Control Premium

A control premium is the markup a buyer pays to gain control over a company. Whoever holds the majority can determine strategy, management, and the use of profits, and is therefore willing to pay more. The premium is above the price that individual shares without control would be worth.

Economically it rests on concrete rights: appointing management, setting strategy, deciding on distributions and investment, access to cash flow and the ability to realise synergies with the buyer's own business. It is usually measured as a premium to the unaffected share price before the offer became known. An observed takeover premium may include synergies and competition among bidders as well as the value of control. It is therefore not a standard premium that can automatically be applied to every controlling stake. The distinction from the minority discount matters, because both describe the same fact from opposite directions and use different starting values. A control value of 120 against a minority value of 100 implies a 20 percent premium but a discount of about 16.7 percent.

For valuation this raises the question of which level is already contained in the starting figure, since share prices value minority stakes while precedent transactions already reflect controlling stakes and therefore justify no additional premium. It matters in practice that observed premiums vary widely and depend on competition, occasion and bargaining position: a bidder without rivals pays less than one in a competitive process, and a buyer with large synergies can economically justify a higher price. For unlisted companies there is no observable starting price at all, so the question is answered there not as a premium but through the choice of comparable data.
