Financial Statement Presentation

The consolidated financial statements of Eastman Chemical Company ("Eastman" or the "Company") and subsidiaries are prepared in conformity with accounting principles generally accepted ("GAAP") in the United States and of necessity include some amounts that are based upon management estimates and judgments. Future actual results could differ from such current estimates and judgments. The consolidated financial statements include assets, liabilities, sales revenue, and expenses of all majority-owned subsidiaries and joint ventures in which a controlling interest is maintained. Eastman accounts for other joint ventures and investments in minority-owned companies where it exercises significant influence on the equity basis. Intercompany transactions and balances are eliminated in consolidation. Certain prior period data has been reclassified in the consolidated financial statements and accompanying footnotes to conform to current period presentation.

Recently Adopted Accounting Standards

Accounting Standards Update ("ASU") 2023-05 Business Combination - Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement: On January 1, 2025, Eastman adopted this update, which requires that a joint venture must initially measure all contributions received upon its formation at fair value, largely consistent with Topic 805, Business Combinations. The guidance is intended to reduce diversity in practice and provide users of joint venture financial statements with more decision-useful information. This ASU is applied prospectively for all newly formed joint venture entities with a formation date on or after January 1, 2025. The adoption did not have a material impact on the Company's financial statements and related disclosures.

ASU 2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures: On January 1, 2025, Eastman adopted this update on a prospective basis, which modifies annual income tax disclosure requirements. The updated guidance mandates entities to provide more detailed information including specific categories in the income tax rate reconciliation, and the breakdown of income or loss from continuing operations before income tax expense or benefit, for both domestic and foreign. Additionally, entities must disclose income tax expense or benefit from continuing operations, categorized by federal, state, and foreign taxes. The guidance further requires disclosure of income tax payments to various jurisdictions. The adoption did not have a material impact on the financial statements. See Note 8, "Income Taxes" for related disclosures.

Accounting Standards Issued But Not Adopted as of December 31, 2025

ASU 2024-03 Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses: The Financial Accounting Standards Board ("FASB") issued this update in November 2024, which requires public companies to provide additional disclosure of certain income statement expense line items. This guidance is intended to improve transparency around the nature of expenses and their impact on financial performance. The ASU is effective for fiscal periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027. Early adoption is permitted. Management is currently evaluating the impact of the changes required by the new standard on the Company's financial statements and related disclosures.

ASU 2025-05 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets: The FASB issued this update in July 2025 to address the application of Topic 326 to current accounts receivable and current contract assets arising from transactions accounted for under Topic 606, Revenue from Contracts with Customers. The amendments provide a practical expedient permitting entities, when estimating expected credit losses for those balances, to assume that current conditions at the balance sheet date do not change over the remaining life of the asset. The ASU is effective for fiscal periods beginning after December 15, 2025, including interim periods within those years, with early adoption permitted. The Company expects to elect the practical expedient upon adoption. Management does not expect the changes under the new standard will have a material impact on the Company's financial statements and related disclosures.

ASU 2025-06 Intangibles Goodwill and Other Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software: The FASB issued this update in September 2025, which removes prescriptive development stages and establishes a probable-to-complete recognition threshold under which capitalization of software development costs begins when management has authorized and committed to funding the project and it is probable the project will be completed and used as intended. The ASU is effective for fiscal periods beginning after December 15, 2027, including interim periods within those years, with early adoption permitted. Management is currently evaluating the impact of the changes under the new standard on the Company's financial statements and related disclosures.
ASU 2025-10 Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities: The FASB issued this update in December 2025, which establishes authoritative guidance on the accounting for government grants, including grants related to an asset and grants related to income. The amendments, largely aligned with International Accounting Standards 20, IAS 20, Accounting for Government Grants and Disclosure of Government Assistance ("IAS 20"), require that a government grant not be recognized until it is probable the Company will comply with the conditions attached to the grant and that the grant will be received. The amendments further codify specific recognition approaches for asset-related grants and for income-related grants, with presentation as income or deducted from the related expense. The ASU is effective for fiscal periods beginning after December 15, 2028, including interim periods within those years, with early adoption permitted. Management is currently evaluating the impact of the changes under the new standard on the Company's financial statements and related disclosures.

Revenue Recognition

Eastman recognizes revenue when performance obligations of the sale are satisfied. Eastman sells to customers through master sales agreements or standalone purchase orders. The majority of the Company's terms of sale have a single performance obligation to transfer products. Accordingly, the Company recognizes revenue when control has been transferred to the customer, generally at the time of shipment of products.

Eastman accounts for shipping and handling as activities to fulfill the promise to transfer the good and does not allocate revenue to those activities. All related shipping and handling costs are recognized at the time of shipment. Amounts collected for sales or other similar taxes are presented net of the related tax expense rather than presenting them as additional revenue. The incremental cost of obtaining a sales contract is recognized as a selling expense when incurred given the potential amortization period for such an asset is one year or less. The possible existence of a significant financing component within a sales contract is ignored when the time between cash collection and performance is less than one year. Finally, the Company does not disclose any unfulfilled obligations as customer purchase order commitments have an original expected duration of one year or less and no consideration from customers is excluded from the transaction price.

The timing of Eastman's customer billings does not always match the timing of revenue recognition. When the Company is entitled to bill a customer in advance of the recognition of revenue, a contract liability is recognized. When the Company is not entitled to bill a customer until a period after the related recognition of revenue, a contract asset is recognized. Contract assets represent the Company's right to consideration for the exchange of goods under a contract but which are not yet billable to a customer for consignment inventory or pursuant to certain shipping terms. Contract liabilities were $4 million and $15 million as of December 31, 2025 and 2024, respectively, and are included as a part of "Payables and other current liabilities" and "Other long-term liabilities" in the Consolidated Statements of Financial Position. Contract assets were $66 million and $92 million as of December 31, 2025 and 2024, respectively, and are included as a component of "Miscellaneous receivables" in the Consolidated Statements of Financial Position.

For additional information, see Note 20, "Segment and Regional Sales Information".

Pension and Other Postretirement Benefits

Eastman maintains defined benefit pension and other postretirement benefits plans that provide eligible employees with retirement benefits. The estimated amounts of the costs and obligations related to these benefits reflect the Company's assumptions related to discount rates, expected return on plan assets, rate of compensation increase or decrease for employees, and health care cost trends. The estimated cost of providing plan benefits also depends on demographic assumptions including retirements, mortality, turnover, and plan participation.

Eastman's pension and other postretirement benefit plans costs consist of two elements: 1) ongoing costs recognized quarterly, which are comprised of service and interest costs, expected returns on plan assets, and amortization of prior service credits; and 2) mark-to-market ("MTM") gains and losses recognized annually, in the fourth quarter of each year, primarily resulting from changes in actuarial assumptions for discount rates and the differences between actual and expected returns on plan assets. Any interim remeasurements triggered by a curtailment, settlement, or significant plan changes are recognized in the quarter in which such remeasurement event occurs.

For additional information, see Note 11, "Retirement Plans".
Environmental Costs

Eastman recognizes environmental remediation costs when it is probable that the Company has incurred a liability at a contaminated site and the amount can be reasonably estimated. When a single amount cannot be reasonably estimated but the cost can be estimated within a range, the Company recognizes the minimum undiscounted amount. This undiscounted amount reflects liabilities expected to be paid within approximately 30 years and the Company's assumptions about remediation requirements at the contaminated site, the nature of the remedy, the outcome of discussions with regulatory agencies and other potentially responsible parties at multi-party sites, and the number and financial viability of other potentially responsible parties. Changes in the estimates on which the accruals are based, unanticipated government enforcement action, or changes in health, safety, environmental, and chemical control regulations and testing requirements could result in higher or lower costs.

The Company also establishes reserves for closure and post-closure costs associated with the environmental and other assets it maintains. Environmental assets include but are not limited to waste management units, such as landfills, water treatment facilities, and surface impoundments. When these types of assets are constructed or installed, a loss contingency reserve is established for the anticipated future costs associated with the retirement or closure of the asset based on its expected life and the applicable regulatory closure requirements. The Company recognizes the asset retirement obligations in the period in which they are incurred if a reasonable estimate of fair value can be made. The asset retirement obligations are discounted to expected present value and subsequently adjusted for changes in fair value. These future estimated costs are charged to earnings over the estimated useful life of the assets. If the Company changes its estimate of the environmental asset retirement obligation costs or its estimate of the useful lives of these assets, earnings will be impacted in the period the estimate is changed. The associated estimated asset retirement costs are capitalized as part of the carrying value of the long-lived assets and depreciated over their useful life and charged to "Cost of sales" in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings.

Environmental costs are capitalized if they extend the life of the related property, increase its capacity, or mitigate the possibility of future contamination. The cost of operating and maintaining environmental control facilities is charged to "Cost of sales" in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings, as incurred.

For additional information see Note 13, "Environmental Matters and Asset Retirement Obligations".

Share-Based Compensation

Eastman recognizes compensation expense in "Selling, general and administrative expense" in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings for stock options and other share-based compensation awards based upon the grant-date fair value over the substantive vesting period. 

For additional information, see Note 18, "Share-Based Compensation Plans and Awards".

Restructuring of Operations

Eastman records restructuring charges for costs incurred in connection with consolidation of operations, exited business or product lines, or shutdowns of specific sites that are expected to be substantially completed within twelve months. These restructuring charges are recorded as incurred, and are associated with site closures, legal and environmental matters, demolition, contract terminations, or other costs and charges directly related to the restructuring. The Company records severance charges for employee separations when the separation is probable and reasonably estimable. In the event employees are required to perform future service, the Company records severance charges ratably over the remaining service period of those employees.

For additional information, see Note 16, "Asset Impairments, Restructuring, and Other Charges, Net".
Income Taxes

The provision for income taxes has been determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax bases of Eastman's assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. The recoverability of the Company's deferred tax assets are evaluated each quarter by assessing the likelihood of future profitability and available tax planning strategies that could be implemented to realize the Company's net deferred tax assets. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Provision has been made for income taxes on unremitted earnings of subsidiaries and affiliates, except for subsidiaries in which earnings are deemed to be indefinitely reinvested. The calculation of income tax liabilities involves uncertainties in the application of complex tax laws and regulations, which are subject to legal interpretation and management judgment. Eastman's income tax returns are regularly examined by federal, state and foreign tax authorities, and those audits may result in proposed adjustments. The Company has evaluated these potential issues under the more-likely-than-not standard of the accounting literature. A tax position is recognized if it meets this standard and is measured at the largest amount of benefit that has a greater than 50 percent likelihood of being realized. Such judgments and estimates may change based on audit settlements, court cases and interpretation of tax laws and regulations. The Company accrues interest related to unrecognized income tax positions, which is included as a component of the income tax provision on the balance sheet. The accrued interest related to unrecognized income tax positions and taxes resulting from the global intangible low-tax income are recorded as a component of the income tax provision.

For additional information, see Note 8, "Income Taxes".

Cash and Cash Equivalents

Cash and cash equivalents include cash, time deposits, and readily marketable securities with original maturities of three months or less.

Fair Value Measurements

Eastman records recurring and non-recurring financial assets and liabilities as well as all non-financial assets and liabilities subject to fair value measurement at the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. These fair value principles prioritize valuation inputs across three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company's assumptions used to measure assets and liabilities at fair value. An asset or liability's classification within the various levels is determined based on the lowest level input that is significant to the fair value measurement.

Accounts Receivable and Allowance for Credit Losses

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Eastman maintains allowances for estimated credit losses, which are developed at a market, country, and region level based on risk of collection as well as current and forecasted economic conditions. The Company calculates the allowance based on an assessment of the risk when the accounts receivable is recognized. Write-offs are recorded at the time a customer receivable is deemed uncollectible. Allowance for credit losses were $14 million and $15 million as of December 31, 2025 and 2024, respectively. The Company does not enter into receivables of a long-term nature, also known as financing receivables, in the normal course of business.
Inventories

Inventories measured by the last-in, first-out ("LIFO") method are valued at the lower of cost or market and inventories measured by the first-in, first-out ("FIFO") method are valued at the lower of cost or net realizable value. Eastman determines the cost of most raw materials, work in process, and finished goods inventories in the United States and Switzerland by the LIFO method. The cost of all other inventories is determined by the average cost method, which approximates the FIFO method. The Company writes-down its inventories equal to the difference between the carrying value of inventory and the estimated market value or net realizable value based upon assumptions about future demand and market conditions.

For additional information, see Note 3, "Inventories".

Properties

Eastman records properties at cost. Maintenance and repairs are charged to earnings; replacements and betterments are capitalized. When Eastman retires or otherwise disposes of assets, it removes the cost of such assets and related accumulated depreciation from the accounts. The Company records any profit or loss on retirement or other disposition in "Cost of sales" in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings. Asset impairments are reflected as increases in accumulated depreciation for properties that have been placed in service. In instances when an asset has not been placed in service and is impaired, the associated costs are removed from the appropriate property accounts.

For additional information, see Note 4, "Properties and Accumulated Depreciation" and Note 16, "Asset Impairments, Restructuring, and Other Charges, Net".
Depreciation and Amortization

Depreciation expense is calculated based on historical cost and the estimated useful lives of the assets, generally using the straight-line method. Estimated useful lives for buildings and building equipment generally range from 20 to 50 years. Estimated useful lives generally ranging from 3 to 33 years are applied to machinery and equipment in the following categories: computer software (3 to 5 years); office furniture and fixtures and computer equipment (5 to 10 years); vehicles, railcars, and general machinery and equipment (5 to 20 years); and manufacturing-related improvements (20 to 33 years). Accelerated depreciation is reported when the estimated useful life is shortened and continues to be reported in "Cost of sales" in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings.

For additional information, see Note 4, "Properties and Accumulated Depreciation".

Amortization expense for definite-lived intangible assets is generally determined using a straight-line method over the estimated useful life of the asset. Amortization expense is reported in "Cost of sales" in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings.

For additional information, see Note 5, "Goodwill and Other Intangible Assets".

Impairment of Long-Lived Assets

Definite-lived Assets

Properties and equipment and definite-lived intangible assets to be held and used by Eastman are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The review of properties and equipment and the review of definite-lived intangible assets is performed at the asset group level, which is the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. If the carrying amount is not considered to be recoverable, an analysis of fair value is triggered. An impairment is recognized for the excess of the carrying amount of the asset over the estimated fair value.
Goodwill

Goodwill is an asset determined as the residual of the purchase price over the fair value of identified assets and liabilities
acquired in a business combination. Eastman conducts testing of goodwill for impairment annually in the fourth quarter or more frequently when events and circumstances indicate an impairment may have occurred. The testing of goodwill is performed at the "reporting unit" level which the Company has determined to be its "components". Components are defined as an operating segment or one level below an operating segment, and in order to be a reporting unit, the component must (1) be a "business" as defined by applicable accounting standards (an integrated set of activities and assets that is capable of being conducted and managed for the purpose of providing a return in the form of dividends, lower costs, or other economic benefits directly to the investors or other owners, members, or participants); (2) have discrete financial information available; and (3) be reviewed regularly by Company operating segment management. The Company aggregates certain components into reporting units based on economic similarities. An impairment is recognized when the reporting unit's estimated fair value is less than its carrying value. The Company may use a qualitative analysis or a quantitative analysis in testing the carrying value of goodwill of each reporting unit for impairment. When the quantitative analysis is used, the Company uses an income approach, specifically a discounted cash flow model.

Indefinite-lived Intangible Assets

Eastman conducts testing of indefinite-lived intangible assets annually in the fourth quarter or more frequently when events and circumstances indicate an impairment may have occurred. The carrying value of an indefinite-lived intangible asset is considered to be impaired when the fair value, estimated by appraisal or based on discounted future cash flows of certain related products, is less than the respective carrying value.

Indefinite-lived intangible assets, consisting primarily of various tradenames, are tested for potential impairment by comparing the estimated fair value to the carrying amount. The Company may use a qualitative analysis or a quantitative analysis in testing the carrying value of indefinite-lived intangible assets for impairment. When the quantitative analysis is used, the Company uses an income approach, specifically the relief from royalty method. The estimated fair value of tradenames is determined based on an assumed royalty rate savings, discounted by the calculated market participant estimated weighted average cost of capital ("WACC") plus a risk premium.

For additional information, see Note 5, "Goodwill and Other Intangible Assets".

Leases

There are two types of leases: financing and operating. Both types of leases have associated right-to-use assets and lease liabilities that are valued at the net present value of the lease payments and recognized on the Consolidated Statements of Financial Position. The discount rate used in the measurement of a right-to-use asset and lease liability is the rate implicit in the lease whenever that rate is readily determinable. If the rate implicit in the lease is not readily determinable, the collateralized incremental borrowing rate is used. The Company elected the accounting policy not to apply the recognition and measurement requirements to short-term leases with a term of 12 months or less and do not include a bargain purchase option. Residual guarantee payments that become probable and estimable are recognized as rent expense over the remaining life of the applicable lease.

For lease accounting policies, see Note 12, "Leases and Other Commitments".

Investments

The consolidated financial statements include the accounts of Eastman and all its subsidiaries and entities or joint ventures in which a controlling interest is maintained. The Company includes its share of earnings and losses of such investments in "Net earnings attributable to Eastman" and "Comprehensive income attributable to Eastman" located in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings and in "Total equity" located in the Consolidated Statements of Financial Position.

Investments in affiliates over which the Company has significant influence but not a controlling interest are accounted for under the equity method of accounting. These investments are included in "Other noncurrent assets" in the Consolidated Statements of Financial Position. The Company includes its share of earnings and losses of such investments in "Other (income) charges, net" located in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings.
For additional information, see Note 6, "Equity Investments".

Derivative and Non-Derivative Financial Instruments

Eastman uses derivative and non-derivative instruments to manage its exposure to market risks, such as changes in foreign currency exchange rates, commodity prices, and interest rates. The Company does not enter into derivative transactions for speculative purposes.

The Company's derivative instruments are recognized as either assets or liabilities on the Consolidated Statements of Financial Position and measured at fair value. Hedge accounting will be discontinued prospectively for all hedges that no longer qualify for hedge accounting treatment.

For additional information, see Note 10, "Derivative and Non-Derivative Financial Instruments".

Litigation and Contingent Liabilities

From time to time, Eastman and its operations are parties to or targets of lawsuits, claims, investigations and proceedings, including product liability, personal injury, asbestos, patent and intellectual property, commercial, contract, environmental, antitrust, health and safety, and employment matters, which are handled and defended in the ordinary course of business. The Company accrues a contingent loss liability for such matters when it is probable that a liability has been incurred and the amount can be reasonably estimated. When a single amount cannot be reasonably estimated but the cost can be estimated within a range, the Company accrues the minimum amount. The Company expenses legal costs, including those expected to be incurred in connection with a loss contingency, as incurred.

For additional information, see Note 14, "Legal Matters".

Working Capital Management and Off-Balance Sheet Arrangements

The Company engages in off-balance sheet, uncommitted accounts receivable factoring programs as a routine part of its ordinary business operations. Through these programs, entire invoices may be sold to third-party financial institutions, the vast majority of which are without recourse. Under these agreements, the Company sells the invoices at face value, less a transaction fee, which substantially equals the carrying value and fair value with no gain or loss recognized, and no credit loss exposure is retained. Available capacity under these programs, which the Company uses as a routine source of working capital funding, is dependent on the level of accounts receivable eligible to be sold and the financial institutions' willingness to purchase such receivables. In addition, certain programs also require that the Company continue to service, administer, and collect the sold accounts receivable at market rates. The total amount of receivables sold in 2025 and 2024 were $2.7 billion and $2.7 billion, respectively.

The Company works with suppliers to optimize payment terms and conditions on accounts payable to enhance the timing of working capital and cash flows. As part of its supplier financing programs, suppliers may voluntarily sell receivables due from Eastman to a participating financial institution. Eastman's responsibility is limited to making payments on the terms originally negotiated with suppliers, and the range of payment terms Eastman negotiates with suppliers is consistent regardless of whether a supplier participates in the program. Either Eastman or a participating financial institution may terminate a supplier finance program upon 90 days' notice. Within these programs, the Company maintains a structured payables program that utilizes a payables processing arrangement with a financial institution to support the processing and settlement of freight and logistics invoices, whereby the financial institution remits payments to certain freight service providers based on invoices approved by the Company, and the Company reimburses the financial institution. There are no fees for participation in these programs; however, the Company pays fixed per‑transaction fees for the invoice processing and payment services for the structured payables program.

Confirmed obligations in these programs of $110 million and $56 million at December 31, 2025 and 2024, respectively, are included in "Payables and other current liabilities" on the Consolidated Statements of Financial Position. The following table presents a rollforward of obligations confirmed as valid through these programs for the year ended December 31, 2025:

Government Grants

In the absence of explicit GAAP guidance on contributions received from government agencies, the Company applied by analogy the recognition and measurement guidance under IAS 20. The Company recognizes grants once it is probable that both of the following conditions will be met: (1) the Company is eligible to receive the grant, and (2) the Company is able to comply with the relevant conditions of the grant. Government grants whose primary condition is the purchase, construction, or acquisition of a long-lived asset are considered asset-based grants and are recognized as a reduction to such asset's cost basis, which reduces future depreciation expense. Proceeds received from asset-based grants are presented as cash inflows from investing activities on the Consolidated Statements of Cash Flows.

In 2024, the Company entered into a Cooperative Agreement ("the DOE grant") with the United States Department of Energy's ("DOE") Office of Clean Energy Demonstrations ("OCED") whereby certain costs incurred by the Company are reimbursed by the DOE. During the year ended December 31, 2024, pursuant to the DOE grant, the Company requested $11 million in reimbursements from the DOE, of which $9 million was received by the Company during 2024. The funds received reduced the carrying amount of certain fixed assets associated with the Company's Polyethylene Terephthalate Recycling Decarbonization Project in Longview, Texas (the "Project"), which were included in properties and equipment at December 31, 2024. The reduced carrying amount of the impacted assets is recognized in profit or loss over the life of the depreciable assets through reduced depreciation expense.

On May 29, 2025, the DOE terminated an award related to the Project. The Company continues to record reimbursements for amounts incurred prior to the date of the award termination and for which the Company is contractually entitled to under an assistance agreement with the DOE. The Company requested $21 million in reimbursements related to activity prior to the date of the award termination and has received $21 million in reimbursements from the DOE during the year. While waiting for a decision on reinstatement of the award, the Company is actively evaluating the impact of the termination on the project’s scope, timeline, and carrying values of associated assets. The Company has prepared a settlement proposal in the event reinstatement is not obtained.

Texas City Divestiture

On December 1, 2023, the Company completed the sale of its Texas City operations, which was reported in the Chemical Intermediates ("CI") segment ("Texas City Operations"). The sale excluded the plasticizer operations. The Company provided certain transition and post-closing services on agreed terms that were completed in 2024. The business was not reported as a discontinued operation because the sale did not have a major effect on the Company's operations and financial results.

The total consideration, after post-closing adjustments, was $498 million. The divestiture resulted in a $323 million gain.
The major classes of divested assets and liabilities as of the date of the divestiture were as follows:

At December 31, 2025, foreign net operating loss carryforwards totaled $2.5 billion. Of this amount, $800 million will expire in 1 to 20 years and $1.7 billion of the carryforwards have no expiration date. A valuation allowance of approximately $524 million has been provided against foreign net operating loss carryforwards and other foreign deferred income tax balances.

At December 31, 2025, there were no federal net operating loss carryforwards available to offset future taxable income. At December 31, 2025, foreign tax credit carryforwards of approximately $136 million were available to reduce possible future U.S. income taxes, which expire from 2029 to 2036. A partial valuation allowance of $135 million has been established for foreign tax credit carryforwards as of December 31, 2025.

At December 31, 2025, a partial valuation allowance of $47 million has been provided against state tax credits that the Company may not be able to utilize. A partial valuation allowance of $23 million has been established for the Solutia, Inc. ("Solutia") state net operating loss carryforwards.

Valuation allowances will be retained until there is sufficient positive evidence to conclude that it is more likely than not that the deferred tax assets will be realized, or the related statute expires.
All foreign earnings, with the exception of short-term liquid assets on certain foreign subsidiaries, including basis differences, continue to be considered indefinitely reinvested. The Company has not determined the deferred tax liability associated with these unremitted earnings and basis differences, as such determination is not practicable.

(1)The carrying value of the euro-denominated 1.875% notes due November 2026 fluctuates with changes in the euro to U.S. dollar exchange rate. The carrying value of these euro-denominated borrowings have been designated as non-derivative net investment hedges of a portion of the Company's net investments in euro functional-currency denominated subsidiaries to offset foreign currency fluctuations.
(2)Net proceeds from the bond issuance have been used to finance or refinance existing and future eligible green investment initiatives which contribute to Eastman's environmental sustainability strategy (a green bond).

In 2025, the Company issued an additional $250 million aggregate principal amount of the 5.0% notes due August 2029 in a registered public offering (the "2029 Notes"), which was originally issued in August 2024, resulting in an aggregate principal amount of $750 million. The net proceeds from the 2025 issuance were $246 million. In 2025, the Company also repaid the $450 million 3.80% notes due March 2025. There were no debt extinguishment costs associated with the repayment of this debt. All proceeds from the issued notes and the redemption of the 3.80% notes are reported under financing activities on the Consolidated Statements of Cash Flows.

Credit Facility, Term Loans, and Commercial Paper Borrowings

The Company has access to a $1.50 billion revolving credit agreement (the "Credit Facility"), in which borrowings under the Credit Facility are subject to interest at varying spreads above quoted market rates and a commitment fee is paid on the total unused commitment. The Credit Facility provides available liquidity for general corporate purposes and supports commercial paper borrowings. Commercial paper borrowings are classified as short-term. In December 2025, the Credit Facility was amended to remove the sustainability-linked pricing terms from the agreement. In February 2026, the Credit Facility was amended to extend the maturity to February 2031 and to temporarily adjust the maximum leverage ratio covenant through the fiscal quarter ending June 30, 2027 in the event of further macroeconomic uncertainty impacting operating results. All other material terms of the Credit Facility remain unchanged. At December 31, 2025 and 2024, the Company had no outstanding borrowings under the Credit Facility and no commercial paper borrowings.

In 2025, the Company repaid $100 million of the remaining $250 million five-year term loan (the "2027 Term Loan"). There were no extinguishment costs associated with the partial repayment of the 2027 Term Loan. The outstanding balance on the 2027 Term Loan was $150 million at December 31, 2025 and $250 million at December 31, 2024, with variable interest rates of 5.14% and 5.58%, respectively. The 2027 Term Loan is subject to interest at a spread above quoted market rates.

The Credit Facility and the 2027 Term Loan contain customary covenants, including requirements to maintain certain financial ratios, that determine the events of default, amounts available, and terms of borrowings. The Company was in compliance with all applicable covenants at both December 31, 2025 and 2024.
Fair Value of Borrowings

Eastman has classified its total borrowings at December 31, 2025 and 2024 under the fair value hierarchy as defined in the accounting policies in Note 1, "Significant Accounting Policies". The fair value for fixed-rate debt securities is based on quoted market prices for the same or similar debt instruments and is classified as Level 2. The fair value for the Company's other borrowings under the Term Loan equals the carrying value and is classified as Level 2. At December 31, 2025 and 2024, the fair value of total borrowings was $4.7 billion and $4.9 billion, respectively. The Company had no borrowings classified as Level 1 or Level 3 as of December 31, 2025 and 2024.

Derivative Instruments and Hedging Activities Disclosure [Abstract]  
Derivative Instruments and Hedging Activities Disclosure [Text Block] DERIVATIVE AND NON-DERIVATIVE FINANCIAL INSTRUMENTS
Overview of Hedging Programs

Eastman is exposed to market risks, such as changes in foreign currency exchange rates, commodity prices, and interest rates. To mitigate these market risks and their effects on the cash flows of the underlying transactions and investments in foreign subsidiaries, the Company uses various derivative and non-derivative financial instruments, when appropriate, in accordance with the Company's hedging strategy and policies. Designation is performed on a specific exposure basis to support hedge accounting. The Company does not enter into derivative transactions for speculative purposes.

Cash Flow Hedges

Cash flow hedges are derivative instruments designated as and used to hedge the exposure to variability in expected future cash flows that are attributable to a particular risk. The derivative instruments that are designated and qualify as a cash flow hedge are reported on the balance sheet at fair value and the changes in fair value of these hedging instruments are offset in part or in whole by corresponding changes in the anticipated cash flows of the underlying exposures being hedged. The change in the hedge instrument is reported as a component of AOCI located in the Consolidated Statements of Financial Position and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Cash flows from
cash flow hedges are classified as operating activities in the Consolidated Statements of Cash Flows.

Foreign Currency Exchange Rate Hedging 

Eastman manufactures and sells its products in a number of countries throughout the world and, as a result, is exposed to changes in foreign currency exchange rates. To manage the volatility relating to these exposures, the Company nets the exposures on a consolidated basis to take advantage of natural offsets. To manage the remaining exposure, the Company enters into currency option and forward cash flow hedges to hedge probable anticipated, but not yet committed, export sales and purchase transactions expected within a rolling three year period and denominated in foreign currencies (principally the euro). Additionally, the Company, from time to time, enters into forward exchange contracts to hedge certain firm commitments denominated in foreign currencies.

In 2024, the Company de-designated and monetized certain forward cash flow hedges. The resulting unrealized gain of $13 million was recorded in AOCI and was primarily recognized in earnings in 2025 as the underlying forecasted transactions impacted earnings.

Commodity Hedging

Certain raw material and energy sources used by Eastman, as well as sales of certain commodity products by the Company, are subject to price volatility caused by weather, supply and demand conditions, economic variables, and other unpredictable factors. This volatility is primarily related to the market pricing of benzene, ethane, ethylene, natural gas, paraxylene, and propane. In order to mitigate expected fluctuations in market prices, from time to time, the Company enters into option and forward contracts and designates these contracts as cash flow hedges. The Company currently hedges commodity price risks using derivative financial instrument transactions within a rolling three year period. The Company weights its hedge portfolio more heavily in the first year with declining coverage over the remaining periods.
Interest Rate Hedging 

Eastman's policy is to manage interest expense using a mix of fixed and variable rate debt. To manage interest rate risk effectively, the Company, from time to time, enters into cash flow interest rate derivative instruments, primarily forward starting swaps and treasury locks, to hedge the Company's exposure to movements in interest rates prior to anticipated debt offerings. These instruments are designated as cash flow hedges. 

Fair Value Hedges

Fair value hedges are defined as derivative or non-derivative instruments designated as and used to hedge the exposure to changes in the fair value of an asset or a liability or an identified portion thereof that is attributable to a particular risk. The derivative instruments that are designated and qualify as fair value hedges are reported as "Short-term borrowings" or "Long-term borrowings" on the Consolidated Statements of Financial Position at fair value and the changes in fair value of these hedging instruments are offset in part or in whole by corresponding changes in the anticipated fair value of the underlying exposures being hedged. The net of the change in the hedge instrument and item being hedged for qualifying fair value hedges is recognized in earnings in the same period or periods during which the hedged transaction affects earnings. Cash flows from fair value hedges are classified as operating activities in the Consolidated Statements of Cash Flows.

Interest Rate Hedging 

Eastman's policy is to manage interest expense using a mix of fixed and variable rate debt. To manage the Company's mix of fixed and variable rate debt effectively, from time to time, the Company enters into interest rate swaps in which the Company agrees to exchange the difference between fixed and variable interest amounts calculated by reference to an agreed upon notional principal amount. These swaps are designated as hedges of the fair value of the underlying debt obligations and the interest rate differential is reflected as an adjustment to interest expense over the life of the swaps. 

In 2024, the Company settled $75 million notional amount designated as an interest rate swap on the 3.80% notes due March 2025, resulting in an immaterial cash loss which is included as part of operating activities in the Consolidated Statements of Cash Flows.

Net Investment Hedges

Net investment hedges are defined as derivative or non-derivative instruments designated as and used to hedge the foreign currency exposure of the net investment in certain foreign operations. The net of the change in the hedge instrument and item being hedged for qualifying net investment hedges is reported as a component of the "Cumulative Translation Adjustment" ("CTA") within AOCI located in the Consolidated Statements of Financial Position. Cash flows from the CTA component are classified as operating activities in the Consolidated Statements of Cash Flows. Recognition in earnings of amounts previously recognized in CTA is limited to circumstances such as complete or substantially complete liquidation of the net investment in the hedged foreign operation. In the event of a complete or substantially complete liquidation of the net investment, cash flows from net investment hedges are classified as investing activities in the Consolidated Statements of Cash Flows.

For derivative cross-currency interest rate swap net investment hedges, gains and losses representing hedge components excluded from the assessment of effectiveness are recognized in CTA within AOCI and recognized in earnings through the periodic swap interest accruals. The cross-currency interest rate swaps designated as net investment hedges are included as part of "Other long-term liabilities", "Other noncurrent assets", "Payables and other current liabilities", or "Other current assets" on the Consolidated Statements of Financial Position. Cash flows from excluded components are classified as operating activities in the Consolidated Statements of Cash Flows.

Eastman enters into fixed-to-fixed cross-currency swaps and designates these swaps to hedge a portion of its net investment in a non-U.S. dollar functional currency denominated subsidiary against foreign currency fluctuations. These contracts involve the exchange of fixed U.S. dollars with fixed foreign currency interest payments periodically over the life of the contracts and an exchange of the notional amounts at maturity.

In 2025, the Company entered into fixed-to-fixed cross-currency swaps of $50 million (¥7.9 billion) maturing December 2028, $50 million (€48 million) maturing December 2028, $250 million (€226 million) maturing August 2029, and $250 million (€226 million) maturing February 2034.
Additionally, in 2025, Eastman voluntarily terminated and reentered into fixed-to-fixed cross-currency swaps of $245 million (€229 million terminated; €236 million reentered) maturing December 2028, and $300 million (€282 million terminated; €290 million reentered) maturing March 2033. The Company also voluntarily terminated fixed-to-fixed cross-currency swaps of $50 million (¥7.4 billion) maturing March 2025, and $375 million (€351 million) maturing March 2025. The termination of cross-currency swaps in 2025 resulted in a $2 million loss recognized in CTA. The related cash flows were classified as investing activities in the Consolidated Statements of Cash Flows.

In 2024, Eastman entered into fixed-to-fixed cross-currency swaps of $50 million (€46 million) maturing December 2028, $200 million (€184 million) maturing September 2029, and $250 million (€230 million) maturing February 2034. Also in 2024, in conjunction with the repayment of the 7.25% debentures due January 2024, the Company terminated fixed-to-fixed cross-currency swaps of $190 million (€165 million) maturing January 2024. The termination of the cross-currency swap resulted in a $9 million gain recognized in CTA. Additionally, in conjunction with the partial repayment of the 3.80% notes due March 2025, the Company terminated a fixed-to-fixed cross-currency swap of $120 million (€104 million) maturing in March 2025. The termination of this cross-currency swap resulted in a $7 million gain recognized in CTA. The related cash flows were classified as investing activities in the Consolidated Statements of Cash Flows.

In 2023, Eastman entered into fixed-to-fixed cross-currency swaps of $300 million (€283 million) maturing March 2033, $50 million (¥6.7 billion) maturing March 2025, $375 million (€340 million) maturing March 2025, and $125 million (€113 million) maturing December 2028. Additionally, Eastman voluntarily terminated and reentered into fixed-to-fixed cross-currency swaps of $375 million (€340 million terminated; €351 million reentered) maturing March 2025, $305 million (€265 million terminated; €285 million reentered) maturing December 2028, and $50 million (¥6.7 billion terminated; ¥7.4 billion reentered) maturing March 2025. The termination of cross-currency swaps in 2023 resulted in a $34 million gain recognized in CTA. The related cash flows were classified as investing activities in the Consolidated Statements of Cash Flows.

Fair Value Measurements

For additional information on fair value measurement, see Note 1, "Significant Accounting Policies".
All the Company's derivative assets and liabilities are currently classified as Level 2. Level 2 fair value is based on estimates using standard pricing models. These standard pricing models use inputs that are derived from, or corroborated by, observable market data such as interest rate yield curves and currency spot and forward rates. The fair value of commodity contracts is derived using forward curves supplied by an industry recognized and unrelated third party. In addition, on an ongoing basis, the Company compares a subset of its valuations against valuations received from the counterparties to validate the accuracy of its standard pricing models. The Company had no derivatives classified as Level 1 or Level 3 as of December 31, 2025 or December 31, 2024. Counterparties to these derivative contracts are highly rated financial institutions which the Company believes carry minimal risk of nonperformance, and the Company diversifies its positions among such counterparties to reduce its exposure to counterparty risk and credit losses. The Company monitors the creditworthiness of its counterparties on an ongoing basis. The Company did not realize a credit loss related to these counterparties during the years ended December 31, 2025 or 2024.

All the Company's derivative contracts are subject to master netting arrangements, or similar agreements, which provide for the option to settle contracts on a net basis when they settle on the same day and in the same currency. In addition, these arrangements provide for a net settlement of all contracts with a given counterparty in the event that the arrangement is terminated due to the occurrence of default or a termination event. The Company does not have any cash collateral due under such agreements.

The Company presents derivative contracts on a gross basis within the Consolidated Statements of Financial Position. The following table presents the financial assets and liabilities valued on a recurring and gross basis and includes where the financial assets and liabilities are located within the Consolidated Statements of Financial Position as of December 31, 2025 and 2024.

The Company enters into foreign exchange derivatives denominated in multiple currencies which are transacted and settled in the same quarter. These derivatives are not designated as hedges due to the short-term nature and the gains or losses on these derivatives are marked-to-market in the line item "Other (income) charges, net" of the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings. The Company recognized a net gain of $11 million in 2025, a net gain of $1 million in 2024, and net loss of $5 million in 2023 on these derivatives.

Pre-tax monetized positions and MTM gains and losses from raw materials and energy, currency, and certain interest rate hedges that were included in AOCI included losses of $119 million at December 31, 2025 and gains of $154 million at December 31, 2024. The change in AOCI in 2025 compared to 2024 is primarily a result of an increase in foreign currency exchange rates, particularly the euro. If realized, approximately $26 million in pre-tax losses will be reclassified into earnings during the next 12 months, including foreign exchange contracts prospectively dedesignated and monetized in 2024.

Leases [Abstract]  
Commitments and Contingencies Disclosure [Text Block] LEASES AND OTHER COMMITMENTS
Leases

There are two types of leases: financing and operating. Both types of leases have associated right-to-use assets and lease liabilities that are valued at the net present value of the lease payments and recognized on the Consolidated Statements of Financial Position. The discount rate used in the measurement of a right-to-use asset and lease liability is the rate implicit in the lease whenever that rate is readily determinable. If the rate implicit in the lease is not readily determinable, the collateralized incremental borrowing rate is used. The Company elected the accounting policy not to apply the recognition and measurement requirements to short-term leases with a term of 12 months or less and do not include a bargain purchase option.

The Company has operating leases, as a lessee, with customary terms that do not include: significant variable lease payments; significant reasonably certain extensions or options required to be included in the lease term; restrictions; or other covenants for real property, rolling stock, and machinery and equipment. Real property leases primarily consist of office space and rolling stock leases primarily for railcars and fleet vehicles. At December 31, 2025 and 2024, right-to-use assets for operating leases of $191 million and $164 million, respectively, are included as a part of "Other noncurrent assets" on the Consolidated Statements of Financial Position. At both December 31, 2025 and 2024, the operating right-to-use assets include $3 million of assets previously classified as lease intangibles and $6 million and $7 million of prepaid lease assets, respectively. Operating lease liabilities are included as a part of "Payables and other current liabilities" and "Other long-term liabilities" on the Consolidated Statements of Financial Position. As of December 31, 2025, financing leases were not material to the Company's financial statements.

As of December 31, 2025, reconciliation of lease payments and operating lease liabilities is provided below:

The Company has operating leases, primarily leases for railcars, with terms that require the Company to guarantee a portion of the residual value of the leased assets upon termination of the lease that will expire beginning first quarter 2026. Residual guarantee payments that become probable and estimable are recognized as rent expense over the remaining life of the applicable lease. Management's current expectation is that the likelihood of material residual guarantee payments is remote.

Estimated future payments of debt securities assumes the repayment of principal upon stated maturity, and actual amounts and the timing of such payments may differ materially due to repayment or other changes in the terms of such debt prior to maturity.

Eastman had various purchase obligations at December 31, 2025 totaling $1.8 billion over a period of approximately 25 years for materials, supplies, and energy incident to the ordinary conduct of business. 

Amounts in other liabilities represent the current estimated cash payments required to be made by the Company primarily for pension and other postretirement benefits, accrued compensation benefits, environmental loss contingency estimates, uncertain tax liabilities, and commodity and foreign exchange hedging in the periods indicated. Due to uncertainties in the timing of the effective settlement of tax positions with respect to taxing authorities, management is unable to determine the timing of payments related to uncertain tax liabilities and these amounts are included in the "2031 and beyond" line item.
The amount and timing of pension and other postretirement benefit payments included in other liabilities is dependent upon interest rates, health care cost trends, actual returns on plan assets, retirement and attrition rates of employees, continuation or modification of the benefit plans, and other factors. Such factors can significantly impact the amount and timing of any future contributions by the Company. Excess contributions are periodically made by management in order to keep the plans' funded status above 80 percent under the funding provisions of the Pension Protection Act to avoid partial benefit restrictions on accelerated forms of payment. The Company's U.S. defined benefit pension plans are not currently under any benefit restrictions. See Note 11, "Retirement Plans", for more information regarding pension and other postretirement benefit obligations.

The resolution of uncertainties related to environmental matters included in other liabilities may have a material adverse effect on the Company's consolidated results of operations in the period recognized, however, because of the availability of legal defenses, the Company's preliminary assessment of actions that may be required, and, if applicable, the expected sharing of costs, management does not believe that the Company's liability for these environmental matters, individually or in the aggregate, will be material to the Company's consolidated financial position, results of operations, or cash flows. See "Environmental Costs" in Note 1, "Significant Accounting Policies", and see Note 13, "Environmental Matters and Asset Retirement Obligations", for more information regarding outstanding environmental matters and asset retirement obligations.

Guarantees and claims also arise during the ordinary course of business from relationships with customers, suppliers, joint venture partners, and other parties when the Company undertakes an obligation to guarantee the performance of others if specified triggering events occur. Non-performance under a contract could trigger an obligation of the Company. The Company's current other guarantees include guarantees relating to intellectual property, third-party debt, and other indemnifications and have arisen through the normal course of business. The ultimate effect on future financial results is not subject to reasonable estimation because considerable uncertainty exists as to the final outcome of these claims, if they were to occur. These other guarantees have remaining terms up to 15 years with maximum potential future payments of approximately $146 million in the aggregate, with none of these guarantees being individually significant to the Company's operating results, financial position, or liquidity. Management's current expectation is that future payment or performance related to non-performance under other guarantees is remote. Eastman has letters of credit and surety bonds of approximately $95 million as of December 31, 2025 to support commitments made in the ordinary course of business. The Company does not expect that any claims against or draws on these instruments would have a material adverse effect on the Company.

Environmental Matters [Abstract]  
ENVIRONMENTAL MATTERS ENVIRONMENTAL MATTERS AND ASSET RETIREMENT OBLIGATIONS
Certain Eastman manufacturing facilities generate hazardous and nonhazardous wastes, of which the treatment, storage, transportation, and disposal are regulated by various governmental agencies. In connection with the cleanup of various hazardous waste sites, the Company, along with many other entities, has been designated a potentially responsible party ("PRP") by the U.S. Environmental Protection Agency under the Comprehensive Environmental Response, Compensation and Liability Act, which potentially subjects PRPs to joint and several liability for certain cleanup costs. In addition, the Company will incur costs for environmental remediation and closure and post-closure under the federal Resource Conservation and Recovery Act. Reserves for environmental contingencies have been established in accordance with Eastman's policies described in Note 1, "Significant Accounting Policies". The resolution of uncertainties related to environmental matters may have a material adverse effect on the Company's consolidated financial statements and related disclosures in the period recognized. However, because of the availability of legal defenses, the Company's preliminary assessment of actions that may be required, and the extended period of time that the obligations are expected to be satisfied, management does not believe that the Company's liability for these environmental matters, individually or in the aggregate, will have a material adverse effect on the Company's future overall financial position, results of operations, or cash flows.

Environmental Remediation and Environmental Asset Retirement Obligations

The Company's net environmental reserve for environmental contingencies, including remediation costs and asset retirement obligations, is included as part of "Other noncurrent assets", "Payables and other current liabilities", and "Other long-term liabilities" on the Consolidated Statements of Financial Position as follows:
(Dollars in millions)December 31,

Environmental contingencies, current$20 $15 
Environmental contingencies, long-term298 269

Environmental Remediation

Estimated future environmental expenditures for undiscounted remediation costs ranged from $285 million to $509 million and from $252 million to $495 million at December 31, 2025 and 2024, respectively. The best estimate or minimum estimated future environmental expenditures of $285 million and $252 million at December 31, 2025 and 2024, respectively, are considered to be probable and reasonably estimable.

Costs of certain remediation projects included in the environmental reserve are subject to a cost-sharing arrangement with Monsanto Company ("Monsanto") under the provisions of the Amended and Restated Settlement Agreement effective February 28, 2008 (the "Effective Date"), into which Solutia entered with Monsanto upon its emergence from bankruptcy (the "Monsanto Settlement Agreement"). Under the provisions of the Monsanto Settlement Agreement, Solutia, which became a wholly-owned subsidiary of Eastman on July 2, 2012, shares responsibility with Monsanto for remediation at certain locations outside of the boundaries of plant sites in Anniston, Alabama and Sauget, Illinois (the "Shared Sites"). Solutia is responsible for the funding of environmental liabilities at the Shared Sites up to a total of $325 million from the Effective Date. If remediation costs for the Shared Sites exceed this amount, such costs will thereafter be shared equally between Solutia and Monsanto. Including payments by Solutia prior to its acquisition by Eastman, $140 million had been paid for costs at the Shared Sites as of December 31, 2025. As of December 31, 2025, an additional $229 million has been recognized for estimated future remediation costs at the Shared Sites, over a period of approximately 30 years.

Reserves for environmental remediation include liabilities expected to be paid within approximately 30 years. Eastman has letters of credit of approximately $155 million to support certain environmental matters. The Company does not expect that any claims against or draws on these instruments would have a material adverse effect on the Company. The amounts charged to pre-tax earnings for environmental remediation and related charges are recognized in "Cost of sales" and "Other (income) charges, net" on the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings.

Changes in the reserves for environmental remediation liabilities during 2025 and 2024 are summarized below:

Environmental Asset Retirement Obligations

An asset retirement obligation is an obligation for the retirement of a tangible long-lived asset that is incurred upon the acquisition, construction, development, or normal operation of that long-lived asset. Environmental asset retirement obligations consist primarily of closure and post-closure costs. For sites that have environmental asset retirement obligations, the best estimate recognized to date for these environmental asset retirement obligation costs were $33 million and $32 million December 31, 2025 and December 31, 2024, respectively. 

Other

Eastman's cash expenditures related to environmental protection and improvement were $339 million, $307 million, and $314 million in 2025, 2024, and 2023, respectively, and include operating costs associated with environmental protection equipment and facilities, engineering costs, and construction costs. The cash expenditures above include environmental capital expenditures of approximately $80 million, $70 million, and $65 million in 2025, 2024, and 2023, respectively.
The Company has contractual asset retirement obligations not associated with environmental liabilities. Eastman's non-environmental asset retirement obligations are primarily associated with the future closure of leased manufacturing assets in Pace, Florida and Oulu, Finland. These non-environmental asset retirement obligations were $56 million and $53 million at December 31, 2025 and December 31, 2024, respectively, and are included in "Other long-term liabilities" on the Consolidated Statements of Financial Position.

Eastman is authorized to issue 400 million shares of all classes of stock, of which 50 million may be preferred stock, par value $0.01 per share, and 350 million may be common stock, par value $0.01 per share. The Company declared dividends per share of $3.33 in 2025, $3.26 in 2024, and $3.18 in 2023.

In 1997 the Company established a benefit security trust to provide a degree of financial security for unfunded obligations under certain unfunded plans. A warrant to purchase up to 6 million shares of par value common stock of the Company was contributed to the trust. The warrant, which remains outstanding, is exercisable by the trustee if the Company does not meet certain funding obligations, which obligations would be triggered by certain occurrences, including a change in control or potential change in control, as defined, or failure by the Company to meet its payment obligations under certain covered unfunded plans. The warrant is excluded from the computation of diluted EPS because the conditions upon which the warrant becomes exercisable have not been met.
In December 2021, the Company's Board of Directors authorized the repurchase of up to $2.5 billion of the Company's outstanding common stock at such times, in such amounts, and on such terms, as determined by management to be in the best interest of the Company and its stockholders (the "2021 authorization"). As of December 31, 2025, a total of 13,032,926 shares have been repurchased under the 2021 authorization for $1.2 billion. Both dividends and share repurchases are key strategies employed by the Company to return value to its stockholders.

During 2025, the Company repurchased 1,420,768 shares of common stock for $100 million. During 2024, the Company repurchased 3,001,409 shares of common stock for a cost of $300 million. During 2023, the Company repurchased 1,866,866 shares of common stock for a cost of $150 million.

The Company's charitable foundation held 50,798 issued and outstanding shares of the Company's common stock at December 31, 2025, 2024, and 2023 which are included in treasury stock in the Consolidated Statements of Financial Position and excluded from calculations of diluted EPS.

SHARE-BASED COMPENSATION PLANS AND AWARDS

Share-Based Payment Arrangement [Abstract]  
SHARE-BASED COMPENSATION PLANS AND AWARDS SHARE-BASED COMPENSATION PLANS AND AWARDS
2021 Omnibus Stock Compensation Plan

Eastman's 2021 Omnibus Stock Compensation Plan ("2021 Omnibus Plan") was approved by stockholders at the May 6, 2021 Annual Meeting of Stockholders and shall remain in effect until its fifth anniversary. The 2021 Omnibus Plan authorizes the Compensation and Management Development Committee of the Board of Directors to grant awards, designate participants, determine the types and numbers of awards, determine the terms and conditions of awards and determine the form of award settlement. Under the 2021 Omnibus Plan, the aggregate number of shares reserved and available for issuance is 10 million, which consist of shares not previously authorized for issuance under any other plan. The number of shares covered by an award is counted against this share reserve as of the grant date of the award. Shares covered by full value awards (e.g., performance shares and restricted stock awards) are counted against the total number of shares available for issuance or delivery under the plan as 2.5 shares for every one share covered by the award. Any stock distributed pursuant to an award may consist of, in whole or in part, authorized and unissued stock, treasury stock, or stock purchased on the open market. Under the 2021 Omnibus Plan and previous plans, the forms of awards have included restricted stock and restricted stock units, stock options, stock appreciation rights ("SARs"), and performance shares. The 2021 Omnibus Plan is flexible as to the number of specific forms of awards, but provides that stock options and SARs are to be granted at an exercise price not less than 100 percent of the per share fair market value on the date of the grant.
 
Director Stock Compensation Subplan

Eastman's Amended 2021 Director Stock Compensation Subplan ("Directors' Subplan"), a component of the 2021 Omnibus Plan, remains in effect until terminated by the Board of Directors or the earlier termination of the 2021 Omnibus Plan. The Directors' Subplan provides for structured awards of restricted shares to non-employee members of the Board of Directors. Restricted shares awarded under the Directors' Subplan are subject to the same terms and conditions of the 2021 Omnibus Plan. The Directors' Subplan does not constitute a separate source of shares for grants of equity awards and all shares awarded are part of the 10 million shares authorized under the 2021 Omnibus Plan. Shares of restricted stock are granted on the first day of a non-employee director's initial term of service and shares of restricted stock are granted each year to each non-employee director on the date of the annual meeting of stockholders.

It has been the Company's practice to issue new shares rather than treasury shares for equity awards for compensation plans, including the 2021 Omnibus Plan and the Directors' Subplan, that require settlement by the issuance of common stock and to withhold or accept back shares awarded to cover the related income tax obligations of employee participants. Shares of unrestricted common stock owned by non-employee directors are not eligible to be withheld or acquired to satisfy the withholding obligation related to their income taxes. Shares of unrestricted common stock owned by specified senior management level employees are accepted by the Company to pay the exercise price of stock options in accordance with the terms and conditions of their awards.
Compensation Expense

For 2025, 2024, and 2023, total share-based compensation expense (before tax) of $48 million, $63 million, and $64 million, respectively, was recognized in "Selling, general and administrative expense" in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings for all share-based awards of which $10 million, $8 million, and $10 million, respectively, related to stock options. The compensation expense is recognized over the substantive vesting period, which may be a shorter time period than the stated vesting period for qualifying termination eligible employees as defined in the forms of award notice. Stock option compensation expense of $8 million for 2025, $6 million for 2024, and $6 million for 2023 was recognized each year due to qualifying termination eligibility preceding the requisite vesting period.

Stock Option Awards

Options have been granted on an annual basis by the Compensation and Management Development Committee of the Board of Directors under the 2021 Omnibus Plan and predecessor plans to employees. Option awards have an exercise price equal to the closing price of the Company's stock on the date of grant. The term of the options is 10 years with vesting periods that vary up to three years. Vesting usually occurs ratably over the vesting period or at the end of the vesting period. The Company utilizes the Black Scholes Merton option valuation model which relies on certain assumptions to estimate an option's fair value.

The weighted average assumptions used in the determination of fair value for the options awarded in 2025, 2024, and 2023 are provided in the table below:
Assumptions202520242023
Expected volatility rate30.61%30.21%30.55%
Expected dividend yield3.32%3.82%3.31%
Average risk-free interest rate4.42%4.34%4.13%
Expected term years6.86.76.4

The volatility rate of grants is derived from historical Company common stock price volatility over the same time period as the expected term of each stock option award. The volatility rate is derived by a mathematical formula utilizing the weekly high closing stock price data over the expected term. The expected dividend yield is calculated using the Company's average of the last four quarterly dividend yields. The average risk-free interest rate is derived from the United States Department of Treasury's published interest rates of daily yield curves for the same time period as the expected term. The weighted average expected term reflects the analysis of historical share-based award transactions and includes option swap and reload grants which may have much shorter remaining expected terms than new option grants.

A summary of the activity of the Company's stock option awards for 2025, 2024, and 2023 is presented below:

 3,791,0005.0$91 3,006,100$90 

The range of exercise prices of options outstanding at December 31, 2025 is approximately $61 to $121 per share. The aggregate intrinsic value of total options outstanding and total options exercisable at December 31, 2025 is $1 million and $1 million, respectively. Intrinsic value is the amount by which the closing market price of the stock at December 31, 2025 exceeds the exercise price of the option grants.

The weighted average remaining contractual life of all exercisable options at December 31, 2025 is 4.1 years.

The weighted average fair value of options granted during 2025, 2024, and 2023 was $26.99, $21.16, and $21.67, respectively. The total intrinsic value of options exercised during the years ended December 31, 2025, 2024, and 2023, was $1 million, $16 million, and $1 million, respectively. Cash proceeds received by the Company from option exercises totaled $3 million with an
immaterial tax benefit for 2025, $41 million with a $2 million related tax benefit for 2024, and $3 million with an immaterial tax benefit for 2023. The total fair value of shares vested during the years ending December 31, 2025, 2024, and 2023 was $9 million, $9 million, and $8 million, respectively.

A summary of the changes in the Company's nonvested options during the year ended December 31, 2025 is presented below:
Nonvested OptionsNumber of OptionsWeighted-Average Grant Date Fair Value

784,900 $24.28

For nonvested options at December 31, 2025, approximately $1 million in compensation expense will be recognized over the next two years.
Other Share-Based Compensation Awards

In addition to stock option awards, Eastman has awarded long-term performance share awards, restricted stock awards, and SARs. The long-term performance share awards are based upon actual return on capital compared to a target return on capital and total stockholder return compared to a peer group ranking by total stockholder return over a three year performance period. The awards are valued using a Monte Carlo Simulation based model and vest pro-rata over the three year performance period. The number of long-term performance award target shares granted for the 2025-2027, 2024-2026, and 2023-2025 periods were 332 thousand, 339 thousand, and 406 thousand, respectively. The target shares are assumed to be 100 percent of the target shares granted based on the award notice. At the end of the three-year performance period, the actual number of shares awarded can range from zero percent to 250 percent of the target shares granted based on the award notice. The number of restricted stock awards granted during 2025, 2024, and 2023 were 176 thousand, 276 thousand, and 144 thousand, respectively. The fair value of a restricted stock award is equal to the closing stock price of the Company's stock on the date of grant and normally vests over a period of three years. The recognized compensation expense before tax for these other share-based awards in the years ended December 31, 2025, 2024, and 2023 was $38 million, $54 million, and $55 million, respectively. The unrecognized compensation expense before tax for these same type of awards at December 31, 2025 was approximately $61 million and will be recognized primarily over a period of two years.

Segment Reporting [Abstract]  
SEGMENT INFORMATION SEGMENT AND REGIONAL SALES INFORMATION
Eastman's products and operations are managed and reported in four operating segments: Advanced Materials ("AM"), Additives & Functional Products ("AFP"), Chemical Intermediates ("CI"), and Fibers. The economic factors that impact the nature, amount, timing, and uncertainty of revenue and cash flows vary among the Company's operating segments and the geographical regions in which they operate. "Other" includes sales and costs related to growth initiatives, including the cellulosics biopolymer and circular economy platforms, research and development ("R&D") costs, certain components of pension and other postretirement benefits, and other expenses and income not identifiable to an operating segment and is not included in operating segment results. This operating segment structure is used by the Chief Operating Decision Maker ("CODM"), who has been determined to be the Chief Executive Officer, to make key operating decisions and assess performance of the Company. The CODM evaluates segment operating performance, and makes resource allocation and performance evaluation decisions, based on Adjusted EBIT, defined as the GAAP measure earnings before interest and taxes ("EBIT"), adjusted for non-core, unusual, or non-recurring items. These adjustments allow the CODM to evaluate segment operating performance excluding the effect of transactions, costs, and losses or gains that do not directly result from Eastman's normal, or "core", business and operations, or are otherwise of an unusual or non-recurring nature.

Advanced Materials Segment

In the AM segment, the Company produces and markets polymers, films, and plastics with differentiated performance properties for value-added end-uses in transportation; durables and electronics; building and construction; medical and pharma; and consumables end-markets.

The advanced interlayers product line includes polyvinyl butyral sheet and polyvinyl butyral intermediates. The performance films product line primarily consists of window films and protective films products for aftermarket applied films. The specialty plastics product line consists of two primary products: copolyesters and cellulosic biopolymers.

Financial Statement Presentation
Financial Statement Presentation

The consolidated financial statements of Eastman Chemical Company ("Eastman" or the "Company") and subsidiaries are prepared in conformity with accounting principles generally accepted ("GAAP") in the United States and of necessity include some amounts that are based upon management estimates and judgments. Future actual results could differ from such current estimates and judgments. The consolidated financial statements include assets, liabilities, sales revenue, and expenses of all majority-owned subsidiaries and joint ventures in which a controlling interest is maintained. Eastman accounts for other joint ventures and investments in minority-owned companies where it exercises significant influence on the equity basis. Intercompany transactions and balances are eliminated in consolidation. Certain prior period data has been reclassified in the consolidated financial statements and accompanying footnotes to conform to current period presentation.
New Accounting Pronouncements
Recently Adopted Accounting Standards

Accounting Standards Update ("ASU") 2023-05 Business Combination - Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement: On January 1, 2025, Eastman adopted this update, which requires that a joint venture must initially measure all contributions received upon its formation at fair value, largely consistent with Topic 805, Business Combinations. The guidance is intended to reduce diversity in practice and provide users of joint venture financial statements with more decision-useful information. This ASU is applied prospectively for all newly formed joint venture entities with a formation date on or after January 1, 2025. The adoption did not have a material impact on the Company's financial statements and related disclosures.

ASU 2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures: On January 1, 2025, Eastman adopted this update on a prospective basis, which modifies annual income tax disclosure requirements. The updated guidance mandates entities to provide more detailed information including specific categories in the income tax rate reconciliation, and the breakdown of income or loss from continuing operations before income tax expense or benefit, for both domestic and foreign. Additionally, entities must disclose income tax expense or benefit from continuing operations, categorized by federal, state, and foreign taxes. The guidance further requires disclosure of income tax payments to various jurisdictions. The adoption did not have a material impact on the financial statements. See Note 8, "Income Taxes" for related disclosures.

Accounting Standards Issued But Not Adopted as of December 31, 2025

ASU 2024-03 Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses: The Financial Accounting Standards Board ("FASB") issued this update in November 2024, which requires public companies to provide additional disclosure of certain income statement expense line items. This guidance is intended to improve transparency around the nature of expenses and their impact on financial performance. The ASU is effective for fiscal periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027. Early adoption is permitted. Management is currently evaluating the impact of the changes required by the new standard on the Company's financial statements and related disclosures.

ASU 2025-05 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets: The FASB issued this update in July 2025 to address the application of Topic 326 to current accounts receivable and current contract assets arising from transactions accounted for under Topic 606, Revenue from Contracts with Customers. The amendments provide a practical expedient permitting entities, when estimating expected credit losses for those balances, to assume that current conditions at the balance sheet date do not change over the remaining life of the asset. The ASU is effective for fiscal periods beginning after December 15, 2025, including interim periods within those years, with early adoption permitted. The Company expects to elect the practical expedient upon adoption. Management does not expect the changes under the new standard will have a material impact on the Company's financial statements and related disclosures.

ASU 2025-06 Intangibles Goodwill and Other Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software: The FASB issued this update in September 2025, which removes prescriptive development stages and establishes a probable-to-complete recognition threshold under which capitalization of software development costs begins when management has authorized and committed to funding the project and it is probable the project will be completed and used as intended. The ASU is effective for fiscal periods beginning after December 15, 2027, including interim periods within those years, with early adoption permitted. Management is currently evaluating the impact of the changes under the new standard on the Company's financial statements and related disclosures.
ASU 2025-10 Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities: The FASB issued this update in December 2025, which establishes authoritative guidance on the accounting for government grants, including grants related to an asset and grants related to income. The amendments, largely aligned with International Accounting Standards 20, IAS 20, Accounting for Government Grants and Disclosure of Government Assistance ("IAS 20"), require that a government grant not be recognized until it is probable the Company will comply with the conditions attached to the grant and that the grant will be received. The amendments further codify specific recognition approaches for asset-related grants and for income-related grants, with presentation as income or deducted from the related expense. The ASU is effective for fiscal periods beginning after December 15, 2028, including interim periods within those years, with early adoption permitted. Management is currently evaluating the impact of the changes under the new standard on the Company's financial statements and related disclosures.
Revenue Recognition and Customer Incentives
Revenue Recognition

Eastman recognizes revenue when performance obligations of the sale are satisfied. Eastman sells to customers through master sales agreements or standalone purchase orders. The majority of the Company's terms of sale have a single performance obligation to transfer products. Accordingly, the Company recognizes revenue when control has been transferred to the customer, generally at the time of shipment of products.

Eastman accounts for shipping and handling as activities to fulfill the promise to transfer the good and does not allocate revenue to those activities. All related shipping and handling costs are recognized at the time of shipment. Amounts collected for sales or other similar taxes are presented net of the related tax expense rather than presenting them as additional revenue. The incremental cost of obtaining a sales contract is recognized as a selling expense when incurred given the potential amortization period for such an asset is one year or less. The possible existence of a significant financing component within a sales contract is ignored when the time between cash collection and performance is less than one year. Finally, the Company does not disclose any unfulfilled obligations as customer purchase order commitments have an original expected duration of one year or less and no consideration from customers is excluded from the transaction price.

The timing of Eastman's customer billings does not always match the timing of revenue recognition. When the Company is entitled to bill a customer in advance of the recognition of revenue, a contract liability is recognized. When the Company is not entitled to bill a customer until a period after the related recognition of revenue, a contract asset is recognized. Contract assets represent the Company's right to consideration for the exchange of goods under a contract but which are not yet billable to a customer for consignment inventory or pursuant to certain shipping terms. Contract liabilities were $4 million and $15 million as of December 31, 2025 and 2024, respectively, and are included as a part of "Payables and other current liabilities" and "Other long-term liabilities" in the Consolidated Statements of Financial Position. Contract assets were $66 million and $92 million as of December 31, 2025 and 2024, respectively, and are included as a component of "Miscellaneous receivables" in the Consolidated Statements of Financial Position.

For additional information, see Note 20, "Segment and Regional Sales Information".
Pension and Other Postretirement Benefits
Pension and Other Postretirement Benefits

Eastman maintains defined benefit pension and other postretirement benefits plans that provide eligible employees with retirement benefits. The estimated amounts of the costs and obligations related to these benefits reflect the Company's assumptions related to discount rates, expected return on plan assets, rate of compensation increase or decrease for employees, and health care cost trends. The estimated cost of providing plan benefits also depends on demographic assumptions including retirements, mortality, turnover, and plan participation.

Eastman's pension and other postretirement benefit plans costs consist of two elements: 1) ongoing costs recognized quarterly, which are comprised of service and interest costs, expected returns on plan assets, and amortization of prior service credits; and 2) mark-to-market ("MTM") gains and losses recognized annually, in the fourth quarter of each year, primarily resulting from changes in actuarial assumptions for discount rates and the differences between actual and expected returns on plan assets. Any interim remeasurements triggered by a curtailment, settlement, or significant plan changes are recognized in the quarter in which such remeasurement event occurs.

For additional information, see Note 11, "Retirement Plans".

Eastman recognizes environmental remediation costs when it is probable that the Company has incurred a liability at a contaminated site and the amount can be reasonably estimated. When a single amount cannot be reasonably estimated but the cost can be estimated within a range, the Company recognizes the minimum undiscounted amount. This undiscounted amount reflects liabilities expected to be paid within approximately 30 years and the Company's assumptions about remediation requirements at the contaminated site, the nature of the remedy, the outcome of discussions with regulatory agencies and other potentially responsible parties at multi-party sites, and the number and financial viability of other potentially responsible parties. Changes in the estimates on which the accruals are based, unanticipated government enforcement action, or changes in health, safety, environmental, and chemical control regulations and testing requirements could result in higher or lower costs.

The Company also establishes reserves for closure and post-closure costs associated with the environmental and other assets it maintains. Environmental assets include but are not limited to waste management units, such as landfills, water treatment facilities, and surface impoundments. When these types of assets are constructed or installed, a loss contingency reserve is established for the anticipated future costs associated with the retirement or closure of the asset based on its expected life and the applicable regulatory closure requirements. The Company recognizes the asset retirement obligations in the period in which they are incurred if a reasonable estimate of fair value can be made. The asset retirement obligations are discounted to expected present value and subsequently adjusted for changes in fair value. These future estimated costs are charged to earnings over the estimated useful life of the assets. If the Company changes its estimate of the environmental asset retirement obligation costs or its estimate of the useful lives of these assets, earnings will be impacted in the period the estimate is changed. The associated estimated asset retirement costs are capitalized as part of the carrying value of the long-lived assets and depreciated over their useful life and charged to "Cost of sales" in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings.

Environmental costs are capitalized if they extend the life of the related property, increase its capacity, or mitigate the possibility of future contamination. The cost of operating and maintaining environmental control facilities is charged to "Cost of sales" in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings, as incurred.

For additional information see Note 13, "Environmental Matters and Asset Retirement Obligations".
Share-based Compensation
Share-Based Compensation

Eastman recognizes compensation expense in "Selling, general and administrative expense" in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings for stock options and other share-based compensation awards based upon the grant-date fair value over the substantive vesting period. 

For additional information, see Note 18, "Share-Based Compensation Plans and Awards".
Restructuring of Operations
Restructuring of Operations

Eastman records restructuring charges for costs incurred in connection with consolidation of operations, exited business or product lines, or shutdowns of specific sites that are expected to be substantially completed within twelve months. These restructuring charges are recorded as incurred, and are associated with site closures, legal and environmental matters, demolition, contract terminations, or other costs and charges directly related to the restructuring. The Company records severance charges for employee separations when the separation is probable and reasonably estimable. In the event employees are required to perform future service, the Company records severance charges ratably over the remaining service period of those employees.
For additional information, see Note 16, "Asset Impairments, Restructuring, and Other Charges, Net".
Income Taxes
Income Taxes

The provision for income taxes has been determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax bases of Eastman's assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. The recoverability of the Company's deferred tax assets are evaluated each quarter by assessing the likelihood of future profitability and available tax planning strategies that could be implemented to realize the Company's net deferred tax assets. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Provision has been made for income taxes on unremitted earnings of subsidiaries and affiliates, except for subsidiaries in which earnings are deemed to be indefinitely reinvested. The calculation of income tax liabilities involves uncertainties in the application of complex tax laws and regulations, which are subject to legal interpretation and management judgment. Eastman's income tax returns are regularly examined by federal, state and foreign tax authorities, and those audits may result in proposed adjustments. The Company has evaluated these potential issues under the more-likely-than-not standard of the accounting literature. A tax position is recognized if it meets this standard and is measured at the largest amount of benefit that has a greater than 50 percent likelihood of being realized. Such judgments and estimates may change based on audit settlements, court cases and interpretation of tax laws and regulations. The Company accrues interest related to unrecognized income tax positions, which is included as a component of the income tax provision on the balance sheet. The accrued interest related to unrecognized income tax positions and taxes resulting from the global intangible low-tax income are recorded as a component of the income tax provision.
For additional information, see Note 8, "Income Taxes".
Cash and Cash Equivalents
Cash and Cash Equivalents

Cash and cash equivalents include cash, time deposits, and readily marketable securities with original maturities of three months or less.
Fair Value Measurements
Fair Value Measurements

Eastman records recurring and non-recurring financial assets and liabilities as well as all non-financial assets and liabilities subject to fair value measurement at the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. These fair value principles prioritize valuation inputs across three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company's assumptions used to measure assets and liabilities at fair value. An asset or liability's classification within the various levels is determined based on the lowest level input that is significant to the fair value measurement.
Accounts Receivable and Allowance for Doubtful Accounts
Accounts Receivable and Allowance for Credit Losses

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Eastman maintains allowances for estimated credit losses, which are developed at a market, country, and region level based on risk of collection as well as current and forecasted economic conditions. The Company calculates the allowance based on an assessment of the risk when the accounts receivable is recognized. Write-offs are recorded at the time a customer receivable is deemed uncollectible. Allowance for credit losses were $14 million and $15 million as of December 31, 2025 and 2024, respectively. The Company does not enter into receivables of a long-term nature, also known as financing receivables, in the normal course of business.
Inventories
Inventories

Inventories measured by the last-in, first-out ("LIFO") method are valued at the lower of cost or market and inventories measured by the first-in, first-out ("FIFO") method are valued at the lower of cost or net realizable value. Eastman determines the cost of most raw materials, work in process, and finished goods inventories in the United States and Switzerland by the LIFO method. The cost of all other inventories is determined by the average cost method, which approximates the FIFO method. The Company writes-down its inventories equal to the difference between the carrying value of inventory and the estimated market value or net realizable value based upon assumptions about future demand and market conditions.
For additional information, see Note 3, "Inventories".
Properties
Properties

Eastman records properties at cost. Maintenance and repairs are charged to earnings; replacements and betterments are capitalized. When Eastman retires or otherwise disposes of assets, it removes the cost of such assets and related accumulated depreciation from the accounts. The Company records any profit or loss on retirement or other disposition in "Cost of sales" in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings. Asset impairments are reflected as increases in accumulated depreciation for properties that have been placed in service. In instances when an asset has not been placed in service and is impaired, the associated costs are removed from the appropriate property accounts.
For additional information, see Note 4, "Properties and Accumulated Depreciation" and Note 16, "Asset Impairments, Restructuring, and Other Charges, Net".
Depreciation and Amortization
Depreciation and Amortization

Depreciation expense is calculated based on historical cost and the estimated useful lives of the assets, generally using the straight-line method. Estimated useful lives for buildings and building equipment generally range from 20 to 50 years. Estimated useful lives generally ranging from 3 to 33 years are applied to machinery and equipment in the following categories: computer software (3 to 5 years); office furniture and fixtures and computer equipment (5 to 10 years); vehicles, railcars, and general machinery and equipment (5 to 20 years); and manufacturing-related improvements (20 to 33 years). Accelerated depreciation is reported when the estimated useful life is shortened and continues to be reported in "Cost of sales" in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings.

For additional information, see Note 4, "Properties and Accumulated Depreciation".

Amortization expense for definite-lived intangible assets is generally determined using a straight-line method over the estimated useful life of the asset. Amortization expense is reported in "Cost of sales" in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings.
For additional information, see Note 5, "Goodwill and Other Intangible Assets".
Impairment of Long Lived Assets
Impairment of Long-Lived Assets

Definite-lived Assets

Properties and equipment and definite-lived intangible assets to be held and used by Eastman are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The review of properties and equipment and the review of definite-lived intangible assets is performed at the asset group level, which is the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. If the carrying amount is not considered to be recoverable, an analysis of fair value is triggered. An impairment is recognized for the excess of the carrying amount of the asset over the estimated fair value.
Goodwill and Intangible Assets, Policy
Goodwill

Goodwill is an asset determined as the residual of the purchase price over the fair value of identified assets and liabilities
acquired in a business combination. Eastman conducts testing of goodwill for impairment annually in the fourth quarter or more frequently when events and circumstances indicate an impairment may have occurred. The testing of goodwill is performed at the "reporting unit" level which the Company has determined to be its "components". Components are defined as an operating segment or one level below an operating segment, and in order to be a reporting unit, the component must (1) be a "business" as defined by applicable accounting standards (an integrated set of activities and assets that is capable of being conducted and managed for the purpose of providing a return in the form of dividends, lower costs, or other economic benefits directly to the investors or other owners, members, or participants); (2) have discrete financial information available; and (3) be reviewed regularly by Company operating segment management. The Company aggregates certain components into reporting units based on economic similarities. An impairment is recognized when the reporting unit's estimated fair value is less than its carrying value. The Company may use a qualitative analysis or a quantitative analysis in testing the carrying value of goodwill of each reporting unit for impairment. When the quantitative analysis is used, the Company uses an income approach, specifically a discounted cash flow model.

Indefinite-lived Intangible Assets

Eastman conducts testing of indefinite-lived intangible assets annually in the fourth quarter or more frequently when events and circumstances indicate an impairment may have occurred. The carrying value of an indefinite-lived intangible asset is considered to be impaired when the fair value, estimated by appraisal or based on discounted future cash flows of certain related products, is less than the respective carrying value.

Indefinite-lived intangible assets, consisting primarily of various tradenames, are tested for potential impairment by comparing the estimated fair value to the carrying amount. The Company may use a qualitative analysis or a quantitative analysis in testing the carrying value of indefinite-lived intangible assets for impairment. When the quantitative analysis is used, the Company uses an income approach, specifically the relief from royalty method. The estimated fair value of tradenames is determined based on an assumed royalty rate savings, discounted by the calculated market participant estimated weighted average cost of capital ("WACC") plus a risk premium.
For additional information, see Note 5, "Goodwill and Other Intangible Assets".
Lessee, Leases [Policy Text Block]
Leases

There are two types of leases: financing and operating. Both types of leases have associated right-to-use assets and lease liabilities that are valued at the net present value of the lease payments and recognized on the Consolidated Statements of Financial Position. The discount rate used in the measurement of a right-to-use asset and lease liability is the rate implicit in the lease whenever that rate is readily determinable. If the rate implicit in the lease is not readily determinable, the collateralized incremental borrowing rate is used. The Company elected the accounting policy not to apply the recognition and measurement requirements to short-term leases with a term of 12 months or less and do not include a bargain purchase option. Residual guarantee payments that become probable and estimable are recognized as rent expense over the remaining life of the applicable lease.

For lease accounting policies, see Note 12, "Leases and Other Commitments".
Investments
Investments

The consolidated financial statements include the accounts of Eastman and all its subsidiaries and entities or joint ventures in which a controlling interest is maintained. The Company includes its share of earnings and losses of such investments in "Net earnings attributable to Eastman" and "Comprehensive income attributable to Eastman" located in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings and in "Total equity" located in the Consolidated Statements of Financial Position.

Investments in affiliates over which the Company has significant influence but not a controlling interest are accounted for under the equity method of accounting. These investments are included in "Other noncurrent assets" in the Consolidated Statements of Financial Position. The Company includes its share of earnings and losses of such investments in "Other (income) charges, net" located in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings.
For additional information, see Note 6, "Equity Investments".
Derivative and Non-Derivative Financial Instruments
Derivative and Non-Derivative Financial Instruments

Eastman uses derivative and non-derivative instruments to manage its exposure to market risks, such as changes in foreign currency exchange rates, commodity prices, and interest rates. The Company does not enter into derivative transactions for speculative purposes.

The Company's derivative instruments are recognized as either assets or liabilities on the Consolidated Statements of Financial Position and measured at fair value. Hedge accounting will be discontinued prospectively for all hedges that no longer qualify for hedge accounting treatment.

For additional information, see Note 10, "Derivative and Non-Derivative Financial Instruments".
Litigation and Contingent Liabilities
Litigation and Contingent Liabilities

From time to time, Eastman and its operations are parties to or targets of lawsuits, claims, investigations and proceedings, including product liability, personal injury, asbestos, patent and intellectual property, commercial, contract, environmental, antitrust, health and safety, and employment matters, which are handled and defended in the ordinary course of business. The Company accrues a contingent loss liability for such matters when it is probable that a liability has been incurred and the amount can be reasonably estimated. When a single amount cannot be reasonably estimated but the cost can be estimated within a range, the Company accrues the minimum amount. The Company expenses legal costs, including those expected to be incurred in connection with a loss contingency, as incurred.

For additional information, see Note 14, "Legal Matters".
Off-Balance-Sheet Credit Exposure, Policy [Policy Text Block]
Working Capital Management and Off-Balance Sheet Arrangements

The Company engages in off-balance sheet, uncommitted accounts receivable factoring programs as a routine part of its ordinary business operations. Through these programs, entire invoices may be sold to third-party financial institutions, the vast majority of which are without recourse. Under these agreements, the Company sells the invoices at face value, less a transaction fee, which substantially equals the carrying value and fair value with no gain or loss recognized, and no credit loss exposure is retained. Available capacity under these programs, which the Company uses as a routine source of working capital funding, is dependent on the level of accounts receivable eligible to be sold and the financial institutions' willingness to purchase such receivables. In addition, certain programs also require that the Company continue to service, administer, and collect the sold accounts receivable at market rates. The total amount of receivables sold in 2025 and 2024 were $2.7 billion and $2.7 billion, respectively.

The Company works with suppliers to optimize payment terms and conditions on accounts payable to enhance the timing of working capital and cash flows. As part of its supplier financing programs, suppliers may voluntarily sell receivables due from Eastman to a participating financial institution. Eastman's responsibility is limited to making payments on the terms originally negotiated with suppliers, and the range of payment terms Eastman negotiates with suppliers is consistent regardless of whether a supplier participates in the program. Either Eastman or a participating financial institution may terminate a supplier finance program upon 90 days' notice. Within these programs, the Company maintains a structured payables program that utilizes a payables processing arrangement with a financial institution to support the processing and settlement of freight and logistics invoices, whereby the financial institution remits payments to certain freight service providers based on invoices approved by the Company, and the Company reimburses the financial institution. There are no fees for participation in these programs; however, the Company pays fixed per‑transaction fees for the invoice processing and payment services for the structured payables program.

Confirmed obligations in these programs of $110 million and $56 million at December 31, 2025 and 2024, respectively, are included in "Payables and other current liabilities" on the Consolidated Statements of Financial Position. The following table presents a rollforward of obligations confirmed as valid through these programs for the year ended December 31, 2025:

Government Assistance
Government Grants

In the absence of explicit GAAP guidance on contributions received from government agencies, the Company applied by analogy the recognition and measurement guidance under IAS 20. The Company recognizes grants once it is probable that both of the following conditions will be met: (1) the Company is eligible to receive the grant, and (2) the Company is able to comply with the relevant conditions of the grant. Government grants whose primary condition is the purchase, construction, or acquisition of a long-lived asset are considered asset-based grants and are recognized as a reduction to such asset's cost basis, which reduces future depreciation expense. Proceeds received from asset-based grants are presented as cash inflows from investing activities on the Consolidated Statements of Cash Flows.

In 2024, the Company entered into a Cooperative Agreement ("the DOE grant") with the United States Department of Energy's ("DOE") Office of Clean Energy Demonstrations ("OCED") whereby certain costs incurred by the Company are reimbursed by the DOE. During the year ended December 31, 2024, pursuant to the DOE grant, the Company requested $11 million in reimbursements from the DOE, of which $9 million was received by the Company during 2024. The funds received reduced the carrying amount of certain fixed assets associated with the Company's Polyethylene Terephthalate Recycling Decarbonization Project in Longview, Texas (the "Project"), which were included in properties and equipment at December 31, 2024. The reduced carrying amount of the impacted assets is recognized in profit or loss over the life of the depreciable assets through reduced depreciation expense.

On May 29, 2025, the DOE terminated an award related to the Project. The Company continues to record reimbursements for amounts incurred prior to the date of the award termination and for which the Company is contractually entitled to under an assistance agreement with the DOE. The Company requested $21 million in reimbursements related to activity prior to the date of the award termination and has received $21 million in reimbursements from the DOE during the year. While waiting for a decision on reinstatement of the award, the Company is actively evaluating the impact of the termination on the project’s scope, timeline, and carrying values of associated assets. The Company has prepared a settlement proposal in the event reinstatement is not obtained.

(2)Public Equity - United States: Common stock equity securities which are primarily valued using a market approach based on the quoted market prices.
(3)Other Investments: Primarily consist of insurance contracts which are generally valued using a crediting rate that approximates market returns and investments in underlying securities whose market values are unobservable and determined using pricing models, discounted cash flow methodologies, or similar techniques.
(4)Investments Measured at Net Asset Value: The underlying debt, public equity, and public real asset investments in this category are generally held in common trust funds, which are either actively or passively managed investment vehicles, that are valued at the net asset value per unit/share multiplied by the number of units/shares held as of the measurement date. The other alternative investments in this category are valued under the practical expedient method which is based on the most recently reported net asset value provided by the management of each private investment fund, adjusted as appropriate, for any lag between the date of the financial reports and the measurement date.

The Company has operating leases, primarily leases for railcars, with terms that require the Company to guarantee a portion of the residual value of the leased assets upon termination of the lease that will expire beginning first quarter 2026. Residual guarantee payments that become probable and estimable are recognized as rent expense over the remaining life of the applicable lease. Management's current expectation is that the likelihood of material residual guarantee payments is remote.
