Insider buying on Sep 11, 2025

On Sep 11, 2025, 41 insiders at 29 companies filed 66 purchases reported on Form 4, worth $67.2M in all, with a median purchase of $33.0K. The largest was Mubadala Investment Co PJSC, 10% owner of CIK 2006758, who reported buying 1,667,108 shares worth $43.3M. Officers accounted for 31 purchases, directors who are not officers for 27, and 10% owners with no board or officer role for 8. Chief executives and chief financial officers filed 19 purchases: Zanganeh Mahkam, Co-Chief Executive Officer, Director, 10% owner of Summit Therapeutics Inc. (SMMT); Duggan Robert W, Co-Chief Executive Officer, Director, 10% owner of Summit Therapeutics Inc. (SMMT); Golub David, President, CEO, Director, 10% owner of CIK 1901606 among others. 12 companies showed cluster buying, two or more insiders buying within 7 days, among them CAMP (7 insiders), BWFG (5 insiders), FRPT (5 insiders), OCTO (3 insiders). For 12 insiders of 41, this was the first purchase of that company's stock on our record. That is fewer than the 74 purchases filed on Sep 10, 2025. 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.
