Mandy isn’t doing...,

[Silverobama]

There’s a coffee shop here called Koala Coffee. It’s famous for its English club meetings. The shop owner used to be Gary but later Gary gave it to Mandy. Gary was losing money. A few days ago, someone told Mandy loses money too even though Mandy is a professional manager of restaurants and coffee shops.

I wrote “Mandy isn’t doing the business well either; She’s been losing money too”.

Is my sentence natural?

Under Mandy, the business isn't doing well either; it's been losing money.

A business and its owner are treated as separate entities.
