Note 21     SUBSEQUENT EVENT

Reverse Stock Split

On June 25, 2026, the Company's Board of Directors approved the Reverse Stock Split, pursuant to stockholder authorization obtained at the Company's annual meeting held on January 12, 2026. The Reverse Stock Split became effective on July 6, 2026, at which time every 30 shares of common stock issued and outstanding were automatically combined into one share, without any change in par value. Immediately prior to the Reverse Stock Split, the Company had 46,806,289 shares of common stock issued and outstanding, which were reduced to 1,560,210 shares. No fractional shares were issued; holders otherwise entitled to a fractional share received a cash payment in lieu thereof. Proportionate adjustments were made to the exercise prices and number of shares issuable under all outstanding stock options, warrants, and restricted stock units, as well as shares reserved under the Company's equity incentive plans. The Reverse Stock Split was undertaken to enable the Company to satisfy the minimum bid price requirement for continued listing on The Nasdaq Capital Market.

In accordance with ASC 260, Earnings Per Share, all share and per-share amounts presented in these unaudited condensed consolidated financial statements and accompanying notes for all periods presented have been retroactively adjusted to reflect the Reverse Stock Split.

Letter of Intent with INERGX Energy Optimisation Ltd.

On July 6, 2026, the Company entered into a non-binding letter of intent (the "LOI") with INERGX Energy Optimisation Ltd ("INERGX"), a company incorporated in England and Wales, regarding the Company's proposed acquisition of up to 9.99% of the issued and outstanding equity interests of INERGX (the "Proposed Transaction"). The Proposed Transaction may be structured as a stock purchase, share exchange, contribution, recapitalization, or other mutually agreed structure, with consideration consisting of a combination of cash and shares of the Company's common stock in proportions to be determined in definitive documentation. Valuation assumptions under the LOI remain preliminary and subject to the Company's due diligence review, and no purchase price or other economic term will be final unless and until set forth in a definitive agreement. Consummation of the Proposed Transaction remains subject to, among other things, completion of due diligence, negotiation and execution of a definitive acquisition agreement, and receipt of any required board, regulatory, third-party, and stockholder approvals. The LOI does not obligate either party to consummate the Proposed Transaction and terminates upon the earliest of execution of a definitive agreement, mutual written agreement, 30 days' prior written notice by either party, or the 90th day following the date of the LOI. There can be no assurance that the parties will enter into a definitive agreement or that the Proposed Transaction will be consummated on the terms described herein or at all. Because the LOI does not obligate the parties to consummate the transaction and its economic terms remain preliminary, the Company has not recognized any financial statement impact related to the LOI as of the date these financial statements were available to be issued.
