The main objective of corporate mergers is to enhance economies of scale. When companies merge, they can combine their resources, reduce duplication of efforts, and operate more efficiently. This can lead to cost savings, improved productivity, and increased profitability. By merging, companies can also expand their market share, increase their bargaining power, and access new technologies or products. While mergers can also provide financial advantages, such as increased revenue or reduced costs, the primary goal is to create a stronger, more competitive business entity through economies of scale.
