UBS Warns Tesla Investors

Tesla’s Auto Business Faces Challenges as Wall Street Focuses on AI Ambitions

Tesla (TSLA) has long been a symbol of innovation in the automotive industry, but recent developments suggest that the company is no longer seen primarily as a car manufacturer. Instead, investors are increasingly focused on its ambitious projects like Robotaxi, Optimus robots, and full self-driving capabilities. However, this shift in attention has not come without consequences.

According to UBS analyst Joseph Spak, the core issue remains that the car business still needs to function effectively. Currently, it is not performing well enough to support the high expectations set by Wall Street. Spak recently revised his estimate for first-quarter 2026 deliveries to 345,000 vehicles, down from 421,000 delivered in the fourth quarter of 2025 and below the Visible Alpha consensus of 371,000. This downward revision highlights the growing concerns about Tesla’s performance in its traditional market.

UBS maintains its sell rating and $352 price target on TSLA, which implies roughly 8% additional downside given the stock’s closing price of $380.30 on March 19. The stock has already declined by 17% year to date, signaling a broader loss of confidence among investors.

The Core Message: Sentiment vs. Reality

The key takeaway from UBS’s analysis is that while sentiment and AI narratives drive TSLA’s stock price, the auto business remains the foundation of everything else. This dynamic is now under pressure from multiple directions, particularly as Tesla faces challenges in its core operations.

Spak’s revised estimate of 345,000 units represents only 2% year-over-year growth, a significant slowdown for a company that has promised an AI-era transformation. His previous Q1 estimate was 360,000, and the downward adjustment reflects weakness across Tesla’s three largest markets. In the U.S., EV demand has softened, and Tesla is winding down production of the higher-margin Model S and Model X. Early data for January and February shows roughly 78,600 domestic deliveries, a 6% decline compared to the same period last year.

In Europe, deliveries across the top eight markets fell approximately 4% year over year in the first two months of the quarter. While there were gains in Germany and France, sharp declines in the U.K. and the Netherlands offset some of these improvements. In China, domestic retail deliveries fell 6% year over year, although exports surged due to a zero-interest financing promotion that extended through March 31.

Spak notes that deliveries could fall slightly below even his revised estimate unless Tesla makes a meaningful end-of-quarter push, a strategy the company has used before.

Why the Auto Business Still Matters

The tension at the heart of the UBS note is clear: while the stock trades on AI ambition, the cash that funds Tesla’s broader initiatives—such as the Robotaxi program, Optimus humanoid robot, Dojo supercomputer, and a $20 billion capital expenditure budget for 2026—comes almost entirely from selling cars. As Spak points out, the auto business is the primary source of Tesla’s cash flow and investment for growth. Weaker deliveries not only disappoint on a headline number but also compress margins and cash flow, which are essential for sustaining the company’s growth engine.

Tesla’s gross margins have already slipped to 16.8% in the fourth quarter of 2025, driven by ongoing price competition, particularly from Chinese rivals like BYD. While the energy storage segment offers some relief, with Spak projecting 15.1 gigawatt-hours of deployment in Q1—an increase of 45% year over year—vehicles still account for the overwhelming majority of operating cash flow. The energy business is growing fast, but it is not yet large enough to compensate if the auto business falters.

The Robotaxi Credibility Problem

UBS is not just concerned about delivery numbers; the report highlights a more structural issue: growing investor skepticism about Tesla’s ability to maintain a competitive advantage in autonomous driving. Recent feedback from investors suggests that updates around Robotaxi and Optimus have been slower and less impactful than expected. At the same time, competition in the autonomous vehicle space has intensified.

Waymo, for example, is now completing more than 400,000 paid rides per week, scaling commercial operations in multiple U.S. cities. Meanwhile, Nvidia’s recent Alpamayo autonomous vehicle platform announcement has raised the bar for what the broader ecosystem can offer. Tesla’s camera-only approach to self-driving, which relies on vision rather than lidar or radar, was once seen as a cost and scalability advantage. However, this framing is now being questioned.

Investors are concerned that Tesla may not be able to sustain a meaningful differentiation in the robotaxi market as more capable and better-funded competitors close the gap.

What Investors Should Watch

UBS outlines several key areas that investors should monitor:

• Q1 delivery results, due on April 2, which will set the tone heading into earnings
• First-quarter earnings on April 28, where margin trends will be closely scrutinized
• Any concrete Robotaxi production or deployment update beyond prototype demonstrations
• Progress on FSD, particularly given an intensifying NHTSA probe into how the system performs in reduced visibility

What This Means for TSLA Investors

UBS is not alone in its caution. The broader analyst community has reached a hold consensus on Tesla, with 13 buy ratings, 11 holds, and seven sells. The average price target of $399.25 implies only modest upside from current levels.

The bull case for TSLA has always relied on the idea that Tesla is not really an automaker but a technology platform with cars as its current revenue base. That argument holds if the AI ventures deliver. However, it becomes harder to sustain if delivery volumes keep slipping, margins stay compressed, and the Robotaxi timeline keeps getting pushed while competitors build real-world scale.

Spak’s note does not say the bull case is dead. It says the auto business cannot be ignored while investors wait for the AI story to play out. Tesla needs both to work. Right now, one of them is not.
