Amazon posts record operating profit but misses on earnings as AI spending burns cash

Amazon.com reported record quarterly operating profit on Thursday, but the results were overshadowed by a sharp swing into negative free cash flow and fourth-quarter guidance that fell short of Wall Street's targets, sending shares lower in after-hours trading. The results, covering the three months ended September 30, were disclosed in a filing with the Securities and Exchange Commission after markets closed.

The quarter captured a tension that has come to define Big Tech's earnings season this year: cloud computing and artificial intelligence demand are accelerating, but the capital spending required to meet that demand is consuming cash faster than investors expected. Amazon shares, which had already fallen 4.25 percent during the regular session, extended their decline after the report, with several trading desks putting the after-hours drop at somewhere between 5 and 9 percent depending on the moment measured.

The numbers

Net sales rose 12 percent from a year earlier to $201.9 billion, according to the earnings release filed as an exhibit to the 8-K, narrowly below the roughly $202.2 billion to $202.3 billion analysts had expected and at the upper end of the company's own guidance range. Diluted earnings per share came in at $1.89, short of the consensus estimate of roughly $1.96 to $1.97, even though operating income of $28.1 billion — up from $17.4 billion a year earlier, and a 13.9 percent margin the company called its highest ever — topped the high end of the range Amazon itself had forecast three months ago.

Amazon Web Services, the company's cloud division, remained the standout. AWS revenue climbed 39 percent year over year to $46.0 billion, its fastest growth in nearly five years, and segment operating income rose to $17.8 billion from $11.4 billion. North America retail sales grew 6 percent to $112.9 billion and International sales grew 5 percent to $43.1 billion, both posting improved operating margins.

Net income nonetheless fell to $20.7 billion, or $1.89 a share, from $21.2 billion, or $1.95 a share, a year ago. According to the company's own account of the results, the decline reflects a difficult comparison: a year earlier, Amazon had booked a one-time $9.5 billion pre-tax gain from a markup on its investment in the AI startup Anthropic, a gain that did not repeat this quarter.

A widening cash gap

The more consequential number for investors was cash flow. Trailing-twelve-month operating cash flow rose 29 percent to $168.3 billion, but free cash flow swung to an outflow of $42.4 billion, compared with a $14.8 billion inflow over the same period a year earlier. Amazon attributed the reversal chiefly to a $94.8 billion year-over-year increase in purchases of property and equipment, almost entirely tied to data centers, chips and other infrastructure for artificial intelligence and cloud computing. The company said it still expects roughly $220 billion in cash capital expenditures for 2026 as a whole, unchanged from prior guidance.

That spending pace puts Amazon alongside Microsoft, Alphabet and Meta Platforms, which have all disclosed tens of billions of dollars in AI-related capital spending this earnings season, in a wager that current infrastructure outlays will be repaid by future cloud and AI revenue. Chief executive Andy Jassy framed the bet in sweeping terms on the earnings call, arguing that Amazon's cloud and retail businesses are each approaching unprecedented scale.

"There has never been a trillion dollar revenue business, and we may have two of them in the next five to ten years," Jassy told analysts, according to the company's earnings materials.

He also pointed to the AWS acceleration as evidence the spending is already paying off: "Our AWS investment in functionality and infrastructure is working, with over 39 percent year-over-year revenue growth in Q3."

Who is watching, and why

The results matter well beyond Amazon's own shareholders. The company is one of the largest employers in the United States and one of the three dominant cloud providers, alongside Microsoft's Azure and Google Cloud, that corporations and government agencies rely on for computing infrastructure; AWS's growth rate is read across the technology sector as a proxy for overall enterprise AI adoption. Retailers and logistics companies that compete with or depend on Amazon's marketplace watch its North America segment margins closely, and chipmakers and data-center landlords have a direct stake in whether Amazon's capital spending plans hold or expand. Index funds tracking the S&P 500 and Nasdaq Composite also carry significant exposure to Amazon, one of the handful of companies whose earnings can move those benchmarks on a single day; both indexes fell the day of the report, with the Nasdaq Composite down 1.38 percent and the S&P 500 down 0.31 percent, as other large technology stocks also traded lower.

Reaction on Wall Street split along familiar lines. Coverage from The Motley Fool's market wrap noted that investors fixated on the capital-expenditure figure and the cash-flow swing even as AWS beat growth expectations, while a report from Deadline placed the selloff in the context of a broader pullback across large technology stocks this week. Bulls pointed to AWS's accelerating growth and management's statement that it expects cloud growth to stay above 40 percent in 2027 and 2028 as evidence the spending will eventually convert to profit; skeptics focused on the size of the cash outflow and asked how long investors should tolerate negative free cash flow at a company of Amazon's scale.

What comes next

Amazon guided to fourth-quarter net sales of $240 billion to $247 billion, representing 12 to 16 percent growth, a range whose midpoint sits slightly below the roughly $244.3 billion to $244.5 billion analysts had modeled. The company guided operating income for the quarter to $28.5 billion to $33.5 billion, well above the $25.0 billion it reported in the fourth quarter of 2025. That guidance covers the holiday shopping season, Amazon's largest sales period of the year, and will be the first full quarter to show whether AWS's growth streak and the North America segment's improved margins can continue alongside the heaviest capital spending in the company's history.

Investors will get more evidence of how the broader AI-spending wager is playing out as Microsoft, Alphabet and Meta finish reporting their own results this earnings season, and as Amazon itself reports fourth-quarter results early next year — the first quarter in which the full-year $220 billion capital-spending figure will be tested against actual results. Until then, the gap between Amazon's record operating profit and its negative free cash flow is likely to remain the central question hanging over the stock.
