Tesla blames production setbacks for the Decline in Quarterly Deliveries, but falling demand is the bigger issue. Tesla reported its first year-over-year decline in quarterly deliveries since 2020, badly missing Wall Street's expectations and stoking further concern about the company's growth prospects this year. Elon Musk's electric-vehicle maker delivered 386,810 vehicles globally in the first three months of 2024, down 8.5% from a year earlier. It was the company's lowest quarterly performance since the third quarter of 2022. First, the company halted output at its plant in Germany for two weeks beginning in late January, citing parts shortages stemming from attacks on ships in the Red Sea. Then, in March, the assembly line ground to a halt once more after an arson attack on the grid that supplies power to the factory. Meanwhile, Model 3 production tumbled in the U.S. as the company introduced its refreshed version of the car domestically.
