Amgen IncClass action investigation and potential legal claims from data breach.

Edelson Lechtzin LLP has launched a class action investigation into a data breach at Amgen Inc. that exposed patient protected health information and proprietary company data. Amgen identified unauthorized activity in July 2026 involving data stored in third-party cloud environments, and a forensic investigation confirmed that attackers had exfiltrated sensitive files. On July 29, 2026, Amgen concluded the incident is material due to the volume and potential sensitivity of the compromised information, and it disclosed the breach in a Form 8-K filed with the U.S. Securities and Exchange Commission on July 31, 2026. The law firm is evaluating potential legal claims on behalf of affected individuals, who may face increased risk of medical identity theft and fraud.
