Executive Summary

Dennis Mulroy, an officer of AnaptysBio, filed a Form 144 on June 5, 2026, indicating intent to sell 20,000 common shares valued at approximately $1.04 million. The proposed sale follows a stock option exercise and is part of a broader pattern of insider selling, with Mulroy having sold over 126,000 shares in the prior three weeks across multiple transactions. While the filing itself is an advance notice of intent, the sustained selling by an officer warrants attention.
