Common Stock
We are authorized to issue 200,000,000 shares of common stock. Common stockholders are entitled to dividends if and when declared by our board of directors. As of June 30, 2026, no dividends on common stock had been declared by us.
On May 10, 2022, we entered into a Sales Agreement (the “Sales Agreement”) with Leerink Partners LLC (“Leerink Partners”), pursuant to which we are entitled to offer and sell shares of our common stock (the “ATM Offering”). The Sales Agreement provides that Leerink Partners will be entitled to a sales commission equal to 3.0% of the gross sales price per share of all shares sold under the ATM Offering. We were initially entitled to offer and sell shares of our common stock having an aggregate offering price of up to $50.0 million in the ATM Offering, which was subsequently increased in February 2024 to $75.0 million. On May 8, 2025, we filed a new Registration Statement on Form S-3 and filed a new prospectus covering the ATM Offering (the “Prospectus”) for the offer and sale of shares of our common stock with an aggregate offering price of up to $12.5 million in the ATM Offering as a result of being subject to General Instruction I.B.6 of Form S-3 (the “Baby Shelf Limitation”). As of June 30, 2026, we remain subject to the Baby Shelf Limitation. During the six months ended June 30, 2026, we did not sell any shares of our common stock under the ATM Offering. During the six months ended June 30, 2025, we sold 421,766 shares of our common stock at an average price of $1.33 per share for net proceeds of $0.3 million after deducting sales commissions and offering expenses.
