The Grupo TMM, S.A.B.

We expect to record a net income of Ps. 1,329.6 in 2017, compared to a net loss of Ps. 506.6 million in 2016.  We expect that the change in net income in 2017 is primarily due to an expected increase in other income to Ps. 3,217.7 million in 2017 compared to Ps. 52.9 million in 2016.  The expected increase in other income in 2017 is primarily attributable to an expected gain of Ps. 3,458.5 million on the loss of control of a subsidiary, TMM Division Maritima, S.A. de C.V.
