Lastly, we leverage our customer relationships with cross-selling opportunities across product lines in order to maximize revenue.

We believe that maintaining frequent and interactive contact with our customers is paramount to our continuous efforts to provide world-class sales and service support. By listening and responding to feedback, we are able to mobilize resources to raise our level of customer satisfaction, improve our ability to anticipate future product needs, and enhance our understanding of key market dynamics. We are confident that diligently following this path positions us to participate in numerous opportunities for growth in the future.

Customer Concentration

A small number of OEMs historically has accounted for a significant portion of our net revenue. In each of the fiscal years ended September 27, 2024 (“fiscal 2024”), September 29, 2023 (“fiscal 2023”), and September 30, 2022 (“fiscal 2022”), Apple, through sales to multiple distributors and contract manufacturers for multiple applications including smartphones, tablets, desktop and notebook computers, watches, and other devices, constituted more than ten percent of our net revenue. Further, the Company’s three largest accounts receivable balances comprised 80% and 83% of aggregate gross accounts receivable as of September 27, 2024 and September 29, 2023, respectively. For further information regarding customer concentrations, see Note 14 to Item 8 of this Annual Report on Form 10-K.

Intellectual Property and Proprietary Rights

We own or have a license to use numerous United States and foreign patents and patent applications related to our products and our manufacturing operations and processes. In addition, we own a number of trademarks and service marks applicable to certain of our products and services. We believe that our intellectual property, including patents, patent applications, trade secrets, and trademarks, is of material importance to our business. We rely on patent, copyright, trademark, trade secret, and other intellectual property laws, as well as non-disclosure and confidentiality agreements and other methods, to protect our confidential and proprietary technologies, designs, devices, algorithms, processes, and other intellectual property. Our efforts may not meaningfully protect our intellectual property, or others may independently develop substantially equivalent or superior proprietary technologies, designs, devices, algorithms, processes, or other intellectual property. In addition, the laws of some foreign countries do not protect proprietary rights to the same extent as the laws of the United States, and effective copyright, patent, trademark, and trade secret protection may not be available in those jurisdictions. In addition to protecting our intellectual property, we strive to strengthen our intellectual property portfolio to enhance our ability to obtain cross-licenses of intellectual property from others, to obtain access to intellectual property we do not possess, and to more favorably resolve potential intellectual property claims against us. Due to rapid technological changes in the industry, we believe establishing and maintaining a technological leadership position depends primarily on our ability to develop new, innovative products through the technical competence of our engineering personnel.

Competitive Conditions

The competitive environment in the semiconductor industry is in a constant state of flux, with new products continually emerging and existing products approaching technological obsolescence. We compete on the basis of time-to-market, new product innovation, quality, performance, price, compliance with industry standards, strategic relationships with customers and baseband vendors, personnel resources, and protection of our intellectual property. We participate in highly competitive markets against numerous competitors that may be able to adapt more quickly to new or emerging technologies and changes in customer requirements, or may be able to devote greater resources to the development, promotion, and sale of their products.

Research and Development

Our products and markets demand rapid technological advancements requiring a continuous effort to enhance existing products and develop new products and technologies. Accordingly, we maintain a high level of research and development activity. We invested $631.7 million, $606.8 million, and $617.9 million in research and development during fiscal 2024, fiscal 2023, and fiscal 2022, respectively. The level of research and development expenses were the result of increases in our internal product designs and product development activity for our target markets in each of these fiscal years. Our research and development expenses include new product development and innovations in integrated circuit design, investment in advanced semiconductor manufacturing processes, development of new packaging and test capabilities, and research on next-generation technologies and product opportunities. We maintain close collaborative relationships with many of our customers to help identify market demands and target our development efforts to meet those demands.

Raw Materials

Raw materials for our products and manufacturing processes are generally available from several sources. It is our intent not to depend on a sole source of supply unless market or other conditions dictate otherwise. However, there are limited situations where we procure certain components and services for our products from single or limited sources, and we are currently dependent on a limited number of sole-source suppliers. We purchase materials and services primarily pursuant to individual purchase orders. However, we have entered into certain supply agreements for the purchase of raw materials or other manufacturing-related services that specify minimum prices and purchase quantity based on our anticipated future requirements. Certain of our suppliers consign raw materials to us at our manufacturing facilities to which we take title as needed in our manufacturing process. We have taken strategic action with suppliers located around the world to secure sourcing of the raw materials and components necessary for our manufacturing.

Backlog and Inventory

Our sales are primarily from the sale of semiconductor products under individual customer purchase orders, some of which have underlying master sales agreements that specify terms governing the product sales. In the absence of a sales agreement, the Company’s standard terms and conditions apply. Due to industry practice, which allows customers to cancel orders with limited advance notice to us prior to shipment, and with little or no penalty, we believe that backlog as of any particular date may not be a reliable indicator of our future revenue levels. The cancellation or deferral of product orders, the return of previously sold products, or overproduction due to a change in anticipated order volume could result in a reduction in revenue and us holding

excess or obsolete inventory, which could result in inventory write-downs and, in turn, could have a material adverse effect on our financial condition.

Government Regulations

We are subject to international, federal, state, and local legislation, regulations, and other requirements relating to the discharge of substances into the environment; the treatment, transport, and disposal of hazardous wastes; recycling and product packaging; worker health and safety; and other activities affecting the environment, our workforce, and the management of our manufacturing operations. In addition, most of our customers have mandated that our operations and our products comply with various sustainability initiatives and workers’ rights initiatives initiated by such customers, industry groups in which such customers participate, or the jurisdictions in which such customers operate. We believe that our operations and facilities comply in all material respects with applicable environmental laws and worker health and safety laws. Our efforts to comply with environmental laws and worker health and safety laws could have material impacts on our capital expenditures, competitive position, or financial condition, though the magnitude and duration of such impacts are uncertain and difficult to quantify.

We are also subject to import/export controls, tariffs, and other trade-related regulations and restrictions in the countries in which we have operations or otherwise do business. These controls, tariffs, regulations, and restrictions (including those discussed below in Item 1A, Risk Factors) have had, and we believe may continue to have, a material impact on our business, including our ability to sell products and to manufacture or source components.

Government regulations are subject to change in the future, and accordingly we are unable to assess the possible effect of compliance with future requirements or whether our compliance with such regulations will materially impact our business, results of operations, or financial condition.

Seasonality

Sales of our products are subject to seasonal fluctuation and periods of increased demand in end-user consumer applications, such as smartphones and tablet computing devices. The highest demand for our products generally occurs in our first fiscal quarter ending in December and the fourth fiscal quarter ending in September. The lowest demand for our products generally occurs in our second fiscal quarter ending in March and the third fiscal quarter ending in June.

Employees

Our workforce consists of approximately 10,100 employees located around the world, more than 99% of whom are full-time employees. As of September 27, 2024:

• Our workforce was distributed geographically approximately as follows: 54% in Mexico, 25% in the United States, 19% in Asia, 1% in Canada, and less than 1% in Europe.

• Our workforce was distributed by function approximately as follows: 41% in individual contributor manufacturing roles, 35% in engineering or technician roles, 11% in managerial roles, and 13% in professional or other administrative roles.

• Approximately 3,400 of our employees in Mexico, 570 of our employees in Singapore, and 440 of our employees in Japan were covered by collective bargaining and other union agreements.

We focus on attracting and retaining employees by providing compensation and benefits packages that are competitive within the applicable market for each position. Nearly all full-time employees across the globe are eligible to participate in one of the Company’s incentive plans, under which payments are tied to pre-established performance goals, as well as to purchase shares of the Company’s common stock at a discount from its market price pursuant to the Company’s employee stock purchase plans. In addition, we believe that developing our employees’ skill sets and decision-making abilities—through challenging project assignments, formal training, mentorship, and recognition—is key not only to our employees’ job satisfaction and our retention efforts, but also to maintaining a strong leadership pipeline.

You should carefully consider the risks described below, some of which have manifested and any of which may occur in the future, in addition to the other information contained in this report before making an investment decision with respect to any of our securities. Our business, results of operations, and financial condition could be materially and adversely impacted by any of these risks, which could, in turn, adversely affect our stock price. Additional risks not currently known to us or other factors not perceived by us as material risks could also present significant risks to our business.

• difficulty in collecting, or failure to collect, accounts receivable, as well as longer collection periods,

• changes in, or non-compliance with, legal or regulatory import/export requirements, including restrictions on selling to certain customers or into certain jurisdictions,

• natural disasters and severe weather events, including, but not limited to, earthquakes, wildfires, droughts, hurricanes, tsunamis, floods, rising sea levels, as well as other impacts of climate change,

• acts of terrorism, widespread illness, the effects of global health crises on business conditions in our industry or in the jurisdictions in which we do business, or other deterioration of public health conditions, and war,

• misappropriation or other unauthorized transfers of our information and breaches of our information systems, as well as the potential lack of adequate remedies or enforcement mechanisms in certain jurisdictions,

• difficulty in engaging distribution partners or obtaining sales or other business support in certain jurisdictions,

• cultural differences in the conduct of business,

• direct or indirect government actions, subsidies, or policies aimed at supporting local industry,

• the laws and policies of the United States and other countries affecting trade, foreign investment and loans, foreign travel, and import or export licensing requirements, including, but not limited to, prohibitions on certain trade and other activities in China, Russia, Belarus, and portions of Ukraine,

• withdrawal from, or renegotiation of, existing trade agreements by the United States (or other jurisdictions) potentially affecting Mexico, China, and other countries in which we do business,

• changes in current or future tax law or regulations or new interpretations thereof, by federal or state agencies or foreign governments,

• changes in the effective tax rate as a result of our overall profitability and mix of earnings in countries with differing statutory tax rates,

• results of audits and examination of previously filed tax returns, and

• limitations on our ability under local laws to protect or enforce our intellectual property rights in a particular foreign jurisdiction.

Additionally, we are subject to risks in certain global markets in which wireless operators provide subsidies on handset sales to their customers. Increases in cellular handset prices that negatively impact handset sales can result from changes in regulatory policies or other factors, which could impact the demand for our products.

Some of the countries in which we operate and seek to expand are in emerging markets where legal systems may be less developed or familiar to us, potentially impacting our ability to obtain appropriate recourse in the event of a dispute. Other jurisdictions in which we conduct business have established, or may establish, legal and regulatory regimes that differ materially from United States laws and regulations. It is costly, time-consuming, and requires significant resources to comply with the numerous, and sometimes conflicting, legal regimes in the jurisdictions in which we conduct business on matters as diverse as anti-corruption, anti-bribery, import/export controls, content requirements, trade restrictions, tariffs, taxation, sanctions, immigration, intellectual property, sustainability, internal and disclosure control obligations, securities regulation, competition, data privacy and protection, employment, and labor relations. Violations of one or more of these legal regimes’ laws and regulations in the conduct of our business could result in significant fines, penalties, or monetary damages, criminal sanctions against us or our officers, prohibitions on doing business, unfavorable publicity and other reputational damage, restrictions on our ability to process information, and allegations by our counterparties that we have not performed our contractual obligations.

Changes in tax laws and regulations could have an adverse impact on our operating results.

We are subject to taxation in many different countries and localities worldwide. To the extent the tax laws and regulations in these various countries and localities change, our tax liability could increase.

Beginning in fiscal 2023, for U.S. income tax purposes we were required to capitalize our research and development expenses and amortize them over five or fifteen years, rather than deduct them in the year incurred, which has increased, and which we expect will continue

Cybersecurity Risk Management and Strategy

We have developed and implemented processes for identifying, assessing, and managing cybersecurity risks as part of our overall enterprise risk management program. These processes are designed to protect our information technology and operational systems against cybersecurity threats. In connection with the operation of our program, we take into consideration guidance from various recognized cybersecurity industry frameworks and standards such as the National Institute of Standards and Technology Cybersecurity Framework (“NIST CSF”) and the International Organization for Standardization (“ISO”) 27001 standards. This does not mean that we adhere to any particular frameworks or meet any particular standards, but rather that we use industry frameworks and standards as a guide to help us identify, assess, and manage cybersecurity risks relevant to our business. Information about cybersecurity risk is collected as part of our overall enterprise risk management program, including as part of the annual enterprise risk assessment survey conducted by our internal audit team, the results of which are summarized and provided to our Audit Committee.

We devote significant resources and efforts to protecting the security of our information technology and operational systems, including utilizing threat monitoring and commissioning assessments by third parties, taking guidance from ISO information security standards, and conducting proactive risk and compliance reviews against regulatory, industry, and evolving data privacy requirements. We provide training to our employees on our acceptable use policy, our data protection methods, and social engineering tactics used by threat actors, including through simulated phishing attacks. We maintain a cross-functional cybersecurity incident management procedure with defined roles, responsibilities, and reporting protocols that is designed to timely respond to, investigate, mitigate, remediate, and if appropriate, disclose, a cybersecurity incident. Furthermore, we practice our response to potential cybersecurity incidents through tabletop exercises.

As part of our selection process for certain third-party service providers, we evaluate components of their cybersecurity risk management programs using various factors. We engage third-party providers to provide ongoing threat monitoring, mitigation strategies, updates on emerging trends, security assessments, and penetration testing. We also receive updates from law enforcement and industry groups on emerging cybersecurity trends and the latest threats, and we have standing engagements with incident response experts.

As of the date of this Annual Report on Form 10-K, we have not identified any risks from cybersecurity threats that have materially affected or are reasonably likely to materially affect our company, including our business strategy, results of operations, or financial condition. For additional information regarding risks we face, please refer to “We may not be able to prevent, or timely detect, information technology security breaches” in Item 1A, “Risk Factors,” in this Annual Report on Form 10-K.

Cybersecurity Governance

Our Board of Directors (“Board”) is responsible for our risk oversight, with the Audit Committee specifically overseeing management’s cybersecurity risk management program. In this role, the Audit Committee receives quarterly updates from members of management, including the vice president, information technology and CIO, who oversees our information technology function (“CIO”) and another vice president who supports the CIO in implementing, monitoring and updating the cybersecurity risk management program, as well as addressing existing and emerging cybersecurity threats and managing cybersecurity incidents (“Head of Information Security”). The Board receives regular reports from the Audit Committee, as well as an annual cybersecurity report from management, including the CIO, highlighting key activities of the Company’s cybersecurity team, including internal initiatives and updates and external engagements with third party cybersecurity firms, recent incidents throughout the industry and the emerging threat landscape.

Our CIO has more than 25 years of experience in information technology and reports to our Chief Financial Officer. Our Head of Information Security, who reports to the CIO, has over 20 years of experience managing global information technology and cybersecurity operations and holds multiple industry-recognized certifications such as Certified Information Systems Security Professional and Certificate of Cloud Security Knowledge.

We maintain our primary executive offices in Irvine, California. For information regarding property, plant, and equipment by geographic region for each of the last two fiscal years, see Note 14 to Item 8 of this Annual Report on Form 10-K. The following table sets forth our principal facilities:

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes that appear elsewhere in this Annual Report on Form 10-K. In addition to historical information, the following discussion contains forward-looking statements that are subject to risks and uncertainties. Actual results may differ substantially and adversely from those referred to herein due to a number of factors, including, but not limited to, those described below and in Item 1A “Risk Factors” and elsewhere in this Annual Report on Form 10-K.

OVERVIEW

We, together with our consolidated subsidiaries, are a leading developer, manufacturer and provider of analog and mixed-signal semiconductor products and solutions for numerous applications, including aerospace, automotive, broadband, cellular infrastructure, connected home, defense, entertainment and gaming, industrial, medical, smartphone, tablet, and wearables.

RESULTS OF OPERATIONS

Fiscal Years Ended September 27, 2024, September 29, 2023, and September 30, 2022

The following table sets forth the results of our operations expressed as a percentage of net revenue. See Part II, Item 7 of our 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 (the “2023 10-K”), for Management’s Discussion and Analysis of Financial Condition and Results of Operations for the fiscal year ended September 30, 2022.

General

During the fiscal year ended September 27, 2024, the following key factors contributed to our overall results of operations, financial position, and cash flows:

• Net revenue decreased 12.5% to $4,178.0 million in fiscal 2024, as compared to $4,772.4 million in fiscal 2023, driven primarily by a decrease in demand for our mobile, analog, and mixed-signal products.

• Our ending cash, cash equivalents, and marketable securities balance increased 113.1% to $1,574.1 million in fiscal 2024, as compared to $738.5 million in fiscal 2023. The increase in cash, cash equivalents, and marketable securities during fiscal 2024, was primarily due to cash generated from operations of $1,824.7 million, partially offset by

dividend payments of $439.1 million, repayments of debt of $300.0 million, capital expenditures of $157.0 million, and share repurchases of $77.3 million.

Net Revenue

We market and sell our products indirectly through electronic components distributors and directly to OEMs of communications and electronics products, third-party original design manufacturers and contract manufacturers. We generally experience seasonal peaks during our fourth and first fiscal quarters (which correspond to the second half of the calendar year), primarily as a result of increased worldwide production of consumer electronics in anticipation of holiday sales, whereas our second and third fiscal quarters are typically lower and in line with seasonal industry trends.

The decrease in net revenue in fiscal 2024, as compared to fiscal 2023, was driven primarily by a decrease in demand for our mobile, analog, and mixed-signal products.

For information regarding net revenue by geographic region and customer concentration, see Note 14 to Item 8 of this Annual Report on Form 10-K.

Gross Profit

Gross profit represents net revenue less cost of goods sold. Our cost of goods sold consists primarily of purchased materials, labor, and overhead (including depreciation, share-based compensation expense, and amortization of acquisition intangibles) associated with product manufacturing. Erosion of average selling prices of established products is typical of the semiconductor industry. Consistent with trends in the industry, we anticipate that average selling prices for our established products will continue to decline over time. As part of our normal course of business, we intend to improve gross profit with efforts to increase unit volumes, improve manufacturing efficiencies, lower manufacturing costs of existing products, and by introducing new and higher value-added products.

The decrease in gross profit in fiscal 2024, as compared to fiscal 2023, was primarily the result of an unfavorable product mix, lower unit volumes, and lower average selling prices.

Research and Development

Research and development expenses consist primarily of direct personnel costs including share-based compensation expense, costs for pre-production evaluation units and testing of new devices, non-production masks, engineering prototypes, and design tool costs.

The increase in research and development expenses in fiscal 2024, as compared to fiscal 2023, was primarily related to increases in certain headcount-related expenses and costs for engineering prototypes as a result of our increased investment in developing new technologies and products, partially offset by a decrease in share-based compensation expense and a decrease in depreciation expense as a result of extending the useful lives of certain machinery and equipment. For information regarding this change in accounting estimate, see Note 2 to Item 8 of this Annual Report on Form 10-K.

Selling, General, and Administrative

Selling, general, and administrative expenses include legal and related costs, accounting, treasury, human resources, information systems, customer service, bad debt expense, sales commissions, share-based compensation expense, advertising, marketing, costs associated with business combinations completed or contemplated during the period, and other costs.

The decrease in selling, general, and administrative expenses in fiscal 2024, as compared to fiscal 2023, was primarily related to a gain on the sale of property, plant, and equipment, a decrease in professional services costs, and a decrease in share-based compensation expense.

Amortization of Intangibles

The decrease in amortization expense in fiscal 2024, as compared to fiscal 2023, was primarily due to certain intangible assets that were acquired in prior fiscal years reaching the end of their useful lives.

Impairment, Restructuring, and Other Charges

Impairment, restructuring, and other charges in fiscal 2024 were primarily due to the abandonment or delay of previously capitalized in-process research and development (“IPR&D”) projects of $147.9 million and employee severance costs.

Impairment, restructuring, and other charges in fiscal 2023 were primarily due to employee severance costs and impairment charges on divested assets.

Interest Expense

The decrease in interest expense in fiscal 2024, as compared to fiscal 2023, was due to certain debt repayments that reduced the amount of outstanding indebtedness.

Other Income (Expense), Net

The increase in other income, net in fiscal 2024, as compared to fiscal 2023, was primarily due to an increase in interest income generated from cash, cash equivalents, and marketable securities.

Provision for Income Taxes

We recorded a provision for income taxes of $40.4 million (which consisted of benefits of $41.5 million and $0.3 million related to United States federal and state income taxes, respectively, and a provision of $82.2 million related to foreign income taxes) and $96.0 million (which consisted of $62.0 million and $34.0 million related to United States and foreign income taxes, respectively) in fiscal 2024 and fiscal 2023, respectively.

The decrease in income tax expense in fiscal 2024, as compared to fiscal 2023, was primarily due to lower income from operations and a higher proportion of foreign income compared to domestic, partially offset by a decrease in the benefit from foreign-derived intangible income (“FDII”), an increase in tax expense related to a change in the reserve for uncertain tax positions, and an increase in the tax on global intangible low-taxed income (“GILTI”), net of foreign tax credits.

Future changes in tax laws could arise related to the BEPS Project of the OECD, including Pillar One and Pillar Two; the European Commission’s “state aid” investigations; enactment of a global corporate minimum tax; and other developments that could have an adverse effect on the taxation of our business, including reducing the availability of tax credits and payment of higher income taxes. Many countries have implemented laws based on Pillar Two which will be effective for us in fiscal year 2025. We continue to evaluate the impact of proposed and enacted legislative changes to our effective tax rate as new guidance becomes available.

See Note 8 to Item 8 of this Annual Report on Form 10-K for additional information regarding income taxes.

LIQUIDITY AND CAPITAL RESOURCES

Cash provided by operating activities:

Cash provided by operating activities consists of net income for the period adjusted for certain non-cash items and changes in certain operating assets and liabilities. The $31.7 million decrease in cash provided by operating activities for fiscal 2024, as compared to fiscal 2023, was primarily related to lower net income, partially offset by favorable changes in working capital of $402.9 million, due primarily to a decrease in inventory and accounts receivable.

Cash used in investing activities:

Cash used in investing activities consists primarily of capital expenditures, cash paid to acquire intangible assets, and cash paid to purchase marketable securities, offset by cash received related to the sale or maturity of marketable securities. The

$131.5 million increase in cash used in investing activities for fiscal 2024, as compared to fiscal 2023, was primarily related to a decrease of $207.5 million in sales of marketable securities, partially offset by a decrease of $17.9 million in purchases of marketable securities and a decrease of $53.3 million in cash used for capital expenditures.

Cash used in financing activities:

Cash used in financing activities consists primarily of proceeds and payments related to our long-term borrowings and cash transactions related to equity. The $660.2 million decrease in cash used in financing activities for fiscal 2024, as compared to fiscal 2023, was primarily related to a decrease of $600.0 million for the repayment of debt and a decrease of $98.0 million in stock repurchase activity, partially offset by an increase of $33.9 million in dividend payments.

Liquidity:

Cash, cash equivalents, and marketable securities totaled $1,574.1 million as of September 27, 2024, representing an increase of $835.6 million from September 29, 2023.

We have outstanding $500.0 million of Notes Due 2026 and $500.0 million of Notes Due 2031. During fiscal 2024, 2023, and 2022, we repaid $300.0 million, $900.0 million, and $50.0 million of outstanding borrowings, respectively. We have a Revolving Credit Agreement (the “Revolving Credit Agreement”) under which we may borrow up to $750.0 million for general corporate purposes and working capital needs of the Company and its subsidiaries. As of September 27, 2024, there were no borrowings outstanding under the revolving credit facility (the “Revolver”). The Revolving Credit Agreement expires July 26, 2026.

For a description of contractual obligations, such as taxes, leases, purchase commitments, and debt, see Note 8, Note 10, Note 11, and Note 16 to Item 8 of this Annual Report on Form 10-K, respectively.

Based on our historical results of operations, we expect that our cash, cash equivalents, and marketable securities on hand, the cash we expect to generate from operations, and funds from our Revolver, will be sufficient to fund our short-term and long-term liquidity requirements primarily arising from: research and development, capital expenditures, potential acquisitions, working capital, quarterly cash dividend payments (if such dividends are declared by the Board of Directors), outstanding commitments, and other liquidity requirements associated with existing operations. However, we cannot be certain that our cash on hand, cash generated from operations, and funds from our Revolver will be available in the future to fund all of our capital and operating requirements. In addition, any future strategic investments and significant acquisitions may require additional cash and capital resources. If we are unable to obtain sufficient cash or capital to meet our needs on a timely basis and on favorable terms, our business and operations could be materially and adversely affected.

Our invested cash balances primarily consist of highly liquid marketable securities that are available to meet near-term cash requirements including: money market funds, U.S. Treasury and government securities, corporate bonds and notes, and municipal bonds.

CRITICAL ACCOUNTING ESTIMATES

The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The preparation of these financial statements requires us to make estimates and judgments in applying our most critical accounting policies that can have a significant impact on the results we report in our financial statements. The SEC has defined critical accounting estimates as those that are both most important to the portrayal of our financial condition and results and which require our most difficult, complex, or subjective judgments or estimates. Based on this definition, our most critical accounting estimates include revenue recognition, which impacts the recording of net revenue; inventory valuation, which impacts the cost of goods sold and gross margin; and income taxes, which impacts the income tax provision. These policies and significant judgments involved are discussed further below. We have other significant accounting policies that do not generally require subjective estimates or judgments or would not have a material impact on our results of operations. Our significant accounting policies are described in Note 2 to Item 8 of this Annual Report on Form 10-K.

Revenue Recognition. We recognize revenue in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) 606 Revenue from Contracts with Customers net of estimated reserves*.* Our revenue reserves contain uncertainties because they require management to make assumptions and to apply judgment to estimate the value of future credits to customers for product returns, price protection, price adjustments, and stock rotation for products sold to certain electronic component distributors. We base these estimates on the expected value method considering all reasonably available information, including our historical experience and current expectations, and are reflected in the

transaction price when sales are recorded. Changes in actual demand or market conditions could adversely or beneficially impact our reserve calculations.

Inventory Valuation*.* We value our inventory at the lower of cost or net realizable value. Reserves for excess and obsolete inventory are established on a quarterly basis and are based on a detailed analysis of aged material, salability of our inventory, market conditions, and product life cycles. Once reserves are established, write-downs of inventory are considered permanent adjustments to the cost basis of inventory. Our reserves contain uncertainties because the calculation requires management to make assumptions and to apply judgment regarding historical experience, market conditions, and technological obsolescence. Changes in actual demand or market conditions could adversely impact our reserve calculations.

Income Taxes. The application of tax laws and regulations to calculate our tax liabilities is subject to legal and factual interpretation, judgment, and uncertainty in a multitude of jurisdictions. Tax laws and regulations themselves are subject to change as a result of changes in fiscal policy, changes in legislation, the evolution of regulations, and court rulings. We recognize potential liabilities for anticipated tax audit issues in the United States and other tax jurisdictions based on our estimate of whether, and the extent to which, additional taxes and interest will be due. We record an amount as an estimate of probable additional income tax liability at the largest amount that we feel is more likely than not, based upon the technical merits of the position, to be sustained upon audit by the relevant tax authority.

We are subject to overall financial market risks, such as changes in market liquidity, credit quality, investment risk, interest rate risk, and foreign exchange rate risk as described below.

Investment and Interest Rate Risk

Our exposure to interest rate and general market risks relates to our investment portfolio. Our investment portfolio consists of cash and cash equivalents (money market funds, corporate bonds and notes, and U.S. Treasury and government securities purchased with less than ninety days until maturity) that total approximately $1,368.6 million, and marketable securities (U.S. Treasury and government securities, corporate bonds and notes, and municipal bonds) that total approximately $194.1 million and $11.4 million within short-term and long-term marketable securities, respectively, as of September 27, 2024.

The main objectives of our investment activities are liquidity and preservation of capital. Our cash equivalent investments have short-term maturity periods that dampen the impact of market or interest rate risk. Our marketable securities have short-term maturity periods less than one year. Credit risk associated with our investments is not material because our investments are diversified across several types of securities with high credit ratings, which reduces the amount of credit exposure to any one investment.

Based on our results of operations for the fiscal year ended September 27, 2024, a hypothetical reduction in the interest rates on our cash, cash equivalents, and other investments to zero would result in an immaterial reduction of interest income with a de minimis impact on income before taxes.

We do not believe that investment or interest rate risks currently pose material exposures to our business or results of operations.

Foreign Exchange Rate Risk

Substantially all sales to customers and arrangements with third-party manufacturers provide for pricing and payment in United States dollars, thereby reducing the impact of foreign exchange rate fluctuations on our results. A percentage of our international operational expenses are denominated in foreign currencies, and exchange rate volatility could positively or negatively impact those operating costs. For the fiscal years ended September 27, 2024, September 29, 2023, and September 30, 2022, we had foreign exchange losses of $5.2 million, foreign exchange gains of $1.7 million, and foreign exchange losses of $1.4 million, respectively. Increases in the value of the United States dollar relative to other currencies could make our products more expensive, which could negatively impact our ability to compete. Conversely, decreases in the value of the United States dollar relative to other currencies could result in our suppliers raising their prices to continue doing business with us. Given the relatively small number of customers and arrangements with third-party manufacturers denominated in foreign currencies, we do not believe that foreign exchange volatility has a material impact on our current business or results of operations. However, fluctuations in currency exchange rates could have a greater effect on our business or results of operations in the future to the extent our expenses increasingly become denominated in foreign currencies.

We may enter into foreign currency forward and options contracts with financial institutions to protect against foreign exchange risks associated with certain existing assets and liabilities, certain firmly committed transactions, forecasted future cash flows, and net investments in foreign subsidiaries. However, we may choose not to hedge certain foreign exchange exposures for a variety of reasons, including, but not limited to, accounting considerations and the prohibitive economic cost of hedging particular exposures. As of September 27, 2024, we had not entered into any outstanding foreign currency forward or options contracts with financial institutions.

The following consolidated financial statements of the Company are included herewith:

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors

Skyworks Solutions, Inc.:

Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting

We have audited the accompanying consolidated balance sheets of Skyworks Solutions, Inc. and subsidiaries (the Company) as of September 27, 2024 and September 29, 2023, the related consolidated statements of operations, comprehensive income, cash flows, and stockholders’ equity for each of the years in the three-year period ended September 27, 2024, and the related notes (collectively, the consolidated financial statements). We also have audited the Company’s internal control over financial reporting as of September 27, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of September 27, 2024 and September 29, 2023, and the results of its operations and its cash flows for each of the years in the three-year period ended September 27, 2024, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of September 27, 2024 based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable

assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of September 27, 2024. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well-designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on management’s evaluation of our disclosure controls and procedures as of September 27, 2024, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Management’s Annual Report on Internal Control Over Financial Reporting

The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. Internal control over financial reporting is defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, the Company’s principal executive and principal

financial officers and effected by the Company’s Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

• Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;

• Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and

• Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The Company’s management assessed the effectiveness of the Company’s internal control over financial reporting as of September 27, 2024. In making this assessment, the Company’s management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) 2013 Internal Control-Integrated Framework.

Based on their assessment, management concluded that, as of September 27, 2024, the Company’s internal control over financial reporting is effective based on those criteria.

The Company’s independent registered public accounting firm has issued an audit report on the effectiveness of the Company’s internal control over financial reporting as stated within their report which appears herein.

Changes in Internal Control Over Financial Reporting

During the third quarter of fiscal 2024, we completed the implementation of our new enterprise resource planning (“ERP”) system and have modified certain existing internal control processes and procedures related to the new system. These changes did not materially affect our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the fourth quarter of fiscal 2024. As we add new functionality under this ERP system, we will continue to assess the impact on our internal control over financial reporting.

Director and Officer Trading Arrangements

None of our directors or officers adopted or terminated a Rule 10b5-1 trading arrangement (as defined in Item 408(a)(i) of Regulation S-K) or adopted or terminated a non-Rule 10b5-1 trading arrangement (as defined in Item 408(c) of Regulation S-K) during the fourth quarter of fiscal 2024.

Principal Accounting Officer Transition

On November 11, 2024, Philip Carter notified the Company of his intention to resign from his position as Vice President, Corporate Controller and principal accounting officer (“PAO”) of the Company to pursue another opportunity. Mr. Carter’s departure is not due to any disagreement with the Company on any matter relating to the Company’s financial statements, internal control over financial reporting, operations, policies or practices. Mr. Carter will continue to serve as PAO of the Company through November 15, 2024. Effective upon Mr. Carter’s resignation, Kris Sennesael, age 55, Senior Vice President and Chief Financial Officer of the Company, a role he has held since he joined the Company in August 2016, will assume the role of PAO of the Company.

None.
