Bull points
- Several large leases have been signed during the second quarter. One of them in Gothenburg, we have leased out an entire building for 500 co-workers to Saab on a long lease. The building will be adapted for Saab's needs and completed in June 2026. The existing tenant will move to a smaller building also owned by Castellum and the total deal generates 17 million in positive net leasing.
- Yearly rent value, 23 million. Also in Gothenburg, our tenant, Nitech, after merger with Semcon, leases the entire building. Total area, 9,288 square meters. That will host 500 coworkers with a rental value of 27 million per year.
- we have refinanced approximately 10 billion of secured debt during the quarter with an annual cost saving of around 20 billion SEK, million SEK. Current credit spreads of commercial papers is only 45 bps on a three-month tenor, relatively cheap money and good for our cash management.
Bear points
- The direct property cost for the like-for-like portfolio increased by SEK 14 million, equivalent to 1.2%. Direct property costs decreased at the beginning of the year due to the warm winter, but increased in the second quarter, primarily due to the higher rental losses, which increased by CX 17 million from CX 8 million to 25 million.
- castellan has written down property values with approximately 1.15 billion, equivalent to minus 0.8%. The value chains is partly driven by the default north hold. The fact that Ofri will leave approximately 24,000 square meters in Solna and generally lower cash flow expectations in our valuations due to a downward pressure on rental levels and or increased TI's.
- So summarizing the first half year results compared to the same period last year is negatively affected by the fact that we have sold standing and yielding assets during last year, as well as being hurt by higher vacancies. In addition, income from property management is negatively affected by slightly higher financial costs.
