Amazon reports 23% ad revenue growth and 24% AWS growth in Q4, but shares fall 10%+ after hours as the company boosts 2026 capex to $200B amid AI infrastructure expansion.
Amazon's fourth-quarter earnings revealed a company in transition, with strong growth in advertising and cloud services offset by investor concerns about rising infrastructure costs and mixed overall performance.
Advertising and Subscription Services Show Strong Growth
Amazon's advertising business delivered another quarter of robust growth, with revenue up 23% year-over-year to $21.32 billion, slightly above analyst expectations. This marks continued momentum for Amazon's ad platform, which has become a significant profit driver for the company.
The subscription services segment also performed well, growing 14% to $13.12 billion. This includes Prime memberships and other subscription offerings that have become increasingly central to Amazon's business model.
AWS Maintains Strong Momentum
Amazon Web Services, the company's cloud computing division, reported revenue of $35.6 billion, up 24% year-over-year and exceeding the $34.9 billion estimate. Operating income for AWS reached $12.5 billion, up 17% from the previous year.
This performance underscores AWS's continued dominance in the cloud market, even as competitors like Microsoft Azure and Google Cloud Platform invest heavily to close the gap. The 24% growth rate represents acceleration from previous quarters, suggesting AWS is benefiting from the ongoing enterprise shift to cloud computing and increased AI-related workloads.
Mixed Overall Results and Investor Reaction
The company reported total revenue of $213.4 billion, up 14% year-over-year, with net income of $21.19 billion and earnings per share of $1.95, slightly below the $1.97 estimate. Following the earnings release, Amazon shares plunged more than 10% in after-hours trading.
Massive Infrastructure Investment Plans
The most significant revelation from the earnings call was Amazon's plan to boost capital expenditures in 2026 to $200 billion. This represents a substantial increase from previous years and reflects the company's aggressive push into AI infrastructure.
"The company is investing heavily in AI capabilities across its business," Amazon executives noted during the earnings call, though specific AI revenue figures were not broken out separately.
This massive capex increase has raised questions among investors about the return on investment timeline for these AI infrastructure projects. The market's negative reaction suggests concerns that Amazon may be overspending relative to near-term revenue opportunities.
Competitive Landscape and Market Position
Amazon's results come amid a broader tech sector selloff, with software stocks particularly hard hit. The company faces increasing competition across its business segments:
- In cloud computing, Microsoft and Google are investing heavily in AI capabilities to challenge AWS's market leadership
- In e-commerce, Walmart and other retailers continue to invest in their digital platforms
- In digital advertising, Google and Meta remain formidable competitors
Strategic Implications
The earnings highlight Amazon's dual strategy of maintaining its core e-commerce and cloud businesses while investing heavily in next-generation AI infrastructure. This approach carries risks but also positions Amazon to potentially capitalize on the AI revolution.
The strong performance in advertising and AWS suggests these mature businesses can fund the company's ambitious AI investments. However, the market's reaction indicates investors want to see clearer paths to profitability from these massive infrastructure investments.
Looking Ahead
As Amazon navigates this transition, several factors will be critical to watch:
- AI Revenue Attribution: How quickly Amazon can monetize its AI investments across AWS, Alexa, and other services
- Margin Pressure: Whether the massive capex increases will impact overall profitability in the near term
- Competitive Response: How competitors respond to Amazon's infrastructure investments
- Consumer Adoption: The uptake of AI-enhanced features in Amazon's consumer products and services
The company's ability to balance its traditional strengths with aggressive AI investments while maintaining profitability will be crucial for its long-term success in an increasingly competitive tech landscape.
