As of Q4'25, ACHR's latest Operating ROA stands at -7.7%, with ROE at -8.6% and ROIC at -9.9%. These figures, while still negative, represent the most recent data points in the time series covering Q1'23 through Q4'25. Over the observed period, all three profitability ratios—ROA, ROE, and ROIC—have shown a general trend of improvement, moving from deeper negative values in 2023 toward less negative levels by the end of 2025. Notably, the most significant improvements occur between 2024 and 2025, with each metric narrowing its losses, suggesting operational performance is stabilizing. Despite remaining below zero, the consistent upward trajectory indicates ACHR is gradually reducing its operational inefficiencies.
