Relative valuation
Buying a lower P/E target with a higher P/E acquirer stock can be accretive in stock deals.

Accretion Dilution Interview Questions
Candidates often memorize the checklist and still miss the logic. Interviewers want to know what actually makes a deal accretive or dilutive and how financing choices change the math.
01 / UNDERSTAND THE CONTEXT
What accretion dilution really tests
This is not just a merger-model question. It is a test of whether you understand how deal financing, synergies, valuation multiples, and the relative earnings yield of the buyer and seller interact.
A good answer feels causal. A weak answer sounds like a list of bullet points you memorized from a prep guide without understanding the trade-offs underneath.
The main drivers you should be able to explain
If you know the drivers, the follow-ups become manageable.
Financing cost
Cheap debt often helps accretion; expensive financing can flip the answer.
Synergies
Cost synergies can offset purchase premium and financing drag.
Dilutive share issuance
More shares outstanding can reduce EPS even if the strategic deal logic is strong.
02 / BUILD YOUR APPROACH
How to answer accretion dilution questions cleanly
Focus on drivers, then explain directionally what each one does.
- 1
Define the concept
A deal is accretive if pro forma EPS goes up and dilutive if it goes down.
- 2
State the main drivers
Relative P/E, financing mix, synergies, purchase premium, and one-time costs.
- 3
Explain stock vs debt
Stock can be accretive if your shares are highly valued; debt can help if the after-tax cost is low.
- 4
Add nuance
EPS accretion does not automatically mean the deal is strategically good or value-creating.
03 / SEE IT IN PRACTICE
Where candidates usually get trapped
The interviewer is looking for causal reasoning, not just terminology.
What makes a deal accretive?
What they ask
Whether you understand the relationship between financing cost and the target's earnings yield.
Stronger answer
Explain how lower-cost funding and buying earnings cheaply can lift pro forma EPS.
Weaker answer
Saying synergies and cheap debt help without explaining why.
Is debt or stock more accretive?
What they ask
Whether you know the answer depends on valuation and financing context.
Stronger answer
Answer conditionally: debt is often accretive when cheap, but expensive acquirer stock can also make share issuance attractive.
Weaker answer
Always debt.
Does accretive mean a deal is good?
What they ask
Whether you understand the limitation of EPS as a metric.
Stronger answer
No. EPS accretion is one lens; value creation depends on strategy, price paid, integration risk, and returns.
Weaker answer
Yes, because shareholders earn more per share.
Accretion dilution mistakes to avoid
These mistakes tell the interviewer you memorized the topic instead of learning it.
- Treating EPS accretion as the same thing as value creation.
- Answering financing questions with one-word rules instead of conditional logic.
- Ignoring the effect of share issuance on the denominator.
- Not connecting purchase price to the returns the buyer is effectively acquiring.
- Forgetting that synergies can be the swing factor in borderline cases.

Frequently asked questions
Can a strategic deal be dilutive to EPS?
Absolutely. A deal can still make strategic sense even if short-term EPS is dilutive.
Why does a higher P/E acquirer help in a stock deal?
Because the acquirer can use relatively expensive stock to buy relatively cheaper earnings from the target.
Are synergies always included in interview answers?
Mention them if relevant, but make clear they are an assumption and not a free pass for an overpaid deal.
Know the drivers, not just the acronym soup
If you can explain what makes EPS go up or down and why, accretion-dilution questions stop feeling random.
