ProPetro Announces Expansion of Revolving Credit Facility

ProPetro Holding Corp. (“ProPetro” or “the Company”) (NYSE: PUMP) today announced the expansion of its existing asset-based loan facility (the “Amended ABL”) to $300 million – a 50% increase over the previous cap of $200 million. The Amended ABL will provide additional flexibility in connection with the Company’s previously announced acquisition of Pioneer Natural Resources Company’s (NYSE: PXD) (“Pioneer”) pressure pumping assets. In addition, ProPetro will become a strategic long-term service provider to Pioneer, providing pressure pumping and related services for a term of up to 10 years. The transaction remains on schedule for closing at the end of this month.

Pro-forma for the Pioneer transaction, the Company will have a net debt to LTM EBITDA ratio of below 1.0x and plans to remain at this level or below for the foreseeable future.

Jeff Smith, Chief Financial Officer, commented, “We look forward to strong a start to 2019 as we quickly begin to benefit from the enhanced scale afforded by our strategic transaction and long-term agreement with Pioneer. The expansion of our credit facility is another important step in our commitment to maintaining financial discipline, a strong balance sheet and ample liquidity. We appreciate the continued support of our banking partners who recognize the strong long-term fundamentals and unique positioning of our business as a true industry leader.”
