We are specialists across the full range of Antitrust, Competition and Trade matters. We have expert sub-groups specialising in specific areas within the wider competition and trade field, e.g. for State aid and FDI/Foreign investment screening. We are also well-known as experts in various sectors of the economy. Our renowned sector specialisation encompasses automotive, consumer products/FMCG, construction, digital economy, energy/oil & gas, life sciences, telecommunications/media and transport to name but a few. 

Our clients range from many large multinationals who frequently use our team as their ACT law firm of choice for the entire region (e.g., in Europe or CEE), to governments at all levels and a high number of medium-sized companies. We also advise Turkish brand owners and leading market players, as well as local governmental entities. We represent them before Turkish authorities, including the Turkish Competition Authority (Rekabet Kurumu), as well as Turkish courts.

We use the most up-to-date technical and AI tools to support our business in Türkiye and abroad.

We hold a renowned annual EU competition law conference which has become a feature in the Brussels calendar.  We put out regular case law updates on Turkish, European and international competition and trade developments on our Law Now service. Our monthly EU law webinars are attended by in house counsel from around the world and by renowned Turkish companies. And our group is steered, not just by a management committee of partners but also by an active associates’ group that keeps us innovating to serve clients.
