NSM Insurance Group Completes Transaction with New Mountain Capital

In a significant move within the insurance sector, NSM Insurance Group, a prominent global specialty insurance provider, has finalized the sale of its U.S. commercial insurance division to New Mountain Capital, a highly regarded investment firm based in New York. This transaction marks a pivotal moment for NSM as it embarks on a new chapter aimed at stimulating growth and innovation across its insurance platforms.

The announcement was made on April 15, 2025, revealing that New Mountain Capital, which manages over $55 billion in assets, will now oversee NSM's extensive portfolio that includes 15 leading niche insurance programs across various sectors such as Property & Casualty, Accident & Health, and Reinsurance. In addition, the transaction encompasses NSM’s retail agency, NSM Insurance Brokers, positioning New Mountain to leverage NSM's established market presence to further enhance performance.

Key Developments Post-Transaction

As a result of this strategic agreement, NSM will evolve into two independent entities. Both entities will introduce new brands that reflect their distinct operational focuses and market strategies. Details regarding the forthcoming brands associated with the U.S. commercial division and the remaining consumer-focused insurance brands are expected to be announced shortly. This separation is seen as an essential step in positioning NSM for dynamic growth and specialization, allowing each entity to cater precisely to its target market.

Furthermore, the leadership of the newly formed entity backed by New Mountain Capital has seen changes, with Geof McKernan, the founder of NSM, and Bill McKernan joining its board of directors. Aaron Miller, formerly the Chief Commercial Lines Officer at NSM, steps in as the new Chief Executive Officer, taking immediate command of the operations.

Geof McKernan expressed his satisfaction with the transaction, stating, "We are extremely pleased to complete the transaction with New Mountain, and I'm confident they are the perfect partner to accelerate the growth of the business. We aim to deliver significant value to our team, partners, and customers as we move forward."

New Mountain's Managing Director, Robert Mulcare, and Director, Sean Donovan, conveyed enthusiasm about this milestone. They expressed eagerness to work closely with the NSM team, particularly Aaron, in building the independent commercial insurance MGA into a recognized leader within the industry, known for its exceptional talent, innovative solutions, and specialized offerings.
