Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On February 29, 2024, pursuant to the Amended and Restated Stockholders Agreement by and among Allegro MicroSystems, Inc. (the “Company”), OEP SKNA, L.P. (“OEP”), and Sanken Electric Co., Ltd., dated as of June 16, 2022 (the “Stockholders Agreement”), and as a result of OEP ceasing to beneficially own at least 5% of the outstanding shares of common stock of the Company, David Aldrich, Andrew Dunn, Susan Lynch, Joseph Martin, Mary Puma and Paul Carl (Chip) Schorr IV tendered their resignations from the Board of Directors (the “Board”) of the Company and all Board committees on which they served, with such resignations effective at 9:00 am EST on March 4, 2024. Such resignations were tendered in accordance with the terms of the Stockholders Agreement and were not the result of any disagreement with the Company or its management on any matter relating to the Company’s operations, policies or practices.

On March 4, 2024, at the recommendation of the Nominating and Corporate Governance Committee of the Board, the Board re-appointed: (i) Joseph Martin and Mary Puma as Class I directors; (ii) David Aldrich and Paul Carl (Chip) Schorr IV as Class II directors; and (iii) Andrew Dunn and Susan Lynch as Class III directors. Further, the Board re-appointed: (i) David Aldrich to serve on its Audit Committee and Nominating and Corporate Governance Committee; (ii) Andrew Dunn to serve on its Research & Development and Strategy Committee; (iii) Susan Lynch to serve on its Audit Committee; (iv) Joseph Martin to serve as Chairperson of its Audit Committee and to serve on its Research & Development and Strategy Committee; (v) Mary Puma to serve on its Compensation Committee; and (vi) Paul Carl (Chip) Schorr IV to serve as Chairperson of its Compensation Committee and to serve on its Nominating and Corporate Governance Committee. At the recommendation of the Nominating and Corporate Governance Committee, the Board also appointed: (i) Joseph Martin to serve on its Nominating and Corporate Governance Committee and (ii) Mary Puma to serve as Chairperson of its Research & Development and Strategy Committee. All of the foregoing appointments were effective at 9:01 am EST on March 4, 2024.

For purposes of service on the Board’s Audit Committee, the Nominating and Corporate Governance Committee has determined and recommended to the Board, and the Board has determined that David Aldrich, Susan Lynch and Joseph Martin each qualify as an independent director pursuant to Rule 10A-3 under the Securities Exchange Act of 1934, as amended, and the rules of the Nasdaq Stock Market. The Board has also determined that each of David Aldrich, Susan Lynch and Joseph Martin qualify as an “audit committee financial expert” as defined by the applicable Securities and Exchange Commission regulations.

The Company’s existing indemnification agreements with each of David Aldrich, Andrew Dunn, Susan Lynch, Joseph Martin, Mary Puma and Paul Carl (Chip) Schorr IV will continue to remain in effect. The unvested restricted stock units held by each of David Aldrich, Susan Lynch, Joseph Martin, Mary Puma and Paul Carl (Chip) Schorr IV that were previously awarded by the Company were not forfeited in connection with their resignations and re-appointments and are scheduled to vest at the Company’s next annual meeting of stockholders.
