Overview of Case Allegations
C3.ai operates as an enterprise artificial intelligence software company. The lawsuit claims that the company and its executives misled investors by presenting an overly optimistic revenue outlook and growth projections. These statements allegedly downplayed risks related to CEO Thomas M. Siebel’s health, which significantly impacted the company’s leadership stability and profitability.
On August 8, 2025, C3.ai reported disappointing preliminary results for Q1 of fiscal year 2026 and lowered its full-year revenue guidance. The company cited poor sales driven by organizational changes and CEO health concerns. Following this announcement, the stock price dropped more than 25%, triggering the lawsuit allegations.
