How to read this data
14 of the 19 sales in the table are flagged as scheduled (10b5-1 plan): signed months ahead and executed automatically, so they say nothing about what the insider thinks today. Waste Management's single open-market purchase (code P) is the rare signal: insiders are already paid in stock, so buying more means putting in their own money. The latest filing is from Sep 8, 2026, and a Form 4 arrives up to two business days after the trade.
12 of the 20 rows in the table carry footnotes from the Form 4 itself, folded into the code column and copied verbatim; a row with no footnote means the filing has none.
