INVESTMENT BANKING · VALUATION
At 9.0× normalized EBITDA, what is the implied share price?
Reported consolidated EBITDA is $100m, after a one-off $10m legal expense. Normalize by adding back this expense.
- Debt
- $300m
- Excess cash
- $60m
- Minority interest
- $30m
- Diluted shares
- 50m
Show worked answer
Normalized EBITDA: $100m + $10m = $110m.
Enterprise value: 9.0× $110m = $990m.
Equity value: $990m − $300m + $60m − $30m = $720m.
Per share: $720m ÷ 50m = $14.40.

Amazing for banking interviews. The AI picked up on my weak spots in valuation and drilled me until I had it down cold.
