Why does combined EV increase?

Lets say company A has EV of 100, Market Cap 80, Debt 20 and company B has EV of 50, Market Cap 30, Debt 20 When company A acquires company b, the combined EV is 180 (100+50+30) according to my notes I guess my question is, why does the acquisition result in a higher combined EV than simply adding the 2 together? Shouldn't the resulting EV by simply 100+50=150?

I think you missed the part of the textbook about "synergy." Also, if you acquire firm B at a premium, that would add to its Mkt. Cap, consequently, adding to its EV.

The difference between successful people and others is largely a habit - a controlled habit of doing every task better, faster and more efficiently.

I'm not sure the "premium" argument would necessarily work - as any premium paid would reduce firm A's EV as a cash outflow. If you do a share purchase, your EVs aren't affected - just split among a larger share base.

 

What if you used debt for the acquisition?
