PFIZER INC

We own and lease space globally for sales and marketing, customer service, regulatory compliance, R&D, manufacturing and distribution and corporate enabling functions. In many locations, our business and operations are co-located to achieve synergy and operational efficiencies. Our global headquarters are located in New York City. We continue to advance our global workplace strategy to provide workplaces that enable collaboration and foster innovation. As of December 31, 2023, we had 284 owned and leased properties (including properties acquired in the Seagen acquisition), amounting to approximately 38 million square feet. The recent Seagen acquisition has increased our real estate portfolio by 14 sites totaling 1 million square feet.

As of December 31, 2023, of the 284 properties, PGS had responsibility for 37 plants around the world, which manufacture products for our commercial divisions, including in Belgium, Germany, India, Ireland, Italy, Japan, Singapore and the U.S. The leadership team for PGS is primarily located in New York City. PGS also operates multiple distribution facilities around the world.

In general, we believe that our properties, including the principal properties described above, are well-maintained, adequate and suitable for their current requirements and for our operations in the foreseeable future. See Note 9 for amounts invested in land, buildings and equipment.
