As of the latest data point for Q4'25, VST's Operating ROA metrics show ROE at null, ROA at 6.03%, and ROIC at -21.26%. This marks a significant drop in ROIC compared to previous quarters, while ROA has rebounded to its highest level in the observed period. From Q1'23 to Q4'25, the chart reveals considerable volatility across all three metrics. ROE and ROA experienced negative values in late 2023 and early 2024, followed by sharp recoveries—most notably in Q3'24 for ROE (34.70%) and ROA (4.98%). ROIC, after peaking at 10.33% in Q3'24, declined sharply and turned negative in Q4'25. The overall trend suggests periods of operational instability, with brief recoveries punctuated by significant downturns, especially in the most recent quarter.
