In July 2014, Grupo TMM contributed $40,000 to the capital stock of Almacenes de Jugos Citricos de Mexico, S.A.P.I. de C.V., which represents 21% of the voting shares. Since this entity has not started up operations as of the issue date of the consolidated financial statements, Company’s Management decided to reserve the investment in its entirety.
 

 (b)
The Company lost control of its Marítima del Golfo de México y Subsidiarias para el Petróleo, S.A. de C.V. (Marítima del Golfo) before TMM División Marítima, S.A. de C.V. in 2017, retaining 15% equity in its capital without exerting significant influence. Accordingly, this investment has been classified as an investment in associate. As of December 31, 2024, and 2023, the value of this investment is nil, since the stockholders’ equity of Marítima del Golfo is negative. Moreover, in accordance with the statutes of Marítima del Golfo, the stockholders only assume obligation in connection with their equity up to the amount thereof.
