Oura Has a Subscription Business, but Hardware Still Sets the Economics
Executive summary
Oura's September 3 IPO filing presents an unusually attractive consumer subscription profile: 5.0 million paid members, approximately 85% weighted-average 12-month retention, and an 89% membership gross margin for the nine months ended June 30, 2026. Membership revenue more than doubled year over year.
The conventional interpretation is that the ring is becoming a distribution vehicle for a software-like recurring-revenue business. That is directionally right and economically incomplete.
Membership produced only 20% of revenue in the latest nine-month period. Hardware still produced the other 80%, supplied nearly every new member, offset customer-acquisition cost at purchase and determined whether the subscription remained useful. Historically, more than 94% of activated rings convert to paid membership, which is impressive, but it also reveals the dependency: paid-member growth has largely scaled with rings sold. The subscription does not yet have an independent acquisition engine.
The contrarian thesis is that Oura should be valued and operated as a hardware-gated membership system, not as software revenue attached to a disposable device. Product reliability, replacement cycles, channel economics and the cost of putting another ring on another finger still set the consolidated outcome. An $84.4 million increase in fiscal 2025 warranty expense tied to battery issues demonstrates how quickly a physical-product problem can overwhelm the elegance of an 89%-margin membership stream.
This thesis is falsifiable. It weakens if membership becomes materially larger than 20% of revenue, if paid-member growth separates from ring shipments, if durable cross-device access emerges, or if warranty and hardware-acquisition costs become immaterial to consolidated margin. The current filing shows none of those conditions yet.
Market context
Oura filed its Form S-1 with the SEC on September 3, 2026 and applied to list on Nasdaq under the ticker OURA. Reuters and TechCrunch both led with the scale and speed of the business. The numbers justify the attention.
Revenue rose from $406.8 million in fiscal 2024 to $907.9 million in fiscal 2025. For the nine months ended June 30, 2026, revenue reached $1.2145 billion, up 74% from $697.6 million in the comparable period. Paid members doubled from 2.5 million to 5.0 million, while rings sold rose from 1.8 million to 3.1 million. Oura reported $60.8 million of net income and $106.7 million of adjusted EBITDA in the latest nine-month period.
The strategic appeal is familiar. Hardware creates a proprietary data stream. Software turns that stream into scores, trends and recommendations. A recurring membership monetizes the continuing interpretation layer. Oura describes the membership as central to unlocking the hardware's full value, and says hardware gross profit offsets acquisition cost at the point of purchase.
That last point deserves more attention than the subscription multiple. A business whose customer-acquisition spend is recovered through hardware gross profit is better than a hardware business that subsidizes every device. But it remains different from a software service that can acquire and serve a new subscriber without manufacturing, shipping and supporting a physical unit.

Findings
Finding 1
The membership engine is strong, but its acquisition loop is still a hardware loop.
Oura's membership revenue grew 121% to $240.5 million in the first nine months of fiscal 2026. The company says approximately 63% of new members began on an annual plan, nearly all paid members are monthly active users, and daily active users represented about 65% of monthly active users. Weighted-average 12-month paid-member retention was approximately 85% as of June 30.
Those are high-quality subscription signals. Annual plans improve cash timing and reduce monthly cancellation opportunities. Frequent engagement suggests the service is functioning as a daily utility rather than an insurance-like subscription that consumers forget. An 89% membership gross margin gives Oura room to invest in features, support and retention.
But the conversion funnel begins with a ring. Oura says historically more than 94% of ring activations convert to paid membership and explicitly states that paid-member growth has largely scaled with rings sold. Paid members grew 100% year over year as rings sold grew 75% in the latest nine-month comparison. Membership growth lags hardware growth because a new ring must be sold and activated before the paid period begins.
This changes how operators should interpret the flywheel. The most important top-of-funnel metric is not app downloads, free trials or even subscription starts in isolation. It is economically acquired, activated and functioning hardware. The membership can compound lifetime value after that event, but it cannot currently manufacture the event.
Oura's sales and marketing expense rose 84% to $257.9 million in the latest nine months, including a $72.8 million increase in paid media and other advertising tied partly to the Oura Ring 5 launch. Sales and marketing reached 21% of revenue, up from 20%. That does not invalidate the acquisition model: the company says hardware gross profit provides immediate payback. It does show that paid-member growth is neither costless nor purely viral.
The practical implication is a cohort-level unit economics requirement. Oura and similar businesses need to connect media spend, retail commissions, device gross profit, activation, trial conversion, annual-plan mix, retention, replacements and support cost in one ledger. A subscription dashboard that starts at activation will miss the cost and operational risk that made activation possible.
Finding 2
Hardware quality is a retention input and a margin variable, not a separate product issue.
Oura's fiscal 2025 experience makes the dependency visible. Cost of revenue increased by $294.2 million from fiscal 2024. Within that change, warranty expense rose by $84.4 million because of elevated reserves for battery-performance issues affecting certain Oura Ring 4 cohorts. Consolidated gross margin fell from 65% to 52%.
The filing also says access to the membership depends on continued ring performance. Defects can therefore cause two losses: the direct cost of replacing or supporting the product and the downstream risk that a member disengages or cancels. A hardware failure interrupts data collection, and the absence of data reduces the software's value precisely when the company needs recurring engagement.
The latest period improved. Consolidated gross margin recovered from 51% to 55%, which Oura attributes mainly to lower warranty rates for earlier hardware cohorts and lower per-unit manufacturing costs. Yet warranty costs still increased by $28.6 million as volume grew. The issue is not whether the Ring 4 battery problem will repeat in exactly the same form. It is that each device generation introduces a fresh quality distribution into a recurring-revenue base.
That makes warranty management part of subscription operations. Operators should measure device survival, replacement incidence and time without usable data by activation cohort, firmware version, supplier lot, geography and acquisition channel. They should also track whether replacement recipients retain differently from unaffected members. A fast, generous replacement can protect retention; a slow resolution can turn a manufacturing defect into a subscription cancellation.
The accounting deserves care as well. Membership gross margin can remain high while consolidated margin deteriorates because warranty cost sits in the hardware layer that feeds and sustains the membership. Segmenting the margins is analytically useful. Treating them as economically independent is not.
Finding 3
The mix shift is real, but it has not yet changed the identity of the business.
Membership revenue increased from 15.6% to 19.8% of total revenue in the latest nine-month comparison. That is meaningful progress, especially because membership grew faster than hardware. But the full-year series shows that mix does not move in a straight line: membership was 18.6% of revenue in fiscal 2024 and 17.5% in fiscal 2025 as the Ring 4 launch accelerated hardware sales.
Product cycles can temporarily push the business away from the subscription profile investors expect. A successful launch raises hardware mix and acquisition spending before the resulting membership cohorts season. A weak launch reduces the inflow of new members. A quality problem raises warranty expense and can threaten existing engagement. These are not edge cases. They are the operating cadence of a hardware-gated membership model.
The annual-plan shift is helpful but introduces another measurement caution. Oura recognizes membership revenue over the subscription term, while cash arrives earlier for annual plans. Paid-member counts also include members in a grace period of up to 28 days after failed payment and limited free-membership concessions. None of those policies is unusual, but they mean member growth, cash collection and recognized revenue should not be treated as identical measures.
The stronger strategic path is not to pretend the hardware is disappearing. It is to make the gate more productive. That can mean longer device life, lower replacement cost, higher activation, better retail conversion, family or employer distribution, and software features that raise willingness to retain across device generations. The ring remains both the sensor and the sales channel.
Implications for operators
Consumer hardware companies adding subscriptions should resist importing a SaaS scorecard without adaptation. Monthly recurring revenue, annual-plan mix and retention belong on the dashboard, but so do activated-device acquisition cost, contribution margin after warranty, usable-device days and replacement-adjusted retention.
Pricing should recognize the two-part product. If hardware gross profit truly offsets acquisition cost, aggressive device discounting can damage the very payback mechanism that supports recurring economics. Promotions should be evaluated on total cohort contribution, not on rings shipped or membership starts. A discounted device that creates a low-retention member and a high warranty burden is not efficient acquisition.
Product planning should treat reliability investment as retention investment. The marginal engineering dollar that reduces battery failures may create value through fewer replacements, lower support load, more complete longitudinal data and higher renewal. Those benefits sit across departments, so a hardware-only return model will understate them.
Channel strategy also matters. Retail distribution can widen acquisition, but commissions, returns, education quality and activation rates may differ from direct sales. Because the membership begins after hardware activation, sell-through without activation can flatter hardware revenue while weakening the recurring funnel. Cohort reporting should follow the customer from channel to functioning device to paid renewal.
Finally, investors and boards should model the company as two interlocked systems. The hardware system creates sensing capacity, acquisition payback and operational volatility. The membership system creates retention, high incremental margin and lifetime value. The consolidated value depends on both systems working at the same time.
Risks & open questions
The alternative, more bullish interpretation may prove correct faster than this report assumes. Membership revenue grew 121%, paid members doubled, retention is high and 63% of new members chose annual plans. If those cohorts renew and hardware growth moderates, membership mix could rise quickly without any change in product architecture.
The S-1 also gives only a limited public history. Two full fiscal years and two nine-month comparisons are not enough to observe a complete device-replacement cycle or recession response. Oura's 85% retention metric is weighted by monthly cohort size and includes winbacks within the same 12-month period, so it should not be read as a simple beginning-to-ending subscriber count.
Health-plan, employer and clinical distribution could reduce reliance on consumer paid media. New services could also create revenue that is less tightly coupled to a single device. The filing describes broader health ambitions, but current revenue disclosure does not yet show a separate material engine.
Competition is another open question. Larger device ecosystems may bundle similar insights into hardware consumers already own, while specialized health services may compete for the same subscription budget. Oura's proprietary longitudinal data and form factor can differentiate it, but maintaining that advantage requires continued spending on research, software and new hardware.
The clearest falsification tests are observable: membership share rising materially above 20%; paid members growing faster than ring cohorts for a sustained period; sales and marketing falling as a share of revenue without slowing member growth; warranty expense becoming consistently immaterial; and retention holding through a full device-replacement cycle. Until then, the subscription should be treated as excellent economics built on a physical dependency.
Appendix / methodology notes
This report uses Oura's Form S-1 filed September 3, 2026 as the primary source. Financial values are taken from the prospectus summary and management discussion. Blackrock Research calculated membership share by dividing disclosed membership revenue by disclosed total revenue.
The analysis distinguishes period flows from period-end stocks. Revenue, rings sold, expenses and income cover a fiscal year or nine-month period. Paid members are measured at the end of the relevant period. Growth comparisons therefore describe related operating measures, not a direct conversion equation.
Oura defines a paid member as a member with activated paid service and a valid payment method, excluding an initial free trial. The count includes members in a grace period of up to 28 days following failed payment and some members receiving limited free periods as concessions. Weighted-average 12-month retention is calculated across monthly cohorts, weighted by cohort size, and includes winbacks within the same 12-month window.
Adjusted EBITDA is non-GAAP and should not be compared mechanically across companies. Warranty reserves depend on management estimates of future claims and costs. Historical warranty expense can move as those estimates and observed device performance change. The table is chart-ready but is not a forecast and contains no synthetic market data.
