LyondellBasell Industries (LYB) Earnings: Q3 2026 Results and Next Report Date

The quarter ended September 30, 2026 and LyondellBasell published the results on October 30, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison. LyondellBasell reports EPS two ways: GAAP, under the accounting rules every US filer follows, and excluding identified items, which leaves out items the company considers outside its operating results. The release reconciles the two, and when they diverge, the reconciliation says why.

• Revenue is LyondellBasell's sales and other operating revenues. Its former Houston refinery, closed in February 2025, is reported as a discontinued operation.
• LyondellBasell completed the sale of select European olefins and polyolefins assets in May 2026, which lowered O&P-EAI volumes from Q3 2026 on.
• The year-ago quarter was a net loss of $890 million, after non-cash goodwill impairments of $400 million in O&P-EAI and $572 million in Advanced Polymer Solutions.

Segment lines are the figures writers cite most often, because they show where the growth in a quarter came from. Companies redraw their segments from time to time and restate the prior year to match, so a year-ago figure here can differ from the one printed a year ago. When that has happened, the note above says so.

From the earnings release

LyondellBasell gives operating rates and market conditions, not a revenue or EPS figure.

In its Q3 2026 release, LyondellBasell said:

“In the fourth quarter, we expect normal seasonal demand patterns along with ongoing supply uncertainty.”

“LYB expects fourth quarter operating rates of 85% for North American O&P assets, 60% for European O&P assets and 75% for Intermediates & Derivatives assets.”

“The fourth quarter is expected to deliver a seasonal release of working capital.”

This is the company's own guidance as of Oct 30, 2026, quoted as given. Walnut does not make forecasts of its own. Analyst estimates for the coming quarters are on the LYB forecast page.

Revenue and diluted EPS for the last 5 quarters. Each date links to that quarter's release.

Sales and other operating revenues and GAAP diluted earnings (loss) per share, each as first reported in that quarter's release.

LyondellBasell's next report is expected around January 29, 2027, a date estimated from its reporting history that the company has not yet confirmed. This page will show Q3 2026 until those results are out and have been checked against the release.

Each quarter keeps its own page with the figures as reported, so a link to one stays pointed at the same numbers after the next report.

• Q3 2026 (this page), reported Oct 30, 2026

LyondellBasell's sales and other operating revenues were $8,499 million in Q3 2026, against $7,727 million a year earlier and $9,177 million in Q2 2026. By product, polyethylene brought in $1,908 million, oxyfuels and related products $1,887 million, polypropylene $1,399 million, olefins and co-products $1,257 million and compounding and solutions $923 million. (LyondellBasell Form 10-Q, Q3 2026, Oct 30, 2026)

Against Q2 2026, revenue fell $678 million, or 7%. LyondellBasell says lower average sales prices cut revenue by 12%, higher volumes added 6% because its I&D segment had no repeat of Q2's unplanned outages, and foreign exchange took off 1%. In O&P-Americas, lower prices for polymers and olefin products reduced profitability; olefins results fell about $320 million and combined polyolefins about $265 million, with the ethylene crackers running at about 90% of capacity on a feed of about 75% ethane.

Oxyfuels and related products revenue rose to $1,887 million from $1,285 million a year earlier, and LyondellBasell says global supply disruptions raised crack spreads while gasoline blend economics lifted octane values. Utilization of the Channelview PO/TBA asset reached about 110% and Bayport PO/TBA ran at full rates after restarting in June. I&D EBITDA excluding identified items was $795 million, against $386 million in Q2.

United States customers accounted for $3,433 million of revenue, against $2,815 million a year earlier, followed by Germany ($559 million), Japan ($509 million), Mexico ($453 million) and China ($407 million). No single customer accounted for 10% or more of total revenues in 2025, 2024 or 2023. In O&P-EAI, volumes were lower after the May 2026 sale of European assets and the region's crackers ran at about 70% of capacity.

LyondellBasell reported diluted EPS of $2.32 in Q3 2026 and $2.54 excluding identified items, against a loss of $2.77 and $1.01 excluding identified items a year earlier. The Q3 2026 identified items were $70 million after tax, or $0.22 per share, mostly $0.17 of site closure costs for its European propylene oxide joint venture, whose shutdown cost about $76 million in the quarter.

The year-ago loss came from $1,202 million of pre-tax asset write-downs, or $3.51 per share, which included goodwill impairments of $400 million in O&P-EAI and $572 million in Advanced Polymer Solutions. The effective income tax rate was 19.4% in Q3 2026, against 3.2% a year earlier, when the impairments carried largely no tax benefit.

LyondellBasell's share count was flat at 323 million diluted shares, against 322 million a year earlier. It paid $224 million of dividends and did not repurchase shares in the quarter. (LyondellBasell Q3 2026 earnings release, Oct 30, 2026; LyondellBasell Q3 2026 business results by segment (Exhibit 99.2), Oct 30, 2026)

Diluted EPS divides net income by the weighted average number of shares outstanding in the quarter, plus the shares that options and other equity awards could add. Buybacks shrink that count and lift EPS for the same profit; share issuance and stock awards enlarge it.

LyondellBasell's outlook gives operating rates, not a revenue or EPS figure. For Q4 2026 it expects operating rates of 85% for North American O&P assets, 60% for European O&P assets and 75% for Intermediates & Derivatives assets, a planned maintenance project at a North American polypropylene asset, normal seasonal demand and a seasonal release of working capital. (LyondellBasell Q3 2026 earnings release, Oct 30, 2026)

LyondellBasell also says conditions in the Middle East are likely to remain fluid and a return to pre-conflict conditions is likely to take longer than anticipated, while polyethylene domestic and export demand is strong and oxyfuels margins and demand remain strong.

A consensus figure is the average of the models published by the analysts who cover LyondellBasell, collected by a data provider and revised up to the day of the report. A quarter that lands above it says how expectations were set as much as how the business did, and the share price on the day also reflects the guidance and the lines no consensus covers.

The consensus figures on this page are Yahoo Finance's, as pulled on the date shown. Each comes with the number of analysts behind it; the smaller that number, the more one revised estimate can move the average.

The figures below are the ones LyondellBasell's own release and filings put weight on for Q3 2026, with the latest reported value for each.

What the quarter means for a holding is a separate question from what it reported. The case for and against owning LYB is on is LYB a buy or a sell?, what analysts expect next is on the LYB forecast, and what the company does is on the LyondellBasell Industries (LYB) stock page.

Every number on this page can be traced to a document LyondellBasell published. Checking one takes a couple of minutes, and it is worth doing before you quote a figure anywhere.

• The results release is the document linked in the source line above. Companies publish it on their investor relations site at the moment results go out, and it carries the headline tables: revenue, operating income, net income and EPS for the quarter and the year-ago quarter.
• The same release is filed with the SEC as Exhibit 99.1 to a Form 8-K under Item 2.02, usually on the day of the report. The SEC copy does not change after the fact, which makes it the safer thing to link when you cite a number.
• The quarterly report (Form 10-Q) follows within a few weeks and carries the full financial statements, the segment note and management's discussion of what changed. The fourth quarter is covered by the annual report (Form 10-K) instead.
• Restated comparisons are flagged in the notes on this page. When a company redraws its segments or changes how it adjusts EPS, it restates the year-ago column, so the year-ago figure in a new release can differ from the one printed a year ago. This page always uses the comparison in the newer release, because that is the like-for-like one.
