Company Overview - Oura Health Oy is nearing an $11 billion valuation after selling approximately 3 million Oura rings in the past year, raising $875 million in a Series E financing round that values the company at around $10.9 billion, doubling its previous valuation of $5 billion from the Series D round in November [1][2]. Financial Performance - The company has sold a total of 5.5 million rings, up from 2.5 million through June 2024, and is projected to generate over $1 billion in revenue in 2025, doubling the $500 million reported in 2024, with expectations to exceed $1.5 billion in sales in 2026 [4]. Growth Drivers - Recent growth has been driven by female shoppers, retail store sales, health savings account purchases, and international expansion, with the latest ring launched in Japan and Germany, and sales occurring in 4,000 stores [5]. Business Customers - The US military is the largest business customer, with tens of thousands of service members using the rings for fatigue tracking, although this revenue stream is a small contributor to overall sales [6]. Revenue Model - Oura's revenue model combines hardware and subscription services, with about 20% of revenue now coming from subscriptions, positioning the company differently from most hardware firms [7]. Product Development - The company launched the Oura Ring 4 last October and is planning annual hardware updates, while also considering new product form factors, although the ring will remain central to its strategy [8]. Competitive Landscape - Oura remains the dominant player in the fitness ring category, but faces increasing competition from companies like Samsung, which launched the Galaxy Ring, and various startups entering the market [9].
