Nukkleus Inc. Regains Full Nasdaq Compliance

Company’s recent private placement and $250million line of equity strengthen its balance sheet and supports growth strategy

New York, NY – September 29, 2025 – Nukkleus Inc. (Nasdaq: NUKK) (“Nukkleus” or the “Company”), a strategic acquirer and developer of high-growth businesses in the Aerospace and Defense (A&D) industry, today announced that it has regained full compliance with the Nasdaq Global Market’s minimum market capitalization requirement. The Company believes that this milestone, together with its recently announced $10 million PIPE and $250 million line of equity, positions the Company for continued growth.

The recently disclosed private placement significantly strengthens the Company’s balance sheet and market capitalization, reaffirming its ability to maintain Nasdaq standards. This compliance achievement, combined with Nukkleus’ addition to the Russell Microcap Index, is expected to enhance the Company’s visibility and credibility with the investment community.

The Company believes the resolution of the Nasdaq deficiency note will help address concerns previously expressed by institutional investors regarding compliance-related risks. Additionally, maintaining Nasdaq compliance and index inclusion is expected to attract enhanced analyst coverage, providing greater market transparency and research support for current and prospective investors.

The private placement is also expected to enable Nukkleus to accelerate its strategic acquisition program in the A&D sector and advance its European expansion plans, once the registration is declared effective. With greater financial flexibility, the Company is positioned to identify and scale high-potential businesses while continuing to deliver consistent, long-term value to shareholders. Nukkleus’ strengthened financial position underscores its operational resilience and strategic focus on building a diversified, innovation-driven A&D platform designed to generate sustainable growth and measurable returns.

“The successful resolution of our compliance matters, coupled with our Russell Microcap Index inclusion and the strong institutional interest we’re seeing, marks a pivotal moment for Nukkleus,” said Menny Shalom, Chief Executive Officer of Nukkleus Inc. “The planned $250 million equity line, which will only be available upon the effectiveness of the related registration statement, further supports our growth and acquisition strategy. Together, these developments strengthen investor confidence and positions us to execute on our acquisition pipeline while delivering exceptional value to our stakeholders.”
