Yet the company offered no commentary "to allay investor concerns about discounting to make numbers and drive positive cash flow in the quarter," Osborne wrote. Musk last week urged employees to hew to pricing policies, responding to concerns that Tesla was straying from a long-held policy against discounting its cars.
Tesla on Sunday said its delivery count should be viewed as slightly conservative because it only counts a car if it's transferred to the customer and all paperwork is correct. The company reiterated that it expected to deliver 50,000 vehicles in the second half.
Tesla introduced a 60-kilowatt-hour Model S in June that starts at $66,000 before federal or state incentives. In August, the automaker added a 100-kwh battery option with additional range. The company also announced a two-year lease on orders placed by Sept. 12.
Tesla produced 25,185 vehicles, 37 percent more than in the second quarter.
Brad Erickson, a Pacific Crest Securities analyst with a neutral rating on Tesla, had estimated third-quarter deliveries at 22,000. In a Sept. 27 note, he said Tesla's U.S. sales centers were using a deeper discounting formula to boost third-quarter sales.
Tesla is increasing production at its Fremont, California, factory with an eye toward making 500,000 cars a year by 2018, a goal that also depends on the company's battery factory east of Reno, Nevada, coming online with battery-cell production. Both efforts will require more funding in the fourth quarter, Musk has said.
The third-quarter deliveries figure is a preliminary number that may change slightly in November when the company reports earnings for the period. The automaker releases global sales figures quarterly, instead of the monthly country-by-country results typically announced by other automakers.
