Module 2: Deconstructing Valuation Multiples: SDE vs. EBITDA Multiples by Industry & Size Tier

Learning objectives and prerequisites

By the end of this lesson, you should be able to translate SDE into managed-business earnings and compare pricing. Prerequisite knowledge: Normalization and owner labor. Work from assumptions to equations, explain the acquisition consequence, and record the evidence needed to rely on the answer.

A multiple is meaningful only when its earnings are meaningful

A seller offers Apex Fire & Security for $4.2 million and says the price is modest because the company generates nearly $1 million of owner earnings. A buyer sees the same price as expensive because recurring managed EBITDA is only $800,000. The disagreement may concern the denominator more than the price.

A valuation multiple expresses a relationship between a defined price and a defined earnings measure. It is not an independent fact about an industry. A business can simultaneously sell for 3.9 times SDE and 4.75 times EBITDA because SDE and EBITDA describe different operating arrangements. The first task is to reconcile those arrangements.

All monetary amounts in this chapter are actual US dollars. Apex and the industry examples are fictional unless a specific published observation is identified. The 2.0x–3.5x SDE and 4.0x–6.5x EBITDA bands are teaching orientations, not sourced current industry medians. Do not present the tables as a broker's price sheet.

What SDE measures and what it combines

Seller's discretionary earnings, or SDE, often estimates earnings before the compensation and certain discretionary expenses of one working owner. Definitions vary among brokers and data providers. It can be useful for a buyer who intends to perform the owner's job, but it combines labor compensation with return on invested capital.

Consider a shop generating $350,000 SDE. If the required owner role would cost $140,000 to replace, managed EBITDA is closer to $210,000 before other adjustments. An owner-operator may value the opportunity as both a job and an investment. A passive buyer must pay someone to do the work, so its available operating return differs.

This does not make SDE illegitimate. It makes the intended buyer and convention important. The same salary cannot be treated as removable for valuation and indispensable when explaining why the business deserves a premium for exceptional management. Price the required organization consistently.

An SDE figure also remains before taxes, equipment investment, working-capital growth, and acquisition debt service. Calling it cash flow in a listing does not mean the buyer can withdraw that amount every year. Course 3's debt waterfall begins only after those demands are defined.

EBITDA after the owner's replacement organization

For this course, normalized EBITDA includes market-based compensation for all labor needed to operate after closing. It corrects accounting errors and removes supported owner-specific or exceptional expenses while retaining recurring replacement costs. Buyer synergies and unimplemented growth initiatives remain separate.

Apex reports EBITDA of $710,000. Its owner receives $240,000 compensation, and a fully burdened replacement manager costs $180,000. Verified personal expenses of $20,000 disappear, and $30,000 of truly exceptional repair expense is removed. A required market lease costs $20,000 more than the related-party historical charge.

Apex recurring earnings bridge	Effect
Reported EBITDA	$710,000
Remove recorded owner compensation	+$240,000
Include replacement management	($180,000)
Remove verified personal expenses	+$20,000
Remove exceptional repair expense	+$30,000
Normalize occupancy cost	($20,000)
Normalized managed EBITDA	$800,000

Under a disclosed one-owner SDE convention, adding back the replacement-manager amount produces $980,000 SDE. These are two views of the same economics. The additional $180,000 is the cost of a job, not a second pool of profit.

Assume the base replacement plan covers all continuing owner functions and the exceptional repair adjustment does not eliminate required ordinary repairs or replacement CapEx. If diligence disproves those assumptions, the bridge changes before any debate about the multiple.

Convert the multiple without changing the value

At the eventual $3.8 million operating value, EV/EBITDA is $3.8 million / $800,000 = 4.75x. On the stated SDE convention, price/SDE is $3.8 million / $980,000 = 3.8776x. A higher denominator produces a lower multiple for the same price.

The exact relationship is useful when comparing broker and buyer presentations. If EBITDA equals SDE minus replacement compensation C, then an SDE-based price P implies an EBITDA multiple P / (SDE − C). The result can be much higher than the advertised SDE ratio when owner labor is a large share of total earnings.

Price = SDE multiple × SDE
Managed EBITDA = SDE − required owner replacement cost
Equivalent EBITDA multiple = Price / managed EBITDA

For example, 3.0x SDE on $500,000 means a $1.5 million price. If replacement labor is $200,000, EBITDA is $300,000 and the equivalent ratio is 5.0x. A nominally lower Main Street multiple can therefore represent a similar or higher price relative to managed earnings.

Size tiers represent organizational differences

Larger companies often have management depth, diversified customers, stronger reporting, and access to more financing sources. These attributes can support higher valuation multiples because a smaller portion of earnings depends on one person or relationship and more buyers can evaluate the opportunity.

Size itself is not a guarantee. A larger business can have concentrated contracts, obsolete equipment, or weak margins. A small contracted service company can be more durable than a larger project contractor. The analyst should explain which features accompany size in the observed dataset rather than award a fixed premium for crossing a revenue threshold.

The language of tiers must also be defined. Main Street commonly refers to smaller owner-operated transactions, while lower middle market describes larger managed acquisitions, but neither term has one universal boundary. Some reports classify by deal price, others by EBITDA or revenue. A $3.8 million acquisition should not be assigned an institutional multiple solely because the broker calls it lower middle market.

The BizBuySell Q3 2026 report provides an example of observed size segmentation, but its reported cash-flow metrics require their own definitions. The broader Pepperdine research collection similarly needs respondent and size context before a statistic can be applied. Neither source authorizes an analyst to relabel a selected metric to suit the target.

Industry differences: explain the mechanism

A restaurant, machine shop, distributor, and alarm-services operator can earn the same EBITDA while converting it into very different cash. Restaurants can face leases, labor turnover, and discretionary demand. Machine shops require equipment replacement and technical capability. Distributors may finance inventory and customer credit. Service operators depend on technician capacity, licenses, and contract retention.

These differences affect both cash forecasts and the appropriate comparable set. They do not establish fixed industry multiples. The correct question is what buyers paid for similar earnings quality, reinvestment, transferability, and growth in a defined market period.

For Apex, inspection and monitoring revenue may recur, but installation revenue can be project-dependent. An alarm-monitoring account portfolio and a contractor with incidental monitoring can have different unit economics. Combining all revenue under one industry label risks paying a recurring-contract multiple for one-time work.

Fictional business	Earnings convention	Illustrative multiple	Implied price	Main economic question
Owner-run restaurant	SDE $250,000	2.5x	$625,000	Owner labor, lease, and maintenance
Local HVAC operator	SDE $450,000	3.0x	$1,350,000	Technician capacity and replacement management
Managed machine shop	EBITDA $700,000	4.5x	$3,150,000	Equipment reinvestment and customer mix
Contracted services firm	EBITDA $900,000	5.5x	$4,950,000	Retention, assignments, and recurring contribution

The numbers illustrate mechanics, not actual market quotes. A learner should be able to explain why any one of these businesses could deserve a lower or higher price after inspecting its facts.

Revenue multiples conceal margin assumptions

A revenue multiple can be useful when earnings are unstable or a specific industry prices a transferable customer base using revenue-related metrics. It remains an indirect statement about future margins and cash conversion. Two firms with identical revenue but different margins should not automatically receive the same value.

A company valued at 0.8x revenue with a 20% EBITDA margin is valued at 4.0x EBITDA because 0.8 / 0.20 = 4. A company at the same revenue multiple with a 10% margin trades at 8.0x EBITDA. The denominator conversion exposes the hidden profitability assumption.

For Apex's $4.8 million revenue and $800,000 normalized EBITDA, the $3.8 million price equals 0.7917x revenue and 4.75x EBITDA. Its EBITDA margin is 16.6667%. The ratios agree because they describe the same operating perimeter; no extra value arises from presenting the more attractive-looking ratio.

When comparing revenue metrics, determine whether they represent recognized sales, annualized recurring revenue, contracted annual fees, or collected customer payments. A project backlog is not recurring revenue, and gross billed equipment cost can include low-margin pass-through items. The economic quality of the revenue matters more than its label.

Capital intensity and the EBITDA illusion

Suppose two businesses each generate $800,000 EBITDA. Company A requires $80,000 annual maintenance CapEx and $20,000 additional NWC. Company B requires $250,000 CapEx and $100,000 NWC. Before tax and financing differences, A retains $700,000 after these investments while B retains $450,000.

At 4.75x EBITDA, both have the same $3.8 million price, but A's pre-tax post-investment yield is approximately 18.42%, compared with 11.84% for B. A comparable multiple needs to account for this cash-conversion difference, whether through selection, a valuation adjustment, or a DCF reconciliation.

Do not fix the problem by adding back depreciation and assuming CapEx disappears. EBITDA already excludes depreciation. The missing cash cost belongs in the investment forecast. A buyer can pay too much for a company that appears cheap on EBITDA because its equipment absorbs most of the earnings.

Apex's capstone assumes $80,000 maintenance CapEx and $20,000 annual incremental NWC. Those amounts require asset-condition and collection evidence. If the owner deferred fleet replacement, the first year's cash may be materially lower even when normalized EBITDA is correct.

Period consistency: LTM, run rate, and forecast

Last-twelve-month earnings include the most recent twelve months and help avoid comparing a partial year with a full year. A fiscal-year figure can be stale if the business changed substantially after year-end. A run-rate figure annualizes a defined current operating condition; it needs evidence and may be distorted by seasonality.

A seller may quote 4x projected EBITDA but compare that ratio with historical transaction multiples. If the projection assumes a new manager, price increases, and improved retention that have not occurred, the multiple is not cheaper simply because the forecast denominator is larger.

For Apex, the accepted $800,000 is normalized historical managed EBITDA, not the buyer's hoped-for future result. If an implemented pricing change supports an additional $50,000 annual profit, show a separate run-rate case with customer retention and implementation timing. Keep the historical benchmark intact so readers can assess execution risk.

The same discipline applies to a transaction's numerator. A maximum earnout headline paired with a forecast earnings figure can exaggerate both price and performance. Record actual or stipulated consideration, metric period, and the relationship between them rather than calculating a ratio from unrelated numbers.

Seller Traps & LOI Landmines: the shifting denominator.

A negotiation can begin at four times historical earnings and quietly become four times next year's optimistic earnings without anyone discussing a higher price. Put the exact earnings definition, period, accepted adjustments, and price basis in the valuation memo and commercial term sheet.

Reconcile price with the buyer's reservation value

A market range describes observed or inferred pricing. The buyer's reservation value describes the maximum acceptable economic commitment given cash generation, financing, required return, and alternatives. It can be lower than a seller's market-supported expectation.

At the $4.2 million ask, Apex costs 5.25x normalized EBITDA or 4.2857x SDE. At $3.8 million, the ratios are 4.75x and 3.8776x. The $400,000 concession can matter materially, but negotiating it does not cure unsupported retention assumptions or a financing shortfall.

Show a price-to-return and price-to-liquidity bridge rather than insisting one multiple is objectively correct. A strategic buyer might realize supported integration savings unavailable to a standalone acquirer. That buyer can have a higher reservation value, but must account for integration costs, execution, taxes, and timing.

A disciplined decision can therefore conclude that a company is well priced for another buyer but unsuitable for this one. That is not a failure of valuation. It is recognition that comparable price, intrinsic value, financing capacity, and investor objectives answer related but different questions.

Document a multiple recommendation that survives review

The final recommendation should identify the target earnings bridge, the comparable evidence, the chosen range, and the reasons the target sits within it. Describe concentration, management, recurring contribution, capital needs, and growth without inventing unsupported numerical premiums for each attribute.

Use sensitivities for both earnings and the multiple. A $50,000 EBITDA correction at 4.75x changes EV by $237,500. Moving the multiple 0.25x on $800,000 changes EV by $200,000. These two sources of uncertainty can be similar in size, so earnings diligence deserves at least as much attention as multiple negotiation.

Preserve rejected seller claims and excluded comps. The record should explain how the conclusion would change if replacement compensation or maintenance spending differs. The model is most useful when it allows another reviewer to revise one assumption without reconstructing the entire conversation.
