FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q (the “Quarterly Report”) contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. We intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). All statements other than statements of historical facts contained in this Quarterly Report, including statements regarding our future results of operations and financial position, business strategy, the impact of the ongoing and global COVID-19 pandemic on our business, prospective products and the plans and objectives of management for future operations, may be forward-looking statements. These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

Statements regarding our future results of operations and financial position, business strategy and plans and objectives of management for future operations, including, among others, statements regarding liquidity, growth and profitability strategies and factors and trends affecting our business are forward-looking statements. Without limiting the foregoing, in some cases, you can identify forward-looking statements by terms such as “aim,” “may,” “will,” “should,” “expect,” “exploring,” “plan,” “anticipate,” “could,” “intend,” “target,” “project,” “contemplate,” “believe,” “estimate,” “predict,” “potential,” “seek,” or “continue” or the negative of these terms or other similar expressions, although not all forward-looking statements contain these words. No forward-looking statement is a guarantee of future results, performance, or achievements, and one should avoid placing undue reliance on such statements.

Forward-looking statements are based on our management’s beliefs and assumptions and on information currently available to us. Such beliefs and assumptions may or may not prove to be correct. Additionally, such forward-looking statements are subject to a number of known and unknown risks, uncertainties and assumptions, and actual results may differ materially from those expressed or implied in the forward-looking statements due to various factors, including, but not limited to, those identified in Part I., Item 2. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Part II, Item 1A “Risk Factors” in this Quarterly Report. These risks and uncertainties include, but are not limited to:

•downturns or volatility in general economic conditions, including as a result of the COVID-19 pandemic, particularly in the automotive market;

•our ability to compete effectively, expand our market share and increase our net sales and profitability;

•our ability to compensate for decreases in average selling prices of our products;

•the cyclical nature of the analog semiconductor industry;

•shifts in our product mix or customer mix, which could negatively impact our gross margin;

•our ability to manage any sustained yield problems or other delays at our third-party wafer fabrication facilities or in the final assembly and test of our products;

•any disruptions at our primary third-party wafer fabrication facilities;

•our ability to fully realize the benefits of past and potential future initiatives designed to improve our competitiveness, growth and profitability;

•our ability to accurately predict our quarterly net sales and operating results;

•our ability to adjust our supply chain volume to account for changing market conditions and customer demand;

•our reliance on a limited number of third-party wafer fabrication facilities and suppliers of other materials;

•our dependence on manufacturing operations in the Philippines;

•our reliance on distributors to generate sales;

•our indebtedness may limit our flexibility to operate our business;

•the loss of one or more significant end customers;

•our ability to develop new product features or new products in a timely and cost-effective manner;

•our ability to meet customers’ quality requirements;

•uncertainties related to the design win process and our ability to recover design and development expenses and to generate timely or sufficient net sales or margins; changes in government trade policies, including the imposition of tariffs and export restrictions;

•our exposures to warranty claims, product liability claims and product recalls;

•our ability to protect our proprietary technology and inventions through patents or trade secrets;

•our ability to commercialize our products without infringing third-party intellectual property rights;

•disruptions or breaches of our information technology systems;

•risks related to governmental regulation and other legal obligations, including privacy, data protection, information security, consumer protection, environmental and occupational health and safety, anti-corruption and anti-bribery, and trade controls;

•our dependence on international customers and operations;

•the availability of rebates, tax credits and other financial incentives on end-user demands for certain products;

•the volatility of currency exchange rates;

•risks related to acquisitions of and investments in new businesses, products or technologies, joint ventures and other strategic transactions;

•our ability to raise capital to support our growth strategy;

•our ability to effectively manage our growth and to retain key and highly skilled personnel;

•changes in tax rates or the adoption of new tax legislation;

•risks related to litigation, including securities class action litigation; and

•our ability to accurately estimate market opportunity and growth forecasts.

Moreover, we operate in an evolving environment. New risk factors and uncertainties may emerge from time to time, and it is not possible for management to predict all risk factors and uncertainties.

You should read this Quarterly Report and the documents that we reference in this Quarterly Report completely and with the understanding that our actual future results may be materially different from what we expect. We qualify all of our forward-looking statements by these cautionary statements. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained in this Quarterly Report, whether as a result of any new information, future events or otherwise.

Unless the context otherwise requires, references to “we,” “us,” “our,” the “Company” and “Allegro” refer to the operations of Allegro MicroSystems, Inc. and its consolidated subsidiaries.

1. Nature of the Business and Basis of Presentation

Allegro MicroSystems, Inc., together with its consolidated subsidiaries (“AMI” or the “Company”), is a global leader in designing, developing and manufacturing sensing and power solutions for motion control and energy-efficient systems in automotive and industrial markets. The Company was incorporated under the laws of Delaware on March 30, 2013 under the name of Sanken North America, Inc. (“SKNA”) as a wholly owned subsidiary of Sanken Electric Co., Ltd. (“Sanken”). In October 2017, Sanken sold 28.8% of the common stock of SKNA to One Equity Partners (“OEP”). In April 2018, SKNA filed a certificate of amendment in the state of Delaware to change its name to Allegro MicroSystems, Inc. The Company is headquartered in Manchester, New Hampshire and has a global footprint with 16 locations across four continents.

The accompanying unaudited condensed consolidated financial statements have been prepared by the Company. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The unaudited condensed consolidated financial statements include the Company's accounts and those of its subsidiaries. All intercompany balances have been eliminated in consolidation. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Registration Statement on Form S-1 filed with the SEC on February 2, 2021 (the “Registration Statement”). In the opinion of the Company's management, the financial information for the interim periods presented reflects all adjustments necessary for a fair presentation of the Company's financial position, results of operations and cash. The results reported in these unaudited condensed consolidated financial statements are not necessarily indicative of results that may be expected for the entire year.

On November 2, 2020, the Company completed its initial public offering (“IPO”) of 28,750,000 shares of its common stock at an offering price of $14.00 per share, of which 25,000,000 shares were sold by the Company and 3,750,000 shares were sold by selling stockholders, resulting in net proceeds to the Company of approximately, $321,425 after deducting $20,125 of underwriting discounts and $8,450 of offering costs. The Company’s common stock is now listed on the Nasdaq Global Select Market under the ticker symbol “ALGM.”

On March 28, 2020, the Company entered into an agreement to divest a majority of its ownership interest in Polar Semiconductor, Inc. (“PSL”) to Sanken, in order to better align with its fabless, asset-lite scalable manufacturing strategy (the “PSL Divestiture”). In order to affect this in-kind, noncash transaction, Sanken contributed the forgiveness of the fair value of the entire related party notes payable of $42,700 owed by PSL to Sanken and the Company contributed the forgiveness of the fair value of $15,000 out of the $66,377 total debt owed by PSL to the Company, which was previously eliminated in consolidation. The entire net receivable balance of $51,377 plus accrued interest of $762 was repaid on October 14, 2020. Following the divestiture, Sanken held a 70% majority share in PSL with the Company retaining a 30% minority shareholder interest. The investment was recorded for the 30%, totaling $25,250 at the divestiture date. Beginning with reporting periods on and after March 28, 2020, the investment is included on the Company’s balance sheet as an equity investment in a related party, including $949 and $1,407 of income earned during the three- and nine-month periods ended December 25, 2020.

In addition, the difference between the fair value contributed by both parties at the consummation of this transaction and the book value was treated as an adjustment of capitalization changes related to organizational structure of affiliates and direct and indirect interests in subsidiaries within additional paid-in capital of $19,165 at December 25, 2020. This amount includes an estimated tax effect of $1,552 for the nine-month period ended December 25, 2020.

On March 28, 2020, in connection with the divestiture described above, the Company also formally terminated its distribution agreement with Sanken to distribute Sanken’s products and entered into a transitional services agreement with PSL, which contracted with Sanken as its new channel for fulfillment of Sanken product sales in North America and Europe. Sanken will continue to provide distribution support for the Company’s products in Japan. See Note 20, “Related party transactions,” for further discussion.

Impact of the COVID-19 Pandemic

On March 11, 2020, the COVID-19 outbreak was declared a pandemic by the World Health Organization. The pandemic has resulted in governments around the world implementing increasingly stringent measures to help control the spread of the virus, including quarantines, “shelter in place” and “stay at home” orders, travel restrictions, business curtailments, school closures and other measures. In addition, governments and central banks in several parts of the world have enacted fiscal and monetary stimulus measures to counteract the impacts of the COVID-19 pandemic.

The Company continues to monitor the rapidly evolving conditions and circumstances as well as guidance from international and domestic authorities, including public health authorities, and the Company may need to take additional actions based on their recommendations. There is considerable uncertainty regarding the impact on the Company’s business stemming from current measures and potential future measures that could restrict access to the Company’s facilities, limit manufacturing and support operations and place restrictions on the Company’s workforce and suppliers. The measures implemented by various authorities related to the COVID-19 pandemic have caused the Company to change its business practices, including those related to where employees work, the distance between employees in the Company’s facilities, limitations on the in-person meetings between employees and with customers, suppliers, service providers, and stakeholders, as well as restrictions on business travel to domestic and international locations or to attend trade shows, investor conferences and other events.

The full extent to which the ongoing COVID-19 pandemic adversely affects the Company’s financial performance will depend on future developments, many of which are outside of the Company’s control, are highly uncertain and cannot be predicted, including, but not limited to, the duration and spread of the pandemic, its severity, the effectiveness of actions to contain the virus or treat its impact and how quickly and to what extent normal economic and operating conditions can resume. The COVID-19 pandemic could also result in additional governmental restrictions and regulations, which could adversely affect the Company’s business and financial results. In addition, a recession, depression or other sustained adverse market impact resulting from COVID-19 could materially and adversely affect the Company’s business and its access to needed capital and liquidity. Even after the COVID-19 pandemic has lessened or subsided, the Company may continue to experience adverse impacts on its business and financial performance as a result of its global economic impact.

To the extent that the COVID-19 pandemic adversely affects the Company’s business, results of operations, financial condition or liquidity, it also may heighten many of the other risks. For example, if the business impacts of COVID-19 are

ALLEGRO MICROSYSTEMS, INC.

Notes to Unaudited Condensed Consolidated Financial Statements – (continued)

(Amounts in thousands, except share and per share amounts)

prolonged, this could cause the Company to recognize impairments for goodwill and certain long-lived assets including amortizable intangible assets.

The Company has taken actions to mitigate its financial risk given the uncertainty in global markets caused by the COVID-19 pandemic. During the fourth quarter of fiscal year 2020, the Company borrowed $43,000 under its revolving credit facilities. The borrowing was made as part of the Company’s ongoing efforts to preserve financial flexibility in light of the current uncertainty in the global markets and related effects on the Company’s business resulting from the COVID-19 pandemic. In connection with entering into a new revolving credit facility on September 30, 2020, the Company used cash on hand to repay all amounts outstanding under the line of credit and terminated all commitments thereunder.

On March 27, 2020, the President of the United States signed into law the Coronavirus Aid, Relief and Economic Security Act (“the CARES Act”). The CARES Act contains numerous tax provisions including a correction to the applicable depreciation rates available in the original Tax Cuts and Jobs Act (“TCJA”) for Qualified Improvement Property (“QIP”), temporarily establishes a five year carryback period for current net operating losses (“NOL”), and contains a provision for deferred payment of 2020 employer payroll taxes. The Company currently estimates cash tax benefits of the NOL and QIP changes to be $8,963 and $1,680, respectively. Additionally, the Company plans to defer payment of $2,766 of payroll taxes, with $1,383 to be paid back in the third quarter of fiscal year 2022 and the remainder in the third quarter of fiscal year 2023. Additional income tax provisions of the Act are currently being evaluated and not expected to have material impacts.

Financial Periods

The Company’s third quarter three-month period is a 13-week period ending on the last Friday in December. The Company’s 2021 fiscal three- and nine-month periods ended December 25, 2020, and the Company’s 2020 three- and nine-month periods ended December 27, 2019.

2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and disclosures of contingencies at the date of the unaudited consolidated financial statements and the reported amounts of net sales and expenses during the reporting period. Such estimates relate to useful lives of fixed and intangible assets, allowances for doubtful accounts and customer returns and sales allowances. Such estimates could also relate to the fair value of acquired assets and liabilities, including goodwill and intangible assets, net realizable value of inventory, accrued liabilities, the valuation of stock-based awards, deferred tax valuation allowances, and other reserves. On an ongoing basis, management evaluates its estimates. Actual results could differ from those estimates, and such differences may be material to the unaudited condensed consolidated financial statements.

Deferred Offering Costs

The Company capitalizes certain legal, professional accounting and other third-party fees that are directly associated with in-process equity financings as deferred offering costs until such financings are consummated. After consummation of the equity financing, these costs are recorded in stockholder’s equity as a reduction of the additional paid-in capital generated as a result of the offering. As of December 25, 2020 and March 27, 2020, the Company had $0 and $0 of deferred offering costs, respectively.

Concentrations of Credit Risk and Significant Customers

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents and accounts receivable. The Company maintains its cash and cash equivalents with financial institutions, which management believes to be of a high credit quality. To manage credit risk related to accounts receivables, the Company evaluates the creditworthiness of its customers and maintains allowances, to the extent necessary, for potential credit losses based upon the aging of its accounts receivable balances and known collection issues. The Company has not experienced any significant credit losses to date.

Notes to Unaudited Condensed Consolidated Financial Statements – (continued)

(Amounts in thousands, except share and per share amounts)

As of December 25, 2020 and March 27, 2020, Sanken accounted for 19.8% and 33.8% of the Company’s outstanding trade accounts receivable, net, respectively, including related party trade accounts receivable. No other customers accounted for 10% or more of outstanding trade accounts receivable, net during those periods.

For the three- and nine-month periods ended December 25, 2020, Sanken accounted for 16.1% and 17.4% of total net sales, respectively. No other customers accounted for 10% or more of total net sales for either of the three- and nine-month periods ended December 25, 2020. For the three- and nine-month periods ended December 27, 2019, Sanken accounted for 10.3% and 10.4% of total net sales, respectively. No other customers accounted for 10% or more of total net sales for either of the three- and nine-month periods ended December 27, 2019.

During the three-month period ended December 25, 2020 sales from customers located outside of the United States accounted for, in the aggregate, 85.4% of the Company’s total net sales, with Greater China accounting for 28.1%, Japan accounting for 16.0% and South Korea accounting for 10.7%. No other countries accounted for greater than 10% of total net sales for the three-month period ended December 25, 2020. During the nine-month period ended December 25, 2020, sales from customers located outside of the United States, in the aggregate, accounted for 86.1% of the Company’s total net sales, with Greater China accounting for 27.9%, Japan accounting for 17.4% and South Korea accounting for 10.5%. No other countries accounted for greater than 10% of total net sales for the nine-month period ended December 25, 2020.

During the three-month period ended December 27, 2019, sales from customers located outside of the United States, in the aggregate, accounted for 82.8% of the Company’s total net sales, with Japan accounting for 28.8% and Greater China accounting for 22.1%. No other countries accounted for greater than 10% of total net sales for the three-month period ended December 27, 2019. During the nine-month period ended December 27, 2019, sales from customers located outside of the United States, in the aggregate, accounted for 81.8% of the Company’s total net sales, with Japan accounting for 27.8% and Greater China accounting for 20.0%. No other countries accounted for greater than 10% of total net sales for the nine-month period ended December 27, 2019.

Impact of Recently Issued Accounting Standards

The Company qualifies as “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 and has elected to “opt in” to the extended transition related to complying with new or revised accounting standards, which means that when a standard is issued or revised and it has different application dates for public and nonpublic companies, the Company will adopt the new or revised standard at the time nonpublic companies adopt the new or revised standard and will do so until such time that the Company either (i) irrevocably elects to “opt out” of such extended transition period or (ii) no longer qualifies as an emerging growth company. The Company may choose to early adopt any new or revised accounting standards whenever such early adoption is permitted for nonpublic companies.

In February 2016, the Financial Accounting Standards Board (“FASB”) issued its new lease accounting guidance in ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02” or “the new lease standard”), subsequently amended by ASU 2018-11, Leases (Topic 842): Targeted Improvements. Under the new guidance, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Lessees will no longer be provided with a source of off-balance sheet financing. The new lease guidance also simplifies the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. The standard is effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years (i.e., January 1, 2019, for a calendar-year entity). Early application is permitted. Entities have the option of using either a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, or else a transition option (which the Company expects to use) allowing lessees to not apply the new lease standard in comparative periods but instead recognize a cumulative-effect adjustment to retained earnings as of the date of adoption. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach.

In May 2020, FASB issued ASU No. 2020-05 delaying the effective date of the new lease standard for nonpublic companies to fiscal years beginning after December 15, 2021 and interim periods within those fiscal years beginning after December 15, 2022. The Company expects to adopt this guidance during fiscal year 2022 and its assessment of the impact of adopting this standard is underway, including cataloging all leases, performing a preliminary analysis of the amounts of lease liabilities and right-of-use assets to be recorded and reviewing potential changes to the disclosures on leases. Based on this

ALLEGRO MICROSYSTEMS, INC.

Notes to Unaudited Condensed Consolidated Financial Statements – (continued)

(Amounts in thousands, except share and per share amounts)

preliminary assessment, the Company does not expect the adoption of this standard to have a significant impact on its consolidated statement of operations. However, the Company expects that the recognition of right-of-use assets and corresponding lease liabilities will have a significant impact on its consolidated balance sheet.

In June 2016, the FASB issued ASU No. 2016-13, “Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”), which adds an impairment model (known as the current expected credit loss (“CECL”) model) that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses, which the FASB believes will result in more timely recognition of such losses. The ASU is also intended to reduce the complexity by decreasing the number of credit impairment models that entities use to account for debt instruments. ASU 2016-03, along with its subsequent clarifications, was effective for public companies beginning after December 15, 2019 and is effective for nonpublic companies for fiscal years beginning after December 15, 2021. The Company is evaluating the new guidance and the expected effect on its consolidated financial statements and related disclosures. In November 2019, the FASB issued ASU No. 2019-10 delaying the effective date for all entities. For public entities, this guidance was effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. For nonpublic entities, this guidance is effective for annual periods beginning after December 15, 2022, including interim periods within those fiscal years.

In August 2018, the FASB issued ASU No. 2018-14, “Compensation—Retirement Benefits—Defined Benefit Plans—General (Topic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans” (“ASU 2018-14”), which modifies the disclosure requirements for defined benefit pension plans and other postretirement plans. ASU 2018-14 should be applied on a retrospective transition basis, and it is effective for public companies beginning after December 15, 2020 and for nonpublic companies beginning after December 15, 2021. The Company is evaluating the new guidance and the expected effect on its consolidated financial statements and related disclosures.

In August 2018, the FASB issued ASU No. 2018-13, “Fair Value Measurement” (“ASU 2018-13”), which modifies the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement, regarding transfers between levels of financial instruments, amounts of unrealized gains and losses included in other comprehensive (loss) income for Level 3 fair value measurements and the information used to determine the fair value of Level 3 fair value measurements. The standard is effective for both public and nonpublic companies, for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the potential impact that the adoption of ASU 2018-13 will have on its consolidated financial statements.

In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”). ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions for intraperiod tax allocations and deferred tax liabilities for equity method investments and adds guidance on whether a step-up in tax basis of goodwill relates to a business combination or a separate transaction. This ASU is effective for fiscal years beginning after December 15, 2020 for public companies and for fiscal years beginning after December 15, 2021 for nonpublic companies, with early adoption permitted. The Company is evaluating the new guidance and the expected effect on its consolidated financial statements and related disclosures.

In January 2020, the FASB issued ASU No. 2020-01, “Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)” (“ASU 2020-01”), which addresses accounting for the transition into and out of the equity method and provides clarification of the interaction of rules for equity securities, the equity method of accounting, and forward contracts and purchase options on certain types of securities. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020 for public companies and beginning after December 15, 2021 for nonpublic entities with early adoption permitted. The Company is currently assessing the potential impact that the adoption of ASU 2020-01 will have on its consolidated financial statements.

In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU 2020-04”) to provide temporary optional expedients and exceptions to the contract modifications, hedge relationships, and other transactions affected by reference rate reform if certain criteria are met. This ASU, which was effective for all entities upon issuance on March 12, 2020 and may be applied through December 31, 2022, is applicable to all contracts and hedging relationships that reference the London Interbank Offered Rate (“LIBOR”) or any other reference rate expected to be discontinued. The Company is still assessing the impact that the adoption of ASU 2020-04 will have on its consolidated financial statements.

3. Acquisition

On August 28, 2020, the Company closed on its purchase of Voxtel, Inc. (the “Acquisition”), a privately-held technology company located in Beaverton, Oregon that develops, manufactures and supplies photonic and advanced 3D imaging technologies. The total preliminary purchase price was $35,081, including certain earn-outs that have the potential payout of $15,000. The fair value of these earn-outs at acquisition date was $7,800.

The Acquisition has been accounted for as a business combination and, in accordance with ASC 805, Business Combinations, the Company has recorded the assets acquired and liabilities assumed at their respective fair values as of the date of the Acquisition. The following table summarizes the preliminary purchase price allocation recorded:


Estimated fair value of consideration:
Base purchase price	$	27,281
Contingent Consideration	7,800
Total estimated fair value of consideration	$	35,081
Estimated fair value of assets acquired and liabilities assumed:
Net working capital	$	4,064
Property and equipment	57
Finite-life intangible assets	13,600
Indefinite-life intangible assets	2,400
Deferred tax liability	(3,843)
Goodwill	18,803
Allocated purchase price	$	35,081

The significant intangible assets identified in the preliminary purchase price allocation discussed above include completed technology, in-process research and development, customer relationships and trademarks. Completed technology, customer relationships and trademarks are amortized over their respective useful lives on a straight-line basis. An estimated fair value of $2,400 was assigned to acquired in-process research and development costs with an indefinite life.

Amortization of completed technology is included within cost of revenue, and amortization of customer relationships and trademarks is included within selling, general and administrative expense. To value the completed technology and the in-process research and development assets, the Company utilized the income approach, specifically a discounted cash-flow method known as the multi-period excess earnings method. Customer relationships represent the underlying relationships with certain customers to provide ongoing services for products sold. The Company utilized the income approach, specifically the distribution method, a subset of the excess-earnings method to value the customer relationships and trademarks.

The following table presents the estimated fair values and useful lives of the identifiable finite-life intangible assets acquired:


	Useful Life	Fair value
Completed technology	12 years	$	13,100
Customer relationships	6 years	300
Trademarks	5 years	200
		$	13,600

Goodwill was recognized for the excess purchase price over the fair value of the net assets acquired. The goodwill reflects the value of the synergies the Company expects to realize and the assembled workforce. Goodwill from the Acquisition is included within the Company’s one reporting unit and is included in the Company’s enterprise-level annual review for impairment. Goodwill resulting from the Acquisition is not deductible for tax purposes.

The purchase price has been allocated to the tangible and intangible assets acquired and liabilities assumed based upon the respective estimates of fair value as of the date of the Acquisition, which remains preliminary, and using assumptions that the Company’s management believes are reasonable given the information then available. The final allocation of the purchase price may differ materially from the information presented in these condensed consolidated financial statements. Any

ALLEGRO MICROSYSTEMS, INC.

Notes to Unaudited Condensed Consolidated Financial Statements – (continued)

(Amounts in thousands, except share and per share amounts)

changes to the preliminary estimates of the fair value of the assets acquired and liabilities assumed will be recorded as adjustments to those assets and liabilities and residual amounts will be allocated to goodwill.

The revenues and loss before income taxes from the Acquisition were immaterial to the Company’s consolidated results for the three- and nine-month periods ended December 25, 2020. The Company has not presented pro forma results of operations for the Acquisition because it is not material to the Company's consolidated results of operations, financial position, or cash flows.

4. Revenue from Contracts with Customers

The Company generates revenue from the sale of magnetic sensor integrated circuits (“ICs”), application-specific analog power semiconductors, wafer foundry products and from the sale of Sanken-related products. The following tables summarize net sales disaggregated by core end market and application, by product and by geography for the three- and nine-month periods ended December 25, 2020 and December 27, 2019. The categorization of net sales by core end market and application is determined using various characteristics of the product and the application into which the Company’s product will be incorporated. The categorization of net sales by geography is determined based on the location the products are being shipped to.

Net sales by core end market and application:


	Three-Month Period Ended				Nine-Month Period Ended
	December 25, 2020		December 27, 2019		December 25, 2020		December 27, 2019
Core end market:
Automotive	$	113,902	$	99,074	$	279,759	$	289,681

As summarized in Note 3, “Acquisition,” the Company completed its acquisition of Voxtel, Inc. during the nine-month period ended December 25, 2020. The Company paid an amount of $35,081 to acquire Voxtel, which represents its fair value on that date. Any excess of the Acquisition consideration over the fair value of the assets acquired and liabilities assumed was allocated to goodwill, which amounted to $18,803. As a result of the Acquisition, the Company recorded finite-life intangible assets of $13,600, the types and lives of which are detailed in the above-referenced financial note. In addition, as a result of the Acquisition, the Company recorded indefinite-life intangible assets of $2,400.

The Company capitalizes external legal costs incurred in the defense of its patents when it believes that a significant, discernible increase in value will result from the defense and a successful outcome of the legal action is probable. When the Company capitalizes patent defense costs, it amortizes these costs over the remaining estimated useful life of the patent, which is generally 10 years. There were no such costs capitalized during either of the first nine months of fiscal years 2021 or 2020.

As of December 25, 2020, annual amortization expense of intangible assets for the next five fiscal years is expected to be as follows:

12. Management Long-Term Cash Incentive Plan

On August 28, 2015, the Company’s Board of Directors approved a Long-Term Cash Incentive Plan (“LTCIP”) for certain employees. Under the LTCIP, employees receive cash payments upon achievement of certain performance metrics determined based on a three-year rolling performance period. The Company had executed individual agreements with employees to pay certain incentives upon achievement of the plan conditions at the end of each three-year performance period.

In connection with its IPO, the Company offered certain employees (excluding its named executive officers) who were eligible to receive cash bonuses under the Company’s LTCIP and/or Talent Retention Incentive Program (as amended, the “TRIP”) the opportunity to elect to receive restricted stock units (“RSUs”) under its 2020 Omnibus Incentive Compensation Plan in lieu of cash payouts under the LTCIP and/or TRIP, through the LTCIP/TRIP Award RSU Conversion Program (the “RSU Conversion Program”). The expense related to the LTCIP and TRIP awards elected to be exchanged in the RSU Conversion Program amounted to $607 and $421, respectively. The number of RSUs granted to employees that elected to participate in the RSU Conversion Program is determined as a percentage of the employee’s target bonus under the LTCIP or

The investments in the Company’s major benefit plans largely consist of low-cost, broad-market index funds to mitigate risks of concentration within the market sectors. In recent years, the Company’s investment policy has shifted toward a closer matching of the interest-rate sensitivity of the plan assets and liabilities. The appropriate mix of equity and bond investments is determined primarily through the use of detailed asset-liability modeling studies that look to balance the impact of changes in the discount rate against the need to provide asset growth to cover future service cost. The Company, through its wholly owned subsidiary, Allegro MicroSystems, LLC’s (“AML”), non-U.S. defined benefit plan, has added a greater proportion of fixed income securities with return characteristics that are more closely aligned with changes in liabilities caused by discount rate volatility. There are no significant restrictions on the amount or nature of the investments that may be acquired or held by the plans.

Notes to Unaudited Condensed Consolidated Financial Statements – (continued)

(Amounts in thousands, except share and per share amounts)

During the three- and nine-month periods ended December 25, 2020, the Company contributed approximately $249 and $736 to its non-U.S. pension plan, respectively, and during the three- and nine-month periods ended December 27, 2019 the Company contributed approximately $235 and $698 to its non-U.S. pension plan, respectively. The Company expects to contribute approximately $943 to its non-U.S. pension plan in fiscal year 2021.

Other Defined Benefit Plan

In December 1993, the Company commenced with a rollover pension promise agreement (“Pension Promise”) to offer a then European employee an insured annuity upon their retirement at age 65. The employee was the only eligible participant of the Pension Promise. The impact associated with the expense and related other income with the Pension Promise was insignificant in fiscal years 2020 and 2019, respectively. The total values of the Pension Promise in the amounts of 827 and 866 British Pounds Sterling at December 25, 2020 and March 27, 2020, respectively (approximately $1,112 and $975 at December 25, 2020 and March 27, 2020, respectively), were classified with other in other assets, net and accrued retirement in other long-term liabilities in the Company’s unaudited consolidated balance sheets.

Defined Contribution Plan

Eligible AML U.S. employees may contribute up to 50% of their pretax compensation to a defined contribution plan, subject to certain limitations, and AML may match, at its discretion, 100% of the participants’ pretax contributions, up to a maximum of 5% of their eligible compensation. Matching contributions by AML totaled approximately $1,112 and $3,181 for the three- and nine-month periods ended December 25, 2020, respectively, and approximately $833 and $2,840 for the three- and nine-month periods ended December 27, 2019, respectively.

The Company, through its AML subsidiary, Allegro MicroSystems Europe, Ltd. (“Allegro Europe”), also has a defined contribution plan (the “AME Plan”) covering substantially all employees of Allegro Europe. Contributions to the AME Plan by the Company totaled approximately $207 and $592 for the three- and nine-month periods ended December 25, 2020, respectively, and approximately $201 and $560 for the three- and nine-month periods ended December 27, 2019, respectively.

The Company has a 401(k) plan that covers all employees meeting certain service and age requirements. Employees are eligible to participate in the plan upon hire when the service and age requirements are met. Employees may contribute up to 35% of their compensation, subject to the maximum contribution allowed by the Internal Revenue Service. All employees are 100% vested in their contributions at the time of plan entry. As of January 1, 2008, and until January 1, 2015, the Company’s former wholly owned subsidiary, PSL, adopted and used a Safe Harbor provision, whereby PSL contributed 3% of compensation each pay period for all eligible employees meeting the Safe Harbor criteria. As of January 1, 2015, PSL may match, at its discretion, 100% of the employee’s contribution, up to a maximum of 5% of their eligible compensation. PSL’s matching contributions in the three- and nine-month periods ended December 27, 2019 was $376 and $1,310, respectively.

16. Commitments and Contingencies

Operating Leases

The Company, through its subsidiaries, leases certain real estate property and equipment under operating lease agreements that expire at various dates between one and seven years. The leases generally require the Company to pay for utilities, insurance, taxes and maintenance. Some leases contain escalation clauses, renewal options and purchase options. There have been no material changes to these lease commitments since March 27, 2020.

Insurance

The Company, through its subsidiaries, utilizes self-insured employee health programs for employees in the United States. The Company records estimated liabilities for its self-insured health programs based on information provided by the third-party plan administrators, historical claims experience and expected costs of claims incurred but not reported. The Company monitors its estimated liabilities on a quarterly basis. As facts change, it may become necessary to make adjustments that could be material to the Company’s unaudited consolidated financial position and results of operations.

Legal proceedings

The Company is subject to various legal proceedings and claims, the outcomes of which are subject to significant uncertainty. The Company records an accrual for legal contingencies when it is determined that it is probable that a liability

ALLEGRO MICROSYSTEMS, INC.

Notes to Unaudited Condensed Consolidated Financial Statements – (continued)

(Amounts in thousands, except share and per share amounts)

has been incurred and the amount of the loss can be reasonably estimated. In making such determinations, the Company evaluates, among other things, the degree of probability of an unfavorable outcome and, when it is probable that a liability has been incurred, and its ability to make a reasonable estimate of the loss. If the occurrence of liability is probable, the Company will disclose the nature of the contingency, and if estimable, will provide the likely amount of such loss or range of loss. Furthermore, the Company does not believe there are any matters that could have a material adverse effect on financial position, results of operations or cash flows.

Indemnification

From time to time, the Company has agreed to indemnify and hold harmless certain customers for potential allegations of infringement of intellectual property rights and patents arising from the use of its products. To date, the Company has not incurred any costs in connection with such indemnification arrangements; therefore, there was no accrual of such amounts at December 25, 2020 or March 27, 2020.

Environmental Matters

The Company establishes accrued liabilities for environmental matters when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. If the contingency is resolved for an amount greater or less than the accrual, or the Company’s share of the contingency increases or decreases or other assumptions relevant to the development of the estimate were to change, the Company would recognize an additional expense or benefit in the unaudited consolidated statements of operations during the period such determination was made. No environmental accruals were established at December 25, 2020 or March 27, 2020.

17. Net (Loss) Income per Share

In connection with completion of the Company’s IPO on November 2, 2020 and immediately following the pricing of the IPO, all outstanding shares of Class A common stock and Class L common stock were automatically converted into an aggregate of 166,500,000 shares of common stock (the “Common Stock Conversion”). Outstanding shares of Class A and Class L common stock were converted to common stock in the Common Stock Conversion at conversion rates of approximately 15.822 and 13.010 shares of common stock to each share of Class A and Class L common stock, respectively. As part of the Common Stock Conversion, 2,066,508 and 1,766 shares of common stock were returned to the Company for tax payments made on behalf of holders of Class A common stock and Class L common stock, respectively, in withhold to cover tax transactions.

Prior to the Company’s IPO, shares of Class A common stock were entitled to a priority dividend of 8%. After Class A shareholders received an annualized return on capital of 8%, distributions of the remaining value were split between Class A and Class L shareholders based on the achievement of certain return targets. In determining income to the Class A stockholders for computing basic and diluted earnings per share for the three- and nine-month periods ended December 27, 2019, the Company did not allocate income to the shares of Class L common stock in accordance with ASC 260, because such classes of shares would not have shared in the distribution had all of the income for the periods been distributed. Accordingly, earnings per share calculations were provided only for the Class A shares with a weighted average of 10,000,000 shares for the three- and nine-month periods ended December 27, 2019.

The following table sets forth the basic and diluted net (loss) income attributable to Allegro MicroSystems, Inc. per share. The number of shares of common stock reflected in the calculation is the total shares of common stock (vested and unvested) held on the IPO date, after the Common Stock Conversion.

Diluted net (loss) income attributable to common stockholders per share	$	(0.04)	$	0.90	$	0.05	$	2.38

The computed net loss for the three-month period ended December 25, 2020 does not assume conversion of securities that would have an antidilutive effect on loss per share. As the Company was in a net loss position for the three-month period ended December 25, 2020, all common stock equivalents in this period were antidilutive. There were no such convertible securities to consider for the three- and nine-month periods ended December 27, 2019.

The following represents issuable weighted average share information for the respective periods:


	Three-Month Period Ended		Nine-Month Period Ended
	December 25, 2020	December 27, 2019	December 25, 2020	December 27, 2019
Unvested restricted stock units (“RSUs”)	377,767	—	125,922	—
Unvested performance stock units (“PSUs”)	422,768	—	140,923	—
Shares related to Common Stock Conversion	56,752,747	—	123,250,916	—
Total	57,553,282	—	123,517,761	—

As the Company was in a net loss position for the three-month period ended December 25, 2020, common stock equivalents of 57,553,282 were antidilutive.

18. Common Stock and Stock-Based Compensation

On November 2, 2020, the Company completed its IPO of 28,750,000 shares of its common stock at an offering price of $14.00 per share, of which 25,000,000 shares were sold by the Company and 3,750,000 shares were sold by selling stockholders, resulting in net proceeds to the Company of approximately $321,425, after deducting $20,125 of underwriting discounts and $8,450 of offering costs. The Company’s common stock is now listed on the Nasdaq Global Select Market under the ticker symbol “ALGM.”

Prior to the IPO, the Company had two classes of common stock, Class A common stock and Class L common stock. The Company’s Board of Directors authorized 12,500,000 shares of Class A common stock at par value of $0.01, out of which the Company issued 6,720,000 to Sanken in exchange for its previous shares of common stock. The previous single class of common stock was retired in full. The Company sold 2,880,000 shares of newly issued Class A common stock, representing a 28.8% ownership interest, to OEP for cash consideration of $291,000 (the “OEP Transaction”). The stock issuance proceeds were recorded net of $9,260 of related transaction costs. The Company’s Board of Directors authorized 1,000,000 shares of Class L common stock at a par value of $0.01.

Both Class A and Class L common stock were entitled to dividends when, and if, declared by the Board of Directors. Holders of shares of Class A common stock were entitled to a priority dividend of 8%. After holders of shares of Class A

ALLEGRO MICROSYSTEMS, INC.

Notes to Unaudited Condensed Consolidated Financial Statements – (continued)

(Amounts in thousands, except share and per share amounts)

common stock receive an annualized return on capital of 8%, distributions of the remaining value were split between holders of shares of Class A common stock and Class L common stock based on the achievement of certain return targets.

Each outstanding share of Class A common stock entitled the holder to one vote on each matter submitted to a vote of the stockholders of the Company, including the election of the Board of Directors. Holders of Class L common stock were not entitled to vote.

In the event of voluntary or involuntary liquidation, dissolution or winding-up of the Company, any amounts available for distribution by the Company were to be paid to the holders of Class A common stock and Class L common stock, as if such distribution were a dividend paid, factoring in the priorities as described above.

Upon the earliest of (i) an IPO; (ii) change of control; (iii) the date OEP and its affiliates cease to own any shares of capital stock of the Company; or (iv) at the election of the Board of Directors, any merger transaction involving the Company or its subsidiaries, each outstanding share of Class L common stock would convert into Class A common stock.

Also, in connection with the OEP Transaction, the Company granted 400,000 unvested shares of Class A common stock and 597,400 unvested shares of Class L common stock to certain Company employees. The shares of Class A common stock vest to the grantees over a service period of 60 months. However, they remain subject to the Company’s repurchase right at par value in the event that either (i) a change in control has not occurred or (ii) the Company has not consummated an IPO by the seventh anniversary of the OEP Transaction. As of March 27, 2020, the Company was not able to determine whether such a change in control or IPO was probable, and therefore, no amount of stock-based compensation was recognized for the unvested shares of Class A common stock at that time. As a result of the Company’s IPO closing on November 2, 2020, the unvested shares of Class A common stock immediately become vested and the Company recognized $40,440 of one-time stock-based compensation (400,000 shares to management at $101.10 per share) at that time.

The Class L unvested shares vested on a straight-line basis over a service period of four years. Class L unvested shares had no other vesting conditions. If an IPO occurred, 25% of the unvested awards would accelerate vesting if 25% or more of the awards are unvested at the time of the IPO. If a change in control occurs, 100% of the then unvested awards would accelerate vesting. Accordingly, based on the Company’s IPO closing on November 2, 2020, the Company accelerated the vesting of the 25% unvested awards at that time.

Prior to the IPO, the Company issued 17,203 shares of Class L common stock during the nine-month period ended December 25, 2020 with a weighted average price per share of $33.83 and issued 30,300 shares of Class L common stock during the nine-month period ended December 27, 2019 with a weighted average price per share of $26.93.

On October 2, 2020, the Company repurchased an aggregate of 1,997 shares of its Class L common stock from certain of its directors and one of its non-executive employees for an aggregate purchase price of $408 in connection with (i) in the case of such directors, the settlement of certain outstanding promissory notes issued by the Company to such directors, and (ii) in the case of such non-executive employee, to satisfy certain withholding tax obligations triggered by the vesting of such shares in accordance with the terms of the applicable award agreement.

Immediately following the pricing of the IPO on November 2, 2020, all outstanding shares of Class A common stock and Class L common stock were automatically converted into an aggregate of 166,500,000 shares of common stock (the “Common Stock Conversion”). Outstanding shares of Class A and Class L common stock were converted to common stock in the Common Stock Conversion at conversion rates of approximately 15.822 and 13.010 shares of common stock to each share of Class A and Class L common stock, respectively. As part of the Common Stock Conversion, 2,066,508 and 1,766 shares of common stock were returned to the Company for tax payments made on behalf of holders of Class A common stock and Class L common stock, respectively, in withhold to cover tax transactions. Outstanding loan amounts related to Class L common stock in the aggregate amount of $753 were extinguished on October 2, 2020.

The following table presents the respective number of shares of common stock and unvested restricted common stock issued in the Common Stock Conversion. The number of shares of common stock and unvested restricted common stock issuable are based upon the vesting provisions of the outstanding shares and reflect the shares vested and unvested at the date of conversion.

	Shares of Common Stock	Shares of Unvested Restricted Common Stock	Total Shares of Common Stock
Class A common stock	156,155,403	—	156,155,403
Class L common stock	7,816,574	459,749	8,276,323
Total	163,971,977	459,749	164,431,726

Prior to the IPO, there were 638,298 shares of Class L common stock outstanding at a weighted average price per share of $11.99. As noted in the above table, as part of the Common Stock Conversion, the Class L common stock was converted to 7,816,574 shares of common stock and 459,749 of unvested restricted common stock at weighted average prices per share of $14.00.

In connection with its IPO, the Company offered certain employees (excluding its named executive officers) who were eligible to receive cash bonuses under the Company’s LTCIP and TRIP the opportunity to elect to receive RSUs under its 2020 Omnibus Incentive Compensation Plan in lieu of cash payouts under the LTCIP and/or TRIP, through the LTCIP/TRIP Award RSU Conversion Program (the “RSU Conversion Program”). The expense related to the LTCIP and TRIP awards elected to be exchanged in the RSU Conversion Program amounted to $607 and $421, respectively. The number of RSUs granted to employees that elected to participate in the RSU Conversion Program is determined as a percentage of the employee’s target bonus under the LTCIP or TRIP, and amounted to 602,490 and 348,911 RSUs on behalf of the LTCIP and TRIP conversion, respectively, at a grant date fair value of $14.00. If an employee elected to not to participate in the RSU Conversion Program, the LTCIP or TRIP award will continue under its existing terms and conditions.

In addition to above, the Company also issued RSUs to its non-employee directors as consideration for their provision of future services. The stock-based compensation expense related to RSUs is measured based on the fair value market price of the Company’s common shares on the grant date and is recognized on a straight-line basis over the requisite service period, which coincides with the vesting period. RSUs can only be exchanged and settled for the Company’s common shares, on a one-to-one basis, upon vesting. RSUs are generally subject to forfeiture prior to the release of vesting restrictions. Included in the table below is a total amount of 54,644 RSUs issued to such non-employee directors.

The following table summarizes the RSU activity for the nine-month period ended December 25, 2020:


	Number of Shares	Weighted-Average Grant-Date Fair Value		Weighted-Average Remaining Contractual Life (In years)	Aggregate Intrinsic Value
Outstanding - March 27, 2020	—	$	—	—	$	—
Granted	1,426,944	14.04

Canceled	(28,920)	14.00
Outstanding - December 25, 2020	1,397,648	$	14.04	1.74	$	34,648

The weighted-average grant fair value per share for RSUs granted during the nine-month period ended December 25, 2020 was $14.04, and the stock-based compensation expense related to non-vested awards not yet recorded at December 25, 2020 was $17,496, which is expected to be recognized over a weighted-average of 1.74 years. During the nine-month period ended December 25, 2020, 376 shares vested.

The Company also awards PSUs to its senior executive officers based on achievement of medium-term plans (“MTP”) approved in meetings of its Board of Directors for establishing target performances. Each award reflects a target number of shares (“Target Shares”) that may be issued to the award recipient. In fiscal year 2021, these awards are earned upon the completion of a three-year performance period ending March 31, 2023. Whether units are earned at the end of the performance period will be determined based on the achievement of certain performance objectives over the performance period. The performance objectives include achieving certain revenue improvement and cumulative EBITDA levels for the performance period, and also include a performance objective relating to relative total shareholder return (“TSR”). Depending on the results achieved during the three-year performance period, the actual number of shares that a grant recipient may receive at the end of the period ranges from —% to 200% of the Target Shares granted.

The weighted-average fair value of the PSUs was determined using the Monte Carlo simulation model incorporating the following weighted-average assumptions:

PSUs are included at 100% - 200% of target goals. The intrinsic value of the PSU’s vested during the nine-month period ended December 25, 2020 was $16,121. The total compensation cost related to non-vested awards not yet recorded at December 25, 2020 was $9,320, which is expected to be recognized over a weighted average of 2.90 years. No shares were vested during the nine-month period ended December 25, 2020.

19. Income Taxes

The Company recorded the following tax (benefit) provision in its unaudited consolidated statements of operations:


	Three-Month Period Ended						Nine-Month Period Ended
	December 25, 2020			December 27, 2019			December 25, 2020			December 27, 2019
Operating taxes	$	(12,169)		$	1,703		$	(9,764)		$	5,980
Discrete tax items	(18,354)			(161)			(18,149)			5,730
(Benefit) provision for income taxes	$	(30,523)		$	1,542		$	(27,913)		$	11,710
Annual operating tax rate	34.2		%	16.2		%	52.8		%	16.9		%
Effective tax rate	85.8		%	14.7		%	150.9		%	33.0		%

The Company’s provision for income taxes is comprised of the year to date taxes based on an estimate of the annual effective tax rate plus the tax impact of discrete items.

The Company is subject to tax in the United States (“U.S.”) and various foreign jurisdictions. The Company’s effective tax rate can fluctuate primarily based on: the mix of its U.S. and foreign income; the impact of discrete transactions; and the difference between the amount of tax benefit generated by the foreign derived intangible income deduction (“FDII”) and research credits offset by the additional tax from the global intangible low-tax income (“GILTI”) and the base erosion tax (“BEAT”).

The Company regularly assesses the likelihood of outcomes that could result from the examination of its tax returns by the IRS, and other tax authorities to determine the adequacy of its income tax reserves and expense. Should actual events or results differ from the Company’s then-current expectations, charges or credits to the Company’s provision for income taxes may become necessary. Any such adjustments could have a significant effect on the results of operations.

For the three months ended December 25, 2020 and December 27, 2019, the Company’s effective income tax (benefit) expense and rates were a benefit of $30,523 or 85.8% and expense of $1,542 or 14.7% on pre-tax loss of $35,583 and income of $10,500, respectively. For the nine-month period ended December 25, 2020 and December 27, 2019, the Company’s effective income tax (benefit) expense and rates were a benefit of $27,913 or 150.9% and expense of $11,710 or 33.0% on pre-tax loss of $18,501 and income of $35,486, respectively.

The change in effective income tax rates is primarily due to the $40,440 IPO related stock-based compensation charge which significantly reduced U.S. income and was included in the Company’s tax rate from operations in the quarter. The incremental stock-based compensation windfall was treated as a discrete tax adjustment as an incremental tax deduction in the three months ended December 25, 2020. Additionally, other discrete transactions, the divestiture of Polar and the one-time dividend resulted in additional tax deductions. The reduction in U.S. income and the discrete tax deductions resulted in a U.S. tax NOL that can be carried back to refund prior years’ taxes. In total approximately $18,149 of discrete tax benefits recorded this quarter were partially offset by a reduction in our FDII deduction and an increase in GILTI and BEAT tax.

Additionally, in the first quarter of fiscal year 2020, there was a discrete tax expense of approximately $5,500 recorded for the settlement of IRS transfer pricing audits for years 2016, 2017, and 2018.

Overview

Allegro MicroSystems, Inc., together with its consolidated subsidiaries (“AMI”, “we”, “us” or “our”) is a leading global designer, developer, manufacturer and marketer of sensor integrated circuits (“ICs”) and application-specific analog power ICs enabling the most important emerging technologies in the automotive and industrial markets. We are the number one supplier of magnetic sensor IC solutions worldwide based on market share, driven by our market leadership in automotive. We focus on providing complete IC solutions to sense, regulate and drive a variety of mechanical systems. This includes sensing angular or linear position of a shaft or actuator, driving an electric motor or actuator, and regulating the power applied to sensing and driving circuits so they operate safely and efficiently.

We are headquartered in Manchester, New Hampshire and have a global footprint with 16 locations across four continents. Our portfolio includes more than 1,000 products, and we ship over one billion units annually to more than 10,000 customers worldwide. During the three- and nine-month periods ended December 25, 2020, we generated $164.4 million and $416.1 million in total net sales, respectively, with $5.1 million in net loss and $9.4 million in net income, and $39.6 million and $98.6 million in Adjusted EBITDA in such fiscal periods, respectively. During the three- and nine-month periods ended December 27, 2019, we generated $159.8 million and $475.5 million in total net sales, respectively, with $9.0 million and $23.8 million in net income and $30.8 million and $89.4 million in Adjusted EBITDA in such fiscal periods, respectively.

On November 2, 2020, we completed our initial public offering (“IPO”) of 28,750,000 shares of our common stock at an offering price of $14.00 per share, of which 25,000,000 shares were sold by us and 3,750,000 shares were sold by selling stockholders, resulting in net proceeds to us of approximately, $321.4 million after deducting $20.1 million of underwriting discounts and $8.5 million of offering costs. Our common stock is now listed on the Nasdaq Global Select Market under the ticker symbol “ALGM.”

Our Growth Strategies and Outlook

We plan to pursue the following strategies to continue to grow our sales and enhance our profitability:

•Invest in research and development that is market-aligned and focused on targeted portfolio expansion. We believe that our investments in research and development in the areas of product design, automotive-grade wafer fabrication technology and IC packaging development are critical to maintaining our competitive advantage. In both the automotive and industrial markets, major technology shifts driven by disruptive technologies are creating high-growth opportunities in areas such as xEVs, advanced driving assistance systems (“ADAS”), Industry 4.0, data centers and green energy applications. Our knowledge of customers’ end systems has driven an expansion of our sensor IC and power solutions to enable these new technologies. By aligning our research and development investments with disruptive technology trends while undergoing a rigorous ROI review, we believe we can deliver an attractive combination of growth and profitability.

• Emphasize the automotive “first” philosophy to align our product development with the most rigorous applications and safety standards. We have been intentional about incorporating support for the stringent automotive operating voltages, temperature ranges and safety and reliability standards into every part of our operations, from design to manufacturing. We believe our focus on meeting or exceeding industry standards as the baseline for product development increases our opportunity in the automotive market as customers look for trusted suppliers to deliver highly reliable solutions for rapidly growing emerging markets, and that our philosophy of designing for automotive safety and reliability gives us a meaningful lead over new entrants attempting to enter the automotive market. For example, we will apply this philosophy of innovation, quality and reliability to our new photonics portfolio which supplies components into safety-critical Light Detection and Ranging (“LiDAR”) applications. We also believe we can use our expertise in designing for the automotive market and our expanding product portfolio to capitalize on increasing demand among industrial customers for ruggedized solutions that meet the highest quality and reliability standards. Additionally, in our experience, demand for solutions that meet or exceed stringent safety and reliability specifications supports higher average selling prices (“ASPs”) and lower ASP declines over time than are typical for our industry.

•Invest to lead in chosen markets and apply our intellectual property and technology to pursue adjacent growth markets. We intend to continue to invest in technology advancements and our intellectual property portfolio to maintain the number one market share position in magnetic sensor ICs and achieve leadership positions in power ICs within our target markets. We believe that leveraging our technology and existing research and development, sales and support efforts will enable us to take advantage of synergistic opportunities in new, adjacent growth markets. We believe this strategy of leveraging our known capabilities to target adjacent growth markets will enable us to enjoy greater returns on our research and development investments.

•Expand our sales channels and enhance our sales operations and customer relationships. Our global sales infrastructure is optimized to support customers through a combination of key account managers and regional technical and support centers near customer locations that enable us to act as an extension of our customers’ design teams, providing us with key insights into product requirements and accelerating the adoption and ramp up of our products in customer designs. We intend to continue strengthening our relationships with our existing customers while also enabling our channel partners to support demand creation and fulfillment for smaller broad-based industrial customers. We believe we will be able to further penetrate the industrial market and efficiently scale our business to accelerate growth by enabling our channel partners to become an extension of our demand generation and customer support efforts.

•Continue to improve our gross margins through product innovation and cost optimization. We strive to improve our profitability by both rapidly introducing new products with value-added features and reducing our manufacturing costs through our fabless, asset-lite manufacturing model. We expect to continue to improve our product mix by developing new products for growth markets where we believe we can generate higher ASPs and/or higher gross margins. We also intend to further our relationships with key foundry suppliers to apply our product and applications knowledge to develop differentiated and cost-efficient wafer processes and packages. We believe we can reduce our manufacturing costs by leveraging the advanced manufacturing capabilities of our strategic suppliers, implementing more cost-effective packaging technologies and leveraging both internal and external assembly and test capacity to reduce our capital requirements, lower our operating costs, enhance reliability of supply and support our continued growth.

•Pursue selective acquisitions and other strategic transactions. We evaluate and pursue selective acquisitions and other transactions to facilitate our entrance into new applications, add to our intellectual property portfolio and design resources, and accelerate our growth. From time to time, we acquire companies, technologies or assets and participate in joint ventures when we believe they will cost effectively and rapidly improve our

product development or manufacturing capabilities or complement our existing product offerings. For example, our August 2020 acquisition of Voxtel, Inc. and its affiliate LadarSystems, Inc. brings together Voxtel’s laser and imaging expertise and our automotive leadership and scale to enable what we believe will be the next generation of ADAS.

•Maintain commitment to sustainability. We intend to continue to innovate with purpose, addressing critical global challenges related to energy efficiency, vehicle emissions and clean and renewable energy with our sensing and power management product portfolio. In addition, we strive to operate our business in a socially responsible and environmentally sustainable manner, and we strive to maintain a commitment to social responsibility in our supply chain and disclosure of the environmental impact of our business operations.

Recent Initiatives to Improve Results of Operations

We have recently implemented several initiatives designed to improve our operating results.

On August 28, 2020, we acquired Voxtel, Inc., a privately-held technology company located in Beaverton, Oregon that specializes in components for eye-safe LiDAR used in ADAS, fully autonomous vehicles, and industrial automation. The total preliminary purchase price of the acquisition was $35.1 million, including certain earnouts that have a potential payout of $15.0 million. The fair value of these earn-outs at acquisition date was $7.8 million. In addition to the laser technology, Voxtel’s capabilities include its Indium Gallium Arsenide (“InGaAs”) Avalanche Photodiode (“APDs”) and APD photoreceivers—highly sensitive in the important eye-safe region around 1550 nanometers (“nm”). This technology enables images to be obtained over a wide range of weather conditions and over a long-distance or a wide field of view using a laser that does not pose an ocular hazard. The combination of these highly sensitive detectors and high-peak-power eye-safe lasers with Voxtel’s custom integrated circuits and electro-optical packaging expertise, allows for cost-effective, compact laser-ranging and 3D-image sensing. In addition, Voxtel holds more than 38 US patents, representing a comprehensive Laser Detection and Ranging (“LADAR”)/LiDAR photonic technology suite.

Through the end of fiscal year 2020, we held a 100% ownership interest in Polar Semiconductor, LLC (“PSL”), a semiconductor wafer fabricator engaged in the manufacturing and testing of foundry wafers. Prior to the divestiture transaction of PSL, foundry revenue accounted for 10.4% and 10.4% of our net sales and supplied 45.8% and 47.7% of our wafer requirements in the three- and nine-month periods ended December 27, 2019, respectively. In addition, through end of fiscal year 2020, we acted as a distributor of Sanken products in North America, South America and Europe on a low-margin, buy-resale basis pursuant to the Sanken Products Distribution Agreement between AML, our wholly owned subsidiary, and Sanken. Our net sales from the distribution of Sanken products in the three- and nine-month periods ended December 27, 2019 were $7.7 million and $26.7 million, respectively. On March 28, 2020, in order to further our strategy for developing a flexible and efficient manufacturing model that minimizes capital requirements, lowers operating costs, enhances reliability of supply and supports our growth going forward:

•We divested a majority of our ownership interest in PSL to Sanken in (the “PSL Divestiture”), in connection with which:

•Our equity interests in PSL were recapitalized (the “Recapitalization”) in exchange for (i) the contribution by us to PSL of $15.0 million of intercompany debt, representing a portion of the aggregate principal amount of debt owed by PSL to us under certain intercompany loan agreements (the “Existing Allegro Loans”), (ii) the assumption by us of $42.7 million in aggregate principal amount of debt owed by PSL to Sanken under certain intercompany loan and line of credit agreements (the “PSL-Sanken Loans”), that was subsequently forgiven in exchange for our transfer to Sanken of 70% of the issued and outstanding equity interests in PSL, and (iii) the termination of the Existing Allegro Loans and the issuance, pursuant to a consolidated and restructured loan agreement (the “Consolidated Loan Agreement”), of a note payable to us in an aggregate principal amount of $51.4 million (representing the aggregate principal amount of debt outstanding under the Existing Allegro Loans prior to their termination); and

•In exchange for the extinguishment of all outstanding indebtedness owed by us to Sanken under the PSL-Sanken Loans, we (i) divested 70% of the issued and outstanding equity interests in PSL to Sanken, as a

result of which Sanken holds a 70% majority share in PSL and we hold a 30% interest, and (ii) amended and restated the existing limited liability company agreement of PSL to admit Sanken as a member, reflect the Recapitalization and otherwise reflect the rights and obligations of us and Sanken thereunder;

•AML entered into a letter agreement with Sanken providing for, among other things, the termination of AML’s services under the Sanken Products Distribution Agreement, and Sanken and PSL entered into a new distribution agreement providing for PSL to serve as a distributor of Sanken products in North America, South America and Europe; and

•We entered into certain other agreements and transactions with Sanken and PSL as more fully described under “Prospectus Summary—The Divestiture Transactions” in the Registration Statement and elsewhere in this Quarterly Report.

As a result of the PSL Divestiture and the transfer of the Sanken products distribution business to PSL, we expect continued material improvement over this fiscal year in gross profit, operating income and net income, as well as reduced capital expenditures and increased net cash provided by operating activities. Strategically, we believe these changes better enable us to focus solely on our core business in sensor and power applications for the automotive and industrial end markets.

•PSL foundry revenue is no longer consolidated in our results in fiscal year 2021, however, PSL did supply 40.9% and 37.1% of our wafer requirements in the three- and nine-month periods ended December 25, 2020, respectively.

•Net sales from the distribution of Sanken products are also no longer consolidated in our results in fiscal year 2021.

In February 2020, we announced that we would consolidate our assembly and test facilities into a single site, located at our manufacturing facility in the Philippines (the “AMPI Facility”). As such, we have commenced the closure of our manufacturing facility in Thailand (the “AMTC Facility”). We expect to substantially complete this transition by the end of March 2021. We expect to realize a material reduction in cost of goods sold in subsequent periods.

Impact of the COVID-19 Pandemic

We continue to monitor the rapidly evolving conditions and circumstances as well as guidance from international and domestic authorities, including public health authorities, and we may need to take additional actions based on their recommendations. There is considerable uncertainty regarding the impact on our business stemming from current measures and potential future measures that could restrict access to our facilities, limit manufacturing and support operations and place restrictions on our workforce and suppliers. The measures implemented by various authorities related to the COVID-19 outbreak have caused us to change our business practices including those related to where employees work, the social distance employees are required to keep in our facilities, limitations on in-person meetings with customers, suppliers, service providers and stakeholders, as well as restrictions on business travel to domestic and international locations or to attend trade shows, investor conferences and other events.

The full extent to which the ongoing COVID-19 pandemic adversely affects our financial performance will depend on future developments, many of which are outside of our control, are highly uncertain and cannot be predicted, including, but not limited to, the duration and spread of the pandemic, its severity, the effectiveness of actions to contain the virus or treat its impact and how quickly and to what extent normal economic and operating conditions can resume. The COVID-19 pandemic could also result in additional governmental restrictions and regulations, which could adversely affect our business and financial results. In addition, a recession, depression or other sustained adverse market impact resulting from COVID-19 could materially and adversely affect our business and our access to needed capital and liquidity. Even after the COVID-19 pandemic has lessened or subsided, we may continue to experience adverse impacts on our business and financial performance as a result of its global economic impact.

To the extent that the COVID-19 pandemic adversely affects our business, results of operations, financial condition or liquidity, it also may heighten many of the other risks; for example, if the business impacts of COVID-19 continue for an extended period, we may be required to recognize impairments for goodwill and certain long-lived assets including amortizable intangible assets. We have taken actions to mitigate our financial risk given the uncertainty in global markets caused by the COVID-19 pandemic. In March 2020, we borrowed $43.0 million under our credit facilities (including $10.0 million borrowed by PSL under the PSL Revolver, the proceeds of which were retained by PSL and are no longer available for use by us following the consummation of the PSL Divestiture). The borrowing was made as part of our ongoing efforts to preserve financial flexibility considering the current uncertainty in the global markets and related effects on our business resulting from the COVID-19 pandemic.

On March 27, 2020, the President of the United States signed into law the Coronavirus Aid, Relief and Economic Security Act (“the CARES Act”). The CARES Act contains numerous tax provisions, including a correction to the applicable depreciation rates available in the Tax Cuts and Jobs Act of 2017 (“TCJA”) for Qualified Improvement Property (“QIP”), temporarily establishes a five year carryback period for current net operating losses (“NOL”), and contains a provision for deferred payment of 2020 employer payroll taxes. We currently estimate cash tax benefits of the NOL and QIP changes to be $8,963 and $1,680, respectively. Additionally, we plan to defer payment of $2,766 of payroll taxes, with $1,383 to be paid back in the third quarter of fiscal year 2022 and the remainder in the third quarter of fiscal year 2023. Additional income tax provisions of the Act are currently being evaluated and not expected to have material impacts.

Other Key Factors and Trends Affecting our Operating Results

Our financial condition and results of operations have been, and will continue to be, affected by numerous other factors and trends, including the following:

Design Wins with New and Existing Customers

Our end customers continually develop new products in existing and new application areas, and we work closely with our significant OEM customers in most of our target markets to understand their product roadmaps and strategies. For new products, the time from design initiation and manufacturing until we generate revenue can be lengthy, typically between two and four years. As a result, our future revenue is highly dependent on our continued success at winning design mandates from our customers. Further, because we expect the ASPs of our products to decline over time, we consider design wins to be critical to our future success and anticipate being increasingly dependent on revenue from newer design wins for our newer products. The selection process is typically lengthy and may require us to incur significant design and development expenditures in pursuit of a design win with no assurance that our solutions will be selected. As a result, the loss of any key design win or any significant delay in the ramp-up of volume production of the customer’s products into which our product is designed could adversely affect our business. In addition, volume production is contingent upon the successful market introduction and acceptance of our customer’s end products, which may be affected by several factors beyond our control.

Customer Demand, Orders and Forecasts

Demand for our products is highly dependent on market conditions in the end markets in which our customers operate, which are generally subject to seasonality, cyclicality and competitive conditions. In addition, a substantial portion of our total net sales is derived from sales to customers that purchase large volumes of our products. These customers generally provide periodic forecasts of their requirements, but these forecasts do not commit such customers to minimum purchases, and customers can revise these forecasts without penalty. In addition, as is customary in the semiconductor industry, customers are generally permitted to cancel orders for our products within a specified period. Cancellations of orders could result in the loss of anticipated sales without allowing us sufficient time to reduce our inventory and operating expenses. In addition, changes in forecasts or the timing of orders from customers exposes us to the risks of inventory shortages or excess inventory.

Manufacturing Costs and Product Mix

Gross margin, or gross profit as a percentage of total net sales, has been, and will continue to be, affected by a variety of factors, including the ASPs of our products, product mix in a given period, material costs, yields, manufacturing costs and efficiencies. We believe the primary driver of gross margin is the ASP negotiated between us and our customers relative to material costs and yields. Our pricing and margins depend on the volumes and the features of the products we produce and sell to our customers. As our products mature and unit volumes increase, we expect their ASPs to decline. We continually monitor and work to reduce the cost of our products and improve the potential value our solutions provide to our customers

as we target new design win opportunities and manage the product life cycles of our existing customer designs. We also maintain a close relationship with our suppliers and subcontractors to improve quality, increase yields and lower manufacturing costs. As a result, these declines often coincide with improvements in manufacturing yields and lower wafer, assembly, and testing costs, which offset some or all of the margin reduction that results from declining ASPs. However, we expect our gross margin to fluctuate on a quarterly basis as a result of changes in ASPs due to product mix, new product introductions, transitions into volume manufacturing and manufacturing costs. Gross margin generally decreases if production volumes are lower as a result of decreased demand, which leads to a reduced absorption of our fixed manufacturing costs. Gross margin generally increases when the opposite occurs.

Cyclical Nature of the Semiconductor Industry

The semiconductor industry is highly cyclical and is characterized by increasingly rapid technological change, product obsolescence, competitive pricing pressures, evolving standards, short product life cycles and fluctuations in product supply and demand. New technology may result in sudden changes in system designs or platform changes that may render some of our products obsolete and require us to devote significant research and development resources to compete effectively. Periods of rapid growth and capacity expansion are occasionally followed by significant market corrections in which sales decline, inventories accumulate and facilities go underutilized. During periods of expansion, our margins generally improve as fixed costs are spread over higher manufacturing volumes and unit sales. In addition, we may build inventory to meet increasing market demand for our products during these times, which serves to absorb fixed costs further and increase our gross margins. During an expansion cycle, we may increase capital spending and hiring to add to our production capacity. During periods of slower growth or industry contractions, our sales, production and productivity suffer and margins generally decline. We are currently in a period in which our manufacturing volumes are below optimal levels, as a result of the impact of COVID-19 on our primary end-market, i.e., automotive.

Components of Our Results of Operations

Net sales

Our total net sales are derived from product sales to direct customers and distributors. We sell products globally through our direct sales force, third party and related party distributors and independent sales representatives. Sales are derived from products for different applications. Our core applications are focused on the automotive, industrial and other industries. Additionally, until the consummation of the PSL Divestiture following the end of fiscal year 2020, we also manufactured products for other applications such as wafer foundry products and acted as a distributor of Sanken products in North America, South America and Europe.

We sell magnetic sensor ICs power ICs and photonics, and prior to the consummation of the PSL Divestiture following the end of fiscal year 2020, we also sold wafer foundry products and acted as a distributor for Sanken products in North America, South America and Europe. Revenue is generally recognized when control of the products is transferred to the customer, which typically occurs upon shipment or delivery, depending on the terms of the contract. When we transact with a distributor, our contractual arrangement is with the distributor and not with the end customer. Whether we transact business with and receive the order from a distributor or directly from an end customer through our direct sales force and independent sales representatives, our revenue recognition policy and resulting pattern of revenue recognition for the order are the same. We recognize revenue net of sales returns, price protection adjustments, stock rotation rights and any other discounts or credits offered to our customers.

Stock-based compensation

In addition to the ratable vesting of our stock-based compensation, upon completion of our IPO we recognized one-time stock-based compensation charges of $40.4 million in connection with the vesting of all outstanding shares of Class A common stock, $1.6 million in connection with the automatic acceleration of 25% of the standard vesting term of shares of Class L common stock and $1.0 million through the LTCIP/TRIP Award RSU Conversion Program (the “RSU Conversion Program”). In the three- and nine-month periods ended December 25, 2020 these one-time stock based compensation charges were allocated to cost of goods sold, research and development expenses and selling, general and administrative expenses in the amounts of $4.4 million, $2.3 million and $36.3 million, respectively.

Cost of goods sold, gross profit and gross margin

Cost of goods sold consists primarily of costs of purchasing raw materials, costs associated with probe, assembly, test and shipping our products, costs of personnel, including stock-based compensation, costs of equipment associated with manufacturing, procurement, planning and management of these processes, costs of depreciation and amortization, costs of logistics and quality assurance, and costs of royalties, value-added taxes, utilities, repairs and maintenance of equipment, and an allocated portion of our occupancy costs. In addition, prior to the PSL Divestiture, costs of goods sold also consisted of finished silicon wafers processed by internal and independent foundries.

Gross profit is calculated as total net sales less cost of goods sold. Gross profit is affected by numerous factors, including average selling price, revenue mix by product, channel and customer, foreign exchange rates, seasonality, manufacturing costs and the effective utilization of our facilities. Another factor impacting gross profit is the time required for the expansion of existing facilities to reach full production capacity. As a result, gross profit varies from period to period and year to year. We expect cost of goods sold to decrease in absolute dollars and as a percentage of total net sales in the future, primarily due to the PSL Divestiture and as a result of the closure of the AMTC Facility and the transfer of the Sanken products distribution business to PSL.

A significant portion of our costs are fixed and, as a result, costs are generally difficult to adjust or may take time to adjust in response to changes in demand. In addition, our fixed costs increase as we expand our capacity. If we expand capacity faster than required by our sales growth, our gross margin could be negatively affected. Gross margin is calculated as gross profit divided by total net sales.

Operating Expenses

Research and development (“R&D”) expenses

R&D expenses consist primarily of personnel-related costs of our research and development organization, including stock-based compensation, costs of development of wafers and masks, license fees for computer-aided design software, costs of development testing and evaluation, costs of developing automated test programs, equipment depreciation and related occupancy and equipment costs. While most of the costs incurred are for new product development, a significant portion of these costs are related to process technology development, and proprietary package development. R&D expenses also include costs for technology development by external parties. We expect further increases in R&D expenses, in absolute dollars and as a percentage of total net sales as we continue the development of innovative technologies and processes for new product offerings as well as increase the headcount of our R&D personnel in future years.

Selling, General and Administrative (“SG&A”) expenses

SG&A expenses consist primarily of personnel-related costs, including stock-based compensation, and sales commissions to independent sales representatives, professional fees, including the costs of accounting, audit, legal, regulatory and tax compliance. Additionally, costs related to advertising, trade shows, corporate marketing, as well as an allocated portion of our occupancy costs also comprise SG&A expenses.

We anticipate our selling and marketing expenses to increase in absolute terms as we expand our sales force and increase our sales and marketing activities. We also anticipate that we will incur increased accounting, audit, legal, regulatory, compliance and director and officer insurance costs as well as investor and public relations expenses associated with being a public company.

In connection with the closing of our IPO during the third fiscal quarter of 2021, we recognized one-time stock-based compensation expense of $40.4 million, consisting of $4.1 million within cost of goods sold, $1.8 million within R&D expenses, and $34.5 million within SG&A expenses, in connection with the vesting of all outstanding shares of our Class A common stock. We also recognized one-time stock-based compensation expense of $1.6 million, consisting of $0.2 million within cost of goods sold, $0.1 million within R&D expenses, and $1.3 million within SG&A expenses, in connection with the automatic acceleration of 25% of the standard vesting term of shares of our Class L common stock at that time. In addition, we recognized one-time stock-based compensation expense of $1.0 million, consisting of $0.1 million within cost of goods sold, $0.4 million within R&D expenses, and $0.5 million within SG&A expenses, in connection with the RSU Conversion Program.

Loss on debt extinguishment

Loss on debt extinguishment represents the loss associated with the partial repayment of our Term Loan Facility on November 25, 2020.

Interest (expense) income, net

Interest (expense) income, net is comprised of interest expense from term loan debt and credit facilities we maintain with various financial institutions and previously on borrowings under the PSL-Sanken Loans (which were forgiven in connection with the PSL Divestiture). Current expense is partially mitigated by income earned on our cash and cash equivalents, consisting primarily of certain investments that have contractual maturities no greater than three months at the time of purchase.

Foreign currency transaction (loss) gain

We incur transaction gains and losses resulting from intercompany transactions as well as transactions with customers or vendors denominated in currencies other than the functional currency of the legal entity in which the transaction is recorded. The largest contributor of the foreign currency transaction (loss) gain is the result of an intercompany loan to our subsidiary that operates the AMTC Facility where at the end of each reporting period we revalue the amounts due under the loan to the U.S. Dollar.

Income in earnings of equity investment

Income in earnings of equity investment represents our equity investment in connection with the PSL Divestiture.

Other, net

Other, net primarily consists of miscellaneous income and expense items unrelated to our core operations.

Income tax (benefit) provision

Our provision for income taxes is comprised of the year to date taxes based on an estimate of the annual effective tax rate plus the tax impact of discrete items.

We are subject to tax in the U.S. and various foreign jurisdictions. Our effective tax rate can fluctuate primarily based on: the mix of our U.S. and foreign income; the impact of discrete transactions; and the difference between the amount of tax benefit generated by the foreign derived intangible income deduction (“FDII”) and research credits offset by the additional tax from the global intangible low-tax income (GILTI) and the base erosion tax (“BEAT”).

We regularly assesses the likelihood of outcomes that could result from the examination of our tax returns by the IRS, and other tax authorities to determine the adequacy of our income tax reserves and expense. Should actual events or results differ from our then-current expectations, charges or credits to our provision for income taxes may become necessary. Any such adjustments could have a significant effect on the results of operations.

Total net sales

Total net sales increased by $4.6 million, or 2.9%, to $164.4 million in the three-month period ended December 25, 2020 from $159.8 million in the three-month period ended December 27, 2019. This increase was primarily due to automotive production recovery and increased demand in industrial automation applications, partially offset by the removal of wafer foundry products and Sanken distribution products, respectively, resulting from the PSL Divestiture, more fully described below.

Sales Trends by Core End Market and Application

The following table summarizes net sales by core end market and other applications. The categorization of net sales by market is based on the characteristics of the end product and application into which our product will be designed. Other applications include wafer foundry and distribution sales unrelated to and no longer part of our core business in fiscal year 2021.

Total net sales	$	164,449	$	159,802	$	4,647	2.9	%

The increase in net sales across geographic locations in the three-month period ended December 25, 2020 compared to the three-month period ended December 27, 2019 was due primarily to an increase of $10.9 million, or 30.9%, in Greater China related to increases in automotive demand and an increase of $8.6 million, or 110.0%, in Other Asia related to continued strength in data center, other consumer, and printer applications.

Excluding the net sales of $7.7 million associated with the PSL Divestiture, net sales were up $5.0 million, or 20.4%, in the United States and Other Americas, primarily driven by an increase in demand for our core application products sold in the automotive end market. The predominant country comprising Other Americas is Mexico.

The increase in net sales of $3.9 million, or 16.0%, in Europe was primarily driven by increases in automotive demand. The predominant countries comprising Europe are Germany and France.

Revenue in Japan totaled $26.4 million in the three-month period ended December 25, 2020 compared to $29.4 million in the three-month period ended December 27, 2019, excluding net sales of $16.6 million in Japan associated with the PSL Divestiture. This decrease of $2.9 million, or 10.0%, was primarily driven by a decrease in core demand due to COVID-19.

Cost of goods sold, gross profit and gross margin

Cost of goods sold decreased by $8.3 million, or 8.4%, to $90.0 million in the three-month period ended December 25, 2020 from $98.3 million in the three-month period ended December 27, 2019. The decrease in cost of goods sold was primarily due to a $26.6 million decrease in cost of goods sold attributable to the PSL Divestiture. The offsetting $18.4 million increase in cost of goods sold was primarily attributable to increases of $4.7 million in stock-based compensation, of which $4.4 million related to the IPO and accelerated vesting of the Class A and L common stock and RSU Conversion Program, , and a combined $13.4 million of increases attributable to decreased standard margins, returns and quality and other related costs, and manufacturing cost absorptions. In addition, there were $0.3 million of Voxtel related impacts, mostly attributable to acquired intangible amortization during the period.

Gross profit increased by $12.9 million, or 21.0%, to $74.4 million in the three-month period ended December 25, 2020 from $61.5 million in the three-month period ended December 27, 2019. The increase in gross profit was driven by a $28.9 million operational increase in net sales to core end markets, partially offset by $2.3 million related to the PSL Divestiture and by the impacts to cost of goods sold discussed above.

R&D expenses

R&D expenses increased by $5.5 million, or 21.6%, to $31.0 million in the three-month period ended December 25, 2020 from $25.5 million in the three-month period ended December 27, 2019. This increase was primarily due to a $3.0

million increase in stock-based compensation, of which $2.3 million related to the IPO and accelerated vesting of the Class A and L common stock and RSU Conversion Program, and a combined $3.3 million increase in employee salaries and inventory and supplies, partially offset by a reduction of $0.8 million of expenses related to the PSL Divestiture and a $0.5 million reduction in travel and meeting costs.

R&D expenses represented 18.9% of our total net sales for the three-month period ended December 25, 2020, an increase from 15.9% of our total net sales for the three-month period ended December 27, 2019. This percentage increase was primarily due to stock-based compensation expenses recorded in the three-month period ended December 25, 2020.

SG&A expenses

SG&A expenses increased by $42.8 million, or 171.6%, to $67.7 million in the three-month period ended December 25, 2020 from $24.9 million in the three-month period ended December 27, 2019. This increase was primarily due to a $38.0 million increase in stock-based compensation expense, of which $36.3 million related to the IPO and accelerated vesting of the Class A and L common stock and RSU Conversion Program, and a combined $6.6 million of increased employee salaries, insurance and facility costs, partially offset by a reduction of $2.2 million of expenses related to the PSL Divestiture and a combined $2.3 million reduction in severance, professional fees, and travel and meeting costs.

SG&A expenses represented 41.1% of our total net sales for the three-month period ended December 25, 2020, an increase from 15.6% of our total net sales for the three-month period ended December 27, 2019. This percentage increase was primarily due to stock-based compensation expenses recorded in the three-month period ended December 25, 2020.

Loss on debt extinguishment

Loss on debt extinguishment reflected a $9.1 million loss in the three-month period ended December 25, 2020, representing the write-off of unamortized balances of previously deferred financing costs as a result of the $300.0 million Term Loan Facility principal balance repayment on November 25, 2020.

Interest (expense) income, net

Interest expense, net increased by $2.6 million in the three-month period ended December 25, 2020 compared to the three-month period ended December 27, 2019. The increase in interest expense was primarily due to mandatory interest payments on the Term Loan Facility in the three-month period ended December 25, 2020.

Foreign currency transaction (loss) gain

We recorded a foreign currency transaction loss of $0.1 million in the three-month period ended December 25, 2020 compared to a loss of $0.6 million in the three-month period ended December 27, 2019. The foreign currency transaction loss recorded in the three-month period ended December 25, 2020 was primarily due to $0.3 million of realized and unrealized losses from our UK and Philippines locations, partly offset by $0.2 million of realized and unrealized gains from our Thailand location. The currency loss recorded in the three-month period ended December 27, 2019 was primarily attributable to $1.1 million of realized and unrealized losses from our UK location and $0.6 million of realized and unrealized gains from our Thailand location.

Income in earnings of equity investment

Income in earnings of equity investment reflected a $0.9 million gain in the three-month period ended December 25, 2020, representing the earnings on our 30% investment in PSL during the three-month period ended December 25, 2020.

Other, net

Other, net increased by $0.4 million to approximately $0.5 million of loss in the three-month period ended December 25, 2020 from $0.1 million of loss in the three-month period ended December 27, 2019.

Income tax (benefit) provision

The benefit for income taxes and the effective income tax rate were $30.5 million and 85.8%, respectively, in the three-month period ended December 25, 2020 and the provision for income taxes and the effective income tax rate were $1.5 million and 14.7%, respectively, in the three-month period ended December 27, 2019. The change in effective income tax rates is primarily due to the $40.4 million IPO related stock-based compensation charge which significantly reduced U.S.

income and was included in our tax rate from operations in the three-month period ended December 25, 2020. The incremental stock-based compensation windfall was treated as a discrete tax adjustment as an incremental tax deduction in the three-month period ended December 25, 2020.

Additionally, other discrete transactions, the divestiture of Polar and the one-time dividend resulted in additional tax deductions. The reduction in U.S. income and the discrete tax deductions resulted in a U.S. tax NOL that can be carried back to refund prior years’ taxes. In total approximately $18.1 million of discrete tax benefits recorded in the three-month period ended December 25, 2020 were partially offset by a reduction in our FDII deduction and an increase in GILTI and BEAT tax.

(1)Our total net sales for the nine-month period ended December 27, 2019 also include related party net sales related to the sale of wafer foundry products to Sanken by PSL and net sales related to our distribution of Sanken products in North America, South America and Europe which, in each case, we did not recognize during the nine-month period ended December 25, 2020 and will not recognize in any future period due to our consummation of the PSL Divestiture. See our

unaudited consolidated financial statements included elsewhere in this Quarterly Report for additional information regarding our related party net sales for the periods set forth above.

Total net sales

Total net sales decreased by $59.4 million, or 12.5%, to $416.1 million in the nine-month period ended December 25, 2020 from $475.5 million in the nine-month period ended December 27, 2019. Of this decrease, $76.3 million was attributable to the PSL Divestiture, which was partially offset by increased net sales to our core end markets of $16.9 million, due primarily to increased demand in industrial automation applications and data center applications and a COVID-19-related increase in demand for printers and other peripherals.

Sales Trends by Core End Market and Application

applications include wafer foundry and distribution sales unrelated to and no longer part of our core business in fiscal year 2021.

Total net sales	$	416,099	$	475,485	$	(59,386)	(12.5)	%

Net sales to our core end markets increased by $16.9 million, or 4.2%, to $416.1 million in the nine-month period ended December 25, 2020 from $399.2 million in the nine-month period ended December 27, 2019, driven by increases in industrial of $9.6 million, or 17.1%, and other of $17.2 million, or 32.3%, and partially offset by a decline in automotive of $9.9 million, or 3.4%.

Automotive net sales decreased in the nine-month period ended December 25, 2020 compared to the nine-month period ended December 27, 2019 as our customers’ vehicle production slowed reflecting factory closures and demand uncertainty related to COVID-19.

Industrial and other net sales improved in the nine-month period ended December 25, 2020 compared to the nine-month period ended December 27, 2019 due primarily to increased demand in industrial automation applications and data center applications and a COVID-19 related increase in demand for printers and other peripherals.

Sales Trends by Product

The following table summarizes net sales by product:


	Nine-Month Period Ended				Change
	December 25, 2020		December 27, 2019		Amount		%
	(Dollars in thousands)
Power integrated circuits (“PIC”)	$	146,276	$	123,900	$	22,376	18.1	%
Magnetic sensors (“MS”)	268,956		275,275		(6,319)		(2.3)	%
Photonics	867		—		867		—	%
Wafer foundry products	—		49,622		(49,622)		—	%

Total	$	416,099	$	475,485	$	(59,386)	(12.5)	%

The decrease in net sales by product was driven by a decrease of $6.3 million in magnetic sensor IC product sales consistent with the demand weakness in automotive resulting from reductions in vehicle production related to the COVID-19 pandemic and decreases of $49.6 million and $26.7 million in net sales related to wafer foundry products and Sanken distribution products, respectively, as a result of the PSL Divestiture. These decreases were partially offset by an increase of $22.4 million in power IC product sales driven primarily by growth in data center demand, and $0.9 million in Photonics product sales resulting from the Voxtel acquisition during the period.

Sales Trends by Geographic Location

Total	$	416,099	$	475,485	$	(59,386)	(12.5)	%

The decrease in net sales across geographic locations in the nine-month period ended December 25, 2020 compared to the nine-month period ended December 27, 2019 was due primarily to wafer foundry and distribution sales totaling $76.3 million that were divested and are unrelated to and no longer a part of our core business, partially offset by automotive recovery in Asia and increased data center and other consumer and peripherals revenue growth globally.

Excluding the net sales associated with the PSL Divestiture of $26.7 million, net sales were down $7.3 million, or 9.6%, in the United States and Other Americas, primarily driven by a decrease in demand for our core application products sold in the automotive end market resulting from the factory shutdowns and demand weakness related to the COVID-19 pandemic. The predominant country comprising Other Americas is Mexico.

The decrease in net sales of $6.1 million, or 8.0%, in Europe was primarily driven by a decrease in demand for our core application products sold in the automotive end market. The predominant countries comprising Europe are Germany and France.

Revenue in Asia totaled $277.0 million in the nine-month period ended December 25, 2020 compared to $246.6 million in the nine-month period ended December 27, 2019, excluding the net sales associated with the PSL Divestiture of $49.6 million in Japan. This increase of $30.4 million, or 12.3%, was primarily driven by increases in China and Other Asia for automotive and industrial products, partially offset by a decrease in Japan related to automotive demand weakness.

Cost of goods sold, gross profit and gross margin

Cost of goods sold decreased by $61.8 million, or 21.6%, to $224.2 million in the nine-month period ended December 25, 2020 from $286.0 million in the nine-month period ended December 27, 2019. The decrease in cost of goods sold was primarily due to a $73.2 million decrease in cost of goods sold attributable to the PSL Divestiture. The additional $11.4 million increase in cost of goods sold was primarily attributable to a combined $6.2 million of increases related to standard margins, returns and quality and other costs, and manufacturing cost absorptions, as well as increases of $4.8 million in stock-based compensation, of which $4.4 million related to the IPO and accelerated vesting of the Class A and L common stock and RSU Conversion Program and $0.4 million of Voxtel- related impacts, mostly attributable to acquired intangible amortization occurring during the period.

Gross profit increased by $2.4 million, or 1.3%, to $191.9 million in the nine-month period ended December 25, 2020 from $189.5 million in the nine-month period ended December 27, 2019. The increase in gross profit was driven by a $16.9 million operational increase in net sales to core end markets, and the impacts to cost of goods sold discussed above.

R&D expenses

R&D expenses increased by $2.9 million, or 3.8%, to $80.5 million in the nine-month period ended December 25, 2020 from $77.6 million in the nine-month period ended December 27, 2019. This increase was primarily due to a $3.0 million increase in stock-based compensation expense, of which $2.3 million related to the IPO and accelerated vesting of the Class A and L common stock and RSU Conversion Program, and a combined $4.3 million increase in employee salaries, and inventory and supplies costs, partially offset by a reduction of $2.5 million of expenses related to the PSL Divestiture and a combined $1.8 million reduction in office supplies and travel and meeting costs.

R&D expenses represented 19.3% of our total net sales for the nine-month period ended December 25, 2020, an increase from 16.3% of our total net sales for the nine-month period ended December 27, 2019. This percentage increase was primarily due to stock-based compensation expenses recorded for the nine-month period ended December 25, 2020.

SG&A expenses

SG&A expenses increased by $40.7 million, or 52.1%, to $118.7 million in the nine-month period ended December 25, 2020 from $78.0 million in the nine-month period ended December 27, 2019. This increase was primarily due to $38.2 million increase in stock-based compensation expense, of which $36.3 million related to the IPO and accelerated vesting of the Class A and L common stock and RSU Conversion Program, and a combined $11.4 million increase in employee salaries, professional fees, office supplies, and corporate allocations, partially offset by a reduction of $5.8 million of expenses related to the PSL Divestiture, and a combined reduction of $5.8 million in severance and travel and meeting costs.

SG&A expenses represented 28.5% of our total net sales for the nine-month period ended December 25, 2020, an increase from 16.4% of our total net sales for the nine-month period ended December 27, 2019. This percentage increase was primarily due to stock-based compensation expenses recorded for the nine-month period ended December 25, 2020.

Loss on debt extinguishment

Loss on debt extinguishment reflected a $9.1 million loss in the nine-month period ended December 25, 2020, representing the write-off of unamortized balances of previously deferred financing costs as a result of the $300.0 million Term Loan Facility principal balance repayment on November 25, 2020.

Interest (expense) income, net

Interest expense, net increased by $1.8 million, to interest expense, net of $1.9 million in the nine-month period ended December 25, 2020 from interest expense, net of $0.1 million in the nine-month period ended December 27, 2019. The increase in interest expense was primarily due to mandatory interest payments on the Term Loan Facility in the nine-month period ended December 25, 2020.

Foreign currency transaction (loss) gain

We recorded a foreign currency transaction loss of $1.3 million in the nine-month period ended December 25, 2020 compared to a gain of $2.8 million in the nine-month period ended December 27, 2019. The foreign currency transaction loss recorded in the nine-month period ended December 25, 2020 was primarily due to $2.2 million of realized and unrealized losses from our UK location, partially offset by $1.4 million of realized and unrealized gains from our Thailand location. The foreign currency transaction gain recorded in the nine-month period ended December 27, 2019 was primarily attributable to $2.4 million and $0.4 million of realized and unrealized gains from our Thailand and UK locations, respectively.

Income in earnings of equity investment

Income in earnings of equity investment reflected a $1.4 million gain in the nine-month period ended December 25, 2020, representing the earnings on our 30% investment in PSL during the nine-month period ended December 25, 2020.

Other, net

Other, net decreased by $0.9 million to $0.3 million of loss in the nine-month period ended December 25, 2020 from $1.2 million of loss in the nine-month period ended December 27, 2019. The loss in the nine-month period ended December 27, 2019 was primarily due to expenses incurred associated with a settlement to terminate a relationship with a

distributor and disposal of equipment from the prior Worcester, Massachusetts facility that sold during the first three-month period in fiscal year 2020.

Income tax (benefit) provision

The benefit for income taxes and the effective income tax rate were $27.9 million and 150.9%, respectively, in the nine-month period ended December 25, 2020 and the provision for income taxes and the effective income tax rate were $11.7 million and 33.0%, respectively, in the nine-month period ended December 27, 2019. The change in effective income tax rates is primarily due to the $40.4 million IPO related stock-based compensation charge which significantly reduced U.S. income and was included in our tax rate from operations in the nine-month period ended December 25, 2020. The incremental stock-based compensation windfall was treated as a discrete tax adjustment as an incremental tax deduction in the nine-month period ended December 25, 2020.

Additionally, other discrete transactions, the PSL divestiture and the one-time dividend resulted in additional tax deductions. The reduction in U.S. income and the discrete tax deductions resulted in a U.S. tax NOL that can be carried back to refund prior years’ taxes. In total approximately $18.1 million of discrete tax benefits recorded in the nine-month period ended December 25, 2020 were partially offset by a reduction in our FDII deduction and an increase in GILTI and BEAT tax. In the nine-month period ended December 27, 2019, there was a discrete tax expense of approximately $5.5 million recorded for the settlement of IRS transfer pricing audits for years 2016, 2017, and 2018.

Non-GAAP Financial Measures

In addition to the measures presented in our consolidated financial statements, we regularly review other metrics, defined as non-GAAP financial measures by the SEC, to evaluate our business, measure our performance, identify trends, prepare financial forecasts and make strategic decisions. The key metrics we consider are non-GAAP Gross Profit, non-GAAP Gross Margin, non-GAAP Operating Expenses, non-GAAP Operating Income, non-GAAP Operating Margin, non-GAAP Profit before Tax, non-GAAP Provision for Income Tax, non-GAAP Net Income, non-GAAP Net Income per Share, EBITDA, Adjusted EBITDA and Adjusted EBITDA margin (collectively, “Non-GAAP Financial Measures”). These Non-GAAP Financial Measures provide supplemental information regarding our operating performance on a non-GAAP basis that excludes certain gains, losses and charges of a noncash nature or that occur relatively infrequently and/or that management considers to be unrelated to our core operations, and in the case of non-GAAP Provision for Income Tax, management believes that this non-GAAP measure of income taxes provides it with the ability to evaluate the non-GAAP Provision for Income Taxes across different reporting periods on a consistent basis, independent of special items and discrete items, which may vary in size and frequency. By presenting these Non-GAAP Financial Measures, we provide a basis for comparison of our business operations between periods by excluding items that we do not believe are indicative of our core operating performance, and we believe that investors’ understanding of our performance is enhanced by our presenting these Non-GAAP Financial Measures, as they provide a reasonable basis for comparing our ongoing results of operations. Management believes that tracking and presenting these Non-GAAP Financial Measures provides management and the investment community with valuable insight into matters such as our ongoing core operations and the underlying business trends that are affecting our performance. These Non-GAAP Financial Measures are used by both management and our board of directors, together with the comparable GAAP information, in evaluating our current performance and planning our future business activities. We believe that these Non-GAAP Financial Measures, when used in conjunction with our GAAP financial information, also allow investors to better evaluate our financial performance in comparison to other periods and to other companies in our industry.

These Non-GAAP Financial Measures have significant limitations as analytical tools. Some of these limitations are that:

•such measures do not reflect our cash expenditures, or future requirements for capital expenditures or contractual commitments;

•such measures exclude certain costs which are important in analyzing our GAAP results;

•such measures do not reflect changes in, or cash requirements for, our working capital needs;

•such measures do not reflect the interest expense, or the cash requirements necessary to service interest or principal payments on our debt;

•such measures do not reflect our tax expense or the cash requirements to pay our taxes; although depreciation and amortization are noncash charges excluded from our non-GAAP results, the assets being depreciated and amortized will often have to be replaced in the future;

•such measures do not reflect any cash requirements for such replacements; and

•other companies in our industry may calculate such measures differently than we do, thereby further limiting their usefulness as comparative measures.

These Non-GAAP Financial Measures are supplemental measures of our performance that are neither required by, nor presented in accordance with, GAAP. These Non-GAAP Financial Measures should not be considered as substitutes for GAAP financial measures such as gross profit, gross margin, net income or any other performance measures derived in accordance with GAAP. Also, in the future we may incur expenses or charges such as those added back in the calculation of these Non-GAAP Financial Measures. Our presentation of these Non-GAAP Financial Measures should not be construed as an inference that future results will be unaffected by unusual or nonrecurring items.

Our prior disclosure referred to non-GAAP Gross Profit and non-GAAP Gross Margin as Adjusted Gross Profit and Adjusted Gross Margin, respectively. No changes have been made to how we calculate these measures.

Non-GAAP Gross Profit and Non-GAAP Gross Margin

We calculate non-GAAP Gross Profit and non-GAAP Gross Margin excluding the items below from cost of goods sold in applicable periods. We calculate non-GAAP Gross Margin as non-GAAP Gross Profit divided by total net sales.

•PSL and Sanken Distribution Agreement – Represents the elimination of inventory cost amortization and foundry service payment related to one-time costs incurred in connection with the PSL Divestiture.

•Stock-based compensation – Represents noncash expenses arising from the grant of stock awards.

•AMTC Facility consolidation one-time costs – Represents one-time costs incurred in connection with closing of the AMTC Facility and transitioning of test and assembly functions to the AMPI Facility announced and initiated in fiscal year 2020, consisting of moving equipment between facilities, contract terminations and other non-recurring charges. The closure and transition of the AMTC Facility is expected to be substantially complete by the end of March 2021. These costs are in addition to, and not duplicative of, the adjustments noted in note (*) below.

•Amortization of acquisition-related intangible assets – Represents noncash expenses associated with the amortization of intangible assets in connection with the acquisition of Voxtel, Inc., which closed in August 2020.

•COVID-19 related expenses – Represents expenses attributable to the COVID-19 pandemic primarily related to increased purchases of masks, gloves and other protective materials, and overtime premium compensation paid for maintaining 24-hour service at the AMPI Facility.

(*) Non-GAAP Gross Profit and the corresponding calculation of non-GAAP Gross Margin in this release do not include adjustments consisting of:

•Additional AMTC related costs – Represents costs related to the closing of the AMTC Facility and the transitioning of test and assembly functions to the AMPI Facility in the Philippines announced in fiscal year 2020 consisting of: the net savings expected to result from the capacity transition to the AMPI Facility, which facility had duplicative capacity based on the buildouts of the AMPI Facility in fiscal years 2019 and 2018. The elimination of these costs did not reduce our production capacity and therefore did not have direct effects on our ability to generate revenue. The closure and transition of the AMTC Facility is expected to be substantially complete by the end of March 2021.

•Out of period adjustment for depreciation expense of giant magnetoresistance assets (“GMR assets”) – Represents a one-time depreciation expense related to the correction of an immaterial error, related to 2017, for certain manufacturing assets that have reached the end of their useful lives.

•Labor savings – Represents salary and benefit costs related to employees whose positions were eliminated through voluntary separation programs or other reductions in force (not associated with the closure of the AMTC Facility or any other plant or facility) and a restructuring of overhead positions from high-cost to low-cost jurisdictions net of costs for newly hired employees in connection with such restructuring.

Non-GAAP Operating Expenses, non-GAAP Operating Income and non-GAAP Operating Margin

We calculate non-GAAP Operating Expenses and non-GAAP Operating Income excluding the same items excluded above to the extent they are classified as operating expenses, and also excluding the items below in applicable periods. We calculate non-GAAP Operating Margin as non-GAAP Operating Income divided by total net sales.

•Transaction fees – Represents transaction-related legal and consulting fees incurred primarily in connection with (i) the unsuccessful acquisition of a competitor in fiscal year 2019, (ii) the acquisition of Voxtel, Inc. in fiscal year

2020, and (iii) the PSL Divestiture and the transfer of the Sanken products distribution business to PSL in fiscal year 2020.

•Severance – Represents severance costs associated with (i) labor savings initiatives to manage overall compensation expense as a result of the declining sales volume during the applicable period, including a voluntary separation incentive payment plan for employees near retirement and a reduction in force and (ii) the closing of the AMTC Facility and the transitioning of test and assembly functions to the AMPI Facility announced and initiated in fiscal year 2020.

EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin

We calculate EBITDA as net income minus interest income (expense), tax provision, and depreciation and amortization expenses. We calculate Adjusted EBITDA as EBITDA excluding the same items excluded above and also excluding the items below in applicable periods. We calculate Adjusted EBITDA Margin as Adjusted EBITDA divided by total net sales.

•Non-core (gain) loss on sale of equipment – Represents non-core miscellaneous losses and gains on the sale of equipment.

•Miscellaneous legal judgment charge – Represents a one-time charge associated with the final payment of the previously accrued amount payable with respect to a VAT dispute related to the construction of the AMPI Facility.

•Foreign currency translation loss (gain) – Represents losses and gains resulting from the remeasurement and settlement of intercompany debt and operational transactions, as well as transactions with external customers or vendors denominated in currencies other than the functional currency of the legal entity in which the transaction is recorded.

•Income in earnings of equity investment – Represents our equity method investment in PSL.

•Inventory cost amortization – Represents intercompany inventory transactions incurred from purchases made from PSL in fiscal year 2020. Such costs are one-time incurred expenses impacting our operating results during fiscal year 2021 following the PSL Divestiture. Such costs are not expected to have a continuing impact on our operating results after our second fiscal quarter of fiscal year 2021.

•Foundry service payment – Represents foundry service payments incurred under our Price Support Agreement with PSL in respect to the guaranteed capacity at PSL to support our production forecast and are one-time costs incurred impacting our operating results during fiscal year 2021 following the PSL Divestiture. Such costs are not expected to have a continuing impact on our operating results after fiscal year 2021.

Non-GAAP Profit before Tax

Liquidity and Capital Resources

As of December 25, 2020, we had $157.7 million of cash and cash equivalents and $289.4 million of working capital compared to $214.5 million of cash and cash equivalents and $298.1 million of working capital as of March 27, 2020. Working capital is impacted by the timing and extent of our business needs.

Our primary requirements for liquidity and capital are working capital, capital expenditures, principal and interest payments on our outstanding debt and other general corporate needs. Historically, these cash requirements have been met through cash provided by operating activities and cash and cash equivalents. In March 2020, we borrowed an aggregate of $43.0 million under our revolving credit facilities (including $10.0 million that was borrowed by PSL under its revolving credit facility (the “PSL Revolver”)), representing substantially all of our available capacity, in order to increase our cash position and help maintain financial flexibility in light of the continued uncertainty surrounding the COVID-19 pandemic. Of this $43.0 million, the $10.0 million of debt borrowed under the PSL Revolver is the obligation of PSL and was no longer included on our consolidated balance sheet as of December 25, 2020. In addition, the proceeds from such borrowings were retained by PSL and are no longer available for use by us following the consummation of the PSL Divestiture.

On September 30, 2020, we entered into a term loan credit agreement with Credit Suisse AG, Cayman Islands Branch, as administrative agent and collateral agent, and the other agents, arrangers and lenders party thereto, providing for a $325.0 million senior secured term loan facility. On September 30, 2020, we also entered into a revolving facility credit agreement with Mizuho Bank, Ltd., as administrative agent and collateral agent, and the other agents, arrangers and lenders party thereto, providing for a $50.0 million senior secured revolving credit facility. In connection with entering into the revolving credit facility, we used cash on hand to repay all amounts outstanding under the AML Revolver in the amount of $25.0 million with Mizuho Bank, Ltd. and AML’s $8.0 million line of credit agreement with the Bank of Mitsubishi UFJ, and terminated all commitments thereunder. On November 25, 2020, we repaid $300.0 million of the outstanding $325.0 million Term Loan Facility using proceeds from our recently completed IPO.

We anticipate a significant increase in accounting, legal and professional fees and other costs associated with being a public company. We believe that our existing cash resources, together with the proceeds from our IPO and our access to the capital markets, will be sufficient to finance our continued operations, growth strategy, planned capital expenditures and the additional expenses we expect to incur as a public company for at least the next 12 months. If these resources are not sufficient to satisfy our liquidity requirements, we may be required to seek additional financing. If we raise additional funds by issuing equity securities, our stockholders will experience dilution. Debt financing, if available, may contain covenants that significantly restrict our operations or our ability to obtain additional debt financing in the future. Any additional financing that we raise may contain terms that are not favorable to us or our stockholders. We cannot assure you that we would be able to obtain additional financing on terms favorable to us or our existing stockholders, or at all.

Cash Flows from Operating, Investing and Financing Activities

The following table summarizes our cash flows for the nine-month periods ended December 25, 2020 and December 27, 2019:


	Nine-Month Period Ended
	December 25, 2020		December 27, 2019
	(dollars in thousands)
Net cash provided by operating activities	$	63,534	$	48,770

Effect of exchange rate changes on cash and cash equivalents	3,350		(6,452)
Net (decrease) increase in cash and cash equivalents and restricted cash	$	(55,703)	$	41,257

Operating Activities

Net cash provided by operating activities was $63.5 million in the nine-month period ended December 25, 2020, resulting primarily from our net income of $9.4 million and noncash charges of $79.0 million, partially offset by a net increase in operating assets and decrease in operating liabilities of $24.9 million. Net changes in operating assets and liabilities consisted of a $29.7 million increase in prepaid expenses, a $6.0 million increase in trade accounts receivable, net and a $1.2 million decrease in accrued expenses and other current and long-term liabilities, partially offset by a $8.3 million decrease in net amounts due from related parties, a $2.4 million increase in trade accounts payable, a $1.1 million decrease in inventories and a $0.1 million decrease in accounts receivable – other. The increase in prepaid expenses and other assets, excluding the impact of the noncash removal of PSL-related assets of $5.2 million and the acquisition of Voxtel, included an $18.7 million increase in prepaid taxes, a $3.6 million increase in VAT receivables, a $3.5 million increase in prepaid insurance and a $2.8 million increase in amortizable patent costs. Changes related to trade accounts receivable, net, accounts

receivable – other, and due from/to related parties were primarily due to variations in the timing of such payments in the ordinary course of business. The decrease in accrued expenses and other current and long-term liabilities is the result of a $14.9 million increase in balances from March 27, 2020, adjusted for $26.5 million of noncash increases related to the Voxtel acquisition primarily for deferred and contingent consideration, offset by the $7.6 million impact of the noncash removal of PSL and Sanken distribution related assets. Trade accounts payable were impacted by the noncash removal of PSL-related liabilities of $4.2 million, with the difference due to timing of such payments in the ordinary course of business. The $1.1 million inventory increase is the result of a $33.2 million reduction in balances from March 27, 2020, offset by a $32.3 million impact of the noncash removal of PSL and Sanken distribution business related assets and $3.0 million of noncash inventory provisions, reduced by $3.1 million of inventory added in the acquisition of Voxtel.

Net cash provided by operating activities was $48.8 million in the nine-month period ended December 27, 2019, resulting primarily from our net income of $23.8 million and noncash charges of $52.4 million, partially offset by a net increase in operating assets and decrease in liabilities of $27.4 million. The net changes in operating assets and liabilities consisted of a $21.0 million increase in net amounts due from related parties, a $17.3 million decrease in accrued expenses and other current and long-term liabilities, a $6.2 million increase in prepaid expenses and other assets and a $0.3 million increase in inventories. These decreases to cash were partially offset by a $15.5 million decrease in trade accounts receivable, a $1.1 million increase in trade accounts payable and a $0.7 million decrease in accounts receivable – other. The increase in net amounts due from related parties, trade accounts payable, and the decrease in accounts receivable-other was primarily due to variations in the timing of such payments in the ordinary course of business. The decrease in accrued expenses and other current and long-term liabilities was primarily the result of the payment of $14.5 million in incentive plans and an aggregate net decrease to accrued and other liabilities of $2.8 million, which includes a partial offset of a net increase in certain accrued tax accounts in the amount of $3.7 million primarily related to a fiscal year 2020 IRS settlement for a transfer pricing agreement with PSL. The increase in inventories was a result of reduced sales and was partially offset by a noncash impact of $2.5 million of inventory provisions during the period. The decrease in trade accounts receivable, net was primarily a result of decreased sales year-over-year during the comparable periods and includes $0.8 million of noncash bad debt provisions.

Investing Activities

Net cash used in investing activities primarily consists of purchases and sales of property, plant and equipment, partially offset by proceeds from sales of property, plant and equipment. We expect our multi-year transition from an integrated device manufacturer to our current fabless, asset-lite manufacturing model, including the completion of the PSL Divestiture following the end of fiscal year 2020, will result in a decrease in capital expenditures in the future.

Net cash used in investing activities was $50.4 million in the nine-month period ended December 25, 2020, consisting of $25.9 million of purchases of property, plant and equipment, $8.5 million of cash expended for the acquisition of Voxtel and $16.3 million of cash removed as a result of the PSL Divestiture, partially offset by $0.3 million of proceeds from sales of property, plant and equipment.

Net cash used in investing activities was $31.1 million in the nine-month period ended December 27, 2019, consisting of $35.0 million of purchases of property, plant and equipment, partially offset by $3.9 million of proceeds obtained from the sale of property, plant and equipment. The $3.9 million of proceeds from sales of property, plant and equipment were primarily attributable to the sale of our Worcester, Massachusetts facility (the “Worcester Facility”) in the first quarter of fiscal 2020.

Financing Activities

Net cash used in financing activities was $72.2 million in the nine-month period ended December 25, 2020, consisting of $400.0 million of dividends paid prior to our IPO, $300.0 million for repayment of senior secured debt, $27.7 million of payments for taxes related to net share settlement of equity awards, and $33.0 million for repayment of unsecured credit facilities, partially offset by $315.7 million of borrowing of senior secured debt, net of deferred financing costs, $321.4 million of proceeds from initial public offering, net of underwriting discounts and other offering costs, and a $51.4 million related party note receivable.

Net cash provided by financing activities was $30.0 million in the nine-month period ended December 27, 2019, consisting of a repayment of the $30.0 million short-term loan issued to Sanken in the fourth quarter of fiscal year 2019.

Debt Obligations

As of December 25, 2020, we had $25.0 million in aggregate principal amount of debt outstanding under our Senior Secured Credit Facilities. We entered into the Senior Secured Credit Facilities on September 30, 2020 consisting of a $325.0 million Term Loan Facility due in 2027 and a revolving facility credit agreement providing for a $50.0 million Revolving Credit Facility expiring in 2023. On November 25, 2020 we repaid $300.0 million of the outstanding Term Loan Facility principal balance.

Description of Credit Facilities

Term Loan Facility

The Term Loan Facility bears interest at a rate per year of, at our option, either (i) the Base Rate plus an applicable margin from 2.75% to 3.00% depending on our net leverage ratio, or (ii) the Eurodollar Rate plus an applicable margin from 3.75% to 4.00% depending on our net leverage ratio. The Eurodollar Rate is subject to a floor of 0.50%. At December 25, 2020 all term loan borrowings were designated as Eurodollar loans and bore interest of 4.50%.

We incurred deferred financing costs of $9.4 million in connection with the Term Loan Facility, the total of which was amortized into interest expense or recognized as loss on debt extinguishment as of December 25, 2020.

The Term Loan Facility contains certain covenants that may, among other things and subject to certain exceptions, restrict the ability of us to:

•create, incur, assume or suffer to exist any Lien upon any of its property, assets, or revenue;

•create, incur, or assume indebtedness;

•merge, consolidate or amalgamate with or into any other entity;

•purchase or otherwise acquire all or substantially all of the assets, liabilities or properties of any other entity;

•sell, lease, transfer or otherwise dispose of all or substantially all of its assets or properties;

•enter into transactions with affiliates;

•Pay dividends or make other distributions;

•change the nature of its business activities, its fiscal year, or its governing documents.

Borrowings under the Term Loan Facility are secured by 100% of the stock of our domestic subsidiaries, portions of the stock of certain of our foreign subsidiaries, and substantially all of our and our subsidiaries’ other property and assets, in each case subject to various exceptions.

We may be required to make mandatory prepayments of the Term Loan Facility if we have Excess Cash Flow, as defined in the credit agreement, if we make certain sales of assets outside the ordinary course of business, or if we suffer certain property loss events. We may make optional prepayments from time to time without premium or penalty.

Revolving Credit Facility

The Revolving Credit Facility bears interest at a rate per year of, at our option, the Base Rate plus 1.5%, the Cost of Funds Rate plus 2.5%, or the Eurodollar Rate plus 2.5%. In addition, commencing on the last business day of December 2020, we are required to pay, on a quarterly basis, a non-refundable commitment fee of 0.50% per year on the average daily unused commitments under the Revolving Credit Facility.

We incurred financing costs of $0.3 million in connection with the Revolving Credit Facility, which we classified the related short-term and long-term portions within “Prepaid expenses and other current assets” and “Other assets” on our unaudited consolidated balance sheet, and are amortizing these costs over the term of the facility. The unamortized portion of the deferred financing costs associated with the Revolving Credit Facility was $0.3 million at December 25, 2020.

The Revolving Credit Facility contains certain financial and non-financial covenants, including a maximum net leverage ratio applicable to the Revolving Credit Facility in the event that utilization exceeds 35% of the revolving loan commitment.

Borrowings under the Revolving Credit Facility are secured by 100% of the stock of our domestic subsidiaries, portions of the stock of certain of our foreign subsidiaries, and substantially all of our subsidiaries’ other property and assets, in each case subject to various exceptions.

AML Revolver

On January 22, 2019, AML entered into a revolving credit agreement with Mizuho Bank, Ltd., as lender, that provided for a revolving credit facility with a maximum borrowing capacity of $25.0 million (the “AML Revolver”). On January 22, 2020, AML and the lender amended the AML Revolver to extend the termination date for commitments thereunder from January 22, 2020 to January 22, 2021 (the “Commitment Termination Date”). On September 30, 2020, we repaid the AML Revolver in full and in conjunction, terminated it.

Borrowings under the AML Revolver bore interest at a rate per year equal to, at AML’s option, either (i) LIBOR (defined, with respect to the applicable interest period, as the rate per year determined by the lender for making or maintaining such loan at approximately 11:00 a.m. London time on the day that was two London business days prior to the commencement of the applicable interest period), or (ii) the Cost of Funds Rate (defined, with respect to the applicable interest period, as the rate per year determined by the lender to be its effective cost of funding such loan in dollars during such interest period), plus, in each case, a spread of 0.4%. In addition, AML was required to pay, on a quarterly basis in arrears, a non-refundable commitment fee of 0.2% per year on the average daily unused commitments under the AML Revolver during such quarterly period. AML was also required to pay, on the closing date of the AML Revolver, a non-refundable up-front fee of $25 thousand.

The outstanding principal amount of borrowings under the AML Revolver, together with all accrued and unpaid interest thereon, was due and payable on the first to occur of (i) the last day of the applicable interest period, or (ii) the Commitment Termination Date (or, in each case, such earlier date as such borrowings are accelerated or commitments under the AML Revolver are otherwise terminated in accordance with the terms thereof).

AML was permitted to prepay all or any portion of the borrowings outstanding under the AML Revolver from time to time without premium or penalty, provided that any partial prepayment must have been in an aggregate amount not less than $100,000 or an integral multiple thereof, and all prepayments must have been accompanied by accrued and unpaid interest on the amount being prepaid to the date of such prepayment. Amounts prepaid under the AML Revolver may have been subsequently re-borrowed, provided that such prepayment was not accompanied by a termination of the underlying commitment.

Obligations under the AML Revolver were not secured by collateral. The credit agreement governing the AML Revolver contains certain covenants that, among other things and subject to certain exceptions, restricted the ability of AML to:

•merge, consolidate or amalgamate with or into any other entity;

•purchase or otherwise acquire all or substantially all of the assets, liabilities or properties of any other entity;

•sell, lease, transfer or otherwise dispose of all or substantially all of its assets or properties;

•change the nature of its business activities;

•enter into transactions with affiliates; and

•amend its governing documents.

The credit agreement also contained a financial covenant that required AML to maintain positive consolidated income before income taxes and consolidated net income for each of its fiscal years.

The credit agreement governing the AML Revolver contained certain customary representations and warranties and affirmative covenants. In addition, the lender would have been permitted to accelerate all outstanding borrowings and other obligations, terminate outstanding commitments and exercise other specified remedies upon the occurrence of certain events of default (subject to certain grace periods and exceptions), which included, among other things, payment defaults, breaches of representations and warranties, covenant defaults, cross-accelerations to material debt, certain events of bankruptcy and insolvency, and certain judgments, changes in control and material adverse effects.

AML Line of Credit

AML had a line of credit with the Bank of Mitsubishi UFJ that provided for a maximum borrowing capacity of $8.0 million at an interest rate of 1.9%. On October 1, 2020, we repaid this line of credit in full and in conjunction, terminated it.

AMPI Credit Facilities

On November 26, 2019, AMPI entered into a line of credit agreement with Union Bank of the Philippines, Inc. that provides for a maximum borrowing capacity of 60.0 million Philippine pesos (approximately $1.2 million) at the bank’s prevailing interest rate. The line of credit expires on August 31, 2021.

On November 20, 2019, AMPI entered into a line of credit agreement with BDO Unibank that provides for a maximum borrowing capacity of 75.0 million Philippine pesos (approximately $1.6 million) at the bank’s prevailing interest rate. The line of credit expires on June 30, 2021.

Off-Balance Sheet Arrangements

As of December 25, 2020, we did not have any off-balance sheet arrangements, as defined by applicable regulations of the SEC, that have had or are reasonably likely to have a current or future material effect on our financial condition, results of operations, liquidity, capital expenditures or capital resources.

Recent Accounting Pronouncements

See Note 2, “Summary of Significant Accounting Policies,” in the unaudited consolidated financial statements included elsewhere in this Quarterly Report for a full description of recent accounting pronouncements, including the respective dates of adoption or expected adoption and effects on our condensed consolidated financial statements contained in Item 1 of this Quarterly Report.

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 rates risk associated with our cash and cash equivalents and our debt, foreign currency risk and impact of inflation. We do not engage in speculative trading activities. The following analysis provides additional information regarding these risks.

Interest Rate Risk

Our investments have limited exposure to market risk. At December 25, 2020, we maintained a portfolio of cash and cash equivalents, consisting primarily of money market funds. None of these investments have a maturity date in excess of one year. Certain interest rates are variable and fluctuate with current market conditions. Because of the short-term nature of these instruments, we would not expect a sudden change in market interest rates to have a material impact on our financial condition or results of operations.

We are also exposed to market risk as a result of increases or decreases in the amount of interest expense we must pay on our Term Loan Facility and borrowings on our bank credit facilities. Although our Term Loan Facility and credit facilities have variable rates, as of December 25, 2020, we do not believe that a 10% change in market interest rates would have a material impact on our financial position or results of operations.

Foreign Currency Risk

Due to our international operations, a significant portion of our cost of sales and operating expenses is denominated in currencies other than the U.S. Dollar, principally the Euro, the Philippine Peso and the Thai Baht. As a result, our international operations give rise to transactional market risk associated with exchange rate movements of the U.S. Dollar, the Euro, the Philippine Peso and the Thai Baht. Losses on foreign exchange transactions totaled $0.1 million and $1.3 million for the three- and nine-month periods ended December 25, 2020, respectively. Losses on foreign exchange transactions amounted to $0.6 million for the three-month period ended December 27, 2019, and gains on foreign exchange transactions amounted to $2.8 million for the nine-month period ended December 27, 2019. Management does not attempt to minimize these exposures.

In addition, we are exposed to foreign currency translation risk for those subsidiaries whose functional currency is not the U.S. Dollar as changes in the value of their functional currency relative to the U.S. Dollar can adversely affect the

translated amounts of our sales, expenses, net income, assets and liabilities. This can, in turn, affect the reported value and relative growth of sales and net income from one period to the next. In addition, changes in the translated value of assets and liabilities due to changes in functional currency exchange rates relative to the U.S. Dollar result in foreign currency translation adjustments that are a component of other comprehensive income or loss. Foreign currency derivative instruments can be used to hedge exposures and reduce the risks of certain foreign currency transactions; however, these instruments provide only limited protection and can carry significant cost. We have no foreign currency derivative instrument hedges as of December 25, 2020. We will continue to analyze our exposure to currency exchange rate fluctuations and may engage in financial hedging techniques in the future to attempt to minimize the effect of these potential fluctuations. Exchange rate fluctuations may adversely affect our financial results in the future.

Impact of Inflation

Inflationary factors, such as increases in overhead costs or the costs of other core operating resources, may adversely affect our operating results. While it is difficult to accurately measure the impact of inflation due to the imprecise nature of the estimates required, we do not believe the effects of inflation, if any, on our historical results of operations and financial condition have been material. We cannot assure that future inflationary or other cost pressures will not have an adverse impact on our results of operations and financial condition in the future.

Item 4. Controls and Procedures.

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Senior Vice President, Chief Financial Officer and Treasurer (our principal executive officer and principal financial officer, respectively), evaluated the effectiveness of our disclosure controls and procedures as of December 25, 2020. Based on the evaluation of our disclosure controls and procedures as of December 25, 2020, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15(d)-15(f) under the Exchange Act) that occurred during the period covered by this Quarterly Report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

From time to time, we may be involved in claims and proceedings arising in the course of our business. The outcome of any such claims or proceedings, regardless of the merits, is inherently uncertain. We are not currently party to any material legal proceedings, and we are not aware of any pending or threatened legal proceeding against us that we believe could have a material adverse effect on our business, operating results, cash flows or financial condition.

Item 1A. Risk Factors.

Our business, financial condition and operating results can be affected by a number of factors, whether currently known or unknown, including but not limited to those described in the section titled “Risk Factors” of the Registration Statement and described elsewhere in this Quarterly Report, any one or more of which could, directly or indirectly, cause our actual financial condition and operating results to vary materially from past, or from anticipated future, financial condition and operating results. Any of these factors, in whole or in part, could materially and adversely affect the Company’s business, financial condition, operating results and stock price. For a discussion of our potential risks and uncertainties, see the risk factors previously disclosed in the section titled “Risk Factors” of our Registration Statement, which risk factor section is incorporated herein by reference.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

On October 28, 2020, the SEC declared effective our Registration Statement on Form S-1 (File No. 333-249348), as amended, filed in connection with our IPO (the “IPO Registration Statement”). Pursuant to the IPO Registration Statement, we registered the offer and sale of 25,000,000 shares of our common stock with an aggregate offering price of $350.0 million. Barclays Capital Inc., Credit Suisse Securities (USA) LLC, Wells Fargo Securities, LLC, Jefferies LLC, Mizuho Securities USA LLC, Needham & Company, LLC and SMBC Nikko Securities America, Inc. served as underwriters for the offering. On November 2, 2020, we issued and sold 25,000,000 shares of our common stock, at a price to the public of $14.00 per share. Upon completion of the IPO on November 2, 2020, we received net proceeds of approximately $321.4 million, after deducting the underwriting discount of $20.1 million and offering expenses of $8.4 million. No payments for such expenses were made directly or indirectly to (i) any of our officers or directors or their associates, (ii) any persons owning 10% or more of any class of our equity securities or (iii) any of our affiliates.

The offering terminated after the sale of all securities registered pursuant to the IPO Registration Statement. $300.0 million of the net proceeds of approximately $321.4 million from our IPO was used to repay borrowings under our term loan credit facility, and the remainder of the net proceeds were invested in short-term, investment-grade instruments. There has been no material change in the expected use of the net proceeds from our IPO as described in the final prospectus relating to our IPO Registration Statement, filed with the SEC on October 30, 2020 pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended.
