Wal-Mart Stores (WMT) topped the Fortune 500 for the 4th year in a row despite clocking in its first decline in total sales ever, as the strong U.S. dollar hurt sales overseas. Still, Wal-Mart Stores is looking to reinvent itself by becoming an e-commerce power house and re-inventing its grocery business.
The retail giant has given hundreds of thousands of workers raises, resulting in improving customer service scores, built a mobile payment app of its own and is doubling down on organic and fresh food to stand out in the crowded retail industry. Comparable U.S. sales rose each quarter, while more shoppers came to its domestic stores in 2015, but executives readily admit there is still a lot of work to do.
