Note 7. Stockholders’ Equity

Common Stock Purchase Agreement

On March 4, 2019, the Company entered into a Purchase Agreement with Lincoln Park Capital Fund, LLC (“Lincoln Park”), which was amended on September 2, 2020 (as amended to date, the “LPC Purchase Agreement”), pursuant to which, upon the terms and subject to the conditions and limitations set forth therein, Lincoln Park committed to purchase an aggregate of $35.0 million of shares of Company common stock from time to time at the Company’s sole discretion over a 36-month period. As consideration for entering into the LPC Purchase Agreement, the Company issued 269,749 shares of Company common stock to Lincoln Park as a commitment fee (the “Commitment Shares”). The closing price of the Company’s common stock on March 4, 2019 was $2.84 and the Company did not receive any cash proceeds from the issuance of the Commitment Shares.

During the three months ended March 31, 2022, the Company did not sell any shares under the LPC Purchase Agreement. The 36-month period noted above for the LPC Purchase Agreement expired on March 4, 2022; accordingly, the Company no longer has access to additional capital under the LPC Purchase Agreement subsequent to this date.

During the three months ended March 31, 2021, the Company sold 800,000 shares, pursuant to the LPC Purchase Agreement, resulting in net proceeds of $4.2 million.

"At-The-Market" Equity Program

In November 2018, the Company entered into an Equity Distribution Agreement (the “ATM Agreement”) with JMP Securities LLC (“JMP”) pursuant to which the Company may issue and sell shares of its common stock having an aggregate offering price of up to $50.0 million (the “Shares”) through JMP as its agent. Subject to the terms and conditions of the ATM Agreement, JMP will use its commercially reasonable efforts to sell the Shares from time to time, based upon the Company’s instructions, by methods deemed to be an “at the market offering” as defined in Rule 415(a)(4) promulgated under the Securities Act of 1933, as amended, or if specified by the Company, by any other method permitted by law, including but not limited to in negotiated transactions. The Company has no obligation to sell any of the Shares, and the Company or JMP may at any time suspend sales under the ATM Agreement or terminate the ATM Agreement. JMP is entitled to a fixed commission of 3.0% of the gross proceeds from Shares sold.

During the three months ended March 31, 2022, the Company sold no shares of common stock pursuant to the ATM Agreement.

During the three months ended March 31, 2021, the Company sold 2,394,956 shares of common stock, pursuant to the ATM Agreement resulting in net proceeds, after deduction of commissions and other offering expenses, of $12.1 million. As of March 31, 2022, the Company may sell up to an additional $19.5 million of shares under the ATM Agreement, subject to applicable securities laws and related rules and regulations.

July 2020 Private Placement

On July 13, 2020, the Company entered into a Securities Purchase Agreement (the “July 2020 Securities Purchase Agreement”) with Pillar Partners Foundation, L.P. (“Pillar Partners”), Pillar Pharmaceuticals 6, L.P. (“Pillar 6”), and Pillar Pharmaceuticals 7 L.P. (“Pillar 7”) (collectively, the “July 2020 Purchasers”), each a related party as more fully described in Note 10, pursuant to which, among other things, provided the July Purchasers the option to purchase, at their sole discretion, pre-funded warrants to purchase up to 784,615 shares of the Company’s common stock, at an exercise price of $0.01 per share, and warrants to purchase up to 274,615 shares of the Company’s common stock, at an exercise price of $9.75, for aggregate gross proceeds of $5.1 million (the “July 2020 Private Placement Second Closing”). During the three months ended March 31, 2021, the option to purchase securities in the July 2020 Private Placement Second Closing terminated. As a result, the Company is no longer eligible to receive additional proceeds from the sale of additional securities pursuant to the July 2020 Securities Purchase Agreement. However, the July 2020 Purchasers still hold outstanding warrants previously issued under the July 2020 Securities Purchase Agreement, as detailed below under the heading “Common Stock Warrants”.
