Zug ZG/Zürich, December 2025

Swiss Prime Site has acquired a new office property on Pfingstweidstrasse in Zurich-West, as detailed in a press release. The property, which has a rental area of 19,000 square meters and a net yield of 3.8 percent, is already fully let to the stock exchange operator SIX Group Services AG.

The acquisition marks the last major investment of the CHF 300 million capital increase for growth investments from last February. In April and August, Swiss Prime Site had already used the funds to acquire office properties in Geneva and Lausanne. All new acquisitions generate yields that are significantly higher than the portfolio yield and increase the net asset value (NAV) per share as well as the funds from operations (FFO) per share.

Swiss Prime Site and the private seller have agreed not to disclose the purchase price of the property. Due to the recent year of construction, the sustainable construction method and the office building’s district heating connection, Swiss Prime Site expects a BREEAM sustainability rating of “very good”.

“The transaction underscores our focus on first-class, centrally located office properties and shows how agile we are in deploying fresh capital for sustainable growth. It is particularly pleasing that we were able to acquire this prestigious property – used by the Swiss stock exchange as our country’s central infrastructure – as part of an exclusive purchase review and thanks to the trusting cooperation with the seller”, René Zahnd, CEO of Swiss Prime Site, is quoted in the press release.

With the three acquisitions made and a reduction in the planned property sales as part of capital recycling, Swiss Prime Site expects an increase in rental income of CHF 20 million from 2026. The transaction was completed on December 1, 2025.
