Context These purchases were made under the company’s ESPP (administrator-executed purchases), which are often pre-authorized plan transactions rather than opportunistic open-market buys. ESPP purchases are routine insider acquisitions and are factual signals of purchasing activity; they do not by themselves prove a change in company outlook.
