Castellum Is Shrinking Its Way to a Higher Share Price

Castellum Is Shrinking Its Way to a Higher Share Price

Castellum's third quarter is not really a quarter story. It is a capital-allocation story. The Swedish landlord has now signed SEK 24.6 billion of disposals this year — the Wihlborgs transaction alone was SEK 13.3 billion and closed on 1 October — and is using the proceeds to do something unusual in European real estate: buy back stock aggressively while shrinking the portfolio. The Alecta transaction closed in September, the AP7 transaction closed in June, and this morning management added another SEK 8 billion to the buyback. It has already spent SEK 7.66 billion this year at an average price just below SEK 123, cancelling roughly 9.9% of the shares. With NAV at SEK 169 per share, the share price is the strategy.

If we can't earn it, we have to return it, like we said in the previous quarter.

That is a coherent answer to a wide discount. It is not an answer to the operating problem.

The portfolio is smaller; the leasing hole is not

The operational core remains ugly. Total net leasing year-to-date was positive SEK 105 million, but strip out projects and it was negative SEK 63 million. Occupancy has fallen to 87% from nearly 94% in 2022. The Q3 disclosure is unusually granular: about 30% of the portfolio saw leasing action this year, 10% of the stock terminated, renegotiated leases cut rents by 2.5%, like-for-like in-place rents fell 1.4%, rental income fell 1.7% and net operating income fell 3.6%. This is not a rounding error. The negative net leasing in standing assets is the hinge: projects can make the headline number look positive, but filling empty space in buildings already paid for is what drives recurring income. Pål Ahlsén is explicit:

The leasing market has not turned. “Still we are facing quite a lot of competition. It still have not turned around to a positive market.” — Pål Ahlsén, CEO · 2026-10-22 This is a recurring theme, not a fresh confession. In July the aim was simply “to work as hard as we can to get as many signed contracts as possible” — Pål Ahlsén, CEO · 2026-07-15, and in October 2025 management was already repeating “leasing, leasing, leasing” — Pal Ahlsen, CEO · 2025-10-23. The new information is not the problem itself; it is how long the problem has lasted.

Value changes tell the same story from the asset side. “Cap rate in our valuations has been very stable over the last couple of years. So the value declines that we have seen has been more of due to lower cash flow expectations.” — Christoffer Strömbäck, CFO · 2026-10-22 The value declines were broad across regions, with Gothenburg and Lindholmen a little worse. Average exit yield rose nine basis points, largely because the sold Alecta properties carried lower yield requirements than the group average. Castellum is selling its lower-yield assets and retaining a portfolio with more vacancy and more leasing risk. That may be the right portfolio choice, but it leaves the operating problem concentrated in what remains.

The buyback is rational; the balance sheet is the constraint

The financial logic is not reckless. Loan-to-value is 37.4% against a 40% policy ceiling; the interest coverage ratio is 3.1x against a minimum of three; the average interest rate is 3.5%; the average fixed-interest term is 2.7 years; and hedging was 61% at the report date, rising to roughly 75% after the Wihlborgs proceeds arrived. The company split disposal proceeds 40% to debt reduction and 60% to buybacks, keeping LTV roughly stable. Unutilised credit facilities were SEK 14 billion and have been restored since quarter-end. That is a defensible capital structure for a company with a wide NAV discount.

But the next domino is the hybrid. It is callable this winter, with the first call in December and the first reset next March. Management still will not decide in public. “We actually haven't made any decisions on that one.” — Christoffer Strömbäck, CFO · 2026-10-22 That is the same answer as three months ago: “The first call date is in December, and the first reset date is March next year. Something we are evaluating, and we'll come back with both how and when.” — Christoffer Strömbäck, CFO · 2026-07-15 The deferral is becoming a pattern. Analysts pressed on whether the buyback should take priority over deleveraging, especially because the hybrid is treated as 100% debt by S&P and pushes an adjusted LTV closer to 51%. The CFO acknowledged that all LTV measures are part of the discussion, but refused to lay out alternatives. For a company returning this much capital, the hybrid decision is the next real signal on capital allocation.

There is also a new cost consequence to the shrinking portfolio. Management is cutting admin cost by 15%, almost SEK 100 million, and reorganising from four regions to two. Roughly half the saving comes from staff and half from offices and smaller items, with the full balance-sheet effect arriving over about twelve months. This is the first tangible evidence that the smaller asset base is forcing a smaller central organisation.

Entra: the asset behind the curtain

The 37% stake in Entra is worth roughly SEK 11 billion, about a fifth of Castellum's SEK 58.7 billion market capitalisation. It has long been the elephant in the room. Pål now says the company should focus predominantly on Sweden, and that “our only concern now is to make Entra better or make Entra great again” — Pål Ahlsén, CEO · 2026-10-22. That is a subtle shift from February, when he said, “I really like Entra. Entra is a great company.” — Pal Ahlsen · 2026-02-18 The tone is no longer proud owner; it is value-fixer. If Entra becomes a funding source, the buyback capacity expands materially. But management says it is not discussing adding shares and that boardroom discussions must stay there. The transaction markets remain open, though higher long-term rates have made some buyers more reluctant; Castellum says its ongoing deals are proceeding as planned.

Bottom line

The global keyword tape confirms that profit from property management is a top-five theme this quarter, with Nordic peers such as Neobo and Logistea discussing the same metric. Castellum's version is decent at the per-share line — income from property management per share rose 4.7% year-to-date — but annualised return on equity is only 5.2% against a target above 10%. Buybacks are flattering NAV per share and EPS, but they are not fixing occupancy. The company is selling assets above fair value, returning most of the proceeds at a wide discount, and retaining a smaller, higher-vacancy Swedish portfolio plus an Entra stake. If leasing turns, the per-share math is powerful. If it does not, this is a shrinking company buying its own stock because it cannot find property investments with adequate returns. That is the tension.
