When will Amphenol Corp. file its next 10-Q?

Amphenol Corp.'s most recent periodic report on file is a Form 10-Q for the period ended June 30, 2026, filed July 31, 2026. Its fiscal year ends around Dec. 31, so the next period should close about Sept. 30, 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. 9, 2026 after moving off weekends and federal holidays. Over its last 8 10-Qs, Amphenol Corp. filed between 24 and 31 days after period end (median 26 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.
