The growth is not the argument

Start with the part that is simply good. AWS grew 39.3% in the third quarter, to $46.0 billion, which Amazon describes as its fastest growth in nearly five years. At that quarterly pace, its revenue annualizes to roughly $184 billion; the figure is a run rate, not a forecast. AWS produced $17.8 billion of the group's $28.1 billion in operating income. The group margin, 13.9%, is the highest Amazon has recorded. Andy Jassy went further than reporting the quarter: he projected AWS revenue growth of over 40% in both 2027 and 2028, and observed that no trillion-dollar revenue business has ever existed and Amazon may have two of them within five to ten years.

The usage numbers underneath are consistent with that confidence, at least in direction. Spending by Fortune 500 companies on Bedrock, Amazon's inference service, rose nearly sevenfold in a year, and Bedrock token volume nearly seventeenfold. AgentCore, its managed service for running agents, counts its customers in the tens of thousands, and those customers deployed twice as many agents in this one quarter as in the previous three combined. "Tens of thousands" is doing considerable work in that sentence. These are Amazon's own usage figures, without an independent check in the material cited here. They suggest growing adoption, but the financial results are the stronger evidence of AWS's commercial performance: revenue reached $46.0 billion and operating income $17.8 billion.

Then read the cash-flow statement

In the same three months, Amazon purchased $77.259 billion of property and equipment, against $35.095 billion a year earlier. Operating cash flow was $42.422 billion, and proceeds from property and equipment sales were $1.381 billion. Applying Amazon's free-cash-flow definition to those quarterly figures gives an outflow of approximately $33.5 billion. That is a calculation from the release's component lines, not a quarterly free-cash-flow figure explicitly stated in the release. Over twelve months, the company directly reported a free-cash-flow outflow of $42.4 billion, against an inflow of $14.8 billion a year earlier.

Amazon states the cause plainly: a $94.8 billion year-over-year increase in net purchases of property and equipment that "primarily reflects investments in artificial intelligence." Trailing-twelve-month operating cash flow rose 29% to $168.3 billion over the same period.

The financing lines show how the gap is being covered. Interest expense in the quarter was $1.69 billion, roughly triple the $538 million of a year earlier, and the company issued $48.1 billion of long-term debt during the quarter. None of this is hidden, but the combination matters: Amazon is investing at a scale that has pushed trailing free cash flow into a substantial outflow, while also issuing significant long-term debt. The figures show the financing burden of the current buildout; they do not, by themselves, establish how much of that investment is funded by debt rather than operating cash or other sources.

Why the headline EPS miss misleads, in both directions

Reported earnings per share fell to $1.89, from $1.95, and missed the $1.97 analysts expected. Taken alone, that suggests deterioration. The release gives the main reason itself: the year-ago quarter included $9.5 billion of pre-tax gains on Amazon's Anthropic investment, and this quarter had no equivalent. Operating income, the cleaner line, rose 61%. Revenue of $201.9 billion missed consensus by roughly $0.4 billion on a base of about $202 billion. Separately, Amazon said Prime Day's shift into the second quarter in most large countries affected the year-over-year comparison: excluding the timing change, reported sales growth would have been about 400 basis points higher. That helps explain the growth comparison, but does not establish how much of the small consensus miss was caused by Prime Day timing.

The honest caution runs the other way as well. A record operating margin and a booming cloud segment do not settle the question investors are actually asking, which is when the spending slows enough for cash to come back. On that, the guidance offers no relief: fourth-quarter sales of $240 to $247 billion and operating income of $28.5 to $33.5 billion, with full-year cash capital spending still expected at about $220 billion. Jassy's answer is growth, specifically AWS above 40% for two more years. That is a testable promise, and it is now the load-bearing one.

The market's first verdict

Shares had already closed down 4% in the regular session, on a day when Alphabet's results were dragging the sector. In after-hours trading GeekWire reported a further fall of more than 7%; TradingKey recorded a drop of over 11% at one point before it narrowed. After-hours moves are thin and provisional, and the conference call, which began at 2:00 p.m. PT, may move the price again. The initial reaction puts the contrast in focus: AWS is growing at 39%, while trailing free cash flow has swung to a $42.4 billion outflow. The results do not establish that this contrast alone drove the after-hours decline, but it is a central question for investors weighing the return on Amazon's continuing infrastructure investment.
