The latest data point for FTNT's Return on Sales (ROS) in Q4'25 stands at 34.4%, reflecting a modest quarter-over-quarter decline from 34.8% in Q3'25, yet remaining above the 30% threshold amid ongoing market pressures. Over the period from Q2'23 to Q4'25, ROS has exhibited an overall upward trend, rising from 23.1% to a peak of 41.5% in Q3'24, driven by strong operational efficiencies and revenue growth in cybersecurity segments. However, the metric has shown volatility post-peak, with a notable dip to 32.0% in Q2'25 before stabilizing around 34-35% in the latter quarters, indicating potential margin compression from increased competition or costs; Q1'26 has no data available.
