Publicly-held companies that meet certain size thresholds are required to file disclosure documents such as Form 10-K with the SEC. Form 10-K reports follow a format prescribed by the SEC and include a business overview, strategies, and competition (see Part I, Item 1 of 10-K); audited financial statements; discussion of products, markets, and distribution channels; names of subsidiaries; and information on management and ownership.
Such companies also usually issue annual reports to shareholders which include audited financial statements, the President's Letter, and glossy photos and other graphical information on products and results. Recent annual reports to shareholders are usually available at the corporate website under a heading such as Investor Relations.
