MACOM TECHNOLOGY SOLUTIONS HOLDINGS, INC.

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 October 1, 2021 is as reported in our audited consolidated financial statements as of that date. Our accounting policies are described in the notes to our October 1, 2021 consolidated financial statements, which were included in our Annual Report on Form 10-K for our fiscal year ended October 1, 2021 filed with the SEC on November 15, 2021 (the “2021 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 2021 Annual Report on Form 10-K.

Principles of Consolidation—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 years 2022 and 2021 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; goodwill and long-lived asset valuations and associated impairment assessments; revenue reserves; share-based compensation valuations and income taxes.

Recent Accounting Pronouncements—Our Recent Accounting Pronouncements are described in our 2021 Annual Report on Form 10-K.

Pronouncements Adopted in Fiscal Year 2022

In August 2020, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“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 (“ASU 2020-06”), which simplifies the accounting for certain financial instruments with characteristics of liability and equity, including convertible instruments and contracts on an entity’s own equity. The standard reduces the number of models used to account for convertible instruments, removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, and requires the if-converted method for calculation of diluted earnings per share for all convertible instruments. We early adopted this standard effective October 2, 2021 using the modified retrospective approach transition method. Therefore, the condensed consolidated financial statements for the three months ended December 31, 2021 are presented under the new standard, while the comparative period presented is not adjusted and continues to be reported in accordance with the Company's historical accounting policy. Refer to Note 8 - Debt for the impact of adoption on our 2026 Convertible Notes (as defined below).

6

---

Pronouncements for Adoption in Subsequent Periods

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions to applying the guidance on contract modifications, hedge accounting, and other transactions, to simplify the accounting for transitioning from the London Interbank Offered Rate, and other interbank offered rates expected to be discontinued, to alternative reference rates. The guidance in this update was effective upon its issuance. If elected, the guidance is to be applied prospectively through December 31, 2022. We are currently evaluating the effect the potential adoption of this ASU will have on our consolidated financial statements, including, but not limited to, our Credit Agreement (defined below). For additional information regarding our Credit Agreement, refer to Note 8 - Debt.

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):

			Three Months Ended
			December 31, 2021						January 1, 2021
Revenue by Market:
Telecommunications			$	55,822					$	51,532
Industrial & Defense			73,146						61,618
Data Center			30,652						35,354
Total			$	159,620					$	148,504

			Three Months Ended
			December 31, 2021						January 1, 2021
Revenue by Geographic Region:
United States			$	74,426					$	63,982
China			36,063						42,376
Asia Pacific, excluding China (1)			30,650						21,773
Other Countries (2)			18,481						20,373
Total			$	159,620					$	148,504

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

(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 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 three months ended December 31, 2021 (in thousands, except percentage):

			December 31, 2021						October 1, 2021						$ Change						% Change
Contract liabilities			$	2,991					$	2,793					$	198					7		%

As of December 31, 2021 and October 1, 2021, $0.7 million and $0.9 million, respectively, of our contract liabilities, were recorded as other long-term liabilities on our balance sheet with the remainder recorded as accrued liabilities. During the three months ended December 31, 2021, we recognized net sales of $0.4 million that were included in the contract liabilities balance

7

---

as of the beginning of the period. The increase in contract liabilities during the three months ended December 31, 2021, as shown in the table above, was primarily related to deferral of revenue for invoiced products and services prior to when certain of our customers obtained control of the product and or services.

3. INVESTMENTS

All investments are short-term in nature and are invested in corporate bonds and commercial paper, and are classified as available-for-sale. 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):

			December 31, 2021
			Amortized Cost						Gross Unrealized Holding Gains						Gross Unrealized Holding Losses						Aggregate Fair Value
Corporate bonds			$	89,230					$	48					$	(617)					$	88,661
Commercial paper			115,706						—						(53)						115,653
Total short-term investments			$	204,936					$	48					$	(670)					$	204,314

			October 1, 2021
			Amortized Cost						Gross Unrealized Holding Gains						Gross Unrealized Holding Losses						Aggregate Fair Value
Corporate bonds			$	73,653					$	151					$	(171)					$	73,633
Commercial paper			114,718						21						(7)						114,732
Total short-term investments			$	188,371					$	172					$	(178)					$	188,365

    

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

			December 31, 2021			October 1, 2021
Less than one year			$	132,074		$	120,590
Over one year			72,240			67,775
Total available-for-sale investments			$	204,314		$	188,365

We have determined that the gross unrealized losses on available for sale securities as of December 31, 2021 and October 1, 2021 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.

Other Investments — As of December 31, 2021, 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 (“ASC”) 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 31, 2021 and October 1, 2021, the carrying value of this investment was $2.5 million and is classified as a long-term investment.

As of October 1, 2021, also included in long-term investments was a non-controlling investment of less than 10% in the outstanding equity of a private company, Ampere Computing Holdings LLC (“Ampere”), that was acquired in conjunction with our divestiture of our compute business during our fiscal year 2018. This investment’s carrying value was updated quarterly based on our proportionate share of the gains or losses, as well as any changes in Ampere's equity, utilizing the equity method.

As of October 1, 2021, the carrying value of this investment was $12.8 million. During the three months ended December 31, 2021 and January 1, 2021, we recorded our proportionate share of the losses on this investment of $3.3 million and $4.8 million, respectively, in Other income (expense), net in our condensed consolidated statements of operations.

On December 23, 2021, we sold our investment in Ampere to one of Ampere’s other limited liability company members, pursuant to the terms of a previously negotiated call option included in Ampere’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

8

---

approximately $9.5 million. As a result of this transaction, during the fiscal quarter ended December 31, 2021, we recorded a gain of $118.2 million in Other income (expense), net in our condensed consolidated statements of operations.

4. 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 31, 2021.

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

			December 31, 2021
			Fair Value						Active Markets for Identical Assets (Level 1)						Observable Inputs (Level 2)						Unobservable Inputs (Level 3)

Total assets measured at fair value			$	214,728					$	26,363					$	188,365					$	—

All common stock warrants were exercised during the three months ended January 1, 2021. During the three months ended January 1, 2021, the change in the fair value of the warrant liability, classified within Level 3 of the fair value hierarchy, consist of the following (in thousands):

			October 2, 2020						Net Realized Losses (Gains) Included in Earnings												Sales and Settlements												January 1, 2021

Term Loans

As of December 31, 2021, 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 31, 2021, 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 31, 2021, there are no minimum principal repayments on the Term Loans until fiscal year 2024 when the remaining principal balance of $120.8 million becomes due. The fair value of the Term Loans was estimated to be approximately $120.3 million as of December 31, 2021 and was determined using Level 2 inputs, including a quoted price from a financial institution.

As of December 31, 2021, approximately $0.8 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.

Prior to the adoption of ASU 2020-06 on October 2, 2021, the proceeds from the issuance of the 2026 Convertible Notes were allocated between the conversion feature recorded as equity and the liability for the notes themselves. The carrying amount of the liability component was calculated by measuring the fair value of a similar debt instrument that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the 2026 Convertible Notes. The difference of $80.7 million between the principal amount of the 2026 Convertible Notes and the liability component (the “Debt Discount”) was amortized to interest expense using the effective interest method over the term of the 2026 Convertible Notes until the adoption of ASU 2020-06. The equity component of the 2026 Convertible Notes was included in additional paid-in capital in the consolidated balance sheet and was not to be remeasured as long as it continued to meet the conditions for equity classification.

Prior to the adoption of ASU 2020-06, to account for the transaction costs related to the 2026 Convertible Notes, we allocated the total amount incurred of approximately $5.7 million to the liability and equity components of the 2026 Convertible Notes based on the proportion of the proceeds allocated to the debt and equity components. Issuance costs attributable to the liability component were approximately $4.7 million, were recorded as additional Debt Discount and were

12

---

amortized to interest expense over the contractual terms of the 2026 Convertible Notes. Issuance costs attributable to the equity component were approximately $1.0 million and were recorded as a reduction of additional paid in capital in stockholders’ equity.

In connection with the adoption of ASU 2020-06, 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 31, 2021, total interest expense for the 2026 Convertible Notes was $0.3 million.

The fair value of our 2026 Convertible Notes, including the conversion feature, was $529.3 million as of December 31, 2021 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 31, 2021; the full amount of $450.0 million is due in fiscal year 2026.

9. FINANCING OBLIGATION

On July 17, 2020, we entered into a power purchase agreement, which includes installation 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 construction and operation. As of December 31, 2021 and October 1, 2021, we capitalized $9.4 million and $8.9 million, respectively, to property and equipment, net and recorded a corresponding liability of $9.4 million and $8.9 million, respectively, primarily to Financing obligation, less current portion on our condensed consolidated balance sheet. The 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 7.7%, and the remaining future minimum payments are for power purchases. In total, we have $27.2 million in fixed payments associated with the power purchase agreement which is expected to commence in fiscal 2022 and has a 15-year term.

10. STOCKHOLDERS' EQUITY

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 31, 2021.

Common Stock Warrants—In March 2012, we issued warrants to purchase 1,281,358 shares of common stock for $14.05 per share. During the fiscal quarter ended January 1, 2021, the holders of the warrants made cashless exercises of 1,281,358 shares at an exercise price of $14.05 per share, resulting in the issuance of 857,631 shares of common stock.

During the three months ended January 1, 2021, we recorded the changes in the estimated fair value of the warrants in the accompanying statements of operations. See Note 4 - Fair Value for additional information. See Note 11 - Earnings (Loss) Per Share for impact of the common stock warrants on loss per share.

11. EARNINGS (LOSS) PER SHARE

The following table sets forth the computation for basic and diluted net income (loss) per share of common stock (in thousands, except per share data):

			Three Months Ended
			December 31, 2021						January 1, 2021
Numerator:
Net income (loss) attributable to common stockholders			$	138,827					$	(8,968)
Denominator:
Weighted average common shares outstanding-basic			69,400						67,756
Dilutive effect of stock options, restricted stock and restricted stock units			1,824						—
Weighted average common shares outstanding-diluted			71,224						67,756
Net income (loss) to common stockholders per share-Basic:			$	2.00					$	(0.13)
Net income (loss) to common stockholders per share-Diluted:			$	1.95					$	(0.13)

During the three months ended January 1, 2021, we had warrants outstanding which were measured at fair value. When calculating earnings per share, we are required to adjust for the dilutive effect of outstanding common stock equivalents, including adjustment to the numerator for the dilutive effect of contracts that must be settled in stock, including warrants. The table above excludes the effects of 2,004,621 shares for the three months ended January 1, 2021 of potential shares of common stock issuable upon exercise of stock options, warrants, and the vesting of restricted stock and restricted stock units, as applicable, as the inclusion would be antidilutive. The 2026 Convertible Notes do not have an impact on diluted earnings (loss) per share for the three months ended December 31, 2021.

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 fiscal quarter ended December 31, 2021.

13. SHARE-BASED COMPENSATION

Stock Plans

As of December 31, 2021, we had 5.4 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 1.4 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, as well as 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 31, 2021 are subject to accelerated vesting upon a change in control of the Company.

Incentive Stock Units

Outside of 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 31, 2021 and October 1, 2021, the fair value of outstanding awards was $9.2 million and $8.9 million, respectively, and the associated accrued compensation liability was $5.4 million and $6.2 million, respectively. During the

14

---

three months ended December 31, 2021 and January 1, 2021, we recorded an expense for ISU awards of $1.4 million and $3.0 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
			December 31, 2021						January 1, 2021
Cost of revenue			$	1,033					$	871
Research and development			3,599						3,554
Selling, general and administrative			5,317						5,706
Total share-based compensation expense			$	9,949					$	10,131

As of December 31, 2021, the total unrecognized compensation costs related to RSAs, RSUs and PRSUs was $71.2 million, which we expect to recognize over a weighted-average period of 2.3 years. As of December 31, 2021, total unrecognized compensation cost related to our Employee Stock Purchase Plan was $0.6 million.

Restricted Stock, Restricted Stock Units and Performance-Based Restricted Stock Unit Awards

A summary of stock award activity for the three months ended December 31, 2021 is as follows:

			Number of shares (in thousands)						Weighted- Average Grant Date Fair Value
Balance as of October 1, 2021			2,351						$	24.57
Granted			913						53.08
Vested and released			(969)						22.99
Forfeited, canceled or expired			(40)						27.54
Balance as of December 31, 2021			2,255						$	36.73

Stock awards that vested during the three months ended December 31, 2021 and January 1, 2021 had combined fair values of $69.9 million and $31.0 million, respectively, as of the vesting date. RSUs granted generally vest over a period of three or four years.

We granted 161,349 market-based PRSUs during the three months ended December 31, 2021, at a weighted average grant date fair value of $89.82 per share, or $14.5 million. Recipients may earn between 0% and 200% of the target number of shares granted, based on our achievement of total shareholder return in comparison to a selected group of peer companies over a three-year performance period. The fair value of these awards was estimated using a Monte Carlo simulation and share-based 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 significant assumptions used in the Monte Carlo simulation to calculate the fair value of these market-based PRSUs are as follows:

			Three Months Ended
			December 31, 2021
Grant date stock price			$	66.12
Average stock price at the start of the performance period			$	64.11
Risk free interest rate			0.8		%
Years to maturity			3.00
Expected volatility rate			57.8		%
Expected dividend yield			—

Stock Options

A summary of stock option activity for the three months ended December 31, 2021 is as follows (in thousands, except per share amounts and contractual term):

			Number of Shares						Weighted-Average Exercise Price per Share						Weighted-Average Remaining Contractual Term (in Years)						Aggregate Intrinsic Value
Options outstanding as of October 1, 2021			205						$	14.29
Exercised			(190)						14.15
Forfeited, canceled or expired			—						—
Options outstanding as of December 31, 2021			15						$	16.06					3.85						$	934
Options vested and exercisable as of December 31, 2021			15						16.06						3.85						934

Aggregate intrinsic value represents the difference between our closing stock price on December 31, 2021 and the exercise price of outstanding, in-the-money options. The total intrinsic value of options exercised was $11.0 million for the three months ended December 31, 2021 and was $0.3 million for the three months ended January 1, 2021.

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, 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
			December 31, 2021						January 1, 2021
Income tax expense			$	1,457					$	674
Effective income tax rate			1.0		%				(8.1)		%

The difference between the U.S. federal statutory income tax rate of 21% and our effective income tax rates for the three months ended December 31, 2021 and January 1, 2021 was primarily driven by the continuation of a full valuation allowance against any expense or benefit associated with income or losses in the U.S. and income taxed in foreign jurisdictions generally at lower tax rates and where a valuation allowance does not apply. The gain on the sale of our equity interest in Ampere during the three months ended December 31, 2021 has been offset by our NOL carryforwards.

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 asset including results of recent operations, future reversals of existing taxable temporary differences, projected future taxable income, and tax-planning strategies. We have determined that there was not sufficient objectively verifiable positive evidence to offset our significant negative objective evidence, therefore, we concluded that a full valuation allowance is appropriate for our U.S. deferred tax assets. Our negative objective evidence consists primarily of adjusted cumulative losses in the U.S. over the three-year period ended December 31, 2021.

Our deferred income tax asset balance as of December 31, 2021 and October 1, 2021 is primarily attributable to an initial $39.8 million deferred asset generated from an intra-entity transfer of a license for intellectual property during the fiscal quarter ended September 27, 2019. We expect this deferred tax asset to amortize over the life of the intellectual property.

There were no unrecognized tax benefits as of December 31, 2021 and October 1, 2021. 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 31, 2021, we did not make any accrual or payment of interest or penalties, nor did we make any payment.

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.

For information about our revenue in different geographic regions, based upon customer locations, see Note 2 - Revenue. Information about net property and equipment in different geographic regions is presented below (in thousands):

COVID-19 Impact

COVID-19 has spread throughout areas of the world where we operate and resulted in authorities implementing numerous measures to try to contain the virus. As a result of these measures and the spread of COVID-19, we have modified our business practices and may further modify our practices as required, or as we determine appropriate. While these measures, as well as other disruptions, have impacted our operations, the operations of our customers and those of our respective vendors and suppliers, such impacts did not, through the three months ended December 31, 2021, have a material impact on our consolidated operating results.

Given the significant continued economic uncertainty and volatility created by the pandemic, it is difficult to predict the nature and extent of impacts on the demand for our products. The continued spread of COVID-19 could cause a further economic slowdown or recession and could result in adverse impacts to our overall business, such as increased credit and collectability risks, adverse impacts on our supply chain, asset impairments, declines in the value of our financial instruments and adverse impacts on our capital resources. The degree to which the COVID-19 pandemic impacts our future business, financial condition, results of operations, liquidity and cash flows will depend on future developments, which are highly uncertain and cannot be accurately predicted, including the duration and spread of the outbreak, its severity, any resurgence of

COVID-19 cases, including as a result of variant strains of the underlying virus, actions taken to contain the virus or treat its impact, the availability and efficacy of vaccines against COVID-19, how quickly and to what extent normal operating conditions can resume, and the economic impact on local, regional, national and international markets.

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 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.

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, 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.

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 U.S. GAAP, requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. 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.

Due to the COVID-19 pandemic, there has been uncertainty and disruption in the global economy and financial markets. We are not aware of any specific event or circumstance that would require updates to our estimates or judgments or require us to revise the carrying value of our assets or liabilities as of the date of filing of this Quarterly Report on Form 10-Q with the SEC. These estimates may change as new events occur and additional information is obtained. Actual results could differ materially from these estimates under different assumptions or conditions.

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; goodwill and long-lived asset valuations and associated impairment assessments; revenue reserves; share-based compensation valuations and income taxes.

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

Comparison of the Three Months Ended December 31, 2021 to the Three Months Ended January 1, 2021

Revenue. Our revenue increased by $11.1 million, or 7.5%, to $159.6 million for the three months ended December 31, 2021, from $148.5 million for the three months ended January 1, 2021. The increase in revenue in the three months ended December 31, 2021 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
						December 31, 2021									January 1, 2021						% Change
Telecom			$			55,822						$			51,532						8.3		%
Industrial & Defense						73,146									61,618						18.7		%
Data Center						30,652									35,354						(13.3)		%
Total			$			159,620						$			148,504						7.5		%
Telecom						35.0		%							34.7		%
Industrial & Defense						45.8		%							41.5		%
Data Center						19.2		%							23.8		%
Total						100.0		%							100.0		%

In the three months ended December 31, 2021, our Telecom market revenue increased by $4.3 million, or 8.3%, compared to the three months ended January 1, 2021. The increase for the three months ended December 31, 2021 was primarily driven by an increase in RF and microwave products, for cable and video infrastructure, offset partially by a decrease in our China fronthaul market.

In the three months ended December 31, 2021, our I&D market revenue increased by $11.5 million, or 18.7%, compared to the three months ended January 1, 2021. The increase in the three months ended December 31, 2021 was primarily related to new program wins, expansion of our RF and microwave product lines and increases in legacy product sales.

---

In the three months ended December 31, 2021, our Data Center market revenue decreased by $4.7 million, or 13.3%, compared to the three months ended January 1, 2021. The decrease in the three months ended December 31, 2021 was primarily due to a decrease in sales of our high-performance analog Data Center products due to supply constraints.

Gross profit. Gross margin was 59.0% and 54.0% for the three months ended December 31, 2021 and January 1, 2021, respectively. Gross profit was $94.1 million and $80.3 million for the three months ended December 31, 2021 and January 1, 2021, respectively. Gross profit increased for the three months ended December 31, 2021 as compared to the three months ended January 1, 2021 primarily as a result of higher sales, favorable revenue mix, production efficiencies, as well as decreases in intangible amortization and warranty expense, partially offset by increases in employee-related costs.

Research and development. Research and development expense decreased by $1.5 million, or 4.0%, to $35.5 million, or 22.2% of our revenue, for the three months ended December 31, 2021, compared to $36.9 million, or 24.9% of our revenue, for the three months ended January 1, 2021. Research and development expense decreased in the three months ended December 31, 2021 primarily as a result of lower equipment rental charges and supplies and foundry costs.

Selling, general and administrative. Selling, general and administrative expense increased by $0.4 million, or 1.1%, to $31.6 million, or 19.8% of our revenue, for the three months ended December 31, 2021, compared to $31.3 million, or 21.0% of our revenue, for the three months ended January 1, 2021. Selling, general and administrative expense increased in the three months ended December 31, 2021 primarily due to an increase in employee-related and variable selling costs, offset by a decrease in intangible amortization.

Warrant liability expense. There was no warrant liability expense for the three months ended December 31, 2021, compared to an expense of $11.1 million for the three months ended January 1, 2021. The expense for the three months ended January 1, 2021 was driven by a change in the estimated fair value of common stock warrants, primarily driven by the increase in the underlying price of our common stock, which was recorded as a liability at fair value. During November 2020, all of the warrants were exercised and 857,631 shares of common stock were issued. For additional information refer to Note 10 - Stockholders' Equity to our Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q.

Interest expense, net. In the three months ended December 31, 2021, interest expense, net was $1.7 million, or 1.1% of our revenue, compared to $4.7 million, or 3.2% of our revenue, for the three months ended January 1, 2021. The decrease for the three months ended December 31, 2021 is primarily due to the adoption of ASU 2020-06 resulting in a lower effective interest rate on our long-term debt and the decrease in our long-term debt balance.

Other income (expense), net. In the three months ended December 31, 2021, other income, net was $114.9 million, or 72.0% of our revenue, compared to other expense, net of $4.5 million, or 3.0% of our revenue, for the three months ended January 1, 2021. The increase in the three months ended December 31, 2021 is primarily due to the gain on sale of our equity method investment of $118.2 million. See Note 3 - Investments 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
			December 31, 2021						January 1, 2021
Income tax expense			1,457						674
Effective income tax rate			1.0		%				(8.1)		%

Our estimated annual effective tax rate for the year ended September 30, 2022 is expected to be approximately 2%, adjusted for discrete taxation matters arising during the interim periods.

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 and the three months ended January 1, 2021 was primarily driven by the continuation of a full valuation allowance against any benefit or expense associated with losses or income in the U.S. and income taxed in foreign jurisdictions at generally lower tax rates, where we are not in a valuation allowance because it is expected that we will be in a taxable income position. The gain on the sale of our equity interest in Ampere during the three months ended December 31, 2021 has been offset by our NOL carryforwards. For additional information refer to Note 14 - Income Taxes to our Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q.

Adjustments to reconcile our net income to cash provided by operating activities primarily included a net gain of $114.9 million related to the sale of our equity method investment offset by equity method investment losses, depreciation and intangible amortization expense of $15.2 million and share-based compensation expense of $9.9 million. In addition, cash used in operating assets and liabilities was $16.3 million for the three months ended December 31, 2021, primarily driven by an increase in accounts receivable of $12.9 million and an increase in inventories of $5.8 million.

Our cash flow from operating activities for the three months ended January 1, 2021 of $34.8 million consisted of a net loss of $9.0 million, plus cash used in operating assets and liabilities of $1.3 million, plus adjustments to reconcile our net loss to cash provided by operating activities of $45.0 million. Adjustments to reconcile our net loss to cash provided by operating activities primarily included depreciation and intangible amortization expense of $18.2 million, share-based compensation expense of $10.1 million, a warrant liability expense of $11.1 million and a loss on an equity method investment of $4.8 million. In addition, cash used in operating assets and liabilities was $1.3 million for the three months ended January 1, 2021, primarily driven by an increase in accounts receivable of $9.3 million, offset by an increase in accounts payable of $5.4 million and a decrease in inventories of $2.6 million.

Cash Flow from Investing Activities

Our cash flow provided by investing activities for the three months ended December 31, 2021 of $105.7 million consisted primarily of proceeds from the sale of our equity method investment of $127.8 million, proceeds of $58.5 million for the sale and maturity of short-term investments, offset by purchases of $75.4 million of short-term investments and capital expenditures of $5.1 million. For additional information on the sale of our equity method investment, see Note 3 - Investments to our Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q.

Our cash flow used in investing activities for the three months ended January 1, 2021 of $24.8 million consisted primarily of purchases of $82.0 million of short-term investments, capital expenditures of $2.9 million, offset by proceeds of $60.2 million related to the sale and maturity of short-term investments.

Cash Flow from Financing Activities

During the three months ended December 31, 2021, our cash used in financing activities of $22.9 million was primarily related to $27.8 million of repurchases of common stock associated with employee tax withholdings on vested equity awards, partially offset by $5.1 million of proceeds from stock option exercises and employee stock purchases.

During the three months ended January 1, 2021, our cash used in financing activities of $11.5 million was primarily related to $11.8 million of repurchases of stock associated with employee tax withholdings on vested equity awards and $1.7 million of payments on long-term debt offset by $2.4 million of proceeds from stock option exercises and employee stock purchases.

Liquidity

As of December 31, 2021, we held $273.4 million of cash and cash equivalents, primarily deposited with financial institutions, as well as $204.3 million of liquid short-term investments. During the three months ended December 31, 2021, our revolving credit facility, which had $160.0 million in borrowing capacity, expired and is no longer available. 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 31, 2021, cash held by our indefinitely reinvested foreign subsidiaries was $32.1 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 31, 2021, 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 and commercial paper. 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 the increase or decrease in the amount of interest expense we must pay on the outstanding debt under the Credit Agreement. The interest rates 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 31, 2021, 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. The interest rates on our 2026 Convertible Notes are fixed and therefore not subject to interest rate risk.

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. Increases 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. Conversely, decreases in the value of the U.S. dollar relative to other currencies could result in our products being more expensive to certain customers and could reduce or delay orders, or otherwise negatively affect how they 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 31, 2021.

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.
