Deal structure
Cash, stock, or mixed consideration changes the financing and share count.
Merger Model
Merger Model Interview Questions
Interviewers use merger-model questions to see whether you understand how a deal changes the income statement, capital structure, and earnings power of the combined company.
01 / UNDERSTAND THE CONTEXT
What merger-model questions are really testing
Most interviewers are not asking you to build a full merger model in your head. They are checking whether you understand the chain reaction: deal structure, financing, synergies, purchase accounting, and pro forma EPS.
That is why the best answers move from concept to driver to impact. They sound orderly because the candidate understands what changes first and what flows through later.
The moving parts you need to connect
A merger model is easier when you see it as a set of linked adjustments.
Financing effects
Interest expense and share issuance feed directly into pro forma earnings.
Purchase accounting
Goodwill, step-ups, and new intangible amortization all matter.
Synergies and costs
Recurring synergies help; one-time deal costs hurt near-term EPS.
02 / BUILD YOUR APPROACH
How to answer a merger-model question
Move from the deal mechanics to the earnings impact in a clean sequence.
- 1
Lay out the transaction
How is the target being purchased and how is the deal financed?
- 2
Adjust the income statement
Add target earnings, subtract financing costs, add synergies, and account for purchase-accounting changes.
- 3
Recalculate shares
If stock is used, update the share count and make sure the denominator is right.
- 4
Evaluate EPS impact
Compare pro forma EPS to standalone acquirer EPS and explain the main drivers of the change.
03 / SEE IT IN PRACTICE
The follow-ups candidates should expect
Interviewers often move from broad merger-model questions into narrower M&A logic.
Walk me through a merger model
What they ask
Whether you understand the high-level sequence instead of isolated concepts.
What sounds strong
Start with consideration and financing, then move to pro forma earnings adjustments and share count.
What sounds weak
Jumping into accretion dilution without explaining how the model gets there.
How do synergies affect the model?
What they ask
Whether you understand where recurring benefits show up and why one-time costs are treated differently.
What sounds strong
Explain that recurring synergies increase earnings, while deal costs are non-recurring and usually drag the near term.
What sounds weak
Saying synergies just make the deal accretive.
What does purchase accounting change?
What they ask
Whether you can connect the balance-sheet adjustments to the income statement.
What sounds strong
Mention goodwill, asset step-ups, and amortization or depreciation impacts where relevant.
What sounds weak
Ignoring purchase accounting completely.
Merger-model mistakes that weaken technical credibility
These are the common gaps that make candidates sound surface-level.
- Treating the model like a pure EPS math exercise.
- Forgetting that stock consideration changes the share count.
- Not mentioning purchase accounting in a full merger-model explanation.
- Confusing recurring synergies with one-time integration or transaction costs.
- Explaining the outcome without the sequence of how you got there.

Frequently asked questions
Do analysts ever get asked to build a full merger model in interviews?
For most IB interviews you explain the concept verbally, but some advanced or buy-side processes can include model-based tests.
Is accretion dilution the same thing as the merger model?
Accretion dilution is one output of the broader merger-model framework.
Do I need purchase accounting detail for first rounds?
You should know the basics, especially goodwill, step-ups, and how amortization or depreciation can affect earnings.
Make merger models feel logical, not memorized
If you can explain the sequence and the drivers, the technicals sound much sharper immediately.
