Mike will co-manage the $45.2 billion* Core Plus Fixed Income strategy alongside Rick Raczkowski, Co-Head of the Relative Return Team and co-founder of the strategy. In this role, Mike succeeds Peter Palfrey, who retired as of 30 September 2026 after a distinguished 42-year investment career, including 25 years at Loomis Sayles.

As Co-Portfolio Manager of Core Plus Fixed Income, Mike will help oversee one of Loomis Sayles’ flagship fixed income strategies which invests in “plus” sectors including high yield, non-US dollar, collateralized loan obligations (CLOs), bank loans, and Treasury inflation-protected securities (TIPS) for additional yield potential and diversification. Mike was named Associate Portfolio Manager for the strategy in 2023.

Following Peter Palfrey’s retirement, Mike has also been named sole Portfolio Manager of the Loomis Sayles Active US Treasury strategy, for which he had previously served as Co-Portfolio Manager alongside Peter since 2020.

“Mike has consistently demonstrated strong investment expertise, sound judgment and a deep understanding of the Core Plus investment process,” said Rick Raczkowski, Co-Head of the Relative Return Team and Portfolio Manager. “Over the past several years, he has worked closely with Peter and me on portfolio positioning, structure and sector allocation across the strategy. I am confident he is exceptionally well prepared to assume this leadership role and help guide the strategy into the future.”

“Loomis Sayles has a long-standing commitment to developing investment talent through thoughtful succession planning,” said David Waldman, Chief Investment Officer of Loomis Sayles. “Mike’s promotion reflects his individual accomplishments as well as the strength and depth of the Relative Return Team.”

Mike joined Loomis Sayles in 2004 as a Global Settlements Administrator before moving to the trading desk in 2006. He was promoted to Director of US Rates Trading in 2020 and joined the Relative Return Team in 2021 as a Senior Strategist responsible for macro positioning, portfolio structure and sector allocation. He has served as co-leader of the firm’s US Yield Curve Sector Team since 2014. Prior to joining Loomis Sayles, Mike was a bank specialist for the international trade support team at Putnam Investments. He earned a BA from the University of Vermont and an MBA from Boston University.
