#TeslaQ3EarningsPreview Tesla Q3 earnings preview: the five lines I will read first on Wednesday

Tesla reports third-quarter results after the market closes on Wednesday, October 21. Wall Street is split on how much the quarter even matters, so I built my preview around the five lines that will decide the reaction, plus the price map.

The setup

TSLA closed Friday at $354.72, below its 50-day average of $359.46 and well under its 200-day average of $377.06, and the stock is down 19.4% year to date. The report lands a day after SpaceX reports, so Tesla goes into it with heavy cross-currents.

The consensus

Zacks puts expectations at 44 cents per share on revenue of $27.8 billion, down 12% in earnings from a year ago. Other trackers show 43 cents on $27.90 billion. By my math that means a quarter of roughly flat revenue and shrinking profit, which is why the debate has moved elsewhere.

Line one: gross margin

This is the first number traders will hunt. Consensus for gross margin is 17.7%, against 16.8% in Q2 and 18.0% a year ago. Automotive gross margin excluding credits was 16.3% in the second quarter, down from 26.7% in 2022. A sequential recovery would be welcomed, and a further slide would hurt.

Line two: free cash flow and capex

In Q2, free cash flow was negative $1.092 billion as capital expenditures hit $5.789 billion, up 142%, against operating cash flow of $4.7 billion and cash of $43.5 billion. Management expects 2026 capex above $25 billion and spending to keep growing for two to three years. Most previews expect another negative quarter, so the question is how large and how it will be funded.

Line three: the operating income squeeze

Zacks expects total operating income to fall more than 68% on higher cost of revenue, R&D and SG&A, with energy revenue estimated at $3.7 billion, up 10%. That is a big drop, and it is the number that could surprise on either side.

Line four: delivery quality

Volume looks good on the surface. Q3 deliveries of 486,532 beat estimates for the second consecutive quarter, but inventory did the heavy lifting. A beat in units does not guarantee a beat in profit, so margins and pricing commentary matter.

Line five: autonomy and Optimus

This may be the real catalyst. Goldman Sachs said updates on Full Self-Driving, robotaxi and Optimus are likely to matter more to the stock than earnings per share. As of Q2, robotaxi was live in seven major metros, Cybercab production had begun, and construction for Optimus production at Fremont was underway, with production anticipated later this year. Regulatory scrutiny of robotaxi is also a risk to watch. The valuation case leans on these: Morningstar values the stock at $450, attributing roughly $135 of that to robotaxi.

The price map

Options traders expect a move of about 7.48% after the results, above the average post-earnings move of 5.95%, and the stock has fallen after each of the last three reports, including a 14.52% drop after July's results. On $354.72, a 7.48% move implies a range of roughly $328 to $381 by my calculation. Goldman is Neutral with a $360 target, while the average target is $404.87. The levels I am watching are $355 as support, $359.46 and $377.06 as resistance.

Three scenarios

Constructive: margins recover from Q2, capex is explained with a funding path, and robotaxi and Optimus timelines get firmer. That can lift the stock toward the 200-day average near $377.

Neutral: numbers land near consensus, the call stays vague, and the stock trades within the implied range.

Cautious: automotive margins slip again, capex guidance rises and the cash deficit widens. Then $355 gives way, and the $328 area comes into view.

The wild card

SpaceX reports on Tuesday, and Tesla shareholders may hear SpaceX mentions, with merger speculation hanging over both stocks. Prediction markets have put merger odds above 50% for early 2027, though no deal has been announced. The market backdrop is shaky, with the Nasdaq coming off a nearly 5% weekly loss and the Fed meeting on October 27-28.

How I would approach it

I would not trade the headline EPS. I would watch margin, free cash flow and the language on autonomy, keep position size small because of the 7.5% implied move, and avoid leverage into the release. The first reaction often reverses, so patience helps.

Share your read: which line matters most to you, and where do you see TSLA after the call. I would like to compare notes with the Square.
