Revenue from Contract with Customer [Abstract]

REVENUE RECOGNITION

The Company presents net revenue by geographic area, based upon the location of the original equipment manufacturers’ (“OEMs”) headquarters, and by sales channel, as it believes that doing so best depicts how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. Individually insignificant OEMs are presented based upon the location of the Company’s direct customer, which is typically a distributor.

Net revenue by geographic area is as follows (in millions):

The Company’s revenue from external customers is generated principally from the sale of semiconductor products that facilitate various wireless communication applications. Accordingly, the Company considers its product offerings to be similar in nature and therefore not segregated for reporting purposes.

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				Nine Months Ended
	June 28, 2024		June 30, 2023		June 28, 2024		June 30, 2023
Net income	$	120.9	$	195.8	$	535.5	$	738.0

Weighted average shares outstanding – basic	160.4		159.2		160.2		159.4
Dilutive effect of equity-based awards	1.0		0.8		1.2		0.6
Weighted average shares outstanding – diluted	161.4		160.0		161.4		160.0

Net income per share – basic	$	0.75	$	1.23	$	3.34	$	4.63
Net income per share – diluted	$	0.75	$	1.22	$	3.32	$	4.61

Anti-dilutive common stock equivalents	0.3		0.7		—		0.5

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 and nine months ended June 28, 2024, and June 30, 2023, 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.

Description of Business, Basis of Presentation, and Summary of Significant Accounting Policies (Policies)	9 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting, Policy	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 29, 2023, filed with the SEC on November 17, 2023, as amended by Amendment No. 1 to such Annual Report on Form 10-K, filed with the SEC on January 26, 2024 (“2023 10-K”). Certain items in the prior period financial statements have been reclassified to conform to the current period presentation. 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.
Fiscal Period	The Company’s fiscal year ends on the Friday closest to September 30. The fiscal year ending on September 27, 2024 consists of 52 weeks (“fiscal 2024”). The fiscal year ended on September 29, 2023 consisted of 52 weeks (“fiscal 2023”). The three and nine months ended June 28, 2024, and June 30, 2023, each consisted of 13 weeks and 39 weeks, respectively.
Property, Plant, and Equipment, Policy	Property, Plant, and Equipment Property, plant, and equipment are carried at cost less accumulated depreciation, with significant renewals and betterments being capitalized and retired equipment written off in the respective periods. Maintenance and repairs are expensed as incurred. Depreciation is calculated using the straight-line method over the estimated useful lives, which range from five to forty years for buildings and improvements and from five to ten years for machinery and equipment. Leasehold improvements are depreciated over the lesser of the economic life or the life of the associated lease.
Use of Estimates, Policy	During the nine months ended June 28, 2024, the Company changed its accounting estimate for the expected useful lives of certain machinery and equipment. The Company evaluated its current asset base and reassessed the estimated useful lives of certain machinery and equipment in connection with its recent usage of older equipment, including considering the technological and physical obsolescence of such machinery and equipment. Based on its ability to re-use equipment across generations of process technologies and historical usage trends, the Company determined that the expected useful lives for certain machinery and equipment should be increased by up to two years to reflect more closely the estimated economic lives of those assets. This change in estimate was applied prospectively effective during the first quarter of fiscal 2024 and resulted in a decrease in depreciation expense of $18.9 million and $56.6 million for the three and nine months ended June 28, 2024, respectively. This benefit decreased cost of goods sold by $8.9 million and $10.7 million and decreased research and development expenses by $2.4 million and $7.4 million for the three and nine months ended June 28, 2024, respectively, and decreased ending inventory by $38.5 million as of June 28, 2024. As a result of this change in accounting estimate, net income increased by $11.3 million and $18.1 million and diluted earnings per share increased by $0.07 and $0.11 for the three and nine months ended June 28, 2024, respectively.
Recently Issued Accounting Pronouncements, Policy	Recently Issued Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosure” (“ASU 2023-07”). ASU 2023-07 requires disclosure of incremental segment information on an annual and interim basis. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, on a retrospective basis. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2023-07 on its consolidated financial statements and related disclosures. In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”). ASU 2023-09 includes amendments that further enhance income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, on either a prospective or retrospective basis, with early adoption permitted. The Company is currently evaluating the impact of ASU 2023-09 on its consolidated financial statements and related disclosures.

Commitments and Contingencies	Jun. 28, 2024
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 assess whether loss contingencies should be recognized and 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 the accompanying consolidated balance sheets and does not expect that such obligations will have a material adverse impact on its financial statements. Purchase Commitments The Company purchases materials primarily pursuant to individual purchase orders, some of which have underlying master purchase agreements. Some of these purchase commitments are cancellable, and some are non-cancelable, depending on the terms with each individual supplier. In the event of cancellation, the Company may be required to pay costs incurred through the date of cancellation or other fees. When cancellation would result in incurring costs or other fees, the Company has historically sought to negotiate amended terms to the original agreements and orders to limit its exposure. As such, the Company believes that purchase commitments as of any particular date may not be a reliable indicator of future commitments.

Fair Value

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
	June 28, 2024								September 29, 2023
			Fair Value Measurements								Fair Value Measurements
	Total		Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3

Total assets at fair value	$	1,283.9	$	1,264.6	$	19.3	$	—	$	738.5	$	718.5	$	20.0	$	—

(1) Cash equivalents included in Levels 1 and 2 consist of money market funds, municipal bonds, and U.S. Treasury and government 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. During the three and nine months ended June 28, 2024, the Company recorded impairment charges of $0.7 million and $16.8 million, respectively. The impairment charges for the nine months ended June 28, 2024 primarily related to the abandonment of a previously capitalized in-process research and development (“IPR&D”) project. During the three months ended June 30, 2023, there were no indicators of impairment identified. During the nine months ended June 30, 2023, the Company recorded impairment charges of $17.0 million.

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 amount and estimated fair value of debt consists of the following (in millions):


	As of
	June 28, 2024				September 29, 2023
	Carrying Amount		Estimated Fair Value		Carrying Amount		Estimated Fair Value
1.80% Senior Notes due 2026	$	498.4	$	465.1	$	497.7	$	444.5
3.00% Senior Notes due 2031	495.6		424.8		495.2		390.4
Total debt under Senior Notes	$	994.0	$	889.9	$	992.9	$	834.9

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Income Taxes

INCOME TAXES

The provision for income taxes consists of the following components (in millions):


	Three Months Ended						Nine Months Ended
	June 28, 2024			June 30, 2023			June 28, 2024			June 30, 2023
United States income taxes	$	8.6		$	17.5		$	16.0		$	60.0
Foreign income taxes	3.9			8.8			26.5			34.6
Provision for income taxes	$	12.5		$	26.3		$	42.5		$	94.6
Effective tax rate	9.4		%	11.8		%	7.4		%	11.4		%

The difference between the Company’s effective tax rate and the 21.0% United States federal statutory rate for the three and nine months ended June 28, 2024 and June 30, 2023 resulted primarily from foreign earnings taxed at rates lower than the federal statutory rate, a benefit from foreign-derived intangible income deduction (“FDII”), 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 share-based compensation shortfalls.

In August 2022, the U.S. government enacted the Inflation Reduction Act, which imposes a corporate alternative minimum tax (“CAMT”) of 15% on corporations with three-year average annual adjusted financial statement income exceeding $1.0 billion. The Company is subject to the provisions of CAMT in fiscal 2024. CAMT had no impact to the Company’s consolidated financial statements for the three and nine months ended June 28, 2024.

ITEM 5. OTHER INFORMATION.

Director and Officer Trading Arrangements

A significant portion of the compensation of our directors and officers (as defined in Rule 16a-1(f) under the Exchange Act) is in the form of equity awards and, from time to time, directors and officers engage in open-market transactions with respect to the securities acquired pursuant to such equity awards or our other securities, including to satisfy tax withholding obligations when equity awards vest or are exercised, and for diversification or other personal reasons.

Transactions in our securities by directors and officers are required to be made in accordance with our insider trading policy, which requires that the transactions be in accordance with applicable U.S. federal securities laws that prohibit trading while in possession of material nonpublic information. Rule 10b5-1 under the Exchange Act provides an affirmative defense that enables directors and officers to prearrange transactions in our securities in a manner that avoids concerns about initiating transactions while in possession of material nonpublic information.

The following table describes contracts, instructions or written plans for the sale or purchase of our securities adopted by our directors and officers during the quarter covered by this report that are intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) (a “Rule 10b5-1 trading arrangement”):

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business, Basis of Presentation, and Summary of Significant Accounting Policies	DESCRIPTION OF BUSINESS, BASIS OF PRESENTATION, AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 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 29, 2023, filed with the SEC on November 17, 2023, as amended by Amendment No. 1 to such Annual Report on Form 10-K, filed with the SEC on January 26, 2024 (“2023 10-K”). Certain items in the prior period financial statements have been reclassified to conform to the current period presentation. 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. The Company’s fiscal year ends on the Friday closest to September 30. The fiscal year ending on September 27, 2024 consists of 52 weeks (“fiscal 2024”). The fiscal year ended on September 29, 2023 consisted of 52 weeks (“fiscal 2023”). The three and nine months ended June 28, 2024, and June 30, 2023, each consisted of 13 weeks and 39 weeks, respectively. Property, Plant, and Equipment Property, plant, and equipment are carried at cost less accumulated depreciation, with significant renewals and betterments being capitalized and retired equipment written off in the respective periods. Maintenance and repairs are expensed as incurred. Depreciation is calculated using the straight-line method over the estimated useful lives, which range from five to forty years for buildings and improvements and from five to ten years for machinery and equipment. Leasehold improvements are depreciated over the lesser of the economic life or the life of the associated lease. During the nine months ended June 28, 2024, the Company changed its accounting estimate for the expected useful lives of certain machinery and equipment. The Company evaluated its current asset base and reassessed the estimated useful lives of certain machinery and equipment in connection with its recent usage of older equipment, including considering the technological and physical obsolescence of such machinery and equipment. Based on its ability to re-use equipment across generations of process technologies and historical usage trends, the Company determined that the expected useful lives for certain machinery and equipment should be increased by up to two years to reflect more closely the estimated economic lives of those assets. This change in estimate was applied prospectively effective during the first quarter of fiscal 2024 and resulted in a decrease in depreciation expense of $18.9 million and $56.6 million for the three and nine months ended June 28, 2024, respectively. This benefit decreased cost of goods sold by $8.9 million and $10.7 million and decreased research and development expenses by $2.4 million and $7.4 million for the three and nine months ended June 28, 2024, respectively, and decreased ending inventory by $38.5 million as of June 28, 2024. As a result of this change in accounting estimate, net income increased by $11.3 million and $18.1 million and diluted earnings per share increased by $0.07 and $0.11 for the three and nine months ended June 28, 2024, respectively. Recently Issued Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosure” (“ASU 2023-07”). ASU 2023-07 requires disclosure of incremental segment information on an annual and interim basis. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, on a retrospective basis. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2023-07 on its consolidated financial statements and related disclosures. In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”). ASU 2023-09 includes amendments that further enhance income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, on either a prospective or retrospective basis, with early adoption permitted. The Company is currently evaluating the impact of ASU 2023-09 on its consolidated financial statements and related disclosures.

On January 31, 2023, the Board of Directors approved a stock repurchase program (“January 31, 2023 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 through February 1, 2025, on the open market or in privately negotiated transactions, in compliance with applicable securities laws and other legal requirements. The January 31, 2023 stock repurchase program succeeds in its entirety the stock repurchase program approved by the Board of Directors on January 26, 2021 (“January 26, 2021 stock repurchase program”). The timing and amount of any shares of the Company’s common stock that are repurchased under the January 31, 2023 stock repurchase program will be determined by the Company’s management based on its evaluation of market conditions and other factors. The January 31, 2023 stock repurchase program may be suspended or discontinued at any time. The Company currently expects to fund the January 31, 2023 stock repurchase program using the Company’s working capital.

During the three and nine months ended June 28, 2024, the Company paid $77.4 million (including commissions and excise tax, as applicable) in connection with the repurchase of 0.8 million shares of its common stock (paying an average price of $101.33 per share), all of which shares were repurchased pursuant to the January 31, 2023 stock repurchase program. As of June 28, 2024, $1.9 billion remained available under the January 31, 2023 stock repurchase program.

During the three months ended June 30, 2023, the Company did not repurchase any shares of its common stock pursuant to the January 31, 2023 stock repurchase program. During the nine months ended June 30, 2023, the Company paid $175.3 million (including commissions) in connection with the repurchase of 1.9 million shares of its common stock (paying an average price of $90.60 per share), all of which shares were repurchased pursuant to the January 26, 2021 stock repurchase program.
