About DELTA Fiber

DELTA Fiber owns and operates the second-largest fiber network in the Netherlands, passing around 1.7 million homes and businesses in rural and suburban areas. EQT Infrastructure III formed the company by combining DELTA, a long-standing provider in the province of Zeeland, with CAIW. Through the DELTA brand, the company offers high-speed internet, TV, fixed telephony and mobile services to consumers and businesses. In addition, DELTA Fiber offers wholesale access to its network to other internet providers. In 2026, DELTA Fiber directly and indirectly serves more than 650,000 customers.

Market trends and drivers

Demand for high-speed, reliable connectivity in the Netherlands continues to grow, as households and businesses increasingly rely on data-intensive services such as video streaming, remote working and cloud applications. Fiber is widely regarded as the most future-proof technology to meet this demand, while the gradual phase-out of legacy copper networks is further accelerating the shift to fiber. At the same time, the Dutch market is moving towards open-access models, in which multiple service providers deliver their offerings over shared infrastructure, especially in less densely populated areas of the country. This approach increases utilization of existing networks, strengthens competition and consumer choice, and favors owners of high-quality fiber platforms such as DELTA Fiber.

Investment potential

Supported by a strong industrial board with local, national and international expertise in fiber and the broader telecom sector, DELTA Fiber's experienced management team aims to develop the company into an operationally and commercially best-in-class fiber platform. The company's unique pan-regional fiber network is attractive to both retail customers and wholesale partners, and it operates in a Dutch broadband market with strong structural growth and an increasing focus on service quality. Its well-established brands and long-standing customer relationships, combined with a future-proof, fully invested core network and strong regional presence, create high barriers to entry. With EQT's support, DELTA Fiber will continue to expand its network, open it to additional wholesale partners and capture the growth potential from connecting more households and businesses.
