Steris

Steris was founded in August 1985 in Ohio, under the name "Innovative Medical Technologies".

In 2012, Steris acquired US Endoscopy for $270 million. Steris also acquired Spectrum Surgical Instruments Corp. and Total Repair Express for $110 million combined.

On April 1, 2014, Steris announced its acquisition of Integrated Medical Systems International Inc. for ~$175 million, although it would only cost the company ~$140 million after tax benefits. Shortly after, Steris also acquired Chesterfield, Missouri-based Life Systems.

In October 2014, Steris executed a tax inversion from the United States to the United Kingdom, via an offer made to acquire UK-based Synergy Health for $1.9 billion. The tax inversion was notable as it was the first US inversion post the new rules introduced by the Obama administration in 2014 to curb US corporations moving their "legal domicile" to reduce their exposure to US corporate taxation.

On June 24, 2015, Steris announced the acquisitions of General Econopak for $175 million and Black Diamond Video for $51 million.

Steris filed accounts which showed global revenues of over US$2.6 billion in 2018, of which US$1.8 billion (or 70 percent) came from the US healthcare system; and employed ~12,000 people.

In November 2018, Steris announced that it would further re-domicile its legal headquarters from the United Kingdom to Ireland; Steris had reduced its corporate tax rate from 31.3 percent to 20 percent as a result of its 2014 tax inversion to the United Kingdom, however, it believed a further reduction could be achieved by moving to Ireland.

In April 2020, Steris received emergency use authorization from the FDA for a N95 mask sterilization system to help address the shortage of personal protective equipment during the 2019-20 coronavirus pandemic.
