On August 9, 2024, the Company entered into an underwriting agreement with Leerink Partners LLC and Evercore Group L.L.C., as representatives of the several underwriters named therein, in connection with an underwritten public offering (the “August 2024 Offering”) of (i) 9,285,511 Common Shares (the “Shares”), and (ii) to certain investors, pre-funded warrants (the “Pre-Funded Warrants”) to purchase 1,428,775 Common Shares (the "Pre-Funded Warrant Shares"). The offering price for the Shares was $7.00 per share, less underwriting discounts and commissions. The offering price for the Pre-Funded Warrants was $6.999 per Pre-Funded Warrant, less underwriting discounts and commissions, which represents the per share public offering price for the Shares less a $0.001 per share exercise price for each such Pre-Funded Warrant.

The net proceeds to the Company from the August 2024 Offering were approximately $70.0 million, after deducting underwriting discounts and commissions and other offering expenses payable by the Company. The August 2024 Offering closed on August 12, 2024.

The Company intends to use the net proceeds from the August 2024 Offering to fund the research and development of its product candidates and for working capital and general corporate purposes.

The Pre-Funded Warrants are exercisable at any time after the date of issuance. The exercise price and the number of Pre-Funded Warrant Shares are subject to appropriate adjustment in the event of certain share dividends and distributions, share splits, share combinations, reclassifications or similar events affecting the Common Shares as well as upon any distribution of assets, including cash, securities or other property, to the Company’s shareholders. The Pre-Funded Warrants will not expire and are exercisable in cash or by means of a cashless exercise. A holder of Pre-Funded Warrants may not exercise such Pre-Funded Warrants if the aggregate number of Common Shares beneficially owned by such holder, together with its affiliates, would exceed more than 4.99% or 9.99% (at the initial election of the holder) of the number of Common Shares outstanding following such exercise, as such percentage ownership is determined in accordance with the terms of the Pre-Funded Warrants. A holder of Pre-Funded Warrants may increase or decrease this percentage not in excess of 19.99% by providing at least 61 days’ prior notice to the Company.
