It's no secret that plenty of mergers don't work. Research shows that 70-80% of mergers fail.Those who advocate mergers will argue that the merger will cut costs or boost revenues by more than enough to justify the price premium. It can sound so simple: just combine computer systems, merge a few departments, use sheer size to force down the price of supplies and the merged giant should be more profitable than its parts. In theory, 1+1 = 3 sounds great, but in practice, things can go awry.
Historical trends show that roughly two thirds of big mergers will disappoint on their own terms, which means they will lose value on the stock market. The motivations that drive mergers can be flawed and efficiencies from economies of scale may prove elusive. In many cases, the problems associated with trying to make merged companies work are all too concrete.
A merger may often have more to do with glory-seeking than business strategy. The executive ego, which is boosted by buying the competition, is a major force in M&A, especially when combined with the influences from the bankers, lawyers and other assorted advisers who can earn big fees from clients engaged in mergers. Most CEOs get to where they are because they want to be the biggest and the best, and many top executives get a big bonus for merger deals, no matter what happens to the share price later.
On the other side of the coin, mergers can be driven by generalized fear. Globalization, the arrival of new technological developments or a fast-changing economic landscape that makes the outlook uncertain are all factors that can create a strong incentive for defensive mergers. Sometimes the management team feels they have no choice and must acquire a rival before being acquired. The idea is that only big players will survive a more competitive world.
