Non-GAAP Financial Measures Reconciliation

We present our results of operations in a way that we believe will be the most meaningful and useful to investors, analysts, rating agencies and others who use our financial information to evaluate our performance. Some of the measurements are considered non-GAAP financial measures under SEC rules and regulations. In this press release, we present underwriting income (loss), a non-GAAP financial measure as defined in Item 10(e) of SEC Regulation S-K. We believe that non-GAAP financial measures, which may be defined and calculated differently by other companies, help explain and enhance the understanding of our results of operations. However, these measures should not be viewed as a substitute for those determined in accordance with U.S. GAAP. Where appropriate, reconciliations of our non-GAAP measures to the most comparable GAAP figures are included below.

Underwriting Income (Loss)

We calculate underwriting income (loss) on a pre-tax basis as net premiums earned less losses and loss adjustment expenses, acquisition costs and other underwriting expenses (net of third party fee income). We believe that this measure of our performance focuses on the core fundamental performance of the Company’s reportable segments in any given period and is not distorted by investment market conditions, corporate expense allocations or income tax effects.

The following table reconciles underwriting income (loss) to net income (loss), the most comparable GAAP financial measure:

	Three Months Ended				Six Months Ended
	June 30,				June 30,
($ in thousands)	2024		2023		2024		2023
Underwriting income (loss)	$	65,299	$	34,894	$	97,825	$	68,956
Total net realized and unrealized gains (losses) on investments and net investment income (loss)	164,971		26,697		432,960		64,189
Other income (loss), excluding third party fee income	—		(29)		—		—
Net foreign exchange gains (losses)	(1,782)		(3,341)		(3,911)		(5,387)

Net income (loss), prior to non-controlling interest	$	200,382	$	41,288	$	477,714	$	94,290

Third Party Fee Income

Third party fee income includes income that is incremental and/or directly attributable to our underwriting operations. It is primarily comprised of fees earned by the International Segment for management services provided to third party syndicates and consortia and by the Bermuda Segment for performance based management fees generated by our third party capital manager, Ada Capital Management Limited. We believe that this measure is a relevant component of our underwriting income (loss).

The following table reconciles third party fee income to other income, the most comparable GAAP financial measure:

	Three Months Ended				Six Months Ended
	June 30,				June 30,
($ in thousands)	2024		2023		2024		2023
Third party fee income	$	5,989	$	2,449	$	13,470	$	5,452
Other income (loss), excluding third party fee income	—		(29)		—		—
Other income (loss)	$	5,989	$	2,420	$	13,470	$	5,452

Other Underwriting Expenses

Other underwriting expenses include those general and administrative expenses that are incremental and/or directly attributable to our underwriting operations. While this measure is presented in Note 8, Segment Reporting, in the unaudited condensed consolidated financial statements, it is considered a non-GAAP financial measure when presented elsewhere.

Corporate expenses include holding company costs necessary to support our reportable segments. As these costs are not incremental and/or directly attributable to our underwriting operations, these costs are excluded from other underwriting expenses, and therefore, underwriting income (loss). General and administrative expenses, the most comparable GAAP financial measure to other underwriting expenses, also includes corporate expenses.

The following table reconciles other underwriting expenses to general and administrative expenses, the most comparable GAAP financial measure:

	Three Months Ended				Six Months Ended
	June 30,				June 30,
($ in thousands)	2024		2023		2024		2023
Other underwriting expenses	$	48,655	$	42,743	$	92,008	$	81,886
Corporate expenses	16,262		6,491		27,764		13,154
General and administrative expenses	$	64,917	$	49,234	$	119,772	$	95,040

Our expectations, beliefs, and projections are expressed in good faith and we believe there is a reasonable basis for them. However, there can be no assurance that management’s expectations, beliefs and projections will be achieved and actual results may vary materially from what is expressed in or indicated by the forward-looking statements.

•we have significant foreign operations that expose us to certain additional risks, including foreign currency risks and political risk;

•we do not control the allocations to and/or the performance of the Two Sigma Hamilton Fund, LLC ("TS Hamilton Fund")’s investment portfolio, and its performance depends on the ability of its investment manager, Two Sigma Investments, LP ("Two Sigma"), to select and manage appropriate investments and we have a limited ability to withdraw our capital accounts;

•downgrades, potential downgrades or other negative actions by rating agencies;

13

•our potential need for additional capital in the future and the potential unavailability of such capital to us on favorable terms or at all;

•operational failures, failure of information systems or failure to protect the confidentiality of customer information, including by service providers, or losses due to defaults, errors or omissions by third parties or our affiliates;

•we are a holding company with no direct operations, and our insurance and reinsurance subsidiaries’ ability to pay dividends and other distributions to us is restricted by law;

•risks relating to our ability to identify and execute opportunities for growth or our ability to complete transactions as planned or realize the anticipated benefits of our acquisitions or other investments;

•our potentially becoming subject to U.S. federal income taxation, Bermuda taxation or other taxes as a result of a change of tax laws or otherwise;

•the potential characterization of us and/or any of our subsidiaries as a passive foreign investment company, or PFIC;

•our potentially becoming subject to U.S. withholding and information reporting requirements under the U.S. Foreign Account Tax Compliance Act, or FATCA, provisions;

•our costs will increase as a result of operating as a public company, and our management will be required to devote substantial time to complying with public company regulations;

•if we were to identify a material weakness and were unable to remediate such material weakness, or fail to achieve and maintain effective internal controls, our operating results and financial condition could be impacted and the market price of our Class B common shares may be negatively affected;

•the lack of a prior public market for our Class B common shares means our share price may be volatile and anti-takeover provisions contained in our organizational documents could delay management changes;

•the potential that the market price of our Class B common shares could decline due to future sales of shares by our existing shareholders;

•applicable insurance laws, which could make it difficult to effect a change of control of our company; and
