Most Popular Narrative: 9.3% Undervalued

Castellum’s most widely followed narrative points to a fair value notably above the current share price, hinting at meaningful upside if growth unfolds as expected. With analyst consensus supporting a higher price target, investor focus is shifting toward key business catalysts and whether recent earnings momentum is sustainable.

The acquisition of additional shares in Entra, resulting in a mandatory offer for remaining shares, is a strategic move intended to strengthen Castellum’s market positioning and earnings by integrating high-quality assets in central Oslo and leveraging long leases. Castellum plans to reinvest proceeds from divested non-strategic properties into refurbishment, tenant improvements, and new project developments. These efforts are anticipated to enhance property values and rental income over time.

Another Perspective: Market Ratios Tell a Different Story

While analysts argue that Castellum is undervalued, the current price-to-earnings ratio of 17.2x is not especially cheap compared to the Swedish real estate industry at 14.8x. It does, however, look much better than the average peer at 36.9x. The fair ratio stands at 31.1x, indicating the market could push the valuation higher in time. Does this make the risk of overpaying for recent momentum more real than it seems?
