EBITDA is a number. Quality of EBITDA is a judgement about that number: how much of it will still be there in three years, how much of it depends on things the buyer cannot control, and how much of it can be believed at all. The judgement is what sets the multiple, and the multiple is what turns the same number into very different prices.
The characteristics that matter
What makes EBITDA high quality
- 01
Recurring or repeatable
Revenue that renews by contract, subscription or established habit, with churn measured and low. Project revenue that must be re-won each year is priced at a fraction.
- 02
Diversified
No customer, channel, vendor or product whose loss would change the picture. Concentration above a threshold is a risk buyers price explicitly.
- 03
Margin-stable
Gross margin that holds across periods and customers, with pricing discipline and cost visibility rather than a run of favourable quarters.
- 04
Cash-converting
EBITDA that turns into cash on a predictable cycle, with working capital under control. Earnings that sit in receivables and inventory are worth less.
- 05
Transferable
Earnings that do not depend on the founder's presence, a personal relationship or an undocumented process.
- 06
Reported reliably
Numbers produced on a calendar, reconciled to the bank, on a consistent basis, so that diligence confirms rather than rebuilds them.
How diligence tests it
A quality-of-earnings review begins by taking the reported EBITDA apart. It normalises for owner compensation and personal expenses run through the business. It removes one-time items in both directions. It restates revenue on a consistent recognition basis if the business has been inconsistent. It examines the top customers by revenue and margin over several years and looks at who owns each relationship. It walks cash from the income statement to the bank. Then it asks whether the monthly management accounts agree with the audited or reviewed annual figures, and if not, why.
What emerges is an adjusted EBITDA figure, often lower than the one presented, and a list of risks that each shave something off the multiple. The size of the gap between presented and adjusted EBITDA is itself a signal. A business whose reported number survives diligence largely intact is trusted on everything else; one whose number moves by a third is not.
Building quality in advance
Every one of the characteristics above can be built, and every one of them takes longer than a transaction timeline allows. Recurrence is built by changing contract terms and service models over renewal cycles. Diversification is built by deliberate channel and customer development over years. Margin stability is built by pricing discipline and cost visibility in the weekly review. Cash conversion is built by collections process and inventory discipline. Transferability is built by documentation and named owners. Reliable reporting is built by a monthly close that has held its calendar for at least twelve months.
This is the substance of what Opsist means by building toward an exit rather than preparing for one. The Exits page describes what buyers evaluate; the work that satisfies it happens years earlier, inside the operating rhythm, and it is the same work that makes the business better to run in the meantime.
Why it is worth more than growth
In the formula this site uses, enterprise value equals sustainable EBITDA multiplied by a market multiple, quality of EBITDA is the bridge between the two terms. It decides how much of the reported number counts as sustainable, and it decides where in the range the multiple lands. A business that raises quality without raising EBITDA at all can still be worth materially more. A business that raises EBITDA while lowering quality may be worth the same or less. The 10X arithmetic note shows how the two move together in an illustrative path.
