The Company completed a concurrent private placement to 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 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.
 
Warrants to purchase 5,850 shares of common stock were exercised during the year ended December 31, 2020.
On December 18, 2019, the Company completed an underwritten public offering of 2,565,000 shares of its common stock resulting in gross proceeds to the Company of approximately $10.0 million. On December 12, 2019, the Company completed an underwritten public offering of 3,715,000 shares of its common stock and a concurrent private placement of 1,111,111 shares of common stock to Pfizer Inc. resulting in total gross proceeds to the Company of approximately $13.0 million. The combined net proceeds of both public offerings together with the private placement was $21.3 million after underwriting discounts and commissions and offering expenses payable by the Company.
On August 3, 2018, the Company sold 575,000 shares of its common stock in an underwritten offering, including shares sold pursuant to the fully exercised overallotment option granted to the underwriters in connection with the offering, for gross proceeds of $11.5 million. The Company received net proceeds of approximately $10.4 million after underwriting discounts and commissions and offering expenses payable by the Company.
On July 25, 2017, the Company sold 3,200,000 shares of its common stock and warrants to purchase an additional 1,600,000 shares of its common stock in an underwritten offering for gross proceeds of $40 million (the “2017 Offering”). The Company received net proceeds of approximately $37.1 million after underwriting discounts and commissions and offering expenses payable by the Company.
On July 27, 2016, the Company sold 1,400,000 shares of its common stock and warrants to purchase an additional 1,400,000 shares of its common stock in an underwritten offering for gross proceeds of $35.0 million (the “2016 Offering”). The Company received net proceeds of approximately $32.0 million after underwriting discounts, commissions and offering expenses payable by the Company.
The Company issued warrants in the 2020, 2017 and 2016 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, the 2017 Warrants and the 2016 Warrants should be classified as liabilities in the Company’s consolidated balance sheet. At issuance, the Company determined the fair value of the 2020 Warrants, the 2017 Warrants and 2016 Warrants to be $31.4 million, $12.4 million and $18.6 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, $0.9 million and $1.6 million of issuance costs to the 2020 Warrants, the 2017 Warrants and 2016 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.
