The latest data point for NET's Return on Sales (ROS) in Q4'25 shows a modest decline to -1.24%, marking a reversal from the brief positive territory achieved in the prior quarter. This value indicates ongoing challenges in profitability, though it remains an improvement over deeper losses seen earlier in the fiscal year. Over the period from Q2'23 to Q4'25, NET's ROS has exhibited a volatile yet gradually improving trend, starting from a low of -29.65% in Q2'23 and fluctuating through negative values such as -8.50% in Q2'25, before reaching a peak of 0.85% in Q3'25—the only profitable quarter in the series. Significant inflection points include a sharp recovery from Q1'24's -8.50% to -3.17% in Q2'24, followed by steady narrowing of losses until the Q3'25 uptick, but the subsequent drop in Q4'25 highlights persistent margin pressures amid the area chart's depiction of uneven growth. No data is available for Q1'26, limiting forward visibility.
