Company financial information can be found using a variety of sources such as government and commercial websites as well as databases. A good place to begin looking for financial statements is the company's website - look for links that say "About Us," "Investor Relations" or "SEC Filings".
Once you find a company's financial information, there are a few things you should pay attention to:
Date of the report/summary/conference
The currency used (U.S. dollars or Euro? Thousands or millions?)
The SEC’s EDGAR database provides free public access to corporate information, allowing you to quickly research a company’s financial information and operations by reviewing registration statements, prospectuses and periodic reports.
