Horizontal Integration
- Horizontal integration is the process of acquiring or merging with competitors, leading to industry consolidation.
- Horizontal integration is a strategy where a company acquires, mergers, or takes over another company in the same industry value chain.
It is a type of integration strategies pursued by a company in order to strengthen its position in the industry. A corporate that implements this type of strategy usually mergers or acquires another company that is in the same production stage. For example, Disney merging with Pixar (movie production), Exxon with Mobile (oil production, refining, and distribution) or the infamous Daimler Benz and Chrysler merger (car developing, manufacturing and retailing).
The purpose of horizontal integration (HI) is to grow the company in size, increase product differentiation, achieve economies of scale, reduce competition, or access new markets. When many firms pursue this strategy in the same industry, it leads to industry consolidation (oligopoly or even monopoly).
HI can occur in a form of mergers, acquisitions, or hostile takeovers. The merger is the joining of two similar sizes, independent companies to make one joint entity. The acquisition is the purchase of another company. A hostile takeover is the acquisition of the company, which does not want to be acquired.
HI may be an effective strategy when:
- Organization competes in a growing industry.
- Competitors lack some capabilities, competencies, skills, or resources that the company already possesses.
- HI would lead to a monopoly that is allowed by a government.
- Economies of scale would have a significant effect.
- The organization has sufficient resources to manage M&A.
The following diagram illustrates HI in manufacturing industry:
Difference between horizontal and vertical integrations
HI is different from vertical integration, where a firm usually expands into another production stage rather than merging or acquiring the company in the same production stage. For example, a company is vertically integrating if it expands from the manufacturing industry to the retailing industry, while HI would mean buying other firms in the same manufacturing industry.
