BCBSM Sells AF Group to Enstar in Strategic Healthcare Refocus

DETROIT, MI – February 13, 2026 – In a significant strategic realignment, Blue Cross Blue Shield of Michigan (BCBSM) has announced a definitive agreement to sell its wholly owned subsidiary, AF Group, to the global insurance and reinsurance giant Enstar Group. The acquisition, backed by the formidable investment firm Sixth Street, marks a pivotal moment for all three entities, signaling a deeper trend of portfolio optimization across the insurance sector.

This transaction allows BCBSM to divest a highly successful but non-core asset, redirecting substantial capital toward its primary mission of providing affordable healthcare. For AF Group, a national leader in specialty insurance, the sale promises a new era of growth under a parent company deeply embedded in the global insurance market. The deal, whose financial terms remain private, is expected to close in the fourth quarter of 2026, pending regulatory approvals.

A Strategic Pivot to Core Healthcare Mission

For BCBSM, the sale represents a deliberate and calculated move to fortify its financial foundation against the mounting pressures of the U.S. healthcare system. The nonprofit mutual insurance company plans to leverage the proceeds to double down on its commitment to its more than 4.7 million members.

"AF Group has grown and expanded to a point where it needs to be aligned with a parent organization that has the potential to take it to even greater heights of success," said Tricia Keith, president and CEO of Blue Cross Blue Shield of Michigan. Keith emphasized the core driver behind the decision: "As upstream health care costs continue to rise and put pressure on health insurance affordability, this agreement strengthens the financial foundation that allows us to continue fulfilling that mission."

AF Group's journey under BCBSM's ownership has been one of remarkable growth. Acquired in 1994 as a state-owned, single-state workers' compensation provider, it has been transformed into a national powerhouse in the property and casualty industry. In 2025 alone, AF Group reported consolidated gross written premiums of $3.3 billion, a testament to its market strength and a clear indicator of the significant capital this sale will unlock for BCBSM. This financial infusion is expected to be deployed into initiatives aimed at cost reduction, innovative care models, and enhancing capital reserves to ensure long-term stability for its health plan members.

A New Horizon for AF Group

Under the new ownership structure, AF Group is set to become a wholly owned subsidiary of Enstar, a Bermuda-based group with over $22 billion in assets. The deal is not seen as an absorption but as a strategic partnership designed to accelerate AF Group's trajectory. Both companies have stressed that AF Group will continue to operate largely as a standalone entity, maintaining its headquarters in Lansing, Michigan, and its current leadership team, including President and CEO Lisa Corless.

"We are grateful to Blue Cross Blue Shield of Michigan for a successful 32-year journey together and look forward to our continued success and future opportunities under Enstar's ownership," Corless stated. She highlighted the synergy between the companies, noting the transition "recognizes the strength of AF Group, combining our specialist expertise, underwriting discipline and people-first culture with Enstar's market experience and financial strength."

The backing of Sixth Street, a global investment firm with over $125 billion in assets under management, adds another powerful dimension to the acquisition. Sixth Street has a significant and growing footprint in the insurance sector, having led a $5.1 billion acquisition of Enstar itself in 2024. This context suggests a long-term strategic vision to build a dominant force in the insurance and reinsurance market. For AF Group, this means access to not only Enstar's global network and expertise in retrospective insurance solutions but also the vast capital and strategic resources of Sixth Street, positioning it for enhanced growth and market expansion.

Reshaping the Insurance M&A Landscape

This transaction is a prime example of the evolving dynamics in the insurance M&A landscape. It showcases a broader industry trend where large, diversified entities are shedding non-core assets to sharpen their focus, while specialist firms and private capital seek to acquire and scale up high-performing businesses.

Enstar, traditionally a leader in managing legacy insurance liabilities (retrospective solutions), gains a robust and active underwriting business in AF Group. This move represents a significant expansion of its capabilities into the "live market," allowing it to offer a broader suite of prospective insurance solutions. Enstar's leadership has called the acquisition a "compelling live market opportunity" that complements its existing strengths and broadens its client-serving capabilities.

The deal's closure is contingent on navigating a complex regulatory environment. Approvals will be required from the Michigan Department of Insurance and Financial Services (DIFS) as well as numerous other state insurance departments where AF Group operates. The projected closing date in late 2026 reflects the thorough review process required for a transaction of this scale, ensuring financial stability and protection for policyholders are maintained. As the industry watches this major consolidation play out, competitors will likely be spurred to re-evaluate their own strategic positions in an increasingly competitive and specialized market.
