In Q4'25, ABBV's net income reached $1.82B USD, marking a strong recovery from the previous quarter's $186M USD and a substantial 83.5% year-over-year increase, which highlights improved profitability at the end of the fiscal year. Over the period from Q1'23 to Q4'25, net income exhibited high volatility, starting at $239M USD in Q1'23, peaking at $2.02B USD in Q2'23, and experiencing a sharp decline to a loss of -$22M USD in Q4'24 before rebounding to $1.82B USD in Q4'25. Year-over-year changes were mixed, with significant growth of 472.8% in Q1'24 contrasting against declines like -88.1% in Q3'25, indicating inconsistent performance likely influenced by operational or market factors. Overall, the trend shows resilience in the latter half of the period despite earlier fluctuations.
