Insider buying on Jan 8, 2026

On Jan 8, 2026, 18 insiders at 17 companies filed 31 purchases reported on Form 4, worth $18.0M in all, with a median purchase of $35.5K. The largest was Walters William Thurman, 10% owner of Zentalis Pharmaceuticals, Inc. (ZNTL), who reported buying 6,459,973 shares worth $7.8M. Officers accounted for 8 purchases, directors who are not officers for 9, and 10% owners with no board or officer role for 14. Chief executives and chief financial officers filed 5 purchases: Siokas Grigorios, Chief Executive Officer, Director, 10% owner of Cosmos Health Inc. (COSM); jeereddi Prasad Anjaneya, CEO, Director, 10% owner of Elite Health Systems Inc. (EHSI); Billingsley Chester, Chief Executive Officer, Director, 10% owner of Mentor Capital, Inc. (MNTR). 2 companies showed cluster buying, two or more insiders buying within 7 days: IVFH (4 insiders), SRZN (2 insiders). For 3 insiders of 18, this was the first purchase of that company's stock on our record. That is fewer than the 80 purchases filed on Jan 7, 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.
