Kaplan Fox Alerts Investors to a Securities Class Action Against C3.ai, Inc. (AI) - Deadline is October 21, 2025

CLICK HERE TO JOIN THE CASE

If you purchased C3.ai securities during the Class Period and have suffered losses, you may CLICK HERE to contact us. You may also contact Kaplan Fox by emailing pmayer@kaplanfox.com or by calling (646) 315-9003.

DEADLINE REMINDER: If you are a member of the proposed Class, you may move the court no later than October 21, 2025 to serve as a lead plaintiff for the purported class.  If you have losses, we encourage you to contact us to learn more about the lead plaintiff process. You need not seek to become a lead plaintiff in order to share in any possible recovery.

On August 8, 2025, after markets closed, C3.ai issued a press release announcing preliminary financial results for the first quarter of 2026, including total revenue for the quarter of $70.2 million to $70.4 million, significantly below the previous guidance range of $100 million to $109 million.

Later that day, C3.ai issued another press release announcing a restructuring of its sales and services organizations to accelerate growth.  Thomas Siebel, the Chief Executive Officer, stated that “the sales results in Q1 were completely unacceptable,” and attributed the disappointing results to two factors: 1) a disruptive effect of a reorganization with new leadership, and 2) his own health issues that prevented his active involvement in the sales processes.

Following this news, the price of C3.ai stock fell $5.66 per share, or 25.58%, to close at $16.47 per share on August 11, 2025.
