Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following paragraphs at the end of Item 4: On December 19, 2024, Goodwood Inc. ("Goodwood") sent a letter (the "December 19 Letter") to the Board of Directors of the Issuer. The December 19 Letter outlines Goodwood's concerns about, among other things, the excessive amount of wasted research and development and other expenses that the Issuer's board continues to permit. The December 19 Letter also outlines Goodwood's view that the Issuer's current strategy is not sustainable, nor is it in the best interests of the Issuer's shareholders. The December 19 Letter states that the Issuer needs substantial change to its board composition to regain the confidence of its shareholders, and that the reconstituted board must, among other things, immediately prioritize value creation and shareholders' interests and move rapidly to cut costs and eliminate unnecessary spending on long-shot R&D programs. The December 19 Letter also states that Goodwood stands ready to engage with the Issuer's board on the changes that must be made to both the board and the Issuer's strategy, and that absent those changes being promptly implemented, Goodwood intends to propose new directors for election to the Issuer's board. The Reporting Persons may also propose or take one or more of the other actions described in subsections (a) through (j) of Item 4 of Schedule 13D and may discuss such actions with the Issuer and the Issuer's management and board, other shareholders of the Issuer and other interested parties. The foregoing description of the December 19 Letter does not purport to be complete and is qualified in its entirety by reference to the full text of such letter, which is filed as Exhibit 99.2, and is incorporated herein by reference. The Reporting Persons acquired the Shares to which this Schedule 13D/A relates for investment purposes in the ordinary course of business. The Reporting Persons purchased the Shares because they believed that such Shares, when purchased, represented an attractive investment opportunity. The Reporting Persons have engaged, and intend to continue to engage, in communications with one or more officers, directors and/or representatives or agents of the Issuer and/or other persons, and may in the future also engage in communications with one or more shareholders of the Issuer and other relevant parties, regarding actions that might be taken with respect to the foregoing. As part of such communications, the Reporting Persons may advocate one or more courses of action. Depending on various factors including, without limitation, the Issuer's financial position and strategic direction, the outcome of the discussions referenced above, actions taken by the board of directors of the Issuer, the market value of the Common Stock, other investment opportunities available to Reporting Persons, conditions in the securities market and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate, including, without limitation, purchasing additional shares of Common Stock or selling some or all of their shares of Common Stock, transferring shares of Common Stock, engaging in short selling of, or any hedging or similar transactions with respect to, the shares of Common Stock and/or otherwise changing their intention with respect to any and all matters referred to in Item 4 of Schedule 13D. There can be no assurance that the Reporting Persons will pursue any of the matters set forth above. Moreover, there can be no assurance that the Reporting Persons will or will not develop any alternative plans or proposals with respect to any of the foregoing matters or take any particular action or actions with respect to some or all of their holdings in the Issuer, or as to the timing of any such matters should they be so pursued by the Reporting Persons. The Reporting Persons reserve the right, at any time and in each Reporting Person's sole discretion, to take or refrain from taking any of the actions set forth above. Except as described in this Item 4, as of the date of this statement the Reporting Persons have no present plan or proposal that relates to or would result in any of the matters set forth in subsections (a) through (j) of Item 4 of Schedule 13D.
