Shares beneficially owned by the Stockholder Parties, other than by Capitol, are not the subject of this Schedule 13D and accordingly, none of the other Stockholder Parties is included as a reporting person. For a description of the relationship between the Reporting Persons and the other Stockholder Parties, see Item 4 below.

During the last five years, none of the Reporting Persons (i) has been convicted in any criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) was a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

(“CIC”), the predecessor in interest to the Issuer, Capitol purchased 10,062,500 Class B ordinary shares of CIC for an aggregate purchase price of $25,000, or approximately $0.0025 per share (the “Founder Shares”) and in connection with such initial public offering purchased warrants to purchase 6,533,333 Class A ordinary shares of CIC for an aggregate purchase price of approximately $9.8 million, or $1.50 per warrant. Directors and team members owned 182,500 Class B ordinary shares and 399,999 warrants.

Item 4.

Purpose of Transaction.

Amended and Restated Stockholders’ Agreement

On April 1, 2021 (the “Closing Date”), in connection with the closing of the acquisition (the “Acquisition”) of 100% of the partnership interests of Custom Truck One Source, L.P. by a wholly owned subsidiary of the Issuer, the Issuer and the Stockholder Parties entered into an Amended and Restated Stockholders’ Agreement (the “Amended and Restated Stockholders’ Agreement”).

The Amended and Restated Stockholders’ Agreement provides that Platinum will have the right to designate up to seven nominees for the election to the Issuer’s Board of Directors (the “Board”), three of which are required to be independent directors. Each Platinum designee director who is not an independent director will have two votes on the Board. For so long as Platinum beneficially owns less than 50% but more than 30% of the Common Stock, Platinum will have the right (but not the obligation) to designate any number of directors, who are not independent directors, having one or two votes each, so long as the total number of votes of all such designees does not exceed the difference of the total number of votes constituting a majority of all votes of all directors minus one. The number of designees who are not independent directors that Platinum is entitled to nominate decreases from four to one, and such director’s voting power decreases to one vote, if Platinum beneficially owns less than 30% but more than 4.5% of the Common Stock. All such rights to designate nominees, including independent directors, shall cease if Platinum fails to beneficially own more than 4.5% of the Common Stock.


CUSIP No. 64083J 104		13D		Page 7 of 11 Pages

The Amended and Restated Stockholders’ Agreement further provides that (i) each of Blackstone and ECP will have the right to designate one nominee for the election to the Board so long as such investor beneficially owns at least 4.5% of the Common Stock, (ii) Capitol will have the right to designate one nominee for the election to the Board so long as it beneficially owns at least 50% the Common Stock it held as of the Closing Date and (iii) the chief executive officer of the Issuer shall hold a seat on the Board.

If, at any time while Platinum beneficially owns more than 50% of the Common Stock, Platinum receives a bona fide offer from a third party to purchase or otherwise desires to transfer shares of Common Stock to a third party on arm’s length terms including shares of Common Stock owned by Blackstone, ECP, Capitol or certain members of management of the Issuer (the “Drag Shares”), and (i) such sale proposal, if consummated, would result in a change in control of the Issuer (taking into account all Drag Shares), (ii) such sale proposal does not involve the transfer of Drag Shares to Platinum or an affiliate of Platinum and (iii) in such sale proposal, if consummated, Platinum would receive the same form of consideration as the other stockholders in the Issuer (a “Required Sale”), then Platinum may deliver a written notice with respect to such Sale Proposal at least ten business days prior to the anticipated closing date of such Required Sale to Blackstone, ECP, Capitol and the applicable members of the Issuer’s management requiring them to sell or otherwise transfer their shares of Common Stock to the proposed transferee.

In the event of one or multiple follow-on offerings that close at or above the Trigger Price during the Lockup Period, for the first $200 million of aggregate proceeds sold (the “First Tranche”), each Qualifying Shareholder, alongside Platinum, shall have the right to sell up to one third of the First Tranche (Platinum and each Qualifying Shareholder may sell proportionally more to the extent a Qualifying Shareholder doesn’t participate in such transaction up to a third). Capitol will have the right to participate alongside ECP (on a pro rata basis) within ECP’s allocable portion of the First Tranche. For any amount raised at or above the Trigger Price in addition to the First Tranche during the Lockup Period, Platinum, Capitol and each Qualifying Shareholder shall participate on a pro rata basis.

In addition, the Amended and Restated Stockholders’ Agreement gives Platinum, ECP, Capitol and Blackstone certain short-form, demand and piggyback registration rights with respect to the shares of Common Stock held by them, subject to certain conditions set forth therein.

The foregoing description of the Amended and Restated Stockholders’ Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of such agreement filed as an exhibit to this Schedule 13D and incorporated herein by reference.

General

The Reporting Persons acquired the securities described in this Schedule 13D for investment purposes and intend to review their investments in the Issuer on a continuing basis. Any actions the Reporting Persons might undertake may be made at any time and from time to time without prior notice and will be dependent upon the Reporting Persons’ review of numerous factors, including, but not limited to: an ongoing evaluation of the Issuer’s business, financial condition, operations and prospects; price levels of the Issuer’s securities; general market, industry and economic conditions; the relative attractiveness of alternative business and investment opportunities; and other future developments.


CUSIP No. 64083J 104		13D		Page 8 of 11 Pages

Subject to the terms of the Amended and Restated Stockholders’ Agreement, the Reporting Persons may acquire additional securities of the Issuer, or retain or sell all or a portion of the securities then held, in the open market or in privately negotiated transactions. In addition, the Reporting Persons and their designee to the Board may engage in discussions with management, the Board, and securityholders of the Issuer and other relevant parties or encourage, cause or seek to cause the Issuer or such persons to consider or explore extraordinary corporate transactions, such as: a merger, reorganization or other transaction that could result in the de-listing or de-registration of the Common Stock; sales or acquisitions of assets or businesses; changes to the capitalization or distribution policy of the Issuer; or other material changes to the Issuer’s business or corporate structure, including changes in management or the composition of the Board. There can be no assurance, however, that any Reporting Person will propose such a transaction, that any proposed transaction would receive the requisite approvals from the respective governing bodies and unitholders, as applicable, or that any such transaction would be successfully implemented.

Other than as described above, the Reporting Persons do not currently have any plans or proposals that relate to, or would result in, any of the matters listed in Items 4(a)–(j) of Schedule 13D, although, depending on the factors discussed herein, the Reporting Persons may change their purpose or formulate different plans or proposals with respect thereto at any time.
