AnaptysBio insiders buy $11M shares
Watch: Watch Piper Sandler's next rating update for guidance on post-spinoff growth and legal risk impact.
AnaptysBio insiders led by ECOR1 CAPITAL bought $11.1M of shares at prices ranging from $12.92 to $36.50. Piper Sandler reaffirmed an Overweight rating but cut the price target to $93 after the April spinoff of First Tracks Biotherapeutics. The Delaware Chancery Court dismissed a breach of contract claim against ANAB in April. The stock trades near 52-week highs and shows decelerating revenue growth despite strong operating margins.
The insider accumulation and legal win support confidence amid mixed signals from modest analyst estimate revisions and recent insider selling. The spinoff refocuses ANAB as a royalty management company, altering growth drivers.
