When will Lockheed Martin Corp. file its next 10-Q?

LMT · NYSE
Snapshot

Lockheed Martin Corp. is expected to file its next quarterly report (Form 10-Q), for the period ending about Sept. 27, 2026, between Oct. 20, 2026 and Oct. 22, 2026, based on its last 8 10-Q filings. The SEC deadline for a large accelerated filer is Nov. 6, 2026.

How the next-report window is calculated

Lockheed Martin Corp.'s most recent periodic report on file is a Form 10-Q for the period ended June 28, 2026, filed July 23, 2026. Its fiscal year ends around Dec. 31, so the next period should close about Sept. 27, 2026, and that report is a Form 10-Q.

SEC rules give a large accelerated filer 40 days after period end to file a 10-Q, which lands on Nov. 6, 2026 after moving off weekends and federal holidays. Over its last 8 10-Qs, Lockheed Martin Corp. filed between 23 and 25 days after period end (median 23 days), which gives the expected window above. Period ends are estimated from the company's own calendar and may shift by a few days in 52/53-week fiscal years.
