Fast-food chain Sonic's stock shed more than 8 percent Wednesday after the company warned same-store sales could come in worse than expected.
Sonic said it expects comparable-store sales growth for the fiscal third-quarter to "be positive," but below its full-year target of 4 to 6 percent, citing "slower industry traffic and modestly unfavorable weather during the quarter."
The company is expected to report quarterly results on June 20.
Sonic shares are about flat over the past year, but have advanced more than 8 percent in the past six months.
