“Understanding EBITDA vs SDE: How to Value Your Business the Right Way”

Why EBITDA Matters (But Not Always).

When I sit down with business owners to talk about valuation, one theme comes up time and time again: confusion about the numbers that really matter. In our last valuation guide, I walked you through SDE (Seller’s Discretionary Earnings) and why it’s the right way to value most small, owner-operated businesses. It’s simple, it’s practical, and it reflects the real economic benefit a single owner gets from running the business.

But once a business grows beyond the owner… everything changes.

That’s when people start talking about EBITDA with a level of reverence usually reserved for sacred texts: “This company is worth 5× EBITDA.” “Private equity only cares about EBITDA.” “My mate sold his business for a massive multiple based on EBITDA.”

And sometimes that’s true. Sometimes EBITDA is exactly the right tool.

But here’s the problem: EBITDA is misunderstood more than almost any other financial metric. I’ve met owners who think EBITDA is cash in the bank. Others think it’s a magic number that automatically multiplies their valuation. Some assume that every business is valued this way, when in reality, EBITDA is completely inappropriate for most owner-dependent small businesses.

This blog is here to cut through the noise.

I’m going to break down what EBITDA actually means, why buyers use it, when it gives a clean picture of performance—and when it makes a complete mess of things. Because the truth is simple:

➡ EBITDA is a powerful valuation tool for the right type of business.
➡ It’s a dangerous and misleading tool for the wrong type.

If you understand the difference, you’ll not only know how to value your business properly, you’ll know how to increase that value in the years ahead.

2. What Exactly Is EBITDA?

Before we go any further, let’s strip EBITDA right back to basics. No jargon. No accounting waffle. Just plain English.

EBITDA stands for:

• Earnings
• Before
• Interest
• Taxes
• Depreciation
• Amortisation

That’s it. But what does that actually mean?

When I’m explaining EBITDA to business owners, I tell them this:

“EBITDA is a way of showing how much profit your business produces from its core operations, before we consider anything to do with financing, tax decisions, or long-term asset purchases.”

It’s meant to remove the “noise” from the numbers so you can see the engine of the business without the extras bolted on. Let me break it down.

Earnings (E)

This is your operating profit, the money your business makes from actually doing what it does. Not interest income. Not investments. Not things on the side. Just trading.

Before Interest (I)

Interest is removed because it depends on how the business is financed. One buyer might use debt. Another might pay cash. EBITDA strips it out so buyers compare businesses on performance, not funding structure.

Before Taxes (T)

Different owners structure their taxes differently. EBITDA removes those decisions to keep valuations consistent.

Before Depreciation (D) & Amortisation (A)

These are accounting charges for assets you bought years ago, such as machinery, vehicles, software, intellectual property, and so on. They affect your accounting profit, but they don’t reflect day-to-day operations.

Amortisation is the gradual write-down of intangible assets like software, patents, or goodwill. It’s similar to depreciation but for non-physical assets. Crucially, it’s a non-cash expense; no money leaves the bank.

EBITDA adds it back to show true operating performance without legacy accounting adjustments.

So what does that actually leave us with?

A version of profit that says:

“If someone else bought this business, ignored the current owner’s tax setup, ignored how it’s financed, and ignored non-cash accounting charges… how profitable is it really?”

That’s the logic.

It’s why private equity loves EBITDA. It’s why brokers use it for larger businesses. It’s why you’ll hear big multiples thrown around in the press. But there’s a catch, and it’s a big one. EBITDA works beautifully only when the business is already operating like a professionally managed company, where the owner can step away without the entire operation grinding to a halt.

If that’s not the case (and for many small businesses it isn’t), then EBITDA can tell a very misleading story. And that’s exactly what we’ll explore in the next section.

3. The Big Difference Between SDE and EBITDA

If you only take one thing away from this blog, let it be this:

• SDE tells you what the business is worth to one owner-operator.
• EBITDA tells you what the business is worth as a fully managed company.

Most small business owners don’t realise how big that difference is. They look at other businesses selling for “6× EBITDA” and immediately think their business should be worth the same. It won’t be, not if the business still relies heavily on them. Let me explain.

What SDE Actually Measures

SDE (Seller’s Discretionary Earnings) is the valuation method we covered in the previous blog. It’s built around a simple question:

How much financial benefit does one owner get from running this business?

It includes:

• The owner’s salary
• Profits
• Perks
• Personal expenses run through the business
• One-off costs
• Add-backs
• Any discretionary spending

It’s perfect for businesses where the owner wears several hats: salesperson, manager, operations lead, relationship holder, problem solver, and sometimes chief fire-fighter. Most small businesses fall into this category.

What EBITDA Measures

EBITDA, on the other hand, assumes this: The business can run with a management team in place, not the owner. It strips out the owner completely. It represents the performance of the business as if a board or management team replaced you tomorrow. That’s why larger businesses use EBITDA. That’s why private equity values businesses this way. And that’s why the multiples are typically larger, because the risk is lower when the business doesn’t depend on the owner to survive.

Why This Difference Matters for Valuation

Here’s the mistake I see almost every week: A business owner making £400k profit tells me, “I should get 5× EBITDA.” Sounds great. But then I ask:

• Who brings in the main clients?
• Who handles the key relationships?
• Who does the strategic thinking?
• Who signs off on the projects?
• Who is the business built around?

If the answer is “me” for most of these…that business does not have an EBITDA valuation model. It has an SDE valuation model. In other words, the value is not based on profit; it’s based on the benefit to a single owner. And that usually produces a very different number.

A Simple Comparison Table

Aspect	SDE	EBITDA
Best For	Owner-operated businesses	Management-run companies
Owner Dependency	High	Low
Includes Owner Salary?	Yes – added back	No – must be deducted
Suitable Revenue Range	£0–£5M	£5M+
Buyer Type	Individuals, trade buyers	Private equity, institutional buyers
Typical Multiple	1×–3×	4×–10×+

This table alone stops many owners from overvaluing their business or misunderstanding what buyers are really looking for.

The Punchline

If your business needs you every day, it’s an SDE business. If your business runs without you, it’s an EBITDA business. The sooner a business moves from the first category to the second, the more valuable it becomes.

4. When EBITDA Is the Right Valuation Method

There’s a moment in a business’s life where it evolves from being “the owner’s job” into something bigger, a proper company with real structure, a real team, and real systems. When that happens, the valuation method needs to evolve, too. That’s when EBITDA becomes the right tool.

Over the years, I’ve noticed the same pattern: once a business stops relying on the owner to personally hold everything together, buyers shift their focus from SDE to EBITDA. And with that shift comes higher multiples, more interest from buyers, and a level of valuation credibility you simply can’t get when the business still revolves around one person.

Let me break down the key situations where EBITDA does make sense.

4.1. When the Business Has a Management Team in Place

If your business continues running tomorrow without you, because you’ve hired managers, delegated decisions, and built systems, then EBITDA is absolutely the right valuation method.

Buyers don’t want a business they have to personally run. They want something they can step into or invest in without becoming the new firefighter. When the business is genuinely managerial, EBITDA becomes the cleanest measure of performance.

In short: if the business doesn’t fall over when you take a holiday, you’re probably EBITDA-ready.

4.2. When Revenue Is Typically Above £5M (or EBITDA Above £1M)

This isn’t a hard rule, but it’s a very reliable marker. At around £5M revenue or £1M EBITDA:

• You tend to have a leadership team, or at least senior staff.
• You have repeatable processes rather than heroic effort.
• You have defined roles, responsibilities, and reporting lines.
• You have customers who buy from the business rather than the owner.

By this stage, buyers automatically expect to value using EBITDA because the business is no longer “an owner’s lifestyle operation,” it’s a proper commercial asset.

4.3. When the Owner Is Not Essential to Day-to-Day Operations

This is the big one. If the owner no longer:

• Sells the big contracts
• Delivers the service
• Builds customer relationships
• Makes key decisions
• Knows every job, every client, every problem

…then EBITDA becomes the right way to value the business. In other words:

If the owner is replaceable, the business is EBITDA-ready.

And this is exactly why so many valuations jump massively once the owner steps back; the perceived risk drops, and the EBITDA multiple rises.

4.4. When the Industry Naturally Uses EBITDA Multiples

Some sectors are almost always valued on EBITDA, regardless of business size. This includes:

• Manufacturing
• Engineering
• B2B services
• Distribution
• Logistics
• Construction
• SaaS and tech (though with special adjustments)

In these industries, buyers are experienced, financially sophisticated, and expect to compare deals based on EBITDA. SDE simply doesn’t fit the picture.

4.5. When Buyers Include Private Equity or Institutional Investors

Private equity firms live and breathe EBITDA. They use it because:

• It’s comparable across businesses
• It ignores owner salary decisions
• It isn’t distorted by financing choices
• It highlights operational efficiency
• It fits their investment model

If your business is attracting these types of buyers (or you want it to), then learning to present your numbers using EBITDA is not optional. It’s essential.

The Real Message

EBITDA is the right tool only when the business stands on its own two feet. Not on the owner’s personality. Not on their energy. Not on their relationships or technical knowledge.

When a business reaches that level of maturity, EBITDA becomes the fairest, most accurate, and most attractive way to measure value, because buyers can finally see the business itself, not the person behind it.

5. When EBITDA Gives a Misleading Valuation

EBITDA can be incredibly useful, but only when you’re using it in the right context. When you apply it to the wrong type of business, it creates a completely false picture of value. And this is exactly where many small business owners get caught out.

I regularly see owners frustrated because their accountant, broker, or friend has told them their business should be valued at “6× EBITDA.” But for many small businesses, EBITDA is the worst number you could use. It makes them look more profitable than they really are and gives unrealistic expectations of value.

Let’s break down the key situations where EBITDA becomes dangerous.

5.1. When the Business Is Dependent on the Owner

This is the number-one problem. If you remove the owner and the business falls apart, then EBITDA is meaningless. It’s like valuing a car without the engine. Examples include businesses where the owner:

• Brings in most of the clients
• Does the technical work
• Manages staff personally
• Makes all strategic decisions
• Has the main customer relationships
• Holds the specialist knowledge

If that sounds familiar, your business is an SDE business, not an EBITDA business.

Using EBITDA here inflates the valuation massively because it ignores the cost of replacing you, which buyers absolutely will not ignore.

5.2. When the Owner Takes a Very Low (or Very High) Salary

Owners often underpay themselves for tax reasons or overpay themselves to draw money out of the company. EBITDA wipes out the owner’s salary entirely, which is fine for large businesses with management teams, but in an owner-run business, it produces a deeply misleading number.

Buyers will adjust EBITDA by adding back a market salary for your role. Once that’s done, the “true” EBITDA is often much lower than the figure the owner expected.

5.3. When the Business Has Inconsistent or Unstable Profits

Some businesses have:

• Big seasonal swings
• Project-driven revenue
• One-off contract wins
• Large year-to-year variations

EBITDA assumes stable, repeatable, operational profit. If your profit fluctuates wildly, your EBITDA might look great one year and terrible the next, which makes it a weak foundation for valuation. In these cases, SDE helps smooth out the peaks and troughs and provides a more accurate picture of owner benefit.

5.4. When Customer Concentration Is High

If more than 20–25% of your revenue comes from one or two clients, EBITDA massively overstates your value. Why? Because EBITDA doesn’t reflect the risk of losing that client. A business with £500k EBITDA but a single dominant customer is far riskier than one with £500k EBITDA spread over hundreds of stable clients.

Buyers will discount your valuation heavily, even if the EBITDA looks healthy.

5.5. When the Business Requires High Capital Expenditure (CapEx)

EBITDA removes depreciation, which is fine for low-capital industries. But for capital-intensive businesses, transport, machinery hire, manufacturing, and engineering, depreciation is a real economic cost. You do need to replace vehicles, equipment, and machinery. EBITDA ignores this reality.

So your EBITDA might show a strong profit…but your cash flow tells a completely different story. Buyers know this, and they will not value you based on an inflated EBITDA figure that ignores the need to reinvest in assets.

5.6. When Profitability Is Driven by the Owner’s “Superpower”

Some owners are:

• Brilliant salespeople
• Incredible negotiators
• Highly skilled technicians
• The face of the brand
• Trusted experts in their field

That’s wonderful, but it’s not transferable.

If your business relies on you being exceptional, EBITDA won’t show the true risk. Buyers will discount heavily because they know they cannot replace your personal superpower.

The Bottom Line

EBITDA only works when the business is a machine that runs without the owner. If the business relies on the owner, EBITDA is not just inaccurate; it’s dangerous. Using it in the wrong context can make owners believe their business is worth far more than any buyer is willing to pay. And nothing kills a sale faster than unrealistic expectations.

6. Why Some Businesses Need “Adjusted EBITDA”

If there’s one phrase that causes more confusion than EBITDA itself, it’s Adjusted EBITDA. Yet this is the version buyers and investors actually care about, because raw EBITDA rarely tells the whole story.

When I review a business for valuation, I almost never use the EBITDA straight from the accounts. It’s too messy, too influenced by the owner’s decisions, and too full of one-off events that don’t reflect the ongoing performance of the company.

That’s why we use Adjusted EBITDA. It strips out the distortions and gives a cleaner, more realistic picture of what the business will earn under new ownership. Let me break it down.

What Adjusted EBITDA Actually Means

Adjusted EBITDA takes the normal EBITDA figure and adds back or removes anything that is:

• Non-recurring
• Owner-specific
• Discretionary
• Unusual
• Not required for a new owner

In other words:

“Adjusted EBITDA tells buyers what the business will really earn once the current owner is gone and all the one-off noise is removed.”

This is the number that matters. This is the number used in serious valuations. And this is the number private equity focuses on.

The Most Common Adjustments

Here are the adjustments I use most often when valuing a business.

6.1. Adjusting for the Owner’s Role

If the owner works in the business but doesn’t pay themselves a market salary, or pays themselves too much, that needs fixing. Buyers want to know:

• What does it cost to hire someone to replace the owner?
• What is the real profitability once that cost is included?

If you ignore this, EBITDA becomes meaningless.

6.2. Removing One-Off or Non-Recurring Costs

Examples:

• Legal fees for a one-time dispute
• Redundancy payments
• Relocation costs
• One-off marketing campaigns
• Consultancy for a special project

These don’t reflect ongoing operations, so they are added back.

6.3. Removing One-Off or Unrepeatable Revenue

This is often overlooked. If you had a huge contract that won’t repeat, buyers will discount it from your performance. A one-off revenue spike inflates EBITDA unfairly, and buyers know it.

6.4. Adjusting for Discretionary Expenses

Many owners run personal or discretionary costs through the business:

• Personal travel
• Owner’s car
• Owner’s health insurance
• “Lifestyle” costs
• Excessive entertaining
• Family members on the payroll

All of these get added back because they won’t continue under new ownership.

6.5. Related-Party Transactions

If the business:

• Rents property from the owner at below-market rates
• Buys goods from a related company at reduced cost
• Uses family labour at discounted rates

…these distort EBITDA.

Buyers adjust them to reflect market rates, not friendly ones.

Why Getting Adjusted EBITDA Wrong Can Ruin a Sale

I’ve seen owners massively overvalue their business because they rely on their accountant’s EBITDA figure instead of a properly adjusted one. Then, when real buyers analyse the numbers and strip out the artificial inflation, the valuation collapses.

On the other hand, a carefully calculated Adjusted EBITDA:

• Enhances buyer confidence
• Reduces negotiation friction
• Justifies a higher multiple
• Makes the business look cleaner and more professional
• Positions you as an informed, well-prepared seller

If you want private equity, strategic buyers, or serious investors to take you seriously, Adjusted EBITDA is non-negotiable.

The Real Point

EBITDA is only the starting point. Adjusted EBITDA is the true valuation number. It shows the business as it will operate for the next owner, not how it operates today with the current owner’s quirks, perks, and one-off decisions baked in. The cleaner your Adjusted EBITDA, the stronger your valuation.

7. EBITDA Multiples: How Buyers Actually Use Them

Whenever someone talks about business valuation, the conversation eventually turns to “multiples.” It’s the part everyone gets excited about:

• “That business sold for 7× EBITDA.”
• “Our sector is trading at 5–8× EBITDA right now.”
• “Private equity pays at least 6×.”

But here’s what most small business owners misunderstand:

Buyers don’t just multiply your EBITDA by a number they found on Google. Multiples aren’t fixed; they are earned.

The same EBITDA can produce wildly different valuations depending on the risk profile, growth potential, and transferability of the business. Two companies with identical EBITDA can easily be worth millions apart.

Let me show you exactly how buyers actually use EBITDA multiples in the real world.

7.1. Buyers Use Multiples to Compare Similar Businesses

Multiples are a shorthand for market value. If similar companies in your industry consistently sell for 5× EBITDA, buyers will use that as a benchmark. It’s no different from house prices in your local area; the market sets the range. But here’s the important bit:

“5× EBITDA” is just the starting range, not the final decision.

Your business has to justify being at the top, middle, or bottom of that range.

7.2. The Multiple Depends on Risk; Higher Risk = Lower Multiple

Buyers care far more about risk than revenue. Here are the biggest risk factors that push your multiple down:

• Heavy owner dependency
• Concentration of a few big customers
• Weak management team
• Inconsistent profits
• No documented processes
• High staff turnover
• Poor financial reporting
• Heavy reliance on the owner’s personal expertise

Even with strong EBITDA, these issues can drag the multiple from 6× down to 2× very quickly. I’ve seen businesses with beautiful numbers get slashed in valuation simply because the owner was still the “glue” holding everything together.

7.3. The Multiple Goes Up When Buyers See Stability and Scalability

If EBITDA reflects a well-run, transferable business, the multiple rises. Here’s what boosts it:

• A reliable management team
• Recurring revenue streams
• Strong customer retention
• Clearly documented processes
• Diversified customer base
• Predictable cash flow
• Strong brand and market position
• Contracted revenue (e.g., maintenance contracts, subscriptions)

These reduce buyer risk, and higher certainty commands a higher multiple.

7.4. Industry Matters: Some Sectors Naturally Trade Higher

Different industries have very different norms. Examples (general ranges, not guarantees):

• Manufacturing: 4×–6×
• B2B services: 4×–7×
• Engineering: 5×–8×
• Healthcare: 6×–9×
• Tech/SaaS: 8×–20× (with the right metrics)
• Retail and hospitality: 2×–4×

Buyers look at your sector first, and then at your business-specific factors.

7.5. Growth Potential Has a Massive Impact

Two companies might both have £1M EBITDA…But:

• Company A is flat, has no innovation, and is owner-dependent.
• Company B is growing 20% a year with systems, processes, and a team.

Company A might get 3× EBITDA. Company B might get 8×.

Same profits. Seven-figure difference in valuation.

This is why I often tell owners:

“Buyers don’t pay for where your business is. They pay for where they believe it can go.”

7.6. Strategic Buyers vs. Financial Buyers. Multiples Differ

Financial buyers (private equity)

They want clean numbers, scalability, and transferable operations. They pay based on pure financial return.

Strategic buyers

They may pay far more because your business offers:

• Access to new markets
• A new customer base
• Unique capabilities
• Cost-saving synergies
• Strategic advantage

A strategic buyer might pay double the EBITDA multiple simply because your business fits their bigger plan. This is why positioning matters.

7.7. Why Two Businesses With the Same EBITDA Can Have Very Different Values

Here’s a real-world example I often use:

Business 1: £750k EBITDA

• Owner heavily involved
• One major customer (40% of revenue)
• No management team
• Patchy financial reports
• No recurring revenue

Valuation multiple: 2.5× Estimated value: £1.875M

Business 2: £750k EBITDA

• Strong management team
• 250 loyal customers
• Documented systems and processes
• Recurring revenue model
• Clear growth strategy

Valuation multiple: 6× Estimated value: £4.5M

Same EBITDA. Huge difference in valuation.

The Real Message

Don’t get fixated on “what multiple your sector uses.” Your job is to build a business that earns a high multiple by reducing risk, increasing stability, and proving the business can grow without you.

EBITDA is the starting point. The multiple is the judgment call buyers make about your business’s quality.

8. Why EBITDA Isn’t Cash Flow

If I had a pound for every business owner who confused EBITDA with cash flow, I could retire tomorrow. It’s one of the most common misunderstandings in valuation, and one of the most damaging.

On the surface, EBITDA looks like a great indicator of profitability. And it is… but only if you understand what it leaves out. The danger is that many owners (and even some accountants) treat EBITDA as if it’s “money in the bank,” when in reality, it’s often miles away from the cash the business actually generates.

Let me walk you through why.

8.1. EBITDA Removes Real, Everyday Cash Costs

EBITDA deliberately strips out:

• Interest
• Taxes
• Depreciation
• Amortisation

That’s fine for valuation comparisons, but it means EBITDA ignores real cash leaving the business, such as:

• Loan repayments
• Corporation tax
• VAT liabilities
• Asset replacements
• Finance leases
• Equipment upgrades

A business might show £500k EBITDA…but if it spends £300k replacing machines or vehicles every year, that EBITDA number is fantasy.

8.2. Working Capital Changes Can Make or Break Cash Flow

Working capital is the money tied up in:

• Stock
• Debtors (customers who owe you money)
• Creditors (suppliers you owe money to)

EBITDA ignores all of this.

Imagine this:

• You grow rapidly.
• Your sales look great.
• Your EBITDA looks fantastic.

But your customers are paying 60 days late, while your suppliers want payment in 30 days. Where does the cash come from? It comes from you, usually through overdrafts, loans, or personal injections. This is why EBITDA is a poor predictor of cash flow. Growth consumes cash faster than EBITDA can explain.

8.3. Capital Expenditure (CapEx) Doesn’t Show Up in EBITDA

Many industries rely heavily on equipment, vehicles, machinery, or technology. These assets wear out and need replacing, often at significant cost. But EBITDA completely ignores CapEx. This is why I tell owners:

“If your business needs constant reinvestment to stay operational, EBITDA can be dangerously misleading.”

For example:

• Manufacturing
• Transport
• Construction
• Plant hire
• Engineering
• Modular buildings
• Any asset-heavy business

These sectors can show strong EBITDA while bleeding cash.

8.4. EBITDA Excludes Debt Service Costs

It doesn’t matter how profitable you are on paper if you have:

• Loan repayments
• HP agreements
• Asset finance
• Bank debt
• Director loans to repay

…these payments erode cash flow significantly. EBITDA pretends these obligations don’t exist. A business making £400k EBITDA but spending £300k servicing debt is not a high-value business. Buyers know this. EBITDA alone hides the truth.

8.5. Compared to Cash Flow, EBITDA Often Paints a Rosier Picture

Here’s a simple example:

Business A

• £600k EBITDA
• £180k tax
• £90k interest
• £150k CapEx
• £100k working capital increase

Actual free cash flow: £80k. That’s a long way from £600k.

This is why sophisticated buyers don’t just look at EBITDA; they dig into cash conversion, debt levels, and CapEx requirements. Because what really matters is:

‘How much cash is left over once the business has paid for everything it actually needs to operate?’

8.6. So Why Use EBITDA at All?

Because, despite its flaws, EBITDA is:

• Comparable across companies
• Independent of owner decisions
• Easy to calculate
• Useful for understanding operational performance
• Standard for investors, brokers, and PE firms

But it was never designed to replace cash flow. It was designed to highlight core profitability before external factors. Think of it as a starting point, not the final truth.

The Bottom Line

EBITDA is a measure of operational performance. Cash flow is a measure of business reality.

Confuse the two, and you’ll:

• Overvalue your business
• Misjudge affordability
• Run into cash problems
• Misunderstand what buyers will actually pay

Get them both right? Then you have a powerful understanding of how your business really works.

9. The Red Flags Buyers Look For When Reviewing EBITDA

Whenever a buyer looks at your EBITDA, they don’t just accept the number at face value. They dissect it. They interrogate it. They stress-test it. Because EBITDA, on its own, is easy to manipulate intentionally or unintentionally.

I’ve seen owners proudly present EBITDA figures that look fantastic… only for buyers to pull them apart in minutes. Not because the owner was dishonest, but because they didn’t understand what buyers look for.

If you want a strong valuation (and a smooth deal), you need to know the red flags buyers search for and, more importantly, fix them before you go to market. Let’s go through the big ones.

9.1. Declining Revenue Hidden Behind “Good EBITDA”

This is one of the biggest traps. An owner cuts costs, freezes hiring, and tightens everything up. EBITDA goes up. But revenue is quietly slipping. A buyer sees right through it.

To them, declining revenue = declining future EBITDA = declining value.

If EBITDA improves while revenue drops, buyers suspect artificial inflation.

9.2. EBITDA Boosted by Reducing the Owner’s Salary

Some owners drop their salary to “make the numbers look better.” But buyers always ask:

“What does it cost to replace the owner with someone competent?”

If your EBITDA looks strong only because you underpay yourself, that number gets adjusted, sometimes brutally. I’ve seen EBITDA cut in half simply because the owner didn’t include a market salary for their role.

9.3. One-Off Wins Treated as Normal Earnings

Examples:

• A large contract that won’t repeat
• A temporary boom year
• Pandemic-related surges
• A single windfall customer
• A one-off sale of inventory

These inflate EBITDA unfairly. Buyers want repeatable, stable, transferable earnings. If a big chunk of your EBITDA came from a one-time event, buyers strip it out, and your valuation comes crashing down.

9.4. Deferred Maintenance or Underinvestment

This is a sneaky one.

Some owners:

• Delay equipment replacement
• Cut staff training
• Reduce marketing spend
• Underinvest in systems or technology

This boosts EBITDA in the short term but creates long-term problems. Buyers see a “clean” EBITDA and immediately ask:  “What is the seller NOT spending money on?”

If a business shows high profits but everything looks worn-out, outdated or understaffed, buyers assume the real EBITDA is much lower.

9.5. Customer Concentration Risk

If one customer represents more than 20–25% of your revenue, it’s a MASSIVE red flag. Even with strong EBITDA, customer concentration indicates high risk. Buyers respond by:

• Cutting the multiple
• Discounting EBITDA
• Adding earn-outs
• Reducing the upfront payment

A business with diversified revenue might sell for 6× EBITDA. A concentrated one? Sometimes only 2×.

9.6. EBITDA That Doesn’t Convert to Cash

Buyers dig into cash flow immediately. If you claim £700k EBITDA but only generate £120k actual cash, buyers know something is wrong.

Possible causes:

• Large working-capital swings
• Slow-paying customers
• High CapEx
• Heavy debt
• Excessive stock holding
• Aggressive revenue recognition

EBITDA without cash conversion is worthless. Buyers call it “paper profit.”

9.7. Poor Quality Financial Records

Nothing kills trust faster than messy numbers.

Buyers hate:

• Inconsistent bookkeeping
• Missing documentation
• Unexplained adjustments
• Erratic margins
• Unreliable management accounts
• Conflicting figures between systems

A strong EBITDA number built on weak accounting is a red flag by itself. Sophisticated buyers always assume: Poor records = higher risk = lower valuation.

9.8. EBITDA Distorted by Related-Party Transactions

If you:

• Pay yourself below-market rent
• Buy from your own supplier company
• Pay family members for roles they don’t perform
• Use subsidised services
• Benefit from non-standard pricing

…your EBITDA is artificially inflated. Buyers normalise these costs to market rates, and the adjusted EBITDA often drops sharply.

9.9. Heavy Reliance on the Owner’s “Personal Magic”

This is more common than owners realise. Even if your EBITDA looks amazing, buyers will downgrade it if the business relies on your:

• Personal reputation
• Technical expertise
• Sales genius
• Relationships
• Charisma
• Decision-making
• Daily involvement

Because none of that transfers in a sale. A business built on the owner is not valued like a business; it’s valued like a job. EBITDA doesn’t reflect this risk, so buyers adjust the valuation to reality.

The Takeaway

Buyers don’t just look at your EBITDA. They look through it. They’re searching for risk, instability, and anything that suggests your profitability won’t survive after you leave. If you want a strong valuation:

• Clean up your books
• Remove the one-off noise
• Reduce dependency
• Improve cash conversion
• Strengthen systems and management
• Diversify customers
• Present a stable, repeatable EBITDA

That’s what serious buyers pay for. Not the number in the accounts, but the confidence behind it.

10. The Smart Business Owner’s Takeaway

If you’ve made it this far, you already understand more about valuation than most business owners ever will. And that’s exactly the point: most people misunderstand EBITDA, misuse it, or assume it automatically makes their business worth more than it is.

Here’s the truth I’ve learned after years of valuing businesses of all shapes and sizes:

• There is no “one-size-fits-all” valuation method.
• The right method depends entirely on how your business actually operates.

Let me break down the key lessons as plainly as I can.

10.1. If your business relies on you, it’s an SDE business.

If the phone stops ringing when you’re away…If customers want you, not the business…If you’re the strategic brain, the top salesperson, the fixer, the negotiator, the operator…Then you simply aren’t selling a self-sustaining asset yet. Your business is valued on SDE because buyers must replace you, and that has a cost.

This isn’t a bad thing. It’s simply reality for most small businesses.

10.2. If your business runs without you, it’s an EBITDA business.

Once the business:

• Has a management team
• Has processes and systems
• Has customer relationships that don’t rely on you
• Has predictable revenue
• Has clean financial reporting

…then EBITDA becomes the right valuation tool.

This is where the multiples rise. This is where private equity becomes interested. This is where your business stops being “your job” and becomes a true commercial asset.

10.3. The valuation formula matters far less than the underlying drivers.

I can put two businesses side by side with identical EBITDA and show you two completely different valuations. Why? Because buyers don’t pay for numbers, they pay for:

• Stability
• Predictability
• Transferability
• Scalability
• Risk reduction
• Management capability
• Cash flow conversion

EBITDA is only the starting point. What matters is the quality behind it.

10.4. Your job is to make your business easier to buy.

This is where most owners focus on the wrong thing. They obsess over:

• Multiples
• Market rumours
• Headlines
• What someone else’s business sold for

But the real work ( the work that creates value) is much simpler:

• Reduce dependency on you.
• Document the processes.
• Build a management team.
• Diversify your customer base.
• Strengthen cash flow.
• Present clean, credible numbers.

Do that, and your EBITDA multiple naturally rises. No hype. No guesswork. Just a higher value through better fundamentals.

10.5. The smartest owners prepare years before they sell.

A business doesn’t magically become valuable the moment you decide to sell. Valuation is built over years of decisions, good or bad. If you want to exit:

• Strong
• Confident
• And with the highest possible valuation

…you need to understand whether your business is really an SDE business or an EBITDA business today, and what it needs to become before it’s truly valuable.

The Bottom Line

EBITDA isn’t good or bad. It’s not right or wrong. It’s only useful when applied to the right type of business. The real value for owners (especially small business owners) is knowing which model applies to you and what you need to change to move up the valuation ladder.

Most owners never take the time to understand this. The ones who do? They sell for significantly more.

11. Final Word: Get Your Business Valuation Snapshot

If this blog has done one thing, I hope it’s this: helped you see your business through the eyes of a buyer. Because that’s where real valuation clarity begins. Most business owners have no idea whether their company should be valued on SDE or EBITDA, and even fewer know what their true adjusted number actually looks like. They’re running blind. They’re guessing. They’re hoping.

Hope is not a strategy when it comes to the biggest financial event of your life.

That’s why I offer a Business Valuation Snapshot — a straightforward, practical review that shows you exactly:

• Whether your business should be valued on SDE or EBITDA
• What your true adjusted earnings look like
• How does your valuation compare to others in your sector
• The key risks buyers will spot instantly
• And the exact steps you need to take to increase your valuation over the next 12–36 months

No waffle. No jargon. No complicated spreadsheets. Just a clear, honest valuation picture, explained in plain English.

For many owners, this is the first time they’ve ever truly understood what their business is worth today… and what it could be worth tomorrow with the right plan. If you’re thinking about selling, planning your exit, or simply want to strengthen the business so it’s worth more in the future, this is the smartest next step you can take.
