FibroGen, Inc. (“FibroGen” or the “Company”) was incorporated in 1993 in Delaware and is a research-based biopharmaceutical company focused on the discovery, development and commercialization of novel therapeutics agents to treat serious unmet medical needs. The Company’s focus in the areas of fibrosis and hypoxia-inducible factor (“HIF”) biology has generated multiple programs targeting various therapeutic areas. The Company’s most advanced product candidate, roxadustat, or FG-4592, is an oral small molecule inhibitor of HIF prolyl hydroxylases (“HIF-PHs”) in Phase 3 clinical development for the treatment of anemia in chronic kidney disease (“CKD”). FG-3019 is the Company’s monoclonal antibody in Phase 2 clinical development for the treatment of idiopathic pulmonary fibrosis (“IPF”), pancreatic cancer, Duchenne muscular dystrophy (“DMD”) and liver fibrosis. The Company has taken a global approach with respect to the development and future commercialization of its product candidates, and this includes development and commercialization in the People’s Republic of China (“China”). On November 19, 2014, the Company closed the initial public offering (“IPO”) of its common stock. In its IPO, the Company sold 9,315,000 shares of its common stock at a public offering price of $18.00 per share. Net proceeds from the Company’s IPO and concurrent private placement were $171.8 million, after deducting underwriting discounts and commissions of $11.7 million and offering expenses of $4.1 million. Concurrent with the closing of the IPO, AstraZeneca AB (“AstraZeneca”), one of the Company’s collaboration partners, purchased shares of FibroGen common stock in a private placement at a price per share equal to the IPO price for an aggregate purchase price of $20.0 million. Upon the closing of the IPO, all outstanding shares of the Company’s convertible preferred stock automatically converted into 33,919,954 shares of common stock and 958,996 shares of FibroGen Europe convertible preferred stock were converted into shares of FibroGen common stock. The Company’s proceeds from the sale of the common stock sold in the concurrent private placement were $20.0 million.
