About
Pfizer is one of the world's largest biopharmaceutical companies, founded in 1849 by cousins Charles Pfizer and Charles Erhart in Brooklyn, New York, and now headquartered in New York City. The company trades on NYSE (PFE) and reported $63.6 billion in total revenues for FY2024, normalizing from pandemic highs of $100 billion-plus in 2021-2022 driven by Comirnaty COVID-19 vaccine revenues with BioNTech and Paxlovid COVID antiviral sales. CEO Albert Bourla has led a strategic pivot to reset the company's long-term growth profile, anchored by the landmark $43 billion acquisition of Seagen in December 2023, adding a world-class antibody-drug conjugate (ADC) oncology pipeline including Padcev, Tukysa, Adcetris, and Tivdak.
