On Aug 28, 2026, 52 insiders at 43 companies filed 73 purchases reported on Form 4, worth $94.4M in all, with a median purchase of $27.9K. The largest was Cascade Investment, L.l.c., 10% owner of Republic Services, Inc. (RSG), who reported buying 211,098 shares worth $46.7M. Officers accounted for 23 purchases, directors who are not officers for 32, and 10% owners with no board or officer role for 15. Chief executives and chief financial officers filed 13 purchases: Siemiatkowski Sebastian, Chief Executive Officer, Director of Klarna Group plc (KLAR); Patel Viral, Chief Executive Officer, Director of CIK 1930054; Black Doug, CEO, Director of SiteOne Landscape Supply, Inc. (SITE) among others. 13 companies showed cluster buying, two or more insiders buying within 7 days, among them BIVI (4 insiders), HKHC (3 insiders), ATTO (2 insiders), JUSH (2 insiders). For 7 insiders of 52, this was the first purchase of that company's stock on our record. That is more than the 60 purchases filed on Aug 27, 2026. A Form 4 is due within two business days of the trade, so most of these purchases were made earlier in the week. Code P also covers shares bought privately from the company, so one large figure can be a negotiated placement rather than buying on the exchange.
