SEC form types explained

Company reports

These forms describe the company, its results, or a material event.

• 10-K — annual company report.
• 10-Q — quarterly company report.
• 8-K — material company events.
• 20-F and 6-K — reports from foreign private issuers.

Ownership filings

Ownership forms answer different questions and should not be merged into one generic insider feed.

• Forms 3, 4, and 5 — insider beneficial ownership and changes.
• Schedule 13D and 13G — large beneficial owners.
• 13F-HR — institutional manager holdings.

Registrations and offerings

S-1, S-3, and 424B filings cover registrations, offerings, and prospectuses. DEF 14A covers proxy votes, boards, and executive compensation.

Amendments keep the form name

An amendment adds /A to the exact form, such as 10-K/A or 4/A. Narwhal keeps that token instead of hiding the amendment.
