(a) See “Information Related to Financial Measures” for a discussion of the company’s use of non-GAAP financial measures and Tables 2-8 for reconciliations or calculations of these financial measures. “Identified items” include adjustments for lower of cost or market (“LCM”), impairments and refinery exit costs.

LyondellBasell Industries (NYSE: LYB) today announced net income for the second quarter 2023 of $715 million, or $2.18 per diluted share. During the quarter, the company recognized identified items of $86 million, net of tax. These items, which impacted second quarter earnings by $0.26 per share, were related to costs incurred from plans to exit the refining business. Second quarter 2023 EBITDA was $1.4 billion, or $1.5 billion excluding identified items.

Global olefins and polyolefins margins improved modestly during the second quarter driven by lower feedstock costs in both the U.S. and Europe. New capacity from the start of LyondellBasell's propylene oxide and oxyfuels plant in Texas was largely offset by planned maintenance at the company's existing assets. Oxyfuels margins remained strong, supported by low butane costs and robust demand for fuels. Refining margins declined from first quarter 2023 highs but remained above long-term averages.

LyondellBasell generated $1.3 billion in cash from operating activities in the second quarter and achieved 103% cash conversion(b) over the past twelve months. Available liquidity was $6.6 billion at the end of the quarter. The company remains committed to a disciplined approach to capital allocation. Approximately $300 million was reinvested in the business and $508 million was returned to shareholders through dividends and share repurchases. During the second quarter, LyondellBasell issued its inaugural green bond for $500 million to support investments advancing the company's strategy for leadership in sustainability.

LyondellBasell moved forward on the new strategy revealed at its Capital Markets Day in March. The company's Value Enhancement Program is progressing ahead of schedule. As a result, the program's near-term target was increased by approximately 30% and is now expected to deliver $150 million of net income(c) and $200 million of recurring annual EBITDA(c) by year end 2023. In May, LyondellBasell announced the decision to extend refining operations to no later than the end of the first quarter of 2025, as the company develops options to redeploy the site's workforce and assets in support of the company's sustainable growth strategy. LyondellBasell announced additional acquisitions and partnerships during the quarter toward building a profitable and leading Circular & Low Carbon Solutions business. In June, MSCI recognized the company's progress and upgraded LyondellBasell's ESG rating to 'AA', placing the company within the top 10% of companies in the sector.

“Our new strategy is driving focus and purpose across the company. LyondellBasell's employees are enthusiastically implementing our new strategy. We are committed to becoming the leader in fulfilling the rapidly increasing demand for sustainable solutions from our customers and society,” said Peter Vanacker, LyondellBasell Chief Executive Officer.

In the third quarter, the company expects typical benefits from summer seasonality to be more than offset by soft demand due to ongoing economic uncertainty. Stagnant demand, volatile feedstock costs and new capacity in North America and China are challenging petrochemical margins. Summer demand for transportation fuels continues to support attractive oxyfuels and refining margins. During the third quarter, LyondellBasell expects average operating rates of 85% for North American olefins and polyolefins (O&P) assets and 75% for European O&P as well as Intermediates & Derivatives assets in line with global market demand. The company believes current market conditions will persist amidst challenging economic conditions and a slower than expected recovery in China.

“LyondellBasell is steadfast in our resolve to advance on the three pillars of our long-term strategy despite near-term macro challenges. Our rapid progress is laying the necessary groundwork to extend our leadership in Circular & Low Carbon Solutions. I am pleased to see our Value Enhancement Program being embraced by our entire organization and driving sustainable value for our shareholders,” said Vanacker.

(b) Cash conversion is net cash provided by operating activities divided by EBITDA excluding LCM and impairment.

(c) Estimated based on 2017-2019 mid-cycle margins and modest inflation relative to a 2021 baseline.

There is no assurance that any of the actions, events or results of the forward-looking statements will occur, or if any of them do, what impact they will have on our results of operations or financial condition. Forward-looking statements speak only as of the date they were made and are based on the estimates and opinions of management of LyondellBasell at the time the statements are made.

LyondellBasell does not assume any obligation to update forward-looking statements should circumstances or management’s estimates or opinions change, except as required by law.

This release contains time sensitive information that is accurate only as of the date hereof. Information contained in this release is unaudited and is subject to change.

We undertake no obligation to update the information presented herein except as required by law.

This release makes 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, and EBITDA, net income and diluted EPS 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 income from continuing operations plus interest expense (net), provision for (benefit from) income taxes, and depreciation and amortization. EBITDA should not be considered an alternative to profit or operating profit for any period as an indicator of our performance, or as an alternative to operating cash flows as a measure of our liquidity. We also present EBITDA, net income and diluted EPS exclusive of identified items. Identified items include adjustments for “lower of cost or market" (“LCM”), impairment and refinery exit costs. 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. Property, plant and equipment are recorded at historical costs. 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. In April 2022 we announced our decision to cease operation of our Houston Refinery. In connection with exiting the refinery business, we began to incur costs primarily consisting of accelerated lease amortization costs, personnel related costs, accretion of asset retirement obligations and depreciation of asset retirement costs.

Recurring annual EBITDA for the Value Enhancement Program is estimated based on 2017-2019 mid-cycle margins and modest inflation relative to a 2021 baseline.

Cash conversion is a measure commonly used by investors to evaluate liquidity. For purposes of this presentation, cash conversion equals net cash provided by operating activities divided by EBITDA excluding LCM and impairment.

These non-GAAP financial measures as presented herein, may not be comparable to similarly titled measures reported by other companies due to differences in the way the measures are calculated. In addition, we include calculations for certain other financial measures to facilitate understanding. This release contains time sensitive information that is accurate only as of the time hereof. Information contained in this release is unaudited and subject to change.

LyondellBasell undertakes no obligation to update the information presented herein except to the extent required by law.

Additional operating and financial information may be found on our website at www.LyondellBasell.com/investorrelations. These measures as presented herein, may not be comparable to similarly titled measures reported by other companies due to differences in the way the measures are calculated.

LyondellBasell manages operations through six operating segments: 1) Olefins and Polyolefins-Americas; 2) Olefins and Polyolefins-Europe, Asia and International; 3) Intermediates and Derivatives; 4) Advanced Polymer Solutions; 5) Refining; and 6) Technology.

This information should be read in conjunction with our Earnings Release for the period ended June 30, 2023, including the forward-looking statements and information related to financial measures. Effective January 1, 2023, our Catalloy and polybutene-1 businesses, previously reported in our Advanced Polymer Solutions segment, will be reflected in our Olefins and Polyolefins-Americas and Olefins and Polyolefins-Europe, Asia and International segments.

Olefins & Polyolefins-Americas (O&P-Americas) - Our O&P-Americas segment produces and markets olefins & co-products, polyethylene, polypropylene, Catalloy and polybutene-1.

Three months ended June 30, 2023 versus three months ended March 31, 2023 - EBITDA increased $138 million versus the first quarter 2023. Compared to the prior period, olefins results increased approximately $15 million driven by higher volume absent of unplanned downtime. The company's ethylene crackers operated at 90% of capacity with the raw materials being 75% ethane and 20% other natural gas liquids. Combined polyolefins results increased approximately $100 million driven by higher margins due to lower feedstock costs.

Three months ended June 30, 2023 versus three months ended June 30, 2022 - EBITDA decreased $275 million versus the second quarter 2022. Olefins results decreased approximately $25 million driven by lower margins. Combined polyolefin results decreased approximately $305 million due to lower polyolefins margins driven by declining product prices as a result of soft demand and new industry capacity.

Olefins & Polyolefins-Europe, Asia, International (O&P-EAI) - Our O&P-EAI segment produces and markets olefins & co-products, polyethylene, polypropylene, Catalloy and polybutene-1.

Three months ended June 30, 2023 versus three months ended March 31, 2023 - EBITDA increased $7 million versus the first quarter 2023. Compared to the prior period, olefins results increased approximately $70 million due to improved cracker margins driven by lower feedstock and energy costs. The company's ethylene crackers operated at 85% of capacity with approximately 35% of the raw materials derived from non-naphtha feedstocks. Combined polyolefins results decreased $40 million compared to the prior period due to lower polyolefins margins as European markets remain challenging, especially for durable goods. Joint venture equity income decreased approximately $20 million primarily due to the absence of a gain on sale of asset recognized by one of our joint ventures in Europe in the first quarter of 2023.

Three months ended June 30, 2023 versus three months ended June 30, 2022 - EBITDA decreased $102 million versus the second quarter 2022 or $171 million, excluding an impairment of $69 million in the second quarter 2022 related to the exit of our Australia polypropylene business. Compared to the prior period, olefins results increased approximately $20 million driven by higher volumes in the absence of planned maintenance. Combined polyolefins results decreased $180 million due to margin compression driven by lower product pricing reflecting a weak demand.

Intermediates & Derivatives (I&D) - Our I&D segment produces and markets Propylene Oxide & Derivatives, Oxyfuels & Related Products and Intermediate Chemicals, such as styrene monomer, acetyls, ethylene oxide and ethylene glycol.

Three months ended June 30, 2023 versus three months ended March 31, 2023 - EBITDA increased $46 million compared to the first quarter 2023. Compared to the prior period, results for our Propylene Oxide & Derivatives decreased approximately $50 million due to weak demand. Oxyfuels & Related Products results increased approximately $100 million due to higher volumes driven by strong demand, partially offset by lower margins.

Three months ended June 30, 2023 versus three months ended June 30, 2022 - EBITDA decreased $203 million versus the second quarter 2022. Compared to the prior period, Propylene Oxide & Derivatives results decreased approximately $135 million due to lower demand pressuring margins. Intermediate Chemicals results decreased about $120 million driven by lower styrene prices due to well-supplied markets. Oxyfuels & Related Products decreased approximately $25 million due to lower margins, partially offset by higher volumes supported by strong demand.

Advanced Polymer Solutions (APS) - Our Advanced Polymer Solutions segment produces and markets Compounding & Solutions, such as polypropylene compounds, engineered plastics, masterbatches, engineered composites, colors and powders.

Three months ended June 30, 2023 versus three months ended March 31, 2023 - Relative to the first quarter 2023, EBITDA increased $260 million, or increased $8 million excluding a non-cash goodwill impairment of $252

million. Compared with the prior period, Compounding & Solutions results increased approximately $10 million due to moderately higher margins driven by improved polypropylene compounds prices.

Three months ended June 30, 2023 versus three months ended June 30, 2022 - Relative to the second quarter 2022, EBITDA decreased $8 million driven by lower Compounding & Solutions volumes reflecting a weak demand.

Refining - Our Refining segment produces and markets gasoline and distillates, including diesel fuel, heating oil and jet fuel.

Three months ended June 30, 2023 versus three months ended March 31, 2023 - Relative to the first quarter 2023, EBITDA decreased $199 million, or $201 million excluding exit costs. Refinery exit costs were $67 million in the second quarter 2023 and $69 million in the first quarter 2023. Compared to the prior period, refining margins decreased as the Maya 2-1-1 industry crack spread declined approximately $9 per barrel to $39 per barrel in the second quarter with heavy crude supply tightening leading to lower Maya and WCS crude discounts. The Houston Refinery operated at an average crude throughput of 245,000 barrels per day or about 91% utilization rate.

Three months ended June 30, 2023 versus three months ended June 30, 2022 - Relative to the second quarter 2022, EBITDA decreased $371 million, or $304 million, excluding exit costs of $67 million in the second quarter of 2023. Compared to the prior period, margins decreased with the Maya 2-1-1 industry crack spread decreasing approximately $16 per barrel due to lower demand and lower by-product margins. Crude throughput decreased by approximately 7,000 barrels per day.

Technology - Our Technology segment develops and licenses chemical and polyolefin process technologies and manufactures and sells polyolefin catalysts.

Three months ended June 30, 2023 versus three months ended March 31, 2023 - EBITDA increased $6 million compared to the prior period with higher licensing revenue, partially offset by lower catalyst volume and margin.

Three months ended June 30, 2023 versus three months ended June 30, 2022 - EBITDA decreased $33 million relative to the second quarter 2022. Compared to the prior period, licensing revenue decreased as a lower number of contracts attained revenue milestones. Catalyst volume decreased driven by reduced polymers demand.

Capital expenditures, including growth projects, maintenance turnarounds, catalyst and information technology-related expenditures, were $301 million during the second quarter 2023. Our cash and liquid investment balance was $2.5 billion, which includes cash and cash equivalents, restricted cash and short-term investments. There were 325 million common shares outstanding as of June 30, 2023. The company paid dividends of $408 million and repurchased approximately 1.1 million shares during the second quarter 2023.
