Move = the first close after the release against the close before it. A release after 4pm ET is priced by the next session; one before 9:30am ET by that day’s. Times are when the SEC accepted the 8-K (Item 2.02), which follows the press release by minutes. Closes held from Sep 2, 2025; “no price data” means we don't hold the closes for that report. 5 other Item 2.02 filings, filed weeks ahead of a report (a delivery or preliminary update), are not counted as reports. Prior-session closes only; not a forecast, not advice.
