Fair value of financial instruments	Inputs to valuation techniques are observable or unobservable.

This hierarchy requires Cadence to minimize the use of unobservable inputs and to use observable market data, if available, when determining fair value. Cadence recognizes transfers between levels of the hierarchy based on the fair values of the respective financial instruments at the end of the reporting period in which the transfer occurred.
Contingencies	At least quarterly, Cadence reviews the status of each significant matter and assesses its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount or the range of loss can be estimated, Cadence accrues a liability for the estimated loss. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based on Cadence’s judgments using the best information available at the time. As additional information becomes available, Cadence reassesses the potential liability related to pending claims and legal proceedings and may revise estimates.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

The condensed consolidated financial statements included in this Quarterly Report on Form 10-Q have been prepared by Cadence Design Systems, Inc. (“Cadence”) without audit, pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations.

Use of estimates

Preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Risks and Uncertainties

Because Cadence operates globally, its business is subject to the effects of economic downturns or recessions in the regions in which it does business, volatility in foreign currency exchange rates relative to the U.S. dollar, inflation, changing interest rates, expanded trade control laws and regulations, imposition of new or higher tariffs and geopolitical conflicts.

Cadence has been impacted by the continued expansion of trade control laws and regulations, including certain export control restrictions concerning advanced node IC production in China, the inclusion of additional Chinese technology companies on the Bureau of Industry and Security (“BIS”) “Entity List” and regulations governing the sale of certain technologies.

On May 23, 2025, BIS informed Cadence that a license was required for the export, re-export or in-country transfer of EDA software and technology classified under Export Control Classification Numbers (ECCNs) 3D991 and 3E991 on the Commerce Control List (“EDA Software and Technology”), when a party to the transaction is located in China or is a Chinese “military end user” wherever located.

Recently Adopted Accounting Standards

Segment Reporting

In November 2023, the Financial Accounting Standards Board (“FASB”), issued Accounting Standards Update (“ASU”) No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” intended to improve reportable segment disclosure requirements, primarily through enhanced annual and interim disclosures for significant segment expenses. Cadence adopted this ASU retrospectively during fiscal 2024 for its Annual Report. For interim disclosures required by this ASU, see Note 15 in the notes to condensed consolidated financial statements.

New Accounting Standards Not Yet Adopted

Income Taxes

In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires disclosure of disaggregated income taxes paid, prescribes standard categories for the components of the effective tax rate reconciliation, and modifies other income tax-related disclosures. This standard is effective for fiscal years beginning after December 15, 2024, and may be applied on a retrospective or prospective basis. Cadence plans to adopt this standard in connection with its annual report for fiscal 2025 and is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures.

Income Statement - Expense Disaggregation Disclosure

In November 2024, the FASB issued ASU No. 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures,” which requires additional disclosure of certain costs and expenses in the notes to the financial statements. The updated standard is effective for fiscal years beginning after December 15, 2026 and interim periods beginning after December 15, 2027. Early adoption is permitted and will be applied prospectively with the option for retrospective application. Cadence is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures.

Fair value of financial instruments

Inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect Cadence’s market assumptions. These two types of inputs have created the following fair value hierarchy:

•Level 1 – Quoted prices for identical instruments in active markets;

•Level 2 – Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and

•Level 3 – Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

This hierarchy requires Cadence to minimize the use of unobservable inputs and to use observable market data, if available, when determining fair value. Cadence recognizes transfers between levels of the hierarchy based on the fair values of the respective financial instruments at the end of the reporting period in which the transfer occurred.

Contingencies

At least quarterly, Cadence reviews the status of each significant matter and assesses its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount or the range of loss can be estimated, Cadence accrues a liability for the estimated loss.
