CAPITAL PARTNERS Fee Income We pursue a number of other opportunities, including creating and managing our joint ventures and managed funds, executing structured reinsurance transactions to assume or cede risk and managing certain strategic investments. These opportunities aid us in generating our second driver of profit, the fee income that we earn on our capital management business. We earn two types of fee income by managing third-party capital in our Capital Partners unit: management fee income and performance fee income. Compared to underwriting income, we view fee income, especially management fee income, as being a relatively less volatile and diversifying source of income. Our capital management business is one of the oldest, largest and most respected in the industry and provides us with a larger capital base, through which we are able to write more business and reach a 8
At the same time, this business benefits our customers, as it allows us to write more risk in various forms across balance sheets with diversified counterparties. We are also able to offer additional investment opportunities to institutional and other investors to serve as our capital partners and make targeted investments in certain of the products that we offer. Managed Joint Ventures and Managed Funds We manage a number of joint ventures and managed funds which provide us with an additional presence in the market, enhance our client relationships and generate management fee income and performance fee income. Currently, our principal joint ventures and managed funds include DaVinci, Fontana, Medici, Vermeer, Top Layer and Upsilon. December 31, 2024 Entity Consolidated (1)

Behind the comparison

Sources and methodology

Price return uses split-adjusted daily closes and excludes dividends. Both stocks start on the first shared trading day within the selected window. Unavailable metrics leave gaps.

Financials use SEC canonical statements available by the displayed cutoff, retaining each company's fiscal period end. Annual and quarterly amounts are shown separately. P/E is unavailable when earnings do not support a positive ratio.

Business overlap uses industry tags from annual filings released in 2025. Each core activity receives full weight; each material activity receives one quarter of that weight. Rarer industries carry more weight. We sum the smaller exposure for each shared activity and divide it by the sum of the larger exposure for every activity in either company. This measures business overlap, rather than price correlation or expected returns.

Search eligibility requires distinct issuers, a shared core category and at least 20% weighted overlap, supported by industry or sector evidence and specific business activities. Broad classifications require stronger overlap within the same sector. Comparisons also need at least 252 shared price observations within two years, recent trading and a common sourced revenue or net-income trend. Missing P/E or gross margin alone does not exclude a comparison. The eligibility snapshot refreshes daily. Related comparisons use a separate, stricter peer rule; their ten-peer discovery limit does not limit search eligibility. Other stock pairs remain available in the comparison tool.
