On July 19, 2026, Conversant PIF Aggregator A LP, a Delaware limited partnership and an affiliate of the Reporting Persons ("Aggregator"), entered into a subscription agreement (the "Subscription Agreement") with the Issuer, pursuant to which Aggregator agreed that it or its permitted assignee would purchase, and pursuant to which Purchaser, as the permitted assignee of Aggregator, purchased 3,479,532 shares (the "Shares") of Class A Common Stock, at a price per share of $1.71, for an aggregate purchase price of approximately $5,950,000, in a private placement (the "Private Placement"). Purchaser satisfied its funding obligations to the Issuer arising under the Subscription Agreement with amounts contributed by its feeder funds (the "Feeders"), which amounts were called by those Feeders from the pre-existing capital obligations of their existing limited partners.

The information reported in Item 3 of this Schedule 13D is incorporated by reference into this Item 4. As described in more detail in Item 6, below, under the caption "Board Appointment Rights," Purchaser obtained certain rights to nominate a member of Issuer's board of directors (the "Board"). Pursuant to such rights, Purchaser nominated Jacky Wu to the Board, and the Board in turn elected Mr. Wu as a member with effect from the closing of the Private Placement. Mr. Wu is not otherwise associated with the Reporting Persons and is independent of the Company's management. The Reporting Persons intend to participate in the management of the Issuer in the ordinary course of business and consistent with the extent of its investment, for example by participating in discussions with members of the Issuer's board of directors, management, and other Issuer investors regarding the Issuer's business, including its operations, prospects, capitalization and corporate governance. The information set forth under "Board Appointment Rights" in Item 6 hereof is incorporated by reference into this Item 4. Pursuant to the Subscription Agreement, Purchaser has been granted certain preemptive and registration rights with respect to the Issuer's securities. For further information see the information set forth under "Preemptive Rights" and "Registration Rights" in Item 6 hereof, which is incorporated by reference into this Item 4. Purchaser has certain rights to dispose of Shares to the Issuer in connection with certain Issuer repurchases, redemptions, retirements or other acquisitions of Class A Common Stock (or other Issuer voting securities). See the information set forth under "Ownership Threshold Protection" in Item 6 hereof, which is incorporated by reference into this Item 4. Except as set forth herein and to the extent that the Reporting Persons may have influence over the corporate activities of the Issuer on the basis of the relationships, rights and plans described above, including activities that may relate to the items described in subparagraphs (a) through (j) of Item 4 of Schedule 13D, the Reporting Persons do not have any present plans or proposals that relate to or would result in any of the matters set forth in subparagraphs (a) through (j) of Item 4 of Schedule 13D. The Reporting Persons reserve the right to increase or decrease their position in the Issuer through, among other things, the purchase or sale of securities of the Issuer on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable. The Reporting Persons reserve the right to change their intention with respect to any and all matters referred to in this Item 4.

Board Appointment Rights. Pursuant to the Subscription Agreement, effective at the Closing Date, and for so long as Purchaser beneficially owns at least 5.0% of the outstanding shares of Class A Common Stock, the Issuer shall take all actions necessary to cause one (1) individual (the "Purchaser Director") nominated by the Purchaser to be elected or appointed to the Board, subject to meeting certain independence requirements and the consent of the Issuer and two other investors of the Issuer, each as set forth in the Subscription Agreement. If Purchaser nominates an individual who does not satisfy certain heightened independence requirements set forth in the Subscription Agreement, the Issuer has agreed to use commercially reasonable efforts, following receipt of certain required regulatory approvals and subject to applicable law, Nasdaq listing requirements and the approval of the Board and the nominating and governance committee of the Issuer, to appoint such individual to the Board or nominate such individual for election at the next meeting of Issuer stockholders at which directors are elected. Purchaser's initial nominee, Jacky Wu, was appointed to the Board at the closing of the Private Placement. Voting Commitment. For so long as the Purchaser Director is serving as a member of the Board, Purchaser has agreed with the Issuer that it will, and will cause its affiliates to, cause all shares of Class A Common Stock beneficially owned by Purchaser and its affiliates to be voted in favor of the election of each member of any slate of directors recommended by the Board that includes all director nominees designated by Purchaser pursuant to the Subscription Agreement; provided that the Purchaser Director shall have voted in favor of such slate. Preemptive Rights. Pursuant to the Subscription Agreement, until the earliest of (i) the third (3rd) anniversary of the closing of the Private Placement, (ii) the time when Purchaser and its affiliates beneficially own less than 3.0% of the shares of Class A Common Stock acquired pursuant to the Subscription Agreement, and (iii) a change of control of the Issuer, subject to certain customary exceptions, Purchaser shall have a preemptive right pursuant to which Purchaser may purchase for cash, on the same terms and conditions as offered to other investors, a pro rata portion of certain future issuances by the Issuer of equity securities or securities convertible into, exercisable for or exchangeable for equity securities, based on Purchaser's beneficial ownership of the Issuer's then-outstanding Class A Common Stock on a fully diluted basis. Registration Rights. Beginning on the first (1st) anniversary of the closing date of the Private Placement, subject to certain customary exceptions and otherwise on customary terms and conditions, including that the Issuer shall bear the costs and expenses in connection with any shelf registration statement up to $15,000 (subject to certain exceptions), Purchaser will have the right to request that the Issuer prepare and file a shelf registration statement covering the resale of all registrable securities then outstanding or issuable pursuant to the Subscription Agreement, and the Issuer will be required to file such shelf registration statement within sixty (60) days following receipt of such request and use its reasonable best efforts to cause such registration statement to be declared effective by the SEC as soon as practicable thereafter. In addition, beginning on the first (1st) anniversary of the closing date of the Private Placement, Purchaser will have customary piggyback registration rights in connection with certain registrations of the Issuer's securities. Notwithstanding the foregoing, if any of Purchaser's applications seeking certain regulatory approvals are rejected or otherwise declined by the applicable governmental authority, Purchaser shall thereafter have the right to deliver a request for registration at any time. Ownership Threshold Protection. For so long as Purchaser or its affiliates beneficially own any voting securities of the Issuer, prior to consummating certain repurchases, redemptions, retirements or other acquisitions of voting securities that would result in Purchaser and its affiliates beneficially owning more than 9.9% of the Issuer's outstanding voting securities, the Issuer shall use commercially reasonable efforts to provide Purchaser with prior notice of such transaction. Following receipt of such notice, Purchaser will have the right to request that the Issuer repurchase from Purchaser or its affiliates a sufficient number of voting securities at the Per Share Purchase Price (as defined in the Subscription Agreement) to prevent Purchaser and its affiliates from exceeding such ownership threshold, subject to applicable law, the Issuer's organizational documents and the Issuer's financing arrangements. If Purchaser does not timely request such repurchase, or if the Issuer is unable to complete such repurchase, Purchaser has agreed that it will not vote any shares held by it or its affiliates in excess of the 9.9% ownership threshold until such time as its beneficial ownership percentage no longer exceeds such threshold; provided that such shares will continue to retain their economic rights, including rights to dividends and distributions.
