Summary

  • Nutanix reported US$2.548797 billion of ARR at 31 July 2026, up 15.77%. Its definition assumes subscriptions that expire renew on their existing terms and does not incorporate projected cancellation, contraction, expansion or repricing.
  • RPO reached US$3.440411 billion, up 27.77%. Nutanix's latest filed Form 10-Q says this ledger includes deferred revenue and non-cancellable uninvoiced amounts but excludes performance obligations subject to cancellation.
  • The US$891.614 million arithmetic difference is not a demand gap, backlog bridge or revenue forecast. ARR annualises an active subscription base; RPO schedules enforceable contracted revenue not yet recognised.

A renewal can enter the metric before the customer decides

The revealing sentence in Nutanix's annual results is not beside the growth rate. It sits in the definition below the table.

Annual recurring revenue is the sum of annual contract value for subscription contracts in force at the reporting date, assuming any contract that expires is renewed on its existing terms. Nutanix divides a contract's value by its term to obtain annual contract value. Professional services, hardware sales and certain non-portable software and support contracts remain outside the measure.

That construction gives management and investors a consistent view of the active subscription base. It also introduces a hypothetical event. A customer approaching expiry has not yet exercised the next renewal, accepted the same price or retained the same scope. ARR holds those variables still.

The latest filed Form 10-Q makes the boundary unusually explicit. Nutanix does not adjust ARR for known or projected future events—cancellation, expansion, contraction or price changes—that could stop a subscription renewing on its current terms. The company also warns that ARR is not annualised GAAP revenue, not a forecast and not a standardised measure that can safely be compared with an issuer using the same three letters.

At 31 July, ARR was US$2.548797 billion, against US$2.201672 billion one year earlier. The increase was US$347.125 million, or 15.77%. That is strong evidence that Nutanix enlarged the annualised value of subscriptions in force under its stated convention. It is not evidence that every next customer decision has already occurred.

RPO requires a different kind of commitment

Remaining performance obligations approach the future from the other side. The fiscal-2026 results exhibit reports US$3.440411 billion of RPO at July, up US$747.850 million or 27.77% from a year earlier.

The maturity schedule assigns US$1.686685 billion to the current portion, US$1.293675 billion to months 13 through 36 and US$460.051 million thereafter. Approximately 49.03% therefore sits inside the next twelve months, 37.60% in the following two years and 13.37% later.

The table supplies timing, but the 10-Q supplies admission. Nutanix says many contracted but uninvoiced performance obligations carry cancellation terms. RPO includes deferred revenue and non-cancellable amounts that will be invoiced and recognised later. It excludes obligations subject to cancellation.

This is not management being pessimistic in one table and optimistic in another. The measures answer different questions. ARR asks what the active subscription base looks like when annualised under a renewal convention. RPO asks how much contracted revenue remains to be recognised after the accounting boundary tests enforceability. A renewal assumption can support the first measure while a customer cancellation right keeps a different uninvoiced obligation outside the second.

Nutanix does not publish a contract-by-contract map joining those states. It would therefore be wrong to claim that one named customer is counted in ARR and excluded from RPO, or to estimate the amount kept outside RPO. The asymmetry is disclosed at the rule level, not the cohort level.

The subtraction produces a number and no explanation

US$3.440411 billion minus US$2.548797 billion equals US$891.614 million. The calculation is exact. Its commercial interpretation is not.

ARR is an annualised rate built from subscription contracts in effect. A five-year contract is converted into annual contract value. RPO is a stock of transaction price that remains unrecognised and can span the current year, months 13–36 and later periods. It includes deferred revenue and eligible uninvoiced obligations. The populations, units and time structures are different before cancellation language is even considered.

Calling the difference “backlog not in ARR” would ignore the annualisation. Calling it “renewals not in RPO” would invent a bridge. Calling faster RPO growth proof of better retention would confuse enforceable future revenue with a period-end renewal assumption. Calling ARR a revenue forecast would contradict Nutanix's own warning.

The two growth rates can still be read together, cautiously. ARR expanding 15.77% says the annualised subscription base grew. RPO expanding 27.77% says the stock of included contracted revenue awaiting recognition grew faster. The pair supports greater recurring scale and greater contract visibility. It does not reveal how much of either movement came from new customers, expansion, price, term length, early renewals, billing timing or changes in cancellation rights.

The fiscal-year boundary still awaits one filing

There is a final evidence seam. The July results exhibit publishes the year-end RPO table but does not repeat the paragraph about cancellable obligations. That language comes from the April-quarter Form 10-Q, the latest filed policy explanation. The 26 August Form 8-K incorporates the results exhibit, but the fiscal-2026 Form 10-K had not yet appeared in the SEC submissions ledger when this analysis was prepared.

The disciplined reading is therefore conditional: apply the latest filed RPO perimeter while waiting for the 10-K to confirm the year-end language, refinements and risks. Do not silently promote an April footnote into a quotation from a document that has not been filed.
