What Is Adjusted EBITDA, and Why Does It Matter More Than Your Multiple?

If you've had any conversations about selling your contracting business, you've probably heard the word "multiple" thrown around a lot. What's the multiple in HVAC right now? What multiple did that guy in the next county get? Can I get a higher multiple?

Multiples matter. We're not going to pretend they don't. However, here's the thing: owners who spend all their energy chasing a better multiple while ignoring their adjusted EBITDA usually leave far more money on the table than any multiple negotiation could ever recover. Understanding how adjusted profitability works and how to maximize it helps you get the most money possible.

The EBITDA Equation

The purchase price formula for most contracting business sales looks like this:

Adjusted EBITDA × Multiple ± Cash and Debt = Purchase Price

EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It's a widely used measure of a business's cash-generating power, which really just means how much money the business actually produces before financing decisions, accounting choices, and tax strategies get involved.

The problem here is that raw EBITDA isn't what buyers are paying for. They're paying for adjusted EBITDA, which is a recast version of your income statement, which models what the business's cash flow will look like after the transaction closes, under the new ownership.

Think of it this way: your income statement right now reflects the decisions you made as the owner. Some of those decisions will look different to a buyer. The adjustment process is about making sure that’s accounted for. The buyer wants to know how decisions would pan out if they had made them.

What Adjustments Actually Do

Adjustments (sometimes called add-backs) work by stripping out expenses or income items that don't reflect the true, ongoing profitability of the business going forward. They recast your financials as if someone else had owned the company for the past three years.

Done well, this process can meaningfully increase your adjusted EBITDA, which, when multiplied by your deal multiple, can have an enormous impact on your final purchase price. You’ll find four categories that account for most adjustments.

Four Categories of EBITDA Adjustments

Adjustments vary significantly from business to business but often fall into one into a few general categories.

1. Owner Personal Expenses

This one is probably the most common and, for most owners, the most intuitive.

If your business has been covering personal expenses that wouldn't be paid for a typical employee, those get added back. It makes sense. After all, if the new owner isn't going to run those expenses through the business, they shouldn't count against the profitability that a buyer is purchasing.

Some of the more usual examples include things like personal vehicle expenses, personal or mixed-use travel, meals and entertainment, sporting event tickets, family cell phone plans, health or gym memberships, and charitable donations made through the business. The dollar amounts may seem modest on their own, but owners are often surprised by how quickly they add up across three years of financials.

2. Owner Compensation

If you're planning to step back or move on after closing, your compensation gets scrutinized closely, and there's an adjustment process that goes along with it.

At first, it seems simple: your salary, benefits, payroll taxes, and any retirement contributions all come out. That said, there’s an important question that has to be answered. Who's going to do what you were doing, and what will that cost?

If the business can run without your direct involvement because your team is already handling the day-to-day, the full compensation adjustment may stand. However, if the buyer needs to hire someone to fill your shoes, a negative adjustment (called an offset) gets applied to account for that cost.

This is one of the areas where building a management-independent business before you go to market pays the biggest dividends. The less indispensable you are, the cleaner the adjustment.

3. Extraordinary Items

These are one-time, non-recurring expenses that happened during the look-back period but aren't expected to happen again. Our general guideline: if you wouldn't anticipate something recurring within the next five years, it probably falls under this heading.

Real-world examples from contracting businesses include:

●      A catastrophic equipment failure

●      Disrupted business operations due to natural disasters/weather events

●      Severance pay for a key employee

●      Unusual situations that lead to significant legal/lawsuit fees

●      One-time executive search fees

●      Emergency facility repairs your insurance didn’t cover

The phrase "non-recurring" does a lot of work here, and buyers will scrutinize each one. You'll need to tell a credible story for each add-back. An experienced advisor helps you identify which items are defensible and how to present them.

4. Synergy Adjustments

This category is a little different from the others. Rather than capturing something personal to the owner, synergy adjustments account for costs that will likely disappear because the buyer already has those capabilities in place. In other words, something within their existing business setup offsets those costs.

The most common example is rent. If a buyer already operates out of a location close to yours, they may consolidate facilities post-close rather than carry two leases. In that case, your current rent becomes a legitimate adjustment because it's an expense that won't exist in the combined business.

Other examples include redundant software (think accounting platforms, field service management tools, and dispatch systems), IT support contracts, marketing and advertising spending that the buyer's platform will absorb, and some administrative or back-office costs that the acquirer can fold into their existing infrastructure.

It's worth noting: synergy adjustments are buyer-specific and even when they apply to a specific buyer, the buyer very well may not consider them a valid adjustment for the seller. The key for sellers is to leverage a competitive bid process to encourage buyers to consider some synergy adjustments as valid.

Why This Is Worth Your Time

Let's say your business generates $2 million in raw EBITDA, and you're negotiating a 6x multiple. That's a $12 million purchase price.

Now, let's say an experienced advisor works through your financials and identifies $400,000 in legitimate adjustments (owner comp, personal expenses, a couple of extraordinary items, and a synergy adjustment for redundant software). Your Adjusted EBITDA is now $2.4 million.

At the same 6x multiple, you're now looking at a $14.4 million purchase price. That's $2.4 million in additional value from doing the adjustment work the right way, and that's before you've negotiated the multiple.

Don't Leave It on the Table

Every contracting business has its own quirks, like unusual expense structures, owner arrangements, one-time events, or operational overlaps that don't show up cleanly in standard financial statements. Identifying and defending every reasonable adjustment requires someone who knows what to look for and how to present it to buyers in a way that holds up through diligence.

If you're starting to think about a potential sale, understanding your adjusted EBITDA now gives you time to clean things up, document adjustments properly, and enter a process from a position of strength.
