Key Highlights

  • Tesla fell 6% on Sept. 4 after its Sept. 3 Cybercab event, which was not livestreamed and left pricing, production cadence and approvals unanswered, per RBC.
  • NHTSA opened an Audit Query on Sept. 4 into Tesla's self-certification that the Cybercab, which lacks traditional controls, meets federal safety standards.
  • Q2 Revenue rose 26% to $28.24 billion, but adjusted EPS of 33 cents missed estimates, the Operating Margin fell to 1.4% and free Cash Flow turned negative.
  • Shares were recently trading near $379, well below their 52-week high of about $499, as the stock trades at more than 320 times Earnings on hopes for autonomy and robotics.

Tesla, Inc. (NASDAQ:TSLA) is under pressure because the Cybercab launch investors had waited for delivered a product but not the Business details needed to value it. The event on Thursday, Sept. 3, gave no price and no production timeline, and on Sept. 4 the federal auto safety regulator opened an inquiry into how Tesla certified the vehicle as road-legal. Tesla shares fell 6% on Sept. 4, while the S&P 500 and Nasdaq Composite slipped 0.4% and 0.3%, respectively.

The format of the event made the gaps more noticeable. Chief Executive Elon Musk did not attend, the audience was limited to a small group of shareholders and content creators under nondisclosure agreements, and, unlike most Tesla product events, it was not livestreamed. RBC Capital Markets said the event left "key outstanding questions around pricing, production cadence, and regulatory approvals" unanswered.

That combination matters because a large part of Tesla's valuation rests on autonomy rather than on today's car sales. The stock trades at more than 320 times earnings, a multiple that assumes unproven businesses such as robotaxis and humanoid robots succeed at scale.

What NHTSA Is Examining

On Sept. 4, the National Highway Traffic Safety Administration said it had opened an Audit Query into Tesla's certification that the Cybercab meets all applicable Federal Motor Vehicle Safety Standards. The agency said the action followed Tesla's commercial deployment of driverless Cybercab vehicles in Austin, Texas.

Automakers in the U.S. certify their own vehicles as compliant, subject to NHTSA oversight. The audit will review the technical data and processes Tesla used to self-certify a vehicle that lacks traditional human controls, such as a steering wheel and pedals. NHTSA said it will also examine whether Tesla's compliance approach relied on determinations that certain standards do not apply to its automated vehicles.

The regulator's tone was measured. "NHTSA fully supports the safe development and deployment of automated vehicles. But as the federal regulator, we need to ensure that all of our laws are followed," Administrator Jonathan Morrison said. The agency added that it is working on eight rulemakings to update standards covering items such as brake pedals, windshield wipers, lighting and rearview mirrors, but that "existing standards remain in force" until that work is finished. An Audit Query is an information-gathering step and does not by itself mean a recall or penalty will follow.

Second-Quarter Results Show the Cost of the Pivot

Tesla's most recent results, released July 22, showed revenue growth alongside falling profitability. Revenue for the second quarter rose 26% year over year to $28.24 billion, ahead of the $25.71 billion analysts expected, according to LSEG data. Adjusted Earnings Per Share of 33 cents fell well short of the 51-cent consensus. GAAP Net Income declined 5% to $1.11 billion, or 32 cents a share.

Automotive revenue rose 23% to $20.52 billion, supported by record second-quarter deliveries, according to the company. Energy generation and storage revenue increased 13% to $3.14 billion, and services and other revenue jumped 50% to $4.58 billion. Tesla said trailing 12-month revenue exceeded $100 billion for the first time.

Margins moved in the wrong direction. Gross margin slipped to 16.8% from 17.2%, below the 19.4% StreetAccount estimate, as average selling prices and regulatory Credit revenue fell. Operating expenses rose 47% to $4.35 billion, cutting the operating margin to 1.4% from 4.1%. Capital expenditures soared 142% to $5.79 billion, pushing free cash flow to a Deficit of about $1.1 billion. CFO Vaibhav Taneja had said in April that 2026 capex would top $25 billion, and he told investors in July that operating expenses will "grow in 2026 and beyond."

Autonomy, Robots and the Competitive Field

Tesla is shifting its focus from selling vehicles toward its Robotaxi service, Cybercab production and Optimus humanoid robots. In July, the company said active Full Self-Driving (Supervised) subscriptions rose 56% in the quarter to 1.48 million, and that it had begun Cybercab production and was installing first-generation Optimus lines. On the earnings call, Musk urged caution about autonomy: "If we injure even one person, it will be worldwide headline news, and regulators will immediately clamp down on our activities." Ashok Elluswamy, Tesla's vice president of Autopilot, said the Robotaxi fleet runs the "v. 15" build of FSD software and that Cybercab will use the same version. It was not clear when Cybercab would be deemed safe and available for individual buyers.

The competitive picture is demanding. Alphabet's (NASDAQ:GOOGL) Waymo and Baidu's (NASDAQ:BIDU) Apollo Go are well ahead in commercial driverless ride-hailing, while Chinese automakers such as BYD, Nio (NYSE:NIO) and Xiaomi continue to compete on price and technology in the core car business.

Risks on the Road Ahead

  • Regulatory: The NHTSA audit could require changes, delay a wider Cybercab rollout or lead to further enforcement, although no outcome has been announced.
  • Commercial clarity: Without a price or production cadence, analysts have little basis for estimating when Cybercab will contribute meaningfully to revenue.
  • Profitability: An operating margin of 1.4% and negative free cash flow leave limited cushion while capex runs above $25 billion a year.
  • Valuation and sentiment: A multiple above 320 times earnings leaves the stock exposed to disappointments, and Tesla has trailed the other Magnificent Seven stocks in 2026.

The shares were recently trading near $379, well below their 52-week high of about $499.

Tesla's October Delivery Report Looms

The next hard data point is Tesla's third-quarter production and delivery report, which the company usually publishes in the first days of October. Full third-quarter results, typically released in late October, should show whether margins and free cash flow have stabilized under the heavier spending plan.

Investors will also watch for any Tesla response to NHTSA's audit, for progress on the agency's rulemakings on vehicles without manual controls, and for any company disclosure of Cybercab pricing, production volumes or expansion beyond Austin.
