Tesla Motors, Inc. TSLA delivered 12,420 Model S and 2,400 Model X vehicles in the first quarter of 2016. This is significantly lower than its projection of 16,000 vehicle deliveries as well as 17,400 units delivered in the fourth quarter of 2015. However, the first-quarter 2016 deliveries represent a 50% improvement over the first quarter of 2015. Per Tesla, the lower-than-expected deliveries were a result of low production of Model X in the first two months due to parts shortage. However, production improved significantly to 750 Model X per week by the end of March. This will aid deliveries in the second quarter. As a result of the ramp-up in production by the end of the first quarter, Tesla reaffirmed its full-year delivery guidance of 80,000–90,000 units. Meanwhile, Tesla stated that there might be a marginal revision (less than 1%) in the first-quarter delivery figure as it counts a delivery only after the vehicle is handed over to the end customer and the paperwork is accurate. The company further clarified that its quarterly financial results do not depend solely on vehicle deliveries, but also on other factors such as cost of sales, foreign exchange movements and mix of directly leased vehicles. Tesla started reporting its quarterly vehicle delivery data from the first quarter of 2015 in order to dispel incorrect estimates usually made using erroneous information sources. The electric carmaker now reports its vehicle delivery volume within three days of every quarter end. Tesla currently carries a Zacks Rank #3 (Hold). Some better-ranked automobile stocks include Cooper Tire & Rubber Co. CTB, Visteon Corporation VC and The Goodyear Tire & Rubber Company GT. While Cooper Tire currently sports a Zacks Rank #1 (Strong Buy), both Goodyear and Visteon hold a Zacks Rank #2 (Buy). Want the latest recommendations from Zacks Investment Research?
