(“GigCapital7”)) (the “Company” or “Combined Company” or “Hadron Energy”) consummated its business combination (the “Business Combination”) with Hadron Energy Operating Company Inc. (f/k/a Hadron Energy, Inc.) (“Hadron Energy Operating Company”) on May 22, 2026, pursuant to that certain Business Combination Agreement, dated as of September 27, 2025, as amended by that certain First Amendment to Business Combination Agreement, dated as of December 12, 2025, and by that certain Second Amendment to Business Combination Agreement, dated as of April 16, 2026 (the “Second Amendment”), by and among GigCapital7, MMR Merger Sub, Inc. and Hadron Energy Operating Company (the “Business Combination Agreement”). Certain terms used in this Current Report on Form 8-K have the same meaning as set forth in the final proxy statement/prospectus (the “Final Proxy Statement/Prospectus”) filed with the SEC on April 15, 2026 by GigCapital7, as supplemented by the Supplement.

As previously reported in the Current Report on Form 8-K filed with the SEC on May 8, 2026, on May 7, 2026, GigCapital7 held an extraordinary general meeting of shareholders (the “Extraordinary Meeting”). At the Extraordinary Meeting, the GigCapital7 shareholders considered and adopted, among other matters, the Business Combination Agreement. As previously reported in the May 28 Current Report, on May 22, 2026, the parties to the Business Combination Agreement consummated the Business Combination (such consummation, the “Closing” and the date thereof, the “Closing Date”).

As also previously reported in the May 28 Current Report, prior to the Extraordinary Meeting, the holders of 16,834,491 shares of GigCapital7’s common stock that were sold in its initial public offering (“Public Shares”), out of 20,000,000 shares of common stock (or about 84% of the Public Shares), exercised their right to redeem those shares for cash at a price of $10.71267171 per share, for an aggregate of $180,342,375.50, which redemption occurred concurrent with the Closing, and the balance of 3,165,509 shares (or about 16% of the Public Shares) reflected cash that remained in the trust account upon the Closing. Immediately after giving effect to the Business Combination (including as a result of the redemptions described above and the automatic separation of GigCapital7 units into Hadron Energy common stock (“Combined Company Common Stock”) and warrants for the purchase of shares of Combined Company Common Stock), there were (i) 71,498,842 shares of Hadron Energy’s issued and outstanding common stock, (ii) public warrants for the purchase of 20,000,000 shares of Combined Company Common Stock with an exercise price of $11.50 per share, (iii) private warrants for the purchase of 3,719,000 shares of Combined Company Common Stock with an exercise price of $11.50 per share, and (iv) warrants for the purchase of 5,000,000 shares of Combined Company Common Stock issued to former warrant holders of Hadron Energy Operating Company pursuant to the terms of the Business Combination Agreement, with an exercise price of $12.00 per share. Upon the Closing, GigCapital7’s units ceased trading, and Hadron Energy’s common stock began trading on The Nasdaq Stock Market LLC (the “Nasdaq”) under the symbol “HDRN” and the public warrants began trading on Nasdaq under the symbol “HDRNW.” As of the Closing Date, the directors and executive officers and their affiliated entities beneficially owned approximately 77.2% of Hadron Energy’s outstanding shares of common stock, and the former shareholders of GigCapital7 beneficially owned approximately 23% of Hadron Energy’s outstanding shares.

As noted above, the per share redemption price of $10.71267171 for holders of Public Shares electing redemption was paid out of GigCapital7’s trust account, which after taking into account the redemptions, had a balance immediately prior to the Closing of approximately $33.9 million.
