Boston, Massachusetts, États-Unis, November 15, 2018
  • McDonnell Investment Management will be integrated into Loomis Sayles in early 2019
  • Both firms are affiliates of Natixis Investment Managers
  • The combined business will provide McDonnell’s clients with access to Loomis Sayles’ expansive investing, research and operational capabilities
  • Agreement will provide Loomis Sayles with extensive municipal bond investment capabilities

McDonnell Investment Management, LLC will be combined with Loomis, Sayles & Company, L.P. in early 2019, both firms announced today. Both companies are affiliates of Natixis Investment Managers. Based outside Chicago, McDonnell specializes in municipal and taxable bond strategies and manages $11.7 billion1 in assets. This combination will provide McDonnell clients with an enhanced offering backed by Loomis Sayles’ expansive investing, research and operational capabilities.

“Loomis Sayles is excited about this combination. We believe we can bring significant operational support to the McDonnell municipal investing effort, and free up the portfolio management team to focus on generating alpha,” said Kevin Charleston, chief executive officer of Loomis Sayles. “We also believe municipal investing is important to our clients, and we are pleased to expand our capabilities in that area.”

“First and foremost, we believe this is in the best interest of both McDonnell and Loomis Sayles clients,” said Mark Giura, chief executive officer and chief investment officer of McDonnell Investment Management. “This integration provides McDonnell clients access to investments backed by Loomis Sayles’ extensive research and technology resources, and supplies Loomis Sayles with key strategic municipal capabilities and additional expertise to serve the insurance market.”

“We fully support the decision by Loomis Sayles and McDonnell Investment Management to join forces,” said Jean Raby, CEO of Natixis Investment Managers. “The combination of this pair of our investment affiliates further enhances our fixed income offering and unlocks natural synergies that will benefit the clients of both firms.”

Natixis Investment Managers plans to transfer ownership of McDonnell Investment Management to Loomis Sayles on January 1, 2019. The McDonnell municipal portfolio management team will remain intact and will continue to operate out of the Oakbrook Terrace, Illinois, office. The management of McDonnell’s core/taxable fixed income strategies will be transitioned later in 2019 to the Loomis Sayles Relative Return team. To ensure continuity for McDonnell clients, Mark Giura will continue to lead the office and support existing client relationships, while managing the integration process with Loomis Sayles.

Loomis Sayles manages $267.3¹ billion in assets and looks far and wide for value – across traditional asset classes and alternative investments – to pursue attractive, sustainable returns for clients worldwide. McDonnell Investment Management manages municipal and core bond strategies for a well-diversified client base, including insurance companies and high net worth individuals.
