As 2025 draws to a close, we have continued to see significant developments across a range of areas of EU and UK competition law.

From an EU perspective, we reflect on the European Commission's renewed focus on vertical restraints over the last 18 months, discuss the Court of Justice's latest "pay for delay" ruling in Modafinil, and examine the Commission's evolving decisional practice under the Foreign Subsidies Regulation (FSR), in view of its recent conditional clearance in ADNOC/Covestro.
