Institutional owners (13F)

17
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.
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.
