In mergers and acquisitions (M&A), an antitrust review is a process in which competition authorities assess whether the proposed transaction would harm market competition. The goal of this review is to ensure that mergers or acquisitions do not lead to reduced competition, monopolistic behavior, or harm to consumers. Antitrust reviews are an essential part of the regulatory process, and they are typically required before an M&A deal can be finalized. The review process evaluates factors like market share, concentration, and the impact on consumers and competitors.
National Competition Authorities: Different countries have competition or antitrust authorities responsible for reviewing M&A deals. For example, in the United States, the Federal Trade Commission (FTC) and the Department of Justice (DOJ) are in charge of antitrust enforcement. In the European Union, the European Commission reviews mergers for their potential impact on competition.
Global Review: In cross-border transactions, multiple jurisdictions may conduct antitrust reviews, including both national and regional regulatory bodies, depending on the geographic scope of the merger or acquisition.
Antitrust authorities use merger control laws to evaluate whether the proposed merger or acquisition will result in excessive market concentration. This means assessing whether the combined entity would have too much control over a particular market, reducing competition.
Market Definition: Regulators first define the relevant market, which includes identifying the products or services involved, geographic market boundaries, and potential competition concerns.
One of the most critical factors in an antitrust review is the combined market share of the merged entities. If the merger results in a company with a dominant market position, antitrust authorities may view it as potentially harmful to competition.
Regulators will assess whether the merger could reduce competition by eliminating a competitor or creating an entity with enough power to dictate prices, reduce innovation, or hinder consumer choice.
The review process also considers whether new competitors can easily enter the market or whether the merged entity’s dominance would create significant barriers to entry, making it difficult for other players to compete.
Horizontal mergers (between competitors in the same industry) are often more scrutinized than vertical mergers (between companies at different stages of the supply chain) because they have a more direct impact on market competition.
The parties involved in the merger or acquisition must file the proposed deal with the relevant competition authority. The authorities then assess whether the deal raises any concerns.
The initial phase of the review is typically quick, where the authorities analyze whether the merger raises obvious competitive concerns. If there are no significant issues, the deal may be approved.
If the authorities believe the transaction could harm competition, they will move to a more detailed Phase 2 review. This involves a deeper investigation, including gathering additional information, consulting industry experts, and examining potential competitive effects.
In some cases, authorities may seek public comments on the merger or acquisition, including feedback from competitors, customers, and industry stakeholders.
If the competition authority determines that the merger will not significantly harm competition, it may approve the deal without any conditions.
In some cases, the competition authority may approve the deal but impose certain conditions to address competitive concerns. For example, the company may be required to divest part of its business, sell certain assets, or agree to specific behavioral commitments.
If the competition authority finds that the merger would substantially lessen competition, they may block the deal entirely. This typically occurs when the merger would result in a monopoly or reduce competition to the point of harming consumers or other businesses.
Sometimes, the review process can be extended if additional information or complex concerns arise during the investigation.
In 2018, the merger between AT&T and Time Warner was subject to an extensive antitrust review by the DOJ. The DOJ argued that the merger would reduce competition in the media and telecommunications industries, but the court ultimately allowed the merger to proceed without major changes, as the court found no significant competitive harm.
In 2021, the European Commission blocked the merger between two large pharmaceutical companies, Aon and Willis Towers Watson, on the grounds that it would significantly reduce competition in the market for commercial risk and reinsurance broking services.
An antitrust review in M&A is a critical process designed to ensure that mergers and acquisitions do not harm market competition. Antitrust authorities assess the potential effects of a deal on market concentration, competition, and consumers. While most deals pass through the review process with minimal changes, some transactions may be blocked or require modifications if regulators determine that they would lead to reduced competition. Understanding the potential outcomes of an antitrust review is essential for both buyers and sellers in navigating the complexities of M&A deals.
