Perhaps the best starting point to locate company information is the company's website.  While the main audience of the company website are individual or business consumers, publicly traded companies will typically also include information for investors.  This information is often found in the website footer and researchers should scrutinize the website carefully to find this information.  

In this example, Microsoft has placed that information in the website footer under Company and tagged as Investors.  

Exploring the information provided through that link, the researcher will find a plethora of financial information and corporate information including annual reports and corporate philosophy.
