GLOSSARY OF CERTAIN OIL AND NATURAL GAS TERMS

The following are abbreviations and definitions of terms commonly used in the oil and natural gas industry and within this report.

3-D seismic – An advanced technology method of detecting accumulation of hydrocarbons identified through a three-dimensional picture of the subsurface created
by the collection and measurement of the intensity and timing of sound waves transmitted into the earth as they reflect back to the surface.

Bbl – One barrel or 42 U.S. gallons liquid volume of oil or other liquid hydrocarbons.

Boe – Barrel of oil equivalent, determined using a ratio of six Mcf of natural gas equal to one barrel of oil equivalent. The ratio does not assume price equivalency
and, given price differentials, the price for a barrel of oil equivalent for natural gas differs significantly from the price for a barrel of oil.  A barrel of NGLs also
differs significantly in price from a barrel of oil.

Btu – British thermal unit, the quantity of heat required to raise the temperature of one pound of water by one-degree Fahrenheit.

Completion – The process of treating and hydraulically fracturing a drilled well followed by the installation of permanent equipment for the production of oil or
natural gas, or in the case of a dry hole, the reporting of abandonment to the appropriate regulatory agency.

Developed acreage – The number of acres which are allotted or assignable to producing wells or wells capable of production.

Development activities – Activities following exploration including the drilling and completion of additional wells and the installation of production facilities.

Development well – A well drilled within the proved area of an oil or natural gas reservoir to the depth of a stratigraphic horizon known to be productive.

Dry hole or well – A well found to be incapable of producing hydrocarbons economically.

Exploitation – A development or other project which may target proven or unproven reserves (such as probable or possible reserves), but which generally has a
lower risk than that associated with exploration projects.

Exploratory well – A well drilled to find and produce oil or natural gas reserves in an area or a potential reservoir not classified as proved.

Farm-in or Farm-out – An agreement whereby the owner of a working interest in an oil and natural gas lease assigns or contractually conveys, subject to future
assignment, the working interest or a portion thereof to another party who desires to drill on the leased acreage. Generally, the farmee is required to drill one or
more wells in order to earn its interest in the acreage. The farmor usually retains a royalty and/or an after-payout interest in the lease. The interest received by the
farmee is a “farm-in” while the interest transferred by the farmor is a “farm-out.”

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, as the case may be, in which a working interest is owned.

Horizontal drilling – A drilling technique that permits the operator to drill horizontally within a specified targeted reservoir and thus exposes a larger portion of the
producing horizon to a wellbore than would otherwise be exposed through conventional vertical drilling techniques.

Hydraulic fracture or Frac – A well stimulation method by which fluid, comprised largely of water and proppant (purposely sized particles used to hold open an
induced fracture) is injected downhole and into the producing formation at high pressures and rates in order to exceed the rock strength and create a fracture such
that the proppant material can be placed into the fracture to enhance the productive capability of the formation.

Injection well – A well which is used to inject gas, water, or liquefied petroleum gas under high pressure into a producing formation to maintain sufficient pressure
to produce the recoverable reserves.

Joint Operating Agreement or JOA – Any agreement between working interest owners concerning the duties and responsibilities of the operator and rights and
obligations of the non-operators.

MBbls – One thousand barrels of crude oil or other liquid hydrocarbons.

MBoe – One thousand barrels of oil equivalent, determined using a ratio of six Mcf of natural gas equal to one barrel of oil equivalent.

5

MMBoe – One million barrels of oil equivalent, determined using a ratio of six Mcf of natural gas equal to one barrel of oil equivalent.

MMBtu – One million Btu.

Mcf – One thousand cubic feet.

MMcf – One million cubic feet.

Net acres or net wells – The sum of the fractional working interests owned in gross acres or gross wells.

NGLs –  Natural  gas  liquids  measured  in  barrels.  NGLs  are  made  up  of  ethane,  propane,  isobutane,  normal  butane  and  natural  gasoline,  each  of  which  have
different uses and different pricing characteristics.

NYMEX – The New York Mercantile Exchange.

Plugging and abandonment or P&A – Refers to the sealing off of fluids in the strata penetrated by a well so that the fluids from one stratum will not escape into
another stratum or to the surface.

PV-10 –  The  present  value  of  estimated  future  revenues,  discounted  at  10%  annually,  to  be  generated  from  the  production  of  proved  reserves  determined  in
accordance with the SEC guidelines, net of estimated production and future development costs, using prices and costs as of the date of estimation without future
escalation, without giving effect to (i) non-property related expenses such as general and administrative expenses, debt service and future income tax expense, or
(ii) depreciation, depletion and amortization.

Productive well – A well that is found to be capable of producing hydrocarbons in sufficient quantities such that proceeds from the sale of such production exceeds
production expenses and taxes.

Proppant – A solid material, typically treated sand or man-made ceramic materials, designed to keep an induced hydraulic fracture open, during or following a
fracturing treatment.

Proved developed nonproducing reserves or PDNP – Hydrocarbons in a potentially producing horizon penetrated by a wellbore, the production of which has been
postponed pending completion activities and the 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 nonproducing reserves.

Proved developed producing reserves or PDP – Reserves that can be expected to be recovered from existing wells and completions with existing equipment and
operating methods.

Proved  developed  reserves  or PD  –  The  estimated  quantities  of  oil,  natural  gas  and  NGLs  that  geological  and  engineering  data  demonstrate  with  reasonable
certainty to be commercially recoverable in future years from known reservoirs under existing economic and operating conditions.

Proved reserves – Those 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. The area of the reservoir considered as proved includes (i) the area identified by
drilling and limited by fluid contacts, if any, and (ii) adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with
it and to contain economically producible oil or gas on the basis of available geoscience and engineering data. In the absence of data on fluid contacts, proved
quantities in a reservoir are limited by the lowest known hydrocarbons (“LKH”), as seen in a well penetration unless geoscience, engineering, or performance data
and reliable technology establishes a lower contact with reasonable  certainty. Where direct observation  from well penetrations  has defined a highest known oil
(“HKO”), elevation and the potential exists for an associated gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if
geoscience,  engineering,  or  performance  data  and  reliable  technology  establish  the  higher  contact  with  reasonable  certainty.  Reserves  which  can  be  produced
economically through application of improved recovery techniques (including, but not limited to, fluid injection) are included in the proved classification when (i)
successful  testing by a pilot project  in an area  of the reservoir  with properties  no more favorable  than in the reservoir  as a whole, the operation  of an installed
program in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes the reasonable certainty of the engineering analysis on
which  the  project  or  program  was  based;  and  (ii)  the  project  has  been  approved  for  development  by  all  necessary  parties  and  entities,  including  governmental
entities. Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price shall be the average
price during the 12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-

6

the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.

Proved undeveloped reserves or PUD  – 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. Reserves on undrilled acreage shall be limited to those directly offsetting development spacing areas that
are reasonably certain of production when drilled, unless evidence using reliable technology exists that establishes reasonable certainty of economic producibility
at  greater  distances.  Undrilled  locations  can  be  classified  as  having undeveloped  reserves  only  if a  development  plan  has been  adopted  indicating  that  they  are
schedule to be drilled within five years unless specific circumstances justify a longer time. Under no circumstances shall estimates for proved undeveloped reserves
be attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been
proved effective by actual projects in the same reservoir or an analogous reservoir, or by other evidence using reliable technology establishing reasonable certainty.

Recompletion – The completion for production of an existing well bore in another formation from that in which the well has been previously completed.

Re-engineering –  A  process  involving  a  comprehensive  review  of  the  mechanical  conditions  associated  with  wells  and  equipment  in  producing  fields.  Our  re-
engineering  practices  typically  result  in a capital  expenditure  plan which is implemented  over time  to workover (see below) and re-complete  wells and modify
down  hole  artificial  lift  equipment  and  surface  equipment  and  facilities.  The  programs  are  designed  specifically  for  individual  fields  to  increase  and  maintain
production, reduce down-time and mechanical failures, lower per-unit operating expenses, and therefore, improve field economics.

Reservoir – A 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 property entitling the owner to a share of oil or natural gas production free of costs of production.

SEC – United States Securities and Exchange Commission.

Shut-in reserves – Those reserves expected to be recovered from completion intervals that were open at the time the reserve was estimated but were not producing
due to market conditions, mechanical difficulties or because production equipment or pipelines were not yet installed. These reserves are included in the PDNP
category in our reserve report.

Standardized Measure – The present value of estimated future net revenue to be generated from the production of proved reserves, determined in accordance with
the rules and regulations of the SEC (using prices and costs in effect as of the date of estimation), less future development, production and income tax expenses,
and discounted at 10% per annum to reflect the timing of future net revenue.

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.

Working interest or WI – The ownership interest, generally defined in a JOA, that gives the owner the right to drill, produce and/or conduct operating activities on
the property and share in the sale of production, subject to all royalties, overriding royalties and other burdens and obligates the owner of the interest to share in all
costs of exploration, development operations and all risks in connection therewith.

Workover – Operations on a producing well to restore or increase production.

WTI – West Texas Intermediate light sweet crude oil, a benchmark in crude oil pricing.

Overview

PART I

Earthstone  Energy,  Inc.,  a  Delaware  corporation  (“Earthstone”  and  together  with  our  consolidated  subsidiaries,  the  “Company,”  “our,”  “we,”  “us,”  or  similar
terms), is a growth-oriented independent oil and gas company engaged in the acquisition and development of oil and gas reserves through activities that include the
acquisition, drilling and development of undeveloped leases, asset and corporate acquisitions and mergers. Our operations are all in the upstream segment of the oil
and natural gas industry and all our properties are onshore in the United States. At present, our assets are located in the Midland Basin of west Texas and the Eagle
Ford Trend of south Texas.

Our primary focus is concentrated in the Midland Basin of west Texas, a high oil and liquids rich resource basin which provides us with multiple horizontal targets
with proven production results, long-lived reserves and historically high drilling success rates.

IRM Acquisition

On  January  7,  2021,  Earthstone,  Earthstone  Energy  Holdings,  LLC,  a  subsidiary  of  the  Company  (“EEH”  and  collectively  with  Earthstone,  the  “Buyer”),
Independence  Resources  Holdings,  LLC  (“Independence”),  and  Independence  Resources  Manager,  LLC  (“Independence  Manager”  and  collectively  with
Independence,  the  “Seller”)  consummated  the  transactions  contemplated  in  the  Purchase  and  Sale  Agreement  dated  December  17,  2020  (the  “Purchase
Agreement”) that was previously reported on Form 8-K. The Seller was unaffiliated with the Company. At the closing of the Purchase Agreement, among other
things,  EEH  acquired  (the  “IRM  Acquisition”)  all  of  the  issued  and  outstanding  limited  liability  company  interests  in  certain  wholly  owned  subsidiaries  of
Independence and Independence Manager (collectively, the “Acquired Entities”) for aggregate consideration consisting of the following: (i) an aggregate amount
of cash from EEH equal to approximately $131.2 million (the “Cash Consideration”) and (ii) 12,719,594 shares of the Company’s Class A common stock, $0.001
par value per share (“Class A Common Stock”), issued to Independence (such shares, the “Acquisition Shares,” and such issuance, the “Stock Issuance”). As a
result of the Stock Issuance, Earthstone is no longer considered a controlled company within the meaning of the NYSE rules.

Amendment to Credit Agreement - In preparation for the IRM Acquisition, on December 17, 2020, Earthstone, EEH, as Borrower, Wells Fargo Bank, National
Association (“Wells Fargo”), as Administrative Agent, the guarantors party thereto, and the lenders party thereto (the “Lenders”) entered into an amendment (the
“Amendment”) to the credit agreement dated November 21, 2019, by and among EEH, as Borrower, Earthstone, as Parent, Wells Fargo, as Administrative Agent
and Issuing Bank, BOKF, NA dba Bank of Texas, as Issuing Bank with respect to Existing Letters of Credit, Royal Bank of Canada, as Syndication Agent, Truist
Bank, as successor by merger to SunTrust Bank, as Documentation Agent, and the Lenders party thereto (together with all amendments or other modifications, the
“Credit Agreement”). The Amendment was effective upon the closing of the IRM Acquisition on January 7, 2021. Among other things, the Amendment (i) joined
certain  financial  institutions  as  additional  lenders,  increased  the  borrowing  base  from  $240.0  million  to  $360.0  million,  (ii)  increased  the  interest  rate  on
outstanding borrowings; and (iii) adjusted some of the financial covenants.

Registration  Rights  Agreement -  On  January  7,  2021,  in  connection  with  the  closing  of  the  Purchase  Agreement,  Earthstone  and  Independence  entered  into  a
registration  rights  agreement  (the  “Registration  Rights  Agreement”)  relating  to  the  IRM  Acquisition  Shares  and  the  shares  of  Class  A  Common  Stock  that
Independence acquired from EnCap Investments L.P. and its affiliates (“EnCap”) on January 7, 2021 (collectively, the “Registrable Securities”). The Registration
Rights Agreement  provides  that  Earthstone  will file  a registration  statement  to permit  the public  resale  of the Registrable  Securities.  Earthstone  shall cause  the
registration statement to be continuously effective from its effective date until all of the Registrable Securities have been disposed of in the manner set forth in the
registration statement or under Rule 144 of the Securities Act, until the distribution of the Class A Common Stock does not require registration under the Securities
Act, or until there are no longer any Registrable Securities outstanding.

Voting Agreement - On January 7, 2021, in connection with the closing of the Purchase Agreement, Warburg Pincus Private Equity (E&P) XI – A, L.P. (“WPXI-
A”), Warburg Pincus XI (E&P) Partners – A, L.P. (“WPPXI”), WP IRH Holdings, L.P. (“WPIRH”), Warburg Pincus XI (E&P) Partners – B IRH, LLC (“WPXI-

WPPXI,  WPIRH,  WPXI-B,  WPE-A,  WPEP-A,  WPEP-B  and  WPEPIRH,  the  “Warburg  Parties”),  EnCap  and  Earthstone  entered  into  a  voting  agreement  (the
“Voting Agreement”) containing provisions by which the Warburg Parties will have the right to appoint one director to the Board of Directors (the “Board”) of
Earthstone. The Warburg Parties’ right to appoint one director will terminate when the Warburg Parties, in the aggregate, no longer own: (i) 8% of the outstanding
Class A Common Stock; or (ii) 10% or more of the outstanding Class A Common Stock as a result of a sale by the

8

Warburg  Parties.  The  Warburg  Parties  nominated  David  S.  Habachy  and  the  Board  appointed  Mr.  Habachy  as  a  Class  II  director  who  will  hold  office  until
Earthstone’s annual meeting of stockholders in 2023.

Lock-Up Agreement - In connection with the closing of the Purchase Agreement, on January 7, 2021, Earthstone entered into a Lock-up Agreement (the “Lock-up
Agreement”) with the Warburg Parties, pursuant to which the Warburg Parties are restricted for a period of 120 days (the “Lock-up Period”) after January 7, 2021

With  407  potential  gross  horizontal  drilling  locations  (262  operated  /  145  non-operated)  in  the  Midland  Basin  as  of  December  31,  2020,  we  are  focused  on
developmental drilling and completion operations in the area. As a result of the IRM Acquisition, we added 43,400 additional net acres with 750 gross / 738.5 net
operated producing wells and 2 gross / 1.0 net non-operated wells. The acquisition includes 4,900 net core acres located in Midland and Ector counties with 70
additional gross drilling locations. The remaining acreage is located primarily in Irion and Sterling Counties.

We continue to pursue acreage trades or bolt-on acreage acquisitions in the Midland Basin with the intent of increasing our operated acreage and drilling inventory,
drilling and completing longer laterals and realizing greater operating efficiencies.

As of December 31, 2020, we had approximately 27,900 net acres in the core of the Midland Basin that are highly contiguous on a project-by-project basis which
allow us to drill multi-well pads. Of this acreage, 78% is operated and 22% is non-operated. We hold an approximate 93% working interest in our operated acreage
and  an  approximate  40%  working  interest  in  our  non-operated  acreage.  Our  operated  acreage  in  the  Midland  Basin  is  primarily  located  in  Reagan,  Upton  and
Midland counties which includes 88 gross / 77.3 net producing wells. Our non-operated acreage in the Midland Basin is located primarily in Howard, Glasscock,
Martin, Midland and Reagan counties which includes 140 gross / 48.4 net producing wells.

As of December 31, 2020, we had approximately 12,500 net leasehold acres in the Eagle Ford Trend, primarily in the crude oil window in Fayette, Gonzales and
Karnes counties which include 115 gross / 51.4 net operated producing wells and 6 gross / 1.1 net non-operated wells.

As operator, we manage and are able to directly influence development and production of our operated properties. Independent contractors engaged by us provide
all the equipment and personnel associated with drilling and completion activities. We employ petroleum engineers, geologists and land professionals who work on
improving  operating  cost,  production  rates  and  reserves.  Our  producing  properties  have  reasonably  predictable  production  profiles  and  cash  flows,  subject  to
commodity  price  and  cost  fluctuations.  Our  status  as  an  operator  has  allowed  us  to  pursue  the  development  of  undeveloped  acreage,  further  develop  existing
properties and generate new projects.

As  is  common  in  our  industry,  we  selectively  participate  in  drilling  and  developmental  activities  in  non-operated  properties.  Decisions  to  participate  in  non-
operated properties are dependent upon the technical and economic nature of the projects and the operating expertise and financial standing of the operators.

As of December 31, 2020, our estimated proved oil and natural gas reserves were approximately 78,875 MBOE based on the reserve report prepared by Cawley,
Gillespie & Associates, Inc. (“CG&A”), our independent petroleum engineers. Based on this report, at December 31, 2020, our estimated proved reserve quantities
were approximately 51% oil, 24% natural gas and 26% NGLs with 49% of those reserves classified as proved developed.

As a result of the IRM Acquisition, we added an estimated 16,300 MBoe of proved developed producing reserves which were approximately 60% oil, 18% natural
gas and 23% NGLs.

Our Business Strategy

We  believe  that  the  current  industry  environment  will  result  in  more  consolidations;  however,  execution  may  be  hampered  by  the  high  debt  levels  of  many
producers. We continue to pursue value-accretive and scale-enhancing consolidation opportunities, as we believe we are in a position to operate effectively despite
the volatility in commodity prices experienced over the past several years. We are focusing our attention on acquisition and corporate merger opportunities that
would increase the scale of our operations, without materially altering our debt metrics in relation to our cash flows and capital. In addition, we believe the current
industry environment presents unique opportunities to acquire distressed assets or corporations that will be financially distressed in the near future which should
provide us the potential for further consolidation based on our financial strength. At the same time, we will seek to block up acreage in the Midland Basin that
would allow for longer horizontal laterals and should

9

therefore provide for higher economic returns. In summary, we believe we are well qualified to be a consolidator which would increase the scale of our operations
and add value to our shareholders.

Our current business strategy is to focus on the economic development of our existing acreage, increase our acreage and horizontal well locations in the Midland
Basin and increase stockholder value through the following:

•

•

•

•

•

•

•

•

•

•

developing  our  acreage  and  profitably  growing  our  production  while  seeking  to  achieve  Free  Cash  Flow  (defined  in  “Non-GAAP  Measures”
below);

operating our properties efficiently and continuing to improve our operating margins;

deploying capital efficiently by drilling multi-well pads, reducing drilling times and increasing completions per day;

operating our assets in a safe and environmentally sensitive manner;

continuing to hedge commodity prices as opportunities arise;

pursuing value-accretive acquisition and corporate merger opportunities, which could increase the scale of our operations;

maximizing operating margins and corporate level cash flows by minimizing operating and overhead costs;

expanding our acreage positions and drilling inventory in our primary areas of interest through acquisitions and farm-in opportunities, with an
emphasis on operated positions;

blocking up acreage to allow for longer horizontal lateral drilling locations which provide higher economic returns; and

maintaining a strong balance sheet and financial flexibility.

Commodity Price Recovery

10

As oil prices have recovered recently from their 2020 lows, we are preparing to resume drilling operations with the deployment of a rig late in the first quarter of
2021 and we expect to spend $90-$100 million in total capital expenditures during 2021 based on our current 2021 capital spending plan.

Officer Appointments

Effective April 1, 2020, our former Chairman and Chief Executive Officer, Mr. Frank A. Lodzinski, was appointed Executive Chairman and our President, Mr.
Robert J. Anderson, was appointed President and Chief Executive Officer.

COVID-19

Despite  the  recent  recoveries  in  commodity  prices,  the  COVID-19  pandemic  has  negatively  impacted  the  global  economy,  disrupted  global  supply  chains  and
created significant volatility and disruption of financial and commodity markets. In addition, the pandemic has resulted in travel restrictions, business closures and
the institution of quarantining and other restrictions on movement in many communities. As a result, there has been significant volatility in demand for and prices
of oil and natural  gas. The extent  of the  impact  of the COVID-19 pandemic  on our operational  and financial  performance,  including  our ability  to execute  our
business  strategies  and  initiatives  in  the  expected  time  frame,  is  uncertain  and  depends  on  various  factors,  including  how  the  pandemic  and  measures  taken  in
response to its impact on demand for oil and natural gas, the availability of personnel, equipment and services critical to our ability to operate our properties and
the impact of potential governmental restrictions on travel, transports and operations. There is uncertainty around the extent and duration of disruption, including
any resurgence, and we expect that the longer the duration of any such disruption, the greater the adverse impact may be on our business. The degree to which the
COVID-19 pandemic or any other public health crisis adversely impacts our results will depend on future developments, which are highly uncertain and cannot be
predicted, including, but not limited to, the duration and spread of the pandemic, its severity, the actions to contain the virus or treat its impact, its impact on the
U.S. and world economies, the U.S. capital markets and market conditions, and how quickly and to what extent normal economic and operating conditions can
resume.

Operational Status

As a producer of oil, natural gas and NGLs, we are recognized as an essential business under various federal, state and local regulations related to the COVID-19
pandemic.  We  have  continued  to  operate  as  permitted  under  these  regulations  while  taking  mitigation  efforts  and  steps  to  protect  the  health  and  safety  of  our
employees. The safety of our employees is paramount, and we have emphasized the respective guidelines to support our mitigation efforts. Our field personnel are
performing  their  job  responsibilities  and  practicing  mitigation  guidelines  with  no  issues  to  date.  Our  non-field  personnel  had  been  working  remotely,  using
information technology in which we previously invested. More recently, the majority of our non-field personal have been working at our corporate offices while
adhering to local county and CDC guidelines. Upon returning to work at our corporate offices, we implemented protocols that consist of required mask wearing
zones, use of installed sanitization equipment in various locations and practice social distancing in gathering areas such as conference rooms. We have managed
and conducted both field and non-field functions effectively thus far, including our day-to-day operations, our accounting and financial reporting systems and our
internal  control  over  financial  reporting.  We  will  continue  to  focus  on  the  health  and  safety  of  our  employees  in  conformity  with  the  applicable  jurisdictional
mitigation guidelines.

Commodity Market Challenges

The significant decline in commodity prices resulting from the COVID-19 pandemic negatively impacted producers of oil, natural gas and NGLs in the U.S. and
elsewhere. The COVID-19 pandemic resulted in global consumer demand contraction and the ensuing supply/demand imbalance has had a disruptive impact on oil
and gas exploration and production. In April 2020, WTI crude oil prices averaged $16.55/Bbl and briefly fell below $0/Bbl, closing at -$36.98/Bbl on April 20,
2020. In response, management began to voluntarily shut-in as much production as was feasible in an effort to preserve reserves to sell in the future. As prices
returned to economic levels, management returned those wells to production as quickly as possible, beginning in late May and early June. Management estimates
that total net production was curtailed by approximately 60% in May, with minimal volumes curtailed in April and June. Since June 2020, we have returned to
operating  at  full  production  capacity  as  oil  prices  have  continued  to  recover.  Additionally,  based  on  the  current  recovered  commodity  price  levels,  we  plan  to
commence a drilling program late in the first quarter of 2021.

Operational/Financial Challenges

It is difficult to model and predict how our operations and financial status may change as a result of COVID-19. In our industry, any forecast, plans and changes to
operations and financial status are a function of commodity prices. If oil prices decline due to a resurgence of COVID-19, we believe we can continue to operate
and produce our properties at a minimum in a cash flow neutral position for the next 12 months. We will have to manage the possibility of well shut-ins, both
voluntary and involuntary,

11

to preserve our assets and cash flows. A significant driver in the future may be the financial institutions’ view on commodity prices with respect to borrowing base
redeterminations. If a resurgence of COVID-19 triggers additional volatility in our business or global economies, our borrowing base, currently set at $360 million,
could be reduced. Significant reductions in the borrowing base under our Credit Agreement could create a borrowing base deficiency depending on or loans then
outstanding which may lead to a default. We believe global, as well as national, mitigation efforts currently being implemented to fight COVID-19 have had, and
may continue to have, a material impact on commodity prices and may continue to present significant challenges to our industry.

The effects of COVID-19, including a substantial decrease in economic activity, have contributed to significant credit, debt and equity market volatility. Similar to
other producers in our business, we experienced volatility in the price of our Class A common stock.

Government Assistance

Although management explored all assistance available under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), the Company was not
eligible for any of the programs therein with the exception of the deferral of employment tax deposits and payments which management has currently not elected to
pursue.

Employee Reduction Measures

In June 2020, management completed a workforce reduction effort that reduced the number of full-time employees from 68 to 60 by month end, resulting in over a
10% decrease in aggregate salaries and wages. Severance related costs associated with these reduction measures resulted in operating expenses of $0.4 million in
June  2020.  At  this  time,  management  has  no  future  plans  for  further  workforce  reductions;  however,  if  adverse  industry  conditions  occur,  further  employee
reduction measures may be necessary.

Organizational Structure

Earthstone is the sole managing member of EEH, with a controlling interest in EEH. Earthstone, together with its wholly-owned subsidiary, Lynden Energy Corp.,
a  corporation  organized  under  the  laws  of  British  Columbia  (“Lynden  Corp”),  and  Lynden  Corp’s  wholly-owned  consolidated  subsidiary,  Lynden  USA,  Inc.
(“Lynden US”) and also a member of EEH, consolidates the financial results of EEH and records a noncontrolling interest in the Consolidated Financial Statements
representing  the  economic  interests  of  EEH’s  members  other  than  Earthstone  and  Lynden  US.  Additionally,  on  January  7,  2021,  upon  closing  of  the  IRM
Acquisition, IRM became a wholly owned subsidiary of EEH.

Operational Risks

Oil  and  natural  gas  exploitation,  development  and  production  involve  a  high  degree  of  risk,  which  even  a  combination  of  experience,  knowledge  and  careful
evaluation may not be able to overcome. There is no assurance that we will acquire, discover or produce additional oil and natural gas in commercial quantities. Oil
and natural gas operations also involve the risk that well fires, blowouts, equipment failure, human error and other events may cause accidental leakage or spills of
toxic or hazardous materials,  such as petroleum  liquids or drilling  fluids into the environment  or cause significant  injury to persons or property. In such event,
substantial liabilities to third parties or governmental entities may be incurred, the satisfaction of which could substantially reduce our available cash and possibly
result  in  loss  of  oil  and  natural  gas  properties.  Such  hazards  may  also  cause  damage  to  or  destruction  of  wells,  producing  formations,  production  facilities  and
pipeline or other processing facilities.

As is common in the oil and natural gas industry, we do not insure fully against all risks associated with our business either because such insurance is not available
or because we believe the premium costs are prohibitive. A loss not fully covered by

12

insurance could have a material effect on our operating results, financial position and cash flows. For further discussion of these risks see Item 1A. Risk Factors of
this report.

Marketing and Customers

We market the majority of the production from properties we operate for both our account and the account of the other working interest owners in these properties.
We sell our production to purchasers at market prices.

We  normally  sell  production  to  a relatively  small  number  of customers,  as  is  customary  in  the  exploration,  development  and  production  business.  For the  year
ended December 31, 2020, three purchasers accounted for 32%, 15% and 12%, respectively, of our revenue during the period. For the year ended December 31,
2019, three purchasers accounted for 30%, 14% and 12%, respectively, of our revenue during the period. No other customer accounted for more than 10% of our
revenue during these periods. If a major customer stopped purchasing oil and natural gas from us, revenue could decline and our operating results and financial
condition could be harmed. However, we believe that the loss of any one or all of our major purchasers would not have a materially adverse effect on our financial
condition or results of operations, as crude oil and natural gas are fungible products with well-established markets and numerous purchasers.

Transportation

During the planning stage of our prospective and productive units and acreage, we consider required flow-lines, gathering and delivery infrastructure. Our oil is
transported from the wellhead to our tank batteries or delivery points through our flow-lines or gathering systems. Purchasers of our oil take delivery at (i) our tank
batteries and transport the oil by truck, or (ii) at a pipeline delivery point. Our natural gas is transported from the wellhead to the purchaser’s meter and pipeline
interconnection  point  through  our  gathering  systems.  We  have  implemented  a  Leak  Detection  and  Repair  program,  or  LDAR,  to  locate  and  repair  leaking
components  including  valves,  pumps  and connectors  in order  to minimize  the  emission  of fugitive  volatile  organic  compounds and  hazardous  air  pollutants.  In
addition, we install vapor recovery units in our newer tank batteries which also reduces emissions.

We are party to a buy/sell arrangement for a certain portion of our oil production that effects a change in location with required repurchase of oil at a delivery
point.  This  activity  is  recorded  on  a  net  basis  and  the  residual  transportation  fee  is  included  in  Lease  operating  expenses  in  the  Consolidated  Statements  of
Operations. Arrangements such as this not only reduce our transportation costs by eliminating truck transportation but also provide additional flexibility in delivery
points for our product. The decrease in transportation by truck also translates into reduced truck emissions.

Our produced salt water is generally moved by pipeline connected to our operated salt water disposal wells or by pipeline to commercial disposal facilities.

Commodity Hedging

Consistent with our disciplined approach to financial management, we have an active commodity hedging program through which we seek to hedge a meaningful
portion of our expected oil and gas production, reducing our exposure to downside commodity prices and enabling us to protect cash flows and maintain liquidity
to fund our capital program.

Competition

The domestic oil and natural gas industry is intensely competitive in the acquisition of acreage, production and oil and gas reserves and in producing, transporting
and marketing activities. Our competitors include national oil companies, major oil and natural gas companies, independent oil and natural gas companies, drilling
partnership programs, individual producers, natural gas marketers, and major pipeline companies, as well as participants in other industries supplying energy and
fuel to consumers. Many of our competitors are large, well-established companies. They may be able to pay more for seismic information and lease rights on oil
and natural gas properties and to define, evaluate, bid for and purchase a greater number of properties, than our financial or human resources permit. Our ability to
acquire  additional  properties  in  the  future,  and  our  ability  to  fund  the  acquisition  of  such  properties,  will  be  dependent  upon  our  ability  to  evaluate  and  select
suitable properties and to consummate related transactions in a highly competitive environment.

There  is  also  competition  between  oil  and  natural  gas  producers  and  other  industries  producing  energy  and  fuel.  Furthermore,  competitive  conditions  may  be
substantially  affected  by  various  forms  of  energy  legislation  and/or  regulation  considered  from  time  to  time  by  the  governments  of  the  United  States  and  the
jurisdictions in which we operate. It is not possible to predict the nature of any such legislation or regulation which may ultimately be adopted or its effects upon
our future operations. Such laws and regulations may substantially increase the costs of exploring for, developing or producing oil and natural gas and may prevent
or delay the commencement or continuation of a given operation. Our larger competitors may be able to absorb the burden of existing and any changes to, federal,
state and local laws and regulations more easily than we can, which would adversely affect our competitive position.

13

Segment Information and Geographic Area

Operating segments are defined under accounting principles generally accepted in the United States (“GAAP”) as components of an enterprise that (i) engage in
activities from which it may earn revenues and incur expenses (ii) for which separate operational financial information is available and is regularly evaluated by
the chief operating decision maker for the purpose of allocating resources and assessing performance.

Based on our organization and management, we have only one reportable operating segment, which is oil and natural gas acquisition, exploration, development and
production. All of our operations are currently conducted in Texas.

Seasonality of Business

Weather conditions often affect the demand for, and prices of, natural gas and can also delay oil and natural gas drilling, completion and production activities,
disrupting  our  overall  business  plans.  Demand  for  natural  gas  is  typically  higher  during  the  winter,  resulting  in  higher  natural  gas  prices  for  our  natural  gas
production  during  our  first  and  fourth  fiscal  quarters.  Due  to  these  seasonal  fluctuations,  our  results  of  operations  for  individual  quarterly  periods  may  not  be
indicative of the results that we may realize on an annual basis.

Markets for Sale of Production

Our ability to market oil and natural gas found and produced, depends on numerous factors beyond our control, the effect of which cannot be accurately predicted
or anticipated. Some of these factors include, without limitation, the availability of other domestic and foreign production, the marketing of competitive fuels, the
proximity and capacity of pipelines, fluctuations in supply and demand, the availability of a ready market, the effect of United States federal and state regulation of
production,  refining,  transportation  and  sales  and  general  national  and  worldwide  economic  conditions.  Additionally,  we  may  experience  delays  in  marketing
natural gas production and fluctuations in natural gas prices and we may experience short-term delays in marketing oil due to trucking and refining constraints.
There  is  no  assurance  that  we  will  be  able  to  market  any  oil  or  natural  gas  produced,  or,  if  such  oil  or  natural  gas  is  marketed,  that  favorable  prices  can  be
obtained.  

The United States natural gas market has undergone several significant changes over the past few decades. The majority of federal price ceilings were removed in
1985 and the remainder were lifted by the Natural Gas Wellhead Decontrol Act of 1989. Thus, currently, the United States natural gas market is operating in a free
market environment in which the price of gas is determined by market forces rather than by regulations. At the same time, the domestic natural gas industry has
also seen a dramatic change in the manner in which gas is bought, sold and transported. In most cases, natural gas is no longer sold to a pipeline company. Instead,
the pipeline company now primarily serves the role of transporter and gas producers are free to sell their product to marketers, local distribution companies, end
users or a combination thereof.

In  recent  years,  oil,  natural  gas  and  NGLs  prices  have  been  under  considerable  pressure  due  to  oversupply  and  other  market  conditions,  including  constrained
pipeline  capacity.  Specifically,  increased  domestic  and  foreign  production  and  increased  efficiencies  in  horizontal  drilling  and  completion,  combined  with
increased development of shale fields in North America, have dramatically increased global oil and natural gas production, which has led to significantly lower
market prices for these commodities. In view of the many uncertainties affecting the supply and demand for oil, natural gas and NGLs, we are unable to accurately
predict future oil, natural gas and NGLs prices or the overall effect, if any, that the decline in demand for and the oversupply of such products will have on our
financial condition or results of operations.

Title to Properties

We believe  that the title  to our oil and natural  gas properties  is good and defensible  in accordance  with standards generally  accepted  in the oil and natural  gas
industry, subject to such exceptions which, in our opinion, are not so material as to detract substantially from the use or value of our oil and natural gas properties.
Our oil and natural gas properties are typically subject, in one degree or another, to one or more of the following:

•

•

•

•

•

royalties and other burdens and obligations, express or implied, under oil and natural gas leases;

overriding royalties and other burdens created by us or our predecessors in title;

a variety of contractual obligations (including, in some cases, development obligations) arising under operating agreements, farmout agreements,
participation agreements, production sales contracts and other agreements that may affect the properties or their titles;

back-ins and reversionary interests existing under various agreements and leasehold assignments;

liens that arise in the normal course of operations, such as those for unpaid taxes, statutory liens securing obligations to unpaid suppliers and
contractors and contractual liens under operating agreements;

14

•

•

pooling, unitization and other agreements, declarations and orders; and

easements, restrictions, rights-of-way and other matters that commonly affect property.

To the extent that such burdens and obligations affect our rights to production revenues, they have been taken into account in calculating our net revenue interests
and in estimating the quantity and value of our reserves. We believe that the burdens and obligations affecting our oil and natural gas properties are common in our
industry with respect to the types of properties we own.

Operational Regulations

All of the jurisdictions in which we own or operate producing oil and natural gas properties have statutory and regulatory provisions affecting drilling, completion,
and production activities, including, but not limited to, provisions related to permits for the drilling of wells, bonding requirements to drill or operate wells, the
location of wells, the method of drilling and casing wells, the surface use and restoration of properties upon which wells are drilled, sourcing and disposal of water
used  in  the  drilling  and  completion  process,  and  the  plugging  and  abandonment  of  wells.  Our  operations  are  also  subject  to  various  conservation  laws  and
regulations. These laws and regulations govern the size of drilling and spacing units, the density of wells that may be drilled in oil and natural gas properties and
the unitization or pooling of oil and natural gas properties. In this regard, while some states allow the forced pooling or integration of land and leases to facilitate
development, other states including Texas, where we operate, rely primarily or exclusively on voluntary pooling of land and leases. Accordingly, it may be difficult
for us to form spacing units and therefore difficult to develop a project if we own or control less than 100% of the leasehold. In addition, state conservation laws
establish maximum rates of production from oil and natural gas wells, generally prohibit the venting or flaring of natural gas, and impose specified requirements
regarding  the  ratability  of  production.  On  some  occasions,  local  authorities  have  imposed  moratoria  or  other  restrictions  on  exploration,  development  and
production  activities  pending  investigations  and  studies  addressing  potential  local  impacts  of  these  activities  before  allowing  oil  and  natural  gas  exploration,
development and production to proceed.

The effect of these regulations is to limit the amount of oil and natural gas that we can produce from our wells and to limit the number of wells or the locations at
which we can drill, although we can apply for exceptions to such regulations or to have reductions in well spacing. Failure to comply with applicable laws and
regulations can result in substantial penalties. The regulatory burden on the industry increases the cost of doing business and affects profitability. Moreover, each
state generally imposes a production or severance tax with respect to the production and sale of oil, natural gas and natural gas liquids within its jurisdiction.

Regulation of Transportation of Natural Gas

The  transportation  and  sale,  or  resale,  of  natural  gas  in  interstate  commerce  are  regulated  by  the  Federal  Energy  Regulatory  Commission  (“FERC”)  under  the
Natural Gas Act of 1938 (“NGA”), the Natural Gas Policy Act of 1978 (“NGPA”) and regulations issued under those statutes. FERC regulates interstate natural
gas  transportation  rates  and service  conditions,  which  affects  the  marketing  of  natural  gas  that  we produce,  as well  as  the  revenues  we receive  for  sales  of  our
natural gas.

Intrastate natural gas transportation is also subject to regulation by state regulatory agencies. 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. Insofar as such regulation within a
particular state will generally affect all intrastate natural gas shippers within the state on a comparable basis, we believe that the regulation of similarly situated
intrastate natural gas transportation in any states in which we operate and ship natural gas on an intrastate basis will not affect our operations in any way that is of
material difference from those of our competitors. Like the regulation of interstate transportation rates, the regulation of intrastate transportation rates affects the
marketing of natural gas that we produce, as well as the revenues we receive for sales of our natural gas.

Regulation of Sales of Oil, Natural Gas and Natural Gas Liquids

The prices at which we sell oil, natural gas and natural gas liquids are not currently subject to federal regulation and, for the most part, are not subject to state
regulation. FERC, however, regulates interstate natural gas transportation rates, and terms and conditions of transportation service, which affects the marketing of
the natural gas we produce, as well as the prices we receive for sales of our natural gas. Similarly, the price we receive from the sale of oil and natural gas liquids is
affected by the cost of transporting those products to market.  FERC regulates the transportation of oil and liquids on interstate pipelines under the provision of the
Interstate Commerce Act, the Energy Policy Act of 1992 and regulations issued under those statutes.  Intrastate transportation of oil, natural gas liquids, and other
products, is dependent on pipelines whose rates, terms and conditions of service are subject to regulation by state regulatory bodies under state statutes. In addition,
while sales by producers of natural gas and all sales of crude oil, condensate, and natural gas liquids can currently be made at uncontrolled market prices, Congress
could reenact price controls in the future. 

15

Changes in FERC or state policies and regulations or laws may adversely affect the availability and reliability of firm and/or interruptible transportation service on
interstate  pipelines,  and  we  cannot  predict  what  future  action  that  FERC  or  state  regulatory  bodies  will  take.  We  do  not  believe,  however,  that  any  regulatory
changes will affect us in a way that materially differs from the way they will affect other natural gas producers, gatherers and marketers with which we compete.

Our operations are also subject to stringent federal, state and local laws regulating the discharge of materials into the environment or otherwise relating to health
and safety or the protection of the environment. Numerous governmental agencies, such as the United States Environmental Protection Agency (the “EPA”) issue
regulations  to  implement  and  enforce  these  laws,  which  often  require  difficult  and  costly  compliance  measures.  Among  other  things,  environmental  regulatory
programs  typically  govern  the  permitting,  construction  and  operation  of  a  well  or  production  related  facility.  Many  factors,  including  public  perception,  can
materially impact the ability to secure an environmental construction or operation permit. Failure to comply with environmental laws and regulations may result in
the assessment of substantial administrative, civil and criminal penalties, as well as the issuance of injunctions limiting or prohibiting our activities. In addition,
some laws and regulations relating to protection of the environment may, in certain circumstances, impose strict liability for environmental contamination, which
could result in liability for environmental damages and cleanup costs without regard to negligence or fault on our part.

Beyond existing requirements, new programs and changes in existing programs, may affect our business including oil and natural gas exploration and production,
air emissions, waste management, and underground injection of waste material. Environmental laws and regulations have been subject to frequent changes over the
years, and the imposition of more stringent requirements could have a material adverse effect on our financial condition and results of operations. The following is
a  summary  of  the  more  significant  existing  environmental,  health  and  safety  laws  and  regulations  to  which  our  business  operations  are  subject  and  for  which
compliance in the future may have a material adverse impact on our capital expenditures, earnings and competitive position.

Hazardous Substances and Wastes

The federal Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (“CERCLA”), also known as the Superfund law, and comparable
state laws impose liability, without regard to fault or the legality of the original conduct on certain categories of persons that are considered to be responsible for
the release of a hazardous substance into the environment. These persons may include the current or former owner or operator of the site or sites where the release
occurred and companies that disposed or arranged for the disposal of hazardous substances found at the site. Under CERCLA, these potentially responsible persons
may be subject to strict, joint and several liability for the costs of investigating and cleaning up hazardous substances that have been released into the environment,
for damages to natural resources and for the costs of certain health studies. 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 or other pollutants released into the environment. We are able to
control directly the operation of only those wells with respect to which we act as operator. Notwithstanding our lack of direct control over wells operated by others,
the  failure  of  an  operator  other  than  us  to  comply  with  applicable  environmental  regulations  may,  in  certain  circumstances,  be  attributed  to  us.  We  generate
materials in the course of our operations that may be regulated as hazardous substances but we are not presently aware of any liabilities for which we may be held
responsible that would materially or adversely affect us.

The  Resource  Conservation  and  Recovery  Act  of  1976  (“RCRA”),  and  comparable  state  statutes,  regulate  the  generation,  treatment,  storage,  transportation,
disposal  and  clean-up  of  hazardous  and  solid  (non-hazardous)  wastes.  With  the  approval  of  the  EPA,  the  individual  states  can  administer  some  or  all  of  the
provisions  of  RCRA,  and  some  states  have  adopted  their  own,  more  stringent  requirements.  Drilling  fluids,  produced  waters  and  most  of  the  other  wastes
associated with the exploration, development and production of oil and natural gas are currently regulated under RCRA’s solid (non-hazardous) waste provisions.
However,  legislation  has  been  proposed  from  time  to  time  and  various  environmental  groups  have  filed  lawsuits  that,  if  successful,  could  result  in  the
reclassification  of  certain  oil  and  natural  gas  exploration  and  production  wastes  as  “hazardous  wastes,”  which  would  make  such  wastes  subject  to  much  more
stringent handling, disposal and clean-up requirements. A loss of the RCRA exclusion for drilling fluids, produced waters and related wastes could result in an
increase in our, as well as the oil and natural gas E&P industry’s, costs to manage and dispose of generated wastes, which could have a material adverse effect on
the industry as well as on our business.

From time to time, releases of materials or wastes have occurred at locations we own or at which we have operations. These properties and the materials or wastes
released thereon may be subject to CERCLA, RCRA and analogous state laws. Under these laws, we have been and may be required to remove or remediate such
materials or wastes.

Water Discharges

16

The federal Clean Water Act and analogous state laws impose restrictions and strict controls with respect to the discharge of pollutants, including spills and leaks
of  oil  and  other  substances,  into  waters  of  the  United  States.  The  discharge  of  pollutants  into  regulated  waters,  including  jurisdictional  wetlands,  is  prohibited,
except in accordance with the terms of a permit issued by the EPA or an analogous state agency. In September 2015, the EPA and U.S. Army Corps of Engineers
(the “Corps”) rule defining the scope of federal jurisdiction over Waters of the United States (the “WOTUS rule”) became effective. Following the change in U.S.
Presidential Administrations, there have been several attempts to modify or eliminate this rule. For example, on January 23, 2020, the EPA and the Corps finalized
the Navigable Waters Protection Rule, which narrows the definition of “waters of the United States” relative to the prior 2015 rulemaking. However, both this and
prior rulemakings regarding the definition of WOTUS are currently subject to litigation, and it is possible that the Biden Administration could propose a broader
interpretation of the Clean Water Act’s applicability. As a result of these developments, the scope of jurisdiction under the Clean Water Act is uncertain at this
time.

The  process  for  obtaining  permits  has  the  potential  to  delay  our  operations.  Spill  prevention,  control  and  countermeasure  requirements  of  federal  laws  require
appropriate containment berms and similar structures to help prevent the contamination of navigable waters by a petroleum hydrocarbon tank spill, rupture or leak.
In addition, the Clean Water Act and analogous state laws require individual permits or coverage under general permits for discharges of storm water runoff from
certain types of facilities. Federal and state regulatory agencies can impose administrative, civil and criminal penalties as well as other enforcement mechanisms
for  non-compliance  with  discharge  permits  or  other  requirements  of  the  Clean  Water  Act  and  analogous  state  laws  and  regulations.  The  Clean  Water  Act  and
analogous state laws provide for administrative, civil and criminal penalties for unauthorized discharges and, together with the Oil Pollution Act of 1990 (“OPA”),
impose  rigorous  requirements  for  spill  prevention  and  response  planning,  as  well  as  substantial  potential  liability  for  the  costs  of  removal,  remediation,  and
damages in connection with any unauthorized discharges.

Our  oil  and  natural  gas  production  also  generates  salt  water,  which  we  dispose  of  by  underground  injection.  The  federal  Safe  Drinking  Water  Act  (“SDWA”)
regulates the underground injection of substances through the Underground Injection Control (“UIC”) program, and related state programs regulate the drilling and
operation of salt water disposal wells. The EPA directly administers the UIC program in some states, and in others it is delegated to the state for administering. In
Texas, the Texas Railroad Commission (“RRC”) regulates the disposal of produced water by injection well.  Permits must be obtained before drilling salt water
disposal  wells,  and  casing  integrity  monitoring  must  be  conducted  periodically  to  ensure  the  casing  is  not  leaking  salt  water  to  groundwater.  Contamination  of
groundwater by oil and natural gas drilling, production, and related  operations may result in fines, penalties, and remediation  costs, among other sanctions and
liabilities under the SDWA and state laws. In response to recent seismic events near underground injection wells used for the disposal of oil and natural gas-related
waste waters, federal and some state agencies have begun investigating whether such wells have caused increased seismic activity, and some states have shut down
or  placed  volumetric  injection  limits  on  existing  wells  or  imposed  moratoria  on  the  use  of  such  injection  wells.  In  response  to  concerns  related  to  induced
seismicity, regulators in some states have already adopted or are considering additional requirements related to seismic safety. For example, the RRC has adopted
rules for injection wells to address these seismic activity concerns in Texas. Among other things, the rules require companies seeking permits for disposal wells to
provide seismic activity data in permit applications, provide for more frequent monitoring and reporting for certain wells and allow the RRC to modify, suspend, or
terminate permits on grounds that a disposal well is likely to be, or determined to be, causing seismic activity. More stringent regulation of injection wells could
lead  to  reduced  construction  or  the  capacity  of  such  wells,  which  could  in  turn  impact  the  availability  of  injection  wells  for  disposal  of  wastewater  from  our
operations.  Increased  costs  associated  with  the  transportation  and  disposal  of  produced  water,  including  the  cost  of  complying  with  regulations  concerning
produced water disposal, may reduce our profitability. The costs associated with the disposal of proposed water are commonly incurred by all oil and natural gas
producers, however, and we do not believe that these costs will have a material adverse effect on our operations. In addition, third-party claims may be filed by
landowners and other parties claiming damages for alternative water supplies, property damages, and bodily injury.

Hydraulic Fracturing

Our completion operations are subject to regulation, which may increase in the short- or long-term. In particular, the well completion technique known as hydraulic
fracturing which is used to stimulate production of oil and natural gas has come under increased scrutiny by the environmental community, and many local, state
and  federal  regulators.  Hydraulic  fracturing  involves  the  injection  of  water,  sand  and  additives  under  pressure,  usually  down  casing  that  is  cemented  in  the
wellbore, into prospective rock formations in order to stimulate oil and natural gas production. We engage third parties to provide hydraulic fracturing or other well
stimulation services to us in connection with substantially all of the wells for which we are the operator.

The SDWA regulates the underground injection of substances through the UIC program. Hydraulic fracturing is generally exempt from regulation under the UIC
program, and the hydraulic fracturing process is typically regulated by state oil and gas commissions. However, legislation has been proposed in recent sessions of
Congress to amend the SDWA to repeal the exemption for hydraulic fracturing from the definition of “underground injection,” to require federal permitting and
regulatory control of hydraulic fracturing, and to require disclosure of the chemical constituents of the fluids used in the fracturing process.

17

Furthermore, several federal agencies have asserted regulatory authority over certain aspects of the fracturing process. For example, the EPA has taken the position
that hydraulic fracturing with fluids containing diesel fuel is subject to regulation under the UIC program, specifically as “Class II” UIC wells.

In addition, on June 28, 2016, the EPA published a final rule prohibiting the discharge of wastewater from onshore unconventional oil and natural gas extraction
facilities to publicly owned wastewater treatment plants. The EPA is also conducting a study of private wastewater treatment facilities (also known as centralized
waste treatment (“CWT”) facilities) accepting oil and natural gas extraction wastewater. The EPA is collecting data and information related to the extent to which
CWT facilities  accept  such wastewater,  available  treatment  technologies (and their associated  costs), discharge  characteristics,  financial  characteristics  of CWT
facilities, and the environmental impacts of discharges from CWT facilities.

Furthermore, there are certain governmental reviews either underway or being proposed that focus on environmental aspects of hydraulic fracturing practices. On
December 13, 2016, the EPA released a study examining the potential for hydraulic fracturing activities to impact drinking water resources, finding that, under
some circumstances, the use of water in hydraulic fracturing activities can impact drinking water resources. Also, on February 6, 2015, the EPA released a report
with findings and recommendations related to public concern about induced seismic activity from disposal wells. The report recommends strategies for managing
and minimizing  the potential  for significant  injection-induced  seismic  events.  Other governmental  agencies,  including the U.S. Department  of Energy, the U.S.
Geological Survey, and the U.S. Government Accountability Office, have evaluated or are evaluating various other aspects of hydraulic fracturing. These ongoing
or proposed studies could spur initiatives to further regulate hydraulic fracturing and could ultimately make it more difficult or costly for us to perform fracturing
and increase our costs of compliance and doing business.

Several states, including Texas, have adopted or are considering adopting regulations that could restrict or prohibit hydraulic fracturing in certain circumstances,
impose more stringent operating standards and/or require the disclosure of the composition of hydraulic fracturing fluids. For example, Texas law requires that the
well operator disclose the list of chemical ingredients subject to the requirements of the federal Occupational Safety and Health Act (“OSHA”) for disclosure on
a website and also file the list of chemicals with the RRC with the well completion report. The total volume of water used to hydraulically fracture a well must also
be disclosed to the public and filed with the RRC. If new or more stringent state or local legal restrictions relating to the hydraulic fracturing process are adopted in
areas where we operate, we could incur potentially significant added costs to comply with such requirements, experience delays or curtailment in the pursuit of
exploration, development or production activities, and perhaps even be precluded from drilling wells.

There  has  been  increasing  public  controversy  regarding  hydraulic  fracturing  with  regard  to  the  use  of  fracturing  fluids,  induced  seismic  activity,  impacts  on
drinking  water  supplies,  use  of  water  and  the  potential  for  impacts  to  surface  water,  groundwater  and  the  environment  generally.  A  number  of  lawsuits  and
enforcement actions have been initiated across the country implicating hydraulic fracturing practices. If new laws or regulations that significantly restrict hydraulic
fracturing are adopted, such laws could make it more difficult or costly for us to perform fracturing to stimulate production from tight formations as well as make it
easier for third parties opposing the hydraulic fracturing process to initiate legal proceedings based on allegations that specific chemicals used in the fracturing
process could adversely affect groundwater. In addition, if hydraulic fracturing is further regulated at the federal, state or local level, our fracturing activities could
become  subject  to  additional  permitting  and  financial  assurance  requirements,  more  stringent  construction  specifications,  increased  monitoring,  reporting  and
recordkeeping  obligations,  plugging  and  abandonment  requirements  and  also  to  attendant  permitting  delays  and  potential  increases  in  costs.  Such  legislative
changes could cause us to incur substantial compliance costs, and compliance or the consequences of any failure to comply by us could have a material adverse
effect  on  our  financial  condition  and  results  of  operations.  At  this  time,  it  is  not  possible  to  estimate  the  impact  on  our  business  of  newly  enacted  or  potential
federal, state or local laws governing hydraulic fracturing.

From time to time, legislation has been introduced, but not enacted, in the U.S. Congress to provide for federal regulation of hydraulic fracturing and to require
disclosure of the chemicals used in the hydraulic fracturing process. On January 28, 2020, Senate Bill 3247 was introduced and if enacted as proposed, would ban
hydraulic fracturing nationwide by 2025.

Air Emissions

The federal Clean Air Act (“CAA”) and comparable state laws restrict emissions of various air pollutants through permitting programs and the imposition of other
requirements. In addition, the EPA has developed and continues to develop stringent regulations governing emissions of toxic air pollutants at specified sources,
including oil and natural gas production. 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. Our operations, or the operations of service companies engaged by us, may in
certain circumstances and locations be subject to permits and restrictions under these statutes for emissions of air pollutants.

18

In 2012 and 2016, the EPA issued New Source Performance Standards to regulate emissions of sources of volatile organic compounds (“VOCs”), sulfur dioxide,
air toxics and methane from various oil and natural gas exploration, production, processing and transportation facilities. In particular, on May 12, 2016, the EPA
amended its regulations to impose new standards for methane and volatile organic compounds emissions for certain new, modified, and reconstructed equipment,
processes, and activities across the oil and natural gas sector. However, in a March 28, 2017 executive order, the Trump Administration directed the EPA to review
the  2016  regulations  and,  if  appropriate,  to  initiate  a  rule  making  to  rescind  or  revise  them  consistent  with  the  stated  policy  of  promoting  clean  and  safe
development of the nation’s energy resources, while at the same time avoiding regulatory burdens that unnecessarily encumber energy production. In September
2020, the EPA finalized amendments to the 2016 standards that removed the transmission and storage segment from the oil and natural gas source category and
rescinded the methane-specific requirements for production and processing facilities. However, President Biden signed an executive order on his first day in office
calling for the suspension, revision, or rescission of the September 2020 rule and the reinstatement or issuance of methane emission standards for new, modified,
and existing oil and gas facilities. Given the long-term trend toward increasing regulation, future federal Greenhouse Gas (“GHG”) regulations of the oil and gas
industry remain a possibility, and several states have separately imposed their own regulations on methane emissions from oil and gas production activities. These
standards,  as  well  as  any  future  laws  and  their  implementing  regulations,  may  require  us  to  obtain  pre-approval  for  the  expansion  or  modification  of  existing
facilities or the construction of new facilities expected to produce air emissions, impose stringent air permit requirements, or mandate the use of specific equipment
or technologies to control emissions. We cannot predict the final regulatory requirements or the cost to comply with such requirements with any certainty.

In October 2015, the EPA announced that it was lowering the primary National Ambient Air Quality Standards (“NAAQS”) for ozone from 75 parts per billion to
70 parts per billion. Since that time, the EPA has issued area designations with respect to ground-level ozone. In December 2020, the EPA announced its intention
to leave the ozone NAAQS unchanged at 70 parts per billion rather than lower them further. However, as discussed above, that action could be subject to reversal
following the Biden Administration’s January 2021 executive order. Reclassification of areas of state implementation of the revised NAAQS could result in stricter
permitting  requirements,  delay  or  prohibit  our  ability  to  obtain  such  permits,  and  result  in  increased  expenditures  for  pollution  control  equipment,  the  costs  of
which could be significant.

While the State of Texas has not formally conducted a recent rulemaking related to air emissions, scrutiny of oil and natural gas operations and the rules affecting
them have increased in recent years. For example, the EPA and environmental non-governmental organizations have conducted flyovers with optical gas imaging
cameras  to  survey  emissions  from  oil  and  natural  gas  production  facilities  and  transmission  infrastructure.  In  addition,  the  Texas  Railroad  Commission  has
increased oversight related to flaring, with reporting reviews and site inspections. While none of these activities increases our compliance obligations, they signal
the potential for increased enforcement and possible rulemaking in the future.

Climate Change

In response to findings that emissions of carbon dioxide, methane and other GHGs endanger public health and the environment, the EPA has adopted regulations
under existing provisions of the CAA that, among other things, establish construction and operating permit reviews for GHG emissions certain large stationary
sources, require the monitoring and annual reporting of GHG emissions from certain petroleum and natural gas system sources in the United States, implement
New Source Performance Standards directing the reduction of methane from certain new, modified, or reconstructed facilities in the oil and natural gas sector, and
together  with  the  Department  of  Transportation  (the  “DOT”),  implement  GHG  emissions  limits  on  vehicles  manufactured  for  operation  in  the  United  States.
Additionally, various states and groups of states have adopted or are considering adopting legislation, regulations or other regulatory initiatives that are focused on
such  areas  as  GHG  cap  and  trade  programs,  carbon  taxes,  reporting  and  tracking  programs,  and  restriction  of  emissions.  At  the  international  level,  there  is  an
agreement,  the  United  Nations-sponsored “Paris  Agreement,” for  nations  to  limit  their  GHG emissions  through  non-binding, individually-determined reduction
goals every five years after 2020. President Biden pledged the renewed participation of the United States on his first day in office. Although it is not possible at this
time to predict how legislation or new regulations that may be adopted in the Paris Agreement to address GHG emissions would impact our business, any such
future laws and regulations imposing reporting obligations on, or limiting emissions of GHGs from, our equipment and operations could require us to incur costs to
reduce emissions of GHGs associated with our operations.

Litigation risks are also increasing, as a number of cities and other local governments have sought to bring suit against the largest oil and natural gas exploration
and production companies in state or federal court, alleging, among other things, that such companies created public nuisances by producing fuels that contributed
to global warming effects, such as rising sea levels, and therefore are responsible for roadway and infrastructure damages, or alleging that the companies have been
aware of the adverse effects of climate change for some time but defrauded their investors by failing to adequately disclose those impacts.

There are also increasing financial risks for fossil fuel producers as shareholders currently invested in fossil-fuel energy companies concerned about the potential
effects of climate change may elect in the future to shift some or all of their

19

investments  into  non-energy  related  sectors.  Institutional  lenders  who  provide  financing  to  fossil-fuel  energy  companies  also  have  become  more  attentive  to
sustainable  lending  practices  and  some  of  them  may  elect  not  to  provide  funding  for  fossil  fuel  energy  companies.  Additionally,  the  lending  practices  of
institutional lenders have been the subject of intensive lobbying efforts in recent years, oftentimes public in nature, by environmental activists, proponents of the
international Paris Agreement, and foreign citizenry concerned about climate change not to provide funding for fossil fuel producers. Limitation of investments in
and financings for fossil fuel energy companies could result in the restriction, delay or cancellation of drilling programs or development or production activities.

The adoption and implementation of new or more stringent international, federal or state legislation, regulations or other regulatory initiatives that impose more
stringent standards for GHG emissions from the oil and natural gas sector or otherwise restrict the areas in which this sector may produce oil and natural gas or
generate GHG emissions could result in increased costs of compliance or costs of consuming, and thereby reduce demand for, oil and natural gas. Additionally,
political, litigation  and financial  risks may result in us restricting  or cancelling  production activities,  incurring liability for infrastructure  damages as a result of
climatic changes, or having an impaired ability to continue to operate in an economic manner. One or more of these developments could have a material adverse
effect on our business, financial condition and results of operation.

Threatened and endangered species, migratory birds and natural resources

Various federal and state statutes prohibit certain actions that adversely affect endangered or threatened species and their habitat, migratory birds, wetlands, and
natural resources. These statutes include the Endangered Species Act (“ESA”), the Migratory Bird Treaty Act (“MBTA”) and the Clean Water Act. The U.S. Fish
and Wildlife Service (“FWS”) may designate critical habitat areas that it believes are necessary for survival of threatened or endangered species. As a result of a
2011 settlement agreement, the FWS was required to determine whether to identify more than 250 species as endangered or threatened under the FSA by no later
than completion of the agency’s 2017 fiscal year. The FWS missed the deadline but reportedly continues to review new species for protected status under the ESA
pursuant to the settlement agreement.  A critical habitat designation could result in further material restrictions on federal land use or on private land use and could
delay  or  prohibit  land  access  or  development.  Where  takings  of  or  harm  to  species  or  damages  to  wetlands,  habitat,  or  natural  resources  occur  or  may  occur,
government  entities  or  at  times  private  parties  may  act  to  prevent  or  restrict  oil  and  natural  gas  exploration  activities  or  seek  damages  for  any  injury,  whether
resulting  from  drilling  or  construction  or  releases  of  oil,  wastes,  hazardous  substances  or  other  regulated  materials,  and  in  some  cases,  criminal  penalties  may
result. Similar protections are offered to migratory birds under the MBTA. Recently, there have been renewed calls to review protections currently in place for the
dunes sagebrush lizard, whose habitat includes portions of the Permian Basin, and to reconsider listing the species under the ESA.  While some of our operations
may be located in areas that are designated as habitats for endangered or threatened species or that may attract migratory birds, we believe that we are in substantial
compliance with the ESA and the MBTA, and we are not aware of any proposed ESA listings that will materially affect our operations. The federal government in
the past has issued indictments under the MBTA to several oil and natural gas companies after dead migratory birds were found near reserve pits associated with
drilling activities. However, in January 2020, the Department of Interior proposed new regulations clarifying that only the intentional taking of protected migratory
birds is subject to prosecution under the MTBA. The identification or designation of previously unprotected species as threatened or endangered in areas where
underlying property operations are conducted could cause us to incur increased costs arising from species protection measures or could result in limitations on our
development activities that could have an adverse impact on our ability to develop and produce our oil and natural gas reserves. If we were to have a portion of our
leases designated as critical or suitable habitat, it could adversely impact the value of our leases.

Hazard communications and community right to know

We are subject to federal and state hazard communication and community right to know statutes and regulations. These regulations, including, but not limited to,
the federal Emergency Planning & Community Right-to-Know Act, govern record keeping and reporting of the use and release of hazardous substances and may
require that information be provided to state and local government authorities, as well as the public.

Occupational Safety and Health Act

We are subject to a number of federal and state laws and regulations, including OSHA, and comparable state statutes that regulate the protection of the health and
safety  of  workers.  In  2016,  there  were  substantial  revisions  to  the  regulations  under  OSHA  that  may  have  an  impact  to  our  operations.  These  changes  include
among other items; record keeping and reporting, revised crystalline silica standard (which requires the oil and gas industry to implement engineering controls and
work practices to limit exposures below the new limits by June 23, 2021), naming oil and gas as a high hazard industry and requirements for a safety and health
management system. In addition, OSHA hazard communication standard requires that information be maintained about hazardous materials used or produced in
operations and that this information be provided to employees, state and local government authorities and citizens.

20

State Regulation

Texas regulates the drilling for, and the production, gathering and sale of, oil and natural gas, including imposing severance taxes and requirements for obtaining
drilling permits. Texas currently imposes a 4.6% severance tax on oil production and a 7.5% severance tax on natural gas and natural gas liquids production. States
also regulate  the method of developing new fields, the spacing and operation  of wells and the prevention  of waste of oil and natural  gas resources.  States may
regulate  rates  of  production  and  may  establish  maximum  daily  production  allowables  from  oil  and  natural  gas  wells  based  on  market  demand  or  resource
conservation, or both. States do not regulate wellhead prices or engage in other similar direct economic regulation, but we cannot assure our stockholders that they
will not do so in the future. The effect of these regulations may be to limit the amount of oil and natural gas that may be produced from our wells and to limit the
number of wells or locations we can drill.

The  petroleum  industry  is  also  subject  to  compliance  with  various  other  federal,  state  and  local  regulations  and  laws.  Some  of  those  laws  relate  to  resource
conservation and equal employment opportunity. We do not believe that compliance with these laws will have a material adverse effect on us.

Related Insurance

We maintain insurance against some risks associated with above or underground contamination that may occur as a result of our exploration, development and
production  activities.  However,  this  insurance  is  limited  to  activities  at  the  well  site,  and  there  can  be  no  assurance  that  this  insurance  will  continue  to  be
commercially available or that this insurance will be available at premium levels that justify its purchase by us. The occurrence of a significant event that is not
fully insured or indemnified against could have a materially adverse effect on our financial condition and operations.

Although we have not experienced any material adverse effect from compliance with environmental requirements, there is no assurance that this will continue. We
did not have any material capital or other non-recurring expenditures in connection with complying with environmental laws or environmental remediation matters
in 2020, nor do we anticipate that such expenditures will be material in 2021.

Employees

As of December 31, 2020, we had 61 full-time employees, of which 10 are management, 17 are technical personnel, 15 are administrative personnel and 19 are
field operations employees. Our employees are not covered under a collective bargaining agreement nor are any employees represented by a union. We consider all
relations with our employees to be satisfactory.

Subsequent to the completion of the IRM Acquisition, we added 18 full-time employees, of which two are administrative personnel and 16 are field operations
employees all of whom were former employees of IRM.

Office Leases

As of December 31, 2020, we leased office space as set forth in the following table:

The following biographies describe the business experience of our executive officers: 

Frank A. Lodzinski has served as our Chairman since December 2014 and as Executive Chairman since April 1, 2020. He served as our Chief Executive Officer
from December 2014 through March 2020. He also served as our President from December 2014 through April 2018. Previously, he served as President and Chief
Executive  Officer  of  Oak  Valley  Resources,  LLC  (“Oak  Valley”)  from  its  formation  in  December  2012  until  the  closing  of  its  strategic  combination  with
Earthstone in December 2014. Prior to his service with Oak Valley, Mr. Lodzinski was Chairman, President and Chief Executive Officer of GeoResources, Inc.
from April 2007 until its merger with Halcón Resources Corporation (“Halcón”) in August 2012 and from September 2012 until December 2012 he conducted pre-
formation activities for Oak Valley. He has over 47 years of oil and gas industry experience. In 1984, he formed Energy Resource Associates, Inc., which acquired
management and controlling interests in oil and gas limited partnerships, joint ventures and producing properties. Certain partnerships were exchanged for common

Item 1A.  Risk Factors

Our business is subject to various risks and uncertainties in the ordinary course of our business. The following summarizes significant risks and uncertainties that
may adversely affect our business, financial condition or results of operations. We cannot assure you that any of the events discussed in the risk factors below will
not occur. Further, the risks and uncertainties described below are not the only ones we face. Additional risks not presently known to us or that we currently deem
immaterial may also materially affect our business. When considering an investment in our shares of Class A Common Stock, you should carefully consider the
risk factors included below as well as those matters referenced in this report under “Cautionary Statement Concerning Forward-Looking Statements” and other
information included and incorporated by reference into this report.

Our business and operations have been and will likely continue to be adversely affected by the ongoing COVID-19 pandemic.

The spread of COVID-19 caused, and is continuing to cause, severe disruptions in the worldwide and U.S. economies, including contributing to the reduced global
and domestic demand for oil and natural gas, which has had and will likely continue to have an adverse effect on our business, financial condition and results of
operations. Moreover, since the beginning of January 2020, the COVID-19 pandemic has caused significant disruption in the financial markets both globally and in
the United States. The continued spread of COVID-19 could also negatively impact the availability of key personnel necessary to conduct our business. If COVID-
19  continues  to  spread  or  the  response  to  contain  or  mitigate  the  COVID-19  pandemic  through  the  development  and  availability  of  effective  treatments  and
vaccines, including the vaccines recently approved by the FDA for emergency use in the U.S., is unsuccessful, we could continue to experience material adverse
effects on our business, financial condition and results of operations. Due to the rapid development and fluidity of this situation, we cannot make any prediction as
to the ultimate material adverse impact of the COVID-19 pandemic on our business, financial condition and results of operations.

Oil, natural gas and natural gas liquids prices are volatile. Their prices at times since 2014 have adversely affected, and in the future may adversely affect, our
business, financial condition and results of operations and our ability to meet our

23

 
 
capital expenditure obligations and financial commitments. Volatile and lower prices may also negatively impact our stock price.

The prices we receive for our oil, natural gas and natural gas liquids production heavily influence our revenues, profitability, access to capital and future rate of
growth. These hydrocarbons are commodities, and therefore, their prices may be subject to wide fluctuations in response to relatively minor changes in supply and
demand.  Historically,  the  market  for  oil,  natural  gas  and  natural  gas  liquids  has  been  volatile.  For  example,  during  the  period  from  January  1,  2014  through
December 31, 2020, the WTI spot price for oil declined from a high of $107.95 per Bbl in June 2014 to -$36.98 per Bbl in April 2020. The Henry Hub spot price
for natural gas has declined from a high of $8.15 per MMBtu in February 2014 to a low of $1.33 per MMBtu in September 2020. During 2020, WTI spot prices
ranged from -$36.98 to $63.27 per Bbl and the Henry Hub spot price of natural gas ranged from $1.33 to $3.14 per MMBtu. Likewise, natural gas liquids, which
are  made  up  of  ethane,  propane,  isobutane,  normal  butane  and  natural  gasoline,  each  of  which  have  different  uses  and  different  pricing  characteristics,  have
experienced  significant  declines  in realized  prices  since  the  fall  of 2014. The  prices  we receive  for  oil, natural  gas  and  natural  gas  liquids  we produce  and  our
production levels depend on numerous factors beyond our control, including:

•
•
•
•
•

•
•
•
•
•
•
•
•
•
•
•
•

worldwide, regional and local economic and financial conditions impacting supply and demand;
the level of global exploration, development and production;
the level of global supplies, in particular due to supply growth from the United States;
the price and quantity of oil, natural gas and NGLs imports to and exports from the U.S.;
political conditions in or affecting other oil, natural gas and natural gas liquids producing countries and regions, including the current conflicts in
the Middle East, Asia and Eastern Europe;
actions of the OPEC and state-controlled oil companies relating to production and price controls;
the extent to which U.S. shale producers become swing producers adding or subtracting to the world supply totals;
future regulations prohibiting or restricting our ability to apply hydraulic fracturing to our wells;
current and future regulations regarding well spacing;
prevailing prices and pricing differentials on local oil, natural gas and natural gas liquids price indices in the areas in which we operate;
localized and global supply and demand fundamentals and transportation, gathering and processing availability;
weather conditions;
technological advances affecting fuel economy, energy supply and energy consumption;
the effect of energy conservation measures, alternative fuel requirements and increasing demand for alternatives to oil and natural gas;
global or national health concerns, including health epidemics such as the COVID-19 pandemic at the beginning of 2020;
the price and availability of alternative fuels; and
domestic, local and foreign governmental regulation and taxes.

Lower oil, natural gas and natural gas liquids prices have and may continue to reduce our cash flows and borrowing capacity. We may be unable to obtain needed
capital or financing on satisfactory terms, which could lead to a decline in our hydrocarbon reserves as existing reserves are depleted. A decrease in prices could
render development projects and producing properties uneconomic, potentially resulting in a loss of mineral leases. Low commodity prices have, at times, caused
significant  downward  adjustments  to  our  estimated  proved  reserves,  and  may  cause  us  to  make  further  downward  adjustments  in  the  future.  Furthermore,  our
borrowing capacity could be significantly affected by decreased prices. A sustained decline in oil, natural gas and natural gas liquids prices could adversely impact
our borrowing base in future borrowing base redeterminations, which could trigger repayment obligations under the Credit Agreement to the extent our outstanding
borrowings  exceed  the  redetermined  borrowing  base  and  could  otherwise  materially  and  adversely  affect  our  future  business,  financial  condition,  results  of
operations, liquidity or ability to finance planned capital expenditures. In addition, lower oil, natural gas and natural gas liquids gas prices may cause a decline in
the market price of our shares.

As a result of low prices for oil, natural gas and natural gas liquids, we may be required to take significant future write-downs of the financial carrying values
of our properties.

Accounting  rules  require  that  we  periodically  review  the  carrying  value  of  our  proved  and  unproved  properties  for  possible  impairment.  Based  on  prevailing
commodity  prices  and  specific  market  factors  and  circumstances  at  the  time  of  prospective  impairment  reviews,  and  the  continuing  evaluation  of  development
plans,  production  data,  economics  and  other  factors,  we  may  be  required  to  significantly  write-down  the  financial  carrying  value  of  our  oil  and  natural  gas
properties, which constitutes a non-cash charge to earnings. We may incur impairment charges in the future, which could have a material adverse effect on our
results of operations for the periods in which such charges are recorded.

24

A write-down could occur when oil and natural gas prices are low or if we have substantial downward adjustments to our estimated proved oil and natural gas
reserves, if operating costs or development costs increase over prior estimates, or if exploratory drilling is unsuccessful.

The capitalized costs of our oil and natural gas properties, on a field-by-field basis, may exceed the estimated future net cash flows of that field. If so, we would
record impairment charges to reduce the capitalized costs of such field to our estimate of the field’s fair market value. Unproved properties are evaluated at the
lower of cost or fair market value. These types of charges will reduce our earnings and stockholders’ equity and could adversely affect our stock price.

We periodically assess our properties for impairment based on future estimates of proved and non-proved reserves, oil and natural gas prices, production rates and
operating, development and reclamation costs based on operating budget forecasts. Once incurred, an impairment charge cannot be reversed at a later date even if
price increases of oil and/or natural gas occur and in the event of increases in the quantity of our estimated proved reserves.

If  oil,  natural  gas  and  natural  gas  liquids  prices  fall  below  current  levels  for  an  extended  period  of  time  and  all  other  factors  remain  equal,  we  may  incur
impairment charges in the future. Such charges could have a material adverse effect on our results of operations for the periods in which they are recorded. See
Note 7. Oil and Natural Gas Properties to the Notes to Consolidated Financial Statements included in this report for additional information.

Any significant reduction in our borrowing base under our Credit Agreement may negatively impact our liquidity and, consequently, our ability to fund our
operations, including capital expenditures, and we may not have sufficient funds to repay borrowings under our Credit Agreement or any other obligation if
required as a result of a borrowing base redetermination.

Availability  under  the  Credit  Agreement  is  currently  subject  to  a  borrowing  base  of  $360.0  million,  as  increased  with  the  closing  of  the  IRM  Acquisition  on
January 7, 2021. The borrowing base is subject to scheduled semiannual redeterminations (on or about May 1 and November 1), as well as other lender-elective
borrowing  base  redeterminations.  The  lenders  can  unilaterally  adjust  the  borrowing  base  and  the  borrowings  permitted  to  be  outstanding  under  the  Credit
Agreement.  Reductions  in  estimates  of  our  oil,  natural  gas  and  natural  gas  liquids  reserves  may  result  in  a  reduction  in  our  borrowing  base  under  the  Credit
Agreement (if prices are kept constant). Reductions in our borrowing base under the Credit Agreement could also arise from other factors, including but not limited
to:

•
•
•
•
•
•
•

lower commodity prices or production;
increased leverage ratios;
inability to drill or unfavorable drilling results;
changes in oil, natural gas and natural gas liquids reserve engineering techniques;
increased operating and/or capital costs;
the lenders’ inability to agree to an adequate borrowing base; or
adverse changes in the lenders’ practices (including required regulatory changes) regarding estimation of reserves.

As of December 31, 2020, we had $115.0 million of borrowings outstanding under the Credit Agreement with a borrowing base of $240 million. When adjusted to
include the IRM Acquisition on January 7, 2021, we had $260 million of long-term debt outstanding under the Credit Agreement with a borrowing base of $360
million. We may make further borrowings under the Credit Agreement in the future. Any significant reduction in our borrowing base under the Credit Agreement
as a result of borrowing base redeterminations or otherwise will negatively impact our liquidity and our ability to fund our operations and, as a result, could have a
material adverse effect on our financial position, results of operations and cash flows. Further, if the outstanding borrowings under the Credit Agreement were to
exceed the borrowing base as a result of any such redetermination, we could be required to repay the excess.

Unless we replace our reserves, our production and estimated reserves will decline, which may adversely affect our financial condition, results of operations
and/or cash flows.

Producing oil and natural gas reservoirs are generally characterized by declining production rates that may vary depending upon reservoir characteristics and other
factors. Decline rates are typically greatest early in the productive life of a well, particularly horizontal wells. Estimates of the decline rate of an oil or natural gas
well are inherently imprecise and may be less precise with respect to new or emerging oil and natural gas formations with limited production histories than for
more developed formations with established production histories. Our production levels and the reserves that we currently expect to recover from our wells will
change if production from our existing wells declines in a different manner than we have estimated and can change under other circumstances. Thus, our estimated
future  oil  and natural  gas  reserves  and production  and, therefore,  our  cash flows and  results  of operations  are  highly dependent  upon our success  in efficiently
developing and exploiting our current properties and economically finding or acquiring additional recoverable reserves. We may not be able to develop, find or
acquire additional

25

reserves to replace our current and future production at acceptable costs. If we are unable to replace our current and future production, our cash flows and the value
of our reserves may decrease, adversely affecting our business, financial condition and results of operations.

Estimates of proved oil and natural gas reserves involve assumptions and any material inaccuracies in these assumptions will materially affect the quantities
and the value of those reserves.

This report contains estimates of our proved oil and natural gas reserves. These estimates are based upon various assumptions, including assumptions required by
SEC  regulations  relating  to  oil  and  natural  gas  prices,  drilling  and  operating  expenses,  capital  expenditures,  taxes  and  availability  of  funds.  The  process  of
estimating  oil  and  natural  gas  reserves  is  complex  and  requires  significant  decisions,  complex  analyses  and  assumptions  in  evaluating  available  geological,
geophysical, engineering and economic data for each reservoir. Therefore, these estimates are inherently imprecise.

Our actual future production, oil and natural gas prices, revenues, taxes, development expenditures, operating expenses and quantities of recoverable oil and natural
gas reserves will vary from those estimated. Any significant variance will likely materially affect the estimated quantities and the estimated value of our reserves.
In  addition,  we  may  later  adjust  estimates  of  proved  reserves  to  reflect  production  history,  results  of  exploration  and  development  activities,  prevailing  oil  and
natural gas prices and other factors, many of which are beyond our control.

Quantities of estimated proved reserves are based on economic conditions in existence during the period of assessment. Changes to oil, natural gas and natural gas
liquids  prices  in  the  markets  for  these  commodities  may  shorten  the  economic  lives  of  certain  fields  because  it  may  become  uneconomical  to  produce  all
recoverable reserves in such fields, which may reduce proved reserves estimates.

Negative  revisions  in  the  estimated  quantities  of  proved  reserves  have  the  effect  of  increasing  the  rates  of  depletion  on  the  affected  properties,  which  decrease
earnings  or  result  in  losses  through  higher  depletion  expense.  These  revisions,  as  well  as  revisions  in  the  assumptions  of  future  estimated  cash  flows  of  those
reserves, may also trigger impairment losses on certain properties, which may result in non-cash charges to earnings. See Note 7. Oil and Natural Gas Properties
to the Notes to Consolidated Financial Statements included in this report.

The  development  of  our  estimated  proved undeveloped reserves may  take  longer  and  may  require  higher  levels  of  capital expenditures  than  we  currently
anticipate. Therefore, our estimated proved undeveloped reserves may not be ultimately developed or produced.

At  December  31,  2020,  approximately  51%  of  our  estimated  proved  reserves  were  classified  as  proved  undeveloped.  The  development  of  our
estimated proved undeveloped reserves of 40,577 MBOE will require an estimated $285.1 million of development capital over the next five years. Development of
these  reserves  may  take  longer  and  require  higher  levels  of  capital
 of
our proved undeveloped reserves is dependent on successful drilling and completion results, future commodity prices, costs and economic assumptions that align
with  our  internal  forecasts,  as  well  as  access  to  liquidity  sources,  such  as  the  capital  markets,  the  Credit  Agreement  and  derivative  contracts.  Delays  in  the
development  of  our  reserves,  increases  in  costs  to  drill  and  develop  such  reserves,  or  decreases  in  commodity  prices  will  reduce  the  PV-10  value  of  our
estimated  proved  undeveloped  reserves  and  future  net  revenues  estimated  for  such  reserves  and  may  result  in  some  projects  becoming  uneconomic.  Moreover,
under the SEC regulations, we may be required to write down our proved undeveloped reserves if we do not drill or have a development plan to drill wells within a
prescribed five-year period. The estimated reserve data assumes that we will make specified capital expenditures to timely develop our reserves. The estimates of
these oil and natural gas reserves and the costs associated with development of these reserves have been prepared in accordance with SEC regulations; however,
actual capital expenditures may vary from estimated capital expenditures, development may not occur as scheduled and actual results may not be as estimated.

 expenditures  than  we  currently  anticipate.

 The  future  development

The standardized measure of discounted future net cash flows from our estimated proved reserves may not be the same as the current market value of our
estimated oil and natural gas reserves.

You should not assume that the standardized measure of discounted future net cash flows from our estimated proved reserves set forth in this report is the current
market  value  of  our  estimated  oil  and  natural  gas  reserves.  In  accordance  with  SEC  requirements  in  effect  at  December  31,  2020  and  2019,  we  based  the
discounted future net cash flows from our proved reserves on the 12-month first-day-of-the-month oil and natural gas unweighted arithmetic average prices without
giving effect to derivative transactions and costs in effect as of the date of the estimate, holding prices and costs constant through the life of the properties. Actual
future net cash flows from our oil and natural gas properties will be affected by factors such as: the actual prices we receive for oil and natural gas; the actual cost
of development and production expenditures; the amount and timing of actual production; and changes in governmental regulations or taxation.

26

The timing of both our production and incurring expenses related to developing and producing oil and natural gas properties will affect the timing and amount of
actual future net revenues from proved reserves, and thus their actual present value. In addition, the 10% discount factor we use when calculating standardized
measure may not be the most appropriate discount factor based on interest rates in effect from time to time and risks associated with our business or the oil and
natural gas industry in general. As a corporation, we are treated as a taxable entity for statutory income tax purposes and our future income taxes will be dependent
on  our  future  taxable  income.  Actual  future  prices  and  costs  may  differ  materially  from  those  used  in  the  estimates  included  in  this  report  which  could  have  a
material effect on the value of our estimated reserves.

Our development and exploratory drilling efforts and our well operations may not be profitable or achieve our targeted returns.

We have acquired significant  amounts of unproved property in order to further our development efforts and expect to continue to undertake acquisitions in the
future. Development and exploratory drilling and production activities are subject to many risks, including the risk that no commercially productive reservoirs will
be  discovered.  We  acquire  unproved  properties  and  lease  undeveloped  acreage  that  we  believe  will  enhance  our  growth  potential  and  increase  our  results  of
operations over time. However, we cannot assure you that all prospects will be economically viable or that we will not abandon our leaseholds. Additionally, we
cannot assure you that unproved property acquired by us or undeveloped acreage leased by us will be profitably developed, that wells drilled by us in prospects that
we pursue will be productive or that we will recover all or any portion of our investment in such unproved property or wells.

Properties we acquire may not produce as projected and we may be unable to determine reserve potential, identify liabilities associated with the properties that
we acquire or obtain protection from sellers against such liabilities.

Acquiring oil and natural gas properties requires us to assess reservoir and infrastructure characteristics, including recoverable reserves, development and operating
costs and potential environmental and other liabilities. Such assessments are inexact and inherently uncertain. In connection with the assessments, we perform a
review of the subject properties, but such a review will not reveal all existing or potential problems. In the course of our due diligence, we may not inspect every
well or pipeline. We cannot necessarily observe structural and environmental problems, such as pipe corrosion, when an inspection is made. We may not be able to
obtain  contractual  indemnities  from the  seller  for liabilities  created  prior to our purchase  of a property.  We may be required  to assume  the risk of the physical
condition of properties in addition to the risk that they may not perform in accordance with our expectations. If properties we acquire do not produce as projected
or have liabilities we were unable to identify, we could experience a decline in our reserves and production, which could adversely affect our business, financial
condition and results of operations.

Future  drilling  and  completion  activities  associated  with  identified  drilling  locations  may  be  adversely  affected  by  factors  that  could  materially  alter  the
occurrence or timing of their drilling and completion, which in certain instances could prevent production prior to the expiration date of mineral leases for
such locations.

Although our management team has identified  numerous  potential drilling locations as a part of our long-range planning related to future drilling activities on our
existing acreage, our ability to drill and develop these locations depends on a number of factors, which are beyond our control, including, the availability and cost
of capital, oil, natural gas and natural gas liquids prices, drilling and production costs, the availability of drilling services and equipment, drilling results (including
the  impact  of  increased  horizontal  drilling  density  and  longer  laterals),  lease  expirations,  gathering  systems,  marketing  and  pipeline  transportation  constraints,
regulatory permits and approvals and other factors. In addition, we may alter the spacing between our anticipated drilling locations, which could impact the number
of  our  drilling  locations,  the  number  of  wells  that  we  drill,  and  the  volumes  of  oil  and  gas  we  ultimately  recover.  As  such,  our  actual  drilling  and  completion
activities, may materially differ from those presently anticipated. Accordingly, it is uncertain to what degree that these potential drilling locations will be developed
or  if  we  will  be  able  to  produce  significant  oil,  natural  gas  and  natural  gas  liquids  from  these  or  any  other  potential  drilling  locations.    Unless  production  is
established, in accordance with the terms of mineral leases that are associated with these locations, such leases could expire.

Many 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 we or other operators may take when drilling, completing, or operating wells that we or they own.

Many  of  our  properties  are  in  reservoirs  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 by us or other operators could cause depletion of our proved
reserves and may inhibit our ability to further develop our proved reserves. In addition, completion operations and

27

other activities conducted on adjacent or nearby wells by us or other operators 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  brought  into  production  until  all  wells  on  the  pad  are  drilled  and
completed and the drilling rig is moved from the location, multi-well pad drilling delays the commencement of production from a given pad, which may cause
volatility in our operating results. In addition, problems affecting one pad could adversely affect production from all wells on such pad. As a result, multi-well pad
drilling can cause delays in the scheduled commencement of production or interruptions in ongoing production.

The  unavailability  or  high  cost  of  equipment,  supplies,  personnel  and  oilfield  services  used  to  drill  and  complete  wells  could  adversely  affect  our  ability  to
execute our development plans within our budget and on a timely basis.

The  demand  for  drilling  rigs,  pipe  and  other  equipment  and  supplies,  as  well  as  for  qualified  and  experienced  field  personnel  to  drill  wells  and  conduct  field
operations, geologists, geophysicists, engineers and other professionals in the oil and natural gas industry, can fluctuate significantly, often in correlation with oil
and natural gas prices, causing periodic shortages. Our operations are concentrated in areas in which activity has increased rapidly, and as a result, demand for such
drilling rigs, equipment and personnel, as well as access to transportation, processing and refining facilities in these areas, has increased, as have the costs for those
items. In addition, to the extent our suppliers source their products or raw materials from foreign markets, the cost of such equipment could be impacted if the
United States imposes tariffs on imported goods from countries where these goods are produced. Such shortages or cost increases could delay or cause us to incur
significant expenditures that are not provided for in our capital budget, which could have a material adverse effect on our business, financial condition or results of
operations.

Our acquisition, development and exploitation projects require substantial capital expenditures. We may be unable to obtain required capital or financing on
satisfactory terms, which could limit growth or lead to a decline in our reserves.

The oil and natural gas industry is capital intensive. We make and expect to continue to make substantial capital expenditures for the acquisition and development
of oil and natural gas reserves. We expect to fund our 2021 capital expenditures with cash on hand, cash generated by operations, borrowings under the Credit
Agreement and possibly through additional capital market transactions. The actual amount and timing of our future capital expenditures may differ materially from
our estimates as a result of, among other things, oil and natural gas prices, actual drilling results, the availability of high-quality drilling rigs and other services and
equipment and regulatory, technological and competitive developments. A reduction in commodity prices from current levels may result in a decrease in our actual
capital expenditures, which would negatively impact our ability to grow production.

Our cash flow from operations and access to capital are subject to a number of variables, including: our proved reserves; the level of hydrocarbons we are able to
produce from existing wells; the prices at which our production is sold; our ability to acquire, locate and produce reserves; and our ability to borrow under the
Credit Agreement.

If our revenues or the borrowing base under the Credit Agreement decrease as a result of low oil and natural gas prices, operating difficulties, declines in reserves
or for any other reason, we may have limited ability to obtain the capital necessary to sustain our operations and growth at current levels. If additional capital is
needed,  we  may  not  be  able  to  obtain  debt  or  equity  financing  on  terms  acceptable  to  us,  if  at  all.  The  failure  to  obtain  additional  financing  could  result  in  a
curtailment of our operations relating to development of our properties, which in turn could lead to a decline in our reserves and production and would adversely
affect our business, financial condition and results of operations.

A negative shift in investor sentiment towards the oil and gas industry could adversely affect our ability to raise equity and debt capital.

Much  of  the  investor  community  has  developed  negative  sentiment  towards  investing  in  our  industry.  Recent  equity  returns  in  the  sector  versus  other  industry
sectors have led to lower oil and gas representation in certain key equity market indices. Some investors, including certain public and private fund management
firms, pension funds, university endowments and family foundations, have stated policies to reduce or eliminate their investments in the oil and gas sector based on
environmental, social and governance considerations. Certain other stakeholders have pressured private equity firms and commercial and investment banks to stop
funding oil and gas projects. Such developments have resulted and could continue to result in downward pressure on the stock prices of oil and gas companies,
including ours. This may also result in a reduction of available capital funding for potential development projects, further impacting our future financial results.

28

We have incremental cash inflows and outflows as a result of our hedging activities. To the extent we are unable to obtain future hedges at attractive prices or
our derivative activities are not effective, our cash flows and financial condition may be adversely impacted.

In  an  effort  to  achieve  more  predictable  cash  flows  and  reduce  our  exposure  to  adverse  fluctuations  in  the  prices  of  oil  and  natural  gas,  we  often  enter  into
derivative instrument contracts for a portion of our oil and natural gas production, including swaps, collars, puts and basis swaps. We recognize all derivatives as
either  assets  or  liabilities,  measured  at  fair  value,  and  recognize  changes  in  the  fair  value  of  derivatives  in  current  earnings.  Accordingly,  our  earnings  may
fluctuate  significantly  and  our  results  of  operations  may  be  significantly  and  adversely  affected  because  of  changes  in  the  fair  market  value  of  our  derivative
instruments. As our derivative instrument contracts expire, there is no assurance that we will be able to replace them comparably.

Derivative instruments can expose us to the risk of financial loss in varying circumstances, including, but not limited to, when: production is less than the volume
covered by the derivative instruments; the counter-party to the derivative instrument defaults on its contractual obligations; there is an increase in the differential
between the underlying price stated in the derivative instrument contract and actual prices received; or there are issues with regard to legal enforceability of such
instruments.

For  additional  information  regarding  our  hedging  activities,  please  see  Item  7.  Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of
Operations and Note 6. Derivative Financial Instruments in the Notes to Consolidated Financial Statements included in this report for additional information.

The oil and natural gas industry is highly competitive, and our small size puts us at a disadvantage in competing for resources.

The  oil  and  natural  gas  industry  is  highly  competitive  particularly  in  the  Permian  Basin  of  Texas  where  our  properties  and  operations  are  concentrated.  We
compete with major integrated and larger independent oil and natural gas companies in seeking to acquire desirable oil and natural gas properties and leases and for
the equipment and services required to develop and operate properties. Many of our competitors have financial and other resources that are substantially greater
than ours, which makes acquisitions of acreage or producing properties at economic prices difficult. Significant competition also exists in attracting and retaining
technical personnel, including geologists, geophysicists, engineers, landmen and other specialists, as well as financial and administrative personnel hence we may
be at a competitive disadvantage to companies with larger financial resources than ours.

Failure to complete additional acquisitions could limit our potential growth.

Our  future  success  is  highly  dependent  on  our  ability  to  acquire  and  develop  mineral  leases  and  oil  and  gas  properties  with  economically  recoverable  oil  and
natural gas reserves. Without continued successful acquisition, of economic development projects, our current estimated oil and natural gas reserves will decline
due  to  continued  production  activities.  Acquiring  additional  oil  and  natural  gas  properties,  or  businesses  that  own  or  operate  such  properties  is  an  important
component of our business strategy. If we identify an appropriate acquisition candidate, management may be unable to negotiate mutually acceptable terms with
the  seller,  finance  the  acquisition  or  obtain  the  necessary  regulatory  approvals.  Our  limited  access  to  financial  resources  compared  to  larger,  better  capitalized
companies may limit our ability to make future acquisitions. If we are unable to complete suitable acquisitions, it may be more difficult to replace and increase our
reserves, and an inability to replace our reserves may have a material adverse effect on our financial condition and results of operations.

Acquisitions involve a number of risks, including the risk that we will discover unanticipated liabilities or other problems associated with the acquired business
or property.

In assessing potential acquisitions, we consider information available in the public domain and information provided by the seller. In the event publicly available
data is limited, then, by necessity, we may rely to a large extent on information that may only be available from the seller, particularly with respect to drilling and
completion costs and practices, geological, geophysical and petrophysical data, detailed production data on existing wells, and other technical and cost data not
available in the public domain. Accordingly, the review and evaluation of businesses or properties to be acquired may not uncover all existing or relevant data,
obligations or actual or contingent liabilities that could adversely impact any business or property to be acquired and, hence, could adversely affect us as a result of
the acquisition. These issues may be material and could include, among other things, unexpected environmental liabilities, title defects, unpaid royalties, taxes or
other liabilities. If we acquire properties on an “as-is” basis, we may have limited or no remedies against the seller with respect to these types of problems.

The  success  of  any  acquisition  that  we  complete  will  depend  on  a  variety  of  factors,  including  our  ability  to  accurately  assess  the  reserves  associated  with  the
acquired  properties,  assumptions  related  to  future  oil  and  natural  gas  prices  and  operating  costs,  potential  environmental  and  other  liabilities  and  other  factors.
These assessments are often inexact and subjective. As a result,

29

we may not recover the purchase price of a property from the sale of production from the property or recognize an acceptable return from such sales or operations.

Our ability to achieve the benefits that we expect from an acquisition will also depend on our ability to efficiently integrate the acquired operations. Management
may be required to dedicate significant time and effort to the integration process, which could divert its attention from other business opportunities and concerns.
The  challenges  involved  in  the  integration  process  may  include  retaining  key  employees  and  maintaining  employee  morale,  addressing  differences  in  business
cultures, processes and systems and developing internal expertise regarding acquired properties.

We may incur substantial losses and be subject to substantial liability claims as a result of our oil and natural gas operations, including our drilling operations.

Oil and natural gas exploration, development and production activities are subject to numerous significant operating risks, including the possibility of:

•
•
•
•
•
•

unanticipated, abnormally pressured formations;
significant mechanical difficulties, such as stuck drilling and service tools and casing collapses;
blowouts, fires and explosions;
personal injuries and death;
uninsured or underinsured losses; and
environmental  hazards,  such  as  uncontrollable  flows  of  oil,  natural  gas,  brine,  well  fluids,  toxic  gas  or  other  pollution  into  the  environment,
including groundwater contamination.

Any  of  these  operating  hazards  could  cause  damage  to  properties,  reduced  cash  flows,  serious  injuries,  fatalities,  oil  spills,  discharge  of  hazardous  materials,
remediation and clean-up costs and other environmental damages, which could expose us to significant liabilities. We may elect not to obtain insurance for any or
all  of  these  risks  if  we  believe  that  the  cost  of  available  insurance  is  excessive  relative  to  the  risks  presented.  In  addition,  pollution  and  environmental  risks
generally are not fully insurable. The occurrence of an event that is not fully covered by insurance could have a material adverse effect on our business, financial
condition and results of operations.

The nature of our business and assets exposes us to significant compliance costs and liabilities.

Our  operations  involving  the  exploration,  development  and  production  of  hydrocarbons  are  subject  to  stringent  federal,  state,  and  local  laws  and  regulations
governing  the  discharge  of  materials  into  the  environment  as  well  as  protection  of  the  environment,  operational  safety,  and  related  employee  health  and  safety
matters. Laws and regulations applicable to us include those relating but not limited to the following: land use restrictions; delivery of our oil and natural gas to
market; drilling bonds and other financial responsibility requirements; spacing of wells; air emissions; property unitization and pooling; habitat and endangered
species protection, reclamation and remediation; containment and disposal of hazardous substances, oil field waste and other waste materials; drilling permits; use
of saltwater injection wells, which affects the disposal of saltwater from our wells; safety precautions; prevention of oil spills; operational reporting; and taxation
and royalties.

Compliance  with  these  laws  and  regulations  is  a  significant  cost  of  doing  business.  Failure  to  comply  with  applicable  laws  and  regulations  may  result  in  the
assessment  of administrative,  civil,  and  criminal  penalties;  the  imposition  of  investigatory  and remedial  liabilities;  the  issuance  of injunctions  that  may  restrict,
inhibit or prohibit our operations; and claims of damages to property or persons.

Some environmental laws and regulations impose strict liability, which means that in some situations we could be exposed to liability for clean-up costs and other
damages  as  a  result  of  conduct  that  was  lawful  at  the  time  it  occurred  or  for  the  conduct  of  prior  operators  of  properties  we  acquired  or  of  other  third  parties.
Similarly,  some  environmental  laws and  regulations  impose  joint  and several  liability,  meaning  that  we could be held  responsible  for more  than our share  of a
particular  reclamation  or  other  obligation,  and  potentially  the  entire  obligation,  where  other  parties  were  involved  in  the  activity  giving  rise  to  the  liability.  In
addition, we may be required to make large and unanticipated capital expenditures to comply with applicable laws and regulations, for example by installing and
maintaining  pollution  control  devices.  Similarly,  our  actual  plugging  and  abandonment  obligations  may  be  more  than  our  estimates.  It  is  not  possible  for  us  to
estimate reliably the amount and timing of all future expenditures related to environmental matters, but we estimate that they will be material. Environmental risks
are generally not fully insurable.

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

We engage third parties to provide hydraulic fracturing or other well stimulation services to us in connection with many of the wells for which we are the operator.
Federal, state and local governments have been adopting or considering restrictions on or prohibitions of fracturing in areas where we currently conduct operations,
or in the future plan to conduct operations.

30

Consequently, we could be subject to additional levels of regulation, operational delays or increased operating costs and could have additional regulatory burdens
imposed upon us that could make it more difficult to perform hydraulic fracturing and increase our costs of compliance and doing business.

From  time  to  time,  for  example,  legislation  has  been  proposed  in  Congress  to  amend  the  SDWA  to  require  federal  permitting  of  hydraulic  fracturing  and  the
disclosure  of  chemicals  used  in  the  hydraulic  fracturing  process.  Further,  the  EPA  completed  a  study  finding  that  hydraulic  fracturing  could  potentially  harm
drinking  water  resources  under  adverse  circumstances  such  as  injection  directly  into  groundwater  or  into  production  wells  lacking  mechanical  integrity.  Other
governmental reviews have also been recently conducted or are under way that focus on environmental aspects of hydraulic fracturing. At this time, it is uncertain
when, or if, the rules will be implemented, and what impact they would have on our operations. Further, legislation to amend the SDWA to repeal the exemption
for hydraulic fracturing (except when diesel fuels are used) from the definition of “underground injection” and require federal permitting and regulatory control of
hydraulic  fracturing,  as  well  as  legislative  proposals  to  require  disclosure  of  the  chemical  constituents  of  the  fluids  used  in  the  fracturing  process,  have  been
proposed in recent sessions of Congress. Several states and local jurisdictions in which we operate also have adopted or are considering adopting regulations that
could restrict or prohibit hydraulic fracturing in certain circumstances, impose more stringent operating standards and/or require the disclosure of the composition
of hydraulic fracturing fluids.

More  recently,  federal  and  state  governments  have  begun  investigating  whether  the  disposal  of  produced  water  into  underground  injection  wells  has  caused
increased seismic activity in certain areas. For example, in December 2016, the EPA released its final report regarding the potential impacts of hydraulic fracturing
on  drinking  water  resources,  concluding  that  “water  cycle”  activities  associated  with  hydraulic  fracturing  may  impact  drinking  water  resources  under  certain
circumstances  such  as  water  withdrawals  for  fracturing  in  times  or  areas  of  low  water  availability,  surface  spills  during  the  management  of  fracturing  fluids,
chemicals or produced water, injection of fracturing fluids into wells with inadequate mechanical integrity, injection of fracturing fluids directly into groundwater
resources, discharge of inadequately treated fracturing wastewater to surface waters, and disposal or storage of fracturing wastewater in unlined pits. The results of
these  studies  could  lead  federal  and  state  governments  and  agencies  to  develop  and  implement  additional  regulations.  In  addition,  on  June  28,  2016,  the  EPA
published a final rule prohibiting the discharge of wastewater from onshore unconventional oil and natural gas extraction facilities to publicly owned wastewater
treatment  plants.  The  EPA  is  also  conducting  a  study  of  private  wastewater  treatment  facilities  (also  known  as  centralized  waste  treatment  (“CWT”)  facilities)
accepting  oil  and  natural  gas  extraction  wastewater.  The  EPA  is  collecting  data  and  information  related  to  the  extent  to  which  CWT  facilities  accept  such
wastewater,  available  treatment  technologies  (and  their  associated  costs),  discharge  characteristics,  financial  characteristics  of  CWT  facilities,  and  the
environmental impacts of discharges from CWT facilities.

The proliferation of regulations may limit our ability to operate. If the use of hydraulic fracturing is limited, prohibited or subjected to further regulation, these
requirements could delay or effectively prevent the extraction of oil and natural gas from formations which would not be economically viable without the use of
hydraulic fracturing. This could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Extreme weather conditions could adversely affect our ability to conduct drilling, completion and production activities in the areas where we operate.

Our  exploitation  and  development  activities  and  equipment  could  be  adversely  affected  by  extreme  weather  conditions,  such  as  hurricanes  or  freezing
temperatures, which may cause a loss of production from temporary cessation of activity from regional power outages or lost or damaged facilities and equipment.
Such  extreme  weather  conditions  could  also  impact  access  to  our  drilling  and  production  facilities  for  routine  operations,  maintenance  and  repairs  and  the
availability of and our access to, necessary third-party services, such as gathering, processing, compression and transportation services. These constraints and the
resulting shortages or high costs could delay or temporarily halt our operations and materially increase our operation and capital costs, which could have a material
adverse effect on our business, financial condition and results of operations.

The adoption of climate change legislation or regulations restricting emission of greenhouse gases, investor pressure concerning climate-related disclosures,
and lawsuits could result in increased operating costs and reduced demand for the oil and gas we produce as well as reductions in the availability of capital.

Studies have found that emission of certain gases, commonly referred to as greenhouse gases (“GHGs”), impact the earth’s climate. The U.S. Congress and various
states  have  been  evaluating,  and  in  some  cases  implementing,  climate-related  legislation  and  other  regulatory  initiatives  that  restrict  emissions  of  GHGs.  On
January 20, 2021, President Biden’s first day in office, he signed an executive order on climate action and reconvened an interagency working group to establish
interim  and  final  social  costs  of  three  GHGs:  carbon  dioxide,  nitrous  oxide,  and  methane.  Carbon  dioxide  is  released  during  the  combustion  of  fossil  fuels,
including oil, natural gas, and NGLs, and methane is a primary component of natural gas. The Biden administration stated it will use updated social cost figures to
inform federal regulations and major agency actions and to justify

31

aggressive  climate  action  as  the  United  States  moves  toward  a  “100%  clean  energy”  economy  with  net-zero  GHG  emissions.  These  actions  could  result  in
increased costs and reduced demand for our products.

In December 2009, the EPA published its findings that emissions of GHGs present an endangerment to public health and the environment because emissions of
such  gases  are  contributing  to  the  warming  of  the  earth’s  atmosphere  and  other  climatic  changes.  Based  on  these  findings,  the  EPA  adopted  regulations  under
existing provisions of the Federal Clean Air Act that establish Prevention of Significant Deterioration (“PSD”) and Title V permit reviews for GHG emissions from
certain large stationary sources. Facilities required to obtain PSD and/or Title V permits under EPA’s GHG Tailoring Rule for their GHG emissions also may be
required to meet “Best Available Control Technology” standards that will be established by the states or, in some cases, by the EPA on a case-by-case basis. The
EPA has also adopted rules requiring the monitoring and reporting of GHG emissions from specified sources in the United States, including, among others, certain
oil and natural gas production facilities on an annual basis, which includes certain of our operations. In recent proposed rulemaking, the EPA is widening the scope
of  annual  GHG  reporting  to  include  not  only  activities  associated  with  completion  and  workover  of  natural  gas  wells  with  hydraulic  fracturing  and  activities
associated  with  oil  and  natural  gas  production  operations,  but  also  completions  and  workovers  of  oil  wells  with  hydraulic  fracturing,  gathering  and  boosting
systems, and transmission pipelines.

While  the  U.S.  Congress  has  considered  legislation  to  reduce  emissions  of  GHGs  in  recent  years,  it  has  not  adopted  any  significant  GHG  legislation.  This  is
expected to change with the Democratic Party now in control of the House of Representatives, the Senate, and the office of the President. In the absence of federal
GHG legislation, a number of state and regional efforts have emerged, aimed at tracking and/or reducing GHG emissions through cap-and-trade programs, which
typically require major sources of GHG emissions, such as electric power plants, to acquire and surrender emission allowances in return for emitting GHGs. Any
future laws or regulations that require reporting of, or otherwise limit emissions of, GHGs from our equipment and operations could require us to both develop and
implement new practices aimed at reducing GHG emissions, such as emissions control technologies, and monitor and report GHG emissions associated with our
operations, any of which could increase our operating costs and could adversely affect demand for the oil and natural gas that we produce. At this time, it is not
possible to quantify the impact of such future laws and regulations on our business.

Several policy makers and political candidates have made, or expressed support for, a variety of more comprehensive proposals, such as cap-and-trade or carbon
tax programs, as well as the more sweeping “green new deal” resolutions the U.S. Congress introduced in early 2019. As generally proposed, the “green new deal”
includes  (i)  a  cap-and-trade  program  capping  overall  GHG  emissions  on  an  economy-wide  basis  and  requiring  major  sources  of  GHG  emissions  or  major  fuel
producers  to  acquire  and  surrender  emission  allowances  and  (ii)  a  carbon  tax,  which  would  impose  taxes  based  on  emissions  from  our  operations  and  the
downstream uses of our products. The “green new deal” calls for a 10-year national mobilization effort to, among other things, transition 100% of the U.S. power
demand to zero-emission sources and overhaul the U.S. transportation systems so that GHG emissions are eliminated as much as is technologically feasible. The
enactment of any such legislation would have a material adverse effect on our business and operations.

Our oil, natural gas and natural gas liquids are sold in a limited number of geographic markets so an oversupply in any of those areas could have a material
negative effect on the price we receive.

Our  oil,  natural  gas  and  natural  gas  liquids  are  primarily  sold  in  two  geographic  markets  in  Texas  which  each  have  a  fixed  amount  of  storage  and  processing
capacity. As a result, if such markets become oversupplied with oil, natural gas and/or natural gas liquids, it could have a material negative effect on the prices we
receive for our products and therefore an adverse effect on our financial condition and results of operations. There is a risk that refining capacity in the U.S. Gulf
Coast may be insufficient to refine all of the light sweet crude oil being produced in the United States. If light sweet crude oil production remains at current levels
or  continues  to  increase,  demand  for  our  light  crude  oil  production  could  result  in  widening  price  discounts  to  the  world  crude  prices  and  potential  shut-in  of
production due to a lack of sufficient markets despite the lift on prior restrictions on the exporting of oil and natural gas.

Potential  future  legislation  or  the  imposition  of  new  or  increased  taxes  or  fees  may  generally  affect  the  taxation  of  oil  and  natural  gas  exploration  and
development companies and may adversely affect our operations and cash flows.

In past years, federal and state level legislation has been proposed that would, if enacted into law, make significant changes to tax laws, including to certain key
federal and state income tax provisions currently available to oil and natural gas exploration and development companies. For example, President Biden has set
forth several tax proposals that would, if enacted into law, make significant changes to U.S. tax laws. Such proposals include, but are not limited to, (i) an increase
in  the  U.S.  income  tax  rate  applicable  to  corporations  and  (ii)  the  elimination  of  tax  subsidies  for  fossil  fuels.  Congress  could  consider  some  or  all  of  these
proposals in connection with tax reform to be undertaken by the Biden administration. It is unclear whether these or similar changes will be enacted and, if enacted,
how soon any such changes could take effect. Additionally, states in which we operate or own assets may impose new or increased taxes or fees on oil and natural
gas extraction. The passage of any

32

legislation as a result of these proposals and other similar changes in federal income tax laws or the imposition of new or increased taxes or fees on oil and natural
gas extraction could adversely affect our operations and cash flows.

Our operations are substantially dependent on the availability, use and disposal of water. New legislation and regulatory initiatives or restrictions relating to
water disposal wells could have a material adverse effect on our future business, financial condition, operating results and prospects.

Water is an essential component of our drilling and hydraulic fracturing processes. If we are unable to obtain water to use in our operations from local sources, we
may be unable to economically produce oil, natural gas and natural gas liquids, which could have an adverse effect on our business, financial condition and results
of  operations.  Wastewaters  from  our  operations  typically  are  disposed  of  via  underground  injection.  Some  studies  have  linked  earthquakes  in  certain  areas  to
underground  injection,  which  is  leading  to  greater  public  scrutiny  of  disposal  wells.  Any  new  environmental  initiatives  or  regulations  that  restrict  injection  of
fluids, including, but not limited to, produced water, drilling fluids and other wastes associated with the exploration, development or production of oil and gas, or
that limit the withdrawal, storage or use of surface water or ground water necessary for hydraulic fracturing of our wells, could increase our operating costs and
cause delays, interruptions or cessation of our operations, the extent of which cannot be predicted, and all of which would have an adverse effect on our business,
financial condition, results of operations and cash flows.

Any change to government regulation or administrative practices may have a negative impact on our ability to operate and our profitability.

Oil  and  natural  gas  operations  are  subject  to  substantial  regulation  under  federal,  state  and  local  laws  relating  to  the  exploration  for,  and  the  development,
upgrading, marketing, pricing, taxation, and transportation of, oil and natural gas and related products and other associated matters. Amendments to current laws
and regulations  governing  operations  and activities  of oil and natural  gas exploration  and development  operations  could have a material  adverse  impact  on our
business. In addition, there can be no assurance that income tax laws, royalty regulations and government programs related to our oil and natural gas properties and
the oil and natural gas industry generally will not be changed in a manner which may adversely affect our progress or cause delays.

Permits, leases, licenses, and approvals are required from a variety of regulatory authorities at various stages of exploration and development. There can be no
assurance that the various government permits, leases, licenses and approvals sought will be granted in respect of our activities or, if granted, will not be cancelled
or  will  be  renewed  upon  expiration.  There  is  no  assurance  that  such  permits,  leases,  licenses,  and  approvals  will  not  contain  terms  and  provisions  which  may
adversely affect our exploration and development activities.

The marketability of our production is dependent upon gathering systems, transportation facilities and processing facilities that we do not own or control. If
these facilities or systems are unavailable, our oil and natural gas production can be interrupted and our revenues reduced.

The  marketability  of  our  oil  and  natural  gas  production  is  dependent  upon  the  availability,  proximity  and  capacity  of  pipelines,  natural  gas  gathering  systems,
transportation and processing facilities owned by third parties. In general, we will not control these facilities, and our access to them may be limited or denied due
to  circumstances  beyond  our  control.  A  significant  disruption  in  the  availability  of  these  facilities  could  adversely  impact  our  ability  to  deliver  to  market  the
hydrocarbons  we  produce  and  thereby  cause  a  significant  interruption  in  our  operations.  In  some  cases,  our  ability  to  deliver  to  market  our  hydrocarbons  is
dependent upon coordination among third parties that own transportation and processing facilities we use, and any inability or unwillingness of those parties to
coordinate  efficiently  could  also  interrupt  our  operations.  The  lack  of  availability  or  the  lack  of  capacity  on  these  systems  and  facilities  could  result  in  the
curtailment of production or the delay or discontinuance of drilling plans. This is more likely in areas with recent increased production, such as our Permian Basin
area where we have significant development activities. These are risks for which we generally will not maintain insurance.

We operate or participate in oil and natural gas leases with third parties who may not be able to fulfill their commitments to our projects.

In some cases, we operate but own less than 100% of the working interest in the oil and natural gas leases on which we conduct operations, and other parties own
the remaining portion of the working interest. Financial risks are inherent in any operation where the cost of drilling, equipping, completing and operating wells is
shared by more than one person. We could be held liable for joint activity obligations of other working interest owners, such as nonpayment of costs and liabilities
arising from the actions of other working interest owners. In addition, declines in oil, natural gas and natural gas liquids prices may increase the likelihood that
some of these working interest owners, particularly those that are smaller and less established, are not able to fulfill their joint activity obligations. A partner may
be unable or unwilling to pay its share of project costs, and, in some cases, a partner may declare bankruptcy. In the event any of our project partners do not pay
their share of such costs, we would likely

33

have to pay those costs, and we may be unsuccessful in any efforts to recover these costs from our partners, which could materially adversely affect our financial
position.

Use of debt financing may adversely affect our strategy.

We may use debt to fund a portion of our future acquisition, development and/or operating activities. Any temporary or sustained inability to service or repay such
debt will likely have a material adverse effect on our ability to access financing markets and pursue our operating strategies, as well as impair our ability to respond
to adverse economic changes in oil and natural gas markets and the economy in general.

Because we cannot control activities on properties we do not operate, we cannot directly control the timing of exploitation. If we are unable to fund required
capital expenditures with respect to non-operated properties, our interests in those properties may be reduced or forfeited.

Our  ability  to  exercise  influence  over  operations  and  costs  for  the  properties  we  do  not  operate  is  limited.  Our  dependence  on  the  operator  and  other  working
interest owners for these projects and our limited ability to influence operations and associated costs could prevent the realization of our targeted returns on capital
with  respect  to  acquisition,  exploration  or  development  activities.  The  success  and  timing  of  development,  exploitation  or  exploration  activities  on  properties
operated by others depend upon a number of factors that may be outside our control, including but not limited to: the timing and amount of capital expenditures;
the operator’s expertise and financial resources; the approval of other participants in drilling wells; and the selection of technology.

Where  we  are  not  the  majority  owner  or  operator  of  a  particular  oil  and  natural  gas  project,  we  may  have  no  control  over  the  timing  or  amount  of  capital
expenditures  associated  with the project.  If  we are  not willing  or able  to fund required  capital  expenditures  relating  to a project  when required  by the  majority
owner(s) or operator, our interests in the project may be reduced or forfeited. Also, we could be responsible for plugging and abandonment costs, as well as other
liabilities in excess of our proportionate interest in the property.

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

The  oil  and  natural  gas  industry  has  become  increasingly  dependent  on  digital  technologies  to  conduct  day-to-day  operations  including  certain  exploration,
development and production activities. We are dependent on digital technologies including information systems and related infrastructure, to process and record
financial and operating data, communicate with our employees, business partners, and stockholders, analyze seismic and drilling information, estimate quantities of
oil and natural gas reserves as well as other activities related to our business.

As  dependence  on  digital  technologies  has  increased,  cyber  incidents,  including  deliberate  attacks  or  unintentional  events,  have  also  increased.  A  cyber-attack
could  include  gaining  unauthorized  access  to  digital  systems  for  the  purposes  of  misappropriating  assets  or  sensitive  information,  corrupting  data,  causing
operational disruption, or result in denial-of-service on websites.

Our technologies, systems, networks, and those of our business partners may become the target of cyber-attacks or information security breaches that could result
in the unauthorized release, gathering, monitoring, misuse, loss or destruction of proprietary and other information, or other disruption of our business operations.
In  addition,  certain  cyber  incidents,  such  as  surveillance,  may  remain  undetected  for  an  extended  period  of  time.  In  particular,  our  implementation  of  various
procedures  and  controls  to  monitor  and  mitigate  security  threats  and  to  increase  security  for  our  information,  data,  facilities  and  infrastructure  may  result  in
increased capital and operating costs. Costs for insurance may also increase as a result of security threats, and some insurance coverage may become more difficult
to obtain, if available at all. Moreover, there can be no assurance that such procedures and controls will be sufficient to prevent security breaches from occurring.
As cyber threats continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective measures or to
investigate  and remediate  any information  security  vulnerabilities.  A cyber incident  involving our information  systems and related  infrastructure,  or that of our
business partners, could disrupt our business plans and negatively impact our operations.

The loss or unavailability of any of our executive officers or other key employees could have a material adverse effect on our business.

We depend greatly on the efforts of our executive officers and other key employees to manage our operations. The loss or unavailability of any of our executive
officers or other key employees could have a material adverse effect on our business.

Risks Related to the Ownership of our Class A Common Stock

34

We are a holding company and the sole  manager of EEH. Our only material  asset is our equity  interest  in EEH and, accordingly, we are dependent  upon
distributions from EEH to cover our corporate and other overhead expenses and pay taxes.

We are a holding company and the sole manager of EEH. We have no material assets other than our equity interest in EEH. We have no independent means of
generating revenue. We expect EEH to reimburse us for our corporate and other overhead expenses, and to the extent EEH has available cash, we intend to cause
EEH to make distributions to the holders of membership units of EEH (“EEH Units”), including us, in an amount sufficient to cover all applicable U.S. federal,
state  and  local  income  taxes  and  non-U.S.  tax  liabilities  of  Earthstone,  Lynden  Corp  and  Lynden  US,  if  any,  at  assumed  tax  rates.  We  will  likely  be  limited,
however, in our ability to cause EEH and its subsidiaries to make these and other distributions due to the restrictions under the Credit Agreement. To the extent that
we need funds, and EEH or its subsidiaries are restricted from making such distributions under applicable law or regulation or under the terms of their financing
arrangements, or are otherwise unable to provide such funds, it could materially adversely affect our liquidity and financial condition.

Our principal stockholders hold substantial voting power of our Class A Common Stock and Class B Common Stock.

Holders of Class A Common Stock and our Class B Common Stock, $0.001 par value per share (“Class B Common Stock”), will vote together as a single class on
all matters presented to our stockholders for their vote or approval, except as otherwise required by applicable law or our Third Amended and Restated Certificate
of  Incorporation.  Subsequent  to  the  IRM  Acquisition,  EnCap  and  Warburg  Parties  may  be  deemed  to  beneficially  own  approximately  49.4%  and  17.0%,
respectively, of our voting interests and, along with their affiliates, could limit the ability of our other stockholders to approve transactions they may deem to be in
the best interests of our Company or delaying or preventing changes in control or changes in our management.

As long as EnCap and certain of its affiliates continue to control a significant amount of our outstanding voting securities, they will have the authority to exercise
significant  influence  over  management  and  all  matters  requiring  stockholder  approval,  regardless  of  whether  or  not  other  stockholders  believe  that  a  potential
transaction  is  in  their  own  best  interests.  Also,  in  any  of  these  matters,  the  interests  of  our  management  team  may  differ  or  conflict  with  the  interests  of  our
stockholders. In addition, EnCap and its affiliates may, from time to time, acquire interests in businesses that directly or indirectly compete with our business, as
well as businesses that are significant existing or potential acquisition candidates or industry partners. EnCap and its affiliates may acquire or seek to acquire assets
that  we  seek  to  acquire  and,  as  a  result,  those  acquisition  opportunities  may  not  be  available  to  us  or  may  be  more  expensive  for  us  to  pursue.  Moreover,  this
concentration  of  stock  ownership  may  also  adversely  affect  the  trading  price  of  our  Class  A  Common  Stock  to  the  extent  investors  perceive  a  disadvantage  in
owning stock of a company with a controlling stockholder.

Bold Holdings (controlled by EnCap) and its permitted transferees have the right to exchange their EEH Units and shares of Class B Common Stock for our
Class A Common Stock pursuant to the terms of the EEH LLC Agreement.

As of March 1, 2021, there were approximately 34.4 million shares of our Class A Common Stock that are issuable upon redemption or exchange of EEH Units
and shares of Class B Common Stock that are held by Bold Holdings, a fund managed by EnCap, or its permitted transferees. Pursuant to the First Amended and
Restated Limited Liability Company Agreement of EEH (the “EEH LLC Agreement”), subject to certain restrictions therein, holders of EEH Units and our Class B
Common  Stock  are  entitled  to  exchange  such  EEH  Units  and  shares  of  Class  B  Common  Stock  for  shares  of  our  Class  A  Common  Stock  at  any  time.  If  so
exercised, EnCap would own more than 50% of our Class A Common Stock and would therefore have the ability to control our Company.

Future sales of our Class A Common Stock in the public market, or the perception that such sales may occur, could reduce our stock price, and any additional
capital raised by us through the sale of equity may dilute your ownership in us.

We may sell additional shares of Class A Common Stock or securities convertible into shares of our Class A Common Stock in subsequent offerings. We cannot
predict the size of future issuances of our Class A Common Stock or securities convertible into Class A Common Stock or the effect, if any, that future issuances
and  sales  of  shares  of  our  Class  A  Common  Stock  will  have  on  the  market  price  of  our  Class  A  Common  Stock.  Sales  of  substantial  amounts  of  our  Class  A
Common Stock (including shares issued in connection with an acquisition), or the perception that such sales could occur, may adversely affect prevailing market
prices of our Class A Common Stock.

We have no plans to pay dividends on our Class A Common Stock. Stockholders may not receive funds without selling their shares.

We do not anticipate paying any cash dividends on our Class A Common Stock in the foreseeable future. We currently intend to retain future earnings, if any, to
finance the expansion of our business. In addition, the Credit Agreement does not allow EEH to

35

make any significant payments to us, which makes it highly unlikely that we would be in a position to pay cash dividends on our Class A Common Stock.

Our Board of Directors can, without stockholder approval, cause preferred stock to be issued on terms that could adversely affect our common stockholders.

Under our Third Amended and Restated  Certificate  of Incorporation,  our Board is authorized  to cause Earthstone  to issue up to 20,000,000 shares  of preferred
stock,  of  which  none  are  issued  and  outstanding  as  of  the  date  of  this  report.  Also,  our  Board,  without  stockholder  approval,  may  determine  the  price,  rights,
preferences, privileges, and restrictions, including voting rights, of those shares. If the Board causes shares of preferred stock to be issued, the rights of the holders
of our Class A Common Stock and Class B Common Stock would likely be subordinate to those of preferred holders and therefore could be adversely affected.
The  Board’s  ability  to  determine  the  terms  of  preferred  stock  and  to  cause  its  issuance,  while  providing  desirable  flexibility  in  connection  with  possible
acquisitions and other corporate purposes, could have the effect of making it more difficult for a third-party to acquire a majority of our outstanding voting stock or
otherwise seek to acquire us. Shares of preferred stock issued by us could include voting rights, or even super voting rights, which could shift the ability to control
Earthstone to the holders of the preferred stock. Preferred stock could also have conversion rights into shares of Class A Common Stock at a discount to the market
price of the Class A Common Stock which could negatively affect the market for our Class A Common Stock. In addition, preferred stock could have preference in
the  event  of  liquidation  of  Earthstone,  which  means  that  the  holders  of  preferred  stock  would  be  entitled  to  receive  the  net  assets  of  Earthstone  distributed  in
liquidation before the Class A common stockholders receive any distribution of the liquidated assets. We have no current plans to issue any shares of preferred
stock.

The price of our Class A Common Stock may fluctuate significantly, which could negatively affect us and holders of our Class A Common Stock.

The trading price of our Class A Common Stock may fluctuate significantly in response to a number of factors, many of which are beyond our control. Adverse
events including changes in production volumes, worldwide demand and prices for crude oil and natural gas, regulatory developments, and changes in securities
analysts’ estimates of our financial performance could negatively impact the market price of our Class A Common Stock. General market conditions, including the
level of, and fluctuations  in, the trading  prices of stocks generally  could also have a similar  negative  impact.  The stock markets  regularly  experience  price and
volume volatility that affects many companies’ stock prices without regard to the operating performance of those companies. Volatility of this type may affect the
trading price of our Class A Common Stock.

Anti-takeover provisions could make a third-party acquisition difficult.

Our Third Amended and Restated Certificate of Incorporation provides for a classified board of directors, with each member serving a three-year term. Provisions
in our Third Amended and Restated Certificate of Incorporation could make it more difficult for a third-party to acquire us without the approval of our Board. In
addition, the Delaware corporate statutes also contain certain provisions that could make an acquisition by a third-party more difficult.

Our stockholders may act by unilateral written consent.

Under our Third Amended and Restated Certificate of Incorporation, any action required to be taken at any annual or special meeting of our stockholders, or any
action which may be taken at any annual or special meeting of such stockholders, may be taken without a meeting, without prior notice and without a vote, if a
consent in writing, setting forth the action so taken, is signed by the holders of outstanding stock having not less than the minimum number of votes that would be
necessary  to  authorize  or  take  such  action  at  a  meeting  at  which  all  shares  entitled  to  vote  thereon  were  present  and  voted.  Thus,  consents  of  this  type  can  be
effected without the participation or input of minority stockholders.

Summary of Oil and Gas Properties

Midland Basin

As of December 31, 2020, we had approximately 27,900 net acres in the core of the Midland Basin that are highly contiguous on a project-by-project basis which
allow us to drill multi-well pads. Of this acreage, 78% is operated and 22% is non-operated. We hold an approximate 93% working interest in our operated acreage
and an approximate 40% working interest in our non-operated acreage. Our operated acreage in the Midland Basin, consisting of approximately 21,800 net acres, is
primarily located

36

in  Reagan,  Upton  and  Midland  counties.  Our  non-operated  acreage  in  the  Midland  Basin,  consisting  of  approximately  6,100  net  acres,  is  located  primarily  in
Howard, Glasscock, Martin, Midland and Reagan counties.

With  407  potential  gross  operated  horizontal  drilling  locations,  largely  de-risked,  the  vast  majority  of  which  are  in  various  benches  of  the  Wolfcamp  and  the
Spraberry formations, in the Midland Basin as of December 31, 2020, we are focused on developmental drilling and completion operations in the area. As a result
of  the  IRM  Acquisition,  we  added  43,400  additional  net  acres  in  the  Midland  Basin  of  which  99%  is  operated  and  1%  is  non-operated,  as  well  as  adding  70
potential  gross  horizontal  drilling  locations  on  core  acreage  located  in  Midland  and  Ector  counties.  We  continue  to  pursue  acreage  trades  or  bolt-on  acreage
acquisitions in the Midland Basin with the intent of increasing our operated acreage and drilling inventory, drilling and completing longer laterals and realizing
greater operating efficiencies.

During 2020, we completed and began producing from 9 gross / 9 net operated wells and 15 gross / 3.5 net non-operated wells. We exited 2020 with 5 gross / 3.7
net wells that were drilled and awaiting completion. We recently completed these wells and anticipate turning them to sales before the end of March 2021.

We recently commenced our 2021 drilling program with the deployment of a rig in Midland County. After drilling on a three-well pad in the Hamman project, we
expect  to  drill  a  four-well  pad  on  the  recently  acquired  IRM  Spanish  Pearl  project.  We  anticipate  moving  the  rig  to  Upton  County  and  drilling  10-11  wells.
Consistent with previously released guidance, we anticipate drilling 16 gross / 14.8 net operated wells and spudding an additional 5 gross / 3.7 net operated wells
during 2021.

Eagle Ford Trend

As  of  December  31,  2020,  we  held  approximately  26,400  gross  (12,500  net)  leasehold  acres  primarily  in  Fayette,  Gonzales  and  Karnes  counties,  Texas.  The
acreage is located in the crude oil window of the Eagle Ford shale trend of south Texas and is prospective for the Eagle Ford, Austin Chalk and Upper Eagle Ford
formations. Our working interests range from approximately 12% to 67%.

As of December 31, 2020, we operated 103 gross Eagle Ford wells and 12 gross Austin Chalk wells and had non-operated interests in five gross producing Eagle
Ford wells and one gross producing Austin Chalk wells. We have identified a total of 26 potential gross Eagle Ford drilling locations in this acreage. In addition,
because  our  acreage  position  is  prospective  for  the  Austin  Chalk  and  Upper  Eagle  Ford  formations,  we  may  have  additional  future  economic  locations.  The
majority of our acreage is covered by an approximately 173 square mile 3-D seismic survey.

Oil and Natural Gas Reserves

As  of  December  31,  2020,  all  of  our  oil  and  natural  gas  reserves  were  located  in  the  state  of  Texas.  We  expect  to  further  develop  these  properties  through
additional  drilling  and  completion  operations.  Our  reserve  estimates  have  been  prepared  by  Cawley,  Gillespie  &  Associates,  Inc.  (“CG&A”),  an  independent
petroleum engineering firm. The scope and results of CG&A’s procedures are summarized  in a letter which is included as an exhibit to this report. For further
information  on estimated  reserves,  including  information  on  estimated  future  net  cash  flows  and  the  standardized  measure  of  discounted  future  net  cash  flows,
please refer to the Supplemental Information on Oil and Gas Exploration and Production Activities (Unaudited) in Part II, Item 8 of the Notes to Consolidated
Financial Statements of this report.

As  of  December  31,  2020,  our  estimated  proved  reserves  totaled  78,875  MBOE  and  had  a  PV-10  value  of  approximately  $473.4  million  (reconciled  in  “Non-
GAAP Measures” below) and a Standardized Measure of Discounted Future Net Cash Flows of approximately $460.9 million, all of which relate to our properties
in Texas. We incurred approximately $66.8 million in capital expenditures, primarily drilling and completion costs, during 2020. We expect to further develop our
properties through additional drilling.

2020 Activity in Proved Reserves

From January 1, 2020 to December 31, 2020, our total estimated proved reserves decreased 16% from 94,336 MBOE to 78,875 MBOE. Of that, estimated proved
developed reserves increased 21% from 31,521 MBOE to 38,298 MBOE and estimated proved undeveloped reserves decreased 35% from 62,815 MBOE to 40,577
MBOE. The overall proved reserve decreases were primarily attributable to negative revisions due to price which included the reclassification of 11,913 MBOE of
reserves from proved undeveloped to non-proved due to the five-year development rule.

Proved Reserves as of December 31, 2020

The below table sets forth a summary of our estimated crude oil, natural gas and natural gas liquids reserves as of December 31, 2020, based on the annual reserve
estimate  prepared  by  CG&A.  In  preparing  this  reserve  report,  CG&A  evaluated  100%  of  our  properties  at  December  31,  2020.  The  prices  used  in  estimating
proved reserves are based on the unweighted arithmetic average

37

of the first-day-of-the-month price for each month within the 12-month period for the year. All prices and costs associated with operating wells were held constant
in accordance with the SEC guidelines.

Non-GAAP Measures

PV-10

PV-10  is  a  non-GAAP  measure  that  differs  from  a  measure  under  the  accounting  principles  generally  accepted  in  the  United  States  (“GAAP”)  known  as
“standardized  measure  of  discounted  future  net  cash  flows”  in  that  PV-10  is  calculated  without  including  future  income  taxes.  Management  believes  that  the
presentation of the PV-10 value of its oil and natural gas properties is relevant and useful to investors because it presents the estimated discounted future net cash
flows attributable to our estimated proved reserves independent of our income tax attributes, thereby isolating the intrinsic value of the estimated future cash flows
attributable to our reserves. We believe the use of a pre-tax measure provides greater comparability of assets when evaluating companies because the timing and
quantification of future income taxes is dependent on company-specific factors, many of which are difficult to determine. For these reasons, management uses and
believes  that  the  industry  generally  uses  the  PV-10  measure  in  evaluating  and  comparing  acquisition  candidates  and  assessing  the  potential  rate  of  return  on
investments in oil and natural gas properties. PV-10 does not necessarily represent the fair market value of oil and natural gas properties. PV-10 is not a measure of
financial or operational performance under GAAP, nor should it be considered in isolation or as a substitute for the standardized measure of discounted future net
cash flows as defined under GAAP.

The table below provides a reconciliation of PV-10 to the standardized measure of discounted future net cash flows (in thousands):

Free Cash Flow

$

$

473,409 
(12,556)
460,853 

Free cash flow is a measure that we use as an indicator of our ability to fund our development activities. We define free cash flow as Adjusted EBITDAX (defined
below), less interest expense, less accrual-based capital expenditures.

Adjusted EBITDAX

The non-GAAP financial measure of Adjusted EBITDAX, as calculated by us below, is intended to provide readers with meaningful information that supplements
our financial statements prepared in accordance with GAAP. Further, this non-GAAP measure should only be considered in conjunction with financial statements
and disclosures prepared in accordance with GAAP and should not be considered in isolation or as a substitute for GAAP measures, such as net income or loss,
operating income or loss or any other GAAP measure of financial position or results of operations. Adjusted EBITDAX is presented herein and

38

reconciled from the GAAP measure of net income because of its wide acceptance by the investment community as a financial indicator.

We define “Adjusted EBITDAX” as net income plus, when applicable, accretion of asset retirement obligations; impairment expense; depletion, depreciation and
amortization;  interest  expense,  net;  transaction  costs;  (gain)  on  sale  of  oil  and  gas  properties,  net;  exploration  expense;  unrealized  loss  (gain)  on  derivative
contracts; stock-based compensation (non-cash); and income tax benefit.

Our  Adjusted  EBITDAX  measure  provides  additional  information  that  may  be  used  to  better  understand  our  operations.  Adjusted  EBITDAX  is  one  of  several
metrics  that  we  use  as  a  supplemental  financial  measurement  in  the  evaluation  of  our  business  and  should  not  be  considered  as  an  alternative  to,  or  more
meaningful  than,  net  (loss)  income  as  an  indicator  of  operating  performance.  Certain  items  excluded  from  Adjusted  EBITDAX  are  significant  components  in
understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historic cost of depreciable
and  depletable  assets.  Adjusted  EBITDAX,  as  used  by  us,  may  not  be  comparable  to  similarly  titled  measures  reported  by  other  companies.  We  believe  that
Adjusted EBITDAX is a widely followed measure of operating performance and is one of many metrics used by our management team and by other users of our
consolidated financial statements. For example, Adjusted EBITDAX can be used to assess our operating performance and return on capital in comparison to other
independent exploration and production companies without regard to financial or capital structure and to assess the financial performance of our assets and our
Company without regard to capital structure or historical cost basis.

Reserve Quantity Information

The  following  table  illustrates  our  estimated  net  proved  reserves,  including  changes,  and  proved  developed  and  proved  undeveloped  reserves  for  the  periods
indicated. The oil prices as of December 31, 2020 and 2019, are based on the respective 12-month unweighted average of the first of the month prices of the WTI
spot  prices  which  equates  to  $39.57  per  barrel  and  $55.69  per  barrel,  respectively.  The  natural  gas  prices  as  of  December  31,  2020  and  2019  are  based  on  the
respective  12-month  unweighted  average  of  the  first  of  month  prices  of  the  Henry  Hub  spot  price  which  equates  to  $1.99  per  MMBtu  and  $2.58  per  MMBtu,
respectively.  The  natural  gas  liquids  prices  used  to  value  reserves  as  of  December  31,  2020  and  2019  averaged  $11.61  per  barrel  and  $16.17  per  barrel,
respectively. All prices are adjusted by lease or field for energy content, transportation fees, and market differentials, resulting in the aforementioned oil, natural
gas and natural gas liquids reserves as of December 31, 2020 being valued using prices of $38.90 per barrel, $0.97 per MMBtu and $11.61 per barrel, respectively.
All prices are held constant in accordance with SEC guidelines.

Notable changes in proved reserves for the year ended December 31, 2020 included the following:

•

•

Extensions  and  discoveries. In  2020,  total  extensions  and  discoveries  of  860.0  MBOE  was  the  result  of  successful  drilling  results  and  well
performance primarily related to the Midland Basin.

Revision  to  previous  estimates. In  2020,  the  downward  revisions  of  prior  reserves  of  10.7  MMBOE  were  primarily  attributable  to  negative
revisions due to price which included the reclassification of 11.9 MMBOE of reserves from proved undeveloped to non-proved due to the five-
year development rule.

Notable changes in proved reserves for the year ended December 31, 2019 included the following:

•

•

•

Extensions  and  discoveries. In  2019,  total  extensions  and  discoveries  of  5.1  MMBOE  was  a  result  of  successful  drilling  results  and  well
performance primarily related to the Midland Basin. 

Sales of minerals in place. Sales of minerals in place totaled  32.0 MBOE during 2019, resulting from the disposition  of certain  non-operated
properties in the Midland Basin. See Note 3. Acquisitions and Divestitures in the Notes to Consolidated Financial Statements.    

Revision to previous estimates. In 2019, the downward revisions of prior reserves  of 4.6 MMBOE were primarily  due to reduced commodity
prices.

Proved Undeveloped Reserves

Proved undeveloped reserves (“PUDs”) decreased from 62,815 MBOE to 40,577 MBOE or 35%, as of December 31, 2020 compared to December 31, 2019. PUDs
represent  51%  of  our  total  proved  reserves.  Certain  previously  booked  PUDs  were  reclassified  as  proved  developed  reserves  due  to  successful  drilling  efforts.
Revisions of prior estimates include certain PUDs that were reclassified to unproved categories due to development plan changes and increased well spacing. In
accordance with our December 31, 2020 year-end independent engineering reserve report, we plan to drill all of our individual PUD drilling locations within the
five years of original classification.

Changes in our PUD reserves for the years ended December 31, 2020 and 2019 were as follows (in MBOE):

2020 Changes in Proved Undeveloped Reserves

Conversions to developed. In our year-end 2019 plan to develop its PUDs within five years, we estimated that $111.1 million of capital would be expended in 2020
for the conversion of 28 gross / 17.6 net PUDs to add 11.3 MMBOE. In 2020, due to unforeseeable conditions described above, we spent $67.8 million to convert
18 gross / 10.3 net PUDs adding 8.2 MMBOE to developed reserves.

Revision to previous estimates. We maintain a five-year development plan, reviewed annually to ensure capital is allocated to the wells that have the highest risk-
adjusted rates of return within our inventory of undrilled well locations. In response to lower commodity prices, we reduced the pace of activity in our five-year
development plan. This resulted in the reclassification of 11.9 MMBOE of reserves from proved undeveloped to non-proved during the year ended December 31,
2020 due to the five-year development rule. Based on our then-current acreage position, strip prices, anticipated well economics, and our development plans at the
time  these  reserves  were  classified  as  proved,  we  believe  the  previous  classification  of  these  locations  as  proved  undeveloped  was  appropriate.  The  remaining
revisions of 2.1 MMBOE were primarily due to reduced commodity prices.

2019 Changes in Proved Undeveloped Reserves

Conversions to developed. In our year-end 2018 plan to develop our PUDs within five years, we estimated that $103.8 million of capital would be expended in
2019 for the conversion of 30 gross / 12.3 net PUDs to add 9.9 MMBOE, which was consistent with the $111.5 million actually spent to convert 32 gross / 13.4 net
PUDs adding 10.3 MMBOE to developed reserves.

Extensions and discoveries. Additionally, 1.2 MMBOE were added as extensions and discoveries due to successful drilling results on our acreage positions because
of the wells we drilled. The increase was also supported by successful drilling results by other operators directly offsetting and in close proximity to our acreage.

Revision to previous estimates. Revisions of 3.4 MMBOE were primarily due to reduced commodity prices.

Beginning  in  2021  and  thereafter,  the  production  and  cash  flows  represent  the  drilling  results  from  the  respective  year  plus  the  incremental
effects from the results of proved undeveloped drilling from previous years. These production volumes, inflows, expenses, development costs
and cash flows are limited to the PUD reserves and do not include any production or cash flows from the Proved Developed category which will
also help to fund our capital program.

Barrels of oil equivalent have been calculated on the basis of six thousand cubic feet (Mcf) of natural gas equal to one barrel of oil equivalent
(BOE).

Computation is based on SEC pricing of (i) $38.90 per Bbl (WTI-Cushing oil spot prices, adjusted for differentials), (ii) $0.97 per Mcf (Henry
Hub spot natural gas price), as adjusted for location and quality by property and (iii) $11.61 per Bbl for natural gas liquids.

PUD reserves are expected to be recovered from new wells on undrilled acreage or from existing wells where additional capital expenditures are required, such as
from drilled but uncompleted (DUC) wells. Our development plan contemplates production to commence from all these wells by 2024.

Historically, our drilling programs have been substantially funded from our cash flow and borrowings under our Credit Agreement. Based on current commodity
prices and our current expectations over the next five years of our cash flows and

41

 
drilling  programs,  which  includes  drilling  of  proved  undeveloped  and  unproven  locations,  we  believe  that  we  can  continue  to  substantially  fund  our  drilling
activities from our cash flow and with borrowings under the Credit Agreement. 

Preparation of Reserve Estimates

We engaged an independent petroleum engineering consulting firm, CG&A, to prepare our annual reserve estimates and we have relied on CG&A’s expertise to
ensure that our reserve estimates are prepared in compliance with SEC guidelines.

The technical person primarily responsible for the preparation of the reserve report is Mr. W. Todd Brooker, President of CG&A. He graduated with honors from
the University of Texas at Austin in 1989 with a Bachelor of Science degree in Petroleum Engineering. Mr. Brooker is a Registered Professional Engineer in the
State of Texas (License No. 83462) and has more than 25 years of experience in the estimation and evaluation of oil and natural gas reserves. He is also a member
of the Society of Petroleum Engineers.

Geoffrey A. Vernon, our Vice President of Reservoir Engineering and A&D, is responsible for reservoir engineering, is a qualified reserve estimator and auditor
and  is  primarily  responsible  for  overseeing  CG&A  during  the  preparation  of  our  annual  reserve  estimates.  His  professional  qualifications  meet  or  exceed  the
qualifications of reserve estimators and auditors set forth in the “Standards Pertaining to Estimation and Auditing of Oil and Natural Gas Reserves Information”
promulgated by the Society of Petroleum Engineers. His qualifications include a Bachelor of Science degree in Chemical Engineering from Texas Tech University
in 2007; a Master of Business Administration degree from Rice University in 2014; member of the Society of Petroleum Engineers since 2007; and more than 13
years  of practical  experience  in  estimating  and  evaluating  reserve  information  with  more  than  nine of  those  years  being in  charge  of  estimating  and  evaluating
reserves.

We maintain adequate and effective internal controls over our reserve estimation process as well as the underlying data upon which reserve estimates are based.
The  primary  inputs  to  the  reserve  estimation  process  are  technical  information,  financial  data,  ownership  interest  and  production  data.  The  relevant  field  and
reservoir technical information, which is updated, at least, annually, is assessed for validity when CG&A has technical meetings with our engineers, geologists,
operations and land personnel. Current revenue and expense information is obtained from our accounting records, which are subject to external quarterly reviews,
annual audits and our own set of internal controls over financial reporting. Internal controls over financial reporting are assessed for effectiveness annually using
criteria set forth in Internal Control – Integrated Framework, (2013 Version) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
All current financial data such as commodity prices, lease operating expenses, production taxes and field level commodity price differentials are updated in the
reserve database and then analyzed to ensure that they have been entered accurately and that all updates are complete. Our current ownership in mineral interests
and well production data are also subject to our internal controls over financial reporting, and they are incorporated in our reserve database as well and verified
internally  by  our  personnel  to  ensure  their  accuracy  and  completeness.  Once  the  reserve  database  has  been  updated  with  current  information,  and  the  relevant
technical support material has been assembled, CG&A meets with our technical personnel to review field performance and future development plans in order to
further verify the validity of estimates. Following these reviews, the reserve database is furnished to CG&A so that it can prepare its independent reserve estimates
and final report. The reserve estimates prepared by CG&A are reviewed and compared to our internal estimates by our Vice President of Reservoir Engineering
and A&D. Material reserve estimation differences are reviewed between CG&A and us, and additional data is provided to address the differences. If the supporting
documentation  will  not  justify  additional  changes,  the  CG&A reserves  are  accepted.  In  the  event  that  additional  data  supports  a  reserve  estimation  adjustment,
CG&A will analyze the additional data, and may make changes it solely deems necessary. Additional data is usually comprised of updated production information
on new wells. Once the review is completed and all material differences are reconciled, the reserve report is finalized and our reserve database is updated with the
final estimates provided by CG&A.

Overview

We are a growth-oriented independent oil and gas company engaged in the economic acquisition and development of oil and gas reserves through activities that
include the acquisition, drilling and development of undeveloped leases, asset and corporate

46

 
 
 
acquisitions and mergers. Our operations are all in the upstream segment of the oil and natural gas industry and all our properties are onshore in the United States.
At present, our assets are located in the Midland Basin of west Texas and the Eagle Ford Trend of south Texas.

Earthstone is the sole managing member of Earthstone Energy Holdings, LLC, a Delaware limited liability company (together with its wholly-owned consolidated
subsidiaries, “EEH”), with a controlling interest in EEH. Earthstone, together with its wholly-owned subsidiary, Lynden Corp, and Lynden Corp’s wholly-owned
consolidated subsidiary, Lynden US and also a member of EEH, consolidates the financial results of EEH and records a noncontrolling interest in the Consolidated
Financial Statements representing the economic interests of EEH’s members other than Earthstone and Lynden US (collectively, the “Company” “our,” “we,” “us,”
or similar terms).

Midland Basin Acquisition

On  January  7,  2021,  Earthstone  Energy,  Inc.  (“Earthstone”  or  the  “Company”),  Earthstone  Energy  Holdings,  LLC,  a  subsidiary  of  the  Company  (“EEH”  and
collectively  with  Earthstone,  the  “Buyer”),  Independence  Resources  Holdings,  LLC  (“Independence”),  and  Independence  Resources  Manager,  LLC
(“Independence  Manager”  and  collectively  with  Independence,  the  “Seller”)  consummated  the  transactions  contemplated  in  the  Purchase  and  Sale  Agreement
dated  December  17,  2020  (the  “Purchase  Agreement”)  that  was  previously  reported  on  Form  8-K  filed  with  the  SEC  on  December  22,  2020.  The  Seller  was
unaffiliated with the Company. At the closing of the Purchase Agreement, among other things, EEH acquired (the “Acquisition”) all of the issued and outstanding
limited  liability  company  interests  in  certain  wholly  owned  subsidiaries  of  Independence  and  Independence  Manager  (collectively,  the  “Acquired  Entities”)  for
aggregate consideration consisting of the following: (i) an aggregate amount of cash from EEH equal to approximately $131.2 million (the “Cash Consideration”)
and (ii) 12,719,594 shares of the Company’s Class A Common Stock issued to Independence (such shares, the “Acquisition Shares,” and such issuance, the “Stock
Issuance”). As a result of the Stock Issuance, Earthstone is no longer considered a controlled company within the meaning of the NYSE rules.

Amendment to Credit Agreement - In preparation for the IRM Acquisition, on December 17, 2020, Earthstone, EEH, as Borrower, Wells Fargo Bank, National
Association (“Wells Fargo”), as Administrative Agent, the guarantors party thereto, and the lenders party thereto (the “Lenders”) entered into an amendment (the
“Amendment”) to the credit agreement dated November 21, 2019, by and among EEH, as Borrower, Earthstone, as Parent, Wells Fargo, as Administrative Agent
and Issuing Bank, BOKF, NA dba Bank of Texas, as Issuing Bank with respect to Existing Letters of Credit, Royal Bank of Canada, as Syndication Agent, Truist
Bank, as successor by merger to SunTrust Bank, as Documentation Agent, and the Lenders party thereto (together with all amendments or other modifications, the
“Credit Agreement”). The Amendment was effective upon the closing of the IRM Acquisition. Among other things, the Amendment (i) joined certain financial
institutions as additional lenders, increased the borrowing base from $240.0 million to $360.0 million, (ii) increased the interest rate on outstanding borrowings;
and (iii) adjusted some of the financial covenants.

Liquidity Update

As of March 1, 2021, we had $10.1 million in cash and $227.5 million of long-term debt outstanding under our Credit Agreement, as amended, with a borrowing
base  of  $360  million.  With  the  $132.5  million  of  undrawn  borrowing  base  capacity  and  $10.1  million  in  cash,  we  had  total  liquidity  of  approximately  $142.6
million.

Areas of Operation

At  present,  our  primary  efforts  are  concentrated  in  the  Midland  Basin  of  west  Texas,  a  high  oil  and  liquids  rich  resource  basin  that  provides  us  with  multiple
horizontal targets, extensive production histories, long-lived reserves and historically high drilling success rates.  

Midland Basin

We believe that the Midland Basin continues to have attractive economics and we expect to continue growing our footprint through development drilling, acreage
trades, asset acquisitions, and corporate merger and acquisition opportunities.

We  continue  to  be  active  in  acreage  trades  and  acquisitions  in  the  Midland  Basin  which  generally  allow  for  longer  laterals,  increased  operated  inventory  and
greater operating efficiency.

During 2020, we completed and began producing from 9 gross / 9 net operated wells and 15 gross / 3.5 net non-operated wells. We exited 2020 with 5 gross / 3.7
net wells that were drilled and awaiting completion. We recently completed these wells and anticipate turning them to sales before the end of March 2021.

We recently commenced our 2021 drilling program with the deployment of a rig in Midland County. After drilling on a three-well pad in the Hamman project, we
expect to drill a four-well pad on the recently acquired IRM Spanish Pearl project. We

47

anticipate  moving  the  rig  to  Upton  County  and  drilling  10-11  wells.  Consistent  with  previously  released  guidance,  we  anticipate  drilling  16  gross  /  14.8  net
operated wells and spudding an additional 5 gross / 3.7 net operated wells during 2021.

Additionally, we are focused on efficiently integrating the recently acquired IRM assets into our operations. As a result of the IRM Acquisition, we added 43,400
additional net acres in the Midland Basin of which 99% is operated and 1% is non-operated, as well as adding 70 potential gross horizontal drilling locations on
core acreage located in Midland and Ector counties.

Oil revenues

For  the  year  ended  December  31,  2020,  oil  revenues  decreased  by approximately  $51.6  million  or  30%  compared  to  2019.  Of the  decrease,  $55.1 million  was
attributable to lower realized prices, partially offset by $3.5 million due to increased sales volumes. Our average realized price per Bbl decreased from $55.71 for
the year ended December 31, 2019 to $37.85 or 32% for the year ended December 31, 2020. We had a net increase in the volume of oil sold of 93 MBbls or 3%,
primarily due to new wells brought online offset by production shut-ins we initiated in May 2020 due to the domestic collapse of oil prices.

Natural gas revenues

For the year ended December 31, 2020, natural gas revenues increased by $4.7 million or 119% compared to 2019. Of the increase, $3.0 million was attributable to
increased  sales  volumes  and  $1.7  million  was  due  to  higher  realized  prices.  Our  average  realized  price  per  Mcf  increased  43%  from  $0.82  for  the  year  ended
December 31, 2019 to $1.18 for the year ended December 31, 2020. In the prior year, lack of sufficient pipeline transportation resulted in low natural gas prices,
which improved in 2020. The total volume of natural gas produced and sold increased 2,522 MMcf or 53% primarily due to new wells brought online offset by the
production shut-ins we initiated in May 2020.

Natural gas liquids revenues

For the year ended December 31, 2020, natural gas liquids revenues were relatively flat as compared to 2019 as a $2.3 million increase attributable to higher sales
volumes was mostly offset by a $2.1 million decrease due to lower realized prices. The volume of natural gas liquids produced and sold increased by 176 MBbls or
17%, primarily due to new wells brought online offset by voluntary production shut-ins in May 2020.

Lease operating expense (“LOE”)

LOE includes all costs incurred to operate wells and related facilities for both operated and non-operated properties. In addition to direct operating costs such as
labor, repairs and maintenance, re-engineering and workovers, equipment rentals, materials and supplies, fuel and chemicals, LOE includes product marketing and
transportation fees, insurance and overhead charges provided for in operating agreements.

LOE remained relatively flat, increasing by $0.4 million or 2% for the year ended December 31, 2020 compared to 2019, primarily due to costs reduction efforts
implemented during 2020, offset by increased production in 2020.

Production and ad valorem taxes

Production and ad valorem taxes for the year ended December 31, 2020 decreased by $2.5 million or 21% compared to 2019, as the impact of increased volume
was more than offset by the impact of decreased commodity prices. As a percentage of revenues from oil, natural gas, and natural gas liquids, production taxes
remained relatively flat in 2020 compared to the prior year.

Impairment

During the year ended December 31, 2020, we recorded non-cash impairments totaling $64.5 million which consisted of $25.3 million to proved oil and natural gas
properties, $21.6 million to unproved oil and natural gas properties and $17.6 million to goodwill. No impairments were recorded during the year ended December
31, 2019. See Note 7. Oil and Natural Gas Properties in the Notes to Consolidated Financial Statements for a discussion of how impairments are measured.

Depreciation, depletion and amortization (“DD&A”)

DD&A increased for the year ended December 31, 2020 by $27.2 million, or 39% compared to 2019, primarily due to reserve reductions resulting from depressed
commodity  prices  (lower  reserve  quantities  leads  to  higher  DD&A  per  Boe),  partially  offset  by  a  first  quarter  2020  impairment  charge  of  $25.3  million  which
resulted in a decreased depletable oil and natural gas properties base.

General and administrative expense (“G&A”)

These expenses consist primarily of employee remuneration, professional and consulting fees and other overhead expenses. G&A increased by $0.6 million for the
year ended December 31, 2020 relative to the comparable period in 2019, primarily due to a $1.4 million increase in non-cash stock-based compensation expense
related to awards granted in January 2020, offset by $0.8 million in reductions in cash-based expenses resulting from cost reduction efforts implemented in 2020.

50

 
Transaction costs

During the year ended December 31, 2020, we recorded transaction costs primarily due to legal, consulting and other fees of approximately $1.0 million related to
the business combination which was consummated on January 7, 2021 and $0.3 million related to other potential transactions, offset by net reimbursements of $0.7
million related  to the business combination  (the “Bold Transaction”)  pursuant to the Bold Contribution Agreement (as defined below) which closed on May 9,
2017.  During  the  year  ended  December  31,  2019,  the  Company  recorded  transaction  costs  totaling  approximately  $1.1  million  primarily  due  to  the  Bold
Transaction.

Gain on sale of oil and gas properties, net

During the years ended December 31, 2020 and 2019, we sold certain oil and gas properties located in the Midland Basin, recording gains totaling $0.2 million and
$3.6 million, respectively. See Note 3. Acquisitions and Divestitures in the Notes to Consolidated Financial Statements.

Interest expense, net

Interest expense includes commitment  fees, amortization  of deferred financing costs, and interest on outstanding indebtedness. Interest expense decreased from
$6.6 million for the year ended December 31, 2019, to $5.2 million for the year ended December 31, 2020 primarily due to lower effective interest rates, as well as
lower outstanding borrowings compared to the prior year. See Note 13. Long-Term Debt in the Notes to Consolidated Financial Statements.

Write-off of deferred financing costs

During  the  year  ended  December  31,  2019,  in  connection  with  the  termination  of  the  prior  credit  agreement,  $1.2  million  of  remaining  unamortized  deferred
financing costs were expensed and included in Write-off of deferred financing costs in the Consolidated Statements of Operations. See Note 13. Long-Term Debt in
the Notes to Consolidated Financial Statements.

Gain (loss) on derivative contracts, net

For the year ended December 31, 2020, we recorded a net gain on derivative contracts of $59.9 million, consisting of net realized gains on settlements of $56.0
million  and  unrealized  mark-to-market  gains  of  $3.9  million.  For  the  year  ended  December  31,  2019,  we  recorded  a  net  loss  on  derivative  contracts  of  $44.0
million, consisting of unrealized mark-to-market losses of $59.8 million, partially offset by net realized gains on settlements of $15.9 million.

Income tax benefit (expense)

During the year ended December 31, 2020, the Company recorded total income tax benefit of $0.11 million which included (1) deferred income tax expense for
Lynden US of $0.15 million as a result of its share of the distributable income from EEH, (2) deferred income tax benefit for Earthstone of $0.61 million as a result
of its share of the distributable loss from EEH, which was offset by a valuation allowance as future realization of the net deferred tax asset cannot be assured and
(3) current income tax expense of $0.55 million, offset by deferred income tax benefit of $0.51 million related to the Texas Margin Tax. Lynden Corp incurred no
material income or loss, or related income tax expense or benefit, for the year ended December 31, 2020.  

During the year ended December 31, 2019, the Company recorded a total income tax expense of $1.7 million which included (1) deferred income tax expense for
Lynden US of $0.1 million as a result of its share of the distributable income from EEH, (2) deferred income tax expense for Earthstone of $0.4 million as a result
of its share of the distributable income from EEH, which was used to reduce the valuation allowance recorded against its deferred tax asset as future realization of
the  net  deferred  tax  asset  cannot  be  assured  and  (3)  deferred  income  tax  expense  of  $1.6  million  related  to  the  Texas  Margin  Tax.  Lynden  Corp  incurred  no
material income or loss, or related income tax expense or benefit, for the year ended December 31, 2019.

Liquidity and Capital Resources

We have significant undeveloped acreage and future drilling locations. Drilling horizontal wells, generally consisting of 7,500 to 12,000-foot lateral lengths, in the
Midland  Basin  is  capital  intensive.  As  of  December  31,  2020,  we  had  $1.5  million  in  cash  and  $115  million  of  long-term  debt  outstanding  under  our  Credit
Agreement with a borrowing base of $240 million. With the $125 million of undrawn borrowing base capacity and $1.5 million in cash, we had total liquidity of
approximately $126.5 million. Subsequent to year-end, Earthstone closed on its previously announced acquisition of IRM and amended the Credit Agreement. As
of March 1, 2021, we had $10.1 million in cash and $227.5 million of long-term debt outstanding under our Credit Agreement, as amended, with a borrowing base
of $360 million. With the $132.5 million of undrawn borrowing base capacity and $10.1 million in cash, we had total liquidity of approximately $142.6 million.

51

As oil prices have recovered recently from their 2020 lows, we are preparing to resume drilling operations with the deployment of a rig late in the first quarter of
2021  and  we  expect  to  spend  $90-$100  million  based  on  our  current  2021  drilling  plan.  We  believe  we  will  have  sufficient  liquidity  with  cash  flows  from
operations and borrowings under the Credit Agreement to meet our cash requirements for the next 12 months.

Working Capital

Working  Capital  (presented  below)  was  a  deficit  of  $20.8  million  as  of  December  31,  2020  compared  to  a  deficit  of  $39.9  million  as  of  December  31,  2019,
representing  an  improvement  of  $19.2  million.  The  improvement  was  primarily  due  to  the  reduction  of  liabilities  resulting  from  reduced  drilling  activity.  The
components of working capital are presented below:

Current assets:

Cash

(39,890)

We expect that changes in receivables and payables related to our pace of development, production volumes, changes in our hedging activities, realized commodity
prices and differentials to NYMEX prices for our oil and natural gas production will continue to be the largest variables affecting our working capital.

We  expect  to  finance  future  development  activities  with  cash  flows  from  operating  activities,  borrowings  under  the  Credit  Agreement  and,  various  means  of
corporate  and  project  financing.  Additionally,  we  may  continue  to  partially  finance  our  drilling  activities  through  the  sale  of  participating  rights  to  financial
institutions  or  industry  participants,  and  we  could  structure  such  arrangements  on  a  promoted  basis,  whereby  we  may  earn  working  interests  in  reserves  and
production greater than our proportionate share of capital costs.

In July 2019, we entered into a Wellbore Development Agreement (“WDA”) with a non-affiliated industry partner. This WDA reduced our working interest in
certain wells in Reagan County. The industry partner paid a promoted (proportionately higher) share of the capital expenditures on eight wells, to earn 35% of the
working interest in these wells.

2021 amount represents interest payable under the Credit Agreement as of December 31, 2020. 
We have a non-cancelable fixed cost agreement of $0.7 million per year through May 2021 to reserve pipeline capacity of 10,000 MMBtu per
day for gathering and processing related to certain Eagle Ford assets in south Texas. As the operator of the properties dedicated to this contract,
the gross amount of obligation is provided; however, our net share is approximately 31%.

On January 7, 2021, upon closing of the IRM Acquisition, EEH became party to an office lease with an effective termination date of May 31, 2021, for which the
remaining obligation is approximately $0.26 million.

Environmental Regulations

Our  operations  are  subject  to  risks  normally  associated  with  the  exploration  for  and  the  production  of  oil  and  natural  gas,  including  blowouts,  fires,  and
environmental risks such as oil spills or natural gas leaks that could expose us to liabilities associated with these risks.

In our acquisition of existing or previously drilled well bores, we may not be aware of prior environmental safeguards, if any, that were taken at the time such wells
were drilled or during such time the wells were operated. We maintain comprehensive insurance coverage that we believe is adequate to mitigate the risk of any
adverse financial effects associated with these risks.

However, should it be determined that a liability exists with respect to any environmental cleanup or restoration, the liability to cure such a violation could still
accrue to us. No claim has been made, nor are we aware of any liability which we may have, as it relates to any environmental cleanup, restoration, or the violation
of any rules or regulations relating thereto.

Critical Accounting Policies and Estimates

Our discussion of financial condition and results of operations is based upon the information reported in our consolidated financial statements. The preparation of
these statements requires us to make certain assumptions and estimates that affect the reported amounts of assets, liabilities, revenues and expenses as well as the
disclosure  of contingent  assets and liabilities  at the  date of our financial  statements.  We base our assumptions and estimates  on historical  experience  and other
sources  that  we  believe  to  be  reasonable  at  the  time.  Actual  results  may  vary  from  our  estimates  due  to  changes  in  circumstances,  weather,  politics,  global
economics, mechanical problems, general business conditions and other risks. We have outlined below certain of these policies as being of particular importance to
the portrayal of our financial position and results of operations and which require the application of significant judgment by our management.

Oil and Natural Gas Properties

We  use  the  successful  efforts  method  of  accounting  for  oil  and  natural  gas  operations.  Under  this  method,  costs  to  acquire  oil  and  natural  gas  properties,  drill
successful  exploratory  wells,  drill  and  equip  development  wells,  and  install  production  facilities  are  capitalized.  Exploration  costs,  including  unsuccessful
exploratory wells, geological and geophysical are charged to operations as incurred. Depreciation, depletion and amortization of the leasehold and development
costs  that  are  capitalized  for  proved  oil  and  natural  gas  properties  are  computed  using  the  units-of-production  method,  at  the  field  level,  based  on  total  proved
reserves and proved developed reserves, respectively, as estimated by independent petroleum engineers. Oil and natural gas properties are periodically assessed for
impairment whenever changes in facts and circumstances indicate a possible significant deterioration in the future cash flows expected to be generated by an asset
group, but at least annually. Individual assets are grouped for impairment purposes at the lowest level for which there are identifiable cash flows that are largely
independent of the cash flows of other groups of assets, generally on a field-by-field basis. All of our properties are located within the continental United States.

Oil and Natural Gas Reserve Quantities

Reserve quantities and the related estimates of future net cash flows affect our periodic calculations of depletion, impairment of our oil and natural gas properties,
and asset retirement obligations. Proved oil and natural gas reserves are the estimated quantities of oil, natural gas and natural gas liquids which geological and
engineering  data  demonstrate  with  reasonable  certainty  to  be  recoverable  in  future  periods  from  known  reservoirs  under  existing  economic  and  operating
conditions. Reserve quantities and future cash flows included in this report are prepared in accordance with guidelines established by the SEC and the Financial
Accounting Standards Board (“FASB”). The accuracy of our reserve estimates is a function of:

•

•

•

•

The quality and quantity of available data;

The interpretation of that data;

The accuracy of various mandated economic assumptions; and

The judgments of the persons preparing the estimates.

Our  proved  reserves  information  included  in  this  report  is  based  on  estimates  prepared  by  our  independent  petroleum  engineers,  CG&A.  The  independent
petroleum  engineers  evaluated  100%  of  our  estimated  proved  reserve  quantities  and  their  related  future  net  cash  flows  as  of  December  31,  2020.  Estimates
prepared by others may be higher or lower than our estimates. Because these estimates depend on many assumptions, all of which may differ substantially from
actual results, reserve estimates may be different from the quantities of oil and natural gas that are ultimately recovered. We make revisions to reserve estimates
throughout the year as additional information becomes available. We make changes to depletion rates, impairment calculations, and asset retirement obligations in
the same period that changes to reserve estimates are made.

Depreciation, Depletion and Amortization

Our rate of recording DD&A is dependent upon our estimates of total proved and proved developed reserves, which estimates incorporate various assumptions and
future projections. If the estimates of total proved or proved developed reserves decline, the rate at which we record DD&A expense increases, reducing our net
income. Such a decline in reserves may result from lower commodity prices, which may make it uneconomic to drill for and produce higher cost fields. We are
unable to predict changes in reserve quantity estimates as such quantities are dependent on the success of our exploitation and development program, as well as
future economic conditions.

Impairment of Oil and Natural Gas Properties

We review the value of our oil and natural gas properties whenever management judges that events and circumstances indicate that the recorded carrying value of
properties may not be recoverable. Impairments of producing properties are determined by comparing the pretax future net undiscounted cash flows to the net book
value at the end of each period. If the net capitalized cost exceeds undiscounted future cash flows, the cost of the property is written down to “fair value,” which is
determined based on expected future cash flows using discount rates commensurate with the risks involved, using prices and costs consistent with those used for
internal  decision  making.  Different  pricing  assumptions  or  discount  rates  could  result  in  a  different  calculated  impairment.  We  provide  for  impairments  on
significant undeveloped properties when we determine that the property will not be developed or a permanent impairment in value has occurred.

Asset Retirement Obligation

Our asset retirement obligations (“AROs”) consist primarily of estimated future costs associated with the plugging and abandonment of oil and natural gas wells,
removal of equipment and facilities from leased acreage, and land restoration in accordance with applicable local, state and federal laws. The discounted fair value
of an ARO liability is required to be recognized in the period in which it is incurred, with the associated asset retirement cost capitalized as part of the carrying cost
of  the  oil  and  natural  gas  asset.  The  recognition  of  an  ARO  requires  that  management  make  numerous  assumptions  regarding  such  factors  as  the  estimated
probabilities,  amounts  and  timing  of  settlements;  the  credit-adjusted  risk-free  rate  to  be  used;  inflation  rates;  and  future  advances  in  technology.  In  periods
subsequent to the initial measurement of the ARO, we must recognize period-to-period changes in the liability resulting from the passage of time and revisions to
either the timing or the amount of the original estimate of undiscounted cash flows. Increases in the ARO liability due to passage of time impact net income as
accretion expense. The related capitalized cost, including revisions thereto, is charged to expense through DD&A over the life of the field.

Derivative Instruments and Hedging Activity

We are exposed to certain risks relating to our ongoing business operations, such as commodity price risk. Derivative contracts are utilized to economically hedge
our exposure to price fluctuations and reduce the variability in our cash flows associated with anticipated sales of future oil and natural gas production. We follow
FASB Accounting Standards Codification (“ASC”)

55

Topic 815, Derivatives and Hedging, to account for our derivative financial instruments. We do not enter into derivative contracts for speculative trading purposes.
It  is  our  policy  to  enter  into  derivative  contracts  only  with  counterparties  that  are  creditworthy  financial  institutions  deemed  by  management  as  competent  and
competitive. We did not post collateral under any of these contracts.

Our crude oil and natural gas derivative positions consist of swaps. Swaps are designed so that we receive or make payments based on a differential between fixed
and variable prices for crude oil and natural gas. We have elected to not designate any of our derivative contracts for hedge accounting. Accordingly, we record the
net change in the mark-to-market valuation of these derivative contracts, as well as all payments and receipts on settled derivative contracts, in “(Loss) gain on
derivative  contracts,  net”  on  the  Consolidated  Statements  of  Operations.  All  derivative  contracts  are  recorded  at  fair  market  value  and  are  included  in  the
Consolidated Balance Sheets as assets or liabilities.

Income Taxes and Uncertain Tax Positions

We  are  a  U.S.  company  operating  in  Texas,  as  of  December  31,  2020,  as  well  as  one  foreign  legal  entity,  Lynden  Corp,  which  is  a  Canadian  company.
Consequently, our tax provision is based upon the tax laws and rates in effect in the applicable jurisdiction in which our operations are conducted and income is
earned. The income tax rates imposed and methods of computing taxable income in these jurisdictions vary. Therefore, as a part of the process of preparing the
consolidated financial statements, we are required to estimate the income taxes in each of these jurisdictions. This process involves estimating the actual current tax
exposure  together  with  assessing  temporary  differences  resulting  from  differing  treatment  of  items,  such  as  depreciation,  amortization  and  certain  accrued
liabilities for tax and accounting purposes. Our effective tax rate for financial statement purposes will continue to fluctuate from year to year as our operations are
conducted in different taxing jurisdictions.

Our  corporate  structure  requires  the  filing  of  two  separate  consolidated  U.S.  Federal  income  tax  returns  and  one  Canadian  income  tax  return  resulting  from
Earthstone’s acquisition of Lynden Corp in 2016 (the “Lynden Arrangement”) that includes Lynden US, Earthstone, and Lynden Corp. As such, taxable income of
Earthstone cannot be offset by tax attributes, including net operating losses, of Lynden US, nor can taxable income of Lynden US be offset by tax attributes of
Earthstone. Earthstone and Lynden US record a tax provision, respectively, for their share of the book income or loss of EEH, net of the noncontrolling interest, as
well as any standalone income or loss generated by each company. As EEH is treated as a partnership for U.S. Federal income tax purposes, it is not subject to
income tax at the federal level and only recognizes the Texas Margin Tax.

On  January  7,  2021,  upon  closing  of  the  IRM  Acquisition,  the  acquired  entity,  Independence  Resources  Management,  LLC  (along  with  its  wholly  owned
subsidiaries,  collectively  “IRM”),  became  a  wholly  owned  subsidiary  of  EEH.  IRM’s  results  will  be  reported  on  the  U.S.  Return  of  Partnership  Income  (Form
1065) and will flow to EEH through Schedule K-1 (Form 1065). As IRM is treated as a Partnership, for federal and state income tax purposes, it is not subject to
income taxes at the federal level. At the state level, IRM only operates in Texas and is subject to the Texas Margin Tax.

Our deferred tax expense or benefit represents the change in the balance of deferred tax assets or liabilities reported in our Consolidated Balance Sheets. Valuation
allowances are established to reduce deferred tax assets when it is more likely than not that some portion or all of the deferred tax assets will not be realized. At
December 31, 2020 and 2019, we recorded a valuation allowance for our deferred tax assets in the Consolidated Balance Sheets.  

We apply the accounting standards related to uncertainty in income taxes. This accounting guidance clarifies the accounting for uncertainties in income taxes by
prescribing a minimum recognition threshold that a tax position is required to meet before being recognized in the consolidated financial statements. It requires that
we  recognize  in  the  consolidated  financial  statements  the  financial  effects  of  a  tax  position,  if  that  position  is  more  likely  than  not  of  being  sustained  upon
examination, including resolution of any appeals or litigation processes, based upon the technical merits of the position. It also provides guidance on measurement,
classification,  interest,  penalties  and  disclosure.  Our  tax  positions  related  to  our  pass-through  status  and  state  income  tax  liability,  including  deductibility  of
expenses, have been reviewed by our management and they believe those positions would more likely than not be sustained upon examination. Accordingly, we
have not recorded an income tax liability for uncertain tax positions at December 31, 2020 or 2019.

Revenue Recognition

We predominantly derive our revenue from the sale of produced oil, natural gas and natural gas liquids. Revenues are recognized when the recognition criteria of
FASB ASC Topic 606, Revenue from Contracts with Customers, are met, which generally occurs at the point in which title passes to the customers. We receive
payment from one to three months after delivery. At the end of each quarter, we estimate the amount of production delivered to purchasers and the price we will
receive. Variances between our estimated revenue and actual payment are recorded in the month the payment is received. Historically, however, differences have
been insignificant.

Accounting for Business Combinations

56

Our business has grown substantially through acquisitions, and our business strategy is to continue to pursue acquisitions as opportunities arise. We have accounted
for all of our business combinations to date using the purchase method.

Under the purchase method of accounting, a business combination is accounted for at a purchase price based upon the fair value of the consideration given. The
assets and liabilities acquired are measured at their fair value including the recognition of acquisition-related costs that are separate from the acquired net assets.
The purchase price is allocated to the assets and liabilities based upon these fair values. The excess of the cost of an acquired entity, if any, over the net amounts
assigned to assets acquired and liabilities assumed is recognized as goodwill. The excess of the fair value of assets acquired and liabilities assumed over the cost of
an acquired entity, if any, is allocated as a pro rata reduction of the amounts that otherwise would have been assigned to certain acquired assets.

Determining the fair values of the assets and liabilities acquired involves the use of judgment, since some of the assets and liabilities acquired do not have fair
values  that  are  readily  determinable.  Different  techniques  may  be  used  to  determine  fair  values,  including  market  prices  (where  available),  appraisals,  and
comparison to transactions for similar assets and liabilities, and present value of estimated future cash flows, among others. Since these estimates involve the use of
significant judgment, they can change as new information becomes available.

Goodwill

We account for goodwill in accordance with FASB ASC Topic 350, Intangibles – Goodwill and Other. Goodwill represents the excess of the purchase price over
the estimated fair value of the assets acquired net of the fair value of the liabilities assumed in an acquisition. ASC Topic 350 requires that goodwill be evaluated
on an annual basis for impairment or more frequently if an event occurs or circumstances change that could potentially result in an impairment.

We conduct a qualitative goodwill impairment assessment by examining relevant events and circumstances which could have a negative impact on our goodwill
such as, industry and market conditions, including commodity prices, costs factors, and other company specific events. If we conclude that it is not more likely
than not that the fair value of a reporting unit is less than its carrying value, then we do not have to perform the two-step impairment test. If after assessing the
totality of events or circumstances described, we determine that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the
two-step  goodwill  test  is  performed.  The  two-step  goodwill  impairment  test  is  also  performed  whenever  events  or  changes  in  circumstances  indicate  that  the
carrying value may not be recoverable. If, after performing the two-step goodwill test, it is determined that the carrying value of goodwill is impaired, the amount
of goodwill is reduced and a corresponding charge is made to earnings in the period in which the goodwill is determined to be impaired  

Noncontrolling Interest

We  account  for  noncontrolling  interest  in  accordance  with  FASB  ASC  Topic  810,  Consolidation,  which  requires  the  recording  of  a  noncontrolling  interest
component of Net (loss) income, as well as a noncontrolling interest component within equity. Noncontrolling interest represents third-party equity ownership of
EEH  and  is  presented  as  a  component  of  equity  in  the  Consolidated  Balance  Sheet  as  of  December  31,  2020  and  2019,  as  well  as  an  adjustment  to  Net  (loss)
income in the Consolidated Statement of Operations for the years ended December 31, 2020 and 2019.

As of December 31, 2020, Earthstone and Lynden US held 46.4% of the outstanding membership interests in EEH while Bold Holdings, the noncontrolling party,
held the remaining 53.6%. See further discussion in Note 9. Noncontrolling Interest in the Notes to Consolidated Financial Statements.

Internal Control Over Financial Reporting

Evaluation of Disclosure Controls and Procedures

(a) Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed by us in the reports that
we file or submit to the SEC under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified by the SEC’s rules and
forms, and that information is accumulated and communicated to our management, including our Chief Executive Officer and Principal Accounting Officer, as
appropriate to allow timely decisions regarding required disclosure.

In  accordance  with  Rules  13a-15(b)  and  15d-15(b)  under  the  Exchange  Act,  we  carried  out  an  evaluation,  under  the  supervision  and  with  the  participation  of
management, including our Chief Executive Officer and Principal Accounting Officer, of the effectiveness of our disclosure controls and procedures (as defined by
Rules  13a-15(e)  and  15d-15(e)  under  the  Exchange  Act)  as  of  the  end  of  the  period  covered  by  this  Annual  Report  on  Form  10-K.  As  described  below  under
paragraph (b) within Management’s Annual Report on Internal Control over Financial Reporting, our Chief Executive Officer and Principal Accounting Officer
have concluded that, as of the end of the period covered by this Annual Report on Form 10-K, our disclosure controls and procedures were effective to provide
reasonable assurance that information required to be disclosed by us in the reports that we file or submit to the SEC under the Exchange Act is recorded, processed,
summarized and reported within the time periods specified by the SEC’s rules and that such information is accumulated and communicated to our management,
including our Chief Executive Officer and Principal Accounting Officer, as appropriate to allow timely decisions regarding required disclosure.

The audit report of our independent registered public accounting firm, which is included in this Annual Report on Form 10-K, expressed an unqualified opinion on
our consolidated financial statements.

(b) Management’s Annual 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)
under the Exchange Act. Our internal control over financial reporting is 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. Our internal control over financial
reporting includes those policies and procedures that:

•

•

•

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect our transactions and dispositions of our assets;

provide  reasonable  assurance  that  transactions  are  recorded  as  necessary  to  permit  preparation  of  financial  statements  in  accordance  with
generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our
management; and

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could
have a material effect on the financial statements.

While “reasonable assurance” is a high level of assurance, it does not mean absolute assurance. Because of its inherent limitations, internal control over financial
reporting may not prevent or detect every misstatement and instance of fraud. Controls are susceptible to manipulation, especially in instances of fraud caused by
collusion of two or more people. 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.

Under the supervision and with the participation of our Chief Executive Officer and Principal Accounting Officer, our management conducted an evaluation of the
effectiveness  of  our  internal  control  over  financial  reporting  as  of  December  31,  2020.  In  making  this  evaluation,  management  used  the  Internal  Control  –
Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (“COSO”).  Based  on  the  results  of  our
evaluation, our management concluded that our internal control over financial reporting was effective, at the reasonable assurance level, as of December 31, 2020.

Our independent registered public accounting firm that audited our consolidated financial statements, has also issued its own audit report on the effectiveness of
our internal control over financial reporting as of December 31, 2020, which is included herein.

(c) Changes in Internal Control over Financial Reporting

58

There have not been any changes in our internal control over financial reporting during the quarter ended December 31, 2020 that have materially affected, or are
reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of
Earthstone Energy, Inc.

Opinion on Internal Control over Financial Reporting

We have audited Earthstone Energy, Inc. 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 (“COSO”). 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 COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the
consolidated balance sheets of Earthstone Energy, Inc. and subsidiaries as of December 31, 2020 and 2019, the related consolidated statements of
operations, equity and cash flows for the years then ended, and the related notes (collectively referred to as the “consolidated financial statements”)
and our report dated March 10, 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 Report on Internal Control over Financial
Reporting included in Item 9A. 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 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.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of
Earthstone Energy, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Earthstone Energy, Inc. and subsidiaries (the “Company”) as of December 31,
2020 and 2019, the related consolidated statements of operations, equity and cash flows for the years then ended, and the related notes
(collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material
respects, the consolidated financial position of the Company as of December 31, 2020 and 2019, and the consolidated results of its operations and
its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

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 March 10, 2021
expressed an unqualified opinion on the Company’s internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the
Company’s 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 to 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.

Assessment of the Estimated Proved Oil and Gas Reserves on the Determination of Depreciation, Depletion and Amortization Expense
related to Proved Oil and Natural Gas Properties and Impairment of Proved Oil and Natural Gas Properties

The Company’s net proved oil and natural gas properties balance was $731.7 million as of December 31, 2020, and the associated depreciation,
depletion and amortization (DD&A) expense and impairment expense for the year ended December 31, 2020 was $95.9 million and $25.3 million,
respectively. As described in Note 7 to the consolidated financial statements, the Company follows the successful efforts method of accounting for
its oil and natural gas properties. The Company’s lease acquisition costs and development costs of proved oil and natural gas properties are
amortized using the units-of-production method, at the field level, based on total estimated proved oil and natural gas reserves and estimated
proved developed oil and natural gas reserves, respectively. Proved oil and natural gas properties are reviewed for impairment on a nonrecurring
basis. The impairment charge reduces the carrying values to their estimated fair values. These fair value measurements are classified as Level 3
measurements and include many unobservable inputs. Fair value is calculated as the estimated discounted future

2

net cash flows attributable to the assets. The Company’s primary assumptions in preparing the estimated discounted future net cash flows to be
recovered from oil and natural gas properties are based on (i) proved reserves, (ii) forward commodity prices and assumptions as to costs and
expenses, and (iii) the estimated discount rate that would be used by potential purchasers to determine the fair value of the assets.

The principal considerations for our determination that performing procedures relating to the impact of proved oil and natural gas reserves on proved
net oil and natural gas properties is a critical audit matter are there was significant judgment by management, including the use of specialists, when
developing the estimates of proved oil and natural gas reserves. This in turn led to a high degree of auditor judgment, subjectivity, and effort in
performing procedures and evaluating the significant assumptions used in developing those estimates, including future production, future oil and
natural gas prices, future pricing differentials, and future development costs.

The primary procedures we performed to address this critical audit matter included:

•

•

•

•

•

Testing the operating effectiveness of controls relating to management’s estimates of proved oil and natural gas reserves, the calculation of
DD&A expense, and the impairment assessment of proved oil and natural gas properties.

Evaluating the significant assumptions used by management in developing these estimates, including future production, future oil and gas
prices, future pricing differentials, and future development costs.

Utilizing the work of management’s specialists to evaluate the reasonableness of the estimates of proved oil and natural gas reserves. As a
basis for this work, the specialists’ qualifications and objectivity were assessed, as well as the reasonableness of methods and assumptions
used by the specialists. The procedures performed also included testing the data used by the specialists and evaluating the specialists’
findings. Evaluating the significant assumptions relating to the estimates of proved oil and natural gas reserves also involved obtaining
evidence to support the reasonableness of the assumptions, including whether the assumptions used were reasonable considering the past
performance of the Company, and whether they were consistent with evidence obtained in other areas of the audit.

Testing management’s impairment assessment of proved oil and natural gas properties. This included evaluating management’s cash flow
analysis related to the proved oil and natural gas properties. In addition, we involved internal valuation professionals with specialized skills
and knowledge, who assisted in evaluating the discount rate used in the valuation by comparing it against a discount rate range that was
independently developed using publicly available market data for comparable entities.

Testing the inputs of and recalculating management’s DD&A calculation.

EARTHSTONE ENERGY, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. – Organization and Basis of Presentation

Earthstone Energy, Inc., a Delaware corporation (“Earthstone” and together with its consolidated subsidiaries, the “Company”), is a growth-oriented independent
oil  and  natural  gas  development  and  production  company.    In  addition,  the  Company  is  active  in  corporate  mergers  and  the  acquisition  of  oil  and  natural  gas
properties  that  have  production  and  future  development  opportunities.  The  Company’s  operations  are  all  in  the  up-stream  segment  of  the  oil  and  natural  gas
industry and all its properties are onshore in the United States.  

Earthstone is the sole managing member of Earthstone Energy Holdings, LLC, a Delaware limited liability company (together with its wholly-owned consolidated
subsidiaries, “EEH”), with a controlling interest in EEH. Earthstone, together with its wholly-owned subsidiary, Lynden Energy Corp., a corporation organized
under the laws of British Columbia (“Lynden Corp”), and Lynden Corp’s wholly-owned consolidated subsidiary, Lynden USA Inc., a Utah corporation (“Lynden
US”)  and  also  a  member  of  EEH,  consolidates  the  financial  results  of  EEH  and  records  a  noncontrolling  interest  in  the  Consolidated  Financial  Statements
representing the economic interests of EEH’s members other than Earthstone and Lynden US.

Note 2. – Summary of Significant Accounting Policies

Principles of Consolidation

The  Consolidated  Financial  Statements  include  the  accounts  and  balances  of  the  Company  and  have  been  prepared  in  accordance  with  accounting  principles
generally accepted in the United States (“GAAP”). All intercompany accounts and transactions, including revenues and expenses, are eliminated in consolidation.

Use of Estimates

The  preparation  of  the  Company’s  Consolidated  Financial  Statements  in  conformity  with  GAAP  requires  the  Company’s  management  to  make  estimates  and
assumptions  that  affect  the  reported  amounts  of  assets  and  liabilities  and  disclosure  of  contingent  assets  and  liabilities,  if  any,  at  the  date  of  the  Consolidated
Financial Statements and the reported amounts of revenues and expenses during the respective reporting periods then ended.

Estimated  quantities  of crude  oil, natural  gas and natural  gas liquids  reserves  are the most significant  of the  Company’s estimates.  All reserve  data  used in the
preparation  of  the  Consolidated  Financial  Statements,  as  well  as  included  in  Note  21.  Supplemental  Information  On  Oil  And  Gas  Exploration  And  Production
Activities (Unaudited), are based on estimates. Reservoir engineering is a subjective process of estimating underground accumulations of crude oil, natural gas and
natural  gas  liquids.  There  are  numerous  uncertainties  inherent  in  estimating  quantities  of  proved  crude  oil,  natural  gas  and  natural  gas  liquids  reserves.  The
accuracy of any reserve estimate is a function of the quality of available data and of engineering and geological interpretation and judgment. As a result, reserve
estimates may be different from the quantities of crude oil, natural gas and natural gas liquids that are ultimately recovered.

Other items subject to estimates and assumptions include, but are not limited to, the carrying amounts of property, plant and equipment, goodwill, asset retirement
obligations, valuation allowances for deferred income tax assets, valuation of derivative instruments and valuation of certain performance-based restricted stock
unit awards. Management evaluates estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic
and commodity price environment. The volatility of commodity prices results in increased uncertainty inherent in such estimates and assumptions. See Note 21.
Supplemental Information on Oil and Gas Exploration and Production Activities (Unaudited).

Although management believes these estimates are reasonable, actual results may differ from estimates and assumptions of future events and these revisions could
be  material.  Future  production  may  vary  materially  from  estimated  oil  and  natural  gas  proved  reserves.  Actual  future  prices  may  vary  significantly  from  price
assumptions used for determining proved reserves and for financial reporting.

Accounts Receivable

Accounts receivable include estimated amounts due from crude oil, natural gas, and natural gas liquids purchasers, other operators for which the Company holds an
interest, and from non-operating working interest owners. Accrued crude oil, natural gas, and natural gas liquids sales from purchasers and operators consist of
accrued  revenues  due  under  normal  trade  terms,  generally  requiring  payment  within  60  days  of  production.  For  receivables  from  joint  interest  owners,  the
Company typically has the ability to withhold future revenue disbursements to recover any non-payment of joint interest billings.

EARTHSTONE ENERGY, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

An  allowance  for  doubtful  accounts  is  established  based  on  reviews  of  individual  customer  accounts,  recent  loss  experience,  current  economic  conditions,  and
other pertinent factors. Accounts deemed uncollectible are charged to the allowance.

Provisions for bad debts and recoveries on accounts previously charged off are added to the allowance. The Company routinely assesses the recoverability of all
material  trade  receivables  and  other  receivables  to  determine  their  collectability.  Allowance  for  uncollectible  accounts  receivable  was  $0.02  million  and  $0.1
million at December 31, 2020 and 2019, respectively. 

Derivative Instruments

The Company utilizes derivative instruments in order to manage exposure to risks associated with fluctuating commodity prices and interest rates. The Company
recognizes  all  derivatives  as  either  assets  or  liabilities,  measured  at  fair  value,  and  recognizes  changes  in  the  fair  value  of  derivatives  in  current  earnings.  The
Company has elected to not designate any of its positions under the hedge accounting rules. Accordingly, these derivative contracts are mark-to-market and any
changes in the estimated values of derivative contracts held at the balance sheet date are recognized in Gain (loss) on derivative contracts, net in the Consolidated
Statements of Operations as unrealized gains or losses on derivative contracts.  Realized gains or losses on derivative contracts are also recognized in Gain (loss)
on derivative contracts, net in the Consolidated Statements of Operations.

Oil and Natural Gas Properties

The method of accounting for oil and natural gas properties determines what costs are capitalized and how these costs are ultimately matched with revenues and
expenses. The Company uses the successful efforts method of accounting for oil and natural gas properties. For more information see Note 7. Oil and Natural Gas
Properties.

Goodwill

Goodwill represents the excess of the purchase price of assets acquired over the fair value of those assets and is tested for impairment annually, or more frequently
if  events  or  changes  in  circumstances  indicate  that  the  carrying  value  of  goodwill  may  not  be  recoverable.  Such  test  includes  an  assessment  of  qualitative  and
quantitative factors.

A discounted future cash flow analysis of the properties to which the Goodwill was associated was performed based on commodity price futures as of March 31,
2020.  The  resulting  fair  value  was  lower  than  the  net  book  value  of  the  associated  properties.  Additionally,  the  Company’s  enterprise  value,  calculated  as  the
combined  market  capitalization  of  the  Company’s  equity  and  long-term  debt,  was  lower  than  the  book  value  of  its  assets,  without  allocating  between  the
Company's two major properties, Midland properties and Eagle Ford properties. Accordingly, the entire $17.6 million balance of Goodwill was impaired on that
date, resulting in no remaining amounts subject to impairment. There were no impairments to Goodwill recorded in the year ended December 31, 2019. For further
discussion, see Note 8. Goodwill.

Office and Other Equipment

Office  and  other  equipment  primarily  includes  leasehold  improvements,  vehicles,  computer  equipment  and  software,  office  furniture  and  fixtures  and  field
equipment. These items are recorded at cost, or fair value if acquired, and are depreciated using the straight-line method based on expected lives of the individual
assets or group of assets ranging from two years to 10 years. The Company had office and other equipment of $0.9 million and $1.3 million, net of accumulated
depreciation  and amortization  of  $3.7  million  and  $3.2 million,  at December  31, 2020 and 2019, respectively.  During  the years  ended  December  31, 2020 and
2019, the Company recognized depreciation expense of $0.5 million and $0.7 million, respectively. See separate finance lease disclosures in Note 19. Leases.

Noncontrolling Interest

Noncontrolling  Interest  represents  third-party  equity  ownership  of  EEH  and  is  presented  as  a  component  of  equity  in  the  Consolidated  Balance  Sheet  as  of
December 31, 2020 and 2019, as well as an adjustment to Net income in the Consolidated Statement of Operations for the years ended December 31, 2020 and
2019. As of December 31, 2020, Earthstone and Lynden US owned a 46.4% membership interest in EEH while Bold Energy Holdings, LLC (“Bold Holdings”),
the noncontrolling third-party, owned the remaining 53.6%. See further discussion in Note 9. Noncontrolling Interest.

Segment Reporting

Operating  segments  are  components  of  an  enterprise  that  (i)  engage  in  activities  from  which  it  may  earn  revenues  and  incur  expenses  (ii)  for  which  separate
operational financial information is available and is regularly evaluated by the chief operating decision maker for the purpose of allocating resources and assessing
performance.

Based on the Company’s organization and management, it has only one reportable operating segment, which is oil and natural gas exploration and production.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

Comprehensive Income

The Company has no elements of comprehensive income other than net income.

Asset Retirement Obligations

Asset retirement obligations associated with the retirement of long-lived assets are recognized as liabilities with an increase to the carrying amounts of the related
long-lived assets in the period incurred. The cost of the asset, including the asset retirement cost, is depreciated over the useful life of the asset. Asset retirement
obligations  are  recorded  at  estimated  fair  value,  measured  by  reference  to  the  expected  future  cash  outflows  required  to  satisfy  the  retirement  obligations
discounted  at  the  Company’s  credit-adjusted  risk-free  interest  rate.  Accretion  expense  is  recognized  over  time  as  the  discounted  liabilities  are  accreted  to  their
expected settlement value. If estimated future costs of asset retirement obligations change, an adjustment is recorded to both the asset retirement obligations and
the long-lived asset. Revisions to estimated asset retirement obligations can result from changes in retirement cost estimates, revisions to estimated inflation rates,
and changes in the estimated timing of abandonment. For further discussion, see Note 14. Asset Retirement Obligations.

Business Combinations

The Company accounts for its acquisitions of oil and gas properties not commonly controlled in accordance with Financial Accounting Standards Board (“FASB”)
Accounting Standards Codification (“ASC”) Topic 805, Business Combinations, which, among other things, requires the Company to determine if an asset or a
business has been acquired. If the Company determines an asset(s) has been acquired, the asset(s) acquired, as well as any liabilities assumed, are measured and
recorded  at  the  acquisition  date  cost.  If  the  Company  determines  a  business  has  been  acquired,  the  assets  acquired  and  liabilities  assumed  are  measured  and
recorded at their fair values as of the acquisition date, recording goodwill for amounts paid in excess of fair value.

Revenue Recognition

The Company’s revenues are comprised solely of revenues from customers and include the sale of oil, natural gas and natural gas liquids. The Company believes
that the disaggregation of revenue into these three major product types, as presented in the Consolidated Statements of Operations, appropriately depicts how the
nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors based on its single geographic region. Revenues are recognized
when  the  recognition  criteria  of  ASC  606  “Revenue  from  Contracts  with  Customers,”  (“ASC  606”)  are  met,  which  generally  occurs  at  a  point  in  time  when
production is sold to a purchaser at a determinable price, delivery has occurred, control has transferred and collection of the revenue is probable. The Company
fulfills its performance obligations under its customer contracts through delivery of oil, natural gas and natural gas liquids and revenues are recorded on a monthly
basis and the Company receives payment from one to three months after delivery. Generally, each unit of product represents a separate performance obligation.
The prices received for oil, natural gas and natural gas liquids sales under the Company’s contracts are generally derived from stated market prices which are then
adjusted to reflect deductions including transportation, fractionation and processing. As a result, revenues from the sale of oil, natural gas and natural gas liquids
will decrease if market prices decline. The sales of oil, natural gas and natural gas liquids, as presented on the Consolidated Statements of Operations, represent the
Company’s share of revenues net of royalties and excluding revenue interests owned by others. When selling oil, natural gas and natural gas liquids on behalf of
royalty or working interest owners, the Company is acting as an agent and thus reports the revenue on a net basis. To the extent actual volumes and prices of oil
and natural gas sales are unavailable for a given reporting period because of timing or information not received from third parties, the expected sales volumes and
prices  for those properties  are  estimated  and recorded.  Variances  between the Company’s estimated  revenue  and actual  payment are  recorded  in the month the
payment is received. Historically, however, differences have been insignificant.

At the end of each month when the performance obligation is satisfied, the variable consideration can be reasonably estimated and amounts due from customers are
recorded  in  “Accounts  receivable:  oil,  natural  gas,  and  natural  gas  liquids  revenues”  in  the  Consolidated  Balance  Sheets.  As  of  December  31, 2020 and 2019,
amounts receivable from contracts with customers were $16.3 million and $29.0 million, respectively. Taxes assessed by governmental authorities on oil, natural
gas and NGL sales are presented separately from such revenues in the Consolidated Statements of Operations.

Oil Sales

Oil production is transported from the wellhead to tank batteries or delivery points through flow-lines or gathering systems. Purchasers of the oil take delivery at (i)
the tank batteries and transport the oil by truck, or (ii) at a pipeline delivery point and the Company collects a market price, net of pricing differentials. Revenue is
recognized when control transfers to the purchaser at the net price received by the Company. Starting in October 2019, certain of the Company’s oil sales activity
involves buy/sell arrangements that effect a change in location with required repurchase of oil at a delivery point. Because the Company acts as

11

EARTHSTONE ENERGY, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

the agent in these transactions, the buy/sell activity is recorded on a net basis and the residual transportation fee is included in Lease operating expenses in the
Consolidated Statements of Operations.

Natural Gas and NGL Sales

Under the Company’s natural gas sales arrangements, the purchaser takes control of wet gas at a delivery point near the wellhead or at the inlet of the purchaser’s
processing facility. The purchaser gathers and processes the wet gas and remits proceeds to the Company for the resulting natural gas and NGL sales. Based on the
nature of these arrangements, the Company is the agent and the purchaser is the Company’s customer, thus, the Company recognizes natural gas and NGL sales
based on the net amount of proceeds received from the purchaser.

Imbalances

The Company recognizes revenue for all oil, natural gas and NGL sold to purchasers regardless of whether the sales are proportionate to the Company’s ownership
interest  in  the  property.  Production  imbalances  are  recognized  as  a  liability  to  the  extent  an  imbalance  on  a  specific  property  exceeds  the  Company’s  share  of
remaining proved oil, NGL and natural gas reserves. The Company is also subject to natural gas pipeline imbalances, which are recorded as accounts receivable or
payable at values consistent with contractual arrangements with the owner of the pipeline. The Company had no imbalances as of December 31, 2020 or 2019.

Contract Balances

Under  the  Company’s  product  sales  contracts,  the  Company  invoices  customers  once  performance  obligations  have  been  satisfied,  at  which  point  payment  is
unconditional. Accordingly, the Company’s product sales contracts do not give rise to contract assets or liabilities under ASC 606.

Transaction Price Allocated to Remaining Performance Obligations

Substantially all of the Company’s product sales are short-term in nature, with a contract term of one year or less. For these contracts, the Company has utilized the
practical  expedient  in  ASC  606  which  exempts  the  Company  from  the  requirements  to  disclose  the  transaction  price  allocated  to  remaining  performance
obligations if the performance obligation is part of a contract that has an original expected duration of one year or less.

For the Company’s product sales that have a contract term greater than one year, the Company has utilized the practical expedient in ASC 606 which states the
Company  is  not  required  to  disclose  the  transaction  price  allocated  to  remaining  performance  obligations  if  the  variable  consideration  is  allocated  entirely  to  a
wholly unsatisfied performance  obligation. Under these contracts, each unit of product generally represents a separate performance  obligation; therefore, future
volumes are wholly unsatisfied, and disclosure of the transaction price allocated to remaining performance obligations is not required.

Prior-Period Performance Obligations

The Company records revenue in the month that product is delivered to the purchaser. Settlement statements for certain natural gas and NGLs sales, however, may
not be received for 30 to 90 days after the date the product is delivered, and as a result the Company is required to estimate the amount of product delivered to the
purchaser and the price that will be received for the sale of the product. In these situations, the Company records the differences between its estimates and the
actual amounts received for product sales in the month that payment is received from the purchaser. Any identified differences between the Company’s revenue
estimates and actual revenue received have historically been insignificant. For the years ended December 31, 2020 and 2019, revenue recognized in the reporting
period related to performance obligations satisfied in prior reporting periods was not material.

Concentration of Credit Risk

Credit risk represents the actual or perceived financial loss that the Company would record if its purchasers, operators, or counterparties failed to perform pursuant
to contractual terms.

The  purchasers  of  the  Company’s  oil,  natural  gas,  and  natural  gas  liquids  production  consist  primarily  of  independent  marketers,  major  oil  and  natural  gas
companies and natural gas pipeline companies. Historically, the Company has not experienced any significant losses from uncollectible accounts. In the year ended
December 31, 2020, three purchasers accounted for 32%, 15% and 12%, respectively, of the Company’s oil, natural gas, and natural gas liquids revenues.  In the
year  ended  December  31,  2019,  three  purchasers  accounted  for  30%,  14%  and  12%,  respectively,  of  the  Company’s  oil,  natural  gas,  and  natural  gas  liquids
revenues. No other purchaser accounted for 10% or more of the Company’s oil, natural gas, and natural gas liquids revenues during the years ended December 31,
2020  and  2019.  Additionally,  at  December  31,  2020,  three  purchasers  accounted  for  18%,  17%  and  16%,  respectively,  of  the  Company’s  oil,  natural  gas  and
natural gas liquids receivables. At December 31, 2019, three purchasers accounted for 46%, 14% and 10%, respectively, of the Company’s oil,

12

EARTHSTONE ENERGY, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

natural  gas,  and  natural  gas  liquids  receivables.  No  other  purchaser  accounted  for  10%  or  more  of  the  Company’s  oil,  natural  gas,  and  natural  gas  liquids
receivables at December 31, 2020 or 2019.

The Company holds working interests in oil and natural gas properties for which a third-party serves as operator. The operator sells the oil, natural gas, and NGLs
to the purchaser, collects the cash, and distributes the cash to the Company. In the year ended December 31, 2020, one operator distributed 15% of the Company’s
oil, natural gas and natural gas liquids revenues. In the year ended December 31, 2019, no operator distributed 10% or more of the Company’s oil, natural gas and
natural gas liquids revenues.

The derivative instruments of the Company are with a small number of counterparties and, from time-to-time, may represent material assets in the Consolidated
Balance Sheets. At December 31, 2020, the Company had a net derivative asset position of $6.6 million. At December 31, 2019, the Company had $2.7 million of
derivative contracts that were in a material asset position.

The  Company  regularly  maintains  its  cash  in  bank  deposit  accounts.  Balances  held  by  the  Company  at  its  banks  typically  exceed  Federal  Deposit  Insurance
Corporation (“FDIC”) insurance  coverage  and, as a result, there is a concentration  of credit  risk related  to the amounts of deposit in excess of FDIC insurance
coverage.

Stock-Based Compensation

The Company recognized stock-based compensation expense associated with restricted stock units, which include both time- and performance-based awards. The
Company accounts for forfeitures of equity-based incentive awards as they occur. Stock-based compensation expense related to time-based restricted stock units is
based on the price of the Class A common stock, $0.001 par value per share of Earthstone (“Class A Common Stock”), on the grant date and recognized over the
vesting period using the straight-line method. Stock-based compensation expense related to performance-based restricted stock units, which cliff vest, is based on a
grant date Monte Carlo Simulation pricing model, which calculates multiple potential outcomes for an award and establishes fair value based on the most likely
outcome, and is recognized over the vesting period using the straight-line method. See Note 12. Stock-Based Compensation for further details.

Income Taxes

The Company is a U.S. company operating in Texas, as of December 31, 2020, as well as one foreign legal entity, Lynden Corp, which is a Canadian company.
Consequently, the Company’s tax provision is based upon the tax laws and rates in effect in the applicable jurisdiction in which its operations are conducted and
income  is  earned.  The  income  tax  rates  imposed  and  methods  of  computing  taxable  income  in  these  jurisdictions  vary.  Therefore,  as  a  part  of  the  process  of
preparing  the  Consolidated  Financial  Statements,  the  Company  is  required  to  estimate  the  income  taxes  in  each  of  these  jurisdictions.  This  process  involves
estimating  the  actual  current  tax  exposure  together  with  assessing  temporary  differences  resulting  from  differing  treatment  of  items,  such  as  depreciation,
amortization  and certain  accrued liabilities  for tax and accounting  purposes. The Company’s effective  tax rate for financial  statement purposes will continue to
fluctuate from year to year as its operations are conducted in different taxing jurisdictions.

The Company records an income tax provision consistent with its status as a corporation. The Company’s corporate structure requires the filing of two separate
consolidated  U.S.  Federal  income  tax  returns  and  one  Canadian  income  tax  return  resulting  from  Earthstone’s  acquisition  of  Lynden  Corp  in  May  2016  (the
“Lynden  Arrangement”)  that  includes  Lynden  US,  Earthstone,  and  Lynden  Corp.  As  such,  taxable  income  of  Earthstone  cannot  be  offset  by  tax  attributes,
including net operating losses, of Lynden US, nor can taxable income of Lynden US be offset by tax attributes of Earthstone. Earthstone and Lynden US record a
tax provision, respectively, for their share of the book income or loss of EEH, net of the noncontrolling interest, as well as any standalone income or loss generated
by each company. As EEH is treated as a partnership for U.S. Federal income tax purposes, it is not subject to income tax at the federal level and only recognizes
the Texas Margin Tax.

The  Company’s  deferred  tax  expense  or  benefit  represents  the  change  in  the  balance  of  deferred  tax  assets  or  liabilities  reported  in  the  Consolidated  Balance
Sheets. Valuation allowances are established to reduce deferred tax assets when it is more likely than not that some portion or all of the deferred tax assets will not
be realized. At December 31, 2020 and 2019, the Company has recorded a valuation allowance for its deferred tax assets in the Consolidated Balance Sheets.  

The Company applies the accounting standards related to uncertainty in income taxes. This accounting guidance clarifies the accounting for uncertainties in income
taxes by prescribing a minimum recognition threshold that a tax position is required to meet before being recognized in the Consolidated Financial Statements. It
requires that the Company recognize in the Consolidated Financial Statements the financial effects of a tax position, if that position is more likely than not of being
sustained upon examination, including resolution of any appeals or litigation processes, based upon the technical merits of the position. It also provides guidance
on  measurement,  classification,  interest,  penalties  and  disclosure.  The  Company’s  tax  positions  related  to  its  pass-through  status  and  state  income  tax  liability,
including deductibility of expenses, have been reviewed by the Company’s management and they believe those positions would more likely than not be sustained
upon

13

EARTHSTONE ENERGY, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

examination. Accordingly, the Company has not recorded an income tax liability for uncertain tax positions at December 31, 2020 or 2019.

Recently Issued Accounting Standards

Intangibles – Goodwill and Other – In January 2017, the FASB issued updated guidance simplifying the test for goodwill impairment. The update eliminates the
requirement to determine the implied value of goodwill in measuring an impairment loss. Upon adoption, the measurement of a goodwill impairment will represent
the excess of the reporting unit’s carrying value over its fair value and will be limited to the carrying value of goodwill. An entity still has the option to perform the
qualitative  assessment  for  a  reporting  unit  to  determine  if  the  quantitative  impairment  test  is  necessary.  The  update  is  effective  for  annual  and  interim  periods
beginning after December 15, 2019 and early adoption is permitted for interim or annual goodwill impairment tests performed after January 1, 2017. The Company
adopted the update effective January 1, 2020 and the impact was not material to the Consolidated Financial Statements. See further discussion of goodwill in Note
8. Goodwill.

Fair Value Measurements – In August 2018, the FASB issued an update which modifies the disclosure requirements on fair value measurements in Topic 820. The
ASU is effective for fiscal years beginning after December 15, 2019 and early adoption is permitted. The Company adopted the update effective January 1, 2020
and the impact was not material to the Consolidated Financial Statements.

Income Taxes -  In  December  2019,  the  FASB  issued  an  update  that  simplifies  the  accounting  for  income  taxes  by  removing  certain  exceptions  to  the  general
principles  in  Topic  740.  The  amendments  also  improve  consistent  application  of  and  simplify  GAAP for  other  areas  of  Topic  740  by  clarifying  and  amending
existing guidance. The amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020
and  early  adoption  is  permitted.  The  Company  adopted  the  update  effective  January  1,  2021  and  the  impact  was  not  material  to  the  Consolidated  Financial
Statements.

Credit Losses - In June 2016, the FASB issued an update that requires changes to the recognition of credit losses on financial instruments not accounted for at fair
value through net income, including loans, debt securities, trade receivables, net investments in leases and available-for-sale debt securities. The amended standard
broadens the information that an entity must consider in developing its estimate of expected credit losses, requiring an entity to estimate credit losses over the life
of  an  exposure  based  on  historical  information,  current  information  and  reasonable  and  supportable  forecasts.  The  guidance  is  effective  for  interim  and  annual
periods  beginning  after  December  15,  2019.  The  Company  adopted  the  update  effective  January  1,  2020  and  the  impact  was  not  material  to  the  Consolidated
Financial Statements.

Reference Rate Reform - In March 2020, the FASB issued an update that provides optional guidance for a limited period of time to ease the transition from LIBOR
to  an  alternative  reference  rate.  The  ASU  intends  to  address  certain  concerns  relating  to  accounting  for  contract  modifications  and  hedge  accounting.  These
optional  expedients  and  exceptions  to  applying  GAAP,  assuming  certain  criteria  are  met,  are  allowed  through  December  31,  2022.  The  Company  is  currently
evaluating the provisions of this update and has not yet determined whether it will elect the optional expedients. The Company does not expect the transition to an
alternative rate to have a material impact on its business, operations or liquidity.

Note 3. Acquisitions and Divestitures

The initial accounting for acquisitions and divestitures may not be complete and adjustments to provisional amounts, or recognition of additional assets acquired or
liabilities assumed, may occur as additional information is obtained about the facts and circumstances that existed as of the acquisition dates.

Midland Basin Acquisition

On January 7, 2021, the Company completed an acquisition as described in Note 20. Subsequent Event.

Divestitures

During  the  year  ended  December  31,  2019,  the  Company  sold  certain  non-core  properties  for  approximately  $4.2  million  in  cash,  resulting  in  a  gain  of
approximately  $3.6  million  recorded  in  Gain  on  sale  of  oil  and  gas  properties,  net  in  the  Consolidated  Statements  of  Operations.  There  were  no  material
divestitures during the year ended December 31, 2020.

Note 4. Transaction Costs

During the year ended December 31, 2020, the Company recorded transaction costs primarily due to legal, consulting and other fees of approximately $1.0 million
related to the acquisition noted above and $0.3 million related to other potential transactions, offset by net reimbursements of $0.7 million related to the business
combination (the “Bold Transaction”) pursuant to the Bold Contribution Agreement (as defined below) which closed on May 9, 2017.

EARTHSTONE ENERGY, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

During the year ended December 31, 2019, the Company recorded transaction costs totaling approximately $1.1 million primarily due to the Bold Transaction.

Note 5. Fair Value Measurements

FASB ASC Topic 820, defines fair value as 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.  ASC  Topic  820  provides  a  framework  for  measuring  fair  value,  establishes  a  three-level  hierarchy  for  fair  value
measurements  based  upon  the  transparency  of  inputs  to  the  valuation  of  an  asset  or  liability  as  of  the  measurement  date  and  requires  consideration  of  the
counterparty’s creditworthiness when valuing certain assets.

The three-level fair value hierarchy for disclosure of fair value measurements defined by ASC Topic 820 is as follows:

Level 1 – Unadjusted, quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. An active market is
defined as a market where transactions for the financial instrument occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2 – Inputs, other than quoted prices within Level 1, that are either directly or indirectly observable for the asset or liability through correlation with market
data at the measurement date and for the duration of the instrument’s anticipated life.

Level 3 – Prices or valuations that require unobservable inputs that are both significant to the fair value measurement and unobservable. Valuation under Level 3
generally involves a significant degree of judgment from management.

A financial  instrument’s level  within the fair  value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.  Where
available,  fair  value  is  based  on  observable  market  prices  or  parameters  or  derived  from  such  prices  or  parameters.  Where  observable  prices  or  inputs  are  not
available, valuation models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent
on the price transparency for the instruments or market and the instrument’s complexity. The Company reflects transfers between the three levels at the beginning
of the reporting period in which the availability of observable inputs no longer justifies classification in the original level. There were no transfers between fair
value hierarchy levels for the year ended December 31, 2020.

Fair Value on a Recurring Basis

Derivative financial instruments are carried at fair value and measured on a recurring basis. The derivative financial instruments consist of swaps for crude oil and
natural gas and interest rate swaps. The Company’s commodity price hedges and interest rate swaps are valued based on discounted future cash flow models that
are primarily based on published forward commodity price curves and published LIBOR forward curves; thus, these inputs are designated as Level 2 within the
valuation hierarchy.

The fair values of derivative instruments in asset positions include measures of counterparty nonperformance risk, and the fair values of derivative instruments in
liability positions include measures of the Company’s nonperformance risk. These measurements were not material to the Consolidated Financial Statements.

Other financial instruments include cash, accounts receivable and payable, and revenue royalties. The carrying amount of these instruments approximates fair value
because of their short-term nature. The Company’s long-term debt obligation bears interest at floating market rates, therefore carrying amounts and fair value are
approximately equal.

Fair Value on a Nonrecurring Basis

The Company applies the provisions of the fair value measurement standard on a non-recurring basis to its non-financial assets and liabilities, including oil and gas
properties and goodwill. These assets and liabilities are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain
circumstances. 

Proved Oil and Natural Gas Properties

Proved oil and natural gas properties are reviewed for impairment on a nonrecurring basis. The impairment charge reduces the carrying values to their estimated
fair values. These fair value measurements are classified as Level 3 measurements and include many unobservable inputs. Fair value is calculated as the estimated
discounted future net cash flows attributable to the assets. The Company’s primary assumptions in preparing the estimated discounted future net cash flows to be
recovered from oil and natural gas properties are based on (i) proved reserves, (ii) forward commodity prices and assumptions as to costs and expenses, and (iii) the
estimated discount rate that would be used by potential purchasers to determine the fair value of the assets. See Note 7. Oil and Natural Gas Properties. 

Performance Units

Among  other  things,  the  Earthstone  Amended  and  Restated  2014  Long-Term  Incentive  Plan  (the  “2014  Plan”)  allows  for  the  grant  of  performance  units.  The
Company  accounts  for  these  awards  as  market-based  awards  which  are  valued  utilizing  the  Monte  Carlo  Simulation  pricing  model,  which  calculates  multiple
potential outcomes for an award and establishes grant date fair value based on the most likely outcome. See Note 12. Stock-Based Compensation. 

Goodwill

Goodwill represents the excess of the purchase price of assets acquired over the fair value of those assets and is tested for impairment annually, or more frequently
if events or changes in circumstances dictate that the fair value of goodwill may be less than its carrying amount. Such test includes an assessment of qualitative
and quantitative factors. See Note 8. Goodwill.

EARTHSTONE ENERGY, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

The Company records the identifiable assets acquired and liabilities  assumed at fair value at the date of acquisition on a nonrecurring basis. Fair value may be
estimated using comparable market data, a discounted cash flow method, or a combination of the two. In the discounted cash flow method, estimated future cash
flows are based on management’s expectations for the future and include estimates of future oil and natural gas production, commodity prices based on NYMEX
commodity futures price strips as of the date of the estimate, operating and development costs, and a risk-adjusted discount rate. The future oil and natural gas
pricing  used  in  the  valuation  is  a  Level  2  assumption.  Significant  Level  3  assumptions  associated  with  the  calculation  of  discounted  cash  flows  used  in  the
determination  of  fair  value  of  the  acquisition  include  the  Company’s  estimate  operating  and  development  costs,  anticipated  production  of  proved  reserves,
appropriate risk-adjusted discount rates and other relevant data. The Company’s acquisitions are discussed in Note 3. Acquisitions and Divestitures.

Asset Retirement Obligations

The asset retirement obligation estimates are derived from historical costs and management’s expectation of future cost environments; and therefore, the Company
has designated these liabilities as Level 3. The significant inputs to this fair value measurement include estimates of plugging, abandonment and remediation costs,
well life, inflation and credit-adjusted risk-free rate. See Note 14. Asset Retirement Obligations for a reconciliation of the beginning and ending balances of the
liability for the Company’s asset retirement obligations.

Note 6. Derivative Financial Instruments

Commodity Derivative Instruments

The Company’s hedging activities consist of derivative instruments entered into in order to hedge against changes in oil and natural gas prices through the use of
fixed  price  swaps  and  basis  swaps  agreements.  Swaps  exchange  floating  price  risk  in  the  future  for  a  fixed  price  at  the  time  of  the  hedge.  Consistent  with  its
hedging policy, the Company has entered into a series of derivative instruments to hedge a significant portion of its expected oil and natural gas production through
December  31,  2021.  Typically,  these  derivative  instruments  require  payments  to  (receipts  from)  counterparties  based  on  specific  indices  as  required  by  the
derivative agreements. Although not risk free, the Company believes these instruments reduce its exposure to oil and natural gas price fluctuations and, thereby,
allow the Company to achieve a more predictable cash flow.

The Company’s derivative instruments are cash flow hedge transactions in which it is hedging the variability of cash flow related to a forecasted transaction. The
Company  does  not  enter  into  derivative  instruments  for  trading  or  other  speculative  purposes.  These  transactions  are  recorded  in  the  Consolidated  Financial
Statements in accordance with FASB ASC Topic 815. The Company has accounted for these transactions using the mark-to-market accounting method. Generally,
the Company incurs accounting losses on derivatives during periods where prices are rising and gains during periods where prices are falling which may cause
significant fluctuations in the Consolidated Balance Sheets and Consolidated Statements of Operations.

The  Company nets  its derivative  instrument  fair  value  amounts  executed  with  each  counterparty  pursuant  to  an  International  Swap Dealers  Association  Master
Agreement (“ISDA”), which provides for net settlement over the term of the contract. The ISDA is a standard contract that governs all derivative contracts entered
into  between  the  Company  and  the  respective  counterparty.  The  ISDA  allows  for  offsetting  of  amounts  payable  or  receivable  between  the  Company  and  the
counterparty, at the election of both parties, for transactions that occur on the same date and in the same currency.

Note 7. Oil and Natural Gas Properties

The Company follows the successful efforts method of accounting for its oil and natural gas properties. Under this method, costs to acquire oil and natural gas
properties,  drill  and  equip  exploratory  wells  that  find  proved  reserves,  and  drill  and  equip  development  wells  are  capitalized.  Exploration  costs,  including
unsuccessful  exploratory  wells  and  geological  and  geophysical  costs,  are  charged  to  operations  as  incurred.  Upon  sale  or  retirement  of  oil  and  natural  gas
properties, the costs and related accumulated depreciation, depletion and amortization are eliminated from the accounts and the resulting gain or loss is recognized.

Costs incurred to maintain wells and related equipment, lease and well operating costs, and other exploration costs are charged to expense as incurred. Gains and
losses arising from the sale of properties are included in operating income in the Consolidated Statements of Operations.

The Company’s lease acquisition costs and development costs of proved oil and natural gas properties are amortized using the units-of-production method, at the
field level, based on total proved reserves and proved developed reserves, respectively. Depletion expense for oil and natural gas producing property and related
equipment was $95.9 million and $68.5 million for the years ended December 31, 2020 and 2019, respectively.

Proved Oil and Natural Gas Properties

Proved oil and natural gas properties are reviewed for impairment on a nonrecurring basis. The impairment charge reduces the carrying values to their estimated
fair values. These fair value measurements are classified as Level 3 measurements and include many unobservable inputs. Fair value is calculated as the estimated
discounted future net cash flows attributable to the assets. The Company’s primary assumptions in preparing the estimated discounted future net cash flows to be
recovered from oil and natural gas properties are based on (i) proved reserves, (ii) forward commodity prices and assumptions as to costs and

18

 
 
 
EARTHSTONE ENERGY, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

expenses, and (iii) the estimated discount rate that would be used by potential purchasers to determine the fair value of the assets.

Unproved Oil and Natural Gas Properties

Unproved  properties  consist  of  costs  incurred  to  acquire  undeveloped  leases  as  well  as  the  cost  to  acquire  unproved  reserves.  Undeveloped  lease  costs  and
unproved reserve acquisition costs are capitalized. Unproved oil and natural gas leases are generally for a primary term of three to five years. In most cases, the
term of the unproved leases can be extended by paying delay rentals, meeting contractual drilling obligations, or by the presence of producing wells on the leases.
Unproved costs related to successful exploratory drilling are reclassified to proved properties and depleted on a units-of-production basis.

The  Company  reviews  its  unproved  properties  periodically  for  impairment.  In  determining  whether  an  unproved  property  is  impaired,  the  Company  considers
numerous  factors  including,  but  not  limited  to,  current  exploration  and  development  plans,  favorable  or  unfavorable  exploration  activity  on  the  property  being
evaluated and/or adjacent properties, the Company’s geologists’ evaluation of the property, and the remaining months in the lease term for the property.

Impairments to Oil and Natural Gas Properties

During the year ended December 31, 2020, primarily as a result of the decline in crude oil price futures, the Company recorded non-cash impairment charges of
$25.3 million to its proved oil and natural gas properties and $13.2 million to its unproved oil and natural gas properties, located in the Eagle Ford Trend. As a
result of certain acreage expirations, the Company recorded non-cash impairment charges of $8.4 million to its unproved oil and natural gas properties during the
year ended December 31, 2020.

The Company recorded no non-cash asset impairment charges for the year ended December 31, 2019.

Accumulated  impairments  to  proved  and  unproved  oil  and  natural  gas  properties  as  of  December  31,  2020  and  2019  were  $168.0  million  and  $121.1  million,
respectively.

Note 8. Goodwill

Goodwill represents the excess of the purchase price of assets acquired over the fair value of those assets. The fair value of Goodwill is classified as a Level 3
measurement according to the fair value hierarchy defined by ASC 820. Goodwill is tested for impairment annually, or more frequently if events or changes in
circumstances dictate that the carrying value of goodwill may not be recoverable. Such test includes an assessment of qualitative and quantitative factors. If the
results of such tests are such that the fair value of the reporting unit is less than the carrying value, goodwill is then reduced by an amount that is equal to the
amount by which the carrying value exceeds the fair value.

A discounted future cash flow analysis of the properties to which the Goodwill was associated was performed based on commodity price futures as of March 31,
2020.  The  resulting  fair  value  was  lower  than  the  net  book  value  of  the  associated  properties.  Additionally,  the  Company’s  enterprise  value,  calculated  as  the
combined  market  capitalization  of  the  Company’s  equity  and  long-term  debt,  was  lower  than  the  book  value  of  its  assets,  without  allocating  between  the
Company's two major properties, Midland properties and Eagle Ford properties. Accordingly, the entire $17.6 million balance of Goodwill was impaired on that
date, resulting in no remaining amounts subject to impairment. The goodwill impairment charge is included in Impairment expense in the Consolidated Statement
of Operations for the year ended December 31, 2020. The Company did not have any non-cash impairment charges to Goodwill for the year ended December 31,
2019.

Accumulated impairments to Goodwill as of December 31, 2020 and 2019 were $36.7 million and $19.1 million, respectively.

Note 9. Noncontrolling Interest

Earthstone consolidates the financial results of EEH and its subsidiaries, and records a noncontrolling interest for the economic interest in Earthstone held by the
members of EEH other than Earthstone and Lynden US. Net income attributable to noncontrolling interest in the Consolidated Statements of Operations for the
year ended December 31, 2020 represents the portion of net income attributable to the economic interest in the Company held by the members of EEH other than
Earthstone  and  Lynden  US.  Noncontrolling  interest  in  the  Consolidated  Balance  Sheet  as  of  December  31,  2020  represents  the  portion  of  net  assets  of  the
Company attributable to the members of EEH other than Earthstone and Lynden US.

Class A Common Stock

At December 31, 2020 and 2019, there were 30,343,421 and 29,421,131 shares of Class A Common Stock issued and outstanding, respectively. During the years
ended December 31, 2020 and 2019, as a result of the vesting and settlement of restricted stock units under the 2014 Plan, Earthstone issued 914,905 and 736,706
shares of Class A Common Stock, respectively, of which 243,924 and 203,394 shares of Class A Common Stock, respectively, were retained as treasury stock and
canceled to satisfy the related employee income tax liability.

Class B Common Stock

At December  31, 2020 and  2019, there  were  35,009,371  and 35,260,680 shares  of  Class B Common  Stock  issued and  outstanding,  respectively.  Each share  of
Class B Common Stock, together with one EEH Unit, is convertible into one share of Class A Common Stock. During the years ended December 31, 2020 and
2019, 251,309 and 191,498 shares, respectively, of Class B Common Stock and EEH Units were exchanged for an equal number of shares of Class A Common
Stock.

Note 12. Stock-Based Compensation

Restricted Stock Units

The 2014 Plan allows, among other things, for the grant of restricted stock units (“RSUs”). As of December 31, 2020, the maximum number of shares of Class A
Common Stock that may be issued under the 2014 Plan was 9.4 million shares.

Each  RSU  represents  the  contingent  right  to  receive  one  share  of  Class  A  Common  Stock.  The  holders  of  outstanding  RSUs  do  not  receive  dividends  or  have
voting rights prior to vesting and settlement. The Company determines the fair value of granted RSUs based on the market price of the Class A Common Stock on
the date of the grant. Compensation expense for granted RSUs is recognized on a straight-line basis over the vesting term and is net of forfeitures, as incurred.
Stock-based compensation is included in General and administrative expense in the Consolidated Statements of Operations and is recorded with a corresponding
increase in Additional paid-in capital within the Consolidated Balance Sheets.

and $6.5 million, respectively, with a weighted average grant date fair value per share of $5.07 and $6.04, respectively. The total vesting date fair value of the
RSUs that vested during 2020 and 2019 was $3.0 million and $4.2 million, respectively. As of December 31, 2020, there was approximately $5.7 million of total
unrecognized  stock-based  compensation  expense  related  to unvested RSUs, which will be amortized  over the remaining  vesting  periods. The weighted average
remaining vesting period of the unrecognized compensation expense is 0.98 years.

For the years ended December 31, 2020 and 2019, stock-based compensation related to RSUs was $5.4 million and $5.9 million, respectively.

On January 30, 2020, the Board of Directors of Earthstone (the “Board”) granted 1,043,800 PSUs (the “2020 PSUs”) to certain officers pursuant to the 2014 Plan
(the “2020 Grant”). The 2020 Grant was subject to the approval of an amendment to the 2014 Plan to increase the number of available shares available thereunder
(the “2014 Plan Amendment”). The 2014 Plan Amendment was approved at the 2020 annual meeting of stockholders held on June 3, 2020. The 2020 PSUs are
payable in shares of Class A Common Stock based upon the achievement by the Company over a period commencing on February 1, 2020 and ending on January
31, 2023 (the “Performance Period”) of certain performance criteria established by the Board.

The 2020 PSUs are eligible to be earned based on the annualized  Total Shareholder  Return (“TSR”) of the Class A Common Stock during a three-year  period
beginning on February 1, 2020. Between 0x to 2.0x of the Performance Units are eligible to be earned based on Earthstone achieving an annualized TSR based on
the following pre-established goals:

Earthstone’s Annualized TSR
23.9% or greater
14.5%
8.4%
Less than 8.4%

TSR Multiplier
2.0
1.0
0.5

In the event that greater than 1.0x of the 2020 PSUs are earned, such additional PSUs may be paid in cash rather than the issuance of shares of Class A Common
Stock. Based on the COVID-19 pandemic and the recent commodity price crash, the Company believes that the target annualized TSR of 14.5% included in the
2020 PSU awards will be difficult to achieve.

The Company accounts for these awards as market-based awards which are valued utilizing the Monte Carlo Simulation pricing model, which calculates multiple
potential outcomes for an award and establishes grant date fair value based on the most likely outcome. For the 2020 PSUs, assuming a risk-free rate of 1.4% and
volatility of 62.0%, the Company calculated the weighted average grant date fair value per PSU to be $5.36.

As  of  December  31,  2020,  there  was  $6.1  million  of  unrecognized  compensation  expense  related  to  the  PSU  awards  which  will  be  amortized  over  a  weighted
average period of 0.88 years.

For the years ended December 31, 2020 and 2019, stock-based compensation related to the PSUs was approximately $4.6 million and $2.7 million, respectively.

Note 13. Long-Term Debt

Credit Agreement

On November 21, 2019, Earthstone, EEH (the “Borrower”), Wells Fargo Bank, National Association, as Administrative Agent and Issuing Bank (“Wells Fargo”),
Royal Bank of Canada, as Syndication Agent, BOKF, NA dba Bank of Texas (“BOKF”) as Issuing Bank with respect to Existing Letters of Credit, Truist Bank, as
successor  by  merger  to  SunTrust  Bank,  as  Documentation  Agent,  and  the  lenders  party  thereto  (the  “Lenders”)  entered  into  a  credit  agreement  (the  “Credit
Agreement”), which replaced the Prior Credit Agreement (as defined below), which was terminated on November 21, 2019.

Concurrently with the effectiveness of the Credit Agreement, the Company terminated that certain credit agreement, dated as of May 9, 2017 (the “Prior Credit
Agreement”), by and among the Borrower, Earthstone Operating, LLC, EF Non-Op, LLC, Sabine River Energy, LLC, Earthstone Legacy Properties, LLC, Lynden
USA Operating, LLC, Bold Energy III LLC (“Bold”), Bold Operating, LLC, the guarantors party thereto, the lenders party thereto, and BOKF, as administrative
agent.

On  March  27,  2020,  in  connection  with  a  redetermination  of  the  borrowing  base  under  the  Credit  Agreement,  the  borrowing  base  was  set  at  $275  million,
representing a 15% decrease from the previous borrowing base of $325 million.

On September 28, 2020, Earthstone, EEH, Wells Fargo, the guarantors party thereto, and the Lenders entered into an amendment (the “Amendment”) to the Credit
Agreement.  Among  other  things,  the  Amendment  decreased  the  borrowing  base  from  $275  million  to  $240  million,  increased  the  interest  rate  on  outstanding
borrowings by 25 to 50 basis points, increased the flexibility to finance and make acquisitions, and added certain restrictions related to dividends and distributions.

The  next  regularly  scheduled  redetermination  of  the  borrowing  base  is  on  or  around  April  1,  2021.  Subsequent  redeterminations  will  occur  on  or  about  each
November  1st  and  May  1st  thereafter.  The  amounts  borrowed  under  the  Credit  Agreement  bear  annual  interest  rates  at  either  (a)  the  adjusted  LIBO  Rate  (as
customarily defined) (the “Adjusted LIBO Rate”) plus 2.00% to 3.25% or (b) the sum of (i) the greatest of (A) the prime rate of Wells Fargo, (B) the federal funds
rate  plus  ½  of  1.0%,  and  (C)  the  Adjusted  LIBO  Rate  for  an  interest  rate  period  of  one  month  plus  1.0%,  (ii)  plus  1.00%  to  2.25%,  depending  on  the  amount
borrowed under the Credit Agreement. Principal amounts outstanding under the Credit Agreement are due and payable in full at maturity on November 21, 2024.
All of the obligations under the Credit Agreement, and the guarantees of those obligations, are secured by substantially all of EEH’s assets. Additional payments
due under the Credit Agreement include paying a commitment fee of 0.375% to 0.50% per year, depending on the amount borrowed under the Credit Agreement,
to the Lenders in respect of the unutilized commitments thereunder. EEH is also required to pay customary letter of credit fees.

Effective May 2020, the Company entered into certain interest rate swaps, exchanging the LIBO Rate for a fixed rate of 0.286% (the “Swap”). The initial notional
amount of the Swap is $125 million through May 2022 and decreases to $100 million through May 2023 and $75 million through May 2024.

The  Credit  Agreement  contains  a  number  of  covenants  that,  among  other  things,  restrict,  subject  to  certain  exceptions,  EEH’s  ability  to  incur  additional
indebtedness,  create  liens  on  assets,  make  investments,  pay  dividends  and  distributions  or  repurchase  its  limited  liability  interests,  engage  in  mergers  or
consolidations, sell certain assets, sell or discount any notes receivable or accounts receivable and engage in certain transactions with affiliates.

In addition, the Credit Agreement requires EEH to maintain the following financial covenants: a current ratio of not less than 1.0 to 1.0 and a consolidated leverage
ratio of not greater than 3.5 to 1.0. Consolidated leverage ratio means the ratio of (i) the aggregate debt of EEH and its consolidated subsidiaries as at the last day
of the fiscal quarter to (ii) EBITDAX for the applicable period, which was calculated as EBITDAX for the four consecutive fiscal quarters ending on such date.
The term “EBITDAX” means, for any period, the sum of consolidated net income for such period plus (a) the following expenses or charges to the extent deducted
from consolidated net income in such period: (i) interest, (ii) taxes, (iii) depreciation, (iv)

depletion, (v) amortization, (vi) certain distributions to employees related to the stock compensation, (vii) certain transaction related expenses, (viii) reimbursed
indemnification expenses related to certain dispositions and investments, (ix) non-cash extraordinary, usual, or nonrecurring expenses or losses, (x) other non-cash
charges  and  minus  (b)  to  the  extent  included  in  consolidated  net  income  in  such  period:  (i)  non-cash  income,  (ii)  gains  on  asset  dispositions,  disposals  and
abandonments outside of the ordinary course of business and (iii) to the extent not otherwise deducted from consolidated net income, the aggregate amount of any
pass-through cash distributions received by Borrower during such period in an amount equal to the aggregate amount of pass-through cash distributions actually
made by Borrower during such period.

The Credit Agreement contains customary affirmative covenants and defines events of default to include failure to pay principal or interest, breach of covenants,
breach of representations and warranties, insolvency, judgment default and a change in control. Upon the occurrence and continuance of an event of default, the
Lenders have the right to accelerate repayment of the loans and exercise their remedies with respect to the collateral. At December 31, 2020, the Company was in
compliance with all covenants under the Credit Agreement.

As  of  December  31,  2020,  the  Company  had  a  $240.0  million  borrowing  base  under  the  Credit  Agreement,  of  which  $115.0  million  was  outstanding,  bearing
annual interest of 2.400%, resulting in an additional $125.0 million of borrowing base availability under the Credit Agreement. At December 31, 2019, there were
$170.0 million of borrowings outstanding under the Credit Agreement.

For the year ended December 31, 2020, the Company had borrowings of $136.1 million and $191.1 million in repayments of borrowings.

For  the  years  ended  December  31,  2020  and  2019,  interest  on  all  outstanding  debt  averaged  2.83%  and  4.42%  per  annum,  respectively,  which  excluded
commitment fees of $0.6 million and $0.7 million for each period ended, respectively, and amortization of deferred financing costs of $0.3 million and $0.4 million
for each period ended, respectively.  

No  costs  associated  with  the  Credit  Agreement  were  capitalized  during  the  year  ended  December  31,  2020.  The  Company  capitalized  $1.6  million  of  costs
associated with the Credit Agreement for the year ended December 31, 2019. These capitalized costs are included in Other noncurrent assets in the Consolidated
Balance Sheets. The Company’s policy is to capitalize the financing costs associated with its debt and amortize those costs on a straight-line basis over the term of
the associated debt, which approximates the effective interest method over the term of the related debt.

Amendment to the Credit Agreement

On December 17, 2020, Earthstone, EEH, as Borrower, Wells Fargo Bank, National Association (“Wells Fargo”), as Administrative Agent, the guarantors party
thereto, and the lenders party thereto (the “Lenders”) entered into an amendment (the “Amendment”) to the Credit Agreement. The Amendment was effective upon
the closing of the acquisition described in Note 20. Subsequent Event. Among other things, the Amendment (i) joined certain financial institutions as additional
lenders, increased the borrowing base from $240.0 million to $360.0 million, (ii) increased the interest rate on outstanding borrowings; and (iii) adjusted some of
the financial covenants.  

Note 14. Asset Retirement Obligations

The  Company  has  asset  retirement  obligations  associated  with  the  future  plugging  and  abandonment  of  oil  and  natural  gas  properties  and  related  facilities.
Revisions to the liability typically occur due to changes in the estimated abandonment costs, well economic lives, and the discount rate.

The  following  table  summarizes  the  Company’s  asset  retirement  obligation  transactions  recorded  during  the  years  ended  December  31,  2020  and  2019  (in

making shall be disclosed so that users of the financial statements can evaluate their significance.

Earthstone's  significant  shareholder  consists  of various  investment  funds managed  by a  private  equity  firm  who may manage  other  investments  in entities  with
which the Company interacts in the normal course of business. On February 12, 2020, the Company sold certain of its interests in oil and natural gas leases and
wells  in  an  arm’s  length  transaction  to  a  portfolio  company  of  Earthstone’s  significant  shareholder  (not  under  common  control)  for  cash  consideration  of
approximately $0.4 million.

In connection with the Olenik v. Lodzinski et al. lawsuit described below in Note 16. Commitments and Contingencies, Earthstone’s significant shareholder was
also named in the lawsuit. As a result of the Settlement Agreement (defined below), the Company has concluded negotiations with its insurance carrier regarding
an allocation of defense costs and settlement contributions above its deductible for all the parties named in the lawsuit.

The Company has a non-cancelable fixed cost agreement of $1.6 million per year through May 2021 to reserve pipeline capacity of 10,000 MMBtu per day for
gathering  and  processing  related  to  certain  Eagle  Ford  assets  in  south  Texas.  As  the  operator  of  the  properties  dedicated  to  this  contract,  the  gross  amount  of
obligation is provided; however, the Company’s net share is approximately 31%.

Additionally, the Company leases corporate office space in The Woodlands, Texas and Midland, Texas. Rent expense was approximately $0.8 million and $0.8
million,  for  the  years  ended  December  31,  2020  and  2019,  respectively.    Minimum  lease  payments  under  the  terms  of  non-cancelable  operating  leases  as  of
December 31, 2020 are shown in the table above.

Environmental

The  Company’s  operations  are  subject  to  risks  normally  associated  with  the  drilling,  completion  and  production  of  oil  and  gas,  including  blowouts,  fires,  and
environmental risks such as oil spills or gas leaks that could expose the Company to liabilities associated with these risks.

In the Company’s acquisition of existing or previously drilled well bores, the Company may not be aware of prior environmental safeguards, if any, that were taken
at  the  time  such  wells  were  drilled  or  during  such  time  the  wells  were  operated.  The  Company  maintains  comprehensive  insurance  coverage  that  it  believes  is
adequate to mitigate the risk of any adverse financial effects associated with these risks.

However, should it be determined that a liability exists with respect to any environmental cleanup or restoration, the liability to cure such a violation could still fall
upon the Company. No claim has been made, nor is the Company aware of any liability which the Company may have, as it relates to any environmental cleanup,
restoration, or the violation of any rules or regulations relating thereto except for the matter discussed above.

Legal

From time to time, Earthstone and its subsidiaries may be involved in various legal proceedings and claims in the ordinary course of business.

Olenik v. Lodzinski et al.: On June 2, 2017, Nicholas Olenik filed a purported shareholder class and derivative action in the Delaware Court of Chancery against
Earthstone’s  Chief  Executive  Officer,  along  with  other  members  of  the  Board,  EnCap  Investments  L.P.  (“EnCap”),  Bold,  Bold  Holdings  and  Oak  Valley
Resources,  LLC.  The  complaint  alleges  that  Earthstone’s  directors  breached  their  fiduciary  duties  in  connection  with  the  contribution  agreement  dated  as  of
November  7,  2016  and  as  amended  on  March  21,  2017  (the  “Bold  Contribution  Agreement”),  by  and  among  Earthstone,  EEH,  Lynden  US,  Lynden  USA
Operating, LLC, Bold Holdings and Bold. The Plaintiff asserts that the directors negotiated the business combination pursuant

24

 
EARTHSTONE ENERGY, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

to  the  Bold  Contribution  Agreement  (the  “Bold  Transaction”)  to  benefit  EnCap  and  its  affiliates,  failed  to  obtain  adequate  consideration  for  the  Earthstone
shareholders who were not affiliated with EnCap or Earthstone management, did not follow an adequate process in negotiating and approving the Bold Transaction
and  made  materially  misleading  or  incomplete  proxy  disclosures  in  connection  with  the  Bold  Transaction.  The  suit  seeks  unspecified  damages  and  purports  to
assert  claims  derivatively  on  behalf  of  Earthstone  and  as  a  class  action  on  behalf  of  all  persons  who  held  common  stock  up  to  March  13,  2017,  excluding
defendants and their affiliates. On July 20, 2018, the Delaware Court of Chancery granted the defendants’ motion to dismiss and entered an order dismissing the
action in its entirety with prejudice. The Plaintiff filed an appeal with the Delaware Supreme Court. On April 5, 2019, the Delaware Supreme Court affirmed the
Delaware Court of Chancery’s dismissal of the proxy disclosure claims but reversed the Delaware Court of Chancery’s dismissal of the other claims, holding that
the  allegations  with  respect  to  those  claims  were  sufficient  for  pleading  purposes.  After  engaging  in  extensive  pre-trial  discovery,  the  parties  engaged  in  a
mediation process that resulted in a non-binding settlement term sheet on September 21, 2020. On January 4, 2021, the parties executed and filed a Stipulation of
Settlement (the “Settlement Agreement”) with the Delaware Court of Chancery. The principal terms of the Settlement Agreement are as follows: (i) a $3.5 million
all-in cash settlement payment (the “Fund”) to be funded by defendants and/or their insurers into an escrow account, (ii) a bi-lateral complete and full release of all
claims against defendants and plaintiffs, and (iii) that 55% of the Fund (the derivative payment) be paid to Earthstone to be used as determined by management,
according  to  their  fiduciary  duties  and  business  judgment,  45%  of  the  Fund  (the  class  payment)  be  paid  to  members  of  the  class  or  current  stockholders  of
Earthstone. The Company expects court approval of the Settlement Agreement and in addition estimates the insurance carriers and related affiliates to reimburse
the Company in the amount of $2.8 million and $0.1 million, respectively. There is no assurance, however, that the court will approve the settlement. As described
above, the Company expects to receive a portion of the derivative payment, however, the amount cannot be reasonably determined at this time.

Through  December  31,  2020,  due  to  uncertainty  of  reimbursement,  the  Company  recorded  and  accrued  litigation  costs  when  incurred  and  recorded  insurance
reimbursements  as  an  offset  only  when  proceeds  were  received  in  Transactions  costs.  In  light  of  the  Settlement  Agreement,  insurance  carrier  agreement  on
allocation of defense costs and settlement payment combined with the history of reimbursements from insurance carriers and related affiliate, a high probability of
reimbursement exists. Accordingly, the Company has accrued $3.5 million related to the Settlement Agreement and estimated final defense costs associated with
this legal action included in Accrued expenses in the Consolidated Balance Sheets, offset by an accrued $3.1 million of estimated reimbursements from insurance
carriers and the majority shareholder which are included in Accounts receivable: Joint interest billings and other, net in the Consolidated Balance Sheets, with the
impact of both items included in Transaction costs in the Consolidated Statements of Operations.

Note 17. Income Taxes

The Company’s corporate structure requires the filing of two separate consolidated U.S. Federal income tax returns and one Canadian income tax return which
include  Lynden  US,  Earthstone,  and  Lynden  Corp.  As  such,  taxable  income  of  Earthstone  cannot  be  offset  by  tax  attributes,  including  net  operating  losses,  of
Lynden US, nor can taxable income of Lynden US be offset by tax attributes of Earthstone. Earthstone and Lynden US record a tax provision, respectively, for
their share of the book income or loss of EEH, net of the non-controlling interest. As EEH is treated as a partnership for U.S. Federal income tax purposes, it is not
subject to income tax at the federal level and only recognizes the Texas Margin Tax.

During the year ended December 31, 2020, the Company recorded total income tax benefit of $0.11 million which included (1) deferred income tax benefit for
Lynden US of $0.15 million as a result of its share of the distributable income from EEH, (2) deferred income tax benefit for Earthstone of $0.61 million as a result
of its share of the distributable loss from EEH, which was offset by a valuation allowance as future realization of the net deferred tax asset cannot be assured and
(3) current income tax expense of $0.55 million, offset by deferred income tax benefit of $0.51 million related to the Texas Margin Tax. Lynden Corp incurred no
material income or loss, or related income tax expense or benefit, for the year ended December 31, 2020.  

During the year ended December 31, 2019, the Company recorded total income tax expense of $1.7 million which included (1) deferred income tax expense for
Lynden US of $0.1 million as a result of its share of the distributable income from EEH, (2) deferred income tax expense for Earthstone of $0.4 million as a result
of its share of the distributable income from EEH, which was used to reduce the valuation allowance recorded against its deferred tax asset as future realization of
the  net  deferred  tax  asset  cannot  be  assured  and  (3)  deferred  income  tax  expense  of  $1.6  million  related  to  the  Texas  Margin  Tax.  Lynden  Corp  incurred  no
material income or loss, or related income tax expense or benefit, for the year ended December 31, 2019. 

Deferred Tax Assets and Liabilities

The Company’s deferred tax position reflects the net tax effects of the temporary differences between the carrying amounts of assets and liabilities for financial
reporting purposes and the amounts used for income tax reporting.  Significant components of the deferred tax assets and liabilities at December 31, 2020 and 2019
are as follows (in thousands):  

Deferred noncurrent income tax assets (liabilities):

Oil & gas properties
Basis difference in subsidiary obligation
Investment in Partnerships

As of December 31, 2020, the Company had a valuation allowance recorded against its deferred tax assets of $17.0 million which is in excess of its net deferred

EARTHSTONE ENERGY, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

Federal  corporate  income  tax  returns,  one  Canadian  income  tax  return  and  one  related  to  the  Texas  Margin  Tax  are  a  $13.3  million  deferred  tax  asset,  a  $9.6
million deferred tax liability, a $3.8 million deferred tax asset and a $4.8 million deferred tax liability, respectively, before considering the valuation allowance of
$17.0 million.

As of December 31, 2019, the Company had a valuation allowance recorded against its deferred tax assets of $16.5 million which is in excess of its Net deferred
noncurrent tax assets of $1.3 million, as presented above. The Company’s corporate organizational structure requires the filing of two separate consolidated U.S.
Federal income tax returns, one separate U.S. Federal partnership income tax return and one Canadian income tax return. As a result, tax attributes of one group
cannot be offset by the tax attributes of another. At December 31, 2019, the deferred tax assets and liabilities related to the two U.S. Federal income tax returns,
one Canadian income tax and one related to the Texas Margin Tax were a $12.7 million deferred tax asset, a $9.7 million deferred  tax liability, a $3.8 million
deferred tax asset and a $5.5 million deferred tax liability, respectively, before considering the valuation allowance of $16.5 million. 

As of December 31, 2020, the Company had estimated U.S. net operating loss carryforwards of $42.4 million, the first expiring in 2034 and the last in 2040, and
estimated Canadian net operating loss carryforwards of $10.0 million, the first expiring in 2024 and the last in 2037. The ability to utilize net operating losses and
other tax attributes could be subject to a significant limitation if the Company were to undergo an ownership change for the purposes of Section 382 (“Sec 382”) of
the Internal Revenue Code of 1986, as amended (the “Code”).  The Company has an additional estimated U.S. net operating loss carryforward of $28.2 million
limited by Sec 382 resulting from the Lynden Arrangement. The Company continues to evaluate the impact, if any, of potential Sec 382 limitations.

The Company’s tax returns are subject to periodic audits by the various jurisdictions in which the Company operates. These audits can result in adjustments of
taxes due or adjustments of the NOL carryforwards that are available to offset future taxable income. Generally, the Company’s income tax years 2014 through
2019 remain open and subject to examination by the Internal Revenue Service or state tax jurisdictions where it conducts operations. In certain jurisdictions, the
Company operates through more than one legal entity, each of which may have different open years subject to examination.

Uncertain Tax Positions

FASB  ASC  Topic  740,  Income Taxes (“ASC  740”)  prescribes  a  recognition  threshold  and  a  measurement  attribute  for  the  financial  statement  recognition  and
measurement of income tax positions taken or expected to be taken in an income tax return. For those benefits to be recognized, an income tax position must be
more-likely-than-not to be sustained upon examination by taxing authorities. As of December 31, 2020, the Company had no material uncertain tax positions. The
Company’s uncertain tax positions may change in the next twelve months; however, the Company does not expect any possible change to have a significant impact
on its results of operations or financial position.

The  Company  files  two  Federal  income  tax  returns,  one  Canadian  income  tax  return  and  various  combined  and  separate  filings  in  several  state  and  local
jurisdictions. The Company’s practice is to recognize estimated interest and penalties, if any, related to potential underpayment of income taxes as a component of
income tax expense in its Consolidated Statement of Operations. As of December 31, 2020, the Company did not have any accrued interest or penalties associated
with any uncertain tax liabilities.

Note 18. Defined Contribution Plan

The Company sponsors a 401(k) defined contribution plan (the “401(k) Plan”) for substantially all of its employees, which was initiated in April 2017. Eligible
employees may make contributions to the 401(k) Plan by electing to contribute up to 100% of their annual compensation, not to exceed annual limits established
by the federal government. The Company makes matching contributions of 100% of employee contributions, not to exceed six percent of the employee’s annual
eligible compensation. The Company’s matching contributions vest immediately. The Company’s contributions to the 401(k) Plan for the years ended December
31, 2020 and 2019 were $0.5 million and $0.5 million, respectively.

Note 19. Leases

The Company’s operating lease activities consist of leases for office space. The Company’s finance lease activities consist of leases for vehicles. Leases with an
initial term of 12 months or less are not recorded on the balance sheet. Most leases include one or more options to renew, with renewal terms generally ranging
from one to  three  years.  The  exercise  of  lease  renewal  options  is  at  the  Company’s  sole  discretion.  Certain  leases  also  include  options  to  purchase  the  leased
property.  The  depreciable  life  of  assets  and  leasehold  improvements  is  limited  by  the  expected  lease  term,  unless  there  is  a  transfer  of  title  or  purchase  option
reasonably  certain  of exercise.  None of the  lease  agreements  include variable  lease  payments. The lease  agreements  do not contain  any material  residual  value
guarantees or material restrictive covenants.

Users  of  this  information  should  be  aware  that  the  process  of  estimating  quantities  of  “proved”  and  “proved  developed”  oil  and  natural  gas  reserves  is  very
complex, requiring significant subjective decisions in the evaluation of all available geological, engineering and economic data for each reservoir. The data for a
given reservoir  may also change substantially  over time as a result of numerous factors including, but not limited to, additional development  activity, evolving
production history and continual reassessment of the viability of production under varying economic conditions. As a result, revisions to existing reserve estimates
may occur from time to time. Although every reasonable effort is made to ensure reserve estimates reported represent the most accurate assessments possible, the
subjective decisions and variances in available data for various reservoirs make these estimates generally less precise than other estimates included in the financial
statement disclosures.

Proved  reserves  represent  estimated  quantities  of  oil,  natural  gas  and  natural  gas  liquids  that  geological  and  engineering  data  demonstrate,  with  reasonable
certainty,  to  be  recoverable  in  future  years  from  known  reservoirs  under  economic  and  operating  conditions  in  effect  when  the  estimates  were  made.  Proved
developed  reserves  represent  estimated  quantities  expected  to  be  recovered  through  wells  and  equipment  in  place  and  under  operating  methods  used  when  the
estimates were made.

The  proved  reserves  estimates  shown  herein  for  the  years  ended  December  31,  2020  and  2019  have  been  prepared  by  Cawley,  Gillespie  &  Associates,  Inc.,
independent petroleum engineers. Proved reserves were estimated in accordance with guidelines established by the SEC, which require that reserve estimates be
prepared under existing economic and operating conditions based upon the 12-month unweighted average of the first-day-of-the-month prices.

The reserve information in these Consolidated Financial Statements represents only estimates. There are a number of uncertainties inherent in estimating quantities
of proved reserves, including many factors beyond the Company’s control, such as commodity pricing. Reserve engineering is a subjective process of estimating
underground accumulations of oil and natural gas that cannot be measured in an exact manner. The accuracy of any reserve estimate is a function of the quality of
available data and engineering and geological interpretation and judgment. As a result, estimates by different engineers may vary. In addition, results of drilling,
testing and production subsequent to the date of an estimate may lead to revising the original estimate. Accordingly, initial reserve estimates are often different
from the quantities of oil and natural gas that are ultimately recovered. The meaningfulness of such estimates depends primarily on the accuracy of the assumptions
upon which they were based. Except to the extent the Company acquires additional properties containing proved reserves or conducts successful exploration and
development activities or both, the Company’s proved reserves will decline as reserves are produced.

The following table illustrates the Company’s estimated net proved reserves, including changes, and proved developed and proved undeveloped reserves for the
periods indicated. The oil prices as of December 31, 2020 and 2019 are based on the

30

 
 
 
 
respective 12-month unweighted average of the first of the month prices of the West Texas Intermediate (“WTI”) spot prices which equates to $39.57 per barrel
and $55.69 per barrel, respectively. The natural gas prices as of December 31, 2020 and 2019 are based on the respective 12-month unweighted average of the first
of month prices of the Henry Hub spot price which equates to $1.99 per MMBtu and $2.58 per MMBtu, respectively. Natural gas liquids are made up of ethane,
propane, isobutane, normal butane and natural gasoline, each of which have different uses and different pricing characteristics. The natural gas liquids prices used
to value reserves as of December 31, 2020 and 2019 averaged $11.61 per barrel and $16.17 per barrel, respectively. All prices are adjusted by lease or field for
energy content, transportation fees, and market differentials, resulting in the aforementioned oil, natural gas and natural gas liquids reserves as of December 31,
2020 being valued using prices of $38.90 per barrel, $0.97 per MMBtu and $11.61 per barrel, respectively. All prices are held constant in accordance with SEC
guidelines.    

A  summary  of  the  Company’s  changes  in  quantities  of  proved  oil,  natural  gas  and  NGLs  reserves  for  the  years  ended  December  31,  2020  and  2019  are  as

Notable changes in proved reserves for the year ended December 31, 2020 included the following:

•

Extensions  and  discoveries. In  2020,  total  extensions  and  discoveries  of  860.0  MBOE  was  the  result  of  successful  drilling  results  and  well
performance primarily related to the Midland Basin.

31

•

Revision to previous estimates. In 2020, the downward revisions of prior reserves of 10.7 MMBOE were primarily due to negative revisions due
to  price  which  included  the  reclassification  of  11.9  MMBOE  of  reserves  from  proved  undeveloped  to  non-proved  due  to  the  five-year
development rule.

Notable changes in proved reserves for the year ended December 31, 2019 included the following:

•

•

•

Extensions  and  discoveries. In  2019,  total  extensions  and  discoveries  of  5.1  MMBOE  was  a  result  of  successful  drilling  results  and  well
performance primarily related to the Midland Basin.

Sales of minerals in place. Sales of minerals in place totaled  32.0 MBOE during 2019, resulting from the disposition  of certain  non-operated
properties in the Midland Basin. See Note 3. Acquisitions and Divestitures.

Revision to previous estimates. In 2019, the downward revisions of prior reserves  of 4.6 MMBOE were primarily  due to reduced commodity
prices.

For wells classified as proved developed producing where sufficient production history existed, reserves were based on individual well performance evaluation and
production decline curve extrapolation techniques. For undeveloped locations and wells that lack sufficient production history, reserves were based on analogy to
producing wells within the same area exhibiting similar geologic and reservoir characteristics. Well spacing was determined from drainage patterns derived from a
combination of performance-based recoveries and analogous producing wells for each area or field. PUD locations were limited to areas of uniformly high-quality
reservoir properties, between existing commercial producers where the reservoir can, with reasonable certainty, be judged to be continuous with existing producers
and contain economically producible oil and natural gas on the basis of available geoscience and engineering data.  

Changes in PUD reserves for the years ended December 31, 2020 and 2019 were as follows (in MBOE):

Conversions to developed. In our year-end 2019 plan to develop its PUDs within five years, we estimated that $111.1 million of capital would be expended in 2020
for the conversion of 28 gross / 17.6 net PUDs to add 11.3 MMBOE. In 2020, due to unforeseeable conditions previously described, we spent $67.8 million to
convert 18 gross / 10.3 net PUDs adding 8.2 MMBOE to developed.

Revision to previous estimates. We maintain a five-year development plan, reviewed annually to ensure capital is allocated to the wells that have the highest risk-
adjusted rates of return within our inventory of undrilled well locations. In response to lower commodity prices, we reduced the pace of activity in our five-year
development plan. This resulted in the reclassification of 11.9 MMBOE of reserves from proved undeveloped to non-proved during the year ended December 31,
2020 due to the five-year development rule. Based on our then-current acreage position, strip prices, anticipated well economics, and our development plans at the
time  these  reserves  were  classified  as  proved,  we  believe  the  previous  classification  of  these  locations  as  proved  undeveloped  was  appropriate.  The  remaining
revisions of 2.1 MMBOE were primarily due to reduced commodity prices.

2019 Changes in Proved Undeveloped Reserves

Conversions to developed.  In  the  Company’s  year-end  2018  plan  to  develop  its  PUDs  within  five  years,  the  Company  estimated  that  $103.8  million  of  capital
would be expended in 2019 for the conversion of 30 gross / 12.30 net PUDs to add 9.9 MMBOE,

32

which was consistent with the $111.5 million actually spent to convert 32 gross / 13.4 net PUDs adding 10.3 MMBOE to developed.

Extensions  and  discoveries.  Additionally,  1.2  MMBOE  were  added  as  extensions  and  discoveries  due  to  successful  drilling  results  on  the  Company’s  acreage
positions because of the wells it drilled. The increase was also supported by successful drilling results by other operators directly offsetting and in close proximity
to the Company’s acreage.

Revision to previous estimates. Revisions of 3.4 MMBOE were primarily due to reduced commodity prices. 

Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil and Natural Gas Reserves

The  following  Standardized  Measure  of  Discounted  Future  Net  Cash  Flows  (Standardized  Measure)  has  been  developed  utilizing  FASB  ASC  Topic  932,
Extractives Activities – Oil and Gas (“ASC 932”) procedures and based on oil and natural gas reserve and production volumes estimated by the Company’s third-
party  petroleum  engineering  firm.  It  can  be  used  for  some  comparisons,  but  should  not  be  the  only  method  used  to  evaluate  the  Company  or  its  performance.
Further, the information in the following table may not represent realistic assessments of future cash flows, nor should the Standardized Measure be viewed as
representative of the current value of the Company.

The Company believes that the following factors should be taken into account when reviewing the following information:

Future costs and commodity prices will probably differ from those required to be used in these calculations;

Due to future market conditions and governmental regulations, actual rates of production in future years may vary significantly from the rate of
production assumed in the calculations;

A 10% discount rate may not be reasonable as a measure of the relative risk inherent in realizing future net oil and natural gas revenues; and

Future net revenues may be subject to different rates of income taxation.

At December 31, 2020 and 2019, as specified by the SEC, the prices for oil and natural gas used in this calculation were the unweighted 12-month average of the
first day of the month prices, except for volumes subject to fixed price contracts. Prices used to estimate reserves are included in Oil and Natural Gas Reserves
above. Future production costs include per-well overhead expenses allowed under joint operating agreements, abandonment costs (net of salvage value), and a non-
cancelable  fixed  cost  agreement  to  reserve  pipeline  capacity  of  10,000  MMBtu  per  day  for  gathering  and  processing.  Estimates  of  future  income  taxes  are
computed using current statutory income tax rates including consideration for estimated future statutory depletion and tax credits. The resulting net cash flows are
reduced to present value amounts by applying a 10% discount factor.

The Standardized Measure is as follows (in thousands):

Future cash inflows
Future production costs
Future development costs
Future income tax expense
Future net cash flows
10% annual discount for estimated timing of cash flows

            Reserves and Future Net Revenue
Dear Mr. Vernon:

As you have requested, this report was completed on January 15, 2021 for the purpose of submitting our estimates of proved reserves and
forecasts  of  economics  attributable  to  the  Earthstone  Energy,  Inc.  (“Earthstone”)  interests.  This  report  covers  all  of  Earthstone’s  proved
reserves. We evaluated 100% of Earthstone’s reserves, which are made up of oil and gas properties in various counties within the State of
Texas.  This  report  utilized  an  effective  date  of  December  31,  2020,  was  prepared  using  constant  prices  and  costs,  and  conforms  to  Item
1202(a)(8)  of  Regulation  S-K  and  other  rules  of  the  Securities  and  Exchange  Commission  (“SEC”).  This  report  was  prepared  for  the
inclusion as an exhibit in a filing made with  the SEC. The results of this evaluation are presented in the accompanying tabulation, with a
composite summary of the values presented below:

Future revenue is prior to deducting state production taxes and ad valorem taxes. Future net cash flow is after deducting these taxes,
future capital costs and operating expenses, but before consideration of federal income taxes. In accordance with SEC guidelines, the future
net cash flow has been discounted at an annual rate of ten percent to determine its “present worth”. The present worth is shown to indicate the
effect  of  time  on  the  value  of  money  and  should  not  be  construed  as  being  the  fair  market  value  of  the  reserves  by  Cawley,  Gillespie  &
Associates,  Inc.  (“CG&A”).The  oil  reserves  include  oil  and  condensate.  Oil  volumes  and  NGL  volumes  are  expressed  in  barrels  (42  U.S.
gallons). Gas volumes are expressed in thousands of standard cubic feet (Mcf) at contract temperature and pressure base.

Hydrocarbon Pricing

As  requested  for  SEC  purposes,  the  base  oil  and  gas  prices  calculated  for  December  31,  2020  were  $39.57/BBL  and
$1.985/MMBTU,  respectively.  As  specified  by  the  SEC,  a  company  must  use  a  12-month  average  price,  calculated  as  the  unweighted
arithmetic average of the first-day-of-the-month price for each month within the 12-month period prior to the end of the reporting period. The
base oil price is based upon WTI-Cushing spot prices (EIA) during 2020 and the base gas price is based upon Henry Hub spot prices (Platts
Gas Daily) during 2020. NGL prices were adjusted on a per-property basis and averaged 29.3% of the net oil price on a composite basis.

The  base  prices  were  adjusted  for  differentials  on  a  per-property  basis,  which  may  include  local  basis  differential,  treating  cost,
transportation, gas shrinkage, gas heating value (BTU content) and/or crude quality and gravity corrections. After these adjustments, the net
realized prices for the SEC price case over the life of the proved properties was estimated to be $38.90 per barrel for oil, $0.97 per MCF for
natural gas and $11.61per barrel for NGL. All economic factors were held constant in accordance with SEC guidelines.

Capital, Expenses and Taxes
    Capital expenditures, lease operating expenses and ad valorem tax values were forecast as provided by Earthstone. As you explained, the
capital  costs  were  based  on  the  most  current  estimates,  lease  operating  expenses  were  based  on  the  analysis  of  historical  actual  expenses,
operating overhead is included for nonoperated properties and no credit or deduction is made for producing overhead paid to the company by
other owners of the operated properties. Capital costs and lease operating expenses were held constant in accordance with SEC guidelines.
Severance tax rates were applied at normal state percentages of oil and gas revenue. Severance tax rates in certain instances, where authorized
by taxing authorities, have severance tax abatements and were provided by your office and applied when appropriate.

SEC Conformance and Regulations
    The reserve classifications and the economic considerations used herein conform to the criteria of the SEC as defined in pages 3 and 4 of
the  Appendix.  The  reserves  and  economics  are  predicated  on  regulatoryagency  classifications,  rules,  policies,  laws,  taxes  and  royalties
currently  in  effect  except  as  noted  herein.  Federal,  state,  and  local  laws  and  regulations,  which  are  currently  in  effect  and  that  govern  the
development and production of oil and natural gas, have been considered in the evaluation of proved reserves for this report. The possible
effects  of  changes  in  legislation  or  other  Federal  or  State  restrictive  actions  which  could  affect  the  reserves  and  economics  have  not  been
considered. These possible changes could have an effect on the reserves and economics. However, we do not anticipate nor are we aware of
any legislative changes or restrictive regulatory actions that may impact the recovery of reserves.

This  evaluation  includes  69  proved  undeveloped  locations,  67  of  which  are  commercial  using  required  SEC  pricing.  Each  of  these
commercial drilling locations proposed as part of Earthstone’s development plans conforms to the proved undeveloped standards as set forth
by  the  SEC.  In  our  opinion,  Earthstone  has  indicated  it  has  every  intent  to  complete  this  development  plan  as  scheduled.  Furthermore,
Earthstone  has  demonstrated  that  it  has  adequate  company  staffing,  financial  backing  and  prior  development  success  to  ensure  this
development plan will be fully executed.

Reserve Estimation Methods
    The methods employed in estimating reserves are described on page 2 of the Appendix. Reserves for proved developed producing wells
were estimated using production performance methods for the vast majority of properties. Certain new producing properties with very little
production  history  were  forecast  using  a  combination  of  production  performance  and  analogy  to  similar  production,  both  of  which  are
considered to provide a relatively high degree of accuracy.

Non-producing  reserve  estimates,  including  undeveloped  properties,  were  forecast  using  either  volumetric  or  analogy  methods,  or  a
combination  of  both.  These  methods  provide  a  relatively  high  degree  of  accuracy  for  predicting  proved  undeveloped  reserves.  The
assumptions, data, methods and procedures used herein are appropriate for the purpose served by this report.

Miscellaneous
    An on-site field inspection of the properties has not been performed nor has the mechanical operation or condition of the wells and their
related  facilities  been  examined,  nor  have  the  wells  been  tested  by  Cawley,  Gillespie  &  Associates,  Inc.  Possible  environmental  liability
related to the properties has not been investigated nor considered. However, the estimated costs of plugging and abandoning wells have been
included herein as provided.

    The reserve estimates and forecasts were based upon interpretations of data furnished by Earthstoneand available from our files. Ownership
information  and  economic  factors  such  as  liquid  and  gas  prices,  price  differentials  and  expenses  were  furnished  by  Earthstone.  To  some
extent, information from public records was

Earthstone Energy, Inc. Interests
January 15, 2021
Page 4

used to check and/or supplement these data. The basic engineering and geological data were utilized subject to third party reservations and
qualifications. Nothing has come to our attention, however, that would cause us to believe that we are not justified in relying on such data. All
estimates represent our best judgment based on the data available at the time of preparation. Due to inherent uncertainties in future production
rates, commodity prices and geologic conditions, it should be realized that the reserve estimates, the reserves actually recovered, the revenue

Methods Employed in the Estimation of Reserves

The four methods customarily employed in the estimation of reserves are (1) production performance, (2) material balance, (3) volumetric and (4) analogy. Most

estimates, although based primarily on one method, utilize other methods depending on the nature and extent of the data available and the characteristics of the reservoirs.

Basic information includes production, pressure, geological and laboratory data. However, a large variation exists in the quality, quantity and types of information
available on individual properties. Operators are generally required by regulatory authorities to file monthly production reports and may be required to measure and report
periodically such data as well pressures, gas-oil ratios, well tests, etc. As a general rule, an operator has complete discretion in obtaining and/or making available geological
and  engineering  data.  The  resulting  lack  of  uniformity  in  data  renders  impossible  the  application  of  identical  methods  to  all  properties,  and  may  result  in  significant
differences in the accuracy and reliability of estimates.

A brief discussion of each method, its basis, data requirements, applicability and generalization as to its relative degree of

accuracy follows:

Production performance. This method employs graphical analyses of production data on the premise that all factors which have controlled the performance to date will
continue to control and that historical trends can be extrapolated to predict future performance. The only information required is production history. Capacity production can
usually be analyzed from graphs of rates versus time or cumulative production. This procedure is referred to as "decline curve" analysis. Both capacity and restricted production
can, in some cases, be analyzed from  graphs of  producing  rate relationships  of  the various production  components. Reserve estimates  obtained by  this  method are generally
considered to have a relatively high degree of accuracy with the degree of accuracy increasing as production historyaccumulates.

Material balance. This method employs the analysis of the relationship of production and pressure performance on the premise that the reservoir volume and its initial
hydrocarbon content are fixed and that this initial hydrocarbon volume and recoveries therefrom can be estimated by analyzing changes in pressure with respect to production
relationships. This method requires reliable pressure and temperature data, production data, fluid analyses and knowledge of the nature of the reservoir. The material balance
method  is  applicable  to  all  reservoirs,  but  the  time  and  expense  required  for  its  use  is  dependent  on  the  nature  of  the  reservoir  and  its  fluids.  Reserves  for  depletion  type
reservoirs can be estimated from graphs of pressures corrected for compressibility versus cumulative production, requiring only data that are usually available. Estimates for
other reservoir types require extensive data and involve complex calculations most suited to computer models which makes this method generally applicable only to reservoirs
where there is economic justification for its use. Reserve estimates obtained by this method are generally considered to have a degree of accuracy that is directly related to the
complexity of the reservoir and the quality and quantity of data available.

Volumetric. This method employs analyses of physical measurements of rock and fluid properties to calculate the volume of hydrocarbons in-place. The data required
are  well  information  sufficient  to  determine  reservoir  subsurface  datum,  thickness,  storage  volume,  fluid  content  and  location.  The  volumetric  method  is  most  applicable  to
reservoirs  which  are  not  susceptible  to  analysis  by  production  performance  or  material  balance  methods.  These  are  most  commonly  newly  developed  and/or  no-pressure
depleting reservoirs. The amount of hydrocarbons in-place that can be recovered is not an integral part of the volumetric calculations but is an estimate inferred by other methods
and a knowledge of the nature of the reservoir. Reserve estimates obtained by this method are generally considered to have a low degree of accuracy; but the degree of accuracy
can be relatively high where rock quality and subsurface control is good and the nature of the reservoir is uncomplicated.

Analogy.  This  method,  which  employs  experience  and  judgment  to  estimate  reserves,  is  based  on  observations  of  similar  situations  and  includes  consideration  of
theoretical  performance.  The  analogy  method  is  a  common  approach  used  for  “resource  plays,”  where  an  abundance  of  wells  with  similar  production  profiles  facilitates  the
reliable estimation of future reserves with a relatively high degree of accuracy. The analogy method may also be applicable where the data are insufficient or so inconclusive that
reliable reserve estimates cannot be made by other methods. Reserve estimates obtained in this manner are generally considered to have a relatively low degree of accuracy.

Much of the information used in the estimation of reserves is itself arrived at by the use of estimates. These estimates are subject to continuing change as additional
information becomes available. Reserve estimates which presently appear to be correct may be found to contain substantial errors as time passes and new information is obtained
about well and reservoir performance.

Reserve Definitions and Classifications

The  Securities  and  Exchange  Commission,  in  SX  Reg.  210.4-10  dated  November  18,  1981,  as  amended  on  September  19,  1989  and  January  1,  2010,  requires

adherence to the following definitions of oil and gas reserves:

"(22) Proved oil and gas reserves. Proved oil and gas reserves are those quantities of oil and 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.

"(i) The area of a reservoir considered as proved includes: (A) The area identified by drilling and limited by fluid contacts, if any, and (B) Adjacent undrilled
portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically producible oil or gas on the basis of available
geoscience and engineering data.

"(ii) In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons (LKH) as seen in a well penetration

unless geoscience, engineering, or performance data and reliable technology establishes a lower contact with reasonable certainty.

"(iii) Where direct observation from well penetrations has defined a highest known oil (HKO) elevation and the potential exists for an associated gas cap, proved
oil reserves may be assigned in the structurally higher portions of the reservoir only if geoscience, engineering, or performance data and reliable technology establish the
higher contact with reasonable certainty.

"(iv)  Reserves  which  can  be  produced  economically  through  application  of  improved  recovery  techniques  (including,  but  not  limited  to,  fluid  injection)  are
included in the proved classification when: (A) Successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a
whole, the operation of an installed program in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes the reasonable certainty of the
engineering  analysis  on  which  the  project  or  program  was  based;  and  (B)  The  project  has  been  approved  for  development  by  all  necessary  parties  and  entities,
includinggovernmental entities.

"(v) Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price shall be the average
price during the 12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month
price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.

"(6) Developed oil and gas reserves. Developed oil and gas reserves are reserves of any category that can be expected to be recovered:

“(i) Through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the

cost of a new well; and

“(ii) Through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well.

"(31)     Undeveloped oil and gas reserves. Undeveloped oil and gas reserves are reserves of any category 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.

“(i) Reserves on undrilled acreage shall be limited to those directly offsetting development spacing areas that are reasonably certain of production when drilled,

unless evidence using reliable technology exists that establishes reasonable certainty of economic producibility at greater distances.

“(ii) Undrilled locations can be classified as having undeveloped reserves only if a development plan has been adopted indicating that they are scheduled to be

drilled within five years, unless the specific circumstances, justify a longer time.

“(iii) Under no circumstances shall estimates for undeveloped reserves be attributable to any acreage for which an application of fluid injection or other improved
recovery  technique  is  contemplated,  unless  such  techniques  have  been  proved  effective  by  actual  projects  in  the  same  reservoir  or  an  analogous  reservoir,  as  defined  in
paragraph (a)(2) of this section, or by other evidence using reliable technology establishing reasonable certainty.

"(18)    Probable reserves. Probable reserves are those additional reserves that are less certain to be recovered than proved reserves but which, together with

proved reserves, are as likely as not to be recovered.

“(i) When deterministic methods are used, it is as likely as not that actual remaining quantities recovered will exceed the sum of estimated proved plus probable
reserves. When probabilistic methods are used, there should be at least a 50% probability that the actual quantities recovered will equal or exceed the proved plus probable
reserves estimates.

“(ii) Probable reserves may be assigned to areas of a reservoir adjacent to proved reserves where data control or interpretations of available data are less certain,
even if the interpreted reservoir continuity of structure or productivity does not meet the reasonable certainty criterion. Probable reserves may be assigned to areas that are
structurally higher than the proved area if these areas are in communication with the proved reservoir.

“(iii) Probable reserves estimates also include potential  incremental  quantities  associated with a greater percentage recovery of the hydrocarbons  in place than

assumed for proved reserves.

“(iv)    See also guidelines in paragraphs (17)(iv) and (17)(vi) of this section (below).

reserves.

"(17)    Possible reserves. Possible reserves are those additional reserves that are less certain to be recovered than probable

“(i)    When deterministic methods are used, the total quantities ultimately recovered from a project have a low probability of exceeding proved plus probable
plus possible reserves. When probabilistic methods are used, there should be at least a 10% probability that the total quantities ultimately recovered will equal or exceed the
proved plus probable plus possible reserves estimates.

“(ii)  Possible  reserves  may  be  assigned  to  areas  of  a  reservoir  adjacent  to  probable  reserves  where  data  control  and  interpretations  of  available  data  are
progressively  less  certain.  Frequently,  this  will  be  in  areas  where  geoscience  and  engineering  data  are  unable  to  define  clearly  the  area  and  vertical  limits  of  commercial
production from the reservoir by a defined project.

“(iii) Possible reserves also include incremental quantities associated with a greater percentage recovery of the hydrocarbons in place than the recovery quantities

assumed for probable reserves.

“(iv)  The  proved  plus  probable  and  proved  plus  probable  plus  possible  reserves  estimates  must  be  based  on  reasonable  alternative  technical  and  commercial

interpretations within the reservoir or subject project that are clearly documented, including comparisons to results in successful similar projects.

“(v) Possible reserves may be assigned where geoscience and engineering data identify directly adjacent portions of a reservoir within the same accumulation that
may  be  separated  from  proved  areas  by  faults  with  displacement  less  than  formation  thickness  or  other  geological  discontinuities  and  that  have  not  been  penetrated  by  a
wellbore, and the registrant believes that such adjacent portions are in communication with the known (proved) reservoir. Possible reserves may be assigned to areas that are
structurally higher or lower than the proved area if these areas are in communication with the proved reservoir.

“(vi) Pursuant to paragraph (22)(iii) of this section (above), where direct observation has defined a highest known oil (HKO) elevation and the potential exists for
an associated gas cap, proved oil reserves should be assigned in the structurally higher portions of the reservoir above the HKO only if the higher contact can be established
with reasonable certainty through reliable technology. Portions of the reservoir that do not meet this reasonable certainty criterion may be assigned as probable and possible
oil or gas based on reservoir fluid properties and pressure gradient interpretations.”

Instruction 4 of Item 2(b) of Securities and Exchange Commission Regulation S-K was revised January 1, 2010 to state that "a registrant engaged in oil and gas
producing activities shall provide the information required by Subpart 1200 of Regulation S-K." This is relevant in that Instruction 2 to paragraph (a)(2) states: “The registrant
is permitted, but not required, to disclose probable or possible reserves pursuant to paragraphs (a)(2)(iv) through (a)(2)(vii) of this Item.”

"(26) Reserves. Reserves are estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by
application of development projects to known accumulations. In addition, there must exist, or there must be a reasonable expectation that there will exist, the legal right to
produce or a revenue interest in the production, installed means of delivering oil and gas or related substances to market, and all permits and financing required to implement
the project.

“Note to paragraph (26): Reserves should not be assigned to adjacent reservoirs isolated by major, potentially sealing, faults until those

productive reservoir (i.e., absence of reservoir, structurally low reservoir, or negative test results). Such areas may contain prospective resources (i.e., potentially recoverable
resources from undiscovered accumulations).”
