BitMine Files $300M 9.5% Preferred Stock Offering to Expand ETH Staking

BitMine Immersion Technologies is taking a bigger step into the public-market crypto treasury playbook — but with Ethereum at the center. The Norwalk, Connecticut company filed to sell a tranche of preferred stock that could fund more ETH purchases and beef up its validator and staking infrastructure. Why it matters - The move mirrors the capital-markets strategy popularized by Michael Saylor’s MicroStrategy — issuing yield-oriented securities in public markets to raise cash for digital-asset accumulation — but BitMine is applying that template to Ethereum rather than Bitcoin. - BitMine has already committed to ETH as its primary treasury reserve and uses protocol-level income (staking and DeFi) as part of its asset strategy. In 2026 it launched MAVAN (Made-in-America VAlidator Network) to house dedicated staking infrastructure for its assets. The offering at a glance - What was filed: 3,000,000 shares of 9.50% Series A Perpetual Preferred Stock, registered under the Securities Act. - Stated amount: $100 per share — implying up to $300 million of stated value if fully sold, though the company said the deal is subject to market and other conditions. - Intended uses of proceeds: “General corporate purposes,” with specifics including potential acquisition of additional ETH and other digital assets; expansion of staking and validator infrastructure (including through MAVAN); working capital; strategic investments aligned with Ethereum; and/or repurchases of common stock under BitMine’s buyback program. Key economics and investor protections - Dividend: cumulative, fixed at 9.50% per year on the $100 stated amount. Dividends accumulate whether or not declared, and when declared they’ll be paid in cash “when, as and if declared,” weekly in arrears. - Missed-dividend penalty: any unpaid accumulated regular dividend itself begins accruing additional dividends, compounded weekly. The compounded rate starts at 9.50% + 5 basis points (based on weekly periods) and rises by 5 bps each subsequent period until paid, capped at 15% per year. - Redemption rights: BitMine can redeem the preferred in whole or part for cash at 110% of stated amount during the first 18 months, 105% between 18 months and three years, and 100% after three years, plus any accumulated unpaid dividends. It may also redeem all outstanding shares if remaining shares fall below 25% of the original issuance or certain tax events occur. - Fundamental-change protection: holders can require BitMine to repurchase some or all shares for cash at the stated amount plus accumulated and unpaid regular dividends if a defined “fundamental change” occurs. Market mechanics and underwriters - Listing: BitMine has applied to list the preferred on the New York Stock Exchange under the ticker BMNP and expects trading to begin within 30 days after issuance if approved. - Joint lead bookrunners: Moelis & Company and Cantor. Context - The filing frames Ethereum as a reserve asset with an institutional-style wrapper: issue a yield-bearing security to attract investors, retain flexibility in using proceeds, and direct part of the capital into ETH and staking infrastructure. That mix targets investors seeking income while supporting BitMine’s strategy of building protocol-native revenue streams. At press time: ETH was trading around $1,793.
