Tesla Inc. shares plummeted as a record decline in deliveries during the first quarter stoked concern of slackening demand for the Model 3 sedan that started selling less than two years ago.
The electric-car maker delivered 63,000 vehicles in the three months that ended in March, down from 90,966 in the fourth quarter. Tesla shares sank as much as 11 percent to $260.59 as of 9:30 a.m. Thursday in New York.
