Half a year after Chipotle first suspended a key pork supplier for not meeting its animal welfare standards, about 40 percent of its locations still do not carry carnitas, and that's a problem for the chain.
On Tuesday, the restaurant reported comparable restaurant sales growth of 4.3 percent. For many other restaurant chains, this would have been a blockbuster quarter. But at Chipotle, investors have grown accustomed to high figures—helped in part by a price increase last year—and the number missed forecasts.
Partly to blame was the lack of carnitas at a large number of locations.
"We still think we're being hampered by not having carnitas, and we think that could be as much as a couple hundred basis points" off same-store sales growth, said Chipotle CFO Jack Hartung on the company's conference call. To put that in perspective, 200 basis points equals 2 percent.
