This public company quit solar for a $5 million Bitcoin bet, now it has just $166,000 in cash

Sono Group’s latest filing highlights severe liquidity stress after pivoting from solar into a Bitcoin-heavy treasury strategy. The company reported just $166,000 in cash at June 30 against $4.118 million in Bitcoin, while generating no continuing-operations revenue in the first half of 2026. Sono spent $5 million to buy 68.49 BTC and ended June with 69.78 BTC, but still recorded an $890,000 digital-asset treasury loss and a $5.792 million net loss overall. Management is using weekly covered calls on Bitcoin to raise cash, generating $93,000 of option income, but the filing says that may not be enough to cover obligations. Sono has also raised $7.050 million in financing this year and carries $5.049 million in convertible notes payable. The key market implication is that Bitcoin is no longer just a treasury asset for Sono—it is becoming a potential source of emergency liquidity amid ongoing going-concern risk.
