M&A case framework (With Examples): Interview Answer Guide 2027

An M&A case asks whether a company should acquire a target; analyze strategic rationale × valuation and financing × integration risk. A strong m&a case interview question answer starts with why the deal makes sense (synergies), checks the price is payable and justifiable, weighs integration risks, and compares alternatives like partnerships or building in-house.

What the M&a Case Interview Question Tests

Whether you separate strategic logic from financial logic — a cheap bad deal is still a bad deal.
Whether you can discuss synergies concretely: which costs, which revenues, and how credible they are.
Whether you address integration risk and alternatives instead of cheerleading the acquisition.

How to Answer the M&A Case Interview Question

See the framework judge three deals:

Example 1 — the good deal. Overlapping back offices, €40M cost synergies, 20% premium, same systems → accretive and integrable. Recommend yes.
Example 2 — the trap. 60% premium justified only by "revenue synergies" in a market where the acquirer has no presence, plus a founder-led culture → overpay plus integration risk. Recommend no.
Example 3 — the alternative wins. Target wants too much, but a 3-year exclusive partnership captures 70% of the strategic value at 10% of the cost → recommend partnering over acquiring.
The pattern. Rationale, credible synergies, price, integration, alternatives — the same five beats decide every deal.

Sample close: "M&A structure exists to kill bad deals early — most of its value is in the 'no'."

Common Mistakes With the M&a Case Interview Question

Valuing first, strategizing never: 'the DCF says buy' without asking why owning beats partnering.
Counting fantasy synergies — revenue synergies are the most overpromised and underdelivered.
Ignoring the acquirer's constraints: financing capacity, management bandwidth, and cultural fit.

M&A cases test commercial judgment under ambiguity — exactly what firms hire for. Candidates who challenge the deal's logic and price its risks sound like future partners; candidates who just add up synergies sound like spreadsheets.

FAQ

What is the framework for an M&A case?

Strategic rationale (why own vs. partner), synergies (cost, revenue, strategic), valuation and financing (can we pay, is it worth it), integration risks, and alternatives.

What are synergies in M&A?

Value created by combining: cost synergies (duplicate functions, scale purchasing), revenue synergies (cross-selling, new markets), and strategic ones (capabilities, talent). Cost synergies are most reliable.

How do you check if the price is fair?

Compare valuation multiples to comparable deals, test what synergies are needed to justify the premium, and check the acquirer's financing capacity and return thresholds.

What are the biggest risks in M&A?

Overpaying, failed integration (systems, culture, talent flight), and distracted management. Most deals underperform because integration was under-planned.
