The latest data point for ACHR's ROS in Q4'25 shows a value of -629.67%, indicating substantial operational losses for the period. The chart covers quarterly ROS from Q1'23 to Q4'25, with no data available from Q1'23 through Q3'25, resulting in no discernible trends or patterns during that span; the sole reported figure in Q4'25 highlights a sharp negative performance, but without prior values, overall growth, decline, or stability cannot be assessed.
