Wal-Mart reclaimed the top spot in the Fortune 500 in 2012 after slipping to No. 2 last year. The retailer’s refocus on low prices continued to attract frugal shoppers into the discounter's U.S. stores.
For fiscal year 2012, sales rose 5.9%, to $443.9 billion. Despite relatively strong sales, Wal-Mart must hold onto its U.S. shoppers, which make up 62% of the chain’s net sales.
Beyond the U.S., Wal-Mart continues to investigate allegations that executives in Mexico paid more than $24 million in bribes to speed the retailer’s expansion there. The probe has widened to Brazil, India and China.
