In a recent blog post where we reflected on DG Competition fining Altice a record € 124.5m for gun-jumping, we already anticipated the Ernst & Young P/S v Konkurrenceradet judgment where, for the first time, the Court of Justice of the EU (CJEU) provides guidance on the scope of the standstill obligation under the EU merger control regime. That judgment was handed down on 31 May. According to the CJEU, the “gun-jumping” prohibition only covers actions contributing to a change of control of the target undertaking. Because KPMG DK’s pre-clearance termination of its cooperation agreement with KPMG international did not contribute to Ernst & Young (EY) acquiring control over KPMG DK, EY and KPMG DK did not infringe the gun-jumping prohibition. This marks a welcome line in the sand finally indicating a limitation on the gun-jumping prohibition for merging companies.
