Tesla said Monday that it had delivered 14,820 vehicles in the first quarter — shy of guided expectations of 16,000 deliveries because of a parts shortage.
The electric automaker said that one of the root causes of its production-hampering parts shortage was "Tesla's hubris in adding far too much new tech to the Model X." Still, the company reaffirmed its full-year delivery guidance of 80,000 to 90,000 vehicles.
Tesla shares fell in after-hours trading following news of the deliveries miss.
For the first quarter, the company said it delivered 12,420 Model S and 2,400 Model X vehicles.
In February, Tesla delivered a fourth quarter loss worse than analysts had expected, but its stock still rose on strong deliveries guidance for 2016.
