MATADOR RESOURCES COMPANY REPORTS THIRD QUARTER 2022

RESULTS AND RAISES FULL YEAR 2022 GUIDANCE

DALLAS, Texas, October 25, 2022 -- Matador Resources Company (NYSE: MTDR) (“Matador” or the “Company”) today reported financial and operating results for the third quarter of 2022. A short slide presentation summarizing the highlights of Matador’s third quarter 2022 earnings release is also included on the Company’s website at www.matadorresources.com on the Events and Presentations page under the Investor Relations tab.

Management Summary Comments

Joseph Wm. Foran, Matador’s Founder, Chairman and CEO, commented, “On both our website and the webcast planned for tomorrow’s earnings conference call is a set of six slides identified as ‘Chairman’s Remarks’ (Slides A through F) to add color and detail to my remarks. We invite you to review these slides in conjunction with my comments below, which are intended to provide context for the third quarter 2022 results compared to Matador’s stated goals for the year.

Third Quarter 2022 Results Above Expectations

“The third quarter of 2022 was another outstanding quarter for Matador highlighted by production and operating results above our expectations (see Slide A). We are on path to achieve our primary aims for the year to increase shareholder value by the following efforts:

•Growing the fixed dividend and returns to shareholders;

•Reducing debt; and

•Increasing production, reserves and midstream assets.

“Notably, Matador’s growing midstream business, including our 51%-owned joint venture San Mateo Midstream and our new acquisition Pronto Midstream, which is now fully integrated, has delivered strong results in the third quarter highlighted by all-time quarterly highs for third-party midstream revenues and water handling volumes (see Slide B). The team’s strong execution continues to help us deliver wells both on time and on budget across approximately 450 miles of pipeline in our midstream business.

Debt Reduced, Credit Ratings Upgraded and Quarterly Dividend Doubled

“In the last two years, Matador has reduced its outstanding debt by $775 million or over half of our then total revolving debt and bond debt outstanding of $1.525 billion. Now, Matador’s reserves-based revolving credit facility has been completely repaid, and Matador has repurchased $300 million of its outstanding bond debt in a series of open market transactions, reducing its outstanding bond debt from $1.05 billion at December 31, 2021 to $750 million at October 25, 2022 (see Slide C). Matador is a stronger company than it was two years ago. Matador’s leverage ratio has declined from 2.9x at year-end 2020 to 0.2x at the end of the third quarter of 2022, marking Matador’s lowest leverage ratio in over ten years as a public company. Matador expects to continue using a portion of its free cash flow to continue opportunistically reducing its bond debt. At September 30, 2022, Matador has over $400 million of cash in the bank and has available the optionality to pursue a number of opportunities and strategic options going forward.

“In September and October, we were also pleased to announce that all three of Matador’s credit rating agencies—Moody’s, S&P and Fitch—upgraded Matador’s corporate credit rating (see Slide D). Matador has now transitioned from being a ‘single B’ company to a ‘double B’ company across the board. These upgrades reflect our commitment to repaying debt, improving capital efficiency, adding to our production profile and increasing Matador’s cash returns to our shareholders. The rating agencies specifically noted the increasing strength of our balance sheet and our strong operational execution in their decisions to upgrade Matador’s credit rating.

“As a result of our confidence in Matador’s growing operational and financial strength and our execution this year, we were very pleased to announce at our Annual Meeting of Shareholders in June the doubling of our fixed cash dividend from $0.20 per share to $0.40 per share on an annualized basis. This higher dividend was first paid in September. Shareholders of record as of November 10, 2022 can expect our next quarterly cash dividend set again at $0.10 per share, or $0.40 per share on an annualized basis, to be paid on December 1, 2022.

Stronger than Expected Production Results in Third Quarter 2022

“During the third quarter of 2022, Matador achieved better than expected average oil and natural gas equivalent production of over 105,000 barrels of oil and natural gas equivalent (“BOE”) per day (see Slide E), which was 4% better than our expectations of approximately 101,000 BOE per day. In addition, Matador’s production has increased by nearly 50% from 73,000 BOE per day in the third quarter of 2020 to over 105,000 BOE per day in the third quarter of 2022.

Seventh Drilling Rig Added in Third Quarter 2022

“During the third quarter of 2022, Matador added a seventh drilling rig, which allowed us to drill the Jim Pat SWD well before the injection permit authorizing the disposal of produced water into this well expired. As a result, Matador was able to boost San Mateo’s salt water disposal capacity and accelerate the timing of the next phase of drilling on its Rodney Robinson leasehold in the western portion of the Antelope Ridge asset area. The next eight high volume Rodney Robinson wells are expected to be turned to sales late in the first quarter or early in the second quarter of 2023. We continue to be very pleased with the well performance and strong economic results across multiple completion intervals throughout the Rodney Robinson leasehold. The arrival of the state-of-the-art seventh rig provides us with additional operational flexibility on drilling deeper wells and longer laterals.

“Matador is pleased with the early performance of the seventh rig, which has enhanced technical specifications highly sought after by the industry. This rig’s increased set-back capabilities, for example, allow for an approximate 10% increase in drill-pipe to be racked in the derrick, while other unique features allow faster walk times on multi-well pads. As Matador continues its push for longer lateral lengths and multi-well pads across its Delaware Basin assets, these advantages should continue to help to minimize drilling days and further improve operational and capital efficiency.

Looking Ahead and Increasing Full Year 2022 Guidance

“Due to the better-than-expected well performance across our Delaware Basin asset areas in the third quarter of 2022, we are increasing the midpoints of our 2022 total oil and natural gas production guidance from 21.7 million barrels to 21.85 million barrels for oil and from 95.5 billion cubic feet to 97.0 billion cubic feet for natural gas (see Slide F).

“The midpoint of our 2022 capital expenditures guidance for drilling, completing and equipping wells remains unchanged at $800 million. Operating efficiencies, which include faster drill times and use of existing facilities, continue to improve and help to mitigate service cost inflationary pressures realized in 2022. Sustainable efficiencies such as improved completion procedures, simultaneous and remote fracturing operations and 100% implementation of dual-fuel fracturing fleets constitute primary drivers against cost inflation by reducing days spent on wells and eliminating the need for certain materials such as diesel fuel.”

Third Quarter 2022 Financial and Operational Highlights

Net Cash Provided by Operating Activities and Adjusted Free Cash Flow

•Third quarter 2022 net cash provided by operating activities was $557.0 million (GAAP basis), leading to third quarter 2022 adjusted free cash flow (a non-GAAP financial measure) of $269.1 million.

2

Net Income, Earnings Per Share and Adjusted EBITDA

•Third quarter 2022 net income (GAAP basis) was $337.6 million, or $2.82 per diluted common share, a 19% sequential decrease from net income of $415.7 million in the second quarter of 2022, but a 66% year-over-year increase from net income of $203.6 million in the third quarter of 2021. The sequential decrease in net income was primarily attributable to the sequential decline in commodity prices in the third quarter of 2022. Matador’s realized oil price was $94.36 per barrel in the third quarter of 2022, a 15% sequential decrease as compared to $111.06 per barrel realized in the second quarter of 2022.

•Third quarter 2022 adjusted net income (a non-GAAP financial measure) was $321.7 million, or adjusted earnings of $2.68 per diluted common share, a 23% sequential decrease from adjusted net income of $415.6 million in the second quarter of 2022, but a 116% year-over-year increase from adjusted net income of $148.6 million in the third quarter of 2021.

•Third quarter 2022 adjusted earnings before interest expense, income taxes, depletion, depreciation and amortization and certain other items (“Adjusted EBITDA,” a non-GAAP financial measure) were $539.7 million, a 19% sequential decrease from $663.8 million in the second quarter of 2022, but an 84% year-over-year increase from $293.8 million in the third quarter of 2021.

Oil, Natural Gas and Total Production Above Expectations

•As summarized in the table below, Matador’s third quarter 2022 average daily oil, natural gas and total production were all above the Company’s expectations. The primary driver behind this outperformance was better-than-expected production from the 15 most recent Stateline and nine most recent Rodney Robinson wells turned to sales this year and increased working interests from several trades completed earlier than anticipated during the third quarter. In addition, several anticipated incremental shut-ins in the Stateline asset area due to offset operator completions were deferred from the third quarter to the fourth quarter of 2022.

Matador now expects to turn to sales 81 gross (64.3 net) operated horizontal wells during 2022, an increase of one gross (0.6 net) wells from the Company’s prior expectations, primarily as a result of completion schedule changes and additional working interests from anticipated acreage trades.

Fourth Quarter 2022 Completions and Production Cadence Update

Fourth Quarter 2022 Estimated Wells Turned to Sales

6

At October 25, 2022, Matador expects to turn to sales 24 gross (15.2 net) operated horizontal wells in the Delaware Basin during the fourth quarter of 2022, consisting of 12 gross (8.7 net) wells in the Ranger asset area, six gross (3.8 net) wells in the Rustler Breaks asset area, four gross (1.7 net) wells in the Antelope Ridge asset area and two gross (1.0 net) wells in the Arrowhead asset area. The Company expects the average completed lateral length of these wells to be approximately 9,500 feet.

Fourth Quarter 2022 Estimated Oil, Natural Gas and Total Oil Equivalent Production

The table below provides Matador’s estimates, as of October 25, 2022, for the anticipated average daily total oil equivalent, oil and natural gas production for the fourth quarter of 2022.

	Q4 2022 Production Estimates
Period	Average Daily Total Production, BOE per day	Average Daily Oil Production, Bbl per day	Average Daily Natural Gas Production, MMcf per day
Q3 2022	105,214	60,163	270.3
Q4 2022	105,500 to 107,500	61,000 to 62,000	267.0 to 273.0

As noted in the table above, Matador expects its average daily total oil and natural gas equivalent production to increase 1% sequentially from 105,214 BOE per day in the third quarter of 2022 to approximately 106,500 BOE per day in the fourth quarter of 2022. As noted above, Matador expects to turn to sales one additional gross well in its Ranger asset area in 2022, as compared to its previous expectations. Because this additional well was added to the Company’s drill schedule as part of a larger batch, the initial production from several other wells in this batch is expected to be later in the fourth quarter, as compared to Matador’s previous expectations. In addition, several anticipated incremental shut-ins in the Stateline asset area due to offset operator completions were deferred from the third quarter to the fourth quarter of 2022.

(4) Third quarter 2022 as compared to third quarter 2021.

Oil Prices

For the fourth quarter of 2022, Matador’s weighted average oil price differential relative to the WTI benchmark price, inclusive of the monthly roll and transportation costs, is anticipated to be in the range of +$0.50 to +$1.50 per barrel, which is lower than the differential of +$2.93per barrel of oil realized in the third quarter of 2022. This compression of the oil price differential in the fourth quarter is primarily attributable to a reduction in the contribution of the monthly roll in the fourth quarter, as compared to the third quarter.

At October 25, 2022, Matador had approximately 2.7 million barrels of oil hedged for the fourth quarter of 2022 using costless collars with a weighted average floor price of approximately $65 per barrel and a weighted average ceiling price of approximately $110 per barrel. Please see Slide 18 in the accompanying slide presentation for a more complete summary of Matador’s current oil derivative positions.

Natural Gas Prices

For the fourth quarter of 2022, Matador’s weighted average natural gas price differential relative to the Henry Hub average daily benchmark price is anticipated to be in the range of ($0.50) to +$0.50 per thousand cubic feet, which is lower than the differential of +$1.27per thousand cubic feet of natural gas realized in the third quarter of 2022. NGL prices declined in the third quarter and are not expected to be as strong in the fourth quarter of 2022, as compared to the third quarter. In addition, the Waha natural gas basis differential began to widen in the third quarter of 2022, and the Company expects it to remain wider in the fourth quarter, as compared to the third quarter. Matador is a two-stream reporter, and the revenues associated with its NGL production are included in the weighted average realized natural gas price. NGL prices do not contribute to or affect Matador’s realized gain or loss on natural gas derivatives.

At October 25, 2022, Matador had approximately 13.2 billion cubic feet of natural gas hedged for the fourth quarter of 2022 using costless collars with a weighted average floor price of approximately $3.68 per MMBtu and a weighted average ceiling price of approximately $7.61 per MMBtu and 2.4 billion cubic feet of natural gas hedged for the first quarter of 2023 using costless collars with a weighted average floor price of approximately $6.00 per MMBtu and a weighted average ceiling price of approximately $14.00 per MMBtu. Please see Slide 18 in the accompanying slide presentation for a more complete summary of Matador’s current natural gas derivative positions.

Operating Expenses

On a unit of production basis:

•Production taxes, transportation and processing expenses decreased 10% sequentially from $8.50 per BOE in the second quarter of 2022 to $7.64 per BOE in the third quarter of 2022. This decrease was primarily attributable to decreased production taxes associated with lower oil and natural gas revenues of $751.4 million reported by Matador in the third quarter. The sequential decrease in oil and natural gas revenues was primarily attributable to the sequential decrease in realized commodity prices, as noted above.

8

•Lease operating expenses increased 11% sequentially from $3.95 per BOE in the second quarter of 2022 to $4.38 per BOE in the third quarter of 2022.The increase is primarily attributable to the increased number of wells being both operated by Matador and by other operators (where Matador owns a working interest) and to operating cost inflation between the two periods.

•General and administrative expenses increased 18% sequentially from $2.42 per BOE in the second quarter of 2022 to $2.85 per BOE in the third quarter of 2022. This increase is primarily due to the sequential decrease in production as well as the employee stock awards that are based on the value of Matador’s stock but that are settled in cash. General and administrative expenses in the third quarter reflect an increase in stock-based compensation expense associated with these cash-settled stock awards, the values of which are remeasured at each reporting period. These cash-settled stock award amounts increased due to the fact that Matador’s share price increased 5% from $46.59 at June 30, 2022 to $48.92 at September 30, 2022. Matador’s share price as of October 24, 2022 was $66.71.

San Mateo’s operations in the third quarter of 2022 were highlighted by better-than-expected operating and financial results. These strong results reflect not only better-than-expected volumes delivered by Matador during the third quarter of 2022, but also increased and stronger-than-expected volumes delivered by other San Mateo customers as a result of several new business opportunities recently awarded to San Mateo.

Operationally, water handling volumes achieved in the third quarter of 2022 were all-time highs for San Mateo and are shown in the table below, along with other San Mateo throughput volumes, as compared to the second quarter of 2022 and the third quarter of 2021. The volumes in the table do not include the full quantity of volumes that would have otherwise been delivered by certain San Mateo customers subject to minimum volume commitments (although partial deliveries were made in each period), but for which San Mateo recognized revenues during each period.

San Mateo Throughput Volumes	Q3 2022	Q2 2022	Sequential(1)		Q3 2021	YoY(2)
Natural gas gathering, MMcf per day	285	293	(3)	%	248	15	%
Natural gas processing, MMcf per day	280	292	(4)	%	232	21	%

Financial Results

During the third quarter of 2022, San Mateo achieved strong financial results as described below.

•Net income (GAAP basis) of $33.6 million, a 20% sequential decrease from $41.8 million in the second quarter of 2022, but a 14% year-over-year increase from $29.5 million in the third quarter of 2021.

•Adjusted EBITDA (a non-GAAP financial measure) of $47.6 million, a 10% sequential decrease from $52.9 million in the second quarter of 2022, but a 17% year-over-year increase from $40.8 million in the third quarter of 2021.

•Net cash provided by San Mateo operating activities (GAAP basis) of $38.3 million, leading to San Mateo adjusted free cash flow (a non-GAAP financial measure) of $16.4 million.

Primarily as a result of San Mateo and Pronto Midstream activity, Matador achieved third-party midstream services revenues of $24.7 million, an all-time quarterly high and a 13% sequential increase from $21.9 million in the second quarter of 2022, and a 21% year-over-year increase from $20.5 million in the third quarter of 2021.

Capital Expenditures

Capital expenditures for Pronto Midstream and Matador’s portion of San Mateo’s capital expenditures were $14.7 million in the third quarter of 2022, 39% below the Company’s estimate of $24 million for the quarter mostly due to the timing of projects underway during the quarter with most of these costs currently expected to be incurred in the fourth quarter of 2022. During the fourth quarter of 2022, the Company expects to incur midstream capital expenditures of approximately $22 million associated with Pronto Midstream expansion and with San Mateo’s new midstream business opportunities and with new San Mateo infrastructure to handle anticipated increased volumes from Matador and other customers.

Supplemental Non-GAAP Financial Measures

Adjusted EBITDA

This press release includes the non-GAAP financial measure of Adjusted EBITDA. Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and external users of the Company’s consolidated financial statements, such as industry analysts, investors, lenders and rating agencies. “GAAP” means Generally Accepted Accounting Principles in the United States of America. The Company believes Adjusted EBITDA helps it evaluate its operating performance and compare its results of operations from period to period without regard to its financing methods or capital structure. The Company defines, on a consolidated basis and for San Mateo, Adjusted EBITDA as earnings before interest expense, income taxes, depletion, depreciation and amortization, accretion of asset retirement obligations, property impairments, unrealized derivative gains and losses, certain other non-cash items and non-cash stock-based compensation expense and net gain or loss on asset sales and impairment. Adjusted EBITDA is not a measure of net income or net cash provided by operating activities as determined by GAAP. All references to Matador’s Adjusted EBITDA are those values attributable to Matador Resources Company shareholders after giving effect to Adjusted EBITDA attributable to third-party non-controlling interests, including in San Mateo.

Adjusted EBITDA should not be considered an alternative to, or more meaningful than, net income or net cash provided by operating activities as determined in accordance with GAAP or as an indicator of the Company’s operating performance or liquidity. Certain items excluded from Adjusted EBITDA are significant components of understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure. Adjusted EBITDA may not be comparable to similarly titled measures of another company because all companies may not calculate Adjusted EBITDA in the same manner. The following table presents the calculation of Adjusted EBITDA and the reconciliation of Adjusted EBITDA to the GAAP financial measures of net income and net cash provided by operating activities, respectively, that are of a historical nature. Where references are pro forma, forward-looking, preliminary or prospective in nature, and not based on historical fact, the table does not provide a reconciliation. The Company could not provide such reconciliation without undue hardship because such Adjusted EBITDA 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 future income taxes, full-cost ceiling impairments, unrealized gains or losses on derivatives and gains or losses on asset sales and impairment. For the same reasons, the Company is unable to address the probable significance of the unavailable information, which could be material to future results.

Adjusted Net Income and Adjusted Earnings Per Diluted Common Share

This press release includes the non-GAAP financial measures of adjusted net income and adjusted earnings per diluted common share. These non-GAAP items are measured as net income attributable to Matador Resources Company shareholders, adjusted for dollar and per share impact of certain items, including unrealized gains or losses on derivatives, the impact of full cost-ceiling impairment charges, if any, and non-recurring transaction costs for certain acquisitions or other non-recurring expense items, along with the related tax effect for all periods. This non-GAAP financial information is provided as additional information for investors and is not in accordance with, or an alternative to, GAAP financial measures. Additionally, these non-GAAP financial measures may be different than similar measures used by other companies. The Company believes the presentation of adjusted net income and adjusted earnings per diluted common share provides useful information to investors, as it provides them an additional relevant comparison of the Company’s performance across periods and to the performance of the Company’s peers. In addition, these non-GAAP financial measures reflect adjustments for items of income and expense that are often excluded by industry analysts and other users of the Company’s financial statements in evaluating the Company’s performance. The table below reconciles adjusted net income and adjusted earnings per diluted common share to their most directly comparable GAAP measure of net income attributable to Matador Resources Company shareholders.

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

18

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.

The table below reconciles adjusted free cash flow to its most directly comparable GAAP measure of net cash provided by operating activities. All references to Matador’s adjusted free cash flow are those values attributable to Matador shareholders after giving effect to adjusted free cash flow attributable to third-party non-controlling interests, including in San Mateo.
