SEC API

Beneficial Ownership Report (Schedule 13D) SEC Filing API

Schedule 13D is the beneficial ownership report that any person or group acquiring more than 5% of a class of registered voting equity securities must file with the SEC, when the acquirer is not a passive investor. The filing discloses the acquirer's identity, source of funds, purpose of the acquisition, and any plans to influence control of the issuer. As of the SEC's 2024 rule update, initial 13D filings are due within 5 business days of crossing the 5% threshold. 13D filings are the primary signal of activist investor campaigns and pending control transactions. The SEC Filing API returns 13D filing URLs and dates for any public company by ticker.
