Q3 2026 data is still coming in (13F filing deadline: Nov 16, 2026), so these numbers are incomplete.

Institutional holders: 18; −1 vs. Q2 2026
Shares held: 217.5K; +5.24K (+2.5%) vs. Q2 2026
Total value: $4.73M; −$476.0K (−9.1%) vs. Q2 2026
New holders: 2; 9 more added
Sold out: 3; 5 more reduced

1,883 institutions that held it in Q2 2026 haven't filed for Q3 2026 yet. Not filing isn't selling, so they aren't counted as sold out or in the changes above.
