Private equity firm Genstar Capital is selling some of its stake in the RIA Mercer Advisors to another private equity shop, Mercer says.

Oak Hill Capital, a 33-year-old private equity firm with around $15 billion of initial capital commitments and co-investments since inception, is acquiring a stake in Mercer Advisors from Genstar, which took a majority stake in Mercer in 2015, and private equity outfit Lovell Minnick Partners, according to a press release from Mercer.

The companies didn’t disclose the terms of the deal nor the size of the stake, but Genstar “will be staying on as an investor and partner,” Dave Welling, Mercer Advisors’ CEO, says in the press release.

Reports first emerged this summer that Genstar could be looking to sell some or all of its stake.

Since Genstar and Lovell Minnick acquired the majority stake four years ago, Mercer Advisors has almost tripled its assets under management, from $5.8 billion to $16.5 billion, in large part through 23 acquisitions, Mercer Advisors says.

Earlier this month, Mercer Advisors added an RIA in New Mexico overseeing around $100 million, and in August it added a Connecticut RIA managing $300 million.

Based in Denver, Mercer Advisors now has more than 370 employees working out of 44 offices around the country, according to the press release.
