As much as Amazon may have wanted to dodge the spotlight in President Trump’s trade war, there was no avoiding it for America’s largest online retailer.
First, the e-commerce company was entangled in the fleeting spat Tuesday with the White House over a faulty report that Amazon was going to show shoppers the costs of tariffs.
Two days later, the economic reality arrived when Amazon reported among the slowest growth ever in its North American retail business.
The region, Amazon’s largest, contributed to first-quarter financial results that showed the slowest overall sales growth since the depths of the pandemic, the company reported Thursday. Sales from January through March rose to $155.7 billion, 9 percent more than the same period a year earlier. Profit was $17.1 billion, up 64 percent.
For the current quarter, which ends in June, Amazon told investors to expect sales of $159 billion to $164 billion, and for operating profits to shrink to as low as $13 billion. Amazon added “tariff and trade policies” to the list of factors it says can make its forecasts uncertain.
The results were mixed compared with Wall Street’s expectations. Amazon’s stock price was down more than 3 percent in aftermarket trading following the earnings release.
“We’re pleased with the start to 2025, especially our pace of innovation and progress in continuing to improve customer experiences,” Andy Jassy, Amazon’s chief executive, said in a statement.
Investors have been trying to untangle how President Trump’s on-again-off-again tariffs would affect Amazon customers. Some speculated that consumers may have accelerated purchases in March and April ahead of more tariffs kicking in, boosting spending in an otherwise uncertain environment.
“People have not stopped buying, and in certain categories we do see a little bit of people buying ahead,” Mr. Jassy said in a television interview last month.
Many different components drive revenue in Amazon’s retail business. The online sales of products it offers directly to customers grew 5 percent to $57.4 billion, and the services it provides to sellers who list products on its site grew 6 percent to $36.5 billion.
Advertising, which investors view as a promising and profitable business, grew 18 percent to $13.9 billion.
Investors have long focused on Amazon’s cloud computing business, which generates most of the company’s profit. Mr. Jassy, who ran the cloud business before his promotion to chief executive, has been building up the company’s artificial intelligence offerings. The cloud business grew 17 percent, to $29.3 billion, in the first quarter.
The release on Thursday showed Amazon spent more than $24 billion on capital expenses in the first three months of the year, about $2 billion less than the previous quarter.
In February, Mr. Jassy told investors that Amazon did not have enough data centers to meet all the demand it was seeing for cloud computing and artificial intelligence, and said Amazon spent about $100 billion on capital expenditures in 2025.
