 Exhibit 10.40 

Execution Version 
 AMENDED AND
RESTATED SEVERANCE AGREEMENT 
 THIS AGREEMENT (the “Agreement”) is entered into as of September 30, 2020 between Allegro
MicroSystems, LLC, a Delaware limited liability company (“Allegro”) and Max Glover, SVP, Worldwide Sales of Allegro (“Executive”). 

WHEREAS, if there occurs a registered initial public offering of securities of Allegro MicroSystems, Inc. (“AMI”) or of any newly
organized corporation or other business entity into which the assets or the ownership interests of AMI are merged or restructured (an “IPO”), Allegro wishs to ensure that Allegro executives will continue to exert maximum effort toward the
success of the Company and to continue their employment with Allegro without undue concern regarding the security of their employment. 
 NOW, THEREFORE,
contingent upon the occurrence of an IPO on or before March 31, 2021 the parties agree as follows: 
  

	1.	 Certain Definitions. 



For purposes of this Agreement, certain terms shall have the meaning set forth below: 

1.1     “Cause” means a good faith determination by the Board of Directors of Allegro MicroSystems, Inc. (“AMI”) of any
one or more of the following: (a) Executive’s (x) continued or repeated failure or refusal (after prior written notice thereof from the Board of Directors of AMI and Executive’s failure to cure the same (if curable) within ten
(10) calendar days of such written notice, and other than due to Executive’s disability) to substantially perform the duties required by Executive’s position with AMI or any of its subsidiaries (it being understood that
Executive’s failure to attain performance goals or targets or to otherwise fail to substantially perform the duties required by Executive’s position shall not constitute “Cause” hereunder if such failure is as a result of actions
taken or not taken in good faith and with reasonable belief that such actions or omissions were in the best interests of AMI and its subsidiaries) or (y) failure or refusal to follow lawful directives of the Board of Directors of AMI;
(b) gross negligence or willful misconduct (including unauthorized disclosure of material proprietary information) by Executive which results in a material detriment to AMI or any of its subsidiaries; (c) Executive’s conviction (by a
court of competent jurisdiction, not subject to further appeal) of, or pleading guilty to, a felony that involves fraud or moral turpitude or that is perpetrated against AMI or any of its subsidiaries, their respective businesses or any of their
respective assets, properties or personnel; or (d) a material breach by Executive of the Restrictive Covenants, this Agreement, or of any other written agreement with the Company to which Executive is a party. 












 1.2     The term “Company” means Allegro MicroSystems, LLC or any successor to
Allegro, including without limitation any entity that acquires all or substantially all of Allegro’s assets or any entity into which Allegro merges. 

1.3     The term “Company’s Governing Body” means the board of directors of AMI if the Company is then a subsidiary of AMI;
if not, the board of directors of the Company if the Company is then a corporation or the board of managers or the managing member of the Company within the meaning of the applicable limited liability act if the Company is then a limited liability
company; or, if none of the foregoing, the Company’s governing body under applicable law or its constituent documents. 
 1.4    
The term “Good Reason” shall mean the occurrence of any of the following without Executive’s prior written consent: (a) a material reduction in Executive’s base salary paid or payable by the Company and/or any of its
subsidiaries; or (b) a material reduction in the Target Bonus of Executive; (c) a material diminution in Executive’s authority, duties, responsibilities, or reporting relationship in connection with Executive’s employment with
the Company; (d) the relocation of Executive’s principal work location in connection with his employment by the Company to a facility or location more than thirty-five (35) miles from Executive’s present principal work location;
or (e) the Company has materially breached this Agreement, including without limitation a failure to comply with the assignment to successor requirement in Section 8. 

1.5     The term “Restrictive Covenants” means the restrictive covenants set forth in Executive’s Class L Common Stock
Grant Agreement between AMI and Executive dated October 1, 2019. 
 1.6     The term “Target Bonus” means the target bonus
for a fiscal year as specified for Executive under Allegro’s Annual Incentive Plan or any successor annual bonus plan maintained by the Company. In the event that a Target Bonus has not been established for a fiscal year because action has not
yet been taken within such fiscal year to approve the annual bonus plan target pool and Target Bonuses, the Target Bonus shall be the same as Executive’s Target Bonus for the preceding fiscal year. 

 

	2.	 Severance Benefit and Health Care Continuation Benefit Following Termination without
Cause. 


 2.1     Executive shall be entitled to a “Severance Benefit” as described in this
Section 2 in the event that the Company terminates Executive’s employment without Cause and the release described in Section 5 has become effective. 

2.2     In the event of termination without Cause, the Severance Benefit shall be equal to the sum of the following (the “Severance
Benefit”): 
  

	 	(a)	 100% of Executive’s annual base salary on the termination date. 



 

  
 2 














	 	(b)	 100% of Executive’s Target Bonus on the termination date; and 



 

	 	(c)	 a prorated bonus for the fiscal year in which termination occurs, determined by multiplying the Target Bonus on
the termination date by a ratio equal to the number of completed days of employment in the fiscal year prior to and including the termination date divided by the total number of days in such fiscal year. 



2.3     The applicable Severance Benefit shall be paid to Executive in a lump sum not later than fifteen (15) days following the
termination date if the Release described in Section has become effective. If the Release described in Section 5 has not become effective more than 15 days following the termination date, the Severance Benefit shall be paid not later than five
(5) days after the Release becomes effective. 
 2.4     Payment of the Severance Benefit shall be net of applicable withholding
taxes. 
 2.5     In addition to the Severance Benefit, if Executive is a participant on the termination date in a group health plan of
the Company that is subject to Section 601 et seq. of the Employee Retirement Income Security Act of 1974, as amended, or similar state health care continuation coverage law (“COBRA”), Executive shall be entitled for up to
eighteen (18) months after the termination date to Company payment of the entire cost of COBRA health insurance continuation coverage for Executive and Executive’s covered dependents, subject to the following conditions. The Company shall
notify Executive of the right to continue Executive’s health insurance coverage pursuant to COBRA. To the extent that Executive timely elects to accept continued health insurance coverage under COBRA, the Company shall pay or reimburse to
Executive the full monthly cost of Executive’s COBRA coverage. If Executive desires to continue health care coverage under COBRA after becoming eligible for other health insurance coverage, Executive may do so for the balance of the applicable
COBRA period at Executive’s expense consistent with the requirements of COBRA. Notwithstanding the foregoing, the Company shall not be required to provide Executive with the healthcare continuation coverage benefits in this Section 2.6 if
doing so would result in the imposition of penalties or other adverse consequences to the Company pursuant to the ACA or any successor legislation or regulations thereunder. Payment of the health care continuation coverage benefit pursuant to this
Section 2.6 shall be conditioned upon Executive’s timely execution of the Release described in Section 5 and the Release having become effective by its terms on or before the sixtieth (60th) day following Executive’s termination.

 2.6     If the Company, at the time of giving Executive notice of termination, specifies or requests a termination date later than the
notice date, Executive shall not be required to accept a termination date that is more than two weeks after the date of notice of termination, and the failure to agree to a later termination date shall not be construed as a voluntary termination by
Executive. The termination date for purposes of this Section 2, consistent with the preceding 

  
 3 













 
sentence, shall be the final day of employment of Executive by the Company. 
  

	3.	 AMI Stock Rights. 



Executive’s rights with respect to AMI stock awards, stock options, stock appreciation rights, and/or stock units that Executive may own or have a
conditional right to at the time of termination shall be determined in accordance with AMI’s Certificate of Incorporation, the Allegro MicroSystems, Inc. 2020 Omnibus Incentive Compensation Plan, the applicable grant agreements pursuant to
which Executive acquired such rights and any other applicable governing documents, as any such documents may be amended from time to time. Notwithstanding any provision to the contrary in any such documents, for purposes of determining the extent to
which Executive is vested in any such rights, termination of the Executive for Good Reason pursuant to Section 4 of this Agreement shall be treated in the same manner as a termination by the Company without Cause. 

 

	4.	 Voluntary Termination for Good Reason or Otherwise. 



Executive shall be entitled to terminate employment with the Company and receive the Severance Benefit, the health care continuation benefit and the stock
rights as specified in Sections 2 and 3, upon the following conditions, provided that Executive timely executes the Release described in Section 5 and the Release becomes effective by its terms on or before the sixtieth (60th) day following
Executive’s termination: 
 4.1     If an event constituting Good Reason occurs, and Executive gives the Company written notice
within sixty (60) days following the event of Good Reason, detailing why Executive believes a Good Reason event has occurred, the Company shall have thirty (30) days after receipt of such written notice to remedy or cure the event of Good
Reason. If the Company does not remedy or cure the event within such period and the event constitutes Good Reason as defined in this Agreement, Executive’s employment shall be deemed terminated for Good Reason at the end of such thirty day cure
period. Executive’s notice shall be delivered to the Company’s Governing Body. 
 4.2     The termination date for purposes of
Section 5.1 shall be, if earlier than the expiration of the thirty day cure period described in Section 5.1, the date that the Company gives written notice to Executive that the Company does not intend to cure the event of Good Reason.

 4.3     If an event of Good Reason is (or includes) a material reduction in annual base salary or Target Bonus as described in
Section 1.4(b), the applicable severance benefit shall be calculated on the basis of annual base salary and Target Bonus as the same existed immediately prior to such reduction. 

 

  
 4 













 4.4     In the absence of an event of Good Reason, termination by Executive for personal
reasons if payment of the benefits hereunder is approved by the Company’s Governing Body upon the recommendation of the Compensation Committee of such Company’s Governing Body. 

 

	5.	 Release Requirement; Compliance with Restrictive Covenants. 



5.1 As a prerequisite to the Company’s payment of the benefits and payments described in this Agreement, Executive shall have executed and delivered to
the Company a general release of claims (“Release”) and the Release shall have become effective in accordance with its terms as specified in this Section 7 on or prior to the sixtieth (60th) day following Executive’s termination.
The Release shall be substantially in the form attached as Exhibit A. The Company may modify the Release versus the form attached as Exhibit A in order to specify the amount of the Severance Benefit or other benefits, comply with changes in law, or
reflect changes in relevant facts (such as the name of the Company). However, the Company shall not include any additional requirements or provisions in the Release, including without limitation any restrictive covenants concerning post-termination
activities of Executive without Executive’s prior written consent. 
 5.2     The Company shall deliver the form of Release to
Executive on or prior to the date of termination. Executive shall have at least twenty-one (21) days within which to consider the Release. Executive shall have up to seven (7) days after execution
and delivery of the Release to revoke the Release. The Release shall not become effective until the revocation period has expired without revocation of the Release by Executive. 

5.3     The health insurance continuation benefit described in Section 2.6 shall be provided to Executive on a monthly basis after the
termination date on the assumption that the Release will become effective, provided that entitlement to such benefit shall expire if the Release does not become effective within sixty (60) days after the termination date and, in such case,
Executive shall be required to promptly return amounts paid on his or her behalf to the Company. 
 5.4     Executive’s entitlement
to receive and to retain the benefits and payments described in this Agreement shall be conditioned upon Executive’s compliance with the Restrictive Covenants, which Restrictive Covenants are hereby incorporated in their entirety as though
fully set forth herein and which Restrictive Covenants shall survive any termination of Executive’s Class L Common Stock Grant Agreement between AMI and Executive dated October 1, 2019. 

 

	6.	 Exclusive Remedy. 



Executive’s receipt of the Severance Payment and other consideration provided in this Agreement shall be in lieu of any benefits specified under any prior
severance agreement between Allegro and Executive, any other severance policy maintained by the Company; any benefits pursuant to any other agreement or understanding between Executive and the Company relating to termination of employment; and any
benefits under the Company’s Annual Incentive Plan or its 

  
 5 













 
successor for the fiscal year in which termination occurs. However, this Agreement shall not divest Executive of Executive’s right to distributions from Allegro’s Executive Deferred
Compensation Plan or any right to vested benefits under the terms of the Company’s benefit plans, to be paid accrued wages and vacation through the termination date or to be reimbursed for properly substantiated business expenses in accordance
with the Company’s expense reimbursement policy. 
  

	7.	 Successors and Assigns. 



This Agreement shall inure to the benefit of, and shall be binding upon, the Company and its successors and assigns, including any successor entity by merger,
consolidation or transfer of all or substantially all of the Company’s assets. The Company shall require and cause any person, group or entity that acquires all or substantially all of the assets of the Company to accept a written assignment of
this Agreement by the Company, and to acknowledge in such document that the acquiror accepts the assignment and undertakes to perform this Agreement in accordance with its terms. 

 

	8.	 Amended or Successor Agreements. 



If requested by the Company, Executive will in good faith consider and negotiate an amended or a successor agreement in order to address revised circumstances
(for example, restructuring of the Allegro group of companies), providing that there is no diminution in the level of benefits available to Executive hereunder. 
  

	9.	 Miscellaneous Provisions. 



 

	9.1	 Arbitration. Any claim, dispute or controversy arising out of this Agreement, the interpretation,
validity or enforceability of this Agreement or the alleged breach thereof shall be settled by binding arbitration. The arbitration shall be conducted in accordance with the rules of the American Arbitration Association in Boston, Massachusetts or
elsewhere by mutual agreement. The Company shall bear responsibility for all costs of arbitration and shall reimburse Executive for his or her reasonable attorneys’ fees. Judgment may be entered on the arbitration award in any court having
jurisdiction. 


  

	9.2	 Governing Law. This Agreement shall be construed in accordance with and governed by the laws of the
state of New Hampshire. 


  

	9.3	 Entire Agreement. This Agreement constitutes the entire agreement and understanding between Executive
and Company concerning the subject matter hereof, and supersedes all prior negotiations or understandings between the parties, whether written or oral, including employment offer letters, concerning such matter. 



 

	9.4	 Employment at Will. Executive’s employment with the Company shall remain at will.



  

  
 6 













 Nothing in the Agreement shall provide Executive with any right to continued employment with
the Company for any specific period of time, or interfere with or restrict the right of either Executive or the Company to terminate Executive’s employment at any time. 
  

	9.5	 Application of Section 409A. The payments contemplated by this Agreement are intended
to be exempt from, or to comply with the requirements of, Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and this Agreement shall be interpreted with that intent. Notwithstanding the foregoing, the tax
treatment of amounts payable and benefits provided under this Agreement is not warranted or guaranteed, and neither the Company, nor any of its members, shareholders, employees, directors, officers, agents or affiliates, shall be held liable for any
taxes, interest, penalties or other monetary amounts owed by Executive or any other taxpayer as a result of this Agreement, including by reason of Section 409A or any similar State statute. Notwithstanding anything to the contrary in this
Agreement, if at the time Executive’s employment terminates, Executive is a “specified employee,” as defined below, any and all amounts payable under this Agreement on account of Executive’s separation from service that would
(but for this provision) be payable within six (6) months following the date of such separation from service, shall instead be paid on the next business day following the expiration of such six (6) month period or, if earlier, upon
Executive’s death; except (A) to the extent of amounts that do not constitute a deferral of compensation within the meaning of Treasury regulation Section 1.409A-1(b) (including without
limitation by reason of the safe harbor set forth in Section 1.409A-1(b)(9)(iii), as determined by the Company in its reasonable good faith discretion); (B) benefits which qualify as excepted welfare
benefits pursuant to Treasury regulation Section 1.409A-1(a)(5); or (C) other amounts or benefits that are not subject to the requirements of Section 409A of the Code. For purposes of this
Agreement, with respect to payments that are subject to Section 409A and that are payable upon or with reference to Executive’s termination of employment, all references to “termination of employment” and correlative phrases
shall be construed to require a “separation from service” (as defined in Section 1.409A-1(h) of the Treasury regulations after giving effect to the presumptions contained therein), from the
Company, and the term “specified employee” means an individual determined by the Company to be a specified employee of the Company under Treasury regulation Section 1.409A-1(i). Each payment
made under this Agreement shall be treated as a separate payment and the right to a series of installment payments under this Agreement is to be treated as a right to a series of separate payments. To the extent required by Section 409A, if the
period for executing and not revoking the Release spans two taxable years, the Severance Benefit shall be paid in the second taxable year. Any tax gross up payment hereunder shall be made no later than the end of the calendar year following the
calendar year in which the related taxes are remitted to the appropriate tax authorities, or at such other specified time or schedule that may be permitted under Treas. Reg. Section 1.409A-3(i)(1)(v).

	9.6	 [RESERVED] 


  

	9.7	 Proprietary Information. Nothing in this Agreement or the Release shall be construed as an elimination
or waiver of Executive’s obligations not to disclose confidential or proprietary information to third parties as required by Company policy and any agreements between the Company and Executive that were executed during Executive’s
employment with the Company. 


  

	9.8	 Waiver; Amendment. No waiver of any breach of this Agreement shall be construed to be a waiver of any
other breach of this Agreement. No waiver or amendment of this Agreement shall be effective unless set forth in a written document signed by Executive and an executive of the Company authorized by the Company’s Governing Body.



  

	9.9	 Notices. Any notices required or permitted by this Agreement shall be in writing, and may be transmitted
by personal delivery, by courier service or by e-mail if receipt of such e-mail is acknowledged by the receiving party. Notices shall be addressed to the
recipient’s principal business office. 


  

	9.10	 Agreement Contingent upon IPO. This Agreement shall not be effective unless there occurs, on or before
March 31, 2021, a registered initial public offering of securities of AMI or of any newly organized corporation or other business entity into which the assets or the ownership interests of AMI are merged or restructured. 



IN WITNESS WHEREOF, the parties have executed this Agreement as of the date and year first above written.
