So this entity racks up a lot of debt (to Yandex) while making transfer payments to Yandex and then in a few years: "whoops, bankrupt!"
Now the equity holders (Uber) get wiped out and the company re-organizes and sells its assets (to Yandex) to pay off its debts (to Yandex) and Uber gets nothing.
Oh, NO! That's not legal! That's not fair! Good luck in Russian court buddy.
They are losing everything. They are burning another $225M to forestal the inevitable and pretend like it is not a complete loss but it is only a matter of time.
If Yandex can take Uber's stake, which is worth billions as you say, they would be stupid not to, and they can, so they will.
> In Russia, Yandex.Taxi has gross bookings of $1.01 billion on an annualized basis, while Uber had $566 million, according to a presentation prepared for investors.
Two companies will be merged (in Russia), but the brands will stay. The investment-stake asymmetry is probably due to the difference in the gross bookings.
"Uber will invest $225 million and take a 36.6 percent stake ... Yandex will invest $100 million and own 59.3 percent"
If they are paying twice as much as their partner for a minority stake I am pretty sure they will not be coming away with anything.
