UnitedHealth Group is facing a class action lawsuit from investors, who allege the company misled them after the December killing of top executive Brian Thompson.

The company never told investors how it planned to shift its strategy following public backlash and increased government scrutiny, the new lawsuit alleges.

UnitedHealth Group was sued on Wednesday for allegedly concealing how backlash from the killing of a top executive was damaging its business, causing its stock to nosedive after the insurer lowered its 2025 outlook.
