Markus advises clients on European and German competition law. He defends companies in cartel cases, which may entail very substantial fines that can sometimes pose a threat to a company's financial viability. Recently, Markus was involved in several of the European Commission’s automotive parts and capacitor cases. Markus has substantial expertise with respect to leniency applications and settlement negotiations, both at a European and German level, and litigation before the European courts in Luxemburg. Markus frequently advises clients in merger control cases before the European Commission and the Federal Cartel Office, and coordinates merger control approval processes for them world-wide. Recent high-profile work includes the European Commission Phase II investigations of Knorr-Bremse’s proposed acquisition of Haldex and E.ON’s takeover of innogy. Over the years, Markus has assembled broad expertise in the insurance and insurtec sectors. He is a trusted competition law and merger control advisor to many insurance companies. Recently, he acted for Generali (sale of the life insurance business to Viridium) and for AXA (restructuring of ROLAND).


Markus is admitted to the German bar (2004) and New York bar (2007). He joined Hengeler Mueller in 2004, and has been partner at Hengeler Mueller since 2009. He is based in Hengeler Mueller's Brussels and Düsseldorf offices.

Competition: EU and global

Within: Competition: EU and global

At Hengeler Mueller, Hans-Jörg Niemeyer and Markus Röhrig, who are the main contacts in Brussels, act for a broad base of German, European and non-European clients. Working closely with colleagues based in Germany, the duo excel in defending clients' interests in cartel investigations brought by the German Federal Cartel Office, the EC and foreign antitrust authorities. Elsewhere, the team assists clients with parallel US and European merger reviews, and also plays a key role in other global mergers. The firm has been acting for MAN SE in various follow-on actions arising from the EC's truck cartel investigation. Tata Steel, Knorr-Bremse and Carl Zeiss Vision are also active clients.

Within: Antitrust

Recognised for being ‘unparalleled in antitrust law’, Hengeler Mueller offers ‘plenty of experience and excellent guidance’ for a broad client portfolio, which includes renowned German and international companies in equal measure. One area of specialism is fine proceedings which often have an international component. Markus Röhrig represented Japanese company Calsonic Kansei in EU fine proceedings relating to vehicle air-conditioning and engine cooling systems. The ‘pragmatic’ Thorsten Mäger succeeded in gaining full immunity from fines for MAN in connection with lorry antitrust proceedings on the basis of a leniency application, and the instruction still includes defence against claims for damages within the EU and beyond. It also defends Jacobs Douwe Egberts against claims for damages. The ‘very experienced’ Christoph Stadler and Thomas Paul defend the client against claims of the insolvency administrator of Schlecker. Flagship instructions in merger control law include acting for Knorr-Bremse in phase-II proceedings related to the takeover bid for Haldex, as well as advising Carl Zeiss Vision, as an intervening party, on the proposed merger between Essilor and Luxottica. Internal investigations are another strength and the group advises the Bosch Group on emissions with regard to diesel vehicles. Ralf Willer, who specialises in dispute settlement, was made counsel.
