“Develops AI-based digital finance platform OneStream, Inc. (NASDAQ:OS) shares fell in the quarter after issuing a softer third quarter billings outlook. Management attributed the consensus expected slowdown to lumpier on-premise deal timing, U.S. federal budget uncertainty, and accelerated subscription conversions.
