EXPLANATORY NOTE

On June 5, 2026, Marti Technologies, Inc. (the “Company”) entered into Amendment No. 2 (“Amendment No. 2”) to the Note Subscription Agreement, dated April 16, 2025, as amended by Amendment No. 1 on October 31, 2025 (the “Note Subscription Agreement”), by and among the Company, Callaway Capital Management, LLC, and the subscribers party thereto.

Pursuant to Amendment No. 2, the parties amended, among other things, the definition of “Reset Conversion Rate” applicable to the Company’s 12.50% Convertible Senior Secured Notes due 2029. Specifically, the multiplier used in the calculation of the Reset Conversion Rate was reduced from 1.65 to 1.05. The reduction of the multiplier has the effect of lowering the effective conversion price applicable upon a reset event.

As of the date of the amendment, $13.0 million principal amount of notes had been drawn, with $10.0 million remaining available for future drawdowns. The amended Reset Conversion Rate applies to all notes outstanding and issuable under the Note Subscription Agreement, including the $13.0 million principal amount drawn to date and any notes that may be issued pursuant to future drawdowns of the remaining $10.0 million amount.

The foregoing description of Amendment No. 2 does not purport to be complete and is qualified in its entirety by reference to the full text of Amendment No. 2, which is attached hereto as Exhibit 10.1 and incorporated herein by reference.
