Thilo-Maximilian Wienke

Local Partner, Düsseldorf



Thilo offers a unique combination of international merger control expertise and German FDI experience in international transactions, coupled with a relentless client service attitude.

Thilo advises international investors in the area of German investment control and handles a wide range of review proceedings at the BMWK in a broad spectrum of sectors (from energy/critical infrastructure to high-tech and pharmaceuticals to raw materials and defense), and coordinates multijurisdictional FDI proceedings. In addition, Thilo advises on German, as well as EU competition law, including merger control proceedings, distribution cartel law and vertical behavior, classic cartels, as well as on market dominance and comparable constellations. He regularly works closely with White & Case's energy law practice and advises on transactions (merger control and investment control) in the energy infrastructure sector.

In addition to its transactional activities, Thilo has experience in distribution law matters. He was involved in the revamp of a number of leading German and international branded goods manufacturers' selective distribution networks, and advises regularly on vertical conduct.

Prior to joining White & Case, Thilo worked for another renowned US law firm in Cologne and Brussels, focusing on German and European antitrust law. During this time, he was involved in a number of high-profile merger control proceedings.

Based on his merger control experience during the early stages of his career and relentless client service attitude, Thilo soon identified a growing need to offer clients coordinated advice regarding the two main regulatory requirements in international transactions – merger control and FDI. FDI advice has since become an integral part of Thilo's practice while retaining a strong stance in merger control and antitrust matters, offering seamless "one-stop-shop" regulatory advice to clients and colleagues. As a father of three, coordinating conflicting positions is also an integral part of Thilo's personal life – providing valuable insights for navigating novel challenges of any kind.
