Accounting Policies [Abstract]  
Summary of Significant Accounting Policies and Basis of Presentation Summary of Significant Accounting Policies and Basis of Presentation
Basis of Presentation and Principles of Consolidation. Historically, our fiscal years have been 52- or 53-week periods ending on the Saturday nearest to October 31. Fiscal 2024 was a 53-week year ended on November 2, 2024, and fiscal 2023 was a 52-week year ended on October 28, 2023.
We have changed our fiscal year end from the Saturday nearest to October 31 and consisting of 52 or 53 fiscal weeks to a fiscal year end of October 31 each year. The fiscal year change became effective with our fiscal 2025, which began on November 3, 2024. Our fiscal quarters end on January 31, April 30, July 31 and October 31 of each year.
Our results of operations for the fiscal 2025, fiscal 2024 and fiscal 2023 included 363 days, 371 days, and 364 days respectively. For presentation purposes, the consolidated financial statements and accompanying notes refer to the closest calendar month end.
The consolidated financial statements include our accounts and the accounts of our wholly and majority-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates. To prepare financial statements in conformity with U.S. GAAP, management must make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates and could have a material impact on our operating results and financial position.
Acquisition of Ansys. On July 17, 2025 (the Acquisition Date), we completed the acquisition of ANSYS, Inc. (Ansys), a provider of broad engineering simulation and analysis software and services for $199.91 in cash and 0.3399 of a share of our common stock in exchange for each ordinary share of Ansys for a total consideration of $34.9 billion.
We accounted for the acquisition of Ansys by applying the acquisition method of accounting for business combinations. The consolidated financial statements include the financial results of Ansys prospectively from the Acquisition Date. See Note 4. Business Combinations and Note 10. Senior Notes, Bridge Commitment Letter, Term Loan and Revolving Credit Facilities of the Notes to Consolidated Financial Statements in this Annual Report.
Cash Equivalents and Short-term Investments. We consider all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents, as well as time deposits which can be withdrawn at any time without penalty to be cash equivalents. Our investments in debt securities with remaining maturities greater than three months at the date of purchase are designated as available-for-sale securities as we may convert these investments into cash at any time to fund general operations, and included in short-term investments in the consolidated balance sheets. Our debt securities generally have an effective maturity term of less than three years and are carried at fair value, with unrealized gains and losses included in the consolidated balance sheets as a component of accumulated other comprehensive income (loss). For available-for-sale debt securities in an unrealized loss position, we evaluate whether a current expected credit loss exists based on available information relevant to the credit rating of the security, current economic conditions and reasonable and supportable forecasts. The allowance for credit loss is recorded in other income (expense), net, in the consolidated statements of income, not to exceed the amount of the unrealized loss. Any excess unrealized loss other than the credit loss is recognized in accumulated other comprehensive income or loss in the stockholders' equity section of the consolidated balance sheets. The cost of securities sold is based on the specific identification method and realized gains and losses are included in other income (expense), net. See Note 8. Financial Assets and Liabilities of the Notes to Consolidated Financial Statements in this Annual Report.
Investments in Equity Securities. We hold equity securities in privately held companies for the promotion of business and strategic objectives. We account for these investments using either the measurement alternative approach when the fair value of the investment is not readily determinable and we do not have the ability to exercise significant influence, or the equity method of accounting when it is determined that we have the ability to exercise significant influence. Investments accounted for using the measurement alternative approach are initially recorded at cost and adjusted for changes in fair value from observable transactions. For investments accounted for using the equity method of accounting, we record our proportionate share of the investee’s income or loss to other income (expense), net, in our consolidated statements of income. These investments are subject to a periodic impairment review, and are included in other long-term assets in the consolidated balance sheets.
Accounts Receivable, Net. The balances consist of billed accounts receivable and current portion of unbilled accounts receivable. Trade accounts receivables are recorded at the invoiced amount and do not bear interest.
Allowance for Credit Losses. We maintain an allowance for credit losses for expected uncollectible accounts receivable and contract assets, which is recorded as an offset to accounts receivable or contract assets and provisions for credit losses are recorded in general and administrative expense in the consolidated statements of income. The allowance for current expected credit losses is based on a review of customer accounts and considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. The allowance for credit losses is reviewed on a quarterly basis to assess the adequacy of the allowance. The following table presents the changes in the allowance for credit losses:

2023$38,586 $18,345 $(6,565)$50,366 
Inventories. Inventories are computed at standard costs which approximate actual costs, on a first-in, first-out basis and valued at the lower of cost or net realizable value. Inventories primarily include components and finished goods for complex emulation and prototyping hardware systems. The valuation process includes a review of the forecasts based upon future demand and market conditions. Inventory provisions are recorded when gross inventory may be in excess of anticipated demand or considered obsolete. Inventory provisions are impacted by market and economic conditions, technology changes, new product introductions and changes in strategic direction, and require estimates that may include uncertain elements.
Fair Values of Financial Instruments. Our cash equivalents, short-term investments, marketable securities and foreign currency contracts are carried at fair value. The fair value of our accounts receivable and accounts payable approximates the carrying amount due to their short duration. Non-marketable equity securities are accounted for using either the measurement alternative or equity method of accounting. We perform periodic impairment analysis on these non-marketable equity securities. The carrying amount of the short-term and long-term debt approximates the estimated fair value. See Note 9. Fair Value Measurements of the Notes to Consolidated Financial Statements in this Annual Report.
Foreign Currency Contracts. We operate internationally and are exposed to potentially adverse movements in currency exchange rates. We enter into hedges in the form of foreign currency forward contracts to reduce our exposure to foreign currency rate changes on non-functional currency denominated forecasted transactions and balance sheet positions. The assets or liabilities associated with the forward contracts are recorded at fair value in other current assets or accrued liabilities in the consolidated balance sheets.
The accounting for gains and losses resulting from changes in fair value depends on the use of the foreign currency forward contract and whether it is designated and qualifies for hedge accounting. See Note 8. Financial Assets and Liabilities of the Notes to Consolidated Financial Statements in this Annual Report.
Concentration of Credit Risk. Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash equivalents, short-term investments, foreign currency contracts, and trade accounts receivable. We maintain cash equivalents primarily in highly rated taxable and tax-exempt money market funds located in the U.S. and in various overseas locations. Our short-term investments include a variety of financial instruments, such as corporate debt and municipal securities, U.S. Treasury and Government agency securities. By policy, we limit the amount of credit exposure with any one issue, issuer and type of instrument.
We sell our products worldwide primarily to customers in the global electronics market. We perform on-going credit evaluations of our customers’ financial condition and do not require collateral. We establish reserves for potential credit losses and such losses have been within management’s expectations.
Income Taxes. We account for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
We account for uncertainty in income taxes using a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining whether it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. An uncertain tax position is considered effectively settled on completion of an examination by a taxing authority if certain other conditions are satisfied.
Property and Equipment. Property and equipment is recorded at cost less accumulated depreciation. Assets, excluding land, are depreciated using the straight-line method over their estimated useful lives. Depreciation expenses were $171.9 million, $162.9 million and $141.4 million in fiscal 2025, 2024 and 2023, respectively. Repair and maintenance costs are expensed as incurred and such costs were $104.7 million, $89.4 million and $74.4 million in fiscal 2025, 2024 and 2023, respectively.
The useful lives of depreciable assets are as follows:
 Useful Life in Years
Computer and other equipment
3 - 8
Buildings30
Furniture and fixtures5
Leasehold improvements Shorter of the lease term or the estimated useful life
Leases. We determine if an arrangement is a lease at inception of the contract, which is the date on which the terms of the contract are agreed to, and the agreement creates enforceable rights and obligations. A contract is or contains a lease when we have the right to control the use of an identified asset for a period of time. The commencement date of the lease is the date that the lessor makes an underlying asset available for use by the lessee. On the commencement date, leases are evaluated for classification and assets and liabilities are recognized based on the present value of lease payments over the lease term.
The lease term used to calculate the lease liability includes options to extend or terminate the lease when it is reasonably certain that the option will be exercised. The right of use (ROU) asset is initially measured as the amount of lease liability, adjusted for any initial lease costs, prepaid lease payments and any lease incentives. Variable lease payments, consisting primarily of reimbursement of costs incurred by lessors for common area maintenance, real estate taxes and insurance, are not included in the lease liability and are recognized as they are incurred.
As most of our leases do not provide an implicit rate, we use the incremental borrowing rate at lease commencement to measure ROU assets and lease liabilities. We use a benchmark senior unsecured yield curve for debt instruments over the similar term, and consider specific credit quality, market conditions, tenor of lease arrangements, and quality of collateral to determine the incremental borrowing rate.
Operating lease expense is generally recognized on a straight-line basis over the lease term. We have elected the practical expedient to account for the lease and non-lease components as a single lease component for the majority of our asset classes. For leases with an initial term of one year or less, we have elected not to record the ROU asset or liability.
Business Combinations. We allocate the purchase price of acquired companies to the tangible and intangible assets acquired and liabilities assumed based on their acquisition-date fair values with the exception of contract assets and contract liabilities (deferred revenue) which are recognized and measured on the acquisition date in accordance with our “Revenue Recognition” policy, as if we had originated the contracts. The excess of the purchase consideration over the fair value of these identifiable assets and liabilities is recorded as goodwill. Acquisition-related expenses are recognized separately from the business combination and are expensed as incurred. We include the results of operations of the businesses that are acquired from the acquisition date.
Goodwill. Goodwill represents the excess of the aggregate purchase price over the fair value of the net tangible and identifiable intangible assets acquired by us. All goodwill acquired in a business combination is assigned to one or more reporting units as of acquisition date. We have two reportable segments, and reporting units are determined to be the same as reportable segments. The carrying amount of goodwill at each reporting unit is tested for impairment annually on the first day of the fourth fiscal quarter, or more frequently if facts and circumstances warrant a review. We perform either a qualitative or quantitative assessment for goodwill impairment test. When a quantitative goodwill impairment assessment is performed, we use an income approach based on discounted cash flow analysis, a market approach based on market multiples, or a combination of both. If the fair value of a reporting unit is less than its carrying value, a goodwill impairment loss is recorded for the difference.
Intangible Assets. Intangible assets consist of acquired technology, certain contract rights, customer relationships, trademarks and trade names, and capitalized software. These intangible assets are acquired through business combinations, direct purchases, or internally developed capitalized software. Intangible assets are amortized on a straight-line basis over their estimated useful lives which range from one to twenty-three years.
We review the carrying values of long-lived assets including intangible assets whenever events or changes in circumstances indicate that the carrying value may not be fully recoverable. Recoverability of long-lived assets is
measured by comparing the carrying value of such asset group to the future undiscounted cash flows that asset group is expected to generate. If the undiscounted future cash flow is less than the carrying amount of the asset group, we recognize an impairment loss based on the excess of the carrying amount over the fair value of the asset group.
Redeemable Non-controlling Interest. Non-controlling interest that is not solely redeemable within our control is reported as temporary equity in our consolidated balance sheets. The carrying value of the redeemable non-controlling interest equals the redemption value at the end of each reporting period, after giving effect to the change from the net income (loss) attributable to the redeemable non-controlling interest. We remeasure the redemption value of the non-controlling interest on a quarterly basis and changes in the estimated redemption value are recognized through retained earnings and may also impact the net income or loss attributable to common stockholders of Synopsys if the redemption value falls below a stated threshold. See Note 4. Business Combinations of the Notes to Consolidated Financial Statements in this Annual Report for more information regarding the redeemable non-controlling interests.
Revenue Recognition. We recognize revenue for the transfer of services or products to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those services or products. The principle is achieved through the following five-step approach:
Identification of the contract, or contracts, with the customer
Identification of the performance obligation in the contract
Determination of the transaction price 
Allocation of the transaction price to the performance obligations in the contract 
Recognition of revenue when, or as, we satisfy a performance obligation 
Nature of Products and Services
We generate revenue from the licensing of our EDA software, IP products and S&A software solutions, as well as sale of hardware products, and maintenance and services. The various types are set forth below.
Electronic Design Automation
Software license revenue consists of fees associated with the licensing of our software and Ansys semiconductor products primarily through Technology Subscription License (TSL) contracts. TSLs are time-based licenses for a finite term and generally provide the customer with limited rights to receive, or to exchange certain quantities of licensed software for, unspecified future technology. The majority of our arrangements are TSLs due to the nature of our business and customer requirements. In addition to the licenses, the arrangements also include: post-contract customer support, which includes providing frequent updates and upgrades to maintain the utility of the software due to rapid changes in technology; other intertwined services such as multiple copies of the tools; assisting our customers in applying our technology in the customers' development environment; and rights to remix licenses for other licenses. Payments are generally received in equal or near equal installments over the term of the arrangement. We have concluded that our software licenses in TSL contracts are not distinct from our obligation to provide unspecified software updates to the licensed software throughout the license term. Such updates represent inputs to a single, combined performance obligation, commencing upon the later of the arrangement effective date or transfer of control to the software license. Remix rights are not an additional promised good or service in the contract, and where unspecified additional software product rights are part of the contract with the customer, such rights are accounted for as part of the single performance obligation that includes the licenses, updates, and technical support because such rights are provided for the same period of time and have the same pattern of transfer to the customer over the duration of the subscription term. 
Design IP Products
We generally license IP under nonexclusive license agreements that provide usage rights for specific applications. Additionally, for certain IP license agreements, royalties are collected as customers sell their own products that incorporate our IP. These arrangements generally have two distinct performance obligations that consist of transferring the licensed IP and the post contract support service. Support services consist of a stand-ready
obligation to provide technical support and software updates over the support term. Revenue allocated to the IP license is recognized at a point in time upon the later of the delivery date or the beginning of the license period, and revenue allocated to support services is recognized ratably over the support term. Royalties are recognized as revenue is earned, generally when the customer sells its products that incorporate our IP. 
Simulation and Analysis
S&A solutions allow engineers to virtually test and optimize designs across various physics domains, such as structural analysis, thermal analysis, and computational fluid dynamics (CFD). S&A software solutions are offered as subscription solutions and also as perpetual licenses. Software subscription arrangements include bundles of time-based software licenses with support services, which includes rights to technical support and software updates that are provided over the support term and are transferred to the customer over time. In such subscription arrangements, the updates to time-based software licenses are not considered integral to maintaining the utility of the software. We consider the license and support services as separate performance obligations. In these instances, we allocate the total consideration received for the revenue arrangement to the separate performance obligations based on the standalone selling prices of the time-based software license and support service. The time-based software license revenue is presented as upfront products revenue, recognized at a point of time upon the later of the delivery date or the beginning of the license period, and the revenue related to the support service is presented as maintenance and service revenue and is recognized over the term of the arrangement. Perpetual license arrangements typically include a perpetual license sold with support services, which includes a stand-ready obligation to provide technical support and software updates over the support term. We allocate the total consideration received for the bundled perpetual and support service arrangements based on the standalone selling prices of the perpetual license and support service. Revenue from perpetual licenses is presented as upfront product revenue and is recognized at a point in time upon the later of the delivery date or the beginning of the license period. Revenue from support service is classified as maintenance and service revenue and is recognized ratably over the term of the contract, as we satisfy the support service performance obligation.
Hardware
We generally have two performance obligations in arrangements involving the sale of hardware products. The first performance obligation is to transfer the hardware product, which includes embedded software integral to the functionality of the hardware product. The second performance obligation is to provide maintenance on the hardware and our embedded software, including rights to technical support, hardware repairs and software updates that are all provided over the same term and have the same time-based pattern of transfer to the customer. The portion of the transaction price allocated to the hardware product is recognized as revenue at a point in time when control of the hardware is transferred to the customer. We have concluded that control generally transfers upon shipment because the customer has the ability to direct the use of the asset and an obligation to pay for the hardware. The portion of the transaction price allocated to maintenance is recognized as revenue that is ratable over the maintenance term.
Professional Services
Our arrangements often include service elements other than maintenance and support services. These services include training, design assistance, and consulting. These services are generally performed on a time and materials basis, and are recognized over time, as the customer simultaneously receives and consumes the benefit provided. Certain arrangements also include the customization or modification of licensed IP. Revenue from these contracts is recognized over time as the services are performed, when the development is specific to the customer’s needs and we have enforceable rights to payment for performance completed. Inputs such as costs incurred and hours expended are used in order to measure progress of performance. We have a history of accurately estimating project status and the costs necessary to complete projects. A number of internal and external factors can affect these estimates, including labor rates, utilization and efficiency variances, specification and testing requirement changes, and changes in customer delivery priorities. Payments for services are generally due upon milestones in the contract or upon consumption of the hourly resources.
Flexible Spending Accounts
Our customers frequently enter into non-cancelable Flexible Spending Account arrangements (FSA) whereby the customer commits to a fixed dollar amount over a specified period of time that can be used to purchase from a list of our products or services. These arrangements do not meet the definition of a revenue contract until the customer
executes a separate order (pulldown request) to identify the required products and services that they are purchasing. The combination of the FSA arrangement and the subsequent order creates enforceable rights and obligations, thus meeting the definition of a revenue contract. Each separate order under the agreement is treated as an individual contract and accounted for based on the respective performance obligations included within the pulldown requests.
Significant Judgments
Our contracts with customers often include promises to transfer multiple products and services to a customer. Customers can negotiate for a broad portfolio of solutions, and favorable terms along with future purchase options to manage their overall costs. Analysis of the terms and conditions in these contracts and their effect on revenue recognition may require significant judgment. We have concluded that (1) our EDA software licenses in TSL contracts and software licenses in certain Ansys' semiconductor industry subscription products are not distinct from our obligation to provide unspecified software updates to the licensed software throughout the license term, because those promises represent inputs to a single, combined performance obligation, and (2) where unspecified additional software product rights are part of the contract with the customer, such rights are accounted for as part of the single performance obligation that includes the licenses, updates, and technical support, because such rights are provided for the same period of time and have the same time-based pattern of transfer to the customer. In reaching this conclusion, we considered the nature of the obligation to customers, which is to provide an ongoing right to use the most up to date and relevant software. As EDA customers operate in a rapidly changing and competitive environment, satisfying the obligation requires providing critical updates to the existing software products, including ongoing iterative interaction with customers to make the software relevant to customers’ ability to meet the time to go to market with advanced products.
Software subscription arrangements for S&A solutions include bundles of time-based software licenses with support services, which includes rights to technical support and software updates that are provided over the support term and are transferred to the customer over time. We have concluded that the updates to time-based software licenses are not considered integral to maintaining the utility of the software and hence the license and support services as separate performance obligations. We also license S&A software on a perpetual basis with support services, which includes a stand-ready obligation to provide technical support and software updates over the support term. We allocate the total consideration received for the bundled perpetual and support service arrangements based on the standalone selling prices of the perpetual license and support service.
Our contracts with customers can involve hundreds of products and various license rights. Customers often negotiate a broad portfolio of solutions, and favorable terms along with future purchase options to manage their overall costs. Determining whether the purchase options are considered distinct performance obligations that should be accounted for separately as material rights versus combined together may require significant judgment.
Judgment is also required to determine the standalone selling price (SSP) for each distinct performance obligation. For non-software performance obligations (IP, Hardware, and services), SSP is established based on observable prices of products and services sold separately. SSP for license (and related updates and support) in a contract with multiple performance obligations is determined by applying a residual approach whereby all other non-software performance obligations within a contract are first allocated a portion of the transaction price based upon their respective SSP, using observable prices, with any residual amount of the transaction price allocated to the license because we do not sell the license separately, and the pricing is highly variable. For S&A product subscription sales, we use all information reasonably available to us to determine the estimated SSP of time-based software license and support services.
Contract Balances
The timing of revenue recognition may differ from the timing of invoicing customers, resulting in receivables, contract assets, or contract liabilities (deferred revenue) in our consolidated balance sheets. For specific software, hardware, and IP agreements with payment plans, we record an unbilled receivable associated with revenue recognized upon transfer of control, as it holds an unconditional right to invoice and receive payment in the future for those transferred products or services. A contract asset is recorded when revenue is recognized before we have the unconditional right to invoice or retain performance risk concerning that performance obligation. These contract assets transition to receivables when the rights become unconditional, generally upon the completion of a milestone. A deferred revenue is recorded when revenue is recognized subsequent to invoicing.
Warranties and Indemnities
Warranties. We generally warrant our products to be free from defects in media and to substantially conform to material specifications for a period of 90 days for our software products and for up to six months for our hardware products.
Indemnities. In addition to such warranties, in certain cases, we provide our customers with limited indemnification with respect to claims that their use of our software products infringes on patents, copyrights, trademarks or trade secrets. We are unable to estimate the potential impact of these commitments on the future results of operations.
Net Income Per Share. We compute basic net income per share by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net income per share reflects the dilution from potential common shares outstanding such as stock options and unvested restricted stock units (RSUs) and awards during the period using the treasury stock method. See Note 16. Net Income (Loss) Per Share of the Notes to Consolidated Financial Statements in this Annual Report.
Foreign Currency Translation. The functional currency of the majority of our active foreign subsidiaries is the foreign subsidiary’s local currency. Assets and liabilities that are not denominated in the functional currency are remeasured into the functional currency with any related gains or losses recorded in earnings. We translate assets and liabilities of our non-U.S. dollar functional currency foreign operations into the U.S. dollar reporting currency at exchange rates in effect at the balance sheet date. We translate income and expense items of such foreign operations into the U.S. dollar reporting currency at average exchange rates for the period. Accumulated translation adjustments are reported in stockholders’ equity, as a component of accumulated other comprehensive income (loss).
Recently Adopted Accounting Pronouncements
In June 2022, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, which applies to all equity securities measured at fair value that are subject to contractual sale restrictions. This change prohibits entities from taking into account contractual restrictions on the sale of equity securities when estimating fair value and introduces required disclosures for such transactions. We adopted the standard as of the beginning of fiscal 2025 on a prospective basis and the adoption did not have a material impact on our consolidated financial statements.
In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The ASU expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the Chief Operating Decision Maker (CODM) and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. The ASU is effective for our annual reports beginning in fiscal 2025 and interim period reports beginning in fiscal 2026. We adopted the standard during fiscal 2025, on a retrospective basis, and the adoption provided more granular disclosure of significant operating expenses within our segment disclosure. See Note 19. Segment Disclosure of the Notes to Consolidated Financial Statements in this Annual Report for further details.
Recent Accounting Pronouncements Not Yet Adopted
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which enhances the transparency and decision usefulness of income tax disclosures primarily through changes to the rate reconciliation and income taxes paid information. The ASU will be effective for us beginning in fiscal 2026 and will be applied on a prospective basis. Early adoption is permitted. We are currently evaluating the impact of this ASU on our consolidated financial statements and related disclosures.
In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income-Expense Disaggregation (Subtopic 220-40): Disaggregation of Income Statement Expenses. The ASU requires the disclosure of additional information related to certain costs and expenses, including amounts of inventory purchases, employee compensation, and depreciation and amortization included in each income statement line item. The ASU also requires disclosure of the total amount of selling expenses and our definition of selling expenses. The ASU will be effective for our annual reports beginning in fiscal 2028, and interim period reports
beginning in fiscal 2029 either on a prospective or retrospective basis. Early adoption is permitted. We are currently evaluating the impact of adopting this ASU on our consolidated financial statements and related disclosures.
In July 2025, the FASB issued ASU 2025-05, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. The ASU allows companies to apply a practical expedient when estimating credit losses on current accounts receivable and contract assets. The ASU will be effective for us beginning in fiscal 2027 and will be applied on a prospective basis. Early adoption is permitted. We are currently evaluating the impact of adopting this ASU on our consolidated financial statements and related disclosures.
In September 2025, the FASB issued ASU 2025-06, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which modernizes the accounting for internal-use software costs and clarifies the criteria for capitalization. The ASU will be effective for us beginning in fiscal 2029, either on a prospective, retrospective, or a modified basis. Early adoption is permitted. We are currently evaluating the impact of adopting this ASU on our consolidated financial statements and related disclosures.

Discontinued Operations Discontinued Operations
On September 30, 2024, we completed the sale of our former Software Integrity business (the Software Integrity Divestiture) to entities controlled by funds affiliated with Clearlake Capital Group, L.P. and Francisco Partners (together, the Sponsors). The aggregate consideration for the sale was $1.65 billion, comprised of (i) cash of $1.48 billion received upon closing; (ii) $121.5 million reflecting the present value of $125.0 million in deferred consideration receivable in equal installments over five fiscal quarters beginning on January 17, 2025, subject to acceleration at our option prior to the closing of the Ansys Merger; (iii) $22.2 million reflecting the fair value of contingent consideration of up to $475.0 million receivable upon the Sponsors achieving a specified rate of return in the event of one or more potential liquidity transactions; and (iv) additional consideration receivable of $27.1 million as a result of net working capital adjustments. As a result of the Software Integrity Divestiture, we derecognized net assets of $720.5 million and incurred transaction costs of $61.7 million, resulting in a pre-tax gain of $868.8 million in fiscal 2024.
In the second quarter of fiscal 2025, we finalized the working capital adjustments and received $20.0 million from the Sponsors. The remainder receivable balance of $7.1 million was recorded as a reduction to the previously recorded gain from the Software Integrity Divestiture.

Fiscal 2025
On July 17, 2025, we completed our acquisition of Ansys pursuant to the terms of the previously announced Agreement and Plan of Merger, dated as of January 15, 2024 (the Merger Agreement) by and among Synopsys, Ansys and ALTA Acquisition Corp. (Merger Sub), a Delaware corporation and a wholly owned subsidiary of Synopsys. Pursuant to the Merger Agreement, Merger Sub merged with and into Ansys (the Ansys Merger), with Ansys surviving the Ansys Merger as a wholly owned subsidiary of Synopsys. At the effective time of the Ansys Merger (the Effective Time), each share of common stock, par value $0.01 per share, of Ansys (Ansys Common Stock) issued and outstanding immediately prior to the Effective Time (subject to certain exceptions) was converted into the right to receive (i) 0.3399 (the Exchange Ratio) of a share of common stock, par value $0.01 per share, of Synopsys (Synopsys Common Stock) (in the aggregate, the Stock Consideration) and (ii) $199.91 in cash, without interest (the Per Share Cash Amount, and in the aggregate, the Cash Consideration) (the Stock Consideration and the Cash Consideration, collectively, the Merger Consideration). In addition, we assumed certain outstanding Ansys options and other outstanding unvested Ansys equity awards held by continuing Ansys employees.
The aggregate purchase consideration was approximately $34.9 billion, consisting of cash of $17.6 billion, Synopsys Common Stock with a fair value of $17.1 billion, and the balance related to the assumption of certain outstanding Ansys equity awards and the settlement of pre-existing relationships. We acquired Ansys to combine
Synopsys’ semiconductor electronic design automation expertise with Ansys’ S&A capabilities to address the growing demand for integrated design and simulation tools across various industries.
We funded the Cash Consideration in the Ansys Merger through a combination of cash on hand, the net proceeds from the issuance of the Senior Notes, and the borrowings under the Term Loan Agreement, each as defined and discussed in Note 10. Senior Notes, Bridge Commitment Letter, Term Loan and Revolving Credit Facilities of the Notes to Consolidated Financial Statements in this Annual Report.

(1) Represents the total cash paid to settle 88.1 million outstanding shares of Ansys Common Stock as of the Acquisition Date at $199.91 per share and for the settlement of fractional shares.
(2) Represents the fair value of 30.0 million shares of Synopsys Common Stock issued to settle 88.1 million outstanding shares of Ansys Common Stock. Synopsys issued 0.3399 of a share of Synopsys Common Stock for each Ansys share. The fair value of Synopsys Common Stock was $571.20 per share as of the Acquisition Date.
(3) Represents the fair value of assumed Ansys options and RSUs attributed to pre-combination services. See Note 15. Employee Benefit Plans for additional information.
We allocated the purchase price to tangible and identified intangible assets acquired and liabilities assumed based on their preliminary estimated fair values, which were determined using generally accepted valuation techniques based on estimates and assumptions made by management at the time of acquisition. These estimates and assumptions are believed to be reasonable, but they are inherently uncertain and may be subject to material change as additional information becomes available during the respective measurement period, which will not exceed 12 months from applicable acquisition date. The primary areas that are preliminary relate to the fair values of goodwill, intangible assets, certain tangible assets and liabilities, and income taxes.
Goodwill is primarily attributed to the assembled workforce and anticipated synergies and economies of scale expected from the integration of the Ansys business. The synergies include certain cost savings, operating efficiencies and other strategic benefits projected to be achieved as a result of the Ansys Merger. The goodwill was assigned to the Design Automation reporting unit and the amount recognized was not deductible for tax purposes.
The operating results of Ansys have been included in our consolidated financial statements for the fiscal year ended October 31, 2025 from the Acquisition Date.
Intangible Assets
The estimated fair value and weighted average useful life of the Ansys intangible assets were as follows:

Useful Lives
(in thousands)
(in years)
Core/developed technologies(1)
$6,500,000

Trademarks and trade names(4)
950,000 23
Total identified intangible assets
$12,990,000 
(1) Core/developed technology was identified from the products of Ansys and its preliminary fair value was determined using the relief-from-royalty method under the income approach. The relief-from-royalty method applies a royalty rate to projected income to quantify the benefit of owning the intangible asset rather than paying a royalty for use of the asset. The discount rate was determined at the time of measurement based on an analysis of the implied internal rate of return of the transaction, weighted-average cost of capital, and weighted-average return on assets. The economic useful life was determined based on the technology cycle related to each developed technology, as well as the cash-flows over the forecast period.

(2) Customer relationships represent the preliminary fair value of future projected revenue that will be derived from sales of products to existing Ansys customers. The fair value was determined using the multi-period excess earnings method under the income approach, which involves isolating the net earnings attributable to the asset being measured based on present value of the incremental after-tax cash flows (excess earnings) attributable solely to the intangible asset over its remaining useful life. The economic useful life was determined based on historical customer turnover rates and the useful life of developed technology.

(3) Contract rights intangible, which represents contracted but unsatisfied or partially unsatisfied performance obligations, primarily relates to the dollar value of purchase arrangements with customers. The preliminary fair value was determined using the multi-period excess earnings method under the income approach. The economic useful life is based on the time to fulfill the outstanding order backlog obligation.

(4)Trademarks and trade names refers to Ansys brand assets. The preliminary fair value was determined by applying the relief-from-royalty method under the income approach. This method is based on the application of a royalty rate to forecasted revenue attributable to Ansys brand assets. The economic useful life was determined based on the expected usage period of the brand assets and the anticipated cash flows over the forecast period.
We believe the amounts of purchased intangible assets recorded above represent the fair values of and approximate the amounts a market participant would pay for these intangible assets as of the date of the Ansys Merger.
The Optical Solutions Group and PowerArtist RTL Divestitures
Following the determination that it was a necessary step towards obtaining governmental approval of and successfully closing the Ansys Merger, on September 3, 2024, we signed a definitive agreement for the sale of our Optical Solutions Group (OSG) to Keysight Technologies, Inc. (such sale, the Optical Solutions Divestiture). Ansys has similarly entered into a definitive agreement with Keysight Technologies, Inc. for the sale of its PowerArtist RTL business (such sale, together with the Optical Solutions Divestiture, the Regulatory Divestitures).
The Regulatory Divestitures did not represent a strategic shift in operations that would have a major effect on Synopsys' business and are also not material to our financial results, and therefore, are not presented as discontinued operations. The assets and liabilities of OSG and PowerArtist were classified as assets held for sale as of the Acquisition Date. OSG and PowerArtist were included in our Design Automation segment.
On October 17, 2025, we completed the Regulatory Divestitures for cash consideration of $604.0 million. As the result of the Regulatory Divestitures, we disposed $55.1 million of net assets including goodwill of $19.5 million, and recognized a pre-tax gain on sale of $548.9 million, which was included in other income (expense), net in the
consolidated statements of income. In addition, we incurred $32.6 million divestiture-related expenses, resulting in a net pre-tax gain on sale of $516.3 million.

The unaudited pro forma financial information reflects significant non-recurring adjustments, including transaction costs of $298.4 million, stock-based compensation costs of $71.5 million, and severance costs of $8.2 million. This information is provided for informational purposes only and is not necessarily indicative of our consolidated results of operations of the combined business had the acquisition actually occurred at the beginning of fiscal year 2024, or of the results of our future operations of the combined business.
Fiscal 2024
During fiscal 2024, we completed several acquisitions for an aggregate purchase consideration of $159.3 million, net of cash acquired. We do not consider these acquisitions to be material, individually or in the aggregate, to our consolidated financial statements. The total purchase consideration was allocated as follows: $78.9 million to identifiable intangible assets, $96.1 million to goodwill, and $15.7 million to net tangible liabilities. The goodwill recognized from these acquisitions, of which $61.8 million was attributable to the Design Automation reporting unit, and $34.3 million was attributable to the Design IP reporting unit, was not deductible for income tax purposes.
Fiscal 2023
During fiscal 2023, we completed several acquisitions for an aggregate purchase consideration of $295.4 million, net of cash acquired. We do not consider these acquisitions to be material, individually or in the aggregate, to our consolidated financial statements. The total purchase consideration was allocated as follows: $95.8 million to identifiable intangible assets, $229.4 million to goodwill, and $29.8 million to net tangible liabilities. The goodwill recognized from these acquisitions was assigned to the Design Automation reporting unit, of which $5.7 million was deductible for income tax purposes.
Redeemable Non-controlling Interest
During the second quarter of fiscal 2022, we acquired a 75% equity interest in OpenLight Photonics, Inc. (OpenLight) for cash consideration of $90.0 million. The remaining 25% equity interest in OpenLight was held by Juniper Networks, Inc. (the Minority Investor) from their contribution of IP and certain tangible assets.
The agreement with the Minority Investor contained redemption features whereby the interest held by the Minority Investor was redeemable either (1) at the option of the Minority Investor on or after the third anniversary of the acquisition or sooner in certain circumstances or (2) at our option beginning on the third anniversary of the acquisition. This option was exercisable at the greater of fair value at the time of redemption or $30.0 million. The fair value of the option was initially valued at $10.1 million, resulting in a total consideration of $100.1 million.
As of the end of fiscal 2024, upon issuance of new OpenLight stock, our ownership interest in OpenLight was reduced to 71% and the Minority Investor was reduced to 24%. On December 23, 2024, we exercised the call option to purchase the remaining ownership interest held by the Minority Investor at a redemption price of $30.0 million, bringing our ownership interest in OpenLight to 95%.
Subsequently on December 30, 2024, we divested our entire ownership interest in OpenLight. We had previously recorded an impairment charge of $53.5 million related to acquired intangible assets in OpenLight in fiscal 2024. See Note 6. Goodwill and Intangible Assets of the Notes to Consolidated Financial Statements in this Annual Report for more information. The goodwill related to the OpenLight acquisition was assigned to our Design Automation
reporting unit. The resulting loss on the OpenLight divestiture, included in other income (expense), net in the consolidated statements of income, was not material to our results of operation.
During fiscal 2025, 2024 and 2023, OpenLight incurred a net loss of $3.5 million, $91.7 million and $40.9 million, respectively, of which $0.8 million, $22.0 million and $10.0 million, respectively, was attributable to redeemable non-controlling interest. The carrying value of the redeemable non-controlling interest was recorded at its estimated fair value of $30.0 million as of October 31, 2024 in the consolidated balance sheets. We have excluded the financial results of OpenLight from our consolidated financial statements from the date of sale.
Transaction Costs
Transaction costs for acquisitions, primarily related to the Ansys Merger, were $267.1 million, $161.8 million and $13.8 million during fiscal 2025, 2024 and 2023, respectively. These costs mainly consisted of professional fees and administrative costs for closed and pending acquisitions, as well as the Bridge Commitment financing costs, and were expensed as incurred in our consolidated statements of income.

Contract Balances
The timing of revenue recognition may differ from the timing of invoicing customers, resulting in receivables, contract assets, or contract liabilities (deferred revenue) in our consolidated balance sheets. For specific software, hardware, and IP agreements with payment plans, we record an unbilled receivable associated with revenue recognized upon transfer of control, as it holds an unconditional right to invoice and receive payment in the future for those transferred products or services.
A contract asset is recorded when revenue is recognized before we have the unconditional right to invoice or retains performance risk concerning that performance obligation. These contract assets transition to receivables when the rights become unconditional, generally upon the completion of a milestone. The contract assets listed below are included in prepaid and other current assets and other long-term assets in our consolidated balance sheets.
Contract balances are as follows:
As of October 31,
20252024
 (in thousands)
Contract assets, net$1,222,029 $757,075 
Unbilled receivables$45,528 $44,166 
Deferred revenue$2,628,518 $1,732,568 
Long-term contract assets were $336.4 million as of October 31, 2025.
During fiscal 2025, we recognized revenue of $1.5 billion that was included in the deferred revenue balance as of October 31, 2024, including previously unfulfilled contracts that have expired and are no longer subject to an implied promise to provide future services. During fiscal 2024, we recognized revenue of $1.5 billion, that was included in the deferred revenue balance as of October 31, 2023, including previously unfulfilled contracts that have expired and are no longer subject to an implied promise to provide future services.
Contracted but unsatisfied or partially unsatisfied performance obligations (backlog) were approximately $11.4 billion as of October 31, 2025, which includes $2.0 billion in non-cancellable Flexible Spending Account (FSA) commitments from customers where actual product selection and quantities of specific products or services are to be determined by customers at a later date. We have elected to exclude future sales-based royalty payments from the remaining performance obligations. Approximately 45% of the backlog as of October 31, 2025, excluding non-cancellable FSA, is expected to be recognized as revenue over the next 12 months, with the remainder to be recognized thereafter. The majority of the remaining backlog is expected to be recognized in the following three years. The backlog was approximately $8.1 billion as of October 31, 2024, which included $1.2 billion in non-cancellable FSA commitments from customers.
During fiscal 2025 and 2024, we recognized $125.3 million and $104.4 million, respectively, from performance obligations satisfied from sales-based royalties earned during the periods.
Costs of Obtaining a Contract with Customer
The incremental costs of obtaining a contract with a customer, which consist primarily of direct sales commission earned upon execution of the contract, were capitalized in compliance with authoritative guidance, and amortized over the estimated period of which the benefit is expected to be received. As direct sales commission paid for renewals are commensurate with the amounts paid for initial contracts, the deferred incremental costs will be recognized over the contract term.
Capitalized commission costs, net of accumulated amortization, as of October 31, 2025 were $92.5 million, of which $13.4 million were included in prepaid and other current assets, and $79.1 million in other long-term assets in our consolidated balance sheets. Capitalized commission costs, net of accumulated amortization, as of October 31, 2024 were $72.8 million, included in other long-term assets in our consolidated balance sheets. Amortization of these assets were $53.2 million, $48.5 million and $52.1 million during fiscal 2025, 2024 and 2023, respectively, and are included in sales and marketing expense in our consolidated statements of income.

Goodwill and Intangible Assets Goodwill and Intangible Assets
Goodwill
Goodwill represents the excess of the aggregate purchase price over the fair value of the net tangible and identifiable intangible assets acquired in business combination. The change in the goodwill during fiscal 2025 resulted primarily from $23.4 billion related to the Ansys Merger. For additional information, refer to Note 4. Business Combination of the Notes to Consolidated Financial Statements in this Annual Report.
We performed the required annual goodwill assessment in the fourth quarter of fiscal 2025, and concluded the goodwill was not impaired. There was no goodwill impairment in fiscal 2025, 2024 and 2023.

Intangible Assets
Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be fully recoverable. The change in the gross carrying amounts of intangible assets in fiscal 2025 was due to the Ansys Merger. For additional information, refer to Note 4. Business Combination of the Notes to Consolidated Financial Statements in this Annual Report.
During the fourth quarter of fiscal 2024, we assessed long-lived assets for impairment and recorded an impairment charge of $53.5 million related to acquired intangible assets. The impairment charge was triggered by a decline in estimated fair value resulting from the reductions in the expected future cash flows associated with our core/developed technology intangible assets related to our OpenLight business. There were no other impairment charges for long-lived assets in fiscal 2025, 2024 and 2023.

Our short-term investment portfolio includes both corporate and government debt securities that have a maximum maturity of three years. The longer the duration of these securities, the more susceptible they are to changes in market interest rates and bond yields. As yields increase, those securities with a lower yield-at-cost show a mark-to-market unrealized loss. Most of our unrealized losses are due to changes in market interest rates, and bond yields.

As of October 31, 2025, our investments that were in a continuous loss position of 12 months or more, as well as the unrealized losses on those investments, were immaterial.

Restricted cash
We include amounts generally described as restricted cash in cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts shown in the consolidated statements of cash flows. Restricted cash is primarily associated with deposits for office leases and employee loan programs.

Non-marketable equity securities
Our portfolio of non-marketable equity securities consists of strategic investments in privately held companies. During the first quarter of fiscal 2024, we completed the sale of certain strategic investments in privately-held companies. The gain recognized from the sales was $55.1 million and included in other income (expense), net, in our consolidated statements of income. There were no material impairments of non-marketable equity securities in fiscal 2025, 2024, and 2023.
Derivatives
We recognize derivative instruments as either assets or liabilities in the consolidated balance sheets at fair value and provide qualitative and quantitative disclosures about such derivatives. We operate internationally and are exposed to potentially adverse movements in foreign currency exchange and interest rates. We enter into hedges in the form of foreign currency forward contracts to reduce our exposure to foreign currency rate changes on non-functional currency denominated forecasted transactions and balance sheet positions including: (1) certain assets and liabilities, (2) shipments forecasted to occur within approximately one month, (3) future billings and revenue on previously shipped orders, and (4) certain future intercompany invoices denominated in foreign currencies.
The majority of the forward contracts are short-term with maturity of up to 30 months at inception. We do not use foreign currency forward contracts for speculative or trading purposes. We enter into foreign exchange forward contracts with high credit quality financial institutions that are rated "A" or above and to date have not experienced nonperformance by counterparties. In addition, we mitigate credit risk in derivative transactions by permitting net settlement of transactions with the same counterparty and anticipate continued performance by all counterparties to such agreements.
The assets or liabilities associated with the forward contracts are recorded at fair value in other current assets or accrued liabilities in the consolidated balance sheets. The accounting for gains and losses resulting from changes in fair value depends on the use of the foreign currency forward contract and whether it is designated and qualifies for hedge accounting. The cash flow impact upon settlement of the derivative contracts is included in net cash provided by operating activities in the consolidated statements of cash flows.
Additionally, in order to manage interest rate exposure related to anticipated debt transactions, in the first quarter of fiscal 2025, we entered into treasury rate lock agreements to hedge against unfavorable interest rate changes. The accounting for gains and losses resulting from changes in fair value depends on whether these are designated and qualify for hedge accounting. The assets or liabilities associated with these derivatives are recorded at fair value in other current assets or accrued liabilities in the consolidated balance sheets. The cash flow impact upon settlement of these derivative contracts is included in net cash used in operating activities in the consolidated statements of cash flows.
Cash Flow Hedging Activities
Certain foreign exchange forward contracts are designated and qualify as cash flow hedges. These contracts have durations of up to 30 months or less. Certain forward contracts are rolled over periodically to capture the full length of exposure to our foreign currency risk, which can be up to three years. To receive hedge accounting treatment, all hedging relationships are formally documented at the inception of the hedge, and the hedges must be highly effective in offsetting changes to future cash flows on the hedged transactions. The related gains or losses resulting from changes in fair value of these hedges is initially reported, net of tax, as a component of other comprehensive income (loss) (OCI) in stockholders’ equity and reclassified into revenue or operating expenses, as appropriate, at the time the hedged transactions affect earnings. We expect a majority of the hedge balance in OCI to be reclassified to the statements of income within the next 12 months.
We did not record any gains or losses related to discontinuation of foreign exchange forward contracts cash flow hedges for fiscal years 2025, 2024 and 2023.
During the first quarter of fiscal 2025, we entered into 6-month interest rate hedge contracts (the 2025 Rate Lock Agreements) with notional value of $2.0 billion to lock the benchmark interest rate prior to expected debt issuances with 10-year and 30-year terms. The objective of the 2025 Rate Lock Agreements was to hedge the risk associated with the variability in interest rates due to the changes in the benchmark rate leading up to the closing of the intended financing on the notional amount being hedged. To receive hedge accounting treatment, the hedging relationships are formally documented at the inception of the hedge, and the hedges must be highly effective in offsetting changes to future cash flows on the hedged transactions. These derivatives are designated as cash flow hedges with unrealized gains and losses deferred in OCI. The 2025 Rate Lock Agreements terminated and settled in the second quarter of fiscal 2025, and we recorded the fair value of $121.6 million as a loss within OCI. The unrealized loss of $121.6 million is being amortized to interest expense over the life of the related debt. We expect $7.0 million of the unrealized loss to be amortized to interest expense over the next 12 months. As of October 31, 2025, the unamortized portion of the fair value of the 2025 Rate Lock Agreements was $117.0 million. We had no interest rate hedge contracts outstanding as of October 31, 2025.
During the second quarter of fiscal 2025, we entered into a deferred payment agreement with the counterparty bank to defer the cash settlement of 2025 Rate Lock Agreements over a period of 5.5 years with installments due semi-annually. The implied interest rate is 3.45%. This liability is recognized in our consolidated balance sheets as short-term debt for the portion due within the next 12 months and as long-term debt for the remaining portion. There were no debt covenants applicable to the deferred payment agreement.
Non-designated Hedging Activities
Our foreign exchange forward contracts that are used to hedge non-functional currency denominated balance sheet assets and liabilities are not designated as hedging instruments. Accordingly, any gains or losses from changes in the fair value of the forward contracts are recorded in other income (expense), net. The gains and losses on these forward contracts generally offset the gains and losses associated with the underlying assets and liabilities, which are also recorded in other income (expense), net. The duration of the forward contracts for hedging our balance sheet exposure is approximately one month.
We also have certain foreign exchange forward contracts for hedging certain international revenues and expenses that are not designated as hedging instruments. Accordingly, any gains or losses from changes in the fair value of these forward contracts are recorded in other income (expense), net. The gains and losses on these forward contracts generally offset the gains and losses associated with the foreign currency in operating income. The duration of these forward contracts is usually less than one year. The overall goal of our hedging program is to minimize the impact of currency fluctuations on the net income over the fiscal year.
The effects of the non-designated foreign currency derivative instruments in the consolidated statements of income are summarized as follows:

Our exposure to the market gains or losses will vary over time as a function of currency exchange rates. The amounts ultimately realized upon settlement of these financial instruments, together with the gains and losses on the underlying exposures, will depend on actual market conditions during the remaining life of the instruments.

Fair Value Disclosures [Abstract]  
Fair Value Measurements Fair Value Measurements
ASC 820-10, Fair Value Measurements and Disclosures, defines fair value, establishes guidelines and enhances disclosure requirements for fair value measurements. The accounting guidance requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The accounting guidance also establishes a fair value hierarchy based on the independence of the source and objective evidence of the inputs used. There are three fair value hierarchies based upon the level of inputs that are significant to fair value measurement:
Level 1—Observable inputs that reflect quoted prices (unadjusted) for identical instruments in active markets;
Level 2—Observable inputs other than quoted prices for identical instruments in active markets, quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in inactive markets, and model-driven valuations in which all significant inputs and significant value drivers are observable in active markets; and
Level 3—Unobservable inputs derived from fair valuation techniques in which one or more significant inputs or significant value drivers are unobservable.
On a recurring basis, we measure the fair value of certain assets and liabilities, which include cash equivalents, short-term investments, marketable securities, non-qualified deferred compensation plan assets, contingent consideration receivable, and foreign currency derivative contracts.
Our cash equivalents, short-term investments and marketable securities are classified within Level 1 or Level 2 because they are valued using quoted market prices in an active market or alternative independent pricing sources and models utilizing market observable inputs.
Our non-qualified deferred compensation plan assets consist of money market and mutual funds invested in domestic and international marketable securities that are directly observable in active markets and are therefore classified within Level 1.
Our foreign currency derivative contracts are classified within Level 2 because these contracts are not actively traded and the valuation inputs are based on quoted prices and market observable data of similar instruments.
Our borrowings under our Credit and Term Loan facilities are classified within Level 2 because these borrowings are not actively traded and have a variable interest rate structure based upon market rates currently available to us for debt with similar terms and maturities. See Note 10. Senior Notes, Bridge Commitment Letter, Term Loan and Revolving Credit Facilities of the Notes to Consolidated Financial Statements in this Annual Report for more information on these borrowings.
Our contingent consideration receivable, which was recorded in connection with the Software Integrity Divestiture, was classified within Level 3 because it was estimated using significant inputs that were not observable in the market. See Note 3. Discontinued Operations of the Notes to Consolidated Financial Statements in this Annual Report for additional information.

Senior Notes
On March 17, 2025, we issued $10.0 billion in aggregate principal amount of senior, unsecured and unsubordinated long-term notes, including $1.0 billion aggregate principal amount of 4.550% Senior Notes due April 1, 2027 (the 2027 Senior Notes), $1.0 billion aggregate principal amount of 4.650% Senior Notes due April 1, 2028 (the 2028 Senior Notes), $2.0 billion aggregate principal amount of 4.850% Senior Notes due April 1, 2030 (the 2030 Senior Notes), $1.5 billion aggregate principal amount of 5.000% Senior Notes due April 1, 2032 (the 2032 Senior Notes), $2.4 billion aggregate principal amount of 5.150% Senior Notes due April 1, 2035 (the 2035 Senior Notes) and $2.1 billion aggregate principal amount of 5.700% Senior Notes due April 1, 2055 (the 2055 Senior Notes and together with the 2027 Senior Notes, 2028 Senior Notes, 2030 Senior Notes, 2032 Senior Notes and 2035 Senior Notes, the Senior Notes). Our total proceeds were approximately $9.9 billion, net of original issuance discount of $17.0 million and total issuance costs of $70.2 million. Interest on the Senior Notes is payable semi-annually on April 1 and October 1 of each year, beginning on October 1, 2025. The discount and issuance costs on our Senior Notes are amortized to interest expense over the terms of the respective notes using the effective interest method. The effective rates for the Senior Notes include the interest on the notes, the accretion of the discount and the amortization of issuance costs.
The Senior Notes were issued under an indenture, dated as of March 17, 2025 (the Base Indenture), as supplemented by the first supplemental indenture, dated as of March 17, 2025 (the Supplemental Indenture and, together with the Base Indenture, the Indenture), each between Synopsys and U.S. Bank Trust Company, National Association, as trustee.
The net proceeds of the Senior Notes were used to fund a portion of the Cash Consideration in the Ansys Merger and pay related transaction fees and expenses.
At any time and from time to time prior to their respective par call dates (as defined in the Indenture and applicable series of Senior Notes or, in the case of the 2027 Senior Notes, prior to the maturity date), Synopsys may redeem the applicable series of the Senior Notes at its option, in whole or in part, at any time and from time to time, at the “make-whole” redemption price (calculated as set forth in the Indenture and applicable series of Senior Notes), plus, in each case, accrued and unpaid interest, if any, on the Senior Notes being redeemed to, but excluding, the redemption date. In addition, on or after the applicable par call date, Synopsys may redeem the 2028 Senior Notes, 2030 Senior Notes, 2032 Senior Notes, 2035 Senior Notes or 2055 Senior Notes at its option, in whole or in part, at
any time and from time to time, at a redemption price equal to 100% of the principal amount of the Senior Notes being redeemed plus accrued and unpaid interest, if any, thereon to, but excluding, the applicable redemption date.
The Indenture contains covenants limiting Synopsys’ ability to create certain liens and enter into certain sale and leaseback transactions. These covenants are subject to important limitations and exceptions as set forth in the Indenture.
Based on the trading prices of the Senior Notes, the fair value of our Senior Notes was $10.1 billion as of October 31, 2025. While the Senior Notes are recorded at cost, the fair value of long-term debt was determined based on observable market prices in less active markets and categorized as Level 2 for purposes of the fair value measurement hierarchy.
As of October 31, 2025 , we were in compliance with all of our covenants under the Indenture.
During the first quarter of fiscal 2025, we entered into 6-month interest rate hedge contracts with an aggregate notional amount of $2.0 billion to manage the variability in cash flows due to changes in benchmark interest rates related to the Senior Notes. These interest rate hedge contracts were terminated and settled during the second quarter of fiscal 2025, and we entered into a deferred payment agreement with the counterparty bank to defer the cash settlement. See Note 8. Financial Assets and Liabilities of the Notes to Consolidated Financial Statements for more information on these cash flow hedging activities.
Bridge Commitment
On January 15, 2024, we entered into the Bridge Commitment Letter with certain financial institutions that committed to provide, subject to the satisfaction of customary closing conditions, the bridge commitment (the Bridge Commitment) for the purpose of financing a portion of the aggregate Cash Consideration in the Ansys Merger and paying related fees and expenses in connection with the Ansys Merger and the other transactions contemplated by the Merger Agreement.
On October 3, 2024, we reduced the Bridge Commitment by $1.1 billion to $10.6 billion following the closing of the Software Integrity Divestiture. On March 17, 2025, we further reduced the Bridge Commitment by $9.9 billion following the issuance of the Senior Notes. On the Acquisition Date, we terminated the approximately $690.0 million in remaining Bridge Commitment, reducing the Bridge Commitment to $0.
Term Loan
On February 13, 2024, we entered into a term loan facility credit agreement (the Term Loan Agreement) in connection with the financing of the Ansys Merger. On July 17, 2025, we borrowed the full $4.3 billion available under the Term Loan Agreement to fund a portion of the Cash Consideration in the Ansys Merger and to pay transaction fees, premiums and expenses related to the Ansys Merger.
The Term Loan Agreement provides for two tranches of senior unsecured term loans: a $1.45 billion tranche (Tranche 1) that matures on July 17, 2027 and a $2.85 billion tranche (Tranche 2) that matures on July 17, 2028. On October 17, 2025, we made an early repayment of $850.0 million on the Tranche 1 Term Loan. The outstanding balance under the Term Loan Agreement as of October 31, 2025 was $3.45 billion.
Under the Term Loan Agreement, borrowings will bear interest on the principal amount outstanding at a floating rate based on, at Synopsys’ election, (i) the Adjusted Term SOFR Rate (as defined in the Term Loan Agreement) plus an applicable margin based on the credit ratings of Synopsys ranging from 0.875% to 1.375% (in the case of Tranche 1) or 1.000% to 1.500% (in the case of Tranche 2) or (ii) the ABR (as defined in the Term Loan Agreement) plus an applicable margin based on the credit ratings of Synopsys ranging from 0.000% to 0.375% (in the case of Tranche 1) or 0.000% to 0.500% (in the case of Tranche 2).
The Term Loan Agreement contains a financial covenant requiring that Synopsys maintain a maximum consolidated leverage ratio, as well as certain other non-financial covenants. As of October 31, 2025, we were in compliance with the financial covenant as well as the other covenants.
Subsequent Event
On November 17, 2025, we made an early repayment of $600.0 million on the Tranche 1 Term Loan, which reduced the Tranche 1 outstanding balance to $0, and an early repayment of $300.0 million on the Tranche 2 Term Loan. On December 17, 2025 we made another early repayment of $2.2 billion on the Tranche 2 Term Loan, which reduced the Tranche 2 outstanding balance to $350.0 million.
Revolving Credit Facilities
On February 13, 2024, we entered into a Sixth Amendment Agreement (the Sixth Amendment), which amended and restated our previous revolving credit agreement, dated as of December 14, 2022 (as amended and restated, the Revolving Credit Agreement).
The Revolving Credit Agreement provides an unsecured $850.0 million committed multicurrency revolving credit facility and an unsecured uncommitted incremental revolving loan facility of up to $150.0 million. The maturity date of the revolving credit facility is December 14, 2027, which may be extended at our option.
Under the Sixth Amendment, certain amendments became effective on February 13, 2024 and certain additional amendments became effective on the Acquisition Date. The Sixth Amendment amended the financial covenant to allow netting of the cash proceeds of certain debt incurred to finance the Ansys Merger as well as certain other modifications set forth therein. The Sixth Amendment, among other things, also amended: (i) the applicable margin used to determine the interest that accrues on loans and the facility fee payable under the revolving credit facility to be based on our credit ratings, (ii) the financial covenant thresholds under the financial covenant in the Revolving Credit Agreement requiring us to maintain a maximum consolidated leverage ratio and (iii) certain conditions to borrowing, other non-financial covenants and events of default.
The Revolving Credit Agreement contains a financial covenant requiring us to maintain a maximum consolidated leverage ratio, as well as other non-financial covenants. As of October 31, 2025, we were in compliance with the financial covenant.
Interest under the Revolving Credit Agreement accrues on dollar-denominated loans at a floating rate based on, at Synopsys’ election, (i) the Adjusted Term SOFR Rate (as defined in the Revolving Credit Agreement) plus an applicable margin based on our credit ratings ranging from 0.795% to 1.200% or (ii) the ABR (as defined in the Revolving Credit Agreement) plus an applicable margin based on our credit ratings ranging from 0.000% to 0.200%. In addition to the interest on any outstanding loans, Synopsys is also required to pay a facility fee on the entire portion of the revolving credit facility ranging from 0.080% to 0.175% based on the credit ratings of Synopsys on the daily amount of the revolving commitment.
There was no outstanding balance under the Revolving Credit Agreement as of October 31, 2025 and October 31, 2024.
Other Borrowings
In July 2018, we entered into a 12-year 220.0 million Renminbi (approximately $33.0 million) credit agreement with a lender in China to support our facilities expansion. Borrowings bear interest at a floating rate based on the 5-year Loan Prime Rate plus 0.74%. As of October 31, 2025, we had $13.1 million outstanding balance under the agreement.
The carrying amount of the short-term and long-term debt approximates the estimated fair value.

Legal Proceedings
We are subject to routine legal proceedings, as well as demands, claims and threatened litigation that arise in the normal course of our business. The ultimate outcome of any litigation is often uncertain and unfavorable outcomes could have a negative impact on our results of operations and financial condition. We regularly review the status of each significant matter and assess its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount is estimable, we accrue a liability for the estimated loss. Legal proceedings are inherently uncertain and as circumstances change, it is possible that the amount of any accrued liability may increase, decrease, or be eliminated.
We have determined that no disclosure of estimated loss is required for a claim against us because: (1) there is not a reasonable possibility that a loss exceeding amounts already recognized (if any) may be incurred with respect to such claim; (2) a reasonably possible loss or range of loss cannot be estimated; or (3) such estimate is immaterial.
Tax Matters
We undergo examination from time to time by U.S. and foreign authorities for non-income based taxes, such as sales, use and value-added taxes, and are currently under examination by tax authorities in certain jurisdictions. If the potential loss from such examinations is considered probable and the amount or the range of loss could be estimated, we would accrue a liability for the estimated expense. In addition to the foregoing, we are, from time to time, party to various other claims and legal proceedings in the ordinary course of our business, including with tax and other governmental authorities. For a description of certain of these other matters, refer to Note 17. Income Taxes of the Notes to Consolidated Financial Statements in this Annual Report.

Employee Benefit Plans

Share-Based Payment Arrangement [Abstract]  
Employee Benefit Plans Employee Benefit Plans
Employee Stock Purchase Plan
Under our Employee Stock Purchase Plan (ESPP), participating employees are granted the right to purchase shares of common stock at a price per share that is 85% of the lesser of the fair market value of the shares at (1) the beginning of an offering period (generally, a rolling two year period) or (2) the purchase date (generally occurring at the end of each semi-annual purchase period), subject to the terms of ESPP, including a limit on the number of shares that may be purchased in a purchase period.
On April 10, 2025, our stockholders approved amendments to the ESPP to increase the number of shares of common stock authorized for issuance under the plan by 2.2 million shares. During fiscal 2025, 2024 and 2023, we issued 0.5 million, 0.5 million, and 0.6 million shares, respectively, under the ESPP at average per share prices of $375.72, $315.24 and $266.82, respectively. As of October 31, 2025, 14.7 million shares of common stock were reserved for future issuance under the ESPP.
Equity Incentive Plans
2006 Employee Equity Incentive Plan. On April 25, 2006, our stockholders approved the 2006 Employee Equity Incentive Plan (2006 Employee Plan), which provides for the grant of incentive stock options, non-statutory stock options, restricted stock awards, RSU awards, stock appreciation rights and other forms of equity compensation, including performance stock awards and performance cash awards, as determined by the plan administrator. The terms and conditions of each type of award are set forth in the 2006 Employee Plan and in the award agreements governing particular awards.
RSUs are granted under the 2006 Employee Plan as part of our incentive compensation program. In general, RSUs vest over three to four years and are subject to the employee's continuing service with us. RSUs granted with specific performance criteria and certain market conditions vest to the extent the performance and market conditions are met. For each RSU granted under the 2006 Employee Plan, a share reserve ratio of 1.70 is applied for the purpose of determining the remaining number of shares reserved for future grants under the plan. Options granted under this plan generally have a contractual term of seven years and generally vest over four years.
On April 10, 2025, our stockholders amended the 2006 Employee Plan to, among other things, increase the number of shares of common stock reserved for future issuance under the plan by 1.6 million shares. As of October 31, 2025, an aggregate of 1.1 million stock options and 3.4 million RSUs were outstanding, and 14.1 million shares were available for future issuance under the 2006 Employee Plan.
2017 Non-Employee Directors Equity Incentive Plans. On April 6, 2017, our stockholders approved the 2017 Non-Employee Directors Equity Incentive Plan (2017 Directors Plan). The 2017 Directors Plan provides for equity awards to non-employee directors in the form of stock options, RSUs, restricted stock or a combination thereof. On April 6, 2017, our stockholders approved an aggregate of 0.45 million shares of common stock reserved under the 2017 Directors Plan.
We grant restricted stock awards and options under the 2017 Directors Plan. Restricted stock awards generally vest on an annual basis and options vest over a period of three years. As of October 31, 2025, 9,395 stock options were outstanding, and a total of 359,486 shares of common stock were reserved for future issuance under the 2017 Directors Plan.
Assumed Equity Plans
As of the Acquisition Date, we assumed outstanding equity incentive awards under the following Ansys equity incentive plans: (i) the Fourth Amended and Restated Ansys, Inc. 1996 Stock Option and Grant Plan, (ii) the Fifth Amended and Restated Ansys, Inc. 1996 Stock Option and Grant Plan, and (iii) the Ansys, Inc. 2021 Equity and Incentive Compensation Plan (each, an Assumed Equity Plan, and collectively the Assumed Equity Plans). The awards under the Assumed Equity Plans, previously issued in the form of stock options and RSUs, were generally settled as follows:
(1)    Each award of Ansys RSUs held by non-employee directors and specified employees that were outstanding immediately prior to the Acquisition Date (the specified RSUs), including any RSUs deferred as part of Ansys'
director deferred compensation program, was canceled and terminated and converted into the right to receive the Merger Consideration as of the Acquisition Date.
(2)    Each award of Ansys stock options and RSUs (other than specified RSUs) that was outstanding and unvested immediately prior to the Acquisition Date was assumed by us (each, an Assumed Option and Assumed RSU, and collectively, the Assumed Equity Awards) and converted to stock options exercisable and RSUs settleable in the number of shares of our common stock equal to the product of (i) the number of Ansys shares underlying such Assumed Equity Awards as of immediately prior to the Acquisition Date multiplied by (ii) the conversion ratio defined in the Merger Agreement. Any Ansys performance-based RSUs that were assumed by us will only be subject to time-based vesting. The number of Ansys shares underlying the performance-based RSUs for which the performance period was not complete as of the Acquisition Date was based on the target level of performance, and the number of Ansys shares underlying the performance-based RSUs for which the performance period was complete as of the Acquisition Date was based on the actual level of performance. The Assumed Equity Awards generally retain all of the rights, terms and conditions of the respective plans under which they were originally granted, including the same service-based vesting schedule, applicable thereto.
If these assumed equity awards are cancelled, forfeited or expire unexercised, the underlying shares do not become available for future issuance.
As of the Acquisition Date, the estimated fair value of the Assumed Equity Awards was $639.7 million, of which $131.0 million was recognized as goodwill and the balance of $508.7 million is being recognized as stock-based compensation expense over the remainder term of the Assumed Equity Awards. The fair value of the Assumed Equity Awards for services rendered through the Acquisition Date was recognized as a component of the purchase consideration, with the remaining fair value related to the post-combination services to be recorded as stock-based compensation over the remaining vesting period.
A total of 1.1 million shares of our common stock underlying the Assumed Equity Awards that is being recognized as stock-based compensation expense had an estimated weighted average fair value at the Acquisition Date of $453.83 per share. As of October 31, 2025, there were 0.9 million shares of our common stock underlying the outstanding Assumed Equity Awards under the Assumed Equity Plans.
Other Assumed Stock Plans through Acquisitions. In addition, we have assumed certain outstanding stock awards of other acquired companies, including restricted stock units and options. If these assumed equity awards are canceled, forfeited or expire unexercised, the underlying shares do not become available for future grant. As of October 31, 2025, 235 shares of our common stock remained subject to such outstanding assumed equity awards.

Valuation and Expense of Stock-Based Compensation. We estimate the fair value of stock options and employee stock purchase rights under the ESPP on the grant date. The value of awards expected to vest is recognized as expense over the applicable service periods. We use the Black-Scholes option-pricing model to determine the fair value of stock options and employee stock purchase plan rights. The Black-Scholes option-pricing model incorporates various assumptions including expected volatility, expected term and interest rates. The expected volatility for both stock options and employee stock purchase rights is estimated by a combination of implied volatility for publicly traded options of our common stock with a term of six months or longer and the historical stock price volatility over the estimated expected term of such awards, which is based on historical experience.
Restricted stock units are valued based on the closing price of our common stock on the grant date. We use the straight-line attribution method to recognize stock-based compensation costs over the service period of the award except for performance-based RSUs and market-based RSUs.
We estimated the fair value of market-based RSUs on the grant date using a Monte Carlo simulation model. Under the award agreements, the vesting of the market-based RSUs is contingent on achieving total stockholder return (TSR) relative to a peer index as well as revenue growth metrics. The maximum potential awards that may be earned are 187.5% of the target number of the initial awards. For market-based RSUs granted in February and August 2023, the performance period during which the achievement goals will be measured is fiscal 2023, fiscal 2024 and fiscal 2025. The awards will vest in December 2025 if the TSR target, revenue growth metrics, and service conditions are achieved. For market-based RSUs granted in December 2023, the performance period during which the achievement goals will be measured is fiscal 2024, fiscal 2025 and fiscal 2026. The awards will vest in December 2026 if the TSR target, revenue growth metrics, and service conditions are achieved. For market-based RSUs granted in January and February 2025, the performance period during which the achievement goals will be measured is fiscal 2025, fiscal 2026 and fiscal 2027. The awards will vest in December 2027 if the TSR target, revenue growth metrics, and service conditions are achieved.
We estimate the probability of achievement of applicable performance goals for performance-based and market-based RSUs in each reporting period and recognize related stock-based compensation expense using the graded-vesting method. The amount of stock-based compensation expense recognized in any period can vary based on the attainment or expected attainment of the various performance goals. If such performance goals are not ultimately met, no compensation expense is recognized and any previously recognized compensation expense is reversed.

Amounts may be withdrawn from the Deferred Plan pursuant to elections made by the employees in accordance with the terms of the plan. Since the inception of the Deferred Plan, we have not made any matching or discretionary contributions to the Deferred Plan. There are no Deferred Plan provisions that provide for any guarantees or minimum return on investments. Undistributed amounts under the Deferred Plan are subject to the claims of our creditors.
Deferred plan assets and liabilities are as follows:
As of October 31,

Plan liabilities recorded in other long-term liabilities(1)

(1)Undistributed deferred compensation balances due to participants.
Income or loss from the change in fair value of the Deferred Plan assets is recorded in other income (expense), net. The increase or decrease in the fair value of the undistributed Deferred Plan obligation is recorded in total cost of revenue and operating expense. The following table summarizes the impact of the Deferred Plan:

Other Retirement Plans. We sponsor various defined contribution retirement plans for our eligible U.S. and non-U.S. employees. Total contributions to these plans were $80.7 million, $51.3 million, and $50.8 million in fiscal 2025, 2024, and 2023, respectively. For employees in the United States and Canada, we match pre-tax employee contributions up to a maximum of U.S. $7,500 and Canadian $4,000, respectively, per participant per year, except for legacy Ansys employees with maximum matching contributions of 4.25% of the employee's eligible compensation.
Certain of our international subsidiaries sponsor defined benefit retirement plans. The unfunded projected benefit obligation for these defined benefit retirement plans as of October 31, 2025 and 2024 was immaterial and recorded in other long-term liabilities in our consolidated balance sheets.

On December 22, 2017, the Tax Cuts and Jobs Act (Tax Act) was enacted, which significantly changed prior U.S. tax law and includes numerous provisions that affect our business. Effective in our fiscal 2023 year, the Tax Act requires that research and development expenditures be capitalized and amortized instead of being deducted when incurred. Domestic research is capitalized over five years and foreign research is capitalized over fifteen years. Capitalization of research and development expenditures also results in a corresponding deferred tax benefit and decreased our effective tax rate due to increasing the foreign-derived intangible income deduction.
We have provided for foreign withholding taxes on undistributed earnings of certain of our foreign subsidiaries to the extent such earnings are no longer considered to be indefinitely reinvested in the operations of those subsidiaries. Where foreign subsidiaries are considered indefinitely reinvested, and if the tax effect of undistributed earnings and other outside basis differences were recognized, the nature of taxes expected would primarily be withholding, taxes in non-conforming states, and taxes on intermediate holding companies outside of the U.S., net of foreign tax credits where available. As of October 31, 2025, the taxes due, after allowable foreign tax credits, are not expected to be material.

It is more likely than not that the results of future operations will be able to generate sufficient taxable income to realize the net deferred tax assets. The valuation allowance provided against our deferred tax assets as of October 31, 2025 is mainly attributable to foreign tax credits available to non-U.S. subsidiaries. The valuation allowance decreased by a net of $131.8 million in fiscal 2025, primarily related to realization of California research credits.
We have the following tax loss and credit carryforwards available to offset future income tax liabilities:
CarryforwardAmountExpiration

The federal and state net operating loss carryforward is from acquired companies and the annual use of such loss is subject to significant limitations under Internal Revenue Code Section 382. Foreign tax credits may only be used to offset tax attributable to foreign source income.
The gross unrecognized tax benefits increased by approximately $111.9 million during fiscal 2025 resulting in gross unrecognized tax benefits of $173.7 million as of October 31, 2025. A reconciliation of the beginning and ending balance of gross unrecognized tax benefits is summarized as follows:
As of October 31,
20252024
 (in thousands)
Beginning balance$61,854 $64,880 
Increases in unrecognized tax benefits related to prior year tax positions22,568 1,106

Increases in unrecognized tax benefits acquired79,321 161 
Changes in unrecognized tax benefits due to foreign currency translation102 690 
Ending balance$173,734 $61,854 
As of October 31, 2025 and 2024, approximately $173.7 million and $61.9 million, respectively, of the unrecognized tax benefits would affect our effective tax rate if recognized upon resolution of the uncertain tax positions.
Interest and penalties related to estimated obligations for tax positions taken in our tax returns are recognized as a component of income tax expense (benefit) in the consolidated statements of income and totaled approximately $(0.2) million, $(1.0) million and $(10.6) million for fiscal years 2025, 2024 and 2023, respectively. As of October 31, 2025 and 2024, the combined amount of accrued interest and penalties related to tax positions taken on our tax returns were approximately $0.9 million and $1.1 million, respectively.
The timing of the resolution of income tax examinations, and the amounts and timing of various tax payments that are part of the settlement process, are highly uncertain. Variations in such amounts and/or timing could cause large fluctuations in the balance sheet classification of current and non-current assets and liabilities. During the next 12 months, it is reasonably possible that certain audits and ongoing tax litigation will be resolved, or that the statute of limitations on certain state and foreign income and withholding taxes will expire, or both. Given the uncertainty as to ultimate settlement terms, the timing of payment and the impact of such settlements on other uncertain tax positions, we estimate a potential decrease in underlying unrecognized tax benefits to be between $0.0 and $29.0 million.
We and/or our subsidiaries remain subject to tax examination in the following jurisdictions:

One of our Korean subsidiaries, Ansys Korea, is currently involved in various stages of Tax Tribunal and Korea's High Court appeals regarding Korea's National Tax Service assessments of withholding taxes against Ansys Korea
for calendar tax years 2017-2023. In connection with this matter, we have recorded the net impact of the unrecognized tax benefit and offsetting foreign tax credit.
We are under examinations by the tax authorities in certain jurisdictions. No material assessments have been proposed in these examinations.
Legislative Developments
On July 4, 2025, U.S. President Donald J. Trump signed H.R. 1, the One Big Beautiful Bill Act (OBBB) into law. The OBBB includes many changes to corporate income tax law, including expensing for domestic research expenditures commencing in fiscal 2026 and changes to foreign-derived intangible income deduction in fiscal 2027. We are currently evaluating the impacts of OBBB.
Effective our fiscal 2024, we are subject to the new 15% corporate alternative minimum tax (CAMT) enacted as part of the Inflation Reduction Act of 2022 (the IR Act). As of October 31, 2025, this has not had an impact on our consolidated financial statements. We will monitor regulatory developments and will continue to evaluate the impact, if any, of the CAMT.
The IR Act imposes a 1% excise tax on the fair market value of stock repurchases made by covered corporations after December 31, 2022. In general, the total taxable value of shares repurchased is reduced by the fair market value of any newly issued shares during the taxable year. As of October 31, 2025, this has not had an impact on our consolidated financial statements.
On June 27, 2024, California enacted SB-167, which suspends the use of California net operating loss and limits the use of California research tax credits to $5 million for our fiscal 2025-2027. On June 29, 2024, California enacted SB-175, which provides a refund mechanism effective beginning in our fiscal 2025 for the incremental tax that was paid as a result of SB-167.
The Organisation for Economic Co-operation and Development (the OECD) has model rules for a global minimum tax framework, which is a two-pillar solution to address tax challenges arising from digitalization of the economy. This two-pillar solution includes the Pillar Two Model Rules (Pillar 2) which define global minimum tax rules and imposes a 15% minimum tax rate. Various countries have started to enact new laws related to Pillar 2, including certain new laws effective beginning in fiscal 2025. As of fiscal 2025, the impact of Pillar 2 is not material.

Segment Reporting [Abstract]  
Segment Disclosure Segment Disclosure
Segment reporting is based upon the “management approach,” i.e., how management organizes our operating segments for which separate financial information is (1) available and (2) evaluated regularly by the CODM in deciding how to allocate resources and in assessing performance. Our CODM is our CEO.
We have two reportable segments: (1) Design Automation, which includes our advanced silicon design, verification products and services, Ansys products, system integration products and services, digital, custom and field programmable gate array (FPGA) IC design software, verification software and hardware products, manufacturing software products and other; and (2) Design IP, which includes our interface, foundation, security, and embedded processor IP, IP subsystems, and IP implementation services.
We completed our assessment of our organizational structure after the Ansys Merger and concluded that Ansys is included within our Design Automation segment based on how our CODM evaluates the financial results in making operational decisions, allocating resources and assessing performance.
The financial information provided to and used by the CODM to assist in making operational decisions, allocating resources, and assessing performance includes consolidated financial information as well as revenue, adjusted operating income, and adjusted operating margin information for the Design Automation, and Design IP segments, accompanied by disaggregated information relating to revenue by geographic region.
The Software Integrity business constituted its own reportable segment under Topic 280. In accordance with applicable accounting guidance, the results of the Software Integrity business were presented as discontinued operations in the consolidated statements of income and, as such, have been excluded from both continuing operations and segment results for all periods presented. See Note 3. Discontinued Operations of the Notes to Consolidated Financial Statements in this Annual Report.

Restructuring and Related Activities [Abstract]  
Restructuring Charges Restructuring Charges
In the first quarter of fiscal 2023, we initiated a restructuring plan for involuntary employee terminations as part of a business reorganization (the 2023 Plan). The 2023 Plan was substantially completed in the third quarter of fiscal 2023 and total charges under the 2023 Plan consisting primarily of severance costs and facility exit costs were $77.0 million, of which $23.9 million were related to discontinued operations.
During fiscal 2025, we made payments of $0.8 million related to continuing operations under the 2023 Plan. As of October 31, 2025, $0.7 million were recorded in accounts payable and accrued liabilities, and the remaining outstanding restructuring related liabilities of $3.1 million were recorded in other long-term liabilities in the consolidated balance sheets.
During fiscal 2024, we made payments of $3.6 million related to continuing operations and $0.5 million related to discontinued operations under the 2023 Plan. As of October 31, 2024, the payroll and related benefits liabilities of $0.8 million were recorded in accounts payable and accrued liabilities, and the remaining outstanding restructuring related liabilities of $3.8 million were recorded in other long-term liabilities in the consolidated balance sheets.
During fiscal 2023, we recorded restructuring charges related to continuing operations of $53.1 million and made payments of $44.9 million under the 2023 Plan. We recorded restructuring charges related to discontinued operations of $23.9 million and made payments of $23.4 million under the 2023 Plan. As of October 31, 2023, the payroll and related benefits liabilities related to continuing operations of $3.7 million were recorded in accounts payable and accrued liabilities, and the remaining outstanding restructuring related liabilities of $4.5 million were recorded in other long-term liabilities in the consolidated balance sheets. The payroll and related benefits liabilities related to discontinued operations were $0.5 million.
Subsequent event
In November 2025, we initiated a restructuring plan for involuntary employee terminations as part of a business reorganization (the 2026 Plan) upon approval by the Board of Directors. The 2026 Plan will allow us to invest in key growth opportunities and drive business efficiencies following the completion of the Ansys Merger. Total charges under the 2026 Plan are expected to be in the range of $300.0 million and $350.0 million, and will consist primarily of severance costs, other one-time termination benefits and facility exit costs. The 2026 Plan is anticipated to be completed by the end of fiscal 2027, with majority of the workforce reduction in fiscal 2026.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]
We recognize the importance of assessing, identifying, and managing material risks associated with cybersecurity threats, as such term is defined in Item 106(a) of Regulation S-K. These risks include, among other things, operational risks; intellectual property theft; fraud; extortion; harm to employees or customers; violation of privacy or security laws and other litigation and legal risk; and reputational risks.
We maintain a cybersecurity program and incident response plan to coordinate the activities we take to protect against, detect, respond to and remediate cybersecurity incidents, as such term is defined in Item 106(a) of Regulation S-K, as well as to comply with potentially applicable legal obligations and mitigate brand and reputational damage.
We have implemented cybersecurity processes, technologies, and controls to aid in our efforts to identify, assess, and manage material risks, as well as to test and improve our incident response plan. Our approach includes, among other things:
Security and privacy reviews designed to identify risks from new features, software, suppliers, and vendors;
A vulnerability management program designed to identify software vulnerabilities;
A variety of tools designed to monitor our networks, systems, and data for suspicious activity;
An internal red team program that simulates cyber threats, enhancing our ability to fix vulnerabilities before they are exploited by threat actors;
A threat intelligence program designed to model and research our adversaries;
Products and services to structure, test, and assess the rigor of our software security practices;
A variety of privacy, cybersecurity, and incident response trainings and simulations, including mandatory yearly training for all employees, additional training for all Information Technology and Information Security personnel, and regular controlled penetration testing and cyber incident exercises to test the robustness of our data security protections and incident response readiness;
For suppliers and service providers, pre-engagement risk-based diligence, contractual security and notification provisions, and ongoing monitoring as appropriate; and
Maintaining cyber liability insurance that covers certain liabilities related to data breaches and related incidents.
Synopsys’ cybersecurity policies and procedures are intended to align with multiple industry-recognized frameworks, including the National Institute of Standards and Technology Cyber Security Framework (NIST CSF) and the ISO/International Electrotechnical Commission (IEC) 27001 Information Security Management Framework. In addition, some Synopsys products are ISO27001 and/or SOC2 Type 2 certified. Our internal audit department regularly assesses our conformity with these frameworks. We track our NIST CSF implementation through regular third-party maturity assessments, which provide the basis for establishing performance goals for the coming period. We also closely monitor the ever-changing landscape of related laws and regulations and regularly update our policies and processes to promote continued compliance.
Our process for identifying and assessing material risks from cybersecurity threats operates alongside our broader overall risk assessment process. As part of this process, appropriate personnel will collaborate with subject matter specialists, as necessary, to gather insights for identifying and assessing material cybersecurity threat risks, their severity, and potential mitigations. As part of the above approach and processes, we regularly engage with assessors, consultants, auditors, and other third-parties to help identify areas for continued focus, improvement and/or compliance.
Since 2015, Synopsys is not aware of any material information security breaches and has not made any associated penalties/settlements, and the expenses we have incurred from cybersecurity incidents were immaterial. This
includes penalties and settlements, of which there were none. During the same time period, while some of our suppliers have experienced security breaches, none of these breaches have had a material impact on Synopsys.
In our risk factors, we describe whether and how risks from identified cybersecurity threats, including as a result of any previous cybersecurity incidents, have materially affected or are reasonably likely to materially affect us, including our business strategy, results of operations or financial condition. See our risk factor disclosures in Part I, Item 1A of this Annual Report.

Summary of Significant Accounting Policies and Basis of Presentation (Policies)
12 Months Ended
Oct. 31, 2025
Accounting Policies [Abstract]  
Fiscal Year End Historically, our fiscal years have been 52- or 53-week periods ending on the Saturday nearest to October 31. Fiscal 2024 was a 53-week year ended on November 2, 2024, and fiscal 2023 was a 52-week year ended on October 28, 2023.
We have changed our fiscal year end from the Saturday nearest to October 31 and consisting of 52 or 53 fiscal weeks to a fiscal year end of October 31 each year. The fiscal year change became effective with our fiscal 2025, which began on November 3, 2024. Our fiscal quarters end on January 31, April 30, July 31 and October 31 of each year.
Our results of operations for the fiscal 2025, fiscal 2024 and fiscal 2023 included 363 days, 371 days, and 364 days respectively. For presentation purposes, the consolidated financial statements and accompanying notes refer to the closest calendar month end.
Principles of Consolidation The consolidated financial statements include our accounts and the accounts of our wholly and majority-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates
Use of Estimates. To prepare financial statements in conformity with U.S. GAAP, management must make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates and could have a material impact on our operating results and financial position.
Acquisition of Ansys and Business Combinations
Acquisition of Ansys. On July 17, 2025 (the Acquisition Date), we completed the acquisition of ANSYS, Inc. (Ansys), a provider of broad engineering simulation and analysis software and services for $199.91 in cash and 0.3399 of a share of our common stock in exchange for each ordinary share of Ansys for a total consideration of $34.9 billion.
We accounted for the acquisition of Ansys by applying the acquisition method of accounting for business combinations. The consolidated financial statements include the financial results of Ansys prospectively from the Acquisition Date.
Business Combinations. We allocate the purchase price of acquired companies to the tangible and intangible assets acquired and liabilities assumed based on their acquisition-date fair values with the exception of contract assets and contract liabilities (deferred revenue) which are recognized and measured on the acquisition date in accordance with our “Revenue Recognition” policy, as if we had originated the contracts. The excess of the purchase consideration over the fair value of these identifiable assets and liabilities is recorded as goodwill. Acquisition-related expenses are recognized separately from the business combination and are expensed as incurred. We include the results of operations of the businesses that are acquired from the acquisition date.
Cash Equivalents and Short-term Investments Cash Equivalents and Short-term Investments. We consider all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents, as well as time deposits which can be withdrawn at any time without penalty to be cash equivalents. Our investments in debt securities with remaining maturities greater than three months at the date of purchase are designated as available-for-sale securities as we may convert these investments into cash at any time to fund general operations, and included in short-term investments in the consolidated balance sheets. Our debt securities generally have an effective maturity term of less than three years and are carried at fair value, with unrealized gains and losses included in the consolidated balance sheets as a component of accumulated other comprehensive income (loss). For available-for-sale debt securities in an unrealized loss position, we evaluate whether a current expected credit loss exists based on available information relevant to the credit rating of the security, current economic conditions and reasonable and supportable forecasts. The allowance for credit loss is recorded in other income (expense), net, in the consolidated statements of income, not to exceed the amount of the unrealized loss. Any excess unrealized loss other than the credit loss is recognized in accumulated other comprehensive income or loss in the stockholders' equity section of the consolidated balance sheets. The cost of securities sold is based on the specific identification method and realized gains and losses are included in other income (expense), net.
Investments in Equity Securities
Investments in Equity Securities. We hold equity securities in privately held companies for the promotion of business and strategic objectives. We account for these investments using either the measurement alternative approach when the fair value of the investment is not readily determinable and we do not have the ability to exercise significant influence, or the equity method of accounting when it is determined that we have the ability to exercise significant influence. Investments accounted for using the measurement alternative approach are initially recorded at cost and adjusted for changes in fair value from observable transactions. For investments accounted for using the equity method of accounting, we record our proportionate share of the investee’s income or loss to other income (expense), net, in our consolidated statements of income. These investments are subject to a periodic impairment review, and are included in other long-term assets in the consolidated balance sheets.
Accounts Receivable, Net
Accounts Receivable, Net. The balances consist of billed accounts receivable and current portion of unbilled accounts receivable. Trade accounts receivables are recorded at the invoiced amount and do not bear interest.
Allowance for Credit Losses Allowance for Credit Losses. We maintain an allowance for credit losses for expected uncollectible accounts receivable and contract assets, which is recorded as an offset to accounts receivable or contract assets and provisions for credit losses are recorded in general and administrative expense in the consolidated statements of income. The allowance for current expected credit losses is based on a review of customer accounts and considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. The allowance for credit losses is reviewed on a quarterly basis to assess the adequacy of the allowance.
Inventories
Inventories. Inventories are computed at standard costs which approximate actual costs, on a first-in, first-out basis and valued at the lower of cost or net realizable value. Inventories primarily include components and finished goods for complex emulation and prototyping hardware systems. The valuation process includes a review of the forecasts based upon future demand and market conditions. Inventory provisions are recorded when gross inventory may be in excess of anticipated demand or considered obsolete. Inventory provisions are impacted by market and economic conditions, technology changes, new product introductions and changes in strategic direction, and require estimates that may include uncertain elements.
Fair Values of Financial Instruments Fair Values of Financial Instruments. Our cash equivalents, short-term investments, marketable securities and foreign currency contracts are carried at fair value. The fair value of our accounts receivable and accounts payable approximates the carrying amount due to their short duration. Non-marketable equity securities are accounted for using either the measurement alternative or equity method of accounting. We perform periodic impairment analysis on these non-marketable equity securities. The carrying amount of the short-term and long-term debt approximates the estimated fair value.
Foreign Currency Contracts
Foreign Currency Contracts. We operate internationally and are exposed to potentially adverse movements in currency exchange rates. We enter into hedges in the form of foreign currency forward contracts to reduce our exposure to foreign currency rate changes on non-functional currency denominated forecasted transactions and balance sheet positions. The assets or liabilities associated with the forward contracts are recorded at fair value in other current assets or accrued liabilities in the consolidated balance sheets.
The accounting for gains and losses resulting from changes in fair value depends on the use of the foreign currency forward contract and whether it is designated and qualifies for hedge accounting.
Concentration of Credit Risk
Concentration of Credit Risk. Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash equivalents, short-term investments, foreign currency contracts, and trade accounts receivable. We maintain cash equivalents primarily in highly rated taxable and tax-exempt money market funds located in the U.S. and in various overseas locations. Our short-term investments include a variety of financial instruments, such as corporate debt and municipal securities, U.S. Treasury and Government agency securities. By policy, we limit the amount of credit exposure with any one issue, issuer and type of instrument.
We sell our products worldwide primarily to customers in the global electronics market. We perform on-going credit evaluations of our customers’ financial condition and do not require collateral. We establish reserves for potential credit losses and such losses have been within management’s expectations.
Income Taxes
Income Taxes. We account for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
We account for uncertainty in income taxes using a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining whether it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. An uncertain tax position is considered effectively settled on completion of an examination by a taxing authority if certain other conditions are satisfied.
Property and Equipment Property and Equipment. Property and equipment is recorded at cost less accumulated depreciation. Assets, excluding land, are depreciated using the straight-line method over their estimated useful lives.
Leases
Leases. We determine if an arrangement is a lease at inception of the contract, which is the date on which the terms of the contract are agreed to, and the agreement creates enforceable rights and obligations. A contract is or contains a lease when we have the right to control the use of an identified asset for a period of time. The commencement date of the lease is the date that the lessor makes an underlying asset available for use by the lessee. On the commencement date, leases are evaluated for classification and assets and liabilities are recognized based on the present value of lease payments over the lease term.
The lease term used to calculate the lease liability includes options to extend or terminate the lease when it is reasonably certain that the option will be exercised. The right of use (ROU) asset is initially measured as the amount of lease liability, adjusted for any initial lease costs, prepaid lease payments and any lease incentives. Variable lease payments, consisting primarily of reimbursement of costs incurred by lessors for common area maintenance, real estate taxes and insurance, are not included in the lease liability and are recognized as they are incurred.
As most of our leases do not provide an implicit rate, we use the incremental borrowing rate at lease commencement to measure ROU assets and lease liabilities. We use a benchmark senior unsecured yield curve for debt instruments over the similar term, and consider specific credit quality, market conditions, tenor of lease arrangements, and quality of collateral to determine the incremental borrowing rate.
Operating lease expense is generally recognized on a straight-line basis over the lease term. We have elected the practical expedient to account for the lease and non-lease components as a single lease component for the majority of our asset classes. For leases with an initial term of one year or less, we have elected not to record the ROU asset or liability.
Goodwill Goodwill. Goodwill represents the excess of the aggregate purchase price over the fair value of the net tangible and identifiable intangible assets acquired by us. All goodwill acquired in a business combination is assigned to one or more reporting units as of acquisition date. We have two reportable segments, and reporting units are determined to be the same as reportable segments. The carrying amount of goodwill at each reporting unit is tested for impairment annually on the first day of the fourth fiscal quarter, or more frequently if facts and circumstances warrant a review. We perform either a qualitative or quantitative assessment for goodwill impairment test. When a quantitative goodwill impairment assessment is performed, we use an income approach based on discounted cash flow analysis, a market approach based on market multiples, or a combination of both. If the fair value of a reporting unit is less than its carrying value, a goodwill impairment loss is recorded for the difference.
Intangible Assets
Intangible Assets. Intangible assets consist of acquired technology, certain contract rights, customer relationships, trademarks and trade names, and capitalized software. These intangible assets are acquired through business combinations, direct purchases, or internally developed capitalized software. Intangible assets are amortized on a straight-line basis over their estimated useful lives which range from one to twenty-three years.
We review the carrying values of long-lived assets including intangible assets whenever events or changes in circumstances indicate that the carrying value may not be fully recoverable. Recoverability of long-lived assets is
measured by comparing the carrying value of such asset group to the future undiscounted cash flows that asset group is expected to generate. If the undiscounted future cash flow is less than the carrying amount of the asset group, we recognize an impairment loss based on the excess of the carrying amount over the fair value of the asset group.
Redeemable Non-controlling Interest Redeemable Non-controlling Interest. Non-controlling interest that is not solely redeemable within our control is reported as temporary equity in our consolidated balance sheets. The carrying value of the redeemable non-controlling interest equals the redemption value at the end of each reporting period, after giving effect to the change from the net income (loss) attributable to the redeemable non-controlling interest. We remeasure the redemption value of the non-controlling interest on a quarterly basis and changes in the estimated redemption value are recognized through retained earnings and may also impact the net income or loss attributable to common stockholders of Synopsys if the redemption value falls below a stated threshold.
Revenue Recognition
Revenue Recognition. We recognize revenue for the transfer of services or products to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those services or products. The principle is achieved through the following five-step approach:
Identification of the contract, or contracts, with the customer
Identification of the performance obligation in the contract
Determination of the transaction price 
Allocation of the transaction price to the performance obligations in the contract 
Recognition of revenue when, or as, we satisfy a performance obligation 
Nature of Products and Services
We generate revenue from the licensing of our EDA software, IP products and S&A software solutions, as well as sale of hardware products, and maintenance and services. The various types are set forth below.
Electronic Design Automation
Software license revenue consists of fees associated with the licensing of our software and Ansys semiconductor products primarily through Technology Subscription License (TSL) contracts. TSLs are time-based licenses for a finite term and generally provide the customer with limited rights to receive, or to exchange certain quantities of licensed software for, unspecified future technology. The majority of our arrangements are TSLs due to the nature of our business and customer requirements. In addition to the licenses, the arrangements also include: post-contract customer support, which includes providing frequent updates and upgrades to maintain the utility of the software due to rapid changes in technology; other intertwined services such as multiple copies of the tools; assisting our customers in applying our technology in the customers' development environment; and rights to remix licenses for other licenses. Payments are generally received in equal or near equal installments over the term of the arrangement. We have concluded that our software licenses in TSL contracts are not distinct from our obligation to provide unspecified software updates to the licensed software throughout the license term. Such updates represent inputs to a single, combined performance obligation, commencing upon the later of the arrangement effective date or transfer of control to the software license. Remix rights are not an additional promised good or service in the contract, and where unspecified additional software product rights are part of the contract with the customer, such rights are accounted for as part of the single performance obligation that includes the licenses, updates, and technical support because such rights are provided for the same period of time and have the same pattern of transfer to the customer over the duration of the subscription term. 
Design IP Products
We generally license IP under nonexclusive license agreements that provide usage rights for specific applications. Additionally, for certain IP license agreements, royalties are collected as customers sell their own products that incorporate our IP. These arrangements generally have two distinct performance obligations that consist of transferring the licensed IP and the post contract support service. Support services consist of a stand-ready
obligation to provide technical support and software updates over the support term. Revenue allocated to the IP license is recognized at a point in time upon the later of the delivery date or the beginning of the license period, and revenue allocated to support services is recognized ratably over the support term. Royalties are recognized as revenue is earned, generally when the customer sells its products that incorporate our IP. 
Simulation and Analysis
S&A solutions allow engineers to virtually test and optimize designs across various physics domains, such as structural analysis, thermal analysis, and computational fluid dynamics (CFD). S&A software solutions are offered as subscription solutions and also as perpetual licenses. Software subscription arrangements include bundles of time-based software licenses with support services, which includes rights to technical support and software updates that are provided over the support term and are transferred to the customer over time. In such subscription arrangements, the updates to time-based software licenses are not considered integral to maintaining the utility of the software. We consider the license and support services as separate performance obligations. In these instances, we allocate the total consideration received for the revenue arrangement to the separate performance obligations based on the standalone selling prices of the time-based software license and support service. The time-based software license revenue is presented as upfront products revenue, recognized at a point of time upon the later of the delivery date or the beginning of the license period, and the revenue related to the support service is presented as maintenance and service revenue and is recognized over the term of the arrangement. Perpetual license arrangements typically include a perpetual license sold with support services, which includes a stand-ready obligation to provide technical support and software updates over the support term. We allocate the total consideration received for the bundled perpetual and support service arrangements based on the standalone selling prices of the perpetual license and support service. Revenue from perpetual licenses is presented as upfront product revenue and is recognized at a point in time upon the later of the delivery date or the beginning of the license period. Revenue from support service is classified as maintenance and service revenue and is recognized ratably over the term of the contract, as we satisfy the support service performance obligation.
Hardware
We generally have two performance obligations in arrangements involving the sale of hardware products. The first performance obligation is to transfer the hardware product, which includes embedded software integral to the functionality of the hardware product. The second performance obligation is to provide maintenance on the hardware and our embedded software, including rights to technical support, hardware repairs and software updates that are all provided over the same term and have the same time-based pattern of transfer to the customer. The portion of the transaction price allocated to the hardware product is recognized as revenue at a point in time when control of the hardware is transferred to the customer. We have concluded that control generally transfers upon shipment because the customer has the ability to direct the use of the asset and an obligation to pay for the hardware. The portion of the transaction price allocated to maintenance is recognized as revenue that is ratable over the maintenance term.
Professional Services
Our arrangements often include service elements other than maintenance and support services. These services include training, design assistance, and consulting. These services are generally performed on a time and materials basis, and are recognized over time, as the customer simultaneously receives and consumes the benefit provided. Certain arrangements also include the customization or modification of licensed IP. Revenue from these contracts is recognized over time as the services are performed, when the development is specific to the customer’s needs and we have enforceable rights to payment for performance completed. Inputs such as costs incurred and hours expended are used in order to measure progress of performance. We have a history of accurately estimating project status and the costs necessary to complete projects. A number of internal and external factors can affect these estimates, including labor rates, utilization and efficiency variances, specification and testing requirement changes, and changes in customer delivery priorities. Payments for services are generally due upon milestones in the contract or upon consumption of the hourly resources.
Flexible Spending Accounts
Our customers frequently enter into non-cancelable Flexible Spending Account arrangements (FSA) whereby the customer commits to a fixed dollar amount over a specified period of time that can be used to purchase from a list of our products or services. These arrangements do not meet the definition of a revenue contract until the customer
executes a separate order (pulldown request) to identify the required products and services that they are purchasing. The combination of the FSA arrangement and the subsequent order creates enforceable rights and obligations, thus meeting the definition of a revenue contract. Each separate order under the agreement is treated as an individual contract and accounted for based on the respective performance obligations included within the pulldown requests.
Significant Judgments
Our contracts with customers often include promises to transfer multiple products and services to a customer. Customers can negotiate for a broad portfolio of solutions, and favorable terms along with future purchase options to manage their overall costs. Analysis of the terms and conditions in these contracts and their effect on revenue recognition may require significant judgment. We have concluded that (1) our EDA software licenses in TSL contracts and software licenses in certain Ansys' semiconductor industry subscription products are not distinct from our obligation to provide unspecified software updates to the licensed software throughout the license term, because those promises represent inputs to a single, combined performance obligation, and (2) where unspecified additional software product rights are part of the contract with the customer, such rights are accounted for as part of the single performance obligation that includes the licenses, updates, and technical support, because such rights are provided for the same period of time and have the same time-based pattern of transfer to the customer. In reaching this conclusion, we considered the nature of the obligation to customers, which is to provide an ongoing right to use the most up to date and relevant software. As EDA customers operate in a rapidly changing and competitive environment, satisfying the obligation requires providing critical updates to the existing software products, including ongoing iterative interaction with customers to make the software relevant to customers’ ability to meet the time to go to market with advanced products.
Software subscription arrangements for S&A solutions include bundles of time-based software licenses with support services, which includes rights to technical support and software updates that are provided over the support term and are transferred to the customer over time. We have concluded that the updates to time-based software licenses are not considered integral to maintaining the utility of the software and hence the license and support services as separate performance obligations. We also license S&A software on a perpetual basis with support services, which includes a stand-ready obligation to provide technical support and software updates over the support term. We allocate the total consideration received for the bundled perpetual and support service arrangements based on the standalone selling prices of the perpetual license and support service.
Our contracts with customers can involve hundreds of products and various license rights. Customers often negotiate a broad portfolio of solutions, and favorable terms along with future purchase options to manage their overall costs. Determining whether the purchase options are considered distinct performance obligations that should be accounted for separately as material rights versus combined together may require significant judgment.
Judgment is also required to determine the standalone selling price (SSP) for each distinct performance obligation. For non-software performance obligations (IP, Hardware, and services), SSP is established based on observable prices of products and services sold separately. SSP for license (and related updates and support) in a contract with multiple performance obligations is determined by applying a residual approach whereby all other non-software performance obligations within a contract are first allocated a portion of the transaction price based upon their respective SSP, using observable prices, with any residual amount of the transaction price allocated to the license because we do not sell the license separately, and the pricing is highly variable. For S&A product subscription sales, we use all information reasonably available to us to determine the estimated SSP of time-based software license and support services.
Contract Balances
The timing of revenue recognition may differ from the timing of invoicing customers, resulting in receivables, contract assets, or contract liabilities (deferred revenue) in our consolidated balance sheets. For specific software, hardware, and IP agreements with payment plans, we record an unbilled receivable associated with revenue recognized upon transfer of control, as it holds an unconditional right to invoice and receive payment in the future for those transferred products or services. A contract asset is recorded when revenue is recognized before we have the unconditional right to invoice or retain performance risk concerning that performance obligation. These contract assets transition to receivables when the rights become unconditional, generally upon the completion of a milestone. A deferred revenue is recorded when revenue is recognized subsequent to invoicing.
Warranties and Indemnities
Warranties and Indemnities
Warranties. We generally warrant our products to be free from defects in media and to substantially conform to material specifications for a period of 90 days for our software products and for up to six months for our hardware products.
Indemnities. In addition to such warranties, in certain cases, we provide our customers with limited indemnification with respect to claims that their use of our software products infringes on patents, copyrights, trademarks or trade secrets. We are unable to estimate the potential impact of these commitments on the future results of operations.
Net Income Per Share Net Income Per Share. We compute basic net income per share by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net income per share reflects the dilution from potential common shares outstanding such as stock options and unvested restricted stock units (RSUs) and awards during the period using the treasury stock method.
Foreign Currency Translation
Foreign Currency Translation. The functional currency of the majority of our active foreign subsidiaries is the foreign subsidiary’s local currency. Assets and liabilities that are not denominated in the functional currency are remeasured into the functional currency with any related gains or losses recorded in earnings. We translate assets and liabilities of our non-U.S. dollar functional currency foreign operations into the U.S. dollar reporting currency at exchange rates in effect at the balance sheet date. We translate income and expense items of such foreign operations into the U.S. dollar reporting currency at average exchange rates for the period. Accumulated translation adjustments are reported in stockholders’ equity, as a component of accumulated other comprehensive income (loss).
Recently Adopted Accounting Pronouncements and Recent Accounting Pronouncements Not Yet Adopted
Recently Adopted Accounting Pronouncements
In June 2022, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, which applies to all equity securities measured at fair value that are subject to contractual sale restrictions. This change prohibits entities from taking into account contractual restrictions on the sale of equity securities when estimating fair value and introduces required disclosures for such transactions. We adopted the standard as of the beginning of fiscal 2025 on a prospective basis and the adoption did not have a material impact on our consolidated financial statements.
In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The ASU expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the Chief Operating Decision Maker (CODM) and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. The ASU is effective for our annual reports beginning in fiscal 2025 and interim period reports beginning in fiscal 2026. We adopted the standard during fiscal 2025, on a retrospective basis, and the adoption provided more granular disclosure of significant operating expenses within our segment disclosure. See Note 19. Segment Disclosure of the Notes to Consolidated Financial Statements in this Annual Report for further details.
Recent Accounting Pronouncements Not Yet Adopted
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which enhances the transparency and decision usefulness of income tax disclosures primarily through changes to the rate reconciliation and income taxes paid information. The ASU will be effective for us beginning in fiscal 2026 and will be applied on a prospective basis. Early adoption is permitted. We are currently evaluating the impact of this ASU on our consolidated financial statements and related disclosures.
In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income-Expense Disaggregation (Subtopic 220-40): Disaggregation of Income Statement Expenses. The ASU requires the disclosure of additional information related to certain costs and expenses, including amounts of inventory purchases, employee compensation, and depreciation and amortization included in each income statement line item. The ASU also requires disclosure of the total amount of selling expenses and our definition of selling expenses. The ASU will be effective for our annual reports beginning in fiscal 2028, and interim period reports
beginning in fiscal 2029 either on a prospective or retrospective basis. Early adoption is permitted. We are currently evaluating the impact of adopting this ASU on our consolidated financial statements and related disclosures.
In July 2025, the FASB issued ASU 2025-05, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. The ASU allows companies to apply a practical expedient when estimating credit losses on current accounts receivable and contract assets. The ASU will be effective for us beginning in fiscal 2027 and will be applied on a prospective basis. Early adoption is permitted. We are currently evaluating the impact of adopting this ASU on our consolidated financial statements and related disclosures.
In September 2025, the FASB issued ASU 2025-06, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which modernizes the accounting for internal-use software costs and clarifies the criteria for capitalization. The ASU will be effective for us beginning in fiscal 2029, either on a prospective, retrospective, or a modified basis. Early adoption is permitted. We are currently evaluating the impact of adopting this ASU on our consolidated financial statements and related disclosures.
Restricted cash
Restricted cash
We include amounts generally described as restricted cash in cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts shown in the consolidated statements of cash flows. Restricted cash is primarily associated with deposits for office leases and employee loan programs.
Fair Value Measurements
ASC 820-10, Fair Value Measurements and Disclosures, defines fair value, establishes guidelines and enhances disclosure requirements for fair value measurements. The accounting guidance requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The accounting guidance also establishes a fair value hierarchy based on the independence of the source and objective evidence of the inputs used. There are three fair value hierarchies based upon the level of inputs that are significant to fair value measurement:
Level 1—Observable inputs that reflect quoted prices (unadjusted) for identical instruments in active markets;
Level 2—Observable inputs other than quoted prices for identical instruments in active markets, quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in inactive markets, and model-driven valuations in which all significant inputs and significant value drivers are observable in active markets; and
Level 3—Unobservable inputs derived from fair valuation techniques in which one or more significant inputs or significant value drivers are unobservable.
On a recurring basis, we measure the fair value of certain assets and liabilities, which include cash equivalents, short-term investments, marketable securities, non-qualified deferred compensation plan assets, contingent consideration receivable, and foreign currency derivative contracts.
Our cash equivalents, short-term investments and marketable securities are classified within Level 1 or Level 2 because they are valued using quoted market prices in an active market or alternative independent pricing sources and models utilizing market observable inputs.
Our non-qualified deferred compensation plan assets consist of money market and mutual funds invested in domestic and international marketable securities that are directly observable in active markets and are therefore classified within Level 1.
Our foreign currency derivative contracts are classified within Level 2 because these contracts are not actively traded and the valuation inputs are based on quoted prices and market observable data of similar instruments.
Our borrowings under our Credit and Term Loan facilities are classified within Level 2 because these borrowings are not actively traded and have a variable interest rate structure based upon market rates currently available to us for debt with similar terms and maturities. See Note 10. Senior Notes, Bridge Commitment Letter, Term Loan and Revolving Credit Facilities of the Notes to Consolidated Financial Statements in this Annual Report for more information on these borrowings.
Our contingent consideration receivable, which was recorded in connection with the Software Integrity Divestiture, was classified within Level 3 because it was estimated using significant inputs that were not observable in the market. See Note 3. Discontinued Operations of the Notes to Consolidated Financial Statements in this Annual Report for additional information.

Total identified intangible assets
$12,990,000 
(1) Core/developed technology was identified from the products of Ansys and its preliminary fair value was determined using the relief-from-royalty method under the income approach. The relief-from-royalty method applies a royalty rate to projected income to quantify the benefit of owning the intangible asset rather than paying a royalty for use of the asset. The discount rate was determined at the time of measurement based on an analysis of the implied internal rate of return of the transaction, weighted-average cost of capital, and weighted-average return on assets. The economic useful life was determined based on the technology cycle related to each developed technology, as well as the cash-flows over the forecast period.

(2) Customer relationships represent the preliminary fair value of future projected revenue that will be derived from sales of products to existing Ansys customers. The fair value was determined using the multi-period excess earnings method under the income approach, which involves isolating the net earnings attributable to the asset being measured based on present value of the incremental after-tax cash flows (excess earnings) attributable solely to the intangible asset over its remaining useful life. The economic useful life was determined based on historical customer turnover rates and the useful life of developed technology.

(3) Contract rights intangible, which represents contracted but unsatisfied or partially unsatisfied performance obligations, primarily relates to the dollar value of purchase arrangements with customers. The preliminary fair value was determined using the multi-period excess earnings method under the income approach. The economic useful life is based on the time to fulfill the outstanding order backlog obligation.

(4)Trademarks and trade names refers to Ansys brand assets. The preliminary fair value was determined by applying the relief-from-royalty method under the income approach. This method is based on the application of a royalty rate to forecasted revenue attributable to Ansys brand assets. The economic useful life was determined based on the expected usage period of the brand assets and the anticipated cash flows over the forecast period.
