ANAB ANAPTYSBIO, INC
Price Chart
Executive Summary
Dennis Mulroy, an officer of AnaptysBio, filed a Form 144 on June 5, 2026, indicating intent to sell 22,491 shares of common stock valued at approximately $1.15 million. The filing also reveals a pattern of recent sales totaling over 160,000 shares in the prior two weeks, suggesting a sustained insider selling campaign rather than a one-off liquidity event.
Actionable Insight
The sustained selling by an officer over multiple weeks is a bearish signal, especially given the historical underperformance of prior bullish calls on ANAB (T+20 win rate 33%). Monitor for additional Form 4 filings and any upcoming corporate events (earnings, pipeline updates) that could explain the selling. The stock's high analyst bullishness (94% buy ratings) contrasts with insider behavior, creating a potential divergence to watch.
Key Facts
- Officer Dennis Mulroy filed Form 144 to sell 22,491 shares valued at ~$1.15 million.
- The filing also discloses 13 prior sales between May 15 and June 4, 2026, totaling ~160,422 shares for ~$8.7 million.
- The proposed sale is attributed to a stock option exercise, but the aggregate selling pattern is substantial.
- Market cap is ~$1.5B, so the total disclosed sales (~$9.9M) represent ~0.66% of market cap.
- No other insider activity reported in the last 30 days per market data snapshot.
Financial Impact
Total disclosed insider sales of ~$9.9 million over the past three weeks, with the latest 144 adding ~$1.15 million.
Risk Factors
- Form 144 is an intent to sell; the sale may not be executed, but the pattern of recent completed sales is confirmed.
- The selling could be for personal diversification or tax planning, not necessarily a reflection of company outlook.
- High analyst consensus may already be priced in, and insider selling could precede negative news.
