The transaction highlights the team's strengths in financial institutions, regulatory matters and the establishment of new lending platforms.

The firm advised Sixth Street on the Swiss law aspects of its US$300 million structured equity and growth debt investment in Essential Pharma, as part of the company’s wider €900 million recapitalisation. The transaction showcases the team’s expertise in sponsor-backed financings, cross-border security structures and sophisticated private capital solutions in the healthcare sector.
