What Castellum reports on strategy

The company positions its strategy around owning and developing properties in growth cities such as Stockholm, Gothenburg and Malmö, and also in regional centers like Västerås and Örebro, where it sees structural demand for modern offices and logistics space. Management underlines a focus on long-term customer relationships, energy efficiency improvements and modern, flexible premises as key competitive features in a market marked by higher funding costs and selective new construction.

Balance sheet, leverage and interest costs

Castellum’s 2023 report shows that the group faced a higher interest rate environment, translating into increased net financial expenses and pressure on property valuations in the Nordic region. The company disclosed that its loan portfolio is diversified across banks and capital markets, with a mix of bonds and bank loans, and that it manages interest rate risk through a combination of fixed-rate debt and interest rate derivatives.Castellum financial reports and presentations

In its communications, Castellum highlights key financial metrics such as loan-to-value ratio, interest coverage and average debt maturity as central steering parameters for the board. The firm’s strategy includes a commitment to maintain an investment-grade type financial profile over time, which in practice means prioritizing a moderate leverage level, diversified funding sources and proactive refinancing to limit liquidity risk in volatile credit markets.

How Castellum earns its money

Castellum generates most of its revenue from rental income on its office, logistics and community service properties, with tenants ranging from private companies to public sector entities. The company also engages in property development and redevelopment projects, where it invests in new buildings or refurbishments and then either holds the assets for long-term income or sells selected properties to recycle capital.
