Ardent Health Faces Class Action Lawsuit Following Accounting Disclosures and Share Price Collapse

San Francisco, Friday, 9 January 2026.
Investors have initiated a securities class action lawsuit against Ardent Health, Inc. (NYSE: ARDT) after the company’s stock value plummeted approximately 33% in November 2025. Filed on January 8, 2026, the complaint alleges that Ardent Health misled shareholders regarding the collectability of its accounts receivable and the adequacy of its professional liability reserves. Specifically, the lawsuit claims the healthcare operator relied on a “180-day cliff” method rather than detailed historical reviews to reserve accounts, leading to a sudden $43 million revenue reduction and a $54 million increase in liability reserves in Q3 2025. This accounting shift, coupled with a significant cut to the company’s 2025 EBITDA guidance, has raised serious concerns about financial governance. Investors who purchased securities between July 18, 2024, and November 12, 2025, have until March 9, 2026, to join the litigation as lead plaintiffs.
