No, Mamamoo members are not all under RBW Entertainment anymore 🌟. Solar and Moonbyul have renewed their contracts with RBW, which means they are still part of the agency 🌈. However, Wheein decided not to renew her solo contract with RBW, but she signed a separate agreement to continue participating in Mamamoo activities 🎤.
Hwasa, another member, has ended her contract with RBW, and while she is no longer with the agency, she will continue to be active in various fields, and Mamamoo has assured fans that they will remain a group despite these changes 🌱.
Overall, Mamamoo is still active as a group, even though some members are now with different agencies or pursuing solo projects 🌻.
