AMZN: FY25 Deep Dive

FY25 is the year AWS capex caught up with AWS revenue. Capex $131.8B up 59%, FCF compressed from $38B to $11B, and the AWS margin gave back 160bp to 35.4%.

Key Takeaways

Amazon closed fiscal 2025 (calendar year ended December 31, 2025) at $716.9 billion of revenue, up 12% year-over-year. The headline growth story is AWS (+20% to $128.7B) and Advertising (+22% to $68.6B), which together contributed roughly 80% of the dollar-of-operating-income increment. The harder fact to digest is capex — gross property-and-equipment spending stepped up 59% to $131.8 billion, nearly all AWS-directed, and free cash flow compressed from $38.2 billion to $11.2 billion in a single year. AWS operating margin gave back 160 basis points to 35.4% as the capex step-up began flowing through depreciation. Amazon executed zero buybacks for a third consecutive year; the $6.1 billion remaining authorization has sat unused since 2023. Sell-side coverage is 27 analysts with 25 Buy ratings, median price target $290.26, range $175 to $325.

Main business structure

Three reporting segments plus an "Other" line (primarily advertising revenue from Amazon Ads that doesn't roll into a product segment):

Revenue disaggregated by product / service line tells a different story about where growth is coming from:

Advertising is now the fastest-growing line in the company — larger than subscription services and growing at nearly double the rate of online stores. Physical retail (Whole Foods, Fresh, Amazon Go) is the slowest-growing piece and structurally small.

Geographic mix. Roughly 70% US (by customer geography inside North America), 22-23% International, ~8% AWS (which is reported separately from the retail geographic split). AWS revenue is a mix of US and international customers but the 10-K does not disclose the split.

Customer concentration. No single customer accounts for 10% of revenue — the retail base is fragmented across hundreds of millions of consumers, AWS has tens of thousands of enterprise customers with no single one large enough to warrant disclosure.

Scale anchors. Prime members >200M globally. Fulfillment network spans >175 fulfillment centers in North America plus an equally dense international network. AWS runs 34 geographic regions with 108 availability zones as of year-end. Amazon Ads has >1M active advertisers. These are the nouns behind the $131.8B capex line.

Key core metrics (4-year trend)

1. AWS revenue and operating margin

AWS margin expanded 10pp between FY23 and FY24 as server useful lives were extended in accounting estimates; FY25 gave back 160bp as the new capex cycle's depreciation began flowing through. Absolute OI still grew $5.8B YoY — the margin give-back is a pricing question for the Street more than an earnings question.

2. North America segment margin (retail profitability)

Four-year linear improvement from loss-making to 6.9% — better than consensus assumed at FY22 trough, but the rate of improvement is decelerating (180bp → 220bp → 50bp) and 6.9% is likely near the structural ceiling for retail-heavy mix.

3. Capex and FCF

The FY25 FCF compression ($27B YoY decline on +$23.6B OCF growth) is the cleanest single print of what an AI infrastructure cycle costs. Capex intensity: 10% of revenue FY22 (pandemic tail), 8% FY23, 13% FY24, 18.4% FY25. Street models diverge materially on whether FY26 capex stays at or above this level.

4. Capital return (non-return)

Zero capital returned to shareholders for three consecutive years. $6.1 billion remains under the existing repurchase authorization. No dividend. The implicit message is that every dollar of free cash flow is redirected into AWS capex plus balance sheet cash — the cash and marketable securities balance grew from $101.2B (FY24 end) to $123.0B (FY25 end), more than offsetting the $13B long-term debt increase.

Market evaluation

Sell-side coverage (as of late April 2026). 27 analysts cover the stock.

Price targets. Median $290.26, range $175 (low) to $325 (high: Keybanc and BMO Capital).

Recent analyst activity (Feb 23 through April 24, 2026). Zero rating changes in the 60-day window — all 19 covered actions were maintains or reiterates. Largest PT raises: Keybanc ($285 → $325, +$40), BofA ($275 → $298, +$23), Citi ($265 → $285, +$20), JP Morgan ($265 → $280, +$15). No notable PT reductions in the window. The Hold camp (2 analysts, including Rosenblatt in some periods) cites the capex-to-FCF compression as the reason to wait for AWS margin stabilization before re-rating.

Buy-side positioning. Amazon is a consensus large-cap holding with no notable crowded-long or short signals. Short interest remains below 1% of float. Relative to GOOGL / META, AMZN has less single-factor dispersion across sell-side — analysts are largely aligned on the story.

FY25 corporate structure: capex step-up and zero-buyback continuation

Two intertwined structural features dominate FY25. First, the capex step-up ($83B → $132B, a single-year incremental of $49B) reshaped the cash-flow statement in a way that will persist — the FY25 capex base sets the depreciation line for FY26-FY28 regardless of FY26 capex decisions. This is why the AWS margin give-back (37% → 35.4%) matters more than the dollar amount — it is the front edge of a multi-year depreciation wave now locked in. Second, the buyback suspension is now entering its fourth year. The $6.1B unused authorization and $123B of cash and marketable securities mean the company has the capacity to return capital but has chosen not to — management's explicit framing on recent earnings calls has been that AI infrastructure is a better use of capital than buying back shares at current valuations. Whether the Street takes management's framing at face value, or starts to pressure for a capital-return resumption if the AWS margin stabilizes in FY26-FY27, is the single most consequential model-level debate in AMZN coverage.
