The latest data point for ACHR's operating ROA metrics in Q1'26 shows ROE at -10.47%, ROA at -9.37%, and ROIC at -11.44%, indicating persistent negative profitability with ROA remaining the least severe among the three indicators. Over the period from Q2'23 to Q1'26, all metrics exhibit a volatile yet improving trend from deeply negative values—such as ROE at -66.63%, ROA at -38.23%, and ROIC at -54.80% in Q2'23—to shallower losses, with notable inflection points including a sharp recovery in Q3'23 followed by stabilization around -10% to -20% from Q4'24 onward; this suggests gradual enhancements in asset utilization and capital efficiency despite ongoing operational challenges.
