Atlas Energy Solutions Enters Agreement with Caterpillar Inc. to Secure Power Generation Assets Through 2029 to Support Private Grid Development Pipeline

Atlas Energy Solutions Inc. (NYSE:AESI) ("Atlas" or the "Company") today announced the execution of a Global Framework Agreement (the "GFA") with Caterpillar Inc. (NYSE:CAT) ("CAT") covering approximately 1.4 gigawatts of incremental power generation assets, with orders scheduled for 2027 through 2029. With the successful deployment of these assets, Atlas forecasts to own and operate approximately 2.0 gigawatts of power generation assets by 2030.

The incremental capacity will be fulfilled through a portfolio of large load, power dense natural gas reciprocating generator sets, including CG260-16 stationary units designed for behind the meter ("BTM") deployments and G3520 series units suitable for both BTM and bridge power applications. Under the agreement, Atlas will provide rolling demand forecasts and commit to aggregate purchase obligations of approximately $840 million over the term of the agreement, while CAT will reserve corresponding manufacturing capacity in-line with agreed upon forecasts.

John Turner, President & CEO, commented, "Atlas' core power strategy of connecting private capital to private grid systems is dependent upon a secure supply of the right equipment, deployable at the right time. This agreement ensures supply certainty, pricing discipline, and execution reliability as we build out this platform. Atlas is well positioned in the behind-the-meter market at a pivotal moment. The build-out of AI infrastructure and manufacturing reshoring are driving unprecedented power demand growth, and grid limitations are pushing industrial customers to seek alternative power solutions through private grid systems. This structural supply--demand imbalance presents a compelling multi-year growth opportunity for Atlas, and we look forward to partnering with CAT in the execution of this strategy and delivering reliable, resilient, private grid solutions to our customers."

Long-Term Power Strategy Presentation
