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, 2022, filed on February 23, 2023 (EOG's 2022 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 months ended March 31, 2023, are not necessarily indicative of the results to be expected for the full year.

Recently Issued Accounting Standards. In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (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 were entered into on or before December 31, 2022. In December 2022, the FASB issued ASU 2022-06, "Reference Rate Reform (Topic 848)" (ASU 2022-06), which deferred the sunset date of Topic 848 until December 31, 2024. EOG has evaluated the provisions of ASU 2020-04 and ASU 2022-06 and has concluded that their application will not have a material impact on EOG's 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 2022 Annual Report, EOG maintains various stock-based compensation plans. Stock-based compensation expense is included on the Condensed Consolidated Statements of Income and Comprehensive Income based upon the job function of the employees receiving the grants as follows (in millions):

	Three Months Ended March 31,
	2023		2022
Lease and Well	$	12	$	13
Gathering and Processing Costs	1		1
Exploration Costs	5		5
General and Administrative	16		16
Total	$	34	$	35

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 Amended and Restated EOG Resources, Inc. 2008 Omnibus Equity Compensation Plan (2008 Plan) from and after the April 29, 2021 effective date of the 2021 Plan. The 2021 Plan provides for grants of stock options, stock-settled stock appreciation rights (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 were 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).

At March 31, 2023, approximately 16 million common shares remained available for grant under the 2021 Plan. EOG's policy is to issue shares related to the 2021 Plan grants from previously authorized unissued shares or treasury shares to the extent treasury shares are available.

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 $6 million and $8 million during the three months ended March 31, 2023 and 2022, respectively.

EOG did not grant any stock options or SARs during the three-month period ended March 31, 2023. Weighted average fair values and valuation assumptions used to value stock options and SARs granted during the three-month period ended March 31, 2022 and ESPP grants during the three-month periods ended March 31, 2023 and 2022 are as follows:

	Stock Options/SARs			ESPP
	Three Months Ended March 31,			Three Months Ended March 31,
	2022			2023			2022
Weighted Average Fair Value of Grants	$	28.30		$	32.31		$	23.07
Expected Volatility	42.20		%	42.97		%	39.72		%
Risk-Free Interest Rate	0.89		%	4.66		%	0.22		%
Dividend Yield	3.28		%	2.47		%	3.32		%
Expected Life	5.3 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.

Exercisable at March 31 (4)	2,294	$	84.89	3,886	$	101.26

(1)The total intrinsic value of stock options/SARs exercised during the three months ended March 31, 2023 and 2022 was $8 million and $62 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 March 31, 2023 and 2022 was $155 million and $277 million, respectively. At March 31, 2023 and 2022, the weighted average remaining contractual life was 3.9 years and 4.3 years, respectively.

(3)The total intrinsic value of stock options/SARs vested or expected to vest at March 31, 2023 and 2022 was $149 million and $260 million, respectively. At March 31, 2023 and 2022, the weighted average remaining contractual life was 3.8 years and 4.3 years, respectively.

(4)The total intrinsic value of stock options/SARs exercisable at March 31, 2023 and 2022 was $74 million and $82 million, respectively. At both March 31, 2023 and 2022, the weighted average remaining contractual life was 2.9 years.

At March 31, 2023, unrecognized compensation expense related to non-vested stock option, SAR and ESPP grants totaled $28 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 1.1 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 $25 million for each of the three months ended March 31, 2023 and 2022.

Outstanding at March 31 (2)	4,069	$	81.33	3,944	$	65.30

(1)The total intrinsic value of restricted stock and restricted stock units released during the three months ended March 31, 2023 and 2022 was $4 million and $81 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 March 31, 2023 and 2022 was $466 million and $470 million, respectively.

At March 31, 2023, unrecognized compensation expense related to restricted stock and restricted stock units totaled $261 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 1.6 years.

Performance Units. EOG grants Performance Units annually to its executive officers without cost to them. For the grants made prior to September 2022, as more fully discussed in the grant agreements, the applicable performance metric is EOG's total shareholder return (TSR) over a three-year performance period relative to the TSR over the same period of a designated group of peer companies. Upon the application of the applicable performance multiple at the completion of the three-year performance period, a minimum of 0% and a maximum of 200% of the Performance Units granted could be outstanding.

For the grants made beginning in September 2022, as more fully discussed in the grant agreements, the applicable performance metrics are 1) EOG's TSR over a three-year performance period relative to the TSR over the same period of a designated group of peer companies and 2) EOG's average return on capital employed (ROCE) over the three-year performance period. At the end of the three-year performance period, a performance multiple based on EOG's relative TSR ranking will be determined, with a minimum performance multiple of 0% and a maximum performance multiple of 200%. A specified modifier ranging from -70% to +70% will then be applied to the performance multiple based on EOG's average ROCE over the three-year performance period, provided that in no event shall the performance multiple, after applying the ROCE modifier, be less than 0% or exceed 200%. Furthermore, if EOG's TSR over the three-year performance period is negative (i.e., less than 0%), the performance multiple will be capped at 100%, regardless of EOG's relative TSR ranking or three-year average ROCE.

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 $3 million and $2 million for the three months ended March 31, 2023 and 2022, respectively.

10.    Long-Term Debt and Common Stock

Long-Term Debt. EOG had no outstanding commercial paper borrowings at March 31, 2023 and December 31, 2022, and did not utilize any commercial paper borrowings during the three months ended March 31, 2023 and 2022.

On March 15, 2023, EOG repaid upon maturity the $1,250 million aggregate principal amount of its 2.625% Senior Notes due 2023.

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 March 31, 2023, EOG was in compliance with this financial covenant. At March 31, 2023 and December 31, 2022, 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 March 31, 2023, would have been 5.76% and 8.0%, respectively.

Common Stock. In November 2021, the Board established a new share repurchase authorization that allows for the repurchase by EOG of up to $5 billion of its common stock (November 2021 Authorization). Under the November 2021 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 is at the discretion of EOG's management and depends on a variety of factors, including the trading price of EOG's common stock, corporate and regulatory requirements, and other market and economic conditions. Repurchased shares are held as treasury shares and are available for general corporate purposes. The November 2021 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. During the three months ended March 31, 2023, EOG repurchased 2.9 million shares of common stock for approximately $310 million (inclusive of transaction fees and commissions) pursuant to the November 2021 Authorization. As of March 31, 2023, approximately $4.7 billion remained available for repurchases under the November 2021 Authorization.

On February 23, 2023, the Board declared a quarterly cash dividend on the common stock of $0.825 per share, paid on April 28, 2023, to stockholders of record as of April 14, 2023. The Board also declared on such date a special cash dividend on the common stock of $1.00 per share, paid on March 30, 2023, to stockholders of record as of March 16, 2023.

On May 4, 2023, the Board declared a quarterly cash dividend on the common stock of $0.825 per share to be paid on July 31, 2023, to stockholders of record as of July 17, 2023.

11.    Fair Value Measurements

Recurring Fair Value Measurements. As more fully discussed in Note 13 to the Consolidated Financial Statements included in EOG's 2022 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 March 31, 2023 and December 31, 2022 (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
At March 31, 2023
Financial Assets:
Natural Gas Swaps	$	—	$	21	$	—	$	21
Natural Gas Basis Swaps	—		12		—		12
Financial Liabilities:
Crude Oil Swaps	—		49		—		49
Natural Gas Swaps	—		391		—		391
At December 31, 2022
Financial Assets:
Natural Gas Basis Swaps	$	—	$	29	$	—	$	29
Financial Liabilities:
Natural Gas Swaps	—		703		—		703
Crude Oil Swaps	—		190		—		190

See Note 12 for the balance sheet amounts and classification of EOG's financial commodity derivative instruments at March 31, 2023 and December 31, 2022.

The estimated fair value of financial commodity derivative contracts was based upon forward commodity price curves based on quoted market prices. Financial 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 is 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, natural gas liquids (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 FASB's 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 financial 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 March 31, 2023 and December 31, 2022, respectively, EOG had outstanding $3,640 million and $4,890 million aggregate principal amount of senior notes, which had estimated fair values at such dates of approximately $3,592 million and $4,740 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 2022 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.

Financial Commodity Derivative Contracts. Presented below is a comprehensive summary of EOG's financial commodity derivative contracts settled during the three-month period ended March 31, 2023 (closed) and outstanding as of March 31, 2023. Crude oil volumes are presented in thousand barrels per day (MBbld) and prices are presented in dollars per barrel ($/Bbl).

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 both March 31, 2023 and December 31, 2022. EOG had no collateral posted and no collateral held at March 31, 2023. EOG had $324 million of collateral posted and no collateral held at December 31, 2022. EOG had no collateral posted and no collateral held at May 3, 2023.

13.  Acquisitions and Divestitures

During the three months ended March 31, 2023, EOG paid cash of $135 million, primarily to acquire a gathering and processing system in the Powder River Basin. Additionally, during the three months ended March 31, 2023, EOG recognized net gains on asset dispositions of $69 million and received proceeds of $92 million, primarily due to the sale of EOG's equity interest in ammonia plant investments in Trinidad, along with certain legacy assets in the Texas Panhandle.

During the three months ended March 31, 2022, EOG recognized net gains on asset dispositions of $25 million and received proceeds of $121 million primarily due to the sale of certain legacy natural gas assets in the Rocky Mountain area.

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 maximize long-term 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.

Commodity Prices. Prices for crude oil and condensate, natural gas liquids (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.

For the first three months of 2023, the average U.S. New York Mercantile Exchange (NYMEX) crude oil and natural gas prices were $76.11 per barrel and $3.43 per million British thermal units (MMBtu), respectively, representing decreases of 19% and 30%, respectively, from the average NYMEX prices for the same period in 2022. 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.

Inflation Considerations; Availability of Materials, Labor & Services. Beginning in the second half of 2021 and continuing through the first three months of 2023, EOG, similar to other companies in its industry, has experienced inflationary pressures on its operating and capital costs - namely the costs of fuel, steel (i.e., wellbore tubulars and facilities manufactured using steel), labor and drilling and completion services. Such inflationary pressures have resulted from (i) supply chain disruptions caused by the COVID-19 pandemic and the resulting limited availability of certain materials and products manufactured using such materials; (ii) increased demand for fuel and steel; (iii) increased demand for drilling and completion services coupled with a limited number of available service providers, resulting in increased competition for such services among EOG and other companies in its industry; (iv) labor shortages; and (v) other factors, including the ongoing conflict between Russia and the Ukraine which began in late February 2022. EOG currently expects such inflationary pressures and contributing factors to continue in 2023.

Such inflationary pressures on EOG's operating costs have, in turn, impacted its cash flows and results of operations. However, by virtue of its continued focus on increasing its drilling, completion and operating efficiencies and improving the performance of its wells, as well as the flexibility provided by its multi-basin drilling portfolio, EOG has, to date, been able to largely offset such impacts. EOG currently expects such inflationary pressures to result in an increase of approximately 10 percent in its fiscal year 2023 well costs (i.e., its costs for drilling, completions and well-site facilities) versus fiscal year 2022. Accordingly, such increase in EOG's fiscal year 2023 well costs did not have a material impact on EOG's first quarter 2023 cash flows, and EOG currently does not expect such increase to have a material impact on its full-year 2023 cash flows. Further, such inflationary pressures and the factors contributing to such inflationary pressures (described above) have not, to date, impacted EOG's results of operations, liquidity, capital resources, cash requirements or financial position or its ability to conduct its day-to-day drilling, completion and production operations.

-20-

The initiatives EOG has undertaken (and continues to undertake) to increase its drilling, completion and operating efficiencies and improve the performance of its wells and, in turn, mitigate such inflationary pressures, include (among others): (i) EOG's downhole drilling motor program, which has resulted in increased footage drilled per day and, in turn, reduced drilling times; (ii) enhanced techniques for completing its wells, which has resulted in increased footage completed per day and pumping hours per day; and (iii) EOG's self-sourced sand program, which has resulted in continued cost savings for the sand utilized in its well completion operations. In addition, EOG enters into agreements with its service providers from time to time, when available and advantageous, to secure the costs and availability of certain drilling and completion services it utilizes as part of its operations.

EOG plans to continue with these initiatives and actions, though there can be no assurance that such efforts will offset, largely or at all, the impacts of any future inflationary pressures on EOG's operating costs, cash flows and results of operations. Further, there can be no assurance that the factors contributing to any future inflationary pressures will not impact EOG's ability to conduct its future day-to-day drilling, completion and production operations.

Climate Change. For discussion of climate change matters and related regulatory matters, including potential developments related to climate change and the potential impacts and risks of such developments on EOG, see ITEM 1A. Risk Factors, and the related discussion in ITEM 1. Business - Regulation, of EOG's Annual Report on Form 10-K for the year ended December 31, 2022, filed on February 23, 2023 (EOG's 2022 Annual Report). EOG will continue to monitor and assess any climate change-related developments that could impact EOG and the oil and gas industry, to determine the impact on its business and operations, and take appropriate actions where necessary.

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 plays and natural gas plays.

During the first three months of 2023, EOG continued to focus on increasing drilling, completion and operating efficiencies, to improve well performance and, as is further discussed above, to mitigate inflationary pressures on its operating and capital costs (e.g., costs for fuel and tubulars). 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 or bolt-on acquisitions. On a volumetric basis, as calculated using a 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 73% and 75% of EOG's United States production during the first three months of 2023 and 2022, respectively. During the first three months of 2023, 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.

Trinidad. In the Republic of Trinidad and Tobago (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), 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 (NGC), and crude oil and condensate which is sold to Heritage Petroleum Company Limited (Heritage).

EOG expects to commence drilling in June 2023 from the recently completed platform in the Modified U(a) Block. EOG expects to complete three development wells and two exploratory wells from this platform in 2023. EOG also expects to commence drilling one exploratory well in the South East Coast Consortium Block in December 2023. Additionally, EOG completed the design phase for the platform and related facilities in the Mento Area and expects to make significant construction progress in 2023.

Also, in February 2023, EOG sold its entire equity interest in its ammonia plant investments.

Other International. In November 2021, a subsidiary of EOG was granted an exploration permit for the WA-488-P Block, located offshore Western Australia. In the first three months of 2023, EOG continued to prepare for the drilling of an exploration well which is expected to commence in 2024, subject to statutory approvals and equipment availability.

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.

2023 Capital and Operating Plan. Total 2023 capital expenditures are estimated to range from approximately $5.8 billion to $6.2 billion, including facilities and gathering, processing, transportation and other expenditures, and excluding acquisitions, non-cash transactions and exploration costs. 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 be focused on United States drilling activity in the Delaware Basin, Eagle Ford play, Rocky Mountain area and Dorado gas play 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 to mitigate inflationary pressures on its operating and capital costs (e.g., costs for fuel and tubulars) through efficiency gains; see the above related discussion. Full-year 2023 total crude oil, NGLs and natural gas production is expected to increase modestly versus 2022. In addition, EOG plans to continue to spend a portion of its anticipated 2023 capital expenditures on leasing acreage, evaluating new prospects, transportation infrastructure and environmental projects.

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 13% and 17% at March 31, 2023 and December 31, 2022, respectively. As used in this calculation, total capitalization represents the sum of total current and long-term debt and total stockholders' equity.

At March 31, 2023, EOG maintained a strong financial and liquidity position, including $5.0 billion of cash and cash equivalents on hand and $2.0 billion of availability under its senior unsecured revolving credit facility.

On March 15, 2023, EOG repaid upon maturity the $1,250 million aggregate principal amount of its 2.625% Senior Notes due 2023.

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.

Cash Return Framework. EOG maintains quantitative guidance as part of its cash return framework - specifically, a commitment to return a minimum of 60% of annual net cash provided by operating activities before certain balance sheet-related changes, less total capital expenditures, to stockholders, through a combination of quarterly dividends, special dividends and share repurchases. For discussion regarding our payment of dividends, see ITEM 1A, Risk Factors, and ITEM 5, Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities, of EOG's 2022 Annual Report. For discussion regarding our share repurchases conducted during the first three months of 2023 and our share repurchase authorization, see Part II, Item 2. Unregistered Sales of Equity Securities and Use of Proceeds, in this Quarterly Report on Form 10-Q.

Dividend Declarations. On February 23, 2023, EOG's Board of Directors (Board) declared a quarterly cash dividend on the common stock of $0.825 per share, paid on April 28, 2023, to stockholders of record as of April 14, 2023. The Board also declared on such date a special dividend on the common stock of $1.00 per share, paid on March 30, 2023, to stockholders of record as of March 16, 2023.

On May 4, 2023, the Board declared a quarterly cash dividend on the common stock of $0.825 per share to be paid on July 31, 2023, to stockholders of record as of July 17, 2023.

-22-

Share Repurchases. In November 2021, the Board established a new share repurchase authorization that allows for the repurchase by EOG of up to $5 billion of its common stock (November 2021 Authorization). Under the November 2021 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 is at the discretion of EOG's management and depends on a variety of factors, including the trading price of EOG's common stock, corporate and regulatory requirements, and other market and economic conditions. Repurchased shares are held as treasury shares and are available for general corporate purposes. The November 2021 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. During the three months ended March 31, 2023, EOG repurchased 2.9 million shares of common stock for approximately $310 million (inclusive of transaction fees and commissions) pursuant to the November 2021 Authorization. As of March 31, 2023, approximately $4.7 billion remained available for repurchases under the November 2021 Authorization.

Results of Operations

The following review of operations for the three months ended March 31, 2023 and 2022 should be read in conjunction with the Condensed Consolidated Financial Statements of EOG and notes thereto included in this Quarterly Report on Form 10-Q.

Three Months Ended March 31, 2023 vs. Three Months Ended March 31, 2022

Operating Revenues and Other. During the first quarter of 2023, operating revenues increased $2,061 million, or 52%, to $6,044 million from $3,983 million for the same period of 2022. Total wellhead revenues, which are revenues generated from sales of EOG's production of crude oil and condensate, NGLs and natural gas, for the first quarter of 2023 decreased $1,097 million, or 21%, to $4,189 million from $5,286 million for the same period of 2022. EOG recognized net gains on the mark-to-market of financial commodity derivative contracts of $376 million for the first quarter of 2023 compared to net losses of $2,820 million for the same period of 2022. Gathering, processing and marketing revenues for the first quarter of 2023 decreased $79 million, or 5%, to $1,390 million from $1,469 million for the same period of 2022. Net gains on asset dispositions were $69 million for the first quarter of 2023 compared to net gains of $25 million for the same period of 2022.

Wellhead crude oil and condensate revenues for the first quarter of 2023 decreased $707 million, or 18%, to $3,182 million from $3,889 million for the same period of 2022. The decrease was due to a lower composite average price ($774 million), partially offset by an increase of 7.6 MBbld, or 2%, in wellhead crude oil and condensate production ($67 million). Increased production was primarily in the Permian Basin, partially offset by decreased production in the Eagle Ford play and the Rocky Mountain area. EOG's composite wellhead crude oil and condensate price for the first quarter of 2023 decreased 20% to $77.26 per barrel compared to $96.00 per barrel for the same period of 2022.

NGL revenues for the first quarter of 2023 decreased $191 million, or 28%, to $490 million from $681 million for the same period of 2022 due to a lower composite average price ($272 million), partially offset by an increase of 21.9 MBbld, or 12%, in NGL deliveries ($81 million). Increased production was primarily from the Permian Basin. EOG's composite NGL price for the first quarter of 2023 decreased 35% to $25.67 per barrel compared to $39.77 per barrel for the same period of 2022.

Wellhead natural gas revenues for the first quarter of 2023 decreased $199 million, or 28%, to $517 million from $716 million for the same period of 2022. The decrease was due to a lower average composite price ($293 million), partially offset by an increase in natural gas deliveries ($94 million). Natural gas deliveries for the first quarter of 2023 increased 181 MMcfd, or 12%, compared to the same period of 2022 due primarily to increased production of associated natural gas from the Permian Basin and higher deliveries in the Dorado gas play, partially offset by lower natural gas deliveries in Trinidad, lower natural gas volumes due to the sale of certain legacy natural gas assets in the Rocky Mountain area in the first quarter of 2022 and decreased production of associated natural gas from the Eagle Ford play. EOG's composite wellhead natural gas price for the first quarter of 2023 decreased 36% to $3.51 per Mcf compared to $5.46 per Mcf for the same period of 2022.

During the first quarter of 2023, EOG recognized net gains on the mark-to-market of financial commodity derivative contracts of $376 million compared to net losses of $2,820 million for the same period of 2022. During the first quarter of 2023, net cash paid for settlements of financial commodity derivative contracts was $123 million compared to net cash paid for settlements of financial commodity derivative contracts of $296 million for the same period of 2022.

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 primarily 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 first quarter of 2023 decreased $157 million as compared to the same period of 2022 primarily due to lower margins on crude oil and natural gas marketing activities.

-26-

Operating and Other Expenses.  For the first quarter of 2023, operating expenses of $3,472 million were $35 million higher than the $3,437 million incurred during the first quarter of 2022.  The following table presents the costs per barrel of oil equivalent (Boe) for the three-month periods ended March 31, 2023 and 2022:

	Three Months Ended March 31,
	2023		2022
Lease and Well	$	4.23	$	4.00
Transportation Costs	2.78		2.87
Gathering and Processing Costs	1.87		1.81
Depreciation, Depletion and Amortization (DD&A) -
Oil and Gas Properties	8.95		10.19
Other Property, Plant and Equipment	0.45		0.46
General and Administrative (G&A)	1.71		1.56
Interest Expense, Net	0.49		0.60
Total (1)	$	20.48	$	21.49

(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 interest expense, net for the three months ended March 31, 2023, compared to the same period of 2022, 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, produced 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 $359 million for the first quarter of 2023 increased $41 million from $318 million for the same prior year period primarily due to increased operating and maintenance costs ($25 million), increased lease and well administrative expenses ($9 million) and increased workover expenditures ($4 million), all in the United States. 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 $236 million for the first quarter of 2023 increased $8 million from $228 million for the same prior year period primarily due to increased transportation costs related to the Permian Basin ($18 million) and the Dorado gas play ($4 million), partially offset by decreased transportation costs related to the Eagle Ford play ($11 million) and the Rocky Mountain area ($3 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.

-27-

Gathering and processing costs increased $15 million to $159 million for the first quarter of 2023 compared to $144 million for the same prior year period primarily due to increased gathering and processing fees ($14 million) and increased operating and maintenance expenses ($9 million), both related to production from the Permian Basin; partially offset by decreased gathering and processing fees due to the sale of certain legacy natural gas assets in the Rocky Mountain area in the first quarter of 2022 ($9 million).

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 first quarter of 2023 decreased $49 million to $798 million from $847 million for the same prior year period. DD&A expenses associated with oil and gas properties for the first quarter of 2023 were $50 million lower than the same prior year period. The decrease primarily reflects decreased unit rates in the United States ($112 million), partially offset by increased production in the United States ($62 million). Unit rates in the United States decreased primarily due to upward reserve revisions related to favorable well performance, increased ethane recovery and reserve additions at lower costs per Boe during the quarter.

G&A expenses of $145 million for the first quarter of 2023 increased $21 million from $124 million for the same prior year period primarily due to increased employee-related costs ($9 million) and professional and other services ($4 million).

Exploration costs of $50 million for the first quarter of 2023 increased $5 million from $45 million for the same prior year period due primarily to increased geological and geophysical expenditures in the United States.

Interest expense, net of $42 million for the first quarter of 2023 decreased $6 million compared to the same prior year period primarily due to decreased interest expense on certain royalty payments.

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.

The following table represents impairments for the first quarter of 2023 and 2022 (in millions):

	Three Months Ended March 31,
	2023		2022
Proved properties	$	2	$	1
Unproved properties	32		54
Total	$	34	$	55

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.

-28-

Taxes other than income for the first quarter of 2023 decreased $61 million to $329 million (7.8% of wellhead revenues) from $390 million (7.4% of wellhead revenues) for the same prior year period. The decrease in taxes other than income was primarily due to decreased severance/production taxes in the United States.

Other income, net was $65 million for the first quarter of 2023 compared to other expense, net of $1 million for the same prior year period. The change of $66 million in the first quarter of 2023 was primarily due to increased interest income ($60 million) and decreased deferred compensation expense ($15 million), partially offset by the absence of equity income due to the sale of EOG's equity interest in ammonia plant investments in Trinidad in the first quarter of 2023 ($13 million).

EOG recognized an income tax provision of $572 million for the first quarter of 2023 compared to an income tax provision of $107 million for the first quarter of 2022, primarily due to increased pretax income.  The net effective tax rate for the first quarter of 2023 was unchanged from the prior year rate of 22%.

Capital Resources and Liquidity

Cash Flow. The primary sources of cash for EOG during the three months ended March 31, 2023, were funds generated from operations and proceeds from sales of assets. The primary uses of cash were exploration and development expenditures; funds used in operations; repayment of maturing debt; dividend payments to stockholders; purchases of treasury stock; and other property, plant and equipment expenditures. During the first three months of 2023, EOG's cash balance decreased $954 million to $5,018 million from $5,972 million at December 31, 2022.

Net cash provided by operating activities of $3,255 million for the first three months of 2023 increased $2,427 million compared to the same period of 2022 primarily due to net cash provided by a change in collateral posted for financial commodity derivative contracts ($2,599 million) and net cash provided by working capital and other assets and liabilities in the first three months of 2023 ($132 million) compared to net cash used in working capital and other assets and liabilities in the first three months of 2022 ($891 million), partially offset by a decrease in wellhead revenues ($1,097 million).

Net cash used in investing activities of $1,567 million for the first three months of 2023 increased $611 million compared to the same period of 2022 due to an increase in additions to oil and gas properties ($366 million), an increase in additions to other property, plant and equipment ($249 million) and a decrease in proceeds from the sale of assets ($29 million), partially offset by net cash used in working capital associated with investing activities in the first three months of 2023 ($35 million) compared to net cash used in working capital associated with investing activities in the first three months of 2022 ($68 million).

Net cash used in financing activities of $2,642 million for the first three months of 2023 included repayments of long-term debt ($1,250 million), cash dividend payments ($1,067 million), purchases of treasury stock ($317 million) and repayment of finance lease liabilities ($8 million). Net cash used in financing activities of $1,072 million for the first three months of 2022 included cash dividend payments ($1,023 million), purchases of treasury stock in connection with stock compensation plans ($43 million) and repayment of finance lease liabilities ($10 million).

-29-

Total Expenditures. For the year 2023, EOG's updated budget for exploration and development and other property, plant and equipment expenditures is estimated to range from approximately $5.8 billion to $6.2 billion, excluding acquisitions, non-cash transactions and exploration costs. The table below sets out components of total expenditures for the three-month periods ended March 31, 2023 and 2022 (in millions):

	Three Months Ended March 31,
	2023		2022
Expenditure Category
Capital
Exploration and Development Drilling	$	1,181	$	813
Facilities	96		109
Leasehold Acquisitions (1)	48		64
Property Acquisitions (2)	4		5
Capitalized Interest	8		8
Subtotal	1,337		999
Exploration Costs	50		45
Dry Hole Costs	1		3
Exploration and Development Expenditures	1,388		1,047
Asset Retirement Costs	10		27
Total Exploration and Development Expenditures	1,398		1,074
Other Property, Plant and Equipment (3)	319		70
Total Expenditures	$	1,717	$	1,144

(1)    Leasehold acquisitions included $31 million and $58 million for the three-month periods ended March 31, 2023 and 2022, respectively, related to non-cash property exchanges.

(2)    Property acquisitions included $2 million and $5 million for the three-month periods ended March 31, 2023 and 2022, respectively, related to non-cash property exchanges.

(3)    Other Property, Plant and Equipment included $133 million for the three month period ended March 31, 2023, related to the acquisition of a gathering and processing system in the Powder River Basin.

Exploration and development expenditures of $1,388 million for the first three months of 2023 were $341 million higher than the same period of 2022 primarily due to increased exploration and development drilling expenditures in the United States ($363 million), partially offset by decreased leasehold acquisitions ($16 million). Exploration and development expenditures for the first three months of 2023 of $1,388 million consisted of $1,254 million in development drilling and facilities, $122 million in exploration, $8 million in capitalized interest and $4 million in property acquisitions. Exploration and development expenditures for the first three months of 2022 of $1,047 million consisted of $907 million in development drilling and facilities, $127 million in exploration, $8 million in capitalized interest and $5 million in property acquisitions.

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.

Financial Commodity Derivative Transactions. As more fully discussed in Note 12 to the Consolidated Financial Statements included in EOG's 2022 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 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 Financial Commodity Derivative Contracts on the Condensed Consolidated Statements of Income and Comprehensive Income. 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 financial commodity derivative contracts, net of associated collateral posted, was reflected on the Condensed Consolidated Balance Sheets at March 31, 2023, as a net liability of $407 million.

As discussed in "Operating Revenues and Other," the net cash paid for settlements of financial commodity derivative contracts during the first three months of 2023 was $123 million.

Presented below is a comprehensive summary of EOG's financial commodity derivative contracts settled during the period from January 1, 2023 to April 28, 2023 (closed) and outstanding as of April 28, 2023. Crude oil 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).

Information Regarding Forward-Looking Statements

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," "ambition," "initiative," "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 financial or 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 drilling, completion and operating costs and capital expenditures, generate cash flows, pay down or refinance indebtedness, achieve, reach or otherwise meet initiatives, plans, goals, ambitions or targets with respect to emissions, other environmental matters, safety matters or other ESG (environmental/social/governance) matters, 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 such assumptions are accurate or will prove to have been correct or that any of such expectations will be achieved (in full or at all) or will be achieved on the expected or anticipated timelines. 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 (NGLs), 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 and operating costs and capital expenditures 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 success of EOG's cost-mitigation initiatives and actions in offsetting the impact of inflationary pressures on EOG's operating costs and capital expenditures;

•the extent to which EOG is successful in its efforts to market its production of crude oil and condensate, NGLs 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 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 climate change-related regulations, policies and initiatives (for example, with respect to air emissions); tax laws and regulations (including, but not limited to, carbon tax and emissions-related legislation); environmental, health and safety laws and regulations relating to 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, NGLs and natural gas; laws and regulations with respect to financial derivatives and hedging activities; and laws and regulations with respect to the import and export of crude oil, natural gas and related commodities;

-33-

•the impact of climate change-related policies and initiatives at the corporate and/or investor community levels and other potential developments related to climate change, such as (but not limited to) changes in consumer and industrial/commercial behavior, preferences and attitudes with respect to the generation and consumption of energy; increased availability of, and increased consumer and industrial/commercial demand for, competing energy sources (including alternative energy sources); technological advances with respect to the generation, transmission, storage and consumption of energy; alternative fuel requirements; energy conservation measures and emissions-related legislation; decreased demand for, and availability of, services and facilities related to the exploration for, and production of, crude oil, NGLs and natural gas; and negative perceptions of the oil and gas industry and, in turn, reputational risks associated with the exploration for, and production of, crude oil, NGLs and natural gas;

•continuing political and social concerns relating to climate change and the greater potential for shareholder activism, governmental inquiries and enforcement actions and litigation and the resulting expenses and potential disruption to EOG's day-to-day operations;

•the extent to which EOG is able to successfully and economically develop, implement and carry out its emissions and other ESG-related initiatives and achieve its related targets and initiatives;

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

•the extent to which EOG's third-party-operated crude oil and natural gas properties are operated successfully, economically and in compliance with applicable laws and regulations;

•competition in the oil and gas exploration and production industry for the acquisition of licenses, leases and properties;

•the availability and cost of, and competition in the oil and gas exploration and production industry for, employees, labor and other personnel, facilities, equipment, materials (such as water, sand, fuel and tubulars) and services;

•the accuracy of reserve estimates, which by their nature involve the exercise of professional judgment and may therefore be imprecise;

•weather, including its impact on crude oil and natural gas demand, and weather-related delays in drilling and in the installation and operation (by EOG or third parties) of production, gathering, processing, refining, compression, storage, transportation, and export facilities;

•the ability of EOG's customers and other contractual counterparties to satisfy their obligations to EOG and, related thereto, to access the credit and capital markets to obtain financing needed to satisfy their obligations to EOG;

•EOG's ability to access the commercial paper market and other credit and capital markets to obtain financing on terms it deems acceptable, if at all, and to otherwise satisfy its capital expenditure requirements;

•the extent to which EOG is successful in its completion of planned asset dispositions;

•the extent and effect of any hedging activities engaged in by EOG;

•the timing and extent of changes in foreign currency exchange rates, interest rates, inflation rates, global and domestic financial market conditions and global and domestic general economic conditions;

•the duration and economic and financial impact of epidemics, pandemics or other public health issues;

•geopolitical factors and political conditions and developments around the world (such as the imposition of tariffs or trade or other economic sanctions, political instability and armed conflict), including in the areas in which EOG operates;

•the extent to which EOG incurs uninsured losses and liabilities or losses and liabilities in excess of its insurance coverage;

•acts of war and terrorism and responses to these acts; and

•the other factors described under ITEM 1A, Risk Factors of EOG's Annual Report on Form 10-K for the year ended December 31, 2022, and any updates to those factors set forth in EOG's subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K.

-34-

In light of these risks, uncertainties and assumptions, the events anticipated by EOG's forward-looking statements may not occur, and, if any of such events do, we may not have anticipated the timing of their occurrence or the duration or extent of their impact on our actual results. Accordingly, you should not place any undue reliance on any of EOG's forward-looking statements. 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, Exchange Act) 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 such 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 March 31, 2023.

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 Value of Shares Purchased as Part of Publicly Announced Plans or Programs (2)		Approximate Dollar Value of Shares that May Yet Be Purchased Under the Plans or Programs (2)
January 1, 2023 - January 31, 2023	11,621	$	130.57	$	—	$	5,000,000,000
February 1, 2023 - February 28, 2023	32,989	114.40		—		$	5,000,000,000

Total	3,001,098	105.70		310,256,971

(1)Includes 2,941,836 shares repurchased during March 2023, at an average price of $105.46 per share (inclusive of commissions and transaction fees), pursuant to the November 2021 Authorization (as defined and further discussed below); such repurchases count against the November 2021 Authorization. Also includes 59,262 total shares that were withheld by or returned to EOG during the quarter ended March 31, 2023, at an average price of $117.38 per share, (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 (such shares do not count against the November 2021 Authorization).

(2)Effective November 4, 2021, EOG's Board of Directors (Board) established a new share repurchase authorization that allows for the repurchase by EOG of up to $5 billion of its common stock (November 2021 Authorization). As of the date of this filing, (i) EOG has repurchased an aggregate 2,941,836 shares at a total cost of $310,256,971 (inclusive of commissions and transaction fees) under the November 2021 Authorization and (ii) an additional $4,689,743,029 of shares may be purchased under the November 2021 Authorization.

Under the November 2021 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 is at the discretion of EOG's management and depends on a variety of factors, including the trading price of EOG's common stock, corporate and regulatory requirements, and other market and economic conditions. Repurchased shares are held as treasury shares and are available for general corporate purposes. The November 2021 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.

Accounting Policies [Abstract]

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, 2022, filed on February 23, 2023 (EOG's 2022 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 months ended March 31, 2023, are not necessarily indicative of the results to be expected for the full year.

Recently Issued Accounting Standards. In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (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 were entered into on or before December 31, 2022. In December 2022, the FASB issued ASU 2022-06, "Reference Rate Reform (Topic 848)" (ASU 2022-06), which deferred the sunset date of Topic 848 until December 31, 2024. EOG has evaluated the provisions of ASU 2020-04 and ASU 2022-06 and has concluded that their application will not have a material impact on EOG's 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 2022 Annual Report, EOG maintains various stock-based compensation plans. Stock-based compensation expense is included on the Condensed Consolidated Statements of Income and Comprehensive Income based upon the job function of the employees receiving the grants as follows (in millions):

	Three Months Ended March 31,
	2023		2022
Lease and Well	$	12	$	13
Gathering and Processing Costs	1		1
Exploration Costs	5		5
General and Administrative	16		16
Total	$	34	$	35

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 Amended and Restated EOG Resources, Inc. 2008 Omnibus Equity Compensation Plan (2008 Plan) from and after the April 29, 2021 effective date of the 2021 Plan. The 2021 Plan provides for grants of stock options, stock-settled stock appreciation rights (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 were 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).

At March 31, 2023, approximately 16 million common shares remained available for grant under the 2021 Plan. EOG's policy is to issue shares related to the 2021 Plan grants from previously authorized unissued shares or treasury shares to the extent treasury shares are available.

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 $6 million and $8 million during the three months ended March 31, 2023 and 2022, respectively.

EOG did not grant any stock options or SARs during the three-month period ended March 31, 2023. Weighted average fair values and valuation assumptions used to value stock options and SARs granted during the three-month period ended March 31, 2022 and ESPP grants during the three-month periods ended March 31, 2023 and 2022 are as follows:

	Stock Options/SARs			ESPP
	Three Months Ended March 31,			Three Months Ended March 31,
	2022			2023			2022
Weighted Average Fair Value of Grants	$	28.30		$	32.31		$	23.07
Expected Volatility	42.20		%	42.97		%	39.72		%
Risk-Free Interest Rate	0.89		%	4.66		%	0.22		%
Dividend Yield	3.28		%	2.47		%	3.32		%
Expected Life	5.3 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 three-month periods ended March 31, 2023 and 2022 (stock options and SARs in thousands):

	Three Months Ended March 31, 2023			Three Months Ended March 31, 2022
	Number of Stock Options/SARs	Weighted Average Exercise Price		Number of Stock Options/SARs	Weighted Average Exercise Price
Outstanding at January 1	4,225	$	77.49	9,969	$	84.37
Granted	—	—		2	97.64
Exercised (1)	(175)	77.08		(2,324)	84.63

Outstanding at March 31 (2)	4,019	$	77.49	7,566	$	84.28
Vested or Expected to Vest (3)	3,875	$	77.86	7,256	$	85.05
Exercisable at March 31 (4)	2,294	$	84.89	3,886	$	101.26

(1)The total intrinsic value of stock options/SARs exercised during the three months ended March 31, 2023 and 2022 was $8 million and $62 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 March 31, 2023 and 2022 was $155 million and $277 million, respectively. At March 31, 2023 and 2022, the weighted average remaining contractual life was 3.9 years and 4.3 years, respectively.

(3)The total intrinsic value of stock options/SARs vested or expected to vest at March 31, 2023 and 2022 was $149 million and $260 million, respectively. At March 31, 2023 and 2022, the weighted average remaining contractual life was 3.8 years and 4.3 years, respectively.

(4)The total intrinsic value of stock options/SARs exercisable at March 31, 2023 and 2022 was $74 million and $82 million, respectively. At both March 31, 2023 and 2022, the weighted average remaining contractual life was 2.9 years.

At March 31, 2023, unrecognized compensation expense related to non-vested stock option, SAR and ESPP grants totaled $28 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 1.1 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 $25 million for each of the three months ended March 31, 2023 and 2022.

The following table sets forth restricted stock and restricted stock unit transactions for the three-month periods ended March 31, 2023 and 2022 (shares and units in thousands):

	Three Months Ended March 31, 2023			Three Months Ended March 31, 2022
	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	4,113	$	80.77	4,680	$	69.37
Granted	36	122.34		14	110.66
Released (1)	(38)	55.23		(699)	93.37
Forfeited	(42)	84.23		(51)	66.77
Outstanding at March 31 (2)	4,069	$	81.33	3,944	$	65.30

(1)The total intrinsic value of restricted stock and restricted stock units released during the three months ended March 31, 2023 and 2022 was $4 million and $81 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 March 31, 2023 and 2022 was $466 million and $470 million, respectively.

At March 31, 2023, unrecognized compensation expense related to restricted stock and restricted stock units totaled $261 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 1.6 years.

Performance Units. EOG grants Performance Units annually to its executive officers without cost to them. For the grants made prior to September 2022, as more fully discussed in the grant agreements, the applicable performance metric is EOG's total shareholder return (TSR) over a three-year performance period relative to the TSR over the same period of a designated group of peer companies. Upon the application of the applicable performance multiple at the completion of the three-year performance period, a minimum of 0% and a maximum of 200% of the Performance Units granted could be outstanding.

For the grants made beginning in September 2022, as more fully discussed in the grant agreements, the applicable performance metrics are 1) EOG's TSR over a three-year performance period relative to the TSR over the same period of a designated group of peer companies and 2) EOG's average return on capital employed (ROCE) over the three-year performance period. At the end of the three-year performance period, a performance multiple based on EOG's relative TSR ranking will be determined, with a minimum performance multiple of 0% and a maximum performance multiple of 200%. A specified modifier ranging from -70% to +70% will then be applied to the performance multiple based on EOG's average ROCE over the three-year performance period, provided that in no event shall the performance multiple, after applying the ROCE modifier, be less than 0% or exceed 200%. Furthermore, if EOG's TSR over the three-year performance period is negative (i.e., less than 0%), the performance multiple will be capped at 100%, regardless of EOG's relative TSR ranking or three-year average ROCE.

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 $3 million and $2 million for the three months ended March 31, 2023 and 2022, respectively.

The following table sets forth the Performance Unit transactions for the three-month periods ended March 31, 2023 and 2022 (units in thousands):

	Three Months Ended March 31, 2023				Three Months Ended March 31, 2022
	Number of Units		Weighted Average Grant Date Fair Value		Number of Units	Weighted Average Grant Date Fair Value
Outstanding at January 1	688		$	83.82	679	$	84.97
Granted	—		—		—	—
Released (1)	(86)		79.98		(57)	136.74
Forfeited for Performance Multiple (2)	(86)		79.98		(56)	136.74
Outstanding at March 31 (3)	516	(4)	$	85.10	566	$	74.60

(1)The total intrinsic value of Performance Units released was $10 million and $7 million for the three months ended March 31, 2023 and 2022, respectively. The intrinsic value is based upon the closing price of EOG's common stock on the date the Performance Units are released.

(2)Upon completion of the Performance Period for the Performance Units granted in 2019 and 2018, a performance multiple of 50% was applied to each of the grants resulting in a forfeiture of Performance Units in both February 2023 and February 2022.

(3)The total intrinsic value of Performance Units outstanding at March 31, 2023 and 2022 was approximately $59 million and $67 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 1,031 Performance Units could be outstanding.

At March 31, 2023, 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 2.0 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 March 31, 2023 and December 31, 2022, and did not utilize any commercial paper borrowings during the three months ended March 31, 2023 and 2022.

On March 15, 2023, EOG repaid upon maturity the $1,250 million aggregate principal amount of its 2.625% Senior Notes due 2023.

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 March 31, 2023, EOG was in compliance with this financial covenant. At March 31, 2023 and December 31, 2022, 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 March 31, 2023, would have been 5.76% and 8.0%, respectively.

Common Stock. In November 2021, the Board established a new share repurchase authorization that allows for the repurchase by EOG of up to $5 billion of its common stock (November 2021 Authorization). Under the November 2021 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 is at the discretion of EOG's management and depends on a variety of factors, including the trading price of EOG's common stock, corporate and regulatory requirements, and other market and economic conditions. Repurchased shares are held as treasury shares and are available for general corporate purposes. The November 2021 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. During the three months ended March 31, 2023, EOG repurchased 2.9 million shares of common stock for approximately $310 million (inclusive of transaction fees and commissions) pursuant to the November 2021 Authorization. As of March 31, 2023, approximately $4.7 billion remained available for repurchases under the November 2021 Authorization.

On February 23, 2023, the Board declared a quarterly cash dividend on the common stock of $0.825 per share, paid on April 28, 2023, to stockholders of record as of April 14, 2023. The Board also declared on such date a special cash dividend on the common stock of $1.00 per share, paid on March 30, 2023, to stockholders of record as of March 16, 2023.

On May 4, 2023, the Board declared a quarterly cash dividend on the common stock of $0.825 per share to be paid on July 31, 2023, to stockholders of record as of July 17, 2023.

Fair Value Measurements

Fair Value Measurements

Recurring Fair Value Measurements. As more fully discussed in Note 13 to the Consolidated Financial Statements included in EOG's 2022 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 March 31, 2023 and December 31, 2022 (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

See Note 12 for the balance sheet amounts and classification of EOG's financial commodity derivative instruments at March 31, 2023 and December 31, 2022.

The estimated fair value of financial commodity derivative contracts was based upon forward commodity price curves based on quoted market prices. Financial 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 is 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, natural gas liquids (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 FASB's 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 financial 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 March 31, 2023 and December 31, 2022, respectively, EOG had outstanding $3,640 million and $4,890 million aggregate principal amount of senior notes, which had estimated fair values at such dates of approximately $3,592 million and $4,740 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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

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 2022 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.

Financial Commodity Derivative Contracts. Presented below is a comprehensive summary of EOG's financial commodity derivative contracts settled during the three-month period ended March 31, 2023 (closed) and outstanding as of March 31, 2023. Crude oil 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).

Financial Commodity Derivatives Location on Balance Sheet. The following table sets forth the amounts and classification of EOG's outstanding financial commodity derivative instruments at March 31, 2023 and December 31, 2022. Certain amounts may be presented on a net basis on the Condensed Consolidated Financial Statements when such amounts are with the same counterparty and subject to a master netting arrangement (in millions):

Current portion	Liabilities from Price Risk Management Activities (1)	$	31	$	169
Noncurrent portion	Other Liabilities (2)	376		371

(1)    The current portion of Liabilities from Price Risk Management Activities consists of gross liabilities of $63 million, partially offset by gross assets of $32 million and no collateral posted at March 31, 2023. The current portion of Liabilities from Price Risk Management Activities consists of gross liabilities of $287 million, partially offset by gross assets of $26 million and collateral posted with counterparties of $92 million, at December 31, 2022.

(2)    The noncurrent portion of Liabilities from Price Risk Management Activities consists of gross liabilities of $377 million, partially offset by gross assets of $1 million and no collateral posted at March 31, 2023. The noncurrent portion of Liabilities from Price Risk Management Activities consists of gross liabilities of $606 million, partially offset by gross assets of $3 million and collateral posted with counterparties of $232 million, at December 31, 2022.

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 both March 31, 2023 and December 31, 2022. EOG had no collateral posted and no collateral held at March 31, 2023. EOG had $324 million of collateral posted and no collateral held at December 31, 2022. EOG had no collateral posted and no collateral held at May 3, 2023.

In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (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 were entered into on or before December 31, 2022. In December 2022, the FASB issued ASU 2022-06, "Reference Rate Reform (Topic 848)" (ASU 2022-06), which deferred the sunset date of Topic 848 until December 31, 2024.
