Tesla reported a significant increase in Q1 revenue and profit year-over-year, largely due to increased automotive revenue and other services, including subscriptions to its Full Self-Driving advanced driver assistance system. The company's shares rose 4% following the release of its earnings report. Revenues of $22.38 billion, a 16% increase from the $19.3 billion generated in Q19.09, and automotive revenue rose to $16.2 billion, compared to $13.96 billion the same year-ago period. However, Tesla's business faced significant headwinds in 2025, with profits decreasing 46% year-to-year to $3.8 billion due to lower EV sales. Despite these improvements, Tesla still relies heavily on its traditional EV business and service and subscription services.
