2023 Private Placement

On July 21, 2023, we entered into a Securities Purchase Agreement (the “July 2023 Private Placement”) with Rubric Capital Management L.P., Velan Capital, Clearline Capital and Hercules Capital, Inc. (collectively, the “Purchasers”) whereby we sold 20.7 million shares of our common stock in a private placement at a purchase price of $1.37 per share. In addition, as a component of the July 2023 Private Placement, we sold 1.2 million pre-funded warrants to purchase shares of our common stock at a purchase price of $1.3699 per share (the "July 2023 Pre-Funded Warrants"). The July 2023 Pre-Funded Warrants have an exercise price of $0.0001 per share. The total net proceeds from the sale of the common stock and the July 2023 Pre-Funded Warrants is $29.8 million (net of $0.2 million in issuance costs). The July 2023 Private Placement closed on July 25, 2023. In August 2023, we filed a registration statement with the SEC to register for resale 21.9 million shares of our common stock. The registration statement was declared effective on August 31, 2023.
