Black-Owned Investment Firm Buys Industrial Services Provider As Energy Demand Soars

Ariel Alternatives has acquired Groome Industrial Service Group, a provider of industrial cleaning and maintenance solutions. JPMorgan Chase & Co. joined the deal with a minority stake through its asset management division.
Founded by business leader Mellody Hobson, Ariel Alternatives is the private equity arm of Ariel Investments, one of the largest Black-owned money managers in the US. The acquisition will help Groome, which employs more than 900 people across more than 20 US sites, expand its market share by tapping into the firm’s ties in the energy and utilities sector.

The deal comes amid surging energy demand, fueled by the rise of AI, the rapid buildout of data centers, and an aging US power generation fleet. Groome is thought to be well-positioned to capitalize on these trends, providing outsourced, specialized maintenance and cleaning solutions to a growing industry.
“At Ariel Alternatives, our mission is to support companies and leadership teams with a bold vision for growth and the talent to realize it. In Jeff and the Groome team, we have found exactly that,” Les Brun, Co-Founder, Chairman, and Chief Executive Officer of Ariel Alternatives, said. “We are energized by the partnership and confident in what we will accomplish together.”
