Amendment: SEC Form SCHEDULE 13D/A filed by Penske Automotive Group Inc.

Item 3 of the Schedule 13D is hereby amended and supplemented as follows: To finance the transaction contemplated by the Proposal (as defined below), the Investor Group expects to enter into one or more debt commitment letters with third parties, with the remainder being funded by equity financing from the Investor Group. Any third-party financing for the transactions contemplated by the Proposal remains subject to negotiation of definitive agreements on terms acceptable to the Investor Group.

Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following after the final paragraph thereof: On July 22, 2026, the Investor Group submitted a non-binding proposal (the "Proposal") to the Board of Directors of the Company (the "Board") to acquire all of the outstanding Voting Common Stock, other than Voting Common Stock owned by the Investor Group, for $210.00 per share of Voting Common Stock in cash. The Reporting Persons anticipate that the Board will appoint a special committee consisting solely of disinterested and independent directors (a "Special Committee"), engage its own advisors, consider the Proposal with the assistance of such advisors, engage in discussions and negotiations with the Investor Group and potentially make a recommendation to the Board regarding the Proposal. Any agreement regarding the Proposal would require the approval of a Special Committee. The Investor Group stated in the Proposal that the members of the Investor Group, in their capacity as stockholders of the Company, are not interested in selling their shares of Voting Common Stock, including in connection with an alternative sale, merger or similar transaction involving the Company, and intend to remain as long-term stockholders of the Company, regardless of the outcome of the Proposal. If a transaction contemplated by the Proposal is ultimately consummated, the Voting Common Stock would be delisted from the New York Stock Exchange and deregistered under the Act. The foregoing description of the Proposal is qualified in its entirety by the full text of the Proposal, which is attached hereto as Exhibit 32 and incorporated herein by reference. While the Proposal is subject to negotiation with a Special Committee, should it be formed and engage with the Investor Group, the Reporting Persons and their affiliates and representatives may, directly or indirectly, take such additional steps as they may deem appropriate to further the Proposal or otherwise to support their investment in the Company, including, without limitation, responding to inquiries from the Company, the Board or a Special Committee (or its independent legal and financial advisors) or their representatives and engaging in discussions and negotiations regarding the Proposal with such persons. The Reporting Persons do not intend to update or provide additional disclosures regarding the Proposal or the transactions contemplated thereby until a definitive agreement has been entered into, or unless disclosure is otherwise required under applicable U.S. securities laws. The Investor Group also expects to engage in discussions and negotiations with potential financing sources and enter into one or more definitive debt commitment letters with third parties. The Proposal does not create any legal obligations, and no such obligations will arise unless and until definitive transaction documentation with the Company has been executed and delivered. No assurances can be given (a) that the Proposal will be accepted by a Special Committee, (b) that any definitive agreement will be entered into with respect to the transaction contemplated by the Proposal or any other potential transaction involving any member of the Investor Group and the Company, (c) if any such transaction is undertaken, as to its ultimate terms or timing, or (d) that any such transaction will be consummated. The Proposal is non-binding and the Investor Group reserves the right to modify or withdraw the Proposal at any time. The Proposal may result in one or more of the transactions, events or actions specified in clauses (a) through (j) of Item 4 of Schedule 13D, including, without limitation, an acquisition of additional securities (including Voting Common Stock) of the Company, an extraordinary corporate transaction (such as a merger) involving the Company, a delisting of the Voting Common Stock from the New York Stock Exchange and other material changes in the Company's business or corporate structure. The Reporting Persons will continue to regularly review and assess their investment in the Company and, depending on market conditions and other factors, reserve the right to, at any time, engage in, and to formulate other plans or make other proposals (and engage advisers to assess the merits of such other plans or other proposals) and to modify or withdraw any such plan or proposal at any time, which could result in one or more of the transactions, events or actions specified in clauses (a) through (j) of Item 4 of Schedule 13D.
