Capitalized terms used herein and not otherwise defined have the meanings ascribed to them in paragraph 13 below.

Mr. Calderoni will be the initial Chair of the Strategy Committee. The initial charter of the Strategy Committee will be in the form attached to this Agreement as Exhibit A (the “Strategy Committee Charter”), and any proposed change to the Strategy Committee Charter will require the prior written consent of the Investors (such consent not to be unreasonably withheld, conditioned or delayed).

Effective upon the appointment of any such replacement member to such committee, such replacement member will be considered a New Director solely for the purposes of this paragraph 2(d).

Each of the Investors represents, warrants and agrees that neither it nor any of its Affiliates (as defined below) (a) has paid or will pay any compensation to any New Director (including replacement candidates contemplated by paragraph 4) relating to or regarding such person’s service on the Board or any committee thereof or (b) has or will have any agreement, arrangement or understanding, written or oral, with any New Director (including replacement candidates contemplated by paragraph 4) regarding such person’s service on the Board or

any committee thereof (for the avoidance of doubt, in the case of an Investor Director, excluding ordinary course employment agreements or arrangements with any of the Investors or their Affiliates).

4.2026 Annual Meeting; Replacements.

(a)The Company shall include any New Director as a director nominee on its slate for election at the 2026 Annual Meeting, subject to paragraph 7. In connection with the 2026 Annual Meeting (and any adjournments or postponements thereof), the Company will recommend that the Company’s stockholders vote in favor of the election of each of the Board’s nominees, use commercially reasonable efforts to solicit proxies for each of the Board’s nominees, and cause all Common Stock (as defined below) represented by proxies granted to it (or any of its officers, directors or representatives) to be voted in favor of each of the Board’s nominees (in each case, including any New Director). Notwithstanding the foregoing, the Company’s obligations under this paragraph 4(a) shall only apply to an Investor Director if the Investors deliver written notice to the Company of their exercise of their right to the appointment of an Investor Director to the Board pursuant to paragraph 1(b) on or prior to the 75th day prior to the first anniversary of the Company’s 2025 annual meeting of stockholders.

(b)If (x) any New Director is unable or unwilling to serve as a director, resigns as a director, is removed as a director or ceases to be a director for any other reason prior to the Expiration Date, and (y) at such time the Investors beneficially own a “net long position” of, or have aggregate net long economic exposure to, at least 2.0% of the Company’s outstanding Common Stock (the “Minimum Ownership Threshold”), the Investors shall be entitled to select, in consultation with the Company and as approved by the Board (such approval not to be unreasonably withheld, conditioned or delayed, and with respect to a replacement for an Investor Director, such approval not to be withheld, conditioned or delayed on the basis that such person is an employee of an Investor or an Affiliate of an Investor), a substitute who is Independent (as defined below) and satisfies the Board membership criteria set forth in the Governance Guidelines (a “Replacement New Director”), and the Board shall take such actions as are necessary to appoint the Replacement New Director to serve as a director of the Company for the remainder of such New Director’s term. Effective upon the appointment of the Replacement New Director to the Board, such Replacement New Director will be considered a New Director (with any replacement for an Investor Director considered an Investor Director) for all purposes of this Agreement from and after such appointment.

(c)The Company’s obligations under paragraphs 1 to 4 shall terminate prior to the Expiration Date (i) if the Investors cease to satisfy the Minimum Ownership Threshold, (ii) if any Investor breaches in any material respect any of the terms of this Agreement and such breach has not been cured within five business days’ written notice by the Company to the Investors of such breach, provided that the Company is not in material breach of this Agreement at the time such notice is given or prior to the end of the notice period, (iii) upon such time as the Investor Director notifies the Company of his or her intent to resign from the Board and the Investors irrevocably waive in writing any right to have a Replacement New Director for the Investor Director appointed, or (iv) if any of the Investors or any other Restricted Person (as defined below) submits any director nomination for election at any meeting of the Company’s stockholders. Upon the occurrence of an event described in clause (iv) of this paragraph 4(c), an Investor Director shall

promptly offer to resign from the Board (and, if requested by the Company, promptly deliver his or her written resignation to the Board for his or her immediate resignation), subject to the Board’s decision in its sole discretion whether to accept or reject such resignation. The Investors agree to cause, and agree to cause their respective Affiliates to cause, an Investor Director (including any Replacement New Director for an Investor Director) to resign from the Board if he or she fails to resign if and when requested by the Company pursuant to this paragraph 4(c).

5.New Director Information. The Company acknowledges that Mr. Calderoni has provided to the Company, at the Company’s request, information required to be disclosed in a proxy statement or other filing under applicable law, stock exchange rules or listing standards, and information in connection with assessing eligibility, independence and other criteria applicable to directors or satisfying compliance or legal obligations (including authorization with respect to background checks), in each case, consistent with the information and background checks required by the Company in accordance with past practice with respect to other non-management members of the Board (collectively, the “New Director Information”), and the Board has relied upon such New Director Information being accurate and complete in all material respects. As a condition to any Investor Director’s or Replacement New Director’s appointment to the Board, or any subsequent nomination of any New Director for election as a director at the Company’s Annual Meeting of Stockholders, such person will provide any information the Company reasonably requires, including information required to be disclosed in a proxy statement or other filing under applicable law, stock exchange rules or listing standards, information in connection with assessing eligibility, independence and other criteria applicable to directors or satisfying compliance and legal obligations, and will consent to reasonable and customary background checks, to the extent, in each case, consistent with the information and background checks required by the Company in accordance with past practice with respect to other non-management members of the Board.

6.Voting of Investors’ Shares. In connection with the 2026 Annual Meeting (and any adjournments or postponements thereof), so long as each New Director has been nominated by the Board for re-election as a director in accordance with paragraph 4(a), the Investors will cause to be present in person or by proxy for quorum purposes and will vote or cause to be voted all of the Common Stock for which they or such controlling or controlled Affiliates have the right to vote (or to direct be voted) on the record date for the 2026 Annual Meeting in favor of (a) the election of each of the Board’s nominees (including any New Director) and (b) otherwise in accordance with the Board’s recommendation on any other nomination or proposal; provided that the Investors shall be permitted to vote in their sole discretion on any proposal related to an Extraordinary Transaction (as defined below); provided further, that in the event that both Institutional Shareholder Services and Glass Lewis & Co. (including any successors thereof) issue a voting recommendation that differs from the voting recommendation of the Board with respect to any Company-sponsored proposal submitted to stockholders at a stockholder meeting (other than with respect to the election of directors to the Board, the removal of directors from the Board, the size of the Board or the filling of vacancies on the Board), the Investors and their Affiliates shall be permitted to vote in accordance with any such recommendation.

7.Company Policies. The parties hereto acknowledge that any New Director, upon election or appointment to the Board, will serve as a member of the Board and will be governed by the same protections and obligations regarding confidentiality, conflicts of interest, related party transactions, fiduciary duties, codes of conduct, trading and disclosure policies, director resignation policy, and other governance guidelines and policies of the

Company as other directors (collectively, the “Company Policies”), and shall have the same rights and benefits, including with respect to insurance, indemnification, compensation and fees, as are applicable to all non-employee directors of the Company. The Company represents and warrants that all Company Policies currently in effect are publicly available on the Company’s website or have otherwise been provided in writing to the Investors. The Company acknowledges and agrees that (i) no Company Policy shall in any way inhibit any Board members (including any New Director) from communicating with the Investors so long as they comply with applicable law, their confidentiality obligations to the Company, their fiduciary duties to the Company and the Governance Guidelines in their capacity as Board members, (ii) no Company Policy shall be violated by an Investor Director receiving indemnification and/or reimbursement of expenses from the Investors or their respective Affiliates solely in connection with his or her service or action as an employee of an Investor or an Affiliate of an Investor (and not in connection with his or her service or action as a director of the Company), and (iii) no Company Policy shall apply to the Investors and their Affiliates, including Company Policies with respect to trading in the Company’s securities, as the Investors and their Affiliates are not directors or employees of the Company.

8.Standstill. During the period starting on the date of this Agreement until the Expiration Date (such period, the “Cooperation Period”), each Investor will not, and will cause its controlling and controlled (and under common control) Affiliates and its and their respective representatives acting on their behalf (collectively with the Investors, the “Restricted Persons”) to not, directly or indirectly, without the prior consent, invitation, or authorization by the Company or the Board, in each case, in writing:
