Multiple Arbitrage

Multiple arbitrage refers to the increase in value that arises when a company is sold at a higher multiple than it was bought for. Even without operational improvement, value increases purely through the higher valuation factor. Private equity investors often achieve this by combining small companies and selling them as a larger unit at a higher price. The effect rests on larger companies regularly trading at higher multiples, because they appear more stable, appeal to a wider buyer universe, have more professional structures and are eligible for institutional investors at all.

A numerical example shows the leverage: if a platform with ten million euros of EBITDA is acquired at eight times and add-ons with a combined five million of EBITDA at five times, the weighted entry multiple is around seven. Selling the group at ten times produces a substantial value contribution from the valuation gap alone. Beyond size, other factors affect the exit multiple, in particular a higher share of recurring revenue, lower customer concentration, a capable second management tier and documented processes. The distinction from pure market movement matters: a higher multiple resulting merely from generally risen valuation levels or favourable credit markets is not the result of the investor's own work and cuts the other way when conditions deteriorate. Investors therefore show this contribution separately in their value bridge.

It should be borne in mind that the effect does not arise automatically: a buyer pays a higher factor only if the group genuinely functions as one unit, meaning shared systems, standardised processes, a capable management structure and consolidated accounts. Without those conditions the group is valued at exit as the sum of separate businesses and the hoped-for effect fails to materialise. That is precisely what determines whether a buy-and-build strategy justifies the effort.
