Equal partners each holding 33.3%.
This week we found out what Mercedes is up to as things were looking a little complicated. Toto Wolff was expected to leave to make way for Ineos (Sir Jim Ratcliffe), but no instead of going he has even more shares in the company.
Mercedes have reduced their share holding and Toto has increased his so everyone has 33% each and now everyone has an equal stake. I am sure part of the negotiation was to make sure Toto was still in charge and will be around for another 3 seasons. Lewis Hamilton will now sign a new contract and everything is back to normal.

Wales miss out as those plans have been tossed aside with Brexit in favor of France.
The Mercedes set up is by far the best managed team having strengths in all their different departments. Ineos are so entrenched with Mercedes these days as their Grenadier 4 x 4 will be built out of the recently bought ex Mercedes plant in France on the border with Germany in a town called Hambach. They will also manufacture the Mercedes Smart Electic city car as part of their negotiations. The $20 million sponsorship deal really opened doors and has made the two companies tighter than ever. Ineos have been quite open with the thought of introducing Hydrogen vehicles in the future and will need Mercedes Formula One technical input alongside the Mercedes knowledge.

Some say another boring year lies ahead as Toto remains in charge for 3 more years.
Toto will not change anything as you don't fiddle with a winning combination and even though he is George Russell's manager Bottas isn't going anywhere. Maybe another season or two and then he will join the team depending on what Bottas does this season. Another year of Mercedes dominance is on the cards however and it is for everyone else to catch them.
I don't think the other teams are inept and it is more like Mercedes is just better at everything they do. The FIA changing rules to stop their dominance hasn't worked yet and don't believe it will succeed any time soon. This must be seen more as a compliment that everyone is trying to change the rules to stop you and it has no affect. This must be the strongest team that Formula One has seen so far and believe with Ineos coming on board they just got stronger.
