Waystar Holding ^{Filed, US Offering, Nasdaq: WAY}

Waystar provides healthcare organizations with mission-critical cloud software that simplifies healthcare payments. Our enterprise-grade platform streamlines the complex and disparate processes our healthcare provider clients must manage to be reimbursed correctly, while improving the payments experience for providers, patients, and payers. We leverage internally developed artificial intelligence (“AI”) as well as proprietary, advanced algorithms to automate payment-related workflow tasks and drive continuous improvement, which enhances claim and billing accuracy, enriches data integrity, and reduces labor costs for providers. Our software is used daily by providers of all types and sizes across the continuum of care, including physician practices, clinics, surgical centers, and laboratories, as well as large hospitals and health systems. We currently serve approximately 30,000 clients of various sizes, representing approximately one million distinct providers practicing across a variety of care sites, including 18 of the top 22 U.S. News Best Hospitals. Our client base is highly diversified, and for the six months ended June 30, 2023 and the year ended December 31, 2022, our top 10 clients accounted for only 11.7% and 11.4%, respectively, of our total revenue.
