Types of integration

  • External growth usually takes place when firms join in one of three broad ways

1. Vertical integration

  • This is a merger or takeover of another firm in the supply chain or different stage of the production process

    • E.g. An ice cream manufacturer merges with a dairy farm or an ice cream cafe chain

Examples of vertical integration

  • Forward vertical integration involves a merger or takeover with a firm further forward in the supply chain

    • E.g. A dairy farmer merges with an ice cream manufacturer

  • Backward vertical integration involves a merger/takeover with a firm further backwards in the supply chain

    • E.g. An ice cream retailer takes over an ice cream manufacturer

Evaluating vertical integration

Advantages

Disadvantages

  • Reduces the cost of production as middleman profits are eliminated

  • Lower costs make the firm more competitive

  • Greater control over the supply chain reduces risk as access to raw materials is more certain

  • The quality of raw materials can be controlled

  • Forward integration adds additional profit as the profits from the next stage of production are assimilated

  • Forward integration can increase brand visibility

  • Diseconomies of scale occur as costs increase, e.g. unnecessary duplication of management roles

  • There can be a culture clash between the two firms that have merged

  • Possibly little expertise in running the new firm results in inefficiencies

  • The price paid for the new firm may take a long time to recoup

2. Horizontal integration

  • This is a merger or takeover of a firm at the same stage of the production process

    • E.g. An ice cream manufacturer buys another ice cream manufacturer

Evaluating horizontal integration

Advantages

Disadvantages

  • A rapid increase of market share

  • Reductions in the cost per unit due to economies of scale

  • Reduces competition

  • Existing knowledge of the industry means the merger is more likely to be successful

  • The firm may gain new knowledge or expertise

  • Diseconomies of scale may occur as costs increase, e.g. unnecessary duplication of management roles

  • There can be a culture clash between the two firms that have merged

3. Conglomerate integration

  • This is a merger or takeover between firms in entirely different industries

    • E.g. An ice cream manufacturer buys a clothing company

Evaluating conglomerate integration

Advantages

Disadvantages

  • Spreads risk across industries

  • Uses surplus cash and skills elsewhere

  • Key expertise, such as strong financial management or marketing know-how, can be shared with all part of the business

  • Limited management know-how in unfamiliar sectors

  • Research may be required to understand trends and customer needs

  • Greater organisational complexity

Mergers

  • A merger occurs when two or more companies combine to form a new company

    • The original companies cease to exist and their assets and liabilities are transferred to the newly created entity

  • Firms merge to become stronger together than they would be apart

    • That strength comes from lower costs, more customers, new capabilities or less competition

Examples of recent UK mergers

Explanation

  • Both companies said the cost of rolling out 5G was too big for them to handle alone

  • By joining forces they can

    • pool their money to pay for new 5G masts and fibre cables

    • save £700 million a year by sharing towers, shops and support staff instead of running two separate networks

    • become a strong brand that can compete on price and coverage with the two bigger rivals, BT’s EE and Virgin Media O2

  • Virgin Media had the fastest home broadband, while O2 had one of the biggest mobile networks

  • Putting them together allows the new firm to

    • sell bundles that give customers fast home internet and mobile service on one bill

    • share the cost of upgrades to cables and 5G over several years

    • Increase profit by £540 million a year within five years by using the same call centres, shops and marketing

Takeovers

  • A takeover occurs when one company purchases another company, often against its will

    • The acquiring company buys a controlling stake in the target company's shares (>50%) and gains control of its operations

Reasons for mergers and takeovers

Reason

Explanation

Example

Economies of scale

  • Joining two firms lets them combine production facilities, networks, and support functions

  • Fixed costs are spread over more units and duplicated activities are eliminated

  • The result is a lower average cost per unit and higher profit potential

  • The 2020 T-Mobile and Sprint merger created synergies of at least $43 billion by merging networks and closing down duplicate sites

  • This made it cheaper to roll out its nationwide 5G service

Rapid entry into new markets or segments

  • Instead of building a presence from scratch, a firm can acquire another that already has customers, stores, or distribution channels in the desired market

  • This saves time and reduces risk

  • The Amazon and Whole Foods merger in 2017 instantly created Amazon a physical retail presence and a premium grocery brand

Acquire capabilities or technology

  • A merger can secure specialist know-how, patents or ways of working that improve a business's product without time-consuming in-house R&D

  • In 2016 Disney paid about $7.4 billion to bring Pixar’s cutting-edge computer-animation talent in-house

  • The merger increased Disney’s animation output and boosted its box-office performance

Reduce competitive pressure

  • Absorbing a fast-growing rival can protect a business's market share and reduce future price competition

  • Facebook merged with Instagram in 2012, preventing a potential challenger from attracting its users

Increased market power

  • A larger market share can improve bargaining strength with suppliers and retailers

  • It may allow the firm to set prices more confidently (within legal limits)

  • Anheuser-Busch's 2016 takeover of SABMiller means that the business produces 30% of all beer sold worldwide, far more than its next largest rival, Heineken

Common issues with takeovers

  • Mergers and takeovers can look attractive, but business leaders must also plan for culture clashes, higher debt and the real possibility that regulators will refuse the merger

  1. Hard-to-blend cultures and systems

    • When two very different organisations join together, employees may clash over ways of working and IT systems may be incompatible

    • Managers can spend months fixing problems instead of improving products

    • Expected cost savings and new ideas can stall, leading to poorer performance and lower staff morale

    • E.g. Kraft Foods and Heinz's merger in 2015 led to significant cost-cutting which left some brands under-funded and less able to compete

  2. Heavier debt burden

    • Mergers are often paid for with borrowed money

    • High interest payments use cash that could alternatively fund research, marketing or new factories

    • If profits fall, the enlarged business may be forced to cut dividends, sell assets or issue new shares

    • E.g. Dell borrowed $48 billion in 2016 to finance its purchase of rival EMC, which affected cash flow for years and was a key reason Dell had to raise finance by selling shares on the stock market in 2018

  3. Regulation

    • Competition watchdogs such as the UK's Competition and Markets Authority (CMA) can delay a merger for years, demand that parts of the business be sold off, or block the deal entirely if they think it will hurt consumers

    • Companies can spend years and millions of pounds on planning a merger that is never approved

    • The CMA stopped the planned £12 bn merger of Sainsburys and Asda in 2019, saying it would push up prices for groceries and fuel and limit competition

Joint ventures

  • A joint venture is when two businesses join together to share their knowledge, resources and skills to form a separate business entity for a limited period of time

    • E.g. The mobile network EE is a joint venture formed by the French mobile network, Orange and the German mobile network, T-Mobile

Reasons for joint ventures

Key reasons for joint ventures include spreading risk and securing resources

Problems with joint ventures

  • Conflicting objectives

    • If the parent companies want different things, everyday decisions slow down and the joint venture can lose focus

      • E.g. In 2024 ITV sold its 50% stake in Britbox to the BBC, saying the service would be simpler to run under one owner after the partners’ strategies began to diverge

  • Too small to compete

    • A joint venture that stays small may not have the money, stores or marketing power needed to stand up to larger rivals, so it struggles to grow

      • E.g. In 2016, Sainsburys and Dansk Supermarked's joint venture Netto ended because nationwide expansion would have required more investment than they were prepared to spend

  • Limited control for a minority partner

    • A parent that owns only a small share may have little say in its strategy

      • E.g. Tesco ended its minority stake in its Chinese grocery joint venture in 2020, drawing a line under years of weak performance

Examiner Tips and Tricks

A joint venture is a shared project, not a takeover or venture capital deal

Compare its lower risk and knowledge‑sharing benefits with the loss of some control to show balance

Franchising

  • Franchising is a business model where an individual (franchisee) buys the rights to operate a business model, branding, and support from a larger company (franchisor) in exchange for an initial lump sum plus ongoing fees

  • The franchisee operates the business under the franchisor's established system and receives training, marketing support, and ongoing assistance

Examples of fast food franchises

Evalauating franchise growth

Advantages

Disadvantages

  • Rapid expansion with little capital

    • Franchisees pay most start-up costs, so the parent company can open many outlets without large new loans

  • Motivated local owners

    • Each franchisee has money at stake, so they work hard and know their local customers better than head-office managers might

  • Stronger joint marketing

    • National advertising, brand guidelines and bulk purchasing negotiated by the franchisor give every outlet a bigger presence than it could afford alone

  • Lighter day-to-day management workload

    • The franchisor focuses on branding, supply chains and support while franchisees run daily operations

  • Less direct control

    • If a franchisee cuts corners, product or service quality can fall and damage the whole brand

  • Shared profits

    • A share of each outlet’s revenue stays with the franchisee, so the franchisor earns less per unit than from company-owned stores

  • Risk of conflict

    • Disputes over fees, franchise territories or new policies can arise and may require costly legal or management time to resolve

  • Ongoing training and support costs

    • The franchisor must provide initial training, audits and continual guidance to keep standards consistent across all outlets
