**Item 8.01. Other Information**

On June 5, 2026 (the "Closing Date"), Cartesian Growth Corporation III, a Cayman Islands exempted company ("CGC"), consummated the previously announced business combination pursuant to the terms of the business combination agreement, dated December 17, 2025, by and among CGC, Fenway MS, Inc., a Delaware corporation and wholly-owned subsidiary of CGC ("Merger Sub"), and Factorial Inc., a Delaware corporation ("Factorial") (as amended by Amendment No. 1 to Business Combination Agreement, dated as of March 26, 2026, and Amendment No. 2 to Business Combination Agreement, dated as of May 18, 2026, the "Business Combination Agreement"). Pursuant to the terms of the Business Combination Agreement, among other things, the following occurred: (1) the domestication of CGC as a Delaware corporation, in which CGC de-registered from the Register of Companies in the Cayman Islands and transferred by way of continuation out of the Cayman Islands and into the State of Delaware so as to migrate to and domesticate as a Delaware corporation in accordance with CGC's amended and restated memorandum and articles of association, Section 388 of the Delaware General Corporation Law (the "DGCL") and Part XII of the Cayman Islands Companies Act (As Revised) (the "Domestication"); (2) the merger of Merger Sub with and into Factorial with Factorial surviving the merger as a wholly-owned subsidiary of CGC (the "Merger"), in accordance with the Business Combination Agreement and the DGCL; and (3) the consummation of the other transactions contemplated by the Business Combination Agreement and documents related thereto (such transactions, together with the Domestication and the Merger, the "Business Combination"). In connection with the consummation of the Business Combination, CGC changed its corporate name to Factorial Energy Inc. ("PubCo").

This Current Report on Form 8-K (this "Current Report") references certain sections in CGC's definitive proxy statement/prospectus dated as of, and filed with the Securities and Exchange Commission pursuant to Rule 424(b) on, May 6, 2026 (the "Proxy Statement/Prospectus"). Terms used but not defined in this Current Report, or for which definitions are not otherwise incorporated by reference herein, shall have the meaning given to such terms in the Proxy Statement/Prospectus, and such definitions are incorporated herein by reference.

In connection with the Domestication, immediately prior to the Domestication, (1) CGC effected the redemption of 23,051,313 Class A ordinary shares of CGC, par value $0.0001 per share (the "CGC Class A Shares"), initially issued in CGC's initial public offering (the "Public Shares") that were validly submitted for redemption and not withdrawn; and (2) each holder, including CGC III Sponsor LLC, a Cayman Islands limited liability company and the sponsor of CGC, of each issued and outstanding Class B ordinary share of CGC, par value $0.0001 per share (the "CGC Class B Shares", and together with the CGC Class A Shares, the "CGC Ordinary Shares") irrevocably and unconditionally elected to convert, on a one-for-one basis, each CGC Class B Share held by it into one CGC Class A Share (the "Class B Share Conversion"). At the effective time of the Domestication, each outstanding CGC Class A Share (excluding Public Shares validly submitted for redemption, but including CGC Class A Shares issued upon the Class B Share Conversion) was reclassified as one share of Series A common stock, par value $0.00001 per share, of PubCo (the "PubCo Series A Common Stock").

The PubCo Series A Common Stock and PubCo Public Warrants have been approved for listing on the Nasdaq Capital Market under the new trading symbols "FAC" and "FACWW," respectively. Trading of the PubCo Series A Common Stock and PubCo Public Warrants under the new trading symbols will commence at the opening of trading on Monday, June 8, 2026.

Additional information will be set forth in a separate Current Report on Form 8-K to be filed within four business days after the Closing Date.
