Business Description

Business Waystar Holding Corp. (“Waystar”, “we” or “our”) is a provider of mission-critical cloud technology to healthcare organizations. Our enterprise-grade platform transforms the complex and disparate processes comprising healthcare payments received by healthcare providers from payers and patients, from pre-service engagement through post-service remittance and reconciliation. Our platform enhances data integrity, eliminates manual tasks, and improves claim and billing accuracy, which results in better transparency, reduced labor costs, and faster, more accurate reimbursement and cash flow. The market for our solutions extends throughout the United States and includes Puerto Rico and other U.S. Territories. Risks and Uncertainties — We are subject to risks common to companies in similar industries, including, but not limited to, our operation in a highly competitive industry; our ability to retain our existing clients and attract new clients; our ability to successfully execute on our business strategies in order to grow; our ability to accurately assess the risks related to acquisitions and successfully integrate acquired businesses, including the acquisition of Iodine; our ability to establish and maintain strategic relationships; the growth and success of our clients and overall healthcare transaction volumes; consolidation in the healthcare industry; our selling cycle of variable length to secure new client agreements; our implementation cycle that is dependent on our clients’ timing and resources; our dependence on our senior management team and certain key employees, and our ability to attract and retain highly skilled employees; the accuracy of the estimates and assumptions we use to determine the size of our total addressable market; our ability to develop and market new solutions, or enhance our existing solutions, to respond to technological changes or evolving industry standards; the interoperability, connectivity, and integration of our solutions with our clients’ and their vendors’ networks and infrastructures; the performance and reliability of internet, mobile, and other infrastructure; the consequences if we cannot obtain, process, use, disclose, or distribute the highly regulated data we require to provide our solutions; our reliance on certain third-party vendors and providers. On occasion, we enter into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, we indemnify, hold harmless, and agree to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, in connection with any trade secret, copyright, patent, or other intellectual property infringement claim by any third party with respect to its technology. The terms of these indemnification agreements are generally perpetual any time after the execution of the agreement. The maximum potential future payments we could be required to make under these agreements is not determinable because it involves claims that may be made against us in the future but have not yet been made. Historically, we have not incurred costs to defend lawsuits or settle claims related to these indemnification agreements. We have entered into agreements with our directors or officers that may require us to indemnify them against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from their willful misconduct. No liability associated with such indemnifications was recorded as of December 31, 2025 and December 31, 2024. Reverse Stock Split On May 15, 2024, we effected a 0.605-for-1 reverse stock split of our common stock and a 0.605-for-1 reverse stock split of our Class A common stock. The reverse stock split did not result in an adjustment to the par value of common stock or Class A common stock. The reverse stock split was originally made effective on May 15, 2024 with a 0.62-for-1 ratio and this was retroactively amended on May 22, 2024 which updated the ratio to 0.605-for-1. All references in the accompanying consolidated financial statements and related Note 15, Note 17, and Note 19 have been updated to reflect the effects of the reverse stock split at the amended 0.605-for-1 ratio.…
