- Severe Market Reaction: GRAIL, Inc. lost over $2.2 billion in market capitalization following the NHS-Galleri trial readout, with shares plummeting more than 50% the next day, reflecting strong investor disappointment and distrust in the company's future prospects.
- Legal Action Initiated: In response to the trial's failure to meet its primary endpoint, Hagens Berman has launched a securities class action lawsuit representing investors who purchased GRAIL stock between May 13, 2025, and February 19, 2026, alleging violations of federal securities laws by the company and its executives.
- Disclosure Controversy: The lawsuit claims that GRAIL misled investors regarding the trial's design and expected outcomes, asserting that the three-year follow-up was sufficient to significantly reduce late-stage cancer diagnoses, while internal information suggested this timeframe might be inadequate to support trial success.
- Ongoing Investigation: Hagens Berman is investigating when GRAIL's management became aware of the need for a longer follow-up period and encourages individuals with knowledge to come forward to assist in holding the company and its executives accountable.

About GRAL
Grail, Inc. is a healthcare company focused on saving lives and shifting the paradigm in early cancer detection. The Company is focused on alleviating the global burden of cancer by using sequencing, population-scale clinical studies, and machine learning, software, and automation to detect and identify multiple deadly cancer types in earlier stages. Its targeted methylation-based platform can support the continuum of care for screening and precision oncology, including multi-cancer early detection in symptomatic patients, risk stratification, minimal residual disease detection, biomarker subtyping, treatment and recurrence monitoring. Its multi-cancer early detection test, the Galleri test, is a commercially available screening test for early detection of multiple types of cancer. The Galleri test can be used to screen for cancer before a person becomes symptomatic, when cancer may be more easily treated and potentially curable. The Galleri test can indicate the origin of the cancer.
