WTW Investments and SEI Partner to Expand Private Markets Solutions for Defined Contribution Plans

Collaboration Aims to Broaden Access to Alternative Products in Retirement Ecosystem

OAKS, Pa., Aug. 4, 2026 /PRNewswire/ -- SEI^® (NASDAQ: SEIC) and WTW Investments, a global advisory, broking, and solutions company, today announced an expansion of their strategic relationship to support the development of private markets solutions for the 401(k) and broader U.S. defined contribution market.

Building on WTW's experience integrating private markets into defined contribution (DC) solutions since 2018, the relationship combines WTW's investment research and portfolio implementation capabilities with SEI's trust and platform capabilities through SEI Trust Company (STC), a leading provider of trustee, operational, and administrative services for collective investment trusts (CITs).

Together, the firms aim to help plan sponsors and participants gain access to more diversified sources of return through structures designed for the operational, governance and liquidity needs of the DC market. The collaboration also reflects growing demand for institutionalized structures that can help bring alternative investment strategies into defined contribution plans with the governance, oversight, and operational support required by the retirement market.

Commenting on the expanded partnership, Christy Loop, Head of U.S. Wealth and Strategic Initiatives at WTW, said:

"A key challenge for defined contribution plans is ensuring sponsors have the right wrapper, structure and terms to integrate diversifying exposures like private credit. By combining our strengths with SEI's expertise in designing fit for purpose vehicles for DC plans, we can expand participant access to private markets, enhancing diversification and providing differentiated sources of return to support long-term wealth accumulation."

WTW will provide investment and operational due diligence and research support for private markets strategies used in retirement-focused CIT and evergreen solutions. As part of the expanded relationship, WTW selected SEI Trust Company to support the delivery of certain WTW retirement solutions through CIT structures, reflecting the firms' broader collaboration across retirement and private markets initiatives.

The firms are also collaborating on the design of new products and structures intended to broaden access to private markets through vehicles suited to the needs of defined contribution plans. The expanded relationship reflects a shared commitment to product innovation and to helping the retirement market—including plan sponsors, consultants, and investment managers—evaluate how private markets exposures can be integrated into DC plans over time at scale and with appropriate risk management.

Sean Lawlor, Head of Public Markets for SEI's Investment Managers business, added:

"The ongoing convergence of public and private markets is fueling new opportunities for more diversified investment solutions through flexible, efficient CIT vehicles. With more than 30 years of experience as an independent CIT trustee, SEI's operational expertise complements WTW's investment acumen and supports the delivery of these strategies in a vehicle designed for scale, governance, and the evolving needs of the defined contribution ecosystem.

"Together, we're helping connect private markets innovation with retirement-focused solutions designed to support long-term participant outcomes."
