Controversially...Disney (

)
Well...at least in it's current from. Apparently their finances were not all that great before the pandemic, but they are now bleeding cash out of their many closed parks and attractions.
The brand itself would likely prevail for another 50 - 100 years but the corporation itself is now overloaded with the costs of all of the companies they bought in over the past decade, and apparently they may have been dodging taxes for even longer than that. If lockdowns of the parks continue into next year I'd be surprised if we see a complete Disney Corp. by 2030.
Likely broken up and sold off to various parties to settle debts and tax bills. The parks and movie production divisions might continue to exist under the Disney name but in a scaled back form and maybe even owned by another corporation.
Might see similar happen to a lot of other big studios too.
