Item 1.01 Entry Into a Material Definitive Agreement.

On April 28, 2026 (the “Effective Date”), ProPetro Energy Solutions, LLC (“PROPWR”), a Delaware limited liability company and a wholly owned subsidiary of ProPetro Holding Corp. (the “Company”), a Delaware corporation, entered into a Global Framework Agreement (the “GFA”) with Caterpillar Inc. (“Caterpillar”), a Delaware corporation, pursuant to which Caterpillar will reserve approximately 1.5 gigawatts (“Reserved Capacity”) of incremental power generation equipment (the “Equipment”), comprised of a mix of Caterpillar power generation solutions and configurations, and PROPWR will commit to purchase the Equipment from Caterpillar or certain Caterpillar authorized dealers (“Participating Dealers”) for a minimum aggregate purchase obligation at signing of approximately $1.1 billion as well as the option to acquire up to an additional approximate 600 megawatts beginning on the Effective Date and ending on December 31, 2031 (the “Term”). The initial purchase price for the Equipment does not include balance of plant and is subject to adjustments including for annual escalations, taxes, tariffs affecting the cost of the Equipment and any other fees and adjustments agreed to by PROPWR.

The GFA may be extended by mutual agreement and each party has certain termination rights upon advance written notice, that do not affect the existing orders placed under the GFA.

If PROPWR’s forecasted demand increases, PROPWR may request an increase in Reserved Capacity, which Caterpillar may grant in its sole discretion. If, in any year during the Term, PROPWR does not order 100% of its purchase obligations by the designated order deadline (“Shortfall Amount”), PROPWR must pay Caterpillar a fee equal to 75% of the price at which PROPWR had otherwise agreed to purchase such Equipment. However, if Caterpillar sells Equipment constituting the Shortfall Amount within 12 months of the Shortfall Amount invoice date, PROPWR is entitled to a credit toward future purchases under the GFA equal to 85% of the Shortfall Amount.

The foregoing description of the GFA does not purport to be complete and is qualified in its entirety by reference to the full text of the GFA, a copy of which will be filed as an exhibit to our Quarterly Report on Form 10-Q for the second quarter of 2026.
