As of Q4'25 (2025-12-31), ABBV's latest reported operating income reached 5.81B USD, representing a significant year-over-year growth rate of 489.87%. This marks the highest operating income within the period covered, following a notable recovery from the negative operating income of -1.49B USD seen in Q4'24. From Q1'23 to Q4'25, ABBV's operating income exhibited considerable volatility, with several sharp fluctuations and a dramatic dip into negative territory in Q4'24. Despite this setback, the company rebounded strongly in 2025, particularly in Q4'25, which saw both a record high in absolute income and the most pronounced YoY growth. The overall trend suggests periods of instability followed by robust recovery, highlighting both the risks and growth potential in ABBV's operational performance over the observed quarters.
