Alphabet-owned Waymo and Toyota on Tuesday announced a preliminary partnership to explore bringing robotaxi tech to personally-owned vehicles.

“The companies will explore how to leverage Waymo’s autonomous technology and Toyota’s vehicle expertise to enhance next-generation personally owned vehicles,” the two companies announced.

The companies said they aim to use the partnership to more quickly develop driver assistance and autonomous vehicle technologies for personal vehicles. Toyota is the world’s largest automaker by sales. 

Waymo co-CEO Tekedra Mawakana said the strategic partnership could also result in the Google-owned company incorporating Toyota’s “vehicles into our ride-hailing fleet.”

The Toyota tie-up is the latest automotive partnership for Waymo.

The self-driving company has previously worked with automakers such as Jaguar Land Rover, Stellantis predecessor Fiat Chrysler, Daimler Trucks, Mercedes-Benz parent Daimler, Hyundai Motor and China’s Geely Zeekr. The partnerships, many of which touted long-term tie-ups, largely resulted in automakers producing modified vehicles for testing or for Waymo to use in its fleets.

The partnership with Toyota will not affect Waymo’s plans to deploy Hyundai and Zeekr vehicles through the Waymo One service in the future, a spokesman for the Alphabet-owned company told CNBC.

Waymo is now serving 250,000 paid rides per week, up from 200,000 in February, before Waymo opened in Austin and expanded in the San Francisco Bay Area in March. Waymo is already running its commercial, driverless ride-hailing services in the San Francisco, Los Angeles, Phoenix and Austin regions.

Alphabet CEO Sundar Pichai noted in first-quarter earnings last week that Waymo has not entirely defined its long-term business model, and there is “future optionality around personal ownership” of vehicles equipped with Waymo’s self-driving technology.

Waymo and Toyota are not the only companies turning their focus to personally-owned autonomous vehicles. When GM announced in December that it was abandoning its Cruise robotaxi business, the company said it would instead focus on the development of autonomous systems for use in personal vehicles.

Toyota previously invested in and partnered with Tesla, Elon Musk’s automaker which now aims to compete with Waymo on driverless tech. Toyota sold the its stake in the EV maker in June 2017.

Tesla, once seen as a pioneer in self-driving tech, does not yet produce cars that are safe to use without a human driver at the wheel, ready to steer or brake at any time.

Elon Musk, Tesla CEO, criticized Waymo on a recent earnings call claiming the robotaxis are too expensive for mass-production. Musk also promised Tesla will be “selling fully autonomous rides in June in Austin,” using Model Y vehicles with a new “unsupervised” version of the company’s “Full Self-Driving” or FSD systems installed.

Super Micro shares fell as much as 19% on Tuesday after the server maker announced preliminary results for the fiscal third quarter that were lower than analysts had projected.

Here’s how the company’s preliminary numbers compare with the LSEG consensus:

• Earnings per share: 29 to 31 cents per share adjusted vs. 54 cents expected
• Revenue: $4.5 billion to $4.6 billion vs. $5.50 billion expected

Super Micro lowered the ranges from earlier guidance for the quarter, which ended on March 31, according to a statement. The new revenue range implies 18% growth year over year. That’s a large step down from the 200% growth Super Micro delivered a year ago.

“During Q3 some delayed customer platform decisions moved sales into Q4,” the company said in the statement. In addition, the company faced higher inventories from older products, as well as expedite fees. The two factors narrowed Super Micro’s preliminary gross margin by 220 points from the prior quarter.

Shares of server competitor Dell were down almost 5% in after-hours trading, while Hewlett Packard Enterprise was down about 2%. Nvidia shares also fell roughly 2%.

The pre-announcement is the latest blow for Super Micro, which has been mired in controversy for the past year due to delayed financial filings and troubling reports from short sellers. In February, the company filed its financials for its fiscal 2024 year and the first two quarters of fiscal 2025 just in time to meet Nasdaq’s deadline to stay listed. Last year, after Super Micro delayed its annual report, it lost its auditor, Ernst & Young, citing governance issues.

After more than tripling in 2023, thanks to the company’s position in the AI boom and its sales of servers packed with Nvidia’s processors, Super Micro shares plummeted in the second third and fourth quarters last year, wiping out more than 80% of its market cap.

“We have confidence that our calendar year 2025 growth could be a repeat of calendar year 2023, if not better, assuming the supply chain can keep pace with demand,” Charles Liang, Super Micro’s CEO, told analysts on a conference call in February.

Prior to Tuesday’s announcement, the stock was up 18% in 2025, rallying as the broader tech market was in decline.

Super Micro will go over the results with analysts on a conference call at 5 p.m. ET on Tuesday, May 6.

Snap reported better-than-expected first-quarter revenue Tuesday but declined to provide guidance, citing macroeconomic uncertainties that could weigh on advertising demand.

Shares dropped 13% in after-hours trading.

Here is how the company did compared with Wall Street’s expectations:

• Earnings per share: Loss of 8 cents. That figure is not comparable to analysts’ estimates.
• Revenue: $1.36 billion vs. $1.35 billion expected, according to LSEG 
• Global daily active users: 460 million vs. 459 million expected, according to StreetAccount
• Global average revenue per user: $2.96 vs. $2.93 expected, according to StreetAccount

Snap did not offer an outlook for the second quarter, citing uncertainties surrounding “how macro economic conditions may evolve in the months ahead, and how this may impact advertising demand more broadly.”

Analysts had expected $1.39 billion in second-quarter revenue guidance. The company said it expects daily active users to come in near the midpoint of its second-quarter range at 468 million.

“While our topline revenue has continued to grow, we have experienced headwinds to start the current quarter, and we believe it is prudent to continue to balance our level of investment with realized revenue growth,” the company said in a letter to investors.

Like many tech companies, Snap is facing a turbulent macro setup as it grapples with President Donald Trump’s evolving trade plans. Many fear that global trade uncertainty might lead companies to lower guidance or pull back spending this earnings season.

Snap’s cited potential constraints on advertising demand as the reason for holding off on guidance. Ad revenues for the period rose 9% year over year to $1.21 billion. That growth came mainly from direct response advertising. The company also said that brand-oriented advertising revenue dipped 3% from a year ago.

The company isn’t alone. Last Thursday, Alphabet reported first-quarter sales of $90.23 billion, which surpassed Wall Street expectations, but executives told analysts that the company may experience headwinds to its online ad business in the Asia-Pacific region.

Snap lowered its full-year adjusted operating expenses range to between $2.65 billion and $2.70 billion, down from $2.70 billion to $2.75 billion. The company also revised its full-year cost guidance for stock based compensation downward to between $1.13 billion and $1.16 billion from $1.15 billion to $1.20 billion.

Sales in Snap’s first quarter jumped 14% to $1.36 billion from $1.19 billion in the year-ago period. The company reported a net loss of about $140 million, or 8 cents per share. That narrowed 54% from about $305 million, or 19 cents, in the year-ago period. Adjusted EBITDA came in at $108 million, topping a $64 million estimate from StreetAccount.

The company attributed the 8 cents loss to a $70.1 million charge related to cash severance, stock-based compensation expenses and other costs associated with a 2024 restructuring. “These charges are not reflective of underlying trends in our business,” the company said.

Snap posted 460 million daily active users during the period, up from 453 million the previous quarter. The company also said that it reached 900 million monthly active users, up from 850 million in August, the last time Snap provided that stat.
