Matador Resources Announces Successful RBL Redetermination and Increase in San Mateo Bank Commitments

Matador Resources Company (NYSE: MTDR) (“Matador”) is pleased to announce (i) the successful, unanimous redetermination of the borrowing base under Matador’s reserves-based loan credit facility (the “RBL”) at $3.25 billion by the nineteen members of Matador’s bank group and (ii) that the sixteen lenders under San Mateo Midstream, LLC’s (“San Mateo”) revolving credit facility have unanimously agreed to not only renew their commitment but also to increase their commitments by $250 million from $850 million to $1.10 billion.

Unanimous Lender Support for Borrowing Base Redetermination

Matador is pleased to formally announce that as part of the fall 2025 redetermination process, Matador’s nineteen commercial lenders unanimously reaffirmed the Company’s borrowing base under its RBL at $3.25 billion. Matador’s ‘elected commitment’ remained constant at $2.25 billion, but Matador did achieve a slight reduction in its borrowing costs under the RBL.

Joseph Wm. Foran, Matador’s Founder, Chairman and CEO, commented, “We are very pleased to receive the unanimous support from our bank group for Matador’s RBL borrowing base redetermination as well as the increased commitments in the San Mateo credit facility. This support reflects our ongoing commitment to repaying debt, improving capital efficiency, increasing the growth of our production profile and continuing to strengthen and improve our operational execution. In total, Matador has now paid down $311 million in borrowings under the RBL during the first nine months of 2025 to a balance of $285 million as of September 30, 2025. In addition, Matador has reduced its debt-to-EBITDA leverage ratio to less than 1.0x. Accordingly, Matador has approximately $2 billion in available liquidity as of September 30, 2025. We express our appreciation to each of our nineteen banks for their continued support and especially to PNC Bank for their administrative efficiency as our lead bank under the RBL.”

Lender Commitments Increased Under San Mateo’s Revolving Credit Facility

Matador is also pleased to announce that the lender commitments under San Mateo’s revolving credit facility have been increased by 29% from $850 million to $1.10 billion. San Mateo, which is Matador’s midstream joint venture owned 51% by Matador and 49% by Five Point Infrastructure LLC, consists of 650 miles of three-stream pipelines, 720 million cubic feet per day of natural gas processing capacity and 475,000 barrels per day of water disposal capacity in Southeast New Mexico and West Texas. This system provides essential flow assurance for Matador and other producers in the Delaware Basin through oil gathering and transportation, natural gas gathering, treating and processing and water gathering and disposal services across the northern Delaware Basin.

Brian J. Willey, Matador’s Executive Vice President – Midstream, commented, “The $250 million increase in lender commitments under San Mateo’s revolving credit facility provides San Mateo with greater operational and financial flexibility. In connection with this increase, we welcomed one new lender to join San Mateo’s sixteen-member bank group led by Truist Bank. We greatly value the strong banking relationships we enjoy with our lenders, which have been pivotal to the growth and success of San Mateo since its formation in 2017. We wish to express our sincere appreciation to each of our banks for their confidence and unanimous support, and we look forward to continuing to work together to grow San Mateo’s operations.”
