Amazon (AMZN) Q3 2025 earnings review
AWS Reaccelerates to 20% Growth, Validating Massive AI Investment Strategy
Amazon delivered strong Q3 results, headlined by a significant reacceleration in its key growth engine, AWS, which grew 20% YoY to a $132 billion annualized run rate. This performance validates the company's aggressive AI investment strategy, which is also visibly pressuring cash flow. Total revenue grew a stable 12% ex-FX to $180.2B. Reported Operating Income was flat YoY at $17.4B, but this was masked by $4.3B in one-time charges; adjusted OI would have been a strong $21.7B. While Net Income was boosted by a $9.5B gain on the Anthropic investment, Trailing-Twelve-Month Free Cash Flow collapsed by 69% YoY to $14.8B, a direct result of a massive ramp in AI-related capital expenditures. Solid Q4 guidance suggests continued stable growth, reinforcing the narrative that Amazon is successfully monetizing its heavy investments in AI capacity.
🐂 Bull Case
The acceleration to 20.2% growth, the fastest in 11 quarters, proves that AWS is capturing a significant share of the AI workload boom and that core cloud migration is resuming. CEO commentary about being supply-constrained suggests growth could be even higher.
The advertising business continues its powerful run, growing 22% YoY (ex-FX). At a nearly $71 billion annualized run rate, it provides a high-margin pillar of support for the company's overall profitability and investment capacity.
🐻 Bear Case
The AI investment cycle is immense. The company guided to ~$125B in CapEx for FY25 and expects to spend more in FY26. This has caused TTM Free Cash Flow to collapse to $14.8B from $47.7B a year ago, a significant cash drain that needs to generate substantial returns to be justified.
$4.3 billion in one-time legal and severance charges obscured underlying profitability. Reported North America operating income fell 15% YoY, which requires careful adjustment to see the true, more modest progress in retail margins.
⚖️ Verdict: 🟢
Bullish. The reacceleration in AWS is the most important data point, confirming the AI thesis is translating into revenue. While the CapEx spend and resulting FCF compression are substantial, they are a direct and necessary investment into a generational opportunity where Amazon is demonstrating clear product-market fit. The strength in advertising provides a stable, high-margin foundation. The investment risk is real, but the current demand signals strongly support the strategy.
Key Themes
AWS Growth Engine Reignites, Fueled by AI Demand
AWS revenue growth accelerated to 20.2% YoY, its highest rate in nearly three years. Management attributes this to strong demand across both core services and new AI workloads. The AI business is seeing significant momentum; custom Trainium2 chips are now a multi-billion dollar business that grew 150% quarter-over-quarter. CEO Andy Jassy noted that AWS is currently supply-constrained, with demand for AI capacity exceeding supply, indicating further room for growth as more data centers and power come online.
AI Investment Crushes Free Cash Flow
The cost of Amazon's AI ambition is starkly visible in its cash flow. Trailing-twelve-month (TTM) Free Cash Flow fell to $14.8 billion, down 69% from $47.7 billion a year ago. This is a direct consequence of TTM purchases of property and equipment surging 78% YoY to $115.9 billion. With the company guiding to approximately $125 billion in CapEx for the full year 2025 and an increase in 2026, cash flow will remain under significant pressure. This is a deliberate strategic bet, but it represents a massive financial commitment.
Advertising Remains a High-Margin Growth Pillar
Amazon's advertising business continues its impressive performance, with revenue growing 24% YoY (22% ex-FX) to $17.7 billion. This marks the third consecutive quarter of growth acceleration. The company is expanding its reach through its Demand Side Platform (DSP) with new partnerships to sell ad inventory on Netflix, Spotify, and SiriusXM, solidifying advertising as a crucial contributor to overall profitability.
Retail Operational Efficiency Continues
Despite facing one-time charges, the underlying health of the retail business remains strong, driven by sustained efficiency efforts. Management noted they are on track for their 'fastest speeds ever' for Prime delivery in 2025. CFO Brian Olsavsky highlighted a nearly 4-day reduction in U.S. inbound lead times, which improves inventory efficiency and working capital. These gains are critical for profitably serving the growing demand for lower-priced 'Everyday Essentials'.
AWS Growth Capped by Supply Constraints
While the AWS reacceleration is a major positive, CEO Andy Jassy stated that the company is monetizing new capacity as fast as it comes online and that growth is constrained by supply, particularly access to power for data centers. He noted that it will take 'several quarters' to fully resolve these bottlenecks. This implies that while demand is robust, near-term growth is capped by physical infrastructure limitations.
Building the 'Agentic' Future of AI and Commerce
Management detailed its strategy to provide the fundamental building blocks for AI agents. The launch of 'AgentCore' provides infrastructure for developers to build secure, scalable agents, with the SDK already downloaded over 1 million times. Internally, Amazon is developing its own agents like 'Kiro' for coding and 'Rufus' for shopping, which is now used by 250 million customers and is on track to deliver over $10B in incremental sales. This signals a major push to lead the next wave of AI applications.
Other KPIs
Reported operating income for the North America segment was $4.8 billion, a 15% YoY decline. However, this included a $2.5 billion charge for a legal settlement with the FTC. Excluding this, adjusted operating income was $7.3 billion, representing strong 29% YoY growth and a healthy 6.9% margin, demonstrating solid underlying profitability from efficiency gains.
The International segment continues its trend of sustained profitability, posting $1.2 billion in operating income. This follows a $1.3 billion profit in the same quarter last year, solidifying the turnaround from prior losses and showing the segment is a consistent positive contributor to earnings.
Guidance
Stable. The midpoint of the range ($209.5B) implies YoY growth of approximately 11.6%. This is in line with the 12% ex-FX growth reported in Q3, suggesting management expects a continuation of the current solid growth trajectory through the holiday season.
The midpoint of $23.5 billion represents solid 11% growth compared to the $21.2 billion reported in Q4 2024. This signals expectations for continued profitability and operational discipline during the company's busiest quarter.
Management expects full-year cash CapEx to be approximately $125 billion, a significant increase from prior years. More importantly, they stated that this amount is expected to increase again in 2026, signaling a multi-year, intensive investment cycle focused on building out AI capacity.
Key Questions
AWS Capacity and Growth
You mentioned being supply-constrained on AI capacity. Can you quantify the revenue impact this had in Q3 and provide more detail on the timeline and strategy for resolving the 'power' bottleneck to meet demand in 2026?
Path to Free Cash Flow Recovery
With CapEx guided to increase again in 2026, TTM Free Cash Flow has fallen nearly 70% YoY. How should investors think about the trough for FCF, and what are the key milestones or demand signals you need to see before CapEx intensity begins to moderate?
North America Retail Margins
Excluding the one-off charge, North America's operating margin was 6.9%, down sequentially from 7.5% in Q2. Are the major efficiency gains from the network redesign now largely realized, or do you see further drivers for margin expansion in 2026?
Agentic Commerce Monetization
Regarding partnerships with third-party shopping agents, what is the envisioned business model? Will it be a referral fee, an ad-based model, or something else, and how will you ensure a high-quality customer experience when purchases are initiated outside of Amazon's direct control?
