Chipotle Mexican Grill is considering increasing prices after 2019 costs are predicted to rise by about $15 million because of tariffs proposed last week by President Trump.

“If the tariffs become permanent, we would look to offset these costs through other margin improvement efforts already underway,” Chipotle CFO Jack Hartung said in a Monday statement to Bloomberg. “We could also consider passing on these costs through a modest price increase, such as about a nickel on a burrito, which would cover the increased cost without impacting our strong value proposition.”
