Explain the structure Debt/Shareholders’ Equity

Question

Our company (A) is going to buy the other company (B). We need to value the shares of B and, thus, we will use three options of the structure Debt/Shareholders’ Equity in order to obtain the WACC as:

1) Present structure of A and B, and

2) Structure used by A to finance the acquisition of B’s shares.

We will value the company B through applying these three options and then take as a reference average of the results. Is it correct?

Answer 1

That average has no sense. The relevant structure is the same to the one in three, but none of the ones specified is correct. The correct valuation is difference among the values of (A+B) after acquisition minus the value of A today.
