Following the acquisition, ISS will continue to operate independently, and the current leadership team will remain in place.
The firm has more than 1,000 employees across 19 offices, globally, providing environmental, social and governance (ESG) solutions including research, data and analytics, distribution and proxy voting services.
Gary Retelny, ISS president and CEO, said: “ISS has the right partner in Genstar to remain sharply focused on our long-standing commitment to provide market-leading expertise, innovation, and service in the area of global corporate governance.”
He added: “We thank Vestar Capital Partners for their commitment to ISS and its clients around the globe over the past three years. It has been a tremendously successful partnership.”
Tony Salewski, capital managing director at Genstar, commented: “While maintaining its status as the premier governance provider, ISS has expanded significantly over the past three years, exhibiting a deep commitment to its clients by building a robust infrastructure and continuing to develop a world-class suite of ESG solutions.”
He added: “We are excited to back Gary and his team in building on this progress through both organic and acquisition growth initiatives globally.”
