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, 2020 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, 2020 consolidated financial statements, which were included in our Annual Report on Form 10-K for our fiscal year ended October 2, 2020 filed with the SEC on November 18, 2020 (the “2020 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 2020 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 year 2021 includes 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; fair value of convertible debt; revenue reserves; share-based compensation valuations and income taxes.

Recent Accounting Pronouncements—Our Recent Accounting Pronouncements are described in the 2020 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 July 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 July 2, 2021, our available-for-sale debt securities had gross unrealized losses of $0.1 million, which we believe to be temporary, and therefore there is no allowance for credit losses recorded in our condensed consolidated statement of operations.

In January 2017, the Financial Accounting Standards Board (the “FASB”) issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. ASU 2017-04 simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Instead, a one-step quantitative impairment test calculates goodwill impairment as the excess 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. We adopted this ASU in the first quarter of fiscal year 2021 and the adoption of this update did not have an impact on our condensed consolidated financial statements 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 required to be classified in the same line item in the statements of financial position, operations and cash flows associated with the hosting service fees. We adopted this ASU in the first quarter 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.

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.

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) of $79.7 million from additional paid-in capital to long-term debt, up to the par value, with the remainder to accumulated deficit. On a prospective basis, there will be a reduction of our reported interest expense on our 2026 Convertible Notes to their stated 0.25% coupon rate. For additional information regarding our debt, refer to Note 8 - Debt.

2. REVENUE

Disaggregation of Revenue

Contract Balances

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

The following table presents the changes in contract liabilities during the nine months ended July 2, 2021 (in thousands, except percentage):


	July 2, 2021		October 2, 2020		$ Change		% Change
Contract liabilities	$	6,349	$	9,861	$	(3,512)	(36)	%

As of July 2, 2021 and October 2, 2020, $4.6 million and $3.5 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 nine months ended July 2, 2021, we recognized net sales of $0.1 million and $6.1 million, respectively, that were included in the contract liabilities balance as of the beginning of the period. The decrease in contract liabilities during the nine months ended July 2, 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.

Less than one year	$	106,885
Over one year	57,881
Total available-for-sale investments	$	164,766

Available-for-sale investments are reported at fair value and, as such, their associated unrealized gains and losses are reported as a separate component of stockholders’ equity within accumulated other comprehensive income.

Other Investments — As of July 2, 2021, we held two non-marketable equity investments classified as long-term investments, including an investment in a Series B preferred stock ownership 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 July 2, 2021 and October 2, 2020, the carrying value of this investment was $2.5 million.

Also included in long-term investments, is a non-controlling investment of less than 10% in the outstanding equity of a private company, Ampere Computing Holdings LLC (“Compute”), that was acquired in conjunction with our divestiture of the Compute business during our fiscal year 2018. This investment’s carrying value is updated quarterly based on our proportionate share of the gains or losses, as well as any changes in Compute's equity, utilizing the equity method. We are a passive investor with limited rights and are not engaged in the operating activities of Compute. One of Compute’s other limited liability company members has a call option right to purchase all of our equity on or before October 27, 2021 and prior to 45 days thereafter, at either fair market value at the time of exercise or for a maximum fixed price of approximately $128 million which may not represent fair market value. We have no control and cannot predict when or if this call option will be exercised, whether our equity position will become liquid or whether it will become further diluted due to capital structure changes to Compute. Any gain or loss from an exercise of a call option would be recognized at the time it is realized.

During the three and nine months ended July 2, 2021, we recorded net losses of $2.0 million and $0.3 million, respectively, associated with this investment as other expense in our condensed consolidated statements of operations. The nine months ended July 2, 2021 include a non-cash gain of $9.8 million associated with changes in Compute's equity. During the three and nine months ended July 3, 2020, we recorded losses of $4.6 million and $13.6 million, respectively. As of July 2, 2021 and October 2, 2020, the carrying value of this investment was $14.9 million and $15.2 million, respectively.

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 nine months ended July 2, 2021.

Term Loans

As of July 2, 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 July 2, 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 Loans 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 nine months ended July 2, 2021, we repaid $543.6 million in principal under the Term Loans using $443.6 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 these prepayments, during the three and nine months ended July 2, 2021, we expensed unamortized deferred financing costs and recognized losses on extinguishment of debt of $0.6 million and $4.4 million, respectively. The loss on extinguishment is a non-cash adjustment to cash flows from operating activities in our condensed consolidated statements of cash flows for the nine months ended July 2, 2021.

As of July 2, 2021, there are no minimum principal repayments on the Term Loans until 2024 when the remaining principal balance of $120.8 million becomes due. The fair value of the Term Loans was estimated to be approximately $120.6 million as of July 2, 2021 and was determined using Level 2 inputs, including a quoted price from a financial institution.

As of July 2, 2021, approximately $1.1 million of deferred financing costs remain unamortized, of which $1.0 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 $0.1 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.

As of July 2, 2021, we had $160.0 million of borrowing capacity under our Revolving Facility.

2026 Convertible Notes

On March 25, 2021, we issued 0.25% convertible senior notes due in 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”). No additional 2026 Convertible Notes will be issued and the aggregate principal balance 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.

Upon conversion of the 2026 Convertible Notes, we will 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 (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.

The proceeds from the issuance of the 2026 Convertible Notes have been 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”) is amortized to interest expense using the effective interest method over the term of the 2026 Convertible Notes. The equity component of the 2026 Convertible Notes is included in additional paid-in capital in the consolidated balance sheet and is not remeasured as long as it continues to meet the conditions for equity classification.

In accounting 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 are 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 are recorded as a reduction of additional paid in capital in stockholders’ equity.

For the three and nine months ended July 2, 2021, accretion of the Debt Discount included in interest expense was $3.6 million and $3.9 million, respectively, and as of July 2, 2021, the unamortized discount on the 2026 Convertible Notes was $76.8 million. For the three and nine months ended July 2, 2021, total interest expense for the 2026 Convertible Notes was $3.9 million and $4.2 million, respectively.

The fair value of our 2026 Convertible Notes, including the conversion feature, was $469.2 million as of July 2, 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 July 2, 2021; the full amount of $450.0 million is due in fiscal 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. Despite not being the legal owner, for accounting purposes only we are deemed to be the owner of the power generator during construction since we control the use of the asset. As of July 2, 2021, we capitalized $6.6 million to property and equipment, net and recorded a corresponding liability of $6.6 million 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%. The remaining future minimum payments of $10.4 million will be accrued and expensed as incurred.

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 July 2, 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. 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.

During the nine months ended July 2, 2021 and the three and nine months ended July 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. 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				Nine Months Ended
	July 2, 2021		July 3, 2020		July 2, 2021		July 3, 2020
Numerator:


Net income (loss) attributable to common stockholders	$	15,005	$	(24,982)	$	20,844	$	(63,570)
Denominator:
Weighted average common shares outstanding-basic	68,732		66,796		68,331		66,512
Dilutive effect of stock options, restricted stock and restricted stock units	2,148		—		1,951		—
Weighted average common shares outstanding-diluted	70,880		66,796		70,282		66,512

Net loss to common stockholders per share-Basic:	$	0.22	$	(0.37)	$	0.31	$	(0.96)
Net loss to common stockholders per share-Diluted:	$	0.21	$	(0.37)	$	0.30	$	(0.96)

During the nine months ended July 2, 2021 and three and nine months ended July 3, 2020, 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 116,659 shares for the nine months ended July 2, 2021, and 1,766,561 shares and 1,543,686 shares for the three and nine months ended July 3, 2020, respectively, 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 and nine months ended July 2, 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 July 2, 2021.

13. 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 nine months ended July 2, 2021. The following is a summary of the restructuring charges incurred during the three and nine months ended July 3, 2020 (in thousands):


	Three Months Ended		Nine Months Ended
	July 3, 2020		July 3, 2020
Employee related expenses and adjustments	$	(761)	$	787
Facility related expenses	207		707
Total restructuring charges	$	(554)	$	1,494

2019 Plan

During the fiscal quarter ended June 28, 2019, we committed to a plan designed to strategically realign, streamline and improve certain of our business and operations, including reducing our workforce by approximately 250 employees, exiting six development facilities in France, Japan, the Netherlands, Florida, Massachusetts and Rhode Island, reducing certain 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 nine months ended July 3, 2020 under the 2019 Plan, as shown above. This action was completed during fiscal 2020 and we do not expect to incur further costs. The remaining charges will be paid during fiscal 2021.

Details of the 2019 Plan accrual activity for the nine months ended July 2, 2021 are as follows (in thousands):


	Employee-Related Expense (1)		Facility-Related Expense (2)		Total
Balance as of October 2, 2020	$	235	$	26	$	261
Charges and adjustments	—		—		—
Charges paid/settled/other	2		(26)		(24)
Balance as of July 2, 2021	$	237	$	—	$	237

(1) Primarily includes severance charges associated with the reduction of our workforce in certain facilities.

(2) Primarily includes activities associated with the closure of certain facilities, including any associated asset impairments and contract termination costs.

14. SHARE-BASED COMPENSATION

Stock Plans

As of July 2, 2021, we had 6.0 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 1.5 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. 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). 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 vested based on certain market-based and performance-based criteria. Options granted generally have a term of four years to seven years. Certain of the share-based awards granted and outstanding as of July 2, 2021 are subject to accelerated vesting upon a change in control of the Company.

Share-Based Compensation

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


	Three Months Ended				Nine Months Ended
	July 2, 2021		July 3, 2020		July 2, 2021		July 3, 2020

Total share-based compensation expense	$	8,141	$	8,495	$	26,841	$	26,921

As of July 2, 2021, the total unrecognized compensation costs related to RSAs, RSUs and PRSUs was $47.1 million, which we expect to recognize over a weighted-average period of 2.1 years. As of July 2, 2021, total unrecognized compensation cost related to our Employee Stock Purchase Plan was $0.8 million.

Stock Options

A summary of stock option activity for the nine months ended July 2, 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 2, 2020	325	$	15.12

Exercised	(60)	16.30

Options vested and exercisable as of July 2, 2021	265	14.85		6.73	12,637

Aggregate intrinsic value represents the difference between our closing stock price on July 2, 2021 and the exercise price of outstanding, in-the-money options. The total intrinsic value of options exercised was $0.4 million and $2.5 million for the three and nine months ended July 2, 2021, respectively, and was $0.7 million and $1.0 million for the three and nine months ended July 3, 2020, respectively.

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

A summary of stock award activity for the nine months ended July 2, 2021 is as follows:


	Number of shares (in thousands)	Weighted- Average Grant Date Fair Value
Balance as of October 2, 2020	2,788	$	20.84
Granted	958	30.97
Vested and released	(1,284)	21.37
Forfeited, canceled or expired	(106)	25.72
Balance as of July 2, 2021	2,356	$	24.45

Stock awards that vested during the nine months ended July 2, 2021 and July 3, 2020 had combined fair values of $64.0 million and $18.7 million, respectively, as of the vesting date. RSUs granted generally vest over a period of three or four years.

15. 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						Nine Months Ended
	July 2, 2021			July 3, 2020			July 2, 2021			July 3, 2020
Income tax expense	$	482		$	1,750		$	3,349		$	4,716
Effective income tax rate	3.1		%	(7.5)		%	13.8		%	(8.0)		%

The difference between the U.S. federal statutory income tax rate of 21% and our effective income tax rates for the three and nine months ended July 2, 2021 and July 3, 2020 was primarily driven by the continuation of a full valuation allowance against any benefit associated with losses in the U.S. and income taxed in foreign jurisdictions generally at lower tax rates and where a valuation allowance does not apply.

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 July 2, 2021.

Our deferred income tax asset balance as of July 2, 2021 and October 2, 2020 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 the unrecognized tax benefits was $0.3 million as of July 2, 2021 and October 2, 2020. 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 July 2, 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.

16. SUPPLEMENTAL CASH FLOW INFORMATION

The following is a summary of supplemental cash flow information for the periods presented (in thousands):


	Nine Months Ended
	July 2, 2021		July 3, 2020

Cash paid for income taxes	$	1,378	$	309
Non-cash activities:
Operating lease right-of-use assets obtained in exchange for new lease liabilities	$	3,447	242
Financing lease assets obtained in exchange for new lease liabilities	$	—	$	586
Non-cash capital expenditures	$	7,065	$	533

During the nine months ended July 2, 2021, we capitalized $6.6 million of non-cash costs to property and equipment associated with construction of a power generator that are paid by our service provider and is included in non-cash capital expenditures above. See Note 9 - Financing Obligation.

17. 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 use of financial information for the purposes of assessing performance and making operating decisions. In evaluating financial performance and making operating decisions, the chief operating decision maker primarily uses consolidated metrics. We evaluate this assessment on an ongoing basis as facts and circumstances change and as of July 2, 2021 there were no changes to our conclusion.

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):

Overview

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

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 have a material impact on our consolidated operating results for the periods presented.

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, 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.

For additional information on risk factors that could impact our future results, please refer to the section entitled “Risk Factors” in this Quarterly Report on Form 10-Q and the 2020 Annual Report on Form 10-K.

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 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.

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 2020 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.

Revenue. Our revenue increased by $15.4 million, or 11.2%, to $152.6 million for the three months ended July 2, 2021, from $137.3 million for the three months ended July 3, 2020, and our revenue increased by $68.9 million, or 18.0%, to $451.7 million for the nine months ended July 2, 2021, from $382.8 million for the nine months ended July 3, 2020. The increase in revenue in the three and nine months ended July 2, 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								Nine Months Ended
		July 2, 2021			July 3, 2020		% Change			July 2, 2021			July 3, 2020		% Change

In the three months ended July 2, 2021, our Telecom market revenue decreased by $8.8 million, or 15.5%, compared to the three months ended July 3, 2020. In the nine months ended July 2, 2021, our Telecom market revenue decreased by $12.3 million, or 8.0%, compared to the nine months ended July 3, 2020. The decrease for the three and nine months ended July 2, 2021 was primarily driven by a decrease in carrier-based optical semiconductor products, including those targeted for 5G applications, offset by increased sales of legacy products, including products targeting fiber to the home and licensing revenue.

In the three months ended July 2, 2021, our I&D market revenue increased by $23.3 million, or 48.6%, compared to the three months ended July 3, 2020. In the nine months ended July 2, 2021, our I&D market revenue increased by $58.5 million,

or 39.9%, compared to the nine months ended July 3, 2020. The increase in the three and nine months ended July 2, 2021 was primarily related to new program wins and expansion of our RF and microwave product lines.

In the three months ended July 2, 2021, our Data Center market revenue increased by $0.8 million, or 2.5%, compared to the three months ended July 3, 2020. In the nine months ended July 2, 2021, our Data Center market revenue increased by $22.7 million, or 27.6%, compared to the nine months ended July 3, 2020. The increase in the three months ended July 2, 2021 was driven by increased sales across various product lines. The increase in the nine months ended July 2, 2021 was primarily due to increased sales of our high-performance analog Data Center products.

Gross profit. Gross margin was 57.2% and 51.6% for the three months ended July 2, 2021 and July 3, 2020, respectively, and 55.7% and 50.3% for the nine months ended July 2, 2021 and July 3, 2020, respectively. Gross profit was $87.3 million and $70.9 million for the three months ended July 2, 2021 and July 3, 2020, respectively, and $251.6 million and $192.5 million for the nine months ended July 2, 2021 and July 3, 2020, respectively. Gross profit increased for the three and nine months ended July 2, 2021 as compared to the three and nine months ended July 3, 2020 primarily as a result of higher sales, favorable revenue mix, production efficiencies, as well as decreases in depreciation and amortization.

Research and development. Research and development expense decreased by $1.3 million, or 3.8%, to $33.6 million, or 22.0% of our revenue, for the three months ended July 2, 2021, compared to $34.9 million, or 25.5% of our revenue, for the three months ended July 3, 2020. Research and development expense decreased by $0.8 million, or 0.7%, to $105.2 million, or 23.3% of our revenue, for the nine months ended July 2, 2021, compared to $105.9 million, or 27.7% of our revenue, for the nine months ended July 3, 2020. Research and development expense decreased in the three months ended July 2, 2021 primarily as a result of lower supplies and foundry costs, lower employee-related costs, and decreased spending on computer software, partially offset by higher facility and outside service costs. Research and development expense decreased in the nine months ended July 2, 2021 primarily as a result of decreased spending on software, and lower depreciation and employee-related costs, partially offset by higher supplies, foundry costs and outside service costs.

Selling, general and administrative. Selling, general and administrative expense increased by less than $0.1 million, or 0%, to $30.0 million, or 19.6% of our revenue, for the three months ended July 2, 2021, compared to $30.0 million, or 21.8% of our revenue, for the three months ended July 3, 2020. Selling, general and administrative expense decreased by $2.6 million, or 2.7%, to $91.8 million, or 20.3% of our revenue, for the nine months ended July 2, 2021, compared to $94.3 million, or 24.6% of our revenue, for the nine months ended July 3, 2020. Selling, general and administrative expense increased in the three months ended July 2, 2021 primarily due to higher professional service fees and discretionary spending, offset by lower share-based compensation expense and amortization. Selling, general and administrative expense decreased in the nine months ended July 2, 2021 primarily due to lower depreciation, amortization and other outside service costs, offset by an increase in variable selling costs.

Restructuring (benefit) charges. There were no restructuring charges incurred during the three and nine months ended July 2, 2021 as compared to a benefit of $0.6 million and charges of $1.5 million for the three and nine months ended July 3, 2020, respectively. All restructuring actions were completed as of October 2, 2020. For additional information refer to Note 13 - Restructurings to our Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q.

Warrant liability expense. There was no warrant liability expense for the three months ended July 2, 2021, compared to an expense of $19.5 million for the three months ended July 3, 2020. Warrant liability expense was $11.1 million for the nine months ended July 2, 2021, compared to an expense of $15.0 million for the nine months ended July 3, 2020. The difference between periods 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. As of July 2, 2021, there are no remaining common stock warrants outstanding. 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 July 2, 2021, interest expense, net was $5.5 million, or 3.6% of our revenue, compared to $5.8 million, or 4.3% of our revenue, for the three months ended July 3, 2020. In the nine months ended July 2, 2021, interest expense, net was $15.1 million, or 3.3% of our revenue, compared to $22.1 million, or 5.8% of our revenue, for the nine months ended July 3, 2020. The decrease for the nine months ended July 2, 2021 is primarily due to a lower effective interest rate on our Term Loans and the decrease in our long-term debt balance.

Other expense, net. In the three months ended July 2, 2021, other expense, net was $2.7 million, or 1.7% of our revenue, compared to $4.4 million, or 3.2% of our revenue, for the three months ended July 3, 2020. In the nine months ended July 2, 2021, other expense, net was $4.3 million, or 0.9% of our revenue, compared to $12.5 million, or 3.3% of our revenue, for the nine months ended July 3, 2020. The decrease in the three and nine months ended July 2, 2021 is primarily due to lower net losses on our equity method investment, partially offset by the loss on extinguishment of debt.

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


	Three Months Ended				Nine Months Ended
	July 2, 2021		July 3, 2020		July 2, 2021		July 3, 2020
Income tax expense	482		1,750		3,349		4,716
Effective income tax rate	3.1	%	(7.5)	%	13.8	%	(8.0)	%

Our estimated annual effective tax rate for the year ended October 1, 2021 is expected to be 10%, 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 and nine months ended July 2, 2021 and the three and nine months ended July 3, 2020 was primarily driven by the continuation of a full valuation allowance against any benefit associated with U.S. losses 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. For additional information refer to Note 15 - Income Taxes to our Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q.

Cash Flow from Operating Activities

Our cash flow from operating activities for the nine months ended July 2, 2021 of $107.6 million consisted of a net income of $20.8 million, plus adjustments to reconcile our net income to cash provided by operating activities of $104.4 million, offset by cash used in operating assets and liabilities of $17.6 million. Adjustments to reconcile our net loss to cash provided by operating activities primarily included depreciation and intangible amortization expense of $52.9 million, share-based compensation expense of $26.8 million, warrant liability expense of $11.1 million, deferred financing cost amortization and write offs of $6.0 million and accretion of the discount on convertible debt of $3.9 million. In addition, cash used in operating assets and liabilities was $17.6 million for the nine months ended July 2, 2021, primarily driven by an increase in accounts receivable of $25.7 million, a decrease in inventories of $8.1 million and an increase in accounts payable of $3.1 million.

Our cash flow from operating activities for the nine months ended July 3, 2020 of $97.0 million consisted of a net loss of $63.6 million, plus cash provided by operating assets and liabilities of $37.5 million, plus adjustments to reconcile our net loss to cash provided by operating activities of $123.1 million. Adjustments to reconcile our net loss to cash provided by operating activities primarily included depreciation and intangible amortization expense of $59.8 million, share-based compensation expense of $26.9 million, warrant liability expense of $15.0 million and a loss on our equity method investment of $13.6 million. In addition, cash provided by operating assets and liabilities was $37.5 million for the nine months ended July 3, 2020, primarily driven by a decrease in prepaid expenses and other assets of $15.5 million, a decrease in inventories of $12.3 million and a decrease in accounts receivable of $9.3 million primarily due to increased revenue in the three months ended July 3, 2020 as compared to the three months ended June 28, 2019.

Cash Flow from Investing Activities

Our cash flow provided by investing activities for the nine months ended July 2, 2021 consisted primarily of proceeds of $191.3 million for the sale and maturity of short-term investments, offset by purchases of $152.3 million of short-term investments and capital expenditures of $12.9 million. Proceeds from the sale of short-term investments of $80.0 million were used to pay down the Term Loans, as discussed below under Cash Flow from Financing Activities.

Our cash flow used in used in investing activities for the nine months ended July 3, 2020 consisted primarily of purchases of $196.5 million of short-term investments and capital expenditures of $12.7 million, partially offset by proceeds of $165.8 million related to the sale and maturity of short-term investments and proceeds of $11.0 million associated with our divestment in May 2018 of certain capital equipment, inventory and other assets associated with our long-range optical subassembly product line in Japan.

Cash Flow from Financing Activities

During the nine months ended July 2, 2021, our cash used in financing activities of $119.7 million was primarily related to $545.3 million of payments on the Term Loans and $23.4 million of repurchases of stock associated with employee tax withholdings on vested equity awards, partially offset by proceeds from the 2026 Convertible Notes, net of issuance costs, of $444.2 million and $5.8 million of proceeds from stock option exercises and employee stock purchases. The early prepayment on the Term Loans of $543.6 million was made using $443.6 million of net proceeds from our 2026 Convertible Notes, cash of $20.0 million and proceeds of $80.0 million from the sale of short-term investments. See Note 8 - Debt to our Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q for additional information.

During the nine months ended July 3, 2020, our cash used in financing activities of $8.5 million was primarily related to $6.6 million of repurchases of stock associated with employee tax withholdings on vested equity awards, $5.2 million of payments on long-term debt and $1.3 million of payments on financing leases, offset by $4.6 million of proceeds from stock option exercises and employee stock purchases.

Liquidity

As of July 2, 2021, we held $144.1 million of cash and cash equivalents, primarily deposited with financial institutions, as well as $164.8 million of liquid short-term investments. The undistributed earnings of certain foreign subsidiaries are considered indefinitely reinvested for the periods presented and we do not intend to repatriate such earnings. We believe the decision to reinvest these earnings will not have a significant impact on our liquidity. As of July 2, 2021, cash held by our indefinitely reinvested foreign subsidiaries was $36.2 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 July 2, 2021, we had $160.0 million in borrowing capacity under our Revolving Facility.

We plan to use our remaining available cash and cash equivalents, 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, 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 do so on favorable terms or at all.

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements as of July 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 July 2, 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 July 2, 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.
