Insider buying on Dec 18, 2025

On Dec 18, 2025, 55 insiders at 47 companies filed 84 purchases reported on Form 4, worth $45.0M in all, with a median purchase of $53.7K. The largest was Genmab A/s, 10% owner of MRUS, who reported buying 150,795 shares worth $14.6M. Officers accounted for 30 purchases, directors who are not officers for 23, and 10% owners with no board or officer role for 24. Chief executives and chief financial officers filed 17 purchases: Pompliano Anthony John III, Chief Executive Officer, Director, 10% owner of Silvia, Inc. (BRR); Siegall Clay B, President and CEO, Director of Immunome Inc. (IMNM); Labe James, Chief Executive Officer, Director of TriplePoint Venture Growth BDC Corp. (TPVG) among others. 18 companies showed cluster buying, two or more insiders buying within 7 days, among them NAVN (5 insiders), ELUT (5 insiders), CIK 1901037 (4 insiders), CBKM (3 insiders). For 9 insiders of 55, this was the first purchase of that company's stock on our record. That is fewer than the 90 purchases filed on Dec 17, 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.
