(Nasdaq: VTYX) (“Ventyx”), a clinical-stage biopharmaceutical company focused on advancing novel oral therapies that address a range of inflammatory diseases with significant unmet medical need, announced today that it has entered into a stock purchase agreement for the sale of 11,174,000 shares of its common stock at an offering price of $8.95 per share in a private placement to certain qualified institutional buyers and institutional accredited investors. Gross proceeds of the private placement are expected to be approximately $100 million, before deducting placement agent fees and other expenses.

With the proceeds from the private placement, Ventyx expects to extend its cash runway into at least the second half of 2026.
