Full year 2018 natural gas production was near the high end of the Company’s updated full year 2018 natural gas guidance of 47.0 to 47.4 billion cubic feet. Matador’s full year 2018 guidance for oil, natural gas and total oil equivalent production was updated on October 31, 2018, thus, the second upward revision in 2018.

• Full year 2018 average daily oil equivalent production increased 34% year-over-year to 52,100 BOE per day (59% oil) as compared to the full year 2017. Average daily oil production increased 42% to 30,500 barrels per day and average daily natural gas production increased 24% to 129.6 million cubic feet per day, each as compared to the full year 2017.

• Full year 2018 Delaware Basin average daily oil equivalent production increased 54% to 45,200 BOE per day (62% oil) as compared to the full year 2017. Delaware Basin average daily oil production increased 56% to 28,000 barrels per day and Delaware Basin average daily natural gas production increased 51% to 103.3 million cubic feet per day, each as compared to the full year 2017.

• Full year 2018 net income (GAAP basis) was $274.2 million, or $2.41 per diluted common share, a year-over-year increase of 118% from $125.9 million, or $1.23 per diluted common share, for the full year 2017.

• Full year 2018 adjusted net income (a non-GAAP financial measure) was $184.0 million, or $1.62 per diluted common share, a year-over-year increase of 151% from $73.4 million, or $0.72 per diluted common share, for the full year 2017.

• Full year 2018 Adjusted EBITDA, a non-GAAP financial measure, was $553.2 million, a year-over-year increase of 65% from $336.1 million for the full year 2017. Full year 2018 Adjusted EBITDA of $553.2 million was near the high end of the Company’s full year 2018 guidance for Adjusted EBITDA of $535.0 to $555.0 million, as updated and revised upwards for the second time on October 31, 2018.

Management Comments

Joseph Wm. Foran, Matador’s Chairman and CEO, commented, “Both financially and operationally, 2018 was the best year in Matador’s history, and the Board and I wish to commend the staff for their hard work, planning and record-setting accomplishments on behalf of all Matador shareholders and other stakeholders. During the past two years, Matador has more than doubled its oil production and proved oil and natural gas reserves, while adding approximately 55,000 net high-quality leasehold and mineral acres to its Delaware Basin position. In that same time period, we have essentially tripled the throughput volumes associated with our midstream affiliate, San Mateo, and yesterday, we announced a second strategic midstream transaction with our partner, Five Point, to significantly expand San Mateo’s operations throughout Eddy County, New Mexico. We believe our numerous operational, land and financial achievements in 2018 have placed Matador in a strong position for continued value creation in the years ahead. Simultaneous with this earnings release, we have also released today our 2019 operating plan and 2019 market guidance. As you will see in that companion release, our plans for 2019 and beyond reflect a tightly integrated strategy focused not only on increasing the value of our oil and natural gas leasehold and mineral assets in the Delaware Basin, but also on building and enhancing the value of San Mateo.

“As a result of the sharp decline in oil prices during the fourth quarter of 2018 and the changing financial circumstances in the industry, Matador started taking various steps to mitigate its anticipated 2019 cash flow outspend. First, we announced in late January 2019 plans to reduce our operated drilling program by releasing the drilling rig we had been operating in South Texas since early October 2018. We have since completed our South Texas drilling operations for now, and this rig was released in early February. As further noted in our January press release, in 2019, we plan to focus on executing the highest rate of return opportunities across our Delaware Basin properties and midstream operations, while continuing to be mindful of our balance sheet as we have always done. Second, Matador is continuing to narrow its spending gap by converting certain non-cash assets to cash and by divesting of portions of its non-core assets, particularly in South Texas and in the Haynesville shale. Thus far, this effort is expected to result in approximately $50 to $55 million in cash to Matador’s balance sheet from a number of transactions closed or under contract to close in the very near future, not including the $50 million capital carry we expect Five Point to provide as part of the San Mateo expansion. Third, we will also consider monetizing other assets, such as certain royalty, mineral and non-core midstream interests, as value-creating opportunities arise. Fourth, we are working to implement practices to improve capital efficiency in our own operations during 2019, including through potential reductions in service costs, additional multi-well pad drilling, increasing the number of longer laterals and increased use of in-basin sand in our hydraulic fracturing operations, among other steps.

“At the same time, we believe the Matador Board and staff have done a good job in the past of adding significant value per share with the capital entrusted to us by our shareholders. We believe our operating and financial results over the last seven years of being a public company clearly evidence this fact. In 2019, we expect to continue creating value for Matador shareholders in four primary ways: (1) maintaining Matador’s practice of profitable growth at a measured pace in its selective drilling, completions and production activities; (2) expanding the growth and footprint of our midstream operations through our San Mateo midstream affiliate through creative deal structures that mitigate capital spending, as evidenced by yesterday’s announcement of a planned expansion of San Mateo that includes a significant capital carry for Matador; (3) increasing the value of Matador’s acreage position through our continued delineation and development of the acreage, by making strategic trades to enable us to more efficiently develop the acreage and by engaging in value-adding acquisition and sales opportunities; and (4) highlighting and enhancing the value of Matador’s mineral and royalty positions. We look forward to meeting the operational and financial challenges of the coming year and to position Matador for further growth, prosperity and balance sheet strength in 2020 and beyond. We encourage our shareholders and others to take time to study the 2019 operating plan that we released today and to call us with your questions and thoughts.”

Proved Reserves, Standardized Measure and PV-10

The following table summarizes Matador’s estimated total proved oil and natural gas reserves at December 31, 2018, 2017 and 2016.

	At December 31,
	2018			2017			2016
Estimated proved reserves:(1)(2)
Oil (MBbl)(3)	123,401			86,743			56,977

(1) Numbers in table may not total due to rounding.
(2) Matador’s estimated proved reserves, Standardized Measure and PV-10 were determined using index prices for oil and natural gas, without giving effect to derivative transactions, and were held constant throughout the life of the properties. The unweighted arithmetic averages of the first-day-of-the-month prices for the period from January through December 2018 were $62.04 per Bbl for oil and $3.10 per MMBtu for natural gas, for the period from January through December 2017 were $47.79 per Bbl for oil and $2.98 per MMBtu for natural gas and for the period from January through December 2016 were $39.25 per Bbl for oil and $2.48 per MMBtu for natural gas. These prices were adjusted by property for quality, energy content, regional price differentials, transportation fees, marketing deductions and other factors affecting the price received at the wellhead. Matador reports its proved reserves in two streams, oil and natural gas, and the economic value of the natural gas liquids associated with the natural gas is included in the estimated wellhead price on those properties where the natural gas liquids are extracted and sold.
(3) One thousand barrels of oil.
(4) One billion cubic feet of natural gas.
(5) One thousand barrels of oil equivalent, estimated using a conversion ratio of one barrel of oil per six thousand cubic feet of natural gas.
(6) PV-10 is a non-GAAP financial measure. For a reconciliation of PV-10 (non-GAAP) to Standardized Measure (GAAP), please see “Supplemental Non-GAAP Financial Measures.”

The reserves estimates presented for each period in the table above were prepared by the Company’s internal engineering staff and audited by an independent reservoir engineering firm, Netherland, Sewell & Associates, Inc. These reserves estimates were prepared in accordance with the Securities and Exchange Commission’s rules for oil and natural gas reserves reporting and do not include any unproved reserves classified as probable or possible that might exist on Matador’s properties.

For a reconciliation of PV-10 (non-GAAP) to Standardized Measure (GAAP), please see “Supplemental Non-GAAP Financial Measures” below.

Proved Reserves at December 31, 2018 Increased 41% Year-Over-Year

• Matador’s total proved oil and natural gas reserves increased 41% year-over-year from 152.8 million BOE (57% oil, 45% proved developed, 84% Delaware Basin), consisting of 86.7 million barrels of oil and 396.2 billion cubic feet of natural gas, at December 31, 2017 to 215.3 million BOE (57% oil, 44% proved developed,

6

89% Delaware Basin), consisting of 123.4 million barrels of oil and 551.5 billion cubic feet of natural gas, at December 31, 2018. Oil, natural gas and total proved reserves at December 31, 2018 were each all-time highs for Matador. Estimated total proved oil and natural gas reserves more than doubled over the last two years, increasing 104% from 105.8 million BOE (54% oil, 41% proved developed, 75% Delaware Basin) at December 31, 2016.

• At December 31, 2018, the Standardized Measure and PV-10, a non-GAAP financial measure, of Matador’s total proved oil and natural gas reserves were $2.25 billion and $2.58 billion, respectively, an increase of 79% and 93% from $1.26 billion and $1.33 billion, respectively, at December 31, 2017. At December 31, 2018, the oil and natural gas prices used to estimate total proved reserves were $62.04 per barrel and $3.10 per MMBtu, respectively, as compared to $47.79 per barrel and $2.98 per MMBtu, respectively, at December 31, 2017.

• At December 31, 2018, Matador’s total proved oil and natural gas reserves included 24.8 million BOE in proved undeveloped reserves, with a Standardized Measure of $249 million and a PV-10 of $286 million, attributable to portions of the 8,400 gross and net acres of leasehold that the Company acquired in the Bureau of Land Management New Mexico Oil and Gas Lease Sale in September 2018 (the “BLM Acquisition”). The PV-10 of $286 million at December 31, 2018 already represents almost 75% of the aggregate lease bonus of $387 million Matador paid to acquire these properties, not to mention the significant future midstream value of these properties to San Mateo. Matador estimates that the proved undeveloped reserves assigned to these properties at December 31, 2018 reflect only a fraction of the oil and natural gas reserves that may be ultimately attributable to these properties as a result of future development operations on this leasehold.

• Accounting for Matador’s 2018 oil equivalent production of 19.0 million BOE, Matador’s total proved reserves increased 81.5 million BOE in 2018, or approximately 4.3 times its 2018 annual production. The Company’s proved reserves to production ratio was 11.3 at December 31, 2018, an increase of 5% from 10.8 at December 31, 2017. The overall increase in Matador’s proved reserves of 81.5 million BOE during 2018 included aggregate upward revisions to prior estimates of 11.3 million BOE, resulting primarily from better-than-expected well performance associated with a number of wells throughout the Delaware Basin.

Delaware Basin Drilling Inventory Increased 26% Year-Over-Year

• At December 31, 2018, Matador had identified 5,442 gross (2,472 net) potential locations for future drilling on its Delaware Basin acreage, an increase of 26% in net identified locations, as compared to 4,630 gross (1,958 net) locations at December 31, 2017. The Company estimates that it may be able to operate as many as 3,451 gross (2,278 net) of these locations. As with prior estimates, Matador’s updated Delaware Basin inventory estimates assume one-mile laterals drilled at 160-acre spacing in most formations. This increase in identified well locations was primarily attributable to the Company’s acquisition of approximately 30,000 net acres of additional leasehold and mineral interests in the Delaware Basin during 2018.

Significant Well Results

The following table highlights the 24-hour IP test results from certain of Matador’s operated wells recently completed and turned to sales in the Delaware Basin. Matador continues to be pleased with the aggregate well performance across its acreage position in the Delaware Basin and particularly with a number of better-than-expected well results during the fourth quarter of 2018.

In the Antelope Ridge asset area, Matador was very pleased with the results of its Nina Cortell Federal Com #201H (Nina Cortell #201H) well, a Wolfcamp A-Lower test in the northwestern portion of the Antelope Ridge asset area. The Nina Cortell #201H well flowed 1,753 BOE per day (78% oil), including 1,372 barrels of oil per day and 2.3 million cubic feet of natural gas per day, during a 24-hour IP test. This well was yet another successful test of the Wolfcamp A-Lower formation in this area, further evidencing the prospectivity of this target across much of the Company’s acreage in the Antelope Ridge asset area.

In the Rustler Breaks asset area, Matador was also pleased with the results of its David Edelstein State Com #223H (Edelstein #223H) well drilled and completed in the southwest portion of its Rustler Breaks asset area. The Edelstein #223H well, a Wolfcamp B-Blair test, flowed 3,375 BOE per day (29% oil), including 970 barrels of oil per day and 14.4 million cubic feet of natural gas per day, during a 24-hour IP test. The Edelstein #223H well was Matador’s second two-mile lateral in the Rustler Breaks asset area. The Michael Collins 11-23S-27E RB #201H (Collins #201H) well was another strong Wolfcamp A-XY completion in the northwest portion of the Rustler Breaks asset area. The Collins #201H well flowed 2,125 BOE per day (78% oil), including 1,665 barrels of oil per day and 2.8 million cubic feet of natural gas per day, during a 24-hour IP test.

Matador continues to enjoy particular success with the longer laterals (greater than one mile) it has drilled recently in the southern portion of its Wolf asset area. The Wolf 80-TTT-B33 WF #206H and #208H (Wolf #206H and #208H) wells, both Wolfcamp A-XY completions, tested 2,509 BOE per day (41% oil) and 2,514 BOE per day (39% oil), respectively, during 24-hour IP tests, with the Wolf #208H 24-hour IP test being the Company’s highest reported to date in the Wolf asset area. The Wolf #206H and #208H wells had completed lateral lengths of approximately 5,600 and 6,200 feet, respectively. These wells compared favorably to the strong results for the Wolf 80-TTT-B33-WF #205H and #207H (Wolf #205H and #207H) wells, both also Wolfcamp A-XY completions, previously announced in Matador’s second quarter 2018 earnings release on August 1, 2018. The Wolf #205H and #207H wells have each produced approximately 320,000 BOE (58% oil) in their first nine months of production.

Drilling and Completion Activities

During the fourth quarter of 2018, Matador continued to focus primarily on the exploration, delineation and development of the Company’s Delaware Basin acreage position in Loving County, Texas and Lea and Eddy Counties, New Mexico. Matador began 2018 operating six drilling rigs in the Delaware Basin and continued to operate six drilling rigs there throughout the fourth quarter of 2018. During the fourth quarter, these six operated drilling rigs were deployed across the Company’s Delaware Basin asset areas, with two rigs in the Rustler Breaks asset area, one rig in the Wolf and Jackson Trust asset areas, one rig in the Arrowhead, Ranger and Twin Lakes asset areas and two rigs in the Antelope Ridge asset area.

In early October 2018, the Company added a seventh operated drilling rig to its drilling program on a short-term contract in South Texas to drill up to 10 wells, primarily in the Eagle Ford shale, to take advantage of higher oil and natural gas prices in South Texas, to conduct at least one exploratory test of the Austin Chalk formation and to validate and to hold by production almost all of its remaining undeveloped Eagle Ford acreage. This rig operated in South Texas throughout the fourth quarter of 2018 and into early 2019. When drilling operations were finalized on the ninth well in early February 2019, this rig was released and was not moved to the Delaware Basin as the Company had previously anticipated. One of the Eagle Ford shale wells was completed and turned to sales during the fourth quarter of 2018, and the remaining eight wells, including one well drilled in the Austin Chalk, are expected to be completed and turned to sales late in the first quarter or early in the second quarter of 2019.

Production Results

Average daily oil equivalent production increased 2% sequentially from 54,600 BOE per day (59% oil) in the third quarter of 2018 to 55,500 BOE per day (60% oil) in the fourth quarter of 2018, a record quarterly high for Matador.

Average daily oil production increased 4% sequentially from 32,300 barrels per day in the third quarter of 2018 to 33,500 barrels per day in the fourth quarter of 2018, also a record quarterly high and above the Company’s expectations for oil production at the high end of its estimated range for the fourth quarter.

Average daily natural gas production decreased 1% sequentially from 133.8 million cubic feet per day in the third quarter of 2018 to 132.3 million cubic feet per day in the fourth quarter of 2018, consistent with the Company’s expectations and between the midpoint and high end of its estimated range for natural gas production for the fourth quarter. As noted in its second quarter 2018 earnings release provided on August 1, 2018, Matador had projected that its natural gas production would decline slightly in the third and fourth quarters of 2018 from the peak rate of 139.2 million cubic feet of natural gas per day achieved in the second quarter of 2018.

Realized Commodity Prices

Matador’s weighted average realized oil price, excluding derivatives, decreased 14% sequentially from $57.15 per barrel in the third quarter of 2018 to $49.09 per barrel in the fourth quarter of 2018, due primarily to a sharp decline of more than 40% in crude oil prices during the fourth quarter of 2018.  Matador’s weighted average oil price differentials relative to the West Texas Intermediate benchmark narrowed from ($12.36) per barrel in the third quarter of 2018 to ($10.18) per barrel in the fourth quarter of 2018, inclusive of transportation costs.  Although the Midland-Cushing basis differentials have narrowed further recently, Matador still expects its weighted average realized oil price differential to be in the range of ($6.00) to ($7.00) per barrel in the first quarter of 2019, inclusive of transportation costs.

Matador’s weighted average realized natural gas price, excluding derivatives, decreased 8% sequentially from $3.77 per thousand cubic feet in the third quarter of 2018 to $3.47 per thousand cubic feet in the fourth quarter of 2018, due primarily to a significant widening in Waha-Henry Hub basis differentials and a decrease in natural gas liquids prices in the fourth quarter. Matador realized a weighted average natural gas price differential of ($0.26) per thousand cubic feet below the average NYMEX Henry Hub natural gas price in the fourth quarter of 2018, as compa

red to an uplift of $0.90 per thousand cubic feet above the average NYMEX Henry Hub natural gas price in the third quarter of 2018.

Matador’s realized price for its Delaware Basin natural gas production is exposed to the Waha-Henry Hub basis differentials. These basis differentials widened significantly in the fourth quarter of 2018 to more than $4.00 per MMBtu at certain times in the latter part of the quarter. Fortunately, the Waha-Henry Hub basis differentials have narrowed considerably since the fourth quarter of 2018 to approximately $1.50 per MMBtu and are expected to continue to improve throughout 2019. Matador’s Delaware Basin natural gas production is expected to remain primarily exposed to the Waha-Henry Hub basis differentials until the fourth quarter of 2019, when the Kinder Morgan Gulf Coast Express Pipeline Project (“GCX Pipeline”) is expected to become operational in October 2019. Matador has secured firm natural gas transportation and sales on the GCX Pipeline for an average of approximately 110,000 to 115,000 million British Thermal Units per day at a price based upon Houston Ship Channel pricing. Matador is a two-stream reporter, and the revenues associated with its natural gas liquids production are included in the weighted average realized natural gas price.

Operating Expenses

On a unit-of-production basis:

• Production taxes, transportation and processing expenses decreased 12% sequentially from $4.02 per BOE in the third quarter of 2018 to $3.53 per BOE in the fourth quarter of 2018. This decrease was attributable primarily to lower production taxes associated with the 11% sequential decrease in oil and natural gas revenues.

• Lease operating expenses per BOE increased 2% from $4.48 per BOE in the third quarter of 2018 to $4.56 per BOE in the fourth quarter of 2018. The increase was attributable to higher repair and workover expenses during the quarter, partially offset by lower salt water disposal costs as more of our oil and natural gas producing wells in the Wolf and Rustler Breaks asset areas are now connected to salt water disposal wells operated by San Mateo via pipeline, thus eliminating higher priced salt water trucking costs. Lease operating expenses were better than the Company’s expectations for the quarter of between $5.00 and $5.25 per BOE as the Company was able to effectively manage costs and take advantage of increased economies of scale associated with our higher daily oil equivalent production.

• General and administrative expenses per BOE decreased 28% from $3.67 per BOE in the third quarter of 2018 to $2.66 per BOE in the fourth quarter of 2018, much better than the Company’s expectations. This decrease resulted primarily from economies of scale and the 34% increase in total oil equivalent production during 2018, but also reflects lesser bonus compensation paid to Matador’s principal executives in 2018, as compared to 2017, which is reflected in the Company’s fourth quarter general and administrative expenses. General and administrative expenses of $2.66 per BOE were the lowest in any quarter since Matador’s initial public offering in February 2012. Excluding $0.67 per BOE in non-cash stock-based compensation expenses, Matador’s cash-based general and administrative expenses were $1.99 per BOE in the fourth quarter of 2018.

• Depletion, depreciation and amortization expenses per BOE increased 1% sequentially from $14.02 per BOE in the third quarter of 2018 to $14.19 per BOE in the fourth quarter of 2018. This slight increase was attributable to increased depreciation expense associated with increased midstream property and equipment during the fourth quarter. Depreciation expenses associated with midstream operations were $4.1 million, or $0.80 per BOE, in the fourth quarter of 2018, as compared with $2.6 million, or $0.52 per BOE, in the third quarter of 2018.

Wells Completed and Turned to Sales

Fourth Quarter 2018

10

During the fourth quarter of 2018, Matador completed and turned to sales a total of 47 gross (22.9 net) wells in its various operating areas, one of which was a vertical well. This total was comprised of 23 gross (20.2 net) operated wells and 24 gross (2.7 net) non-operated wells. These operated and non-operated totals for wells turned to sales were consistent with Matador’s updated fourth quarter 2018 estimates as provided on October 31, 2018, with the exception that only one gross (1.0 net) Eagle Ford shale well was completed and turned to sales during the fourth quarter of 2018, as opposed to the Company’s original expectations that three gross (3.0 net) Eagle Ford shale wells would be completed and turned to sales in the fourth quarter. Although only one Eagle Ford shale well was turned to sales in the fourth quarter, five additional Eagle Ford shale wells and one Austin Chalk well were drilled and waiting on completion or in progress at December 31, 2018, as drilling operations progressed much faster on these wells than the Company expected when the South Texas drilling program was initiated in October 2018.

In the fourth quarter of 2018, most of the Company’s operated and non-operated drilling and completions activities were undertaken in the Delaware Basin, with the exception of the seventh operated rig operating in South Texas, as summarized in the table below.

Full Year 2018

For the year ended December 31, 2018, Matador completed and turned to sales a total of 153 gross (75.5 net) wells in its various operating areas, two of which were vertical wells. This total was comprised of 83 gross (67.8 net) operated wells and 70 gross (7.7 net) non-operated wells. These operated and non-operated totals for wells turned to sales are consistent with Matador’s updated full year 2018 estimates as provided on October 31, 2018, with the exception that only one gross (1.0 net) Eagle Ford shale well was completed and turned to sales during the fourth quarter of 2018, as opposed to the Company’s original expectations that three gross (3.0 net) Eagle Ford shale wells would be completed and turned to sales in the fourth quarter.

Essentially all of the Company’s operated and non-operated drilling and completions activities for the year ended December 31, 2018 were undertaken in the Delaware Basin, as summarized in the table below.

San Mateo Highlights and Update

On February 25, 2019, Matador announced a strategic midstream transaction with a subsidiary of Five Point Energy LLC (“Five Point”) designed to expand San Mateo’s operations in the Delaware Basin and, specifically, to expand its three-pipe midstream offering throughout Eddy County, New Mexico (please see Matador’s press release dated February 25, 2019 for additional information). As part of this transaction, Matador dedicated to San Mateo acreage in the Stebbins and surrounding leaseholds in the Arrowhead asset area (the “Greater Stebbins Area”), as well as Matador’s new Stateline asset area, totaling approximately 25,500 gross acres. The Stateline asset area includes the 2,800 gross and net acres that Matador acquired in Eddy County, New Mexico along the New Mexico - Texas border as part of the BLM Acquisition. In return, Five Point has committed to carry Matador for $125 million of the first $150 million in capital expenditures (i.e., Matador will pay $25 million and Five Point will pay $125 million of the first $150 million of capital expenditures). As part of this transaction, Five Point has also provided Matador the opportunity to earn deferred performance incentives of up to $150 million over the next five years as Matador executes its operational plans in and around the Stateline area and the Greater Stebbins Area, plus additional performance incentives for Matador, as Manager of San Mateo, to bring in additional third-party customers. At closing, Matador and Five Point continued to own 51% and 49% of San Mateo, respectively.

During the fourth quarter of 2018, San Mateo had a number of notable accomplishments, several of which have been previously reported, including the following.

• In October 2018, a subsidiary of San Mateo entered into a long-term agreement with a producer in Eddy County, New Mexico for the gathering and processing of such producer’s natural gas. At the time of the announcement, San Mateo had entered into contracts to provide firm gathering and processing for over 80% of the designed inlet capacity of 260 million cubic feet of natural gas per day at its Black River cryogenic natural gas processing plant (the “Black River Processing Plant”) in Eddy County, New Mexico (please see Matador’s October 16, 2018 press release for additional information).

12

• In mid-December 2018, a subsidiary of San Mateo placed into service its crude oil gathering and transportation system in Eddy County, New Mexico (the “Rustler Breaks Oil Pipeline System”). The Rustler Breaks Oil Pipeline System includes approximately 17 miles of 10-inch diameter crude oil gathering and transportation pipelines from origin points in Eddy County, New Mexico to an interconnect with Plains Pipeline, L.P. (please see San Mateo’s December 19, 2018 press release for additional information). With the Rustler Breaks Oil Pipeline System in service, Matador expects to improve its oil price realizations in the Rustler Breaks asset area by as much as $1.00 to $1.50 per barrel through the elimination of higher priced trucking costs. Matador currently has on pipe almost all of its oil production from the Wolf and Rustler Breaks asset areas, which comprised approximately 70% of the Company’s Delaware Basin oil production in the fourth quarter of 2018 (please see Matador’s December 19, 2018 press release for additional information).

• During the fourth quarter of 2018, San Mateo began drilling its sixth commercial salt water disposal well in the Rustler Breaks asset area in Eddy County, New Mexico. This salt water disposal well was completed and water injection began in mid-February 2019. San Mateo currently has nine commercial salt water disposal wells (six in the Rustler Breaks asset area and three in the Wolf asset area) with approximately 250,000 barrels per day of total designed salt water disposal capacity.

• In December 2018, San Mateo entered into a new $250 million credit facility led by the Bank of Nova Scotia (the “San Mateo Credit Facility”), and including all participants in Matador’s existing revolving credit facility led by the Royal Bank of Canada. The San Mateo Credit Facility includes an accordion feature, which could expand the commitments of the lenders to up to $400 million. The San Mateo Credit Facility is non-recourse to Matador. Upon the closing of the San Mateo Credit Facility, San Mateo borrowed $195 million, which was distributed 51% to Matador and 49% to Five Point to reimburse prior capital commitments to San Mateo. The distribution to Matador is being used to reduce outstanding borrowings under the Company’s revolving credit facility and to fund future exploration and production activities. At December 31, 2018, San Mateo had approximately $220 million in borrowings outstanding.

During the fourth quarter of 2018, San Mateo also:

• Gathered an average of 149 million cubic feet of natural gas day in the Wolf and Rustler Breaks asset areas, a sequential increase of 14%, as compared to 131 million cubic feet per day in the third quarter of 2018, and a year-over-year increase of 41%, as compared to 106 million cubic feet per day in the fourth quarter of 2017.

• Processed an average of 112 million cubic feet of natural gas per day at the Black River Processing Plant, a sequential increase of 19%, as compared to 94 million cubic feet per day in the third quarter of 2018, and a year-over-year increase of 75%, as compared to 64 million cubic feet per day in the fourth quarter of 2017.

• Disposed of an average of 153,000 barrels of salt water per day in the Wolf and Rustler Breaks asset areas, essentially flat sequentially, as compared to 155,000 barrels per day in the third quarter of 2018, and a year-over-year increase of 84%, as compared to 83,000 barrels per day in the fourth quarter of 2017.

• Gathered an average of 10,000 barrels of oil per day in the Wolf and Rustler Breaks asset areas, a sequential increase of 54%, as compared to 6,500 barrels per day in the third quarter of 2018 and as compared to minimal oil volumes gathered in the fourth quarter of 2017.

San Mateo’s throughput volumes for natural gas gathering and processing have increased significantly in early 2019. For the month of January 2019, San Mateo gathered an average of 174 million cubic feet of natural gas per day and processed an average of 133 million cubic feet of natural gas per day. In addition, as a result of the completion of the interconnect between the Rustler Breaks Oil Pipeline System and Plains Pipeline, L.P. in mid-December 2018, San Mateo gathered an average of 26,000 barrels of oil per day in January 2019.

Delaware Basin Acreage Acquisitions

13

Matador continued its “brick by brick” strategy for adding to its acreage position in the fourth quarter of 2018, acquiring approximately 3,000 net leasehold and mineral acres in and around its existing acreage positions in the Delaware Basin, including approximately 500 net mineral acres. In 2018, Matador added approximately 29,800 net leasehold and mineral acres in the Delaware Basin, bringing the Company’s total Delaware Basin leasehold and mineral position to approximately 222,200 gross (132,000 net) acres at December 31, 2018.

Please see the table below for a breakdown of Matador’s leasehold and mineral position in the Delaware Basin by asset area.

Delaware Basin Asset Area	Gross Acres	Net Acres
Rustler Breaks	45,300	26,200
Stateline	2,800	2,800
Wolf/Jackson Trust	14,400	10,700
Antelope Ridge	20,500	17,300
Arrowhead	60,100	25,700
Ranger	34,200	17,500
Twin Lakes	44,300	31,300
Other	600	500
Total	222,200	132,000

As of December 31, 2018, Matador had acquired its entire Delaware Basin leasehold and mineral position for an all-in weighted average cost of approximately $11,000 per net acre, excluding small amounts of production acquired.

Delaware Basin Mineral Position

Matador has also been successful in acquiring mineral acres in the Delaware Basin over the last few years. At December 31, 2018, the Company held approximately 6,900 net minerals acres (also included in the net leasehold and mineral acres reported in the table above), or approximately 11,200 net royalty acres, across its various asset areas, including under a number of tracts that the Company operates, particularly in the Rustler Breaks asset area.

Please see the table below for a breakdown of the Company’s net mineral and net royalty acres by asset area.

	Net	Net
Delaware Basin Asset Area	Mineral Acres	Royalty Acres(1)
Rustler Breaks	4,800	7,500
Wolf/Jackson Trust	1,000	1,800
Antelope Ridge	700	1,200
Arrowhead	100	100
Ranger	100	200
Twin Lakes	200	400
Total	6,900	11,200
(1) Net royalty acres normalized for a 12.5% (1/8th) royalty interest. For example, 1.0 net mineral acre with a 25% Royalty interest = 2.0 net royalty acres; 1.0 net mineral acre with a 20% royalty interest = 1.6 net royalty acres; and 1.0 net mineral acre with a 12.5% royalty interest = 1.0 net royalty acre.

Fourth Quarter 2018 and Full Year 2018 Capital Expenditures and Liquidity Position

During the fourth quarter of 2018, Matador incurred capital expenditures, excluding land and mineral acquisitions, of $209.7 million, including $187.8 million for drilling, completing and equipping wells (“D/C/E”) and $21.9

14

million for midstream investments, which primarily represented Matador’s proportionate share of San Mateo’s fourth quarter capital expenditures of $39.2 million. D/C/E capital expenditures associated with Matador’s operated wells were slightly below the Company’s estimates in the fourth quarter of 2018; however, owing to Matador’s participation in several more non-operated wells (both completed and turned to sales and in progress) than originally estimated, the Company incurred approximately $11.0 million in additional D/C/E capital expenditures during the fourth quarter.

For the year ended December 31, 2018, Matador incurred capital expenditures, excluding land and mineral acquisitions, of $771.8 million, including $686.3 million for D/C/E capital expenditures and $85.5 million for midstream investments, which primarily represented Matador’s proportionate share of San Mateo’s full year 2018 capital expenditures of $163.7 million and which was within the range of Matador’s 2018 guidance for midstream investments. For the year ended December 31, 2018, Matador’s aggregate D/C/E and midstream capital expenditures were at the high end of the Company’s 2018 updated guidance for aggregate capital expenditures of $770 million, primarily as a result of the additional non-operated well participation described above.

At December 31, 2018, the Company had approximately $84.0 million in cash and restricted cash, $40.0 million in borrowings outstanding under its revolving credit agreement (which has a borrowing base of $850.0 million with an elected borrowing commitment of $500.0 million) and approximately $3.0 million in outstanding letters of credit, and San Mateo had $220.0 million in aggregate borrowings outstanding under the San Mateo Credit Facility. At February 26, 2019, the Company had $80.0 million in borrowings outstanding and approximately $13.6 million in outstanding letters of credit under its revolving credit agreement, and San Mateo had $220.0 million in borrowings outstanding and $16.2 million in outstanding letters of credit under the San Mateo credit facility. For accounting purposes, all borrowings outstanding under the San Mateo Credit Facility and all interest payments made pursuant to that facility are recorded at 100% of their carrying value in the Company’s consolidated financial statements, even though the San Mateo Credit Facility is non-recourse to Matador.

Hedging Positions

Matador increased its oil hedges in early 2019, and at February, 26, 2019, Matador had approximately 50% of its anticipated oil production hedged for the remainder of 2019 based on the midpoint of its 2019 production guidance.

For full year 2019, Matador had approximately 15% of its anticipated natural gas production hedged based on the midpoint of its 2019 production guidance.

Matador also has in place Midland-Cushing oil basis differential swaps for 2020 for approximately 1.2 million barrels at ($0.15) per barrel.

The following is a summary of the Company’s open derivative financial instruments for 2019 at January 1, 2019, pro forma for oil hedges added through February 26, 2019.

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 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, prepayment premium on extinguishment of debt and net gain or loss on asset sales and inventory impairment. Adjusted EBITDA is not a measure of net income (loss) or net cash provided by operating activities as determined by GAAP.

Adjusted EBITDA should not be considered an alternative to, or more meaningful than, net income (loss) 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 (loss) 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 inventory impairments. For the same reasons, we are unable to address the probable significance of the unavailable information, which could be material to future results.

Adjusted Net Income (Loss) and Adjusted Earnings (Loss) Per Diluted Common Share

This press release includes the non-GAAP financial measures of adjusted net income (loss) and adjusted earnings (loss) per diluted common share.  These non-GAAP items are measured as net income (loss) 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 gains or losses or transaction costs for certain acquisitions and divestitures or other non-recurring expense items, along with the related tax effects 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 (loss) and adjusted earnings (loss) 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 securities analysts and other users of the Company’s financial statements in evaluating the Company’s performance. The table below reconciles adjusted net income (loss) and adjusted earnings (loss) per diluted common share to their most directly comparable GAAP measure of net income (loss) attributable to Matador Resources Company shareholders.

PV-10

PV-10 is a non-GAAP financial measure and generally differs from Standardized Measure, the most directly comparable GAAP financial measure, because it does not include the effects of income taxes on future net revenues. PV-10 is not an estimate of the fair market value of the Company’s properties. Matador and others in the industry use PV-10 as a measure to compare the relative size and value of proved reserves held by companies and of the potential return on investment related to the companies’ properties without regard to the specific tax characteristics of such entities. PV-10 may be reconciled to the Standardized Measure of discounted future net cash flows at such dates by adding the discounted future income taxes associated with such reserves to the Standardized Measure.
