Amazon shares jump as cloud, advertising units drive revenue beat

Amazon shares rose as much as 10% in extended trading on Thursday after the e-retailer reported first-quarter revenue that topped analysts' estimates.

Here are the key numbers:

Earnings: 31 cents per shareRevenue: $127.4 billion vs $124.5 billion expected, according to analysts surveyed by Refinitiv

Here's how other key Amazon segments did during the quarter:

Amazon Web Services: $21.3 billion vs. $21.22 billion expected, according to StreetAccountAdvertising: $9.5 billion vs. $9.1 billion, according to StreetAccount

It is not immediately clear if the reported earnings are comparable to the Refinitiv analyst estimate of 21 cents per share.

For the second quarter, Amazon said revenue will be $127 billion to $133 billion. Analysts had called for sales of $129.8 billion, according to Refinitiv.

"Our advertising business continues to deliver robust growth, largely due to our ongoing machine learning investments that help customers see relevant information when they engage with us, which in turn delivers unusually strong results for brands," CEO Andy Jassy said in the earnings statement.

Jassy said that while AWS continues to navigate more cautious spending from cloud customers, he believes "there's much growth ahead," pointing to the company's investments in large language models.

Revenue increased 9% from $116.4 billion a year earlier. While the figure exceeded expectations, Amazon remains mired in single-digit sales growth coming off its weakest year for expansion in its quarter-century as a public company.

The second-quarter forecasts suggests Amazon expects sales to rise between 5% and 10% from the same period a year earlier.

Prior to the after-hours rally, Amazon shares were up 31% for the year after losing roughly half their value in 2022.
