We have a long and extensive track record of advising clients on merger control requirements and representing them in merger control proceedings. Each year, we notify an impressive number of transactions to the competent competition authorities and coordinate filings worldwide. We cooperate closely with our CMS M&A team, which consistently advises on the most M&A transactions of all law firms in Europe. In addition, many clients entrust us directly with their merger control cases. 

Our widespread footprint — with CMS offices in Europe, Asia, Africa and South America — combined with an extensive network of long-established contacts across all other countries (e.g., via the World Law Group) allows us to offer a one-stop-shop solution to all of our clients’ transactions. CMS Budapest also has broad experience in coordinating CEE-wide merger clearance procedures in various jurisdictions outside the EU as a regional hub.

We help our clients establish an optimal merger control strategy to maximise the prospects of clearance and reduce the risk of delays. We have represented clients successfully in landmark cases, e.g. concerning four-to-three mergers in which they have shaped their industry in major sectors of the economy. Our CMS team in Hungary is also capable of defending our clients’ interests before the courts in cases of an unfavourable event (including in front of the Hungarian Constitutional Court, if necessary). 

On a daily basis we steer our clients through any “gun-jumping” pitfalls in the context of a due diligence process and the preparatory phase between signing and closing. In addition, we set up the necessary safety mechanisms to ensure compliance with competition law during the transaction process (clean teams, data rooms, etc). 

We also represent the interests of third parties to achieve their strategic goals concerning mergers between other industry players.
