What if the target had net debt?
You’d calculate Enterprise Value (EV) = Equity Value + Debt – Cash, then size the deal off EV.
Net debt reduces equity consideration, so fewer new shares (or less cash/debt financing) is required.
Why does using stock help when the acquirer has a higher P/E?
When your P/E is high, your shares are “expensive” in earnings terms. Issuing high‑P/E stock to buy a lower‑P/E company means you give up fewer earnings per share than if you paid in cash or debt.
This makes the deal more likely to be accretive.
What happens if interest rates rise?
The cost of any new debt financing goes up → higher interest expense → lower pro forma net income → reduced EPS accretion (or potential dilution).
It also increases the discount rate in DCF/LBO IRR hurdles, making deals tougher to clear.
