Aggreko History, Ownership, and Financial Performance
Aggreko was founded in 1962 by Luc Chatelain in Glasgow, Scotland, and the company was originally focused on renting portable cooling and heating equipment. The company expanded into power generation during the 1990s and was listed on the London Stock Exchange in 1997. In 2021, Aggreko was acquired by private equity firm Melrose Industries in a deal valued at approximately 3.8 billion pounds, and the company was delisted from the London Stock Exchange, according to financial news coverage by Forbes.
