As of 2024, its largest institutional shareholders include The Vanguard Group (8.3% ownership), BlackRock (7.2%), and State Street Corporation (4.1%). The company was founded in 1849 by Charles Pfizer and Charles Erhart and has been publicly traded on the New York Stock Exchange since 1942.

Key Facts

Overview

Pfizer Inc. represents one of the world's largest and most influential pharmaceutical corporations, tracing its origins to 1849 when German immigrants Charles Pfizer and Charles Erhart established a fine-chemicals business in Brooklyn, New York. The company initially specialized in producing santonin (an anti-parasitic), camphor, and iodine before expanding into pharmaceutical manufacturing. Throughout its 175-year history, Pfizer has evolved from a small chemical importer to a global healthcare giant through strategic acquisitions, innovative drug development, and international expansion.

As a publicly traded entity, Pfizer operates under a shareholder ownership model where institutional investors, mutual funds, and individual shareholders collectively own the company. The pharmaceutical giant maintains headquarters in New York City and employs approximately 83,000 people worldwide as of 2024. Pfizer's ownership structure reflects modern corporate governance with diversified ownership across thousands of shareholders rather than concentrated family or private equity control.

How It Works

Pfizer's ownership and governance structure operates through a sophisticated system of public markets, institutional investment, and corporate oversight mechanisms.
