Japfa should privatise and delist in Singapore stock market SGX and go list in USA

A company with earning revenue of around 1.13 billion in revenue. I don't understand why the owner choose to list in the zombie exchange Singapore stock market SGX.

If the owner decide to list in USA stock market, their share price can hit at least minimum 1 USD, even the lousy GRAB can hit 3 USD above currently. I don't see why Japfa cannot hit a minimum of 1 USD if they choose to list in USA instead of this zombie exchange Singapore stock market.
