General analysis — not personal advice.
HOLD
7/10
Confidence
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.
Hold: capital allocation has become more shareholder-friendly (large buyback program + share cancellation) and may narrow the NAV discount, but like-for-like operating metrics remain under pressure; the next key datapoint is H1/Q2 and execution of the AP7 disposal during Q2–Q3.
Market sentiment
9/10
↑
Trend: Improving
Sentiment has strengthened further as the SEK 3.0bn buyback decision and above-consensus reporting provide clearer support for NAV/EPS per share, even though like-for-like rental/NOI trends remain negative.
Risk assessment
6/10
Dilution:
Low
Buybacks ongoing; no planned equity raise.
Jurisdiction:
Low
Operations in stable Nordic countries.
Execution:
Medium
Leasing and valuations must improve.

Horizon:
Bull case
Share buybacks may provide technical support and signal a NAV discount.
- The Q1 report could show stabilization in net leasing/valuation changes.
- Continued property divestments can strengthen the balance sheet.
Bear case
Risk of further write-downs if yields/rents remain under pressure.
- Interest expense may continue to weigh on earnings.
- Weak office markets may drive negative net leasing.
Signal rationale (informational)
Hold: capital allocation has become more shareholder-friendly (large buyback program + share cancellation) and may narrow the NAV discount, but like-for-like operating metrics remain under pressure; the next key datapoint is H1/Q2 and execution of the AP7 disposal during Q2–Q3.
Recent news
- The H1 2026 report shows large divestments of about SEK 24bn, weaker like-for-like rental income (-2.0% excl. FX) and NOI (-4.8%), but Q2 came in above consensus on several key lines. The board decided to initiate share buybacks of up to SEK 3.0bn (60% of proceeds from the Alecta transaction) and the company continues to emphasize capital allocation via divestments and buybacks. New leasing announcements were communicated (incl. Ericsson in Hagastaden and the Swedish Prison and Probation Service in Linköping).
