Erasca, Inc. (ERAS) reported a major equity financing, announcing that on July 13, 2026 it entered into an underwriting agreement for a public offering of common stock. The company agreed to sell 31,428,572 shares of its common stock, par value $0.0001 per share, at a public offering price of $17.50 per share. The underwriting group is led by J.P. Morgan Securities LLC, Morgan Stanley & Co. LLC, Jefferies LLC and Evercore Group L.L.C., acting as representatives of the several underwriters. Under the agreement, the underwriters will purchase the shares from Erasca at $16.45 per share, reflecting underwriting discounts and commissions of $1.05 per share from the public offering price. At the public offering price, the base offering represents approximately $550.0 million in gross proceeds. Erasca said it expects net proceeds of approximately $516.0 million after underwriting discounts, commissions and estimated offering expenses. The company also granted the underwriters a 30-day option to purchase up to an additional 4,714,285 shares at the public offering price, less underwriting discounts and commissions. If that option is exercised in full, expected net proceeds would rise to approximately $593.5 million, and the total number of shares sold would be 36,142,857. The offering is expected to close on July 15, 2026, subject to customary closing conditions. Erasca said the transaction is being conducted under its shelf registration statement on Form S-3, which became effective automatically upon filing on July 13, 2026, along with a prospectus supplement and accompanying prospectus. The Form 8-K was filed under Item 8.01, “Other Events,” with Item 9.01 used to file related exhibits. Those exhibits include the underwriting agreement, a legal opinion from Latham & Watkins LLP regarding the legality of the share issuance, the firm’s consent, and Erasca’s July 13 press releases announcing the commencement and pricing of the offering. This filing reports a corporate financing transaction rather than an insider stock trade, so it does not include Form 4 transaction codes, insider ownership changes, vesting schedules or option exercise details. Erasca also included customary forward-looking statement language, noting that completion of the offering and expected proceeds remain subject to market conditions, customary closing conditions and other business risks.
