As DreamerMeg has stated, it really depends on where the company is headquartered. The little research I have done on non-US companies, if they are a publicly traded company on that country's stock exchange, particularly if they can be traded internationally, they probably file public forms similar to US and UK companies. If they are large enough, you may be able to find them on their websites. If not, write them directly with "Investor" on the outside of the envelop so they will direct the inquiry to the right department. Good luck/!
