Insights

Director received a routine stock grant and clarified prior indirect holdings.

Director Michael Ketslakh was granted 22,500 Common shares of Bridgeline Digital, Inc. as a compensation award at $0.00 per share on January 30, 2026. This is a non-cash equity grant, not an open-market transaction, so it carries limited trading signal.
