As of Q4'25, ASML's P/S Ratio has surged to 41.97, marking a significant spike compared to previous quarters. This latest data point represents a dramatic increase from Q3'25, where the ratio stood at 10.44. From Q1'23 to Q3'25, the P/S Ratio generally fluctuated between 7.3 and 13.25, with periods of moderate volatility and no extreme outliers. However, the sharp rise in Q4'25 breaks this pattern, indicating a sudden and substantial change in valuation relative to sales. This anomaly suggests either a rapid increase in market capitalization or a decrease in sales, and warrants further investigation into the underlying drivers during this period.
