Sergiy Glushchenko has nearly 20 years of experience providing international and Ukrainian clients with comprehensive advice across the full spectrum of competition law.

 

He regularly acts as Ukrainian competition counsel on major cross-border transactions and has advised on more than 300 merger control matters, including over 10 Phase II investigations, across sectors such as consumer goods, technology, media, aviation, automotive, pharmaceuticals, energy and financial services. His experience includes successfully defending clients in gun-jumping investigations and securing precedent-setting decisions on the geographic allocation of turnover that closely align with EU merger control principles.

 

Beyond merger control, Sergiy advises on antitrust investigations, abuse of dominance, restrictive agreements, distribution and pricing practices, competition compliance, consumer protection and related regulatory matters. His experience also includes state aid, competition litigation and internal investigations involving suspected fraud, corruption, conflicts of interest and other corporate misconduct.

 

Alongside his private practice, Sergiy has supported the Ukrainian Government in aligning national legislation with EU law, with a particular focus on competition and digital regulation. In that role, he has engaged directly with the European Commission through technical discussions, TAIEX meetings and other exchanges concerning the approximation and implementation of EU competition, Digital Markets Act and Digital Services Act rules.
