Canaan is turning part of the cryptocurrency produced and accumulated around its mining business into a different kind of capital allocation: buying back its own stock.

The Bitcoin mining hardware maker said it mined 44 BTC in August 2026 while maintaining 10.05 EH/s of non-joint-venture installed hashrate. Its joint ventures reached 4.92 EH/s of installed hashrate. Canaan reported an average all-in power cost of about $0.043 per kWh for the month.

Canaan converts part of its crypto treasury

The more unusual part of the August update was not the mining total. Canaan said it sold its entire 3,952 ETH position along with 54 BTC at average prices of roughly $2,400 per ETH and $79,000 per BTC. The sales generated approximately $13.9 million in cash.

The company then deployed about $5.4 million to repurchase approximately 13.6 million American Depositary Shares in late August. Combined with earlier repurchases, Canaan said it had bought back roughly 16.4 million ADSs for about $7.4 million during 2026 as of early September.

Canaan ended August with 1,868 BTC and no ETH on its balance sheet. The company says the asset sales do not represent an abandonment of its long-term digital-asset strategy.

Mining economics remain the foundation

The strategy highlights an important distinction for vertically integrated Bitcoin mining companies. A miner can allocate the Bitcoin it produces among several competing uses: retain BTC, fund operating and infrastructure expenses, invest in more efficient mining capacity, or convert part of the treasury into cash for corporate actions such as share repurchases.

For Canaan, power efficiency remains central to that equation. Its August update reported global non-JV average miner efficiency of 23.7 J/TH, while its North American non-JV fleet averaged 17.9 J/TH. The company reported 246.2 MW of global non-JV installed power capacity.

Those figures matter because electricity and machine efficiency determine how much economic flexibility a mining operation has after paying for power. Lower energy consumption per terahash can widen operating margins and give miners more options for the Bitcoin their fleets generate.

From ASIC manufacturer to compute and energy operator

Canaan is also continuing to broaden its infrastructure footprint. The company said computing equipment had arrived at its Canadian compute heat-recovery greenhouse project, with installation beginning ahead of the winter heating season.

The project is another example of miners experimenting with ways to reuse heat that would otherwise leave ASIC systems as waste energy. In colder climates, capturing that thermal output can potentially give mining infrastructure a second productive role.

Canaan’s August numbers therefore tell a larger story than a single month of Bitcoin production. The company is treating mining output, energy infrastructure, ASIC efficiency and its balance sheet as parts of the same capital system. The next question is whether that flexibility can translate into stronger economics as mining difficulty, Bitcoin price and hardware competition continue to change.
