Yes, this means the ExxonMobil is equavilent to that economic powerhouse of the World, Bulgaria. It edged out the world renowed economic master of Lithuania.
A rather meaningless number. How many individuals around the world are stock holders are in ExxonMobil? I would guess it may exceed the population of these countries as well.
At the same time, ExxonMobil paid over $105 Billion in Taxes. Where do the taxes paid ranked compare as countries GDP? Moves quite a bit farther up the list.

As I said, that figure is true for Exxon Mobil ALONE. Combine it with the other “Big Five” and the economic clout these megaliths swing is on par with an industrialized nation. Add in the state-owned oil powerhouses and it is arguable that the oil industry commands economic power in excess of most nations on earth.
