A sharp rise in U.S. borrowing costs has closed the IPO window on one of the most closely watched listings in wearable health tech, and Oura is unlikely to be the last issuer to step back.

Oura postponed its Nasdaq offering on Sept. 29, eight days after formally launching it. The smart ring maker had planned to sell 50 million shares at $40 to $44 each, raising up to $2.2 billion at an implied valuation of about $15 billion, according to BBC and CNBC. In a statement carried by CNBC, Oura pointed to market uncertainty and said demand remained strong. CEO Tom Hale said the company has “the luxury of choosing our moment.”

Reuters attributed the wave of delays to surging bond yields and higher interest rates. The BBC reported that the yield on 10-year U.S. government debt this week reached its highest level since 2007. Other prospective issuers have also pulled listings in recent weeks, citing energy costs, military conflicts, trade tensions and inflation fears.

Samuel Kerr of Mergermarket told the BBC the market is now “very different” from weeks ago. He told CNBC that rising sovereign yields are leading some investors to demand wider discounts.

The numbers Oura carried into the process were strong: SGIE’s analysis of the filing cited GAAP net income of $60.8 million for the nine months to June 30, while Oura told CNBC it expects 90 percent revenue growth in fiscal 2026. A consumer class action filed in August challenges the accuracy of Oura’s sleep tracking. The company says it stands behind its science, and the BBC reported that the delay is understood to be unrelated. SGIE’s analysis framed the suit as an early test of the valuation’s health-data case.

The SGIE take

Oura asked investors to price subscriptions and data rather than rings. That kind of valuation is sensitive to discount rates, the pressure Kerr described. Until a listing prices, wearable peers lack a public benchmark.
