From personal experiences of mergers, though none this large...I have to imagine GEA in Louisville will be untouched for at least a year.
They have a large, formidable staff of engineers, marketers, salesfolk, test/QA technicians and a slew of manufacturing personnel at their FIVE plants.
I imagine Haier will leverage those resources.
However, I think we all know that there will be "synergies" and "streamlining" realized over time....as what these deals are usually all about. :/
