What Does Professional M&A Advisory Deliver — And Do I Really Need an M&A Advisor for My Business Sale?

For most owners, selling a company is not an everyday matter but a once-in-a-lifetime event. Accordingly, the uncertainty about finding the right path is considerable. One of the central questions is: Should I engage an M&A advisor — or is that ultimately just an expensive luxury that costs more than it delivers?

The good news: both practical experience and academic studies provide a clear answer. Professional advisory pays off in the vast majority of cases. Because it not only increases the purchase price, but also the likelihood that the deal actually closes. And it ensures better contractual terms, which translate into real money for sellers.

What Do the Data Say?

To answer this question not just from gut instinct, it is worth looking at the facts. A comprehensive study by the University of Tilburg and the University of Heidelberg evaluated several decades of M&A transactions. The result is unambiguous: sales in which a sell-side advisor was mandated achieved significantly higher prices and acquisition premiums than those without an advisor. The likelihood of a deal actually closing also increases noticeably when a professional advisor is involved on the seller's side.

Particularly interesting: the researchers refuted the possible objection that "good companies" simply engage advisors more often. Through sophisticated statistical methods — including matching procedures and instrumental variable approaches — they were able to show that the effect is genuinely causal, i.e. it arises directly from the use of the advisor.

Industry reports for the mid-market also confirm the trend outside of academia. There, additional proceeds of between 6 and 25 percent are regularly cited when a professional M&A advisor is engaged.

In other words: the probability that advisory pays for itself is very high.

Why Does an M&A Advisor Increase the Purchase Price?

The reasons are quickly explained. A business sale is not a simple handshake deal, but a highly complex process in which many variables determine outcomes worth millions.

A decisive point is process design. An advisor organises the sale in a way that creates competition — either in the form of a structured auction or through so-called "negotiauctions", in which potential buyers are already placed in competition with one another in advance. This competition almost always leads to higher prices.

Added to this is access to the buyer universe. An experienced advisor opens doors that business owners often cannot reach on their own. This applies not only to known competitors, but also to international corporations and private equity investors. The latter in particular are currently sitting on enormous "dry powder" — capital that needs to be invested. This investment pressure can translate directly into a higher willingness to pay.

A further benefit lies in the professional preparation of information. Those who enter the market without thorough preparation risk buyers detecting risks and demanding discounts. A good advisor ensures that financial figures are backed by a Quality of Earnings report, that forecasts appear realistic yet attractive, and that the company's equity story is articulated clearly and compellingly. This reduces uncertainty — and uncertainty almost always costs money in an M&A process.

And finally there are the negotiations themselves. Whether it concerns the definition of net debt, working capital adjustments or the structuring of earn-outs: this is often where the difference between the agreed purchase price and what the seller actually receives is decided. Experienced advisors know the margins, deploy the right arguments and use instruments such as Warranty & Indemnity Insurance to reduce escrows. The result: more net proceeds for the seller.

Not to be forgotten: an advisor takes over the management of the entire transaction process. Data rooms, Q&A, timelines, coordination with lawyers, tax advisors and auditors — all of this costs time and energy. Those who do not coordinate this professionally risk delays or even the failure of the deal. Here too the statistics show: with an advisor, completion rates increase significantly.

When Does an Advisor Really Pay Off?

The mathematics are surprisingly straightforward. Typical advisory fees in the mid-market are 3 to 6 percent of the purchase price. To recoup these costs, a price uplift of just 3 to 6 percent is sufficient. In practice, however, uplifts of 20 to 30 percent are observed — a multiple of the costs.

The economics are compelling in practice: when a professional advisor achieves a noticeably higher multiple through structured competition and better positioning, the additional proceeds generally exceed the advisory costs by a substantial margin. The right M&A advisor is therefore not a cost factor, but an investment in the maximum sale proceeds — and in the assurance that your life's work transitions under the best possible conditions.
