On July 9, 2025, RMG Acquisition Corp. III. (the "Company") issued a press release announcing that because the Company will not consummate an initial business combination within the time period required by its Fifth Amended and Restated Memorandum and Articles of Association, the Company intends to redeem all of the outstanding shares of Class A ordinary shares that were included in the units sold in its initial public offering (the "Public Shares"), at a per-share redemption price of approximately $10.00 and thereafter dissolve and liquidate.

As of the close of business on July 9, 2025, the Public Shares will be deemed cancelled and will represent only the right to receive the redemption amount. Record holders will receive their pro rata portion of the proceeds of the trust account, subject to the Company's obligations under Cayman Islands law to provide for claims of creditors, by delivering their Public Shares to Continental Stock Transfer & Trust Company, the Company's transfer agent. Beneficial owners of Public Shares held in "street name," however, will not need to take any action in order to receive the redemption amount. The redemption of the Public Shares is expected to be completed within ten business days after July 9, 2025.

RMG Sponsor III, LLC (the "Sponsor") has agreed to waive its redemption rights with respect to (i) its outstanding Class B ordinary shares issued prior to the Company's initial public offering and (ii) its 3,500,000 outstanding Class A ordinary shares that were converted from Class B ordinary shares into Class A ordinary shares on December 26, 2023. There will be no redemption rights or liquidating distributions with respect to the Company's warrants, which will expire worthless.

Nasdaq filed a Form 25 with the United States Securities and Exchange Commission (the "Commission") to delist the Company's securities on June 28, 2024. The Company hereafter expects to file a Form 15 with the Commission to terminate the registration of its securities under the Securities Exchange Act of 1934, as amended.

The board of directors of the Company has recommended and approved that, in connection with the redemption and delisting of the Company's Public Shares and distribution of its trust account, the Company appoint Alvarez & Marsal Cayman Islands Limited as voluntary liquidators of the Company. The voluntary liquidators' role will include determining the next steps for liquidating and/or distributing the Company's remaining assets following the redemption of the Public Shares. The proposed voluntary liquidators are wholly independent of the Company's existing management, its board of directors and its Sponsor.

A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

The information in this Current Report on Form 8-K, including Exhibit 99.1, is being furnished pursuant to Item 7.01 and shall not be deemed "filed" for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise be subject to the liabilities of that section, nor shall it be deemed to be incorporated by reference into any of the filings of the Company under the Securities Act of 1933, as amended, or the Exchange Act, whether made before or after the date hereof, regardless of any general incorporation language in any such filing.
