PFIZER INC

Our operations are conducted globally, and we supply our medicines and vaccines to approximately 200 countries and territories. Emerging markets are an important component of our strategy for global leadership, and our commercial structure recognizes that the demographics and rising economic power of the fastest-growing emerging markets are becoming more closely aligned with the profile found within developed markets. Urbanization and the rise of the middle class in emerging markets provide potential growth opportunities for our products.

Revenues from operations outside the U.S. of $31.4 billion accounted for 54% of Total revenues in 2023. Revenues exceeded $500 million in each of 14, 24 and 21 countries outside the U.S. in 2023, 2022 and 2021, respectively. The decrease in the number of countries exceeding $500 million in revenues from 2022 to 2023 was primarily driven by decreases in revenues related to Comirnaty and Paxlovid. As a percentage of Total revenues, our largest country outside the U.S. was Japan in 2023. For a geographic breakdown of Total revenues, see the Total Revenues by Geography section within MD&A and Note 17B.

Our international operations are subject to risks inherent in carrying on business in other countries. See the Item 1A. Risk Factors—Global Operations and Item 1. Business—Government Regulation and Price Constraints sections.
