Contingent consideration is purchase price whose payment depends on future events — most commonly an earnout tied to the target hitting revenue or EBITDA targets after closing. Acquisition accounting (ASC 805 / IFRS 3) requires the acquirer to recognize this future, uncertain payment as part of the consideration on day one, measured at fair value — which creates some of the trickiest accounting in a deal.
Initial recognition: fair value at acquisition
At the acquisition date, the acquirer estimates the fair value of the contingent payment — the probability-weighted, discounted value of what it expects to pay — and includes it in the total consideration transferred (which in turn affects goodwill). So even an earnout that may never be paid is booked at inception at its expected value, not at zero and not at its maximum.
Subsequent measurement: the key complication
What happens after the acquisition date depends on how the contingent consideration is classified:
- Liability-classified (the typical cash earnout): it is remeasured to fair value every period, and the changes flow through profit or loss (earnings). As expectations about hitting the targets rise or fall, the liability is written up or down, injecting volatility into post-deal earnings that is unrelated to operating performance. A successful target that is beating its earnout targets paradoxically generates expense (the liability grows); a target that misses generates income.
- Equity-classified (e.g., a fixed number of shares): generally not remeasured — it stays at its acquisition-date value.
This remeasurement quirk surprises many acquirers and is a frequent source of "below-the-line" earnings noise after a deal.
Earnout vs compensation: a critical distinction
A recurring trap: if a contingent payment to a selling shareholder is conditioned on their continued employment, accounting standards often treat it as compensation expense (recognized over the service period) rather than as purchase consideration. The economic "earnout" the parties negotiated may therefore be split for accounting into part purchase price, part post-combination compensation — with very different earnings effects. How an earnout is structured (who receives it, whether it is forfeited on departure) drives this determination, so deal accountants scrutinize earnout terms closely.
Why it matters
Contingent consideration is where the deal structure meets the income statement. Acquirers must (1) get the acquisition-date fair value right (it affects goodwill), (2) anticipate the earnings volatility from remeasuring liability-classified earnouts, and (3) correctly bifurcate any portion that is really compensation. These issues make earnouts — already a negotiation and valuation challenge — a notable accounting challenge as well.
