C3.ai’s bleak early results have shaken Wall Street. Will September’s quarterly earnings report hint at recovery or deepen investor doubts?

C3.ai was plunging as it said quarterly revenue would fall way below expectations. There are further problems ahead.

C3.ai reported expected revenue of $70.2 million to $70.4 million, down 19% year-over-year from $87.2 million in the year-ago quarter. This was well below the company's own guidance midpoint of $104.5 million.
