What Rejlers does

Rejlers AB (publ) is a Nordic engineering consultancy founded in 1942 in Stockholm, listed on Nasdaq Stockholm Mid Cap (ticker: REJLR) since 2003, and headquartered in Stockholm with regional headquarters in Helsinki, Oslo, and Abu Dhabi. The firm employs approximately 3,600 people and operates across Sweden, Finland, Norway, and the UAE, organised around three horizontal service lines: Energy Transition (renewables, grid modernisation, electrification, energy storage), Industry Transformation (automation, decarbonisation, digital/industrial IoT), and Future-proof Communities (transportation, water, buildings, urban infrastructure). Its in-house Sustainalyzer tool provides a proprietary sustainability assessment capability that anchors the firm's sustainability-led value proposition.

Rejlers generates revenue almost exclusively through professional-services engagements, delivered as time-and-materials or fixed-price mandates, typically structured as multi-year framework agreements with enterprise and public-sector clients. Go-to-market is enterprise field sales into infrastructure owners, energy TSOs/DSOs, telecoms, industrial operators, data-centre developers, and municipalities; disclosed client logos include Vattenfall, Ellevio, Fingrid Oyj, Svenska kraftnät, Telia Towers Finland, Skanska, atNorth, St1, Mölnlycke Healthcare, Elenia Oy, the Swedish Transport Administration, and Huddinge Samhällsfastigheter. Marketing is anchored on thought-leadership content, LinkedIn (77,000+ followers), the Rejlers Play YouTube channel, and the annual report.

The business model is people-hours-led with limited proprietary software monetisation. Growth has been a combination of organic expansion and an aggressive Nordic bolt-on M&A programme — most recently Rörkraft AS, SGM Consulting, and Future Technology AS during 2026, following Karl Knudsen (2023), Three Kings (2023), Omega Holtan (2022), and Solvina (2024). FY2025 net sales were SEK 4,741.0M with record EBITA of SEK 377.7M, and the company holds top-tier sustainability credentials including EcoVadis Platinum (top 1%, score 84/100), SBTi-validated targets, and ISO 9001/14001/27001/45001 certifications.
