As of Q4'25, ABBV's latest P/S Ratio stands at 24.48, representing a dramatic increase from the previous quarter's value of 6.40. This sharp jump marks a significant deviation from the recent trend and is the highest value observed in the period covered. From Q1'23 to Q3'25, ABBV's P/S Ratio generally fluctuated between 4.5 and 6.4, showing moderate growth with some quarter-to-quarter volatility. However, the sudden spike in Q4'25 indicates a notable inflection point, suggesting either a substantial increase in market capitalization or a sharp decline in revenue. This abrupt change warrants further investigation, as it breaks the relatively stable pattern seen throughout the previous quarters.
