Item 6.

Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer

The information contained in Item 6 of the Schedule 13D is hereby amended and supplemented by adding the following information: On April 3, 2026, IAC entered into a Voting Agreement (the "Voting Agreement") with the Issuer and Barry Diller. Pursuant to the Voting Agreement, at any time a matter is brought to a vote at an annual or special meeting of the Issuer's stockholders (or in connection with any action proposed to be taken by the Issuer's stockholders in lieu of a meeting), IAC, Mr. Diller and their respective controlled affiliates (collectively the "Covered Entities") will vote any voting securities that they beneficially own that collectively constitute in excess of 25.73% of the total voting power of the outstanding voting securities of the Issuer (the "Excess Voting Securities") on each matter in the same proportion as the stockholders of the Issuer (other than the Covered Entities) vote their voting securities on such matters (disregarding stockholders that do not vote). The Voting Agreement will terminate automatically upon the earliest to occur of (i) the Covered Entities collectively ceasing to beneficially own 17.5% or more of the voting securities of the Issuer then outstanding, (ii) the Board of Directors of the Issuer (the "Issuer Board") having failed to nominate two (2) directors designated by IAC (should IAC elect to designate two (2) directors) who each meet the qualifications of a director set forth in the Issuer's Corporate Governance Guidelines (a "Qualified Director") to stand for election to the Issuer Board at the applicable annual meeting of shareholders (such nomination condition, the "Nomination Condition") and (iii) the occurrence of a change of control of the Issuer. If IAC determines not to designate one or more individuals to be nominated for election to the Issuer Board, the Voting Agreement will not terminate. In addition, in order to satisfy the Nomination Condition, if at any time fewer than two (2) directors on the Issuer Board have been designated by IAC, the Issuer Board is required to cause Qualified Director(s) to be added within one (1) month of designation by IAC, subject to the receipt of required regulatory approvals. As of the date of entry into the Voting Agreement, Mr. Diller was deemed to be designated to serve on the Issuer Board by IAC. In addition, Mr. Diller and his controlled affiliates, other than IAC and its controlled affiliates (collectively, the "Diller Entities"), will no longer be subject to the voting restriction with respect to any Excess Voting Securities, and the Diller Entities will no longer be considered Covered Entities, when both of the following conditions are satisfied: (i) Mr. Diller no longer serves as either the Chairman of the Board of Directors of IAC or as Senior Executive of IAC; and (ii) the Diller Entities no longer beneficially own voting securities of IAC representing at least one-third of the total voting power of the outstanding voting securities of IAC. The above summary is not complete and is qualified in its entirety by reference to the full text of the Voting Agreement, which is attached hereto as Exhibit 1 and incorporated herein by reference.
