GRAL TUESDAY DEADLINE: GRAIL, Inc. Investors with Substantial Losses Have Opportunity to Lead Shareholder Class Action Lawsuit

The law firm of Robbins Geller Rudman & Dowd LLP announces that purchasers or acquirers of GRAIL, Inc. (NASDAQ: GRAL) common stock between May 13, 2025 and February 19, 2026, both dates inclusive (the "Class Period"), have until this Tuesday, August 4, 2026 to seek appointment as lead plaintiff of the Grail class action lawsuit. Captioned Robbins v. Grail, Inc. , No. 26-cv-05428 (N.D. Cal.), the Grail class action lawsuit charges Grail as well as certain of Grail's current and former executive officers with violations of the Securities Exchange Act of 1934.

Grail is a commercial-stage healthcare company that provides multi-cancer early detection testing and services. It offers Galleri, a cancer screening test for asymptomatic individuals over 50 years of age; and a diagnostic aid for cancer tests to accelerate diagnostic resolution for patients with clinical suspicion of cancer.

According to the complaint, one of Grail's Galleri trials was the "NHS-Galleri trial," the primary objective of which was "to show a reduction in late-stage (III-IV) cancers in people who received the Galleri test compared with those who did not." The Grail class action lawsuit alleges that defendants throughout the Class Period made false and/or misleading statements and/or failed to disclose that: (i) defendants created the false impression that they possessed reliable information pertaining to the probability of achieving the primary endpoint of a statistically significant reduction in Stage III-IV cancers in Grail's NHS-Galleri trial, while also concealing material adverse facts which reduced the possibility of such an outcome; (ii) in truth, Grail's optimism in achieving the primary endpoint of its NHS-Galleri study fell short of reality; and (iii) the confidence management provided in light of the "Positive Top-Line Results" from the trial's first screening round and the Pathfinder studies was misplaced and ignored potential trendlines in unreleased topline data and other information learned since the inception of the study that suggested three years would be less sufficient than previously thought to demonstrate the achievability of the primary endpoint.

The Grail class action lawsuit further alleges that on February 19, 2026, Grail announced that "primary endpoint of statistically significant Stage III-IV reduction was not observed" in the NHS-Galleri Trial. Grail allegedly attributed this shortcoming, in part, on "probably need[ing] a longer follow-up time to be able to [compare the study arms] adequately." On this news, the price of Grail stock fell more than 50%, according to the complaint.
