C3 AI (AI) Nosedives as Preliminary Results 'Completely Unacceptable'

We recently published 10 Stocks Collapse Overnight. C3.ai, Inc. (NYSE:AI) is one of the best-performing stocks on Monday.

C3.ai fell for a fourth straight day on Monday, slashing 25.58 percent to close at $16.47 apiece after its chief executive called the preliminary results of its first quarter of fiscal year 2026 performance “completely unacceptable.”

According to C3.ai, Inc. (NYSE:AI), it was targeting to report total revenues of $70.2 million to $70.4 million, and GAAP operational loss of $124.7 million to $124.9 million. Non-GAAP loss from operations was targeted at $57.7 million to $57.9 million.

Commenting on the results, C3.ai, Inc. (NYSE:AI) CEO Tom Siebel said the sales figures were “completely unacceptable,” and pointed to disruptions from a recent leadership reorganization, and his health contributing to the company’s poor performance.

Last month, C3.ai, Inc. (NYSE:AI) announced that it was searching for a new CEO after Siebel tendered his resignation due to health reasons, effective upon a successor assuming his post.

“After being diagnosed with an autoimmune disease in early 2025, I have experienced significant visual impairment,” he was quoted as saying last month.

“For C3 AI to reach its full potential—which I believe is spectacular—the board and I have initiated a search for a new CEO who can take the company to the next level of growth and success. I will remain fully engaged as Chief Executive Officer of C3.ai until such time as the C3.ai board appoints my successor, after which I will continue in the role of Executive Chairman, focusing on strategy, product innovation, strategic partner and customer relationships,” he noted.
