Drawing on the firm’s wider international presence, Clifford Chance advises on M&A, joint ventures, integrations, and portfolio acquisitions across a variety of sectors, including insurance, energy, life sciences, financial services, and infrastructure. The practice is jointly steered by Christoph Holstein and Jörg Rhiel, both of whom have extensive experience in international M&A, corporate reorganisations, and joint venture structuring. Dominik Heß is adept at handling takeovers, investments in listed companies, and private M&A transactions, as well as matters involving corporate governance, ESG, and reorganisations. In 2025, the team celebrated two partner promotions: Tobias Nogami Kamerling, whose primary focus is energy and infrastructure-specific M&A, and Samuel Frommelt, who assists with cross-border M&A and private equity matters, including carve-outs, add-ons, and minority investments.
