1 Basis of Presentation All financial information contained herein is unaudited, however, certain information relating to the consolidated balance sheet at the most recent year end is derived from or agrees to audited financial information. Unless otherwise noted, all data is in thousands, except for share and per share amounts and ratio information. This information is being provided for informational purposes only. It should be read in conjunction with the documents filed by Hamilton Insurance Group, Inc. ("Hamilton") with the U.S Securities and Exchange Commission, including its Form 10-Q. Special Note Regarding Forward-Looking Statements This information includes “forward looking statements” pursuant to the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by the use of terms such as “believes,” “expects,” “may,” “will,” “target,” “should,” “could,” “would,” “seeks,” “intends,” “plans,” “contemplates,” “estimates,” or “anticipates,” or similar expressions which concern our strategy, plans, projections or intentions. These forward-looking statements appear in a number of places throughout and relate to matters such as our industry, growth strategy, goals and expectations concerning our market position, future operations, margins, profitability, capital expenditures, liquidity and capital resources and other financial and operating information. By their nature, forward-looking statements: speak only as of the date they are made; are not statements of historical fact or guarantees of future performance; and are subject to risks, uncertainties, assumptions, or changes in circumstances that are difficult to predict or quantify. 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. There are a number of risks, uncertainties, and other important factors that could cause our actual results to differ materially from the forward-looking statements contained herein. Such risks, uncertainties, and other important factors include, among others, the risks, uncertainties and factors set forth in “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the “Form 10-K”) and other subsequent periodic reports filed with the Securities and Exchange Commission and the following: • our results of operations and financial condition could be adversely affected by unpredictable catastrophic events, global climate change or emerging claim and coverage issues; • our business could be materially adversely affected if we do not accurately assess our underwriting risk, our reserves are inadequate to cover our actual losses, our models or assessments and pricing of risks are incorrect or we lose important broker relationships; • the insurance and reinsurance business is historically cyclical and the pricing and terms for our products may decline, which would affect our profitability and ability to maintain or grow premiums; • 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; • Two Sigma Principals, LLC, Two Sigma and their respective affiliates have potential conflicts of interest that could adversely affect us; • the historical performance of Two Sigma is not necessarily indicative of the future results of the TS Hamilton Fund’s investment portfolio or of our future results;
2 Basis of Presentation (continued) Special Note Regarding Forward-Looking Statements (continued) • our ability to manage risks associated with macroeconomic conditions resulting from geopolitical and global economic events, including public health crises, current or anticipated military conflicts, terrorism, sanctions, rising energy prices, inflation and interest rates and other global events; • our ability to compete successfully with more established competitors and risks relating to consolidation in the reinsurance and insurance industries; • downgrades, potential downgrades or other negative actions by rating agencies; • our dependence on key executives, including the potential loss of Bermudian personnel as a result of Bermuda employment restrictions, and the inability to attract qualified personnel, particularly in very competitive hiring conditions; • our dependence on letter of credit facilities that may not be available on commercially acceptable terms; • our potential need for additional capital in the future and the potential unavailability of such capital to us on favorable terms or at all; • the suspension or revocation of our subsidiaries’ insurance licenses; • risks associated with our investment strategy, including such risks being greater than those faced by competitors; • changes in the regulatory environment and the potential for greater regulatory scrutiny of the Company going forward; • a cyclical downturn of the reinsurance industry; • 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 • investors may have difficulties in serving process or enforcing judgments against us in the United States. There may be other factors that could cause our actual results to differ materially from the forward-looking statements, including factors disclosed under the sections entitled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Form 10-K and other subsequent periodic reports filed with the Securities and Exchange Commission. You should evaluate all forward-looking statements made herein in the context of these risks and uncertainties.
3 Basis of Presentation (continued) Special Note Regarding Forward-Looking Statements (continued) You should read this information completely and with the understanding that actual future results may be materially different from expectations. We caution you that the risks, uncertainties, and other factors referenced above may not contain all of the risks, uncertainties and other factors that are important to you. In addition, we cannot assure you that we will realize the results, benefits, or developments that we expect or anticipate or, even if substantially realized, that they will result in the consequences or affect us or our business in the way expected. All forward-looking statements contained herein apply only as of the date hereof and are expressly qualified in their entirety by these cautionary statements. We undertake no obligation to publicly update or revise any forward-looking statements to reflect subsequent events or circumstances.

Our peak natural catastrophe PMLs are derived using vendor catastrophe models that serve as a baseline and proprietary tools that allow us to make a number of significant adjustments. Adjustments are informed by periodic evaluation of vendor models and risk learning from comparing actual and modeled losses of catastrophe events, thus allowing for a view of risk that we believe is materially more complete and appropriate to the current risk landscape. Our peak natural catastrophe PMLs are measured using stochastic models that use hypothetical events of perils such as hurricanes and earthquakes. We define PML as the anticipated loss, taking into account contract terms and limits, caused by a single catastrophe affecting a broad contiguous geographical area, and are expressed at refine "return periods", such as "100-year events" and "250 year events". For example, a 100-year PML is the estimated loss to the current in-force portfolio from a single event which has a 1% probability of being exceeded in a twelve month period. Due to the uncertain nature of catastrophes and the hypothetical nature of vendor catastrophe models we use for estimating losses, there is no assurance that actual losses we experience within a time period will match the modeled PML. This approach to measuring catastrophe losses, however, is consistent with the best practice in the industry and employed by almost all of our peers.

16 Other Information Non-GAAP Measures 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 Supplementary Financial Information, 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.

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).

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 table below reconciles other underwriting expenses to general and administrative expenses, the most comparable GAAP financial measure: Other Underwriting Expense Ratio Other Underwriting Expense Ratio is a measure of the other underwriting expenses (net of third party fee income) incurred by the Company and is expressed as a percentage of net premiums earned. Loss Ratio Catastrophe Loss Ratio – current year is the catastrophe losses incurred by the company relating to the current year divided by net premiums earned. Catastrophe Loss Ratio – prior year development is the catastrophe losses incurred by the company relating to prior years divided by net premiums earned. Attritional Loss Ratio – current year is the attritional losses incurred by the company relating to the current year divided by net premiums earned. Attritional Loss Ratio – prior year development is the attritional losses incurred by the company relating to prior years divided by net premiums earned. Combined Ratio Combined Ratio is a measure of our underwriting profitability and is expressed as the sum of the loss and loss adjustment expense ratio, acquisition cost ratio and other underwriting expense ratio. A combined ratio under 100% indicates an underwriting profit, while a combined ratio over 100% indicates an underwriting loss.
