Can a buyer reduce an earn-out by charging the acquired business its own corporate overhead?

The earn-out missed target. Operations were flat to slightly up. The gap was entirely new charges the business had never paid as a standalone company.

Short answer

Only if the earn-out’s own definition of EBITDA lets it. No statute governs how an earn-out’s EBITDA is calculated, so a buyer that integrates the target into its corporate group and starts charging a management fee, an IT allocation, or a share of group insurance can lawfully suppress the target’s reported post-closing earnings — unless the purchase agreement’s “Earn-Out EBITDA” definition specifically excludes exactly those corporate allocations.

The rule

The entire mechanic runs through the purchase agreement’s own defined term, because no statute defines EBITDA or governs an earn-out’s cost allocations. An “ordinary-course” covenant restrains how the buyer conducts the business, not how it accounts for what it charges the business — those are two different promises, and a buyer can honour both while still eating the earn-out through overhead it was never obligated to avoid charging.

When this changes

The fix is drafted before signing, not litigated after: an exhaustive exclusion list inside the “Earn-Out EBITDA” definition itself, excluding any new corporate or management fee, IT allocation, insurance charge or other cost the target never carried as a standalone business, anchored to the target’s own historical accounting rather than the buyer’s post-integration cost structure. A generic “operate in the ordinary course” covenant is not a substitute for that list — it restrains conduct, and charging a new allocation is an accounting choice, not a change in how the business is run day to day, so it slips past a conduct covenant cleanly. An audit right over the earn-out calculation helps a seller SEE the problem; only the definition itself stops the buyer from creating it.

The Canadian benchmark

What do businesses like this one actually sell for?

Canadian small-business transaction data is not published anywhere, so most valuations in this country quote an American benchmark. The Deavo–Treadstone Acquisition Index is a daily record of Canadian listings built to replace that: asking-price distributions by province and city are published now, and days on market, departure rates and asking-to-sale spreads follow as the series lengthens.
