The activist-affiliated director's resignation and the appointment of an independent audit chair signal a potential normalization of board governance. Monitor for any future 13D amendments indicating stake changes or new demands, but near-term activist escalation appears unlikely.
Price Chart
Executive Summary
Perceptive Advisors filed an amended Schedule 13D disclosing that its Managing Director, Douglas Giordano, resigned from Kardigan's board on September 29, 2026. The filing shows Perceptive's aggregate beneficial ownership remains at 8.8% of common stock (8,254,144 shares including options), with no change in stake or new activist demands. The resignation of a board member affiliated with the activist investor, combined with the recent appointment of a new independent director, suggests a de-escalation of activist pressure rather than an escalation.
