8. Pre-Funded Warrants
In February 2020, the Company completed the February Offering, which included the issuance and sale of pre-funded warrants to purchase 2,884,615 shares of its common stock. The public offering price of the pre-funded warrants was $2.599 per underlying share.
In June 2020, the Company completed the June Offering, which included the issuance and sale of pre-funded warrants to purchase 909,091 shares of its common stock. The public offering price of the pre-funded warrants was $5.499 per underlying share.
Each pre-funded warrant entitles the holder to purchase shares of common stock at an exercise price of $0.001 per share and expires 20 years from the date of issuance. These warrants were recorded as a component of stockholders’ equity within additional paid-in capital. Per the terms of the warrant agreement, a holder of the outstanding warrant is not entitled to exercise any portion of the pre-funded warrant if, upon exercise of such portion of the warrant, the holder’s ownership of our common stock (together with its affiliates) or the combined voting power of our securities beneficially owned by such holder (together with its affiliates) would exceed 4.99% after giving effect to the exercise (“Maximum Ownership Percentage”). Upon at least 61 days’ prior notice to us by the warrant holder, any
warrant holder may increase or decrease the Maximum Ownership Percentage to any other percentage not to exceed 19.99%. As of December 31, 2020, no shares underlying the pre-funded warrants have been exercised.
The following table represents a summary of the pre-funded warrants outstanding as of December 31, 2020.
