MICROCHIP TECHNOLOGY INCORPORATED AND SUBSIDIARIES

Notes to Condensed Consolidated Financial Statements

Note 1. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include the accounts of Microchip Technology Incorporated and its majority-owned and controlled subsidiaries (the Company).  All significant intercompany accounts and transactions have been eliminated in consolidation. All dollar amounts in the financial statements and tables in these notes, except per share amounts, are stated in millions of U.S. dollars unless otherwise noted.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. GAAP, pursuant to the rules and regulations of the SEC.  The information furnished herein reflects all adjustments which are, in the opinion of management, of a normal recurring nature and necessary for a fair statement of the results for the interim periods reported. Certain information and footnote disclosures normally included in audited consolidated financial statements have been condensed or omitted pursuant to such SEC rules and regulations.  It is suggested that these condensed consolidated financial statements be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended March 31, 2023.  The results of operations for the three and nine months ended December 31, 2023 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2024 or for any other period.

Note 2. Recently Issued Accounting Pronouncements

Recently Issued Accounting Pronouncements Not Yet Adopted

In November 2023, the FASB issued ASU 2023-07-Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires public entities to disclose significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss, and an amount and description of the composition of other segment items to reconcile to segment profit or loss. The amendments in this update also expand the interim segment disclosure requirements. ASU 2023-07 is effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted with retrospective application required for all prior periods presented in the financial statements. The Company is currently evaluating the applicable disclosures.

In December 2023, the FASB issued ASU 2023-09-Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which modifies the rules on income tax disclosures to enhance the transparency and decision-usefulness of income tax disclosures, particularly in the rate reconciliation table and disclosures about income taxes paid. The amendments are intended to address investors’ requests for income tax disclosures that provide more information to help them better understand an entity’s exposure to potential changes in tax laws and the ensuing risks and opportunities and to assess income tax information that affects cash flow forecasts and capital allocation decisions. The guidance also eliminates certain existing disclosure requirements related to uncertain tax positions and unrecognized deferred tax liabilities. ASU 2023-09 is effective for public business entities for annual periods beginning after December 15, 2024 with early adoption permitted. All entities should apply the guidance prospectively but have the option to apply it retrospectively. The Company is continuing to assess the timing of adoption and the potential impacts of ASC 2023-09.

Note 3. Segment Information

The Company's reportable segments are semiconductor products and technology licensing.  The Company does not allocate operating expenses, interest income, interest expense, other income or expense, or provision for or benefit from income taxes to these segments for internal reporting purposes, as the Company does not believe that allocating these expenses is beneficial in evaluating segment performance.  Additionally, the Company does not allocate assets to segments for internal reporting purposes as it does not manage its segments by such metrics.

Note 4. Net Sales

The following table represents the Company's net sales by product line (in millions):

	Three Months Ended December 31,				Nine Months Ended December 31,
	2023		2022		2023		2022
Mixed-signal Microcontrollers	$	995.2	$	1,221.3	$	3,577.0	$	3,463.8

Total net sales	$	1,765.7	$	2,169.2	$	6,308.6	$	6,206.0

The product lines listed above are included entirely in the Company's semiconductor product segment with the exception of the other product line, which includes products from both the semiconductor product and technology licensing segments.

The following table represents the Company's net sales by customer type (in millions):

	Three Months Ended December 31,				Nine Months Ended December 31,
	2023		2022		2023		2022
Distributors	$	767.6	$	1,032.3	$	3,001.6	$	2,903.7
Direct customers	973.9		1,092.5		3,222.4		3,175.0
Licensees	24.2		44.4		84.6		127.3
Total net sales	$	1,765.7	$	2,169.2	$	6,308.6	$	6,206.0

Distributors are customers that buy products with the intention of reselling them. Distributors generally have a distributor agreement with the Company to govern the terms of the relationship. Direct customers are non-distributor customers, which generally do not have a master sales agreement with the Company. The Company's direct customers primarily consist of OEMs and, to a lesser extent, contract manufacturers. Licensees are customers of the Company's technology licensing segment, which include purchasers of intellectual property and customers that have licensing agreements to use the Company's SuperFlash® embedded flash technology. All of the customer types listed in the table above are included in the Company's semiconductor product segment with the exception of licensees, which is included in the technology licensing segment.

The Company collects amounts in advance for certain of its contracts with customers. These amounts are deferred until control of the product or service is transferred to the customer at which time it is recognized as revenue. As of December 31, 2023, the Company had approximately $907.2 million of deferred revenue, of which $203.2 million is included within accrued liabilities and the remaining $704.0 million is included within other long-term liabilities on the Company's condensed consolidated balance sheet. As of March 31, 2023, the Company had approximately $757.7 million of deferred revenue in the semiconductor product segment, of which $121.4 million is included within accrued liabilities and the remaining $636.3 million is included within other long-term liabilities on the Company's condensed consolidated balance sheets. Deferred revenue represents amounts that have been invoiced in advance which are expected to be recognized as revenue in future periods. Approximately $82.5 million of deferred revenue recorded on the Company's consolidated balance sheets as of March 31, 2023, was recognized as revenue during the nine months ended December 31, 2023. This amount was immaterial for the nine months ended December 31, 2022.

11

Of the $907.2 million of deferred revenue as of December 31, 2023, $868.5 million is cash collected from customers under LTSAs, of which $168.6 million is included within accrued liabilities and $699.9 million is included within other long-term liabilities. Under these LTSAs, the Company receives an upfront deposit from the customer in exchange for assured supply over the contract period, which typically ranges from three to five years. If the customer does not meet the minimum purchase commitments defined in the contract, the Company may retain all, or portions of, the deposit as revenue. If the Company fails to assure supply as defined in the contract, the deposit, or portions of it, will be returned to the customer. The remaining performance obligations for the LTSAs were approximately $3.92 billion as of December 31, 2023, of which approximately 24% is expected to be recognized as net sales during the next 12 months. The amount and timing of such net sales is uncertain because it depends on the satisfaction of commitments made in the LTSAs, which may be affected by the timing and amount of orders placed by customers, contract modifications, variable consideration, sales channels, and manufacturing and supply chain conditions. Accordingly, the amount may not be indicative of net sales in future periods. The remaining $38.7 million of deferred revenue as of December 31, 2023 is related to other cash payments received from customers in advance of the Company’s performance obligations being satisfied. Most of the $38.7 million will be recognized as net sales within the next 12 months. The amount of firmly committed orders with performance obligations in excess of 12 months at the time of order is immaterial.

Note 5. Net Income Per Common Share

The following table sets forth the computation of basic and diluted net income per common share (in millions, except per share amounts):

	Three Months Ended December 31,				Nine Months Ended December 31,
	2023		2022		2023		2022
Net income	$	419.2	$	580.3	$	1,752.2	$	1,633.7
Basic weighted average common shares outstanding	540.8		549.2		543.0		551.5
Dilutive effect of stock options and RSUs	4.9		4.8		5.0		5.1
Dilutive effect of 2015 Senior Convertible Debt	0.2		0.4		0.2		0.7
Dilutive effect of 2017 Senior Convertible Debt	0.6		0.9		0.8		1.0
Dilutive effect of 2017 Junior Convertible Debt	—		0.1		—		0.1
Diluted weighted average common shares outstanding	546.5		555.4		549.0		558.4
Basic net income per common share	$	0.78	$	1.06	$	3.23	$	2.96
Diluted net income per common share	$	0.77	$	1.04	$	3.19	$	2.93

The Company computed basic net income per common share based on the weighted average number of common shares outstanding during the period. The Company computed diluted net income per common share based on the weighted average number of common shares outstanding plus potentially dilutive common shares outstanding during the period.

Potentially dilutive common shares from employee equity incentive plans are determined by applying the treasury stock method to the assumed exercise of outstanding stock options and the assumed vesting of outstanding RSUs. Prior to conversion of its Convertible Debt, the Company will include, in the diluted net income per common share calculation, the effect of the additional shares that may be issued when the Company's common stock price exceeds the conversion price using the if-converted method. The Company's Convertible Debt has no impact on diluted net income per common share unless the average price of the Company's common stock exceeds the conversion price because the Company is required to settle the principal amount of the Convertible Debt in cash upon conversion.  

12

The following is the weighted average conversion price per share used in calculating the dilutive effect (see Note 6 for details on the Convertible Debt):

	Three Months Ended December 31,				Nine Months Ended December 31,
	2023		2022		2023		2022
2015 Senior Convertible Debt	$	28.95	$	29.52	$	29.10	$	29.65
2017 Senior Convertible Debt	$	45.14	$	46.03	$	45.38	$	46.23
2020 Senior Convertible Debt	$	91.78	$	92.74	$	92.05	$	92.91
2017 Junior Convertible Debt(1)	$	—	$	45.22	$	44.81	$	45.42

(1) The weighted average conversion price per share for the 2017 Junior Convertible Debt was prior to the settlement of the outstanding principal amount in May 2023.

Total	$	5,707.2

Ranking of Convertible Debt - Each series of Convertible Debt is an unsecured obligation which is subordinated in right of payment to the amounts outstanding under the Company's Senior Indebtedness. The Senior Subordinated Convertible Debt is subordinated to the Senior Indebtedness; ranks senior to the Company's indebtedness that is expressly subordinated in right of payment to it; ranks equal in right of payment to any of the Company's unsubordinated indebtedness that does not provide that it is senior to the Senior Subordinated Convertible Debt; ranks junior in right of payment to any of the Company's secured and unsecured unsubordinated indebtedness to the extent of the value of the assets securing such indebtedness; and is structurally subordinated to all indebtedness and other liabilities of the Company's subsidiaries.

Summary of Conversion Features - Each series of Convertible Debt is convertible, subject to certain conditions, into cash, shares of the Company's common stock or a combination thereof, at the Company's election, at specified conversion rates (see table below), adjusted for certain events including the declaration of cash dividends. Except during the three-month period immediately preceding the maturity date of the applicable series of Convertible Debt, each series of Convertible Debt is convertible only upon the occurrence of (i) such time as the closing price of the Company's common stock exceeds the applicable conversion price (see table below) by 130% for 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter, (ii) during the 5 business day period after any 10 consecutive trading day period, or the measurement period, in which the trading price per $1,000 principal amount of notes of a given series for each trading day of the measurement period was less than 98% of the product

14

of the last reported sale price of the Company's common stock and the applicable conversion rate on each such trading day, or (iii) upon the occurrence of certain corporate events specified in the indenture of such series of Convertible Debt. In addition, for each series, with the exception of the 2020 Senior Convertible Debt, if at the time of conversion the applicable price of the Company's common stock exceeds the applicable conversion price at such time, the applicable conversion rate will be increased by up to an additional maximum incremental shares rate, as determined pursuant to a formula specified in the indenture for the applicable series of Convertible Debt, and as adjusted for cash dividends paid since the issuance of such series of Convertible Debt. However, in no event will the applicable conversion rate exceed the applicable maximum conversion rate specified in the indenture for the applicable series of Convertible Debt (see table below). On April 1, 2022, the Company irrevocably elected cash settlement for the principal amount of its Convertible Debt.

The following table sets forth the applicable conversion rates adjusted for dividends declared since issuance of such series of Convertible Debt and the applicable incremental share factors and maximum conversion rates as adjusted for dividends paid since the applicable issuance date:

	Dividend adjusted rates as of December 31, 2023
	Conversion Rate	Approximate Conversion Price		Incremental Share Factor	Maximum Conversion Rate
2015 Senior Convertible Debt(1)	34.5457	$	28.95	17.2746	48.3631
2017 Senior Convertible Debt(1)	22.1521	$	45.14	11.0768	31.5669
2020 Senior Convertible Debt(1)	10.8961	$	91.78	—	15.2546

(1) As of December 31, 2023, the 2020 Senior Convertible Debt was not convertible. As of December 31, 2023, the holders of each of the 2015 Senior Convertible Debt and 2017 Senior Convertible Debt have the right to convert their notes between January 1, 2024 and March 31, 2024 because the Company's common stock price has exceeded the applicable conversion price for such series by 130% for the specified period of time during the quarter ended December 31, 2023. As of December 31, 2023, the adjusted conversion rate for the 2015 Senior Convertible Debt and the 2017 Senior Convertible Debt would be increased to 46.2753 shares of common stock and 27.6841 shares of common stock, respectively, per $1,000 principal amount of notes based on the closing price of $90.18 per share of common stock to include an additional maximum incremental share rate per the terms of the applicable indenture. As of December 31, 2023, each of the 2015 Senior Convertible Debt and 2017 Senior Convertible Debt had a conversion value in excess of par of $21.4 million and $56.9 million, respectively.

With the exception of the 2020 Senior Convertible Debt, which became redeemable by the Company after November 20, 2022, the Company may not redeem any series of Convertible Debt prior to the relevant maturity date and no sinking fund is provided for any series of Convertible Debt. Under the terms of the applicable indenture, the Company may repurchase any series of Convertible Debt in the open market or through privately negotiated exchange offers. Upon the occurrence of a fundamental change, as defined in the applicable indenture of such series of Convertible Debt, holders of such series may require the Company to purchase all or a portion of their Convertible Debt for cash at a price equal to 100% of the principal amount plus any accrued and unpaid interest.

(2) The Company settled portions of its 2017 Senior Convertible Debt in privately negotiated transactions that are accounted for as induced conversions.

(3) The Company used borrowings under its Revolving Credit Facility to finance a portion of such settlement.

(4) The Company settled portions of its 2015 Senior Convertible Debt and 2017 Senior Convertible Debt, and the outstanding principal amount of its 2017 Junior Convertible Debt in privately negotiated transactions that are accounted for as induced conversions.

Senior Credit Facilities

In August 2023, the amended and restated Credit Agreement, dated as of December 16, 2021, was amended by the first incremental term loan amendment, dated as of August 31, 2023. Pursuant to this amendment, the Company borrowed an aggregate principal amount of $750.0 million under the new 2025 Term Loan Facility bearing interest at the Adjusted Term SOFR Rate, plus a margin of 1.125% to 1.5%, or Alternate Base Rate, plus a margin of 0.125% to 0.5%, with a maturity date of August 31, 2025. The interest rate margins are determined based on the Company's credit rating.

Commercial Paper

In September 2023, the Company established a Commercial Paper program under which the Company may issue short-term unsecured promissory notes up to a maximum principal amount outstanding at any time of $2.75 billion with a maturity of up to 397 days from the date of issue. The Company's obligations with respect to the payment of the Commercial Paper are guaranteed by certain of its subsidiaries. The Commercial Paper will be sold at a discount from par or alternatively, will be sold at par and bear interest rates that will vary based on market conditions and the time of issuance. Outstanding Commercial Paper reduces the amounts that would otherwise be available to borrow under the Company's Revolving Credit Facility. As of December 31, 2023, the Company had $647.0 million of principal amount of Commercial Paper outstanding. The weighted-average interest rate of the Company's outstanding Commercial Paper was 5.64% as of December 31, 2023.

Note 7. Fair Value of Financial Instruments

Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants.  As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability.  As a basis for considering such assumptions, the Company utilizes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level 1-Observable inputs such as quoted prices in active markets;

Level 2-Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and

Level 3-Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

16

The carrying amount of cash equivalents approximates fair value because their maturity is less than three months. Management believes the carrying amount of the equity investments materially approximated fair value at December 31, 2023 based upon unobservable inputs. The fair values of these investments have been determined as Level 3 fair value measurements. The carrying amount of accounts receivable, accounts payable and accrued liabilities approximates fair value due to the short-term maturity of the amounts and are considered Level 2 in the fair value hierarchy.  

The fair value of the Company's Revolving Credit Facility, the 2025 Term Loan Facility, and the Commercial Paper, is estimated using discounted cash flow analysis, based on the Company's current incremental borrowing rates for similar types of borrowing arrangements. Based on the borrowing rates currently available to the Company for bank loans with similar terms and average maturities, the fair value of the Company's Revolving Credit Facility, the 2025 Term Loan Facility, and the Commercial Paper at December 31, 2023 approximated the carrying value excluding debt discounts and debt issuance costs and are considered Level 2 in the fair value hierarchy. The Company measures the fair value of its Convertible Debt and Senior Notes for disclosure purposes. These fair values are based on observable market prices for this debt, which is traded in less active markets and are therefore classified as a Level 2 fair value measurement.

The following table shows the carrying amounts and fair values of the Company's debt obligations (in millions):

	December 31, 2023				March 31, 2023
	Carrying Amount(1)		Fair Value		Carrying Amount(1)		Fair Value

Note 10. Commitments and Contingencies

Purchase Commitments

The Company's purchase commitments primarily consist of agreements for the purchase of property, plant and equipment and other goods and services including wafer purchase obligations with the Company's wafer foundries, and manufacturing supply capacity reservation commitments.

Total purchase commitments as of December 31, 2023, are as follows (in millions):

Fiscal Year Ending March 31,	Purchase Commitments
2024	$	309.8
2025	332.6
2026	233.9
2027	197.9
2028	170.3
Thereafter	197.0
Total	$	1,441.5

Indemnification Contingencies

The Company's technology license agreements generally include an indemnification clause that indemnifies the licensee against liability and damages (including legal defense costs) arising from any claims of patent, copyright, trademark or trade secret infringement by the Company's proprietary technology.  The terms of these indemnification provisions approximate the terms of the outgoing technology license agreements, which are typically perpetual unless terminated by either party for breach. The possible amount of future payments the Company could be required to make based on agreements that specify indemnification limits, if such indemnifications were required on all of these agreements, is approximately $189.0 million. There are some licensing agreements in place that do not specify indemnification limits. As of December 31, 2023, the Company had not recorded any liabilities related to these indemnification obligations and the Company believes that any amounts that it may be required to pay under these agreements in the future will not have a material adverse effect on its financial position, cash flows or results of operations.

Warranty Costs and Product Liabilities

The Company accrues for known product-related claims if a loss is probable and can be reasonably estimated. During the periods presented, there have been no material accruals or payments regarding product warranty or product liability. Historically, the Company has experienced a low rate of payments on product claims. Although the Company cannot predict the likelihood or amount of any future claims, the Company does not believe these claims will have a material adverse effect on its financial condition, results of operations or liquidity.

Legal Matters

In the ordinary course of the Company's business, it is exposed to various legal actions as a result of contracts, product liability, customer claims, pricing or royalty disputes with customers and licensees, governmental investigations and other matters. The Company is involved in a limited number of these legal actions, both as plaintiff and defendant, with respect to the foregoing types of matters. Consequently, the Company could incur uninsured liability in any of these legal actions.  The Company also periodically receives notifications from various third parties alleging infringement of patents or other intellectual property rights, or from customers requesting reimbursement for various costs. With respect to pending legal actions to which the Company is a party and other claims, although the outcomes are generally not determinable, the Company believes that the ultimate resolution of these matters will not have a material adverse effect on its financial position, cash flows or results of operations. Litigation, governmental investigations and disputes relating to the semiconductor industry are not uncommon, and the Company is, from time to time, subject to such litigation, governmental investigations and disputes.  As a result, no assurances can be given with respect to the extent or outcome of any such litigation, governmental investigations or disputes in the future.

The Company accrues for claims and contingencies when losses become probable and reasonably estimable. As of the end of each applicable reporting period, the Company reviews each of its matters and, where it is probable that a liability has been or will be incurred, the Company accrues for all probable and reasonably estimable losses. Where the Company can

20

reasonably estimate a range of losses it may incur regarding such a matter, the Company records an accrual for the amount within the range that constitutes its best estimate. If the Company can reasonably estimate a range but no amount within the range appears to be a better estimate than any other, the Company uses the amount that is the low end of such range. As of December 31, 2023, the Company's estimate of the aggregate potential liability for legal matters that is possible but not probable is approximately $150.0 million in excess of amounts accrued.

As a result of its acquisition of Atmel, which closed April 4, 2016, the Company became involved with the following legal matter:

Individual Labor Actions by former LFR Employees. In June 2010, Atmel Rousset sold its wafer manufacturing business in Rousset, France to LFoundry GmbH (LF), the German parent of LFoundry Rousset (LFR). LFR then leased the Atmel Rousset facility to conduct the manufacture of wafers. More than three years later, LFR became insolvent and later liquidated. In the wake of LFR's insolvency and liquidation, over 500 former employees of LFR filed individual labor actions against Atmel Rousset in a French labor court, and in 2019 a French labor court dismissed all of the employees’ claims against Atmel Rousset. In 2020, the Plaintiffs filed appeals with the Court of Appeals requesting reconsideration of the earlier dismissals. In December 2022, the Court of Appeals dismissed these appeals and held that there had been no co-employment of the plaintiffs by Atmel Rousset and LFoundry Rousset. However, in 2017 these same claims were filed by this same group of employees in a regional court in France against Microchip Technology Incorporated and Atmel Corporation. The Company, and the other defendant entities, believe that each of these actions is entirely devoid of merit, and, further, that any assertion by any of the Claimants of a co-employment relationship with any of these entities is based substantially on the same specious arguments that the Paris Commercial Court summarily rejected in 2014 in related proceedings. The defendant entities therefore intend to defend vigorously against each of these claims. Additionally, complaints have been filed in a regional court in France on behalf of the same group of employees against Microchip Technology Rousset, Atmel Switzerland Sarl, Atmel Corporation and Microchip Technology Incorporated alleging that the sale of the Atmel Rousset production unit to LF was fraudulent and should be voided. These claims are specious and the defendant entities therefore intend to defend vigorously against these claims.

Note 11. Income Taxes

The Company accounts for income taxes in accordance with ASC 740. The provision for income taxes is attributable to U.S. federal, state, and foreign income taxes. The Company’s effective tax rate for the interim period ended December 31, 2023 is 19.03% and is based on an estimated annual effective tax rate including the tax effect of items required to be recorded discretely in the interim periods in which those items occur. A comparison of the Company’s effective tax rates for the nine months ended December 31, 2023 and December 31, 2022 is not meaningful due to the amount of pre-tax income, and income tax expense recorded during the prior period.

The Company's effective tax rate is different than the statutory rates in the U.S. due to foreign income taxed at different rates than the U.S., changes in uncertain tax benefit positions, changes to valuation allowances, generation of tax credits, and the impact of Global Intangible Low Tax Income (GILTI) in the U.S. In addition, the Company has numerous tax holidays it receives related to its Thailand manufacturing operations based on its investment in property, plant and equipment in Thailand. The Company's tax holiday periods in Thailand expire at various times in the future, however, the Company actively seeks to obtain new tax holidays. The material components of foreign income taxed at a rate lower than the U.S. are earnings accrued in Thailand, Malta, and Ireland.

The Company files U.S. federal, U.S. state, and foreign income tax returns.  For U.S. federal, and in general for U.S. state tax returns, the fiscal 2007 and later tax years remain open for examination by tax authorities.  For foreign tax returns, the Company is generally no longer subject to income tax examinations for years prior to fiscal 2007.

In September 2021, the Company received a Statutory Notice of Deficiency (2007 to 2012 Notice) from the United States Internal Revenue Service (IRS) for fiscal 2007 through fiscal 2012. The disputed amounts largely relate to transfer pricing matters. In December 2021, the Company filed a petition in the U.S. Tax Court challenging the 2007 to 2012 Notice.

In September 2023, the Company received a Revenue Agent Report (RAR) from the IRS for fiscal 2013 and fiscal 2016. In October 2023, the Company received a Statutory Notice of Deficiency (2014 to 2015 Notice) from the IRS for fiscal 2014 and fiscal 2015. The disputed amounts for fiscal 2013 to fiscal 2016 largely relate to transfer pricing matters. In December 2023, the Company filed a petition in the U.S. Tax Court challenging the 2014 to 2015 Notice.

21

In May 2023, the Company received a proposed income adjustment from the Malaysian Inland Revenue Board (IRB) for fiscal 2020. In December 2023, the Company received a Notice of Assessment from the IRB asserting the same proposed income adjustment. If the adjustment is upheld by the highest court that has jurisdiction over this matter in Malaysia, it could result in income taxes up to $360.0 million, exclusive of interest and penalties, which may result in additional material exposure. The disputed amounts largely relate to the characterization of certain assets. Depending on the outcome of the IRB audit, the Company may need to adjudicate this matter in Malaysia, and if the Company does, the Company may be required to pay the assessment and then, upon a series of favorable court rulings, request a refund of the amount. The timing of adjudicating this matter is uncertain but could commence in the next 12 months.

The Company firmly believes that the assessments described above are without merit and plan to pursue all available administrative and judicial remedies necessary to resolve these matters. The Company intends to vigorously defend the positions and the Company is confident in its ability to prevail on the merits. The Company regularly assesses the likelihood of adverse outcomes resulting from examinations such as these to determine the adequacy of the Company's tax reserves. The ultimate outcome of disputes of this nature is uncertain, and if the IRS and IRB were to prevail on their assertions, the assessed tax, penalties, and deficiency interest could have a material adverse impact on the Company's financial position, results of operations or cash flows.

Note 13. Stock Repurchase Activity

In November 2021, the Company's Board of Directors approved a new stock repurchase program to repurchase up to $4.00 billion of the Company's common stock in the open market or in privately negotiated transactions. There is no expiration date associated with the repurchase program. During the three and nine months ended December 31, 2023, the Company purchased approximately 1.4 million shares and 7.4 million shares, respectively, of its common stock for a total cost of $115.0 million and $598.5 million, respectively, including the 1% excise tax on stock repurchases enacted by the Inflation Reduction Act of 2022 (Inflation Reduction Act). As of December 31, 2023, approximately $2.03 billion remained available for repurchases under the program. Shares repurchased are recorded as treasury shares and are used to fund share issuance requirements under the Company's equity incentive plans. As of December 31, 2023, the Company had approximately 37.4 million treasury shares.

Introduction

The following discussion should be read in conjunction with the condensed consolidated financial statements and the related notes that appear elsewhere in this document.

We begin our Management's Discussion and Analysis of Financial Condition and Results of Operations with a summary of business and macroeconomic developments followed by a summary of our overall business strategy to provide an overview of the goals and overall direction of our business. This is followed by a discussion of the Critical Accounting Policies and Estimates that we believe are important to understanding the assumptions and judgments incorporated in our reported financial results. We then discuss our Results of Operations for the three and nine months ended December 31, 2023 compared to the three and nine months ended December 31, 2022, followed by an analysis of changes in our balance sheet and cash flows, and discuss our financial commitments in the section titled "Liquidity and Capital Resources."

Business and Macroeconomic Environment

While strong customer demand for our products outpaced capacity in fiscal 2023, many of our customers felt the effects of slowing economic activity, increasing business uncertainty, persistent inflation and higher interest rates in the March 2023 quarter which continued through the first nine months of fiscal 2024. During the December 2023 quarter, business conditions globally were weaker than expected as our customers continued to respond to the effects of increasing business uncertainty and slowing economic activity. As a result, we continued to receive requests to push out or cancel backlog resulting from customer actions to reduce inventory levels and we expect such weak business conditions to continue in the March 2024 quarter. To help manage our inventory levels due to these adverse economic conditions, during each of the March 2024 and June 2024 quarters, we are reducing production levels and implementing up to two weeks of shutdown days in our global fabrication facilities. Consistent with the weak macroeconomic environment, most of our factory expansion activity remains paused and we have reduced our planned capital investments through fiscal 2025.

In response to industry capacity conditions improving and our product lead times reducing, we discontinued our Preferred Supply Program in February 2024 with respect to all new orders. We had initially launched our Preferred Supply Program in February 2021 to provide our customers with prioritized capacity when product demand in the industry significantly exceeded supply. Since the March 2022 quarter, we have been entering into long-term supply agreements (LTSAs) with certain of our customers for products that will be shipped in future periods. We also entered into certain LTSAs with key suppliers.

Strategy

We develop, manufacture and sell smart, connected and secure embedded control solutions used by our customers for a wide variety of applications. Our strategic focus includes general purpose and specialized 8-bit, 16-bit, and 32-bit mixed-signal microcontrollers, microprocessors, analog, FPGA, and memory products. With over 30 years of technology leadership, our broad product portfolio is a Total System Solution (TSS) for our customers that can provide a large portion of the silicon requirements in their applications. TSS is a combination of hardware, software and services which help our customers increase their revenue, reduce their costs and manage their risks compared to other solutions. Our synergistic product portfolio empowers disruptive growth trends, including 5G, data centers, sustainability, Internet of Things (IoT) and edge computing, advanced driver assist systems (ADAS) and autonomous driving, and electric vehicles, in key end markets such as automotive, aerospace and defense, communications, consumer appliances, data centers and computing, and industrial.

Our manufacturing operations include wafer fabrication, wafer probe, assembly and test.  In fiscal 2023, we announced our intent to expand our production capacity in the U.S. In particular, we have continued our multi-year $800 million capacity expansion plan at Fab 4 in Gresham, Oregon and we plan to invest $880 million to expand our silicon carbide (SiC) and silicon production capacity, including the production of 8-inch wafers at Fab 5 in Colorado Springs, Colorado. The ownership of a substantial portion of our manufacturing resources is an important component of our business strategy, enabling us to maintain a high level of manufacturing control, resulting in us being one of the lowest cost producers in the embedded control industry.  By owning wafer fabrication facilities and our assembly and test operations, and by employing statistical techniques (statistical process control, designed experiments and wafer level monitoring), we have been able to achieve and maintain high production yields.  Direct control over manufacturing resources allows us to shorten our design and production cycles.  This control also allows us to capture a portion of the wafer manufacturing and assembly and testing profit margin. We outsource a significant portion of our manufacturing requirements to third parties and the amount of our outsourced manufacturing has increased in recent years due to our acquisitions of Microsemi and other companies that outsourced all or substantial portions of their manufacturing.

26

We employ proprietary design and manufacturing processes in developing our embedded control products.  We believe our processes afford us both cost-effective designs in existing and derivative products and greater functionality in new product designs.  While many of our competitors develop and optimize separate processes for their logic and memory product lines, we use a common process technology for both mixed-signal microcontroller and non-volatile memory products.  This allows us to more fully leverage our process research and development costs and to deliver new products to market more rapidly.  Our engineers utilize advanced computer-aided design tools and software to perform circuit design, simulation and layout, and our in-house photomask and wafer fabrication facilities enable us to rapidly verify design techniques by processing test wafers quickly and efficiently. 

We are committed to continuing our investment in new and enhanced products, including development systems, and in our design and manufacturing process technologies.  We believe these investments are significant factors in maintaining our competitive position.  Our current research and development activities focus on the design of new mixed-signal microcontrollers, digital signal controllers, memory, analog and mixed-signal products, FPGAs, timing systems, Flash-IP, development systems, software and application-specific software libraries.  We are also developing new design and process technologies to achieve further cost reductions and performance improvements in our products. 

We market and sell our products worldwide primarily through a network of direct sales personnel and distributors. Our direct sales force focuses on a wide variety of strategic accounts in three geographical markets: the Americas, Europe and Asia.  We currently maintain sales and technical support centers in major metropolitan areas in all three geographic markets. We believe that a strong technical service presence is essential to the continued development of the embedded control market.  Many of our CEMs, ESEs, and sales managers have technical degrees or backgrounds and have been previously employed in high technology environments.  We believe that the technical and business knowledge of our sales force is a key competitive advantage in the sale of our products.  The primary mission of our ESE team is to provide technical assistance to customers and to conduct periodic training sessions for our sales team.  ESEs also frequently conduct technical seminars and workshops in major cities around the world or through online webcasts. Our licensing division has dedicated sales, technology, design, product, test and reliability personnel that support the requirements of our licensees.

Net Sales

We operate in two industry segments and engage primarily in the design, development, manufacture and sale of semiconductor products as well as the licensing of our SuperFlash and other technologies.  We sell our products to distributors and OEMs in a broad range of markets, perform ongoing credit evaluations of our customers and generally require no collateral.  In certain circumstances, a customer's financial condition may require collateral, and, in such cases, the collateral would be typically provided in the form of letters of credit.

The following table summarizes our net sales for the periods covered by this report (dollars in millions):

	Three Months Ended December 31,						Nine Months Ended December 31,
	2023		2022		Change		2023		2022		Change
Net sales	$	1,765.7	$	2,169.2	(18.6)	%	$	6,308.6	$	6,206.0	1.7	%

The decrease in net sales in the three months ended December 31, 2023 compared to the three months ended December 31, 2022 was primarily due to adverse economic conditions, including slowing economic activity, increasing business uncertainty, persistent inflation and higher interest rates. The increase in net sales in the nine months ended December 31, 2023 compared to the nine months ended December 31, 2022 was primarily due to our ability to satisfy our backlog of customer orders as more capacity became available during the first and second quarters of fiscal 2024. Additionally, semiconductor industry conditions have resulted in increased costs throughout our supply chain, which we have been generally passing on to our customers in the form of price increases. Our price increases were implemented at various times and in various amounts throughout fiscal 2023 with respect to our very broad range of customers and products. These price increases also contributed to the increase in net sales during the nine months ended December 31, 2023 compared to the nine months ended December 31, 2022. Due to the complexity of the implementation of the price increases and the changes in product, geographic and customer mix, we are not able to quantify the impact of the price increases on our net sales. Due to the size, complexity and diversity of our customer base, we are not able to quantify any material factor contributing to the changes other than the net demand fluctuations in the end market we serve. See our "Business and Macroeconomic Environment" discussion above for further information on our business outlook.

Other factors that we believe contributed to changes in our reported net sales for the three and nine months ended December 31, 2023 compared to the three and nine months ended December 31, 2022 and which are drivers of long-term trends in our net sales but which factors we are not able to quantify include:

•semiconductor industry conditions;

•our various new product offerings that have increased our served available market;

•customers’ increasing needs for the flexibility offered by our programmable solutions; and

•increasing semiconductor content in our customers’ products through our TSS product portfolio.

We sell a large number of products to a large and diverse customer base and there was not any single product or customer that accounted for a material portion of the change in our net sales in the three and nine months ended December 31, 2023 or the three and nine months ended December 31, 2022.

Net sales by product line for the periods covered by this report were as follows (dollars in millions):

	Three Months Ended December 31,						Nine Months Ended December 31,
	2023		%	2022		%	2023		%	2022		%
Mixed-signal Microcontrollers	$	995.2	56.3	$	1,221.3	56.3	$	3,577.0	56.7	$	3,463.8	55.9
Analog	430.6		24.4	606.5		28.0	1,687.2		26.7	1,759.0		28.3
Other	339.9		19.3	341.4		15.7	1,044.4		16.6	983.2		15.8
Total net sales	$	1,765.7	100.0	$	2,169.2	100.0	$	6,308.6	100.0	$	6,206.0	100.0

Mixed-signal Microcontrollers

Our mixed-signal microcontroller product line represents the largest component of our total net sales.  Mixed-signal microcontrollers and associated application development systems accounted for approximately 56.3% and 56.7% of our net sales for the three and nine months ended December 31, 2023, respectively, compared to approximately 56.3% and 55.9% of our net sales for the three and nine months ended December 31, 2022, respectively.

28

Net sales of our mixed-signal microcontroller products decreased 18.5% and increased 3.3% in the three and nine months ended December 31, 2023, respectively, compared to the three and nine months ended December 31, 2022. These changes in net sales were primarily due to adverse economic conditions, and were offset by our available capacity for our mixed-signal microcontroller products and our price increases.

Historically, average selling prices in the semiconductor industry decrease over the life of any particular product. However, the overall average selling prices of our mixed-signal microcontroller products have increased in recent periods and have remained relatively stable over time due to the proprietary nature of these products.  We have in the past been able to, and expect in the future to be able to, moderate average selling price declines in our mixed-signal microcontroller product lines by introducing new products with more features and higher prices.  

Analog

Our analog product line includes analog, interface, mixed-signal and timing products. Our analog product line accounted for approximately 24.4% and 26.7% of our net sales for the three and nine months ended December 31, 2023, respectively, compared to approximately 28.0% and 28.3% of our net sales for the three and nine months ended December 31, 2022, respectively.

Net sales from our analog product line decreased 29.0% and 4.1% in the three and nine months ended December 31, 2023, respectively, compared to the three and nine months ended December 31, 2022, primarily due to adverse economic conditions, which were partially offset by our available capacity for our analog products and our price increases.

We consider a majority of the products in our analog product line to be proprietary in nature, where prices are relatively stable, similar to the pricing stability experienced in our mixed-signal microcontroller products. The non-proprietary portion of our analog product line will experience price fluctuations, driven primarily by the current supply and demand for those products.

Other

Our other product line includes FPGA products, royalties associated with licenses for the use of our SuperFlash and other technologies, sales of our intellectual property, fees for engineering services, memory products, timing systems, manufacturing services (wafer foundry and assembly and test subcontracting), legacy application specific integrated circuits, and certain products for aerospace applications. Revenue from these services and products accounted for approximately 19.3% and 16.6% of our net sales for the three and nine months ended December 31, 2023, respectively, compared to approximately 15.7% and 15.8% of our net sales for the three and nine months ended December 31, 2022, respectively.

Net sales related to these services and products remained flat in the three months ended December 31, 2023 compared to the three months ended December 31, 2022 and increased 6.2% in the nine months ended December 31, 2023 compared to the nine months ended December 31, 2022. Net sales during these periods were primarily affected by adverse economic conditions, and by our available capacity for our products and our price increases. Net sales of our other product line can fluctuate over time based on general economic and semiconductor industry conditions as well as changes in demand for our FPGA products, licenses, engineering services, memory products, timing systems, and manufacturing services (wafer foundry and assembly and test subcontracting).

Distribution

Distributors accounted for approximately 44% and 48% of our net sales in the three and nine months ended December 31, 2023, respectively, and approximately 48% and 47% of our net sales in the three and nine months ended December 31, 2022, respectively. The decrease in net sales to distributors in the three months ended December 31, 2023 compared to the three months ended December 31, 2022 was primarily due to efforts by our distributors to manage their inventory levels. With the exception of Arrow Electronics, our largest distributor, which made up 12% and 10% of our net sales in the nine months ended December 31, 2023 and in the nine months ended December 31, 2022, respectively, no other distributor or direct customer accounted for more than 10% of our net sales in the nine months ended December 31, 2023 or in the nine months ended December 31, 2022. Our distributors focus primarily on servicing the product requirements of a broad base of diverse customers. We believe that distributors provide an effective means of reaching this broad and diverse customer base.  We believe that customers recognize Microchip for its products and brand name and use distributors as an effective supply channel.

29

Generally, we do not have long-term agreements with our distributors and we, or our distributors, may terminate our relationships with each other with little or no advance notice, with the exception of certain orders placed under our original Preferred Supply Program or otherwise designated as non-cancellable.  The loss of, or the disruption in the operations of, one or more of our distributors could reduce our future net sales in a given quarter and could result in an increase in inventory returns.

At December 31, 2023, our distributors maintained 37 days of inventory of our products compared to 24 days at March 31, 2023.  Over the past ten fiscal years, the days of inventory maintained by our distributors have fluctuated between approximately 17 days and 40 days.  Inventory holding patterns at our distributors may have a material impact on our net sales.

Sales by Geography

Sales by geography for the periods covered by this report were as follows (dollars in millions):

	Three Months Ended December 31,						Nine Months Ended December 31,
	2023		%	2022		%	2023		%	2022		%
Americas	$	510.2	28.9	$	567.4	26.2	$	1,808.2	28.7	$	1,588.7	25.6
Europe	414.5		23.5	428.6		19.8	1,531.0		24.3	1,242.0		20.0
Asia	841.0		47.6	1,173.2		54.0	2,969.4		47.0	3,375.3		54.4
Total net sales	$	1,765.7	100.0	$	2,169.2	100.0	$	6,308.6	100.0	$	6,206.0	100.0

Americas sales include sales to customers in the U.S., Canada, Central America and South America. Sales to foreign customers accounted for approximately 75% of our total net sales in each of the three and nine months ended December 31, 2023 compared to approximately 77% of our total net sales in each of the three and nine months ended December 31, 2022. The decreases in Asia net sales in the three and nine months ended December 31, 2023 compared to the three and nine months ended December 31, 2022 were due to unfavorable business conditions and weakening demand in the China market. The changes in net sales in the Americas and Europe in the three and nine months ended December 31, 2023 compared to the three and nine months ended December 31, 2022 were primarily due to adverse economic conditions, and were offset by our available capacity due to the weakening demand environment in Asia. Substantially all of our foreign sales are U.S. dollar denominated. Our sales force in the Americas and Europe supports a significant portion of the design activity for products which are ultimately shipped to Asia.

Gross Profit

Our gross profit in the three months ended December 31, 2023 was $1.12 billion, or 63.4% of net sales, compared to $1.47 billion, or 67.8% of net sales, in the three months ended December 31, 2022. Our gross profit in the nine months ended December 31, 2023 was $4.21 billion, or 66.7% of net sales, compared to $4.18 billion, or 67.3% of net sales, in the nine months ended December 31, 2022.

The primary reason for the decrease in gross profit in the three months ended December 31, 2023 compared to the three months ended December 31, 2022 was an unfavorable net impact of sales volume, product mix and average gross profit per unit of $300.0 million in the three months ended December 31, 2023. The primary reason for the increase in gross profit in the nine months ended December 31, 2023 compared to the nine months ended December 31, 2022 was a favorable net impact of product mix and average gross profit per unit of $96.2 million in the nine months ended December 31, 2023. The net impact of product mix and average gross profit per unit may fluctuate over time due to the mix of sales volumes of lower or higher margin products, changes in selling prices, and fluctuations in product costs. We are not able to separately quantify these impacts on our gross profit. The net impact to our gross profit from inventory reserve charges was an adverse impact of $20.9 million and $25.0 million in the three and nine months ended December 31, 2023, respectively, compared to the three and nine months ended December 31, 2022. The gross margin impact of changes in licensing revenue, which has no associated cost of sales, was an adverse impact of $20.2 million and $42.7 million in the three and nine months ended December 31, 2023, respectively, compared to the three and nine months ended December 31, 2022. The impact of unabsorbed capacity charges in the three and nine months ended December 31, 2023 was not material.

Our overall inventory levels were $1.31 billion at December 31, 2023, compared to $1.32 billion at March 31, 2023. We maintained 185 days of inventory on our balance sheet at December 31, 2023 compared to 169 days of inventory at March 31, 2023. Our inventory level was slightly lower as a result of our efforts to balance manufacturing production, customer

30

demand and inventory levels. Our inventory levels are impacted by timing of shipment activity in the quarter, the timing of receipt of raw materials, foundry wafers, and strategic last time buy materials and completion of finished goods.

We operate assembly and test facilities in Thailand, the Philippines, and other locations throughout the world. Approximately 59% and 58% of our assembly requirements were performed in our internal assembly facilities during the three and nine months ended December 31, 2023, respectively, compared to approximately 59% during each of the three and nine months ended December 31, 2022. Approximately 72% and 71% of our test requirements were performed in our internal test facilities during the three and nine months ended December 31, 2023, respectively, compared to approximately 68% and 67% during the three and nine months ended December 31, 2022, respectively. The percentage of our assembly and test operations that are performed internally fluctuates over time based on supply and demand conditions in the semiconductor industry, our internal capacity capabilities and our acquisition activities. We believe that the assembly and test operations performed at our internal facilities provide us with significant cost savings compared to third-party contractor assembly and test costs, as well as increased control over these portions of the manufacturing process. We plan to continue to invest in assembly and test equipment to increase our internal capacity capabilities and transition certain outsourced assembly and test capacity to our internal facilities.

We rely on outside wafer foundries for a significant portion of our wafer fabrication requirements. Approximately 64% and 65% of our net sales came from products that were produced at outside wafer foundries during the three and nine months ended December 31, 2023, respectively, compared to approximately 63% during each of the three and nine months ended December 31, 2022. These percentages may vary from quarter to quarter based on supply and demand conditions in the market.

We anticipate that our gross margins will fluctuate over time, driven primarily by capacity utilization levels, the overall product mix of mixed-signal microcontroller, analog, FPGA products, memory products, and technology licensing revenue and the percentage of net sales of each of these products in a particular quarter, as well as manufacturing yields, fixed cost absorption, and competitive and economic conditions in the markets we serve. We continue to transition products to more advanced process technologies to reduce future manufacturing costs.

Research and Development

R&D expenses for the three months ended December 31, 2023 were $266.0 million, or 15.1% of net sales, compared to $282.4 million, or 13.0% of net sales, for the three months ended December 31, 2022. R&D expenses for the nine months ended December 31, 2023 were $857.1 million, or 13.6% of net sales, compared to $820.0 million, or 13.2% of net sales, for the nine months ended December 31, 2022. We are committed to investing in new and enhanced products, including development systems software, and in our design and manufacturing process technologies.  We believe these investments are significant factors in maintaining our competitive position.  R&D costs are expensed as incurred.  Assets purchased to support our ongoing research and development activities are capitalized when related to products which have achieved technological feasibility or that have alternative future uses and are amortized over their expected useful lives.  R&D expenses include labor, depreciation, masks, prototype wafers, and expenses for the development of process technologies, new packages, and software to support new products and design environments.

R&D expenses decreased $16.4 million, or 5.8%, for the three months ended December 31, 2023 over the same period last year.  R&D expenses increased $37.1 million, or 4.5%, for the nine months ended December 31, 2023 over the same period last year. The primary reason for the decrease in R&D expenses in the three months ended December 31, 2023 over the same period last year was due to lower employee compensation costs. The primary reason for the increase in R&D expenses in the nine months ended December 31, 2023 over the same period last year were increases in headcount and employee compensation, as well as higher product development costs.

R&D expenses fluctuate over time, primarily due to revenue and operating expense investment levels.

Selling, General and Administrative

Selling, general and administrative expenses for the three months ended December 31, 2023 were $172.2 million, or 9.8% of net sales, compared to $202.9 million, or 9.4% of net sales, for the three months ended December 31, 2022. Selling, general and administrative expenses for the nine months ended December 31, 2023 were $572.4 million, or 9.1% of net sales, compared to $594.2 million, or 9.6% of net sales, for the nine months ended December 31, 2022.  Our goal is to continue to be more efficient with our selling, general and administrative expenses. Selling, general and administrative expenses include salary expenses related to field sales, marketing and administrative personnel, advertising and promotional expenditures and

31

legal expenses as well as costs related to our direct sales force, CEMs and ESEs who work remotely from sales offices worldwide to stimulate demand by assisting customers in the selection and use of our products.

Selling, general and administrative expenses decreased $30.7 million, or 15.1%, for the three months ended December 31, 2023 over the same period last year.  Selling, general and administrative expenses decreased $21.8 million, or 3.7%, for the nine months ended December 31, 2023 over the same period last year.  The primary reason for the decreases in selling, general and administrative expenses was lower employee compensation costs.

Selling, general and administrative expenses fluctuate over time, primarily due to revenue and operating expense investment levels.

Amortization of Acquired Intangible Assets

Amortization of acquired intangible assets for the three and nine months ended December 31, 2023 was $151.3 million and $454.2 million, respectively, compared to $167.4 million and $502.5 million for the three and nine months ended December 31, 2022, respectively. The primary reason for the decreases in acquired intangible asset amortization was due to the use of accelerated amortization methods for assets placed in service in previous fiscal years.

Special Charges (Income) and Other, Net

During the three and nine months ended December 31, 2023, we incurred special charges and other, net of $1.1 million and $4.6 million, respectively, primarily related to restructuring of acquired and existing wafer fabrication operations to increase operational efficiency. During the three and nine months ended December 31, 2022, we incurred special charges and other, net of $6.5 million and earned special income and other, net of $6.1 million, respectively. The special charges and other, net incurred during the three months ended December 31, 2022, primarily related to restructuring of acquired and existing wafer fabrication operations to increase operational efficiency. The special income and other, net earned during the nine months ended December 31, 2022, primarily related to a favorable resolution of a previously accrued legal matter, partially offset by restructuring costs of acquired and existing wafer fabrication operations to increase operational efficiency.

Other Income (Expense)

Interest expense in the three and nine months ended December 31, 2023 was $49.2 million and $143.2 million, respectively, compared to $52.8 million and $156.4 million, respectively, for the three and nine months ended December 31, 2022. The primary reasons for the decreases in interest expense was due to the cumulative pay down of our debt offset by higher interest rates on our outstanding debt.

During the nine months ended December 31, 2023, and December 31, 2022, we recognized losses of $12.2 million and $8.3 million, respectively, related to the settlement of a portion of our outstanding 2015 Senior Convertible Debt, our 2017 Senior Convertible Debt, and our 2017 Junior Convertible Debt.

Provision for Income Taxes

Our provision for income taxes is attributable to U.S. federal, state, and foreign income taxes. A comparison of our tax rates for the nine months ended December 31, 2023 and December 31, 2022 is not meaningful due to the amount of pre-tax income, and income tax expense recorded during the prior period.

We are subject to taxation in many jurisdictions in which we have operations. The effective tax rates that we pay in these jurisdictions vary widely, but they are generally lower than our combined U.S. federal and state effective tax rate. Our domestic blended statutory tax rate in each of the nine months ended December 31, 2023 and December 31, 2022 was approximately 22%. Our non-U.S. blended statutory tax rates in the nine months ended December 31, 2023 and December 31, 2022 were lower than this amount. The difference in rates applicable in foreign jurisdictions results from a number of factors, including lower statutory rates, tax holidays, financing arrangements and other factors. Our effective tax rate has been and will continue to be impacted by the geographical dispersion of our earnings and losses.

Our foreign tax rate differential benefit primarily relates to our operations in Malta taxed at a 5.0% statutory tax rate and Ireland taxed at a 12.5% statutory tax rate. Additionally, our Thailand manufacturing operations are currently subject to numerous tax holidays granted to us based on our investment in property, plant, and equipment in Thailand. Our tax holiday periods in Thailand expire at various times in the future; however, we actively seek to obtain new tax holidays, otherwise we

32

will be subject to tax at the statutory tax rate of 20.0%. We do not expect the future expiration of any of our tax holiday periods in Thailand to have a material impact on our effective tax rate.

In September 2021, we received a Statutory Notice of Deficiency (2007 to 2012 Notice) from the United States Internal Revenue Service (IRS) for fiscal 2007 through fiscal 2012. The disputed amounts largely relate to transfer pricing matters. In December 2021, we filed a petition in the U.S. Tax Court challenging the 2007 to 2012 Notice.

In September 2023, we received a Revenue Agent Report (RAR) from the IRS for fiscal 2013 and fiscal 2016. In October 2023, we received a Statutory Notice of Deficiency (2014 to 2015 Notice) from the IRS for fiscal 2014 and fiscal 2015. The disputed amounts for fiscal 2013 to fiscal 2016 largely relate to transfer pricing matters. In December 2023, we filed a petition in the U.S. Tax Court challenging the 2014 to 2015 Notice.

In May 2023, we received a proposed income adjustment from the Malaysian Inland Revenue Board (IRB) for fiscal 2020. In December 2023, we received a Notice of Assessment from the IRB asserting the same proposed income adjustment. If the adjustment is upheld by the highest court that has jurisdiction over this matter in Malaysia, it could result in income taxes up to $360.0 million, exclusive of interest and penalties, which may result in additional material exposure. The disputed amounts largely relate to the characterization of certain assets. Depending on the outcome of the IRB audit, we may need to adjudicate this matter in Malaysia, and if we do, we may be required to pay the assessment and then, upon a series of favorable court rulings, request a refund of the amount. The timing of adjudicating this matter is uncertain but could commence in the next 12 months.

We firmly believe that the assessments described above are without merit and plan to pursue all available administrative and judicial remedies necessary to resolve these matters. We intend to vigorously defend our positions and we are confident in our ability to prevail on the merits. We regularly assess the likelihood of adverse outcomes resulting from examinations such as these to determine the adequacy of our tax reserves. The ultimate outcome of disputes of this nature is uncertain, and if the IRS and IRB were to prevail on their assertions, the assessed tax, penalties, and deficiency interest could have a material adverse impact on our financial position, results of operations or cash flows.

Various taxing authorities in the U.S. and other countries in which we do business are increasing their scrutiny of the tax structures employed by businesses.  Companies of our size and complexity are regularly audited by the taxing authorities in the jurisdictions in which they conduct significant operations.  For U.S. federal, and in general for U.S. state tax returns, our fiscal 2007 and later tax returns remain effectively open for examination by the taxing authorities. We are currently being audited by the tax authorities in the U.S. and in various foreign jurisdictions. At this time, we do not know what the outcome of these audits will be. We record benefits for uncertain tax positions based on an assessment of whether it is more likely than not that the tax positions will be sustained based on their technical merits under currently enacted law. If this threshold is not met, no tax benefit of the uncertain tax position is recognized. If the threshold is met, we recognize the largest amount of the tax benefit that is more than 50% likely to be realized upon ultimate settlement.

In August 2022, the U.S. government enacted the Inflation Reduction Act into law. The Inflation Reduction Act includes a new corporate alternative minimum tax (Corporate AMT) of 15.0% on the adjusted financial statement income (AFSI) of corporations with average AFSI exceeding $1.00 billion over a three-year period, as well as a 1% excise tax on the net fair market value of stock repurchases made after December 31, 2022. The Corporate AMT is effective beginning in fiscal 2024. Based on currently enacted tax laws, we do not expect the Inflation Reduction Act to have a material impact on our tax expense, cash taxes, or effective tax rate.

As of December 31, 2023, 25 countries have enacted various aspects of the Organisation for Economic Co-operation and Development’s Base Erosion and Profit Shifting Project to ensure that multinational enterprises pay a GMT. In 24 of those countries, the GMT is effective for tax years beginning in our fiscal 2025. Based on currently enacted law, the impact of GMT on the fiscal 2025 results is not expected to be material.

Liquidity and Capital Resources

We had $281.0 million in cash and cash equivalents at December 31, 2023, an increase of $47.0 million from the March 31, 2023 balance.  

33

Operating Activities

Net cash provided by operating activities was $2.46 billion in the nine months ended December 31, 2023 primarily due to higher net income of $1.75 billion, adjusted for non-cash and non-operating charges of $866.4 million and net cash outflows of $155.9 million from changes in our operating assets and liabilities. The primary drivers of the changes in operating assets and liabilities in the nine months ended December 31, 2023 include an increase in trade accounts receivable driven primarily by timing of shipments and collections, a decrease in accounts payable due to lower spending in adverse economic conditions, and a decrease in income tax payable, offset by increases in accrued and other liabilities driven by higher deferred revenue and sales related reserves, including cash collected from customers under our LTSAs, and a decrease in inventories related to our efforts to balance manufacturing production, customer demand and inventory levels. The cash collected from these LTSAs is refundable when customers fulfill their purchase commitments. In future periods, we expect cash inflows under these LTSAs to decrease, and cash outflows to increase as amounts are refunded to customers (see "Note 4. Net Sales" to our condensed consolidated financial statements). Net cash provided by operating activities was $2.91 billion in the nine months ended December 31, 2022 primarily due to net income of $1.63 billion, adjusted for non-cash and non-operating charges of $1.09 billion and net cash inflows of $190.3 million from changes in our operating assets and liabilities.

Investing Activities

Net cash used in investing activities was $320.9 million in the nine months ended December 31, 2023 compared to $448.7 million in the nine months ended December 31, 2022. During the nine months ended December 31, 2023 and December 31, 2022, net investing activities primarily related to capital purchases and investments in other assets.

Our level of capital expenditures varies from time to time as a result of actual and anticipated business conditions. Capital expenditures in the nine months ended December 31, 2023 were $245.0 million compared to $373.5 million in the nine months ended December 31, 2022. Capital expenditures were primarily for the expansion of production capacity and the addition of research and development equipment. Consistent with the slowing macroeconomic environment in the first nine months of fiscal 2024, we have paused most of our factory expansion actions and reduced our planned capital investments through fiscal 2025. We currently intend to invest between $200 million and $300 million in equipment and facilities during the next 12 months. We believe that the capital expenditures anticipated to be incurred over the next 12 months will provide sufficient manufacturing capacity to support the growth of our production capabilities for our new products and technologies and to bring in-house more of the assembly and test operations that are currently outsourced. We expect to finance our capital expenditures through our existing cash balances and cash flows from operations.  In February 2023, we announced our plan to invest $880 million over the next several years to expand our SiC and silicon production capacity, including the production of 8-inch wafers, at our Fab 5 facility. In August 2022, the U.S. government enacted the CHIPS Act which is to provide billions of dollars of cash incentives and a new investment tax credit to increase domestic manufacturing capacity in our industry. In December 2023, we reached a Preliminary Memorandum of Terms with the U.S. Department of Commerce for $162 million in CHIPS Act grants for two of our U.S. wafer fabrication facilities. These preliminary terms are subject to a comprehensive due diligence process and continued negotiation and review and there can be no assurance that the grants will receive final approval. If we do receive a CHIPS Act grant, the restrictions and operational requirements that are imposed on CHIPS Act grant recipients could add complexity to our operations and increase our costs. We expect to receive the cash benefit associated with the investment tax credit for qualifying capital expenditures in future periods and expect to apply for other incentives provided by the legislation; however, there can be no assurance that we will receive any such other incentives, what the amount and timing of any incentive we receive will be, as to which other companies will receive incentives and whether the legislation will have a positive or negative impact on our competitive position.

Financing Activities

Net cash used in financing activities was $2.09 billion in the nine months ended December 31, 2023 compared to $2.49 billion in the nine months ended December 31, 2022. Significant transactions affecting our net financing cash flows included:

•in the first nine months of fiscal 2024, $839.2 million of cash used to pay down certain principal of our debt, including our 2015 Senior Convertible Debt, our 2017 Senior Convertible Debt, our 2017 Junior Convertible Debt, our 4.333% 2023 Notes, our 2.670% 2023 Notes, and our Revolving Credit Facility, partially funded by proceeds from borrowings on our 2025 Term Loan Facility, and proceeds from the issuance of our Commercial Paper, and

•in the first nine months of fiscal 2023, $1.32 billion of cash used to pay down certain principal of our debt, including our 2015 Senior Convertible Debt, our 2017 Senior Convertible Debt, our 2017 Junior Convertible Debt, and our Revolving Credit Facility, and

•in the first nine months of fiscal 2024 and fiscal 2023, we paid cash dividends to our stockholders of $669.0 million and $499.4 million, respectively, and

34

•in the first nine months of fiscal 2024 and fiscal 2023, we repurchased shares of our common stock for $594.7 million and $671.9 million, respectively.

In August 2023, our amended and restated Credit Agreement, dated as of December 16, 2021, was amended by the first incremental term loan amendment, dated as of August 31, 2023. Pursuant to this amendment, we borrowed an aggregate principal amount of $750.0 million under the new 2025 Term Loan Facility bearing interest at the Adjusted Term SOFR Rate, plus a margin of 1.125% to 1.5%, or Alternate Base Rate, plus a margin of 0.125% to 0.5%, with a maturity date of August 31, 2025. The interest rate margins are determined based on our credit ratings. In September 2023, we established a Commercial paper program under which we may issue short-term unsecured promissory notes up to a maximum principal amount outstanding at any time of $2.75 billion with a maturity of up to 397 days from the date of issue. The Commercial Paper will be sold from time to time at a discount from par or alternatively, will be sold at par and bear interest rates that will vary based on market conditions and the time of issuance. The outstanding Commercial Paper balance will reduce the amounts that would otherwise be available to borrow under our Revolving Credit Facility. As of December 31, 2023, the principal amount of our outstanding indebtedness was $5.71 billion. At December 31, 2023, we had no outstanding borrowings under the Revolving Credit Facility compared to $100.0 million at March 31, 2023. At December 31, 2023, we had $647.0 million in outstanding principal amount of Commercial Paper.

Capital Returns

In November 2021, our Board of Directors authorized the repurchase of up to $4.00 billion of our common stock in the open market or in privately negotiated transactions. In the first nine months of fiscal 2024, we repurchased approximately 7.4 million shares of our common stock for $594.7 million under this authorization. In the first nine months of fiscal 2023, we repurchased approximately 9.6 million shares of our common stock for $671.9 million under this authorization. As of December 31, 2023, approximately $2.03 billion remained available for repurchases under the program. As of December 31, 2023, we held approximately 37.4 million shares as treasury shares. Our current intent is to regularly repurchase shares of our common stock over time based on our cash generation, leverage metrics, and market conditions.

In October 2002, we announced that our Board of Directors had approved and instituted a quarterly cash dividend on our common stock.  To date, our cumulative dividend payments have totaled approximately $6.41 billion. A quarterly cash dividend of $0.439 per share was paid on December 6, 2023 in the aggregate amount of $237.4 million. A quarterly dividend of $0.450 per share was declared on February 1, 2024 and will be paid on March 8, 2024 to stockholders of record as of February 23, 2024. We expect the aggregate cash dividend for the March 2024 quarter to be approximately $243.0 million. Our Board is free to change our dividend practices at any time and to increase or decrease the dividend paid, or not to pay a dividend on our common stock on the basis of our results of operations, financial condition, cash requirements and future prospects, and other factors deemed relevant by our Board.  Our current intent is to increase our quarterly cash dividends depending upon market conditions, our results of operations, and potential changes in tax laws.

We believe that our existing sources of liquidity combined with cash generated from operations, borrowings under our Revolving Credit Facility and our 2025 Term Loan Facility, and proceeds from issuance of our Commercial Paper will be sufficient to meet our currently anticipated cash requirements for at least the next 12 months. Our long-term liquidity requirements primarily arise from working capital requirements, interest and principal repayments related to our outstanding indebtedness, capital expenditures, cash dividends, share repurchases, and income tax payments. For additional information regarding our cash requirements see "Note 10. Commitments and Contingencies", "Note 6. Debt" and "Note 11. Income Taxes" to our condensed consolidated financial statements. The semiconductor industry is capital intensive and in order to remain competitive, we must constantly evaluate the need to make significant investments in capital equipment for both production and research and development and to expand our existing facilities or potentially construct new facilities.  We may increase our borrowings under our Revolving Credit Facility or our Commercial Paper program or seek additional equity or debt financing from time to time to refinance our existing debt, maintain or expand our wafer fabrication and product assembly and test facilities, for cash dividends, for share repurchases or for acquisitions or other purposes.  The timing and amount of any such financing requirements will depend on a number of factors, including the maturity dates of our existing debt, our level of dividend payments, changes in tax laws and regulations regarding the repatriation of offshore cash, demand for our products, changes in industry conditions, product mix, competitive factors and our ability to identify suitable acquisition candidates.  We plan to refinance certain of our existing notes as they mature and we may from time to time seek to refinance certain of our other outstanding debt or Convertible Debt through issuances of new notes or convertible debt, term loans, Commercial Paper, tender offers, exchange transactions or open market repurchases. Such issuances, tender offers or exchanges or purchases, if any, will depend on prevailing market conditions, our ability to negotiate acceptable terms, our liquidity position and other factors. There can be no assurance that any financing will be available on acceptable terms due to uncertainties resulting from rising interest rates, higher inflation, economic uncertainty, instability in the banking sector, the COVID-19 pandemic, or other factors, and any additional equity financing would result in incremental ownership

35

dilution to our existing stockholders. We are also pursuing incentives under the CHIPS Act to increase our domestic manufacturing capacity; however, there can be no assurance that we will receive any such incentives or what the amount and timing of any incentive we receive will be.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

As of December 31, 2023, our current and long-term debt totaled $5.71 billion. We have no interest rate exposure to rate changes on our fixed rate debt, which totaled $4.96 billion as of December 31, 2023. We have interest rate exposure with respect to the $750.0 million of our variable interest rate debt outstanding under our 2025 Term Loan Facility, as of December 31, 2023. A 50-basis point increase in interest rates would increase our expected annual interest expense for the next 12 months by approximately $3.8 million. We intend to finance the repayment of a portion of our fixed rate debt maturing within the next 12 months using available borrowings under our Revolving Credit Facility, new fixed rate notes, term loans, Commercial Paper or other instruments at which point, changes in interest rates will have a more significant impact on our interest expense if we refinance such fixed rate debt with variable rate debt. For additional information, refer to "Note 6. Debt" for a summary of our debt obligations by maturity date.

Inflation Risk

Inflation has not had a material adverse impact on our operating results in recent periods. However, if our costs were to continue to become subject to significant inflationary pressures, we may not be able to continue to offset such higher costs through price increases which could adversely impact our operating results.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Quarterly Report on Form 10-Q, as required by paragraph (b) of Rule 13a-15 or Rule 15d-15 under the Exchange Act, we evaluated under the supervision of our Chief Executive Officer and our Chief Financial Officer, the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) of the Exchange Act).  Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures were effective to ensure that information we are required to disclose in reports that we file or submit under the Exchange Act (i) is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms, and (ii) is accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.  Our disclosure controls and procedures are designed to provide reasonable assurance that such information is accumulated and communicated to our management.  Our disclosure controls and procedures include components of our internal control over financial reporting.  Management's assessment of the effectiveness of our internal control over financial reporting is expressed at the level of reasonable assurance because a control system, no matter how well designed and operated, can provide only reasonable, but not absolute, assurance that the control system's objectives will be met.

Changes in Internal Control over Financial Reporting

During the three months ended December 31, 2023, there was no change in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Rule 13a-15 or Rule 15d-15 of the Exchange Act that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Risks Related to Our Business, Operations, and Industry

Our operating results are impacted by global economic conditions and may fluctuate in the future due to a number of factors that could reduce our net sales and profitability.

Our operating results are affected by a wide variety of factors that could reduce our net sales and profitability, many of which are beyond our control. Some of the factors that may affect our operating results include:

•general economic, industry, public health or political conditions in the U.S. or internationally, including uncertain economic conditions in U.S., China and Europe, increases in interest rates, high inflation or instability in the banking sector;

•the level of order cancellations or push-outs due to uncertain economic conditions or other factors;

•disruptions in our business, our supply chain or our customers' businesses due to public health concerns (including viral outbreaks such as COVID-19), cybersecurity incidents, terrorist activity, armed conflict, war (including military conflict in the Middle East and Russia's invasion of Ukraine), worldwide oil prices and supply, fires, natural disasters or disruptions in the transportation system;

•changes in demand or market acceptance of our products and products of our customers, and market fluctuations in the industries into which such products are sold;

•levels of inventories held by our customers and the customers of our distributors;

•availability of raw materials including rare earth minerals, supplies and equipment due to supply chain constraints or other factors;

•constrained availability from other electronic suppliers impacting our customers' ability to ship their products, which in turn may adversely impact our sales to those customers;

•fluctuations in our mix of product sales;

•announcements of other significant acquisitions by us or our competitors;

•costs and outcomes of any current or future tax audits or any litigation, investigation or claims involving intellectual property, our acquisitions, customers or other issues; and

•property damage or other losses, whether or not covered by insurance.

Period-to-period comparisons of our operating results are not necessarily meaningful and you should not rely upon any such comparisons as indications of our future performance. In future periods, our operating results may fall below our public guidance or the expectations of public market analysts and investors, which would likely have a negative effect on the price of

38

our common stock. Uncertain global economic and public health conditions, such as the COVID-19 pandemic, have caused and may in the future cause our operating results to fluctuate significantly and make comparisons between periods less meaningful.

Our operating results may be adversely impacted by the financial viability and performance of our licensees, customers, distributors, or suppliers.

We regularly review the financial viability and performance of our licensees, customers, distributors and suppliers. Any downturn in global or regional economic conditions, as a result of rising interest rates, high inflation, instability in the banking sector, the enactment of broad sanctions by the U.S. or other countries against Russia or China, the COVID-19 pandemic, industry work stoppages or other factors, may adversely impact their financial viability. The financial decline of a large licensee, customer, reseller or distributor, an important supplier, or a group thereof, could have an adverse impact on our operating results and could result in our inability to collect our accounts receivable balances, higher allowances for credit losses, and higher operating costs as a percentage of net sales. Also, these parties may not comply with their contractual commitments, or may interpret them differently than we do, which could lead to termination of their performance with little or no notice to us, which could limit our ability to mitigate our exposure. If one of our counterparties becomes insolvent, files for bankruptcy, has business leverage, or favorable contractual terms, then our ability to recover any losses suffered as a result of that counterparty's cessation of performance may be limited by their liquidity, the applicable laws, or their willingness to negotiate a resolution. In the event of such default or cessation of performance, we could incur significant losses, which could have a material adverse effect on our business, results of operations, or financial condition.

We have various arrangements with financial institutions for our cash deposits, and other banking activities, that subject us to risk if such institutions were to experience financial or regulatory difficulties. As a result, we may experience losses on our holdings of cash and cash equivalents due to failures of financial institutions or other related parties.

We may lose sales if suppliers of raw materials, components or equipment fail to meet our or our customers' needs, increase prices, are impacted by increases in tariffs, or such raw materials, components or equipment become restricted or unavailable.

Our manufacturing operations require raw and processed materials and equipment that must meet exacting standards.  We generally have multiple sources for these supplies, but there may be a limited number of suppliers capable of meeting our standards.  We have experienced supply shortages from time to time in the past, and on occasion our suppliers have told us they need more time to fill our orders, that they cannot fill certain orders, that they will no longer support certain equipment with updates or parts, or that they are increasing prices. In particular, in fiscal 2023 and in fiscal 2022, we experienced increased prices at certain suppliers for certain materials required for production purposes. However, we believe that the pricing environment has now stabilized. An interruption of any materials or equipment sources, or the lack of supplier support for a particular piece of equipment, could harm our business. The supplies necessary for our business could become more difficult to obtain as worldwide use of semiconductors increases, or due to supply chain disruptions, trade restrictions or political instability. Additionally, consolidation in our supply chain due to mergers and acquisitions may reduce the number of suppliers or change our relationships with them. Also, the reduced availability of necessary labor, the application of sanctions, trade restrictions or tariffs by the U.S. or other countries or the impact of the COVID-19 pandemic, may adversely impact the industry supply chain. For example, in 2019, the U.S. government increased tariffs on U.S. imports with China as their country of origin. Likewise, the China government increased tariffs on China imports with U.S. as their country of origin. We have taken steps to attempt to mitigate the costs of these tariffs on our business. Although these increases in tariffs did not significantly increase the operating costs of our business, they did, however, adversely impact demand for our products during fiscal 2020 and fiscal 2019. The additional tariffs imposed on components or equipment that we or our suppliers source from China will increase our costs and could have an adverse impact on our operating results in future periods. We may also incur increases in manufacturing costs in mitigating the impact of tariffs on our operations. This could also impair our sourcing flexibility.

Our customers may also be adversely affected by these same issues. The labor, supplies and equipment necessary for their businesses could become more difficult to obtain for various reasons not limited to business interruptions of suppliers, reduced availability of labor, consolidation in their supply chain, or sanctions, trade restrictions or tariffs or the impact of the COVID-19 pandemic that impair sourcing flexibility or increase costs. If our customers are not able to produce their products, then their need for our products will decrease. Such interruptions of our customers’ businesses could harm our business.

We do not, nor have we historically, purchased significant amounts of equipment from Russia, Belarus, or Ukraine. However, the semiconductor industry, and purchasers of semiconductors, use raw materials that are sourced from these regions, such as neon, palladium, cesium, rubidium, and nickel. If we, or our direct or indirect customers, are unable to obtain

39

the requisite raw materials or components needed to manufacture products, our ability to manufacture products, or demand for our products, may be adversely impacted. This could have a material adverse effect on our business, results of operations or financial condition. While there has been an adverse impact on the world’s palladium, neon, cesium, and rubidium supply chains, at this time, our supply chains have been able to meet our needs. While sales of our products into Russia, Belarus and Ukraine and to customers that sell into these countries, have been negatively impacted by the Russian invasion of Ukraine, at this time, we have not experienced a material impact on our business, results of operations or financial conditions. Further, because we do not support the actions of Russia against Ukraine, in March 2022 we stopped selling products to customers and distributors located in Russia and Belarus.

Additionally, certain materials are primarily available in a limited number of countries, including rare earth elements, minerals, and metals. Trade disputes, geopolitical tensions, economic circumstances, political conditions, or public health issues, such as COVID-19, may limit our ability to obtain materials or equipment. Although rare earth and other materials are generally available from multiple suppliers, China is the predominant producer of certain of these materials. If China were to restrict or stop exporting these materials, our suppliers' ability to obtain such supply may be constrained and we may be unable to obtain sufficient quantities, or obtain supply in a timely manner, or at a commercially reasonable cost. Constrained supply of rare earth elements, minerals, and metals may restrict our ability to manufacture certain of our products and make it difficult or impossible to compete with other semiconductor memory manufacturers who are able to obtain sufficient quantities of these materials from China or other countries.

We are dependent on wafer foundries and other contractors, as are our SuperFlash and other licensees.

We rely on outside wafer foundries for a significant portion of our wafer fabrication needs. Specifically, during the first nine months of fiscal 2024, approximately 65% of our net sales came from products that were produced at outside wafer foundries compared to 63% of our net sales in fiscal 2023. We also use several contractors for a portion of the assembly and testing of our products. Specifically, during the first nine months of fiscal 2024, approximately 42% of our assembly requirements and 29% of our test requirements were performed by third-party contractors, compared to approximately 41% and 33%, respectively, during fiscal 2023. Due to increased demand for our products, we took actions in fiscal 2023 and fiscal 2022 to increase our capacity allocation from our wafer fabrication, assembly and test subcontractors. As product demand has softened in recent quarters, we have taken actions to selectively reduce our purchases from foundries. There can be no assurance that we will be able to secure the necessary allocation of capacity from our wafer foundries and other contractors, that any such capacity will have the ability to manufacture the process technologies that we need, or that such capacity will be available on acceptable terms. Although we are continuing to expand our internal wafer fabrication, assembly and test capacity, we expect that our reliance on third-party contractors may increase over time as our business grows, and any inability to secure necessary external capacity could adversely affect our operating results.

As our manufacturing subcontractors move to more advanced process technologies over time, we may find that they do not invest in some of the trailing edge process technologies on which a large portion of our products are manufactured. If this occurs, it may limit the amounts of net sales that we can achieve or require us to make significant investments to be able to manufacture these products in our own existing facilities, at new facilities or at other foundries and assembly and testing contractors. In August 2022, the U.S. government passed the CHIPS Act to provide billions of dollars of cash incentives and a new investment tax credit to increase domestic manufacturing capacity in our industry. We expect to receive the cash benefit associated with the investment tax credit for qualifying capital expenditures in future periods and have applied for other incentives provided by the legislation; however, there can be no assurance that we will receive any such other incentives, what the amount and timing of any incentive we receive will be, as to which other companies will receive incentives and whether the legislation will have a positive or negative impact on our competitive position. If we do receive a CHIPS Act grant, the restrictions and operational requirements that are imposed on CHIPS Act grant recipients could add complexity to our operations and increase our costs.

Our use of third parties reduces our control over the subcontracted portions of our business. Our future operating results could suffer if a significant contractor were to experience production difficulties, insufficient capacity, decreased manufacturing, reduced availability of labor, assembly and test yields, or increased costs due to disruptions such as political upheaval, infrastructure disruption or pandemics. Additionally, our future operating results could suffer if our wafer foundries and other contractors increase the prices of the products and services that they provide to us. If third parties do not timely deliver products or services in accordance with our quality standards, we may be unable to qualify alternate manufacturing sources in a timely manner or on favorable terms, or at all. Additionally, these subcontractors could abandon processes that we need, or fail to adopt technologies that we desire to control costs. In such event, we could experience an interruption in production, an increase in manufacturing costs or a decline in product reliability, and our business and operating results could be adversely affected. Further, use of subcontractors increases the risks of misappropriation of our intellectual property.

40

Certain of our SuperFlash and other technology licensees rely on wafer foundries. If our licensees experienced disruption in supply at such foundries, this would reduce the revenue from our technology licensing business and would harm our operating results.

We are highly dependent on foreign sales, suppliers, and operations, which exposes us to foreign political and economic risks.

Sales to foreign customers account for a substantial portion of our net sales. During the first nine months of fiscal 2024, approximately 75% of our net sales were made to foreign customers, including 18% in China and 12% in Taiwan. During fiscal 2023, approximately 78% of our net sales were made to foreign customers, including 21% in China and 14% in Taiwan.

A strong position in the Chinese market is a key component of our global growth strategy. Although our sales in the Chinese market were very strong in calendar 2021, competition in China is intense, and China's economic growth slowed in calendar 2022 and through the first half of calendar 2023. In the first nine months of fiscal 2024, economic weakness in the Chinese market adversely impacted our sales volumes in China. As discussed above, the trade relationship between the U.S. and China remains challenging, economic conditions in China remain uncertain, and we are unable to predict whether such uncertainty will continue or worsen in future periods. Additionally, over the last several years, the impact of unpredictable COVID-19 related lockdowns and the adverse impact of the rapid transmission of COVID-19 when lockdowns in China were lifted has adversely impacted Chinese customers and the supply chain. Further, increasing investment in the semiconductor industry by the Chinese government and various state-owned of affiliated entities are intended to advance China's stated national policy objectives. The Chinese government may restrict us from participating in the China market, or may prevent us from competing effectively with Chinese companies. Weakening of foreign markets has resulted in lower demand for our products, which has adversely impacted our revenue in recent quarters and, if such conditions continue, it could have a material adverse effect on our business, results of operations or financial conditions.

We purchase a substantial portion of our raw materials and equipment from foreign suppliers. Please see the risks related to access to raw materials, components, or equipment on page 39. In addition, we own product assembly and testing facilities, and finished goods warehouses near Bangkok, Thailand, which has experienced periods of political instability and severe flooding in the past. There can be no assurance that any future flooding or political instability in Thailand would not have a material adverse impact on our operations. We have a test facility in Calamba, Philippines. We use foundries and other foreign contractors for a significant portion of our assembly and testing and wafer fabrication requirements.

Our reliance on foreign operations, foreign suppliers, maintenance of substantially all of our finished goods inventory at foreign locations and significant foreign sales exposes us to foreign political and economic risks, including, but not limited to:

•economic uncertainty in the worldwide markets served by us;

•political instability, including changes in relations between China and Taiwan which could disrupt the operations of our Taiwan-based third-party wafer foundries, and subcontractors;

•social and economic instability due to public health concerns, wars, or other factors;

•trade restrictions and changes in tariffs;

•supply chain disruptions or delays;

•potentially adverse tax consequences;

•import and export license requirements and restrictions;

•changes in laws related to taxes, trade, environmental, health and safety, technical standards, climate change, and consumer protection;

•restrictions on the transfer of funds, including currency controls in China, which could negatively affect the amount and timing of certain customer payments, and as a results our cash flows;

•currency fluctuations and foreign exchange regulations;

•difficulties in staffing and managing international operations;

•employment regulations;

•disruptions due to cybersecurity incidents;

•disruptions in international transport or delivery;

•public health conditions (including viral outbreaks such as COVID-19); and

•difficulties in collecting receivables and longer payment cycles.

If any of these risks occur or are worse than we anticipate, our sales could decrease and our operating results could suffer, we could face an increase in the cost of components, production delays, business interruptions, delays in obtaining export licenses, or denials of such licenses, tariffs and other restrictions, longer payment cycles, increased taxes, restrictions on the repatriation of funds and the burdens of complying with a variety of foreign laws, any of which could ultimately have a

41

material adverse effect on our business. Further changes in trade policy, tariffs, additional taxes, or restrictions on supplies, equipment, and raw materials including rare earth minerals, may limit our ability to produce products, increase our selling and/or manufacturing costs, decrease margins, reduce the competitiveness of our products, or inhibit our ability to sell products or purchase necessary equipment and supplies, which could have a material adverse effect on our business, results of operations, or financial conditions.

We depend on orders that are received and shipped in the same quarter and have limited visibility to product shipments other than orders placed under our LTSAs.

Our net sales in any given quarter depend upon a combination of shipments from backlog, and orders that are both received and shipped in the same quarter, which we call turns orders. We measure turns orders at the beginning of a quarter based on the orders needed to meet the shipment targets that we set entering the quarter. Historically, our ability to respond quickly to customer orders has been part of our competitive strategy, resulting in customers placing orders with relatively short delivery schedules. Shorter lead times generally mean that turns orders as a percentage of our business are relatively high in any particular quarter and reduce our visibility on future shipments. Turns orders correlate to overall semiconductor industry conditions and product lead times. Although our backlog had been strong in prior periods due to favorable business conditions and the impact of our Preferred Supply Program and our LTSAs, the business conditions that led us to implement the Preferred Supply Program had changed and, as a result, on February 1, 2024, we discontinued the Preferred Supply Program for new orders. This change in our Preferred Supply Program does not impact our LTSAs. With the cancellation of the Preferred Supply Program, turns orders are once again key to our ability to meet our business objectives. Because turns orders can be difficult to predict, especially in times of economic volatility where customers may change order levels within the quarter, varying levels of turns orders make it more difficult to forecast net sales. The level of turns orders has in the past and may in the future decrease in periods where customers are holding excess inventory of our products. Our customers may have increased their order levels in previous periods to help ensure they have sufficient inventory of our products to meet their needs, or they may have been unable to sell their products at their forecasted levels which would reduce our level of turns orders. As a significant portion of our products are manufactured at foundries, foundry lead times may affect our ability to satisfy certain turns orders. If we do not achieve a sufficient level of turns orders in a particular quarter relative to our revenue targets or effectively manage our production based on changes in order forecasts, our revenue and operating results will likely suffer.

In February 2021, we announced our Preferred Supply Program and, starting in the first quarter of calendar 2022, we began entering into LTSAs, which offer our customers the ability to receive prioritized capacity. To participate in the original Preferred Supply Program, customers were expected to place 12 months of orders, which could not be cancelled or rescheduled by the customer except in the event of price increases. In August 2023, we modified our Preferred Supply Program to allow orders for six months of continuous backlog, and those orders could be cancelled or rescheduled if our planned delivery date was greater than six months from the request date. The capacity priority under the Preferred Supply Program began for shipments in July 2021, and will end upon delivery of orders that were placed under the Preferred Supply Program prior to February 1, 2024. The Preferred Supply Program and the LTSAs are not a guarantee of supply; however, they were designed to provide the highest priority for those orders which are under these programs, and the capacity priority was on a first-come, first-served basis until the available capacity was booked. A significant portion of our backlog was booked under these programs while the programs were in effect. There can be no assurance that these programs will continue to be successful or that they will provide the benefits we expect to our business. For example, in recent periods, we have accommodated requests by customers to push-out certain orders to help them manage inventory levels and, in some cases, to help other customers that are experiencing supply shortages. However, in the event that we decide to not accommodate a request to push out orders and customers under these programs still attempt to cancel or reschedule orders, or refuse shipment, we may have to take legal or other action to enforce the terms of the programs, and any such actions could result in damage to our customer relationships or cause us to incur significant costs. We may be unable to recover damages from customers that default under these programs. Additionally, these programs have resulted in some customers holding excess inventory of our products and thus decreased their need to place new orders, including turns orders, in recent periods.

Intense competition in the markets we serve may lead to pricing pressures, reduced sales or reduced market share.

The semiconductor industry is intensely competitive and faces price erosion and rapid technological change. We compete with major domestic and international semiconductor companies, many of which have greater market recognition and substantially greater financial, technical, marketing, distribution and other resources than we do. In addition, some governments, such as China, may provide, or have provided and may continue to provide, significant assistance financial or otherwise, to some of our competitors, or to new entrants, and may intervene in support of national industries and/or competitors, including to try to disrupt the U.S. semiconductor industry. The semiconductor industry has experienced significant consolidation in recent years which has resulted in several of our competitors becoming much larger in terms of

42

revenue, product offerings and scale. We may be unable to compete successfully in the future, which could harm our business. Our ability to compete successfully depends on a number of factors, including, but not limited to:

•changes in demand in the markets that we serve and the overall rate of growth or contraction of such markets, including but not limited to the automotive, personal computing and consumer electronics markets;

•our ability to obtain adequate foundry and assembly and test capacity and supplies at acceptable prices;

•our ability to ramp production and increase capacity as needed, at our wafer fabrication and assembly and test facilities;

•the quality, performance, reliability, features, ease of use, pricing and diversity of our products;

•our success in designing and manufacturing new products including those implementing new technologies;

•the rate at which customers incorporate our products into their applications and the success of such applications;

•the rate at which the markets that we serve redesign and change their own products;

•product introductions by our competitors;

•the number, nature and success of our competitors in a given market;

•our ability to protect our products and processes by effective utilization of intellectual property rights;

•our ability to address the needs of our customers; and

•general market and economic conditions.

Historically, average selling prices in the semiconductor industry decrease over the life of a product.  The average selling prices of our mixed-signal microcontroller, FPGA products, and proprietary products in our analog product line have remained relatively constant over time, while average selling prices of our memory and non-proprietary products in our analog product line have declined over time. The overall average selling price of our products is affected by these trends; however, variations in our product and geographic mix of sales can cause wider fluctuations in our overall average selling price in any given period.

We have experienced, and may experience in the future, modest pricing declines in certain of our proprietary product lines, primarily due to competitive conditions. In the past, we have moderated average selling price declines in many of our proprietary product lines by introducing new products with more features and higher prices. However, we may not be able to do so in the future. We have experienced in the past, and may experience in the future, competitive pricing pressures on our memory and non-proprietary products in our analog product line. In fiscal 2023 and fiscal 2022, we experienced cost increases which we were able to pass on to our customers. However, in the future, we may be unable to maintain average selling prices due to increased pricing pressure, including as a result of actions taken by foreign governments such as China to favor companies located in their own country, which could adversely impact our operating results.

We, and our competitors, seek to expand production capacity, increase wafer output, improve yields, and reduce die size, which could result in significant increases in worldwide supply and downward pressure on prices. Increases in worldwide supply of semiconductor products, if not accompanied by commensurate increases in demand, could lead to declines in average selling prices for our products, and could materially adversely affect our business, results of operations, or financial condition.

Our operating results will suffer if we ineffectively utilize our manufacturing capacity or fail to maintain manufacturing yields.

Integrated circuit manufacturing processes are complex and sensitive to many factors, including contaminants in the manufacturing environment or materials used, the performance of our personnel and equipment, and other quality issues. As is typical in the industry, we have from time to time experienced lower than anticipated manufacturing yields. Our operating results will suffer if we are unable to maintain yields at or above approximately the current levels. This could include delays in the recognition of revenue, loss of revenue, and penalties for failure to meet shipment deadlines. Our operating results are adversely affected when we operate below normal capacity. In the first nine months of fiscal 2024 and in fiscal 2023, we operated at or above normal capacity levels.

We may not be able to achieve expected returns from our planned capacity expansions.

In fiscal 2023 we announced our intent to expand our production capacity in the U.S. In particular, we have continued our multi-year $800 million capacity expansion plan at Fab 4 in Gresham, Oregon and we plan to invest $880 million to expand our SiC and silicon production capacity, including the production of 8-inch wafers at Fab 5 in Colorado Springs, Colorado.

These expansion projects subject us to a number of risks, including the following:

•availability of necessary funding, which may include external sources;

•ability to realize expected grants, investment tax credits, and other government incentives, including through the

43

CHIPS Act and foreign, state, and local grants;

•increases to our cost structure until new production is ramped to adequate scale;

•sufficient customer demand to utilize our increased capacity;

•slowing macroeconomic business conditions;

•growth in our inventories;

•ability to timely ramp production in a cost-effective manner;

•potential changes in laws or provisions of grants, investment tax credits, and other government incentives;

•availability of labor, services, equipment, and construction materials;

•ability to complete construction as scheduled, and within budget; and

•availability of the necessary workforce to support the expanded capacity.

Investments in capital expenditures for our capacity expansion projects may not generate expected returns, or cash flows. Significant judgement is required to determine which capital investments will result in optimal returns, and we could invest in projects that are ultimately less profitable than those projects we do not select. Delays in commencement, completion and ramping of expanded production facilities, or failure to optimize our investment choices, or increased costs could significantly adversely impact our ability to realize expected returns on our capital expenditures. Changes in laws or rulemaking in jurisdictions where we have planned expansion may cause us to reconsider the location or size of such expansion plans. For example, a recently adopted rule in Colorado (GEMM Phase 2) requires companies to significantly reduce greenhouse gas emissions in a short timeframe. We are evaluating our ability to comply with this rule. Because we have contractual obligations to certain customers to assess the impact that manufacturing process changes may have on the products that we provide to such customers, even with the installation of costly equipment we may be unable to meet the timelines on greenhouse gas reduction required by the state of Colorado. With regard to GEMM Phase 2, we are still evaluating what impact the rule will have on our expansion plans in Colorado. Further adverse impacts to our construction projects could negatively impact our ability to reduce costs or meet customer demand. If we do receive government incentives through the CHIPS Act, or through foreign, state, and local grants, the restrictions and operational requirements that are associated with such grants could add complexity to our operations and increase our costs. With regard to the CHIPS Act, we have signed a non-binding Preliminary Memorandum of Terms to receive a grant under the CHIPS Act for modernization and expansion of our Colorado Springs, Colorado facility and expansion of our Gresham, Oregon facilities. These preliminary terms are subject to a comprehensive due diligence process and continued negotiation and review. Our failure to conclude definitive agreements for any reason and receive final awards could create a negative perception or reputational concern with respect to us and our business. Any of the above factors could have a material adverse effect on our business, results of operations or financial condition.

Our operating results are impacted by seasonality and wide fluctuations of supply and demand in the industry.

The semiconductor industry is characterized by seasonality and wide fluctuations of supply and demand.  Historically, since a significant portion of our revenue is from international sales and consumer markets, our business generates stronger revenues in the first half and comparatively weaker revenues in the second half of our fiscal year. However, broad fluctuations in our business, changes in semiconductor industry and global economic conditions (including the impact of strong demand in the industry, public health conditions or trade tensions) and our acquisition activity (including our acquisition of Microsemi) have had and can have a more significant impact on our results than seasonality. In periods when broad fluctuations, changes in business conditions or acquisitions occur, it is difficult to assess the impact of seasonality on our business. The semiconductor industry has had significant economic downturns, characterized by diminished product demand and production over-capacity. We have sought to reduce our exposure to this industry cyclicality by selling proprietary products, that cannot be quickly replaced, to a geographically diverse customer base across a broad range of market segments. However, we have experienced substantial period-to-period fluctuations in operating results and expect, in the future, to experience period-to-period fluctuations in operating results due to general industry or economic conditions. In this regard, in recent months many of our customers felt the effects of slowing economic activity and increasing business uncertainty and customer requests to push-out or cancel backlog increased in the fourth quarter of fiscal 2023 and in the first nine months of fiscal 2024 and adversely impacted our revenue in recent periods. Consistent with the slowing macroeconomic environment, and the growth in our inventory, we have paused most of our factory expansion actions and reduced our planned capital investments through fiscal 2025. We are unable to predict the timing or impact of any such slowdown on our business.

Our business is dependent on distributors to service our end customers.

Sales to distributors accounted for approximately 48% of our net sales in the first nine months of fiscal 2024 and approximately 47% of our net sales in fiscal 2023. With the exception of certain orders placed under our original Preferred Supply Program (which has been discontinued for new orders effective February 1, 2024) and LTSAs, we do not have long-

44

term purchase agreements with our distributors, and we and our distributors may each terminate our relationship with little or no advance notice.

Future adverse conditions in the U.S. or global economies and labor markets or credit markets could materially impact distributor operations. Any deterioration in the financial condition, or disruption in the operations of our distributors, could adversely impact the flow of our products to our end customers and adversely impact our results of operation. In addition, during an industry or economic downturn, there may be an oversupply and decrease in demand for our products, which could reduce our net sales in a given period, increase order push-outs, increase inventory returns, and cause us to carry elevated levels of inventory. For example, in recent periods, we have accommodated requests by customers to push-out certain orders to help them manage inventory levels and, in some cases, to help other customers that are experiencing supply shortages. As a result of the foregoing, we may incur charges in connection with obsolete or excess inventory, or we may not fully recover our costs, which would reduce our gross margins. Violations of the Foreign Corrupt Practices Act, export controls and sanction laws, or similar laws, by our distributors could have a material adverse impact on our business.

Our success depends on our ability to introduce new products on a timely basis.

Our future operating results depend on our ability to develop and timely introduce new products that compete effectively on the basis of price and performance and which address customer requirements. The success of our new product introductions depends on various factors, including, but not limited to:

•effective new product selection;

•timely completion and introduction of new product designs;

•availability of skilled employees;

•procurement of licenses for intellectual property rights from third parties under commercially reasonable terms, including those that may be needed to offer interoperability between our products and third-party products;

•implementation of appropriate technical standards developed by standard setting organizations;

•timely filing and protection of intellectual property rights for new product designs;

•availability of development and support tools and collateral literature that make complex new products easy for engineers to understand and use; and

•market acceptance of our customers' end products.

Because our products are complex, we have experienced delays from time to time in completing new product development. New products may not receive or maintain substantial market acceptance.  We may be unable to timely design, develop and introduce competitive products, which could adversely impact our future operating results.

Our success also depends upon our ability to develop and implement new design and process technologies. Semiconductor design and process technologies are subject to rapid technological change and require significant R&D expenditures. We and others in the industry have, from time to time, experienced difficulties in transitioning to advanced process technologies and have suffered reduced manufacturing yields or delays in product deliveries. Our future operating results could be adversely affected if any transition to future process technologies is substantially delayed or inefficiently implemented.

Business interruptions to our operations or those of our key vendors, licensees or customers could harm our business.

Operations at any of our facilities, at the facilities of any of our wafer fabrication or assembly and test subcontractors, or at any of our significant vendors, licensees or customers may be disrupted due to public health concerns (including outbreaks such as COVID-19), work stoppages or reduction in available labor, power loss, insufficient water, cyber-attacks, computer network compromises, incidents of terrorism or security risk, political instability, governmental actions, telecommunications, transportation or other infrastructure failure, radioactive contamination, adverse changes in climate, or fires, earthquakes, floods, droughts, volcanic eruptions or other natural disasters. We have taken steps to mitigate the impact of some of these events should they occur; however, we cannot be certain that we will avoid a significant impact on our business in the event of a business interruption. For example, in the first three months of fiscal 2023 and in fiscal 2022, COVID-19 related restrictions adversely impacted our manufacturing operations in the U.S., Philippines and Thailand along with our subcontractors' manufacturing operations in Malaysia, Taiwan and China. Similar challenges arose for our logistics service providers, which adversely impacted their ability to ship product to our customers. The pandemic could adversely impact our business in future periods if the impact of COVID-19 again becomes severe in one or more of our key markets such as China or in areas where our suppliers or manufacturing operations are located. In the future, local governments could require us to reduce production or cease operations at any of our facilities, and we could experience constraints in fulfilling customer orders.

45

Additionally, operations at our customers and licensees may be disrupted for a number of reasons. In April and May 2020, we received a greater number of order cancellations and requests by our customers to reschedule deliveries to future dates. Some customers requested order cancellations within our firm order window and claimed applicability of force majeure clauses due to the impact of COVID-19. Likewise, if our licensees are unable to manufacture and ship products incorporating our technology, or if there is a decrease in product demand due to a business disruption, our royalty revenue may decline.

Also, Thailand has experienced periods of severe flooding in recent years. While our facilities in Thailand have continued to operate normally, there can be no assurance that future flooding in Thailand would not have a material adverse impact on our operations. If operations at any of our facilities, or our subcontractors' facilities are interrupted, we may not be able to timely shift production to other facilities, and we may need to spend significant amounts to repair or replace our facilities and equipment.  Business interruptions would likely cause delays in shipments of products to our customers, and alternate sources for production may be unavailable on acceptable terms. This could result in reduced revenues, cancellation of orders, or loss of customers. Although we maintain business interruption insurance, such insurance will likely not compensate us for any losses or damages, and business interruptions could significantly harm our business. For more information on adverse climate change see our risk "Climate change regulations and sustained adverse climate change pose risks that could harm our results of operations" on page 57.

Our technology licensing business exposes us to various risks.

Our technology licensing business is based on our SuperFlash and other technologies. The success of our licensing business depends on the continued market acceptance of these technologies and on our ability to further develop such technologies, to introduce new technologies, and to enforce our license terms. To be successful, any such technology must be able to be repeatably implemented by licensees, provide satisfactory yield rates, address licensee and customer requirements, and perform competitively. The success of our technology licensing business depends on various other factors, including, but not limited to:

•proper identification of licensee requirements;

•timely development and introduction of new or enhanced technology;

•our ability to protect and enforce our intellectual property rights for our licensed technology, and enforce the terms of our licenses;

•our ability to limit our liability and indemnification obligations to licensees;

•availability of development and support services to assist licensees in their design and manufacture of products;

•availability of foundry licensees with sufficient capacity to support OEM production; and

•market acceptance of our customers' end products.

Because our licensed technologies are complex, there may be delays from time to time in developing and enhancing such technologies. There can be no assurance that our existing or any enhanced or new technology will achieve or maintain substantial market acceptance. Our licensees may experience disruptions in production or reduced production levels which would adversely affect the revenue that we receive. Our technology license agreements generally include a clause that indemnifies the licensee against liability and damages (including legal defense costs) arising from certain intellectual property matters. We could be exposed to substantial liability for claims or damages related to intellectual property matters or indemnification claims. We have a program to audit the royalty payments made by our licensees to help ensure that the payments are in accordance with the terms of the applicable license agreements. From time to time, we or our licensees have contested the amount of royalty payments and related claims have resulted and could result in significant legal fees and require significant attention from our management. These issues may adversely impact the success of our licensing business and adversely affect our future operating results.

Reliance on sales into governmental projects, and compliance with associated regulations, could have a material adverse effect on our results of operations.

As a result of our Microsemi acquisition, in May 2018, a significant portion of our sales are from or are derived from government agencies or customers who sell to U.S. government agencies.  Such sales are subject to uncertainties regarding governmental spending levels, spending priorities, regulatory and policy changes.  Future sales into U.S. government projects are subject to uncertain government appropriations and national defense policies and priorities, including the budgetary process, changes in the timing and spending priorities, the impact of any past or future government shutdowns, contract terminations or renegotiations, future sequestrations, changes in regulations that we must comply with to be eligible to accept new contracts, such as the Cybersecurity Maturity Model Certification requirements, or the impact of the COVID-19 pandemic.  For example, in fiscal 2022, as a result of the COVID-19 pandemic, we experienced suspensions and stop work orders for some of our subcontracts. Additionally, the amendment to the U.S. National Defense Authorization Act (NDAA)

46

was signed into law on December 23, 2022, and its provisions go into effect in December 2027. The NDAA amendment prohibits U.S. government agencies from buying semiconductor products or services manufactured by SMIC, YMTC, CXMT and any other entity that the U.S. government determines is owned, controlled, or connected to the government of a foreign country of concern (Prohibited Companies). Some of our products are manufactured at SMIC, and some of our suppliers buy products manufactured at YMTC. If we are unable to alternately source or manufacture certain of our products, or discontinue use of products from Prohibited Companies, if any, when the NDAA amendment goes into effect in December 2027, this could adversely impact our sales to U.S. government agencies and their prime customers. Although such actions have not yet had a material adverse impact on our business, there can be no assurance as to the future costs or implications of such actions. Sales into government projects are also subject to uncertainties related to monetary, regulatory, tax and trade policies implemented by current or future administrations or by the U.S. Congress.

In the past, Microsemi experienced delays and reductions in appropriations on programs that included its products. For example, in 2018 there were two federal government shutdowns, and such a shutdown was averted in 2023. Further delays, reductions in or terminations of government contracts or subcontracts, including those caused by any past or future shutdown of the U.S. federal government, could materially and adversely affect our operating results. If, in the future, the U.S. government fails to complete its annual budget process, provide for a continuing resolution to fund government operations or increase the federal debt limit, another federal government shutdown may occur, during which we may experience further delays, reductions in or terminations of government contracts or subcontracts, which could materially and adversely affect our operating results. While we generally function as a subcontractor in these type of transactions, further changes in U.S. government procurement regulations and practices, particularly surrounding initiatives to reduce costs or increase compliance obligations (such as the Cybersecurity Maturity Model Certification), may adversely impact the contracting environment, our ability to hire and retain employees, and our operating results.

The U.S. government and its contractors may terminate their contracts with us at any time. Uncertainty in government spending and termination of contracts for government related projects could have a material adverse impact on the revenue from our government related business.  Our contracts with U.S. governmental agencies or prime customers require us to comply with the contract terms, and governmental regulations, particularly for our facilities, systems and personnel that service such customers.  To be awarded new contracts, we may be required to meet certain levels of the Cybersecurity Maturity Model Certification that we may not meet, or choose to meet. Complying with these regulations, including audit requirements, requires that we devote significant resources to such matters in terms of training, personnel, information technology and facilities.  Any failure to comply with these requirements may result in fines and penalties, or loss of current or future business, that may materially and adversely affect our operating results.

From time to time we receive grants from governments, agencies and research organizations, or enter into tax arrangements. If we are unable to comply with the terms of those grants or arrangements, we may not be able to receive or recognize benefits or we may be required to repay benefits, recognize related charges, or could be required to implement certain limitations on our business, which would adversely affect our operating results and financial position.

From time to time, we have received, and may in the future receive, economic incentive grants, tax benefits, and allowances from national, state and local governments, agencies and research organizations targeted at increasing employment, production or investment at specific locations. Tax arrangements and subsidy grant agreements typically contain economic incentive, headcount, capital and research and development expenditures and other covenants that must be met to receive and retain benefits, and these programs can be subjected to periodic review by the relevant governments. The CHIPS Act and its associated regulations, for example, may contain certain restrictions on grant recipient technology licensing activities and the expansion of certain facilities. Compliance with these restrictions could add complexity to our operations and increase our costs. In addition, noncompliance with the conditions of the grants or arrangements could result in our forfeiture of all or a portion of any future amounts to be received, as well as the repayment of all or a portion of amounts received to date. We may be unable to obtain future incentives to continue to fund a portion of our capital expenditures and operating costs, without which our cost structure would be adversely impacted. Further, any decrease in amounts received could have a material adverse effect on our business, results of operations, or financial condition.

We may not fully realize the anticipated benefits of our completed or future acquisitions or divestitures.

We have acquired, and expect in the future to acquire, additional businesses that we believe will complement or augment our existing businesses. In May 2018, we acquired Microsemi, which was our largest and most complex acquisition ever. Integration of our acquisitions is complex and may be costly and time consuming and include unanticipated issues, expenses and liabilities. We may not successfully or profitably integrate, operate, maintain and manage any newly acquired operations or employees. We may not be able to maintain uniform standards, procedures and policies. We may not realize the expected synergies and cost savings from the integration. There may be increased risk due to integrating financial

47

reporting and internal control systems. It may be difficult to develop, manufacture and market the products of a newly acquired company, or grow the business at the rate we anticipate. Following an acquisition, we may not achieve the revenue or net income levels that justify the acquisition. We may suffer loss of key employees, customers and strategic partners of acquired companies and it may be difficult to implement our corporate culture at acquired companies. We have been and may in the future be subject to claims from terminated employees, stockholders of Microchip or the acquired companies and other third parties related to the transaction. In particular, in connection with our Microsemi and Atmel acquisitions, we became involved with third-party claims, litigation, governmental investigations and disputes related to such businesses and transactions. See "Note 10. Commitments and Contingencies" to our condensed consolidated financial statements for information regarding such matters which are still pending. Acquisitions may also result in charges (such as acquisition-related expenses, write-offs, restructuring charges, or future impairment of goodwill), contingent liabilities, adverse tax consequences, additional share-based compensation expense and other charges that adversely affect our operating results. To fund our acquisition of Microsemi, we used a significant portion of our cash balances and incurred approximately $8.10 billion of additional debt. We may fund future acquisitions of new businesses or strategic alliances by utilizing cash, borrowings under our Revolving Credit Facility, issuing Commercial Paper, raising debt, issuing shares of our common stock, or other mechanisms.

Further, if we decide to divest assets or a business, it may be difficult to find or complete divestiture opportunities or alternative exit strategies, which may include site closures, timely or on acceptable terms. These circumstances could delay the achievement of our strategic objectives or cause us to incur additional expenses with respect to the desired divestiture, or the price or terms of the divestiture may be less favorable than we had anticipated. Even following a divestiture or other exit strategy, we may have certain continuing obligations to former employees, customers, vendors, landlords or other third parties. We may also have continuing liabilities related to former employees, assets or businesses. Such obligations may have a material adverse impact on our results of operations and financial condition.

In addition to acquisitions, we have in the past, and expect in the future, to enter into joint development agreements or other strategic relationships with other companies. These transactions are subject to a number of risks similar to those we face with our acquisitions including our ability to realize the expected benefits of any such transaction, to successfully market and sell products resulting from such transactions or to successfully integrate any technology developed through such transactions.

As a result of our acquisition activity, including our acquisition of Microsemi in May 2018, our goodwill and intangible assets increased significantly and we may in the future incur impairments to goodwill or intangible assets.

When we acquire a business, a substantial portion of the purchase price of the acquisition is allocated to goodwill and other identifiable intangible assets. The amount of the purchase price which is allocated to goodwill is determined by the excess of the purchase price over the net identifiable assets acquired. As of December 31, 2023, we had goodwill of $6.68 billion and net intangible assets of $2.94 billion. In connection with the completion of our acquisition of Microsemi in May 2018, our goodwill and intangible assets increased significantly. We review our indefinite-lived intangible assets, including goodwill, for impairment annually in the fourth fiscal quarter or whenever events or changes in circumstances indicate that the carrying amount of those assets is more likely than not impaired.  Factors that may be considered in assessing whether goodwill or intangible assets may be impaired include a decline in our stock price or market capitalization, reduced estimates of future cash flows and slower growth rates in our industry.  Our valuation methodology for assessing impairment requires management to make judgments and assumptions based on experience and to rely heavily on projections of future operating performance.  Because we operate in highly competitive environments, projections of our future operating results and cash flows may vary significantly from our actual results.  No goodwill impairment charges were recorded in the first nine months of fiscal 2024 or in fiscal 2023. There were no material impairment charges to intangible assets in the first nine months of fiscal 2024. If in future periods, we determine that our goodwill or intangible assets are impaired, we will be required to write down these assets which would have a negative effect on our condensed consolidated financial statements.

If we fail to maintain proper and effective internal control and remediate any future control deficiencies, our ability to produce accurate and timely financial statements could be impaired, which could harm our operating results, our ability to operate our business and our reputation with investors.

We have in the past identified a material weakness in our internal controls related to accounting for income taxes and we also identified a material weakness in our internal controls related to IT system access. Although such material weaknesses were remediated in fiscal 2020, there can be no assurance that similar control issues will not be identified in the future. If we cannot remediate future material weaknesses or significant deficiencies in a timely manner, or if we identify additional control deficiencies that individually or together constitute significant deficiencies or material weaknesses, our ability to accurately record, process, and report financial information and our ability to prepare financial statements within required time periods, could be adversely affected. Failure to maintain effective internal controls could result in violations of applicable securities laws, stock exchange listing requirements, and the covenants under our debt agreements, subject us to litigation and investigations, negatively affect investor confidence in our financial statements, and adversely impact our stock price and our ability to access capital markets.

Ensuring that we have adequate internal financial and accounting controls and procedures so that we can produce accurate financial statements on a timely basis is a costly and time-consuming effort that needs to be re-evaluated frequently. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with U.S. GAAP. We are required to comply with Section 404 of the Sarbanes-Oxley Act of 2002 which requires an annual management assessment of the effectiveness of our internal control over financial reporting and a report by our independent auditors. In addition to the identified material weaknesses related to accounting for income taxes and to IT system access, which were remediated as of March 31, 2020, we have from time to time identified other significant deficiencies. If we fail to remediate any future material weaknesses or significant deficiencies or to maintain proper and effective internal control over financial reporting in the future, our ability to produce accurate and timely financial statements could be impaired, which could harm our operating results, harm our ability to operate our business and reduce the trading price of our stock.

Customer demands for us to implement business practices that are more stringent than legal requirements may reduce our revenue opportunities or cause us to incur higher costs.

Some of our customers require that we implement practices that are more stringent than those required by applicable laws with respect to labor requirements, the materials contained in our products, energy efficiency, environmental impact or other items. To comply with such requirements, we also require our suppliers to adopt such practices. Our suppliers may in the future refuse to implement these practices, or may charge us more for complying with them. If certain of our suppliers refuse to implement the practices, we may be forced to source from alternate suppliers. The cost to implement such practices may cause us to incur higher costs and reduce our profitability, and if we do not implement such practices, such customers may disqualify us as a supplier, resulting in decreased revenue opportunities. Developing, enforcing, and auditing customer-requested practices at our own sites and in our supply chain will increase our costs and may require more personnel.

We must attract and retain qualified personnel to be successful, and competition for qualified personnel has intensified.

We must attract and retain qualified personnel to be successful, and competition for qualified personnel had intensified in fiscal 2023 in our industry due to high demand for skilled employees. However, labor has become more available in fiscal 2024 in certain geographic markets in which we operate. Competition for available labor had intensified for a variety of reasons, including the increase in work-from home arrangements brought about by COVID-19, and the wage inflation in our industry. And while long-term labor conditions may intensify further due to the expected construction of new wafer fabrication facilities by foundries and third parties in locations near our existing facilities, in recent periods there has been greater availability of skilled employees.

Our ability to attract and retain skilled employees such as management, technical, marketing, sales, research and development, manufacturing, and operational personnel is critical to our business. We rely on a direct labor force at our manufacturing facilities. Any inability to maintain our labor force at our facilities may disrupt our operations, delay production, shipments and revenue and result in us being unable to timely satisfy customer demand, and ultimately could materially and adversely affect our business, financial condition and results of operations. Our inability to attract and retain hardware and software engineers and sales and marketing personnel, could delay the development and introduction of, and harm our ability to sell, our products. We have no employment agreements with any member of our senior management team, and it is possible that they could leave with little or no notice, which could make it more difficult for us to execute our planned business strategy. Our inability to retain, attract or motivate personnel could have a material adverse effect on our

49

business, financial condition and results of operations.

The occurrence of events for which we are self-insured, or which exceed our insurance limits, may adversely affect our profitability and liquidity.

We have insurance coverage related to many different types of risk; however, we self-insure for some potentially significant risks and obligations, because we believe that it is more cost effective for us to self-insure than to pay the high premium costs. The risks and exposures that we self-insure include, but are not limited to, employee health matters, certain property matters, product defects, cybersecurity matters, employment risks, environmental matters, political risks, and intellectual property matters. Should there be a loss or adverse judgment in an area for which we are self-insured, then our financial condition, results of operations and liquidity may be materially adversely affected.

Risks Related to Cybersecurity, Products, Privacy, Intellectual Property, and Litigation

We continue to be the target of attacks on our IT systems. Interruptions in and unauthorized access to our IT systems, attacks on or security vulnerabilities of our products, or our improper handling of data, could adversely affect our business.

We rely on the uninterrupted operation of complex IT systems and networks to operate our business.  Any improper handling of confidential data, or significant disruption to our systems or networks, including, but not limited to, new system implementations, computer viruses, security breaches, cyber-attacks, ransom-style attacks, theft or tampering, inadvertent error, facility issues, natural disasters, terrorism, war, telecommunication failures or energy blackouts, breaches of security in our customers’ or third-party providers’ networks, in third-party products we use, or in cloud-based services provided to, by, or enabled by us, could have a material adverse impact on our business, operations, supply chain, sales and operating results, result in claims of liability against us, or damage our reputation.  Such improper handling of confidential data, or system or network disruption, could result in an unauthorized release of our, our suppliers’ or our customers’ intellectual property or confidential, proprietary or sensitive information, or the release of personal data. Any release of such information or data could harm our business or competitive position, result in a loss of customer confidence, and cause us to incur significant costs to remedy the damages. In addition, any release of such information or data or the failure to properly manage the collection, handling, transfer or disposal of such information may result in regulatory inquiries or penalties, enforcement actions, remediation obligations, claims for damages, litigation, and other sanctions.

We have experienced and continue to experience verifiable attacks on our IT systems and data, including network compromises, attempts to breach our security measures and attempts to introduce malicious software into our IT systems. For example, in fiscal 2019, we learned of an ongoing compromise of our computer networks by what is believed to be sophisticated hackers. We engaged outside legal counsel and a leading forensic investigatory firm with experience in such matters. We took steps to identify malicious activity on our network including a compromise of our network and, in May 2019, we began implementing a containment plan. We routinely evaluate the effectiveness of the containment mechanisms that were implemented and continue to implement additional measures. We have analyzed the information that was compromised. We do not believe that this IT system compromise has had a material adverse effect on our business or resulted in any material damage to us. As a result of the IT system compromise, our management, including our chief executive officer and our chief financial officer, concluded that our internal controls related to IT system access were not effective resulting in a material weakness in our internal controls for fiscal 2019. Although this material weakness in our internal control was remediated in fiscal 2020, there can be no assurance that similar control issues will not be identified in future periods. Additionally, new information can develop that may impact our assessment of cyber events, including information learned as we develop and deploy mitigations.

Due to the types of products we sell and the significant amount of sales we make to government agencies or customers whose principal sales are to U.S. government agencies, we have experienced and expect to continue to experience in the future, attacks on our IT systems and data, including attempts to breach our security, network compromises and attempts to introduce malicious software into our IT systems. Also, as artificial intelligence (AI) continues to evolve, cyber-attackers could use AI to develop malicious code, sophisticated phishing attempts, and convincing deep fakes. A deep fake is a manipulation of our content or the voices or images of our leaders to maliciously publish false messages that appear to be authentic. Such messages may harm our reputation, which may in turn have an adverse impact on our revenue and profits, and reduce the trading price of our stock. A threat could also be introduced by our or our customers and business partners use of AI tools. The output of these tools may include threats such as introducing malicious code when AI generated source code is incorporated into products or systems. Were any future attacks to be successful, or through the unintentional introduction of security vulnerability due to AI usage, we may be unaware of the incident, its magnitude, or its effects until significant harm is done.

50

In recent years, we have regularly implemented improvements to our protective measures which include, but are not limited to, implementation of the following: firewalls, endpoint intrusion detection and response software, regular patches, log monitors, event correlation tools, network segmentation, routine backups with offsite retention of storage media, system audits, dual factor identification, data partitioning, privileged account segregation and monitoring, routine password modifications, and an enhanced information security program including training classes and phishing exercises for employees and contractors with system access, along with tabletop exercises conducted by information security personnel. As a result of the material weakness in our internal controls resulting from the IT systems compromise in fiscal 2019, we have taken remediation actions and implemented additional controls and we are continuing to take actions to attempt to address evolving threats. However, our system improvements have not been fully effective in preventing attacks on our IT systems and data, including breaches of our security measures, and there can be no assurance that any future system improvements will be effective in preventing future cyber-attacks or disruptions, a ransom-style attack, or limiting the damage from any future cyber-attacks or disruptions. Such system improvements have resulted in increased costs to us and any future improvements, attacks or disruptions could result in additional costs related to rebuilding our internal systems, defending litigation, complaints or other claims, providing notices to regulatory agencies or other third parties, responding to regulatory actions, or paying damages. Such attacks or disruptions could have a material adverse impact on our business, operations and financial results.

In addition, employees and former employees, in particular former employees who become employees of our competitors, customers, licensees, or other third parties, including state actors, have in the past and may in the future misappropriate, wrongfully use, publish or provide to our competitors, customers, licensees or other third parties, including state actors, our technology, intellectual property, or other proprietary or confidential information. This risk would be exacerbated to the extent our competitors for talent, particularly engineering talent, attempt to hire our employees. Similarly, we provide access to certain of our technology, intellectual property, and other proprietary or confidential information to our direct and indirect customers and licensees and certain of our consultants, who may wrongfully use such technology, intellectual property or information, or wrongfully disclose such technology, intellectual property or information to third parties, including our competitors or state actors.

Our products, or IP that we purchase or license from third parties for use in our products, as well as industry-standard specifications that we implement in our products, may be subject to security vulnerabilities. And, while some of our products contain encryption or security algorithms to protect third-party content or user-generated data stored on our products, these products could still be hacked or the encryption schemes could be compromised, breached, or circumvented by motivated and sophisticated attackers. Our products are being used in application areas that create new or increased cybersecurity, privacy or safety risks including applications that gather and process data, such as the cloud or Internet of Things, and automotive applications. We, our customers, and the users of our products may not promptly learn of or have the ability to fully assess the magnitude or effects of a vulnerability, including the extent, if any, to which a vulnerability has been exploited. Additionally, new information can develop that may impact our assessment of a security vulnerability, including information learned as we develop and deploy mitigations, or become aware of additional variants or evaluate the competitiveness of products.

Security vulnerabilities and any limitations of, or adverse effects resulting from, mitigation techniques can adversely affect our results of operations, financial condition, sales, customer relationships, share price, prospects, and reputation in a number of ways, any of which may be material. Adverse publicity about security vulnerabilities or mitigations could damage our reputation with customers or users and reduce demand for our products and services. These effects may be greater to the extent that competing products are not susceptible to the same vulnerabilities or if vulnerabilities can be more effectively mitigated in competing products. Moreover, third parties can release information regarding potential vulnerabilities of our products before mitigations are available. This, in turn, could lead to attempted or successful exploits of vulnerabilities, adversely affect our ability to introduce mitigations, or otherwise harm our business and reputation.

Third-party service providers, such as wafer foundries, assembly and test contractors, distributors, credit card processors, and other vendors have access to portions of our and our customers' data. In the event that these service providers do not properly safeguard the data that they hold, security breaches and loss of data could result. Any such breach or loss of data by our third-party service providers could negatively impact our business, operations and financial results, as well as our relationship with our customers.

51

Our failure to comply with federal, state, or international privacy and data protection laws and regulations may materially adversely affect our business, results of operations and financial condition.

We are subject to numerous laws and regulations in the U.S. and internationally regarding privacy and data protection such as the European Union’s (EU) General Data Protection Regulation (GDPR), the U.K. equivalent to the GDPR, the California Consumer Privacy Act, and the California Privacy Rights Act. The scope of these laws and regulations is rapidly evolving, subject to differing interpretations, and may be inconsistent among jurisdictions. Some of these laws create a broad definition of personal information, establish data privacy rights, impose data breach notification requirements, and create potentially severe statutory damages frameworks and private rights of action for certain data breaches. Some of the laws and regulations also place restrictions on our ability to collect, store, use, transmit and process personal information and other data across our business. For example, the GDPR restricts the ability of companies to transfer personal data from the European Economic Area (EEA) to the U.S. and other countries. Further, such laws and regulations have resulted and will continue to result in significantly greater compliance burdens and costs for companies such as us that have employees, customers, and operations in the EEA.

In order to comply with the GDPR, we have relied mainly on the European Commission’s Standard Contractual Clauses (SCCs), for transfers of personal information from the EEA to the U.S. or other countries. However, the Court of Justice of the EU in a July 2020 decision (Schrems II) invalidated the EU-U.S. Privacy Shield Framework, and also called for stricter conditions in the use of the SCCs. Following the Schrems II decision, certain data protection authorities in the EU have issued statements advising companies within their jurisdiction not to transfer personal data to the U.S. under the SCCs. At present, there are few, if any, viable alternatives to the SCCs. If we are unable to implement sufficient safeguards to ensure that our transfers of personal information from the EEA are lawful, we may face increased exposure to regulatory actions and substantial fines and injunctions against processing personal information from the EEA. The loss of our ability to lawfully transfer personal data out of the EEA may cause reluctance or refusal by European customers to communicate with us as they are currently, and we may be required to increase our data processing capabilities in the EEA at significant expense. Additionally, other countries outside of the EEA have passed or are considering passing laws requiring local data residency which could increase the cost and complexity of providing our products in those jurisdictions.

Furthermore, the GDPR and the U.K. equivalent of the GDPR expose us to two parallel data protection regimes in Europe, each of which potentially authorizes fines and enforcement actions for certain violations. Substantial fines may be imposed for breaches of data protection requirements, which can be up to 4% of a company’s worldwide revenue or 20 million Euros, whichever is greater. Although the U.K. data protection regime currently permits data transfers from the U.K. to the EEA and other third countries, covered by a European Commission 'adequacy decision' through the continued use of SCCs and binding corporate rules, these laws and regulations are subject to change, and any such changes could have adverse implications for our transfer of personal data from the U.K. to the EEA and other third countries.

While we plan to continue to undertake efforts to conform to current regulatory obligations and evolving best practices, such efforts may be unsuccessful or result in significant costs. We may also experience reluctance, or refusal by European or multi-national customers to continue to provide us with personal data due to the potential risk exposure of personal data transfers and the current data protection obligations imposed on them by applicable data protection laws or by certain data protection authorities. These and any other data privacy laws and their interpretations continue to develop and their uncertainty and inconsistency may increase the cost of compliance, cause compliance challenges, restrict our ability to offer products in certain locations in the same way that we have been, potentially adversely affect certain third-party service providers, or subject us to sanctions by data protection regulators, all of which could adversely affect our business, financial condition and results of operations.

We are exposed to various risks related to legal proceedings, investigations or claims.

We are currently, and in the future may be, involved in legal proceedings, investigations or claims regarding intellectual property rights, product failures, contracts, export controls and sanctions, and other matters. As is typical in the semiconductor industry, we receive notifications from third parties from time to time who believe that we owe them indemnification or other obligations related to claims made against us, our direct or indirect customers, or our licensees. These legal proceedings and claims, even if meritless, have in the past and could in the future result in unexpected and substantial costs to us. If we are unable to resolve or settle a matter, obtain necessary licenses on reasonable terms, reengineer products or processes to avoid infringement, provide a cost-effective remedy, or successfully prosecute or defend our position, we could incur uninsured liability in any of them, be required to take a charge to operations, be enjoined from selling a material portion of our products or using certain processes, suffer a reduction or elimination in the value of our inventories, incur reputational damage, and our business, financial condition or results of operations could be harmed.

52

It is also possible that from time to time we may be subject to claims related to the manufacture, performance, or use of our products. These claims may be due to injuries, economic damage, lost intellectual property, or environmental exposures related to manufacturing, a product's nonconformance to our or our customer’s specifications, changes in our manufacturing processes, security vulnerabilities, or unexpected customer system issues due to the integration of our products or insufficient design or testing by our customers. We could incur significant expenses related to such matters, including, but not limited to:

•costs related to writing off the value of our inventory of nonconforming products;

•recalling nonconforming products;

•providing support services, product replacements, or modifications to products and the defense of such claims;

•diversion of resources from other projects;

•lost revenue or a delay in the recognition of revenue due to cancellation of orders, unpaid receivables, or reimbursement of costs or damages;

•customer imposed fines or penalties for failure to meet contractual requirements; and

•a requirement to pay damages, penalties or recall costs.

Because the systems into which our products are integrated have a higher cost of goods than the products we sell, the expenses and damages we are asked to pay may be significantly higher than the revenue and profits we received. While we exclude consequential damages in our standard terms and conditions, certain of our contracts may not exclude such liabilities. Further, our ability to avoid such liabilities may be limited by law. We have liability insurance which covers certain damages arising out of product defects, but we do not expect that insurance will fully protect against such claims. Payments we may make in connection with these customer claims may adversely affect the results of our operations.

Further, we sell to customers in industries such as automotive, aerospace, defense, safety, security, and medical, where failure of the application could cause damage to property or persons. We may be subject to claims if our products, or the integration of our products, cause system failures. We will face increased exposure to claims if there are substantial increases in either the volume of our sales into these applications or the frequency of system failures integrating our products.

Our contractual relationships with our customers expose us to risks and liabilities.

With the exception of orders placed under our Preferred Supply Program and LTSAs, we do not typically enter into long-term contracts with our non-distributor customers, and therefore we cannot be certain about future order levels from our customers. When we enter into customer contracts (other than under our original Preferred Supply Program and LTSAs), the contracts are generally cancelable based on standard terms and conditions. Under our original Preferred Supply Program and LTSAs, customers may cancel contracts in the event of price increases. Preferred Supply Program orders placed during or after August 2023 can be cancelled or rescheduled if our planned delivery date is greater than six months from the request date. We discontinued our Preferred Supply Program for new orders effective February 1, 2024 because the business conditions that led us to implement the Preferred Supply Program had changed. This change does not impact our LTSAs. While we had approximately 125,000 customers, and our ten largest direct customers accounted for approximately 12% of our total revenue in the first nine months of fiscal 2024, and four of our top ten direct customers are contract manufacturers that perform manufacturing services for many customers, cancellation of customer contracts could have an adverse impact on our revenue and profits. For example, due to uncertainty related to the COVID-19 pandemic, we experienced an increase in order cancellations and requests to reschedule deliveries to future dates in the first quarter of fiscal 2021. Also, in recent months many of our customers felt the effects of slowing economic activity and increasing business uncertainty, and customer requests to push-out or cancel backlog and our accommodation of their requests increased in the fourth quarter of fiscal 2023 and in the first nine months of fiscal 2024.

Certain customer contracts differ from our standard terms of sale. For some of the markets that we sell into, such as the automotive and personal computer markets, our customers may have negotiating leverage over us as a result of their market size. For example, under certain contracts we have committed to supply products on scheduled delivery dates, or extended our obligations for liabilities such as warranties or indemnification for quality issues or intellectual property infringement. If we are unable to supply the customer as contractually required, the customer may incur additional production costs, lost revenues due to delays in their manufacturing schedule, or quality-related issues. We may be liable for costs and damages associated with customer claims, and we may be obligated to defend the customer against claims of intellectual property infringement and pay associated legal fees. While we try to minimize the number of contracts which contain such provisions, manage the risks of such liabilities, and set caps on our liability exposure, sometimes we are unable to do so. In order to win important designs, avoid losing business to competitors, maintain existing business, or be permitted to bid on new business, we have, and may in the future, have to agree to uncapped liability for such items as intellectual property infringement or product failure, or have to agree to liquidated damage provisions. This exposes us to risk of liability far exceeding the purchase price of the products sold under such contracts, the lifetime revenues we receive under such contracts, or potential consequential damages. Further, where we do not have negotiated customer contracts, our customer's order terms may

53

govern the transaction and contain terms unfavorable to us. These risks could result in a material adverse impact on our results of operations and financial condition.

Failure to adequately protect our intellectual property could result in lost revenue or market opportunities.

Our ability to obtain patents, licenses and other intellectual property rights covering our products and manufacturing processes is important for our success. To that end, we have acquired certain patents and licenses and intend to continue to seek patents on our technology and manufacturing processes. The process of seeking patent protection can be expensive, and patents may not be issued from currently pending or future applications. In addition, our existing and new patents, trademarks and copyrights that are issued may not have sufficient scope or strength to provide meaningful protection or commercial advantage to us. We may be subject to, or may initiate, interference proceedings in the U.S. Patent and Trademark Office, patent offices of a foreign country or U.S. or foreign courts, which can require significant financial resources. In addition, the laws of certain foreign countries do not protect our intellectual property rights to the same extent as the laws of the U.S. Infringement of our intellectual property rights by a third-party could result in uncompensated lost market and revenue opportunities for us. Although we continue to aggressively defend and protect our intellectual property on a worldwide basis, there can be no assurance that we will be successful.

Risks Related to Taxation, Laws and Regulations

Our reported financial results may be adversely affected by new accounting pronouncements or changes in existing accounting standards and practices.

We prepare our financial statements in conformity with U.S. GAAP. These accounting principles are subject to interpretation or changes by the FASB and the SEC. New accounting pronouncements and interpretations of accounting standards and practices have occurred in the past and are expected to occur in the future. New accounting pronouncements or a change in the interpretation of accounting standards or practices may have a significant effect on our reported financial results and may affect our reporting of transactions completed before the change is effective.

Regulatory authorities in jurisdictions into or from which we ship our products or import supplies could issue new export controls or trade sanctions, levy fines, restrict or delay our ability to export products or import supplies, or increase costs associated with the manufacture or transfer of products.

A significant portion of our sales involve export and import activities. Our U.S.-manufactured products or products based on U.S. technology or U.S. software are subject to laws and regulations that govern international trade, including but not limited to the Foreign Corrupt Practices Act, Export Administration Regulations (EAR), International Traffic in Arms Regulations and economic embargoes or trade sanctions against certain countries and parties, including those administered by the U.S. Departments of State, Commerce, and Treasury. Licenses or license exceptions are often required for the shipment of our products to certain countries. Our inability to timely obtain a license, for any reason, including a delay in license processing due to a federal government shutdown like that which occurred in 2018, or changes in government policies of approval or denial of licenses, could cause a delay in scheduled shipments which could have a material adverse impact on our revenue within the quarter of a shutdown, and in following quarters depending on the extent that license processing is delayed. Further, determination by a government that we have failed to comply with trade regulations or anti-bribery regulations can result in penalties which may include denial of export privileges, fines, penalties, and seizure of products, or loss of reputation, any of which could have a material adverse effect on our business, sales and earnings. A change in laws and regulations could restrict our ability to transfer product to previously permitted countries, customers, distributors or others. For example, in October 2022, the U.S. Commerce Department published a regulation that imposed restrictions on activities in or involving China, Hong Kong, and Macau related to advanced computing integrated circuits (ICs), advanced-node ICs, computer and other commodities that contain such ICs, certain semiconductor manufacturing items, and supercomputers. The regulation also expanded controls on transactions involving semiconductor manufacturing and semiconductor equipment manufacturing end-uses. Further, this regulation expanded the scope of foreign-produced items subject to license requirements under U.S. law and added 28 entities located in China to the U.S. Commerce Department Entity List. In November 2023, the U.S. Commerce Department added restrictions and export license requirements to end uses and product categories previously described in the October 2022 regulation. In addition, the U.S. Departments of Commerce, State, and Treasury have been adding parties to the restricted parties lists, and imposing prohibitions and export licensing requirements on transactions with them. The result is that there has been a slow-down in the processing of export license applications by the U.S. Government and an increased burden on us to conduct additional due diligence imposed by the October 2022 and November 2023 regulations, as well as by sanctions imposed on Russia for invading Ukraine. At this time, there has not been a material impact on our ability to obtain necessary licenses for exportation. A previous example occurred in fiscal 2020, when the U.S. Commerce Department effectively banned U.S. companies from selling products or transferring technology to

54

certain Chinese companies, including Huawei and their related companies worldwide. In fiscal 2020, the U.S. Federal Acquisition Regulation prohibited U.S. governmental agencies from buying equipment incorporating covered telecommunications equipment, as a substantial component or critical technology, where the technology came from certain Chinese companies. In July 2020, this was expanded to prohibit U.S. governmental agencies from entering into a contract with any company that uses covered telecommunications equipment whether or not the Chinese technology is related to the procurement. The EAR also effectively prohibits sales of items for a “military end use,” to a "military end-user," or for a "military intelligence" end-user, or end-use to certain countries, such as Belarus, Burma, Cambodia, Cuba, China, Iran, North Korea, Russia, Syria and Venezuela. Any of the foregoing changes to the regulatory requirements could adversely impact our operational costs due to the administrative impacts of complying with these regulations and may limit those with whom we conduct business. Any one or more of these sanctions, future sanctions, a change in laws or regulations, or a prohibition on shipment of our products or transfer of our technology to significant customers could have a material adverse effect on our business, financial condition and results of operations.

The U.S. and other countries have levied tariffs and taxes on certain goods, implemented trade restrictions, and introduced national security protection policies. Trade tensions between the U.S. and China, which escalated in 2018, have continued and include the U.S. increasing tariffs on Chinese origin goods and China increasing tariffs on U.S. origin goods. We took steps to mitigate the costs of these tariffs on our business by making adjustments in operations and supply. Although these tariff increases did not result in a material adverse impact on our operating costs in fiscal 2019 or fiscal 2020, they did reduce demand for our products during fiscal 2019 and fiscal 2020. Increased tariffs on our customers' products could adversely impact their sales, and increased tariffs on our products in comparison to those of our competitors could each result in lower demand for our products.

Further changes in trade or national security protection policy, tariffs, additional taxes, restrictions on exports or other trade barriers, including those taken against the U.S. in retaliation for U.S. policies, may limit our ability to obtain equipment, components or raw materials (including rare earth minerals), limit our ability to produce products, increase our selling and/or manufacturing costs, decrease margins, reduce the competitiveness of our products, reduce our ability to sell products, or reduce our ability to have mergers and acquisitions approved by governmental agencies, any of which could have a material adverse effect on our business, results of operations or financial conditions.

The outcome of future examinations of our income tax returns and existing tax disputes could have an adverse effect on our results of operations.

We are subject to examination of our U.S. and certain foreign income tax returns for fiscal 2007 and later. We regularly assess the likelihood of adverse outcomes of these examinations to determine the adequacy of our provision for income taxes and have reserved for potential adjustments that may result from current or future examinations. There can be no assurance that the final determination of any of these or any future examinations will not have an adverse effect on our effective tax rates, financial position and results of operations.

In September 2021, we received a Statutory Notice of Deficiency (2007 to 2012 Notice) from the United States Internal Revenue Service (IRS) for fiscal 2007 through fiscal 2012. The disputed amounts largely relate to transfer pricing matters. In December 2021, we filed a petition in the U.S. Tax Court challenging the 2007 to 2012 Notice. In September 2023, we received a Revenue Agent Report (RAR) from the IRS for fiscal 2013 and fiscal 2016. In October 2023, we received a Statutory Notice of Deficiency (2014 to 2015 Notice) from the IRS for fiscal 2014 and fiscal 2015. The disputed amounts for fiscal 2013 to fiscal 2016 largely relate to transfer pricing matters. In December 2023, we filed a petition in the U.S. Tax Court challenging the 2014 to 2015 Notice. In May 2023, we received a proposed income adjustment from the Malaysian Inland Revenue Board (IRB) for fiscal 2020. In December 2023, we received a Notice of Assessment from the IRB asserting the same proposed income adjustment. If the adjustment is upheld by the highest court that has jurisdiction over this matter in Malaysia, it could result in income taxes up to $360.0 million, exclusive of interest and penalties, which may result in additional material exposure. The disputed amounts largely relate to the characterization of certain assets. Depending on the outcome of the IRB audit, we may need to adjudicate this matter in Malaysia, and if we do, we may be required to pay the assessment and then, upon a series of favorable court rulings, request a refund of the amount. The timing of adjudicating this matter is uncertain but could commence in the next 12 months. The ultimate outcome of disputes of this nature is uncertain, and if the IRS and IRB were to prevail on their assertions, the assessed tax, penalties, and deficiency interest could have a material adverse impact on our financial position, results of operations or cash flows.

Exposure to greater than anticipated income tax liabilities, changes in tax rules and regulations, changes in the interpretation of tax rules and regulations, or unfavorable assessments from tax audits could affect our effective tax rates, financial condition and results of operations.

We are a U.S.-based multinational company subject to tax in many U.S. and foreign jurisdictions. Our income tax obligations could be affected by many factors, including changes to our operating structure, intercompany arrangements and tax planning strategies.

Our income tax expense is computed based on tax rates at the time of the respective financial period. Our future effective tax rates, financial condition and results from operations could be unfavorably affected by changes in the tax rates in jurisdictions where our income is earned, by changes in the tax rules and regulations or the interpretation of tax rules and regulations in the jurisdictions in which we do business or by changes in the valuation of our deferred tax assets. For example, the Organisation for Economic Co-operation and Development has been working on a Base Erosion and Profit Shifting Project and released an implementation package in December 2022, which provides a coordinated system to ensure that multinational enterprises pay a GMT. The guidelines and proposals may change aspects of the existing framework under which our tax obligations are determined in many of the countries where we do business. Similarly, the European Commission and several countries have issued proposals that would change aspects of the current tax framework under which we are taxed. These proposals include changes to the existing income tax framework, possibilities of a GMT, and proposals to change or impose new types of non-income taxes, including taxes based on a percentage of revenue. In August 2022, the U.S. government enacted the Inflation Reduction Act of 2022. The Inflation Reduction Act includes a new Corporate AMT of 15.0% on the AFSI of corporations with average AFSI exceeding $1.00 billion over a three-year period. The Corporate AMT is effective in fiscal 2024. Based on currently enacted tax laws, we do not expect the Inflation Reduction Act to have a material impact upon our tax expense, cash taxes, and effective tax rate.

Our business, financial condition and operating results may be adversely impacted by policies implemented globally by the current or future administrations.

The current administration in the U.S. and administrations in other global jurisdictions in which we operate, have indicated support for significant legislative and policy changes in areas including but not limited to tax, trade, labor, and the environment. If implemented, these changes could increase our effective tax rate, and increase our selling and/or manufacturing costs, which could have a material adverse effect on our business, results of operations or financial conditions. Changes in tax policy, trade regulations or other matters, and any uncertainty surrounding the scope or timing of such changes, could negatively impact the stock market, and reduce the trading price of our stock. For example, in February 2022, the U.S. began implementing widescale sanctions against Russia due to Russia's invasion of Ukraine. Sanctions against Belarus and certain Ukrainian regions were later implemented. Because the actions by Russia against Ukraine are in conflict with our Guiding Values, we chose to cease shipments into Russia and Belarus, and we will continue to comply with applicable U.S. sanctions regarding Ukraine. While sales of our products into these regions, and to customers that sell into these regions, have been negatively impacted, at this time, we have not experienced a material adverse impact on our revenue. Retaliatory acts by Russia in response to the sanctions could include cyber-attacks, sanctions, or other actions that could disrupt the economy. As a result of the foregoing risks or similar risks, the imposition of sanctions could have a material adverse effect on our business, results of operations or financial condition.

We are subject to stringent environmental and other regulations, which may force us to incur significant expenses and impact our operations.

We must comply with federal, state, local and foreign governmental regulations related to the use, storage, emissions, discharge and disposal of hazardous substances used in our products and manufacturing processes, or that are the result of our manufacturing operations, such as greenhouse gases. We must also comply with rules and regulations regarding limiting greenhouse gas emissions, public reporting of environmental metrics such as greenhouse gas emissions and hazardous substances, and obtain third party assurance of greenhouse gas reporting. Regulations could require us to change manufacturing processes, substitute materials which may cost more or be less available, obtain new permits and undertake other costly activities. Our failure to comply, or the failure of entities that we have acquired over time to have complied, with regulations could result in significant fines, litigation or administrative actions by regulators or others, liability for clean-up, reduction or suspension of production, cessation of operations or future liabilities. Restrictions on emissions could result in significant costs such as the need for additional equipment, higher energy costs, carbon taxes, and emission cap and trade programs. Such regulations have required us in the past, and could require us in the future, to incur significant expenses to comply with such regulations. Our failure to control the use of, or adequately restrict the discharge of, hazardous substances could not only impact the health of our employees, customers and communities in which we operate, but could also impact our ability to operate. Such failure could also restrict our ability to ship certain products to certain countries, require us to

56

modify our products, shipping materials or logistics, or require us to incur other significant costs and expenses. Environmental laws continue to expand with a focus on reducing or eliminating hazardous substances in electronic products and shipping materials. Future environmental regulations could require us to reengineer certain of our existing products and may make it more expensive for us to manufacture, sell and ship our products. For example, in Colorado, the GEMM Phase 2 requires companies operating in Colorado to significantly reduce greenhouse gas emissions in a short timeframe. We are evaluating our ability to comply with this rule as described in our risk factor regarding our planned capacity expansions. With regard to GEMM Phase 2, we are still evaluating what impact the rule will have on our expansion plans in Colorado. We may be required to limit our expansion plans in Colorado, ramp down our existing operations significantly or risk noncompliance with the rule. The magnitude of the penalties that may be imposed for non-compliance is not currently known but could include significant monetary penalties and orders to reduce or cease production.

In addition, the number and complexity of laws and customer requirements focused on the energy efficiency of electronic products, the recycling of electronic products, the reduction of chemicals used in and to manufacture electronic products, and the reduction in the amount of packing materials and the increase in the required recycling of packing materials have expanded significantly. It may be difficult for us to timely comply with these laws and we may have insufficient quantities of compliant products to meet customers' needs, thereby adversely impacting our sales and profitability. We may have to write off inventory if we hold unsaleable inventory as a result of changes to regulations. We expect these risks to continue. These requirements may increase our own costs, as well as those passed on to us by our supply chain.

Climate change regulations and sustained adverse climate change pose risks that could harm our results of operations.

Climate change regulations or voluntary actions we may have taken as part of our ESG initiatives could require us to limit emissions, change manufacturing processes, substitute materials which may cost more or be less available, fund offset projects, obtain new permits or undertake other costly activities. Failure to obtain required permits could result in fines or in a reduction, suspension or cessation of production. Restrictions on emissions could result in significant costs such as the need for additional equipment, higher energy costs, carbon taxes, and emission cap and trade programs. The cost of compliance with such regulations could restrict our manufacturing operations, increase our costs, and have an adverse effect on our operating results.

In March 2022, the SEC proposed a rule entitled Enhancement and Standardization of Climate-Related Disclosures for Investors. While the proposed rule is not yet in effect and is subject to change as a result of the SEC comment process, if it were to go in effect in its current form, we would incur significant additional costs of compliance due to the need for expanded data collection, analysis, and certification. Further, certain elements of the proposed rule, such as mandatory third-party verification of emissions, may be difficult to comply with in the proposed required timeframe as there may be an insufficient number of qualified third-party verification entities to meet demand.

In October 2023, Colorado adopted rule GEMM Phase 2 that requires companies to significantly reduce greenhouse gas emissions in a short timeframe. We are evaluating our ability to comply with this rule. Because we have contractual obligations to certain customers to assess the impact that manufacturing process changes may have on the products that we provide to such customers, even with the installation of costly equipment we may be unable to meet the timelines on greenhouse gas reduction required by the state of Colorado. With regard to GEMM Phase 2, we are still evaluating what impact the rule will have on our expansion plans in Colorado. Further, adverse impacts to our construction projects could negatively impact our ability to reduce costs or meet customer demand. Any of the above factors could have a material adverse effect on our business, results of operations, or financial condition.

Sustained adverse changes in climate could have a direct adverse economic impact on us due to the effects of extreme weather and climate events on our production facilities, our supply chain and customers. Utility shortages, higher costs of utilities, and reduced availability of water could disrupt our operations as well as those of our customers and suppliers. Certain of our operations are located in arid or tropical regions, which some experts believe may become vulnerable to more frequent fires, storms, severe floods and droughts. While our business recovery plans are intended to allow us to recover from natural disasters or other disruptive events, our plans may not protect us from all events.

Customer demands and regulations related to conflict-free minerals may force us to incur additional expenses.

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act, in August 2012, the SEC released investigation, and disclosure requirements regarding the use of "conflict" minerals mined from the Democratic Republic of Congo and adjoining countries. We filed a Form SD with the SEC regarding such matters on May 26, 2023. Other countries are considering similar regulations. If we cannot certify that our supply chain is free from the risk of irresponsible sourcing, customers and others may demand that we change the sourcing of materials used in the manufacture of our products, even if

57

the costs for compliant materials significantly increases or availability is limited.  If we change materials or suppliers, there will likely be costs associated with qualifying new suppliers and production capacity, delivery times and quality could be negatively impacted.  Our relationships with customers, suppliers and stockholders may be adversely affected if we are unable to certify that our products are free from the risk of irresponsible sourcing. We have incurred, and expect in the future to incur, additional costs associated with complying with these disclosure requirements, such as costs related to determining the source of any conflict minerals used in our products.  We may be unable to satisfy those that require that all of the components of our products be certified as conflict free in a materially different manner than advocated by the Responsible Minerals Initiative or the Dodd-Frank Wall Street Reform and Consumer Protection Act.  If we are unable to meet customer requirements, customers may disqualify us as a supplier, resulting in a permanent or temporary loss of sales to such customer or a reduction in purchases from us, and we may have to write off inventory if it cannot be sold.

In addition to concerns over “conflict” minerals mined from the Democratic Republic of Congo, our customers may require that other minerals and substances used within our supply chain be evaluated and reported on. An increase in reporting obligations will increase associated operating costs. This could have negative effects on our overall operating profits.

Failure to meet ESG expectations or standards, or achieve our corporate responsibility goals, could adversely affect our business, results of operations, financial condition, or stock price.

In recent years, there has been an increased focus on corporate responsibility matters, including greenhouse gas emissions and climate-related risks, renewable energy, water stewardship, waste management, data privacy, cybersecurity, diversity, equality and inclusion, responsible sourcing and supply chain, use of products for illegal or unethical purposes, human rights, and social responsibility. We are committed to corporate responsibility and actively manage these issues including through our guiding values and our internal policies. As an example, since we do not support the actions of Russia against Ukraine, in March 2022 we stopped selling products to customers and distributors located in Russia and Belarus. We have publicly announced certain goals, which we may refine or expand further in the future. These goals reflect our current plans and aspirations, and are not guarantees that we will be able to achieve them. For example, because we operate in an extensive, ever-changing global supply chain, an expectation of complete traceability of standard semiconductor products to every end use and prevention of product misuse and diversion is unachievable. Thus, despite our efforts, our products may be used for illegal or objectionable applications or our suppliers or representatives may engage in conduct that we do not agree with. In such events, we may suffer adverse publicity and our reputation may be harmed. Evolving stakeholder expectations, voluntary and required reporting regimes that are not harmonized and continue to change, and our efforts to manage these issues, report on them, and accomplish our goals, present numerous operational, regulatory, reputational, financial, legal, and other risks, any of which could have a material adverse impact, including on our reputation and stock price.

Such risks and uncertainties include:

•reputational harm, including damage to our relationship with customers, supplies, investors, governments, or other stakeholders;

•adverse impacts on our ability to sell and manufacture products;

•increased risk of litigation, investigations, or regulatory enforcement action;

•unfavorable ESG ratings or investor sentiment;

•diversion of resources and increased costs to control, assess, and report on ESG metrics;

•our ability to achieve our goals within announced timeframes;

•increased costs to achieve our goals;

•unforeseen operational and technological difficulties;

•access to and increased cost of capital; and

•adverse impacts on our stock price.

Any failure, or perceived failure, to meet evolving stakeholder expectations or industry standards, or achieve our corporate responsibility goals could have an adverse effect on our business, results of operations, financial condition, reputation, or stock price.

A requirement to fund our foreign pension plans could negatively affect our cash position and operating capital.

In connection with our acquisitions of Microsemi and Atmel, we assumed pension plans that cover certain French and German employees. Most of these plans are unfunded in compliance with statutory requirements, and we have no immediate intention of funding these plans. The projected benefit obligation totaled $53.9 million at March 31, 2023. Benefits are paid when amounts become due. We expect to pay approximately $1.8 million in fiscal 2024 for benefits earned.

58

Should regulations require funding of these plans in the future, it could negatively affect our cash position and operating capital.

Risks Related to Capitalization and Financial Markets

The future trading price of our common stock could be subject to wide fluctuations in response to a variety of factors.

The market price of our common stock has fluctuated significantly in the recent past and is likely to fluctuate in the future. The future trading price of our common stock could be subject to wide fluctuations in response to a variety of factors, many of which are beyond our control, including, but not limited to:

•global economic and financial uncertainty due to higher interest rates, higher inflation, instability in the banking sector, public health concerns or other factors;

•quarterly variations in our operating results or the operating results of other technology companies;

•changes in our financial guidance or our failure to meet such guidance;

•changes in analysts' estimates of our financial performance or buy/sell recommendations;

•general conditions in the semiconductor industry;

•the amount and timing of repurchases of shares of our common stock;

•our ability to realize the expected benefits of our completed or future acquisitions; and

•actual or anticipated announcements of technical innovations or new products by us or our competitors.

In addition, the stock market has recently and in the past experienced significant price and volume fluctuations that have affected the market prices for many companies and that often have been unrelated to their operating performance. These broad market fluctuations and other factors have harmed and may harm the market price of our common stock. The foregoing factors could also cause the market price of our Convertible Debt to decline or fluctuate substantially.

The amount and timing of our share repurchases may fluctuate in response to a variety of factors.

The amount, timing, and execution of repurchases of shares of our common stock may fluctuate based on the share price of our common stock, general business and market conditions, tax regulations impacting share repurchases and other factors including our operating results, level of cash flow, capital expenditures and dividend payments. Although our Board of Directors has authorized share repurchases of up to $4.00 billion, of which $2.03 billion is still available, the authorization does not obligate us to acquire any particular amount of shares. We cannot guarantee that our share repurchase authorization will be fully consummated or that it will enhance long-term stockholder value. The repurchase authorization may be suspended or discontinued at any time at our discretion and may affect the trading price of our common stock and increase volatility.

Our financial condition and results of operations could be adversely impacted if we do not effectively manage or refinance our current or future debt.

As of December 31, 2023, the principal amount of our outstanding indebtedness was $5.71 billion. As a result of our acquisition of Microsemi, we have substantially more debt than we had prior to May 2018. At December 31, 2023, we had no outstanding borrowings under our Revolving Credit Facility which provides up to $2.75 billion of revolving loan commitments that terminate in 2026, $750.0 million in outstanding borrowings under our 2025 Term Loan Facility, and $647.0 million in outstanding principal amount of our Commercial Paper. At December 31, 2023, we had $3.60 billion in aggregate principal amount of Senior Notes and $710.2 million in aggregate principal of Convertible Debt outstanding.

With respect to such balance of Senior Notes, our 0.972% 2024 Notes in the principal amount of $1.40 billion mature on February 15, 2024, and we intend to finance the repayment of such notes using available borrowings under our Revolving Credit Facility or under our Commercial Paper program. Since interest rates have increased significantly since we issued our 0.972% 2024 Notes, we expect our interest expense will increase as a result of the refinancing of such notes. Also, if we refinance such fixed rate notes with variable rate debt, changes in interest rates will have a more significant impact on our interest expense in future periods. There can be no assurance that we will be able to refinance our current or future debt on reasonable terms, if at all.

Servicing our debt requires a significant amount of cash, we may not have sufficient cash to fund payments and adverse changes in our credit ratings could increase our borrowing costs and adversely affect our ability to access the debt markets.

Our ability to make scheduled payments of principal, interest, or to refinance our indebtedness, including our outstanding Senior Notes, Convertible Debt, and Commercial Paper, depends on our future performance, which is subject to economic,

59

competitive and other factors. Our business may not continue to generate sufficient cash flow to service our debt and to fund capital expenditures, dividend payments, share repurchases or acquisitions. If we are unable to generate such cash flow, we may be required to undertake alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on onerous or highly dilutive terms. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at such time. Our senior notes and Commercial Paper are rated by certain major credit rating agencies. These credit ratings impact our cost of borrowing and our ability to access the capital markets and are based on our financial performance and financial metrics including debt levels. There is no assurance that we will maintain our current credit ratings. A downgrade of our credit rating by a major credit rating agency could result in increased borrowing costs and could adversely affect our ability to access the debt markets to refinance our existing debt or finance future debt. Our maintenance of substantial levels of debt could adversely affect our ability to take advantage of opportunities and could adversely affect our financial condition and results of operations.

Conversion of our Convertible Debt will dilute the ownership interest of our existing stockholders.

The conversion of some or all of our outstanding Convertible Debt will dilute the ownership interest of our existing stockholders to the extent we deliver common stock upon conversion of such debt. Following our irrevocable settlement election made on April 1, 2022, upon conversion, we are required to satisfy our conversion obligation with respect to such converted Convertible Debt by delivering cash equal to the principal amount of such converted Convertible Debt and cash and shares of common stock or any combination, at our option, with respect to any conversion value in excess thereof (i.e., the conversion spread). There would be no adjustment to the numerator in the net income per common share computation for the cash settled portion of the Convertible Debt as that portion of the debt instrument will always be settled in cash. The conversion spread will be included in the denominator for the computation of diluted net income per common share. Any sales in the public market of any common stock issuable upon conversion of our Convertible Debt could adversely affect prevailing market prices of our common stock. In addition, the existence of the Convertible Debt may encourage short selling by market participants because the conversion of the Convertible Debt could be used to satisfy short positions, or anticipated conversion of the Convertible Debt into shares of our common stock could depress the price of our common stock.

Fluctuations in foreign currency exchange rates could adversely impact our operating results.

We use forward currency exchange contracts in an attempt to reduce the adverse earnings impact from the effect of exchange rate fluctuations on our non-U.S. dollar net balance sheet exposures. Nevertheless, in periods when the U.S. dollar significantly fluctuates in relation to the non-U.S. currencies in which we transact business, the value of our non-U.S. dollar transactions can have an adverse effect on our results of operations and financial condition. In particular, in periods when the value of a non-U.S. currency significantly declines relative to the U.S. dollar, customers transacting in that currency may be unable to fulfill their contractual obligations or to undertake new obligations to make payments or purchase products. In periods when the U.S. dollar declines significantly relative to the British pound, Euro, Thai baht and Taiwan dollar, the operational costs in our European and Thailand subsidiaries are adversely affected. Although our business has not been materially adversely impacted by recent changes in the value of the U.S. dollar, there can be no assurance as to the future impact that any weakness or strength in the U.S. dollar will have on our business or results of operations.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

The following table sets forth our purchases of our common stock in the three months ended December 31, 2023:

Period	Total number of shares purchased	Average price paid per share(1)		Total number of shares purchased as part of publicly announced program	Approximate dollar value of shares that may yet be purchased under the program(1)(2) (in millions)

Recently Issued Accounting Pronouncements

Recently Issued Accounting Pronouncements Not Yet Adopted

In November 2023, the FASB issued ASU 2023-07-Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires public entities to disclose significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss, and an amount and description of the composition of other segment items to reconcile to segment profit or loss. The amendments in this update also expand the interim segment disclosure requirements. ASU 2023-07 is effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted with retrospective application required for all prior periods presented in the financial statements. The Company is currently evaluating the applicable disclosures.

In December 2023, the FASB issued ASU 2023-09-Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which modifies the rules on income tax disclosures to enhance the transparency and decision-usefulness of income tax disclosures, particularly in the rate reconciliation table and disclosures about income taxes paid. The amendments are intended to address investors’ requests for income tax disclosures that provide more information to help them better understand an entity’s exposure to potential changes in tax laws and the ensuing risks and opportunities and to assess income tax information that affects cash flow forecasts and capital allocation decisions. The guidance also eliminates certain existing disclosure requirements related to uncertain tax positions and unrecognized deferred tax liabilities. ASU 2023-09 is effective for public business entities for annual periods beginning after December 15, 2024 with early adoption permitted. All entities should apply the guidance prospectively but have the option to apply it retrospectively. The Company is continuing to assess the timing of adoption and the potential impacts of ASC 2023-09.

Segment Reporting [Abstract]

Segment Information

Segment Information

The Company's reportable segments are semiconductor products and technology licensing.  The Company does not allocate operating expenses, interest income, interest expense, other income or expense, or provision for or benefit from income taxes to these segments for internal reporting purposes, as the Company does not believe that allocating these expenses is beneficial in evaluating segment performance.  Additionally, the Company does not allocate assets to segments for internal reporting purposes as it does not manage its segments by such metrics.

The following tables represent net sales and gross profit for each segment for the periods presented (in millions):

	Three Months Ended December 31, 2023				Nine Months Ended December 31, 2023
	Net Sales		Gross Profit		Net Sales		Gross Profit

Total net sales	$	1,765.7	$	2,169.2	$	6,308.6	$	6,206.0

The product lines listed above are included entirely in the Company's semiconductor product segment with the exception of the other product line, which includes products from both the semiconductor product and technology licensing segments.

The following table represents the Company's net sales by customer type (in millions):

	Three Months Ended December 31,				Nine Months Ended December 31,
	2023		2022		2023		2022
Distributors	$	767.6	$	1,032.3	$	3,001.6	$	2,903.7
Direct customers	973.9		1,092.5		3,222.4		3,175.0

Total net sales	$	1,765.7	$	2,169.2	$	6,308.6	$	6,206.0

Distributors are customers that buy products with the intention of reselling them. Distributors generally have a distributor agreement with the Company to govern the terms of the relationship. Direct customers are non-distributor customers, which generally do not have a master sales agreement with the Company. The Company's direct customers primarily consist of OEMs and, to a lesser extent, contract manufacturers. Licensees are customers of the Company's technology licensing segment, which include purchasers of intellectual property and customers that have licensing agreements to use the Company's SuperFlash® embedded flash technology. All of the customer types listed in the table above are included in the Company's semiconductor product segment with the exception of licensees, which is included in the technology licensing segment.

The Company collects amounts in advance for certain of its contracts with customers. These amounts are deferred until control of the product or service is transferred to the customer at which time it is recognized as revenue. As of December 31, 2023, the Company had approximately $907.2 million of deferred revenue, of which $203.2 million is included within accrued liabilities and the remaining $704.0 million is included within other long-term liabilities on the Company's condensed consolidated balance sheet. As of March 31, 2023, the Company had approximately $757.7 million of deferred revenue in the semiconductor product segment, of which $121.4 million is included within accrued liabilities and the remaining $636.3 million is included within other long-term liabilities on the Company's condensed consolidated balance sheets. Deferred revenue represents amounts that have been invoiced in advance which are expected to be recognized as revenue in future periods. Approximately $82.5 million of deferred revenue recorded on the Company's consolidated balance sheets as of March 31, 2023, was recognized as revenue during the nine months ended December 31, 2023. This amount was immaterial for the nine months ended December 31, 2022.

Of the $907.2 million of deferred revenue as of December 31, 2023, $868.5 million is cash collected from customers under LTSAs, of which $168.6 million is included within accrued liabilities and $699.9 million is included within other long-term liabilities. Under these LTSAs, the Company receives an upfront deposit from the customer in exchange for assured supply over the contract period, which typically ranges from three to five years. If the customer does not meet the minimum purchase commitments defined in the contract, the Company may retain all, or portions of, the deposit as revenue. If the Company fails to assure supply as defined in the contract, the deposit, or portions of it, will be returned to the customer. The remaining performance obligations for the LTSAs were approximately $3.92 billion as of December 31, 2023, of which approximately 24% is expected to be recognized as net sales during the next 12 months. The amount and timing of such net sales is uncertain because it depends on the satisfaction of commitments made in the LTSAs, which may be affected by the timing and amount of orders placed by customers, contract modifications, variable consideration, sales channels, and manufacturing and supply chain conditions. Accordingly, the amount may not be indicative of net sales in future periods. The remaining $38.7 million of deferred revenue as of December 31, 2023 is related to other cash payments received from customers in advance of the Company’s performance obligations being satisfied. Most of the $38.7 million will be recognized as net sales within the next 12 months. The amount of firmly committed orders with performance obligations in excess of 12 months at the time of order is immaterial.

Diluted weighted average common shares outstanding	546.5		555.4		549.0		558.4
Basic net income per common share	$	0.78	$	1.06	$	3.23	$	2.96
Diluted net income per common share	$	0.77	$	1.04	$	3.19	$	2.93

The Company computed basic net income per common share based on the weighted average number of common shares outstanding during the period. The Company computed diluted net income per common share based on the weighted average number of common shares outstanding plus potentially dilutive common shares outstanding during the period.

Potentially dilutive common shares from employee equity incentive plans are determined by applying the treasury stock method to the assumed exercise of outstanding stock options and the assumed vesting of outstanding RSUs. Prior to conversion of its Convertible Debt, the Company will include, in the diluted net income per common share calculation, the effect of the additional shares that may be issued when the Company's common stock price exceeds the conversion price using the if-converted method. The Company's Convertible Debt has no impact on diluted net income per common share unless the average price of the Company's common stock exceeds the conversion price because the Company is required to settle the principal amount of the Convertible Debt in cash upon conversion.  

The following is the weighted average conversion price per share used in calculating the dilutive effect (see Note 6 for details on the Convertible Debt):

	Three Months Ended December 31,				Nine Months Ended December 31,
	2023		2022		2023		2022
2015 Senior Convertible Debt	$	28.95	$	29.52	$	29.10	$	29.65

2020 Senior Convertible Debt	$	91.78	$	92.74	$	92.05	$	92.91
2017 Junior Convertible Debt(1)	$	—	$	45.22	$	44.81	$	45.42

(1) The weighted average conversion price per share for the 2017 Junior Convertible Debt was prior to the settlement of the outstanding principal amount in May 2023.

Ranking of Convertible Debt - Each series of Convertible Debt is an unsecured obligation which is subordinated in right of payment to the amounts outstanding under the Company's Senior Indebtedness. The Senior Subordinated Convertible Debt is subordinated to the Senior Indebtedness; ranks senior to the Company's indebtedness that is expressly subordinated in right of payment to it; ranks equal in right of payment to any of the Company's unsubordinated indebtedness that does not provide that it is senior to the Senior Subordinated Convertible Debt; ranks junior in right of payment to any of the Company's secured and unsecured unsubordinated indebtedness to the extent of the value of the assets securing such indebtedness; and is structurally subordinated to all indebtedness and other liabilities of the Company's subsidiaries.

Summary of Conversion Features - Each series of Convertible Debt is convertible, subject to certain conditions, into cash, shares of the Company's common stock or a combination thereof, at the Company's election, at specified conversion rates (see table below), adjusted for certain events including the declaration of cash dividends. Except during the three-month period immediately preceding the maturity date of the applicable series of Convertible Debt, each series of Convertible Debt is convertible only upon the occurrence of (i) such time as the closing price of the Company's common stock exceeds the applicable conversion price (see table below) by 130% for 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter, (ii) during the 5 business day period after any 10 consecutive trading day period, or the measurement period, in which the trading price per $1,000 principal amount of notes of a given series for each trading day of the measurement period was less than 98% of the product

of the last reported sale price of the Company's common stock and the applicable conversion rate on each such trading day, or (iii) upon the occurrence of certain corporate events specified in the indenture of such series of Convertible Debt. In addition, for each series, with the exception of the 2020 Senior Convertible Debt, if at the time of conversion the applicable price of the Company's common stock exceeds the applicable conversion price at such time, the applicable conversion rate will be increased by up to an additional maximum incremental shares rate, as determined pursuant to a formula specified in the indenture for the applicable series of Convertible Debt, and as adjusted for cash dividends paid since the issuance of such series of Convertible Debt. However, in no event will the applicable conversion rate exceed the applicable maximum conversion rate specified in the indenture for the applicable series of Convertible Debt (see table below). On April 1, 2022, the Company irrevocably elected cash settlement for the principal amount of its Convertible Debt.

The following table sets forth the applicable conversion rates adjusted for dividends declared since issuance of such series of Convertible Debt and the applicable incremental share factors and maximum conversion rates as adjusted for dividends paid since the applicable issuance date:

	Dividend adjusted rates as of December 31, 2023
	Conversion Rate	Approximate Conversion Price		Incremental Share Factor	Maximum Conversion Rate
2015 Senior Convertible Debt(1)	34.5457	$	28.95	17.2746	48.3631
2017 Senior Convertible Debt(1)	22.1521	$	45.14	11.0768	31.5669
2020 Senior Convertible Debt(1)	10.8961	$	91.78	—	15.2546

(1) As of December 31, 2023, the 2020 Senior Convertible Debt was not convertible. As of December 31, 2023, the holders of each of the 2015 Senior Convertible Debt and 2017 Senior Convertible Debt have the right to convert their notes between January 1, 2024 and March 31, 2024 because the Company's common stock price has exceeded the applicable conversion price for such series by 130% for the specified period of time during the quarter ended December 31, 2023. As of December 31, 2023, the adjusted conversion rate for the 2015 Senior Convertible Debt and the 2017 Senior Convertible Debt would be increased to 46.2753 shares of common stock and 27.6841 shares of common stock, respectively, per $1,000 principal amount of notes based on the closing price of $90.18 per share of common stock to include an additional maximum incremental share rate per the terms of the applicable indenture. As of December 31, 2023, each of the 2015 Senior Convertible Debt and 2017 Senior Convertible Debt had a conversion value in excess of par of $21.4 million and $56.9 million, respectively.

With the exception of the 2020 Senior Convertible Debt, which became redeemable by the Company after November 20, 2022, the Company may not redeem any series of Convertible Debt prior to the relevant maturity date and no sinking fund is provided for any series of Convertible Debt. Under the terms of the applicable indenture, the Company may repurchase any series of Convertible Debt in the open market or through privately negotiated exchange offers. Upon the occurrence of a fundamental change, as defined in the applicable indenture of such series of Convertible Debt, holders of such series may require the Company to purchase all or a portion of their Convertible Debt for cash at a price equal to 100% of the principal amount plus any accrued and unpaid interest.

(3) The Company used borrowings under its Revolving Credit Facility to finance a portion of such settlement.

(4) The Company settled portions of its 2015 Senior Convertible Debt and 2017 Senior Convertible Debt, and the outstanding principal amount of its 2017 Junior Convertible Debt in privately negotiated transactions that are accounted for as induced conversions.

Senior Credit Facilities

In August 2023, the amended and restated Credit Agreement, dated as of December 16, 2021, was amended by the first incremental term loan amendment, dated as of August 31, 2023. Pursuant to this amendment, the Company borrowed an aggregate principal amount of $750.0 million under the new 2025 Term Loan Facility bearing interest at the Adjusted Term SOFR Rate, plus a margin of 1.125% to 1.5%, or Alternate Base Rate, plus a margin of 0.125% to 0.5%, with a maturity date of August 31, 2025. The interest rate margins are determined based on the Company's credit rating.

Commercial Paper

In September 2023, the Company established a Commercial Paper program under which the Company may issue short-term unsecured promissory notes up to a maximum principal amount outstanding at any time of $2.75 billion with a maturity of up to 397 days from the date of issue. The Company's obligations with respect to the payment of the Commercial Paper are guaranteed by certain of its subsidiaries. The Commercial Paper will be sold at a discount from par or alternatively, will be sold at par and bear interest rates that will vary based on market conditions and the time of issuance. Outstanding Commercial Paper reduces the amounts that would otherwise be available to borrow under the Company's Revolving Credit Facility. As of December 31, 2023, the Company had $647.0 million of principal amount of Commercial Paper outstanding. The weighted-average interest rate of the Company's outstanding Commercial Paper was 5.64% as of December 31, 2023.

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

Fair Value of Financial Instruments

Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants.  As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability.  As a basis for considering such assumptions, the Company utilizes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level 1-Observable inputs such as quoted prices in active markets;

Level 2-Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and

Level 3-Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

The carrying amount of cash equivalents approximates fair value because their maturity is less than three months. Management believes the carrying amount of the equity investments materially approximated fair value at December 31, 2023 based upon unobservable inputs. The fair values of these investments have been determined as Level 3 fair value measurements. The carrying amount of accounts receivable, accounts payable and accrued liabilities approximates fair value due to the short-term maturity of the amounts and are considered Level 2 in the fair value hierarchy.  

The fair value of the Company's Revolving Credit Facility, the 2025 Term Loan Facility, and the Commercial Paper, is estimated using discounted cash flow analysis, based on the Company's current incremental borrowing rates for similar types of borrowing arrangements. Based on the borrowing rates currently available to the Company for bank loans with similar terms and average maturities, the fair value of the Company's Revolving Credit Facility, the 2025 Term Loan Facility, and the Commercial Paper at December 31, 2023 approximated the carrying value excluding debt discounts and debt issuance costs and are considered Level 2 in the fair value hierarchy. The Company measures the fair value of its Convertible Debt and Senior Notes for disclosure purposes. These fair values are based on observable market prices for this debt, which is traded in less active markets and are therefore classified as a Level 2 fair value measurement.

The following table shows the carrying amounts and fair values of the Company's debt obligations (in millions):

Commitments and Contingencies

Commitments and Contingencies

Purchase Commitments

The Company's purchase commitments primarily consist of agreements for the purchase of property, plant and equipment and other goods and services including wafer purchase obligations with the Company's wafer foundries, and manufacturing supply capacity reservation commitments.

Total purchase commitments as of December 31, 2023, are as follows (in millions):

Fiscal Year Ending March 31,	Purchase Commitments
2024	$	309.8
2025	332.6
2026	233.9
2027	197.9
2028	170.3
Thereafter	197.0
Total	$	1,441.5

Indemnification Contingencies

The Company's technology license agreements generally include an indemnification clause that indemnifies the licensee against liability and damages (including legal defense costs) arising from any claims of patent, copyright, trademark or trade secret infringement by the Company's proprietary technology.  The terms of these indemnification provisions approximate the terms of the outgoing technology license agreements, which are typically perpetual unless terminated by either party for breach. The possible amount of future payments the Company could be required to make based on agreements that specify indemnification limits, if such indemnifications were required on all of these agreements, is approximately $189.0 million. There are some licensing agreements in place that do not specify indemnification limits. As of December 31, 2023, the Company had not recorded any liabilities related to these indemnification obligations and the Company believes that any amounts that it may be required to pay under these agreements in the future will not have a material adverse effect on its financial position, cash flows or results of operations.

Warranty Costs and Product Liabilities

The Company accrues for known product-related claims if a loss is probable and can be reasonably estimated. During the periods presented, there have been no material accruals or payments regarding product warranty or product liability. Historically, the Company has experienced a low rate of payments on product claims. Although the Company cannot predict the likelihood or amount of any future claims, the Company does not believe these claims will have a material adverse effect on its financial condition, results of operations or liquidity.

Legal Matters

In the ordinary course of the Company's business, it is exposed to various legal actions as a result of contracts, product liability, customer claims, pricing or royalty disputes with customers and licensees, governmental investigations and other matters. The Company is involved in a limited number of these legal actions, both as plaintiff and defendant, with respect to the foregoing types of matters. Consequently, the Company could incur uninsured liability in any of these legal actions.  The Company also periodically receives notifications from various third parties alleging infringement of patents or other intellectual property rights, or from customers requesting reimbursement for various costs. With respect to pending legal actions to which the Company is a party and other claims, although the outcomes are generally not determinable, the Company believes that the ultimate resolution of these matters will not have a material adverse effect on its financial position, cash flows or results of operations. Litigation, governmental investigations and disputes relating to the semiconductor industry are not uncommon, and the Company is, from time to time, subject to such litigation, governmental investigations and disputes.  As a result, no assurances can be given with respect to the extent or outcome of any such litigation, governmental investigations or disputes in the future.

The Company accrues for claims and contingencies when losses become probable and reasonably estimable. As of the end of each applicable reporting period, the Company reviews each of its matters and, where it is probable that a liability has been or will be incurred, the Company accrues for all probable and reasonably estimable losses. Where the Company can

reasonably estimate a range of losses it may incur regarding such a matter, the Company records an accrual for the amount within the range that constitutes its best estimate. If the Company can reasonably estimate a range but no amount within the range appears to be a better estimate than any other, the Company uses the amount that is the low end of such range. As of December 31, 2023, the Company's estimate of the aggregate potential liability for legal matters that is possible but not probable is approximately $150.0 million in excess of amounts accrued.

As a result of its acquisition of Atmel, which closed April 4, 2016, the Company became involved with the following legal matter:

Individual Labor Actions by former LFR Employees. In June 2010, Atmel Rousset sold its wafer manufacturing business in Rousset, France to LFoundry GmbH (LF), the German parent of LFoundry Rousset (LFR). LFR then leased the Atmel Rousset facility to conduct the manufacture of wafers. More than three years later, LFR became insolvent and later liquidated. In the wake of LFR's insolvency and liquidation, over 500 former employees of LFR filed individual labor actions against Atmel Rousset in a French labor court, and in 2019 a French labor court dismissed all of the employees’ claims against Atmel Rousset. In 2020, the Plaintiffs filed appeals with the Court of Appeals requesting reconsideration of the earlier dismissals. In December 2022, the Court of Appeals dismissed these appeals and held that there had been no co-employment of the plaintiffs by Atmel Rousset and LFoundry Rousset. However, in 2017 these same claims were filed by this same group of employees in a regional court in France against Microchip Technology Incorporated and Atmel Corporation. The Company, and the other defendant entities, believe that each of these actions is entirely devoid of merit, and, further, that any assertion by any of the Claimants of a co-employment relationship with any of these entities is based substantially on the same specious arguments that the Paris Commercial Court summarily rejected in 2014 in related proceedings. The defendant entities therefore intend to defend vigorously against each of these claims. Additionally, complaints have been filed in a regional court in France on behalf of the same group of employees against Microchip Technology Rousset, Atmel Switzerland Sarl, Atmel Corporation and Microchip Technology Incorporated alleging that the sale of the Atmel Rousset production unit to LF was fraudulent and should be voided. These claims are specious and the defendant entities therefore intend to defend vigorously against these claims.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

The Company accounts for income taxes in accordance with ASC 740. The provision for income taxes is attributable to U.S. federal, state, and foreign income taxes. The Company’s effective tax rate for the interim period ended December 31, 2023 is 19.03% and is based on an estimated annual effective tax rate including the tax effect of items required to be recorded discretely in the interim periods in which those items occur. A comparison of the Company’s effective tax rates for the nine months ended December 31, 2023 and December 31, 2022 is not meaningful due to the amount of pre-tax income, and income tax expense recorded during the prior period.

The Company's effective tax rate is different than the statutory rates in the U.S. due to foreign income taxed at different rates than the U.S., changes in uncertain tax benefit positions, changes to valuation allowances, generation of tax credits, and the impact of Global Intangible Low Tax Income (GILTI) in the U.S. In addition, the Company has numerous tax holidays it receives related to its Thailand manufacturing operations based on its investment in property, plant and equipment in Thailand. The Company's tax holiday periods in Thailand expire at various times in the future, however, the Company actively seeks to obtain new tax holidays. The material components of foreign income taxed at a rate lower than the U.S. are earnings accrued in Thailand, Malta, and Ireland.

The Company files U.S. federal, U.S. state, and foreign income tax returns.  For U.S. federal, and in general for U.S. state tax returns, the fiscal 2007 and later tax years remain open for examination by tax authorities.  For foreign tax returns, the Company is generally no longer subject to income tax examinations for years prior to fiscal 2007.

In September 2021, the Company received a Statutory Notice of Deficiency (2007 to 2012 Notice) from the United States Internal Revenue Service (IRS) for fiscal 2007 through fiscal 2012. The disputed amounts largely relate to transfer pricing matters. In December 2021, the Company filed a petition in the U.S. Tax Court challenging the 2007 to 2012 Notice.

In September 2023, the Company received a Revenue Agent Report (RAR) from the IRS for fiscal 2013 and fiscal 2016. In October 2023, the Company received a Statutory Notice of Deficiency (2014 to 2015 Notice) from the IRS for fiscal 2014 and fiscal 2015. The disputed amounts for fiscal 2013 to fiscal 2016 largely relate to transfer pricing matters. In December 2023, the Company filed a petition in the U.S. Tax Court challenging the 2014 to 2015 Notice.

In May 2023, the Company received a proposed income adjustment from the Malaysian Inland Revenue Board (IRB) for fiscal 2020. In December 2023, the Company received a Notice of Assessment from the IRB asserting the same proposed income adjustment. If the adjustment is upheld by the highest court that has jurisdiction over this matter in Malaysia, it could result in income taxes up to $360.0 million, exclusive of interest and penalties, which may result in additional material exposure. The disputed amounts largely relate to the characterization of certain assets. Depending on the outcome of the IRB audit, the Company may need to adjudicate this matter in Malaysia, and if the Company does, the Company may be required to pay the assessment and then, upon a series of favorable court rulings, request a refund of the amount. The timing of adjudicating this matter is uncertain but could commence in the next 12 months.

The Company firmly believes that the assessments described above are without merit and plan to pursue all available administrative and judicial remedies necessary to resolve these matters. The Company intends to vigorously defend the positions and the Company is confident in its ability to prevail on the merits. The Company regularly assesses the likelihood of adverse outcomes resulting from examinations such as these to determine the adequacy of the Company's tax reserves. The ultimate outcome of disputes of this nature is uncertain, and if the IRS and IRB were to prevail on their assertions, the assessed tax, penalties, and deficiency interest could have a material adverse impact on the Company's financial position, results of operations or cash flows.

Recently Issued Accounting Pronouncements Not Yet Adopted

In November 2023, the FASB issued ASU 2023-07-Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires public entities to disclose significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss, and an amount and description of the composition of other segment items to reconcile to segment profit or loss. The amendments in this update also expand the interim segment disclosure requirements. ASU 2023-07 is effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted with retrospective application required for all prior periods presented in the financial statements. The Company is currently evaluating the applicable disclosures.

In December 2023, the FASB issued ASU 2023-09-Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which modifies the rules on income tax disclosures to enhance the transparency and decision-usefulness of income tax disclosures, particularly in the rate reconciliation table and disclosures about income taxes paid. The amendments are intended to address investors’ requests for income tax disclosures that provide more information to help them better understand an entity’s exposure to potential changes in tax laws and the ensuing risks and opportunities and to assess income tax information that affects cash flow forecasts and capital allocation decisions. The guidance also eliminates certain existing disclosure requirements related to uncertain tax positions and unrecognized deferred tax liabilities. ASU 2023-09 is effective for public business entities for annual periods beginning after December 15, 2024 with early adoption permitted. All entities should apply the guidance prospectively but have the option to apply it retrospectively. The Company is continuing to assess the timing of adoption and the potential impacts of ASC 2023-09.
