Eaton 

Founded in 1911 by Joseph Eaton, the eponymous company began by selling truck axles in New Jersey. Eaton has since become an industrial powerhouse largely through acquisitions in various end markets. Eaton's portfolio can broadly be divided into two parts: its electrical and industrial businesses. Its electrical portfolio (representing around 70% of company revenue) sells components within data centers, utilities, and commercial and residential buildings, while its industrial business (30% of revenue) sells components within commercial and passenger vehicles and aircraft. Eaton receives favorable tax treatment as a domiciliary of Ireland, but it generates over half of its revenue within the US.
