As a private company with substantial financial backing, we will be able to better manage our business for the long-term in order to serve the best interests of our customers, employees, joint venture partners and other stakeholders.”

“We are excited to acquire EnergySolutions, one of the leading global environmental and nuclear services companies,” said Tyler Reeder, a Partner at ECP. “The Company employs an exceptionally talented workforce experienced in providing critical services to commercial customers and governmental agencies with a strong track record of environmental stewardship. We look forward to investing capital in support of management’s strategic vision to continue to expand the Company’s business both in North America and internationally. In particular, we see a tremendous opportunity for the Company to grow its decommissioning and disposal businesses in the United States, through strategic partnerships with large engineering and construction firms, expanding its services business with governmental agencies, and the rebidding of Magnox and other opportunities in Europe.”

ECP plans to operate EnergySolutions as a standalone business operation with the current management team remaining in place.
