What Transtema does
Transtema Group AB (publ) is a Mölndal, Sweden-based critical-communications infrastructure services company founded in 1997 and listed on Nasdaq Stockholm Main Market (ticker: TRANS) since 2021. The company designs, installs, services, maintains, and monitors fiber networks, mobile (including 5G) networks, network operations, data centers, power grids, battery energy storage systems, and EV charging infrastructure for Nordic telecom operators, energy companies, municipalities, and property owners. Transtema employs approximately 1,300 people across Sweden and Norway and operates a 700-vehicle field-service fleet providing 100% geographic coverage in Sweden, backed by a 24/7 monitoring center.
The company's revenue model is built on project-based contracts and long-term service agreements (3-15 years) with enterprise customers such as Telenor, Telia (including Telia Towers, ~150 MSEK), GlobalConnect, E.ON, Tibber, Proptivity, Trafikverket, and STOKAB. Services are sold via direct enterprise sales teams and delivered through a wholly-owned subsidiary structure (Transtema Network Services, Transtema AB, Transtema Mobile, Transtema Datelab, Transtema Foki, Transtema Charge, Transtema Service & Underhåll, and Transtema Norge). The company's history is one of aggressive inorganic growth: more than 15 disclosed acquisitions since 2016, including the 2018 Ericsson LSS acquisition that doubled revenue, plus a 2022 expansion into EV charging (North Projects) and Norwegian telecom (Tessta Connect, UBConnect).
FY2025 reported net turnover was 2,600 MSEK (up 4.5% YoY), but the period was marked by a 19.6% Norwegian revenue decline, a 120 MSEK non-cash impairment of Norwegian goodwill and customer relationships, a Q4 2025 adjusted EBITA margin of just 0.3%, the abrupt January 2026 departure of CEO Henning Sveder (replaced by acting CEO Jonas Rigner), a cost-saving program affecting approximately 250 positions, and a May 2026 fully guaranteed 40.3 MSEK rights issue to stabilize the financial position.

Company assessmentRegional players
- NRC Group: Nordic infrastructure services company focused on rail and environmental construction with adjacent telecom/energy capabilities. Adjacent comparable for Nordic field-services execution model though primarily rail-focused.
- Infranord: Swedish state-owned rail and infrastructure services provider. Comparable Nordic field-services operating model with similar workforce scale and public-sector contracting approach, though primarily rail-focused.
Broad incumbents
- Caverion: Nordic technical building and infrastructure solutions provider with telecom and power service capabilities. Operates at significantly larger scale than Transtema across the Nordics and Baltics, providing a relevant scaled comparable for the field-services model.
- Bravida: Large Nordic technical installation and service company covering electrical, telecom, and energy infrastructure across Sweden, Norway, and other markets. Broader portfolio than Transtema but competes directly on telecom and power installation contracts.
Emerging players
