In the opinion of management, all adjustments, including normal recurring adjustments, considered necessary for a fair statement have been included.

The results for interim periods are not necessarily indicative of results for the entire year.

Recently Adopted Guidance
There were no new standards or Accounting Standard Updates (“ASU”) adopted in the six months ended June 30, 2025, that had a material impact on the Consolidated Financial Statements.
Accounting Guidance Issued But Not Adopted as of June 30, 2025
Expense Disaggregation Disclosures—In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This guidance requires incremental disclosures about specific expense categories, including but not limited to, purchases of inventory, employee compensation, depreciation, amortization and selling expenses. The amendments are effective for fiscal years beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027. While permitted, we do not plan to early adopt this guidance. The guidance may be applied either prospectively or retrospectively. The adoption of this ASU will not have a material impact on our Consolidated Financial Statements as the guidance relates only to disclosure.
Income Tax Disclosures—In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The guidance requires companies to disclose certain specific categories in the rate reconciliation and provide additional information for reconciling items that meet the quantitative threshold of 5% of the expected tax using the applicable statutory income tax rate. There is also a required disclosure to provide the net income taxes paid or received disaggregated by federal, state, and foreign taxes with jurisdictions to be separately disclosed if the jurisdiction is 5% or more of the total net income taxes paid or received. The guidance is effective for annual periods beginning after December 15, 2024. We will adopt the new guidance for our Income Tax Disclosures in the 2025 annual period. The adoption of this ASU will not have a material impact on our Consolidated Financial Statements as the guidance relates only to disclosure.

Assets Held For Sale [Abstract]  
Assets Held for Sale Assets Held for Sale
Proposed European Asset Sale—In June 2025, we entered into an agreement for the sale of select olefins & polyolefins assets and the associated business in Europe. The sites to be sold have been part of the previously announced European strategic assessment and are located in Berre l’Etang (France), Münchsmünster (Germany), Carrington (United Kingdom), and Tarragona (Spain). The sites identified for sale are within our Olefins & Polyolefins-Europe, Asia, International (“O&P-EAI”) segment. The agreement is a put option deed under which the purchaser has committed to enter into an agreed form purchase agreement if we exercise our put option, after conclusion of certain works council consultation processes.
Closing of the proposed transaction is currently expected in the first half of 2026, subject to the completion of the information and consultation processes with the relevant employee representative bodies in accordance with applicable laws, as well as regulatory and other customary closing conditions. The assets and liabilities associated with the business to be sold have been classified as held for sale in the Consolidated Balance Sheets as of June 30, 2025.
In connection with the sale, we expect to recognize a loss on sale of approximately $700 million to $900 million upon closing. The loss principally consists of the transfer of net working capital of approximately $340 million, a cash contribution of $300 million to the sold businesses prior to closing, a foreign currency translation adjustment of approximately $300 million to $400 million, and a net equity method investment of approximately $10 million, partially offset by the transfer of pension and other liabilities of $150 million to $250 million.
Other costs, including selling expenses, separation costs, and employee-related costs, of approximately $100 million to $150 million, are estimated to be incurred prior to closing. During the second quarter of 2025, we incurred $10 million of such costs in connection with this transaction.
During the second quarter of 2025, a non-cash impairment loss of $32 million was recognized and allocated to property, plant and equipment. The fair value of the disposal group was determined based on the expected consideration and other fair value indicators obtained through our marketing efforts and classified as Level 2 within the fair value hierarchy. The impairment charge is presented within Impairments in the Consolidated Statements of Income.
U.S. Specialty Powders Business—In the second quarter of 2025, we entered into an agreement to sell our U.S. specialty powders business for a total consideration of approximately $10 million, subject to working capital and other adjustments. The transaction is expected to close in the second half of 2025 and is subject to customary closing conditions. The business had been identified as a non-core business within our Advanced Polymer Solutions (“APS”) segment.

Long-Term Debt
Senior Revolving Credit Facility—Our $3,750 million senior unsecured revolving credit facility (the “Senior Revolving Credit Facility”), which expires in July 2029, may be used for dollar and euro denominated borrowings. The facility also supports our commercial paper program, has a $200 million sub-limit for dollar and euro denominated letters of credit and a $1,000 million uncommitted accordion feature. Borrowings under the facility bear interest at either a base rate, secured overnight financing rate or EURIBOR rate, plus an applicable margin. Additional fees are incurred for the average daily unused commitments. As of June 30, 2025, we had no borrowings or letters of credit outstanding and $3,750 million of unused availability under this facility.
Guaranteed Notes due 2035—In May 2025, LYB International Finance III, LLC (“LYB Finance III”), a wholly owned finance subsidiary of LyondellBasell Industries N.V., issued $500 million of 6.150% guaranteed notes due 2035 (the “2035 Notes”) at a discounted price of 99.7%. Net proceeds after deducting original issuance discounts, underwriting fees and offering expenses totaled $494 million. Net proceeds from the sale of the notes are used for general corporate purposes, including the repayment of our 2025 Notes.
These unsecured notes, which are fully and unconditionally guaranteed by LyondellBasell Industries N.V., rank equally in right of payment to all of LYB Finance III’s and LyondellBasell Industries N.V.’s existing and future senior unsecured indebtedness and will rank senior in right of payment to any future subordinated indebtedness that LYB Finance III or LyondellBasell Industries N.V. incurs. There are no significant restrictions that would impede LyondellBasell Industries N.V., as guarantor, from obtaining funds by dividend or loan from its subsidiaries. The indenture governing these notes contains limited covenants, including those restricting our ability, and the ability of our subsidiaries, to incur indebtedness secured by significant property or by capital stock of subsidiaries that own significant property, enter into certain sale and lease-back transactions with respect to any significant property or enter into consolidations, mergers or sales of all or substantially all of our assets.
The 2035 Notes may be redeemed at any time in whole, or from time to time in part, prior to the scheduled maturity date, at a redemption price equal to the greater of (i) the sum of the present values of the remaining scheduled payments of principal and interest (discounted at the treasury rate plus the applicable basis points) less interest accrued on the notes to be redeemed, and (ii) 100% of the principal amount of the notes redeemed; plus, in either case, accrued and unpaid interest thereon to, but excluding, the redemption date. The 2035 Notes may also be redeemed at any time, on or after the date that is three months prior to the scheduled maturity date of the notes at a redemption price equal to 100% of the principal amount of the notes to be redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date. The notes are also redeemable upon certain tax events.
Short-Term Debt
U.S. Receivables Facility—Our U.S. Receivables Facility has a purchase limit of $900 million in addition to a $300 million uncommitted accordion feature. In May 2025, we extended the term of the facility to June 2026. This facility provides liquidity through the sale or contribution of trade receivables by certain of our U.S. subsidiaries to a wholly owned, bankruptcy-remote subsidiary on an ongoing basis and without recourse. We pay variable interest rates on our secured borrowings. Additional fees are incurred for the average daily unused commitments. This facility also provides for the issuance of letters of credit up to $200 million. As of June 30, 2025, we had no borrowings or letters of credit outstanding and $900 million unused availability under this facility.
Commercial Paper Program—We have a commercial paper program under which we may issue up to $2,500 million of privately placed, unsecured, short-term promissory notes (“commercial paper”). As of June 30, 2025, we had no borrowings of outstanding commercial paper.
Precious Metal Financings—At both June 30, 2025 and December 31, 2024, we had $119 million of Short-term debt related to our precious metal financings.
Weighted Average Interest Rate—As of June 30, 2025 and December 31, 2024, our weighted average interest rates on outstanding Short-term debt were 1.6% and 1.1%, respectively.

Debt Compliance—As of June 30, 2025, we are in compliance with our debt covenants.

Income Taxes

Income Tax Disclosure [Abstract]  
Income Taxes Income Taxes
For interim tax reporting, we estimate an annual effective tax rate which is applied to the year-to-date ordinary income. Tax effects of significant, unusual, or infrequently occurring items are excluded from the estimated annual effective tax rate calculation and recognized in the interim period in which they occur. Our effective income tax rate fluctuates based on, among other factors, changes in pre-tax income in countries with varying statutory tax rates, changes in valuation allowances, changes in foreign exchange gains or losses, the amount of exempt income, changes in unrecognized tax benefits associated with uncertain tax positions and changes in tax laws.
Our exempt income primarily includes interest income, export incentives, and equity earnings of joint ventures. Interest income earned by certain of our subsidiaries through intercompany financings is taxed at rates substantially lower than the U.S. statutory rate. Export incentives relate to tax benefits derived from elections and structures available for U.S. exports. Equity earnings attributable to the earnings of our joint ventures, when paid through dividends to certain European subsidiaries, are exempt from all or portions of normal statutory income tax rates. We currently anticipate the favorable treatment for interest income, dividends, and export incentives to continue in the current year based on current law. The United Kingdom, as well as certain other jurisdictions in which we operate, enacted legislation implementing the Organization for Economic Cooperation and Development’s Pillar Two Model Rules effective as of January 1, 2024. This legislation did not have a material impact on the Consolidated Financial Statements, however, we continue to assess and monitor legislative changes.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted into law. OBBBA includes tax reform extending and modifying certain key Tax Cuts & Jobs Act provisions such as accelerated tax deductions for qualified property and domestic research expenditures, and modifications to the limitations on deductions for interest expense. The provisions of the OBBBA have different effective dates where some are effective in 2025 and others not until 2026. This legislation is not expected to have a material impact on the Consolidated Financial Statements; however, we continue to assess the impact.
Our effective income tax rate for the second quarter of 2025 was 30.8% compared to 21.1% for the second quarter of 2024. The higher effective tax rate for the second quarter of 2025 was primarily due to the discrete tax recognition of foreign exchange gains and losses with lower pre-tax earnings that increased our effective income tax rate by 26.9 percentage points. This increase to the effective tax rate was partially offset by the increased relative impact of our tax rate drivers, primarily exempt income and fluctuations in return to accruals, due to lower earnings that decreased our effective income tax rate by 15.3 percentage points.
Our effective income tax rate for the first six months of 2025 was 37.1% compared to 20.8% for the first six months of 2024. The higher effective tax rate for the first six months of 2025 was primarily due to the discrete tax recognition of foreign exchange gains and losses with lower pre-tax earnings that increased our effective tax rate by 32.2 percentage points. This increase to the effective tax rate was partially offset by the increased relative impact of our tax rate drivers, primarily exempt income, due to decreased earnings that decreased our effective income tax rate by 11.9 percentage points.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]  
Commitments and Contingencies Commitments and Contingencies
Commitments—We have various purchase commitments for materials, supplies and services incidental to the ordinary conduct of business, generally for quantities required for our businesses and at prevailing market prices. These commitments are designed to ensure sources of supply and are not expected to be in excess of normal requirements. Additionally, we have capital expenditure commitments, which we incur in our normal course of business.
Financial Assurance Instruments—We have obtained letters of credit, performance and surety bonds and have issued financial and performance guarantees to support trade payables, potential liabilities and other obligations. Considering the frequency of claims made against the financial instruments we use to support our obligations, and the magnitude of those financial instruments in light of our current financial position, management does not expect that any claims against or draws on these instruments would have a material adverse effect on the Consolidated Financial Statements. We have not experienced any unmanageable difficulties in obtaining the required financial assurance instruments for our current operations.
Environmental Remediation—Accrued liabilities for future environmental remediation costs at current and former plant sites and other remediation sites totaled $101 million and $140 million as of June 30, 2025 and December 31, 2024, respectively. As of June 30, 2025, the accrued liabilities for individual sites range from less than $1 million to $41 million. The remediation expenditures are expected to occur over a number of years and are not concentrated in any single year. In our opinion, it is reasonably possible that losses in excess of the liabilities recorded may have been incurred. However, we cannot estimate any amount or range of such possible additional losses. New information about sites, new technology or future developments, such as involvement in investigations by regulatory agencies, could require us to reassess our potential exposure related to environmental matters.
Indemnification—We are parties to various indemnification arrangements, including arrangements entered into in connection with acquisitions, divestitures and the formation and dissolution of joint ventures. Pursuant to these arrangements, we provide indemnification to and/or receive indemnification from other parties in connection with liabilities that may arise in connection with the transactions and in connection with activities prior to completion of the transactions. These indemnification arrangements typically include provisions pertaining to third-party claims relating to environmental and tax matters and various types of litigation. As of June 30, 2025, we had not accrued any significant amounts for our indemnification obligations, and we are not aware of other circumstances that would likely lead to significant future indemnification obligations. We cannot determine with certainty the potential amount of future payments under the indemnification arrangements until events arise that would trigger a liability under the arrangements.
As part of our technology licensing contracts, we give indemnifications to our licensees for liabilities arising from possible patent infringement claims with respect to certain proprietary licensed technologies. Such indemnifications have a stated maximum amount and generally cover a period of 5 to 10 years.
Legal Proceedings—We are subject to various lawsuits and claims, including but not limited to, matters involving contract disputes, tort claims, and regulatory disputes alleging environmental damages, personal injury and/or property damage, some of which are covered by insurance. We vigorously defend ourselves and prosecute these matters as appropriate.
Our legal organization applies its knowledge, experience and professional judgment to the specific characteristics of our cases, employing a litigation management process to manage and monitor legal proceedings in which we are a party. Our process facilitates the early evaluation and quantification of potential exposures in individual cases. This process also enables us to track those cases that have been scheduled for trial, mediation or other resolution. We regularly assess the adequacy of legal accruals based on our professional judgment, experience and the information available regarding our cases.
Based on consideration of all relevant facts and circumstances, we do not believe the ultimate outcome of any currently pending lawsuit or claim against us will have a material adverse effect upon our operations, financial condition or Consolidated Financial Statements.

Earnings Per Share [Abstract]  
Per Share Data Per Share Data
Basic earnings per share is based upon the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share includes the effect of certain stock options and other equity-based compensation awards. Our unvested restricted stock units contain non-forfeitable rights to dividend equivalents and are considered participating securities. We compute basic and diluted earnings per share under the two-class method.
Earnings per share data is as follows:

Segment Reporting [Abstract]  
Segment and Related Information Segment and Related Information
Our operations are managed by senior executives who report to our Chief Executive Officer, the chief operating decision maker. Discrete financial information is available for each of the segments. The Chief Executive Officer uses EBITDA as the primary measure for reviewing the profitability of our segments and allocating resources to the segments. We define EBITDA as net income before interest, income taxes, and depreciation and amortization. Our chief operating decision maker does not receive information about total assets by reportable segment.
The activities of each of our segments from which they earn revenues and incur expenses are described below: 
•Olefins and Polyolefins-Americas (“O&P-Americas”). Our O&P-Americas segment produces and markets olefins and co-products, polyethylene and polypropylene.
•Olefins and Polyolefins-Europe, Asia, International (“O&P-EAI”). Our O&P-EAI segment produces and markets olefins and co-products, polyethylene and polypropylene.
•Intermediates and Derivatives (“I&D”). Our I&D segment produces and markets propylene oxide and its derivatives; oxyfuels and related products; and intermediate chemicals such as styrene monomer and acetyls.
•Advanced Polymer Solutions (“APS”). Our APS segment produces and markets compounding and solutions, such as polypropylene compounds, engineered plastics, masterbatches, engineered composites, colors and powders.
•Technology. Our Technology segment develops and licenses chemical and polyolefin process technologies and manufactures and sells polyolefin catalysts.
“Other” includes intersegment eliminations and items that are not directly related or allocated to business operations, such as foreign exchange gains or losses and components of pension and other postretirement benefit costs other than service costs. Sales between segments are made at prices approximating prevailing market prices.
Summarized financial information concerning reportable segments is shown in the following tables for the periods presented:

Closure of European PO Joint Venture—In March 2025, we announced our plans to permanently close the Propylene Oxide Styrene Monomer (POSM) production unit at the Maasvlakte site in the Netherlands. The Maasvlakte site is a joint venture between us and Covestro (our “European PO Joint Venture”). The joint venture was formed solely for the benefit of the partners and does not manufacture for any other parties. We report the cost of our product off-take as Inventory and the equity loss as Cost of sales in our Consolidated Financial Statements.
As of December 31, 2024, the book value of the European PO Joint Venture was immaterial largely due to asset impairments recognized during 2023. We will carry out a process to safely shut down and prepare for the demolition of the asset. We estimate our portion of the total shutdown costs will be approximately $215 million and will be incurred through 2027. During the first quarter of 2025, we incurred $117 million of shutdown costs.
Disposition of Ethylene Oxide & Derivatives (“EO&D”) Business—In May 2024, we sold our U.S. Gulf Coast-based EO&D business along with the production facilities located in Bayport, TX. The EO&D business was included in our I&D segment. In connection with the sale, we received cash proceeds of $700 million and recognized a pre-tax gain of $293 million in the first six months of 2024.
Acquisition of Joint Venture—In May 2024, we acquired a 35% interest in Saudi Arabia-based National Petrochemical Industrial Company (“NATPET”) from Alujain Corporation for approximately $500 million. The joint venture is enabled by our Spheripol polypropylene (“PP”) technology and positions us to expand our core PP business by gaining access to advantaged feedstocks. The joint venture has the capacity to produce 0.4 million tons of PP per year. We market the majority of the off-take through our global sales team. The joint venture is included in our O&P-EAI segment and accounted for using the equity method of accounting.

Recently Adopted Guidance
There were no new standards or Accounting Standard Updates (“ASU”) adopted in the six months ended June 30, 2025, that had a material impact on the Consolidated Financial Statements.
Accounting Guidance Issued But Not Adopted as of June 30, 2025
Expense Disaggregation Disclosures—In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This guidance requires incremental disclosures about specific expense categories, including but not limited to, purchases of inventory, employee compensation, depreciation, amortization and selling expenses. The amendments are effective for fiscal years beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027. While permitted, we do not plan to early adopt this guidance. The guidance may be applied either prospectively or retrospectively. The adoption of this ASU will not have a material impact on our Consolidated Financial Statements as the guidance relates only to disclosure.
Income Tax Disclosures—In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The guidance requires companies to disclose certain specific categories in the rate reconciliation and provide additional information for reconciling items that meet the quantitative threshold of 5% of the expected tax using the applicable statutory income tax rate. There is also a required disclosure to provide the net income taxes paid or received disaggregated by federal, state, and foreign taxes with jurisdictions to be separately disclosed if the jurisdiction is 5% or more of the total net income taxes paid or received. The guidance is effective for annual periods beginning after December 15, 2024. We will adopt the new guidance for our Income Tax Disclosures in the 2025 annual period. The adoption of this ASU will not have a material impact on our Consolidated Financial Statements as the guidance relates only to disclosure.
