Mesirow Acquires LeafHouse, Expands Retirement Platform

Mesirow, a prominent independent financial services firm, is significantly expanding its fiduciary capabilities through an agreement to acquire LeafHouse Financial Advisors. This strategic move is set to enhance Mesirow's existing Fiduciary Solutions division, a cornerstone of its retirement plan services for nearly two decades. The combined entity is projected to manage an impressive $138 billion in assets under management and advisement, a substantial increase from its previous $115.2 billion as of March 31, 2026. The transaction is anticipated to finalize in the third quarter of 2026, pending standard closing conditions.

This acquisition represents a key step in Mesirow's growth strategy, focusing on integrating businesses that align culturally and bolster its market position. LeafHouse Financial Advisors brings a robust distribution network and a highly adaptable approach to retirement plan services, which will complement Mesirow's established recordkeeper-integrated model. The integration aims to forge a hybrid platform capable of serving a broader spectrum of advisors, plan sponsors, and institutional partners with enhanced scale and technology-driven agility.

The deal also includes a strategic investment from Mesirow into LeafHouse Financial Services, the technology-focused arm of the LeafHouse business. While the advisory operations are being absorbed into Mesirow, LeafHouse Financial Services will continue to operate independently, concentrating on advancing its technology solutions for various financial industry stakeholders, including advisors, recordkeepers, and asset managers. This dual approach ensures continued innovation in technology alongside the expansion of advisory services.

Mesirow Fiduciary Solutions currently serves close to 10,000 financial advisors, offering outsourced ERISA fiduciary services, investment due diligence, reporting, and custom default solutions for retirement plans, HSAs, and IRAs. The addition of LeafHouse's expertise is expected to create a more versatile and comprehensive offering for participants across the retirement savings sector. This move underscores Mesirow's commitment to strengthening its position in the attractive retirement services market.

Ketan Shah, Chief Strategy Officer and General Counsel at Mesirow, highlighted the strategic importance of the acquisition, stating, "LeafHouse significantly enhances our fiduciary solutions platform by expanding our distribution reach while reinforcing our long-standing commitment to fiduciary excellence." He further emphasized that the transaction aligns with Mesirow's broader objective of investing in businesses that foster long-term, sustainable growth.

Todd Kading, President and CEO of LeafHouse, expressed optimism about the future, noting, "This next chapter allows us to build on what we do best — serving advisors with thoughtful technology and practical solutions." He anticipates accelerated innovation and expanded impact, enabling advisors and institutions to operate more efficiently and make better-informed decisions.

The retirement plan services sector is experiencing significant evolution, driven by increasing regulatory scrutiny and a growing demand for sophisticated, technology-enabled solutions. Firms like Mesirow are actively consolidating and enhancing their offerings to meet these demands, with assets in U.S. retirement plans exceeding trillions of dollars. This acquisition positions Mesirow to capture a larger share of this dynamic market by offering a more robust and integrated suite of fiduciary and advisory services.
