Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

Item 6 of the Original Schedule 13D is hereby amended and restated as follows:

On April 1, 2024, the Issuer, AdTheorent Holding Company, Inc., a Delaware corporation (the “Issuer”), Cadent, LLC, a Delaware limited liability company (“Parent”), Award Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Parent (“Merger Sub”), Novacap Cadent Acquisition Company, Inc. and Novacap Cadent Holdings, Inc. entered into an Agreement and Plan of Merger (as it may be amended from time to time, the “Merger Agreement”), which provides, among other things, for the merger of Merger Sub with and into the Issuer (the “Merger”), with the Issuer surviving the Merger as a wholly owned subsidiary of Parent, upon the terms and subject to the conditions set forth in the Merger Agreement. As a result of the Merger, the Reporting Persons will cease to beneficially own shares of the Issuer, the Issuer will become a privately held company, the Stockholders Agreement will terminate, and the directors nominated by H.I.G. AdTheorent to the Board will resign from the Board at the effective time of the Merger.

Voting and Support Agreement

On April 1, 2024, in connection with the execution of the Merger Agreement, Issuer, H.I.G. AdTheorent, Merger Sub and Parent entered into a voting and support agreement (the “Voting and Support Agreement”). Pursuant to the Voting and Support Agreement, H.I.G. AdTheorent has agreed to vote in favor of (i) the adoption of the Merger Agreement and (ii) the approval of any proposal to adjourn or postpone to a later date the meeting of the Issuer’s stockholders to adopt the Merger Agreement (the “Stockholders’ Meeting”) if there are not sufficient votes to adopt the Merger Agreement. In addition, H.I.G. AdTheorent has agreed to vote against (i) any action or proposal in favor of an alternative acquisition proposal from a third party, (ii) any action or proposal that could reasonably be expected to result in a breach of any covenant, representation or warranty, or any other obligation or agreement of the Company under the Merger Agreement or of H.I.G. AdTheorent under the Voting and Support Agreement, and (iii) any action, proposal, transaction or agreement that would reasonably be expected to impede, interfere with, delay, discourage, adversely affect or inhibit the timely consummation of the Merger or the fulfillment of Parent’s, the Issuer’s or Merger Sub’s conditions to closing under the Merger Agreement or change in any manner the voting rights of any shares of the Company.

While the Voting and Support Agreement is in effect, certain transfers of shares of Common Stock by H.I.G. AdTheorent are restricted.

Pursuant to the Voting and Support Agreement, in connection with the execution the Merger Agreement, immediately prior to, and conditioned upon the Effective Time of the Merger Agreement (as defined in the Merger Agreement), H.I.G. AdTheorent agreed to forfeit 1,167,308 shares of Common Stock to the Issuer for cancellation (the “Forfeiture”). The Issuer and H.I.G. AdTheorent agreed that the Forfeiture shall be treated as a nontaxable contribution to the capital of the Issuer by H.I.G. AdTheorent, and neither H.I.G. AdTheorent nor the Issuer shall take any position inconsistent with such treatment unless otherwise required under the Internal Revenue Code of 1986, as amended.

Subject to the exceptions set forth in the Voting and Support Agreement, the obligations of H.I.G. AdTheorent under the Voting and Support Agreement terminate on the earliest of (i) the valid termination of the Merger Agreement pursuant to Article 8 thereof, (ii) the Effective Time of the Merger Agreement (as defined in the Merger Agreement), and (iii) the termination of the Voting and Support Agreement by mutual written consent of the parties thereto. Notwithstanding anything to the contrary, in the event the Issuer’s board of directors validly makes an Adverse Recommendation Change (as defined in the Merger Agreement), the Voting and Support Agreement will not be terminated, but the number of shares of Company Common Stock to which the support obligations apply under the Voting and Support Agreement will be reduced to 35% of the outstanding shares of Common Stock.

The foregoing description of the Voting and Support Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of such agreement, which is attached as an exhibit hereto and incorporated herein by reference.
