All publicly traded companies in the United States are required to file an annual statement, called a 10-k, with the US Securities and Exchange Commission. (Publicly traded companies in other countries have reporting requirements and governmental agencies of their own, which are not covered here.) The 10-k is a comprehensive, detailed report of a publicly traded company's business operations and financial condition. It's usually accompanied by additional statements: executive compensation, financial statements, and so forth. While publicly traded companies also file additional reports with the SEC (10-Qs or quarterly reports, for example), the 10-k is the most important for researchers.
Corporations based outside of the USA but selling shares on any US stock exchange are required to file a 20-f annual statement with the SEC. Similar in scope to the 10-k, its purpose is to standardize reporting for international companies.
By law, both the 10-k and the 20-f must be made available to shareholders. Companies usually comply with this requirement by posting the statements to their websites. You can also find 10-k and 20-f statements by searching the SEC's website search engine, EDGAR.
To learn as much about a company as possible, you should read the entire 10-k or 20-f, of course, including the attached supplemental documents. However, if you just need some background about the company in question, you can limit yourself to reading the following:
It's important to remember that CORPORATE websites are not the same as the websites one finds with a simple web search. Corporate websites are different from those websites in that they contain information of interest to potential investors, job applicants, and other persons more interested in the company's internal structures rather than the company's products or services.
The corporate website can be found by looking for the main website, then scrolling to the bottom and looking for a link to "Investor Relations" or "Company Information." The link may also be called "About the company" or "Investors."
For example: the main website for Lowes Home Improvement is http://www.lowes.com. If you go to that website, you'll see Lowes products:
This page exists to market Lowes goods and services. However, if you scroll to the bottom of this page, you'll see some additional links, including:
The link "Investors" takes you to the corporate website for Lowes, which has nothing on products bot a great deal about share prices, the corporate board, and other company-related issues.
