How DSOs Value Dental Practices: Test the Buyer's Case

How DSOs value dental practices: unpack the buyer's case

Ask which business the DSO is pricing and what it expects to earn. Then ask what must change to achieve that result. A quoted multiple gives you a ratio. To assess the number, ask for the earnings definition, the period, the included assets, and the operating assumptions behind it. Then examine the cash the proposed owner expects to receive.

The ADA's valuation guidance stresses defining what is being bought or sold and when. That scope should be clear before comparing conclusions. (ADA valuation scope.)

This guide shows how to examine a specific buyer's economic case and a price ceiling under supplied assumptions. It does not report a current DSO multiple range or claim that every DSO uses the illustrated model. Begin with the practice valuation guide for the wider valuation process. Use the SDE and seller-net guide to reconcile historical owner earnings and closing proceeds.

Keep those tasks separate. Accurate historical earnings are an input to a forward analysis, not a complete answer about future cash. The price a buyer can support also differs from the seller's proceeds under an offer. Rebuilding the same earnings adjustment schedule will not answer what the buyer expects to change after ownership transfers.

Put every earnings label beside its actual definition

The SEC's non-GAAP guidance warns that excluding normal recurring cash operating costs can mislead and that similarly labeled measures may not be comparable. This is public-company reporting guidance, not a rule prescribing private dental acquisition terms. (SEC non-GAAP guidance.)

Ask the buyer to identify the exact measure used in its proposal. Record whether it describes completed operations, an annualized partial period, or a future budget. Obtain a bridge where the proposal changes the seller's reported figures. A spreadsheet heading is not enough if another team uses the term for a different result.

Dentalcorp's August 2025 Canadian issuer release describes acquisition-related pro forma practice earnings based on budgets and separately presents a measure after rent. It cautions that budgeted amounts may differ from actual results. This is a named issuer's disclosure, not evidence of a U.S. dental market multiple. (Dentalcorp Q2 2025 definitions.)

Use that example to request the buyer's definitions, not to substitute one company's accounting presentation for your own deal. Determine where premises costs, required staffing, central support, and future spending appear. If the buyer provides more than one version of earnings, retain all versions and the reason each exists. The objective is a comparison that can be checked, not selecting whichever figure supports the preferred price.

Separate the existing business from proposed improvements

In his NYU acquisition-valuation materials, Aswath Damodaran distinguishes standalone value from value created by combining businesses. His process examines the form and timing of expected benefits, then compares values with and without them using discounted cash flows. These are general valuation concepts, not evidence that a particular DSO can achieve an improvement. (NYU acquisition valuation.)

Ask the buyer to name each proposed change. For a task that moves to a central team, ask what work ends locally and what work starts elsewhere. Show the net cash effect. A growth plan should identify the resources, approvals, and demand evidence it depends on. An empty room does not establish that extra treatment can be delivered profitably.

Keep benefits that the practice could achieve on its own separate from benefits that require this buyer. That distinction helps the seller assess a claim that only one acquirer can support the offer. It also helps the buyer avoid treating a general opportunity as a resource it already controls. Neither category produces an automatic premium without an economic case.

For each change, record the start date and the proof needed to put it in the base model. A benefit that depends on an unsigned agreement or an unfilled job can remain in a separate case. The seller can then discuss the evidence and allocation of risk without endorsing an unsupported forecast as established performance.

Build a cash forecast before solving for price

Use a forecast that makes its cash boundary explicit. The case below supplies annual cash after paying for all required clinical and office work, premises, and cash taxes. It also accounts for equipment spending and changes in working capital. It is before purchase financing. No amount is inferred directly from EBITDA, and no expense is removed merely because the owner changes.

Your accountant should build the actual forecast from the practice records and the proposed operating plan. Identify who prepared each input and which supporting document allows it to be checked. If the cash forecast already includes an improvement, do not add its value again as a separate premium. If a setup cost occurs at closing, do not also deduct it from later cash unless there are separate payments.

The table is a review tool for the particular proposal. It does not assign market costs, dictate a valuation standard, or tell a lender what to approve. A model may serve one purpose well and still fail to meet a different legal, tax, or appraisal need.

Worked example: a buyer-specific price ceiling

Assume a buyer is considering an all-cash acquisition of the operating business, free of acquisition debt in this model. All numbers are invented U.S. dollar inputs. The annual cash amounts, on the boundary defined above, are $180,000, $200,000, and $220,000 at the ends of years one, two, and three. The buyer also pays a separate $60,000 integration cost at closing.

Assume the remaining operating business is worth $1,100,000 at the end of year three, after that year's operating cash. This terminal amount is a supplied net realization value, already after any realization costs and taxes assigned to it. It is not a forecast sale, an assumed DSO recapitalization, or a multiple taken from market data. No building or other separately priced asset is included.

The supplied required annual return is 10%. This is a teaching assumption, not a current financing rate or a recommended return. Discount each year-end amount by 1.10 raised to its year number. Add the discounted operating cash and terminal amount, then subtract the closing integration cost. That gives the maximum price with zero net present value under this exact case.

The unrounded calculation produces about $1,260,661. Each row is rounded. Adding those rows may differ from the rounded total by a dollar. Paying that ceiling would leave no net present value above the assumed return within this model. A buyer can choose a lower offer; the seller need not accept it. The calculation establishes neither negotiating power nor a guaranteed investment outcome.

The model treats the purchase price as a closing cash payment for the defined operating business. It does not value a deferred payment, a seller note, rollover equity, or an earnout. If an actual offer includes those components, analyze their timing and conditions separately. The DSO offer comparison calculator helps organize that later seller-side comparison.

Test operating cash and remaining value separately

First, change only the terminal input to $880,000, a 20% reduction from the supplied $1,100,000. Keep annual operating cash, timing, the required return, and integration cost unchanged. The price ceiling falls to about $1,095,372. The reduction is about $165,289, which is the $220,000 terminal change discounted for three years.

For a separate test, restore the original terminal amount and reduce each annual operating-cash input by $20,000. The amounts become $160,000, $180,000, and $200,000. The ceiling becomes about $1,210,924, or $49,737 below the base. This tests only the forecast-period cash effect. It does not claim that weaker operations would leave real terminal value unchanged.

These isolated changes show which assumptions deserve more attention. In a real forecast, lower operating cash could also affect the remaining business value. Model that linked effect as an additional case when the facts warrant it. Do not present the isolated operating test as a complete downside analysis, and do not treat any result as a probability-weighted forecast.

The important discussion is what supports the terminal input. Ask what operating condition exists at that point, what ongoing spending it requires, and how the valuation professional derived the remaining value. A short forecast period does not remove uncertainty after that period; it places that uncertainty into the terminal assumption.

Decide what evidence could change the buyer's ceiling

Sort open matters by their connection to the forecast. A disputed historical classification may change the starting cash estimate. A verified service contract may change the timing of an integration saving. A facility limitation may change the work that can be performed. The response should address that link rather than applying an unexplained percentage reduction to the price.

Ask the buyer to explain a revised conclusion against the prior model. Which fact changed, which input moved, and which period did it affect? Preserve both versions and the evidence behind the revision. A lower number can reflect a corrected fact, a different plan, or a change in the buyer's preferences. Those are different negotiation discussions.

The seller need not agree with every buyer assumption. Where evidence supports another view, provide it through the authorized review process and ask for a consistent recalculation. Where the parties still disagree, record the difference. Do not manufacture certainty merely to make the numbers converge.

For a buyer, keep the valuation decision separate from funding availability. Debt terms can affect the acquisition's financing and owner cash without proving that the operating forecast is sound. Use the dental practice financing guide to organize a funding discussion after the business scope and cash assumptions are clear.

Protect the seller while testing buyer-specific claims

Initial outreach should remain seller-blind, omitting the practice and owner names, exact address, financials, and staff details. An early discussion can describe a broad acquisition mandate without releasing a recognizable operating profile. Obtain an NDA before an authorized buyer receives identifying information, then tie each disclosure to the question being reviewed.

Time staff participation to their actual duties. A finance employee may need to reconcile a report, or a manager may need to verify the workload behind a proposed saving. Decide who authorizes that participation, what information the person needs, and who answers questions about the transaction. Do not require all staff to remain uninformed until closing when necessary work depends on them.

Commercial confidentiality is separate from patient privacy, clinical authority, required notices, and material authorized diligence. A buyer's request for proof of a forecast does not by itself authorize access to patient information. Use the appropriate advisers to resolve those boundaries while making relevant authorized business evidence available for a meaningful review.

Common mistakes when interpreting a DSO valuation

One mistake is repeating a multiple without its denominator or payment terms. Another is treating a future budget as completed performance. Keep the earnings definition and its period visible. A new label should not quietly become a new value.

Another error is counting the same benefit in forecast cash and in an added premium. Ask the analyst where each claimed benefit enters the calculation. If it is already included, another value adjustment needs a separate reason. The same check applies to integration spending that might otherwise be deducted twice.

Finally, avoid treating the buyer's ceiling as the seller's take-home amount or a prediction of the winning bid. The seller still needs to compare actual offers, conditions, work duties, and payment risk. Use the DSO guide for that broader choice and keep a clear record of which question each analysis answers.

Summary: require a price supported by a defined case

A useful DSO valuation discussion connects defined earnings, future operating cash, needed spending, and remaining business value. Separate evidence about the practice from improvements that depend on a particular buyer. Test important assumptions independently, then examine linked changes where the facts require them.
