8. Capital Structure Common Stock As of June 30, 2022, the Company was authorized to issue 125,000,000 shares of common stock. Follow-on Offerings On March 22, 2021, the Company completed an underwritten public offering of 11,500,000 shares of its common stock, including shares sold pursuant to the fully exercised overallotment option granted to the underwriters in connection with the offering, at a public offering price of $5.00 per share, resulting in net proceeds to the Company of approximately $53.8 million after underwriting discounts and commissions and offering expenses payable by the Company. On May 27, 2020, the Company completed an underwritten public offering of 11,797,752 shares of its common stock and warrants to purchase an additional 8,848,314 shares of its common stock at an exercise price of $4.90 per share. The public offering price was $4.45 for one share of common stock and an accompanying warrant to purchase 0.75 shares of common stock, resulting in net proceeds to the Company of approximately $48.9 million after underwriting discounts and commissions and offering expenses payable by the Company. The Company completed a concurrent private placement to Pfizer Inc. (“Pfizer”) of 674,156 shares of common stock and an accompanying warrant to purchase an additional 505,617 shares of its common stock at an exercise price of $4.90 per share (the “Pfizer Warrant”) at a price of $4.45 for one share of common stock and an accompanying warrant to purchase 0.75 shares of common stock, resulting in net proceeds to the Company of approximately $3.0 million. No warrants were exercised during the six months ended June 30, 2022. Warrants to purchase 22,560 shares of common stock were exercised during the six months ended June 30, 2021. The Company issued warrants in its 2020 and 2017 offerings. These warrants contain a fundamental transaction provision that obligates the Company to cash settle the warrants under a limited set of conditions not entirely within the Company’s control. Due to this conditional obligation, the Company determined that the 2020 Warrants and the 2017 Warrants classified as liabilities in the Company’s consolidated balance sheet. At issuance, the Company determined the fair value of the 2020 Warrants and the 2017 Warrants to be $31.4 million and $12.4 million, respectively, and reclassified these balances from stockholders’ equity to warrant liability. The fair value of these warrants is
re-measured at each reporting period and changes in fair value are recognized in the consolidated statement of operations (see Note 4, “Fair Value Measurements”). Additionally, the Company allocated approximately $2.2 million and $0.9 million of issuance costs to the 2020 Warrants and the 2017 Warrants, respectively, based on the proportion of the proceeds allocated to the fair value of the warrants. The allocated issuance costs were expensed as other expense in the Company’s consolidated statement of operations. The Pfizer Warrant does not contain the same fundamental transaction provision that obligates the Company to cash settle the warrants under a limited set of conditions not entirely within the Company’s control. Therefore, the Company determined that the Pfizer Warrant should be classified as equity in the Company’s consolidated balance sheet. Voting The holders of shares of common stock are entitled to one vote for each share of common stock held at all meetings of stockholders and written actions in lieu of meetings. Dividends The holders of shares of common stock are entitled to receive dividends, if and when declared by the board of directors. As of June 30, 2022, no dividends have been declared or paid on the Company’s common stock since inception. Reserved for Future Issuance The Company has reserved for future issuance the following number of shares of common stock as of June 30, 2022 and December 31, 2021:
