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, stockholders' equity and cash flows of MACOM Technology Solutions Holdings, Inc. (“~~MACOM”,~~MACOM,” the ~~“Company”, “us”,~~“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 ~~30, 2022~~29, 2023 is as reported in our audited consolidated financial statements as of that date. Our accounting policies are described in the notes to our September ~~30, 2022~~29, 2023 consolidated financial statements, which were included in our Annual Report on Form 10-K for our fiscal year ended September ~~30, 2022~~29, 2023 filed with the SEC on November ~~14, 2022~~13, 2023 (the ~~“2022~~“2023 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 ~~2022~~2023 Annual Report on Form 10-K.

Principles of Consolidation, Basis of Presentation and Reclassification—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. In the condensed consolidated financial statements, Interest income has been reclassified to conform to the current year presentation.

We have a 52- or 53-week fiscal year ending on the Friday closest to the last day of September. Fiscal years ~~2023~~2024 and ~~2022~~2023 each include 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.

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.

Recent Accounting Pronouncements—Our Recent Accounting Pronouncements are described in our ~~2022~~2023 Annual Report on Form 10-K.

Pronouncements for Adoption in Subsequent Periods

~~The~~In November 2023, the FASB issued ASU ~~2020-04,~~2023-07, ~~Reference Rate Reform~~Segment Reporting (Topic ~~848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, amended by ASU 2022-06,~~ ~~Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848~~280) Improvements to Reportable Segment Disclosures, which ~~provides optional expedients~~improves disclosures about a public entity’s reportable segments and ~~exceptions to applying the guidance on contract modifications, hedge accounting,~~addresses requests from investors and other ~~transactions, to simplify the accounting~~allocators of capital for ~~transitioning from the London Interbank Offered Rate, and other interbank offered rates expected to be discontinued, to alternative reference rates.~~additional, more detail information about a reportable segment’s expenses. The ~~guidance~~amendments in this update ~~was effective upon its issuance. If elected, the guidance is~~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 ~~prospectively through~~on a retrospective basis. The amendments in this update are effective for fiscal years beginning after December ~~31, 2024.~~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 ~~potential~~ adoption of this ASU will have on our consolidated financial statements ~~including, but not limited~~and related disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) Improvements to Income Tax Disclosures, which require 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 potential effect of the adoption of this ASU will have on our ~~Credit Agreement (defined below). For additional information regarding our Credit Agreement, refer to~~ ~~Note 8 - Debt.~~consolidated financial statements and related disclosures.

2. REVENUE

Disaggregation of Revenue

We disaggregate revenue from contracts with customers by markets and geography, as we believe it best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors.

The following tables present our revenue disaggregated by markets and geography (in thousands):

(2)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 and Cayman Islands as presented above.

Revenue by geographic region is aggregated by customer billing address.

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 three months ended December ~~30, 2022~~29, 2023 (in thousands, except percentage):

December 30, 2022 September 30, 2022 $ Change % Change
Contract liabilities $ 3,404 $ 3,916 $ (512) (13) %


	December 29, 2023		September 29, 2023		$ Change		% Change
Contract liabilities	$	5,604	$	2,762	$	2,842	103	%

During the three months ended December ~~30, 2022,~~29, 2023, we recognized sales of ~~$1.4~~$2.4 million that were included in the contract liabilities balance as of the beginning of the period. The ~~decrease~~increase in contract liabilities during the three months ended December ~~30, 2022~~29, 2023 was primarily related to ~~recognition of revenue that was previously deferred for products and services invoiced~~invoicing prior to when ~~certain of~~ our customers ~~obtained~~obtain control of such products ~~and/~~and or

services.

3. ACQUISITIONS

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 of Wolfspeed, Inc. (“Wolfspeed”) (the “RF Business,”), which was accounted for as a business combination (the “RF Business Acquisition”). The RF Business includes a portfolio of gallium nitride (“GaN”) on Silicon Carbide (“SiC”) products used in high-performance RF and microwave applications. In connection with the RF Business Acquisition, we expect to assume control of a wafer fabrication facility in Research Triangle Park, North Carolina (the “RTP Fab”) approximately two years following the closing of the RF Business Acquisition (the “RTP Fab Transfer”). Prior to the RTP Fab Transfer, Wolfspeed will continue 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, subject to customary purchase price adjustments and 711,528 shares of our common stock, with a fair value of $60.8 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 are subject to restrictions on the sale of shares until transfer of the RTP Fab to the Company is complete. In addition, if the RTP Fab has not transferred by the fourth anniversary of the closing date of the RF Business Acquisition, Wolfspeed will forfeit 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 December 29, 2023, we incurred acquisition-related transaction costs of approximately $7.1 million, which are included in selling, general and administrative expense. We did not incur acquisition-related transaction costs associated with the RF Business Acquisition during the three months ended December 30, 2022.

The following table summarizes the preliminary estimate of the purchase price (in thousands, except shares and closing share price amount):


			At Acquisition Date as Reported December 29, 2023

Cash purchase consideration			$	75,000
Number of shares of MACOM common stock issued at closing	711,528
MACOM closing stock price on acquisition date	$	85.41
Equity purchase consideration			60,772

Total purchase consideration			$	135,772

The purchase price for the RF Business Acquisition has been allocated based on preliminary estimates of fair values of the acquired assets and assumed liabilities at the date of acquisition as follows (in thousands):

Current assets	$	160
Inventory	23,574
Property and equipment	35,415
Intangible assets	60,000
Prepayment for net assets associated with the RTP Fab Transfer	19,450
Other non-current assets	6,735

Total assets acquired	145,334
Current liabilities	6,474
Long-term liabilities	3,088
Total liabilities assumed	9,562
Purchase Price	$	135,772

Intangible assets consist of technology, customer relationships, a favorable contract and backlog with fair values of $22.0 million, $21.5 million, $15.0 million and $1.5 million, respectively, and useful lives of 4.8 years, 8.8 years, 2.0 years and 0.8 years, respectively. We used variations of income approaches with estimates and assumptions developed by us to determine the fair values of technology, customer relationships, the favorable contract and backlog. We valued technology by using the relief-from-royalty method, customer relationships and backlog by using the multi-period excess earnings method, and the favorable contract by using the discounted cash flow method. 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 $19.5 million for the net assets associated with the RTP Fab Transfer, classified in Other long-term assets in our condensed consolidated balance sheet, relates to the estimated future fair value of property and equipment, inventory and liabilities that we will assume control of at the time of the RTP Fab Transfer. The cost and market approaches were used in determining the fair value of $14.1 million for property and equipment at the RTP Fab Transfer date.

The determination and allocation of purchase price consideration is based on preliminary estimates of fair value; such estimates and assumptions are subject to change within the measurement period (up to one year from the acquisition date). As of December 29, 2023, the purchase price allocation for the RF Business remains open as we gather additional information regarding the fair value of consideration transferred, the assets acquired and the liabilities assumed, primarily in relation to the valuation of intangibles, inventory, property and equipment, leases, the prepayment for the assets and liabilities to be conveyed with the RTP Fab Transfer and contingencies.

The RF Business has been included in our consolidated financial statements since the date of acquisition. During the fiscal quarter ended December 29, 2023, the RF Business contributed approximately $6.2 million of our total revenue. The net income associated with the RF Business did not materially impact our consolidated net income for the quarter ended December 29, 2023.

Consolidated estimated pro forma unaudited revenue for the fiscal quarters ended December 29, 2023 and December 30, 2022, as if the RF Business Acquisition had occurred on October 1, 2022, is $184.0 million and $222.4 million, respectively. Consolidated pro forma net loss for the fiscal quarters ended December 29, 2023 and December 30, 2022, as if the RF Business Acquisition had occurred on October 1, 2022, is $13.9 million and $31.3 million, respectively. Pro forma revenue and net loss 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. Pro forma net loss includes business combination accounting effects from the RF Business Acquisition, primarily amortization expense from acquired intangible assets, acquisition transaction costs and tax-related effects. Pro forma earnings for the three months ended December 29, 2023 was adjusted to exclude transaction costs of $15.5 million incurred during the quarter and pro forma earnings for the three months ended December 30, 2022 was adjusted to include $41.8 million of transaction costs incurred associated with the RF Business Acquisition.

MESC— On May 31, 2023, we completed the acquisition of the key manufacturing facilities, capabilities, technologies and other assets and certain specified liabilities of OMMIC SAS, a semiconductor manufacturer based in Limeil-Brévannes, France with expertise in wafer fabrication, epitaxial growth and monolithic microwave integrated circuit (“MMIC”) processing and design. We are referring to this acquisition as the MACOM European Semiconductor Center Acquisition (the “MESC Acquisition”) and it was accounted for as a business combination. We completed the MESC Acquisition to expand our European footprint and to enable us to offer higher frequency gallium arsenide (“GaAs”) and GaN MMICs. Total cash consideration paid for the MESC Acquisition was approximately $36.9 million and was funded with cash-on-hand. During the three months ended December 29, 2023 and December 30, 2022, we incurred acquisition-related transaction costs of approximately $0.3 million and $0.8 million, respectively, which are included in selling, general and administrative expense.

The purchase price for the MESC Acquisition has been allocated based on preliminary estimates of fair values of the acquired assets and assumed liabilities at the date of acquisition as follows (in thousands):


	At Acquisition Date as Reported December 29, 2023

Current assets	$	297
Inventory	3,790
Property and equipment	30,538
Intangible assets	5,966

Total assets acquired	40,591
Current liabilities	3,734
Total liabilities assumed	3,734
Purchase Price	$	36,857

As part of the acquisition, we assumed a lease agreement for the manufacturing facilities in France that provides us with the option to purchase the real property for an immaterial price at the end of the lease term, in October 2024. We expect to exercise this bargain purchase option and have recorded a right-of-use-asset of $24.7 million in Property and equipment. The real property was valued using a market approach.

Intangible assets consist of technology and customer relationships of $4.9 million and $1.1 million, respectively, and both having useful lives of 8.3 years. We used the income approach to determine the fair value of the definite-lived intangible assets and the cost and market approaches to determine the fair value of our property, plant and equipment. We amortize definite-lived assets based on the pattern over which we expect to receive the economic benefit from these assets.

The determination and allocation of purchase price consideration is based on preliminary estimates of fair value; such estimates and assumptions are subject to change within the measurement period (up to one year from the acquisition date). As of December 29, 2023, the purchase price allocation for the MESC Acquisition remains open as we gather additional information regarding the assets acquired and the liabilities assumed, primarily in relation to the valuation of intangibles, inventory, property and equipment, leases, liabilities and contingencies. We did not recognize goodwill associated with this acquisition and there were no measurement period adjustments recognized during the quarter ended December 29, 2023.

Linearizer Technology, Inc.— On March 3, 2023, we completed the acquisition of Linearizer Technology, Inc. (“Linearizer”), a developer of modules and subsystems, including SSPAs, microwave predistortion linearizers and microwave photonics based in Hamilton, New Jersey (the “Linearizer Acquisition”), which was accounted for as a business combination. We acquired Linearizer to further strengthen our component and subsystem design expertise in our target markets. In connection with the Linearizer Acquisition, we acquired all of the outstanding shares of Linearizer for total cash consideration of approximately $51.6 million, subject to customary purchase price adjustments. We funded the Linearizer Acquisition with cash-on-hand. During the three months ended December 29, 2023, we incurred acquisition-related transaction costs of approximately less than $0.1 million which are included in selling, general and administrative expense. There were no transaction costs for the three months ended December 30, 2022. The Linearizer Acquisition was accounted for as a business combination and the operations of Linearizer have been included in our consolidated financial statements since the date of acquisition.

The purchase price for the Linearizer Acquisition has been allocated based on preliminary estimates of fair values of the acquired assets and assumed liabilities at the date of acquisition as follows (in thousands):


	At Acquisition Date as Reported September 29, 2023		Measurement Period Adjustments		At Acquisition Date as Reported December 29, 2023

Current assets	$	2,819	$	—	$	2,819

Intangible assets consist of customer relationships, technology and trade name with fair values of $20.7 million, $7.1 million and $1.8 million, respectively, and useful lives of 8.6 years, 7.6 years and 7.6 years, respectively. We used the income approach to determine the fair value of the definite-lived intangible assets and the cost and market approaches to determine the fair value of our property, plant and equipment. We amortize definite-lived assets based on the pattern over which we expect to receive the economic benefit from these assets. The intangible assets and goodwill acquired will be amortizable for tax purposes due to the Internal Revenue Code of 1986 (IRC) Section 338 election filed.

The determination and allocation of purchase price consideration is based on preliminary estimates of fair value; such estimates and assumptions are subject to change within the measurement period (up to one year from the acquisition date). During the three months ended December 29, 2023, we increased the fair value of inventory by $1.4 million with an offsetting reduction to Goodwill. As of December 29, 2023, the purchase price allocation for Linearizer remains open as we gather additional information regarding the assets acquired and the liabilities assumed, primarily in relation to the valuation of contingencies.

4. INVESTMENTS

All investments are short-term in nature and are invested in corporate bonds, ~~and~~ commercial paper, and U.S. Treasury securities and are classified as available-for-sale. These certificates of deposit, corporate bonds, commercial paper and U.S. Treasury securities 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):

Over one year	Over one year	110,161		98,439
Total available-for-sale investments	Total available-for-sale investments	$	468,577	$	466,580

We have determined that the gross unrealized losses on available for sale securities as of December ~~30, 2022~~29, 2023 and September ~~30, 2022~~29, 2023 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.

During the three months ended December 30, 2022 and December 31, 2021, Interest income (expense), net included interest income on short-term investments of $3.7 million and $0.3 million, respectively.

Other Investments—As of December ~~30, 2022,~~29, 2023, we held a non-marketable equity investment in Series B preferred stock of a privately held manufacturing corporation with preferred liquidation rights over other equity shares. As the equity securities do not have a readily determinable fair value and do not qualify for the practical expedient under Accounting Standards Codification 820, Fair Value Measurement, we have elected to account for this investment at cost less any impairment. We

evaluate this investment for impairment at each balance sheet date. As of December ~~30, 2022~~29, 2023 and September ~~30, 2022,~~29, 2023, the carrying value of this investment was $2.5 million and it was classified as a long-term investment.

On December 23, 2021, we sold our non-controlling investment of less than 10% in the outstanding equity of a private company to one of the other limited liability company members, pursuant to the terms of a previously negotiated call option included in the private company’s limited liability company agreement, as amended and restated (the “LLC Agreement”), in exchange for a predetermined fixed price as set forth in the LLC Agreement of approximately $127.8 million in cash consideration. As of December 23, 2021, the carrying value of this investment was approximately $9.5 million. As a result of this transaction, during the three months ended December 31, 2021, we recorded a gain of $118.2 million in Other (expense) income, net in our condensed consolidated statements of operations.

4.5. FAIR VALUE

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 months ended December ~~30, 2022.~~

29, 2023.

Total long-term debt $ 566,332 $ 565,920

~~Term Loans~~

As of December 30, 2022, we are party to a credit agreement, dated as of May 8, 2014, with a syndicate of lenders and Goldman Sachs Bank USA, as administrative agent (as amended on February 13, 2015, August 31, 2016, March 10, 2017, May 19, 2017, May 2, 2018 and May 9, 2018, the “Credit Agreement”).

As of December 30, 2022, the Credit Agreement consisted of term loans with an initial aggregate principal amount of $700.0 million (the “Term Loans”) that will mature in May 2024 and bear interest at: (i) for LIBOR loans for any interest period, a rate per annum equal to the LIBOR rate as determined by the administrative agent, plus an applicable margin of 2.25%; and (ii) for base rate loans, a rate per annum equal to the greater of (a) the prime rate quoted in the print edition of the Wall Street Journal, Money Rates Section, (b) the federal funds rate plus one-half of 1.00% and (c) the LIBOR rate applicable to a one-month interest period plus 1.00% (but, in each case, not less than 1.00%), plus an applicable margin of 1.25%.

As of December 30, 2022, there are no minimum principal repayments on the Term Loans until May 2024 when the remaining principal balance of $120.8 million becomes due. The fair value of the Term Loans was estimated to be approximately $119.6 million and $120.2 million as of December 30, 2022 and September 30, 2022, respectively, and was determined using Level 2 inputs, including a quoted price from a financial institution.

As of December 30, 2022, approximately $0.5 million of deferred financing costs remain unamortized related to the Term Loans and is recorded as a direct reduction of the recognized debt liabilities in our accompanying condensed consolidated balance sheet.

~~The Term Loans are secured by a first priority lien on substantially all of our assets and provide that we must comply with certain financial and non-financial covenants.~~

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 “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 aggregate principal balance of the 2026 Convertible Notes is $450.0 million. The 2026 Convertible Notes will mature on March 15, 2026, unless earlier converted, redeemed or repurchased.

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.

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 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 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 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 Indenture). We may not redeem the notes prior to March 20, 2024. 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 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.

~~In connection with the adoption of ASU 2020-06,~~ Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, on October 2, 2021 we reclassified $72.2 million, consisting of $73.1 million of principal and issuance costs of $0.9 million, previously allocated to the conversion feature, from additional paid-in capital to long-term debt on our condensed consolidated balance sheet as of October 2, 2021. The reclassification was recorded to combine the two legacy units of account into a single instrument classified as a liability. We also recognized a cumulative effect adjustment of $7.5 million to accumulated deficit on our condensed consolidated balance sheet as of October 2, 2021, that was primarily driven by the derecognition of interest expense related to the accretion of the Debt Discount as required under the legacy accounting guidance. Under ASU 2020-06, we will no longer incur non-cash interest expense related to the accretion of the debt discount associated with the embedded conversion option.

For the three months ended December ~~30, 2022~~29, 2023 and December ~~31, 2021,~~30, 2022, total interest expense for the 2026 Convertible Notes was $0.3 ~~million.~~million and $0.3 million, respectively.

The fair value of our 2026 Convertible Notes ~~including the conversion feature,~~ was $~~448.4~~556.2 million and ~~$411.4~~$512.5 million as of December ~~30, 2022~~29, 2023 and September ~~30, 2022,~~29, 2023, 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 December ~~30, 2022;~~29, 2023; the full amount of $450.0 million is due in fiscal year 2026.

Term Loans

As of December 30, 2022, we were party to a credit agreement, dated as of May 8, 2014, with a syndicate of lenders and Goldman Sachs Bank USA, as administrative agent (as amended on February 13, 2015, August 31, 2016, March 10, 2017, May 19, 2017, May 2, 2018 and May 9, 2018, the “Credit Agreement”).

On August 2, 2023, the Credit Agreement was terminated when we paid the total outstanding principal balance on our Term Loans of $120.8 million and accrued interest of less than $0.1 million with cash-on-hand.

There was no interest expense for the Term Loans for the three months ended December 29, 2023. For the three months ended December 30, 2022, total interest expense for the Term Loans was $1.8 million.

9.10. 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. These systems are expected to reduce our consumption of energy while delivering sustainable, resilient energy for heating and cooling. We do not own these systems; however, we control the use of the assets during operation. As of December ~~30, 2022~~29, 2023 and September ~~30, 2022~~29, 2023, the net book value of the systems in Property and equipment, net was ~~$9.3~~$8.7 million and ~~$9.8~~$8.9 million, respectively, and the corresponding liability was ~~$9.7~~$9.5 million and ~~$9.8~~$9.6 million, respectively, primarily classified in Financing obligation on our condensed consolidated balance sheet. The initial financing obligation was calculated based on future fixed payments allocated to the power generator of $16.8 million over the 15-year term, discounted at an implied discount rate of 7.4%, and the remaining future minimum payments are for power purchases. ~~In total,~~As of December 29, 2023 and September 29, 2023, we have ~~$27.2~~$25.3 million and $25.5 million, respectively, in remaining fixed payments over a 14-year term associated with the power purchase agreement, of which ~~has~~$15.7 million and $15.9 million, respectively, is included in our consolidated balance sheets on a ~~15-year term.~~discounted basis.

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 months ended December ~~30, 2022.~~29, 2023.

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 December ~~30, 2022.~~29, 2023.

Stock Plans

As of December ~~30, 2022,~~29, 2023, we had ~~4.6~~3.9 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 ~~1.3~~1.2 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 December ~~30, 2022~~29, 2023 are subject to accelerated vesting upon a change in control of the Company.

Incentive Stock Units

~~Outside of~~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 December ~~30, 2022~~29, 2023 and September ~~30, 2022,~~29, 2023, the fair value of outstanding ISUs was ~~$5.4~~$6.0 million and ~~$4.9~~$5.0 million, respectively, and the associated accrued compensation liability was ~~$2.5~~$2.3 million and ~~$3.6~~$3.3 million, respectively. During the three

months ended December 29, 2023 and December 30, 2022, ~~and December 31, 2021,~~ we recorded an expense for ISU awards of ~~$1.3~~$0.5 million and ~~$1.4~~$1.3 million, respectively. These expenses are not included in the share-based compensation expense totals below.

(1) The amount shown represents performance adjustments for performance-based awards. These were granted in prior fiscal years and vested during the three months ended December ~~30, 2022~~29, 2023 based on the Company’s achievement of adjusted earnings per share performance conditions.

Stock awards that vested during the three months ended December ~~30, 2022~~29, 2023 and December ~~31, 2021~~30, 2022 had combined fair values of ~~$66.8~~$33.3 million and ~~$69.9~~$66.8 million, respectively, as of the vesting date. RSUs granted generally vest over a period of three or four years.

Market-based PRSUs

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 3three 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 assumptions used to value the awards are as follows:

There were no options exercised during the three months ended December 30, 2022.

~~13.~~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 current 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 its 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, the realizability of our deferred tax assets and related valuation allowance and relative changes in permanent tax benefits or expenses.

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

Three Months Ended

The difference between the U.S. federal statutory income tax rate of 21% and our effective income tax rate for the three months ended December 29, 2023 was primarily driven by favorable stock based compensation and research and development (“R&D”) tax credits, partially offset by foreign withholding taxes and global intangible low taxed income (“GILTI”). The difference between the U.S. federal statutory income tax rate of 21% and our effective income tax rate for the three months ended December 30, 2022 was primarily driven by tax on ~~global intangible low-taxed income (“GILTI”),~~GILTI and non-deductible compensation, ~~and state income taxes~~ partially offset by ~~income taxed in foreign jurisdictions generally at lower~~R&D tax ~~rates, and research and development (“R&D”) tax~~ credits. ~~The difference between the U.S. federal statutory income tax rate of 21% and our effective income tax rate for~~

On September 30, 2022, we released the majority of the valuation allowances against U.S. federal and state deferred tax assets including operating loss (“NOL”) carryforwards, R&D tax credit carryforwards and other deferred tax items relating to temporary differences. We continued our ongoing assessment of the realizability of our deferred tax assets and did not note any significant changes from our assessment on September 30, 2022. We continue to maintain a partial valuation allowance against certain of our deferred tax assets primarily relating to state NOLs and R&D tax credit carryforwards which are not expected to be realized. 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 December ~~30, 2022~~29, 2023 and September ~~30, 2022.~~29, 2023. It is our policy to recognize any interest and penalties accrued related to unrecognized tax benefits in income tax expense. During the fiscal quarter ended December ~~30, 2022,~~29, 2023, we did not make any accrual or payment of interest or penalties.

~~15.~~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. 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 and the potential impact of any changes on our segment reporting.

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: ~~Telecom,~~ I&D, Data Center and ~~Data Center.~~

We expect our revenue in the Telecom market to be driven by 5G deployments, with continued upgrades and expansion of communications equipment, and increasing adoption of our high-performance RF, millimeter wave, optical and photonic components.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, satellite communications, 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 cloud-based services and the upgrade of data center architectures to 100G, 200G, 400G and 800G 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, satellite communications 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 optical communications equipment or 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 ~~2022~~2023 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.

The difference between the U.S. federal statutory income tax rate of 21% and our effective income tax rate for the three months ended December 29, 2023 was primarily driven by favorable stock based compensation and R&D tax credits, partially offset by foreign withholding taxes and GILTI. The difference between the U.S. federal statutory income tax rate of 21% and our effective income tax rate for the three months ended December 30, 2022, was primarily driven by tax on GILTI and non-deductible compensation, ~~and state income taxes~~ partially offset by ~~income taxed in foreign jurisdictions generally at lower tax rates, and~~ R&D tax credits. The difference between the U.S. federal statutory income tax rate of 21% and our effective income tax rate for the three months ended December 31, 2021 was primarily driven by the full valuation allowance against any expense associated with income in the U.S. and income taxed in foreign jurisdictions generally at lower tax rates, where a valuation allowance does not apply. Our estimated annual effective tax rate for the year ending September ~~29, 2023~~27, 2024 is expected to be approximately ~~30%~~23%, adjusted for discrete taxation matters arising during the interim periods.

Liquidity

As of December ~~30, 2022,~~29, 2023, we held ~~$126.2~~$163.6 million of cash and cash equivalents, primarily deposited with financial institutions, as well as ~~$468.6~~$299.7 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 December ~~30, 2022,~~29, 2023, cash held by our indefinitely reinvested foreign subsidiaries was ~~$14.1~~$7.3 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.

We plan to use our remaining available cash and cash equivalents and short-term investments for general corporate purposes, including working capital, 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 December ~~30, 2022,~~29, 2023, we had no off-balance sheet arrangements.

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, short-term investments and our variable rate debt, 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 ~~commercial paper.~~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 10% change in interest rates would not have a material impact on our financial position or results of operations. We do not enter into financial instruments for trading or speculative purposes.

~~Our exposure to interest rate risk also relates to~~On August 2, 2023, we paid the ~~increase or decrease in the amount of interest expense we must pay on the~~total outstanding ~~debt under the Credit Agreement. The interest rates~~principal balance on our Term Loans are variable interest rates based on our lender’s prime rate or a LIBOR rate, in each case plus an applicable margin, which exposes us to market interest rate risk when we have outstanding borrowings under the Credit Agreement. As of December 30, 2022, we had $120.8 million of outstanding borrowings under the Credit Agreement. Assuming our outstanding debt remains constant under the Credit Agreement for an entire year and the applicable annual interest rate increases or decreases by 1%, our annual interest expense would increase or decrease by $1.2 million.Loans. The interest rates on our 2026 Convertible Notes are fixed and therefore not subject to interest rate risk. For additional information regarding our Term Loans and Convertible Notes, refer to Note 9 - Debt.

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. In the future, we may enter into foreign currency exchange hedging contracts to reduce our exposure to changes in exchange rates.

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 December ~~30, 2022.~~29, 2023.

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.
