ARGO GROUP INTERNATIONAL HOLDINGS, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Business and Significant Accounting Policies

The accompanying Condensed Consolidated Financial Statements of Argo Group International Holdings, Inc. and its subsidiaries (“Argo Group,” “we,” “us,” “our” or the “Company”) have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X. Argo Group is an underwriter of specialty insurance products in the property and casualty market.

On November 16, 2023, we merged with Brookfield Wealth Solutions Ltd. (formerly known as Brookfield Reinsurance Ltd.), which resulted in a change to the Company’s ownership (the “Merger”). As a result of the Merger, and overall strategic shift, the Company changed its internal segments in a manner that caused the composition of its reporting segments to change in the fourth quarter of 2024. The Company’s reporting segments were realigned to three reportable segments—Casualty Lines, Specialty Lines, and Run-off Lines. Previously, the Company reported its operations under U.S Operations, International Operations and Run-off Lines, which primarily consisted of other liability policies that were issued in the 1960s, 1970s and into the 1980s, as well as the former risk-management business. For additional segment information, refer to Note 13, “Segment Information.” The Company has recast all applicable periods for comparability.

The preparation of interim financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities atas of the date of the financial statements and reported amounts of revenues and expenses during the reporting period. The major estimates reflected in our Condensed Consolidated Financial Statements include, but are not limited to, reserves for losses and loss adjustment expenses; reinsurance recoverables, including the reinsurance recoverables allowance for expected credit losses; fair value of investments and assessment of potential impairment, including the allowance for credit losses on fixed maturity securities; valuation of intangibles, including those identified as part of purchase accounting related to the Merger, and our deferred tax asset valuation allowance. Actual results could materially differ from those estimates. Certain financial information that is normally included in annual Condensed Consolidated Financial Statements, including certain financial statement footnotes, prepared in accordance with GAAP, is not required for interim reporting purposes and has been condensed or omitted. These statements should be read in conjunction with the Condensed Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2024 filed with the Securities and Exchange Commission ("SEC") (the “2024 Form 10-K”).

The interim financial information as of, and for the three and six months ended, ~~March~~June 3130, 2025 and 2024 is unaudited. However, in the opinion of management, the interim information includes all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of the results presented for the interim periods. The operating results for the interim periods are not necessarily indicative of the results to be expected for the full year. All material intercompany amounts have been eliminated in consolidation. Certain reclassifications have been made to financial information presented for prior years to conform to the current year’s presentation.

Argo Pro

In January 2025, certain subsidiaries of the Company entered into a Business Transfer Agreement, as amended and restated, with Core Specialty Insurance Holdings, Inc. (“Core”) and a Renewal Rights Agreement with Westfield Insurance Company, Westfield National Insurance Company, Westfield Select Insurance Company and Westfield Specialty Insurance Company (collectively, “Westfield”, and together with Core, collectively, the “Purchasers”), whereby the Purchasers purchased the renewal rights and related unearned premium reserves of the Company’s professional lines businesses. The Company entered into the transaction to align with strategic goals and continue to serve our broker partners through growth across other lines of business.

Allowance for Credit Losses

For fixed maturities with a decline in fair value below the amortized cost due to credit-related factors, an allowance is established for the difference between the estimated recoverable value and amortized cost with a corresponding charge to Net investment and other gains (losses) in the Condensed Consolidated Statements of Income (Loss). The allowance is limited to the difference between amortized cost and fair value. The estimated recoverable value is the present value of cash flows expected to be collected, as determined by management. The difference between fair value and amortized cost that is not associated with credit-related factors is recognized in the Condensed Consolidated Statements of Comprehensive Income (Loss). Accrued interest is excluded from the measurement of the allowance for credit losses.

When determining if a credit loss has been incurred, we may consider the historical performance of the security, available market information and security specific considerations such as the priority payment of the security. In addition, inputs used in our analysis include, but are not limited to, credit ratings and downgrades, delinquency rates, missed scheduled interest or principal payments, purchase yields, underlying asset performance, collateral types, modeled default rates, modeled severity rates, call/prepayment rates, expected cash flows, industry concentrations, and potential or filed bankruptcies or restructurings.

In cooperation with our investment managers, we evaluate for credit losses each quarter utilizing a bottom up review approach. At the security level, a determination is made as to whether a decline in fair value below the amortized cost basis is due to credit-related or noncredit-related factors. If we determine that all or a portion of a fixed maturity is uncollectible, the uncollectible amortized cost is written off with a corresponding reduction to the allowance for credit losses. If we collect cash flows that were previously written off, the recovery is recognized in Net investment and other gains (losses). We also consider whether we intend to sell an available-for-sale security or if it is more likely than not that we will be required to sell the security before recovery of its amortized cost. In these instances, a decline in fair value is recognized in Net investment and other gains (losses) in the Condensed Consolidated Statements of Income (Loss) based on the fair value of the security at the time of assessment, resulting in a new cost basis for the security.

For mortgage and private loans an allowance for credit losses is established at the time of origination or purchase, as necessary, and is updated each reporting period. Changes in the allowance for credit losses are recorded in Net investment and other gains (losses). This allowance reflects the risk of loss, even when that risk is remote, that is expected over the remaining contractual life of the loan. The allowance for credit losses considers available relevant information about the collectability of cash flows, including information about past events, current conditions, and reasonable and supportable forecasts of future economic conditions. For the three and six months ended June 30, 2025, the Company recognized $0.5 million and $0.5 million of additional mortgage loan allowances and $1.6 million and $3.1 million of additional private loan allowances, respectively.

Foreign Currency Exchange Forward Contracts

We entered into foreign currency exchange forward contracts primarily to manage currency exposure from our non-USD insurance operations. The currency forward contracts were carried at fair value in our Condensed Consolidated Balance Sheets in Accrued underwriting expenses and other liabilities and Other assets as of ~~March~~June 3130, 2025 and December 31, 2024, respectively. The net realized gains and (losses) are included in Net realized investment and other gains (losses) in our Condensed Consolidated Statements of Income (Loss).

Fair Value Measurements

Fair value is the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability, or in the absence of a principal market, the most advantageous market. Market participants are buyers and sellers in the principal (or most advantageous) market that are independent, knowledgeable, able to transact for the asset or liability and willing to transfer the asset or liability.

Valuation techniques consistent with the market approach, income approach and/or cost approach are used to measure fair value. The inputs of these valuation techniques are categorized into three levels.

•Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that can be accessed at the reporting date. We define actively traded as a security that has traded in the past seven days.

•Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. We receive one quote per instrument for Level 2 inputs.

•Level 3 inputs are unobservable inputs. Unobservable inputs reflect our own judgments about the assumptions market participants would use in pricing the asset or liability based on the best information available in the circumstances. Significant increases (decreases) in those inputs in isolation could result in a significantly lower (higher) fair value measurement.

To validate the fair value of investments in the Company’s Condensed Consolidated Financial Statements, we receive prices from multiple sources including third-party pricing services and our outside investment managers. Through a comparative analysis, the Company validates the reasonableness of its valuations. These prices are determined using observable market information such as dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the security’s terms and conditions, among other things. We have reviewed the processes used by the third-party providers for pricing the securities and have determined that these processes result in fair values consistent with GAAP requirements. In addition, we review these prices for reasonableness, and have not adjusted any prices received from the third-party providers as of ~~March~~June 3130, 2025 and December 31, 2024. A description of the valuation techniques we use to measure assets at fair value is as follows:

Fixed Maturities (Available-for-Sale) Levels 1 and 2:

•~~United~~U.S. ~~States~~ Treasury securities are typically valued using Level 1 inputs. For these securities, we obtain fair value measurements from third-party pricing services using quoted prices (unadjusted) in active markets at the reporting date.

•~~United~~U.S. ~~States~~ Government agencies, non-U.S. Government securities, obligations of states and political subdivisions, credit securities and foreign denominated government and credit securities are reported at fair value using Level 2 inputs. For these securities, we obtain fair value measurements from third-party pricing services. Observable data may include dealer quotes, market spreads, yield curves, live trading levels, trade execution data, credit information and the security’s terms and conditions, among other things.

•Asset and mortgage-backed securities and collateralized loan obligations are reported at fair value using Level 2 inputs. For these securities, we obtain fair value measurements from third-party pricing services. Observable data may include dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the security’s terms and conditions, among other things.

Table of Contents

Fixed Maturities (Available-for-Sale) Level 3: We own term loans and asset-back securities that are valued using unobservable inputs.

Equity Securities Level 1: For these securities, we obtain fair value measurements from a third-party pricing service using quoted prices (unadjusted) in active markets at the reporting date.

Equity Securities Level 3: We own certain equity securities that are reported at fair value using Level 3 inputs. The valuation techniques for these securities include the following:

•Fair value measurements for an investment in an equity fund obtained by applying final prices provided by the administrator of the fund, which is based upon certain estimates and assumptions.

•Fair value measurements from brokers and independent valuation services, both based upon estimates, assumptions and other unobservable inputs.

Table of Contents

Short-term Investments: Short-term investments are principally reported at fair value using Level 1 inputs, with the exception of short-term corporate and governmental bonds reported at fair value using Level 2 inputs as described in the fixed maturities section above. Values for the investments categorized as Level 1 are obtained from various financial institutions as of the reporting date.

Other ~~investments~~Investments: Other investments include private securities for which we have elected the fair value option of accounting, and are valued using unobservable Level 3 inputs.

Derivative assets: As a result of the Company’s commutation of the assumed reinsurance agreement with Riverstone Holdings Limited, the Company classified the ceded reserves on the Malta business as a derivative in accordance with ASC 815. As the ceded reserves are shorter term in nature, management has concluded that the fair value is equivalent to its carrying value, resulting in no impact to earnings.

Derivative liabilities: We enter into foreign currency forward contracts to hedge our investment exposure to foreign currencies. These derivatives are carried at fair value using Level 2 inputs, primarily observable foreign exchange rates at the end of the period.

As of ~~March~~June 3130, 2025 and December 31, 2024, we did not have any financial assets or financial liabilities measured at fair value on a nonrecurring basis.

The Company holds certain investments at cost, less an allowance for expected credit losses, on the Condensed Consolidated Balance Sheets. The fair value of the Company’s investments is estimated using a discounted cash flow analysis. Due to the level of unobservable inputs factored into the estimation of fair value, the valuation would be categorized as Level 3. The cost and estimated fair value of these investments were:

Reserves for losses and LAE represent the estimated indemnity cost and related adjustment expenses necessary to investigate and settle claims. Such estimates are based upon individual case estimates for reported claims, estimates from ceding companies for reinsurance assumed and actuarial estimates for losses that have been incurred but not yet reported to the insurer. Any change in probable ultimate liabilities is reflected in current operating results.

The impact from the unfavorable (favorable) development of prior accident years’ loss and LAE reserves on each reporting segment is presented below:

	For the Three Months Ended
	For the Six Months Ended June 30,
	March 31,
(in millions)	2025		2024
Casualty Lines	$	020.89	$	04.72
Specialty Lines	0(19.17)		05.73
Run-off Lines	0.1.4		2356.41
Total unfavorable (favorable) prior-year development	$	12.06	$	2465.86

The following describes the primary factors behind each segment’s net prior accident year loss reserve development for the ~~three~~six months ended ~~March~~June 3130, 2025 and 2024:

•For the ~~three~~six months ended ~~March~~June 3130, 2025, net unfavorable development ~~primarily~~ within Casualty Lines primarily related to ~~involuntary~~construction ~~pools~~ and ~~other~~Bermuda ~~workers’~~Casualty ~~compensation~~ exposures, largely offset by favorable development within Specialty Lines primarily associated with garage and inland marine business.

•For the ~~three~~six months ended ~~March~~June 3130, 2024, net unfavorable development primarily related to movements within Run-off ~~lines~~Lines on large individual surety claims and assumed business from our former Malta operations, ArgoGlobal Holdings (Malta) Ltd., which was sold in 2022.

Our reserves represent the best estimate of our ultimate liabilities, based on currently known facts, current law, current technology and reasonable assumptions where facts are not known. Due to the significant uncertainties and related management judgments, there can be no assurance that future favorable or unfavorable loss development, which may be material, will not occur.

Debt. AtAs ~~March~~of June 3130, 2025 and December 31, 2024, the fair value of our debt instruments is determined using both Level 1 and Level 2 inputs, as previously defined in Note 3, “Investments.”

We receive fair value prices for similar financial instruments being traded in active markets. These prices are determined using observable market information such as publicly traded quoted prices, and trading prices for similar financial instruments actively being traded in the current market. We have reviewed the processes used by third-party providers for pricing these instruments and have determined that they result in fair values consistent with GAAP requirements. In addition, we review these prices for reasonableness, and have not adjusted any prices received from the third-party providers as of ~~March~~June 3130, 2025 and December 31, 2024. A description of the valuation techniques we use to measure these liabilities at fair value is as follows:

Senior Unsecured Fixed Rate Notes Level 1:

•Our senior unsecured fixed rate notes are valued using Level 1 inputs. For these securities, we obtain fair value measurements from a third-party pricing service using quoted prices (unadjusted) in active markets at the reporting date.

Junior Subordinated Debentures Level 2:

•Our trust preferred debentures and subordinated debentures are typically valued using Level 2 inputs. For these securities, we obtain fair value measurements using quoted prices for similar securities being traded in active markets at the reporting date, as our specific debt instruments are less frequently traded.

A summary of our financial instruments whose carrying value did not equal fair value is shown below:

The Company is incorporated under the laws of the U.S. We have subsidiaries based in the U.S. that are subject to U.S. tax laws. Under current law, these subsidiaries are taxed at the applicable corporate tax rates. Beginning January 1, 2024, our U.S. subsidiaries file a consolidated U.S. federal income tax return with BAMR US Holdings LLC, a subsidiary of Brookfield Wealth Solutions Ltd.

Argo Re Ltd., a Bermuda domiciled entity, is a U.S. taxpayer through a section 953(d) voluntary election under the Internal Revenue Code of 1986, as amended. Argo Re Ltd. pre-tax income (loss) and tax provision (benefit) is reported in the U.S.

We also have operations in Italy and United Kingdom which are subject to income taxes imposed by the jurisdiction in which they operate. Furthermore, we have an operation in Barbados which is not subject to income tax under the laws of that country.

On August 16, 2022, U.S. legislation referred to as the Inflation Reduction Act of 2022 was enacted. This legislation enacted a new Corporate Alternative Minimum Tax (“CAMT”) and Excise Tax on Repurchases of Corporate Stock. The Company has determined as of the period ended ~~March~~June 3130, 2025, that it is subject to CAMT. The recognition of applicable CAMT is reported on a consolidated basis with Brookfield Wealth Solutions Ltd. The Company is not subject to Excise Tax on Repurchases of Corporate Stock.

Our expected income tax provision computed on pre-tax income (loss) at the weighted average tax rate has been calculated as the sum of the pre-tax income (loss) in each jurisdiction multiplied by that jurisdiction’s applicable statutory tax rate. For the three and six months ended June 30, 2025 and 2024, pre-tax income (loss) attributable to our operations and the corresponding operations’ effective tax rates were as follows:

(1) Pre-tax income (loss) for the respective year was less than $0.1 million.

Our gross deferred tax assets are supported by taxes paid in previous periods, reversal of taxable temporary differences and recognition of future taxable income. Management regularly evaluates the recoverability of the deferred tax assets and makes any necessary adjustments to them based upon any changes in management’s expectations of future taxable income. Realization of deferred tax assets is dependent upon our generation of future taxable income sufficient to recover tax benefits that cannot be recovered from taxes paid in the carryback period, generally for our U.S. property and casualty insurers two years for net operating losses and for all our U.S. subsidiaries three years for capital losses. If a company determines that any of its deferred tax assets will not result in future tax benefits, a valuation allowance must be established for the portion of these assets that are not expected to be realized. For three months ended March 31, 2025, the net change in valuation allowance for deferred tax assets was a decrease of $1.3 million related to the reduction of net operating loss carryforwards incurred in the United Kingdom. Existing valuation allowances pertain to Internal Revenue Code Section 382 limited net operating loss carryforwards within the United States and cumulative losses incurred in the United Kingdom and Italy. Based upon a review of all positive and negative evidence, our management concluded that it is more-likely-than-not that $79.3 million of our deferred tax assets will be realized. Should our future income deviate from our present income estimates, the Company’s realization assessment may differ from our current conclusion.

For any uncertain tax positions not meeting the “more-likely-than-not” recognition threshold, accounting standards require recognition, measurement and disclosure in the Company’s Condensed Consolidated Financial Statements. The Company does not have any recognized uncertain tax positions for federal or state income tax liability for the three months ended March 31, 2025.

12. Commitments and Contingencies

Legal Actions

Argo Group’s subsidiaries are parties to legal actions incidental to their business. As of ~~March~~June 3130, 2025, management believes that the resolution of these matters would not materially affect our financial condition or results of operations.

Federal Securities Class Action

The Police & Fire Retirement System City of Detroit v. Argo Group International Holdings, Inc., et al., No. 22-cv-8971 (S.D.N.Y.)

On October 20, 2022, a securities class action lawsuit was filed in the United States District Court for the Southern District of New York against the Company and certain of its current and former officers, alleging securities fraud violations under sections 10(b) and 20(a) of the Securities Exchange Act of 1934. Plaintiff alleges that from February 13, 2018 through August 9, 2022, the defendants made false and misleading statements concerning the Company’s reserves and underwriting standards. On January 18, 2023, U.S. District Judge Lewis A. Kaplan granted the Police and Fire Retirement System City of Detroit and the Oklahoma Law Enforcement Retirement System’s joint motion for appointment as lead plaintiff. On March 27, 2023, lead plaintiffs filed an amended class action complaint. On May 26, 2023, the defendants moved to dismiss the amended class action complaint. On July 13, 2023, lead plaintiffs filed an opposition to such motion, after which defendants filed a reply on August 14, 2023. On December 12, 2024, the court granted defendants’ motion to dismiss. The period to appeal this decision expired on January 16, 2025, and accordingly, we consider this matter to be closed.

Bermuda Appraisal Petitions

In April 2023, appraisal petitions were filed in the Supreme Court of Bermuda (the “Court”) relating to the acquisition of the Company by Brookfield Wealth Solutions Ltd. for $30.00 per share (the “Transaction Price”) that closed on November 16, 2023.

Table of Contents

The petitions were filed by certain persons who were shareholders of the Company at such time pursuant to Section 106(6) of the Bermuda Companies Act, and are captioned Corbin Erisa Opportunity Fund, Ltd. v. Argo Group International Holdings, Ltd., Corbin Opportunity Fund, L.P. v. Argo Group International Holdings, Ltd., Fourworld Event Opportunities, LP v. Argo Group International Holdings, Ltd., Fourworld Global Opportunities Fund, Ltd. v. Argo Group International Holdings, Ltd., Fourworld Special Opportunities Fund, LLC v. Argo Group International Holdings, Ltd., and FW Deep Value Opportunities Fund I, LLC v. Argo Group International Holdings, Ltd.

Section 106(6) of the Companies Act permits a shareholder of a Bermuda company, such as the Company prior to the Company’s redomestication to the State of Delaware, to petition the Court for a determination of the fair value of the Company’s shares if they are not satisfied with the Transaction Price.

On January 3, 2024, the Company filed a summons to stay the appraisal action pending judgment of the Judicial Committee of the Privy Council in the matter captioned “In re matter of Jardine Strategy Holdings Limited Case No: Civ/2022/14-31.” Hearings were held on July 9, 2024 and July 18, 2024. On December 3, 2024, the Court denied the stay application. The Court convened a Directions Hearing on May 1 and 2, 2025 and heard arguments from the parties and proposals on the scope of discovery and schedule for trial. The Judge did not rule at the hearing but said she plans to issue a ruling in the near future. The Company intends to continue to defend this matter vigorously.

Capital Shield Action

In April 2025, Capital Shield, Inc. (“Plaintiff”) brought this action in the U.S. District Court Middle District of Florida against Amwins Access Insurance Services, LLC (“Amwins”) and Peleus Insurance Company (“Peleus”) alleging breach of contract claims against Amwins and further alleging Amwins and Peleus violated Section I of the Sherman Act. The allegations arise out of a Program Administrator Agreement between Amwins and Plaintiff in which Peleus was to act as an underwriter for the program. Plaintiff alleges that Peleus colluded with Amwins to restrain trade in violation of Section 1 of the Sherman Act, and this collusion deprived the insurance-buying public of the opportunity to purchase Plaintiff's product. Each of Amwins and Peleus has filed a motion to dismiss the Sherman Act claim (the only claim against Peleus).

Contractual Commitments

We have contractual commitments to invest up to $~~211~~165.9 million related to our limited partnership investments atas ~~March~~of June 3130, 2025, as further disclosed in Note 3, “Investments.” These commitments will be funded as required by the partnership agreements which can be called to be fulfilled at any time. Additionally, the Company has commitments to fund up to $~~130~~300.47 million related to various other investments, including debt and equity securities, term loans and mortgage loans.

13. Segment Information

We are primarily engaged in underwriting property and casualty insurance and reinsurance. As a result of the Company’s merger with Brookfield Wealth Solutions Ltd., and overall strategic assessment of the business, the Company changed its internal segments in a manner that caused the composition of its reporting segments to change in the fourth quarter of 2024. The Company’s reporting segments were realigned to three reportable segments—Casualty Lines, Specialty Lines, and Run-off Lines. The Run-off Lines segment is for certain products that we no longer underwrite. The Company has recast all applicable periods for comparability.

We consider many factors, including the nature of each segment’s insurance and reinsurance products, production sources, distribution strategies and the regulatory environment, in determining how to aggregate operating segments. Transactions between segments are reported in the segment that initiated the transaction.

Our reporting segments consist primarily of the following products:

•Casualty Lines: Argo Construction, Argo Environmental, Argo Casualty, Rockwood, Bermuda Casualty, and Bermuda Insurance and Europe

•Specialty Lines: Specialty Programs and Fronting, Colony Specialty Garage, Argo Inland Marine, and Bermuda Property

•Run-off Lines: Liability and surety policies

We have identified our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), as our Chief Operating Decision Maker (“CODM”).

Table of Contents

In evaluating the operating performance of our segments, the CODM assesses the segments’ performance by using each segments’ segment operating income (loss) consistent with GAAP measures.

The CODM uses segment operating income (loss) for each segment predominantly in the quarterly/annual budget and forecasting process. The CODM considers budget-to-actual variances on a quarterly basis for the profit measure when making decisions about the allocation of operating and capital resources to each segment. The CODM also uses segment operating income (loss) for each segment for evaluating pricing strategy and to assess the performance of each segment by comparing the results of each segment with one another and in determining the compensation of certain employees.

Realized investment and other gains (losses) are reported as a component of Corporate and Other, as decisions regarding the acquisition and disposal of securities reside with the corporate investment function and are not under the control of the individual business segments.

Revenue and segment operating income (loss) for each segment were as follows:

InLoss ~~determining appropriate reserve levels for the three months ended March 31, 2025, we maintained the same general processes~~ and ~~disciplines~~Loss ~~that~~Adjustment were used to set reserves at prior reporting dates. No significant changes in methodologies were made to estimate the reserves since the last reporting date; however, at each reporting date we reassess the actuarial estimate of the reserve for loss and loss adjustment expenses and record our best estimate. Consistent with prior reserve valuations, as claims data becomes more mature for prior accident years, actuarial estimates were refined to weigh certain actuarial methods more heavily in order to respond to any emerging trends in the paid and reported loss data. Pricing, reinsurance costs, legal environment, general economic conditions including changes in inflation and trade policies and many other factors impact our ultimate loss estimates. Refer to segment results for specific factors impacting our current accident year loss ratios.Expenses

Catastrophe losses for the six months ended June 30, 2025 of $14.7 million (3.3% percentage points) were attributable to losses associated with U.S. storms compared to $13.1 million (2.2% percentage points) for the same period ended June 30, 2024.

The net unfavorable prior-year reserve development for the three months ended June 30, 2025 of $1.6 million was due to $20.1 million from Casualty Lines and $1.3 million from Run-off Lines, partially offset by favorable development of $19.8 million from Specialty Lines.

Underwriting, acquisition and general expenses includes amortization expense of value of business acquired (“VOBA”) and other intangible assets. The ~~increase~~decrease in the expense ratio for the three and six month periods was primarily driven by a lower acquisition expense ratio as a result of business mix due to the ~~reduction~~businesses input ~~net~~into ~~earned~~run-off ~~premiums~~having ~~exceeding~~higher ~~our~~acquisition ~~reduction~~costs inand ~~operating~~lower ~~expenses~~non-acquisition costs.

Income Tax Provision (Benefit)

The consolidated income tax provision represents the income tax expense or benefit associated with our operations based on the tax laws of the jurisdictions in which we operate. Therefore, the provision for income taxes represents taxes on net income for our ~~United States~~U.S., United Kingdom, Barbados, and Italy operations. The Company recorded an income tax provision of $816.0 million and $24.3 million for the three and six months ended ~~March~~June 3130, 2025. This is compared to the income tax provision of $15.6 million and $7.2 million for the same ~~period~~periods ended 2024.

The effective tax rate was 21.64% and 21.5% for the three and six months ended ~~March~~June 3130, 2025 compared to the effective tax rate of 530.6% and 15.8% for the same periods ended 2024. For the three and six months ended ~~March~~June 3130, 2025, the effective tax rate is aligned with statutory tax rates. For the three and six months ~~ending~~ended ~~March~~June 3130, 2024, the effective tax rate was impacted by prior period adjustments. Excluding the prior period adjustments, the effective tax rate for the ~~period~~three ~~ending~~and ~~March~~six months ended June 3130, 2024 was more aligned with statutory tax rates.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the U.S. The OBBBA includes provisions that allow for the immediate expensing of domestic research and development expenses, immediate expensing of certain capital expenditures, and other changes to the U.S. taxation profits derived from foreign operations. The Company continues to evaluate the impact the new legislation will have on our estimated annual effective tax rate and cash tax position.

Segment Results

As a result of the Company’s merger with Brookfield Wealth Solutions Ltd, and overall strategic assessment of the business, the Company changed its internal segments in a manner that caused the composition of its reporting segments to change in the fourth quarter of 2024. The Company’s reporting segments were realigned to three reportable segments—Casualty Lines, Specialty Lines, and Run-off Lines. The Company has recast all applicable periods for comparability.

Net Earned Premiums

Net earned premiums were $~~144~~156.14 million and $~~136~~300.5 million for the three and six months ended ~~March 31~~June 30, 2025, respectively, and $133.2 million and $269.7 million for the three and six months ended June 30, 2024, respectively. Premium growth was attributable to our casualty, construction, environmental and Bermuda business units and driven primarily by lower ceded earned premiums resulting from changes to our reinsurance structure.

The loss ~~ratio~~ratios for the three and six months ended ~~March 31~~June 30, 2025 ~~was~~were 7533.3% and 53.9% as compared to 6370.49% and 67.1% for the three and six months ended ~~March~~June 3130, 2024. The decrease in both periods compared to 2024 is driven by net favorable prior-year reserve development.

Net prior-year reserve development was $0.1 million unfavorable for the three months ended March 31, 2025, as compared to $0.7 million unfavorable for the same period in 2024. The net unfavorable prior year reserve development for the three months ended March 31, 2025 was primarily related to involuntary pools, offset by small favorable movements in other lines.37

Catastrophe losses for the three months ended March 31, 2025 were $7.2 million. Catastrophe losses for the three months ended March 31, 2024 were $5.8 million. Catastrophe losses for both 2025 and 2024 periods were mainly due to U.S. storms.

Underwriting, Acquisition and General Expenses

Underwriting, acquisition and general expenses were $17.6 million for the three months ended March 31, 2025, as compared to $11.9 million for the three months ended March 31, 2024. The increase was driven by a higher acquisition costs partially offset by lower operating costs from personnel expense reductions.

The expense ratio was 28.9% for the three months ended March 31, 2025 and 17.9% for the same period in 2024. The increase in the overall expense ratio was due to the decline in net earned premiums exceeding our reduction in operating expenses.

Liquidity and Capital Resources

Cash Flows

The Company’s future cash flows largely depend on the availability of dividends or other statutorily permissible payments from subsidiaries. The ability to pay such dividends is limited by the applicable laws and regulations of the various countries and states in which these subsidiaries operate, including, among others, Bermuda.

The primary sources of our cash inflows are premiums, reinsurance recoveries, proceeds from sales and redemptions of investments and investment income. The primary cash outflows are claim payments, loss adjustment expenses, reinsurance costs, underwriting, acquisition and overhead expenses, interest expense, purchases of investments, payment of preferred dividends and income taxes. Management believes that cash inflows are sufficient to cover cash outflows in the foreseeable future. We have access to additional sources of liquidity should the need for additional cash arise.

Cash provided by or used in operating activities can fluctuate due to timing differences in the collection of premiums and reinsurance recoveries and the payment of losses and expenses. For the ~~three~~six months ended ~~March~~June 3130, 2025 and 2024, net cash used in operating activities was $505.6 million compared to net cash used in operating activities of $1380.72 million, respectively. The ~~decrease~~increase in cash flows from operating activities in 2025 compared to 2024 was attributable to various fluctuations within our operating activities, and primarily related to the timing of reinsurance payments and recoveries, claim payments and premium cash receipts in the respective periods. The decrease in premium is a result of a strategic reassessment of our various lines of business.

For the ~~three~~six months ended ~~March~~June 3130, 2025, net cash provided by investing activities was $26304.42 million compared to net cash used in investing activities of $~~512~~430.96 million for the same period in 2024. Net cash provided by investing activities in 2025 was mainly the result of sales and maturities of fixed maturity investments and proceeds from mortgage loans and private loans, partially offset by purchases of ~~short-term investments,~~ fixed maturity investments, ~~and~~ private loan investments and equity securities. Net cash used in investing activities in 2024 was mainly the result of purchases of short-term investments, private loan investments, and mortgage loans offset by net proceeds from fixed ~~maturities~~maturity investments.

For the ~~three~~six months ended ~~March~~June 3130, 2025, net cash used in financing activities was $25.63 million compared to $~~197~~194.47 million net cash provided by in 2024. Net cash used in financing activities in 2025 was driven by the payment of cash dividends to preferred stockholders. Net cash provided by financing activities in 2024 was driven by the issuance of our shares of common ~~shares~~stock to Brookfield ~~Reinsurance~~Wealth ~~and~~Solutions ~~borrowings~~Ltd. ~~under~~(formerly ~~our~~known ~~revolving~~as ~~credit~~Brookfield ~~facility~~Reinsurance Ltd.).

Revolving Credit Facility

On February 21, 2024, the Company entered into Amendment No. 6 (“Amendment No. 6”) of the Credit Agreement with the financial institutions party thereto as lenders and JPMorgan Chase Bank, N.A., individually as a lender and as administrative agent (the “Credit Agreement”). Amendment No. 6, among other things, replaced the minimum Tangible Net Worth covenant in the Credit Agreement with a minimum Consolidated Net Worth. The Consolidated Net Worth covenant is tested at the end of each fiscal quarter and has been set at an amount equal to the sum of (i) $872.0 million plus (ii) 50% of positive net income for each fiscal quarter ending after December 31, 2023 plus (iii) 50% of net proceeds received from the issuance and sale of certain equity interests after December 31, 2023.

On February 22, 2024, the Company borrowed $100.0 million from the revolving credit facility and elected a one-month term and interest option, under the terms of the Credit Agreement. The loan had been renewed using the one-month option until May 29, 2024, when the Company repaid the $100.0 million borrowed under the revolving credit facility. The facility was subsequently terminated on June 4, 2024. On June 4, 2024, the Company was named as a party under Brookfield Wealth Solutions Ltd.’s $1.2 billion revolving credit facility.

Letter of Credit Facilities

On ~~March~~June 3130, 2025, letters of credit totaling $3128.45 million were outstanding, of which $21.56 million were issued against the committed secured bilateral letter of credit facility and $96.9 million were issued against the uncommitted, secured bilateral letter of credit facility. Collateral with a market value of $4237.63 million was pledged to these banks as security against these letters of credit.

Condensed Consolidating Financial Information

Supplemental Guarantor Financial Information

In September 2012, the Company (the “Parent Guarantor”), through ~~its~~Argo Group US, Inc. (the “Subsidiary Issuer”), issued $143.8 million aggregate principal amount of the Subsidiary Issuer’s 6.5% Senior Notes due September 15, 2042 (the “Notes”). The Notes are unsecured and unsubordinated obligations of the Subsidiary Issuer and rank equally in right of payment with all of the Subsidiary Issuer’s other unsecured and unsubordinated debt. The Notes are guaranteed on a full and unconditional senior unsecured basis by the Parent Guarantor. The Notes may be redeemed, for cash, in whole or in part at the Subsidiary Issuer’s option, at any time and from time to time, prior to maturity at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued but unpaid interest on the principal amount being redeemed to, but not including, the redemption date. The Company’s ability to repay the Notes largely depends on the availability of dividends or other statutorily permissible payments from subsidiaries.

This summarized financial information has been prepared in accordance with Regulation S-X Rule 13-01, Financial Disclosures about Guarantors and Issuers of Guaranteed Securities and is not intended to present the financial position or results of operations of the obligor group in accordance with U.S. GAAP.

Recent Accounting Standards and Critical Accounting Estimates

New Accounting Standards

The discussion of the adoption and pending adoption of recently issued accounting policies is included in Note 1, “Recent Accounting Pronouncements” in the Company’s 2024 Form 10-K.

Refer to “Critical Accounting Estimates” in the Company’s 2024 Form 10-K for information on accounting estimates and policies that we consider critical in preparing our Condensed Consolidated Financial Statements. These policies include significant estimates made by management using information available at the time the estimates were made. However, these estimates could change materially if different information or assumptions were used.

There have been no material changes to our critical accounting estimates described in our 2024 Form 10-K.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

We believe that we are principally exposed to four types of market risk: interest rate risk, credit risk, equity price risk and foreign currency risk.

Interest Rate Risk

Our primary market risk exposure on fixed maturity investments relates to interest rate risk and the changes in interest rates. Fluctuations in interest rates have a direct impact on the fair value of these securities. As interest rates rise, the fair value of our fixed maturity portfolio falls, and the converse is also true. We manage interest rate risk through an active portfolio management strategy that involves the selection of investments with appropriate characteristics such as duration, yield, currency and liquidity that are tailored to the anticipated cash outflow characteristics of our liabilities. A significant portion of our investment portfolio matures each year, allowing for reinvestment at current market rates. The model duration of the assets comprising our fixed maturity investment portfolio was 2.6467 years and 2.66 years atas ~~March~~of June 3130, 2025 and December 31, 2024, respectively.

Credit Risk

We have exposure to credit risk on losses recoverable from reinsurers and receivables from insureds. Our controls to mitigate this risk include limiting our exposure to any one counterparty, evaluating the financial strength of our reinsurers, canceling policies, generally requiring minimum credit ratings and in certain cases receiving collateral from our reinsurers and insureds.

We also have exposure to credit risk in our investment holdings. Our risk management strategy and investment policy attempts to mitigate this risk by primarily investing in debt instruments of high credit quality issuers, limiting credit concentration, monitoring the credit quality of issuers and counterparties and diversifying issuers. The weighted average rating of our fixed maturity investments was ~~AA-~~A+ and A+ with 96.67% and ~~A with~~ 97.0% rated investment grade or better (BBB- or higher) atas ~~March~~of June 3130, 2025 and December 31, 2024, respectively.

We review our investments to identify and evaluate those that may have credit impairments on a quarterly basis, considering the historical performance of the security, available market information, and credit ratings, among other things. For fixed maturity securities, the review includes consideration of current ratings and actions of major rating agencies (Standard & Poor's, Moody's and Fitch). If a security has two ratings, the lower rating is used. If a security has three ratings, the middle rating is used. The following table reflects the credit quality of our fixed maturity portfolio atas ~~March~~of June 3130, 2025:

Our portfolio also includes alternative investments with a carrying value atas ~~March~~of June 3130, 2025 and December 31, 2024 of $~~573~~572.42 million and $577.4 million (1314.97% and 14.1% of total invested assets), respectively. We may invest in both long and short equities, corporate debt securities, currencies, real estate, commodities and derivatives. We attempt to mitigate our risk by selecting managers with extensive experience, proven track records and robust controls and processes. We also attempt to mitigate our risk by diversifying through multiple managers and different types of assets and asset classes.

Mortgage loans add portfolio diversification. These assets typically afford credit protections through covenants and deeper due diligence given information access. We also monitor debt service coverage ratios and loan-to-value ratios in our assessment of credit risk and exposure.

Equity Price Risk

We hold a diversified portfolio of equity securities with a fair value of $~~431~~534.38 million and $413.0 million (1013.57% and 10.1% of total invested assets) atas ~~March~~of June 3130, 2025 and December 31, 2024, respectively. Our equity securities are exposed to equity price risk which is defined as the potential for loss in fair value due to a decline in equity prices. We believe the diversification of our equity securities among various industries, market segments and issuers, as well as the use of multiple outside investment managers, mitigates our exposure to equity price risk.

Foreign Currency Risk

We have exposure to foreign currency risk in our insurance contracts and invested assets. We attempt to manage our foreign currency risk by seeking to match our liabilities under insurance and reinsurance contracts that are payable in currencies other than the U.S. Dollar with cash and investments that are denominated in such currencies. We also use foreign exchange forward contracts to attempt to mitigate this risk. For the three and six months ended ~~March~~June 3130, 2025, we recognized $08.07 million ~~of gross gains~~ and $412.18 million of gross losses from foreign exchange contracts~~, for a net loss of $4~~.1 ~~million.~~ For the three and six months ended ~~March~~June 3130, 2024, we recognized $21.6 million and $3.0 million of gross gains and $2.70 million and $3.6 million of gross losses from foreign exchange contracts, for a net loss of $0.14 million and $0.6 million, respectively. The net losses are recorded in the Net investment and other gains (losses) in the Condensed Consolidated Statements of Income (Loss).

Item 4. Controls and Procedures

Argo Group, under the supervision and with the participation of its management, including the Chief Executive Officer and the Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (“Exchange Act”) as of the end of the period covered by this report. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the disclosure controls and procedures were effective as of ~~March~~June 3130, 2025, at the reasonable assurance level to ensure that information required to be disclosed by Argo Group in the reports filed or submitted under the Exchange Act are recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Change in Internal Control Over Financial Reporting

There were no changes in internal control over financial reporting made during the quarter ended ~~March~~June 3130, 2025 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

We are subject to laws, policies and regulations relating to sanctions, anti-corruption and money laundering, the violation of which could adversely affect our operations.

Our activities are subject to applicable economic and trade sanctions, money laundering regulations, and anti-corruption laws in the jurisdictions where we operate, including Bermuda, the U.K. and the European Community and the U.S., among others. For example, we are subject to The Bribery Act, 2016 of Bermuda, the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act 2010, which, among other matters, generally prohibit corrupt payments or unreasonable gifts to foreign governments or officials. New sanction regimes may be initiated, or existing sanctions expanded, at any time, which can impact our business activities. In addition, changes in international trade policies and tariffs by the U.S. and other countries, particularly large trading partners like Canada, China, and Mexico, could (i) impact our claims severity across multiple lines of business and cause adverse reserve development by increasing costs for materials and parts used in claims involving real property and (ii) negatively affect our investments' fair value and/or our level of investment income.

We believe we maintain strong oversight and control through our experienced Co-Chief Investment Officers and internal investment teams, the deployment of our Code of Conduct and Business Ethics and associated policies and procedures including the Company’s whistleblower policies, and continuous education and training programs. However, although we have in place systems and controls designed to ensure compliance with applicable laws, policies and regulations, there is a risk that those systems and controls will not always be effective to achieve full compliance. It is also possible that an employee or intermediary could fail to comply with applicable laws, policies and regulations. Failure to accurately interpret or comply with or obtain appropriate authorizations and/or exemptions under such laws, policies or regulations could subject us to investigations, criminal sanctions or civil remedies, including fines, injunctions, loss of an operating license and other sanctions, all of which could damage our business or reputation, and have a material adverse effect on our financial condition and results of operations.
