We agree to deliver promptly, upon written or oral request, a separate copy of the proxy materials, as requested, to any stockholder at the shared address to which a single copy of those documents was delivered. If you prefer to receive separate copies of the proxy materials, contact our transfer agent at (800) 736-3001 or write them at Computershare, P.O. Box 505000, Louisville, KY 40233-5000.

It is how we create real, long-term value for our ecosystem of employees, customers, supply chain partners, and stockholders.

Globally, women represent 21% of our employees in engineering/technical roles, and 36% of our engineering/technical management roles. Over the past 12 months, 35% of our hires were early career. We also expanded our diversity in leadership last year, adding women to both our executive team and our Board. We continue to make efforts to recruit global new talent from a diverse slate of candidates across all functions and levels of the organization. The diversity of our people, together with their unique ideas and perspectives, enables us to work together toward Allegro’s vision and mission.

Three of our core values: global collaboration, innovate with purpose, and empower with trust, are key to creating a culture where everyone’s ideas are valued. We are working to develop a more holistic diversity, equity, and inclusion (DEI) strategy including the upcoming launch of a DEI Council, affinity groups, an increased focus on diversity recruiting, and targeted training efforts.

Additionally:


•We invest in the ongoing development of our employees and provide education assistance to help mitigate the costs of certification and degree programs, as well as assistance toward the repayment of student debt, an attractive and innovative benefit. •We curate a centralized and broadly used learning management system that houses our training courses, certifications, and compliance modules. •Our talent management system and processes support career development and succession planning.						By the Numbers:
						We’ve paid over $100K in tuition costs for employees in the last 12 months
						Since our student debt assistance program debuted in 2018, we’ve paid more than $315K toward employees’ student debt, saving employees over $375K in principal and interest.
						In the last 12 months, >89% of our employees participated in our robust and ever-expanding learning management system, completing more than 16,000 hours of training collectively.

We also offer peer-to-peer recognition programs, like our High-Five award program, where employees can recognize each other’s achievements and contributions.						By the Numbers:

						Our Dollars for Doers program has matched employee volunteer time with more than $17K in donations
						73% of our employees participated in our most recent employee work-life survey, with 84% reporting that they feel fulfilled in their jobs.

Community Impact

We strive to have a positive impact in our communities and encourage community engagement by our employees. We are proud to support our employees’ causes and match contributions by our employees. We also know that our Company, business goals and our communities are best served when our employees are drawn from a diversity of backgrounds. As such, we are highly focused on increasing our efforts to recruit new members of our highly talented team from underrepresented communities. Some of our community-focused programs include:

•A generous matching gift program for employee donations to qualified nonprofit organizations;

•A volunteer-matching program, “Dollars for Doers” that matches employees’ volunteer hours with in-kind monetary donations to qualified nonprofit organizations;

•Company volunteer days and community service projects, including community clean-ups and supporting local veteran assistance programs;

•Our corporate charitable giving, targeted at STEM education programs and community related programs, such as FIRST Robotics, Grace Hopper, and the Red Cross; and

•Being there when it counts. We uncap our charitable donation matching policies for disaster relief donations globally, most recently in the Philippines for typhoon relief. We also were proud to donate vital PPE to hospitals and first responders around the world during the COVID-19 pandemic.

Our management and Board are committed to furthering our Corporate Social Responsibility and ESG programs and are highly engaged in the work to maintain alignment of our long-term strategy and operations with these core values and goals. We intend to continually monitor our activities and achievements in these areas and report on them on our Corporate Responsibility webpage located at allegromicro.com/en/about-allegro/corporate-responsibility.

In addition, the vote of any stockholder is not disclosed except as may be necessary to meet legal requirements.

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote in accordance with the recommendations of the Board. See “Recommendations of the Board” above.

Proposal	Votes required	Effect of Votes Withheld / Abstentions and Broker Non-Votes

Abstentions have no effect on the ratification of the appointment of Grant Thornton LLP.

16. What are broker non-votes and do they count for determining a quorum?

Generally, broker non-votes occur when shares held by a broker in “street name” for a beneficial owner are not voted with respect to a particular proposal because the broker (1) has not received voting instructions from the beneficial owner and (2) lacks discretionary voting power to vote those shares. A broker is entitled to vote shares held for a beneficial owner on routine matters, such as the ratification of the appointment of Grant Thornton LLP as our independent registered public accounting firm, without instructions from the beneficial owner of those shares. On the other hand, absent instructions from the beneficial owner of such shares, a broker is not entitled to vote shares held for a beneficial owner on non-routine matters, such as the election of directors. Broker non-votes count for purposes of determining whether a quorum is present.

17. Where can I find the voting results of the Annual Meeting?

We plan to announce preliminary voting results at the Annual Meeting, and we will report the final results in a Current Report on Form 8-K, which we intend to file with the SEC after the Annual Meeting.

PROPOSAL ONE: ELECTION OF DIRECTORS

PROPOSALS TO BE VOTED ON

Proposal 1: Election of Directors

We currently have eleven directors on our Board. At the Annual Meeting, four Class I Directors, Noriharu Fujita, Reza Kazerounian, Joseph Martin and Ravi Vig are to be elected to hold office until the 2024 Annual Meeting of Stockholders and until each such director’s respective successor is elected and qualified or until each such director’s earlier death, resignation or removal. Current Class I Director Hideo Takani is not standing for re-election at the Annual Meeting, and the size of the Board will be reduced to ten directors after the Annual Meeting.

The proposal regarding the election of directors requires the approval of a plurality of the votes cast. This means that the nominees receiving the highest number of affirmative “FOR” votes will be elected as Class I Directors. Votes withheld and broker non-votes are not considered to be votes cast and, accordingly, will have no effect on the outcome of the vote on this proposal.

As set forth in our Amended and Restated Certificate of Incorporation, the Board is currently divided into three classes with staggered, three-year terms. At each annual meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following election. The current class structure is as follows: Class I, whose term currently expires at the Annual Meeting and whose subsequent term will expire at the 2024 Annual Meeting of Stockholders; Class II, whose term will expire at the 2022 Annual Meeting of Stockholders; and Class III, whose term will expire at the 2023 Annual Meeting of Stockholders. The current Class I Directors are Noriharu Fujita, Hideo Takani, Reza Kazerounian, Joseph Martin and Ravi Vig; the current Class II Directors are Yoshihiro (Zen) Suzuki, Paul Carl (Chip) Schorr IV and David Aldrich; and the current Class III Directors are Richard Lury, Andrew Dunn and Christine King. In preparation for the initial public offering of our common stock (the “IPO”), we entered into a stockholders’ agreement (the “Stockholders’ Agreement”) with Sanken Electric Co., Ltd. (“Sanken”) and OEP SKNA, L.P. (the “OEP Investor”), a fund affiliated with One Equity Partners (“OEP”). Pursuant to the rights provided in the Stockholders’ Agreement, Messrs. Suzuki, Fujita, Lury and Takani were each designated by Sanken as a Class II, Class I, Class III and Class I Director, respectively (and each as a Sanken Director, as defined below), and Messrs. Dunn, Schorr and Kazerounian were each designated by the OEP Investor as a Class III, Class II and Class I Director, respectively (and each as an OEP Director, as defined below). On June 30, 2021, the Company, Sanken and OEP entered into an addendum to the Stockholders’ Agreement (the “Addendum”). The Addendum allows for the Board size to be ten directors after the Annual Meeting and for Dr. Kazerounian to be nominated for election as a Class I Director as a joint designee of both Sanken and OEP. As a result of the Stockholders’ Agreement (as modified by the Addendum) and the aggregate voting power of the parties to the agreement, we expect that Sanken and the OEP Investor, acting in conjunction, will control the election of directors to the Board. For more information, see “Corporate Governance—Stockholders’ Agreement.”

The division of our Board into three classes with staggered three-year terms may delay or prevent a change of our management or a change in control of our Company. Our directors may be removed only for cause by the affirmative vote of the holders of at least two-thirds of the voting power of all of the then outstanding shares of voting stock of the Company entitled to vote at an election of directors; provided, however, that the directors who were originally designated for nomination in accordance with the Stockholders’ Agreement may be removed with or without cause, but only in accordance with, and to the extent provided by, the terms of the Stockholders’ Agreement.

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote the shares of common stock represented thereby for the election of each of Messrs. Fujita, Kazerounian, Martin and Vig as a Class I Director. In the event that any of Messrs. Fujita, Kazerounian, Martin or Vig should become unable to serve, or for good cause will not serve, as a director, it is intended that votes will be cast for a substitute nominee designated by the Board, or the Board may elect to reduce its size. The Board has no reason to believe that any of Messrs. Fujita, Kazerounian, Martin or Vig will be unable to serve if elected. Each of Messrs. Fujita, Kazerounian, Martin and Vig has consented to being named in this proxy statement and to serve if elected.

PROPOSAL TWO: RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Proposal 2: Ratification of Appointment of Independent Registered Public Accounting Firm

Our Audit Committee has appointed Grant Thornton LLP as our independent registered public accounting firm for the fiscal year ending March 25, 2022. Our Board has directed that this appointment be submitted to our stockholders for ratification at the Annual Meeting. Although ratification of our appointment of Grant Thornton LLP is not required, we value the opinions of our stockholders and believe that stockholder ratification of our appointment is a good corporate governance practice.

Grant Thornton LLP also served as our independent registered public accounting firm for the fiscal year ended March 26, 2021. Neither the accounting firm nor any of its members has any direct or indirect financial interest in or any connection with us in any capacity other than as our auditors, providing audit and non-audit related services. A representative of Grant Thornton LLP is expected to attend the 2021 Annual Meeting and to have an opportunity to make a statement and be available to respond to appropriate questions from stockholders.

In the event that the appointment of Grant Thornton LLP is not ratified by the stockholders, the Audit Committee will consider this fact when it appoints the independent registered public accounting firm for the fiscal year ending March 25, 2022. Even if the appointment of Grant Thornton LLP is ratified, the Audit Committee retains the discretion to appoint a different independent registered public accounting firm at any time if it determines that such a change is in the interest of the Company.

Vote Required

This proposal requires the affirmative vote of the holders of a majority in voting power of the votes cast. Abstentions are not considered to be votes cast and, accordingly, will have no effect on the outcome of the vote on this proposal. Because brokers have discretionary authority to vote on the ratification of the appointment of Grant Thornton LLP, we do not expect any broker non-votes in connection with this proposal.

The Board unanimously recommends a vote FOR the Ratification of the Appointment of Grant Thornton LLP as our Independent Registered Public Accounting Firm for the fiscal year ending March 25, 2022.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

The Audit Committee has reviewed the audited consolidated financial statements of the Company for the fiscal year ended March 26, 2021 and has discussed these financial statements with management and the Company’s independent registered public accounting firm. The Audit Committee has also received from, and discussed with, the Company’s independent registered public accounting firm various communications that such independent registered public accounting firm is required to provide to the Audit Committee, including the matters required to be discussed by statement on Auditing Standards No. 1301, as adopted by the Public Company Accounting Oversight Board (“PCAOB”).

The Company’s independent registered public accounting firm also provided the Audit Committee with a formal written statement required by PCAOB Rule 3526 (Communications with Audit Committees Concerning Independence) describing all relationships between the independent registered public accounting firm and the Company, including the disclosures required by the applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence. In addition, the Audit Committee discussed with the independent registered public accounting firm its independence from the Company.

Based on its discussions with management and the independent registered public accounting firm, and its review of the representations and information provided by management and the independent registered public accounting firm, the Audit Committee recommended to the Board of Directors that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 26, 2021.

Audit Committee Pre-Approval Policy and Procedures

The Audit Committee is directly responsible for the appointment, compensation, retention and oversight of the independent registered public accounting firm retained to audit the Company’s financial statements. The Audit Committee is responsible for the audit fee negotiations associated with the Company’s retention of Grant Thornton LLP. The Audit Committee has established a policy regarding pre-approval of all audit and non-audit services provided by the independent registered public accountants.

On an ongoing basis, management communicates specific projects and categories of services for which the advance approval of the Audit Committee is requested. The Audit Committee reviews these requests and advises management if the Audit Committee approves the engagement of the independent registered public accountants. On a periodic basis, management reports to the Audit Committee regarding the actual spending for such projects and services as compared to the approved amounts. The Audit Committee may also delegate the ability to pre-approve audit and permitted non-audit services to a subcommittee consisting of one or more members, provided that such pre-approvals are reported on at a subsequent Audit Committee meeting. All services performed for the fiscal year ended March 26, 2021 were pre-approved by the Audit Committee.

CORPORATE GOVERNANCE

General

Our Board has adopted Corporate Governance Guidelines, a Code of Business Conduct and Ethics, and charters for our Nominating and Corporate Governance Committee, Audit Committee, Compensation Committee and Research & Development and Strategy Committee to assist the Board in the exercise of its responsibilities and to serve as a framework for the effective governance of the Company. You can access our current committee charters, our Corporate Governance Guidelines, and our Code of Business Conduct and Ethics in the “Governance” section under the “Documents & Charters” in our investor relations section of our corporate website located at investors.allegromicro.com, or by writing to our Secretary at our offices at 955 Perimeter Road, Manchester, New Hampshire, 03103.

Board Composition

Our business and affairs are managed under the direction of our Board. Our Board currently consists of eleven members: Ravi Vig, Andrew Dunn, Noriharu Fujita, Reza Kazerounian, Christine King, Richard Lury, Joseph Martin, Paul Carl (Chip) Schorr IV, Yoshihiro (Zen) Suzuki, Hideo Takani and David Aldrich. Mr. Takani is not standing for re-election at the Annual Meeting, and the size of the Board will be reduced to ten directors after the Annual Meeting. Our Board is divided into three classes, with the directors in each class serving for a three-year term, and one class being elected each year by our stockholders.

When considering whether directors have the experience, qualifications, attributes or skills, taken as a whole, to enable our Board to satisfy its oversight responsibilities effectively in light of our business and structure, our Board focuses primarily on each person’s background and experience as reflected in the information discussed in each of the directors’ individual biographies set forth above. We believe that our directors provide an appropriate mix of experience and skills relevant to the size and nature of our business.

Stockholders’ Agreement

In connection with our IPO, we entered into the Stockholders’ Agreement with certain stockholders of the Company, including Sanken and the OEP Investor. Pursuant to the Stockholders’ Agreement, the parties agreed that:

•prior to our first annual meeting of stockholders following the closing of the IPO (the “First Annual Meeting”), our Board will consist of eleven directors, and following the First Annual Meeting, our Board will consist of nine directors; however, on June 30, 2021, the Company, Sanken and OEP entered into the Addendum, which allows for the Board size to be ten directors after the Annual Meeting and for Dr. Kazerounian to be nominated for election as a Class I Director as a joint designee of both Sanken and OEP;

•for as long as Sanken, directly or indirectly, beneficially owns, in the aggregate, at least 5% of our common stock, Sanken will have the right to designate that number of individuals for nomination in any election of directors which, assuming all such individuals are successfully elected as directors, when taken together with any incumbent directors that have been nominated by Sanken not then standing for election, would result in there being (A) prior to the First Annual Meeting, four such directors designated by Sanken on our Board, and (B) from and after the First Annual Meeting, three such directors designated by Sanken on our Board (provided, that any individuals designated by Sanken as described in this clause that are different from the initial individuals designated by Sanken upon the consummation of the IPO shall require the prior written approval of the OEP Investor (not to be unreasonably withheld)) (the individuals described in this clause being “Sanken Directors”);

•for as long as the OEP Investor, directly or indirectly, beneficially owns, in the aggregate, at least 5% of our common stock, the OEP Investor will have the right to designate (i) that number of individuals for nomination in any election of directors which, assuming all such individuals are successfully elected as directors, when taken together with any incumbent directors that have been nominated by the OEP Investor not then standing for election, would result in there being (A) prior to the First Annual Meeting, three such directors designated by the OEP Investor on our Board, and (B) from and after the First Annual Meeting, two such directors designated by the OEP Investor on our Board (provided, that any individuals designated by the OEP Investor as described in this sub-clause (i) that are different from the initial individuals designated by the OEP Investor upon the consummation of the IPO shall require the prior written approval of Sanken (not to be unreasonably withheld)) (the individuals described in this sub-clause (i) being “OEP Directors”), and (ii) that number of individuals who satisfy the independence requirements specified in the Stockholders’ Agreement for nomination in any election of directors, which, assuming all such individuals are successfully elected as

CORPORATE GOVERNANCE

directors, when taken together with any incumbent directors who satisfy such independence requirements that have been nominated by the OEP Investor not then standing for election, would result in there being three such directors that satisfy the independence requirements designated by the OEP Investor on our Board (provided, that any individuals designated by the OEP Investor as described in this sub-clause (ii) that are different from the initial individuals designated by the OEP Investor upon the consummation of the IPO shall require the prior written approval of Sanken (not to be unreasonably withheld)) (the individuals described in this sub-clause (ii) being “Selected Independent Directors”); and

•unless otherwise agreed, our then-current Chief Executive Officer will be designated for nomination by the Board in any applicable election.

Sanken and the OEP Investor generally have the right to remove and replace directors that they have respectively designated, subject to certain consent rights in favor of the other holder. Pursuant to the Stockholders’ Agreement, each of the OEP Investor and Sanken have agreed to take all necessary action (as defined in the Stockholders’ Agreement) to provide that one of the Sanken Directors and one of the OEP Directors who were Class I directors at the time of the closing of the IPO will not stand for re-election at the First Annual Meeting, and that our Board will decrease in size to nine members from and after such meeting; however, on June 30, 2021, the Company, Sanken and OEP entered into the Addendum, which allows for the Board size to be ten directors after the Annual Meeting and for Dr. Kazerounian to be nominated for election as a Class I Director as a joint designee of both Sanken and OEP.

Each of Sanken and the OEP Investor will also agree to vote, or cause to be voted, all of their outstanding shares of our common stock at any annual or special meeting of stockholders in which directors are elected, and to otherwise take all necessary action (as defined in the Stockholders’ Agreement) so as to cause the election or appointment of the designees described above. Additionally, pursuant to the Stockholders’ Agreement, we will agree to take all commercially reasonable actions to cause (1) our Board to be comprised of the number of directors described above; (2) the individuals designated in accordance with the terms of the Stockholders’ Agreement to be included in the slate of nominees to be elected at the next annual or special meeting of our stockholders at which directors are to be elected, and at each annual meeting of our stockholders thereafter at which a director’s term expires; and (3) the individuals designated in accordance with the terms of the Stockholders’ Agreement to fill the applicable vacancies on our Board. The Stockholders’ Agreement allows for our Board to reject the nomination, appointment or election of a particular director if such nomination, appointment or election would constitute a breach of the Board’s fiduciary duties to our stockholders or does not otherwise comply with any requirements of our amended and restated certificate of incorporation or our amended and restated bylaws.

In addition, the Stockholders’ Agreement provides each of Sanken and OEP with a consent right (subject to certain ownership minimums) over our entry into any transaction with Sanken, the OEP Investor, any of their respective affiliates or any of our affiliates. The Stockholders’ Agreement also includes a covenant between Sanken and the OEP Investor that gives the OEP Investor the right to require Sanken to vote all of its shares in favor of any matter that our Board has determined is advisable and in the best interests of the stockholders and has recommended that the stockholders adopt. The Stockholders’ Agreement further provides that neither Sanken nor the OEP Investor will directly sell a portion of its common stock representing greater than 10% of our outstanding shares of common stock to a material competitor of the Company or of the other stockholder in a privately negotiated sale solely between such selling stockholder and such competitor, without the prior written consent of the OEP Investor (in the case of a sale by Sanken) or Sanken (in the case of a sale by the OEP Investor).

The Stockholders’ Agreement will terminate upon the earlier to occur of (a) each of (i) Sanken and its affiliates and (ii) the OEP Investor and its affiliates ceasing to own any shares of our common stock, and (b) the unanimous written consent of the parties thereto. In addition, the rights and obligations of Sanken and the OEP Investor under the Stockholders’ Agreement will terminate upon Sanken and its affiliates (in the case of Sanken) or the OEP Investor and its affiliates (in the case of the OEP Investor) ceasing to own any shares of our common stock.

Director Independence

Our common stock is listed on the Nasdaq Global Select Market. Under the Nasdaq rules, a director will only qualify as an “independent director” if that company’s board of directors affirmatively determines that such person does not have a relationship with the company that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Our Board undertook a review of the independence of our directors and considered whether any director has a material relationship with us that could compromise that director’s ability to exercise independent judgment in carrying out that


			INNOVATION WITH PURPOSE			29

CORPORATE GOVERNANCE

director’s responsibilities. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our Board has determined that none of David Aldrich, Andrew Dunn, Noriharu Fujita, Christine King, Richard Lury, Joseph Martin, and Paul Carl (Chip) Schorr IV, representing seven of our eleven directors, has a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is “independent” as that term is defined under the Nasdaq rules. In making these determinations, our Board considered the current and prior relationships that each director has with our Company and all other facts and circumstances our Board deemed relevant in determining their independence, including their beneficial ownership of our capital stock and relationships with certain of our significant stockholders, and the transactions involving them described in the section titled “Certain Relationships and Related Person Transactions.”

Director Candidates

Other than director candidates designated by Sanken and the OEP Investor pursuant to the Stockholders’ Agreement, the Nominating and Corporate Governance Committee of the Board is primarily responsible for searching for qualified director candidates for election to the Board and filling vacancies on the Board. To facilitate the search process, the Nominating and Corporate Governance Committee may solicit current directors and executives of the Company for the names of potentially qualified candidates. The Nominating and Corporate Governance Committee may also consult with outside advisors or retain search firms to assist in the search for qualified candidates, or consider director candidates recommended by our stockholders. Once potential candidates are identified, the Nominating and Corporate Governance Committee reviews the backgrounds of those candidates, evaluates candidates’ independence from the Company and potential conflicts of interest and determines if candidates meet the qualifications desired by the Nominating and Corporate Governance Committee for candidates for election as a director.

In evaluating the suitability of individual candidates (both new candidates and current Board members), the Nominating and Corporate Governance Committee, in recommending candidates for election, and the Board, in approving (and, in the case of vacancies, appointing) such candidates, may take into account many factors, including: personal and professional integrity, ethics and values; experience in corporate management, such as serving as an officer or former officer of a publicly held company; strong finance experience; relevant social policy concerns; experience relevant to the Company’s industry; experience as a board member or executive officer of another publicly held company; relevant academic expertise or other proficiency in an area of the Company’s operations; diversity of expertise and experience in substantive matters pertaining to the Company’s business relative to other Board members; diversity of background and perspective, including, but not limited to, with respect to age, gender, race, place of residence and specialized experience; practical and mature business judgment, including, but not limited to, the ability to make independent analytical inquiries; and any other relevant qualifications, attributes or skills. The Board evaluates each individual in the context of the Board as a whole, with the objective of assembling a group that can best perpetuate the success of the business and represent stockholder interests through the exercise of sound judgment using its diversity of experience in these various areas. In determining whether to recommend a director for re-election, the Nominating and Corporate Governance Committee may also consider the director’s past attendance at meetings and participation in and contributions to the activities of the Board.

Stockholders may recommend individuals to the Nominating and Corporate Governance Committee for consideration as potential director candidates by submitting the names of the recommended individuals, together with appropriate biographical information and background materials, to the Nominating and Corporate Governance Committee, c/o Secretary, Allegro MicroSystems, Inc., 955 Perimeter Road, Manchester, New Hampshire, 03103. In the event there is a vacancy, and assuming that appropriate biographical and background material has been provided on a timely basis, the Nominating and Corporate Governance Committee will evaluate stockholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates submitted by others.

Communications from Stockholders

The Board will give appropriate attention to written communications that are submitted by stockholders, and will respond if and as appropriate. Our Secretary is primarily responsible for monitoring communications from stockholders and for providing copies or summaries to the directors as he considers appropriate.

Communications are forwarded to all directors if they relate to important substantive matters and include suggestions or comments that our Secretary considers to be important for the directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we tend to receive repetitive or duplicative communications. Stockholders who wish to send communications on any topic to the Board should address such


			INNOVATION WITH PURPOSE			30

CORPORATE GOVERNANCE

communications to the Board of Directors in writing: c/o Secretary, Allegro MicroSystems, Inc. 955 Perimeter Road, Manchester, New Hampshire, 03103.

Board Leadership Structure and Role in Risk Oversight

Our Amended and Restated Bylaws and Corporate Governance Guidelines provide our Board with flexibility to combine or separate the positions of Chairman of the Board and Chief Executive Officer in accordance with its determination that utilizing one or the other structure would be in the best interests of our Company. Currently, the roles are separated, with Yoshihiro Suzuki serving as Chairman of the Board and Ravi Vig serving as President and Chief Executive Officer and as a director. Our Board has determined that separating the roles of Chairman of the Board and Chief Executive Officer allows our Chief Executive Officer to focus on the strategic management of our day-to-day business, while allowing the Chairman to focus on leading the Board in its fundamental role of providing advice to, and independently overseeing, management. The Board recognizes the time, effort, and energy that the Chief Executive Officer is required to devote to the position in the current business environment, as well as the commitment required to serve as our Chairman. The Board believes that having separate positions, with a non-executive director serving as the Chairman, is the appropriate leadership structure for our Company at this time and allows the Board to fulfill its role with appropriate independence. For these reasons and because of the strong leadership of Mr. Suzuki and Mr. Vig, our Board has concluded that our current leadership structure is appropriate at this time.

However, our Board will continue to periodically review our leadership structure and may make such changes in the future as it deems appropriate. Our Corporate Governance Guidelines provide that whenever our Chairman of the Board is also a member of management or is a director that does not otherwise qualify as an independent director, the independent directors may elect a lead director.

Our Board has an active role, as a whole and also at the committee level, in overseeing the management of our risks. Our Board is responsible for overseeing our risk management process. Our Board focuses on our general risk management strategy, the most significant risks facing us, and oversees the implementation of risk mitigation strategies by management. Our Audit Committee is also responsible for discussing our policies with respect to risk assessment and risk management, and is responsible for overseeing the management of risks relating to accounting matters and financial reporting. Our Compensation Committee is responsible for overseeing the management of risks relating to our executive compensation plans and arrangements. Our Nominating and Corporate Governance Committee is responsible for overseeing the management of risks associated with the independence of our Board and potential conflicts of interest. Although each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board is regularly informed through discussions with committee members and regular reports from management about such risks, as well as the actions taken by management to adequately address those risks. Our Board believes its administration of its risk oversight function has not negatively affected our Board’s leadership structure.

Code of Business Conduct and Ethics

Our Board has adopted a written Code of Business Conduct and Ethics that applies to our directors, officers and employees (including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions). A copy of the Code of Business Conduct and Ethics is posted on our investor relations website at investors.allegromicro.com. In addition, we have or intend to post on our website all disclosures that are required by law or the Nasdaq rules concerning any amendments to, or waivers from, any provision of the code. Information contained on, or that can be accessed through, our website is not incorporated by reference in this prospectus and does not form a part of this prospectus. The inclusion of our website address in this prospectus is an inactive textual reference only.

Anti-Hedging Policy

Our Board has adopted an Insider Trading Compliance Policy, which applies to all directors, officers and employees of the Company and its subsidiaries, as well as their respective family members sharing the same household, and any other company, account, trust or other entity that they control (the “Covered Persons”). The policy prohibits Covered Persons from purchasing financial instruments such as prepaid variable forward contracts, equity swaps, collars, and exchange funds, or otherwise engaging in transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of the Company’s equity securities, or that may cause any Covered Person to no longer have the same objectives as the Company’s other stockholders.

CORPORATE GOVERNANCE

Stock Ownership Guidelines

The Company has stock ownership guidelines for directors and officers that require each director and officer to own shares of our common stock. Under the guidelines, all current directors and officers must own shares of our common stock with a value equal to a certain multiple of their annual Board retainer or base salary. Please refer to the table below for the applicable multiple. Equity interests that count towards the satisfaction of the ownership guidelines include vested shares, including shares owned outright, shares jointly owned, shares owned in trust, and shares held in a 401(k) retirement plan. Directors and officers have four years from the date of the Company’s IPO or, if later, the date they become a member of the Board or an officer to meet the ownership levels.


Covered Person			Multiple of Salary / Retainer

Attendance by Members of the Board at Meetings

There were seven meetings of the Board during the fiscal year ended March 26, 2021. During the fiscal year ended March 26, 2021, each director attended at least 75% of the aggregate of (i) all meetings of the Board and (ii) all meetings of the committees on which the director served during the period in which he or she served as a director.

Under our Corporate Governance Guidelines, which are available on our investor relations website at investors.allegromicro.com, a director is expected to spend the time and effort necessary to properly discharge his or her responsibilities. Accordingly, a director is expected to regularly prepare for and attend meetings of the Board and all committees on which the director sits (including separate meetings of the independent directors), with the understanding that, on occasion, a director may be unable to attend a meeting. A director who is unable to attend a meeting of the Board or a committee of the Board is expected to notify the Chairman of the Board or the chair of the appropriate committee in advance of such meeting, and, whenever possible, participate in such meeting via teleconference in the case of an in-person meeting. We do not maintain a formal policy regarding director attendance at the Annual Meeting; however, it is expected that absent compelling circumstances directors will attend.

EXECUTIVE AND DIRECTOR COMPENSATION

Narrative to Summary Compensation Table

Salaries

The named executive officers receive a base salary to compensate them for services rendered to our Company. The base salary payable to each named executive officer is intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, role and responsibilities.

The initial base salaries for Messrs. Vig, Walsh, and Doogue for fiscal year 2021 were $500,000, $372,200, and $350,000, respectively.

During fiscal year 2021, the base salaries of our named executive officers were temporarily reduced as part of a cost savings initiative in response to the COVID-19 pandemic. Effective May 9, 2020, each executive’s salary was reduced by approximately 15% and salaries were restored to their prior levels effective September 26, 2020. No make-whole payments in relation to such salary reductions were paid.

Cash Bonuses

Under our annual incentive plan, we have historically paid certain of our employees, including our named executive officers, annual cash bonuses, based on the attainment of individual and/or Company performance goals for the applicable fiscal year. During fiscal year 2021, Messrs. Vig, Walsh, and Doogue had annual bonus opportunities targeted at 100%, 70%, and 65%, respectively, of their respective base salaries, determined by reference to Company and individual performance. For fiscal year 2021, Company performance metrics were based on EBIT and revenue goals that were set at the beginning of the year and the Compensation Committee’s subjective overall determination of Company and individual performance. For fiscal year 2021, the Compensation Committee determined that EBIT and revenue targets were achieved at 125% of target. The Compensation Committee also determined that bonuses for our named executive officers should be paid at 115% of target for Messrs. Vig and Walsh and at 100% of target for Mr. Doogue. The bonus amounts that were paid to our named executive officers for fiscal year 2021 under our annual incentive plan are shown in the 2021 Summary Compensation Table under the heading “Non-Equity Incentive Plan Compensation.”

Equity Compensation

During fiscal year 2021, we adopted, and our stockholders approved, a 2020 Omnibus Incentive Compensation Plan (the “2020 Plan”) in order to facilitate the grant of cash and equity incentives to directors, employees (including our named executive officers) and consultants of our Company and certain of our affiliates and to enable our Company and certain of our affiliates to obtain and retain services of these individuals, which is essential to our long-term success.

In connection with the consummation of our IPO during fiscal year 2021, Messrs. Vig, Walsh and Doogue received grants of restricted stock units (“RSUs”) and PSUs. The RSUs will vest in substantially equal installments on each of the first four anniversaries of November 18, 2020, subject to the executive’s continued employment through the applicable vesting date, and further subject to accelerated vesting eligibility on certain qualifying terminations of employment or service. The PSUs will vest based on based on the attainment of specified performance goals linked to total shareholder return and specified financial goals over a performance period covering fiscal years 2021 through 2023.

Other Elements of Compensation

Deferred Compensation: We maintain the Executive Deferred Compensation Plan of AML (as amended, the “Deferred Compensation Plan”), under which eligible employees, including our named executive officers, are permitted to defer up to 90% of their base salary and/or up to 100% of any amount earned under a bonus plan. All deferrals are fully vested as of the date on which the deferral is made. During fiscal year 2021, we also made fully-vested employer contributions to our named executive officers’ (and other participants’) Deferred Compensation Plan accounts in an amount sufficient to replace matching


			INNOVATION WITH PURPOSE			37

EXECUTIVE AND DIRECTOR COMPENSATION

contributions that would have been made under our 401(k) retirement savings plan (discussed below) based on total compensation, but were not made under the 401(k) retirement savings plan due to applicable statutory limitations, with such matching contributions capped at 5% the applicable participant’s annual eligible compensation. Amounts deferred under the Deferred Compensation Plan may be notionally invested by participants in one or more notional investment funds or indexes designated by the plan administrator, and are subject to adjustment for earnings (or losses) resulting from such notional investment. Deferred Compensation Plan accounts are generally distributable upon the first to occur of a participant’s termination of employment (subject to a six- month delay if required by applicable regulations), the participant’s death or a change in control of the Company. Participants may also elect certain in- service or other fixed distribution dates and/or installment payments (including with respect to distributions following a termination of employment).

Retirement Plans. We currently maintain a 401(k)-retirement savings plan for our employees, including our named executive officers, who satisfy certain eligibility requirements. Our named executive officers are eligible to participate in the 401(k) plan on the same terms as other full-time employees. The Internal Revenue Code of 1986, as amended (the “Code”) allows eligible employees to defer a portion of their compensation, within prescribed limits, on a pre-tax basis through contributions to the 401(k) plan. Currently, we match contributions made by participants in the 401(k) plan up to a specified percentage of the employee’s eligible compensation, and these matching contributions are fully vested as of the date they are made. We believe that providing a vehicle for tax-deferred retirement savings though our 401(k) plan adds to the overall desirability of our executive compensation package and further incentivizes our employees, including our named executive officers, in accordance with our compensation policies.

Employee Benefits and Perquisites

Health/Welfare Plans: All of our full-time employees, including our named executive officers, are eligible to participate in our health and welfare plans, including:

•medical, dental and vision benefits;

•medical and dependent care flexible spending accounts;

•health savings accounts;

•short-term and long-term disability insurance; and

•life insurance.

Matching Charitable Donations: Subject to certain limitations, we match charitable donations made by our employees, including our named executive officers, to eligible charitable organizations up to annual donations of $5,000 per employee. During fiscal year 2021, we matched $2,108 in charitable donations made by Mr. Walsh and $575 in charitable donations made by Mr. Doogue.

Inventor Awards Program: Under our Inventor Awards Program, our employees (including our named executive officers) are eligible to earn cash incentives associated with U.S. patents, including upon filing invention disclosures, issuances of first, second and third patents associated with such invention disclosures, and in respect of an annual “innovation award” selected from patents issued in respect of invention filings in a given year. Incentives associated with the foregoing patent-related awards range from $100 to $5,000 per occurrence depending on the particular type of award. During fiscal year 2021, we awarded Messrs. Vig and Doogue $1,500 and $4,500, respectively, under the Inventor Awards Program.

We believe the perquisites described above are necessary and appropriate to provide a competitive compensation package to our named executive officers.

Outstanding Equity Awards at Fiscal Year-End

The following table summarizes the number of RSUs outstanding for each named executive officer as of March 26, 2021. None of our named executive officers held option awards as of March 26, 2021.

Executive Compensation Arrangements

Amended and Restated Severance Agreements

We entered into severance agreements with AML and each of our named executive officers (together, the “Severance Agreements”) on October 3, 2017. The Company amended and restated the Severance Agreements, effective as of September 30, 2020. The Severance Agreements (as amended and restated) provide that if a named executive officer’s employment is terminated by the Company without “cause” or by the executive for “good reason” (each such term as defined in the applicable Severance Agreement), subject to the executive’s execution of an effective general release of claims and continued compliance with applicable non-competition, non-solicitation and other restrictive covenants applicable to the executive pursuant to the respective Class L Shares award agreement, we will pay or provide the executive with the following severance benefits:

(i) a percentage of the executive’s annual base salary and target bonus, in each case, as in effect on the date of such termination, equal to 300% (for Mr. Vig), 200% (for Mr. Walsh), and 100% (for Mr. Doogue), payable in cash;

(ii) the executive’s target bonus in effect on the applicable date of termination, prorated for the number of days the executive was employed by the Company during the year of such termination, payable in cash;

(iii) any then-outstanding incentive equity awards (then-held by our named executive officers) will be governed by the applicable equity incentive plan or award agreement; and

(iv) Company-paid continued health care coverage for up to thirty-six months (for Mr. Vig), up to twenty-four months (for Mr. Walsh) and up to eighteen months (for Mr. Doogue) following the date of such termination. During fiscal year 2021, the Severance Agreements also provided that, to the extent such COBRA continuation would result in the imposition of income taxes on the executive, an additional monthly payment would be made to the executive to cover the amount of any such taxes for up to eighteen months following the date of such termination; however, in connection with the IPO, we have removed these provisions from the Severance Agreements (as amended and restated) such that no tax gross-ups have been or will become payable thereunder.

Subject to applicable withholding, the cash severance benefits described in clauses (i) and (ii) above will be paid as follows: (A) for Mr. Vig, two times the lesser of (x) Mr. Vig’s annualized compensation for the year prior to the year in which the termination occurred and (y) the maximum amount that may be taken into account under a qualified plan under Section 401(a) of the Code for the year of termination, will be payable in equal monthly installments during the twelve-month period following the date of such termination in accordance with our normal payroll practices, and the remaining portion of Mr. Vig’s cash severance


			INNOVATION WITH PURPOSE			39

EXECUTIVE AND DIRECTOR COMPENSATION

benefits will be paid in a lump-sum payment within sixty days following the termination and (B) for Messrs. Walsh and Doogue, 100% of the sum of the executive’s annual base salary and target bonus plus the pro-rated target bonus will be paid to the applicable executive in a lump-sum payment within sixty days following the termination, and the remaining portion of the executive’s cash severance benefits will be paid in equal monthly installments during the twelve-month period following the date of such termination, in accordance with our normal payroll practices.

Potential Payments upon Termination or a Change in Control

Our named executive officers would be entitled to severance payments and benefits in the event their employment with us is terminated following an involuntary termination, which would include a termination of the officer’s employment by us without cause or a resignation for good reason, or a Qualifying Termination. For more information, refer to the discussion above under the heading —Executive Severance Arrangements – Amended and Restated Severance Agreements. In addition, upon a Qualifying Termination within 12 months following a change in control of our Company, all outstanding equity incentive awards held by such executive under the 2020 Plan will vest, with performance measured based on the greater of target or actual performance. Upon a Qualifying Termination outside of such 12-month period following a change in control of our Company, such executive’s RSUs which are eligible to vest on the next vesting date following such termination will vest, and a pro-rated portion of such executive’s PSUs would vest as of the date of such termination.

The following table shows potential payments to our named executive officers under the executive severance arrangements and with respect to their outstanding equity incentive awards for various scenarios involving a termination of employment or a change in control, assuming such event occurred on March 26, 2021 and, where applicable, using a price of our common stock of $25.27:

Equity Compensation

•IPO Grants: Each Eligible Director serving on our Board upon the effectiveness of our IPO during fiscal year 2021 was granted an RSU award under the 2020 Plan with a value of approximately $170,000 (each, an “IPO Grant”), which IPO Grant will vest in full on the date of the first annual meeting of our stockholders following the IPO, subject to the director’s continued service through the applicable vesting date (and further subject to accelerated vesting as described below). The number of RSUs subject to each IPO Grant was determined by reference to the initial public offering price per share of our common stock.

•Annual Grant: Each Eligible Director serving on our Board as of the date of the annual meeting of our stockholders (beginning with calendar year 2021) will be granted, on such annual meeting date, an RSU award with a value of approximately $170,000 (each, an “Annual Award”), which will vest in full on the date of the next annual meeting of our stockholders following the grant date, subject to the director’s continued service through the applicable vesting date (and further subject to accelerated vesting as described below). The number of RSUs subject to an Annual Award will be determined by dividing $170,000 by the trailing 30-calendar day average closing price for the Company’s common stock through and including the date prior to the applicable grant date.

•Pro Rata Grants: If any Eligible Director is initially elected or appointed to serve on the Board subsequent to the IPO and on a date other than the date of an annual meeting of our stockholders, such Eligible Director’s will receive an initial RSU award for the period of service through the annual meeting of our stockholders next-following such election or appointment determined based on the number of days elapsed since the last occurring annual meeting of our stockholders, as follows: (i) $170,000 multiplied by (ii) a fraction, (x) the numerator of which equals 365 minus the number of days elapsed since such last occurring annual meeting (but not less than zero) and (y) the denominator of which is equal to 365.

If an Eligible Director ceases to serve on our Board due to the Eligible Director’s death, or disability, or during such Eligible Director’s service on our Board a change in control of our Company occurs (as defined in the 2020 Plan), all incentive equity awards held by such Eligible Director will vest in full upon such event. Compensation under our Director Compensation Program will be subject to the annual limits on non-employee director compensation set forth in the 2020 Plan, as described a.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth certain information with respect to holdings of our common stock by (i) stockholders who beneficially owned more than 5% of the outstanding shares of our common stock, and (ii) each of our directors, each of our named executive officers and all directors and executive officers as a group as of June 11, 2021, unless otherwise indicated.

The number of shares beneficially owned by each stockholder as described in this proxy statement is determined under rules issued by the SEC. Under these rules, beneficial ownership includes any shares as to which the individual or entity has sole or shared voting power or investment power. The percentage ownership of each individual or entity as of June 11, 2021 is computed on the basis of 189,589,991 shares of our common stock outstanding. In computing the number of shares beneficially owned by an individual or entity and the percentage ownership of that person, shares of common stock subject to options, or other rights, held by such person that are currently exercisable or will become exercisable within 60 days of June 11, 2021, are considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person. Unless otherwise indicated, the address of each beneficial owner listed below is 955 Perimeter Road, Manchester, New Hampshire, 03103. We believe, based on information provided to us, that each of the stockholders listed below has sole voting and investment power with respect to the shares beneficially owned by the stockholder unless noted otherwise, subject to community property laws where applicable.

Policies and Procedures for Related Person Transactions

Our Board recognizes that transactions with related persons present a heightened risk of conflicts of interests and/or improper valuation (or the perception thereof). Our Board has adopted a written policy which provides that our Audit Committee will approve or ratify related person transactions required to be disclosed pursuant to Item 404 of Regulation S-K. Item 404 of Regulation S-K requires disclosure, subject to certain exceptions, of transactions in which we were or are to be a participant and the amount involved exceeds $120,000 and in which any “related person” as defined under Item 404(a) of Regulation S-K had or will have a direct or indirect material interest. It is our policy that directors interested in a related person transaction will recuse themselves from any vote on a related person transaction in which they have an interest and that no director may participate in the approval of a related person transaction for which he or she is a “related person.” Each of the transactions described below was entered into prior the adoption of our related person transaction policy.

Related Person Transactions

In addition to the compensation arrangements, including employment, termination of employment and change in control arrangements, discussed in the section titled “Executive and Director Compensation,” the following is a description of each transaction or agreement since March 28, 2020 and each currently proposed transaction in which:

•we have been or are to be a participant;

•the amount involved exceeded or exceeds $120,000; and

•any of our directors, executive officers or, to our knowledge, beneficial owners of more than 5% of our common stock, or any immediate family member of, or person sharing a household with, any of these individuals or entities, had or will have a direct or indirect material interest.

The following descriptions include summaries of certain provisions of our related party agreements and are qualified in their entirety by reference to the full text of any such agreement filed as an exhibit to our Annual Report on Form 10-K.

Related Party Agreements in Effect Prior to our IPO

Common Stock Repurchases

In October 2020, we entered into repurchase agreements with certain of our directors, executive officers and other employees that provided for our repurchase from each such holder of a number of shares of common stock sufficient to generate proceeds to satisfy certain tax obligations triggered by the vesting of the shares of Class A common stock or a portion of the shares of Class L common stock, as applicable, held by such holder that occurred in connection with our IPO, after reducing the amount of such tax obligations by an amount equal to the net after-tax value of any dividend proceeds retained by us on behalf of such holder in connection with the Recapitalization, in each case, in accordance with the terms of the applicable repurchase agreement. The purchase price per share for each share of common stock was equal to the price per share for the shares of common stock sold in the IPO, less an amount equal to the underwriting discount. We refer to these transactions collectively as the “Common Stock Repurchases.”

Pursuant to the Common Stock Repurchases, and based on a repurchase price of $13.195 per share, we repurchased 595,912 shares of common stock from Ravi Vig for an aggregate repurchase price of $7.9 million; 287,912 shares of common stock from Paul V. Walsh, Jr. for an aggregate repurchase price of $3.8 million; 109,648 shares from Michael C. Doogue for an aggregate repurchase price of $1.4 million; and 119,183 shares of common stock from Thomas C. Teebagy, Jr. for an aggregate repurchase price of $1.6 million.

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

The Divestiture Transactions

Consolidated Loan Agreement

We divested a majority of our ownership interest in Polar Semiconductor, LLC (“PSL”) to Sanken (the “PSL Divestiture”). Prior to the consummation of the PSL Divestiture, PSL had $66.4 million in aggregate principal amount of debt owed to us under certain intercompany loan agreements (collectively, the “Existing Allegro Loans”). As partial consideration for the recapitalization of our equity interests in PSL in connection with the PSL Divestiture, we contributed $15.0 million in aggregate principal amount of debt outstanding under the Existing Allegro Loans, terminated the balance of the Existing Allegro Loans and entered into the Consolidated Loan Agreement with PSL pursuant to which PSL issued the PSL Note to us in the amount of $51.4 million (representing the aggregate principal amount of debt outstanding under the Existing Allegro Loans prior to their termination). Interest accrues under the Consolidated Loan Agreement at a rate of 2.70% per annum. The principal amount outstanding under the Consolidated Loan Agreement, together with accrued and unpaid interest thereon, is to be repaid in six annual installments beginning on March 28, 2022, with the final payment due on March 28, 2027, provided that PSL may prepay all or any portion of such outstanding principal amount at any time without premium or penalty.

PSL LLC Agreement

In connection with the PSL Divestiture, we, Sanken and PSL amended and restated the existing limited liability company agreement of PSL (as so amended and restated, the “PSL LLC Agreement” or, for purposes of this summary, the “LLC Agreement”) to admit Sanken as a member, reflect the recapitalization of our equity interests and otherwise reflect the rights and obligations of us and Sanken (each, a “Member” and together, the “Members”) thereunder following the consummation of the PSL Divestiture.

Under the LLC Agreement, the power to manage the business and affairs of PSL is vested in a board of managers. The board of managers currently consists of five managers, three of whom are designees of Sanken, one of whom is our designee, and the last of whom is the President of PSL.

The limited liability company interests of PSL are represented by units (“Units”), which entitle the holder thereof to an ownership interest in the income, losses and capital of PSL and a share of the distributions of PSL, in each case, as set forth in the LLC Agreement. The LLC Agreement provides that distributions of cash or other assets of PSL are subject to the approval of the Board and the consent of each Member. Any distributions will be allocated to each Member in accordance with the percentage of outstanding Units held by such Member (“Unit Percentage”). As of December 25, 2020, our Unit Percentage was 30% and Sanken’s Unit Percentage was 70%. In the event of a dissolution, the assets of PSL will first be used to repay PSL’s debts (including debts owed to the Members), and any remaining assets will be distributed to the Members in accordance with their respective Unit Percentages.

Wafer Foundry Agreement and Price Support Agreement

In April 2013, AML, our wholly-owned subsidiary, entered into a wafer foundry agreement with PSL (as amended, the “Wafer Foundry Agreement”). Under the Wafer Foundry Agreement, PSL produces wafers for sale to AML in response to purchase orders AML submits on a weekly basis. Purchase orders under the Wafer Foundry Agreement are binding, provided that AML may cancel any such order subject to paying the applicable termination charges as set forth in the Wafer Foundry Agreement. Wafer and mask pricing is established by AML and PSL based on a six-month binding forecast finalized at the beginning of each new fiscal half-year period, subject to mutually agreed-upon pricing adjustments for increases or decreases in excess of a specified percentage of forecasted volumes. The Wafer Foundry Agreement also grants to PSL a non-exclusive, non-transferable, royalty-free license to use certain technology and intellectual property rights of AML to manufacture such semiconductor wafers in PSL’s Bloomington, Minnesota wafer fab facility.

The Wafer Foundry Agreement provides that PSL will reimburse AML for AML’s reasonable and verifiable costs incurred for product recalls and the sorting, inspection, replacement, repair, disposal and/or re-shipment of defective products resulting from the non-conformity of any wafer purchased from PSL, subject to an agreed-upon cap, and provided the amount of any such claim must exceed a specified de minimis amount.

As part of the Divestiture Transactions, AML and PSL amended the Wafer Foundry Agreement to, among other things, require AML to submit a rolling three-year forecast of its total production wafer requirements by process technology, to be updated on an annual basis. In the event AML does not purchase at least 90% of its annual forecasted volumes for a fiscal year, calculated on a per-quarter basis (the “Minimum Purchase Quantity”), AML will be required to pay to PSL, within 60 days following the end of the applicable fiscal year, a “shortfall amount” equal to the fixed direct cost per production wafer multiplied by the difference

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

between the actual number of production wafers purchased by AML and the Minimum Purchase Quantity. The Wafer Foundry Agreement, as amended, has an initial term of three years and may be renewed for additional one-year periods by mutual written agreement of the parties. During the fiscal year ended March 26, 2021, AML made aggregate purchases of $42.2 million from PSL pursuant to the Wafer Foundry Agreement.

As part of the Divestiture Transactions, AML and PSL also entered into a letter agreement (the “Price Support Agreement”), which provides that, during PSL’s fiscal year 2021, irrespective of whether AML meets the Minimum Purchase Quantity under the Wafer Foundry Agreement, AML will make a payment to PSL of approximately $5.9 million prior to the end of such fiscal year in cash or, at AML’s option, as a reduction of PSL’s existing debt obligations under the Consolidated Loan Agreement. We paid $5.9 million of this amount during the fiscal year ended March 26, 2021.

Transfer Pricing Agreements

As part of the Divestiture Transactions, we, Sanken, AML and PSL entered into an amended and restated transfer pricing agreement (the “A&R Transfer Pricing Agreement”), pursuant to which Sanken is obligated to make payments to PSL on a quarterly basis in such amounts as may be necessary to enable the margin of PSL’s EBIT for the most recent trailing twelve-month period for which financial statements are available over PSL’s consolidated revenues for such period (such margin, the “EBIT Margin”) to meet a target level EBIT Margin agreed upon by us, Sanken, AML and PSL. The A&R Transfer Pricing Agreement provides that we and AML are express beneficiaries of such agreement with the right to directly enforce the rights of PSL thereunder. The term of the A&R Transfer Pricing Agreement is perpetual, but may be terminated at any time upon written consent by each of us, Sanken, AML and PSL.

Letter Agreement re Consolidation of Technology Agreements

As part of the Divestiture Transactions, AML entered into a consolidation of technology agreement with Sanken and PSL (the “Technology Letter Agreement”) pursuant to which the parties confirmed their agreement regarding their respective rights and obligations relating to certain intellectual property developed pursuant to the agreements listed on Schedule 1 thereto, including the Discrete Technology Development Agreement, the IC Technology Development Agreement and the SG8 Collaboration Agreement (each as defined below under “—Other Related Party Transactions—Technology Agreements”). The Technology Letter Agreement generally covers assignments and licenses of certain intellectual property by PSL to us and Sanken; licenses by us and Sanken of certain intellectual property to PSL; intellectual property retained by PSL; and the use restrictions and enforcement mechanisms applicable to jointly owned intellectual property.

Other Related Party Transactions

Distribution of Allegro Products in Japan

In July 2007, we entered into a distribution agreement with Sanken pursuant to which we appointed Sanken to act as the exclusive distributor of our products (subject to certain exceptions for any products we and Sanken agree to exclude) in Japan (the “Japan Distribution Agreement”). The price Sanken is required to pay for our products under the Japan Distribution Agreement is set as a percentage of the selling price of such products to Sanken’s end customers. In addition, Sanken is entitled to a commission equal to a certain percentage of its Net Sales (as defined in the Japan Distribution Agreement) of design-in products. The current term of the Japan Distribution Agreement will expire on March 31, 2022, provided that the agreement will automatically renew for successive three-year periods until either party gives notice of termination at least 12 months prior to the expiration of the then-current term. Each party also has the right to terminate the Japan Distribution Agreement immediately if the other party experiences certain events of bankruptcy or insolvency, or upon the expiration of the specified cure period in the event of a default by the other party. During fiscal year 2021, Sanken purchased $104.7 million of products from us under this agreement.

Transactions Involving Sanken

The Company sells products to, and purchases in-process products from Sanken. In addition, prior to March 28, 2020, the Company also sold products for Sanken.

Net sales of the Company’s products to Sanken totaled $104.7 million during the fiscal year ended March 26, 2021. Trade accounts receivables, net of allowances from Sanken totaled $21.6 million as of March 26, 2021.

Technology Agreements

In April 2015, PSL and Sanken entered into a discrete technology development agreement (as amended, the “Discrete Technology Development Agreement”), pursuant to which the parties agreed upon the general terms under which they, from


			INNOVATION WITH PURPOSE			48

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

time to time, undertook certain activities (the “Discrete Development Activities”) to develop new technologies to be used by PSL to manufacture products for Sanken, as well as the ownership and use of such technologies following their development. In June 2018, we, PSL and Sanken entered into an amendment to the Discrete Technology Development Agreement pursuant to which the parties agreed to the assignment of all rights and obligations of PSL under such agreement to us and to certain amendments to the terms of such agreement. The Discrete Technology Development Agreement provided that the expenses for all Discrete Development Activities to be shared equally by us and Sanken on an annual basis (subject to any exceptions upon which the parties may agree from time to time). During the fiscal year ended March 26, 2021, we accrued $0.6 million included in amounts due to related party under this agreement, which was paid in the first quarter of fiscal year 2022. No further development activities or payments are expected under this agreement in the future.

In May 2009, we entered into a technology development agreement (the “IC Technology Development Agreement”) with Polar Semiconductor, Inc., the predecessor of PSL (“PSI”) and Sanken, pursuant to which the parties agreed upon the general terms under which they may, from time to time, undertake certain activities (the “IC Process Development Activities”) to develop new technologies to be used by PSI to manufacture products for us and Sanken, as well as the ownership and use of such technologies following their development. The IC Technology Development Agreement provides that the expenses for all IC Process Development Activities will be shared equally by us and Sanken on an annual basis (subject to any exceptions upon which the parties may agree from time to time), with such expenses being paid to PSI by Sanken in the form of an up-front annual fee, with PSI being responsible for any expenses that exceed the amount of such fee. The IC Technology Development Agreement will continue in effect until such time as we, PSL and Sanken mutually agree to its termination or adopt a successor agreement, or in the event we fail to agree upon the annual fee for a fiscal year within three months after the commencement of such fiscal year. During the fiscal year ended March 26, 2021, we paid fees of $1.2 million to PSL pursuant to such agreement.

In July 2014, AML entered into a technology collaboration agreement (the “SG8 Collaboration Agreement”) with PSL and Sanken, pursuant to which the parties agreed to establish a joint technology development team for the purpose of developing certain IC manufacturing technologies (the “SG8 Technology”). The SG8 Collaboration Agreement provides that AML and Sanken will be equally responsible for the costs of developing the SG8 Technology, with Sanken to reimburse us for 50% of our incurred costs. During the fiscal year ended March 26, 2021, no fees were received from Sanken pursuant to the SG8 Collaboration Agreement.

Transactions Involving Sanken Electric Europe Ltd. (“SEEL”)

During the fiscal year ended March 26, 2021 and after the PSL Divestiture, Sanken, through PSL formed SEEL to cover its distribution business in Europe. We, in connection with the transition services agreement with Sanken and PSL, paid certain costs on behalf of them, and as such, had related party accounts receivable from SEEL of $1.3 million as of the fiscal year ended March 26, 2021.

Sublease Agreement

In 2014, our subsidiary, Allegro MicroSystems Business Development, Inc. (“Allegro Business Development”), entered into a sublease agreement with Sanken pursuant to which Allegro Business Development subleases certain office building space in Japan from Sanken. The sublease automatically renews on an annual basis unless either party provides notice to the other party otherwise, and can be terminated by either party upon providing six months’ notice. We made aggregate payments of approximately $0.2 million to Sanken under the sublease agreement during the fiscal year ended March 26, 2021.

Consulting Agreement

We entered into an executive advisor agreement (the “Consulting Agreement”) with Reza Kazerounian on September 28, 2017, before Dr. Kazerounian became a member of our Board, pursuant to which we engaged Dr. Kazerounian to serve as an executive advisor to our Board and our Chief Executive Officer. On June 28, 2018, in connection with Dr. Kazerounian’s appointment to our Board, we amended the Consulting Agreement, effective as of August 1, 2018. The Consulting Agreement, as amended, provides for the following current compensation for Dr. Kazerounian’s services: (i) a monthly cash fee in the amount of $18,750 and (ii) performance bonus eligibility, payable from time to time in an amount determined by the Board (in its sole discretion). The Consulting Agreement provides that if Dr. Kazerounian’s consulting relationship is terminated by our Board, he will be entitled to a termination payment in the amount of $180,000. Our Board and Dr. Kazerounian each have the right to terminate the Consulting Agreement at any time. In addition, the Consulting Agreement contains customary confidentiality and non-disclosure restrictions, an assignment of inventions provision and employee non-solicitation and non-competition restrictions, each of which are effective during the term of the agreement and for five years after the Consulting Agreement is terminated (or such longer period as may be permitted under applicable law). During the fiscal year ended March 26, 2021, we paid aggregate fees of approximately $0.3 million to Dr. Kazerounian pursuant to the Consulting Agreement.

APPENDIX A

Non-GAAP Gross Profit and Non-GAAP Gross Margin

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. Two key metrics we consider are non-GAAP Gross Profit and non-GAAP Gross Margin. Non-GAAP Gross Profit and non-GAAP Gross Margin 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. By presenting non-GAAP Gross Profit and non-GAAP Gross Margin, 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 non-GAAP financial measures, including non-GAAP Gross Profit and non-GAAP Gross Margin, as they provide a reasonable basis for comparing our ongoing results of operations. Management believes that tracking and presenting non-GAAP Gross Profit and non-GAAP Gross Margin 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. Non-GAAP Gross Profit and non-GAAP Gross Margin 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 non-GAAP Gross Profit and non-GAAP Gross Margin, 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.

Non-GAAP financial measures, including non-GAAP Gross Profit and non-GAAP Gross Margin, have significant limitations as analytical tools. Some of these limitations are that:

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

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

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

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

•such measures do not reflect our tax expense or the cash requirements to pay our taxes;

•although depreciation and amortization are 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.

Non-GAAP Gross Profit and non-GAAP Gross Margin are supplemental measures of our performance that are neither required by, nor presented in accordance with, GAAP. Non-GAAP Gross Profit and non-GAAP Gross Margin should not be considered as substitutes for GAAP financial measures such as gross profit, gross margin, 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 non-GAAP Gross Profit and non-GAAP Gross Margin. Our presentation of non-GAAP Gross Profit and non-GAAP Gross Margin 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.


			INNOVATION WITH PURPOSE			53

APPENDIX A

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.

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

•Stock-based compensation—Represents 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 our manufacturing facility in Thailand (the “AMTC Facility”) and transitioning of test and assembly functions to our manufacturing facility in the Philippines (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 as of the end of March 2021. These costs are in addition to, and not duplicative of, the adjustments noted in note (*) below.

•Amortization of acquisition-related intangible assets—Represents 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.

•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 years 2019 and 2018. The elimination of these costs did not reduce our production capacity and therefore did not have direct effects on our ability to generate revenue. The closure and transition of the AMTC Facility was substantially completed as of the end of March 2021.

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