The sale is the last part of ABB's measures to trim its portfolio of companies which saw it sell its power transmission unit Dodge and spin off its turbocharging business Accelleron to shareholders.

ABB said it expects to make a small non-operational book gain from the sale of the United-States-based Power Conversion business, which provides products for telecoms, data centres and general industry.

Chief Executive Bjorn Rosengren said he was "delighted" with the deal which completed divisional portfolio divestments announced by ABB at the end of 2020.

Power Conversion was acquired by ABB as part of the GE Industrial Solutions acquisition in 2018 and was not core to ABB, the company said.

The division is based in Plano, Texas, and employs roughly 1,500 employees worldwide. It generated revenues of approximately $440 million and income from operations of approximately $50 million in 2022.
