Bitmine Plans 9.5% Preferred Stock Plan to Fuel Its Ethereum Buying Spree

Bitmine has applied to list the shares on the NYSE under the symbol BMNP.

Ethereum treasury company Bitmine has filed to launch a public offering of 3 million shares of its 9.50% Series A Perpetual Preferred Stock.

The proceeds are expected to support a range of corporate and Ethereum-focused initiatives.

Bitmine’s New Offering

According to the company’s filing with the Securities and Exchange Commission (SEC), the net funds raised may be used for general corporate purposes, including the acquisition of additional ETH and other digital assets, the expansion of its staking and validator infrastructure through its MAVAN platform, working capital requirements, strategic investments tied to the Ethereum ecosystem and broader digital asset adoption, and potential repurchases of its common stock under an existing buyback program.

The preferred shares will carry cumulative dividends at a fixed annual rate of 9.50% based on a stated value of $100 per share. The dividends are payable in cash when declared by the company’s board. If any declared dividend is not paid on schedule, additional compounded dividends will accrue weekly, and the applicable rate will gradually increase up to a maximum of 15% per year until the outstanding amount is fully settled.

Bitmine has applied to list the new preferred shares on the New York Stock Exchange under the ticker symbol “BMNP,” and trading is expected to begin within 30 days of the initial issuance if the listing receives approval.

Interestingly, Bitmine’s application is based on a model similar to Saylor-led Strategy’s STRC perpetual preferred stock, which pays an 11.5% dividend. STRC has attracted investors looking for monthly income while gaining indirect exposure to Bitcoin. After raising around $2.52 billion through its initial public offering in July 2025, the program expanded through follow-on issuances. The total notional amount of STRC is approximately $10.5 billion.

Aggressive ETH Accumulation

With its Ethereum holdings rising to 5.42 million ETH, Bitmine said it has reached roughly 90% of its target to own 5% of all ETH. The company also said 4.72 million ETH are staked, with a portion of those assets secured through its MAVAN staking platform.

As one of the sector’s most active buyers, Bitmine has built the largest ETH treasury and the second-largest overall crypto treasury after Strategy. The sharp drop in Ethereum, which is down more than 45% year to date, has created significant challenges for Ethereum treasury companies. Recent data estimates indicate that Bitmine is carrying unrealized losses of more than $10 billion.

Even so, Chairman and Fundstrat co-founder Tom Lee remains optimistic on Ethereum, as he predicted the end of the bull market and the beginning of crypto spring.
