As well as the Libraries' databases I'm suggesting, I would also recommend going to the company's website, especially their investor relations page(s), if applicable. Libraries' databases are going to have variable coverage when it comes to international companies, so it's worth searching in more than one database for company profiles, etc. I very strongly recommend you choose public companies, as finding data on private companies is difficult to impossible.
What's on this page is by no means all relevant resources; just a few starting points. Please don't hesitate to reach out to me for further assistance.
