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 2, 20201, 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 2, 20201, 2021 consolidated financial statements, which were included in our Annual Report on Form 10-K for our fiscal year ended October 2, 20201, 2021 filed with the SEC on November 18, 202015, 2021 (the “2020“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 20202021 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 yearyears 2022 and 2021 includeseach include 52 weeks and fiscal year 2020 included 53 weeks. To offset the effect of holidays, for fiscal years in which there are 53 weeks, we include the extra week arising in such fiscal years in the first fiscal quarter. Our first fiscal quarter ended January 1, 2021 included 13 weeks and the first fiscal quarter ended January 3, 2020 had 14 weeks.
Use of Estimates—The preparation of condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities during the reporting periods, the reported amounts of revenue and expenses during the reporting periods, and the disclosure of contingent assets and liabilities at the date of the financial statements. On an ongoing basis, we base estimates and assumptions on historical experience, currently available information and various other factors that management believes to be reasonable under the circumstances. Actual results may differ materially from these estimates and assumptions. The accounting policies which our management believes involve the most significant application of judgment or involve complex estimation, are inventories and associated reserves; 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 the 2020our 2021 Annual Report on Form 10-K.
Pronouncements Adopted in Fiscal Year 2021
On the first day of fiscal year 2021, we adopted Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This ASU introduces a new accounting model known as Credit Expected Credit Losses (“CECL”), which requires earlier recognition of credit losses. The CECL model utilizes a lifetime expected credit loss measurement objective for the recognition of credit losses for receivables at the time the financial asset is originated or acquired, replacing the current incurred loss methodology that delays recognition of credit losses until a probable loss has been incurred. There are other provisions within the standard affecting how impairments of other financial assets may be recorded and presented, as well as expanded disclosures. There was no impact to our unaudited condensed consolidated financial statements from the adoption of this guidance.
We generate accounts receivable from customers and they are classified as short-term. We monitor collections and maintain a provision for expected credit losses based on historical trends, current conditions, and relevant forecasted information, in addition to provisions established for any specific collection issues that have been identified. As of April 2, 2021, our allowance for expected credit losses was less than $0.1 million.
Our investments in debt securities, which are classified as available-for-sale, are further disclosed in Note 3, Investments. As of April 2, 2021, our available-for-sale debt securities had gross unrealized losses of $0.2 million, which we believe to be temporary, and therefore there is no allowance for credit losses recorded in our condensed consolidated statement of operations.

2022
In January 2017,August 2020, the Financial Accounting Standards Board (the “FASB”) issued ASU 2017-04,Accounting Standards Update (“ASU”) 2020-06, Intangibles - GoodwillDebt—Debt with Conversion and Other (Topic 350)Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Simplifying the TestAccounting for Goodwill Impairment. Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”)ASU 2017-04, which simplifies the subsequent measurementaccounting for certain financial instruments with characteristics of goodwill by eliminating Step 2 fromliability and equity, including convertible instruments and contracts on an entity’s own equity. The standard reduces the goodwill impairment test. Instead, a one-step quantitative impairment test calculates goodwill impairment asnumber of models used to account for convertible instruments, removes certain settlement conditions that are required for equity contracts to qualify for the excessderivative scope exception, and requires the if-converted method for calculation of the carrying value of a reporting unit over its fair value, up to the carrying value of the goodwill. This ASU should be applied on a prospective basis. diluted earnings per share for all convertible instruments. We early adopted this ASU instandard effective October 2, 2021 using the first quarter of fiscal year 2021 andmodified retrospective approach transition method. Therefore, the adoption of this update did not have an impact on our 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 related disclosures.
In August 2018, the FASB issued ASU 2018-15, Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, to provide additional guidance on the accounting for costs of implementing cloud computing arrangements that are service contracts, and requiring customers in such arrangements to follow the guidance in Subtopic 350-40. The amendments in this update require the capitalization of implementation costs during the application development stage of such hosting arrangements and amortization of the expense over the term of the arrangement beginning when the module or component of the hosting arrangement is ready for its intended use. Capitalized implementation costs and amortization thereof are also requiredcontinues to be classifiedreported in the same line item in the statements of financial position, operations and cash flows associatedaccordance with the hosting service fees. We adopted this ASU inCompany's historical accounting policy. Refer to Note 8 - Debt for the first quarterimpact of fiscal year 2021 and selected prospective application to all implementation costs incurred after the adoption date. The adoption of this update did not have an impact on our condensed consolidated financial statements and related disclosures.2026 Convertible Notes (as defined below).

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; ifissuance. If elected, itthe 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.Credit Agreement (defined below). For additional information regarding our credit agreement, refer to Note 8 - Debt.
In August 2020, the FASB issued 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, 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. The standard is effective for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2021. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. We are evaluating the impact to our financial statements and expect that the resulting impact will be to reclassify the equity component of our 2026 Convertible Notes (as defined below) from additional paid-in capital to long-term debt, up to the par value, and a reduction of our reported interest expense on our 2026 Convertible Notes to their stated 0.25% percent coupon rate on a prospective basis. For additional information regarding our debt,Credit Agreement, refer to Note 8 - Debt.

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 sixthree months ended April 2,December 31, 2021 (in thousands, except percentage):

As of April 2,December 31, 2021 and October 2, 2020, $4.81, 2021, $0.7 million and $3.5$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 and six months ended April 2,December 31, 2021, we recognized net sales of $0.7$0.4 million and $6.0 million, respectively, that were included in the contract liabilities balance

as of the beginning of the period. The decreaseincrease in contract liabilities during the sixthree months ended April 2,December 31, 2021, as shown in the table above, was primarily related to recognition of license revenue, partially offset by the deferral of revenue for invoiced products and services prior to when certain of our customers obtained control of the product and or services.

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"(“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 April 2,December 31, 2021 and October 2, 2020,1, 2021, the carrying value of this investment was $2.5 million.million and is classified as a long-term investment.

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 and six months ended April 2,December 31, 2021.

Term Loans
As of April 2,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, (“Goldman Sachs”), 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 April 2,December 31, 2021, the Credit Agreement consisted of term loans with an initial aggregate principal amount of $700.0 million (the “Term Loans”) and a revolving credit facility with an aggregate borrowing capacity of $160.0 million (the “Revolving Facility”). The Revolving Facility will mature in November 2021 and the Term Loansthat 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%.

During the fiscal quarter ended April 2, 2021, we repaid $494.3 million in principal under the Term Loans using $394.3 million of the net proceeds from our 2026 Convertible Notes offering, described below, as well as existing cash and short-term investments. In connection with this prepayment, we wrote off unamortized deferred financing costs and recognized a loss on extinguishment of debt of $3.8 million for the three and six months ended April 2, 2021. The $3.8 million is a non-cash adjustment to income from operations in our condensed consolidated statements of cash flows for the six months ended April 2, 2021.
As of April 2,December 31, 2021, there are no minimum principal repayments on the Term Loans until fiscal year 2024 when the remaining principal balance of $170.1$120.8 million becomes due. The fair value of the Term Loans was estimated to be approximately $168.4$120.3 million as of April 2,December 31, 2021 and was determined using Level 2 inputs, including a quoted price from a financial institution.
As of April 2,December 31, 2021, approximately $1.7$0.8 million of deferred financing costs remain unamortized of which $1.5 million is related to the Term Loans and is recorded as a direct reduction of the recognized debt liabilities in our accompanying condensed consolidated balance sheet, and $0.2 million is related to the Revolving Facility and is recorded in other long-term assets in our accompanying condensed consolidated balance sheet.
The Term Loans and Revolving Facility 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.
In the event that we divest a business, the net cash proceeds of the divestment are generally required, subject to certain exceptions, to be applied to repayment of outstanding Term Loans except to the extent we reinvest such proceeds in assets useful for our business within 18 months of receiving the proceeds. If we enter into a binding agreement to reinvest such proceeds within 18 months of receiving them, we have until the later of 18 months following our receipt of the proceeds and six months following the date of such agreement to complete the reinvestment.

As of April 2, 2021, we had $160.0 million of borrowing capacity under our Revolving Facility, of which we may borrow up to $50.0 million without being subject to certain financial covenants.

2026 Convertible Notes
On March 25, 2021, we issuedissued 0.25% convertible senior notes due in fiscal year 2026, pursuant to an Indentureindenture dated as of such date (the Indenture“Indenture”), between the Company and U.S. Bank National Association, as trustee, with an aggregate principal amount of $400.0 million (the 2026“Initial Notes”), and on April 6, 2021, we issued an additional $50.0 million aggregate principal amount (the “Additional Notes”) (together, the “2026 Convertible NotesNotes”), including an option for the initial purchaser. The aggregate principal balance of the 2026 Convertible Notes to purchase up to an additional $60.0 million principal amount of the 2026 Convertible Notes in a private placement to qualified institutional buyers pursuant to Rule144A under the Securities Act of 1933, as amended.is $450.0 million. The 2026 Convertible Notes willwill 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 5 business day period after any 5 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 willare 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,
14


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.
ThePrior to the adoption of ASU 2020-06 on October 2, 2021, the proceeds from the issuance of the 2026 Convertible Notes have beenwere 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. TheThe difference of $71.8$80.7 million between the principal amount of the 2026 Convertible Notes and the liability component (the “Debt Discount”) iswas amortized to interest expense using the effective interest method over the term of the 2026 Convertible Notes.Notes until the adoption of ASU 2020-06. The equity component of the 2026 Convertible Notes iswas included in additional paid-in capital in the consolidated balance sheet and iswas not to be remeasured as long as it continuescontinued to meet the conditions for equity classification.
In accountingPrior 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 $5.1$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 $4.2$4.7 million,, were recorded as an additional Debt Discount and are were
12


amortized to interest expense over the contractual terms of the 2026 Convertible Notes. Issuance costs attributable to the equity component were approximately $0.9$1.0 million and were recorded as a reduction of additional paid in capital in stockholders’ equity.
ForIn connection with the threeadoption of ASU 2020-06, we reclassified $72.2 million, consisting of $73.1 million of principal and six months ended Aprilissuance 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 included inas required under the legacy accounting guidance. Under ASU 2020-06, we will no longer incur non-cash interest expense was $0.3 million andrelated 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 $400.0529.3 million as of April 2,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 0no future minimum principal payments under the notes as of April 2,December 31, 2021; the full amount of $400.0$450.0 million is due in fiscal year 2026.
For additional information regarding our debt, specifically the April 6, 2021 issuance of an additional $50 million aggregate principal amount of our 2026 Convertible Notes, refer to Note 18 - Subsequent Events.
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 April 2,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, Summit Partners Private Equity Fund VII-A, L.P., Summit Partners Private Equity Fund VII-B, L.P., Summit Investors I, LLC, Summit Investors I (UK), L.P. and Mainsail Partners II, L.P.the holders of the warrants made cashless exercises of warrants for 1,281,358 shares at an exercise price of $14.05 per share, resulting in the issuance of 857,631 shares of common stock. We received no proceeds from the exercise of warrants.
During the sixthree months ended April 2,January 1, 2021, and the three and six months ended April 3, 2020, 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 related to the fair value of our warrant liability.information. See Note 1011 - Earnings (Loss) Per Share for impact of the common stock warrants on loss per share.

During the three and six months ended April 3, 2020,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. During the three and six months ended April 3, 2020, we adjusted the numerator by the warrant gains of $8.6 million and $4.6 million, respectively, and the denominator by the incremental shares of 562,567 and 545,578, respectively. The table above excludes the effects of 174,989 shares for the six months ended April 2, 2021, and 1,009,830 shares and 886,6712,004,621 shares for the three and six months ended April 3, 2020, respectively,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 EPSearnings (loss) per share for the three and six months ended April 2,December 31, 2021.
11.12. 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 April 2,December 31, 2021.
12. RESTRUCTURINGS
We have periodically implemented restructuring actions in connection with broader plans to reduce staffing, reduce our internal manufacturing footprint and generally reduce operating costs. The restructuring expenses are primarily comprised of direct and incremental costs related to headcount reductions including severance and outplacement fees for the terminated employees, as well as facility closure costs.
There were no restructuring charges incurred during the three and six months ended April 2, 2021. The following is a summary of the restructuring charges incurred during the three and six months ended April 3, 2020 (in thousands):

16


development activities for one of our product lines and no longer investing in the design and development of optical modules and subsystems for Data Center applications (the “2019 Plan”). We incurred restructuring charges in the three and six months ended April 3, 2020 under the 2019 Plan, as shown above.

13. SHARE-BASED COMPENSATION
Stock Plans
As of April 2,December 31, 2021, we had 6.05.4 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 1.51.4 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"(“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). 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. Options granted under the 2012 Plan primarily vestvested based on certain market-based and performance-based criteria. Options grantedcriteria and generally have a term of four years to seven years. Certain of the share-based awards granted and outstanding as of April 2,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. 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):

The difference between the U.S. federal statutory income tax rate of 21% and our effective income tax rates for the three and six months ended April 2,December 31, 2021 and April 3, 2020January 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 April 2,December 31, 2021.
Our deferred income tax asset balance as of April 2,December 31, 2021 and October 2, 20201, 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.
The balance of theThere were no unrecognized tax benefits was $0.3 million as of April 2,December 31, 2021 and October 2, 2020.1, 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 April 2,December 31, 2021, we did not make any accrual or payment of interest or penalties, nor did we make any payment, because we believe our $0.3 million accrual would cover any additional amounts due.payment.

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 for the periods presented.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 suppliers,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

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 semiconductorsemiconductor-based products that we sell to customers through our direct sales organization, our network of independent sales representatives and our distributors.
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 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.
21


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; fair value of convertible debt; revenue reserves; share-based compensation valuations and income taxes.
Significant management judgment is required in our valuation of long-lived asset groups when assessing for potential impairment. These analyses are based on the creation of forecasts of future operating results that are used in the valuation, including estimation of (i) future cash flows, (ii) the long-term rate of growth for our business, (iii) 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 is used to determine the discount rate. It is possible that these forecasts may change and our projections included in our forecasts of future results may prove to be inaccurate. If our actual results, or the forecasts and estimates used in future impairment analyses, are lower than the original estimates used to assess the recoverability of these assets, we could incur impairment charges. Our forecasts and the value of our long-lived asset groups could be adversely affected by, but not limited to, a change in strategy, the outcome of development activities, a significant slowdown in our primary markets, the semiconductor industry or worldwide economy, or a decline in the valuation of technology company stocks, including the valuation of our common stock.
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 20202021 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.

Liquidity
As of April 2,December 31, 2021, we held $105.5$273.4 million of cash and cash equivalents, primarily deposited with financial institutions, as well as $162.6$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 April 2,December 31, 2021, cash held by our indefinitely reinvested foreign subsidiaries was $23.4$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. As of April 2, 2021, we had $160.0 million in borrowing capacity under our Revolving Facility, of which we may borrow up to $50.0 million without being subject to certain financial covenants.
We plan to use our remaining available cash and cash equivalents and short-term investments and, as deemed appropriate, our borrowing capacity under our Revolving Facility 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 and borrowing availability under the Revolving Facility 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.

Recent Accounting Pronouncements
See 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 for information about recent accounting pronouncements.
Off-Balance Sheet Arrangements
We did not have any off-balance sheet arrangements as of April 2, 2021.
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 and Revolving Facility 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 April 2,December 31, 2021, we had $170.1$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 $1.7$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 April 2,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.

ITEM 1. LEGAL PROCEEDINGS
See Note 1112 - Commitments and Contingencies to our Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q for information about our legal proceedings.
ITEM 1A. RISK FACTORS
Our business involves a high degree of risk.  In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the factors discussed in Part I, “Item 1A. Risk Factors” in our 20202021 Annual Report on Form 10-K, which could materially affect our business, financial condition or future results. As of the date of this Quarterly Report on Form 10-Q, there have been no material changes in any of the risk factors described in our 20202021 Annual Report on Form 10-K, except as noted below.

Risks Relating to our 2026 Convertible Notes

Servicing our debt, including the 2026 Convertible Notes, requires a significant amount of cash, and we may not have sufficient cash flow from our business to pay our indebtedness.

Our ability to make payments of the principal of, to pay interest on, or to refinance, the 2026 Convertible Notes, or to make cash payments in connection with any conversion of the 2026 Convertible Notes depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to service the 2026 Convertible Notes or other indebtedness and make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring indebtedness or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance the 2026 Convertible Notes or our other indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations.

Provisions in indenture governing the 2026 Convertible Notes may delay or prevent an otherwise beneficial business combination.

The terms of the 2026 Convertible Notes require us to repurchase the 2026 Convertible Notes in the event of a “fundamental change” as defined under the indenture governing the 2026 Convertible Notes. A fundamental change of our Company would trigger an option of the holders of the 2026 Convertible Notes to require us to repurchase the 2026 Convertible Notes. In addition, if a make-whole fundamental change occurs prior to the maturity date of the 2026 Convertible Notes, we will in some cases be required to increase the conversion rate for a holder that elects to convert its 2026 Convertible Notes. Furthermore, the indenture that governs the 2026 Convertible Notes prohibits us from engaging in certain mergers or acquisitions unless, among other things, the surviving entity assumes our obligations under the 2026 Convertible Notes. This may have the effect of delaying or preventing an acquisition of our Company that could be beneficial to investors.

We may not have the ability to raise the funds necessary to settle conversions of the 2026 Convertible Notes in cash or to repurchase the 2026 Convertible Notes upon a fundamental change and our debt may limit our ability to pay cash upon conversion or repurchase of the 2026 Convertible Notes.

Holders of the 2026 Convertible Notes have the right to require us to repurchase their 2026 Convertible Notes upon the occurrence of a fundamental change at a purchase price equal to 100% of the principal amount of the 2026 Convertible Notes to be repurchased, plus accrued and unpaid interest, if any, to, but not including, the fundamental change repurchase date. In addition, unless we elect to deliver solely shares of our common stock upon conversion, we will be required to make cash payments in respect of the 2026 Convertible Notes being converted. However, we may not have enough available cash or be able to obtain financing at the time we are required to make purchases of the 2026 Convertible Notes, and our failure to do so would constitute a default under the indenture governing the 2026 Convertible Notes. In addition, our ability to repurchase the 2026 Convertible Notes or to pay cash upon conversion of the 2026 Convertible Notes could be limited by law, by regulatory authority or by agreements that will govern our future indebtedness. A default under the indenture governing the 2026 Convertible Notes or the fundamental change itself could also lead to a default under agreements governing our existing or future indebtedness.
