Item 1.01. Entry into a Material Definitive Agreement.

Merger Agreement

On June 5, 2026, SUNation Energy, Inc., a Delaware corporation (“SUNation”), SUNation Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of SUNation (“Merger Sub”), and Suniva, Inc., a Delaware corporation (“Suniva”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which, among other matters, and subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, Merger Sub will merge with and into Suniva, with Suniva continuing as a wholly owned subsidiary of SUNation and the surviving corporation of the merger (the “Merger”). The Merger is intended to qualify for federal income tax purposes as a tax-free reorganization under the provisions of Section 368(a) of the Internal Revenue Code of 1986, as amended.

Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger (the “Effective Time”): (a) each then-outstanding share of Suniva capital stock (including shares of Suniva common stock and shares of Suniva preferred stock) will be converted into the right to receive a number of shares of SUNation common stock calculated in accordance with the Merger Agreement (the “Exchange Ratio”); (b) each then-outstanding Suniva warrant will be cancelled at the Effective Time, with each warrantholder entitled to receive for each warrant share a number of shares of SUNation common stock equal to the Exchange Ratio, taking into account the per share exercise price of the warrant; and (c) each then-outstanding Suniva restricted stock unit will be fully vested and converted into shares of SUNation common stock at the Exchange Ratio.

Under the Exchange Ratio in the Merger Agreement, upon the closing of the Merger, on a pro forma basis and based upon the number of shares of SUNation common stock expected to be issued in the Merger, pre-Merger Suniva stockholders are expected to own approximately 98.2% of the combined company and pre-Merger SUNation stockholders are expected to own approximately 1.8% of the combined company. The percentage of the combined company that each party’s stockholders will own following the closing is subject to adjustments as described in the Merger Agreement for the amount of SUNation’s net cash at closing relative to a specified target.

For purposes of calculating the Merger Consideration, (a) shares of SUNation common stock underlying SUNation stock options, warrants and other rights to receive shares outstanding as of immediately prior to the closing of the Merger will be deemed to be outstanding, (b) shares of SUNation common stock issuable upon the settlement of SUNation restricted stock units (excluding performance-based restricted stock units for which the performance condition has not been met) will be deemed to be outstanding, and (c) all shares of Suniva common stock underlying outstanding Suniva stock options, Suniva restricted stock units and Suniva warrants will be deemed to be outstanding.

In connection with the Merger, SUNation will seek the approval of its stockholders of, among other things, (a) the issuance of shares of SUNation common stock in connection with the Merger on the terms and conditions set forth in the Merger Agreement, (b) if Suniva deems it advisable, an amendment and restatement of SUNation’s amended certificate of incorporation, (c) if deemed necessary by SUNation and Suniva, an amendment to SUNation’s amended certificate of incorporation to effect a reverse stock split of all outstanding shares of SUNation’s common stock, (d) the conversion of certain secured insider debt to SUNation common stock, and (e) an increase in the number of shares of SUNation common stock reserved for issuance under the existing SUNation equity incentive plan of no less than 5% of the projected total post-Merger number of outstanding shares of SUNation common stock. To the extent necessary or deemed appropriate, additional proposals may be added by the SUNation board of directors, which will be included in any prospectus/proxy statement relating to the special meeting of stockholders.

Each of SUNation and Suniva has agreed to customary representations, warranties and covenants in the Merger Agreement, including, among others, covenants relating to (a) using commercially reasonable efforts to obtain the requisite approval of its stockholders, (b) non-solicitation of alternative acquisition proposals, (c) the conduct of their respective businesses during the period between the date of signing the Merger Agreement and the closing of the Merger, (d) SUNation using commercially reasonable efforts to maintain the existing listing of SUNation common stock on The Nasdaq Capital Market and cause the shares of SUNation common stock to be issued in connection with the Merger to be approved for listing on The Nasdaq Capital Market prior to the closing of the Merger and (e) SUNation filing with the U.S. Securities and Exchange Commission (the “SEC”) and causing to become effective a registration statement to register the shares of SUNation common stock to be issued in connection with the Merger (the “Registration Statement”).

Consummation of the Merger is subject to certain closing conditions, including, among other things, (a) approval by SUNation stockholders of the matters being put to their vote, (b) approval by the requisite Suniva stockholders of the adoption and approval of the Merger Agreement and the transactions contemplated thereby, (c) Nasdaq’s approval of the listing of the shares of SUNation common stock to be issued in connection with the Merger, (d) the effectiveness of the Registration Statement, and (e) SUNation’s net cash not being less than negative $1,500,000. Each party’s obligation to consummate the Merger is also subject to other specified customary conditions, including regarding the accuracy of the representations and warranties of the other party, subject to the applicable materiality standard, and the performance in all material respects by the other party of its obligations under the Merger Agreement required to be performed on or prior to the date of the closing of the Merger.

The Merger Agreement contains customary termination rights of each of SUNation and Suniva. Upon termination of the Merger Agreement under specified circumstances, SUNation may be required to pay Suniva a termination fee of $1,000,000, and Suniva may be required to pay SUNation a termination fee of $1,000,000. The Merger Agreement may be terminated if the Merger has not been consummated on or before January 30, 2027, subject to a potential sixty (60)-day extension in certain circumstances as set forth in the Merger Agreement.

At the Effective Time, the Board of Directors of SUNation is expected to consist of five members, all of whom will be designated by Suniva.

Voting Agreements

Concurrently with the execution of the Merger Agreement, certain key stockholders of SUNation (solely in their respective capacities as SUNation stockholders) holding approximately 10.4% of the outstanding shares of SUNation capital stock have entered into voting agreements with SUNation and Suniva to vote all of their shares of SUNation capital stock in favor of the adoption and approval of the Merger Agreement and the transactions contemplated thereby (the “Voting Agreements”).

The preceding summaries of the Merger Agreement and the Voting Agreement do not purport to be complete and are qualified in their entirety by reference to the Merger Agreement and the form of Voting Agreement, which are filed as Exhibits 2.1 and 10.1, respectively, to this Current Report on Form 8-K and which are incorporated herein by reference. The Merger Agreement has been attached as an exhibit to this Current Report on Form 8-K to provide investors and securityholders with information regarding its terms. It is not intended to provide any other factual information about SUNation or Suniva or to modify or supplement any factual disclosures about SUNation in its public reports filed with the SEC. The Merger Agreement includes representations, warranties and covenants of SUNation, Suniva and Merger Sub made solely for the purpose of the Merger Agreement and solely for the benefit of the parties thereto in connection with the negotiated terms of the Merger Agreement. Investors should not rely on the representations, warranties and covenants in the Merger Agreement or any descriptions thereof as characterizations of the actual state of facts or conditions of SUNation, Suniva or any of their respective affiliates. Moreover, certain of those representations and warranties may not be accurate or complete as of any specified date, may be subject to a contractual standard of materiality different from those generally applicable to SEC filings or may have been used for purposes of allocating risk among the parties to the Merger Agreement, rather than establishing matters of fact.

The press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K and incorporated herein by reference, except that the information contained on the websites referenced in the press release is not incorporated herein by reference.

The information in this Item 7.01, including Exhibit 99.1 attached hereto, shall not be deemed “filed” for 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, nor shall it be deemed incorporated by reference in any filing under the Securities Act or the Exchange Act, except as expressly set forth by specific reference in such filing.

Forward-looking statements are based on current beliefs and assumptions that are subject to risks and uncertainties and are not guarantees of future performance.

Actual results could differ materially from those contained in any forward-looking statement as a result of various factors, including, without limitation: the risk that the proposed Merger may not be completed on the anticipated timeline or at all; the failure to obtain required stockholder approvals, SEC effectiveness of the Form S-4 registration statement, or Nasdaq listing approval; the parties’ ability to satisfy the conditions to closing and to close expected financing; risks relating to constructing, equipping, permitting and ramping up the Laurens facility on time and on budget; the ability to convert offtake agreements into realized revenue; competition, tariffs, trade actions and changes in tax incentives, including the Section 45X advanced manufacturing production credit; technology, supply-chain and execution risks; the accuracy of third-party market data and forecasts; the operating history of Suniva; potential net losses incurred as a result of the current expansion-stage nature of Suniva, as well as net losses carried forward from SUNation’s longstanding business operations; the ability to raise additional capital; the ability of Suniva to execute on its business plans and for the combined companies to integrate SUNation’s solar installation systems into Suniva’s solar cell manufacturing operations; the effects of the One Big Beautiful Act of 2025 on the residential solar industry, which has had a material negative impact on residential solar installations since the January 2026 effectiveness thereof; Suniva’s limited experience in operating a public company; the substantial competition Suniva faces in developing and selling its solar cell development products; the ability to attract, hire, and retain skilled executive officers and employees; the ability of SUNation or Suniva to protect their respective intellectual property and proprietary technologies; reliance on third parties, contract manufacturers, and contract research organizations; uncertainties as to the timing of the consummation of the proposed transactions and the ability of each of the parties to consummate the proposed transactions; risks related to SUNation’s continued listing on Nasdaq until the closing of the proposed transactions; risks related to SUNation’s and Suniva’s ability to correctly estimate their respective operating expenses and expenses associated with the proposed transactions, as well as uncertainties regarding the impact any delay in the closing would have on the anticipated cash resources of the combined company upon closing and other events and unanticipated spending and costs that could reduce the combined company’s cash resources; the occurrence of any event, change or other circumstance or condition that could give rise to the termination of the Merger Agreement; competitive responses to the proposed transactions; unexpected costs, charges or expenses resulting from the proposed transactions; the outcome of any legal proceedings that may be instituted against SUNation, Suniva or any of their respective directors or officers related to the Merger or the proposed transactions contemplated thereby; potential adverse reactions or changes to business relationships resulting from the announcement or completion of the proposed transactions; the effect of the announcement or pendency of the transactions on SUNation’s or Suniva’s business relationships, operating results and business generally; compliance with and qualification for initial listing on Nasdaq related to the expected trading of the combined company’s stock on Nasdaq and the combined company’s ability to remain listed following the proposed transactions; the risk that, as a result of adjustments to the Exchange Ratio as set forth in the Merger Agreement, SUNation’s stockholders and Suniva’s stockholders could own more or less of the combined company than is currently anticipated; risks related to the market price of SUNation common stock relative to the Exchange Ratio; legislative, regulatory, political and economic developments and general market conditions, including those surrounding the viability of residential solar businesses following the loss of federal tax credits beginning in January 2026; and the other risks described in SUNation’s most recent Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K filed with the SEC, the registration statement on Form S-4 to be filed with the SEC by SUNation, as well as risk factors associated with companies, such as Suniva, that operate in the energy and manufacturing industry.
