Tesla Q3: Margins Rebound as Profit Slides on AI Spending

Tesla’s third-quarter financials reveal a company balancing a recovery in profitability against a significant increase in operational costs. The electric vehicle giant released its results after the market closed on Tuesday, October 21, providing a snapshot of its performance amid shifting industry dynamics.

Revenue for the quarter landed at $28.05 billion, a figure that remained essentially flat compared to the same period last year. This result aligned closely with Wall Street expectations, which had projected $28.06 billion in sales. However, the profit picture was more nuanced. Non-GAAP earnings per share reached $0.48, surpassing the consensus estimate of $0.45, yet still representing a 4% decline from the $0.50 reported a year ago.

The primary driver behind the dip in operating income, which fell 56% to $718 million, was a sharp rise in spending on artificial intelligence and the Optimus robot. Operating expenses climbed 39% year-over-year to $4.78 billion. Research and development costs jumped 69% to $2.76 billion as Tesla accelerated work on its “Super Intelligence” initiatives, the Optimus humanoid, and the Cybercab. Additionally, stock-based compensation surged to $1.17 billion, up from $663 million in the prior year, largely due to the CEO’s 2025 pay package.

Automotive gross margin excluding regulatory credits recovered to 18.1%, up from 16.3% in the second quarter. Management attributed this improvement to a better product mix and increased revenue from Full Self-Driving subscriptions. Conversely, energy generation and storage revenue dropped 16% to $2.88 billion, partly due to tariff-related refunds to customers, despite a 10% increase in energy deployments. The services segment emerged as a bright spot, with revenue growing 33% to $4.61 billion and gross profit hitting a record $734 million.

Tesla cited battery availability as the main constraint on vehicle volume, noting that it ended the quarter with the largest passenger vehicle backlog in four years. Deliveries totaled 486,532 units, a 2.1% year-over-year decline, though this figure exceeded analyst expectations. The company also reported that active FSD subscriptions reached 1.74 million, a 67% increase, while its Robotaxi service accumulated nearly 2 million unsupervised miles. Capital spending for the quarter was $4.73 billion, more than double the amount spent in the same period last year, bringing the year-to-date total to $13.01 billion.

With the 2026 capital expenditure guidance set at over $25 billion, Tesla faces a significant hurdle to meet its target. The company would need to spend approximately $12 billion in the fourth quarter alone, more than double its highest spending quarter to date. Management has not updated this guidance in the shareholder letter, leaving investors to watch closely whether Q4 spending will surge or if the 2026 plan will shift into next year.

The full shareholder deck is available on Tesla’s investor relations site. Management is scheduled to discuss these results in detail during an earnings call scheduled for 5:30 p.m. ET today, where they will address the strategic implications of the spending ramp-up and the state of the supply chain.
