Entry into a Material Definitive Agreement

Supply Contract for Power Generation Equipment

On July 22, 2026, Liberty Advanced Equipment Technologies LLC (the “Purchaser”), a wholly owned subsidiary of Liberty Energy Inc. (the “Company”), entered into an equipment supply contract with Caterpillar Inc. (“Caterpillar”) for the purchase of power generation equipment, including engines and certain balance of plant equipment (collectively, the “Equipment”), for the Company’s prospective data center and other distributed power projects (the “Supply Contract”). The Supply Contract has a purchase price of approximately $801 million (the “Contract Price”). The Contract Price does not include any import taxes, import duties, customs duties, tariffs, and other similar charges, which are payable by the Purchaser to the extent due.

The payment schedule for the Contract Price includes a payment due at the time of ordering the Equipment with the remaining payments being made in installments in connection with the assembly and delivery of the Equipment. Delivery of the Equipment is scheduled to occur beginning in 2027 through early 2029.

The Supply Contract provides that Caterpillar has limited its liability under specified conditions and that Caterpillar is subject to paying liquidated damages under certain conditions for failure to achieve delivery milestones and performance guarantees. The Purchaser may terminate the Supply Contract with respect to individual engines for continued failure to achieve delivery milestones, and for convenience subject to payment of defined cancellation charges. In addition, either party may terminate the Supply Contract for material breach and may be entitled to receive refunds, termination payments, and/or damages.

The foregoing description of the Supply Contract does not purport to be complete and is qualified in its entirety by reference to the full text of the Supply Contract, a copy of which will be filed as an exhibit to the Company’s Quarterly Report on Form 10-Q for the quarter ending September 30, 2026.
