Transport giant ComfortDelGro Corp will have to contend with thinner margins, higher debts, more mergers and acquisitions, and new businesses if it wants to continue growing, according to its long-serving chairman Lim Jit Poh.

Speaking to The Straits Times as the group - the result of a merger between Comfort Group and DelGro Corp - turned 15 last week, Mr Lim said: "We are fully aware that the playing field has changed. Technological advances are going to change the make-up of the very vehicles we rely on as a mainstay of our business."
