What is Horizontal Integration?

Horizontal integration is a competitive strategy where business entities operating at the value chain level and within the same industry merge to increase the production of goods and services. The overall gain from a horizontal integration is an increase in the market power and minimal loss for being non-integrated.

Horizontal Integration

Horizontal integration can be contrasted with vertical integration, where a company takes control of its supply chain and value by owning its suppliers, distributors, or retail locations.


  • Horizontal integration happens when one firm acquires another firm operating in the same industry or producing the same line of products.
  • Companies that engage in horizontal integration may realize economies of scale, reduced production costs, synergy in marketing, increased revenue, among others.
  • As with any other business strategy, horizontal integration does not always lead to increased value and profitability as expected. Instead, it can be the precursor  to dismal performance, devaluation, inefficiency, stunted economic growth, and reduced competitiveness.

Understanding Horizontal Integration

Horizontal integration is a competitive strategy that can result in economies of scale, competitive edge, increased market share, and business expansion. Businesses in strategic alliances target outcomes that provide more resources, market, competence, and efficiency. The two amalgamated entities should be better positioned to realize more revenue than they would have when operating independently.

Horizontal integration may also involve the optimization of activities or the consolidation of strategic business activities within the firm’s scope of processes and activities. It may arise from expansion to new market segments, economies of scale, economies of scope and experience, and the price difference in the factors of production.

However, these business combinations may create a monopoly power in an industry, which may be a disadvantage to the consumer. The reduced competition may induce collusive behavior, leading to increased prices for products.

Aspects of Horizontal Integration

There are several aspects that characterize a horizontal integration versus other business combinations. They include:

  • The direction of horizontal integration
  • Profitability of integration
  • Target of integration
  • Forms and intensity of integration

Horizontal integration can be distinguished from conglomerate integration by taking into account the direction. It is usually a preserve for companies with financial surpluses. Horizontal mergers of related companies occur within the same industry or line of products so that the entities involved can exploit their competencies.

Companies merge and expand their activities as a unit in sectors related to associated products or services to utilize their skills and resources. Businesses that aim to increase their profitability can adopt horizontal integration within the same product lines.

On the other end of the spectrum, conglomerate diversification is for companies that strive for growth. Notwithstanding this rule, some companies may use only the selected competencies of horizontal integration.

Horizontal Integration vs. Vertical Integration

Horizontal integration and vertical integration are strategic alliances by companies in the same sector. The horizontal integration of companies within the same industry attracts businesses that target to reach a broader market or offer more products/services. It can lead to product diversification, increased company size, narrow competition, and economies of scale.

A successful horizontal integration equips companies with the ability to cut down on costs by using the same research and development, technologies, marketing and advertising, production, and distribution. The need to acquire a new customer segment can also be a reason for horizontal integration.

In a vertical integration, a business entity acquires another business operating in the production process of the same industry. They are combinations with companies that are upstream or downstream of the same product supply chain.

Companies may choose to undergo vertical integration to increase profitability, reduce production costs, and strengthen their supply chain. Integrating vertically requires one company that is higher or below in the supply chain process. They can draw several benefits from vertical integration, including increased profits from the new business operations, efficiency in the production process, and enhanced distribution and delivery.

Horizontal Integration vs. Vertical Integration

Benefits of Horizontal Integration

1. Larger market share

Successful mergers create a large market share for the integrated company or business units. Horizontally integrated firms improve market share by the expansion of business activities, cost synergies in marketing, combined product base, and shared technology, among others.

2. Large customer base

When two companies come together, they also bring different consumer bases. As a result, the new firm has access to a large customer segment.

3. Higher revenue

By increasing its market share and consumer base, the new company has the ability to increase its revenue two-fold or more.

Drawbacks of Horizontal Integration

Despite the increased potential profitability of horizontal integration from the increased value and synergies, the strategy has some potential drawbacks:

1. Threatens competition

Mergers and acquisitions of large corporations usually lead to monopolies to the detriment of consumers. Market dominance may fuel unethical practices, such as indefinite hiking of market prices or narrowing of products and services. For this reason, monopolies are subject to antitrust laws, not to mention the scrutiny of regulatory bodies.

2. Reduces flexibility

Horizontal integration may impede the flexibility of the acquired firm since it must conform to the operations of the bigger company.
