Overview
Amazon is a global e-commerce, logistics, advertising and cloud company. For beginners it's a case study in reinvestment: for many years Amazon reported small profits because it poured cash into building warehouses, software, and AWS, businesses that later produced very large profits.
What the company does
Amazon operates the largest Western e-commerce marketplace, a global logistics network, AWS (cloud computing), advertising, Prime subscriptions, and a growing digital media portfolio.
How it makes money
Online retail (first- and third-party), AWS cloud services, advertising on its marketplace, Prime subscriptions, and logistics services sold to merchants.
Moat / competitive advantage
Logistics scale, Prime ecosystem lock-in, marketplace network effects, and AWS's leadership in cloud infrastructure.
Business model breakdown
- •Online stores: first-party retail where Amazon owns the inventory.
- •Third-party services: marketplace fees, fulfillment (FBA) and ads paid by sellers.
- •AWS: cloud infrastructure used by startups, enterprises, and governments.
- •Subscriptions: Prime, which bundles shipping, video, music, and more.
- •Advertising: sponsored placements on Amazon's marketplace.
Key financial concepts to understand
- Segment profitability
- AWS and advertising contribute most of Amazon's operating profit even though retail dominates revenue.
- Capex intensity
- Building warehouses and data centers takes large upfront cash, which reduces free cash flow in heavy investment years.
- Operating leverage
- As fixed logistics and cloud investments mature, incremental revenue tends to convert into proportionally more profit.
Bull case
- •AWS remains a structural growth engine
- •Advertising is a high-margin newer segment
- •Logistics moat keeps deepening
Bear case
- •Retail margins remain thin
- •Heavy capex weighs on free cash flow
- •Antitrust action could restructure the marketplace
Main risks
- •Regulatory scrutiny on marketplace practices
- •Margin pressure from logistics investment
- •Cloud competition from Azure and Google Cloud
- •Cyclical exposure in retail
Valuation questions to ask
- •How much of the value sits in AWS vs retail?
- •What free cash flow profile is realistic after capex?
- •How durable are advertising margins?
What could break the thesis
- •AWS growth durably falling behind cloud peers.
- •Regulation that forces a structural separation of retail and marketplace.
- •Persistent inability to convert revenue into free cash flow after capex.
What beginners should learn
How a company that reinvests almost all profits for many years can build multiple businesses inside one stock, and why that makes valuation harder.
Key terms beginners should know
- Third-party seller
- A merchant selling on Amazon's marketplace, with Amazon taking a fee.
- AWS
- Amazon Web Services. The cloud computing arm.
- Capex
- Long-lived investment in things like warehouses, data centers, and delivery networks.
Questions to research next
- •How is AWS growing relative to Azure and Google Cloud?
- •How large is the advertising segment becoming as a share of profit?
- •How is free cash flow trending as logistics capex normalizes?
