JOHNSON & JOHNSON
$652M in tracked AUM across 16 positions as of Q1 2026.
Johnson & Johnson's Q1 2026 13F is a $652M, 16-position portfolio that is almost entirely composed of early-stage biotech and clinical-stage pharmaceutical names — the fund's AUM grew from $555.0M in Q4 2025 to $652.4M in Q1 2026 (+$97.4M, +17.6%), making it one of the few portfolios in this batch to experience net inflows during a quarter when many institutional funds were shrinking. The quarter's only structural changes were a new open in Rallybio ($1.4M, a CUSIP-migration artifact: the fund sold its Rallybio position under CUSIP 75120L100 and immediately reopened it under 75120L209, a different share-class or listing, with no net economic change) and the complete liquidation of Lyell Immunopharma ($1.7M, -$1.7M, -100%). The two largest positions — Protagonist Therapeutics ($258.1M, 39.6%, +$44.2M, +20.7% shares) and Nanobiotix ($173.6M, 26.6%, +$43.6M, +33.5% shares) — together account for 66.2% of AUM and were both significantly increased, signaling a manager that is concentrating rather than diversifying its highest-conviction biotech bets. The 18 total changes (1 new, 2 sold, 0 increased in share terms beyond the two largest, 1 decreased — Nano-X Imaging -$255K, -47.4%) is low churn for a biotech portfolio, which typically rotates rapidly; the stability here reflects a manager that has settled on a core set of 14-16 names and is adding to winners rather than constantly reshuffling. At a 77.50 whaleScore on $652M with 66.2% in two names, this is a high-conviction, concentrated biotech venture portfolio whose Q1 activity is best read as a manager taking profits on new inflows and deploying them into the two positions with the most advanced clinical catalysts (Protagonist's GI-and-inflammatory pipeline, Nanobiotix's nanomedicine-and-radiosensitization platform).
