Bitmine ups $4B buyback

Bitmine Immersion Technologies raised its stock buyback authorization to $4 billion as it moved its shares to the New York Stock Exchange on April 9. (sec.gov) The company said the new authorization is up from a $1 billion repurchase plan its board approved on July 29, 2025. Bitmine said the buyback remains open-ended and can be carried out in the market or through negotiated transactions. (sec.gov) A stock buyback lets a company use cash to purchase its own shares, reducing the number of shares left in public hands. Bitmine Chairman Thomas “Tom” Lee said on April 9 that the company wanted the flexibility to retire stock if shares trade below what it sees as intrinsic value. (marketwatch.com) Bitmine paired the buyback expansion with an exchange move from NYSE American to the main New York Stock Exchange, while keeping the BMNR ticker. The April 9 filing lists Bitmine common stock as registered on the New York Stock Exchange under Section 12(b) of the Securities Exchange Act. (sec.gov) The company has changed sharply since last summer, when it described itself in a June 2025 securities filing as focused on accumulating bitcoin from mining and capital raises. By April 9, 2026, Bitmine was describing itself as the world’s largest holder of Ethereum and said it owned about 4.803 million Ether as of April 6. (sec.gov, sec.gov) That matters for the buyback because Bitmine is no longer being pitched only as a mining company. In the same April 9 announcement, Bitmine said its crypto, cash and “moonshots” holdings totaled $11.4 billion, including $864 million in cash, and tied the repurchase plan to its broader capital allocation strategy. (sec.gov) Bitmine’s earlier $1 billion buyback announcement made that link more directly. Lee said on July 29, 2025 that, in pursuit of the company’s goal of owning 5% of Ethereum supply, there could be times when buying Bitmine shares offered a better expected return than buying more crypto. (sec.gov) The company’s own disclosures frame the exchange move as a credibility step as it courts larger investors. Its April 9 release said the company remained backed by investors including ARK, Founders Fund, Pantera, Kraken, Digital Currency Group and Galaxy Digital. (sec.gov) Bitmine’s latest filing does not say how quickly it will spend the full $4 billion, and buyback authorizations are not the same as completed repurchases. What it does show is that Bitmine entered the New York Stock Exchange with a much larger mandate to support its stock while it keeps building an Ethereum-heavy balance sheet. (sec.gov)
