Four Decades of Delivering Value and Trust
Founded in Boston in 1980, we manage $11.1 billion in six U.S. equity strategies. We use internal proprietary fundamental research on small-cap, smid-cap and mid-cap companies to build client portfolios.
We offer growth, value and core styles, enabling us to tailor strategies to our clients’ goals while maintaining a disciplined and consistent process. This flexibility, combined with our deep expertise, allows us to identify opportunities across this market segment.
Frontier’s ownership structure consists of broad employee participation—including 18 of its 39 employees—and a partnership with Affiliated Managers Group, Inc. (“AMG”). AMG, a global asset management company with equity interests in leading boutique investment firms, purchased a majority stake in Frontier in 2000. This arrangement preserves Frontier’s operational, cultural, and investment autonomy, ensuring that equity incentives remain in place for employees to continue building an enduring franchise that will serve clients for generations.

We believe that a disciplined and consistent approach to proprietary fundamental analysis—focusing on individual company performance and financial health—leads to superior long-term investment performance.
Our Approach
Our meticulous research process is the foundation of our success. Each year, our team evaluates the universe of small- and mid-cap stocks, identifying opportunities that we believe have the greatest potential for long-term growth.
We continually challenge our investment theses, rigorously evaluate company management teams and assess the performance of portfolio holdings. Every buy and sell decision is informed by thorough examination and a deep understanding of market dynamics.
We invest in stocks with prospects for improving businesses with long-term unrecognized earnings power that are selling at attractive valuations. We have adhered to this approach since the firm’s inception.

A Variety of Styles to Meet Client Needs
Expertise, discipline, and focus are the cornerstones of our approach to managing client assets. With a performance record spanning over 40 years, we have built a legacy of delivering results through a consistent investment process.
Our strategies are designed to align with our clients’ goals, encompassing value, core, and growth investment styles. While our methodology remains consistent across all approaches, we integrate style-specific enhancements seeking to maximize performance and generate returns that exceed market benchmarks.
This long-standing expertise, disciplined process and focus enable us to navigate market complexities and provide solutions tailored to meet the unique preferences of our clients.
