Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On January 26, 2026, the Board of Directors (the “Board”) of ALT5 Sigma Corporation (the “Company”), upon the recommendation of the Company’s Nominating and Corporate Governance Committee, appointed Dr. Adel ElMessiry, Ph.D., to serve as an independent director of the Company, subject to his acceptance of the appointment. Dr. ElMessiry accepted the appointment on January 29, 2026.

In connection with his appointment, the Board reviewed Dr. ElMessiry’s qualifications and determined that he qualifies as an “independent director” under the Nasdaq Listing Rules.

Since August 2020, when he co-founded AlphaFin, a financial technology company focused on decentralized and blockchain-powered financial systems, Dr. ElMessiry has served as its President and Chief Technology Officer. From August 2020 to March 2021, he also served as AlphaFin’s Chief Executive Officer, during which time he helped establish the company’s strategic and technical foundations. Since January 2025, Dr. ElMessiry has served as Technical Co-Founder of Lussa, a technology venture based in Dubai. In addition, since January 2024, he has served as a board member of the Nashville Entrepreneur Center, a nonprofit organization supporting startup and entrepreneurial development.

Dr. ElMessiry is also the Founder of WebDBTech, a technology architecture and development firm he has led since 2000, providing advisory and development services across Web3, enterprise software, and data-driven systems. From June 2016 to October 2020, Dr. ElMessiry served as Chief Technology Officer of Utilize Health, where he led technology strategy, product development, cybersecurity initiatives, and HIPAA-compliant system architecture. His earlier executive experience includes serving as Associate Vice President at HealthTrust Purchasing Group from November 2014 to April 2016, following its acquisition of InVivoLink, where Dr. ElMessiry had served as Chief Technology Officer.

Dr. ElMessiry holds a Ph.D. in Computer Science and a Master’s degree in Computer Engineering from North Carolina State University. The Company believes that Dr. ElMessiry’s experience in technology leadership, fintech, blockchain systems, and governance, together with his service on nonprofit and advisory boards, provides him with the qualifications to serve as a director.

There are no related-party transactions involving Dr. ElMessiry that are reportable under Item 404(a) of Regulation S-K. Other than his appointment as a director, there are no material plans, contracts, or arrangements to which Dr. ElMessiry is a party or in which he participates, and there have been no material amendments to any such plans, contracts, or arrangements in connection with his appointment.
