Sidus Space Appoints Patent Attorney Mark R. Malek to Board of Directors

Third Board Appointment Since October Adds Deep Expertise in Technology Protection, International IP and AI Oversight

CAPE CANAVERAL, Fla., Nov. 12, 2026 /PRNewswire/ -- Sidus Space, Inc. (NASDAQ: SIDU) ("Sidus" or the "Company"), a vertically integrated space and defense technology systems integrator, today announced the appointment of Mark R. Malek to its Board of Directors, effective November 11, 2026. Mr. Malek, a registered patent attorney and co-founder of Widerman Malek, PL, will serve on the Board's Nominating/Corporate Governance Committee. He is the third director appointed since October, following Larry G. Swets Jr., CFA, and Hassan R. Baqar.

"Every appointment we have made since October has been tied to the growth of Sidus and its mission to support global and domestic space and defense priorities," said Carol Craig, Founder, Chief Executive Officer and Chairman of Sidus Space. "Larry and Hassan bring the financial reporting and capital markets discipline investors expect of a growing public company. Mark brings deep expertise in technology protection and AI, two areas where Board oversight matters more every year. Together, they give us a Board built for the Company's next stage of growth."

Mr. Malek's experience aligns directly with the Company's priorities:

• Intellectual property. Has obtained more than 1,000 U.S. and international patents for clients in aerospace, defense, drone and counter-drone, communications, and software, the same domains in which Sidus designs and builds satellites, mission computing hardware, and AI-enabled systems.
  
  
• Artificial intelligence. Advises companies that develop AI-enabled technologies and counsels organizations on integrating AI into their operations, with an emphasis on responsible use, data security, and protection of confidential information, supporting Board oversight as Sidus integrates AI across its space and defense offerings.
  
  
• International protection. Former Chair of the American Intellectual Property Law Association (AIPLA) Patent Cooperation Treaty Issues Committee and member of the U.S. Delegation for the International Association for the Protection of Intellectual Property (AIPPI); has directed international filing programs across many jurisdictions, supporting the Company as it expands its international customer base and partnerships.

Mr. Malek currently serves as an Equity Partner at Widerman Malek, PL, which he co-founded in 2003 and led as Managing Partner through 2021, growing the firm from four people to more than 75 attorneys and staff. He previously practiced as a patent agent and patent attorney at Allen, Dyer, Doppelt, Milbrath & Gilchrist, P.A. from 1999 to 2003.

"A technology company is only as strong as its ability to protect what it builds, and that work grows more complex as it extends into AI and international markets," said Mr. Malek. "Having followed Sidus closely for many years, I have a clear view of the strength of its technology and its team. I joined this Board because I believe in the Company's direction, and I look forward to contributing from my first meeting."

Mr. Malek holds a J.D. from Barry University School of Law, an MBA from the University of Orlando, and a B.S. in Civil Engineering from the University of Dayton and is registered to practice before the United States Patent and Trademark Office.
