Bernhard Capital-Backed Allied Power Acquires Dominion Engineering

Significantly Expands Technical Service and Engineering Offerings for Nuclear Power Customers

BATON ROUGE, La., Sept. 14, 2023 /PRNewswire/ — Allied Group Holdings, LLC (“Allied” or the “Company”), a full-service provider of power plant services, today announced that it has acquired Dominion Engineering, Inc. (“DEI”), a leading provider of field service equipment, technology, and specialized engineering services to the nuclear power industry. Financial terms of the transaction were not disclosed.

Allied provides a diversified range of services – from routine maintenance to outage services and management, capital construction and specialized support – for power plants across the asset life cycle throughout the U.S. In November 2020, the Company was acquired by Bernhard Capital Partners, an infrastructure and services-focused private equity management firm.

For more than four decades, DEI has provided innovative field service equipment, technology, and expert consulting services that help nuclear utilities and operators improve plant performance and reliability, as well as increase the efficiency of refueling outages, decommissioning and waste management activities. DEI’s products and services have been consistently recognized for exemplary technical contributions to engineering projects throughout the nuclear energy sector from new reactor projects to backend waste management.

The acquisition of DEI builds on Allied’s expansion of its offerings, following the Company’s acquisition of Radiation Safety and Control Services (RSCS), a provider of project management, technical, and laboratory services to the nuclear power industry, the Government, and other companies that use radioactive material, in 2022. DEI’s services complement Allied’s existing offerings while simultaneously unlocking new opportunities for the Company to capitalize on the growing market for nuclear energy, as decarbonization goals, public investment initiatives in nuclear energy, and aging nuclear infrastructure accelerate industry demand.

“We are delighted to welcome DEI and their entire team of nuclear professionals to the Allied family,” said Dean Sack, Chief Executive Officer of Allied Power. “DEI’s ability to make nuclear reactor operation, maintenance, and waste management safer and more cost-effective directly complements the Allied footprint of work in the nuclear power industry. We look forward to growing this footprint by utilizing the deep nuclear industry expertise of DEI.”

“At DEI, we share the Allied team’s commitment to servicing critically important nuclear industry infrastructure and supporting the deployment of new nuclear generation assets, including small modular reactors,” said Mike Little, Chief Executive Officer of DEI. “Our diversified suite of power plant services uniquely complements Allied and RSCS’s existing capabilities and creates an industry-leading group of companies providing safe and cost-effective services to the nuclear industry. The added scale and offerings will provide our employees and customers with significant long-term opportunities, and we are excited to partner with the Allied and Bernhard teams.”

“We are in the middle of a nuclear energy renaissance that requires increasingly specialized expertise and innovative solutions to meet today’s energy demands and support long-term national energy security and the energy transition,” said Mark Spender, a Partner of Bernhard Capital. “The combination of DEI with Allied and RSCS creates a leading platform delivering safe, mission-critical and cost-effective services and technology for a diverse and growing base of operator and power generation clients.”

Allied was advised by Kirkland & Ellis LLP on the transaction. DEI was advised by Baird and Greenberg Traurig, LLP.
