Mill City Announces Corporate Rebrand to SUI Group Holdings to Advance SUI Treasury Strategy

New Ticker Symbol “SUIG” to Begin Trading on August 26, 2025

WAYZATA, Minn., Aug. 25, 2025 (GLOBE NEWSWIRE) — Mill City Ventures III, Ltd. (“Mill City” or the “Company”) (NASDAQ: MCVT), today announced plans to implement a comprehensive corporate rebrand to advance its foundation-backed SUI treasury strategy. As part of this rebrand, the Company will change its corporate name to SUI Group Holdings Limited (“SUI Group”). The Company will also change the ticker symbol for its common stock on the Nasdaq Capital Market, and the ticker symbol for its common stock available for options trading on the Cboe Global Markets, from “MCVT” to “SUIG”. The changes are expected to take effect as of market open on or about August 26, 2025.

The rebrand will reflect SUI Group’s new strategic direction following its recently announced SUI treasury strategy centered on the Sui blockchain. As the only publicly traded company with an official relationship with the Sui Foundation, SUI Group provides institutional-grade exposure to the SUI digital asset and aligns with the Sui Foundation’s three principles for decentralization: transparency to ensure fairness, open communication to build trust and direct engagement to foster active community participation.

“This strategic rebrand marks a defining moment in SUI Group’s evolution as we align our identity with our mission to be the premier, foundation-backed SUI treasury company,” said Stephen Mackintosh, Chief Investment Officer of SUI Group. “Our disciplined strategy centers on the long-term accumulation and activation of SUI to support the advancement and adoption of the Sui network. Our rebrand and new ticker symbol reflect our commitment to unlocking differentiated, long-term value for shareholders by anchoring our treasury to the blockchain infrastructure of tomorrow.”

No action is required from stockholders in connection with the change of the Company’s corporate name or ticker symbol. The Company’s common stock will remain listed on the Nasdaq Capital Market and its common stock will continue to be available for options trading on Cboe Global Markets.
