Most businesses aim to grow over time. Growth can increase revenue, profit, market share, and the value of the business. This lesson explores the different ways businesses can grow and the advantages and disadvantages of each approach.
| Reason | Explanation |
|---|---|
| Increased revenue and profit | Larger businesses can generate more sales and profit |
| Economies of scale | Larger businesses can reduce costs per unit through bulk buying, specialisation, and spreading fixed costs |
| Increased market share | A larger share of the market gives more influence and pricing power |
| Diversification | Growth allows businesses to enter new markets and reduce dependence on one product or market |
| Increased brand recognition | Larger businesses are more widely known and trusted |
| Greater security | Larger businesses are often more resilient to market changes |
Organic growth is when a business expands using its own resources, without merging with or acquiring other businesses.
| Method | Description | Example |
|---|---|---|
| Increasing sales | Selling more of existing products to existing or new customers | Greggs opening more stores across the UK |
| Launching new products | Developing and introducing new products to the market | Apple launching the Apple Watch |
| Opening new locations | Expanding into new geographic areas | Nando's opening restaurants in new countries |
| E-commerce expansion | Selling online to reach a wider customer base | Next launching a successful online store |
| Increasing market share | Winning customers from competitors | Aldi gaining market share from Tesco |
| Franchising | Allowing franchisees to open new outlets under the brand | McDonald's expanding through franchisees |
External growth involves expanding by joining with or taking over other businesses. It is typically faster than organic growth but carries more risk.

| Type | Description | Example |
|---|---|---|
| Merger | Two businesses agree to combine and form a new, larger business | Dixons and Carphone Warehouse merged to form Dixons Carphone |
| Takeover (acquisition) | One business buys another business (the target company) | Facebook acquired Instagram for $1 billion in 2012 |
| Friendly takeover | The target company's board of directors agrees to the acquisition | Disney acquiring Pixar in 2006 |
| Hostile takeover | The acquiring company buys shares against the wishes of the target's management | Kraft's hostile takeover of Cadbury in 2010 |
| Type | Description | Example |
|---|---|---|
| Horizontal integration | Merging with or acquiring a business at the same stage of production in the same industry | Tesco acquiring Booker (both retailers/wholesalers) |
| Vertical integration (forward) | Acquiring a business further along the supply chain (closer to the customer) | A brewery buying a chain of pubs |
| Vertical integration (backward) | Acquiring a business earlier in the supply chain (closer to raw materials) | A car manufacturer buying a tyre company |
| Conglomerate integration | Merging with or acquiring a business in a completely different industry | Amazon acquiring Whole Foods (tech + groceries) |
Exam Tip: When evaluating growth strategies, consider the speed, risk, cost, and control implications. Organic growth is slower but safer; external growth is faster but riskier. The best strategy depends on the business's objectives, resources, and market conditions.
AQA 8132 requires students to understand the link between growth and average unit costs.
Economies of scale are cost advantages that businesses gain as they grow larger — unit costs fall because fixed costs are spread across more output and buying power increases.
| Type | How it reduces unit cost |
|---|---|
| Purchasing economies | Bulk buying secures supplier discounts (Tesco vs a corner shop) |
| Technical economies | Large-scale machinery and automation cut cost per unit produced |
| Managerial economies | Specialist managers (finance, HR, marketing) can be employed full-time |
| Financial economies | Larger firms borrow more cheaply and access wider capital markets |
| Marketing economies | Marketing costs spread over many more units of output |
Diseconomies of scale are the opposite — as businesses get too big, unit costs start rising again due to:
Understanding this U-shaped cost curve is central to evaluating whether further growth is actually worthwhile.
In 2020, UK-based Just Eat merged with Dutch rival Takeaway.com in a £6.2 billion all-share deal to form Just Eat Takeaway.com (JET). The aim was to create a European food-delivery giant that could take on rivals Deliveroo, Uber Eats, and DoorDash. The merger was approved by the UK Competition and Markets Authority (CMA) after investigation. Shortly afterwards, JET also acquired US rival Grubhub for $7.3 billion — making it one of the largest online food-delivery businesses in the world by transaction value.
This is a textbook example of external growth through horizontal integration: all three businesses operated at the same stage of the supply chain (connecting customers to restaurants), in the same industry. The theoretical benefits were clear:
What went wrong. Despite the scale, the merger has been widely viewed as a failure. JET's share price fell from over £100 in 2021 to below £15 in 2023 — a loss of nearly £20 billion in market value. Reasons included:
In 2023, JET announced it was considering a sale of Grubhub, cutting UK jobs, and exiting some markets. The saga illustrates the classic disadvantages of external growth: cultural integration is hard, synergies often fall short, and fast expansion can expose the business to macroeconomic shocks.
Misconception: "Mergers and takeovers always benefit the businesses involved because they create a bigger business."
Reality: Research consistently shows that a large proportion of mergers fail to create shareholder value — some studies put the failure rate at 50-70%. Famous UK cases include the disastrous Royal Bank of Scotland acquisition of ABN Amro in 2007, which contributed to RBS's near-collapse and a £45 billion government bailout. The Just Eat Takeaway.com story shows the same pattern. Growth for its own sake is rarely successful. The best external growth happens when there is a clear strategic fit, careful cultural integration, and disciplined valuation.
Question (9 marks): Analyse the benefits and drawbacks of external growth compared with organic growth for a UK clothing retailer.
Grade 3-4 response:
External growth is when a business buys another business. Organic growth is when a business grows on its own. External growth is faster because the new business is bigger straight away. But it is expensive. Organic growth is cheaper but slower. It depends which one the clothing retailer wants.
Examiner view: Basic definitions, no specific examples, no chains of reasoning, no evaluation.
Grade 5-6 response:
For a UK clothing retailer, external growth (e.g. buying a rival) offers fast access to new shops, customers, and brands, as shown by Next buying JoJo Maman Bébé and FatFace in 2023 to expand its range. This removes a competitor and spreads Next's existing infrastructure across more sales. However, it is expensive — Next paid over £100 million — and there are risks of culture clash and integration problems. Organic growth is slower (e.g. opening 10 new stores a year) but lower-risk and self-funded from retained profit. Overall, external growth is faster but riskier; organic growth is steadier and better for smaller retailers.
Examiner view: Good UK example (Next), reasonable two-sided argument with mini-judgement.
Grade 7-9 response:
For a UK clothing retailer, the choice between external and organic growth depends on its objectives, market position, and risk tolerance — each approach has distinct strategic implications.
External growth is fast and can deliver immediate scale. Next plc has demonstrated this model successfully by acquiring stakes in or ownership of brands like JoJo Maman Bébé, FatFace, and Cath Kidston. These acquisitions gave Next instant access to new customer segments (maternity, rural lifestyle, vintage-florals) that would have taken many years to build organically. Financial economies of scale are significant: Next can plug acquired brands into its existing warehousing, returns processing, and website platforms — reducing unit costs immediately.
However, external growth carries substantial risks. Culture clashes can destroy value (as seen in the Just Eat Takeaway.com merger, which lost £20 billion in market cap). Overpayment is common — Boohoo's £55m acquisition of Debenhams brand in 2021 delivered much less than hoped. Integration is complex: combining IT systems, supply chains, and management teams takes years. The Competition and Markets Authority may also block deals if they reduce competition, as happened with the proposed Sainsbury's-Asda merger in 2019.
Organic growth — opening new stores, launching new ranges, growing e-commerce — is slower but gives greater control. Primark has grown almost entirely organically, opening stores carefully in new markets and refining its low-cost model. Organic growth preserves culture, reduces financial risk, and can be funded from retained profit without the need for large external financing. The drawback is speed: in a fast-changing fashion market, competitors may leapfrog an organic-only firm with bold acquisitions.
Overall, the best approach depends on the retailer's stage and market context. A mature retailer with strong infrastructure (like Next) can extract real value from selective acquisitions. A growing brand with a distinctive identity (like Primark) should generally prioritise organic growth to protect its culture. In practice, most successful UK retailers use both strategies together — organic growth for core brands, external growth for diversification. The key is to use external growth strategically, not opportunistically, and to be disciplined about valuation and integration planning.
Examiner view: Excellent use of multiple UK examples (Next, Primark, Boohoo, JET, Sainsbury's-Asda), developed chains of reasoning linking strategy to outcomes, sophisticated evaluation, and a justified, nuanced judgement recognising that the choice is not binary.
