DEAR SHAREHOLDERS & FRIENDS

What a difference a year makes! One year 
ago, as I wrote this letter in April 2020, our 
nation and our industry were in the early 
days of the Coronavirus pandemic and 
oil prices had fallen below $20 per barrel, 
resulting from an oil “price war” between 
Russia and Saudi Arabia. Those days, and 
the year 2020 overall, were probably the 
(cid:147)(cid:156)(cid:195)(cid:204)(cid:3)(cid:86)(cid:133)(cid:62)(cid:143)(cid:143)(cid:105)(cid:152)(cid:125)(cid:136)(cid:152)(cid:125)(cid:3)(cid:62)(cid:152)(cid:96)(cid:3)(cid:96)(cid:136)(cid:118)(cid:119)(cid:86)(cid:213)(cid:143)(cid:204)(cid:3)(cid:156)(cid:118)(cid:3)(cid:147)(cid:222)(cid:3)(cid:123)(cid:120)(cid:135)

year oil and gas career. Last April, I laid 
out our plans to address and overcome 

those challenges. Today, as you will read throughout this 2020 
Annual Report, the Matador team came together to meet the many 
challenges we faced in 2020 in exemplary fashion. As a result, 
(cid:31)(cid:62)(cid:204)(cid:62)(cid:96)(cid:156)(cid:192)(cid:3)(cid:119)(cid:152)(cid:136)(cid:195)(cid:133)(cid:105)(cid:96)(cid:3)(cid:211)(cid:228)(cid:211)(cid:228)(cid:3)(cid:62)(cid:195)(cid:3)(cid:62)(cid:3)(cid:76)(cid:105)(cid:204)(cid:204)(cid:105)(cid:192)(cid:3)(cid:62)(cid:152)(cid:96)(cid:3)(cid:195)(cid:204)(cid:192)(cid:156)(cid:152)(cid:125)(cid:105)(cid:192)(cid:3)(cid:86)(cid:156)(cid:147)(cid:171)(cid:62)(cid:152)(cid:222)(cid:112)(cid:192)(cid:105)(cid:62)(cid:96)(cid:222)(cid:3)(cid:204)(cid:156)(cid:3)

Now, as I write this letter in April 2021, the Coronavirus pandemic 
is starting to abate, many of us are getting vaccinated, global 
oil demand is increasing, Matador’s production and reserves are

initiation of the dividend policy as noted above. Matador’s 2021 
drilling program will focus on our federal properties, which include 
some of the best acreage in the Delaware Basin, including the 
continued development of our Stateline asset area, continued 
drilling of the Rodney Robinson leasehold and further development 
of the Greater Stebbins Area. We began the year operating 
three rigs in the Delaware Basin but have recently added a fourth 
operated rig to our drilling program. In 2021, Matador should also 
begin earning additional performance incentives from our joint 
venture partner in San Mateo, as we develop Matador’s properties 
in the Stateline asset area and connect new wells to San Mateo’s

and natural gas terms used in this Annual Report, see the “Glossary of Oil and Natural Gas Terms” included 
in this Annual Report.

GENERAL

We are an independent energy company engaged in the exploration, development, production and acquisition 

of oil and natural gas resources in the United States, with an emphasis on oil and natural gas shale and other 
unconventional plays. Our current operations are focused primarily on the oil and liquids-rich portion of the Wolfcamp
and Bone Spring plays in the Delaware Basin in Southeast New Mexico and West Texas. We also operate in 
the Eagle Ford shale play in South Texas and the Haynesville shale and Cotton Valley plays in Northwest Louisiana. 
Additionally, we conduct midstream operations, primarily through our midstream joint venture, San Mateo, 
in support of our exploration, development and production operations and provide natural gas processing, oil
transportation services, oil, natural gas and produced water gathering services and produced water disposal
services to third parties.

We are a Texas corporation founded in July 2003 by Joseph Wm. Foran, Chairman and CEO. Mr. Foran began
his career as an oil and natural gas independent in 1983 when he founded Foran Oil Company with $270,000 in 
contributed capital from 17 friends and family members. Foran Oil Company was later contributed to Matador 
Petroleum Corporation upon its formation by Mr. Foran in 1988. Mr. Foran served as Chairman and Chief Executive
Officer of that company from its inception until it was sold in June 2003 to Tom Brown, Inc., in an all cash
transaction for an enterprise value of approximately $388.5 million.

On February 2, 2012, our common stock began trading on the New York Stock Exchange (the “NYSE”) under the
symbol “MTDR.” Prior to trading on the NYSE, there was no established public trading market for our common stock.

Our goal is to increase shareholder value by building oil and natural gas reserves, production and cash flows
and providing midstream services at an attractive rate of return on invested capital. We plan to achieve our goal by,
among other items, executing the following business strategies:

•

•

focus our exploration and development activities primarily on unconventional plays, including the Wolfcamp
and Bone Spring plays in the Delaware Basin;

identify, evaluate and develop additional oil and natural gas plays as necessary to maintain a balanced
portfolio of oil and natural gas properties;

• continue to improve operational and cost efficiencies;

•

identify and develop midstream opportunities that support and enhance our exploration and development
activities and that generate value for San Mateo;

• maintain our financial discipline; and

• pursue opportunistic acquisitions, divestitures and joint ventures.

MATADOR RESOURCES COMPANY 

Despite the precipitous decline in global oil demand resulting from the worldwide spread of COVID-19 in 2020,

which led to a very challenging oil and natural gas price environment, the successful execution of our business
strategies led to increases in our oil and natural gas production and proved oil and natural gas reserves in 2020. We
achieved these results despite reducing our operated drilling rig count from six at the beginning of the year to three 
by the end of the second quarter. We also improved the capital efficiency of our drilling and completion operations 
and achieved several key operational milestones throughout the year (as further described below in “—Exploration 
and Production Segment—Southeast New Mexico and West Texas—Delaware Basin” and “—Midstream Segment”). 
In addition, we concluded several important financing transactions in 2020, including an increase in the elected
commitment under our Credit Agreement (as defined below), the affirmation of the borrowing base and the
restructuring of our oil hedging portfolio. San Mateo also achieved several important milestones in 2020, including
the expansion of its cryogenic natural gas processing plant in Eddy County, New Mexico (the “Black River Processing 
Plant”) and associated pipelines and the merger of San Mateo II with and into San Mateo I. These achievements 
and transactions increased our operational flexibility and opportunities while preserving the strength of our balance 
sheet and our liquidity position.

2020 HIGHLIGHTS

Increased Oil, Natural Gas and Oil Equivalent Production

For the year ended December 31, 2020, we achieved record oil, natural gas and average daily oil equivalent 
production. In 2020, we produced 15.9 million Bbl of oil, an increase of 14%, as compared to 14.0 million Bbl of oil
produced in 2019. We also produced 69.5 Bcf of natural gas, an increase of 14% from 61.1 Bcf of natural gas produced 
in 2019. Our average daily oil equivalent production for the year ended December 31, 2020 was 75,175 BOE per 
day, including 43,526 Bbl of oil per day and 189.9 MMcf of natural gas per day, an increase of 14%, as compared
to 66,203 BOE per day, including 38,312 Bbl of oil per day and 167.4 MMcf of natural gas per day, for the year
ended December 31, 2019. The increase in oil and natural gas production was primarily attributable to our ongoing
delineation and development drilling activities in the Delaware Basin throughout 2020, which offset declining 
production in the Eagle Ford and Haynesville shales. Oil production comprised 58% of our total production (using 
a conversion ratio of one Bbl of oil per six Mcf of natural gas) for both the years ended December 31, 2020 and 
December 31, 2019.

Increased Oil, Natural Gas and Oil Equivalent Reserves

At December 31, 2020, our estimated total proved oil and natural gas reserves were 270.3 million BOE,

including 159.9 million Bbl of oil and 662.3 Bcf of natural gas, an increase of 7% from 252.5 million BOE, including
148.0 million Bbl of oil and 627.2 Bcf of natural gas, at December 31, 2019. The Standardized Measure of our 
total proved oil and natural gas reserves decreased 22% from $2.03 billion at December 31, 2019 to $1.58 billion 
at December 31, 2020. The PV-10 of our total proved oil and natural gas reserves decreased 26% from $2.25 billion at 
December 31, 2019 to $1.66 billion at December 31, 2020. The decreases in our Standardized Measure and PV-10
were primarily a result of the significantly lower weighted average oil and natural gas prices used to estimate proved 
reserves at December 31, 2020, as compared to December 31, 2019. PV-10 is a non-GAAP financial measure. 
For a reconciliation of PV-10 to Standardized Measure, see “—Estimated Proved Reserves.”

Our proved oil reserves grew 8% to 159.9 million Bbl at December 31, 2020 from 148.0 million Bbl at 
December 31, 2019. Our proved natural gas reserves increased 6% to 662.3 Bcf at December 31, 2020 from
627.2 Bcf at December 31, 2019. This growth in oil and natural gas reserves was attributable to our ongoing
delineation and development drilling activities in the Delaware Basin during 2020.

At December 31, 2020, proved developed reserves included 69.6 million Bbl of oil and 323.2 Bcf of natural gas,

and proved undeveloped reserves included 90.3 million Bbl of oil and 339.1 Bcf of natural gas. Proved developed
reserves and proved oil reserves comprised 46% and 59%, respectively, of our total proved oil and natural gas
reserves at December 31, 2020. Proved developed reserves and proved oil reserves comprised 42% and 59%,
respectively, of our total proved oil and natural gas reserves at December 31, 2019.

Operational Highlights

We focus on optimizing the development of our resource base by seeking ways to maximize our recovery

per well relative to the cost incurred and to minimize our operating costs per BOE produced. We apply an analytical 
approach to track and monitor the effectiveness of our drilling and completion techniques and service providers. 
This allows us to better manage operating costs, the pace of development activities, technical applications, the
gathering and marketing of our production and capital allocation. Additionally, we concentrate on our core areas, 
which allows us to achieve economies of scale and reduce operating costs. Largely as a result of these factors, we
believe that we have increased our technical knowledge of drilling, completing and producing Delaware Basin
wells. We expect the Delaware Basin will continue to be our primary area of focus in 2021.

We completed and began producing oil and natural gas from 89 gross (47.8 net) wells in the Delaware Basin 
in 2020, including 53 gross (45.6 net) operated and 36 gross (2.2 net) non-operated wells. At December 31, 2020, 
our total acreage position in the Delaware Basin was approximately 230,600 gross (124,700 net) acres, primarily 
in Loving County, Texas and Lea and Eddy Counties, New Mexico. We have focused our Delaware Basin operations
thus far on the following asset areas: the Wolf and Jackson Trust asset areas in Loving County, Texas, the 
Stateline, Rustler Breaks and Arrowhead asset areas in Eddy County, New Mexico and the Antelope Ridge, Ranger
and Twin Lakes asset areas in Lea County, New Mexico. Our Delaware Basin properties have become the most 
significant component of our asset portfolio. Our average daily oil equivalent production from the Delaware Basin
increased approximately 21% to 67,522 BOE per day (90% of total oil equivalent production), including 41,678 Bbl 
of oil per day (96% of total oil production) and 155.1 MMcf of natural gas per day (82% of total natural gas production),
in 2020, as compared to 55,599 BOE per day (84% of total oil equivalent production), including 35,184 Bbl of oil
per day (92% of total oil production) and 122.5 MMcf of natural gas per day (73% of total natural gas production), in 
2019. We expect our Delaware Basin production to increase in 2021 as we continue the delineation and 
development of these asset areas.

During 2020, we achieved all five significant and important operational milestones in the Delaware Basin we 
set at the beginning of the year. These five operational milestones (as further described below in “—Exploration
and Production Segment—Southeast New Mexico and West Texas—Delaware Basin” and “—Midstream 
Segment”) were:

• we completed and turned to sales the first six Rodney Robinson wells, all of which were two-mile laterals,
in the western portion of our Antelope Ridge asset area, in late March 2020; these six Rodney Robinson
wells have produced in aggregate approximately 2.7 million BOE in approximately 10 months of production;

• we completed and turned to sales the first five Ray State wells, all of which were two-mile laterals, in the

eastern portion of our Rustler Breaks asset area in late May and early June 2020; these five Ray State wells
have produced in aggregate approximately 1.6 million BOE in just over seven months of production;

• we completed and turned to sales five Leatherneck wells in the Stebbins area and surrounding leaseholds
in the southern portion of the Arrowhead asset area (the “Greater Stebbins Area”) in late July and early
August 2020; these five Leatherneck wells have produced in aggregate approximately 1.0 million BOE in
just over six months of production;

   FORM 10-K PART I

 
 
6

MATADOR RESOURCES COMPANY  

• we completed and turned to sales the first 13 Boros wells, all of which were two-mile laterals, in the

eastern portion of the Stateline asset area in a staggered fashion during September 2020; these 13 Boros
wells have produced in aggregate approximately 2.7 million BOE in just over four months of production,
despite a number of these wells being produced on restricted chokes early in their production; and

• San Mateo completed the expansion of the Black River Processing Plant and associated pipelines and

facilities in conjunction with the Boros and Leatherneck wells coming online.

In addition to achieving these five key operational milestones, further operational highlights in the Delaware Basin

(as further described below in “—Exploration and Production Segment—Southeast New Mexico and West Texas—
Delaware Basin”) in 2020 included:

•

•

•

•

•

the ongoing transition to drilling longer laterals, whereby 83% of the operated horizontal wells we
completed and turned to sales in 2020 had lateral lengths greater than one mile, as compared to 29% in
2019 and 9% in 2018;

the continuing improvement in capital efficiency as demonstrated by (i) our average drilling and completion
costs for all operated horizontal wells completed and turned to sales of approximately $850 per lateral
foot in 2020, a decrease of 27% as compared to average drilling and completion costs of $1,165
per lateral foot in 2019 and a decrease of 44% as compared to average drilling and completion costs of
$1,528 per lateral foot in 2018, and (ii) the sequential quarterly decrease in our drilling and completion
costs per lateral foot on operated wells turned to sales throughout 2020, from $1,009 in the first quarter
to $881 in the second quarter to $790 in the third quarter and, finally, to $625 in the fourth quarter;

record-low unit operating costs for lease operating expenses of $3.81 per BOE and general and administrative
expenses of $2.27 per BOE;

in our Wolf asset area, the results from our first Third Bone Spring Carbonate test in the Delaware Basin,
demonstrating the prospectivity of this formation throughout the basin; and

in our Rustler Breaks asset area, the results from our first Third Bone Spring Sand test, demonstrating the
prospectivity of this formation in that asset area.

Financing Highlights

We concluded several important financing transactions in 2020 that increased our operational flexibility and 

opportunities, while preserving the strength of our balance sheet and improving our liquidity position. These 
transactions included:

•

•

•

the amendment of our third amended and restated credit agreement (the “Credit Agreement”)
in February 2020 to reaffirm the borrowing base at $900.0 million, increase our elected borrowing
commitment from $500.0 million to $700.0 million and add two new banks to our lending group;

the reaffirmation of the borrowing base under the Credit Agreement in October 2020; and

the restructuring of a portion of our then-existing 2020 NYMEX West Texas Intermediate (“WTI”) oil
derivative financial instruments in April 2020 to provide additional revenue assurance had oil prices declined
further and help us remain in compliance with our Credit Agreement leverage covenant in 2020.

See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and

Capital Resources” for additional information regarding these financing transactions.

Midstream Highlights

Effective October 1, 2020, together with our joint venture partner, a subsidiary of Five Point Energy LLC (“Five
Point”), we completed the successful merger of San Mateo II with and into San Mateo I. San Mateo is owned 51% 
by us and 49% by Five Point.

San Mateo achieved strong operating results in 2020, highlighted by (i) increased midstream services revenues,

(ii) increased produced water handling volumes and (iii) increased oil gathering and transportation volumes, all as 
compared to 2019. San Mateo’s natural gas gathering and processing volumes declined slightly in 2020 as compared 
to 2019 due to reduced volumes from a significant third-party customer, but, on a quarterly sequential basis,
San Mateo’s natural gas gathering and processing volumes, water handling volumes and oil gathering and
transportation volumes all increased significantly in the fourth quarter of 2020, as compared to the third quarter, as we 
realized the first full quarter of production from the Boros wells in the Stateline asset area and the Leatherneck 
wells in the Greater Stebbins Area.

During the third quarter of 2020, San Mateo completed the construction and successful start-up of the expansion

of the Black River Processing Plant, which added an incremental designed inlet capacity of 200 MMcf of natural
gas per day to the previously designed inlet capacity of 260 MMcf per day for a total designed inlet capacity of
460 MMcf per day. The expanded Black River Processing Plant supports our exploration and development activities
in the Delaware Basin and, at December 31, 2020, was gathering and processing natural gas from the Stateline
asset area and from the Greater Stebbins Area. The Black River Processing Plant also processes natural gas
from our Rustler Breaks asset area and provides natural gas processing services for other San Mateo customers
in the area.

In September 2020, San Mateo also completed and placed in service approximately 43 miles of large diameter 
natural gas gathering pipelines between the Black River Processing Plant and the Stateline asset area (approximately 
24 miles) and the Greater Stebbins Area (approximately 19 miles). In addition, San Mateo completed and placed
in service approximately 19 miles of various diameter crude oil pipelines from certain points of origin in the
Greater Stebbins Area to the existing San Mateo interconnect with a subsidiary of Plains All American Pipeline, 
L.P. (“Plains”) in Eddy County, New Mexico. At December 31, 2020, San Mateo was gathering or transporting 
our oil and natural gas production via pipeline in both the Stateline asset area and the Greater Stebbins Area, as well 
as in the Wolf and Rustler Breaks asset areas. San Mateo was handling our produced water via pipeline in each
of these areas as well.

At December 31, 2020, San Mateo’s midstream system included:

• Natural Gas Assets: 460 MMcf per day of designed natural gas cryogenic processing capacity and

approximately 140 miles of natural gas gathering pipelines in Eddy County, New Mexico and Loving County,
Texas, including 43 miles of large-diameter natural gas gathering lines spanning from the Stateline asset 
area to the Greater Stebbins Area in Eddy County, New Mexico;

• Oil Assets: Three oil central delivery points (“CDP”) with over 100,000 Bbl of designed oil throughput

capacity and approximately 90 miles of oil gathering and transportation pipelines in Eddy County,
New Mexico and Loving County, Texas, as well as a 400,000-acre joint development area with Plains to
gather our and other producers’ oil production in Eddy County, New Mexico; and

• Produced Water Assets: 13 commercial salt water disposal wells and associated facilities with designed 

produced water disposal capacity of 335,000 Bbl per day and approximately 120 miles of produced water
gathering pipelines in Eddy County, New Mexico and Loving County, Texas.

MATADOR RESOURCES COMPANY  

Environmental, Social and Governance (“ESG”) Initiatives

We maintain an active ESG program and continued working in 2020 to improve upon our various ESG efforts.
For instance, we significantly increased the percentage of new production facilities operating on electrical grid power, 
lowering emissions by removing on-site generators. We also increased the percentage of recycled water used in 
our completions and increased the percentage of both produced water and oil we transported via pipeline.

Using batch drilling and longer laterals, we significantly increased our lateral footage drilled per new pad built,
helping to reduce our surface footprint. Finally, we continued our commitment to a proactive safety culture, with
approximately 2.1 million employee man-hours and no lost time accidents experienced from 2017 to 2020.

EXPLORATION AND PRODUCTION SEGMENT

Our current operations are focused primarily on the oil and liquids-rich portion of the Wolfcamp and Bone Spring

plays in the Delaware Basin in Southeast New Mexico and West Texas. We also operate in the Eagle Ford shale
play in South Texas and the Haynesville shale and Cotton Valley plays in Northwest Louisiana. During 2020, we 
devoted most of our efforts and most of our capital expenditures to our drilling and completion operations in the 
Wolfcamp and Bone Spring plays in the Delaware Basin, as well as our midstream operations there. Since our
inception, our exploration and development efforts have concentrated primarily on known hydrocarbon-producing
basins with well-established production histories offering the potential for multiple-zone completions.

Identified and engineered drilling locations. These locations have been identified for potential future drilling and were not producing at
December 31, 2020. The total net engineered drilling locations are calculated by multiplying the gross engineered drilling locations in an operating 
area by our working interest participation in such locations. Individual horizontal drilling locations generally represent a variety of lateral lengths, 
from one mile to greater than two miles, based upon our current assumptions for a well that could be drilled at that location given our current
acreage position. At December 31, 2020, approximately two-thirds of these identified drilling locations were expected to be horizontal laterals 
with lateral lengths of two miles or greater, and approximately 80% are expected to have lateral lengths of 1.5 miles or greater. At December 31, 
2020, these engineered drilling locations included only 358 gross (145 net) locations to which we have assigned proved undeveloped reserves, 
primarily in the Wolfcamp or Bone Spring plays, but also in the Brushy Canyon, Avalon and Delaware formations, in the Delaware Basin. 
At December 31, 2020, we had assigned no proved undeveloped reserves to our leasehold in the Eagle Ford shale or the Haynesville shale,
primarily as a result of the significantly lower oil and natural gas prices used to estimate proved reserves at December 31, 2020, which were
$36.04 per Bbl and $1.99 per MMBtu, respectively, as compared to prior periods.

(2) These estimates were prepared by our engineering staff and audited by Netherland, Sewell & Associates, Inc., independent reservoir engineers.

For additional information regarding our oil and natural gas reserves, see “—Estimated Proved Reserves” and Supplemental Oil and Natural Gas
Disclosures included in the unaudited supplementary information in this Annual Report, which is incorporated herein by reference.

(3) Production volumes and proved reserves reported in two streams: oil and natural gas, including both dry and liquids-rich natural gas. Estimated 

using a conversion ratio of one Bbl of oil per six Mcf of natural gas.

(4) Includes potential future engineered drilling locations in the Wolfcamp, Bone Spring, Brushy Canyon and Avalon plays on our acreage in the

Delaware Basin at December 31, 2020.

(5) Includes one well producing oil from the Austin Chalk formation in La Salle County, Texas and two wells producing small quantities of natural gas 

from the San Miguel formation in Zavala County, Texas.

(6) Includes the Cotton Valley formation and shallower zones and also includes one well producing from the Frio formation in Orange County, Texas.

(7) Some of the same leases cover the net acres shown for both the Haynesville formation and the shallower Cotton Valley formation. Therefore,

the sum of the net acreage for both formations is not equal to the total net acreage for Northwest Louisiana. This total includes acreage that we 
are producing from or that we believe to be prospective for these formations.

We are active both as an operator and as a non-operating co-working interest owner with various industry 
participants. At December 31, 2020, we operated a significant majority of our acreage in the Delaware Basin in
Southeast New Mexico and West Texas. In those wells where we are not the operator, our working interests 
are often relatively small. At December 31, 2020, we also were the operator for approximately 93% of our Eagle Ford
acreage and approximately 52% of our Haynesville acreage, including approximately 8% of our acreage in what we
believe is the core area of the Haynesville play.

While we do not always have direct access to our operating partners’ drilling plans with respect to future well
locations on non-operated properties, we do attempt to maintain ongoing communications with the technical staff
of these operators in an effort to understand their drilling plans for purposes of our capital expenditure budget
and our booking of any related proved undeveloped well locations and reserves. We review these locations with 
Netherland, Sewell & Associates, Inc., independent reservoir engineers, on a periodic basis to ensure their
concurrence with our estimates of these drilling plans and our approach to booking these reserves.

Southeast New Mexico and West Texas — Delaware Basin

The greater Permian Basin in Southeast New Mexico and West Texas is a mature exploration and production 
region with extensive developments in a wide variety of petroleum systems resulting in stacked target horizons in
many areas. Historically, the majority of development in this basin has focused on relatively conventional reservoir
targets, but the combination of advanced formation evaluation, 3-D seismic technology, horizontal drilling and 
hydraulic fracturing technology is enhancing the development potential of this basin, particularly in the organic rich 
shales, or source rocks, of the Wolfcamp formation and in the low permeability sand and carbonate reservoirs of
the Bone Spring, Avalon and Delaware formations.

In the western part of the Permian Basin, also known as the Delaware Basin, the Lower Permian age Bone Spring 

(also called the Leonardian) and Wolfcamp formations are several thousand feet thick and contain stacked layers
of shales, sandstones, limestones and dolomites. These intervals represent a complex and dynamic submarine 
depositional system that also includes organic rich shales that are the source rocks for oil and natural gas produced
in the basin. Historically, production has come from conventional reservoirs; however, we and other industry players
have realized that the source rocks also have sufficient porosity and permeability to be commercial reservoirs.
In addition, the source rocks are interbedded with reservoir layers that have filled with hydrocarbons, both of which
can produce significant volumes of oil and natural gas when connected by horizontal wellbores with multi-stage
hydraulic fracture treatments. Particularly in the Delaware Basin, there are multiple horizontal targets in a given area 
that exist within the several thousand feet of hydrocarbon bearing layers that make up the Bone Spring and 
Wolfcamp plays. Multiple horizontal drilling and completion targets are being identified and targeted by companies, 
including us, throughout the vertical section, including the Brushy Canyon, Avalon, Bone Spring (First, Second
and Third Sand and Carbonate) and several intervals within the Wolfcamp shale, often identified as Wolfcamp A
through D.

MATADOR RESOURCES COMPANY 

At December 31, 2020, our total acreage position in Southeast New Mexico and West Texas was approximately

230,600 gross (124,700 net) acres, primarily in Loving County, Texas and Lea and Eddy Counties, New Mexico.
These acreage totals included approximately 34,600 gross (18,400 net) acres in our Ranger asset area in Lea County,
66,000 gross (26,800 net) acres in our Arrowhead asset area in Eddy County, 47,900 gross (26,200 net) acres in 
our Rustler Breaks asset area in Eddy County, 23,200 gross (16,000 net) acres in our Antelope Ridge asset area in 
Lea County, 15,100 gross (10,800 net) acres in our Wolf and Jackson Trust asset areas in Loving County, 2,800 gross 
(2,800 net) acres in our Stateline asset area in Eddy County and 40,500 gross (23,200 net) acres in our Twin Lakes
asset area in Lea County at December 31, 2020. We consider the vast majority of our Delaware Basin acreage 
position to be prospective for oil and liquids-rich targets in the Bone Spring and Wolfcamp formations. Other
potential targets on certain portions of our acreage include the Avalon and Delaware formations, as well as the Abo,
Strawn, Devonian, Penn Shale, Atoka and Morrow formations. At December 31, 2020, our acreage position in the
Delaware Basin was approximately 67% held by existing production. Excluding the Twin Lakes asset area, where 
we have drilled only three vertical operated wells and two horizontal operated wells, and the undeveloped acreage 
acquired in the Bureau of Land Management New Mexico Oil and Gas Lease Sale on September 5 and 6, 2018
(the “BLM Acquisition”), which has 10-year leases with favorable lease-holding provisions, our acreage position in
the Delaware Basin was approximately 79% held by existing production at December 31, 2020.

During the year ended December 31, 2020, we continued the delineation and development of our Delaware Basin

acreage. We completed and began producing oil and natural gas from 89 gross (47.8 net) wells in the Delaware 
Basin, including 53 gross (45.6 net) operated horizontal wells and 36 gross (2.2 net) non-operated horizontal wells,
throughout our various asset areas. At December 31, 2020, we had tested a number of different producing horizons
at various locations across our acreage position, including the Brushy Canyon, the Avalon, the First Bone Spring, 
two benches of the Second Bone Spring, two benches of the Third Bone Spring, three benches of the Wolfcamp A, 
including the X and Y sands and the more organic, lower section of the Wolfcamp A, three benches of the 
Wolfcamp B, the Wolfcamp D, the Morrow and the Strawn. Most of our delineation and development efforts have 
been focused on multiple completion targets between the First Bone Spring and the Wolfcamp B.

As a result of our ongoing drilling and completion operations in these asset areas, our Delaware Basin production 

increased significantly in 2020. Our average daily oil equivalent production from the Delaware Basin increased
approximately 21% to 67,522 BOE per day (90% of total oil equivalent production), including 41,678 Bbl of oil per
day (96% of total oil production) and 155.1 MMcf of natural gas per day (82% of total natural gas production),
in 2020, as compared to 55,599 BOE per day (84% of total oil equivalent production), including 35,184 Bbl of oil
per day (92% of total oil production) and 122.5 MMcf of natural gas per day (73% of total natural gas production),
in 2019. Our average daily oil equivalent production from the Delaware Basin also grew approximately 26% from 
61,493 BOE per day in the fourth quarter of 2019 to 77,367 BOE per day in the fourth quarter of 2020.

At December 31, 2020, approximately 97% of our estimated total proved oil and natural gas reserves, or

261.9 million BOE, was attributable to the Delaware Basin, including approximately 156.3 million Bbl of oil and 
633.5 Bcf of natural gas, a 12% increase, as compared to 232.8 million BOE for the year ended December 31, 2019.
Our Delaware Basin proved reserves at December 31, 2020 comprised approximately 98% of our proved oil reserves 
and 96% of our proved natural gas reserves, as compared to approximately 94% of our proved oil reserves and 89% 
of our proved natural gas reserves at December 31, 2019.

2020 ANNUAL REPORT

At December 31, 2020, we had identified 4,359 gross (1,502 net) engineered locations for potential future drilling

on our Delaware Basin acreage, primarily in the Wolfcamp or Bone Spring plays, but also including the shallower 
Brushy Canyon and Avalon formations. These locations include 2,091 gross (1,298 net) locations that we anticipate
operating as we hold a working interest of at least 25% in each of these locations. Individual horizontal drilling
locations represent a variety of lateral lengths, from one mile to greater than two miles based upon our current
assumptions for a well that could be drilled at that location given our current acreage position. At December 31, 2020, 
approximately two-thirds of these identified drilling locations are expected to have horizontal lateral lengths of two 
miles or greater and approximately 80% are expected to have horizontal lateral lengths greater than 1.5 miles. At 
and prior to December 31, 2019, all of our identified horizontal drilling locations were based on the assumptions of 
a one-mile lateral being drilled at each location. These engineered locations have been identified on a property-by-
property basis and take into account criteria such as anticipated geologic conditions and reservoir properties,
estimated rates of return, estimated recoveries from our Delaware Basin wells and other nearby wells based on
available public data, drilling densities anticipated on our properties and properties of other operators, estimated 
drilling and completion costs, spacing and other rules established by regulatory authorities and surface considerations, 
among other criteria. Our engineered well locations at December 31, 2020 do not yet include all portions of our
acreage position. Our identified well locations presume that multiple intervals may be prospective at any one surface
location. Although we believe that denser well spacing may be possible in certain asset areas or in certain formations, at 
December 31, 2020, the majority of our estimated locations were based on the assumption of 160-acre well spacing. 
As we explore and develop our Delaware Basin acreage further, we anticipate that we may identify additional locations
for future drilling. At December 31, 2020, these potential future drilling locations included 358 gross (145 net) 
locations in the Delaware Basin, primarily in the Wolfcamp and Bone Spring plays, but also in the Brushy Canyon,
Avalon and Delaware formations, to which we have assigned proved undeveloped reserves.

At December 31, 2020, we were operating three drilling rigs in the Delaware Basin, and we expect to operate
three rigs in the Delaware Basin during most of the first quarter of 2021. We expect to add a fourth rig in March 2021
and to operate four rigs in the Delaware Basin throughout the remainder of 2021. Two of these operated rigs are 
expected to operate full-time in the Stateline asset area. The other two rigs are expected to operate in certain of our 
other asset areas, including the Greater Stebbins Area, the Wolf asset area, the Ranger asset area and the Rodney 
Robinson leasehold in the western portion of the Antelope Ridge asset area. We have built significant optionality into 
our drilling program, which allowed us to decrease the number of rigs in 2020 from six to three within a few 
months and should generally allow us to increase or decrease the number of rigs we operate as necessary based
on changing commodity prices and other factors. We are also planning to participate in non-operated wells in the 
Delaware Basin as these opportunities arise in 2021.

Antelope Ridge Asset Area - Lea County, New Mexico

At the end of the first quarter of 2020, we achieved the first of the five operational milestones we set for 

Matador in 2020 when we completed and turned to sales our first six gross (6.0 net) wells on the Rodney Robinson 
leasehold. These wells also were the first wells drilled on acreage acquired in the BLM Acquisition. Including the
Rodney Robinson wells, we completed and turned to sales 12 gross (11.4 net) operated and 15 gross (0.3 net) 
non-operated wells in the Antelope Ridge asset area during 2020.

The 1,200 gross and net acre Rodney Robinson leasehold is one of the key tracts we acquired as part of the of

8,400 gross and net leasehold acres in Lea and Eddy Counties, New Mexico for approximately $387 million in the 
BLM Acquisition. The federal leases provide an 87.5% net revenue interest (“NRI”) as compared to approximately
75% NRI on most fee leases today. The six Rodney Robinson wells, which included two Wolfcamp A-XY
completions, two Second Bone Spring completions, one Upper Avalon completion and one Lower Avalon completion, 
were turned to sales late in the first quarter of 2020 and were all two-mile laterals. The 24-hour initial potential (“IP”) 

  FORM 10-K PART I

MATADOR RESOURCES COMPANY 

test results from all six Rodney Robinson wells totaled 19,236 BOE per day (79% oil). Notably, these IP test results
included, at the time, the best IP test results we had achieved for wells completed and turned to sales in the Avalon, 
Second Bone Spring and Wolfcamp A-XY formations throughout the Delaware Basin. These six Rodney Robinson
wells have produced in aggregate approximately 2.7 million BOE in approximately 10 months of production. We
drilled four additional Rodney Robinson wells in the fall of 2020, and these four wells are expected to be completed 
and turned to sales late in the first quarter of 2021.

Rustler Breaks Asset Area - Eddy County, New Mexico

In the Rustler Breaks asset area, we completed and turned to sales 13 gross (7.8 net) operated wells and 21 gross

(1.9 net) non-operated wells during 2020.

During the second quarter of 2020, we achieved the second of the five operational milestones we set for

Matador in 2020 when we completed and turned to sales five wells on our Ray State leasehold in the eastern portion 
of the Rustler Breaks asset area in late May and early June. These five wells, which were all-two mile laterals, included
two Wolfcamp A-XY completions, one Wolfcamp A-Lower completion and two Wolfcamp B-Blair completions. The
24-hour IP aggregate test results for the five Ray State wells were 12,507 BOE per day (61% oil). These five Ray State 
wells have produced in aggregate approximately 1.6 million BOE in just over seven months of production.

During the fourth quarter of 2020, we completed and turned to sales three wells on our Ace Stern Vegas
leasehold in northeast Rustler Breaks, including two Wolfcamp A-XY completions and one Third Bone Spring 
completion. The 24-hour IP aggregate test results for these three wells, which were all two-mile laterals, were 
7,415 BOE per day (74% oil). We believe these three wells demonstrate the prospectivity of the northeastern
portion of our Rustler Breaks acreage.

Arrowhead, Ranger and Twin Lakes Asset Areas - Eddy and Lea Counties, New Mexico

During the third quarter of 2020, we achieved the third of the five operational milestones we set for Matador

in 2020 when we completed and turned to sales five gross (4.3 net) operated wells, all of which were two-mile
laterals, on the Leatherneck tract in the Greater Stebbins Area. These five Leatherneck wells have produced
in aggregate approximately 1.0 million BOE in just over six months of production. We did not complete or turn 
to sales any other operated or non-operated wells in other portions of the Arrowhead asset area or in the Ranger 
or Twin Lakes asset areas during 2020.

We were pleased with the performance from the five Leatherneck wells, which included two Third Bone Spring 

completions, two Wolfcamp A-XY completions and one Wolfcamp B completion. The Wolfcamp B completion 
was particularly noteworthy, being our first test of the Wolfcamp B formation this far north in the Delaware Basin. 
This Wolfcamp B completion tested 2,101 BOE per day (71% oil) during its 24-hour IP test. We believe these
results provide evidence of Wolfcamp B prospectivity moving north in the Delaware Basin.

Stateline Asset Area - Eddy County, New Mexico

We operated two drilling rigs in our Stateline asset area for the majority of 2020 and expect to do so again in 

2021. In early September 2018, we acquired the Stateline asset area in southern Eddy County, New Mexico as
part of the BLM Acquisition. The Stateline asset area includes approximately 2,800 gross and net leasehold acres
prospective for multiple geologic targets. The federal leases provide an 87.5% NRI. The large majority of the 
Stateline asset area acreage is believed to be conducive to drilling longer laterals of up to two miles or more, utilizing 
central facilities and multi-well pad development. We plan to develop this acreage block drilling two-mile laterals 

FORM 10-K PART I

2020 ANNUAL REPORT

on the eastern side of the leasehold and approximately 2.5-mile laterals on the western side of the leasehold. 
We began drilling operations in the Stateline asset area just before the end of 2019 and, at the end of the third
quarter of 2020, we achieved the last two of the five operational milestones we set for Matador in 2020 when 
we completed and turned to sales our first 13 gross (13.0 net) wells on the Boros tract in the eastern portion of the 
Stateline asset area and connected these wells to the expanded Black River Processing Plant and associated 
pipeline and facilities discussed below.

The 13 Boros wells, all of which were two-mile laterals, tested six different intervals and included one Avalon

completion, two Second Bone Spring completions, four Wolfcamp A-XY completions, four Wolfcamp A-Lower
completions, one Wolfcamp B-Upper completion and one Wolfcamp B-Lower completion. In aggregate, these 13 Boros 
wells tested 45,225 BOE per day (56% oil), and the IP test results from the two Second Bone Spring completions
were the top two IP test results that we had reported to date for wells completed and turned to sales in that
formation throughout the Delaware Basin. Similarly, the IP test results for three of the Wolfcamp A-Lower completions 
were three of the top four IP test results that we had achieved to date for wells completed and turned to sales 
in the Wolfcamp A-Lower formation. In addition, most of these 24-hour IP test results were recorded at high flowing 
casing pressures of between 3,000 and 4,200 pounds per square inch (“psi”) in the Wolfcamp A-XY, Wolfcamp
A-Lower and Wolfcamp B formations, further indicating the potential of these wells. These 13 Boros wells have 
produced in aggregate approximately 2.7 million BOE in just over four months of production, despite a number of 
these wells being produced on restricted chokes early in their production.

In addition, during 2020, we drilled 13 wells on the Voni tract on the western portion of the Stateline leasehold. 

These 13 Voni wells are expected to have completed lateral lengths of approximately 12,000 feet and should be 
completed in the first quarter of 2021 and turned to sales early in the second quarter of 2021.

Wolf and Jackson Trust Asset Areas - Loving County, Texas

In the Wolf and Jackson Trust asset areas, we completed and turned to sales 10 gross (9.1 net) operated wells

during 2020. The Larson 04-TTT-B02 WF #136H (Larson #136H) well in the Wolf asset area was particularly
significant, being our first test of the Third Bone Spring Carbonate formation in the Delaware Basin. The Larson #136H 
well tested 1,668 BOE per day (68% oil) from a completed lateral length of 7,443 feet. We believe this test result
indicates the prospectivity of the Third Bone Spring Carbonate, not only in the Wolf asset area, but also in our other
asset areas throughout the Delaware Basin.

South Texas — Eagle Ford Shale and Other Formations

The Eagle Ford shale extends across portions of South Texas from the Mexican border into East Texas forming 
a band roughly 50 to 100 miles wide and 400 miles long. The Eagle Ford is an organically rich calcareous shale and 
lies between the deeper Buda limestone and the shallower Austin Chalk formation. Along the entire length of the 
Eagle Ford trend, the structural dip of the formation is consistently down to the south with relatively few, modestly
sized structural perturbations. As a result, depth of burial increases consistently southwards along with the thermal 
maturity of the formation. Where the Eagle Ford is shallow, it is less thermally mature and therefore more oil prone,
and as it gets deeper and becomes more thermally mature, the Eagle Ford is more natural gas prone. The transition 
between being more oil prone and more natural gas prone includes an interval that typically produces liquids-rich 
natural gas with condensate.

   FORM 10-K PART I

 
 
14

MATADOR RESOURCES COMPANY 

At December 31, 2020, our properties included approximately 29,300 gross (26,300 net) acres in the Eagle Ford
shale play in South Texas. We believe that approximately 87% of our Eagle Ford acreage is prospective predominantly 
for oil or liquids-rich natural gas with condensate, with the remainder being prospective for less liquids-rich natural
gas. Approximately 99% of our Eagle Ford acreage was held by production at December 31, 2020.

We did not conduct any operated or non-operated drilling and completion activities on our leasehold properties in 

South Texas during the year ended December 31, 2020. In fact, as of December 31, 2020, we had not completed
any wells in the Eagle Ford shale in over 18 months. As a result, our average daily oil equivalent production from the
Eagle Ford shale decreased 40% to 2,412 BOE per day, including 1,840 Bbl of oil per day and 3.4 MMcf of natural 
gas per day, during 2020, as compared to 4,009 BOE per day, including 3,113 Bbl of oil per day and 5.4 MMcf of
natural gas per day, during 2019. For the year ended December 31, 2020, 3% of our total daily oil equivalent production
was attributable to the Eagle Ford shale, as compared to 6% for the year ended December 31, 2019.

At December 31, 2020, approximately 2% of our estimated total proved oil and natural gas reserves, or 4.9 million 

BOE, was attributable to the Eagle Ford shale, including approximately 3.6 million Bbl of oil and 7.8 Bcf of natural 
gas. Our Eagle Ford total proved reserves comprised approximately 2% of our proved oil reserves and 1% of our
proved natural gas reserves at December 31, 2020, as compared to approximately 6% of our proved oil reserves
and 3% of our proved natural gas reserves at December 31, 2019.

At December 31, 2020, we had identified 229 gross (182 net) engineered locations for potential future drilling on
our Eagle Ford acreage. Each drilling location represents a horizontal lateral, and individual locations have estimated 
lateral lengths ranging from one mile to almost two miles. These locations have been identified on a property-by-
property basis and take into account criteria such as anticipated geologic conditions and reservoir properties,
estimated rates of return, estimated recoveries from our producing Eagle Ford wells and other nearby wells based
on available public data, drilling densities anticipated on our properties and observed on properties of other operators, 
estimated drilling and completion costs, spacing and other rules established by regulatory authorities and surface 
considerations, among other factors.

These engineered drilling locations include only a single interval in the lower portion of the Eagle Ford shale. 
We believe portions of our Eagle Ford acreage may be prospective for an additional target in the lower portion of 
the Eagle Ford shale and for other intervals in the upper portion of the Eagle Ford shale, from which we would
expect to produce predominantly oil and liquids. In addition, we believe portions of our South Texas acreage may 
also be prospective for the Austin Chalk, Buda and other formations, from which we would expect to produce
predominantly oil and liquids. At December 31, 2020, we had not included any future drilling locations in the upper 
portion of the Eagle Ford shale, in any additional intervals of the lower portion of the Eagle Ford shale or in
the Austin Chalk or Buda formations, even though activity from other operators in these formations around our 
South Texas acreage position has demonstrated the prospectivity of these intervals.

Northwest Louisiana — Haynesville Shale, Cotton Valley and Other Formations

The Haynesville shale is an organically rich, overpressured marine shale found below the Cotton Valley and

Bossier formations and above the Smackover formation at depths ranging from 10,500 to 13,500 feet across
a broad region throughout Northwest Louisiana, including principally Bossier, Caddo, DeSoto and Red River Parishes 
in Louisiana. The Haynesville shale produces primarily dry natural gas with almost no associated liquids. The 
Bossier shale is overpressured and is often divided into lower, middle and upper units. The Cotton Valley formation
is a low permeability natural gas sand that ranges in thickness from 200 to 300 feet and has porosity ranging from 
6% to 10%.

We did not conduct any operated drilling and completion activities on our leasehold properties in Northwest
Louisiana during 2020, although we did participate in the drilling and completion of four gross (less than 0.1 net) 
non-operated Haynesville shale wells that were turned to sales in 2020. In the first quarter of 2020, we leased
2,800 net acres of our minerals in the southern portion of our Pine Island asset area to a third party and retained 
royalty interests ranging from 18% to 20%. This lessee drilled four wells in the second half of 2020. We do not
plan to drill any operated Haynesville shale or Cotton Valley wells in 2021.

At December 31, 2020, we held approximately 19,100 gross (17,700 net) acres in Northwest Louisiana, including
16,700 gross (9,100 net) acres in the Haynesville shale play and 16,100 gross (14,900 net) acres in the Cotton Valley
play. We operate substantially all of our Cotton Valley and shallower production on our leasehold interests in
Northwest Louisiana, as well as all of our Haynesville production on the acreage outside of what we believe to be 
the core area of the Haynesville shale play. We operate approximately 8% of the 11,600 gross (4,800 net) acres
that we consider to be in the core area of the Haynesville shale play.

For the year ended December 31, 2020, approximately 7% of our average daily oil equivalent production, or 
5,241 BOE per day, including eight Bbl of oil per day and 31.4 MMcf of natural gas per day, was attributable to our 
leasehold interests in Northwest Louisiana, while for the year ended December 31, 2019, approximately 10%
of our average daily oil equivalent production, or 6,595 BOE per day, including 15 Bbl of oil per day and 39.5 MMcf
of natural gas per day, was attributable to our properties in Northwest Louisiana. For the year ended December 31, 
2020, approximately 17% of our daily natural gas production, or 31.4 MMcf of natural gas per day, was attributable
to our leasehold interests in Northwest Louisiana, while for the year ended December 31, 2019, approximately
24% of our daily natural gas production, or 39.5 MMcf of natural gas per day, was attributable to these properties. 
At December 31, 2020, just over 1% of our estimated total proved reserves, or 3.5 million BOE, was attributable
to our properties in Northwest Louisiana.

At December 31, 2020, we had identified 163 gross (16 net) engineered locations for potential future drilling in

the Haynesville shale play and 154 gross (35 net) engineered locations for potential future drilling in the Cotton 
Valley formation. Each drilling location represents a horizontal lateral, and individual locations have estimated lateral 
lengths ranging from one mile to two miles, with most being two miles. These locations have been identified
on a property-by-property basis and take into account criteria such as anticipated geologic conditions and reservoir
properties, estimated rates of return, estimated recoveries from our producing Haynesville and Cotton Valley wells
and other nearby wells based on available public data, drilling densities observed on properties of other operators,
including on some of our non-operated properties, estimated drilling and completion costs, spacing and other rules
established by regulatory authorities and surface conditions, among other factors.

MIDSTREAM SEGMENT

Our midstream segment conducts midstream operations in support of our exploration, development and

production operations and provides natural gas processing, oil transportation services, oil, natural gas and produced 
water gathering services and produced water disposal services to third parties.

Southeast New Mexico and West Texas — Delaware Basin

On February 17, 2017, we announced the formation of San Mateo I, a strategic joint venture with Five Point. The 

midstream assets that were contributed to San Mateo I included (i) the Black River Processing Plant (before its
expansions); (ii) one salt water disposal well and a related commercial salt water disposal facility in the Rustler Breaks 
asset area; (iii) three salt water disposal wells and related commercial salt water disposal facilities in the Wolf asset 
area and (iv) substantially all related oil, natural gas and produced water gathering systems and pipelines in both
the Rustler Breaks and Wolf asset areas (collectively, the “Delaware Midstream Assets”). We received $171.5 million 
in connection with the formation of San Mateo I and had the potential to earn up to $73.5 million in performance
incentives over a five-year period, which in October 2020 was extended by an additional year. At February 23, 2021, 
we had earned $58.8 million of the potential $73.5 million in performance incentives. Through February 23, 2021,
Five Point had paid $14.7 million in performance incentives in each of the first quarters of 2018, 2019 and 2020, 
and we expect Five Point to pay us an additional $14.7 million in performance incentives in the first quarter of 
2021. We may earn up to the remaining $14.7 million in San Mateo I performance incentives over the next two years. 
In connection with the formation of San Mateo I, we dedicated to San Mateo I current and certain future leasehold
interests in the Rustler Breaks and Wolf asset areas pursuant to 15-year, fixed fee oil, natural gas and produced water 
gathering and produced water disposal agreements. In addition, we dedicated current and certain future 
leasehold interests in the Rustler Breaks asset area to San Mateo I pursuant to a 15-year, fixed fee natural gas
processing agreement.

On February 25, 2019, we announced the formation of San Mateo II, a strategic joint venture with Five Point
designed to expand our midstream operations in the Delaware Basin, specifically in Eddy County, New Mexico. 
In addition, Five Point committed to pay $125.0 million of the first $150.0 million of capital expenditures incurred by
San Mateo II to develop facilities in the Greater Stebbins Area and the Stateline asset area. The $150.0 million 
threshold for capital expenditures was reached during 2020 and additional capital expenditures are the responsibility
of the Company and Five Point based on each company’s proportionate interest in San Mateo. In addition, we 
have the ability to earn up to $150.0 million in deferred performance incentives over the next several years, plus
additional performance incentives for securing volumes from third-party customers. During the fourth quarter of
2020, we met the threshold requirements to begin earning the additional $150.0 million in performance incentives 
from Five Point. At February 23, 2021, we had received $0.7 million of the potential $150.0 million in performance 
incentives. In connection with the formation of San Mateo II, we dedicated to San Mateo II acreage in the Greater
Stebbins Area and the Stateline asset area pursuant to 15-year, fixed-fee oil, natural gas and produced water 
gathering, natural gas processing and produced water disposal agreements.

Effective October 1, 2020, San Mateo II merged with and into San Mateo I. The Company and Five Point own
51% and 49% of San Mateo, respectively. San Mateo provides firm service to us, while also being a midstream 
service provider to other customers in and around our Stateline, Wolf and Rustler Breaks asset areas and the Greater 
Stebbins Area. We retain operational control of San Mateo and continue to operate the Delaware Midstream
Assets, the expanded Black River Processing Plant and facilities that have been developed in the Greater Stebbins
Area and the Stateline asset area.

Natural Gas Gathering and Processing Assets

The Black River Processing Plant and associated gathering system were originally built to support our ongoing 

and future development efforts in the Rustler Breaks asset area and to provide us with firm takeaway and 
processing services for our Rustler Breaks natural gas production. We had previously completed the installation and 
testing of a 12-inch natural gas trunk line and associated gathering lines running throughout the length of 
our Rustler Breaks acreage position, and these natural gas gathering lines are being used to gather almost all 
of our operated natural gas production at Rustler Breaks.

During the third quarter of 2020, San Mateo completed the construction and successful start-up of the expansion

of the Black River Processing Plant to add an incremental designed inlet capacity of 200 MMcf of natural gas
per day to the existing designed inlet capacity of 260 MMcf of natural gas per day, bringing the total designed inlet 
capacity to 460 MMcf of natural gas per day. The expanded Black River Processing Plant supports our exploration 
and development activities in the Delaware Basin and, at December 31, 2020, was gathering and processing 
natural gas from the Stateline asset area and from the Greater Stebbins Area. The Black River Processing Plant
also processes natural gas from our Rustler Breaks asset area and provides natural gas processing services for
other San Mateo customers in the area.

In September 2020, San Mateo completed and placed in service approximately 43 miles of large diameter natural

gas gathering pipelines between the Black River Processing Plant and the Stateline asset area (approximately
24 miles) and the Greater Stebbins Area (approximately 19 miles). At December 31, 2020, San Mateo was gathering
or transporting all our operated natural gas production via pipeline in the Stateline asset area, the Greater Stebbins 
Area, the Rustler Breaks asset area and the Wolf asset area.

In addition, in early 2018, San Mateo completed a natural gas liquids (“NGL”) pipeline connection at the Black River

Processing Plant to the NGL pipeline owned by EPIC Y-Grade Pipeline LP. This NGL connection provides several 
significant benefits to us and other San Mateo customers compared to transporting the NGLs by truck. San Mateo’s 
customers receive (i) firm NGL takeaway out of the Delaware Basin, (ii) increased NGL recoveries, (iii) improved
pricing realizations through lower transportation and fractionation costs, (iv) increased optionality through San Mateo’s
ability to operate the Black River Processing Plant in ethane recovery mode, if desired, and (v) a reliable alternative
to pipe rather than to truck NGLs during severe weather events and otherwise.

In our Wolf asset area in Loving County, Texas, San Mateo gathers our natural gas production with the natural
gas gathering system we retained following the sale of our wholly-owned subsidiary that owned certain natural gas 
gathering and processing assets in the Wolf asset area, including a cryogenic natural gas processing plant (the 
“Wolf Processing Plant”) and approximately six miles of high-pressure gathering pipeline.

At December 31, 2020, San Mateo’s natural gas gathering systems included natural gas gathering pipelines and

related compression and treating systems. During the year ended December 31, 2020, San Mateo gathered 
approximately 73.9 Bcf of natural gas, a decrease of 4%, as compared to 77.2 Bcf of natural gas gathered during 
the year ended December 31, 2019. In addition, during the year ended December 31, 2020, San Mateo processed 
approximately 60.8 Bcf of natural gas at the Black River Processing Plant, a decrease of 6%, as compared to
64.7 Bcf of natural gas processed during the year ended December 31, 2019. San Mateo’s natural gas gathering
and processing volumes declined slightly in 2020 as compared to 2019 due to reduced volumes from a significant
third-party customer, but San Mateo’s sequential natural gas gathering and processing volumes increased 
significantly in the fourth quarter of 2020, as compared to the third quarter of 2020, as we realized the first 
full quarter of production from the Boros wells in the Stateline asset area and the Leatherneck wells in the Greater 
Stebbins Area.

Crude Oil Gathering and Transportation Assets

San Mateo and Plains have entered into a strategic relationship to gather and transport crude oil for upstream

producers in Eddy County, New Mexico and have agreed to work together through a joint tariff arrangement and 
related transactions to offer producers located within the Joint Development Area crude oil transportation services 
from the wellhead to Midland, Texas with access to other end markets.

In 2020, San Mateo completed and placed into service (i) a crude oil gathering and transportation system in the 

Greater Stebbins Area, which was connected to the existing interconnect in the Rustler Breaks asset area via 
approximately 19 miles of various diameter crude oil pipelines and (ii) a crude oil gathering system in the Stateline 
asset area. With these oil gathering and transportation systems (collectively with the crude oil gathering and 
transportation system in the Rustler Breaks asset area and the crude oil gathering system in the Wolf asset area, 
the “San Mateo Oil Pipeline Systems”) in service, at December 31, 2020, we estimated we had on pipe almost
all of our oil production from the Stateline, Wolf and Rustler Breaks asset areas and the Greater Stebbins Area.

At December 31, 2020, the San Mateo Oil Pipeline Systems included crude oil gathering and transportation
pipelines from points of origin in Loving County, Texas and Eddy County, New Mexico to interconnects with Plains 
and two trucking facilities. During the year ended December 31, 2020, the San Mateo Oil Pipeline Systems had
throughput of approximately 11.6 million Bbl of oil, an increase of 32%, as compared to throughput of approximately 
8.9 million Bbl of oil during the year ended December 31, 2019.

Produced Water Gathering and Disposal Assets

During 2020, San Mateo placed into service one commercial salt water disposal well in the Rustler Breaks asset 

area, bringing San Mateo’s commercial salt water disposal well count in the Rustler Breaks asset area to eight.
In addition to its eight commercial salt water disposal wells and associated facilities in the Rustler Breaks asset area, 
at February 23, 2021, San Mateo had three commercial salt water disposal wells and associated facilities in the
Wolf asset area, two commercial salt water disposal wells and associated facilities in the Greater Stebbins Area and 
produced water gathering systems in the Stateline, Rustler Breaks and Wolf asset areas and the Greater Stebbins 
Area. At February 23, 2021, San Mateo had designed disposal capacity of approximately 335,000 Bbl of produced
water per day.

During the year ended December 31, 2020, San Mateo handled approximately 84.8 million Bbl of produced
water, an increase of 15%, as compared to approximately 73.9 million Bbl of produced water handled during the 
year ended December 31, 2019.

South Texas / Northwest Louisiana

In South Texas, we own a natural gas gathering system that gathers natural gas production from certain of our
operated Eagle Ford leases. In Northwest Louisiana, we have midstream assets that gather natural gas from most 
of our operated leases and from third parties. Our midstream assets in South Texas and Northwest Louisiana are 
not part of San Mateo.

Our total oil equivalent production of approximately 27.5 million BOE for the year ended December 31, 2020

increased 14% from our total oil equivalent production of approximately 24.2 million BOE for the year ended 
December 31, 2019. This increased production was primarily due to our delineation and development operations in 
the Delaware Basin throughout 2020, which offset declining production in the Eagle Ford and Haynesville shales.
Our average daily oil equivalent production for the year ended December 31, 2020 was 75,175 BOE per day, as 
compared to 66,203 BOE per day for the year ended December 31, 2019. Our average daily oil production for the
year ended December 31, 2020 was 43,526 Bbl of oil per day, an increase of 14% from 38,312 Bbl of oil per day 
for the year ended December 31, 2019. Our average daily natural gas production for the year ended December 31,
2020 was 189.9 MMcf of natural gas per day, an increase of 13% from 167.4 MMcf of natural gas per day for the 
year ended December 31, 2019.

Our total oil equivalent production of approximately 24.2 million BOE for the year ended December 31, 2019

increased 27% from our total oil equivalent production of approximately 19.0 million BOE for the year ended 
December 31, 2018. This increased production was primarily due to our delineation and development operations in 
the Delaware Basin throughout 2019 as well as from our nine-well program in South Texas concluded in the first 
half of 2019 and non-operated Haynesville shale wells completed and placed on production during the third quarter
of 2019. Our average daily oil equivalent production for the year ended December 31, 2019 was 66,203 BOE per 
day, as compared to 52,128 BOE per day for the year ended December 31, 2018. Our average daily oil production

ESTIMATED PROVED RESERVES

The following table sets forth our estimated proved oil and natural gas reserves at December 31, 2020, 2019 and

2018. Our production and proved reserves are reported in two streams: oil and natural gas, including both dry and 
liquids-rich natural gas. Where we produce liquids-rich natural gas, such as in the Delaware Basin and the Eagle Ford
shale, the economic value of the NGLs associated with the natural gas is included in the estimated wellhead natural
gas price on those properties where the NGLs are extracted and sold. The reserves estimates were based on 
evaluations prepared by our engineering staff and have been audited for their reasonableness by Netherland, Sewell
& Associates, Inc., independent reservoir engineers. These reserves estimates were prepared in accordance with 
SEC rules for oil and natural gas reserves reporting. The estimated reserves shown are for proved reserves only and
do not include any unproved reserves classified as probable or possible reserves that might exist for our properties, 
nor do they include any consideration that could be attributable to interests in unproved and unevaluated acreage 
beyond those tracts for which proved reserves have been estimated. Proved oil and natural gas reserves are the
estimated quantities of crude oil and natural gas that geological and engineering data demonstrate with reasonable 
certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions.

(2) Our 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 12 months ended December 31, 2020 were $36.04 per Bbl for oil and $1.99 per MMBtu for natural gas, 
for the 12 months ended December 31, 2019 were $52.19 per Bbl for oil and $2.58 per MMBtu for natural gas and for the 12 months ended 
December 31, 2018 were $62.04 per Bbl for oil and $3.10 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. 
We report our proved reserves in two streams, oil and natural gas, and the economic value of the NGLs associated with the natural gas is
included in the estimated wellhead natural gas price on those properties where the NGLs are extracted and sold.

(3) Estimated using a conversion ratio of one Bbl of oil per six Mcf of natural gas.

(4) Standardized Measure represents the present value of estimated future net cash flows from proved reserves, less estimated future 

development, production, plugging and abandonment and income tax expenses, discounted at 10% per annum to reflect the timing of future
cash flows. Standardized Measure is not an estimate of the fair market value of our properties.

(5) 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 our
properties. We 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.
Our PV-10 at December 31, 2020, 2019 and 2018 may be reconciled to our 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. The discounted future income
taxes at December 31, 2020, 2019 and 2018 were, in millions, $73.6, $214.2 and $328.7, respectively.

Our estimated total proved oil and natural gas reserves increased 7% from 252.5 million BOE at December 31,
2019 to 270.3 million BOE at December 31, 2020. This increase in proved oil and natural gas reserves was primarily 
a result of our delineation and development operations in the Delaware Basin during 2020. This increase in total
proved reserves was achieved despite (i) the reduction in our operated rig count from six to three during 2020 and
(ii) the 31% reduction in oil price and the 23% reduction in natural gas price used to estimate total proved reserves 
at December 31, 2020, as compared to December 31, 2019. We added 35.3 million BOE in proved oil and
natural gas reserves through extensions and discoveries throughout 2020, approximately 1.3 times our 2020 annual 
production of 27.5 million BOE. We also realized approximately 9.8 million BOE in net upward revisions to our
proved reserves during 2020, primarily as a result of upward revisions resulting from better-than-projected well 
performance from certain wells, as compared to December 31, 2019, which more than offset the downward 
revisions resulting from the significantly lower commodity prices used to estimate proved reserves at December 31, 
2020. Our proved oil reserves grew 8% from approximately 148.0 million Bbl at December 31, 2019 to 
approximately 159.9 million Bbl at December 31, 2020. Our proved natural gas reserves increased 6% from 627.2 Bcf
at December 31, 2019 to 662.3 Bcf at December 31, 2020. Our proved reserves to production ratio at December 31,
2020 was 9.8, a decrease of 7% from 10.5 at December 31, 2019.

MATADOR RESOURCES COMPANY 

Over the past two years, our estimated total proved oil and natural gas reserves increased 26% from
215.3 million BOE at December 31, 2018 to 270.3 million Bbl at December 31, 2020. Our proved oil reserves
grew 30% from 123.4 million Bbl at December 31, 2018 to 159.9 million Bbl at December 31, 2020. Our
proved developed oil reserves increased 31% from 53.2 million Bbl at December 31, 2018 to 69.6 million Bbl
at December 31, 2020.

The Standardized Measure of our total proved oil and natural gas reserves decreased 22% from $2.03 billion at 

December 31, 2019 to $1.58 billion at December 31, 2020. The PV-10 of our total proved oil and natural gas
reserves decreased 26% from $2.25 billion at December 31, 2019 to $1.66 billion at December 31, 2020. The
decreases in our Standardized Measure and PV-10 are primarily a result of the significantly lower weighted average 
oil and natural gas prices used to estimate proved reserves at December 31, 2020, as compared to December 31, 
2019. The unweighted arithmetic averages of first-day-of-the-month oil and natural gas prices used to estimate
proved reserves at December 31, 2020 were $36.04 per Bbl and $1.99 per MMBtu, a decrease of 31% and 23%, 
respectively, as compared to average oil and natural gas prices of $52.19 per Bbl and $2.58 per MMBtu used
to estimate proved reserves at December 31, 2019. Our total proved reserves were made up of 59% oil and
41% natural gas at both December 31, 2020 and December 31, 2019. PV-10 is a non-GAAP financial measure. 
For a reconciliation of PV-10 to Standardized Measure, see the preceding table.

Our proved developed oil and natural gas reserves increased 17% from 105.7 million BOE at December 31, 2019 

to 123.5 million BOE at December 31, 2020 due primarily to our delineation and development operations in the
Delaware Basin. Our proved developed oil reserves increased 17% from 59.7 million Bbl at December 31, 2019 to
69.6 million Bbl at December 31, 2020. Our proved developed natural gas reserves increased 17% from 276.3 Bcf
at December 31, 2019 to 323.2 Bcf at December 31, 2020.

Our proved undeveloped oil and natural gas reserves were 146.8 million BOE at both December 31, 2019 and 

December 31, 2020, as the net additions to our proved undeveloped reserves of 28.9 million BOE offset the 
28.9 million BOE we converted from proved undeveloped to proved developed reserves during 2020. Our proved
undeveloped oil reserves increased 2% from 88.3 million Bbl at December 31, 2019 to 90.3 million Bbl at 
December 31, 2020. Our proved undeveloped natural gas reserves decreased 3% from 351.0 Bcf at December 31, 
2019 to 339.1 Bcf at December 31, 2020. These changes in proved undeveloped oil and natural gas reserves 
were primarily the result of net increases in proved undeveloped reserves in the Delaware Basin resulting from our 
delineation and development operations there, which were offset by the conversion of proved undeveloped 
reserves to proved developed reserves and the removal of certain proved undeveloped reserves from total proved
reserves at December 31, 2020, primarily as a result of the significantly lower weighted average oil and natural
gas prices used to estimate proved reserves at December 31, 2020, as compared to December 31, 2019.

At December 31, 2020, we had no proved undeveloped reserves in our estimates that remained undeveloped

for five years or more following their initial booking, and we currently have plans to use anticipated capital 
resources to develop the proved undeveloped reserves remaining as of December 31, 2020 within five years of

Technology Used to Establish Reserves

Under current SEC rules, proved reserves are those quantities of oil and natural gas that, by analysis of geoscience 

and engineering data, can be estimated with reasonable certainty to be economically producible from a given 
date forward, from known reservoirs and under existing economic conditions, operating methods and government
regulations. The term “reasonable certainty” implies a high degree of confidence that the quantities of oil and/or 
natural gas actually recovered will equal or exceed the estimate. Reasonable certainty can be established using
techniques that have been proven effective by actual production from projects in the same reservoir or an analogous 
reservoir or by other evidence using reliable technology that establishes reasonable certainty. Reliable technology
is a grouping of one or more technologies (including computational methods) that have been field tested and have
been demonstrated to provide reasonably certain results with consistency and repeatability in the formation being
evaluated or in an analogous formation.

In order to establish reasonable certainty with respect to our estimated proved reserves, we used technologies 
that have been demonstrated to yield results with consistency and repeatability. The technologies and technical data 
used in the estimation of our proved reserves include, but are not limited to, electric logs, radioactivity logs, core 
analyses, geologic maps and available pressure and production data, seismic data and well test data. Reserves for
proved developed producing wells were estimated using production performance and material balance methods.
Certain new producing properties with little production history were forecasted using a combination of production
performance and analogy to offset production. Non-producing reserves estimates for both developed and 
undeveloped properties were forecasted using either volumetric and/or analogy methods.

Internal Control Over Reserves Estimation Process

We maintain an internal staff of petroleum engineers and geoscience professionals to ensure the integrity,

accuracy and timeliness of the data used in our reserves estimation process. For 2020, our Executive Vice President
of Reservoir Engineering and Chief Technology Officer was primarily responsible for overseeing the preparation
of our reserves estimates. He received his Bachelor and Master of Science degrees in Petroleum Engineering from 
Texas A&M University, is a Licensed Professional Engineer in the State of Texas and has over 43 years of industry
experience. Following the preparation of our reserves estimates, these estimates are audited for their reasonableness 
by Netherland, Sewell & Associates, Inc., independent reservoir engineers. The Operations and Engineering
Committee of our Board of Directors reviews the reserves report and our reserves estimation process, and the
results of the reserves report and the independent audit of our reserves are reviewed by other members of our
Board of Directors as well.

(1) Approximately 47% of the acreage expiring in the Delaware Basin in the next five years is associated with our Twin Lakes asset area in northern 
Lea County, New Mexico. We expect to hold or extend portions of certain expiring acreage in the Delaware Basin through our 2021 drilling
activities or by paying an additional lease bonus, where applicable.

Many of the leases comprising the acreage set forth in the table above will expire at the end of their respective

primary terms unless operations are conducted to maintain the respective leases in effect beyond the expiration 
of the primary term or production from the acreage has been established prior to such date, in which event the lease 
will remain in effect until the cessation of production in commercial quantities in most cases. We also have options 
to extend some of our leases through additional lease bonus payments prior to the expiration of the primary term of 
the leases. In addition, we may attempt to secure a new lease upon the expiration of certain of our acreage;
however, there may be third-party leases, or top leases, that become effective immediately if our leases expire at 
the end of their respective terms and production has not been established prior to such date or operations are
not conducted to maintain the leases in effect beyond the primary term. As of December 31, 2020, our leases are
primarily fee and state leases with primary terms of three to five years and federal leases with primary terms of 
10 years. We believe that our lease terms are similar to our competitors’ lease terms as they relate to both primary 
term and royalty interests.

MARKETING AND CUSTOMERS

Our crude oil is sold under both long-term and short-term oil purchase agreements with unaffiliated purchasers 

based on published price bulletins reflecting an established field posting price. As a consequence, the prices we 
receive for crude oil and our heavier liquid products move up and down in direct correlation with the oil market as it
reacts to supply and demand factors. The prices of our lighter liquid products move up and down independently of 
any relationship between the crude oil and natural gas markets. Transportation costs related to moving crude oil and 
liquids are also deducted from the price received for crude oil and liquids.

Our natural gas is sold under both long-term and short-term natural gas purchase agreements. Natural gas 

produced by us is sold at various delivery points to both unaffiliated independent marketing companies and unaffiliated
midstream companies. The prices we receive are calculated based on various pipeline indices. When there is an 
opportunity to do so, we may have our natural gas processed at San Mateo’s or third parties’ processing facilities 
to extract liquid hydrocarbons from the natural gas. We are then paid for the extracted liquids based on either a
negotiated percentage of the proceeds that are generated from the sale of the liquids or other negotiated pricing
arrangements using then-current market pricing less fixed rate processing, transportation and fractionation fees.

The prices we receive for our oil and natural gas production fluctuate widely. Factors that, directly or indirectly,

cause price fluctuations include the level of demand for oil and natural gas, the actions of the Organization of 
Petroleum Exporting Countries, Russia and certain other oil-exporting countries (“OPEC+”), weather conditions,
including hurricanes in the Gulf Coast region and severe cold weather in the Delaware Basin, oil and natural
gas storage levels, transportation and refinery capacity constraints, domestic and foreign governmental regulations,
price and availability of alternative fuels, political conditions in oil and natural gas producing regions, domestic or 
global health concerns such as COVID-19, the domestic and foreign supply of oil and natural gas, the price of foreign
imports and overall economic conditions. Decreases in these commodity prices adversely affect the carrying value
of our proved reserves and our revenues, profitability and cash flows. Short-term disruptions of our oil and natural gas
production occur from time to time due to downstream pipeline system failure, capacity issues and scheduled
maintenance, as well as maintenance and repairs involving our own well operations. These situations, if they occur,
curtail our production capabilities and ability to maintain a steady source of revenue. See “Risk Factors—Risks 
Related to our Financial Condition—Our success is dependent on the prices of oil and natural gas. Low oil and natural 
gas prices and the continued volatility in these prices may adversely affect our financial condition and our ability to
meet our capital expenditure requirements and financial obligations.”

   FORM 10-K PART I

 
 
 
 
 
30

MATADOR RESOURCES COMPANY  

The prices we receive for our oil and natural gas production often reflect a discount to the relevant benchmark
prices, such as the WTI oil price or the NYMEX Henry Hub natural gas price. The difference between the benchmark 
price and the price we receive is called a differential. Increases in the differential between the benchmark price for 
oil and natural gas and the wellhead price we receive could adversely affect our business, financial condition, results 
of operations and cash flows. See “Risk Factors—Risks Related to our Financial Condition—An increase in the
differential between the NYMEX or other benchmark prices of oil and natural gas and the wellhead price we receive 
for our production could adversely affect our business, financial condition, results of operations and cash flows.”

For the years ended December 31, 2020, 2019 and 2018, we had two, two and four significant purchasers that

accounted for approximately 65%, 67% and 60%, respectively, of our total oil, natural gas and NGL revenues. If
we lost one or more of these significant purchasers and were unable to sell our production to other purchasers on
terms we consider acceptable, it could materially and adversely affect our business, financial condition, results of
operations and cash flows. For further details regarding these purchasers, see Note 2 to the consolidated financial 
statements in this Annual Report. Such information is incorporated herein by reference.

TITLE TO PROPERTIES

We endeavor to ensure that title to our properties is in accordance with standards generally accepted in the oil

and natural gas industry. While we rely upon the judgment of oil and natural gas lease brokers and/or landmen in 
ascertaining title for certain leasehold and mineral interest acquisitions, we typically obtain detailed title opinions 
prior to drilling an oil and natural gas well. Some of our acreage is subject to agreements that require the drilling of
wells or the undertaking of other exploratory or development activities in order to retain our interests in the acreage. 
Our title to these contractual interests may be contingent upon our satisfactory fulfillment of such obligations.
Some of our properties are also subject to customary royalty interests, liens incident to financing arrangements,
operating agreements, taxes and other similar burdens that we believe will not materially interfere with the use and
operation of these properties or affect the value thereof. Generally, we intend to conduct operations, make lease
rental payments or produce oil and natural gas from wells in paying quantities, where required, prior to expiration of 
various time periods in order to avoid lease termination. See “Risk Factors—Risks Related to our Financial 
Condition—We may incur losses or costs as a result of title deficiencies in the properties in which we invest.”

We believe that we have satisfactory title to all of our material assets. Although title to these properties is subject

to customary encumbrances, such as customary interests generally retained in connection with the acquisition of 
real property, customary royalty interests and contract terms and restrictions, liens for current taxes and other
burdens, easements, restrictions and minor encumbrances customary in the oil and natural gas industry, we believe 
that none of these liens, restrictions, easements, burdens or encumbrances will materially interfere with the use 
and operation of these properties in the conduct of our business. In addition, we believe that we have obtained 
sufficient right-of-way grants and permits from public authorities and private parties for us to operate our business.
As discussed below in “—Regulation,” in January 2021, the Biden administration issued certain orders limiting 
the issuance of federal drilling permits and other necessary federal approvals. The impact of these federal actions
remains unclear, and if the restrictions do not lapse, or other limitations or prohibitions become effective, our oil
and natural gas operations on federal lands could be adversely impacted.

SEASONALITY

Generally, but not always, the demand and price levels for natural gas increase during winter and decrease 

during summer. To lessen seasonal demand fluctuations, pipelines, utilities, local distribution companies and industrial 
users utilize natural gas storage facilities and forward purchase some of their anticipated winter requirements during 
the summer. However, increased summertime demand for electricity can place increased demand on storage 
volumes. Demand for oil and heating oil is also generally higher in the winter and the summer driving season,

2020 ANNUAL REPORT

31    

although oil prices are affected more significantly by global supply and demand. Seasonal anomalies, such as
mild winters, sometimes lessen these fluctuations. Certain of our drilling, completion and other operations are also
subject to seasonal limitations where equipment may not be available during periods of peak demand or where 
weather conditions and events result in delayed operations. See “Risk Factors—Risks Related to our Operations—
Because our reserves and production are concentrated in a few core areas, problems in production and markets
relating to a particular area could have a material impact on our business.”

COMPETITION

The oil and natural gas industry is highly competitive. We compete with major and independent oil and natural 

gas companies for exploration opportunities and acreage acquisitions as well as drilling rigs and other equipment 
and labor required to drill, complete, operate and develop our properties. We also compete with public and private
midstream companies for natural gas gathering and processing opportunities, as well as produced water gathering 
and disposal and oil gathering and transportation activities in the areas in which we operate. In addition, competition
in the midstream industry is based on the geographic location of facilities, business reputation, reliability and pricing
arrangements for the services offered. San Mateo competes with other midstream companies that provide similar
services in its areas of operations, and such companies may have legacy relationships with producers in those
areas and may have a longer history of efficiency and reliability.

Many of our competitors have substantially greater financial resources, staffs, facilities and other resources. 
In addition, larger competitors may be able to absorb the burden of any changes in federal, state and local laws and 
regulations more easily than we can, which could adversely affect our competitive position. These competitors 
may be willing and able to pay more for drilling rigs, leasehold and mineral acreage, productive oil and natural gas
properties or midstream facilities and may be able to identify, evaluate, bid for and purchase a greater number 
of properties and prospects than we can. Our competitors may also be able to afford to purchase and operate their
own drilling rigs and hydraulic fracturing equipment.

Our ability to drill and explore for oil and natural gas, to acquire properties and to provide competitive midstream

services will depend upon our ability to conduct operations, to evaluate and select suitable properties and to 
consummate transactions in this highly competitive environment. In addition, many of our competitors may have 
a longer history of operations.

The oil and natural gas industry also competes with other energy-related industries in supplying the energy
and fuel requirements of industrial, commercial and individual consumers. See “Risk Factors—Risks Related to
Third Parties—Competition in the oil and natural gas industry is intense, making it more difficult for us to acquire 
properties, market oil and natural gas, provide midstream services and secure trained personnel, and our competitors
may use superior technology and data resources that we may be unable to afford.”

REGULATION

Oil and Natural Gas Regulation

Our oil and natural gas exploration, development, production, midstream and related operations are subject to 

extensive federal, state and local laws, rules and regulations. Failure to comply with these laws, rules and 
regulations can result in substantial monetary penalties or delay or suspension of operations. The regulatory burden
on the oil and natural gas industry increases our cost of doing business and affects our profitability. Because
these laws, rules and regulations are frequently amended or reinterpreted and new laws, rules and regulations are 
promulgated, we are unable to predict the future cost or impact of complying with the laws, rules and regulations
to which we are, or will become, subject. Our competitors in the oil and natural gas industry are generally subject to 
the same regulatory requirements and restrictions that affect our operations.

Texas, New Mexico, Louisiana and many other states require permits for drilling operations, drilling bonds and

reports concerning operations and impose other requirements relating to the exploration, development and
production of oil and natural gas. Many states also have laws, rules and regulations addressing conservation of oil
and natural gas and other matters, including provisions for the unitization or pooling of oil and natural gas properties,
the establishment of maximum rates of production from wells, the regulation of well spacing, the surface use 
and restoration of properties upon which wells are drilled, the prohibition, restriction or limitation of venting or flaring 
natural gas, the sourcing and disposal of water used and produced in the drilling and completion process and the
plugging and abandonment of wells. While not presently the case in the states in which we operate, some states 
restrict production to the market demand for oil and natural gas or prescribe ceiling prices for natural gas sold within
their boundaries. Additionally, some regulatory agencies have, from time to time, imposed price controls and
limitations on production by restricting the rate of flow of oil and natural gas wells below natural production capacity 
in order to conserve supplies of oil and natural gas. Moreover, each state generally imposes a production or severance 
tax with respect to the production and sale of oil, natural gas and NGLs within its jurisdiction.

Some of our oil and natural gas leases are issued by agencies of the federal government, as well as agencies 
of the states in which we operate. These leases contain various restrictions on access and development and other
requirements that may impede our ability to conduct operations on the acreage represented by these leases. In 
January 2021, the Biden administration issued: (i) an order signed by the acting Secretary of the Interior dated 
January 20, 2021 providing for a 60-day pause limiting the authority of local offices of the BLM to issue new leases 
and grant federal drilling permits and certain extensions, sundries, rights-of-way and other necessary approvals for the 
development of federal oil and natural gas leases; and (ii) an executive order signed by President Biden instructing
the Department of the Interior to pause new oil and natural gas leases on public lands pending completion of a
comprehensive review and consideration of federal oil and natural gas permitting and leasing practices (together, the
“Biden Administration Federal Lease Orders”). The impact of the federal actions remains unclear, and if the 
restrictions do not lapse, or other limitations or prohibitions become effective, our oil and natural gas operations on 
federal lands could be adversely impacted. See “Risk Factors—Risks Related to Laws and Regulations—
Approximately 28% of our leasehold and mineral acres in the Delaware Basin is located on federal lands, which are
subject to administrative permitting requirements and potential federal legislation, regulation and orders that may 
limit or restrict oil and natural gas operations on federal lands.”

Our sales of natural gas, as well as the revenues we receive from our sales, are affected by the availability, terms 

and costs of transportation. The rates, terms and conditions applicable to the interstate transportation of natural 
gas by pipelines are regulated by the Federal Energy Regulatory Commission (“FERC”) under the Natural Gas Act of
1938 (the “NGA”), as well as under Section 311 of the Natural Gas Policy Act of 1978 (the “NGPA”). Natural gas
gathering facilities are exempt from the jurisdiction of FERC under section 1(b) of the NGA, and intrastate crude oil
pipeline facilities are not subject to FERC’s jurisdiction under the Interstate Commerce Act (the “ICA”). State
regulation of natural gas gathering facilities and intrastate crude oil pipeline facilities generally includes various safety, 
environmental and, in some circumstances, nondiscriminatory take requirements or complaint-based rate regulation. 
We believe that the natural gas pipelines in our gathering systems meet the traditional tests FERC has used to 
establish a pipeline’s status as a gatherer not subject to FERC jurisdiction. In December 2018, San Mateo placed 
into service its crude oil gathering and transportation system in the Rustler Breaks asset area in Eddy County, 
New Mexico (the “Rustler Breaks Oil Pipeline System”) following an open season to gauge shipper interest in
committed crude oil interstate transportation service on the Rustler Breaks Oil Pipeline System earlier in 2018. 
The Rustler Breaks Oil Pipeline System was expanded to the Greater Stebbins Area following another open season 
in the third quarter of 2020. The Rustler Breaks Oil Pipeline System, including the expansion to the Greater Stebbins 
Area, is subject to FERC jurisdiction and includes approximately 66 miles of various diameter crude oil pipelines 
from origin points in Eddy County, New Mexico to an interconnect with Plains. We believe that the other crude oil
pipelines in our gathering systems meet the traditional tests FERC has used to establish a pipeline’s status as an 
intrastate facility not subject to FERC jurisdiction.

In 2005, Congress enacted the Energy Policy Act of 2005 (the “Energy Policy Act”). The Energy Policy Act,
among other things, amended the NGA to prohibit market manipulation in connection with the purchase or sale of
natural gas or the purchase or sale of natural gas transportation services subject to FERC jurisdiction by any entity 
and to direct FERC to facilitate transparency in the market for the sale or transportation of natural gas in interstate
commerce. The Energy Policy Act also significantly increased the penalties for violations of, among other things, the 
NGA, the NGPA or FERC rules, regulations or orders thereunder. FERC has promulgated regulations to implement
the Energy Policy Act. Should we violate the anti-market manipulation laws and related regulations, in addition to 
FERC-imposed penalties and disgorgement, we may also be subject to third-party damage claims.

Intrastate natural gas transportation is subject to regulation by state regulatory agencies (and to a limited extent 

by FERC, as noted above). The basis for intrastate regulation of natural gas transportation and the degree of 
regulatory oversight and scrutiny given to intrastate natural gas pipeline rates and services varies from state to state.
Because these regulations will apply to all intrastate natural gas shippers within the same state on a comparable
basis, we believe that regulation in any states in which we operate will not affect our operations in any way that is
materially different from our competitors that are similarly situated.

As mentioned above, in December 2018, San Mateo placed into service the Rustler Breaks Oil Pipeline System. 

The Rustler Breaks Oil Pipeline System is subject to regulation by FERC under the ICA and the Energy Policy Act 
of 1992 (the “EP Act”). The ICA and its implementing regulations give FERC authority to regulate the rates charged 
for service on interstate common carrier pipelines and generally require the rates and practices of interstate crude
oil pipelines to be just, reasonable, not unduly discriminatory and not unduly preferential. The ICA also requires
tariffs that set forth the rates an interstate crude oil pipeline company charges for providing transportation services
on its FERC-jurisdictional pipelines, as well as the rules and regulations governing these services, to be maintained on
file with FERC and posted publicly. The EP Act and its implementing regulations also generally allow interstate
crude oil pipelines to annually index their rates up to a prescribed ceiling level and require that such pipelines index 
their rates down to the prescribed ceiling level if the index is negative.

The price we receive from the sale of oil and NGLs will be affected by the availability, terms and cost of

transportation of such products to market. As noted above, under rules adopted by FERC, interstate oil pipelines can 
change rates based on an inflation index, though other rate mechanisms may be used in specific circumstances. 
Intrastate oil pipeline transportation rates are subject to regulations promulgated by state regulatory commissions, 
which vary from state to state. We are not able to predict with certainty the effects, if any, of these regulations on
our operations.

In 2007, the Energy Independence & Security Act of 2007 (the “EISA”) went into effect. The EISA, among other 

things, prohibits market manipulation by any person in connection with the purchase or sale of crude oil, gasoline 
or petroleum distillates at wholesale in contravention of such rules and regulations that the Federal Trade Commission 
may prescribe, directs the Federal Trade Commission to enforce the regulations and establishes penalties for 
violations thereunder.

The Pipeline and Hazardous Materials Safety Administration (“PHMSA”) imposes pipeline safety requirements 
on regulated pipelines and gathering lines pursuant to its authority under the Natural Gas Pipeline Safety Act and the
Hazardous Liquid Pipeline Safety Act, each as amended. The Rustler Breaks Oil Pipeline System is subject to
PHMSA oversight. The Department of Transportation, through PHMSA, has established rules regarding integrity
management programs for interstate oil pipelines, including the Rustler Breaks Oil Pipeline System. In recent years, 
pursuant to these laws and the Pipeline Safety, Regulatory Certainty, and Job Creation Act of 2011, PHMSA has 
expanded its regulation of gathering lines, subjecting previously unregulated pipelines to requirements regarding
damage prevention, corrosion control, public education programs, maximum allowable operating pressure limits 
and other requirements. Certain of our natural gas gathering lines are federally “regulated gathering lines” subject to

   FORM 10-K PART I

 
 
34

MATADOR RESOURCES COMPANY  

PHMSA requirements. On April 8, 2016, PHMSA published a notice of proposed rulemaking that would amend
existing integrity management requirements, expand assessment and repair requirements in areas with medium
population densities and extend regulatory requirements to onshore natural gas gathering lines that are currently 
exempt. On January 13, 2017, PHMSA issued, but did not publish, a similar proposed rule for hazardous liquids (i.e.,
oil) pipelines and gathering lines. It is unclear when or if this rule will go into effect as, on January 20, 2017, the 
Trump administration requested that all regulations that had been sent to the Office of the Federal Register, but not
yet published, be immediately withdrawn for further review. In addition, states have adopted regulations, similar to
existing PHMSA regulations, for intrastate gathering and transmission lines. See “Risk Factors—Risks Related
to Laws and Regulations—We may incur significant costs and liabilities resulting from compliance with pipeline
safety regulations.”

Additional expansion of pipeline safety requirements or our operations could subject us to more stringent or costly

safety standards, which could result in increased operating costs or operational delays.

U.S. Federal and State Taxation

The federal, state and local governments in the areas in which we operate impose taxes on the oil and natural

gas products we sell and, for many of our wells, sales and use taxes on significant portions of our drilling and 
operating costs. Many states have raised state taxes on energy sources or state taxes associated with the extraction 
of hydrocarbons, and additional increases may occur. In 2019, a bill was introduced in the New Mexico Senate to 
add a surtax on natural gas processors that would have started at $0.60 per MMBtu in 2020 and escalated to $3.00
per MMBtu by 2024. Although the bill did not pass, any such surtax would adversely affect the ability of San Mateo 
and other natural gas processors to operate in New Mexico and would adversely affect the prices we receive for our 
natural gas processed in New Mexico. In addition, from time to time there has been a significant amount of
discussion by legislators and presidential administrations concerning a variety of energy tax proposals, including
proposals that would eliminate allowing small U.S. oil and natural gas companies to deduct intangible drilling costs 
as incurred and percentage depletion. Changes to tax laws could adversely affect our business and our financial
results. See “Risk Factors—Risks Related to Laws and Regulations—We are subject to federal, state and local 
taxes and may become subject to new taxes or have eliminated or reduced certain federal income tax deductions 
currently available with respect to oil and natural gas exploration and production activities as a result of future 
legislation, which could adversely affect our business, financial condition, results of operations and cash flows”
and “Risk Factors—Risks Related to Laws and Regulations—The Tax Cuts and Jobs Act may impact our ability 
to fully utilize our interest expense deductions and net operating loss carryovers to fully offset our taxable income
in future periods.”

Hydraulic Fracturing Policies and Procedures

We use hydraulic fracturing as a means to maximize the recovery of oil and natural gas in almost every well that 
we drill and complete. Our engineers responsible for these operations attend specialized hydraulic fracturing training
programs taught by industry professionals. Although average drilling and completion costs for each area will vary, 
as will the cost of each well within a given area, on average approximately one-half to two-thirds of the total well
costs for our horizontal wells are attributable to overall completion activities, which are primarily focused on hydraulic
fracture treatment operations. These costs are treated in the same way as all other costs of drilling and completion of
our wells and are included in and funded through our normal capital expenditure budget. A change to any federal 
and state laws and regulations governing hydraulic fracturing could impact these costs and adversely affect 
our business and financial results. See “Risk Factors—Risks Related to Laws and Regulations—Federal and state 
legislation and regulatory initiatives relating to hydraulic fracturing could result in increased costs and additional 
operating restrictions or delays.”

The protection of groundwater quality is important to us. We believe that we follow all state and federal 

regulations and apply industry standard practices for groundwater protection in our operations. These measures are 
subject to close supervision by state and federal regulators (including the BLM, with respect to federal acreage).

Although rare, if the cement and steel casing used in well construction requires remediation, we deal with 
these problems by evaluating the issue and running diagnostic tools, including cement bond logs and temperature
logs, and conducting pressure testing, followed by pumping remedial cement jobs and taking other appropriate 
remedial measures.

The vast majority of our hydraulic fracturing treatments are made up of water and sand or other kinds of 
man-made proppants. We use major hydraulic fracturing service companies that track and report chemical additives 
that are used in fracturing operations as required by the appropriate governmental agencies. These service
companies fracture stimulate thousands of wells each year for the industry and invest millions of dollars to protect
the environment through rigorous safety procedures and also work to develop more environmentally friendly 
fracturing fluids. We follow safety procedures and monitor all aspects of our fracturing operations in an attempt
to ensure environmental protection. We do not pump any diesel in the fluid systems of any of our fracture
stimulation procedures.

While current fracture stimulation procedures utilize a significant amount of water, we typically recover less than 

10% of this fracture stimulation water before produced water becomes a significant portion of the fluids produced. 
All produced water, including fracture stimulation water, is either recycled or disposed of in permitted and regulated 
disposal facilities in a way that is designed to avoid any impact to surface waters. Since mid-2015, we have been 
recycling a portion of our produced water in certain of our Delaware Basin asset areas. Recycling produced water
mitigates the need for produced water disposal and also provides cost savings to us.

Environmental, Health and Safety Regulation

The exploration, development, production, gathering and processing of oil and natural gas, including the operation

of produced water injection and disposal wells, are subject to various federal, state and local environmental laws 
and regulations. These laws and regulations can increase the costs of planning, designing, drilling, completing and 
operating oil and natural gas wells, midstream facilities and produced water injection and disposal wells. Our
activities are subject to a variety of environmental laws and regulations, including but not limited to: the Oil Pollution 
Act of 1990 (the “OPA 90”), the Clean Water Act (the “CWA”), the Comprehensive Environmental Response, 
Compensation and Liability Act (“CERCLA”), the Resource Conservation and Recovery Act (“RCRA”), the Clean Air
Act (the “CAA”), the Safe Drinking Water Act (the “SDWA”) and the Occupational Safety and Health Act (“OSHA”),
as well as comparable state statutes and regulations. We are also subject to regulations governing the handling,
transportation, storage and disposal of wastes generated by our activities and naturally occurring radioactive
materials (“NORM”) that may result from our oil and natural gas operations. Administrative, civil and criminal fines
and penalties may be imposed for noncompliance with these environmental laws and regulations, and violations 
and liability with respect to these laws and regulations could also result in remedial clean-ups, natural resource 
damages, permit modifications or revocations, operational interruptions or shutdowns and other liabilities. Additionally, 
these laws and regulations require the acquisition of permits or other governmental authorizations before
undertaking some activities, may require notice to stakeholders of proposed and ongoing operations, limit or prohibit
other activities because of protected wetlands, areas or species and require investigation and cleanup of pollution.
These laws, rules and regulations may also restrict the production rate of oil and natural gas below the rate that
would otherwise be possible. We expect to remain in compliance in all material respects with currently applicable 
environmental laws and regulations and do not expect that these laws and regulations will have a material adverse
impact on us.

The OPA 90 and its regulations impose requirements on “responsible parties” related to the prevention of 
crude oil spills and liability for damages resulting from oil spills into or upon navigable waters, adjoining shorelines or
in the exclusive economic zone of the United States. A “responsible party” under the OPA 90 may include the 
owner or operator of an onshore facility. The OPA 90 subjects responsible parties to strict, joint and several financial
liability for removal and remediation costs and other damages, including natural resource damages, caused by an
oil spill that is covered by the statute. Failure to comply with the OPA 90 may subject a responsible party to civil or
criminal enforcement action.

The CWA and comparable state laws impose restrictions and strict controls regarding the discharge of produced
waters, fill materials and other materials into navigable waters. These controls have become more stringent over the
years, and it is possible that additional restrictions will be imposed in the future. Permits are required to discharge
pollutants into certain state and federal waters and to conduct construction activities in those waters and wetlands.
The CWA and comparable state statutes provide for civil, criminal and administrative penalties for any unauthorized 
discharges of oil and other pollutants and impose liability for the costs of removal or remediation of contamination 
resulting from such discharges. In September 2015, a rule issued by the Environmental Protection Agency (the
“EPA”) and U.S. Army Corps of Engineers (the “Corps”) to revise the definition of “waters of the United States”
(“WOTUS”) for all CWA programs, thereby defining the scope of the EPA’s and the Corps’ jurisdiction, became 
effective. The EPA rescinded this rule in 2019, however, and promulgated the Navigable Waters Protection Rule
(the “NWPR”) in 2020. The NWPR defined what waters qualify as navigable waters of the United States and are
under CWA jurisdiction. This new rule has generally been viewed as narrowing the scope of WOTUS as compared 
to the 2015 rule, but there is currently litigation in multiple federal district courts challenging the rescission of the 
2015 rule and the promulgation of the NWPR.

Separately, in April 2020, a Montana federal judge vacated the Corps’ Nationwide Permit (“NWP”) 12 and enjoined
the Corps from authorizing any dredge or fill activities under NWP 12 until the agency completed formal consultation 
with the U.S. Fish and Wildlife Service (the “USFWS”) under the Endangered Species Act (the “ESA”) regarding
NWP 12 generally. The court later revised its order to vacate NWP 12 only as it relates to the construction of new
oil and natural gas pipelines, and that order is currently on appeal in the Ninth Circuit Court of Appeals. However,
the Montana district court’s decision spawned other NWP 12-based challenges and may indicate that the rest of the
NWPs, some of which are relied upon for oil and natural gas projects, are vulnerable to similar challenge. The
Corps has proposed a new set of NWPs, which would replace the NWPs for dredge or fill discharges into WOTUS 
that the Corps last issued and made available in 2017, but has so far elected not to consult with the USFWS. If 
this status quo does not change, when the Corp re-issues the NWPs, the NWPs could be subject to the same 
legal challenges unless and until the ongoing litigation resolves the questions surrounding the need for a formal 
ESA consultation.

CERCLA, also known as the “Superfund” law, imposes liability, without regard to fault or the legality of the 

original conduct, on various classes of persons that are considered to have contributed to the release of a 
“hazardous substance” into the environment. These persons include the owner or operator of the site where the
release occurred and companies that disposed of, or arranged for the disposal of, the hazardous substances
found at the site. Persons who are responsible for releases of hazardous substances under CERCLA may be subject
to joint and several liability for the costs of cleaning up the hazardous substances and for damages to natural
resources. In addition, it is not uncommon for neighboring landowners and other third parties to file claims for 
personal injury and property damage allegedly caused by hazardous substances released into the environment. 
Although CERCLA generally exempts petroleum from the definition of hazardous substances, our operations
may, and in all likelihood will, involve the use or handling of materials that are classified as hazardous substances
under CERCLA. Each state also has environmental cleanup laws analogous to CERCLA.

RCRA and comparable state and local statutes govern the management, including treatment, storage and 
disposal, of both hazardous and nonhazardous solid wastes. We generate hazardous and nonhazardous solid
waste in connection with our routine operations. RCRA includes a statutory exemption that allows many wastes 
associated with crude oil and natural gas exploration and production to be classified as nonhazardous waste. 
A similar exemption is contained in many of the state counterparts to RCRA. Not all of the wastes we generate fall 
within these exemptions. At various times in the past, proposals have been made to amend RCRA to eliminate
the exemption applicable to crude oil and natural gas exploration and production wastes. Repeal or modifications
of this exemption by administrative, legislative or judicial process, or through changes in applicable state statutes, 
would increase the volume of hazardous waste we are required to manage and dispose of and would cause us, as 
well as our competitors, to incur increased operating expenses. Hazardous wastes are subject to more stringent 
and costly disposal requirements than nonhazardous wastes.

The CAA, as amended, restricts the emission of air pollutants from many sources, including oil and natural gas 

production. In addition, certain states have comparable legislation, which may be more restrictive than the CAA. 
These laws and any implementing regulations impose stringent air permit requirements and require us to obtain
pre-approval for the construction or modification of certain projects or facilities expected to produce air emissions,
or to use specific equipment or technologies to control emissions. Federal and state regulatory agencies can impose 
administrative, civil and criminal penalties for non-compliance with air permits or other requirements of the CAA 
and associated state laws and regulations. See “Risk Factors—Risks Related to Laws and Regulations—New
regulations on all emissions from our operations could cause us to incur significant costs.” Internationally, in 2015,
the United States participated in the United Nations Conference on Climate Change, which led to the creation of 
the Paris Agreement. The Paris Agreement, which was signed by the United States in April 2016, requires countries 
to review and “represent a progression” in their intended nationally determined contributions, which set 
greenhouse gas emission reduction goals, every five years beginning in 2020. While the United States exited the 
Paris Agreement in November 2020, effective February 19, 2021, President Biden caused the United States 
to rejoin the Paris Agreement. In January 2019, New Mexico’s governor signed an executive order declaring that 
New Mexico would support the goals of the Paris Agreement by joining the U.S. Climate Alliance, a bipartisan 
coalition of governors committed to reducing greenhouse gas emissions consistent with the goals of the Paris 
Agreement. The stated objective of the executive order is to achieve a statewide reduction in greenhouse gas 
emissions of at least 45% by 2030 as compared to 2005 levels. The executive order also requires New Mexico 
regulatory agencies to create an “enforceable regulatory framework” to ensure methane emission reductions.
Following that executive order, the New Mexico Oil Conservation Division (the “NMOCD”), New Mexico
Environment Department (the “NMED”) and New Mexico legislature have proposed various rules, regulations and 
bills regarding the reduction of natural gas waste and the control of emissions that would, among other items, 
require upstream and midstream operators to reduce natural gas waste by a fixed amount each year and achieve a
98% natural gas capture rate by the end of 2026.

Changes in environmental laws and regulations occur frequently, and any changes that result in more stringent 

and costly waste handling, storage, transport, disposal, cleanup or operating requirements could materially
adversely affect our operations and financial condition, as well as those of the oil and natural gas industry in general.
For instance, recent scientific studies have suggested that emissions of certain gases, commonly referred to as 
“greenhouse gases,” and including carbon dioxide and methane, may be contributing to the warming of the Earth’s
atmosphere. Based on these findings, the EPA has begun adopting and implementing a comprehensive suite 
of regulations to restrict emissions of greenhouse gases under existing provisions of the CAA. Legislative and 
regulatory initiatives related to climate change and greenhouse gas emissions could, and in all likelihood would, 
require us to incur increased operating costs adversely affecting our profits and could adversely affect demand for
the oil and natural gas we produce, depressing the prices we receive for oil and natural gas. See “Risk Factors—
Risks Related to Laws and Regulations—Legislation or regulations restricting emissions of greenhouse gases could
result in increased operating costs and reduced demand for the oil, natural gas and NGLs we produce, while the

physical effects of climate change could disrupt our production and cause us to incur significant costs in preparing 
for or responding to those effects” and “Risk Factors—Risks Related to Laws and Regulations—New regulations 
on all emissions from our operations could cause us to incur significant costs.”

We own and operate underground injection wells throughout our areas of operation. Underground injection is 
the subsurface placement of fluid through a well, such as the reinjection of brine produced and separated from oil
and natural gas production. Underground injection allows us to safely and economically dispose of produced
water. The SDWA establishes a regulatory framework for underground injection, the primary objective of which is to 
ensure the mechanical integrity of the injection apparatus and to prevent migration of fluids from the injection zone
into underground sources of drinking water. In addition, the Railroad Commission of Texas (the “RRC”) and the
NMOCD require injected fluids to be confined to a permitted injection interval to aid in the protection of potentially 
productive intervals. The disposal of hazardous waste by underground injection is subject to stricter requirements
than the disposal of produced water. Failure to obtain, or abide by the requirements for the issuance of, necessary
permits could subject us to civil and/or criminal enforcement actions and penalties. In addition, in some instances, 
the operation of underground injection wells has been alleged to cause earthquakes (induced seismicity) as a result
of flawed well design or operation. This has resulted in stricter regulatory requirements in some jurisdictions
relating to the location and operation of underground injection wells. In addition, a number of lawsuits have been 
filed in some states alleging that fluid injection or oil and natural gas extraction have caused damage to neighboring
properties or otherwise violated state and federal rules regulating waste disposal. In response to these concerns, 
regulators in some states are seeking to impose additional requirements, including requirements regarding the 
permitting of salt water disposal wells or otherwise, to assess the relationship between seismicity and the use of
such wells. For example, in October 2014, the RRC adopted disposal well rule amendments designed, among
other things, to require applicants for new disposal wells that will receive non-hazardous produced water or other oil 
and natural gas waste to conduct seismic activity searches utilizing the U.S. Geological Survey. The searches are 
intended to determine the potential for earthquakes within a circular area of 100 square miles around a proposed new 
disposal well. If the permittee or an applicant for a disposal well permit fails to demonstrate that the produced
water or other fluids are confined to the disposal zone, or if scientific data indicates such a disposal well is likely to 
be, or determined to be, contributing to seismic activity, then the RRC may deny, modify, suspend or terminate 
the permit application or existing operating permit for that disposal well. The RRC has used this authority to deny 
permits for waste disposal wells. The potential adoption of federal, state and local legislation and regulations 
intended to address induced seismicity in the areas in which we operate could restrict our drilling and production
activities, as well as our ability to dispose of produced water gathered from such activities, which could result in 
increased costs and additional operating restrictions or delays.

Our activities involve the use of hydraulic fracturing. For more information on our hydraulic fracturing operations, 

see “—Hydraulic Fracturing Policies and Procedures.” Hydraulic fracturing is generally exempted from federal 
regulation as underground injection (unless diesel is a component of the fracturing fluid) under the SDWA. The
process of hydraulic fracturing is typically regulated by state oil and natural gas commissions. Various policy makers,
regulatory agencies and political candidates at the federal, state and local levels have proposed restrictions on
hydraulic fracturing, including its outright prohibition. In January 2021, the Biden administration issued the Biden
Administration Federal Lease Orders. The impact of these federal actions remains unclear, and if the restrictions do 
not lapse, or other limitations or prohibitions become effective, they could have an adverse impact on our business, 
financial condition, results of operations and cash flows. Restrictions on hydraulic fracturing could also reduce the 
amount of oil and natural gas that we are ultimately able to produce. Some states and localities have placed 
additional regulatory burdens upon hydraulic fracturing activities and, in some areas, severely restricted or prohibited 
those activities. In recent years, various bills have been introduced in the New Mexico legislature to place a
moratorium on, ban or otherwise restrict hydraulic fracturing, including prohibiting the injection of fresh water in
such operations. In addition, separate and apart from the referenced potential connection between injection wells
and seismicity, concerns have been raised that hydraulic fracturing activities may be correlated to induced seismicity.

The scientific community and regulatory agencies at all levels are studying the possible linkage between oil and
natural gas activity and induced seismicity, and some state regulatory agencies have modified their regulations or 
guidance to mitigate potential causes of induced seismicity. If the exemption for hydraulic fracturing is removed
from the SDWA, or if other legislation is enacted at the federal, state or local level imposing any restrictions on the
use of hydraulic fracturing, this could have a significant impact on our financial condition, results of operations and
cash flows. Additional burdens upon hydraulic fracturing, such as reporting or permitting requirements, would result
in additional expense and delay in our operations. See “Risk Factors—Risks Related to Laws and Regulations—
Federal and state legislation and regulatory initiatives relating to hydraulic fracturing could result in increased costs
and additional operating restrictions or delays” and “Risk Factors—Risks Related to Laws and Regulations—
Approximately 28% of our leasehold and mineral acres in the Delaware Basin is located on federal lands, which are 
subject to administrative permitting requirements and potential federal legislation, regulation and orders that may 
limit or restrict oil and natural gas operations on federal lands.”

Oil and natural gas exploration and production operations and other activities have been conducted on some 

of our properties by previous owners and operators. Materials from these operations remain on some of the
properties, and, in some instances, require remediation. In addition, we occasionally must agree to indemnify sellers
of producing properties against some of the liability for environmental claims associated with the properties we
purchase. While we do not believe that costs we incur for compliance with environmental regulations and remediating
previously or currently owned or operated properties will be material, we cannot provide any assurances that
these costs will not result in material expenditures that adversely affect our profitability.

Additionally, in the course of our routine oil and natural gas operations, surface spills and leaks, including casing

leaks, of oil, produced water or other materials may occur, and we may incur costs for waste handling and
environmental compliance. It is also possible that our oil and natural gas operations may require us to manage NORM.
NORM is present in varying concentrations in sub-surface formations, including hydrocarbon reservoirs, and may
become concentrated in scale, film and sludge in equipment that comes in contact with crude oil and natural gas 
production and processing streams. Some states, including Texas, New Mexico and Louisiana, have enacted
regulations governing the handling, treatment, storage and disposal of NORM. Moreover, we will be able to control 
directly the operations of only those wells we operate. Despite our lack of control over wells owned partly by
us but operated by others, the failure of the operator to comply with the applicable environmental regulations may,
in certain circumstances, be attributable to us.

We are subject to the requirements of OSHA and comparable state statutes. The OSHA Hazard Communication 

Standard, the “community right-to-know” regulations under Title III of the federal Superfund Amendments and
Reauthorization Act and similar state statutes require us to organize information about hazardous materials used, 
released or produced in our operations. Certain of this information must be provided to employees, state and
local governmental authorities and local citizens. We are also subject to the requirements and reporting set forth in 
OSHA workplace standards.

The ESA was established to protect endangered and threatened species. Pursuant to the ESA, if a species is 

listed as threatened or endangered, restrictions may be imposed on activities adversely affecting that species’ 
habitat. Similar protections are offered to migratory birds under the Migratory Bird Treaty Act and to bald and golden 
eagles under the Bald and Golden Eagle Protection Act. The USFWS must also designate the species’ critical
habitat and suitable habitat as part of the effort to ensure survival of the species. A critical habitat or suitable habitat
designation could result in material restrictions on land use and may materially impact oil and natural gas 
development. Our oil and natural gas operations in certain of our operating areas could also be adversely affected
by seasonal or permanent restrictions on drilling activity designed to protect certain wildlife in the Delaware Basin 
and other areas in which we operate. See “Risk Factors—Risks Related to Laws and Regulations—We are subject
to government regulation and liability, including complex environmental laws, which could require significant 
expenditures.” Our ability to maximize production from our leases may be adversely impacted by these restrictions.

As of December 31, 2020, approximately 28% of our Delaware Basin acreage position, including all of the

BLM Acquisition, consists of federal leasehold administered by the BLM. Permitting for oil and natural gas activities
on federal lands can take significantly longer than the permitting process for oil and natural gas activities not located 
on federal lands. Delays in obtaining necessary permits can disrupt our operations and have an adverse effect on 
our business. These BLM leases contain relatively standardized terms and require compliance with detailed 
regulations and orders, which are subject to change. These operations are also subject to BLM rules regarding
engineering and construction specifications for production facilities, safety procedures, the valuation of production, 
the payment of royalties, the removal of facilities, the posting of bonds, hydraulic fracturing, the control of air 
emissions and other areas of environmental protection. These rules could result in increased compliance costs for 
our operations, which in turn could have an adverse effect on our business and results of operations. Under
certain circumstances, the BLM may require our operations on federal leases to be suspended or terminated. In
January 2021, the Biden administration issued the Biden Administration Federal Lease Orders. The impact of these 
federal actions remains unclear, and if the restrictions do not lapse, or other limitations or prohibitions become 
effective, our oil and natural gas operations on federal lands could be adversely impacted.

Oil and natural gas exploration and production activities on federal lands are also subject to the National 
Environmental Policy Act (“NEPA”). NEPA requires federal agencies, including the Department of Interior, to 
evaluate major agency actions having the potential to significantly impact the environment. In the course of 
such evaluations, an agency will prepare an environmental assessment that assesses impacts that are “reasonably 
foreseeable” and have a “reasonably close causal relationship” to the agency action under review and, if 
necessary, will prepare a more detailed environmental impact statement that may be made available for public 
review and comment. This process, including any additional requirements or procedures that may be included 
in the process, has the potential to delay or even halt development of future oil and natural gas projects with 
NEPA applicability.

We have not in the past been, and do not anticipate in the near future to be, required to expend amounts that
are material in relation to our total capital expenditures as a result of environmental laws and regulations, but since
these laws and regulations are periodically amended, we are unable to predict the ultimate cost of compliance.
We have no assurance that more stringent laws and regulations protecting the environment will not be adopted or
that we will not otherwise incur material expenses in connection with environmental laws and regulations in the
future. See “Risk Factors—Risks Related to Laws and Regulations—We are subject to government regulation and 
liability, including complex environmental laws, which could require significant expenditures.”

The clear trend in environmental regulation is to place more restrictions and limitations on activities that may

affect the environment. Any changes in environmental laws and regulations or re-interpretation of enforcement 
policies that result in more stringent and costly permitting, emissions control, waste handling, storage, transport, 
disposal or remediation requirements could have a material adverse effect on our operations and financial condition. 
We may be unable to pass on such increased compliance costs to our customers. Moreover, accidental releases 
or spills may occur in the course of our operations, and we have no assurance that we will not incur significant costs 
and liabilities as a result of such releases or spills, including any third-party claims for damage to property, natural 
resources or persons.

We maintain insurance against some, but not all, potential risks and losses associated with our industry and 
operations. We generally do not carry business interruption insurance. For some risks, we may not obtain insurance 
if we believe the cost of available insurance is excessive relative to the risks presented. In addition, pollution and
environmental risks generally are not fully insurable. If a significant accident or other event occurs and is not fully 
covered by insurance, it could materially adversely affect our financial condition, results of operations and cash flows. 
See “Risk Factors—Risks Related to our Operations—Insurance against all operational risks is not available to us.”

OFFICE LOCATION

Our corporate headquarters are located at One Lincoln Centre, 5400 LBJ Freeway, Suite 1500, Dallas, Texas 75240.

HUMAN CAPITAL

At December 31, 2020, we had 288 full-time employees. We believe that our relationships with our employees 

are satisfactory. No employee is covered by a collective bargaining agreement. From time to time, we use the
services of independent consultants and contractors to perform various professional services, including in the areas 
of geology and geophysics, land, production and midstream operations, construction, design, well site surveillance 
and supervision, permitting and environmental assessment, legal and income tax preparation and accounting 
services. Independent contractors, at our request, drill all of our wells and usually perform field and on-site 
production operation services for us, including midstream services, facilities construction, pumping, maintenance,
dispatching, inspection and testing. If significant opportunities for company growth arise and require additional 
management and professional expertise, we will seek to employ qualified individuals to fill positions where that 
expertise is necessary to develop those opportunities.

Employee Recruiting, Retention and Professional Development

We promote inclusion throughout our organization. We respect cultural diversity and do not tolerate harassment 

or discrimination of any kind, including, but not limited to, discrimination based on race, color, ethnicity, religion, 
gender, sexual orientation, gender identity, age, national origin, disability and veteran or marital status.

Our employees are our most important asset. We have invested the time, attention and resources necessary to 
recruit, retain and develop an extraordinary team. We offer a comprehensive compensation package with base pay,
discretionary bonus and equity incentive opportunities, paid time off, 401(k) matching contributions and an
affordable and comprehensive health insurance program, among other benefits. We also provide employees the 
opportunity to have significant responsibility and daily interaction with our executive management and team leaders.

We encourage continuing education and study, requiring every employee to complete at least 40 hours of 
professional training annually. In 2020, for example, our employees completed approximately 15,000 hours of 
continuing education and study. We also have a formal leadership program that fosters the development and growth 
of many of our staff with regular meetings and opportunities to enhance their leadership skills.

Proactive Safety Culture

We are proud to have a company culture that emphasizes safety throughout our operations. Between 2017 and

2020, we estimate our employees have worked approximately 2.1 million combined hours without experiencing a 
single lost time accident. We attribute much of that to the efforts of our Health, Safety and Environmental (“HSE”) 
group, which is devoted to proactively minimizing safety risks and addressing any potential areas of concern.

We emphasize the importance of recruiting and maintaining a quality HSE group, and we believe it is important 

that our HSE group has actual hands-on experience in the field to understand the challenges and issues that can 
arise. Our HSE group’s experience allows us to understand the technical issues faced by our field employees and
contractors, as well as maintain an open dialogue with community leaders in the areas we operate about potential
safety issues and mitigation efforts.

ITEM 1A. RISK FACTORS.

SUMMARY OF RISK FACTORS

The following is a summary of some of the risks and uncertainties that could materially adversely affect our 
business, financial condition and results of operations. You should read this summary together with the more detailed 
risk factors contained below.

Risks Related to our Financial Condition

• Our success is dependent on the prices of oil and natural gas, the volatility of which may adversely affect

our financial condition.

• We face numerous risks related to the COVID-19 global pandemic, including its impact on global oil demand.

• Our business requires substantial capital expenditures that may exceed our cash flows from operations and

potential borrowings.

• Our oil and natural gas reserves are estimated and may not reflect the actual volumes we will recover, and 

we may be required to write down the carrying value of our proved properties under accounting rules.

• Unless we replace our oil and natural gas reserves, our reserves and production will decline, which would

adversely affect our business, financial condition, results of operations and cash flows.

• Hedging transactions, or the lack thereof, may limit our potential gains and could result in financial losses.

• An increase in the differential between the NYMEX or other benchmark prices of oil and natural gas and the

wellhead price we receive for our production could adversely affect our financial condition.

• A component of our growth may come through acquisitions, which we may be unable to complete or

which may require us to incur certain liabilities, risks or title deficiencies.

• Our ability to complete dispositions of assets may be subject to factors beyond our control, and in certain

cases we may be required to retain liabilities for certain matters.

2020 ANNUAL REPORT

43    

Risks Related to our Liquidity

• We may not be able to generate sufficient cash to fund our capital expenditures, service all of our 

indebtedness and pay dividends to our shareholders, and we may incur additional indebtedness, which
could reduce our financial flexibility.

• The borrowing base under our Credit Agreement is subject to periodic redetermination, and we are 

subject to interest rate risk under our Credit Agreement and San Mateo’s revolving credit facility (the
“San Mateo Credit Facility”).

• The terms of the agreements governing our indebtedness impose significant operating and financial 

restrictions.

• Our credit rating may be downgraded, which could reduce our financial flexibility and increase interest expense.

• The payment of dividends will be at the discretion of our Board of Directors and subject to numerous 

factors, and we do not presently intend to repurchase any shares of our common stock.

Risks Related to our Operations

• Drilling for and producing oil and natural gas are highly speculative and involve a high degree of operational, 

geological and financial risk, and insurance against all such risks is not available to us.

• Because our reserves and production are concentrated in a few core areas, problems in production and

markets relating to a particular area could have a material impact on our business.

• There is no guarantee that we will be successful in optimizing our spacing, drilling and completions

techniques in order to maximize our rate of return, and multi-well pad drilling may result in volatility in our
operating results.

• Certain of our properties are in areas that may have been partially depleted or drained by offset wells, and

certain of our wells may be adversely affected by actions of other operators.

• The unavailability or high cost of equipment and services, supplies and personnel could adversely affect our
ability to establish and execute exploration and development plans within budget and on a timely basis.

• We may be unable to acquire adequate supplies of water for our drilling and hydraulic fracturing operations or 
unable to dispose of the water we use at a reasonable cost and pursuant to applicable environmental rules.

• Regulatory changes could prevent our ability to continue to pool wells in the manner we have been.

• Midstream projects are subject to risks of construction delays and cost over-runs.

• Our identified drilling locations are scheduled over several years, making them susceptible to uncertainties

and lease expirations that could materially alter our plans.

MATADOR RESOURCES COMPANY 

Risks Related to Third Parties

• We depend upon several significant purchasers for the sale of most of our production, and financial

difficulties encountered by such purchasers, other operators or third parties could decrease our cash flows
from operations.

• The marketability of our production is dependent upon gathering, processing and transportation facilities.

• We conduct a portion of our operations through joint ventures, including San Mateo, which subjects us to

certain risks.

• Because of the natural decline in production in the regions of San Mateo’s midstream operations, San Mateo’s

long-term success depends on its ability to obtain new sources of products.

• We have entered into certain long-term contracts that require us to pay fees to our service providers based 

on minimum volumes regardless of actual volume throughput.

• Competition in our industry is intense, making it more difficult for us to acquire properties, market production, 
provide midstream services and secure trained personnel, and our competitors may use superior technology
and data resources.

• We have limited control over activities on properties we do not operate.

Risks Related to Laws and Regulations

• As of December 31, 2020, approximately 28% of our leasehold and mineral acres in the Delaware Basin is

located on federal lands, which are subject to various requirements and regulations.

• We are subject to government regulation, including environmental laws, which could require significant

expenditures.

• We are subject to tax laws, and changes thereto could eliminate or reduced certain federal income tax 

deductions or net operating loss carryforwards currently available.

• Legislative and regulatory initiatives relating to hydraulic fracturing, induced seismicity, emissions and

climate change could result in increased costs, operating restrictions or delays.

• We may incur significant costs and liabilities resulting from compliance with pipeline safety regulations,

and the rates of our regulated assets are subject to oversight by regulators, which could adversely affect
our revenues.

• Derivatives legislation adopted by Congress could limit our ability to hedge commodity price risks.

Risks Relating to Our Common Stock

• The price of our common stock is volatile and may fluctuate substantially in the future.

• Conservation measures and a negative shift in market perception towards the oil and natural gas industry

could adversely affect our stock price.

• Our directors and executive officers own a significant percentage of our equity, which could give them
influence in transactions and other matters, and their interests could differ from other shareholders.

• Our Board can authorize the issuance of preferred stock, which could diminish the rights of holders of

our common stock and make a change of control of the Company more difficult even if it might benefit our
shareholders.

General Risk Factors

• We may have difficulty managing growth in our business.

• Our success depends on our ability to retain our key personnel.

•

If we fail to maintain effective internal control over financial reporting, our ability to accurately report our
financial results could be adversely affected.

• A cyber incident could occur and result in information theft, data corruption, operational disruption or 

financial loss.

• Our governing documents and Texas law may have anti-takeover effects that could prevent a change in control.

• We operate in a litigious environment and may be involved in legal proceedings that could have an 

adverse effect on our results of operations and financial condition.

RISKS RELATED TO OUR FINANCIAL CONDITION

Our success is dependent on the prices of oil and natural gas. Low oil and natural gas prices and the 
continued volatility in these prices may adversely affect our financial condition and our ability to meet our 
capital expenditure requirements and financial obligations.

The prices we receive for the oil and natural gas we produce heavily influence our revenue, profitability, cash
flow available for capital expenditures, the repayment of debt and the payment of cash dividends, if any, access 
to capital, borrowing capacity under our Credit Agreement and future rate of growth. Oil and natural gas are
commodities and, therefore, their prices are subject to wide fluctuations in response to relatively minor changes 
in supply and demand. Historically, the markets for oil and natural gas have been volatile and will likely continue to
be volatile in the future. For the year ended December 31, 2020, oil prices averaged $39.34 per Bbl, ranging from 
a high of $63.27 per Bbl in early January to a low of ($37.63) per Bbl in mid-April, based upon the WTI oil futures
contract price for the earliest delivery date. For the year ended December 31, 2020, natural gas prices averaged 
$2.13 per MMBtu, as compared to $2.53 per MMbtu for the year ended December 31, 2019, based upon the
NYMEX Henry Hub natural gas futures contract price for the earliest delivery date. During 2020, natural gas prices 
began the year at $2.12 per MMBtu and fell to a low of $1.48 per MMBtu at the end of June, before increasing 
to a high of $3.35 per MMBtu in late October and finishing the year at $2.54 per MMBtu.

Because we use the full-cost method of accounting, we perform a ceiling test quarterly that may be impacted 
by declining prices of oil and natural gas. The significant decline in oil and natural gas prices during 2020 caused us
to recognize full-cost ceiling impairments in each of the second, third and fourth quarters of 2020, and we may 
recognize further full-cost ceiling impairments in future periods. Such full-cost ceiling impairments reduce the book 
value of our net tangible assets, retained earnings and shareholders’ equity but do not impact our cash flows from 
operations, liquidity or capital resources. See “—We may be required to write down the carrying value of our proved 
properties under accounting rules, and these write-downs could adversely affect our financial condition.”

The prices we receive for our production, and the levels of our production, depend on numerous factors. These

factors include, but are not limited to, the following:

•

•

•

•

the domestic and foreign supply of, and demand for, oil and natural gas;

the actions of OPEC+ and state-controlled oil companies relating to oil price and production controls;

the prices and availability of competitors’ supplies of oil and natural gas;

the price and quantity of foreign imports;

  FORM 10-K PART I

 
 
46

MATADOR RESOURCES COMPANY 

•

the impact of U.S. dollar exchange rates;

• domestic and foreign governmental regulations and taxes;

• speculative trading of oil and natural gas futures contracts;

•

•

•

the availability, proximity and capacity of gathering, processing and transportation systems for oil, natural
gas and NGLs and gathering and disposal systems for produced water;

the availability of refining capacity;

the prices and availability of alternative fuel sources;

• weather conditions and natural disasters;

• political conditions in or affecting oil and natural gas producing regions or countries, including the 

United States, the Middle East, South America and Russia;

• domestic or global health concerns, including the outbreak of contagious or pandemic diseases, such

as COVID-19;

•

the continued threat of terrorism and the impact of military action and civil unrest;

• public pressure on, and legislative and regulatory interest within, federal, state and local governments to
stop, significantly limit or regulate oil and natural gas operations, including hydraulic fracturing activities;

•

•

•

the level of global oil and natural gas inventories and exploration and production activity;

the impact of energy conservation efforts;

technological advances affecting energy consumption; and

• overall worldwide economic conditions.

These factors make it difficult to predict future commodity price movements with any certainty. Substantially 
all of our oil and natural gas sales are made in the spot market or pursuant to contracts based on spot market prices 
and are not pursuant to long-term fixed price contracts. Further, oil and natural gas prices do not necessarily
fluctuate in direct relation to each other.

During the first quarter and through April 2020, the oil and natural gas industry witnessed an abrupt and

significant decline in oil prices from $63 per Bbl in early January to as low as ($38) per Bbl in late April. This sudden
decline in oil prices was attributable to two primary factors: (i) the precipitous decline in global oil demand resulting
from the worldwide spread of COVID-19 and (ii) a sudden, unexpected increase in global oil supply resulting
from actions initiated by Saudi Arabia to increase its oil production to world markets following the failure of efforts 
by OPEC+ to agree on coordinated production cuts at their March 6, 2020 meetings in Vienna, Austria. Primarily 
as a result of these unexpected events and the resulting declines in oil prices, we significantly modified our 2020 
operational plan.

Declines in oil or natural gas prices not only reduce our revenue, but could also reduce the amount of oil and

natural gas that we can produce economically and could reduce the amount we may borrow under our Credit 
Agreement. Should oil or natural gas prices decrease to economically unattractive levels and remain there for an 
extended period of time, we may elect to delay some of our exploration and development plans for our prospects, 
cease exploration or development activities on certain prospects due to the anticipated unfavorable economics 
from such activities or cease or delay further expansion of our midstream projects, each of which could have a 
material adverse effect on our business, financial condition, results of operations and reserves. In addition, such 

FORM 10-K PART I

2020 ANNUAL REPORT

47    

declines in commodity prices could cause a reduction in our borrowing base. If the borrowing base were to be less 
than the outstanding borrowings under our Credit Agreement at any time, we would be required to provide
additional collateral satisfactory in nature and value to the lenders to increase the borrowing base to an amount
sufficient to cover such excess or repay the deficit in equal installments over a period of six months.

We face numerous risks related to the COVID-19 global pandemic, which has had and is likely to continue to 
have a material adverse effect on our business, financial condition, results of operations and cash flows.

Since the beginning of 2020, the COVID-19 pandemic has spread across the globe and disrupted economies
and industries around the world, including the exploration and production and midstream businesses. The rapid
spread of COVID-19 has led to the implementation of various responses, including federal, state and local
government-imposed quarantines, shelter-in-place mandates, sweeping restrictions on travel and other public health
and safety measures, nearly all of which have materially reduced global demand for crude oil. The extent to which 
COVID-19 will continue to affect our business, financial condition, results of operations and cash flows and the 
demand for our production will depend on future developments, which are highly uncertain and cannot be predicted, 
including the duration or any recurrence of the outbreak and responsive measures, additional or modified
government actions, new information that may emerge concerning the severity of COVID-19 and the effectiveness 
of vaccines and other actions taken to contain COVID-19 or treat its impact now or in the future, among others.

Some impacts of the COVID-19 pandemic that could have an adverse effect on our business, financial condition, 

results of operations and cash flows include:

• significantly reduced prices for our oil production, resulting from a world-wide decrease in demand for

hydrocarbons and a resulting oversupply of existing production;

•

•

further decreases in the demand for our oil production, resulting from significantly decreased levels of
global, regional and local travel as a result, in part, of federal, state and local government-imposed
quarantines, including shelter-in-place mandates, enacted to slow the spread of COVID-19;

increased likelihood that we may, either voluntarily or as a result of third-party and regulatory mandates,
curtail or shut in production, resulting from depressed oil prices, lack of storage and other market or political
forces;

• significant decreases in the volumes of oil, natural gas and produced water that are transported, gathered,
processed or disposed of by San Mateo due to curtailed or shut-in production by Matador or other of
San Mateo’s customers;

•

•

•

•

•

increased costs associated with, or actual unavailability of, facilities for the storage of oil, natural gas and
NGL production in the markets in which we operate;

increased operational difficulties associated with the delivery of oil, natural gas and NGLs to end-markets,
resulting from pipeline and storage constraints;

the potential for the operations of the Black River Processing Plant and other critical midstream infrastructure 
to be adversely impacted by outbreaks of COVID-19 among the relevant workforce;

the potential for forced curtailment of oil and natural gas production by state governmental agencies,
resulting in a need to significantly curtail or shut in our production;

the potential for loss of leasehold interests due to the failure to produce oil and natural gas in paying
quantities as a result of significantly lower commodity prices, voluntary or forced curtailments or other
factors related to the misalignment of supply and demand, and the potential to incur significant costs
associated with litigation related to the foregoing;

   FORM 10-K PART I

 
 
48

MATADOR RESOURCES COMPANY 

•

•

•

•

•

increased third-party credit risk, including the risk that counterparties may not accept the delivery of
our oil, natural gas and NGL production, resulting from adverse market conditions, a lack of access to 
capital and storage or the failure of certain of our counterparties to continue as going concerns;

increased likelihood that counterparties to our existing agreements may seek to invoke force majeure
provisions to avoid the performance of contractual obligations, resulting from significantly adverse
market conditions;

the potential impact for delays in construction or increased costs related to midstream construction projects;

increased costs, staffing requirements and difficulties sourcing oilfield services related to social distancing
measures implemented in connection with federal, state or local government and voluntarily imposed
quarantines; and

increased legal and operational costs related to compliance with significant changes in federal, state and
local laws and regulations.

The COVID-19 outbreak continues to evolve, and the extent to which the outbreak may impact our business, 
financial condition, results of operations and cash flows will depend highly on future developments, which are very 
uncertain and cannot be predicted. Additionally, the extent and duration of the impact of the COVID-19 pandemic
on our stock price and that of our peer companies is uncertain and may make us look less attractive to investors. 
As a result, there may be a less active trading market for our common stock, our stock price may be more volatile
and our ability to raise capital could be impaired.

Our exploration, development, exploitation and midstream projects require substantial capital expenditures 
that may exceed our cash flows from operations and potential borrowings, and we may be unable to obtain 
needed capital on satisfactory terms, which could adversely affect our future growth.

Our exploration, development, exploitation and midstream activities are capital intensive. Our cash, operating 
cash flows, contributions from our joint venture partners and potential future borrowings, under our Credit Agreement, 
the San Mateo Credit Facility or otherwise, may not be sufficient to fund all of our future acquisitions or future 
capital expenditures. The rate of our future growth is dependent, at least in part, on our ability to access capital at
rates and on terms we determine to be acceptable.

Our cash flows from operations and access to capital are subject to a number of variables, including:

• our estimated proved oil and natural gas reserves;

•

•

•

•

In addition, the possible occurrence of future events, such as decreases in the prices of oil and natural gas, or 

extended periods of such decreased prices, terrorist attacks, wars or combat peace-keeping missions, financial
market disruptions, general economic recessions, oil and natural gas industry recessions, large company 
bankruptcies, accounting scandals, overstated reserves estimates by public oil companies and disruptions in the
financial and capital markets, has caused financial institutions, credit rating agencies and the public to more
closely review the financial statements, capital structures and spending and earnings of public companies, including 
energy companies. Such events have constrained the capital available to the energy industry in the past, and such
events or similar events could adversely affect our access to funding for our operations in the future.

If our revenues decrease as a result of lower oil and natural gas prices, operating difficulties, declines in reserves

or the value thereof or for any other reason, we may have limited ability to obtain the capital necessary to sustain 
our operations at current levels, further develop and exploit our current properties or invest in certain opportunities. 
Alternatively, to fund acquisitions, increase our rate of growth, expand our midstream operations, develop our 
properties or pay for higher service costs, we may decide to alter or increase our capitalization substantially through 
the issuance of debt or equity securities, the sale of production payments, the sale or joint venture of midstream
assets, oil and natural gas producing assets or leasehold interests, the sale or joint venture of oil and natural gas
mineral interests, the borrowing of funds or otherwise to meet any increase in capital spending. If we succeed in 
selling additional equity securities or securities convertible into equity securities to raise funds or make acquisitions, 
the ownership of our existing shareholders would be diluted, and new investors may demand rights, preferences or 
privileges senior to those of existing shareholders. If we raise additional capital through the issuance of new debt
securities or additional indebtedness, we may become subject to additional covenants that restrict our business
activities. If we are unable to raise additional capital from available sources at acceptable terms, our business, 
financial condition and results of operations could be adversely affected.

Our oil and natural gas reserves are estimated and may not reflect the actual volumes of oil and natural  
gas we will recover, and significant inaccuracies in these reserves estimates or underlying assumptions will 
materially affect the quantities and present value of our reserves.

The process of estimating accumulations of oil and natural gas is complex and inexact due to numerous inherent
uncertainties. This process relies on interpretations of available geological, geophysical, engineering and production
data. The extent, quality and reliability of this technical data can vary. This process also requires certain economic
assumptions related to, among other things, oil and natural gas prices, drilling and operating expenses, capital
expenditures, taxes and availability of funds. The accuracy of a reserves estimate is a function of:

•

•

•

•

the quality and quantity of available data;

the interpretation of that data;

the judgment of the persons preparing the estimate; and

the accuracy of the assumptions used.

The accuracy of any estimates of proved oil and natural gas reserves generally increases with the length of 

production history. Due to the limited production history of many of our properties, the estimates of future production
associated with these properties may be subject to greater variance to actual production than would be the case
with properties having a longer production history. As our wells produce over time and more data becomes available,
the estimated proved reserves will be redetermined on at least an annual basis and may be adjusted to reflect 
new information based upon our actual production history, results of exploration and development, prevailing oil 
and natural gas prices and other factors.

Actual future production, oil and natural gas prices, revenues, taxes, development expenditures, operating 

expenses and quantities of recoverable oil and natural gas most likely will vary from our estimates. It is possible that
future production declines in our wells may be greater than we have estimated. Any significant variance from our 
estimates could materially affect the quantities and present value of our reserves.

The calculated present value of future net revenues from our proved oil and natural gas reserves will not 
necessarily be the same as the current market value of our estimated oil and natural gas reserves.

It should not be assumed that the present value of future net cash flows included in this Annual Report is the
current market value of our estimated proved oil and natural gas reserves. As required by SEC rules and regulations,
the estimated discounted future net cash flows from proved oil and natural gas reserves are based on current
costs held constant over time without escalation and on commodity prices using an unweighted arithmetic average 
of first-day-of-the-month index prices, appropriately adjusted, for the 12-month period immediately preceding 
the date of the estimate. Actual future prices and costs may be materially higher or lower than the prices and costs
used for these estimates and will be affected by factors such as:

• actual prices we receive for oil and natural gas;

• actual costs and timing of development and production expenditures;

•

the amount and timing of actual production; and

• changes in governmental regulations or taxation.

In addition, the 10% discount factor that is required to be used to calculate discounted future net revenues for

reporting purposes under U.S. generally accepted accounting principles (“GAAP”) is not necessarily the most
appropriate discount factor based on the cost of capital in effect from time to time and risks associated with our 
business and the oil and natural gas industry in general.

Approximately 54% of our total proved reserves at December 31, 2020 consisted of undeveloped and 
developed non-producing reserves, and those reserves may not ultimately be developed or produced.

At December 31, 2020, approximately 54% of our total proved reserves were undeveloped and less than 1% of

our total proved reserves were developed non-producing. Our undeveloped and/or developed non-producing 
reserves may never be developed or produced, or such reserves may not be developed or produced within the time 
periods we have projected or at the costs we have estimated. SEC rules require that, subject to limited exceptions, 
proved undeveloped reserves may only be booked if they are related to wells scheduled to be drilled within five 
years after the date of booking. Delays in the development of our reserves or increases in costs to drill and develop
such reserves would reduce the present value of our estimated proved undeveloped reserves and future net
revenues estimated for such reserves, resulting in some projects becoming uneconomical and reducing our total
proved reserves. In addition, delays in the development of reserves or declines in the oil and/or natural gas prices 
used to estimate proved reserves in the future could cause us to have to reclassify a portion of our proved reserves
as unproved reserves. Any reduction in our proved reserves caused by the reclassification of undeveloped or 
developed non-producing reserves could materially affect our business, financial condition, results of operations
and cash flows.

Unless we replace our oil and natural gas reserves, our reserves and production will decline, which would 
adversely affect our business, financial condition, results of operations and cash flows.

The rate of production from our oil and natural gas properties declines as our reserves are depleted. Our future oil 

and natural gas reserves and production and, therefore, our income and cash flow are highly dependent on our 
success in efficiently developing and exploiting our current reserves and economically finding or acquiring additional 
oil and natural gas producing properties. We are currently focusing on increasing our production and reserves from 
the Delaware Basin, an area with intense competition and industry activity. As a result of this activity, we may have 
difficulty growing our current production or acquiring new properties in this area and may experience such difficulty 
in other areas in the future. During periods of low oil and/or natural gas prices, existing reserves may no longer be
economic, and it will become more difficult to raise the capital necessary to finance expansion activities. If we are
unable to replace our current and future production, our reserves will decrease, and our business, financial
condition, results of operations and cash flows would be adversely affected.

We may be required to write down the carrying value of our proved properties under accounting rules, and 
these write-downs could adversely affect our financial condition.

There is a risk that we will be required to write down the carrying value of our oil and natural gas properties
when oil or natural gas prices are low or are declining, as occurred in 2020. In addition, non-cash write-downs may
occur if we have:

• downward adjustments to our estimated proved reserves;

•

increases in our estimates of development costs; or

• deterioration in our exploration and development results.

We periodically review the carrying value of our oil and natural gas properties under full-cost accounting rules.
Under these rules, the net capitalized costs of oil and natural gas properties less related deferred income taxes may 
not exceed a cost center ceiling that is calculated by determining the present value, based on constant prices and 
costs projected forward from a single point in time, of estimated future after-tax net cash flows from proved 
reserves, discounted at 10%. If the net capitalized costs of our oil and natural gas properties less related deferred 
income taxes exceed the cost center ceiling, we must charge the amount of this excess to operations in the period 
in which the excess occurs. We may not reverse write-downs even if prices increase in subsequent periods. A 
write-down does not affect net cash flows from operating activities, liquidity or capital resources, but it does reduce
the book value of our net tangible assets, retained earnings and shareholders’ equity, and could lower the value of
our common stock.

Hedging transactions, or the lack thereof, may limit our potential gains and could result in financial losses.

To manage our exposure to price risk, we, from time to time, enter into hedging arrangements, using primarily

“costless collars” or “swaps” with respect to a portion of our future production. Costless collars provide us with 
downside price protection through the purchase of a put option, which is financed through the sale of a call option.
Because the call option proceeds are used to offset the cost of the put option, these arrangements are initially
“costless” to us. Three-way costless collars also provide us with downside price protection through the purchase
of a put option, but they also allow us to participate in price upside through the purchase of a call option. The
purchase of both the put option and call option are financed through the sale of a call option. Because the proceeds
from the call option sale are used to offset the cost of the purchased put and call options, these arrangements are 

  FORM 10-K PART I

 
 
52

MATADOR RESOURCES COMPANY 

also initially “costless” to us. In the case of a costless collar, the put option and the call option or options have
different fixed price components. In a swap contract, a floating price is exchanged for a fixed price over the specified 
period, providing downside price protection. The goal of these and other hedges is to lock in a range of prices in the 
case of collars or a fixed price in the case of swaps so as to mitigate price volatility and increase the predictability of
cash flows. These transactions limit our potential gains if oil, natural gas or NGL prices rise above the maximum price 
established by the call option or swap as applicable, and may offer protection if prices fall below the minimum 
price established by the put option or swap, as applicable, only to the extent of the volumes then hedged.

In addition, hedging transactions may expose us to the risk of financial loss in certain other circumstances, 
including instances in which our production is less than expected or the counterparties to our put and call option or
swap contracts fail to perform under the contracts. Disruptions in the financial markets could lead to sudden
changes in a counterparty’s liquidity, which could impair its ability to perform under the terms of the contracts. We 
are unable to predict sudden changes in a counterparty’s creditworthiness or ability to perform under contracts
with us. Even if we do accurately predict sudden changes, our ability to mitigate that risk may be limited depending 
upon market conditions.

Furthermore, there may be times when we have not hedged our production when, in retrospect, it would have
been advisable to do so. Decisions as to whether, at what price and what production volumes to hedge are difficult
and depend on market conditions and our forecast of future production and oil, natural gas and NGL prices, and 
we may not always employ the optimal hedging strategy. We may employ hedging strategies in the future that
differ from those that we have used in the past, and neither the continued application of our current strategies nor
our use of different hedging strategies may be successful. See Note 12 to the consolidated financial statements in
this Annual Report for a summary of our open derivative financial instruments at December 31, 2020.

An increase in the differential between the NYMEX or other benchmark prices of oil and natural gas and the 
wellhead price we receive for our production could adversely affect our business, financial condition, results 
of operations and cash flows.

The prices we receive for our oil and natural gas production often reflect a discount to the relevant benchmark 
prices, such as the WTI oil price or the NYMEX Henry Hub natural gas price. The difference between the benchmark 
price and the price we receive is called a differential. Increases in the differential between the benchmark price for
oil and natural gas and the wellhead price we receive could adversely affect our business, financial condition, results 
of operations and cash flows.

Over the past several years, these oil and natural gas basis differentials were volatile and widened at various 
times. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—General
Outlook and Trends” for additional information regarding the differentials. These wider oil and natural gas basis 
differentials were largely attributable to industry concerns regarding the near-term sufficiency of pipeline takeaway
capacity for oil, natural gas and NGL production in the Delaware Basin. If we do experience any interruptions with
takeaway capacity or NGL fractionation, our oil and natural gas revenues, business, financial condition, results of 
operations and cash flows could be adversely affected.

Although the completion of additional oil and natural gas pipeline capacity from West Texas to the Texas Gulf 
Coast and other end markets improved these price differentials in 2020, these price differentials could turn negative
and widen again in future periods. Should we experience future periods of negative pricing for natural gas as we did 
at certain times in 2020, we may temporarily shut in certain high gas-oil ratio wells and take other actions to mitigate 
the impact on our realized natural gas prices and results. We have limited oil basis hedges in place to mitigate our 
exposure to oil price differentials during 2021 and 2022, and we have no derivative contracts in place to mitigate our 
exposure to natural gas price differentials.

A component of our growth may come through acquisitions, and our failure to identify or complete future 
acquisitions successfully could reduce our earnings and hamper our growth.

We may be unable to identify properties for acquisition or to make acquisitions on terms that we consider 
economically acceptable. There is intense competition for acquisition opportunities in our industry. Competition
for acquisitions may increase the cost of, or cause us to refrain from, completing acquisitions. The pursuit and 
completion of acquisitions may be dependent upon, among other things, our ability to obtain debt and equity financing 
and, in some cases, regulatory approvals. Our ability to grow through acquisitions will require us to continue to
invest in operations and financial and management information systems and to attract, retain, motivate and effectively 
manage our employees. In addition, if we are not successful in identifying and acquiring properties, our earnings 
could be reduced and our growth could be restricted.

In addition, we may be unable to successfully integrate potential acquisitions into our existing operations. The 
inability to manage the integration of acquisitions effectively could reduce our focus on subsequent acquisitions and 
current operations and could negatively impact our results of operations and growth potential. Members of our
senior management team may be required to devote considerable amounts of time to the integration process, which 
will decrease the time they will have to manage our business.

Furthermore, our decision to acquire properties that are substantially different in operating or geologic characteristics

or geographic locations from areas with which our staff is familiar may impact our productivity in such areas. Our 
financial condition, results of operations and cash flows may fluctuate significantly from period to period as a result of 
the completion of significant acquisitions during particular periods.

We may engage in bidding and negotiation to complete successful acquisitions. We may be required to alter or
increase substantially our capitalization to finance these acquisitions through the use of cash on hand, the issuance of
debt or equity securities, the sale of production payments, the sale or joint venture of midstream assets or oil and
natural gas producing assets or acreage, the borrowing of funds or otherwise. Our Credit Agreement, the San Mateo 
Credit Facility and the indenture governing our outstanding senior notes include covenants limiting our ability
to incur additional debt. If we were to proceed with one or more acquisitions involving the issuance of our common
stock, our shareholders would suffer dilution of their interests.

We may purchase oil and natural gas properties or midstream assets with liabilities or risks that we did not 
know about or that we did not assess correctly, and, as a result, we could be subject to liabilities that could 
adversely affect our results of operations.

Before acquiring oil and natural gas properties or midstream assets, we assess the potential reserves, future oil
and natural gas prices, operating costs, potential environmental liabilities, condition of the assets, customer contracts 
and other factors relating to the properties or assets, as applicable. However, our review process is complex and 
involves many assumptions and estimates, and their accuracy is inherently uncertain. As a result, we may not 
discover all existing or potential problems associated with the properties or assets we buy. We may not become
sufficiently familiar with the properties or assets to assess fully their deficiencies and capabilities. We do not generally 
perform inspections on every well, property or asset, and we may not be able to observe mechanical and
environmental problems even when we conduct an inspection. The seller may not be willing or financially able to give 
us contractual protection against any identified problems, and we may decide to assume environmental and other 
liabilities in connection with properties or assets we acquire. If we acquire properties or assets with risks or liabilities 
we did not know about or that we did not assess correctly, our financial condition, results of operations and cash
flows could be adversely affected as we settle claims and incur cleanup costs related to these liabilities.

We may incur losses or costs as a result of title deficiencies in the properties in which we invest.

If an examination of the title history of a property that we have purchased reveals oil and natural gas leases or 

mineral interests have been purchased in error from a person who is not the owner of such interests or if the 
property has other title deficiencies, our interest would likely be worth less than what we paid or may be worthless. 
In such an instance, all or part of the amount paid for such oil and natural gas lease or mineral interest, as
well as all or part of any royalties paid pursuant to the terms of the lease prior to the discovery of the title defect, 
would be lost.

It is not our practice in all acquisitions of oil and natural gas leases or mineral interests, or undivided interests in

such interests, to undergo the expense of retaining lawyers to examine the title to the interest. Rather, in certain
acquisitions we rely upon the judgment of oil and natural gas brokers and/or landmen who perform the field work by
examining records in the appropriate governmental office before attempting to acquire a lease or mineral interest.

Prior to the drilling of an oil and natural gas well, however, it is standard industry practice for the operator of the
well to obtain a preliminary title review of the spacing unit within which the proposed well is to be drilled to ensure
there are no obvious deficiencies in title to the well. Frequently, as a result of such examinations, certain curative
work must be done to correct deficiencies in the marketability of the title, and such title review and curative work
entails expense, which may be significant and difficult to accurately predict. Our failure to cure any title defects
may adversely impact our ability to increase production and reserves. In the future, we may suffer a monetary loss 
from title defects or title failure. Additionally, unproved and unevaluated acreage has greater risk of title defects 
than developed acreage. If there are any title defects or defects in assignment of leasehold rights or mineral
interests in properties in which we hold an interest, we will suffer a financial loss that could adversely affect our
financial condition, results of operations and cash flows.

Our ability to complete dispositions of assets, or interests in assets, may be subject to factors beyond our 
control, and in certain cases we may be required to retain liabilities for certain matters.

From time to time, we may sell an interest in a strategic asset for the purpose of assisting or accelerating the 
asset’s development. In addition, we regularly review our property base for the purpose of identifying nonstrategic 
assets, the disposition of which would increase capital resources available for other activities and create 
organizational and operational efficiencies. Various factors could materially affect our ability to dispose of such
interests or nonstrategic assets or complete announced dispositions, including the receipt of approvals of 
governmental agencies or third parties and the identification of purchasers willing to acquire the interests or
purchase the nonstrategic assets on terms and at prices acceptable to us.

Sellers typically retain certain liabilities or indemnify buyers for certain pre-closing matters, such as matters of
litigation, environmental contingencies, royalty obligations and income taxes. The magnitude of any such retained
liability or indemnification obligation may be difficult to quantify at the time of the transaction and ultimately may
be material. Also, as is typical in divestiture transactions, third parties may be unwilling to release us from guarantees
or other credit support provided prior to the sale of the divested assets. As a result, after a divestiture, we may 
remain secondarily liable for the obligations guaranteed or supported to the extent that the buyer of the assets fails 
to perform these obligations.

RISKS RELATED TO OUR LIQUIDITY

We may not be able to generate sufficient cash to fund our capital expenditures, service all of our 
indebtedness and pay dividends to our shareholders, and we may be forced to take other actions to satisfy 
our obligations under applicable debt instruments, which may not be successful.

Our ability to make scheduled payments on or to refinance our indebtedness obligations depends on our

financial condition and operating performance, which are subject to prevailing economic and competitive conditions
and certain financial, business and other factors beyond our control. We may not be able to maintain a level 
of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on 
our indebtedness.

If our cash flows and capital resources are insufficient to fund debt service obligations, we may be forced to

reduce or delay investments and capital expenditures, sell assets, cease the payment of any dividends to our 
shareholders, seek additional capital or restructure or refinance indebtedness. Our ability to restructure or refinance
indebtedness will depend on the condition of the capital markets and our financial condition at such time. Any 
refinancing of indebtedness could be at higher interest rates and may require us to comply with more onerous 
covenants, which could further restrict business operations. The terms of existing or future debt instruments may 
restrict us from adopting some of these alternatives. In addition, any failure to make payments of interest and
principal on outstanding indebtedness on a timely basis would likely result in a reduction of our credit rating, which 
could harm our ability to incur additional indebtedness. In the absence of sufficient cash flows and capital resources,
we could face substantial liquidity problems and might be required to dispose of material assets or operations to 
meet debt service and other obligations. Our Credit Agreement, the San Mateo Credit Facility and the indenture 
governing our outstanding senior notes currently restrict our ability to dispose of assets and our use of the proceeds
from such disposition. We may not be able to consummate those dispositions, and the proceeds of any such 
disposition may not be adequate to meet any debt service obligations then due. These alternative measures may 
not be successful and may not permit us to meet scheduled debt service obligations, which could have a material
adverse effect on our financial condition and results of operations.

We may incur additional indebtedness, which could reduce our financial flexibility, increase interest expense 
and adversely impact our operations and our unit costs.

As of February 23, 2021, the maximum facility amount under the Credit Agreement was $1.5 billion, the
borrowing base was $900.0 million and our elected borrowing commitment was $700.0 million. Borrowings under
the Credit Agreement are limited to the lowest of the borrowing base, maximum facility amount and elected 
borrowing commitment (subject to compliance with the covenant noted below). At February 23, 2021, we had
available borrowing capacity of approximately $224.2 million under our Credit Agreement (after giving effect to
outstanding letters of credit). Our borrowing base is determined semi-annually by our lenders based primarily on the
estimated value of our existing and future oil and natural gas reserves, but both we and our lenders can request 
one unscheduled redetermination between scheduled redetermination dates. Our Credit Agreement is secured by
our interests in the majority of our oil and natural gas properties and contains covenants restricting our ability to 
incur additional indebtedness, sell assets, pay dividends and make certain investments. Since the borrowing base is 
subject to periodic redeterminations, if a redetermination resulted in a borrowing base that was less than our
borrowings under the Credit Agreement, we would be required to provide additional collateral satisfactory in nature
and value to the lenders to increase the borrowing base to an amount sufficient to cover such excess or repay the
deficit in equal installments over a period of six months. If we are required to do so, we may not have sufficient 
funds to fully make such repayments. The Credit Agreement requires us to maintain a debt to EBITDA ratio, which 
is defined as debt outstanding (net of up to $50.0 million of cash or cash equivalents), divided by a rolling four 
quarter EBITDA calculation, of 4.00 or less.

As of February 23, 2021, the facility amount under the San Mateo Credit Facility was $375.0 million, and

San Mateo had available borrowing capacity of approximately $43.0 million (after giving effect to outstanding letters 
of credit and subject to San Mateo’s compliance with the covenants noted below). The San Mateo Credit Facility
includes an accordion feature, which could expand the commitments of the lenders to up to $400.0 million.
The San Mateo Credit Facility is non-recourse with respect to Matador and its wholly-owned subsidiaries, but is 
guaranteed by San Mateo’s subsidiaries and secured by substantially all of San Mateo’s assets, including real 
property. The San Mateo Credit Facility requires San Mateo to maintain a debt to EBITDA ratio, which is defined as 
total consolidated funded indebtedness outstanding (as defined in the San Mateo Credit Facility) divided by a 
rolling four quarter EBITDA calculation, of 5.00 or less, subject to certain exceptions. The San Mateo Credit Facility 
also requires San Mateo to maintain an interest coverage ratio, which is defined as a rolling four quarter EBITDA
calculation divided by San Mateo’s consolidated interest expense for such period, of 2.50 or more. The San Mateo 
Credit Facility also restricts the ability of San Mateo to distribute cash to its members if San Mateo’s liquidity is
less than 10% of the lender commitments under the San Mateo Credit Facility. In addition to these restrictions, the 
San Mateo Credit Facility also contains covenants restricting San Mateo’s ability to incur additional indebtedness, 
sell assets, pay dividends and make certain investments.

In the future, subject to the restrictions in the indenture governing our outstanding senior notes and in other
instruments governing our other outstanding indebtedness (including our Credit Agreement and the San Mateo 
Credit Facility), we may incur significant amounts of additional indebtedness, including under our Credit Agreement
and the San Mateo Credit Facility, through the issuance of additional notes or otherwise, in order to develop our 
properties, fund acquisitions or invest in certain opportunities. Interest rates on such future indebtedness may be 
higher than current levels, causing our financing costs to increase accordingly.

A high level of indebtedness could affect our operations in several ways, including the following:

•

•

requiring a significant portion of our cash flows to be used for servicing our indebtedness;

increasing our vulnerability to general adverse economic and industry conditions;

• placing us at a competitive disadvantage compared to our competitors that are less leveraged and,

therefore, may be able to take advantage of opportunities that our level of indebtedness may prevent us
from pursuing;

•

restricting our ability to obtain additional financing in the future for working capital, capital expenditures,
acquisitions and general corporate or other purposes; and

•

increasing the risk that we may default on our debt obligations.

The borrowing base under our Credit Agreement is subject to periodic redetermination, and we are subject 
to interest rate risk under our Credit Agreement and the San Mateo Credit Facility.

The borrowing base under the Credit Agreement is determined semi-annually as of May 1 and November 1 by the

lenders based primarily on the estimated value of our proved oil and natural gas reserves at December 31 and 
June 30 of each year, respectively. We and the lenders may each request an unscheduled redetermination of the 
borrowing base once between scheduled redetermination dates. In addition, our lenders have the flexibility to 
reduce our borrowing base due to a variety of factors, some of which may be beyond our control. As of February 23, 
2021, our borrowing base was $900.0 million, our elected borrowing commitment was $700.0 million and we had 
$430.0 million in outstanding borrowings under, and approximately $45.8 million in outstanding letters of credit
issued pursuant to, the Credit Agreement. As of February 23, 2021, the maximum facility amount under the Credit
Agreement was $1.5 billion. Borrowings under the Credit Agreement are limited to the lowest of the borrowing

base, maximum facility amount and elected borrowing commitment (subject to compliance with the covenant
noted above). We could be required to repay a portion of any outstanding debt under the Credit Agreement to the 
extent that, after a redetermination, our outstanding borrowings at such time exceeded the redetermined borrowing
base. We may not have sufficient funds to make such repayments, which could result in a default under the 
terms of the Credit Agreement and an acceleration of the loans thereunder, requiring us to negotiate renewals, 
arrange new financing or sell significant assets, all of which could have a material adverse effect on our business
and financial results.

Our earnings are exposed to interest rate risk associated with borrowings under our Credit Agreement and the 

San Mateo Credit Facility. Borrowings under the Credit Agreement may be in the form of a base rate loan or a 
Eurodollar loan. If we borrow funds as a base rate loan, such borrowings will bear interest at a rate equal to the 
greatest of (i) the prime rate for such day, (ii) the Federal Funds Effective Rate (as defined in the Credit Agreement) 
on such day, plus 0.50%, and (iii) the daily adjusting LIBOR rate (as defined in the Credit Agreement), plus 1.0%, 
plus, in each case, an amount ranging from 0.25% to 1.25% per annum depending on the level of borrowings under
the Credit Agreement. If we borrow funds as a Eurodollar loan, such borrowings will bear interest at a rate equal
to (x) the reserve adjusted LIBOR rate (as defined in the Credit Agreement) plus (y) an amount ranging from 1.25% to 
2.25% per annum depending on the level of borrowings under the Credit Agreement. If we have outstanding
borrowings under our Credit Agreement and interest rates increase, so will our interest costs, which may have a
material adverse effect on our results of operations and financial condition.

Similarly, borrowings under the San Mateo Credit Facility may be in the form of a base rate loan or a Eurodollar

loan. If San Mateo borrows funds as a base rate loan, such borrowings will bear interest at a rate equal to the
greatest of (i) the prime rate for such day, (ii) the Federal Funds Effective Rate (as defined in the San Mateo Credit 
Facility) on such day, plus 0.50% and (iii) the Adjusted LIBO Rate (as defined in the San Mateo Credit Facility)
plus 1.0% plus, in each case, an amount ranging from 0.50% to 1.50% per annum depending on San Mateo’s
Consolidated Total Leverage Ratio (as defined in the San Mateo Credit Facility). If San Mateo borrows funds 
as a Eurodollar loan, such borrowings will bear interest at a rate equal to (x) the Adjusted LIBO Rate for the chosen
interest period plus (y) an amount ranging from 1.50% to 2.50% per annum depending on San Mateo’s
Consolidated Total Leverage Ratio. If San Mateo has outstanding borrowings under the San Mateo Credit Facility 
and interest rates increase, so will San Mateo’s interest costs, which may have a material adverse effect on
San Mateo’s results of operations and financial condition.

As noted above, under the Credit Agreement and the San Mateo Credit Facility, borrowings in the form of

Eurodollar loans accrue interest based on LIBOR. The use of LIBOR as a global reference rate is expected to be 
discontinued after 2021. Each of the Credit Agreement and the San Mateo Credit Facility specify that in the event 
that LIBOR cannot be determined or other conditions exist with respect to LIBOR, a replacement interest rate that 
gives due consideration to the then-prevailing market convention for determining a rate of interest for syndicated 
loans in the United States at such time may be established by the respective administrative agents, in consultation 
with us. If such an event occurs and we are unable to agree upon a replacement interest rate with our respective
administrative agents, we could be unable to make borrowings in the form of Eurodollar loans and would have to 
borrow funds at the higher base rate, which could increase our cost of capital. Furthermore, the overall financial 
market may be disrupted as a result of the phase-out or replacement of LIBOR. An increase in our cost of capital

The terms of the agreements governing our outstanding indebtedness may restrict our current and future 
operations, particularly our ability to respond to changes in business or to take certain actions.

Our Credit Agreement, the San Mateo Credit Facility and the indenture governing our senior notes contain,
and any future indebtedness we incur will likely contain, a number of restrictive covenants that impose significant 
operating and financial restrictions, including restrictions on our ability to engage in acts that may be in our best
long-term interest. One or more of these agreements include covenants that, among other things, restrict our 
ability to:

•

incur or guarantee additional debt or issue certain types of preferred stock;

• pay dividends on capital stock or redeem, repurchase or retire our capital stock or subordinated

indebtedness;

•

transfer or sell assets;

• make certain investments;

• create certain liens;

• enter into agreements that restrict dividends or other payments from our Restricted Subsidiaries (as defined

in the indenture) to us;

• consolidate, merge or transfer all or substantially all of our assets;

• engage in transactions with affiliates; and

• create unrestricted subsidiaries.

A breach of any of these covenants could result in an event of default under our Credit Agreement, the San Mateo

Credit Facility and the indenture governing our outstanding senior notes. For example, our Credit Agreement
requires us to maintain a debt to EBITDA ratio, which is defined as debt outstanding (net of up to $50 million of cash 
or cash equivalents) divided by a rolling four quarter EBITDA calculation, of 4.00 or less. Low oil and natural gas
prices or a decline in our oil or natural gas production may adversely impact our EBITDA, cash flows and debt levels,
and therefore our ability to comply with this covenant.

Similarly, the San Mateo Credit Facility requires San Mateo to meet a debt to EBITDA ratio, which is defined as
consolidated total funded indebtedness outstanding (as defined in the San Mateo Credit Facility) divided by a rolling 
four quarter EBITDA calculation, of 5.00 or less, subject to certain exceptions. The San Mateo Credit Facility also
requires San Mateo to maintain an interest coverage ratio, which is defined as a rolling four quarter EBITDA 
calculation divided by San Mateo’s consolidated interest expense, of 2.50 or more. Lower revenues as a result of
less volumes than anticipated, or otherwise, or an increase in interest rates may adversely impact San Mateo’s 
EBITDA and interest expense, and therefore San Mateo’s ability to comply with these covenants. The San Mateo 
Credit Facility also restricts the ability of San Mateo to distribute cash to its members if San Mateo’s liquidity is
less than 10% of the lender commitments under the San Mateo Credit Facility.

Upon the occurrence of an event of default, all amounts outstanding under the applicable debt agreements could

be declared to be immediately due and payable and all applicable commitments to extend further credit could be
terminated. If indebtedness under our Credit Agreement, the San Mateo Credit Facility or the indenture governing
our outstanding senior notes is accelerated, there can be no assurance that we will have sufficient assets to
repay such indebtedness. The operating and financial restrictions and covenants in these debt agreements and any 
future financing agreements could adversely affect our ability to finance future operations or capital needs or 
to engage in other business activities.

Our credit rating may be downgraded, which could reduce our financial flexibility, increase interest expense 
and adversely impact our operations.

In March 2020, our corporate credit rating from Standard & Poor’s Rating Services was downgraded from “B+”
to “B-” and our corporate credit rating from Moody’s Investors Service was downgraded from “B1” to “B3.” The 
downgrades resulted in significant part due to the sudden decline in oil prices in early 2020. Moody’s Investor 
Services upgraded our corporate credit rating in July 2020 to “B2.” As of February 23, 2021, our corporate credit 
ratings from Standard & Poor’s Rating Services and Moody’s Investors Service remained “B-” and “B2,” 
respectively. We cannot assure you that our credit ratings will remain in effect for any given period of time or that a 
rating will not be lowered or withdrawn entirely by a rating agency if, in its judgment, circumstances so warrant. Any 
future downgrade could increase the cost of any indebtedness incurred in the future.

Any increase in our financing costs resulting from a credit rating downgrade could adversely affect our ability to
obtain additional financing in the future for working capital, capital expenditures, additional letters of credit or other 
credit support we may be required to provide to counterparties, acquisitions and general corporate or other 
purposes. If a credit rating downgrade were to occur at a time when we were experiencing significant working
capital requirements or otherwise lacked liquidity, our results of operations could be materially adversely affected.

The payment of dividends will be at the discretion of our Board of Directors and subject to numerous 
factors, and we do not presently intend to repurchase any shares of our common stock.

On February 22, 2021, we declared our first quarterly dividend of $0.025 per share, and we intend to continue 
to pay a quarterly dividend in the future pursuant to a dividend policy adopted by our Board of Directors. However, 
the payment and amount of future dividend payments, if any, are subject to declaration by our Board of Directors.
Such payments will depend on, among other things, our available cash, earnings, financial condition, capital
requirements, level of indebtedness, stock price, statutory and contractual restrictions applicable to the payment of 
dividends and other considerations that our Board of Directors deems relevant. Cash dividend payments in the 
future may only be made out of legally available funds, and, if we experience substantial losses, such funds may
not be available.

We do not presently intend to repurchase any shares of our common stock. Certain covenants in our Credit 

Agreement and the indenture governing our outstanding senior notes may limit our ability to pay dividends or 
repurchase shares of our common stock. Accordingly, you may have to sell some or all of your common stock in
order to generate cash flow from your investment, and there is no guarantee that the price of our common stock
will exceed the price you paid. We are under no obligation to make dividend payments on our common stock 
and may cease such payments at any time in the future. Any elimination of or downward revision in our dividend 
payout could have a material adverse effect on our stock price.

RISKS RELATED TO OUR OPERATIONS

Drilling for and producing oil and natural gas are highly speculative and involve a high degree of 
operational and financial risk, with many uncertainties that could adversely affect our business.

Exploring for and developing hydrocarbon reserves involves a high degree of operational and financial risk, which 

precludes us from definitively predicting the costs involved and time required to reach certain objectives. Our
drilling locations are in various stages of evaluation, ranging from locations that are ready to drill to locations that will 
require substantial additional interpretation and approvals before they can be drilled. The budgeted costs of
planning, drilling, completing and operating wells may be exceeded and such costs can increase significantly due to
various complications that may arise during drilling, completion and operation. Before a well is spud, we may incur
significant geological, geophysical and land costs, including seismic costs, which are incurred whether or not a well 
eventually produces commercial quantities of hydrocarbons, or is drilled at all. Exploration wells bear a much
greater risk of loss than development wells. The analogies we draw from available data from other wells, more fully
explored locations or producing fields may not be applicable to our drilling locations. If our actual drilling and
development costs are significantly more than our estimated costs, we may not be able to continue our operations 
as proposed and could be forced to modify our drilling plans accordingly.

If we decide to drill a certain location, there is a risk that no commercially productive oil or natural gas reservoirs

will be found or produced. We may drill or participate in new wells that are not productive. We may drill or
participate in wells that are productive, but that do not produce sufficient net revenues to return a profit after drilling, 
operating and other costs. There is no way to affirmatively determine in advance of drilling and testing whether 
any particular location will yield oil or natural gas in sufficient quantities to recover exploration, drilling and completion 
costs or to be economically viable. Even if sufficient amounts of oil or natural gas exist, we may damage the
potentially productive hydrocarbon-bearing formation or experience mechanical difficulties while drilling or completing
the well, resulting in a reduction in production and reserves from, or abandonment of, the well. The productivity 
and profitability of a well may be negatively affected by a number of additional factors, including the following:

• general economic and industry conditions, including the prices received for oil and natural gas;

• shortages of, or delays in, obtaining equipment, including hydraulic fracturing equipment, and

qualified personnel;

• potential drainage of oil and natural gas from our properties by adjacent operators;

•

•

the existence or magnitude of faults or unanticipated geological features;

loss of or damage to oilfield development and service tools;

• accidents, equipment failures or mechanical problems;

•

•

title defects of the underlying properties;

increases in severance taxes;

• adverse weather conditions that delay drilling activities or cause producing wells to be shut in;

• domestic and foreign governmental regulations; and

• proximity to and capacity of gathering, processing and transportation facilities.

FORM 10-K PART I

2020 ANNUAL REPORT

61    

Furthermore, our exploration and production operations involve using some of the latest drilling and completion 
techniques developed by us, other operators and service providers. Risks that we face while drilling and completing 
horizontal wells include, but are not limited to, the following:

•

landing our wellbore in the desired drilling zone;

• staying in the desired drilling zone while drilling horizontally through the formation;

•

•

running our casing the entire length of the wellbore;

fracture stimulating the planned number of stages;

• drilling out the plugs between stages following hydraulic fracturing operations; and

• being able to run tools and other equipment consistently through the horizontal wellbore.

Each of these risks is magnified in wells with longer laterals. In 2020, 74% of the operated wells we turned to sales 

had lateral lengths of two miles. In 2021, we anticipate that 98% of the operated wells we turn to sales should 
have lateral lengths of two miles or greater. If we do not drill productive and profitable wells in the future, our business, 
financial condition, results of operations, cash flows and reserves could be materially and adversely affected.

Our operations are subject to operational hazards and risks, which could result in significant damages and 
the loss of revenue.

There are numerous operational hazards inherent in oil and natural gas exploration, development, production, 

gathering, transportation and processing, including:

• natural disasters;

• adverse weather conditions;

• domestic or global health concerns, including the outbreak of contagious or pandemic diseases, such as

COVID-19;

•

loss of drilling fluid circulation;

• blowouts where oil or natural gas flows uncontrolled at a wellhead;

• cratering or collapse of the formation;

• pipe or cement leaks, failures or casing collapses;

• damage to pipelines, processing plants and disposal wells and associated facilities;

• fires or explosions;

•

releases of hazardous substances or other waste materials that cause environmental damage;

• pressures or irregularities in formations; and

• equipment failures or accidents.

In addition, there is an inherent risk of incurring significant environmental costs and liabilities in the performance of our 

operations and services, some of which may be material, due to our handling of petroleum hydrocarbons and wastes,
our emissions to air and water, the underground injection or other disposal of wastes, the use of hydraulic fracturing 
fluids and historical industry operations and waste disposal practices. Any of these or other similar occurrences could 
result in the disruption or impairment of our operations, substantial repair costs, personal injury or loss of human life, 
significant damage to property, environmental pollution and substantial revenue losses. The location of our wells, 
gathering systems, pipelines and other facilities near populated areas, including residential areas, commercial business
centers and industrial sites, could significantly increase the level of damages resulting from these risks.

      FORM 10-K PART I

 
 
62

MATADOR RESOURCES COMPANY  

There are also significant risks associated with the operation of cryogenic natural gas processing plants such as 

the Black River Processing Plant owned by San Mateo and operated by us. Natural gas and NGLs are volatile and 
explosive and may include carcinogens. Damage to or improper operation of the Black River Processing Plant could 
result in an explosion or the discharge of toxic gases, which could result in significant damage claims, interrupt 
a revenue source and prevent us from processing some or all of the natural gas produced from our wells or third-
party wells located in nearby asset areas. Furthermore, if we were unable to process such natural gas, we may be
forced to flare natural gas from, or shut in, the affected wells for an indefinite period of time.

In addition, San Mateo’s gathering, processing and transportation assets connect to other pipelines or facilities 

owned and operated by unaffiliated third parties. The continuing operation of, and our continuing access to, such 
third-party pipelines, processing facilities and other midstream facilities is not within our control. These pipelines, 
plants, salt water disposal wells and other midstream facilities may become unavailable because of testing,
turnarounds, line repair, maintenance, reduced operating pressure, lack of operating capacity, regulatory requirements 
and curtailments of receipt or deliveries due to insufficient capacity or because of damage from severe weather
conditions or other operational issues. In addition, if San Mateo’s costs to access and transport on these third-party
pipelines significantly increase, its profitability could be reduced. If any such increase in costs occurs, if any of
these pipelines or other midstream facilities become unable to receive, transport, process or dispose of product, or 
if the volumes San Mateo gathers, processes or transports do not meet the product quality requirements of such 
pipelines or facilities, our and San Mateo’s revenues and cash flows could be adversely affected.

Insurance against all operational risks is not available to us.

Insurance against all operational risks is not available to us. We are not fully insured against all risks, including 

development and completion risks that are generally not recoverable from third parties or insurance. Pollution
and environmental risks generally are not fully insurable. In addition, we may elect not to obtain insurance if we 
believe that the cost of available insurance is excessive relative to the perceived risks presented. Losses could,
therefore, occur for uninsurable or uninsured risks or in amounts in excess of existing insurance coverage. 
Moreover, insurance may not be available in the future at commercially reasonable prices or on commercially
reasonable terms. Changes in the insurance markets due to various factors may make it more difficult for us
to obtain certain types of coverage in the future. As a result, we may not be able to obtain the levels or types of
insurance we would have otherwise obtained prior to these market changes, and the insurance coverage we
do obtain may not cover certain hazards or all potential losses that are currently covered, and may be subject to 
large deductibles. Losses and liabilities from uninsured and underinsured events and delays in the payment of 
insurance proceeds could have a material adverse effect on our business, financial condition, results of operations 
and cash flows.

Because our reserves and production are concentrated in a few core areas, problems in production and 
markets relating to a particular area could have a material impact on our business.

Almost all of our current oil and natural gas production and our proved reserves are attributable to our properties 

in the Delaware Basin in Southeast New Mexico and West Texas, the Eagle Ford shale in South Texas and the 
Haynesville shale in Northwest Louisiana. In recent years, the Delaware Basin has become an area of increasing
focus for us, and approximately 90% of our total oil and natural gas production for 2020 was attributable to our 
properties in the Delaware Basin. Since 2016, the vast majority of our capital expenditures have been allocated to 
the Delaware Basin. We expect that substantially all of our capital expenditures in 2021 will continue to be in the 
Delaware Basin, with the exception of amounts allocated to limited operations in our South Texas and Haynesville 
shale positions to maintain and extend leases and to participate in certain non-operated well opportunities.

FORM 10-K PART I

2020 ANNUAL REPORT

63    

The industry focus on the Delaware Basin may adversely impact our ability to gather, transport and process our 
oil and natural gas production due to significant competition for access to gathering systems, pipelines, processing 
and refinery facilities and oil, condensate and produced water trucking operations. For example, infrastructure
constraints have in the past required, and may in the future require, us to flare natural gas occasionally, decreasing 
the volumes sold from our wells. Due to the concentration of our operations, we may be disproportionately exposed
to the impact of delays or interruptions of production from our wells in our operating areas caused by transportation
capacity constraints or interruptions, curtailment of production, availability of equipment, facilities, personnel or 
services, significant governmental regulation, natural disasters, adverse weather conditions or plant closures for
scheduled maintenance. Due to our concentration of properties in the Delaware Basin, we are also particularly
exposed to any differential between benchmark prices of oil and natural gas and the wellhead price we receive for 
our production. See “—Risks Related to our Financial Condition—An increase in the differential between the
NYMEX or other benchmark prices of oil and natural gas and the wellhead price we receive for our production could 
adversely affect our business, financial condition, results of operations and cash flows.”

Our operations may also be adversely affected by weather conditions and events such as hurricanes, tropical 

storms and inclement winter weather, resulting in delays in drilling and completions, damage to facilities and 
equipment and the inability to receive equipment or access personnel and products at affected job sites in a timely 
manner. For example, in recent years, including in February 2021, the Delaware Basin has experienced periods
of severe winter weather that impacted many operators. In particular, weather conditions and freezing temperatures
have resulted in shut-ins of producing wells, power outages, curtailments in trucking, delays in drilling and 
completion of wells and other production constraints. Certain areas of the Delaware Basin have also experienced 
periods of severe flooding that impacted our operations as well as many other operators in the area, resulting
in delays in drilling, completing and initiating production on certain wells. As we continue to focus our operations
on the Delaware Basin, we may increasingly face these and other challenges posed by severe weather.

Similarly, certain areas of the Eagle Ford shale play are prone to severe tropical weather, such as Hurricane
Harvey in August 2017, which caused many operators to shut in production. We experienced minor operational
interruptions in our central and eastern Eagle Ford operations as a result of Hurricane Harvey, although future
storms might cause more severe damage and interruptions or disrupt our ability to market production from our
operating areas, including the Eagle Ford shale and the Delaware Basin.

Due to the concentrated nature of our portfolio of properties, a number of our properties could experience any 
of the same conditions at the same time, resulting in a relatively greater impact on our results of operations than they 
might have on other companies that have a more diversified portfolio of properties. For example, our operations in 
the Delaware Basin are subject to particular restrictions on drilling activities based on environmental sensitivities and 
requirements and potash mining operations. Such delays, interruptions or restrictions could have a material adverse
effect on our financial condition, results of operations and cash flows.

There is no guarantee that we will be successful in optimizing our spacing, drilling and completions 
techniques in order to maximize our rate of return, cash flow from operations and shareholder value.

As we accumulate and process geological and production data, we attempt to create a development plan, 
including well spacing and completion design, that maximizes our rate of return, cash flow from operations and
shareholder value. Due to many factors, however, including some beyond our control, there is no guarantee that 
we will be able to find the optimal plan. Future drilling and completion efforts may impact production from existing 
wells, and parent-child well effects may impact future well productivity as a result of timing, spacing proximity 
or other factors. If we are unable to design and implement an effective spacing, drilling and completions strategy,
it may have a material adverse effect on our financial condition, results of operations and cash flows.

Certain of our properties are in areas that may have been partially depleted or drained by offset wells, and 
certain of our wells may be adversely affected by actions other operators may take when drilling, 
completing or operating wells that they own.

Certain of our properties are in areas that may have already been partially depleted or drained by earlier offset 
drilling. The owners of leasehold interests adjoining any of our properties could take actions, such as drilling and
completing additional wells, which could adversely affect our operations. When a new well is completed and 
produced, the pressure differential in the vicinity of the well causes the migration of reservoir fluids toward the new
wellbore (and potentially away from existing wellbores). As a result, the drilling and production of these potential 
locations could cause a depletion of our proved reserves and may inhibit our ability to further develop our proved 
reserves. In addition, completion operations and other activities conducted on adjacent or nearby wells could cause
production from our wells to be shut in for indefinite periods of time, could result in increased lease operating 
expenses and could adversely affect the production and reserves from our wells after they re-commence production.
We have no control over the operations or activities of offsetting operators.

Multi-well pad drilling may result in volatility in our operating results.

We utilize multi-well pad drilling where practical. Because wells drilled on a pad are not produced until other wells 

being drilled on the pad at the same time are drilled and completed and the drilling rig is moved from the location, 
multi-well pad drilling delays the commencement of production from wells drilled on a given pad, which may cause
volatility in our operating results. In addition, problems affecting one well could adversely affect production from
other wells on the same pad. As a result, multi-well pad drilling can cause delays in the scheduled commencement 
of production or interruptions in ongoing production. Additionally, infrastructure expansion, including more 
complex facilities and takeaway capacity, could become challenging in project development areas. Managing capital
expenditures for infrastructure expansion could cause economic constraints when considering design capacity.

The unavailability or high cost of drilling rigs, completion equipment and services, supplies and personnel, 
including hydraulic fracturing equipment and personnel, could adversely affect our ability to establish  
and execute exploration and development plans within budget and on a timely basis, which could have a 
material adverse effect on our financial condition, results of operations and cash flows.

Shortages or the high cost of drilling rigs, completion equipment and services, personnel or supplies, including
sand and other proppants, could delay or adversely affect our operations. When drilling activity in the United States 
or a particular operating area increases, associated costs typically also increase, including those costs related to
drilling rigs, equipment, supplies, including sand and other proppants, and personnel and the services and products 
of other industry vendors. These costs may increase, and necessary equipment, supplies and services may become 
unavailable to us at economical prices. Should this increase in costs occur, we may delay drilling or completion 
activities, which may limit our ability to establish and replace reserves, or we may incur these higher costs, which
may negatively affect our business, financial condition, results of operations and cash flows. In addition, should
oil and natural gas prices decline, third-party service providers may face financial difficulties and be unable to provide 
services. A reduction in the number of service providers available to us may negatively impact our ability to retain
qualified service providers, or obtain such services at costs acceptable to us.

In addition, the demand for hydraulic fracturing services from time to time exceeds the availability of fracturing
equipment and crews across the industry and in certain operating areas in particular. The accelerated wear and tear
of hydraulic fracturing equipment due to its deployment in unconventional oil and natural gas fields characterized
by longer lateral lengths and larger numbers of fracturing stages could further amplify such an equipment and crew
shortage. If demand for fracturing services were to increase or the supply of fracturing equipment and crews
were to decrease, higher costs or delays in procuring these services could result, which could adversely affect our 
business, financial condition, results of operations and cash flows.

If we are unable to acquire adequate supplies of water for our drilling and hydraulic fracturing operations or 
are unable to dispose of the water we use at a reasonable cost and pursuant to applicable environmental 
rules, our ability to produce oil and natural gas commercially and in commercial quantities could be impaired.

We use a substantial amount of water in our drilling and hydraulic fracturing operations. Our inability to obtain
sufficient amounts of water at reasonable prices, or treat and dispose of water after drilling and hydraulic fracturing,
could adversely impact our operations. In recent years, Southeast New Mexico and West Texas have experienced 
severe drought. As a result, we may experience difficulty in securing the necessary volumes of water for our 
operations. Moreover, the imposition of new environmental initiatives and regulations could include restrictions on 
our ability to conduct certain operations such as (i) hydraulic fracturing, including, but not limited to, the use of
fresh water in such operations, or (ii) disposal of waste, including, but not limited to, the disposal of produced water, 
drilling fluids and other wastes associated with the exploration, development and production of oil and natural gas. 
Furthermore, future environmental regulations and permitting requirements governing the withdrawal, storage and 
use of surface water or groundwater necessary for hydraulic fracturing of wells could increase operating costs 
and cause delays, interruptions or termination of operations, the extent of which cannot be predicted, and all of
which could have an adverse effect on our business, financial condition, results of operations and cash flows.

If regulatory changes prevent our ability to continue to pool wells in the manner we have been, it could 
have a material adverse impact on our future production results.

In Texas, allocation wells allow an operator to drill a horizontal well under two or more leaseholds that are not 
pooled or across multiple existing pooled units. In New Mexico, operators are able to pool multiple spacing units in 
order to drill a single horizontal well across several leaseholds. We are active in drilling and producing both allocation 
wells in Texas and pooled spacing unit wells in New Mexico. If there are regulatory changes with regard to such wells, 
the applicable state agency denies or significantly delays the permitting of such wells, legislation is enacted that 
negatively impacts the current process under which such wells are permitted or litigation challenges the regulatory 
schemes pursuant to which such wells are permitted, it could have an adverse impact on our ability to drill long
horizontal lateral wells on some of our leases, which in turn could have a material adverse impact on our anticipated 
future production.

Construction of midstream projects subjects us to risks of construction delays, cost over-runs, limitations on 
our growth and negative effects on our financial condition, results of operations, cash flows and liquidity.

From time-to-time, we, through San Mateo or otherwise, plan and construct midstream projects, some of which

may take a number of months before commercial operation, such as construction of oil, natural gas and produced
water gathering systems, construction of natural gas processing plants, drilling of commercial salt water disposal 
wells and construction of related facilities. These projects are complex and subject to a number of factors beyond 
our control, including delays from third-party landowners, the permitting process, government and regulatory 
approval, compliance with laws, unavailability of materials, labor disruptions, environmental hazards, financing,
accidents, weather and other factors. Any delay in the completion of these projects could have a material 
adverse effect on our business, results of operations, liquidity and financial condition. The construction of salt water
disposal facilities, pipelines and gathering and processing facilities requires the expenditure of significant amounts 
of capital, which may exceed our estimated costs. Estimating the timing and expenditures related to these 
development projects is very complex and subject to variables that can significantly increase expected costs. Should
the actual costs of these projects exceed our estimates, our liquidity and financial condition could be adversely 
affected. This level of development activity requires significant effort from our management and technical personnel
and places additional requirements on our financial resources and internal financial controls. We may not have the 
ability to attract and/or retain the necessary number of personnel with the skills required to bring complicated projects 
to successful conclusions.

Our identified drilling locations are scheduled over several years, making them susceptible to uncertainties 
that could materially alter the occurrence or timing of their drilling.

Our management team has identified and scheduled drilling locations in our operating areas over a multi-year 
period. Our ability to drill and develop these locations depends on a number of factors, including oil and natural gas 
prices, assessment of risks, costs, drilling results, reservoir heterogeneities, the availability of equipment and capital, 
approval by regulators, lease terms, seasonal conditions and the actions of other operators. Additionally, as lateral 
lengths greater than one mile become increasingly common in the Delaware Basin, we will have to cooperate with
other operators to ensure that our acreage is included in drilling units or otherwise developed. In January 2021, the 
Biden administration issued the Biden Administration Federal Lease Orders. The impact of these federal actions
remains unclear, and if the restrictions do not lapse, or other limitations or prohibitions become effective, our drilling 
locations on federal lands may not be drilled as scheduled. The final determination on whether to drill any of the
identified locations will be dependent upon the factors described elsewhere in this Annual Report as well as, to 
some degree, the results of our drilling activities with respect to our established drilling locations. Because of these
uncertainties, we do not know if the drilling locations we have identified will be drilled within our expected
timeframe, or at all, or if we will be able to economically produce hydrocarbons from these or any other potential 
drilling locations. Our actual drilling activities may be materially different from our current expectations, which could
adversely affect our business, financial condition, results of operations and cash flows.

Certain of our unproved and unevaluated acreage is subject to leases that will expire over the next several 
years unless production is established on units containing the acreage.

At December 31, 2020, we had leasehold interests in approximately 34,800 net acres across all of our areas of

interest that are not currently held by production and are subject to leases with primary or renewed terms that
expire prior to 2026. Unless we establish and maintain production, generally in paying quantities, on units containing 
these leases during their terms or we renew such leases, these leases will expire. The cost to renew such leases
may increase significantly, and we may not be able to renew such leases on commercially reasonable terms or
at all. In addition, on certain portions of our acreage, third-party leases, or top leases, may have been taken and
could become immediately effective if our leases expire. If our leases expire or we are unable to renew such leases,
we will lose our right to develop the related properties. As such, our actual drilling activities may materially differ 
from our current expectations, which could adversely affect our business, financial condition, results of operations
and cash flows.

The 2-D and 3-D seismic data and other advanced technologies we use cannot eliminate exploration risk, 
which could limit our ability to replace and grow our reserves and materially and adversely affect our 
results of operations and cash flows.

We employ visualization and 2-D and 3-D seismic images to assist us in exploration and development activities 
where applicable. These techniques only assist geoscientists in identifying subsurface structures and hydrocarbon 
indicators and do not allow the interpreter to know conclusively if hydrocarbons are present or economically 
producible. We could incur losses by drilling unproductive wells based on these technologies. Furthermore, the
acquisition of seismic and geological data can be expensive and require the incurrence of various risks and
liabilities, and we may not be able to license or obtain such data at an acceptable cost. Poor results from our 
exploration and development activities could limit our ability to replace and grow reserves and adversely affect 
our business, financial condition, results of operations and cash flows.

RISKS RELATED TO THIRD PARTIES

Financial difficulties encountered by our oil and natural gas purchasers, third-party operators or other third 
parties could decrease our cash flows from operations and adversely affect the exploration and development 
of our prospects and assets.

We derive most of our revenues from the sale of our oil, natural gas and NGLs to unaffiliated third-party 

purchasers, independent marketing companies and midstream companies. We are also subject to credit risk due to 
the concentration of our oil and natural gas receivables with several significant customers. For the years ended 
December 31, 2020, 2019 and 2018, we had two, two and four significant purchasers, respectively, that collectively 
accounted for approximately 65%, 67% and 60%, respectively, of our total oil, natural gas and NGL revenues.
We cannot ensure that we will continue to have ready access to suitable markets for our future production. If we
lost one or more of these customers and were unable to sell our production to other customers on terms we
consider acceptable, it could materially and adversely affect our business, financial condition, results of operations
and cash flows. Furthermore, we cannot predict the extent to which counterparties’ businesses would be impacted
if oil and natural gas prices decline, such prices remain depressed for a sustained period of time or other conditions 
in our industry were to deteriorate. Any delays in payments from our purchasers caused by financial problems
encountered by them could have an immediate negative effect on our results of operations and cash flows.

In addition to credit risk related to purchasers of our production, we also face credit risk through receivables from 

joint interest owners on properties we operate. Joint interest receivables arise from billing entities that own partial
interests in the wells we operate. These entities participate in our wells primarily based on their ownership in leases 
on which we drill. We are generally unable to control which co-owners participate in our wells. Liquidity and cash
flow problems encountered by our joint interest owners or the third-party operators of our non-operated properties 
may prevent or delay the drilling of a well or the development of a project. Our joint interest owners may be 
unwilling or unable to pay their share of the costs of projects as they become due. In the case of a farmout party, 
we would have to find a new farmout party or obtain alternative funding in order to complete the exploration and
development of the prospects subject to a farmout agreement. In the case of a working interest owner, we could be 
required to pay the working interest owner’s share of the project costs. If we are not able to obtain the capital
necessary to fund either of these contingencies or find a new farmout party, our results of operations and cash flows 
could be negatively affected.

The marketability of our production is dependent upon oil, natural gas and NGL gathering, processing and 
transportation facilities, and the unavailability of satisfactory oil, natural gas and NGL gathering, processing 
and transportation arrangements could have a material adverse effect on our revenue.

The unavailability of satisfactory oil, natural gas and NGL gathering, processing and transportation arrangements 

may hinder our access to oil, natural gas and NGL markets or delay production from our wells. The availability of
a ready market for our oil, natural gas and NGL production depends on a number of factors, including the demand
for, and supply of, oil, natural gas and NGLs and the proximity of reserves to pipelines and terminal facilities.
Our ability to market our production depends in substantial part on the availability and capacity of gathering systems, 
pipelines, processing facilities and oil and condensate trucking operations. Such systems and operations include
those of San Mateo, as well as other systems and operations owned and operated by third parties. The continuing
operation of, and our continuing access to, third-party systems and operations is outside our control. Regardless 
of who operates the midstream systems or operations upon which we rely, our failure to obtain these services on
acceptable terms could materially harm our business. In addition, certain of these gathering systems, pipelines 
and processing facilities, particularly in the Delaware Basin, may be outdated or in need of repair and subject to higher 

      FORM 10-K PART I 

 
 
68

MATADOR RESOURCES COMPANY  

rates of line loss, failure and breakdown. Furthermore, such facilities may become unavailable because of testing,
turnarounds, line repair, maintenance, reduced operating pressure, lack of operating capacity, regulatory 
requirements and curtailments of receipt or deliveries due to insufficient capacity or because of damage from
severe weather conditions or other operational issues.

We may be required to shut in wells for lack of a market or because of inadequate or unavailable pipelines, 

gathering systems, processing facilities or trucking capacity. If that were to occur, we would be unable to
realize revenue from those wells until production arrangements were made to deliver our production to market. 
Furthermore, if we were required to shut in wells we might also be obligated to pay shut-in royalties to certain
mineral interest owners in order to maintain our leases. In addition, if we are unable to market our production we
may be required to flare natural gas, which would decrease the volumes sold from our wells, and, in certain 
circumstances, would require us to pay royalties on such flared natural gas.

The disruption of our own or third-party facilities due to maintenance, weather or other factors could negatively
impact our ability to market and deliver our oil, natural gas and NGLs. If our costs to access and transport on these
pipelines significantly increase, our profitability could be reduced. Third parties control when or if their facilities 
are restored and what prices will be charged. In the past, we have experienced pipeline and natural gas processing 
interruptions and capacity and infrastructure constraints associated with natural gas production, which has,
among other things, required us to flare natural gas occasionally. While we have entered into natural gas
processing and transportation agreements covering the anticipated natural gas production from a significant portion
of our Delaware Basin acreage in Southeast New Mexico and West Texas, no assurance can be given that these
agreements will alleviate these issues completely, and we may be required to pay deficiency payments under 
such agreements if we do not meet the gathering or processing commitments, as applicable. We may experience 
similar interruptions and processing capacity constraints as we continue to explore and develop our Wolfcamp, 
Bone Spring and other liquids-rich plays in the Delaware Basin in 2021. If we were required to shut in our production 
or flare our natural gas for long periods of time due to pipeline interruptions or lack of processing facilities or 
capacity of these facilities, it could have a material adverse effect on our business, financial condition, results of
operations and cash flows.

We conduct a portion of our operations through joint ventures, which subjects us to additional risks that 
could have a material adverse effect on the success of these operations, our financial position, results of 
operations or cash flows.

We own and operate substantially all of our midstream assets in the Delaware Basin through San Mateo, and we 

may enter into other joint venture arrangements in the future. The nature of a joint venture requires us to share
a portion of control with unaffiliated third parties. If our joint venture partners do not fulfill their contractual and other 
obligations, the affected joint venture may be unable to operate according to its business plan, and we may be 
required to increase our level of financial commitment or seek third-party capital, which could dilute our ownership 
in the applicable joint venture. If we do not timely meet our financial commitments or otherwise comply with our 
joint venture agreements, our ownership of and rights with respect to the applicable joint venture may be reduced 
or otherwise adversely affected. Furthermore, there can be no assurance that any joint venture will be successful or 
generate cash flows at the level we have anticipated, or at all. Differences in views among joint venture participants
could also result in delays in business decisions or otherwise, failures to agree on major issues, operational 
inefficiencies and impasses, litigation or other issues. We provide management functions for San Mateo and may 
provide such services for future joint venture arrangements, which may require additional time and attention of
management or require us to hire or contract additional personnel. Third parties may also seek to hold us liable for a
joint venture’s liabilities. These issues or any other difficulties that cause a joint venture to deviate from its original 
business plan could have a material adverse effect on our financial condition, results of operations and cash flows.

Because of the natural decline in production in the regions of San Mateo’s midstream operations,  
San Mateo’s long-term success depends on its ability to obtain new sources of products, which depends  
on certain factors beyond San Mateo’s control. Any decrease in supplies to its midstream facilities could 
adversely affect San Mateo’s business and operating results.

San Mateo’s midstream facilities are, or will be, connected to oil and natural gas wells operated by us or by third

parties from which production will naturally decline over time, which means that the cash flows associated with 
these sources of oil, natural gas, NGLs and produced water will also decline over time. Some of these third parties 
are not subject to minimum volume commitments. To maintain or increase throughput levels on San Mateo’s 
gathering systems and the utilization rate at its other midstream facilities, San Mateo must continually obtain new 
sources of products. San Mateo’s ability to obtain additional sources of oil, natural gas, NGLs and produced 
water depends, in part, on the level of successful drilling and production activity near its gathering and transportation 
systems and other midstream facilities. San Mateo has no control over the level of activity in the areas of its
operations, the amount of reserves associated with the wells or the rate at which production from a well will decline. 
In addition, San Mateo has no control over producers or their drilling or production decisions, which are affected by,
among other things, prevailing and projected energy prices, demand for hydrocarbons, the level of reserves, 
geological considerations, governmental regulations, the availability of drilling rigs, other production and development
costs and the availability and cost of capital.

We have entered into certain long-term contracts that require us to pay fees to our service providers based 
on minimum volumes regardless of actual volume throughput and that may limit our ability to use other 
service providers.

From time to time, we have entered into and may in the future enter into certain oil, natural gas or produced
water gathering or transportation agreements, natural gas processing agreements, NGL transportation agreements, 
produced water disposal agreements or similar commercial arrangements with midstream companies, including 
San Mateo. Certain of these agreements require us to meet minimum volume commitments, often regardless of
actual throughput. Our reduced drilling activity could result in insufficient production to fulfill our obligations under 
these agreements. As of December 31, 2020, our long-term contractual obligations under agreements with 
minimum volume commitments totaled approximately $1.1 billion over the terms of the agreements. If we have 
insufficient production to meet the minimum volume commitments under any of these agreements, our cash flow 
from operations will be reduced, which may require us to reduce or delay our planned investments and capital 
expenditures or seek alternative means of financing, all of which may have a material adverse effect on our results 
of operations.

Pursuant to certain of our agreements with midstream companies, we have dedicated our current and future
leasehold interests in certain of our asset areas to counterparties. As a result, we will be limited in our ability to 
use other gathering, processing, disposal and transportation service providers, even if such service providers are
able to offer us more favorable pricing or more efficient service.

We do not own all of the land on which our midstream assets are located, which could disrupt our operations.

We do not own all of the land on which our midstream assets are located, and we are therefore subject to the

possibility of more onerous terms and/or increased costs or royalties to retain necessary land access if we do 
not have valid rights-of-way or leases or if such rights-of-way or leases lapse or terminate. We sometimes obtain the 
rights to land owned by third parties and governmental agencies for a specific period of time. Our loss of these 
rights, through our inability to renew right-of-way contracts, leases or otherwise, could cause us to cease operations 
on the affected land or find alternative locations for our operations at increased costs, each of which could have a 
material adverse effect on our business, financial condition, results of operations and cash flows.

Competition in the oil and natural gas industry is intense, making it more difficult for us to acquire 
properties, market oil and natural gas, provide midstream services and secure trained personnel, and our 
competitors may use superior technology and data resources that we may be unable to afford.

Competition is intense in virtually all facets of our business. Our ability to acquire additional prospects and to find 

and develop reserves in the future will depend in part on our ability to evaluate and select suitable properties and 
to consummate transactions in a highly competitive environment for acquiring properties, marketing oil and natural 
gas and securing trained personnel. Similarly, our midstream business, and particularly the success of San Mateo, 
depends in part on our ability to compete with other midstream service companies to attract third-party customers
to our midstream facilities. San Mateo competes with other midstream companies that provide similar services
in its areas of operations, and such companies may have legacy relationships with producers in those areas and may 
have a longer history of efficiency and reliability. Also, there is substantial competition for capital available for 
investment in the oil and natural gas industry. Many of our competitors possess and employ financial, technical, 
technological and personnel resources substantially greater than ours. Those companies may be able to pay more
for productive oil and natural gas properties and exploratory prospects and to evaluate, bid for and purchase 
a greater number of properties and prospects than our financial, technical, technological or personnel resources 
permit. As our competitors use or develop new technologies, we may be placed at a competitive disadvantage,
and competitive pressures may force us to implement new technologies at a substantial cost. We cannot be certain 
that we will be able to implement technologies on a timely basis or at a cost that is acceptable to us. One or more
of the technologies that we use or that we may implement in the future may become obsolete, and our operations 
may be adversely affected.

In addition, other companies may be able to offer better compensation packages to attract and retain qualified

personnel than we are able to offer. The cost to attract and retain qualified personnel has increased in recent
years due to competition and may increase substantially in the future. We may not be able to compete successfully 
in the future in acquiring prospective reserves, developing reserves, developing midstream assets, marketing 
hydrocarbons, attracting and retaining quality personnel and raising additional capital, which could have a material
adverse effect on our business, financial condition, results of operations and cash flows.

Strategic relationships upon which we may rely are subject to change, which may diminish our ability to 
conduct our operations.

Our ability to explore, develop and produce oil and natural gas resources successfully, acquire oil and natural
gas interests and acreage and conduct our midstream activities depends on our developing and maintaining close
working relationships with industry participants and on our ability to select and evaluate suitable acquisition
opportunities in a highly competitive environment. These relationships are subject to change and, if they do, our
ability to grow may be impaired.

To develop our business, we endeavor to use the business relationships of our management, Board of Directors 
and special Board advisors to enter into strategic relationships, which may take the form of contractual arrangements
with other oil and natural gas companies and service companies, including those that supply equipment and other
resources that we expect to use in our business, as well as midstream companies and certain financial institutions.
We may not be able to establish these strategic relationships, or if established, we may not be able to maintain
them. In addition, the dynamics of our relationships with strategic partners may require us to incur expenses or 
undertake activities we would not otherwise be inclined to incur or undertake in order to fulfill our obligations
to these partners or maintain our relationships. If our strategic relationships are not established or maintained, our
business prospects may be limited, which could diminish our ability to conduct our operations.

We have limited control over activities on properties we do not operate.

We are not the operator on some of our properties, particularly in the Haynesville shale. We also have other

non-operated acreage positions in Northwest Louisiana, Southeast New Mexico, West Texas and South Texas.
Because we are not the operator for these properties, our ability to exercise influence over the operations of these
properties or their associated costs is limited. Our dependence on the operators and other working interest
owners of these projects and our limited ability to influence operations and associated costs, or control the risks, 
could materially and adversely affect the drilling results, reserves and future cash flows from these properties.
The success and timing of our drilling and development activities on properties operated by others therefore 
depends upon a number of factors, including:

•

•

•

the timing and amount of capital expenditures;

the operator’s expertise and financial resources;

the rate of production of reserves, if any;

• approval of other participants in drilling wells; and

• selection and implementation or execution of technology.

In areas where we do not have the right to propose the drilling of wells, we may have limited influence on when,

how and at what pace our properties in those areas are developed. Further, the operators of those properties 
may experience financial problems in the future or may sell their rights to another operator not of our choosing, both 
of which could limit our ability to develop and monetize the underlying oil or natural gas reserves. In addition, the 
operators of these properties may elect to curtail the oil or natural gas production or to shut in the wells on these 
properties during periods of low oil or natural gas prices, and we may receive less than anticipated or no production 
and associated revenues from these properties until the operator elects to return them to production.

RISKS RELATED TO LAWS AND REGULATIONS

Approximately 28% of our leasehold and mineral acres in the Delaware Basin is located on federal lands, 
which are subject to administrative permitting requirements and potential federal legislation, regulation and 
orders that may limit or restrict oil and natural gas operations on federal lands.

At December 31, 2020, Matador held approximately 124,700 net leasehold and mineral acres in the Delaware
Basin in Eddy and Lea Counties, New Mexico and in Loving County, Texas, of which approximately 34,500 net acres, 
or about 28%, were on federal lands administered by the BLM. In addition to permits issued by state and local 
authorities, oil and natural gas activities on federal lands also require permits from the BLM. Permitting for oil and 
natural gas activities on federal lands can take significantly longer than the permitting process for oil and natural gas
activities not located on federal lands. Delays in obtaining necessary permits can disrupt our operations and have
an adverse effect on our business. These BLM leases contain relatively standardized terms and require compliance 
with detailed regulations and orders, which are subject to change. These operations are also subject to BLM rules 
regarding engineering and construction specifications for production facilities, safety procedures, the valuation of
production, the payment of royalties, the removal of facilities, the posting of bonds, hydraulic fracturing, the control 
of air emissions and other areas of environmental protection. These rules could result in increased compliance 
costs for our operations, which in turn could have an adverse effect on our business and results of operations.
Under certain circumstances, the BLM may require our operations on federal leases to be suspended or terminated.

MATADOR RESOURCES COMPANY 

In addition, litigation related to leasing and permitting of federal lands could also restrict, delay or limit our ability to 
conduct operations on our federal leasehold or acquire additional federal leasehold. In January 2021, the Biden
administration issued the Biden Administration Federal Lease Orders. The impact of these federal actions remains
unclear, and if the restrictions do not lapse, or other limitations or prohibitions become effective, our oil and natural 
gas operations on federal lands could be adversely impacted. At the federal level, various policy makers, regulatory 
agencies and political candidates, including President Biden, have also proposed restrictions on hydraulic fracturing, 
including its outright prohibition. It is possible that any such restrictions on hydraulic fracturing may particularly
target activity on federal lands. Any federal legislation, regulations or orders intended to limit or restrict oil and 
natural gas operations on federal lands, if enacted, could have an adverse impact on our business, financial condition, 
results of operations and cash flows.

Oil and natural gas exploration and production activities on federal lands are also subject to NEPA, which requires

federal agencies, including the Department of Interior, to evaluate major agency actions having the potential to 
significantly impact the environment. In the course of such evaluations, an agency will prepare an environmental 
assessment that assesses impacts that are “reasonably foreseeable” and have a “reasonably close causal
relationship” to the agency action under review and, if necessary, will prepare a more detailed environmental impact
statement that may be made available for public review and comment. This process, including any additional
requirements that may be implemented, has the potential to delay or even halt development of future oil and 
natural gas projects with NEPA applicability.

We are subject to government regulation and liability, including complex environmental laws, which could 
require significant expenditures.

The exploration, development, production, gathering, processing, transportation and sale of oil and natural

gas in the United States are subject to many federal, state and local laws, rules and regulations, including complex 
environmental laws and regulations. The change in the presidential administration may also increase the
uncertainty with regard to potential changes in these laws, rules and regulations and the enforcement of any new 
legislation or directives by governmental authorities. Matters subject to regulation include discharge permits,
drilling bonds, reports concerning operations, the spacing of wells, unitization and pooling of properties, taxation,
gathering and transportation of oil, natural gas and NGLs, gathering and disposal of produced water, environmental
matters and health and safety criteria addressing worker protection. Under these laws and regulations, we 
may be required to make large expenditures that could materially adversely affect our financial condition, results
of operations and cash flows. If existing laws and regulations are revised or reinterpreted, or if new laws and
regulations become applicable to our operations or those of our service providers, such changes may affect the
costs that we pay for such services or the results of business. In addition to expenditures required in order 
for us to comply with such laws and regulations, expenditures required by such laws and regulations could also 
include payments and fines for:

• personal injuries;

• property damage;

• containment and clean-up of oil, produced water and other spills;

• management and disposal of hazardous materials;

•

remediation, clean-up costs and natural resource damages; and

• other environmental damages.

FORM 10-K PART I

2020 ANNUAL REPORT

We do not believe that full insurance coverage for all potential damages is available at a reasonable cost. Failure 

to comply with these laws and regulations may also result in the suspension or termination of our operations 
and subject us to administrative, civil and criminal penalties, injunctive relief and/or the imposition of investigatory or
other remedial obligations. The costs of remedying noncompliance may be significant, and remediation obligations 
could adversely affect our financial condition, results of operations and leasehold acreage. Laws, rules and 
regulations protecting the environment have changed frequently and the changes often include increasingly stringent 
requirements. These laws, rules and regulations may impose liability on us for environmental damage and disposal
of hazardous and non-hazardous materials even if we were not negligent or at fault. We may also be found to be
liable for the conduct of others or for acts that complied with applicable laws, rules or regulations at the time 
we performed those acts. These laws, rules and regulations are interpreted and enforced by numerous federal and 
state agencies. In addition, private parties, including the owners of properties upon which our wells are drilled
or our facilities are located, the owners of properties adjacent to or in close proximity to those properties or non-
governmental organizations such as environmental groups, may also pursue legal actions against us based on
alleged non-compliance with certain of these laws, rules and regulations. For example, a number of lawsuits have 
been filed in some states alleging that fluid injection or oil and natural gas extraction have caused damage to
neighboring properties or otherwise violated state and federal rules regulating waste disposal. Private parties may
also pursue legal actions challenging permitting programs that authorize certain of our operations. For example, 
it is possible that courts could vacate relevant NWPs as such potential permit coverage relates to activities in the oil 
and natural gas sector, or the Biden administration could choose to suspend the availability of NWPs in the future, 
thereby forcing our relevant operations to seek coverage under individual permits under CWA Section 404 (which is
a longer and more administratively complex process that is subject to NEPA).

Part of the regulatory environment in which we operate includes, in some cases, federal requirements for 
obtaining environmental assessments, environmental impact statements and/or plans of development before
commencing exploration and production or midstream activities. Oil and natural gas operations in certain of
our operating areas can be adversely affected by seasonal or permanent restrictions on drilling activities designed 
to protect various wildlife. Furthermore, we participate in candidate conservation agreements for the lesser
prairie-chicken, the sand dune lizard and the Texas hornshell mussel, pursuant to which we are restricted from 
operating in certain sensitive locations or at certain times. Participation in such agreements or the designation 
of previously unprotected species as threatened or endangered species could prohibit drilling or other operations in 
certain of our operating areas, cause us to incur increased costs arising from species protection measures or 
result in limitations on our exploration and production and midstream activities, each of which could have an adverse
impact on our business, financial condition, results of operations and cash flows. See “Business—Regulation.”

We are subject to federal, state and local taxes and may become subject to new taxes or have eliminated  
or reduced certain federal income tax deductions currently available with respect to oil and natural  
gas exploration and production activities as a result of future legislation, which could adversely affect our 
business, financial condition, results of operations and cash flows.

The federal, state and local governments in the areas in which we operate impose taxes on the oil and natural 

gas products we sell and, for many of our wells, sales and use taxes on significant portions of our drilling and
operating costs. Many states have raised state taxes on energy sources or state taxes associated with the 
extraction of hydrocarbons, and additional increases may occur. In addition, there has been a significant amount of 
discussion by legislators and presidential administrations concerning a variety of energy tax proposals.

Periodically, legislation is introduced to eliminate certain key U.S. federal income tax preferences currently

available to oil and natural gas exploration and production companies. Such changes include, but are not limited to, 
(i) the repeal of the percentage depletion allowance for certain oil and natural gas properties, (ii) the elimination 
of current deductions for intangible drilling and development costs, (iii) the elimination of the deduction for certain

      FORM 10-K PART I

MATADOR RESOURCES COMPANY 

U.S. production or manufacturing activities and (iv) the increase in the amortization period for geological and
geophysical costs paid or incurred in connection with the exploration for, or development of, oil or natural gas within
the United States. The Tax Cuts and Jobs Act did not include any of these proposals, except for the repeal of the 
domestic manufacturing tax deduction for oil and natural gas companies. It is possible, however, that such provisions 
could be proposed in the future. The passage of any legislation or any other similar change in U.S. federal income 
tax law could affect certain tax deductions that are currently available with respect to oil and natural gas exploration
and production activities and could negatively impact our financial condition, results of operations and cash flows.

In 2019, a bill was introduced in the New Mexico Senate to add a surtax on natural gas processors that would

have started at $0.60 per MMBtu in 2020 and escalated to $3.00 per MMBtu by 2024. Although the bill did not 
pass, any such surtax would adversely affect the ability of San Mateo and other natural gas processors to operate
in New Mexico and would adversely affect the prices we receive for our natural gas processed in New Mexico.

The Tax Cuts and Jobs Act may impact our ability to fully utilize our interest expense deductions and net 
operating loss carryforwards to fully offset our taxable income in future periods.

The Tax Cuts and Jobs Act includes provisions that generally (i) limit our annual deductions for interest expense
to no more than 30% of our “adjusted taxable income” (plus 100% of our business interest income) for the year, 
(ii) permit us to offset only 80% (rather than 100%) of our taxable income with net operating losses we generate and 
(iii) limit our ability to deduct certain elements of executive compensation. Interest expense and net operating 
losses subject to these limitations may be carried forward by us for use in later years, subject to these limitations.
Additionally, the Tax Cuts and Jobs Act repealed the domestic manufacturing tax deduction for oil and natural gas 
companies. These tax law changes could have the effect of causing us to incur income tax liability sooner than 
we otherwise would have incurred such liability or, in certain cases, could cause us to incur income tax liability that we 
might not have incurred otherwise, in the absence of these tax law changes.

Federal and state legislation and regulatory initiatives relating to hydraulic fracturing could result in 
increased costs and additional operating restrictions or delays.

Hydraulic fracturing involves the injection of water, sand or other proppants and chemicals under pressure into 
rock formations to stimulate oil and natural gas production. We routinely use hydraulic fracturing to complete wells 
in order to produce oil, natural gas and NGLs from formations such as the Wolfcamp and Bone Spring plays, the 
Eagle Ford shale and the Haynesville shale, where we focus our operations. Hydraulic fracturing has been regulated
at the state and local level through permitting and compliance requirements. Federal, state and local laws or 
regulations targeting various aspects of the hydraulic fracturing process are being considered, or have been proposed 
or implemented. In past sessions, Congress has considered, but has not passed, legislation to amend the SDWA, 
to remove the SDWA’s exemption granted to most hydraulic fracturing operations (other than operations using fluids 
containing diesel) and to require reporting and disclosure of chemicals used by oil and natural gas companies 
in the hydraulic fracturing process. Also at the federal level, in March 2015, the BLM issued final rules, including
new requirements relating to public disclosure, wellbore integrity and handling of flowback water, to regulate 
hydraulic fracturing on federal and Indian lands. These rules were rescinded by rule in December 2017; however, in 
January 2018, California and a coalition of environmental groups filed a lawsuit in the Northern District of 
California to challenge the BLM’s rescission of the rules. The Northern District of California upheld the rescission 
in 2020, but this decision was then appealed to the Ninth Circuit Court of Appeals. This litigation is ongoing and 
future implementation of the BLM rules is uncertain at this time.

Various policymakers, regulatory agencies and political candidates at the federal, state and local levels have 

proposed restrictions on hydraulic fracturing, including its outright prohibition. At various times during his campaign, 
President Biden indicated support for prohibitions of hydraulic fracturing on federal lands or outright. Any such 
restrictions on hydraulic fracturing on federal lands could adversely impact our operations in the Delaware Basin,

FORM 10-K PART I

2020 ANNUAL REPORT

75    

and an outright prohibition would adversely impact all of our operations. In addition, a number of states and local
regulatory authorities are considering or have implemented more stringent regulatory requirements applicable to
hydraulic fracturing, including bans or moratoria on drilling that effectively prohibit further production of oil and 
natural gas through the use of hydraulic fracturing or similar operations. For example, in December 2014, New York
announced a moratorium on high volume fracturing activities combined with horizontal drilling following the
issuance of a study regarding the safety of hydraulic fracturing. Certain communities in Colorado have also enacted
bans on hydraulic fracturing. These actions are the subject of legal challenges. Texas and New Mexico have
adopted regulations that require the disclosure of information regarding the substances used in the hydraulic
fracturing process. Recently, bills have been introduced in the New Mexico legislature to place a moratorium on,
ban or otherwise restrict hydraulic fracturing activities, including prohibiting the injection of fresh water in 
such operations. Although such bills have not passed, similar laws, rules, regulations or orders at the local, state 
or federal level could limit our operations.

The adoption of new laws or regulations imposing reporting or operational obligations on, or otherwise limiting or 

prohibiting, the hydraulic fracturing process could make it more difficult to complete oil and natural gas wells in
unconventional plays. In addition, if hydraulic fracturing becomes regulated at the federal level as a result of federal 
legislation or regulatory initiatives by the EPA or BLM, hydraulic fracturing activities could become subject to 
additional permitting requirements, and also to attendant permitting delays and potential increases in cost, which
could adversely affect our business and results of operations.

The potential adoption of federal, state and local legislation and regulations intended to address potential 
induced seismicity in the areas in which we operate could restrict our drilling and production activities,  
as well as our ability to dispose of produced water gathered from such activities, which could decrease 
San Mateo’s revenues and result in increased costs and additional operating restrictions or delays.

State and federal regulatory agencies recently have focused on a possible connection between the operation of 

injection wells used for produced water disposal and the increased occurrence of seismic activity. When caused
by human activity, such events are called “induced seismicity.” Regulatory agencies at all levels are continuing to
study the possible link between oil and natural gas activity and induced seismicity. In addition, a number of lawsuits 
have been filed in some states alleging that fluid injection or oil and natural gas extraction have caused damage to 
neighboring properties or otherwise violated state and federal rules regulating waste disposal. In response to these 
concerns, regulators in some states are seeking to impose additional requirements, including requirements
regarding the permitting of salt water disposal wells or otherwise, to assess the relationship between seismicity
and the use of such wells.

While the scientific community and regulatory agencies at all levels are continuing to study the possible link 
between oil and natural gas activity and induced seismicity, some state regulatory agencies, including in Texas and 
New Mexico, have modified their regulations or guidance to mitigate potential causes of induced seismicity.

Increased seismicity in areas in which we operate could result in additional regulation and restrictions on our 
operations and could lead to operational delays or increased operating costs. Additional regulation and attention 
given to induced seismicity could also lead to greater opposition, including litigation, to oil and natural gas activities. 
We and San Mateo dispose of large volumes of produced water gathered from our and third parties’ drilling and 
production operations by injecting it into wells pursuant to permits issued to us by governmental authorities
overseeing such disposal activities. While these permits are issued pursuant to existing laws and regulations, these 
legal requirements are subject to change, which could result in the imposition of more stringent operating constraints
or new monitoring and reporting requirements, owing to, among other things, concerns of the public or governmental
authorities regarding such gathering or disposal activities. The adoption and implementation of any new laws or
regulations that restrict our ability to dispose of produced water gathered from drilling and production activities could 
decrease San Mateo’s revenues and result in increased costs and additional operating restrictions or delays.

Legislation or regulations restricting emissions of greenhouse gases could result in increased operating 
costs and reduced demand for the oil, natural gas and NGLs we produce, while the physical effects  
of climate change could disrupt our production and cause us to incur significant costs in preparing for  
or responding to those effects.

We believe it is likely that scientific and political attention to issues concerning the extent, causes of and 
responsibility for climate change will continue, with the potential for further regulations and litigation that could
affect our operations. Our operations result in greenhouse gas emissions. The EPA has published its final findings
that emissions of carbon dioxide, methane and other greenhouse gases present an endangerment to public 
health and welfare because emissions of such gases are, according to the EPA, contributing to the warming of the
earth’s atmosphere and other climatic changes. There were attempts at comprehensive federal legislation 
establishing a cap and trade program, but that legislation did not pass. Further, various states have considered or 
adopted legislation that seeks to control or reduce emissions of greenhouse gases from a wide range of sources. 
Internationally, in 2015, the United States participated in the United Nations Conference on Climate Change,
which led to the creation of the Paris Agreement. The Paris Agreement, which was signed by the United States in 
April 2016, requires countries to review and “represent a progression” in their intended nationally determined
contributions, which set greenhouse gas emission reduction goals, every five years beginning in 2020. While the 
United States exited the Paris Agreement in November 2020, effective February 19, 2021, President Biden 
caused the United States to rejoin the Paris Agreement. In 2019, New Mexico’s governor signed an executive order 
declaring that New Mexico would support the goals of the Paris Agreement by joining the U.S. Climate Alliance, 
a bipartisan coalition of governors committed to reducing greenhouse gas emissions consistent with the goals of 
the Paris Agreement. The stated objective of the executive order is to achieve a statewide reduction in greenhouse 
gas emissions of at least 45% by 2030 as compared to 2005 levels. The executive order also requires New Mexico
regulatory agencies to create an “enforceable regulatory framework” to ensure methane emission reductions.
Following that executive order, the NMOCD, NMED and New Mexico legislature have proposed various rules, 
regulations and bills regarding the reduction of natural gas waste and the control of emissions that would, among
other items, require upstream and midstream operators to reduce natural gas waste by a fixed amount each year 
and achieve a 98% natural gas capture rate by the end of 2026. The EPA has also finalized regulations targeting
new sources of methane emissions from the oil and natural gas industry. While in August 2020, the EPA rescinded 
or modified certain methane and volatile organic compound emissions standards for oil and natural gas operations,
President Biden has requested the EPA to consider establishing new emissions standards. Any future international 
agreements, federal or state laws or implementing regulations that may be adopted to address greenhouse gas 
emissions could, and in all likelihood would, require us to incur increased operating costs, adversely affecting our 
profits, and could adversely affect demand for the oil and natural gas we produce, depressing the prices we receive
for oil and natural gas.

In an interpretative guidance on climate change disclosures, the SEC indicated that climate change could have
an effect on the severity of weather (including hurricanes and floods), sea levels, the arability of farmland and water
availability and quality. If such effects were to occur, there is the potential for our exploration and production 
operations to be adversely affected. Potential adverse effects could include damages to our facilities from powerful
winds or rising waters in low-lying areas, disruption of our production, less efficient or non-routine operating
practices necessitated by climate effects and increased costs for insurance coverage in the aftermath of such effects. 
Significant physical effects of climate change could also have an indirect effect on our financing and operations 
by disrupting the transportation or process-related services provided by us or other midstream companies, service
companies or suppliers with whom we have a business relationship. We may not be able to recover through
insurance some or any of the damages, losses or costs that may result from potential physical effects of climate

change. In addition, our hydraulic fracturing operations require large amounts of water. See “—Risks Related
to our Operations—If we are unable to acquire adequate supplies of water for our drilling and hydraulic fracturing 
operations or are unable to dispose of the water we use at a reasonable cost and pursuant to applicable 
environmental rules, our ability to produce oil and natural gas commercially and in commercial quantities could be
impaired.” Should climate change or other drought conditions occur, our ability to obtain water of a sufficient
quality and quantity could be impacted and in turn, our ability to perform hydraulic fracturing operations could be 
restricted or made more costly.

The adoption of legislation or regulatory programs to reduce greenhouse gas emissions could require us to incur

increased operating costs, such as costs to purchase and operate emissions control systems, to acquire emissions
allowances or to comply with new regulatory or reporting requirements. Any such legislation or regulatory programs 
could also increase the cost of consuming, and thereby reduce demand for, the oil and natural gas we produce.
Consequently, legislation and regulatory programs to reduce emissions of greenhouse gases could have an adverse
effect on our business, financial condition and results of operations. Reduced demand for the oil and natural gas 
that we produce could also have the effect of lowering the value of our reserves. In addition, there have also been
efforts in recent years to influence the investment community, including investment advisors and certain sovereign
wealth, pension and endowment funds, promoting divestment of fossil fuel equities and pressuring lenders to limit 
funding to companies engaged in the extraction of fossil fuel reserves. Such environmental activism and initiatives 
aimed at limiting climate change and reducing air pollution could interfere with our business activities, operations
and ability to access capital. Additionally, the threat of climate change has resulted in increasing political risk in the 
United States as various policy makers, regulatory agencies and political candidates at the federal, state and local 
levels have proposed bans of new leases for production of minerals on federal properties and various restrictions on
hydraulic fracturing, including its outright prohibition. In January 2021, the Biden administration issued the Biden
Administration Federal Lease Orders. The impact of these federal actions remains unclear, and if the restrictions do 
not lapse, or other limitations or prohibitions become effective, our oil and natural gas operations on federal lands 
could be adversely impacted.

President Biden and the Democratic Party, which now controls Congress, have identified climate change as a 
priority, and it is expected that new executive orders, regulatory action and/or legislation targeting greenhouse gas
emissions, or prohibiting or restricting oil and natural gas development activities in certain areas, will be proposed
and/or promulgated during the Biden administration. In addition, the Biden administration has already issued multiple
executive orders pertaining to environmental regulations and climate change, including the Executive Order on 
Protecting Public Health and the Environment and Restoring Science to Tackle the Climate Crisis and the Executive
Order on Tackling the Climate Crisis at Home and Abroad. In the latter executive order, President Biden
established climate change as a primary foreign policy and national security consideration, affirmed that achieving
net-zero greenhouse gas emissions by or before 2050 is a critical priority, affirmed his administration’s desire
to establish the United States as a leader in addressing climate change and generally further integrated climate 
change and environmental justice considerations into government agencies’ decision-making, among other
measures. Finally, increasing attention to the risks of climate change has resulted in an increased possibility of
lawsuits or investigations brought by public and private entities against oil and natural gas companies in 
connection with their greenhouse gas emissions. Should we be targeted by any such litigation or investigations,
we may incur liability, which, to the extent that societal pressures or political or other factors are involved, could 
be imposed without regard to the causation of or contribution to the asserted damage, or to other mitigating
factors. The ultimate impact of greenhouse gas emissions-related agreements, legislation and measures on our
financial performance is highly uncertain because we are unable to predict, for a multitude of individual 
jurisdictions, the outcome of political decision-making processes and the variables and trade-offs that inevitably 
occur in connection with such processes.

New regulations on all emissions from our operations could cause us to incur significant costs.

In recent years, the EPA issued final rules to subject oil and natural gas operations to regulation under the
New Source Performance Standards (“NSPS”) and National Emission Standards for Hazardous Air Pollutants 
programs under the CAA and to impose new and amended requirements under both programs. The EPA rules
include NSPS standards for completions of hydraulically fractured oil and natural gas wells, compressors, controllers, 
dehydrators, storage tanks, natural gas processing plants and certain other equipment. These rules have required
changes to our operations, including the installation of new equipment to control emissions. The EPA finalized 
a more stringent National Ambient Air Quality Standard (“NAAQS”) for ozone in October 2015. The EPA finished
promulgating final area designations under the new standard in 2018, which, to the extent areas in which we
operate have been classified as “non-attainment” areas, may result in an increase in costs for emission controls and 
requirements for additional monitoring and testing, as well as a more cumbersome permitting process. To the
extent regions reclassified as non-attainment areas under the lower ozone standard have begun implementing new, 
more stringent regulations, those regulations could also apply to our or San Mateo’s customers’ operations.
Generally, it takes states several years to develop compliance plans for their non-attainment areas. In November 2016,
the Department of the Interior issued final rules relating to the venting, flaring and leaking of natural gas by oil and
natural gas producers who operate on federal and Indian lands. The rules limit routine flaring of natural gas, require
the payment of royalties on avoidable natural gas losses and require plans or programs relating to natural gas 
capture and leak detection and repair. The BLM then finalized a revised rule in 2018 that scaled back the waste-
prevention requirements of the 2016 rule, but this revised rule was vacated by a California federal district court in 
2020, a decision which the BLM has appealed to the Ninth Circuit Court of Appeals. If not withdrawn or significantly
revised, these rules are expected to result in an increase to our operating costs and changes in our operations. In
addition, several states are pursuing similar measures to regulate emissions of methane from new and existing 
sources within the oil and natural gas source category. As a result of this continued regulatory focus, future federal
and state regulations of the oil and natural gas industry remain a possibility and could result in increased compliance
costs for our operations.

We may incur significant costs and liabilities resulting from compliance with pipeline safety regulations.

Our pipelines are subject to stringent and complex regulation related to pipeline safety and integrity

management. For instance, the Department of Transportation, through PHMSA, has established a series of rules 
that require pipeline operators to develop and implement integrity management programs for hazardous liquid
(including oil) pipeline segments that, in the event of a leak or rupture, could affect high-consequence areas. The
Rustler Breaks Oil Pipeline System is subject to such rules. PHMSA also recently proposed rulemaking that
would expand existing integrity management requirements to natural gas transmission and gathering lines in areas
with medium population densities. Additional action by PHMSA with respect to pipeline integrity management
requirements may occur in the future. At this time, we cannot predict the cost of such requirements, but they could
be significant. Moreover, violations of pipeline safety regulations can result in the imposition of significant penalties.

Several states have also passed legislation or promulgated rules to address pipeline safety. Compliance with 

pipeline integrity laws and other pipeline safety regulations issued by state agencies such as the RRC and the
NMOCD could result in substantial expenditures for testing, repairs and replacement. Due to the possibility of new 
or amended laws and regulations or reinterpretation of existing laws and regulations, there can be no assurance
that future compliance with PHMSA or state requirements will not have a material adverse effect on our results of
operations or financial position.

A change in the jurisdictional characterization of some of our assets by FERC or a change in policy 
by FERC may result in increased regulation of our assets, which may cause our revenues to decline and 
operating expenses to increase.

Section 1(b) of the NGA exempts natural gas gathering facilities from regulation by FERC under the NGA. We 
believe that the natural gas pipelines in our gathering systems meet the traditional tests FERC has used to establish
a pipeline’s status as a gatherer not subject to FERC regulation. However, the distinction between FERC-regulated 
transmission services and federally unregulated gathering services is the subject of ongoing litigation, so the
classification and regulation of our gathering facilities are subject to change based on future determinations by
FERC, the courts or Congress. Similarly, intrastate crude oil pipeline facilities are exempt from regulation by 
FERC under the ICA. San Mateo’s Rustler Breaks Oil Pipeline System, which includes crude oil gathering and 
transportation pipelines from origin points in Eddy County, New Mexico to an interconnect with Plains, is subject
to FERC jurisdiction. We believe the other crude oil pipelines in our gathering systems meet the traditional tests 
FERC has used to establish a pipeline’s status as an intrastate facility not subject to FERC regulation. Whether
a pipeline provides service in interstate commerce or intrastate commerce is highly fact dependent and determined 
on a case-by-case basis. A change in the jurisdictional characterization of our facilities by FERC, the courts or Congress, 
a change in policy by FERC or Congress or the expansion of our activities may result in increased regulation of our
assets, which may cause our revenues to decline and operating expenses to increase.

The rates of our regulated assets are subject to review and reporting by federal regulators, which could 
adversely affect our revenues.

The Rustler Breaks Oil Pipeline System transports crude oil in interstate commerce. FERC regulates the rates,

terms and conditions of service on pipelines that transport crude oil in interstate commerce. If a party with an 
economic interest were to file either a complaint against our tariff rates or protest any proposed increases to our
tariff rates, or FERC were to initiate an investigation of our rates, then our rates could be subject to detailed
review. If any proposed rate increases were found by FERC to be in excess of just and reasonable levels, FERC
could order us to reduce our rates and to refund the amount by which the rate increases were determined to be 
excessive, plus interest. If our existing rates were found by FERC to be in excess of just and reasonable levels, we 
could be ordered to refund the excess we collected for up to two years prior to the date of the filing of the 
complaint challenging the rates, and we could be ordered to reduce our rates prospectively. In addition, a state 
commission also could investigate our intrastate rates or our terms and conditions of service on its own initiative
or at the urging of a shipper or other interested party. If a state commission found that our rates exceeded levels 
justified by our cost of service, the state commission could order us to reduce our rates. Any such reductions may
result in lower revenues and cash flows.

In addition, FERC’s ratemaking policies are subject to change and may impact the rates charged and revenues
received on the Rustler Breaks Oil Pipeline System and any other natural gas or crude oil pipeline that is determined
to be under the jurisdiction of FERC.

Should we fail to comply with all applicable FERC-administered statutes, rules, regulations and orders, we 
could be subject to substantial penalties and fines.

Under the Energy Policy Act, FERC has civil penalty authority under the NGA to impose penalties for current 

violations of up to approximately $1.2 million per day for each violation and disgorgement of profits associated
with any violation. This maximum penalty authority established by statute will continue to be adjusted periodically 
for inflation. While the nature of our gathering facilities is such that these facilities have not yet been regulated by 
FERC, the Rustler Breaks Oil Pipeline System does transport crude oil in interstate commerce and, therefore, is
subject to FERC regulation. Laws, rules and regulations pertaining to those and other matters may be considered or
adopted by FERC or Congress from time to time. Failure to comply with those laws, rules and regulations in the 
future could subject us to civil penalty liability.

The derivatives legislation adopted by Congress could have an adverse impact on our ability to hedge risks 
associated with our business.

The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), among other things, 

established federal oversight and regulation of certain derivative products, including commodity hedges of the
type we use. The Dodd-Frank Act requires the Commodity Futures Trading Commission (“CFTC”) and the SEC to
promulgate rules and regulations implementing the Dodd-Frank Act. Although the CFTC has finalized certain 
regulations, others remain to be finalized or implemented, and it is not possible at this time to predict when, or if, 
this will be accomplished.

In 2011, the CFTC issued regulations to set position limits for certain futures and option contracts in the major 
energy markets and for swaps that are their economic equivalents. The initial position limits rule was vacated by the 
United States District Court for the District of Columbia in 2012. However, in 2013, the CFTC proposed new rules
that would place limits on positions in certain core futures and equivalent swaps contracts for or linked to certain
physical commodities, subject to exceptions for certain bona fide hedging transactions. In 2016, the CFTC decided 
to re-propose, rather than finalize, certain regulations, including limitations on speculative futures and swap 
positions. The CFTC has not acted on the re-proposed position limit regulations. As these new position limit rules 
are not yet final, the impact of those provisions on us is uncertain at this time. The Dodd-Frank Act could also result
in additional regulatory requirements on our derivative arrangements, which could include new margin, reporting 
and clearing requirements. In addition, this legislation could have a substantial impact on our counterparties and may
increase the cost of our derivative arrangements in the future.

If these types of commodity hedges become unavailable or uneconomic, our commodity price risk could increase,

which would increase the volatility of revenues and may decrease the amount of credit available to us. Any 
limitations or changes in our use of derivative arrangements could also materially affect our cash flows, which
could adversely affect our ability to make capital expenditures.

Finally, the Dodd-Frank Act was intended, in part, to reduce the volatility of oil and natural gas prices, which some

legislators attributed to speculative trading in derivatives and commodity instruments related to oil and natural
gas. Our revenues could therefore be adversely affected if a consequence of the Dodd-Frank Act and implementing 
regulations is to lower commodity prices.

Any of these consequences could have a material adverse effect on our business, financial condition and results 

of operations.

RISKS RELATING TO OUR COMMON STOCK

The price of our common stock has fluctuated substantially and may fluctuate substantially in the future.

Our stock price has experienced volatility and could vary significantly as a result of a number of factors. In 2020,

our stock price fluctuated between a high of $19.83 and a low of $1.11. In addition, the trading volume of our 
common stock may continue to fluctuate and cause significant price variations to occur. In the event of a drop in the
market price of our common stock, you could lose a substantial part or all of your investment in our common stock. 
In addition, the stock markets in general have experienced extreme volatility that has often been unrelated to the
operating performance of particular companies. These broad market fluctuations may adversely affect the trading
price of our common stock.

Factors that could affect our stock price or result in fluctuations in the market price or trading volume of our 

common stock include:

• our actual or anticipated operating and financial performance and drilling locations, including oil and natural

gas reserves estimates;

• quarterly variations in the rate of growth of our financial indicators, such as net income per share, net

income and cash flows, or those of companies that are perceived to be similar to us;

• changes in revenue, cash flows or earnings estimates or publication of reports by equity research analysts;

• declaration of dividends or adjustments to our dividend policy;

• speculation in the press or investment community;

• announcement or consummation of acquisitions, dispositions or joint ventures by us;

• public reaction to our operations or plans, press releases, announcements and filings with the SEC;

•

•

the publication of research or reports by industry analysts regarding the Company, its competitors or
our industry;

the enactment of federal, state or local laws, rules or regulations that restrict our ability to conduct our
operations, such as the Biden Administration Federal Lease Orders;

• sales of our common stock by the Company, directors, officers or other shareholders, or the perception that

such sales may occur;

• general financial market conditions and oil and natural gas industry market conditions, including fluctuations

in the price of oil, natural gas and NGLs;

• domestic or global health concerns, including the outbreak of contagious or pandemic diseases, such

as COVID-19;

•

•

the realization of any of the risk factors presented in this Annual Report;

the recruitment or departure of key personnel;

• commencement of, involvement in or unfavorable resolution of litigation;

•

the success of our exploration and development operations, our midstream business (including San Mateo)
and the marketing of any oil, natural gas and NGLs we produce;

• changes in market valuations of companies similar to ours; and

• domestic and international economic, legal and regulatory factors unrelated to our performance.

Conservation measures and a negative shift in market perception towards the oil and natural gas industry 
could adversely affect demand for oil and natural gas and our stock price.

Certain segments of the investor community have recently expressed negative sentiment towards investing in 
the oil and natural gas industry. Recent equity returns in the sector versus other industry sectors have led to lower
oil and natural gas representation in certain key equity market indices. Some investors, including certain pension 
funds, university endowments and family foundations, have stated policies to reduce or eliminate their investments
in the oil and natural gas sector based on social and environmental considerations. Other significant investors
have published ESG disclosure standards that companies in which they invest are expected to adopt or follow. 
Furthermore, fuel conservation measures, alternative fuel requirements, increasing consumer demand for
alternatives to oil and natural gas, technological advances in fuel economy and energy generation devices could
reduce demand for oil and natural gas. Such developments could result in downward pressure on the stock
prices of oil and natural gas companies, including ours.

Certain other stakeholders have pressured commercial and investment banks to stop funding oil and natural gas 

projects. With the continued volatility in oil and natural gas prices, and the possibility that interest rates will rise in
the near term, increasing the cost of borrowing, certain investors have emphasized capital efficiency and free cash 
flow from earnings as key drivers for energy companies, especially those primarily focused in the shale play arena. 
This may also result in a reduction of available capital funding for potential development projects, further impacting 
our future financial results. Furthermore, if we are unable to achieve the desired level of capital efficiency or free 
cash flow within the timeframe expected by the market, our stock price may be adversely affected.

Future sales of shares of our common stock by existing shareholders and future offerings of our common 
stock by us could depress the price of our common stock.

The market price of our common stock could decline as a result of sales of a large number of shares of our
common stock in the market, including shares of equity or debt securities convertible into common stock, and the
perception that these sales could occur may also depress the market price of our common stock. If our existing 
shareholders, including directors or officers, sell, or indicate an intent to sell, substantial amounts of our common
stock in the public market, the trading price of our common stock could decline significantly. Sales of our 
common stock may make it more difficult for us to sell equity securities in the future at a time and at a price that 
we deem appropriate. These sales could also cause our stock price to decrease and make it more difficult for 
you to sell shares of our common stock.

We may also sell or issue additional shares of common stock or equity or debt securities convertible into

common stock in public or private offerings or in connection with acquisitions. We cannot predict the size of future 
issuances of our common stock or convertible securities or the effect, if any, that future issuances and sales
of shares of our common stock or convertible securities would have on the market price of our common stock.

Our directors and executive officers own a significant percentage of our equity, which could give them 
influence in corporate transactions and other matters, and the interests of our directors and executive 
officers could differ from other shareholders.

As of February 23, 2021, our directors and executive officers beneficially owned approximately 7% of our

outstanding common stock. These shareholders could influence or control to some degree the outcome of matters 
requiring a shareholder vote, including the election of directors, the adoption of any amendment to our certificate 
of formation or bylaws and the approval of mergers and other significant corporate transactions. Their influence 
or control of the Company may have the effect of delaying or preventing a change of control of the Company and 
may adversely affect the voting and other rights of other shareholders. In addition, due to their ownership interest
in our common stock, our directors and executive officers may be able to remain entrenched in their positions.

Our Board can authorize the issuance of preferred stock, which could diminish the rights of holders  
of our common stock and make a change of control of the Company more difficult even if it might benefit 
our shareholders.

Our Board of Directors is authorized to issue shares of preferred stock in one or more series and to fix the voting 

powers, preferences and other rights and limitations of the preferred stock. Accordingly, we may issue shares of 
preferred stock with a preference over our common stock with respect to dividends or distributions on liquidation or 
dissolution, or that may otherwise adversely affect the voting or other rights of the holders of common stock.

Issuances of preferred stock, depending upon the rights, preferences and designations of the preferred stock,
may have the effect of delaying, deterring or preventing a change of control of the Company, even if that change of
control might benefit our shareholders.

GENERAL RISK FACTORS

We may have difficulty managing growth in our business, which could have a material adverse effect on 
our business, financial condition, results of operations and cash flows and our ability to execute our 
business plan in a timely fashion.

Because of our size, growth in accordance with our business plans, if achieved, will place a significant strain on 
our financial, technical, operational and management resources. As and when we expand our activities, including our 
midstream business, through San Mateo or otherwise, there will be additional demands on our financial, technical
and management resources. The failure to continue to upgrade our technical, administrative, operating and financial 
control systems or the occurrence of unexpected expansion difficulties, including the inability to recruit and 
retain experienced managers, geoscientists, petroleum engineers, landmen, midstream professionals, attorneys
and financial and accounting professionals, could have a material adverse effect on our business, financial condition,
results of operations and cash flows and our ability to execute our business plan in a timely fashion.

Our success depends, to a large extent, on our ability to retain our key personnel, including our chairman 
and chief executive officer, management and technical team, the members of our Board and our special 
Board advisors, and the loss of any key personnel, Board member or special Board advisor could disrupt 
our business operations.

Investors in our common stock must rely upon the ability, expertise, judgment and discretion of our 

management and the success of our technical team in identifying, evaluating and developing prospects and reserves.
Our performance and success are dependent to a large extent on the efforts and continued employment of our 
management and technical personnel, including our Chairman and Chief Executive Officer, Joseph Wm. Foran. We 
do not believe that they could be quickly replaced with personnel of equal experience and capabilities, and their 
successors may not be as effective. We have entered into employment agreements with Mr. Foran and other key 
personnel. However, these employment agreements do not ensure that these individuals will remain in our 
employment. If Mr. Foran or other key personnel resign or become unable to continue in their present roles and if
they are not adequately replaced, our business operations could be adversely affected. With the exception of 
Mr. Foran, we do not maintain, nor do we plan to obtain, any insurance against the loss of any of these individuals.

We have an active Board of Directors that meets at least quarterly throughout the year and is closely involved in 
our business and the determination of our operational strategies. Members of our Board of Directors work closely
with management to identify potential prospects, acquisitions and areas for further development. If any of our
directors resign or become unable to continue in their present role, it may be difficult to find replacements with the 
same knowledge and experience and, as a result, our operations may be adversely affected.

    FORM 10-K PART I

84

MATADOR RESOURCES COMPANY  

In addition, our Board of Directors consults regularly with our special Board advisors regarding our business and

the evaluation, exploration, engineering and development of our prospects and properties. Due to the knowledge 
and experience of our special advisors, they play a key role in our multi-disciplined approach to making decisions 
regarding prospects, acquisitions and development. If any of our special advisors resign or become unable to 
continue in their present role, our operations may be adversely affected.

If we fail to maintain effective internal control over financial reporting in the future, our ability to accurately 
report our financial results could be adversely affected.

As a public company with listed equity securities, we are required to comply with laws, regulations and
requirements, certain corporate governance provisions of the Sarbanes-Oxley Act of 2002, related regulations of
the SEC and the requirements of the NYSE. Complying with these statutes, regulations and requirements is difficult 
and costly and occupies a significant amount of time of our Board of Directors and management.

Pursuant to the Sarbanes-Oxley Act, we are required to maintain internal control over financial reporting. Our 
efforts to maintain our internal controls may not be successful, and we may be unable to maintain effective controls 
over our financial processes and reporting in the future and comply with the certification and reporting obligations 
under Sections 302 and 404 of the Sarbanes-Oxley Act. Our management does not expect that our internal controls 
and disclosure controls will prevent all possible error or all fraud. Any failure to maintain effective controls could
result in material misstatements that are not prevented or detected and corrected on a timely basis, which could 
potentially subject us to sanction or investigation by the SEC, the NYSE or other regulatory authorities. Ineffective
internal controls could also cause investors to lose confidence in our reported financial information and adversely 
affect our business and our stock price.

A cyber incident could occur and result in information theft, data corruption, operational disruption or 
financial loss.

The oil and natural gas industry is dependent on digital technologies to conduct certain exploration, development, 

production, gathering, processing and financial activities. We depend on digital technology to, among other things, 
estimate oil and natural gas reserves quantities, plan, execute and analyze drilling, completion, production, gathering,
processing and disposal operations, process and record financial and operating data and communicate with
employees, shareholders, royalty owners and other third-party industry participants. Industrial control systems,
such as our supervisory control and data acquisition (SCADA) systems, control important processes and facilities
that are critical to our operations. If any of such programs or systems were to fail or create erroneous information
in our hardware or software network infrastructure or we were subject to cyberspace breaches, phishing schemes
or attacks, possible consequences include financial losses and the inability to engage in any of the aforementioned
activities. Any such consequence could have a material adverse effect on our business.

While we have experienced certain phishing schemes and efforts to access our network, we have not experienced

any material losses due to cyber incidents. However, we may suffer such losses in the future. If our systems for 
protecting against cyber incidents prove to be insufficient, we could be adversely affected by unauthorized access 
to proprietary information, which could lead to data corruption, communication interruption, exposure of our or 
third parties’ confidential or proprietary information, operational disruptions or financial loss. As cyber threats 
continue to evolve, we may be required to expend additional resources to continue to modify and enhance our
protective systems or to investigate and remediate any vulnerabilities.

Provisions of our certificate of formation, bylaws and Texas law may have anti-takeover effects that could 
prevent a change in control even if it might be beneficial to our shareholders.

Our certificate of formation and bylaws contain certain provisions that may discourage, delay or prevent a merger 

or acquisition that our shareholders may consider favorable. These provisions include:

• authorization for our Board of Directors to issue preferred stock without shareholder approval;

• a classified Board of Directors so that not all members of our Board of Directors are elected at one time;

•

the prohibition of cumulative voting in the election of directors; and

• a limitation on the ability of shareholders to call special meetings to those owning at least 25% of our

outstanding shares of common stock.

Provisions of Texas law may also discourage, delay or prevent someone from acquiring or merging with us,

which may cause the market price of our common stock to decline. Under Texas law, a shareholder who beneficially 
owns more than 20% of our voting stock, or an affiliated shareholder, cannot acquire us for a period of three years
from the date this person became an affiliated shareholder, unless various conditions are met, such as approval
of the transaction by our Board of Directors before this person became an affiliated shareholder or approval of the 
holders of at least two-thirds of our outstanding voting shares not beneficially owned by the affiliated shareholder.

We operate in a litigious environment and may be involved in legal proceedings that could have an adverse 
effect on our results of operations and financial condition.

Like many oil and natural gas companies, we are from time to time involved in various legal and other 
proceedings, such as title, royalty or contractual disputes, regulatory compliance matters and personal injury or 
property damage matters, in the ordinary course of our business. Such legal proceedings are inherently uncertain 
and their results cannot be predicted. Regardless of the outcome, such proceedings could have an adverse
impact on us because of legal costs, diversion of management and other personnel and other factors. In addition, 
it is possible that a resolution of one or more such proceedings could result in liability, penalties or sanctions, as 
well as judgments, consent decrees or orders requiring a change in our business practices, which could materially 
and adversely affect our business, operating results and financial condition. Accruals for such liability, penalties
or sanctions may be insufficient. Judgments and estimates to determine accruals or range of losses related to legal
and other proceedings could change from one period to the next, and such changes could be material.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND  

RESULTS OF OPERATIONS.

The following discussion and analysis of our financial condition and results of operations should be read in

conjunction with our consolidated financial statements and related notes appearing elsewhere in this Annual Report.
The following discussion contains “forward-looking statements” that reflect our future plans, estimates, beliefs and 
expected performance. We caution that assumptions, expectations, projections, intentions or beliefs about future 
events may, and often do, vary from actual results, and the differences can be material. Some of the key factors that 
could cause actual results to vary from our expectations include changes in oil or natural gas prices, the timing of 
planned capital expenditures, availability under our Credit Agreement and the San Mateo Credit Facility, uncertainties 
in estimating proved reserves and forecasting production results, operational factors affecting our oil and 
natural gas and midstream operations, the condition of the capital markets generally, as well as our ability to access 
them, the impact of the worldwide spread of COVID-19 on oil and natural gas demand, oil and natural gas prices 
and our business, the proximity to and capacity of gathering, processing and transportation facilities, availability and 
integration of acquisitions, uncertainties regarding environmental regulations or litigation and other legal or 
regulatory developments affecting our business, as well as those factors discussed below and elsewhere in this 
Annual Report, all of which are difficult to predict. In light of these risks, uncertainties and assumptions, the forward-
looking events discussed may not occur. See “Cautionary Note Regarding Forward-Looking Statements.”

For a comparison of our results of operations for the years ended December 31, 2019 and December 31, 2018,
see “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report 
on Form 10-K for the year ended December 31, 2019, filed with the SEC on March 2, 2020.

OVERVIEW

We are an independent energy company founded in July 2003 engaged in the exploration, development, 

production and acquisition of oil and natural gas resources in the United States, with an emphasis on oil and natural 
gas shale and other unconventional plays. Our current operations are focused primarily on the oil and liquids-rich
portion of the Wolfcamp and Bone Spring plays in the Delaware Basin in Southeast New Mexico and West Texas. 
We also operate in the Eagle Ford shale play in South Texas and the Haynesville shale and Cotton Valley plays in 
Northwest Louisiana. Additionally, we conduct midstream operations, primarily through San Mateo, in support of our 
exploration, development and production operations and provide natural gas processing, oil transportation services, 
oil, natural gas and produced water gathering services and produced water disposal services to third parties.

2020 Operational Highlights

During the first quarter and through April 2020, the oil and natural gas industry witnessed an abrupt and

significant decline in oil prices from $63 per Bbl in early January to as low as ($38) per Bbl in late April. This sudden
decline in oil prices was attributable to two primary factors: (i) the precipitous decline in global oil demand resulting
from the worldwide spread of COVID-19 and (ii) a sudden, unexpected increase in global oil supply resulting from
actions initiated by Saudi Arabia to increase its oil production to world markets following the failure of efforts
by OPEC+ to agree on coordinated production cuts at their March 6, 2020 meetings in Vienna, Austria. Primarily 
as a result of these unexpected events and the resulting declines in oil prices, we significantly modified our 
2020 operational plan.

2020 ANNUAL REPORT

We began 2020 operating six drilling rigs in the Delaware Basin, as we continued to focus on the exploration,
delineation and development of our Delaware Basin acreage in Loving County, Texas and Lea and Eddy Counties,
New Mexico. We had originally planned to operate these six drilling rigs in the Delaware Basin throughout 2020. 
As a result of the events noted above, however, we released (i) one operated drilling rig from our Wolf asset area 
late in the first quarter of 2020, (ii) a second operated drilling rig from the Greater Stebbins Area in late April 2020
and (iii) a third operated drilling rig from our Rustler Breaks asset area in late June 2020. We operated three 
drilling rigs in the Delaware Basin during the remainder of 2020. Two of these rigs operated primarily in the Stateline 
asset area, and the third rig operated primarily in the Rustler Breaks asset area and in the Rodney Robinson 
leasehold in the western portion of the Antelope Ridge asset area during the second half of 2020.

During the year ended December 31, 2020, we completed and began producing oil and natural gas from 53 gross 

(45.6 net) operated and 36 gross (2.2 net) non-operated wells in the Delaware Basin. We did not conduct any
operated drilling and completion activities on our leasehold properties in South Texas or Northwest Louisiana during 
2020, although we did participate in the drilling and completion of four gross (less than 0.1 net) non-operated 
Haynesville shale wells that began producing in 2020.

The vast majority of our 2020 capital expenditures was directed to (i) the delineation and development of our 
leasehold position in the Delaware Basin, (ii) the development of certain midstream assets to support our operations 
there, (iii) our participation in non-operated wells drilled and completed in the Delaware Basin and (iv) the acquisition
of additional leasehold and mineral interests prospective for the Wolfcamp, Bone Spring and other liquids-rich
plays in the Delaware Basin. Our remaining capital expenditures were primarily directed to the installation of pumping 
units and other facilities on certain of our Eagle Ford shale wells in South Texas and to our participation in several 
non-operated wells drilled and completed in the Haynesville shale throughout 2020.

Our average daily oil equivalent production for the year ended December 31, 2020 was 75,175 BOE per day,

including 43,526 Bbl of oil per day and 189.9 MMcf of natural gas per day, an increase of 14%, as compared to 
66,203 BOE per day, including 38,312 Bbl of oil per day and 167.4 MMcf of natural gas per day, for the year ended
December 31, 2019. Our average daily oil production in 2020 of 43,526 Bbl of oil per day increased 14% from
38,312 Bbl of oil per day in 2019. This increase in oil production was primarily a result of our ongoing delineation and 
development drilling activities in the Delaware Basin, which offset declining oil production in the Eagle Ford shale 
where we have not turned to sales any new operated wells since the second quarter of 2019. Our average daily
natural gas production of 189.9 MMcf per day in 2020 increased 13% from 167.4 MMcf per day in 2019. This increase 
in natural gas production was primarily attributable to our ongoing delineation and development drilling activities in
the Delaware Basin, which offset declining natural gas production in the Haynesville shale where we had
significantly less non-operated activity in 2020 as compared to 2019. Oil production comprised 58% of our total 
production for each of the years ended December 31, 2020 and December 31, 2019.

For the year ended December 31, 2020, our oil and natural gas revenues were $744.5 million, a decrease of 17% 

from oil and natural gas revenues of $892.3 million for the year ended December 31, 2019. Our oil revenues 
decreased 22% to approximately $595.5 million, as compared to $759.8 million for the year ended December 31, 2019. 
The decrease in oil revenues resulted from a lower weighted average realized oil price of $37.38 per Bbl in 2020,
as compared to $54.34 per Bbl in 2019. This decrease was partially offset by the 14% increase in oil production for 
the year ended December 31, 2020 noted above. Our natural gas revenues increased 12% to approximately
$149.0 million, as compared to $132.5 million for the year ended December 31, 2019. The increase in natural gas 
revenues primarily resulted from the 13% increase in our natural gas production noted above.

We reported a net loss attributable to Matador shareholders of approximately $593.2 million, or ($5.11) per
diluted common share, on a GAAP basis for the year ended December 31, 2020, as compared to net income of
$87.8 million, or $0.75 per diluted common share, for the year ended December 31, 2019. Adjusted EBITDA for 
the year ended December 31, 2020 was $519.3 million, as compared to Adjusted EBITDA of $610.8 million for the
year ended December 31, 2019. Adjusted EBITDA is a non-GAAP financial measure. For a definition of Adjusted
EBITDA and a reconciliation of Adjusted EBITDA to our net income (loss) and net cash provided by operating 
activities, see “Selected Financial Data—Non-GAAP Financial Measures.”

At December 31, 2020, our estimated total proved oil and natural gas reserves were 270.3 million BOE, including 

159.9 million Bbl of oil and 662.3 Bcf of natural gas, with a Standardized Measure of $1.58 billion and a PV-10 of
$1.66 billion. At December 31, 2019, our estimated total proved oil and natural gas reserves were 252.5 million 
BOE, including 148.0 million Bbl of oil and 627.2 Bcf of natural gas, with a Standardized Measure of $2.03 billion and
a PV-10 of $2.25 billion. Our estimated total proved reserves of 270.3 million BOE at December 31, 2020
represented a 7% year-over-year increase, as compared to 252.5 million BOE at December 31, 2019. Our estimated
proved oil reserves of 159.9 million Bbl at December 31, 2020 increased 8%, as compared to 148.0 million Bbl
at December 31, 2019. Proved oil reserves comprised 59% of our total proved reserves at both December 31, 2020
and December 31, 2019. At December 31, 2020, 46% of our total proved reserves were proved developed
reserves, as compared to 42% at December 31, 2019.

Our proved oil and natural gas reserves in the Delaware Basin increased 12% to 261.9 million BOE at

December 31, 2020, as compared to 232.8 million BOE at December 31, 2019, primarily as a result of our ongoing 
delineation and development operations there. At December 31, 2020, approximately 97% of our total proved
oil and natural gas reserves were attributable to our properties in the Delaware Basin. Our proved oil reserves in the
Delaware Basin increased 12% to 156.3 million Bbl at December 31, 2020, as compared to 139.6 million Bbl
at December 31, 2019. Proved oil reserves comprised 60% of our Delaware Basin total proved reserves at both 
December 31, 2020 and December 31, 2019.

At both December 31, 2020 and December 31, 2019, these reserves estimates were based on evaluations 

prepared by our engineering staff and have been audited for their reasonableness and conformance with 
SEC guidelines by Netherland, Sewell & Associates, Inc., independent reservoir engineers. Standardized Measure
represents the present value of estimated future net cash flows from proved reserves, less estimated future
development, production, plugging and abandonment costs and income tax expenses, discounted at 10% per
annum to reflect the timing of future cash flows. Standardized Measure is not an estimate of the fair market 
value of our properties. PV-10 is a non-GAAP financial measure. For a reconciliation of PV-10 to Standardized
Measure, see “Business—Estimated Proved Reserves.”

2020 Midstream Highlights

Effective October 1, 2020, together with our joint venture partner, Five Point, we completed the successful

merger of San Mateo II with and into San Mateo I. San Mateo is owned 51% by us and 49% by Five Point.

San Mateo achieved strong operating results in 2020, highlighted by (i) increased midstream services revenues,

(ii) increased produced water handling volumes and (iii) increased oil gathering and transportation volumes, 
all as compared to 2019. San Mateo’s natural gas gathering and processing volumes declined slightly in 2020 as
compared to 2019 due to reduced volumes from a significant third-party customer, but, on a quarterly sequential 
basis, San Mateo’s natural gas gathering and processing volumes, produced water handling volumes and oil
gathering and transportation volumes all increased significantly in the fourth quarter of 2020, as compared to the
third quarter, as we realized the first full quarter of production from the Boros wells in the Stateline asset area
and the Leatherneck wells in the Greater Stebbins Area.

During the third quarter of 2020, San Mateo completed the construction and successful start-up of the 
expansion of the Black River Processing Plant, which added an incremental designed inlet capacity of 200 MMcf of
natural gas per day to the previously designed inlet capacity of 260 MMcf per day for a total designed inlet capacity 
of 460 MMcf per day. The expanded Black River Processing Plant supports our exploration and development 
activities in the Delaware Basin and, at December 31, 2020, was gathering and processing natural gas from the
Stateline asset area and from the Greater Stebbins Area. The Black River Processing Plant also processes natural
gas from our Rustler Breaks asset area and provides natural gas processing services for other San Mateo customers 
in the area.

In September 2020, San Mateo also completed and placed in service approximately 43 miles of large diameter 
natural gas gathering pipelines between the Black River Processing Plant and the Stateline asset area (approximately 
24 miles) and the Greater Stebbins Area (approximately 19 miles). In addition, San Mateo completed and placed in 
service approximately 19 miles of various diameter crude oil pipelines from certain points of origin in the Greater 
Stebbins Area to the existing San Mateo interconnect with Plains in Eddy County, New Mexico. At December 31, 2020,
San Mateo was gathering or transporting our oil and natural gas production via pipeline in both the Stateline asset
area and the Greater Stebbins Area, as well as in the Wolf and Rustler Breaks asset areas. San Mateo was handling 
our produced water in each of these areas as well.

At December 31, 2020, San Mateo’s midstream system included:

• Natural Gas Assets: 460 MMcf per day of designed natural gas cryogenic processing capacity and

approximately 140 miles of natural gas gathering pipelines in Eddy County, New Mexico and Loving County, 
Texas, including 43 miles of large diameter natural gas gathering lines spanning from the Stateline asset
area to the Greater Stebbins Area in Eddy County, New Mexico;

• Oil Assets: Three oil CDPs with over 100,000 Bbl of designed oil throughput capacity and approximately
90 miles of oil gathering and transportation pipelines in Eddy County, New Mexico and Loving County, 
Texas, as well as a 400,000-acre joint development area with Plains to gather our and other producers’ oil 
production in Eddy County, New Mexico; and

• Produced Water Assets: 13 commercial salt water disposal wells and associated facilities with designed

produced water disposal capacity of 335,000 Bbl per day and approximately 120 miles of produced water 
gathering pipelines in Eddy County, New Mexico and Loving County, Texas.

MATADOR RESOURCES COMPANY  

2021 Capital Expenditure Budget

We expect that development of our Delaware Basin assets will be the primary focus of our operations and 
capital expenditures in 2021. We plan to operate three contracted drilling rigs in the Delaware Basin for most of the 
first quarter of 2021. In March 2021, we plan to add a fourth drilling rig and operate four drilling rigs throughout 
the remainder of 2021. Our 2021 estimated capital expenditure budget consists of $525.0 to $575.0 million for drilling,
completing and equipping wells (“D/C/E capital expenditures”) and $20.0 to $30.0 million for midstream capital 
expenditures, which reflects our proportionate share of San Mateo’s estimated 2021 capital expenditures. Substantially 
all of these 2021 estimated capital expenditures are expected to be allocated to (i) the further delineation and 
development of our leasehold position, (ii) the construction, installation and maintenance of midstream assets and
(iii) our participation in certain non-operated well opportunities in the Delaware Basin, with the exception of amounts 
allocated to limited operations in our South Texas and Haynesville shale positions to maintain and extend leases 
and to participate in certain non-operated well opportunities. Our 2021 Delaware Basin operated drilling program is 
expected to focus on the continued development of our various asset areas throughout the Delaware Basin, with
a continued emphasis on drilling and completing a higher percentage of longer horizontal wells in 2021, including 
98% with anticipated completed lateral lengths of two miles or greater.

At December 31, 2020, we had $57.9 million in cash (excluding restricted cash) and $214.2 million in undrawn
borrowing capacity under the Credit Agreement (after giving effect to outstanding letters of credit based upon our 
elected borrowing commitment of $700.0 million). Excluding any possible significant acquisitions, we expect to fund
our 2021 capital expenditures through a combination of cash on hand, operating cash flows and performance
incentives paid to us by Five Point in connection with San Mateo. If capital expenditures were to exceed our
operating cash flows in 2021, we expect to fund any such excess capital expenditures through borrowings under
the Credit Agreement or the San Mateo Credit Facility (assuming availability under such facilities) or through other 
capital sources, including borrowings under additional credit arrangements, the sale or joint venture of midstream
assets, oil and natural gas producing assets, leasehold interests or mineral interests and potential issuances of
equity, debt or convertible securities, none of which may be available on satisfactory terms or at all.

We may divest portions of our non-core assets, particularly in the Haynesville shale and in our South Texas 
position (as we did in 2019 and 2020), as well as consider monetizing other assets, such as certain mineral, royalty 
and midstream interests, as value-creating opportunities arise. In addition, we intend to continue evaluating the 
opportunistic acquisition of acreage and mineral interests, principally in the Delaware Basin, during 2021. These
monetizations, divestitures and expenditures are opportunity-specific, and purchase price multiples and per-acre 
prices can vary significantly based on the asset or prospect. As a result, it is difficult to estimate these 2021 
monetizations, divestitures and capital expenditures with any degree of certainty; therefore, we have not provided 
estimated proceeds related to monetizations or divestitures or estimated capital expenditures related to acreage 
and mineral acquisitions for 2021. The aggregate amount of capital we expend may fluctuate materially based on
market conditions, the actual costs to drill, complete and place on production operated or non-operated wells, 
our drilling results, the actual costs and scope of our midstream activities, the ability of our joint venture partners to
meet their capital obligations, other opportunities that may become available to us and our ability to obtain capital.

Year Ended December 31, 2020 as Compared to Year Ended December 31, 2019

Oil and natural gas revenues. Our oil and natural gas revenues decreased $147.9 million, or 17%, to $744.5 million 

for the year ended December 31, 2020, as compared to $892.3 million for the year ended December 31, 2019.
Our oil revenues decreased $164.3 million, or 22%, to $595.5 million for the year ended December 31, 2020,
as compared to $759.8 million for the year ended December 31, 2019. This decrease in oil revenues resulted from
a 31% decrease in the weighted average oil price realized for the year ended December 31, 2020 to $37.38 per Bbl, 
as compared to $54.34 per Bbl realized for the year ended December 31, 2019. This decrease in our oil revenues
was partially offset by the 14% increase in our oil production to 15.9 million Bbl of oil for the year ended December 31, 
2020, as compared to 14.0 million Bbl of oil for the year ended December 31, 2019. The increase in oil production
was primarily attributable to our ongoing delineation and development drilling activities in the Delaware Basin,
which offset declining oil production primarily from our properties in the Eagle Ford shale. Our natural gas revenues
increased by $16.4 million, or 12%, to $149.0 million for the year ended December 31, 2020, as compared to
$132.5 million for the year ended December 31, 2019. The increase in natural gas revenues was primarily attributable 
to the 14% increase in our natural gas production to 69.5 Bcf for the year ended December 31, 2020, as compared
to 61.1 Bcf for the year ended December 31, 2019. The increase in natural gas production was primarily attributable to
our ongoing delineation and development drilling activities in the Delaware Basin, which offset declining natural
gas production primarily from our properties in the Haynesville shale.

Third-party midstream services revenues. Our third-party midstream services revenues increased

$5.8 million, or 10%, to $64.9 million for the year ended December 31, 2020, as compared to $59.1 million for the
year ended December 31, 2019. Third-party midstream services revenues are those revenues from midstream
operations related to third parties, including working interest owners in our operated wells. This increase was primarily 
attributable to (i) an increase in our third-party natural gas gathering, transportation and processing revenues to 
$30.1 million for the year ended December 31, 2020, as compared to $27.0 million for the year ended December 31, 
2019, (ii) an increase in our third-party oil gathering and transportation revenues to $9.4 million for the year ended
December 31, 2020, as compared to $7.2 million for the year ended December 31, 2019, and (iii) an increase in
third-party produced water handling revenues to $25.5 million for the year ended December 31, 2020, as compared
to $24.9 million for the year ended December 31, 2019.

Sales of purchased natural gas. Our sales of purchased natural gas decreased $33.0 million, or 44%, to

$41.7 million for the year ended December 31, 2020, as compared to $74.8 million for the year ended December 31, 
2019. This decrease was primarily the result of a decrease in natural gas volumes sold during the year ended 
December 31, 2020. Sales of purchased natural gas primarily reflect those natural gas purchase transactions that
we periodically enter into with third parties whereby we purchase natural gas and (i) subsequently sell the natural 
gas to other purchasers or (ii) process the natural gas at the Black River Processing Plant and subsequently sell the
residue gas and NGLs to other purchasers. These revenues, and the expenses related to these transactions 
included in “Purchased natural gas,” are presented on a gross basis in our consolidated statement of operations.

Lease bonus - mineral acreage. Our lease bonus - mineral acreage revenues were $4.1 million for the year

ended December 31, 2020, as compared to $1.7 million for the year ended December 31, 2019. Lease bonus - 
mineral acreage revenues reflect the payments we receive to enter into or extend leases to third-party lessees to
develop the oil and natural gas attributable to certain of our mineral interests.

Realized gain on derivatives. Our realized net gain on derivatives was $38.9 million for the year ended 

December 31, 2020, as compared to a realized net gain of approximately $9.5 million for the year ended December 31, 
2019. We realized a net gain of $35.1 million related to our oil costless collar, put and swap contracts for the year
ended December 31, 2020, resulting primarily from oil prices that were below the floor prices of certain of our oil 
costless collar contracts and below the strike price of certain of our oil put and swap contracts. We realized a net 
gain of $3.8 million from our oil basis swap contracts for the year ended December 31, 2020, resulting from oil basis 
prices that were lower than the fixed prices of certain of our oil basis swap contracts. We realized net gains of
$8.9 million and $0.5 million from our oil and natural gas costless collar contracts, respectively, for the year ended
December 31, 2019, resulting from oil and natural gas prices that were below the floor prices of certain of our oil
and natural gas costless collar contracts. We realized a net gain of $0.1 million from our oil basis swap contracts for
the year ended December 31, 2019, resulting from oil basis prices that were lower than the fixed prices of certain 
of our oil basis swap contracts. We realized an average gain on our oil derivatives of approximately $2.45 per Bbl of 
oil produced during the year ended December 31, 2020, as compared to an average gain of $0.64 per Bbl of oil
produced during the year ended December 31, 2019. Our total oil volumes hedged for the year ended December 31, 
2020 represented 77% of our total oil production, as compared to 59% of our total oil production for the year
ended December 31, 2019. Our total natural gas volumes hedged for the year ended December 31, 2020 
represented 10% of our total natural gas production, as compared to 12% of our total natural gas production for the
year ended December 31, 2019.

Unrealized (loss) gain on derivatives. Our unrealized loss on derivatives was approximately $32.0 million for 

the year ended December 31, 2020, as compared to an unrealized loss of $53.7 million for the year ended
December 31, 2019. During the year ended December 31, 2020, the aggregate net fair value of our open oil and
natural gas derivatives and oil basis swap contracts decreased from a net liability of approximately $3.9 million to a
net liability of approximately $35.9 million, resulting in an unrealized loss on derivatives of approximately $32.0 
million for the year ended December 31, 2020. During the year ended December 31, 2019, the aggregate net fair

2020 ANNUAL REPORT

97    

value of our open oil and natural gas derivative and oil basis swap contracts decreased from a net asset of
approximately $49.8 million to a net liability of approximately $3.9 million, resulting in an unrealized loss on
derivatives of approximately $53.7 million for the year ended December 31, 2019.

Year Ended December 31, 2020 as Compared to Year Ended December 31, 2019

Production taxes, transportation and processing. Our production taxes and transportation and processing

expenses increased $1.1 million, or 1%, to $93.3 million for the year ended December 31, 2020, as compared
to $92.3 million for the year ended December 31, 2019. This increase was primarily attributable to the $11.0 million 
increase in transportation and processing expenses to $40.0 million for the year ended December 31, 2020, as
compared to $29.0 million for the year ended December 31, 2019, primarily resulting from the 14% increase in total oil
equivalent production between the respective periods. This increase in transportation and processing expenses was 
largely offset by a $9.9 million decrease in our production taxes to $53.4 million for the year ended December 31,
2020, as compared to $63.3 million for the year ended December 31, 2019, resulting from the $147.9 million
decrease in oil and natural gas revenues for the year ended December 31, 2020, as compared to the year ended 
December 31, 2019. On a unit-of-production basis, our production taxes and transportation and processing expenses 
decreased 11% to $3.39 per BOE for the year ended December 31, 2020, as compared to $3.82 per BOE for
the year ended December 31, 2019, as the 14% increase in total oil equivalent production between the respective 
periods more than offset the 1% increase in our production taxes, transportation and processing expenses.

MATADOR RESOURCES COMPANY  

Lease operating expenses. Our lease operating expenses decreased $12.4 million, or 11%, to $105.0 million 

for the year ended December 31, 2020, as compared to $117.3 million for the year ended December 31, 2019.
On a unit-of-production basis, our lease operating expenses decreased 21% to $3.81 per BOE for the year ended
December 31, 2020, as compared to $4.85 per BOE for the year ended December 31, 2019. These decreases
in our lease operating expenses for the year ended December 31, 2020 were primarily attributable to (i) a decrease 
in produced water disposal expenses of $11.4 million, (ii) a decrease in equipment rental and workover expenses 
of $4.6 million and (iii) a decrease in ad valorem taxes of $1.1 million. These decreases were partially offset by 
increases in expenses associated with compressors of $2.4 million, which were attributable to servicing the increased 
number of wells at December 31, 2020, as compared to December 31, 2019.

Plant and other midstream services operating. Our plant and other midstream services operating expenses
increased $4.7 million, or 13%, to $41.5 million for the year ended December 31, 2020, as compared to $36.8 million
for the year ended December 31, 2019. This increase was primarily attributable to (i) increased expenses
associated with our expanded commercial produced water disposal operations of $21.8 million for the year ended
December 31, 2020, as compared to $18.1 million for the year ended December 31, 2019, and (ii) increased 
expenses associated with our expanded pipeline operations of $10.0 million for the year ended December 31, 2020,
as compared to $7.9 million for the year ended December 31, 2019. These increases were partially offset by 
decreased expenses associated with operating the Black River Processing Plant of $9.7 million for the year ended
December 31, 2020, as compared to $11.0 million for the year ended December 31, 2019.

Depletion, depreciation and amortization. Our depletion, depreciation and amortization expenses increased

$11.3 million, or 3%, to $361.8 million for the year ended December 31, 2020, as compared to $350.5 million 
for the year ended December 31, 2019. This increase was primarily attributable to (i) the 14% increase in total oil 
equivalent production to 27.5 million BOE for the year ended December 31, 2020, as compared to 24.2 million BOE
for the year ended December 31, 2019, and (ii) increased depreciation expenses attributable to our midstream 
segment of approximately $23.3 million for the year ended December 31, 2020, as compared to $16.1 million for 
the year ended December 31, 2019. On a unit-of-production basis, our depletion, depreciation and amortization 
expenses decreased 9% to $13.15 per BOE for the year ended December 31, 2020, as compared to $14.51 per
BOE for the year ended December 31, 2019. On a unit-of-production basis, the decrease was primarily attributable
to the decrease in unamortized property costs resulting from the full-cost ceiling impairments recorded in the 
second and third quarters of 2020, as well as the 14% increase in total equivalent oil production during 2020.

Full-cost ceiling impairment. Due to the sharp decline in oil and natural gas prices used to estimate proved oil

and natural gas reserves in 2020, at June 30, September 30 and December 31, 2020, the net capitalized costs 
of our oil and natural gas properties less related deferred income taxes exceeded the full-cost ceiling. As a result, 
we recorded an impairment charge of $684.7 million, exclusive of tax effect, to the net capitalized costs. This
full-cost ceiling impairment is reflected in our consolidated statement of operations for the year ended December 31,
2020, with the related deferred income tax credit recorded net of a valuation allowance. No impairment to the
net carrying value of our oil and natural gas properties and no corresponding charge resulting from a full-cost ceiling 
impairment were recorded for the year ended December 31, 2019.

General and administrative. Our general and administrative expenses decreased $17.5 million, or 22%, to
$62.6 million for the year ended December 31, 2020, as compared to $80.1 million for the year ended December 31, 
2019. Our general and administrative expenses on a unit-of-production basis decreased 31% to $2.27 per BOE for 
the year ended December 31, 2020, as compared to $3.31 per BOE for the year ended December 31, 2019. These
decreases were primarily attributable to cost reductions initially implemented during the three months ended 
March 31, 2020, including headcount and employee compensation reductions, that were maintained throughout the 
remainder of 2020.

FORM 10-K PART I I

2020 ANNUAL REPORT

Interest expense. For the year ended December 31, 2020, we incurred total interest expense of approximately 
$82.2 million. We capitalized approximately $5.5 million of our interest expense on certain qualifying projects for the 
year ended December 31, 2020 and expensed the remaining $76.7 million to operations. For the year ended 
December 31, 2019, we incurred total interest expense of approximately $82.4 million. We capitalized $8.5 million 
of our interest expense on certain qualifying projects for the year ended December 31, 2019 and expensed the
remaining $73.9 million to operations.

Total income tax (benefit) provision. We recorded a total income tax benefit of $45.6 million for the year ended

December 31, 2020. As a result of the full-cost ceiling impairments that were recorded during 2020, we recorded
a valuation allowance of $110.7 million against our net deferred tax assets for the year ended December 31, 2020, 
which partially offset the income tax benefit that resulted from our $599.2 million loss before income taxes for the
year ended December 31, 2020. The valuation allowance will continue to be recognized until the realization of future 
deferred tax benefits are more likely than not to be utilized. Our effective tax rate was 7.6% for the year ended
December 31, 2020, which differed from amounts computed by applying the U.S. federal statutory tax rates to
pre-tax income due primarily to the impact of the valuation allowance, but also due to permanent differences between
book and taxable income and state taxes, primarily in New Mexico. We recorded a total income tax provision of
$35.5 million for the year ended December 31, 2019. Our effective tax rate was 22.4% for the year ended
December 31, 2019, which differed from amounts computed by applying the U.S. federal statutory tax rates to
pre-tax income due primarily to the impact of permanent differences between book and taxable income and state 
taxes, primarily in New Mexico.

LIQUIDITY AND CAPITAL RESOURCES

Our primary use of capital has been, and we expect will continue to be during 2021 and for the foreseeable

future, for the acquisition, exploration and development of oil and natural gas properties and for midstream
investments. Excluding any possible significant acquisitions, we expect to fund our capital expenditures for 2021
primarily through a combination of cash on hand, operating cash flows and performance incentives paid to us 
by Five Point in connection with San Mateo. If capital expenditures were to exceed our operating cash flows in 2021,
we expect to fund any such excess capital expenditures through borrowings under the Credit Agreement or the
San Mateo Credit Facility (assuming availability under such facilities) or through other capital sources, including 
borrowings under additional credit arrangements, the sale or joint venture of midstream assets, oil and natural gas
producing assets, leasehold interests or mineral interests and potential issuances of equity, debt or convertible 
securities, none of which may be available on satisfactory terms or at all. Our future success in growing proved
reserves and production will be highly dependent on our ability to generate operating cash flows and access outside
sources of capital.

At December 31, 2020, we had cash totaling $57.9 million and restricted cash totaling $33.5 million, which was
associated with San Mateo. By contractual agreement, the cash in the accounts held by our less-than-wholly-owned
subsidiaries is not to be commingled with our other cash and is to be used only to fund the capital expenditures
and operations of these less-than-wholly-owned subsidiaries.

At December 31, 2020, we had (i) $1.05 billion of outstanding 5.875% senior notes due September 2026 (the
“Notes”), (ii) $440.0 million in borrowings outstanding under the Credit Agreement, (iii) approximately $45.8 million
in outstanding letters of credit issued pursuant to the Credit Agreement and (iv) $7.5 million outstanding under
an unsecured U.S. Small Business Administration (“SBA”) loan. In February 2020, the lenders under the Credit
Agreement completed their review of our proved oil and natural gas reserves, and, as a result, the borrowing 
base was reaffirmed at $900.0 million. We elected to increase the borrowing commitment from $500.0 million to

  FORM 10-K PART I I

 
 
100

MATADOR RESOURCES COMPANY 

$700.0 million, and the maximum facility amount remained $1.5 billion. We also added two new banks to our 
lending group as part of this redetermination process. This February 2020 redetermination constituted the regularly
scheduled May 1 redetermination. In October 2020, the lenders under our Credit Agreement completed their review 
of our proved oil and natural gas reserves, and, as a result, the borrowing base was reaffirmed at $900.0 million.
We elected to keep the borrowing commitment at $700.0 million, the maximum facility amount remained $1.5 billion
and no changes were made to the terms of the Credit Agreement. This October 2020 redetermination constituted 
the regularly scheduled November 1 redetermination. Borrowings under the Credit Agreement are limited to the
lowest of the borrowing base, the maximum facility amount and the elected commitment (subject to compliance
with the covenant noted below). The Credit Agreement matures in October 2023. The Credit Agreement requires
the Company to maintain a debt to EBITDA ratio, which is defined as debt outstanding (net of up to $50.0 million of 
cash or cash equivalents), divided by a rolling four quarter EBITDA calculation, of 4.00 or less. We believe that we
were in compliance with the terms of the Credit Agreement at December 31, 2020. Between December 31, 2020
and February 23, 2021, we repaid an additional $10.0 million of borrowings outstanding under the Credit Agreement.

At December 31, 2020, San Mateo had $334.0 million in borrowings outstanding under the San Mateo Credit

Facility and approximately $9.0 million in outstanding letters of credit issued pursuant to the San Mateo Credit
Facility. The San Mateo Credit Facility includes an accordion feature, which provides for potential increases to up to 
$400.0 million, and matures in December 2023. At December 31, 2020, the lender commitments under the 
San Mateo Credit Facility were $375.0 million (subject to San Mateo’s compliance with the covenants noted below). 
The San Mateo Credit Facility is guaranteed by San Mateo’s subsidiaries, secured by substantially all of 
San Mateo’s assets, including real property, and is non-recourse with respect to Matador and its wholly-owned 
subsidiaries. The San Mateo Credit Facility requires San Mateo to maintain a debt to EBITDA ratio, which is defined 
as total consolidated funded indebtedness outstanding (as defined in the San Mateo Credit Facility) divided by a
rolling four quarter EBITDA calculation, of 5.00 or less, subject to certain exceptions. The San Mateo Credit Facility 
also requires San Mateo to maintain an interest coverage ratio, which is defined as a rolling four quarter EBITDA
calculation divided by San Mateo’s consolidated interest expense for such period, of 2.50 or more. The San Mateo 
Credit Facility also restricts the ability of San Mateo to distribute cash to its members if San Mateo’s liquidity
is less than 10% of the lender commitments under the San Mateo Credit Facility. We believe that San Mateo 
was in compliance with the terms of the San Mateo Credit Facility at December 31, 2020. Between December 31, 
2020 and February 23, 2021, we repaid an additional $11.0 million of borrowings outstanding under the
San Mateo Credit Facility.

During the first quarter and through April 2020, the oil and natural gas industry witnessed an abrupt and 

significant decline in oil prices from $63 per Bbl in early January to as low as ($38) per Bbl in late April, although oil
prices began to improve later in the second quarter and throughout the remainder of 2020. This sudden decline
in oil prices was attributable to two primary factors: (i) the precipitous decline in global oil demand resulting from the 
worldwide spread of COVID-19 and (ii) a sudden, unexpected increase in global oil supply resulting from actions
initiated by Saudi Arabia to increase its oil production to world markets following the failure of efforts by members
of OPEC+ to agree on coordinated production cuts at their March 6, 2020 meetings in Vienna, Austria.

Primarily as a result of these unexpected events and the resulting declines in oil prices, we modified our 2020

operational plan. In March 2020, we significantly reduced our capital expenditure budget, including reducing 
our operated drilling program from six to three drilling rigs by the end of the second quarter of 2020. In addition,
we made initial reductions to headcount, employee salaries and lease operating expenses and curtailed or shut 
in portions of our oil and natural gas production. While we had prepared to make further reductions to headcount,
salaries and our capital expenditure budget, we have been able to avoid such reductions to date as a result of 

FORM 10-K PART I I

2020 ANNUAL REPORT

101    

realizing greater-than-expected savings from the above changes to our 2020 operational plan, restructuring our
hedge portfolio and applying for and receiving an SBA loan through the Paycheck Protection Program. While oil prices 
have continued to improve into 2021, the general outlook for the oil and natural gas industry for the remainder of the 
year remains highly uncertain, and we can provide no assurances as to when or to what extent the economic disruptions 
resulting from COVID-19 and the corresponding decline in oil demand may improve. These economic disruptions have 
also significantly reduced our ability to access the capital markets on reasonably similar terms as were available
in prior periods.

As noted above, on April 13, 2020, we executed a promissory note evidencing an unsecured loan in the amount 

of approximately $7.5 million as part of the Paycheck Protection Program. The Paycheck Protection Program was 
established under the Coronavirus Aid, Relief, and Economic Security Act and is administered by the SBA. The loan 
was issued through Iberiabank, which is a lender under the Credit Agreement, matures on the second anniversary
of the funding date and bears interest at a fixed rate of 1.00% per annum. We used the proceeds of the loan for 
payroll, including salaries, payroll taxes and employee medical benefits, as permitted by the program. The receipt of 
the loan allowed us to avoid the planned further reductions to employee headcount and salaries discussed above.
The loan is eligible for forgiveness for the portion of the loan proceeds used for payroll costs and other designated 
operating expenses, provided at least 60% of the loan’s proceeds are used for payroll costs.

We expect that development of our Delaware Basin assets will be the primary focus of our operations and capital 

expenditures in 2021. We plan to operate three contracted drilling rigs in the Delaware Basin for most of the first
quarter of 2021. In March 2021, we plan to add a fourth drilling rig and operate four drilling rigs throughout the 
remainder of 2021. Our 2021 estimated capital expenditure budget consists of $525.0 to $575.0 million for D/C/E 
capital expenditures and $20.0 to $30.0 million for midstream capital expenditures, which reflects our proportionate
share of San Mateo’s estimated 2021 capital expenditures. Substantially all of these 2021 estimated capital
expenditures are expected to be allocated to (i) the further delineation and development of our leasehold position, 
(ii) the construction, installation and maintenance of midstream assets and (iii) our participation in certain non-operated
well opportunities in the Delaware Basin, with the exception of amounts allocated to limited operations in our
South Texas and Haynesville shale positions to maintain and extend leases and to participate in certain non-operated 
well opportunities. Our 2021 Delaware Basin operated drilling program is expected to focus on the continued
development of our various asset areas throughout the Delaware Basin, with a continued emphasis on drilling and 
completing a higher percentage of longer horizontal wells in 2021, including 98% with anticipated completed 
lateral lengths of two miles or greater. We have built significant optionality into our drilling program, which allowed 
us to decrease the number of rigs in 2020 from six to three within a few months and should generally allow us
to increase or decrease the number of rigs we operate as necessary based on changing commodity prices and 
other factors.

We may divest portions of our non-core assets, particularly in the Eagle Ford shale in South Texas and the

Haynesville shale in Northwest Louisiana, as well as consider monetizing other assets, such as certain mineral, royalty
and midstream interests, as value-creating opportunities arise. In addition, we intend to continue evaluating
the opportunistic acquisition of acreage and mineral interests, principally in the Delaware Basin, during 2021. These
monetizations, divestitures and expenditures are opportunity-specific, and purchase price multiples and per-acre 
prices can vary significantly based on the asset or prospect. As a result, it is difficult to estimate these 2021 
monetizations, divestitures and capital expenditures with any degree of certainty; therefore, we have not provided 
estimated proceeds related to monetizations or divestitures or estimated capital expenditures related to acreage
and mineral acquisitions for 2021.

MATADOR RESOURCES COMPANY 

Our 2021 capital expenditures may be adjusted as business conditions warrant and the amount, timing and 
allocation of such expenditures is largely discretionary and within our control. The aggregate amount of capital we
will expend may fluctuate materially based on market conditions, the actual costs to drill, complete and place
on production operated or non-operated wells, our drilling results, the actual costs and scope of our midstream
activities, the ability of our joint venture partners to meet their capital obligations, other opportunities that may 
become available to us and our ability to obtain capital. When oil or natural gas prices decline, or costs increase
significantly, we have the flexibility to defer a significant portion of our capital expenditures until later periods to
conserve cash or to focus on projects that we believe have the highest expected returns and potential to generate
near-term cash flows. We routinely monitor and adjust our capital expenditures in response to changes in prices, 
availability of financing, drilling, completion and acquisition costs, industry conditions, the timing of regulatory 
approvals, the availability of rigs, success or lack of success in our exploration and development activities, contractual 
obligations, drilling plans for properties we do not operate and other factors both within and outside our control.

Exploration and development activities are subject to a number of risks and uncertainties, which could cause
these activities to be less successful than we anticipate. A significant portion of our anticipated cash flows from
operations for 2021 is expected to come from producing wells and development activities on currently proved
properties in the Wolfcamp and Bone Spring plays in the Delaware Basin, the Eagle Ford shale in South Texas and
the Haynesville shale in Northwest Louisiana. Our existing wells may not produce at the levels we are forecasting 
and our exploration and development activities in these areas may not be as successful as we anticipate.
Additionally, our anticipated cash flows from operations are based upon current expectations of oil and natural 
gas prices for 2021 and the hedges we currently have in place. For a discussion of our expectations of such 
commodity prices, see “—General Outlook and Trends” below. We use commodity derivative financial instruments 
at times to mitigate our exposure to fluctuations in oil, natural gas and NGL prices and to partially offset reductions
in our cash flows from operations resulting from declines in commodity prices. See Note 12 to the consolidated
financial statements in this Annual Report for a summary of our open derivative financial instruments at December 31, 
2020. See “Risk Factors—Risks Related to our Financial Condition—Our exploration, development, exploitation 
and midstream projects require substantial capital expenditures that may exceed our cash flows from operations and 
potential borrowings, and we may be unable to obtain needed capital on satisfactory terms, which could adversely 
affect our future growth,” “Risk Factors—Risks Related to our Operations—Drilling for and producing oil and
natural gas are highly speculative and involve a high degree of operational and financial risk, with many uncertainties 
that could adversely affect our business,” “Risk Factors—Risks Related to our Operations—Our identified drilling 
locations are scheduled over several years, making them susceptible to uncertainties that could materially alter the
occurrence or timing of their drilling” and “Risk Factors—Risks Related to Laws and Regulations—Approximately 
28% of our leasehold and mineral acres in the Delaware Basin is located on federal lands, which are subject
to administrative permitting requirements and potential federal legislation, regulation and orders that may limit or
restrict oil and natural gas operations on federal lands.”

Cash Flows Provided by Operating Activities

Net cash provided by operating activities decreased by $74.5 million to $477.6 million for the year ended 

December 31, 2020, as compared to net cash provided by operating activities of $552.0 million for the year ended 
December 31, 2019. Excluding changes in operating assets and liabilities, net cash provided by operating activities 
decreased to $500.7 million for the year ended December 31, 2020 from $586.6 million for the year ended 
December 31, 2019. This decrease was primarily attributable to significantly lower realized oil prices for the year
ended December 31, 2020, as compared to the year ended December 31, 2019. Changes in our operating assets
and liabilities between December 31, 2019 and December 31, 2020 resulted in a net increase of approximately
$11.4 million in net cash provided by operating activities for the year ended December 31, 2020, as compared to
the year ended December 31, 2019.

Our operating cash flows are sensitive to a number of variables, including changes in our production and 

the volatility of oil and natural gas prices between reporting periods. Regional and worldwide economic activity, the
actions of OPEC+ and other large state-owned oil producers, weather, infrastructure capacity to reach markets
and other variable factors significantly impact the prices of oil and natural gas. Furthermore, the continued effect of 
COVID-19 and the corresponding decline in oil demand may also significantly impact the prices we receive for 
our oil production. These factors are beyond our control and are difficult to predict. We use commodity derivative
financial instruments to mitigate our exposure to fluctuations in oil, natural gas and NGL prices. For additional
information on the impact of changing prices on our financial condition, see “Quantitative and Qualitative Disclosures 
About Market Risk.” See also “Risk Factors—Risks Related to Our Financial Condition—Our success is
dependent on the prices of oil and natural gas. Low oil and natural gas prices and the continued volatility in these
prices may adversely affect our financial condition and our ability to meet our capital expenditure requirements
and financial obligations.”

Cash Flows Used in Investing Activities

Net cash used in investing activities decreased by $128.3 million to $775.7 million for the year ended December 31,

2020 from $904.0 million for the year ended December 31, 2019. This decrease in net cash used in investing
activities was primarily attributable to a decrease of $208.3 million in D/C/E capital expenditures as compared to the
year ended December 31, 2019, which was partially offset by (i) an increase of approximately $42.3 million in 
expenditures for midstream support equipment and facilities, which included the construction of the further expansion
of the Black River Processing Plant and associated infrastructure, additional salt water disposal wells and additional
pipeline infrastructure, (ii) an increase of $22.0 million in expenditures related to acquisition of oil and natural
gas properties and (iii) a decrease of $17.1 million in proceeds from sales of assets. Cash used for D/C/E capital 
expenditures for the year ended December 31, 2020 was primarily attributable to our operated and non-operated 
drilling and completion activities in the Delaware Basin.

Cash Flows Provided by Financing Activities

Net cash provided by financing activities was $324.3 million for the year ended December 31, 2020, as compared

to net cash provided by financing activities of $333.1 million for the year ended December 31, 2019. The net cash 
provided by financing activities for the year ended December 31, 2020 was primarily attributable to net borrowings 
under our Credit Agreement of $185.0 million, borrowings under the San Mateo Credit Facility of $46.0 million, 
net contributions related to the formation of San Mateo I and from non-controlling interest owners of less-than-
wholly-owned subsidiaries of $88.8 million and receipt of the $7.5 million SBA loan.

See Note 7 to the consolidated financial statements in this Annual Report for a summary of our debt, including 

the Credit Agreement, the San Mateo Credit Facility and the Notes.

Guarantor Financial Information

The Notes are jointly and severally guaranteed by certain subsidiaries of Matador (the “Guarantor Subsidiaries”) 

on a full and unconditional basis (except for customary release provisions). At December 31, 2020, the Guarantor 
Subsidiaries were 100% owned by Matador. Matador is a parent holding company and has no independent assets 
or operations, and there are no significant restrictions on the ability of Matador to obtain funds from the 
Guarantor Subsidiaries by dividend or loan. San Mateo and its subsidiaries are not guarantors of the Notes.

The following tables present summarized financial information of Matador (as issuer of the Notes) and the

Guarantor Subsidiaries on a combined basis after elimination of (i) intercompany transactions and balances between 
the parent and the Guarantor Subsidiaries and (ii) equity in earnings from and investments in any subsidiary that
is a non-guarantor (in thousands). This financial information is presented in accordance with the amended 
requirements of Rule 3-10 of Regulation S-X. The following financial information may not necessarily be indicative

Non-GAAP Financial Measures

We define Adjusted EBITDA attributable to Matador shareholders (“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 cash flows as determined
by GAAP. Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and external
users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies.

Management believes Adjusted EBITDA is necessary because it allows us to evaluate our operating performance

and compare the results of operations from period to period without regard to our financing methods or capital
structure. We exclude the items listed above from net income (loss) in calculating Adjusted EBITDA because these
amounts can vary substantially from company to company within our industry depending upon accounting methods
and book values of assets, capital structures and the method by which certain assets were acquired.

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 a primary indicator of our
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. Our 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 our 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.

For the year ended December 31, 2020, we reported a net loss attributable to Matador shareholders of 

$593.2 million, as compared to net income attributable to Matador shareholders of $87.8 million for the year ended 
December 31, 2019. This decrease primarily resulted from (i) significantly lower realized oil prices, partially
offset by higher oil and natural gas production, for the year ended December 31, 2020, as compared to the year
ended December 31, 2019, and (ii) the full-cost ceiling impairment of $684.7 million we recorded for the year ended 
December 31, 2020. In addition, we recorded an unrealized loss on derivatives of $32.0 million for the year ended
December 31, 2020, as compared to an unrealized loss on derivatives of $53.7 million for the year ended December 31, 
2019, and we recorded an income tax benefit of $45.6 million for the year ended December 31, 2020, as compared
to an income tax provision of $35.5 million for the year ended December 31, 2019.

Adjusted EBITDA, a non-GAAP financial measure, decreased $91.5 million to $519.3 million for the year ended

December 31, 2020, as compared to $610.8 million for the year ended December 31, 2019. This decrease was 
primarily attributable to significantly lower realized oil prices, partially offset by higher oil and natural gas production,
for the year ended December 31, 2020, as compared to the year ended December 31, 2019.

OFF-BALANCE SHEET ARRANGEMENTS

From time-to-time, we enter into off-balance sheet arrangements and transactions that can give rise to material

off-balance sheet obligations. As of December 31, 2020, the material off-balance sheet arrangements and
transactions that we have entered into include (i) non-operated drilling commitments, (ii) firm gathering,
transportation, processing, fractionation, sales and disposal commitments and (iii) contractual obligations for which
the ultimate settlement amounts are not fixed and determinable, such as derivative contracts that are sensitive 
to future changes in commodity prices or interest rates, gathering, treating, transportation and disposal commitments 
on uncertain volumes of future throughput, open delivery commitments and indemnification obligations following
certain divestitures. Other than the off-balance sheet arrangements described above, the Company has no
transactions, arrangements or other relationships with unconsolidated entities or other persons that are reasonably
likely to materially affect our liquidity or availability of or requirements for capital resources. See “—Obligations 
and Commitments” below and Note 14 to the consolidated financial statements in this Annual Report for more

The amounts included in the table above represent principal maturities only. At December 31, 2020, we had $440.0 million of borrowings
outstanding under the Credit Agreement, approximately $45.8 million in outstanding letters of credit issued pursuant to the Credit Agreement
and $7.5 million in borrowings under the SBA loan. The Credit Agreement matures in October 2023. At December 31, 2020 San Mateo had
$334.0 million of borrowings outstanding under the San Mateo Credit Facility and approximately $9.0 million in outstanding letters of credit
issued pursuant to the San Mateo Credit Facility. The San Mateo Credit Facility matures in December 2023. Assuming the amounts outstanding
and interest rates of 1.90% and 2.15%, for the Credit Agreement and the San Mateo Credit Facility, respectively, at December 31, 2020, the
interest expense for such facilities is expected to be approximately $8.5 million and $7.3 million each year until maturity.

(2) The amounts included in the table above represent principal maturities only. Interest expense on the $1.05 billion of Notes that were outstanding 

as of December 31, 2020 is expected to be approximately $61.7 million each year until maturity.

(3) At December 31, 2020, we had outstanding commitments to drill and complete and to participate in the drilling and completion of various

operated and non-operated wells.

(4) We do not own or operate our own drilling rigs, but instead we enter into contracts with third parties for such drilling rigs. See Note 14 to the 

consolidated financial statements in this Annual Report for more information regarding these contractual commitments.

(5) The amounts included in the table above represent discounted cash flow estimates for future asset retirement obligations at December 31, 2020.

(6) From time to time, we enter into agreements with third parties whereby we commit to deliver anticipated natural gas and oil production and

produced water from certain portions of our acreage for gathering, transportation, processing, fractionation, sales and disposal. Certain of these 
agreements contain minimum volume commitments. If we do not meet the minimum volume commitments under these agreements, we
would be required to pay certain deficiency fees. See Note 14 to the consolidated financial statements in this Annual Report for more information 
about these contractual commitments.

(7) In February 2017, in connection with the formation of San Mateo I, we dedicated our current and certain future leasehold interests in the

Rustler Breaks and Wolf asset areas pursuant to 15-year, fixed-fee oil, natural gas and produced water gathering and produced water disposal
agreements. In addition, effective February 1, 2017, we dedicated our current and certain future leasehold interests in the Rustler Breaks asset
area pursuant to a 15-year, fixed-fee natural gas processing agreement. In February 2019, in connection with the formation of San Mateo II, 
we dedicated acreage in the Greater Stebbins Area and the Stateline asset area pursuant to 15-year, fixed-fee oil, natural gas and produced water
gathering, natural gas processing and produced water disposal agreements. See Note 14 to the consolidated financial statements in this

MATADOR RESOURCES COMPANY 

GENERAL OUTLOOK AND TRENDS

Our business success and financial results are dependent on many factors beyond our control, such as 

economic, political and regulatory developments, as well as competition from other sources of energy. Commodity
price volatility, in particular, is a significant risk to our business and results of operations. Commodity prices are
affected by changes in market supply and demand, which are impacted by overall economic activity, the actions of 
OPEC+, the worldwide spread of COVID-19, weather, pipeline capacity constraints, inventory storage levels, oil 
and natural gas price differentials and other factors.

During the first quarter and through April 2020, the oil and natural gas industry witnessed an abrupt and

significant decline in oil prices from $63 per Bbl in early January to as low as ($38) per Bbl in late April. This sudden
decline in oil prices was attributable to two primary factors: (i) the precipitous decline in global oil demand resulting 
from the worldwide spread of COVID-19 and (ii) a sudden, unexpected increase in global oil supply resulting from 
actions initiated by Saudi Arabia to increase its oil production to world markets following the failure of efforts by 
members of OPEC+ to agree on coordinated production cuts at their March 6, 2020 meetings in Vienna, Austria. 
The sudden decline in oil prices began to improve later in the second quarter of 2020 and throughout the remainder
of 2020 and into early 2021. For the year ended December 31, 2020, oil prices averaged $39.34 per Bbl, ranging 
from a high of $63.27 per Bbl in early January to a low of ($37.63) per Bbl in mid April, based upon the WTI oil
futures contract price for the earliest delivery date.

As noted previously in this Annual Report, we significantly modified our 2020 operational plan primarily as a result 

of these unexpected events and the resulting decline in oil prices. We began 2020 operating six drilling rigs in the
Delaware Basin but reduced our operated drilling program from six to three drilling rigs by the end of the second
quarter of 2020. We operated three drilling rigs in the Delaware Basin throughout the remainder of 2020. We began
2021 operating three drilling rigs in the Delaware Basin as well, but on February 23, 2021, we announced our plans
to add a fourth operated rig in March 2021. We expect to operate four drilling rigs in the Delaware Basin throughout 
the remainder of 2021. While oil prices have continued to improve into 2021, the general outlook for the oil and
natural gas industry for the remainder of the year remains highly uncertain, and we can provide no assurances as to 
when or to what extent the economic disruptions resulting from COVID-19 and the corresponding decline in oil
demand may improve.

We realized a weighted average oil price of $37.38 per Bbl ($39.83 per Bbl including realized gains from
oil derivatives) for our oil production for the year ended December 31, 2020, as compared to $54.34 per Bbl
($54.98 per Bbl including realized gains from oil derivatives) for the year ended December 31, 2019. At 
February 23, 2021, the WTI oil futures contract price for the earliest delivery date had increased from year-end 
2020, closing at $61.67 per Bbl, and was higher compared to $51.43 per Bbl on February 24, 2020. Although 
we have been encouraged by the improved oil price environment in early 2021, we are uncertain that oil prices
can remain at these levels.

Natural gas prices dropped significantly during 2019 and continued to decline during the first half of 2020 before

beginning to increase during the middle of the third quarter and continuing to increase during the fourth quarter.
For the year ended December 31, 2020, natural gas prices averaged $2.13 per MMBtu, as compared to $2.53 per
MMBtu for the year ended December 31, 2019, based upon the NYMEX Henry Hub natural gas futures contract 
price for the earliest delivery date. During 2020, natural gas prices began the year at $2.12 per MMBtu and fell to a
low of $1.48 per MMBtu at the end of June, before increasing to a high of $3.35 per MMBtu in late October and 
finishing the year at $2.54 per MMBtu.

We realized a weighted average natural gas price of $2.14 per Mcf (with no realized gains or losses from natural 

gas derivatives) for our natural gas production for the year ended December 31, 2020, as compared to $2.17 per
Mcf ($2.18 per Mcf including realized gains from natural gas derivatives) for the year ended December 31, 2019. As 
a two-stream reporter, the revenues associated with our NGL production are included in the weighted average 
natural gas price. At February 23, 2021, the NYMEX Henry Hub natural gas futures contract price for the earliest 
delivery date had increased from year-end 2020, closing at $2.88 per MMBtu, and was higher as compared to
$1.83 per MMBtu at February 24, 2020. Although we have been encouraged by the improved natural gas price 
environment, we remain uncertain that natural gas prices can remain at these levels, particularly as we exit the 
winter heating season.

The prices we receive for oil, natural gas and NGLs heavily influence our revenue, profitability, cash flow available

for capital expenditures, access to capital and future rate of growth. Oil, natural gas and NGL prices are subject 
to wide fluctuations in response to relatively minor changes in supply and demand. Historically, the markets for oil, 
natural gas and NGLs have been volatile, and these markets will likely continue to be volatile in the future.
Declines in oil, natural gas or NGL prices not only reduce our revenues, but could also reduce the amount of oil,
natural gas and NGLs we can produce economically, and, as a result, could have an adverse effect on our financial
condition, results of operations, cash flows and reserves and our ability to comply with the leverage ratio covenant
under our Credit Agreement. We are uncertain if oil and natural gas prices may rise from their current levels, and 
in fact, oil and natural gas prices may decrease in future periods. See “Risk Factors—Risks Related to our Financial
Condition—Our success is dependent on the prices of oil and natural gas. Low oil and natural gas prices and
the continued volatility in these prices may adversely affect our financial condition and our ability to meet our capital
expenditure requirements and financial obligations.”

From time to time, we use derivative financial instruments to mitigate our exposure to commodity price risk

associated with oil, natural gas and NGL prices. Even so, decisions as to whether, at what price and what production 
volumes to hedge are difficult and depend on market conditions and our forecast of future production and oil,
natural gas and NGL prices, and we may not always employ the optimal hedging strategy. This, in turn, may affect 
the liquidity that can be accessed through the borrowing base under our Credit Agreement and through the
capital markets.

The prices we receive for oil and natural gas production often reflect a discount to the relevant benchmark prices, 

such as the WTI oil price or the NYMEX Henry Hub natural gas price. The difference between the benchmark
price and the price we receive is called a differential. At December 31, 2020, most of our oil production from the
Delaware Basin was sold based on prices established in Midland, Texas, and most of our natural gas production 
from the Delaware Basin was sold based on Houston Ship Channel pricing, while the remainder of our Delaware
Basin natural gas production was sold primarily based on prices established at the Waha hub in far West Texas.

The Midland-Cushing (Oklahoma) oil price differential has been highly volatile in recent years, but began 2020
slightly positive to the WTI oil price and remained positive through much of the first quarter. With the abrupt decline
in oil prices during the first quarter of 2020, however, the Midland-Cushing (Oklahoma) oil price differential
experienced significant volatility in April 2020, reaching ($6.00) per Bbl before becoming positive later in the second 
quarter and improving throughout the rest of 2020 and into early 2021. It is possible, however, that this differential 
could turn negative again at certain times in the future. At February 23, 2021, we had derivative contracts in place to 
mitigate our exposure to this Midland-Cushing (Oklahoma) oil price differential on a portion of our anticipated oil
production for 2021 and 2022.

   FORM 10-K PART I I

110

MATADOR RESOURCES COMPANY 

A portion of our Delaware Basin natural gas production is exposed to the Waha-Henry Hub basis differential, 
which has also been highly volatile in recent years, including times in April 2019 when natural gas was being sold at 
the Waha hub for negative prices as high as ($7.00) to ($9.00) per MMBtu. In early 2020, the Waha basis differential
remained significant at about ($1.20) per MMBtu and continued to deteriorate. Natural gas prices at the Waha hub 
were negative again on certain days in April 2020. The Waha basis differential narrowed during the remainder of
the second quarter. During the third quarter of 2020 and, in particular, at the beginning of October 2020, the Waha
basis differential widened significantly again, including several days when natural gas was being sold at the
Waha hub for negative prices, due to seasonal pipeline maintenance and other factors that reduced capacity out
of the Waha hub. These capacity issues have been largely resolved and the Waha basis differential improved during
the remainder of 2020 and into early 2021.

The majority of our Delaware Basin natural gas production, however, is sold at Houston Ship Channel pricing 
and is not exposed to Waha pricing. During 2020, we have typically realized a premium to natural gas sold at the 
Waha hub despite higher transportation charges incurred to transport the natural gas to the Gulf Coast. At certain
times, we may also sell a portion of our natural gas production into other markets, e.g., Southern California, to 
improve our realized natural gas pricing. Further, approximately 18% of our reported natural gas production for the
year ended December 31, 2020 was attributable to the Haynesville and Eagle Ford shale plays, which are not 
exposed to Waha pricing. In addition, as a two-stream reporter, most of our natural gas volumes in the Delaware
Basin are processed for NGLs, resulting in a further reduction in the reported natural gas volumes exposed to
Waha pricing.

We anticipate that the volatility in these oil and natural gas price differentials could persist throughout 2021 or 
longer as additional oil and natural gas pipeline capacity from West Texas to the Texas Gulf Coast and other end 
markets is completed and as the balance between oil supply and demand is restored. We can provide no 
assurances as to how long these volatile differentials may persist, and as noted above, these price differentials 
could deteriorate in future periods. Should we experience future periods of negative pricing for natural gas as we
have in previous periods, we may temporarily shut in certain high gas-oil ratio wells and take other actions to
mitigate the impact on our realized natural gas prices and results of operations. In addition, we have no derivative 
contracts in place to mitigate our exposure to natural gas price differentials during 2021 or for future periods.

In addition to concerns regarding oil and natural gas prices and basis differentials, the destruction of global oil 

demand resulting from the decline in economic activity associated with COVID-19, in conjunction with the 
actions initiated by Saudi Arabia in March 2020 to increase its oil production to world markets, led to a significant 
oversupply of oil worldwide. On April 10, 2020, the members of OPEC+ (led by Saudi Arabia) reversed course
and announced their intentions to reduce oil production significantly for the remainder of 2020 and into 2021 and 
2022. The members of OPEC+ have generally adhered to these production cuts, which have contributed to 
improving oil prices, although OPEC+ may decide to eliminate or reduce such production cuts at a future meeting. 
It is uncertain to what degree these production cuts may restore the balance between oil supply and demand, 
and most oil and natural gas industry observers remain skeptical that oil prices can improve further until oil demand
improves, most likely as a result of the “re-opening” of the world economy as concerns surrounding COVID-19 
begin to subside.

During times of low oil prices, we may elect to shut in or curtail certain volumes of our oil production temporarily
rather than sell the oil at further depressed prices. We voluntarily curtailed or shut in portions of our Delaware Basin
and Eagle Ford shale oil production in May and June 2020, but these shut-in wells have since been returned to 
production. As most of our natural gas production in the Delaware Basin is associated with oil production, portions 
of our natural gas production were also curtailed or shut in. Furthermore, our Delaware Basin production in the 
first quarter of 2021 has also been impacted by the historically prolonged cold weather conditions experienced in
New Mexico and Texas during the middle to latter portions of February. During that time, we estimate that 

FORM 10-K PART I I

2020 ANNUAL REPORT

111    

approximately 30% of our average daily oil equivalent production was shut-in, although we continued producing and 
selling the majority of our oil and natural gas during this period. We have experienced minimal impact to our production
volumes due to insufficient storage capacity or damage to refineries downstream of our operations as a result of
this winter weather, but if we were to experience such difficulties, we may be required to shut in additional 
production. When shut-in wells resume production, they may not produce at their previous rates, and we may
be required to expend capital to improve their production. We can provide no assurances as to whether additional 
portions of our production may be shut in or curtailed in the future or how long these periods may persist.

At February 23, 2021, we had not experienced material pipeline-related interruptions to our oil, natural gas 
or NGL production. In certain recent periods, shortages of NGL fractionation capacity were experienced by certain 
operators in the Delaware Basin. Although we did not encounter such fractionation capacity problems, we can
provide no assurances that such problems will not arise. If we do experience any interruptions with takeaway 
capacity or NGL fractionation, our oil and natural gas revenues, business, financial condition, results of operations 
and cash flows could be adversely affected.

Our oil and natural gas exploration, development, production, midstream and related operations are subject to 

extensive federal, state and local laws, rules and regulations. The regulatory burden on the oil and natural gas 
industry increases our cost of doing business and affects our profitability. Because these laws, rules and regulations
are frequently amended or reinterpreted and new laws, rules and regulations are proposed or promulgated, we 
are unable to predict the future cost or impact of complying with the laws, rules and regulations to which we are,
or will become, subject. For example, although such bills have not passed, in recent years, various bills have been 
introduced in the New Mexico legislature proposing to add a surtax on natural gas processors and proposing 
to place a moratorium on, ban or otherwise restrict hydraulic fracturing, including prohibiting the injection of fresh 
water in such operations. In 2019, New Mexico’s governor also signed an executive order requiring a regulatory 
framework to ensure reductions of methane emissions. Following that executive order, the NMOCD, NMED and
New Mexico legislature have proposed various rules, regulations and bills regarding the reduction of natural gas
waste and the control of emissions that would, among other items, require upstream and midstream operators to
reduce natural gas waste by a fixed amount each year and achieve a 98% natural gas capture rate by the end of
2026. These and other laws, rules and regulations, including any federal legislation, regulations or orders intended to
limit or restrict oil and natural gas operations on federal lands, if enacted, could have an adverse impact on our 
business, financial condition, results of operations and cash flows. In January 2021, the Biden administration issued 
the Biden Administration Federal Lease Orders. The pause relating to federal oil and natural gas leases in these 
orders has not restricted activities on existing valid leases. As such, we have continued our operations on federal 
properties. However, we can provide no assurances that federal regulations will not be adopted that limit our ability
to develop our federal properties. Should such actions be taken, they would almost certainly impact our 2021
and future drilling and completion plans and could materially impact our production volumes, revenues, reserves,
cash flows and availability under our Credit Agreement. See “Risk Factors—Risks Related to Laws and Regulations—
Approximately 28% of our leasehold and mineral acres in the Delaware Basin is located on federal lands, which 
are subject to administrative permitting requirements and potential federal legislation, regulation and orders that
may limit or restrict oil and natural gas operations on federal lands.”

In addition, certain segments of the investor community have recently expressed negative sentiment towards 
investing in the oil and natural gas industry, recent equity returns in the sector versus other industry sectors have
led to lower oil and natural gas representation in certain key equity market indices and some investors, including 
certain pension funds, university endowments and family foundations, have stated policies to reduce or eliminate
their investments in the oil and natural gas sector based on social and environmental considerations.

Like other oil and natural gas producing companies, our properties are subject to natural production declines.

By their nature, our oil and natural gas wells will experience rapid initial production declines. We attempt to
overcome these production declines by drilling to develop and identify additional reserves, by exploring for new
sources of reserves and, at times, by acquisitions. During times of severe oil, natural gas and NGL price declines,
however, drilling additional oil or natural gas wells may not be economic, and we may find it necessary to
reduce capital expenditures and curtail drilling operations in order to preserve liquidity. A material reduction in capital
expenditures and drilling activities could materially impact our production volumes, revenues, reserves, cash flows 
and our availability under our Credit Agreement. See “Risk Factors—Risks Related to our Financial Condition—
Our exploration, development, exploitation and midstream projects require substantial capital expenditures that may
exceed our cash flows from operations and potential borrowings, and we may be unable to obtain needed capital 
on satisfactory terms, which could adversely affect our future growth.”

We strive to focus our efforts on increasing oil and natural gas reserves and production while controlling costs at

a level that is appropriate for long-term operations. Our ability to find and develop sufficient quantities of oil and 
natural gas reserves at economical costs is critical to our long-term success. Future finding and development costs 
are subject to changes in the costs of acquiring, drilling and completing our prospects.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions 

that affect the reported amounts of certain assets, liabilities, revenues and expenses during each reporting period. 
We believe that our estimates and assumptions are reasonable and reliable and that the actual results will not differ 
significantly from those reported; however, such estimates and assumptions are subject to a number of risks and
uncertainties, and such risks and uncertainties could cause the actual results to differ materially from our estimates. 
We consider the following to be our most critical accounting policies and estimates involving significant judgment 
or estimates by our management. See Note 2 to the consolidated financial statements in this Annual Report for further 
details on our accounting policies at December 31, 2020.

Oil and Natural Gas Properties

We use the full-cost method of accounting for our investments in oil and natural gas properties. Under this

method of accounting, all costs associated with the acquisition, exploration and development of oil and natural gas 
properties and reserves, including unproved and unevaluated property costs, are capitalized as incurred and
accumulated in a single cost center representing our activities, which are undertaken exclusively in the United 
States. Such costs include lease acquisition costs, geological and geophysical expenditures, lease rentals on
undeveloped properties, costs of drilling both productive and non-productive wells, capitalized interest on qualifying
projects and general and administrative expenses directly related to acquisition, exploration and development 
activities, but do not include any costs related to production, selling or general corporate administrative activities.

Capitalized costs of oil and natural gas properties are amortized using the unit-of-production method based upon

production and estimates of proved reserves quantities. Unproved and unevaluated property costs are excluded
from the amortization base used to determine depletion. Unproved and unevaluated properties are assessed for
possible impairment on a periodic basis based upon changes in operating or economic conditions. This assessment 
includes consideration of the following factors, among others: the assignment of proved reserves, geological and
geophysical evaluations, intent to drill, remaining lease term and drilling activity and results. Upon impairment, 
the costs of the unproved and unevaluated properties are immediately included in the amortization base. Exploratory 
dry holes are included in the amortization base immediately upon the determination that the well is not productive.

FORM 10-K PART I I

2020 ANNUAL REPORT

113    

Sales of oil and natural gas properties are accounted for as adjustments to net capitalized costs with no gain or 

loss recognized, unless such adjustments would significantly alter the relationship between net capitalized costs
and proved reserves of oil and natural gas. All costs related to production activities and maintenance and repairs are 
expensed as incurred. Significant workovers that increase the properties’ reserves are capitalized.

Ceiling Test

The net capitalized costs of oil and natural gas properties are limited to the lower of unamortized costs less 

related deferred income taxes or the cost center “ceiling.” The cost center ceiling is defined as the sum of:

(a) the present value, discounted at 10%, of future net revenues of proved oil and natural gas reserves,

reduced by the estimated costs of developing these reserves, plus

(b) unproved and unevaluated property costs not being amortized, plus

(c) the lower of cost or estimated fair value of unproved and unevaluated properties included in the costs 

being amortized, if any, less

(d) any income tax effects related to the properties involved.

Any excess of our net capitalized costs above the cost center ceiling as described above is charged to 

operations as a full-cost ceiling impairment. The fair value of our derivative instruments is not included in the ceiling
test computation as we do not designate these instruments as hedge instruments for accounting purposes.

The estimated present value of after-tax future net cash flows from proved oil and natural gas reserves is

highly dependent upon the quantities of proved reserves, the estimation of which requires substantial judgment.
The associated commodity prices and the applicable discount rate used in these estimates are in accordance 
with guidelines established by the SEC. Under these guidelines, oil and natural gas reserves are estimated using
then-current operating and economic conditions, with no provision for price and cost escalations in future periods
except by contractual arrangements. Future net revenues are calculated using prices that represent the arithmetic 
averages of the first-day-of-the-month oil and natural gas prices for the previous 12-month period, and a 10% 
discount factor is used to determine the present value of future net revenues.

Because the cost center ceiling calculation is based on the average of historical prices, which may or may not

be representative of future prices, and requires a 10% discount factor, the resulting estimated value may not be
indicative of the fair market value of our properties. Any impairment related to the excess of our net capitalized
costs above the resulting cost center ceiling should not be viewed as an absolute indicator of a reduction in the
ultimate value of the related oil and natural gas reserves.

Derivative Financial Instruments

From time to time, we use derivative financial instruments to mitigate our exposure to commodity price risk
associated with oil, natural gas and NGL prices. These instruments typically consist of put and call options in the 
form of costless (or zero-cost) collars and swap contracts. Costless collars provide us with downside price protection 
through the purchase of a put option that is financed through the sale of a call option. Because the call option 
proceeds are used to offset the cost of the put option, these arrangements are initially “costless” to us. Three-way
costless collars also provide us with downside price protection through the purchase of a put option, but they also
allow us to participate in price upside through the purchase of a call option. The purchase of both the put option and 
call option are financed through the sale of a call option. Because the proceeds from the call option sale are used to 
offset the cost of the purchased put and call options, these arrangements are also initially “costless” to us.

  FORM 10-K PART I I

 
 
114

MATADOR RESOURCES COMPANY 

In the case of a costless collar, the put option and the call option or options have different fixed price

components. In a swap contract, a floating price is exchanged for a fixed price over a specified period, providing 
downside price protection.

Prior to settlement, our derivative financial instruments are recorded on the balance sheet as either an asset or
a liability measured at fair value. We have elected not to apply hedge accounting for our existing derivative financial
instruments, and as a result, we recognize the change in derivative fair value between reporting periods currently in
our consolidated statements of operations. Such changes in fair value are reported under Revenues as “Unrealized 
gain (loss) on derivatives.” Changes in the fair value of these open derivative financial instruments can have a
significant impact on our reported results from period to period but do not impact our cash flows from operations,
liquidity or capital resources. The fair value of our open derivative financial instruments is determined using
industry-standard models that consider various inputs including: (i) quoted forward prices for commodities, (ii) time
value of money and (iii) current market and contractual prices for the underlying instruments, as well as other 
relevant economic measures.

Realized gains and realized losses from the settlement of derivative financial instruments do have a direct
impact on our cash flow from operations and liquidity. The impact of these settlements is also reported under 
Revenues as “Realized gain (loss) on derivatives.”

Revenue Recognition

We enter into contracts with customers to sell our oil and natural gas production. Revenue from these contracts 

is recognized when our performance obligations under these contracts are satisfied, which generally occurs with 
the transfer of control of the oil and natural gas to the purchaser. Control is generally considered transferred when
the following criteria are met: (i) transfer of physical custody, (ii) transfer of title, (iii) transfer of risk of loss and
(iv) relinquishment of any repurchase rights or other similar rights. Given the nature of the products sold, revenue is 
recognized at a point in time based on the amount of consideration we expect to receive in accordance with the
price specified in the contract. Consideration under the oil and natural gas marketing contracts is typically received
from the purchaser one to two months after production.

The majority of our oil marketing contracts transfer physical custody and title at or near the wellhead or a CDP, 
which is generally when control of the oil has been transferred to the purchaser. The majority of the oil produced is
sold under contracts using market-based pricing, which price is then adjusted for differentials based upon delivery 
location and oil quality. To the extent the differentials are incurred at or after the transfer of control of the oil, the 
differentials are included in oil revenues on the statements of operations, as they represent part of the transaction
price of the contract. If the differentials, or other related costs, are incurred prior to the transfer of control of 
the oil, those costs are included in production taxes, transportation and processing expenses on our consolidated 
statements of operations, as they represent payment for services performed outside of the contract with
the customer.

Our natural gas is sold at the lease location, at the inlet or outlet of a natural gas processing plant or at an 

interconnect near a marketing hub following transportation from a processing plant. The majority of our natural gas
is sold under fee-based contracts. When the natural gas is sold at the lease, the purchaser gathers the natural 
gas and transports the natural gas via pipeline to natural gas processing plants where, if necessary, NGLs are 
extracted. The NGLs and remaining residue gas are then sold by the purchaser, or if we elect to take in-kind 
the natural gas or NGLs, we sell the natural gas or NGLs to a third party. Under the fee-based contracts, we receive 
NGL and residue gas value, less the fee component, or are invoiced the fee component. To the extent control
of the natural gas transfers upstream of the transportation and processing activities, revenue is recognized as the 

FORM 10-K PART I I

2020 ANNUAL REPORT

115    

net amount received from the purchaser. To the extent that control transfers downstream of those services, 
revenue is recognized on a gross basis, and the related costs are included in production taxes, transportation and 
processing expenses on our consolidated statements of operations.

We recognize midstream services revenues at the time services have been rendered and the price is fixed and 

determinable. Third-party midstream services revenues are those revenues from midstream operations related
to third parties, including working interest owners in our operated wells. All midstream services revenues related to
our working interest are eliminated in consolidation. Since we have a right to payment from our customers in 
amounts that correspond directly to the value that the customer receives from the performance completed on each 
contract, we apply the practical expedient in Accounting Standards Update 2014-09, Revenue from Contracts 
with Customers (Topic 606) that allows recognition of revenue in the amount for which there is a right to invoice the
customer without estimating a transaction price for each contract and allocating that transaction price to the
performance obligations within each contract.

)

We periodically enter into natural gas purchase transactions with third parties whereby we (i) purchase the third 
party’s natural gas and subsequently sell the natural gas to other purchasers or (ii) process the third party’s natural
gas at the Black River Processing Plant and then purchase, and subsequently sell, the residue gas and NGLs to 
other purchasers. Revenues and expenses from these transactions are presented on a gross basis on our
consolidated statements of operations as we act as a principal in the transactions by assuming the risk and rewards
of ownership, including credit risk, of the natural gas purchased and by assuming the responsibility to deliver and 
process the natural gas volumes to be sold.

From time to time, we, as an owner of mineral interests, may enter into or extend a lease to a third-party lessee

to develop the oil and natural gas attributable to certain of our mineral interests in return for a specified payment
or lease bonus. In those instances, revenue is recognized in the period when the lease is signed, and we have no
further obligation to the lessee. We record these payments as “Lease bonus - mineral acreage” revenues on our 
consolidated statements of operations.

Stock-Based Compensation

We may grant equity-based and liability-based common stock, stock options, restricted stock, restricted stock

units, performance stock units and other awards permitted under any long-term incentive plan then in effect to 
members of our Board of Directors and certain employees, contractors and advisors. We use the fair value method 
to measure and recognize the liability associated with our outstanding liability-based stock options (all of which
were settled in the first quarter of 2020) and to measure and recognize the equity associated with our equity-based 
stock options. Stock options typically vest over three or four years, and the associated compensation expense is
recognized on a straight-line basis over the vesting period. Restricted stock and restricted stock units typically vest
over a period of one to four years, and compensation expense is recognized on a straight line basis over the vesting 
period. We use our own historical volatility to estimate the future volatility of our stock.

We have adopted the “simplified method” as outlined in Staff Accounting Bulletin Topic 14 for estimating the
expected term of awards. The risk free interest rate is the rate for constant yield U.S. Treasury securities with a
term to maturity that is consistent with the expected term of the award.

Assumptions are reviewed each time new equity-based option awards are granted and are reviewed quarterly 

for outstanding liability-based option awards. The assumptions used may be impacted by actual fluctuations in
our stock price, movements in market interest rates and option terms. The use of different assumptions produces a
different fair value for equity-based option awards and outstanding liability-based option awards and can significantly 
impact the amount of stock compensation expense recognized in our consolidated statement of operations or

      FORM 10-K PART I I 

 
 
116

MATADOR RESOURCES COMPANY 

capitalized in accordance with our policy on capitalizing general and administrative expenses for employees involved in
acquisition, exploration and development activities. We use the Black Scholes Merton model to determine the fair 
value of service-based option awards and the Monte Carlo method to determine the fair value of awards that contain
a market condition. The fair value of restricted stock and restricted stock unit awards is recognized based on the
closing price of our common stock on the date of the grant for awards issued under the 2003 Incentive Plan and the
2012 Incentive Plan and on the trading day prior to the date of grant for awards issued under the 2019 Incentive
Plan. See Note 9 to the consolidated financial statements in this Annual Report for further details on our stock-based 
compensation at December 31, 2020.

Income Taxes

We account for income taxes using the asset and liability approach for financial accounting and reporting. The
amount of income taxes recorded requires interpretations of complex rules and regulations of federal and state 
taxing authorities. We have recognized deferred tax assets and liabilities for temporary differences, operating losses 
and tax carryforwards. We evaluate the probability of realizing the future benefits of our deferred tax assets and 
provide a valuation allowance for the portion of any deferred tax assets where the likelihood of realizing an income 
tax benefit in the future does not meet the more likely than not criteria for recognition.

We account for uncertainty in income taxes by recognizing the financial statement benefit of a tax position 
only after determining that the relevant tax authority would more likely than not sustain the position following an
audit. For tax positions meeting the more likely than not threshold, the amount recognized in the financial 
statements is the benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with
the relevant tax authority.

Oil and Natural Gas Reserves Quantities and Standardized Measure of Future Net Revenue

Our engineers and technical staff prepare our estimates of oil and natural gas reserves and associated future

net revenues. While the applicable rules allow us to disclose proved, probable and possible reserves, we have 
elected to present only proved reserves in this Annual Report. The applicable rules define proved reserves as the 
quantities of oil and natural gas, which, by analysis of geoscience and engineering data, can be estimated with 
reasonable certainty to be economically producible—from a given date forward, from known reservoirs and under 
existing economic conditions, operating methods and government regulations—prior to the time at which contracts 
providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of 
whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons 
must have commenced, or the operator must be reasonably certain that it will commence the project within a 
reasonable time.

Our engineers and technical staff must make many subjective assumptions based on their professional judgment

in developing reserves estimates. Reserves estimates are updated quarterly and consider recent production
levels and other technical information about each well. Estimating oil and natural gas reserves is complex and inexact 
because of the numerous uncertainties inherent in the process. The process relies on interpretations of available
geological, geophysical, petrophysical, engineering and production data. The extent, quality and reliability of both the
data and the associated interpretations can vary. The process also requires certain economic assumptions,
including, but not limited to, oil and natural gas prices, development expenditures, operating expenses, capital 
expenditures and taxes. Actual future production, oil and natural gas prices, revenues, taxes, development
expenditures, operating expenses and quantities of recoverable oil and natural gas will most likely vary from our
estimates. Accordingly, reserves estimates are generally different from the quantities of oil and natural gas that are
ultimately recovered. Any significant variance could materially and adversely affect our future reserves estimates, 

FORM 10-K PART I I

2020 ANNUAL REPORT

117

financial condition, results of operations and cash flows. We cannot predict the amounts or timing of future 
reserves revisions. If such revisions are significant, they could significantly affect future amortization of capitalized
costs and result in an impairment of assets that may be material. See “Risk Factors—Risks Related to our Financial
Condition—Our oil and natural gas reserves are estimated and may not reflect the actual volumes of oil and natural
gas we will recover, and significant inaccuracies in these reserves estimates or underlying assumptions will 
materially affect the quantities and present value of our reserves” and “Risk Factors—Risks Related to our Financial 
Condition—We may be required to write down the carrying value of our proved properties under accounting rules,
and these write-downs could adversely affect our financial condition.”

Leases

On January 1, 2019, the Company began recording in the consolidated balance sheet certain of the Company’s

compressor leases, drilling rig leases and office leases, which were previously considered operating leases
and not reported on the Company’s consolidated balance sheets. The present value of the related lease payments
is recorded as a liability and an equal amount is capitalized as a right of use asset on the Company’s consolidated
balance sheet. Right of use assets represent the Company’s right to use an underlying asset for the lease term and 
lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The Company’s
estimated incremental borrowing rate, determined at the lease commencement date using the Company’s average 
secured borrowing rate, is used to calculate present value. For these purposes, the lease term includes options 
to extend the lease when it is reasonably certain that the Company will exercise such option. Leases with terms of
12 months or less at inception are not recorded on the consolidated balance sheet unless there is a significant 
cost to terminate the lease, including the cost of removal of the leased asset. As the Company is the responsible
party under these arrangements, the Company records the resulting assets and liabilities on a gross basis in its 
consolidated balance sheets.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

We are exposed to a variety of market risks including commodity price risk, interest rate risk and counterparty 
and customer risk. We address these risks through a program of risk management including the use of derivative 
financial instruments, but we do not enter into derivative financial instruments for trading purposes.

Commodity price exposure. We are exposed to market risk as the prices of oil, natural gas and NGLs fluctuate
as a result of changes in supply and demand and other factors. To partially reduce price risk caused by these market
fluctuations, we have entered into derivative financial instruments in the past and expect to enter into derivative
financial instruments in the future to cover a significant portion of our anticipated future production.

We typically use costless (or zero-cost) collars, three-way collars and/or swap contracts to manage risks related 

to changes in oil, natural gas and NGL prices. Costless collars provide us with downside price protection through
the purchase of a put option that is financed through the sale of a call option. Because the call option proceeds are 
used to offset the cost of the put option, these arrangements are initially “costless” to us. Three-way costless 
collars also provide us with downside price protection through the purchase of a put option, but they also allow us 
to participate in price upside through the purchase of a call option. The purchase of both the put option and call
option are financed through the sale of a call option. Because the proceeds from the call option sale are 
used to offset the cost of the purchased put and call options, these arrangements are also initially “costless”
to us. In the case of a costless collar, the put option or options and the call option have different fixed price 
components. In a swap contract, a floating price is exchanged for a fixed price over a specified period, providing
downside price protection.

We record all derivative financial instruments at fair value. The fair value of our derivative financial instruments
is determined using purchase and sale information available for similarly traded securities. At December 31, 2020,
The Bank of Nova Scotia, BMO Harris Financing (Bank of Montreal) and Truist Bank (or affiliates thereof) were the
counterparties for all of our derivative instruments. We have considered the credit standing of the counterparties in 
determining the fair value of our derivative financial instruments.

At December 31, 2020, we had entered into various costless collar contracts to mitigate our exposure to 

fluctuations in oil and natural gas prices, each with an established price floor and ceiling. When the settlement price
is below the price floor established by one or more of these collars, we receive from our counterparty an amount 
equal to the difference between the settlement price and the price floor multiplied by the contract oil or natural gas
volume. When the settlement price is above the price ceiling established by one or more of the costless collars,
we pay our counterparty an amount equal to the difference between the settlement price and the price ceiling 
multiplied by the contract oil or natural gas volume.

At December 31, 2020, we had entered into various swap contracts to mitigate our exposure to oil prices,

including price differences between NYMEX WTI Cushing and Argus WTI Midland crude oil. When the settlement 
price is below the fixed price established by one or more of these swaps, we receive from the counterparty an 
amount equal to the difference between the settlement price and the fixed price multiplied by the contract oil 
volume. When the settlement price is above the fixed price established by one or more of these swaps, we pay to
the counterparty an amount equal to the difference between the settlement price and the fixed price multiplied
by the contract oil volume.

See Note 12 to the consolidated financial statements in this Annual Report for a summary of our open derivative

financial instruments at December 31, 2020. Such information is incorporated herein by reference.

Effect of Derivatives Legislation. The Dodd-Frank Act, among other things, established federal oversight and

regulation of certain derivative products, including commodity hedges of the type we use. The Dodd-Frank Act
requires the CFTC and the SEC to promulgate rules and regulations implementing the Dodd-Frank Act. Although the 
CFTC has finalized certain regulations, others remain to be finalized or implemented, and it is not possible at this 
time to predict when, or if, this will be accomplished. Based upon the limited assessments we are able to make
with respect to the Dodd-Frank Act, there is the possibility that the Dodd-Frank Act could have a substantial and
adverse impact on our ability to enter into and maintain these commodity hedges. In particular, the Dodd-Frank Act
could result in the implementation of position limits and additional regulatory requirements on our derivative
arrangements, which could include new margin, reporting and clearing requirements. In addition, this legislation 
could have a substantial impact on our counterparties and may increase the cost of our derivative arrangements in 
the future. See “Risk Factors—Risks Related to Laws and Regulations—The derivatives legislation adopted by 
Congress could have an adverse impact on our ability to hedge risks associated with our business.”

Interest rate risk. We do not and have not used interest rate derivatives to alter interest rate exposure in an
attempt to reduce interest rate expense on existing debt since we borrowed under our Credit Agreement for the
first time in December 2010. At December 31, 2020, we had outstanding borrowings of $440.0 million at an
interest rate of 1.90% per annum under our Credit Agreement, $1.05 billion in Notes outstanding at a coupon rate
of 5.875% per annum and $334.0 million of outstanding borrowings under the San Mateo Credit Facility at an 
interest rate of 2.15% per annum. If we incur additional indebtedness in the future and at higher interest rates, we 
may use interest rate derivatives. Interest rate derivatives would be used solely to modify interest rate exposure
and not to modify the overall leverage of the debt portfolio.

Counterparty and customer credit risk. Joint interest receivables arise from billing entities that own partial
interests in the wells we operate. These entities participate in our wells primarily based on their ownership in leases
on which we wish to drill. We have limited ability to control participation in our wells. We are also subject to credit 
risk due to concentration of our oil and natural gas receivables with several significant customers and San Mateo is 
subject to the credit risk of its customers. The inability or failure of our or San Mateo’s significant customers to meet 
their obligations or their insolvency or liquidation may adversely affect our financial condition, results of operations 
and cash flows. In addition, our derivative arrangements expose us to credit risk in the event of nonperformance by 
our counterparties.

While we do not require our customers to post collateral and we do not have a formal process in place to
evaluate and assess the credit standing of our significant customers for oil and natural gas receivables and the
counterparties on our derivative instruments, we do evaluate the credit standing of such counterparties as 
we deem appropriate under the circumstances. This evaluation requires us to conduct the due diligence necessary 
to determine credit terms and credit limits, which may include (i) reviewing a counterparty’s credit rating, latest 
financial information and, in the case of a customer with which we have receivables, its historical payment record
and the financial ability of its parent company to make payment if the customer cannot and (ii) undertaking the
due diligence necessary to determine credit terms and credit limits. The counterparties on our derivative financial 
instruments in place at February 23, 2021 were The Bank of Nova Scotia, BMO Harris Financing (Bank of Montreal) 
and Truist Bank (or affiliates thereof), which are lenders (or affiliates thereof) under our Credit Agreement, and we
are likely to enter into any future derivative instruments with such banks or other lenders (or affiliates thereof) party
to the Credit Agreement.

Impact of Inflation. Inflation in the United States has been relatively low in recent years and did not have a
material impact on our results of operations for the years ended December 31, 2020, 2019 and 2018. Although the 
impact of inflation has been generally insignificant in recent years, it is still a factor in the U.S. economy and we
tend to specifically experience inflationary pressure on the cost of oilfield services and equipment with increases in 
oil and natural gas prices and with increases in drilling activity in our areas of operations, including the Wolfcamp 
and Bone Spring plays in the Delaware Basin, the Eagle Ford shale play and the Haynesville shale play. See “Risk
Factors—Risks Related to our Operations—The unavailability or high cost of drilling rigs, completion equipment 
and services, supplies and personnel, including hydraulic fracturing equipment and personnel, could adversely affect
our ability to establish and execute exploration and development plans within budget and on a timely basis, which 
could have a material adverse effect on our financial condition, results of operations and cash flows.”

ITEM 9A. CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Annual Report, we evaluated the effectiveness of the design and 
operation of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange
Act) under the supervision and with the participation of our management, including our Chief Executive Officer 
and our Chief Financial Officer. Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer
concluded that the Company’s disclosure controls and procedures were effective as of December 31, 2020 to 
ensure that (i) information required to be disclosed in the reports it files and submits under the Exchange Act is
recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and 
that (ii) information required to be disclosed under the Exchange Act is accumulated and communicated to the 
Company’s management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate to
allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

During the quarter ended December 31, 2020, there were no changes in our internal controls that have materially

affected or are reasonably likely to have a material effect on our internal control over financial reporting.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting

as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act, as amended. Under the supervision and with the
participation of our management, including our Chief Executive Officer and our Chief Financial Officer, we assessed 
the effectiveness of our internal control over financial reporting as of the end of the period covered by this Annual 
Report based on the framework in 2013 “Internal Control — Integrated Framework” issued by the Committee of
Sponsoring Organizations of the Treadway Commission. Based on that assessment, our Chief Executive Officer and 
our Chief Financial Officer concluded that our internal control over financial reporting was effective to provide 
reasonable assurance regarding the reliability of our financial reporting and the preparation of our financial statements 
for external purposes in accordance with U.S. generally accepted accounting principles.

KPMG, our independent registered public accounting firm, has issued an attestation report on our controls over 

financial reporting as of December 31, 2020 as included herein.

Important Considerations

The effectiveness of our disclosure controls and procedures and our internal control over financial reporting is
subject to various inherent limitations, including cost limitations, judgments used in decision making, assumptions
about the likelihood of future events, the soundness of our systems, the possibility of human error and the risk
of fraud. Moreover, projections of any evaluation of effectiveness to future periods are subject to the risk that 
controls may become inadequate because of changes in conditions and the risk that the degree of compliance with 
policies or procedures may deteriorate over time. Because of these limitations, there can be no assurance that
any system of disclosure controls and procedures or internal control over financial reporting will be successful in
preventing all errors or fraud or in making all material information known in a timely manner to the appropriate
levels of management.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors
Matador Resources Company:

Opinion on Internal Control Over Financial Reporting

We have audited Matador Resources Company and subsidiaries’ (the Company) internal control over financial 
reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) 
issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company
maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based
on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring
Organizations of the Treadway Commission.

)

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2020 and 2019, the 
related consolidated statements of operations, changes in shareholders’ equity, and cash flows for each of the 
years in the three-year period ended December 31, 2020, and the related notes (collectively, the consolidated financial 
statements), and our report dated February 26, 2021 expressed an unqualified opinion on those consolidated
financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting

and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying 
Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion
on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm 
registered with the PCAOB and are required to be independent with respect to the Company in accordance with
the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission
and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we 
plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial 
reporting was maintained in all material respects. Our audit of internal control over financial reporting included 
obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness 
exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed 
risk. Our audit also included performing such other procedures as we considered necessary in the circumstances.
We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance

regarding the reliability of financial reporting and the preparation of financial statements for external purposes
in accordance with generally accepted accounting principles. A company’s internal control over financial reporting
includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, 
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable 
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance
with generally accepted accounting principles, and that receipts and expenditures of the company are being made
only in accordance with authorizations of management and directors of the company; and (3) provide reasonable
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s 
assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.

Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may
become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures 
may deteriorate.

Glossary of Oil and Natural Gas Terms

The following is a description of the meanings of some of the oil and natural gas industry terms used in this

Annual Report.

Batch drilling. The process by which multiple horizontal wells are drilled from a single pad. In batch drilling,
the surface holes for each well are drilled first and then the production holes, including the horizontal laterals for 
each well, are drilled.

Bbl. One stock tank barrel, or 42 U.S. gallons liquid volume, used in this Annual Report in reference to crude oil, 

other liquid hydrocarbons or produced water.

Bcf. One billion cubic feet of natural gas.

BOE. Barrels of oil equivalent, determined using the ratio of one Bbl of crude oil, condensate or NGLs to six Mcf

of natural gas.

BOE/d. BOE per day.

Btu or British thermal unit. The quantity of heat required to raise the temperature of one pound of water by one 

degree Fahrenheit.

Central delivery point or CDP. The point on an oil, natural gas or produced water system where such product is
aggregated from one or more gathering or transportation pipelines, wells, tank batteries or leases. Custody is often 
transferred to a third party at a central delivery point.

Completion. The operations required to establish production of oil or natural gas from a wellbore, usually involving 

perforations, stimulation and/or installation of permanent equipment in the well, or in the case of a dry hole, the
reporting of abandonment to the appropriate agency.

Condensate. Liquid hydrocarbons associated with the production of a primarily natural gas reservoir.

Conventional reservoirs or resources. Natural gas or oil that is produced by a well drilled into a geologic formation

in which the reservoir and fluid characteristics permit the natural gas or oil to readily flow to the wellbore.

Coring. The act of taking a core. A core is a solid column of rock, usually from two to four inches in diameter, 

taken as a sample of an underground formation. It is common practice to take cores from wells in the process
of being drilled. A core bit is attached to the end of the drill pipe. The core bit then cuts a column of rock from the 
formation being penetrated. The core is then removed and tested for evidence of oil or natural gas, and its
characteristics (porosity, permeability, etc.) are determined.

Developed acreage. The number of acres that are allocated or assignable to productive wells.

Development well. A well drilled into a proved oil or natural gas reservoir to the depth of a stratigraphic horizon

known to be productive.

Differential. The difference between a particular oil or natural gas price and the applicable benchmark price, such

as the NYMEX West Texas Intermediate oil price or the NYMEX Henry Hub natural gas price.

Dry hole. A well found to be incapable of producing hydrocarbons in sufficient quantities such that proceeds from 

the sale of such production exceed production-related expenses and taxes.

Exploratory well. A well drilled to find and produce oil or natural gas reserves not classified as proved, to find
a new reservoir in a field previously found to be productive of oil or natural gas in another reservoir or to extend a 
known reservoir.

   Glossary of Oil and Natural Gas Terms   FORM 10-K 

134

MATADOR RESOURCES COMPANY 

Farmin or farmout. An agreement under which the owner of a working interest in an oil or natural gas lease 

assigns the working interest or a portion of the working interest to another party who desires to drill on the leased 
acreage. Generally, the assignee is required to drill one or more wells in order to earn its interest in the acreage.
The assignor usually retains a royalty or reversionary interest in the lease. The interest received by an assignee is a 
“farmin” while the interest transferred by the assignor is a “farmout.”

Field. An area consisting of a single reservoir or multiple reservoirs all grouped on or related to the same 

individual geological structural feature and/or stratigraphic condition.

Gross acres or gross wells. The total acres or wells in which a working interest is owned.

Held by production. An oil and natural gas property under lease in which the lease continues to be in force after 

the primary term of the lease in accordance with its terms as a result of production from the property.

Horizontal drilling or well. A drilling operation in which a portion of the well is drilled horizontally within a

productive or potentially productive formation. This operation typically yields a horizontal well that has the ability to 
produce higher volumes than a vertical well drilled in the same formation. A horizontal well is designed to replace 
multiple vertical wells, resulting in lower capital expenditures for draining like acreage and limiting surface disruption.

Hydraulic fracturing. The technique of improving a well’s production or injection rates by pumping a mixture of 
fluids into the formation and rupturing the rock, creating an artificial channel. As part of this technique, sand or other 
material may also be injected into the formation to prop the channel open, so that fluids or gases may more easily 
flow from the formation, through the fracture channel and into the wellbore. This technique may also be referred to
as fracture stimulation.

Lateral length. Length of the completed portion of a horizontal well.

Liquids. Liquids, or natural gas liquids, are marketable liquid products including ethane, propane, butane, pentane

and natural gasoline resulting from the further processing of liquefiable hydrocarbons separated from raw natural
gas by a natural gas processing facility.

MBbl. One thousand barrels of crude oil, other liquid hydrocarbons or produced water.

MBOE. One thousand BOE.

Mcf. One thousand cubic feet of natural gas.

MMBtu. One million British thermal units.

MMcf. One million cubic feet of natural gas.

NGL. Natural gas liquids.

Net acres or net wells. The sum of the fractional working interest owned in gross acres or wells.

Net revenue interest. The interest that defines the percentage of revenue that an owner of a well receives from 

the sale of oil, natural gas and/or natural gas liquids that are produced from the well.

NYMEX. New York Mercantile Exchange.

Organization of Petroleum Exporting Countries or OPEC. An intergovernmental group of 13 of the world’s major
oil-exporting countries, which was founded in 1960 to coordinate the petroleum policies of its members and to 
provide member countries with technical and economic aid.

OPEC+. A loose affiliation of the member countries of OPEC and 10 of the world’s other major oil-exporting

countries, including Russia.

Overriding royalty interest. A fractional interest in the gross production of oil and natural gas under a lease, in

addition to the usual royalties paid to the lessor, free of any expense for exploration, drilling, development, operating, 
marketing and other costs incident to the production and sale of oil and natural gas produced from the lease. It is 
an interest carved out of the lessee’s working interest, as distinguished from the lessor’s reserved royalty interest.

Pad. The surface constructed to accommodate the drilling, completion and production operations of an oil or 

natural gas well.

Pad drilling. The process by which multiple horizontal wells are drilled from a single pad. In pad drilling, each well 

on the pad is drilled to total depth before the next well is initiated.

Permeability. A reference to the ability of oil and/or natural gas to flow through a reservoir.

Petrophysical analysis. The interpretation of well log measurements, obtained from a string of electronic tools
inserted into the borehole, and from core measurements, in which rock samples are retrieved from the subsurface,
then combining these measurements with other relevant geological and geophysical information to describe the
reservoir rock properties.

Play. A set of known or postulated oil and/or natural gas accumulations sharing similar geologic, geographic and
temporal properties, such as source rock, migration pathways, timing, trapping mechanism and hydrocarbon type.

Possible reserves. Additional reserves that are less certain to be recognized than probable reserves.

Probable reserves. Additional reserves that are less certain to be recognized than proved reserves but which, in

sum with proved reserves, are as likely as not to be recovered.

Producing well, or productive well. A well that is found to be capable of producing hydrocarbons in sufficient 
quantities such that proceeds from the sale of the well’s production exceed production-related expenses and taxes.

Properties. Natural gas and oil wells, production and related equipment and facilities and oil, natural gas, or other 

mineral fee, leasehold and related interests.

Prospect. A specific geographic area which, based on supporting geological, geophysical or other data and

preliminary economic analysis using reasonably anticipated prices and costs, is considered to have potential for the 
discovery of commercial hydrocarbons.

Prospectivity. Having the potential for the discovery and/or future development of commercial hydrocarbons in

a specific geographic area or formation.

Proved developed non-producing. Hydrocarbons in a potentially producing horizon penetrated by a wellbore, the 
production of which has been postponed pending installation of surface equipment or gathering facilities, or pending
the production of hydrocarbons from another formation penetrated by the wellbore. The hydrocarbons are
classified as proved developed but non-producing reserves.

Proved developed reserves. Proved reserves that can be expected to be recovered through existing wells and 

facilities and by existing operating methods.

Proved reserves. Reserves of oil and natural gas that have been proved to a high degree of certainty by analysis of

the producing history of a reservoir and/or by volumetric analysis of adequate geological and engineering data.

Proved undeveloped reserves. Proved reserves that are expected to be recovered from new wells on undrilled 

acreage or from existing wells where a relatively major expenditure is required for recompletion.

Recompletion. Completing in the same wellbore to reach a new reservoir after production from the original 

reservoir has been abandoned.

Repeatability. The potential ability to drill multiple wells within a prospect or trend.

136

MATADOR RESOURCES COMPANY 

Reservoir. A porous and permeable underground formation containing a natural accumulation of producible oil 
and/or natural gas that is confined by impermeable rock or water barriers and is individual and separate from other 
reservoirs.

Royalty interest. An interest in an oil and natural gas lease that gives the owner of the interest the right to receive 

a portion of the production from the leased acreage (or of the proceeds of the sale thereof), but generally does not 
require the owner to pay any portion of the costs of drilling or operating the wells on the leased acreage. Royalties
may be either landowner’s royalties, which are reserved by the owner of the leased acreage at the time the
lease is granted, or overriding royalties, which are usually reserved by an owner of the leasehold in connection with 
a transfer to a subsequent owner.

2-D seismic. The method by which a cross-section of the earth’s subsurface is created through the interpretation

of reflection seismic data collected along a single source profile.

3-D seismic. The method by which a three-dimensional image of the earth’s subsurface is created through the
interpretation of reflection seismic data collected over a surface grid. 3-D seismic surveys allow for a more detailed
understanding of the subsurface than do 2-D seismic surveys and contribute significantly to field appraisal, 
exploitation and production.

Spud. The act of beginning to drill an oil or natural gas well.

Throughput. The volume of product transported or passing through a pipeline, plant or other facility.

Trend. A region of oil and/or natural gas production, the geographic limits of which have not been fully defined,
having geological characteristics that have been ascertained through supporting geological, geophysical or other data 
to contain the potential for oil and/or natural gas reserves in a particular formation or series of formations.

Unconventional resource play. A set of known or postulated oil and or natural gas resources or reserves

warranting further exploration which are extracted from (i) low-permeability sandstone and shale formations and
(ii) coalbed methane. These plays require the application of advanced technology to extract the oil and natural
gas resources.

Undeveloped acreage. Lease acreage on which wells have not been drilled or completed to a point that would 
permit the production of commercial quantities of oil and natural gas, regardless of whether such acreage contains 
proved reserves. Undeveloped acreage is usually considered to be all acreage that is not allocated or assignable
to productive wells.

Unproved and unevaluated properties. Properties where no drilling or other actions have been undertaken that 

permit such properties to be classified as proved and to which no proved reserves have been assigned.

Vertical well. A hole drilled vertically into the earth from which oil, natural gas or water flows or is pumped.

Visualization. An exploration technique in which the size and shape of subsurface features are mapped and 

analyzed based upon information derived from well logs, seismic data and other well information.

Volumetric reserve analysis. A technique used to estimate the amount of recoverable oil and natural gas. It 

involves calculating the volume of reservoir rock and adjusting that volume for rock porosity, hydrocarbon saturation, 
formation volume factor and recovery factor.

Walking rig. A drilling rig that is capable of moving from one drilling location to another a short distance away 

using a series of hydraulic “feet” built into the substructure of the rig.

Wellbore. The hole made by a well.

Working interest. The operating interest that gives the owner the right to drill, produce and conduct operating

activities on the property and receive a share of production.

MATADOR RESOURCES COMPANY  

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors
Matador Resources Company:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Matador Resources Company and subsidiaries 

(the Company) as of December 31, 2020 and 2019, the related consolidated statements of operations, changes in
shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2020, and the 
related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements
present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the 
results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2020,
in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2020, based on 
criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring 
Organizations of the Treadway Commission, and our report dated February 26, 2021 expressed an unqualified opinion 
on the effectiveness of the Company’s internal control over financial reporting.

)

Change in Accounting Principle

As discussed in Note 2 to the consolidated financial statements, the Company has changed its method of accounting 

for leases as of January 1, 2019 due to the adoption of Accounting Standards Update 2016-02, Leases (Topic 842), and
related amendments.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is 

to express an opinion on these consolidated financial statements based on our audits. We are a public accounting 
firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with
the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission
and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free
of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the 
risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing 
procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding 
the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting 
principles used and significant estimates made by management, as well as evaluating the overall presentation of the 
consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated

financial statements that was communicated or required to be communicated to the audit committee and that:
(1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our
especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in 
any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating
the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures 
to which it relates.

Impact of estimated proved oil and natural gas reserves related to evaluated oil and natural gas 
properties on depletion expense and the ceiling test calculation

As discussed in Note 2 to the consolidated financial statements, the Company uses the full-cost method of 
accounting for its investments in oil and natural gas properties and amortizes capitalized costs of oil and natural gas
properties using the unit-of-production method based on production and estimates of proved reserves quantities.
The Company is required to perform a ceiling test calculation on a quarterly basis and the applicable ceiling is equal to 
the sum of (1) the present value, discounted at 10%, of future net revenues of proved oil and natural gas reserves, 
reduced by the estimated costs of developing these reserves, plus (2) unproved and unevaluated property costs not
being amortized, plus (3) the lower of cost or estimated fair value of unproved and unevaluated properties included
in the costs being amortized, if any, less (4) any income tax effects related to the properties involved. Any excess of
the Company’s net capitalized costs above the cost center ceiling is charged to operations as a full-cost ceiling 
impairment. Estimates of economically recoverable oil and natural gas reserves depend upon a number of factors and
assumptions, including quantities of oil and natural gas that are ultimately recovered, the timing of the recovery of oil
and natural gas reserves, the operating costs incurred, the amount of future development expenditures, and the price
received for the production. For the year ended December 31, 2020, the Company recorded depletion expense 
of evaluated oil and natural gas properties of $334.8 million and recorded a ceiling test impairment of $684.7 million. 
Additionally, as discussed in Note 3 to the consolidated financial statements, the Company recorded $5.3 billion of 
gross evaluated oil and natural gas properties as of December 31, 2020. The Company’s internal reserves engineers 
prepare an estimate of the proved oil and natural gas reserves, and the Company engages external reserves
engineers to independently evaluate the proved oil and natural gas reserves estimated by the Company.

We identified the assessment of the impact of estimated proved oil and natural gas reserves related to evaluated 

oil and natural gas properties on both depletion expense and the ceiling test calculation as a critical audit matter.
There is a high degree of subjectivity in evaluating the estimate of proved oil and natural gas reserves, as auditor
judgment was required to evaluate the assumptions used by the Company related to forecasted production,
development costs, operating costs, and forecasted oil and natural gas prices inclusive of price differentials.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the 
design and tested the operating effectiveness of certain internal controls over the Company’s depletion and ceiling 
test processes. This included controls related to the development of the assumptions listed above used to estimate
proved reserves used in the respective calculations. We evaluated (1) the professional qualifications of the Company’s
internal reserves engineers as well as the external reserves engineers and external engineering firm, (2) the
knowledge, skill, and ability of the Company’s internal and external reserves engineers, and (3) the relationship of the
external reserves engineers and external engineering firm to the Company. We assessed the methodology used
by the Company to estimate the reserves for consistency with industry and regulatory standards. We also compared 
the pricing assumptions, including price differentials, used in the reserves engineers’ estimate of the proved reserves
to publicly available oil and natural gas pricing data. We evaluated assumptions used in the reserves engineers’
estimate regarding future operating and development costs based on actual results. In addition, we compared the
Company’s historical production forecasts to actual production volumes to assess the Company’s ability to accurately
forecast and we compared the forecasted production assumption used by the Company in the current period
to historical production. We read the findings of the Company’s external reserves engineers in connection with our
evaluation of the Company’s reserves estimates. We analyzed the depletion expense calculation for compliance 
with industry and regulatory standards, and recalculated it. We also analyzed the ceiling test impairment calculation
for compliance with industry and regulatory standards. In addition, we performed an independent calculation of
the ceiling test impairment calculation and compared our results with the Company’s results.

MATADOR RESOURCES COMPANY  

Notes to Consolidated Financial Statements

MATADOR RESOURCES COMPANY AND SUBSIDIARIES
December 31, 2020, 2019 and 2018

NOTE 1 — NATURE OF OPERATIONS

Matador Resources Company, a Texas corporation (“Matador” and, collectively with its subsidiaries, the 

“Company”), is an independent energy company engaged in the exploration, development, production and acquisition 
of oil and natural gas resources in the United States, with an emphasis on oil and natural gas shale and other
unconventional plays. The Company’s current operations are focused primarily on the oil and liquids-rich portion of 
the Wolfcamp and Bone Spring plays in the Delaware Basin in Southeast New Mexico and West Texas. The 
Company also operates in the Eagle Ford shale play in South Texas and the Haynesville shale and Cotton Valley 
plays in Northwest Louisiana. Additionally, the Company conducts midstream operations, primarily through
its midstream joint ventures, San Mateo Midstream, LLC (collectively with its subsidiaries, “San Mateo I”) and 
San Mateo Midstream II, LLC (collectively with its subsidiaries, “San Mateo II” and, together with San Mateo I,
“San Mateo”), in support of the Company’s exploration, development and production operations and provides
natural gas processing, oil transportation services, oil, natural gas and produced water gathering services and produced
water disposal services to third parties. Effective October 1, 2020, San Mateo II merged with and into San Mateo I.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The consolidated financial statements include the accounts of Matador and its wholly-owned and majority-owned 

subsidiaries. These consolidated financial statements have been prepared in accordance with generally accepted
accounting principles in the United States of America (“U.S. GAAP”). Accordingly, the Company consolidates
certain subsidiaries and joint ventures that are less-than-wholly-owned and are not involved in oil and natural gas
exploration, including San Mateo, and the net income and equity attributable to the non-controlling interest
in these subsidiaries have been reported separately as required by Accounting Standards Codification (“ASC”), 
Consolidation (Topic 810). The Company proportionately consolidates joint ventures that are less-than-wholly-owned 
and are involved in oil and natural gas exploration. All intercompany balances and transactions have been 
eliminated in consolidation.

Reclassifications

Certain reclassifications have been made to the prior years’ financial statements to conform to the current
year presentation. These reclassifications had no effect on previously reported results of operations, cash flows or
retained earnings.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates 

and assumptions that affect the amounts reported in the financial statements and accompanying notes. These
estimates and assumptions may also affect disclosure of contingent assets and liabilities at the date of the financial 
statements and the reported amounts of revenues and expenses during the reporting period. The Company’s
consolidated financial statements are based on a number of significant estimates, including oil and natural gas 
revenues, accrued assets and liabilities, stock-based compensation, valuation of derivative instruments, deferred tax
assets and liabilities, purchase price allocations and oil and natural gas reserves. The estimates of oil and natural 
gas reserves quantities and future net cash flows are the basis for the calculations of depletion and impairment of
oil and natural gas properties, as well as estimates of asset retirement obligations and certain tax accruals. The

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES — Continued

Company’s oil and natural gas reserves estimates, which are inherently imprecise and based upon many factors that 
are beyond the Company’s control, including oil and natural gas prices, are prepared by the Company’s engineering
staff in accordance with guidelines established by the Securities and Exchange Commission (“SEC”) and then 
audited for their reasonableness and conformance with SEC guidelines by Netherland, Sewell & Associates, Inc., 
independent reservoir engineers. While the Company believes its estimates are reasonable, changes in facts and 
assumptions or the discovery of new information may result in revised estimates. Actual results could differ from
these estimates.

Change in Accounting Principles

Leases. During the first quarter of 2019, the Company adopted Accounting Standards Update (“ASU”) 2016-02,

)

Leases (Topic 842), which require the

Leases (Topic 842) and the amendments provided for in ASU 2018-11,
recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous
U.S. GAAP using a modified retrospective approach. The modified retrospective approach includes a number of
optional practical expedients that the Company chose to apply. These practical expedients relate to (i) the 
identification and classification of leases that commenced before the effective date, (ii) the treatment of initial direct
costs for leases that commenced before the effective date, (iii) the ability to use hindsight in evaluating lessee
options to extend or terminate a lease or to purchase the underlying asset and (iv) the ability to initially apply the 
new lease standard at the adoption date. During the first quarter of 2019, the Company also adopted ASU 2018-01, 
Leases (Topic 842), which is a land easement practical expedient, and, as a result, the Company began evaluating
land easements that are entered into or modified after December 31, 2018. See Note 4 for additional disclosures 
related to leases.

Restricted Cash

Restricted cash represents a portion of the cash associated with the Company’s less-than-wholly-owned 

subsidiaries, primarily San Mateo. By contractual agreement, the cash in the accounts held by the Company’s
less-than-wholly-owned subsidiaries is not to be commingled with other Company cash and is to be used only to
fund the capital expenditures and operations of these less-than-wholly-owned subsidiaries.

Accounts Receivable

The Company sells its operated oil, natural gas and natural gas liquid (“NGL”) production to various purchasers

(See “—Revenues” below.) In addition, the Company may participate with industry partners in the drilling,
completion and operation of oil and natural gas wells. Substantially all of the Company’s accounts receivable are
due from either purchasers of oil, natural gas and NGLs or participants in oil and natural gas wells for which 
the Company serves as the operator. Accounts receivable are due within 30 to 60 days of the production date and 
30 days of the billing date and are stated at amounts due from purchasers and industry partners. Amounts are 
considered past due if they have been outstanding for 60 days or more. No interest is typically charged on past
due amounts.

The Company reviews its need for an allowance for doubtful accounts on a periodic basis and determines the 
allowance, if any, by considering the length of time past due, previous loss history, future net revenues associated 
with the debtor’s ownership interest in oil and natural gas properties operated by the Company and the debtor’s
ability to pay its obligations, among other things. The Company has no allowance for doubtful accounts related to its 
accounts receivable for any reporting period presented.

MATADOR RESOURCES COMPANY  

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES — Continued

For the year ended December 31, 2020, two significant purchasers accounted for 65% of the Company’s total 

oil, natural gas and NGL revenues: Plains Marketing, L.P. (57%) and Exxon Mobil Corporation (8%). For the year
ended December 31, 2019, two significant purchasers accounted for 67% of the Company’s total oil, natural gas 
and NGL revenues: Plains Marketing, L.P. (53%) and BP America Production Company (14%). For the year ended 
December 31, 2018, four significant purchasers accounted for 60% of the Company’s total oil, natural gas and NGL
revenues: Plains Marketing, L.P. (19%), BP America Production Company (15%), Occidental Energy Marketing, Inc. 
(14%), and Western Refining Crude Oil (12%). If the Company lost one or more of these significant purchasers and 
were unable to sell its production to other purchasers on terms it considers acceptable, it could materially and 
adversely affect the Company’s business, financial condition, results of operations and cash flows. At December 31, 
2020, 2019 and 2018, approximately 35%, 31% and 34%, respectively, of the Company’s accounts receivable,
including joint interest billings, related to these purchasers.

Lease and Well Equipment Inventory

Lease and well equipment inventory is stated at the lower of cost or market and consists entirely of materials or 

equipment scheduled for use in future well or midstream operations.

Oil and Natural Gas Properties

The Company uses the full-cost method of accounting for its investments in oil and natural gas properties.
Under this method, all costs associated with the acquisition, exploration and development of oil and natural gas 
properties and reserves, including unproved and unevaluated property costs, are capitalized as incurred and
accumulated in a single cost center representing the Company’s activities, which are undertaken exclusively in the 
United States. Such costs include lease acquisition costs, geological and geophysical expenditures, lease rentals 
on undeveloped properties, costs of drilling both productive and non-productive wells, capitalized interest on qualifying 
projects and general and administrative expenses directly related to acquisition, exploration and development 
activities, but do not include any costs related to production, selling or general corporate administrative activities. 
The Company capitalized $30.0 million, $31.1 million and $28.3 million of its general and administrative costs into oil 
and natural gas properties in 2020, 2019 and 2018, respectively. The Company capitalized $5.0 million, $7.6 million 
and $8.8 million of its interest expense into oil and natural gas properties for the years ended December 31, 2020, 
2019 and 2018, respectively.

Capitalized costs of oil and natural gas properties are amortized using the unit-of-production method based upon 

production and estimates of proved reserves quantities. For the years ended December 31, 2020, 2019 and 2018,
the Company recorded depletion expense of $334.8 million, $330.7 million and $251.8 million, respectively. Unproved
and unevaluated property costs are excluded from the amortization base used to determine depletion.
Unproved and unevaluated properties are assessed for possible impairment on a periodic basis based upon changes
in operating or economic conditions. This assessment includes consideration of the following factors, among 
others: the assignment of proved reserves, geological and geophysical evaluations, intent to drill, remaining lease
term and drilling activity and results. Upon impairment, the costs of the unproved and unevaluated properties
are immediately included in the amortization base. Exploratory dry holes are included in the amortization base
immediately upon determination that the well is not productive.

Sales of oil and natural gas properties are accounted for as adjustments to net capitalized costs with no gain or 

loss recognized, unless such adjustments would significantly alter the relationship between net capitalized costs 
and proved reserves of oil and natural gas. All costs related to production activities and maintenance and repairs are 
expensed as incurred. Significant workovers that increase the properties’ reserves are capitalized.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES — Continued

Ceiling Test

The net capitalized costs of oil and natural gas properties are limited to the lower of unamortized costs less 

related deferred income taxes or the cost center “ceiling.” The cost center ceiling is defined as the sum of:

(a)  the present value, discounted at 10%, of future net revenues of proved oil and natural gas reserves,  

reduced by the estimated costs of developing these reserves, plus

(b)   unproved and unevaluated property costs not being amortized, plus

(c)   the lower of cost or estimated fair value of unproved and unevaluated properties included in the costs  

being amortized, if any, less

(d) any income tax effects related to the properties involved.

Any excess of the Company’s net capitalized costs above the cost center ceiling as described above is 

charged to operations as a full-cost ceiling impairment. The Company’s derivative instruments are not considered
in the ceiling test computations as the Company does not designate these instruments as hedge instruments for
accounting purposes.

The estimated present value of after-tax future net cash flows from proved oil and natural gas reserves is 
highly dependent upon the quantities of proved reserves, the estimation of which requires substantial judgment. 
The associated commodity prices and the applicable discount rate used in these estimates are in accordance 
with guidelines established by the SEC. Under these guidelines, oil and natural gas reserves are estimated using 
then-current operating and economic conditions, with no provision for price and cost changes in future periods 
except by contractual arrangements. Future net revenues are calculated using prices that represent the arithmetic 
averages of the first-day-of-the-month oil and natural gas prices for the previous 12-month period, and a 10% 
discount factor is used to determine the present value of future net revenues. For the period from January through
December 2020, these average oil and natural gas prices were $36.04 per Bbl and $1.99 per MMBtu, respectively. 
For the period from January through December 2019, these average oil and natural gas prices were $52.19 per Bbl
and $2.58 per MMBtu, respectively. For the period from January through December 2018, these average oil and 
natural gas prices were $62.04 per Bbl and $3.10 per MMBtu, respectively. In estimating the present value of after-tax 
future net cash flows from proved oil and natural gas reserves, the average oil prices were further adjusted 
by property for quality, transportation and marketing fees and regional price differentials, and the average natural
gas prices were further adjusted by property for energy content, transportation and marketing fees and regional 
price differentials.

For the year ended December 31, 2020, the Company’s net capitalized costs less related deferred income taxes
exceeded the full-cost ceiling. As a result, the Company recorded an impairment charge of $684.7 million, exclusive
of tax effect, to its consolidated statement of operations for the year ended December 31, 2020 with the related 
deferred income tax benefit recorded net of a valuation allowance (see Note 8).

During the years ended December 31, 2019 and 2018, the Company’s full-cost ceiling exceeded the net
capitalized costs less related deferred income taxes. As a result, the Company recorded no impairment to its 
net capitalized costs during the years ended December 31, 2019 and 2018.

As a non-cash item, the full-cost ceiling impairment impacts the accumulated depletion and the net carrying 
value of the Company’s assets on its consolidated balance sheets, as well as the corresponding shareholders’ 
equity, but it has no impact on the Company’s net cash flows as reported. Changes in oil and natural gas production
rates, oil and natural gas prices, reserves estimates, future development costs and other factors will determine 
the Company’s actual ceiling test computation and impairment analyses in future periods.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES — Continued

Midstream Properties and Other Property and Equipment

Midstream properties and other property and equipment are recorded at historical cost and include midstream 

equipment and facilities, including the Company’s pipelines, processing facilities and produced water disposal 
systems, and corporate assets, including furniture, fixtures, equipment, land and leasehold improvements. 
Midstream equipment and facilities are depreciated over a 30-year useful life using the straight-line, mid-month
convention method. Leasehold improvements are depreciated over the lesser of their useful lives or the term
of the lease. Software, furniture, fixtures and other equipment are depreciated over their useful life (five to 30 years)
using the straight-line method. The Company capitalized $1.8 million, $1.8 million and $1.6 million of general
and administrative costs into midstream properties in 2020, 2019 and 2018, respectively. The Company capitalized 
$0.5 million and $0.9 million of interest expense into midstream properties for the years ended December 31, 2020 
and 2019. The Company did not capitalize any interest expense into midstream properties for the year ended
December 31, 2018. Maintenance and repair costs that do not extend the useful life of the property or equipment 
are expensed as incurred. See Note 3 for a detail of midstream properties and other property and equipment.

The Company evaluates midstream properties and other property and equipment for potential impairment 

whenever events or changes in circumstances indicate that their carrying value may not be recoverable. The 
carrying amount of a long-lived asset is not recoverable when it exceeds the undiscounted sum of the future cash 
flows expected to result from the use and eventual disposition of the asset. Expected future cash flows
represent management’s estimates based on reasonable and supportable assumptions.

Gains and losses associated with the disposition of midstream properties and other property and equipment are 

recognized as a component of other income (expense) in the consolidated statements of operations.

Asset Retirement Obligations

The Company recognizes the fair value of an asset retirement obligation in the period in which it is incurred 
if a reasonable estimate of fair value can be made. The asset retirement obligation is recorded as a liability at its
estimated present value, with an offsetting increase recognized in oil and natural gas properties, midstream
properties or other property and equipment on the consolidated balance sheets. Periodic accretion of the discounted 
value of the estimated liability is recorded as an expense in the consolidated statements of operations.

Derivative Financial Instruments

From time to time, the Company uses derivative financial instruments to mitigate its exposure to commodity

price risk associated with oil, natural gas and NGL prices. The Company’s derivative financial instruments are 
recorded on the consolidated balance sheets as either an asset or a liability measured at fair value. The Company
has elected not to apply hedge accounting for its existing derivative financial instruments, and as a result, the 
Company recognizes the change in derivative fair value between reporting periods currently in its consolidated
statements of operations. The fair value of the Company’s derivative financial instruments is determined using 
industry-standard models that consider various inputs including: (i) quoted forward prices for commodities, (ii) time 
value of money and (iii) current market and contractual prices for the underlying instruments, as well as other 
relevant economic measures. Realized gains and losses from the settlement of derivative financial instruments and
unrealized gains and unrealized losses from valuation changes in the remaining unsettled derivative financial 
instruments are reported as a component of revenues in the consolidated statements of operations. See Note 12 
for additional information about the Company’s derivative instruments.

F-13    

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES — Continued

Revenues

The Company enters into contracts with customers to sell its oil and natural gas production. Revenue from
these contracts is recognized when the Company’s performance obligations under these contracts are satisfied, 
which generally occurs with the transfer of control of the oil and natural gas to the purchaser. Control is generally
considered transferred when the following criteria are met: (i) transfer of physical custody, (ii) transfer of title,
(iii) transfer of risk of loss and (iv) relinquishment of any repurchase rights or other similar rights. Given the nature
of the products sold, revenue is recognized at a point in time based on the amount of consideration the Company 
expects to receive in accordance with the price specified in the contract. Consideration under oil and natural gas
marketing contracts is typically received from the purchaser one to two months after production.

The majority of the Company’s oil marketing contracts transfer physical custody and title at or near the wellhead

or a central delivery point, which is generally when control of the oil has been transferred to the purchaser. The 
majority of the oil produced is sold under contracts using market-based pricing, which price is then adjusted for
differentials based upon delivery location and oil quality. To the extent the differentials are incurred at or after 
the transfer of control of the oil, the differentials are included in oil revenues on the statements of operations, as
they represent part of the transaction price of the contract. If the differentials, or other related costs, are incurred 
prior to the transfer of control of the oil, those costs are included in production taxes, transportation and processing 
expenses on the Company’s consolidated statements of operations, as they represent payment for services
performed outside of the contract with the customer.

The Company’s natural gas is sold at the lease location, at the inlet or outlet of a natural gas processing plant or

at an interconnect near a marketing hub following transportation from a processing plant. The majority of the 
Company’s natural gas is sold under fee-based contracts. When the natural gas is sold at the lease, the purchaser 
gathers the natural gas via pipeline to natural gas processing plants where, if necessary, NGLs are extracted. The
NGLs and remaining residue gas are then sold by the purchaser, or if the Company elects to take in-kind the natural 
gas or the NGLs, the Company sells the natural gas or the NGLs to a third party. Under the fee-based contracts,
the Company receives NGL and residue gas value, less the fee component, or is invoiced the fee component. To the
extent control of the natural gas transfers upstream of the gathering and processing activities, revenue is recognized
as the net amount received from the purchaser. To the extent that control transfers downstream of those services,
revenue is recognized on a gross basis, and the related costs are included in production taxes, transportation and
processing expenses on the Company’s consolidated statements of operations.

The Company recognizes midstream services revenues at the time services have been rendered and the price is

fixed and determinable. Third-party midstream services revenues are those revenues from midstream operations 
related to third parties, including working interest owners in the Company’s operated wells. All midstream services
revenues related to the Company’s working interest are eliminated in consolidation. Since the Company has a right 
to payment from its customers in amounts that correspond directly to the value that the customer receives from the 
performance completed on each contract, the Company applies the practical expedient in Accounting Standards
Update 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASC 606”) that allows recognition of
revenue in the amount for which there is a right to invoice the customer without estimating a transaction price for
each contract and allocating that transaction price to the performance obligations within each contract.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES — Continued

The Company periodically enters into natural gas purchase transactions with third parties whereby the Company
(i) purchases the third party’s natural gas and subsequently sells the natural gas to other purchasers or (ii) processes
the third party’s natural gas at San Mateo’s Black River cryogenic natural gas processing plant in Eddy County,
New Mexico (the “Black River Processing Plant”) and then purchases, and subsequently sells, the residue gas and
NGLs to other purchasers. Revenues and expenses from these transactions are presented on a gross basis on the 
Company’s consolidated statements of operations as the Company acts as a principal in the transactions by
assuming the risk and rewards of ownership, including credit risk, of the natural gas purchased and by assuming
the responsibility to deliver and process the natural gas volumes to be sold.

From time to time, the Company, as an owner of mineral interests, may enter into or extend a lease to a third-
party lessee to develop the oil and natural gas attributable to certain of its mineral interests in return for a specified
payment or lease bonus. In those instances, revenue is recognized in the period when the lease is signed and the
Company has no further obligation to the lessee. The Company records these payments as “Lease bonus - mineral
acreage” revenues on its consolidated statements of operations.

The following table summarizes the Company’s total revenues and revenues from contracts with customers on

a disaggregated basis for the years ended December 31, 2020, 2019 and 2018 (in thousands).

The Company does not disclose the value of unsatisfied performance obligations under its contracts with
customers as it applies the practical expedient in accordance with ASC 606. The expedient, as described in ASC 
606-10-50-14(a), applies to variable consideration that is recognized as control of the product is transferred to the 
customer. Since each unit of product represents a separate performance obligation, future volumes are wholly 
unsatisfied and disclosure of the transaction price allocated to remaining performance obligations is not required.

Stock-Based Compensation

The Company may grant equity-based and liability-based common stock, stock options, restricted stock,

restricted stock units, performance stock units and other awards permitted under any long-term incentive plan of
the Company then in effect to members of its Board of Directors and certain employees, contractors and advisors.
All equity-based awards are measured at fair value on the date of grant and are recognized on a straight-line basis
over the awards’ vesting periods as either a component of general and administrative expenses in the consolidated

statements of operations or capitalized in accordance with the Company’s policy on capitalizing general and 
administrative expenses for employees involved in acquisition, exploration and development activities. Awards that 
are expected to be settled in cash are liability-based awards, which are measured at fair value at each reporting date 
and are recognized over the awards’ vesting periods either as a component of general and administrative expenses 
in the consolidated statements of operations or capitalized in accordance with the Company’s policy on capitalizing
general and administrative expenses for employees involved in acquisition, exploration and development activities.

The Company uses the Black Scholes Merton option pricing model to measure the fair value of stock options and 

the Monte Carlo simulation method to measure the fair value of performance units. The closing price of Matador’s 
common stock on the grant date is used to measure the fair value of restricted stock and restricted stock unit
awards granted under the Company’s 2003 Stock and Incentive Plan (the “2003 Incentive Plan”) and the 2012 
Long-Term Incentive Plan (as subsequently amended and restated, the “2012 Incentive Plan”), while the closing
price of Matador’s common stock on the trading day prior to the grant date is used to measure the fair value 
of restricted stock and restricted stock unit awards granted under the 2019 Long-Term Incentive Plan (the “2019 
Incentive Plan”).

The Company’s consolidated statements of operations for the years ended December 31, 2020, 2019 and 2018 

include a stock-based compensation (non-cash) expense of $13.6 million, $18.5 million and $17.2 million, 
respectively. This stock-based compensation expense includes common stock issuances and restricted stock units 
expense totaling $1.0 million, $1.4 million and $1.6 million for the years ended December 31, 2020, 2019 and 
2018, respectively, paid to independent members of the Board of Directors and advisors as compensation for their
services to the Company. The Company’s consolidated statement of operations for the years ended December 31,
2020 and 2019 also includes $4.0 million and $3.2 million, respectively, related to liability-based awards expected to
be settled in cash.

Income Taxes

The Company accounts for income taxes using the asset and liability approach for financial accounting and 

reporting. The Company evaluates the probability of realizing the future benefits of its deferred tax assets
and records a valuation allowance for the portion of any deferred tax assets when it is more likely than not that the 
benefit from the deferred tax asset will not be realized.

The Company recognizes the tax benefit of an uncertain tax position only if it is more likely than not that the tax

position will be sustained upon examination by the taxing authorities based on the technical merits of the position. 
For tax positions meeting the more likely than not threshold, the amount recognized in the financial statements is 
the benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant 
tax authority. At December 31, 2020, 2019 and 2018, the Company had not established any reserves for, nor recorded 
any unrecognized tax benefits related to, uncertain tax positions.

When necessary, the Company would include interest assessed by taxing authorities in “Interest expense”

and penalties related to income taxes in “Other expense” on its consolidated statements of operations. 
The Company did not record any interest or penalties related to income taxes for the years ended December 31,
2020, 2019 and 2018.

Allocation of Purchase Price in Business Combinations

As part of the Company’s business strategy, it periodically pursues the acquisition of oil and natural gas 

properties. The purchase price in a business combination is allocated to the assets acquired and liabilities assumed 
based on their fair values as of the acquisition date, which may occur many months after the announcement date. 
Therefore, while the consideration to be paid may be fixed, the fair value of the assets acquired and liabilities 
assumed is subject to change during the period between the announcement date and the acquisition date. The 
most significant estimates in the allocation typically relate to the value assigned to proved oil and natural gas
reserves and unproved and unevaluated properties. As the allocation of the purchase price is subject to significant
estimates and subjective judgments, the accuracy of this assessment is inherently uncertain.

Earnings Per Common Share

The Company reports basic earnings attributable to Matador Resources Company shareholders per common 

share, which excludes the effect of potentially dilutive securities, and diluted earnings attributable to Matador
Resources Company shareholders per common share, which includes the effect of all potentially dilutive securities,
unless their impact is anti-dilutive.

The following are reconciliations of the numerators and denominators used to compute the Company’s basic
and diluted earnings per common share as reported for the years ended December 31, 2020, 2019 and 2018 (in 
thousands, except per share data).

Credit Risk

The Company’s cash is held in financial institutions and at times these amounts exceed the insurance limits of
the Federal Deposit Insurance Corporation. Management believes, however, that the Company’s counterparty risks 
are minimal based on the reputation and history of the institutions selected.

The Company uses derivative financial instruments to mitigate its exposure to oil, natural gas and NGL price

volatility. These transactions expose the Company to potential credit risk from its counterparties. The Company
manages counterparty credit risk through established internal derivatives policies that are reviewed on an ongoing
basis. Additionally, all of the Company’s commodity derivative contracts at December 31, 2020 were with The 
Bank of Nova Scotia, BMO Harris Financing, Inc. (Bank of Montreal) and Truist Bank (or affiliates thereof), parties
that are lenders (or affiliates thereof) under the Company’s reserves-based revolving credit agreement.

Accounts receivable constitute the principal component of additional credit risk to which the Company may
be exposed. The Company attempts to minimize credit risk exposure to counterparties by monitoring the financial 
condition and payment history of its purchasers and joint interest partners.

Property acquisition costs primarily include leasehold costs paid to secure oil and natural gas mineral leases, 
but may also include broker and legal expenses, geological and geophysical expenses and capitalized internal costs 
associated with developing oil and natural gas prospects on these properties. Property acquisition costs are
transferred into the amortization base on an ongoing basis as these properties are evaluated and proved reserves
are established or impairment is determined. Unproved and unevaluated properties are assessed for possible
impairment on a periodic basis based upon changes in operating or economic conditions.

Property acquisition costs incurred that remain in unproved and unevaluated property at December 31, 2020 are 

related to the Company’s leasehold and mineral acquisitions in the Delaware Basin in Southeast New Mexico and 
West Texas. These costs are associated with acreage for which proved reserves have yet to be assigned. A
significant portion of these costs are associated with properties that are held by production or have automatic lease
renewal options. As the Company drills wells and assigns proved reserves to these properties or determines that 
certain portions of this acreage, if any, cannot be assigned proved reserves, portions of these costs are transferred 
to the amortization base.

On September 12, 2018, the Company announced the successful acquisition of 8,400 gross and net leasehold

acres in Lea and Eddy Counties, New Mexico for approximately $387 million in the Bureau of Land Management 
New Mexico Oil and Gas Lease Sale on September 5 and 6, 2018 (the “BLM Acquisition”). The BLM Acquisition
was responsible for a significant portion of the Company’s property acquisition costs in 2018.

Costs excluded from amortization also include those costs associated with exploration and development wells 
in progress or awaiting completion at year-end. These costs are transferred into the amortization base on an ongoing
basis as these wells are completed and proved reserves are established or confirmed. These costs totaled 
$33.3 million at December 31, 2020. Of this total, $3.0 million was associated with exploration wells and $30.3 million
was associated with development wells. The Company anticipates that most of the $33.3 million associated with
these wells in progress at December 31, 2020 will be transferred to the amortization base during 2021. Unproved 
and unevaluated property costs for exploration and development wells incurred from 2016 through 2019 are costs
related to the advanced preparation for wells that we intend to drill in the future.

NOTE 4 — LEASES

The Company determines if an arrangement is a lease at inception of the contract. If an arrangement is a lease, 

the present value of the related lease payments is recorded as a liability, and an equal amount is capitalized as
a right of use asset on the Company’s consolidated balance sheets. The Company elected to include payments for 
non-lease components associated with certain leases when determining the present value of the lease payments. 
Right of use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities
represent the Company’s obligation to make lease payments arising from the lease. The Company’s estimated
incremental borrowing rate, determined at the lease commencement date using the Company’s average secured 
borrowing rate, is used to calculate present value. The weighted average estimated incremental borrowing rates 
used for the year ended December 31, 2020 were 3.09% and 2.97% for operating leases and financing leases,
respectively. For these purposes, the lease term includes options to extend the lease when it is reasonably certain
that the Company will exercise such option. Leases with terms of 12 months or less at inception are not recorded
on the consolidated balance sheets unless there is a significant cost to terminate the lease, including the cost of 
removal of the leased asset. As the Company is the responsible party under these arrangements, the Company
records the resulting assets and liabilities on a gross basis in its consolidated balance sheets.

The following table presents supplemental consolidated statement of operations information related to lease
expenses, on a gross basis, for the years ended December 31, 2020 and 2019, respectively (in thousands). Lease
payments represent gross payments to vendors, which, for certain of our operating assets, are partially offset by
amounts received from other working interest owners in our operated wells.

NOTE 5 — ASSET RETIREMENT OBLIGATIONS

The Company’s asset retirement obligations primarily relate to future costs associated with plugging and

abandonment of its oil, natural gas and salt water disposal wells, removal of pipelines, equipment and facilities from 
leased acreage and returning such land to its original condition. The amounts recognized are based on numerous 
estimates and assumptions, including future retirement costs, future recoverable quantities of oil and natural gas,
future inflation rates and the Company’s credit-adjusted risk-free interest rate. Revisions to the liability can occur 
due to changes in these estimates and assumptions or if federal or state regulators enact new plugging and
abandonment requirements. At the time of the actual plugging and abandonment of its oil and natural gas wells, the 
Company includes any gain or loss associated with the operation in the amortization base to the extent the actual
costs are different from the estimated liability.

The following table summarizes the changes in the Company’s asset retirement obligations for the years ended 

December 31, 2020 and 2019 (in thousands).

MATADOR RESOURCES COMPANY  

 NOTE 6 — BUSINESS COMBINATIONS AND DIVESTITURES

Joint Ventures

On February 17, 2017, the Company contributed substantially all of its midstream assets located in the

Rustler Breaks (Eddy County, New Mexico) and Wolf (Loving County, Texas) asset areas in the Delaware Basin to
San Mateo I, a joint venture with a subsidiary of Five Point Energy LLC (“Five Point”). The midstream assets 
contributed to San Mateo I include (i) the Black River Processing Plant (before its expansions); (ii) one salt water
disposal well and a related commercial salt water disposal facility in the Rustler Breaks asset area; (iii) three salt 
water disposal wells and related commercial salt water disposal facilities in the Wolf asset area; and (iv) substantially 
all related oil, natural gas and produced water gathering systems and pipelines in both the Rustler Breaks and 
Wolf asset areas (collectively, the “Delaware Midstream Assets”). The Company continues to operate the Delaware
Midstream Assets and San Mateo I’s other assets. The Company retained its ownership in certain midstream
assets owned in South Texas and Northwest Louisiana, which are not part of San Mateo.

The Company and Five Point own 51% and 49% of San Mateo I, respectively. Five Point provided initial cash 

consideration of $176.4 million to San Mateo I in exchange for its 49% interest. Approximately $171.5 million 
of this cash contribution by Five Point was distributed by San Mateo I to the Company as a special distribution. The 
Company had the potential to earn up to $73.5 million in performance incentives over a five-year period, which in 
October 2020 was extended by an additional year. At February 23, 2021, the Company had earned $58.8 million of
the potential $73.5 million in performance incentives. Through February 23, 2021, Five Point had paid $14.7 million
in performance incentives in each of the first quarters of 2018, 2019 and 2020, and the Company expects Five Point to 
pay an additional $14.7 million in performance incentives in the first quarter of 2021. The Company may earn up to the
remaining $14.7 million in performance incentives over the next two years. These performance incentives are
recorded as additional contributions related to the formation of San Mateo I as they are received. The Company
contributed the Delaware Midstream Assets and $5.1 million in cash to San Mateo I in exchange for its 51% interest.

The Company dedicated its current and certain future leasehold interests in the Rustler Breaks and Wolf asset

areas to San Mateo I pursuant to 15-year, fixed-fee oil, natural gas and produced water gathering and produced
water disposal agreements, effective as of February 1, 2017. In addition, the Company dedicated its current and 
certain future leasehold interests in the Rustler Breaks asset area to San Mateo I pursuant to a 15-year, fixed-fee
natural gas processing agreement (see Note 14).

On February 25, 2019, the Company announced the formation of San Mateo II, a strategic joint venture with 
Five Point designed to expand the Company’s midstream operations in the Delaware Basin, specifically in Eddy County, 
New Mexico. San Mateo II was owned 51% by the Company and 49% by Five Point. In addition, Five Point 
committed to pay $125.0 million of the first $150.0 million of capital expenditures incurred by San Mateo II to 
develop facilities in the Stebbins area and surrounding leaseholds in the southern portion of the Arrowhead asset
area (the “Greater Stebbins Area”) and the Stateline asset area. During the year ended December 31, 2020, the
$150.0 million threshold for capital expenditures was reached, and additional capital expenditures were the 
responsibility of Matador and Five Point based on each company’s proportionate interest. During the year ended
December 31, 2020, the Company contributed $59.7 million and Five Point contributed $105.0 million of cash 
to San Mateo II, of which $23.1 million was paid to carry Matador’s proportionate interest. The portion of the 
amount contributed by Five Point to carry Matador’s proportionate interest was recorded in “Additional paid-in 
capital” in the Company’s consolidated balance sheets at December 31, 2020, net of the $4.8 million deferred tax
impact to Matador related to this equity contribution. During the year ended December 31, 2019, the Company 

FORM 10-K   Notes to Consolidated Financial Statements

2020 ANNUAL REPORT

F-23    

 NOTE 6 — BUSINESS COMBINATIONS AND DIVESTITURES — Continued

contributed $15.5 million of cash, and Five Point contributed $69.0 million of cash, of which $28.4 million was paid 
to carry Matador’s proportionate interest in San Mateo II and was therefore recorded in “Additional paid-in capital” 
in the consolidated balance sheet, net of the $5.9 million deferred tax impact to Matador related to this equity 
contribution. Upon formation of San Mateo II, in the first quarter of 2019, the Company also contributed $1.0 million
of property to San Mateo II. In addition, the Company has the ability to earn up to $150.0 million in deferred
performance incentives over the next several years, plus additional performance incentives for securing volumes
from third-party customers.

In connection with the formation of San Mateo II, the Company dedicated to San Mateo II acreage in the

Greater Stebbins Area and the Stateline asset area pursuant to 15-year, fixed-fee oil, natural gas and produced water 
gathering, natural gas processing and produced water disposal agreements (see Note 14).

Effective October 1, 2020, San Mateo II merged with and into San Mateo I. San Mateo is consolidated
in the Company’s financial statements with Five Point’s interest in San Mateo being accounted for as a non-
controlling interest.

Divestitures

During 2020 and 2019, we converted approximately $4.8 million and $21.9 million, respectively, of non-core 
assets to cash. These properties were primarily located in South Texas and Northwest Louisiana and East Texas but
included a small portion of our leasehold in a non-operated area of the Delaware Basin.

NOTE 7 — DEBT

At December 31, 2020, the Company had (i) $1.05 billion of outstanding senior notes due 2026, (ii) $440.0 million 

in borrowings outstanding under its reserves-based revolving credit facility, (iii) approximately $45.8 million in 
outstanding letters of credit issued pursuant to its revolving credit facility and (iv) $7.5 million outstanding under an 
unsecured U.S. Small Business Administration loan.

At December 31, 2020, San Mateo had $334.0 million in borrowings outstanding under its revolving credit facility

and approximately $9.0 million in outstanding letters of credit issued pursuant to its revolving credit facility.

Credit Agreements

MRC Energy Company

On September 28, 2012, the Company amended and restated its revolving credit facility with the lenders party 

thereto, led by Royal Bank of Canada (“RBC”) as administrative agent (the “Credit Agreement”). MRC Energy 
Company, a subsidiary of Matador that directly or indirectly holds the ownership interests in the Company’s other 
operating subsidiaries, other than its less-than-wholly-owned subsidiaries, is the borrower under the Credit 
Agreement. Borrowings are secured by mortgages on at least 80% of the Company’s proved oil and natural gas
properties and by the equity interests of certain of MRC Energy Company’s wholly-owned subsidiaries, which are 
also guarantors. San Mateo and its subsidiaries are not guarantors of the Credit Agreement. In addition, all
obligations under the Credit Agreement are guaranteed by Matador, the parent corporation. Various commodity 
hedging agreements with certain of the lenders under the Credit Agreement (or affiliates thereof) are also secured
by the collateral of and guaranteed by certain eligible subsidiaries of MRC Energy Company. The Credit Agreement
matures October 31, 2023.

F-24

MATADOR RESOURCES COMPANY  

NOTE 7 — DEBT — Continued

The borrowing base under the Credit Agreement is determined semi-annually as of May 1 and November 1

by the lenders based primarily on the estimated value of the Company’s proved oil and natural gas reserves
at December 31 and June 30 of each year, respectively. The Company and the lenders may each request an 
unscheduled redetermination of the borrowing base once between scheduled redetermination dates.

In February 2020, the lenders under the Credit Agreement completed their review of the Company’s proved 
oil and natural gas reserves, and, as a result, the borrowing base was reaffirmed at $900.0 million. The Company
elected to increase the borrowing commitment from $500.0 million to $700.0 million, and the maximum
facility amount remained $1.5 billion. The Company also added two new banks to the lending group as part 
of this redetermination process. This February 2020 redetermination constituted the regularly scheduled May 1
redetermination. In October 2020, the lenders completed their review of the Company’s proved oil and natural
gas reserves, and, as a result, the borrowing base was reaffirmed at $900.0 million. The Company elected to keep 
the borrowing commitment at $700.0 million, the maximum facility amount remained $1.5 billion and no changes 
were made to the terms of the Credit Agreement. This October 2020 redetermination constituted the regularly 
scheduled November 1 redetermination. Borrowings under the Credit Agreement are limited to the lowest of the
borrowing base, the maximum facility amount and the elected borrowing commitment (subject to compliance
with the covenant noted below).

In the event of an increase in the elected commitment, the Company is required to pay a fee to the lenders equal 

to a percentage of the amount of the increase, which is determined based on market conditions at the time of the 
increase. If, upon a redetermination of the borrowing base, the borrowing base were to be less than the outstanding 
borrowings under the Credit Agreement at such time, the Company would be required to provide additional 
collateral satisfactory in nature and value to the lenders to increase the borrowing base to an amount sufficient to
cover such excess or to repay the deficit in equal installments over a period of six months.

Total deferred loan costs were $1.7 million at December 31, 2020, and these costs are being amortized over the

term of the Credit Agreement. The Company’s effective interest rate under the Credit Agreement was 1.90% at 
December 31, 2020. At December 31, 2020, the Company had $440.0 million in borrowings outstanding under the
Credit Agreement and approximately $45.8 million in outstanding letters of credit issued pursuant to the Credit 
Agreement. Between December 31, 2020 and February 23, 2021, the Company repaid an additional $10.0 million 
of borrowings outstanding under the Credit Agreement.

Borrowings under the Credit Agreement may be in the form of a base rate loan or a Eurodollar loan. If the
Company borrows funds as a base rate loan, such borrowings will bear interest at a rate equal to the greatest of
(i) the prime rate for such day, (ii) the Federal Funds Effective Rate (as defined in the Credit Agreement) on such 
day, plus 0.50%, and (iii) the daily adjusting LIBOR rate (as defined in the Credit Agreement) plus 1.0% plus, in each 
case, an amount ranging from 0.25% to 1.25% per annum depending on the level of borrowings under the
Credit Agreement. If the Company borrows funds as a Eurodollar loan, such borrowings will bear interest at a rate 
equal to (x) the reserve adjusted LIBOR Rate (as defined in the Credit Agreement) plus (y) an amount ranging
from 1.25% to 2.25% per annum depending on the level of borrowings under the Credit Agreement. The interest 
period for Eurodollar borrowings may be one, two, three or six months as designated by the Company. If the
Company has outstanding borrowings under the Credit Agreement and interest rates increase, so will the
Company’s interest costs, which may have a material adverse effect on the Company’s results of operations and
financial condition.

F-25    

NOTE 7 — DEBT — Continued

A commitment fee of 0.375% to 0.50% per annum, depending on the level of borrowings under the Credit

Agreement, is also paid quarterly in arrears. The Company includes this commitment fee, any amortization
of deferred financing costs (including origination, borrowing base increase and amendment fees) and annual
agency fees, if any, as interest expense and in its interest rate calculations and related disclosures. The Credit
Agreement requires the Company to maintain a debt to EBITDA ratio, which is defined as debt outstanding (net of 
up to $50 million of cash or cash equivalents) divided by a rolling four quarter EBITDA calculation, of 4.00 or less.

Subject to certain exceptions, the Credit Agreement contains various covenants that limit the Company’s and

its restricted subsidiaries’ ability to take certain actions, including, but not limited to, the following:

•

incur indebtedness or grant liens on any of the Company’s assets;

• enter into commodity hedging agreements;

• declare or pay dividends, distributions or redemptions;

• merge or consolidate;

• make any loans or investments;

• engage in transactions with affiliates;

• engage in certain asset dispositions, including a sale of all or substantially all of the Company’s assets; and

•

take certain actions with respect to the Company’s senior unsecured notes.

If an event of default exists under the Credit Agreement, the lenders will be able to accelerate the maturity
of the borrowings and exercise other rights and remedies. Events of default include, but are not limited to, the
following events:

•

•

failure to pay any principal or interest on the outstanding borrowings or any reimbursement obligation under
any letter of credit when due or any fees or other amounts within certain grace periods;

failure to perform or otherwise comply with the covenants and obligations in the Credit Agreement or other
loan documents, subject, in certain instances, to certain grace periods;

• bankruptcy or insolvency events involving the Company or its subsidiaries; and

• a change of control, as defined in the Credit Agreement.

The Company believes that it was in compliance with the terms of the Credit Agreement at December 31, 2020.

San Mateo Midstream, LLC

On December 19, 2018, San Mateo I entered into a $250.0 million credit facility led by The Bank of Nova Scotia, 

as administrative agent (the “San Mateo Credit Facility”), and including all lenders party to the Credit Agreement
at that time. The San Mateo Credit Facility, which matures December 19, 2023, includes an accordion feature,
which provides for potential increases to up to $400.0 million. The San Mateo Credit Facility is non-recourse with
respect to Matador and its wholly-owned subsidiaries, but is guaranteed by San Mateo’s subsidiaries and secured 
by substantially all of San Mateo’s assets, including real property. At December 31, 2020, the lender commitments 
under the San Mateo Credit Facility were $375.0 million (subject to San Mateo’s compliance with the covenants 
noted below).

Total deferred loan costs were $2.1 million at December 31, 2020, and these costs are being amortized over the

term of the San Mateo Credit Facility. San Mateo’s effective interest rate under the San Mateo Credit Facility
was 2.15% at December 31, 2020. At December 31, 2020, San Mateo had $334.0 million in borrowings outstanding
under the San Mateo Credit Facility and $9.0 million in outstanding letters of credit issued pursuant to the
San Mateo Credit Facility. Between December 31, 2020 and February 23, 2021, San Mateo repaid $11.0 million 
in borrowings outstanding under the San Mateo Credit Facility.

Borrowings under the San Mateo Credit Facility may be in the form of a base rate loan or a Eurodollar loan.

If San Mateo borrows funds as a base rate loan, such borrowings will bear interest at a rate equal to the greatest of
(i) the prime rate for such day, (ii) the Federal Funds Effective Rate (as defined in the San Mateo Credit Facility) on 
such day, plus 0.50%, and (iii) the Adjusted LIBO Rate (as defined in the San Mateo Credit Facility) plus 1.0% plus,
in each case, an amount ranging from 0.50% to 1.50% per annum depending on San Mateo’s Consolidated Total 
Leverage Ratio (as defined in the San Mateo Credit Facility). If San Mateo borrows funds as a Eurodollar loan,
such borrowings will bear interest at a rate equal to (x) the Adjusted LIBO Rate for the chosen interest period plus 
(y) an amount ranging from 1.50% to 2.50% per annum depending on San Mateo’s Consolidated Total Leverage
Ratio. If San Mateo has outstanding borrowings under the San Mateo Credit Facility and interest rates increase,
so will San Mateo’s interest costs, which may have a material adverse effect on San Mateo’s results of operations
and financial condition.

A commitment fee of 0.30% to 0.50% per annum, depending on the unused availability under the San Mateo
Credit Facility, is also paid quarterly in arrears. The Company includes this commitment fee, any amortization of 
deferred financing costs (including origination and amendment fees) and annual agency fees, if any, as interest 
expense and in its interest rate calculations and related disclosures. The San Mateo Credit Facility requires San
Mateo to maintain a debt to EBITDA ratio, which is defined as total consolidated funded indebtedness outstanding 
(as defined in the San Mateo Credit Facility) divided by a rolling four quarter EBITDA calculation, of 5.00 or less,
subject to certain exceptions. The San Mateo Credit Facility also requires San Mateo to maintain an interest
coverage ratio, which is defined as a rolling four quarter EBITDA calculation divided by San Mateo’s consolidated 
interest expense, of 2.50 or more. The San Mateo Credit Facility also restricts the ability of San Mateo to distribute
cash to its members if San Mateo’s liquidity is less than 10% of the lender commitments under the San Mateo
Credit Facility.

Subject to certain exceptions, the San Mateo Credit Facility contains various covenants that limit San Mateo’s 

and its restricted subsidiaries’ ability to take certain actions, including, but not limited to, the following:

• merge or consolidate;

• make any loans or investments;

• engage in transactions with affiliates;

• engage in certain asset dispositions, including a sale of all or substantially all of San Mateo’s assets; and

•

issue equity interests in San Mateo or its subsidiaries.

If an event of default exists under the San Mateo Credit Facility, the lenders will be able to accelerate the 

maturity of the borrowings and exercise other rights and remedies. Events of default include, but are not limited to,
the following events:

•

•

failure to pay any principal or interest on the outstanding borrowings or any reimbursement obligation under
any letter of credit when due or any fees or other amounts within certain grace periods;

The Company believes that San Mateo was in compliance with the terms of the San Mateo Credit Facility at 

December 31, 2020.

Senior Unsecured Notes

On April 14, 2015, Matador issued $400.0 million of 6.875% senior notes due 2023 (the “Original 2023 Notes”)

in a private placement at par value. The Company received net proceeds of approximately $391.0 million, after 
deducting the initial purchasers’ discounts and offering expenses. The Original 2023 Notes were later exchanged 
for a like principal amount of 6.875% senior notes due 2023 (the “2023 Exchange Notes”) that were registered 
under the Securities Act of 1933, as amended (the “Securities Act”), at par value. On December 9, 2016, Matador 
issued $175.0 million of 6.875% senior notes due 2023 (the “Additional 2023 Notes”) in a private placement,
at 105.5% of par, plus accrued interest from October 15, 2016, resulting in an effective interest rate of 5.5%. The
Company received net proceeds of approximately $181.5 million, including the issue premium, but after 
deducting the initial purchasers’ discounts and estimated offering expenses and excluding accrued interest paid 
by buyers of the Additional 2023 Notes. The Additional 2023 Notes were later exchanged for a like principal amount 
of 6.875% senior notes due 2023 that were registered under the Securities Act (together with the 2023
Exchange Notes, the “2023 Notes”).

MATADOR RESOURCES COMPANY  

NOTE 7 — DEBT — Continued

On August 21, 2018, the Company issued $750.0 million of 5.875% senior notes due 2026 (the “Original 2026

Notes”) in a private placement at par value (the “2026 Notes Offering”). The Company received net proceeds of
approximately $740.0 million, after deducting the initial purchasers’ discounts and offering expenses. In conjunction 
with the 2026 Notes Offering, in August and September 2018, respectively, the Company completed a tender
offer to purchase for cash and subsequent redemption of all of the 2023 Notes (the “2023 Notes Tender Offer and
Redemption”). The Company used a portion of the net proceeds from the 2026 Notes Offering to fund the 
2023 Notes Tender Offer and Redemption. In connection with the 2023 Notes Tender Offer and Redemption, the 
Company incurred a loss of $31.2 million, including total payments of $30.4 million to holders of the 2023 
Notes as a result of the tender premium and the required 105.156% redemption price payable pursuant to the
2023 Notes indenture.

On October 4, 2018, the Company issued an additional $300.0 million of 5.875% senior notes due 2026 (the

“Additional 2026 Notes”). The Additional 2026 Notes were issued pursuant to, and are governed by, the same
indenture governing the Original 2026 Notes (the “Indenture”). The Additional 2026 Notes were issued at 100.5%
of par, plus accrued interest from August 21, 2018. The Company received net proceeds from this offering of
approximately $297.3 million, including the issue premium, but after deducting the initial purchasers’ discounts
and estimated offering expenses and excluding accrued interest from August 21, 2018 paid by the initial purchasers
of the Additional 2026 Notes. The proceeds from this offering were used to repay a portion of the outstanding
borrowings under the Credit Agreement, which were incurred in connection with the BLM Acquisition.

In December 2018, the Company exchanged substantially all of the Original 2026 Notes and Additional 2026 

Notes for a like principal amount of 5.875% senior notes due 2026 that were registered under the Securities 
Act (the “Notes”). The terms of the Notes are substantially the same as the terms of the Original 2026 Notes and
Additional 2026 Notes except that the transfer restrictions, registration rights and provisions for additional 
interest relating to the Original 2026 Notes and Additional 2026 Notes do not apply to the Notes. The Notes will 
mature September 15, 2026, and interest is payable on the Notes semi-annually in arrears on each March 15 and 
September 15. The Notes are guaranteed on a senior unsecured basis by certain subsidiaries of the Company 
(the “Guarantors”). San Mateo and its subsidiaries are not Restricted Subsidiaries (as defined in the Indenture) or 
Guarantors of the Notes.

On or after September 15, 2021, the Company may redeem all or a part of the Notes at any time or from time 
to time at the following redemption prices (expressed as percentages of principal amount) plus accrued and unpaid 
interest, if any, to the applicable redemption date, if redeemed during the twelve-month period beginning on
September 15 of the years indicated below:

(i)

the principal amount thereof, plus

(ii)

the excess, if any, of (a) the present value at such time of (1) the redemption price of such Notes at

Treasury Rate (as defined in the Indenture) plus 50 basis points, over (b) the principal amount of such 
Notes, plus

(iii) accrued and unpaid interest, if any, to the redemption date.

Subject to certain exceptions, the Indenture contains various covenants that limit the Company’s ability to take

certain actions, including, but not limited to, the following:

•

incur additional indebtedness;

• sell assets;

• pay dividends or make certain investments;

• create liens that secure indebtedness;

• enter into transactions with affiliates; and

• merge or consolidate with another company.

In the case of an event of default arising from certain events of bankruptcy or insolvency with respect to

Matador, any Restricted Subsidiary (as defined in the Indenture) that is a Significant Subsidiary (as defined in the
Indenture) or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary,
all outstanding Notes will become due and payable immediately without further action or notice. If any other event 
of default occurs and is continuing, the trustee or the holders of at least 25% in principal amount of the then
outstanding Notes may declare all the Notes to be due and payable immediately. Events of default include, but are
not limited to, the following events:

• default for 30 days in the payment when due of interest on the Notes;

• default in the payment when due of the principal of, or premium, if any, on the Notes;

•

NOTE 8 — INCOME TAXES — Continued

As a result of the net capitalized costs of the Company’s oil and natural gas properties less related deferred 
income taxes exceeding the full-cost ceiling during the year ended December 31, 2020, the Company recorded an
impairment charge of $684.7 million, exclusive of tax effect, to the net capitalized costs of its oil and natural gas
properties. Due to these impairment charges, at December 31, 2020, the Company’s deferred tax assets exceeded 
its deferred tax liabilities. As a result, the Company established a valuation allowance against most of the deferred 
tax assets. The remaining net deferred tax asset at December 31, 2020 relates to state taxes, for which the 
deferred taxes were determined to be more likely than not to be utilized.

the material positions taken would more likely than not be sustained by examination. Therefore, at December 31,
2020, the Company had not established any reserves for, nor recorded any unrecognized benefits related to,
uncertain tax positions.

MATADOR RESOURCES COMPANY  

NOTE 9 — STOCK-BASED COMPENSATION

Stock Options, Restricted Stock, Restricted Stock Units, Stock and Performance Awards

In 2003, the Company’s Board of Directors and shareholders approved the 2003 Incentive Plan. The 2003 

Incentive Plan, as amended, provided that a maximum of 3,481,569 shares of common stock in the aggregate could
be issued pursuant to options or restricted stock grants. In 2012, the Board of Directors adopted and shareholders
approved the 2012 Incentive Plan. The 2012 Incentive Plan provided for a maximum of 8,700,000 shares of
common stock in the aggregate that could be issued pursuant to options, restricted stock, stock appreciation rights,
restricted stock units or other performance award grants.

In 2019, the Board of Directors adopted and shareholders approved the 2019 Incentive Plan. As of December 31, 

2020, the 2019 Incentive Plan provided for a maximum of 1,940,386 shares of common stock in the aggregate that
may be issued pursuant to grants of options, restricted stock, stock appreciation rights, restricted stock units or 
other performance award grants. The persons eligible to receive awards under the 2019 Incentive Plan include 
employees, directors, contractors or advisors of the Company. The primary purpose of the 2019 Incentive Plan is
to attract and retain key employees, directors, contractors or advisors of the Company. With the adoption of the
2019 Incentive Plan, the Company does not expect to make any future awards under the 2003 Incentive Plan or the 
2012 Incentive Plan, but both plans will remain in place until all awards outstanding under such plans have been
settled. As of December 31, 2020, no awards remained outstanding under the 2003 Incentive Plan.

The 2012 Incentive Plan and the 2019 Incentive Plan are administered by the independent members of the Board 

of Directors, who, upon recommendation of the Strategic Planning and Compensation Committee of the Board of 
Directors, determine the number of options, restricted shares or other awards to be granted, the effective dates, the
terms of the grants and the vesting periods. The Company typically uses newly issued shares of common stock 
to satisfy option exercises or restricted share grants.

During the year ended December 31, 2019, the Company began granting both equity-based and liability-based 
awards under the 2019 Incentive Plan. The fair value of equity-based awards is fixed at the grant date, while the fair 
value of liability-based awards is remeasured at each reporting period.

Stock Options

Under the 2012 Incentive Plan and the 2019 Incentive Plan, stock option awards have been granted and are 
outstanding to purchase the Company’s common stock at an exercise price equal to the fair market value on the
date of grant, a typical vesting period of three or four years and a typical maximum term of five, six or 10 years. 
The 2012 Incentive Plan defines fair market value as the closing price of Matador’s common stock on the date of 
grant. Under the 2019 Incentive Plan, such fair market value of a stock option is determined using the closing 
price of Matador’s common stock on the trading day prior to the date of grant. All remaining option awards granted
under the 2003 Incentive Plan were settled in the first quarter of 2020.

The Company estimated the future volatility of its common stock using the historical value of its stock for a

period of time commensurate with the expected term of the stock option. The expected term was estimated 
using the simplified method outlined in Staff Accounting Bulletin Topic 14. The risk-free interest rate is the rate 
for constant yield U.S. Treasury securities with a term to maturity that is consistent with the expected term
of the award.

Summarized information about stock options outstanding at December 31, 2020 under the 2012 Incentive Plan

Common Stock 

On May 17, 2018, the Company completed a public offering of 7,000,000 shares of its common stock. After 
deducting offering costs totaling approximately $0.2 million, the Company received net proceeds of approximately
$226.4 million.

Treasury Stock

On October 22, 2020, October 24, 2019 and October 25, 2018, Matador’s Board of Directors canceled all of
the shares of treasury stock outstanding as of September 30, 2020, 2019 and 2018, respectively. These shares were 
restored to the status of authorized but unissued shares of common stock of the Company.

The shares of treasury stock outstanding at December 31, 2020, 2019 and 2018 represent forfeitures of

non-vested restricted stock awards and forfeitures of fully vested restricted stock awards due to net share settlements 
with employees.

Preferred Stock

The Company’s Amended and Restated Certificate of Formation authorizes 2,000,000 shares of preferred stock.

Before any such shares are issued, the Board of Directors shall fix and determine the designations, preferences, 
limitations and relative rights, including voting rights of the shares of each such series.

NOTE 12 — DERIVATIVE FINANCIAL INSTRUMENTS

From time to time, the Company uses derivative financial instruments to mitigate its exposure to commodity
price risk associated with oil, natural gas and NGL prices. The Company records derivative financial instruments on
its consolidated balance sheets as either assets or liabilities measured at fair value. The Company has elected
not to apply hedge accounting for its existing derivative financial instruments. As a result, the Company recognizes 
the change in derivative fair value between reporting periods currently in its consolidated statements of operations
as an unrealized gain or loss. The fair value of the Company’s derivative financial instruments is determined using 
industry-standard models that consider various inputs including: (i) quoted forward prices for commodities, (ii) time
value of money and (iii) current market and contractual prices for the underlying instruments, as well as other
relevant economic measures. The Company has evaluated and considered the credit standings of its counterparties 
in determining the fair value of its derivative financial instruments.

At December 31, 2020, the Company had various costless collar and swap contracts open and in place to

mitigate its exposure to oil and natural gas price volatility, each with a specific term (calculation period), notional 
quantity (volume hedged) and price floor and ceiling and fixed price for the swaps. At December 31, 2020, each 
contract was set to expire at varying times during 2021 and 2022. The Company had no open contracts associated 
with NGL prices at December 31, 2020.

NOTE 13 — FAIR VALUE MEASUREMENTS

The Company measures and reports certain financial and non-financial assets and liabilities on a fair value basis. 

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction 
between market participants at the measurement date (exit price). Fair value measurements are classified and
disclosed in one of the following categories.

Level 1 Unadjusted quoted prices for identical, unrestricted assets or liabilities in active markets.

Level 2 Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for

substantially the full term of the asset or liability. This category includes those derivative instruments that are 
valued with industry standard models that consider various inputs, including: (i) quoted forward prices for 
commodities, (ii) time value of money and (iii) current market and contractual prices for the underlying 
instruments, as well as other relevant economic measures. Substantially all of these inputs are observable
in the marketplace throughout the full term of the derivative instrument and can be derived from 
observable data or supported by observable levels at which transactions are executed in the marketplace.

Level 3 Unobservable inputs that are not corroborated by market data that reflect a company’s own market 

assumptions.

Financial and non-financial assets and liabilities are classified based on the lowest level of input that is significant

to the fair value measurement. The assessment of the significance of a particular input to the fair value 
measurement requires judgment, which may affect the valuation of the fair value of assets and liabilities and their 
placement within the fair value hierarchy levels.

The following tables summarize the valuation of the Company’s financial assets and liabilities that were accounted
for at fair value on a recurring basis in accordance with the classifications provided above as of December 31, 2020
and 2019 (in thousands).

NOTE 13 — FAIR VALUE MEASUREMENTS — Continued

Other Fair Value Measurements

At December 31, 2020 and 2019, the carrying values reported on the consolidated balance sheets for accounts

receivable, prepaid expenses and other current assets, accounts payable, accrued liabilities, royalties payable, 
amounts due to affiliates, advances from joint interest owners, amounts due to joint ventures and other current
liabilities approximated their fair values due to their short-term maturities.

At December 31, 2020 and 2019, the carrying value of borrowings under the Credit Agreement and the

San Mateo Credit Facility approximated their fair value as both are subject to short-term floating interest rates that 
reflect market rates available to the Company at the time and are classified at Level 2 in the fair value hierarchy.

At December 31, 2020 and 2019, the fair value of the Notes was $1.03 billion and $1.06 billion, respectively, 

based on quoted market prices, which represent Level 1 inputs in the fair value hierarchy.

Certain assets and liabilities are measured at fair value on a nonrecurring basis, including assets and liabilities
acquired in a business combination, lease and well equipment inventory when the market value is determined to be
lower than the cost of the inventory and other property and equipment that are reduced to fair value when they 
are impaired or held for sale. The Company recorded no impairment to its lease and well equipment inventory or 
other property and equipment in 2020 and 2019.

NOTE 14 — COMMITMENTS AND CONTINGENCIES

Processing, Transportation and Produced Water Disposal Commitments

Firm Commitments

From time to time, the Company enters into agreements with third parties whereby the Company commits to

deliver anticipated natural gas and oil production and produced water from certain portions of its acreage for 
gathering, transportation, processing, fractionation, sales and disposal. The Company paid approximately $46.0 million
and $28.7 million for deliveries under these agreements during the years ended December 31, 2020 and 2019, 
respectively. Certain of these agreements contain minimum volume commitments. If the Company does not meet
the minimum volume commitments under these agreements, it will be required to pay certain deficiency fees. 
If the Company ceased operations in the areas subject to these agreements at December 31, 2020, the total deficiencies
required to be paid by the Company under these agreements would be approximately $523.1 million, in addition to 
the future commitments and the San Mateo commitments described below.

Future Commitments

In October 2019, the Company entered into a 15-year, fixed-fee natural gas transportation agreement whereby 

the Company committed to deliver a portion of the residue gas production at the tailgate of the Black River
Processing Plant to transport through the counterparty’s pipeline. The agreement began when the counterparty’s
pipeline was placed in service, which occurred during the first quarter of 2021. Now that the pipeline has been 
placed in service, the Company owes the fees to transport the committed volume whether or not the committed
volume is transported through the counterparty’s pipeline. The minimum contractual obligation was approximately 
$106.9 million when the pipeline was placed in service.

NOTE 14 — COMMITMENTS AND CONTINGENCIES — Continued

San Mateo Commitments

In February 2017, the Company dedicated its current and certain future leasehold interests in the Rustler Breaks

and Wolf asset areas pursuant to 15-year, fixed-fee oil, natural gas and produced water gathering and produced
water disposal agreements with subsidiaries of San Mateo I. In addition, the Company dedicated its current and 
certain future leasehold interests in the Rustler Breaks asset area pursuant to a 15-year, fixed-fee natural gas 
processing agreement (collectively with the gathering and produced water disposal agreements, the “Operational 
Agreements”). San Mateo provides the Company with firm service under each of the Operational Agreements 
in exchange for certain minimum volume commitments. The remaining minimum contractual obligation under the
Operational Agreements at December 31, 2020 was approximately $153.5 million.

In connection with the February 2019 formation of San Mateo II, the Company dedicated to San Mateo
acreage in the Greater Stebbins Area and the Stateline asset area pursuant to 15-year, fixed-fee oil, natural gas 
and produced water gathering, natural gas processing and produced water disposal agreements (collectively, 
the “San Mateo II Operational Agreements”). San Mateo provides the Company with firm service under each of the 
San Mateo II Operational Agreements in exchange for certain minimum volume commitments. The remaining
minimum contractual obligation under the San Mateo II Operational Agreements at December 31, 2020 was 
approximately $340.3 million.

In June 2019, a subsidiary of San Mateo entered into an agreement with third parties for the engineering, 
procurement, construction and installation of an expansion of the Black River Processing Plant, including required 
compression. The expansion was placed in service in the third quarter of 2020. San Mateo’s total commitments
under this agreement were $81.3 million. San Mateo paid approximately $41.2 million under this agreement
during the year ended December 31, 2020. As of December 31, 2020, there were no remaining obligations under
this agreement.

Other Commitments

The Company does not own or operate its own drilling rigs, but instead enters into contracts with third parties

for such drilling rigs. These contracts establish daily rates for the drilling rigs and the term of the Company’s 
commitment for the drilling services to be provided. The Company would incur a termination obligation if the
Company elected to terminate a contract and if the drilling contractor were unable to secure replacement work 
for the contracted drilling rigs at the same daily rates being charged to the Company prior to the end of their 
respective contract terms. The Company’s undiscounted minimum outstanding aggregate termination obligations 
under its drilling rig contracts were approximately $20.6 million at December 31, 2020.

At December 31, 2020, the Company had outstanding commitments to drill and complete and to participate in
the drilling and completion of various operated and non-operated wells. If all of these wells are drilled and completed 
as proposed, the Company’s undiscounted minimum outstanding aggregate commitments for its participation 
in these operated and non-operated wells were approximately $44.6 million at December 31, 2020. The Company
expects these costs to be incurred within the next three to five years.

Legal Proceedings

The Company is a party to several legal proceedings encountered in the ordinary course of its business. While 
the ultimate outcome and impact to the Company cannot be predicted with certainty, in the opinion of management,
it is remote that these legal proceedings will have a material adverse impact on the Company’s financial condition,
results of operations or cash flows.

NOTE 16 — SEGMENT INFORMATION

The Company operates in two business segments: (i) exploration and production and (ii) midstream. The

exploration and production segment is engaged in the exploration, development, production and acquisition of oil
and natural gas resources in the United States and is currently focused primarily on the oil and liquids-rich portion
of the Wolfcamp and Bone Spring plays in the Delaware Basin in Southeast New Mexico and West Texas. The 
Company also operates in the Eagle Ford shale play in South Texas and the Haynesville shale and Cotton Valley plays
in Northwest Louisiana. The midstream segment conducts midstream operations in support of the Company’s
exploration, development and production operations and provides natural gas processing, oil transportation services, 
oil, natural gas and produced water gathering services and produced water disposal services to third parties. 
Substantially all of the Company’s midstream operations in the Rustler Breaks, Wolf and Stateline asset areas
and the Greater Stebbins Area in the Delaware Basin are conducted through San Mateo (see Note 6).

The following tables present selected financial information for the periods presented regarding the Company’s 

business segments on a stand-alone basis, corporate expenses that are not allocated to a segment and the
consolidation and elimination entries necessary to arrive at the financial information for the Company on a
consolidated basis (in thousands). On a consolidated basis, midstream services revenues consist primarily of those 
revenues from midstream operations related to third parties, including working interest owners in the Company’s
operated wells. All midstream services revenues associated with Company-owned production are eliminated in
consolidation. In evaluating the operating results of the exploration and production and midstream segments, 
the Company does not allocate certain expenses to the individual segments, including general and administrative 
expenses. Such expenses are reflected in the column labeled “Corporate.”

Property acquisition costs are costs incurred to purchase, lease or otherwise acquire oil and natural gas

properties, including both unproved and unevaluated leasehold and purchases of reserves in place. For the years 
ended December 31, 2020, 2019 and 2018, most of the Company’s property acquisition costs resulted from the 
acquisition of unproved and unevaluated leasehold and mineral interests.

Exploration costs are costs incurred in identifying areas of these oil and natural gas properties that may warrant 

further examination and in examining specific areas that are considered to be prospective for oil and natural gas, 
including costs of drilling exploratory wells, geological and geophysical costs and costs of carrying and retaining
unproved and unevaluated properties. Exploration costs may be incurred before or after acquiring the related oil
and natural gas properties. For the years ended December 31, 2020, 2019 and 2018, the Company capitalized zero,
$2.9 million and $17.7 million, respectively, of geological and geophysical costs, which are included as exploration 
costs in the table above.

Development costs are costs incurred to obtain access to proved reserves and to provide facilities for extracting, 
treating, gathering and storing oil and natural gas. Development costs include the costs of preparing well locations 
for drilling, drilling and equipping development wells and acquiring, constructing and installing production facilities.

Costs incurred also include newly established asset retirement obligations, as well as changes to asset

retirement obligations resulting from revisions in cost estimates or abandonment dates. Asset retirement obligations 
included in the table above were a reduction of $0.2 million and increases of $4.3 million and $4.0 million for the
years ended December 31, 2020, 2019 and 2018, respectively. Capitalized general and administrative expenses that 
are directly related to acquisition, exploration and development activities are also included in the table above.
The Company capitalized $30.0 million, $31.1 million and $28.3 million of these internal costs for the years ended 
December 31, 2020, 2019 and 2018, respectively, excluding midstream-related capitalized general and 
administrative expenses. Capitalized interest expense for qualifying projects is also included in the table above. 
The Company capitalized $5.0 million, $7.6 million and $8.8 million of its interest expense for the years ended
December 31, 2020, 2019 and 2018, respectively, excluding midstream-related capitalized interest expense.

SUPPLEMENTAL OIL AND NATURAL GAS DISCLOSURES — Continued

Oil and Natural Gas Reserves

Proved reserves are estimated quantities of oil and natural gas that geological and engineering data demonstrate

with reasonable certainty to be recoverable in future years from known reservoirs using existing economic and
operating conditions. Estimating oil and natural gas reserves is complex and inexact because of the numerous
uncertainties inherent in the process. The process relies on interpretations of available geological, geophysical, 
petrophysical, engineering and production data. The extent, quality and reliability of both the data and the associated 
interpretations of that data can vary. The process also requires certain economic assumptions, including, but not 
limited to, oil and natural gas prices, drilling, completion and operating expenses, capital expenditures and taxes.
Actual future production, oil and natural gas prices, revenues, taxes, development expenditures, operating
expenses and quantities of recoverable oil and natural gas most likely will vary from the Company’s estimates.

The Company reports its production and proved reserves in two streams: oil and natural gas, including both dry

and liquids-rich natural gas. Where the Company produces liquids-rich natural gas, such as in the Wolfcamp and
Bone Spring plays in the Delaware Basin in Southeast New Mexico and West Texas and the Eagle Ford shale in 
South Texas, the economic value of the NGLs associated with the natural gas is included in the estimated wellhead 
natural gas price on those properties where the NGLs are extracted and sold. The Company’s oil and natural gas
reserves estimates for the years ended December 31, 2020, 2019 and 2018 were prepared by the Company’s
engineering staff in accordance with guidelines established by the SEC and then audited for their reasonableness
and conformance with SEC guidelines by Netherland, Sewell & Associates, Inc., independent reservoir engineers.

Oil and natural gas reserves are estimated using then-current operating and economic conditions, with no
provision for price and cost escalations in future periods except by contractual arrangements. The commodity 
prices used to estimate oil and natural gas reserves are based on unweighted, arithmetic averages of first-
day-of-the-month oil and natural gas prices for the previous 12-month period. For the period from January through 
December 2020, these average oil and natural gas prices were $36.04 per Bbl and $1.99 per MMBtu, respectively.
For the period from January through December 2019, these average oil and natural gas prices were $52.19 per Bbl
and $2.58 per MMBtu, respectively. For the period from January through December 2018, these average oil and 
natural gas prices were $62.04 per Bbl and $3.10 per MMBtu, respectively.

The Company’s net ownership in estimated quantities of proved oil and natural gas reserves and changes in net

proved reserves are summarized as follows. All of the Company’s oil and natural gas reserves are attributable to 
properties located in the United States. The estimated reserves shown below are proved reserves only and do not
include any value for unproved reserves classified as probable or possible reserves that might exist for these 
properties, nor do they include any consideration that could be attributed to interests in unevaluated acreage beyond 
those tracts for which reserves have been estimated. In the tables presented throughout this section, natural gas
is converted to oil equivalent using the ratio of one Bbl of oil to six Mcf of natural gas.

The following is a discussion of the changes in the Company’s proved oil and natural gas reserves estimates for

the years ended December 31, 2020, 2019 and 2018.

The Company’s proved oil and natural gas reserves increased to 270,332 MBOE at December 31, 2020 from
252,531 MBOE at December 31, 2019. The Company’s proved oil and natural gas reserves increased by 45,315 MBOE
and the Company produced 27,514 MBOE during the year ended December 31, 2020, resulting in a net increase 
of 17,801 MBOE. The Company’s proved oil and natural gas reserves increased by 35,297 MBOE during 2020 as a
result of extensions and discoveries during the year, which were primarily attributable to drilling operations in the 
Wolfcamp and Bone Spring plays in the Delaware Basin in Southeast New Mexico and West Texas. The Company’s
proved oil and natural gas reserves increased by 9,828 MBOE during 2020 as a result of upward revisions of prior 
estimates, which were attributable to better-than-projected well performance from certain wells, but these upward
revisions were partially offset by downward revisions attributable to the lower weighted average oil and natural
gas prices used to estimate proved reserves in 2020, as compared to 2019. The Company’s proved developed oil
and natural gas reserves increased to 123,507 MBOE at December 31, 2020 from 105,710 MBOE at December 31, 
2019, primarily due to proved developed reserves added as a result of drilling operations in the Wolfcamp and 
Bone Spring plays in the Delaware Basin. At December 31, 2020, the Company’s proved reserves were made up of
approximately 59% oil and 41% natural gas and were approximately 46% proved developed and approximately
54% proved undeveloped.

and the Company produced 24,164 MBOE during the year ended December 31, 2019, resulting in a net increase 
of 37,218 MBOE. The Company’s proved oil and natural gas reserves increased by 58,616 MBOE during 2019 as a
result of extensions and discoveries during the year, which were primarily attributable to drilling operations in the 
Wolfcamp and Bone Spring plays in the Delaware Basin in Southeast New Mexico and West Texas. The Company’s 
proved oil and natural gas reserves increased by 5,073 MBOE during 2019 as a result of upward revisions of prior

to estimate proved reserves in 2019, as compared to 2018. The Company’s proved oil and natural gas reserves
decreased 2,307 MBOE in 2019 as a result of net divestitures of minerals-in-place primarily in the Eagle Ford shale
in South Texas and the Haynesville shale in Northwest Louisiana. The Company’s proved developed oil and natural
gas reserves increased to 105,710 MBOE at December 31, 2019 from 94,261 MBOE at December 31, 2018, 
primarily due to proved developed reserves added as a result of drilling operations in the Wolfcamp and Bone Spring

increase of 62,542 MBOE. The Company’s proved oil and natural gas reserves increased by 69,646 MBOE as a 
result of extensions and discoveries during the year, which were primarily attributable to drilling operations in the 
Wolfcamp and Bone Spring plays in the Delaware Basin in Southeast New Mexico and West Texas. The Company’s 
proved oil and natural gas reserves increased by 11,326 MBOE during 2018 as a result of upward revisions of 
prior estimates, which were attributable to better-than-projected well performance from certain wells and higher
weighted average oil and natural gas prices used to estimate proved reserves in 2018, as compared to 2017. 
The Company also added 596 MBOE in proved oil and natural gas reserves in 2018 as a result of purchases of
minerals-in-place in the Delaware Basin. The Company’s proved developed oil and natural gas reserves increased to
94,261 MBOE at December 31, 2018 from 68,651 MBOE at December 31, 2017, primarily due to proved developed

Standardized Measure of Discounted Future Net Cash Flows and Changes Therein Relating to Proved  
Oil and Natural Gas Reserves

The standardized measure of discounted future net cash flows relating to proved oil and natural gas reserves is
not intended to provide an estimate of the replacement cost or fair market value of the Company’s oil and natural gas 
properties. An estimate of fair market value would also take into account, among other things, the recovery of
reserves not presently classified as proved, anticipated future changes in prices and costs, potential improvements
in industry technology and operating practices, the risks inherent in reserves estimates and perhaps different 
discount rates.

As noted previously, for the period from January through December 2020, the unweighted, arithmetic averages 

of first-day-of-the-month oil and natural gas prices were $36.04 per Bbl and $1.99 per MMBtu, respectively. For 
the period from January through December 2019, the comparable average oil and natural gas prices were $52.19
per Bbl and $2.58 per MMBtu, respectively. For the period from January through December 2018, the comparable
average oil and natural gas prices were $62.04 per Bbl and $3.10 per MMBtu, respectively.

Future net cash flows were computed by applying these oil and natural gas prices, adjusted for all associated
transportation and gathering costs, gravity and energy content and regional price differentials, to year-end quantities 
of proved oil and natural gas reserves and accounting for any future production and development costs associated 
with producing these reserves; neither prices nor costs were escalated with time in these computations.

Future income taxes were computed by applying the statutory tax rate to the excess of future net cash flows

relating to proved oil and natural gas reserves less the tax basis of the associated properties. Tax credits and net
operating loss carryforwards available to the Company were also considered in the computation of future income
taxes. Future net cash flows after income taxes were discounted using a 10% annual discount rate to derive the
standardized measure of discounted future net cash flows.

The following table presents the standardized measure of discounted future net cash flows relating to proved oil 

and natural gas reserves for the years ended December 31, 2020, 2019 and 2018 (in thousands).

2020 ANNUAL REPORT

Additional Financial Information

ADJUSTED FREE CASH FLOW RECONCILIATION

This Annual Report 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 as 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. Adjusted free cash flow for San Mateo includes the combined financial results of San Mateo Midstream, LLC 
and San Mateo Midstream II, LLC prior to their October 2020 merger.
