Horizontal Integration are referring to a strategy in which a firm acquires similar firms to increase its market share and profits. It can lead to monopoly if a company captures the vast majority of the market for that product or service. It is orthogonal to vertical integration, where companies integrate multiple stages of production of a small number of production units. Horizontally integrated companies are able to gain market share because they have access to the customers of the company they acquired.
