Which of the following best describes vertical integration?

• A. Two businesses from different sectors become one business
• B. Two businesses operating in the same market merge to grow
• C. A company sells off a non-core asset
• D. A firm outsources a function

Answer: (A)

Vertical integration happens when a company extends its control over more stages of its own value chain, either moving backward into its inputs by buying suppliers or forward into distribution by owning channels to customers. It’s about owning multiple steps in the production and delivery process, not just combining with another firm.

Merging with a business from a different sector describes diversification into unrelated activities, creating a conglomerate rather than extending control over the same production-distribution chain. Merging with another firm in the same market describes horizontal integration—joining competitors at the same stage of production. Selling a non-core asset is divestment, reducing the range of activities. Outsourcing a function reduces internal control by shifting work to external providers.

So, none of these options truly describe vertical integration; the correct idea would be a firm acquiring or merging with its supplier or its distributor within its own value chain.
