Singapore supermarket operator Sheng Siong boosted its net profit by 7.4 per cent in the June quarter, to S$18.42 million. 

Sales rose 11.8 per cent to $238.16 million on the back of 13 new store openings. 

However the company has warned investors that competition in the Singapore supermarket sector is tough, from both online retailers and rival supermarket chains. Worse, consumer spending may be impacted by a soft economic outlook. 

In the half year to date, Sheng Siong recorded a 6.6 per cent increase in net profit to $37.78 million, on sales up 11 per cent to $489.59 million.
