Tesla stock tumbled in after-hours trading after the electric vehicle manufacturer announced a substantial miss on earnings for the second quarter of 2026. While the company reported record revenues of $28.24 billion, surpassing analyst expectations, its adjusted earnings per share (EPS) came in at $0.33, significantly short of the consensus estimate of $0.49. This earnings shortfall, a decline of 17.5% year-over-year, overshadowed the top-line growth and sent shockwaves through the market.
The miss on profitability is attributed to several factors, including a sharp increase in operating expenses, which surged 47% to $4.35 billion. This rise in costs is largely due to heavy investments in artificial intelligence, the Optimus robot, and robotaxi initiatives, as well as increased stock-based compensation. Furthermore, Tesla's revenue from regulatory credits, a historically significant source of profit, saw a dramatic decrease, falling 67% year-over-year to $146 million. This combination of increased spending and decreased credit revenue significantly impacted the company's bottom line, leading to a substantial drop in operating income and margin.
The financial results also revealed a negative free cash flow of $1.09 billion for the quarter, the first time this has occurred in two years. This cash burn is a direct result of capital expenditures more than doubling to $5.8 billion, as Tesla continues its aggressive investment in future technologies and production capacity. While Tesla achieved record vehicle deliveries and saw growth in its energy and services businesses, the persistent pressure on margins and the substantial investments in long-term projects have investors reassessing the company's near-term financial outlook.
