New York, New York--(Newsfile Corp. - August 6, 2026) - Faruqi & Faruqi, LLP , a leading national securities law firm, is investigating potential claims against Erasca, Inc. ("Erasca" or the "Company") (NASDAQ: ERAS) and reminds investors of the August 10, 2026 deadline to seek the role of lead plaintiff in a federal securities class action that has been filed against the Company.

Faruqi & Faruqi is a leading national securities law firm with offices in New York, Pennsylvania, California and Georgia. The firm has recovered hundreds of millions of dollars for investors since its founding in 1995. See www.faruqilaw.com .

As detailed below, the complaint alleges that the Company and its executives violated federal securities laws by making false and/or misleading statements and/or failing to disclose that: 1) ERAS-0015's preclinical data was based on improper comparisons to Revolution Medicines, Inc. ("RevMed") and placed Erasca at risk of violating patent and trade secret protections; and (2) based on the foregoing, Defendants lacked a reasonable basis for their positive statements related to ERAS-0015.

On April 27, 2026, before the market opened, Erasca disclosed in a Form 8-K that it had received a letter from legal counsel for RevMed alleging that Erasca's ERAS-0015 infringes a RevMed patent (U.S. Patent No. 12,409,225) and is connected to alleged trade secret misappropriation, and that Erasca had "improperly compared preclinical data of ERAS-0015 and RMC-6236 in public disclosures."

On this news, Erasca's stock price fell $2.34, or approximately 10.9%, from a closing price of $21.49 on April 24, 2026 to close at $19.15 per share on April 27, 2026.

On April 27, 2026, at approximately 4:17 p.m. EDT, Erasca filed a separate Form 8-K reporting preliminary Phase 1 clinical data for ERAS-0015 and disclosing that one patient that received 24 mg of ERAS-0015 had died approximately a month after starting ERAS-0015, classified as a "Grade 3 TRAE of pneumonitis" that "progressed to Grade 5 after withdrawal of supportive care per patient decision," and further stating that comparisons between ERAS-0015 and other product candidates, including RMC-6236, were "not based on any head-to-head clinical trials" and are "inherently limited and such data may not be directly comparable."

On this news, Erasca's stock price fell $9.25, or more than 45%, from a closing price of $19.15 per share on April 27, 2026 to close at $9.90 per share on April 28, 2026.

The court-appointed lead plaintiff is the investor with the largest financial interest in the relief sought by the class who is adequate and typical of class members who directs and oversees the litigation on behalf of the putative class. Any member of the putative class may move the Court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member. Your ability to share in any recovery is not affected by the decision to serve as a lead plaintiff or not.

Faruqi & Faruqi, LLP also encourages anyone with information regarding Erasca's conduct to contact the firm, including whistleblowers, former employees, shareholders and others.
