A merger unites firms at different stages of related businesses?

A merger that unites firms at different stages of related businesses is known as a vertical merger. This type of merger typically involves a company acquiring another that operates at a different level of the supply chain, such as a manufacturer merging with a supplier or distributor. Vertical mergers can enhance efficiency, reduce costs, and improve supply chain management by streamlining operations and consolidating resources. Additionally, they can provide firms with greater control over the production process and access to new markets.
