Control Premium
Investment Banking glossary · Investment Banking Valuation
Definition
Premium paid above the target's unaffected share price (the price prior to deal rumor) for control of the company: Control Premium = (Offer Price - Unaffected Price)/(Unaffected Price). Historically averages 25-40% for U.S. public-company deals; higher in competitive auctions and strategic transactions with material synergies, lower in negotiated sales, sponsor (LBO) deals, and distressed situations.
Control Premium in plain English
A control premium is the extra amount a buyer pays above a company's normal stock price to own enough of it to actually be in charge — to hire the CEO, set strategy, and decide what happens next. You measure it against the 'unaffected' price, meaning the price BEFORE any rumor of the deal leaked and pushed the stock up, so you capture the true premium and not hype. Historically buyers pay about 25-40% over that price, and it runs higher when several bidders are fighting in an auction or when a competitor expects big savings from combining, and lower in quiet negotiated or distressed sales. It's like the difference between buying a few shares of a pizza chain versus buying enough to fire the manager and change the recipe — full control is worth paying up for.
