Oliver Geiss focuses his practice on competition and foreign direct investment (FDI) laws in the EU and Germany. He is a member of the firm’s Global Board and actively supports its DEI initiatives in a leading role.

Oliver regularly advises clients on merger control and FDI notifications of cross-border transactions worldwide and has extensive experience in a variety of industry sectors, including chemicals, automotive, energy and pharmaceuticals. He also leads our German merger control and FDI practice, as well as has extensive experience in well over 100 filings with German regulators – from straightforward acquisitions to complex second phase cases.

Comments in directories like Legal 500 highlight the added value Oliver brings to transactions (“thanks to his contributions, we were able to complete a very challenging project on time”), and state that they “would recommend him to anyone” and elicit praise for his expertise and responsiveness over different time zones.

He has also represented companies in some of the largest cartel investigations before the European Court of Justice, the European Commission and the German Federal Cartel Office, including Airfreight, LCD Screens, Optical Disc Drives, Refrigeration Compressors and Industrial Batteries, as well as in civil damage actions before national courts. Oliver is at the forefront of developments and regularly publishes in this area.

He frequently advises clients on EU State Aid law, including before the European Court of Justice, and the EU Foreign Subsidies Regulation as well as competition law aspects of commercial agreements, such as distribution agreements or joint buying or selling arrangements.
