Corning Inc. is expected to file its next quarterly report (Form 10-Q), for the period ending about Sept. 30, 2026, between Oct. 29, 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
Corning Inc.'s most recent periodic report on file is a Form 10-Q for the period ended June 30, 2026, filed July 29, 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, Corning Inc. filed between 29 and 33 days after period end (median 32 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.
