The proposed Connecticut securities class action alleges GeneDx failed to disclose margin pressure, revenue misses, reduced guidance and a Fabric Genomics impairment before shares fell 49.2% on May 4, 2026.
Kahn Swick & Foti said investors who purchased or otherwise acquired GeneDx Holdings Corp. shares between April 16, 2025 and May 4, 2026 have until Aug. 3, 2026 to seek appointment as lead plaintiff in a proposed securities class action pending in the United States District Court for the District of Connecticut. The case, Basma v. GeneDx Holdings Corp., alleges GeneDx and certain executives failed to disclose material information in violation of federal securities laws. According to the complaint, GeneDx disclosed on May 4, 2026 that adjusted gross margin fell to 69% from 74%, it missed revenue estimates for both its exome and genome lines, it cut full-year revenue guidance to $475 million to $490 million from $540 million to $550 million, and it recorded a $31.2 million impairment loss tied to Fabric Genomics. KSF said GeneDx shares fell $33.42, or 49.2%, on that news.
