When does Northrop Grumman Corporation (NOC) report earnings? During market hours in 12 of its last 12 reports

Of its last 12 earnings announcements: 12 during market hours. Each one comes from the 8-K with item 2.02 that Northrop Grumman filed with the SEC, paired with the 10-Q or 10-K for that same quarter: 70 quarters since Jul 23, 2009, and every row links to its filing.

Next date: NOC does not appear in the announced-earnings calendar this site covers (Oct 21, 2026 to Nov 24, 2026). When the company announces the day it will show up here; until then there is no date, and an estimate of ours would not be one.

NOC 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 Northrop Grumman 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 Northrop Grumman's median 10:45 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 Northrop Grumman's oldest quarter with announcement and report paired in the file.
• What will happen. Every date on the page already happened. Northrop Grumman reporting during market hours 39 quarters in a row does not say the next one will be the same.
• Northrop Grumman's identity is its SEC CIK (0001133421), not its symbol: symbols get recycled and renamed.
