Should regulators block corporate mergers that create high levels of market concentration?

The New Jersey attorney general has filed a formal complaint to block CRH from acquiring Arcosa’s hot-mix asphalt business. The legal challenge targets the merger’s potential to limit competition for contractors in central New Jersey.

Why it matters

The move signals increased state-level oversight of consolidation in specialized infrastructure markets. Operators in construction should monitor this trend, as the state claims the deal would drive up costs and enable price coordination among local producers.

The attorney general reports that CRH and Arcosa control 75 percent of the market for Department of Transportation-approved hot-mix asphalt in central New Jersey. This high concentration is the primary basis for the state’s legal challenge against the merger.

The players

CRH

A global building materials company with extensive operations in aggregates, cement, and asphalt products.

Arcosa

A manufacturer of infrastructure-related products and solutions that is looking to divest its hot-mix asphalt business.

New Jersey Attorney General

The state's top law enforcement official responsible for enforcing antitrust statutes and consumer protections.

The details

The state alleges that combining these two major entities would diminish competition for critical infrastructure materials, likely resulting in higher costs for road-building projects. By seeking to block the acquisition, the attorney general aims to prevent potential market coordination among producers that could arise from the consolidated ownership of asphalt plants in the central region.

Market Landscape

This litigation follows the state's established pattern of using the New Jersey Antitrust Act to challenge horizontal mergers that exceed regional concentration thresholds. The state's intervention marks a departure from typical industry consolidation, focusing on the specific leverage held by firms supplying DOT-approved materials.

Construction firm owners should review their supply contracts and pricing forecasts, as the state's legal action could create uncertainty regarding the availability of approved asphalt sources. Contractors may need to develop contingency procurement plans if the merger is delayed or permanently blocked.

The takeaway

The case highlights the heightened regulatory scrutiny facing firms that control significant portions of state-regulated material supply. Operators should monitor the progress of this filing, as it directly impacts market pricing and competitive landscape for regional infrastructure work.
