TORRANCE CA 90503 Item 2(a) is hereby amended to add the following: SiCPower no longer beneficially owns any securities of the Issuer and, accordingly, is no longer a member of a Section 13(d) group with Dr. Singh and shall cease to be a Reporting Person immediately after the filing of this Amendment No. 2 to the Schedule 13D. Dr. Singh will continue filing statements on Schedule 13D with respect to his beneficial ownership of securities of the Issuer to the extent required by applicable law. Item 3 is hereby amended and restated as follows: The 18,645,603 Shares directly owned by Dr. Singh were transferred in a private transaction on July 28, 2025 from SiCPower to Dr. Singh. The aggregate purchase price of the 18,645,603 Shares directly owned by Dr. Singh is approximately $163,894,850, excluding brokerage commissions. Item 4 is hereby amended to add the following: Dr. Singh has served as a member of the Board of Directors of the Issuer (the "Board") since November 2024 and previously entered into a Cooperation Agreement (as defined in Amendment No. 1 to the Scheduled 13D) with the Issuer, the substantive provisions of which generally expired on April 9, 2026. On April 23, 2026, Dr. Singh sent an email to the Chairman of the Board, Richard Hendrix, expressing his concerns with (i) the excessively long tenures of certain members of the Board, (ii) a general lack of alignment by such Board members who have sold most of their shares of the Issuer, (iii) the lack of relevant expertise and experience of certain members of the Board in the Issuer's core business, and (iv) the unnecessary and dilutive capital raises undertaken by the Board. Dr. Singh stated in the email that with the terms of three (3) long-tenured Class II directors expiring at the Issuer's upcoming annual meeting of stockholders, the Board should be thoughtfully refreshed by cycling off such directors who no longer have any meaningful skin in the game and adding new directors with relevant experience and fresh perspectives. Dr. Singh further stated that, to the extent the Board does not meaningfully engage with him to address these concerns, he intends to nominate at least two candidates for election at the Issuer's upcoming annual meeting of shareholders. Dr. Singh remains open to a constructive dialogue and hopes to find a mutually agreeable path forward with his fellow Board members.

Each of the Reporting Persons specifically disclaims beneficial ownership of the Shares reported herein that he or it does not directly own.
