Appointment Further Strengthens Regulatory and Policy Leadership as Company Advances SUI Treasury Strategy

SUI Group Holdings Limited (NASDAQ:SUIG) ("SUI Group," "SUIG" or the "Company") today announced the appointment of Brian Quintenz as an independent director to the Company's board of directors (the "Board"), effective January 5, 2026. Mr. Quintenz will also serve on the audit committee of the Board. Mr. Quintenz's appointment follows the transition of the Company's Chief Financial Officer, Joseph A. Geraci, II, from Director, a position from which he has now resigned, to Board Observer. With the appointment of Mr. Quintenz, SUI Group's Board now comprises five members, three of whom the Board has determined to be independent under applicable Nasdaq rules.

Mr. Quintenz is a widely recognized leader in financial markets, public policy, and digital asset regulation. He currently serves on the board of Kalshi, an event-based derivatives exchange regulated by the U.S. Commodity Futures Trading Commission (the "CFTC") and has advised a range of leading institutions across the digital asset and financial services ecosystems.

Previously, Mr. Quintenz served as Global Head of Policy for a16z crypto, where he led policy strategy and engagement for one of the world's most influential digital asset investment platforms. He also served as a Commissioner of the CFTC, having been nominated by Presidents Obama and Trump, and unanimously confirmed by the U.S. Senate. During his tenure, he played a central role in shaping regulatory frameworks for derivatives, fintech, and digital assets, including early oversight of Bitcoin futures markets.

"Brian is a widely respected leader in the digital asset industry, with a rare combination of capital markets expertise, regulatory credibility, and deep infrastructure knowledge," said Marius Barnett, Chairman of the Board. "His decision to join our Board and support our SUI treasury strategy represents a meaningful validation of both SUIG and the long-term potential of the Sui ecosystem. As we scale our efforts, we expect Brian's experience to be critical to maintaining institutional rigor, engaging constructively with policymakers, and positioning SUIG as a long-term participant in the institutional adoption of SUI."

Prior to his public service, Mr. Quintenz was the Founder and Managing Principal of Saeculum Capital Management and held a senior investment and advisory role at Hill-Townsend Capital, and served as a senior policy advisor in the U.S. House of Representatives.
