SEI Investments Transitions Leadership as Founder Steps Down

SEI Investments Company announces a pivotal leadership transition as Alfred P. West, Jr., the company's founder and Executive Chairman, resigns from his position as director and board chair effective January 1, 2026. After founding SEI in 1968 and leading it for 54 years, West’s resignation marks the end of an era for the company. His tenure has been characterized by the transformation of SEI from a modest financial technology startup into a global powerhouse managing approximately $1.8 trillion in assets and generating over $2.1 billion in annual revenues. This leadership change signals a significant shift for SEI, as the company prepares to embrace new strategies under the guidance of a new chairman.

Carl A. Guarino, an independent director at SEI, is appointed as the new Chairman of the Board, succeeding West. Guarino's ascension to this leadership role comes at a time when SEI seeks to build on its existing strengths while navigating the rapidly evolving financial technology landscape. CEO Ryan Hicke commends West’s visionary leadership and collaborative approach, which have been instrumental in shaping SEI into a global leader. Hicke expresses confidence in Guarino's ability to continue this legacy, noting his proven leadership experience within the industry. This transition not only reinforces SEI’s commitment to innovation but also underscores the importance of adaptive leadership in maintaining competitive advantage.

As West steps back from day-to-day operations, he takes on the honorary title of Chairman Emeritus, remaining a close advisor and mentor to the team. The Board and SEI's employees express deep gratitude for West's lifelong dedication and leadership, recognizing the solid foundation he has built over decades. This transition comes with the promise of continued growth and evolution for SEI, as the company aims to leverage its established reputation in financial services while exploring new avenues for development in the digital age. The leadership change is poised to enhance SEI's trajectory as it seeks to address emerging challenges and capitalize on new opportunities in the financial technology sector.

In addition to the leadership transition, SEI continues to focus on its core mission of transforming the financial services industry through technology and innovation. The company remains committed to fostering a culture of collaboration and excellence as it adapts to the evolving demands of its clients and the marketplace.

With West's legacy firmly in place, SEI stands ready to embark on this new chapter, reinforcing its position as a leader in the financial technology space while honoring the vision that has guided its journey for over five decades.
