Is Tesla Stock Still Worth Owning After Its Quarter?

Tesla (TSLA) stock fell 3.1% the day after the company reported its Q3 FY2026 results on October 21, 2026, while the S&P 500 lost 1.2%. Buyers pay about 375 times trailing earnings for Tesla shares. That price may be a bet on its Robotaxi business and Optimus robot more than on cars. Management said Tesla plans to fund its 2026 capital spending mostly from operating cash. So how much of its Q3 FY2026 revenue did Tesla keep as profit?

Tesla Kept Less Profit From Each Dollar Of Sales

Tesla turned 2.6% of its Q3 FY2026 revenue into operating profit, compared with 6.6% in Q3 FY2025. Operating profit measures the money left after the costs of making products and running the company. Revenue of $28.0 billion was almost unchanged from Q3 FY2025 and came in 1.4% below the analysts’ consensus. On the earnings calendar’s measure, which differs from Tesla’s filings, earnings per share of $0.48 beat the analysts’ estimate by 10.1%. Net income reported in Tesla’s filings was $0.79 billion, or about $0.22 a share.

Tesla earned more on the products themselves. Gross margin measures the share of sales left after production costs, and that figure rose to 19.6% from 18.0% a year earlier. The thinner profit therefore came from the costs of running the company, which grew as a share of sales.

Has Tesla’s Profit Been Shrinking For Years?

Yes. Tesla’s operating margin over twelve months fell from 11.2% in the period ended September 2023 to 8.5% a year later. The metric fell again to 5.1% in the twelve months ended September 2025, and to 3.5% in the latest twelve months. Revenue in those latest twelve months rose 8.3% to $104 billion. The company is selling more than a year ago while keeping less of each dollar.

The quarter just reported did improve on the one before it. Operating margin was up from 1.4% in Q2 FY2026, meaning the decline has not run in a straight line.

What Did Tesla’s Management Say About Rising Costs?

During the October 21 call, management said Tesla is in a huge investment cycle and that operating expenses will keep growing until it commercializes its new products. Tesla now expects capital spending of about $20 billion in 2026. During the quarter, Tesla secured the ability to borrow up to $30 billion to support expected growth in capital spending. Management said it does not plan to draw on it in 2026.

When asked on the call how Robotaxi would turn into revenue, management said it would probably become noticeable in Q2 2027 and a big deal by Q3 or Q4 2027. Management also said Tesla will start sharing more figures on its FSD software, revenue included, as that business grows. The quarter leaves the case for owning Tesla resting on its new products. Costs are rising now ahead of the revenue management expects from those products.

Tesla’s operating margin is the number to watch when the company reports its Q4 FY2026 results, expected in January 2027.

How To Act On TSLA?

Not necessarily on Tesla alone, if your goal is long-term wealth. Wealth is built by owning the companies that keep outperforming, the leaders of their industries, wherever they are. In Tesla’s own industry, General Motors stock rose 37% over the five years to October 2026, while Tesla stock rose 23%.
