Atlas Energy Solutions Announces Order of 240 Megawatts of Power Generation Equipment to Provide Long-term Power Solutions

Austin, TX – November 3, 2025 – Atlas Energy Solutions Inc. (NYSE: AESI) (“Atlas” or the “Company”) today announced that it has placed an order of 240 megawatts (“MW”) of power generation equipment from a blue-chip equipment provider to facilitate the evolution of its power business into a provider of long-term power solutions to a diversified customer base scanning the breadth of the economy. The equipment package will feature units with nameplate capacity of 4 MW per engine and is scheduled to be delivered in late 2026.

John Turner, President & CEO, commented, “The pace at which customer demand for long-term power solutions is growing continues to accelerate. Over the past few months, our tangible opportunity set has expanded and continues to do so daily. To meet this demand, we found it necessary to commit to near-term equipment orders. With this package, we expect to meet our target of 400 MW of power generation capacity deployed by early 2027, the majority of which we expect to be under long-term contracts. While this is our first order of power equipment that is designed to be installed in long-term, behind-the-meter applications, based on customer conversations, I expect it to the first of multiple orders as we continue to establish ourselves as a trusted partner in the power solutions space.”
