| Quarter | Report Date | EPS Actual | EPS Est | Surprise | Revenue | |---------|-------------|-----------|---------|----------|---------| | Q3 2025 | Oct 31, 2025 | $1.43 | $1.14 | +25.4% | $158.9B | | Q2 2025 | Aug 1, 2025 | $1.26 | $1.03 | +22.3% | $148.0B | | Q1 2025 | Apr 29, 2025 | $0.98 | $0.83 | +18.1% | $143.3B | | Q4 2024 | Feb 6, 2025 | $1.86 | $1.48 | +25.7% | $170.0B |
Why Amazon Beats So Big
1. AWS Margin Expansion
AWS operating margins have expanded faster than analysts modeled:
| Quarter | AWS Revenue | AWS Operating Margin | |---------|-------------|----------------------| | Q3 2025 | $27.5B | 38.1% | | Q2 2025 | $26.3B | 35.5% | | Q1 2025 | $25.0B | 37.6% | | Q4 2024 | $24.2B | 36.9% |
Key Insight: Every 100 basis points of AWS margin improvement adds ~$0.15-0.20 to quarterly EPS.
2. Retail Profitability Transformation
Amazon's e-commerce business went from a breakeven unit to a profit center:
| Segment | Q4 2024 | Q3 2025 | Improvement | |---------|---------|---------|-------------| | North America | 6.1% margin | 7.8% margin | +170 bps | | International | -1.2% margin | 2.1% margin | +330 bps |
Drivers:
- Fulfillment network regionalization
- Delivery route optimization
- Third-party seller mix shift
- Advertising revenue growth
3. Advertising: The Hidden Profit Engine
Amazon's advertising business now generates $50B+ annual revenue at 70%+ margins:
| Quarter | Ad Revenue | YoY Growth | |---------|------------|------------| | Q3 2025 | $14.3B | +22% | | Q2 2025 | $12.8B | +20% | | Q1 2025 | $11.8B | +24% | | Q4 2024 | $14.7B | +27% |
Analysts consistently underestimate the margin contribution from advertising.
4. Conservative Guidance Culture
Amazon CFO Brian Olsavsky provides guidance that:
- Accounts for worst-case scenarios
- Includes large reserves for investments
- Bakes in potential one-time costs
Result: Consistent positive surprises when these reserves aren't needed.
Post-Earnings Stock Performance
| Quarter | EPS Surprise | Next-Day Move | Week Move | |---------|--------------|---------------|-----------| | Q3 2025 | +25.4% | +6.8% | +9.2% | | Q2 2025 | +22.3% | +8.3% | +5.1% | | Q1 2025 | +18.1% | +3.2% | +7.4% | | Q4 2024 | +25.7% | +7.9% | +12.3% |
Average next-day move: +6.6%
Pattern: Larger beats (>22%) tend to drive larger moves, but guidance commentary matters significantly.

Why This Matters for Investors
Amazon's consistent 20%+ beats demonstrate:
- Durable competitive advantages in cloud and e-commerce
- Improving profitability across all segments
- Conservative management that under-promises
- Multiple growth engines that diversify risk
The 100% beat rate with 22.9% average surprise suggests estimates may still be too low for 2026.
