• Additional 3-Year Extension Will Provide Landfill and Ash Pond Management and Material Handling Operations to Miami Fort and Zimmer Power Plants in Ohio of Approximately 180,000 Tons of Ash Annually
• Approximately 400,000 Tons of Fly Ash Per Year from Both Sites Will be Recycled and Sold for Beneficial Use in Portland Cement

Charah^® Solutions, Inc. (NYSE:CHRA) (the "Company"), a leading provider of mission-critical environmental services and byproduct sales to the power generation industry, today announced that it has been awarded a three-year contract extension with Luminant. Charah Solutions will now provide fly ash sales and material handling operations for Luminant's Miami Fort Power Plant and Zimmer Power Plant in southern Ohio through 2027, when both plants are expected to be retired.

Charah Solutions will continue to manage the onsite landfill and impoundment operations under its existing contract with Luminant, including material loading, hauling and disposal of approximately 180,000 tons of ash annually from both plants for an additional three years through 2027. In addition, Charah Solutions will be responsible for the beneficiation and utilization of approximately 400,000 tons of fly ash each year. The Company has the right to sell and market 100% of the high quality, specification grade Class F fly ash from both power plants for beneficial use via the Company's MultiSource® materials network. Utilizing its nationwide truck, rail and barge shipping platform, Charah Solutions recycles and markets the fly ash to concrete product manufacturers and ready-mix concrete producers throughout Ohio, Kentucky, Indiana, Pennsylvania, New Jersey, New York, Connecticut, North Carolina, Florida, Mississippi, Louisiana and Oklahoma, providing customers with multiple supply options of high-quality fly ash.

Charah Solutions' MultiSource materials network is a unique distribution system of more than 40 locations nationwide, with complimentary international sourcing and distribution, which ensures the Company's ability to provide a continuous and reliable supply of supplementary cementitious materials for ready mix concrete producers, cement producers and other customers throughout the U.S.

As a sustainability leader in utility services for over 30 years, Charah Solutions is dedicated to preserving our natural resources in an environmentally conscious manner through ash marketing projects. Sustainability is a core value at Charah Solutions, and our business is focused on developing innovative solutions to complex environmental issues for the betterment of the planet, the communities in which we operate and our customers. The beneficial use of fly ash in concrete products offers benefits in both the hardened and plastic state of concrete. In addition to improving the finish product quality, using fly ash in concrete products and other applications not only eliminates the need to dispose of fly ash in landfills it also significantly reduces the overall carbon footprint and conserves our natural resources by replacing materials that would otherwise have to be mined and processed for these products.

With the increasing focus on CO₂ emissions and reduction of greenhouse gasses, more states, regulatory authorities and concrete producers are realizing the environmental benefit of substituting fly ash for Portland cement. Utilizing recycled fly ash as a substitute for energy-intensive Portland cement results in a reduction of CO₂ emissions. Recycled fly ash also results in cost savings versus Portland cement for ready-mix producers.

Miami Fort Power Plant is a 1,020-megawatt coal-fired power plant located in North Bend, Ohio, while Zimmer Power Plant has a capacity of 1,300 megawatts and is located in Moscow, Ohio.

According to Scott Sewell, Charah Solutions President and CEO, "We have been proud to partner with Luminant on its sustainability efforts for many years and are delighted to extend our relationship at these Ohio sites through 2027. We have dramatically reduced the need to landfill fly ash at Miami Fort and Zimmer through our ongoing partnership, saving Luminant both expense and valuable landfill space while lowering their risk. Charah Solutions is nationally recognized in the power generation industry as a total solutions company, providing unparalleled service and innovation to meet the evolving and increasingly complex needs of our utility partners. As a result of this expanded agreement, Charah Solutions will continue to provide a reliable supply of high-quality fly ash to ready mix concrete producers in the Midwest, Northeast and deep South through our MultiSource network."
