What Kungsleden does
Castellum, which absorbed Kungsleden, is one of the largest listed commercial property companies in the Nordic region, owning, managing, and developing office, logistics, retail, and public-sector properties in growth cities across Sweden, Denmark, and Finland, with additional Norwegian exposure through its ~34% stake in Entra ASA. As of March 2026 the portfolio comprised 669 properties, 5.3 million square metres of lettable area, and a property value of SEK 138 billion, with 7,400 commercial leases and 450 residential contracts in place. Castellum is listed on Nasdaq Stockholm Large Cap under the ticker CAST and has roughly 99,000 shareholders, a Moody's Baa2 rating, and a Nordic capital base supporting a SEK 138 Bn asset base.
The company operates three integrated service lines: Property Management, providing decentralised customer-centric management organised around six geographic regions (Stockholm, West/Gothenburg, Central, Mälardalen, Öresund, and Finland); Project Development, covering continual investment in existing assets and new developments such as Hagastaden in Stockholm and GreenHaus in Helsingborg (50+ ongoing projects); and Transactions, which manages portfolio rotation via acquisitions and divestments, including the June 2026 SEK 5.0 Bn Stockholm office sale to Alecta Fastigheter. Core technology is a physical and sustainability infrastructure platform rather than software: 130 solar PV systems (23 MW), 1,627 EV charging stations, 1,282 green leases, and certifications including Miljöbyggnad (Gold offices, Silver logistics), NollCO2, WELL Portfolio (covering nearly 18,000 tenant employees), DJSI membership, and Nasdaq Green Equity Designation.
Revenue is generated primarily through recurring rental income on long-term commercial leases billed monthly, with Q1 2026 income of SEK 2,321M and income from property management of SEK 1,079M (annualised roughly SEK 9.3 Bn). Customer segments are split between private commercial enterprises (office, logistics, retail) and public-sector tenants, served via country-specific websites (castellum.se, .dk, .fi), direct regional sales teams, and an investor-relations-driven B2B marketing approach. Castellum is led by CEO Pål Ahlsén and CFO Christoffer Strömbäck, with Filip Elland as Chief Sustainability Officer, and is pursuing a net-zero greenhouse gas target by 2040, having already reduced Scope 1 and 2 emissions by 83% since 2007.
