Pfizer Inc.

Pfizer Inc. is an American multinational pharmaceutical and biotechnology corporation headquartered at The Spiral in Manhattan, New York City. Founded in 1849 as Charles Pfizer & Company, the company's core business revolves around the discovery, development, manufacture, marketing, sales, and distribution of biopharmaceutical products globally. Its mission is centered on delivering "Breakthroughs that change patients' lives.".

The company develops and produces medications and vaccines across a broad range of therapeutic areas, including immunology, oncology, cardiology, endocrinology, neurology, rare diseases, internal medicine, inflammation, and anti-infectives. Key products by sales have included Eliquis (apixaban), Prevnar (pneumococcal conjugate vaccine), Paxlovid (Nirmatrelvir/ritonavir), Vyndaqel (tafamidis), Comirnaty (the Pfizer–BioNTech COVID-19 vaccine), and Ibrance (palbociclib). Pfizer's portfolio also historically includes well-known products like Lipitor, Viagra, and Zoloft.

Under the leadership of Chairman and CEO Albert Bourla, Pfizer is navigating a strategic shift, focusing on core therapeutic areas such as oncology, vaccines, rare diseases, and specialty medicines, moving beyond the significant, but now declining, revenue from its COVID-19 products. Recent notable activities include the $43 billion acquisition of Seagen in December 2023, which significantly bolstered its oncology portfolio, and the acquisition of Biohaven Pharma in October 2022. The company faces challenges from upcoming patent expirations for several key products and is implementing cost-cutting initiatives while advancing a robust pipeline of therapies, with 32 therapies currently in Phase 3 development.
