Bitmine Immersion Technologies, Inc., BMNR

The company priced 3.5 million shares of 9.50% Series A Perpetual Preferred Stock at $80 per share. That’s up from the 3 million shares originally announced. Net proceeds are expected to come in at around $273.8 million, with the deal set to close on June 10, 2026.

The preferred stock carries a 9.50% cumulative annual dividend based on a $100 stated value per share. BitMine has applied to list it on the NYSE under the ticker BMNP, with trading expected to begin within 30 days of issuance.

The primary use of proceeds is straightforward: buy more ETH, fund staking infrastructure, and expand validator operations through MAVAN, the company’s proprietary staking initiative.

The structure draws clear comparisons to Strategy’s preferred stock playbook for Bitcoin. But BitMine’s pitch is that ETH has one thing BTC doesn’t — staking yield.

The Staking Yield Argument

The logic is that a company holding large ETH reserves can fund dividend obligations through staking returns rather than selling the underlying asset. Strategy, by contrast, sold 32 BTC earlier this year to cover dividend payments on its STRC preferred stock, which carries an 11.5% annual dividend. That sale pushed Bitcoin briefly below $62,000.

ETH staking currently yields around 3% to 5% annualized. That gap against a 9.50% preferred dividend is real, and it’s not ignored in BitMine’s own filing — the company lists additional ETH acquisition as a primary use of proceeds precisely because the math doesn’t close on staking yield alone.

BitMine Chairman Thomas Lee made the case at the Proof of Talk conference in France, arguing that ETH treasury firms can use staking yields to fund ecosystem grants and governance participation — turning yield into both a financial return and a strategic tool.

Standard Chartered’s head of digital assets research, Geoffrey Kendrick, has backed a version of this thesis, suggesting staking-funded operations give ETH treasury firms a structural edge over their Bitcoin equivalents over time.

The Risks Are Real

The staking-yield argument depends on Ethereum staking returns staying stable enough to cover obligations. They fluctuate with network participation, MEV conditions, and protocol changes. That’s not a fixed income stream.

BitMine has publicly targeted holding roughly 5% of Ethereum’s total circulating supply. Analysts have flagged that concentration as a risk — a corporate holder at that scale becomes a meaningful variable in ETH price dynamics.

The company also carries legacy mining infrastructure and costs that a pure treasury firm wouldn’t have. Transitioning from a mining operation to a staking treasury is a full business model shift, not a simple accounting reclassification.

BMNR was trading down 5.4% premarket at the time of writing, with the offering set to close June 10.
