JANA Partners Management, LP
$1.9B in tracked AUM across 12 positions as of Q1 2026.
JANA Partners Management's $1.92B 13F reflects a concentrated mandate in the 79-whaleScore bracket — a manager that has historically generated alpha through concentrated portfolio construction and event-driven or activist-adjacent research. Q1 2026 shows essentially flat AUM from the prior quarter ($1.92B to $1.92B) with an even distribution of increases, decreases, and new positions: 3 positions increased, 2 sold out, 3 reduced, 4 unchanged. That balanced activity pattern suggests JANA is neither aggressively building nor exiting — a neutral-to-cautious posture in a quarter where large-cap growth rallied. The WhaleScore of 79 reflects long-term performance that has rewarded this concentrated, event-aware approach.
