SEI-Eclipse Holding Company, LLC, a newly formed entity, purchased the U.S.-based Stratos business for approximately $441 million, representing approximately 81% of the total transaction value. As previously announced, Founder and CEO Jeff Concepcion will continue to lead the Stratos business, which will operate under its brand and as an affiliated business of SEI. Stratos’ client service model, including custodial relationships, will continue, and its current offerings will be reinforced by SEI’s capabilities across technology, custody, operations, and asset management. Commenting on the partnership, CEO Ryan Hicke said: “There are three core growth opportunities in wealth management: advice, asset management, and administration. We’ve built world-class administration and asset management platforms that enable the more effective delivery and execution of advice, and Stratos further enhances our ecosystem with an advice platform that respects advisor independence and capitalizes on trends in fee-based wealth management. “We believe in the value of advice, and by combining our strengths in all three areas and fostering mutual learning across them, we can enhance the solutions and services we provide across all intermediaries, help them scale their businesses, and drive powerful, sustainable growth.” Press release.

The breadth and strength of SEI’s capabilities, including alternative investments and OCIO services, will enhance our ability to deliver on that commitment while scaling our own operations. “SEI’s evolution over the last few years has been remarkable, and its ecosystem powers its clients’ transformation. We’re thrilled to have a partner investing in this next step of our growth journey, so we can help advisors serve their clients more seamlessly and position their businesses for future success.” Based in Beachwood, OH, Stratos includes a national network of more than 350 experienced financial advisors and financial planning practitioners working across 29 states throughout the United States.
