Takeaway
Amazon posted its fastest AWS growth in nearly five years and its highest operating margin ever, and the stock was still sold hard after the bell. The market is weighing a diluted EPS of $1.89 and a trailing free-cash-flow outflow of $42.4 billion, which the company ties to AI investment, against the cloud acceleration. AMZN was quoted at $222.12, down 8.89%, in after-hours trading at 4:20 PM ET.
What happened (source + time ET)
Amazon released third-quarter results after the close on Thursday, October 29, 2026 (company release, Business Wire; Benzinga coverage timestamped 4:20 PM ET). Figures from the release:
- Net sales rose 12% to $201.9 billion, versus $180.2 billion a year earlier. Excluding a $0.9 billion foreign-exchange headwind, growth was 13%. Amazon said Prime Day timing moved into Q2 this year for most large countries; excluding that shift, Q3 growth would have been about 400 basis points higher.
- North America sales rose 6% to $112.9 billion. International sales rose 5% to $43.1 billion (8% ex-FX).
- AWS sales rose 39% to $46.0 billion, the fastest growth in nearly five years, which Amazon described as a $184 billion annualized run rate.
- Operating income was $28.1 billion versus $17.4 billion a year earlier, a 13.9% margin that Amazon called its highest ever. AWS operating income was $17.8 billion versus $11.4 billion.
- Net income was $20.7 billion, or $1.89 per diluted share, versus $21.2 billion, or $1.95, a year earlier. Amazon attributed the decline mainly to $9.5 billion of pre-tax gains from its Anthropic investments that were booked in Q3 2025.
- Trailing-twelve-month operating cash flow rose 29% to $168.3 billion. Trailing free cash flow swung to an outflow of $42.4 billion, driven by a $94.8 billion year-over-year increase in property and equipment purchases that Amazon said mainly reflects AI investment.
Benzinga headlined the print a "double miss" with accelerating AWS growth. A separate report (ShiftDelete) cites a $1.96 LSEG EPS consensus, a roughly $220 billion 2026 capex plan, and Q4 net sales guidance of $240.0 to $247.0 billion with operating income of $28.5 to $33.5 billion. Those three items were not in the portion of the release we could retrieve, so treat them as reported by that outlet.
Mag7 impact (with tape numbers)
AMZN is the direct name. After-hours, Benzinga showed AMZN at $222.12, down 8.89%, and ShiftDelete described a fall of more than 8%. Both are extended-hours quotes, not a closing print, and thin after-hours liquidity can move a stock quickly in either direction.
The read-through to the AI-infrastructure group is the AWS number: cloud demand is accelerating, but so is the cash cost of serving it. Alphabet and Microsoft, which reported Wednesday, faced the same question of whether growth justifies the spend. Alphabet's shares fell sharply after its report, and Microsoft's reaction was milder, so the group has been splitting on how the market scores capex against growth. Amazon's print adds another data point on the cost side of that trade.
Tape / technicals
- AMZN: after-hours $222.12, −8.89% (Benzinga, 4:20 PM ET). The prior regular-session close could not be verified, so no session change is shown.
- RSI, trend vs EMA20, relative volume, implied volatility and performance versus SPY were not available from a verified source this hour (BudFox's fresh tape is paywalled and the older tape returned no rows). They are omitted rather than estimated.
Tape source: public quotes (price/move only; no technicals).
Desk read
- AMZN — Neutral (Confidence: Medium). AWS growth of 39% and a record 13.9% operating margin support the business, while the $42.4 billion free-cash-flow outflow and EPS of $1.89, down from $1.95, give the market a reason to question the payoff on AI spending. The two effects roughly offset in the fundamentals, and the after-hours move shows the market currently weighting the cash outflow more heavily.
What would change this view: AWS growth holding near 39% on the earnings call while management gives a clearer path for capital spending to convert into free cash flow.
What to watch
- Management's earnings-call commentary on 2026 capital spending, AWS capacity constraints and the timing of free-cash-flow recovery.
- Where AMZN opens Friday versus the after-hours quote, since extended-hours moves often change once regular trading begins.
- Whether the Alphabet and Microsoft pattern, where growth is rewarded or punished depending on spend, extends across other AI-infrastructure names.
- The Prime Day timing shift: Q3 comparisons are depressed by it, so the Q4 read matters for judging underlying retail growth.

FAQ
Q&A · 10
Grounded in this note
Q1 What was the primary driver of Amazon's stock decline despite strong AWS growth?
The stock was negatively impacted by a diluted EPS of $1.89 and a significant trailing free-cash-flow outflow of $42.4 billion. The market is weighing these financial metrics against the accelerated cloud growth.
Q2 How did AWS perform in the third quarter?
AWS sales grew 39% to $46.0 billion, marking the fastest growth in nearly five years. Amazon also reported a record operating margin of 13.9% for the company overall, with AWS contributing $17.8 billion in operating income.
Q3 What is the significance of the $42.4 billion free-cash-flow outflow?
This represents a swing to an outflow for trailing free cash flow, driven by a $94.8 billion year-over-year increase in property and equipment purchases. Amazon attributes this spending primarily to AI investment.
Q4 How did Amazon's net income and EPS compare to the prior year?
Net income was $20.7 billion, or $1.89 per diluted share, down from $21.2 billion, or $1.95, a year earlier. The decline in net income was mainly attributed to pre-tax gains from Anthropic investments booked in the prior year's Q3.
Q5 What is the 'Mag7 impact' discussed in the note?
The note discusses how Amazon's results add to the market's evaluation of AI infrastructure companies like Alphabet and Microsoft. It highlights the ongoing question of whether accelerated growth justifies increased capital expenditure and cash costs.
Q6 What does the note mean by 'double miss'?
The term 'double miss' refers to Amazon's Q3 results being considered a miss on both earnings per share (EPS) and potentially free cash flow, despite accelerating AWS growth. This indicates the market focused on the financial outflows over the revenue acceleration.
Q7 How did the timing of Prime Day affect reported sales growth?
Amazon stated that Prime Day timing moved into Q2 for most large countries this year. Excluding this shift, Q3 net sales growth would have been approximately 400 basis points higher than the reported 12%.
Q8 What are the key areas management commentary is expected to address?
Management's commentary is expected to focus on 2026 capital spending plans, potential AWS capacity constraints, and the timeline for free-cash-flow recovery. They will also likely discuss the Prime Day timing shift's impact on underlying retail growth.
Q9 What is the primary risk or concern highlighted by the note regarding Amazon's AI investments?
The primary concern is the substantial free-cash-flow outflow associated with AI investment, raising questions about the near-term payoff and how efficiently capital spending will convert into future free cash flow.
Q10 What does the note suggest investors should watch next regarding Amazon and its peers?
Investors should watch Amazon's opening price on Friday versus its after-hours quote, and observe if the pattern of growth being rewarded or punished based on spending continues across other AI-infrastructure names like Alphabet and Microsoft.
