Insurance M&A Values Surge Despite Fewer Deals in 2024

Insurance industry merger and acquisition activity is poised for significant growth in 2025, with nine out of 10 insurers expecting to close more deals than in 2024, a year that saw fewer transactions but higher aggregate deal values across all sectors, according to analysis by Deloitte.
The U.S. and Bermuda insurance industry experienced a slight decrease in M&A activity during 2024, with deal count declining across all sectors. Despite fewer transactions (519 vs. 537), aggregate deal values increased 72% to $49.4 billion, driven by several transformative deals.
2024 Deal Activity Overview
The Life and Annuity (L&A) sector saw the most dramatic shift, with transactions dropping 35% from 17 deals in 2023 to just 11 in 2024, the report noted. However, aggregate deal value surged 92% to $11.1 billion from $5.8 billion the previous year. This substantial increase was largely influenced by Nippon’s $8.2 billion acquisition of the remaining shares in Resolution Life’s investment limited partnership, which valued Resolution Life at $10.6 billion.
Excluding this major transaction, the L&A sector’s aggregate deal value was approximately $2.9 billion, still slightly above 2023’s normalized value of $2.2 billion.
Property and Casualty (P&C) deals declined 9% to 32 transactions, down from 35 in 2023. Despite fewer deals, aggregate value increased 54% to $6.7 billion from $4.3 billion. This growth was heavily influenced by Bermuda-based Enstar Group’s transaction with Sixth Street, J.C. Flowers, and Liberty Strategic Capital, estimated at $5.1 billion. When excluding this deal, the P&C sector’s aggregate value was about $2.1 billion, representing a 50% increase from 2023’s normalized value.
The insurance brokerage sector maintained its position as the most active area for insurance M&A, with 476 deals in 2024, nearly matching 2023’s 485 transactions, according to Deloitte. Average deal value in this sector increased dramatically by 207% to $2.1 billion, up from $700 million in 2023. This spike was primarily due to two major Truist Insurance Holdings transactions: its acquisition by Stone Point Capital and other investors for $7.6 billion, and Marsh & McLennan’s purchase of McGriff Insurance Services for $7.8 billion.
Key Market Dynamics
Several notable trends characterized the insurance M&A landscape in 2024, the Deloitte report noted. Private equity participation dominated the market between 2017 and 2022 with approximately 70% of transactions. PE share of the deals fell to 50% in 2023 and 2024. This decline coincided with the rising interest rate environment, affecting investment strategies and valuations.
Deal completion timelines extended beyond expectations for many transactions, creating uncertainty in the market. Additionally, some widely anticipated mergers proved smaller in scope than initially projected, tempering market expectations.
Market Context
The broader economic environment provided a mixed backdrop for insurance industry M&A activity, according to the report. A rising stock market created favorable conditions for equity-based transactions, while declining inflation helped stabilize economic outlooks and financial projections.
In Washington, the political landscape shifted with a new administration preparing to work with Republican majorities in both the House and Senate for at least the next two years. This political realignment, combined with numerous provisions of the Tax Cuts and Jobs Act (TCJA) set to expire at the end of 2025, created both uncertainty and potential opportunity for strategic dealmaking, according to Deloitte’s analysis.
In 2025, Deloitte said that insurance M&A trends point to increased deal activity with 90% of insurance companies anticipating more closures and restructuring. Climate risk concerns continue driving sustainability-focused acquisitions despite shifting corporate priorities, particularly in L&A and P&C sectors targeting foreign entities.
With the TCJA provisions expiring this year, transaction timing becomes critical as carriers may need to act quickly on opportunities, the report noted. Meanwhile, available capital from reserves and underwriting earnings could make insurtech companies attractive acquisition targets for innovation and modernization in a rapidly evolving global tax environment, according to the report.
