Tesla's assembly lines slowed down during a rocky start to the new year, which will likely magnify nagging doubts about whether the electric car pioneer will be able to make the mass-market leap.
The Palo Alto-based company churned out 77,100 vehicles from January to March, well behind the pace it must sustain to fulfill CEO Elon Musk's pledge to manufacture 500,000 cars annually.
The first-quarter production figures announced late Wednesday lagged the 86,555 vehicles that Tesla manufactured during the final three months of last year when the company was scrambling to make more cars.
That push helped Tesla post a profit in back-to-back quarters for the first time in its 15-year history.
Musk has already warned investors that the company will lose money during this year's first quarter amid cost-cutting needed to lower the price of its Model 3, its first electric car designed for the mass market. The company produced 62,950 Model 3s in this year's first quarter, up from 61,934 in the prior three months.
Musk has acknowledged that Tesla's hopes of becoming a consistent moneymaker are riding on the success of the Model 3 and a sports utility vehicle called the Model Y scheduled to be released next year. And for those vehicles to become hits, Tesla will have to be able to produce them in high volumes at its factories in California and China.
The company only delivered 63,000 vehicles in the quarter, down 31% from 2018's fourth quarter. It cited a big increase in vehicle deliveries to Europe and China and "many challenges encountered for the first time."
The lower-than-expected delivery numbers and "pricing adjustments" will take a bite out of Tesla's first-quarter net income, it said. But it said it ended the quarter with sufficient cash on hand.
Tesla said it still expects to deliver between 360,000 and 400,000 vehicles this year.
The company didn't provide further details on how it fared financially during the first quarter. Its quarterly results are expected to be released late this month or in early May.
The disappointing production figures are coming out amid more uncertainty for a company that seems to be caught in an endless cycle of turmoil.
U.S. stock market regulators are accusing Musk of improperly tweeting about Tesla's manufacturing volume in February when he predicted that the company would make about 500,000 cars this year. A few hours later, he backtracked slightly, saying he meant Tesla would be manufacturing about 125,000 cars per quarter by the end of this year, a pace that would translate into 500,000 vehicles annually.
Either way, the Securities and Exchange Commission alleges Musk's tweet violated a court-approved settlement that called for him to have his tweets about Tesla information pre-approved by the company. That requirement is part of a $40 million settlement reached last year after Musk tweeted he lined up the financing needed to lead a buyout of a Tesla, a claim that the SEC asserted was a misleading statement that duped investors.
Musk has vehemently denied his February tweet violated the settlement and is fighting the SEC's attempt to have him held in contempt of court. U.S. District Judge Alison Nathan is scheduled to hear further arguments about the case during a hearing scheduled Thursday in New York.
