Key Highlights

● AWS Revenue reached $46.0 billion, ahead of the roughly $45.3 billion expected.

● Earnings of $1.89 a share missed the $1.96 to $1.97 consensus.

● Fourth-quarter sales guidance of $240 billion to $247 billion had a midpoint below consensus.

● Trailing free Cash Flow was negative $42.4 billion against positive $14.8 billion a year earlier.

Amazon (NASDAQ:AMZN)'s cloud division posted its strongest growth in years on Thursday, but a softer holiday forecast and a deep cash outflow sent the shares sliding in extended trading.

A cloud quarter worth celebrating

Amazon Web Services gave investors much of what they had hoped for. The unit's revenue reached $46.0 billion, ahead of the roughly $45.3 billion analysts expected, according to market data. One technology news headline described it as AWS's fastest growth in about five years.

The division also posted a record operating margin, and Amazon said AWS expects growth to speed up further in 2027 and 2028. On the cloud side, at least, the quarter delivered.

So why did the stock fall?

The rest of the report was less inspiring. Total net sales of $201.9 billion were roughly in line with forecasts, but Earnings of $1.89 a share fell short of the $1.96 to $1.97 analysts expected, according to market data and other reports.

The forward view disappointed too. Amazon guided to fourth-quarter sales of $240 billion to $247 billion, with a midpoint below the roughly $244.5 billion consensus. The holiday quarter is the most important stretch of the year for Amazon's retail operation, so a cautious guide carries extra weight.

Then there was the cash. Trailing twelve-month free cash flow came in at negative $42.4 billion, compared with positive $14.8 billion a year earlier. Amazon also reaffirmed its 2026 Capital spending plan of $220 billion.

The after-hours reaction

Amazon's shares had already fallen during the regular session, closing at $243.79 as Alphabet (NASDAQ:GOOGL)'s slump weighed on Big Tech. After the report, they dropped further. One source had the stock near $226.91 in extended trading, while another reported a steeper decline at the worst point before the losses were trimmed. Reports on the size of the drop varied with the time of each snapshot.

The selling spilled into futures. According to market data, Nasdaq-100 futures slid after the bell on the Amazon and Intel (NASDAQ:INTC) declines, while S&P 500 futures also fell and Dow futures edged higher.

The cash-flow lens

Amazon's reaction makes sense in light of Thursday's broader theme. Investors spent the day punishing companies whose AI spending outpaces their cash generation. Alphabet suffered its worst day since its 2004 IPO after reporting negative free cash flow of $9.07 billion, while Microsoft (NASDAQ:MSFT) held up after what one report called "a big cash-flow beat."

One market strategist said that "markets are no longer rewarding companies simply for investing heavily in AI." Amazon's AWS acceleration shows the spending is producing growth, but the cash outflow shows the bill is still large.

CEO Andy Jassy struck an ambitious tone: "There has never been a trillion dollar revenue business, and we may have two of them in the next 5 to 10 years."

The session backdrop

During regular hours, the broader market split in two. The Nasdaq Composite dropped 365.13 points to 26,184.72 and the S&P 500 slipped 23.59 points to 7,720.39. Yet more than 400 S&P 500 members rose, and the Russell 2000 gained 28.71 points to 2,859.22. Consumer discretionary, the sector that includes Amazon, finished lower.

What to watch

Friday's regular session will show where Amazon's shares settle once after-hours Volatility gives way to full trading. Analysts' revisions to price targets and estimates will follow.

Beyond that, the key questions are whether AWS can deliver the faster growth it projected for 2027 and 2028, and when the free cash flow trend turns. With $220 billion in capex reaffirmed, investors will look for evidence that the spending translates into returns. The holiday quarter will also matter: if retail outperforms the cautious guide, sentiment could recover quickly.
