Pos Malaysia, in a statement, said the company is now searching for a suitable replacement.
Syed Md Najib was appointed to his post in October 2018, when there was a structural decline in mail volume and a major shift in consumer behaviour towards what Pos Malaysia termed as "digitally abled platforms".
He is the fifth CEO appointed by the group since the departure of Datuk Seri Syed Faisal Syed Ali Rethza Albar, who relinquished the group managing director cum CEO post in January 2012. Incidentally, Syed Faisal, who is group managing director of DRB-Hicom Bhd, is now Pos Malaysia's non-executive chairman following the resignation of Yasmin Mahmood from the post on April 1 after a two-year term.
