Antitrust Guidelines Revised

The revised antitrust guidelines reflect a shift toward assessing broader competitive harms, including effects on wages, innovation, and supplier independence. Agencies now explicitly consider how concentration in labor markets can suppress compensation and reduce job mobility. This marks a departure from decades of precedent focused primarily on consumer prices and efficiency gains.

The updates sharpen criteria for digital platform reviews, aiming to address self-preferencing, data accumulation, and barriers to multi-homing. Regulators will more closely examine whether dominant firms leverage one market position to gain unfair advantage in adjacent sectors. The guidelines also lower the threshold for examining serial small acquisitions that collectively build market power.

Companies must now reevaluate transaction strategies with these new lenses in mind. Deal teams are adjusting due diligence to include labor market analysis and ecosystem interdependence assessments. Legal teams increasingly stress-test proposed integrations against the updated framework before filing notifications.

The guidance does not carry the force of law but informs prosecutorial discretion and litigation strategy. Courts have historically relied on such guidelines when interpreting statutes. Stakeholders expect the revised approach to influence both pre-merger consultations and post-merger enforcement priorities going forward.
