The Austin, Texas, company on Tuesday said quarterly profits fell by 70 per cent to to $US409 million ($A638 million), or 12 cents a share - far below analyst estimates. Tesla's revenue fell nine per cent to $US19.3 billion ($A30.1 billion) in the January through March period, below Wall Street's forecast.
The disappointing results come as the company struggles to sell cars to consumers angry over Musk's leadership of a federal government jobs-cutting group that has divided the country and sparked protests. Musk also has publicly supported far-right politicians in Europe and alienated potential buyers there also.
Many investors have also complained Musk is too distracted with his Trump administration role to be running Tesla and that he should either relinquish his position as CEO or abandon his advisory role in Washington.
Tesla stock has fallen more than 40 per cent in 2025 but rose slightly in after-hours trading.
Morningstar analyst Seth Goldstein said earlier reports of plunging sales that had tanked the stock made the results almost predictable.
"They're not particularly surprising given that deliveries were down," Goldstein said, adding that the company is still generating cash. "It was good to see positive cash flow."
Tesla will hold a conference call to review the quarterly results and give a company update later Tuesday afternoon.
Tesla investors will be listening closely for updates on several strategic initiatives. The company is expected to roll out a cheaper version of its best-selling vehicle, the Model Y SUV later in the year. Tesla has also said it plans to start a paid driverless robotaxi service in Austin, Texas, in June.
The company that once dominated EVs is also facing fierce competition for the first time.
Earlier in 2025 Chinese EV maker BYD announced it had developed an electric battery charging system that can fully power up a vehicle within minutes. And Tesla's European rivals have begun offering new models with advanced technology that is making them real alternatives, just as popular opinion in Europe has turned against Musk.
Investors expect Tesla will be hurt less by the Trump administration's tariffs than most US car companies because it makes most of its US cars domestically. But Tesla won't be completely unscathed. It sources some materials from abroad that will now face import taxes.
Retaliation from China will also hurt Tesla. The company was forced earlier this month to stop taking orders from mainland customers for two models, its Model S and Model X. It makes the Model Y and Model 3 for the Chinese market at its factory in Shanghai.
