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 of America (United States) with proved reserves in the United States and the Republic of Trinidad and Tobago (Trinidad). EOG is focused on being among the highest return and lowest cost producers, committed to strong environmental performance and playing a significant role in the long-term future of energy. EOG operates under a consistent business and operational strategy that focuses on a comprehensive approach to developing acreage through industry cycles. EOG evaluates rate of return, net present value, margins, payback period and other key metrics. This strategy is intended to enhance the generation of cash flow and earnings from each unit of production on a cost-efficient basis, allowing EOG to maximize long-term growth in shareholder value and maintain a strong balance sheet. EOG implements its strategy primarily by emphasizing the drilling of internally generated prospects in order to find and develop low-cost reserves. Maintaining the lowest possible operating cost structure, coupled with efficient and safe operations and robust environmental stewardship practices and performance, is integral in the implementation of EOG's strategy.

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 (e.g., the ongoing conflict in the Middle East and the related disruption of maritime transportation routes for these commodities), the global supply of, and demand for, crude oil and condensate, NGLs and natural gas, the availability of other energy supplies and other factors, including tariffs, trade policies and agreements and trade barriers or other restrictions imposed by the U.S. government or other governments and the related impact of such measures on commodity and financial markets. Compared to its expectations at the beginning of 2026, EOG realized higher crude oil and condensate prices in the first half of 2026 and anticipates realizing higher crude oil and condensate prices for the full-year 2026, in each case as a result of the ongoing conflict in the Middle East.

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 six months of 2026, the average U.S. New York Mercantile Exchange (NYMEX) crude oil and natural gas prices were $82.57 per barrel and $3.92 per million British thermal units (MMBtu), respectively, representing increases of 22% and 10%, respectively, from the average NYMEX prices for the same period in 2025. 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.

Including the impact of EOG's NGL financial derivative contracts and based on EOG's tax position, EOG's price sensitivity as of June 30, 2026, for each $1.00 per barrel increase or decrease in crude oil and condensate price, combined with the estimated change in NGL price, is approximately $172 million for net income and $221 million for pretax cash flows from operating activities, in each case for the full-year 2026.

Including the impact of EOG's natural gas financial derivative contracts and based on EOG's tax position and the portion of EOG's anticipated natural gas volumes for which prices have not (as of June 30, 2026) been determined under long-term marketing contracts, EOG's price sensitivity as of June 30, 2026, for each $0.10 per thousand cubic feet increase or decrease in natural gas price, is approximately $60 million for net income and $77 million for pretax cash flows from operating activities, in each case for the full-year 2026.

Operating Efficiencies. EOG has undertaken (and continues to undertake) initiatives to increase its drilling, completion and operating efficiencies and improve the performance of its wells. Such initiatives 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 have resulted in increased footage completed per day and pumping hours per day; (iii) drilling extended laterals, which has resulted in a decrease in cost per foot drilled; and (iv) EOG's self-sourced sand program, which has provided supply certainty and resulted in operational efficiencies in its well completion operations. In addition, EOG has entered 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 be successful and sufficient to offset the impacts of any future inflationary pressures (such as from tariffs, other trade barriers, the ongoing conflict in the Middle East, or other macroeconomic factors) on EOG's operating costs and capital expenditures, cash flows and results of operations. Further, there can be no assurance that any such pressures or factors will not impact EOG's ability to conduct its future day-to-day drilling, completion and production operations.

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 six months of 2026, EOG continued to focus on initiatives to increase its drilling, completion and operating efficiencies and improve well performance. 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 66% and 70% of EOG's United States production during the first six months of 2026 and 2025, respectively. During the first six months of 2026, EOG's drilling and completion activities occurred primarily in the Delaware Basin, the Utica and the Eagle Ford play. EOG's major producing areas in the United States are in New Mexico, Texas and Ohio.

Trinidad. In Trinidad, EOG continues to produce natural gas which is sold to the National Gas Company of Trinidad and Tobago Limited under existing supply contracts. Crude oil and condensate are sold to both Heritage Petroleum Company Limited and BP Trinidad and Tobago LLC.

During the first six months of 2026, EOG completed its drilling program in the Mento Field located in the Ska, Mento and Reggae Area and continued construction of the Coconut offshore platform.

Other International. As discussed in EOG's Annual Report on Form 10-K for the year ended December 31, 2025, filed on February 24, 2026 (EOG's 2025 Annual Report), EOG entered into exploration programs in both the Kingdom of Bah

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 5 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 (the choice of this threshold does not imply that matters with potential monetary sanctions in excess of $1 million are necessarily material to EOG's business or financial condition). Applying this threshold, there are no environmental proceedings to disclose for the quarter ended June 30, 2026.

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:

(1)Includes 9,576,509 shares repurchased during the quarter ended June 30, 2026, at an average price of $135.13 per share (inclusive of commissions and transaction fees), pursuant to the Share Repurchase Authorization (as defined and further discussed below); such repurchases count against the Share Repurchase Authorization. The share repurchases effected during the period April 1, 2026 through May 6, 2026 were made pursuant to a Rule 10b5-1 trading plan entered into by EOG on March 31, 2026. Also includes 33,549 total shares that were withheld by or returned to EOG during the quarter ended June 30, 2026, at an average price of $138.08 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 Share Repurchase Authorization.

(2)In November 2021, EOG's Board of Directors (Board) established a new share repurchase authorization allowing for the repurchase by EOG of up to $5 billion of its common stock and, in November 2024, increased such share repurchase authorization from $5 billion to $10 billion. Effective May 20, 2026, the Board again increased such share repurchase authorization, from $10 billion to $20 billion (Share Repurchase Authorization). As of June 30, 2026 (i) EOG had repurchased an aggregate 68,951,725 shares at a total cost of $8,348,823,887 (inclusive of commissions and transaction fees) under the Share Repurchase Authorization and (ii) an additional $11,651,176,113 of shares remained available for repurchases under the Share Repurchase Authorization.

(3)Under the Share Repurchase 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, other market and economic conditions, the availability of cash to effect repurchases and EOG's anticipated future capital expenditures and other commitments requiring cash. Repurchased shares are held as treasury shares and are available for general corporate purposes. The Share Repurchase Authorization has no time limit, does not require EOG to repurchase a specific number of shares and may be modified, suspended or terminated by the Board at any time.

Trading Plans/Arrangements. On June 25, 2026, Jeffrey R. Leitzell, EOG's Executive Vice President and Chief Operating Officer, terminated his written Rule 10b5-1 trading arrangement, dated June 26, 2025, in respect of EOG's common stock. The description of such trading arrangement set forth in Part II, Item 5 of EOG's Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2025 is incorporated herein by reference.

On June 26, 2026, Mr. Leitzell adopted a new written Rule 10b5-1 trading arrangement in respect of EOG's common stock that is intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) promulgated under the Securities Exchange Act of 1934 (as amended). The arrangement, which was adopted in accordance with EOG's Insider Trading Policy and at a time when Mr. Leitzell was not in possession of material, non-public information regarding EOG, provides for the sale by Mr. Leitzell of:

(1)up to 17,739 shares currently held by Mr. Leitzell;

(2)100% of the net shares to be received by Mr. Leitzell upon the vesting of previous grants of an aggregate 8,787 shares of restricted stock; and

(3)25% of the net shares to be received by Mr. Leitzell upon the vesting of previous grants of an aggregate 13,182 restricted stock units with performance-based conditions (performance units);

in each case, during the specific time periods and subject to the limit price (i.e., trigger price) conditions set forth in the arrangement (and subject to EOG's withholding of shares in satisfaction of the tax withholding obligations arising upon each such vesting). Mr. Leitzell's Rule 10b5-1 trading arrangement will commence following the applicable cooling-off period and will terminate upon the earlier of (i) the completion of all sales specified in the trading arrangement and (ii) June 30, 2028.

During the quarter ended June 30, 2026, no other Section 16 officer of EOG, and no director of EOG, adopted or terminated any Rule 10b5-1 trading arrangement or non-Rule 10b5-1 trading arrangement (in each case, as defined in Item 408(a) of Regulation S-K).
