As of Q4'25, NBIS reported a ROS (Return on Sales) of -0.92%, marking a continued negative trend from the previous quarter and indicating ongoing profitability challenges. The most recent data point reflects a significant deterioration compared to earlier quarters, with the ROS remaining below zero. From Q1'23 to Q4'25, the ROS exhibited high volatility, initially improving from 4.54% in Q1'23 to a peak of 11.57% in Q2'23 before declining sharply and turning negative in Q2'24 at -377.11%. The metric briefly rebounded to 576.46% in Q2'25, but quickly fell back into negative territory by Q3'25 and Q4'25. This erratic pattern suggests significant operational instability and inconsistent profitability over the observed period.
