Release dates are when the company filed its earnings announcement with the SEC (Form 8-K, Item 2.02); select a date to open the filing. It usually reports 31–45 days after a quarter ends. Figures are USD in millions, except EPS. The colored percent is the change from the same quarter a year earlier. Until a quarter's 10-Q or 10-K figures reach the SEC's data, they come from the earnings press release, and are shown only when its year-ago numbers match the filed ones. A dash means the figure could not be confirmed yet.
