History

Our History In Ireland

We were once a small company with big ideas. The only thing that's changed is our size. Honoured by the support of the Limerick and Dublin communities, we are continuing to expand our Irish operations.

Regeneron’s history spans over 35 years of a relentless focus to invent, develop and commercialize life-transforming medicines for people with serious diseases.
