INFORMATION CONTAINED IN THIS REPORT ON FORM 6-K

On May 18, 2026 (ET), Carbon Revolution Public Limited Company (the “Company”) (CREV) announced that the Company’s wholly owned Australian subsidiaries have emerged from Voluntary Administration in Australia. Such Australian subsidiaries include Carbon Revolution Pty Ltd and Carbon Revolution Operations Pty Ltd (the “Australian Subsidiaries”).

As disclosed in the Company’s 6-K dated March 26, 2026, the Company and its Australian Subsidiaries entered into a Restructuring Support Agreement with substantially all its senior secured lenders, who agreed to the financial recapitalization of Carbon Revolution’s business in Australia pursuant to the Voluntary Administration.

The organized recapitalization was recommended for approval by the Administrators who were appointed by the Board of the Australian Subsidiaries, and was approved by the Australian Subsidiaries’ creditors.

Following completion of the recapitalization of the Australian business through the Voluntary Administration, the Company has now ceased to have any continuing equity interest in the Australian Subsidiaries or their businesses. It is anticipated that a process will shortly commence for the orderly wind down and liquidation of Carbon Revolution plc, in accordance with Irish law.
