The fast-food chain's stock dropped to its lowest value in nearly two months Wednesday after Krebs on Security reported that a breach in the company's payment systems may have led to a "fire sale" of millions of stolen credit and debit card accounts.
As of Wednesday morning, shares fell at least 4.4% to $23.52, the biggest drop within one day since Aug. 8, Bloomberg reports.
“We are working to understand the nature and scope of this issue, as we know how important this is to our guests,” Sonic said in a statement, acknowledging that its credit card processor informed them about the breach last week.
Chipotle in May reveled that hackers installed software within its point-of-sale devices to gain access to customer data.
