In all the years that I have owned Amnf since 2005, it has never reported earnings, dividends or anything else after the close. It has also, to the best of my recollection, never reported anything ahead of the open. Reports and announcements have usually been between 11:00 A.M and 1:00 P.M. Eastern.
Actually, I would expect an earnings report on Thursday or Friday. Last year, the 3rd quarter report was on the 19th of October. That was a Friday. so, if things run true to form, I would expect a report on the 18th, a Friday - even Thursday would be a long shot.
