(RTTNews) - Retail giant Walmart Inc. (WMT) reported Tuesday a loss for the third quarter compared to a profit last year, despite strong revenue growth, hurt by hefty $3.3 billion charges related to opioid legal settlements. Consolidated gross profit rate decreased 89 basis points, primarily due to markdowns and mix of sales in the U.S., an inflation-related LIFO charge at Sam's Club, and the timing of Flipkart's annual event, The Big Billion Days. Consolidated operating expenses as a percentage of net sales increased 144 basis points, due to charges of $3.3 billion related to opioid legal settlements.
