The SEC requires that public companies disclose meaningful financial information to the public in order to achieve the concept that all investors, rather they be large institutions or private individuals, have basic information about an investment before they buy it and so long as they hold it. The filings collected by the SEC are searchable through EDGAR.

Corporate webpages will often have their latest financial reports available through an Investor Relations page. Try typing "[company name] investor relations" and then look for tabs relating to financial reports."

Example: "coca cola investor relations"
