KEY POINTS
Takeovers and mergers are methods of external growth.
A merger occurs when two businesses agree to join together to form one larger organisation.
A takeover occurs when one business gains control of another business.
Businesses may use takeovers and mergers to grow quickly, increase market share or access new markets.
Horizontal integration involves combining with a business at the same stage of production.
Vertical integration involves combining with a business at an earlier or later stage of production.
Takeovers and mergers can create economies of scale and synergy, but they can also lead to culture clashes and diseconomies of scale.
Strong exam answers judge whether external growth is suitable for the business context, not just whether it increases size.
KEY DEFINITION
Takeovers and Mergers
Takeovers and mergers are forms of external growth where businesses combine, either through one business gaining control of another or two businesses joining together.
Main Explanation
Takeovers and mergers are methods of external growth. External growth means that a business grows by combining with another business rather than expanding only through its own sales, output or new locations.
A merger occurs when two businesses agree to join together to form one larger organisation. This is often presented as a more equal combination, although in practice one business may still have more influence after the merger. A takeover occurs when one business gains control of another business, often by buying a majority of its shares or purchasing its assets.
Businesses may use takeovers and mergers because they allow rapid growth. Organic growth can be slower because the business has to build sales, capacity, reputation and customer loyalty over time. A takeover or merger may allow a business to gain customers, staff, technology, locations, suppliers or distribution channels much more quickly.
One possible benefit is increased market share. If a business takes over a competitor, it may gain access to that competitor’s customers and reduce the level of rivalry in the market. This could improve pricing power, increase sales and strengthen the business’s competitive position.
Takeovers and mergers may also create economies of scale. A larger business may be able to buy supplies in bigger quantities, spread marketing costs over more sales, use larger production facilities or reduce duplicated functions such as administration. This may reduce average costs and improve profitability.
Another possible benefit is synergy. Synergy means that the combined business may be worth more or perform better than the two separate businesses did before. For example, one business may have a strong brand while the other has better technology, skilled staff or production capacity. Combining these strengths may create a stronger overall organisation.
There are different types of integration. Horizontal integration occurs when businesses at the same stage of production and in the same or similar market combine. For example, one coffee shop chain buying another coffee shop chain would be horizontal integration. Vertical integration occurs when a business combines with another business at an earlier or later stage of production. Backward vertical integration involves moving closer to suppliers, while forward vertical integration involves moving closer to customers.
Conglomerate integration occurs when a business combines with another business in an unrelated market. This may help spread risk because the business is no longer dependent on one industry. However, conglomerate growth can be risky if managers lack experience in the new market.
Takeovers and mergers can also create serious problems. Integration may be difficult if the two businesses have different cultures, systems, management styles or working practices. Employees may resist change, morale may fall and talented staff may leave if they feel uncertain about their future.
Financial risk is another issue. A takeover can be expensive, especially if the acquiring business pays a high price or uses borrowed finance. If the expected benefits do not happen, the business may face lower profits, higher debt or weaker cash flow. Rapid growth can also create diseconomies of scale if the larger organisation becomes harder to manage.
There may also be concerns about competition. If a merger or takeover significantly reduces competition in a market, regulators may investigate whether customers could face higher prices, reduced choice or lower quality. This can delay the process or prevent the deal from going ahead.
Overall, takeovers and mergers can be powerful methods of growth, but they are not automatically successful. Strong exam answers should consider the strategic fit between the businesses, the cost of the deal, the likely synergies, the impact on employees and whether the combined business can be managed effectively.
✎ EXAMINER TIP
When answering questions on takeovers and mergers, avoid simply saying that the business will become larger. Explain how the growth affects costs, market share, competition, finance, employees and long-term strategic position.
KEY FORMULAS(s)
Profit and Profitability Formulas
These key formulas help you calculate different profit measures and profitability ratios used in business.
Gross Profit
Gross profit = Revenue − Cost of sales
The profit made after deducting direct costs.
!
Remember: profit shows how much money has been made, while profitability shows how efficiently revenue is being turned into profit.
DATA TABLE

Net profit is the final profit remaining after all costs and expenses have been deducted from revenue.
Benefits and Risks of External Growth

This chart compares the possible strategic benefits of takeovers and mergers with the risks that can occur during integration.
WORKED EXAMPLE
Worked Example: North Coast Coffee
How many coffees must be sold to break even?
Fixed Costs
£1,800
equity + long-term debt
Break-even output = Fixed costs ÷ Contribution per unit
Contribution per unit = Selling price − Variable cost
£3.50 − £1.10 = £2.40
1
Step 1: Calculate contribution
£3.50 − £1.10 = £2.40
Contribution per unit is the amount each coffee contributes towards fixed costs.
BREAK-EVEN OUTPUT:
750 coffees per month
EXAM TIP
Always explain what the number means for the business. Do not just calculate the break-even point.

Types of Integration in Takeovers and Mergers

This diagram shows how takeovers and mergers can involve horizontal, vertical or conglomerate integration depending on the relationship between the businesses.
APPLICATION
Fellside Foods
Fellside Foods produces chilled ready meals for supermarkets and online grocery retailers. The business has grown steadily, but competition has increased and supermarkets are putting pressure on suppliers to offer lower prices and more varied product ranges.
The directors are considering a takeover of Greenvale Deli, a smaller business that produces premium plant-based meals. This would be a form of external growth because Fellside Foods would grow by acquiring another business rather than expanding only through its own existing operations.
One possible benefit is that the takeover could give Fellside immediate access to a growing plant-based product range. Developing these products internally could take time, require research and involve trial-and-error. Taking over Greenvale Deli may allow Fellside to enter this market more quickly.
The takeover could also create economies of scale. Fellside may be able to use its larger production facilities, purchasing power and supermarket relationships to produce and distribute Greenvale’s products more efficiently. This could reduce average costs and help the combined business compete more effectively.
However, the takeover may create problems. Greenvale Deli has built its reputation on premium quality and small-batch production. If Fellside changes production methods too aggressively, it could damage the product’s appeal and lose loyal customers. There may also be culture clashes if Greenvale’s employees feel that the larger business does not understand its brand values.
The takeover would also require finance. If Fellside pays too much or uses borrowed funds, cash flow and profit may come under pressure. The strategy would only be suitable if the directors are confident that the benefits of faster growth, wider product ranges and economies of scale outweigh the risks of integration and financial strain.

Key Exam Tip
If you find it difficult to expand your answer and show the type of depth that an examiner is looking for in a top response, consider using the 'so what' approach.
Tesco carry out market research - so what? - this allows them to better understand customer needs - so what? as a result Tesco can provide goods more likely to sell - so what? - this will increase Tesco profit and ensure higher levels of customer satisfaction - so what? this means that customers are likely to become more loyal to Tesco.

MINI CASE STUDY
North Coast Coffee Ltd is a premium coffee business which sells freshly roasted coffee beans through its online store and a small chain of independent cafés. The business has experienced strong sales growth due to increasing demand for high-quality speciality coffee products.
The business generates annual revenue of £250,000. Its cost of sales, including coffee beans, packaging and direct production costs, totals £100,000. North Coast Coffee Ltd also faces operating expenses of £80,000, including marketing, employee wages, rent and administration costs. In addition, the business pays £20,000 in interest and taxation each year.
The owner, Mia Thompson, is reviewing the company’s profitability because rising wage costs and increased competition in the premium coffee market have started to place pressure on operating profit margins. She is considering increasing prices slightly in order to protect profitability while still maintaining customer demand.
