Insider buying on Oct 29, 2025

On Oct 29, 2025, 38 insiders at 24 companies filed 57 purchases reported on Form 4, worth $112.3M in all, with a median purchase of $31.5K. The largest was Catalyst4, Inc., 10% owner of MapLight Therapeutics, Inc. (MLPT), who reported buying 5,441,176 shares worth $92.5M. Officers accounted for 30 purchases, directors who are not officers for 15, and 10% owners with no board or officer role for 9. Chief executives and chief financial officers filed 15 purchases: Eliasek M Grier, Chief Executive Officer, Director of PAYIX; Brass Steven A, President and CEO, Director of Wd 40 Co (WDFC); Hall Martin Lance, OBK COO, Origin Bank Pres&CEO of Origin Bancorp, Inc. (OBK) among others. 8 companies showed cluster buying, two or more insiders buying within 7 days, among them OBK (9 insiders), WDFC (4 insiders), NMRA (3 insiders), FFIN (3 insiders). For 7 insiders of 38, this was the first purchase of that company's stock on our record. That is more than the 49 purchases filed on Oct 28, 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.
