As of Q2'25, American Express (AXP) reported an ROE of 8.93%, an ROA of 0.98%, and a notable spike in ROIC to 56.56%. This marks a substantial increase in ROIC compared to previous quarters, while ROE and ROA remain within their historical ranges. From Q1'23 to Q2'25, the chart shows that both ROE and ROA have generally followed a stable to mildly upward trend, with periodic fluctuations but no extreme volatility. ROIC, however, remained relatively low and stable until Q1'25, after which it surged dramatically in Q2'25, indicating a significant change in capital efficiency. This sharp rise in ROIC is a key outlier in the data and warrants further investigation into underlying business or accounting events during this period.
