OSK Q3 deep dive: fire truck production headwinds and backlog growth shape outlook
OSK reported Q3 revenue of $2.84B, missing estimates, and lowered full-year guidance. Fire truck production faced headwinds, while access equipment demand remained strong. Backlog grew 10.6% YoY to $15.15B. Management expects fire truck output to increase by 10% in 2027, but at a slower pace than initially targeted.
