HOUSTON & TORONTO–(BUSINESS WIRE)–Resource Environmental Solutions, LLC (“RES” or “the company”), the nation’s largest ecological restoration company, today announced that Onex Partners V, Onex Corporation’s (“Onex”)(TSX:ONEX) $7.2 billion fund, has agreed to make a significant investment in RES, together with funds affiliated with the company’s existing investor, KKR.

Today, RES is the environmental employer of choice. With the backing of Onex Partners and KKR, we will continue to invest in talent and capabilities, and grow into new markets and new communities. Our access to additional investment capital will also help us to continue with product line expansion into coastal resiliency, large scale water quality projects, new mitigation banks, and carbon solutions,” Whitley continued.

Amir Motamedi, a Managing Director of Onex Partners, said: “RES is the nation’s leading provider of nature-based solutions and green infrastructure thanks to the contributions of every team member at the company. With its strong culture and can-do spirit, we’re confident RES will continue its growth trajectory both organically and through acquisitions. We are delighted to be partnered with Darrell, the entire RES team and KKR during this next chapter.”

Robert Antablin and Ken Mehlman, Co-Heads of KKR Global Impact, added: “We are thrilled to continue our relationship with RES and support them, alongside Onex Partners, on their mission to help communities navigate the impacts of climate change. While we have made great progress since KKR’s initial investment in helping to establish RES as an industry leader while growing the company’s operations, capabilities and team, we are looking forward to even more growth ahead.”

Elliott Bouillion, Founder and Executive Chairman, concluded, “I am thrilled to see RES continue its journey and mission to restore a resilient earth for our modern world. I believe that Onex Partners and KKR will be formidable partners and dedicated stewards of our business during the next phase of ownership. I look forward to working closely with Onex Partners, KKR, Darrell and the rest of the RES management team as we aim to take RES to the next level and drive even more growth and transformation in the years ahead.”
