Explain mergers, takeovers and integration
Classify external growth and distinguish horizontal from vertical integration using the firms' positions in a market or supply chain.
Exam scope and assessment notes
Cambridge IGCSE Business Studies 0450, 2026 syllabus, Version 2. Use the 2026 A*–G route; this qualification changes to 0264 for first assessment in 2027. Candidates are not assessed on constructing income statements or statements of financial position, nor on price-elasticity or exchange-rate calculations. Simple cash-flow forecast construction is assessed. Written practice is self-checked, not an official Cambridge grade; timed-paper evidence and human subject-teacher review remain outstanding.
Before you begin
- No previous business study is assumed. Read each scenario for the decision-maker, objective, available evidence and constraints.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
Two rival bakeries at the same production stage combine. What type of integration is this?
What you will learn
- Define merger and takeover
- Distinguish horizontal and vertical integration
- Use integration to explain potential benefits and risks
External growth combines businesses
External growth occurs when a business expands by combining with or acquiring another business. A merger combines businesses by agreement; a takeover occurs when one business gains control of another.
Horizontal integration combines businesses at the same stage of production in the same industry, often competitors. Vertical integration combines businesses at different stages of a supply chain.
Specify the direction of vertical integration
Backward vertical integration moves toward a supplier; forward integration moves toward distribution or the customer. Use the firms' actual roles to classify the change.
A combination may increase market reach, control over supplies or distribution, but can create integration difficulties, costs or reduced competition. The result depends on context and management.
Pause and explain
A furniture maker acquires a timber supplier. Which direction is this?
Worked example
A shoe retailer acquires a shoe manufacturer. Classify the growth and state the vertical direction.
Show the worked solution
- The businesses are at different stages of the supply chain.
- The retailer moves toward production rather than toward consumers.
- Classify it as backward integration.
Answer External growth through a takeover and backward vertical integration, because the retailer acquires a supplier/manufacturer upstream.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
A supermarket acquires a competing supermarket in the same city. Classify the growth and explain one possible objective.
Give me a hint
Compare the firms' stage and industry.
Compare my reasoning
- Both are retailers in the same industry.
- The acquisition is external growth.
- A possible objective is wider market share, subject to competition and integration.
External growth by takeover and horizontal integration. The supermarket may seek a larger customer base or market share, but must consider acquisition cost and competition rules.
Look for these in your work
- External growth named
- Horizontal relation shown
- Objective bounded
A clothing manufacturer buys an online distribution platform. Classify the integration direction and one operational challenge.
Give me a hint
The platform is closer to the final customer than manufacturing.
Compare my reasoning
- It moves downstream toward distribution.
- This is forward vertical integration.
- Systems, service standards or customer data may be difficult to integrate.
Forward vertical integration. The manufacturer may gain control over distribution, but it must integrate the platform's systems, staff and customer-service processes.
Look for these in your work
- Stage relationship identified
- Direction correct
- Challenge specific
A company says a merger will reduce costs because it combines two firms. Evaluate the claim with one possible saving and one risk.
Give me a hint
Use a mechanism for the saving and a condition or cost that could offset it.
Compare my reasoning
- Combining purchasing or duplicated administration could reduce some costs.
- Integration, restructuring or coordination may add costs.
- Savings depend on the firms and how the combination is managed.
The merger may remove duplicated administration or improve purchasing terms, but integration and restructuring can be expensive or disrupt operations. Cost savings are possible, not guaranteed.
Look for these in your work
- Saving mechanism explained
- Risk considered
- Conclusion conditional
Common mistakes
- Calling any acquisition horizontal
- Confusing forward and backward integration
- Assuming a merger automatically lowers costs
What can you explain now?
Two rival bakeries at the same production stage combine. What type of integration is this?
Compare with the explanation
Horizontal integration
They operate at the same stage in the same industry.
