Stockholder's Equity

9. Stockholder's Equity

In August 2020, we entered into an at-the-market offering program, or “ATM”, which provides for the offering, issuance and sale by us of shares of our common stock from time to time for aggregate gross proceeds of up to $200.0 million. In the six months ended June 30, 2022, we have sold and issued 2,065,358 shares of common stock pursuant to the ATM, with total gross proceeds of $50.0 million before deducting underwriting discounts, commissions, and other offering expenses payable by us of $1.5 million.
