Dr. Katharina Weiner

Katharina specializes in transactional public law and advises global clients and the public sector on reorganizations, project developments and M&A transactions. With her focus on regulatory and public law aspects (e.g. sustainability, supply chain compliance and ESG/EHS), Katharina has extensive experience and expertise in structuring, implementing and managing cross-border reorganizations in highly regulated sectors (in particular healthcare, IT, infrastructure and transport as well as defense and security), where she regularly takes on the cross-sector coordination.

Katharina's practice also includes advising on subsidy and EU state aid law aspects, in particular in connection with investment projects in Germany. She advises on all phases of project development, from site selection and project structuring to the structuring of the legal framework for subsidies and the contractual implementation of the project.

In addition, Katharina focuses on supporting globally active companies as well as governments and state institutions with major projects affecting the public sector. She advises and represents bidders and contracting authorities in procurement and review proceedings.
