Horizontal mergers can lead to economies of scale, increased market power, and the ability to eliminate competition. By combining two companies that operate in the same industry, the merged entity can benefit from cost savings and increased efficiency. On the other hand, vertical mergers can result in better control over the supply chain, reduced transaction costs, and improved coordination between different stages of production.
