We act as independent advisers and monitors during and after merger control and national security reviews, as well as antitrust, state aid, consumer protection, and other regulatory investigations.

Heightened regulatory scrutiny to uphold market competitiveness and national security can result in structural or behavioural obligations, and the imposition of an independent monitor to oversee compliance.

Understanding your business and its obligations, we focus on areas important to regulators and provide recommendations on demonstrating compliance to minimise the risk of issues. We help you manage compliance cost-effectively and resolve issues quickly to present a comprehensive picture.
