On November 28, 2025, Pheton Holdings Ltd, a Cayman Islands company
(the “Company”) terminated engagement of Marcum Asia CPAs LLP (“Marcum”) as the Company’s
independent registered public accounting firm. The change was approved by the audit committee of the board of directors of the Company.
The Company’s decision to terminate the engagement was not the result of any disagreement between the Company and Marcum on any
matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure.

The principal accountant’s report of Marcum on the financial
statements of the Company as of and for the fiscal years ended December 31, 2024, 2023 and 2022 did not contain any adverse opinion or
disclaimer of opinion and was not qualified or modified as to uncertainty, audit scope or accounting principles. Marcum was engaged since
September 30, 2022.

During the fiscal years ended December 31, 2024, 2023 and 2022 and
the subsequent interim period through November 25, 2025, the date of termination of the engagement, (i) there were no “disagreements”
(as described in Item 16F(a)(1)(iv) of Form 20-F and the related instructions) between
the Company and Marcum on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures,
which disagreements, if not resolved to Marcum’s satisfaction, would have caused Marcum to make reference to the subject matter
of the disagreement(s) in connection with its report to the subject matter
