The facility, to be built in Visp, Switzerland, will be established through a joint venture with an initial investment of around CHF290m shared equally between Sanofi and Lonza.

The Walder Wyss team included Luc Defferrard (partner, M&A), Michael Isler (partner, IPIT), Ramona Wyss (managing associate, M&A IPIT), Tina Hurni (associate, real estate) and Alexandra Brenner (associate, real estate).
