Liberty Mutual Investments partners with Square Nine Capital

Liberty Mutual Investments, the investment firm for Liberty Mutual, and Square Nine Capital announced a long-term strategic partnership, focused on supporting the growth of Square Nine as it pursues solutions-oriented corporate credit investments. Through the partnership, the firms expect to collaborate on investment opportunities sourced across Square Nine’s platform.

Founded in 2025 by investment industry veterans Peter Ma and Nicole Musicco, Square Nine focuses on senior secured loans and structured capital solutions for U.S. middle-market companies in complex situations, typically outside of a traditional LBO framework, including opportunities created by periods of market dislocation. The firm draws on a broad origination network designed to support selective, disciplined underwriting.

LMI invests more than $124 billion of long-term capital globally across its integrated platform on behalf of Liberty.

“This is a segment of the market that has long been underserved by traditional capital despite its resilience across market cycles. Square Nine brings an active, partnership-oriented approach to private credit that aligns closely with LMI’s long-term investing strategy. We are thrilled to partner with Peter and Nicole as they scale Square Nine and pursue attractive opportunities in this overlooked segment.” – John Reichard, Head of Partnerships within Global Credit Markets at Liberty Mutual Investments.

“We are excited to partner with Liberty Mutual Investments at this formative stage for Square Nine. LMI’s long-term approach, strategic perspective and alignment with our values make them an ideal partner as we work to build a differentiated corporate credit platform focused on bespoke opportunities in the U.S. middle market.” – Peter Ma and Nicole Musicco, Co-Managing Partners of Square Nine.
