Companies set trading windows, which usually close shortly before results and reopen after them, and insiders may trade under 10b5-1 plans adopted months earlier. A date alone does not show what a person knew or why they traded. Past release dates are the dates the company filed its 8-K with Item 2.02. An upcoming date, when one is mentioned, comes from the data provider's earnings calendar (Finnhub): it is not a company filing, it is not estimated by OQRO, and it may change.
