The value of a company is not a single figure set in stone. It is an estimate that varies depending on the chosen method, the economic context, and the profile of the buyer or investor. Knowing whether this estimate reflects reality requires understanding what is being measured, how it is measured, and which elements escape traditional calculations.
Company Value and Sale Price: A Technical Distinction to Master
Before judging whether a valuation is fair, it is necessary to separate two often-confused concepts. The theoretical value of a company results from calculations based on objective data: assets, profitability, projected cash flows. The price, on the other hand, comes from negotiations between the seller and the buyer.
A buyer may agree to pay above the calculated value because they identify synergies with their own business. Conversely, an urgent sale or a depressed market can cause the price to drop well below the estimated value. The gap between the two does not necessarily indicate an evaluation error: it reflects a power dynamic and context.
To delve deeper into this topic, information on La Revue de l’Entreprise details situations where this gap becomes a warning signal.
A common pitfall is to confuse the result of a single method with “the” real value. Any serious evaluation crosses at least two approaches to define a range, not a fixed amount.
Valuation Methods: What Each Captures and What It Ignores
Three main families of methods coexist. Each sheds light on a different aspect of the company, and each has blind spots.
Asset-Based Approach (Adjusted Net Asset)
This approach adds up what the company owns (real estate, equipment, inventory, cash) and subtracts its debts. The result gives the adjusted net asset, a snapshot at a given moment.
This method works well for companies with a strong tangible component. However, it underestimates service or technology companies, whose value relies on intangible assets that are difficult to record on the balance sheet: know-how, customer portfolio, brand.
Market Multiple Approach
A coefficient (multiple) is applied to a financial indicator, often EBITDA. This multiple comes from comparable transactions in the same sector. The choice of multiple depends on the sector and the size of the company, making comparison tricky for atypical SMEs or those positioned in niches.
The main risk: using a generic multiple found online without verifying that it corresponds to companies with a truly similar profile.
Discounted Cash Flow (DCF)
This method projects future cash flows and discounts them to their present value using a discount rate. It is considered the most rigorous theoretically, but it relies entirely on growth and risk assumptions.
Changing the discount rate by a few points can significantly alter the valuation. A DCF evaluation is only reliable if the underlying assumptions are explicitly documented and tested against alternative scenarios.
Discount Factors That Traditional Methods Do Not Capture
The three approaches above rely on accounting and financial data. However, several qualitative elements can diminish the real value during negotiations:
- Dependence on the leader: if client relationships, technical decisions, and strategy rely on a single person, their departure weakens the entire structure. Buyers systematically apply a discount in this case.
- Concentration of the customer portfolio: when one or two clients represent the majority of revenue, the risk of a sudden loss of income lowers the valuation.
- Absence of formal contracts: business relationships based on verbal trust, without renewable written commitments, reduce visibility on future revenues.
- Opaque internal organization: undocumented processes, poorly maintained accounting, or ongoing disputes complicate the acquisition audit and foster distrust.
These factors do not appear in any mathematical formula. They emerge during the pre-sale audit and can create a significant gap between the initial valuation and the final offer.
ESG Performance and Valuation: A Criterion That Has Become Concrete
The Omnibus I directive of February 24, 2026, raised the thresholds for CSRD applicability: sustainability reporting now only concerns companies exceeding 1,000 employees and €450 million in net revenue simultaneously. Many mid-sized and large SMEs thus fall outside the legal scope.
Exiting the regulatory perimeter does not eliminate the pressure, however. Large account clients, banks, and investors continue to demand ESG data for their own compliance obligations and capital allocation decisions. A SME unable to document its environmental and social performance risks being excluded from certain tenders or facing less favorable financing conditions.
The impact on valuation is direct: a company deemed unfinanceable or not integrable into an ESG value chain loses value, even if its financial results are solid. This criterion, absent from traditional valuation methods, deserves to be integrated into any realistic estimate.
Cross-Referencing Results to Ensure Reliable Evaluation
One method provides a viewpoint. Two or three methods applied simultaneously outline a corridor of values. If the results converge, the range is credible. If the gaps are wide, it signals either poorly calibrated assumptions or a company profile that standard models struggle to capture.
Engaging an independent expert (valuation specialist accountant, transmission consulting firm) allows for confronting the results with knowledge of the local and sectoral market. The evaluation also gains credibility in front of a buyer or investor if it has been conducted by a third party.
The best way to know if the estimated value is fair is to test it: compare the obtained range with market feedback, initial discussions with potential buyers, or the conditions proposed by financiers. A valuation that does not withstand this contact deserves to be revised, not defended.
