The Company's amended and restated certificate of incorporation authorizes 125,000,000 shares of common stock, and 5,000,000 shares of undesignated preferred stock, both with a par value of $0.01 per share. There were no shares of undesignated preferred stock issued or outstanding as of December 31, 2023 or 2022.
In November 2020, the Company entered into a sales agreement (Sales Agreement) with an agent to sell, from time to time, shares of its common stock having an aggregate sales price of up to $100.0 million through an “at the market offering” (ATM Offering) as defined in Rule 415 under the Securities Act of 1933, as amended. The Company sold 3,622,186 shares of common stock resulting in net proceeds of approximately $98.2 million through December 31, 2021 under the Sales Agreement. In April 2021, the Company entered into Amendment No. 1 to the Sales Agreement which increased the amount of the Company’s common stock that can be sold by the Company through its agent under the ATM Offering, from an aggregate offering price of up to $100.0 million to an aggregate offering price of up to $300.0 million. During the year ended December 31, 2022, the Company sold 160,480 shares of common stock at a weighted average price per share of $6.87, resulting in net proceeds of approximately $1.1 million, net of underwriting discounts and commissions and other offering expenses. In March 2023, the Company terminated the Sales Agreement and entered into a new sales agreement with an agent to sell, from time to time, shares of its common stock having an aggregate sales price of up to $100.0 million through an ATM Offering. During the year ended December 31, 2023, the Company sold 95,000 shares of common stock at a weighted average price per share of $6.60, resulting in net proceeds of approximately $0.6 million, net of offering expenses.
