Waystar Holding Corp., a provider of healthcare payments software, has announced a proposed public offering of 12,500,000 shares of its common stock. These shares are being offered by certain investment funds of EQT AB, Bain Capital, LP, and the Canada Pension Plan Investment Board, collectively referred to as the Selling Stockholders. The Selling Stockholders also plan to grant underwriters a 30-day option to purchase up to an additional 1,875,000 shares. Waystar itself is not selling any shares and will not receive proceeds from the sale. The offering will be managed by an underwriting group led by J.P. Morgan, Goldman Sachs & Co. LLC, and Barclays. A registration statement for the offering has been filed with the Securities and Exchange Commission but is not yet effective. Copies of the preliminary prospectus are available through the involved financial institutions.
