The value of revenues earned worldwide by MGA, MGU and cover-holder groups (a.k.a. delegated underwriting authority / underwriting agency groups) was around USD 17.3 billion, signifying annual growth in this sector of around 19% before adjusting for inflation.
According to an updated ranking and analysis completed by Insuramore, this is substantially ahead of the growth rate of world’s insurance broking sector which, as reported by Insuramore in a related press release on 6th June 2023, is believed to have advanced in value by almost 10.5% in 2022.
Rankings of the world’s leading MGA / MGU / cover-holder groups by total revenues derived globally from delegated underwriting activity across all types of insurance (and reinsurance)
As a group, Brown & Brown was ranked first globally in this arena in 2022 having become the first group to generate more than USD 1 billion in annual revenues from this activity.
It has since built on that position during 2023 through the announcement of its intended acquisition of Kentro Capital, parent company of Nexus Underwriting.
In descending order, Brown & Brown is likely to have been followed from second to fifth by Truist Insurance Holdings, Amwins, Ryan Specialty Group and Gallagher, with these top five groups holding a combined market share of just under 20% of global MGA revenues.

| 1 | Brown & Brown | 6,18% |

By ownership, 54 of the top 300 groups in this space in 2022 are classifiable as broker-owned, 28 as insurer-owned and the remaining 218 as independent (albeit many of these are backed by private equity firms).
Among insurer-owned groups, Insuramore judges that Munich Re generated the highest revenues from proprietary MGA business in 2022 while NSM Insurance Group was the largest independent group.
MGA Groups Worldwide by Type
Furthermore, by location of headquarters, with 170 in total and benefiting from the strength of the US dollar against most other global currencies, the US played host to the most MGA groups in the top 300 in 2022 with the UK (49), the Netherlands (13), Canada (12) and Germany (10) coming next on this count.
As would be expected given the very high industry-wide growth rate, almost all MGA groups experienced an increase in their revenues and 11 of the top 300 are believed likely by Insuramore to have more than doubled their income relative to last two years.
The most rapid year-on-year growth is likely to have been achieved by Acrisure following its acquisition of both Appalachian Underwriters and Volante Global during 2022. Cyber insurance specialists such as Coalition, Envelop and Resilience also feature among the groups that more than doubled their revenues in 2022.
MGA Groups Worldwide by Region
What is Insurance MGA?
A managing general agent (MGA) is a specialized type of insurance agent/broker that, unlike traditional agents/brokers, is vested with underwriting authority from an insurer.
Worldwide, there are over 2,500 individual enterprises involved in MGA activity among which around a half are likely to have written premiums of more than USD 10 million in, and regular new launches appear to be sustaining this volume.
Nevertheless, other significant acquisitions in this space that were in the process of being completed during the first half of 2023 included those of Envest by Ardonagh Group, BridgeForce by HUB, both Taga and Tay River Holdings by Gallagher, Acquis Insurance Management by NSM Insurance Group, Animal Friends by Pinnacle Pet Group, and Griffin Underwriting Services by Ryan Specialty Group.
In addition, Amynta Group has concluded its acquisition of Ambridge from Fairfax Financial.
Accordingly, MGAs perform certain functions ordinarily handled only by insurers, such as binding coverage, underwriting and pricing, appointing retail agents within a particular area, and settling claims.
Typically, MGAs are involved with unusual lines of coverage, such as professional liability and surplus lines of insurance, in which specialized expertise is required to underwrite the policies.
However, MGAs also write some personal lines business, especially in geographically isolated areas (e.g., western Oklahoma, North Dakota) where insurers do not want to set up a branch office. MGAs benefit insurers because the expertise they possess is not always available within the insurer’s home or regional offices and would be more expensive to develop on an in-house basis.
MGA, MGU and cover-holder revenues are defined as fees and commissions earned fromunderwriting / program administration (and related activities, such as claims management) byentities with the authority to underwrite or bind insurance (or reinsurance) risk in any class andthat do this exclusively or mainly on behalf of unaffiliated carrier partners. Such entities that areinsurer-owned and that are believed to place risks exclusively or mainly with parent or sisterunderwriters (i.e. affiliated entities) are excluded from the analysis. Revenues from wholesale orother broking / agency activity that do not meet this definition of MGA, MGU or cover-holderbusiness are also not in scope.
