Tesla's profit fell 43% as spending on AI and robots doubled to $4.7 billion in a quarter

Tesla reported third-quarter results after the bell on Wednesday: revenue of $28.05 billion, essentially unchanged from $28.10 billion a year earlier, and GAAP net income of $787 million, or 22 cents a share. CNBC reported the stock was little changed in extended trading. The company published the full numbers in an 8-K exhibit on SEC EDGAR, and that is where the figures below come from.

The profit drop is bigger than the headline

Some summaries describe net income as down 29%. That is the drop from the second quarter ($1.114 billion). Against the third quarter of 2025, the deck shows $1.373 billion, so GAAP net income fell 43% and earnings per share fell from 39 cents to 22 cents. Operating income fell from $1.624 billion to $718 million, a 56% drop, and operating margin went from 5.8% to 2.6%.

Gross profit actually rose, from $5.05 billion to $5.49 billion, lifting gross margin to 19.6% from 18.0%. What ate it was operating expenses, up 39% to $4.78 billion. A lower tax bill softened the landing: the provision was $152 million on pretax income of $956 million (about 16%), against $570 million on $1.959 billion a year ago (about 29%). Non-GAAP net income, which strips out items such as stock compensation, was $1.697 billion against $1.770 billion, down 4%.

Where the money is going

One number to check: CNBC's text gives capex as $3.73 billion. The deck shows $4.732 billion, and it is the figure that reconciles, since $6.263 billion of operating cash flow minus $4.732 billion leaves the $1.531 billion of free cash flow Tesla reports. The business generated the same operating cash as last year and spent twice as much of it. Cash and short-term investments still rose $1.9 billion to $45.4 billion.

What is working

Deliveries were 486,532, down 2% from a year ago, but production rose 4% to 464,391 and vehicle inventory is down to 11 days of supply. Tesla says battery availability, not demand, limited volume, and that it ended the quarter with its largest passenger-vehicle backlog in four years. Active FSD (Supervised) subscriptions reached 1.74 million, up from 1.04 million a year earlier. Automotive gross margin was 18.5% against 17.0%.

Management said on the call that the robotaxi fleet will start to matter to the financials in 2027, with "a big deal" by the third or fourth quarter of next year, per CNBC. Treat that as management's expectation, not a result. Our earlier look at the Austin launch is in what is actually running.

Who this hits

For anyone holding Tesla, the quarter sets up the argument now in front of the board: a company spending at twice last year's rate on AI and robots, with the merger with SpaceX under review by special committees. Tesla would need a vote of 50% of all shares, which Musk called a "high hurdle." The deal mechanics are in our merger explainer, and the background on the stock is in what is going on with Tesla stock.

For fleet owners, the deck says Semi volume production has started in Nevada, with the top variant rated at 1.7 kWh a mile and 500 miles at full 82,000-pound weight. Those are company specifications, not independent test results. Energy storage revenue fell 16% even as Tesla reports its highest-ever order rate and backlog, so the orders have yet to show up in sales.

What to watch

Whether free cash flow stays positive as capex runs above $4 billion a quarter, whether Tesla's battery supply catches up with its backlog, and what the special committees decide. Tesla's filings are on SEC EDGAR.
