Reconcile the owner before you compare the earnings

SDE and EBITDA differ before a multiple enters the conversation

Seller's discretionary earnings and EBITDA describe different earnings bases. Under the cited IBBA definition, SDE includes one owner's compensation, benefits, qualifying personal expenses, and specified nonrecurring or nonoperating items. SEC staff describes EBITDA as net income before interest, taxes, depreciation, and amortization. The exact bridge, not the acronym, determines what the figure contains. ¹²

Keep three labels separate. Reported EBITDA removes only interest, income taxes, depreciation, and amortization from the starting net income used here. Adjusted EBITDA applies additional, named normalization items. SDE then asks a different owner-operator question by including one working owner's compensation and specified owner-related items. A workbook that calls all three “cash flow” erases the decision.

SEC guidance applies to public-company non-GAAP disclosure, not a private-company sale. Its terminology is still a useful control: when a measure is calculated differently from EBITDA, give it a distinguishing title and reconcile it to the source statement. That discipline prevents a proposed add-back from disappearing inside the acronym. ²

The IBBA glossary standardizes brokerage language, but it does not make every adjustment acceptable to every buyer. It also does not supply a valuation method or multiple. Treat the definition as the first column of the workpaper, then make the company's actual records, operating model, and intended use visible. ¹³

A mechanical calculation remains a calculation. IVS places purpose, basis, data reliability, model responsibility, documentation, and limitations around a valuation; AICPA's toolkit likewise says its calculation materials do not establish a preferred practice and leave responsibility with the practitioner. The earnings bridge informs a valuation discussion but does not become the conclusion. ³⁶

The owner-role map is the missing schedule

Begin with work, not compensation. List what the owner actually does: selling, estimating, producing, managing people, approving pricing, holding relationships, signing regulated work, handling finance, or covering emergencies. Then record time, seasonality, backup coverage, and the employee or outside provider who could assume each duty.

Current pay does not answer replacement cost. An owner may be overpaid, underpaid, paid through several accounts, or compensated partly through benefits and distributions. Replacement cost asks what the future operating model would need to spend to cover the required work. It may involve one role, several roles, or a redesign rather than one new chief executive.

For S corporations, IRS reasonable-compensation guidance examines the shareholder's services, time, experience, source of receipts, comparable pay, and compensation arrangements. That is a tax-specific inquiry, not a transaction replacement-salary formula. The practical lesson is narrower: the title “owner” is not enough evidence for either calculation. ⁵

Keep the tax workpaper and the transaction workpaper separate. The first supports federal compensation treatment for the relevant entity and period. The second supports the hypothetical cost of running the company after the owner steps away. Qualified tax and valuation professionals may use overlapping records, but the questions and conclusions are not interchangeable.

• Write each recurring owner duty in observable terms.
• Record weekly and seasonal time by duty.
• Identify existing employees who already cover part of the role.
• Separate wages benefits distributions and personal expenses.
• Source replacement cost by role geography and required experience.
• Preserve tax classification as a separate professional workstream.

One fictional company exposes the owner-cost difference

Hypothetical example — not market evidence, a valuation conclusion, or a forecast. Harbor Field Services is fictional. Every company fact, amount, adjustment, replacement-cost assumption, and result below was created solely to demonstrate the reconciliation.

Start with fictional net income of $480,000. Add $75,000 of interest expense, $40,000 of income taxes, $100,000 of depreciation, and $25,000 of amortization. Reported EBITDA is $720,000. No owner or normalization decision has entered yet; this subtotal follows the article's stated EBITDA construction. ²

Next, add a fictional $30,000 nonrecurring legal expense, subtract $10,000 of nonoperating income, add $260,000 of working-owner salary, and add $20,000 of documented owner-specific benefits. SDE is $1,020,000 under the disclosed hypothetical treatment. The illustration does not claim that a buyer would accept any line. ¹

To show an adjusted EBITDA basis for a managed operating model, begin with the same reported EBITDA and the same fictional normalization lines. Add back the owner's $260,000 salary and $20,000 of owner-specific benefits, then subtract $180,000 for the fictional cost of covering the required management work. Adjusted EBITDA is $840,000.

The $180,000 gap between fictional SDE and fictional adjusted EBITDA is exactly the replacement-management assumption. It is not a scale premium, market rule, or value conclusion. If the duty map supports two hires or more retained owner work, the bridge changes. If a buyer performs the role, its economics change again.

SDE can be translated to an adjusted EBITDA basis, but there is no reliable fixed conversion. Start with the same source period, reverse owner compensation and owner-specific items line by line, add the evidenced cost of replacing the owner's required work, and preserve any other normalization differences. The result remains an assumption-led reconciliation, not a valuation conclusion. ¹³

Reconcile in both directions. Building from net income catches omitted statement lines. Translating SDE back to adjusted EBITDA tests whether replacement cost and other adjustments were counted exactly once. If the two paths do not arrive at the same subtotal, stop before discussing a multiple and find the broken line.

An adjustment needs a record, a reason, and a counterfactual

Create one row for every proposed adjustment. Record the source account, amount, period, invoice or payroll support, business purpose, recurrence, and proposed treatment. Then state the counterfactual: what expense or income would exist under the future operating model if this line were removed?

A personal label is not enough. A vehicle, insurance premium, family payroll item, travel charge, or club fee may contain business and owner-specific portions. Preserve the invoice, policy, payroll record, and business-use analysis. Split mixed items rather than adding back the entire account because its name sounds discretionary.

A “one-time” label is also incomplete. State the event, why it is outside expected continuing operations, whether related costs or insurance recoveries exist, and whether another occurrence is already visible. IVS emphasizes data provenance and input reliability; SEC reconciliation guidance similarly makes the nature of reconciling items visible in its public-company context. ²³

Test downward adjustments with the same care. Nonoperating income, an owner role that is not fully recorded, deferred maintenance, an under-market family salary, or a cost that moved below the chosen starting subtotal can reduce normalized earnings. A credible schedule is not an add-back hunt; it is a complete bridge.

Finally, keep period consistency. Use the same trailing or fiscal period across the source statement, payroll, tax return, adjustment ledger, and comparison. If a proposal uses a different period, show a separate bridge. Do not blend a current revenue period with a prior-year expense base or use a run-rate adjustment without exposing the assumption.

• Tie the amount to the general ledger and statement.
• Attach invoices payroll reports or contract support.
• State why the item recurs or does not recur.
• Show the future operating-model counterfactual.
• Record related income costs and offsets together.
• Apply the same test to upward and downward adjustments.

Choose the earnings basis from the work after closing

Do not choose SDE or EBITDA from an unsupported revenue or earnings threshold. Ask who will perform the owner's work after closing and which costs remain in the company. The answer can differ among an owner-operator, an independent sponsor, a strategic acquirer, or a managed platform even when the historical statements are identical.

SDE can frame the economic benefit available to one active owner when that owner will perform the disclosed role. It does not mean every dollar is distributable cash. Capital spending, working capital, debt service, taxes, and other cash needs remain outside the acronym unless the specific calculation says otherwise.

Adjusted EBITDA can frame operations after a defined management-cost assumption. It is useful only when the owner-role add-back and replacement-cost deduction are both visible. Removing the owner salary without funding the work turns transition risk into an earnings increase on paper.

A strategic buyer may model synergies, duplicated costs, or a different organization. Keep those buyer-specific changes outside the company's stand-alone adjusted EBITDA until the proposal labels them separately. That separation lets the seller distinguish evidence about the company from economics unique to one buyer.

Ask for the exact denominator in every indication, offer, lender model, or advisor discussion. “EBITDA” may mean reported EBITDA, adjusted EBITDA, covenant EBITDA, or a buyer-defined measure. The written bridge and operating assumptions matter more than the label.

Match the earnings denominator to the value numerator

A multiple is a relationship, not a standalone fact. CFA Institute describes enterprise-value multiples as relating the value of the entire enterprise across capital sources to an entire-company measure such as EBITDA. That public-market framework does not supply a private-company multiple, but it makes the alignment question unavoidable. ⁴

Before comparing two indications, write four fields above each calculation: value numerator, earnings denominator, measurement period, and adjustment policy. Enterprise value divided by adjusted EBITDA is not directly comparable with owner proceeds divided by SDE. A shared “x” symbol does not make the economics equivalent.

Use the enterprise-to-equity bridge after the earnings denominator is reconciled. Debt, cash, working capital, expenses, escrow, contingent value, and taxes do not become earnings adjustments merely because they affect what an owner may ultimately receive. Keeping the value bridge separate prevents one disagreement from being counted in both the numerator and denominator.

Use the value bridge to connect enterprise value to equity purchase price and closing cashwithout hiding debt cash working capital or payment terms inside earnings.

Comparable evidence also needs a matching definition. A transaction multiple based on SDE should not be applied to EBITDA, and an EBITDA multiple should not be applied to SDE, without rebuilding the numerator, denominator, transaction perimeter, and evidence population. This guide deliberately supplies no market multiple or “typical” range.

If two advisors or buyers present different values, translate both to one common earnings basis before treating the gap as a pricing disagreement. The translation may reveal that the apparent difference comes from owner replacement cost, period selection, accepted adjustments, or the value basis—not appetite for the company.

Build a workpaper another person can challenge

Assemble the income statement, general ledger, tax return, payroll register, owner-benefit detail, debt and interest schedule, fixed-asset depreciation, amortization schedule, and support for every normalization item. Keep sensitive records in the controlled deal file, not a public form.

Give the workbook four visible subtotals: source net income, reported EBITDA, adjusted EBITDA, and SDE. Every line needs an amount, sign, period, source, rationale, owner, and status. Keep proposed, supported, disputed, accepted, and removed adjustments distinct; do not silently overwrite the original schedule.

Add an owner-role tab. Connect each duty to current coverage, transition plan, proposed replacement, evidence source, and estimated cost. Mark the cost as a hypothetical operating assumption until the responsible professionals and transaction counterparties address it. The workpaper should make disagreement easy to locate, not make uncertainty disappear. ³⁶

Use the earnings-quality guide to test add-back evidence and the valuation-method guide to keep the earnings input separate from the selected method. Then connect the chosen denominator to the enterprise-versus-equity bridge before reading a headline value as owner proceeds.

After the workpaper reconciles return to the valuation departmentto place the earnings basis inside the broader owner decision.

When the bridge is ready, the private valuation path can use the organized inputs without treating them as verified merely because they were entered. A confidential owner intake can also frame the next conversation without uploading sensitive source records. The useful output is a traceable question set, not a more confident acronym.

Use the organized bridge to continue to the private valuation pathwithout treating entered information as automatically verified.

Or use the owner intake to frame a confidential owner conversationwithout sending sensitive records through the public site.

• Preserve the untouched source statement and period.
• Label reported EBITDA adjusted EBITDA and SDE separately.
• Give every adjustment a record rationale and owner.
• Inventory owner duties before estimating replacement cost.
• Reconcile from net income and back from SDE.
• Match the final denominator to the value numerator.
• Keep disputed lines visible through the next review.
