Sidus Space Issues Letter to Shareholders Highlighting Progress and Next Phase of Growth

The letter outlines the Company's progress and priorities across commercialization, capital allocation and balance-sheet strength, technology development, and government and defense market alignment.

"Today, our focus is shifting from proving our technology to scaling its commercial application and that distinction is important," said Carol Craig, Founder, Chief Executive Officer and Chairman of Sidus Space. "Success is no longer measured simply by launching satellites or demonstrating technical capability. It will increasingly be measured by customer adoption, recurring revenue, operating leverage, and long-term shareholder value."

The Next Chapter of Sidus Space

Key Highlights from the Letter to the Shareholders include:

• Approximately $170 million raised over the past six months to strengthen the balance sheet, accelerate commercialization, and provide long-term financial flexibility.
• Inclusion in the Russell 2000, Russell 3000, and Russell Microcap Indexes, expanding institutional visibility.
• Successful design, manufacture, launch, and on-orbit demonstration of multiple generations of the LizzieSat platform, validating our vertically integrated capabilities.
• Advancement of the Fortis VPX digital mission computing platform and Orlaith AI ecosystem through testing in preparation for customer evaluations and commercialization.
• Continued progression through production and integration of two next-generation, software-defined LizzieSat spacecraft, designed to support rapidly evolving mission requirements on orbit.
• Expanded pipeline across defense, intelligence, civil, and commercial markets, including the Missile Defense Agency SHIELD contract vehicle.
• Expanded international presence and strategic partnerships to broaden global market access and diversify revenue opportunities.
• Modernization of 35,000-square-foot vertically integrated manufacturing, assembly, integration, test, and mission operations footprint to incorporate emerging technologies, enabling the scalable production of next-generation, orbit-agnostic space and defense solutions.
