Regeneron’s co-Founders reflect on 2023 accomplishments.

JUMP TO OUR MISSION IN MOTION

Forging Our Future Through Scientific Innovation

2023 was another remarkable year of growth through scientific excellence. We brought two new medicines to people in need, advanced numerous possible first- and best-in-class opportunities in our pipeline and steadily grew our business.

We welcomed thousands of new colleagues to our offices around the globe and continued to work together with a science-first mindset to bring vital medicines to people with serious diseases.

Dear Fellow Shareholders...

Regeneron, at its core, is a company dedicated to the discovery and development of innovative medicines manufactured and commercialized to the highest standards. This approach has established us as a world-class biotechnology company, making a true difference in people’s lives. Our ability to create game-changing technologies has disrupted the traditional drug discovery, development, and manufacturing processes, and allows us to continue to push the boundaries of science. Our success can be largely attributed to two factors: our talented team’s unwavering dedication to patients and our consistent strategy of investing and reinvesting in the highest quality science, research, and technologies.
