Information About This Proxy Statement
Why You Received this Proxy Statement. You have received these proxy materials because the Board is soliciting your proxy to vote your shares at the Annual Meeting. This proxy statement includes information that we are required to provide to you under the rules of the Securities and Exchange Commission (“SEC”) and that is designed to assist you in voting your shares.
Notice of Internet Availability of Proxy Materials. As permitted by SEC rules, we are making this proxy statement and our 2023 Annual Report available to our shareholders electronically via the Internet. On or about June 21, 2023, we mailed to our shareholders a Notice of Internet Availability of Proxy Materials (the “Notice”) containing instructions on how to access this proxy statement and our 2023 Annual Report and vote online. If you received a Notice by mail, you will not receive a printed copy of the proxy materials in the mail unless you specifically request them. Instead, the Notice instructs you on how to access and review all of the important information contained in the proxy statement and 2023 Annual Report. The Notice also instructs you on how you may submit your proxy over the Internet. If you received a Notice by mail and would like to receive a printed copy of our proxy materials, you should follow the instructions for requesting such materials contained on the Notice.
Printed Copies of Our Proxy Materials. If you received printed copies of our proxy materials, then instructions regarding how you can vote are contained on the proxy card or voting instruction form included in the materials.

Sustainability
| The future is efficient, and we are helping power the development of safe and sustainable technologies of tomorrow—today. Our products are designed to create positive environmental and social impacts by helping our customers address global challenges related to carbon emissions, energy efficiency, and clean, renewable energy.

Our sensor and power semiconductors address critical global challenges related to energy efficiency, vehicle emissions, and clean and renewable energy.
•Our Current Sensor Integrated Circuits (“ICs”) provide a low loss means to measure current in motion control and electrification systems, greatly reducing the power consumption in these applications.
•Our Brushless DC Motor Driver ICs facilitate the transition from inefficient brushed and single-phase motors to electrically efficient 3-phase motors, resulting in significant power consumption savings in data centers and cars.
•Our Engine and Transmission Sensor ICs greatly enhance the efficiency of internal combustion vehicles, resulting in reduced CO2 emissions and lower gasoline consumption.

| INNOVATION WITH PURPOSE | 4

CORPORATE RESPONSIBILITY AND SUSTAINABILITY
•Our highly integrated and embedded solutions, like our Current Sensor ICs, Angle Sensor ICs, and Brushless DC Fan Driver ICs, typically enable elimination of additional components in the end-application, reducing electronic waste.

Making an Impact: Product Highlights

We possess a long track record of innovations that have dramatically improved the energy efficiency of powertrain, safety, and comfort systems. Our innovative technologies have also led to an estimated 2.6 million tons* of avoided emissions, a number that is expected to continue to grow alongside projected growth in the electric vehicle (“EV”) market.
A combination of up to 15 ICs per car enables electronic power steering (“EPS”) systems to save upwards of 12 gallons of gas per vehicle per year compared to hydraulic steering systems. Since 2010, Allegro technologies have helped save an estimated 7.5 million tons* of CO2 emissions worldwide by enabling EPS systems.
Allegro’s speed-sensor ICs were used to create the first speed and direction crank sensor for stop/start engine control. These sensors are used to control a variety of functions, including a fuel injection and ignition timing function that increases the reach of a vehicle’s gasoline use in miles per gallon by 8%. Allegro sensor ICs have helped save 2.12 billion gallons of gas, an amount approximately equivalent to 21.2 million tons** of CO2.

Social Responsibility
| We invest in our employee innovators. Our global team collaborates to solve some of the biggest problems facing the world today. That is why we foster a culture of inclusion, development, and engagement.

We believe in innovation with purpose, and our success is a result of the dedication, talent, and commitment of our employees. We are an equal opportunity employer, and we are committed to fostering diversity, inclusivity, and global collaboration to fuel our innovation. We continue to invest in the development of our employees and to recruit new talent globally from a diverse slate of candidates across all functions and levels of the organization. The diversity of our teams, together with their unique ideas and contributions, enables us to work together toward Allegro’s vision and mission.
We are committed to cultivating a diverse workforce comprised of individuals with different backgrounds, passions, and skill sets as we collaborate to innovate with purpose. We understand that a holistic commitment to diversity necessitates more than recruiting diverse talent – it requires the cultivation of a workforce that is safe, creative, and collaborative and where there are equitable opportunities for every employee. We established a diversity, equity and inclusion (“DEI”) council that represents our global workforce, and helps guide our DEI efforts and expand our DEI roadmap. We established two new employee resource groups, Early Career and Women@Allegro. We have organizational metrics to monitor senior leadership, management, hiring and technical hiring by gender globally. We measure our population and hiring by race and ethnicity in the U.S.

Governance
| Our management and Board are committed to furthering our ESG program and are highly engaged in the work to maintain alignment of our long-term strategy and operations with these core values and goals.

We formed an ESG Steering Committee during our 2022 fiscal year to lead these sustainability efforts. The Committee has Executive Sponsorship from our SVP, General Counsel and Corporate Secretary. The committee is a cross-functional team comprised of leaders and subject matter experts from across the Company. The ESG Steering Committee collaborates with our full-time ESG team to manage and oversee communications about sustainability topics with employees, investors, customers, suppliers, and other stakeholders. In addition, the committee works to monitor and assess our sustainability developments and to expand our awareness of ESG priorities by fostering a culture of commitment to sustainability within Allegro. As part of this work, they consider current and emerging ESG trends that may affect the Company or are otherwise relevant to our organization and stakeholders and make recommendations for how we can address these trends to ensure compliance and the success of our forward-looking initiatives.
On a quarterly basis, senior management reports on key ESG activities to the Board’s Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee provides direct oversight on ESG initiatives and reviews regular updates on our strategy. Each year, our Board dedicates one of their scheduled meetings to matters related to the governance and promotion of ESG topics and initiatives at Allegro. They are highly engaged in our ESG strategy and are involved in instituting a formal accountability process for our five goals that help inform our ESG strategy: maximize the positive impact of our products; minimize our impact on the planet; engage our supply chain to advance sustainability; build a diverse and innovative workforce; and cultivate opportunities in local communities.
Cybersecurity
We have a robust cybersecurity program built around educating Allegro employees so that they understand how and why they must remain vigilant in promoting comprehensive cybersecurity throughout the Company. We also have incident response procedures in place and comply with the EU General Data Protection Regulation. By maintaining these procedures and a posture of vigilance, we work collectively to protect the data and resources not only of the Company, but also of Allegro’s employees, customers, and vendors, while promoting a culture of digital security throughout the Company. The VP, Chief Information Officer periodically briefs the Board on cybersecurity matters.
We intend to monitor our activities and achievements in these areas and report on them on our ESG webpage located at allegromicro.com/en/about-allegro/corporate-responsibility. We encourage our employees, community members, shareholders and other stakeholders to check this webpage for updates as we work to further our efforts and realize important results in these critical areas.

Your most recent proxy card or Internet or telephone proxy is the one that is counted.

If your shares are held in “street name,” you may change or revoke your voting instructions by following the specific directions provided to you by your bank, broker or other nominee, or you may vote online at the Annual Meeting.
9. Who will count the votes? Is my vote confidential?
A representative of Computershare will act as Inspector of Elections, supervise the voting, decide the validity of proxies, and receive and tabulate proxies. As a matter of policy, we keep confidential all shareholder meeting proxies, ballots and voting tabulations that identify individual shareholders. In addition, the vote of any shareholder is not disclosed except as may be necessary to meet legal requirements.
10. What if I do not specify how my shares are to be voted?
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. For beneficial holders, proxies submitted without voting instructions could result in broker non-votes for certain matters. See “What are broker non-votes and do they count for determining a quorum?” below for additional information.
11. Will any other business be conducted at the Annual Meeting?
We do not know of any other business that will be presented at the Annual Meeting. However, if any other matter properly comes before the shareholders for a vote at the Annual Meeting, the proxy holders named on the Company’s proxy card will have the discretionary authority to vote your shares in accordance with their best judgment.
12. Why hold a virtual meeting instead of a physical meeting?
In order to make the meeting accessible to all shareholders, our Board has decided to hold a virtual Annual Meeting. With this live, online webcast format, we believe we will provide our shareholders with substantially the same opportunities to participate as you would have at an in-person meeting.
13. What if I have trouble accessing the Annual Meeting virtually?

QUESTIONS AND ANSWERS ABOUT THE 2023 ANNUAL MEETING OF SHAREHOLDERS
14. How many votes are required for the approval of the proposals to be voted upon and how will abstentions and broker non-votes be treated?

Proposal | Votes required | Effect of Votes Withheld / Abstentions and Broker Non-Votes
Proposal 1: Election of Directors | A plurality of the votes properly cast. This means that the three nominees receiving the highest number of affirmative “FOR” votes will be elected as Class III Directors. | Votes withheld and broker non-votes will have no effect on the outcome because they are not considered votes cast.
Proposal 2: Ratification of Appointment of Independent Registered Public Accounting Firm | The affirmative vote of the holders of a majority in voting power of the votes properly cast. | Abstentions and broker non-votes, if any, will have no effect on the outcome because they are not considered votes cast. We do not expect any broker non-votes on this proposal.
Proposal 3: Advisory Vote on Executive Compensation | The affirmative vote of the holders of a majority in voting power of the votes properly cast. | Abstentions and broker non-votes will have no effect on the outcome because they are not considered votes cast.

15. What is a “vote withheld” and an “abstention” and how will votes withheld and abstentions be treated?
A “vote withheld,” in the case of the proposal regarding the election of directors, or an “abstention,” in the case of the proposal regarding the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm and the approval, on an advisory basis, of our executive compensation represent a shareholder’s affirmative choice to decline to vote on such proposal. Votes withheld and abstentions are counted as present and entitled to vote for purposes of determining a quorum. Votes withheld have no effect on the election of directors. Abstentions have no effect on the ratification of the appointment of PricewaterhouseCoopers LLP or the approval, on an advisory basis, of our executive compensation.
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 PricewaterhouseCoopers 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 and the approval, on an advisory basis, of our executive compensation. Broker non-votes do 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.

| INNOVATION WITH PURPOSE | 14

QUESTIONS AND ANSWERS ABOUT THE 2023 ANNUAL MEETING OF SHAREHOLDERS
PROPOSALS TO BE VOTED ON
Proposal 1: Election of Directors
We currently have 11 directors on our Board. At the Annual Meeting, three Class III Directors, Andrew G. Dunn, Richard R. Lury, and Susan D. Lynch are to be elected to hold office until the 2026 Annual Meeting of Shareholders and until each such director’s respective successor is elected and qualified or until each such director’s earlier death, resignation or removal.
The proposal regarding the election of directors requires the approval of a plurality of the votes properly cast. This means that the three nominees receiving the highest number of affirmative “FOR” votes will be elected as Class III 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 Third Amended and Restated Certificate of Incorporation, the Board is currently divided into three classes with staggered, three-year terms. At each annual meeting of shareholders, the successors to directors with expiring terms 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 III, whose term currently expires at the Annual Meeting and whose subsequent term will expire at the 2026 Annual Meeting of Shareholders; Class I, whose term will expire at the 2024 Annual Meeting of Shareholders; and Class II, whose term will expire at the 2025 Annual Meeting of Shareholders. The current Class III Directors are Andrew G. Dunn, Richard R. Lury, and Susan D. Lynch; the current Class I Directors are Katsumi Kawashima, Reza Kazerounian, Joseph R. Martin and Vineet Nargolwala; and the current Class II Directors are Yoshihiro (Zen) Suzuki, David J. Aldrich, Kojiro (Koji) Hatano and Paul Carl (Chip) Schorr IV. In preparation for the initial public offering of our Common Stock in 2020 (the “IPO”), we entered into a stockholders agreement with Sanken Electric Co., Ltd. (“Sanken”) and OEP SKNA, L.P. (the “OEP Investor”), a fund affiliated with One Equity Partners (“OEP”). The stockholders agreement was amended and restated by the parties as of June 16, 2022 (as amended and restated, the “Stockholders Agreement”). Pursuant to the rights provided in the Stockholders Agreement, Messrs. Hatano, Kawashima and Lury were each designated by Sanken (each as a Sanken Director, as defined below); Messrs. Dunn and Schorr were each designated by the OEP Investor (each as an OEP Director, as defined below); Messrs. Aldrich and Martin and Ms. Lynch were each designated by the OEP Investor (each as an OEP Independent Director, as defined below); Mr. Kazerounian was designated by Sanken and the OEP Investor jointly (as an OEP-Sanken Joint Director, as defined below); and Mr. Suzuki was designated by the Board’s Nominating and Corporate Governance Committee (as the Nom/Gov Director, as defined below). As a result of the Stockholders Agreement 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, including the definitions of Sanken Director, OEP Director, OEP Independent Director, OEP-Sanken Joint Director and Nom/Gov Director, see “Corporate Governance—Stockholders Agreement” on page 27.
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. Dunn and Lury and Ms. Lynch as a Class III Director. In the event that any of the nominees 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. Dunn or Lury or Ms. Lynch will be unable to serve if elected. Each of the nominees has consented to being named in this proxy statement and to serve if elected.
Vote Required
The proposal regarding the election of directors requires the approval of a plurality of the votes properly cast. This means that the three nominees receiving the highest number of affirmative “FOR” votes will be elected as Class III Directors.

RECOMMENDATION OF THE BOARD OF DIRECTORS
The Board unanimously recommends a vote FOR the election of each of the below Class III Director nominees.

Nominees For Class III Director (terms to expire at the 2026 Annual Meeting)
The principal occupations and business experience, for at least the past five years, of each Class III Director nominee for election at the Annual Meeting are as follows:

Andrew G. Dunn
Age: 43 Board Committees: R&D and Strategy | Mr. Dunn has served as a member of our Board since 2017. Mr. Dunn is a Managing Director at OEP.

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 PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending March 29, 2024. Our Board has directed that this appointment be submitted to our shareholders for ratification at the Annual Meeting. Although ratification of our appointment of PricewaterhouseCoopers LLP is not required, we value the opinions of our shareholders and believe that shareholder ratification of our appointment is a good corporate governance practice.
PricewaterhouseCoopers LLP has been engaged as our independent registered public accounting firm since June 7, 2022, including for the fiscal year ended March 31, 2023. Prior to that, Grant Thornton LLP served as our independent registered public accounting firm, including for the fiscal year ended March 25, 2022. Neither of the accounting firms nor any of either firm’s members have 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. We expect representatives of PricewaterhouseCoopers LLP to be present at the Annual Meeting. Representatives of PricewaterhouseCoopers LLP will have an opportunity to make a statement if they so desire and are expected to be available to respond to appropriate questions from shareholders.
In the event that the appointment of PricewaterhouseCoopers LLP is not ratified by the shareholders, the Audit Committee will consider whether it is appropriate to select another independent registered public accounting firm, but it will not be obligated to do so. Even if the appointment of PricewaterhouseCoopers 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 best interest of the Company.
Changes in Certifying Accountant
On June 7, 2022, our Audit Committee dismissed Grant Thornton LLP as the Company’s independent registered public accounting firm. The reports of Grant Thornton LLP on the Company’s consolidated financial statements and internal control over financial reporting, which were included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 25, 2022, and the report on the Company’s consolidated financial statements, which was included in the Company’s Annual Report on Form 10‑K for the fiscal year ended March 26, 2021, did not contain an adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.
During the Company’s fiscal years ended March 25, 2022 and March 26, 2021, and the subsequent interim period through June 7, 2022, there were: (i) no disagreements within the meaning of Item 304(a)(1)(iv) of Regulation S-K between the Company and Grant Thornton LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to Grant Thornton LLP’s satisfaction, would have caused Grant Thornton LLP to make reference thereto in Grant Thornton LLP’s reports; and (ii) no “reportable events” within the meaning of Item 304(a)(1)(v) of Regulation S-K.
We previously provided Grant Thornton LLP with a copy of the above disclosures, as included in our Current Report on Form 8-K filed with the SEC on June 10, 2022, and requested that Grant Thornton LLP furnish us with a letter addressed to the SEC stating whether Grant Thornton LLP agreed with the statements made by us in response to Item 304(a) of Regulation S-K and, if not, stating the respects in which it does not agree. A copy of Grant Thornton LLP’s letter, dated June 9, 2022, is attached as Exhibit 16.1 to that Current Report on Form 8-K.
On June 7, 2022, our Audit Committee approved the engagement of PricewaterhouseCoopers LLP as the Company’s independent registered public accounting firm for the fiscal year ending March 31, 2023. During the Company’s fiscal years ended March 25, 2022 and March 26, 2021, and the subsequent interim period through June 7, 2022, neither the Company nor anyone on its behalf has consulted with PricewaterhouseCoopers LLP regarding: (i) the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements, and neither a written report nor oral advice was provided to the Company that PricewaterhouseCoopers LLP concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing, or financial reporting issue; (ii) any matter that was the subject of a disagreement within the meaning of Item 304(a)(1)(iv) of Regulation S-K; or (iii) any “reportable event” within the meaning of Item 304(a)(1)(v) of Regulation S-K.

PROPOSAL TWO: RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
Vote Required
This proposal requires the affirmative vote of the holders of a majority in voting power of the votes properly 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 PricewaterhouseCoopers LLP, we do not expect any broker non-votes in connection with this proposal.

PROPOSAL 3: ADVISORY VOTE ON THE COMPANY’S EXECUTIVE COMPENSATION
Proposal 3: Advisory Vote on the Company’s Executive Compensation
Pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act and Section 14(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), we are providing our shareholders with the opportunity to vote to approve, on a non-binding, advisory basis, the overall compensation of our named executive officers as disclosed in “Executive and Director Compensation” section of this proxy statement. This advisory vote is commonly referred to as “say-on-pay.”
A substantial percentage of our named executive officers’ compensation is directly tied to stock performance and the attainment of financial and other performance measures the Board believes promote long-term shareholder value and position us for long-term success. As described more fully in the Compensation Discussion and Analysis, the mix of fixed and performance-based compensation, the terms of our incentive compensation programs, and the weighting of variable compensation more heavily toward equity awards, are all designed to enable us to attract and retain top talent and align the interests of our executive officers with those of our shareholders, while balancing risk and reward. The Compensation Committee and the Board believe the design of the programs, and the compensation awarded to the named executive officers under the current programs, fulfills these objectives.
Although the vote is advisory and non-binding, the Board and the Compensation Committee will carefully consider the outcome of the vote in connection with their ongoing evaluation of the Company’s compensation programs. We currently intend to hold say-on-pay votes on executive compensation annually until the next vote to determine the frequency of such an advisory vote in 2028. Accordingly, we anticipate the next say-on-pay vote will be held at the Company’s 2024 Annual Meeting of Shareholders.
We are asking our shareholders to approve the compensation of our named executive officers by voting “FOR” the following resolution:
“RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion, is hereby APPROVED.”
Vote Required
This proposal requires the affirmative vote of the holders of a majority in voting power of the votes properly cast. Abstentions 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.

RECOMMENDATION OF THE BOARD OF DIRECTORS
The Board unanimously recommends a vote “FOR” the approval, on an advisory basis, of the Company’s executive compensation.

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 31, 2023.

The Audit Committee reviews these requests and advises management if the Audit Committee approves the engagement of the independent registered public accountants.

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. 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 shareholders 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, the Company has agreed 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 shareholders at which directors are to be elected, and at each annual meeting of our shareholders 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 shareholders or does not otherwise comply with any requirements of our Third Amended and Restated Certificate of Incorporation or our Second Amended and Restated Bylaws (the “Bylaws”).
In addition, the Stockholders Agreement provides each of Sanken and the OEP Investor 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 shareholders and has recommended that the shareholders 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 shareholder in a privately negotiated sale solely between such selling shareholder 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

| INNOVATION WITH PURPOSE | 28

Investor) ceasing to own any shares of our Common Stock. Notwithstanding the foregoing, if the OEP Investor ceases to be entitled to any right or benefit under the Stockholders Agreement because the OEP Investor and its affiliates cease to beneficially own, directly or indirectly, either (A) at least five percent (5%) of the issued and outstanding shares of Common Stock, or (B) any shares of Common Stock, then the Stockholders Agreement will not terminate, and instead, any such right or benefit will automatically become a right or benefit of the Nominating and Corporate Governance Committee for so long as the Stockholders Agreement remains in effect, and the Nominating and Corporate Governance Committee shall have the right to enforce any such rights or benefits mutatis mutandis as though it were the OEP Investor under any applicable provision (but without regard to any share ownership requirements set forth therein), leaving all of Sanken’s and the Company’s obligations in respect of any such provisions in full force and effect. In addition, if the OEP Investor and its affiliates cease to beneficially own, directly or indirectly, at least five percent (5%) of the Company’s issued and outstanding shares of Common Stock, then the OEP Investor will no longer need to obtain Sanken’s prior written consent before requesting removal of an OEP Director, or designating a replacement as either an OEP Director or an OEP Independent Director.
Director Independence
Our Common Stock is listed on the Nasdaq Global Select Market (“Nasdaq”). Under 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 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 J. Aldrich, Andrew G. Dunn, Richard R. Lury, Susan D. Lynch, Joseph R. Martin and Paul Carl (Chip) Schorr IV, representing six of our 11 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 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 shareholders, and the transactions involving them described in the section entitled “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 shareholders. 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 shareholder interests through the exercise of sound

| INNOVATION WITH PURPOSE | 29

CORPORATE GOVERNANCE
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.
Shareholders 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 shareholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates submitted by others.
Communications from Shareholders
The Board will give appropriate attention to written communications that are submitted by shareholders and will respond if and as appropriate. Our Secretary is primarily responsible for monitoring communications from shareholders and for providing copies or summaries to the directors as our Secretary 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 or personal grievances. Shareholders who wish to send communications on any topic to the Board should address such 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 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 Vineet Nargolwala 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. Nargolwala, 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. The Board does not currently have 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.

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 the “Governance” section under “Documents & Charters.” In addition, we have or intend to post on our website all disclosures that are required by law or Nasdaq rules concerning any amendments to, or waivers from, any provision of the code.
Attendance by Members of the Board at Meetings
There were nine meetings of the Board during the fiscal year ended March 31, 2023. During the fiscal year ended March 31, 2023, 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, with the exception of Mr. Kawashima.
Under our Corporate Governance Guidelines, which are available on our investor relations website at investors.allegromicro.com in the “Governance” section under “Documents & Charters,” 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 serves (including separate meetings of the non-management and 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 directors will attend, absent compelling circumstances. All of our directors attended the 2022 virtual annual meeting.

CEO Transition in Fiscal Year 2023
Mr. Nargolwala joined the Company as President and Chief Executive Officer on June 13, 2022, succeeding Mr. Vig, who retired from the Company, effective the same day.
Employment Agreement with Mr. Nargolwala
In connection with Mr. Nargolwala’s hire, the Company entered into an employment agreement with Mr. Nargolwala (the “Employment Agreement”). Under the Employment Agreement, Mr. Nargolwala’s annual base salary was set at $600,000, and his target award under the Company’s Annual Incentive Plan (“AIP”) was set at 110% of his annual base salary (prorated for fiscal year 2023 based on the partial year served, with the pro-rated amount being at least equal to 110% of his annual base salary). In addition to the prorated annual bonus that Mr. Nargolwala received in 2023, under the terms of the Employment Agreement, Mr. Nargolwala also received a $217,000 signing bonus (the “Signing Bonus”). In the event that Mr. Nargolwala voluntarily resigns without Good Reason or the Company terminates his employment for Cause (as each such capitalized term is defined in the Employment Agreement) before July 1, 2023, Mr. Nargolwala will be required to repay the full Signing Bonus. In the event that Mr. Nargolwala voluntarily resigns without Good Reason or the Company terminates his employment for Cause between July 1, 2023 and July 1, 2024, Mr. Nargolwala will be required to repay a prorated amount of the Signing Bonus based upon the number of months worked during the two-year period ending on July 1, 2024.
Under the Employment Agreement, on June 13, 2022, Mr. Nargolwala received a one-time grant of time-based restricted stock units (“RSUs”) representing a number of shares of the Company’s Common Stock having a grant date fair value of $4 million divided by the closing price of a share of the Company’s Common Stock on Nasdaq on that date (“Sign-On Equity Award”). The RSUs vested as to 60% of the underlying shares on the first anniversary of the grant date, and the remaining 40% of the underlying shares will vest on the second anniversary of the grant date, subject to Mr. Nargolwala’s continued employment with the Company through the vesting date.
In addition, under the Employment Agreement, on August 1, 2022, Mr. Nargolwala received an initial equity award representing a number of shares of Common Stock having a grant date fair value of $4 million divided by the closing price of a share of the Company’s Common Stock on Nasdaq on that date (the “Initial Equity Award”). Forty percent of the Initial Equity Award was granted in the form of RSUs that will vest 25% per year over four years on the anniversary of the grant date, subject to Mr. Nargolwala’s continued employment with the Company through the vesting date. The remaining 60% of the total Initial Equity Award was granted in the form of performance-based restricted stock units (“PSUs”) that vest based on achievement of performance goals and continued service over a three-year performance period.

EXECUTIVE AND DIRECTOR COMPENSATION
The material terms and conditions of severance provisions outlined in the Employment Agreement for Mr. Nargolwala are summarized under the heading “Severance and Employment Agreements” presented on page 59 of this proxy statement.
Retirement of Mr. Vig
Mr. Vig retired from the Company on June 13, 2022. To ensure a smooth and orderly transition to the new CEO, per the terms of his Second Amended and Restated Severance Agreement (the “Severance Agreement”), and in consideration of Mr. Vig’s availability to the Company for a period of time following his retirement, general release of claims and compliance with certain obligations, including non-solicitation and non-disparagement covenants:
•All PSUs held by Mr. Vig at the time of his retirement remained outstanding and eligible to vest in accordance with their terms, based on the achievement of applicable performance conditions that were fixed as of the time of his retirement, provided that in no event will the number of shares delivered to Mr. Vig following vesting have a fair market value on the date of delivery that is less than the number of earned shares multiplied by a designated stock price that is equal to the greater of the fair market value on the date of delivery, or the trailing 20-day average of the share price as of Mr. Vig’s retirement date (the “PSU Modification”).

Executive Summary
2023 Business Results
During fiscal year 2023, Allegro sharpened its focus on large, fast-growing automotive and industrial markets. These markets are being transformed by the mega trends of electrification and automation that will play out over the next decade and intersect with our market leading sensor and power product portfolio and technical expertise. In fiscal year 2023, continued strong momentum in strategic growth areas including e-Mobility, which we define as the electrification of vehicles and the increasing adoption of safety-related advance driver assistance systems known as ADAS, and select industrial markets drove 27% year-over-year growth in sales to a record $974 million. Design win momentum increased significantly, with approximately two-thirds of our wins coming from strategic growth areas, where we have also aligned our investments in research and development and customer support capabilities. We also expanded gross margins and achieved U.S. generally accepted accounting principles (“GAAP”) and non-GAAP earnings growth rates of more than two times the sales growth rate, demonstrating the leverage in our operating model.
The following sets forth certain details of our financial results for fiscal year 2023 and the returns delivered to shareholders, compared to certain benchmarks, for fiscal year 2023 and the year-over-year change from fiscal year 2022:

Important 2023 Compensation Actions
Our Compensation Committee, which consists entirely of independent directors, sets the compensation of our NEOs. In fiscal year 2023, the Compensation Committee took the following actions with respect to the compensation of our NEOs:
•As part of our standard annual review cycle, reviewed the base salaries for our NEOs, approving increases of 4.2%, 5.6%, 2.6% and 4.0% for Ms. Briansky and Messrs. Glover, Doogue, and Vig, respectively;
•As part of our standard annual review cycle, reviewed the annual target bonus opportunities for our NEOs under the AIP, increasing Mr. Doogue’s target bonus opportunity from 70% to 75% of base salary;
•Approved AIP performance metrics, weighting non-GAAP Operating Income, further adjusted for the operational impact of acquisitions (“Performance EBIT”) performance at 70% and revenue performance at 30%; and
•Approved Long-Term Incentive (“LTI”) compensation, consisting of a combination of RSUs and PSUs to provide strong links to long-term shareholder value creation and promote alignment with investors.
As illustrated below, our executive compensation program utilizes annual and long-term incentive awards, including awards that are contingent on Company performance relative to our key performance metrics. The pay mix charts set forth below are based on target compensation and include base salary, target annual bonus under the AIP, and annual long-term equity-based awards at target. Fiscal year 2023 compensation for our CEO presented below is for Mr. Nargolwala since he was our CEO as of the end of fiscal year 2023. The “Other NEO” average includes Ms. Briansky and Messrs. D’Antilio, Glover and Doogue.

Compensation Philosophy and Objectives
The overall objective of our compensation program is to encourage and reward the creation of sustainable, long-term value for our stakeholders. We pursue this objective via:
•Alignment with long-term shareholders’ interests. We believe our executives’ interests are more directly aligned with our shareholders’ interests when compensation programs emphasize an appropriate balance of short- and long-term financial performance and align to the characteristics of our target markets.
•External Competitiveness. We believe an executive’s total pay should be competitive with companies of similar industry, size and complexity at the target performance level in order to attract qualified executives, motivate performance and retain, develop and reward executives with the abilities and skills needed to foster long-term value creation.
•Motivating achievement of financial goals and strategic objectives. We believe an effective way to create value over the long term is to make a significant portion of an executive’s overall pay dependent on the achievement of our short- and long-term financial goals and strategic objectives.
•Rewarding superior performance. We believe that although an executive’s total compensation should be tied to achievement of financial goals and strategic objectives and should be competitive with companies of similar industry, size and complexity at the target performance level, performance that exceeds target should be appropriately rewarded. We also believe there should be downside risk of below-target payouts if our financial performance is below target and if we do not achieve our financial goals and strategic objectives.
•Responding to change. We believe that as our industry continues to evolve and our opportunities for competitive business advantages change over time, we must also continue to evolve in order to continue to create value. Our compensation programs must likewise be tailored to our strategic priorities (which may require changing the performance measures in our incentive plans from time to time) and our current outlook (which may impact how we calibrate incentive plan payouts to various levels of performance).
Compensation Governance and Best Practices
We are committed to maintaining strong governance standards with respect to our compensation programs, procedures, and practices. For example:
What we do

√ | Our executive compensation decisions are made by the independent members of our Board or by our Compensation Committee, which is made up exclusively of independent members.
√ | Our Compensation Committee has retained an independent executive compensation consulting firm to provide objective analysis, advice and information.

| INNOVATION WITH PURPOSE | 39

EXECUTIVE AND DIRECTOR COMPENSATION

√ | We make a significant portion of each NEO’s overall compensation dependent on our performance measures against pre-determined targets for short- and long-term financial performance measures, targets that we believe are challenging, yet achievable.
√ | We provide a significant portion of each NEO’s overall compensation opportunity in the form of at-risk, equity-based incentive awards to establish a strong link between an NEO’s compensation and our stock price performance.
√ | Our NEOs and independent members of our Board who receive compensation from the Company for their Board service are subject to robust stock ownership guidelines.
√ | Our 2020 Omnibus Incentive Compensation Plan (the “2020 Plan”) provides for recoupment of incentive awards in the event of a material financial restatement due to material noncompliance with financial reporting requirements or breach of restrictive covenants.

What we don’t do

X | We do not provide our NEOs with material executive perquisites.
X | We do not permit hedging or pledging of the Company’s equity securities by any officers, directors, or employees.
X | We do not provide any tax gross ups to our NEOs, including in the event of a change in control of the Company (a “change in control”) or otherwise.
X | We do not provide for single-trigger vesting of unvested equity awards in the event of a change in control.
X | We currently have no outstanding stock option awards, but if we choose to grant option awards in the future, we do not permit the repricing or back-dating of stock option awards.

Role of the Compensation Committee, Compensation Consultant and Management
In setting executive compensation, the Compensation Committee considers a number of factors, including the CEO’s recommendations (other than with respect to his own compensation), the recommendations and competitive market data and analysis provided by the Compensation Committee’s independent compensation consultant, Company performance and each executive’s impact on that performance, each executive’s relative scope of responsibility and potential, each executive’s individual performance and demonstrated leadership, and each executive’s professional experience and tenure with the Company. The Compensation Committee also considers prior fiscal year adjustments to executive compensation, historical payments under our AIP and our historical equity award grant practices. The Compensation Committee has the final authority to approve annual compensation packages for all executives.
Prior to the start of each fiscal year, we develop Company performance metrics aligned with our annual operating plan for our employees, including our NEOs. These goals represent key performance objectives that are incorporated into the AIP framework and then submitted to the Compensation Committee for consideration and approval. After our fiscal year-end financial results are available, the Compensation Committee approves annual bonus payout amounts under our AIP for our executives for the just-completed fiscal year.
The Compensation Committee has engaged Meridian Compensation Partners, LLC (“Meridian”), an independent compensation consulting firm, to provide research and analysis and to make recommendations on the form and level of executive compensation. The Compensation Committee sought input from Meridian on executive compensation matters for the 2023 fiscal year, including the design and competitive position of our executive compensation program, our peer group (see the following page for additional information on our peer group), appropriate compensation levels, and evolving compensation trends.
Based on its consideration of the various factors set forth in the rules promulgated by the SEC and Nasdaq rules, the Compensation Committee has determined that the work performed by Meridian has not raised any conflict of interest.
Competitive Positioning
We perform a competitive market analysis of our executive compensation programs annually and director compensation programs biennially to ensure that the total compensation packages of our executive officers and the non-employee members of our Board are within a reasonably competitive range of companies of similar industry, size and complexity. In connection with its fiscal year 2023 compensation actions and decisions, the Compensation Committee considered a competitive market analysis prepared by Meridian in February of 2022 (see below for more information on the competitive market analysis). The Meridian analysis determined that the NEOs’ cash compensation, comprised of annual base salary, plus annual target bonus

| INNOVATION WITH PURPOSE | 40

EXECUTIVE AND DIRECTOR COMPENSATION
under the AIP, approximated the 50th percentile relative to competitive market data. The analysis also found that the equity incentive awards that we granted during fiscal year 2022 approximated the 50th percentile in aggregate and, on an executive-to-executive basis, ranged from the 30th to the 75th percentile. This analysis excluded compensation for Mr. Nargolwala, who did not join the Company until June 2022 and whose compensation package relied on competitive data and was designed to induce him to join the Company.
The Compensation Committee considered these results in its compensation program decision-making for fiscal year 2023.
Competitive Market Analysis
In February 2022, Meridian conducted a competitive market analysis to support the Compensation Committee in connection with its executive and non-employee director compensation decisions for fiscal year 2023. To develop an understanding of the competitive marketplace, the Compensation Committee reviewed the executive compensation practices of a group of publicly traded companies (the “Peer Group”) based on compensation data gathered from publicly available filings. Meridian worked with the Compensation Committee to review the Company’s Peer Group.
In determining the Peer Group to be utilized in making compensation decisions for fiscal year 2023, the Compensation Committee and Meridian reviewed and considered factors such as industry, total revenue, market capitalization, growth, and profitability margins. The Peer Group was selected based on the evaluation of all of these factors, and consisted of the following 14 companies:

Peer Group
Cirrus Logic, Inc. | ON Semiconductor Corporation
Diodes Incorporated | Power Integrations, Inc.
Lattice Semiconductor Corporation | Rambus Inc.
MACOM Technology Solutions Holdings, Inc. | Semtech Corporation
MaxLinear, Inc. | Silicon Laboratories Inc.
Microchip Technology Incorporated | Synaptics Incorporated
Monolithic Power Systems, Inc. | Wolfspeed, Inc. (formerly Cree, Inc.)

As compared to our prior Peer Group composition, the Compensation Committee determined to remove Brooks Automation, Inc. (now Azenta, Inc.) following the divestiture of its semiconductor solutions group, Inphi Corporation following its acquisition by Marvell Technology Group, and Analog Devices, Inc. due to its much higher revenue, headcount and market capitalization as compared to our own. The Compensation Committee added Rambus Inc. due to its industry relevance and to position the Peer Group median revenue, headcount and market capitalization closer to our own.
As indicated in the table below, at the time of the competitive market analysis in February 2022, our revenue approximated the Peer Group 29th percentile, our headcount the 79th percentile, and our market capitalization the 50th percentile.

The Compensation Committee uses the market analysis as a reference point to ensure that our executive compensation program is competitive with market practice for our Peer Group. In the case of each executive officer, the Compensation Committee compares the overall compensation of each individual against the compensation data developed through the market analysis, if their position is sufficiently similar to the positions identified in the data to make the comparison meaningful. The Compensation Committee reviews a full array of competitive market data as part of this comparison process rather than isolating a particular percentile with respect to any portion of the executives’ pay. Ultimately, the Compensation Committee’s decisions with respect to each executive’s total compensation, and each individual compensation element, are based in large part on its assessment of the Company’s and individual’s performance, as well as other factors, such as internal equity across the organization.
Compensation Elements
We use the following key elements to compensate our NEOs:

Compensation Element | Purpose | Timing of Payment(s)
Base Salary Representing the only fixed element of total direct compensation | •Provide a competitive fixed rate of pay relative to similar positions in the market. •Enable the Company to attract and retain critical executive talent. | •Paid bi-weekly throughout the year
Annual Incentive Plan (AIP) Cash-settled and tied to the achievement of short-term (one year or less) Company financial and / or strategic goals | •Focus executive officers on achieving progressively challenging short-term performance goals that align with the Company’s annual operating plan and result in long-term value creation. | •Lump-sum payment in the first quarter of the following fiscal year for executives as of the end of the fiscal year
Long-Term Incentives Comprised of a selection of equity instruments and vesting criteria tailored to promote long-term alignment of pay with shareholders | •Focus our executive officers on long-term relative and absolute performance goals that strongly align with and drive shareholder value creation, as well as support the Company’s leadership retention strategy. | •Annual equity awards generally vest over a three or four-year period from date of grant

Variation in competitive positioning among executives is to be expected, to recognize differences in individual performance, tenure, or scope of responsibility relative to market. However, we generally position each compensation element within a competitive range (+/- 15% for Base Salary and AIP target compensation, +/- 20% for grant date fair value of Long-Term Incentives) of the market 50th percentile.

Fiscal Year 2023 Base Salaries
NEO base salaries are an important part of their total compensation package and are intended to reflect their respective positions, duties, and responsibilities. Our Compensation Committee annually reviews and determines the base salaries of our executives and evaluates the base salaries of new hires at the time of hire, as it did in fiscal year 2023 for Mr. Nargolwala in connection with his hiring. During fiscal year 2023, the Compensation Committee reviewed the base salaries of the NEOs, approving the adjustments shown in the table below, as applicable, for all NEOs other than Mr. D’Antilio who joined the Company in January 2022, and Mr. Nargolwala who joined the Company in June 2022, and whose base salaries were negotiated in connection with their hiring. In deciding whether to make any annual adjustments, the Compensation Committee considered factors, including each NEO’s performance, tenure, and job responsibilities, in addition to considering market information from our February 2022 competitive analysis. In recognition of his expanded role with the Company in becoming our first Chief Technology Officer, the Compensation Committee increased Mr. Doogue’s annual salary to $390,000 in September 2022.

1. Mr. Nargolwala joined the Company in June 2022.
2. Mr. D’Antilio joined the Company in January 2022.
3. Mr. Doogue’s salary was subsequently adjusted to $390,000 in September 2022 in connection with becoming SVP, Chief Technology Officer.
Fiscal Year 2023 AIP
Each of our NEOs participates in our AIP, which is focused on rewarding our executive officers for annual operating performance that meets or exceeds pre-established goals. The Compensation Committee periodically reviews and determines each NEO’s target bonus opportunity (expressed as a percentage of base salary) under the AIP. During fiscal year 2023, the Compensation Committee reviewed each NEO’s target bonus opportunity, approving the adjustment to Mr. Doogue’s target shown in the table below. The Compensation Committee considered the same factors as in its deliberations relating to base salaries, as well as our desire to motivate achievement of short-term financial objectives via meaningful annual incentive opportunities. Each NEO’s target bonus opportunity was generally aligned to the market 50th percentile, as detailed in the February 2022 competitive analysis.

Name | 2022 Target AIP (% of Base Salary) | 2023 Target AIP (% of Base Salary) | Increase (%) | Reason for Change
Vineet Nargolwala | n/a | 110.0 | % | — | % |
Derek P. D'Antilio | 75.0 | % | 75.0 | % | — | % |
Sharon S. Briansky | 70.0 | % | 70.0 | % | — | % |
Max R. Glover | 75.0 | % | 75.0 | % | — | % |

Former Officer |  |  |  |
Ravi Vig | 125.0 | % | 125.0 | % | — | % |

The actual amount of the annual bonuses paid under the AIP each year may be more or less than the applicable NEO’s target bonus opportunity, depending on Company performance against a set of pre-established performance metrics. For fiscal year

| INNOVATION WITH PURPOSE | 43

EXECUTIVE AND DIRECTOR COMPENSATION
2023, these Company performance metrics included Performance EBIT (weighted 70%) and revenue, as represented by year-over-year sales growth percentage (weighted 30%). The annual bonuses under the AIP are also subject to potential increase or reduction at the discretion of the Compensation Committee, based on individual NEO performance during the fiscal year (the “Multiplier for Individual Performance”).
The table below illustrates AIP determinations at various levels of performance and the actual performance in fiscal year 2023 for each metric. For performance between points referenced in the table, straight line interpolation is used for the determination of actual achievement of performance metrics.

| Performance Metric | Threshold | Target | Maximum | Actual Performance
Performance EBIT 1 | Performance Goals ($M) | $ | 200.0 |  | $ | 247.0 |  | $ | 270.0 |  | $ | 282.6 |

% Pool Funding | 80.0 | % | 100.0 | % | 200.0 | % | 200.0 | %

1. Actual performance for Performance EBIT for the period is calculated from GAAP operating income, as adjusted as provided in Appendix A.Target aip mix 70% 30% performance ebit revenue
In May 2023, the Compensation Committee assessed the Company’s fiscal year 2023 achievement of the corporate performance objectives. The sum of the Performance EBIT portion of the pool funding (70% weighting multiplied by the actual Performance EBIT financial performance of 200%) plus the revenue portion of the pool funding (30% weighting multiplied by the actual revenue financial performance of 200%) for fiscal year 2023 resulted in achievement at 200% of target. Additionally, the Compensation Committee did not choose to exercise upward or downward discretion based on individual performance for fiscal year 2023 AIP payout determinations, and so the Multiplier for Individual Performance for all NEOs was 1.0.
Per the terms of his Severance Agreement, the portion of Mr. Vig’s lump-sum payment attributable to his 2023 AIP award was funded at the projected annual bonus rate on his retirement date and prorated to reflect his partial service in fiscal year 2023. The projected annual bonus rate as of his retirement date was calculated to be $323,397.
The table below illustrates the final AIP payout determinations for each NEO.

Name | 2023 Target AIP ($) | Pool Funding per Corporate Achievement | Multiplier for Individual Performance | Final AIP Payout ($)

The AIP payments with respect to fiscal year 2023 detailed above were paid to each NEO on June 2, 2023.
Additional Bonus Awards in Fiscal Year 2023
Mr. Nargolwala received a $217,000 Signing Bonus in accordance with his Employment Agreement to incentivize him to join the Company. In the event that Mr. Nargolwala voluntarily resigns without Good Reason or the Company terminates his employment for Cause (as each such term is defined in the Employment Agreement) before July 1, 2023, Mr. Nargolwala will be required to repay the full Signing Bonus. In the event that Mr. Nargolwala voluntarily resigns without Good Reason or the Company terminates his employment for Cause between July 1, 2023 and July 1, 2024, Mr. Nargolwala will be required to

| INNOVATION WITH PURPOSE | 44

EXECUTIVE AND DIRECTOR COMPENSATION
repay a prorated amount of the Signing Bonus based upon the number of months worked during the two-year period ending on July 1, 2024.
Pursuant to her offer letter, Ms. Briansky received a cash payment of $250,000 upon her attainment of six months of service in June 2022 as the final installment of her deferred hiring bonus. If Ms. Briansky terminates her employment in less than two years from her date of hire, she will be required to make a prorated repayment of her entire hiring bonus based upon the number of months worked less than two years.
Mr. Glover received a cash payment of $49,500 in July 2022 as the final installment of his deferred hiring bonus pursuant to his offer letter, which was included as an inducement to join the Company in 2019.
Fiscal Year 2023 Equity Compensation
We use equity awards as a form of long-term incentive compensation to motivate and reward executive officers for effectively executing longer-term strategic and financial objectives. The multi-year vesting provisions of these awards also support the Company’s leadership retention strategy. The value of these equity awards is based on the value of our Common Stock, and these awards help align the interests of our executive officers with those of the Company’s shareholders.
In fiscal year 2023, our annual equity awards consisted of a combination of RSUs and PSUs. Further details regarding awards granted during fiscal year 2023 are set forth below. The Compensation Committee elected to use PSUs as the primary equity vehicle for annual equity awards to NEOs because these awards provide upside potential for superior performance, and decline in award size, potentially to zero, for performance that is below threshold level expectations.
For each eligible executive, the Committee considers the relative value of equity awards compared to the equity awards held by other executive officers, the desired incentive mix between PSU awards and RSU awards, a compensation analysis performed by Meridian, and the individual experience, skills and performance level of the executive officer to determine the size of equity awards.
Annual Equity Awards
The annual equity awards granted to each of our NEOs consisted of RSUs (40% of each award) and PSUs (60% of each award). The RSUs are scheduled to vest in four equal installments on each of May 16, 2023, 2024, 2025, and 2026, subject to continued employment through each vesting date. The PSUs vest based on achievement of three separate performance and service criteria, as outlined in the table below and described in greater detail following the table.

| Performance Metric | PSU Award Weighting (at target) | Performance Period | Additional Service-Based Vesting after Performance Period
Relative Total Shareholder Return (“Relative TSR”) | 50% | Three years (fiscal years 2023 through 2025) | Earned shares (if any) based on this metric vest on May 16, 2025
Strategic Products Revenue | 25% | One year (fiscal year 2023) | Earned portion of PSU shares (if any) based on this metric vest 50% on May 16, 2023, and 50% on May 16, 2024
Cumulative Performance EBITDA | 25% | One third allocated to each of one year (fiscal year 2023), two year (fiscal years 2023 and 2024) and three year (fiscal years 2023 through 2025) performance periods | Earned portion of PSU shares (if any) based on this metric vest on May 16, 2025

Psu award weighting (at target) 25% 50% 25% relative tsr strategic product revenue cumulative performance ebitda
The Relative TSR portion of the PSUs are earned based on our total shareholder return (“TSR”) performance, as measured relative to the performance of companies in the SOX Index over a three-year period (fiscal years 2023 through 2025). Target vesting at 100% of this portion of the award is achieved if the Company’s TSR equals the TSR of the median company in the SOX Index. The actual number of PSUs that will be earned can range from 0% - 200% of the target amount, with a threshold vest (fixed at 50% of the target number of PSUs for this portion of the award) achieved if the Company’s TSR equals the TSR of the 25th percentile SOX Index company, and a maximum vest (fixed at 200% of the target number of PSUs for this portion of the

award) achieved if the Company’s TSR equals the TSR of the 75th percentile SOX Index company. Straight line interpolation is used for vesting determinations for performance between threshold and target or between target and maximum. If the Company’s TSR is negative during the performance period, vesting is capped at target for this portion of the award, regardless of what the award formula would otherwise specify for this portion of the award.

Performance Metric |  | Threshold |  | Target |  | Maximum
Relative TSR - TSR percentile rank vs. SOX Index | Goal | <25th | 25th | 37.5th | 50th | 62.5th | 75th
Payout % (positive TSR) | —% | 50.0% | 75.0% | 100.0% | 150.0% | 200.0%
Payout % (negative TSR) | —% | 50.0% | 75.0% | 100.0% | 100.0% | 100.0%

The Strategic Products revenue portion of the PSUs are earned based on our revenue applicable to products that drove our growth in the e-Mobility and select industrial markets in fiscal year 2023 (the “Strategic Products”), as compared to pre-established threshold, target and maximum goals. The table below illustrates Strategic Products revenue PSU payout determinations at various levels of performance, including actual performance in fiscal year 2023, and the resulting payout (i.e., the percentage of target PSUs for this portion of the award that vested one half on May 16, 2023, with the remaining half to vest on May 16, 2024, subject to a recipient meeting the continued service requirement). For performance between points referenced in the table, straight line interpolation was used for PSU vesting determination.

Performance Metric | Threshold | Target | Maximum | Actual Performance
Strategic Products revenue FY23 ($ millions) | Goal ($ millions) | $ | 360.0 |  | $ | 400.0 |  | $ | 420.0 |  | $ | 477.1 |
Payout % | 50.0 | % | 100.0 | % | 200.0 | % | 200.0 | %

The cumulative non-GAAP adjusted EBITDA, further adjusted for the operational impact of acquisitions (“Performance EBITDA”) portion of the PSUs are earned based on cumulative Performance EBITDA, as compared to threshold, target and maximum goals for each of fiscal year 2023, the two-year period encompassing fiscal years 2023 and 2024, and the three-year period encompassing fiscal years 2023, 2024 and 2025. The table below illustrates cumulative Performance EBITDA PSU payout determinations for the one-third of cumulative Performance EBITDA PSUs allocated to fiscal year 2023 performance, and the resulting payout (i.e., the percentage of PSUs allocated to fiscal year 2023 performance that will vest on May 16, 2025, subject to a recipient meeting the continued service requirement) for this portion of the award. For performance between points referenced in the table, straight line interpolation was used for the PSU vesting determination.

Performance Metric | Threshold | Target | Maximum | Actual Performance 1
Fiscal Year 2023 Cumulative Performance EBITDA | Goal ($ millions) | $ | 243.8 |  | $ | 297.7 |  | $ | 319.0 |  | $ | 332.3 |
Payout % | 50.0 | % | 100.0 | % | 200.0 | % | 200.0 | %

1. Actual performance for cumulative Performance EBITDA for the period is calculated from GAAP net income, as adjusted as provided in Appendix A, with such number calculated above the baseline level of Performance EBITDA for fiscal 2022.
The table below illustrates how payouts for this portion of the award will be determined for each of (1) the two-year period encompassing fiscal years 2023 and 2024, and (2) the three-year period encompassing fiscal years 2023, 2024, and 2025.

Performance Metric | Threshold | Target | Maximum
Fiscal Years 2023-2024 Cumulative Performance EBITDA | Goal | 84.72% of Plan 1 | At Plan 1 | 106.77% of Plan 1
Payout % | 50.0% | 100.0% | 200.0%
Fiscal Years 2023-2025 Cumulative Performance EBITDA | Goal | 86.32% of Plan 1 | At Plan 1 | 106.3% of Plan 1

EXECUTIVE AND DIRECTOR COMPENSATION
Mr. Nargolwala’s Sign-On and Initial Equity Awards
In connection with and as inducement to Mr. Nargolwala’s joining the Company, Mr. Nargolwala was granted the one-time Sign-On Equity Award on June 13, 2022. The Sign-On Equity Award represented the number of shares of Common Stock having a grant date fair value of $4 million divided by the closing price of a share of the Company’s Common Stock on Nasdaq on the date of grant. The Sign-On Equity Award RSUs vested as to 60% of the underlying shares on the first anniversary of the grant date, and the remaining 40% of the underlying shares will vest on the second anniversary of the grant date, subject to Mr. Nargolwala’s continued employment with the Company through the vesting date.
Mr. Nargolwala was also granted the Initial Equity Award on August 1, 2022. The Initial Equity Award was designed to match the composition and terms of the annual equity award provided to each of the other NEOs. Accordingly, 40% of the Initial Equity Award was granted in the form of RSUs that will vest 25% per year over four years on the anniversary of the grant date, subject to Mr. Nargolwala’s continued employment with the Company through the vesting date, and the remaining 60% of the total Initial Equity Award was granted in the form of PSUs that vest based on achievement of performance goals and continued service over a three-year performance period. The design and weighting of each PSU metric was identical to the fiscal year 2023 grant made to the other NEOs. The Initial Equity Award represented the number of shares of Common Stock having a grant date fair value of $4 million divided by the closing price of a share of the Company’s Common Stock on Nasdaq on the date of grant.
Additional Retention Awards to Ms. Briansky and Messrs. D’Antilio, Glover and Doogue
In connection with the appointment of Mr. Nargolwala as our Chief Executive Officer, we granted retention awards of RSUs in June 2022 to Ms. Briansky, Mr. Glover, and Mr. Doogue and amended the vesting terms of Mr. Glover’s and Mr. Doogue’s outstanding RSU and PSU awards. In approving such one-time awards upon the amendment of vesting terms, the Compensation Committee considered the need to ensure management stability and continuity, as well as labor market conditions and competition for top talent during a time when our industry was ramping up production following COVID-19 related supply chain disruptions. Ms. Briansky’s RSUs had a grant date fair value of $400,000, and 75% of the award vested on June 3, 2023, with the remaining 25% of the award scheduled to vest on June 3, 2024, subject to Ms. Briansky’s continued employment with the Company through the vesting date. Mr. Glover’s and Mr. Doogue’s RSUs, each with a grant date fair value of $275,000, vested in full on June 3, 2023. The amendment to the terms of Mr. Glover’s and Mr. Doogue’s outstanding RSU and PSU awards provided these executives prorated accelerated vesting of the awards upon a termination of the employment for any reason after June 30, 2023.
On February 2, 2023, the Committee granted retention awards of RSUs to Ms. Briansky and Mr. D'Antilio to further align each of their interests with those of our shareholders, encourage retention, and recognize each individual’s importance to the Company and performance in the first year of service to the Company. The RSUs granted to Ms. Briansky and Mr. D’Antilio vest in full on February 13, 2026, subject to the NEO’s continued employment with the Company through the vesting date. Ms. Briansky’s RSUs had a grant date fair value of $750,000, and Mr. D’Antilio’s RSUs had a grant date fair value of $1,500,000.
Additional Award to Mr. Vig and Modification of Outstanding PSUs
Mr. Vig retired from the Company on June 13, 2022. Per the terms of his Severance Agreement, Mr. Vig was granted a one-time award of Substitute RSUs that vested on his retirement date covering a number of shares of the Company’s common stock equal to the product obtained by multiplying the number of shares of the Company’s Common Stock underlying his Forfeited Awards by the percentage achievement of the performance goals associated with such Forfeited Awards, assuming target satisfaction thereof or, if greater, generally based on the level of actual achievement of the performance goals, measured through the end of the most recent fiscal quarter.
Mr. Vig’s Severance Agreement also provided for the PSU Modification, in which all PSUs held by Mr. Vig at the time of his retirement remained outstanding and became non-forfeitable. The number of shares earned was based on the achievement of applicable performance conditions that were fixed as of the time of Mr. Vig’s retirement, and such shares will be delivered in four approximately semi-annual installments pursuant to the original vesting schedule, provided that in no event will the number of shares delivered to Mr. Vig following vesting have a fair market value on the date of delivery (the “Specified Value”) that is less than the number of earned shares multiplied by a designated stock price that is equal to the greater of the fair market value on the date of delivery, or the trailing 20-day average of the share price as of Mr. Vig’s retirement date (the “Specified Minimum Price”). Although no additional PSUs were issued as a result of the PSU Modification at the time of the modification, the PSU Modification could require the Company to deliver additional shares to Mr. Vig if the price of our Common Stock is below the Specified Minimum Price of $24.20; however, the closing price of our Common Stock on Nasdaq on each applicable

| INNOVATION WITH PURPOSE | 47

EXECUTIVE AND DIRECTOR COMPENSATION
vesting date since Mr. Vig’s retirement has been above the Specified Minimum Price, and accordingly, no additional shares have been delivered pursuant to the PSU Modification. The incremental compensation expense related to the PSU Modification has been included in the Stock Awards column for Mr. Vig in the Summary Compensation Table on page 53.
Equity Awards Granted in Fiscal 2023
The table below summarizes all the equity awards granted to our NEOs in fiscal year 2023.

1. The PSU Modification to 586,510 unvested PSUs held by Mr. Vig at the time of his retirement (including the aggregate 132,880 target PSUs detailed in the table that were granted in fiscal year 2023) is not reflected in the table above because no new PSUs or RSUs were issued with respect to the PSU Modification at the time it was made. The incremental compensation expense related to the PSU Modification has been included in the Stock Awards column for Mr. Vig in the Summary Compensation Table on page 53.
Benefits and Perquisites
We maintain broad-based benefits for all employees, and our NEOs are eligible to participate on the same basis as other U.S.-based full-time employees. The retirement plan, as well as our other benefits, are designed to be competitive in the labor market and to provide financial protection and security for employees and their families.
Health/Welfare Plans
We offer medical, dental, and vision insurance to our NEOs and pay a portion of the premiums for these benefits consistent with the arrangements for all of our other U.S.-based, full-time employees. We also provide our NEOs and other eligible employees, at our expense, with group life and accidental death and dismemberment insurance benefits; short-term and long-term disability insurance benefits; paid time off benefits; and other ancillary benefits (for example, an employee assistance program).
Charitable Contributions
Subject to certain limitations, we match charitable donations made by our U.S.-based employees, including our NEOs, to eligible charitable organizations, up to a $5,000 annual limit per employee.
Inventor Awards Program
Under our Inventor Awards Program, our employees, including our NEOs, 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.
Retirement Plan
We currently maintain a 401(k) retirement savings plan (the “401(k) Plan”) for our U.S.-based employees, including our NEOs, who satisfy certain eligibility requirements. Our NEOs are eligible to participate in the 401(k) Plan on the same terms as other full-time employees in the U.S. 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 or after-tax basis through contributions to the 401(k) Plan. During fiscal year 2023, we matched contributions made by participants in the 401(k) Plan up to five percent (5%)

| INNOVATION WITH PURPOSE | 48

EXECUTIVE AND DIRECTOR COMPENSATION
of the employee’s eligible compensation, up to the statutory eligible compensation limit, and these matching contributions were fully vested as of the date they were made.
Deferred Compensation Plan
We maintain an Executive Deferred Compensation Plan (the “DCP”) under which eligible employees, including our NEOs, are permitted to defer up to 90% of their base salary and/or up to 100% of any amount earned under the AIP. All deferrals are fully vested as of the date the deferral is made. During fiscal year 2023, we also made fully vested employer contributions to our NEOs’ (and other participants’) DCP accounts. The amounts of this contribution were designed to replace matching contributions to our 401(k) Plan for eligible wages paid over the applicable statutory limits and are capped at five percent (5%) of the participant’s annual eligible compensation that exceeds the statutory limit. Amounts deferred under the DCP may be notionally invested by participants in one or more of the investment choices offered in the DCP, many of which are the same investments offered in the 401(k) Plan and are subject to adjustment for earnings or losses resulting from these investments. DCP 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).
No Perquisites or Tax “Gross Ups”
We do not currently provide material perquisites to our NEOs, and we do not view perquisites or other personal benefits as a significant component of our executive compensation program. In the future, we may provide perquisites or other personal benefits in limited circumstances, such as where we believe it is appropriate to assist an individual executive officer in the performance of the executive’s duties, to make our executive officers more efficient and effective, and for recruitment, motivation, or retention purposes. All future practices with respect to perquisites or other personal benefits will be approved by the Compensation Committee.
We do not provide tax “gross ups” to our named executive officers.
Compensation Policies
Prohibition on Option Re-Pricing and Backdating
We currently have no outstanding stock option awards, but if we choose to grant stock options in the future, options to purchase shares of our Common Stock will be granted with an exercise price equal to the closing market price of our Common Stock on Nasdaq on the effective date of grant. The 2020 Plan prohibits re-pricing of equity awards without shareholder approval, except in connection with certain corporate transactions involving the Company (including, without limitation, any stock dividend, distribution, stock split, extraordinary cash dividend, recapitalization, change in control, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase or exchange of shares of Company stock or other securities, or similar transactions).
Compensation Recovery
Under the Sarbanes-Oxley Act, in the event of misconduct that results in a financial restatement that would have reduced a previously paid incentive amount, we can recoup those improper payments from our CEO and CFO. In addition, our 2020 Plan provides for potential recoupment of incentive awards in certain circumstances in the event of a material financial restatement due to material noncompliance with financial reporting requirements or breach of restrictive covenants, if determined by the Compensation Committee.
In October 2022, the SEC adopted finalized rules implementing the clawback provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”), which required further rulemaking by Nasdaq to finalize its listing standards. The final listing standards filed by Nasdaq were approved by the SEC on June 9, 2023 and will be effective on October 2, 2023, requiring listed companies to adopt a compliant policy by December 1, 2023. We will adopt a Compensation Recovery Policy to comply with the new Nasdaq listing standards regarding clawback policies prior to December 1, 2023.
Anti-Hedging and Anti-Pledging Policies
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

| INNOVATION WITH PURPOSE | 49

EXECUTIVE AND DIRECTOR COMPENSATION
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 shareholders. In addition, our Insider Trading Compliance Policy provides that no Covered Person may pledge Company securities as collateral to secure loans. This prohibition means, among other things, that these individuals may not hold Company securities in a “margin” account, which would allow the individual to borrow against their holdings to buy securities.
Stock Ownership Guidelines
The Company has robust stock ownership guidelines for directors and officers that require each non-employee director who receives compensation from the Company for their Board services (“Covered Directors”) and senior officers and certain other senior employees of the Company (“Covered Executives”) to own shares of our Common Stock. Our stock ownership guidelines are limited to Covered Directors because some non-employee directors serve as appointees of shareholders under the Stockholders Agreement and do not receive any shares of Common Stock or other compensation for their service on the Board. See the “2023 Director Compensation” section of this proxy statement for additional information regarding Board compensation.
Under the guidelines, all current Covered Directors and Covered Executives, including each of our NEOs, must own shares of our Common Stock with a value equal to a certain multiple of their annual Board retainer, in the case of Covered Directors, or base salary, in the case of Covered Executives. Please refer to the table below for the applicable multiple for our Covered Directors, CEO and other Covered Executives. Equity interests that count towards the satisfaction of the ownership guidelines include unvested time-based RSUs, and vested shares, including shares owned outright, shares jointly owned, shares owned in retirement accounts, and shares owned in trust or other estate planning vehicles for the benefit of a Covered Director or Covered Executive’s immediate family members. Unearned performance awards and unexercised stock options, if we were to issue stock options, do not count towards the ownership guidelines. Covered Directors and Covered Executives have four years from the date of the Company’s IPO or, if later, the date they first become a member of the Board or an officer to meet the ownership levels. For purposes of these guidelines, shares are valued based upon the then-current market value, or if higher, the value on the date of acquisition. Based on an evaluation on the Record Date, all of our NEOs employed at the end of fiscal year 2023 and all Covered Directors were either in compliance with our stock ownership guidelines or are expected to be in compliance within this time window.

| Covered Person | Multiple of Base Salary / Board Retainer |
Covered Director | 3x |
Chief Executive Officer | 6x |
Other Covered Executives | 3x |

Compensation Risk Assessment
Our Compensation Committee has reviewed our incentive compensation programs, discussed the concept of risk as it relates to our compensation program, considered various mitigating factors, and reviewed these items with its independent compensation consultant, Meridian. In addition, our Compensation Committee asked Meridian to conduct an independent risk assessment of our executive compensation program. Based on these reviews and discussions, the Compensation Committee does not believe our compensation program creates risks that are reasonably likely to have a material adverse effect on our business.
Tax and Accounting Considerations
Section 162(m) of the Code generally limits the amount of remuneration that the Company may deduct in any calendar year for certain executive officers to $1 million. While the Compensation Committee will continue to consider the deductibility of compensation as a factor in making compensation decisions, it retains the flexibility to provide compensation that is consistent with the Company’s goals for its executive compensation program, even if such compensation would not be fully tax-deductible.
“Golden Parachute” Payments
Sections 280G and 4999 of the Code provide that certain executive officers and other service providers who are highly compensated or hold significant equity interests may be subject to an excise tax if they receive payments or benefits in connection with a change in control of the Company that exceeds certain prescribed limits, and that we, or a successor, may

| INNOVATION WITH PURPOSE | 50

EXECUTIVE AND DIRECTOR COMPENSATION
forfeit a deduction on the amounts subject to this additional tax. We do not provide any tax gross ups to cover excise taxes under Section 4999 in connection with a change in control. Mr. Nargolwala’s Employment Agreement contains a provision that provides that in the event that any payment or benefit received or to be received by Mr. Nargolwala in connection with a change in control would be subject to the excise tax imposed under Section 4999 of the Code, then such payments will be reduced if and to the extent that doing so will result in net after-tax payments and benefits for Mr. Nargolwala that are more favorable than the net after-tax payments and benefits payable to Mr. Nargolwala in the absence of such a reduction after the imposition of the excise tax. For additional details, see page 60.
Accounting for Share-Based Compensation
We follow Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 718 for all stock-based awards. ASC Topic 718 requires companies to measure the compensation expense for all share-based payment awards made to employees and directors, including stock options and full value stock awards, based on the aggregate estimated grant date fair value of these awards. This calculation is performed for accounting purposes and reported in the compensation tables on pages 53 - 55 and page 62 of this proxy statement. ASC Topic 718 also requires companies to recognize the compensation cost of their stock-based compensation awards in their income statements over the period that an executive officer is required to render service in exchange for the option or other award.

1.Reflects salary paid during the fiscal year. Fiscal year 2023 was a 53-week year, while fiscal years 2022 and 2021 were 52-week fiscal years.
2.For Messrs. Nargolwala and D’Antilio, amount shown represents a signing bonus paid pursuant to their employment agreement and offer letter, respectively, in connection with the NEO joining the Company. For Ms. Briansky and Mr. Glover, amounts shown represent deferred signing bonuses made pursuant to their offer letters. All bonus payments are subject to recoupment by the Company if the NEO voluntary terminates employment prior to the requisite service period specified in the NEO’s offer letter or employment agreement, as applicable, and in the case of Mr. Nargolwala, if his voluntary termination is not for Good Reason (as defined in his Employment Agreement). Mr. Glover’s recoupment period ended in June 2022.
3.Amounts shown represent the aggregate grant date fair value of RSU and PSU awards, made during fiscal 2023, 2022 and 2021, respectively, calculated in accordance with FASB ASC Topic 718. For information on the valuation assumptions with respect to these awards, refer to note 18 of the Allegro MicroSystems, Inc. financial statements that were included in our Annual Report on Form 10-K for the fiscal year ended March 31, 2023. Awards that are subject to Company financial performance metrics are accounted for as performance-based awards and are shown at 100% of the target award level, which was determined to be the probable outcome for such awards. If these performance-based awards were shown at their maximum attainment level, then the aggregate grant date fair values shown in the table above for fiscal 2023 for all Stock Awards would be as follows: Mr. Nargolwala: $9,565,143; Mr. D’Antilio: $3,574,474; Ms. Briansky: $2,533,022; Mr. Glover: $2,211,148; Mr. Doogue: $2,072,821 and Mr. Vig: $17,590,898.

Potential Payments upon Termination or Change in Control
Overview
The information provided in the following tables reflects the amount of incremental compensation required to be paid to each applicable NEO in the event of a change in control of the Company, or a termination of the NEO’s employment. For purposes of the disclosure, we have assumed that all triggering event(s) took place on March 31, 2023, and we used the closing price per share on Nasdaq of our Common Stock on March 31, 2023 ($47.99). Due to the number of factors that affect the nature and amount of benefits provided upon the occurrence of such events, actual amounts paid or distributed may be different from the amounts disclosed below. Factors that could affect the actual amounts paid include:
•when the event actually occurs;
•the number of outstanding but unvested stock awards then held by the NEO;
•awards granted after March 31, 2023;
•the Company’s Relative TSR over a specified period and its performance against certain financial and/or business objectives established for determining the level of payment and/or vesting of outstanding, but unvested, stock awards; and

| INNOVATION WITH PURPOSE | 58

EXECUTIVE AND DIRECTOR COMPENSATION
•the Company’s stock price as of the date of such event.
Specifically excluded from the information and tables below are any amounts which are not contingent upon the occurrence of the triggering event(s) or payments pursuant to Company benefit plans that are generally available to all U.S. salaried employees of the Company and do not discriminate in scope or terms of operation in favor of our NEOs (e.g., term life insurance, long-term disability insurance, etc.).
The payments and benefits Mr. Vig actually received in connection with his separation from the Company is set forth in the Summary Compensation Table on page 53 and is described in the section entitled “Compensation Discussion and Analysis - CEO Transition in Fiscal Year 2023 - Retirement of Mr. Vig” on page 37. Amounts for Mr. Vig are not included in the tables below since he left the Company prior to the end of fiscal year 2023.
Severance and Employment Agreements
We entered into severance agreements with each of Messrs. Doogue and Glover on October 3, 2017 and October 1, 2019, respectively (together, the “Severance Agreements”). On September 30, 2020, the Company amended and restated these Severance Agreements.
We entered into severance agreements with Ms. Briansky (the “Briansky Severance Agreement”) and Mr. D’Antilio (the “D’Antilio Severance Agreement”) in connection with their hiring o n December 6, 2021 and J anuary 10, 2022, respectively. Both the Briansky Severance Agreement and the D’Antilio Severance Agreement were amended on May 15, 2023 to remove a tax gross up provision related to post-employment healthcare coverage. Mr. Nargolwala’s severance provisions are described in the Employment Agreement as of his hire on June 13, 2022.
The Severance Agreements (as amended and restated), the Briansky and D’Antilio Severance Agreements, and the Employment Agreement provide that if a NEO’s employment is terminated by the Company without “cause” or by the executive for “good reason” (each such term as defined in the applicable agreement) (a “Qualifying Termination”), subject to the executive’s execution of an effective general release of claims and continued compliance with applicable non-competition, non-solicitation and (in the cases of Messrs. Doogue and Glover) other restrictive covenants applicable to the executive pursuant to their respective pre-IPO share award agreement, we will pay or provide the executive with the following severance benefits:

Benefit upon Qualifying Termination under applicable NEO agreement | Vineet Nargolwala | Derek P. D’Antilio | Sharon S. Briansky / Max R. Glover / Michael C. Doogue
Cash Severance 1 | Lump sum cash payment equal to 3.0 times his then-current base salary (2.0 times if such termination occurs after June 30, 2023) | Lump sum cash payment equal to 2.0 times his then- current base salary and target bonus | Lump sum cash payment equal to 1.0 times the NEO’s then-current base salary and target bonus
Prorated Bonus 1 | Cash payment equal to the amount of 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
Treatment of RSU Awards | Accelerated vesting of outstanding RSU awards with respect to the number of shares that would have become vested on the next applicable vesting date following such Qualifying Termination | Any then-outstanding incentive equity awards (then-held by the NEO) will be governed by the applicable equity incentive plan or award agreement
Treatment of PSU Awards | Prorated vesting of outstanding PSU awards, with the applicable performance conditions being deemed achieved at the greater of the target performance level or the trending performance level, as determined by the Compensation Committee | Any then-outstanding incentive equity awards (then-held by the NEO) will be governed by the applicable equity incentive plan or award agreement
Continued Company-paid Health Care Coverage 2 | For up to 12 months following termination | For up to 24 months following termination | For up to 18 months following termination

| INNOVATION WITH PURPOSE | 59

EXECUTIVE AND DIRECTOR COMPENSATION
1.Subject to applicable withholding and for delays in distribution that may be required to comply with tax regulations related to deferred compensation, the cash severance benefit and prorated bonus will be paid in a lump-sum payment within fifteen days following termination for each NEO, with the exception of Mr. Nargolwala, whose payments are required to be made on the first regular payroll date following the date his general release of claims becomes effective and irrevocable.
2.Mr. D’Antilio’s and Ms. Briansky’s agreements also provided that, to the extent such Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, continuation would result in the imposition of income taxes on Mr. D’Antilio or Ms. Briansky, an additional monthly payment would be made to Mr. D’Antilio or Ms. Briansky to cover the amount of any such taxes for up to 18 months following the date of such termination. Each of their agreements were revised in May 2023 to remove this benefit.

Our NEOs 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 “Severance and Employment Agreements.” In addition, upon a Qualifying Termination outside of a 12-month period following a change in control of our Company, or a termination due to death or disability, an executive’s RSUs which are eligible to vest on the next vesting date following such termination will vest, and a prorated portion of such executive’s PSUs would vest as of the date of such termination, with the applicable performance conditions being deemed achieved at the greater of the target performance level or the trending performance level at the time of termination, as determined by the Compensation Committee for awards granted to the NEOs on or after May 2022. For PSU awards granted prior to May 2022, performance is measured based on actual performance at the end of the performance period, and the PSUs do not vest until after the completion of the performance period. PSUs granted prior to May 2022 were subsequently amended in April 2023 to align the treatment of vesting and fulfillment of performance conditions with awards granted on or after May 2022.
Potential Payments upon Termination or a Change in Control
Under the terms of his Employment Agreement, if Mr. Nargolwala is terminated in a Qualifying Termination within 24 months of a Change in Control, he would receive all of the same benefits listed in the table in the “Severance and Employment Agreements” section above, except his lump sum cash severance amount would be equal to his multiplier times his annual base salary plus target bonus, and all of his equity would be treated in accordance with the following paragraph.
In addition, under the terms of the 2020 Plan, if an NEO has a Qualifying Termination within 12 months following a change in control of the Company, all outstanding equity incentive awards held by such executive under the 2020 Plan will vest, with the award agreement for outstanding PSUs specifying that performance for these awards shall be measured based on the greater of target or actual performance. “Cause” is defined under the 2020 Plan as the definition given to such term in a NEO’s severance or employment agreement.
Section 280G of the Code
The D’Antilio Severance Agreement and the Briansky Severance Agreement each provide that in the event that the cash severance and prorated bonus benefits set forth in the table in the “Severance and Employment Agreements” section above, the health care continuation coverage benefit, and/or any other any payment, coverage or benefit, including any accelerated vesting of Company equity compensation, provided in respect of Mr. D’Antilio’s or Ms. Briansky’s employment or termination of employment would constitute “parachute payments” within the meaning of Section 280G(b)(2) of the Code or would subject Mr. D’Antilio or Ms. Briansky to an excise tax under Section 4999 of the Code, then, provided that the requirements of Treas. Reg. Section 1.280G-1 Q&A-6(a)(2)(i) are met, the Company shall use its reasonable best efforts to obtain shareholder approval with respect to such parachute payments pursuant to Section 280G(b)(5)(B) of the Code, subject to Mr. D’Antilio’s or Ms. Briansky’s execution of a contingent waiver of his/her receipt of, or entitlement to retain, any such parachute payments, to the extent necessary to obtain such shareholder approval.
Mr. Nargolwala’s Employment Agreement contains a provision that provides that in the event that any payment or benefit received or to be received by Mr. Nargolwala, including the benefits set forth in the “Severance and Employment Agreements” section above, would be subject to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”), then the total payments due to Mr. Nargolwala shall be reduced to the extent necessary to ensure that no portion of the total payments are subject to the Excise Tax, but only if (i) the net amount of the total payments, as so reduced is greater than or equal to (ii) the net amount of the total payments without a reduction, in each case after taking into account the net amount of certain taxes and the phase out of itemized deductions and personal exemptions attributable to potential payments.

5. We determined that Performance EBIT in our compensation plans, to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEOs and Non-PEO NEOs in 2023. This performance measure may not have been the most important financial performance measure for fiscal 2022 and 2021, and we may determine a different financial performance measure to be the most important financial performance measure in future years. Performance EBIT is a non-GAAP financial measure explained in Appendix A of this proxy statement.

CEO Pay Ratio
As required by Section 953(b) of the Dodd-Frank Act and Item 402(u) of Regulation S-K, we are required to disclose the ratio of our CEO’s annual total compensation to the annual total compensation of our other employees.
The total compensation for 2023 to our CEO as of the end of our 2023 fiscal year, using the same methodology as was used to calculate the amounts in the Summary Compensation Table on page 53, but annualized and adjusted as described below, was $10,599,315. The annual total compensation for fiscal year 2023 for our median-compensated employee, who is located in the Philippines, and identified as discussed below, was $10,702, as calculated in accordance with the rules applicable to the Summary Compensation Table. Based on this information, for fiscal year 2023, the ratio of the annual total compensation of our CEO to the total annual compensation of our median-compensated employee was approximately 990 to 1.
Methodology, Assumptions, and Estimates Used in Determining our Pay Ratio Disclosure
We chose December 31, 2022 as the date for establishing the employee population used in identifying the median-compensated employee and used fiscal year 2023 as the measurement period. Similarly, we chose December 31, 2022 to identify the CEO in service on that date, and annualized CEO total compensation as if he had been CEO for the entirety of fiscal year 2023. Mr. Nargolwala’s annualized total compensation was determined by making the following adjustments:

Summary Compensation Table Component | Actual Values from Summary Compensation Table |  | Annualized and One-Time Values Used to Calculate CEO Pay Ratio |  | Description of Adjustment
Salary | $ | 484,615 |  |  | $ | 600,000 |  |  | Annualized
Bonus | $ | 217,000 |  |  | $ | 217,000 |  |  | Not annualized; one-time payment at sign-on
Stock Awards | $ | 8,365,115 |  |  | $ | 8,365,115 |  |  | Not annualized; Initial Equity Award and Sign-On Equity Award included
Non-Equity Incentive Plan Compensation | $ | 1,052,384 |  |  | $ | 1,320,000 |  |  | Annualized for AIP payout based on target of 110% of full year salary
All Other Compensation | $ | 9,400 |  |  | $ | 97,200 |  |  | Annualized: employer HSA contribution, 401(k) matching contributions and employer contributions to the Nonqualified Deferred Compensation Plan
Total CEO Pay | $ | 10,128,514 |  |  | $ | 10,599,315 |  |  |

We identified the median-compensated employee using the consistently applied compensation measure of annualized base pay in U.S. dollars for each employee employed as of December 31, 2022. We annualized the compensation measure for permanent employees who joined in 2022. We captured all full-time, part-time, seasonal and temporary employees, consisting of approximately 4,525 individuals.
The annual total compensation of the median-compensated employee and the annual total compensation of the CEO were calculated in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K.

| INNOVATION WITH PURPOSE | 68

EXECUTIVE AND DIRECTOR COMPENSATION
The pay ratio reported above is an estimate calculated in a manner consistent with SEC rules based on our internal records and the methodology described above. Because the SEC rules for identifying the median-compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, apply certain exclusions, and make reasonable estimates and assumptions that reflect their employee populations and compensation practices, the pay ratio reported above should not be used as a basis for comparison between companies. In addition, we expect the Company’s annually reported pay ratio may vary significantly year over year, given the size of the Company and the potential variability in Company employee compensation.

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) shareholders who beneficially owned more than 5% of the outstanding shares of our Common Stock, and (ii) each of our directors, each of our NEOs and all current directors and executive officers as a group as of June 8, 2023, unless otherwise indicated.
The number of shares beneficially owned by each shareholder 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 8, 2023 is computed on the basis of 192,208,584 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 8, 2023, 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 shareholders listed below has sole voting and investment power with respect to the shares beneficially owned by the shareholder unless noted otherwise, subject to community property laws where applicable.

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS
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 that 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 that were entered into during the fiscal year ended March 31, 2023 were approved in accordance with our related person transaction policy. Transactions described below from before our IPO were entered into prior to 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 entitled “Executive and Director Compensation,” the following is a description of each transaction or agreement since March 26, 2022 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 2023 Annual Report.
Related Party Agreements
Wafer Foundry Agreement
In April 2013, Allegro MicroSystems, LLC, our wholly owned subsidiary (“AML”), entered into a semiconductor wafer foundry agreement with Polar Semiconductor, LLC (“PSL”) (as amended, the “Wafer Foundry Agreement”). Under the Wafer Foundry Agreement, PSL produced wafers for sale to AML in response to purchase orders AML submitted on a weekly basis. Purchase orders under the Wafer Foundry Agreement were binding, provided that AML could cancel any such order subject to paying the applicable termination charges as set forth in the Wafer Foundry Agreement. Wafer and mask pricing was 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 granted 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 fabrication facility.
The Wafer Foundry Agreement provided 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 could not exceed a specified de minimis amount.
As part of the transaction in which we divested a majority of our ownership interest in PSL to Sanken (the “PSL Divestiture”), 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 did 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 would be required to pay to PSL, within 60 days following the end of the applicable fiscal year, a

| INNOVATION WITH PURPOSE | 72

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS
“shortfall amount” equal to the fixed direct cost per production wafer multiplied by the difference between the actual number of production wafers purchased by AML and the Minimum Purchase Quantity. The Wafer Foundry Agreement, as amended, had an initial term of three years. Effective January 26, 2023, AML and PSL entered into a new Wafer Foundry Agreement for the fabrication of wafers (the “New Agreement”). The New Agreement replaced the Wafer Foundry Agreement with PSL, which was due to expire on March 31, 2023. The New Agreement has a three-year term, and auto renews for subsequent one-year terms, unless terminated by either party providing two years notice. Pursuant to the New Agreement, the Company will provide a rolling annual forecast for three years, the first two years of which will be binding. If the Company fails to purchase the forecasted number of wafers for either of the first two years, it will pay a penalty for any shortfall for the given year. The parties also agreed upon production lead-times, as well as wafer, alignment, and mask pricing for the first two years of the term. Any changes to such pricing are subject to mutual agreement. During the fiscal year ended March 31, 2023, AML made aggregate purchases of approximately $58.1 million from PSL pursuant to the Wafer Foundry Agreement and the New Agreement.
Notes Receivable from PSL
On December 2, 2021, AML entered into a loan agreement with PSL wherein PSL provided an initial promissory note to AML for a principal amount of $7.5 million (the “Initial PSL Loan”). The Initial PSL Loan will be repaid in equal installments, comprising of principal and interest accrued at 1.26% per annum, over a term of four years with payments due on the first day of each calendar year quarter (April 1st, July 1st, October 1st, and January 1st). On July 1, 2022, PSL borrowed an additional $7.5 million under the same terms of the PSL Loan (the “Secondary PSL Loan” and, together with the Initial PSL Loan, the “PSL Promissory Notes”). The loan funds were used by PSL to procure a deep ultraviolet scanner and other associated manufacturing tools necessary to increase wafer fabrication capacity in support of the Company’s increasing wafer demand. As of March 31, 2023, the outstanding balance of the PSL Promissory Notes was approximately $12.2 million. During the year ended March 31, 2023, PSL made quarterly payments to AML totaling approximately $3.0 million, which included approximately $0.2 of interest income.
Proposed Investment in PSL
On January 26, 2023, the Company announced that PSL is expected to receive a $150 million equity investment from an affiliate of OEP to expand 200 millimeter sensor and high voltage power wafer capacity at its fabrication facility in Bloomington, Minnesota. The terms and structure of this transaction have not been finalized, but if this transaction is completed under the proposed terms, the Company’s ownership position in PSL would be reduced.
Distribution of Allegro Products in Japan
In July 2007, we entered into a distribution agreement with Sanken (the “Japan Distribution Agreement”) pursuant to which we appointed Sanken to act as the exclusive distributor of our products in Japan (subject to certain exceptions for any products we and Sanken agree to exclude). The price Sanken was required to pay for our products under the Japan Distribution Agreement was set as a percentage of the selling price of such products to Sanken’s end customers. In addition, Sanken was 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 Japan Distribution Agreement was scheduled to expire on March 31, 2025. During the fiscal year ended March 31, 2023, Sanken purchased $160.8 million of products from us under this agreement.
On March 30, 2023, the Company entered into a termination of the distribution agreement with Sanken (the “Termination Agreement”). The Termination Agreement formally terminated the Japan Distribution Agreement, effective March 31, 2023. In connection with the termination of the Japan Distribution Agreement, and, as provided for in the Termination Agreement, the Company made a one-time payment of $5 million to Sanken in exchange for the cancellation of Sanken’s exclusive distribution rights in Japan. Concurrent with the Termination Agreement, AML and Sanken also entered into a short-term, nonexclusive distribution agreement (the “Short-Term Distribution Agreement”) and a consulting agreement (the “Consulting Agreement”), each of which were effective April 1, 2023. In addition, the Company allowed a one-time sales return from Sanken of resalable inventory of $4.2 million. The Short-Term Distribution Agreement provides for the management and sale of Company product inventory for a period of 24 months from April 1, 2023. Under the terms of the Consulting Agreement, Sanken agreed to continue to provide transition services for a period of six months from April 1, 2023 to a strategic customer as orders for the customer are transitioned from Sanken to the Company, and the Company agreed to pay Sanken for providing these transition services. No payments were made by the Company to Sanken under the Short-Term Distribution Agreement or the Consulting Agreement in the fiscal year ended March 31, 2023.
Transactions Involving Sanken
The Company sells products to, and purchases in-process products from Sanken. Net sales of the Company’s products to Sanken totaled approximately $160.8 million during the fiscal year ended March 31, 2023. Trade accounts receivables, net of

| INNOVATION WITH PURPOSE | 73

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS
allowances from Sanken totaled approximately $13.3 million as of March 31, 2023. Other accounts receivable from Sanken totaled approximately $0.2 million as of March 31, 2023.
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 the agreement can be terminated by either party upon providing six months’ notice. We made aggregate payments of approximately $0.3 million to Sanken under the sublease agreement during the fiscal year ended March 31, 2023.
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 CEO. 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 was terminated by the Board, effective November 10, 2022. The Consulting Agreement, as amended, provided for the following 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 provided that if Dr. Kazerounian’s consulting relationship was terminated by the Board, then he would be entitled to a termination payment in the amount of $180,000. In addition, the Consulting Agreement contained customary confidentiality and non-disclosure restrictions, an assignment of inventions provision and employee non-solicitation and non-competition restrictions, each of which were 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 31, 2023, we paid aggregate fees of approximately $318,125 to Dr. Kazerounian pursuant to the Consulting Agreement, including the termination payment of $180,000.
Stockholders Agreement

Mr. Hatano served as Manager of Business Performance for the Company from January 2006 to December 2022. During fiscal year 2023, he received compensation, consisting of salary, benefits and reimbursement of living expenses of approximately $148,000 from the Company. This amount was partially reimbursed to the Company by Sanken.

APPENDIX A
Non-GAAP Financial Measures
In addition to the measures presented in our consolidated financial statements, we regularly review other measures, 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 measures 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 and non-GAAP Basic and Diluted Earnings per Share, EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin, Performance EBIT, and Performance EBITDA (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;
•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 being adjusted 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.

APPENDIX A
Non-GAAP Gross Profit and Non-GAAP Gross Margin
We calculate non-GAAP Gross Profit and non-GAAP Gross Margin as GAAP Gross Profit and Gross Margin excluding the effects of certain restructuring costs, acquisition and related integration expenses, amortization of acquired intangible assets, stock-based compensation and other non-operational costs such as the impact of COVID-19 on operations. We calculate non-GAAP Gross Margin as non-GAAP Gross Profit divided by total net sales.
EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin, Performance EBITDA and Performance EBIT
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 effects of certain restructuring costs, acquisition and related integration expenses, amortization of acquired intangible assets, stock-based compensation and other non-operational costs, such as the impact of COVID-19, on total operating expenses as well as other income (expenses). We calculate Adjusted EBITDA Margin as Adjusted EBITDA divided by total net sales.
We calculate Performance EBITDA as Adjusted EBITDA adjusted for the impact of acquisitions and one-time contract costs occurring during the period. This includes the reversal of the net income impact of an acquisition, adjusted for amortization already identified within Adjusted EBITDA.
We calculate Performance EBIT as Non-GAAP Operating Income adjusted for the impact of acquisitions and one-time contract costs occurring during the period. We calculate Non-GAAP Operating Income as GAAP Operating Income excluding the effects of certain restructuring costs, acquisition and related integration expenses, amortization of acquired intangible assets, stock-based compensation and other non-operational costs, such as the impact of COVID-19.
Non-GAAP Net Income and Non-GAAP Diluted Earnings per Share
We calculate non-GAAP Net Income as Net Income excluding the effects of certain restructuring costs, acquisition and related integration expenses, amortization of acquired intangible assets, stock-based compensation and other non-operational costs, such as the impact of COVID-19, on total operating expenses as well as other income (expenses). We calculated non-GAAP Diluted Earnings per Share as non-GAAP Net Income divided by Diluted Weighted Average Shares Outstanding.
