The latest data point for ZS's Return on Sales (ROS) in Q2'26 stands at -2.09%, indicating a slight deterioration from the near-breakeven performance of 0.02% in the prior quarter (Q4'25). This negative figure reflects ongoing challenges in achieving profitability, with the metric remaining below zero despite intermittent improvements. Over the period from Q3'23 to Q2'26, ZS's ROS has shown a volatile trajectory, starting at -9.07% and gradually narrowing losses to -0.20% by Q1'25, before fluctuating into positive territory with a peak of 4.27% in Q3'24. Subsequent quarters reverted to minor losses, highlighting inconsistent operational efficiency amid potential growth investments; overall, the trend suggests slow progress toward sustained profitability, with an average ROS hovering around -1.5% across the 12 quarters.
