How to Answer “What is an earnout in M&A and what are the pros/cons for buyer and seller?” in Investment Banking Interviews
In earnout in M&A interview prep, this is a common prompt because it sits at the intersection of valuation, negotiation, and incentives. Interviewers want you to define the structure clearly and then explain the trade-offs—not just recite a dictionary definition.
For M&A interview questions like “What is an earnout in M&A and what are the pros/cons for buyer and seller?”, aim to (1) define an earnout, (2) describe how it’s typically set up (metrics, timing, governance), and (3) lay out the buyer vs seller earnout pros and cons with practical nuance.
What Interviewers Look For in M&A Technical Questions on Earnouts
This question tests whether you understand why earnouts exist: they are a pricing mechanism used when buyer and seller disagree on the target’s future performance, or when value depends on post-close execution (new products, customer retention, regulatory milestones, etc.).
It also checks deal judgment on M&A technical questions: what metrics are used (revenue, EBITDA, gross profit), how payments are structured (cliffs vs linear, caps/floors), and what can go wrong (gaming, integration decisions impacting performance, disputes over accounting policies).
Finally, it’s a communication test. Analysts are expected to explain the mechanics crisply, separate economics from legal terms, and show awareness of negotiation dynamics—an “investment banking interview strategies” skill that signals you can support live deal discussions and client questions.
Earnout in M&A Interview Prep: A Structured Answer Framework
- 1
Step 1: Define an earnout and when it shows up in M&A
Start with a one-sentence definition: an earnout is contingent consideration where part of the purchase price is paid after closing only if the target hits agreed performance targets over a set period.
Then add the “when”: earnouts are most common when valuation is uncertain or highly forecast-dependent—e.g., founder-led businesses, high-growth software, biotech with milestones, or carve-outs where standalone performance is hard to underwrite. In interviews, it helps to frame it as a risk-sharing bridge between a seller’s optimistic outlook and a buyer’s desire to avoid overpaying.
To keep it analyst-level, mention the link to valuation: the headline price may include “up to X” consideration, but the base/closing consideration is lower, with upside conditional on performance.

Step 2: Explain the key mechanics (metrics, period, measurement, governance)
Outline the moving parts interviewers expect in how to explain earnouts in M&A interviews:
- Performance metric: revenue, EBITDA, gross profit, ARR, customer retention, units shipped, regulatory/technical milestones. Highlight that metric choice drives incentives and dispute risk.
- Measurement period: often 1–3 years; sometimes multi-year with separate tranches.
- Payout shape: cliff (all-or-nothing at a threshold) vs linear/ratable; caps and floors; sometimes a “catch-up” mechanism.
- Accounting and definitions: what counts as revenue? which policies? treatment of one-offs, synergies, corporate allocations.
- Control and governance: who runs the business post-close, what operational covenants exist, and dispute resolution (auditors/experts).
Keep it practical: earnouts can fail not because the metric is wrong, but because definitions and control rights are vague.

Step 3: Lay out earnout pros and cons for buyers vs sellers (balanced)
Present the pros and cons of earnouts for buyers and sellers in a two-sided way.
For buyers (pros): reduces upfront cash/financing, limits overpayment if projections miss, and can keep management motivated post-close. It can also help win a competitive process without fully paying day-one.
For buyers (cons): creates integration constraints (can’t fully optimise if it hurts the metric), adds admin and dispute risk, and may encourage short-term behaviour to hit targets. If the business outperforms, total consideration can end up higher than a clean purchase price.
For sellers (pros): preserves upside if they believe in growth, can increase headline valuation, and may help get a deal done when bids are conservative.
For sellers (cons): they take execution/integration risk post-close, may lose operational control while being judged on results, and face potential metric manipulation or accounting disagreements.

Step 4: Add one concrete example and the main diligence / term-sheet checks
Close with a simple example to show you can apply it: “Buyer pays £80m at close plus up to £20m earnout if EBITDA reaches £15m in year 2, with a linear payout between £12m and £15m and a cap at £20m.”
Then mention the checks analysts support in practice (these are strong best practices for discussing earnouts in interviews):
- Is the metric aligned with value (e.g., EBITDA vs revenue when margins can change)?
- Are definitions tight (accounting policies, one-offs, intercompany charges)?
- Does the buyer have covenants to operate in good faith, and does the seller have visibility (reporting, audit rights)?
- Is the earnout duration reasonable and financeable, and what is the expected value under base/downside cases?
This shows you know what to know about earnouts in investment banking beyond the headline concept.
Analyst Model Answer: Earnout Pros and Cons (Buyer vs Seller)
An earnout is a form of contingent consideration in M&A where part of the purchase price is paid after closing only if the target achieves agreed performance targets over a specified period. It’s typically used when the buyer and seller disagree on the company’s future outlook and want a risk-sharing mechanism to bridge the valuation gap.
Mechanically, the parties negotiate the metric—often revenue or EBITDA—plus the measurement period, the payout shape (cliff versus linear), and key definitions like accounting policies and what items are excluded. Governance matters as well: because the buyer controls the business post-close, earnouts usually require reporting rights, clear calculation rules, and a dispute process to reduce ambiguity.
For the buyer, the upside is reducing upfront cash and limiting overpayment if performance disappoints, while still offering a competitive “headline” valuation. The downside is complexity and potential disputes, plus the earnout can constrain integration decisions if cost synergies or strategic changes would reduce the earnout metric.
For the seller, the benefit is retaining upside if they’re confident in growth and getting to a higher total valuation. The trade-off is that they’re exposed to post-close execution and integration risk, often without full control, and they may face disagreements over how results are measured.
As an example, a buyer might pay 80 at close plus up to 20 tied to hitting a year‑2 EBITDA target, with linear payouts and a cap. In diligence and term-sheet work, I’d focus on metric alignment, tight definitions, and governance so incentives and calculations are clear.
- Lead with the definition and purpose (bridging valuation gaps via risk sharing).
- Show you know the mechanics interviewers expect: metric, period, payout curve, definitions, governance.
- Balance buyer vs seller earnout pros and cons; don’t imply earnouts are always “good” or “bad”.
- Use one simple numeric example to demonstrate application without overcomplicating.
- Flag the real-world failure points: control, accounting definitions, disputes, integration constraints.
Common Earnout Pros and Cons Mistakes Candidates Make
- Describing an earnout as just “extra payment later” without stating it’s contingent on agreed performance targets and measured over a defined period.
- Only listing benefits (or only listing risks) instead of giving a balanced buyer vs seller view—interviewers expect the trade-offs.
- Ignoring metric definition and governance (accounting policies, control rights, dispute resolution), which is where many earnouts break down.
- Using unrealistic metrics or timelines (e.g., vague “growth” targets) rather than concrete measures like revenue/EBITDA and 1–3 year periods.
- Missing the integration point: earnouts can conflict with synergy capture and post-close strategic changes, creating friction and disputes.
- Confusing earnouts with seller notes/holdbacks; holdbacks are usually for indemnities, while earnouts are performance-based value sharing.
Follow-Ups You’ll Hear in M&A Interview Questions on Earnouts
How do earnouts affect valuation and the purchase price headline number?
They let parties show a higher “up to” purchase price while keeping lower guaranteed consideration at close; economically you’d value the earnout based on probability-weighted outcomes.
What metrics make a “good” earnout and when is EBITDA risky?
A good metric is hard to manipulate and aligned with value; EBITDA can be contentious if post-close allocations, one-offs, or integration costs materially affect the calculation.
What protections does a seller typically ask for in an earnout?
Clear definitions, reporting/audit rights, limits on accounting changes, and operational covenants (often framed as operating in good faith) plus a dispute-resolution mechanism.
How can earnouts create perverse incentives for management?
They can encourage short-term decisions to hit the metric—like delaying investment or pushing low-quality revenue—especially with cliff structures near a threshold.
Where do earnouts show up in the financial statements / deal consideration?
They’re contingent consideration; accounting treatment depends on standards, but conceptually they’re part of total consideration with later payments based on performance.
Investment Banking Interview Strategies to Nail Earnout Questions
- Practise a 60–90 second version: definition + why used + 2 buyer pros/cons + 2 seller pros/cons.
- Have one numeric example ready (base price + earnout cap + metric + period) and keep it simple.
- For M&A technical questions, rehearse the “failure points” list: metric definitions, control, integration constraints, disputes.
- Record yourself answering and check you clearly separate mechanics (how it works) from economics (why each side likes/dislikes it).
- Do a timed mock on AceTheRound and aim for crisp structure under follow-up pressure (metrics, governance, valuation impact).
