## Exhibit 4.1

**Exhibit 4.1**

**BOARD OBSERVER AGREEMENT**

This BOARD OBSERVER AGREEMENT, dated as of January 21, 2026 (this "<u>Agreement</u>"), is entered into by and among Alta Equipment Group Inc., a Delaware corporation (the "<u>Company</u>"), and Deven Petito, an individual (the "<u>Board Observer</u>"). The Company and the Board Observer are sometimes together referred to herein as the "<u>Parties</u>," and each, a "<u>Party</u>."

WHEREAS, pursuant to that certain Cooperation Agreement (the "<u>Cooperation Agreement</u>"), dated the date hereof, between the Company and Mill Road Capital III, L.P., the Company desires to appoint the Board Observer as a single non-voting observer to the board of directors of the Company (the "<u>Board</u>"); and

WHEREAS, the Parties desire to set forth their respective rights and obligations with respect to the foregoing matters, upon the terms and subject to the conditions set forth herein.

NOW, THEREFORE, the Parties, intending to be legally bound, hereby agree as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.<u>Board Observer</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)The Company hereby grants the Board Observer the right to attend meetings of the Board and any committees thereof, in each case solely as a non-voting observer, subject in all respects to the terms and conditions of this Agreement and that certain Cooperation Agreement, dated January 21, 2026 (the "<u>Cooperation Agreement</u>"), including the Company's rights of exclusion set forth therein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Subject to this <u>Section 1(b)</u>, the Board Observer shall be entitled to be present at meetings of the Board and its committees, and shall comply with all rules or procedures established by the Board applicable to directors generally. The Board Observer shall be notified of meetings of the Board and its committees, including such meeting's time, place and agenda, in the same manner and at the same time as members of the Board or such committee, as applicable. Subject to this <u>Section 1(b)</u>, the Board Observer shall be entitled to receive copies of materials distributed to the full Board or any committee in connection with any meeting thereof or as are otherwise distributed to the full Board or such committee (collectively, the "<u>Board Materials</u>"), in each case in the same manner and at the same time as such Board Materials are provided to members of the Board or such committee, as applicable. The rights granted to the Board Observer in the preceding sentences of this <u>Section 1(b)</u> are referred to as the "<u>Observer Rights</u>." Notwithstanding anything to the contrary herein, the Company reserves the right to exclude the Board Observer from access to any Board Materials or any portion thereof, or any meeting of the Board or any of its committees, or any portion thereof if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)a majority of the directors conclude in good faith after consultation with the Company's Chief Legal Officer or outside legal counsel, that such exclusion is reasonably necessary or advisable to preserve the attorney-client privilege or work product protection between the Company or its Affiliates and Associates (each as defined in Rule 12b-2 promulgated by the SEC under the Exchange Act of 1934, as amended (together with the rules and regulations thereunder, the "<u>Exchange Act</u>")) and their respective legal counsel; <u>provided</u>, however, that any such exclusion shall apply only to such portion of the Board

------

Materials or such portion of the meeting that would be required to preserve such privilege or protection and not to any other portion thereof; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)upon advice of the Company's Chief Legal Officer or outside legal counsel, there exists an actual or reasonably anticipated conflict of interest with respect to the Board Observer and a particular matter or transaction being discussed in a meeting of the Board, including any matter relating to the Company's or its Affiliates' relationship, contractual or otherwise, with Mill Road or its Affiliates or any actual or potential transaction between or involving the Company or its Affiliates and Mill Road or its Affiliates; <u>provided</u>, however, that any such exclusion shall apply only to such portion of the Board Materials or such portion of the meeting to which such conflict of interest relates;

<u>provided</u> that, in each case, it is understood that if the Observer Rights are limited pursuant to this <u>Section 1(b)</u>, the Board will notify the Board Observer of such limitation as soon as reasonably practicable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)The Board Observer is not a member of the Board or any committee thereof and, accordingly, shall not be permitted to vote on any matter at any meeting of the Board or any committee thereof or be counted for purposes of determining whether a quorum is present to conduct its business. For the avoidance of doubt, the Board Observer shall not have, and shall not be deemed to have, any fiduciary or other duties to the Company or its stockholders, or any duties otherwise applicable to members of the Board or any committee thereof, solely by virtue of the Board Observer's appointment as a board observer hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)In the event this Agreement is terminated pursuant to <u>Section 3</u> below, or upon the termination or expiration of the Cooperation Agreement, the Company may immediately terminate all rights granted to the Board Observer hereunder. In addition, the rights and obligations of the Board Observer shall automatically terminate upon the death or permanent disability of such individual or upon the resignation or other cessation of service of such individual upon written notice to the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.<u>Confidentiality</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)Except as set out in <u>Section 2(a)(ii)</u> below, "<u>Confidential Information</u>" means all non-public or confidential information disclosed on or after the date of this Agreement by the Company, the Board, or its controlled Affiliates to the Board Observer, or (for the benefit of the Board Observer) to any of the Board Observer's Affiliates, or the Board Observer's or its Affiliates' employees, officers, directors, partners, shareholders, agents, contractors, attorneys, accountants, or advisors (collectively, "<u>Representatives</u>") in each case pursuant to the Observer Rights, whether disclosed orally or disclosed or accessed in written, electronic or other form or media, and whether or not marked, designated or otherwise identified as "confidential," including, without limitation: (a) all information concerning the Company, the Board, or their respective Affiliates, and their customers', suppliers' and other third parties' past, present or future business affairs, including, without limitation, finances, customer information and data, supplier information, products, services, organizational structure and internal practices, forecasts, sales and other financial results, records and budgets, and business, marketing,

------

development, sales and other commercial strategies; (b) the Company's unpatented inventions, ideas, methods and discoveries, trade secrets, know-how, unpublished patent applications and other confidential intellectual property; (c) all designs, specifications, documentation, components, source code, object code, images, icons, audiovisual components and objects, schematics, drawings, protocols, processes and other visual depictions, in whole or in part, of any of the foregoing; (d) any third-party confidential information included with, or incorporated in, any information provided by the Company or the Board to the Board Observer or its Representatives; and (e) all notes, analyses, compilations, reports, forecasts, studies, samples, data, statistics, summaries, interpretations and other materials (the "<u>Notes</u>") prepared by the Board Observer or its Representatives to the extent that they contain, are based on, or otherwise reflect or are derived from, in whole or in part, any of the foregoing. For avoidance of doubt, "<u>Representatives</u>" shall include Mill Road Capital III, L.P. (the "<u>Fund</u>"), Mill Road Capital III GP, LLC and Mill Road Capital Management LLC ("<u>MRCM</u>"), and their respective Representatives.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)Except as required by applicable federal, state, or local law or regulation, the term "<u>Confidential Information</u>" as used in this Agreement shall not include information that: (a) at the time of disclosure is, or thereafter becomes, generally available to the public other than as a result of, directly or indirectly, any violation of this Agreement by the Board Observer or any of its Representatives; (b) at the time of disclosure is, or thereafter becomes, available to the Board Observer on a non-confidential basis from a third-party source, provided that such third party, to the knowledge of the Board Observer, is not and was not prohibited from disclosing such Confidential Information to the Board Observer by a legal, fiduciary, or contractual obligation to the Company with respect to such information; (c) was known by or in the possession of the Board Observer or its Representatives before being disclosed by or on behalf of the Company under this Agreement; or (d) was or is independently developed by the recipient without reference to or use of, in whole or in part, any of the Confidential Information.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)The Board Observer shall keep confidential any Confidential Information except as expressly permitted by this Agreement, subject to <u>Section 2(d)</u> below. The Board Observer may disclose the Confidential Information to the Board Observer's Representatives solely on a need-to-know basis and only to the extent reasonably necessary for the purposes described below, provided that the Board Observer agrees and shall be responsible for instructing all such Representatives to keep such Confidential Information confidential and not to disclose such Confidential Information to any third party without the prior written consent of the Company. The Board Observer and its Representatives may use Confidential Information solely in connection with (i) the Observer Rights granted pursuant to <u>Section 1(b)</u> of this Agreement, (ii) monitoring, reviewing, analyzing and evaluating the investment of the Fund and its Affiliates and Associates in the Company and (iii) exercising its rights as a stockholder of the Company (including without limitation voting and investment decisions), provided that the Board Observer and its Representatives do not disclose Confidential Information in connection therewith, and for no other purpose. For avoidance of doubt, any action or omission that is primarily caused by factors other than Confidential Information shall be deemed not to constitute use of Confidential Information.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)The Company acknowledges that in the ordinary course the Board Observer and its Representatives (including through funds and accounts managed or advised by MRCM or any of

------

its Affiliates or Associates) may analyze and invest in securities, instruments, businesses and assets of third parties in the same or similar lines of business as the Company and its subsidiaries. Notwithstanding any other provision in this Agreement, neither the Board Observer nor any Representative (including through funds and accounts managed or advised by MRCM or any of its Affiliates or Associates) shall be constrained in any way from engaging in such activities under this Agreement, provided that no Confidential Information is used in connection therewith and the Board Observer and all Representatives otherwise comply in all respects with the confidentiality and use restrictions set forth in this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Notwithstanding anything to the contrary herein, if the Board Observer or any of the Board Observer's Representatives is required or requested by applicable law, rule or regulation or by any order or similar directive of a court of competent jurisdiction, or by any other governmental or regulatory authority, to disclose Confidential Information, then, except where giving notice to the Company is prohibited by law, rule or regulation, the Board Observer or any of the Board Observer's Representative shall, to the extent legally permissible, give the Company written notice of such requirement or request as soon as reasonably practicable and shall consult with and afford the Company a reasonable opportunity to contest the necessity of disclosing such Confidential Information or seek an appropriate protective order. If, in the absence of a protective order, the Board Observer or any of the Board Observer's Representatives is compelled to disclose such Confidential Information, the Board Observer or any of the Board Observer's Representatives may disclose only that portion of the requested information that the Board Observer or any of the Board Observer's Representatives is legally required to disclose; provided that, if permitted by applicable law, rule or regulation, the Board Observer shall promptly give the Company written notice of the Confidential Information to be disclosed as far in advance of its disclosure as reasonably practicable and use commercially reasonable efforts, at the Company's advance expense, to obtain reasonable assurances that confidential treatment will be accorded to such Confidential Information. Notwithstanding anything to the contrary herein, Board Observer or any of the Board Observer's Representatives may disclose any information without notice to the Company to the extent requested or required by any applicable banking, financial, accounting, securities, or similar regulatory authority (including self-regulatory organizations) during the course of any routine regulatory audit or examinations by or blanket document requests from such authorities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)The Parties acknowledge and agree that the disclosure of Confidential Information provided to the Board Observer or the Board Observer's Representatives pursuant to this Agreement is not intended to, and shall not, waive or diminish any attorney-client privilege, work product protection or other applicable privilege that may apply to such Confidential Information, and that all such privileges shall continue to apply to the fullest extent permitted by law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)The Board Observer's and the Board Observer's Representatives' confidentiality and use obligations under this <u>Section 2</u> shall survive for twelve (12) months after termination of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.<u>Termination</u>. Except for the confidentiality obligation (which term is set forth in <u>Section 2(f)</u> above), this Agreement and each Party's obligation under this Agreement will terminate upon the earliest to occur of (i) the expiration or termination of the Cooperation Agreement in accordance with its terms, (ii) the delivery by the Board Observer of written notice to the Company of his resignation from such position, or the death or permanent disability of the

------

Board Observer, (iii) the termination of the Board Observer's status as such pursuant to the terms of the Cooperation Agreement or (iv) the delivery by the Company of written notice of termination of this Agreement to the Board Observer if the Board Observer shall not have cured a material breach of this Agreement (if capable of being cured) within fifteen (15) days after receipt by the Board Observer of written notice from the Company specifying the material breach in reasonable detail; provided, however, that no termination of this Agreement will relieve any Party hereto from any liability for a breach of this Agreement prior to such termination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.<u>Trading Restrictions</u>. The Board Observer acknowledges that the Confidential Information may constitute material non-public information under applicable U.S. federal and state securities laws and regulations and that such laws and regulations may restrict the ability to engage in transactions in securities while in possession of such information.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.<u>Counterparts</u>. This Agreement may be executed in two or more counterparts, each of which will be considered one and the same agreement and will become effective when counterparts have been signed by each of the Parties and delivered to the other Party (including by means of electronic delivery or facsimile).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.<u>Specific Performance</u>. Each Party acknowledges and agrees that irreparable injury to the other Party would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and that money damages may not be an adequate remedy for such a breach. It is accordingly agreed that each Party shall be entitled to specific enforcement of, and injunctive relief to prevent any violation of, the terms hereof, without proving the inadequacy of money damages and without posting any bond. Each Party agrees to waive any bonding requirement under any applicable law in the case any other Party seeks to enforce the terms by way of equitable relief.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.<u>APPLICABLE LAW AND JURISDICTION</u>. THIS AGREEMENT WILL BE GOVERNED BY, AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF DELAWARE WITHOUT REFERENCE TO CONFLICTS OF LAWS PRINCIPLES. EACH OF THE PARTIES IRREVOCABLY AGREES THAT ANY LEGAL ACTION OR PROCEEDING TO ENFORCE THIS AGREEMENT WILL BE BROUGHT EXCLUSIVELY IN (A) THE DELAWARE COURT OF CHANCERY IN AND FOR NEW CASTLE COUNTY, (B) IN THE EVENT (BUT ONLY IN THE EVENT THAT SUCH COURT DOES NOT HAVE SUBJECT MATTER JURISDICTION OVER SUCH ACTION), THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF DELAWARE OR (C) IN THE EVENT (BUT ONLY IN THE EVENT) SUCH COURTS IDENTIFIED IN CLAUSES (A) AND (B) DO NOT HAVE SUBJECT MATTER JURISDICTION OVER SUCH ACTION, ANY OTHER DELAWARE STATE COURT (COLLECTIVELY, THE "<u>CHOSEN COURTS</u>"). EACH OF THE PARTIES IRREVOCABLY WAIVES THE RIGHT TO TRIAL BY JURY IN ANY SUCH ACTION OR PROCEEDING. EACH OF THE PARTIES HEREBY IRREVOCABLY SUBMITS TO THE PERSONAL JURISDICTION OF THE CHOSEN COURTS, AND IRREVOCABLY WAIVES ANY ARGUMENT THAT THE CHOSEN COURTS ARE AN INCONVENIENT OR IMPROPER FORUM. EACH PARTY CONSENTS TO SERVICE OF PROCESS BY A REPUTABLE OVERNIGHT DELIVERY SERVICE, SIGNATURE REQUESTED, TO THE

------

ADDRESS OF SUCH PARTY'S PRINCIPAL PLACE OF BUSINESS OR AS OTHERWISE PROVIDED BY APPLICABLE LAW.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.<u>Notice.</u> All notices, consents, requests, instructions, approvals and other communications provided for in this Agreement and all legal process in regard hereto shall be in writing and shall be deemed validly given, made or served, (a) if given by email, when such email is transmitted to the email address set forth below (so long as the sender of such email does not receive an automatic message indicating that the recipient did not receive such email) or (b) if given by any other means, when actually received during normal business hours at the address specified in this <u>Section 8</u>:

In the event of such vacancy, or at any time at Mill Road's election, Mill Road shall be entitled to select another individual employed by or affiliated or associated with Mill Road to act as the Observer (a "<u>Successor Observer</u>"), subject to the prior approval of the Board, with such approval not to be unreasonably withheld, conditioned or delayed, until the earlier to occur of (x) the Expiration Date and (y) the designation of another Successor Observer in accordance with this <u>Section 1(a)(ii)</u>, provided that the Successor Observer shall have reasonable qualifications and experience to serve as a board observer, including relevant industry, investment and board-level experience, and shall not present any conflict of interest or regulatory, reputational or fiduciary concern reasonably identified by the Board and disclosed to Mill Road in writing in reasonable detail (the "<u>Observer Qualifications</u>").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)The Company shall promptly take all necessary actions to install an approved Successor Observer following Board approval (not to be unreasonably withheld, conditioned or delayed); provided, that the Board may reject any proposed Successor Observer if with reasonable promptness (1) the Board reasonably determines, after consultation with counsel if appropriate, that such person fails to satisfy the Observer Qualifications and (2) such failures and the reasons therefor are disclosed to Mill Road in

------

writing in reasonable detail. If the Successor Observer initially proposed by Mill Road is rejected based on a failure to satisfy the Observer Qualifications, Mill Road shall be entitled, until the earlier to occur of (x) the Expiration Date and (y) the appointment of a Successor Observer in accordance with <u>Section 1(a)(ii)</u> to continue proposing persons as the Successor Observer and any such proposed person shall be promptly installed as the Successor Observer (subject to the Board's right to reject such person's candidacy as Successor Observer with reasonable promptness for a failure to satisfy the Observer Qualifications). The onboarding of any approved Successor Observer will be through a reasonable and customary process no more onerous, burdensome or time consuming than the process for onboarding the Initial Observer, and there will be no procedure, policy or other obstacle implemented with the intent or effect of prejudicing the Successor Observer's ability to timely act in such capacity. Nothing herein shall restrict the Company's ability to modify such procedures in a reasonable manner from time to time in the ordinary course. The Company shall use commercially reasonable efforts to complete such procedures within fifteen (15) business days after nomination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv)Notwithstanding anything in this Agreement to the contrary, the rights with respect to the designation of a Successor Observer pursuant to this <u>Section 1(a)</u> shall be conditioned on Mill Road, together with its Affiliates and Associates (each as defined in Rule 12b-2 promulgated by the SEC under the Exchange Act of 1934, as amended (together with the rules and regulations thereunder, the "<u>Exchange Act</u>")) (which shall be deemed to include Mill Road Capital III GP, LLC, Mill Road Capital Management, LLC and funds and accounts managed by them or any of their Affiliates or Associates), continuously having aggregate beneficial ownership of at least 4.9% of the shares of the common stock of the Company, par value $0.01 per share ("<u>Common Stock</u>"), outstanding at such time. Upon the Company's reasonable request in writing, Mill Road shall promptly certify its compliance with this ownership requirement in writing; provided, however, that no such certification shall be required if a Schedule 13D or 13G on file with the Securities and Exchange Commission, as amended, shall demonstrate such beneficial ownership.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Subject to the terms of this Agreement and the Board Observer Agreement, the Company agrees that the Observer may attend meetings (including telephonic or videoconference meetings), subject to the recusal provisions below, of the Board and its committees, in each case, solely in a non-voting observer capacity. The Observer may participate fully in discussions of matters brought to the Board and its committees for consideration, but in no event shall the Observer: (i) be deemed to be a member of the Board or any committee thereof; (ii) have the right to propose or offer any motions or resolutions of the Board or any committee thereof; or (iii) have the right to vote with respect to any motions or resolutions proposed or offered to the Board or any committee thereof or otherwise have any power to cause the Company to take, or not to take, any action. The presence or absence of the Observer shall not be required or taken into account for purposes of establishing a quorum. The Company shall provide to the Observer copies of notices, minutes, consents, and other materials that it provides to the directors of the Company (collectively, "<u>Board Materials</u>"), in each case in the same manner and at the same time as such Board materials are provided to members of the Board or such committee, as applicable. Notwithstanding anything to the contrary herein, the Company reserves the right to exclude the Board Observer from access to any Board Materials or any portion thereof, or any meeting of the Board or any of its committees, or any portion thereof if (A) a majority of the directors conclude

------

in good faith after consultation with the Company's Chief Legal Officer or outside legal counsel, that such exclusion is reasonably necessary or advisable to preserve the attorney-client privilege or work product protection between the Company or its Affiliates and their respective legal counsel; <u>provided</u>, however, that any such exclusion shall apply only to such portion of the Board Materials or such portion of the meeting that would be required to preserve such privilege or protection and not to any other portion thereof; or (B) upon advice of the Company's Chief Legal Officer or outside legal counsel, there exists an actual or reasonably anticipated conflict of interest with respect to the Board Observer and a particular matter or transaction being discussed in a meeting of the Board, including any matter relating to the Company's or its Affiliates' relationship, contractual or otherwise, with Mill Road or its Affiliates or any actual or potential transaction between or involving the Company or its Affiliates and Mill Road or its Affiliates; <u>provided</u>, however, that any such exclusion shall apply only to such portion of the Board Materials or such portion of the meeting to which such conflict of interest relates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)Mill Road hereby agrees that any Confidential Information (as defined in the Board Observer Agreement) disclosed to the Observer pursuant to the Observer Rights (as defined in the Board Observer Agreement) may be shared by the Observer with Mill Road and its Affiliates and Associates only in accordance with, and subject to, the confidentiality and use restrictions set forth in the Board Observer Agreement, and that Mill Road and its Affiliates and Associates shall be bound by, and responsible for compliance with, such confidentiality and use restrictions to the same extent as if they were parties to the Board Observer Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)<u>Stockholder Meetings.</u> At any annual or special meeting of stockholders of the Company (and at any adjournments or postponements thereof) during the Standstill Period, Mill Road shall appear in person or by proxy at such meeting for quorum purposes and shall vote, or cause to be voted (whether directly or through one or more proxies or other duly authorized designees), all shares of Common Stock over which Mill Road or any of its Affiliates and Associates has voting power, (A) in favor of all directors nominated by the Board for election at any such meeting, and (B) in accordance with the Board's recommendation with respect to any proposal to be submitted to the stockholders of the Company; <u>provided</u>, <u>however</u>, that Mill Road shall be permitted to vote in its discretion on any proposal in respect of any Extraordinary Transaction (as defined below), any amendment to the certificate of incorporation or bylaws of the Company, any shareholder rights plan, poison pill or other takeover defense, any reincorporation, domestication or conversion, or any issuance of securities (excluding the adoption or amendment of any employee benefit plan (as defined in Rule 405 under the Securities Act of 1933, as amended) or any issuance thereunder).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)<u>Board Observer Agreement.</u> Concurrently with the execution and delivery of this Agreement, the Company has entered into a board observer agreement (the "<u>Board Observer Agreement</u>") with Deven Petito. In the event of any Successor Observer, the Company shall enter into a board observer agreement with the Successor Observer on substantially identical terms.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.<u>Standstill Restrictions.</u> During the Standstill Period (unless specifically requested in writing by the Company), Mill Road shall not, and shall cause its Affiliates and Associates not to, directly or indirectly, in any manner, alone or in concert with others:

------

basis as other stockholders of the Company, or from participating in any such transaction that has been approved by the Board) or (C) any other material change in the Company's or any of its subsidiaries' operations, business, corporate strategy, corporate structure, capital structure or allocation, or share repurchase or dividend policies; <u>provided</u>, for the avoidance of doubt, that Mill Road and its Affiliates and Associates shall be entitled to engage in private discussions with respect to such matters with general or limited partners, members or stockholders of Mill Road or its Affiliates or Associates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h)communicate with the Company's stockholders or others pursuant to Rule 14a-1(l)(2)(iv) under the Exchange Act (other than pursuant to clause (B) thereof);

------

For the avoidance of doubt, the Parties acknowledge and agree that Mill Road and its Affiliates and Associates (including the Observer) intend to continue to engage in non-public discussions with members of management of the Company and the Board and nothing in this <u>Section 2</u> shall be deemed to prevent or impede such discussions from occurring, so long as such discussion is not intended to, and would not reasonably be expected to, require any public disclosure of such discussion. The Company shall notify Mill Road in writing upon the occurrence of the Expiration Date.

For purposes of this Agreement, the "<u>Standstill Period</u>" shall mean the period from and after the Effective Date until the earlier of the Expiration Date or the termination of this Agreement by Mill Road in accordance with its terms. As used herein, "<u>Extraordinary Transaction</u>" means any merger, acquisition, amalgamation, tender offer, exchange offer, recapitalization, restructuring, disposition, distribution, spin-off, asset sale, joint venture or other business combination involving the Company or any of its subsidiaries or that relates to or would result in a Change of Control.

The obligations in <u>Section 1(c)</u> and the restrictions in this <u>Section 2</u> shall terminate automatically if (a) the Company enters into a definitive agreement with a third party that, upon consummation, is reasonably anticipated to constitute a Change of Control or (b) a third party commences a tender or exchange offer that, if consummated, is reasonably anticipated to constitute a Change of Control; <u>provided</u>, that if such Change of Control, and all other proposed Extraordinary Transactions publicly announced thereafter by any other third party or parties, are abandoned or terminated prior to the consummation or closing of any such Extraordinary Transaction, then the obligations in <u>Section 1(c)</u> and the restrictions in this <u>Section 2</u> shall be automatically reinstated and shall continue in full force and effect in accordance with their terms, subject to any subsequent expiration or termination pursuant to this <u>Section 2</u>.

Notwithstanding anything to the contrary in this Agreement, nothing in this Agreement (including the restrictions in this <u>Section 2</u>) will prohibit or restrict Mill Road, any of its Affiliates or Associates or any Representative thereof from negotiating, evaluating and/or trading, directly or indirectly, in any mutual fund, exchange-traded fund, benchmark fund or broad basket of securities which may contain or otherwise reflect the performance of, but not primarily consist of, securities of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.<u>Press Release; Form 8-K; Publicity</u>.

The foregoing sentence shall not restrict the ability of any Party to (1) comply with any subpoena or other legal process or respond to a request for information from any governmental or regulatory authority with jurisdiction over the Party from whom information is sought, in each case solely to the extent legally required and after consultation with outside counsel, or (2) make private statements to directors or employees of the Company or Mill Road in circumstances in which public dissemination of such statements would not reasonably be anticipated. Nothing in this paragraph shall limit either Party's right to respond publicly to statements made by the other Party in breach of this Agreement, and any such response shall not itself be deemed a violation hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.<u>Representations of the Company.</u> The Company represents and warrants to Mill Road that (a) the Company has the corporate power and authority to execute and deliver this Agreement and to bind it hereto, (b) this Agreement has been duly and validly authorized, executed and delivered by the Company, constitutes a valid and binding obligation and agreement of the Company, and is enforceable against the Company in accordance with its terms (subject to applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and other similar laws affecting creditors' rights generally and to general principles of equity, regardless of whether considered in a proceeding in equity or at law) and (c) the execution, delivery and performance of this Agreement by the Company does not and will not (i) violate or conflict with any law, rule, regulation, order, judgment or decree applicable to the Company, or (ii) result in any breach or violation of or constitute a default (or an event which with notice or lapse of time or both would result in or constitute such a breach, violation or default) under or pursuant to, or result in the loss of a material benefit under, or give any right of termination, amendment, acceleration or cancellation of, any organizational document, agreement, contract, commitment, understanding or arrangement to which the Company is a party or by which it is bound.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.<u>Term.</u> Except as otherwise set forth herein, the term of this Agreement (the "<u>Term</u>") shall commence on the Effective Date and shall continue until the earlier of (a) the date (the "<u>Expiration Date</u>") that is fifteen (15) business days prior to the deadline under the Company's Amended and Restated Bylaws for the submission of director nominations and stockholder proposals for the Company's 2027 annual meeting of stockholders and (b) the termination of this Agreement in accordance with its terms; <u>provided</u>, that (i) Mill Road may terminate this Agreement prior to the Expiration Date only if the Company commits a material breach of its obligations under this Agreement or the Board Observer Agreement that, in each case (if capable of being cured), is not cured within fifteen (15) days after receipt by the Company of written notice from Mill Road or the Observer specifying the material breach in reasonable detail, and (iii) the Company may terminate this Agreement prior to the Expiration Date only if Mill Road or the Observer commits a material breach of this Agreement or the Board Observer Agreement, respectively, that, in each case (if capable of being cured), is not cured within fifteen (15) days after receipt by Mill Road or the Observer, as applicable, of written notice from the Company specifying the material breach in reasonable detail; <u>provided further</u> that no expiration or termination of this Agreement will relieve any Party hereto from any liability for a breach of this Agreement prior to such expiration or termination.

Each Party agrees to waive any bonding requirement under any applicable law in the case any other Party seeks to enforce the terms by way of equitable relief.

**Exhibit 99.1**

**Alta Equipment Group Announces Board Observer**

**LIVONIA, Mich. – January 22, 2026** – Alta Equipment Group Inc.
