The ratio does not assume priceequivalency 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 barrelof 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 ofoil 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 productionfacilities.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 hasa 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 tofuture assignment, the working interest or a portion thereof to another party who desires to drill on the leased acreage. Generally, the farmee is required todrill 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 interestreceived 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/orstratigraphic condition.Gross acres or gross wells – The total acres or wells, as the case may be, in which a working interest is owned.HBP – Held by production, a mineral lease provision that extends the right to operate and maintain a lease as long as the property produces a minimumquantity of oil and/or natural gas.Horizontal drilling – A drilling technique that permits the operator to drill horizontally within a specified targeted reservoir and thus exposes a larger portionof 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 holdopen 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 afracture 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 sufficientpressure to produce the recoverable reserves.Joint Development Agreement or JDA – An agreement that provides for the joint development of a tract of land typically utilized after the leasing phase hasconcluded or when minerals are HBP.Joint Operating Agreement or JOA – Any agreement between working interest owners concerning the duties and responsibilities of the operator and rightsand obligations of the non-operators.MBbls – One thousand barrels of crude oil or other liquid hydrocarbons.5Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

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 equipmentand operating methods.Proved developed reserves or PD – The estimated quantities of oil, natural gas and NGLs that geological and engineering data demonstrate with reasonablecertainty 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 certaintyto be economically producible—from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, andgovernment regulations—prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonablycertain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must havecommenced or the operator must be reasonably certain that it will commence the project within a reasonable time. The area of the reservoir considered asproved includes (i) the area identified by drilling and limited by fluid contacts, if any, and (ii) adjacent undrilled portions of the reservoir that can, withreasonable certainty, be judged to be continuous with it and to contain economically producible oil or gas on the basis of available geoscience andengineering data. In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons (“LKH”), as seen ina well penetration unless geoscience, engineering, or performance data and reliable technology establishes a lower contact with reasonable certainty. Wheredirect observation from well penetrations has defined a highest known oil (“HKO”), elevation and the potential exists for an associated gas cap, proved oilreserves may be assigned in the structurally higher portions of the reservoir only if geoscience, engineering, or performance data and reliable technologyestablish 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 reservoirwith 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 otherevidence using reliable technology establishes the reasonable certainty of the engineering analysis on which the project or program was based; and (ii) theproject has been approved for development by all necessary parties and entities, including governmental entities. Existing economic conditions includeprices 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 priorto the ending date of the period covered by the report, determined as an unweighted6Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Reserves on undrilled acreage shall be limited to those directly offsetting development spacingareas that are reasonably certain of production when drilled, unless evidence using reliable technology exists that establishes reasonable certainty ofeconomic producibility at greater distances. Undrilled locations can be classified as having undeveloped reserves only if a development plan has beenadopted indicating that they are schedule to be drilled within five years unless specific circumstances justify a longer time. Under no circumstances shallestimates for proved undeveloped reserves be attributable to any acreage for which an application of fluid injection or other improved recovery technique iscontemplated, unless such techniques have been proved effective by actual projects in the same reservoir or an analogous reservoir, or by other evidenceusing 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 andmodify down hole artificial lift equipment and surface equipment and facilities. The programs are designed specifically for individual fields to increase andmaintain 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 rockor 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 notproducing due to market conditions, mechanical difficulties or because production equipment or pipelines were not yet installed. These reserves are includedin the PDNP category in our reserve report.Slickwater – A method of hydraulic fracturing that predominately uses water and chemicals, with sand, that is injected into an oil or natural gas reservoir tocreate a fracture in the reservoir rock and create or enhance fluid flow.Standardized Measure - The present value of estimated future net revenue to be generated from the production of proved reserves, determined in accordancewith 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 taxexpenses, 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 commercialquantities 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 operatingactivities on the property and share in the sale of production, subject to all royalties, overriding royalties and other burdens and obligates the owner of theinterest 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.7Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

BusinessOverviewEarthstone Energy, Inc., a Delaware corporation (“Earthstone” and together with our consolidated subsidiaries, the “Company,” “our,” “we,” “us,” or similarterms), is a growth-oriented independent oil and gas company engaged in the acquisition and development of oil and gas reserves through activities thatinclude the acquisition, drilling and development of undeveloped leases, asset and corporate acquisitions and mergers. Our operations are all in the upstreamsegment of the oil and natural gas industry and all our properties are onshore in the United States. At present, our primary assets are located in the MidlandBasin 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 horizontaltargets with proven production results, long-lived reserves and historically high drilling success rates. During 2018, we used one drilling rig and successfullydrilled 16 wells in the Midland Basin with an average working interest of 89%. We completed 19 Midland Basin wells during 2018, including three wellsthat came online at the end of December 2018. With 866 potential gross horizontal drilling locations in the Midland Basin, we are focused on developmentaldrilling and completion operations in the area. We currently plan to maintain a one-rig drilling program on our operated acreage in the Midland Basin andexpect to drill approximately 16 wells in 2019. Additionally, we continue to pursue acreage trades in the southern Midland Basin with the intent ofincreasing our operated acreage and drilling inventory, drilling and completing longer laterals and realizing greater operating efficiency.We also own certain assets in the Eagle Ford Trend of south Texas where we have locations in the Eagle Ford and Austin Chalk formations. During 2018, wedrilled five Eagle Ford wells with an average working interest of 17% and completed 11 wells (five wells with a 17% working interest and six wells with a25% working interest). We expect to drill seven wells, with an average working interest of 22%, in this area during 2019 and may consider additional drillingbased on improvements in oil and natural gas commodity prices. We have 67 potential gross operated drilling locations in the Eagle Ford Trend for futuredevelopment.We have approximately 29,500 net acres in the core of the Midland Basin, of which 77% is operated and 23% is non-operated. Upon finalization ofdocuments for an agreed-upon mineral lease in Reagan County, which is expected to occur in the first quarter of 2019, we will have approximately 30,200net acres in the core of the Midland Basin. We hold an approximate 94% working interest in our operated acreage and an approximate 40% working interestin our non-operated acreage. Our operated acreage in the Midland Basin is primarily located in Reagan, Upton and Midland counties. Our non-operatedacreage in the Midland Basin is located primarily in Howard, Glasscock, Martin, Midland and Reagan counties. In total, we have an interest in 192 grossproducing wells in the Midland Basin. We have approximately 14,300 net leasehold acres in the Eagle Ford Trend, which primarily consists ofapproximately 14,100 operated net leasehold acres in the crude oil window in Fayette, Gonzales and Karnes counties, with working interests ranging fromapproximately 17% to 67%. We have an interest in 106 gross operated producing wells and six gross non-operated producing wells in the Eagle Ford Trend. At December 31, 2018, our estimated proved oil and natural gas reserves were approximately 98,847 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, 2018, our proved reserve quantities wereapproximately 60% oil, 19% natural gas, 21% NGLs with 24% of those reserves classified as proved developed. The calculated percentages include proveddeveloped non-producing reserves. Of these interests, approximately 54,628 MBOE are attributable to noncontrolling interests. See Note 9. NoncontrollingInterest in the Notes to Consolidated Financial Statements.Our Business StrategyOur current business strategy is to focus on the economic development of our existing acreage, increase our acreage and horizontal well locations in theMidland Basin and increase stockholder value through the following:•pursue value-accretive acquisition and corporate merger opportunities, which could increase the scale of our operations;•profitably increase cash flows, production and reserves by selectively developing our acreage base;•expand our acreage positions and drilling inventory in our areas of primary interest through acquisitions and farm-in opportunities, with anemphasis on operated positions;•block up acreage to allow for 10,000-foot (or longer) horizontal lateral drilling locations which provide higher economic returns;•maintain operating control over the majority of our production, development and undeveloped acreage; and8Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results.•maintain a strong balance sheet and financial flexibility.Our StrengthsWe believe that the following strengths will be beneficial in achieving our business goals:•extensive horizontal development potential in one of the most oil rich basins of the United States;•experienced management team with substantial technical and operational expertise and a history of successful acquisition and mergertransactions;•operating control over the majority of our production and development activities; and•conservative balance sheet.Recent DevelopmentsTerminated Contribution AgreementAs previously disclosed in our Current Report on Form 8-K filed on October 17, 2018 with the SEC, on October 17, 2018, Earthstone, Earthstone EnergyHoldings, LLC (“EEH”) and Sabalo Holdings, LLC (“Sabalo Holdings”) entered into a contribution agreement (the “Contribution Agreement”) whichprovided for the contribution by Sabalo Holdings of all its interests in Sabalo Energy, LLC (“Sabalo Energy”) and Sabalo Energy, Inc. to EEH (the “SabaloAcquisition”). On December 21, 2018, Earthstone, EEH and Sabalo Holdings entered into a termination agreement (the “Termination Agreement”), pursuantto which the parties mutually terminated the Contribution Agreement.In connection with the Termination Agreement, Earthstone, EEH and Sabalo Holdings also agreed to release each other from certain claims and liabilitiesarising out of or related to the Contribution Agreement and the transactions contemplated therein or thereby. In addition, we estimated total transaction coststo be approximately $13.4 million, including payment to Sabalo Holdings of $1.6 million for reimbursement of its expenses. All other related agreementswere also terminated in conjunction with the termination of the Contribution Agreement.Midland Basin Acreage TradeOn October 5, 2018, we closed a transaction in the Midland Basin that included producing properties and undeveloped acreage (the "Exchange"). Under theterms of the Exchange, we acquired 3,899 net operated acres in Reagan County with virtually a 100% working interest, in exchange for 1,222 net non-operated acres in Glasscock County with an average working interest of 39% and $27.8 million in cash, subject to customary closing adjustments. Theeffective date of the transaction was September 1, 2018.Along with the net increase of 2,677 acres, the Exchange also resulted in a net production increase of approximately 350 Boe/d. The producing wellsacquired in the Exchange are connected into a third-party crude oil pipeline gathering system, which will assure flow capacity for this production as well asany volumes from future wells on this acreage. With these acreage acquisitions, our total net acreage in the Midland Basin increased to approximately 29,500acres, of which approximately 22,800 acres are operated by us. For further discussion, see Note 3. Acquisitions and Divestitures in the Notes to ConsolidatedFinancial Statements included in this report. Upon finalization of documents for an agreed-upon mineral lease in Reagan County, which is expected to occurin the first quarter of 2019, we will have approximately 30,200 net acres in the core of the Midland Basin. Bold TransactionOn May 9, 2017, Earthstone completed a contribution agreement dated as of November 7, 2016 and as amended on March 21, 2017 (the “Bold ContributionAgreement”), by and among Earthstone, EEH, Lynden USA Inc., a Utah corporation ("Lynden US"), Lynden USA Operating, LLC, a Texas limited liabilitycompany (“Lynden Op”), Bold Energy Holdings, LLC, a Texas limited liability company (“Bold Holdings”), and Bold Energy III LLC, a Texas limitedliability company (“Bold”). The purpose of the Bold Contribution Agreement was to provide for, among other things described below, the businesscombination between Earthstone and Bold, which owned significant developed and undeveloped oil and natural gas properties in the Midland Basin ofTexas (the “Bold Transaction”).The Bold Transaction was structured in a manner commonly known as an “Up-C.” Under this structure and the Bold Contribution Agreement, (i) Earthstonerecapitalized its common stock into two classes - Class A common stock, $0.001 par value per share (the “Class A Common Stock”), and Class B commonstock, $0.001 par value per share (the “Class B Common Stock”), and all of Earthstone’s existing outstanding common stock, $0.001 par value per share (the“Common Stock”), was recapitalized on a9Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Each EEH Unit, together with one share of Class B Common Stock, areconvertible into one share of Class A Common Stock. Organizational StructureEarthstone is the sole managing member of EEH, with a controlling interest in EEH. Earthstone, together with its wholly-owned subsidiary, Lynden EnergyCorp., a corporation organized under the laws of British Columbia (“Lynden Corp”), and Lynden Corp’s wholly-owned consolidated subsidiary, Lynden USand also a member of EEH, consolidates the financial results of EEH and records a noncontrolling interest in the Consolidated Financial Statementsrepresenting the economic interests of EEH's members other than Earthstone and Lynden US. Our OperationsWe are currently the operator of properties containing approximately 82% of our proved oil and natural gas reserves and 86% of our proved PV-10 as ofDecember 31, 2018 (see reconciliation of PV-10 to the standardized measure of discounted future net cash flows in Item 2. Properties). As operator, wemanage and are able to directly influence development and production of operations of our operated properties. Independent contractors engaged by usprovide all the equipment and personnel associated with drilling and completion activities. We employ petroleum engineers, geologists and landprofessionals who work on improving operating cost, production rates and reserves. Our producing properties have reasonably predictable productionprofiles and cash flows, subject to commodity price 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.Operational RisksOil and natural gas exploitation, development and production involve a high degree of risk, which even a combination of experience, knowledge and carefulevaluation may not be able to overcome. There is no assurance that we will acquire, discover or produce additional oil and natural gas in commercialquantities. Oil and natural gas operations also involve the risk that well fires, blowouts, equipment failure, human error and other events may cause accidentalleakage or spills of toxic or hazardous materials, such as petroleum liquids or drilling fluids into the environment or cause significant injury to persons orproperty. In such event, substantial liabilities to third parties or governmental entities may be incurred, the satisfaction of which could substantially reduceour available cash and possibly result in loss of oil and natural gas properties. Such hazards may also cause damage to or destruction of wells, producingformations, 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 notavailable or because we believe the premium costs are prohibitive. A loss not fully covered by 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 CustomersWe market the majority of the production from properties we operate for both our account and the account of the other working interest owners in theseproperties. 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 yearended December 31, 2018, three purchasers accounted for 27%, 11% and 10%, respectively, of our revenue during the period. For the year endedDecember 31, 2017, three purchasers accounted for 18%, 14% and 14%, respectively, of our revenue during the period. No other customer accounted for morethan 10% of our revenue during these periods. If a major customer decided to stop purchasing oil and natural gas from us, revenue could decline and ouroperating 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 amaterially adverse effect on our financial condition or results of operations, as crude oil and natural gas are fungible products with well-established marketsand numerous purchasers.10Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results.TransportationDuring the planning stage of our prospective and productive units and acreage, we consider required flow-lines, gathering and delivery infrastructure. Our oilis 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 meterand pipeline interconnection point through our gathering systems.In addition, we generally move the majority of our produced salt water by pipeline connected to our operated salt water disposal wells or by pipeline tocommercial disposal facilities.CompetitionThe 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 gascompanies, drilling partnership programs, individual producers, natural gas marketers, and major pipeline companies, as well as participants in otherindustries supplying energy and fuel to consumers. Many of our competitors are large, well-established companies. They may be able to pay more for seismicinformation 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 orhuman resources permit. Our ability to acquire additional properties in the future, and our ability to fund the acquisition of such properties, will be dependentupon 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 besubstantially affected by various forms of energy legislation and/or regulation considered from time to time by the governments of the United States and thejurisdictions 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 effectsupon our future operations. Such laws and regulations may substantially increase the costs of exploring for, developing or producing oil and natural gas andmay prevent or delay the commencement or continuation of a given operation. Our larger competitors may be able to absorb the burden of existing and anychanges to, federal, state and local laws and regulations more easily than we can, which would adversely affect our competitive position.Segment Information and Geographic AreaOperating segments are defined under accounting principles generally accepted in the United States (“GAAP”) as components of an enterprise that (i) engagein activities from which it may earn revenues and incur expenses (ii) for which separate operational financial information is available and is regularlyevaluated 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 BusinessWeather conditions often affect the demand for, and prices of, natural gas and can also delay oil and natural gas drilling activities, disrupting our overallbusiness plans. Demand for natural gas is typically higher during the winter, resulting in higher natural gas prices for our natural gas production during ourfirst and fourth fiscal quarters. Due to these seasonal fluctuations, our results of operations for individual quarterly periods may not be indicative of the resultsthat we may realize on an annual basis.Markets for Sale of ProductionOur ability to market oil and natural gas found and produced, depends on numerous factors beyond our control, the effect of which cannot be accuratelypredicted or anticipated. Some of these factors include, without limitation, the availability of other domestic and foreign production, the marketing ofcompetitive fuels, the proximity and capacity of pipelines, fluctuations in supply and demand, the availability of a ready market, the effect of United Statesfederal and state regulation of production, refining, transportation and sales and general national and worldwide economic conditions. Additionally, we mayexperience delays in marketing natural gas production and fluctuations in natural gas prices and we may experience short-term delays in marketing oil due totrucking 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 ismarketed, 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 wereremoved in 1985 and the remainder were lifted by the Natural Gas Wellhead Decontrol Act of 1989. Thus, currently, the United States natural gas market isoperating in a free market environment in which the price of gas is determined11Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

At the same time, the domestic natural gas industry has also seen a dramatic change in the manner in which gas isbought, sold and transported. In most cases, natural gas is no longer sold to a pipeline company. Instead, the pipeline company now primarily serves the roleof 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. Specifically,increased foreign production and increased efficiencies in horizontal drilling, combined with exploration of newly developed 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 themany uncertainties affecting the supply and demand for oil, natural gas and NGLs, we are unable to accurately predict future oil, natural gas and NGLs pricesor 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 PropertiesWe 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 naturalgas 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 gasproperties. 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, farmoutagreements, 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 suppliersand contractors and contractual liens under operating agreements;•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 revenueinterests and in estimating the quantity and value of our reserves. We believe that the burdens and obligations affecting our oil and natural gas properties arecommon in our industry with respect to the types of properties we own.Operational RegulationsAll 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 oroperate 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 tovarious conservation laws and regulations. These laws and regulations govern the size of drilling and spacing units, the density of wells that may be drilled inoil 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 orintegration of land and leases to facilitate development, other states including Texas, where we operate, rely primarily or exclusively on voluntary pooling ofland 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 orflaring of natural gas, and impose specified requirements regarding the ratability of production. On some occasions, local authorities have imposed moratoriaor other restrictions on exploration, development and production activities pending investigations and studies addressing potential local impacts of theseactivities 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 thelocations at which we can drill, although we can apply for exceptions to such regulations or to have reductions in well spacing. Failure to comply withapplicable laws and regulations can result in substantial penalties. The regulatory burden on the industry increases the cost of doing business and affectsprofitability. Moreover, each state generally imposes a production or severance tax with respect to the production and sale of oil, natural gas and natural gasliquids within its jurisdiction.12Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

FERC regulates interstate naturalgas 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 ournatural gas.Intrastate natural gas transportation is also subject to regulation by state regulatory agencies. The basis for intrastate regulation of natural gas transportationand the degree of regulatory oversight and scrutiny given to intrastate natural gas pipeline rates and services varies from state to state. Insofar as suchregulation within a particular state will generally affect all intrastate natural gas shippers within the state on a comparable basis, we believe that theregulation of similarly situated intrastate natural gas transportation in any states in which we operate and ship natural gas on an intrastate basis will not affectour operations in any way that is of material difference from those of our competitors. Like the regulation of interstate transportation rates, the regulation ofintrastate 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 LiquidsThe 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 stateregulation. FERC, however, regulates interstate natural gas transportation rates, and terms and conditions of transportation service, which affects themarketing 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 andnatural gas liquids is affected by the cost of transporting those products to market. FERC regulates the transportation of oil and liquids on interstatepipelines under the provision of the Interstate Commerce Act, the Energy Policy Act of 1992 and regulations issued under those statutes. Intrastatetransportation of oil, natural gas liquids, and other products, is dependent on pipelines whose rates, terms and conditions of service are subject to regulationby state regulatory bodies under state statutes. In addition, while sales by producers of natural gas and all sales of crude oil, condensate, and natural gasliquids can currently be made at uncontrolled market prices, Congress could reenact price controls in the future. Changes in FERC or state policies and regulations or laws may adversely affect the availability and reliability of firm and/or interruptible transportationservice on interstate pipelines, and we cannot predict what future action that FERC or state regulatory bodies will take. We do not believe, however, that anyregulatory changes will affect us in a way that materially differs from the way they will affect other natural gas producers, gatherers and marketers with whichwe compete.Environmental RegulationsOur operations are also subject to stringent federal, state and local laws regulating the discharge of materials into the environment or otherwise relating tohealth 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 withenvironmental laws and regulations may result in the assessment of substantial administrative, civil and criminal penalties, as well as the issuance ofinjunctions limiting or prohibiting our activities. In addition, some laws and regulations relating to protection of the environment may, in certaincircumstances, impose strict liability for environmental contamination, which could result in liability for environmental damages and cleanup costs withoutregard 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 andproduction, air emissions, waste management, and underground injection of waste material. Environmental laws and regulations have been subject tofrequent changes over the years, and the imposition of more stringent requirements could have a material adverse effect on our financial condition and resultsof operations. The following is a summary of the more significant existing environmental, health and safety laws and regulations to which our businessoperations are subject and for which compliance in the future may have a material adverse impact on our capital expenditures, earnings and competitiveposition.Hazardous Substances and WastesThe federal Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (“CERCLA”), also known as the Superfund law, andcomparable state laws impose liability, without regard to fault or the legality of the original conduct on certain categories of persons that are considered to beresponsible for the release of a hazardous substance into the environment. These persons may include the current or former owner or operator of the site orsites where the release occurred and companies that disposed or arranged for the disposal of hazardous substances found at the site. Under CERCLA, thesepotentially responsible persons may be subject to strict, joint and several liability for the costs of investigating and cleaning up hazardous substances that13Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

In addition, it is not uncommon forneighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by hazardous substances or otherpollutants 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 environmentalregulations may, in certain circumstances, be attributed to us. We generate materials in the course of our operations that may be regulated as hazardoussubstances 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 theprovisions of RCRA, and some states have adopted their own, more stringent requirements. Drilling fluids, produced waters and most of the other wastesassociated with the exploration, development and production of oil and natural gas are currently regulated under RCRA’s solid (non-hazardous) wasteprovisions. However, legislation has been proposed from time to time and various environmental groups have filed lawsuits that, if successful, could result inthe reclassification of certain oil and natural gas exploration and production wastes as “hazardous wastes,” which would make such wastes subject to muchmore stringent handling, disposal and clean-up requirements. For example, in response to a lawsuit filed in the U.S. District Court for the District of Columbiaby several non-governmental environmental groups against the EPA for the agency’s failure to timely assess its RCRA Subtitle D criteria regulations for oiland natural gas wastes, the EPA and the environmental groups entered into an agreement that was finalized in a consent decree issued by the District Court onDecember 28, 2016. Under the decree, the EPA is required to propose no later than March 15, 2019, a rulemaking for revision of certain Subtitle D criteriaregulations pertaining to oil and natural gas wastes or sign a determination that revision of the regulations is not necessary. EPA action in response to theconsent decree remains pending. If the EPA proposes a rulemaking for revised oil and natural gas waste regulations, the consent decree requires that the EPAtake final action following notice and comment rulemaking no later than July 15, 2021. A loss of the RCRA exclusion for drilling fluids, produced watersand 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, whichcould 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 orwastes released thereon may be subject to CERCLA, RCRA and analogous state laws. Under these laws, we have been and may be required to remove orremediate such materials or wastes.Water DischargesThe federal Clean Water Act and analogous state laws impose restrictions and strict controls with respect to the discharge of pollutants, including spills andleaks of oil and other substances, into waters of the United States. The discharge of pollutants into regulated waters, including jurisdictional wetlands, isprohibited, 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. ArmyCorps of Engineers rule defining the scope of federal jurisdiction over Waters of the United States (the “WOTUS rule”) became effective; however, this rulehas been stayed nationwide by the U.S. Court of Appeals for the Sixth Circuit while the appellate court and numerous federal district courts consider lawsuitsopposing implementation of the rule. The U.S. Supreme Court considered the issue of which court has jurisdiction to hear challenges to the WOTUS rule, andin January 2018 concluded that jurisdiction rests with the federal district courts. In addition, in 2017, President Trump issued an executive order directing theEPA and the U.S. Army Corps of Engineers to review the WOTUS rule and, if the agencies’ reviews find that the rule does not meet the executive order’s goalof promoting economic growth while reducing regulatory uncertainty, to initiate a new rulemaking to repeal or revise the rule. Pursuant to the executiveorder, in June 2017, the EPA and U.S. Army Corps of Engineers formally proposed to rescind the WOTUS rule. In January 2018, the EPA and the U.S. ArmyCorps of Engineers finalized a rule that would delay applicability of the WOTUS rule for two years, but a federal judge barred the agencies’ suspension of therule in August 2018. Separately, a federal court in Georgia enjoined implementation of the rule in 11 states. However, in December 2018, the EPA and theU.S. Army Corps released a proposed rule that would replace the WOTUS rule and significantly reduce the waters subject to federal regulation under theCWA. Such proposal is currently subject to public review and comment, after which additional legal challenges are anticipated. The scope of thejurisdictional reach of the Clean Water Act will likely remain uncertain for several years.The process for obtaining permits has the potential to delay our operations. Spill prevention, control and countermeasure requirements of federal laws requireappropriate containment berms and similar structures to help prevent the contamination of navigable waters by a petroleum hydrocarbon tank spill, rupture orleak. In addition, the Clean Water Act and analogous state laws require individual permits or coverage under general permits for discharges of storm waterrunoff from certain types of facilities. Federal and state regulatory agencies can impose administrative, civil and criminal penalties as well as otherenforcement 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 OilPollution Act of 1990 (“OPA”), impose rigorous requirements for spill prevention14Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results.and response planning, as well as substantial potential liability for the costs of removal, remediation, and damages in connection with any unauthorizeddischarges.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 thedrilling 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 foradministering. In Texas, the Texas Railroad Commission (“RRC”) regulates the disposal of produced water by injection well. Permits must be obtainedbefore drilling salt water disposal wells, and casing integrity monitoring must be conducted periodically to ensure the casing is not leaking salt water togroundwater. Contamination of groundwater by oil and natural gas drilling, production, and related operations may result in fines, penalties, and remediationcosts, among other sanctions and liabilities under the SDWA and state laws. In response to recent seismic events near underground injection wells used forthe disposal of oil and natural gas-related waste waters, federal and some state agencies have begun investigating whether such wells have caused increasedseismic activity, and some states have shut down or placed volumetric injection limits on existing wells or imposed moratoria on the use of such injectionwells. In response to concerns related to induced seismicity, regulators in some states have already adopted or are considering additional requirements relatedto seismic safety. For example, the RRC has adopted rules for injection wells to address these seismic activity concerns in Texas. Among other things, therules require companies seeking permits for disposal wells to provide seismic activity data in permit applications, provide for more frequent monitoring andreporting 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 turnimpact the availability of injection wells for disposal of wastewater from our operations. Increased costs associated with the transportation and disposal ofproduced water, including the cost of complying with regulations concerning produced water disposal, may reduce our profitability. The costs associatedwith 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 amaterial adverse effect on our operations. In addition, third party claims may be filed by landowners and other parties claiming damages for alternative watersupplies, property damages, and bodily injury.Hydraulic FracturingOur completion operations are subject to regulation, which may increase in the short- or long-term. In particular, the well completion technique known ashydraulic fracturing is used to stimulate production of oil and natural gas has come under increased scrutiny by the environmental community, and manylocal, state and federal regulators. Hydraulic fracturing involves the injection of water, sand and additives under pressure, usually down casing that iscemented in the wellbore, into prospective rock formations at depths to stimulate oil and natural gas production. We engage third parties to providehydraulic 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 theUIC program, and the hydraulic fracturing process is typically regulated by state oil and gas commissions. However, legislation has been proposed in recentsessions of Congress to amend the SDWA to repeal the exemption for hydraulic fracturing from the definition of “underground injection,” to require federalpermitting and regulatory control of hydraulic fracturing, and to require disclosure of the chemical constituents of the fluids used in the fracturing process.Furthermore, several federal agencies have asserted regulatory authority over certain aspects of the fracturing process. For example, the EPA has taken theposition 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 gasextraction facilities to publicly owned wastewater treatment plants. The EPA is also conducting a study of private wastewater treatment facilities (also knownas centralized waste treatment (“CWT”) facilities) accepting oil and natural gas extraction wastewater. The EPA is collecting data and information related tothe extent to which CWT facilities accept such wastewater, available treatment technologies (and their associated costs), discharge characteristics, financialcharacteristics of CWT facilities, and the environmental impacts of discharges from CWT facilities.In addition, on March 26, 2015, the Bureau of Land Management (the “BLM”) published a final rule governing hydraulic fracturing on federal and Indianlands. Also, on November 15, 2016, the BLM finalized a waste preventing rule to reduce the flaring, venting and leaking of methane from oil and natural gasoperations on federal and Indian lands. On March 28, 2017, President Trump signed an executive order directing the BLM to review the above rules and, ifappropriate, to initiate a rulemaking to rescind or revise them. Accordingly, on December 29, 2017, the BLM published a final rule to rescind the 2015hydraulic fracturing rule; however, a coalition of environmentalists, tribal advocates and the state of California filed lawsuits challenging the rule rescission.Also, on February 22, 2018, the BLM published proposed amendments to the waste prevention rule that would eliminate certain air quality provisions and,on April 4, 2018, a federal district court stayed certain provisions of the 2016 rule. At this time, it is uncertain when, or if, the rules will be implemented, andwhat impact they would have on our operations.15Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results.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 releaseda report with findings and recommendations related to public concern about induced seismic activity from disposal wells. The report recommends strategiesfor managing and minimizing the potential for significant injection-induced seismic events. Other governmental agencies, including the U.S. Department ofEnergy, the U.S. Geological Survey, and the U.S. Government Accountability Office, have evaluated or are evaluating various other aspects of hydraulicfracturing. These ongoing or proposed studies could spur initiatives to further regulate hydraulic fracturing and could ultimately make it more difficult orcostly for us to perform fracturing and increase our costs of compliance and doing business.Some states and local jurisdictions in which we operate or hold oil and natural gas interests have adopted or are considering adopting regulations that couldrestrict or prohibit hydraulic fracturing in certain circumstances, impose more stringent operating standards and/or require the disclosure of the compositionof hydraulic fracturing fluids. If new or more stringent state or local legal restrictions relating to the hydraulic fracturing process are adopted in areas wherewe operate, we could incur potentially significant added costs to comply with such requirements, experience delays or curtailment in the pursuit ofexploration, 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 ondrinking water supplies, use of water and the potential for impacts to surface water, groundwater and the environment generally. A number of lawsuits andenforcement actions have been initiated across the country implicating hydraulic fracturing practices. If new laws or regulations that significantly restricthydraulic fracturing are adopted, such laws could make it more difficult or costly for us to perform fracturing to stimulate production from tight formations aswell as make it easier for third parties opposing the hydraulic fracturing process to initiate legal proceedings based on allegations that specific chemicalsused in the fracturing process could adversely affect groundwater. In addition, if hydraulic fracturing is further regulated at the federal, state or local level, ourfracturing 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 andpotential increases in costs. Such legislative changes could cause us to incur substantial compliance costs, and compliance or the consequences of any failureto 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 impacton our business of newly enacted or potential federal, state or local laws governing hydraulic fracturing.Air EmissionsThe federal Clean Air Act and comparable state laws restrict emissions of various air pollutants through permitting programs and the imposition of otherrequirements. In addition, the EPA has developed and continues to develop stringent regulations governing emissions of toxic air pollutants at specifiedsources, 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 Clean Air Act and associated state laws and regulations. Our operations, or the operations of servicecompanies engaged by us, may in certain circumstances and locations be subject to permits and restrictions under these statutes for emissions of airpollutants.In 2012 and 2016, the EPA issued New Source Performance Standards to regulate emissions of sources of volatile organic compounds (“VOCs”), sulfurdioxide, 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, andreconstructed equipment, processes, and activities across the oil and natural gas sector. However, in a March 28, 2017 executive order, President Trumpdirected 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 ofpromoting clean and safe development of the nation’s energy resources, while at the same time avoiding regulatory burdens that unnecessarily encumberenergy production. In June 2017, the EPA published a proposed rule to stay for two years certain requirements of the 2016 regulations, including fugitiveemission requirements. On September 11, 2018, the EPA proposed targeted improvements to the rule, including amendments to the rule’s fugitive emissionsmonitoring requirements, and expects to “significantly reduce” the regulatory burden of the rule in doing so. These standards, as well as any future laws andtheir implementing regulations, may require us to obtain pre-approval for the expansion or modification of existing facilities or the construction of newfacilities expected to produce air emissions, impose stringent air permit requirements, or mandate the use of specific equipment or technologies to controlemissions. 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 billionto 70 parts per billion. In July 2018, the EPA finished issuing area designations with respect to ground-level ozone for U.S. counties as either“attainment/unclassifiable” or “unclassifiable.” Reclassification of areas of state16Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely. The user assumes all risks for any damages or losses arising from any use of this information,except to the extent such damages or losses cannot be limited or excluded by applicable law. Past financial performance is no guarantee of future results.implementation of the revised NAAQS could result in stricter permitting requirements, delay or prohibit our ability to obtain such permits, and result inincreased expenditures for pollution control equipment, the costs of which could be significant.Climate ChangeIn response to findings that emissions of carbon dioxide, methane and other greenhouse gases (“GHGs”) endanger public health and the environment, theEPA has adopted regulations under existing provisions of the Clean Air Act that, among other things, establish Prevention of Significant Deterioration(“PSD”), construction and Title V operating permit reviews for certain large stationary sources. Facilities required to obtain PSD permits for their GHGemissions also will be required to meet “best available control technology” standards for these emissions. EPA rulemakings related to GHG emissions couldadversely affect our operations and restrict or delay our ability to obtain air permits for new or modified sources. In addition, the EPA has adopted rulesrequiring the annual reporting of GHG emissions from certain petroleum and natural gas system sources in the U.S., including, among others, onshore andoffshore production facilities, which include certain of our operations. Also, as noted above, the EPA has promulgated a New Source Performance Standardrelated to methane emissions from the oil and natural gas source category.While Congress has considered legislation related to the reduction of GHG emissions in the past, no significant legislation to reduce GHG emissions has beenadopted at the federal level. In the absence of Congressional action, a number of state and regional GHG restrictions have emerged. At the international level,the United States joined the international community at the 21st Conference of the Parties of the United Nations Framework Convention on Climate Changein Paris, France. The Paris Agreement entered into force in November 2016. Although this agreement does not create any binding obligations for nations tolimit their GHG emissions, it does include pledges from participating nations to voluntarily limit or reduce future emissions. In June 2017, President Trumpstated that the United States would withdraw from the Paris Agreement, but may enter into a future international agreement related to GHGs. The ParisAgreement provides for a four-year exit process beginning when it took effect in November 2016, which would result in an effective exit date of November2020. The United States’ adherence to the exit process is uncertain, and the terms on which the United States may reenter the Paris Agreement or a separatelynegotiated agreement are unclear at this time. Although it is not possible at this time to predict how legislation or new regulations that may be adopted toaddress GHG emissions would impact our business, any such future laws and regulations imposing reporting obligations on, or limiting emissions of GHGsfrom, our equipment and operations could require us to incur costs to reduce emissions of GHGs associated with our operations.Restrictions on emissions of methane or carbon dioxide that may be imposed could adversely impact the demand for, price of and value of our products andreserves. As our operations also emit greenhouse gases directly, current and future laws or regulations limiting such emissions could increase our own costs.Currently, our operations are not adversely impacted by existing federal, state and local climate change initiatives and, at this time, it is not possible toaccurately estimate how potential future laws or regulations addressing greenhouse gas emissions would impact our business. Notwithstanding potential risksrelated to climate change, the International Energy Agency estimates that global energy demand will continue to represent a major share of global energy usethrough 2040, and other private sector studies project continued growth in demand for the next two decades. However, recent activism directed at shiftingfunding away from companies with energy-related assets could result in limitations or restrictions on certain sources of funding for the energy sector. Finally,it should also be noted that many scientists have concluded that increasing concentrations of GHGs in the Earth’s atmosphere may produce climate changesthat have significant physical effects, such as increased frequency and severity of storms, floods, droughts and other climatic events; if any such effects wereto occur, they could have an adverse effect on our financial condition and results of operations.National Environmental Policy ActOil and natural gas exploration, development and production activities on federal lands are subject to the National Environmental Policy Act (“NEPA”).NEPA requires federal agencies, including the Department of the Interior, to evaluate major agency actions that have the potential to significantly impact theenvironment. The process involves the preparation of either an environmental assessment or environmental impact statement depending on whether thespecific circumstances surrounding the proposed federal action will have a significant impact on the human environment. The NEPA process involves publicinput through comments which can alter the nature of a proposed project either by limiting the scope of the project or requiring resource-specific mitigation.NEPA decisions can be appealed through the court system by process participants. This process may result in delaying the permitting and development ofprojects, increase the costs of permitting and developing some facilities and could result in certain instances in the cancellation of existing leases.Threatened and endangered species, migratory birds and natural resourcesVarious 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 and the Clean Water Act. The U.S. Fish andWildlife Service (“FWS”) may designate critical habitat areas that it believes are necessary for survival of threatened or endangered species. As a result of a2011 settlement agreement, the FWS was17Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results.required to make a determination on listing of more than 250 species as endangered or threatened under the FSA by no later than completion of the agency’s2017 fiscal year. The FWS missed the deadline but reportedly continues to review new species for protected status under the ESA pursuant to the settlementagreement. A critical habitat designation could result in further material restrictions on federal land use or on private land use and could delay or prohibitland access or development. Where takings of or harm to species or damages to wetlands, habitat, or natural resources occur or may occur, governmententities or at times private parties may act to prevent or restrict oil and natural gas exploration activities or seek damages for any injury, whether resultingfrom 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 Migratory Bird Treaty Act. Recently, there have been renewed calls to review protectionscurrently 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 Migratory Bird Treaty Act, and we are not aware of any proposed ESA listings that willmaterially affect our operations. The federal government in the past has issued indictments under the Migratory Bird Treaty Act to several oil and natural gascompanies after dead migratory birds were found near reserve pits associated with drilling activities. The identification or designation of previouslyunprotected species as threatened or endangered in areas where underlying property operations are conducted could cause us to incur increased costs arisingfrom species protection measures or could result in limitations on our development activities that could have an adverse impact on our ability to develop andproduce 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 thevalue of our leases.Hazard communications and community right to knowWe are subject to federal and state hazard communication and community right to know statutes and regulations. These regulations, including, but notlimited to, the federal Emergency Planning & Community Right-to-Know Act, govern record keeping and reporting of the use and release of hazardoussubstances and may require that information be provided to state and local government authorities, as well as the public.Occupational Safety and Health ActWe are subject to the requirements of the federal Occupational Safety and Health Act, as amended (“OSHA”), and comparable state statutes that regulate theprotection of the health and safety of workers. In addition, OSHA hazard communication standard requires that information be maintained about hazardousmaterials used or produced in operations and that this information be provided to employees, state and local government authorities and citizens.State RegulationTexas regulates the drilling for, and the production, gathering and sale of, oil and natural gas, including imposing severance taxes and requirements forobtaining drilling permits. Texas currently imposes a 4.6% severance tax on oil production and a 7.5% severance tax on natural gas production. States alsoregulate the method of developing new fields, the spacing and operation of wells and the prevention of waste of oil and natural gas resources. States mayregulate rates of production and may establish maximum daily production allowables from oil and natural gas wells based on market demand or resourceconservation, or both. States do not regulate wellhead prices or engage in other similar direct economic regulation, but we cannot assure our stockholders thatthey 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 tolimit 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 resourceconservation and equal employment opportunity. We do not believe that compliance with these laws will have a material adverse effect on us.Related InsuranceWe maintain insurance against some risks associated with above or underground contamination that may occur as a result of our exploration, developmentand 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 becommercially available or that this insurance will be available at premium levels that justify its purchase by us. The occurrence of a significant event that isnot 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 willcontinue. We did not have any material capital or other non-recurring expenditures in connection with complying with environmental laws or environmentalremediation matters in 2017, nor do we anticipate that such expenditures will be material in 2018.18Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Risk FactorsOur business is subject to various risks and uncertainties in the ordinary course of our business. The following summarizes significant risks and uncertaintiesthat may adversely affect our business, financial condition or results of operations. We cannot assure you that any of the events discussed in the risk factorsbelow 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 wecurrently deem immaterial may also materially affect our business. When considering an investment in our shares of Class A Common Stock, you shouldcarefully 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.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 capital expenditure obligations and financial commitments. Volatileand 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 rateof growth. These hydrocarbons are commodities, and therefore, their prices may be subject to wide fluctuations in response to relatively minor changes insupply 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, 2018, the West Texas Intermediate (“WTI”) spot price for oil declined from a high of $107.95 per Bbl in June 2014 to $26.19 perBbl in February 2016. 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 $1.49 per MMBtuin March 2016. During 2018, WTI spot prices ranged from $44.48 to $77.41 per Bbl and the Henry Hub spot price of natural gas rangedfrom $2.49 to $6.24 per MMBtu. Likewise, natural gas liquids, which are made up of ethane, propane, isobutane, normal butane and natural gasoline, each ofwhich have different uses and different pricing characteristics, have experienced significant declines in realized prices since the fall of 2014. The prices wereceive for oil, natural gas and natural gas liquids we produce and our production levels depend on numerous factors beyond our control, including:•worldwide and regional economic and financial conditions impacting global and regional 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 currentconflicts in the Middle East, as well as conditions in South America, Africa 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;•the price and availability of alternative fuels; and•domestic, local and foreign governmental regulation and taxes.21Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results.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 obtainneeded capital or financing on satisfactory terms, which could lead to a decline in our hydrocarbon reserves as existing reserves are depleted. A decrease inprices could render development projects and producing properties uneconomic, potentially resulting in a loss of mineral leases. Low commodity priceshave, at times, caused significant downward adjustments to our estimated proved reserves, and may cause us to make further downward adjustments in thefuture. Furthermore, our borrowing capacity could be significantly affected by decreased prices. Under the EEH Credit Agreement, our borrowing base issubject to semi-annual redeterminations (May 1 and November 1) and our lenders have the right to call for an interim determination of the borrowing baseunder certain circumstances. A sustained decline in oil, natural gas and natural gas liquids prices could adversely impact our borrowing base in futureborrowing base redeterminations, which could trigger repayment obligations under the EEH Credit Agreement to the extent our outstanding borrowingsexceed 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 themarket price of our shares.As a result of low prices for oil, natural gas and natural gas liquids, we have taken and may be required to take significant future write-downs of thefinancial 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 prevailingcommodity prices and specific market factors and circumstances at the time of prospective impairment reviews, and the continuing evaluation ofdevelopment plans, production data, economics and other factors, we have been required to, and may be required to significantly write-down the financialcarrying value of our oil and natural gas properties, which constitutes a non-cash charge to earnings. We may incur impairment charges in the future, whichcould have a material adverse effect on our results of operations for the periods in which such charges are recorded.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 gasreserves, 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, wewould record impairment charges to reduce the capitalized costs of such field to our estimate of the field’s fair market value. Unproved properties areevaluated at the lower of cost or fair market value. These types of charges will reduce our earnings and stockholders’ equity and could adversely affect ourstock price.We periodically assess our properties for impairment based on future estimates of proved and non-proved reserves, oil and natural gas prices, production ratesand operating, development and reclamation costs based on operating budget forecasts. Once incurred, an impairment charge cannot be reversed at a laterdate 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 incurimpairment 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. SeeNote 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 the EEH Credit Agreement as a result of a periodic borrowing base redetermination or otherwisemay negatively impact our liquidity and, consequently, our ability to fund our operations, including capital expenditures, and we may not have sufficientfunds to repay borrowings under the EEH Credit Agreement or any other obligation if required as a result of a borrowing base redetermination.Availability under the EEH Credit Agreement is currently subject to a borrowing base of $275.0 million. The borrowing base is subject to scheduledsemiannual redeterminations (May 1 and November 1), as well as other lender-elective borrowing base redeterminations. The lenders can unilaterally adjustthe borrowing base and the borrowings permitted to be outstanding under the EEH Credit Agreement. Reductions in estimates of our oil, natural gas andnatural gas liquids reserves may result in a reduction in our borrowing base under the EEH Credit Agreement (if prices are kept constant). Reductions in ourborrowing base under the EEH 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;22Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

We may make further borrowings under theEEH Credit Agreement in the future. Any significant reduction in our borrowing base under the EEH Credit Agreement as a result of borrowing baseredeterminations or otherwise will negatively impact our liquidity and our ability to fund our operations and, as a result, could have a material adverse effecton our financial position, results of operations and cash flows. Further, if the outstanding borrowings under the EEH Credit Agreement were to exceed theborrowing 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 ofoperations and/or cash flows.Producing oil and natural gas reservoirs are generally characterized by declining production rates that may vary depending upon reservoir characteristics andother 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 ornatural gas well are inherently imprecise and may be less precise with respect to new or emerging oil and natural gas formations with limited productionhistories than for more developed formations with established production histories. Our production levels and the reserves that we currently expect to recoverfrom our wells will change if production from our existing wells declines in a different manner than we have estimated and can change under othercircumstances. Thus, our estimated future oil and natural gas reserves and production and, therefore, our cash flows and results of operations are highlydependent upon our success in efficiently developing and exploiting our current properties and economically finding or acquiring additional recoverablereserves. We may not be able to develop, find or acquire additional reserves to replace our current and future production at acceptable costs. If we are unableto replace our current and future production, our cash flows and the value of our reserves may decrease, adversely affecting our business, financial conditionand results of operations.Estimates of proved oil and natural gas reserves involve assumptions and any material inaccuracies in these assumptions will materially affect thequantities 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 assumptionsrequired by SEC regulations relating to oil and natural gas prices, drilling and operating expenses, capital expenditures, taxes and availability of funds. Theprocess of estimating oil and natural gas reserves is complex and requires significant decisions, complex analyses and assumptions in evaluating availablegeological, 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 andnatural gas reserves will vary from those estimated. Any significant variance will likely materially affect the estimated quantities and the estimated value ofour 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 andnatural gas liquids prices in the markets for these commodities may shorten the economic lives of certain fields because it may become uneconomical toproduce 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 decreaseearnings or result in losses through higher depletion expense. These revisions, as well as revisions in the assumptions of future estimated cash flows of thosereserves, may also trigger impairment losses on certain properties, which may result in non-cash charges to earnings. See Note 7. Oil and Natural GasProperties 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 currentlyanticipate. Therefore, our estimated proved undeveloped reserves may not be ultimately developed or produced.At December 31, 2018, approximately 76% of our estimated reserves were classified as proved undeveloped. The development of ourestimated proved undeveloped reserves of 75,201 MBOE will require an estimated $963.1 million of development capital over the next five years.Development of these reserves may take longer and require higher levels of capital expenditures than we currently anticipate. The future development ofour proved undeveloped reserves is dependent on successful drilling and completion results, future commodity prices, costs and economic assumptions thatalign with our internal forecasts, as well as access to liquidity sources, such as the capital markets, the EEH Credit Agreement and derivative23Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Delays in the development of our reserves, increases in costs to drill and develop such reserves, or decreases in commodity prices will reduce thePV-10 value of our estimated proved undeveloped reserves and future net revenues estimated for such reserves and may result in some projects becominguneconomic. Moreover, under the SEC regulations, we may be required to write down our proved undeveloped reserves if we do not drill or have adevelopment plan to drill wells within a prescribed five-year period. The estimated reserve data assumes that we will make specified capital expenditures totimely develop our reserves. The estimates of these oil and natural gas reserves and the costs associated with development of these reserves have beenprepared in accordance with SEC regulations; however, actual capital expenditures may vary from estimated capital expenditures, development may notoccur as scheduled and actual results may not be as estimated.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 ourestimated 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 thecurrent market value of our estimated oil and natural gas reserves. In accordance with SEC requirements in effect at December 31, 2018 and 2017, we basedthe discounted future net cash flows from our proved reserves on the 12-month first-day-of-the-month oil and natural gas unweighted arithmetic averageprices 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 ofthe 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.The timing of both our production and incurring expenses related to developing and producing oil and natural gas properties will affect the timing andamount of actual future net revenues from proved reserves, and thus their actual present value. In addition, the 10% discount factor we use when calculatingstandardized measure may not be the most appropriate discount factor based on interest rates in effect from time to time and risks associated with our businessor 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 incometaxes will be dependent on our future taxable income. Actual future prices and costs may differ materially from those used in the estimates included in thisreport 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 inthe future. Development and exploratory drilling and production activities are subject to many risks, including the risk that no commercially productivereservoirs will be discovered. We acquire unproved properties and lease undeveloped acreage that we believe will enhance our growth potential and increaseour 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 wellsdrilled 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 propertiesthat 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 andoperating 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 maynot 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 assumethe 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 acquiredo not produce as projected or have liabilities we were unable to identify, we could experience a decline in our reserves and production, which couldadversely 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 theoccurrence or timing of their drilling and completion, which in certain instances could prevent production prior to the expiration date of mineral leasesfor such locations.24Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results.Although our management team has identified numerous potential drilling locations as a part of our long-range planning related to future drilling activitieson our existing acreage, our ability to drill and develop these locations depends on a number of factors, which are beyond our control, including, theavailability and cost of capital, oil, natural gas and natural gas liquids prices, drilling and production costs, the availability of drilling services andequipment, drilling results (including the impact of increased horizontal drilling density and longer laterals), lease expirations, gathering systems, marketingand pipeline transportation constraints, regulatory permits and approvals and other factors. In addition, we may alter the spacing between our anticipateddrilling 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 ultimatelyrecover. As such, our actual drilling and completion activities, may materially differ from those presently anticipated. Accordingly, it is uncertain to whatdegree 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 theseor any other potential drilling locations. Unless production is established, in accordance with the terms of mineral leases that are associated with theselocations, such leases could expire.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 andcompleted and the drilling rig is moved from the location, multi-well pad drilling delays the commencement of production from a given pad, which maycause 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 additional drilling rigs, equipment, supplies, personnel and oilfield services could adversely affect our ability to executeour 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 fieldoperations, geologists, geophysicists, engineers and other professionals in the oil and natural gas industry, can fluctuate significantly, often in correlationwith 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, ashave 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 equipmentcould be impacted if the United States imposes tariffs on imported goods from countries where these goods are produced. For example, the steel we use forpipes, valve fittings and other equipment is generally imported from other countries, and the price for steel has risen significantly in 2018 due at least in partto the 25% tariff imposed by United States on imported steel. We cannot predict whether these conditions will exist in the future and, if so, what their timingand duration will be. 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 financingon 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 anddevelopment of oil and natural gas reserves. We expect to fund our 2019 capital expenditures with cash on hand, cash generated by operations, borrowingsunder the EEH Credit Agreement and possibly through additional capital market transactions. The actual amount and timing of our future capitalexpenditures may differ materially from our estimates as a result of, among other things, oil and natural gas prices, actual drilling results, the availability ofhigh-quality drilling rigs and other services and equipment and regulatory, technological and competitive developments. A reduction in commodity pricesfrom 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 EEH Credit Agreement.If our revenues or the borrowing base under the EEH Credit Agreement decrease as a result of low oil and natural gas prices, operating difficulties, declines inreserves or for any other reason, we may have limited ability to obtain the capital necessary to sustain our operations and growth at current levels. Ifadditional 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 additionalfinancing could result in a curtailment of our operations25Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Recent equity returns in thesector versus other industry sectors have led to lower oil and gas representation in certain key equity market indices. Some investors, including certainpension funds, university endowments and family foundations, have stated policies to reduce or eliminate their investments in the oil and gas sector based onsocial and environment considerations. Certain other stakeholders have pressured commercial and investment banks to stop funding oil and gas projects.Such developments could result in downward pressure on the stock prices of oil and gas companies, including ours. This may also result in a reduction ofavailable capital funding for potential development projects, further impacting our future financial results.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 attractiveprices 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 intoderivative instrument contracts for a portion of our oil and natural gas production, including swaps, collars, puts and basis swaps. We recognize allderivatives as either assets or liabilities, measured at fair value, and recognize changes in the fair value of derivatives in current earnings. Accordingly, ourearnings may fluctuate significantly and our results of operations may be significantly and adversely affected because of changes in the fair market value ofour 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 ofOperations and Note 6. Derivative Financial Instruments in the Notes to Consolidated Financial Statements included in this report for additionalinformation.Derivatives reform legislation and related regulations could have an adverse effect on our ability to hedge risks associated with our business.The Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act") provides for federal oversight of the over-the-counter derivativesmarket and entities that participate in that market and mandates that the Commodity Futures Trading Commission (the "CFTC"), the SEC, and federalregulators of financial institutions adopt rules or regulations implementing the Dodd-Frank Act and providing definitions of terms used in the Dodd-FrankAct.The CFTC has finalized other regulations implementing the Dodd-Frank Act's provisions regarding trade reporting, margin, clearing, and trade execution;however, some regulations remain to be finalized and it is not possible at this time to predict when the CFTC will adopt final rules. For example, the CFTChas re-proposed regulations setting position limits for certain futures and option contracts in the major energy markets and for swaps that are their economicequivalents. Certain bona fide hedging transactions are expected to be made exempt from these limits. Also, it is possible that under recently adopted marginrules, some registered swap dealers may require us to post initial and variation margins in connection with certain swaps not subject to central clearing.The Dodd-Frank Act and any additional implementing regulations could significantly increase the cost of some commodity derivative contracts (includingthrough requirements to post collateral, which could adversely affect our available liquidity), materially alter the terms of some commodity derivativecontracts, limit our ability to trade some derivatives to hedge risks, reduce the availability of some derivatives to protect against risks we encounter, andreduce our ability to monetize or restructure our existing commodity derivative contracts. If we reduce our use of derivatives as a consequence, our results ofoperations may become more volatile and our cash flows may be less predictable, which could adversely affect our ability to plan for and fund capitalexpenditures. Increased volatility may make us less attractive to certain types of investors. Finally, the Dodd-Frank Act was intended, in part, to reduce thevolatility of oil and natural gas prices, which some legislators attributed to speculative trading26Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

If the implementing regulations result in lower commodity prices, our revenuescould be adversely affected. Any of these consequences could adversely affect our business, financial condition and results of operations.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. Wecompete with major integrated and larger independent oil and natural gas companies in seeking to acquire desirable oil and natural gas properties and leasesand for the equipment and services required to develop and operate properties. Many of our competitors have financial and other resources that aresubstantially greater than ours, which makes acquisitions of acreage or producing properties at economic prices difficult. Significant competition also existsin attracting and retaining technical personnel, including geologists, geophysicists, engineers, landmen and other specialists, as well as financial andadministrative 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 andnatural gas reserves. Without continued successful acquisition, of economic development projects, our current estimated oil and natural gas reserves willdecline due to continued production activities. Acquiring additional oil and natural gas properties, or businesses that own or operate such properties is animportant component of our business strategy. If we identify an appropriate acquisition candidate, management may be unable to negotiate mutuallyacceptable terms with the seller, finance the acquisition or obtain the necessary regulatory approvals. Our limited access to financial resources compared tolarger, better capitalized companies may limit our ability to make future acquisitions. If we are unable to complete suitable acquisitions, it may be moredifficult to replace and increase our reserves, and an inability to replace our reserves may have a material adverse effect on our financial condition and resultsof operations.Acquisitions involve a number of risks, including the risk that we will discover unanticipated liabilities or other problems associated with the acquiredbusiness or property.In assessing potential acquisitions, we consider information available in the public domain and information provided by the seller. In the event publiclyavailable 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 respectto drilling and completion costs and practices, geological, geophysical and petrophysical data, detailed production data on existing wells, and othertechnical and cost data not available in the public domain. Accordingly, the review and evaluation of businesses or properties to be acquired may notuncover 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, unexpectedenvironmental liabilities, title defects, unpaid royalties, taxes or other liabilities. If we acquire properties on an “as-is” basis, we may have limited or noremedies 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 theacquired properties, assumptions related to future oil and natural gas prices and operating costs, potential environmental and other liabilities and otherfactors. These assessments are often inexact and subjective. As a result, we may not recover the purchase price of a property from the sale of production fromthe 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 businessopportunities 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 drillingoperations.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;27Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely. The user assumes all risks for any damages or losses arising from any use of this information,except to the extent such damages or losses cannot be limited or excluded by applicable law. Past financial performance is no guarantee of future results.•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 forany 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 environmentalrisks 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 regulationsgoverning the discharge of materials into the environment as well as protection of the environment, operational safety, and related employee health andsafety 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 theassessment of administrative, civil, and criminal penalties; the imposition of investigatory and remedial liabilities; the issuance of injunctions that mayrestrict, 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 andother 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 thirdparties. Similarly, some environmental laws and regulations impose joint and several liability, meaning that we could be held responsible for more than ourshare of a particular reclamation or other obligation, and potentially the entire obligation, where other parties were involved in the activity giving rise to theliability. In addition, we may be required to make large and unanticipated capital expenditures to comply with applicable laws and regulations, for exampleby installing and maintaining pollution control devices. Similarly, our actual plugging and abandonment obligations may be more than our estimates. It isnot possible for us to estimate reliably the amount and timing of all future expenditures related to environmental matters, but we estimate that they will bematerial. 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 operatingrestrictions 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 theoperator. Federal, state and local governments have been adopting or considering restrictions on or prohibitions of fracturing in areas where we currentlyconduct operations, or in the future plan to conduct operations. Consequently, we could be subject to additional levels of regulation, operational delays orincreased operating costs and could have additional28Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely. The user assumes all risks for any damages or losses arising from any use of this information,except to the extent such damages or losses cannot be limited or excluded by applicable law. Past financial performance is no guarantee of future results.regulatory burdens imposed upon us that could make it more difficult to perform hydraulic fracturing and increase our costs of compliance and doingbusiness.From time to time, for example, legislation has been proposed in Congress to amend the SDWA to require federal permitting of hydraulic fracturing and thedisclosure of chemicals used in the hydraulic fracturing process. Further, the EPA completed a study finding that hydraulic fracturing could potentially harmdrinking 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. For example, onMarch 26, 2015, the BLM published a final rule governing hydraulic fracturing on federal and Indian lands. Also, on November 15, 2016, the BLM finalizeda waste preventing rule to reduce the flaring, venting and leaking of methane from oil and natural gas operations on federal and Indian lands. On March 28,2017, President Trump signed an executive order directing the BLM to review the above rules and, if appropriate, to initiate a rulemaking to rescind or revisethem. Accordingly, on December 29, 2017, the BLM published a final rule to rescind the 2015 hydraulic fracturing rule; however, a coalition ofenvironmentalists, tribal advocates and the state of California filed lawsuits challenging the rule rescission. Also, on February 22, 2018, the BLM publishedproposed amendments to the waste prevention rule that would eliminate certain air quality provisions and, on April 4, 2018, a federal district court stayedcertain provisions of the 2016 rule. 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 ofthe chemical constituents of the fluids used in the fracturing process, have been proposed in recent sessions of Congress. Several states and local jurisdictionsin 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 causedincreased seismic activity in certain areas. For example, in December 2016, the EPA released its final report regarding the potential impacts of hydraulicfracturing on drinking water resources, concluding that “water cycle” activities associated with hydraulic fracturing may impact drinking water resourcesunder certain circumstances such as water withdrawals for fracturing in times or areas of low water availability, surface spills during the management offracturing fluids, chemicals or produced water, injection of fracturing fluids into wells with inadequate mechanical integrity, injection of fracturing fluidsdirectly into groundwater resources, discharge of inadequately treated fracturing wastewater to surface waters, and disposal or storage of fracturing wastewaterin unlined pits. The results of these studies could lead federal and state governments and agencies to develop and implement additional regulations. Inaddition, on June 28, 2016, the EPA published a final rule prohibiting the discharge of wastewater from onshore unconventional oil and natural gasextraction facilities to publicly owned wastewater treatment plants. The EPA is also conducting a study of private wastewater treatment facilities (also knownas centralized waste treatment (“CWT”) facilities) accepting oil and natural gas extraction wastewater. The EPA is collecting data and information related tothe extent to which CWT facilities accept such wastewater, available treatment technologies (and their associated costs), discharge characteristics, financialcharacteristics 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 withoutthe 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 and production activities in the areas where we operate.Our exploration, exploitation and development activities and equipment could be adversely affected by extreme weather conditions, such as hurricanes,which may cause a loss of production from temporary cessation of activity or lost or damaged facilities and equipment. Such extreme weather conditionscould 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 highcosts could delay or temporarily halt our operations and materially increase our operation and capital costs, which could have a material adverse effect on ourbusiness, financial condition and results of operations.Climate change legislation or regulations restricting emissions of "greenhouse gases" could result in increased operating costs and reduced demand forthe oil, natural gas and natural gas liquids we produce.In response to findings that emissions of carbon dioxide, methane and other GHGs present a danger to public health and the environment, the EPA hasadopted regulations under existing provisions of the Clean Air Act that, among other things, establish PSD, construction and Title V operating permit reviewsfor certain large stationary sources. Facilities required to obtain PSD permits for their GHG emissions also will be required to meet “best available controltechnology” standards for these emissions.29Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results.EPA rulemakings related to GHG emissions could adversely affect our operations and restrict or delay our ability to obtain air permits for new or modifiedsources. In addition, the EPA has adopted rules requiring the annual reporting of GHG emissions from certain petroleum and natural gas system sources in theU.S., including, among others, onshore and offshore production facilities, which include certain of our operations.Furthermore, in June 2016, the EPA finalized rules, known as Subpart OOOOa, that establish new controls for emissions of methane from new, modified orreconstructed sources in the oil and natural gas source category, including production, processing, transmission and storage activities. Following the changein presidential administration, there have been attempts to modify these regulations, and litigation concerning the regulations is ongoing. As a result, wecannot predict the scope of any final methane regulatory requirements or the cost to comply with such requirements. However, given the long-term trendtoward increasing regulation, future federal methane regulation of the oil and gas industry remains a possibility, and several states have separately imposedtheir own regulations on methane emissions from oil and gas production activities.While Congress has from time to time considered legislation to reduce emissions of GHGs, no significant legislation to reduce GHG emissions has beenadopted at the federal level. In the absence of Congressional action, a number of state and regional GHG restrictions have emerged. The adoption oflegislation or regulatory programs to reduce emissions of GHGs could require us to incur increased operating costs, such as costs to purchase and operateemissions control systems, to acquire emissions allowances or to comply with new regulatory or reporting requirements. Any such legislation or regulatoryprograms could also increase the cost of consuming, and thereby reduce demand for, the oil and gas we produce. Consequently, legislation and regulationprograms to reduce emissions of GHGs could have an adverse effect on our business, financial condition and results of operations. Reduced demand for theoil and gas we produce could also have the effect of lowering the value of our reserves.Demand for our products may also be adversely affected by conservation plans and efforts undertaken in response to global climate change, including plansdeveloped in connection with the recent Paris climate conference agreement reached in December 2015, which entered into force in November 2016.However, in August 2017, the U.S. State Department officially informed the United Nations of the intent of the United States to withdraw from the ParisClimate Agreement. The United States’ adherence to the exit process is uncertain and/or the terms on which the United States may reenter the ParisAgreement or a separately negotiated agreement are unclear at this time. Notwithstanding potential risks related to climate change, the International EnergyAgency estimates that global energy demand will continue to represent a major share of global energy use through 2040, and other private sector studiesproject continued growth in demand for the next two decades. However, recent activism directed at shifting funding away from companies with energy-related assets could result in limitations or restrictions on certain sources of funding for the energy sector. It should also be noted that many scientists haveconcluded that increasing concentrations of GHGs in the Earth’s atmosphere may produce climate changes that have significant physical effects, such asincreased frequency and severity of storms, floods, droughts and other climatic events. If any such effects were to occur, they could have an adverse effect onour financial condition and results of operations. Finally, increasing attention to the risks of climate change has resulted in an increased possibility oflawsuits brought by public and private entities against oil and gas companies in connection with their GHG emissions. Should we be targeted by any suchlitigation, we may incur liability, which, to the extent that societal pressures or political or other factors are involved, could be imposed without regard tocausation or contribution to the asserted damage, or to other mitigating factors.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 amaterial 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 processingcapacity. 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 theprices 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 inthe 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 productionremains at current levels or continues to increase, demand for our light crude oil production could result in widening price discounts to the world crude pricesand 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.We may incur more taxes and certain of our projects may become uneconomic if certain federal income tax deductions currently available with respect tooil and natural gas exploration and development are eliminated as a result of future legislation.In past years, legislation has been proposed that would, if enacted into law, make significant changes to U.S. tax laws, including to certain key U.S. federalincome tax provisions currently available to oil and natural gas exploration, development and production companies. Such legislative changes haveincluded, but not limited to, (i) the repeal of the percentage depletion allowance for oil and natural gas properties, (ii) the elimination of current deductionsfor intangible drilling and development costs, (iii) the elimination of the deduction for certain domestic production activities, and (iv) an extension of theamortization period for certain geological and geophysical expenditures. The Tax Cuts and Jobs Act of 2017 (the “TCJA”) did not directly affect deductionscurrently available to the oil and natural gas industry but any future changes in U.S. federal income tax laws could eliminate or30Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

New legislation and regulatory initiatives or restrictions relatingto 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 conditionand results of operations. Wastewaters from our operations typically are disposed of via underground injection. Some studies have linked earthquakes incertain areas to underground injection, which is leading to greater public scrutiny of disposal wells. Any new environmental initiatives or regulations thatrestrict injection of fluids, including, but not limited to, produced water, drilling fluids and other wastes associated with the exploration, development orproduction 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, couldincrease our operating costs and cause delays, interruptions or cessation of our operations, the extent of which cannot be predicted, and all of which wouldhave 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 currentlaws and regulations governing operations and activities of oil and natural gas exploration and development operations could have a material adverse impacton our business. In addition, there can be no assurance that income tax laws, royalty regulations and government programs related to our oil and natural gasproperties 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 noassurance that the various government permits, leases, licenses and approvals sought will be granted in respect of our activities or, if granted, will not becancelled or will be renewed upon expiration. There is no assurance that such permits, leases, licenses, and approvals will not contain terms and provisionswhich 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 gatheringsystems, transportation and processing facilities owned by third parties. In general, we will not control these facilities, and our access to them may be limitedor denied due to circumstances beyond our control. A significant disruption in the availability of these facilities could adversely impact our ability to deliverto market the hydrocarbons we produce and thereby cause a significant interruption in our operations. In some cases, our ability to deliver to market ourhydrocarbons is dependent upon coordination among third parties that own transportation and processing facilities we use, and any inability orunwillingness of those parties to coordinate efficiently could also interrupt our operations. The lack of availability or the lack of capacity on these systemsand facilities could result in the curtailment of production or the delay or discontinuance of drilling plans. This is more likely in areas with recent increasedproduction, such as our Permian Basin area where we have significant development activities. These are risks for which we generally will not maintaininsurance.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 partiesown the remaining portion of the working interest. Financial risks are inherent in any operation where the cost of drilling, equipping, completing andoperating wells is shared by more than one person. We could be held liable for joint activity obligations of other working interest owners, such asnonpayment of costs and liabilities arising from the actions of other working interest owners. In addition, declines in oil, natural gas and natural gas liquidsprices may increase the likelihood that some of these working interest owners, particularly those that are smaller and less established, are not able to fulfilltheir 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. Inthe event any of our project partners do not pay their share of such costs, we would likely have to pay those31Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Any temporary or sustained inability to service or repaysuch 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 abilityto respond to adverse economic changes in oil and natural gas markets and the economy in general.Non-operated properties are controlled by third parties that may not allow us to proceed with our planned capital expenditures. Activities on our operatedproperties could also be limited or subject to penalties.We currently are not the operator of some of our existing properties and, therefore, may not be able to influence production operations or further developmentactivities. Joint ownership is customary in the oil and natural gas industry and is generally conducted under the terms of a joint operating agreement (“JOA”),where one of the working interest owners is designated as the “operator” of the property. For non-operated properties, subject to the specific terms andconditions of the applicable JOA, if we disagree with the decision of a majority of working interest owners, we may be required, among other things, topostpone proposed activity or decline to participate in drilling and completing of wells. If we decline to participate, we might be forced to relinquish ourinterest through “in-or-out” elections or may be subject to certain non-consent penalties, as provided in a JOA. In-or-out elections may require a joint ownerto participate or forever relinquish its position, typically only in specific wells or drilling units, although such relinquished positions could be of a largerscope. Non-consent penalties typically allow participating working interest owners to recover from the proceeds of production, if any, an amount equal to200% to 500% of the non-participating working interest owner’s share of the cost of such operations. Further, even for properties operated by us, there may beinstances where decisions related to drilling, completion and operating cannot be made in our sole discretion. In such instances, we could be limited in ourdevelopment operations and subject to penalties as specified above if we choose not to participate in operations proposed by a majority of working interestowners.Because we cannot control activities on properties we do not operate, we cannot directly control the timing of exploration and development projects. If weare 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 workinginterest owners for these projects and our limited ability to influence operations and associated costs could prevent the realization of our targeted returns oncapital with respect to acquisition, exploration or development activities. The success and timing of exploration, acquisition and development activities onproperties 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 capitalexpenditures associated with the project. If we are not willing or able to fund required capital expenditures relating to a project when required by the majorityowner(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 asother 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. For example, software programs are used to interpret seismic data, manage drilling rigs, production equipment andgathering and transportation systems, as well as conduct reservoir modeling and reserve estimation for compliance reporting.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 gasreserves as well as other activities related to our business. Our business partners, including vendors, service providers, purchasers of our production andfinancial institutions are also dependent on digital technology.

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 couldresult in the unauthorized release, gathering, monitoring, misuse, loss or destruction of proprietary and other information, or other disruption of our businessoperations. In addition, certain cyber incidents, such as surveillance, may remain undetected for an extended period of time. In particular, our implementationof various procedures and controls to monitor and mitigate security threats and to increase security for our information, data, facilities and infrastructure mayresult in increased capital and operating costs. Costs for insurance may also increase as a result of security threats, and some insurance coverage may becomemore difficult to obtain, if available at all. Moreover, there can be no assurance that such procedures and controls will be sufficient to prevent securitybreaches from occurring. As cyber threats continue to evolve, we may be required to expend significant additional resources to continue to modify orenhance our protective measures or to investigate and remediate any information security vulnerabilities. A cyber incident involving our information systemsand related infrastructure, or that of our business partners, could disrupt our business plans and negatively impact our operations.We are subject to litigation relating to Bold and the Bold Transaction, and we may be subject to additional litigation, any of which could adversely affectour business, financial condition and operating results.Olenik v. Lodzinksi et al.: On June 2, 2017, Nicholas Olenik filed a purported shareholder class and derivative action in the Delaware Court of Chanceryagainst Earthstone’s Chief Executive Officer, along with other members of the Board, EnCap, Bold, Bold Holdings and OVR. The complaint alleges thatEarthstone’s directors breached their fiduciary duties in connection with the Bold Contribution Agreement. The Plaintiff asserts that the directors negotiatedthe Bold Transaction to benefit EnCap and its affiliates, failed to obtain adequate consideration for the Earthstone shareholders who were not affiliated withEnCap or Earthstone management, did not follow an adequate process in negotiating and approving the Bold Transaction and made materially misleading orincomplete proxy disclosures in connection with the Bold Transaction. The suit seeks unspecified damages and purports to assert claims derivatively onbehalf 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 withprejudice. The Plaintiff filed an appeal with the Delaware Supreme Court. Earthstone and each of the other defendants believe the claims are entirely withoutmerit and they intend to mount a vigorous defense. The ultimate outcome of this suit is uncertain, and while Earthstone is confident in its position, anypotential monetary recovery or loss to Earthstone cannot be estimated at this time.Hurricanes, earthquakes and other natural disasters could have an adverse effect on our business, financial condition and results of operations.Some of our properties are located in areas that are susceptible to hurricanes, earthquakes and other natural disasters. These natural disasters could potentiallydamage our assets and disrupt our production of oil and natural gas. In the third quarter of 2017, Hurricane Harvey caused disruptions in our operations and,as of December 31, 2017, we had incurred $0.2 million in losses. For more information regarding the impact of Hurricane Harvey on operating results, seeItem 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Natural disasters can similarly affect our facilities as well.In either case, losses could exceed our insurance coverage and our business, financial condition and results of operations could be adversely affected, perhapsmaterially.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 ourexecutive officers or other key employees could have a material adverse effect on our business.Risks Related to the Ownership of our Class A Common StockWe 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 upondistributions from EEH to cover our corporate and other overhead expenses and pay taxes.Upon the closing of the Contribution Agreement on May 9, 2017, we became a holding company and the sole manager of EEH and have no material assetsother than our equity interest in EEH. We have no independent means of generating revenue. We expect EEH to reimburse us for our corporate and otheroverhead expenses, and to the extent EEH has available cash, we intend to cause EEH to make distributions to the holders of EEH Units, including us, in anamount sufficient to cover all applicable U.S.33Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

We will likely belimited, however, in our ability to cause EEH and its subsidiaries to make these and other distributions due to the restrictions under an agreement providingfor our senior secured revolving credit facility (the “EEH Credit Agreement”). To the extent that we need funds, and EEH or its subsidiaries are restricted frommaking such distributions under applicable law or regulation or under the terms of their financing arrangements, or are otherwise unable to provide suchfunds, it could materially adversely affect our liquidity and financial condition.We are a “controlled company” within the meaning of the NYSE rules and, as a result, qualify for and rely on exemptions from certain corporategovernance requirements.EnCap controls a majority of the combined voting power of all classes of our outstanding voting stock. As a result, we are a controlled company within themeaning of the NYSE corporate governance standards. Under the NYSE rules, a company of which more than 50% of the voting power is held by anotherperson or group of persons acting together is a controlled company and may elect not to comply with certain NYSE corporate governance requirements,including the requirements that:•a majority of the board of directors consist of independent directors;•the nominating and governance committee be composed entirely of independent directors with a written charter addressing the committee’spurpose and responsibilities; and•the compensation committee be composed entirely of independent directors with a written charter addressing the committee’s purpose andresponsibilities.These requirements will not apply to us as long as we remain a controlled company. Accordingly, you may not have the same protections afforded tostockholders of companies that are subject to all of the corporate governance requirements of the NYSE.Our principal stockholders hold a substantial majority of the voting power of our Class A Common Stock and Class B Common Stock.Holders of Class A Common Stock and Class B Common Stock will vote together as a single class on all matters presented to our stockholders for their voteor approval, except as otherwise required by applicable law or our Third Amended and Restated Certificate of Incorporation. EnCap may be deemed tobeneficially own approximately 61.1% of our voting interests. As a significant stockholder, EnCap and certain of its affiliates could limit the ability of ourother stockholders to approve transactions they may deem to be in the best interests of our Company or delaying or preventing changes in control or changesin 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 toexercise significant influence over management and all matters requiring stockholder approval, regardless of whether or not other stockholders believe that apotential 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 interestsof our stockholders. In addition, EnCap and its affiliates may, from time to time, acquire interests in businesses that directly or indirectly compete with ourbusiness, as well as businesses that are significant existing or potential acquisition candidates or industry partners. EnCap and its affiliates may acquire orseek 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 topursue. Moreover, this concentration of stock ownership may also adversely affect the trading price of our Class A Common Stock to the extent investorsperceive a disadvantage in owning stock of a company with a controlling stockholder.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 anyadditional 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. Wecannot 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 futureissuances 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 ourClass A Common Stock (including shares issued in connection with an acquisition), or the perception that such sales could occur, may adversely affectprevailing market prices of our Class A Common Stock.Bold Holdings and its permitted transferees have the right to exchange their EEH Units and shares of Class B Common Stock for our Class A CommonStock pursuant to the terms of the EEH LLC Agreement.As of March 1, 2019, there were approximately 35.5 million shares of our Class A Common Stock that are issuable upon redemption or exchange of EEHUnits and shares of Class B Common Stock that are held by Bold Holdings or its permitted transferees. Pursuant to the EEH LLC Agreement, subject tocertain restrictions therein, holders of EEH Units and our Class B Common Stock are entitled to exchange such EEH Units and shares of Class B CommonStock for shares of our Class A Common Stock at any time.

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. Our future dividend policy is within the discretion of our Board and will depend upon various factors, including ourbusiness, financial condition, results of operations, capital requirements, and investment opportunities. In addition, the EEH Credit Agreement does not allowEEH to 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 CommonStock.Our Board of Directors can, without stockholder approval, cause preferred stock to be issued on terms that could adversely affect our commonstockholders.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 preferredstock, 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 theholders of our Class A Common Stock and Class B Common Stock would likely be subordinate to those of preferred holders and therefore could be adverselyaffected. The Board’s ability to determine the terms of preferred stock and to cause its issuance, while providing desirable flexibility in connection withpossible acquisitions and other corporate purposes, could have the effect of making it more difficult for a third party to acquire a majority of our outstandingvoting 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 shiftthe ability to control Earthstone to the holders of the preferred stock. Preferred stock could also have conversion rights into shares of Class A Common Stockat 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 receivethe net assets of Earthstone distributed in liquidation before the Class A common stockholders receive any distribution of the liquidated assets. We have nocurrent 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. Forinstance, if our financial results are below the expectations of securities analysts and investors, the market price of our Class A Common Stock coulddecrease, perhaps significantly. Other factors that may affect the market price of our Class A Common Stock include:•changes in oil and natural gas prices;•actual or anticipated fluctuations in our quarterly results of operations;•our liquidity;•sales of Class A Common Stock by our stockholders;•changes in our cash flow from operations or earnings estimates;•publication of research reports about us or the oil and natural gas exploration and production industry generally;•competition for, among other things, capital, acquisition of reserves, undeveloped land, and skilled personnel;•increases in market interest rates that may increase our cost of capital;•changes in applicable laws or regulations, court rulings, and enforcement and legal actions;•changes in market valuations of similar companies;•adverse market reaction to any indebtedness we may incur in the future;•additions or departures of key management personnel;•actions by our stockholders;•commencement of or involvement in litigation;•news reports relating to trends, concerns, technological or competitive developments, regulatory changes, and other related issues in ourindustry;35Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

These fluctuations often have been unrelated to the operatingperformance of companies in these markets. Market fluctuations and broad market, economic, and industry factors may negatively affect the price of ourClass A Common Stock, regardless of our operating performance. Any volatility or a significant decrease in the market price of our Class A Common Stockcould also negatively affect our ability to make acquisitions using Class A Common Stock. Further, if we were to be the object of securities class actionlitigation as a result of volatility in our Class A Common Stock price or for other reasons, it could result in substantial costs and diversion of ourmanagement’s attention and resources, which could negatively affect our financial results.We are subject to certain requirements of Section 404 of the Sarbanes-Oxley Act. If we fail to comply with the requirements of Section 404 or if we or ourauditors identify and report material weaknesses in internal control over financial reporting, our investors may lose confidence in our reportedinformation and our stock price may be negatively affected.As of December 31, 2018, we are required to comply with certain provisions of Section 404 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”).Section 404 requires that we document and test our internal control over financial reporting and issue our management’s assessment of our internal controlover financial reporting. This section also requires that our independent registered public accounting firm issue an attestation report on such internal control.If we fail to comply with the requirements of Section 404 of the Sarbanes-Oxley Act, or if we or our auditors identify and report material weaknesses in ourinternal control over financial reporting, the accuracy and timeliness of the filing of our annual and quarterly reports may be materially adversely affectedand could cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our Class ACommon Stock. In addition, a material weakness in the effectiveness of our internal control over financial reporting could result in an increased chance offraud and the loss of customers, reduce our ability to obtain financing and require additional expenditures to comply with these requirements, each of whichcould have a material adverse effect on our business, results of operations and financial condition.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 ofour 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, orany 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 avote, 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 votesthat 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 ofthis type can be effected without the participation or input of minority stockholders.Item 1B. Unresolved Staff CommentsNone.Item 2. PropertiesSummary of Oil and Gas PropertiesMidland BasinWe have an operated position of approximately 22,800 net acres in the core of the Midland Basin of west Texas across Reagan, Upton, and Midland countieswith an average working interest of approximately 94%. As of December 31, 2018, we had 15 gross vertical and 51 gross horizontal operated producingwells. Current internal estimates indicate 500 potential gross, largely de-risked, operated drilling locations, the vast majority of which are in various benchesof the Wolfcamp and the Spraberry formations. Of these 500 operated locations, 462 locations are expected to have an average working interest of 83%,whereas 38 locations are expected to be operated units where we hold an average working interest of approximately 35%. We are actively pursuing trades36Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

As of December 31, 2018, we had an interest in 100 gross vertical and 26 gross horizontal non-operated producing wells with anaverage working interest of approximately 36%.We have identified 366 potential gross horizontal non-operated drilling locations in various benches of the Wolfcamp and Spraberry formations with anestimated average working interest of approximately 25%.Eagle Ford TrendAs of December 31, 2018, we held approximately 29,000 gross (14,100 net) operated leasehold acres in Fayette, Gonzales and Karnes counties, Texas. Theacreage 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 EagleFord formations. We serve as the operator with working interests ranging from approximately 17% to 67%.As of December 31, 2018, we operated 93 gross Eagle Ford wells and 13 gross Austin Chalk wells and had non-operated interests in approximately five grossproducing Eagle Ford wells and one gross producing Austin Chalk well. We have identified a total of 68 potential gross Eagle Ford drilling locations in thisacreage. In addition, because our acreage position is prospective for the Austin Chalk and Upper Eagle Ford formations, we may have additional futureeconomic locations. The majority of our acreage is covered by an approximately 173 square mile 3-D seismic survey.Oil and Natural Gas ReservesAs of December 31, 2018, all of our oil and natural gas reserves were located in the state of Texas. We expect to further develop these properties throughadditional drilling and completion operations. Our reserve estimates have been prepared by Cawley, Gillespie & Associates, Inc. (“CG&A”), an independentpetroleum 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 furtherinformation 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 toConsolidated Financial Statements of this report.As of December 31, 2018, our estimated proved reserves totaled 98,847 MBOE and had a PV-10 value of approximately $1,008.5 million (see Non-GAAPReconciliation below) and a Standardized Measure of Discounted Future Net Cash Flows of approximately $959.5 million, all of which relate to ourproperties in Texas. We incurred approximately $153.2 million in capital expenditures, primarily drilling and completion costs, during 2018. We expect tofurther develop our properties through additional drilling.2018 Activity in Proved ReservesFrom January 1, 2018 to December 31, 2018, our total estimated proved reserves increased 24% from 79,976 MBOE to 98,847 MBOE. Of that, estimatedproved developed reserves increased 18% from 19,961 MBOE to 23,646 MBOE and estimated proved undeveloped reserves increased 25% from 60,015MBOE to 75,201 MBOE. These increases are primarily attributable to our successful drilling efforts in the Midland Basin, acquisitions and trades during theyear, as well as improved commodity prices.Proved Reserves as of December 31, 2018The below table sets forth a summary of our estimated crude oil, natural gas and natural gas liquids reserves as of December 31, 2018, based on the annualreserve estimate prepared by CG&A. In preparing this reserve report, CG&A evaluated 100% of our properties at December 31, 2018. Proved reserves areestimated based on the unweighted arithmetic average of the first-day-of-the-month price for each month within the 12-month period for the year. All pricesand costs associated with operating wells were held constant in accordance with the SEC guidelines. Our proved reserve categories as of December 31, 2018 are summarized in the table below:37Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Management believes that the presentation of the PV-10 value of its oil and natural gas properties isrelevant and useful to investors because it presents the estimated discounted future net cash flows attributable to our estimated proved reserves independentof 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-taxmeasure provides greater comparability of assets when evaluating companies because the timing and quantification of future income taxes is dependent oncompany-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 underGAAP, 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):Present value of estimated future net revenues (PV-10) (1)$1,008,500Future income taxes, discounted at 10%(49,048)Standardized measure of discounted future net cash flows (2)$959,452(1)Includes $557.4 million attributable to noncontrolling interests.(2)Includes $530.2 million attributable to noncontrolling interests.Drilled But Uncompleted WellsIn order to achieve efficiencies from a pricing and logistics standpoint, our customary sequence of drilling and completion operations is to drill a group ofwells and defer completion operations until all drilling operations for the group are concluded and then commence completion activities.

In 2018, total purchases of minerals in place of 6.8 MMBOE were primarily attributable to developed non-producing wells and undeveloped acreage acquired in the Midland Basin as part of an acreage trade, as further described in Note 3.Acquisitions and Divestitures in the Notes to Consolidated Financial Statements. •Revision to previous estimates. In 2018, the upward revisions of prior reserves of 6.1 MMBOE consisted of improved PUD reserves of 5.8MMBOE with improved proved developed reserves of 0.3 MMBOE. PUD revisions are a result of our successful drilling efforts in theMidland Basin as well as improved commodity prices.Notable changes in proved reserves for the year ended December 31, 2017 included the following:•Extensions and discoveries. In 2017, total extensions and discoveries of 30,763 MBOE was a result of successful drilling results and wellperformance primarily related to the Midland Basin. The closing of the Bold Transaction in May 2017 which included primarily operatedacreage in the Midland Basin was a significant contributor to this.•Sales of minerals in place. Sales of minerals in place totaled 2,976 MBOE during 2017 and were primarily related to the disposition of theBakken properties, as further described in Note 3. Acquisitions and Divestitures in the Notes to Consolidated Financial Statements.•Purchases of minerals in place. In 2017, total purchases of minerals in place of 45,911 MBOE were primarily attributable to the BoldTransaction, whereby we acquired interests in 63 producing oil and natural gas wells, developed non-producing wells and undevelopedacreage in the Midland Basin, as further described in Note 3. Acquisitions and Divestitures in the Notes to Consolidated FinancialStatements. •Revision to previous estimates. In 2017, the downward revisions of prior reserves of 2,901 MBOE consisted of negative revisions to PUDreserves of 4,832 MBOE with improved proved developed reserves of 1,931 MBOE. PUD revisions are a result of (1) removal ofapproximately 2,011 MBOE of reserves due to delayed development plans of other operators in the Midland Basin that managementpreviously expected to be developed within five years, (2) reduction of 2,378 MBOE upon closing of the Bold Transaction and makingadjustments to development plans and PUD reserve assignments, and (3) non-participation in three Eagle Ford natural gas PUDs that wereexpected to develop 443 MBOE. Positive revisions are primarily a result of increased oil and natural gas prices during 2017.Proved Undeveloped ReservesProved undeveloped reserves ("PUDs") increased from 60,015 MBOE to 75,201 MBOE or 25%, for the year ended December 31, 2018 compared to the yearended December 31, 2017. PUDs represent 76% of our total proved reserves. Certain previously booked PUDs were reclassified as proved developed reservesdue to successful drilling efforts. Revisions of prior estimates include certain PUDs that were reclassified to unproved categories due to development planchanges. In accordance with our 2018 year-end independent engineering reserve report, we plan to drill all of our individual PUD drilling locations withinthe next five years.Changes in our PUD reserves for the years ended December 31, 2018 and 2017 were as follows (in MBOE):Proved undeveloped reserves at January 1, 20172,690Conversions to developed(2,756)Extensions and discoveries27,977Sales of minerals in place(391)Purchases of minerals in place37,327Revision to previous estimates(4,832) Proved undeveloped reserves at December 31, 2017 (1)60,015Conversions to developed(4,419)Extensions and discoveries13,734Sales of minerals in place(4,702)Purchases of minerals in place4,735Revision to previous estimates5,838Proved undeveloped reserves at December 31, 2018 (2)75,20140Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

In our year-end 2017 plan to develop our PUDs within five years, we estimated that $51.9 million of capital would be expended in2018 and that it would convert 4.3 MMBOE, which was consistent with the $55.4 million actually spent to convert 4.4 MMBOE to developed.Extensions and discoveries. Additionally, 13.7 MMBOE were added as extensions and discoveries due to successful drilling results on our acreage positionsbecause of the wells we drilled. The increase was also supported by successful drilling results by other operators directly offsetting and in close proximity toour acreage. All of these drilling results increased the confidence of the reservoir continuity and performance of the associated reservoirs which increased thenumber of PUDs primarily in the Midland Basin.Sales of minerals in place. Sales of minerals in place totaled 4.7 MMBOE during 2018, which consisted of 3.7 MMBOE resulting from the disposition ofnon-operated properties in the Midland Basin as part of an acreage trade and 1.0 MMBOE related to the disposition of non-operated Eagle Ford properties,both further described in Note 3. Acquisitions and Divestitures in the Notes to Consolidated Financial Statements.Purchases of minerals in place. In 2018, purchases of minerals in place of 4.7 MMBOE were attributable to developed non-producing wells and undevelopedacreage acquired in the Midland Basin as part of an acreage trade, as further described in Note 3. Acquisitions and Divestitures in the Notes to ConsolidatedFinancial Statements.Revision to previous estimates. Revisions of 5.8 MMBOE were primarily due to our successful drilling efforts in the Midland Basin as well as improvedcommodity prices. 2017 Changes in Proved Undeveloped ReservesConversions to developed. In our year-end 2016 plan to develop our PUDs within five years, we estimated that $6.9 million of capital would be expended in2017 and that it would convert 732 MBOE. Because of the improvement in commodity prices and the change in its development plan for 2017, we actuallyspent $8.5 million to convert 622 MBOE to developed. Our plan changed in that we developed more oil PUDs and elected not to participate in natural gasPUDs which included the above mentioned 443 MBOE associated with the Eagle Ford non-participation. The capital to develop our oil PUDs was higher ona per unit basis than the natural gas PUDs however the margins are higher for oil PUDs. The oil PUDs further benefited our longer-term operated developmentplans. Since the Bold Transaction closed in May 2017, the associated capital plan for the properties acquired in the Bold Transaction during 2017 was notconsidered in our year-end 2016 report. We did however incur $63.4 million to convert 2,134 MBOE of purchased PUD reserves to developed.Extensions and discoveries. Additionally, 27,977 MBOE were added as extensions and discoveries due to successful drilling results on our acreage positionsbecause of the wells we drilled. The increase was also supported by successful drilling results by other operators directly offsetting and in close proximity toour acreage. All of these drilling results increased the confidence of the reservoir continuity and performance of the associated reservoirs which increased thenumber of PUDs primarily in the Midland Basin.Sales of minerals in place. Sales of minerals in place totaled 391 MBOE during 2017 and were primarily related to the disposition of the Bakken properties,as further described in Note 3. Acquisitions and Divestitures to the Notes to Consolidated Financial StatementsPurchases of minerals in place. During 2017, 37,327 MBOE were added to PUD reserves upon the closing of the Bold Transaction.Revision to previous estimates. Revisions of 4,832 MBOE were primarily due to (1) removal of approximately 2,011 MBOE of reserves due to delayeddevelopment plans of other operators in the Midland Basin that management previously expected to be developed within five years, (2) reduction of 2,378MBOE upon the closing of the Bold Transaction and making adjustments to development plans and PUD reserve assignments, and (3) non-participation inthree Eagle Ford natural gas PUDs that were expected to develop 443 MBOE. This non-participation has no impact on our ability to participate in futurewells in this acreage position. 41Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

These production volumes, inflows, expenses, developmentcosts and cash flows are limited to the PUD reserves and do not include any production or cash flows from the Proved Developed categorywhich will also help to fund our capital program.(2)Barrels of oil equivalent have been calculated on the basis of six thousand cubic feet (Mcf) of natural gas equal to one barrel of oilequivalent (BOE).(3)Computation is based on SEC pricing of (i) $61.18 per Bbl (WTI-Cushing spot prices, adjusted for differentials) and (ii) $2.13 per Mcf(Henry Hub spot natural gas price), as adjusted for location and quality by property.Historically, our drilling programs have been substantially funded from our cash flow and borrowings under our credit facility. Based on current commodityprices and our current expectations over the next five years of our cash flows and drilling programs, which includes drilling of proved undeveloped andunproven locations, we believe that we can continue to substantially fund our drilling activities from our cash flow and with borrowings under the EEHCredit Agreement. In addition, historically, we have been able to take advantage of the capital markets, as needed, when opportunities arose.Preparation of Reserve EstimatesWe engaged an independent petroleum engineering consulting firm, CG&A, to prepare our annual reserve estimates and we have relied on CG&A’s expertiseto 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 honorsfrom the University of Texas at Austin in 1989 with a Bachelor of Science degree in Petroleum Engineering. Mr. Brooker is a Registered ProfessionalEngineer 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.Robert J. Anderson, our President, is responsible for reservoir engineering, is a qualified reserve estimator and auditor and is primarily responsible foroverseeing CG&A during the preparation of our annual reserve estimates. His professional qualifications meet or exceed the qualifications of reserveestimators and auditors set forth in the “Standards Pertaining to Estimation and Auditing of Oil and Natural Gas Reserves Information” promulgated by theSociety of Petroleum Engineers. His qualifications include a Bachelor of Science degree in Petroleum Engineering from the University of Wyoming in 1986;a Master of Business Administration degree from the University of Denver in 1988; member of the Society of Petroleum Engineers since 1985; and more than32 years of practical experience in estimating and evaluating reserve information with more than fifteen of those years being in charge of estimating andevaluating reserves.We maintain adequate and effective internal controls over our reserve estimation process as well as the underlying data upon which reserve estimates arebased. The primary inputs to the reserve estimation process are technical information, financial data, ownership interest and production data. The relevantfield 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 externalquarterly reviews, annual audits and our own set of internal controls over financial reporting. Internal controls over financial reporting are assessed foreffectiveness annually using criteria set forth in Internal Control – Integrated Framework, (2013 Version) issued by the Committee of SponsoringOrganizations of the Treadway Commission.

Our current ownership in mineral interests and well production data are also subject to our internal controls overfinancial reporting, and they are incorporated in our reserve database as well and verified internally by our personnel to ensure their accuracy andcompleteness. Once the reserve database has been updated with current information, and the relevant technical support material has been assembled, CG&Ameets with our technical personnel to review field performance and future development plans in order to further verify the validity of estimates. Followingthese reviews, the reserve database is furnished to CG&A so that it can prepare its independent reserve estimates and final report. The reserve estimatesprepared by CG&A are reviewed and compared to our internal estimates by our President. Material reserve estimation differences are reviewed betweenCG&A and us, and additional data is provided to address the differences. If the supporting documentation will not justify additional changes, the CG&Areserves are accepted. In the event that additional data supports a reserve estimation adjustment, CG&A will analyze the additional data, and may makechanges it solely deems necessary. Additional data is usually comprised of updated production information on new wells. Once the review is completed andall material differences are reconciled, the reserve report is finalized and our reserve database is updated with the final estimates provided by CG&A.Net Oil, Natural Gas and Natural Gas Liquids Production, Average Price and Average Production CostThe net quantities of oil, natural gas and natural gas liquids produced and sold by us for the years ended December 31, 2018 and 2017, the average sales priceper unit sold and the average production cost per unit are presented below: Years Ended December 31, 2018 2017Sales Volumes: Oil (MBbl)2,370 1,828Natural gas (MMcf)3,610 3,260Natural gas liquids (MBbl)655 500Barrels of oil equivalent (MBOE)*3,627 2,872Average daily production (BOE per day)9,937 7,869Average prices realized:** Oil (per Bbl)$59.40 $48.43Natural gas (per Mcf)$2.05 $2.69Natural gas liquids (per Bbl)$26.23 $21.51Barrels of oil equivalent (per BOE)$45.59 $37.63Production cost per BOE$5.66 $6.84*Barrels of oil equivalent have been calculated on the basis of six thousand cubic feet (Mcf) of natural gas equal to one barrel of oilequivalent (BOE).**Amounts exclude the impact of cash paid/received on settled derivative contracts as we did not elect to apply hedge accounting.

Our operations are all in the upstreamsegment 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 ofwest 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-ownedconsolidated subsidiaries, “EEH”), with a controlling interest in EEH. Earthstone, together with its wholly-owned subsidiary, Lynden Corp, and LyndenCorp’s wholly-owned consolidated subsidiary, Lynden US and also a member of EEH, consolidates the financial results of EEH and records a noncontrollinginterest 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).Areas of OperationOur primary focus is concentrated in the Midland Basin of west Texas, a high oil and liquids rich resource which provides us with multiple horizontal targethorizons, extensive production histories, long-lived reserves and historically high drilling success rates. Midland BasinWe believe that the Midland Basin continues to have attractive economics and we expect to continue to focus our attention on growing our footprint throughdevelopment drilling, acreage trades, asset acquisitions, and corporate merger and acquisition opportunities.We have been operating a one drilling rig program in the Midland Basin and plan to maintain a one rig program throughout 2019. In January 2019, weconcluded drilling the second well on a two-well pad in Upton County and moved the rig to Midland County to drill five wells in our Mid-States Unit. Webegan completing three wells in February 2019 and expect to begin completing the five Mid-States wells in June 2019.We continue to be active in acreage trades and acquisitions in the Midland Basin which generally allow for longer laterals, increased operated inventory andgreater operating efficiency.Eagle Ford TrendWe drilled five wells in southern Gonzales County, Texas in 2018 and completed 11 wells in the area during the year. We expect to drill seven wells in thisarea during 2019 and may consider additional drilling based on improvement in the commodity prices.Terminated Contribution AgreementAs previously disclosed in our Current Report on Form 8-K filed on October 17, 2018 with the SEC, on October 17, 2018, Earthstone, EEH and SabaloHoldings entered into the Contribution Agreement which provided for the Sabalo Acquisition. On December 21, 2018, Earthstone, EEH and Sabalo Holdingsentered into the Termination Agreement, pursuant to which the parties mutually agreed to terminate the Contribution Agreement.In connection with the Termination Agreement, Earthstone, EEH and Sabalo Holdings also agreed to release each other from certain claims and liabilitiesarising out of or related to the Contribution Agreement and the transactions contemplated therein or thereby. In addition, we estimated total transaction coststo be approximately $13.4 million, including payment to Sabalo Holdings of $1.6 million for reimbursement of expenses. All other related agreements werealso terminated in conjunction with the termination of the Contribution Agreement.Midland Basin Acreage Trade48Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Under the terms of the Exchange, we acquired 3,899 net operated acres in Reagan County with virtually a100% working interest, in exchange for 1,222 net non-operated acres in Glasscock County with an average working interest of 39% and $27.8 million incash, plus customary closing adjustments. The effective date of the transaction was September 1, 2018.Along with the net increase of 2,677 acres, the trade also resulted in a net production increase of approximately 350 Boe/d. The producing wells acquired inthis trade are connected into a third-party crude oil pipeline gathering system, which will assure flow capacity for this production as well as any volumes fromfuture wells on this acreage. For further discussion, see Note 3. Acquisitions and Divestitures in the Notes to Consolidated Financial Statements included inthis report.Bold TransactionOn May 9, 2017, Earthstone completed the Bold Contribution Agreement. The purpose of the Bold Contribution Agreement was to provide for, among otherthings described below, the business combination between Earthstone and Bold, which owned significant developed and undeveloped oil and natural gasproperties in the Midland Basin of Texas (the “Bold Transaction”).The Bold Transaction was structured in a manner commonly known as an “Up-C.” Under this structure and the Bold Contribution Agreement, (i) Earthstonerecapitalized its common stock into two classes - Class A Common Stock and Class B Common Stock, and all of Earthstone’s existing outstanding CommonStock, was recapitalized on a one-for-one basis for Class A Common Stock (the “Recapitalization”); (ii) Earthstone transferred all of its membership interestsin Earthstone Operating, LLC, Sabine River Energy, LLC, EF Non-Op, LLC and Earthstone Legacy Properties, LLC (formerly Earthstone GP, LLC) and$36,071 in cash from the sale of Class B Common Stock to Bold Holdings (collectively, the “Earthstone Assets”) to EEH, in exchange for 16,791,296 EEHUnits; (iii) Lynden US transferred all of its membership interests in Lynden Op to EEH in exchange for 5,865,328 EEH Units; (iv) Bold Holdings transferredall of its membership interests in Bold to EEH in exchange for 36,070,828 EEH Units and purchased 36,070,828 shares of Class B Common Stock issued byEarthstone for $36,071; and (v) Earthstone granted an aggregate of 150,000 fully vested shares of Class A Common Stock under the 2014 Plan, to certainemployees of Bold. Each EEH Unit, together with one share of Class B Common Stock, are convertible into one share of Class A Common Stock.49Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Of theincrease, approximately $20.0 million was attributable to an increase in our realized price and $32.2 million was attributable to increased volume. Ouraverage realized price per Bbl increased from $48.43 for the year ended December 31,50Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

We had a net increase in the volume of oil sold of 542 MBbls or 30%, primarily due to theBold properties acquired on May 9, 2017 representing a partial prior year, partially offset by the impact of non-core asset divestitures that took place in thethird and fourth quarters of 2017.Natural gas revenuesFor the year ended December 31, 2018, natural gas revenues decreased by $1.4 million or 16% relative to the comparable period in 2017. Of the decrease,approximately $2.1 million was attributable to a decrease in our realized price, partially offset by an increase of $0.7 million attributable to increasedvolume. Our average realized price per Mcf decreased from $2.69 for the year ended December 31, 2017 to $2.05 or 24% for the year ended December 31,2018. The total volume of natural gas produced and sold increased 350 MMcf or 11% primarily due to increased production at our Midland Basin propertiesas well as the impact of the timing of the Bold Transaction, partially offset by the impact of non-core asset divestitures that took place in the third and fourthquarters of 2017.Natural gas liquids revenuesFor the year ended December 31, 2018, natural gas liquids revenues increased by $6.4 million or 60% relative to the comparable period in 2017. Of theincrease, approximately $2.3 million was attributable to an increase in our realized price and $4.1 million was attributable to increased volume. The volumeof natural gas liquids produced and sold increased by 155 MBbls or 31%, primarily due to the timing of the Bold Transaction which substantially increasedour Midland Basin properties on May 9, 2017, partially offset by the impact of non-core asset divestitures that took place in the third and fourth quarters of2017.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 suchas labor, repairs and maintenance, re-engineering and workovers, equipment rentals, materials and supplies, fuel and chemicals, LOE includes productmarketing and transportation fees, insurance, ad valorem taxes and overhead charges provided for in operating agreements.LOE increased by $0.9 million or 4% for the year ended December 31, 2018 relative to the comparable period in 2017. The increase in LOE was due to a $1.9million increase related to the Bold properties acquired on May 9, 2017 representing a partial prior year and a $4.4 million increase related to the increasednumber of producing wells resulting from our 2018 drilling program, offset by a $5.4 million decrease related to non-core asset divestitures that took place inthe third and fourth quarters of 2017.Severance taxesSeverance taxes for the year ended December 31, 2018 increased by $2.0 million or 33% relative to the comparable period in 2017, primarily due to theincreased prices of oil and natural gas liquids, partially offset by the impact of non-core asset divestitures that took place in the third and fourth quarters of2017. However, as a percentage of revenues from oil, natural gas, and natural gas liquids, severance taxes remained flat when compared to the prior yearperiod.ImpairmentDuring the year ended December 31, 2018, we recorded non-cash asset impairments of $4.6 million to our unproved oil and natural gas properties resultingfrom certain acreage expirations related to our Eagle Ford Trend properties. During the year ended December 31, 2017, we recognized $72.2 million of non-cash asset impairments as a result of significant forward commodity price declines and the recording of certain acreage expirations that negatively impactedour results of operations and equity. These impairments consisted of $63.1 million to our proved oil and natural gas properties and $9.1 million to ourunproved oil and natural gas properties, primarily to our properties located in the Eagle Ford Trend. See Note 7. Oil and Natural Gas Properties in the Notesto 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, 2018 by $10.7 million, or 29% relative to the comparable period in 2017, due to the addition of the assetsacquired in the Bold Transaction to the depletable base, as well as increased production volumes, partially offset by the impact of non-core asset divestituresthat took place in the third and fourth quarters of 2017.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 $1.1 millionfor the year ended December 31, 2018 relative to the comparable period in 2017, primarily due to the51Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

During the year ended December 31, 2017, we recorded $4.7 million in transaction costs primarily associated with the Bold Transactioncompleted in May 2017. See Note 3. Acquisitions and Divestitures in the Notes to Consolidated Financial Statements.Interest expense, netInterest expense includes commitment fees, amortization of deferred financing costs, and interest on outstanding indebtedness. Interest expense for the yearended December 31, 2018 was $2.9 million compared to $2.7 million for the comparable period in 2017. The $0.2 million increase in interest expense wasprimarily due to higher average borrowings outstanding compared to the prior year period. See Note 13. Long-Term Debt in the Notes to ConsolidatedFinancial Statements.Gain on sale of oil and gas properties, netDuring the year ended December 31, 2018, we sold certain non-core oil and gas properties including our non-operated Eagle Ford assets located in southTexas, recording gains totaling $1.9 million. During the year ended December 31, 2017, we sold all of our oil and natural gas leases, oil and natural gas wellsand associated assets located in the Williston Basin in North Dakota. We also sold certain of our non-core oil and natural gas properties in Texas, Montana,Oklahoma and North Dakota. In connection with these sales, we recorded gains totaling $9.1 million. See Note 3. Acquisitions and Divestitures in the Notesto Consolidated Financial Statements.Gain (loss) on derivative contracts, netFor the year ended December 31, 2018, we recorded a net gain on derivative contracts of $60.9 million, consisting of unrealized mark-to-market gains of$76.0 million, partially offset by net realized losses on settlements of $15.1 million. For the year ended December 31, 2017, we recorded a net loss onderivative contracts of $8.0 million, consisting of unrealized mark-to-market losses of $7.3 million and net realized losses on settlements of $0.7 million.Litigation SettlementFor the year ended December 31, 2018, we recorded an expense of $4.7 million related to the settlement of certain litigation. See Note 16. Commitments andContingencies in the Notes to Consolidated Financial Statements.Income tax (expense) benefitDuring the year ended December 31, 2018, we recorded total income tax expense of $2.5 million which included (1) deferred income tax expense for LyndenUS of $1.9 million as a result of its share of the distributable income from EEH, offset by a $0.5 million discrete income tax benefit related to refundable AMTtax credits resulting from the TCJA, (2) deferred income tax expense for Earthstone of $7.4 million as a result of its share of the distributable income fromEEH, which was used to reduce the valuation allowance recorded against its deferred tax asset as future realization of the net deferred tax asset cannot beassured and (3) deferred income tax expense of $1.1 million related to the Texas Margin Tax. Lynden Corp incurred no material income or loss, or relatedincome tax expense or benefit, for the year ended December 31, 2018. During the year ended December 31, 2017, we recorded a total income tax benefit of $16.4 million which included (1) income tax benefit of $8.6 million, ofwhich $4.8 million related to the reduction of that amount in its deferred tax liability resulting from the federal corporate income tax rate reduction to 21%,(2) a $7.7 million income tax benefit for Earthstone as a discrete item during the current reporting period, which resulted from a change in assessment of therealization of its net deferred tax assets due to the deferred tax liability that was recorded with respect to its investment in EEH as part of the Bold Transactionas an adjustment to Additional paid-in capital in the Consolidated Statement of Equity, and (3) income tax expense of $12.6 million related to the reductionof the amount in its deferred tax asset resulting from the federal corporate income tax rate reduction to 21% which was fully offset by the reduction in itsvaluation allowance for that amount because the future realization of such loss cannot be reasonably assured and is subject to a full valuation allowance.Lynden Corp incurred no material income or loss, or related income tax expense or benefit, for the year ended December 31, 2017.Liquidity and Capital Resources52Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Drilling horizontal wells, generally consisting of 7,500 to 12,000-foot lateral lengths,in the Midland Basin is capital intensive. At December 31, 2018, we had approximately $0.4 million in cash and approximately $196.2 million in unusedborrowing capacity under the EEH Credit Agreement (discussed below) for a total of approximately $196.5 million in funds available for operational andcapital funding. We currently estimate 2019 capital expenditures will be approximately $190 million, which assumes a 16-well program running one rig forour operated acreage in the Midland Basin and a seven-well program for our operated Eagle Ford acreage as well as estimated expenditures for our non-operated Midland Basin properties and land and infrastructure activities. We likely will continue to outspend our cash flows provided by operating activitiesover at least the next 12 months from the date of this report based on current assumptions. However, we believe we will have sufficient liquidity with cashflows from operations and borrowings under the EEH Credit Agreement for the next 12 months in order to meet our cash requirements. We may considervarious financial arrangements or other techniques or transactions, including but not limited to promoted drilling arrangements.Working Capital, defined as Total current assets less Total current liabilities as set forth in our Consolidated Balance Sheets, was a deficit of $18.3 million asof December 31, 2018 compared to a deficit of $21.8 million as of December 31, 2017. We used $150.0 million to fund our capital program, in addition to$32.6 million to acquire additional oil and natural gas properties, offset by $6.0 in cash proceeds from the disposition of certain non-core oil and natural gasproperties in the Eagle Ford Trend, that was facilitated by $102.4 million of net cash provided by our operating activities resulting from increased oil pricesas well as increased production resulting from our 2018 drilling and development program, net borrowings of $53.8 million under the EEH Credit Agreementand a reduction of our cash on hand by $22.6 million. Due to the costs incurred related to our drilling program, we may incur additional working capitaldeficits in the future. We expect that our pace of development, production volumes, commodity prices and differentials to NYMEX prices for our oil andnatural gas production will continue to be the largest variables affecting our working capital.We expect to finance future acquisition and development activities through available working capital, cash flows from operating activities, borrowings underthe EEH Credit Agreement and, various means of corporate and project financing, assuming we can effectively access debt and equity markets. In addition, asindicated above, we may continue to partially finance our drilling activities through the sale of participating rights to financial institutions or industryparticipants, and we could structure such arrangements on a promoted basis, whereby we may earn working interests in reserves and production greater thanour proportionate share of capital costs.Capital ExpendituresWe have set our 2019 capital budget, which assumes a one-rig operated program and non-operated activities as currently proposed by operators, for ouracreage in the Midland Basin as well as a seven-well program on our operated Eagle Ford acreage. Our anticipated capital expenditures for 2019 are currentlyestimated at $190 million.Our accrual basis capital expenditures for the years ended December 31, 2018 and 2017 were as follows: Years Ended December 31, 2018 2017Drilling and completions$151,059 $76,253Leasehold costs2,102 3,067Land— 1,816Total capital expenditures$153,161 $81,136In addition to the capital expenditures described above, on October 5, 2018, we closed the Exchange. Under the terms of the Exchange, we acquired 3,899net operated acres in Reagan County with virtually a 100% working interest, including producing assets representing a net production increase ofapproximately 350 Boe/d, in exchange for 1,222 net non-operated acres in Glasscock County with an average working interest of 39% and $27.8 million incash, plus customary closing adjustments.For further discussion, see Note 3. Acquisitions and Divestitures to the Notes to Consolidated Financial Statements included in this report.Credit AgreementOn November 6, 2018, in connection with a regularly scheduled borrowing base redetermination, the borrowing base under the EEH Credit Agreement wasincreased from $225.0 million to $275.0 million. As of December 31, 2018, we had $78.8 million of borrowings outstanding, bearing annual interest of4.479%, resulting in a remaining $196.2 million of borrowing base available under the EEH Credit Agreement.Impairments to Oil and Natural Gas Properties53Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

(2)We have a non-cancelable fixed cost agreement of $1.6 million per year through May 2021 to reserve pipeline capacity of 10,000 MMBtuper day for gathering and processing related to certain Eagle Ford assets in south Texas. As the operator of the properties dedicated to thiscontract, the gross amount of obligation is provided, however our net share is approximately 31%.Environmental RegulationsOur operations are subject to risks normally associated with the exploration for and the production of oil and natural gas, including blowouts, fires, andenvironmental 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 suchwells were drilled or during such time the wells were operated. We maintain comprehensive insurance coverage that we believe is adequate to mitigate therisk 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 couldstill 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 theviolation of any rules or regulations relating thereto.Critical Accounting Policies and EstimatesOur discussion of financial condition and results of operations is based upon the information reported in our consolidated financial statements. Thepreparation of these statements requires us to make certain assumptions and estimates that affect the reported amounts of assets, liabilities, revenues andexpenses as well as the disclosure of contingent assets and liabilities at the date of our financial statements. We base our assumptions and estimates onhistorical experience and other sources that we believe to be reasonable at the time. Actual results may vary from our estimates due to changes incircumstances, weather, politics, global economics, mechanical problems, general business conditions and other risks. We have outlined below certain ofthese policies as being of particular importance to the portrayal of our financial position and results of operations and which require the application ofsignificant judgment by our management.Oil and Natural Gas PropertiesWe use the successful efforts method of accounting for oil and natural gas operations. Under this method, costs to acquire oil and natural gas properties, drillsuccessful exploratory wells, drill and equip development wells, and install production facilities are capitalized. Exploration costs, including unsuccessfulexploratory wells, geological and geophysical are charged to operations as incurred. Depreciation, depletion and amortization of the leasehold anddevelopment costs that are capitalized for proved oil and natural gas properties are computed using the units-of-production method, at the field level, basedon total proved reserves and proved developed reserves, respectively, as estimated by independent petroleum engineers. Oil and natural gas properties areperiodically assessed for impairment whenever changes in facts and circumstances indicate a possible significant deterioration in the future cash flowsexpected 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 areidentifiable 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 arelocated within the continental United States.Oil and Natural Gas Reserve QuantitiesReserve quantities and the related estimates of future net cash flows affect our periodic calculations of depletion, impairment of our oil and natural gasproperties, and asset retirement obligations. Proved oil and natural gas reserves are the estimated quantities of oil, natural gas and natural gas liquids whichgeological and engineering data demonstrate with reasonable certainty to be recoverable in future periods from known reservoirs under existing economicand operating conditions. Reserve quantities and55Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely. The user assumes all risks for any damages or losses arising from any use of this information,except to the extent such damages or losses cannot be limited or excluded by applicable law. Past financial performance is no guarantee of future results.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 independentpetroleum engineers evaluated 100% of our estimated proved reserve quantities and their related future net cash flows as of December 31, 2018. Estimatesprepared by others may be higher or lower than our estimates. Because these estimates depend on many assumptions, all of which may differ substantiallyfrom actual results, reserve estimates may be different from the quantities of oil and natural gas that are ultimately recovered. We make revisions to reserveestimates throughout the year as additional information becomes available. We make changes to depletion rates, impairment calculations, and assetretirement obligations in the same period that changes to reserve estimates are made.Depreciation, Depletion and AmortizationOur rate of recording DD&A is dependent upon our estimates of total proved and proved developed reserves, which estimates incorporate variousassumptions and future projections. If the estimates of total proved or proved developed reserves decline, the rate at which we record DD&A expenseincreases, reducing our net income. Such a decline in reserves may result from lower commodity prices, which may make it uneconomic to drill for andproduce higher cost fields. We are unable to predict changes in reserve quantity estimates as such quantities are dependent on the success of our exploitationand development program, as well as future economic conditions.Impairment of Oil and Natural Gas PropertiesWe review the value of our oil and natural gas properties whenever management judges that events and circumstances indicate that the recorded carryingvalue of properties may not be recoverable. Impairments of producing properties are determined by comparing the pretax future net undiscounted cash flowsto 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 costsconsistent with those used for internal decision making. Different pricing assumptions or discount rates could result in a different calculated impairment. Weprovide for impairments on significant undeveloped properties when we determine that the property will not be developed or a permanent impairment invalue has occurred.Asset Retirement ObligationOur asset retirement obligations (“AROs”) consist primarily of estimated future costs associated with the plugging and abandonment of oil and natural gaswells, removal of equipment and facilities from leased acreage, and land restoration in accordance with applicable local, state and federal laws. Thediscounted fair value of an ARO liability is required to be recognized in the period in which it is incurred, with the associated asset retirement costcapitalized as part of the carrying cost of the oil and natural gas asset. The recognition of an ARO requires that management make numerous assumptionsregarding such factors as the estimated probabilities, amounts and timing of settlements; the credit-adjusted risk-free rate to be used; inflation rates; andfuture advances in technology. In periods subsequent to the initial measurement of the ARO, we must recognize period-to-period changes in the liabilityresulting 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 AROliability due to passage of time impact net income as accretion expense. The related capitalized cost, including revisions thereto, is charged to expensethrough DD&A over the life of the field.Derivative Instruments and Hedging ActivityWe are exposed to certain risks relating to our ongoing business operations, such as commodity price risk. Derivative contracts are utilized to economicallyhedge our exposure to price fluctuations and reduce the variability in our cash flows associated with anticipated sales of future oil and natural gasproduction. We follow FASB ASC Topic 815, Derivatives and Hedging, to account for our derivative financial instruments. We do not enter into derivativecontracts for speculative trading purposes. It is our policy to enter into derivative contracts only with counterparties that are creditworthy financialinstitutions 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 betweenfixed 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 derivative56Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

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 PositionsWe are a U.S. company operating in Texas, as of December 31, 2018, 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 andincome is earned. The income tax rates imposed and methods of computing taxable income in these jurisdictions vary. Therefore, as a part of the process ofpreparing the consolidated financial statements, we are required to estimate the income taxes in each of these jurisdictions. This process involves estimatingthe actual current tax exposure together with assessing temporary differences resulting from differing treatment of items, such as depreciation, amortizationand certain accrued liabilities for tax and accounting purposes. Our effective tax rate for financial statement purposes will continue to fluctuate from year toyear 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 theLynden 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 USrecord 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 orloss 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 leveland only recognizes 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 berealized. At December 31, 2018 and 2017, the Company has recorded a valuation allowance for its 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 incometaxes by prescribing a minimum recognition threshold that a tax position is required to meet before being recognized in the consolidated financialstatements. It requires that we recognize in the consolidated financial statements the financial effects of a tax position, if that position is more likely than notof being sustained upon examination, including resolution of any appeals or litigation processes, based upon the technical merits of the position. It alsoprovides guidance on measurement, classification, interest, penalties and disclosure. Our tax positions related to our pass-through status and state income taxliability, including deductibility of expenses, have been reviewed by our management and they believe those positions would more likely than not besustained upon examination. Accordingly, we have not recorded an income tax liability for uncertain tax positions at December 31, 2018 or 2017.Revenue RecognitionWe predominantly derive our revenue from the sale of produced oil, natural gas and natural gas liquids. Revenues are recognized when the recognitioncriteria of FASB ASC Topic 606, Revenue from Contracts with Customers, are met, which generally occurs at the point in which title passes to thecustomers. We receive payment from one to three months after delivery. At the end of each quarter, we estimate the amount of production delivered topurchasers and the price we will receive. Variances between our estimated revenue and actual payment are recorded in the month the payment isreceived. Historically, however, differences have been insignificant.Accounting for Business CombinationsOur business has grown substantially through acquisitions, and our business strategy is to continue to pursue acquisitions as opportunities arise. We haveaccounted 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 considerationgiven. The assets and liabilities acquired are measured at their fair value including the recognition of acquisition-related costs that are separate from theacquired 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, ifany, over the net amounts assigned to assets acquired and liabilities assumed is recognized as goodwill. The excess of the fair value of assets acquired andliabilities 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 tocertain 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 havefair values that are readily determinable. Different techniques may be used to determine fair values, including market prices (where available), appraisals, andcomparison to transactions for similar assets and liabilities, and present value of57Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Since these estimates involve the use of significant judgment, they can change as new information becomesavailable.GoodwillWe account for goodwill in accordance with FASB ASC Topic 350, Intangibles – Goodwill and Other. Goodwill represents the excess of the purchase priceover 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 beevaluated 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 ourgoodwill such as, industry and market conditions, including commodity prices, costs factors, and other company specific events. If we conclude that it is notmore 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 afterassessing 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 itscarrying amount, the two-step goodwill test is performed. The two-step goodwill impairment test is also performed whenever events or changes incircumstances indicate that the carrying value may not be recoverable. If, after performing the two-step goodwill test, it is determined that the carrying valueof 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 determinedto be impaired Noncontrolling InterestWe account for noncontrolling interest in accordance with FASB ASC Topic 810, Consolidation, which requires the recording of a noncontrolling interestcomponent of Net income (loss), as well as a noncontrolling interest component within equity. Noncontrolling interest represents third-party equityownership of EEH and is presented as a component of equity in the Consolidated Balance Sheet as of December 31, 2018 and 2017, as well as an adjustmentto Net loss in the Consolidated Statement of Operations for the years ended December 31, 2018 and 2017.As of December 31, 2018, Earthstone and Lynden US held 44.7% of the outstanding membership interests in EEH while Bold Holdings, the noncontrollingparty, held the remaining 55.3%.

As describedbelow under paragraph (b) within Management’s Annual Report on Internal Control over Financial Reporting, our Chief Executive Officer and PrincipalAccounting Officer have concluded that, as of the end of the period covered by this Annual Report on Form 10-K, our disclosure controls and procedureswere 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 theExchange Act is recorded, processed, summarized and reported within the time periods specified by the SEC’s rules and that such information is accumulatedand communicated to our management, including our Chief Executive Officer and Principal Accounting Officer, as appropriate to allow timely decisionsregarding 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 unqualifiedopinion on our consolidated financial statements.(b) Management’s Annual Report on Internal Control over Financial ReportingOur 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 financialreporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Our internal controlover 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 withgenerally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations ofour management; and•provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets thatcould 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 overfinancial reporting may not prevent or detect every misstatement and instance of fraud. Controls are susceptible to manipulation, especially in instances offraud caused by collusion of two or more people.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reportingas of December 31, 2018, 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”), theconsolidated balance sheet of Earthstone Energy, Inc. and subsidiaries as of December 31, 2018, the related consolidated statements ofoperations, equity and cash flows for the year then ended, and the related notes (collectively referred to as the “consolidated financial statements”)and our report dated March 12, 2019 expressed an unqualified opinion on those consolidated financial statements.Basis for OpinionThe Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of theeffectiveness of internal control over financial reporting, included in the accompanying Management Report on Internal Control over FinancialReporting included in Item 9A. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on ouraudit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordancewith 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 obtainreasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit includedobtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing andevaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such otherprocedures 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 ReportingA company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financialreporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Acompany’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, inreasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurancethat transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accountingprinciples, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directorsof the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition ofthe 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 anyevaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or thatthe degree of compliance with the policies or procedures may deteriorate./s/ Moss Adams, LLPHouston, Texas60Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

In addition, the Company is active in corporate mergers and the acquisition of oiland natural gas properties that have production and future development opportunities. The Company’s operations are all in the up-stream segment of the oiland 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-ownedconsolidated subsidiaries, “EEH”), with a controlling interest in EEH. Earthstone, together with its wholly-owned subsidiary, Lynden Energy Corp., acorporation organized under the laws of British Columbia (“Lynden Corp”), and Lynden Corp’s wholly-owned consolidated subsidiary, Lynden USA Inc., aUtah corporation (“Lynden US”) and also a member of EEH, consolidates the financial results of EEH and records a noncontrolling interest in theConsolidated Financial Statements representing the economic interests of EEH's members other than Earthstone and Lynden US. Certain prior period amounts have been reclassified to conform to current period presentation within the Consolidated Financial Statements. Prior period Re-engineering and workovers in the Consolidated Statements of Operations have been reclassified from its own line item and included in Lease operatingexpenses, within Operating Costs and Expenses, to conform to current period presentation. Additionally, prior-period Stock-based compensation in theConsolidated Statements of Operations has been reclassified from its own line item and included in General and administrative expense, within OperatingCosts and Expenses, to conform to current-period presentation. These reclassifications had no effect on Income (loss) from operations or any other subtotal inthe Consolidated Statements of Operations.Bold Contribution AgreementOn May 9, 2017, Earthstone completed a contribution agreement dated as of November 7, 2016 and as amended on March 21, 2017 (the “Bold ContributionAgreement”), by and among Earthstone, EEH, Lynden US, Lynden USA Operating, LLC, a Texas limited liability company (“Lynden Op”), Bold EnergyHoldings, LLC, a Texas limited liability company (“Bold Holdings”), and Bold Energy III LLC, a Texas limited liability company (“Bold”). The purpose ofthe Bold Contribution Agreement was to provide for, among other things described below, the business combination between Earthstone and Bold, whichowned significant developed and undeveloped oil and natural gas properties in the Midland Basin of Texas (the “Bold Transaction”).The Bold Transaction was structured in a manner commonly known as an “Up-C.” Under this structure and the Bold Contribution Agreement, (i) Earthstonerecapitalized its common stock into two classes – Class A common stock, $0.001 par value per share (the “Class A Common Stock”), and Class B commonstock, $0.001 par value per share (the “Class B Common Stock”), and all of Earthstone’s existing outstanding common stock, $0.001 par value per share (the“Common Stock”), was recapitalized on a one-for-one basis for Class A Common Stock (the “Recapitalization”); (ii) Earthstone transferred all of itsmembership interests in Earthstone Operating, LLC, Sabine River Energy, LLC, EF Non-Op, LLC and Earthstone Legacy Properties, LLC (formerlyEarthstone GP, LLC) and $36,071 in cash from the sale of Class B Common Stock to Bold Holdings (collectively, the “Earthstone Assets”) to EEH, inexchange for 16,791,296 membership units of EEH (the “EEH Units”); (iii) Lynden US transferred all of its membership interests in Lynden Op to EEH inexchange for 5,865,328 EEH Units; (iv) Bold Holdings transferred all of its membership interests in Bold to EEH in exchange for 36,070,828 EEH Units andpurchased 36,070,828 shares of Class B Common Stock issued by Earthstone for $36,071; and (v) Earthstone granted an aggregate of 150,000 fully vestedshares of Class A Common Stock under Earthstone’s 2014 Long-Term Incentive Plan, as amended (the “2014 Plan”), to certain employees of Bold. Each EEHUnit, together with one share of Class B Common Stock, are convertible into one share of Class A Common Stock. The Bold Transaction was recorded in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic805, Business Combinations, and is consolidated in these financial statements in accordance with FASB ASC Topic 810, Consolidation, which requires therecording of a noncontrolling interest component of net income (loss), as well as a noncontrolling interest component within equity, including changes toadditional paid-in capital to reflect the noncontrolling interest within equity in the Consolidated Balance Sheet as of December 31, 2018 at thenoncontrolling interest’s respective membership interest in EEH.Note 2. – Summary of Significant Accounting PoliciesPrinciples of ConsolidationF-8Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

All intercompany accounts and transactions, including revenues and expenses, are eliminated inconsolidation.Use of EstimatesThe preparation of the Company’s consolidated financial statements in conformity with GAAP requires the Company’s management to make estimates andassumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities, if any, at the date of the consolidatedfinancial 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 our estimates. All reserve data included in theseConsolidated Financial Statements are based on estimates. Reservoir engineering is a subjective process of estimating underground accumulations of crudeoil, natural gas and natural gas liquids. There are numerous uncertainties inherent in estimating quantities of proved crude oil, natural gas and natural gasliquids reserves. The accuracy of any reserve estimate is a function of the quality of available data and of engineering and geological interpretation andjudgment. 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, assetretirement obligations, valuation allowances for deferred income tax assets, and valuation of derivative instruments. Management evaluates estimates andassumptions 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 19. Supplemental Information onOil and Gas Exploration and Production Activities (Unaudited).Accounts ReceivableAccounts receivable include amounts due from crude oil, natural gas, and natural gas liquids purchasers, other operators for which the Company holds aninterest, and from non-operating working interest owners. Accrued crude oil, natural gas, and natural gas liquids sales from purchasers and operators consist ofaccrued revenues due under normal trade terms, generally requiring payment within 60 days of production.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 ofall material trade receivables and other receivables to determine their collectability. Allowance for uncollectible accounts receivable was $0.1 million and$0.1 million at December 31, 2018 and 2017, respectively. Derivative InstrumentsThe Company utilizes derivative instruments in order to manage exposure to commodity price risk associated with future oil and natural gas production. TheCompany recognizes all derivatives as either assets or liabilities, measured at fair value, and recognizes changes in the fair value of derivatives in currentearnings. 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 arealso recognized in Gain (loss) on derivative contracts, net in the Consolidated Statements of Operations.Oil and Natural Gas PropertiesThe method of accounting for oil and natural gas properties determines what costs are capitalized and how these costs are ultimately matched with revenuesand expenses. The Company uses the successful efforts method of accounting for oil and natural gas properties. For more information see Note 7. Oil andNatural Gas Properties.GoodwillGoodwill represents the excess of the purchase price of assets acquired over the fair value of those assets and is tested for impairment annually, or morefrequently if events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable. Such test includes an assessment ofqualitative and quantitative factors. There were no impairments to Goodwill recorded in the years ended December 31, 2018 and 2017, respectfully. Forfurther discussion, see Note 8. Goodwill.Noncontrolling InterestF-9Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results.EARTHSTONE ENERGY, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)Noncontrolling Interest represents third-party equity ownership of EEH and is presented as a component of equity in the Consolidated Balance Sheet as ofDecember 31, 2018 and 2017, as well as an adjustment to Net income in the Consolidated Statement of Operations for the years ended December 31, 2018and 2017. As of December 31, 2018, Earthstone and Lynden US owned a 44.7% membership interest in EEH while Bold Holdings, the noncontrolling thirdparty, owned the remaining 55.3%. See further discussion in Note 9. Noncontrolling Interest.Segment ReportingOperating segments are components of an enterprise that (i) engage in activities from which it may earn revenues and incur expenses (ii) for which separateoperational financial information is available and is regularly evaluated by the chief operating decision maker for the purpose of allocating resources andassessing performance.Based on our organization and management, we have only one reportable operating segment, which is oil and natural gas exploration and production. Comprehensive IncomeThe Company has no elements of comprehensive income other than net income.Asset Retirement ObligationsAsset retirement obligations associated with the retirement of long-lived assets are recognized as liabilities with an increase to the carrying amounts of therelated 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. Assetretirement obligations are recorded at estimated fair value, measured by reference to the expected future cash outflows required to satisfy the retirementobligations discounted at the Company’s credit-adjusted risk-free interest rate. Accretion expense is recognized over time as the discounted liabilities areaccreted to their expected settlement value. If estimated future costs of asset retirement obligations change, an adjustment is recorded to both the assetretirement 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 CombinationsThe Company accounts for its acquisitions of oil and gas properties not commonly controlled in accordance with FASB ASC Topic 805, BusinessCombinations, which, among other things, requires the Company to determine if an asset or a business has been acquired. If the Company determines anasset(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 Companydetermines 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 RecognitionRevenues for the sale of oil, natural gas and natural gas liquids are recognized when the recognition criteria of ASC 606 “Revenue from Contracts withCustomers,” are met, which generally occurs as the product is delivered to customers’ custody transfer points and collectability is reasonably assured. TheCompany fulfills its performance obligations under its customer contracts through daily delivery of oil, natural gas and natural gas liquids and revenues arerecorded on a monthly basis and the Company receives payment from one to three months after delivery. The prices received for oil, natural gas and naturalgas liquids sales under the Company's contracts are generally derived from stated market prices which are then adjusted to reflect deductions includingtransportation, fractionation and processing. As a result, revenues from the sale of oil, natural gas and natural gas liquids will decrease if market pricesdecline. The sales of oil, natural gas and natural gas liquids as presented on the Consolidated Statements of Operations represent the Company’s share ofrevenues net of royalties and excluding revenue interests owned by others. When selling oil, natural gas and natural gas liquids on behalf of royalty ownersor 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 andnatural gas sales are unavailable for a given reporting period because of timing or information not received from third parties, the expected sales volumes andprices for those properties are estimated and recorded. The Company follows the sales method of accounting for gas imbalances. The Company had nosignificant gas imbalances as of December 31, 2018 or 2017.Concentration of Credit RiskCredit risk represents the actual or perceived financial loss that the Company would record if its purchasers, operators, or counterparties failed to performpursuant to contractual terms.F-10Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results.EARTHSTONE ENERGY, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)The purchasers of the Company’s oil, natural gas, and natural gas liquids production consist primarily of independent marketers, major oil and natural gascompanies and natural gas pipeline companies. Historically, the Company has not experienced any significant losses from uncollectible accounts. In 2018,three purchasers accounted for 27%, 11% and 10%, respectively, of the Company’s oil, natural gas, and natural gas liquids revenues. In 2017, threepurchasers accounted for 18%, 14% and 14%, respectively, of the Company’s oil, natural gas, and natural gas liquids revenues. No other purchaser accountedfor 10% or more of the Company’s oil, natural gas, and natural gas liquids revenues during 2018 and 2017. Additionally, at December 31, 2018, fivepurchasers accounted for 22%, 17%, 13%, 11% and 11%, respectively, of the Company’s oil, natural gas and natural gas liquids receivables. AtDecember 31, 2017, three purchasers accounted for 20%, 13% and 12%, respectively, of the Company’s oil, 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, 2018 and 2017.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, andNGLs to the purchaser, collects the cash, and distributes the cash to the Company. In 2018, no operator distributed 10% or more of the Company's oil, naturalgas and natural gas liquids revenues. In 2017, one operator distributed 10% of the Company’s oil, natural gas and natural gas liquids revenues. No otheroperator accounted for 10% or more of the Company’s oil, natural gas, and natural gas liquids revenues during 2017.The derivative instruments of the Company are with a small number of counterparties and, from time-to-time, may represent material assets in theConsolidated Balance Sheets. At December 31, 2018, the Company had a net derivative asset position of $62.6 million. At December 31, 2017, the Companyhad no 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 InsuranceCorporation (“FDIC”) insurance coverage and, as a result, there is a concentration of credit risk related to the amounts of deposit in excess of FDIC insurancecoverage.Stock-Based CompensationThe 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 restrictedstock units is based on the price of the Company’s 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 Simulationpricing model, which calculates multiple potential outcomes for an award and establishes fair value based on the most likely outcome, and is recognized overthe vesting period using the straight-line method. See Note 12. Stock-Based Compensation for further details.Income TaxesThe Company is a U.S. company operating primarily in Texas, as of December 31, 2018, as well as one foreign legal entity, Lynden Corp, which is aCanadian company. Consequently, the Company’s tax provision is based upon the tax laws and rates in effect in the applicable jurisdiction in which itsoperations 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 thesejurisdictions. This process involves estimating the actual current tax exposure together with assessing temporary differences resulting from differingtreatment of items, such as depreciation, amortization and certain accrued liabilities for tax and accounting purposes. The Company’s effective tax rate forfinancial statement purposes will continue to fluctuate from year to year as its operations are conducted in different taxing jurisdictions.Following the closing of the Bold Transaction, the Company continues to record an income tax provision consistent with its status as a corporation. TheCompany’s corporate structure requires the filing of two separate consolidated U.S. Federal income tax returns and one Canadian income tax return resultingfrom 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 offsetby tax attributes of Earthstone. Following the Bold Transaction, Earthstone and Lynden US record a tax provision, respectively, for their share of the bookincome 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 apartnership 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 BalanceSheets. 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 assetswill not be realized. At December 31, 2018 and 2017, the Company has recorded a valuation allowance for its deferred tax assets in the Consolidated BalanceSheets.

This accounting guidance clarifies the accounting for uncertainties inincome taxes by prescribing a minimum recognition threshold that a tax position is required to meet before being recognized in the consolidated financialstatements. It requires that the Company recognize in the consolidated financial statements the financial effects of a tax position, if that position is morelikely than not of being sustained upon examination, including resolution of any appeals or litigation processes, based upon the technical merits of theposition. It also provides guidance on measurement, classification, interest, penalties and disclosure. The Company’s tax positions related to its pass-throughstatus and state income tax liability, including deductibility of expenses, have been reviewed by the Company’s management and they believe thosepositions would more likely than not be sustained upon examination. Accordingly, the Company has not recorded an income tax liability for uncertain taxpositions at December 31, 2018 or 2017.On December 22, 2017, the United States enacted tax reform legislation commonly known as the Tax Cuts and Jobs Act (the “TCJA”), resulting in significantmodifications to existing law. Our consolidated financial statements for the year ended December 31, 2017, reflect certain effects of the TCJA, which includesthe federal corporate income tax rate reduction to 21%. Consistent with SEC Staff Accounting Bulletin ("SAB") No. 118, which provides for a measurementperiod of one year from the enactment date to finalize the accounting for effects of the TCJA, the Company provisionally recorded income tax expenseof $7.8 million related to the TCJA in 2017. In accordance with SEC guidance, provisional amounts may be refined as a result of additional guidance from,and interpretations by, U.S. regulatory and standard-setting bodies, and changes in assumptions. In the subsequent period, provisional amounts will beadjusted for the effects, if any, of interpretative guidance issued after December 31, 2017, by the U.S. Department of the Treasury. As of December 31, 2018,we have finalized the accounting for the enactment of the TCJA.Recently Issued Accounting StandardsRevenue Recognition – On January 1, 2018, the Company adopted the FASB Accounting Standards Update (“ASU”) for “Revenue from Contracts withCustomers,” which superseded the revenue recognition requirements in “Topic 605, Revenue Recognition,” using the modified retrospective method.Adoption of this standard did not have a significant impact on the consolidated statements of operations or cash flows. Additionally, the Companyimplemented processes to ensure new contracts are reviewed for the appropriate accounting treatment and generate the disclosures required under the newstandard.Statement of Cash Flows – In August 2016, the FASB issued updated guidance that clarifies how certain cash receipts and cash payments are presented in thestatement of cash flows. This update provides guidance on eight specific cash flow issues. The standards update is effective for interim and annual periodsbeginning after December 15, 2017 and should be applied retrospectively to all periods presented. Early adoption is permitted. The Company adopted thenew standard, as required, beginning with the first quarter of 2018, with no material impact on its Consolidated Financial Statements.Business Combinations – In January 2017, the FASB issued updated guidance that clarifies the definition of a business, which amends the guidance used inevaluating whether a set of acquired assets and activities represents a business. The guidance requires an entity to evaluate if substantially all of the fair valueof the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets andactivities is not considered a business. As a result, acquisition fees and expenses will be capitalized to the cost basis of the property acquired, and the tangibleand intangible components acquired will be recorded based on their relative fair values as of the acquisition date. The standard is effective for all publicbusiness entities for annual periods beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted forperiods for which financial statements have not yet been issued. The Company adopted the new standard, as required, beginning with the first quarter of2018, with no material impact on its Consolidated Financial Statements.Compensation – Stock Compensation – In May 2017, the FASB issued updated guidance that provides clarity about which changes to the terms orconditions of a share-based payment award require an entity to apply modification accounting. The update is effective for annual periods beginning afterDecember 15, 2017, and early adoption is permitted, including adoption in any interim period. The Company adopted the new standard, as required,beginning with the first quarter of 2018, with no material impact on its Consolidated Financial Statements.Leases – In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842): Amendments to the FASB Accounting Standards Codification (“ASU2016-02”). In January 2018, the FASB issued ASU No. 2018-01, Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842 (“ASU2018-01”). In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements (“ASU 2018-11”). Together these relatedamendments to GAAP represent ASC Topic 842, Leases (“ASC Topic 842”).ASU 2016-02 requires lessees to recognize lease assets and liabilities (with terms in excess of 12 months) on the balance sheet and disclose key quantitativeand qualitative information about leasing arrangements. The Company has substantially completed its current process of assessing existing contracts, as wellas future potential contracts, to determine the impact of its application on its consolidated financial statements and related disclosures. The evaluationprocess includes review of contracts for drilling rigs, office facilities, compression services, field vehicles and equipment, general corporate leased equipment,and other existingF-12Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The Company's evaluation process will not include review of its mineral leases asthey are outside the scope of ASC Topic 842.The Company plans to elect the package of practical expedients within ASU 2016-02 that allows an entity to not reassess, prior to the effective date, (i)whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases or (iii) initial direct costs for anyexisting leases, but does not plan to elect the hindsight practical expedient when determining the lease term of existing contracts at the effective date. Thenew standard also provides practical expedients for an entity’s ongoing accounting. The Company currently expects to elect the short-term lease recognitionexemption for all leases that qualify. The Company also currently expects to elect the practical expedient to not separate lease and non-lease components forthe majority of classes of underlying assets.Additionally, the Company also plans to elect the practical expedient under ASU 2018-01 and not evaluate existing or expired land easements notpreviously accounted for as leases prior to the effective date. The Company is working to complete its evaluation of the impact of ASC Topic 842 on itsfinancial statements, accounting policies and internal controls, including implementation of processes to capture, classify and account for leases within thescope of the new guidance and to provide the related disclosures.The Company will adopt this guidance as of January 1, 2019, the transition date, using the simplified transition method described in ASU 2018-11, in whicha cumulative-effect adjustment will be recognized in the opening balance of retained earnings in the period of adoption. At this time, the impact uponadoption of ASC Topic 842 is expected to result in recognition of an immaterial amount of additional operating liabilities, with corresponding right-of-useassets, on the Company’s Consolidated Balance Sheet for leases existing as of January 1, 2019, based on the present value of the remaining minimum rentalpayments under current leasing standards for existing operating leases. The adoption of this standard is not expected to have a material impact on theCompany’s Consolidated Statement of Income nor Consolidated Statement of Cash Flows.Intangibles – Goodwill and Other – In January 2017, the FASB issued updated guidance simplifying the test for goodwill impairment. The update eliminatesStep 2 of the goodwill impairment test. Instead, an entity should perform its annual or interim goodwill impairment test by comparing the fair value of areporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reportingunit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. An entity still has the optionto perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The update is effective for annual andinterim 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 is in the process of evaluating the impact of this guidance, if any, on its Consolidated Financial Statements.Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting – In June 2018, the FASB issuedupdated guidance simplifying the guidance on nonemployee share-based payments. The update is effective for annual and interim periods beginning afterDecember 15, 2018 and early adoption is permitted. The Company adopted the new standard, as required, beginning with the first quarter of 2018, with nomaterial impact on its Consolidated Financial Statements.Codification Improvements – In July 2018, the FASB issued an update which does not prescribe any new accounting guidance, but instead makes minorimprovements and clarifications of several different FASB Accounting Standards Codification areas based on comments and suggestions made by variousstakeholders. Certain updates are applicable immediately while others provide for a transition period to adopt as part of the next fiscal year beginning afterDecember 15, 2018. The Company adopted the new standard, as required, beginning with the first quarter of 2018, with no material impact on itsConsolidated Financial Statements.Fair Value Measurements – In August 2018, the FASB issued an update which modifies the disclosure requirements on fair value measurements in Topic820. The ASU is effective for fiscal years beginning after December 15, 2019 and early adoption is permitted. The Company is in the process of evaluatingthe impact of this update, if any, on its Consolidated Financial Statements.Note 3.

See Note 3. Acquisitions and Divestitures.Note 5. Fair Value MeasurementsFASB 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 betweenmarket participants at the measurement date. ASC Topic 820 provides a framework for measuring fair value, establishes a three-level hierarchy for fair valuemeasurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date and requires consideration of thecounterparty’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 activemarket is defined as a market where transactions for the financial instrument occur with sufficient frequency and volume to provide pricing information on anongoing 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 withmarket 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 underLevel 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. Whereavailable, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or inputs are notavailable, valuation models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which isdependent on the price transparency for the instruments or market and the instrument’s complexity. The Company reflects transfers between the three levelsat the beginning of the reporting period in which the availability of observable inputs no longer justifies classification in the original level. There were notransfers between fair value hierarchy levels for the year ended December 31, 2018.Fair Value on a Recurring BasisDerivative financial instruments are carried at fair value and measured on a recurring basis. The derivative financial instruments consist of swaps for crude oiland natural gas. The Company’s swaps are valued based on a discounted future cash flow model. The primary input for the model is published forwardcommodity price curves. The swaps are also designated as Level 2 within the valuation hierarchy.The fair values of commodity derivative instruments in an asset position include a measure of counterparty nonperformance risk, and the fair values ofcommodity derivative instruments in a liability position include a measure of the Company’s nonperformance risk. These measurements were not material tothe Consolidated Financial Statements.F-16Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The carrying amount of these instruments approximates fairvalue because of their short-term nature. The Company’s long-term debt obligation bears interest at floating market rates, therefore carrying amounts and fairvalue are approximately equal.Fair Value on a Nonrecurring BasisThe Company applies the provisions of the fair value measurement standard on a non-recurring basis to its non-financial assets and liabilities, including oiland 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 onlyin certain circumstances. Proved Oil and Natural Gas PropertiesProved oil and natural gas properties are reviewed for impairment on a nonrecurring basis. The impairment charge reduces the carrying values to theirestimated fair values. These fair value measurements are classified as Level 3 measurements and include many unobservable inputs. Fair value is calculated asthe estimated discounted future net cash flows attributable to the assets. The Company’s primary assumptions in preparing the estimated discounted futurenet 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 costsand 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 andNatural Gas Properties. GoodwillGoodwill represents the excess of the purchase price of assets acquired over the fair value of those assets and is tested for impairment annually, or morefrequently if events or changes in circumstances dictate that the fair value of goodwill may be less than its carrying amount. Such test includes an assessmentof qualitative and quantitative factors. See Note 8. Goodwill.Business CombinationsThe Company records the identifiable assets acquired and liabilities assumed at fair value at the date of acquisition on a nonrecurring basis. Fair value maybe estimated using comparable market data, a discounted cash flow method, or a combination of the two. In the discounted cash flow method, estimatedfuture cash flows are based on management’s expectations for the future and include estimates of future oil and natural gas production, commodity pricesbased on NYMEX commodity futures price strips as of the date of the estimate, operating and development costs, and a risk-adjusted discount rate. The futureoil and natural gas pricing used in the valuation is a Level 2 assumption. Significant Level 3 assumptions associated with the calculation of discounted cashflows used in the determination of fair value of the acquisition include the Company’s estimate operating and development costs,F-17Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The Company’s acquisitions are discussed in Note3. Acquisitions and Divestitures.Asset Retirement ObligationsThe asset retirement obligation estimates are derived from historical costs and management’s expectation of future cost environments; and therefore, theCompany has designated these liabilities as Level 3. The significant inputs to this fair value measurement include estimates of plugging, abandonment andremediation costs, well life, inflation and credit-adjusted risk-free rate. See Note 14. Asset Retirement Obligations for a reconciliation of the beginning andending balances of the liability for the Company’s asset retirement obligations.Note 6. Derivative Financial InstrumentsThe Company’s hedging activities consist of derivative instruments entered into in order to hedge against changes in oil and natural gas prices through theuse 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. Consistentwith its hedging policy, the Company has entered into a series of derivative instruments to hedge a significant portion of its expected oil and natural gasproduction through December 31, 2020. Typically, these derivative instruments require payments to (receipts from) counterparties based on specific indicesas required by the derivative agreements. Although not risk free, the Company believes these instruments reduce its exposure to oil and natural gas pricefluctuations 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 ConsolidatedFinancial Statements in accordance with FASB ASC Topic 815. The Company has accounted for these transactions using the mark-to-market accountingmethod. Generally, the Company incurs accounting losses on derivatives during periods where prices are rising and gains during periods where prices arefalling 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 AssociationMaster Agreement (“ISDA”), which provides for net settlement over the term of the contract. The ISDA is a standard contract that governs all derivativecontracts entered into between the Company and the respective counterparty. The ISDA allows for offsetting of amounts payable or receivable between theCompany and the counterparty, at the election of both parties, for transactions that occur on the same date and in the same currency.The following table sets forth the Company’s outstanding derivative contracts at December 31, 2018.

Exploration costs,including unsuccessful exploratory wells and geological and geophysical costs, are charged to operations as incurred. Upon sale or retirement of oil andnatural gas properties, the costs and related accumulated depreciation, depletion and amortization are eliminated from the accounts and the resulting gain orloss 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. Gainsand losses arising from the sale of properties are included in operating income (loss) 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, atthe field level, based on total proved reserves and proved developed reserves, respectively. Depletion expense for oil and natural gas producing property andrelated equipment was $47.1 million and $36.4 million for the years ended December 31, 2018 and 2017, respectively.Proved Oil and Natural Gas PropertiesProved oil and natural gas properties are reviewed for impairment on a nonrecurring basis. The impairment charge reduces the carrying values to theirestimated fair values. These fair value measurements are classified as Level 3 measurements and include many unobservable inputs. Fair value is calculated asthe estimated discounted future net cash flows attributable to the assets.

Undeveloped lease costs andunproved 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 onthe 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 Companyconsiders numerous factors including, but not limited to, current exploration and development plans, favorable or unfavorable exploration activity on theproperty being evaluated and/or adjacent properties, our geologists' evaluation of the property, and the remaining months in the lease term for the property.The Company had the following non-cash asset impairment charges to its oil and natural gas properties for the years ended December 31, 2018 and 2017 (inthousands): Years Ended December 31, 2018 2017Proved property$— $63,131Unproved property4,581 9,060Total$4,581 $72,191Accumulated impairments to proved and unproved oil and natural gas properties as of December 31, 2018 and 2017 were $121.1 million and $148.2 million,respectively.Note 8. GoodwillGoodwill represents the excess of the purchase price of assets acquired over the fair value of those assets and is tested for impairment annually, or morefrequently if events or changes in circumstances dictate that the carrying value of goodwill may not be recoverable. Such test includes an assessment ofqualitative and quantitative factors.The Company did not have any non-cash impairment charges to its goodwill for the years ended December 31, 2018 or 2017.Accumulated impairments to Goodwill as of December 31, 2018 and 2017 were $19.1 million.Note 9.

Organization and Basis of Presentation, Class A Common Stock and Class B Common Stock. At that time, all of Earthstone’s existing outstandingCommon Stock was automatically converted on a one-for-one basis into Class A Common Stock.Class A Common StockAt December 31, 2018 and 2017, there were 28,696,321 and 27,584,638 shares of Class A Common Stock issued and outstanding, respectively. During theyears ended December 31, 2018 and 2017, as a result of the vesting and settlement of restricted stock units under the 2014 Plan, Earthstone issued 681,585and 703,214 shares of Class A Common Stock, respectively, of which 169,893 and 61,055 shares of Class A Common Stock, respectively, were retained astreasury stock and canceled to satisfy the related employee income tax liability. On July 1, 2017, Earthstone retired and returned the 15,357 shares of treasurystock to authorized but unissued shares of Class A Common Stock. Additionally, on May 9, 2017, under the Bold Contribution Agreement, Earthstone issued150,000 shares of Class A Common Stock valued at approximately $2.0 million on that date.

Earthstonereceived net proceeds from this offering of $39.4 million, after deducting underwriters’ fees and offering expenses of $2.2 million. The net proceeds from theoffering were used to repay outstanding indebtedness under the EEH Credit Agreement, as described in Note 13. Long-Term Debt.Class B Common StockAt December 31, 2018 and 2017, there were 35,452,178 and 36,052,169 shares of Class B Common Stock issued and outstanding, respectively. Each share ofClass B Common Stock, together with one EEH Unit, is convertible into one share of Class A Common Stock. During the years ended December 31, 2018 and2017, 599,991 and 18,659 shares, respectively, of Class B Common Stock and EEH Units were exchanged for an equal number of shares of Class A CommonStock.

For additional information, see Note 3. Acquisitions and Divestitures. Note 12. Stock-Based CompensationRestricted Stock UnitsThe 2014 Plan allows, among other things, for the grant of restricted stock units (“RSUs”). On June 6, 2018, at the annual meeting of stockholders,Earthstone's stockholders approved an amendment and restatement of the 2014 Plan, including increasing the shares of Class A Common Stock that may beissued under the Plan by 600,000 shares, to a total of 6.4 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 havevoting rights prior to vesting and settlement. Prior to May 9, 2017, the Company determined the fair value of granted RSUs based on the market price of theCommon Stock on the date of the grant. Beginning on May 9, 2017, the Company began determining the fair value of granted RSUs based on the marketprice 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 vestingterm and is net of forfeitures, as incurred. Stock-based compensation is included in General and administrative expense in the Consolidated Statements ofOperations and is recorded with a corresponding increase in Additional paid-in capital within the Consolidated Balance Sheet.The table below summarizes unvested RSU activity for the year ended December 31, 2018: Shares Weighted-Average Grant DateFair ValueUnvested RSUs at December 31, 2017969,245 $9.89Granted567,500 $8.41Forfeited(44,165) $10.87Vested(681,585) $9.86Unvested RSUs at December 31, 2018810,995 $8.83During the year ended December 31, 2018, Earthstone granted 561,000 RSUs to employees and 6,500 RSUs to certain members of the Board with vestingperiods ranging from 12 to 36 months.

The total vesting date fair value of the RSUs that vested during 2018 and 2017 was $6.2 million and $8.3 million, respectively. As ofDecember 31, 2018, there was approximately $6.6 million of total unrecognized stock-based compensation expense related to unvested RSUs, which will beamortized over the remaining vesting periods. The weighted average remaining vesting period of the unrecognized compensation expense is 0.99 years.For the years ended December 31, 2018 and 2017, stock-based compensation related to RSUs was $6.1 million and $6.6 million, respectively.Performance UnitsOn February 28, 2018, the Board granted 252,500 performance units (“PSUs”) to certain named executive officers pursuant to the 2014 Plan. The PSUs arepayable in shares of Class A Common Stock based upon the achievement by the Company over a period commencing on February 28, 2018 and ending onFebruary 28, 2021 (the “Performance Period”) of performance criteria established by the Board. The number of shares of Class A Common Stock that may be issued will be determined by multiplying the number of PSUs granted by the Relative TotalShareholder Return ("TSR") Percentage (0% to 200%). The “Relative TSR Percentage” is the percentage, if any, achieved by attainment of a certainpredetermined range of targets for the Performance Period. Accordingly, the potential aggregate number of shares of Class A Common Stock issuable underthe outstanding PSU awards range from zero to 505,000.TSR for the Company and each of the peer companies is generally determined by dividing (A) the volume weighted average price of a share of stock for thetrading days during the thirty calendar days ending on and including the last calendar day of the Performance Period minus the volume weighted averageprice of a share of stock for the trading days during the thirty calendar days ending on and including the first day of the Performance Period plus cashdividends paid over the Performance Period by (B) the volume weighted average price of a share of stock for the trading days during the thirty calendar daysending on and including the first day of the Performance Period.As of December 31, 2018, there were 252,500 PSUs outstanding. There were no PSUs outstanding as of December 31, 2017. The unrecognized compensationexpense related to the PSU awards at December 31, 2018 was $2.5 million which will be amortized over the remaining vesting period. The weighted averageremaining vesting period of the unrecognized compensation expense is 1.12 years.The Company is accounting for this award as a market-based award which was valued utilizing the Monte Carlo Simulation pricing model, which calculatesmultiple potential outcomes for an award and establishes fair value based on the most likely outcome. Under the Monte Carlo Simulation pricing model,assuming a risk-free rate of 2.4% and volatilities ranging from 41.7% to 199.8%, the Company calculated the weighted average grant date fair value per PSUto be $13.75. For the year ended December 31, 2018, Stock-based compensation related to the PSUs was approximately $1.0 million. There was no Stock-based compensation related to the PSUs for the year ended December 31, 2017.Note 13.

The Plaintiff asserts that the directors negotiatedthe Bold Transaction to benefit EnCap and its affiliates, failed to obtain adequate consideration for the Earthstone shareholders who were not affiliated withEnCap or Earthstone management, did not follow an adequate process in negotiating and approving the Bold Transaction and made materially misleading orincomplete proxy disclosures in connection with the Bold Transaction. The suit seeks unspecified damages and purports to assert claims derivatively onbehalf 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 withprejudice. The Plaintiff filed an appeal with the Delaware Supreme Court. On February 6, 2019, the Delaware Supreme Court heard oral arguments from thePlaintiff and Defendants' counsel and has not yet issued an opinion. Earthstone and each of the other defendants believe the claims are entirely without meritand they intend to mount a vigorous defense. The ultimate outcome of this suit is uncertain, and while Earthstone is confident in its position, any potentialmonetary recovery or loss to Earthstone cannot be estimated at this time.On August 18, 2017, litigation captioned Trinity Royalty Partners, LP v. Bold Energy III LLC, et al. was filed with the 142nd Judicial District of the DistrictCourt in Midland County, Texas, asserting breach of contract and indemnity claims for alleged damages from loss of property relating to two oil and naturalgas wells in which Bold was the operator. Trinity Royalty Partners, LP (“Trinity”) claimed that Bold was required to indemnify Trinity under the terms of anassignment and a Participation and Joint Development Agreement between Bold and Trinity. Damages were claimed to include costs incurred in attemptingto repair and restore an oil and natural gas well and for the loss of future reserves attributable to both wells. On November 16, 2018 Trinity and Bold enteredinto a Confidential Settlement Agreement and Mutual Release whereby Trinity and Bold agreed to settle the lawsuit and release all claims and counterclaimsasserted by the parties. As a result, a $4.7 million expense has been recorded to Litigation settlement in the Consolidated Statements of Operations for theyear ended December 31, 2018.Note 17. Income TaxesOn December 22, 2017, President Trump signed into law the Tax Cuts and Jobs Act ("TCJA") that significantly changes the federal income taxation ofbusiness entities. The TCJA, among other things, reduces the corporate income tax rate to 21%, partially limits the deductibility of business interest expenseand net operating losses, imposes a one-time tax on unrepatriated earnings from certain foreign subsidiaries, taxes offshore earnings at reduced ratesregardless of whether they are repatriated and allows the immediate deduction of certain capital expenditures instead of deductions for depreciation expenseover time. Consistent with Staff Accounting Bulletin No. 118 issued by the SEC, which provides for a measurement period of one year from the enactmentdate to finalize the accounting for effects of the TCJA, the Company provisionally recorded income tax expense of $7.8 million related to the TCJA in thefourth quarter of 2017. As of December 31, 2018, the Company has finalized the accounting for the enactment of the TCJA.The Company’s corporate structure requires the filing of two separate consolidated U.S. Federal income tax returns and one Canadian income tax returnwhich include Lynden US, Earthstone, and Lynden Corp. As such, taxable income of Earthstone cannot be offset by tax attributes, including net operatinglosses, 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 incometax purposes, it is not subject to income tax at the federal level and only recognizes the Texas Margin Tax.F-26Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Deferred Tax Assets and LiabilitiesThe Company's deferred tax position reflects the net tax effects of the temporary differences between the carrying amounts of assets and liabilities forfinancial reporting purposes and the amounts used for income tax reporting. Significant components of the deferred tax assets and liabilities at December 31,2018 and 2017 are as follows (in thousands): December 31, 2018 2017Deferred noncurrent income tax assets (liabilities): Oil & gas properties$11,164 $2,998Basis difference in subsidiary obligation(2,211) (2,268)Investment in Partnerships(18,517) (111)Federal net operating loss carryforward12,940 12,986Net deferred noncurrent tax assets3,376 13,605Valuation allowance(16,865) (24,120)Net deferred tax liability$(13,489) $(10,515)As of December 31, 2018, the Company had a valuation allowance recorded against its deferred tax assets of $16.9 million which is in excess of its netdeferred noncurrent tax assets of $3.4 million, as presented above. The Company’s corporate organizational structure requires the filing of two separateconsolidated U.S. Federal corporate income tax returns, one separate U.S. Federal partnership income tax return and one Canadian income tax return. As aresult, tax attributes of one group cannot be offset by the tax attributes of another. At December 31, 2018, the deferred tax assets and liabilities related to thetwo U.S. Federal corporate income tax returns, one Canadian income tax return and one related to the Texas Margin Tax are a $13.1 million deferred tax asset,a $9.6 million deferred tax liability, a $3.8 million deferred tax asset and a $3.9 million deferred tax liability, respectively, before considering the valuationallowance of $16.9 million.As of December 31, 2017, the Company had a valuation allowance recorded against its deferred tax assets of $24.1 million which is in excess of its Netdeferred noncurrent tax assets of $13.6 million, as presented above. The Company’s corporate organizational structure requires the filing of two separateconsolidated U.S. Federal income tax returns, one separate U.S. Federal partnership income tax return and one Canadian income tax return. As a result, taxattributes of one group cannot be offset by the tax attributes of another. At December 31, 2017, 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 $20.5 million deferred tax asset, a $7.7 million deferredtax liability, a $3.6 million deferred tax asset and a $2.8 million deferred tax liability, respectively, before considering the valuation allowance of $24.1million. As of December 31, 2018, the Company had estimated U.S. net operating loss carryforwards of $42.4 million, the first expiring in 2034 and the last in 2038,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 operatinglosses and other tax attributes could be subject to a significant limitation if the Company were to undergo an ownership change for the purposes of Section382 (“Sec 382”) of the Internal Revenue Code of 1986, as amended (the “Code”). The Company has an additional estimated U.S. net operating losscarryforward of $28.0 million limited by Sec 382 resulting from the Lynden Arrangement. The Company continues to evaluate the impact, if any, of potentialSec 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 adjustmentsof taxes due or adjustments of the NOL carryforwards that are available to offset future taxable income. Generally, the Company’s income tax years 2011through 2018 remain open and subject to examination by the Internal Revenue Service or state tax jurisdictions where it conducts operations. In certainjurisdictions, the Company operates through more than one legal entity, each of which may have different open years subject to examination.Uncertain Tax PositionsFASB ASC Topic 740, Income Taxes (“ASC 740”) prescribes a recognition threshold and a measurement attribute for the financial statement recognition andmeasurement 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 mustbe more-likely-than-not to be sustained upon examination by taxing authorities.

The Company’s practice is to recognize estimated interest and penalties, if any, related to potential underpayment of income taxes as acomponent of income tax expense in its Consolidated Statement of Operations. As of December 31, 2018, the Company did not have any accrued interest orpenalties associated with any uncertain tax liabilities.Note 18. Profit Sharing PlanThe 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 annuallimits established by the federal government. The Company makes matching contributions of 100% of employee contributions, not to exceed six percent ofthe employee’s annual eligible compensation. The Company’s matching contributions vest immediately. The Company’s contributions to the 401(k) Planfor the years ended December 31, 2018 and 2017 were $0.5 million and $0.3 million, respectively.Note 19. Supplemental Information On Oil And Gas Exploration And Production Activities (Unaudited)Costs Incurred Related to Oil and Gas ActivitiesCapitalized costs include the cost of properties, equipment, and facilities for oil and natural gas producing activities. Capitalized costs for proved propertiesinclude costs for oil and natural gas leaseholds where proved reserves have been identified, development wells, and related equipment and facilities,including development wells in progress. Capitalized costs for unproved properties include costs for acquiring oil and natural gas leaseholds where noproved reserves have been identified, including costs of exploratory wells that are in the process of drilling or in active completion, and costs of exploratorywells suspended or waiting on completion.The Company’s oil and natural gas activities for 2018 and 2017 were entirely within the United States of America. Costs incurred in oil and natural gasproducing activities were as follows (in thousands): Years Ended December 31, 2018 2017Acquisition cost (1): Proved$41,569 $315,376Unproved31,268 245,589Exploration costs: Exploratory drilling— —Geological and geophysical630 1Development costs153,161 77,876Total additions$226,628 $638,842(1)Acquisition costs incurred during 2018 consisted primarily of an acreage trade in the Midland Basin and during 2017 consisted primarilyof the assets acquired in the Bold Transaction, both described in Note 3.

The datafor 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 existingreserve estimates may occur from time to time. Although every reasonable effort is made to ensure reserve estimates reported represent the most accurateassessments possible, the subjective decisions and variances in available data for various reservoirs make these estimates generally less precise than otherestimates 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 reasonablecertainty, to be recoverable in future years from known reservoirs under economic and operating conditions in effect when the estimates were made. Proveddeveloped reserves represent estimated quantities expected to be recovered through wells and equipment in place and under operating methods used whenthe estimates were made.The proved reserves estimates shown herein for the years ended December 31, 2018 and 2017 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 estimatesbe 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 estimatingquantities of proved reserves, including many factors beyond the Company’s control, such as commodity pricing. Reserve engineering is a subjective processof estimating underground accumulations of oil and natural gas that cannot be measured in an exact manner. The accuracy of any reserve estimate is afunction of the quality of available data and engineering and geological interpretation and judgement. 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, initialreserve estimates are often different from the quantities of oil and natural gas that are ultimately recovered. The meaningfulness of such estimates dependsprimarily on the accuracy of the assumptions upon which they were based. Except to the extent the Company acquires additional properties containingproved 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 forthe periods indicated. The oil prices as of December 31, 2018 and 2017 are based on the respective 12-month unweighted average of the first of the monthprices of the West Texas Intermediate (“WTI”) spot prices which equates to $65.56 per barrel and $51.34 per barrel, respectively. The natural gas prices as ofDecember 31, 2018 and 2017 are based on the respective 12-month unweighted average of the first of month prices of the Henry Hub spot price whichequates to $3.10 per MMBtu and $2.98 per MMBtu, respectively. Natural gas liquids are made up of ethane, propane, isobutane, normal butane and naturalgasoline, each of which have different uses and different pricing characteristics. The natural gas liquids prices used to value reserves as of December 31, 2018and 2017 averaged $28.81 per barrel and $22.59 per barrel, respectively. All prices are adjusted by lease or field for energy content, transportation fees, andmarket differentials. All prices are held constant in accordance with SEC guidelines.

In 2018, total extensions and discoveries of 16.2 MMBOE was a result of successful drilling results and wellperformance primarily related to the Midland Basin.•Sales of minerals in place. Sales of minerals in place totaled 6.6 MMBOE during 2018, which consisted of 4.7 MMBOE resulting from thedisposition of non-operated properties in the Midland Basin as part of an acreage trade and 1.9 MMBOE related to the disposition of non-operated Eagle Ford properties, both further described in Note 3. Acquisitions and Divestitures in the Notes to Consolidated FinancialStatements.•Purchases of minerals in place. In 2018, total purchases of minerals in place of 6.8 MMBOE were primarily attributable to developed non-producing wells and undeveloped acreage acquired in the Midland Basin as part of an acreage trade, as further described in Note 3.Acquisitions and Divestitures in the Notes to Consolidated Financial Statements.

In 2018, the upward revisions of prior reserves of 6.1 MMBOE consisted of improved PUD reserves of 5.8MMBOE with improved proved developed reserves of 0.3 MMBOE. PUD revisions are a result of our successful drilling efforts in theMidland Basin as well as improved commodity prices.Notable changes in proved reserves for the year ended December 31, 2017 included the following:•Extensions and discoveries. In 2017, total extensions and discoveries of 30,763 MBOE was a result of successful drilling results and wellperformance primarily related to the Midland Basin. The closing of the Bold Transaction in May 2017 which included primarily operatedacreage in the Midland Basin was a significant contributor to this.•Sales of minerals in place. Sales of minerals in place totaled 2,976 MBOE during 2017 and were primarily related to the disposition of theBakken properties, as further described in Note 3. Acquisitions and Divestitures in the Notes to Consolidated Financial Statements.•Purchases of minerals in place. In 2017, total purchases of minerals in place of 45,911 MBOE were primarily attributable to the BoldTransaction, whereby the Company acquired interests in 63 producing oil and natural gas wells, developed non-producing wells andundeveloped acreage in the Midland Basin, as further described in Note 3. Acquisitions and Divestitures in the Notes to ConsolidatedFinancial Statements. •Revision to previous estimates. In 2017, the downward revisions of prior reserves of 2,901 MBOE consisted of negative revisions to PUDreserves of 4,832 MBOE with improved proved developed reserves of 1,931 MBOE. PUD revisions are a result of (1) removal ofapproximately 2,011 MBOE of reserves due to delayed development plans of other operators in the Midland Basin that managementpreviously expected to be developed within five years, (2) reduction of 2,378 MBOE upon closing of the Bold Transaction and makingadjustments to development plans and PUD reserve assignments, and (3) non-participation in three Eagle Ford natural gas PUDs that wereexpected to develop 443 MBOE. Positive revisions are primarily a result of increased oil and natural gas prices during 2017.For wells classified as proved developed producing where sufficient production history existed, reserves were based on individual well performanceevaluation and production decline curve extrapolation techniques. For undeveloped locations and wells that lack sufficient production history, reserves werebased on analogy to producing wells within the same area exhibiting similar geologic and reservoir characteristics. Well spacing was determined fromdrainage patterns derived from a combination of performance-based recoveries and analogous producing wells for each area or field. PUD locations werelimited to areas of uniformly high-quality reservoir properties, between existing commercial producers where the reservoir can, with reasonable certainty, bejudged to be continuous with existing producers and contain economically producible oil and natural gas on the basis of available geoscience andengineering data. Changes in PUD reserves for the years ended December 31, 2018 and 2017 were as follows (in MBOE): Proved undeveloped reserves at December 31, 20162,690Conversions to developed(2,756)Extensions and discoveries27,977Sales of minerals in place(391)Purchases of minerals in place37,327Revision to previous estimates(4,832) Proved undeveloped reserves at December 31, 2017 (1)60,015Conversions to developed(4,419)Extensions and discoveries13,734Sales of minerals in place(4,702)Purchases of minerals in place4,735Revision to previous estimates5,838Proved undeveloped reserves at December 31, 2018 (2)75,201(1)Includes 34,029 MBOE attributable to noncontrolling interests.(2)Includes 41,560 MBOE attributable to noncontrolling interests.F-32Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

In the Company’s year-end 2017 plan to develop its PUDs within five years, the Company estimated that $51.9 million of capitalwould be expended in 2018 and that it would convert 4.3 MMBOE, which was consistent with the $55.4 million actually spent to convert 4.4 MMBOE todeveloped.Extensions and discoveries. Additionally, 13.7 MMBOE were added as extensions and discoveries due to successful drilling results on the Company’sacreage positions because of the wells it drilled. The increase was also supported by successful drilling results by other operators directly offsetting and inclose proximity to the Company’s acreage. All of these drilling results increased the confidence of the reservoir continuity and performance of the associatedreservoirs which increased the number of PUDs primarily in the Midland Basin.Sales of minerals in place. Sales of minerals in place totaled 4.7 MMBOE during 2018, which consisted of 3.7 MMBOE resulting from the disposition ofnon-operated properties in the Midland Basin as part of an acreage trade and 1.0 MMBOE related to the disposition of non-operated Eagle Ford properties,both further described in Note 3. Acquisitions and Divestitures in the Notes to Consolidated Financial Statements.Purchases of minerals in place. In 2018, purchases of minerals in place of 4.7 MMBOE were attributable to developed non-producing wells and undevelopedacreage acquired in the Midland Basin as part of an acreage trade, as further described in Note 3. Acquisitions and Divestitures in the Notes to ConsolidatedFinancial Statements.Revision to previous estimates. Revisions of 5.8 MMBOE were primarily due to our successful drilling efforts in the Midland Basin as well as improvedcommodity prices. 2017 Changes in Proved Undeveloped ReservesConversions to developed. In the Company’s year-end 2016 plan to develop its PUDs within five years, the Company estimated that $6.9 million of capitalwould be expended in 2017 and that it would convert 732 MBOE. Because of the improvement in commodity prices and the change in its development planfor 2017, the Company actually spent $8.5 million to convert 622 MBOE to developed. The Company’s plan changed in that it developed more oil PUDsand elected not to participate in natural gas PUDs which included the above mentioned 443 MBOE associated with the Eagle Ford non-participation. Thecapital to develop the Company’s oil PUDs was higher on a per unit basis than the natural gas PUDs however the margins are higher for oil PUDs. The oilPUDs further benefited the Company’s longer-term operated development plans. Since the Bold Transaction closed in May 2017, the associated capital planfor the properties acquired in the Bold Transaction during 2017 was not considered in the Company’s year-end 2016 report. The Company did however incur$63.4 million to convert 2,134 MBOE of purchased PUD reserves to Developed.Extensions and discoveries. Additionally, 27,977 MBOE were added as extensions and discoveries due to successful drilling results on the Company’sacreage positions because of the wells it drilled. The increase was also supported by successful drilling results by other operators directly offsetting and inclose proximity to the Company’s acreage. All of these drilling results increased the confidence of the reservoir continuity and performance of the associatedreservoirs which increased the number of PUDs primarily in the Midland Basin.Sales of minerals in place. Sales of minerals in place totaled 391 MBOE during 2017 and were primarily related to the disposition of the Bakken properties,as further described in Note 3. Acquisitions and Divestitures in the Notes to Consolidated Financial StatementsPurchases of minerals in place. During 2017, 37,327 MBOE were added to PUD reserves upon the closing of the Bold Transaction.Revision to previous estimates. Revisions of 4,832 MBOE were primarily due to (1) removal of approximately 2,011 MBOE of reserves due to delayeddevelopment plans of other operators in the Midland Basin that management previously expected to be developed within five years, (2) reduction of 2,378MBOE upon the closing of the Bold Transaction and making adjustments to development plans and PUD reserve assignments, and (3) non-participation inthree Eagle Ford natural gas PUDs that were expected to develop 443 MBOE. This non-participation has no impact on the Company’s ability to participate infuture wells in this acreage position.Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil and Natural Gas ReservesThe 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’sthird-party petroleum engineering firm. It can be used for some comparisons, but should not be the only method used to evaluate the Company or itsperformance. Further, the information in the following table may not represent realistic assessments of future cash flows, nor should the Standardized Measurebe viewed as representative of the current value of the Company.F-33Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results.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 therate 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, 2018 and 2017, as specified by the SEC, the prices for oil and natural gas used in this calculation were the unweighted 12-month average ofthe 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 GasReserves above. Future production costs include per-well overhead expenses allowed under joint operating agreements, abandonment costs (net of salvagevalue), and a non-cancelable fixed cost agreement to reserve pipeline capacity of 10,000 MMBtu per day for gathering and processing. Estimates of futureincome taxes are computed using current statutory income tax rates including consideration for estimated future statutory depletion and tax credits. Theresulting net cash flows are reduced to present value amounts by applying a 10% discount factor.The Standardized Measure is as follows (in thousands): December 31, 2018 2017Future cash inflows$4,479,757 $2,948,989Future production costs(1,013,131) (757,716)Future development costs(963,536) (677,093)Future income tax expense(90,570) (33,644)Future net cash flows2,412,520 1,480,53610% annual discount for estimated timing of cash flows(1,453,068) (887,836)Standardized measure of discounted future net cash flows (1)$959,452 $592,700(1)At December 31, 2018 and 2017, the portion of the standardized measure of discounted future net cash flows attributable to noncontrollinginterests was $530.2 million and $336.1 million, respectively.Changes in Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil and Natural Gas ReservesThe following is a summary of the changes in the Standardized Measure for the Company’s proved oil and natural gas reserves during each of the years in thethree-year period ended December 31, 2018 (in thousands): December 31, 2018 2017Beginning of year$592,700 $85,883Sales of oil and gas produced, net of production costs(136,143) (81,926)Sales of minerals in place(41,320) (15,553)Net changes in prices and production costs319,486 155,629Extensions, discoveries, and improved recoveries185,540 201,801Changes in income taxes, net(43,108) (5,941)Previously estimated development costs incurred during the period153,161 76,447Net changes in future development costs(316,765) (168,940)Purchases of minerals in place57,013 244,785Revisions of previous quantity estimates144,356 68,705Accretion of discount51,222 28,985Changes in timing of estimated cash flows and other(6,690) 2,825End of year (1)$959,452 $592,700(1)At December 31, 2018 and 2017, the portion of the standardized measure of discounted future net cash flows attributable to noncontrollinginterests was $530.2 million and $336.1 million, respectively.F-34Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

InterestsFebruary 11, 2019Page 2The discounted future net cash flow shown above should not be construed to represent an estimate of the fair market value of thereserves by Cawley, Gillespie & Associates, Inc. (“CG&A”).Future revenue is prior to deducting state production taxes and ad valorem taxes. Future net cash flow is after deducting thesetaxes, 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 isshown 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. The oil reserves include oil and condensate. Oil volumes and NGL volumes are expressed in barrels (42 U.S. gallons). Gasvolumes are expressed in thousands of standard cubic feet (Mcf) at contract temperature and pressure base.Hydrocarbon PricingAs requested for SEC purposes, the base oil and gas prices calculated for December 31, 2018 were $65.56/BBL and$3.100/MMBTU, respectively. As specified by the SEC, a company must use a 12-month average price, calculated as the unweightedarithmetic average of the first-day-of-the-month price for each month within the 12-month period prior to the end of the reportingperiod. The base oil price is based upon WTI-Cushing spot prices (Bloomberg) during 2018 and the base gas price is based upon HenryHub spot prices (Platts Gas Daily) during 2018. NGL prices were adjusted on a per-property basis and averaged 43.9% of the net oilprice 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, thenet realized prices for the SEC price case over the life of the proved properties was estimated to be $61.52 per barrel for oil, $2.16 perMCF for natural gas and $28.81 per barrel for NGL. All economic factors were held constant in accordance with SEC guidelines. Capital, Expenses and TaxesCapital expenditures, lease operating expenses and Ad Valorem tax values were forecast as provided by Earthstone. As youexplained, the capital costs were based on the most current estimates, lease operating expenses were based on the analysis of historicalactual expenses, operating overhead is included for non-operated properties and no credit or deduction is made for producing overheadpaid to the company by other owners of the operated properties. Capital costs and lease operating expenses were held constant inaccordance with SEC guidelines. Severance tax rates were applied at normal state percentages of oil and gas revenue. Severance Taxrates in certain instances, where authorized by taxing authorities, have severance tax abatements and were provided by your office andapplied when appropriate. SEC Conformance and RegulationsThe reserve classifications and the economic considerations used herein conform to the criteria of the SEC as defined in pages 3and 4 of the Appendix. The reserves and economics are predicated on regulatory agency classifications, rules, policies, laws, taxes androyalties currently in effect except as noted herein. Federal, state, and local laws and regulations, which are currently in effect and thatgovern the development and production of oil and natural gas, have been considered in the evaluation of proved reserves for thisreport. The possible effects of changes in legislation or other Federal or State restrictive actions which could affect the reserves andeconomics have not been considered. These possible changes could have an effect on the reserves and economics. However, we do notanticipate nor are we aware of any legislative changes or restrictive regulatory actions that may impact the recovery of reserves.Source: EARTHSTONE ENERGY INC, 10-K, March 12, 2019Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

InterestsFebruary 11, 2019Page 3This evaluation includes 182 proved undeveloped locations, all of which are commercial using required SEC pricing. Each ofthese commercial drilling locations proposed as part of Earthstone’s development plans conforms to the proved undeveloped standardsas 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 toensure this development plan will be fully executed.Reserve Estimation MethodsThe methods employed in estimating reserves are described on page 2 of the Appendix. Reserves for proved developedproducing wells were estimated using production performance methods for the vast majority of properties. Certain new producingproperties with very little production history were forecast using a combination of production performance and analogy to similarproduction, both of which are considered to provide a relatively high degree of accuracy.Non-producing reserve estimates, for both developed and undeveloped properties, were forecast using either volumetric oranalogy methods, or a combination of both. These methods provide a relatively high degree of accuracy for predicting proveddeveloped non-producing and proved undeveloped reserves. The assumptions, data, methods and procedures used herein areappropriate for the purpose served by this report.MiscellaneousAn on-site field inspection of the properties has not been performed nor has the mechanical operation or condition of the wellsand their related facilities been examined, nor have the wells been tested by Cawley, Gillespie & Associates, Inc. Possibleenvironmental liability related to the properties has not been investigated nor considered. Further, the net cost of plugging and thesalvage value of equipment at abandonment have been included herein.The reserve estimates and forecasts were based upon interpretations of data furnished by Earthstone and available from ourfiles. Ownership information and economic factors such as liquid and gas prices, price differentials and expenses were furnished byEarthstone. To some extent, information from public records was used to check and/or supplement these data. The basic engineeringand geological data were utilized subject to third party reservations and qualifications. Nothing has come to our attention, however, thatwould cause us to believe that we are not justified in relying on such data. All estimates represent our best judgment based on the dataavailable 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 derived therefrom and the actual costincurred could be more or less than the estimated amounts.Cawley, Gillespie & Associates, Inc. is a Texas Registered Engineering Firm (F-693), made up of independent registeredprofessional engineers and geologists that have provided petroleum consulting services to the oil and gas industry for over 50 years.This evaluation was supervised by W. Todd Brooker, President at Cawley, Gillespie & Associates, Inc. and a State of Texas LicensedProfessional Engineer (License #83462). We do not own an interest in the properties or Earthstone Energy, Inc. and are not employedon a contingent basis.
