What is Form 20-F?

Form 20-F is the annual report filed by foreign private issuers, equivalent to the 10-K for domestic companies. It includes audited financials, risk factors, and a business overview.

Foreign issuers may report under IFRS or U.S. GAAP, and the 20-F is the cornerstone of fundamental analysis for non-U.S. listings.

The Finsider Form 20-F API standardizes these annual filings so you can analyze foreign issuers with the same workflow you use for 10-Ks.
