Kraft Heinz lowered its full-year sales and earnings guidance Tuesday, citing weaker customer spending in the U.S. and the impact of President Donald Trump’s tariffs. It’s the latest big food company to issue disappointing results. Last week, PepsiCo lowered its full-year earnings forecast, also citing tariffs. Kraft Heinz acknowledged that it’s in a tough spot. It needs to keep prices low to prevent consumers from migrating to cheaper store brands of products like ketchup. But tariffs will add to its expenses. The company said it’s looking for alternative suppliers and may reformulate some products to try to mitigate tariff costs.
