When does Thermo Fisher Scientific Inc. (TMO) report earnings? Before the open in 12 of its last 12 reports

Of its last 12 earnings announcements: 12 before the open. Each one comes from the 8-K with item 2.02 that Thermo Fisher Scientific filed with the SEC, paired with the 10-Q or 10-K for that same quarter: 66 quarters since Jul 23, 2009, and every row links to its filing.

Next date: the one TMO had announced, Oct 21, 2026, has already happened and its 8-K is filed (below). There is no further date yet inside the calendar this site covers (Oct 21, 2026 to Nov 24, 2026).

The latest, still without a report

• Oct 21, 2026, Wednesday at 06:03 New York time (before the open). see the 8-K

It is this company's most recent 8-K with item 2.02 and it does not yet have its 10-Q or 10-K behind it, so there is no way to say which quarter it belongs to: it does not enter the figures above or the table, and for the same reason it might not be an earnings announcement at all (some companies use this same item for production figures or monthly sales).

The last 20 quarters, one by one

"Lead": trading sessions between the announcement and the full quarterly report to the SEC (10-Q, or 10-K at fiscal year end). For Thermo Fisher Scientific, a median of 7 sessions over the last 12 quarters.

The table shows the 20 most recent quarters. All 66 are in the CSV, with the same columns and one row per quarter.

TMO 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 Thermo Fisher Scientific 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 Thermo Fisher Scientific's median 06:03 is an upper bound. The session says which one the news landed in, not what minute it was said.
• Nothing before Jul 23, 2009: it is Thermo Fisher Scientific's oldest quarter with announcement and report paired in the file.
• What will happen. Every date on the page already happened. Thermo Fisher Scientific reporting before the open 42 quarters in a row does not say the next one will be the same.
• Thermo Fisher Scientific's identity is its SEC CIK (0000097745), not its symbol: symbols get recycled and renamed.
