash equivalents. Cash equivalents at September 26, 2025 and September 27, 2024 consisted primarily of money market mutual funds and overnight bank deposits. Receivables, Contract Assets and Contract Liabilities Receivables include amounts billed, net and unbilled receivables. Amounts billed, net consist of amounts invoiced to clients in accordance with the terms of our client contracts and are shown net of an allowance for expected credit losses. We anticipate that substantially all of such billed amounts will be collected over the next twelve months. Unbilled receivables and other, which represent an unconditional right to payment subject only to the passage of time in connection with our client contracts, are reclassified to amounts billed when they are billed under the terms of the contract. 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 provided ahead 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. Contract liabilities represent amounts billed to clients in excess of revenue recognized to date. Amounts will be earned based on achievement of deliverables. Property, Equipment, and Improvements Property, equipment and improvements are carried at cost, and are shown net of accumulated depreciation and amortization in the accompanying Consolidated Balance Sheets. Depreciation and amortization are computed primarily by using the straight-line method over the estimated useful lives of the assets. The cost of leasehold improvements is amortized using the straight-line method over the lesser of the estimated useful life of the asset or the remaining term of the related lease. Estimated useful lives are 40 years for buildings and range from 3 to 10 years for equipment and from 1 to 13 years for leasehold improvements. Goodwill and Other Intangible Assets Goodwill represents the excess of the cost of an acquired business over the fair value of the net tangible and intangible assets acquired. Goodwill and intangible assets with indefinite lives are not amortized; instead, on an annual basis we test goodwill and intangible assets with indefinite lives for possible impairment. Intangible assets with finite lives are amortized on a straight-line basis over the useful lives of those assets. For purposes of impairment testing, goodwill is assigned to the applicable reporting units based on the current reporting structure. We have determined that our operating segments are also our reporting units based on management’s conclusion that the components comprising each of our operating segments share similar economic characteristics and meet the aggregation criteria in accordance with ASC 350. We perform our annual goodwill impairment assessment as of the first day of the fourth fiscal quarter each year. We begin with the qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying value before applying the quantitative assessment described below. If it is determined through the evaluation of events or circumstances that the carrying value may not be recoverable, the Company then compares the fair value of the related reporting unit with its carrying amount. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized. For the 2025 fiscal year, we determined that the fair values of reporting units significantly exceeded their carrying values and an analysis beyond the qualitative level was not considered necessary. Impairment of Long-Lived Assets Our long-lived assets other than goodwill principally consist of right-of-use (ROU) lease assets, property, equipment and improvements, and finite-lived intangible assets. These long-lived assets are evaluated for impairment for each of our asset groups in accordance with ASC 360 by first identifying whether indicators of impairment exist. If such indicators are present, we assess long-lived asset groups for recoverability based on estimated future undiscounted cash flows. For asset groups where the recoverability test fails, the fair value of each asset group is then estimated and compared to its carrying amount. An impairment loss is recognized for the amount by which an asset group’s carrying value exceeds its fair value. Foreign Currencies In preparing our Consolidated Financial Statements, it is necessary to translate the financial statements of our subsidiaries operating outside the U.S., which are denominated in currencies other than the U.S. dollar, into the U.S. dollar. In accordance with U.S. GAAP, revenues and expenses of operations outside the U.S. are translated into U.S. dollars using weighted-average exchange rates for the applicable periods being translated while the assets and liabilities of operations outside the U.S. are generally translated into U.S. dollars using period-end exchange rates. The net effect of foreign currency translation adjustments is included in stockholders’ equity as a component of accumulated other comprehensive loss in the accompanying Consolidated Balance Sheets. Share-Based Payments We measure the value of services received from employees and directors in exchange for an award of an equity instrument based on the grant-date fair value of the award. The fair value is recognized as a non-cash cost on a straight-line basis over the period the individual provides services, which is typically the vesting period of the award with the exception of awards containing an internal performance measure, such as Earnings Per Share growth and Return on Invested Capital, which is recognized on a straight-line basis over the vesting period subject to the probability of meeting the performance requirements and adjusted for the number of shares expected to be earned. The cost of these awards is recorded in selling, general and administrative expenses in the accompanying Consolidated Statements of Earnings. Concentrations of Credit Risk Our cash balances and cash equivalents are maintained in accounts held by major banks and financial institutions located in North America, South America, Europe, the Middle East, India, Australia, Africa and Asia. In the normal course of business, and consistent with industry practices, we grant credit to our clients without requiring collateral. Concentrations of credit risk is the risk that, if we extend a significant amount of credit to clients in a specific geographic area or industry, we may experience disproportionately high levels of default if those clients are adversely affected by factors particular to their geographic area or industry. Concentrations of credit risk relative to trade receivables are limited due to our diverse client base, which includes the U.S. federal government and multi-national corporations operating in a broad range of industries and geographic areas. Additionally, in order to mitigate credit risk, we continually evaluate the credit worthiness of our major commercial clients. Leases The Company accounts for its leases in accordance with ASC 842, Leases ("ASC 842"). ASC 842 requires lessees to recognize assets and liabilities for most leases. The Company determines if an arrangement is a lease at contract inception. A lease exists when a contract conveys to the customer the right to control the use of an identified asset for a period of time in exchange for consideration. The definition of a lease embodies two conditions: (1) there is an identified asset in the contract, and (2) the customer has the right to control the use of the identified asset. Lessees are required to classify leases as either finance or operating leases. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. The Company’s right-of use assets and lease liabilities relate to real estate, project assets used in connection with long-term construction contracts, IT assets and vehicles. The Company’s leases have remaining lease terms of less than one year to eighteen years. The Company’s lease obligations are primarily for the use of office space and are primarily operating leases. Certain of the Company’s leases contain renewal, extension, or termination options. The Company assesses each option on an individual basis and will only include options reasonably certain of exercise in the lease term. The Company generally considers the base term to be the term provided in the contract. None of the Company’s lease agreements contain material options to purchase the leased property, material residual value guarantees, or material restrictions or covenants. Long-term project asset and vehicle leases (leases with terms greater than twelve months), along with all real estate and IT asset leases, are recorded on the consolidated balance sheet at the present value of the minimum lease payments not yet paid. Because the Company primarily acts as a lessee and the rates implicit in its leases are not readily determinable, the Company generally uses its incremental borrowing rate on the lease commencement date to calculate the present value of future lease payments. Certain leases include payments that are based solely on an index or rate. These variable lease payments are included in the calculation of the ROU asset and lease liability and are initially measured using the index or rate at the lease commencement date. Other variable lease payments, such as payments based on use and for property taxes, insurance, or common area maintenance that are based on actual assessments are excluded from the ROU asset and lease liability and are expensed as incurred. In addition to the present value of the future lease payments, the calculation of the ROU asset also includes any deferred rent, lease prepayments and initial direct costs of obtaining the lease, such as commissions. Certain lease contracts contain non-lease components such as maintenance and utilities. The Company has made an accounting policy election, as allowed under ASC 842-10-15-37 and discussed above, to capitalize both the lease component and non-lease components of its contracts as a single lease component for all of its right-of-use assets. Short-term project asset and vehicle leases (project asset and vehicle leases with an initial term of twelve months or less or leases that are cancellable by the lessee and lessor without significant penalties) are not recorded on the consolidated balance sheet and are expensed on a straight-line basis over the lease term. The majority of the Company’s short-term leases relate to equipment used on construction projects. These leases are entered into at agreed upon hourly, daily, weekly or monthly rental rates for an unspecified duration and typically have a termination for convenience provision. Such equipment leases are considered short-term in nature unless it is reasonably certain that the equipment will be leased for a term greater than twelve months. Pensions We use certain assumptions and estimates in order to calculate periodic pension cost and the value of the assets and liabilities of our pension plans. These assumptions involve discount rates, investment returns, and projected salary increases, among others. Changes in the actuarial assumptions may have a material effect on the plans’ liabilities and the projected pension expense. We use a corridor approach to amortize actuarial gains and losses. Under this approach, net gains or losses in excess of ten percent of the larger of the pension benefit obligation or the market-related value of the assets are amortized on a straight-line basis. The period of amortization is the average remaining service of active participants who are expected to receive benefits under certain plans and the average remaining future lifetime of plan participants for certain plans. We measure our defined benefit plan assets and obligations as of the end of the month closest to their fiscal year end, which is September 26, 2025 as the alternative measurement date in accordance with FASB guidance ASU 2015-04, Compensation Retirement Benefit (Topic 715): Practical Expedient for the Measurement Date of an Employer’s Defined Benefit Obligation and Plan Asset. This guidance allows employers with fiscal year ends that do not coincide with a calendar month end to make an accounting policy election to measure defined benefit plan assets and obligations as of the end of the month closest to their fiscal year end. Redeemable Noncontrolling Interests In connection with the PA Consulting investment in March 2021, the Company recorded redeemable noncontrolling interests, representing the interest holders' initial 35% equity interest in the form of preferred and common shares of PA Consulting. The preferred shares are entitled to a cumulative annual compounding 12% dividend based on the outstanding preferred share subscription price. These noncontrolling interest holders have certain option rights to put the preferred and common share interests back to the Company at a value based on the fair value of PA Consulting (the redemption values). The primary inputs and assumptions impacting the fair value of PA Consulting include projections of revenue and earnings before interest, taxes, depreciation and amortization and discount rates applied thereto. Additionally, the Company has an option to call the interests for certain individual shareholders in certain circumstances. Because the interests are redeemable at the option of the holders and not solely within the control of the Company, the Company classified the interests in redeemable noncontrolling interests within its Consolidated Balance Sheet at their redemption values. The optional redemption features may become exercisable no earlier than five years from the March 2, 2021 closing date, or upon the occurrence of certain other events. The Company has deemed these interests probable of becoming redeemable in the future and requiring their measurement at the greater of (i) the redemption amount that would be paid if settlement occurred at the balance sheet date, or (ii) the historical value resulting from the original acquisition date fair value plus the impact of any earnings or loss attribution amounts, including dividends. The fair value of the PA Consulting redeemable noncontrolling interest is determined using a combination of the income and market approaches. Under the income approach, fair value is determined by using the projected discounted cash flows of PA Consulting. Under the market approach, the fair value is determined by reference to guideline companies that are reasonably comparable to PA Consulting; the fair value is estimated based on the valuation multiples of earnings before interest, taxes, depreciation and amortization. Further, to the extent redemption values exceed historical values of the interests, changes in redemption amounts are recognized as changes to redeemable noncontrolling interests with an offsetting change in consolidated retained earnings. Additionally, particular to the preference share and in certain circumstances the ordinary share components of redeemable noncontrolling interests, such changes in consolidated retained earnings could also be reflected as a corresponding adjustment to net earnings attributable to Jacobs for purposes of the calculation of consolidated earnings per share attributable to common shareholders. Income Taxes We determine our consolidated income tax expense using the asset and liability method prescribed by U.S. GAAP. Under this method, deferred tax assets and liabilities are recognized for the temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and income tax purposes. Such deferred tax assets and liabilities are adjusted, as appropriate, to reflect changes in tax rates expected to be in effect when the temporary differences reverse. If and when we determine that a deferred tax asset will not be realized for its full amount, we will recognize and record a valuation allowance with a corresponding charge to earnings. Judgment is required in determining our provision for income taxes. In the normal course of business, we may engage in numerous transactions every day for which the ultimate tax outcome (including the period in which the transaction will ultimately be included in taxable income or deducted as an expense) is uncertain. Additionally, we file income, franchise, gross receipts and similar tax returns in many jurisdictions. Our tax returns are subject to audit and investigation by the Internal Revenue Service, most states in the U.S., and by various government agencies representing many jurisdictions outside the U.S. The Tax Cuts and Jobs Act of 2017 (the "Tax Act") contains a provision which subjects a U.S. parent of a foreign subsidiary to current U.S. tax on its global intangible low–taxed income (“GILTI”). The GILTI income is eligible for a deduction, which lowers the effective tax rate of GILTI to 10.5% for calendar years 2018 through 2025 and 13.125% after 2025. The Company will report the tax impact of GILTI as a period cost when incurred. Accordingly, the Company is not providing deferred taxes for basis differences expected to reverse as GILTI. Contractual Guarantees, Litigation, Investigations and Insurance In the normal course of business, we are subject to certain contractual guarantees and litigation. 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. We perform an analysis to determine the level of reserves to establish for both 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 Statements of Earnings. In addition, as a contractor providing services to various agencies of the U.S. federal government, we are subject to many levels of audits, investigations, and claims by, or on behalf of, the U.S. federal government with respect to contract performance, pricing, costs, cost allocations and procurement practices. We adjust revenues based upon the amounts we expect to realize considering the effects of any client audits or governmental investigations. Business Combinations U.S. GAAP requires that the purchase price paid for business combinations accounted for using the acquisition method be allocated to the assets and liabilities acquired based on their respective fair values. The Company makes certain estimates and judgments relating to other assets and liabilities acquired as well as any identifiable intangible assets acquired. 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. New Accounting Pronouncements ASU 2025-05, Financial Instruments—Credit Losses, (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, provides all entities with a practical expedient option when estimating expected credit losses for current accounts receivable and current contract assets arising from transactions accounted for under Topic 606.

| Earnings Per Share and Certain Related Information | Earnings Per Share and Certain Related Information Basic and Diluted Earnings Per Share 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. The following table reconciles the numerator and denominator used to compute basic EPS to the denominator used to compute diluted EPS for the years ended September 26, 2025, September 27, 2024 and September 29, 2023 (in thousands):

Deferred taxes reflect the tax effects of temporary differences between the amounts recorded as assets and liabilities for financial reporting purposes and the comparable amounts recorded for income tax purposes. Deferred tax assets and liabilities are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The following table presents the components of our net deferred tax (liabilities) assets at September 26, 2025 and September 27, 2024 (in thousands):
(1) Prior period amounts have been reclassified to conform with the current period presentation Valuation allowances are recorded to reduce deferred tax assets to the amount that is more likely than not to be realized based on an assessment of positive and negative evidence, including estimates of future taxable income necessary to realize future deductible amounts. The Company's total valuation allowances were $193.1 million and $217.4 million at September 26, 2025 and September 27, 2024, respectively. This change in the valuation allowances is primarily attributable to a $24.2 million decrease resulting from the expiration and other adjustments of certain net operating losses and foreign tax credits and an offsetting elimination of their related valuation allowances. At September 26, 2025 and September 27, 2024, the Company's U.S. and international net operating loss carryforwards totaled $732.4 million and $915.6 million, resulting in a net operating loss deferred tax asset of $207.4 million and $259.3 million, respectively. The Company's net operating losses have various expiration periods between 2026 and indefinite periods. At September 26, 2025, the Company has foreign tax credit carryforwards of $39.0 million (which has a partial valuation allowance of $22.4 million) with $5.8 million expected to expire in 2026 and the remaining by 2033. The following table reconciles total income tax expense from continuing operations using the statutory U.S. federal income tax rate to the consolidated income tax expense for continuing operations shown in the accompanying Consolidated Statements of Earnings for the years ended September 26, 2025, September 27, 2024 and September 29, 2023 (dollars in thousands):
Note: Certain amounts have been reclassified to conform to the current year presentation. The following table presents the components of our consolidated earnings from continuing operations before taxes for the years ended September 26, 2025, September 27, 2024 and September 29, 2023 (in thousands):
We do not record a deferred tax liability for unremitted earnings of our foreign subsidiaries to the extent that the earnings meet the indefinite reversal criteria. The decision as to the amount of unremitted earnings that we intend to maintain in non-U.S. subsidiaries considers items including, but not limited to, forecasts and budgets of financial needs of cash for working capital, liquidity plans, and expected cash requirements in the U.S. As of September 26, 2025, we had not recognized a deferred tax liability on approximately $191.1 million of undistributed earnings for certain foreign subsidiaries, because these earnings are intended to be indefinitely reinvested. If such earnings were distributed, some countries may impose additional taxes. 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 Act, modifications to the international tax framework and pre-Tax Act 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 most relevant impact to the Company for fiscal 2025 is the 100% bonus depreciation for qualified property placed in service after January 19, 2025. The Company is currently assessing its impact on the consolidated financial statements for the provisions that will be effective in future periods. In December 2021, the Organization for Economic Cooperation and Development ("OEC") 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 fiscal year ended 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 Company accounts for unrecognized tax benefits in accordance with ASC Topic 740, Income Taxes. It accounts for interest and penalties on unrecognized tax benefits as interest and penalties reported above the line (i.e., not as part of income tax expense). The primary driver of the current year increase relates to uncertain tax positions on research and development credits and accrued liabilities, which is partially offset by the release of uncertain tax positions for which the statute of limitations expired or resolved through settlement during FY25. At September 26, 2025 and September 27, 2024, if recognized, $41.1 million and $27.1 million, respectively, would affect the Company’s consolidated effective income tax rate. The Company had $26.7 million and $22.6 million in accrued interest and penalties at September 26, 2025 and September 27, 2024, respectively. The Company estimates that, within twelve months, we may realize a decrease in our uncertain tax positions of approximately $6.6 million as a result of concluding various tax audits and closing tax years. 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 taxing authorities worldwide, including such major jurisdictions as Australia, Canada, India, the United Kingdom, and the United States. As of September 26, 2025, the Company has certain U.S. tax returns open to audit in 2019 and 2021 through 2024. For jurisdictions outside the U.S., primarily UK and Australia, various tax returns remain open for audit for the years 2018 through 2024. Although the Company believes the reserves established for the tax positions are reasonable, the outcome of tax audits could be materially different, both favorably and unfavorably. The following table presents the reconciliation of the beginning and ending amount of unrecognized tax benefits, for continuing operations, for the years ended September 26, 2025, September 27, 2024 and September 29, 2023 (in thousands):

| Joint Ventures, VIEs and Other Investments | Joint Ventures, VIEs and Other Investments For consolidated joint ventures, the entire amount of the revenue recognized for services performed and the costs associated with these services, including the services provided by the other joint venture partners, are included in the Company's results of operations. Likewise, the entire amount of each of the assets and liabilities are included in the Company’s consolidated balance sheet. There are no consolidated VIEs that have debt or credit facilities. Summary financial information of consolidated VIEs is as follows (in millions):
Unconsolidated joint ventures are accounted for under the equity method or proportionate consolidation. Proportionate consolidation is used for joint ventures that include unincorporated legal entities and activities of the joint venture are construction-related. For those joint ventures accounted for under proportionate consolidation, only the Company’s pro rata share of assets, liabilities, revenue, and costs are included in the Company’s balance sheet and results of operations. For the proportionate consolidated VIEs, the carrying value of assets and liabilities was $143.9 million and $131.9 million as of September 26, 2025, respectively, and $138.8 million and $138.0 million as of September 27, 2024, respectively. For those joint ventures accounted for under the equity method, the Company's investment balances for the joint venture is included in other noncurrent assets: miscellaneous on the balance sheet and the Company’s pro rata share of net income is included in revenue. In limited cases, there are basis differences between the equity in the joint venture and Jacobs' investment created when Jacobs purchased their share of the joint venture. These basis differences are amortized based on an internal allocation to underlying net assets, excluding allocations to goodwill. Our investments in equity method joint ventures on the Consolidated Balance Sheets as of September 26, 2025 and September 27, 2024 were a net asset of $36.3 million and $36.6 million, respectively. During the years ended September 26, 2025, September 27, 2024, and September 29, 2023, we recognized income from equity method joint ventures of $8.8 million, $11.9 million, and $3.1 million, respectively. Accounts receivable from unconsolidated joint ventures accounted for under the equity method is $13.6 million and $12.3 million as of September 26, 2025 and September 27, 2024, respectively.

| Borrowings | Borrowings The following table presents certain information regarding the Company’s long-term debt at September 26, 2025 and September 27, 2024 (dollars in thousands):
(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 September 26, 2025 and September 27, 2024 were approximately 5.37% 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 September 26, 2025. (2)The U.S. dollar denominated borrowings under the 2021 Term Loan 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 Debit 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 were approximately 6.52%. Borrowings denominated in British pounds bore 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 September 26, 2025 were approximately 5.42% for borrowings denominated in U.S. dollars and 4.97% 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 September 26, 2025, the fair value of the 5.9% Bonds and the 6.35% Bonds is estimated to be $527.6 million and $633.3 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 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. We were in compliance with the covenants under the Revolving Credit Facility and 2025 Term Loan Facility at September 26, 2025. 5.90% Bonds, due 2033 On February 16, 2023, JEGI completed an offering of $500 million aggregate principal amount of 5.90% Bonds due 2033 (the “5.90% Bonds”). The 5.90% Bonds are fully and unconditionally guaranteed by the Company (the "5.90% Bond Guarantee”). The 5.90% Bonds and the 5.90% Bonds Guarantee were offered pursuant to a prospectus supplement, dated February 13, 2023, to the prospectus dated February 6, 2023, that forms a part of the Company's and JEGI’s automatic shelf registration statement on Form S-3ASR previously filed with the SEC, and were issued pursuant to an Indenture, dated as of February 16, 2023, between JEGI, as issuer, the Company, as guarantor, and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”), as amended and supplemented by the First Supplemental Indenture, dated as of February 16, 2023 (the “First Supplemental Indenture”). Interest on the 5.90% Bonds is payable semi-annually in arrears on each March 1 and September 1, until maturity. The 5.90% Bonds bear interest at 5.9% per annum, subject to adjustments as discussed in note (4) to the table above. Prior to December 1, 2032 (the “5.90% Bonds Par Call Date”), JEGI may redeem the 5.90% Bonds at its option, in whole or in part, at any time and from time to time, at the redemption price calculated by JEGI (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of: (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest on the 5.90% Bonds being redeemed, assuming that such 5.90% Bonds matured on the 5.90% Bonds Par Call Date, discounted to the redemption date on a semiannual basis (assuming a 360-day year of twelve 30-day months), at the Treasury Rate (as defined in the First Supplemental Indenture) plus 35 basis points, less (b) interest accrued to the redemption date, and (2) 100% of the principal amount of such 5.90% Bonds to be redeemed, plus, in either case, accrued and unpaid interest on the 5.90% Bonds, if any, to, but excluding, the redemption date. At any time and from time to time on or after the 5.90% Bonds Par Call Date, JEGI may redeem the 5.90% Bonds, at its option, in whole or in part, at a redemption price equal to 100% of the principal amount of the 5.90% Bonds to be redeemed, plus accrued and unpaid interest thereon, if any, up to, but excluding, the redemption date. 6.35% Bonds, due 2028 On August 18, 2023, JEGI completed an offering of $600 million aggregate principal amount of 6.35% Bonds due 2028 (the “6.35% Bonds”). The 6.35% Bonds are fully and unconditionally guaranteed by the Company (the “6.35% Bonds Guarantee”). 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”). Interest on the 6.35% Bonds is payable semi-annually in arrears on each February 18 and August 18, until maturity. The Notes will bear interest at a rate of 6.35% per annum and will mature on August 18, 2028. The 6.35% Bonds bear interest at 6.35% per annum. Prior to July 18, 2028 (the “6.35% Bonds Par Call Date”), JEGI may redeem the 6.35% Bonds at its option, in whole or in part, at any time and from time to time, at the redemption price calculated by JEGI (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of: (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest on the 6.35% Bonds being redeemed, assuming that such 6.35% Bonds matured on the 6.35% Bonds Par Call Date, discounted to the redemption date on a semiannual basis (assuming a 360-day year of twelve 30-day months), at the Treasury Rate (as defined in the Second Supplemental Indenture) plus 30 basis points, less (b) interest accrued to the redemption date, and (2) 100% of the principal amount of such 6.35% Bonds to be redeemed, plus, in either case, accrued and unpaid interest on the 6.35% Bonds, if any, to, but excluding, the redemption date. At any time and from time to time on or after the 6.35% Bonds Par Call Date, JEGI may redeem the 6.35% Bonds, at its option, in whole or in part, at a redemption price equal to 100% of the principal amount of the 6.35% Bonds to be redeemed, plus accrued and unpaid interest thereon, if any, to, but excluding, the redemption date. Other Arrangements The Company has issued $0.3 million in letters of credit under the Revolving Credit Facility, leaving $1.85 billion of available borrowing capacity under the Revolving Credit Facility at September 26, 2025. In addition, the Company had issued $216.7 million under separate, committed and uncommitted letter-of-credit facilities for total issued letters of credit of $217.0 million at September 26, 2025. During fiscal 2020, the Company entered into interest rate and cross currency derivative contracts to swap a portion of our variable rate debt to fixed rate debt. See Note 17- Commitments and Contingencies and Derivative Financial Instruments for discussion regarding the Company's outstanding derivative instruments. The following table presents the amount of interest paid by the Company during September 26, 2025, September 27, 2024 and September 29, 2023 (in thousands):

Total remaining lease payments under the Company's leases for each of the succeeding years is as follows (in thousands):
As of September 26, 2025, we have entered into operating leases that have not yet commenced of approximately $24.2 million. Right-of-Use and Other Long-Lived Asset Impairment During fiscal 2023, as a result of the Company's transformation initiatives, including the changing nature of the Company's use of office space for its workforce, the Company evaluated its existing real estate lease portfolio. These initiatives resulted in the abandonment of certain leased office spaces and the establishment of a formal plan to sublease certain other leased spaces that will no longer be utilized by the Company. In connection with the Company’s actions related to these initiatives, the Company evaluated certain of its lease right-of-use assets and related property, equipment and leasehold improvements for impairment under ASC 360. As a result of the analysis, the Company recognized impairment losses of $46.7 million for the fiscal year September 29, 2023, which are included in in the accompanying Statements of Earnings. The impairment losses recorded include $40.9 million related to right-of-use lease assets and $5.8 million related to other long-lived assets, including property, equipment & improvements and leasehold improvements for the fiscal year ended September 29, 2023. The fair values for the asset groups relating to the impaired long-lived assets were estimated primarily using discounted cash flow models (income approach) with Level 3 inputs. The significant assumptions used in estimating fair value include the expected downtime prior to the commencement of future subleases, projected sublease income over the remaining lease periods and discount rates that reflect the level of risk associated with receiving future cash flows.

| Employee Stock Purchase and Stock Incentive Plans | Employee Stock Purchase and Stock Incentive Plans Employee Stock Purchase Plans Under the Company's stock purchase plans, eligible employees who elect to participate in these plans are granted the right to purchase shares of the common stock of Jacobs at a discount that is limited to 5% of the per-share market value on the day shares are sold to employees. The following table summarizes the stock issuance activity under the plans for the fiscal years ended September 26, 2025, September 27, 2024 and September 29, 2023:
At September 26, 2025, there remains 1,935,700 shares reserved for issuance under the Company's stock purchase plans. Stock Incentive Plans We also sponsor the 2023 Stock Incentive Plan, as amended and restated (the "2023 SIP") and the 1999 Outside Director Stock Plan, as amended and restated (the "1999 ODSP") as well as the StreetLight 2011 Stock Plan (the "StreetLight Plan"). The 2023 SIP provides for the issuance of incentive stock options, non-qualified stock options, share appreciation rights ("SARs"), restricted stock and restricted stock units to employees. The 1999 ODSP provides for awards of shares of common stock, restricted stock, restricted stock units and grants of non-qualified stock options to our outside (i.e., nonemployee) directors. Together the 2023 SIP and 1999 ODSP plans are known as the "Stock Incentive Plans". The StreetLight Plan provides for the issuance of incentive stock options, nonstatutory stock options and restricted stock to employees. The StreetLight Plan is frozen for new awards effective February 4, 2022. The following table sets forth certain information about the Stock Incentive Plans:
Effective September 28, 2012 until January 23, 2023, all grants of shares under the predecessor to the 2023 SIP were issued on a fungible basis. An award other than an option or SAR was granted on a 1.92-to-1.00 basis (“Fungible”). An award of an option or SAR is granted on a 1-to-1 basis (“Not Fungible”). Effective January 24, 2023, at which time the 2023 SIP was adopted, all awards are granted on a 1-to-1 basis. In connection with the Separation Transaction, outstanding awards under the Stock Incentive Plans were converted into adjusted Jacobs awards. The adjustment methodology was designed to preserve the value of the awards immediately before and after the Separation Transaction. The outstanding Jacobs awards will continue to have the same terms and conditions. The modification to the awards did not result in material incremental compensation expense. At September 26, 2025, the amount of compensation cost relating to non-vested awards not yet recognized in the financial statements is approximately $74.4 million. The majority of these unrecognized compensation costs will be recognized by the last quarter of fiscal 2027. The weighted average remaining contractual term of options currently exercisable is 1.9 years. Stock Options The following table summarizes the stock option activity for the years ended September 26, 2025, September 27, 2024 and September 29, 2023:
(1)Represents the additional Jacobs stock options issued as a result of the equitable adjustments. The related exercise prices were also equitably adjusted. Cash received from the exercise of stock options, net of tax remitted, during the year ended September 26, 2025 was $0.9 million. Stock options outstanding at September 26, 2025 consisted of incentive stock options and non-qualified stock options. The following table presents the total intrinsic value of stock options exercised for the fiscal years ended September 26, 2025, September 27, 2024 and September 29, 2023 (in thousands):
The total intrinsic value of stock options exercisable at September 26, 2025 was approximately $6.5 million. The following table presents certain other information regarding our 2023 SIP, 1999 OSDP and StreetLight Plan for the fiscal years ended September 26, 2025, September 27, 2024 and September 29, 2023:
The following table presents certain information regarding stock options outstanding at September 26, 2025:
The 1999 ODSP, the 2023 SIP, and the StreetLight Plan allow participants to satisfy the exercise price of stock options by tendering shares of Jacobs common stock that have been owned by the participants for at least six months. Shares tendered are retired, canceled, and shown as repurchases of common stock in the accompanying Consolidated Statements of Stockholders’ Equity. The weighted average remaining contractual term of options currently exercisable is 5 years. Restricted Stock The following table presents the number of shares of restricted stock and restricted stock units issued as common stock under the 2023 SIP for the years ended September 26, 2025, September 27, 2024 and September 29, 2023:
The amount of restricted stock units issued for awards with performance conditions in the above table are issued based on performance against the target amount. The number of shares ultimately issued, which could be greater or less than target, will be based on achieving specific performance conditions related to the awards as well as achieving the service condition required for the restricted stock units to vest. The following table presents the fair value of shares of the 2023 SIP and the StreetLight Plan (of restricted stock and restricted stock units) vested for the years ended September 26, 2025, September 27, 2024 and September 29, 2023 (in thousands):
The following table presents the number and weighted average grant-date fair value of restricted stock and restricted stock units at September 26, 2025:

The following table presents the number of shares of restricted stock and restricted stock units canceled and withheld for taxes under the 2023 SIP for the years ended September 26, 2025, September 27, 2024 and September 29, 2023:
The amount of unvested restricted stock units canceled for awards with service and performance conditions in the above table is based on the service period achieved and performance against the target amount. The restrictions attached to restricted stock and restricted stock units generally relate to the recipient’s ability to sell or otherwise transfer the stock and stock units. There are also restrictions that subject the stock and stock units to forfeiture back to the Company until earned by the recipient through continued employment or service. The following table provides the number of restricted stock units outstanding at September 26, 2025 under the 2023 SIP.
The following table presents the number of shares of restricted stock and restricted stock units issued under the 1999 ODSP for the years ended September 26, 2025, September 27, 2024 and September 29, 2023:

| Savings and Deferred Compensation Plans | Savings and Deferred Compensation Plans Savings Plans We sponsor various defined contribution savings plans which allow participants to make voluntary contributions by salary deduction. Such plans cover substantially all of our domestic, nonunion employees in the U.S. and are qualified under Section 401(k) of the U.S. Internal Revenue Code. Similar plans outside the U.S. cover various groups of employees of our international subsidiaries and affiliates. Several of these plans allow the Company to match, on a voluntary basis, a portion of the employee contributions. The following table presents the Company’s contributions to these savings plans for the years ended September 26, 2025, September 27, 2024 and September 29, 2023 (in thousands):
Deferred Compensation Plans Our non-qualified deferred compensation programs provide benefits payable to directors, officers, and certain key employees or their designated beneficiaries at specified future dates, upon retirement, or death. The plans are unfunded; therefore, benefits are paid from the general assets of the Company. Participants' cash deferrals earn a return based on the participants' selection of investments in several hypothetical investment options. Participants are also able to defer stock based compensation in the plans, which must remain invested in Company stock and are distributed in shares of Jacobs common stock. Since no investment diversification is permitted, changes in the fair value of Jacobs' common stock are not recognized. For the deferred compensation held in company stock, the number of shares needed to settle the liability is included in the denominator in both the basic and diluted earnings per share calculations. The following table presents the amount charged to (income)/expense for the Company’s deferred compensation plans for the years ended September 26, 2025, September 27, 2024 and September 29, 2023 (in thousands):
The following table presents the amount relating to assets held as deferred compensation arrangement investments for the years ended September 26, 2025 and September 27, 2024 (in thousands):

| Pension and Other Post Retirement Benefit Plans | Pension and Other Post Retirement Benefit Plans Company-Only Sponsored Plans We sponsor various defined benefit pension and other post retirement plans covering employees of certain U.S. and international subsidiaries. The pension plans provide pension benefits that are based on the employee’s compensation and years of service. Our funding policy varies by country and plan according to applicable local funding requirements and plan-specific funding agreements. The accounting for pension and other post retirement benefit plans requires the use of assumptions and estimates in order to calculate periodic benefit cost and the value of the plans’ assets and benefit obligations. These assumptions include discount rates, investment returns, and projected salary increases, among others. The discount rates used in valuing the plans' benefit obligations were determined with reference to high quality corporate and government bonds that are appropriately matched to the duration of each plan's obligations. The expected long-term rate of return on plan assets is generally based on using country-specific simulation models which select a single outcome for expected return based on the target asset allocation. The expected long-term rates of return used in the valuation are the annual average returns generated by these assumptions over a 20-year period for each asset class based on the expected long-term rate of return of the underlying assets. The following table sets forth the changes in the plans’ combined net benefit obligation (segregated between plans existing within and outside the U.S.) for the years ended September 26, 2025 and September 27, 2024 (in thousands):
(1)Actuarial (gains) losses primarily driven by change in discount rates. (2)In fiscal 2024, we completed a termination and buy-out of the primary PA Consulting pension plan which relieves the Company of any future obligations with no impact to net income.

We consider various factors in developing the estimates for the expected, long-term rates of return on plan assets. These factors include the projected, long-term rates of returns on the various types of assets in which the plans invest, as well as historical returns. In general, investment allocations are determined by each plan’s trustees and/or investment committees. The objectives of the plans’ investment policies are to (i) maximize returns while preserving capital; (ii) provide returns sufficient to meet the current and long-term obligations of the plan as the obligations become due; and (iii) maintain a diversified portfolio of assets so as to reduce the risk associated with having a disproportionate amount of the plans’ total assets invested in any one type of asset, issuer or geography. None of our pension plans hold Jacobs common stock directly (although some plans may hold shares indirectly through investments in mutual funds). The plans’ weighted average asset allocations at September 26, 2025 and September 27, 2024 (the measurement dates used in valuing the plans’ assets and liabilities) were as follows:

The service cost component of net periodic pension income is presented in direct cost of contracts and selling, general and administrative expenses while all other components are presented in miscellaneous (expense) income, net on the Consolidated Statements of Earnings for the years presented above. Multiemployer Plans In the U.S. and various other countries, we contribute to trusteed pension plans covering hourly and certain salaried employees under industry-wide agreements. Contributions are based on the hours worked by employees covered under these agreements and are charged to direct cost of contracts on a current basis. With respect to these multiemployer plans, the Company's liability to fund these plans is generally limited to the contributions we are required to make under collective bargaining agreements. Based on our review of our multiemployer pension plans under the guidance provided in ASU 2011-09— Compensation-Retirement Benefits-Multiemployer Plans, we have concluded that none of the multiemployer pension plans into which we contribute are individually significant to our Consolidated Financial Statements. The following table presents the Company’s contributions to these multiemployer plans for the years ended September 26, 2025, September 27, 2024 and September 29, 2023 (in thousands):

| 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)The Company accrued approximately $30.8 million during the fourth quarter of fiscal 2025 as 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. (2)The increase in selling, general and administrative expenses in the year ended September 27, 2024 from September 29, 2023 was primarily related to professional services and other Separation Transaction related expenses of $97.6 million. (3)The decrease in net Earnings from discontinued operations for the year ended September 26, 2025, as compared to September 27, 2024, was primarily driven by prior year operating results of the SpinCo Business, which were divested and therefore are no longer in Company's financial results in fiscal year 2025. Notable components included in our Consolidated Statements of Cash Flows for these discontinued operations are as follows (in thousands):
No assets and liabilities remained held for spin as of September 26, 2025 and September 27, 2024. 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 9- 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 twelve months ended September 26, 2025. Following the distribution, the Company no longer owns any shares of Amentum common stock. The Company reported $(227.3) million and $186.9 million in fair value mark-to-market (losses) gains and other related charges associated with the investment in Amentum shares for the years ended September 26, 2025 and September 27, 2024, respectively, which were included in Miscellaneous (Expense) Income, net as reported in Other (Expense) Income in the Company’s Consolidated Statements 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, provided 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 are expected to be completed by the end of calendar year 2025. 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 $40.5 million in TSA related income for such services that is reported in miscellaneous income (expense) for the year ended September 26, 2025. No services were provided under the TSA for the year ended September 27, 2024. 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 (the “ECR sale”). For the years ended September 26, 2025, September 27, 2024 and September 29, 2023, $2.7 million, $(0.6) million and $(0.8) million, respectively, were reported in Net (Loss) Earnings Attributable to Jacobs from Discontinued Operations on the Consolidated Statement of Earnings related to ECR.

| PA Consulting Redeemable Noncontrolling Interests | PA Consulting Redeemable Noncontrolling Interests In connection with the Company's strategic investment in PA Consulting, 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. PA Consulting is accounted for as a consolidated subsidiary and as a separate operating segment. During fiscal 2025, 2024, and 2023, the Company repurchased certain shares of the redeemable noncontrolling interest holders for $10.4 million, $55.3 million, and $92.9 million respectively, in cash and issued certain shares of redeemable noncontrolling interest holders in fiscal 2024 and 2023 for $19.8 million, and $34.0 million, respectively. 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 71% and 70% of the outstanding ownership of PA Consulting as of September 26, 2025 and September 27, 2024, respectively. For the years ended, 2025 and 2024 there was a $0.0 and $0.10 charge to earnings per share, respectively, 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. Additionally, for the years ended, 2025 and 2024 there was a $0.01 and $0.02 increase in earnings per share, respectively, resulting from redemption value adjustments associated with redeemable noncontrolling interests preference share repurchase and reissuance activities that were recorded. The foregoing results had no impact on the Company’s overall results of operations, financial position or cash flows. See Note 4- Earnings Per Share and Certain Related Information. Changes in the Company's redeemable noncontrolling interests during the fiscal years ended September 26, 2025 and September 27, 2024 were as follows (in thousands):
In addition, certain employees and nonemployees 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, 40% of these grants are subject to time-based vesting and have reached fully vested status as of July 2025. The Company has accrued liabilities associated with the vested grants at fair value in the amounts of $103.8 million and $28.4 million reported in Other deferred liabilities in our Consolidated Balance Sheets as of September 26, 2025 and September 27, 2024, respectively. Also, during the years ended September 26, 2025 and September 27, 2024, the Company recorded approximately $75.3 million and $13.4 million, respectively, in expense associated with these agreements which is reflected in selling, general and administrative expenses in the consolidated statements of earnings. As of September 26, 2025, there was approximately $142.1 million of total unrecognized compensation cost related to the remaining 60% of fair value of such grants anticipated to vest upon a liquidity event, as defined in the applicable agreements. This cost is expected to be recognized in Selling, general and administrative expenses when such a liquidity event is considered probable, which could occur in 2026. Restricted Cash The Company, through its investment in PA Consulting, held $1.4 million and $2.1 million at September 26, 2025 and September 27, 2024, respectively, in cash that is restricted from general use and is included in prepaid expenses and other current assets on the Consolidated Balance Sheets.

Commitments and Contingencies and Derivative Financial Instruments |
12 Months Ended |
|---|---|
Sep. 26, 2025 | |
| 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 9- Borrowings for further discussion relating to the terms of the 5.90% Bonds. The unrealized net gain on these instruments was $20.9 million and $23.6 million, net of tax, and is included in accumulated other comprehensive loss as of September 26, 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 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. During the fourth quarter of fiscal 2024, in connection with the Separation Transaction, the Company terminated two interest rate swaps with an aggregate notional value of $554.7 million for a realized gain of $35.2 million. This realized gain previously recorded as a component of accumulated other comprehensive loss was recognized in miscellaneous income (expense) in the current period as the related interest payments are no longer expected to occur. As of September 26, 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 September 26, 2025 and September 27, 2024 was $20.5 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 September 26, 2025 and September 27, 2024 was $15.6 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 Australian Dollar, British Pound and other currencies, with notional values of $491.9 million at September 26, 2025 and $827.3 million at September 27, 2024. The length of these contracts currently ranges from to three months. The fair value of the foreign exchange contracts at 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. 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. Letters of Credit At September 26, 2025 and September 27, 2024, the Company had issued and outstanding approximately $217.0 million and $306.2 million, respectively, in LOCs and $2.8 billion and $2.3 billion, respectively, in surety bonds. Of the outstanding LOC amount, $0.3 million has been issued under the Revolving Credit Facility and $216.7 million are issued under separate, committed and uncommitted letter-of-credit facilities.

| Contractual Guarantees, Litigation, Investigations, and Insurance [Abstract] | |
| Contractual Guarantees Litigation Investigations And Insurance | Contractual Guarantees, Litigation, 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 primarily 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. See Note 17- Commitments and Contingencies and Derivative Financial Instruments for more information surrounding LOCs and 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 certain losses, claims and liabilities that occur through the use of various deductibles, limits, and retentions under our insurance programs and utilize a number of internal financing mechanisms for these self-insurance arrangements, including the operation of certain captive insurance entities. 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 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 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 primarily 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 include 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 years ended:

| Cybersecurity Risk Management, Strategy, and Governance [Line Items] | |
| Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block] | We maintain a cybersecurity program, designed to proactively identify, assess, manage, mitigate, and respond to cybersecurity threats. Our Cybersecurity Organization develops, implements, and maintains this program, which is governed by our global cybersecurity policy. The underlying controls of the cybersecurity program are based on recognized best practices and standards for cybersecurity and information technology and is aligned with the National Institute of Standards and Technology (“NIST”) Cybersecurity Framework (“CSF”) and the International Organization for Standardization (“ISO”) 27001 Information Security Management System Requirements. Cybersecurity is an important and integrated part of our enterprise risk management program that identifies, monitors and mitigates business, operational and legal risks. Our cybersecurity risk management process is integrated into our overall risk management process, and shares common methodologies, reporting channels and governance processes that apply across the risk management process to other legal, compliance, strategic, operational and financial risk areas. We regularly assess the threat landscape and take a holistic view of cybersecurity risks, with a layered cybersecurity strategy based on prevention, detection and mitigation. Our cybersecurity program maintains assessment protocols for proactively evaluating potential cybersecurity impacts and risks, supported by incident response procedures. We employ systematic processes to manage cybersecurity risks, including through cybersecurity audits, network interconnectivity reviews, system access controls and monitoring, and data backup and recovery. Our cloud environments undergo continuous assessment, with firewall and backup systems designed to support operational resilience. We employ a Zero Trust Security framework that requires identity verification for network access, complemented by regular system assessments and monitoring. Our security controls include identity management programs, data loss prevention protocols, and threat detection capabilities. Our controls undergo regular review and updates based on threat intelligence, ensuring adaptability to emerging threats. Similarly, our incident response program is regularly tested and updated to address emerging threat landscapes. To ensure organization-wide security awareness, cybersecurity training is mandatory and provided to all employees annually. Cybersecurity awareness is also included across other training programs, including our annual "Living our Values" training modules and our privacy training programs. Third-party risk management is a critical component of our cybersecurity strategy. We maintain oversight of service providers through proactive monitoring, leveraging a cybersecurity questionnaire and security and privacy addenda to our contracts where applicable. We evaluate third party providers to ensure they maintain effective security management programs, compliance with information handling and asset management protocols, and provide prompt notification of any known or suspected cybersecurity incidents. To validate our security posture, we engage independent external firms to conduct regular penetration testing, security audits, and cybersecurity consulting. We maintain ISO/IEC 27001 certification for our global enterprise. We also maintain a Cybersecurity Maturity Model Certification (CMMC) L2 certification for our U.S. Federal operations, and Cyber Essentials (CE) Plus certification for our U.K. operations. Additionally, our IT General Controls (ITGCs) undergo annual testing through Sarbanes-Oxley (SOX) audits, which examine security controls relating to system changes, access management, system configurations, and data backup processes. Our operations are subject to cybersecurity risks, including unauthorized access, system failures, and breaches that could originate from both internal networks and through third-party suppliers and service providers. While we have not experienced a material impact on our business strategy, results of operations and/or financial condition from cybersecurity threats or prior incidents, such events have the potential to have a material adverse effect on such aspects of our business. Realization of these risks could damage or disrupt access to our information systems or networks, compromise confidential or protected information, destroy or corrupt data or otherwise interfere with our operations. We continuously monitor our networks for unauthorized access attempts and maintain a range of defensive measures. However, the evolving and sophisticated nature of cyber threats means we cannot guarantee prevention of all potential incidents that could materially impact our business operations, financial condition, or strategic objectives. In addition, even if we effectively defend our own systems, we rely on third-party providers of products, services and networks, with whom we share data and services, and who may themselves be unable to prevent or mitigate cyberattacks.

| Accounting Policies [Abstract] | |
| Revenue Accounting For Contracts | Revenue Accounting for Contracts Engineering, Procurement & Construction Contracts, Service Contracts and Software Contracts The Company recognizes engineering, procurement, and construction contract revenue over time, as performance obligations are satisfied, due to the continuous transfer of control to the customer in accordance with ASC Topic 606, Revenue from Contracts with Customers. Contracts which include engineering, procurement and construction services are generally accounted for as a single deliverable (a single performance obligation). In some instances, the Company’s services associated with a construction activity are limited to specific tasks such as customer support, consulting or supervisory services. In these instances, the services are typically identified as separate performance obligations. The Company recognizes revenue using the percentage-of-completion method, based primarily on contract costs incurred to date compared to total estimated contract costs. Estimated contract costs include the Company’s latest estimates using judgments with respect to labor hours and costs, materials, and subcontractor costs. The percentage-of-completion method (an input method) is the most representative depiction of the Company’s performance because it directly measures the value of the services transferred to the customer. Subcontractor materials, labor and equipment and, in certain cases, customer-furnished materials and labor and equipment are included in revenue and cost of revenue when management believes that the company is acting as a principal rather than as an agent (e.g., the company significantly integrates the materials, labor and equipment into the deliverables promised to the customer or is otherwise primarily responsible for fulfillment and acceptability of the materials, labor and/or equipment). The Company recognizes revenue, but not profit, on certain uninstalled materials that are not specifically produced, fabricated, or constructed for a project. Changes to total estimated contract cost or losses, if any, are recognized in the period in which they are determined as assessed at the contract level. Pre-contract costs are expensed as incurred unless they are expected to be recovered from the client. Project mobilization costs are generally charged to project costs as incurred when they are an integrated part of the performance obligation being transferred to the client. Under the typical payment terms of our engineering, procurement and construction contracts, amounts are billed as work progresses in accordance with agreed-upon contractual terms at periodic intervals (e.g., biweekly or monthly) and customer payments are typically due within 30 to 60 days of billing, depending on the contract. For service contracts, the Company recognizes revenue over time using the cost-to-cost percentage-of-completion method. For contracts with multiple performance obligations, the Company allocates the transaction price to each performance obligation using an estimate of the stand-alone selling price of each distinct service in the contract. In some instances where the Company is standing ready to provide services, the Company recognizes revenue ratably over the service period. When the Company has operations and maintenance or secondment contracts that do not contain variable consideration or have significant timing differences between cash payment and performance, the practical expedient method is applied for revenue recognition. Under the typical payment terms of our service contracts, amounts are billed as work progresses in accordance with agreed-upon contractual terms, and customer payments are typically due within 30 to 60 days of billing, depending on the contract. Revenue for certain contracts related to the sale of software licenses is recognized at a point in time, typically at the time of delivery, in accordance with ASC 606. The software license sale will be treated as a performance obligation separate and distinct from any related service and maintenance. Direct cost of contracts include all costs incurred in connection with and directly for the benefit of client contracts, including depreciation and amortization relating to assets used in providing the services required by the related projects. The level of direct cost of contracts may fluctuate between reporting periods due to a variety of factors, including the amount of pass-through costs we incur during a period. On those projects where we are acting as principal for subcontract labor or third-party materials and equipment, we reflect the amounts of such items in both revenues and costs (and we refer to such costs as “pass-through costs”). Back charges to suppliers or subcontractors are recognized as a reduction of cost when it is determined that recovery of such cost is probable, and the amounts can be reliably estimated. Disputed back charges are recognized when the same requirements described above have been satisfied. Variable Consideration The nature of the Company’s contracts gives rise to several types of variable consideration, including claims and unpriced change orders; awards and incentive fees; and liquidated damages and penalties. The Company recognizes revenue for variable consideration when it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. The Company estimates the amount of revenue to be recognized on variable consideration using the expected value (i.e., the sum of a probability-weighted amount) or the most likely amount method, whichever is expected to better predict the amount. Factors considered in determining whether revenue associated with claims (including change orders in dispute and unapproved change orders in regard to both scope and price) should be recognized include the following: (a) the contract or other evidence provides a legal basis for the claim, (b) additional costs were caused by circumstances that were unforeseen at the contract date and not the result of deficiencies in the company’s performance, (c) claim-related costs are identifiable and considered reasonable in view of the work performed, and (d) evidence supporting the claim is objective and verifiable. If the requirements for recognizing revenue for claims or unapproved change orders are met, revenue is recorded only when the costs associated with the claims or unapproved change orders have been incurred and only up to the amount of consideration that is probable of not being reversed. The Company generally provides limited warranties for work performed under its engineering and construction contracts. The warranty periods typically extend for a limited duration following substantial completion of the Company’s work on the project. Historically, warranty claims have not resulted in material costs incurred for which the Company was not compensated for by the customer. See Note 3- Revenue Accounting for Contracts for further discussion. Joint Ventures and VIEs As is common to the industry, we execute certain contracts jointly with third parties through various forms of joint ventures. Although the joint ventures own and hold the contracts with the clients, the services required by the contracts are typically performed by us and our joint venture partners, or by other subcontractors under subcontracting agreements with the joint ventures. Many of these joint ventures are formed for a specific project. The assets of our joint ventures generally consist almost entirely of cash and receivables (representing amounts due from clients), and the liabilities of our joint ventures generally consist almost entirely of amounts due to the joint venture partners (for services provided by the partners to the joint ventures under their individual subcontracts) and other subcontractors. In general, at any given time, the equity of our joint ventures represents the undistributed profits earned on contracts the joint ventures hold with clients. Very few of our joint ventures have employees or third-party debt or credit facilities. The debt held by the joint ventures is non-recourse to the general credit of Jacobs. The assets of a joint venture are available for use for the obligations of the particular joint venture and not for general operations of the Company. Our risk of loss on these arrangements is usually shared with our partners. The liability of each partner is usually joint and several, which means that each partner may become liable for the entire risk of loss on the project. Furthermore, on some of our projects, the Company has granted guarantees which may encumber both our contracting subsidiary company and the Company for the entire risk of loss on the project. The Company is unable to estimate the maximum potential amount of future payments that we could be required to make under outstanding performance guarantees related to joint venture projects due to a number of factors, including but not limited to, the nature and extent of any contractual defaults by our joint venture partners, resource availability, potential performance delays caused by the defaults, the location of the projects, and the terms of the related contracts. See Note 18- Contractual Guarantees, Litigation, Investigations and Insurance for further discussion. Most of the joint ventures are deemed to be variable interest entities (“VIE”) because they lack sufficient equity to finance the activities of the joint venture. The Company uses a qualitative approach to determine if the Company is the primary beneficiary of the VIE, which considers factors that indicate a party has the power to direct the activities that most significantly impact the joint venture’s economic performance. These factors include the composition of the governing board, how board decisions are approved, the powers granted to the operational manager(s) and partner that holds that position(s), and to a certain extent, the partner’s economic interest in the joint venture. The Company analyzes each joint venture initially to determine if it should be consolidated or unconsolidated. •Consolidated if the Company is the primary beneficiary of a VIE or holds the majority of voting interests of a non-VIE (and no significant participative rights are available to the other partners). •Unconsolidated if the Company is not the primary beneficiary of a VIE or does not hold the majority of voting interest of a non-VIE. Our unconsolidated joint ventures (including equity method investments) are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment might not be recoverable, and impairment losses are recognized for such investments if there is a decline in fair value below carrying value that is considered to be other-than-temporary.

| Fair Value Measurements | 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. 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 9- Borrowings for a discussion of the fair value of long-term debt. Certain other assets and liabilities, such as forward contracts and interest rate swap agreements we purchased as cash-flow hedges discussed in Note 17- Commitments and Contingencies and Derivative Financial Instruments and the Company's investment in Amentum ordinary shares discussed in Note 14- Discontinued Operations are required to be carried in our Consolidated Financial Statements at Fair Value. The fair value of the Company’s reporting units (when a quantitative impairment analysis is required for the purpose of determining whether there is an impairment of the carrying value of goodwill) is determined using an income and market approach. Both approaches require us to make certain estimates and judgments. Under the income approach, fair value is determined by using the discounted cash flows of our reporting units. Under the market approach, the fair values of our reporting units are determined by reference to guideline companies that are reasonably comparable to our reporting units; the fair values are estimated based on the valuation multiples of earnings before taxes, interest, depreciation and amortization associated with the guideline companies. In assessing whether the carrying value of goodwill has been impaired, we utilize the results of both valuation techniques and consider the range of fair values indicated. With respect to equity-based compensation (i.e., share-based payments), we estimate the fair value of stock options granted to employees and directors using the Black-Scholes option-pricing model. Like all option-pricing models, the Black-Scholes model requires the use of subjective assumptions including (i) the expected volatility of the market price of the underlying stock, and (ii) the expected term of the award, among others. Accordingly, changes in assumptions and any subsequent adjustments to those assumptions can cause different fair values to be assigned to our future stock option awards. For restricted stock awards (including restricted stock units) containing service and performance conditions, fair value is based on the closing stock price on the date of grant, adjusted for the expected level of achievement for any performance conditions. The fair values of the assets owned by the various pension plans that the Company sponsors are determined based on the type of asset, consistent with U.S. GAAP. Equity securities are valued by using market observable data such as quoted prices. Publicly traded corporate equity securities are valued at the last reported sale price on the last business day of the year. Securities not traded on the last business day are valued at the last reported bid price. Fixed income investment funds categorized as Level 2 are valued by the trustee using pricing models that use verifiable observable market data (e.g., interest rates and yield curves observable at commonly quoted intervals), bids provided by brokers or dealers, or quoted prices of securities with similar characteristics. Real estate consists primarily of common or collective trusts, with underlying investments in real estate. These investments are valued using the best information available, including quoted market price, market prices for similar assets when available, internal cash flow estimates discounted at an appropriate interest rate, or independent appraisals, as appropriate. Management values insurance contracts and hedge funds using actuarial assumptions and certain values reported by fund managers. Fair value measurements relating to our business combinations are made primarily using Level 3 inputs including discounted cash flow and to the extent applicable, Monte Carlo simulation techniques. Fair value for the identified intangible assets is generally estimated using inputs primarily for the income approach using the multiple period excess earnings method and the relief from royalties method. The significant assumptions used in estimating fair value include (i) revenue projections of the business, including profitability, (ii) attrition rates and (iii) the estimated discount rate that reflects the level of risk associated with receiving future cash flows. Other personal property assets, such as furniture, fixtures and equipment, are valued using the cost approach, which is based on replacement or reproduction costs of the asset less depreciation. The fair value of the contingent consideration is estimated using a Monte Carlo simulation and the significant assumptions used include projections of revenues and probabilities of meeting those projections. Key inputs to the valuation of the noncontrolling interests include projected cash flows and the expected volatility associated with those cash flows. The fair values for the asset groups relating to the impairment assessment of long-lived assets (see Note 10- Leases) were estimated primarily using discounted cash flow models (income approach) with Level 3 inputs. The significant assumptions used in estimating fair value include the expected downtime prior to the commencement of future subleases, projected sublease income over the remaining lease periods and discount rates that reflects the level of risk associated with receiving future cash flows. The methodologies described above and elsewhere in these Notes to Consolidated Financial Statements may produce a fair value measure that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes Level 3 valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement.

| Cash Equivalents | Cash Equivalents We consider all highly liquid investments with original maturities of less than three months to be cash equivalents.
|
| Receivables, Contract Assets and Contract Liabilities | Receivables, Contract Assets and Contract Liabilities Receivables include amounts billed, net and unbilled receivables. Amounts billed, net consist of amounts invoiced to clients in accordance with the terms of our client contracts and are shown net of an allowance for expected credit losses. We anticipate that substantially all of such billed amounts will be collected over the next twelve months. Unbilled receivables and other, which represent an unconditional right to payment subject only to the passage of time in connection with our client contracts, are reclassified to amounts billed when they are billed under the terms of the contract. 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 provided ahead 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. Contract liabilities represent amounts billed to clients in excess of revenue recognized to date. Amounts will be earned based on achievement of deliverables.
|
| Property, Equipment and Improvements | Property, Equipment, and Improvements Property, equipment and improvements are carried at cost, and are shown net of accumulated depreciation and amortization in the accompanying Consolidated Balance Sheets. Depreciation and amortization are computed primarily by using the straight-line method over the estimated useful lives of the assets. The cost of leasehold improvements is amortized using the straight-line method over the lesser of the estimated useful life of the asset or the remaining term of the related lease.
|
| Goodwill and Other Intangible Assets | Goodwill and Other Intangible Assets Goodwill represents the excess of the cost of an acquired business over the fair value of the net tangible and intangible assets acquired. Goodwill and intangible assets with indefinite lives are not amortized; instead, on an annual basis we test goodwill and intangible assets with indefinite lives for possible impairment. Intangible assets with finite lives are amortized on a straight-line basis over the useful lives of those assets. For purposes of impairment testing, goodwill is assigned to the applicable reporting units based on the current reporting structure. We have determined that our operating segments are also our reporting units based on management’s conclusion that the components comprising each of our operating segments share similar economic characteristics and meet the aggregation criteria in accordance with ASC 350. We perform our annual goodwill impairment assessment as of the first day of the fourth fiscal quarter each year. We begin with the qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying value before applying the quantitative assessment described below. If it is determined through the evaluation of events or circumstances that the carrying value may not be recoverable, the Company then compares the fair value of the related reporting unit with its carrying amount. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized. For the 2025 fiscal year, we determined that the fair values of reporting units significantly exceeded their carrying values and an analysis beyond the qualitative level was not considered necessary.
|
| Impairment of Long-Lived Assets | Impairment of Long-Lived Assets Our long-lived assets other than goodwill principally consist of right-of-use (ROU) lease assets, property, equipment and improvements, and finite-lived intangible assets. These long-lived assets are evaluated for impairment for each of our asset groups in accordance with ASC 360 by first identifying whether indicators of impairment exist. If such indicators are present, we assess long-lived asset groups for recoverability based on estimated future undiscounted cash flows. For asset groups where the recoverability test fails, the fair value of each asset group is then estimated and compared to its carrying amount. An impairment loss is recognized for the amount by which an asset group’s carrying value exceeds its fair value.
|
| Foreign Currencies | Foreign Currencies In preparing our Consolidated Financial Statements, it is necessary to translate the financial statements of our subsidiaries operating outside the U.S., which are denominated in currencies other than the U.S. dollar, into the U.S. dollar. In accordance with U.S. GAAP, revenues and expenses of operations outside the U.S. are translated into U.S. dollars using weighted-average exchange rates for the applicable periods being translated while the assets and liabilities of operations outside the U.S. are generally translated into U.S. dollars using period-end exchange rates. The net effect of foreign currency translation adjustments is included in stockholders’ equity as a component of accumulated other comprehensive loss in the accompanying Consolidated Balance Sheets.
|
| Share-based Payments | Share-Based Payments We measure the value of services received from employees and directors in exchange for an award of an equity instrument based on the grant-date fair value of the award. The fair value is recognized as a non-cash cost on a straight-line basis over the period the individual provides services, which is typically the vesting period of the award with the exception of awards containing an internal performance measure, such as Earnings Per Share growth and Return on Invested Capital, which is recognized on a straight-line basis over the vesting period subject to the probability of meeting the performance requirements and adjusted for the number of shares expected to be earned. The cost of these awards is recorded in selling, general and administrative expenses in the accompanying Consolidated Statements of Earnings.
|
| Concentration of Credit Risk | Concentrations of Credit Risk Our cash balances and cash equivalents are maintained in accounts held by major banks and financial institutions located in North America, South America, Europe, the Middle East, India, Australia, Africa and Asia. In the normal course of business, and consistent with industry practices, we grant credit to our clients without requiring collateral. Concentrations of credit risk is the risk that, if we extend a significant amount of credit to clients in a specific geographic area or industry, we may experience disproportionately high levels of default if those clients are adversely affected by factors particular to their geographic area or industry. Concentrations of credit risk relative to trade receivables are limited due to our diverse client base, which includes the U.S. federal government and multi-national corporations operating in a broad range of industries and geographic areas. Additionally, in order to mitigate credit risk, we continually evaluate the credit worthiness of our major commercial clients.
|
| Leases | Leases The Company accounts for its leases in accordance with ASC 842, Leases ("ASC 842"). ASC 842 requires lessees to recognize assets and liabilities for most leases. The Company determines if an arrangement is a lease at contract inception. A lease exists when a contract conveys to the customer the right to control the use of an identified asset for a period of time in exchange for consideration. The definition of a lease embodies two conditions: (1) there is an identified asset in the contract, and (2) the customer has the right to control the use of the identified asset. Lessees are required to classify leases as either finance or operating leases. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. The Company’s right-of use assets and lease liabilities relate to real estate, project assets used in connection with long-term construction contracts, IT assets and vehicles. The Company’s leases have remaining lease terms of less than one year to eighteen years. The Company’s lease obligations are primarily for the use of office space and are primarily operating leases. Certain of the Company’s leases contain renewal, extension, or termination options. The Company assesses each option on an individual basis and will only include options reasonably certain of exercise in the lease term. The Company generally considers the base term to be the term provided in the contract. None of the Company’s lease agreements contain material options to purchase the leased property, material residual value guarantees, or material restrictions or covenants. Long-term project asset and vehicle leases (leases with terms greater than twelve months), along with all real estate and IT asset leases, are recorded on the consolidated balance sheet at the present value of the minimum lease payments not yet paid. Because the Company primarily acts as a lessee and the rates implicit in its leases are not readily determinable, the Company generally uses its incremental borrowing rate on the lease commencement date to calculate the present value of future lease payments. Certain leases include payments that are based solely on an index or rate. These variable lease payments are included in the calculation of the ROU asset and lease liability and are initially measured using the index or rate at the lease commencement date. Other variable lease payments, such as payments based on use and for property taxes, insurance, or common area maintenance that are based on actual assessments are excluded from the ROU asset and lease liability and are expensed as incurred. In addition to the present value of the future lease payments, the calculation of the ROU asset also includes any deferred rent, lease prepayments and initial direct costs of obtaining the lease, such as commissions. Certain lease contracts contain non-lease components such as maintenance and utilities. The Company has made an accounting policy election, as allowed under ASC 842-10-15-37 and discussed above, to capitalize both the lease component and non-lease components of its contracts as a single lease component for all of its right-of-use assets. Short-term project asset and vehicle leases (project asset and vehicle leases with an initial term of twelve months or less or leases that are cancellable by the lessee and lessor without significant penalties) are not recorded on the consolidated balance sheet and are expensed on a straight-line basis over the lease term. The majority of the Company’s short-term leases relate to equipment used on construction projects. These leases are entered into at agreed upon hourly, daily, weekly or monthly rental rates for an unspecified duration and typically have a termination for convenience provision. Such equipment leases are considered short-term in nature unless it is reasonably certain that the equipment will be leased for a term greater than twelve months.
|
| Pensions | Pensions We use certain assumptions and estimates in order to calculate periodic pension cost and the value of the assets and liabilities of our pension plans. These assumptions involve discount rates, investment returns, and projected salary increases, among others. Changes in the actuarial assumptions may have a material effect on the plans’ liabilities and the projected pension expense. We use a corridor approach to amortize actuarial gains and losses. Under this approach, net gains or losses in excess of ten percent of the larger of the pension benefit obligation or the market-related value of the assets are amortized on a straight-line basis. The period of amortization is the average remaining service of active participants who are expected to receive benefits under certain plans and the average remaining future lifetime of plan participants for certain plans. We measure our defined benefit plan assets and obligations as of the end of the month closest to their fiscal year end, which is September 26, 2025 as the alternative measurement date in accordance with FASB guidance ASU 2015-04, Compensation Retirement Benefit (Topic 715): Practical Expedient for the Measurement Date of an Employer’s Defined Benefit Obligation and Plan Asset. This guidance allows employers with fiscal year ends that do not coincide with a calendar month end to make an accounting policy election to measure defined benefit plan assets and obligations as of the end of the month closest to their fiscal year end.
|
| Redeemable Noncontrolling Interests | Redeemable Noncontrolling Interests In connection with the PA Consulting investment in March 2021, the Company recorded redeemable noncontrolling interests, representing the interest holders' initial 35% equity interest in the form of preferred and common shares of PA Consulting. The preferred shares are entitled to a cumulative annual compounding 12% dividend based on the outstanding preferred share subscription price. These noncontrolling interest holders have certain option rights to put the preferred and common share interests back to the Company at a value based on the fair value of PA Consulting (the redemption values). The primary inputs and assumptions impacting the fair value of PA Consulting include projections of revenue and earnings before interest, taxes, depreciation and amortization and discount rates applied thereto. Additionally, the Company has an option to call the interests for certain individual shareholders in certain circumstances. Because the interests are redeemable at the option of the holders and not solely within the control of the Company, the Company classified the interests in redeemable noncontrolling interests within its Consolidated Balance Sheet at their redemption values. The optional redemption features may become exercisable no earlier than five years from the March 2, 2021 closing date, or upon the occurrence of certain other events. The Company has deemed these interests probable of becoming redeemable in the future and requiring their measurement at the greater of (i) the redemption amount that would be paid if settlement occurred at the balance sheet date, or (ii) the historical value resulting from the original acquisition date fair value plus the impact of any earnings or loss attribution amounts, including dividends. The fair value of the PA Consulting redeemable noncontrolling interest is determined using a combination of the income and market approaches. Under the income approach, fair value is determined by using the projected discounted cash flows of PA Consulting. Under the market approach, the fair value is determined by reference to guideline companies that are reasonably comparable to PA Consulting; the fair value is estimated based on the valuation multiples of earnings before interest, taxes, depreciation and amortization. Further, to the extent redemption values exceed historical values of the interests, changes in redemption amounts are recognized as changes to redeemable noncontrolling interests with an offsetting change in consolidated retained earnings. Additionally, particular to the preference share and in certain circumstances the ordinary share components of redeemable noncontrolling interests, such changes in consolidated retained earnings could also be reflected as a corresponding adjustment to net earnings attributable to Jacobs for purposes of the calculation of consolidated earnings per share attributable to common shareholders.
|
| Income Taxes | Income Taxes We determine our consolidated income tax expense using the asset and liability method prescribed by U.S. GAAP. Under this method, deferred tax assets and liabilities are recognized for the temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and income tax purposes. Such deferred tax assets and liabilities are adjusted, as appropriate, to reflect changes in tax rates expected to be in effect when the temporary differences reverse. If and when we determine that a deferred tax asset will not be realized for its full amount, we will recognize and record a valuation allowance with a corresponding charge to earnings. Judgment is required in determining our provision for income taxes. In the normal course of business, we may engage in numerous transactions every day for which the ultimate tax outcome (including the period in which the transaction will ultimately be included in taxable income or deducted as an expense) is uncertain. Additionally, we file income, franchise, gross receipts and similar tax returns in many jurisdictions. Our tax returns are subject to audit and investigation by the Internal Revenue Service, most states in the U.S., and by various government agencies representing many jurisdictions outside the U.S. The Tax Cuts and Jobs Act of 2017 (the "Tax Act") contains a provision which subjects a U.S. parent of a foreign subsidiary to current U.S. tax on its global intangible low–taxed income (“GILTI”). The GILTI income is eligible for a deduction, which lowers the effective tax rate of GILTI to 10.5% for calendar years 2018 through 2025 and 13.125% after 2025. The Company will report the tax impact of GILTI as a period cost when incurred. Accordingly, the Company is not providing deferred taxes for basis differences expected to reverse as GILTI.
|
| Contractual Guarantees, Litigation, Investigations and Insurance | Contractual Guarantees, Litigation, Investigations and Insurance In the normal course of business, we are subject to certain contractual guarantees and litigation. 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. We perform an analysis to determine the level of reserves to establish for both 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 Statements of Earnings. In addition, as a contractor providing services to various agencies of the U.S. federal government, we are subject to many levels of audits, investigations, and claims by, or on behalf of, the U.S. federal government with respect to contract performance, pricing, costs, cost allocations and procurement practices. We adjust revenues based upon the amounts we expect to realize considering the effects of any client audits or governmental investigations.
|
| Business Combinations | Business Combinations U.S. GAAP requires that the purchase price paid for business combinations accounted for using the acquisition method be allocated to the assets and liabilities acquired based on their respective fair values. The Company makes certain estimates and judgments relating to other assets and liabilities acquired as well as any identifiable intangible assets acquired.
|
| 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.
