The news check keeps the assessment current.
General analysis — not personal advice.
Maintain the position; consider adding gradually if (1) buybacks continue at a strong pace and (2) H1/Q2 shows stabilization in like-for-like rents/NOI and major disposals (AP7) close as planned.
Large buybacks and cost reductions support shareholder value while like-for-like rental income and occupancy continue to face pressure.
The market reacts positively to the large buyback programme and capital return despite continued weak operational performance.
HOLD is the call. Positive is the market mood. Medium risk means some things can go wrong.

Castellum AB (publ) is a Nordic real estate company owning, developing, and managing commercial properties (offices, logistics/warehousing, and public-sector properties). The company has stable rental income and property management earnings but has been impacted by property value write-downs and pressured net leasing. Management is focused on capital allocation, divestments, and share buybacks.
Bull case
Aggressive buyback programme funded by property sales provides support for NAV per share.
Bear case
Negative net leasing and falling like-for-like rental income highlight continued weak demand in the office market.
Why this signal
Large buybacks and cost reductions support shareholder value while like-for-like rental income and occupancy continue to face pressure.
