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, Ltd. (referred to herein as "Hamilton," the "Company," "we," "us" and "our") 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, 2024 and other subsequent periodic reports filed with the Securities and Exchange Commission and the following: • challenges from competitors, including those arising from industry consolidation and technological advancements; • unpredictable catastrophic events, global climate change and/or emerging claim and coverage issues; • our ability, or those of the third parties on which we rely, to ensure reserves are adequate to cover actual losses and to accurately evaluate underwriting risk, models, assessments and/or pricing of risks; • our ability to defend our intellectual property rights, including our proprietary technology platforms, to comply with our obligations under our license and technology agreements or to license rights to technology or data on reasonable terms; • the impact of risks associated with human error, fraud, model uncertainties, cybersecurity threats such as cyber-attacks and security breaches and our reliance on third-party information technology ("IT") systems that can fail or need replacement; • our ability to secure necessary credit facilities, or additional types of credit, on favorable terms or at all; • our limited financial and operating flexibility due to the covenants in our existing credit facilities; • our exposure to the credit risk of the intermediaries on which we rely; • our failure to pay claims in a timely manner or the need to sell investments under unfavorable conditions to meet liquidity requirements;
2 Basis of Presentation Special Note Regarding Forward-Looking Statements (continued) • downgrades, potential downgrades or other negative actions by rating agencies; • our ability to manage risks associated with macroeconomic conditions resulting from geopolitical and global economic events, including current or anticipated military conflicts, public health crises, terrorism, sanctions, rising energy prices, inflation and interest rates and other global events, including the instability from recent international trade policies; • the cyclical nature of the insurance and reinsurance business, which may cause the pricing and terms for our products to decline; • our results of operations potentially fluctuating significantly from period to period and not being indicative of our long-term prospects; • our ability to execute our strategy and to modify our business and strategic plan without shareholder approval; • our dependence on key executives, including the potential loss of Bermudian personnel, and our ability to attract qualified personnel, particularly in very competitive hiring conditions; • foreign operational risk such as foreign currency risk and political risk; • our ability to identify and execute opportunities for growth, to complete transactions as planned or realize the anticipated benefits of any acquisitions or other investments; • our management of alternative reinsurance platforms on behalf of investors in entities managed by Hamilton Strategic Partnerships; • our inability to control the allocations to, and/or the performance of, the Two Sigma Hamilton Fund, LLC (“TS Hamilton Fund” or "Two Sigma Hamilton Fund") investment portfolio and our limited ability to withdraw our capital accounts; • the impact of risks from conflicts of interest among Two Sigma Principals, LLC, Two Sigma Investments, LP (“Two Sigma”) and their respective affiliates affecting our business; • the historical performance of Two Sigma not being indicative of the future results of the TS Hamilton Fund’s investment portfolio and/or of our future results; • the impacts of risks associated with our investment strategy, including that such risks are greater than those faced by our competitors; • 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 ability to compete effectively in a heavily regulated industry in light of new domestic or international laws and regulations, including accounting practices, and the impact of new interpretations of current laws and regulations; • the suspension or revocation of our subsidiaries’ insurance licenses; • significant legal, governmental or regulatory proceedings; • our insurance and reinsurance subsidiaries’ ability to pay dividends and other distributions to us being restricted by law; • challenges related to compliance with the applicable laws, rules and regulations related to being a public company, which is expensive and time consuming; • the limited ability of investors to influence corporate matters due to our multiple class common share structure and the voting provisions of our Bye-laws; • the risk that anti-takeover provisions in our Bye-laws could discourage, delay, or prevent a change in control, even if the change in control would be beneficial to our shareholders; • the difficulties investors may face in protecting their interests and serving process or enforcing judgments against us in the United States; and • our current strategy does not include paying cash dividends on our Class B common shares in the near term.

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 that management uses to assess our operating results are considered non-GAAP financial measures under Regulation G and Item 10(e) of Regulation S-K, each promulgated by the SEC. We believe that these 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 directly comparable GAAP financial measures are included below. Operating Income (Loss) Attributable to Common Shareholders, Operating Income (Loss) Attributable to Common Shareholders per Common Share - Diluted and Operating Return on Average Common Shareholders' Equity - Annualized Operating income (loss) attributable to common shareholders, as used herein, differs from net income (loss) and other comprehensive income (loss) attributable to common shareholders, which we believe is the most directly comparable GAAP measure, by the exclusion of net realized and unrealized gains and losses on fixed maturity and short term investments, and net foreign exchange gains and losses. We also use operating income (loss) attributable to common shareholders to calculate operating income (loss) attributable to common shareholders per common share - diluted and operating return on average common shareholders' equity - annualized. We believe that operating income (loss) attributable to common shareholders, operating income (loss) attributable to common shareholders per common share - diluted and operating return on average common shareholders' equity - annualized are meaningful and useful to investors, analysts, rating agencies and others who use our financial information to evaluate our performance. The following tables are a reconciliation of: net income (loss) and other comprehensive income (loss) attributable to common shareholders to operating income (loss) attributable to common shareholders; net income (loss) and other comprehensive income (loss) attributable to common shareholders per common share - diluted to operating income (loss) attributable to common shareholders per common share - diluted; and return on average common shareholders' equity - annualized to operating return on average common shareholders' equity - annualized.

18 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), with other income (loss) being the most directly comparable GAAP financial measure.

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 directly 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 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. 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. 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.
