On October 21, 2026, Tesla announced its financial results for the July–September 2026 quarter. Revenue was $28.046 billion, roughly flat from a year earlier, but net income attributable to common stockholders under U.S. generally accepted accounting principles (GAAP) fell 43% year over year to $787 million. Tesla also revealed that it has begun producing its Optimus humanoid robot at its factory in Fremont, California. While the new business has reached the stage of making actual products, the company as a whole continues to see profits squeezed, as the increase in operating expenses far outpaced the increase in gross profit. The key question going forward is whether Tesla can turn its investments in AI and robotics into future revenue.
Gross profit rose 9%, but surging operating expenses cut operating income by 56%
How Tesla's results look depends heavily on which profit measure is used. According to Tesla's official earnings materials, GAAP net income attributable to common stockholders fell 43%, from $1.373 billion a year earlier to $787 million. By contrast, non-GAAP net income, which adjusts for items such as stock-based compensation and unrealized gains and losses on digital assets and investments, was $1.697 billion, a decline of just 4% from a year earlier. Adjusted diluted earnings per share (EPS) were $0.48. Because GAAP and non-GAAP figures include different items in their calculations, the 43% and 4% declines should be understood as based on different standards.
Operating income shows more clearly what hurt Tesla's profitability. Revenue slipped slightly from $28.095 billion a year earlier to $28.046 billion, while gross profit increased. However, operating expenses, including research and development, grew even more, and operating income dropped sharply. Based on Tesla's unaudited consolidated results, the differences from a year earlier are as follows:
| Item (US$ millions) | Jul–Sep 2025 | Jul–Sep 2026 | Change YoY |
|---|---|---|---|
| Gross profit | 5,054 | 5,494 | +440 |
| Operating expenses | 3,430 | 4,776 | +1,346 |
| Operating income | 1,624 | 718 | −906 |
Gross profit rose 9% year over year to $5.494 billion, an increase of $440 million. Operating expenses, however, rose $1.346 billion to $4.776 billion, up 39% from a year earlier. As a result, operating income fell by $906 million to $718 million. In other words, operating income declined because the increase in operating expenses exceeded the increase in gross profit. The operating margin also fell from 5.8% a year earlier to 2.6%, sharply narrowing profit as a share of revenue.
Research and development spending stood out in the increase in operating expenses. It rose about 69%, from $1.63 billion a year earlier to $2.761 billion, and drove the overall rise in operating expenses. Tesla cited R&D in areas such as AI, which it calls "Super Intelligence," along with higher stock-based compensation and selling, general and administrative expenses, as factors behind the decline in operating income. However, the company has not disclosed the full increase in R&D spending by business, so it cannot be assumed that the entire increase corresponds to Optimus development costs.
Vehicle deliveries fell 2%, with battery supply limiting production growth
In the automotive business, deliveries to customers totaled 486,532 vehicles, down about 2% from 497,099 a year earlier. Tesla said its passenger vehicle order backlog has reached its highest level in four years, and it pointed to battery supply shortages as the main factor currently limiting production increases. For this reason, the decline in deliveries alone cannot be taken as proof that demand has weakened. At the same time, it would not be appropriate to conclude that all concerns about demand have been resolved based solely on the company's explanation of the growing backlog and battery supply.
Automotive segment revenue fell 3% year over year to $20.56 billion. Notably, revenue from sales of regulatory credits fell sharply, from $417 million a year earlier to $113 million. Excluding this credit revenue, however, the automotive gross margin was 18.1%, up from 15.4% a year earlier and 16.3% in the previous quarter. Tesla said improvements in the mix of sales regions and vehicle models, along with an increase in subscriptions to its driver-assistance feature FSD, contributed to better profitability. It added, however, that lower average selling prices offset part of that effect.
In the energy business, revenue fell even though battery storage deployments increased. Storage deployments rose about 10%, from 12.5 GWh a year earlier to 13.7 GWh, while energy segment revenue fell 16% to $2.881 billion. Tesla cited tariff-related refunds to customers as one factor behind the decline in revenue. For this reason, it cannot be concluded from a simple division of revenue by deployments that the unit selling price of storage batteries fell by the same proportion.
By contrast, the services and other segment, which includes charging, insurance and parts sales, continued to grow. Revenue rose 33% year over year to $4.605 billion, and gross profit reached $734 million. According to Tesla, growth in charging, insurance and parts sales supported the expansion. While revenue in the automotive and energy segments declined, businesses tied to services after vehicle sales increased revenue and gross profit, showing that earnings trends differ by business.
Optimus enters production, reaching a new stage on the road to commercialization
The start of production of the Optimus humanoid robot was a notable development in this report. Tesla announced that it has begun manufacturing Optimus on a mass-production line at its Fremont, California facility. According to the company, the units completed on this line are the first product-quality Optimus robots Tesla has built. Tesla said it will continue to refine the hardware and manufacturing processes, but has confirmed that the current manufacturing approach is suitable for a commercial product.
Starting production, however, is not the same as being able to build and sell sufficient volumes reliably. Tesla's earnings materials describe Optimus production in California as in "Early Ramp," and its production facility in Texas is under construction. The announcement did not disclose specific production or sales volumes, nor Optimus's standalone revenue or profit and loss. While it is clear that progress has been made in establishing a manufacturing process for commercialization, it is not yet possible to assess production scale or profitability.
Other new products are at different stages of development and commercialization. The Tesla Semi heavy-duty electric truck has begun volume production in Nevada, and the dedicated robotaxi Cybercab entered the ride-hailing service in Austin, Texas, on September 3. The next-generation Roadster, unveiled on October 15, is listed in the earnings materials' manufacturing status table as in design and development, with no manufacturing site decided. Starting production, deploying a vehicle in a service and unveiling a new model each represent different stages of commercialization, and none of them immediately implies a contribution to earnings.
It is also important not to confuse a facility's annual production capacity with actual production volume. For example, the Tesla Semi's annual production capacity is listed as 25,000 units, but that reflects the capability of installed equipment and is not the current annual production rate. Tesla also notes that capacity and actual production rate differ and can be constrained by factors such as parts supply and equipment utilization. For Optimus as well, evaluating any future ramp-up will require checking actual production results and sales.
In the software business, meanwhile, growth in subscriptions is already showing up in concrete numbers. Active FSD subscriptions rose 67% year over year to 1.74 million, and more than 75% of new deliveries in North America came with FSD. However, active subscriptions include both one-time purchases and monthly subscriptions, while free trials are excluded from the count. The figure of 1.74 million therefore cannot be interpreted to mean that 1.74 million subscribers pay monthly fees. The share of more than 75% of new deliveries also applies only to the North American market and cannot be applied as is to global vehicle sales or the existing fleet.
FSD (Supervised) is a driver-assistance feature that requires constant driver supervision and does not mean the vehicle drives fully autonomously. Because its functions and operating conditions differ from those of Robotaxi, which operates without a supervisor, usage results for the two should not be conflated. Although FSD subscriptions are growing, judging how much revenue and profit that growth will generate will also require checking the contract structure and the status of revenue recognition.
Free cash flow returns to positive; year-end capital spending is the focus
Looking at cash flow, Tesla's free cash flow was positive at $1.531 billion, recovering from a negative $1.092 billion in the previous quarter. Free cash flow is operating cash flow minus capital expenditures, and it is a measure of the relationship between the cash a business generates and its investment burden. However, it is down 62% from $3.99 billion a year earlier, so the return to positive territory does not mean Tesla has regained cash-generating power on par with last year.
Operating cash flow for July–September was $6.263 billion, up from $4.697 billion in the previous quarter. Capital expenditures fell from $5.789 billion in the previous quarter to $4.732 billion, and this reduction in spending also helped free cash flow return to positive. Still, capital expenditures were about 2.1 times the $2.248 billion of a year earlier, so the burden of investment in AI, robotics, manufacturing equipment and other areas remains heavy.
The focus going forward is the scale of capital spending toward the end of 2026. In its second-quarter report filed with the U.S. Securities and Exchange Commission (SEC) in July, Tesla indicated that 2026 capital expenditures would exceed $25 billion. However, the combined capital expenditures for the first through third quarters listed in the latest earnings materials total $13.014 billion. If that outlook is maintained, it implies capital spending of more than $11.986 billion in the fourth quarter alone.
This figure is the annual outlook of $25 billion minus the nine-month actual results, and is not a new fourth-quarter capital expenditure forecast announced by Tesla. Even so, it means capital spending would need to increase sharply toward year-end to meet the original annual plan. Electrek's Fred Lambert also pointed to this gap, noting the need to determine whether spending will surge in the fourth quarter or some investment will slip into 2027 or later. Holding back capital spending makes short-term free cash flow easier to improve, but that alone does not mean investment efficiency has improved or that development plans are delayed.
Tesla is also the subject of a possible merger with SpaceX. According to The Verge, the two companies each set up special committees to consider a possible merger. However, neither a merger nor its terms has been decided, and whether it will actually materialize remains unclear. Apart from such speculation about corporate restructuring, the question remains of how Tesla will recoup its own investments in AI, robotics and manufacturing facilities through future revenue.
Tesla ended the July–September quarter with $45.447 billion in cash, cash equivalents and short-term investments, maintaining a degree of financial flexibility. But having ample cash on hand is a separate matter from whether large-scale investment will generate profit. Optimus has reached the milestone of production, but its actual sales scale and profitability remain unclear. Key factors to watch from here include the ramp-up of Optimus production and sales results, growth in FSD-related revenue, gross profit improvement that matches rising R&D spending, and the effect of year-end capital spending on cash flow. As new businesses get under way, whether Tesla can generate revenue that exceeds the investment burden will shape its future performance.
