Castellum says it aims to catalyze climate-neutral urban property, turning real estate from an emissions source into a proactive climate solution.

Castellum strategic principles prioritize long-term value creation through sustainability, risk-aware growth, and high-quality property management across 5.3 million sqm of leasable area and a portfolio value of approximately SEK 158 billion at year-end 2025.

What Future the Company Is Trying to Shape: Castellum aims to shape a future where the real estate sector is a proactive component of the climate solution rather than a passive contributor to emissions. Its vision centers on becoming the most attractive and sustainable property partner in the Nordic region. This is not merely aspirational; Castellum was the first European property company to have its climate targets approved under the Science Based Targets initiative (SBTi) new Buildings Sector Criteria in 2025. The company is driving toward net-zero greenhouse gas emissions across its entire value chain by 2040, aiming to transform its 5.3 million square meters of leasable area into high-performing, climate-neutral environments that set the benchmark for institutional-grade real estate.

Strategic pillars: sustainability-led asset optimization; disciplined capital allocation; urban development and mixed-use leasing; digital operations and tenant experience; and robust governance and stakeholder engagement aligned with Castellum governance principles and corporate governance and stakeholder relations.

Key metrics 2025: rental income SEK 10.8 billion, net operating income (NOI) SEK 7.2 billion, EPRA net tangible asset value per share SEK 184, loan-to-value (LTV) 37%, and like-for-like rental growth +3.6%.

How Castellum's strategy affects investors: sustainability-driven cashflow resilience reduces vacancy risk and strengthens pricing power; targeted urban development projects produce stabilization yields above portfolio average; LTV 37% and diversified financing lower refinancing risk.

Implementation: SBTi-aligned retrofits and new-builds, energy efficiency upgrades reducing operational emissions, district heating and electrification investments, tenant engagement programs to cut Scope 3 emissions, and performance KPIs tied to management compensation to ensure accountability for Castellum sustainability strategy and Castellum real estate strategy.

Risk controls: geographic concentration in Sweden balanced by strong tenant mix; interest rate sensitivity managed via fixed-rate debt and hedging; climate-transition risk addressed through climate-proofing assets and a 2040 net-zero target-if deep retrofit timelines slip beyond 10 years, asset obsolescence and value impairment risks rise.

Competitive advantages: large, modern portfolio enabling scale efficiencies; early SBTi Buildings Criteria approval creating differentiation in ESG screens; integrated development-to-operations model that accelerates value creation and supports Castellum property portfolio management approach and Castellum growth strategy in Sweden.

Investor takeaways: consider Castellum company strategy as a sustainability-first, low-risk growth play with measurable KPIs-valuation sensitivity centers on cap rate compression, rental growth, and execution of retrofits that unlock higher NRI and lower operating emissions.
