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.
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 3 ETFs
Weight reflects direct equity holdings (N-PORT) only; leveraged or derivative-based funds may hold additional swap exposure not shown.
