Is Eaton a US-based company?

Yes, Eaton is a US-based company in terms of its operational headquarters and historical origins, though its legal domicile is in Ireland for tax purposes. Eaton Corporation was founded in 1911 by Joseph Eaton in New Jersey as a manufacturer of truck axles, and for most of its history it was headquartered in Cleveland, Ohio. Today, its global operational headquarters remains in Beachwood, Ohio, near Cleveland, where many of its senior executives are based and where it has major facilities. However, in 2012 after acquiring Cooper Industries, Eaton reincorporated in Dublin, Ireland, as Eaton Corporation plc, which is a common practice for US multinationals for tax reasons. Despite this legal domicile, Eaton is still considered an American company by most business definitions: it is listed on the New York Stock Exchange under the ticker ETN, it is part of the S&P 500, it has over 40,000 employees in the United States, and its largest markets are in the US. It operates as an American multinational with Irish legal incorporation. So while its official legal headquarters is in Dublin, Ireland, its cultural, operational, and historical identity is American, and it is generally described as a US-based company with Irish domicile.
