Teslas global sales rose 2.3% in the fourth quarter after a sluggish start to the year that contributed to the electric car companys first year-over-year sales decline since at least 2015.The annual decline for the Austin, Texas, company came despite offers such as 0% financing, free charging, and low-priced leases.Tesla delivered 495,570 vehicles from October through December, boosting deliveries to 1.79 million for the full year. But that was 1.1% below 2023 sales of 1.81 million as overall demand for electric vehicles in the U.S. and elsewhere slowed.The fourth-quarter boost came with a cost. Analysts polled by FactSet expected Teslas average sales price to fall to just over $41,000 in the quarter, the lowest in at least four years.That doesnt bode well for Teslas fourth-quarter earnings, which the company said it would announce on Jan. 29.In 2022, Tesla predicted that its sales would grow 50% most years, but the prediction ran into an aging model lineup and increased competition in China, Europe, and the U.S. In the U.S., analysts say most early adopters of technology already have electric vehicles, and more mainstream buyers have concerns about range, price, and the ability to find charging stations on longer trips.The fourth-quarter deliveries fell short of Wall Street estimates. Analysts polled by data provider FactSet expected sales of 498,000 vehicles.Tesla shares fell 5.2% in trading early Thursday, but shares are up more than 50% over the last 12 months, surging with the election victory by Donald Trump.Falling sales early in the year led to once-unheard-of discounts for the automaker, cutting into its industry-leading profit margins.Competition from legacy and startup automakers is also growing as they try to nibble away at the companys market share.Nearly all of Teslas sales came from the smaller and less-expensive Models 3 and Y, with the company selling only 23,640 of its more expensive models including X and S, as well as the new Cybertruck.Teslas global electric vehicle sales edged out Chinese rival BYD, which announced Thursday that the total soared 41% last year including 1.77 million EVs. The company is vying with Tesla for the worlds top-selling EV maker.Fourth-quarter production of 459,445 vehicles was below total deliveries for the quarter, and full-year production of 1.77 million was less than the years sales.
