US retail giant Walmart has reported that it achieved 'solid' net sales growth during the September period of 5.8 per cent, hitting US$36.2bn, up from US$34.2bn during the previous year.

The results were achieved despite the impact of hurricanes Gustav, Hanna and Ike, which forced the temporary closure of 341 stores in coastal areas of the US during the period.

Same-store sales jumped 2.4 per cent during the five-week period, the group said, driven by fresh food sales at both Walmart and Sam's Club stores.

'In spite of both the impact from the hurricanes and the recent challenges to consumer confidence as a result of the economic environment, Walmart US had another period of comparable store sales performance,' said Eduardo Castro-Wright, president and CEO of Walmart US. 'We continue to believe that the strong Walmart value proposition is bringing more and more customers to our stores.'
