Summary

  • France’s competition authority has temporarily paused Orange’s new fibre rollout and wholesale canvassing in parts of Mayotte while it examines a dispute over a territory-wide public-service concession.
  • The case turns on more than duplicate cables: the authority says a build in five of 17 municipalities could unsettle the revenue and subsidy structure meant to support coverage in less-profitable areas. Its view is provisional, not a final finding of abuse.

Analysis

The order does not ask whether Mayotte needs fibre. The island’s copper network was damaged by Cyclone Chido, and the public-service plan and Orange’s project both propose a route away from that legacy network. The question is who gets to shape the new map, and what happens to the economics when two plans overlap before the public one has secured its funding.

The Département-Région de Mayotte signed a public-service delegation in January 2025 with Réunicable for fibre across all 17 municipalities. Réunicable assigned delivery to its subsidiary Mayotte THD. Orange had also bid in the tender. In March 2025, it began a separately financed rollout in five municipalities, with an announced objective of connecting 27,771 premises by 2030.

Those five places matter because density changes the cash flow of a network. The Autorité de la concurrence describes them as among Mayotte’s denser and more profitable municipalities. The same account says the public concession’s revenue model depends on balancing the territory, including areas where expected returns alone are not enough to fund construction. That is the economic hinge: a private build can add capacity and choice in the locations it serves, yet still alter the revenue base against which a wider coverage commitment was financed.

The authority says the coexistence of the two projects created a risk of duplicate deployment. The national public-funding agency suspended assessment of the public network’s subsidy application; the Authority says the state’s funding commitment was consequently put on hold. This does not prove that the subsidy would otherwise have been approved, or that Orange’s build alone caused every financing problem. It shows that the overlap became consequential before a final competition ruling: project finance and the scope of an interim order moved while the merits remained open.

On 21 October, the Authority ordered Orange to suspend further rollout and wholesale-market canvassing in areas not yet built. It also required a status report on existing fibre and the copper and civil-engineering infrastructure, and access to Orange-controlled ducts when the concessionaire needs them for the public project. The order can be revised if the public network is abnormally delayed, the parties agree to co-rollout across Mayotte, or the concession is adjusted to incorporate existing Orange construction, with funding terms changed where appropriate.

That reversibility matters. This is not a permanent ban on private investment, an order to dismantle completed fibre, or a final conclusion that Orange abused dominance. The Authority says only that the conduct is likely to constitute an abuse and risks serious, immediate harm at this stage. The full decision was not yet posted when this report was prepared.

The wider lesson is narrower than “overbuild is bad.” In a public-initiative network, the boundary between commercially attractive and publicly supported areas is part of the financing design. A parallel network can improve service where it is built; if it captures the locations carrying the concession’s expected revenue while public money is pending, it can also change the conditions under which the less-dense remainder gets built. The relevant test is not just how many premises each plan can reach.

It is whether the rollout, wholesale access, civil-engineering rights and funding timetable fit together well enough to preserve the territory-wide obligation.
