Oura files for a Nasdaq listing with revenue up 74% and 5 million subscribers

Oura, the Finnish maker of the smart ring of the same name, filed publicly for a United States initial public offering on 3 September and intends to list on Nasdaq under the ticker OURA. The filing discloses slightly more than $1.2 billion of revenue for the nine months to 30 June 2026, an increase of 74 percent on the same period a year earlier, with net income rising from roughly $1.5 million to close to $60.8 million. The number that explains the filing is not the revenue growth. It is the 5 million paying subscribers. Oura sells a ring and then charges a monthly fee for the software that interprets what the ring measures, and that structure is what separates it from every consumer hardware company that has tried and failed to reach public markets on device sales alone. The distinction matters because hardware businesses are punished by public investors for good reasons. Revenue is lumpy, tied to launch cycles and to whether this year's model is compelling. Margins are exposed to component costs and tariffs. Growth requires persuading someone to buy a physical object again. A device business with a large attached subscription behaves differently: a portion of revenue recurs whether or not the customer upgrades, gross margin on that portion is software margin, and the lifetime value of a customer stops being a single transaction. Oura's profit swing is the visible consequence. Going from about $1.5 million of net income to nearly $60.8 million over a comparable nine-month period, while revenue grew 74 percent, is the signature of operating leverage rather than of a hardware volume year. Subscription revenue scales without a proportional increase in cost of goods. The distribution figures fill in the rest. The company reports selling in 56 markets through roughly 8,400 physical stores, which for a category that began as a direct-to-consumer curiosity is a substantial retail footprint and an expensive one to build. Retail presence is how a wearable stops being an enthusiast product, and it is also a commitment to inventory, channel margin and returns that the direct model avoids. Reporting has put the raise at up to $3 billion and a target valuation near $16 billion, with Goldman Sachs, Morgan Stanley, J.P. Morgan, Allen and Company and BofA Securities named among the underwriters. Those figures come from press reports rather than from the company, and pricing on any listing moves until the day it does not, so they are best treated as indications. There are also numbers in the coverage that do not agree. Some accounts have cited annual revenue of around $1.4 billion alongside the $1.2 billion nine-month figure. Those are different periods rather than a contradiction, but they are being used interchangeably in places, and the disclosed nine-month figure is the one anchored to the filing. What the filing does not settle, and what any investor will focus on, is the durability of the subscription. Five million paying subscribers is a stock, not a flow. The questions are what proportion of ring buyers subscribe, what the monthly churn rate is, how many subscribers survive a ring's replacement cycle, and how much of the growth came from new device sales rather than from retaining existing members. A subscription attached to a physical device is only as durable as the device's place on the customer's finger. Competition is the other unresolved variable. Samsung has entered the smart ring category, and the wider wearables market is dominated by companies for whom health tracking is a feature of a device people already own. Oura's defence is that a ring is worn overnight in a way a watch often is not, and that its sleep and readiness analysis is the product rather than the sensor. Whether that holds as larger companies close the gap is the strategic question underneath the financial one. The next checkable milestone is the pricing range, which will show whether the reported $16 billion figure survives contact with the order book, and the first full set of quarterly disclosures after listing, which will show subscriber retention rather than subscriber count.
