When will Pfizer Inc. file its next 10-Q?

Pfizer Inc.'s most recent periodic report on file is a Form 10-Q for the period ended June 28, 2026, filed Aug. 4, 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, Pfizer Inc. filed between 36 and 38 days after period end (median 37 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.
