Which agencies would still do well if all KPOP group sales would decline 30-40%?

Every big and mid tier company was doing just fine pre 2021 when average sales for all groups were 2 to 3 times lower than what they are right now

Most of them because kpop album sales can't be that profitable

The big 4 will still have enough endorsement and big touring acts and other source of income so they will barely suffer, mid tier companies will survive just fine. I think nugu groups and companies are the ones who benefited the most by kpop increase in sales because they barely get earnings from streaming, digital sales, barely have endorsements and cant tour but now ANYBODY can sell 50k-100k albums each comeback, and thats a pretty sweet amount of money. But losing 40% of sales wont kill most companies, now 80% and most of them are gone.

the exact same as the one's currently???
