Tesla Inc. unveiled battery innovations and increased efficiencies that appeared to underwhelm investors late Tuesday at its much anticipated “Battery Day.”
Tesla stock’s TSLA, -5.59%, which had gained more than 4% after an upbeat post-shareholder-meeting presentation, turned south as soon as Chief Executive Elon Musk said that some of the innovations showcased at the event were “close to working.”
Shares were recently down more than 7% in the extended session.
“It does work but not [yet] with a high yield,” Musk said, adding that Tesla has set up a pilot battery plant in Fremont, Calif., to work through the challenges, with production “ramping up.”
There’s a “clear path to success but a ton of work from here to there,” Musk said.
Musk on Monday sought to tamp down Wall Street’s high expectations for the event, tweeting that some of the technologies to be revealed “will not reach serious high-volume production until 2022.”
The stock closed more than 5% lower in Tuesday’s regular trading session.
Tesla set out to completely rethink how cells are produced and designed, Musk, chief executive of not just Tesla but SpaceX, and Tesla’s senior vice president of energy engineering, Drew Baglino, said as they took the stage moments after the conclusion of the shareholder meeting.
It was part presentation, part chemistry lesson, as the two took turns extolling Tesla’s progress toward producing cheaper and more efficient batteries.
The innovations included changes in battery size and in silicon engineering, plans for easier access to lithium, battery recycling, and better integration between battery cell and vehicle. The combined changes would result improvements in range and battery prices.
Tesla shares had gained in the after-hours session during the shareholder-meeting portion of the day’s proceedings, mostly thanks to Musk’s saying that it was looking “promising” that the Silicon Valley car maker would post an annual profit and stay within its previous vehicle-delivery goals for 2020, while vowing to release a more advanced version of Autopilot, the company’s suite of advanced driver-assistance systems, “in a month or so.”
Musk also announced plans for a $25,000 fully autonomous electric vehicle within three years.
Musk called the year “insanely hard” — the hardest ever for Tesla, he said.
The shareholder meeting and “Battery Day” were held outdoors in Fremont due to pandemic-related restrictions on gatherings.
The few shareholders on site were in their Tesla cars, drive-in style, occasionally honking their horns to signal enthusiasm. The shareholder meeting had been postponed from July.
Shares of Tesla have gained 407% so far this year, contrasting with gains of just 2.6% for the S&P 500 index SPX, +1.05%.
