What Mill City Venture III does
Mill City Ventures III, Ltd. (now operating as SUI Group Holdings, NASDAQ: SUIG, formerly OTCQX: MCVT) is a publicly traded specialty finance company that historically operated as a non-bank lender originating short-term, high-yield loans and revolving credit facilities (e.g., a $5M revolving facility in January 2022 and a $2.5M credit facility yield increase plus $400K high-yield loan origination in July 2025). The company is headquartered in Wayzata, Minnesota, employs 1-10 people, and was founded in 2006. Leadership comprises CEO Douglas M. Polinsky, Chairman Marius Barnett, CFO Joseph A. Geraci II, CIO Stephen Mackintosh, and directors Dana Wagner and Howard Liszt, with additional digital-asset-focused board appointments planned.
In July 2025 the company executed a strategic pivot, closing a $450 million private placement selling 83 million shares to institutional investors led by London-based digital-assets hedge fund Karatage Opportunities and the Sui Foundation, with participation from Galaxy Digital, Pantera Capital, Arrington Capital, Big Brain Holdings, Borderless Capital, Electric Capital, FalconX, GSR, Maven 11, ParaFi and others. Approximately 98% of proceeds (~$441M) were allocated to acquiring SUI tokens as the company's primary treasury reserve asset, with the remaining ~2% supporting the continuing specialty finance business. By August 2025 the company held 81,871,794 SUI tokens (as of August 10, 2025), growing to approximately 102 million SUI tokens (~$403M) by September 2025, and authorized a $50 million stock repurchase program.
The company's underlying technology is built around the Sui blockchain, leveraging Sui's Move programming language (static typing, memory isolation), object-based parallel execution architecture, and sub-second (~400ms) transaction finality for any on-chain treasury or future lending activity. The company positions itself as the first publicly traded entity dedicated to a Sui treasury strategy, aiming to maximize SUI per share through treasury management and native protocol participation. Revenue mechanics are split between legacy specialty finance interest/yield income on a small lending book and indirect returns on the SUI treasury (token appreciation, staking, protocol economics), with options trading commencing on Cboe (August 22, 2025) and Nasdaq uplisting under the SUIG ticker (August 26, 2025) broadening institutional and retail distribution.
