All statements, other than statements of historical fact included in this Quarterly Report on Form 10-Q, regarding our strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management are forward-looking statements. Words such as “may,” “assume,” “forecast,” “position,” “predict,” “strategy,” “expect,” “intend,” “plan,” “estimate,” “anticipate,” “believe,” “project,” “budget,” “potential,” or “continue,” and similar expressions are used to identify forward-looking statements, although not all forward-looking statements contain such identifying words. When considering these forward-looking statements, investors should keep in mind the risk factors and other cautionary statements in this Quarterly Report on Form 10-Q. These forward-looking statements are based on management’s current beliefs, based on currently available information, as to the outcome and timing of future events.

Table of Contents

We caution investors that these forward-looking statements are subject to all of the risks and uncertainties incidental to our business, most of which are difficult to predict and many of which are beyond our control. These risks include, but are not limited to, commodity price volatility, inflation, availability of drilling, completion, and production equipment and services, environmental risks, drilling and completion and other operating risks, marketing and transportation risks, regulatory changes, the uncertainty inherent in estimating natural gas, NGLs, and oil reserves and in projecting future rates of production, cash flows and access to capital, the timing of development expenditures, conflicts of interest among our stockholders, impacts of world health events ~~including~~(including the COVID-19 ~~pandemic, potential shut-ins of production due to lack of downstream demand or storage capacity,~~pandemic), cybersecurity risks and the other risks described or referenced under the heading ~~“Risk~~“Item 1A. Risk Factors” herein, including the risk factors set forth in our Annual Report on Form 10-K for the year ended December 31, ~~2019~~2020 (the ~~“2019~~“2020 Form 10-K”) ~~and in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020, each of~~, which is on file with the Securities and Exchange Commission (“SEC”).

Reserve engineering is a process of estimating underground accumulations of natural gas, NGLs, and oil that cannot be measured in an exact manner. The accuracy of any reserve estimate depends on the quality of available data, the interpretation of such data, and the price and cost assumptions made by reservoir engineers. In addition, the results of drilling, testing, and production activities, or changes in commodity prices, may justify revisions of estimates that were made previously. If significant, such revisions would change the schedule of any further production and development drilling. Accordingly, reserve estimates may differ significantly from the quantities of natural gas, NGLs, and oil that are ultimately recovered.

Should one or more of the risks or uncertainties described or referenced in this Quarterly Report on Form 10-Q occur, or should underlying assumptions prove incorrect, our actual results and plans could differ materially from those expressed in any forward-looking statements.

All forward-looking statements, expressed or implied, included in this Quarterly Report on Form 10-Q are expressly qualified in their entirety by this cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral forward-looking statements that we or persons acting on our behalf may issue.

Except as otherwise required by applicable law, we disclaim any duty to update any forward-looking statements to reflect events or circumstances after the date of this Quarterly Report on Form 10-Q.

ANTERO RESOURCES CORPORATION

Notes to Unaudited Condensed Consolidated Financial Statements

~~December 31, 2019 and September 30, 2020~~

(1) Organization

Antero Resources Corporation (individually referred to as “Antero”) and together with its consolidated subsidiaries ~~(collectively referred to as~~ “Antero Resources,” or the “Company,” ~~“we,” “us” or “our”~~) ~~are~~is engaged in the development, production, exploration ~~development,~~ and acquisition of natural gas, NGLs, and oil properties in the Appalachian Basin in West Virginia and Ohio. The Company targets large, repeatable resource plays where horizontal drilling and advanced fracture stimulation technologies provide the means to economically develop and produce natural gas, NGLs, and oil from unconventional formations. The Company’s corporate headquarters ~~are~~is located in Denver, Colorado.

(2) Summary of Significant Accounting Policies

(a)

Basis of Presentation

These unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) applicable to interim financial information and should be read in the context of the Company’s December 31, ~~2019~~2020 consolidated financial statements and notes thereto for a more complete understanding of the Company’s operations, financial position and accounting policies. The Company’s December 31, ~~2019~~2020 consolidated financial statements were included in Antero Resources’ ~~2019~~2020 Annual Report on Form 10-K, which was filed with the SEC.

These unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information, and, accordingly, do not include all of the information and footnotes required by GAAP for complete consolidated financial statements. In the opinion of management, these unaudited condensed consolidated financial statements include all adjustments (consisting of normal and recurring accruals) considered necessary to present fairly the Company’s financial position as of December 31, ~~2019~~2020 and September 30, ~~2020,~~2021 and its results of operations for the three and nine months ended September 30, ~~2019 and~~ 2020 and ~~its~~2021 and cash flows for the nine months ended September 30, ~~2019~~2020 and ~~2020.~~2021. The Company has no items of other comprehensive income or loss; therefore, its net income or loss is equal to its comprehensive income or loss. Operating results for the period ended September 30, ~~2020~~2021 are not necessarily indicative of the results that may be expected for the full year because of the impact of fluctuations in prices received for natural gas, NGLs, and oil, natural production declines, the uncertainty of exploration and development drilling results, fluctuations in the fair value of derivative instruments, the impacts of COVID-19 and other factors.

(b)

Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of Antero Resources Corporation, its wholly owned subsidiaries, ~~any entities in which the Company owns a controlling interest,~~ and its variable interest ~~entities~~entity (“~~VIEs”~~VIE”), Martica Holdings LLC, (“Martica”), for which the Company is the primary beneficiary.

Through March 12, 2019, Antero Midstream Partners LP (“Antero Midstream Partners”), a publicly traded limited partnership, was included in the consolidated financial statements of Antero. Prior to the Closing (defined in Note 3—Deconsolidation of Antero Midstream Partners LP to the unaudited condensed consolidated financial statements), the Company’s ownership of Antero Midstream Partners common units represented approximately a 53% limited partner interest in Antero Midstream Partners, and Antero Resources consolidated Antero Midstream Partners’ financial position and results of operations into its consolidated financial statements. The Transactions (defined in Note 3—Deconsolidation of Antero Midstream Partners LP to the unaudited condensed consolidated financial statements) resulted in the exchange of the limited partner interest Antero Resources owned in Antero Midstream Partners for common stock of Antero Midstream Corporation, par value $0.01 per share (the “Antero Midstream Corporation common stock”), representing an approximate 31% interest in Antero Midstream Corporation. As a result, Antero Resources’ controlling interest in Antero Midstream Partners was converted to an interest in Antero Midstream Corporation that provides significant influence, but not control, over Antero Midstream Corporation. Thus, effective March 13, 2019, Antero no longer consolidates Antero Midstream Partners in its consolidated financial statements and accounts for its interest in Antero Midstream Corporation using the equity method of accounting. See Note 3—Deconsolidation of Antero Midstream Partners LP to the unaudited condensed consolidated financial statements for further discussion on the Transactions.

For the three months and nine months ended September 30, 2020, the Company determined that Martica Holdings LLC (“Martica”) is a VIE for which Antero is the primary beneficiary. Therefore, Martica’s accounts are consolidated in the Company’s consolidated financial statements. Antero is the primary beneficiary of Martica based on its power to direct the activities that most

~~Notes to Unaudited Condensed Consolidated Financial Statements~~

~~December 31, 2019 and September 30, 2020~~

significantly impact Martica’s economic performance, and its obligation to absorb losses of, or right to receive benefits from, Martica that could be significant to Martica. In reaching such determination that Antero is the primary beneficiary of Martica, the Company considered the following:

●

~~Martica was formed to hold certain overriding royalty interests across the Company’s existing asset base;~~

●

~~substantially all of Martica’s revenues are derived from production from the Company’s natural gas, NGLs, and oil properties in the Appalachian Basin in West Virginia and Ohio;~~

●

~~Antero owns the Class B Units in Martica, which entitle Antero to receive distributions in respect of the Incremental Override (as defined in Note 4—Transactions); and~~

●

~~Antero provides accounting, administrative and other services to Martica under a Management Services Agreement.~~

~~All significant intercompany accounts and transactions have been eliminated in the Company’s unaudited condensed consolidated financial statements.~~ The noncontrolling interest in the Company’s unaudited condensed consolidated financial statements for the nine months ended September 30, 2019 represents the interests in Antero Midstream Partners that were owned by the public prior to the Transactions, and the incentive distribution rights in Antero Midstream Partners. The noncontrolling interestreflected in the Company’s unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2020 and 2021 represents the Company’s interest in Martica owned by third parties. See Note 4—3—Transactions ~~for more information on the sale of this noncontrolling interest. Martica is a discrete entity and the assets and credits of Martica are not available~~ to ~~satisfy the debts and obligations of the Company or its other subsidiaries.~~

Investments in entities for which the Company exercises significant influence, but not control, are accounted for under the equity method. The Company’s judgment regarding the level of influence over its equity investments includes considering key factors such as Antero’s ownership interest, representation on the board of directors and participation in the policy-making decisions of equity method investees. Such investments are included in Investment in unconsolidated affiliate on the Company’s unaudited condensed consolidated balance sheets. Income (loss) from investees that are accounted for under the equity method is included in Equity in earnings (loss) of unconsolidated affiliates on the Company’s unaudited condensed consolidated statements of operations and cash flows. When Antero records its proportionate share of net income or net loss, it is recorded in equity in earnings (loss) of unconsolidated affiliates in the statements of operations and the carrying value of that investment on the Company’s balance sheet. When a distribution is received, it is recorded as a reduction to the carrying value of that investment on the Company’s balance sheet. The Company’s equity in earnings of unconsolidated affiliates is adjusted for intercompany transactions and the basis differences recognized due to the difference between the cost of the equity investment in Antero ~~Midstream Corporation and the amount of underlying equity in the net assets of Antero Midstream Partners as of the date of deconsolidation.~~

The Company accounts for distributions received from equity method investees under the “nature of the distribution” approach. Under this approach, distributions received from equity method investees are classified on the basis of the nature of the activity or activities of the investee that generated the distribution as either a return on investment, which is classified as cash inflows from operating activities, or a return of investment, which is classified as cash inflows from investing activities.

~~(c)~~

~~Use of Estimates~~

~~The preparation of~~ the unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect revenues, expenses, assets, liabilities and the disclosure of contingent assets and liabilities. Changes in facts and circumstances or discovery of newfor more information ~~may result in revised estimates, and actual results could differ from those estimates.~~

~~The Company’s unaudited condensed consolidated financial statements are based~~ on a number of significant estimates, including estimates of natural gas, NGLs, and oil reserve quantities, which are the basis for the calculation of depletion and impairment of oil and gas properties. Reserve estimates, by their nature, are inherently imprecise. Other items in the Company’s unaudited condensed consolidated financial statements that involve the use of significant estimates include derivative assets and liabilities, accrued revenue, deferred and current income taxes, equity-based compensation, asset retirement obligations, depreciation, amortization, and commitments and contingencies.

~~Risks and Uncertainties~~

The markets for natural gas, NGLs, and oil have, and continue to, experience significant price fluctuations. Price fluctuations can result from variations in weather, levels of production, availability of storage capacity and transportation to other regions of the country, the level of imports to and exports from the United States and various other factors. Increases or decreases in the prices the Company receives for its production could have a significant impact on the Company’s future results of operations and reserve quantities.Martica.

~~(e)~~(c)

Cash and Cash Equivalents

The Company considers all liquid investments purchased with an initial maturity of three months or less to be cash equivalents. The carrying value of cash and cash equivalents approximates fair value due to the short-term nature of these instruments. From time to time, the Company may be in the position of a “book overdraft” in which outstanding checks exceed cash and cash equivalents. The Company classifies book overdrafts in accounts payable and revenue distributions payable within its ~~unaudited~~ condensed consolidated balance sheets, and classifies the change in accounts ~~payable and revenue distributions~~ payable associated with book overdrafts as an operating activity within its unaudited condensed consolidated statements of cash flows. As of December 31, ~~2019,~~2020, the book ~~overdraft~~overdrafts included within accounts payable and revenue distributions payable ~~was $7~~were $11 million and ~~$18~~$15 million, respectively. As of September 30, ~~2020,~~2021, the book ~~overdraft~~overdrafts included within accounts payable and revenue distributions payable ~~was $8~~were $37 million and ~~$13~~$31 million, respectively.

~~(f)~~

~~Oil and Gas Properties~~

The Company accounts for its natural gas, NGLs, and oil exploration and development activities under the successful efforts method of accounting. Under the successful efforts method, the costs incurred to acquire, drill, and complete productive wells, development wells, and undeveloped leases are capitalized. Oil and gas lease acquisition costs are also capitalized. Exploration costs, including personnel and other internal costs, geological and geophysical expenses, delay rentals for gas and oil leases, and costs associated with unsuccessful lease acquisitions are charged to expense as incurred. Exploratory drilling costs are initially capitalized, but charged to expense if the Company determines that the well does not contain reserves in commercially viable quantities. The Company reviews exploration costs related to wells-in-progress at the end of each quarter and makes a determination, based on known results of drilling at that time, whether the costs should continue to be capitalized pending further well testing and results, or charged to expense. The Company incurred 0 such charges to expense during the three and nine months ended September 30, 2020. During the nine months ended September 30, 2019, the Company recorded an impairment charge of $26 million for design and initial costs related to pads that are no longer planned to be placed into service. The sale of a partial interest in a proved property is accounted for as a cost recovery, and no gain or loss is recognized as long as this treatment does not significantly affect the units-of-production amortization rate. A gain or loss is recognized for all other sales of producing properties.

~~Unproved properties are assessed for impairment on a property-by-~~property basis, and any impairment in value is charged to expense. Impairment is assessed based on remaining lease terms, commodity price outlooks, future plans to develop acreage, drilling results and reservoir performance of wells in the area. Unproved properties and the related costs are transferred to proved properties when reserves are discovered on, or otherwise attributed to, the property. Proceeds from sales of partial interests in unproved properties are accounted for as a recovery of cost without recognition of any gain or loss until the cost has been recovered. For the three months ended September 30, 2019 and 2020, impairment of unproved properties was $160 million and $29 million, respectively. For the nine months ended September 30, 2019 and 2020, impairment of unproved properties was $347 million and $156 million, respectively.

The Company evaluates the carrying amount of its proved natural gas, NGLs, and oil properties for impairment on a geological reservoir basis whenever events or changes in circumstances indicate that a property’s carrying amount may not be recoverable. If the carrying amount exceeds the estimated undiscounted future cash flows, the Company would estimate the fair value of its properties and record an impairment expense for any excess of the carrying amount of the properties over the estimated fair value of the properties. Factors used to estimate fair value may include estimates of proved reserves, estimated future commodity prices, future production estimates, and anticipated capital expenditures, using a commensurate discount rate.

Because estimated undiscounted future net cash flows based on future commodity prices as of September 30, 2019 exceeded the carrying amount of our proved properties in the Marcellus Shale as of September 30, 2019, management did not further evaluate our Marcellus proved properties for impairment. However, the carrying amount of the Company’s proved properties in the Utica

~~Table of Contents~~

~~ANTERO RESOURCES CORPORATION~~

~~Notes to Unaudited Condensed Consolidated Financial Statements~~

~~December 31, 2019 and September 30, 2020~~

Shale exceeded the estimated undiscounted future cash flows based on future commodity prices as of September 30, 2019. The Company estimated the fair value of the Utica Shale assets based on sales of other properties, estimates of proved reserves, estimated future commodity prices and future production estimates. As a result, the Company recorded an impairment expense of $881 million related to proved properties in the Utica Shale during the three months ended September 30, 2019. The Company did not incur any impairment expenses related to proved properties in the Utica Shale for the nine months ended September 30, 2020. The Company did not record any impairment expenses associated with its proved properties in the Marcellus Shale during the nine months ended September 30, 2019 and 2020.

~~(g)~~

~~Derivative Financial Instruments~~

In order to manage its exposure to natural gas, NGLs, and oil price volatility, the Company enters into derivative transactions from time to time, which may include commodity swap agreements, basis swap agreements, collar agreements, and other similar agreements related to the price risk associated with the Company’s production. To the extent legal right of offset exists with a counterparty, the Company reports derivative assets and liabilities on a net basis. The Company has exposure to credit risk to the extent that the counterparty is unable to satisfy its settlement obligations. The Company actively monitors the creditworthiness of counterparties and assesses the impact, if any, on its derivative positions.

The Company records derivative instruments on the unaudited condensed consolidated balance sheets as either assets or liabilities measured at fair value and records changes in the fair value of derivatives in current earnings as they occur. Changes in the fair value of commodity derivatives, including gains or losses on settled derivatives, are classified as revenues on the Company’s unaudited condensed consolidated statements of operations. The Company’s derivatives have not been designated as hedges for accounting purposes.

~~(h)~~

~~Asset Retirement Obligations~~

~~The Company is obligated to dispose of certain long-~~lived assets upon their abandonment. The Company’s asset retirement obligations (“AROs”) relate primarily to its obligation to plug and abandon oil and gas wells at the end of their lives. AROs are recorded at estimated fair value, measured by reference to the expected future cash outflows required to satisfy the retirement obligations, which is then discounted at the Company’s credit-adjusted, risk-free interest rate. Revisions to estimated AROs often result from changes in retirement cost estimates or changes in the estimated timing of abandonment. The fair value of the liability is added to the carrying amount of the associated asset, and this additional carrying amount is depreciated over the life of the asset. The liability is accreted at the end of each period through charges to operating expense.

~~(i)~~

~~Deferred Revenue~~

Under the terms of the VPP (as defined below in Note 4—Transactions), the Company is obligated to deliver certain natural gas volumes from specified wells to an overriding royalty interest owner over the term of the arrangement. The Company has accounted for the VPP as a conveyance under Accounting Standard Codifications (“ASC”) Topic 932, ~~Extractive Industries—Oil and Gas~~ (“ASC 932”), which requires the net proceeds to be recognized as deferred revenue due to the Company’s future performance obligations. Deferred revenue is recognized as volumes are delivered using the units-of-production method over the term of the VPP in Amortization of deferred revenue on the Company’s unaudited condensed consolidated statements of operations. See Note 4—Transactions for further discussion of the VPP transaction.

~~(j)~~

~~Natural Gas, NGLs, and Oil Revenues~~

The Company’s revenues are primarily derived from the sale of natural gas and oil production, as well as the sale of NGLs that are extracted from our natural gas. Sales of natural gas, NGLs, and oil are recognized when we satisfy a performance obligation by transferring control of a product to a customer. Payment is generally received in the month following the sale.

Under the Company’s natural gas sales contracts, it delivers natural gas to the purchaser at an agreed upon delivery point. Natural gas is transported from the wellheads to delivery points specified under sales contracts. To deliver natural gas to these points, Antero Midstream ~~Corporation~~ or other third parties gather, compress, process and transport the Company’s natural gas. The Company maintains control of the natural gas during gathering, compression, processing, and transportation. The Company’s sales contracts provide that it receives a specific index price adjusted for pricing differentials. The Company transfers control of the product at the delivery point and recognizes revenue based on the contract price. The costs incurred to gather, compress, process and transport natural gas are recorded as Gathering, compression, processing and transportation expense.

~~Table of Contents~~

~~ANTERO RESOURCES CORPORATION~~

~~Notes to Unaudited Condensed Consolidated Financial Statements~~

~~December 31, 2019 and September 30, 2020~~

NGLs, which are extracted from natural gas through processing, are either sold by the Company directly or by the processor under processing contracts. For NGLs sold by the Company directly, the sales contracts primarily provide that the Company delivers the product to the purchaser at an agreed upon delivery point and that it receives a specific index price adjusted for pricing differentials. The Company transfers control of the product to the purchaser at the delivery point and recognizes revenue based on the contract price. The costs incurred to process and transport NGLs are recorded as Gathering, compression, processing, and transportation expense. For NGLs sold by the processor, the Company’s processing contracts provide that the Company transfers control to the processor at the tailgate of the processing plant and it recognizes revenue based on the price received from the processor.

Under the Company’s oil sales contracts, Antero Resources’ generally sells oil to purchasers and collects a contractually agreed upon index price, net of pricing differentials. The Company recognizes revenue based on the contract price when it transfers control of the product to a purchaser. When applicable, the costs incurred to transport oil to a purchaser are recorded as Gathering, compression, processing and transportation expense.

~~(k)~~

~~Marketing Revenues and Expenses~~

~~Marketing revenues are derived from activities to purchase and sell third-party natural gas and NGLs and to market excess firm transportation capacity to third~~ parties. The Company retains control of the purchased natural gas and NGLs prior to delivery to the purchaser. The Company has concluded that it is the principal in these arrangements and therefore, the Company recognizes revenue on a gross basis, with costs to purchase and transport natural gas and NGLs presented as marketing expenses. Contracts to sell third party gas and NGLs are generally subject to similar terms as contracts to sell the Company’s produced natural gas and NGLs. The Company satisfies performance obligations to the purchaser by transferring control of the product at the delivery point and recognizes revenue based on the contract price received from the purchaser. Fees generated from the sale of excess firm transportation marketed to third parties are included in Marketing revenue.

Marketing expenses include the cost of purchased third-party natural gas and NGLs. The Company classifies firm transportation costs related to capacity contracted for in advance of having sufficient production and infrastructure to fully utilize the capacity (excess capacity) as marketing expenses since it is marketing this excess capacity to third parties. Firm transportation for which the Company has sufficient production capacity (even though it may not use the transportation capacity because of alternative delivery points with more favorable pricing) is considered unutilized capacity and is charged to transportation expense.

~~(l)~~

~~Gathering, compression~~, ~~water handling and treatment revenue~~

Substantially all revenues from the gathering, compression, water handling and treatment operations were derived from transactions for services Antero Midstream Partners provided to our exploration and production operations through March 12, 2019 and were eliminated in consolidation. Effective March 13, 2019, Antero Midstream Partners is no longer consolidated in Antero’s results. See Note 3~~—Deconsolidation of Antero Midstream Partners LP to the consolidated~~ financial statements for further discussion on the Transactions and Note 18—Segment information to the consolidated financial statements for disclosures on the Company’s reportable segments. The portion of such fees shown in our consolidated financial statements prior to March 13, 2019 represent amounts charged to interest owners in Antero-operated wells, as well as fees charged to other third parties for water handling and treatment services provided by Antero Midstream Partners or usage of Antero Midstream Partners’ gathering and compression systems. For gathering and compression revenue, Antero Midstream Partners satisfied its performance obligations and recognized revenue when low pressure volumes were delivered to a compressor station, high pressure volumes were delivered to a processing plant or transmission pipeline, and compression volumes were delivered to a high pressure line. Revenue was recognized based on the per Mcf gathering or compression fee charged by Antero Midstream Partners in accordance with the gathering and compression agreement. For water handling and treatment revenue, Antero Midstream Partners satisfied its performance obligations and recognized revenue when the fresh water volumes were delivered to the hydration unit of a specified well pad and the wastewater volumes were delivered to its wastewater treatment facility. For services contracted through third-party providers, Antero Midstream Partners’ performance obligation was satisfied when the services performed by the third-party providers were completed. Revenue was recognized based on the per barrel fresh water delivery or wastewater treatment fee charged by Antero Midstream Partners in accordance with the water services agreement.

Through March 12, 2019, the results of Antero Midstream Partners were included in the unaudited consolidated financial statements of Antero. Effective March 13, 2019, the results of Antero Midstream Partners are no longer consolidated in Antero’s results; however, the Company’s segment disclosures include our equity method investment in Antero Midstream Corporation due to its significance to the Company’s operations. See Note 3—Deconsolidation of Antero Midstream Partners LP to the unaudited condensed consolidated financial statements for further discussion on the Transactions and Note 18—Segment Information to the unaudited condensed consolidated financial statements for disclosures on the Company’s reportable segments.

All of the Company’s assets are located in the United States and substantially all of its production revenues are attributable to customers located in the United States; however, some of the Company’s production revenues are attributable to customers who then transport the Company’s production to foreign countries for resale or consumption.

The Company includes restricted stock unit (“~~RSUs”~~RSU”) awards, performance share unit (“~~PSUs”~~PSU”) awards and stock options in the calculation of diluted weighted average shares outstanding based on the number of common shares that would be issuable if the end of the period was also the end of the performance period required for the vesting of the awards. The potential dilutive effect of the 2026 Convertible Notes is calculated using the (i) treasury stock method for the three and nine months ended September 30, 2020 as a result of the Company’s intent to settle the principal amount of such convertible notes in cash upon conversion during the nine months ended September 30, 2020, and (ii) if-converted method for the three and nine months ended September 30, 2021, as a result of the partial equitizations of the 2026 Convertible Notes during the nine months ended September 30, 2021. See Note 7—Long-Term Debt for further discussion on the equitization transactions. During periods in which the Company incurs a net loss, diluted weighted average shares outstanding are equal to basic weighted average shares outstanding because the ~~effect~~effects of all equity awards isand the 2026 Convertible Notes are anti-dilutive.

(e)	Income Taxes

The Company recognizes deferred tax assets and liabilities for temporary differences resulting from net operating loss carryforwards for income tax purposes and the differences between the financial statement and tax basis of assets and liabilities. The effect of changes in tax laws or tax rates is recognized in income during the period such changes are enacted. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion, or all, of the deferred tax assets will not be realized.

On April 9, 2021, West Virginia enacted new tax laws related to its apportionment and sourcing methodologies. The newly enacted laws are effective January 1, 2022 on a prospective basis and are expected to reduce the Company’s net income or loss that is apportioned to West Virginia. As a result of this tax law change, the Company’s net deferred income tax liability was reduced by $34

~~Treasury Share Retirement~~

The Company retires treasury shares acquired through share repurchases and returns those shares to the status of authorized but unissued. When treasury shares are retired, the Company’s policy is to allocate the excess of the repurchase price over the par value of shares acquired first, to additional paid-in capital, and then to accumulated earnings. The portion allocable to additional paid-in capital is determined by applying a percentage, determined by dividing the number of shares to be retired by the number of shares outstanding, to the balance of additional paid-in capital as of retirement.

Recently Issued Accounting ~~Standard~~Standards

OnConvertible Instruments

In August 5, 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which eliminates the cash conversion model in ~~ASC~~Accounting Standards Codification (“ASC”) 470-20, Debt with Conversion and Other Options, that require separate accounting for conversion features, ~~that is currently being applied to the 2026 Convertible Notes,~~ and instead, allows the debt instrument and conversion features to be accounted for as a single debt instrument. The new standard becomes effective for the Company on January 1, 2022, and early adoption is permitted. The Company is evaluating ~~its~~the transition method it plans to use for adoption ~~including~~on January 1, 2022. However, the ~~adoption date and transition method.~~Company has utilized the modified retrospective approach to quantify the expected impact of this standard on its financial statements.

Upon adoption of this new standard, the Company expects to reclassify ~~$62~~between $15 million and $30 million, net of deferred income taxes and equity issuance costs, to long-term debt and deferred income tax liability, as applicable, from stockholders’ ~~equity.~~equity, which amount is subject to adjustment for any conversions or other transactions until adoption of this new standard. Additionally, annual interest expense for the 2026 Convertible Notes will be based on an effective interest rate of 4.8% as compared to ~~11.7%~~15.1% for the three and nine months ended September 30, ~~2020 in the statement of operations and the weighted average diluted shares outstanding will increase from 0 as of September 30, 2020 under the treasury-stock method to 66~~ ~~million under the if-converted method.~~2021. The Company does not believe that adoption of the standard will impact its operational strategies or ~~growth~~development prospects.

Income Taxes

In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes. This ASU removes certain exceptions to the general principles in ASC 740, Income Taxes (“ASC 740”) and also simplifies portions of ASC 740 by clarifying and amending existing guidance. It is effective for interim and annual reporting periods after December 15, 2020. The Company adopted this ASU on January 1, 2021, and it did not have a material impact on the Company's unaudited condensed consolidated financial statements.

(3) ~~Deconsolidation of Antero Midstream Partners LP~~

On March 12, 2019, Antero Midstream GP LP and Antero Midstream Partners completed (the “Closing”) the transactions contemplated by the Simplification Agreement (the “Simplification Agreement”), dated as of October 9, 2018, by and among Antero Midstream GP LP, Antero Midstream Partners and certain of their affiliates, pursuant to which (i) Antero Midstream GP LP was converted from a limited partnership to a corporation under the laws of the State of Delaware and changed its name to Antero Midstream Corporation, and (ii) an indirect, wholly owned subsidiary of Antero Midstream Corporation was merged with and into Antero Midstream Partners, with Antero Midstream Partners surviving the merger as an indirect, wholly owned subsidiary of Antero Midstream Corporation (together, along with the other transactions contemplated by the Simplification Agreement, the “Transactions”). In connection with the Closing, Antero received $297 million in cash and 158.4 million shares of Antero Midstream Corporation common stock in consideration for 98,870,335 common units representing limited partnership interests in Antero Midstream Partners.

The Company recorded a gain on deconsolidation of $1.4 billion calculated as the sum of (i) the cash proceeds received, (ii) the fair value of the Antero Midstream Corporation common stock received at the Closing, and (iii) the elimination of the noncontrolling interest less the carrying amount of the investment in Antero Midstream ~~Partners. The fair value of Antero’s retained equity method investment on March 13, 2019 in Antero Midstream Corporation was~~ ~~$2.0~~ billion based on the market price of the shares received on March 12, 2019. See Note 6—Equity Method Investments to the unaudited condensed consolidated financial statements for further discussion on equity method investments.

Antero Midstream Partners’ results of operations are no longer consolidated in the Company’s unaudited consolidated statement of operations and comprehensive income (loss) beginning March 13, 2019. Because Antero ~~Midstream Partners does not meet the requirements of a discontinued operation, Antero Midstream~~ ~~Partners’ results of operations continue to be included in the Company’s consolidated unaudited statement of operations and comprehensive income (loss) through March 12, 2019.~~

On June 15, 2020, the Company announced the consummation of a transaction with an affiliate of Sixth Street Partners, LLC (“Sixth Street”) relating to certain overriding royalty interests across the Company’s existing asset base (the “ORRIs”). In connection with the transaction, the Company contributed the ORRIs to Martica and Sixth Street contributed $300 million in cash (subject to customary adjustments) and agreed to contribute up to an additional $102 million in cash if certain production thresholds attributable to the ORRIs are achieved in the third quarter of 2020 and first quarter of 2021. All cash contributed by Sixth Street at the initial closing was distributed to the Company. ~~As of September 30, 2020, the~~The Company ~~determined it~~ met the applicable production ~~threshold~~thresholds related to the third quarter of 2020 ~~whereby it became entitled to receive~~and first quarter of 2021 as of September 31, 2020 and March 31, 2021, respectively. The Company received a $51 million cash distribution ~~that will be paid in~~during each of the fourth quarter of ~~2020.~~2020 and the second quarter of 2021.

The ORRIs include an overriding royalty interest of 1.25% of the Company’s working interest in all of its proved operated developed properties in West Virginia and Ohio, subject to certain excluded wells (the “Initial PDP Override”), and an overriding royalty interest of 3.75% of the Company’s working interest in all of its undeveloped properties in West Virginia and Ohio (the “Development Override”). Wells turned to sales after April 1, 2020 and prior to the later of (a) the date on which the Company turns to sales 2.2 million lateral feet (net to the Company’s interest) of horizontal wells burdened by the Development Override and (b) the earlier of (i) April 1, 2023 and (ii) the date on which the Company turns to sales 3.82 million lateral feet (net to the Company’s interest) of horizontal wells are subject to the Development Override.

The ORRIs also include an additional overriding royalty interest of 2.00% of the Company’s working interest in the properties underlying the Initial PDP Override (the “Incremental Override”). The Incremental Override (or a portion thereof, as applicable) may be re-conveyed to the Company (at the Company’s election) if certain production targets attributable to the ORRIs are achieved through March 31, 2023. Any portion of the Incremental Override that may not be re-conveyed to the Company based on the Company failing to achieve such production volumes through March 31, 2023 will remain with Martica.

Notes to Unaudited Condensed Consolidated Financial Statements

Prior to Sixth Street achieving an internal rate of return of 13% and ~~1.5x~~1.5x cash-on-cash return (the “Hurdle”), Sixth Street will receive all distributions in respect of the Initial PDP Override and the Development Override, and the Company will receive all distributions in respect of the Incremental Override, unless certain production targets are not achieved, in which case Sixth Street will receive some or all of the distributions in respect of the Incremental Override. Following Sixth Street achieving the Hurdle, the Company will receive 85% of the distributions in respect of the ORRIs to which Sixth Street was entitled immediately prior to the Hurdle being achieved.

The conveyance of the ORRIs from the Company to Martica was accounted for as a transaction between entities under common control. As a result, the contributed ORRIs have been recorded by Martica at their historical cost.

(b)	Volumetric Production Payment Transaction

On August 10, 2020, the Company completed a volumetric production payment transaction and received net proceeds of approximately ~~$215~~$216 million (the "VPP"). In connection with the VPP, the Company entered into a purchase and sale agreement, together with a conveyance agreement and production and marketing agreement, with J.P. Morgan Ventures Energy Corporation ("JPM-VEC") to convey, effective July 1, 2020, an overriding royalty interest in dry gas producing properties in West Virginia (the "VPP Properties") equal to 136,589,000 MMBtu over the expected seven-year term of the VPP.

The Company has accounted for the VPP as a conveyance under ASC 932, Extractive Activities—Oil and Gas (“ASC 932”), and the net proceeds were ~~recognized~~recorded as deferred revenue in the condensed consolidated balance sheet as of ~~September 30, 2020.~~the transaction closing. Deferred revenue is recognized as volumes are delivered using the units-of-production method over the term of the VPP. Under the production and marketing agreement, Antero and its affiliates provide certain marketing services as JPM-VEC’s agent, and any income or expenses related to these services will be recorded as marketing revenue or marketing expenses ~~(as the case may be).~~as appropriate.

Contemporaneously with the VPP, ~~transaction,~~ the Company executed a call option related to the production volumes associated with its retained interest in the VPP properties, which is collateralized by a mortgage on the VPP properties. Additionally, the production and marketing agreement contains an embedded put option related to the production volumes for the Company’s

See Note 11—Derivative Instruments to the unaudited condensed consolidated financial statements for more information on the Company’s derivative instruments.

(c)	Drilling Partnership

On February 17, 2021, Antero Resources announced the formation of a drilling partnership with QL Capital Partners (“QL”), an affiliate of Quantum Energy Partners, for the Company’s 2021 through 2024 drilling program. Under the terms of the arrangement, each year in which QL participates represents an annual tranche, and QL will be conveyed a working interest in any wells spud by Antero Resources during such tranche year. For 2021, Antero Resources and QL agreed to a capital budget for such annual tranche, and for each subsequent year through 2024, Antero Resources will propose a capital budget and estimated internal rate of return (“IRR”) for all wells to be spud during such year and, subject to the mutual agreement of the parties that the estimated IRR for the year exceeds a specified return, QL will be obligated to participate in such tranche. Antero Resources develops and manages the drilling program associated with each tranche, including the selection of wells. Additionally, for each annual tranche in which QL participates, Antero Resources and QL will enter into an assignment, bill of sale and conveyance pursuant to which QL will be conveyed a proportionate working interest percentage in each well spud in that year, which conveyance will not be subject to any reversion.

Under the terms of the arrangement, QL will fund 20% of development capital for wells spud in 2021 and is expected to fund between 15% and 20% of development capital for wells spud from 2022 through 2024, which funding amounts represent QL’s proportionate working interest in such wells. Additionally, Antero Resources may receive a carry in the form of a one-time payment from QL for each annual tranche if the IRR for such tranche exceeds certain specified returns, which will be determined no earlier than December 31 following the end of each tranche year. Capital costs in excess of, and cost savings below, a specified percentage of budgeted amounts for each annual tranche will be for Antero Resources’ account. Subject to the preceding sentence, for any wells included in a tranche, QL is obligated and responsible for its working interest share of costs and liabilities, and is entitled to its working interest share of revenues, associated with such wells for the life of such wells. If Antero Resources presents a capital budget for an annual tranche with an estimated IRR equal to or exceeding a specified return that QL in good faith believes is less than such specified return and QL elects not to participate, Antero Resources will not be obligated to offer QL the opportunity to participate in subsequent annual tranches.

~~(b)Transaction Price Allocated to Remaining Performance Obligations~~

For the Company’s product sales that have a contract term greater than one year, the Company utilized the practical expedient in ASC 606, Revenue from Contracts with Customers (“ASC 606”), which does not require the disclosure of the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Under the Company’s product sales contracts, each unit of product delivered to the customer represents a separate performance obligation; therefore, future volumes are wholly unsatisfied and disclosure of the transaction price allocated to remaining performance obligations is not required. For the Company’s product sales that have a contract term of one year or less, the Company utilized the practical expedient in ASC 606, which does not require the disclosure of the transaction price allocated to remaining performance obligations if the performance obligation is part of a contract that has an original expected duration of one year or less.

(c)Contract Balances

Under the Company’s sales contracts, the Company invoices customers after ~~the Company’s~~its performance obligations have been satisfied, at which point payment is unconditional. Accordingly, the Company’s contracts do not give rise to contract assets or liabilities. AtAs of December 31, ~~2019~~2020 and September 30, ~~2020,~~2021, the Company’s receivables from contracts with customers were ~~$318~~$425 million and ~~$339~~$653 million, respectively.

Senior Secured Revolving Credit Facility

Antero Resources has a senior secured revolving credit facility ~~(the “Credit Facility”)~~ with a consortium of bank lenders. On October 26, 2021, Antero Resources entered into an amended and restated senior secured revolving credit facility. References in the notes to the condensed consolidated financial statements to the (i) “Prior Credit Facility” refers to the senior secured revolving credit facility in effect for periods before October 26, 2021, (ii) “New Credit Facility” refers to the senior secured revolving credit facility in effect on or after October 26, 2021 and (iii) “Credit Facility” refers to Prior Credit Facility and New Credit Facility, collectively. Borrowings under the Credit Facility are subject to borrowing base limitations based on the collateral value of Antero Resources’ assets and are subject to regular semi-annual redeterminations. ~~The~~As of September 30, 2021, the borrowing base under the Prior Credit Facility was ~~re-affirmed in October 2020 at~~ $2.85 billion and lender commitments ~~are~~were $2.64 billion.

The Credit Facility provides for interest only payments until maturity at which time all outstanding borrowings are due. Interest is payable at a variable rate based on (i) LIBOR or the prime rate, determined by Antero ~~Resources had~~Resources’ election at the time of borrowing, plus an ~~outstanding balance~~applicable margin rate under the Prior Credit Facility and (ii) SOFR or prime rate, determined by Antero Resources’ election at the time of ~~$552 million,~~borrowing, plus an applicable margin rate under the New Credit Facility.

Commitment fees on the unused portion of the Credit Facility are due quarterly at rates ranging from (i) 0.300% to 0.375% ~~(subject~~with respect to the Prior Credit Facility, determined with reference to borrowing base utilization and (ii) 0.375% to 0.500% with respect to the New Credit Facility, determined with reference to borrowing base utilization, both rates subject to certain ~~exceptions) of the unused portion~~exceptions based on ~~utilization.~~the leverage ratio then in effect. The New Credit Facility includes fall away covenants, lower interest rates and reduced collateral requirements that Antero Resources may elect if Antero Resources is assigned an Investment Grade Rating (as defined in the New Credit Facility).

upon the occurrence of certain specified corporate events as set forth in the indenture governing the 2026 Convertible Notes.

From and after May 1, 2026, noteholders may convert their 2026 Convertible Notes at any time at their election until the close of business on the second scheduled trading day immediately before the maturity date.

Upon conversion, Antero Resources may satisfy its conversion obligation by paying and/or delivering, as the case may be, cash, shares of Antero Resources’ common stock or a combination of cash and shares of Antero Resources’ common stock, at Antero Resources’ election, in the manner and subject to the terms and conditions provided in the indenture governing the 2026 Convertible Notes. ~~Antero Resources’ current intent is to settle the principle amount of the~~The 2026 Convertible Notes ~~in cash upon conversion.

The conversion rate is subject to adjustment under certain circumstances in accordance with the terms of the indenture governing the 2026 Convertible Notes. In addition, following certain corporate events, as described in the indenture governing the 2026 Convertible Notes, that occur prior to the maturity date, Antero Resources will increase the conversion rate for a holder who elects to convert its 2026 Convertible Notes in connection with such a corporate event.

If certain corporate events that constitute a Fundamental Change occur, then noteholders may require Antero Resources to repurchase their 2026 Convertible Notes at a cash repurchase price equal to the principal amount of the 2026 Convertible Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. The definition of Fundamental Change includes certain business combination transactions involving Antero Resources and certain de-listing events with respect to Antero Resources’ common stock.

Upon issuance, the Company separately accounted for the liability and equity components of the 2026 Convertible Notes. The liability component was recorded at the estimated fair value of a similar debt instrument without the conversion feature. The difference between the principal amount of the 2026 Convertible Notes and the estimated fair value of the liability component was recorded as a debt discount and will be amortized to interest expense, together with debt issuance costs, over the term of the 2026 Convertible Notes using the effective interest method, with an effective interest rate of ~~10.8%~~15.1% per annum. As of the issuance date, the fair value of the 2026 Convertible Notes was estimated at ~~$203~~$172 million, resulting in a debt discount at inception of ~~$85~~$116 million. The equity component, representing the value of the conversion option, was computed by deducting the fair value of the liability component from the initial proceeds of the 2026 Convertible Notes issuance. This equity component was recorded, net of deferred taxes and issuance costs, in additional paid-in capital within the ~~unaudited~~condensed consolidated balance sheet and statement of stockholders’ equity and will not be remeasured as long as it continues to meet the conditions for equity classification.

Transaction costs related to the 2026 Convertible Notes issuance were allocated to the liability and equity components based on their relative fair values. Issuance costs attributable to the liability component were recorded within debt issuance costs on the ~~unaudited~~condensed consolidated balance sheet and are amortized over the term of the 2026 Convertible Notes using the effective interest method. Issuance costs attributable to the equity component were recorded as a charge to additional paid-in capital within the ~~unaudited~~condensed consolidated balance sheet and statement of stockholders’ equity.

(b)	Performance Share Unit Awards

PSU Awards Based on Absolute Total Shareholder Return (“TSR”)

In April 2021, the Company granted PSU awards to certain of its executive officers that vest based on Antero Resources’ absolute TSR determined as of the last day of each of 3 one-year performance periods ending on April 15, 2022, April 15, 2023, and April 15, 2024, and 1 cumulative three-year performance period ending on April 15, 2024, in each case, subject to the executive officer’s continued employment through April 15, 2024. The number of shares of common stock that may ultimately be earned following the end of the cumulative three-year performance period with respect to the TSR PSUs ranges from 0 to 200% of the target number of TSR PSUs originally granted. Expense related to these PSUs is recognized on a graded-vested basis over the term of each performance period. Forfeitures are accounted for as they occur by reversing the expense previously recognized for awards that were forfeited during the period.

PSU Awards Based on Leverage Ratio

In April 2021, the Company granted PSUs to certain of its executive officers that vest based on the Company’s total debt less cash and cash equivalents divided by the Company’s Adjusted EBITDAX (as defined and described in Item 2 below under “Non-GAAP Financial Measures”) determined as of the last day of each of 3 one-year performance periods ending on December 31,

The number of shares of common stock that may ultimately be earned with respect to the Leverage Ratio PSUs ranges from 0 to 200% of the target number of Leverage Ratio PSUs originally granted. Expense related to the Leverage Ratio PSUs is recognized based on the number of shares of common stock that are expected to be issued at the end of each measurement period, and such expense is reversed if the likelihood of achieving the performance condition becomes improbable. As of September 30, 2021, the likelihood of achieving the performance conditions related to the Leverage Ratio PSUs was probable.

~~(12)~~ Derivative Instruments

The Company is exposed to certain risks relating to its ongoing business operations, and it uses derivative instruments to manage its commodity price risk. In addition, the Company periodically enters into contracts that contain embedded features that are required to be bifurcated and accounted for separately as derivatives.

~~(a)Commodity Derivative Positions~~

(a)	Commodity Derivative Positions

The Company periodically enters into natural gas, NGLs, and oil derivative contracts with counterparties to hedge the price risk associated with its production. These derivatives are not entered into for trading purposes. To the extent that changes occur in the market prices of natural gas, NGLs, and oil, the Company is exposed to market risk on these open contracts. This market risk exposure is generally offset by the change in market prices of natural gas, NGLs, and oil recognized upon the ultimate sale of the Company’s production.

The Company was party to various fixed price commodity swap contracts that settled during the three and nine months ended September 30, ~~2019~~2020 and ~~2020.~~2021. The Company enters into these swap contracts when management believes that favorable future sales prices for the Company’s production can be secured. Under these swap agreements, when actual commodity prices upon settlement exceed the fixed price provided by the swap contracts, the Company pays the difference to the counterparty. When actual commodity prices upon settlement are less than the contractually provided fixed price, the Company receives the difference from the counterparty. In addition, the Company has entered into basis swap contracts in order to hedge the difference between the New York Mercantile Exchange (“NYMEX”) index price and a local index price.

The Company also entered into NGL derivative contracts, which establish a contractual price for the settlement month as a fixed percentage of the West Texas Intermediate Crude Oil index (“WTI”) price for the settlement month. When the percentage of the contractual price is above the contracted percentage, the Company pays the difference to the counterparty. When it is below the contracted percentage, the Company receives the difference from the counterparty.

In addition, the Company has also entered into a call option agreement that gives the counterparty the right, but not the obligation, to enter into a fixed price swap agreement on a specified future date for a specific amount of production for a specified future period.

The Company’s derivative contracts have not been designated as hedges for accounting purposes; therefore, all gains and losses are recognized in the Company’s statements of operations.

~~(13)~~(12) Leases

The Company leases certain office space, processing plants, drilling rigs and completion services, gas gathering lines, compressor stations, and other office and field equipment. Leases with an initial term of 12 months or less are considered short-term and are not recorded on the balance sheet. Instead, the short-term leases are recognized in expense on a straight-line basis over the lease term.

Most leases include one or more options to renew, with renewal terms that can extend the lease from one to 20 years or more. The exercise of the lease renewal options ~~are~~is at the Company’s sole discretion. The depreciable lives of the leased assets are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise.

Certain of the Company’s lease agreements include minimum payments based on a percentage of produced volumes over contractual levels and others include rental payments adjusted periodically for inflation.

The Company considers all contracts that have assets specified in the contract, either explicitly or implicitly, that the Company has substantially all of the capacity of the asset, and has the right to obtain substantially all of the economic benefits of that asset, without the lessor’s ability to have a substantive right to substitute that asset, as leased assets. For any contract deemed to include a leased asset, that asset is capitalized on the balance sheet as a right-of-use asset and a corresponding lease liability is recorded at the present value of the known future minimum payments of the contract using a discount rate on the date of commencement. The leased asset classification is determined at the date of recording as either operating or financing, depending upon certain criteria of the contract.

The discount rate used for present value calculations is the discount rate implicit in the contract. If an implicit rate is not determinable, a collateralized incremental borrowing rate is used at the date of commencement. As new leases commence or previous leases are modified the discount rate used in the present value calculation is the current period applicable discount rate.

The Company has made an accounting policy election to adopt the practical expedient for combining lease and non-lease components on an asset class basis. This expedient allows the Company to combine non-lease components such as real estate taxes, insurance, maintenance, and other operating expenses associated with the leased premises with the lease component of a lease agreement on an asset class basis when the non-lease components of the agreement cannot be easily bifurcated from the lease payment. Currently, the Company is only applying this expedient to certain office space agreements.

(f)	Related Party Lease Disclosure

The Company has a gathering and compression agreement with Antero Midstream Corporation, whereby Antero Midstream Corporation receives a low-pressure gathering fee per Mcf, a high-pressure gathering fee per Mcf and a compression fee per Mcf, in each case subject to annual adjustments based on the consumer price index. If and to the extent the Company requests that Antero Midstream Corporation construct new high pressure lines and compressor stations, the gathering and compression agreement contains minimum volume commitments that require Antero Resources to utilize or pay for 75% of the high pressure gathering capacity and 70%~~, respectively,~~ of the compression capacity of the requested capacity of such new construction for 10 years. In December 2019, the Company and Antero Midstream Corporation agreed to extend the initial term of the gathering and compression agreement to 2038 and established a growth incentive fee program whereby low pressure gathering fees will be reduced from 2020 through 2023 to the extent the Company achieves certain volumetric targets at certain points during such time. Upon completion of the initial contract term, the gathering and compression agreement will continue in effect from year to year until such time as the agreement is terminated, effective upon an anniversary of the effective date of the agreement, by either the Company or Antero Midstream Corporation on or before the 180^th day prior to the anniversary of such effective date. The Company achieved the volumetric targets during each ~~quarter in~~of the ~~three~~first, second and ~~nine months ended September 30,~~third quarters of 2020, and Antero Midstream Corporation provided a rebate of $12 million ~~in each such quarter. Antero Midstream Corporation has provided rebates of~~and $36 million for ~~the nine months ended September 30, 2020.~~

~~For~~ the three and nine months ended September 30, ~~2019, gathering and compression fees paid by Antero related to this agreement were $171 million and $486~~ ~~million,~~2020, respectively. The Company did 0t achieve the volumetric target during either the first, second or third quarters of 2021.

For the three and nine months ended September 30, 2020, gathering and compression fees paid by Antero related to this agreement were ~~$181~~$181 million and $503 million, respectively. For the three and nine months ended September 30, 2021, gathering and compression fees paid by Antero related to this agreement were $178 million and $539 million, respectively.

The NOV alleges that combustion devices at these facilities did not meet applicable air permitting requirements. Separately, in June 2018, wethe Company received an information request from the EPA Region III pursuant to Section 114(a) of the Clean Air Act relating to the facilities that were inspected in September 2017 as well as additional Antero Resources facilities for the purpose of determining if the additional facilities have the same alleged compliance issues that were identified during the September 2017 inspections. Subsequently, the West Virginia Department of Environmental Protection (“WVDEP”) and the EPA Region V (covering Ohio facilities) each conducted its own inspections, and ~~we have~~the Company has separately received NOVs from WVDEP ~~alleging violations relating~~and the EPA Region V related to similar issues being investigated by the ~~EPA.

WGL

The Company and Washington Gas Light Company and WGL Midstream, Inc. (collectively, “WGL”) were involved in ~~a pricing dispute~~multiple contractual disputes involving firm gas sales contracts executed June 20, 2014 (the “Contracts”) that the Company began delivering gas under in January 2016. ~~From January 2016 through~~ ~~July 2017~~ and from December 2017 through January 2018, the aggregate daily gas volumes contracted for under the Contracts was 500,000 MMBtu/day, with the aggregate daily contracted volumes having increased to 600,000 MMBtu/day from August through November 2017. The Company invoicedIn late 2015, WGL ~~based on~~asserted that the natural gas index price specified in the Contracts ~~and WGL paid the Company based on that invoice price. However, WGL asserted that the index price~~ was no longer appropriate ~~under the Contracts~~ and ~~claimed that~~sought to invoke an ~~undefined~~ alternative index ~~was more appropriate for~~clause in the ~~delivery point of the gas. In July 2016, the matter~~Contracts. This dispute was referred to ~~arbitration by the Colorado district court.~~arbitration. In January 2017, the arbitration panel ruled in the Company’s ~~favor. As a result,~~favor and found that the natural gas index price ~~has remained as~~ specified in the Contracts and there will be no adjustments to the invoices that have been paid by WGL, nor will future invoices to WGL be adjusted based on the same claim rejected by the arbitration panel. The arbitration panel’s award was confirmed by the Colorado district court on April 14, 2017.should remain.

In March of 2017, WGL filed a ~~second legal proceeding~~lawsuit against the Company in Colorado district court ~~alleging breach of contract and seeking damages of more than $30 million. In this lawsuit, WGL claimed~~claiming that the Company breached ~~its~~ contractual obligations ~~under the Contracts~~ by failing to deliver “TCO pool” ~~gas. In subsequent filings, WGL explained that its claims were based on an alleged obligation that the Company must deliver~~ gas, to the Columbia IPP Pool (“IPP Pool”). WGL asserted this exact same issue in the arbitration and it was rejected by the arbitration panel. The arbitration panel specifically found that the Delivery Point under the Contracts was at a specific geographic point in Braxton County, West Virginia, not the IPP Pool. On August 24, 2017, the Colorado district court dismissed with prejudice WGL’s claims against the Company in its new lawsuit and found that the Company had not breached its Contracts with WGL by allegedly failing to deliver to the IPP Pool. The Court dismissed WGL’s lawsuit because WGL had not adequately pled a claim against Antero Resources for the alleged failure to deliver “TCO pool” gas under the Contracts. WGL has appealed this decision to the Colorado Courtultimately seeking damages of Appeals, and on October 11, 2018, the Colorado Court of Appeals reversed the Colorado district court’s decision finding that WGL had adequately pled a claim for relief and remanded the case back to the district court for further proceedings.

The Company is also actively engaged in pursuing cover damages against WGL based on WGL’s failure to take receipt of all of the agreed quantities of gas required under the Contracts. WGL’s failure to take the gas volumes specified in the Contracts is directly related to WGL’s lack of primary firm transportation rights at the Delivery Point. The failures by WGL to take the full contracted volumes of gas began in April 2017 and continued each month through December 2017 in varying quantities. In defense of its conduct, WGL asserted to the Company that their failure to receive gas is excused by (1) the Company’s failure to deliver gas to the IPP Pool or (2) alleged instances of Force Majeure under the Contracts. However, as stated above, the alleged obligation that the Company must deliver gas to the IPP Pool was already rejected by the arbitration panel. Further, the Contracts expressly prohibit a Force Majeure claim in circumstances in which the gas purchaser does not have primary firm transportation agreements in place to transport the purchased gas. In each instance thatmore than $40 million. Subsequently, after WGL failed to ~~receive the quantity~~take certain volumes of gas required under the Contracts, the

General and administrative expenses were allocated to the midstream segment based on the nature of the expenses and on a combination of the segments’ proportionate share of the Company’s consolidated property and equipment, capital expenditures, and labor costs, as applicable. General and administrative expenses related to the marketing segment are not allocated because they are immaterial. Other income, income taxes, and interest expense are primarily managed and evaluated on a consolidated basis. Intersegment sales were transacted at prices which approximate market.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of ~~Operations.~~Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited condensed consolidated financial statements and related notes included elsewhere in this Quarterly Report on Form 10-Q. The following discussion contains “forward-looking statements” that reflect our future plans, estimates, beliefs and expected performance. We caution that assumptions, expectations, projections, intentions, or beliefs about future events may, and often do, vary from actual results, and the differences can be material. Some of the key factors that could cause actual results to vary from our expectations include changes in natural gas, NGLs, and oil prices, the timing of planned capital expenditures, our ability to fund our development programs, uncertainties in estimating proved reserves and forecasting production results, operational factors affecting the commencement or maintenance of producing wells, the condition of the capital markets generally, as well as our ability to access them, impacts of world health events, including the COVID-19 pandemic, potential shut-ins of production due to lack of downstream demand or storage capacity, and uncertainties regarding environmental regulations or litigation and other legal or regulatory developments affecting our business, as well as those factors discussed below, all of which are difficult to predict. In light of these risks, uncertainties and assumptions, the forward-looking events discussed may not occur. See “Cautionary Statement Regarding Forward-Looking Statements.” Also, see the risk factors and other cautionary statements described under the heading “Item 1A. Risk Factors.” We do not undertake any obligation to publicly update any forward-looking statements except as otherwise required by applicable law.

In this section, references to “Antero,” the “Company,” “we,” “us,” and “our” refer to Antero Resources Corporation and its subsidiaries, unless otherwise indicated or the context otherwise requires.

Our Company

We are an independent oil and natural gas company engaged in the development, production, exploration ~~development~~ and ~~production~~acquisition of natural gas, NGLs, and oil properties located in the Appalachian Basin. We focus on unconventional reservoirs, which can generally be characterized as fractured shale formations. Our management team has worked together for many years and has a successful track record of reserve and production growth as well as significant expertise in unconventional resource plays. Our strategy is to leverage our team’s experience delineating and developing natural gas resource plays to profitably grow our reserves and production, primarily on our existing multi-year inventory of drilling locations.

We have assembled a portfolio of long-lived properties that are characterized by what we believe to be low geologic risk and repeatability. Our drilling opportunities are focused in the Marcellus Shale and Utica Shale of the Appalachian Basin. As of September 30, ~~2020,~~2021, we held approximately ~~522,000~~508,000 net acres of rich gas and dry gas properties located in the Appalachian Basin in West Virginia and Ohio. Our corporate headquarters are in Denver, Colorado.

~~We operate in the following industry segments: (i)~~ the exploration, development, and production of natural gas, NGLs, and oil; (ii) marketing of excess firm transportation capacity; and (iii) our equity method investment in Antero Midstream Corporation. All of our operations are conducted in the United States. As described below and elsewhere in this Quarterly Report on Form 10-Q, effective March 13, 2019, the results of Antero ~~Midstream Partners are no longer consolidated in Antero’s results.~~

~~2020~~2021 Developments and Highlights

COVID-19 Pandemic

In March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic. Governments ~~have~~ tried to slow the spread of the virus by imposing social distancing guidelines, travel restrictions and stay-at-home orders, among other actions, which ~~have~~ caused a significant decrease in activity in the global economy and the demand for oil and, to a lesser extent, natural gas and NGLs. Also in March 2020, Saudi Arabia and Russia failed to agree to cut production of oil along with the Organization of the Petroleum Exporting Countries (“OPEC”), and Saudi Arabia significantly reduced the price at which it sells oil and announced plans to increase production, which contributed to a sharp drop in the price of oil. While OPEC, Russia and other allied producers reached an agreement in April 2020 to reduce production, oil prices have remained low. The imbalance between the supply of and demand for oil, as well as the uncertainty around the extent and timing of an economic recovery, ~~have~~ caused extreme market volatility and a substantial adverse effect on commodity ~~prices.~~prices in 2020. As vaccines have become widely available, social distancing guidelines, travel restrictions and stay-at-home orders have eased, activity in the global economy has increased and demand for oil, natural gas and NGLs, and related commodity pricing, has improved. However, new variants of the virus could cause further commodity market volatility and resulting financial market instability, and these are variables beyond our control that may adversely impact our generation of funds from operating cash flows, distributions from unconsolidated affiliate, available borrowings under our Credit Facility (defined below in “—Capital Resources and Liquidity—Debt Agreements—Senior Secured Revolving Credit Facility”) and our ability to access the capital markets.

As a producer of natural gas, NGLs and oil, we are recognized as an essential business under various federal, state and local regulations related to the COVID-19 pandemic. WeAs such, we have continued to operate throughout the pandemic as permitted under these regulations while taking steps to protect the health and safety of our employees and contract workers. We have implemented protocols to reduce the risk of an outbreak within our field operations, and these protocols have not reduced production or efficiency in a significant manner. A substantial portion of our non-field level employees operated in remote work from home arrangements through September 30, 2021, and due to the rise of COVID-19 cases as a result of new variants of the virus, our plans to return to in-

Table of Contents

~~portion~~office arrangements during the third quarter of 2021 have been deferred in order to protect the health and safety of our ~~non-field level~~ employees ~~continue to operate in remote work from home arrangements,~~ and wecontract workers. We have been able to maintain a consistent level of effectiveness through these arrangements, including maintaining our day-to-day operations, our financial reporting systems and our internal control over financial reporting.

Our natural gas, NGLs and oil producing properties are located in the liquids-rich Appalachian Basin. Although the decline in oil prices has negatively impacted our oil revenue, oil sales represented approximately 4% of our total revenue for each of the nine months ended September 30, 2020 and the year ended December 31, 2019. While natural gas prices also declined during the first half of 2020, benchmark Henry Hub prices recovered during the third quarter and averaged $2.58/Mcf in September. Similarly, C3+ NGL prices also improved during the third quarter as gasoline demand increased, supporting prices for normal butane (nC4), isobutane (iC4), and pentane (C5), all of which are used for gasoline. The COVID-19 induced demand destruction on gasoline, which forced C5 prices below propane prices for much of April to under $0.40 per gallon, has since rebounded with benchmark C5 price in October in the range of $0.85 to $0.95 per gallon.

~~In addition, we~~We have hedged through fixed price contracts the sale of ~~1.3~~2.2 Bcf per day of natural gas at a weighted average price of ~~$2.84~~$2.78 per MMBtu for the remainder of ~~2020.~~2021. Our hedges cover a substantial majority of our expected natural gas production ~~in 2020.~~for the remainder of 2021. We also have fixed priced contracts for the sale of ~~10,315 barrels per day of propane at a weighted average price of $0.65 per gallon, 24,500 barrels per day of ethane at a weighted average price of $0.20 per gallon and 26,000~~3,000 barrels per day of oil at a weighted average price of ~~$55.63~~$55.16 per barrel for the remainder of ~~2020.~~2021. All of our hedges are financial hedges and do not have physical delivery requirements. As such, any decreases in anticipated production, ~~whether~~such as a result of decreased development activity, ~~shut-ins, or through transactions under our asset sale plan,~~ will not impact our ability to realize the benefits of ~~the~~our hedges.

Our natural gas and NGLs are primarily used in manufacturing, power generation and heating rather than transportation. While we have seen a decrease in the overall demand for these products, demand for natural gas and NGLs has not declined as much as demand for oil, and there has not been as substantial an oversupply of natural gas and NGLs as there has been of oil. Furthermore, the decrease in demand for oil has significantly reduced the number of rigs drilling for oil in the continental U.S. and, as a result, estimates of future gas supply associated with oil production have declined. Additionally, the restart of economic activity in Asia and Europe, coupled with lower LPG production from refineries in the U.S., Europe, and Asia during the second quarter, provided support for international LPG prices relative to oil. Further, reductions in OPEC+ and North American oil production and the associated NGL volumes are expected to have a supportive effect on propane and butane prices through the remainder of 2020 and into 2021.

During the third quarter of 2020, we shipped 54% of our total C3+ NGL net production on Mariner East 2 for export and realized a $0.04 per gallon premium to Mont Belvieu pricing on these volumes at Marcus Hook, PA. We sold the remaining 46% of C3+ NGL net production at a $0.12 per gallon discount to Mont Belvieu pricing at Hopedale, OH. We expect to sell at least 50% of our C3+ NGL full-year production in 2020 at Marcus Hook for export at a premium to Mont Belvieu.

Condensate differentials to WTI were approximately $15/Bbl during the third quarter. Pre-hedge oil realizations were negatively impacted during the second quarter and beginning of the third quarter as Antero sold volumes at a material discount to WTI in order to keep from shutting in production volumes. This period of weak condensate demand driven by the pandemic coincided with an active well completion period for Antero that brought on large condensate volumes. The negative impact from wider oil differentials was more than offset by the benefit of maintaining full natural gas and NGL volumes through this period. Antero expects its full year 2020 realized oil price differential to be at the high end of the $10.00/Bbl to $12.00/Bbl range, as the differential normalizes during the fourth quarter of 2020.

Our supply chain ~~also~~ has not experienced any significant interruptions. The industry continues to experience storage capacity constraints for oil and certain NGL products, and we may become subject to those constraints if we are not able to sell our production or certain components thereof, or enter into additional storage arrangements. The lack of a market or available storage for any one NGL product or oil could result in our having to delay or discontinue well completions and commercial production or shut in production for other products because we cannot curtail the production of individual products in a meaningful way without reducing production of other products. Potential impacts of these constraints may include partial shut-in of production, although we are not able to determine the extent of shut-ins or for how long they may last. However, because some of our wells produce rich gas, which is processed, and some produce dry gas, which does not require processing, we can change the mix of products that we produce and wells that we complete to adjust our production to address takeaway capacity constraints for certain products. For example, we can shut-in rich gas wells and still produce from our dry gas wells if processing or storage capacity of NGL products becomes further limited or constrained. ~~Also, prior~~Prior to the COVID-19 pandemic, we had developed a diverse set of buyers and destinations, as well as in-field and off-site storage capacity for our condensate ~~volumes, and such capacity is still largely available to us.~~

~~During the third quarter of 2020, condensate differentials to WTI were notably wider as~~volumes. As a result of ~~COVID-19 demand destruction at both~~ the ~~Appalachia regional level and national level. To protect against production curtailments and shut-ins due to~~

~~insufficient storage capacity, Antero~~pandemic, we have expanded ~~its~~our customer base and ~~its~~our condensate storage capacity within the basin. In addition, Antero entered into transactions that required buyers to transport product to more distant markets and storage, which coincided with substantially weakened crack spreads for refined products. To date, Antero has not shut in or curtailed any production from its assets as a resultAppalachian Basin.

As of ~~COVID-19 demand issues and does not expect to shut in any volumes during 2020.~~

~~In addition, as discussed~~September 30, 2021, we had $98 million of borrowings under our Prior Credit Facility (defined below in “—~~2020~~ Capital ~~Budget~~Resources and ~~Capital Spending,” in April 2020,~~Liquidity—Debt Agreements—Senior Secured Revolving Credit Facility”) and had outstanding letters of credit of $742 million. On October 26, 2021, we ~~announced~~ amended our Prior Credit Facility with a ~~34% reduction in our drilling~~borrowing base of $3.5 billion and completion capital budget for 2020. During the third quarter, our ongoing emphasis on completion efficiencies and drilling longer laterals resulted in material improvements in well costs. Well costs average $640 per lateral foot during the third quarter, benefiting from these efficiency improvements and lateral lengths that averaged over 15,000 feet. Well costs were $675 per foot when normalized for a 12,000 foot lateral length. We expect well costs to average $675 per foot during the fourth quarterlender commitments of 2020, based on a 12,000 foot lateral. We continue to monitor our five-year drilling plan and will make further revisions as appropriate. Reducing the 2020 capital budget may impact production levels in 2021 and forward$1.5 billion. See Note 7—Long-Term Debt to the ~~extent fewer wells are brought online.~~

~~During the first quarter of 2020~~unaudited condensed consolidated financial statements and ~~the two preceding quarters, we recognized various impairment charges related to the decline in commodity prices~~“—Capital Resources and the value of our investment in Antero Midstream Corporation. At this time, we do not anticipate any further impairment charges in our equity method investment in Antero Midstream Corporation, as the value of our equity method investment has increased since the end of the first quarter of 2020. Additional impairment charges related to our assets may occur if we experience disruptions in production, additional or sustained declines in the forward commodity price strip from September 30, 2020, unresolved storage capacity restraints or other consequences caused by the COVID-19 pandemic.

~~In October 2020, the borrowing base supporting our~~Liquidity—Debt Agreements—Senior Secured Revolving Credit Facility was subject to its semi-annual redetermination and was re-affirmed our borrowing base at $2.85 billion. Lender commitments also remained unchanged at $2.64 billion, providing us with a consistent amount of available borrowings. Our next semi-annual borrowing base redetermination is in April 2021, which could impact our available borrowings and liquidity.Facility.”

In addition, our borrowing capacity is directly impacted by the amount of financial assurance we are required to provide in the form of letters of credit to third parties, primarily pipeline capacity providers. The amount of financial assurance we ~~must provide~~provided has not increased during the COVID-19 pandemic and, thus far, we have not experienced any losses due to counterparty risk. However, our ability to limit any additional financial assurance we are required to provide, as well as to protect ourselves from the counterparty risk of our financial hedges, may be limited in the future. Since the onset of the COVID-19 pandemic, we have timely serviced our debt and other obligations, and we have not ~~implemented or requested any concessions or~~ materially modified the terms of any agreements.

Financing and Asset Sales Program Highlights

Credit Facility

On October 26, 2021, we entered into an amended and restated senior secured revolving credit facility with a borrowing base of $3.5 billion and lender commitments of $1.5 billion. and matures on the earlier of (i) October 26, 2026 and (ii) the day that is 180 days prior to the earliest stated redemption date of any series of our senior notes. Lender commitments were reduced by $1.1 billion from the previous commitments of $2.64 billion to better align with our expected future liquidity needs. See Note 7—Long-Term Debt to the unaudited condensed consolidated financial statements and “—Capital Resources and Liquidity—Debt Agreements—Senior Secured Revolving Credit Facility” for more information.

Issuance of Senior Notes

On January 4, 2021, we issued $500 million of our 8.375% senior notes due July 15, 2026 (the “2026 Notes”) at par. On January 26, 2021, we issued $700 million of 7.625% senior notes due February 1, 2029 (the “2029 Notes”) at par. On June 1, 2021, we issued $600 million of 5.375% senior notes due March 1, 2030 (the “2030 Notes”). The ~~COVID-19 pandemic, commodity market volatility~~2026 Notes, 2029 Notes and ~~resulting financial market instability~~2030 Notes are ~~variables beyond~~unsecured and effectively subordinated to the Credit Facility to the extent of the value of the collateral securing the Credit Facility.

The 2026 Notes, 2029 Notes and ~~may adversely impact~~2030 Notes are guaranteed on a full and unconditional and joint and several senior unsecured basis by our ~~generation of funds from operating cash flows, distributions from unconsolidated affiliates, available borrowings under our~~existing subsidiaries that guarantee the Credit Facility and certain of our ~~ability~~future restricted subsidiaries. See Note 7—Long-Term Debt to ~~access~~ the ~~capital markets. We have announced $751 million in asset sales since December 2019, inclusive of up to $51 million of contingent consideration, with proceeds used~~unaudited condensed consolidated financial statements for absolute debt reduction. Any additional asset sales or excess cash flows is expected to be used for further debt reduction. Instability in the financial markets and uncertainty in the general business environment resulting from the COVID-19 pandemic may impact our ability to further execute our asset sale program on the terms and the timeframe previously anticipated.

~~Volumetric Production Payment Transaction~~

On August 10, 2020, we completed a volumetric production payment transaction and received net proceeds of approximately $215 million (the "VPP"). In connection with the VPP, we entered into a purchase and sale agreement, together with a conveyance agreement and production and marketing agreement, with J.P. Morgan Ventures Energy Corporation ("JPM-VEC") to convey, effective July 1, 2020, an overriding royalty interest in dry gas producing properties in West Virginia (the "VPP Properties") equal to 136,589,000 MMBtu over the expected seven-year term of the VPP.

~~We accounted for the VPP as a conveyance under Accounting Standard Codifications (“ASC”) Topic 932,~~ ~~Extractive Industries—Oil and Gas~~, and the net proceeds were recognized as deferred revenue as of September 30, 2020. Deferred revenue is recognized as volumes are delivered using the units-of-production method over the term of the VPP. Under the production and marketing agreement, we and our affiliates provide certain marketing services as JPM-VEC’s agent, and any income or expenses related to these services will be recorded as marketing revenue or marketing expenses (as the case may be).more information.

write off of a proportional amount of unamortized debt issuance costs will be included in our loss on early debt extinguishment during

the fourth quarter of 2021.

Convertible Notes Equitizations

On January 12, 2021, we completed a registered direct offering (the “January Share Offering”) of an aggregate of 31.4 million shares of our common stock at a price of $6.35 per share to certain holders of our 4.25% convertible senior notes due 2026 (the “2026 Convertible Notes”). We used the proceeds from the January Share Offering and approximately $63 million of borrowings under the Prior Credit Facility to repurchase from such holders $150 million aggregate principal amount of the 2026 Convertible Notes in privately negotiated transactions (the “January Convertible Note Repurchase,” and, collectively with the January Share Offering, the “January Equitization Transactions”).

On May 13, 2021, we completed a registered direct offering (the “May Share Offering”) of an aggregate of 11.6 million shares of our common stock at a price of $11.01 per share to certain holders of our 2026 Convertible Notes. We used the proceeds from the May Share Offering and approximately $26 million of borrowings under the Prior Credit Facility to repurchase from such holders $56 million aggregate principal amount of the 2026 Convertible Notes in privately negotiated transactions (the “May Convertible Note Repurchase,” and, collectively with the May Share Offering, the “May Equitization Transactions”). See Note 7—Long-Term Debt to the unaudited condensed consolidated financial statements for more information.

Drilling Partnership

On February 17, 2021, we announced the formation of a drilling partnership with QL Capital Partners (“QL”), an affiliate of Quantum Energy Partners, for our 2021 through 2024 drilling program. Under the terms of the arrangement, each year in which QL participates represents an annual tranche, and QL will be conveyed a working interest in any wells spud by us during such tranche year. For 2021, together with QL, we agreed to a capital budget for such annual tranche, and for each subsequent year through 2024, we will propose a capital budget and estimated internal rate of return (“IRR”) for all wells to be spud during such year and, subject to the mutual agreement of the parties that the estimated IRR for the year exceeds a specified return, QL will be obligated to participate in such tranche. We develop and manage the drilling program associated with each tranche, including the selection of wells. Additionally, for each annual tranche in which QL participates, together with QL, we will enter into an assignment, bill of sale and conveyance pursuant to which QL will be conveyed a proportionate working interest percentage in each well spud in that year, which conveyance will not be subject to any reversion.

Under the terms of the arrangement, QL will fund 20% of development capital for wells spud in 2021 and is expected to fund between 15% and 20% of development capital for wells spud from 2022 through 2024, which funding amounts represent QL’s proportionate working interest in such wells. Additionally, we may receive a carry in the form of a one-time payment from QL for each annual tranche if the IRR for such tranche exceeds certain specified returns, which will be determined no earlier than December 31 following the end of each tranche year. Capital costs in excess of, and cost savings below, a specified percentage of budgeted amounts for each annual tranche will be for our account. Subject to the preceding sentence, for any wells included in a tranche, QL is obligated and responsible for its working interest share of costs and liabilities, and is entitled to its working interest share of revenues, associated with such wells for the life of such ~~derivative instruments.~~wells. If we present a capital budget for an annual tranche with an estimated IRR equal to or exceeding a specified return that QL in good faith believes is less than such specified return and QL elects not to participate, we will not be obligated to offer QL the opportunity to participate in subsequent annual tranches.

Overriding Royalty Interest Additional Contributions

On June 15, 2020, we announced the consummation of a transaction with an affiliate of Sixth Street Partners, LLC (“Sixth Street”) relating to certain overriding royalty interests across our existing asset base (the “ORRIs”). In connection with the transaction, we contributed the ORRIs to a newly formed subsidiary, Martica Holdings LLC (“Martica”)~~, and Sixth Street at~~. At the initial closing, Sixth Street contributed $300 million in cash (subject to customary adjustments) and agreed to contribute up to an additional $102 million in cash if certain production ~~targets~~thresholds attributable to the ORRIs ~~are~~were achieved in the third quarter of 2020 and first quarter of 2021.

Prior to Sixth Street achieving an internal rate of return of 13% and 1.5x cash-on-cash return (the “Hurdle”), Sixth Street will receive all distributions in respect of the Initial PDP Override and the Development Override, and we will receive all distributions in respect of the Incremental Override, unless certain production targets are not achieved, in which case Sixth Street will receive some or all of the distributions in respect of the Incremental Override. Following Sixth Street achieving the Hurdle, we will receive 85% of the distributions in respect of the ORRIs to which Sixth Street was entitled immediately prior to the Hurdle being achieved.

~~Production and Financial Results~~

~~Three months ended~~ September 30, ~~2020~~~~. For the three months ended September 30, 2020~~2021, our ~~net production totaled 347 Bcfe, or 3,772 MMcfe per day, a 12% increase in daily~~fixed price natural gas, equivalent production compared to 310 Bcfe, or 3,367 MMcfe per day, for the three months ended September 30, 2019. Production increases resulted from an increase in the number of producing wells as a result of our drilling and completion activity. Our average price received for production for the three months ended September 30, 2020 was $2.30 per Mcfe compared to $2.74 per Mcfe for the three months ended September 30, 2019. These prices are before the effects of gains on settled commodity derivatives in both periods and included the proceeds related to a certain lawsuit in the three months ended September 30, 2019. Our average realized price after the effects of gains on settled commodity derivatives was $2.92 per Mcfe for the three months ended September 30, 2020 compared to $3.13 per Mcfe for the three months ended September 30, 2019, a decrease of 7%.

We generated consolidated cash flows from operations of $176 million, net loss attributable to Antero Resources of $536 million, and Adjusted EBITDAX of $272 million for the three months ended September 30, 2020. This compares to consolidated cash flows from operations of $198 million, consolidated net loss attributable to Antero Resources of $879 million, and Adjusted EBITDAX of $258 million for the three months ended September 30, 2019. See “—Non-GAAP Financial Measures” for a definition of Adjusted EBITDAX and a reconciliation of Adjusted EBITDAX to net cash provided by operating activities and net income (loss).

Cash flows from operations decreased by $22 million for the three months ended September 30, 2020 compared to the prior year period primarily due to decreases in commodity prices both before and after the effects of settled commodity derivatives, increases in processing and transportation costs, and changes in current assets and liabilities. Consolidated net loss attributable to

Antero Resources of $536 million for the three months ended September 30, 2020 decreased from consolidated net loss attributable to Antero Resources of $879 million for the three months ended September 30, 2019 primarily due to impairments of oil and ~~gas properties in 2019, partially offset by decreases in commodity derivative fair value gains (losses) and commodity prices and expense increases in processing and transportation costs.~~NGL swap positions excluding Martica, our consolidated VIE, were as follows:

Adjusted EBITDAX increased from $258 million for the three months ended September 30, 2019 to $272 million for the three months ended September 30, 2020, an increase of 6%, primarily due to higher commodity derivative settlement gains and decreased operating expenses per Mcfe, partially offset by lower commodity prices between periods.

~~Nine months ended September 30, 2020.~~ For the nine months ended September 30, 2020 our net production totaled 974 Bcfe, or 3,554 MMcfe per day, a 10% increase in daily combined production compared to 882 Bcfe, or 3,232 MMcfe per day, for the nine months ended September 30, 2019. Production increases resulted from an increase in the number of producing wells as a result of our drilling and completion activity. Our average price received for production, before the effects of gains on settled commodity derivatives for the nine months ended September 30, 2020 was $2.15 per Mcfe compared to $3.15 per Mcfe for the nine months ended September 30, 2019. Our average realized price, after the effects of gains on settled commodity derivatives in both periods and including the proceeds related to a certain lawsuit in the three months ended September 30, 2019, was $2.91 per Mcfe for the nine months ended September 30, 2020 compared to $3.44 per Mcfe for the nine months ended September 30, 2019, a decrease of 15%.

We generated consolidated cash flows from operations of $493 million, net loss attributable to Antero of $1.3 billion, and Adjusted EBITDAX of $703 million for the nine months ended September 30, 2020. This compares to consolidated cash flows from operations of $956 million, consolidated net income attributable to Antero Resources of $142 million, and Adjusted EBITDAX of $952 million for the nine months ended September 30, 2019.

Cash flows from operations decreased by $463 million for the nine months ended September 30, 2020 compared to the prior year period primarily due to decreases in commodity prices both before and after the effects of settled commodity derivatives, increases in processing and transportation costs and changes in current assets and liabilities. Consolidated net loss attributable to Antero Resources of $1.3 billion for the nine months ended September 30, 2020 decreased from consolidated net income attributable to Antero Resources of $142 million for the nine months ended September 30, 2019 primarily due to lower commodity prices between periods as well as the gain on deconsolidation of Antero Midstream Partners in 2019 partially offset by impairment of oil and gas properties in 2019. The nine months ended September 30, 2020 was also impacted by an impairment of equity investment due to the decline in Antero Midstream Corporation’s fair value, Antero Midstream Corporation’s reporting a loss for such period, and the decreases in commodity prices both before and after the effects of settled commodity derivatives and increases in gathering, compression, processing and transportation costs.

Adjusted EBITDAX decreased from $982 million for the nine months ended September 30, 2019 to $703 million for the nine months ended September 30, 2020, a decrease of 26%, primarily due to the decrease in commodity prices of 32% per Mcfe before and 15% per Mcfe after the effects of settled commodity derivatives, and increased processing and transportation costs per Mcfe. A portion of the cost increases are the result of the deconsolidation of Antero Midstream Partners as costs that were previously eliminated in consolidation are now expensed.

~~2020 Capital Budget and Capital Spending~~

On April 20, 2020, we announced our revised 2020 drilling and completion capital budget of $750 million. We do not include acquisitions in our capital budget. We periodically review our capital expenditures and adjust our budget and its allocation based on commodity prices, takeaway constraints, operating cash flow and liquidity.

~~Three months ended September 30, 2020.~~ ~~For the three months ended September 30, 2020,~~ our capital expenditures were approximately $151 million, including drilling and completion costs of $141 million, leasehold acquisitions of $9 million, and other capital expenditures of $1 million. Our capital expenditures for the three months ended September 30, 2019 of approximately $292 million included drilling and completion costs of $278 million, leasehold acquisitions of $13 million, and other capital expenditures of $1 million. This 48% reduction in capital costs was a result of our decreased activity levels during the third quarter of 2020 as well as well cost savings initiatives, which include savings resulting from service cost deflation, sand and water logistics optimization, and operational efficiency gains.

~~Nine months ended September 30, 2020.~~ ~~For the nine months ended September 30, 2020,~~ our capital expenditures were approximately $726 million, including drilling and completion costs of $694 million, leasehold acquisitions of $31 million, and other capital expenditures of $1 million. Our exploration and production capital expenditures for the nine months ended September 30, 2019 of approximately $1.1 billion included drilling and completion costs of $958 million, leasehold acquisitions of $70 million, and

~~Table of Contents~~

other capital expenditures of $6 million. This 30% reduction in capital costs was a result of our decreased activity levels during 2020 as well as our well cost savings initiatives, which include savings resulting from service cost deflation, sand and water logistics optimization, and operational efficiency gains.

In addition, consolidated capital expenditures for the nine months ended September 30, 2019 included gathering and compression expenditures of $48 million and water handling and treatment expenditures of $24 million. Antero Midstream Partners also invested $25 million in a joint venture. These expenditures relate to the period prior to deconsolidation of Antero Midstream Partners on March 12, 2019.

~~Hedge Position (Excluding Martica)~~

As of September 30, 2020, we had fixed price natural gas swap contracts on NYMEX Henry Hub for the period from October 2020 through December 2023 covering 1.3 Tcf of our projected natural gas production at a weighted average index price of $2.69 per MMBtu, including contracts for the remainder of 2020 of approximately 190 Bcf of natural gas at a weighted average index price of $2.84 per MMBtu. As of September 30, 2020, we also had basis swaps for the period from October 2020 through December 2024 for approximately 78.6 Bcf of our projected natural gas production with pricing differentials ranging from $0.35 to $0.53 per MMBtu that hedge the difference between TCO and the NYMEX Henry Hub. In addition, we have a call option agreement, which entitles the holder, if exercised, to enter into a fixed price swap agreement for approximately ~~428 MMBtu per day~~156 Bcf at a price of $2.77 per MMBtu in 2024.

As of September 30, 2020, we had fixed price oil swap contracts on NYMEX-WTI for the period from October 2020 through December 2021 covering approximately 3.5 million barrels of our projected oil production at a weighted average index price of $55.48 per barrel. Additionally, we had fixed price propane swap contracts on ARA Propane for the period from October 2020 through December 2020 covering approximately 0.9 million barrels of our projected propane production at a weighted average index price of $0.65 per gallon. We also had fixed price ethane swap contracts on OPIS Ethane Mt Belv for the period from October 2020 through March 2021 covering approximately 4.0 million barrels of our projected ethane production at a weighted average index price of $0.20 per gallon.

As of September 30, ~~2020,~~2021, our natural gas basis swap positions, which settle on the pricing index to basis differential of the Columbia Gas Transmission pipeline (“TCO”) to the NYMEX Henry Hub natural gas price were as follows:

As of September 30, 2021, we had natural gas and NGL contracts that fix the Mont Belvieu index price for natural gasoline to percentages of WTI as follows:


				Weighted Average
Commodity / Settlement Period	Index to Basis Differential	Contracted Volume		Payout Ratio
Gas Liquids
October-December 2021	Mont Belvieu Natural Gasoline to WTI	858	MBbl	77	%

As of September 30, 2021, we also had an embedded put option tied to NYMEX pricing for the production volumes associated with our retained interest in the VPP (as defined below) properties of ~~120,667,000 MMBtu~~95 Bcf remaining through December 31, 2026 at a weighted average strike price of ~~$2.60~~$2.57 per MMBtu.

We believe our hedge position provides some certainty to cash flows supporting our future operations and capital spending plans. As of September 30, ~~2020,~~2021, the estimated fair value of our commodity derivative contracts was a net liability of approximately ~~$130 million.~~$1.7 billion. See Note 11—Derivative Instruments to the unaudited condensed consolidated financial statements for more information.

Results of Operations

We have three operating segments: ~~(1)~~(i) the exploration, development and production of natural gas, NGLs, and oil; ~~(2)~~(ii) marketing and utilization of excess firm transportation ~~capacity gathering~~capacity; and ~~processing; and (3)~~(iii) midstream services through our equity method investment in Antero Midstream Corporation. Revenues from Antero Midstream Corporation’s operations were primarily derived from intersegment transactions for services provided to our exploration and production operations by Antero Midstream Partners. All intersegment transactions were eliminated upon consolidation, including revenues from water handling and treatment services provided by Antero Midstream Partners LP (“Antero Midstream Partners”), which we capitalized as proved property development costs. ~~Through March 12, 2019, the results of Antero~~ ~~Midstream~~ ~~Partners were included in our consolidated financial statements. Effective March 13, 2019, the results of Antero~~ ~~Midstream~~ Partners are no longer included in our results; however, our disclosures include the segments of our unconsolidated affiliates due to their significance to our operations. See Note 3—Deconsolidation of Antero Midstream Partners LP and Note 18—Segment Information to the unaudited condensed consolidated financial statements. Marketing revenues are primarily derived from activities to purchase and sell third-party natural gas and NGLs and to market and utilize excess firm transportation capacity. See Note 16—Reportable Segments to the unaudited condensed consolidated financial statements.

Average sales prices shown in the table reflect both the before and after effects of our settled commodity derivatives. Our calculation of such after effects includes gains on settlements of commodity derivatives, which do not qualify for hedge accounting because we do not designate or document them as hedges for accounting purposes. Oil and NGLs production was converted at 6 Mcf per Bbl to calculate total Bcfe production and per Mcfe amounts. This ratio is an estimate of the equivalent energy content of the products and does not necessarily reflect their relative economic value.

Natural gas sales. Revenues from ~~production~~sales of natural gas ~~decreased~~increased from ~~$524 million for the three months ended September 30, 2019 to~~ $436 million for the three months ended September 30, 2020 ~~a decrease~~to $885 million for the three months ended September 30, 2021, an increase of ~~$88~~$449 million, or ~~17%~~103%. Lower natural gas production volumes during the three months ended September 30, 2021 accounted for an approximate $39 million decrease in year-over-year natural gas sales revenue (calculated as the change in year-to-year volumes times the prior year average price), and increases in commodity prices (excluding the effects of derivative settlements) accounted for an approximate $488 million increase in year-over-year gas sales revenue (calculated as the change in the year-to-year average price excluding the net proceeds from the litigation times current year production volumes).

NGLs sales. Revenues from sales of NGLs increased from $327 million for the three months ended September 30, 2020 to $598 million for the three months ended September 30, 2021, an increase of $271 million, or 83% (calculated as the change in year-over-year volumes times the change in year-to-year average price). Higher natural gas production volumes during the three months ended September 30, 2020 accounted for an approximate $40 million increase in year-over-year natural gas revenues (calculated as the change in year-to-year volumes times the prior year average price), and changes in our prices, excluding the effects of derivative settlements, accounted for an approximate $128 million decrease in year-over-year revenues (calculated as the change in the year-to-year average price times current year production volumes).

~~NGLs sales~~. Revenues from production of NGLs increased from $285 million for the three months ended September 30, 2019 to $327 million for the three months ended September 30, 2020, an increase of $42 million, or 15% (calculated as the change in year-over-year volumes times the change in year-to-year average price). IncreasedLower NGLs production volumes accounted for an approximate ~~$50~~$76 million ~~increase~~decrease in year-over-year NGL revenues (calculated as the change in year-to-year volumes times the prior year average price), and ~~changes~~increases in ~~our~~commodity prices, excluding the effects of derivative settlements, accounted for an approximate $8$347 million

~~million decrease in year-over-year revenues (calculated as the change in the year-to-year average price times current year production volumes).~~

~~Oil sales~~. Revenues from production of oil decreased from $41 million for the three months ended September 30, 2019 to $34 million for the three months ended September 30, 2020, a decrease of $7 million, or 16% (calculated as the change in year-over-year volumes times the change in year-to-year average price). Increased oil production volumes accounted for an approximate $23 million increase in year-over-year oil revenues (calculated as the change in year-to-year volumes times the prior year average price), and changes in our prices, excluding the effects of derivative settlements, accounted for an approximate $30 million decrease in year-over-year revenues (calculated as the change in the year-to-year average price times current year production volumes).

~~Commodity derivative fair value gains (losses).~~ To achieve more predictable cash flows, and to reduce our exposure to price fluctuations, we enter into fixed for variable price swap contracts, basis swap contracts and collar contracts when management believes that favorable future sales prices for our production can be secured. Because we do not designate these derivatives as accounting hedges, they do not receive hedge accounting treatment. Consequently, all mark-to-market gains or losses, as well as cash receipts or payments on settled derivative instruments, are recognized in our statements of operations. The commodity derivative fair value gains (losses) included $120 million and $234 million gains on cash settled derivatives for the three months ended September 30, 2019 and 2020, respectively. For the three months ended September 30, 2019 and 2020, our commodity hedges resulted in derivative fair value gains of $221 million and losses of $515 million, respectively.

Commodity derivative fair value gains or losses vary based on future commodity prices and have no cash flow impact until the derivative contracts are settled or monetized prior to settlement. Derivative asset or liability positions at the end of any accounting period may reverse to the extent future commodity prices increase or decrease from their levels at the end of the accounting period, or as gains or losses are realized through settlement. We expect continued volatility in commodity prices and the related fair value of our derivative instruments in the future.

~~Amortization of deferred revenue, VPP.~~ The three months ended September 30, 2020 include amortization of $5 million of deferred revenues associated with the VPP, which relate to the production volumes delivered under the terms of the agreement during such period at approximately $1.61 per MMBtu. See Note 4—Transactions to the unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for more information on this transaction.

~~Other income~~~~. Other income remained relatively consistent at $1 million for the three months ended September 30, 2019 and 2020.~~

~~Lease operating expense~~. Lease operating expense decreased from $36 million for the three months ended September 30, 2019 to $21 million for the three months ended September 30, 2020, a decrease of $15 million, or 40%. On a per unit basis, lease operating expenses decreased from $0.12 for the three months ended September 30, 2019 to $0.06 for the three months ended September 30, 2020, primarily due to lower water handling costs resulting from improved operating efficiencies including the reuse of produced and flowback water in completion operations.

~~Gathering, compression, processing, and transportation expense.~~ Gathering, compression, processing, and transportation expense increased by $53 million, or 9%, from $604 million for the three months ended September 30, 2019 to $657 million for the three months ended September 30, 2020 primarily due to a 12% increase in production, partially offset by lower costs between periods. Gathering and compression costs decreased from $0.68 per Mcfe to $0.64 per Mcfe primarily as a result of lower fuel costs as a result of decreased natural gas prices and a $12 million incentive fee rebate from Antero Midstream Corporation. Processing costs primarily decreased from $0.74 to $0.71 per Mcfe as a result of decreased terminal fees at Mariner East 2. Our transportation costs increased from $0.53 per Mcfe to $0.55 per Mcfe due to increased rates on the Rockies Express pipeline.

~~Production and ad valorem tax expense.~~Production and ad valorem taxes decreased from $29 million for the three months ended September 30, 2019 to $26 million for the three months ended September 30, 2020, a decrease of $3 million, or 11%. This decrease is primarily as a result of decreases in commodity prices. Production and ad valorem taxes as a percentage of natural gas revenues was relatively consistent at 6% in the three months ended September 30, 2019 and 2020.

~~Impairment of oil and gas properties~~. During the three months ended September 30, 2019, we recognized an $881 million impairment to write-down our Utica Shale proved properties to fair value because the carrying value of such properties exceeded the estimated undiscounted cash flows based on future strip commodity prices as of September 30, 2019. We also recorded $160 million of impairments for the three months ended September 30, 2019 related to expiring leases and the design and initial costs related to pads we no longer plan to place into service. During the three months ended September 30, 2020, we recognized impairment of $29 million primarily related to expiring leases and the design and initial costs related to pads we no longer plan to place into service.

~~Table of Contents~~

~~Depletion, depreciation, and amortization expense (“DD&A”)~~. DD&A expense decreased from $242 million for the three months ended September 30, 2019 to $238 million for the three months ended September 30, 2020, a decrease of $4 million, or 1%. DD&A per Mcfe decreased from $0.78 per Mcfe during the three months ended September 30, 2019 to $0.69 per Mcfe during the three months ended September 30, 2020, primarily due to a lower depletable cost basis as a result of the Utica proved property impairment of $881 million in 2019, which was partially offset by downward reserve revisions that resulted from lower SEC prices between periods.

~~General and administrative expense~~. General and administrative expense (excluding equity-based compensation expense) was $32 million for the three months ended September 30, 2019 and $26 million for the three months ended September 30, 2020, a decrease of $6 million, or 19%. This decrease was primarily due to decreases in employee related expenses in the three months ended September 30, 2020 as a result of ongoing cost savings initiatives related to lower headcount in 2020. We had 569 employees as of September 30, 2019 and 520 employees as of September 30, 2020. On a per-unit basis, general and administrative expense excluding equity-based compensation decreased by 30%, from $0.10 per Mcfe during the three months ended September 30, 2019 to $0.07 per Mcfe during the three months ended September 30, 2020 as a result of higher production volumes and lower overall costs between periods.

~~Equity-based compensation expense~~. Noncash equity-based compensation expense was $4 million for the three months ended September 30, 2019 and $6 million for the three months ended September 30, 2020, an increase of $2 million, or 47%. This increases was primarily due to new equity-based compensation awards granted in the three months ended September 30, 2020. See Note 10—Equity Based Compensation to the unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for more information on equity-based compensation awards.

~~Contract termination and rig stacking.~~ We incurred contract termination and rig stacking costs of less than $1 million during the three months ended September 30, 2019 compared to $1 million for the three months ended September 30, 2020. Contract termination and rig stacking costs represent fees incurred upon the delay or cancellation of drilling and completion contracts with third-party contractors in order to align our drilling and completion activity level with our capital budget.

~~Discussion of the Marketing Segment for the Three Months Ended September 30, 2019 Compared to the Three Months Ended September 30, 2020~~

~~Marketing.~~ We have entered into long-term firm transportation agreements for our current and expected future production to secure guaranteed capacity to favorable markets. Where feasible, we purchase and sell third-party natural gas and NGLs to utilize our excess firm transportation capacity, or release capacity to third parties to conduct these activities on our behalf, to reduce our net costs related to the unused capacity under these transportation agreements.

Operating losses on our marketing activities, or our net marketing expense, decreased from $62 million, or $0.20 per Mcfe, for the three months ended September 30, 2019 to $37 million, or $0.11 per Mcfe, for the three months ended September 30, 2020. The decrease was driven by higher volumes and the mitigation of some of our excess firm transportation expense.

Marketing revenues increased from $47 million for the three months ended September 30, 2019 to $92 million for the three months ended September 30, 2020, an increase of $45 million, or 96%. Marketing expenses increased from $108 million for the three months ended September 30, 2019 to $129 million for the three months ended September 30, 2020, an increase of $21 million, or 19%. Marketing expenses include firm transportation costs related to current excess firm capacity as well as the cost of third-party purchased gas and NGLs. Firm transportation costs included in the expenses above were $62 million and $32 million for the three months ended September 30, 2019 and 2020, respectively.

~~Discussion of Antero Midstream Corporation Segment for the Three Months Ended September 30, 2019 Compared to the Three Months Ended September 30, 2020~~

~~Antero Midstream Corporation.~~ Revenue from the Antero Midstream Corporation segment decreased from $244 million for the three months ended September 30, 2019 to $235 million for the three months ended September 30, 2020, a decrease of $9 million, or 4%, primarily due to a reduction in water handling revenues. Total operating expenses related to the segment decreased from $586 million for the three months ended September 30, 2019 to $82 million for the three months ended September 30, 2020. The decrease was primarily due to impairment expense of $457 million on Antero Midstream Corporation’s wastewater treatment facility and related goodwill and customer relationships in the three months ended September 30, 2019.

~~Table of Contents~~

~~Discussion of Items Not Allocated to Segments for the Three Months Ended September 30, 2019 Compared to the Three Months Ended September 30, 2020~~

~~Interest expense.~~ Our interest expense was relatively flat at $48 million for each of the three months ended September 30, 2019 and 2020 due to lower total indebtedness resulting from repurchases of our unsecured senior notes at prices below their stated value, partially offset by the interest that accrued on the newly issued 2026 Convertible Notes (as defined below). Interest expense included approximately $2.6 million and $3.1 million of non-cash amortization of deferred financing costs for the three months ended September 30, 2019 and 2020, respectively.

~~Transaction expense.~~ We incurred transaction expense of less than $1 million in the three months ended September 30, 2020 and did not incur comparable costs in the three months ended September 30, 2019. These expenses included legal and transaction fees associated with the ORRI transaction. See Note 4—Transactions to the unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for more information on this transaction.

~~Income tax benefit~~. Income tax benefit decreased from a deferred tax benefit of $273 million, with an effective tax rate of 24%, for the three months ended September 30, 2019 to a deferred tax benefit of $169 million, with an effective tax rate of 23%, for the three months ended September 30, 2020. The change was primarily a result of an increase in book income due to the impairment of proved properties in the Utica Shale in the prior period.

~~Natural gas sales~~. Revenues from production of natural gas decreased from $1.7 billion for the nine months ended September 30, 2019 to $1.2 billion for the nine months ended September 30, 2020, a decrease of $520 million, or 30% (calculated as the change in year-over-year volumes times the change in year-to-year average price). Higher natural gas production volumes during the nine months ended September 30, 2020 accounted for an approximate $90 million increase in year-over-year natural gas revenues (calculated as the change in year-to-year volumes times the prior year average price), and changes in our prices, excluding the effects of derivative settlements, accounted for an approximate $610 million decrease in year-over-year revenues (calculated as the change in the year-to-year average price times current year production volumes).

~~NGLs sales~~. Revenues from production of NGLs decreased from $903 million for the nine months ended September 30, 2019 to $797 million for the nine months ended September 30, 2020, a decrease of $106 million, or 12% (calculated as the change in year-over-year volumes times the change in year-to-year average price). Increased NGLs production volumes accounted for an approximate $196 million increase in year-over-year NGL revenues (calculated as the change in year-to-year volumes times the prior year average price), and changes in our prices, excluding the effects of derivative settlements, accounted for an approximate $302

Commodity derivative fair value gains (losses). To achieve more predictable cash flows, and to reduce our exposure to price fluctuations, we enter into fixed for variable price swap contracts, basis swap contracts and collar contracts when management believes that favorable future sales prices for our production can be secured. Because we do not designate these derivatives as accounting hedges, they do not receive hedge accounting treatment. Consequently, all mark-to-market gains or losses, as well as cash receipts or payments on settled derivative instruments, are recognized in our statements of operations. ~~The commodity derivative fair value gains (losses) included $262 million and $759 million of gains on cash settled derivatives for~~For the ~~nine~~three months ended September 30, ~~2019~~2020 and ~~2020, respectively. For the nine months ended September 30, 2019 and 2020,~~2021, our commodity hedges resulted in derivative fair value ~~gains~~losses of ~~$472~~$515 million and $1.3 billion, respectively. For the three months ended September 30, 2020, commodity derivative fair value losses included $234 million of ~~$117~~cash proceeds for gains on settled derivatives. For the three months ended September 30, 2021, commodity derivative fair value losses included $416 million ~~respectively.~~of cash payments on commodity settled derivatives losses.

Amortization of deferred revenue, VPP. ~~The nine months ended September 30, 2020 include amortization of $5 million~~Amortization of deferred revenues associated with the VPP ~~which relate~~increased from $5 million for the three months ended September 30, 2020 to $11 million for the ~~production volumes delivered under~~three months ended September 30, 2021 as a result of the VPP closing in August 2020. Under the terms of the agreement, ~~during such period~~the production volumes are delivered at approximately $1.61 per ~~MMBtu.~~MMBtu over the contractual term. See Note 4—3—Transactions to the unaudited condensed consolidated financial statements ~~included elsewhere in this Quarterly Report on Form 10-Q~~ for more information on this transaction.

~~Other income~~~~. Other income remained relatively consistent at $3 million and $2 million for the nine months ended September 30, 2019 and 2020, respectively.~~

Lease operating expense. Lease operating expense ~~decreased~~increased from ~~$119~~$21 million for the ~~nine months ended September 30, 2019 to $72 million for the nine~~three months ended September 30, 2020 ~~a decrease~~to $25 million for the three months ended September 30, 2021, an increase of ~~$47~~$4 million or ~~39%~~18%.

~~Contract termination and rig stacking.~~ We incurred contract termination and rig stacking costs of $14 million during the nine months ended September 30, 2019 compared to $12 million for the nine months ended September 30, 2020. Contract termination and rig stacking costs represent fees incurred upon the delay or cancellation of drilling and completion contracts with third-party contractors in order to align our drilling and completion activity level with our capital budget.

~~Discussion of the~~ Marketing Segment ~~for the~~ ~~Nine months ended September 30, 2019~~ ~~Compared to the~~ ~~Nine months ended September 30, 2020~~

Marketing. Where feasible, we purchase and sell third-party natural gas and NGLs and market our excess firm transportation capacity, or engage third parties to conduct these activities on our behalf, to optimize the revenues and mitigate costs from these transportation agreements. We have entered into long-term firm transportation agreements for a significant portion of our current and expected future production to secure guaranteed capacity to favorable markets. Where feasible, we purchase and sell third-party natural gas and NGLs to utilize our excess firm transportation capacity, or release capacity to third parties to conduct these activities on our behalf, in order to reduce our net costs related to the unused capacity under these transportation agreements.

~~Our net~~Net marketing ~~expense~~expenses decreased from ~~$208~~$37 million, or ~~$0.24~~$0.11 per Mcfe, for the ~~nine~~three months ended September 30, ~~2019~~2020 to ~~$133~~$34 million, or ~~$0.14~~$0.11 per Mcfe, for the ~~nine~~three months ended September 30, ~~2020.~~2021. The decrease in net marketing expense was driven by higher marketing volumes and ~~the mitigation of~~margins that mitigated some of our excess firm transportation expense.

Marketing revenues ~~remained relatively flat at $201 million and $202~~increased from $91 million for the ~~nine~~three months ended September 30, ~~2019 and~~ 2020 ~~respectively.~~to $233 million for the three months ended September 30, 2021, an increase of $142 million due to increased marketing volumes.

Marketing expenses ~~decreased~~increased from ~~$409~~$129 million for the ~~nine months ended September 30, 2019 to $335 million for the nine~~three months ended September 30, 2020 ~~a decrease~~to $267 million for the three months ended September 30, 2021, an increase of ~~$74~~$138 million, or ~~18%~~107%. Marketing expenses include firm transportation costs related to current excess firm capacity as well as the cost of third-party purchased gas and NGLs. Firm transportation costs included in the expenses above were ~~$127~~$32 million and ~~$122~~$28 million for the ~~nine~~three months ended September 30, ~~2019~~2020 and ~~2020,~~2021, respectively.

Equity Method Investment in Antero Midstream Corporation

~~Discussion of~~Antero Midstream Corporation. Revenue from the Antero Midstream Corporation ~~Segment~~segment decreased from $233 million for the ~~Nine~~three months ended September 30, ~~2019~~ ~~Compared~~2020 to $225 million for the three months ended September 30, 2021, a decrease of $8 million, or 4%, primarily due to lower water handling revenue due to decreased well completions period-over-period and lower gathering and compression revenues as a result of reduced throughput between periods. Total operating expenses related to the ~~Nine~~segment remained relatively consistent between periods at $82 million and $83 million for the three months ended September 30, 2020

Through March 12, 2019, the results of Antero Midstream Partners are included in our consolidated financial statements. Effective March 13, 2019, we no longer consolidate the results of Antero Midstream Partners in our results. As such, the nine months and 2021, respectively.

Interest expense. Our interest expense decreased from $48 million for the three months ended September 30, ~~2019 include~~2020 to $45 million for the ~~results~~three months ended September 30, 2021, a decrease of ~~Antero Midstream Partners through March 12, 2019.~~$3 million or 5%, primarily due to the reduction in debt as a result of the repurchase of certain our unsecured senior notes, paydown of our Prior Credit Facility and increased interest income between periods, partially offset by interest that accrued on the 2026 Notes, 2029 Notes and 2030 Notes, each of which was issued after September 30, 2020.

Gain (loss) on early extinguishment of debt. During the three months ended September 30, 2020, we recognized a gain on early extinguishment of debt of $56 million related to $1.1 billion principal amount of debt that we repurchased at a weighted average discount of 13%. During the three months ended September 30, 2021, we redeemed $175 million of our 2026 Notes at a redemption price of 108.375% of par, plus accrued and unpaid interest, which resulted in a loss on early debt extinguishment of $17 million. See Note ~~3—Deconsolidation of Antero Midstream Partners LP~~7—Long-Term Debt to the unaudited condensed consolidated financial ~~statements.~~statements for more information.

Transaction expense. Transaction expense remained consistent between periods at less than $1 million for both the three months ended September 31, 2020 and 2021.

Income tax benefit. Income tax benefit decreased from $169 million, with an effective tax rate of 23%, for the three months ended September 30, 2020 to $159 million, with an effective tax rate of 22%, for the three months ended September 30, 2021, a decrease of $10 million. The decrease was primarily due to unfavorable adjustments related to the West Virginia law change effecting apportionment and sourcing methodologies resulting in lower income tax benefit for the period ending September 30, 2021.

The average realized price for the nine months ended September 30, 2021 includes $85 million of net litigation proceeds related to a favorable litigation judgment. See Note 14—Contingencies to the unaudited condensed consolidated financial statements for further discussion on the litigation proceeds. Excluding the effect of the litigation proceeds received, the average realized price would have been $3.46 per Mcf.

Natural gas sales. Revenues from sales of natural gas increased from $1.2 billion for the nine months ended September 30, 2020 to $2.2 billion, which included litigation proceeds of $85 million, for the nine months ended September 30, 2021, an increase of $1.0 billion, or 84%. See Note 14— Contingencies to the unaudited condensed consolidated financial statements for more information on the litigation proceeds.

Excluding net litigation proceeds, lower natural gas production volumes during the nine months ended September 30, 2021 accounted for an approximate $53 million decrease in year-over-year natural gas sales revenue (calculated as the change in year-to-year volumes times the prior year average price excluding the net proceeds from the litigation), and increases in commodity prices (excluding the effects of derivative settlements) accounted for an approximate $984 million increase in year-over-year gas sales revenue (calculated as the change in the year-to-year average price excluding the net proceeds from the litigation times current year production volumes).

NGLs sales. Revenues from sales of NGLs increased from $797 million for the nine months ended September 30, 2020 to $1.5 billion for the nine months ended September 30, 2021, an increase of $706 million, or 89% (calculated as the change in year-over-year volumes times the change in year-to-year average price). Lower NGLs production volumes accounted for an approximate $118 million decrease in year-over-year NGL revenues (calculated as the change in year-to-year volumes times the prior year average price), and increases in commodity prices, excluding the effects of derivative settlements, accounted for an approximate $824 million increase in year-over-year revenues (calculated as the change in the year-to-year average price times current year production volumes).

Oil sales. Revenues from sales of oil increased from $78 million for the nine months ended September 30, 2020 to $153 million for the nine months ended September 30, 2021, an increase of $75 million, or 96% (calculated as the change in year-over-year volumes times the change in year-to-year average price). Lower oil production volumes accounted for a $11 million decrease in year-over-year oil revenues (calculated as the change in year-to-year volumes times the prior year average price), and increases in commodity prices, excluding the effects of derivative settlements, accounted for an approximate $86 million increase in year-over-year revenues (calculated as the change in the year-to-year average price times current year production volumes).

Commodity derivative fair value gains (losses). To achieve more predictable cash flows, and to reduce our exposure to price fluctuations, we enter into fixed for variable price swap contracts, basis swap contracts and collar contracts when management believes that favorable future sales prices for our production can be secured. Because we do not designate these derivatives as accounting hedges, they do not receive hedge accounting treatment. Consequently, all mark-to-market gains or losses, as well as cash receipts or payments on settled derivative instruments, are recognized in our statements of operations. For the nine months ended September 30, 2020, our commodity hedges resulted in derivative fair value losses of $117 million. For the nine months ended September 30, 2021, our commodity hedges resulted in derivative fair value loss of $2.3 billion. Commodity derivative fair value losses included $759 million of cash proceeds for gains on settled derivatives for the nine months ended September 30, 2020. For the nine months ended September 30, 2021, commodity derivative fair value losses included $481 million of cash payments on commodity derivative losses as well as $5 million for payments on derivative monetizations.

Amortization of deferred revenue, VPP. Amortization of deferred revenues associated with the VPP increased from $5 million for the nine months ended September 30, 2020 to $34 million for the nine months ended September 30, 2021 as a result of the VPP closing in August 2020. Under the terms of the agreement, the production volumes are delivered at approximately $1.61 per MMBtu over the contractual term. See Note 3—Transactions to the unaudited condensed consolidated financial statements for more information on this transaction.

Lease operating expense. Lease operating expense was $72 million for each of the nine months ended September 30, 2020 and 2021. On a per unit basis, lease operating expenses increased from $0.07 per Mcfe for the nine months ended September 30, 2020 to $0.08 per Mcfe for the three months ended September 30, 2021 primarily due to lower production volumes.

Gathering, compression, processing, and transportation expense. Gathering, compression, processing, and transportation expense remained relatively flat at $1.9 billion for both the nine months ended September 30, 2020 and 2021. Gathering and compression costs increased from $0.63 per Mcfe for the nine months ended September 30, 2020 to $0.74 per Mcfe for the nine months ended September 30, 2021, primarily due to higher fuel costs as a result of increased natural gas prices and $36 million in incentive fee rebates from Antero Midstream Corporation received during the nine months ended September 30, 2020 that were not received during the nine months ended September 30, 2021. Processing costs decreased from $0.72 per Mcfe for the nine months ended September 30, 2020 to $0.67 per Mcfe for the nine months ended September 30, 2021, due to a decrease in C3+ NGL volumes as compared to total production volumes between periods, partially offset by increased NGL pipeline and terminaling fees from higher NGL volumes taken in-kind between periods. Transportation costs increased from $0.58 per Mcfe for the nine months ended September 30, 2020 to $0.68 per Mcfe for the nine months ended September 30, 2021 primarily due to increased utilization on higher tariff pipelines to the Midwest and Gulf Coast between periods.

Production and ad valorem tax expense. Production and ad valorem taxes increased from $71 million for the nine months ended September 30, 2020 to $131 million for the nine months ended September 30, 2021, an increase of $60 million, or 83% primarily due to higher commodity prices between periods and $5 million for the litigation judgment. Production and ad valorem

Table of Contents

taxes as a percentage of natural gas revenues remained consistent at 6% in each of the nine months ended September 30, 2020 and 2021.

Impairment of oil and gas properties. Impairment of oil and gas properties decreased from $156 million for the nine months ended September 30, 2020 to $70 million for the nine months ended September 30, 2021, a decrease of $86 million, or 55%, primarily related to lower impairments of expiring leases between periods. During both periods, we recognized impairments primarily related to expiring leases as well as design and initial costs related to pads we no longer plan to place into service.

Depletion, depreciation, and amortization expense. DD&A expense decreased from $652 million for the nine months ended September 30, 2020 to $564 million for the nine months ended September 30, 2021, a decrease of $88 million, or 13%, primarily as a result of increased proved reserve volumes between periods due to higher commodity prices as well as lower production volumes between periods. DD&A per Mcfe remained relatively consistent at $0.67 per Mcfe and $0.63 per Mcfe during the nine months ended September 30, 2020 and 2021, respectively.

General and administrative expense. General and administrative expense (excluding equity-based compensation expense) increased from $84 million for the nine months ended September 30, 2020 to $94 million for the nine months ended September 30, 2021, an increase of $10 million, or 11%. The increase was primarily due to higher salary and wage expense between periods, which includes our annual incentive program that was significantly reduced during 2020. We had 520 and 506 employees as of September 30, 2020 and 2021, respectively. On a per-unit basis, general and administrative expense excluding equity-based compensation increased from $0.09 per Mcfe during the nine months ended September 30, 2020 to $0.10 per Mcfe during the nine months ended September 30, 2021 as a result of lower production volumes and higher overall costs between periods.

Equity-based compensation expense. Noncash equity-based compensation expense decreased from $17 million for the nine months ended September 30, 2020 to $15 million for the nine months ended September 30, 2021, primarily due to equity award forfeitures, partially offset by new awards granted to employees. When an equity award is forfeited, expense previously recognized for the award is reversed. See Note 9—Equity Based Compensation and Cash Awards to the unaudited condensed consolidated financial statements for more information on equity-based compensation awards.

Marketing Segment

Net marketing expenses decreased from $133 million, or $0.14 per Mcfe, for the nine months ended September 30, 2020 to $65 million, or $0.07 per Mcfe, for the nine months ended September 30, 2021. The decrease was driven by higher marketing volumes and margins that mitigated some of our excess firm transportation expense.

Marketing revenues increased from $202 million for the nine months ended September 30, 2020 to $563 million for the nine months ended September 30, 2021, an increase of $361 million due to increased marketing volumes.

Marketing expenses increased from $335 million for the nine months ended September 30, 2020 to $628 million for the nine months ended September 30, 2021, an increase of $293 million, or 87%. Marketing expenses include firm transportation costs related to current excess firm capacity as well as the cost of third-party purchased gas and NGLs. Firm transportation costs included in the expenses above were $122 million and $81 million for the nine months ended September 30, 2020 and 2021, respectively.

Revenue from the Antero Midstream Corporation segment ~~increased~~decreased from ~~$554 million for the nine months ended September 30, 2019 to~~ $697 million for the nine months ended September 30, 2020 ~~an increase of $143~~to $682 million ~~or 26%, primarily due to~~for the nine months ended September 30, ~~2019 only including Antero Midstream Corporation’s results following the closing~~2021, a decrease of ~~the simplification transactions on March 12, 2019.~~$15 million, or 2%, primarily due to lower fresh water delivery revenue as a result of decreased well completions period-over-period and lower gathering volumes, partially offset by higher compression revenues as a result of increased throughput between periods. Total operating expenses related to the segment ~~increased~~decreased from ~~$774 million for the nine months ended September 30, 2019 to~~ $929 million for the nine months ended September 30, ~~2020. The increase was~~2020 to $255 million for the nine months ended September 30, 2021, primarily due to impairments by Antero Midstream Corporation during the nine months ended September 30, 2020 of $89 million on its freshwater pipelines and equipment and animpairment of goodwill of $575 million. Antero Midstream Corporation’s impairment expense was $2 million for the nine months ended September 30, 2021 due to a lower of ~~$575 million on its goodwill.~~cost or market adjustment for pipe inventory.

Interest expense. Our interest expense decreased from $153 million for the ~~Nine~~nine months ended September 30, ~~2019~~ ~~Compared~~2020 to $138 million for the ~~Nine~~nine months ended September 30, 2021 primarily due to the reduction in debt as a result of our debt repurchases of our unsecured senior notes, paydown of our Prior Credit Facility and increased interest income between periods, partially offset by interest that accrued on the (i) 2026 Convertible Notes, which were issued in August 2020 and (ii) 2026 Notes, 2029 Notes and 2030 Notes, each of which was issued after September 30, 2020.

Impairment of equity investment. AtAs of March 31, 2020, we determined that events and circumstances indicated that the carrying value of our equity method investment in Antero Midstream Corporation had experienced an other-than-temporary decline and we recorded an impairment of $611 million. The fair value of the equity method investment in Antero Midstream Corporation was based on the quoted market share price of Antero Midstream Corporation atas of March 31, 2020.

~~Interest expense.~~ ~~Our interest expense exclusive of interest expense related to Antero Midstream Partners’ indebtedness decreased from $157 million~~ There was no such impairment for the nine months ended September 30, ~~2019~~2021.

Gain (loss) on early extinguishment of debt. During the nine months ended September 30, 2020, we recognized a gain on early extinguishment of debt of $175 million related to ~~$153~~$1.1 billion principal amount of debt that we repurchased at a weighted average discount of 17%. During the nine months ended September 30, 2021, we equitized $206 million aggregate principal amount of our 2026 Convertible Notes in privately negotiated exchange transactions and as a result, we recognized a loss of $61 million which represents the difference between the fair value of the liability component of the 2026 Convertible Notes and the carrying value of such notes. Additionally, during the nine months ended September 30, 2021, we redeemed (i) the remaining balance of $661 million of our 2022 Notes at par, plus accrued and unpaid interest, (ii) the remaining balance of $574 million of our 2023 Notes at par, plus accrued and unpaid interest and (iii) $175 million of our 2026 Notes at a redemption price of 108.375% of par, plus accrued and unpaid interest and recognized a $22 million loss on early extinguishment of debt for such redemptions. See Note 7—Long-Term Debt to the unaudited condensed consolidated financial statements for more information.

Loss on convertible note equitization. During the nine months ended September 30, 2021, we recognized a loss of $51 million for the January Equitization Transactions and the May Equitization Transactions, which represents the consideration paid in excess of the original terms of the 2026 Convertible Notes. See Note 7—Long-Term Debt to the unaudited condensed consolidated financial statements for more information.

Transaction expense. Transaction expense decreased from $7 million for the nine months ended September 30, 2020 ~~primarily due~~ to the reduction in debt as a result of our debt repurchases of our unsecured senior notes at prices below their stated value, partially offset by interest that accrued on the newly issued 2026 Convertible Notes.

~~Consolidated interest expense decreased from $174~~$3 million for the nine months ended September 30, ~~2019 to $153~~2021, a decreased of $4 million or 53%. Transaction expense for the nine months ended September 30, 2020 a decrease of $21 million, or 12%. During the nine months ended September 30, 2019, interest related to Antero Midstream Partners’ debt through March 12, 2019 is included in consolidated interest expense. Interest expense includes approximately $8.3 million and $8.0 million of non-cash amortization of deferred financing costs for the nine months ended September 30, 2019 and 2020, respectively.

~~Transaction expense.~~ ~~We incurred transaction expense of $7 million in the nine months ended September 30, 2020 and did not incur comparable costs in the nine months ended September 30, 2019. These expenses~~ included legal and transaction fees associated with the sale of our ~~ORRI~~overriding royalty interest and the creation of Martica, as well as the VPP transaction. For the nine months ended September 30, 2021, transaction expense included legal and transaction fees associated with the drilling partnership. See Note 4—3—Transactions to the unaudited condensed consolidated financial statements ~~included elsewhere in this Quarterly Report on Form 10-Q~~ for more information on these transactions.

The decrease was primarily due to ~~commodity price decreases for the nine months ended September 30, 2020.~~lower loss before income taxes between periods.

Capital Resources and Liquidity

Sources and Uses of Cash

Our primary sources of liquidity have been through net cash provided by operating activities including ~~proceeds from derivatives,~~ borrowings under the Prior Credit Facility, issuances of debt and equity securities, ~~distributions/dividends from unconsolidated affiliates~~ and ~~proceeds~~additional contributions from our asset ~~sale~~sales program, including ~~the sale of the overriding royalty interest.~~our drilling partnership. Our primary use of cash has been for the exploration, development, and acquisition of oil and natural gas properties. As we develop our reserves, we continually monitor what capital resources, including equity and debt financings, are available to meet our future financial obligations, planned capital expenditure activities, and liquidity requirements. Our future success in growing our proved reserves and production will be highly dependent on net cash provided by operating activities and the capital resources available to us.

~~During~~ For information about the ~~nine months ended September 30, 2020, we repurchased shares~~impacts of COVID-19 on our ~~common stock under our share repurchase program that expired March 31, 2020. We repurchased~~capital resources and ~~retired 28,193,237 common shares at a weighted average price per share of $1.54 for approximately $43 million during the nine months ended September 30, 2020.~~

~~Table of Contents~~

We may also seek to retire or purchase our outstanding debt securities from time to time through cash purchases, in open market purchases, privately negotiated transactions or otherwise. Any such repurchases will depend on prevailing market conditions, our liquidity, requirements, contractual restrictions and other factors. During the three and nine months ended September 30, 2020, we repurchased $461 million and $1.1 billion, respectively, principal amount of debt at a weighted average discount of 13% and 17%, respectively, which purchases included a portion of the 2021 Notes, 2022 Notes, 2023 Notes and 2025 Notes. Repurchases of the principal amount of debt during the three and nine months ended September 30, 2020 include repurchases of $367 million on the 2021 Notes, 2022 Notes and 2023 Notes through previously disclosed tender offers at a weighted average discount of 10%. These repurchases, at a discount, have resulted in a net reduction in total debt outstanding and interest expense.see “—COVID-19 Pandemic.”

AsBased on strip prices as of September 30, ~~2020,~~2021, we believe that ~~funds from~~net cash provided by operating ~~cash flows,~~activities, distributions from unconsolidated ~~affiliates,~~affiliate, available borrowings under the Credit Facility, or capital market transactions and the effects of the drilling partnership will be sufficient to meet our cash requirements, including normal operating needs, debt service obligations, capital expenditures, and commitments and contingencies for at least the next 12 months.

2021 Capital Budget and Capital Spending

On February 17, 2021, we announced our net capital budget for 2021 is $635 million, which includes: $590 million for drilling and completion and $45 million for leasehold expenditures. We do not include acquisitions in our capital budget. We periodically review our capital expenditures and adjust our budget and its allocation based on commodity prices, takeaway constraints, operating cash flow and liquidity, and on July 28, 2021, we announced a $22.5 million increase for our leasehold expenditures for 2021 to reflect accelerated leasing activity focused on organically expanding our core liquids rich inventory. As a result, our total net capital budget for 2021 was revised to $657.5 million.

For the nine months ended September 30, 2021, our total consolidated capital expenditures, which excludes QL’s working interest share of such costs, were approximately $542 million, including drilling and completion costs of $475 million, leasehold acquisitions of $48 million, and other capital expenditures of $19 million.

Our 2021 Notes are due November 1, 2021 and our Credit Facility will become due 91 days prior to that date, or on August 1, 2021, if the 2021 Notes are not repaid prior to August 1, 2021. Under our business plan, we intend to extinguish the 2021 Notes prior to August 1, 2021 with proceeds from our asset sales program, cash flow from operations and available borrowings under the Credit Facility. Consequently, we have classified our Credit Facility as long-term debt. The classification of our Credit Facility does not impact any of our financial covenants.

For more information on our outstanding indebtedness, see Note 8—Long Term Debt to the unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

Effective March 13, 2019, the Company's cash flows include only the operating, investing~~2020 and financing activities related to Antero. Therefore, the cash flows for the nine months ended September 30, 2019 may not be representative of our expected future cash flows. See Note 3—Deconsolidation of Antero Midstream Partners LP to the unaudited condensed consolidated financial statements for more information.

~~Cash Flows Provided by Operating Activities~~

2021, respectively. Net cash provided by operating activities ~~was $956 million and $493 million for the nine months ended September 30, 2019 and 2020, respectively. Cash flow from operations decreased~~increased primarily due to ~~decreases~~increases in commodity prices both before and after the effects of settled commodity derivatives, ~~and~~decreased net marketing expense as well as decreased cash utilized for working capital, partially offset by increases in gathering, compression ~~processing,~~ and transportation ~~costs.~~costs and production and ad valorem taxes between periods.

Our net operating cash flows are sensitive to many variables, the most significant of which is the volatility of natural gas, NGLs, and oil prices, as well as volatility in the cash flows attributable to settlement of our commodity derivatives. Prices for natural gas, NGLs, and oil are primarily determined by prevailing market conditions. Regional and worldwide economic activity, weather, infrastructure capacity to reach markets, storage capacity and other variables influence the market conditions for these products. For example, the impact of the COVID-19 outbreak has reduced domestic and international demand for natural gas, NGLs, and oil. These factors are beyond our control and are difficult to predict.

~~Cash Flows Used in Investing Activities~~

Investing Activities.Cash flows used in investing activities ~~decreased~~increased from ~~$825 million for the nine months ended September 30, 2019 to~~ $384 million for the nine months ended September 30, 2020 ~~primarily due~~ to ~~a decrease in capital expenditures of $307~~$505 million ~~during the~~

~~In addition, the nine months ended September 30, 2019 included Antero Midstream Partners’ investments~~2020, partially offset by a decrease in ~~joint ventures of $25 million and~~ capital expenditures ~~for water handling and treatment systems and gas gathering and compression systems~~ of $73 million. Due to the deconsolidation of Antero Midstream Partners on March 12, 2019, cash flows used in investing activities for the nine months ended September 30, 2020 do not include costs attributable to Antero Midstream Partner’s investing activity. See Note 3—Deconsolidation of Antero Midstream Partners LP to the unaudited condensed consolidated financial statements.

~~Total capital expenditures for oil and gas properties decreased from $1.0 billion during the nine months ended September 30, 2019 to $726~~$215 million during the nine months ended September 30, ~~2020 primarily due~~2021 as compared to ~~a decrease~~the same period in ~~drilling and completion activity, increased drilling and completion efficiencies and service cost deflation.~~2020.

Our drilling and completion capital budget for 2020 has been reduced to $750 million from $1.15 billion. Our capital budget may be adjusted as business conditions warrant as the amount, timing, and allocation of capital expenditures is largely discretionary and within our control. If natural gas, NGLs, and oil prices decline to levels that do not generate an acceptable level of corporate returns, or costs increase to levels that do not generate an acceptable level of corporate returns, we may defer a significant portion of our budgeted capital expenditures until later periods to achieve the desired balance between sources and uses of liquidity, and to prioritize capital projects that we believe have the highest expected returns and potential to generate near-term cash flows. We routinely monitor and adjust our capital expenditures in response to changes in commodity prices, availability of financing, drilling and acquisition costs, industry conditions, the timing of regulatory approvals, the availability of rigs, the relative success in drilling activities, contractual obligations, internally generated cash flows, and other factors both within and outside our control.

We may, from time to time, seek to retire or purchase our outstanding debt through cash purchases and/or exchanges for equity securities, in open market purchases, privately negotiated transactions, or otherwise. Such repurchases, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions, and other factors. The amounts involved could be material.

Includes outstanding principal amounts as of September 30, 2020. This table does not include future commitment fees, interest expense, or other fees on our Credit Facility because they are floating rate instruments and we cannot determine with accuracy the timing of future loan advances, repayments, or future interest rates to be charged. The maturity date of the Credit Facility is the earlier of (i) October 26, 2022 and (ii) the date that is 91 days prior to the earliest stated redemption of any series of Antero’s senior notes then outstanding, which is August 1, 2021 if the 2021 Notes are not repaid prior to such date. Under our business plan, we intend to extinguish the 2021 Notes prior to August 1, 2021 with proceeds from our asset sales program, cash flow from operations and available borrowings under our Credit Facility. Consequently, we have classified our Credit Facility as long-term debt.

Non-GAAP Financial Measures

Adjusted EBITDAX is a non-GAAP financial measure that we define as net income (loss), including noncontrolling interests, before interest expense, interest income, gains or losses from commodity derivatives, ~~and marketing derivatives,~~ amortization of deferred revenue, gain on sale of assets but including net cash receipts or payments on derivative instruments included in derivative gains or losses other than proceeds from and payments for derivative monetizations, income taxes, impairments, depletion, depreciation, amortization, and accretion, exploration expense, equity-based compensation, gain ~~or loss~~(loss) on early extinguishment of debt, contract termination and rig stacking costs, ~~loss on sale of equity investment shares,~~ equity in earnings ~~or loss~~(loss) of unconsolidated ~~affiliates, water earnout, simplification~~affiliate, transaction fees ~~gain or~~and loss on ~~sale of assets and Antero Midstream Partners related adjustments.~~

~~Through March 12, 2019, the financial results of Antero Midstream~~ ~~Partners were included in our consolidated results. Effective March 13, 2019, we no longer consolidate Antero~~ ~~Midstream~~ Partners and account for our interest in Antero Midstream using the equity method of accounting. See Note 6—Equity Method Investments to the unaudited condensed consolidated financial statements for more information on our equity investments. Adjusted EBITDAX includes distributions received with respect to limited partner interests in Antero ~~Midstream Partners common units through March 12, 2019.~~convertible note equitization.

Adjusted EBITDAX as used and defined by us, may not be comparable to similarly titled measures employed by other companies and is not a measure of performance calculated in accordance with GAAP. Adjusted EBITDAX should not be considered in isolation or as a substitute for operating income or loss, net income or loss, cash flows provided by operating, investing, and financing activities, or other income or cash flow statement data prepared in accordance with GAAP. Adjusted EBITDAX provides no information regarding our capital structure, borrowings, interest costs, capital expenditures, working capital movement, or tax position. Adjusted EBITDAX does not represent funds available for discretionary use because those funds may be required for debt service, capital expenditures, working capital, income taxes, exploration expenses, and other commitments and obligations. However, our management team believes Adjusted EBITDAX is useful to an investor in evaluating our financial performance because this measure:

●

is widely used by investors in the oil and natural gas industry to measure operating performance without regard to items excluded from the calculation of such term, which may vary substantially from company to company depending upon accounting methods and the book value of assets, capital structure and the method by which assets were acquired, among other factors;

●

helps investors to more meaningfully evaluate and compare the results of our operations from period to period by removing the effect of our capital and legal structure from our operating structure;

●

is used by our management team for various purposes, including as a measure of our operating performance, in presentations to our Board of Directors, and as a basis for strategic planning and forecasting; and

●

is used by our Board of Directors as a performance measure in determining executive compensation.

There are significant limitations to using Adjusted EBITDAX as a measure of performance, including the inability to analyze the effects of certain recurring and non-recurring items that materially affect our net income or loss, the lack of comparability of results of operations of different companies, and the different methods of calculating Adjusted EBITDAX reported by different companies.

The following table represents a reconciliation of our net income (loss), including noncontrolling interest, to Adjusted EBITDAX and a reconciliation of our Adjusted EBITDAX to net cash provided by operating activities per our unaudited condensed consolidated statements of cash flows, in each case, for the three and nine months ended September 30, ~~2019~~2020 and 2020. Adjusted EBITDAX excludes the results of Antero Midstream Partners in order to provide comparability with the current structure of Antero Resources as effective March 13, 2019, we no longer consolidate Antero Midstream Partners results.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations are based upon our unaudited condensed consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of our unaudited condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. Certain accounting policies involve judgments and uncertainties to such an extent that there is reasonable likelihood that materially different amounts could have been reported under different conditions, or if different assumptions had been used. We evaluate our estimates and assumptions on a regular basis. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates and assumptions used in preparation of our unaudited condensed consolidated financial statements. Our more significant accounting policies and estimates include the successful efforts method of accounting for our production activities, estimates of natural gas, NGLs, and oil reserve quantities and standardized measures of future cash flows, and impairment of proved properties. We provide an expanded discussion of our more significant accounting policies,

Table of Contents

estimates and judgments in the ~~2019~~2020 Form 10-K. We believe these accounting policies reflect our more significant estimates and assumptions used in the preparation of our unaudited condensed consolidated financial statements. Also, see Note 2—Summary of Significant Accounting Policies to the consolidated financial statements, included in the ~~2019~~2020 Form 10-K, for a discussion of additional accounting policies and estimates made by management.

We evaluate the carrying amount of our proved natural gas, NGLs, and oil properties for impairment for the Utica and Marcellus Shale properties, by property, when events or changes in circumstances indicate that a property’s carrying amount may not be recoverable. Under GAAP for successful efforts accounting, if the carrying amount exceeds the estimated undiscounted future net cash flows (measured using future prices), we estimate the fair value of our proved properties and record an impairment charge for any excess of the carrying amount of the properties over the estimated fair value of the properties.

The estimated future net cash flows have been impacted by the COVID-19 pandemic and the decision in March 2020 by Saudi Arabia to reduce the price at which it sells oil and announcing plans to increase production. These events have caused, and continue to cause, significant volatility in future prices which are used in this evaluation. Based on future prices as of September 30, ~~2020,~~2021, the estimated undiscounted future net cash flows exceeded the carrying amount and no further evaluation was required. We have not recorded any impairment expenses associated with our proved properties during the three and nine months ended September 30, ~~2019~~2020 and ~~2020. We recorded an impairment charge of $881 million related to the Utica Shale properties on September 30, 2019.~~2021.

Estimated undiscounted future net cash flows are very sensitive to commodity price swings at current commodity price levels and a relatively small decline in prices could result in the carrying amount exceeding the estimated undiscounted future net cash flows at the end of a future reporting period, which would require us to further evaluate if an impairment charge would be necessary. If future prices decline ~~further~~ from September 30, ~~2020,~~2021, the fair value of our properties may be below their carrying amounts and an impairment charge may be necessary. We are unable, however, to predict future commodity prices with any reasonable certainty.

New Accounting Pronouncements

Risk Factors) that require separate accounting for conversion features that is currently being applied~~Policies to the ~~2026 Convertible Notes, and instead, allows the debt instrument and conversion features to be accounted~~unaudited condensed consolidated financial statements for ~~as a single debt instrument. The~~information on new ~~standard becomes effective on January 1, 2022, and early adoption is permitted. We are~~ ~~evaluating our plans for adoption, including the adoption date and transition method.~~

Upon adoption of this new standard, we expect to reclassify $62 million, net of deferred income taxes and equity issuance costs, to long-term debt and deferred income tax liability, as applicable, from stockholders’ equity. Additionally, annual interest expense for the 2026 Convertible Notes will be based on an effective interest rate of 4.8% as compared to 11.7% for the three and nine months ended September 30, 2020 in the statement of operations and the weighted average diluted shares outstanding will increase from zero as of September 30, 2020 under the treasury-stock method to 66 million under the if-converted method. We do ~~not believe that adoption of the standard will impact our operational strategies or growth prospects.~~accounting pronouncements.

Off-Balance Sheet Arrangements

As of September 30, ~~2020,~~2021, we did not have any off balance sheet arrangements other than contractual commitments for firm transportation, gas processing and fractionation, gathering, and compression services and land payment obligations. See ~~“—Debt Agreements and Contractual Obligations—Contractual Obligations”~~Note 13—Commitments to the unaudited condensed consolidated financial statements for ~~our commitments under these agreements.~~further information on off balance sheet arrangements.

Item 3. Quantitative and Qualitative Disclosures About Market ~~Risk.~~Risk

The primary objective of the following information is to provide forward-looking quantitative and qualitative information about our potential exposure to market risk. The term “market risk” refers to the risk of loss arising from adverse changes in natural gas, NGLs, and oil prices, as well as interest rates. These disclosures are not meant to be precise indicators of expected future losses, but rather indicators of reasonably possible losses. This forward-looking information provides indicators of how we view and manage our ongoing market risk exposures.

Commodity Hedging Activities

Our primary market risk exposure is in the price we receive for our natural gas, NGLs, and oil production. Pricing is primarily driven by spot regional market prices applicable to our U.S. natural gas production and the prevailing worldwide price for oil. Pricing for natural gas, NGLs, and oil has, historically, been volatile and unpredictable, and we expect this volatility to continue in the future. The prices we receive for our production depend on many factors outside of our control, including volatility in the differences between commodity prices at sales points and the applicable index price.

To mitigate some of the potential negative impact on our cash flows caused by changes in commodity prices, we enter into financial derivative instruments for a portion of our natural gas, NGLs, and oil production when management believes that favorable future prices can be secured.

Our financial hedging activities are intended to support natural gas, NGLs, and oil prices at targeted levels and to manage our exposure to natural gas, NGLs, and oil price fluctuations. These contracts may include commodity price swaps whereby we will receive a fixed price and pay a variable market price to the contract counterparty, collars that set a floor and ceiling price for the hedged production, basis differential swaps or embedded options. These contracts are financial instruments and do not require or allow for physical delivery of the hedged commodity. As of September 30, ~~2020,~~2021, our commodity derivatives included fixed price swaps and basis differential swaps at index-based pricing.

Table of Contents

As of September 30, ~~2020,~~2021, we had in place natural gas swaps covering portions of our projected production through 2023. Our commodity hedge position as of September 30, ~~2020~~2021 is summarized in Note ~~12—~~11—Derivative Instruments to our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q. Under the Credit Facility, we are permitted to hedge up to 75% of our projected production for the next 60 months. We may enter into hedge contracts with a term greater than 60 months, and for no longer than 72 months, for up to 65% of our estimated production. Based on our production and our fixed price swap contracts and embedded put option that settled during the nine months ended September 30, ~~2020,~~2021, our revenues would have decreased by approximately ~~$31~~$22 million for each $0.10 decrease per MMBtu in natural gas prices and $1.00 decrease per Bbl in oil and NGLs prices, excluding the effects of changes in the fair value of our derivative positions which remain open as of September 30, ~~2020.~~2021.

All derivative instruments, other than those that meet the normal purchase and normal sale scope exception or other derivative scope exceptions, are recorded at fair market value in accordance with GAAP and are included in our consolidated balance sheets as assets or liabilities. The fair values of our derivative instruments are adjusted for non-performance risk. Because we do not designate these derivatives as accounting hedges, they do not receive hedge accounting treatment; therefore, all mark-to-market gains or losses, as well as cash receipts or payments on settled derivative instruments, are recognized in our statements of operations. We present total gains or losses on commodity derivatives (for both settled derivatives and derivative positions which remain open) within operating revenues as “Commodity derivative fair value gains (losses).”

Mark-to-market adjustments of derivative instruments cause earnings volatility but have no cash flow impact relative to changes in market prices until the derivative contracts are settled or monetized prior to settlement. We expect continued volatility in the fair value of our derivative instruments. Our cash flows are only impacted when the associated derivative contracts are settled or monetized by making or receiving payments to or from the counterparty. As of September 30, ~~2020,~~2021, the estimated fair value of our commodity derivative instruments was a net liability of ~~$130 million~~$1.7 billion comprised of current and noncurrent assets and liabilities. AtAs of December 31, ~~2019,~~2020, the estimated fair value of our commodity derivative instruments was a net asset of ~~$746~~$22 million comprised of current and noncurrent assets and liabilities.

By removing price volatility from a portion of our expected production through December 2023, we have mitigated, but not eliminated, the potential negative effects of changing prices on our operating cash flows for those periods. While mitigating the negative effects of falling commodity prices, these derivative contracts also limit the benefits we would receive from increases in commodity prices above the fixed hedge prices.

~~Table of Contents~~

Counterparty and Customer Credit Risk

Our principal exposures to credit risk are through receivables resulting from the following: commodity derivative contracts ($~~127~~15 million as of September 30, ~~2020)~~2021); and the sale of our natural gas, NGLs and oil production ($~~301~~556 million as of September 30, ~~2020)~~2021), which we market to energy companies, end users, and refineries.

By using derivative instruments that are not traded on an exchange to hedge exposures to changes in commodity prices, we expose ourselves to the credit risk of our counterparties. Credit risk is the potential failure of a counterparty to perform under the terms of a derivative contract. When the fair value of a derivative contract is positive, the counterparty is expected to owe us, which creates credit risk. To minimize the credit risk in derivative instruments, it is our policy to enter into derivative contracts only with counterparties that are creditworthy financial institutions that management deems to be competent and competitive market makers. The creditworthiness of our counterparties is subject to periodic review. We have commodity hedges in place with 1617 different counterparties, 13 of which are lenders under our Prior Credit Facility. ~~The fair value of the net liability of our commodity derivative contracts of approximately $130 million as~~As of September 30, ~~2020 included the following~~2021, we did not have any derivative assets by bank counterparty: Canadian Imperial Bank of Commerce - $29 million; Morgan Stanley - $17 million; Scotiabank - $14 million; BNP Paribas - $5 million; PNC - $3 million; TD Energy - $3 million; Natixis - $2 million and Truist - $1 million.counterparties under our Prior Credit Facility. The estimated fair value of our commodity derivative assets has been risk-adjusted using a discount rate based upon the counterparties’ respective published credit default swap rates (if available, or if not available, a discount rate based on the applicable Reuters bond rating) as of September 30, ~~2020~~2021 for each of the European and American banks. We believe that all of these institutions, currently, are acceptable credit risks. Other than as provided by the Prior Credit Facility, we are not required to provide credit support or collateral to any of our counterparties under our derivative contracts, nor are they required to provide credit support to us. As of September 30, ~~2020,~~2021, we did not have any past-due receivables from, or payables to, any of the counterparties to our derivative contracts.

We are also subject to credit risk due to the concentration of our receivables from several significant customers for sales of natural gas, NGLs, and oil. We generally do not require our customers to post collateral. The inability or failure of our significant customers to meet their obligations to us, or their insolvency or liquidation, may adversely affect our financial results.

Interest Rate Risks

Our primary exposure to interest rate risk results from outstanding borrowings under the Prior Credit Facility, which has a floating interest rate. The average annualized interest rate incurred on the Prior Credit Facility during the nine months ended September 30, ~~2020~~2021 was approximately ~~3.23%~~4.18%. We estimate that a 1.0% increase in the applicable average interest rates for the nine months ended September 30, ~~2020~~2021 would have resulted in an estimated ~~$6.3~~$1.5 million increase in interest expense.

As required by Rule 13a-15(b) under the Exchange Act, we have evaluated, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report on Form 10-Q. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosures and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Based upon that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of September 30, ~~2020~~2021 at a level of reasonable assurance.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended September 30, ~~2020~~2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

The information required by this item is included in Note ~~15—~~14—Contingencies to our unaudited condensed consolidated financial statements and is incorporated herein.

Item 1A. Risk ~~Factors.~~Factors

We are subject to certain risks and hazards due to the nature of the business activities we conduct. For a discussion of these risks, see “Item 1A. Risk Factors” in the ~~2019~~2020 Form ~~10-K and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020 in addition to the risks described below. Other than as described below, there~~10-K. There have been no material changes to the risks described in ~~the 2019 Form 10-K and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020.~~such report. We may experience additional risks and uncertainties not currently known to us. Furthermore, as a result of developments occurring in the future, conditions that we currently deem to be immaterial may also materially and adversely affect us. Any such risk, in addition to those described below, in the 2019 Form 10-K and in the Quarterly Report on Form 10-Q for the quarter ended March 31, 2020, may materially and adversely affect our business, financial condition, cash flows and results of operations.

~~The accounting method for convertible debt securities that may be settled in cash, such as the 2026 Convertible Notes, could have a material effect on our reported financial results.~~

Under Accounting Standards Codification 470-20, Debt with Conversion and Other Options (“ASC 470-20”), an entity must separately account for the liability and equity components of the convertible debt instruments (such as the 2026 Convertible Notes) that may be settled entirely or partially in cash upon conversion in a manner that reflects the issuer’s economic interest cost. The effect of ASC 470-20 on the accounting for the 2026 Convertible Notes is that the equity component is required to be included in the additional paid-in capital section of stockholders’ equity on our consolidated balance sheet at the issuance date and the value of the equity component would be treated as a debt discount for purposes of accounting for the debt component of the 2026 Convertible Notes. As a result, we will be required to record a greater amount of non-cash interest expense as a result of the amortization of the discounted carrying value of the 2026 Convertible Notes to their face amount over the term of the 2026 Convertible Notes. We will report larger net losses (or lower net income) in our financial results because ASC 470-20 will require interest to include both the amortization of the debt discount and the instrument’s non-convertible coupon interest rate, which could adversely affect our reported earnings and financial condition.

In addition, under certain circumstances, convertible debt instruments (such as the 2026 Convertible Notes) that may be settled entirely or partly in cash may be accounted for utilizing the treasury stock method, the effect of which is that the shares issuable upon conversion of such 2026 Convertible Notes are not included in the calculation of diluted earnings per share except to the extent that the conversion value of such 2026 Convertible Notes exceeds their principal amount. Under the treasury stock method, for diluted earnings per share purposes, the transaction is accounted for as if the number of shares of common stock that would be necessary to settle such excess, if we elected to settle such excess in shares, are issued. We cannot be sure that the accounting standards in the future will continue to permit the use of the treasury stock method. If we are unable or otherwise elect not to use the treasury stock method in accounting for the shares issuable upon conversion of the 2026 Convertible Notes, then our diluted earnings per share could be adversely affected. For example, in August 2020, the Financial Accounting Standards Board issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40) to amend current accounting standards to eliminate the treasury stock method for convertible instruments and instead require application of the “if-converted” method. Under that method, if it is adopted, diluted earnings per share would generally be calculated assuming that all the notes were converted solely into shares of common stock at the beginning of the reporting period, unless the result would be anti-dilutive. The application of the if-converted method may change previously reported per share results.

Conversion of the 2026 Convertible Notes may dilute the ownership interest of existing stockholders, including holders who had previously converted their 2026 Convertible Notes, or may otherwise depress the price of our common stock.

The conversion of some or all of the 2026 Convertible Notes will dilute the ownership interests of existing stockholders if we deliver shares of our common stock upon conversion of any of the 2026 Convertible Notes. The 2026 Convertible Notes may become convertible at the option of holders prior to their scheduled terms under certain circumstances. Any sales in the public market of the common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. In addition, the existence of the 2026 Convertible Notes may encourage short selling by market participants because the conversion of the 2026

~~Table of Contents~~

~~Convertible Notes could be used to satisfy short positions, or anticipated conversion of the 2026 Convertible Notes into shares of our common stock could depress the price of our common stock.~~

We may be unable to raise the funds necessary to repurchase the 2026 Convertible Notes for cash following a fundamental change, or to pay any cash amounts due upon conversion, and our other indebtedness may limit our ability to repurchase the 2026 Convertible Notes or pay cash upon their conversion.

Holders of our 2026 Convertible Notes may, subject to a limited exception, require us to repurchase their 2026 Convertible Notes following a fundamental change at a cash repurchase price generally equal to 100% of the principal amount of the 2026 Convertible Notes to be repurchased, plus accrued and unpaid interest, if any. In addition, upon conversion, we will satisfy part or all of our conversion obligation in cash unless we elect to settle conversions solely in shares of our common stock. We may not have enough available cash or be able to obtain financing at the time we are required to repurchase the 2026 Convertible Notes or pay the cash amounts due upon conversion. In addition, applicable law, regulatory authorities and the agreements governing our other indebtedness, may restrict our ability to repurchase the 2026 Convertible Notes or pay the cash amounts due upon conversion. Our inability to satisfy our obligations under the 2026 Convertible Notes could affect the trading price of our common stock.

Our failure to repurchase the 2026 Convertible Notes or to pay the cash amounts due upon conversion when required will constitute a default under the indenture governing the 2026 Convertible Notes. A default under this indenture or the occurrence of the fundamental change itself could also lead to a default under agreements governing our other indebtedness, which may result in that other indebtedness becoming immediately payable in full. We may not have sufficient funds to satisfy all amounts due under the other indebtedness and the 2026 Convertible Notes.

~~Provisions of our 2026 Convertible Notes could delay or prevent an otherwise beneficial takeover of us.~~

Certain provisions of our 2026 Convertible Notes and the indenture governing such notes could make a third-party attempt to acquire us more difficult or expensive. For example, if a takeover constitutes a “Fundamental Change” (as defined in the indenture governing such notes), then holders of our 2026 Convertible Notes will have the right to require us to repurchase their 2026 Convertible Notes for cash. In addition, if a takeover constitutes a “Make-Whole Fundamental Change” (as defined in such indenture), then we may be required to temporarily increase the conversion rate. In either case, and in other cases, our obligations under the 2026 Convertible Notes and the indenture governing such notes could increase the cost of acquiring us or otherwise discourage a third party from acquiring us, including in a transaction that holders of our 2026 Convertible Notes or holders of our common stock may view as favorable.
