Item 7.01 Regulation FD Disclosure.

On September 15, 2025, SUNation Energy, Inc. (the “Company”) posted its updated investor presentation (“Investor Presentation”) to its Company website. A copy of the updated Investor Presentation is furnished as Exhibit 99.1 to this Current Report on Form 8-K.

The Investor Presentation includes financial information not prepared in accordance with generally accepted accounting principles (“Non-GAAP Financial Measures”). The Company believes that the Non-GAAP Financial Measures set forth in the Investor Presentation provide a more complete understanding of our current business than could be obtained absent such inclusion. We believe the Non-GAAP Financial Measures also provide investors a useful tool to assess shareholder value, among other customary tools.

The information contained in this Item 7.01 and the Investor Presentation shall not be deemed “filed” for any purpose, including for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that Section. The information in this Item 7.01, as well as Exhibit 99.1shall not be deemed filed or incorporated by reference into any filing under the Securities Act of 1933, as amended, or the Exchange Act regardless of any general incorporation language in such filing.

The statements in this Current Report on Form 8-K, and in Exhibit 99.1 hereto, contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are based on current expectations and beliefs about future events or circumstances, and investors should not place undue reliance on these statements. Such statements involve known and unknown risks, uncertainties, assumptions and other factors, many of which are out of the Company’s control and difficult to forecast. These factors may cause actual results to differ materially from those that are anticipated. See the Company’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and other reports and material that it files with the Securities and Exchange Commission for a further description of these and other risks and uncertainties. The Company assumes no, and hereby disclaims any, obligation to update any forward-looking statements, but reserves the right to make such updates from time to time without the need for specific reference to this Form 8-K or the presentation furnished as Exhibit 99.1 hereto. No such update shall be deemed to indicate that other statements which are not addressed by such an update remain correct or create an obligation to provide any other updates
