The Commission’s Guidelines on abusive exclusionary conduct

03/11/2026

In this Legal Briefing, we present the European Commission’s Guidelines on the application of Article 102 of the Treaty on the Functioning of the European Union to abusive exclusionary conduct by dominant undertakings, published in September 2026, which replace the 2009 Guidance and adopt a more ambitious approach that goes beyond setting enforcement priorities.

One of the key changes is that it is no longer necessary to prove actual effects or harm to consumers. It is sufficient for the conduct to be capable of hindering competitors’ entry or expansion, thereby reducing the burden of proof on authorities and complainants. Exclusivity agreements and loyalty rebates are also presumed to be anticompetitive, and self-preferencing is addressed for the first time. We recommend reviewing your current commercial policies before a competitor, customer or authority does so.
