(a) See “Information Related to Financial Measures” for a discussion of the company’s use of non-GAAP financial measures and Table 6 for reconciliations of these financial measures. “Identified items” include adjustments for lower of cost or market (“LCM”), gain or loss on sale of business, asset write-downs in excess of $10 million in aggregate for the period, Cash Improvement Plan costs, site closure costs, European transaction costs and discontinued operations.

Three months ended December 31, 2025 versus three months ended September 30, 2025 - EBITDA decreased $256 million, or $264 million excluding identified items versus the third quarter 2025. Fourth quarter 2025 results decreased by approximately $35 million, reflecting the combined impact of last-in, first out (LIFO) inventory valuation and annual compensation accrual changes relative to the third quarter 2025. Compared to the prior period, olefins results decreased by approximately $170 million largely due to lower margins in the fourth quarter due to higher feedstock and energy costs coupled with lower ethylene and propylene prices. The company's ethylene crackers operated at 90% of capacity with the raw materials being approximately 75% ethane and 25% other natural gas liquids. Combined polyolefins results decreased approximately $65 million from lower volumes driven by reliability constraints and pressured domestic demand coupled with lower margins due to decreased spreads.

Three months ended December 31, 2025 versus three months ended December 31, 2024 - EBITDA decreased $334 million, or $332 million excluding identified items versus the fourth quarter 2024. Olefins results decreased approximately $250 million primarily driven by lower margins. Ethylene margins decreased due to higher feedstock and energy costs coupled with lower ethylene and propylene prices. Combined polyolefin results decreased approximately $100 million due to lower polyolefins margins and volumes, driven by lower product pricing amid challenging macroeconomic conditions coupled with decreased demand on oversupply.

INFORMATION RELATED TO FINANCIAL MEASURES
We make reference to certain non-GAAP financial measures as defined in Regulation G of the U.S. Securities Exchange Act of 1934, as amended.

We report our financial results in accordance with U.S. generally accepted accounting principles, but believe that certain non-GAAP financial measures, such as EBITDA exclusive of identified items provide useful supplemental information to investors regarding the underlying business trends and performance of the company's ongoing operations and are useful for period-over-period comparisons of such operations. Non-GAAP financial measures should be considered as a supplement to, and not as a substitute for, or superior to, the financial measures prepared in accordance with GAAP.

We calculate EBITDA as net income (loss) plus interest expense (net), provision for (benefit from) income taxes, and depreciation and amortization. Identified items include adjustments for lower of cost or market (“LCM”), gain or loss on sale of business, asset write-downs in excess of $10 million in aggregate for the period, Cash Improvement Plan costs, site closure costs, European transaction costs and discontinued operations. Asset write-downs include impairments of goodwill, impairments of long-lived assets, a write-down of a related party loan receivable and a fourth quarter 2024 deferred tax valuation allowance for one of our Chinese joint ventures recognized in Income (loss) from equity investments. Our inventories are stated at the lower of cost or market. Cost is determined using the last-in, first-out (“LIFO”) inventory valuation methodology, which means that the most recently incurred costs are charged to cost of sales and inventories are valued at the earliest acquisition costs. Fluctuation in the prices of crude oil, natural gas and correlated products from period to period may result in the recognition of charges to adjust the value of inventory to the lower of cost or market in periods of falling prices and the reversal of those charges in subsequent interim periods, within the same fiscal year as the charge, as market prices recover. A gain or loss on sale of a business is calculated as the consideration received from the sale less its carrying value. We evaluate property, plant and equipment and definite-lived intangible assets whenever impairment indicators are present. If it is determined that an asset or asset group’s undiscounted future cash flows will not be sufficient to recover the carrying amount, an impairment charge is recognized to write the asset down to its estimated fair value. Goodwill is tested for impairment annually in the fourth quarter or whenever events or changes in circumstances indicate that the fair value of a reporting unit with goodwill is below its carrying amount. If it is determined that the carrying value of the reporting unit including goodwill exceeds its fair value, an impairment charge is recognized. We assess our equity investments for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment may not be recoverable. If the decline in value is considered to be other than temporary the investment is written down to its estimated fair value. Valuation allowances are provided against deferred tax assets when it is more likely than not that some portion or all of the deferred tax asset will not be realized. In June 2025, we announced plans to sell select olefins and polyolefins assets and the associated business in Europe, resulting in selling expenses, separation costs and employee-related charges (collectively referred to as "European transaction costs"). In April 2025, the company announced the Cash Improvement Plan, focused on strengthening financial performance, which resulted in employee-related charges across all segments. In March 2025, we announced the permanent closure of our Dutch PO joint venture asset, resulting in the recognition of shutdown-related charges in our I&D segment. Additionally, in December 2025, we recognized shutdown and employee-related charges related to sites in our APS and O&P-EAI segments. In February 2025, we ceased business operations at our Houston refinery. Accordingly, our refining business, previously disclosed as the Refining segment, is reported as a discontinued operation.
