More than half of what the home improvement retailer sells comes from the U.S., CFO Richard McPhail told CNBC.

Home Depot stuck by its full-year guidance, even though it missed Wall Street's first-quarter earnings estimates. CFO Richard McPhail said the home improvement retailer has diversified where it sources its merchandise and won't raise prices because of higher tariffs.

The maintained forecast comes during a period when numerous corporations have either revised or withdrawn financial guidance due to rapidly changing tariff policies from the current presidential administration. Home Depot’s willingness to maintain its outlook suggests confidence in its ability to navigate these uncertain trade conditions.
