Corporate mergers occur when two or more companies combine to form a single entity. This process can help businesses grow, reduce competition, and achieve economies of scale. Mergers can take various forms, including horizontal mergers, where companies in the same industry join forces, and vertical mergers, where companies at different stages of production collaborate. The reasons behind corporate mergers often include the desire to increase market share, access new technologies, or expand into new markets. Successful mergers can lead to improved efficiency and profitability, but they can also face challenges such as cultural differences and regulatory scrutiny from government bodies like the Federal Trade Commission.
