AUCTUS has sold SD Fiber to SPIE
SD Fiber
SD Fiber, founded in 2012 and headquartered in Dietikon, Switzerland, is a specialist in fiber optic network deployment across Switzerland and southern Germany. The company offers turnkey solutions covering the entire value chain—from planning, civil engineering and installation to commissioning, maintenance and troubleshooting. The company has also expanded into complementary verticals such as smart metering, broadening its capabilities while deepening customer value.
The Deal
SD Fiber has experienced remarkable growth in recent years through its partnership with AUCTUS Capital Partners, driven by robust digitalized processes, a strong focus on operational excellence and a relentless commitment to quality. The strategic backing enabled the company to grow organically to over 300 employees while maintaining its reputation for high-quality service delivery. To support the next phase of its development, Lincoln International conducted a broad process to identify a strategic partner aligned with SD Fiber’s long-term vision. The resulting partnership with SPIE will allow SD Fiber to retain its existing management team, who will continue to lead the company and will contribute to its ongoing business development. The acquisition supports SPIE’s strategic objective of becoming a leading provider of FTTx infrastructure services in Switzerland, while also strengthening its position in the German market.
Christoph Stockbrügger, Director of AUCTUS Capital Partners, commented: “We are delighted about the successful sale of SD Fiber to SPIE, and we thank Lincoln’s team for their highly professional support and tireless commitment to ensure a smooth process and a great outcome for all stakeholders.”
