The latest data point for CB's ROS in Q4'25 stands at 26.6%, reflecting a robust quarterly performance and marking one of the highest levels in the observed period. Over the timeframe from Q2'23 to Q4'25, ROS has exhibited an overall upward trend with intermittent fluctuations, starting at 19.9% and peaking at 26.6% in the most recent quarter, driven by notable recoveries such as the sharp rise from 13.7% in Q1'25 to 26.1% in Q2'25. Significant declines occurred in Q3'23 (18.9%) and Q1'25 (13.7%), indicating periodic volatility, while the area chart highlights sustained growth in later periods, with Q4'24 and Q4'25 both exceeding 22.8%. This pattern suggests improving operational efficiency for CB, though analysts should monitor for potential reversals in upcoming quarters like Q1'26, where no data is available.
