Reported 13F long positions as filed for 2026-Q1 (change vs 2025-Q4). 13F covers US-listed long equity only — the sum is a LOWER BOUND on institutional ownership, never a total. % of shares outstanding not shown: no SEC cover-page share count falls within 120 days of the 2026-Q1 quarter end, so any percentage would rest on a count that cannot speak for this quarter. Holder share counts are shown as filed.
No reported quarters on file for PTN.
