When will Berkshire Hathaway Inc. file its next 10-Q?

Berkshire Hathaway Inc.'s most recent periodic report on file is a Form 10-Q for the period ended June 30, 2026, filed Aug. 10, 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, Berkshire Hathaway Inc. filed between 34 and 41 days after period end (median 35 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.
