What Does Microsoft Do? The Azure Conversion Model

Microsoft books commercial cloud, spends operating cash to stand up Azure halls, and gets paid as remaining performance obligations convert — demand still exceeds available capacity, so the hall is the stuck step.

It is a hyperscaler in the AI build chain: a large cloud operator whose capital spending pulls chips, packaging, halls, and power. The AI cash, and the stuck step, sit in Azure — converting a commercial remaining-performance-obligation book. For that book, see remaining performance obligation, explained. For the specialist-fleet split, see neocloud vs hyperscaler. For a peer that prints megawatts and utilisation, see What Does Oracle Do?.

What does Microsoft actually do?

Three steps, in order.

1. It books commercial cloud. Microsoft sells a broad stack — Microsoft 365, Copilot, GitHub, Dynamics, and Azure. On 29 July 2026 commercial remaining performance obligation grew 84% to $678bn as at 30 June 2026. That is contracted work not yet recognised as revenue. It is not cash in the bank. Hood said the book, including OpenAI, has a weighted average duration of 2.3 years, that roughly 30% will be recognised in the next twelve months, and that remaining performance obligations still rose 25% excluding OpenAI. All sequential growth came from customers outside frontier model companies. See remaining performance obligation, explained.

2. It energises halls and accelerators. That is the operating job that binds. Nadella said Microsoft added another gigawatt of capacity in the quarter, opened 31 new datacentres (88 in the fiscal year), and remains on track to roughly double overall capacity in two years. Hood was blunt: customer demand continues to exceed available capacity. Extra in-quarter capacity was “quickly monetized.”

3. It converts the book into cloud revenue. Azure and other cloud services grew 43%. Intelligent Cloud revenue was $39.306bn, up 32%. Microsoft Cloud was $59.3bn, up 27%. For the full fiscal year Nadella said Azure surpassed $100bn, up 41%, and Microsoft Cloud surpassed $214bn, up 27%. Hood added that nearly 90% of that full-year cloud print came from customers outside frontier model companies. The AI cash sits in Azure. Office and Copilot still earn; they are not the stuck step on this layer.

How does Microsoft make money?

It gets paid when software, seats, and — this cycle — delivered Azure are recognised as revenue. Three things decide how fast the Azure line can grow:

• Delivery — a booked megawatt earns nothing until the hall is live
• Utilisation of what is live — Hood said efficiency gains across the CPU and GPU fleet were quickly monetized because demand still exceeds supply
• Mix and conversion — remaining performance obligations only become revenue on a clock, and Azure is a larger share of the company than it was a year ago

On 29 July 2026 Microsoft printed $90.007bn of total revenue, up 18%. GAAP operating income was $40.603bn. Unlike CoreWeave, it is still profitable on a GAAP operating basis while it spends to stand up AI halls.

Our arithmetic. Microsoft Cloud was $59.3bn, or 65.9% of the $90.007bn total (59.3 ÷ 90.007). Intelligent Cloud was $39.306bn, or 43.7% of sales (39.306 ÷ 90.007). Operating income of $40.603bn is 45.1% of sales, matching the company’s “operating margins … 45%.” Azure is not disclosed as a quarterly dollar line — only as a growth rate and the full-year “surpassed $100bn” print — so we do not invent one.

Cash tells a second story. Operating cash flow was $55.4bn, up 30%. Capital expenditures were $41bn, of which Hood said roughly two-thirds was short-lived assets, primarily CPUs and GPUs. Cash paid for property, plant and equipment was $35.8bn. Finance leases were $5.6bn, primarily large datacentre sites. Free cash flow was $19.6bn. Our check: 55.4 − 35.8 = 19.6. Capex of $41bn is a wider definition than cash PPE; it includes those finance leases.

Who gets paid: Microsoft, for live Azure and for the software that rides on it. Money sticks at energised capacity. The remaining-performance-obligation print is a claim on future delivery.

Custom silicon is a cost claim. Nadella said Maia 200 delivers 30% better performance per dollar than latest fleet hardware — a company claim, dated to the call.

What limits it?

Delivery first. Power and sites second. Mix third.

1. Demand still exceeds available capacity. Adding a gigawatt did not create spare seats. Hood said demand exceeds supply, that this has been true for a number of quarters, and that you can see it in spot-market pricing for assets. Efficiency gains were monetized in the same quarter because the fleet was short. See speed-to-power and the US market door.

2. Remaining performance obligations are not a shipping schedule. Hood said roughly 30% of the $678bn book, including OpenAI, should be recognised in the next twelve months, up 37% year-over-year, and that the portion beyond twelve months rose 112%. Our arithmetic: 30% of $678bn is about $203bn in the next year (0.30 × 678 = 203.4). The other $475bn sits on a longer clock (678 − 203 = 475). $203bn over four quarters is about $51bn a quarter of commercial conversion — against $59.3bn of Microsoft Cloud this quarter, which already includes seats and software that are not Azure consumption. The $678bn print is not $678bn of FY27 Azure.

3. Sites do not all come online at once. Nadella said the company is on track to roughly double overall capacity in two years. That is a multi-year energise clock, not a quarter. Crusoe’s 28 September 2026 note named a 900 MW Abilene campus for Microsoft — a builder print, not a Microsoft IT-megawatt disclosure. See the Wire. Do not back-solve live gigawatts from that campus.

4. Capex is the cash cost of the same bind. Hood guided calendar-year 2026 capital expenditures to approximately $175bn after a useful-life change that shifts more future datacentre leases from finance to operating leases. The underlying plan was unchanged. Q1 FY27 capex is expected over $50bn. FY27 capex “will grow year-over-year.” The company still expects to remain free-cash-flow positive. Microsoft funds the bind from operating cash. The bind is still physical.

The honest uncertainty is conversion. Sold-out demand can still miss an Azure growth rate if halls slip, and a huge remaining-performance-obligation print can miss this year’s Azure. Those are different clocks. +1 GW does not settle both.

Who else does this?

Roles, not a league table.

What separates them is who can deliver accepted megawatts, who funds the hall, and whether demand still exceeds what is live after the add.

What would change this view?

The read on the model weakens if:

• Azure growth slows while remaining performance obligations keep rising — the conversion gap would widen
• Hood’s “demand exceeds available capacity” language disappears in a dated print, which would mean the fleet is no longer the short clock
• Calendar 2026 capex is cut in a way that is not just the finance-to-operating lease reclass
• A named campus slips in a way that does hit the ~45% Q1 Azure guide
• Hyperscaler peers cut 2027 capex — the demand-dial risk on the explained page
• First Vera Rubin / Helios attach is late because packaging or HBM is short — the stuck step would then sit in semiconductors

It stays intact while demand exceeds live capacity after gigawatt adds, Azure keeps converting into a 40%+ growth line, and capex stays funded from operating cash.

Practical takeaways

• Microsoft’s AI model on this layer is Book → Energise → Convert: commercial remaining performance obligations swell; megawatts have to go live; Azure prints after that
• Q4 FY26 (ended 30 Jun 2026): Azure +43%, Microsoft Cloud $59.3bn, remaining performance obligations $678bn, +1 GW added, demand still exceeds supply
• GAAP operating income $40.6bn (45%) and free cash flow $19.6bn — profitable, spending ahead of conversion
• Capex $41bn versus $55.4bn of operating cash flow; roughly two-thirds is short-lived CPUs and GPUs
• About 30% of the $678bn book is the next-twelve-month envelope (~$203bn)
• The stuck step is capacity delivery, not “did Microsoft book another contract”
• Next hard read: Q1 FY27 results (Azure guided ~45% constant currency; capex over $50bn)

FAQ

What does Microsoft do?
Microsoft sells software, Copilot, and cloud. The scarce job is delivering Azure capacity customers can use, then converting remaining performance obligations into recognised cloud revenue.

What does Microsoft do in simple terms?
It books long commercial cloud contracts, switches on data-centre megawatts, and charges for Azure once the hall is actually running.

Is Microsoft profitable?
Yes, on a reported GAAP operating basis. It posted $40.603bn of operating income on $90.007bn of revenue in the quarter ended 30 June 2026 (29 Jul 2026). Free cash flow was $19.6bn. Capex is large; it has not turned the cash engine negative.

How is Microsoft different from a neocloud?
A neocloud sells AI compute as the business. Microsoft sells a broad cloud and still earns from software and seats; Azure is the line that is growing fastest and the step that is stuck. See neocloud vs hyperscaler and What Does CoreWeave Do?.

What is commercial remaining performance obligation?
$678bn of contracted commercial performance not yet recognised as revenue as at 30 June 2026. Hood said roughly 30% should convert over the next twelve months, and that the book still grew 25% excluding OpenAI. It is a backlog clock, not this quarter’s cash.

Should I buy Microsoft shares?
We do not make buy or sell calls, and nothing here is a recommendation. What we can tell you is what the company does, how it gets paid, and which figures would change the picture. The decision is yours.
