Warteck Invest AG is a publicly listed real estate company based in Basel, Switzerland, engaged in the ownership, development, and management of a diversified property portfolio. The company's business model spans the entire real estate value chain, from property acquisition and project development to long-term leasing and facility management. Warteck Invest generates the vast majority of its revenue from rental income derived from its portfolio of over 65 residential, commercial, and mixed-use properties spread across 11 Swiss cantons. The portfolio, valued at over CHF 1 billion, is strategically concentrated in economically strong regions of German-speaking Switzerland, including Basel, Zurich, Zug, and Lucerne. The company focuses on a buy-and-hold strategy, creating value through active property management, repositioning, and sustainable upgrades, with a growing portion of its buildings heated by renewable energy. Originally established in 1856 as a brewery, the real estate operations were spun off into an independent entity in 1988. Today, Warteck Invest maintains a lean operational structure and caters to a diverse tenant base of households, retailers, and corporate offices.
