What external growth is and its forms

External growth involves a business expanding by collaborating or combining with other firms, rather than relying solely on internal development. This approach enables companies to increase their size and market presence more rapidly.

Forms of external growth

• Mergers - This occurs when two firms agree to combine into a single entity, with shares from the new company distributed to the original shareholders. The primary goal is often to achieve synergy, where the combined firm becomes more profitable than the separate businesses were. This can result from higher revenues or reduced costs.
• Takeovers (acquisitions):
  • In this form, one firm purchases a controlling stake (over 50% of shares) in another, allowing it to make key decisions.
  • Takeovers can be agreed, where the target firm's owners consent to the sale for the business's benefit.
  • They can also be hostile, where shares are bought on the open market against the directors' wishes, often by offering shareholders a premium above the current share price.
• Ventures:
  • These are new projects or small businesses created by one or more existing firms to generate profits, typically targeting unmet market needs.
  • When multiple firms collaborate, it becomes a joint venture, where resources are shared without changing ownership.
  • Joint ventures spread risks, provide access to new markets, and allow firms to start operations without bearing all the costs alone.
  • Upon ending, profits are divided, and the original firms remain independent.

Types of external growth

External growth can be classified based on the relationship between the combining firms and their positions in the industry or market. These types help businesses strategically expand while addressing specific goals, such as reducing rivalry or securing supply chains.

Horizontal integration

This happens when firms at the same production stage in the same industry combine, often through mergers or takeovers. It reduces the number of competitors, potentially increasing market share. For example, two car makers joining forces to dominate their national market.

Vertical integration

This involves combining with a firm in the same industry but at a different production stage.

Types of vertical integration:

• Forward vertical integration - A firm merges with or acquires one further along the supply chain, such as a drinks manufacturer taking over a chain of shops. This provides direct control over sales outlets, enabling the exclusion of rivals' products and better access to customers.
• Backward vertical integration - A firm combines with one earlier in the chain, like a furniture retailer acquiring a timber supplier. This secures reliable raw materials and prevents supply disruptions.

Conglomerate mergers

These occur between firms that are not direct competitors, suppliers, or customers.

Types of conglomerate mergers:

• Pure conglomerate mergers - Involves completely unrelated businesses.
• Product extension mergers - Combines firms with related but not identical products, such as a maker of garden tools merging with a plant nursery.
• Geographic market mergers - Joins firms in the same industry but operating in different regions, expanding reach without overlapping markets.

Benefits of and reasons for external growth

External growth offers several advantages over internal expansion, allowing firms to scale up operations swiftly and efficiently. It also serves specific strategic purposes that drive businesses to pursue these methods.

Benefits of external growth

• Provides a faster path to expansion compared to building from within.
• Quickly boosts resources, including production capacity, employees, equipment, knowledge, and intellectual property.
• Enhances market share, leading to higher sales volumes and stronger competitive positioning.

Reasons for external growth

• Diversification - Allows entry into new product areas or customer segments by partnering with established players.
• Reducing competition - Eliminates rivals through mergers or takeovers in the same sector.
• International expansion - Facilitates entry into foreign markets by combining with local firms that have existing networks and knowledge.
• Economies of scale and scope - Lowers average costs by sharing operations and enables production of a wider range of goods more efficiently.
• Production flexibility - Acquiring facilities in various locations allows switching output to areas with lower costs, such as cheaper labour.
• Technology acquisition - Gains access to advanced tools, processes, or skills without developing them internally.

Risks of external growth

While external growth can accelerate expansion, it comes with potential downsides that firms must manage carefully. These risks can affect operations, finances, and long-term success.
