Item 6 of the Amended Schedule 13D is hereby further supplemented and amended to add the following information: Consummation of Up-C Collapse On November 3, 2025, the Issuer and the Predecessor Issuer consummated the Up-C Collapse. As part of the Up-C Collapse, the Predecessor Issuer implemented a holding company reorganization (the "Holding Company Reorganization") pursuant to an Agreement and Plan of Merger (the "Pubco Merger Agreement"), dated as of November 3, 2025, among the Predecessor Issuer, the Issuer and Bakkt Merger Sub 1, Inc., a Delaware corporation and wholly owned subsidiary of the Issuer ("Merger Sub 1"), pursuant to which Merger Sub 1 merged with and into the Predecessor Issuer (the "Pubco Merger"), and which resulted in the Issuer becoming the direct parent company of the Predecessor Issuer and replacing the Predecessor Issuer as the public company trading on the New York Stock Exchange. Immediately after the Holding Company Reorganization, as part of the Up-C Collapse, pursuant to an Agreement and Plan of Merger (the "Opco Merger Agreement"), dated as of November 3, 2025, among the Issuer, Bakkt Opco Holdings, LLC, a Delaware limited liability company ("Bakkt Opco"), Bakkt Management LLC, a Delaware limited liability company ("Bakkt Management"), and Bakkt Merger Sub 2, LLC, a Delaware limited liability company and wholly owned subsidiary of the Issuer ("Merger Sub 2"), Merger Sub 2 merged with and into Bakkt Opco (the "Opco Merger"), which resulted in the Issuer directly and indirectly wholly owning Bakkt Opco. In accordance with the Pubco Merger Agreement, (i) each share of Class A common stock, par value $0.0001 per share (the "Class A Common Stock"), of the Predecessor Issuer issued and outstanding immediately prior to the effective time of the Holding Company Reorganization (the "Holding Company Reorganization Effective Time"), including each of the 649,934 shares of Class A Common Stock owned by ICEH, was converted automatically into the right to receive one share of New Class A Common Stock, and (ii) each share of Class V common stock, par value $0.0001 per share (the "Class V Common Stock"), of the Predecessor Issuer issued and outstanding immediately prior to the Holding Company Reorganization Effective Time, including each of the 6,803,178 shares of Class V Common Stock owned by ICEH, was converted automatically into the right to receive one share of Class V common stock, par value $0.0001 per share ("New Class V Common Stock"), of the Issuer. Accordingly, upon consummation of the Holding Company Reorganization, stockholders of the Predecessor Issuer (including ICEH) automatically became stockholders of the Issuer, on a one-for-one basis. In accordance with the terms of the Opco Merger Agreement and the Amended and Restated Exchange Agreement, (i) each outstanding common unit of Bakkt Opco ("Bakkt Opco Common Unit") (excluding any Opco Incentive Unit (as defined below) and any Bakkt Opco Common Unit owned by the Predecessor Issuer), together with one share of New Class V Common Stock paired therewith (a "Paired Interest"), issued and outstanding immediately prior to the effective time of the Opco Merger (the "Opco Merger Effective Time"), including each of the 6,803,178 Paired Interests owned by ICEH, was exchanged for the right to receive one share of New Class A Common Stock, resulting in the elimination of the shares of New Class V Common Stock and the Issuer having only a single class of common stock outstanding (the New Class A Common Stock), (ii) each member's membership unit of Bakkt Management issued and outstanding immediately prior to the Opco Merger Effective Time was exchanged for the corresponding common unit of Bakkt Opco (each such unit, an "Opco Incentive Unit") granted under the Second Amended and Restated Bakkt Equity Incentive Plan, as amended, held by Bakkt Management, together with the share of New Class V Common Stock paired therewith, and (iii) each Opco Incentive Unit, together with the share of New Class V Common Stock paired therewith, issued and outstanding immediately prior to the Opco Merger Effective Time was exchanged for the right to receive one share of New Class A Common Stock. Replacement of Acquired Warrants In connection with the Holding Company Reorganization, (i) each of the Predecessor Issuer's Class 1 Warrants to purchase shares of Class A Common Stock that was outstanding and unexercised prior to the Holding Company Reorganization Effective Time, including two of the four Acquired Warrants issued to ICEH, was exchanged for an equivalent warrant to purchase shares of New Class A Common Stock (the "Replacement Class 1 Warrants") and (ii) each of the Predecessor Issuer's Class 2 Warrants to purchase shares of Class A Common Stock that was outstanding and unexercised prior to the Holding Company Reorganization Effective Time, including the other two of the four Acquired Warrants issued to ICEH, was exchanged for an equivalent warrant to purchase shares of New Class A Common Stock (the "Replacement Class 2 Warrants", and together with the Replacement Class 1 Warrants, the "Replacement Warrants"). The foregoing description of the Replacement Warrants is qualified in its entirety by reference to the descriptions of the Acquired Warrants in Amendment No. 3 and Amendment No. 4 and the full text of the Replacement Warrants, which are filed as Exhibits 99.27, 99.28, 99.29 and 99.30 to the Amended Schedule 13D and incorporated herein by reference. Contribution Agreement Amendment and Convertible Preferred Stock Immediately prior to the consummation of the Up-C Collapse, the Predecessor Issuer, Mr. Naheta, and ICEH entered into an amendment (the "Contribution Agreement Amendment") to the Contribution Agreement pursuant to which they agreed that after ICEH and Mr. Naheta would contribute their rights under the Tax Receivable Agreement to the Issuer in exchange for cash, (i) Mr. Naheta would further contribute such cash payable to Mr. Naheta to the Issuer in exchange for shares of New Class A Common Stock, as contemplated by the Contribution Agreement prior to the Contribution Agreement Amendment, but (ii) ICEH would further contribute such cash payable to ICEH to the Issuer in exchange for shares of Series A Non-Voting Convertible Preferred Stock, par value $0.0001 per share ("Convertible Preferred Stock"), of the Issuer (rather than shares of New Class A Common Stock, as contemplated by the Contribution Agreement prior to the Contribution Agreement Amendment). In connection with the arrangements under the Tax Receivable Agreement and the Contribution Agreement, each as amended, upon the consummation of the Up-C Collapse on November 3, 2025, the Issuer issued 465,890 shares of Convertible Preferred Stock to ICEH, at a price per share equal to $39.34, representing the "Minimum Price" as defined in NYSE Rule 312.04(h), which was offset against the aggregate $18,328,117 cash payment to which ICEH was otherwise entitled under the Tax Receivable Agreement, as amended. Each share of Convertible Preferred Stock is convertible into one share of New Class A Common Stock upon the earlier of (i) the expiration or termination of the waiting period applicable to such conversion under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act"), or (ii) a direct transfer of such share to an unaffiliated third party of ICEH. Prior to conversion, shares of Convertible Preferred Stock are entitled to dividends in the same form, and in the same manner, as dividends actually paid (if any) on shares of New Class A Common Stock and are entitled to participate on an as-converted-to-New Class A Common Stock basis in any liquidation, dissolution or winding up of the Issuer or in any consolidation, merger or reorganization of the Issuer into or with any other entity. The number of shares of New Class A Common Stock into which the Convertible Preferred Stock is convertible is subject to customary antidilution adjustments. The Convertible Preferred Stock does not have voting rights. The foregoing descriptions of the Contribution Agreement Amendment and the Convertible Preferred Stock are qualified in their entirety by reference to the full text of the Contribution Agreement Amendment and the Certificate of Designation for the Convertible Preferred Stock, which are filed as Exhibit 99.31 to the Amended Schedule 13D and incorporated herein by reference.
