Operating margins have expanded from 2.4% to 11.2% in three years. The multiple has not caught up.
A 29x trailing PE on a $2.25 trillion company sounds like a full valuation. It is, unless you look at what happened to the earnings over the past three years.
Amazon's operating margin in 2022 was 2.4%. By 2025 it had reached 11.2%. Operating income grew from $12.2 billion to $80 billion in that span. Net income went from negative $2.7 billion to $77.7 billion. That is not incremental improvement. That is a business repricing itself.
The market has repriced the stock upward, but the multiple expansion has lagged the earnings trajectory. Forward EPS estimates of $7.77 for 2026 and $9.47 for 2027 put the stock at 27x and 22x forward earnings respectively. An EV/EBITDA of 13.8x sits well below the long-run average for high-quality tech. The margin story is not done, and the valuation does not fully reflect that.
Amazon is three businesses operating under one ticker. Retail is the largest by revenue and the lowest-margin, generating scale and logistics infrastructure that underpins everything else. AWS is the most profitable by absolute dollars, a cloud platform that has compounded at high rates for over a decade and now anchors the AI infrastructure buildout. Advertising is the fastest-growing segment by margin dollar contribution, a business that barely existed a decade ago and now generates revenue in the tens of billions at margins that rival Meta's.
The confusion about Amazon's valuation stems from treating these three businesses as one. A retail company trading at 29x earnings would be expensive. A cloud and advertising platform trading at 29x earnings with 13-14% revenue growth and expanding margins would be a different conversation entirely.
Revenue reached $716.9 billion in 2025, up from $469.8 billion in 2021. That 53% four-year growth on a business of this scale is unusual. What is more unusual is that margins expanded while the revenue base grew. Most companies at this size face the opposite dynamic.

2022 was the low point. Operating income collapsed to $12.2 billion on $514 billion in revenue, a 2.4% operating margin. Amazon had overbuilt its fulfillment network during the pandemic and was absorbing the consequences: excess capacity, elevated labour costs, and a consumer spending slowdown that arrived precisely when the network was at peak cost. The company also absorbed a $12.7 billion write-down on its Rivian investment in that year's net income.
The recovery was faster than most expected. By 2023, operating income had tripled to $36.9 billion, margin reached 6.4%. The fulfillment network had been rightsized. Layoffs in corporate and technology functions reduced the operating cost structure. AWS reaccelerated as enterprise cloud optimization cycles ended.
2024 and 2025 brought the next leg. Operating income reached $68.6 billion in 2024 and $80 billion in 2025. Gross margins expanded every year: 42% in 2021, 43.8% in 2022, 47% in 2023, 48.9% in 2024, and 50.3% in 2025. A gross margin above 50% on a business this size signals the mix shift toward high-margin segments is now structurally embedded, not cyclical.
This kind of margin expansion, sustained across multiple years, is characteristic of a business hitting operating leverage for the first time at scale. Fixed cost bases built during the heavy investment period get absorbed by incremental revenue that flows through at much higher margins. The fulfillment infrastructure that was a burden in 2022 is now largely depreciated and generating returns.
Revenue grew from $514 billion in 2022 to $638 billion in 2024 to $716.9 billion in 2025. That 13.6% year-over-year growth rate is notable for a business that crossed $700 billion in annual sales. Most companies at this scale grow at mid-single digits. The combination of retail, cloud, and advertising growth engines is keeping the compounding rate elevated.
EPS tells the clearest story of the earnings transformation. The trailing twelve months show $7.17 per diluted share. A year prior, after the Rivian write-down and fulfillment cycle, the EPS picture was far murkier. The consensus estimate for 2026 sits at $7.77, rising to $9.47 in 2027. That is a 32% earnings growth path over two years on top of the base that already reflects the margin recovery.
Return on equity reached 22.3% in 2025. That is the number that matters for assessing whether the business has durable earnings power or whether the margin expansion was a one-time event. An ROE of 22% on a business of this size, with a clean balance sheet (net cash positive after netting $86.8 billion cash against $65.6 billion total debt), is the hallmark of a compounding machine.
Earnings beats have been consistent and large. Over the past six reported quarters, Amazon beat consensus EPS estimates by 16.9% to 26.6% in five of them. The one that matched was Q4 2025 at exactly $1.95. The pattern of sustained estimate beats at this scale typically indicates that sell-side models are structurally underestimating the earning power of the underlying business.
AWS is the engine most investors understand. It is the largest cloud platform by market share, a business that compounds at high rates with predictable renewal economics and expanding margins as AI workloads increase utilization. AWS revenue is reported within Amazon's financial statements and carries margins far above the company average. The AI infrastructure buildout is a direct tailwind: every enterprise migrating AI workloads to cloud is a net revenue event for AWS, and the April 2026 reports of Amazon advancing AI and satellite expansion plans suggest the investment cycle continues to attract customer commitments.
Advertising is the engine most investors undervalue. Amazon's advertising segment generates revenue from sponsored product placements, display advertising, and video advertising through Prime Video. The structural advantage is unusual: Amazon sits at the point of purchase intent. When someone searches for running shoes on Amazon and sees a sponsored result, the advertiser is reaching a buyer, not a browser. That conversion advantage commands premium pricing that Facebook and Google cannot fully replicate.
Advertising revenue is not broken out separately in the financial statements used here, but gross margin expansion from 42% in 2021 to 50.3% in 2025 tracks directly with advertising's growing revenue contribution. High-margin advertising dollars flowing into a cost structure sized for lower-margin retail creates automatic operating leverage. The mix shift does the work.
The combination of AWS and advertising now gives Amazon a profit engine that is largely decoupled from retail economics. Retail still drives traffic and data. The margins come from elsewhere. That structural change is what the trailing PE ratio does not fully capture.
Capital expenditure reached $131.8 billion in 2025, up from $83 billion in 2024 and $52.7 billion in 2023. Operating cash flow grew to $139.5 billion, leaving free cash flow of just $7.7 billion. That is a sharp compression from the $32-33 billion FCF generated in 2023 and 2024.
The capex is predominantly AI infrastructure: data centers, custom chips (Trainium and Inferentia), network expansion, and satellite broadband through Project Kuiper. This is not maintenance spending. It is investment in the next generation of AWS capacity at a moment when AI compute demand is growing faster than supply.
The relevant question is not whether capex is high. It clearly is. The relevant question is whether the incremental return on that capital will exceed the cost of deploying it. The history of Amazon's capex cycles suggests the answer is yes, but the gap between operating cash flow and free cash flow is wide enough to give investors pause. Paying 29x trailing PE while FCF is effectively zero requires confidence in the forward earnings trajectory that not every investor will have.
Operating cash flow of $139.5 billion is the number that matters for understanding the underlying cash generation of the business before growth investment. That figure grew from $84.9 billion in 2023 to $115.9 billion in 2024 to $139.5 billion in 2025 — a 64% increase in two years. The business generates cash at scale. The question is how long the capex absorption phase lasts.
At $210 per share, Amazon trades at 29.3x trailing earnings and 25.8x forward earnings. EV/EBITDA sits at 13.8x, which is low for a business with this margin profile and growth rate. The PEG ratio of 1.6x is consistent with fair-to-moderate value on a growth-adjusted basis.
Wall Street's consensus target of $281 implies roughly 34% upside from current levels. The analyst distribution is skewed sharply bullish: 47 strong buy, 19 buy, 4 hold, zero sell or strong sell. Consensus is rarely right on magnitude, but the direction of the analyst community reflects a view that the forward earnings trajectory justifies a higher multiple than the current one.
The most interesting valuation data point is EV/EBITDA of 13.8x. EBITDA was $165.3 billion in 2025, up from $123.8 billion in 2024 and $85.5 billion in 2023. An enterprise value of approximately $2.28 trillion applied to a $165 billion EBITDA base that has grown 93% in two years is an unusual setup. By this measure, the stock is not expensive relative to earnings quality and trajectory.
Forward EPS of $9.47 in 2027 would put the stock at 22x two-year-forward earnings at today's price. If the margin expansion thesis holds, which the gross margin trajectory supports, that multiple could look conservative in retrospect.
Revenue at $716.9 billion growing at 13.6% year-over-year requires substantial engines. Three are doing the work. AWS is accelerating as AI compute demand fills newly built data center capacity. Advertising is growing faster than the overall business as the customer base scales and Prime Video advertising becomes more material. International retail is still in earlier profitability stages than North America, providing a runway for margin expansion as those markets mature.
The AI investment cycle is both a capex burden and a growth catalyst. Amazon's custom silicon efforts, Trainium for training and Inferentia for inference, are designed to reduce the unit economics of AI compute for AWS customers while protecting Amazon from margin compression as competition intensifies. If the chip strategy succeeds, AWS maintains pricing power even as the market grows.
Geographic expansion remains underappreciated. Amazon's international segment has moved from losses to profitability over the past two years, and the margin improvement path for international retail mirrors what North American retail experienced three to four years earlier. That structural lag creates a predictable source of margin expansion independent of AWS and advertising performance.
The dominant theme in current market coverage of Amazon is AI, reflecting the investment cycle and the broader positioning of AWS in the enterprise AI buildout. That theme is real, but the advertising maturation story is equally important to the margin trajectory and receives less attention.
The FCF compression is the most immediate risk. At $7.7 billion in free cash flow against a $2.25 trillion market cap, the FCF yield is negligible. Investors relying on FCF valuation models are looking at a business that currently returns almost nothing in cash relative to its price. If the capex cycle extends further, or if AWS growth disappoints, the argument for current multiples becomes harder to sustain.
Antitrust exposure is real and has been accelerating. The FTC's ongoing scrutiny of Amazon's marketplace practices and Prime bundling raises the possibility of structural remedies that could constrain the advertising revenue model or third-party seller economics. These proceedings move slowly, but the direction of regulatory risk is not favorable.
Tariff-related disruption to the third-party seller ecosystem represents a more immediate pressure. Amazon's marketplace is heavily populated by Chinese merchants and brands. Escalating trade restrictions could disrupt that supply chain, reduce selection, and put pressure on the fee revenue Amazon earns from those sellers. This is a 2026 risk that the word weights data suggests is already featuring prominently in market coverage.
AWS competition from Microsoft Azure and Google Cloud is intensifying. Both competitors are investing aggressively in AI infrastructure and have deep enterprise relationships that Amazon does not always have. The AI workload share of new cloud contracts is a battleground where the outcome is not predetermined.
Amazon's trailing PE of 29x is the wrong number to anchor on. The business that generated those trailing earnings is structurally different from the business that existed three years ago, and the forward earnings trajectory suggests the transformation continues.
Operating margins went from 2.4% in 2022 to 11.2% in 2025. Gross margins crossed 50%. Net income reached $77.7 billion. Operating cash flow hit $139.5 billion. EV/EBITDA sits at 13.8x on an EBITDA base that grew 93% in two years. These are not the characteristics of a business that is expensive on forward fundamentals.
The risks are real. FCF is compressed by a $131.8 billion capex commitment. Antitrust and tariff exposure add uncertainty. The capex cycle duration is unknown. But investors who dismiss the stock at 29x trailing PE without examining the earnings trajectory are applying a static lens to a dynamic business. At 22x two-year-forward earnings with this margin profile and growth rate, the risk-adjusted case is more compelling than the headline multiple suggests.

From 5.3% to 11.2% operating margin in four years. Now the company is spending $131.8 billion in a single year. This is either the best capital allocation decision in tech history or a very expensive bet on demand that may not materialise.
Operating income has grown sixfold since 2022. The market still thinks it is buying a retailer.
The market still prices Amazon as a retailer. The financials say otherwise.
