Inorganic growth: mergers, takeovers and integration
Edexcel IAL Business · WBS13 Business decisions and strategy
Inorganic growth is fast but risky. This lesson distinguishes mergers from takeovers, sets out the types of integration and conglomerates, and weighs the financial risks and rewards.
Mergers and takeovers
- A merger is when two (or more) businesses agree to join to form one new business, usually with shareholders of both receiving shares in the combined firm.
- A takeover (acquisition) is when one business buys a controlling interest (more than 50% of the voting shares) in another. It may be friendly (the target's board recommends the offer) or hostile (the board opposes it and the bidder appeals directly to shareholders).
Reasons: rapid growth, economies of scale, a bigger market share and market power, removing a rival, entering new markets, gaining new products, brands, technology or skills, securing supplies or distribution, and spreading risk.
Types of integration
| Type | Meaning | Example |
|---|---|---|
| Horizontal | Firms at the same stage of production in the same industry | Two supermarket chains join |
| Vertical backward | A firm joins with a supplier (earlier stage) | A chocolate maker buys a cocoa processor |
| Vertical forward | A firm joins with a business nearer the customer (later stage) | A brewer buys a chain of bars |
| Conglomerate | Firms in unrelated industries | A food company buys an insurance firm |
Financial risks and rewards
Rewards: higher revenue and profit from a larger, stronger business; cost savings (synergies) from cutting duplicated costs such as two head offices; economies of scale; market power; a higher share price if investors approve.
Risks:
- Overpaying: bidders often pay a premium above the market value of the target's shares; if the expected synergies do not appear, value is destroyed.
- Funding: borrowing to pay for a takeover raises gearing and interest costs; issuing new shares dilutes existing owners' control.
- Integration costs: redundancy payments, new IT systems and rebranding.
- Culture clash and loss of key staff, which can reduce productivity.
- Regulation: competition authorities may block or set conditions on horizontal mergers that reduce competition.
Advantages and disadvantages by type
| Type | Advantages | Disadvantages |
|---|---|---|
| Horizontal | Economies of scale; market share and power; removes a rival | May be blocked by regulators; culture clash; duplication to cut |
| Vertical backward | Secures supply, quality and cost; takes the supplier's margin | Needs new expertise; less flexibility to switch to better suppliers |
| Vertical forward | Controls distribution and the customer experience; gains retail margin | Retailing needs different skills; may upset other retailers |
| Conglomerate | Spreads risk across unrelated markets | Few synergies; managers lack knowledge of the new industry; diseconomies of scale |
Worked example
A coffee chain is offered the chance to buy the roasting company that supplies it, for $8m funded by a bank loan. Analyse the risks and rewards.
- Type: backward vertical integration.
- Rewards: secures bean supply and quality; the roaster's profit margin now stays in the group; the chain may be able to sell roasted beans to others.
- Risks: the loan raises gearing and interest costs; roasting needs different skills; if bean prices fall, the chain cannot easily switch to a cheaper supplier.
- Judgement: worthwhile if supply security and quality are central to the chain's brand and it can service the loan from cash flow.
Answer: Backward vertical integration: secures supply and margin, but raises gearing and reduces flexibility.
Check yourself
- What defines a takeover?
- One business buys a controlling interest in another
- Two businesses agree to form a new combined business on equal terms
- A business opens new branches
- Two businesses set up a jointly owned new firm
Show answer
One business buys a controlling interest in another. Control passes to the buyer, usually more than 50% of voting shares.
- Two airlines that fly similar routes combine. This is
- backward vertical integration
- forward vertical integration
- horizontal integration
- a conglomerate merger
Show answer
horizontal integration. Same industry, same stage of production.
- A clothing manufacturer buys a chain of fashion shops. This is
- forward vertical integration
- backward vertical integration
- horizontal integration
- organic growth
Show answer
forward vertical integration. The shops are nearer the final customer.
- Which is the main reason for a conglomerate takeover?
- To gain the largest technical economies of scale
- To secure supplies of raw materials
- To remove a direct competitor
- To spread risk across unrelated markets
Show answer
To spread risk across unrelated markets. Unrelated markets diversify risk.
- A takeover bid that the target company's board of directors rejects is called
- a friendly takeover
- a hostile takeover
- a merger
- a demerger
Show answer
a hostile takeover. The bidder then appeals directly to shareholders.
- Which is a financial risk of funding a takeover with a large loan?
- Existing shareholders' control is diluted
- The business loses its brand
- Labour productivity rises
- Gearing rises and interest payments may strain cash flow
Show answer
Gearing rises and interest payments may strain cash flow. Debt brings fixed interest costs and higher gearing.
- A bidder offers $6.30 per share for a company whose shares were trading at $4.50 before the bid. Calculate the premium as a percentage of the pre-bid share price.
Show answer
40 %. (6.30 - 4.50) / 4.50 x 100 = 40%. Paying a large premium raises the risk of overpaying.
- Explain why a clash of cultures could reduce the benefits of a merger.
Show answer
If the two businesses have different values and ways of working, staff may resist change, become demotivated or leave, so productivity falls and the expected cost savings are not achieved.. Name the cultural difference, its effect on staff, and the effect on the merger's benefits.
