Matador Resources Company (NYSE:MTDR) ("Matador" or the "Company") announces the successful bolt-on acquisition of 5,154 net undeveloped acres in the core of the Delaware Basin as part of the Bureau of Land Management (BLM) Oil and Gas Lease Sale this week.

Joseph Wm. Foran, Matador's Founder, Chairman and CEO, commented, "Matador is pleased to announce a $1.1 billion expansion of its premier Delaware Basin asset base in Southeast New Mexico through the recent BLM Lease Sale. The company acquired 5,154 net undeveloped acres, all of which are in the ‘core-of-the-core' of the Delaware Basin and are strategic and highly complementary to Matador's current acreage position. This acquisition not only extends the amount and the duration of Matador's high-quality inventory and reserve base but also enhances the Company's current assets with increased operating efficiencies. These lease acquisitions lend themselves to extended reach laterals of three miles or more, leveraging of existing facilities and infrastructure with Matador's existing field teams, and increased midstream value from potential future volume additions in the Delaware Basin.

HIGHLIGHTS

Prime Location: Acquired acreage located in most prolific areas of Delaware Basin, with nine or more discrete prospective formations
Strategic Alignment to Current Asset Base: Acreage directly adjacent to existing operated units, enabling further operating efficiencies in already established cost-advantaged operating areas with current completed cost per lateral foot averages 10-20% below Matador's corporate average
Improved Economics and Lease Terms: 87.5% net revenue interest with 10-year term across all depths
San Mateo Connectivity: Key tracts and associated wells and volumes strategically located near existing infrastructure expected to be additive to San Mateo's volume throughput and growing revenue streams
Locations and Efficiencies: Adds over 141 net operated locations (normalized to 2-mile laterals), including extended reach laterals, U-Turn well designs, multi-well developments and completions, emerging horizons and targets, with opportunities for enhanced water recycling processes and natural gas takeaway capacity
Maintenance of Strong Balance Sheet: Purchase price of approximately $1.143 billion implies approximately $7.3 million per location after accounting for anticipated midstream value and is expected to be funded through cash on hand and existing credit facility

Mr. Foran further commented, "We believe our proven track record of value creation over the years de-risks this transaction as evidenced by our 2018 acquisition of the State line and Rodney Robinson Federal tracts. To date, Matador has already recovered all associated capital invested in lease acquisitions, drilling, and completions associated with those tracts, as well as generating an additional $1.9 billion in returns from these projects. We have full confidence that our reservoir, geology, midstream, and operating teams will maximize the value of these new tracts in a similar manner.

"Matador has fully repaid its reserve-based lending (RBL) facility, providing ample liquidity for this transaction. Furthermore, under our current operating plan, we anticipate full-year 2026 adjusted free cash flow to approach $1.2 billion (assuming strip oil and natural gas pricing as of early May 2026). This strong cash generation gives us clear line of sight to substantially pay down this acquisition by year-end 2026 and to fully pay down the RBL in the first half of 2027.

"We would like to thank our shareholders, bondholders, directors, banks, and staff here in Dallas and the field for their continued support and recognition of Matador's asset quality, cash flow and our expectations for another record year for the Company. We hope to see you at our Annual Meeting on June 11, 2026, here in Dallas where we will have more operational and financial news to share."

Matador undertakes no obligation to update these forward-looking statements to reflect events or circumstances occurring after the date of this press release, except as required by law, including the securities laws of the United States and the rules and regulations of the SEC.

All forward-looking statements are qualified in their entirety by this cautionary statement.

Adjusted Free Cash Flow

This press release includes the non-GAAP financial measure of adjusted free cash flow. This non-GAAP item is measured, on a consolidated basis for the Company and for San Mateo, as net cash provided by operating activities, adjusted for changes in working capital and cash performance incentives that are not included as operating cash flows, less cash flows used for capital expenditures, adjusted for changes in capital accruals. On a consolidated basis, these numbers are also adjusted for the cash flows related to non-controlling interest in subsidiaries that represent cash flows not attributable to Matador shareholders. Adjusted free cash flow should not be considered an alternative to, or more meaningful than, net cash provided by operating activities as determined in accordance with GAAP or an indicator of the Company's liquidity. Adjusted free cash flow is used by the Company, securities analysts and investors as an indicator of the Company's ability to manage its operating cash flow, internally fund its D/C/E capital expenditures, pay dividends and service or incur additional debt, without regard to the timing of settlement of either operating assets and liabilities or accounts payable related to capital expenditures. Additionally, this non-GAAP financial measure may be different than similar measures used by other companies. The Company believes the presentation of adjusted free cash flow provides useful information to investors, as it provides them an additional relevant comparison of the Company's performance, sources and uses of capital associated with its operations across periods and to the performance of the Company's peers. In addition, this non-GAAP financial measure reflects adjustments for items of cash flows that are often excluded by securities analysts and other users of the Company's financial statements in evaluating the Company's cash spend. Where references are pro forma, forward-looking, preliminary or prospective in nature, and not based on historical fact, a reconciliation has not been provided. The Company could not provide such reconciliation without undue hardship because such Adjusted Fre Cash Flow numbers are estimations, approximations and/or ranges. In addition, it would be difficult for the Company to present a detailed reconciliation on account of many unknown variables for the reconciling items, including net change in operating assets and liabilities and net change in capital accruals.
