Amazon Q3 Earnings Miss: AWS Shines, But Capex Concerns Loom

Amazon.com (AMZN) reported third-quarter earnings after the close on Thursday, and the market's reaction was swift and negative. The stock closed down 4.25% at $243.79 ahead of the report, and fell further in after-hours trading as investors digested the results. Trading volume was unusually high at 70.8 million shares, about 81% above the three-month average, indicating strong investor interest and concern.

The headline numbers missed Wall Street expectations. Amazon reported revenue of $201.9 billion, up 12% year over year, but below the consensus estimate of $202.2 billion. Earnings per share came in at $1.89, missing the expected $1.97. The company also provided fourth-quarter revenue guidance of $240 billion to $247 billion, with the midpoint slightly below analysts' average estimate of $244.51 billion.

The miss was not due to weakness in Amazon's cloud business. AWS, the company's cloud computing division, delivered impressive growth. Sales accelerated to 39% year over year to $46 billion, up from 37% growth in the previous quarter. The AI boom is driving demand, and Amazon announced new agreements with Meta and Salesforce. Management even projected that AWS revenue growth will exceed 40% in both 2027 and 2028.

However, investors focused on the company's massive capital expenditure plans. Amazon is set to spend $220 billion in 2026, a staggering sum that raises questions about return on investment and near-term profitability. The capex is aimed at expanding AWS infrastructure to meet AI demand, but the market is clearly nervous about the pace of spending.

The broader market also had a negative tone. The S&P 500 fell 0.31% to 7,720, while the Nasdaq Composite dropped 1.38% to 26,185. Interestingly, traditional retail peers like Walmart and eBay gained ground, suggesting a rotation away from Amazon following its earnings disappointment.

Amazon is a bellwether for both e-commerce and cloud computing, so its earnings have wide-ranging implications. The miss on revenue and EPS, combined with cautious guidance, signals that consumer spending might be softening and that the company is willing to sacrifice short-term profitability for long-term growth. This is a classic Amazon playbook, but in a high-interest-rate environment, investors are less patient with heavy spending.

The $220 billion capex plan is a double-edged sword. On one hand, it demonstrates Amazon's commitment to maintaining its lead in cloud computing and AI infrastructure. AWS is the profit engine of the company, and its accelerated growth to 39% is a testament to the AI boom. On the other hand, such massive spending could pressure free cash flow and earnings in the near term, especially if the economy slows.

Competitively, Amazon's strong AWS growth puts pressure on rivals like Microsoft Azure and Google Cloud. The new deals with Meta and Salesforce show that AWS remains a preferred partner for large enterprises. However, the capex concerns could also be a warning sign for the entire tech sector, which has been investing heavily in AI. If Amazon's spending doesn't translate into proportional profit growth, other companies might face similar scrutiny.

The mixed read-through for retail is also notable. Walmart and eBay both gained, suggesting that investors might be rotating into more traditional retail names that are less exposed to the high-stakes AI capex race. This could indicate a broader shift in market sentiment, where profitability and cash flow are favored over growth-at-all-costs.

For long-term investors, the key question is whether Amazon's capex will generate sufficient returns. Management's projection of AWS growth exceeding 40% in 2027 and 2028 is ambitious, but if achieved, it would justify the spending. The market's negative reaction reflects short-term disappointment, but the long-term story remains intact.
