Should we buy this business?
You are in this case when
- A named target and a price are already in the prompt.
- The client is the buyer, and the question is value and risk, not fit alone.
02 · Structure
Which drivers matter?
- 01
Strategic fit
Why own it?The objective, the target’s fit and the alternatives to buying.
- 02
Deal economics
Value versus priceStandalone value, synergies, premium, integration cost.
- 03
Execution
Can it be delivered?Integration, retention, systems, regulation and timing.
Buyer value created = standalone value + net synergies − purchase price
03 · Solve
Work the scratch sheet.
Illustrative practice scenarioA target has a standalone equity value of $80m. The purchase price is $100m. Synergies are worth $30m in present value; integration costs $8m in present value. All figures on one equity basis.
- What the buyer gets$80m + $30m − $8m = $102m
- What the buyer pays$100m
- Value created$102m − $100m = $2m
- Synergy shortfall that erases it$2m ÷ $30m = 6.7% of forecast synergies
Only $2m of buyer value remains in the base case. A 7% synergy miss erases it, so delivery probability and timing decide the recommendation.
Work backward from an answer
If the answer is “buy”, the synergies must be real, dated and owned by someone. So ask who delivers each synergy and when, before asking whether the price is fair.
04 · Recommend
Make the call in three buckets.
Do not pay $100m on these terms; offer $92m or walk.
Only $2m of value survives the base case, and a 7% synergy miss erases it.
Diligence the two largest synergies and the integration timeline. Risk: key-customer attrition during integration.
“I would separate strategic fit, deal economics and execution, and distinguish standalone value from buyer-specific synergies.”
Watch for: Do not count synergies twice or mix enterprise and equity values. Keep integration cost and timing explicit.
