On February 16, 2023, Thomas C. Teebagy, Jr. informed Allegro MicroSystems, Inc. (the "Company") that he will retire from the Company, effective June 2, 2023 (the "Retirement Date") and resign from his position as Senior Vice President of Operations and Quality, effective March 6, 2023. In connection with his retirement, the Company and Mr. Teebagy entered into a Retirement Separation Letter Agreement (the "Letter Agreement") dated February 16, 2023, pursuant to which Mr. Teebagy agreed to remain employed with the Company through the Retirement Date to ensure a smooth and orderly transition of responsibilities. In addition to the payment of any accrued and unpaid obligations, under the terms of the Letter Agreement, if Mr. Teebagy remains employed through the Retirement Date and executes a standard release of claims, he will be eligible to: (i) continue to participate in the Company's health plan coverages based on his elections on the Retirement Date at the same rates as active employees for the 12-month period beginning on the Retirement Date; (ii) receive a new grant of time-based restricted stock units ("RSUs") that vests as to the underlying shares in full on the Retirement Date, with the amount of such RSUs determined by calculating the prorated number of all unvested RSUs and performance-based restricted stock units ("PSUs") held by Mr. Teebagy that will otherwise be forfeited in full on the Retirement Date, with the end of the prorated period determined based on the one-year anniversary of the Retirement Date; and (iii) receive a one-time cash retention bonus in the amount of $415,000.

The foregoing description of the Letter Agreement does not purport to be complete and is qualified in its entirety by reference to the complete text of the Letter Agreement, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated by reference herein.

*Appointment of Roald G. Webster as Principal Accounting Officer*

On February 16, 2023, the Board of Directors of the Company (the "Board") appointed Roald G. Webster to serve as Vice President, Chief Accounting Officer of the Company, effective March 20, 2023 (the "Effective Date").

Mr. Webster, age 45, is a certified professional accountant with over 20 years of accounting experience. Prior to joining the Company, Mr. Webster served as Vice President and Corporate Controller at Bruker Corporation ("Bruker"), a publicly traded developer, manufacturer and distributor of high-performance scientific instruments and analytical and diagnostic solutions, from April 2018 to the present and as Director of Corporate Accounting from April 2017 through April 2018. Prior to Bruker, Mr. Webster served as Director of Financial Reporting and Technical Accounting at Agios Pharmaceuticals, Inc., a publicly traded pharmaceutical company, from November 2013 through April 2017. Earlier in his career, Mr. Webster held positions as an audit Senior Manager at Deloitte Touche Tohmatsu Limited, an Audit Director at RSM US LLP, and as an audit manager at Feeley & Driscoll, P.C. Mr. Webster is a graduate of Boston College Carroll School of Management and of Bentley College, where he earned a B.S. in accountancy.

In connection with Mr. Webster's appointment as Vice President, Chief Accounting Officer, the Company entered into an offer letter with Mr. Webster (the "Offer Letter") and will enter into its standard form severance agreement (the "Severance Agreement").

The Offer Letter sets forth customary terms relating to Mr. Webster's employment, including his annual base salary and his annual target bonus percentage. The Offer Letter also provides for Mr. Webster to receive a one-time signing bonus within a month of the Effective Date (the "Signing Bonus") and a one-time deferred hiring bonus in July 2023 (the "Deferred Bonus"), each of which will be subject to recoupment in whole or in part if Mr. Webster voluntarily resigns within 24 months following the Effective Date.

Subject to approval by the Compensation Committee of the Board (the "Compensation Committee"), the Company will grant to Mr. Webster an initial award of RSUs that will vest as to 60% of the underlying shares on the first anniversary of the grant date and as to the remaining 40% of the underlying shares on the second anniversary of the grant date, in each case, subject to Mr. Webster's continued employment with the Company through each vesting date. In addition, Mr. Webster will be eligible to participate in and receive future awards of RSUs and PSUs under

------

the Company's 2020 Omnibus Incentive Compensation Plan, subject to the approval of the Compensation Committee.

Pursuant to the Severance Agreement, Mr. Webster's employment will be terminable by either the Company without cause or by Mr. Webster for good reason. In the event that Mr. Webster's employment is terminated by the Company without "cause" or by Mr. Webster for "good reason," in each case as defined in the Severance Agreement, then in addition to payment of any accrued amounts and subject to Mr. Webster's timely executing a release of claims and continuing to comply with his restrictive covenant obligations, he will be entitled to receive an amount equal to the sum of one times his then-current base salary, plus one times his then-current target bonus, plus a prorated bonus for the year in which the termination occurs, payable in a lump sum within 15 days following the date of his termination, and reimbursement for additional costs he incurs for continued coverage under the Company's group health insurance under the Consolidated Budget Reconciliation Act of 1985 for up to 18 months.

Re: Retirement Separation Letter Agreement

Dear Tom:

Allegro MicroSystems, Inc., (the "<u>Company</u>") is most grateful for your dedication, commitment, and significant contributions to the Company. The Company has a strong desire to support you as you plan for your retirement, and we appreciate your willingness to ensure a smooth transition of your current responsibilities and appropriate succession planning.

As you have informed us, the date of your retirement will be Friday, June 2, 2023, or such earlier date as may be agreed to by you and the Company (the "<u>Retirement Date</u>"). You will remain full time through your retirement date, with flexibility to work from another work location at your discretion, provided you attend critical onsite management meetings, as required and agreed upon between the two of us.

The purpose of this letter agreement (the "<u>Letter</u>") is to memorialize our joint understanding regarding your retirement and to summarize the payments that you will be entitled to in connection therewith (the "<u>Retirement Payments</u>"). Please note that all Retirement Payments are subject to your compliance with the terms outlined herein, your continued employment until your Retirement Date and cooperating in good faith with the Company, and your continued employment is subject to your compliance with all of the Company's policies and procedures.

*<u>Retirement; Accrued Obligations</u>*

You and the Company agree that you will retire on the Retirement Date. Promptly following the Retirement Date, the Company will pay to you: (i) all accrued salary, less applicable federal, state, and local tax withholdings and deductions, (ii) all accrued, unused vacation through the Retirement Date, and (iii) any unreimbursed business expenses incurred by you prior to the Retirement Date, in accordance with the Company's expense reimbursement policy.

You will also be entitled to receive your FY23 Annual Incentive Plan (AIP) award, based on the actual AIP earnout calculations, to be paid at the end of the fiscal year when the AIP awards are calculated and paid. You will not be eligible for any FY24 AIP award.

*<u>Retirement Payments</u>*

Subject to your execution and non-revocation of a release of claims in a form determined by the Company (the "<u>Release</u>"), you will also receive retirement benefits, including: (i) the Health Premium Payment, as outlined and defined below, (ii) a New RSU Award, as outlined and defined below, and (iii) a cash-based retention award.

------

**Exhibit 10.1**

*Health Premium Payment.* For the twelve-month period beginning on your Retirement Date, you will be eligible to continue to participate in the Company's medical, dental and/or vision coverage at the same rates as active employees consistent with your benefit elections in place on your Retirement Date (the "<u>Health Premium Payment</u>"). The Health Premium Payment will run concurrently with COBRA, and, after the twelve (12) months, you will be eligible to elect COBRA for the remaining COBRA period and, at that time, you will be responsible for the full cost of COBRA.

*Existing Equity.* You and the Company acknowledge and agree that as of the Retirement Date, you will hold unvested performance-based restricted stock units ("<u>PSUs</u>"), and unvested time-based restricted stock units ("<u>RSUs</u>") under the Company's 2020 Omnibus Incentive Compensation Plan ("<u>Plan</u>"). The RSUs and PSUs will vest in accordance with the terms of the specific grant agreements under the Plan (the "<u>Award Agreements</u>"). Any RSUs and PSUs that vest on or prior to the Retirement Date will be distributed to you in accordance with the applicable termination provisions set forth in your respective Award Agreements. All RSUs and PSUs which are unvested as of the Retirement Date and as to which no portion of such PSU or RSUs vests pursuant to the applicable Award Agreement will be forfeited and cancelled without consideration therefor as of the Retirement Date (the "<u>Forfeited Awards</u>"). For the avoidance of doubt, the Forfeited Awards shall not include any PSUs or RSUs granted to you in May 2022.

*New RSU Award.* In addition, the Company will grant to you a one-time special RSU award (the "<u>New RSU Award</u>"), equal to a prorated portion of your Forfeited Awards, with the prorated amount calculated through the one-year anniversary of your Retirement Date (i.e., June 2, 2024) as if the Forfeited Awards had vested pro-rata through such date. With respect to determining the amount of the pro-rated PSUs, the value of the award shall be determined using performance equal to the greater of an award's: (i) target, or (ii) the prior quarter end performance estimate (as presented to the Compensation Committee) as of your Retirement Date.

The New RSU Award will contain restrictive covenants consistent with the Company's standard employee grant agreements and will provide that the New RSU Award will vest in full on your Retirement Date, subject to your: (i) execution on the Retirement Date and non-revocation of the Release, (ii) continued compliance with the restrictive covenants described in the New RSU Award, (iii) compliance with the terms and conditions of this Letter, and (iv) cooperating in good faith with the Company throughout the remainder of your employment through your Retirement Date and for a period of six (6) months after the Retirement Date (the "<u>Severance Conditions</u>"). Notwithstanding the foregoing, the New RSU Award will also be subject to formal approval and grant by the Compensation Committee.

*Retention Award.* In addition, you will receive a special one-time cash-based retention award in the amount of $415,000 if you remain employed with the Company through your Retirement Date. This special award will be paid to you at the time of your retirement, as soon as administratively possible, but no later than thirty (30) days after your Retirement Date.

Please contact Joanne Valente if you have any further questions regarding this Letter.
