EXPLANATORY NOTE

On October 22, 2026, the 14^th Civil Chamber of the Istanbul Regional Court of Appeals (the “Regional Court”) ruled on the appeals filed against the June 24, 2026 decision of the Istanbul 14^th Commercial Court of First Instance in the unfair competition case brought by certain Turkish drivers’ and automobile trade associations against our ride-sharing platform, Marti TAG, which we have previously referred to as our ride-hailing service. The Regional Court accepted our appeal, set aside the first-instance decision and, ruling on the merits, dismissed the plaintiffs’ claims in both the main action and the consolidated action originally filed before the Antalya 1^st Commercial Court. The Regional Court also rejected the plaintiffs’ appeals, including their requests for interim measures to block access to our services. The decision was unanimous.

In its reasoned decision, the Regional Court held, among other things, that we do not act as a carrier nor directly provide transportation services, and that our platform operates as a hosting provider under Turkish Law No. 5651, and that, in the absence of legislation or administrative regulation prohibiting ride-sharing platforms or making them subject to a license or permit, such an activity cannot be prohibited by a court decision. The Regional Court concluded that our activities do not constitute unfair competition under the Turkish Commercial Code and that our advertising was not misleading.

The decision is not final. The plaintiffs may appeal the decision to the Turkish Court of Cassation within two weeks of service of the reasoned decision, and we expect that they will do so. If the Court of Cassation were to uphold the Regional Court’s decision, the case would be dismissed in its entirety; if it were to overturn the decision, the matter would be referred back to the Regional Court for further proceedings. We believe the Regional Court’s decision removes the basis for the enforcement proceedings previously initiated by the plaintiffs.

All of our services, including ride-sharing, two-wheeled electric vehicles and delivery services, continue to operate uninterrupted.
