Mill City Ventures III Bets Big on SUI

Mill City Ventures III ((SUIG)) has held its Q4 earnings call. Read on for the main highlights of the call.

Mill City Ventures III’s latest earnings call painted a picture of strong strategic momentum undercut by harsh accounting optics. Management highlighted rising on-chain activity, growing ecosystem partnerships, and robust treasury yields, yet GAAP results were dominated by a huge noncash mark-to-market hit on SUI tokens that turned operational progress into a headline net loss and spotlighted concentration risk.

Governance Upgrade with High-Profile Board Appointment

Mill City strengthened its board by adding Brian Quintenz, a former CFTC Commissioner and ex-a16z crypto policy head, as an independent director. The move is designed to bolster governance, deepen regulatory expertise, and better position the company as it navigates complex rules around digital assets and institutional on-chain strategies.

Bluefin Partnership Drives Yield and Ecosystem Liquidity

The company spotlighted its partnership with Bluefin, the leading decentralized exchange on SUI, which has scaled to over $4 billion in monthly trading volume and roughly $80–$82 billion cumulatively. Mill City’s institutional lend to Bluefin is currently generating an attractive 17–18% annual yield paid weekly in SUI, reinforcing its thesis of monetizing the SUI ecosystem.

Stablecoin Infrastructure and the suiUSDe Vault Anchor

Mill City, alongside Ethena and the SUI Foundation, launched suiUSDe and USDi to deepen stablecoin infrastructure on SUI. It deployed $10 million into an Ember-operated suiUSDe vault that is now earning around a 10% yield, anchoring liquidity formation and showcasing how the treasury is being actively deployed into yield-bearing DeFi opportunities.

Treasury Staking Strategy Builds SUI-Denominated Rewards

Management has substantially staked its SUI holdings, generating roughly 1.7% annualized yield in SUI rewards. Since launching the treasury strategy in July 2025, staking and lending activities have produced about 1.13 million SUI, evidencing gradual but tangible growth in token-denominated income streams.

Share Repurchases Signal Confidence and Capital Discipline

The board authorized a $50 million share buyback program, and in Q4 the company repurchased approximately 7.8 million shares at an average price of $2.02. Those Q4 purchases alone represented about 8.8% of shares outstanding at the time, and management later indicated around 80 million shares repurchased over time, underscoring a shareholder-return focus.

Revenue Surge and Stronger Cash Position

Gross revenue and portfolio income jumped 179% year over year in Q4 to $2.4 million from $869,000, reflecting the early payoff from treasury activation. Cash and cash equivalents climbed to $21.9 million as of Dec. 31, 2025, up from $6.0 million a year earlier, a roughly 265% increase that provides meaningful liquidity for continued deployment.

SUI Holdings Cement Institutional Gateway Role

Mill City held 105,086,451 SUI valued at $147.4 million plus a digital asset loan receivable of 2,961,550 SUI worth $3.6 million, making it a sizable institutional gateway to the SUI ecosystem. Management touted SUI’s technical edge, including its object-centric architecture, Move language, and PTBs, as well as product upgrades like DeepBook margin trading that could deepen network usage.

Noncash Mark-to-Market Hit Distorts GAAP Results

Q4 results were heavily affected by a $196.1 million noncash unrealized and realized loss on SUI and related digital asset loans driven by mark-to-market accounting. Management stressed that this accounting treatment, rather than operational underperformance, was the primary reason GAAP numbers swung so sharply despite rising revenues and on-chain activity.

GAAP Net Loss and Expense Line Swell on Token Volatility

The quarter closed with a GAAP net loss of $221.8 million, or $5.52 per diluted share, versus a negligible $91,000 loss a year earlier. Operating expenses ballooned to about $203 million in Q4 2025 from roughly $960,000, but excluding digital asset fair-value adjustments and stock-based compensation, underlying operating expenses were closer to $4.8 million.

Concentration and Scale Risks Temper Bullish Narrative

Management acknowledged that holding over 105 million SUI creates high balance-sheet concentration and fair-value volatility, as the latest mark-to-market swing made clear. They also noted that even with 179% growth, $2.4 million of quarterly revenue remains small relative to the size and volatility of their token portfolio and the risks of DeFi lending and protocol exposure.

Guidance Centers on SUI Per Share and Yield Targets

Looking ahead, Mill City plans to prioritize growing SUI per share by activating its treasury through staking, lending, derivatives, and stablecoin infrastructure while remaining opportunistic with buybacks under the $50 million program. The company is targeting a longer-term objective of approaching roughly a 10% yield on SUI over 12–18 months, supported by current yields near 1.7% from staking, approximately 10% from the Ember vault, and mid-teens returns from institutional lends like Bluefin.

Mill City Ventures III’s earnings call offered a mix of strategic confidence and balance-sheet reality for investors tracking SUI-linked plays. The company is clearly leaning into its role as an institutional bridge to the SUI ecosystem, but the quarter also underscored how token volatility and concentration can overwhelm fundamentals, making execution, diversification, and risk control critical watchpoints ahead.
