Endo International plc is a generics and specialty branded pharmaceutical company. It was created as a result of a management buyout from DuPont Merck in 1997 led by Carol Ammon.[1]


In 2009, Endo bought Indevus Pharmaceuticals to diversify into endocrinology and oncology.[2] The company entered the male hypogonadism market later in 2010 with Fortesta 2% gel.[2]

In November 2013, Endo agreed to purchase Paladin Labs Inc for about $1.6 billion to gain access to the Canadian market as well as expand into emerging markets.[3][4]

In October 2014, Endo said it would buy Auxilium Pharmaceuticals for $2.6 billion.[5]

In 2015, Endo acquired the specialty generics and sterile injectables company Par Pharmaceutical for $8.05 billion.[6]

Acquisition attempts[edit]

In early 2014, Endo sought to acquire NuPathe, a speciality pharmaceutical developer, for $105 million.[7] However, Teva prevailed in this acquisition with a substantially higher bid.[8]


Endo is one of the companies named in lawsuits by the states of Ohio[9], Missouri and Mississippi[10] as responsible for the US opioid epidemic. Its 10-K statement indicates that a majority of the company's US revenue in 2016 was derived from the sale of prescription pain killers, predominantly opioids.[11]
