Iran’s Islamic Revolutionary Guard Corps (IRGC) has threatened attacks on a swath of U.S. tech companies with operations in the Middle East, including Nvidia, Apple, Microsoft and Google.

The IRGC warned on Tuesday that 18 tech companies would be considered as “legitimate targets” in retaliation for U.S. and Israeli strikes on Iran.

“From now on, for every assassination, an American company will be destroyed,” they said in an IRGC-affiliated Telegram channel.

Attacks on those companies would begin from 8 p.m. on Wednesday, April 1, Tehran time (12:30 p.m. EDT), the IRGC said in a post on Telegram translated by Google, warning employees at those companies to leave workplaces immediately to protect their lives.

The list of companies also featured Cisco, HP, Intel, Oracle, IBM, Dell, Palantir, JP Morgan, Tesla, GE, Spire Solutions, Boeing and UAE-based AI company G42.

It follows Iranian strikes on AWS data centers in the Middle East earlier this month, which caused outages in a number of apps and digital services in the United Arab Emirates.

U.S. tech firms have been funnelling resources into the Middle East in recent years, specifically around the AI infrastructure buildout, with the region offering cheap energy and access to land.

“The safety and wellbeing of our team is our number one priority,” an Intel spokesperson said in a statement to CNBC. “We are taking steps to safeguard and support our workers and facilities in the Middle East and are actively monitoring the situation.”

All the companies listed in the Telegram post have been approached for comment. Microsoft, Google and JP Morgan declined to comment.

U.S.-Israeli strikes on Iran on Feb. 28 prompted retaliatory attacks across the region from Iran.

More than 3,000 drones and missiles have been fired on the United Arab Emirates, Saudi Arabia, Bahrain and Kuwait since the conflict began, according to data compiled by think tank the Center for Strategic and International Studies.

On Tuesday President Donald Trump said he expected that U.S. military forces would leave Iran in “two or three weeks.” The White House announced Trump will address the nation on the Iran war on Wednesday night.

Over 3,400 Iranian civilians and military personnel have been killed during the conflict, according to the Human Rights Activist News Agency (HRANA). Thirteen U.S. service people have been killed, per U.S. Central Command.

Micron’s revenue almost tripled in the latest quarter as results topped analysts’ estimates and guidance sailed past expectations. The stock, which is up more than 350% in the past year, slipped in extended trading.

Here’s how the company did relative to LSEG consensus:

• Earnings per share: $12.20 adjusted vs. $9.31 expected
• Revenue: $23.86 billion vs. $20.07 billion expected

Micron is benefiting from soaring demand for Nvidia graphics processing units that run generative artificial intelligence models. Each generation of Nvidia chip packs in more memory, creating a supply crunch. Micron has been working to add capacity, as have competitors Samsung and SK Hynix.

Revenue in the fiscal second quarter increased from $8.05 billion a year earlier, according to a statement.

For the current period, the company expects about $33.5 billion in revenue, up from $9.3 billion a year ago, implying growth of over 200%. Adjusted earnings per share will be about $19.15, Micron said. Analysts polled by LSEG had expected $12.05 in adjusted earnings per share on $24.3 billion in revenue.

“The step-up in our results and outlook are the outcome of an increase in memory demand driven by AI, structural supply constraints and Micron’s strong execution across the board,” CEO Sanjay Mehrotra said in prepared remarks the company issued at the time of the release.

Micron’s stock has been on a tear. The shares tripled in 2025 and have jumped another 62% year to date as of Wednesday’s close. Among the 10 most valuable U.S. tech companies, Micron is the only one that’s up. Oracle is the leading decliner, down 22%, and Microsoft and Tesla have also seen double-digit percentage drops.

“Looking at how the shares were trading going into this earnings report, I thought the biggest risk was high investor expectations,” said Hendi Susanto, a portfolio manager at Gabelli Funds, in an email. “However, fiscal third-quarter guidance is strong, well above analysts’ and my own expectations.”

Mehrotra said that AI and conventional servers are facing a “lack of adequate DRAM and NAND supply.” That refers to the company’s traditional memory products that have long been used in data centers and devices.

Memory companies have been shifting production capacity largely to high-bandwidth memory, which is embedded onto Nvidia’s latest GPUs and many other chips powering AI. Those products have higher margins.

The company’s GAAP gross margin, the profit left after accounting for the cost of goods sold, more than doubled in the past year to 74.4% from 36.8%, and increased from 56% in the prior quarter.

Net income climbed to $13.8 billion, or $12.07 per share, from $1.58 billion, or $1.41 per share, in the same quarter last year.

Micron said revenue in its cloud memory business rose more than 160% to $7.75 billion. The mobile and client unit saw even steeper growth, with revenue jumping to $7.71 billion from $2.24 billion a year ago.

Memory is typically a commodity business, which comes with lower margins than other silicon products and short-term contracts. In the past few months, memory companies have signed longer-term contracts as semiconductor makers work to ensure future capacity.

“As AI evolves, we expect compute architectures to become more memory-intensive,” the company said in an earnings presentation. “This is why we strongly believe that Micron is one of the biggest beneficiaries and enablers of AI.”

Mehrotra said on the earnings call that volume production of HBM4 for Nvidia’s Vera Rubin started in the fiscal first quarter, and next-generation HBM4e products will ramp in 2027. Nvidia has said it will utilize custom HBM in its next-generation Feynman GPU coming in 2028.

Mehrotra added that capital expenditures will “step up meaningfully” in fiscal 2027, with construction-related costs increasing by over $10 billion.

Micron is building two giant new campuses of fabrication plants in Idaho and New York to increase its memory manufacturing capacity in the U.S. Mehrotra said on the call that initial production at the Idaho site is expected by mid-2027. Micron broke ground in January on the massive $100 billion New York campus, and expects wafer output by the second half of 2028.

AI data center startup Nscale has raised $2 billion at a $14.6 billion valuation, the company announced on Monday, as the AI infrastructure boom continues.

The Series C featured Nvidia and was led by Aker ASA and 8090 Industries. Astra Capital Management, Citadel, Dell, Jane Street, Lenovo, Linden Advisors, Nokia and Point72 also participated.

Nscale is also announcing three new directors on its board, including former Meta COO Sheryl Sandberg, former UK deputy prime minister and Meta executive Nick Clegg and former Yahoo President Susan Decker.

Founded in 2024, Nscale has emerged as a key player in the AI infrastructure buildout, developing data centers and operating cloud computing services.

The UK-based startup has raised a slew of funding in the past year as investors have piled into the sector. It announced a $1.4 billion delayed draw term loan in February and a $1.1 billion Series B in September.

The fresh funds are inclusive of the $433 Million pre-Series C SAFE round in October.

Fresh capital would help accelerate Nscale’s development of vertically integrated AI infrastructure — from GPU compute and networking to data services and orchestration software — across Europe, North America, and Asia, the company said in a statement.

The AI boom is “leading to the largest infrastructure buildout in human history,” said Josh Payne, CEO and founder of UK-based Nscale, echoing past comments from Jensen Huang, CEO at Nvidia, which invested in the round. “We are building this foundation that the market sits on, the engine of superintelligence.”

Nscale is eyeing an initial public offering, the company confirmed to CNBC in October.

The startup, which operates data centers in the U.K., the U.S., Norway, Portugal and Iceland, has inked deals with a number of Big Tech companies in recent times.

Nscale announced an “expanded partnership” with Microsoft in October, netting the younger company $14 billion, a figure first reported by the FT and verified by CNBC. Over the summer, it partnered with OpenAI to launch a Stargate-branded AI data center in Norway.

Nvidia shares dropped 5% on Thursday, as investor concerns around its leadership in the artificial intelligence boom dampened enthusiasm over its earnings beat.

The company reported stellar quarterly results, but the numbers were not enough to assuage Wall Street amid an already fragile time for stocks. Companies across many industries, ranging from trucking to software, have been rattled this year on fears of AI disruption to their businesses. Elevated valuations and high capital expenditures have also set a high bar for these names.

“The debate has shifted away from near-term results and toward the sustainability of AI capex spending, amid concerns around its quantum, monetization and potential cashflow degradation,” Richard Clode, portfolio manager at Janus Henderson, told CNBC.

Nvidia’s decline on the day also pressured several other leading chipmakers. Broadcom shares dropped nearly 6%, while Taiwan Semiconductor Manufacturing dropped more than 3%.

Nvidia’s 10-K regulatory filing published on Wednesday states that while the company is “finalizing an investment and partnership agreement” with the maker of ChatGPT, “There is no assurance that we will enter into an investment and partnership agreement with OpenAI or that a transaction will be completed.”

Tom Graff, chief investment officer at Facet, told CNBC that he expects a “bumpy ride” ahead for the stock for at least the next couple of quarters.

He said that the market expected a good quarter from Nvidia after customers like Microsoft and Amazon projected higher spend on data centers, but investors were seeking more insight from the chip giant.

“What we didn’t get were details about the future guidance,” Graff said. “If players like OpenAI might be slowing spending, that would show up in actual revenue one to two quarters from now, so the lack of specificity about the revenue outlook is generating some concerns.”

To be sure, Gil Luria of D.A. Davidson said that Nvidia provided more detailed guidance for the year than it usually does. He told CNBC that he remains optimistic that the company will be making a large investment in OpenAI despite the “confusing” language in the regulatory filing.

Embattled server maker Super Micro Computer said on Monday that it’s hired BDO as its new auditor and submitted a plan to Nasdaq detailing its efforts to regain compliance with the exchange. The shares jumped 37% in extended trading.

“This is an important next step to bring our financial statements current, an effort we are pursuing with both diligence and urgency,” Super Micro CEO Charles Liang said in a statement.

Super Micro is late in filing its 2024 year-end report with the SEC, and said earlier this month that it was looking for a new accountant after its previous auditor, Ernst & Young, stepped down in October. Ernst & Young was new to the job, having just replaced Deloitte & Touche as Super Micro’s accounting firm in March 2023.

Super Micro said it told Nasdaq that it believes it will be able to file its annual report for the year ended June 30, and quarterly report for the period ended Sept. 30. The company said it will remain listed on the Nasdaq pending the exchange’s “review of the compliance plan.”

Shares of Super Micro soared more than twentyfold over a two year period from early 2022 until their peak in March of this year. But the stock has been hammered on troubling news about its compliance with Nasdaq. Once valued at about $70 billion, the company’s market cap was at $12.6 billion at the close on Monday, following a 16% rally during regular trading.

Super Micro has been one of the primary beneficiaries of the artificial intelligence boom, due to its relationship with Nvidia. Sales last fiscal year more than doubled to $15 billion.

On Monday, Super Micro announced that it was selling products featuring Nvidia’s next-generation AI chip called Blackwell. The company competes with vendors like Dell and Hewlett Packard Enterprise in packaging up Nvidia AI chips for other companies to access.

Super Micro was added to the S&P 500 in March, reflecting its rapidly growing business and then-soaring stock price. Less than two weeks after the index changes were announced, Super Micro reached its closing high of $118.81.

The troubles began within months. In August, Super Micro said it wouldn’t file its annual report with the SEC on time. Noted short seller Hindenburg Research then disclosed a short position in the company, and said in a report that it identified “fresh evidence of accounting manipulation.” The Wall Street Journal later reported that the Department of Justice was at the early stages of a probe into the company.

The month after announcing its report delay, Super Micro said it had received a notification from the Nasdaq, indicating that the delay in the filing of its annual report meant the company wasn’t in compliance with the exchange’s listing rules. Super Micro said the Nasdaq’s rules allowed the company 60 days to file its report or submit a plan to regain compliance. Based on that timeframe, the deadline was Monday.

Cisco reported a fourth straight quarter of declining revenue even as results topped analysts’ estimates. The stock slipped 2.5% in extended trading.

Here’s how the company did in comparison with LSEG consensus:

• Earnings per share: 91 cents adjusted vs. 87 cents expected
• Revenue: $13.84 billion vs. $13.77 billion expected

Cisco’s revenue dropped 6% in the quarter ended Oct. 26, from $14.7 billion a year earlier, according to a statement. Net income fell to $2.71 billion, or 68 cents per share, from $3.64 billion, or 89 cents per share, in the same quarter a year ago.

Networking revenue plunged 23% to $6.75 billion, slightly below the $6.8 billion consensus of analysts surveyed by StreetAccount.

Security revenue doubled to $2.02 billion, topping the StreetAccount consensus of $1.93 billion. Cisco’s revenue from collaboration was $1.09 billion, a bit below the $1.04 billion consensus estimate.

Cisco CEO Chuck Robbins said on the earnings call on Wednesday that orders from large-scale clients for artificial intelligence infrastructure exceeded $300 million in the quarter. Server makers such as Dell and HPE have also focused on sales of hardware that can help clients implement generative AI.

“We have earned more design wins and remain confident that we will exceed our target of $1 billion of AI orders this fiscal year from web-scale customers,” Robbins said.

Cisco has announced hardware containing Nvidia’s graphics processing units, which are widely used for training AI models, Robbins said.

“Over time, you’ll see us support other GPUs as the market demands,” he said. “But that partnership is still going fine. It’s still early. And I think 2025 is when we’ll start to see enterprise real deployment of some of these technologies.”

For now, enterprises are updating data center infrastructure to prepare for AI and the widespread deployment of AI applications, Robbins said.

U.S. government agencies have delayed deals with Cisco, rather than scrapping them altogether. The Fiscal Responsibility Act of 2023, which became law in June of last year, has limited U.S. government spending, said Scott Herren, Cisco’s finance chief.

Herren said that with Republicans poised to control the White House and both houses of Congress, he expects “to get a budget in place relatively soon.”

During the quarter, Cisco acquired security startups DeepFactor and Robust Intelligence.

Cisco lifted its full-year guidance to $3.60 to $3.66 in adjusted earnings per share on $55.3 billion to $56.3 billion in revenue, up from a prior forecast of $3.52 to $3.58 in EPS and $55 billion to $56.2 billion in revenue. Guidance would indicate projected revenue growth of 3.3% at the middle of the range.

Analysts expected adjusted earnings for the year of $3.58 per share on $55.89 billion in revenue.

As of Wednesday’s close, Cisco’s stock was up 17% year to date, while the S&P 500 index is up around 26% over that stretch.

Super Micro Computer could be headed down a path to getting kicked off the Nasdaq as soon as Monday.

That’s the potential fate for the server company if it fails to file a viable plan for becoming compliant with Nasdaq regulations. Super Micro is late in filing its 2024 year-end report with the SEC, and has yet to replace its accounting firm. Many investors were expecting clarity from Super Micro when the company reported preliminary quarterly results last week. But they didn’t get it.

The primary component of that plan is how and when Super Micro will file its 2024 year-end report with the Securities and Exchange Commission, and why it was late. That report is something many expected would be filed alongside the company’s June fourth-quarter earnings but was not.  

The Nasdaq delisting process represents a crossroads for Super Micro, which has been one of the primary beneficiaries of the artificial intelligence boom due to its longstanding relationship with Nvidia and surging demand for the chipmaker’s graphics processing units. 

The one-time AI darling is reeling after a stretch of bad news. After Super Micro failed to file its annual report over the summer, activist short seller Hindenburg Research targeted the company in August, alleging accounting fraud and export control issues. The company’s auditor, Ernst & Young, stepped down in October, and Super Micro said last week that it was still trying to find a new one.

The stock is getting hammered. After the shares soared more than 14-fold from the end of 2022 to their peak in March of this year, they’ve since plummeted by 85%. Super Micro’s stock is now equal to where it was trading in May 2022, after falling another 11% on Thursday.

Getting delisted from the Nasdaq could be next if Super Micro doesn’t file a compliance plan by the Monday deadline or if the exchange rejects the company’s submission. Super Micro could also get an extension from the Nasdaq, giving it months to come into compliance. The company said Thursday that it would provide a plan to the Nasdaq in time. 

A spokesperson told CNBC the company “intends to take all necessary steps to achieve compliance with the Nasdaq continued listing requirements as soon as possible.”

While the delisting issue mainly affects the stock, it could also hurt Super Micro’s reputation and standing with its customers, who may prefer to simply avoid the drama and buy AI servers from rivals such as Dell or HPE.

“Given that Super Micro’s accounting concerns have become more acute since Super Micro’s quarter ended, its weakness could ultimately benefit Dell more in the coming quarter,” Bernstein analyst Toni Sacconaghi wrote in a note this week.

A representative for the Nasdaq said the exchange doesn’t comment on the delisting process for individual companies, but the rules suggest the process could take about a year before a final decision.
