Mariner Expands Institutional Consulting Services with $292 Billion Acquisition

In a significant move that reshapes the landscape of institutional financial consulting, Mariner has announced the acquisition of Cardinal Investment Advisors, adding $292 billion in assets under advisement and approximately 40 employees to its Mariner Institutional practice. This strategic acquisition, finalized on January 3, 2025, marks a pivotal moment in Mariner's ambitious 2025 national expansion plan, propelling the firm's total assets under advisement to an impressive $550 billion in the first quarter of 2025.

The merger between Mariner and Cardinal Investment Advisors represents more than just a financial transaction; it signifies a transformative shift in the institutional consulting services sector. By combining Cardinal's specialized expertise, particularly in insurance advisory services, with Mariner's extensive resources, the newly expanded entity is poised to address the increasingly complex challenges faced by institutional investors in today's dynamic financial landscape.

Marty Bicknell, CEO and president of Mariner, emphasized the strategic importance of this acquisition, stating that it kickstarts a year focused on growth, innovation, and enhanced client-focused financial services. The move is designed to establish Mariner as the premier partner for institutional consulting services, setting a new industry standard for tailored, innovative solutions.

Cardinal Investment Advisors, with offices in Chicago and St. Louis, brings to the table a rich history of delivering customized investment consulting services since 2001. Their client base, which includes insurance companies, corporate retirement plans, healthcare systems, foundations, and endowments, will now benefit from the expanded capabilities and resources of the combined entity. This integration is particularly significant for the insurance sector, as Cardinal's expertise will form the foundation of Mariner Institutional's insurance advisory practice.

The acquisition addresses the growing demand for sophisticated institutional consulting services, driven by increasing market complexities and the need for highly customized investment solutions. As institutional investors face ever-more challenging financial environments, the combined expertise of Mariner and Cardinal is expected to provide a competitive edge in developing strategies that align with each organization's unique liability profile and investment goals.

Mike Welker, National Managing Director leading Mariner Institutional, highlighted the partnership's focus on shaping the future of institutional consulting while maintaining a client-first approach. The integration of Cardinal's experienced team and capabilities is expected to enhance Mariner's service offerings and solidify its position as a trusted advisor to institutions navigating complex financial landscapes.

The merger also brings together two cultures committed to excellence and employee satisfaction. Cardinal's recognition as one of the best places to work in money management for ten consecutive years aligns with Mariner's emphasis on fostering a positive and productive workplace culture. This cultural synergy is likely to facilitate a smooth integration and drive innovation in client services.

As the financial services industry continues to evolve, this acquisition positions Mariner at the forefront of institutional consulting. The firm's expanded capabilities, coupled with its commitment to customized solutions and client-focused approach, are set to redefine the standards of institutional financial advisory services. For institutional investors, this merger promises access to a broader range of expertise and resources, potentially leading to more sophisticated and effective investment strategies tailored to their specific needs.

The completion of the Mariner and Cardinal integration by the end of March 2025 will mark the beginning of a new era in institutional consulting. Under Mariner's "One Mariner" strategy, the combined entity will offer a comprehensive suite of services, empowering advisors to create highly customized solutions that address the multifaceted needs of institutional clients. This holistic approach, backed by enhanced resources and expertise, positions Mariner to navigate the complexities of the modern financial landscape effectively, potentially setting new benchmarks for the entire industry.
