Form 10-K filed March 1, 2021 Cover Page 1. At the onset of Part 1, provide prominent disclosure that you are not a Chinese operating company but a United States holding company with operations conducted by your subsidiary and through contractual arrangements with a variable interest entity (VIE) based in China and that this structure involves unique risks to investors. Explain whether the VIE structure is used to replicate foreign investment in Chinese-based companies where Chinese law prohibits direct foreign investment in the operating companies, and disclose that investors may never directly hold equity interests in the Chinese operating company. Your disclosure should acknowledge that Chinese regulatory authorities could disallow this structure, which would likely result in a material change in your operations and/or value of your common stock, including that it could cause the value of such securities to significantly decline or become worthless. Provide a cross-reference to your detailed discussion of risks facing the company as a result of this structure.

Your Business section should address, but not necessarily be limited to, the risks highlighted in Part 1. 3.

Refrain from using terms such as we or our when describing activities or functions of a VIE. Disclose clearly the entity (including the domicile) in which investors are purchasing their interest. 4.

Disclose your intentions to distribute earnings or settle amounts owed under the VIE agreements.

Describe any restrictions and limitations on your ability to distribute earnings from your businesses, including subsidiaries and/or VIEs, to the parent company and U.S. investors as well as the ability to settle amounts owed under the VIE agreements.

Disclose the uncertainties regarding the status of the rights of the United States holding company with respect to its contractual arrangements with the VIE, its founders and owners, and the challenges the company may face enforcing these contractual agreements due to uncertainties under Chinese law and jurisdictional limits. 6. In your summary of risk factors, disclose the risks that your corporate structure and being based in or having a significant portionof the company s operations in China poses to investors. In particular, describe the significant regulatory, liquidity, and enforcement risks with cross-references to the more detailed discussion of these risks . For example, specifically discuss risks arising from the legal system in China, including risks and uncertainties regarding the enforcement of laws and that rules and regulations in China can change quickly with little advance notice; and the risk that the Chinese government may intervene or influence your operations at any time, or may exert more control over offerings conducted overseas and/or foreign investment in China-based issuers, which could result in a material change in your operations and/or the value of your common stock. Acknowledge any risks that any actions by the Chinese government to exert more oversight and control over offerings that are conducted overseas and/or foreign investment in China-based issuers could significantly limit or completely hinder your ability to offer or continue to offer securities to investors and cause the value of such securities to significantly decline or be worthless. 7. On page 1 and as a separate risk factor under Item 1A, disclose each permission that you or your subsidiaries are required to obtain from Chinese authorities to operate and issue these securities to foreign investors, including approvals needed to transfer scientific data.

Revise for the consequences to you and your investors if you do not receive or maintain the approvals, inadvertently conclude that such approvals are not required, or applicable laws, regulations, or interpretations change and you are required to obtain approval in the future. Item 1A. Risk Factors, page 49 8. Revise your risk factors to acknowledge that if the PRC government determines that the contractual arrangements constituting part of your VIE structure do not comply with PRC regulations, or if these regulations change or are interpreted differently in the future, your shares may decline in value or become worthless if you are unable to assert your contractual control rights over the assets of your PRC subsidiaries that conduct a significant portion of your operations. 9. Given the Chinese government s significant oversight and discretion over the conduct of Pat Cotroneo FIBROGEN INC November 8, 2021 Page 4 your business, please revise to separately highlight the risk that the Chinese government may intervene or influence your operations at any time, which could result in a material change in your operations and/or the value of your common stock. 10.
