List 13D/13G filings (plus amendments) for an issuer, newest first.

Tool description as the model sees it

List Schedule 13D / 13G beneficial-ownership filings (and their amendments, 13D/A and 13G/A) for one issuer — AUTHORITATIVE source for “who owns 5%+ of $TICKER” and “has an activist filed a 13D on this company”. Takes a ticker or company name (auto-resolved to CIK) or a CIK directly. Each row flags structured: true/false — filings from SEC’s 2024 XML rule onward are structured and feed straight into sec_13d_filing; older ones are plain text/HTML only. Use sec_13d_filing on any accession_number returned here to get the actual reporting-owner data (percent of class, voting power, purpose).
