SEI Investments Marks Leadership Transition: Alfred P. West, Jr. Elevated to Chairman Emeritus

**A Legacy Moment for SEIC**

SEI Investments Company (SEIC) made waves this week with a significant leadership restructuring that honors its founder while charting a new course for the firm. Alfred P. West, Jr., who built SEI from the ground up, is stepping into the prestigious role of Chairman Emeritus—a lifetime position that recognizes his foundational contributions to the company.

**What's Happening Behind the Scenes**

The planned transition takes effect on January 1, 2026, marking a deliberate and well-choreographed shift in company governance. West has decided to step away from his positions as director and board chair, creating space for fresh leadership to take the helm. Carl A. Guarino, an independent director on SEI's Board, will take over as the new Chairman, bringing his own perspective to guide the organization forward.

**Market Reaction and Trading Update**

The market seems cautious about the shake-up. In pre-market trading, SEIC shares were quoted at $82.93 on the Nasdaq, showing minimal movement with a slight dip of 0.05 percent. For investors watching SEIC, this leadership transition represents both continuity—through West's ongoing emeritus role—and evolution, with Guarino stepping in as the active chair.

**Why This Matters**

For a company like SEI Investments, founder transitions are more than just organizational shuffles. They signal confidence in succession planning and demonstrate how established firms can honor their legacy while adapting to future opportunities. With West remaining as Chairman Emeritus, the company maintains institutional memory while Guarino positions SEIC for what's next.
