How to Evaluate a Business-for-Sale Listing Before Signing an NDA

Published

Most acquisition listings are written to generate inquiries, not to help a buyer make a complete investment decision. A useful first pass therefore has a narrow goal: determine whether the opportunity deserves more time.

You do not need a full diligence model to reach that decision. You need consistent definitions, a few calculated fields, and enough skepticism to separate missing information from bad information.

1. Confirm what the earnings number actually means

Listings commonly use SDE, EBITDA, adjusted EBITDA, cash flow, discretionary earnings, net income, or an undefined profit figure. These labels are not interchangeable.

Seller’s discretionary earnings (SDE) generally starts with business profit and adds back one owner’s compensation and certain discretionary or nonrecurring expenses. It is most useful for smaller businesses where the buyer expects to replace the working owner.

EBITDA measures earnings before interest, taxes, depreciation, and amortization. It does not automatically include the owner’s compensation as an add-back. A buyer who will need to hire management should account for that replacement cost.

Adjusted EBITDA includes seller-proposed adjustments. Some adjustments are reasonable. Others represent costs that will continue after closing. Treat every adjustment as a claim that needs support.

If the listing says only “cash flow” or “profit,” record the label exactly as published and avoid converting it into SDE or EBITDA. An attractive multiple built on the wrong earnings definition is not attractive.

2. Match the earnings figure to a period

An earnings number without a period is incomplete. Determine whether the figure represents the latest completed fiscal year, trailing twelve months, year to date, an annualized partial year, or a forecast.

Give the most weight to completed periods and clearly defined trailing-twelve-month results. Treat annualized and projected figures as separate information, not substitutes for actual performance. When the source does not disclose the period, mark it undisclosed.

3. Calculate the asking-price multiple carefully

The basic calculation is: Asking price ÷ reported earnings = asking-price multiple.

A $2.4 million asking price divided by $600,000 of SDE produces a 4.0x asking-price-to-SDE multiple.

That calculation is only comparable across listings when the numerator and denominator contain similar items. Check whether asking price includes inventory, working capital, real estate, vehicles or heavy equipment, excess cash, or assumed debt. If a $4 million asking price includes $1.5 million of real estate, the total-price multiple should not be compared blindly with an asset-light service business.

4. Look for evidence that earnings can transfer

A buyer is purchasing future cash flow, not the seller’s historical workload. Ask whether the business can continue producing earnings after the owner leaves. Positive signals include a manager or second layer running daily operations; company-held customer relationships; repeatable sales and estimating; transferable licenses and certifications; documented supplier relationships; and meaningful employee tenure.

Watch for listings where the owner handles sales, estimating, key accounts, scheduling, or technical work. Earnings may be real while transfer risk remains high.

5. Separate recurring revenue from repeat business

Recurring revenue comes from contracts, subscriptions, scheduled routes, monitoring agreements, maintenance plans, or another structure that causes revenue to repeat without a new sale. Repeat business means customers have returned historically. It is valuable, but different.

Ask what portion is contracted, how agreements renew, whether pricing can change, and how easily customers can cancel.

6. Check customer concentration

Ask for the percentage of revenue and gross profit from the top customer and top ten. Also consider concentration by industry, geography, referral source, supplier, salesperson, and contract type. Concentration is not always disqualifying, but it changes value and the evidence needed about retention.

7. Estimate the capital the business consumes

Reported earnings do not show every cash requirement. Consider vehicles, machinery, inventory, deposits, bonding, and seasonal working capital. For asset-heavy businesses, compare depreciation with maintenance capital expenditure and fleet age. For project businesses, examine cash needed to fund payroll and materials before payment. High SDE can overstate owner cash flow when reinvestment has been deferred.

8. Test the quality of the revenue base

Look for stable or improving gross margins, balanced customers and services, limited dependence on one-time projects, signed backlog, contract renewal history, and demonstrated pricing power. Determine whether growth came from repeatable operations, a temporary event, one customer, or aggressive underpricing.

9. Identify licenses and regulatory dependencies

Determine who holds required credentials, whether they transfer, how long approval takes, and what happens if a key person leaves. A profitable business can still be difficult to transfer legally or operationally.

10. Read the reason for sale as a diligence question

Retirement and succession are reasonable explanations and starting points for verification. Compare the stated reason with hiring, customer changes, financial trends, litigation, owner workload, and asset condition.

11. Distinguish missing information from a negative fact

Keep three categories: verified facts published by the original source; unknowns requiring clarification; and watch-outs that could affect value or transferability. This keeps the initial review honest.

12. Decide whether the next hour is justified

Use four outcomes: Advance for strong fit and enough information to request the package; Monitor for a credible opportunity with timing or one key fact unresolved; Hold when material information is missing or conflicting; and Pass when clearly outside the buy box or dependent on unacceptable assumptions.

A simple first-pass checklist

Before requesting confidential materials, record:

  • Asking price and what it includes
  • Revenue and financial period
  • Earnings amount, exact definition, and period
  • Asking price divided by the stated earnings measure
  • Customer and supplier concentration
  • Owner responsibilities
  • Management depth
  • Recurring or repeat revenue evidence
  • Required working capital and capital expenditure
  • Licensing or regulatory dependencies
  • Reason for sale
  • The three most important unanswered questions

FAQ

What is the difference between SDE and EBITDA?

SDE generally adds one working owner’s compensation and certain discretionary expenses back to profit. EBITDA excludes interest, taxes, depreciation, and amortization but does not automatically add back owner compensation. Preserve the exact definition used by the source.

How do you calculate the asking-price multiple for a business?

Divide asking price by the reported earnings measure and label the result with the same definition, such as asking price divided by SDE or EBITDA.

Is recurring revenue the same as repeat business?

No. Recurring revenue is supported by a contract, subscription, route, or maintenance agreement. Repeat business means customers returned historically without necessarily being obligated.

What should a buyer review before signing an NDA?

At minimum, confirm earnings definition and period, asking price and included assets, owner involvement, concentration, management depth, capital needs, licensing dependencies, and the most important missing information.
