Amazon (AMZN) Q4 2025 earnings review
AWS Reaccelerates to 24%, But Massive CapEx Crushes Free Cash Flow
Amazon delivered a strong Q4 with revenue of $213.4B (+12% ex-FX) and operating income of $25.0B (+18% YoY), though $2.4B in special charges masked even stronger underlying performance. AWS was the headline: 24% growth—its fastest in 13 quarters—on a $142B run rate. Advertising grew 22% to $21.3B. EPS of $1.95 beat the year-ago $1.86 by 5%. But the elephant in the room is capital spending: $128.3B in trailing PP&E purchases drove free cash flow down 71% to $11.2B. Management guided $200B in 2026 CapEx, betting aggressively on AI infrastructure. Q1 2026 guidance of $173.5-178.5B in revenue (+11-15%) looks solid, but operating income of $16.5-21.5B signals margin pressure from Leo satellite launches and international investments.
🐂 Bull Case
AWS grew 24% on a $142B base—its fastest rate since Q3 2022. Backlog surged 40% YoY to $244B. Custom silicon (Trainium + Graviton) crossed $10B in annual run rate with triple-digit growth. Every dollar of AI capacity is being monetized immediately upon installation.
Cost-to-serve declined for the third straight year while delivery speeds hit new records. Same-day deliveries up 70% YoY in the U.S. Paid units grew 12%, the highest quarterly rate in 2025. Everyday essentials now represent 1 in 3 units sold, and grocery gross sales exceeded $150B.
Ads generated $21.3B (+22% YoY), adding $12B+ in incremental revenue for the full year. Prime Video's ad-supported audience grew from 200M in early 2024 to 315M globally. Full-funnel approach and AI-powered creative tools are expanding the addressable market.
🐻 Bear Case
FCF collapsed 71% to $11.2B on a trailing basis as PP&E purchases surged 65% to $128.3B. Management just guided $200B in 2026 CapEx. Even with $139.5B in operating cash flow, free cash flow will remain under severe pressure for years—and the return timeline is uncertain.
International operating margin dropped from 3.0% to 2.1% YoY, with operating income falling 21% to $1.0B despite 17% revenue growth. Management is deliberately investing in sharper pricing and quick commerce. Guidance signals continued margin pressure.
⚖️ Verdict: 🟢
Bullish. AWS's 24% reacceleration on a $142B base, combined with $244B in backlog and the retail flywheel hitting new highs, outweigh the FCF concerns. The CapEx cycle is heavy, but Amazon is monetizing capacity immediately and has a track record of turning large investments into durable returns. International margin compression is the key risk to monitor.
Key Themes
AWS Reacceleration: 24% Growth, Fastest in 13 Quarters
AWS growth accelerated from 17% in Q1 to 24% in Q4 on a $142B annualized run rate—adding $6.8B in YoY revenue in the quarter alone. The acceleration is driven by both AI services and a resurgence in core cloud migrations. Bedrock (managed inference) is a multi-billion-dollar run rate business with customer spend up 60% quarter-over-quarter. The company added 1.2 GW of power in Q4 alone (3.99 GW in the past 12 months—double 2022 capacity) and plans to double again by end of 2027. AWS operating margin held at 35.0%, up 40 bps YoY despite heavy depreciation from the investment cycle.
Custom Silicon Crosses $10B Run Rate
Trainium + Graviton combined now exceed $10B in annual revenue run rate with triple-digit YoY growth. Trainium2 has 1.4M+ chips landed (fastest ramp ever), powering the majority of Bedrock inference and used by 100,000+ companies. Trainium3, offering 40% better price-performance than Trainium2, just started shipping with nearly all supply expected committed by mid-2026. Trainium4 (2027) and Trainium5 are already generating significant customer interest. Graviton, the custom CPU, is used by 90% of the top 1,000 AWS customers. This is a structural margin advantage: custom silicon gives Amazon both better customer pricing and better unit economics.
Free Cash Flow Collapse: $11.2B vs $38.2B a Year Ago
Trailing twelve-month free cash flow fell 71% to $11.2B as PP&E purchases surged to $128.3B (up $50.7B YoY). This marks the fifth consecutive quarter of FCF decline. Management guided approximately $200B in 2026 CapEx across Amazon (predominantly AWS). While operating cash flow grew 20% to $139.5B, the capital intensity has fundamentally changed the cash generation profile. No buyback program was discussed. Cash and equivalents rose to $86.8B (partially from $15.7B in new long-term debt issuance), providing a buffer.
International Segment Margin Deterioration
International operating margin declined from 3.0% in Q4 2024 to 2.1% in Q4 2025, with operating income falling 21% to $1.0B despite 17% revenue growth (11% ex-FX). This reverses a multi-quarter improvement trend (margin peaked at 4.1% in Q2 2025). Management attributed this to deliberate investment: quick commerce expansion (Amazon Now in India, Mexico, UAE), aggressive pricing to match or beat competitors, and the $1.1B Italy tax/lawsuit settlement charge. The TTM international margin also contracted from 2.7% to 2.9% but was impacted by special charges. Management frames this as growth investment but margin visibility is poor.
Advertising: $21.3B Quarter, 22% Growth, Full-Funnel Expansion
Advertising revenue grew 22% YoY to $21.3B, adding $12B+ in incremental revenue for the full year. Growth was consistent: 19% in Q1, 22% in Q2, 22% in Q3, 22% in Q4 (all ex-FX). Prime Video's ad-supported audience reached 315M global viewers, up from 200M in early 2024. New AI-powered tools—an ads agent for campaign optimization and a creative agent for full-funnel ad creation—are reducing advertiser friction. The DSP expanded inventory partnerships with Roku, Netflix, Spotify, and Disney. Ads are Amazon's highest-margin revenue stream and now run at an $85B+ annual rate.
Delivery Speed Flywheel: Cost-to-Serve Down, Speed Up, Volume Up
For the third straight year, Amazon achieved both fastest-ever delivery speeds and lower cost-to-serve. U.S. Prime members received 8B+ items same/next day (+30% YoY), with groceries and essentials making up half. Same-day deliveries up 70% YoY, used by nearly 100M customers. The regionalized network expanded from 8 to 10 regions, inbound logistics were redesigned, and units per box improved. Add to Delivery, launched six months ago, already accounts for ~10% of weekly Prime volume. Quick commerce (Amazon Now—30-minute delivery) launched in India, Mexico, and UAE, with Indian customers tripling their shopping frequency.
Agentic AI: The Next Platform Shift for AWS and Retail
Management positioned agents as the primary way companies will extract value from AI. AWS launched Bedrock AgentCore (secure deployment), Strands (agent creation), and Frontier Agents (autonomous, long-running). Specialized agents include Kiro (coding, 150%+ QoQ developer growth), Amazon Q (knowledge workers), AWS Transform (migration), Connect ($1B+ run rate, 20M+ daily interactions), and DevOps/Security agents. On the retail side, Rufus served 300M+ customers, drove ~60% higher purchase completion rates, and now shops external stores via Buy for Me. Nova Forge launched to let enterprises build custom AI models with proprietary data baked into pre-training.
$2.4B in Special Charges Obscure Underlying Performance
Q4 operating income of $25.0B included three special charges totaling $2.4B: $1.1B for Italy tax disputes and a lawsuit settlement (International segment), $730M in severance costs (all segments), and $610M in asset impairments on physical stores (North America). Without these, adjusted operating income would have been $27.4B. This follows $4.3B in special charges in Q3 ($2.5B FTC settlement, $1.8B severance). The pattern of recurring 'one-time' charges warrants monitoring.
Amazon Leo Satellite Network Ramping Toward Commercial Launch
Amazon Leo (formerly Kuiper) has 180 satellites launched, with 20+ launches planned in 2026 and 30+ in 2027. Leo Ultra terminal delivers 1 Gbps download / 400 Mbps upload with enterprise-grade encryption connecting directly to AWS. Commercial launch expected in 2026. Signed agreements with AT&T, DIRECTV Latin America, JetBlue, and Australia's National Broadband Network. Leo costs currently expensed as incurred—adding ~$1B YoY to Q1 2026 operating costs—but will shift to capitalization later in 2026 as satellite manufacturing and launch costs qualify.
AWS Margin Compression Risk From CapEx Depreciation
AWS operating margin was 35.0% in Q4, up 40 bps YoY but down from 39.5% in Q1 2025. TTM AWS margin contracted from 37.0% to 35.4%. The depreciation wave from $128B+ in annual PP&E purchases is a structural headwind: depreciation and amortization rose 25% YoY to $65.8B for the full year. Management stated margins will 'fluctuate over time' based on investment levels. Custom silicon and operational efficiencies are offsetting some pressure, but the scale of the investment cycle suggests margins may remain range-bound or decline before improving.
Grocery at $150B+ Gross Sales—A Structural Growth Driver
Amazon is now a $150B+ gross sales grocer serving 150M+ Americans through online delivery and Whole Foods. Same-day perishable delivery expanded to 2,300+ U.S. cities, with perishables being 9 of the top 10 ordered items in those areas. Customers who buy perishables shop twice as frequently. Plans to open 100+ new Whole Foods stores over coming years. Everyday essentials grew nearly 2x faster than other U.S. categories, now 1 in 3 units sold. This high-frequency category increases mindshare and total wallet capture.
Other KPIs
Accelerating. Up from 8.0% in Q4 2024, marking the highest Q4 margin in the segment's history. The improvement came despite $610M in physical store impairments and severance charges. Excluding special items, underlying margin expansion was even stronger. TTM margin reached 6.9%, up from 6.4% a year ago. The fulfillment network's third consecutive year of cost-to-serve improvement, combined with strong advertising revenue contribution, are the primary margin drivers.
Accelerating. Up 20% from $115.9B in FY24, driven by higher operating income ($80.0B vs $68.6B) and improved working capital management. The 20% growth re-accelerated from 15% in the TTM through Q1 2025. However, nearly all of this cash flow—and more—is being reinvested: $131.8B in gross PP&E purchases in FY25, guided to ~$200B in FY26. Long-term debt rose to $65.6B from $52.6B as Amazon took on $15.7B in new debt to fund the investment cycle.
Up 31% from $59.2B ($5.53 EPS) in FY24. However, FY25 included $15.2B in non-operating income (largely from Anthropic investment gains, including $9.5B in Q3 alone). Excluding non-operating items, operating income grew a more modest 17% to $80.0B. The Q4 net income of $21.2B (+6% YoY) was held back by a $4.9B tax provision (vs $2.3B year-ago) and $467M in equity-method losses. Effective tax rate spiked to 18.6% from 10.4% in Q4 2024.
Stable. Up 14% YoY (12% ex-FX), consistent with the 10-12% growth range seen throughout 2024-2025. Prime membership continues to grow, with the value proposition strengthened by faster delivery, expanded grocery, Prime Video sports content (TNF, NBA, NASCAR, UEFA), and the inclusion of Alexa+ for Prime members. This is Amazon's most recurring revenue stream.
Guidance
Stable growth. Midpoint of $176.0B implies 13% YoY growth (vs $155.7B in Q1 2025), consistent with Q4's 14% reported growth rate. Includes ~180 bps favorable FX impact, so ex-FX growth at midpoint is ~11%. This continues the pattern of steady 10-12% ex-FX growth seen throughout 2025.
Potentially decelerating. Midpoint of $19.0B implies 3% growth vs Q1 2025's $18.4B, a sharp slowdown from 18% OI growth in Q4. The wide $5B range reflects uncertainty. Key headwinds: ~$1B YoY increase in Leo satellite costs (currently expensed), continued international pricing and quick commerce investment, and the ongoing depreciation wave from CapEx. Midpoint implies 10.8% operating margin, down from 11.8% in Q1 2025.
Accelerating significantly. Up from $131.8B (gross) in FY25, a 52% increase. The vast majority is for AWS AI infrastructure. Jassy framed this as an 'extraordinarily unusual opportunity' and committed to aggressive investment to maintain leadership. Trainium demand, power capacity expansion (targeting 2x 2025 levels by end of 2027), and core cloud growth all drive the spend. Implied quarterly run rate of ~$50B vs ~$33B average in FY25.
Accelerating. Up 40% YoY and 22% QoQ, a significant acceleration from the 25% YoY growth reported in Q2 2025 ($195B) and 20% in Q1 ($189B). This is forward-looking revenue visibility and represents multi-year commitments. The acceleration in backlog growth alongside the acceleration in recognized revenue is a strong demand signal.
Key Questions
Free Cash Flow Floor
With $200B in planned 2026 CapEx and FCF already down to $11.2B, is there a minimum FCF or maximum leverage threshold management is targeting? At what point does the investment cycle begin generating positive incremental FCF?
International Margin Trajectory
International operating margin declined to 2.1% despite strong revenue growth. How much of this is the Italy charge vs. ongoing investment in quick commerce and pricing? What is the timeline for Amazon Now and sharper pricing to generate positive returns?
AWS Demand vs. Capacity Quantification
You've consistently said demand exceeds supply. Can you quantify the gap—how much faster could AWS grow with unconstrained capacity? And what is the expected cadence of capacity additions through 2026?
Depreciation Impact on 2026 Margins
With gross PP&E jumping from $132B to $200B, what is the expected incremental depreciation expense in FY2026? How much can operational efficiencies and custom silicon realistically offset?
Leo Economic Model
Leo costs are currently expensed but will shift to capitalization later in 2026. What is the expected total Leo investment through commercial launch, and what is the path to breakeven for this business?
