When will Southern Copper Corp. file its next 10-Q?

SCCO · NYSE
Snapshot

Southern Copper Corp. is expected to file its next quarterly report (Form 10-Q), for the period ending about Sept. 30, 2026, between Oct. 30, 2026 and Nov. 2, 2026, based on its last 8 10-Q filings. The SEC deadline for a large accelerated filer is Nov. 9, 2026.

How the next-report window is calculated

Southern Copper 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, Southern Copper Corp. filed between 30 and 33 days after period end (median 31 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.
