• Revenue: $28.05 billion (nearly flat year-over-year, roughly in line with market expectations)
• Adjusted EPS: $0.48 (exceeding market expectations of $0.45)
• GAAP EPS: $0.22 (a significant decrease from $0.39 in the same period last year)
• Free Cash Flow: +$1.53 billion (the market expected an outflow of approximately $4.5 billion)
• Stock Price: Oct 21 closing price approx. $387 (+3.5%), rising another ~2% in after-hours trading following the earnings announcement

Earnings Summary

Tesla’s Q3 2026 earnings, released after the U.S. market close on October 21, settled into the assessment that “the numbers look weak, but the substance is better than expected.” Revenue was $28.05 billion, nearly the same level as the same period last year; GAAP net income fell 43% year-over-year to $787 million, and operating income also dropped 56% to $718 million, making it a tough quarter if looking only at profits. However, the cash flow that the market was most wary of landed at a surplus of over $1.5 billion against an expected outflow of about $4.5 billion, and the automotive gross margin also improved significantly from the previous quarter. Adjusted EPS also exceeded expectations at $0.48. The stock price rose 3.5% during regular trading hours after Elon Musk revealed the day before that he was considering a merger with SpaceX, and it continued to be bought in after-hours trading following the earnings announcement.

Overall Earnings Picture: Revenue Flat, Profits Down—Yet Why It Is Evaluated as “Better Than Expected”

If one were to describe Tesla’s earnings this time in a single phrase, it would be “earnings that cleared a low bar in an unexpected way.”

First, as a premise, market expectations were set quite low. Before the earnings, analyst revisions to profit forecasts were overwhelmingly tilted toward downward revisions, with 19 downward revisions versus 4 upward revisions. The reason is clear: Tesla has announced a plan to expand its 2026 capital expenditure to over $25 billion, nearly triple the previous year’s approximately $8.5 billion, and that heavy investment burden was seen as squeezing profits and cash. For the July-September quarter, it was generally expected that free cash flow (FCF) would be a negative of about $4.5 billion and capital expenditure would be about $7.8 billion.

However, when the lid was opened, FCF reached a positive $1.53 billion, and operating cash flow reached $6.26 billion. Considering that FCF in the previous quarter (April-June) was a negative of about $1.1 billion, it can be said that cash generation capacity has clearly recovered. The balance of cash and short-term investments also increased by about $1.9 billion from the end of the previous quarter to $45.45 billion.

What is important here is the substance of “why cash was better than expected.” The biggest reason is that capital expenditure was $4.73 billion, about $3 billion below market expectations. It also decreased by about 18% from the previous quarter’s $5.79 billion. In other words, the main cause of the surprise was not that earnings suddenly increased, but that “money that was supposed to be spent was not spent.”

This point is interpreted very differently by bulls and bears. From the perspective of bulls, it is proof that investment efficiency and expenditure management have progressed, and it is a sign of management discipline that can protect cash even in a massive investment phase. On the other hand, from the perspective of bears, it is also a sign that plans such as Optimus (humanoid robot), Cybercab (dedicated robotaxi vehicle), AI computing infrastructure, and the semiconductor factory “Terafab” being built in collaboration with SpaceX may be delayed more than expected. Tesla still expects capital expenditure of over $25 billion for the full year, and if so, spending will be concentrated in the October-December quarter. This good cash flow might not be “advance peace of mind” but rather “postponed burden.” This perspective is something to keep in mind when reading the next earnings report.

In terms of profit, while adjusted (non-GAAP) net income was $1.7 billion, GAAP net income remained at $787 million. A major factor in this difference is stock-based compensation expenses, which also includes the impact of the massive compensation package for Mr. Musk. Adjusted EPS improved from $0.33 in the previous quarter to $0.48, and while adjusted net income increased by 47% from the previous quarter, GAAP net income decreased by 29% from the previous quarter. It is necessary to be aware that the impression of the earnings changes completely depending on which number is emphasized.

Automotive Business: The Meaning of Improved Gross Margin Even When Sales Are Below the Previous Year

Automotive segment revenue was $20.6 billion, down 3% from the same period last year. Deliveries for the July-September quarter were 486,532 units, a decrease of about 2% from 497,099 units in the same period last year. However, the market expectation was just over 460,000 units, so deliveries themselves significantly exceeded expectations. This is a slight increase from 480,126 units in the previous quarter.

On the other hand, production was limited to 464,391 units, which was more than 20,000 units below deliveries. This means that inventory was drawn down to make sales. Tesla explained that it has the “largest order backlog in the past four years” at the end of the quarter, and the structure is that battery supply is a bottleneck for production rather than a lack of demand. The company stated that it has made additional progress in strengthening its battery supply chain.

What should be noted is the improvement in profitability. The automotive gross margin excluding regulatory credits was 18.1%, a significant improvement from 16.3% in the previous quarter and 15.4% in the same period last year. The GAAP-based automotive gross margin also rose to 18.5% from 16.9% in the previous quarter. The company-wide gross margin also exceeded market expectations at 19.6%. This is an improvement in profit margin while the average selling price is falling, and it is seen that cost reductions and improvements in production efficiency are working. Since warranty-related expenses were a burden in the previous quarter, the recovery from that gave investors a certain sense of relief.

However, it is not all optimism. Regulatory credit revenue was $113 million, down about 70% from $417 million in the same period last year. The “emission credit revenue obtained from other companies” that once supported Tesla’s profits continues to shrink along with the retreat of U.S. environmental regulations. This means that the company has entered a phase where its ability to earn solely from its core vehicle sales is being questioned more.

Looking by region, the weakness of the U.S. market stands out. In the U.S., the $7,500 EV tax credit ended last year, and there was a rush in demand just before that. Partly due to the reaction to that, research firm estimates suggest that U.S. sales in the July-September quarter were about 144,100 units, a decrease of nearly 20% from the same period last year. Even so, Tesla’s share of the U.S. EV market is about 54%, exceeding the total of all other brands combined. On the other hand, record-high deliveries were recorded in Canada, Australia, Japan, and Taiwan. The structure of compensating for the decline due to the end of U.S. subsidies with overseas markets has become clear.

Also, in this quarter, Tesla has reached the milestone of 10 million cumulative production and deliveries. It is a record that once again shows the scale of the company as an EV-only manufacturer.

Energy and Services Business: Two Pillars with Contrasting Fortunes

In businesses other than automotive, the fortunes were clearly divided.

Revenue from the energy generation and storage business was $2.88 billion, down 16% from the same period last year. The company explained that refunds to customers related to tariffs had some impact. Although the deployment of battery storage increased to 13.7 GWh from 12.5 GWh in the same period last year, it did not reach the market expectation of 15.9 GWh. As the energy business has been evaluated as Tesla’s “hidden growth engine,” this revenue decline is a slightly disappointing result.

However, leading indicators are not bad. Tesla stated that it recorded “record-high order pace and backlog” in the battery storage business. Also, the new Megafactory in Texas began production with a planned capacity of 50 GWh per year, and the Nevada factory shipped its first Megapack consisting solely of LFP (lithium iron phosphate) cells. A domestic production system to suppress the impact of tariffs is being put in place, and there is sufficient room for recovery from the next quarter onwards.

In contrast, service and other revenue was strong. At $4.6 billion, up 33% from the same period last year, it was the fastest-growing segment in this earnings report. This includes used car sales, insurance, charging, and software-related revenue such as FSD (Full Self-Driving, supervised). The transition to the business model that Tesla aims for, “not selling a car and being done with it, but earning every time it runs,” is beginning to appear in the numbers.

Cost Structure: Operating Income is Half of Expectations—The Weight of AI Investment is Clear

The toughest part of this earnings report was operating income. Operating income was $718 million, a 56% decrease from $1.62 billion in the same period last year, and it remained at about half of the market expectation of about $1.47 billion. The operating margin is only 2.6%.

The cause lies in the rapid increase in operating expenses. Operating expenses swelled to $4.78 billion, up 39% from the same period last year. Tesla cites increased spending on AI and research and development, decreased revenue from regulatory credits and the energy business, and stock-based compensation expenses including Mr. Musk’s compensation package as factors.

What these numbers show is the reality that Tesla is no longer a “high-margin automaker” but is changing into a “company that is reinvesting the profits of its automotive business into AI and robot development.” The reason operating income is decreasing even though the gross margin is improving is that the difference is being diverted to investment in the future.

This is also the core part where investors’ views are divided. If you look at Tesla stock as an automotive stock, an operating margin of 2.6% is clearly low. However, if you look at it as a growth stock in a transition period to an AI/robotics company, the increase in R&D expenses as a percentage of revenue is actually a natural move, and the question is when and how much return that investment will generate. Adjusted EBITDA was $3.9 billion, exceeding the market expectation of $3.66 billion, and the core cash generation capacity itself has not collapsed.

Progress of Future Businesses: What FSD, Robotaxi, and Optimus Have Shown

What explains the majority of the stock price is not the automobile, but the expectations for future businesses. Mr. Musk himself also posted over the weekend just before that Optimus and Cybercab would account for the majority of Tesla’s future corporate value. In this earnings material, several pieces of progress that support those expectations were shown.

FSD (Supervised Full Self-Driving)

This time, what stood out most in terms of software was FSD. Over 75% of new car deliveries in North America were equipped with FSD, an increase of about 20 points from the previous quarter. The number of active FSD subscriptions reached 1.74 million, up 67% year-over-year. In Europe, it was newly approved in Croatia, Slovenia, the Czech Republic, and Slovakia, making it available in a total of 9 EU member countries. In Europe, over 100,000 users have driven a cumulative total of over 160 million km.

The spread of FSD is directly linked to the growth of the service revenue mentioned above. If the structure of continuously earning from a car once sold becomes stronger, it will become a revenue base that is less susceptible to the business cycle of automotive sales. This is likely one of the points that long-term investors should appreciate most in this earnings report.

Robotaxi and Cybercab

Cybercab launched a ride service as a robotaxi in Austin, Texas, on September 3. The cumulative mileage of unmanned (unsupervised) robotaxis increased 8-fold in this quarter, reaching about 2 million miles. Service hours in Austin were expanded from 6:00 AM to midnight, and inside the car, it became possible to manage emails and schedules by voice using xAI’s conversational AI “Grok.” Cybercab production capacity in Texas is said to be over 125,000 units per year.

Robotaxis are already deployed in 6 cities, and in the safety report released the day before the earnings, Las Vegas, Jacksonville, Phoenix, and San Antonio were mentioned as candidates for the next deployment. However, the results of the Cybercab review by the U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) are expected to be released by October 30, and regulatory hurdles still remain.

Optimus (Humanoid Robot)

The humanoid robot “Optimus” has begun production on the mass production line at the Fremont factory in California. The company explains that while it will continue to improve hardware and manufacturing processes, it has proven that the current manufacturing process is suitable for commercial products. Since the release timing of the new Optimus model had been pushed back many times this year, the sentence “manufactured a robot of mass-production quality for the first time” is an important step forward for long-term investors.

Other Progress

The large EV truck “Semi” has entered the mass production stage in Nevada, and the top-tier model has a range of 500 miles at maximum load (about 37 tons). AI training computing power is expected to reach 400 MW by the end of the year, and equipment setup is scheduled for 2027 at the Austin semiconductor factory.

On the other hand, the company did not provide specific sales volume forecasts this time either. It stated that it would focus on maximizing factory utilization, and only indicated the long-term direction that in addition to hardware profits, software and fleet-based profits will accelerate in the future.

Stock Price Trend: The “Two-Stage Rocket” of SpaceX Merger Speculation and Earnings

What is indispensable for understanding the movement of Tesla stock this time is the event that occurred the day before the earnings.

On October 20, at SpaceX’s Q3 earnings briefing, Mr. Musk revealed that at the request of shareholders, both SpaceX and Tesla have established special committees of independent directors and are considering a merger of the two companies. While Mr. Musk said that a merger is a “good idea,” he emphasized that realization is not certain, and stated that he would not be involved in the discussions because he is the CEO of both companies. Also, on the Tesla side, it requires the approval of 50% of all issued shares, not a majority of the shareholders who voted, and he admitted that it is “a quite high hurdle.”

Even so, the market’s reaction was significant. SpaceX’s earnings themselves were strong, with revenue up 161% year-over-year, and SpaceX stock rose around 8% in after-hours trading. Tesla stock also rose from the previous day’s closing price of $373.71 (+1.5%) to the $380 range in after-hours trading, and was bought further in regular trading on the 21st, closing at about $387 (+3.5%). This is the third consecutive day of gains, and it is calculated that the market capitalization increased by about $50 billion in one day. It was also one of the reasons the Nasdaq Composite Index rose 1%.

If the merger is realized, the market capitalization of the integrated company would be about $3.5 trillion, making it one of the top 5 in the world. According to Barclays’ estimates, Mr. Musk would hold about 37% of the integrated company’s shares and about 56% of the voting rights. If realized, it could be the largest corporate merger in history.

And the earnings announced after the close on the 21st took the form of further pushing up the stock price that had risen due to this merger expectation. The upside surprise in adjusted EPS, the improvement in automotive gross margin, and above all, the turnaround to a FCF surplus were well received, and the stock price rose about 2% in after-hours trading, topping the $390 range. In other words, following the first-stage rocket of “SpaceX merger speculation,” the second-stage rocket of “earnings exceeding expectations” was ignited.

However, caution is required regarding valuation. The total EPS for the last four quarters is about $1.08, and the stock price of $387 is at a level exceeding 350 times the trailing P/E ratio. This is an evaluation that cannot be explained by the automotive business alone, and it means that the market is putting a price on the “future story” that includes robotaxis, Optimus, AI, and now even integration with SpaceX. Even as merger discussions become more realistic, JPMorgan maintains its investment rating of “Neutral” and a target price of $415, and Wall Street’s views remain divided.

3 Points Investors Should Keep in Mind

Based on these earnings and the stock’s movement, I will organize the key points to keep in mind when looking at Tesla stock going forward.

Point 1: Is the cash flow improvement ‘discipline’ or ‘delay’?

The FCF surplus was due to capital expenditures falling $3 billion short of expectations. If the full-year investment plan of over $25 billion is maintained, large-scale spending is expected in the October-December quarter. If cash flow swings significantly negative in the next quarter, the current sense of relief could evaporate instantly. Conversely, if they can protect cash while maintaining the plan, the evaluation of Tesla’s management efficiency will rise another notch.

Point 2: Can the automotive business regain its ‘earning power’?

While the improvement in gross margin is a bright spot, headwinds such as the reduction of regulatory credits, the end of U.S. tax credits, and falling average selling prices persist. The fact that the order backlog is at its highest in four years is a positive factor, and if battery supply constraints are resolved, it may become possible to achieve both sales volume growth and margin improvement. The strength of the automotive business as a ‘vault’ to generate funds for investment in future businesses remains crucial.

Point 3: Is a SpaceX merger a plus for shareholders?

If a merger is realized, Tesla shareholders are likely to be converted into SpaceX shares. The exchange ratio at that time will be determined by the valuations of both companies. It should be noted that SpaceX’s strong earnings and stock price rise are not necessarily advantageous for Tesla shareholders. With a high approval hurdle of a majority of all outstanding shares, the road to realization is long. Since the stock price is partly driven by speculation about the merger, it could fluctuate significantly depending on follow-up reports.

Summary

Tesla’s Q3 2026 earnings were characterized by ‘internal strength’—namely, positive cash flow, improved automotive gross margins, and the rapid spread of FSD—contrary to the ‘apparent weakness’ of flat revenue and significantly lower profits.

However, some of that strength was supported by the postponement of capital expenditures, and as the 2.6% operating margin figure indicates, Tesla is currently in the midst of making massive upfront investments toward its transformation into an AI and robotics company. The stock price rose due to the synergistic effect of SpaceX merger speculation and strong earnings, but the valuation of over 350x trailing P/E assumes that future businesses will blossom as expected.

Tesla stock today is not a stock that moves based on an ‘automotive company’s earnings,’ but rather on ‘how close the story of the future has come to reality.’ In that sense, these earnings showed that parts of the story are indeed becoming reality in the form of the start of Optimus mass production, the commercial operation of Cybercab, and the spread of FSD. In the next quarter, will the swelling investments begin to bear fruit in the numbers, or will they weigh heavily as a burden? The next direction for Tesla stock will depend on that answer.
