Ares Management Corp. has acquired SLR Consulting, a top environmental, social and governance consultancy, from Charterhouse Capital.

SLR, which is headquartered in Buckinghamshire, UK, has more than 2,300 staffers in more than 100 offices in the US, Canada, Europe, and the Asia Pacific regions.

It focuses on the financial services, energy, mining, infrastructure and manufacturing sectors.

Charterhouse took a majority stake in SLR in 2019. It bankrolled an acquisition drive of 15 companies, including Corporate Citizenship and Vectos.

Neil Penhall, SLR CEO, credits Charterhouse for an ambitious expansion plan that positioned SLR to capitalize on the growing demand for a wide range of ESG and sustainability services.

Stephane Etroy, Ares partner, said, “the heightened focus on sustainability and the secular trends supporting the acceleration of climate transition will continue to provide strong growth opportunities for SLR.”

Ares, an alternative investment firm based in Los Angeles, has $325B in assets under management. It is listed on the New York Stock Exchange.
