What Is Adjusted EBITDA in M&A??

---

When you look at acquiring a business, the first number people throw at you is EBITDA.

It’s supposed to tell you how profitable the company is. But EBITDA is sort of like a blurry photo. It gives you the outline, but not the details.

That’s why it needs to be adjusted.

Adjusted EBITDA takes the standard formula, earnings before interest, taxes, depreciation, and amortization, and cleans it up. You strip out the unusual items: one-time costs, owner perks, non-operating income.

What you’re left with is a clearer picture of what the business actually earns.

In other words, a better starting point for understanding what the company is worth.

Businesses love to talk about their EBITDA.

While it’s an important metric, a lot can be hidden inside an unadjusted number. A lawsuit settlement here, a founder’s car lease there. Even in industries that are considered stable, these items show up more often than you’d expect.

They affect the final number, but they don’t tell you how the business actually runs.

For example, a company might report strong EBITDA in a given year, but part of that could come from a one-time insurance payout. Without adjusting for that, you’re evaluating something that won’t repeat.

That’s where adjusted EBITDA becomes useful.

There are three main reasons this matters.

It shows the core operations
You see what the business generates from normal activity, without the noise.

It makes comparisons more accurate
Different companies structure debt and taxes differently. Adjusted EBITDA helps level the playing field when comparing multiples.

It gets closer to real cash flow
Cash is what actually matters. Adjusted EBITDA is a step toward understanding how much of it sticks.

In practice, adjustments tend to fall into a few categories.

One-time events
Legal costs, restructurings, or other non-recurring expenses.

Non-operating items
Asset sales or investment income that don’t reflect core operations.

Owner-related expenses
Personal expenses, above-market compensation, or perks that won’t continue under new ownership.

Unusual or external events
Things like natural disasters or temporary disruptions that distort earnings.

Taken together, these adjustments remove noise and help isolate the company’s true earning power.

Everyone in an M&A transaction pays attention to adjusted EBITDA, just for different reasons.

Buyers want to avoid paying for earnings that won’t continue after closing.

Sellers use it to present a clearer view of the business without one-off disruptions.

Investors rely on it to understand expected returns.

It becomes a shared reference point during the deal, what the business actually makes under normal conditions.

This is where a quality of earnings (QoE) report comes in.

It’s not enough to make adjustments and move on. Each one needs to be tested.

A QoE ties every adjustment back to supporting documentation. It validates whether those add-backs are real, reasonable, and likely to hold under new ownership.

Done properly, a QoE turns adjusted EBITDA from a marketing number into something buyers and investors can rely on.

It takes that blurry photo and brings it into focus.
