External Growth (Cambridge International A-Level Economics)

External growth

• External growth occurs when a firm expands by merging with or acquiring another firm

  • This is often faster than internal growth

Types of external growth

• External (inorganic) growth usually takes place in one of three ways

  • Horizontal, vertical or conglomerate integration

A diagram that illustrates how a firm can grow through forward or backward vertical integration

1. Horizontal integration

• Horizontal Integration involves a merger or takeover with a firm in the same market at the same stage of production

  • E.g., a clothing retailer takes over another clothing retailer

• Benefits may include:

  • increased market share
  • reduced competition
  • greater economies of scale

2. Forward vertical integration

• involves a merger or takeover with a firm further forward in the supply chain

  • E.g., a dairy farmer merges with an ice-cream manufacturer

• Benefits of forward vertical integration

  • Greater control over distribution and sales

    • The firm can control how products are marketed, priced and sold to consumers

  • Higher profit margins

    • By removing intermediaries such as wholesalers or retailers, the firm keeps a larger share of the final sale price

  • Better market information

    • Direct contact with consumers provides insights into customer preferences and demand trends

Case Study Apple's growth

Apple produces products such as the iPhone, iPad and Mac computers. In many technology markets, manufacturers rely on independent retailers or network providers to sell their products. This limits the firm’s control over pricing, marketing and customer experience.

Apple used forward vertical integration to grow and increase profit margins

Growth strategy

Apple pursued forward vertical integration by expanding its own network of Apple Stores and online retail platforms. By selling directly to consumers, Apple moved forward in the supply chain, taking control of the distribution and retail stages. This allowed the firm to manage how its products are displayed, marketed and supported.

Outcome

This strategy has helped Apple maintain strong control over branding, pricing and customer experience. Apple also benefits from higher profit margins, as it no longer shares revenue with independent retailers. Direct contact with consumers also provides valuable market information about customer preferences.

3. Backward vertical integration

• Involves a merger or takeover with a firm further backward in the supply chain

  • E.g., an ice-cream retailer takes over an ice-cream manufacturer

• Benefits of backward vertical integration

  • Greater security of supply

    • The firm reduces the risk of supply disruptions from external suppliers

  • Lower input costs

    • Producing inputs internally can reduce purchasing costs and improve cost control

  • Improved production coordination

    • Better control over inputs can improve efficiency, quality and production planning

4. Conglomerate integration

• Involves a merger or takeover with a firm in an unrelated market

  • E.g., a food manufacturer buying a football club

• Benefits of conglomerate integration

  • Risk diversification

    • Operating in multiple unrelated industries reduces dependence on a single market

  • Access to new growth opportunities

    • Firms can enter profitable industries and expand their sources of revenue

Exam Hint Look carefully at the two types of businesses you have been presented with and make a judgement about the most likely reason they have chosen to grow

Reasons for integration

• Firms pursue mergers and takeovers for several reasons

Consequences of integration

• Integration can have several outcomes, either positive or negative, or a combination of the two
