Tom Lee’s BitMine Sells 9.5% Preferreds to Expand Ethereum Treasury, With Floating Liquidation Cushion

BitMine is doubling down on Ethereum while the market is still nursing losses. The company priced an upsized Series A Perpetual Preferred Stock offering to finance more ETH accumulation and staking infrastructure—importantly layering in a floating liquidation preference that attempts to protect preferred holders if things go sideways.

Key terms - Size and pricing: 3.5 million shares at $80 each (up from 3.0 million planned), raising an estimated $273.8 million before customary costs. - Dividend: 9.50% annual rate. - Listing: Applied to list on the NYSE under BMNP. - Timing and banks: Closing targeted for June 10; Moelis & Company and Cantor as joint lead bookrunners. - Liquidation preference: Floats upward based on recent market prices, with a hard floor at $100 per share. - Uses: Acquire additional Ethereum and other digital assets, fund MAVAN validator network for staking, and potentially repurchase common shares. - Current equity context: BitMine trades as BMNR.

What BitMine is really optimizing for The floating liquidation preference is the fulcrum. Preferreds in crypto-adjacent capital structures usually fix the liquidation stack and let the dividend carry the risk premium. Here, BitMine is trying to do two things at once: lock in a predictable 9.5% coupon to attract income-focused capital, while giving those holders a claim that steps up with market conditions rather than staying glued to par. In a volatile asset class, that structure implicitly acknowledges drawdown risk without conceding control of upside.

Why that matters now - Balance sheet vs. beta: BitMine pivoted from Bitcoin mining to an Ethereum treasury model last summer, now holding over $8.6 billion in ETH. With Ethereum falling from near $5,000 last August to about $1,591—down more than 67%—the firm’s position sits over $10 billion underwater per DropsTab data. The stock reflects that pressure, recently at $16, off about 10.5% on the day and down 41% year-to-date in 2026. - Fixed obligations in a cyclical market: A 9.5% coupon does not flex with ETH price. If digital asset markets weaken for longer, fixed distributions can tighten liquidity exactly when operating cash flows (staking rewards) and equity market access are least reliable. - Staking economics and cost of capital: Funding more validators through the MAVAN network should compound staking yield and improve ETH-denominated cash generation, but the math has to clear a 9.5% cash coupon after fees and friction. If ETH appreciates, the carry looks smart; if it ranges or drops, the preferred becomes a high-cost anchor.

The Strategy comparison is instructive BitMine is following a playbook that has worked for another treasury-heavy crypto company. Strategy’s preferred (STRC) helped bankroll billions of dollars in Bitcoin purchases this year. Strategy now holds over $51 billion in BTC, even as it shows a roughly $12 billion paper loss and its stock fell 36% in the past month to $118. The lesson isn’t that preferreds immunize equity; it’s that they can extend the runway to express a high-conviction asset thesis—provided the capital structure remains trusted.

Who this attracts—and who it doesn’t - Income investors seeking yield with a cushion may find the floating liquidation feature more intuitive than typical perpetual prefs in crypto. It signals an attempt at alignment. - Equity investors betting on treasury convexity may worry about subordination and cash leakage via the coupon just as the firm wants dry powder to buy weakness or repurchase common at discounts. - For institutions evaluating ETH exposure without holding tokens directly, BMNP can look like a hybrid: fixed income with equity-adjacent optionality tied to a large Ethereum balance sheet and staking operations.

Risks that still bite - Market-path dependency: If ETH remains range-bound, carry trades funded at 9.5% can under-earn. - Governance choices: Using proceeds for buybacks versus incremental ETH or staking capacity will shape downside protection—and may create tension between preferred and common holders. - Correlation shock: Crypto drawdowns often come with tighter financing conditions, raising the cost of rolling or expanding preferred layers.

BitMine is choosing to professionalize its capital stack while leaning further into its Ethereum treasury identity. The structure is thoughtful for this cycle; execution will come down to timing ETH accumulation, scaling MAVAN efficiently, and managing fixed obligations without starving growth—especially if volatility lingers.
