CEO Elon Musk disappointed investors after warning Tesla could see a second straight year of declining EV sales. He also suggested Q4 could be rough once the U.S. federal tax credits for EV sales expire. All of that might have been acceptable had he provided specific milestones for how quickly he could scale his new autonomous ride-hailing service beyond a dozen cars in Austin. “I wanted to hear more details,” said Gene Munster, cofounder of Deepwater Asset Management.

Tesla shares sold off overnight and Wednesday morning after CEO Elon Musk scrapped his full-year guidance, warned upcoming quarters could prove rough, and hosted an earnings call once again long on promises and short on specifics. The stock was down 9% this morning at the open.

Just over a month ago, the company launched its maiden robotaxi fleet in Austin. The new flagship service crystallized over a decade of investment in artificial intelligence and is meant to be definitive proof the EV maker is now an AI and robotics company.

Yet four weeks later, Tesla has little to show for it. Just 7,000 driverless miles have been logged, Musk’s team revealed in the quarterly call. That works out to 20 miles per car per day, on average.

Shares held steady in after-hours trading following the release of widely expected weak Q2 results that included an 89% drop in net cash generated. But they dipped lower as the earnings call drew to a close with little in the way of answers. They were nearly 6% down as trading began in New York.

“Investors were searching for something and not hearing it,” wrote Gene Munster, cofounder of Deepwater Asset Management and longtime Tesla bull, who counted himself among the disappointed. “I wanted to hear more details about how the master plan will advance in the near term.”

The call was Musk’s first opportunity to present shareholders with a clear road map for his robotaxi service with concrete milestones that specified …

How many vehicles in the fleet he was targeting.
By what time they would be deployed.
How much revenue per ride they would be earning.

Right now, he is charging a flat rate of $6.90, but most expect either a per-mile rate or a dynamic price similar to Uber.

Another key question that went unanswered was when the company felt it would no longer be necessary to employ a human safety monitor in the front passenger seat. Right now, scaling is inhibited by the presence of an onboard babysitter needed to prevent freak occurrences, like the recent case in which a monitor had to stop a Tesla from running a railroad crossing as a train was approaching.

Simultaneously both ‘very cautious’ and ‘hyper-exponential’

Take this statement for example, in which Musk reaffirmed comments earlier this year that his autonomous ride-hailing service would expand to most of the country by year-end.

“We’ll technically be able to do it. Assuming we get regulatory approvals, it’s probably addressing half the population of the U.S. by the end of the year. But we are being very cautious, we don’t want to take any chances—we’re gonna go cautious. The service areas and the number of vehicles in operation will increase at a hyper-exponential rate.”

That was one continuous answer. Broken down, Musk is arguing his four-week-old service that continues to operate with just around a dozen vehicles in one city will—in the course of only five months—expand in a way that is simultaneously both “very cautious” as well as “hyper-exponential.”

“In the meanwhile, we’ll launch a service with a person in the driver’s seat just to expedite while we wait for regulatory approval,” said Tesla AI director Ashok Elluswamy on the call.

But investors don’t want another Uber. For the business model to work, the human safety monitor needs to be removed from the car. Here as well there was no timetable—just the word “eventually” in the shareholder deck.

The negatives

None of this might be a problem were it not for Tesla’s struggling core car business. With vehicle sales down 13% through the first half, Musk on Wednesday scrapped his guidance but confirmed vehicle sales would definitely grow this year. Now the company says the “actual results will depend on a variety of factors.” Could a second straight year of declines be possible? In October, Musk was still promising a 20% volume increase minimum.

The Tesla CEO also confirmed the low-cost model—effectively a cheaper Model Y—has been delayed. Volume production is now slated for the fourth quarter of this year. Until then, it wants to prioritize meeting demand from customers looking to buy a Tesla before the federal tax credit expires at the start of October.

Starting that same month, however, the outlook begins to darken. “We probably could have a few rough quarters,” Musk conceded, citing Q4, Q1, and potentially Q2 as well. Then the script should flip once its upcoming Cybercab is deployed in sufficiently large numbers in its robotaxi fleet in the latter half of next year financed in part with the $37 billion in cash Tesla holds on its balance sheet.

Fortunately, the upfront costs shouldn’t be too expensive for Tesla to finance. The two-seater was conceived to cut corners on performance, only aiming for a “gentle ride.” Since it’s not really meant for private ownership, it doesn’t need the kind of expensive propulsion system or finely tuned chassis that can deliver the speed, agility, or handling of a typical Tesla.

The positives

There were some positives in the Q2 results. Automotive gross margins, excluding CO2 regulatory credits, came in at 15%, a 40 basis point improvement over last year, giving investors hope the downward trend may finally be forming a bottom.

Nor were the $439 million in regulatory credits needed for the group to earn a profit either, thanks in large part to record profits from its industrial-size Megapack batteries. Sold to utilities for managing sudden peaks in electricity demand, its stationary energy storage solution constitutes a business with gross margins double those of its larger car operations.

Tesla also expanded its Cortex data center in Austin by nearly a third, and now has the equivalent of 67,000 Nvidia H100 AI training chips. Musk also said his company’s own proprietary AI inference chip is built into every Tesla car and will soon become so intelligent it presents a threat to U.S. national security should it end up in the wrong hands.

Referring to his upcoming AI5 chip that follows the current HW4 generation, Musk said: “It’s so powerful we’ll have to nerf it to some degree for markets outside the U.S. because it blows way past the export restrictions.”

But this wasn’t sufficient for the market. True, it is not unusual for the stock to sell off after a business update, since Tesla quarterly calls are often viewed as “buy the rumor, sell the fact” trades.

The news that emerged Wednesday proved, however, lean pickings for shareholders still willing to pay 140 times next year’s consensus earnings to own the stock, especially since the equity story hinges so heavily on the success of its maiden robotaxi fleet.

“Investors were hungry for clear expectations about how many vehicles are on the road in Austin today and what it will end the quarter at,” Deepwater’s Munster added. “They wanted to hear that the company expects the human supervisor to be removed during the quarter or that the service will shift from being invite-only to public availability.”

That hunger was not sated.
