The System Rebuilds: Why the Transamerica-GLA Deal is a Blueprint

BALTIMORE, MD – September 03, 2026 – On the surface, the announcement that Transamerica Asset Management (TAM) is expanding its partnership with Great Lakes Advisors (GLA) seems like standard industry news. The deal brings GLA’s established Large Cap Value strategy to TAM’s vast network of financial advisors through separately managed accounts (SMAs) and unified managed accounts (UMAs). But to view this as merely a new product on a shelf is to miss the larger story. This collaboration is a clear signal of a fundamental restructuring in the wealth management industry—a systemic shift away from selling products and toward delivering integrated, personalized platforms.

This partnership leverages the core strengths of both organizations: Transamerica's immense distribution scale and advisor relationships, and GLA's specialized investment expertise. The strategy will be accessible on key wealth management platforms, including LPL Financial, Charles Schwab, Morgan Stanley, and Envestnet, ensuring it reaches the advisors who build portfolios for millions of Americans. While the immediate goal is growth for both firms, the underlying mechanics reveal how the infrastructure of investing is being rebuilt from the ground up to serve a new era of client expectations.

The Quiet Surge of Managed Accounts

The Transamerica-GLA partnership is timed to perfection, landing in the middle of a massive, yet often underreported, boom in managed accounts. This isn't a gentle wave; it's a tsunami of assets moving toward more customized structures. Industry research shows that managed account assets soared to $13.7 trillion in 2024, a nearly 20% jump from the prior year. Projections forecast this figure could swell to an astounding $31.8 trillion by 2028.

The engines of this growth are the very vehicles at the heart of this deal: SMAs and UMAs. These formats have seen blistering compound annual growth rates of over 18% in the last five years. The reason is simple: they are the ideal architecture for the modern investor. Unlike a traditional mutual fund, an SMA gives an investor direct ownership of the underlying securities. This seemingly small distinction unlocks a world of possibilities, most notably in tax management. Advisors can engage in sophisticated tax-loss harvesting on behalf of individual clients, a level of personalization previously reserved for the ultra-wealthy.

UMAs take this a step further, allowing an advisor to consolidate multiple strategies—SMAs, mutual funds, ETFs, and individual securities—into a single, streamlined account. This simplifies reporting, reduces paperwork, and provides a holistic view of a client's portfolio. The demand for this efficiency and customization is so strong that industry analysts predict UMAs are on track to become the largest platform type in the advisory market, overtaking more traditional models. As one analyst noted, firms that fail to offer advanced tax management capabilities within these structures will face a significant competitive disadvantage in the coming years.

A Symbiotic Partnership in a Crowded Field

In a crowded marketplace dominated by giants like BlackRock—whose managed accounts business surpassed $300 billion in assets last year—differentiation is paramount. The TAM-GLA deal is a classic example of a symbiotic strategy designed to cut through the noise. Transamerica, a subsidiary of the global financial services group Aegon Ltd., brings a powerful distribution engine. It provides the rails on which investment strategies can travel to a vast network of financial advisors. However, a powerful engine needs high-quality fuel.

This is where Great Lakes Advisors, a subsidiary of Wintrust Financial Corporation, comes in. GLA provides the specialized investment acumen with its "established Large Cap Value strategy." For GLA, the partnership is a gateway to exponential growth, allowing it to tap into the intermediary channels that are difficult to access for a more specialized firm. For Transamerica, it enriches its platform, making it a more compelling one-stop shop for advisors seeking a diverse toolkit.

"At TAM, our vision is to connect the right solutions to our clients' needs, and this GLA partnership extension reflects that commitment," said Marijn Smit, CEO of Transamerica Asset Management, in the official announcement. His counterpart at Great Lakes Advisors, CEO Tom Kiley, highlighted the strategy's role as a diversifier, stating, "In an environment where equity allocations have grown increasingly concentrated, we believe disciplined large cap value exposure is an essential diversifier for advisors and their clients." These statements are not just corporate rhetoric; they articulate the core logic of the platform model: combining broad access with specialized expertise.

Empowering the Modern Advisor

The ultimate beneficiary of this systemic shift is the financial advisor and, by extension, their client. The modern advisor's role has evolved from a stock picker to a holistic financial architect. Their value lies in understanding a client's complete financial picture—from retirement goals and risk tolerance to tax circumstances and legacy aspirations. To do this effectively, they need tools that are flexible, efficient, and powerful.

The availability of GLA’s strategy within a UMA or SMA structure on the TAM platform provides precisely that. It gives advisors a rigorously managed, value-oriented equity strategy that they can then tailor to individual client needs. This could mean excluding certain stocks for ethical reasons or strategically harvesting losses to offset gains elsewhere in the portfolio. This level of control is critical in serving the next generation of investors, particularly as the "Great Wealth Transfer" moves an estimated $84 trillion to younger cohorts who demand greater personalization and transparency.

Furthermore, the integration with major platforms like Envestnet and Schwab is non-negotiable for adoption. Advisors operate within complex technological ecosystems; a new solution, no matter how good, must fit seamlessly into their existing workflow. By ensuring this integration from day one, Transamerica and Great Lakes Advisors are not just launching a product—they are delivering a practical solution designed for immediate use. This focus on the advisor's reality is a hallmark of the new platform-centric approach to asset management.

This partnership is far more than a simple business agreement. It is a case study in the ongoing reconstruction of the investment management industry. The old model of siloed, one-size-fits-all products is being dismantled and replaced by integrated, open-architecture platforms that prioritize advisor efficiency and client personalization. Technology is the catalyst, enabling a level of mass customization that is redefining what it means to manage wealth. This model, where distribution networks partner with specialist managers on integrated platforms, is becoming the new blueprint for asset management in an increasingly complex and client-centric world.
