C3.ai: Navigating Consecutive Quarters of Revenue Contraction

C3.ai (NYSE:AI) derives its core revenue from delivering a comprehensive suite of enterprise software applications powered by artificial intelligence, along with a centralized development environment designed to help global organizations build and operate custom digital systems.

During a period marked by corporate restructuring — including a significant workforce reduction — resolution of a securities class action lawsuit, and the acquisition of new enterprise agreements, the company reported an operating margin of -188% for the quarter ended July 31, 2026.

UiPath: Maintaining Steady Revenue and Consistent Year-Over-Year Growth

Foolish Take

While both C3.ai and UiPath operate within the artificial intelligence sector, UiPath generates far greater revenue and is enjoying a trend of consistent year-over-year sales growth, whereas C3.ai faces a year-over-year decline. This divergence highlights the broader market appeal of UiPath’s AI solutions compared to C3.ai’s offerings.

However, there are additional factors behind C3.ai’s declining sales. The company’s founder and CEO, Thomas Siebel, resigned from the role in 2025 due to health issues. Under his leadership, C3.ai performed strongly, as reflected in its substantially higher quarterly revenue totals throughout 2024 and into late 2025. He returned to the CEO position in June, but during his absence, the company’s business deteriorated significantly.

Siebel’s return appears to be having a positive impact. In C3.ai’s fiscal first quarter ended July 31, customer bookings increased 73% quarter over quarter, which bodes well for future revenue growth.

Meanwhile, UiPath’s sales trajectory appears to be decelerating. The company’s revenue of $410.3 million in its fiscal second quarter ended July 31 represented approximately a 13% year-over-year increase. However, management projects third-quarter sales to fall in the range of $440 million to $445 million — roughly 8% year-over-year growth — marking a notable slowdown from the second quarter.
