Japan’s Monex Group has acquired a 20% stake in Boston-based Westfield Capital Management, a step the company said will deepen its presence in the US asset management space.
The investment aligns with Monex’s long-term strategy to diversify geographically and strengthen its presence in one of the world’s most dynamic equity markets.
A Strategic Step into the U.S. Market
With this acquisition , valued at $103 million, Westfield Capital becomes an equity-method affiliate, reportedly bringing with it over $24 billion in assets under management and a focus on equity investing.
“This transaction represents a significant step in our ongoing efforts to invest in growth areas,” commented Yuko Seimei, the CEO of Monex Group.
“We believe Westfield’s consistent performance in the U.S. equity markets, paired with its disciplined investment process, complements our existing capabilities and opens new doors for potentially cross-selling high-quality strategies to our Japanese client base,” he added.
Founded in 1989, Westfield’s revenue topped $100 million in 2024. The company has more than 60 staff members with over two decades of experience on average.
Westfield Looks East
For Westfield, the deal presents an opportunity to expand its reach into Asia. CEO William A. Muggia noted that the firm, having scaled organically in the US over the past two decades, now sees strong potential in the Japanese market.
“Looking ahead to the next 20 years, we are energized to leverage our platform for expansion in Asia alongside our new partner, Monex Group. Over the past 20 years, we’ve had great success scaling our business organically in the US, and we believe there is a tremendous opportunity to introduce our strategies to the Japanese marketplace,” Muggia said.
The transaction, executed through Monex’s special purpose entity in the US, involves the use of some external debt, which the company said will help enhance capital efficiency and support a higher return on equity (ROE) in the medium to long term.
Westfield’s leadership and investment approach will reportedly remain unchanged following the deal, ensuring continuity for existing clients and employees.
Meanwhile, Monex looks to tap into its domestic partner ecosystem, particularly through its alliance with NTT DOCOMO, to distribute Westfield’s strategies more broadly in Japan.
