CINCINNATI and BOSTON, September 10, 2025 – Gateway Investment Advisers (“Gateway”), a pioneer in options-based investment strategies and affiliate of Natixis Investment Managers (“Natixis IM”), today announced the successful closing of its previously announced acquisition of the business of Belmont Capital Group (“Belmont”), a Los Angeles-based provider of customized, options-based separately managed account (SMA) strategies.
With the completion of the acquisition on August 29, 2025, Gateway is poised to further participate in the rapidly growing SMA market. The integration of Belmont’s expertise in single-stock risk management enhances Gateway’s ability to deliver tailored hedging and options strategies to clients and extends the capabilities of AIA, Natixis IM’s direct-indexing platform, by adding options-based overlay strategies to its tax management toolkit, including for high-net-worth individuals with concentrated equity positions.
Belmont’s investment team has joined Gateway and will continue to operate from Los Angeles, where Gateway has established a new office. Belmont’s strategies will shortly be rebranded under the Gateway name, with the original team continuing to manage them.
