PepsiCo plans to raise prices on select single-serve snack bags in the United States beginning in late June, with increases amounting to roughly 10 to 20 cents per bag. The company said pack sizes and product quality will remain unchanged.

PepsiCo, the company behind brands including Pepsi, Lay's, Doritos, Gatorade and Quaker Oats, is implementing the changes due to longer-running cost pressures across its business rather than disruptions caused by the Iran war. A PepsiCo Foods U.S. spokesperson said the company "held the line" on its smallest chip bags for nearly 15 years.

"Most will still ring up under $3 and many under $2," the spokesperson said. "Our commitment to affordability hasn't changed."

Earlier this year, PepsiCo lowered prices on many larger take-home snack bags by up to 15% in an effort to boost demand from cost-conscious consumers and families. Those price reductions helped drive nearly 9% revenue growth in the company's latest quarter.

On the company's earnings call last month, Chief Financial Officer Stephen Schmitt said PepsiCo was "investing in value." Chief Executive Officer Ramon Laguarta said that lower prices on larger take-home snack bags sold in grocery stores were helping bring shoppers back into the category.

Rising energy prices stemming from the Iran war continue to increase transportation, grocery and household costs, with many consumers experiencing financial strain. Inflation was running at 3.8% in April, above the 3.6% pace of wage growth that month.
