Institutional owners (13F)
1 filer · $11K total · As of Dec. 31, 2025
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.
Insiders from SEC Form 3/4/5 filings; net = open-market P/S only
Activists & 5%+ owners
1 position
Investors who filed SEC Schedule 13D — beneficial ownership above 5% with an intent to influence the issuer (activist stakes, board campaigns, M&A). Each row shows the most recent known state of that filer's position.
Purpose is an automated classification of the filer's own stated purpose (SEC Item 4) — not investment advice. "—" means no clear purpose was stated or the text could not be classified.
ETF ownership
Held by 1 ETF
Weight reflects direct equity holdings (N-PORT) only; leveraged or derivative-based funds may hold additional swap exposure not shown.
