Chipotle Mexican Grill expects to increase prices again this year, but how much to compensate for higher wages in California remains the wild card. The burrito chain says on a 4Q call that it expects prices to be 2.5% to 3% higher in its current 1Q, but hasn’t decided on the rest of the year. Chipotle says around 15% of its restaurants are in California, where fast-food wages for chains will rise to at least $20 an hour in April.
