(B) Crude oil and condensate volumes are from UAE and Bahrain operations. Natural gas volumes are from Bahrain operations; natural gas realized price represents contract price less partner's processing and distribution costs.

(C) Dollars per barrel or per thousand cubic feet, as applicable. Excludes the impact of financial commodity and other derivative instruments (see Note 9 to the Condensed Consolidated Financial Statements in EOG's Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2026).

(D) Thousand barrels of oil equivalent per day or million barrels of oil equivalent, as applicable; includes crude oil and condensate, NGLs and natural gas. Crude oil equivalent volumes are determined using a ratio of 1.0 barrel of crude oil and condensate or NGLs to 6.0 thousand cubic feet of natural gas. MMBoe is calculated by multiplying the MBoed amount by the number of days in the period and then dividing that amount by one thousand. 11

(A) Effective January 1, 2026, EOG combined Price Risk Management Activities into the Other line item. This presentation has been conformed for all periods presented and had no impact on previously reported Total Assets and Total Liabilities and Stockholders’ Equity.

(B) See Note 5 to the Condensed Consolidated Financial Statements in EOG’s Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2026. 12

To supplement the presentation of its financial results prepared in accordance with generally accepted accounting principles in the United States of America (GAAP), EOG’s quarterly earnings releases and related conference calls, accompanying earnings presentation slides and presentation slides for investor conferences contain certain financial measures that are not prepared or presented in accordance with GAAP. These non-GAAP financial measures may include, but are not limited to, Adjusted Net Income (Loss), Adjusted Cash Flow from Operations, Free Cash Flow, Net Debt and related statistics.

A reconciliation of each of these measures to their most directly comparable GAAP financial measure and related discussion is included in the tables on the following pages and can also be found in the “Reconciliations & Guidance” section of the “Investors” page of the EOG website at www.eogresources.com.

As further discussed in the tables on the following pages, EOG believes these measures may be useful to investors who follow the practice of some industry analysts who make certain adjustments to GAAP measures (for example, to exclude non-recurring items) to facilitate comparisons to others in EOG’s industry, and who utilize non-GAAP measures in their calculations of certain statistics (for example, return on capital employed and return on equity) used to evaluate EOG’s performance.

EOG believes that the non-GAAP measures presented, when viewed in combination with its financial results prepared in accordance with GAAP, provide a more complete understanding of the factors and trends affecting the company’s performance. As is discussed in the tables on the following pages, EOG uses these non-GAAP measures for purposes of (i) comparing EOG’s financial performance with the financial performance of other companies in the industry and (ii) analyzing EOG’s financial performance across periods.

The non-GAAP measures presented should not be considered in isolation, and should not be considered as a substitute for, or as an alternative to, EOG’s reported Net Income (Loss), Long-Term Debt (including Current Portion of Long- Term Debt), Net Cash Provided by Operating Activities and other financial results calculated in accordance with GAAP. The non-GAAP measures presented should be read in conjunction with EOG's consolidated financial statements prepared in accordance with GAAP.

In addition, because not all companies use identical calculations, EOG’s presentation of non-GAAP measures may not be comparable to, and may be calculated differently from, similarly titled measures disclosed by other companies, including its peer companies. EOG may also change the calculation of one or more of its non-GAAP measures from time to time – for example, to account for changes in its business and operations or to more closely conform to peer company or industry analysts’ practices.

The calculation of EOG's direct after-tax rate of return (ATROR) is based on EOG’s net estimated recoverable reserves for a particular well(s) or play, the estimated net present value of the future net cash flows from such reserves (for which EOG utilizes certain assumptions regarding future commodity prices and operating costs) and EOG's direct net costs incurred in drilling or acquiring such well(s). As such, EOG's direct ATROR for a particular well(s) or play cannot be calculated from EOG’s consolidated financial statements. 14

For the three months ended December 31, 2025, such amount was $21 million.

(2) Impairments primarily associated with the write-down to fair value of natural gas and crude oil assets in the Barnett Shale and Woodford Oil Window (mainly driven by play-specific economics and resource allocation).

(1) Includes gathering, processing and marketing revenue, other revenue, exploration costs, dry hole costs, impairments, marketing costs, taxes other than income, other income (expense), interest expense, the impact of changes in the effective income tax rate and the impact of share repurchases on diluted shares. 20

(1) Effective January 1, 2024, EOG combined Transportation Costs and Gathering and Processing Costs into one line item titled Gathering, Processing and Transportation Costs. This presentation has been conformed for all periods presented and had no impact on previously reported Net Income.

(2) EOG believes excluding the above-referenced items from General and Administrative Costs is appropriate and provides useful information to investors, as EOG views such items as non-recurring.

(3) EOG believes excluding the above-referenced items from Taxes Other Than Income is appropriate and provides useful information to investors, as EOG views such items as non-recurring.

(4) EOG believes excluding the above-referenced items from Interest Expense, Net is appropriate and provides useful information to investors, as EOG views such items as non-recurring.

(5) In general, EOG excludes impairments which are (i) attributable to declines in commodity prices, (ii) related to sales of certain oil and gas properties or (iii) the result of certain other events or decisions (e.g., a periodic review of EOG's oil and gas properties or other assets). EOG believes excluding these impairments from total exploration costs is appropriate and provides useful information to investors, as such impairments were caused by factors outside of EOG’s control (versus, for example, impairments that are due to EOG’s proved oil and gas properties not being as productive as it originally estimated). 27

1) 2025 volumes are from Bahrain operations; natural gas realized price represents contract price less partner’s processing and distribution costs.

2) EOG bases United States, Trinidad and Other International crude oil and condensate price differentials upon the West Texas Intermediate crude oil price at Cushing, Oklahoma, using the simple average of the daily settlement prices for the prompt-month NYMEX futures contract for each of the applicable calendar months.

3) EOG bases United States natural gas price differentials upon the natural gas price at Henry Hub, Louisiana, using the NYMEX Last Day Settle price for each of the applicable months.

4) The full-year 2022 realized natural gas price for Trinidad includes a one- time pricing adjustment of $0.76/Mcf for prior-period production following a contract amendment with the National Gas Company of Trinidad and Tobago Limited.

5) Capital Expenditures include expenditures for Exploration and Development Drilling, Facilities, Leasehold Acquisitions, Capitalized Interest, Dry Hole Costs and Other Property, Plant and Equipment. Capital Expenditures exclude Property Acquisitions, Asset Retirement Costs, Non-Cash Exchanges and Transactions and exploration costs incurred as operating expenses.

6) Effective January 1, 2024, EOG combined Transportation Costs and Gathering and Processing Costs into one line item titled Gathering, Processing and Transportation Costs. This presentation has been conformed for all periods presented and had no impact on previously reported Net Income.

7) Cash Operating Costs consist of LOE, GP&T and G&A. G&A (Non-GAAP) for fiscal year 2025 excludes costs related to the Encino acquisition, as reflected in the accompanying reconciliation schedules (see “Revenues, Costs and Margins Per Barrel of Oil Equivalent”). In addition, TOTI (% of revenues from sales of crude oil and condensate, NGLs and natural gas) (Non-GAAP) and G&A (Non-GAAP) for fiscal year 2024 and fiscal year 2022 exclude a state severance tax refund and related consulting fees, respectively, as reflected in the accompanying reconciliation schedules (see “Revenues, Costs and Margins Per Barrel of Oil Equivalent”). The per-Boe impact of such acquisition-related costs and consulting fees on G&A and total Cash Operating Costs for fiscal year 2025, 2024 and 2022 was $(0.19), $(0.02) and $(0.05), respectively.

8) In general, EOG excludes impairments which are (i) attributable to declines in commodity prices, (ii) related to sales of certain oil and gas properties or (iii) the result of certain other events or decisions (e.g., a periodic review of EOG’s oil and gas properties or other assets). EOG believes excluding these impairments from total impairment costs is appropriate and provides useful information to investors, as such impairments were caused by factors outside of EOG’s control (versus, for example, impairments that are due to EOG’s proved oil and gas properties not being as productive as it originally estimated). Impairments (Non-GAAP) for FY 2025 are adjusted from Impairments (GAAP) for FY 2025 by excluding $657 million of impairments, primarily associated with the write-down to fair value of natural gas and crude oil assets in the Barnett Shale and Woodford Oil Window (mainly driven by play-specific economics and resource allocation). Impairments (Non-GAAP) for FY 2024 are adjusted from Impairments (GAAP) for FY 2024 by excluding $291 million of impairments, primarily associated with the write-down to fair value of natural gas and crude oil assets in the Rocky Mountain area.

9) Net Interest for fiscal year 2025 excludes financing commitment costs related to the Encino acquisition, as reflected in the accompanying reconciliation schedules (see “Revenues, Costs and Margins Per Barrel of Oil Equivalent”). The per-Boe impact of such cost for fiscal year 2025 is $(0.01). 29

(A) Thousand barrels per day or million cubic feet per day, as applicable.

(B) Crude oil and condensate volumes are from UAE and Bahrain operations.
Natural gas volumes are from Bahrain operations; natural gas realized price
represents contract price less partner's processing and distribution costs.

(C) Dollars per barrel or per thousand cubic feet, as applicable. Excludes the
impact of financial commodity and other derivative instruments (see Note 9 to
the Condensed Consolidated Financial Statements in EOG's Quarterly Report on
Form 10-Q for the quarterly period ended September 30, 2026).

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

  Non-GAAP Financial Measures  
                               
To supplement the presentation of its financial results prepared in accordance
with generally accepted accounting principles in the United States of America
(GAAP), EOG’s quarterly earnings releases and related conference calls,
accompanying earnings presentation slides and presentation slides for investor
conferences contain certain financial measures that are not prepared or
presented in accordance with GAAP. These non-GAAP financial measures may
include, but are not limited to, Adjusted Net Income (Loss), Adjusted Cash Flow
from Operations, Free Cash Flow, Net Debt and related statistics.

A reconciliation of each of these measures to their most directly comparable
GAAP financial measure and related discussion is included in the tables on the
following pages and can also be found in the “Reconciliations & Guidance”
section of the “Investors” page of the EOG website at www.eogresources.com.

As further discussed in the tables on the following pages, EOG believes these
measures may be useful to investors who follow the practice of some industry
analysts who make certain adjustments to GAAP measures (for example, to exclude
non-recurring items) to facilitate comparisons to others in EOG’s industry, and
who utilize non-GAAP measures in their calculations of certain statistics (for
example, return on capital employed and return on equity) used to evaluate EOG’s
performance.

EOG believes that the non-GAAP measures presented, when viewed in combination
with its financial results prepared in accordance with GAAP, provide a more
complete understanding of the factors and trends affecting the company’s
performance. As is discussed in the tables on the following pages, EOG uses
these non-GAAP measures for purposes of (i) comparing EOG’s financial
performance with the financial performance of other companies in the industry
and (ii) analyzing EOG’s financial performance across periods.

The non-GAAP measures presented should not be considered in isolation, and
should not be considered as a substitute for, or as an alternative to, EOG’s
reported Net Income (Loss), Long-Term Debt (including Current Portion of Long-
Term Debt), Net Cash Provided by Operating Activities and other financial
results calculated in accordance with GAAP. The non-GAAP measures presented
should be read in conjunction with EOG's consolidated financial statements
prepared in accordance with GAAP.

In addition, because not all companies use identical calculations, EOG’s
presentation of non-GAAP measures may not be comparable to, and may be
calculated differently from, similarly titled measures disclosed by other
companies, including its peer companies. EOG may also change the calculation of
one or more of its non-GAAP measures from time to time – for example, to account
for changes in its business and operations or to more closely conform to peer
company or industry analysts’ practices.

Direct ATROR

The calculation of EOG's direct after-tax rate of return (ATROR) is based on
EOG’s net estimated recoverable reserves for a particular well(s) or play, the
estimated net present value of the future net cash flows from such reserves (for
which EOG utilizes certain assumptions regarding future commodity prices and
operating costs) and EOG's direct net costs incurred in drilling or acquiring
such well(s). As such, EOG's direct ATROR for a particular well(s) or play
cannot be calculated from EOG’s consolidated financial statements.

(Non-GAAP), EOG subtracts from reported Net Income (GAAP) the total net cash
paid for settlements of financial commodity derivative contracts during such
period. For the three months ended March 31, 2026, such amount was $53 million.

(1) Consistent with its customary practice, in calculating Adjusted Net Income
(Non-GAAP), EOG subtracts from reported Net Income (GAAP) the total net cash
paid for settlements of financial commodity derivative contracts during such
period. For the twelve months ended December 31, 2025, such amount was $56
million.

(2) Impairments primarily associated with the write-down to fair value of
natural gas and crude oil assets in the Barnett Shale and Woodford Oil Window
(mainly driven by play-specific economics and resource allocation).

(3) Consists of Encino acquisition-related G&A costs ($88 million) and financing
commitment costs ($6 million).

(1) Effective January 1, 2024, EOG combined Transportation Costs and Gathering
and Processing Costs into one line item titled Gathering, Processing and
Transportation Costs. This presentation has been conformed for all periods
presented and had no impact on previously reported Net Income.

(2) EOG believes excluding the above-referenced items from General and
Administrative Costs is appropriate and provides useful information to
investors, as EOG views such items as non-recurring.

(3) EOG believes excluding the above-referenced items from Taxes Other Than
Income is appropriate and provides useful information to investors, as EOG views
such items as non-recurring.

(4) EOG believes excluding the above-referenced items from Interest Expense, Net
is appropriate and provides useful information to investors, as EOG views such
items as non-recurring.

(5) In general, EOG excludes impairments which are (i) attributable to declines
in commodity prices, (ii) related to sales of certain oil and gas properties or
(iii) the result of certain other events or decisions (e.g., a periodic review
of EOG's oil and gas properties or other assets). EOG believes excluding these
impairments from total exploration costs is appropriate and provides useful
information to investors, as such impairments were caused by factors outside of
EOG’s control (versus, for example, impairments that are due to EOG’s proved oil
and gas properties not being as productive as it originally estimated).

1) 2025 volumes are from Bahrain operations; natural gas realized price
represents contract price less partner’s processing and distribution costs.

2) EOG bases United States, Trinidad and Other International crude oil and
condensate price differentials upon the West Texas Intermediate crude oil price
at Cushing, Oklahoma, using the simple average of the daily settlement prices
for the prompt-month NYMEX futures contract for each of the applicable calendar
months.

3) EOG bases United States natural gas price differentials upon the natural gas
price at Henry Hub, Louisiana, using the NYMEX Last Day Settle price for each of
the applicable months.

4) The full-year 2022 realized natural gas price for Trinidad includes a one-
time pricing adjustment of $0.76/Mcf for prior-period production following a
contract amendment with the National Gas Company of Trinidad and Tobago Limited.

5) Capital Expenditures include expenditures for Exploration and Development
Drilling, Facilities, Leasehold Acquisitions, Capitalized Interest, Dry Hole
Costs and Other Property, Plant and Equipment. Capital Expenditures exclude
Property Acquisitions, Asset Retirement Costs, Non-Cash Exchanges and
Transactions and exploration costs incurred as operating expenses.

6) Effective January 1, 2024, EOG combined Transportation Costs and Gathering
and Processing Costs into one line item titled Gathering, Processing and
Transportation Costs. This presentation has been conformed for all periods
presented and had no impact on previously reported Net Income.

7) Cash Operating Costs consist of LOE, GP&T and G&A. G&A (Non-GAAP) for fiscal
year 2025 excludes costs related to the Encino acquisition, as reflected in the
accompanying reconciliation schedules (see “Revenues, Costs and Margins Per
Barrel of Oil Equivalent”). In addition, TOTI (% of revenues from sales of crude
oil and condensate, NGLs and natural gas) (Non-GAAP) and G&A (Non-GAAP) for
fiscal year 2024 and fiscal year 2022 exclude a state severance tax refund and
related consulting fees, respectively, as reflected in the accompanying
reconciliation schedules (see “Revenues, Costs and Margins Per Barrel of Oil
Equivalent”). The per-Boe impact of such acquisition-related costs and
consulting fees on G&A and total Cash Operating Costs for fiscal year 2025, 2024
and 2022 was $(0.19), $(0.02) and $(0.05), respectively.

8) In general, EOG excludes impairments which are (i) attributable to declines
in commodity prices, (ii) related to sales of certain oil and gas properties or
(iii) the result of certain other events or decisions (e.g., a periodic review
of EOG’s oil and gas properties or other assets). EOG believes excluding these
impairments from total impairment costs is appropriate and provides useful
information to investors, as such impairments were caused by factors outside of
EOG’s control (versus, for example, impairments that are due to EOG’s proved oil
and gas properties not being as productive as it originally estimated).
Impairments (Non-GAAP) for FY 2025 are adjusted from Impairments (GAAP) for FY
2025 by excluding $657 million of impairments, primarily associated with the
write-down to fair value of natural gas and crude oil assets in the Barnett
Shale and Woodford Oil Window (mainly driven by play-specific economics and
resource allocation). Impairments (Non-GAAP) for FY 2024 are adjusted from
Impairments (GAAP) for FY 2024 by excluding $291 million of impairments,
primarily associated with the write-down to fair value of natural gas and crude
oil assets in the Rocky Mountain area.

9) Net Interest for fiscal year 2025 excludes financing commitment costs related
to the Encino acquisition, as reflected in the accompanying reconciliation
schedules (see “Revenues, Costs and Margins Per Barrel of Oil Equivalent”). The
per-Boe impact of such cost for fiscal year 2025 is $(0.01).
