History

ERM Limited was formed in 1987, through the merger of two companies: the UK-based consultancy firm ERL, which was founded in 1971; and the USA-based consultancy firm ERM, which was founded in 1977.^[2] The company has since grown through various acquisitions. OMERS and AIMCo purchased a majority stake in ERM from Charterhouse Capital Partners in 2015.^[7] In 2021 the majority stake in the company was purchased from OMERS and AIMCo by American global investment company KKR, valuing the company at around $2.7 billion including debt.^[7] A minority stake continues to be held by ERM partners.

In January 2022, ERM announced the appointment of Tom Reichert as CEO of ERM Group, effective 1 February 2022.^[8]
