Castellum AB (publ) (CWQXY) Q2 2026 Earnings Call Transcript

Castellum reported Q2 2026 asset sales at strong prices, selling its Öresund region portfolio (ex-Copenhagen) to Wihlborgs for SEK 13.3B and a Stockholm portfolio (2 buildings) to Alecta for SEK 5.0B. The company also continued capital returns via buybacks, purchasing 39M shares for SEK 4.6B in the first six months of 2026. On leasing, Ericsson is taking the full Infinity space and Castellum signed leases for two additional Hagastaden buildings, though these are subject to conditions and likely won’t impact net leasing until late 2027.

Analysis

The near-term winner is CWQXY itself: monetizing non-core assets at what management views as attractive pricing turns a valuation debate into a capital-allocation story, with buybacks likely to be more accretive than reinvesting into a market where office yields are still uneven. Second-order, the better comp may be Wihlborgs and other Nordic core-office owners: if they are paying these levels, it supports a firmer floor for prime Stockholm/Öresund assets and can help NAV confidence across the sector.

The catch is that this is more defensive than growth-enhancing. If management keeps recycling assets into repurchases, equity value becomes increasingly dependent on discount-to-NAV math and less on NOI expansion, which can cap multiple expansion once the market stops rewarding "shrinking done well." Ericsson staying in place helps sentiment, but the delayed conditions on the incremental leases mean the earnings lift is probably a 2027 story, not a Q3/Q4 catalyst.

I’d treat this as a 1-3 month sentiment trade, not a multi-year compounding thesis, unless leasing momentum broadens beyond one anchor tenant. The bullish case is falsified if future disposals come at weaker pricing, buyback pace slows, or leverage relief is offset by softer occupancy/guidance; the bearish case is reversed if Castellum converts the remaining portfolio into more accretive capital returns without sacrificing rent roll quality. Consensus may be underestimating how much optionality these disposals create for buybacks, but also overestimating the durability of a rerating when the asset base is being thinned rather than upgraded.

Key Decisions for Investors

• Buy CWQXY on pullbacks over the next 2-4 weeks; target a short-dated rerating as the market prices in capital return discipline, with the trade thesis invalidated if management signals buybacks will pause or disposal pricing weakens.
• Pair long CWQXY vs short a higher-leverage Nordic commercial-property proxy over 1-3 months to express balance-sheet de-risking vs refinancing risk; close if credit spreads compress meaningfully or office cap rates re-expand downward.
• Set a watch item on the 2027-dated leasing conditions tied to the new Ericsson space: if those agreements slip further, the incremental earnings contribution is delayed and the stock should be faded into strength.
• Take profits on any sharp post-print rally if the stock moves to a meaningful premium versus implied NAV, since the upside then depends on further accretive asset sales rather than organic growth.
