When does LyondellBasell Industries N.V. (LYB) report earnings? On Oct 30, 2026, before the open

Of its last 12 earnings announcements: 11 during market hours (and 1 with no time on the filing). Each one comes from the 8-K with item 2.02 that LyondellBasell Industries filed with the SEC, paired with the 10-Q or 10-K for that same quarter: 61 quarters since Jul 29, 2011, and every row links to its filing.

Next announced date: Oct 30, 2026, before the open. It comes from the company through the public Nasdaq calendar, not from the SEC: it is a scheduled date and companies do move it. Everything else on this page already happened, with its filing attached.

Where each number comes from

From the 8-K with item 2.02 ("Results of Operations and Financial Condition") that LyondellBasell Industries filed on EDGAR, the SEC's public database; only those with their 10-Q or 10-K behind them count, so other 8-Ks with the same item (production figures, monthly sales) stay out. The time is converted to New York time using this specific company's stamp convention (its EDGAR stamp arrives in UTC), and it is not assumed: it was read off the filing's official header.

What this data does not know

• The exact time of the press release: the 8-K reaches EDGAR minutes or hours later, so LyondellBasell Industries's median 10:34 is an upper bound. The session says which one the news landed in, not what minute it was said.
• Nothing before Jul 29, 2011: it is LyondellBasell Industries's oldest quarter with announcement and report paired in the file.
• What will happen. The page's only future date, Oct 30, 2026, was announced by LyondellBasell Industries on the Nasdaq calendar and can be moved. LyondellBasell Industries reporting during market hours 3 quarters in a row does not say the next one will be the same.
• LyondellBasell Industries's identity is its SEC CIK (0001489393), not its symbol: symbols get recycled and renamed.
