Confidential Submission of the Draft Registration Statement on Form F-1

On behalf of our client, Canaan Inc., an exempted company incorporated under the laws of the Cayman Islands with limited liability (the “Company”), we hereby submit a draft Registration Statement on Form F-l (the “Draft Registration Statement”) relating to the proposed initial public offering in the United States of the Company’s ordinary shares to be represented by American depositary shares (“ADSs”). The ADSs are expected to be listed either on the New York Stock Exchange or the NASDAQ.

The Draft Registration Statement is submitted via EDGAR to the Securities and Exchange Commission (the “Commission”) for review on a confidential basis pursuant to the Jumpstart Our Business Startups Act (the “JOBS Act”). The Company confirms that it is an “Emerging Growth Company” as defined in the JOBS Act and its securities have not been previously sold pursuant to an effective registration statement under the Securities Act of 1933, as amended. A registration statement on Form F-6 relating to the Company’s ADSs will be filed with the Commission in due course.

As an Emerging Growth Company, the Company has included in the Draft Registration Statement its audited financial statements as of December 31, 2017 and 2018 and for the years ended December 31, 2017 and 2018.

If you have any question regarding the Draft Registration Statement, please do not hesitate to contact me at +852-2514-7650 (work), +852-9198-4235 (mobile) or clin@stblaw.com (email).
