**Canaan Inc. Renews Its US$30 Million Share Buyback Program**

*Renewal demonstrates confidence in the Company's long-term value and strategic progress*

SINGAPORE, December 17, 2025 /PRNewswire/ -- Canaan Inc. (NASDAQ: CAN) ("Canaan" or the "Company"), an innovator in crypto mining, today announced that its board of directors (the "Board") has authorized a share repurchase program under which the Company may buy back up to US$30 million worth of its outstanding American depositary shares ("ADSs"), each representing 15 Class A ordinary shares, or Class A ordinary shares, over the next 12 months starting December 12, 2025. This initiative underscores the Company's strong financial position, solid operational performance in the third quarter of 2025, and confidence in its ability to create long-term shareholder value.

The Company's previously announced share repurchase program of up to US$30 million over a six-month period, beginning May 27, 2025 (the "Previous Program"), had expired. Under the Previous Program, the Company had repurchased 6,586,413 ADSs for a total of approximately US$4.9 million, including 1,505,314 ADSs repurchased for approximately US$1.5 million between November 19 and November 27 following the announcement of its unaudited financial results for the third quarter 2025 on November 18, 2025.

Nangeng Zhang, chairman and chief executive officer of Canaan, commented, "We think the current market valuation does not capture the progress we have made in strengthening our business. Compared with our publicly listed Bitcoin mining peers, Canaan's valuation remains at the more conservative end relative to its operating footprint. Against a backdrop of continued macroeconomic and industry volatility, we delivered encouraging improvements in our third-quarter performance, expanded global customer engagement, and enhanced product innovation and mining operations. This buyback program reflects our disciplined approach to capital allocation and our unwavering commitment to creating enduring value for our shareholders."

Under the share repurchase program, the Company may repurchase the ADSs representing its Class A ordinary shares through open market transactions at prevailing market prices, privately negotiated transactions, block trades, or any combination thereof. Canaan will execute the repurchase transactions in compliance with the Securities Exchange Act of 1934, as amended, and its insider trading policy. The number of ADSs repurchased and the timing of repurchases will depend on a number of factors, including, but not limited to, price, trading volume, and general market conditions, along with Canaan's working capital requirements and general business conditions. The Company's Board or its management will review the share repurchase program periodically and may authorize an adjustment of its terms and size as appropriate. The Company plans to fund the repurchases with its existing cash balance.
