Amazon said revenue in its cloud unit increased 19% in the third quarter, just missing analyst estimates.

Revenue at Amazon Web Services totaled $27.45 billion, according to a statement Thursday, while Wall Street was expecting $27.52 billion, based on StreetAccount estimates. Year-over-year growth has accelerated for five consecutive quarters.

The artificial intelligence portion of AWS is in the billions of dollars in annualized revenue, more than doubling year over year, Amazon CEO Andy Jassy, who previously led AWS, said on a call with analysts.

“I believe we have more demand than we could fulfill if we had even more capacity today,” Jassy said. “I think pretty much everyone today has less capacity than they have demand for, and it’s really primarily chips that are the area where companies could use more supply.”

AWS leads the cloud infrastructure market over Google and Microsoft and is an important source of profit for Amazon.

On Tuesday, Google parent Alphabet said revenue from Google Cloud, which includes cloud applications as well as infrastructure, totaled $11.35 billion, up 35%. Microsoft said Wednesday that revenue from Azure and other cloud services grew 33%.

AWS recorded $10.45 billion in operating income, representing 60% of its parent’s profit. Analysts expected $9.15 billion.

The unit’s operating margin came in at 38%, the widest for AWS since at least 2014. Google Cloud reported an operating margin of 17%.

“We’re being very measured in our hiring,” Brian Olsavsky, Amazon’s finance chief, said on the call.

During the quarter, Oracle said it will bring database services to AWS.

“If this is successful, we would love to find more pieces of their application stack that could run well in AWS and help customers do that,” AWS CEO Matt Garman told CNBC in a September interview.

Also in the quarter, AWS announced plans to discontinue some services, including code-repository tool CodeCommit. Garman told TechCrunch that AWS “can’t invest in everything.”

Intel shares rose 9% in extended trading on Thursday after the chipmaker reported better-than-expected revenue and issued quarterly guidance that topped estimates.

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

• Earnings per share: Loss of 46 cents adjusted
• Revenue: $13.28 billion vs. $13.02 billion expected

Intel’s revenue declined 6% year over year in the quarter, which ended on Sept. 28, according to a statement. The company registered a net loss of $16.99 billion, or $3.88 per share, compared with net earnings of $310 million, or 7 cents per share, in the same quarter a year ago.

As part of its cost reduction plan, Intel recognized $2.8 billion in restructuring charges during the quarter. There were also $15.9 billion in impairment charges.

Intel has been mired in an extended slump due to market share losses in its core businesses and an inability to crack artificial intelligence. CEO Pat Gelsinger revealed plans during the quarter to turn the company’s foundry business into an independent subsidiary, a move that would enable outside funding options.

CNBC reported that Intel had engaged advisors to defend itself against activist investors. In late September, news surfaced that Qualcomm reached out to Intel about a possible takeover.

The Client Computing Group that sells PC chips recorded $7.33 billion in revenue, down about 7% from a year earlier and below the $7.39 billion consensus among analysts surveyed by StreetAccount.

Revenue from the Data Center and AI segment came to $3.35 billion, which was up about 9% and more than the $3.17 billion consensus from StreetAccount.

Intel called for fiscal third-quarter adjusted earnings of 12 cents per share and revenue between $13.3 billion and $14.3 billion. Analysts had expected 8 cents in adjusted earnings per share and $13.66 billion in revenue.

During the quarter, Intel announced the launch of Xeon 6 server processors and Gaudi artificial intelligence accelerators.

As of Thursday’s close, Intel shares were down about 57% in 2024, while the S&P 500 index had gained 20%.

Executives will discuss the results with analysts on a conference call starting at 5 p.m. ET.

Microsoft‘s better-than-expected earnings report wasn’t enough to prevent the stock’s steepest sell-off in two years, as investors instead focused on the company’s forecast for the current period.

Microsoft shares fell 6% on Thursday and headed for their worst day since Oct. 26, 2022, when they dropped 7.7%. That was a month before the public release of ChatGPT from Microsoft-backed OpenAI, a launch that set the stage for a boom in artificial intelligence investments.

For the period ending in December, Microsoft called for revenue in the range of $68.1 billion to $69.1 billion, implying 10.6% growth at the middle of the range. Analysts surveyed by LSEG were looking for $69.83 billion in revenue.

Revenue in Microsoft’s cloud infrastructure business, Azure, increased 33%. CFO Amy Hood said on a call with analysts that growth, in constant currency, will come in at 31% to 32% in the fiscal second quarter.

On Tuesday, Google reported 35% annual growth in its rival cloud business to $11.35 billion. Amazon, which leads the cloud infrastructure market, is scheduled to report results after the close on Thursday.

“We view Q1 results as solid across the core Azure and Office growth businesses, though tempered by a softer Q2 outlook,” analysts at BofA Global Research wrote in a report on Thursday. They still recommend buying the stock.

Fiscal first-quarter revenue increased 16% from a year earlier to $65.59 billion, exceeding the average analyst estimate of $64.51 billion, according to LSEG. Earnings per share of $3.30 topped the $3.10 average estimate.

Net income rose 11% to $24.67 billion from $22.29 billion in the year-ago quarter.

Outside suppliers are late in delivering data center infrastructure to Microsoft, meaning the company won’t be able to meet demand in the fiscal second quarter.

“I feel pretty good that going into the second half of even this fiscal year, that some of that supply-demand will match up,” CEO Satya Nadella said on the earnings call.

Microsoft’s AI investments continue to be a major focus for investors, as the company builds out its infrastructure and ramps up chip spending to handle heftier workloads. Microsoft has invested close to $14 billion in OpenAI, which was valued at $157 billion in a financing round earlier this month.

Hood said on the call she expects the company to take a $1.5 billion hit to income in the current period, mainly because of an expected loss from its investment in the AI startup.

Meanwhile, spending on property and equipment grew 50% year over year to $14.92 billion. The consensus among analysts polled by Capital IQ was $14.58 billion.

As of Thursday’s close, Microsoft shares were up a little over 8% for the year, while the Nasdaq has risen 21% during the same period.
