ŌURA Officially Takes the Next Step Toward Wall Street: Files Public Form S-1 for Nasdaq IPO

The pioneer of smart ring technology is making its long-anticipated leap onto the public markets.

ŌURA, the health intelligence platform and maker of the Oura Ring, announced that it has filed a public registration statement on Form S-1 with the U.S. Securities and Exchange Commission (SEC) for a proposed initial public offering (IPO) of its common stock.

The company intends to list on the Nasdaq Global Select Market under the ticker symbol “OURA”.

The Road from Confidential Draft to Public S-1

ŌURA originally laid the groundwork for this milestone on May 21, 2026, when it confidentially submitted a draft Form S-1 with the SEC. By transitioning from a confidential submission to a formal, publicly available S-1 filing, the company is signaling that its listing process is moving into high gear.

Key offering details confirmed in the filing and announcement include:

• Offering Size & Pricing: The number of shares to be offered and the proposed price range have not yet been determined.
• Underwriting Syndicate: The offering is backed by a heavy-hitting roster of investment banks. Joint lead book-running managers include Goldman Sachs & Co. LLC, Morgan Stanley, J.P. Morgan, Allen & Company LLC, and Jefferies.
• Additional Book-Runners: BofA Securities, Barclays, Wells Fargo Securities, Citizens Capital Markets, KeyBanc Capital Markets, Guggenheim Securities, Canaccord Genuity, Needham & Company, Raymond James, Rothschild & Co, Truist Securities, and William Blair.
• Retail Co-Manager: Robinhood Securities will serve as a co-manager for the offering.

A Maturing Wearable & Health Platform

Founded in Finland in 2013, ŌURA has evolved from a niche sleep-tracking wearable into a comprehensive preventative health intelligence ecosystem. Headquartered in San Francisco with its European base in Oulu, Finland, the platform pairs hardware sensors with algorithmic metrics covering sleep, cardiovascular health, activity, metabolic wellness, stress, and readiness.

Recent market commentary and analysis surrounding the filing highlight several broader dynamics for investors to watch:

1. Market Valuation Expectations: Pre-IPO reports and market trackers have suggested ŌURA could seek to raise billions in fresh capital, with potential valuations reaching into the $16+ billion range.
2. Expansion Beyond Hardware: ŌURA’s hybrid model of hardware sales coupled with recurring software membership subscriptions positions it as a recurring-revenue digital health company rather than just a consumer electronics brand.
3. Competitive Landscape: As tech giants and new competitors increasingly target the smart ring form factor, the IPO proceeds are poised to provide ŌURA with substantial dry powder to defend its market-leading position and scale clinical partnerships.

What’s Next?

The registration statement filed with the SEC has not yet become effective, and the final timing, share pricing, and valuation will depend on market conditions and the completion of the SEC’s review process.
