The latest data point for Pfizer's (PFE) revenue in Q4'25 stands at $17.56B USD, reflecting a modest year-over-year decline of -1.16% compared to the prior year, amid ongoing pressures in the pharmaceutical sector. Over the period from Q1'23 to Q4'25, revenue exhibited a volatile yet recovering trend, starting at a high of $18.28B in Q1'23 before dropping sharply to a low of $12.73B in Q2'23—a 30% decline—driven by post-pandemic market adjustments. From Q2'24 onward, the trajectory improved with consistent growth, peaking at $17.76B in Q4'24 and stabilizing around $16-17B in subsequent quarters, while YoY growth shifted from deep negatives (-54% in Q2'23) to positive territory (up to 33.8% in Q3'24) before moderating to slight declines in late 2025, indicating resilient operational recovery.
