BRISBANE, Calif., July 30, 2024 (GLOBE NEWSWIRE) — Day One Biopharmaceuticals, Inc. (Nasdaq: DAWN) (“Day One” or the “Company”), a commercial-stage biopharmaceutical company dedicated to developing and commercializing targeted therapies for people of all ages with life-threatening diseases, today announced it has entered into a securities purchase agreement for an oversubscribed private placement of its securities for gross proceeds of approximately $175.0 million, before deducting placement agent fees and other expenses.

The private placement includes participation from both new and existing investors including Fairmount, Braidwell LP, Deerfield Management, Wellington Management, Frazier Life Sciences and Access Biotechnology, as well as large investment management firms and several healthcare dedicated funds.

The private placement will be for 10,551,718 shares of common stock at a price of $14.50 per share. In lieu of shares of common stock, certain investors purchased 1,517,241 pre-funded warrants at a purchase price of $14.4999 per pre-funded warrant, which equals the purchase price per share of common stock, less the $0.0001 per share exercise price of each pre-funded warrant.

The private placement is expected to close on August 1, 2024, subject to the satisfaction of customary closing conditions. The Company intends to use the proceeds from the private placement, together with its existing cash, cash equivalents and short-term investments, to fund investment in its commercial capabilities, continued research and development activities, potential strategic acquisitions or licensing of complementary businesses or technologies, working capital and other general corporate purposes.

J.P. Morgan, TD Cowen, Goldman Sachs & Co. LLC and Piper Sandler are acting as joint placement agents for the private placement.
