SPIE, the independent European leader in multi-technical services in the areas of energy and communications, announces the acquisition of 96% of the shares in SD Fiber, a specialist in the deployment of fibre optic networks active in Switzerland and Germany.

Headquartered in Dietikon, in the Canton of Zurich, SD Fiber is a turnkey service provider for fibre roll-out, covering FTTS (fibre-to-the-street), FTTB (fibre-to-the-building) and FTTH (fibre-to-the-home). The company offers end-to-end solutions across the entire value chain, including planning, civil engineering, installation, commissioning, maintenance and troubleshooting. In addition, SD Fiber is active in smart metering and installs digital electricity meters, an important component for intelligent energy usage. In 2024, SD Fiber generated revenues of approximately EUR 70m and employs around 340 people across Switzerland and Germany.

With this acquisition, SPIE significantly strengthens its FTTX expertise in Switzerland and Southern Germany and broadens its service portfolio in an attractive and growing market. The company will also benefit from SD Fiber’s smart metering competence, a field with considerable growth potential. 

SPIE will hold 96% of the shares, while 4% will remain with SD Fiber’s management team, ensuring leadership continuity and commitment to further growth.
