INFORMATIONCONTAINED IN THIS REPORT ON FORM 6-K

On July 31, 2026 (ET), Carbon Revolution Public Limited Company (the “Company”) (CREV) announced that UMB Bank, National Association (the “Petitioner”), acting by its lawfully appointed attorney, OIC Structured Equity Fund I GPFA Range, LLC (“OIC”), filed a petition with the High Court of Ireland seeking orders for the winding up of, and the appointment of liquidators to, the Company pursuant to section 569(1)(d) of the Companies Act 2014 (as amended) of Ireland on the grounds that the Company is unable to pay its debts.

Subsequently, on July 31, 2026 (ET), and following an ex parte application made by the Petitioner (acting by its lawfully appointed attorney, OIC), the High Court of Ireland made orders for the appointment of Nicholas O’Dwyer and Colm Dolan, each of Grant Thornton Ireland, to act as joint liquidators of the Company on a provisional basis pending the hearing of the winding up petition, which is scheduled for October 19, 2026 (ET) in Dublin, Ireland.

As disclosed in the Company’s Report on 6-K dated May 18, 2026, the Company’s then-wholly owned Australian subsidiaries emerged from Voluntary Administration in Australia. Such Australian subsidiaries included Carbon Revolution Pty Ltd and Carbon Revolution Operations Pty Ltd (the “Australian Subsidiaries”).

As a result of the Voluntary Administration, the Company no longer holds any equity interest in the Australian Subsidiaries or their businesses and, accordingly, has only minimal assets or operations and no ability to pay its debts. Following the completion of the Voluntary Administration, OIC is the Company’s principal stockholder and the Petitioner is the Company’s principal creditor.

As also previously disclosed, 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. Such Restructuring Support Agreement also provides for funding from OIC for the liquidation in accordance with Irish law.
