Insider buying on May 18, 2026

On May 18, 2026, 98 insiders at 74 companies filed 183 purchases reported on Form 4, worth $186.5M in all, with a median purchase of $84.6K. The largest was Cascade Investment, L.l.c., 10% owner of Republic Services, Inc. (RSG), who reported buying 151,554 shares worth $31.4M. Officers accounted for 65 purchases, directors who are not officers for 69, and 10% owners with no board or officer role for 48. Chief executives and chief financial officers filed 55 purchases: Brisby Dominic, Chief Executive Officer, Director of Nomad Foods Ltd (NOMD); Myers Franklin, CEO and President, Director of HF Sinclair Corp (DINO); Moulder Leon O Jr, Chief Executive Officer, Director of Zenas BioPharma, Inc. (ZBIO) among others. 30 companies showed cluster buying, two or more insiders buying within 7 days, among them VITL (10 insiders), SHAK (6 insiders), VIDA (5 insiders), TLSI (5 insiders). For 40 insiders of 98, this was the first purchase of that company's stock on our record. That is more than the 148 purchases filed on May 15, 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.
