Castellum (OM:CAST) Stock Faces Interest Coverage Risk Despite Q2 2026 Earnings Delivery

Castellum (OM:CAST) has put fresh numbers on the table for Q2 2026, with revenue of SEK 2,420 million and Basic EPS of SEK 1.37. This helps set the tone for how investors will read the latest quarter. The company has seen quarterly revenue move between SEK 2,420 million and SEK 2,777 million over the past six reported periods, while Basic EPS has ranged from near zero to SEK 2.66. This gives important context for how the current run rate feeds into trailing 12 month EPS of SEK 5.54. With a trailing net profit margin of 28.5%, the focus now turns to how sustainable these margins look given the mix of risks and earnings drivers in play.

Margins, One Offs and Castellum’s 28.5% Profitability

• Casting back over the last 12 months, Castellum generated SEK 9,396 million in revenue and SEK 2,679 million in net income, which works out to a 28.5% net margin compared with 25.8% in the prior year.
• Supporters of the bullish narrative point out that this solid margin sits alongside trailing EPS of 5.54 SEK and only a 1% earnings increase, while:
  • There is a SEK 828 million one off loss in that period, so underlying profitability could look different once that drops out of the numbers.
  • Bulls also argue that projects and acquisitions could push earnings ahead of recent trends. This would further test how sustainable a near 30% margin really is.

Interest Coverage Concerns Versus Bullish Growth Story

• Castellum’s trailing P/E sits at 22x, roughly double both the Swedish real estate industry average of 11.4x and the peer average of 11.2x, at the same time as interest payments are described as not well covered by earnings.
• What stands out against the bullish narrative is that investors are paying this higher multiple while:
  • Interest coverage is flagged as a major risk, which means any pressure on earnings or cash flow would matter more than it might for a less indebted real estate company.
  • Bulls expect stronger rental growth and cash flow over time, but today’s weak coverage means the balance sheet needs to carry that story without much room for error.

For readers who want to see how supporters of a more optimistic view connect these earnings to long term rental growth and acquisitions, including Entra exposure, it is worth checking how their full thesis stacks up against the numbers in this report 🐂 Castellum Bull Case

High Valuation, Modest Trailing Growth and Bearish Concerns

• Over the last year, earnings grew 1% while the stock trades on a 22x P/E against a DCF fair value of SEK 51.44 and an analyst price target of SEK 134.09, compared with a current share price of SEK 130.00.
• Skeptics highlight that this pricing comes with several pressure points in the cautious narrative, since:
  • Revenue is expected in the data to decline about 3.4% a year over the next three years even as forecasts point to roughly 17% annual earnings growth. This creates a clear gap between top line and profit expectations.
  • The past year also includes the SEK 828 million one off loss and weak interest coverage, both of which fit with the bearish focus on refinancing risk, property write downs and office exposure in Nordic markets.
