The Company is authorized to issue one class of shares designated as “Common Stock”. The number of shares of common stock authorized to be issued is 217,000,000 shares.

Private Investment

On January 27, 2020, the Company entered into the Securities Purchase Agreement with Innoviva, pursuant to which the Company agreed to issue and sell to Innoviva, in the 2020 Private Placement, 8,710,800 newly issued shares of the Company’s common stock and warrants to purchase 8,710,800 shares of common stock, with an exercise price per share of $2.87. Each share of common stock was sold together with one common warrant granting the warrant holder the right to purchase an additional share of common stock (“Common Unit”) at $2.87 per share. The 2020 Private Placement occurred in two tranches. The first closing occurred on February 12, 2020, at which time Innoviva purchased 993,139 Common Units in exchange for an aggregate gross cash payment of approximately $2.8 million. On March 27, 2020, the second closing occurred subsequent to shareholder approval, at which time Innoviva purchased 7,717,661 Common Units in exchange for aggregate gross proceeds of $22.2 million.

The warrants expire five years from the issuance date. The Company reviewed the authoritative accounting guidance and determined that the warrants meet the criteria to be accounted for as permanent equity.

As described in more detail in Note 2, in January 2021, the Company entered into a securities purchase agreement with Innoviva for the 2021 Private Placement.
