This happens pretty frequently when one business buys over another.

They will likely offer you new employment contract under this new entity and considered you resigned from existing one. In this case, there wont be any compensation.

If you dont like new job, just hold on till current company goes in liquidation for compensation. That may worth it if you spent many years with current employer as package commensurate number of years.

Of course, you can try negotiate the deal to join new company which is likely best scenario.
