The National Highway Traffic Safety Administration is pressing Tesla for answers about changes the company made to its Autopilot driver assistance system following a voluntary software recall in December that affected about 2 million vehicles in the U.S.

Tesla must meet a deadline of July 1 to provide information to the regulator or face fines up to $135.8 million, according to a letter sent by the NHTSA to company on May 6.

The recall was intended to improve Tesla’s driver-engagement systems, which are used to monitor whether drivers are safely using features like traffic aware cruise control, lane keeping and auto steering — part of Autopilot. Since the recall, at least 20 Tesla vehicles have been involved in crashes in which the system was thought to be in use, according to a filing on the NHTSA’s website.

The “recall remedy” probe follows a three-year investigation by the agency that found safety issues with Tesla Autopilot contributed to at least 467 collisions and 14 deaths from January 2018 through August 2023.

The NHTSA had concluded that drivers involved in those crashes “were not sufficiently engaged in the driving task and that the warnings provided by Autopilot when Autosteer was engaged did not adequately ensure that drivers maintained their attention on the driving task.”

Driver-engagement systems, sometimes known as driver-monitoring systems, in Tesla vehicles include torque sensors in the steering wheel to detect whether drivers are keeping their hands on the wheel, and in-cabin cameras that monitor a driver’s gaze. They should alert any inattentive driver to pay attention and stay ready to steer or brake at any time.

The NHTSA is seeking detailed crash data from the electric vehicle maker since the agency issued the recall update on Autopilot, including data and video stored in or streamed from its cars and retained by the company.

They’re also asking for records about Tesla’s engineering teams and their approach to “safety defect determination decision making,” “issue investigation,” “action design including human factors considerations (initial and modifications),” and “testing.”

Tesla is in the middle of a massive reorganization and sweeping layoffs. The company hasn’t disclosed how many jobs in its Autopilot and vehicle-safety engineering teams may have been cut.

For about a decade, CEO Elon Musk has been promising that Tesla is on the cusp of a self-driving breakthrough. With sales of Tesla EVs dropping in the first quarter, Musk has been focusing investors’ attention on his dream of a future full of Tesla artificial intelligence products, including robotaxis and “sentient” humanoid robots that can do factory work.

Tesla shares fell 3.8% on Tuesday to $177.81 and are down 28% year to date.

Reddit shares rallied 14% in extended trading on Tuesday after the company released quarterly results for the first time since its IPO in March.

Here’s how the company did:

• Loss per share: $8.19 loss per share. That may not compare with the $8.71 loss expected by LSEG
• Revenue: $243 million vs. $212.8 million expected by LSEG

Revenue climbed 48% from $163.7 million a year earlier. The company reported $222.7 million in ad revenue for the period, up 39% year over year, which is a faster rate of growth than at its top competitors.

Digital advertising companies have started growing again at a healthy clip after brands reeled in spending to cope with inflation in 2022. Meta‘s ad revenue jumped 27% in the first quarter, followed by 24% growth at Amazon and 13% growth at Google parent Alphabet.

Reddit reported a net loss of $575.1 million. Stock-based compensation expenses and related taxes were $595.5 million, primarily driven by IPO charges.

For the second quarter, Reddit expects revenue of $240 million to $255 million, topping the $224 million expected by analysts, according to LSEG. The midpoint of the guidance range suggests growth of about 32% for the second quarter, up from $183 million from a year earlier.

Reddit, which hosts millions of online forums on its platform, was founded in 2005 by Alexis Ohanian and Steve Huffman, the company’s CEO. 

“We see this as the beginning of a new chapter as we work towards building the next generation of Reddit,” Huffman said in a release Tuesday.

Reddit began trading under the ticker symbol “RDDT” on the New York Stock Exchange in March. The company priced its IPO at $34 per share, which valued the company around $6.5 billion. When tech valuations were red hot in 2021, Reddit’s private market valuation reached $10 billion.

The stock climbed past $58 in after-hours trading on Tuesday before coming back a bit. Should the stock close above $57.75 on Wednesday, it would be at its highest since March 26, its fourth day of trading. The shares closed that day at $65.11, their highest yet.

The company reported 82.7 million daily active users for its first quarter, up from the 76.6 million expected by StreetAccount. Average revenue per user worldwide rose 8% to $2.94 from $2.72 a year ago.

Reddit will hold its first quarterly call with investors at 5 p.m. ET.

WATCH: Reddit shares climb after earnings

Tesla Chairwoman Robyn Denholm has just sold $17.3 million worth of her shares in the electric vehicle maker, according to a filing Monday, bringing her total stock sales this year to more than $50 million.

Denholm, who joined Tesla’s board as an independent director in 2014 and became chair four years later, sold the shares as part of what’s called a 10b5-1 program put into place in October. She has now sold all of the 281,116 shares allowed in the agreement.

While Denholm still has the vast majority of the 1.66 million shares she owned as of the end of last year, according to the company’s proxy filing, her stock sales follow hefty selling from other big stakeholders. Former Tesla Senior Vice President Drew Baglino, who announced his resignation in mid-April, sold shares worth around $181.5 million soon after his departure, according to a filing.

Another Tesla board member, Kathleen Wilson-Thompson, set up a 10b5-1 trading plan in February 2024, for the potential sale of up to 280,000 shares by or before Feb. 28, 2025.

Tesla shares are down 26% this year, closing Monday at $184.76. The slide comes as the company faces increased competition, weakened demand for its EVs and a drop in first-quarter deliveries.

CEO Elon Musk has tried to focus investors’ attention on the company’s self-driving future instead of its core automotive business. He told investors on Tesla’s earnings call last month that those who doubt the company’s ability to deliver self-driving vehicles should stay away from the stock. For years, Tesla has been working to develop, but hasn’t brought to market, software that will make its existing cars autonomous, a dedicated robotaxi and humanoid robots capable of factory work.

“If somebody doesn’t believe Tesla’s going to solve autonomy, I think they should not be an investor in the company,” Musk said on the call.

In Denholm’s early years on the Tesla board, she served on the audit committee. She eventually replaced Musk as chair in November 2018, after the company struck an agreement with the SEC to settle civil securities fraud charges requiring Musk to relinquish that role temporarily, among other provisions.

The SEC had charged Musk and Tesla with securities fraud after Musk said, in a series of tweets in 2018 that he was considering taking the company private at $420 per share with “funding secured.” The tweets led to a stretch of volatility in Tesla shares.

Before joining the Tesla board, Denholm served in executive roles at Sun Microsystems, and in finance roles at Toyota in Australia and at accounting firm Arthur Andersen. Denholm is currently part of Tesla’s audit, compensation, nominating and corporate governance, and disclosure controls committees.

Denholm, who didn’t respond to a request for comment, is a named defendant in a shareholder lawsuit — Tornetta vs. Musk — that was decided in January. The judge in the Delaware case ruled that Tesla’s 2018 CEO pay plan, which was the largest in public corporate history, was only allowed by a board that was “beholden to Musk,” and should be rescinded.

In her opinion, Chancellor Kathaleen McCormick wrote that by serving on Tesla’s board, Denholm received “life-changing” compensation, which “far exceeded the compensation she received from other sources.”

Denholm’s latest stock sales coincide with struggles at Tesla and a broad restructuring effort that’s included thousands of layoffs.

Demand for Tesla’s EVs slumped in the first quarter, and inventory levels have visibly swelled. Revenue in the period fell 9% from a year earlier, the steepest drop since 2012, while net income plunged 55%.

Musk said in an internal memo in April that Tesla was cutting more than 10% of its global headcount. He didn’t say which departments or locations would be most affected. In the earnings call, he referred to the restructuring as a “pruning exercise” and added, “We’re not giving up anything that is significant that I’m aware of.” He said that if the company organizationally is “5% wrong per year,” its cumulative inefficiency comes out to 25% or 30%.

Denholm and Musk are currently trying to convince shareholders to vote with directors and executives at Tesla on a number of proxy proposals.

The most material proposal asks shareholders to return to Musk his compensation package that was invalidated by the Delaware Chancery Court in the Tornetta decision. The pay package would be worth tens of billions of dollars in Tesla shares to Musk.

Tesla’s largest individual retail shareholder, tech billionaire Leo Koguan, has repeatedly called for investors to vote against the plan. In a post on X, Koguan recently wrote, “Don’t be a sucker, just vote NO.”
