Public Company Sono Shifts to Bitcoin Treasury, Holds $4.1M BTC Against $166K Cash

Sono Group’s transition to a Bitcoin-heavy treasury is laying bare the severe financial strain at the core of the restructured company.

With its former solar energy subsidiary now spun out as a discontinued operation, the parent company generated zero revenue during the first half of 2026. Instead, Sono has tethered its survival entirely to digital assets.

However, an Aug. 14 Form 10-Q filing reveals a stark liquidity mismatch: as of June 30, the company held just $166,000 in cash against $4.11 million in Bitcoin.

Bitcoin sits at the center of Sono’s liquidity plan

Bitcoin now occupies a central position in Sono’s continuing business accounts.

During the first six months of the year, the company spent $5 million to acquire 68.49 BTC. After accounting for option-related receipts and deliveries, its treasury stood at 69.78 BTC by the end of June. The firm stated that the fair value of these holdings stands at $4.118 million.

However, the strategy has yet to pay off as the company recorded an $890,000 net digital-asset treasury loss for the half.

To generate additional liquidity from the reserve, management has been writing weekly covered calls against its Bitcoin holdings. This strategy produced $93,000 of net option income during the first half, but the filing warns that those proceeds may not be sufficient to meet the company’s obligations.
