The phrase mergers and acquisitions (abbreviated M&A) refers to the aspect of corporate strategy, corporate finance and management dealing with the buying, selling and combining of different companies that can aid, finance, or help a growing company in a given industry grow rapidly without having to create another business entity.

Overview

A merger is a tool used by companies for the purpose of expanding their operations often aiming at an increase of their long term profitability. There are 15 different types of actions that a company can take when deciding to move forward using M&A. Usually mergers occur in a consensual (occurring by mutual consent) setting where executives from the target company help those from the purchaser in a due diligence process to ensure that the deal is beneficial to both parties. Acquisitions can also happen through a hostile takeover by purchasing the majority of outstanding shares of a company in the open market against the wishes of the target's board. In the United States, business laws vary from state to state whereby some companies have limited protection against hostile takeovers. One form of protection against a hostile takeover is the shareholder rights plan, otherwise known as the "poison pill".

Historically, mergers have often failed (Straub, 2007) to add significantly to the value of the acquiring firm's shares (King, et al., 2004). Corporate mergers may be aimed at reducing market competition, cutting costs (for example, laying off employees, operating at a more technologically efficient scale, etc.), reducing taxes, removing management, "empire building" by the acquiring managers, or other purposes which may or may not be consistent with public policy or public welfare. Thus they can be heavily regulated, for example, in the U.S. requiring approval by both the Federal Trade Commission and the Department of Justice.

The U.S. began their regulation on mergers in 1890 with the implementation of the Sherman Act. It was meant to prevent any attempt to monopolize or to conspire to restrict trade. However, based on the loose interpretation of the standard "Rule of Reason", it was up to the judges in the U.S. Supreme Court whether to rule leniently (as with U.S. Steel in 1920) or strictly (as with Alcoa in 1945).

Acquisition

main: Takeover

An acquisition, also known as a takeover, is the buying of one company (the ‘target') by another. An acquisition may be friendly or hostile. In the former case, the companies cooperate in negotiations; in the latter case, the takeover target is unwilling to be bought or the target's board has no prior knowledge of the offer. Acquisition usually refers to a purchase of a smaller firm by a larger one. Sometimes, however, a smaller firm will acquire management control of a larger or longer established company and keep its name for the combined entity. This is known as a reverse takeover.
