NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1.    Summary of Significant Accounting Policies

General. The condensed consolidated financial statements of EOG Resources, Inc., together with its subsidiaries (collectively, EOG), included herein have been prepared by management without audit pursuant to the rules and regulations of the United States Securities and Exchange Commission (SEC). Accordingly, they reflect all normal recurring adjustments which are, in the opinion of management, necessary for a fair presentation of the financial results for the interim periods presented. Certain information and notes normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations. However, management believes that the disclosures included either on the face of the financial statements or in these notes are sufficient to make the interim information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in EOG's Annual Report on Form 10-K for the year ended December 31, 2020, filed on February 25, 2021 (EOG's 2020 Annual Report).

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The operating results for the three and nine months ended September 30, 2021, are not necessarily indicative of the results to be expected for the full year.

Effective January 1, 2021, EOG adopted the provisions of Accounting Standards Update (ASU) 2019-12, "Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes" (ASU 2019-12). ASU 2019-12 amends certain aspects of accounting for income taxes, including the removal of specific exceptions within existing U.S. GAAP related to the incremental approach for intraperiod tax allocation and updates to the general methodology for calculating income taxes in interim periods, among other changes. ASU 2019-12 also requires an entity to reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date, among other requirements. The effects of ASU 2019-12 applicable to EOG were all required on a prospective basis. There was no impact upon adoption of ASU 2019-12 to EOG's consolidated financial statements or related disclosures.

Recently Issued Accounting Standards. In March 2020, the Financial Accounting Standards Board (FASB) issued ASU 2020-04, "Reference Rate Reform (Topic 848)" (ASU 2020-04), which provides optional expedients and exceptions for accounting treatment of contracts which are affected by the anticipated discontinuation of the London InterBank Offered Rate (LIBOR) and other rates resulting from rate reform. Contract terms that are modified due to the replacement of a reference rate are not required to be remeasured or reassessed under relevant accounting standards. Early adoption is permitted. ASU 2020-04 covers certain contracts which reference these rates and that are entered into on or before December 31, 2022. EOG is evaluating the provisions of ASU 2020-04 and has not determined the full impact on its consolidated financial statements and related disclosures related to its $2.0 billion senior unsecured Revolving Credit Agreement.

2.    Stock-Based Compensation

As more fully discussed in Note 7 to the Consolidated Financial Statements included in EOG's 2020 Annual Report, EOG maintains various stock-based compensation plans. Stock-based compensation expense is included on the Condensed Consolidated Statements of Income (Loss) and Comprehensive Income (Loss) based upon the job function of the employees receiving the grants as follows (in millions):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
Lease and Well	$	11	$	9	$	36	$	39
Gathering and Processing Costs	1		—		2		1
Exploration Costs	4		1		15		15
General and Administrative	35		23		64		58
Total	$	51	$	33	$	117	$	113

The Amended and Restated EOG Resources, Inc. 2008 Omnibus Equity Compensation Plan (2008 Plan) provided for grants of stock options, stock-settled stock appreciation rights (SARs), restricted stock and restricted stock units, performance units and other stock-based awards.

EOG's stockholders approved the EOG Resources, Inc. 2021 Omnibus Equity Compensation Plan (2021 Plan) at the 2021 Annual Meeting of Stockholders. Therefore, no further grants were made from the 2008 Plan from and after the April 29, 2021 effective date of the 2021 Plan. The 2021 Plan provides for grants of stock options, SARs, restricted stock and restricted stock units, restricted stock units with performance-based conditions (together with the performance units granted under the 2008 Plan, "Performance Units") and other stock-based awards, up to an aggregate maximum of 20 million shares of common stock, plus any shares that are subject to outstanding awards under the 2008 Plan as of April 29, 2021, that are subsequently canceled, forfeited, expire or are otherwise not issued or are settled in cash. Under the 2021 Plan, grants may be made to employees and non-employee members of EOG's Board of Directors (Board). EOG's policy is to issue shares related to 2021 Plan grants from previously authorized unissued shares or treasury shares to the extent treasury shares are available.

At September 30, 2021, approximately 17 million shares of common stock remained available for grant under the 2021 Plan.

Stock Options and Stock-Settled Stock Appreciation Rights and Employee Stock Purchase Plan. The fair value of stock option grants and SAR grants is estimated using the Hull-White II binomial option pricing model. The fair value of Employee Stock Purchase Plan (ESPP) grants is estimated using the Black-Scholes-Merton model. Stock-based compensation expense related to stock option, SAR and ESPP grants totaled $20 million and $23 million during the three months ended September 30, 2021 and 2020, respectively, and $39 million and $52 million during the nine months ended September 30, 2021 and 2020, respectively.

Weighted average fair values and valuation assumptions used to value stock option, SAR and ESPP grants during the nine-month periods ended September 30, 2021 and 2020 are as follows:

	Stock Options/SARs						ESPP
	Nine Months Ended September 30,						Nine Months Ended September 30,
	2021			2020			2021			2020
Weighted Average Fair Value of Grants	$	24.92		$	11.06		$	18.15		$	18.96
Expected Volatility	42.24		%	44.46		%	51.23		%	55.53		%
Risk-Free Interest Rate	0.50		%	0.21		%	0.07		%	0.83		%
Dividend Yield	2.25		%	3.27		%	2.88		%	2.35		%
Expected Life	5.2 years			5.2 years			0.5 years			0.5 years

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

(Unaudited)

Expected volatility is based on an equal weighting of historical volatility and implied volatility from traded options in EOG's common stock. The risk-free interest rate is based upon United States Treasury yields in effect at the time of grant. The expected life is based upon historical experience and contractual terms of stock option, SAR and ESPP grants.

The following table sets forth stock option and SAR transactions for the nine-month periods ended September 30, 2021 and 2020 (stock options and SARs in thousands):

	Nine Months Ended September 30, 2021			Nine Months Ended September 30, 2020
	Number of Stock Options/SARs	Weighted Average Exercise Price		Number of Stock Options/SARs	Weighted Average Exercise Price
Outstanding at January 1	10,186	$	84.08	9,395	$	94.53
Granted	1,976	81.66		1,993	37.62
Exercised (1)	(448)	64.18		(23)	69.59
Forfeited	(984)	98.64		(1,077)	88.54
Outstanding at September 30 (2)	10,730	$	83.13	10,288	$	84.19
Vested or Expected to Vest (3)	10,407	$	83.65	9,963	$	84.86
Exercisable at September 30 (4)	6,906	$	92.39	6,389	$	96.53

(1)The total intrinsic value of stock options/SARs exercised during the nine months ended September 30, 2021 and 2020 was $8 million and $0.4 million, respectively. The intrinsic value is based upon the difference between the market price of EOG's common stock on the date of exercise and the exercise price of the stock options/SARs.

Performance Units. EOG grants Performance Units annually to its executive officers without cost to them. As more fully discussed in the grant agreements, the performance metric applicable to the Performance Units is EOG's total shareholder return over a three-year performance period relative to the total shareholder return of a designated group of peer companies (Performance Period). Upon the application of the performance multiple at the completion of the Performance Period, a minimum of 0% and a maximum of 200% of the Performance Units granted could be outstanding. The fair value of the Performance Units is estimated using a Monte Carlo simulation. Stock-based compensation expense related to the Performance Unit grants totaled $11 million and $6 million for the three months ended September 30, 2021 and 2020, respectively, and $13 million and $8 million for the nine months ended September 30, 2021 and 2020, respectively.

8.    Commitments and Contingencies

There are currently various suits and claims pending against EOG that have arisen in the ordinary course of EOG's business, including contract disputes, personal injury and property damage claims and title disputes. While the ultimate outcome and impact on EOG cannot be predicted, management believes that the resolution of these suits and claims will not, individually or in the aggregate, have a material adverse effect on EOG's consolidated financial position, results of operations or cash flow. EOG records reserves for contingencies when information available indicates that a loss is probable and the amount of the loss can be reasonably estimated.

9.    Pension and Postretirement Benefits

Pension Plans. EOG has a defined contribution pension plan in place for most of its employees in the United States. EOG's contributions to the pension plan are based on various percentages of compensation and, in some instances, are based upon the amount of the employees' contributions. EOG's total costs recognized for the pension plan were $36 million and $31 million for the nine months ended September 30, 2021 and 2020, respectively. In addition, EOG's Trinidadian subsidiary maintains a contributory defined benefit pension plan and a matched savings plan, both of which are available to most of the employees of the Trinidadian subsidiary, the costs of which are not material.

Postretirement Health Care. EOG has postretirement medical and dental benefits in place for eligible United States and Trinidad employees and their eligible dependents, the costs of which are not material.

10.    Long-Term Debt and Common Stock

Long-Term Debt. EOG had no outstanding commercial paper borrowings at September 30, 2021 and December 31, 2020, and did not utilize any commercial paper borrowings during the nine months ended September 30, 2021 and 2020.

EOG currently has a $2.0 billion senior unsecured Revolving Credit Agreement (Agreement) with domestic and foreign lenders (Banks). The Agreement has a scheduled maturity date of June 27, 2024, and includes an option for EOG to extend, on up to two occasions, the term for successive one-year periods subject to certain terms and conditions. The Agreement (i) commits the Banks to provide advances up to an aggregate principal amount of $2.0 billion at any one time outstanding, with an option for EOG to request increases in the aggregate commitments to an amount not to exceed $3.0 billion, subject to certain terms and conditions and (ii) includes a swingline subfacility and a letter of credit subfacility. Advances under the Agreement will accrue interest based, at EOG's option, on either LIBOR plus an applicable margin (Eurodollar rate) or the base rate (as defined in the Agreement) plus an applicable margin. The Agreement contains representations, warranties, covenants and events of default that EOG believes are customary for investment-grade, senior unsecured commercial bank credit agreements, including a financial covenant for the maintenance of a ratio of total debt-to-capitalization (as such terms are defined in the Agreement) of no greater than 65%. At September 30, 2021, EOG was in compliance with this financial covenant. At September 30, 2021 and December 31, 2020, there were no borrowings or letters of credit outstanding under the Agreement. The Eurodollar rate and base rate (inclusive of the applicable margin), had there been any amounts borrowed under the Agreement at September 30, 2021, would have been 0.98% and 3.25%, respectively.

On February 1, 2021, EOG repaid upon maturity the $750 million aggregate principal amount of its 4.100% Senior Notes due 2021.

Common Stock. On February 25, 2021, EOG's Board increased the quarterly cash dividend on the common stock from the previous $0.375 per share to $0.4125 per share, effective beginning with the dividend paid on April 30, 2021, to stockholders of record as of April 16, 2021. On May 6, 2021, EOG's Board declared a special cash dividend on the common stock of $1.00 per share in addition to a quarterly dividend of $0.4125 per share. Both the special cash dividend and the quarterly cash dividend were paid on July 30, 2021 to stockholders of record as of July 16, 2021.

On November 4, 2021, EOG's Board (i) increased the quarterly cash dividend on the common stock from the previous $0.4125 per share to $0.75 per share, effective beginning with the dividend to be paid on January 28, 2022, to stockholders of record as of January 14, 2022, (ii) declared a second special cash dividend on the common stock of $2.00 per share, payable on December 30, 2021, to stockholders of record as of December 15, 2021, (iii) established a new share repurchase authorization to allow for the repurchase by EOG of up to $5 billion of the common stock and (iv) revoked and terminated the share repurchase authorization established by the Board in September 2001.

11.    Fair Value Measurements

Recurring Fair Value Measurements. As more fully discussed in Note 13 to the Consolidated Financial Statements included in EOG's 2020 Annual Report, certain of EOG's financial and nonfinancial assets and liabilities are reported at fair value on the Condensed Consolidated Balance Sheets. The following table provides fair value measurement information within the fair value hierarchy for certain of EOG's financial assets and liabilities carried at fair value on a recurring basis at September 30, 2021 and December 31, 2020 (in millions):

	Fair Value Measurements Using:
	Quoted Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total

Crude Oil Roll Differential Swaps	—		1		—		1

See Note 12 for the balance sheet amounts and classification of EOG's financial derivative instruments at September 30, 2021 and December 31, 2020.

The estimated fair value of commodity derivative contracts was based upon forward commodity price curves based on quoted market prices. Commodity derivative contracts were valued by utilizing an independent third-party derivative valuation provider who uses various types of valuation models, as applicable.

Non-Recurring Fair Value Measurements. The initial measurement of asset retirement obligations at fair value is calculated using discounted cash flow techniques and based on internal estimates of future retirement costs associated with property, plant and equipment. Significant Level 3 inputs used in the calculation of asset retirement obligations include plugging costs and reserve lives. A reconciliation of EOG's asset retirement obligations is presented in Note 6.

When circumstances indicate that proved oil and gas properties may be impaired, EOG compares expected undiscounted future cash flows at a depreciation, depletion and amortization group level to the unamortized capitalized cost of the asset. If the expected undiscounted future cash flows, based on EOG's estimate of (and assumptions regarding) significant Level 3 inputs, including future crude oil, NGLs and natural gas prices, operating costs, development expenditures, anticipated production from proved reserves and other relevant data, are lower than the unamortized capitalized cost, the capitalized cost is reduced to fair value. Fair value is generally calculated using the Income Approach described in the Fair Value Measurement Topic of the Accounting Standards Codification. In certain instances, EOG utilizes accepted offers from third-party purchasers as the basis for determining fair value.

EOG utilized average prices per acre from comparable market transactions and estimated discounted cash flows as the basis for determining the fair value of unproved and proved properties, respectively, received in non-cash property exchanges. See Note 4.

Fair Value Disclosures. EOG's financial instruments, other than commodity derivative contracts, consist of cash and cash equivalents, accounts receivable, accounts payable and current and long-term debt. The carrying values of cash and cash equivalents, accounts receivable and accounts payable approximate fair value.

At September 30, 2021 and December 31, 2020, respectively, EOG had outstanding $4,890 million and $5,640 million aggregate principal amount of senior notes, which had estimated fair values at such dates of approximately $5,609 million and $6,505 million, respectively. The estimated fair value of debt was based upon quoted market prices and, where such prices were not available, other observable (Level 2) inputs regarding interest rates available to EOG at the end of each respective period.

12.    Risk Management Activities

Commodity Price Risk. As more fully discussed in Note 12 to the Consolidated Financial Statements included in EOG's 2020 Annual Report, EOG engages in price risk management activities from time to time. These activities are intended to manage EOG's exposure to fluctuations in commodity prices for crude oil, NGLs and natural gas. EOG utilizes financial commodity derivative instruments, primarily price swap, option, swaption, collar and basis swap contracts, as a means to manage this price risk. EOG has not designated any of its financial commodity derivative contracts as accounting hedges and, accordingly, accounts for financial commodity derivative contracts using the mark-to-market accounting method.

Commodity Derivative Contracts. Presented below is a comprehensive summary of EOG's financial commodity derivative contracts as of September 30, 2021. Crude oil and NGL volumes are presented in thousand barrels per day (MBbld) and prices are presented in dollars per barrel ($/Bbl). Natural gas volumes are presented in million British Thermal Units per day (MMBtud) and prices are presented in dollars per million British Thermal Units ($/MMBtu).

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – (Concluded)

(Unaudited)

Credit Risk. Notional contract amounts are used to express the magnitude of a financial derivative. The amounts potentially subject to credit risk, in the event of nonperformance by the counterparties, are equal to the fair value of such contracts (see Note 11). EOG evaluates its exposures to significant counterparties on an ongoing basis, including those arising from physical and financial transactions. In some instances, EOG renegotiates payment terms and/or requires collateral, parent guarantees or letters of credit to minimize credit risk.

All of EOG's derivative instruments are covered by International Swap Dealers Association Master Agreements (ISDAs) with counterparties. The ISDAs may contain provisions that require EOG, if it is the party in a net liability position, to post collateral when the amount of the net liability exceeds the threshold level specified for EOG's then-current credit ratings. In addition, the ISDAs may also provide that as a result of certain circumstances, including certain events that cause EOG's credit ratings to become materially weaker than its then-current ratings, the counterparty may require all outstanding derivatives under the ISDAs to be settled immediately. See Note 11 for the aggregate fair value of all derivative instruments that were in a net liability position at September 30, 2021 and a net asset position at December 31, 2020. EOG had $308 million of collateral posted and no collateral held at September 30, 2021, and had no collateral posted or held at December 31, 2020.

13.  Acquisitions and Divestitures

During the nine months ended September 30, 2021, EOG paid cash for property acquisitions of $95 million in the United States. Additionally, during the nine months ended September 30, 2021, EOG recognized net gains on asset dispositions of $46 million and received proceeds of approximately $154 million primarily due to the sale of its China operations during the second quarter of 2021.

During the nine months ended September 30, 2020, EOG paid cash for property acquisitions of $67 million in the United States. Additionally, during the nine months ended September 30, 2020, EOG recognized net losses on asset dispositions of $41 million, primarily due to the sales of proved properties and non-cash property exchanges of unproved leasehold in Texas and New Mexico and the disposition of the Marcellus Shale assets, and received proceeds of approximately $189 million, primarily due to the disposition of the Marcellus Shale assets and the sale of other assets in New Mexico.

PART I.  FINANCIAL INFORMATION

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

EOG RESOURCES, INC.

Overview

EOG Resources, Inc., together with its subsidiaries (collectively, EOG), is one of the largest independent (non-integrated) crude oil and natural gas companies in the United States with proved reserves in the United States and Trinidad. EOG operates under a consistent business and operational strategy that focuses predominantly on maximizing the rate of return on investment of capital by controlling operating and capital costs and maximizing reserve recoveries. Pursuant to this strategy, each prospective drilling location is evaluated by its estimated rate of return. This strategy is intended to enhance the generation of cash flow and earnings from each unit of production on a cost-effective basis, allowing EOG to deliver long-term growth in shareholder value and maintain a strong balance sheet. EOG implements its strategy primarily by emphasizing the drilling of internally generated prospects in order to find and develop low-cost reserves. Maintaining the lowest possible operating cost structure, coupled with efficient and safe operations and robust environmental stewardship practices and performance, is integral in the implementation of EOG's strategy.

Recent Developments. In 2020, the COVID-19 pandemic and the measures taken to address and limit the spread of the virus adversely affected the economies and financial markets of the world, resulting in an economic downturn beginning in early 2020 that negatively impacted global demand and prices for crude oil and condensate, natural gas liquids (NGLs) and natural gas. In response, OPEC+, a consortium of OPEC (Organization of Petroleum Exporting Countries) and certain non-OPEC global producers (Russia, Kazakhstan and others), agreed to voluntarily curtail crude oil supplies beginning in April 2020 with a schedule to bring back some of these curtailments through April 2021. Certain other non-OPEC+ countries also curtailed production and/or reduced investments in existing and new crude oil projects. This response started the process of balancing supply with demand.

In 2021, the effects of global COVID-19 mitigation efforts, including extensive global fiscal stimulus and the availability of vaccines, tempered by new COVID-19 variant strains and corresponding containment measures in certain parts of the world, have resulted in overall increased demand for crude oil and condensate, NGLs and natural gas. See ITEM 1A, Risk Factors, of our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, filed on February 25, 2021 (Annual Report), for further discussion. During 2021, OPEC+ has continued amending their schedule of gradually returning all curtailed production through 2022 in response to expected increases in demand for crude oil.

The continuing rebalancing of crude oil demand and supply resulting from improving or stabilizing conditions in certain economies and financial markets of the world, combined with the continuing actions taken by OPEC+, have had a positive impact on crude oil prices in the first nine months of 2021. Prices for crude oil and condensate and NGLs returned to pre-pandemic levels in the first quarter of 2021, while natural gas prices recovered at the beginning of 2021.

We will continue to monitor and assess the COVID-19 pandemic and its effect on crude oil demand, the actions of OPEC+ and their effect on crude oil supply, as well as any executive orders or legislative or regulatory actions that could impact the oil and gas industry, to determine the impact on our business and operations, and take appropriate actions where necessary. For related discussion, see ITEM 1, Business – Regulation, ITEM 1A, Risk Factors and ITEM 7, Management's Discussion and Analysis of Financial Condition and Results of Operations - Overview, of our Annual Report.

Commodity Prices. Prices for crude oil and condensate, NGLs and natural gas have historically been volatile. This volatility is expected to continue due to the many uncertainties associated with the world political and economic environment and the global supply of, and demand for, crude oil, NGLs and natural gas and the availability of other energy supplies, the relative competitive relationships of the various energy sources in the view of consumers and other factors.

The market prices of crude oil and condensate, NGLs and natural gas impact the amount of cash generated from EOG's operating activities, which, in turn, impact EOG's financial position and results of operations.

-23-

For the first nine months of 2021, the average U.S. New York Mercantile Exchange (NYMEX) crude oil and natural gas prices were $64.85 per barrel and $3.18 per million British thermal units (MMBtu), respectively, representing increases of 69% for both from the average NYMEX prices for the same period in 2020. Market prices for NGLs are influenced by the components extracted, including ethane, propane and butane and natural gasoline, among others, and the respective market pricing for each component. In February 2021, EOG realized higher-than-average daily prices on certain days for deliveries of natural gas volumes due to disruptions throughout the United States from Winter Storm Uri.

United States. EOG's efforts to identify plays with large reserve potential have proven to be successful. EOG continues to drill numerous wells in large acreage plays, which in the aggregate have contributed substantially to, and are expected to continue to contribute substantially to, EOG's crude oil and condensate, NGLs and natural gas production. EOG has placed an emphasis on applying its horizontal drilling and completion expertise to unconventional crude oil and, to a lesser extent, liquids-rich natural gas plays.

During the first nine months of 2021, EOG continued to focus on increasing drilling, completion and operating efficiencies gained in prior years. Such efficiencies, combined with new innovation, resulted in lower drilling and completion costs. Winter Storm Uri negatively impacted Lease and Well, Transportation and Gathering and Processing Costs in the first quarter of 2021. In addition, EOG continued to evaluate certain potential crude oil and condensate, NGLs and natural gas exploration and development prospects and to look for opportunities to add drilling inventory through leasehold acquisitions, farm-ins, exchanges or tactical acquisitions. On a volumetric basis, as calculated using the ratio of 1.0 barrel of crude oil and condensate or NGLs to 6.0 thousand cubic feet of natural gas, crude oil and condensate and NGLs production accounted for approximately 75% and 76% of EOG's United States production during the first nine months of 2021 and 2020, respectively. During the first nine months of 2021, EOG's drilling and completion activities occurred primarily in the Delaware Basin play, Eagle Ford play and Rocky Mountain area. EOG's major producing areas in the United States are in New Mexico and Texas. EOG faced interruptions to sales in certain markets due to disruptions throughout the United States from Winter Storm Uri in the first quarter of 2021.

Trinidad. In Trinidad, EOG continues to deliver natural gas under existing supply contracts. Several fields in the South East Coast Consortium Block, Modified U(a) Block, Block 4(a), Modified U(b) Block, the Banyan Field and the Sercan Area have been developed and are producing natural gas which is sold to the National Gas Company of Trinidad and Tobago Limited and its subsidiary, and crude oil and condensate which is sold to Heritage Petroleum Company Limited (Heritage).

In March 2021, EOG signed a farmout agreement with Heritage, which allows EOG to earn a 65% working interest in a portion of the contract area (EOG Area) governed by the Trinidad Northern Area License. The EOG Area is located offshore the southwest coast of Trinidad. EOG is currently planning and preparing to drill one net exploratory well in the first half of 2022. EOG continues to make progress on the design and fabrication of a platform and related facilities for its previously announced discovery in the Modified U(a) Block.

Other International. In the Sultanate of Oman, a Royal Decree was issued on March 9, 2021, and EOG became a participant in the Exploration and Production Sharing Agreement for Block 49, holding a 50% working interest. EOG's partner in Block 49 completed the drilling and testing of one gross exploratory well in the first quarter of 2021. The results are currently being evaluated. In Block 36, where EOG holds a 100% working interest, drilling commenced on one exploratory well in the third quarter of 2021. EOG plans to drill one additional exploratory well in Block 36 by the end of 2021.

In Australia, a subsidiary of EOG entered into a purchase and sale agreement in April 2021 to acquire a 100% interest in the WA-488-P Block, located offshore Western Australia. The purchase and sale agreement is subject to customary closing conditions and is expected to close in the fourth quarter of 2021.

In the Sichuan Basin, Sichuan Province, China, EOG worked with its partner, PetroChina, under a production sharing contract and other related agreements, to ensure uninterrupted production. All natural gas produced from the Baijaochang Field was sold under a long-term contract to PetroChina.

In May 2021, EOG closed the sale of its subsidiary which held all of its assets in China. Net production was approximately 25 million cubic feet per day (MMcfd) of natural gas. EOG no longer has any operations or assets in China.

-24-

EOG continues to evaluate other select crude oil and natural gas opportunities outside the United States, primarily by pursuing exploitation opportunities in countries where indigenous crude oil and natural gas reserves have been identified.

2021 Capital and Operating Plan. Total 2021 capital expenditures are estimated to range from approximately $3.8 billion to $4.0 billion, including facilities and gathering, processing and other expenditures, and excluding acquisitions and non-cash transactions. EOG plans to continue to focus a substantial portion of its exploration and development expenditures in its major producing areas in the United States. In particular, EOG will continue to be focused on United States crude oil drilling activity in its Delaware Basin play, Eagle Ford play and Rocky Mountain area where it generates its highest rates-of-return. To further enhance the economics of these plays, EOG expects to continue to improve well performance and lower drilling and completion costs through efficiency gains, new innovation and initiatives to manage procurement and service costs. In addition, EOG has spent, and expects to continue to spend, a portion of its 2021 capital expenditures on leasing acreage and evaluating new prospects.

Full-year 2021 total crude oil production is expected to remain at fourth quarter 2020 levels. Further, EOG expects to continue to focus on reducing operating costs in 2021 through efficiency improvements.

Management continues to believe EOG has one of the strongest prospect inventories in EOG's history. When it fits EOG's strategy, EOG will make acquisitions that bolster existing drilling programs or offer incremental exploration and/or production opportunities.

Capital Structure. One of management's key strategies is to maintain a strong balance sheet with a consistently below average debt-to-total capitalization ratio as compared to those in EOG's peer group. EOG's debt-to-total capitalization ratio was 19% at September 30, 2021 and 22% at December 31, 2020. As used in this calculation, total capitalization represents the sum of total current and long-term debt and total stockholders' equity.

On February 1, 2021, EOG repaid upon maturity the $750 million aggregate principal amount of its 4.100% Senior Notes due 2021.

At September 30, 2021, EOG maintained a strong financial and liquidity position, including $4.3 billion of cash and cash equivalents on hand and $2.0 billion of availability under its senior unsecured revolving credit facility.

EOG has significant flexibility with respect to financing alternatives, including borrowings under its commercial paper program, bank borrowings, borrowings under its senior unsecured revolving credit facility, joint development agreements and similar agreements and equity and debt offerings.

Dividend Declarations and Share Repurchase Authorization. On November 4, 2021, EOG's Board (i) increased the quarterly cash dividend on the common stock from the previous $0.4125 per share to $0.75 per share, effective beginning with the dividend to be paid on January 28, 2022, to stockholders of record as of January 14, 2022, (ii) declared a special cash dividend on the common stock of $2.00 per share, payable on December 30, 2021, to stockholders of record as of December 15, 2021, (iii) established a new share repurchase authorization to allow for the repurchase by EOG of up to $5 billion of the common stock and (iv) revoked and terminated the share repurchase authorization established by the Board in September 2001. See Part II, Item 2, Unregistered Sales of Equity Securities and Use of Proceeds, of this Quarterly Report on Form 10-Q for additional discussion.

(4)Thousand barrels of oil equivalent per day or million barrels of oil equivalent, as applicable; includes crude oil and condensate, NGLs and natural gas. Crude oil equivalent volumes are determined using a ratio of 1.0 barrel of crude oil and condensate or NGLs to 6.0 thousand cubic feet of natural gas. MMBoe is calculated by multiplying the MBoed amount by the number of days in the period and then dividing that amount by one thousand.

-27-

Wellhead crude oil and condensate revenues for the third quarter of 2021 increased $1,534 million, or 110%, to $2,929 million from $1,395 million for the same period of 2020. The increase was due to a higher composite average price ($1,266 million) and an increase of 71.9 MBbld, or 19%, in wellhead crude oil and condensate production ($268 million). Increased production was primarily in the Permian Basin and the Eagle Ford. EOG's composite wellhead crude oil and condensate price for the third quarter of 2021 increased 76% to $70.85 per barrel compared to $40.15 per barrel for the same period of 2020.

NGL revenues for the third quarter of 2021 increased $363 million, or 196%, to $548 million from $185 million for the same period of 2020 due to a higher composite average price ($340 million) and an increase of 17.8 MBbld, or 13%, in NGL deliveries ($23 million). Increased production was primarily in the Permian Basin. EOG's composite NGL price for the third quarter of 2021 increased 163% to $37.72 per barrel compared to $14.34 per barrel for the same period of 2020.

Wellhead natural gas revenues for the third quarter of 2021 increased $384 million, or 209%, to $568 million from $184 million for the same period of 2020. The increase was due to a higher average composite price ($347 million) and an increase in natural gas deliveries ($37 million). Natural gas deliveries for the third quarter of 2021 increased 232 MMcfd, or 19%, compared to the same period of 2020 due primarily to increased production of associated natural gas from the Permian Basin and higher natural gas volumes in Trinidad, partially offset by lower natural gas volumes associated with the disposition of the Marcellus Shale assets in the third quarter of 2020, lower deliveries in South Texas and lower natural gas volumes associated with the disposition of the China assets in the second quarter of 2021. EOG's composite wellhead natural gas price for the third quarter of 2021 increased 158% to $4.34 per Mcf compared to $1.68 per Mcf for the same period of 2020.

During the third quarter of 2021, EOG recognized net losses on the mark-to-market of financial commodity derivative contracts of $494 million compared to net losses of $4 million for the same period of 2020. During the third quarter of 2021, net cash paid for settlements of financial commodity derivative contracts was $293 million compared to net cash received from settlements of financial commodity derivative contracts of $275 million for the same period of 2020.

Gathering, processing and marketing revenues are revenues generated from sales of third-party crude oil, NGLs and natural gas, as well as fees associated with gathering third-party natural gas and revenues from sales of EOG-owned sand. Purchases and sales of third-party crude oil and natural gas may be utilized in order to balance firm capacity at third-party facilities with production in certain areas and to utilize excess capacity at EOG-owned facilities. EOG sells sand in order to balance the timing of firm purchase agreements with completion operations. Marketing costs represent the costs to purchase third-party crude oil, natural gas and sand and the associated transportation costs, as well as costs associated with EOG-owned sand sold to third parties.

Gathering, processing and marketing revenues less marketing costs for the third quarter of 2021 decreased $14 million as compared to the same period of 2020 primarily due to lower margins on crude oil marketing activities, partially offset by higher margins on natural gas marketing activities.

-28-

Operating and Other Expenses.  For the third quarter of 2021, operating expenses of $3,294 million were $1,045 million higher than the $2,249 million incurred during the third quarter of 2020.  The following table presents the costs per barrel of oil equivalent (Boe) for the three-month periods ended September 30, 2021 and 2020:

	Three Months Ended September 30,
	2021		2020
Lease and Well	$	3.48	$	3.45
Transportation Costs	2.82		2.74
Gathering and Processing Costs	1.87		1.74
Depreciation, Depletion and Amortization (DD&A) -
Oil and Gas Properties	11.47		12.00
Other Property, Plant and Equipment	0.46		0.49
General and Administrative (G&A)	1.83		1.89
Interest Expense, Net	0.62		0.81
Total (1)	$	22.55	$	23.12

(1)Total excludes exploration costs, dry hole costs, impairments, marketing costs and taxes other than income.

The primary factors impacting the cost components of per-unit rates of lease and well, transportation costs, gathering and processing costs, DD&A, G&A and net interest expense for the three months ended September 30, 2021, compared to the same period of 2020, are set forth below. See "Operating Revenues and Other" above for a discussion of wellhead volumes.

Lease and well expenses include expenses for EOG-operated properties, as well as expenses billed to EOG from other operators where EOG is not the operator of a property. Lease and well expenses can be divided into the following categories: costs to operate and maintain crude oil and natural gas wells, the cost of workovers and lease and well administrative expenses. Operating and maintenance costs include, among other things, pumping services, salt water disposal, equipment repair and maintenance, compression expense, lease upkeep and fuel and power. Workovers are operations to restore or maintain production from existing wells.

Each of these categories of costs individually fluctuates from time to time as EOG attempts to maintain and increase production while maintaining efficient, safe and environmentally responsible operations. EOG continues to increase its operating activities by drilling new wells in existing and new areas. Operating and maintenance costs within these existing and new areas, as well as the costs of services charged to EOG by vendors, fluctuate over time.

Lease and well expenses of $270 million for the third quarter of 2021 increased $43 million from $227 million for the same prior year period primarily due to increased operating and maintenance costs in the United States ($19 million), increased workovers expenditures in the United States ($15 million) and increased lease and well administrative expenses in the United States ($7 million). Lease and well expenses increased in the United States primarily due to increased operating activities resulting in increased production.

Transportation costs represent costs associated with the delivery of hydrocarbon products from the lease or an aggregation point on EOG's gathering system to a downstream point of sale. Transportation costs include transportation fees, storage and terminal fees, the cost of compression (the cost of compressing natural gas to meet pipeline pressure requirements), the cost of dehydration (the cost associated with removing water from natural gas to meet pipeline requirements), gathering fees and fuel costs.

Transportation costs of $219 million for the third quarter of 2021 increased $39 million from $180 million for the same prior year period primarily due to increased transportation costs related to production from the Permian Basin ($29 million) and the Rocky Mountain area ($10 million).

Gathering and processing costs represent operating and maintenance expenses and administrative expenses associated with operating EOG's gathering and processing assets as well as natural gas processing fees and certain NGL fractionation fees paid to third parties. EOG pays third parties to process the majority of its natural gas production to extract NGLs.

-29-

Gathering and processing costs increased $30 million to $145 million for the third quarter of 2021 compared to $115 million for the same prior year period primarily due to increased gathering and processing fees ($14 million) and operating and maintenance expense ($8 million), both related to production from the Permian Basin.

DD&A of the cost of proved oil and gas properties is calculated using the unit-of-production method. EOG's DD&A rate and expense are the composite of numerous individual DD&A group calculations. There are several factors that can impact EOG's composite DD&A rate and expense, such as field production profiles, drilling or acquisition of new wells, disposition of existing wells and reserve revisions (upward or downward) primarily related to well performance, economic factors and impairments. Changes to these factors may cause EOG's composite DD&A rate and expense to fluctuate from period to period. DD&A of the cost of other property, plant and equipment is generally calculated using the straight-line depreciation method over the useful lives of the assets.

DD&A expenses for the third quarter of 2021 increased $104 million to $927 million from $823 million for the same prior year period. DD&A expenses associated with oil and gas properties for the third quarter of 2021 were $100 million higher than the same prior year period. The increase primarily reflects increased production in the United States ($137 million) and in Trinidad ($5 million), partially offset by lower unit rates in the United States ($39 million). Unit rates in the United States decreased primarily due to reserves added at lower costs as a result of increased efficiencies.

G&A expenses of $142 million for the third quarter of 2021 increased $17 million from $125 million for the same prior year period primarily due to increased employee-related costs ($20 million) and joint interest billings deemed uncollectible ($5 million), partially offset by decreased idle equipment and termination fees ($13 million).

Interest expense, net of $48 million for the third quarter of 2021 decreased $5 million compared to the same prior year period primarily due to the repayment in February 2021 of the $750 million aggregate principal amount of 4.100% Senior Notes due 2021 ($8 million), partially offset by interest payments for late royalty payments on Oklahoma properties ($3 million).

Exploration costs of $44 million for the third quarter of 2021 increased $6 million from $38 million for the same prior year period due primarily to increased geological and geophysical expenditures in the United States.

Impairments include: amortization of unproved oil and gas property costs as well as impairments of proved oil and gas properties; other property, plant and equipment; and other assets. Unproved properties with acquisition costs that are not individually significant are aggregated, and the portion of such costs estimated to be nonproductive is amortized over the remaining lease term. Unproved properties with individually significant acquisition costs are reviewed individually for impairment. When circumstances indicate that a proved property may be impaired, EOG compares expected undiscounted future cash flows at a DD&A group level to the unamortized capitalized cost of the asset. If the expected undiscounted future cash flows, based on EOG's estimates of (and assumptions regarding) future crude oil, NGLs and natural gas prices, operating costs, development expenditures, anticipated production from proved reserves and other relevant data, are lower than the unamortized capitalized cost, the capitalized cost is reduced to fair value. Fair value is generally calculated by using the Income Approach described in the Fair Value Measurement Topic of the Financial Accounting Standards Board's Accounting Standards Codification. In certain instances, EOG utilizes accepted offers from third-party purchasers as the basis for determining fair value.

-30-

The following table represents impairments for the third quarter of 2021 and 2020 (in millions):

	Three Months Ended September 30,
	2021		2020
Proved properties	$	13	$	26
Unproved properties	69		52
Other assets	—		1
Firm commitment contracts	—		—
Total	$	82	$	79

Taxes other than income include severance/production taxes, ad valorem/property taxes, payroll taxes, franchise taxes and other miscellaneous taxes. Severance/production taxes are generally determined based on wellhead revenues, and ad valorem/property taxes are generally determined based on the valuation of the underlying assets.

Taxes other than income for the third quarter of 2021 increased $151 million to $277 million (6.8% of wellhead revenues) from $126 million (7.2% of wellhead revenues) for the same prior year period. The increase in taxes other than income was primarily due to increased severance/production taxes ($142 million) and increased ad valorem/property taxes ($5 million), all in the United States.

EOG recognized an income tax provision of $334 million for the third quarter of 2021 compared to an income tax benefit of $11 million for the third quarter of 2020, primarily due to increased pretax income.  The net effective tax rate for the third quarter of 2021 increased to 23% from 19% for the third quarter of 2020, mostly due to stock-based compensation tax deficiencies increasing the effective tax rate on pretax income in the third quarter of 2021 and decreasing the effective tax rate on pretax loss in the third quarter of 2020.

Nine Months Ended September 30, 2021 vs. Nine Months Ended September 30, 2020

Wellhead crude oil and condensate revenues for the first nine months of 2021 increased $3,804 million, or 93%, to $7,879 million from $4,075 million for the same period of 2020 due to a higher composite average price ($3,348 million) and an increase of 45.8 MBbld, or 12%, in wellhead crude oil and condensate production ($456 million). Increased production was primarily in the Permian Basin, partially offset by decreased production in the Eagle Ford. EOG's composite wellhead crude oil and condensate price for the first nine months of 2021 increased 74% to $65.14 per barrel compared to $37.44 per barrel for the same period of 2020.

NGL revenues for the first nine months of 2021 increased $790 million, or 180%, to $1,229 million from $439 million for the same period of 2020 due to a higher composite average price ($772 million) and an increase of 6.2 MBbld, or 5%, in NGL deliveries ($18 million). Increased production was primarily in the Permian Basin and the Rocky Mountain area, partially offset by decreased production in the Fort Worth Basin Barnett Shale and the Eagle Ford. EOG's composite NGL price for the first nine months of 2021 increased 168% to $32.07 per barrel compared to $11.95 per barrel for the same period of 2020.

Wellhead natural gas revenues for the first nine months of 2021 increased $1,062 million, or 199%, to $1,597 million from $535 million for the same period of 2020. The increase was due to a higher composite wellhead natural gas price ($992 million) and an increase in natural gas deliveries ($70 million). Natural gas deliveries for the first nine months of 2021 increased 165 MMcfd, or 13%, compared to the same period of 2020 due primarily to increased production of associated natural gas from the Permian Basin and higher natural gas volumes in Trinidad, partially offset by lower natural gas volumes associated with the disposition of the Marcellus Shale assets in the third quarter of 2020 and lower deliveries in South Texas. EOG's composite wellhead natural gas price for the first nine months of 2021 increased 164% to $4.17 per Mcf compared to $1.58 per Mcf for the same period of 2020.

During the first nine months of 2021, EOG recognized net losses on the mark-to-market of financial commodity derivative contracts of $1,288 million compared to net gains of $1,075 million for the same period of 2020. During the first nine months of 2021, net cash paid for settlements of financial commodity derivative contracts was $516 million compared to net cash received from settlements of financial commodity derivative contracts of $999 million for the same period of 2020.

Gathering, processing and marketing revenues less marketing costs for the first nine months of 2021 increased $180 million as compared to the same period of 2020 primarily due to higher margins on crude oil marketing activities, partially offset by lower margins on natural gas marketing activities. The margin on crude oil marketing activities for the first nine months of 2020 was negatively impacted by the price decline for crude oil in inventory awaiting delivery to customers and EOG's decision early in the second quarter of 2020 to reduce commodity price volatility by selling May and June 2020 deliveries under fixed price arrangements.

Operating and Other Expenses. For the first nine months of 2021, operating expenses of $9,024 million were $75 million lower than the $9,099 million incurred during the same period of 2020. The following table presents the costs per Boe for the nine-month periods ended September 30, 2021 and 2020:

	Nine Months Ended September 30,
	2021		2020
Lease and Well	$	3.63	$	3.97
Transportation Costs	2.85		2.67

The primary factors impacting the cost components of per-unit rates of lease and well, transportation costs, gathering and processing costs, DD&A, and net interest expense for the nine months ended September 30, 2021, compared to the same period of 2020 are set forth below. See "Operating Revenues" above for a discussion of wellhead volumes.

Lease and well expenses of $810 million for the first nine months of 2021 increased $8 million from $802 million for the same prior year period primarily due to increased workovers expenditures in the United States ($12 million) and increased operating and maintenance costs in Trinidad ($4 million), partially offset by decreased operating and maintenance costs in Canada ($6 million) and the United States ($3 million).

Transportation costs of $635 million for the first nine months of 2021 increased $95 million from $540 million for the same prior year period primarily due to increased transportation costs related to production from the Permian Basin ($91 million) and the Rocky Mountain area ($17 million), partially offset by decreased transportation costs related to production from the Eagle Ford ($7 million).

Gathering and processing costs of $412 million for the first nine months of 2021 increased $72 million compared to the same prior year period primarily due to increased gathering and processing fees related to production from the Permian Basin ($31 million) and the Rocky Mountain area ($12 million), increased operating and maintenance expenses related to production from the Permian Basin ($13 million) and the Rocky Mountain area ($7 million) and increased gathering and processing general and administrative costs in the United States ($11 million).

DD&A expenses for the first nine months of 2021 increased $211 million to $2,741 million from $2,530 million for the same prior year period. DD&A expenses associated with oil and gas properties for the first nine months of 2021 were $199 million higher than the same prior year period. The increase primarily reflects increased production in the United States ($239 million) and in Trinidad ($11 million) and higher unit rates in Trinidad ($12 million), partially offset by lower unit rates in the United States ($55 million). Unit rates in the United States decreased primarily due to reserves added at lower costs as a result of increased efficiencies. DD&A expenses associated with other property, plant and equipment for the first nine months of 2021 were $11 million higher than the same prior year period primarily due to an increase in expense related to storage assets.

Interest expense, net of $140 million for the first nine months of 2021 decreased $12 million compared to the same prior year period primarily due to the repayment in February 2021 of the $750 million aggregate principal amount of 4.100% Senior Notes due 2021 ($21 million), repayment in June 2020 of the $500 million aggregate principal amount of 4.40% Senior Notes due 2020 ($9 million) and repayment in April 2020 of the $500 million aggregate principal amount of 2.45% Senior Notes due 2020 ($3 million), partially offset by the issuance in April 2020 of the $750 million aggregate principal amount of 4.950% Senior Notes due 2050 ($11 million) and issuance in April 2020 of the $750 million aggregate principal amount of 4.375% Senior Notes due 2030 ($10 million).

Exploration costs of $112 million for the first nine months of 2021 increased $7 million from $105 million for the same prior year period due primarily to increased geological and geophysical expenditures ($9 million), partially offset by decreased general and administrative expenditures ($5 million), all in the United States.

The following table represents impairments for the nine-month periods ended September 30, 2021 and 2020 (in millions):

	Nine Months Ended September 30,
	2021		2020
Proved properties	$	13	$	1,185
Unproved properties	155		421
Other assets	—		291
Firm commitment contracts	2		60
Total	$	170	$	1,957

-34-

Impairments of proved properties in the first nine months of 2020 were primarily due to the decline in commodity prices and were primarily related to the write-down to fair value of legacy and non-core natural gas, crude oil and combo plays in the United States. Impairments of unproved oil and gas properties included charges of $252 million in the first nine months of 2020 for certain leasehold costs that are no longer expected to be developed before expiration. Impairments of other assets in the first nine months of 2020 were primarily for the write-down to fair value of sand and crude-by-rail assets and a commodity price-related write-down of other assets. Impairments of firm commitment contracts in the first nine months of 2020 were a result of the decision to exit the Horn River Basin in Canada.

Taxes other than income for the first nine months of 2021 increased $367 million to $731 million (6.8% of wellhead revenues) from $364 million (7.2% of wellhead revenues) for the same prior year period. The increase in taxes other than income was primarily due to increased severance/production taxes ($347 million) and decreased state severance tax refunds ($13 million), all in the United States, and increased severance/production taxes in Trinidad ($5 million).

Other income, net for the first nine months of 2021 decreased $17 million compared to the same prior year period primarily due to an increase in deferred compensation expense ($18 million) and decreased interest income ($8 million), partially offset by higher equity income from ammonia plants in Trinidad ($11 million).

EOG recognized an income tax provision of $755 million for the first nine months of 2021 compared to an income tax benefit of $225 million for the first nine months of 2020, primarily due to increased pretax income. The net effective tax rate for the first nine months of 2021 increased to 22% from 19% in the first nine months of 2020. The higher effective tax rate is mostly due to taxes attributable to EOG's foreign operations.

Capital Resources and Liquidity

Cash Flow. The primary sources of cash for EOG during the nine months ended September 30, 2021, were funds generated from operations and proceeds from sales of assets. The primary uses of cash were funds used in operations; exploration and development expenditures; dividend payments to stockholders; long-term debt repayments; net cash paid for settlements of commodity derivative contracts and other property, plant and equipment expenditures. During the first nine months of 2021, EOG's cash balance increased $964 million to $4,293 million from $3,329 million at December 31, 2020.

Net cash provided by operating activities of $5,625 million for the first nine months of 2021 increased $1,738 million compared to the same period of 2020 primarily due to an increase in wellhead revenues ($5,656 million) and an increase in gathering, processing and marketing revenues less marketing costs ($180 million), partially offset by an increase in net cash paid for settlements of financial commodity derivative contracts ($1,515 million), net cash used in working capital in the first nine months of 2021 ($897 million) compared to net cash provided by working capital in the first nine months of 2020 ($467 million), an unfavorable change in net cash paid for income taxes ($1,038 million) and an increase in cash operating expenses ($529 million).

Net cash used in investing activities of $2,582 million for the first nine months of 2021 decreased $129 million compared to the same period of 2020 due to net cash provided by working capital associated with investing activities in the first nine months of 2021 ($100 million) compared to net cash used in working capital associated with investing activities in the first nine months of 2020 ($276 million) and a decrease in additions to other property, plant and equipment ($18 million), partially offset by an increase in additions to oil and gas properties ($230 million) and a decrease in proceeds from the sale of assets ($35 million).

Net cash used in financing activities of $2,079 million for the first nine months of 2021 included cash dividend payments ($1,278 million), repayments of long-term debt ($750 million), purchases of treasury stock in connection with stock compensation plans ($33 million) and repayment of finance lease liabilities ($27 million). Net cash used in financing activities of $140 million for the first nine months of 2020 included repayments of long-term debt ($1,000 million) and cash dividend payments ($601 million), partially offset by net proceeds from the issuance of long-term debt ($1,484 million).

Total Expenditures. For the year 2021, EOG's updated budget for exploration and development and other property, plant and equipment expenditures is estimated to range from approximately $3.8 billion to $4.0 billion, excluding acquisitions and non-cash transactions. The table below sets out components of total expenditures for the nine-month periods ended September 30, 2021 and 2020 (in millions):

	Nine Months Ended September 30,
	2021		2020
Expenditure Category
Capital
Exploration and Development Drilling	$	2,097	$	2,072
Facilities	287		248
Leasehold Acquisitions (1)	194		163
Property Acquisitions (2)	99		74
Capitalized Interest	24		24
Subtotal	2,701		2,581
Exploration Costs	112		105
Dry Hole Costs	28		13
Exploration and Development Expenditures	2,841		2,699
Asset Retirement Costs	56		69
Total Exploration and Development Expenditures	2,897		2,768
Other Property, Plant and Equipment (3)	221		238
Total Expenditures	$	3,118	$	3,006

(1)    Leasehold acquisitions included $37 million and $128 million for the nine-month periods ended September 30, 2021 and 2020, respectively, related to non-cash property exchanges.

(2)    Property acquisitions included $4 million and $7 million for the nine-month periods ended September 30, 2021 and 2020, respectively, related to non-cash property exchanges.

(3)    Other property, plant and equipment included $74 million and $73 million of non-cash additions for the nine-month periods ended September 30, 2021 and 2020, respectively, primarily related to finance lease transactions for storage facilities.

Exploration and development expenditures of $2,841 million for the first nine months of 2021 were $142 million higher than the same period of 2020 primarily due to increased exploration and development drilling expenditures in the United States ($47 million) and Other International ($21 million), increased facilities expenditures ($39 million), increased leasehold acquisitions ($31 million) and increased property acquisitions ($25 million), partially offset by decreased exploration and development expenditures in Trinidad ($44 million). Exploration and development expenditures for the first nine months of 2021 of $2,841 million consisted of $2,299 million in development drilling and facilities, $419 million in exploration, $99 million in property acquisitions and $24 million in capitalized interest. Exploration and development expenditures for the first nine months of 2020 of $2,699 million consisted of $2,236 million in development drilling and facilities, $365 million in exploration, $74 million in property acquisitions and $24 million in capitalized interest.

The level of exploration and development expenditures, including acquisitions, will vary in future periods depending on energy market conditions and other economic factors. EOG believes it has significant flexibility and availability with respect to financing alternatives and the ability to adjust its exploration and development expenditure budget as circumstances warrant. While EOG has certain continuing commitments associated with expenditure plans related to its operations, such commitments are not expected to be material when considered in relation to the total financial capacity of EOG.

Commodity Derivative Transactions. As more fully discussed in Note 12 to the Consolidated Financial Statements included in EOG's Annual Report on Form 10-K for the year ended December 31, 2020, filed on February 25, 2021, EOG engages in price risk management activities from time to time. These activities are intended to manage EOG's exposure to fluctuations in commodity prices for crude oil, NGLs and natural gas. EOG utilizes financial commodity derivative instruments, primarily price swap, option, swaption, collar and basis swap contracts, as a means to manage this price risk. EOG has not designated any of its financial commodity derivative contracts as accounting hedges and, accordingly, accounts for financial commodity derivative contracts using the mark-to-market accounting method. Under this accounting method, changes in the fair value of outstanding financial instruments are recognized as gains or losses in the period of change and are recorded as Gains (Losses) on Mark-to-Market Commodity Derivative Contracts on the Condensed Consolidated Statements of Income (Loss) and Comprehensive Income (Loss). The related cash flow impact is reflected in Cash Flows from Operating Activities on the Condensed Consolidated Statements of Cash Flows.

The total fair value of EOG's commodity derivative contracts was reflected on the Condensed Consolidated Balance Sheets at September 30, 2021, as a net liability of $301 million.

Commodity Derivative Contracts. Presented below is a comprehensive summary of EOG's financial commodity derivative contracts as of October 29, 2021. Crude oil and NGL volumes are presented in MBbld and prices are presented in $/Bbl. Natural gas volumes are presented in MMBtu per day (MMBtud) and prices are presented in dollars per MMBtu ($/MMBtu).

This Quarterly Report on Form 10-Q includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of historical facts, including, among others, statements and projections regarding EOG's future financial position, operations, performance, business strategy, goals, returns and rates of return, budgets, reserves, levels of production, capital expenditures, costs and asset sales, statements regarding future commodity prices and statements regarding the plans and objectives of EOG's management for future operations, are forward‐looking statements. EOG typically uses words such as "expect," "anticipate," "estimate," "project," "strategy," "intend," "plan," "target," "aims," "goal," "may," "will," "focused on," "should" and "believe" or the negative of those terms or other variations or comparable terminology to identify its forward‐looking statements. In particular, statements, express or implied, concerning EOG's future operating results and returns or EOG's ability to replace or increase reserves, increase production, generate returns and rates of return, replace or increase drilling locations, reduce or otherwise control operating costs and capital expenditures, generate cash flows, pay down or refinance indebtedness, or pay and/or increase dividends are forward‐looking statements. Forward-looking statements are not guarantees of performance. Although EOG believes the expectations reflected in its forward-looking statements are reasonable and are based on reasonable assumptions, no assurance can be given that these assumptions are accurate or that any of these expectations will be achieved (in full or at all) or will prove to have been correct. Moreover, EOG's forward-looking statements may be affected by known, unknown or currently unforeseen risks, events or circumstances that may be outside EOG's control. Important factors that could cause EOG's actual results to differ materially from the expectations reflected in EOG's forward-looking statements include, among others:

•the timing, extent and duration of changes in prices for, supplies of, and demand for, crude oil and condensate, natural gas liquids, natural gas and related commodities;

•the extent to which EOG is successful in its efforts to acquire or discover additional reserves;

•the extent to which EOG is successful in its efforts to (i) economically develop its acreage in, (ii) produce reserves and achieve anticipated production levels and rates of return from, (iii) decrease or otherwise control its drilling, completion, operating and capital costs related to, and (iv) maximize reserve recovery from, its existing and future crude oil and natural gas exploration and development projects and associated potential and existing drilling locations;

•the extent to which EOG is successful in its efforts to market its production of crude oil and condensate, natural gas liquids, and natural gas;

•security threats, including cybersecurity threats and disruptions to our business and operations from breaches of our information technology systems, physical breaches of our facilities and other infrastructure or breaches of the information technology systems, facilities and infrastructure of third parties with which we transact business;

•the availability, proximity and capacity of, and costs associated with, appropriate gathering, processing, compression, storage, transportation, refining, and export facilities;

•the availability, cost, terms and timing of issuance or execution of, and competition for, mineral licenses and leases and governmental and other permits and rights-of-way, and EOG's ability to retain mineral licenses and leases;

•the impact of, and changes in, government policies, laws and regulations, including any changes or other actions which may result from the recent U.S. elections and change in U.S. administration and including tax laws and regulations; climate change and other environmental, health and safety laws and regulations relating to air emissions, disposal of produced water, drilling fluids and other wastes, hydraulic fracturing and access to and use of water; laws and regulations affecting the leasing of acreage and permitting for oil and gas drilling and the calculation of royalty payments in respect of oil and gas production; laws and regulations imposing additional permitting and disclosure requirements, additional operating restrictions and conditions or restrictions on drilling and completion operations and on the transportation of crude oil and natural gas; laws and regulations with respect to derivatives and hedging activities; and laws and regulations with respect to the import and export of crude oil, natural gas and related commodities;

•EOG's ability to effectively integrate acquired crude oil and natural gas properties into its operations, fully identify existing and potential problems with respect to such properties and accurately estimate reserves, production and drilling, completing and operating costs with respect to such properties;

•the extent to which EOG's third-party-operated crude oil and natural gas properties are operated successfully and economically;

•competition in the oil and gas exploration and production industry for the acquisition of licenses, leases and properties, employees and other personnel, facilities, equipment, materials and services;

-40-

•the availability and cost of employees and other personnel, facilities, equipment, materials (such as water and tubulars) and services;

EOG's forward-looking statements speak only as of the date made, and EOG undertakes no obligation, other than as required by applicable law, to update or revise its forward-looking statements, whether as a result of new information, subsequent events, anticipated or unanticipated circumstances or otherwise.

ITEM 4. CONTROLS AND PROCEDURES

EOG RESOURCES, INC.

Disclosure Controls and Procedures. EOG's management, with the participation of EOG's principal executive officer and principal financial officer, evaluated the effectiveness of EOG's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (Exchange Act)) as of the end of the period covered by this Quarterly Report on Form 10-Q (Evaluation Date). Based on this evaluation, EOG's principal executive officer and principal financial officer have concluded that EOG's disclosure controls and procedures were effective as of the Evaluation Date in ensuring that information that is required to be disclosed in the reports EOG files or furnishes under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the United States Securities and Exchange Commission's rules and forms and (ii) accumulated and communicated to EOG's management, as appropriate, to allow timely decisions regarding required disclosure.

Internal Control Over Financial Reporting. There were no changes in EOG's internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act) that occurred during the quarterly period covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, EOG's internal control over financial reporting.

PART II. OTHER INFORMATION

EOG RESOURCES, INC.

ITEM 1.    LEGAL PROCEEDINGS

See Part I, Item 1, Note 8 to Condensed Consolidated Financial Statements, which is incorporated herein by reference.

Item 103 of Regulation S-K promulgated under the Securities Exchange Act of 1934, as amended, requires disclosure regarding certain proceedings arising under federal, state or local environmental laws when a governmental authority is a party to the proceedings and such proceedings involve potential monetary sanctions that EOG reasonably believes will exceed a specified threshold. Pursuant to recent amendments to this item, EOG will be using a threshold of $1 million for purposes of determining whether disclosure of any such proceedings is required. EOG believes proceedings under this threshold are not material to EOG's business and financial condition. Applying this threshold, there are no environmental proceedings to disclose for the quarter ended September 30, 2021.

ITEM 2.    UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

The following table sets forth, for the periods indicated, EOG's share repurchase activity:

Period	Total Number of Shares Purchased (1)	Average Price Paid Per Share		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs	Maximum Number of Shares that May Yet Be Purchased Under The Plans or Programs (2) (3)
July 1, 2021 - July 31, 2021	6,410	$	79.96	—	6,386,200
August 1, 2021 - August 31, 2021	3,547	72.82		—	6,386,200
September 1, 2021 - September 30, 2021	247,167	82.06		—	6,386,200
Total	257,124	81.88		—

(1)The 257,124 total shares for the quarter ended September 30, 2021, consist solely of shares that were withheld by or returned to EOG (i) in satisfaction of tax withholding obligations that arose upon the exercise of employee stock options or stock-settled stock appreciation rights or the vesting of restricted stock, restricted stock unit, or performance unit grants or (ii) in payment of the exercise price of employee stock options. These shares do not count against the 10 million aggregate share repurchase authorization by EOG's Board of Directors (Board) discussed below.

(2)In September 2001, the Board authorized the repurchase of up to 10 million shares of EOG's common stock. During the third quarter of 2021, EOG did not repurchase any shares under the Board-authorized repurchase program. EOG last repurchased shares under this program in March 2003.

(3)On November 4, 2021, the Board (i) established a new share repurchase authorization to allow for the repurchase by EOG of up to $5 billion of its common stock and (ii) revoked and terminated the share repurchase authorization established by the Board in September 2001. Under the new authorization, EOG may repurchase shares from time to time, at management's discretion, in accordance with applicable securities laws, including through open market transactions, privately negotiated transactions or any combination thereof. The timing and amount of repurchases, if any, will be at the discretion of EOG's management and will depend on a variety of factors, including the then-trading price of EOG's common stock, corporate and regulatory requirements, and other market and economic conditions. Repurchased shares will be held as treasury shares and will be available for general corporate purposes. The new share repurchase authorization has no time limit, does not require EOG to repurchase a specific number of shares and may be modified, suspended, or terminated by the Board at any time. No shares have been repurchased under the new authorization as of the date of this filing.

ITEM 4.    MINE SAFETY DISCLOSURES

The information concerning mine safety violations and other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K (17 CFR 229.104) is included in Exhibit 95 to this Quarterly Report on Form 10-Q.

RESTRICTED STOCK AWARD AGREEMENT

GRANTEE: [Participant Name: First Name Middle Name Last Name] [Participant ID: Participant ID]

Congratulations! If you accept the terms of this Agreement, you will be granted an Award of EOG Resources, Inc. Restricted Stock as follows:

Date of Grant	[Grant Date: Month DD, YYYY]
Shares of Restricted Stock granted under this Award	[Granted: Shares Granted]

If you accept the terms of this Agreement, the Compensation Committee of the Board of EOG Resources, Inc. (the “Company”) hereby grants to you, the above-named Grantee, effective as of the Date of Grant set forth above, a Restricted Stock Award (the “Award”) in accordance with the terms set forth below.

General. This Restricted Stock Award Agreement (this “Agreement”) is governed by the terms and conditions of the EOG Resources, Inc. 2021 Omnibus Equity Compensation Plan (as may be amended from time to time, the “Plan”), which is hereby made a part of this Agreement. All capitalized terms that are not defined in this Agreement have the meanings ascribed to them under the Plan. Under the terms of this Agreement and the Plan, a Restricted Stock book entry will be maintained by the Company (or its agent) until you become vested in the shares of Restricted Stock. You will have voting rights with respect to the shares of Restricted Stock.

Vesting. Assuming your continuous employment with the Company or an Affiliate, this Award shall vest on the Vesting Date and the shares of Restricted Stock shall be released on the first business day following the Vesting Date (or as soon as administratively practicable thereafter, but no later than 60 days following such date).

Termination of Employment. In the event of Involuntary Termination for performance reasons, Termination for Cause, or voluntary termination prior to the Vesting Date, all shares of Restricted Stock awarded hereunder shall be forfeited and canceled. Further, if your employment with the Company or an Affiliate is otherwise terminated prior to the Vesting Date, this Award shall terminate and all shares of Restricted Stock awarded hereunder shall be forfeited and canceled, except as provided below.

Due to Death or Disability. If your employment with the Company or an Affiliate terminates due to death or Disability prior to the Vesting Date, all forfeiture restrictions on the shares of Restricted Stock awarded hereunder shall lapse and all shares shall be released to your beneficiary or you as soon as administratively practicable following the effective date of such termination (but no later than 60 days following such date).

Due to Involuntary Termination for Other than Performance Reasons. In the event of Involuntary Termination for any reason other than performance reasons prior to the Vesting Date, for each whole year that has passed prior to the effective date of your Involuntary Termination since the Date of Grant set forth above, 33% of the shares of Restricted Stock awarded hereunder (rounded down to the next whole share) shall be released to you as soon as administratively practicable following the effective date of such Involuntary Termination (but no later than 60 days following such date).

Due to a Change in Control. Upon the termination of your employment by the Company without Cause or by you for Good Reason during the two-year period following a Change in Control of the Company prior to the Vesting Date, all forfeiture restrictions on the shares of Restricted Stock awarded hereunder shall lapse as of the date of your termination and such shares shall be released to you as soon as administratively practicable following the date of your termination (but no later than 60 days following such date).

Dividends. Pursuant to Section 7.5 of the Plan, (i) dividends on unvested shares of Restricted Stock shall accrue and be credited by the Company for your benefit, and (ii) such dividends shall not be paid to you until (and to the extent) you become vested in such shares of Restricted Stock and shall be forfeited in the event of (and to the extent of) the forfeiture and cancellation of such shares of Restricted Stock pursuant to this Agreement.

Full Time and Attention. You agree to devote your full time and attention during normal working hours to the service of the Company. You shall not engage in any business or secondary employment that interferes with your obligations and responsibilities to the Company. Outside work must not be done on Company time and must not involve the use of Company resources. You further agree that during your employment with the Company you will not (1) engage in any business competitive with the business conducted by the Company; (2) render advice or services to, or otherwise assist, any other person, association, or entity who is engaged, directly or indirectly, in any business competitive with the business conducted by the Company; or (3) induce any employee of the Company to terminate employment with the Company or hire or assist in the hiring of any such employee by any person, association, or entity not affiliated with the Company.

Such information will hereinafter collectively be called “Confidential Information” and will include any and all items enumerated in the preceding sentence and coming within the scope of the business of the Company or any of its subsidiaries or affiliates as to which you had access, whether conceived or developed by others or by you alone or with others during the period of your service to the Company (as an employee or director), whether or not conceived or developed during regular working hours. Confidential Information can be intangible (e.g., is only maintained in the minds of Company personnel) or tangible (e.g., it has been reduced to a tangible medium, such as documents, drawings, memoranda, notes, records, files, correspondence, manuals, models, specifications, computer programs, email, voice mail, electronic databases, maps, and all other writings or materials of any type). You will not during your membership on the Board, nor during the Restricted Period, (a) disclose, directly or indirectly, any Confidential Information to any person, other than (i) the Company or personnel thereof, (ii) any person who, at the time of such disclosure, in your reasonable judgment, needs to know such Confidential Information and to whom you have been expressly authorized, in advance and in writing by an executive officer of the Company, to disclose such Confidential Information, or (iii) as otherwise required by applicable law and in all such cases only to the extent required and after prompt notice to the Company; or (b) use any Confidential Information, directly or indirectly, for your own benefit or for the benefit of any other person or entity.

Non-Competition. In consideration of the proprietary information you have received and will continue to receive from the Company and the other benefits and obligations provided under this Agreement, and to protect the Company’s Confidential Information (as defined above) and goodwill, you agree that during your membership on the Board and during the twelve (12) month period immediately following any termination of your membership on the Board (such periods of time, together, the “Restricted Period”), you will not in any capacity, for yourself or for others, directly or indirectly, unless expressly approved in advance by the Board (i) own any equity or other ownership interest in a Competitor (defined below), (ii) manage, operate, participate in, finance, or control a Competitor, or (iii) in a similar role or function as which you performed for the Company (whether prior to the execution of this Agreement or after the execution of this Agreement), work for, be employed by, engage in duties, provide services to, consult, or advise a Competitor. The term “Competitor” means any person, firm, entity, business, or organization that is engaged in, or is planning to engage in, the “Business” within the “Geographic Area”. Competitor expressly includes you acting on your own behalf; provided, however, that ownership of up to three percent (3%) of the issued and outstanding voting securities of any publicly traded entity shall not be deemed as engaging in the business of that entity solely by reason of such ownership of up to three percent (3%) of that entity’s voting securities.

For purposes of this Agreement, you acknowledge and agree (i) that the Company is primarily engaged in the exploration, development, and/or production of hydrocarbons and owns or operates producing oil and gas wells and hydrocarbon treating and transportation facilities, and (ii) that those activities, as well as any additional products, services, or business the Company provides or conducts during your membership on the Board, collectively constitute the “Business.”

The term “Geographic Area” means any oil and gas basin in which the Company is active (whether such basin is exploratory, in development or producing) or has been active during the 12-month period preceding the termination of your membership on the Board.

Code of Business Conduct and Ethics for Directors, Officers and Employees (as may be amended from time to time), specifically the provisions therein regarding conflicts of interest, outside business activities and corporate opportunities (as such provisions may be amended from time to time and including any successor provisions thereto), which provisions are incorporated herein by reference and shall be deemed to be part of this “Non-Competition” section.

Non-Solicitation. You agree that during the Restricted Period, you will not directly or indirectly:

(A)solicit (regardless of which party initiated contact), induce, or attempt to induce (or approach, authorize, solicit, hire, retain, or assist any person or entity for the foregoing purposes) any clients, customers, vendors, subcontractors, or suppliers of the Company or its affiliates, as the case may be, with whom you had business contact or as to whom you had access to Confidential Information or proprietary information, to cease or otherwise modify its doing business, in whole or in part, with or through the Company or its affiliates or to become a client or customer of any Competitor; or

(B)recruit, solicit, induce, or attempt to induce (regardless of which party initiated contact) any other person who is employed at the Company, who was employed by the Company during the 60-days prior to the termination of your membership on the Board, with whom you had business contact or as to whom you had access to Confidential Information or proprietary information, to (i) leave the employ of the Company, (ii) deviate from full-time employment and devotion of full-time effort in his or her employment with the Company, or (iii) otherwise directly or indirectly own, manage, operate, control, be employed by, perform any services for, consult with, solicit business for, participate in, or be connected with the ownership, management, operation, or control of any business, other than that of the Company, or assist any entity, in any manner, in doing any of the foregoing actions. Notwithstanding the foregoing, general solicitations not specifically targeting such restricted employees (such as through the placing of a classified ad in a newspaper) shall not be a breach of this provision.

Severability. If any provision of this Agreement is held by a court of law to be illegal, invalid, or unenforceable, (i) that provision shall be amended to achieve as nearly as possible the same effect as the original provision, and (ii) the legality, validity, and enforceability of the remaining provisions of this Agreement shall not be affected or impaired thereby.

Non-Disparagement. You agree you will not, during your membership on the Board or at any time thereafter, make any disparaging remarks about the Company or any of its employees, officers, directors, agents, or representatives, verbally or in writing, including, without limitation, (i) to the press and/or media, journalists of any kind, newspapers, periodicals, radio, television, cable and/or satellite reporters, programs or telecasts, or Internet media or (ii) posting on YouTube, Facebook, Twitter, Instagram, Snapchat, TikTok, blogs or other public forums. You also agree you will not, during your membership on the Board or at any time thereafter, otherwise take any action that could reasonably be anticipated to cause damage to the reputation, goodwill, or business of the Company or any of its employees, officers, directors, agents, or representatives. Notwithstanding the foregoing provision, nothing in this paragraph or this Agreement shall preclude you from responding truthfully to a valid subpoena, cooperating with a governmental agency in connection with any investigation it is conducting, voluntarily communicating with the Securities and Exchange Commission concerning possible securities laws violations, or taking any action otherwise required by law, legal process, or rules of professional conduct or permitted by this Agreement.

Delivery of Documents. By accepting the terms of this Agreement, you consent to the electronic delivery of documents related to your current or future participation in the Plan (including the Plan documents; this Agreement; any prospectus or other documents describing the terms and conditions of the Plan and this Award; and the Company’s annual report to stockholders, Annual Report on Form 10-K and definitive proxy statement), and you acknowledge that such electronic delivery may be made by the Company, in its sole discretion, by one or more of the following methods: (i) the posting of such documents on the Company’s intranet website or external website; (ii) the posting of such documents on the UBS Financial Services, Inc. website; (iii) the delivery of such documents via the UBS Financial Services, Inc. website; (iv) the posting of such documents to another Company intranet website or third party internet website accessible by you; or (v) delivery via electronic mail, by attaching such documents to such electronic email and/or including a link to such documents on a Company intranet website or external website or third party internet website accessible by you. Notwithstanding the foregoing, you also acknowledge that the Company may, in its sole discretion (and as an alternative to, or in addition to, electronic delivery) deliver a paper copy of any such documents to you. You further acknowledge that you may receive from the Company a paper copy of any documents delivered electronically at no cost to you by contacting the Company (Attention: Human Resources Department) by telephone or in writing.

Due to Cause. If you are removed from the Board for cause prior to the Vesting Date, this Award shall terminate and all Restricted Stock Units awarded hereunder shall be forfeited and canceled. For purposes of this Agreement, “cause” shall mean gross negligence or willful misconduct in the performance of your duties as a Director, or final conviction of a felony or of a misdemeanor involving moral turpitude.

Due to a Change in Control. If your membership on the Board terminates during the two-year period following a Change in Control of the Company prior to the Vesting Date, all forfeiture restrictions on the Restricted Stock Units awarded hereunder shall lapse as of the date of termination of your Board membership and all shares of Company common stock represented by the Restricted Stock Units shall be distributed to you as soon as administratively practicable following the effective date of termination of your Board membership, but no later than 60 days after such date; provided, however, that if the event constituting the Change in Control of the Company does not qualify as a change in effective ownership or control of the Company for purposes of Section 409A, then, pursuant to Section 12.2 of the Plan, such distribution shall be delayed until the earliest time that such distribution would be Permissible under Section 409A.

Deferral of Award. Subject to the foregoing and contingent on you remaining on the Board until the Vesting Date, if you have elected for your Restricted Stock Units to be treated upon vesting as “phantom” shares in accordance with the terms of the EOG Resources, Inc. 409A Deferred Compensation Plan (as amended, the “Deferral Plan”), then this Award shall, from the date that is 12 months from the Date of Grant, be governed by the terms of the Deferral Plan and this Agreement, and you will have no voting rights with respect to the Company common stock represented by such “phantom” shares until such time as shares of Company common stock are issued to you in accordance with the Deferral Plan.

Section 409A. The Plan and this Agreement are intended to meet the requirements of Section 409A, and shall be administered such that any payment, settlement, or deferrals of amounts hereunder shall not be subject to any excise penalty tax that may be imposed thereunder.

Exhibit 95

Mine Safety Disclosure Exhibit

    Under the Dodd-Frank Wall Street Reform and Consumer Protection Act and the related rules promulgated thereunder by the United States Securities and Exchange Commission (SEC), each operator of a coal or other mine is required to disclose certain mine safety matters in its periodic reports filed with the SEC.

EOG Resources, Inc. (EOG) has sand mining facilities in Texas and Wisconsin, which have supported EOG's exploration and development operations. EOG's sand mining operations are subject to regulation by the federal Mine Safety and Health Administration (MSHA) under the Federal Mine Safety and Health Act of 1977 (Mine Act). MSHA inspects mining facilities on a regular basis and issues citations and orders when it believes a violation has occurred under the Mine Act.

EOG was the operator of record of the following sand mining facilities during the quarter ended September 30, 2021:

•Hood County Sand Plant - Hood County, TX (MSHA ID 41-04696);

•Rawhide Sand Plant - Hood County, TX (MSHA ID 41-04777); and

•Chippewa Falls Sand Plant - Chippewa County, WI (MSHA ID 47-03624).

__________

During the quarter ended September 30, 2021, EOG did not receive any of the following from MSHA: (i) a citation for a violation of a mandatory health or safety standard that could significantly and substantially contribute to the cause and effect of a mine safety or health hazard under Section 104 of the Mine Act; (ii) an order issued under Section 104(b) of the Mine Act; (iii) a citation or order for unwarrantable failure to comply with mandatory health or safety standards under Section 104(d) of the Mine Act; (iv) written notice of a flagrant violation under Section 110(b)(2) of the Mine Act; (v) an imminent danger order issued under Section 107(a) of the Mine Act; (vi) any proposed assessments under the Mine Act; (vii) written notice of a pattern of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of mine health or safety hazards under Section 104(e) of the Mine Act; or (viii) written notice of the potential to have such a pattern. Moreover, during the quarter ended September 30, 2021, EOG did not experience a mining-related fatality.

In addition, as of September 30, 2021, EOG did not have any legal action pending before the Federal Mine Safety and Health Review Commission (Mine Commission), and did not have any legal actions instituted or resolved before the Mine Commission during the quarter ended September 30, 2021.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

General. The condensed consolidated financial statements of EOG Resources, Inc., together with its subsidiaries (collectively, EOG), included herein have been prepared by management without audit pursuant to the rules and regulations of the United States Securities and Exchange Commission (SEC). Accordingly, they reflect all normal recurring adjustments which are, in the opinion of management, necessary for a fair presentation of the financial results for the interim periods presented. Certain information and notes normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations. However, management believes that the disclosures included either on the face of the financial statements or in these notes are sufficient to make the interim information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in EOG's Annual Report on Form 10-K for the year ended December 31, 2020, filed on February 25, 2021 (EOG's 2020 Annual Report).

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The operating results for the three and nine months ended September 30, 2021, are not necessarily indicative of the results to be expected for the full year.

Effective January 1, 2021, EOG adopted the provisions of Accounting Standards Update (ASU) 2019-12, "Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes" (ASU 2019-12). ASU 2019-12 amends certain aspects of accounting for income taxes, including the removal of specific exceptions within existing U.S. GAAP related to the incremental approach for intraperiod tax allocation and updates to the general methodology for calculating income taxes in interim periods, among other changes. ASU 2019-12 also requires an entity to reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date, among other requirements. The effects of ASU 2019-12 applicable to EOG were all required on a prospective basis. There was no impact upon adoption of ASU 2019-12 to EOG's consolidated financial statements or related disclosures.

Recently Issued Accounting Standards. In March 2020, the Financial Accounting Standards Board (FASB) issued ASU 2020-04, "Reference Rate Reform (Topic 848)" (ASU 2020-04), which provides optional expedients and exceptions for accounting treatment of contracts which are affected by the anticipated discontinuation of the London InterBank Offered Rate (LIBOR) and other rates resulting from rate reform. Contract terms that are modified due to the replacement of a reference rate are not required to be remeasured or reassessed under relevant accounting standards. Early adoption is permitted. ASU 2020-04 covers certain contracts which reference these rates and that are entered into on or before December 31, 2022. EOG is evaluating the provisions of ASU 2020-04 and has not determined the full impact on its consolidated financial statements and related disclosures related to its $2.0 billion senior unsecured Revolving Credit Agreement.

Share-based Payment Arrangement [Abstract]

Stock-Based Compensation

Stock-Based Compensation

As more fully discussed in Note 7 to the Consolidated Financial Statements included in EOG's 2020 Annual Report, EOG maintains various stock-based compensation plans. Stock-based compensation expense is included on the Condensed Consolidated Statements of Income (Loss) and Comprehensive Income (Loss) based upon the job function of the employees receiving the grants as follows (in millions):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
Lease and Well	$	11	$	9	$	36	$	39

The Amended and Restated EOG Resources, Inc. 2008 Omnibus Equity Compensation Plan (2008 Plan) provided for grants of stock options, stock-settled stock appreciation rights (SARs), restricted stock and restricted stock units, performance units and other stock-based awards.

EOG's stockholders approved the EOG Resources, Inc. 2021 Omnibus Equity Compensation Plan (2021 Plan) at the 2021 Annual Meeting of Stockholders. Therefore, no further grants were made from the 2008 Plan from and after the April 29, 2021 effective date of the 2021 Plan. The 2021 Plan provides for grants of stock options, SARs, restricted stock and restricted stock units, restricted stock units with performance-based conditions (together with the performance units granted under the 2008 Plan, "Performance Units") and other stock-based awards, up to an aggregate maximum of 20 million shares of common stock, plus any shares that are subject to outstanding awards under the 2008 Plan as of April 29, 2021, that are subsequently canceled, forfeited, expire or are otherwise not issued or are settled in cash. Under the 2021 Plan, grants may be made to employees and non-employee members of EOG's Board of Directors (Board). EOG's policy is to issue shares related to 2021 Plan grants from previously authorized unissued shares or treasury shares to the extent treasury shares are available.

At September 30, 2021, approximately 17 million shares of common stock remained available for grant under the 2021 Plan.

Stock Options and Stock-Settled Stock Appreciation Rights and Employee Stock Purchase Plan. The fair value of stock option grants and SAR grants is estimated using the Hull-White II binomial option pricing model. The fair value of Employee Stock Purchase Plan (ESPP) grants is estimated using the Black-Scholes-Merton model. Stock-based compensation expense related to stock option, SAR and ESPP grants totaled $20 million and $23 million during the three months ended September 30, 2021 and 2020, respectively, and $39 million and $52 million during the nine months ended September 30, 2021 and 2020, respectively.

Weighted average fair values and valuation assumptions used to value stock option, SAR and ESPP grants during the nine-month periods ended September 30, 2021 and 2020 are as follows:

	Stock Options/SARs						ESPP
	Nine Months Ended September 30,						Nine Months Ended September 30,
	2021			2020			2021			2020
Weighted Average Fair Value of Grants	$	24.92		$	11.06		$	18.15		$	18.96
Expected Volatility	42.24		%	44.46		%	51.23		%	55.53		%
Risk-Free Interest Rate	0.50		%	0.21		%	0.07		%	0.83		%
Dividend Yield	2.25		%	3.27		%	2.88		%	2.35		%
Expected Life	5.2 years			5.2 years			0.5 years			0.5 years

Expected volatility is based on an equal weighting of historical volatility and implied volatility from traded options in EOG's common stock. The risk-free interest rate is based upon United States Treasury yields in effect at the time of grant. The expected life is based upon historical experience and contractual terms of stock option, SAR and ESPP grants.

The following table sets forth stock option and SAR transactions for the nine-month periods ended September 30, 2021 and 2020 (stock options and SARs in thousands):

	Nine Months Ended September 30, 2021			Nine Months Ended September 30, 2020
	Number of Stock Options/SARs	Weighted Average Exercise Price		Number of Stock Options/SARs	Weighted Average Exercise Price
Outstanding at January 1	10,186	$	84.08	9,395	$	94.53
Granted	1,976	81.66		1,993	37.62

Exercisable at September 30 (4)	6,906	$	92.39	6,389	$	96.53

(1)The total intrinsic value of stock options/SARs exercised during the nine months ended September 30, 2021 and 2020 was $8 million and $0.4 million, respectively. The intrinsic value is based upon the difference between the market price of EOG's common stock on the date of exercise and the exercise price of the stock options/SARs.

(2)The total intrinsic value of stock options/SARs outstanding at September 30, 2021 and 2020 was $95 million and $0.01 million, respectively. At September 30, 2021 and 2020, the weighted average remaining contractual life was 4.3 years and 4.5 years, respectively.

(3)The total intrinsic value of stock options/SARs vested or expected to vest at September 30, 2021 and 2020 was $90 million and $0.01 million, respectively. At September 30, 2021 and 2020, the weighted average remaining contractual life was 4.3 years and 4.5 years, respectively.

(4)The total intrinsic value of stock options/SARs exercisable at September 30, 2021 and 2020 was $38 million and zero, respectively. At September 30, 2021 and 2020, the weighted average remaining contractual life was 3.2 years and 3.4 years, respectively.

At September 30, 2021, unrecognized compensation expense related to non-vested stock option, SAR and ESPP grants totaled $69 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 2.3 years.

Restricted Stock and Restricted Stock Units. Employees may be granted restricted (non-vested) stock and/or restricted stock units without cost to them. Stock-based compensation expense related to restricted stock and restricted stock units totaled $20 million and $4 million for the three months ended September 30, 2021 and 2020, respectively, and $65 million and $53 million for the nine months ended September 30, 2021 and 2020, respectively.

The following table sets forth restricted stock and restricted stock unit transactions for the nine-month periods ended September 30, 2021 and 2020 (shares and units in thousands):

	Nine Months Ended September 30, 2021			Nine Months Ended September 30, 2020
	Number of Shares and Units	Weighted Average Grant Date Fair Value		Number of Shares and Units	Weighted Average Grant Date Fair Value
Outstanding at January 1	4,742	$	74.97	4,546	$	90.16
Granted	1,409	81.44		1,440	38.16
Released (1)	(1,321)	101.63		(1,139)	85.94
Forfeited	(65)	68.49		(63)	90.00
Outstanding at September 30 (2)	4,765	$	69.58	4,784	$	75.51

(1)The total intrinsic value of restricted stock and restricted stock units released during the nine months ended September 30, 2021 and 2020 was $104 million and $45 million, respectively. The intrinsic value is based upon the closing price of EOG's common stock on the date the restricted stock and restricted stock units are released.

(2)The total intrinsic value of restricted stock and restricted stock units outstanding at September 30, 2021 and 2020 was $383 million and $172 million, respectively.

At September 30, 2021, unrecognized compensation expense related to restricted stock and restricted stock units totaled $224 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 1.8 years.

Performance Units. EOG grants Performance Units annually to its executive officers without cost to them. As more fully discussed in the grant agreements, the performance metric applicable to the Performance Units is EOG's total shareholder return over a three-year performance period relative to the total shareholder return of a designated group of peer companies (Performance Period). Upon the application of the performance multiple at the completion of the Performance Period, a minimum of 0% and a maximum of 200% of the Performance Units granted could be outstanding. The fair value of the Performance Units is estimated using a Monte Carlo simulation. Stock-based compensation expense related to the Performance Unit grants totaled $11 million and $6 million for the three months ended September 30, 2021 and 2020, respectively, and $13 million and $8 million for the nine months ended September 30, 2021 and 2020, respectively.

The following table sets forth the Performance Unit transactions for the nine-month periods ended September 30, 2021 and 2020 (units in thousands):

	Nine Months Ended September 30, 2021				Nine Months Ended September 30, 2020
	Number of Units		Weighted Average Grant Date Fair Value		Number of Units	Weighted Average Grant Date Fair Value
Outstanding at January 1	613		$	88.38	598	$	103.91
Granted	222		90.94		172	42.77
Granted for Performance Multiple (1)	19		113.81		66	119.10
Released (2)	(175)		113.06		(223)	103.87
Forfeited	—		—		—	—
Outstanding at September 30 (3)	679	(4)	$	83.59	613	$	88.38

(1)Upon completion of the Performance Period for the Performance Units granted in 2017 and 2016, a performance multiple of 125% and 150%, respectively, was applied to each of the grants resulting in additional grants of Performance Units in February 2021 and February 2020, respectively.

(2)The total intrinsic value of Performance Units released was $13 million for both the nine months ended September 30, 2021 and 2020. The intrinsic value is based upon the closing price of EOG's common stock on the date the Performance Units are released.

(3)The total intrinsic value of Performance Units outstanding at September 30, 2021 and 2020 was approximately $55 million and $22 million, respectively.

(4)Upon the application of the relevant performance multiple at the completion of each of the remaining Performance Periods, a minimum of zero and a maximum of 1,358 Performance Units could be outstanding.

At September 30, 2021, unrecognized compensation expense related to Performance Units totaled $15 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 2.1 years.

Debt Disclosure [Abstract]

Long-Term Debt and Common Stock

Long-Term Debt and Common Stock

Long-Term Debt. EOG had no outstanding commercial paper borrowings at September 30, 2021 and December 31, 2020, and did not utilize any commercial paper borrowings during the nine months ended September 30, 2021 and 2020.

EOG currently has a $2.0 billion senior unsecured Revolving Credit Agreement (Agreement) with domestic and foreign lenders (Banks). The Agreement has a scheduled maturity date of June 27, 2024, and includes an option for EOG to extend, on up to two occasions, the term for successive one-year periods subject to certain terms and conditions. The Agreement (i) commits the Banks to provide advances up to an aggregate principal amount of $2.0 billion at any one time outstanding, with an option for EOG to request increases in the aggregate commitments to an amount not to exceed $3.0 billion, subject to certain terms and conditions and (ii) includes a swingline subfacility and a letter of credit subfacility. Advances under the Agreement will accrue interest based, at EOG's option, on either LIBOR plus an applicable margin (Eurodollar rate) or the base rate (as defined in the Agreement) plus an applicable margin. The Agreement contains representations, warranties, covenants and events of default that EOG believes are customary for investment-grade, senior unsecured commercial bank credit agreements, including a financial covenant for the maintenance of a ratio of total debt-to-capitalization (as such terms are defined in the Agreement) of no greater than 65%. At September 30, 2021, EOG was in compliance with this financial covenant. At September 30, 2021 and December 31, 2020, there were no borrowings or letters of credit outstanding under the Agreement. The Eurodollar rate and base rate (inclusive of the applicable margin), had there been any amounts borrowed under the Agreement at September 30, 2021, would have been 0.98% and 3.25%, respectively.

On February 1, 2021, EOG repaid upon maturity the $750 million aggregate principal amount of its 4.100% Senior Notes due 2021.

Common Stock. On February 25, 2021, EOG's Board increased the quarterly cash dividend on the common stock from the previous $0.375 per share to $0.4125 per share, effective beginning with the dividend paid on April 30, 2021, to stockholders of record as of April 16, 2021. On May 6, 2021, EOG's Board declared a special cash dividend on the common stock of $1.00 per share in addition to a quarterly dividend of $0.4125 per share. Both the special cash dividend and the quarterly cash dividend were paid on July 30, 2021 to stockholders of record as of July 16, 2021.

On November 4, 2021, EOG's Board (i) increased the quarterly cash dividend on the common stock from the previous $0.4125 per share to $0.75 per share, effective beginning with the dividend to be paid on January 28, 2022, to stockholders of record as of January 14, 2022, (ii) declared a second special cash dividend on the common stock of $2.00 per share, payable on December 30, 2021, to stockholders of record as of December 15, 2021, (iii) established a new share repurchase authorization to allow for the repurchase by EOG of up to $5 billion of the common stock and (iv) revoked and terminated the share repurchase authorization established by the Board in September 2001.

Fair Value Measurements

Recurring Fair Value Measurements. As more fully discussed in Note 13 to the Consolidated Financial Statements included in EOG's 2020 Annual Report, certain of EOG's financial and nonfinancial assets and liabilities are reported at fair value on the Condensed Consolidated Balance Sheets. The following table provides fair value measurement information within the fair value hierarchy for certain of EOG's financial assets and liabilities carried at fair value on a recurring basis at September 30, 2021 and December 31, 2020 (in millions):

See Note 12 for the balance sheet amounts and classification of EOG's financial derivative instruments at September 30, 2021 and December 31, 2020.

The estimated fair value of commodity derivative contracts was based upon forward commodity price curves based on quoted market prices. Commodity derivative contracts were valued by utilizing an independent third-party derivative valuation provider who uses various types of valuation models, as applicable.

Non-Recurring Fair Value Measurements. The initial measurement of asset retirement obligations at fair value is calculated using discounted cash flow techniques and based on internal estimates of future retirement costs associated with property, plant and equipment. Significant Level 3 inputs used in the calculation of asset retirement obligations include plugging costs and reserve lives. A reconciliation of EOG's asset retirement obligations is presented in Note 6.

When circumstances indicate that proved oil and gas properties may be impaired, EOG compares expected undiscounted future cash flows at a depreciation, depletion and amortization group level to the unamortized capitalized cost of the asset. If the expected undiscounted future cash flows, based on EOG's estimate of (and assumptions regarding) significant Level 3 inputs, including future crude oil, NGLs and natural gas prices, operating costs, development expenditures, anticipated production from proved reserves and other relevant data, are lower than the unamortized capitalized cost, the capitalized cost is reduced to fair value. Fair value is generally calculated using the Income Approach described in the Fair Value Measurement Topic of the Accounting Standards Codification. In certain instances, EOG utilizes accepted offers from third-party purchasers as the basis for determining fair value.

EOG utilized average prices per acre from comparable market transactions and estimated discounted cash flows as the basis for determining the fair value of unproved and proved properties, respectively, received in non-cash property exchanges. See Note 4.

Fair Value Disclosures. EOG's financial instruments, other than commodity derivative contracts, consist of cash and cash equivalents, accounts receivable, accounts payable and current and long-term debt. The carrying values of cash and cash equivalents, accounts receivable and accounts payable approximate fair value.

At September 30, 2021 and December 31, 2020, respectively, EOG had outstanding $4,890 million and $5,640 million aggregate principal amount of senior notes, which had estimated fair values at such dates of approximately $5,609 million and $6,505 million, respectively. The estimated fair value of debt was based upon quoted market prices and, where such prices were not available, other observable (Level 2) inputs regarding interest rates available to EOG at the end of each respective period.

Risk Management Activities

Risk Management Activities

Commodity Price Risk. As more fully discussed in Note 12 to the Consolidated Financial Statements included in EOG's 2020 Annual Report, EOG engages in price risk management activities from time to time. These activities are intended to manage EOG's exposure to fluctuations in commodity prices for crude oil, NGLs and natural gas. EOG utilizes financial commodity derivative instruments, primarily price swap, option, swaption, collar and basis swap contracts, as a means to manage this price risk. EOG has not designated any of its financial commodity derivative contracts as accounting hedges and, accordingly, accounts for financial commodity derivative contracts using the mark-to-market accounting method.

Commodity Derivative Contracts. Presented below is a comprehensive summary of EOG's financial commodity derivative contracts as of September 30, 2021. Crude oil and NGL volumes are presented in thousand barrels per day (MBbld) and prices are presented in dollars per barrel ($/Bbl). Natural gas volumes are presented in million British Thermal Units per day (MMBtud) and prices are presented in dollars per million British Thermal Units ($/MMBtu).

(2)    The current portion of Liabilities from Price Risk Management Activities consists of gross liabilities of $474 million, partially offset by collateral posted with counterparties of $236 million, at September 30, 2021.

(3)    The noncurrent portion of Liabilities from Price Risk Management Activities consists of gross liabilities of $153 million, partially offset by collateral posted with counterparties of $72 million, at September 30, 2021.

Credit Risk. Notional contract amounts are used to express the magnitude of a financial derivative. The amounts potentially subject to credit risk, in the event of nonperformance by the counterparties, are equal to the fair value of such contracts (see Note 11). EOG evaluates its exposures to significant counterparties on an ongoing basis, including those arising from physical and financial transactions. In some instances, EOG renegotiates payment terms and/or requires collateral, parent guarantees or letters of credit to minimize credit risk.All of EOG's derivative instruments are covered by International Swap Dealers Association Master Agreements (ISDAs) with counterparties. The ISDAs may contain provisions that require EOG, if it is the party in a net liability position, to post collateral when the amount of the net liability exceeds the threshold level specified for EOG's then-current credit ratings. In addition, the ISDAs may also provide that as a result of certain circumstances, including certain events that cause EOG's credit ratings to become materially weaker than its then-current ratings, the counterparty may require all outstanding derivatives under the ISDAs to be settled immediately. See Note 11 for the aggregate fair value of all derivative instruments that were in a net liability position at September 30, 2021 and a net asset position at December 31, 2020. EOG had $308 million of collateral posted and no collateral held at September 30, 2021, and had no collateral posted or held at December 31, 2020.
