- · Founders consistently overvalue their businesses by approximately 30 percent, driven by loss aversion and the endowment effect rather than any failure of character.
- · Realistic EBITDA multiples for Swiss and DACH micro-cap SMEs are materially lower than the large-cap benchmarks most founders reference.
- · Up to five standard EBITDA adjustments reduce the operating earnings figure before a multiple is even applied, shifting valuation by 15 to 30 percent.
- · The headline enterprise value on a term sheet is not what reaches the founder's bank account; a structured purchase-price bridge separates the two figures by a wide margin.
There is a predictable, well-documented gap between what a founder believes a business is worth and what a disciplined buyer will offer. Research by Sampford Advisors places that gap at approximately 30 percent — and in practice, it is frequently wider at the opening of a process than at the close. The gap is not a sign of irrationality. It is a structural consequence of how human psychology interacts with the singular financial event most founders will ever undertake.
For the majority of owner-managers in Switzerland and the broader DACH region, a business sale is both the largest transaction of their professional lives and the only one they will conduct without prior experience. That combination concentrates every cognitive distortion the behavioral finance literature has catalogued.
Two cognitive biases reliably appear in business-sale contexts, as Sampford Advisors documents in its analysis of the psychological dimensions of founder exits.
The first is loss aversion: the deeply human tendency to weight what is surrendered more heavily than what is gained. A founder does not merely sell a revenue stream. The act involves relinquishing control, a daily sense of purpose, and an identity that has been constructed over years or decades. The financial gain — liquidity, freedom, security — is real, but psychologically it registers with less force than the loss of what has been built.
The second is the endowment effect: owners systematically ascribe higher value to assets they hold than the open market will support. A business that has been managed, improved, and worried over for fifteen years feels categorically different from the outside than it does from the inside. That felt difference translates, reliably, into a valuation premium that buyers have no mechanism to price.
Neither bias is a personal failure. Both are documented across decades of behavioral economics research. What matters, from a transaction standpoint, is that they are predictable — and therefore addressable.
Dean Dorton M&A Advisory articulates the divergence with precision: sellers focus on what the business has achieved; buyers focus on how reliably those results will continue. A record revenue year, a market-share gain, an operational system the founder designed and optimized — these carry weight in the founder's mental ledger. In a buyer's model, they matter only to the extent they are durable under new ownership.
As Dean Dorton observes: "The market pays for durability, not optimism. Risk doesn't always kill a deal — but it often compresses the multiple, or significantly alters the payment terms and considerations in a way where a seller will bear a substantial risk post-close."
A business generating CHF 1.5 million in EBITDA with a loyal customer base may appear, from the founder's perspective, to warrant a multiple of 8.5x to 9.5x. A buyer examining the same business notes whether the founder personally manages the three largest accounts, whether the top three customers represent more than 30 percent of revenue, and whether any second tier of leadership exists. Each of those factors compresses the multiple, not arbitrarily, but because they represent the measurable cost of transfer risk.
Current market data from Deal Origination's DACH EBITDA multiples database (Q2 2026) provides sector-level benchmarks that illustrate the structural gap with considerable clarity.
In IT Services and Managed Services, micro-cap businesses (revenue below CHF 5 million) transact at 5.7x to 6.8x adjusted EBITDA. Founders in this sector frequently anchor to large-cap comparables, which trade at 7.8x to 10.2x, on the basis of peer references or market commentary. The difference is not an injustice — it is the arithmetic of a size discount (1.0x to 2.5x), an illiquidity discount applicable to owner-managed businesses, and a concentration penalty where the business is commercially dependent on the founder's relationships.
In Mechanical Engineering and Manufacturing, micro-cap multiples range from 3.5x to 4.5x, while small-cap businesses (CHF 5 to 50 million in revenue) achieve 4.6x to 6.0x. Large-cap sector medians at 5.6x to 7.1x anchor founder expectations, leading to understandable friction when buyers present offers in the 4.2x to 4.8x range for a founder-run operation.
In Building Services, HVAC, and Fire Safety, micro-cap businesses transact between 4.5x and 6.0x, with recurring maintenance revenue supporting the upper bound and pure project work sitting at the lower end. A founder with 45 percent of revenue from maintenance contracts has a defensible case for the higher multiple — but only if those relationships are demonstrably transferable without the founder's personal involvement.
The pattern is consistent across sectors: founders compare to best-in-class or peak-market transactions; buyers price to risk-adjusted, transferable earning power. The gap is a function of reference point, not bad faith on either side.
Before any multiple is applied, the EBITDA figure itself must be normalized. This is where a significant portion of the overvaluation gap becomes quantifiable. According to Deal Origination's analysis of typical DACH Mittelstand transactions, five adjustments appear in 80 to 90 percent of deals and collectively shift the EBITDA base by 15 to 30 percent.
Founders frequently draw salaries set for tax efficiency rather than market equivalence, either above or below what a replacement managing director would cost. Buyers restate this to market rate, typically CHF 150,000 to CHF 250,000 annually for small businesses. Where a founder draws CHF 320,000 and the market rate is CHF 180,000, the add-back is CHF 140,000. At a 6.0x multiple, that single adjustment represents CHF 840,000 in enterprise value.
Owner-managers who hold operating real estate in a separate entity frequently charge the operating business rent that diverges from market rate by 30 to 60 percent. Buyers normalize to market appraisal. A business paying CHF 240,000 annually where market rate is CHF 150,000 carries a CHF 90,000 add-back — worth CHF 540,000 at 6.0x.
Pandemic relief payments, litigation settlements, gains on asset disposals, and amortization from prior acquisitions are stripped from the EBITDA base because they do not reflect the sustainable, recurring earnings that underpin any multiple.
Payroll entries for spouses, children, or partners who do not carry identifiable operational functions are eliminated in due diligence without exception. Where CHF 220,000 in family payroll contains CHF 140,000 attributable to no defined function, the adjustment at a 7.0x IT services multiple is worth CHF 980,000.
Cash holdings beyond normalized working-capital requirements, investment securities, and surplus real estate are valued separately and accrue directly to seller proceeds outside the operating-business multiple. A company holding CHF 2.8 million in cash against an operating requirement of CHF 600,000 sees CHF 2.2 million recognized as additional proceeds — a meaningful figure that founders who focus only on the operating multiple can inadvertently discount.
A founder who enters a sale process with unadjusted EBITDA and expectations built upon it will encounter these adjustments during buyer due diligence, under time pressure, at a moment of heightened emotional investment. Encountering them privately, two years in advance, is a materially different experience.
Even when EBITDA has been normalized and a multiple agreed, the enterprise value stated on a term sheet is not the amount that settles into the founder's account. Five structural components sit between the headline figure and net proceeds, as documented in Deal Origination's analysis of DACH purchase-price bridge mechanics.
Net debt is deducted from enterprise value, with surplus cash added back. A working capital adjustment settles deviations from the normalized working capital defined in the purchase agreement — these swings commonly range from CHF 100,000 to CHF 500,000 in either direction. Earn-out components, typically representing 10 to 25 percent of total purchase price, are paid over 12 to 36 months contingent on performance targets the seller bears the risk of missing. A vendor loan (Verkäuferdarlehen) requires the seller to finance 5 to 15 percent of the purchase price as a subordinated instrument, at terms of 5 to 7 years and interest rates of 4 to 7 percent. Additional working capital and price adjustment mechanics can shift the final figure by a further 10 to 20 percent of the headline.
The arithmetic is instructive. An SME with adjusted EBITDA of CHF 1.8 million, valued at 7.0x for an enterprise value of CHF 12.6 million, with CHF 1.4 million in net financial debt, CHF 600,000 in surplus cash, a CHF 2 million earn-out payable over 24 months, and a CHF 1 million vendor loan delivers approximately CHF 8.8 million to the seller at closing. The real multiple received at closing is 4.9x EBITDA — not 7.0x. Founders who anchor to the headline multiple without understanding the bridge are structurally positioned for disappointment.
The gap between emotional value and market value is not immutable. It narrows considerably when founders act with the appropriate lead time, typically two to three years before a planned transaction.
Normalizing the EBITDA structure under the founder's own control, rather than under buyer pressure during due diligence, eliminates the adversarial dynamic from the adjustment process. Documenting payroll functions, restating owner compensation to market rate, and segregating non-operating assets costs nothing in negotiating power and provides clarity on the realistic valuation range well before any process begins.
Reducing customer concentration is among the highest-return actions available to any founder preparing for sale. A single customer representing more than 20 percent of revenue is a quantifiable multiple drag. Diversifying that exposure over two to three years can shift the applicable multiple more meaningfully than any financial restatement.
Building a second tier of operational leadership addresses what is, across sectors, the most consistent valuation discount: owner-centrality. Where key customer relationships and technical knowledge transfer with the founder, buyers price that risk. Where they demonstrably do not, the discount disappears.
Finally, defining personal financial sufficiency before a process begins — while calm and analytical, not in the final hours of a negotiation — allows founders to separate the personal question of whether to sell from the transactional question of on what terms. Founders who conflate the two decisions are more likely to anchor on a target price the market will not support and to experience the inevitable recalibration as a defeat rather than as market information.
The 30 percent overvaluation gap is not a DACH-specific anomaly, nor a reflection of founder naivety. It is a predictable, well-documented phenomenon that affects owner-managers across geographies and sectors. In the Swiss SME context, where founder-managed businesses dominate the Mittelstand and generational transitions are accelerating, the practical consequences of unaddressed overvaluation are material — both for individual outcomes and for transaction completion rates.
Founders who enter a sale process with normalized EBITDA figures, a realistic understanding of applicable multiples, and a clear model of the purchase-price bridge are not merely better informed. They negotiate more effectively, engage more constructively with buyer concerns, and tend to walk away from closing with expectations that were met rather than revised downward at the last possible moment.
The most durable exits are rarely those that achieve the highest headline number. They are those where the founder understood what was being measured, prepared for how the process would unfold, and made a decision grounded in financial reality rather than in the entirely human tendency to overvalue what belongs to us.
