Endo International plc is an American Irish-domiciled generics and specialty branded pharmaceutical company that generated over 93% of its 2017 sales from the U.S. healthcare system. While Endo's management, operations, and customers are almost exclusively U.S.–based, in 2013 Endo executed a corporate tax inversion to Ireland to avoid U.S. corporate taxes on their U.S. drug sales, and to avail of Ireland's corporate tax system.[1][2][3]
History
In 1920, Intravenous Products of America was incorporated as a privately owned pharmaceutical business operating in New York. By 1935 it had changed its name to Endo Products.[4] The product line focused on medication for the treatment of pain (e.g. Percodan), a focus which continued during its acquisition by DuPont in 1969 (e.g. Percocet).[5]
