Stratos Completes Acquisition of 11 Partner Practices Totaling Approximately $4.8 Billion in Client Assets

BEACHWOOD, Ohio -- May 14, 2026 – Stratos Wealth Holdings (“Stratos”) today announced it has completed the acquisition of 11 partner practices ranging from sole practitioners to multi-advisor teams, representing approximately $4.8 billion in total client assets, as of December 31, 2025. These transactions were in progress prior to SEI’s strategic investment in the Stratos business[1] and reflect Stratos’ focus on strategic investments in partner advisory practices to support growth initiatives, enhance enterprise value, and establish a clear path for succession.

Stratos has pursued these acquisitions in response to a growing need among advisory practices for a more structured and scalable approach to long-term growth and transition planning. Rather than relying solely on traditional succession models, Stratos partners with advisors through aligned investments, providing access to expanded resources and operational support while enabling advisors to continue leading their practices with long-term strategic alignment.

“Advisors today are navigating increasing complexity, from evolving client expectations to technology demands and long-term continuity planning,” said Jeff Concepcion, founder and CEO of Stratos. “We believe the traditional succession model is evolving, and advisors are increasingly looking for strategic partners that can provide scale, resources, and flexibility without sacrificing leadership of their businesses. SEI’s strategic investment has helped accelerate our ability to support advisors while preserving the entrepreneurial culture that defines Stratos.”

The 11 partner practices represent a diverse cross-section of the advisory landscape, including individual practitioners and multi-advisor teams. Each practice entered into a structured partnership with Stratos aligned around shared growth objectives, operational scale, and long-term planning.
