Ask HN: Where does the money earned by succesful companies like Supercell go to?

I'm wondering, Supercell, the creator of the immensely popular games "clash of clans" and some other games, reportedly earns 2.5 to 5 million €€€'s a day!

In 2013, they earned €519 million

In 2014, they earned €1.545 billion

After expenses, like salaries (for their total of 152 employees), office space, marketing budget and perhaps some outsourcing. Say they have like a few hundred million left over after all expenses. Where does that money go to? Do they save it?
