Costco Wholesale Corporation ($COST) is set to report its earnings for the second quarter of 2025 today, with market analysts expecting an implied stock movement of approximately +/- 4.5%. This follows recent negative reactions to earnings reports from competitors Walmart ($WMT) and Target ($TGT), raising concerns about Costco's performance. In light of ongoing tariff uncertainties, Costco executives have indicated that about one-third of their U.S. sales are derived from imported products, with less than half of those imports coming from China, Mexico, and Canada. The company has been actively purchasing additional inventory to prepare for potential tariff impacts. CEO remarks suggest that consumer caution may persist due to inflation and tariffs, stating, 'When it rains, it rains on everyone.' The earnings call will be broadcast live following the market's close today.
