SAN FRANCISCO, September 4, 2026 — Oura has opened its hardware-and-membership economics to public-market scrutiny after filing a registration statement for a proposed initial public offering. The smart-ring company reported $1,214.5 million in revenue for the nine months ended June 30, up 74% from $697.6 million a year earlier.

The Form S-1 filed with the U.S. Securities and Exchange Commission is a proposal, not a completed flotation. It does not yet establish the number of shares, offer price, proceeds or market valuation. Those terms can change before an offering becomes effective.

Five million members change the value of a ring sale

Oura reported 5.0 million paid members as of June 30, 2026 and weighted-average 12-month paid-member retention of approximately 85%. The figures show why the company is more than a one-time device seller. A ring begins the customer relationship; recurring membership revenue continues while a subscriber finds the health insights useful.

The model still depends on physical products. Hardware represented 83% of fiscal 2025 revenue, while membership represented 17%. Oura must therefore manage design, components, inventory, retail distribution and returns at the same time as cloud software, data science and subscription engagement.

The filing exposes five operating measures

  • $1,214.5 million of revenue in the first nine months of fiscal 2026;
  • 74% revenue growth from the comparable 2025 period;
  • 5.0 million paid members at June 30;
  • approximately 85% weighted-average 12-month paid-member retention;
  • $60.8 million of net income for the nine-month period.

Growth arrived with improving margins

Gross margin rose to 55% for the nine months ended June 30 from 51% in the prior-year period. Net income increased to $60.8 million from $1.6 million. These figures distinguish Oura from consumer-device businesses that expand rapidly while moving further from profitability.

The improvement needs context. Hardware launches, channel mix, component costs and marketing can move margins between periods. Membership carries different economics from ring sales, so the mix will matter as the installed base grows. Investors will watch whether retention and product demand remain strong without disproportionate acquisition spending.

Ring 4 accelerated the hardware base

Oura said fiscal 2025 hardware revenue increased 126%, driven mainly by rings sold rising from 1.0 million to 2.3 million after the October 2024 launch of Oura Ring 4 and expansion of wholesale distribution. Membership revenue increased 110% as paid members rose from 1.3 million to 2.9 million over that fiscal year.

A successful generation can produce a sharp step in sales, but wearable businesses must sustain demand between launches. Comfort, battery life, measurement consistency and useful software updates influence whether customers keep wearing the product and eventually replace it.

Wellness guidance is not the same as diagnosis

The ring measures physiological signals and turns them into sleep, activity, readiness and other insights. Such feedback can help a member observe patterns, but it does not automatically establish a medical diagnosis. Product claims must remain aligned with evidence and any applicable regulatory authorisation.

Health data also creates privacy obligations. Oura must explain collection, retention, sharing and deletion, protect accounts and infrastructure, and manage partners that receive authorised information. Trust is a direct commercial input when users wear a sensor continuously.

Finnish origins meet the American public market

Oura traces its origins to Finland, where its founders began developing the ring, while the S-1 registrant is headquartered in San Francisco in the United States. The history joins Nordic wearable engineering with the scale of American consumer technology and capital markets.

The proposed IPO will test whether investors value that combination as a durable platform or primarily as a fast-growing device cycle. The answer will depend on member retention, hardware replacement, data trust and sustained profitability rather than the ring's small physical size.

An IPO filing begins diligence

The Economist profile describes how the product reached millions of users. The filing adds the financial evidence needed to judge the business behind that adoption.

Oura has not completed an offering merely by submitting the S-1. Pricing, dilution, use of proceeds and market conditions remain open. What is now clear is the operating proposition: recover acquisition cost through hardware, retain members through useful insights and reinvest the combined economics in the next product cycle.
