Through a simple policy change, the European Commission (“Commission”) now has greater scope to assert jurisdiction over transactions that fall below the EU or Member States merger filing thresholds. In combination with the United Kingdom’s expansive interpretation of its “share of supply” jurisdictional test, the Commission’s new policy turns European merger control into an increasingly unpredictable risk factor in cross-border deals that fall below the bloc’s filing thresholds. This is a noteworthy development in one of the most prominent merger control regimes.
