Earn-Out Structuring

Step 1: Bridging the Valuation Gap

Earn-Out Amount = $180.0m − $150.0m = $30.0m

This $30.0m is the exact size of the disagreement between the two sides. Structuring it as a contingent earn-out rather than simply splitting the difference lets the buyer avoid overpaying if the seller's optimistic projections don't materialize, while giving the seller a path to the price they believe the business is worth if it performs as promised. This is precisely why earn-outs show up most often when the buyer and seller have genuinely different views on future performance, not just when they're negotiating over a known number.

Step 2: Present Value of the Earn-Out to the Buyer

PV of Earn-Out = $30.0m / (1.12)^2 = $30.0m / 1.2544 = $23.9m

Even before considering the probability of actually hitting the threshold, the $30.0m headline number is worth only $23.9m in present-value terms to the buyer, because it isn't paid until two years after close. This is a common negotiating point: sellers tend to anchor on the undiscounted headline figure, while buyers correctly value the earn-out on a discounted, risk-adjusted basis — and that gap in perspective is itself a frequent source of post-signing friction.

Step 3: Probability-Weighting the Payout

PV of payout in each scenario: Full = $30.0m / 1.2544 = $23.9m; Partial = $15.0m / 1.2544 = $12.0m; None = $0.0m.

Probability-Weighted PV = (0.40 × $23.9m) + (0.35 × $12.0m) + (0.25 × $0.0m) = $9.6m + $4.2m + $0.0m = $13.8m

This is the number that actually matters for both sides' economics: not the $30.0m cap, and not even the $23.9m full-payout present value, but the probability-weighted expected value of roughly $13.8m. In practice, this is why earn-outs so rarely close the full valuation gap they're designed to bridge — sellers who model the earn-out at its cap value are almost always overestimating what they'll actually collect.

Step 4: Designing Around the Common Failure Points

Because the buyer controls the board and capital allocation after close, and EBITDA is sensitive to overhead allocation, R&D spend, and investment timing, the seller is exposed to the buyer either deliberately or inadvertently suppressing the metric the payout depends on. The standard protections a seller negotiates for are: an anti-sandbagging / ordinary-course covenant requiring the buyer to run the business consistent with past practice during the earn-out period, standalone financial reporting so the acquired business's EBITDA isn't blended into the buyer's broader cost structure, and audit rights letting the seller's advisors verify the metric calculation independently each period.

These protections don't eliminate the buyer/seller conflict of interest inherent in earn-outs, but they're what separates an earn-out that functions as intended from the ones that end up in litigation — which, in practice, is a large share of them.

Final Results

• Earn-out size needed to bridge the gap: $30.0m
• Present value of a full payout: $23.9m
• Probability-weighted present value: $13.8m
• Key seller protections: anti-sandbagging covenant, standalone reporting, audit rights

This probability-weighted, discounted view of the earn-out is exactly what both sides' advisors model when deciding whether an earn-out actually closes a valuation gap or just defers the disagreement to a future dispute.
