The story

The company was founded in 1999 by the pension funds of Credit Suisse and Siemens Switzerland and the then Winterthur Life (now Axa). Swiss Prime Site was listed on the SIX Swiss Exchange in April 2000. At the time, the real estate portfolio had a value of around CHF 500 million.

In 2001, Swiss Prime Site bought a portfolio of office buildings from Swisscom. In 2003, it acquired the Frey Group and in 2004 Maag Holding AG. In 2009, the takeover of the stock listed Jelmoli Holding AG took place. In October 2012, Swiss Prime Site acquired Wincasa AG, a real estate service company in Switzerland, as well as the Tertianum Group. In 2019 Swiss Prime Site announced the sale of the Tertianum Group. At the end of 2021, Swiss Prime Site acquired the Akara Group, and in the beginning of 2024 the asset manager of Fundamenta Group, to strengthen the Services segment. In March 2023, the sale of Wincasa to Implenia was announced.
