On July 23, 2026, the Belgian Competition Authority (BCA) announced the closure of its investigation into the proposed cooperation between Proximus/Fiberklaar and Telenet/Wyre for the rollout of fiber networks in suburban Flanders. This cooperation aims to share fiber network rollout efforts while maintaining separate operations in urban centers.

The BCA's investigation, initiated on July 26, 2024, was prompted by concerns that the cooperation could significantly reduce competition in network infrastructure across Flanders, potentially affecting telecommunications service supply. The BCA, in collaboration with the Belgian Institute for Postal Services and Telecommunications (BIPT), worked to ensure that the benefits of the cooperation would be fairly shared among network users.

As part of the agreement, Proximus/Fiberklaar and Telenet/Wyre committed to several obligations, including expanding fiber coverage to over two million living units in suburban Flanders and providing open access to their networks at fair and reasonable terms. This includes a 30% reduction in basic wholesale access rates and improved access conditions for various network users.

The BCA's decision reflects a balance between enabling infrastructure development and addressing competition concerns. The commitments made by the parties are set to remain in force for over 25 years, with compliance monitored by the BIPT. The BCA emphasized the importance of this decision for Belgium's economic development and the role of public authorities in facilitating fair competition.
