Rhea-AI Filing Summary

Hadron Energy, Inc., formerly SPAC GigCapital7, completed its business combination with Hadron Energy Operating Company, becoming a Nasdaq-traded light-water micro‑modular reactor company under the symbols HDRN and HDRNW.

Before the shareholder meeting, holders of 16,834,491 Public Shares out of 20,000,000 redeemed at $10.71267171 per share, for an aggregate $180,342,375.50, leaving 3,165,509 Public Shares and about $33.9 million in the trust account immediately prior to closing. After redemptions and unit separation, there were 71,498,842 shares of common stock outstanding, public warrants for 20,000,000 shares at $11.50, private warrants for 3,719,000 shares at $11.50, and additional 5,000,000 warrants at $12.00.

Press materials state that approximately $28 million of trust cash plus about $2.8 million from $7.5 million of SAFE bridge financings produced roughly $31 million of cash at closing, and about $24.45 million after roughly $6.5 million of expenses, with no debt. Directors, executives and affiliates beneficially owned about 75.9% of the combined company, while former GigCapital7 shareholders held about 23%. Concurrently, Hadron entered into an amended Registration Rights Agreement covering resale registrations and a Lock-Up Agreement restricting certain insiders from selling their shares for defined periods or until trading and transaction-based triggers are met.

Insights

SPAC and capital-structure analyst

De-SPAC closes with high redemptions but modest equity capital and no debt.

Hadron Energy completed its merger with GigCapital7, converting the SPAC into a public light‑water micro‑modular reactor developer. Redemptions were substantial: 16,834,491 of 20,000,000 Public Shares were redeemed at $10.71267171, leaving relatively few public shares.

Despite this, the company reports about $31 million of cash at closing, including trust funds and SAFE bridge financing, and expects roughly $24.45 million after approximately $6.5 million in expenses, with zero debt. An amended Registration Rights Agreement and a Lock-Up Agreement structure future resale mechanics and insider liquidity timing.

As of the business combination, insiders and affiliated entities hold about 75.9% of outstanding common stock, with former GigCapital7 shareholders at about 23%. This concentrated ownership and limited initial float may influence trading dynamics while the company pursues its Halo MMR development and NRC engagement in periods such as the first year post-closing.

Key Terms

Business Combination Agreement, Registration Rights Agreement, Lock-Up Agreement, SAFE bridge financings, +2 more

6 terms

Business Combination Agreement financial

"pursuant to that certain Business Combination Agreement, dated as of September 27, 2025"

A business combination agreement is a detailed contract that lays out the terms for two companies to join together—covering price, how ownership will be split, the steps needed to close the deal, and what each side promises to do or avoid before closing. For investors it matters because the agreement determines potential changes in value, control, timing, and risk exposure—think of it like the playbook for a merger that shows who wins, who pays, and what could still derail the plan.

Registration Rights Agreement financial

"entered into an Amended and Restated Registration Rights Agreement (the “Registration Rights Agreement”)"

A registration rights agreement is a contract that gives investors the option to have their ownership stakes officially registered with the government, making it easier to sell their shares later. This agreement matters because it provides investors with a clearer path to cash out their investments if they choose, offering more liquidity and confidence in their ability to sell their holdings when desired.

Lock-Up Agreement financial

"entered into a Lock-Up Agreement (the “Lock-Up Agreement”)"

A lock-up agreement is a contract that prevents company insiders and early investors from selling their shares for a fixed period after a stock sale, often after an initial public offering. It matters to investors because it temporarily limits the number of shares that can hit the market, which can keep the share price steadier; when the lock-up ends, a sudden increase in available shares can create extra volatility, revealing insiders’ confidence or lack thereof.

SAFE bridge financings financial

"secured $7.5 million of equity-cash through SAFE bridge financings conducted prior to the closing"

Short-term financing that uses SAFEs (Simple Agreements for Future Equity) as the vehicle: investors give cash now in exchange for a promise that the money will convert into shares at the next priced funding round instead of being repaid as a loan. It matters to investors because these deals change how much of a company will be owned by whom after conversion — like an IOU that becomes stock — so the conversion terms, discounts and valuation caps directly affect future ownership stakes and returns.

micro-modular nuclear reactor technical

"developing the Halo Micro-Modular Nuclear Reactor (MMR) which is a 10 megawatt electric"

A micro-modular nuclear reactor is a small, factory-built power unit that produces a modest amount of electricity or heat and is designed to be mass-produced and combined with other units as needed. Like building blocks for power, these compact reactors aim to reduce on-site construction time and allow flexible deployment for utilities, industry, or remote sites; that potential affects project size, capital needs, and market opportunities that investors track.

emerging growth company regulatory

"Emerging growth company"

An emerging growth company is a recently public or smaller public firm that qualifies for temporary, lighter regulatory and disclosure rules to reduce the cost and effort of being public. For investors, it means the company may provide less historical financial detail and face fewer reporting requirements than larger firms, so it can grow more quickly but also carries higher uncertainty—like buying a promising early-stage product with fewer user reviews.

Introductory Note

On May 22, 2026, Hadron Energy, Inc. (f/k/a GigCapital7 Corp. (“GigCapital7”)) (the “Company” or “Combined Company” or “Hadron Energy”) consummated (the “Closing”) its business combination (the “Business Combination”) with Hadron Energy Operating Company Inc. (f/k/a Hadron Energy, Inc.) (“Hadron Energy Operating Company”) 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, and all exhibits and schedules thereto, by and among the Company, MMR Merger Sub, Inc. and Hadron Energy Operating Company (the “Business Combination Agreement”). In connection with the consummation of the Business Combination, the Company changed its name from GigCapital7 Corp. to Hadron Energy, Inc. 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 Securities and Exchange Commission (the “SEC”) on April 15, 2026 by the Company.

Prior to the extraordinary general meeting of shareholders of the Company held on May 7, 2026 (the “Extraordinary Meeting”), the holders of 16,834,491 shares of GigCapital7’s common stock out of 20,000,000 shares of common stock (or about 84% of the Public Shares) that were sold in its initial public offering (“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 shares of 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 issued and outstanding shares of Combined Company 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 5,000,000 shares of Combined Company Common Stock issued to former warrant holders of Hadron Energy Operating Company issued 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 date of Closing, the directors and executive officers and their affiliated entities beneficially owned approximately 75.9% of the outstanding shares of shares of Combined Company Common Stock, and the former shareholders of GigCapital7 beneficially owned approximately 23% of the outstanding shares of Combined Company Common Stock.

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.

Exhibit 99.2

Hadron Energy Completes Business Combination with GigCapital7

Corp. Receiving Approximately $31 Million; Begins Trading on Nasdaq

Under Ticker “HDRN” as the First Publicly Traded Light-Water Micro-

Modular Nuclear Reactor Company

Closing follows GigCapital7 Corp. shareholder vote on May 7, 2026; Hadron and GigCapital7

together secured approximately $31 million in total funding all in equity and with zero debt

NEW YORK, NY — May 26, 2026 — Hadron Energy, Inc. (Nasdaq: HDRN) (“Hadron Energy” or the “Company”), is developing the Halo Micro-Modular Nuclear Reactor (MMR) which is a 10 megawatt electric (MWe), central factory manufactured, transportable, light-water reactor designed to deliver continuous, carbon-free baseload power, and with a 10 year refueling cycle. Today, Hadron announced the successful closing of its previously announced business combination with GigCapital7 Corp. (previously Nasdaq: GIG) (“GigCapital7”), the seventh private-to-public equity (PPE)^™ enterprise, also known as SPAC, incepted by the GigCapital Global franchise since 2017. At closing, $28 million of cash remained and was not redeemed from the GigCapital7 trust account and was transferred to the Company’s balance sheet, far exceeding the $20 million minimum cash at closing as was agreed and defined on the Q3’2025 business combination agreement (BCA), with zero debt at closing. In addition, since signing the BCA, Hadron and GigCapital7 secured $7.5 million of equity-cash through SAFE bridge financings conducted prior to the closing, of which about $2.8 million remained on the balance sheet at the closing, for a total combined amount of cash of approximately $31 million, and due to the very low transaction and related expenses, as a result of the unique GigCapital Global closing methodology, the Company will have about $24.5 million in cash on the balance sheet following all transaction expenses. Following the approval of GigCapital7’s shareholders at the extraordinary general meeting (EGM) held on May 7, 2026, the Company’s common stock and warrants will commence trading on the Nasdaq Stock Market under the ticker symbols “HDRN” and “HDRNW”, respectively, on May 26, 2026, making Hadron Energy the first publicly traded light-water micro-modular nuclear reactor (MMR) company.

Hadron Energy — Closing Press Release — May 12, 2026 — 1

This successful transaction closing provides Hadron Energy with the required capital to operate the Company according to its business plan for the next year, public-market access, and the strategic flexibility to advance the Halo MMR through design, regulatory, and customer-deployment milestones at a pace and scale that the Company believes it will lead the next chapter of America’s nuclear renaissance in an efficient manner.

“Today marks the start of a new chapter for Hadron Energy. Now being a well-capitalized public company with no debt, we are executing with conviction on our development plan and NRC licensing pathway. The Halo MMR will be built on light-water reactor technology, the most thoroughly commercialized technology in the nuclear industry, and engineered to be central factory-built, easily transportable by commercial vehicles, and rapidly deployable with no need to refuel over 10 years. We identified the 10 megawatt electric (MWe) nuclear reactor to be the optimal footprint for the growing customer-based markets. We are positioned to scale the partnerships, supplier capacity, and talent base needed to deliver firm, on-site power to major industrial sites, data centers, defense installations, and mission-critical civilian facilities. This effort has been prioritized by the U.S. Administration as showcased by Hadron’s letter of support from the White House signed by the President last fall. We believe Hadron will optimize national and energy security with our Halo Microreactor,” said Sam Gibson, Founder and Chief Executive Officer of the Company.

“We are extremely proud to have completed this business combination with Hadron Energy. From our earliest engagement with Sam Gibson and his team, we recognized in Hadron Energy the combination of their participation in an attractive and relevant deep-tech environmental-friendly industry that has been highly prioritized by the current U.S. leadership as well as many other global administrations, their deployment of well-proven and lengthy sustained safe technology by using the light-water reactor technology, their disciplined execution, and a clear-eyed commercial strategy they have planned, all are the elements that GigCapital always looks for in our partners. The successful closing, with Hadron Energy emerging from it with approximately $31 million in equity capital, no debt on its balance sheet, and the lowest demonstrated deSPAC closing costs, reflects the GigCapital Global deployed methodology and commitment to delivering a company-friendly, clean and durable capital structure that maximizes Hadron Energy’s operational flexibility as it scales as a public company. We believe Hadron Energy is positioned to be the leading companies in defining America’s nuclear energy renaissance, and we look forward to our active partnership in supporting Hadron Energy as a ‘Mentor-Investor’ ^TM in its next chapter as a Nasdaq-traded public company,” said Dr. Avi Katz, Founder, Chairman and Chief Executive Officer of GigCapital7 Corp. and Executive Chairman of Hadron Energy, Inc.

Transaction Financing

Since signing the Business Combination Agreement, Hadron Energy and GigCapital7 worked together directly to secure the capital needed to bring Hadron Energy to the public markets. In closing, about $21.5 million were retained in the trust in Non-Redemption Agreements with small number of GigCapital7 shareholders, ensuring that trust proceeds remained intact to fund the newly launched public company, and factoring in all additional shares that were not redeemed, a total of about $28 million in cash was released to the Company’s balance sheet from the GigCapital7 trust account. In addition, Hadron and GigCapital7 secured $7.5 million through SAFE bridge financings conducted between signing the BCA in Q3’2025 and prior to the closing, of which about $2.8 million remained on the balance sheet at the closing, for a total combined amount of cash of approximately $31 million prior to the payment of approximately $6.5 million of transaction and related expenses and some small amount of deferred payment. Following such payments, the Company will have approximately $24.45 million in cash and zero debt on its balance sheet. Notably, all capital was raised directly by Hadron Energy and the GigCapital7 joint-team, without reliance on external investment banking capital raises.
