Model 3 production woes continue for Tesla, albeit with modest signs of progress.

Tesla has announced its fourth quarter (Q4) numbers, citing 29,870 delivered vehicles. Of those, 50 percent were Model S sedans, 42 percent were Model X crossovers, and a paltry 5 percent, or 1,500 cars, were Model 3s.

Although these numbers constitute a 7-percent increase in production over the previous quarter, the market expressed its discontent, resulting in a 10-percent drop of Tesla’s stock to approximately $317, with continued downward movement after hours, slightly dropping its market value to $53 billion.

In a statement, Tesla expanded on its progress, citing reduced production bottlenecks and a commitment to “quality and efficiency rather than simply pushing for the highest possible volume in the shortest period of time.” Tesla has also stated an anticipated weekly run rate of 2,500 Model 3s by the end of Q1 2018 and 5,000 Model 3s by the end of Q2, well above the 2,425 produced in Q4 2017.

Regarding deliveries, the less-than-anticipated production run is expected to delay Model 3 deliveries by roughly three months more than originally anticipated, with deposits collected throughout 2016. Tesla cited its delivery count as “slightly conservative” with an explanation as to the methodology used to classify a vehicle as “delivered.”

Tesla has long been chastised by a lack of followthrough on its production milestones. In the past, Musk has stated a Model 3 production goal of 5,000 Model 3s per week by the end of 2017, or 500,000 Model 3s a year by the end of 2018. Despite the issue, Tesla’s stock price has been remarkably resilient, hitting $314.62 during Jan. 4 after hours with a $214.31 52-week low.

Analyst projections have been mixed, with predicted delivery numbers varying wildly from 800 upwards of 5,000, in a rough approximation.
