This was previously reported in the Company&#8217;s definitive proxy statement for the Company&#8217;s annual meeting of stockholders held on June 4, 2025 (the &#8220;2025 Annual Meeting&#8221;), as filed with the Securities and Exchange Commission on April 25, 2025 (the &#8220;Proxy Statement&#8221;).

After receiving notice from Nasdaq on March 12, 2025 that FibroGen did not regain compliance with the Minimum Bid Price Requirement, FibroGen appealed this determination on March 14, 2025, as previously disclosed in the Company's Form 8-K filed on March 17, 2025. On April 11, 2025, the Nasdaq Hearings Panel granted the Company a temporary exception to regain compliance with the Minimum Bid Price Requirement, contingent on obtaining stockholder approval on June 4, 2025, and thereafter effecting a reverse stock split by June 24, 2025.</span></p><p style="font-size:10pt;margin-top:0;font-family:Times New Roman;margin-bottom:6pt;text-align:left;"><span style="color:#000000;white-space:pre-wrap;font-size:10pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">Upon the Effective Time of the Certificate of Amendment with the Secretary of State of the State of Delaware, each Twenty-Five (25) shares of Common Stock issued immediately prior to the Effective Time shall, automatically and without any action on the part of the respective holders thereof, be reclassified and combined into one (1) share of Common Stock. No fractional shares shall be issued and, in lieu thereof, any holder of less than one (1) share of Common Stock shall be entitled to receive cash for such holder&#8217;s fractional share based upon the closing sales price of the Common Stock as reported on The Nasdaq Global Select Market on the date that the Certificate of Amendment becomes effective.

(NASDAQ: FGEN) today announced that it will implement a 1-for-25 reverse stock split of its issued and outstanding common stock (&#34;Reverse Stock Split&#34;), effective at 5:00 p.m. Eastern Time on June 16, 2025.  FibroGen&#x2019;s common stock will begin trading on a split-adjusted basis on June 17, 2025, when the markets open, under the Company&#x2019;s existing trading symbol &#x201c;FGEN,&#x201d; with the new CUSIP number 31572Q881.</font></p><p style="font-size:10pt;margin-top:0;font-family:Times New Roman;margin-bottom:8pt;text-align:left;"><font style="color:#000000;white-space:pre-wrap;font-size:12pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">The Reverse Stock Split was previously approved by stockholders at the Company&#x2019;s annual meeting of stockholders held on June 4, 2025 (&#x201c;2025 Annual Meeting&#x201d;), with the final ratio determined by the Company&#x2019;s Board of Directors. One of the primary goals of the Reverse Stock Split is to increase the per-share market price of FibroGen&#x2019;s common stock to regain compliance with the minimum bid price requirement for continued listing on the Nasdaq Global Select Market (Nasdaq Listing Rule 5450(a)(1)).</font></p><p style="font-size:10pt;margin-top:0;font-family:Times New Roman;margin-bottom:0;text-align:left;"><font style="color:#000000;white-space:pre-wrap;font-size:12pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">At the effective time of the Reverse Stock Split, every 25 shares of the Company&#x2019;s issued and outstanding common stock will automatically be reclassified and combined into one share of the Company&#x2019;s common stock. This will reduce the number of issued and outstanding shares of common stock from approximately 101.1 million shares to approximately 4.0 million shares. Proportionate adjustments will be made to the number of shares available for issuance under the Company&#x2019;s equity incentive plans as well as outstanding equity awards, in accordance with their respective terms and as described in the Company's definitive proxy statement for the 2025 Annual Meeting (the &#34;Proxy Statement&#34;).  No fractional shares will be issued as a result of the Reverse Stock Split. Stockholders who would otherwise be entitled to a fractional share will instead receive a cash payment in lieu of such fractional share.</font></p><p style="font-size:10pt;margin-top:0;font-family:Times New Roman;margin-bottom:0;text-align:left;"><font style="white-space:pre-wrap;font-size:12pt;font-family:'Calibri',sans-serif;font-kerning:none;min-width:fit-content;">&#160;</font></p><p style="font-size:10pt;margin-top:0;font-family:Times New Roman;margin-bottom:8pt;text-align:left;"><font style="color:#000000;white-space:pre-wrap;font-size:12pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">Equiniti Trust Company, LLC is acting as the exchange agent and transfer agent for the Reverse Stock Split. Stockholders holding their shares electronically are not required to take any action to receive post-split shares. Stockholders owning shares through a bank, broker or other nominee will have their positions adjusted to reflect the Reverse Stock Split and will receive payment for any fractional shares in accordance with their respective bank's, broker's, or nominee's particular processes. Additional information about the Reverse Stock Split can be found in the Proxy Statement and on the Company&#x2019;s Investor Relations website at https://investor.fibrogen.com</font><font style="color:#0563c1;white-space:pre-wrap;font-size:12pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">.</font></p><p style="font-size:10pt;margin-top:0;font-family:Times New Roman;margin-bottom:8pt;text-align:left;"><font style="white-space:pre-wrap;font-size:12pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">&#160;</font></p><p style="font-size:10pt;margin-top:0;font-family:Times New Roman;margin-bottom:0;text-align:left;"><font style="white-space:pre-wrap;font-size:12pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">&#160;</font></p><p style="font-size:10pt;margin-top:0;font-family:Times New Roman;margin-bottom:0;text-align:left;"><font style="white-space:pre-wrap;font-size:12pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">&#160;</font></p><p style="font-size:10pt;margin-top:0;font-family:Times New Roman;margin-bottom:0;text-align:left;"><font style="white-space:pre-wrap;font-size:12pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">&#160;</font></p><p style="font-size:10pt;margin-top:0;font-family:Times New Roman;margin-bottom:0;text-align:left;"><font style="white-space:pre-wrap;font-size:12pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">&#160;</font></p><p style="font-size:10pt;margin-top:0;font-family:Times New Roman;margin-bottom:0;text-align:left;"><font style="white-space:pre-wrap;font-size:12pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">&#160;</font></p><p style="font-size:10pt;margin-top:0;font-family:Times New Roman;margin-bottom:0;text-align:left;"><font style="white-space:pre-wrap;font-size:12pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">&#160;</font></p><p style="font-size:10pt;margin-top:0;font-family:Times New Roman;margin-bottom:0;text-align:left;"><font style="white-space:pre-wrap;font-size:12pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">&#160;</font></p><p style="font-size:10pt;margin-top:0;font-family:Times New Roman;margin-bottom:0;text-align:left;"><font style="white-space:pre-wrap;font-size:10pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">&#160;</font></p></div>
