Horizontal Merger vs. Vertical Merger: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on March 2, 2024
A horizontal merger involves companies at the same stage in the same industry, while a vertical merger is between companies at different stages of the same supply chain.

Key Differences

Horizontal mergers occur between companies operating at the same level within the same industry, often competitors. Vertical mergers involve companies at different stages of production or supply chain within the same industry.
Horizontal mergers aim to increase market share, reduce competition, or achieve economies of scale. Vertical mergers seek to streamline operations, control more of the supply chain, or reduce production costs.
A horizontal merger can change competitive dynamics by consolidating market power. A vertical merger, however, may lead to increased efficiency and control over supply and distribution channels.
Horizontal mergers are often closely scrutinized for antitrust concerns, as they can lead to reduced competition. Vertical mergers, while also reviewed, typically face less antitrust scrutiny unless they create barriers to market entry.
A horizontal merger example is two competing smartphone manufacturers merging. A vertical merger example is a car manufacturer merging with a tire supplier.
