Northwestern Mutual, Sixth Street Form $13B Partnership 

Northwestern Mutual announced a strategic partnership with Sixth Street to support its investment strategy for its institutional investment portfolios that will involve $13 billion in assets managed by Sixth Street, with potential for future growth.  

Northwestern Mutual will acquire a minority stake in the $100 billion global investment firm for an undisclosed amount, and Sixth Street will manage investments across multiple strategies, including asset-based finance and opportunistic investments in real estate and infrastructure debt and equity, under the agreement. 

Northwestern Mutual’s institutional investment portfolios currently total more than $320 billion in assets. Northwestern Mutual Capital, the private equity division of Northwestern Mutual, recently closed its Northwestern Mutual Capital Equity Fund VII and parallel fund at $473 million, exceeding its $400 million target. 

The Sixth Street partnership coincides with significant growth for Northwestern Mutual, headquartered in Milwaukee, which oversees more than $627 billion in total assets and provides $2.3 trillion in life insurance coverage. The firm has recently disclosed intentions for an unprecedented $8.2 billion dividend distribution to policyholders in 2025. 

The transaction was advised by Morgan Stanley and Debevoise & Plimpton for Northwestern Mutual, while Sixth Street received guidance from Evercore, Simpson Thacher & Bartlett, and Cleary Gottlieb Steen & Hamilton.
