Sustainable Digitalization And Urbanization Will Drive Nordic Real Estate

Key Takeaways

• Prime project locations, strategic acquisitions, and focus on sustainability position Castellum for higher asset values, recurring rental growth, and enhanced earnings.
  
• Early technology adoption, flexible workspace offerings, and reinvestment of non-core assets drive market share gains and support industry-leading earnings expansion.
  
• Structural decline in office demand, elevated regulatory and financial burdens, and heavy geographic concentration are amplifying Castellum's revenue volatility and long-term earnings risk.

Catalysts

Castellum is one of the Nordic region’s largest commercial property companies, with a focus on office and logistics properties in Nordic growth cities.

• Analyst consensus sees Castellum's project development in prime locations as a revenue driver, but with the company accelerating project launches and capitalizing on urbanization in major Nordic cities, there is potential for rental income and asset values to exceed expectations, especially as population growth magnifies office and logistics demand in these regions.
  
• While analysts broadly expect the Entra acquisition to strengthen Castellum's portfolio and earnings, the move also positions Castellum for outsized earnings accretion as it doubles down on Oslo's premium office market, purchases assets at a material discount to net asset value, and exercises greater influence over a portfolio weighted toward long government leases and blue-chip tenants.
  
• As Castellum commits to net zero emissions by 2040 and upgrades energy efficiency at scale, it stands to benefit disproportionately from tightening sustainability regulations, unlocking higher asset valuations, lower operating costs, and a persistent rental premium from sustainability-minded, long-term corporate and public sector tenants-bolstering both top-line growth and net margins.
  
• Castellum's early adoption of smart property technology, investment in a more proactive and AI-driven leasing organization, and ability to offer flexible workspace solutions put it at the forefront of shifting tenant preferences, which is likely to accelerate market share gains and drive above-market rental growth, supporting recurring revenue and higher occupancy over time.
  
• The company's active reinvestment strategy, focused on cycling proceeds from non-core asset sales into high-yield, high-demand development projects-combined with a strong balance sheet, low leverage, and access to green financing-sets the stage for significant expansion of funds from operations and industry-leading earnings growth in a recovering economic environment.

Castellum Future Earnings and Revenue Growth

Assumptions

• This narrative explores a more optimistic perspective on Castellum compared to the consensus, based on a Fair Value that aligns with the bullish cohort of analysts.
• The bullish analysts are assuming Castellum's revenue will grow by 1.8% annually over the next 3 years.
• The bullish analysts assume that profit margins will increase from 25.4% today to 73.3% in 3 years time.
• The bullish analysts expect earnings to reach SEK 7.7 billion (and earnings per share of SEK 14.07) by about July 2028, up from SEK 2.5 billion today. The analysts are largely in agreement about this estimate.
• In order for the above numbers to justify the price target of the more bullish analyst cohort, the company would need to trade at a PE ratio of 11.7x on those 2028 earnings, down from 22.7x today. This future PE is lower than the current PE for the GB Real Estate industry at 19.5x.
• Analysts expect the number of shares outstanding to remain consistent over the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 8.74%, as per the Simply Wall St company report.

Castellum Future Earnings Per Share Growth

Risks

• Secular shifts toward remote work and digitalization are suppressing long-term demand for traditional office space, which is Castellum's largest segment, and this trend is already reflected in the company's 1% decline in occupancy rate and negative net leasing, putting future recurring rental revenues under structural pressure.
  
• Persistent over-supply in certain real estate segments, particularly offices, is leading to increased vacancies, lower rental growth, and higher tenant incentives as seen in Castellum's negative net leasing of minus SEK 184 million and reported decreased NOI, signaling weaker revenue and rental yields.
  
• Stricter environmental regulations and accelerated green transition requirements are raising compliance and capex burdens, as Castellum's own commitment to achieve net zero emissions by 2040 (validated by the Science Based Targets initiative) will require substantial long-term investment in property upgrades, likely weighing on future free cash flow and net margins.
  
• Concentration in the Swedish and Nordic markets exposes Castellum to local economic downturns and regulatory risks, as evidenced by the negative impact from tenant bankruptcies (such as Northvolt) and business relocations out of Sweden, amplifying potential revenue volatility and earnings risk.
  
• The company's recent trend of divesting stable yielding assets and investing heavily in new projects and acquisitions, while increasing leverage and refinancing activity, heightens financial risk-especially if interest rates remain volatile, which could increase interest expenses, hampering net profits and constraining future investment capacity.

Valuation

• The assumed bullish price target for Castellum is SEK142.9, which represents two standard deviations above the consensus price target of SEK114.4. This valuation is based on what can be assumed as the expectations of Castellum's future earnings growth, profit margins and other risk factors from analysts on the bullish end of the spectrum.
• However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of SEK150.0, and the most bearish reporting a price target of just SEK98.0.
• In order for you to agree with the bullish analysts, you'd need to believe that by 2028, revenues will be SEK10.6 billion, earnings will come to SEK7.7 billion, and it would be trading on a PE ratio of 11.7x, assuming you use a discount rate of 8.7%.
• Given the current share price of SEK116.8, the bullish analyst price target of SEK142.9 is 18.3% higher.
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
