These are the 10 biggest companies in the world by 12-month trailing (TTM) revenue, and they represent a striking diversity of industries. This list is limited to companies that are publicly traded in the U.S. or Canada, either directly or through American depositary receipts (ADRs).
Some foreign companies report semiannually, and so may have longer lag times. We add the caveat that two other companies that would otherwise be added to this list are Saudi Aramco, the Saudi state oil company; and State Grid, the Chinese state-owned electric utility. They were omitted because their stocks are not publicly traded in the U.S. or Canada.
