<div id="readability-page-1"><article>NEW YORK and TEL AVIV, Israel, Dec. 17, 2025 (GLOBE NEWSWIRE) -- Nukkleus Inc. (NASDAQ: NUKK) (“Nukkleus” or the “Company”), a strategic acquirer and developer of high-potential businesses in the aerospace and defense (A&amp;D) industry, today announced that its stockholders have approved the acquisition of Star 26 Capital Inc., a defense-focused acquisition company. The transaction is expected to close before December 31, 2025. Pursuant to the approved transaction, Nukkleus is expected to acquire 100% of Star 26 in consideration of a mixed package of cash, equity, and promissory notes, subject to customary adjustments, as well as shares of Nukkleus common stock and associated warrants issued to Star 26 shareholders. Additional details regarding the transaction are available in the Company’s filings with the Securities and Exchange Commission. The transaction, which was first announced on December 15, 2024, was approved by Nukkleus stockholders at the Special Meeting of Stockholders held on December 16, 2025, is intended to provide Nukkleus with 100% ownership of Star 26 and its portfolio of defense-related assets. The period between signing and closing enabled Star 26 to expand and strengthen its holdings, increasing the strategic value of the transaction for Nukkleus and its shareholders and further accelerating the firm’s evolution into a unified, multi-domain defense technology company. Upon closing, the acquisition is expected to significantly enhance Nukkleus’s position across the military UAV and UAS value chain, which is expected to reach approximately $23 billion by 2030. It will enable deeper integration between unmanned platforms, artificial intelligence (“AI”), motion control, power systems, and command-and-control infrastructure. Upon closing, Nukkleus’s existing subsidiaries in AI, UAV systems, and GNSS-related technologies will now operate alongside Star 26’s companies, supporting the development of end-to-end unmanned and autonomous defense solutions spanning airborne platforms, payloads, ground control, and real-time decision-support systems. Star 26 brings to Nukkleus a portfolio of defense and technology companies that are complementary to unmanned and autonomous systems, including B. Rimon Agencies Ltd., a leading Israeli supplier of critical components for advanced missile-defense such as the Iron Dome, with exclusive distribution relationships with major defense contractors including Rafael Advanced Defense Systems and Elbit Systems. Star 26 also holds a majority interest in Water.io (TASE: WATR), which recently completed its acquisition of Zorronet, a developer of AI-powered unmanned command centers and integrated physical-security platforms, as well as a convertible loan position in ITS/Positech, a specialist in advanced motion-control, stabilization, and targeting technologies. These companies are expected to collaborate with Nukkleus’s existing portfolio across AI, UAVs, aerospace systems, command and control, and defense infrastructure, supporting integrated solutions that combine autonomous platforms with motion, sensing, and centralized control. Following the closing, the acquisition is expected to provide operational efficiencies through shared resources, streamlined supply chains, expanded distribution, and cross-platform integration, while each subsidiary continues to operate independently within its core domain. This approach supports Nukkleus’s ability to address evolving requirements in UAV, UAS, and related defense systems. “We are very pleased to have received stockholder approval for this acquisition,” said Menny Shalom, CEO of Nukkleus Inc. “This transaction is the next logical step for Nukkleus, as unmanned and autonomous systems become an integral part of modern defense, performance increasingly depends on how well hardware, control systems, and software work together. Bringing Star 26 and its portfolio under the Nukkleus umbrella enables closer collaboration across AI, UAVs, aerospace systems, and command and control, supporting integrated solutions that combine autonomy with motion and sensing. For shareholders, this structure is expected to improve operational efficiency through shared resources and coordinated supply chains, while positioning Nukkleus to address evolving requirements in UAS and related defense programs in a disciplined way.” At the special meeting, stockholders of the Company’s Common Stock also approved the issuance of shares upon conversion of the Company’s outstanding Series A Convertible Preferred Stock and associated warrants previously issued to investors, as well as the issuance of shares in connection with the Company’s $250 million equity line.
