In May 2026, Thomas Siebel returned as CEO, signaling a founder-led turnaround, and Cummins Inc. was found liable for misappropriation of C3 AI trade secrets. In June 2026, the company reported preliminary Q4 2026 revenue of $51.6 million and a non-GAAP operating loss of $(54.4) million, with full-year 2026 revenue declining 36% year-over-year, leading to a 26% global workforce reduction and a 22% stock plunge due to disappointing Q4 guidance; however, C3 AI and Shell expanded their collaboration. In August 2026, C3 AI was named a Leader in The Forrester Wave™: AI Platforms, Q3 2026. In September 2026, Q1 FY2027 revenue was $52.4 million (down 25.5% YoY), but bookings increased 73% quarter-over-quarter, non-GAAP net loss reduced, and free cash flow was positive; later that month, shares climbed as part of a broader rebound in enterprise software stocks, driven by renewed attention on the founder-led turnaround and improving bookings. In October 2026, C3.ai stock jumped as technology equities rebounded from a sell-off. Overall, the stock decreased 40.50% over the last 12 months and -15.50% year-to-date, but increased 8.62% in the past month and 28.25% over the last three months.
