"We are pleased to build upon the strong momentum PROPWR has established since its inception. This agreement marks a major milestone in the expansion of our strategic collaboration with Caterpillar, reinforcing our position as a leader in high-efficiency power-as-a-service solutions," said Travis Simmering, President of PROPWR.

"By leveraging the global reputation of the Caterpillar brand and the proven success of our historical collaboration, we are poised to enhance reliability, drive operational excellence, and deliver exceptional value to our customers," said Sam Sledge, ProPetro's Chief Executive Officer. "This collaboration will be a key enabler in achieving PROPWR's long-term objectives and sustaining our rapid growth trajectory."

Under this agreement, PROPWR agrees to purchase at least 1.5 gigawatts of incremental power generation assets, with the option to bring the total to approximately 2.1 gigawatts of additional power generation capacity over the next five years. When combined with the approximately 550 megawatts previously ordered, PROPWR is positioned to have approximately 2.6 gigawatts of power generation capacity delivered by year-end 2031 and fully deployed in 2032.

"This agreement reflects the strength of our long‑standing collaboration with ProPetro and a shared focus on helping customers meet growing power needs with reliable, scalable solutions," said Tara Rossman, Senior Vice President of Caterpillar Oil & Gas and Marine. "As demand from data centers and other energy‑intensive applications continue to accelerate, Caterpillar is committed to supporting PROPWR with proven power generation technologies and the global scale needed to execute over the long term."

PROPWR's approach to funding purchases under this agreement is both disciplined and strategically diversified. Its preferred source of capital will continue to be free cash flow generated by ProPetro's completions business, with additional contributions anticipated from the ongoing growth of the power segment. This internal funding is supplemented by access to flexible financing facilities with attractive terms, which the company intends to use prudently to maintain financial flexibility and low near-term leverage. Recent actions, such as ProPetro's successful equity offering, have further strengthened its balance sheet and enhanced liquidity. The company is also actively evaluating additional financing options to support this framework agreement and intends to capitalize on favorable conditions while maintaining flexibility and optionality in its capital structure.
