EXPLANATORY NOTE

On June 24, 2026, the Istanbul 14^th Commercial Court of First Instance (the “Court of First Instance”) rendered its decision (Case No. 2024/768) regarding the unfair competition case brought by certain Turkish drivers’ and automobile trade associations against the ride-hailing business of Marti İleri Teknoloji A.Ş, a subsidiary of Marti Technologies, Inc. (the “Company”).

The Court partially granted the plaintiffs’ claims, holding that the Company’s ride-hailing service constitutes unfair competition under the Turkish Commercial Code. The Court rejected the plaintiffs’ request for an interim injunction to block access to the Company’s website and mobile applications, and rejected the plaintiffs’ claims relating to the Company’s e-scooter and e-moped services, finding that unfair competition had not been established with respect to those services. All of the Company’s services, including ride-hailing, two-wheeled electric vehicles, and delivery services, continue their operations uninterrupted.

The Company will appeal the Court of First Instance’s decision at the Istanbul Regional Court of Appeals within the statutory two-week period following receipt of the reasoned decision by the Court of First Instance. As of the date of this report, the reasoned decision has not been delivered to the Company.
