When does Ecolab Inc. (ECL) report earnings? On Oct 27, 2026, before the open

Of its last 12 earnings announcements: 12 before the open. Each one comes from the 8-K with item 2.02 that Ecolab filed with the SEC, paired with the 10-Q or 10-K for that same quarter: 69 quarters since Jul 28, 2009, and every row links to its filing.

Next announced date: Oct 27, 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.

ECL window: when it reported before the open or during market hours, from the previous close to that day's. Split-adjusted closes and EPS with its estimate, from Yahoo Finance. It already happened: it does not anticipate the next announcement.

Where each number comes from

From the 8-K with item 2.02 ("Results of Operations and Financial Condition") that Ecolab 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 is derived from the hours in which EDGAR accepts filings.

What this data does not know

• The exact time of the press release: the 8-K reaches EDGAR minutes or hours later, so Ecolab's median 08:07 is an upper bound. The session says which one the news landed in, not what minute it was said.
• Nothing before Jul 28, 2009: it is Ecolab's oldest quarter with announcement and report paired in the file.
• What will happen. The page's only future date, Oct 27, 2026, was announced by Ecolab on the Nasdaq calendar and can be moved. Ecolab reporting before the open 60 quarters in a row does not say the next one will be the same.
• Ecolab's identity is its SEC CIK (0000031462), not its symbol: symbols get recycled and renamed.
