Institutional owners (13F) 107 filers · $20.2M total · As of June 30, 2026

Institutions that report holding this stock in their quarterly SEC Form 13F. Long positions only; a single filer may appear twice for separate option legs. Large offsetting put/call legs typically reflect market-making or hedged inventory, not directional conviction.

Institutional activity — Q2 2026 vs prior quarter

New positions	Exited positions	Increased	Decreased	Net shares change
32 (+9 vs prior Q)	16 (+3 vs prior Q)	22 (-2 vs prior Q)	25 (+5 vs prior Q)	+4.3M

Compared to Q1 2026. SEC Form 13F filings are due within 45 days of quarter-end plus a short buffer for late filers — quarters still inside that window are skipped in favor of the most recent fully-reported pair.
