Follow the Money: What Oura’s S-1 Reveals—and Doesn’t Reveal—About Its Membership Business

Oura’s membership economics remain opaque. Its receivables nearly doubled. And before inviting the public to invest, the company spent approximately $1.48 billion buying shares from existing holders.

When I began examining Oura’s S-1, I was looking for the answer to a simple question:

The filing does not provide that answer.

It provides an impressive collection of headline figures: 5.0 million “Paid Members,” $240.5 million in membership revenue for the nine months ended June 30, 2026, 121% year-over-year membership-revenue growth, an 89% membership gross margin, $137.3 million in deferred revenue, and approximately 85% weighted-average 12-month Paid Member retention.

But these numbers describe different things.

A member is not necessarily the person paying. Revenue is not the same as cash collected during the period. Deferred revenue is cash collected before the related service has been delivered. And “Paid Member,” as Oura defines the term, does not necessarily mean a member currently paying Oura.

This article examines the financial question only. The construction of Oura’s 85% retention statistic—including winbacks, grace periods and free concessions—will be examined separately in Part II.

Oura is still primarily a hardware business

For the nine months ended June 30, 2026, Oura reported:

Oura sold approximately 3.1 million rings during those nine months. Dividing $974 million of hardware revenue by 3.1 million rings produces approximately $314 in recognized hardware revenue per ring. That is not necessarily the consumer retail price because it incorporates wholesale pricing, product mix, discounts, returns and other adjustments.

Oura’s U.S. membership costs $5.99 per month or $69.99 per year. The annual membership price is therefore approximately 22% of the average recognized hardware revenue per ring.

The hardware produces the large initial sale. The membership produces recurring, high-margin income that can support a much higher valuation. That is why the membership figures deserve close examination.

Oura reported an 89% membership gross margin. At $240.5 million of membership revenue, this implies approximately $214 million of membership gross profit before operating expenses.

This is an extremely attractive financial engine—if the underlying membership revenue is durable, independently paid and genuinely recurring.

Revenue, billings and cash are three different things

1. Cash collected

This is the money Oura actually receives. If a customer pays $69.99 for an annual membership on January 1, Oura receives the cash immediately.

2. Revenue recognized

Oura has not earned all $69.99 on January 1 because it still owes the customer 12 months of service. It recognizes approximately one-twelfth of the payment as revenue each month.

3. Deferred revenue

The amount collected but not yet earned remains on the balance sheet as deferred revenue. It is a liability because Oura still owes the customer future service.

This is normal subscription accounting. Deferred revenue is not inherently suspicious.

Was it an individual consumer, employer, insurer, health plan, enterprise customer, retail partner, or a partner purchasing memberships in bulk? Oura does not disclose the answer.

The $240.5 million is revenue—not current-period cash collections

Oura disclosed that $78.7 million of revenue recognized during the nine months had already been included in deferred revenue at September 30, 2025.

In plain English, Oura had collected the amounts supporting that revenue before the current reporting period. It subsequently recognized the revenue as it delivered membership services.

The $78.7 million represented approximately 32.7% of reported membership revenue. But the remaining $161.8 million cannot be interpreted as new consumer cash collected during the period.

An annual subscription purchased during the period can produce both revenue recognized during that same period and deferred revenue remaining at the end. One payment can therefore appear partly in current revenue and partly in ending deferred revenue. This is why the $78.7 million and the $137.3 million cannot both simply be subtracted from the $240.5 million.

Deferred revenue increased sharply

Deferred revenue grew approximately 56% during fiscal 2025 and another 59% during the following nine months.

Oura recognized $78.7 million from the opening deferred balance, yet the balance still grew by approximately $50.8 million. Oura was therefore obtaining new advance payments faster than deferred revenue was being released into income.

This is consistent with a rapidly growing subscription business and with the increasing use of annual plans. Oura states that approximately 63% of new members began with an annual plan.

But “63% of new members” does not disclose the annual-versus-monthly mix of the entire membership base, the number of partner-funded members, partner pricing, bulk purchases, minimum commitments, or how much of the deferred balance came from individuals rather than institutions.

What does the deferred-revenue roll-forward suggest?

A simplified equation is:

Rearranging the equation:

Using Oura’s disclosed figures:

Subject to foreign exchange, acquisitions, non-membership deferred items and other classifications, Oura appears to have generated approximately $291 million in subscription-related billings or advance-payment activity during the nine-month period.

The statements do not suggest that Oura collected only a small amount of membership cash. They suggest the opposite. The unresolved question is whether that cash came from millions of individual consumers independently renewing—or from employers, insurers, enterprises and other partners paying on their behalf.

Could $137.3 million be ordinary consumer prepayments?

The balance is not mathematically impossible to explain through annual consumer subscriptions.

If 63% of five million members were annual members, that would equal approximately 3.15 million people. If their subscriptions were distributed evenly through the subscription year, the average unearned balance would be approximately half the $69.99 annual price, or roughly $35 per member. That alone would produce approximately $110 million. Monthly plans could add several million more.

This rough calculation brings ordinary consumer deferred revenue reasonably close to $137.3 million. But it does not prove the source. The 63% figure applies only to new members, Oura operates in 56 markets, pricing differs, membership revenue includes certain extended warranties, and partner arrangements can have different economics.

Five million members do not reconcile cleanly to the U.S. price

A simple straight-line average between quarter-end figures produces approximately 35.85 million member-months. Dividing $240.5 million by those estimated member-months produces approximately $6.71 of recognized membership revenue per member per month.

That is higher than both the $5.99 U.S. monthly price and the $5.83 monthly equivalent of the annual plan.

Rounded membership counts, intra-quarter growth, international pricing, partner economics, foreign currency and extended-warranty revenue may explain the difference. But the calculation demonstrates why Oura should disclose recognized membership revenue per average paying member.

Oura confirms that partners pay for some members

Oura states that a portion of its membership base is supported through partner programs in which a partner pays on behalf of eligible users. It then warns that if the partner stops paying, many users may not convert to individually paid memberships.

Yet Oura does not disclose the number of partner-funded members, their percentage of Paid Members, revenue paid by partners, partner-funded deferred revenue, average revenue per sponsored member, partner contract duration, or the conversion rate from partner-funded to self-paid membership.

Consumer-funded membership and sponsored membership both produce legitimate revenue. But they do not demonstrate the same demand, pricing power, retention or lifetime value.

Oura’s channel disclosure does not solve the problem

Wholesale includes both retail and enterprise partners, while both channel figures combine hardware and membership revenue. Oura does not provide the cross-tabulation required to determine how much of the $240.5 million was paid by individuals.

Oura also elected not to disclose remaining performance obligations for contracts expected to last one year or less. That is permitted accounting treatment, but it eliminates another route by which investors might identify significant annual partner commitments.

The receivables warning: Oura nearly doubled the money owed to it

When I examine a company approaching an IPO, I look for accounts that move abnormally—and then ask what business decision produced that movement.

Accounts receivable is money Oura has recorded as revenue but has not yet collected. The increase does not mean Oura shipped twice its annual production without payment. It means the amount customers owed Oura at the reporting date was nearly twice what they owed nine months earlier.

That is still significant because the receivable balance grew faster than several underlying measures:

The comparison is not exact because accounts receivable is a balance on one date while sales cover a period. Nevertheless, the movement deserves examination.

Who owes Oura this money?

Oura states that receivables primarily represent amounts due from retail customers, generally collected within 60 days without interest.

This is not principally millions of consumers failing to pay $5.99. It is largely money owed by retailers.

Oura recognizes hardware revenue when control transfers—generally upon delivery or when title and risk of loss pass. In the wholesale channel, “the customer” can be the retailer. The ring does not necessarily have to be sold to the final consumer before Oura recognizes revenue.

The S-1 reports Oura’s recognized sales to its customers. It does not disclose retail sell-through or the unsold Oura inventory held by retailers.

Why the timing deserves attention

Oura launched Ring 5 in June 2026—the final month of the reporting period—and reported one million Rings Sold during the quarter ended June 30.

If Oura delivered substantial Ring 5 inventory to retailers in June on 30- or 60-day terms, it could recognize revenue before June 30 and collect cash later. That is normal wholesale accounting when the retailer has taken control.

But immediately before an IPO, a sharp increase in wholesale shipments and receivables deserves scrutiny because retailer deliveries can improve reported revenue before consumer sell-through occurs.

The 63% prepayment figure does not answer the question

The 63% figure concerns new members choosing annual billing. It does not mean 63% of hardware customers prepaid for rings or that 63% of all revenue was collected in advance.

Oura can therefore have growing subscription prepayments and growing unpaid retail receivables simultaneously. The problem is not an accounting contradiction; it is that the S-1 combines distinct cash cycles without giving investors enough channel detail to evaluate them.

The return reserve also doubled

Rapid sales naturally produce larger return and warranty reserves. This does not prove retailer overstocking. Nevertheless, receivables nearly doubled, the sales-return liability more than doubled, wholesale revenue rose 77%, a new ring launched in the last reporting month, and retailer sell-through is not disclosed.

Receivables were already highly concentrated

At September 30, 2025, four unnamed customers represented approximately 83% of Oura’s receivables:

The filing does not provide an equivalent concentration table for the $157.4 million June balance. Investors cannot determine which retailers accounted for the increase, whether they paid after June 30, how much inventory they held, whether payment terms or return rights changed, or whether the increase represented ordinary launch inventory or an aggressive year-end shipment program.

The S-1 does not establish channel stuffing or improper revenue acceleration. It shows that immediately before the IPO, receivables and sales-return liabilities grew faster than the underlying hardware business. That abnormal movement deserves an explanation.

Operating cash flow requires its own dissection

Oura reported $328.0 million of operating cash flow compared with $60.8 million of net income. Approximately $238.9 million of operating cash came from working-capital movements:

The $328 million is valid operating cash flow. But much of it came from timing: reducing inventory, obtaining advance payments and deposits, carrying larger liabilities, and paying certain obligations later. These benefits can reverse when growth slows or obligations are paid.

Oura’s cash balances do reconcile

Combined unrestricted and restricted cash fell from approximately $860.5 million at September 30, 2025 to $371.8 million at June 30, 2026—a decline of approximately $488.8 million.

The cash position is not irreconcilable. The more consequential question is what Oura did with the money.

The billion-dollar question: Why did shareholders cash out before the IPO?

This is the most striking financial event disclosed in the S-1.

It was not merely a normal secondary transaction in which a new investor purchased shares from an existing investor. Oura itself used corporate cash to repurchase and retire the shares.

In a normal secondary sale, the buyer pays the seller and the company spends nothing. Here, Oura paid the selling shareholders, corporate cash left the company, the shares were retired, and the remaining holders’ percentage ownership increased.

The latest nine-month period included approximately $1.092 billion of preferred-stock repurchases and $79.5 million of common-stock repurchases. Oura repurchased approximately 27.9 million preferred shares and 1.6 million common shares.

One February 2026 tender offer cost approximately $534.2 million. Another $96.4 million settled a forward-equity arrangement and acquired approximately 5.4 million preferred shares.

These were not modest accommodations to a few employees needing liquidity. They were major balance-sheet transactions.

Put $1.173 billion in perspective

The amount spent repurchasing shares during the latest nine-month period equaled approximately:

• 97% of Oura’s entire $1.2145 billion of revenue;
• Nearly five times membership revenue;
• More than 19 times net income;
• More than three times ending cash; and
• More than three-and-a-half times operating cash flow.

Where did the repurchase money come from?

During fiscal 2025, Oura raised approximately $1.106 billion through preferred stock, borrowed approximately $198.5 million and spent $308 million repurchasing shares.

During the following nine months, it raised another $62.3 million through preferred stock, borrowed approximately $373.9 million and spent approximately $1.173 billion repurchasing shares.

Its revolving-credit balance increased from zero to $375 million. Total debt grew from approximately $3.2 million to $380.1 million. Combined cash and restricted cash fell from $860.5 million to $371.8 million.

Cash is fungible, so the filing does not permit us to say that a particular borrowed dollar went to a particular seller. The economic result is nevertheless clear: Oura used accumulated cash, new capital, operating cash flow and an expanded borrowing position while paying approximately $1.17 billion to existing shareholders.

The revolving facility expanded from $250 million to $500 million in January 2026 and then to $525 million in June. It is scheduled to increase automatically to as much as $770 million upon a qualifying IPO.

Why sell immediately before an IPO?

Having participated in numerous pre-IPO situations, I find this timing remarkable.

If an IPO is approaching and future prospects are exceptional, existing investors ordinarily have reasons to wait: public price discovery, liquidity, visibility and the possibility of further appreciation.

Yet certain Oura shareholders chose to sell before public price discovery. The filing does not identify all sellers, explain their motivations, or disclose what percentage of each seller’s position was liquidated. It would therefore be unjustified to state as fact that they had lost confidence.

There may be ordinary explanations: fund maturity, return of capital to limited partners, personal diversification, employee liquidity, reduction of post-IPO selling pressure, or a company belief that the stock was being repurchased below its future public value.

But scale changes the significance.

Did the sellers know something public investors do not?

Private-company investors inevitably possess information and access that future public investors do not yet possess. They may have seen internal statements, forecasts, partner concentration, renewal behavior, product-return trends, warranty trends, membership composition and contemplated IPO valuation.

That does not prove their information motivated them to sell. But their willingness to accept large-scale pre-IPO liquidity is itself economically relevant information.

An investor selling a modest portion of a long-held position is ordinary diversification. A company spending approximately $1.48 billion to provide private liquidity shortly before an IPO is not ordinary in scale.

The S-1 should explain who sold, how much each seller sold, what percentage of each holding was liquidated, whether sellers were founders, directors, officers or 5% holders, why Oura rather than incoming secondary buyers funded the transactions, how the board assessed the company’s interests, whether the repurchases were connected to IPO timing, and whether IPO proceeds will effectively replenish the funds used.

Was Oura buying cheaply—or were investors selling wisely?

Repurchase prices during the latest period ranged from approximately $25.81 to $56.12 per share. Without the IPO price, fully diluted capitalization and precise rights of each preferred series, outsiders cannot determine whether those prices represented a discount to anticipated public value, a premium for immediate liquidity, fair value, cap-table consolidation, or the price required to persuade particular holders to sell.

Oura may eventually argue that buying below the expected IPO valuation was accretive. That is possible.

But if the shares were clearly worth substantially more, why were sophisticated investors willing to sell such large positions before the IPO?

The public investor arrives after private investors were paid

1. Private investors funded Oura.
2. Oura grew rapidly.
3. New private capital entered at higher valuations.
4. Oura borrowed $375 million under its revolving facility.
5. Oura paid approximately $1.48 billion to repurchase shares.
6. Cash declined and debt increased.
7. Oura then filed to sell shares to the public.

The public investor is not entering at the same point as the early investor. Early holders have already been offered substantial liquidity without waiting for the IPO. The public investor arrives after the company’s own balance sheet absorbed the cost.

If Oura’s post-IPO prospects justify the valuation presented to public investors, why did sophisticated existing shareholders sell approximately $1.48 billion of stock before public price discovery—and why did Oura use its own balance sheet to purchase it?

There may be a satisfactory answer. It is not provided in the S-1.

What the S-1 establishes

1. Oura has a real and rapidly growing hardware business.
2. Oura has a substantial, high-margin membership business.
3. Oura receives significant and rapidly growing advance payments.
4. Some memberships are funded by partners rather than users.
5. Operating cash benefited materially from working-capital timing.
6. Receivables and sales-return liabilities nearly doubled before the IPO.
7. Receivables are principally owed by retailers and were highly concentrated.
8. Oura spent approximately $1.48 billion repurchasing shares across fiscal 2025 and the following nine months.

What the S-1 does not establish

1. How much membership revenue was paid directly by individuals.
2. How much was paid by employers, insurers, health plans or other partners.
3. Who supplied the $137.3 million of deferred revenue.
4. How many Paid Members personally paid Oura.
5. Retail sell-through or retailer inventory at June 30.
6. Which customers produced the near-doubling of receivables.
7. Whether retailer terms, incentives or return rights changed before the IPO.
8. The identities and individual motivations of all shareholders who sold.
9. What percentage of each seller’s position was liquidated.
10. Why Oura chose to fund the liquidity itself.

The disclosures investors need

For the membership business, Oura should disclose members, recognized revenue, cash collected and ending deferred revenue by direct monthly consumer, direct annual consumer, employer, insurer, health plan, enterprise partner, free concession and failed-payment grace period.

For retail distribution, it should disclose receivable aging, subsequent collections, days sales outstanding by channel, retailer inventory, sell-in versus sell-through, customer concentration and changes in payment terms, rebates, return rights or sales incentives.

For share repurchases, it should disclose seller identities, amounts and percentages sold, board rationale, funding sources, valuation analysis, seller participation criteria, remaining holdings and the relationship between the repurchases and contemplated IPO proceeds.

The real conclusion

Oura’s membership revenue is not fictitious merely because part of it was previously deferred. The deferred balance is not inherently abnormal. The cash balances reconcile. The receivable increase does not by itself prove channel stuffing. And the share repurchases do not prove that selling investors lacked confidence.

But the movements are too large to dismiss.

Oura’s filing confirms partner-funded memberships while withholding the payer breakdown. It reports receivables and sales-return liabilities that nearly doubled without disclosing retailer sell-through. And it reveals approximately $1.48 billion of company-funded liquidity for existing holders immediately before inviting public investors to participate.

Until those bridges are provided, two questions remain unanswered:

Who is actually paying Oura—and how many will continue paying when it is their own money?

Why did existing shareholders take approximately $1.48 billion out before the public was invited in?
