Bitmine Immersion Technologies, the cryptocurrency-focused company chaired by market strategist Tom Lee, said in a supplementary prospectus that it may sell up to $24.5 billion of common stock through an at-the-market program. The figure supersedes an earlier plan to raise as much as $20 billion, according to the document filed with the U.S. Securities and Exchange Commission. Proceeds from the share sales are earmarked for the purchase of additional Ethereum, reinforcing Bitmine Immersion’s strategy of holding the digital asset on its corporate balance sheet. The company did not specify a timetable for the issuance, noting that shares may be sold from time to time depending on market conditions. BMNR shares slipped about 2% in pre-market trading after the expanded shelf registration was disclosed.
