Chipotle shares are falling in early trading after the company reported disappointing sales on Tuesday.
The stock fell by more than 5% early Wednesday to as low as $650.05 per share.
Year-to-date, shares are down 4%.
In the first quarter, same-store sales rose 10.4%, missing expectations for growth of 11.8%.
Earnings per share came in at $3.88 on revenue of $1.09 billion; analysts were expecting EPS of $3.65 on revenue of $1.1 billion.
Chipotle CEO Steve Ells said that because the company cannot find enough pork suppliers that meet its standards, there will continue to be a shortfall.
If everything goes to plan, carnitas will be back in full supply by the fourth quarter, he said.
