curious. how do you estimate how much an app is worth? Are you discounting future cash flows? If the total networth of Supercell is at 1.5B then selling it at 1.5B for 51% is not a bad deal (assuming that its value does not increase)
Big contrast to Gungho (the purchaser) and Rovio, which is worth $455,438,581 and $145,714,888.
We have models about revenue, user growth, user amounts, etc -- all valued per country, etc that we combine to make the estimation. Larger apps make this estimation a lot easier than indie apps, too. You can click through on each app and see more detailed info.
Rovio hasn't been a major player in terms of being a top grossing app recently -- they get good downloads and have brand presence, but in the age of IAP based free to play revenue (24 top grossing apps out of top 25 are free: https://sensortower.com/ios/rankings/top/iphone/us/all-categ...) Rovio's app based model isn't as sticky as long term freemium titles with long term progression. Not to say that Rovio isn't doing great in other parts of it's business!
1B of that being in Clash of Clans
Interesting to see them exit -- Clash of Clans hadn't showed signs of slowing down, especially given that they recently released on Android.
