Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies	DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION Skyworks Solutions, Inc., together with its consolidated subsidiaries (“Skyworks” or the “Company”), is empowering the wireless networking revolution. The Company’s analog and mixed-signal semiconductors are connecting people, places, and things, spanning a number of new applications within the aerospace, automotive, broadband, cellular infrastructure, connected home, defense, entertainment and gaming, industrial, medical, smartphone, tablet, and wearable markets. The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. Certain information and footnote disclosures, normally included in annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”), have been condensed or omitted pursuant to those rules and regulations. However, in management’s opinion, the financial information reflects all adjustments, including those of a normal recurring nature, necessary to present fairly the results of operations, financial position, and cash flows of the Company for the periods presented. The results of operations, financial position, and cash flows for the Company during the interim periods are not necessarily indicative of those expected for the full year. This information should be read in conjunction with the Company’s financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2022, filed with the SEC on November 23, 2022, as amended by Amendment No. 1 to such Annual Report on Form 10-K, filed with the SEC on January 27, 2023 (“2022 10-K”). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts of assets, liabilities, revenue, expenses, comprehensive income, and accumulated other comprehensive loss that are reported during the reporting period. The Company evaluates its estimates on an ongoing basis using historical experience and other factors, including the current economic environment. Judgment is required in determining the reserves for, and fair value of, items such as overall fair value assessments of assets and liabilities, particularly those classified as Level 2 or Level 3 in the fair value hierarchy, marketable securities, inventory, intangible assets associated with business combinations, share-based compensation, revenue reserves, loss contingencies, and income taxes. In addition, judgment is required in determining whether a potential indicator of impairment of long-lived assets exists and in estimating future cash flows for any necessary impairment testing. Actual results could differ significantly from these estimates.

Fair Value Disclosures [Abstract]
FAIR VALUE	4. FAIR VALUE Assets and Liabilities Measured and Recorded at Fair Value on a Recurring Basis The Company groups its financial assets and liabilities measured at fair value on a recurring basis in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are: • Level 1 - Quoted prices in active markets for identical assets or liabilities. • Level 2 - Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets with insufficient volume or infrequent transactions (less-active markets), or model-driven valuations in which all significant inputs are observable or can be derived principally from, or corroborated with, observable market data. • Level 3 - Fair value is derived from valuation techniques in which one or more significant inputs are unobservable, including assumptions and judgments made by the Company. Assets and liabilities recorded at fair value on a recurring basis consisted of the following (in millions): As of December 30, 2022 September 30, 2022 Fair Value Measurements Fair Value Measurements Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Assets Cash and cash equivalents (1) $ 819.9 $ 773.0 $ 46.9 $ — $ 566.0 $ 565.7 $ 0.3 $ — U.S. Treasury and government securities 88.3 7.8 80.5 — 13.6 3.6 10.0 — Corporate bonds and notes 83.7 — 83.7 — 0.2 — 0.2 — Municipal bonds 0.7 — 0.7 — 7.0 — 7.0 — Total assets at fair value $ 992.6 $ 780.8 $ 211.8 $ — $ 586.8 $ 569.3 $ 17.5 $ — (1) Cash equivalents included in Levels 1 and 2 consist of money market funds and corporate bonds and notes, commercial paper, and agency securities purchased with less than ninety days until maturity. Assets Measured and Recorded at Fair Value on a Nonrecurring Basis The Company’s non-financial assets and liabilities, such as goodwill, intangible assets, and other long-lived assets resulting from business combinations, are measured at fair value using income approach valuation methodologies at the date of acquisition and are subsequently re-measured if there are indicators of impairment. There were no indicators of impairment identified during the three months ended December 30, 2022. Fair Value of Debt The Company’s debt is carried at amortized cost and is measured at fair value quarterly for disclosure purposes. The estimated fair values are based on Level 2 inputs as the fair value is based on quoted prices for the Company’s debt and comparable instruments in inactive markets. The carrying value of the Term Loan approximates its fair value as the Term Loan is carried at a market observable interest rate that resets periodically. The carrying amount and estimated fair value of debt consists of the following (in millions): As of December 30, September 30, Carrying Amount Estimated Fair Value Carrying Amount Estimated Fair Value 0.90% Senior Notes due 2023 $ 499.5 $ 490.2 $ 499.2 $ 488.5 1.80% Senior Notes due 2026 497.1 442.7 496.8 431.2 3.00% Senior Notes due 2031 494.7 393.5 494.5 377.6 Total debt $ 1,491.3 $ 1,326.4 $ 1,490.5 $ 1,297.3

The Company tests its goodwill for impairment annually as of the first day of its fourth fiscal quarter and in interim periods if certain events occur indicating the carrying value of goodwill may be impaired.

During the three months ended December 30, 2022, $7.7 million of in-process research and development (“IPR&D”) assets were transferred to definite-lived intangible assets, and are being amortized over their useful lives of 12.0 years. Amortization expense related to definite-lived intangible assets was $72.0 million and $80.0 million for the three months ended December 30, 2022 and December 31, 2021, respectively. Annual amortization expense for the next five fiscal years related to definite-lived intangible assets, excluding IPR&D, is expected to be as follows (in millions): Remaining 2023 2024 2025 2026 2027 Thereafter Amortization expense $ 153.9 $ 178.3 $ 154.9 $ 127.0 $ 111.7 $ 374.1

The difference between the Company’s effective tax rate and the 21.0% United States federal statutory rate during the three months ended December 31, 2021 resulted primarily from foreign earnings taxed at rates lower than the federal statutory rate, a benefit from foreign-derived intangible income deduction (“FDII”), windfall tax deductions, and research and experimentation and foreign tax credits earned, partially offset by a tax on global intangible low-taxed income (“GILTI”), and tax expense related to a change in the reserve for uncertain tax positions.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Legal Matters From time to time, various lawsuits, claims, and proceedings have been, and may in the future be, instituted or asserted against the Company, including those pertaining to patent infringement, intellectual property, environmental hazards, product liability and warranty, safety and health, employment, and contractual matters. The semiconductor industry is characterized by vigorous protection and pursuit of intellectual property rights. From time to time, third parties have asserted and may in the future assert patent, copyright, trademark, and other intellectual property rights to technologies that are important to the Company’s business and have demanded and may in the future demand that the Company license their technology. The outcome of any such litigation cannot be predicted with certainty and some such lawsuits, claims, or proceedings may be disposed of unfavorably to the Company. Generally speaking, intellectual property disputes often have a risk of injunctive relief, which, if imposed against the Company, could materially and adversely affect the Company’s financial condition or results of operations. From time to time the Company may also be involved in legal proceedings in the ordinary course of business. The Company monitors the status of legal proceedings and other contingencies on an ongoing basis to ensure loss contingencies are recognized and/or disclosed in its financial statements and footnotes. The Company does not believe there are any pending legal proceedings that are reasonably possible to result in a material loss. The Company is engaged in various legal actions in the normal course of business and, while there can be no assurances, the Company believes the outcome of all pending litigation involving the Company will not have, individually or in the aggregate, a material adverse effect on its business or financial statements. Guarantees and Indemnities The Company has made no significant contractual guarantees for the benefit of third parties. However, the Company generally indemnifies its customers from third-party intellectual property infringement litigation claims related to its products and, on occasion, also provides other indemnities related to product sales. In connection with certain facility leases, the Company has indemnified its lessors for certain claims arising from the facility or the lease. The Company indemnifies its directors and officers to the maximum extent permitted under the laws of the state of Delaware. The duration of the indemnities varies and in many cases is indefinite. The indemnities to customers in connection with product sales generally are subject to limits based upon the amount of the related product sales and in many cases are subject to geographic and other restrictions. In certain instances, the Company’s indemnities do not provide for any limitation of the maximum potential future payments the Company could be obligated to make. The Company has not recorded any liability for these indemnities in

STOCKHOLDERS' EQUITY	10. STOCKHOLDERS’ EQUITY Stock Repurchase On January 26, 2021, the Board of Directors approved a stock repurchase program, pursuant to which the Company is authorized to repurchase up to $2.0 billion of its common stock from time to time prior to January 26, 2023, on the open market or in privately negotiated transactions, as permitted by securities laws and other legal requirements. During the three months ended December 30, 2022, the Company paid $166.2 million (including commissions) in connection with the repurchase of 1.8 million shares of its common stock (paying an average price of $90.57 per share). During the three months ended December 31, 2021, the Company paid $269.4 million (including commissions) in connection with the repurchase of 1.7 million shares of its common stock (paying an average price of $159.56 per share). As of December 30, 2022, $947.0 million remained available under the January 26, 2021 stock repurchase program.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE The following table sets forth the computation of basic and diluted earnings per share (in millions, except per share amounts): Three Months Ended December 30, December 31, Net income $ 309.4 $ 399.9 Weighted average shares outstanding – basic 159.8 165.1 Dilutive effect of equity-based awards 0.4 1.3 Weighted average shares outstanding – diluted 160.2 166.4 Net income per share – basic $ 1.94 $ 2.42 Net income per share – diluted $ 1.93 $ 2.40 Anti-dilutive common stock equivalents 1.0 0.2 Basic earnings per share are calculated by dividing net income by the weighted average number of shares of the Company’s common stock outstanding during the period. The calculation of diluted earnings per share includes the dilutive effect of equity-based awards that were outstanding during the three months ended December 30, 2022, and December 31, 2021, using the treasury stock method. Shares issuable upon the vesting of performance stock awards are likewise included in the calculation of diluted earnings per share as of the date the condition(s) have been satisfied, assuming the end of the reporting period was the end of the contingency period. Certain of the Company’s outstanding share-based awards, noted in the table above, were excluded because they were anti-dilutive, but they could become dilutive in the future.
