Conglomerate mergers and congeneric mergers are two types of business combinations with different characteristics from horizontal and vertical mergers. Horizontal mergers involve two competitors merging. Vertical mergers involve a buyer and a seller merging. 

Both of these types of mergers involve companies that are combining their related business operations. Congeneric mergers also involve companies in related lines of business, while conglomerate mergers do not.

Congeneric Mergers

Congeneric mergers involve companies in the same industry, but with different business lines. Both companies involved in the merger may have common technology, markets, or production processes. The acquired firm in a congeneric merger is either an extension of a product line or a market related to the acquiring firm.

A product extension merger happens when a new product line from an acquired firm is added to the existing product line of the acquiring firm. A market extension merger is when a new or closely-related market is added to the acquiring firm's existing markets through the acquired firm.

Conglomerate Mergers

Conglomerate mergers are mergers of two business firms engaged in unrelated business activities. The two firms are not two competitors merging as in horizontal mergers. They are also not a buyer and seller merging as in vertical mergers. They have no actual connection.

In theory, the firms in a conglomerate merger have no overlapping factors, but in practice, there is an aspect that they see as important that has drawn them together. They may see overlap in technologies, production, marketing, financial management, research, and development, or some other factor that makes them think they would be a good fit for each other.

Conglomerate mergers only make sense from a shareholder wealth perspective for two companies to merge if there is synergistic energy can best be explained by saying it is the 2 + 2 = 5 effect. In other words, if two companies merged.

Synergy is a concept you will often hear in business and, in particular, regarding mergers. In other words, the whole, the new company should be greater than the sum of the parts in order for the merger to make sense. If there isn't a synergistic effect between two merging companies, the combination of the companies may not be a shareholder-wealth-maximizing activity.

Why would two completely unrelated firms want to merge? Even though this reason is never stated by the merging firms, it is often about market power. Some firms think, "The bigger, the better." Economists who are anti-conglomerate think that acquisitions of smaller firms by big conglomerates cause less efficiency in the financial markets.

Along with market power, another reason one large firm may want to acquire another firm is to diversify its operations. If a large firm has just one line of business, it is very vulnerable to the ups and downs of the larger financial markets and the economy. If it introduces one or more new businesses in different areas under its umbrella, it diversifies its product line and becomes less vulnerable to the whims of the market.

Consideration of The Problem with Market Power

Firms that engage in horizontal mergers, as opposed to conglomerate firms, are more likely to merge to gain market power. Their mergers tend to consolidate industries. Take, for example, the banking industry.

Banks that have merged since 1980 have moved horizontally to acquire other banks. In many cases, larger banks have acquired many smaller banks. The banking industry, after the Deregulation and Monetary Control Act of 1980, has become very consolidated. Regional banks and large national banks have essentially taken control of the banking industry.

During the Great Recession of 2008, many saw the damage the big investment banks did to the economy. Additionally, many saw how banks shut down credit to small businesses in the U.S. during and after the recession. This would not have been such a huge problem if the banking industry had not been so consolidated. They had the market power, however, to do this.
