Option 1: Company A calculates the WACC to discount cash flows to acquire a competitor. After acquisition Company A will then run company B exactly as it has been run before and will attain the same cash flows as Company B was getting before, while still operating Company A as usual.

Option 2: Company A calculates the WACC to discount cash flows to acquire a competitor. After acquisition, it will then end that companies operations and instead just use their factories to produce and sell their own products.

Does the WACC in option 2 differ from option 1? If so, in what ways?
