After years of intensive investment in fiber-optic infrastructure, DELTA Fiber is entering a new phase in which continued customer growth and network utilization take center stage. DELTA Fiber’s 2025 annual report shows that the company continues to expand.
Revenue increased to EUR 456* million in 2025, with EBITDA reaching EUR 259 million. At the same time, investment levels are declining as the rollout phase nears completion, shifting the company’s focus from investment toward returns and cash flow generation.
Over the past several years, DELTA Fiber has invested approximately EUR 2 billion in a nationwide fiber-optic network. That network now reaches approximately 1.7 million households and businesses and serves more than 640,000 customers. The company aims to grow to one million active customers by 2030.
As a result, the strategy is shifting from building to maximizing utilization. The combination of a strong retail brand and a growing wholesale ecosystem is contributing to higher network utilization. The open-network model plays a key role in this strategy: more than twenty service providers now deliver services via DELTA Fiber’s network, with VodafoneZiggo joining as the newest partner.
Telecommunications infrastructure is increasingly viewed in financial markets as a so-called “HALO asset” (Hard Asset, Low Obsolescence). This refers to future-proof physical infrastructure with a long lifespan that continues to increase in value due to technological developments such as AI.
Marco Visser, CEO of DELTA Fiber, commented: “In an economy that is becoming more dependent than ever on digitalization, partly driven by the rise of AI, our fiber-optic network provides a stable and valuable foundation. Demand for higher bandwidth and reliable connectivity continues to grow. At the same time, we are actively using AI to further automate our processes, manage the network more efficiently, and serve our customers even better.”
Looking ahead, the company expects that the combination of continued customer growth, declining investment levels, and increasing network utilization will translate into positive monthly cash flows by the end of 2026.
