Tesla saw its first delivery decline in nearly four years, missing Wall Street estimates, signaling waning effects of price cuts amid increased competition and softer demand. The car maker’s shares dropped nearly 30% this year, with deliveries down 20.2% from the previous quarter, attributed partly to production adjustments and disruptions in Berlin. Despite facing stiff competition in China, Tesla surpassed BYD’s sales, delivering 369,783 Model 3 and Model Y vehicles. Tesla had previously cautioned of reduced sales growth as it focuses on next-gen electric vehicle production.
