Oura files to go public, 5.5M rings sold

Oura has started the formal path toward a stock-market debut, but the first filing does not yet tell public investors what they most want to know: how much stock it plans to sell, at what price, and on what timetable. The company said May 21 that it confidentially submitted a draft registration statement on Form S-1 to the U.S. (finance.yahoo.com) Securities and Exchange Commission for a proposed initial public offering of common stock. That confidential filing matters because it moves Oura from private-market fundraising into the SEC review process, the stage that typically precedes a public prospectus. (businesswire.com) The company said the offering would proceed only after that review and would remain subject to market conditions. (finance.yahoo.com) The other number that stands out is 5.5 million. Oura said in September 2025 that it had sold more than 5.5 million rings since launch, with more than half of those sales coming in the prior year alone. ### What exactly did Oura file? Oura said it confidentially submitted a draft Form S-1, which is the registration document companies use to prepare for a U.S. (finance.yahoo.com) IPO. The company did not disclose the number of shares to be offered or a proposed price range. A May 22 TechCrunch report described the move as one of the notable IPO filings of the week and said the company had submitted the paperwork on Thursday. (finance.yahoo.com) CNBC also reported the filing on May 21, citing Oura’s announcement. ### Why does the 5.5 million figure matter? September 2025 is the point when Oura publicly tied its growth story to a concrete shipment number. In that announcement, the company said ring sales had passed 5.5 million and that more than half of those units were sold in the previous year. (businesswire.com) Tom Hale, Oura’s chief executive, said at the time that the company had sold more than 2.5 million rings since June 2024. (finance.yahoo.com) TechCrunch noted that the 5.5 million total was up from the 2.5 million figure Oura had reported the prior year. (techcrunch.com) ### How big is Oura before the IPO? Oura said in September 2025 that revenue topped $500 million in 2024 and that it was on track to reach $1 billion in sales in 2025. CNBC reported that Hale later told the network Oura could generate close to $2 billion in sales in 2026 as it invested in artificial intelligence and international expansion. (businesswire.com) October 2025 is the latest clear valuation marker surfaced in current reporting. CNBC said Oura was valued at $11 billion following a $900 million Series E round, while TechCrunch reported that September financing at $875 million and the same $11 billion valuation. (businesswire.com) ### What business is Oura taking public? Oura sells a ring-shaped wearable that tracks sleep, activity, readiness and other health metrics. The company said the ring tracks more than 50 health metrics continuously, while also stating that the product is not a medical device and is not intended to diagnose, treat, cure, monitor or prevent illnesses. San Francisco is Oura’s headquarters, and Oulu, Finland, is its European base, according to the company. (businesswire.com) Oura said it was founded in Finland in 2013, while TechCrunch described the ring product as having been founded in 2015, the year the product first launched. (cnbc.com) ### What should investors watch for next? The next public milestone is the eventual release of Oura’s full S-1 after SEC review. That document would typically include audited financial statements, risk factors, use of proceeds, share structure and details on growth, margins and losses. For now, Oura has said only that the IPO is expected to take place after the SEC completes its review process and that the number of shares and price range have not yet been determined.
