CP All Plc, the country’s largest convenience store chain, reported a 21% rise in quarterly profit, the highest growth among Thai retailers, as an increase in store openings helped offset weak domestic consumption.

In the previous quarter, sales rose 1.1% and fell 2.6% for the whole of 2014,Net profit was 3.26 billion baht for July-September, the company said on its website, in line with analyst forecast of 3.2 billion baht.The number of its 7-Eleven stores rose to 8,618 in the third quarter from 7,965 stores a year earlier. Customer numbers per store, however, were 1,230 per day, slightly less than 1,286 in the previous quarter, the company said.CP All also booked more revenue from cash-and-carry wholesaler unit Siam Makro Plc, which posted a 15% rise in quarterly net profit but same-store sales falling 0.7%. Another retailer Big C Supercenter Plc posted a 5.2% decline in same store sales due to weak consumption. CP All, which aims to open 600 stores this year, is on track to have 10,000 branches by 2018.
