(the “Company”) entered into a Secured Revolving Line of Credit Agreement (the “Line of Credit Agreement”) and Secured Revolving Line of Credit Agreement Note (“Line of Credit Note”) between the Company and MBB Energy, LLC, a New York limited liability company, pursuant to which the Company may request one or more loans of up to an aggregate principle amount $1,000,000 under this line of credit for a period of one (1) year (the “Term”) from the date or entry. Any loans drawn by the Company under this line of credit facility will carry interest on an annualized basis of 8%, payable monthly on the first day of each month thereafter. MBB Energy, LLC is an affiliate and related party of the Company by virtue of MBB Energy, LLC being an entity controlled by Messrs. Scott Maskin and James Brennan. During the Term, the Company may from time to time borrow, repay and reborrow all or part of the outstanding balance of the loans drawn thereunder on or after the date hereof and prior to the initial Maturity Date of April 15, 2026, subject to the terms, provisions and limitations set forth in the Agreement.   On April 14, 2026, the Board of Directors of the Company agreed to amend the Line of Credit Agreement and the Line of Credit Note in two principal respects: (i) to extend the Maturity Date by six (6) months to October 15, 2026 (“New Maturity Date”), and (ii) to increase the aggregate dollar capacity of the Line of Credit Agreement by fifty percent from a previous total of $1,000,000 to a new aggregate total of $1,500,000 (“Line of Credit Capacity”). Accordingly, the Company has amended the Line of Credit Agreement and amended the Line of Credit Note, in each case to reflect the New Maturity Date and increased Line of Credit Capacity.   Long Term Note   As previously disclosed, in connection with the acquisition of the New York based subsidiaries of SUNation on November 9, 2022, the Company issued a $5,486,000 Long-Term Promissory Note (the “Long-Term Note”). On April 10, 2025, the Long-Term Note was amended and restated whereby the principal amount of $5,486,000 previously due and payable under the original Long-Term Note, together with all accrued and unpaid interest owing thereunder, became due and payable on May 1, 2028, and such amended note became a senior secured instrument of the Company. Principal and interest payments under the amended Long-Term Note are payable monthly on the first day of each month commencing on June 1, 2025 for thirty-six (36) consecutive months thereafter.   On April 14, 2026, the Board of Directors approved entry into a “Debt Conversion Agreement” in connection with the conversion of up to $1,200,000 of debt payable under the Long-Term Note into shares of restricted common stock (the “Conversion Shares”) of the Company pursuant to Regulation D of the Securities Act of 1933, as amended, on the following terms: (1) the Conversion Shares shall consist of restricted shares of voting common stock, par value $.05 per share, (2) the Conversion Shares shall be issued at a price per share of $1.77, which reflects a premium of 10% above the closing price of the Company’s common stock on Nasdaq Stock Market on April 13, 2026 (and also above the 5-day closing average), and (3) the Conversion Shares shall be locked-up (non-tradeable, non-transferable and non-saleable) for a period of 180 days from the date of issuance, and further subject to such other applicable SEC and Nasdaq Stock Market rules, regulations and restrictions, including Rule 144, on shares held by persons deemed to be control persons or affiliates of the Company.   The conversion of debt to equity of the Long-Term Note will reduce the outstanding secured debt of the Company payable under the Long-Term Note in the near term by approximately $1,200,000. The Conversion Shares shall be issued to Messrs. Scott Maskin and James Brennan, each of whom is an affiliate and related party of the Company by virtue of their respective roles as chief executive officer and chief financial officer of the Company.   The foregoing description of the amended Line of Credit Agreement, Line of Credit Note and Debt Conversion Agreement, in each case, does not purport to be complete and are qualified in their entirety by reference to the full text of the amendment to the Line of Credit Agreement, amended Line of Credit Note, and the Debt Conversion Agreement, each of which are filed herewith as Exhibits 10.1, 10.2 and 10.3, respectively, to this Current Report on Form 8-K and are incorporated herein by reference.   1   Item 2.03 Creation of a Direct Financial Obligation or an Obligation under Off-Balance Sheet Arrangement of a Registrant.   The information set forth in Item 1.01 is incorporated herein by reference.   Item 3.02 Unregistered Sales of Equity Securities.   The information set forth in Item 1.01 is incorporated herein by reference.   Item 7.01 Regulation FD Disclosure   On April 15, 2026, the Company issued a press release announcing the reduction of debt under the Long-Term Note, as well as the conversion of the foregoing debt to equity at a premium to the per share market price.
