Hennessy Capital VII Closes Business Combination; Renamed ONE Nuclear

What Happened

• Hennessy Capital Investment Corp. VII (HVII) filed an 8-K on September 23, 2026 announcing the closing of its previously announced business combination with ONE Nuclear Energy, LLC pursuant to agreements dated October 22, 2025 (with subsequent amendments). Upon closing, HVII was renamed ONE Nuclear Energy Inc. (New ONE Nuclear). The company’s common stock (par value $0.0001) is expected to begin trading on Nasdaq on September 24, 2026 under the ticker symbol "ONEN." CEO Richard Taylor presented at the Nuclear Innovation Summit on September 23; his presentation is furnished as Exhibit 99.2 to the filing.

Key Details

• Business combination closed: September 23, 2026; parties included HVII, Solis Merger Sub LLC and ONE Nuclear Energy, LLC.
• Nasdaq listing: New ONE Nuclear Common Stock expected to commence trading on Sept 24, 2026 under ticker "ONEN."
• Redemptions: Holders of 13,809,029 Class A ordinary shares redeemed at approximately $10.61 per share, for an aggregate redemption payment of about $146.5 million.
• Trust balance: After those redemptions and prepayments under a previously disclosed forward purchase agreement (and before paying expenses), approximately $2.2 million remained in HVII’s trust account following the closing.
• Exhibits filed: press release (Exhibit 99.1) and investor presentation used at the summit (Exhibit 99.2).

Why It Matters

• The filing confirms HVII has completed its merger and becomes a public operating company under the ONE Nuclear Energy name, with shares trading on Nasdaq — a key liquidity and visibility event for shareholders and potential investors.
• Large shareholder redemptions (≈$146.5M) substantially reduced the SPAC trust balance to roughly $2.2M, which affects the cash remaining from the initial IPO trust after closing (before expenses).
• The CEO’s investor presentation and the press release provide the company’s initial public disclosures about strategy and outlook as a listed company; investors should review those exhibits for additional information.
