NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1.BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Unaudited Interim Financial Information—The accompanying unaudited, condensed consolidated financial statements have been prepared according to the rules and regulations of the United States (the “U.S.”) Securities and Exchange Commission (the “SEC”) and, in the opinion of management, reflect all adjustments, which include normal recurring adjustments, necessary for a fair statement of the condensed consolidated balance sheets, condensed consolidated statements of operations, comprehensive income (loss), stockholders’ equity and cash flows of MACOM Technology Solutions Holdings, Inc. (“MACOM,” the “Company,” “us,” “we” or “our”) for the periods presented. We prepare our interim financial information using the same accounting principles we use for our annual audited consolidated financial statements. Certain information and note disclosures normally included in the annual audited consolidated financial statements have been condensed or omitted in accordance with prescribed SEC rules. We believe that the disclosures made in our condensed consolidated financial statements and the accompanying notes are adequate to make the information presented not misleading.

The condensed consolidated balance sheet as of September 27, 2024 is as reported in our audited consolidated financial statements as of that date. Our accounting policies are described in the notes to our September 27, 2024 consolidated financial statements, which were included in our Annual Report on Form 10-K for our fiscal year ended September 27, 2024 filed with the SEC on November 12, 2024 (the “2024 Annual Report on Form 10-K”). We recommend that the financial statements included in this Quarterly Report on Form 10-Q be read in conjunction with the consolidated financial statements and notes included in our 2024 Annual Report on Form 10-K.

Principles of Consolidation and Basis of Presentation—The accompanying condensed consolidated financial statements include our accounts and the accounts of our majority-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

We have a 52- or 53-week fiscal year ending on the Friday closest to the last day of September. Fiscal year 2025 includes 53 weeks and fiscal year 2024 included 52 weeks. To offset the effect of holidays, for fiscal years in which there are 53 weeks, we include the extra week arising in such fiscal years in the first fiscal quarter. Our first fiscal quarter ended January 3, 2025 included 14 weeks.

Use of Estimates—The preparation of condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities during the reporting periods, the reported amounts of revenue and expenses during the reporting periods and the disclosure of contingent assets and liabilities at the date of the financial statements. On an ongoing basis, we base estimates and assumptions on historical experience, currently available information and various other factors that management believes to be reasonable under the circumstances. Actual results may differ materially from these estimates and assumptions. The accounting policies which our management believes involve the most significant application of judgment or involve complex estimation, are inventories and associated reserves; revenue reserves; business combinations; goodwill and intangible asset valuation; share-based compensation valuations and income taxes.

Property and Equipment—Property and equipment is stated at cost, less accumulated depreciation and amortization. Expenditures for maintenance and repairs are charged to expense as incurred, whereas major improvements that significantly extend the useful life of the assets are capitalized as additions to property and equipment.

As of September 28, 2024, the Company changed its accounting estimate for the expected useful lives of certain fabrication-related machinery and equipment. The Company evaluated its current asset base and reassessed the estimated useful lives of certain machinery and equipment in connection with its recent usage of older equipment, including considering the technological and physical obsolescence of such machinery and equipment. Based on our ability to re-use equipment across generations of process technologies and historical usage trends, the Company determined that the expected useful lives for certain fabrication-related machinery and equipment should be increased to ten years to reflect more closely the estimated economic lives of those assets. This change in estimate was applied prospectively effective for the first quarter of fiscal year 2025 and resulted in a decrease in depreciation expense of $0.6 million and $1.9 million for the three and nine months ended July 4, 2025, respectively, to cost of revenue. This benefit increased earnings per share by $0.01 and $0.02, for the three and nine months ended July 4, 2025, respectively.

Recent Accounting Pronouncements—Our Recent Accounting Pronouncements are described in our 2024 Annual Report on Form 10-K.

In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2024-04, Debt - Debt with Conversion and Other Options (Subtopic 470-20) Induced Conversions of Convertible Debt Instruments, which clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion. We elected to early adopt ASU 2024-04 in November 2024 and applied the amendment when assessing the accounting treatment for our debt extinguishment (discussed in Note 9 - Debt).

Pronouncements for Adoption in Subsequent Periods

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) Improvements to Reportable Segment Disclosures, which improves disclosures about a public entity’s reportable segments and addresses requests from investors and other allocators of capital for additional, more detailed information about a reportable segment’s expenses. The amendments in this update improve financial reporting by requiring disclosure of incremental segment information on an annual and interim basis for all public entities to enable investors to develop more decision-useful financial analyses. This ASU should be applied on a retrospective basis. The amendments in this update are effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. We are currently evaluating the future effect the adoption of this ASU will have on our consolidated financial statements and related disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) Improvements to Income Tax Disclosures, which requires greater disaggregation of income tax disclosures. The amendments in this update improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. Other amendments in this update improve the effectiveness and comparability of disclosures by (1) adding disclosures of pretax income (or loss) and income tax expense (or benefit) and (2) removing disclosures that no longer are considered cost beneficial or relevant. This ASU should be applied on a prospective basis, with retrospective application permitted. The guidance in this update is effective for fiscal years beginning after December 15, 2024. We are currently evaluating the future effect the adoption of this ASU will have on our consolidated financial statements and related disclosures.

In November 2024, the FASB issued ASU 2024-03, Income Statement Reporting Comprehensive Income - Expense Disaggregation Disclosures, as amended by ASU 2025-01, Income Statement Reporting Comprehensive Income - Expense Disaggregation Disclosures: Clarifying the Effective Date, which requires disclosure, in the notes to financial statements, of specified information about certain costs and expenses. The amendments in this update improve financial reporting by requiring that public business entities disclose additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods. This ASU should be applied on a prospective basis, with retrospective application permitted. The amendments in this update are effective for annual reporting periods beginning after December 15, 2026 and interim periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. We are currently evaluating the future effect the adoption of this ASU will have on our consolidated financial statements and related disclosures.

(2)Asia Pacific primarily represents Australia, India, Japan, Malaysia, Singapore, South Korea and Taiwan.

(3)No country or region represented greater than 10% of our total revenue as of the dates presented, other than the United States, China and Asia Pacific region as presented above.

Contract Balances

We record contract assets or contract liabilities depending on the timing of revenue recognition, billings and cash collections on a contract-by-contract basis. Our contract liabilities primarily relate to deferred revenue, including advanced consideration received from customers for contracts prior to the transfer of control to the customer, and, therefore, revenue is subsequently recognized upon delivery of products and services.

The following table presents the changes in contract liabilities during the nine months ended July 4, 2025 (in thousands, except percentage):


	July 4, 2025		September 27, 2024		$ Change		% Change
Contract liabilities	$	5,251	$	5,281	$	(30)	(0.6)	%

During the three and nine months ended July 4, 2025, we recognized sales of $0.3 million and $1.7 million, respectively, that were included in the contract liabilities balance as of the beginning of the period. The decrease in contract liabilities during the nine months ended July 4, 2025 was primarily related to recognition of revenue that was previously deferred for products and services invoiced prior to when certain of our customers obtained control of such products and/or services, offset by deferral of revenue for additional invoicing prior to when our customers obtain control of such products and/or services.

3. ACQUISITIONS

ENGIN-IC, Inc.—On November 5, 2024, we completed the acquisition of ENGIN-IC, Inc. (“ENGIN-IC”), a fabless semiconductor company that designs advanced gallium arsenide (“GaAs”) and gallium nitride (“GaN”) monolithic microwave integrated circuits (“MMICs”) and integrated microwave assemblies located in Plano, Texas and San Diego, California (the “ENGIN-IC Acquisition”). We acquired ENGIN-IC to further expand and strengthen our MMIC and module design capabilities. In connection with the ENGIN-IC Acquisition, we acquired all of the outstanding shares of ENGIN-IC for a total purchase price of approximately $14.4 million and was acquired with cash consideration of $12.7 million, net of cash acquired of $0.2 million, and consideration payable of $1.5 million, subject to customary purchase price adjustments. The ENGIN-IC Acquisition was accounted for as a business combination and the operations of ENGIN-IC have been included in our consolidated financial statements since the date of acquisition. We have recorded a preliminary allocation of the purchase price for ENGIN-IC, which primarily resulted in intangible assets, including acquired technology and customer relationships, of $9.7 million and goodwill of $5.0 million.

Consolidated estimated pro forma unaudited revenue and consolidated estimated pro forma net loss during the three and nine months ended July 4, 2025 and during the three and nine months ended June 28, 2024 and the actual results of operations for ENGIN-IC since the acquisition date are not material to our condensed consolidated financial statements for the periods presented.

RF Business of Wolfspeed, Inc.—On December 2, 2023, we completed the acquisition of certain assets and specified liabilities of the radio frequency (“RF”) business (the “RF Business,”) of Wolfspeed, Inc. (the “Seller”), which was accounted for as a business combination (the “RF Business Acquisition”). The RF Business includes a portfolio of GaN on Silicon Carbide products used in high-performance RF and microwave applications. In connection with the RF Business Acquisition, we assumed control of a wafer fabrication facility in Research Triangle Park, North Carolina (the “RTP Fab”) on July 25, 2025 (the “RTP Fab Transfer”). Refer to Note 18 - Subsequent Events for additional information on the RTP Fab Transfer. Prior to the RTP Fab Transfer, the Seller continued to operate the facility and supply wafer product and other fabrication services to us pursuant to various agreements entered into between the parties concurrently with the closing of the RF Business Acquisition.

The purchase price for the RF Business Acquisition consisted of $75.0 million payable in cash and 711,528 shares of our common stock, with a fair value of $57.7 million, which were issued at the closing of the RF Business Acquisition. The shares of our common stock issued in connection with the RF Business Acquisition were subject to restrictions on the sale of shares until completion of the RTP Fab Transfer. In addition, if the RTP Fab had not transferred by the fourth anniversary of the closing date of the RF Business Acquisition, the Seller would have forfeited 25% of the share consideration. We funded the cash purchase price for the RF Business Acquisition through cash-on-hand.

During the three months ended July 4, 2025 and June 28, 2024 and the nine months ended July 4, 2025, we did not incur any acquisition-related transaction costs. During the nine months ended June 28, 2024, we incurred acquisition-related transaction costs of approximately $7.4 million, which are included in selling, general and administrative expense.

We finalized the RF Business Acquisition purchase accounting during the fiscal quarter ended January 3, 2025. The following table summarizes the final purchase price (in thousands, except shares and closing share price amount):


			At Acquisition Date as Reported September 27, 2024		Measurement Period Adjustments		At Acquisition Date as Reported January 3, 2025

Cash purchase consideration			$	72,802	$	—	$	72,802
Number of shares of MACOM common stock issued at closing	711,528
Fair value of shares issued	$	81.14
Equity purchase consideration			57,733		—		57,733

Total purchase consideration			$	130,535	$	—	$	130,535

The final purchase price has been allocated as follows (in thousands):


	At Acquisition Date as Reported September 27, 2024		Measurement Period Adjustments		At Acquisition Date as Reported January 3, 2025

Current assets	$	39	$	—	$	39
Inventory	31,097		649		31,746
Property and equipment	35,415		—		35,415
Intangible assets	42,000		1,800		43,800
Prepayment for net assets associated with the RTP Fab Transfer	16,250		—		16,250
Other non-current assets	5,837		—		5,837
Goodwill	9,967		(859)		9,108
Total assets acquired	140,605		1,590		142,195
Current liabilities	6,882		1,590		8,472
Long-term liabilities	3,188		—		3,188
Total liabilities assumed	10,070		1,590		11,660
Purchase Price	$	130,535	$	—	$	130,535

Intangible assets consist of technology, a favorable contract and customer relationships with fair values of $21.0 million, $14.5 million and $8.3 million, respectively, and useful lives of 4.8 years, 2.0 years and 8.8 years, respectively. We used variations of income approaches with estimates and assumptions developed by us to determine the fair values of technology, the favorable contract and customer relationships. We valued technology by using the relief-from-royalty method, the favorable contract by using the discounted cash flow method and customer relationships by using the multi-period excess earnings method. We valued backlog using the multi-period excess earnings method and determined that the value for backlog is zero. The process for estimating the fair values of identifiable intangible assets requires the use of significant estimates and assumptions, including revenue growth rates, royalty rates, operating margin and discount rates. We used the cost and market approaches to determine the fair value of our property and equipment. We amortize definite-lived assets based on the pattern over which we expect to receive the economic benefit from these assets.

The prepayment of $16.3 million for the net assets associated with the RTP Fab Transfer, classified in Prepaid and other current assets as of July 4, 2025 in our condensed consolidated balance sheet, relates to the estimated fair value of property and equipment, inventory and liabilities that we assumed control of at the time of the RTP Fab Transfer. The cost and market approaches were used in determining the fair value of $10.4 million for property and equipment expected to transfer at the RTP Fab Transfer date. The remaining prepayment relates to inventory and liabilities, net, that we assumed control of at the time of the RTP Fab Transfer.

The RF Business has been included in our consolidated financial statements since the date of acquisition. Consolidated estimated pro forma unaudited revenue for the three and nine months ended June 28, 2024 was $190.5 million and $555.7 million, respectively. Consolidated pro forma net income for the three and nine months ended June 28, 2024 is not material to understanding our condensed consolidated financial statements due to the business combination effects from the RF Business Acquisition, primarily acquisition transaction costs. Pro forma revenue was prepared for comparative purposes only and is not indicative of what would have occurred had the acquisition actually occurred on October 1, 2022, or of the results that may occur in the future.

4. INVESTMENTS

All investments are short-term in nature and are invested in certificates of deposit, corporate bonds, commercial paper, U.S. Treasuries and agency bonds, and are classified as available-for-sale. These investments are owned directly by the Company and are segregated in brokerage custody accounts. The amortized cost, gross unrealized holding gains or losses and fair value of our available-for-sale investments by major investment type are summarized in the tables below (in thousands):


	July 4, 2025
	Amortized Cost		Gross Unrealized Holding Gains		Gross Unrealized Holding Losses		Aggregate Fair Value

Corporate bonds	487,440		1,313		(288)		488,465
Commercial paper	58,909		—		(56)		58,853

U.S. Treasuries and agency bonds	54,931		248		(17)		55,162
Total short-term investments	$	432,848	$	2,444	$	(210)	$	435,082

The contractual maturities of available-for-sale investments were as follows (in thousands):


	July 4, 2025		September 27, 2024
Less than one year	$	192,769	$	284,479
Over one year	416,991		150,603
Total available-for-sale investments	$	609,760	$	435,082

We have determined that the gross unrealized losses on available for sale securities as of July 4, 2025 and September 27, 2024 are temporary in nature and/or do not relate to credit loss, and therefore, there is no expense for credit losses recorded in our condensed consolidated statements of operations. Unrealized gains and losses on available-for-sale investments are reported as a separate component of stockholders’ equity within accumulated other comprehensive income (loss).

5. FAIR VALUE AND FINANCIAL INSTRUMENTS

We group our financial assets and liabilities measured at fair value on a recurring basis in three levels, based on the markets in which the assets and liabilities are traded, and the reliability of the assumptions used to determine fair value. These levels are:


Level 1 - Quoted prices in active markets for identical assets or liabilities.
Level 2 - Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets with insufficient volume or infrequent transactions (less active markets), or model-driven valuations in which all significant inputs are observable or can be derived principally from, or corroborated with, observable market data.
Level 3 - Fair value is derived from valuation techniques in which one or more significant inputs are unobservable, including assumptions and judgments made by us.

Assets and Liabilities Measured and Recorded at Fair Value on a Recurring Basis

We measure certain assets and liabilities at fair value on a recurring basis such as our financial instruments. There have been no transfers between Level 1, 2 or 3 assets or liabilities during the three and nine months ended July 4, 2025.

Assets and liabilities measured at fair value on a recurring basis consist of the following (in thousands):

Derivatives

We have foreign currency exposure arising from certain of our Euro and Yen denominated intercompany debt. We have entered into foreign currency exchange hedging contracts associated with this debt to partially mitigate the impact of currency rate changes. They are not designated as cash flow or fair value hedges under Accounting Standards Codification (“ASC”) 815, Derivatives and Hedging. Changes in fair value are reported in current period earnings. These gains and losses are intended to offset the gains and losses recorded on the associated intercompany debt. We do not use derivative financial instruments for trading or speculation purposes.

As of July 4, 2025 and September 27, 2024, we had $33.0 million and $34.4 million, respectively, in notional forward foreign currency contracts. As of July 4, 2025 and September 27, 2024, the fair value of derivative instruments not designated as hedges was less than $0.1 million and $0.1 million, respectively, and was presented in Accrued liabilities on the Consolidated Balance Sheets.

Less accumulated depreciation and amortization	(267,617)		(250,005)
Property and equipment, net	$	208,987	$	176,017

During the nine months ended July 4, 2025, we exercised an option to purchase manufacturing facilities that we leased in France for €1 (one Euro) and we reclassified the finance lease asset to land and buildings. This lease was acquired in May 2023 in connection with a prior year asset acquisition and was valued as part of purchase accounting using a market approach. Additionally, during the three months ended July 4, 2025, we entered into a lease that is considered a failed sale-leaseback for accounting purposes, resulting in additions to land and building, refer to Note 10 - Financing Obligation for additional information.

In August 2022, the U.S. government enacted the CHIPS and Science Act of 2022 (“CHIPS Act”), which provides funding for manufacturing grants and research investments and established a 25% investment tax credit (“ITC”) for certain qualifying investments in U.S. semiconductor manufacturing equipment. On July 4, 2025 the U.S. Congress passed a federal statute controlling tax and spending policies (the “July 4, 2025 Bill”). As part of the July 4, 2025 Bill, this ITC was increased to 35%. We account for the investment tax credit as a reduction to the carrying value of the qualifying asset and record a corresponding receivable for expected tax credits in connection with the CHIPS Act. As of each of July 4, 2025 and September 27, 2024, there was a $5.4 million reduction to the carrying amounts of the qualifying assets in the condensed consolidated balance sheet.

Depreciation and amortization expense related to property and equipment for the three and nine months ended July 4, 2025 was $7.5 million and $22.2 million, respectively. Depreciation and amortization expense related to property and equipment for the three and nine months ended June 28, 2024 was $7.9 million and $22.3 million, respectively. Accumulated amortization on finance lease assets as of July 4, 2025 and September 27, 2024 was $10.7 million and $10.2 million, respectively.

2026 Convertible Notes

On March 25, 2021, we issued 0.25% convertible senior notes due in fiscal year 2026, pursuant to an indenture dated as of such date (the “2021 Indenture”), between the Company and U.S. Bank National Association, as trustee, with an aggregate principal amount of $400.0 million (the “Initial Notes”), and on April 6, 2021, we issued an additional $50.0 million aggregate principal amount (the “Additional Notes”) (together, the “2026 Convertible Notes”). The Additional Notes were issued and sold to the initial purchaser of the Initial Notes, pursuant to the option to purchase the Additional Notes granted by the Company to the initial purchaser and have the same terms as the Initial Notes.

On December 12, 2024, we entered into separate, privately negotiated exchange and subscription agreements (the “Exchange and Subscription Agreements”) with a limited number of holders of the 2026 Convertible Notes. Under the terms of the Exchange and Subscription Agreements, the holders exchanged $288.8 million in aggregate principal amount of 2026 Convertible Notes held by them for $257.7 million of our 2029 Convertible Notes (defined below), 1,582,958 newly-issued shares of the Company’s common stock, par value $0.001 per share, issued at a fair value of $205.9 million, and $17.6 million in cash. These exchanges resulted in aggregate pre-tax debt extinguishment charges of $193.1 million. The Company also issued approximately $86.6 million in additional aggregate principal amount of the 2029 Convertible Notes in a private placement to certain investors (the “Subscription” and, together with the Exchange, the “Transactions”). The Transactions closed on December 19, 2024.

Following the closing of the Transactions, the aggregate principal balance of the 2026 Convertible Notes is $161.2 million and the terms of the 2021 Indenture are unchanged. The 2026 Convertible Notes will mature on March 15, 2026, unless earlier converted, redeemed or repurchased.

Holders of the 2026 Convertible Notes may convert their notes at their option at any time prior to the close of business on the business day immediately preceding December 15, 2025 in multiples of $1,000 principal amount, only under the following circumstances: (i) during any fiscal quarter commencing after the fiscal quarter ending on July 2, 2021 (and only during such fiscal quarter), if the last reported sale price of our common stock for at least 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 is greater than or equal to 130% of the conversion price for the notes on each applicable trading day; (ii) during the five business day period after any five consecutive trading day period (the “Measurement Period”) in which the “trading price” (as defined in the 2021 Indenture) per $1,000 principal amount of the notes for each trading day of the Measurement Period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate for the notes on each such trading day; (iii) if we call such notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the applicable redemption date; or (iv) upon the occurrence of specified corporate events described in the 2021 Indenture. On or after December 15, 2025 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their notes in multiples of $1,000 principal amount, regardless of the foregoing circumstances.

The initial conversion rate for the 2026 Convertible Notes is 12.1767 shares of common stock per $1,000 principal amount of the notes, equivalent to an initial conversion price of approximately $82.12 per share of common stock. The conversion rate will be subject to adjustment upon the occurrence of certain specified events in the 2021 Indenture.

In November 2021, we made an irrevocable election to pay cash for the aggregate principal amount of notes to be converted. Upon conversion of the 2026 Convertible Notes, we are required to pay cash up to the aggregate principal amount of the notes to be converted and pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election, in respect of the remainder, if any, of our conversion obligation in excess of the aggregate principal amount of the notes being converted (subject to, and in accordance with, the settlement provisions of the 2021 Indenture). We must notify the holders of the 2026 Convertible Notes of our settlement method for our conversion obligation in excess of the aggregate principal amount no later than December 15, 2025, for conversions occurring on or after that date. We may redeem for cash all or any portion of the notes, at our option, on or after March 20, 2024 if the last reported sale price per share of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which we provide notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest, to, but not including, the redemption date.

The 2021 Indenture does not contain any financial or operating covenants or restrictions on the payments of dividends, the making of investments, the incurrence of indebtedness or the purchase or prepayment of securities by us or any of our subsidiaries.

During the fiscal quarter ended July 4, 2025, our common stock price met the price trigger defined above, and therefore, holders of our 2026 Convertible Notes may convert their notes at their option at any time during our fourth fiscal quarter ending October 3, 2025.

For the three and nine months ended July 4, 2025, total interest expense for the 2026 Convertible Notes was $0.1 million and $0.5 million, respectively. For the three and nine months ended June 28, 2024, total interest expense for the 2026 Convertible Notes was $0.3 million and $0.8 million, respectively.

The fair value of our 2026 Convertible Notes was $281.2 million and $640.6 million as of July 4, 2025 and September 27, 2024, respectively, and was determined based on quoted prices in markets that are not active, which is considered a Level 2 valuation input.

There are no future minimum principal payments under the notes as of July 4, 2025; the full amount of $161.2 million is due on March 15, 2026. The 2026 Convertible Notes balance of $160.8 million, net of deferred financing costs, is classified as short-term debt in our condensed consolidated balance sheet.

2029 Convertible Notes

On December 19, 2024, we issued 0.00% convertible senior notes due in fiscal year 2030, pursuant to an indenture dated as of such date (the “2024 Indenture”), between the Company and U.S. Bank National Association, as trustee with an aggregate principal amount of $344.3 million (the “2029 Convertible Notes”).

Holders of the 2029 Convertible Notes may convert their notes at their option at any time prior to the close of business on the business day immediately preceding September 15, 2029 in multiples of $1,000 principal amount, only under the following circumstances: (i) during any fiscal quarter commencing after the fiscal quarter ending on April 4, 2025 (and only during such fiscal quarter), if the last reported sale price of our common stock for at least 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 calendar quarter is greater than or equal to 130% of the conversion price for the notes on each applicable trading day; (ii) during the five business day period after any five consecutive trading day period (the “Measurement Period”) in which the “trading price” (as defined in the 2024 Indenture) per $1,000 principal amount of the notes for each trading day of the Measurement Period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate for the notes on each such trading day; (iii) if we call such notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or (iv) upon the occurrence of specified corporate events described in the 2024 Indenture. On or after September 15, 2029 until the close of business on the second scheduled trading day immediately preceding the maturity date, the holders may convert their notes, in multiples of $1,000 principal amount, regardless of the foregoing circumstances.

The initial conversion rate for the Notes is 5.7463 shares of common stock (subject to adjustment as provided for in the 2024 Indenture) per $1,000 principal amount of the notes, which is equal to an initial conversion price of approximately $174.03 per share of common stock.

The 2029 Convertible Notes do not bear regular interest, and the principal amount of the notes does not accrete. The notes are senior unsecured obligations of the Company and will mature on December 15, 2029, unless earlier redeemed, repurchased or converted. Upon conversion of the 2029 Convertible Notes, we are required to pay cash up to the aggregate principal amount of the notes to be converted and pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election, in respect of the remainder, if any, of our conversion obligation in excess of the aggregate principal amount of the notes being converted (subject to, and in accordance with, the settlement provisions of the 2024 Indenture). We must notify the holders of the 2029 Convertible Notes of our settlement method for our conversion obligation in excess of the aggregate principal amount no later than September 15, 2029, for conversions occurring on or after that date. We may redeem for cash all or any portion of the notes, at our option, on or after December 20, 2027 and prior to September 15, 2029 if the last reported sale price per share of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which we provide notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest, to, but not including, the redemption date.

The 2024 Indenture does not contain any financial or operating covenants or restrictions on the payments of dividends, the making of investments, the incurrence of indebtedness or the purchase or prepayment of securities by us or any of our subsidiaries.

The fair value of our 2029 Convertible Notes was $363.8 million as of July 4, 2025 and was determined based on quoted prices in markets that are not active, which is considered a Level 2 valuation input.

There are no future minimum principal payments under the notes as of July 4, 2025; the full amount of $344.3 million is due on December 15, 2029.

10. FINANCING OBLIGATION

We are party to a power purchase agreement for the use of electric power and thermal energy producing systems at our fabrication facility in Lowell, Massachusetts. We do not own these systems; however, we control the use of the assets during operation. As of July 4, 2025 and September 27, 2024, the net book value of the systems in Property and equipment, net was $7.7 million and $8.2 million, respectively, and the corresponding liability was $9.1 million and $9.3 million, respectively, primarily classified in Financing obligation on our condensed consolidated balance sheet.

Sale-Leaseback

In connection with the RF Business Acquisition, the Seller granted MACOM a right of first offer to purchase the RTP Fab property. MACOM exercised this right and subsequently assigned it to a third-party, who completed the purchase of the property during the quarter ended July 4, 2025. Simultaneously, we entered into a 12-year lease agreement with the third-party to lease the RTP Fab property. This lease also includes two consecutive renewal options, each for a term of ten years.

The lease between MACOM and the third-party is considered a failed sale-leaseback for accounting purposes as we have the option to purchase the property during the lease term. Accordingly, we recognized the fair value of the RTP Fab property within Property and Equipment, net, allocated to land and building, and recorded a corresponding liability classified in Financing Obligation on the condensed consolidated balance sheets. The financing obligation was calculated based on future fixed lease payments over the expected term, discounted at an incremental borrowing rate of 7.4%.

The building will be depreciated over the remaining useful life. Lease payments under the agreement are recognized as interest expense and a reduction of the financing obligation over the term of the agreement. As of July 4, 2025, the net book value of the land and building in Property and equipment, net was $28.8 million and the corresponding liability was $28.6 million.

12. COMMITMENTS AND CONTINGENCIES

From time to time, we may be subject to commercial disputes, employment issues, claims by other companies in the industry that we have infringed their intellectual property rights and other similar claims and litigation. Any such claims may lead to future litigation and material damages and defense costs. We were not involved in any material pending legal proceedings during the three and nine months ended July 4, 2025.

13. STOCKHOLDERS’ EQUITY AND SHARE-BASED COMPENSATION

We have authorized 10 million shares of $0.001 par value preferred stock and 300 million shares of $0.001 par value common stock as of July 4, 2025.

Stock Plans

As of July 4, 2025, we had 3.2 million shares available for issuance under our 2021 Omnibus Incentive Plan (the “2021 Plan”), which replaced our 2012 Omnibus Incentive Plan (as amended and restated) (the “2012 Plan”), and 1.0 million shares available for issuance under our 2021 Employee Stock Purchase Plan (the “Employee Stock Purchase Plan”), which replaced our 2012 Employee Stock Purchase Plan. We have outstanding awards under the 2021 Plan and the 2012 Plan. Following the adoption of the 2021 Plan, no additional awards have been or will be made under the 2012 Plan. Under the 2021 Plan, we have the ability to issue incentive stock options (“ISOs”), non-statutory stock options (“NSOs”), stock appreciation rights (“SARs”), restricted stock awards (“RSAs”), unrestricted stock awards, stock units (including restricted stock units (“RSUs”) and performance-based restricted stock units (“PRSUs”), performance awards, cash awards, and other share-based awards to employees, directors, consultants and advisors. The ISOs and NSOs must be granted at an exercise price, and the SARs must be granted at a base value, per share of not less than 100% of the closing price of a share of our common stock on the date of grant (or, if no closing price is reported on that date, the closing price on the immediately preceding date on which a closing price was reported) (110% in the case of certain ISOs). Options granted under the 2012 Plan primarily vested based on certain market-based and performance-based criteria and generally have a term of four years to seven years. Certain of the share-based awards granted and outstanding as of July 4, 2025 are subject to accelerated vesting upon a change in control of the Company.

Incentive Stock Units

Aside from the equity plans described above, we also grant incentive stock units (“ISUs”) to certain of our international employees which typically vest over three or four years and for which the fair value is determined by our underlying stock price, which are classified as liabilities and settled in cash upon vesting.

As of July 4, 2025 and September 27, 2024, the fair value of outstanding ISUs was $5.9 million and $6.8 million, respectively, and the associated accrued compensation liability was $3.7 million and $4.6 million, respectively. During the three and nine months ended July 4, 2025, we recorded an expense for ISU awards of $1.8 million and an expense of $3.0 million, respectively. During the three and nine months ended June 28, 2024, we recorded an expense for ISU awards of $1.2 million and $2.6 million, respectively. These expenses are not included in the share-based compensation expense totals below.

Share-Based Compensation

The following table shows a summary of share-based compensation expense included in the condensed consolidated statements of operations (in thousands):


	Three Months Ended				Nine Months Ended
	July 4, 2025		June 28, 2024		July 4, 2025		June 28, 2024
Cost of revenue	$	1,728	$	1,522	$	6,376	$	4,392
Research and development	7,109		5,446		25,235		13,173
Selling, general and administrative	8,469		6,377		29,982		16,527
Total share-based compensation expense	$	17,306	$	13,345	$	61,593	$	34,092

As of July 4, 2025, the total unrecognized compensation costs related to RSUs and PRSUs was $94.3 million, which we expect to recognize over a weighted-average period of 1.9 years. As of July 4, 2025, total unrecognized compensation cost related to our Employee Stock Purchase Plan was $1.6 million.

Restricted Stock Units and Performance-Based Restricted Stock Units

A summary of RSU and PRSU activity for the nine months ended July 4, 2025 is as follows:


	Number of shares (in thousands)	Weighted- Average Grant Date Fair Value
Balance as of September 27, 2024	1,634	$	72.37
Granted	656	$	127.08
Performance-based adjustment (1)	144	$	89.82
Vested and released	(905)	$	76.16
Forfeited, canceled or expired	(109)	$	78.48
Balance as of July 4, 2025	1,420	$	96.51

(1) The amount shown represents performance adjustments for market-based performance awards. These were granted in prior fiscal years and vested during the nine months ended July 4, 2025 based on the Company’s achievement of total stockholder return.

Stock awards that vested during the nine months ended July 4, 2025 and June 28, 2024 had combined fair values of $117.6 million and $41.8 million, respectively, as of the vesting date. RSUs granted generally vest over a period of three or four years.

Market-based PRSUs

We granted 108,300 market-based PRSUs during the nine months ended July 4, 2025, at a weighted average grant date fair value of $168.47 per share. Recipients may earn between 0% and 200% of the target number of shares based on the Company’s achievement of total stockholder return in comparison to a peer group of companies in the PHLX Semiconductor Sector Index (^SOX) over a period of approximately three years. The fair value of the awards was estimated using a Monte Carlo simulation and compensation expense is recognized ratably over the service period based on the grant date fair value of the awards subject to the market condition. The expected volatility of the Company’s common stock was estimated based on the historical average volatility rate over the three-year period. The dividend yield assumption was based on historical and anticipated dividend payouts. The risk-free rate assumption was based on observed interest rates consistent with the three-year measurement period.

The weighted-average assumptions used to value the market-based PRSU awards are as follows:


	Nine Months Ended
	July 4, 2025
Weighted-average grant date stock price	$	115.69
Weighted-average stock price at the start of the performance period	$	103.09
Weighted-average risk free interest rate	4.0%
Weighted-average years to maturity	2.9
Weighted-average expected volatility rate	39.2%
Weighted-average expected dividend yield	—

Stock Options

As of each of July 4, 2025 and September 27, 2024, there were 5,000 stock options outstanding, with a weighted-average exercise price per share of $16.06. As of July 4, 2025, the weighted-average remaining contractual term was 0.34 years and the aggregate intrinsic value was $0.6 million. Aggregate intrinsic value is calculated using the difference between our closing stock price on July 4, 2025 and the exercise price of outstanding, in-the-money options. There were no options exercised during the nine months ended July 4, 2025. The total intrinsic value of options exercised during the nine months ended June 28, 2024 was $0.3 million.

14. INCOME TAXES

We are subject to income tax in the U.S. as well as other tax jurisdictions in which we conduct business. Earnings from non-U.S. activities are subject to local country income tax and may also be subject to U.S. income tax. For interim periods, we record a tax provision or benefit based upon the estimated effective tax rate expected for the full fiscal year, adjusted for material discrete taxation matters arising during the interim periods. Our quarterly tax provision or benefit, and our quarterly estimate of the annual effective tax rate, are subject to significant variation due to several factors. These factors include items such as variability in accurately predicting pre-tax income/loss, the mix of jurisdictions in which we operate, intercompany transactions, changes in how we do business, tax law developments, including, but not limited to, impacts associated with the July 4, 2025 Bill, the realizability of our deferred tax assets, any related valuation allowance and relative changes in permanent tax benefits or expenses. We are currently evaluating the impact of the July 4, 2025 Bill and do not expect a material impact on our fiscal year 2025 consolidated financial statements.

The provision for income taxes and effective income tax rate are as follows (in thousands, except percentages):


	Three Months Ended						Nine Months Ended
	July 4, 2025			June 28, 2024			July 4, 2025			June 28, 2024
Income tax expense	$	7,546		$	4,309		$	14,403		$	11,567
Effective income tax rate	17.1		%	17.8		%	(17.0)		%	19.6		%

The difference between the U.S. federal statutory income tax rate of 21% and our effective income tax rate for the nine months ended July 4, 2025 was primarily driven by the non-deductibility of our loss on extinguishment of debt, favorable stock-based compensation and our research and development (“R&D”) tax credits. For the other periods reported above, the difference between the U.S. federal statutory income tax rate of 21% and our effective income tax rate was primarily driven by favorable stock-based compensation and R&D tax credits, offset by global intangible low taxed income (“GILTI”).

During the nine months ended June 28, 2024, we determined the earnings of one of our entities in India are no longer permanently reinvested, and due to the change in our position, we recorded a foreign withholding tax expense of $1.0 million associated with undistributed earnings.

We recognize deferred tax assets to the extent that we believe that these assets are more likely than not to be realized. In making this determination, we consider available positive and negative evidence. We look at factors that may impact the valuation of our deferred tax assets including results of recent operations, future reversals of existing taxable temporary differences, projected future taxable income and tax-planning strategies.

There were no unrecognized tax benefits as of July 4, 2025 and September 27, 2024. It is our policy to recognize any interest and penalties accrued related to unrecognized tax benefits in income tax expense. During the fiscal quarters ended July 4, 2025 and June 28, 2024, we did not make any accrual or payment of interest or penalties.

Purchase of software licenses included in liabilities	$	5,578	$	2,500

16. GEOGRAPHIC AND SIGNIFICANT CUSTOMER INFORMATION

We have one reportable operating segment that designs, develops, manufactures and markets semiconductors and modules. The determination of the number of reportable operating segments is based on the chief operating decision maker’s (“CODM”) use of financial information provided for the purposes of assessing performance and making operating decisions. The Company's CODM is its President and Chief Executive Officer and Chair of the Board. In evaluating financial performance and making operating decisions, the CODM primarily uses consolidated metrics. The Company assesses its determination of operating segments at least annually. We continue to evaluate our internal reporting structure, changes to our business and the potential impact of these changes on our segment reporting.

For each of the three and nine months ended July 4, 2025, our top ten customers represented 58% of total revenue and for the three and nine months ended June 28, 2024, our top ten customers represented 56% and 55% of total revenue, respectively.

17. RELATED-PARTY TRANSACTIONS

During the nine months ended July 4, 2025, we sold $0.2 million of commercial product to Empower RF Systems, Inc., a MACOM customer, and an affiliate of one of our directors.

18. SUBSEQUENT EVENTS

On July 25, 2025, we completed the RTP Fab Transfer in connection with the RF Business Acquisition, described in Footnote 3 - Acquisitions. As part of the RF Business Acquisition, in December 2023, $16.3 million of the purchase price was allocated to prepaid and other current assets associated with property and equipment, inventory and liabilities to be acquired with the RTP Fab Transfer. We are in the process of valuing the property and equipment, inventory and liabilities. As a result, we expect to recognize a gain or loss during the quarter ending October 3, 2025. The final amount will be determined as we obtain additional information.

Overview

We design, develop and manufacture differentiated semiconductor products and solutions for the Industrial and Defense (“I&D”), Data Center and Telecommunications (“Telecom”) industries for customers who demand high performance, quality and reliability. We are headquartered in Lowell, Massachusetts, with operational facilities throughout North America, Europe and Asia. We have more than 70 years of application expertise, combined with expertise in analog and mixed signal circuit design, compound semiconductor fabrication (including gallium arsenide (GaAs), gallium nitride (GaN), indium phosphide (InP) and specialized silicon), advanced packaging and back-end assembly and test. We offer a broad portfolio of thousands of standard and custom devices, which include integrated circuits (IC), multi-chip modules (MCM), diodes, amplifiers, switches and switch limiters, passive and active components and radio frequency (RF) and optical subsystems, which make up dozens of product lines that service over 6,000 end customers in our three primary markets. Our products are electronic components that our customers generally incorporate into larger electronic systems, such as wireless basestations, high-capacity optical networks, data center networks, radar, medical systems, satellite networks and test and measurement applications. Our primary end markets are: (1) I&D, which includes military and commercial radar, RF jammers, electronic countermeasures, communication data links, space-related electronics and various wired and wireless multi-market applications, which include industrial, medical, test and measurement and scientific applications; (2) Data Center, which includes intra-Data Center, Data Center Interconnect (DCI) applications, at 100G, 200G, 400G, 800G, 1.6T and higher speeds, enabled by our broad portfolio of analog ICs and photonic components for high speed connectivity customers; and (3) Telecom, which includes carrier infrastructure such as long-haul/metro, 5G and 6G infrastructure, satellite communications (“SATCOM”) and Fiber-to-the-X (FTTx)/passive optical network (PON), among others.

Description of Our Revenue

Revenue. Our revenue is derived from sales of high-performance RF, microwave, millimeter wave, optical and photonic semiconductor products. We design, integrate, manufacture and package differentiated, semiconductor-based products that we sell to customers through our direct sales organization, our network of independent sales representatives and our distributors.

We believe the primary drivers of our future revenue growth will include:

•continued growth in the demand for high-performance analog, digital and optical semiconductors in our three primary markets;

•introducing new products using advanced technologies, added features, higher levels of integration and improved performance;

•increasing content of our semiconductor solutions in customers’ systems through cross-selling our product lines;

•leveraging our core strength and leadership position in standard, catalog products that service all of our end applications; and

•engaging early with our lead customers to develop custom and standard products.

Our core strategy is to develop and innovate high-performance products that address our customers’ most difficult technical challenges in our primary markets: I&D, Data Center and Telecom.

We expect our revenue in the I&D market to be driven by the expanding product portfolio that we offer which services applications such as test and measurement, space-related electronics, civil and military radar, industrial, automotive, scientific and medical applications, further supported by growth in applications for our multi-market catalog products.

We expect our revenue in the Data Center market to be driven by the adoption of higher speed processing technologies and the upgrade of data center architectures to 100G, 200G, 400G, 800G and 1.6T interconnects, which we expect will drive adoption of higher speed optical and photonic components.

We expect our revenue in the Telecom market to be driven by 5G deployments, with continued upgrades and expansion of communications equipment, SATCOM networks and increasing adoption of our high-performance RF, millimeter wave, optical and photonic components.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based on our condensed consolidated financial statements. The preparation of financial statements, in conformity with GAAP, requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, the reported amounts of revenue and expenses during the reporting period and disclosure of contingent assets and liabilities at the date of the financial statements. By their nature, these estimates and judgments are subject to an inherent degree of uncertainty and could be material if our actual or expected experience were to change unexpectedly. On an ongoing basis, we re-evaluate our estimates and judgments.

We base our estimates and judgments on our historical experience and on other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making the judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates and material effects on our operating results and financial position may result. The accounting policies which our management believes involve the most significant application of judgment or involve complex estimation, are inventories and associated reserves; revenue reserves; business combinations; goodwill and intangible asset valuation; share-based compensation valuations and income taxes.

Business combinations

We apply significant estimates and judgments in order to determine the fair value of the identified tangible and intangible assets acquired, liabilities assumed and goodwill recognized in business combinations. The value of all assets and liabilities are recognized at fair value as of the acquisition date using a market participant approach. In measuring the fair value, we utilize a number of valuation techniques. When determining the fair value of property and equipment acquired, generally we must estimate the cost to replace the asset with a new asset taking into consideration such factors as age, condition and the economic useful life of the asset. When determining the fair value of intangible assets acquired, typically determined using a discounted cash flow valuation method, we use assumptions such as the timing and amount of future cash flows, discount rates, weighted average cost of capital and estimated useful lives. These assessments can be significantly affected by our judgments.

Goodwill and intangible asset valuation

Significant management judgment is required in our valuation of goodwill and intangible assets, many of which are based on the creation of forecasts of future operating results that are used in the valuation, including (i) estimation of future cash flows, (ii) estimation of the long-term rate of growth for our business, (iii) estimation of the useful life over which cash flows will occur, (iv) terminal values, if applicable, and (v) the determination of our weighted average cost of capital, which helps determine the discount rate. It is possible that these forecasts may change, and our performance projections included in our forecasts of future results may prove to be inaccurate. The value of our goodwill and purchased intangible assets could also be impacted by future adverse changes, such as a decline in the valuation of technology company stocks, including the valuation of our common stock, or a significant slowdown in the worldwide economy or in the semiconductor industry.

For additional information related to these and other accounting policies refer to Note 2 - Summary of Significant Accounting Policies to our Consolidated Financial Statements included in Item 8 of Part II, “Financial Statements and Supplementary Data,” of the 2024 Annual Report on Form 10-K and Note 1 - Basis of Presentation and Summary of Significant Accounting Policies to our condensed consolidated financial statements in this Quarterly Report on Form 10-Q.

Income taxes

We are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves estimating our current tax exposure and assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within our Consolidated Balance Sheets. We then assess the likelihood that our deferred tax assets will be recovered from future taxable income within

the relevant jurisdiction. To the extent we believe that recovery is not likely, we must establish a valuation allowance. We provide valuation allowances for certain deferred tax assets where it is more likely than not that any portion will not be realized.

The application of tax laws and regulations to calculate our tax liabilities is subject to legal and factual interpretation, judgment and uncertainty in a multitude of jurisdictions. Tax laws and regulations themselves are subject to change as a result of changes in fiscal policy, changes in legislation, the evolution of regulations, including the July 4, 2025 Bill, as well as court rulings. We recognize potential liabilities for anticipated tax audit matters in the United States and other tax jurisdictions based on our estimate of whether, and the extent to which, additional taxes and interest will be due. We record an amount as an estimate of probable additional income tax liability at the largest amount that we feel is more likely than not, based upon the technical merits of the position, to be sustained upon audit by the relevant tax authority.

Comparison of the Three and Nine Months Ended July 4, 2025 to the Three and Nine Months Ended June 28, 2024

Revenue. Our revenue increased by $61.6 million, or 32.3%, to $252.1 million for the three months ended July 4, 2025, from $190.5 million for the three months ended June 28, 2024, and our revenue increased by $177.2 million, or 33.5%, to $706.1 million for the nine months ended July 4, 2025, from $528.9 million for the nine months ended June 28, 2024. The increase in revenue in the three and nine months ended July 4, 2025 is described by end market in the following paragraphs.

Revenue from our primary markets, the percentage of change between the periods presented, and revenue by primary markets expressed as a percentage of total revenue in the periods presented were (in thousands, except percentages):


		Three Months Ended							Nine Months Ended
		July 4, 2025			June 28, 2024		% Change		July 4, 2025			June 28, 2024		% Change

Total		100.0	%		100.0	%			100.0	%		100.0	%

In the three months ended July 4, 2025, our I&D market revenue increased by $17.3 million, or 19.0%, compared to the three months ended June 28, 2024. In the nine months ended July 4, 2025, our I&D market revenue increased by $45.4 million, or 17.5%, compared to the nine months ended June 28, 2024. The increase in the three months ended July 4, 2025 was primarily driven by an increase in defense program revenue and higher sales of legacy products for industrial markets. The increase in the nine months ended July 4, 2025 was primarily driven by revenue growth from defense programs, partially offset by lower sales of legacy products for industrial markets.

In the three months ended July 4, 2025, our Data Center market revenue increased by $26.8 million, or 54.7%, compared to the three months ended June 28, 2024. In the nine months ended July 4, 2025, our Data Center market revenue increased by $71.6 million, or 50.6%, compared to the nine months ended June 28, 2024. The increase in the three and nine months ended July 4, 2025 was primarily driven by an increase in sales of high-performance analog Data Center products and fees primarily supporting high speed data rates from 100G up to 1.6T.

In the three months ended July 4, 2025, our Telecom market revenue increased by $17.5 million, or 34.6%, compared to the three months ended June 28, 2024. In the nine months ended July 4, 2025, our Telecom market revenue increased by $60.2 million, or 46.9%, compared to the nine months ended June 28, 2024. The increase in the three months ended July 4, 2025 was primarily driven by an increase in sales of products for 5G and SATCOM applications. The increase in the nine months ended July 4, 2025 was primarily driven by an increase in sales of products for 5G and SATCOM applications and recent acquisitions.

Certain areas of our end markets continue to be negatively impacted by macroeconomic and geopolitical conditions, which we expect may result in weaker near-term demand for our products across all three of our primary markets. In addition, we could be negatively affected by any weakening of global economic conditions, including as a result of the evolving impacts from tariffs, sanctions or other trade tensions (including implementation of new tariffs or retaliatory trade measures).

Gross profit. Gross margin was 55.3% and 53.2% for the three months ended July 4, 2025 and June 28, 2024, respectively, and 54.8% and 53.7% for the nine months ended July 4, 2025 and June 28, 2024, respectively. Gross profit was $139.4 million and $101.4 million for the three months ended July 4, 2025 and June 28, 2024, respectively, and $386.7 million and $283.9 million for the nine months ended July 4, 2025 and June 28, 2024, respectively. Gross profit increased for the three months ended July 4, 2025 as compared to the three months ended June 28, 2024 primarily as a result of higher sales, decreases in production supplies and lower intangible asset amortization, partially offset by increases in employee-related costs. Gross profit increased for the nine months ended July 4, 2025 as compared to the nine months ended June 28, 2024 primarily as a result of higher sales and decreases in production supplies, partially offset by increases in employee-related costs and share-based compensation.

Research and development. Research and development expense increased by $15.8 million, or 33.3%, to $63.4 million, or 25.1% of our revenue, for the three months ended July 4, 2025, compared to $47.5 million, or 25.0% of our revenue, for the three months ended June 28, 2024. Research and development expense increased by $49.0 million, 37.0%, to $181.6 million, or 25.7% of our revenue, for the nine months ended July 4, 2025, compared to $132.6 million, or 25.1% of our revenue, for the nine months ended June 28, 2024. Research and development expense increased in the three and nine months ended July 4, 2025 primarily due to increases in employee-related costs, partially due to acquisitions, share-based compensation expense and development-related supply costs.

Selling, general and administrative. Selling, general and administrative expense increased by $4.2 million, or 12.4%, to $38.4 million, or 15.2% of our revenue, for the three months ended July 4, 2025, compared to $34.2 million, or 17.9% of our revenue, for the three months ended June 28, 2024. Selling, general and administrative expense increased by $9.8 million, or 9.3%, to $115.1 million, or 16.3% of our revenue, for the nine months ended July 4, 2025, compared to $105.2 million, or 19.9% of our revenue, for the nine months ended June 28, 2024. Selling, general and administrative expense increased in the three months ended July 4, 2025 primarily due to an increase in employee-related costs and share-based compensation, partially offset by lower intangible asset amortization. Selling, general and administrative expense increased in the nine months ended July 4, 2025 primarily due to an increase in employee-related costs and share-based compensation, partially offset by decreases in acquisition-related transaction costs and intangible asset amortization.

Interest income. In the three months ended July 4, 2025, interest income was $7.6 million, compared to $5.8 million for the three months ended June 28, 2024. In the nine months ended July 4, 2025, interest income was $21.8 million, compared to $16.7 million for the nine months ended June 28, 2024. The increase for the three and nine months ended July 4, 2025 is primarily due to an increase in short-term investments and associated interest income.

Loss on extinguishment of debt. In the nine months ended July 4, 2025, we recognized a $193.1 million loss on exchange of our 2026 Convertible Notes. See Note 9 - Debt to our condensed consolidated financial statements in this Quarterly Report on Form 10-Q for additional information.

Provision for income taxes. Our income tax expense and effective income tax rates for the periods indicated were (in thousands, except percentages):


	Three Months Ended						Nine Months Ended
	July 4, 2025			June 28, 2024			July 4, 2025		June 28, 2024
Income tax expense	$	7,546		$	4,309		14,403		11,567
Effective income tax rate	17.1		%	17.8		%	(17.0)	%	19.6	%

The primary driver for the rate reduction for the three months ended July 4, 2025 as compared to the three months ended June 28, 2024 is the removal of a taxable income limitation on GILTI and foreign derived intangible income benefits. The primary driver for the rate reduction for the nine months ended July 4, 2025 as compared to the nine months ended June 28, 2024 is the non-deductibility of the loss on extinguishment of debt.

Our estimated annual effective tax rate for the fiscal year ending October 3, 2025 is expected to be approximately 15%, adjusted for discrete taxation matters arising during the interim periods, primarily the removal of the loss on extinguishment of debt of $193.1 million.

The Company is currently evaluating the impact of the July 4, 2025 Bill and does not believe there will be any significant impact to the current fiscal year ending October 3, 2025. The July 4, 2025 Bill restores the ability to deduct applicable research and development costs in the year they are incurred and no longer requires the deferral and amortization of these costs over five years, among other changes. We anticipate this change will impact the Company beginning in our fiscal year ending October 2, 2026. The July 4, 2025 Bill permits the acceleration of any unamortized balance of domestic research and development expenses which were previously deferred. In addition, the July 4, 2025 Bill increases the ITC relating to the CHIPS Act from 25% to 35% for qualifying assets placed into service after December 31, 2025.

Liquidity and Capital Resources

The following table summarizes our cash flow activities (in thousands):


	Nine Months Ended
	July 4, 2025		June 28, 2024
Cash and cash equivalents, beginning of period	$	146,806	$	173,952
Net cash provided by operating activities	165,732		100,311
Net cash used in investing activities	(246,131)		(148,615)
Net cash provided by (used in) financing activities	58,796		(8,434)
Foreign currency effect on cash	263		90
Cash and cash equivalents, end of period	$	125,466	$	117,304

Cash Flow from Operating Activities

Our cash flow from operating activities for the nine months ended July 4, 2025 of $165.7 million consisted of a net loss of $99.3 million plus adjustments of $299.3 million, to reconcile our net loss to cash provided by operating activities, less cash used in operating assets and liabilities of $34.3 million. Adjustments to reconcile our net loss to cash provided by operating activities primarily included loss on extinguishment of debt of $193.1 million, share-based compensation expense of $61.6 million and depreciation and intangible amortization expense of $45.6 million. In addition, cash used in operating assets and liabilities was $34.3 million for the nine months ended July 4, 2025, primarily driven by an increase in accounts receivables of $22.8 million and an increase in inventories of $20.6 million, partially offset by an increase in accounts payable of $16.5 million.

Our cash flow from operating activities for the nine months ended June 28, 2024 of $100.3 million consisted of a net income of $47.4 million plus adjustments of $89.0 million, to reconcile our net income to cash provided by operating activities, less cash used in operating assets and liabilities of $36.1 million. Adjustments to reconcile our net income to cash provided by operating activities primarily included depreciation and intangible amortization expense of $49.4 million and share-based compensation expense of $34.1 million. In addition, cash used in operating assets and liabilities was $36.1 million for the nine months ended June 28, 2024, primarily driven by an increase in accounts receivables of $17.9 million, an increase in inventories of $25.1 million, a decrease of $6.1 million in accrued and other liabilities, partially offset by an increase of $14.7 million in accounts payable. The increase in inventory is primarily due to timing of certain program shipments and inventory builds to support future revenue. The increases in accounts receivable and accounts payable were primarily a result of the integration of the RF Business during the nine months ended June 28, 2024.

Cash Flow from Investing Activities

Our cash flow used in investing activities for the nine months ended July 4, 2025 of $246.1 million consisted primarily of purchases of $450.9 million of short-term investments, purchase of property under financing arrangement of $28.8 million, capital expenditures of $22.3 million, cash paid for acquisitions, net of cash acquired of $12.7 million and other investing activities of $11.0 million, offset by proceeds of $279.6 million for the sale and maturity of short-term investments.

We anticipate our capital expenditures for our fourth fiscal quarter ending October 3, 2025 to be in the range of $17.0 million to $23.0 million, which includes the purchase of approximately $12.0 million of production-related equipment to expand capacity at the RTP Fab.

Our cash flow used in investing activities for the nine months ended June 28, 2024 of $148.6 million consisted primarily of cash paid for acquisitions, net of cash acquired of $72.6 million for acquisitions, capital expenditures of $17.3 million and purchases of $330.7 million of short-term investments, offset by proceeds of $274.1 million for the sale and maturity of short-term investments. For additional information on the consideration paid for our acquisitions, see Note 3 - Acquisitions to our condensed consolidated financial statements in this Quarterly Report on Form 10-Q.

Cash Flow from Financing Activities

During the nine months ended July 4, 2025, our cash provided by financing activities of $58.8 million was primarily related to $86.6 million of proceeds from convertible notes, $28.8 million of proceeds from financing arrangement and $10.2 million of proceeds from stock option exercises and employee stock purchases, partially offset by $42.7 million of common stock withheld associated with employee taxes on vested equity awards and $23.2 million of fees for the convertible note exchange and payments for debt issuance costs.

During the nine months ended June 28, 2024, our cash used in financing activities of $8.4 million was primarily related to $13.9 million of common stock withheld associated with employee taxes on vested equity awards, partially offset by $6.5 million of proceeds from stock option exercises and employee stock purchases.

Liquidity

As of July 4, 2025, we held $125.5 million of cash and cash equivalents, primarily deposited with financial institutions, as well as $609.8 million of liquid short-term investments. The undistributed earnings of certain foreign subsidiaries are considered indefinitely reinvested for the periods presented and we do not intend to repatriate such earnings. We believe the decision to reinvest these earnings will not have a significant impact on our liquidity. As of July 4, 2025, cash held by our indefinitely reinvested foreign subsidiaries was $8.7 million, which, along with cash generated from foreign operations, is expected to be used in the support of international growth and working capital requirements as well as the repayment of certain intercompany loans.

On December 19, 2024, we exchanged approximately $288.8 million in aggregate principal amount of our 2026 Convertible Notes (as defined in Note 9 - Debt to our condensed consolidated financial statements in this Quarterly Report on Form 10-Q) for approximately $257.7 million in aggregate principal amount of the 2029 Convertible Notes (as defined in Note 9 - Debt to our condensed consolidated financial statements in this Quarterly Report on Form 10-Q), 1,582,958 newly-issued shares of the Company’s common stock, issued at a fair value of $205.9 million, and $17.6 million in cash. We also issued approximately $86.6 million in aggregate principal amount of the 2029 Convertible Notes, and net proceeds, net of amounts paid associated with the exchange, totaled approximately $63.7 million and are expected to be used for general corporate purposes. As of July 4, 2025, the aggregate principal balances of the 2026 Convertible Notes and 2029 Convertible Notes are $161.2 million and $344.3 million, respectively, and we are required to pay cash for the principal amount of the notes upon conversion.

During the fiscal quarter ended July 4, 2025, our common stock price for at least 20 trading days (whether or not consecutive) during the 30 consecutive trading days ending July 4, 2025 was greater than $106.76 on each applicable trading day. Therefore, holders of our 2026 Convertible Notes may convert their notes at their option at any time during the subsequent fourth fiscal quarter ended October 3, 2025 in multiples of $1,000 principal amount. For additional information on the 2026 Convertible Notes, see Note 9 - Debt to our condensed consolidated financial statements in this Quarterly Report on Form 10-Q.

On January 14, 2025, we announced the execution of a preliminary, non-binding agreement with the CHIPS Program Office, which could provide for proposed direct funding from the U.S. Department of Commerce under the CHIPS Act of up to $70 million.

We plan to use our remaining available cash and cash equivalents and short-term investments for general corporate purposes, including working capital, payment on the 2026 Convertible Notes and 2029 Convertible Notes, or for the acquisition of or investment in complementary technologies, design teams, products and businesses. We believe that our cash and cash equivalents, short-term investments and cash generated from operations will be sufficient to meet our working capital requirements for at least the next twelve months. We may need to raise additional capital from time to time through the issuance and sale of equity or debt securities, and there is no assurance that we will be able to do so on favorable terms or at all.

As of July 4, 2025, we had no off-balance sheet arrangements.

For additional information related to our Liquidity and Capital Resources, see Note 9 - Debt to our condensed consolidated financial statements in this Quarterly Report on Form 10-Q.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risk in the ordinary course of business, which consists primarily of interest rate risk associated with our cash and cash equivalents and short-term investments, as well as foreign exchange rate risk.

Interest rate risk. The primary objectives of our investment activity are to preserve principal, provide liquidity and invest excess cash for an average rate of return. To minimize market risk, we maintain our portfolio in cash and diversified investments, which may consist of corporate bonds, bank deposits, money market funds, commercial paper and U.S. Treasury securities. The interest rates are variable and fluctuate with current market conditions. The risk associated with fluctuating interest rates is limited to this investment portfolio. We believe that a 1% change in interest rates would have a $7.4 million impact on our annual interest income, based on cash and cash equivalents and short-term investments balances as of July 4, 2025. We believe that a change in interest rates would not have a material impact on our results of operations, however, such change(s) could impact net income and earnings per share. We do not enter into financial instruments for trading or speculative purposes.

Foreign currency risk. To date, our international customer agreements have been denominated primarily in U.S. dollars. Accordingly, we have limited exposure to foreign currency exchange rates. The functional currency of a majority of our foreign operations continues to be in U.S. dollars with the remaining operations being local currency. Changes in the value of the U.S. dollar relative to other currencies could make our products more expensive, which could negatively impact demand in certain regions, reduce or delay customer orders, or otherwise negatively affect how customers do business with us. The effects of exchange rate fluctuations on the net assets of the majority of our operations are accounted for as transaction gains or losses. We believe that a change of 10% in such foreign currency exchange rates would not have a material impact on our financial position or results of operations.

We have entered into foreign currency exchange hedging contracts to reduce the impact of foreign currency changes on certain intercompany foreign currency denominated debt. These foreign currency forward contracts are entered into for periods consistent with currency transaction exposures, generally one month. They are not designated as cash flow or fair value hedges under ASC 815, Derivatives and Hedging. These forward contracts are marked-to-market with changes in fair value recorded to earnings. As of July 4, 2025, we had $33.0 million in notional forward foreign currency contracts, which were denominated in Euro and Yen.

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, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) were effective as of July 4, 2025.

Changes in Internal Control over Financial Reporting

There were no changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) that occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Controls

Our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance of achieving the desired control objectives. Our management recognizes that any control system, no matter how well designed and operated, is based upon certain judgments and assumptions and cannot provide absolute assurance that its objectives will be met. Similarly, an evaluation of controls cannot provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected.

PART II—OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

See Note 12 - Commitments and Contingencies to our condensed consolidated financial statements in this Quarterly Report on Form 10-Q for information about our legal proceedings.
