Agrees to acquire At-Bay for $575 million
The transaction would place the cyber MGA and security platform under Hartford Steam Boiler. Closing is expected in the first quarter of 2027, subject to approvals.
Munich, Germany · Global
A global reinsurance group whose operations span property-casualty and life reinsurance, primary insurance through ERGO and Global Specialty Insurance. Its HSB business supplies technology-focused specialty capacity and would oversee At-Bay if the announced cyber-platform acquisition closes.
Munich Re's importance to MGAs extends beyond the size of its balance sheet. The group participates through reinsurance, specialty primary insurance and strategic ownership, which are different ways of supporting or competing for business. A prospective partner needs to identify the actual operating entity and contract involved. Group-level financial strength does not, by itself, establish a particular program's appetite, delegated authority or renewal terms.
The announced At-Bay transaction illustrates the move toward owning capabilities that operate throughout a policy's life. Munich Re's August 2026 announcement described an agreement, with completion expected in early 2027 subject to conditions, rather than a completed acquisition. It also identified HSB as a strategic partner since At-Bay's founding. The proposed combination therefore builds on an existing relationship; it should not be presented as the first connection between the two businesses.
Our assessment is that the difficult part of an insurance-and-security proposition is proving the link between intervention and insured outcomes. A vulnerability detected is not the same as a vulnerability remediated, and a remediation is not automatically evidence of an avoided claim. Useful evaluation would compare incident frequency and severity across reasonably comparable customer groups, account for differences in risk selection and track how findings change pricing or coverage decisions. Those are tests for the strategic thesis, not claims that the proposed combination has already delivered them.
Segment reporting provides another important distinction. Munich Re reports Global Specialty Insurance separately within its reinsurance field of business, although the segment groups specialty primary-insurance activities. In its 2025 results, the company attributed the segment's improved combined ratio to lower major-loss expenditure. Readers should therefore avoid interpreting every improvement as proof of better underlying risk selection, or treating the segment's results as a standalone measure of MGA-originated business. A change in reporting visibility is useful, but it does not eliminate the need to understand portfolio mix and loss experience.
For MGA leaders, the broader implication is that distribution access may be only one component of strategic value. A business that can document risk information, influence loss prevention and support credible claims feedback may offer capabilities a carrier cannot readily reproduce through an ordinary distribution agreement. The counterweight is execution: ownership can add resources while also introducing new approval processes and integration demands. In our view, the best evidence would show which decisions become better, which customer outcomes improve and whether those gains persist without weakening independent underwriting discipline. An announced acquisition price cannot answer those questions.

Munich Re said the acquisition is intended to combine insurance, proactive mitigation and technology as the market moves beyond standalone coverage.
The newly separated segment produced €8.625 billion of 2025 insurance revenue and an 85.9% combined ratio, all company reported.
Munich Re began reporting the segment separately to reflect its growing strategic importance within the reinsurance field of business.
The U.S. digital insurer was fully included in 2025 results, expanding Munich Re’s direct position in small-business insurance alongside its reinsurance and delegated-market relationships.
