Each of Jabbok Schlacks and William J. Schlacks IV is a Managing Member of EQS Heritage Holdings LLC and EQS Legacy Holdings LLC and has controlling voting and dispositive power with regard to the shares held by such entities. Each share of Class B Common Stock is convertible into one share of the Issuer's Class A Common Stock at any time at the option of the holder thereof. Jabbok Schlacks and William J. Schlacks IV are parties to a voting agreement whereby each has agreed to vote their shares together as a group. Accordingly, each of Jabbok Schlacks and William J. Schlacks IV may be deemed to beneficially own each other's stock with shared voting power, currently consisting in the aggregate of 100,000 shares of Class A Common Stock and 37,568,944 shares of Class B Common Stock. Notes to row 13: (2) Based on the quotient obtained by dividing (a) the aggregate number of Class A Common Stock and Class B Common Stock, together, beneficially owned by the Reporting Person as set forth in Row 11 by (b) the sum of (i) 214,806,153 shares of Class A Common Stock outstanding as of May 10, 2026 and (ii) the aggregate number of shares of Class B Common Stock beneficially owned by the Reporting Person. The aggregate number of shares of Class B Common Stock beneficially owned by the Reporting Person as set forth in clauses "(a)" and "(b)" of this footnote are treated as converted into shares of Class A Common Stock solely for the purpose of computing the percentage ownership of the Reporting Person. (3) Each share of Class A Common Stock is entitled to one vote and each share of Class B Common Stock is entitled to 20 votes. Accordingly, each of Jabbok Schlacks and William J. Schlacks IV own 42.5% of the total outstanding voting power, and based on their voting agreement, their interests collectively represent 81% of the aggregate voting power of the Issuer's issued and outstanding share capital.

Exhibit 2

 

 

VOTING AGREEMENT

 

VOTING AGREEMENT (the “Agreement”), dated as of January 22, 2026 between Jabbok Schlacks, a natural person (“JS”), and William J. Schlacks IV, a natural person (“WS”). Each of JS and WS are referred to herein individually as a “Founder” and together, the “Founders”. Reference is made to that certain Amended and Restated Certificate of Formation of EquipmentShare.com Inc (the “Corporation”) to be dated as of or around January 26, 2026 (as amended from time to time, the “Charter”). Capitalized terms used but undefined herein shall have the meaning ascribed to such terms in the Charter.

 

WHEREAS, JS and WS are the beneficial owners of shares of the Corporation’s Common Stock (the “Founder Shares”); and

 

WHEREAS, in connection with the Corporation’s initial public offering, the Founders have agreed to provide for the future voting of the Founder Shares and any other shares of the Corporation’s capital stock held by or on behalf of the Founders (collectively, the “Founder Shares”) as set forth below.

 

NOW, THEREFORE, in consideration of these premises and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Founders agree as follows:

 

Article 1
Voting Agreement

 

Section 1.01. Voting Agreement.  

 

(a)       Each Founder hereby agrees to vote or exercise their respective rights to consent with respect to all Founder Shares that such Founder is entitled to vote at the time that any vote or action by written consent is sought with respect to any matter submitted for the consideration and vote of the stockholders of the Corporation (each, a “Stockholder Vote”) together with, and in the same manner as, the other Founder as mutually agreed by them. For clarity, for so long as this Agreement remains in effect, to the extent any Founder Share is voted, in accordance with the mutual agreement of the Founders, either “For”/”Yes” or “Against”/“No” in respect of any matter for which a Stockholder Vote applies, then all Founder Shares shall be voted in an identical manner; provided, that nothing herein shall be construed to require the Founders to vote either “For”/”Yes” or “Against”/“No” in respect of any particular Stockholder Vote so long as all Founder Shares are voted together.

 

(b)       Each Founder agrees that all Founder Shares registered in his name or beneficially owned by him (including any shares of the Corporation’s capital stock held by any trust formed solely for the benefit of such Founder or such Founder’s family members, any partnership, corporation, foundation, charity or other entity, so long as such Founder controls such trust, partnership, corporation, foundation, charity or other entity) as of the date hereof, and any such Founder Shares acquired by such Founder after the date hereof, will be subject to, and voted in accordance with, Section 1.01(a).

 

(c)       Each Founder shall not, without the prior written consent of the other Founder, directly or indirectly, grant any proxies or enter into any voting trust or other agreement or arrangement with respect to the voting of any Founder Shares to the extent such voting trust, other agreement or arrangement would be inconsistent with the agreements set forth in Section 1.01(a).
