LyondellBasell Industries (NYSE: LYB) today announced net income for the third quarter 2023 of $0.7 billion, or $2.29 per diluted share. During the quarter, the company recognized identified items of $57 million, net of tax, which impacted third quarter earnings by $0.17 per share. Third quarter 2023 EBITDA was $1.4 billion.

Exceptional oxyfuels margins contributed to a record Intermediates & Derivatives EBITDA of $708 million during the third quarter. Global olefins and polyolefins margins were compressed by higher feedstock costs, tepid polymer demand in both the U.S. and Europe, and new industry capacity. North American polyethylene export volumes increased as global trade flows continued to normalize toward pre-pandemic levels.

LyondellBasell generated $1.7 billion in cash from operating activities in the third quarter and achieved 102% cash conversion over the past twelve months. The company remains committed to its balanced and disciplined capital allocation framework and priorities. Third quarter cash from operating activities covered the repayment of maturing bonds, capital investments and the return of $448 million to shareholders through dividends and share repurchases. Cash and short-term investments increased by $350 million during the quarter. Available liquidity was $7 billion at the end of the quarter.

In September, LyondellBasell launched +LC (Low Carbon) solutions for select chemical products including propylene oxide, styrene and other products sourced from recycled and renewable-based feedstocks. The company is providing +LC solutions to meet the growing customer demand for sustainable materials that have a lower greenhouse gas (GHG) footprint relative to fossil-based alternatives. In addition, with a new solar power purchase agreement in Spain, the company has rapidly achieved 78% of its goal to procure half of its electricity from renewable sources by 2030.

“LyondellBasell is delivering resilient results and outstanding cash conversion amid challenging market conditions while remaining focused on the execution of our long-term strategy. The successful startup of our new propylene oxide and oxyfuels asset is aligned with our strategy to grow and upgrade our core businesses. Our oxyfuels business captured exceptionally strong oxyfuels margins that drove record quarterly results for our Intermediates and Derivatives segment,” said Peter Vanacker, LyondellBasell Chief Executive Officer.

In the fourth quarter, the company expects seasonally softer demand across most businesses. Higher feedstock costs, new industry capacity and the slow pace of Chinese demand growth continue to pressure global olefins and polyolefins margins. Oxyfuels and refining margins are expected to decrease following the conclusion of the summer driving season. Nonetheless, oxyfuels margins are expected to remain well above historical averages. During the fourth quarter, LyondellBasell expects to operate its assets in line with market demand with average operating rates of 85% for North American olefins and polyolefins (O&P) assets, 75% for European O&P assets and 70% for Intermediates & Derivatives assets.

“Implementation of LyondellBasell's long-term strategy remains our top priority. One year after launching our Value Enhancement Program, we are highly confident we will exceed our 2023 recurring annual EBITDA exit run-rate target of $200 million(c). The three pillars of our strategy reinforce each other. By stepping up our performance and culture with a pivot toward value creation, LyondellBasell will be able to grow and upgrade our core while building a profitable Circular and Low Carbon Solutions business. Looking ahead, we will continue to leverage our unique advantages to position LyondellBasell for a sustainable future,” said Vanacker.

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

Additional factors that could cause results to differ materially from those described in the forward-looking statements can be found in the “Risk Factors” section of our Form 10-K for the year ended December 31, 2022, which can be found at www.LyondellBasell.com on the Investor Relations page and on the Securities and Exchange Commission’s website at www.sec.gov. 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 means net cash provided by operating activities divided by EBITDA excluding LCM and impairment. We believe cash conversion is an important financial metric as it helps management and other parties determine how efficiently the company is converting earnings into cash.

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 September 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 and polypropylene.

Three months ended September 30, 2023 versus three months ended June 30, 2023 - EBITDA decreased $200 million versus the second quarter 2023 or $175 million, excluding an impairment of $25 million in the third quarter 2023 related to capital project costs. Compared to the prior period, olefins results decreased approximately $30 million driven by lower volume due to planned maintenance. The company's ethylene crackers operated at 85% of capacity with the raw materials being 70% ethane and 25% other natural gas liquids. Combined polyolefins results decreased approximately $115 million driven by lower integrated polyethylene margins due to higher feedstock costs and new industry capacity, partially offset by higher polyethylene export volumes.

Three months ended September 30, 2023 versus three months ended September 30, 2022 - EBITDA decreased $109 million versus the third quarter 2022 or $84 million, excluding an impairment of $25 million in the third quarter 2023. Olefins results increased approximately $135 million driven by higher margins due to lower energy and feedstock costs. Combined polyolefin results decreased approximately $220 million due to lower polyolefins margins driven by reduced 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 and polypropylene.

Three months ended September 30, 2023 versus three months ended June 30, 2023 - EBITDA decreased $129 million versus the second quarter 2023. Compared to the prior period, olefins results decreased approximately $75 million due to lower cracker margins driven by weak demand and higher naphtha costs. The company's ethylene crackers operated at approximately 80% of capacity with about 45% of the raw materials derived from non-naphtha feedstocks. Combined polyolefins results decreased approximately $60 million compared to the prior period due to lower polyolefins margins as European markets remain challenging.

Three months ended September 30, 2023 versus three months ended September 30, 2022 - EBITDA increased $29 million versus the third quarter 2022. Compared to the prior period, olefins results increased approximately $25 million driven by higher volumes in the absence of planned and unplanned maintenance. Combined polyolefins results decreased $30 million due to margin compression in polyethylene driven by lower product pricing reflecting a weak demand. Joint venture equity income increased approximately $35 million due to higher margins at our Asia and Middle East joint ventures.

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 September 30, 2023 versus three months ended June 30, 2023 - EBITDA increased $236 million to a record quarter EBITDA of $708 million compared to the second quarter 2023. Compared to the prior period, results for our Propylene Oxide & Derivatives increased approximately $20 million due to higher export volumes to Asia. Oxyfuels & Related Products results increased approximately $235 million due to exceptional oxyfuels margins driven by industry downtime.

Three months ended September 30, 2023 versus three months ended September 30, 2022 - EBITDA increased $348 million versus the third quarter 2022. Compared to the prior period, Propylene Oxide & Derivatives results decreased approximately $65 million due to lower demand for durable goods pressuring margins, partially offset by higher propylene oxide exports to Asia. Intermediate Chemicals results increased $75 million driven by higher styrene margins due to lower feedstock costs. Oxyfuels & Related Products increased approximately $310 million due to record margins driven by strong demand for gasoline and additional capacity.

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 September 30, 2023 versus three months ended June 30, 2023 - Compared to the second quarter 2023, EBITDA decreased $16 million driven by lower Compounding & Solutions margins and volumes due to product sales mix and reduced demand.

Three months ended September 30, 2023 versus three months ended September 30, 2022 - Compared to the third quarter 2022, EBITDA decreased $10 million driven by lower Compounding & Solutions volumes reflecting a soft demand.

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

Three months ended September 30, 2023 versus three months ended June 30, 2023 - Relative to the second quarter 2023, EBITDA increased $29 million, or decreased $9 million, excluding exit costs. Compared to the prior period, improvement in refining margins driven by a slightly higher Maya 2-1-1 industry crack spread was more than offset by hedging impact. The Houston Refinery operated at an average crude throughput of 248,000 barrels per day or about 93% utilization rate.

Three months ended September 30, 2023 versus three months ended September 30, 2022 - Relative to the third quarter 2022, EBITDA decreased $30 million, or $85 million, excluding exit costs. Compared to the prior period, margins decreased with the Maya 2-1-1 industry crack spread decreasing approximately $6 per barrel due to tightened crude supply and lower distillate demand. Crude throughput increased by approximately 32,000 barrels per day absent of planned maintenance.

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

Three months ended September 30, 2023 versus three months ended June 30, 2023 - EBITDA increased $67 million compared to the prior period driven by higher licensing revenue due to contract revenue milestones and improved catalyst results.

Three months ended September 30, 2023 versus three months ended September 30, 2022 - EBITDA increased $54 million relative to the third quarter 2022. Compared to the prior period, licensing revenue increased due to contract revenue milestones. Catalyst margins increased driven by product mix and lower energy costs.

Capital expenditures, including growth projects, maintenance turnarounds, catalyst and information technology-related expenditures, were $394 million during the third quarter 2023.
