Deployment of capital begins immediately with industry-first relationship providing institutional-grade access to blockchain built for mass adoption

Karatage co-founders Marius Barnett and Stephen Mackintosh become Chairman of the Board and Chief Investment Officer, respectively

WAYZATA, Minn.--(BUSINESS WIRE)--Jul. 31, 2025-- Mill City Ventures III, Ltd. ("Mill City" or the "Company") (NASDAQ: MCVT) today announced the successful closing of its $450,000,000 private investment in public equity and has commenced implementation of its industry-first Sui blockchain treasury strategy.

Karatage Opportunities (“Karatage”), the London-based proprietary hedge fund specializing in digital assets and emerging technology investments, founded by Marius Barnett and Stephen Mackintosh, acted as the lead investor, with an equivalent investment from the Sui Foundation, an independent organization dedicated to the advancement and adoption of the Sui network. Barnett has now been appointed as Chairman of the Board, and Mackintosh now serves as its Chief Investment Officer.

Investors included prominent firms and infrastructure providers Big Brain Holdings, Galaxy Digital Inc (Nasdaq: GLXY) and Dr Jack Kong – NLABS Fund. Other notable investors included Pantera Capital, ATW Partners, M2, Electric Capital, GSR, Selini, Protagonist, ParaFi Capital, Borderless, dao5, Arrington Capital, Comma3 Ventures, FalconX, Paper Ventures, Maven 11, and LVNA Capital, among others. Galaxy Asset Management will serve as the Asset Manager.

A.G.P./Alliance Global Partners acted as the sole placement agent in connection with the offering.

Mill City now has a total of 76,271,187 SUI in its treasury, acquired at an average price of $3.6389 per token after having made its first purchases through an OTC purchase and sale agreement with the Sui Foundation and contributions in kind. Retail and institutional traders now have access to the Company’s treasury via a publicly-traded wrapper with daily liquidity. Mill City intends to continue its SUI accumulation strategy by purchasing additional tokens on the open market. By working with the Sui Foundation, Mill City is the only crypto treasury strategy with official foundation backing on the market today.

Sui is one of the only blockchains built for mass adoption, designed to provide scalability, speed, and security to support the next generation of decentralized applications and real-world crypto use-cases for consumers and institutions alike — from stablecoins to artificial intelligence to gaming to finance. Mill City's treasury strategy positions investors to benefit from this technological advantage at a pivotal moment when institutional crypto adoption is currently accelerating.

"Not all crypto treasury strategies are created equal, and we believe that Mill City Ventures is building something truly different with Sui," said Stephen Mackintosh, newly appointed Chief Investment Officer of Mill City. “Our differentiated treasury strategy supporting this innovative blockchain is made possible through access to institutional-grade deal flow and an aligned vision with the Sui Foundation. Our Sui strategy is about more than passively holding tokens; it’s about actively partnering with the ecosystem to maximize long-term value creation."

“Mill City is breaking new ground by offering public market investors a clean, liquid, and institutional-grade way to access the broader digital asset ecosystem. Anchoring its treasury to SUI, and pairing that with seasoned leadership, creates a powerful structure for long-term growth and exposure to one of the most promising blockchain platforms out there,” added Mike Novogratz, Founder and CEO of Galaxy. “Galaxy is proud to support this innovative model as it opens the door for traditional capital to participate in crypto’s next chapter.”

Led by visionary former Meta technologists who Mark Zuckerberg charged with developing the company's Diem stablecoin project, Sui has attracted serious developers building breakthrough applications across finance, gaming, and AI, while major financial institutions have begun creating regulated investment products around the network.

"We see Mill City’s treasury strategy — and the wave of institutional backing that it has ushered in — as major validation that Sui's object-centric architecture and Move programming language represent the future of blockchain infrastructure," said Adeniyi Abiodun, Co-Founder and Chief Product Officer of Mysten Labs, the original contributors to Sui.

Mill City will continue providing short-term lending and structured finance solutions. It will additionally dedicate approximately 98% of the private placement net proceeds to SUI acquisition and treasury management. Mill City expects to provide regular updates on its SUI holdings and treasury performance as it looks to build the largest institutionally-managed SUI position in the public markets.
