C3.ai said in an 8-K filed May 12, 2026 that its board had unanimously appointed founder Thomas M. Siebel chief executive officer and chairman, effective May 8, 2026. An 8-K is the report a US-listed company files when a material event occurs; this one covered item 5.02, changes among directors and senior officers, and item 2.02, results of operations. Stephen Ehikian, 44, who had been chief executive since September 2025, was to serve as president from the same day. Siebel, 73, had been executive chairman since September 2025, and before that was chief executive from July 2011. In the press release attached to the 8-K, Siebel said he looked forward to working with Ehikian toward consistent free cash flow, non-GAAP profitability and a return to significant top-line growth.1^,2^,3^,4^,5^,6^,7

The release also gave preliminary results for the fiscal fourth quarter and the full fiscal year ended Apr 30, 2026, which the company said were unaudited estimates. Revenue for the quarter was $51.6 million, inside the company's guidance range of $48.0 to $52.0 million, and revenue for the year was $250.3 million, inside its guidance range of $246.7 to $250.7 million. The loss from operations under US accounting rules (GAAP) was $121.2 million for the quarter, against $89.0 million a year earlier, and $498.5 million for the year, against $324.4 million the year before. The company's own non-GAAP loss from operations, which leaves out restructuring expenses, stock-based compensation charges and the payroll tax on them, was $54.4 million for the quarter, against $31.2 million a year earlier, and $217.8 million for the year, against $88.1 million. The company said the quarter's non-GAAP figure was better than its own guidance range. In that quarter the adjustments were stock-based compensation of $54.1 million, payroll tax on it of $1.9 million and restructuring charges of $10.8 million. The company ended the year with $575.4 million in cash, cash equivalents and investments.8^,9^,10^,11^,12^,13^,14^,15^,16^,17

C3.ai said it signed 28 agreements in the quarter, including nine new initial production deployments and seven conversions of such deployments, and said bookings were lower than expected. The release described a restructuring plan designed to deliver approximately $135 million in annualized non-GAAP cost savings and said its workforce-related actions were substantially complete. An earlier 8-K, filed Feb 25, 2026, had reported a restructuring plan that the board approved on Feb 24, 2026, including a 26% reduction in the global workforce.18^,19^,20^,21^,22

C3.ai said completed results would follow on Jun 3, 2026, and an 8-K filed that day reported a press release announcing them. The company's results for the year to Apr 30, 2026 later showed revenue of $250.27 million, against $389.06 million the year before. For the quarter from May 1 to Jul 31, 2026, revenue was $52.38 million, against $70.26 million a year earlier, and the loss from operations was $98.27 million, against $124.82 million.9^,23^,24^,25^,26^,27^,28^,29^,30
