Castellum AB ( (SE:CAST) ) has issued an update.
Castellum has secured a 15-year lease for the entire 24,000-square-metre Infinity office property in Hagastaden, Stockholm, which is currently under construction and scheduled for completion by the end of 2027. The unnamed tenant, which has opted to remain confidential, holds a unilateral right until 1 June 2026 to scale back its commitment to half the space on a shorter five-year term, meaning the final scope of the lease will not be fully confirmed until that option period expires; nonetheless, the agreement marks a significant pre-letting for Castellum’s Sorbonne 1 project and supports the company’s growth and occupancy prospects in a key Stockholm development area.
The most recent analyst rating on (SE:CAST) stock is a Buy with a SEK135.00 price target. To see the full list of analyst forecasts on Castellum AB stock, see the SE:CAST Stock Forecast page.
