Business growth explained
Business growth means increasing scale — output, sales revenue, market share or capacity.
Read the full explanation
Organic growth (internal growth) expands the existing business: opening new outlets, raising output, winning new customers or launching new products, funded by retained profit or borrowing. External growth is integration (merger or takeover) with another firm. Forward vertical integration means merging with a customer further forward in the chain, such as a brewery buying pubs. Backward vertical integration means merging with a supplier further back, such as a bakery buying a flour mill. Horizontal integration means merging with a competitor at the same stage of the same industry, such as one supermarket chain taking over another. Conglomerate integration (diversification) means merging with a firm in an unrelated industry, such as a food manufacturer buying a clothing retailer.
Your focus
- Define organic growth and give one realistic example of a business expanding internally.
- Distinguish forward from backward vertical integration by identifying the stage of the firm being acquired.
- Classify a given merger as horizontal or conglomerate using the industry and stage of the two firms.
Business growth exam tips
Marking Points
- Organic growth is internal expansion of the existing business, for example opening additional outlets or increasing output, rather than merging with another firm.
- Forward vertical integration is integration with a customer at a later stage of the same production chain, for example a manufacturer acquiring a retail outlet.
- Backward vertical integration is integration with a supplier at an earlier stage of the same production chain, for example a retailer acquiring a manufacturer or raw-material supplier.
- Horizontal integration is integration with a competitor at the same stage of the same industry, for example one chain of coffee shops merging with a rival chain.
- Conglomerate integration is integration with a firm in a different, unrelated industry, for example a food producer acquiring a clothing retailer.
- The direction of vertical integration is judged from the perspective of the expanding firm: forward moves towards the final customer, backward moves towards the raw material.
Examiner Tips
- 💡Learn each type with one concrete example and check the direction from the expanding firm's own position in the chain.
- 💡In multiple-choice questions, eliminate options that describe the wrong stage or the wrong industry before choosing.
- 💡Practise classifying a merger you have read about in the news so the definitions become automatic.
Common Mistakes
- Confusing forward and backward vertical integration: the error is labelling integration with a supplier as forward. The correction is that backward integration moves towards the source of supply, while forward integration moves towards the customer.
- Treating horizontal integration as any merger between two firms: the error is ignoring the same-stage, same-industry condition. The correction is that horizontal integration involves a competitor at the same stage of the same industry.
- Calling conglomerate integration a vertical merger because the two firms trade with each other: the error is confusing a trading relationship with a production-chain relationship. The correction is that conglomerate integration joins firms in unrelated industries, so there is no supplier-customer link.
