GUIDE TO EU MERGER PROCESS
DEADLINES:
The European Commission has 25 working days after a deal is filed for a first-stage review. It may extend that by 10 workingdays to 35 working days, to consider either a company's proposedremedies or an EU member state's request to handle the case.
Most mergers win approval but occasionally the Commission opens a detailed second-stage investigation for up to 90 additional working days, which it may extend to 105 working days.
SIMPLIFIED:
Under the simplified procedure, the Commission announces theclearance of uncontroversial first-stage mergers without givingany reason for its decision. Cases may be reclassified asnon-simplified -- that is, ordinary first-stage reviews -- untilthey are approved.
