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 the 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” in this Quarterly Report and Part II, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended March 26, 2021 (the “2021 Annual 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;
2

•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.

ALLEGRO MICROSYSTEMS, INC.
Notes to Unaudited Condensed Consolidated Financial Statements – (continued)
(Amounts in thousands, except share and per share amounts)
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 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 (“U.S. GAAP”) 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 Annual Report on Form 10-K filed with the SEC on May 19, 2021 (the “2021 Annual Report”). 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”). Refer to Note 1, “Nature of Business and Basis of Presentation” to the Company’s 2021 Annual Report for details.
Financial Periods
The Company’s first quarter three-month period is a 13-week period ending on the Friday closest to the last day in June. The Company’s first quarter of fiscal 2022 ended June 25, 2021, and the Company’s first quarter of fiscal 2021 ended June 26, 2020.
2. Summary of Significant Accounting Policies
Use of Estimates
The preparation of consolidated financial statements in conformity with U.S. 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.
Reclassifications
Certain reclassifications have been made to prior-period amounts to conform to current-period reporting classifications.
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.
As of June 25, 2021 and March 26, 2021, Sanken Electric Co., Ltd. (“Sanken”) accounted for 23.2% and 22.7% 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.

(Amounts in thousands, except share and per share amounts)
For the three months ended June 25, 2021 and June 26, 2020, Sanken accounted for 18.8% and 20.5% of total net sales, respectively. No other customers accounted for 10% or more of total net sales for either of the three months ended June 25, 2021 or June 26, 2020.
During the three months ended June 25, 2021, sales from customers located outside of the United States accounted for, in the aggregate, 85.7% of the Company’s total net sales, with Greater China accounting for 22.7%, Japan accounting for 18.8% and South Korea accounting for 11.7%. No other countries accounted for greater than 10% of total net sales for the three months ended June 25, 2021.
During the three months ended June 26, 2020, sales from customers located outside of the United States, in the aggregate, accounted for 88.7% of the Company’s total net sales, with Greater China accounting for 27.9%, Japan accounting for 20.5% and South Korea accounting for 11.8%. No other countries accounted for greater than 10% of total net sales for the three months ended June 26, 2020.
Recently Adopted 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 Accounting Standards Update (“ASU”) 2016‑02, “Leases (Topic 842)” (“ASU 2016-02”), which is codified as Accounting Standard Codification (“ASC”) Topic 842 (“ASC 842”) and replaces ASC Topic 840, Leases (“ASC 840”). ASU 2016-02 and all subsequent amendments amends various aspects of existing guidance for leases and requires significant additional quantitative and qualitative disclosures about lease arrangements. ASU 2016-02 requires lessees to recognize lease assets representing the right to use an underlying asset and lease liabilities representing the obligation to make lease payments over the lease term, measured on a discounted basis, for substantially all leases. ASU 2016-02 retains a distinction between finance leases and operating leases using classification criteria that is substantially similar to the previous lease guidance. Although the Company has elected to opt-in to the extended transition dates for new or revised accounting standards to align with nonpublic companies, the Company elected to early adopt ASU 2016-02 effective March 27, 2021. The Company used the optional transition method to the modified retrospective approach, which eliminates the requirement to restate the prior period financial statements. Under this transition provision, the Company has applied ASU 2016-02 to reporting periods beginning on March 27, 2021, while prior periods continue to be reported and disclosed in accordance with the legacy guidance under ASC 840.
A number of practical expedients and policy elections are available under the new guidance to reduce the burden of adoption and ongoing compliance with ASC 842. The Company elected the “package of practical expedients”, which permitted the Company to retain lease classification and initial direct costs for any identified leases that existed prior to adoption of ASC 842. Under this transition guidance, the Company also did not reassess whether any existing contracts at March 27, 2021 are or contain leases and carried forward its initial determination under legacy lease guidance. The Company has elected not to adopt the “hindsight” practical expedient and, therefore, will measure the right-of-use (“ROU”) asset and lease liability using the remaining portion of the lease term at adoption on March 27, 2021.
The Company made an accounting policy election available under the new lease standard to not recognize lease assets and lease liabilities for leases with a term of 12 months or less. For all other leases, the initial measurement of the lease liability is based on the present value of future lease payments over the lease term at the application date or the commencement date of the lease. Lease payments may include fixed rent escalation clauses or payments that depend on an index or a rate (such as the consumer price index) measured using the index or applicable rate at lease commencement. Subsequent changes in the index or rate and any other variable payments, such as market-rate base rent adjustments, are recognized as variable lease expense in the period incurred. Payments for terminating a lease are included in lease payments only when it is probable they will be incurred. To determine the present value of lease payments, the Company uses its incremental borrowing rate, as the leases generally do not have a readily determinable implicit discount rate. The Company applies judgment in assessing factors such as Company-specific credit risk, lease term, nature and quality of the underlying collateral, currency and economic environment in determining the lease-specific incremental borrowing rate. The carrying value of the ROU assets at the application date equals the lease liability adjusted for any initial direct costs incurred and lease payments made at or before the commencement date and for any lease incentives.

Notes to Unaudited Condensed Consolidated Financial Statements – (continued)
(Amounts in thousands, except share and per share amounts)
The Company’s leases generally include a non-lease component representing additional services transferred to the Company. The Company has made an accounting policy election to account for lease and non-lease components in its contacts as a single lease component for all asset classes. The non-lease components are usually variable in nature and recorded in variable lease expense in the period incurred.
Adoption of ASC 842 resulted in ROU assets of $18,403 and lease liabilities of $18,759 related to the Company’s operating leases at March 27, 2021. The Company does not have any leases classified as finance leases. The adoption of ASC 842 did not materially impact the Company’s consolidated net income or consolidated cash flows and did not result in a cumulative-effect adjustment to the opening balance of retained earnings.
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. The Company adopted ASU 2016-13 effective March 27, 2021 and concluded that the standard update did not have a material impact on either the financial position, results of operations, cash flows, or related disclosures. There was no impact on beginning balance retained earnings upon adoption of this ASU.
The Company is exposed to credit losses primarily through trade and other financing receivables arising from revenue transactions. The Company uses an aging schedule method to estimate current expected credit losses based on days of delinquency, including information about past events and current economic conditions. The Company’s accounts receivable is separated int o two categories using a portfolio methodology to evaluate the allowance under the CECL impairment model based on sales categorization and similar credit quality and worthiness of the customers: original equipment manufacturers (“OEMs”) and distributors. The receivables in each category share similar risk characteristics. The change to the CECL impairment model resulted in an immaterial increase in the provision for expected credit losses compared to the allowance for doubtful accounts under the previous incurred loss method.
The Company increases the allowance for expected credits losses when the Company determines all or a portion of a receivable is uncollectible. The Company recognizes recoveries as a decrease to the allowance for expected credit losses. For the three-month period ended June 25, 2021, no material changes in the allowance occurred.
Recently Issued Accounting Standards Not Yet Adopted
In May 2021, the FASB issued ASU No. 2021-04, Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2021-04”). ASU 2021-04 outlines how an entity should account for modifications made to equity-classified written call options, including stock options and warrants to purchase the entity’s own common stock. The guidance in the ASU requires an entity to treat a modification of an equity-classified written call options that does not cause the option to become liability-classified as an exchange of the original option for a new option. This guidance applies whether the modification is structured as an amendment to the terms and conditions of the equity-classified written call option or as termination of the original option and issuance of a new option. The guidance is effective prospectively for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted, including in an interim period as of the beginning of the fiscal year that includes that interim period. The Company is currently in the process of evaluating the impact of this new guidance on the consolidated financial statements and the related disclosures.
3. Revenue from Contracts with Customers
The Company generates revenue from the sale of magnetic sensor integrated circuits (“ICs”) and application-specific analog power semiconductors. The following tables summarize net sales disaggregated by application, by product and by geography for the three months ended June 25, 2021 and June 26, 2020. The categorization of net sales by 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.

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 three months of fiscal years 2022 or 2021.
As of June 25, 2021, annual amortization expense of intangible assets for the next five fiscal years is expected to be as follows:

11. Leases
The Company determines if an arrangement is or contains a lease at inception, which is the date on which the terms of the contract are agreed to and the agreement creates enforceable rights and obligations. The Company also considers whether its service arrangements include the right to control the use of an asset.
The Company leases real estate, equipment and vehicles under operating lease agreements that have initial terms ranging from 1 to 11 years. The Company does not have any leases classified as finance leases. Some leases include one or more options to exercise renewal terms, generally at the Company’s sole discretion, that can extend the lease term. Certain leases contain rights to terminate whereby those termination options are held by either the Company, the lessor, or both parties. These options to extend or terminate a lease are included in the lease term only when it is reasonably certain that the Company will exercise that option. The Company’s leases generally do not contain any material restrictive covenants.
Operating lease cost is recognized on a straight-line basis over the lease term. Information regarding the Company’s leases are as follows:

12. Debt and Other Borrowings
On September 30, 2020, the Company 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 $325,000 senior secured term loan facility due in 2027 (the “Term Loan Facility”). On September 30, 2020, the Company 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 $50,000 senior secured revolving credit facility expiring in 2023 (the “Revolving Credit Facility” and, together with the Term Loan Facility, the “Senior Secured Credit Facilities”). The Revolving Credit Facility is secured by a lien on the same collateral and on the same basis as the Term Loan Facility. Interest on the Term Loan Facility is calculated at LIBOR plus 3.75% to 4.00% based on the Company’s net leverage ratio, and LIBOR is subject to a 0.5% floor. The Company’s outstanding borrowings bore an interest rate of 4.25% at June 25, 2021. As of both June 25, 2021 and March 26, 2021, the Company had $25,000 outstanding under the Term Loan Facility and had not borrowed on the Revolving Credit Facility.
Included in the Term Loan Facility were deferred financing costs of $9,374, which the Company has deducted from the carrying amount presented on its unaudited consolidated balance sheet and amortized into interest expense or recognized as loss on debt extinguishment. Included in the Revolving Credit Facility were deferred financing costs of $300, which the Company classified the related short-term and long-term portions within “Prepaid expenses and other current assets” and “Other assets” on its unaudited consolidated balance sheet and is amortizing those costs over the term of the facility. The unamortized portion of the deferred financing costs associated with the Revolving Credit Facility was $224 at June 25, 2021.
On November 26, 2019, the Company, through its subsidiaries, entered into a line of credit agreement with a financial institution that provides for a maximum borrowing capacity of 60,000 Philippine pesos (approximately $1,230 at June 25, 2021) at the bank’s prevailing interest rate. The line of credit is due to expire on August 31, 2021. There were no borrowings outstanding under this line of credit as of June 25, 2021 and March 26, 2021.
On November 20, 2019, the Company, through its subsidiaries, entered into a line of credit agreement with a financial institution that provides for a maximum capacity of 75,000 Philippine pesos (approximately $1,537 at June 25, 2021) at the bank’s prevailing interest rate. There were no borrowings outstanding under this line of credit as of June 25, 2021 and March 26, 2021. The line of credit expired on June 30, 2021, subsequent to that date, due to delays as a result of the current pandemic situation and its impact with the bank operations. The bank notified the Company of an extension up to September 28, 2021 for all paperwork to be processed.

Total | $ | 19,244 |  |  | $ | 19,133 |

14. Retirement Plans
The Company recognizes the funded status (i.e., the difference between the fair value of plan assets and the benefit obligations) of its defined benefit pension plans in its unaudited consolidated balance sheets with a corresponding adjustment to accumulated other comprehensive income, net of tax. These amounts will continue to be recognized as a component of future net periodic benefit costs consistent with the Company’s past practice. Further, actuarial gains and losses and prior service costs that arise in future periods and are not recognized as net periodic benefit costs in the same periods will be recognized as a component of other comprehensive income. Those amounts will also be recognized as a component of future net periodic benefit costs consistent with the Company’s past practice. The Company uses a measurement date for its defined benefit pension plans and other postretirement benefit plans that is equivalent to its fiscal year-end.

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.
During the three months ended June 25, 2021 and June 26, 2020, the Company contributed approximately $353 and $240 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 Plans
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 2021 and 2020, respectively. The total values of the Pension Promise in the amounts of 703 an d 928 British Pounds Sterling at June 25, 2021 and March 26, 2021, respectively (approximate ly $1,107 and $1,272 at June 25, 2021 and March 26, 2021, 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
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.
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 approximatel y $1,256 and $1,029 for the three months ended June 25, 2021 and June 26, 2020, 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 $218 and $179 for the three months ended June 25, 2021 and June 26, 2020, respectively.
15. Commitments and Contingencies
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
20

Notes to Unaudited Condensed Consolidated Financial Statements – (continued)
(Amounts in thousands, except share and per share amounts)
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. The accrued liability related to self-insurance wa s $1,585 and $1,518 as of June 25, 2021 and March 26, 2021, respectively, and was included in accrued expenses and other current liabilities in the Company’s unaudited consolidated balance sheets.
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 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 the 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 June 25, 2021 or March 26, 2021.
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 June 25, 2021 or March 26, 2021.
16. Net 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 months ended June 26, 2020, 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 months ended June 26, 2020.
The following table sets forth the basic and diluted net 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.

Effective tax rate | 13.3 | % |  | 9.8 | % |  |  |  |

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 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”).
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.
Income tax expense and the effective income tax rate were $4,263, or 13.3%, and $528, or 9.8%, for the three-month periods ending June 25, 2021 and June 26, 2020, respectively. The fluctuation in our effective income tax rate relates primarily to differences in our US taxable income, estimated FDII benefits, research credits, non-deductible stock-based compensation charges, and discrete tax items.

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 the automotive industry. 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 contine nts. Our portfolio includes more than 1,000 products, and we ship over one billion units annually to more than 10,000 customers worldwide. Du ring the three months ended June 25, 2021 and June 26, 2020, we generated $188.1 million and $115.0 million in total net sales, respectively, with $27.7 million and $4.9 million in net income and $53.8 million and $26.2 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 electrified vehicles (“xEVs”), advanced driver 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.
26

•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 sales prices (“ASP”) 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 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. (“Voxtel”), 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 “Voxtel Acquisition”). I n 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.
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 completed the transition and closed our manufacturing facility in Thailand (the “AMTC Facility”) in March 2021. As a result, we expect to realize a significant reduction in cost of goods sold in subsequent periods.
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 introduction and acceptance of our customers’ 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
28

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.
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.
We sell magnetic sensor ICs, power ICs and photonics in the Americas, EMEA and Asia. Revenue is generally recognized when control of the products is transferred to the customer, which typically occurs at a point in time 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.
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.
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 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
29

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.
Change in fair value of contingent consideration
The change in fair value of contingent consideration represents the loss recorded in the three months ended June 25, 2021 resulting from the adjustment in contingent consideration related to the Voxtel Acquisition.
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.
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 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 income tax rate fluctuates primarily because of: the change in the mix of our U.S. and foreign income; the impact of discrete transactions and law changes; and the difference between the amount of tax benefits generated by the foreign derived intangible income deduction (“FDII”) and research credits offset by the additional tax costs associated with global intangible low-tax income (“GILTI”).
30

We regularly assess 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 our results of operations.

Total net sales
Total net sales increased by $73.1 million, or 63.6%, to $188.1 million in the three-month period ended June 25, 2021 from $115.0 million in the three-month period ended June 26, 2020. This increase was primarily due to the continued economic recovery and increase in demand for advanced driver assistance systems, as well as higher demand for data center and industrial automation applications. Gaming and other consumer applications also contributed to the increase in total net sales.
Sales Trends by Market
The following table summarizes total net sales by market. 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.

| Three-Month Period Ended |  | Change
| June 25, 2021 |  | June 26, 2020 |  | Amount |  | %
| (Dollars in thousands)
Automotive | $ | 133,523 |  |  | $ | 76,378 |  |  | $ | 57,145 |  |  | 74.8 | %
Industrial | 30,309 |  |  | 20,406 |  |  | 9,903 |  |  | 48.5 | %
Other | 24,310 |  |  | 18,217 |  |  | 6,093 |  |  | 33.4 | %
Total net sales | $ | 188,142 |  |  | $ | 115,001 |  |  | $ | 73,141 |  |  | 63.6 | %

The increase in net sales by market was driven by increases in automotive of $57.1 million, or 74.8%, industrial of $9.9 million, or 48.5%, and other of $6.1 million, or 33.4%.
32

Automotive net sales increased in the three-month period ended June 25, 2021 compared to the three-month period ended June 26, 2020 primarily due to our customers’ increased vehicle production across most markets due to the on-going recovery from the COVID-19 pandemic. Content in xEV continued to increase year-over-year, and we experienced strong recoveries in ADAS, comfort and convenience and internal combustion engine (“ICE”) applications during the first quarter of 2022.
Industrial and other net sales improved in the three-month period ended June 25, 2021 compared to the three-month period ended June 26, 2020 due primarily to the continued demand in data center applications, gaming, grid infrastructure that includes renewable energy and EV charging, as well as a COVID-related increase in demand for printers and other peripherals.
Sales Trends by Product
The following table summarizes net sales by product:

| Three-Month Period Ended |  | Change
| June 25, 2021 |  | June 26, 2020 |  | Amount |  | %
| (Dollars in thousands)
Power integrated circuits | $ | 66,672 |  |  | $ | 41,599 |  |  | $ | 25,073 |  |  | 60.3 | %

Total net sales | $ | 188,142 |  |  | $ | 115,001 |  |  | $ | 73,141 |  |  | 63.6 | %

Net sales increased across all geographic locations in the three-month period ended June 25, 2021 compared to the three-month period ended June 26, 2020 primarily due to content and market share gains as many countries continue to experience economic expansion coming out of the COVID-19 pandemic and demand for many of our products and applications rose.
The increase in net sales of $16.9 million, or 94.7%, in Europe, predominantly comprised of Germany and France, was primarily driven by increases in automotive demand. The increase in net sales in the United States of $13.8 million, or 106.5%, was primarily driven by the COVID-19 recovery, as well as content and market share gains in ADAS, xEV, ICE,
33

comfort and convenience and industrial applications. Net sales in Japan grew $11.8 million, or 50.1%, which was primarily driven by higher demand for our industrial, xEV and ADAS offerings. The increase in net sales of $10.7 million, or 33.4%, in Greater China related to higher automotive demand, primarily in our ADAS, safety and comfort and convenience sectors. South Korea and Other Asia experienced sales growth of $8.3 million and $7.1 million, respectively, mainly due to higher automotive demand and other customer and peripherals, respectively.
Cost of goods sold, gross profit and gross margin
Cost of goods sold increased by $34.7 million, or 58.5%, to $94.0 million in the three-month period ended June 25, 2021 from $59.3 million in the three-month period ended June 26, 2020. The increase in cost of goods sold was primarily attributable to higher production volume and increases in amortization of manufacturing cost absorptions and excess inventory reserves, specifically expenses of $2.8 million related to the discontinuation of a legacy Voxtel product line during the first quarter of 2022.
Gross profit increased by $38.5 million, or 69.0%, to $94.2 million in the three-month period ended June 25, 2021 from $55.7 million in the three-month period ended June 26, 2020. The increase in gross profit was driven by a $73.1 million operational increase in net sales to all markets discussed above, partially offset by the impacts to cost of goods sold discussed above.
R&D expenses
R&D expenses increased by $5.2 million, or 21.2%, to $29.6 million in the three-month period ended June 25, 2021 from $24.4 million in the three-month period ended June 26, 2020. This increase was primarily due to a combined $4.4 million increase in personnel costs and general operating expenses, including inventory and supplies, and higher stock-based compensation expense of $0.2 million.
R&D expenses represented 15.7% of our total net sales for the three-month period ended June 25, 2021, a decrease from 21.1% of our total net sales for the three-month period ended June 26, 2020. This percentage decrease was primarily due to the growth in net sales in the three-month period ended June 25, 2021.
SG&A expenses
SG&A expenses increased by $5.3 million, or 19.7%, to $32.1 million in the three-month period ended June 25, 2021 from $26.8 million in the three-month period ended June 26, 2020. This increase was primarily due to increases of $3.2 million in each of stock-based compensation expense and contract labor and higher personnel costs of $2.5 million. These higher costs were partially offset by lower facilities costs and professional fees of $2.3 million and $2.1 million, respectively.
SG&A expenses represented 17.0% of our total net sales for the three-month period ended June 25, 2021, a decrease from 23.3% of our total net sales for the three-month period ended June 26, 2020. This percentage decrease was primarily due to the growth in net sales in the three-month period ended June 25, 2021.
Interest (expense) income, net
Interest expense, net was $0.3 million in the three-month period ended June 25, 2021 compared to interest income, net of $0.3 million in the three-month period ended June 26, 2020. The increase in interest expense was primarily due to mandatory interest payments on the Term Loan Facility in the first quarter of 2022 compared to higher interest income received from related parties during the same period last year.
Foreign currency transaction (loss) gain
We recorded a foreign currency transaction loss of $0.3 million in the three-month period ended June 25, 2021 compared to a gain of $0.1 million in the three-month period ended June 26, 2020. The foreign currency transaction loss recorded in the three-month period ended June 25, 2021 was primarily due to the realized and unrealized losses from our UK location in excess of $0.2 million. The foreign currency transaction gain recorded in the three-month period ended June 26, 2020 was primarily due to $1.5 million of realized and unrealized gains from our Thailand location, offset in part by $1.1 million and $0.1 million of realized and unrealized losses from our UK and Philippines locations, respectively.
34

Income in earnings of equity investment
Income in earnings of equity investment reflected a $0.3 million gain in the three-month period ended June 25, 2021, representing the earnings on our 30% investment in PSL.
Other, net
Other, net decreased by $0.2 million to less than $0.1 million of miscellaneous gains in the three-month period ended June 25, 2021 from $0.2 million of miscellaneous gains in the three-month period ended June 26, 2020.
Income tax provision
Income tax expense and the effective income tax rate were $4.3 million, or 13.3%, and $0.5 million, or 9.8%, respectively, in the three-month period ended June 25, 2021 and June 26, 2020, respectively. The fluctuation in our effective income tax rate relates primarily to differences in our U.S. taxable income, estimated FDII benefits, research credits, non-deductible stock-based compensation charges, and discrete tax items.
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, the “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 non-cash 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, our ability to generate cash to service our debt and fund our 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. In particular, management finds it useful to exclude non-cash charges in order to better correlate our operating activities with our ability to generate cash from operations and to exclude certain cash charges as a means of more accurately predicting our liquidity requirements. 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;
35

•although depreciation and amortization are non-cash charges, 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.
The 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, and we calculate non-GAAP Gross Margin as non-GAAP Gross Profit divided by total net sales.
•Voxtel inventory impairment—Represents costs related to the discontinuation of one of our product lines manufactured by Voxtel.
•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 disposition of PSL during the fiscal year ended March 26, 2021 (the “PSL Divestiture”).
•Stock-based compensation—Represents non-cash expenses arising from the grant of stock-based 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 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 was substantially completed in 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 non-cash expenses associated with the amortization of intangible assets in connection with the acquisition of Voxtel, 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 do not include adjustments consisting of:
•Additional AMTC-related costs—Represents costs relating 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 movement of work to the AMPI Facility, which facility had duplicative capacity based on the buildouts of the AMPI Facility in fiscal year s 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 was substantially completed in March 2021.
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.
36

•Transaction fees—Represents transaction-related legal and consulting fees incurred primarily in connection with (i) the acquisition of Voxtel in fiscal year 2020, and (ii) one-time transaction-related legal and consulting fees in fiscal 2021.
•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, (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, and (iii) costs related to the discontinuation of one of our product lines manufactured by Voxtel in fiscal year 2022.
•Impairment of long-lived assets—Represents impairment charge incurred in connection with the planned sale of the AMTC Facility.
•Change in fair value of contingent consideration—Represents the change in fair value of contingent consideration payable in connection with the acquisition of Voxtel.
(**) Non-GAAP Operating Income does not include adjustments consisting of those set forth in note (*) to the calculation of non-GAAP Gross Profit, and the corresponding calculation of non-GAAP Gross Margin, above or:
•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.
EBITDA, Adjusted EBITDA, and Adjusted EBITDA Margin
We calculate EBITDA as net income minus interest income (expense), tax provision (benefit), 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 loss (gain) on sale of equipment—Represents non-core miscellaneous losses and gains on the sale of equipment.
•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.
Non-GAAP Profit before Tax, Non-GAAP Net Income, and Non-GAAP Basic and Diluted Earnings Per Share
We calculate non-GAAP Profit before Tax as Income before Tax Provision excluding the same items excluded above and also excluding the item below in applicable periods. We calculate non-GAAP Net Income as Net Income excluding the same items excluded above and also excluding the item below in applicable periods.
Non-GAAP Provision for Income Tax
In calculating non-GAAP Provision for Income Tax, we have added back the following to GAAP Income Tax Provision:
•Tax effect of adjustments to GAAP results—Represents the estimated income tax effect of the adjustments to non-GAAP Profit Before Tax described above and elimination of discrete tax adjustments.

Liquidity and Capital Resources
As of June 25, 2021, we had $221.9 million of cash and cash equivalents and $333.5 million of working capital compared to $197.2 million of cash and cash equivalents and $313.9 million of working capital as of March 26, 2021. 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 equivalen ts. Our current capital deployment strategy for 2022 is to utilize excess cash on hand to support our growth initiatives into select markets and planned capital expenditures. As of June 25, 2021, the Company is not party to any off-balance sheet arrangements that have 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. The cash requirements for the upcoming fiscal year relate to our leases, operating and capital purchase

commitments and expected contributions to our defined benefit and contribution plans. For information regarding the Company’s expected cash requirements and timing of payments related to debt and borrowing capacity, leases and noncancellable purchase commitments and pension and defined contribution plans, see Note 15, “Commitments and Contingencies”, Note 12, “Debt and Other Borrowings” and Note 14, “Retirement Plans” to the Company’s 2021 Annual Report.
We have experienced and expect to continue to experience—to a smaller degree—increases 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 twelve months. In order to support and achieve our future growth plans, we may need or seek advantageously to obtain additional funding through equity or debt financing. We believe that our current operating structure will facilitate sufficient cash flows from operations to satisfy our expected long-term liquidity requirements beyond the next twelve months. If these resources are not sufficient to satisfy our liquidity requirements due to changes in circumstances, 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.

Net increase in cash and cash equivalents and restricted cash | $ | 25,757 |  |  | $ | 88 |

Operating Activities
Net cash provided by operating activities was $38.5 million in the three months ended June 25, 2021, resulting primarily from our net income of $27.7 million and noncash charges of $17.5 million, partially offset by a net decrease in operating assets and liabilities of $6.7 million. Net changes in operating assets and liabilities consisted of a $10.0 million increase in trade accounts receivable, net and a $2.4 million decrease in accrued expenses and other current and long-term liabilities and a $3.0 million decrease in trade accounts payable, partially offset by a $5.1 million decrease in inventories, a $1.7 million decrease in prepaid expenses, and a $1.9 million increase in net amounts due from related parties. T he increase in trade accounts receivable, net was primarily a result of increased sales year-over-year, as well as the timing of receipts from customers. The decrease in accrued expenses and other current and long-term liabilities was primarily the result of management incentive payments, partially offset by higher accrued personnel costs. Accounts payable decrease d mainly due to the timing of payments to suppliers and vendors, partially offset by higher operating purchases, including unpaid capital expenditures of $5.5 million. The decrease in inventories was primarily a result of the continued drawdown after building inventory up in prior periods to support anticipated sales growth and recovery from the COVID-19 pandemic. The decrease in prepaid expenses and other assets were primarily due to the timing of tax payments, including value-added taxes receivable, insurance and contract costs. The increase in net amounts due to related parties was primarily due to variations in the timing of such payments in the ordinary course of business.
Net cash provided by operating activities was $25.7 million in three-month period ended June 26, 2020, resulting primarily from our net income of $4.9 million and non-cash charges of $11.2 million, partially offset by net changes in operating assets and liabilities of $9.6 million. Net changes in operating assets and liabilities consisted of a decrease of $3.6 million in due from/to related parties, a $4.8 million increase in trade accounts payable, a $13.4 million decrease in trade accounts receivable, net, a $5.2 million decrease in prepaid expenses and other assets, partially offset by a $15.0 million increase in inventories, a $1.6 million decrease in accrued expenses and other current and long-term liabilities, and a $0.7
45

million increase in accounts receivable – other. The decrease in prepaid expenses and other assets was primarily due to the impact of the non-cash removal of PSL-related assets of $5.2 million and a decrease of short-term prepaid arrangements of $2.0 million, partially offset by an increase of deferred IPO costs of $0.4 million and an increase of $0.9 million in other assets due to long-term prepaid contracts. Trade accounts payable were impacted by the non-cash 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 $15.0 million inventory increase is the result of the $18.8 million reduction in balances from March 27, 2020, adjusted for a $32.2 million impact of the non-cash removal of PSL and Sanken distribution business related assets and $1.6 million of non-cash inventory provisions. The decrease in accrued expenses and other current and long-term liabilities is primarily due to the impact of the non-cash removal of PSL-related liabilities of $7.6 million, partially offset by non-cash $6.0 million of deferred taxes. Trade accounts receivable, net, accounts receivable – other, due from/to related parties was primarily due to variations in the timing of such payments in the ordinary course of business.
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, will result in a decrease in capital expenditures in the future.
Net cash used in investing activities was $15.3 million in the three months ended June 25, 2021, consisting of purchases of property, plant and equipment.
Net cash used in investing activities was $24.3 million in the three months ended June 26, 2020, consisting of $8.0 million of purchases of property, plant and equipment and $16.3 million of cash removed as a result of the PSL Divestiture. The $8.0 million change is the result of a change in property, plant and equipment, net of $113.2 million, the impact of the non-cash removal of PSL-related assets of $115.3 million, depreciation of $10.8 million and non-cash purchases in accounts payable of $0.3 million, partially offset by foreign exchange impact of $5.2 million.
Financing Activities
Net cash provided by financing activities was $— in each of the three months ended June 25, 2021 and June 26, 2020.
Debt Obligations
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 due in 2027 (the “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 expiring in 2023 (the “Revolving Credit Facility” and, together with the Term Loan Facility, the “Senior Secured Credit Facilities”).

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 (as defined in the credit agreement) plus an applicable margin from 2.75% to 3.00% depending on our net leverage ratio, or (ii) the Eurodollar Rate (as defined in the credit agreement) 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 June 25, 2021, all term loan borrowings were designated as Eurodollar loans and bore interest of 4.25%.
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 March 26, 2021.
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;
46

•create, incur, or assume indebtedness;

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 (as defined in the credit agreement) 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 $0.2 million at June 25, 2021.
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.
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 expired on June 30, 2021, subsequent to that date, due to delays as a result of the current pandemic situation and its impact with the bank operations. The bank notified the Company of an extension up to September 28, 2021 for all paperwork to be processed.
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.
Critical Accounting Policies and Estimates
47

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Our significant accounting policies are described in Note 2, “Summary of Significant Accounting Policies” to our consolidated financial statements included in our 2021 Annual Report. There have been no material changes in our critical accounting policies and estimates since March 26, 2021.
Item 3. Quantitative and Qualitative Disclosures About Market Risk.
There have been no material changes in our exposures to market risk since March 26, 2021. For details on the Company’s interest rate, foreign currency exchange, and inflation risks, see “Item 7A. Quantitative and Qualitative Information About Market Risks” in our 2021 Annual Report.
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 defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of June 25, 2021. Based on the evaluation of our disclosure controls and procedures as of June 25, 2021, 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.
