Inventory (ASC 330): disclosure examples

Inventories, consisting of products available for sale, are primarily accounted for using the first-in first-out method, and are valued at the lower of cost and net realizable value. This valuation requires us to make judgments, based on currently available information, about the likely method of disposition, such as through sales to individual customers, returns to product vendors, or liquidations, and expected recoverable values of each disposition category. These assumptions about future disposition of inventory are inherently uncertain and changes in our estimates and assumptions may cause us to realize material write-downs in the future. As a measure of sensitivity, for every 1% of additional inventory valuation allowance as of December 31, 2025, we would have recorded an additional cost of sales of approximately $405 million.

In addition, we enter into supplier commitments for certain electronic device components and certain products. These commitments are based on forecasted customer demand. If we reduce these commitments, we may incur additional costs.

Income Taxes

We are subject to income taxes in the U.S. (federal and state) and numerous foreign jurisdictions. Tax laws, regulations, administrative practices, principles, and interpretations in various jurisdictions may be subject to significant change, with or without notice, due to economic, political, and other conditions, and significant judgment is required in evaluating and estimating our provision and accruals for these taxes. There are many transactions that occur during the ordinary course of business for which the ultimate tax determination is uncertain. In addition, our actual and forecasted earnings are subject to change due to economic, political, and other conditions and significant judgment is required in determining our ability to use our deferred tax assets.

Inventories. We measure inventory at the lower of cost or net realizable value considering judgments and estimates related to future customer demand and other market conditions, such as the impact of the macroeconomic environment and global trade policies. Although we believe these estimates are reasonable, any significant changes in customer demand that are less favorable than our previous estimates may require additional inventory write-downs and would be reflected in cost of sales resulting in a negative impact to our gross margin in that period. For fiscal 2025 and 2024, the net effect from changes in this estimate and related reserves was less than 1% of cost of revenues during each period.

Impairment of Goodwill, Other Indefinite-Lived Assets and Long-Lived Assets . We monitor our goodwill, other indefinite-lived assets and long-lived assets for the existence of impairment indicators and apply judgments in the valuation methods (generally income or market approach) and underlying inputs and assumptions utilized in such assessments, which are generally unobservable inputs. During fiscal 2025 and 2024, there were no material impairment charges for long-lived or indefinite-lived assets. Additionally, the estimated fair values of our QCT and QTL reporting units, based on our qualitative assessment, were substantially in excess of their respective carrying values at September 28, 2025.

Legal and Regulatory Proceedings. We are currently involved in certain legal and regulatory proceedings, the outcomes of which are inherently uncertain. If there is at least a reasonable possibility that a material loss may have been incurred associated with pending legal and regulatory proceedings, we disclose such fact. We record our best estimate of a loss related to pending legal and regulatory proceedings when the loss is considered probable and the amount can be reasonably estimated. We face difficulties in evaluating or estimating likely outcomes and/or the amount of possible loss in certain legal and regulatory proceedings. Until the final resolution of such matters, there may be an exposure to loss in excess of the amount recorded (or the possible loss disclosed), and such amounts could be material.

▪ Inventories: We use the last-in, first-out (“LIFO”) method to determine the cost of the majority of our inventories, with the remainder valued using the first-in, first-out (“FIFO”) and average cost methods. We state inventories under LIFO at the lower of cost or market, while we state inventories under FIFO and average cost at the lower of cost and net realizable value. It is a generally recognized industry practice to classify leaf tobacco inventories as a current asset although part of such inventories, because of the duration of the curing and aging process, ordinarily would not be used within one year. We determined the cost of approximately 76 % and 77 % of our inventories at December 31, 2025 and 2024, respectively, using the LIFO method. The recorded LIFO amounts of our inventories were approximately $ 0.7 billion lower than the current cost of our inventories at December 31, 2025 and 2024.

We record an inventory reserve for the estimated adjustment to mark down merchandise inventory to the lower of cost or net realizable value (LCNRV). This reserve is based on our current knowledge with respect to inventory levels, sales trends and historical experience. During fiscal 2025, our reserve increased approximately $7 million to $229 million as of January 30, 2026.

We also record an inventory reserve for the estimated shrinkage between physical inventories. This reserve is based primarily on actual shrink results from previous physical inventories. During fiscal 2025, the inventory shrink reserve increased approximately $9 million to $436 million as of January 30, 2026.

In addition, we receive funds from vendors in the normal course of business, principally as a result of purchase volumes, early payments, or sales-based promotions of vendors’ products. Generally, these vendor funds do not represent the reimbursement of specific, incremental, and identifiable costs that we incurred to sell the vendor’s product. The majority of the vendor funds associated with these purchases are earned under agreements that are negotiated on an annual basis or shorter. The funds are recorded as a reduction to the cost of inventory as they are earned. As the related inventory is sold, the amounts are recorded as a reduction to cost of sales. Funds that are determined to be reimbursements of specific, incremental, and identifiable costs incurred to sell vendors’ products are recorded as an offset to the related expense.

Judgments and uncertainties involved in the estimate

We do not believe that our merchandise inventories are subject to significant risk of markdown in the near term in excess of our established reserves, and we have the ability to adjust purchasing practices based on anticipated sales trends and general economic conditions. However, changes in consumer purchasing patterns or a deterioration in product quality could result in the need for additional reserves. Likewise, changes in the estimated shrink reserve may be necessary, based on the timing and results of physical inventories. We also apply judgment in the determination of obsolete inventory and assumptions about net realizable value.

Inventories: Depending on the business, U.S. inventories are stated at the lower of cost or market using the last-in, first-out (LIFO) method or the lower of cost and net realizable value (NRV) using the first-in, first-out (FIFO) method. Non-U.S. inventories are stated at the lower of cost and NRV using the FIFO method. At December 31, 2025 and 2024, approximatel y 62 % and 59 %, respectively, of all inventory utilized the LIFO method.

Property, Plant and Equipment: Property, plant and equipment are stated at cost, less accumulated depreciation. Assets placed in service are recorded at cost and depreciated using the straight-line method over the estimated useful life of the asset except for leasehold improvements, which are depreciated over the shorter of their economic useful life or their lease term. The range of useful lives used to depreciate property, plant and equipment is as follows:

Buildings	10	to	50	years
Machinery and equipment	2	to	12	years
Software	2	to	7	years

Major expenditures for replacements and significant improvements that increase asset values and extend useful lives are also capitalized. Capitalized costs are amortized over their estimated useful lives using the straight-line method. Repairs and maintenance expenditures that do not extend the useful life of the asset are charged to expense as incurred. The carrying amounts of assets that are sold or retired and the related accumulated depreciation are removed from the accounts in the year of disposal, and any resulting gain or loss is reflected within current earnings.

The Company assesses the recoverability of the carrying value of its property, plant and equipment whenever events or changes in circumstances indicate that the carrying amount of the asset group may not be recoverable. Recoverability is measured by a comparison of the carrying amount of the asset group to the future net undiscounted cash flows expected to be generated by the asset group. If the undiscounted cash flows are less than the carrying amount of the asset group, an impairment loss is recognized for the amount by which the carrying value of the asset group exceeds the fair value of the asset group.

Inventories are stated at the lower of cost and net realizable value. The majority of inventory is valued based on standard costs, which are revised at the beginning of each year and approximate average costs, while the remainder is principally valued on a first-in, first-out basis. Following are the components of inventory as of September 30:

2024	2025
Finished products	512	520
Raw materials and work in process	1,668	1,693
Total inventories	2,180	2,213

Fair Value Measurement

ASC 820, Fair Value Measurement , establishes a formal hierarchy and framework for measuring certain financial statement items at fair value, and requires disclosures about fair value measurements and the reliability of valuation inputs. Under ASC 820, measurement assumes the transaction to sell an asset or transfer a liability occurs in the principal or at least the most advantageous market for that asset or liability. Within the hierarchy, Level 1 instruments use observable market prices for an identical item in active markets and have the most reliable valuations. Level 2 instruments are valued through broker/dealer quotation or other approaches using market-observable inputs for similar items in active markets, including forward and spot prices, interest rates and volatilities. Level 3 instruments are valued using inputs not observable in an active market, such as company-developed future cash flow estimates, and are considered the least reliable. Valuations for all of the Company's financial instruments fall within Level 2. The fair value of the Company's long-term debt is Level 2, estimated using current interest rates and pricing from financial institutions and other market sources for debt with similar maturities and characteristics.

Property, Plant and Equipment

The Company records investments in land, buildings, and machinery and equipment at cost. Depreciation is computed principally using the straight-line method over estimated service lives, which for principal assets are 30 to 40 years for buildings and 8 to 12 years for machinery and equipment. Long-lived tangible assets are reviewed for impairment whenever events or changes in business circumstances indicate the carrying value of the assets may not be recoverable. Impairment losses are recognized based on estimated fair values if the sum of estimated future undiscounted cash flows of the related assets is less than the carrying values.

The components of property, plant and equipment as of September 30 follow:

Inventories. Inventories consist primarily of tubular goods, materials for completion operations, well equipment and gathering lines held for use in the exploration for, and development and production of, crude oil, NGLs and natural gas reserves. EOG accounts for inventories at the lower of cost and net realizable value with adjustments made, as appropriate, to recognize any reductions in value.

Revenue Recognition. EOG presents disaggregated revenues by type of commodity within its Consolidated Statements of Income and Comprehensive Income and by geographic areas defined as operating segments. See Note 11.

Revenues are recognized for the sale of crude oil and condensate, NGLs and natural gas at the point control of the product is transferred to the customer, typically when production is delivered and title or risk of loss transfers to the customer. Arrangements for such sales are evidenced by signed contracts with prices typically based on stated market indices, with certain adjustments for product quality and geographic location. As EOG transfers control of the product shortly after production and after performance obligations have been fulfilled, contract assets and contract liabilities are not recognized. The balances of accounts receivable from contracts with customers as of December 31, 2025 and 2024, were $ 2,289 million and $ 2,184 million, respectively, and are included in Accounts Receivable, Net on the Consolidated Balance Sheets. Losses incurred on receivables from contracts with customers are infrequent and have been immaterial. Certain arrangements provide for the sale of fixed quantities of commodities in future years with pricing mechanisms based on future market prices of the commodity at time of delivery. EOG does not disclose the value of these obligations given the uncertainty of the future realized transaction price.

Crude Oil and Condensate. EOG sells its crude oil and condensate production at the wellhead or further downstream at a contractually-specified delivery point. Revenue is recognized when control transfers to the customer based on contract terms which reflect prevailing market prices. Any costs incurred prior to the transfer of control, such as gathering and transportation, are recognized as Gathering, Processing and Transportation Costs.

F-12

Inventory costs primarily consist of product cost from the Company's suppliers, as well as inbound freight, import duties, taxes, insurance, logistics and other handling fees. Inventories, substantially all of which are finished goods, are stated at lower of cost and net realizable value and valued on either an average or a specific identification cost basis. In some instances, the Company ships products directly from its suppliers to the customer, with the related inventory and cost of sales recognized on a specific identification basis.

If the net realizable value of inventory is estimated to be less than the cost of the inventory, a reserve is recorded equal to the difference between the cost of the inventory and the estimated net realizable value. This reserve is recorded as a charge to Cost of sales. As of May 31, 2026, the Company's inventory reserve was $ 213 million compared to $ 233 million as of May 31, 2025.

PROPERTY, PLANT AND EQUIPMENT AND DEPRECIATION

Property, plant and equipment are recorded at cost. Depreciation is determined on a straight-line basis for land improvements, buildings and leasehold improvements over 2 to 40 years and for machinery and equipment over 2 to 15 years.

Depreciation of assets used in warehousing and product distribution is recorded in Cost of sales. Depreciation of all other assets is recorded in Operating overhead expense.

SOFTWARE DEVELOPMENT COSTS

Expenditures for major software purchases and software developed for internal use are capitalized and amortized over 2 to 12 years on a straight-line basis, once ready for their intended use. The Company's policy provides for the capitalization of external direct costs associated with developing or obtaining internal use computer software. The Company also capitalizes certain payroll and payroll-related costs for employees who are directly associated with internal use computer software projects. The amount of capitalizable payroll costs with respect to these employees is limited to the time directly spent on such projects. Costs associated with preliminary project stage activities, training, maintenance and all other post-implementation stage activities are expensed as incurred.

IMPAIRMENT OF LONG-LIVED ASSETS

Fuel. As part of our strategy to mitigate the cost of the refining margin reflected in the price of jet fuel, our wholly owned subsidiary, Monroe Energy, LLC ("Monroe"), operates the Trainer oil refinery. Refined products (finished goods) and feedstock and blendstock inventories (work-in-process) are carried at the lower of cost and net realizable value. We use jet fuel in our airline operations that is produced by the refinery, purchased directly from third parties and procured through the exchanges with third parties of gasoline, diesel and other refined products ("non-jet fuel products") the refinery produces. Cost is determined using the first-in, first-out method. Costs include the raw material consumed plus direct manufacturing costs (such as labor, utilities and supplies) as incurred and an applicable portion of manufacturing overhead.

Expendables Parts and Supplies. Inventories of expendable parts related to flight equipment, which cannot be economically repaired, reconditioned or reused after removal from the aircraft, are carried at moving average cost and charged to aircraft maintenance materials and outside repairs as consumed. An allowance for obsolescence is provided over the remaining useful life of the related fleet. We also provide allowances for parts identified as excess or obsolete to reduce the carrying costs to the lower of cost or net realizable value. These parts are estimated to have residual value of 5 % of the original cost.

Accounting for Refinery Related Buy/Sell Agreements

To the extent that we receive jet fuel for non-jet fuel products exchanged under buy/sell agreements, we account for these transactions as nonmonetary exchanges. We have recorded these nonmonetary exchanges at the carrying amount of the non-jet fuel products transferred within aircraft fuel and related taxes on our Consolidated Statements of Operations ("income statement").

Derivatives

Changes in fuel prices, interest rates and foreign currency exchange rates impact our results of operations. In an effort to manage our exposure to these risks, we may enter into derivative contracts and adjust our derivative portfolio as market conditions change. Our derivative contracts are recognized at fair value on our balance sheets and had net balances of $ 1 million and $ 17 million at December 31, 2025 and 2024, respectively. See Note 3, "Fair Value Measurements," for further information regarding our derivative contracts.

Inventories are stated at the lower of cost and net realizable value, with cost determined in a manner that approximates weighted average cost. The Company periodically analyzes its inventory levels, and writes down inventory that has become obsolete, inventory that has a cost basis in excess of its estimated realizable value and inventory in excess of expected sales requirements as cost of product sales. The determination of whether inventory costs will be realizable requires estimates of future prices by management. If actual market conditions are less favorable than projected by management, additional write-downs of inventory may be required, which would be recorded in the consolidated statements of operations.

Investments

The Company’s investments consist of convertible note instruments, public equity securities with readily determinable fair values, private equity securities without readily determinable fair values, and equity-method investments. The classification of an investment is determined based on the nature of the investment, the Company’s ability and intent to hold the investment, and the degree to which the Company may exercise influence over the investee.

• Convertible note instruments are recorded using the fair value option method of accounting. Accordingly, convertible note instruments are remeasured at fair value on a recurring basis, with any changes in the fair value option recorded in other (expense) income, net.

• Public equity securities with readily determinable fair values are recorded at fair value. Subsequent changes in fair value are recorded in other (expense) income, net. Derivative financial instruments to purchase public equity securities are recorded at fair value. The estimated fair value of derivative financial instruments is determined based on the Black-Scholes valuation model. Changes in fair value of derivative instruments are recorded in other (expense) income, net.

• Private equity securities without readily determinable fair values and where the Company does not have significant influence are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Adjustments to private equity securities are recorded in other (expense) income, net.

Inventories – Inventories are valued at the lower of cost and net realizable value. Cost is determined using the first-in, first-out method. The Company writes down its inventory for estimated obsolescence or excess inventory equal to the difference between the cost of inventory and the estimated net realizable value based upon assumptions about future demand and market conditions.

Product Warranties – The Company sells certain of its products to customers with a product warranty that allows customers to return a defective product during a specified warranty period following the purchase in exchange for a replacement product, repair at no cost to the customer, or the issuance of a credit to the customer. The Company accrues its estimated exposure to warranty claims based upon current and historical product sales data, warranty costs incurred, and any other related information known to the Company.

Property, Plant and Equipment and Depreciation and Amortization – Property, plant and equipment is stated at cost less accumulated depreciation and amortization. Depreciation and amortization are provided for using principally the straight-line method over the estimated useful lives of the assets as follows:

We value our inventory, which includes raw materials, assembly and test, and other manufacturing costs, at the lower of cost and net realizable value. Cost is computed using standard cost, which approximates actual cost, on a first-in, first-out basis. Net realizable value is the estimated selling price of our products in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. We regularly review inventory quantities on hand and non-cancellable purchase commitments and record write-downs for excess and obsolete inventory based primarily on the shipment

history and our estimated forecast of product demand. These factors are impacted by market and economic conditions, technology changes, new product introductions and changes in strategic direction. If the future demand for our products is less favorable than our forecasts, the value of the inventories may be required to be reduced, which could result in additional expense to us and affect our results of operations. We do not believe there is a reasonable likelihood that there will be a material change in the future estimates or assumptions that we use to calculate our inventory reserve. However, if estimates regarding customer demand are inaccurate or changes in technology affect demand for certain products in an unforeseen manner, we may be exposed to losses or gains that could be material.
