Chipotle Mexican Grill's giveaways may have gained some traction ahead of the embattled chain's earnings Tuesday.
The restaurant, which had its earnings and stock price battered by an E. coli outbreak, has turned to freebies this year to bring back customers. Company watchers have been split on how much the promotions will help Chipotle recover.
Chipotle's shares have dropped more than 30 percent in the last year in the wake of food safety concerns. Last month, the restaurant said it expects a loss of $1 per share or more in the first quarter, driven by higher costs for food safety, legal and marketing efforts.
As Chipotle gets set to report Tuesday, one firm feels the promotions may be helping.
