Cautionary Statement Regarding Forward-Looking Statements

The Private Securities Litigation Reform Act of 1995 (the Act) provides a "safe harbor" to encourage companies to provide prospective information, as long as those statements are identified as forward-looking and are accompanied by meaningful cautionary statements identifying important factors that could cause actual results to differ materially from those included in the forward-looking statements. Certain information contained in this quarterly report on Form 10-Q (including certain statements in the consolidated financial statements and related notes and Management's Discussion and Analysis), or in any other written or oral statements made by us in communications with the financial community or contained in documents filed with the Securities and Exchange Commission (SEC), may be considered forward-looking statements within the meaning of the Act. Forward-looking statements are those not based on historical information, but rather relate to our outlook, future operations, strategies, financial results, or other developments. Forward-looking statements speak only as of the date made. We undertake no obligation to update these statements, even if made available on our website or otherwise. These statements may be made directly in this document or may be made part of this document by reference to other documents filed by us with the SEC, a practice which is known as "incorporation by reference." You can find many of these statements by looking for words such as "will," "may," "should," "could," "believes," "expects," "anticipates," "estimates," "plans," "assumes," "intends," "projects," "goals,” "objectives," or similar expressions in this document or in documents incorporated herein.

Cautionary Statement Regarding Forward-Looking Statements - Continued

These forward-looking statements are subject to numerous assumptions, risks, and uncertainties, many of which are beyond our control. We caution readers that the following factors, in addition to other factors mentioned from time to time, may cause actual results to differ materially from those contemplated by the forward-looking statements:

•Fluctuation in insurance reserve liabilities, claim payments, and pricing due to changes in claim incidence, recovery rates, mortality and morbidity rates, and policy benefit offsets due to, among other factors, the rate of unemployment and consumer confidence, the emergence of new diseases, epidemics, or pandemics, new trends and developments in medical treatments, the effectiveness of our claims operational processes, and changes in governmental programs.

•Sustained periods of low interest rates.

•Unfavorable economic or business conditions, both domestic and foreign, that may result in decreases in sales, premiums, or persistency, as well as unfavorable claims activity or unfavorable returns on our investment portfolio.

•Changes in, or interpretations or enforcement of, laws and regulations.

•A cybersecurity attack or other security breach resulting in compromised data or the unauthorized acquisition of confidential data.

•The failure of our business recovery and incident management processes to resume our business operations in the event of a natural catastrophe, cybersecurity attack, or other event.

•Increased competition from other insurers and financial services companies due to industry consolidation, new entrants to our markets, or other factors.

•Investment results, including, but not limited to, changes in interest rates, defaults, changes in credit spreads, impairments, and the lack of appropriate investments in the market which can be acquired to match our liabilities.

•Ineffectiveness of our derivatives hedging programs due to changes in forecasted cash flows, the economic environment, counterparty risk, ratings downgrades, capital market volatility, collateral requirements, changes in interest rates, and/or regulation.

•Our ability to develop digital capabilities or execute on our technology systems upgrades or replacements.

•Our use of artificial intelligence technology, as well as changes in artificial intelligence laws and regulations.

•The impact of pandemics and other public health issues on our business, financial position, results of operations, liquidity and capital resources, and overall business operations.

•Changes in our financial strength and credit ratings.

•The ability of our reinsurers to meet their obligations to us and availability of reinsurance in the market.

•Our ability to hire and retain qualified employees.

•Disruptions to our business or our ability to access data caused by the use and reliance on third-party vendors, including vendors providing web and cloud-based applications.

•Ability to generate sufficient internal liquidity and/or obtain external financing.

•Damage to our reputation due to, among other factors, regulatory investigations, legal proceedings, social issues, third-party vendors, external events, and/or cyber or other information security incidents.

•Recoverability and/or realization of the carrying value of our intangible assets, long-lived assets, and deferred tax assets.

•Effectiveness of our risk management program.

•Contingencies and the level and results of litigation.

•Fluctuation in foreign currency exchange rates.

•Our ability to meet sustainability standards and expectations of investors, regulators, customers, and other stakeholders.

For further discussion of risks and uncertainties which could cause actual results to differ from those contained in the forward-looking statements, see Part 1, Item 1A of our annual report on Form 10-K for the year ended December 31, 2025.

All subsequent written and oral forward-looking statements attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)    

Unum Group and Subsidiaries

September 30, 2026

Note 1 - Basis of Presentation

The accompanying consolidated financial statements of Unum Group and its subsidiaries (the Company) have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. For further information, refer to the consolidated financial statements and footnotes included in our annual report on Form 10-K for the year ended December 31, 2025.

In our opinion, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Interim results are not necessarily indicative of full-year performance.

Note 2 - Accounting Developments

Accounting Updates Adopted in 2025:

ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures

The amendments in this update required greater disaggregation of income tax disclosures related to the income tax rate reconciliation and income taxes paid. Specifically, the guidance required additional information that met a quantitative threshold in specified categories with respect to the reconciliation of the effective tax rate to the statutory tax rate for federal, state, and foreign income taxes. The specified categories were the following: state and local income taxes, foreign tax effects, effect of cross-border tax laws, enactment of new tax laws, nontaxable or nondeductible items, tax credits, changes in valuation allowances, and changes in unrecognized tax benefits. The quantitative threshold for each category is five percent of the amount computed by multiplying income (or loss) from continuing operations before income taxes by the statutory federal income tax rate. In addition, the amendments required additional information pertaining to income taxes paid, net of refunds, to be disaggregated by federal, state and foreign jurisdictions, and further disaggregated for specific jurisdictions to the extent the related amounts exceeded a quantitative threshold of five percent of total income taxes paid. The amendments also required disclosures of income (or loss) before income tax expense (or benefit) as domestic or foreign for each annual reporting period.

The amendments eliminated the historic requirement to disclose information regarding unrecognized tax benefits having a reasonable possibility of significantly increasing or decreasing in the twelve months following the reporting date, as well as the requirement to disclose the cumulative temporary differences when a deferred tax liability was not recognized due to certain exceptions under ASC 740.

The amendments in this update were applied retrospectively for the annual period ended December 31, 2025. The adoption of this update modified our disclosures, but did not have an impact on our financial position or results of operations.

Accounting Updates Outstanding:

ASU 2024-03, Disaggregation of Income Statement Expenses: Income Statement - Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses and related amendment

The amendments in this update require the disclosure of disaggregation of certain income statement expense line items. Specifically, the guidance requires the disclosure of additional information related to certain expenses, including employee compensation, depreciation and amortization, and certain other expenses included in each income statement line item. The amendments also require the disclosure of both the total amount of selling expenses and a definition of selling expenses.

We will adopt this update effective for the annual period beginning January 1, 2027, and interim periods beginning January 1, 2028. The adoption of this update is permitted on a prospective basis or a retrospective basis. The adoption of this update will expand our disclosures but will not have an impact on our financial position or results of operations.

Note 2 - Accounting Developments - Continued

ASU 2025-06, Targeted Improvements to the Accounting for Internal-Use Software: Intangibles - Goodwill and Other Internal-Use Software (Subtopic 350-40)

The amendments in this update modernize the recognition framework for the capitalization of internal-use software and remove all references to software development project stages. The guidance requires software development costs to be capitalized when both of the following criteria are met: (i) management has authorized and committed to funding the project, and (ii) it is probable that the project will be completed and the software will be used to perform its intended function. Additionally, the update aligns disclosure requirements for capitalized software costs with those under ASC 360-10, Property, Plant, and Equipment.

We will adopt this update effective for the interim and annual periods beginning January 1, 2028. The adoption of this update is permitted on a prospective, retrospective, or modified retrospective basis. We are currently evaluating the impact the adoption of this update will have on our financial position, results of operations, and disclosures.

Note 3 - Fair Value of Financial Instruments

Fair Value Measurements for Financial Instruments Carried at Fair Value

We report fixed maturity securities, which are classified as available-for-sale securities, derivative financial instruments, and unrestricted equity securities at fair value in our consolidated balance sheets. We report our investments in private equity partnerships at our share of the partnerships' net asset value (NAV) per share or its equivalent as a practical expedient for fair value.

The degree of judgment utilized in measuring the fair value of financial instruments generally correlates to the level of pricing observability. Financial instruments with readily available active quoted prices or for which fair value can be measured from actively quoted prices in active markets generally have more pricing observability and less judgment utilized in measuring fair value. An active market for a financial instrument is a market in which transactions for an asset or a similar asset occur with sufficient frequency and volume to provide pricing information on an ongoing basis. A quoted price in an active market provides the most reliable evidence of fair value and should be used to measure fair value whenever available. Conversely, financial instruments rarely traded or not quoted have less observability and are measured at fair value using valuation techniques that require more judgment. Pricing observability is generally impacted by a number of factors, including the type of financial instrument, whether the financial instrument is new to the market and not yet established, the characteristics specific to the transaction, and overall market conditions.

We classify financial instruments in accordance with a fair value hierarchy consisting of three levels based on the observability of valuation inputs:

•Level 1 - the highest category of the fair value hierarchy classification wherein inputs are unadjusted and represent quoted prices in active markets for identical assets or liabilities at the measurement date.

•Level 2 - valued using inputs (other than prices included in Level 1) that are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument's anticipated life.

•Level 3 - the lowest category of the fair value hierarchy and reflects the judgment of management regarding what market participants would use in pricing assets or liabilities at the measurement date. Financial assets and liabilities categorized as Level 3 are generally those that are valued using unobservable inputs to extrapolate an estimated fair value.

Note 3 - Fair Value of Financial Instruments - Continued

Valuation Methodologies of Financial Instruments Measured at Fair Value

Valuation techniques used for assets and liabilities accounted for at fair value are generally categorized into three types. The market approach uses prices and other relevant information from market transactions involving identical or comparable assets or liabilities. The income approach converts future amounts, such as cash flows or earnings, to a single present amount, or a discounted amount. The cost approach is based upon the amount that currently would be required to replace the service capacity of an asset, or the current replacement cost.

We use valuation techniques that are appropriate in the circumstances and for which sufficient data are available that can be obtained without undue cost and effort. In some cases, a single valuation technique will be appropriate (for example, when valuing an asset or liability using quoted prices in an active market for identical assets or liabilities). In other cases, multiple valuation techniques will be appropriate. If we use multiple valuation techniques to measure fair value, we evaluate and weigh the results, as appropriate, considering the reasonableness of the range indicated by those results. A fair value measurement is the point within that range that is most representative of fair value in the circumstances.

The selection of the valuation method(s) to apply considers the definition of an exit price and depends on the nature of the asset or liability being valued. For assets and liabilities accounted for at fair value, we generally use valuation techniques consistent with the market approach, and to a lesser extent, the income approach. We believe the market approach provides more observable data than the income approach, considering the type of investments we hold. Our fair value measurements could differ significantly based on the valuation technique and available inputs. When using a pricing service, we obtain the vendor's pricing documentation to ensure we understand their methodologies. We periodically review and approve the selection of our pricing vendors to ensure we are in agreement with their current methodologies. When markets are less active, brokers may rely more on models with inputs based on the information available only to the broker. Our internal investment management professionals, which include portfolio managers and analysts, monitor securities priced by brokers and evaluate their prices for reasonableness based on benchmarking to available primary and secondary market information. In weighing a broker quote as an input to fair value, we place less reliance on quotes that do not reflect the result of market transactions. We also consider the nature of the quote, particularly whether it is a bid or market quote. If prices in an inactive market do not reflect current prices for the same or similar assets, adjustments may be necessary to arrive at fair value. When relevant market data is unavailable, which may be the case during periods of market uncertainty, the income approach can, in suitable circumstances, provide a more appropriate fair value. During 2026, we have applied valuation approaches and techniques on a consistent basis to similar assets and liabilities and consistent with those approaches and techniques used at year end 2025.

Fixed Maturity and Equity Securities

We use observable and unobservable inputs in measuring the fair value of our fixed maturity and equity securities. For securities categorized as Level 1, fair values equal active Trade Reporting and Compliance Engine (TRACE) pricing or unadjusted market maker prices. For securities categorized as Level 2 or Level 3, inputs that may be used in valuing each class of securities at any given time period are disclosed below. Actual inputs used to determine fair values will vary for each reporting period depending on the availability of inputs which may, at times, be affected by the lack of market liquidity.

The management of our investment portfolio includes establishing pricing policy and reviewing the reasonableness of sources and inputs used in developing pricing. We review all prices that vary between multiple pricing vendors by a threshold that is outside a normal market range for the asset type.  In the event we receive a vendor's market price that does not appear reasonable based on our market analysis, we may challenge the price and request further information about the assumptions and methodologies used by the vendor to price the security. We may change the selected price based on a better data source such as an actual trade. We also review all prices that did not change from the prior month to ensure that these prices are within our expectations. The overall valuation process for determining fair values may include adjustments to valuations obtained from

our pricing sources when they do not represent a valid exit price. These adjustments may be made when, in our judgment and considering our knowledge of the financial conditions and industry in which the issuer operates, certain features of the financial instrument require that an adjustment be made to the value originally obtained from our pricing sources. These features may include the complexity of the financial instrument, the market in which the financial instrument is traded, counterparty credit risk, credit structure, concentration, or liquidity. Additionally, an adjustment to the price derived from a model typically reflects our judgment of the inputs that other participants in the market for the financial instrument being measured at fair value would consider in pricing that same financial instrument. In the event an asset is sold, we test the validity of the fair value determined by our valuation techniques by comparing the selling price to the fair value determined for the asset in the immediately preceding month end reporting period.

Certain of our investments do not have readily determinable market prices and/or observable inputs or may at times be affected by the lack of market liquidity. For these securities, we use internally prepared valuations, including valuations based on estimates of future profitability, to estimate the fair value. Additionally, we may obtain prices from independent third-party brokers to aid in establishing valuations for certain of these securities. Key assumptions used by us to determine fair value for these securities include risk free interest rates, risk premiums, performance of underlying collateral (if any), and other factors involving significant assumptions which may or may not reflect those of an active market.

The parameters and inputs used to validate a price on a security may be adjusted for assumptions about risk and current market conditions on a quarter to quarter basis, as certain features may be more significant drivers of valuation at the time of pricing. Changes to inputs in valuations are not changes to valuation methodologies; rather, the inputs are modified to reflect direct or indirect impacts on asset classes from changes in market conditions.

At September 30, 2026, approximately 24.4 percent of our fixed maturity securities were valued using active trades from TRACE pricing or market maker prices for which there was current market activity in that specific security (comparable to receiving one binding quote).  The prices obtained were not adjusted, and the assets were classified as Level 1.

The remaining 75.6 percent of our fixed maturity securities were valued based on non-binding quotes or other observable and unobservable inputs, as discussed below:

•56.0 percent of our fixed maturity securities were valued based on prices from pricing services that generally use observable inputs such as prices for securities or comparable securities in active markets in their valuation techniques. These assets were classified as Level 2. 

•17.0 percent of our fixed maturity securities were valued based on one or more non-binding broker quotes, if validated by observable market data. When only one price is available, it is used if observable inputs and analysis confirms that it is appropriate. These assets, for which we were able to validate the price using other observable market data, were classified as Level 2.

•2.6 percent of our fixed maturity securities were valued based on prices of comparable securities, internal models, or pricing services or other non-binding quotes with no other observable market data. These assets were classified as either Level 2 or Level 3, with the categorization dependent on whether there was other observable market data.

Derivatives

Fair values for derivatives other than embedded derivatives in modified coinsurance arrangements are based on market quotes or pricing models and represent the net amount of cash we would have paid or received if the contracts had been settled or closed as of the last day of the period. Credit risk related to the counterparty and the Company is considered in determining the fair values of these derivatives. However, since we have collateralization agreements in place with each counterparty which limits our exposure, any credit risk is immaterial. Therefore, we determined that no adjustments for credit risk were required as of September 30, 2026 or December 31, 2025. Fair values for our embedded derivative in a modified coinsurance arrangement are estimated using internal pricing models and represent the hypothetical value of the duration mismatch of assets and liabilities, interest rate risk, and third party credit risk embedded in the modified coinsurance arrangement. We consider transactions in inactive markets to be less representative of fair value. We use all available observable inputs when measuring fair value, but when significant unobservable inputs are used, we classify these assets or liabilities as Level 3.

Realized and unrealized investment gains and losses presented in the preceding tables represent gains and losses only for the time during which the applicable financial instruments were classified as Level 3. The transfers between levels resulted primarily from a change in observability of three inputs used to determine fair values of the securities transferred: (1) transactional data for new issuance and secondary trades, (2) broker/dealer quotes and pricing, primarily related to changes in the level of activity in the market and whether the market was considered orderly, and (3) comparable bond metrics from which to perform an analysis. For fair value measurements of financial instruments that were transferred either into or out of Level 3, we reflect the transfers using the fair value at the beginning of the period. We believe this allows for greater transparency, as all changes in fair value that arise during the reporting period of the transfer are disclosed as a component of our Level 3 reconciliation.

The table below provides quantitative information regarding the significant unobservable inputs used in Level 3 fair value measurements derived from internal models. Unobservable inputs for fixed maturity securities are weighted by the fair value of the securities. Certain securities classified as Level 3 are excluded from the table below due to limitations in our ability to obtain the underlying inputs used by external pricing sources.

(a)Represents a decision to price based on par value, cost, owner's equity, or the price of the most recent capital funding round when limited data is available

(b)Represents various actuarial assumptions required to derive the liability cash flows. Fair value of embedded derivative is most often driven by the change in the weighted average credit spread to the swap curve for the assets backing the hypothetical loan

Other than market convention, the impact of isolated decreases in unobservable inputs will result in a higher estimated fair value, whereas isolated increases in unobservable inputs will result in a lower estimated fair value. The unobservable input for market convention is not sensitive to input movements. The projected liability cash flows used in the fair value measurement of our Level 3 embedded derivative are based on expected claim payments. If claim payments increase, the projected liability cash flows will increase, resulting in a decrease in the fair value of the embedded derivative. Decreases in projected liability cash flows will result in an increase in the fair value of the embedded derivative.

Note 3 - Fair Value of Financial Instruments - Continued

Fair Value Measurements for Financial Instruments Not Carried at Fair Value

The methods and assumptions used to estimate fair values of financial instruments not carried at fair value are discussed as follows:

Mortgage Loans: Fair value of newly originated, seasoned performing, or sub-performing but likely to continue cash flowing loans are calculated using a discounted cash flow analysis. Loans’ cash flows are modeled and appropriately discounted by a rate based on current yields and credit spreads. For sub and non-performing loans where there is some probability the loan will not continue to pay, a price based approach would be used to estimate the loan’s value in the open market utilizing current transaction information from similar loans.

Policy Loans: Fair values for policy loans, net of reinsurance ceded, are estimated using discounted cash flow analyses and interest rates currently being offered to policyholders with similar policies. Carrying amounts for ceded policy loans, which equal $3,216.4 million and $3,353.8 million as of September 30, 2026 and December 31, 2025, respectively, approximate fair value and are reported on a gross basis in our consolidated balance sheets. A change in interest rates for ceded policy loans will not impact our financial position because the benefits and risks are fully ceded to reinsuring counterparties.

Miscellaneous Long-term Investments: Our shares of Federal Home Loan Bank (FHLB) common stock are carried at cost, which approximates fair value.

Funding Agreements: Funding agreements included in policyholders' account balances represent cash advances used for the purpose of investing in either short-term investments, matched fixed maturity securities, or matched commercial mortgage loans. Carrying amounts approximate fair value.

Long-term Debt: Fair values for long-term debt are obtained from independent pricing services or discounted cash flow analyses based on current incremental borrowing rates for similar types of borrowing arrangements.

Other Liabilities: Funding agreements that represent cash advances used for the purpose of investing in either short-term investments, matched fixed maturity securities, or matched commercial mortgage loans. Unfunded equity commitments represent amounts that we have committed to fund investment partnerships. These commitments are legally binding, subject to the partnerships meeting specified conditions. Carrying amounts approximate fair value.

The carrying values of financial instruments such as short-term investments, cash and bank deposits, accounts and premiums receivable, accrued investment income, securities lending agreements, and short-term debt approximate fair value due to the short-term nature of the instruments. As such, these financial instruments are not included in the above chart.

Fair values for insurance contracts other than investment contracts are not required to be disclosed. However, the fair values of liabilities under all insurance contracts are taken into consideration in our overall management of interest rate risk, which seeks to minimize exposure to changing interest rates through the matching of investment maturities with amounts due under insurance contracts.

The following chart depicts an analysis of our fixed maturity security portfolio between investment-grade and below-investment-grade categories as of September 30, 2026.

					Gross Unrealized Loss
	Fair Value		Gross Unrealized Gain		Amount		Percent of Total Gross Unrealized Loss

Total Fixed Maturity Securities	$	32,994.5	$	227.9	$	3,451.6	100.0	%

The unrealized losses on investment-grade fixed maturity securities principally relate to changes in interest rates or changes in market or sector credit spreads which occurred subsequent to the acquisition of the securities. Below-investment-grade fixed maturity securities are generally more likely to develop credit concerns than investment-grade securities. At September 30, 2026, the unrealized losses in our below-investment-grade fixed maturity securities were generally due to credit spreads in certain industries or sectors and, to a lesser extent, credit concerns related to specific securities. For each specific security in an unrealized loss position, we believe that there are positive factors which mitigate credit concerns and that the securities for

which we have not recorded a credit loss will recover in value. We have the ability and intent to continue to hold these securities to recovery of amortized cost less allowance for credit losses.

As of September 30, 2026, we held 999 individual investment-grade fixed maturity securities and 87 individual below-investment-grade fixed maturity securities that were in an unrealized loss position, of which 702 investment-grade fixed maturity securities and 19 below-investment-grade fixed maturity securities had been in an unrealized loss position continuously for over one year.

In determining when a decline in fair value below amortized cost of a fixed maturity security represents a credit loss, we evaluate the following factors:

•Whether we expect to recover the entire amortized cost basis of the security

•Whether we intend to sell the security or will be required to sell the security before the recovery of its amortized cost basis

•Whether the security is current as to principal and interest payments

•The significance of the decline in value

•Current and future business prospects and trends of earnings

•The valuation of the security's underlying collateral

•Relevant industry conditions and trends relative to their historical cycles

•Market conditions

•Rating agency and governmental actions

•Bid and offering prices and the level of trading activity

•Adverse changes in estimated cash flows for securitized investments

•Changes in fair value subsequent to the balance sheet date

•Any other key measures for the related security

While determining whether a credit loss exists is a judgmental area, we utilize a formal, well-defined, and disciplined process to monitor and evaluate our fixed income investment portfolio, supported by issuer specific research and documentation as of the end of each period. The process results in a thorough evaluation of investments and the recording of credit losses on a timely basis for investments determined to have a credit loss. We calculate the allowance for credit losses of fixed maturity securities based on the present value of our best estimate of cash flows expected to be collected, discounted using the effective interest rate implicit in the security at the date of acquisition. When estimating future cash flows, we analyze the strength of the issuer’s balance sheet, its debt obligations and near-term funding arrangements, cash flow and liquidity, the profitability of its core businesses, the availability of marketable assets which could be sold to increase liquidity, its industry fundamentals and regulatory environment, and its access to capital markets.

At September 30, 2026, we had commitments of $182.6 million to fund private placement fixed maturity securities, the amount of which may or may not be funded. 

Variable Interest Entities

We invest in variable interests issued by variable interest entities. These investments, which are passive in nature, include minority ownership interests in private equity partnerships and special purpose entities. Our maximum exposure to loss is limited to the carrying value of these investments in private equity partnerships and special purpose entities. For those variable interests that are not consolidated in our financial statements, we are not the primary beneficiary because we have neither the power to direct the activities that are most significant to economic performance nor the responsibility to absorb a majority of the expected losses. The determination of whether we are the primary beneficiary is performed at the time of our initial investment and at the date of each subsequent reporting period.

As of September 30, 2026, the carrying amount of our variable interest entity investments not consolidated in our financial statements, which are primarily private equity partnerships, totaled $1,448.1 million. At December 31, 2025, the carrying amount of our variable interest entity investments not consolidated in our financial statements, which are primarily private equity partnerships, totaled $1,456.3 million. These variable interest entity investments are reported as other long-term investments in our consolidated balance sheets.

Mortgage Loans

Our mortgage loan portfolio is well diversified by both geographic region and property type to reduce risk of concentration. All of our mortgage loans are collateralized by commercial real estate. When issuing a new loan, our general policy is not to exceed a loan-to-value ratio, or the ratio of the loan balance to the estimated fair value of the underlying collateral, of 75 percent. We update the loan-to-value ratios based on internal valuation of the collateral at least every three years for each loan, and properties undergo a general inspection at least every two years. At loan origination, we compare the property net

operating income with debt service payments and generally target loans with a debt service coverage ratio above 1.2 times. We update our debt service coverage ratios annually.

We carry our mortgage loans at amortized cost less an allowance for expected credit losses. The amortized cost of our mortgage loans was $2,069.6 million and $2,125.4 million at September 30, 2026 and December 31, 2025, respectively. The allowance for expected credit losses was $16.4 million and $15.9 million at September 30, 2026 and December 31, 2025, respectively. Interest income is accrued on the principal amount of the loan based on the loan's contractual interest rate. We report accrued interest income for our mortgage loans as accrued investment income on our consolidated balance sheets, and the amount of the accrued income was $6.7 million at both September 30, 2026 and December 31, 2025.

Events or developments, such as economic conditions that impact the ability of the borrowers to ensure occupancy of the property, may have a negative effect on our mortgage loan portfolio, particularly to the extent that our portfolio is concentrated in an affected region or property type. An increase in vacancies increases the probability of default, which would negatively affect our expected losses in our mortgage loan portfolio.

We evaluate each of our mortgage loans individually for impairment and assign an internal quality rating based on a comprehensive rating system used to evaluate the risk of the loan. The factors we use to derive our internal quality ratings may include the following:

•Loan-to-value ratio based on internal valuation of the property

•Debt service coverage ratio based on current operating income

•Property location, including regional economics, trends, and demographics

•Age, condition, and construction quality of property

•Current and historical occupancy of property

•Lease terms relative to market

•Tenant size and financial strength

•Borrower's financial strength

•Borrower's equity in collateral

•Additional collateral, if any

Although all available and applicable factors are considered in our analysis, loan-to-value and debt service coverage ratios are the most critical factors in determining whether we will initially issue the loan and also in assigning values and determining impairment. We assign an overall rating to each loan using an internal rating scale of AA (highest quality) to B (lowest quality). We review and adjust, as needed, our internal quality ratings on an annual basis. This review process is performed more frequently for mortgage loans deemed to have a higher risk of delinquency.

We estimate an allowance for credit losses that we expect to incur over the life of our mortgage loans using a probability of default method. For each loan, we estimate the probability that the loan will default before its maturity (probability of default) and the amount of the loss if the loan defaults (loss given default). These two factors result in an expected loss percentage that is applied to the amortized cost of each loan to determine the expected credit loss. As we are the original underwriter of the mortgage loans, the amortized cost generally equals the principal amount of the loan. We measure losses on defaults of our mortgage loans as the excess amortized cost of the mortgage loan over the fair value of the underlying collateral in the event that we foreclose on the loan or over the expected future cash flows of the loan if we retain the mortgage loan until payoff. We do not purchase mortgage loans with existing credit impairments.

In estimating the probability of default, we consider historical experience, current market conditions, and reasonable and supportable forecasts about the future market conditions. We utilize our historical loan experience in combination with a large third-party industry database for a period of time that aligns with the average life of our loans based on the maturity dates of the loans and prepayment experience. Our model utilizes an industry database of the historical loss experience based on our actual portfolio characteristics such as loan-to-value, debt service coverage, collateral type, geography, and late payment history. In addition, because we actively manage our portfolio, we may extend the term of a loan in certain situations and will accordingly extend the maturity date in the estimate of probability of default. In estimating the loss given default, we primarily consider the type and value of collateral and secondarily the expected liquidation costs and time to recovery.

The primary market factors that we consider in our forecast of future market conditions are gross domestic product, unemployment rates, interest rates, inflation, commercial real estate values, household formation, and retail sales. We also forecast certain loan specific factors such as growth in the fair value and net operating income of collateral by property type. We include our estimate of these factors over a two-year period and for the remainder of the loans’ estimated lives, adjusted for estimated prepayments. Past the two-year forecast period, we revert to the historical assumptions ratably by the end of the fifth year of the loan after which we utilize only historical assumptions.

We utilize various scenarios to estimate our allowance for expected losses ranging from a base case scenario that reflects normal market conditions to a severe case scenario that reflects adverse market conditions. We will adjust our allowance each period to utilize the scenario or weighting of the scenarios that best reflects our view of current market conditions.

During the nine months ended September 30, 2026, no commercial mortgage loans were modified for borrowers experiencing financial difficulties. During the nine months ended September 30, 2025, we granted an other-than-insignificant payment delay for a commercial mortgage loan with an amortized cost of $14.2 million, which deferred the principal payment for 24 months. This modification represents less than one percent of the commercial mortgage loan portfolio balance. For the three and nine months ended September 30, 2026 and 2025, all commercial loans which were previously modified for borrowers experiencing financial difficulties were current.

As of September 30, 2026 and December 31, 2025, we held no specifically identified impaired mortgage loans. As of September 30, 2025 we held one specifically identified impaired mortgage loan with a carrying value of $8.4 million that was past due regarding principal and/or interest payments. During the three months ended September 30, 2025, it was determined that this loan required further impairment, resulting in a $0.8 million write-off. During the fourth quarter of 2025, the property securing the loan was sold, resulting in a loss on disposal of $1.1 million. No interest income was recognized on this loan following impairment. There were no commercial mortgage loans past due as to principal and/or interest payments as of September 30, 2026 and December 31, 2025.

As of September 30, 2026 and December 31, 2025, we had no commercial mortgage loan foreclosures.

At September 30, 2026, we had $11.1 million of commitments to fund commercial mortgage loans. We estimate expected credit losses for loans that have not been funded but we are committed to fund at the end of each period using consistent methodology as our current expected credit losses for our funded mortgage loans. At September 30, 2026 and December 31, 2025, we had a nominal amount and no amount, respectively, of expected credit losses related to unfunded commitments on our consolidated balance sheets.

Investment Real Estate

Our investment real estate held for the production of income balance was $60.8 million and $41.7 million at September 30, 2026 and December 31, 2025, respectively, and the associated accumulated depreciation was $204.3 million and $130.1 million at September 30, 2026 and December 31, 2025, respectively. We monitor and assess our real estate investments for impairment when facts and circumstances indicate that the real estate may be impaired.

Our held for sale real estate balance was $5.0 million and $41.9 million at September 30, 2026 and December 31, 2025 and the associated accumulated depreciation was $4.7 million and $57.5 million at September 30, 2026 and December 31, 2025, respectively. The estimated fair values less costs to sell are above the carrying values of the properties and we expect to close the sales of the properties within the next twelve months.

Transfers of Financial Assets

To manage our cash position more efficiently, we may enter into repurchase agreements with unaffiliated financial institutions. We generally use repurchase agreements as a means to finance the purchase of invested assets or for short-term general business purposes until projected cash flows become available from our operations or existing investments. Our repurchase agreements are typically outstanding for less than 30 days. We post collateral through our repurchase agreement transactions whereby the counterparty commits to purchase securities with the agreement to resell them to us at a later, specified date. The fair value of collateral posted is generally 102 percent of the cash received.

Our investment policy also permits us to lend fixed maturity securities to unaffiliated financial institutions in short-term securities lending agreements. These agreements increase our investment income with minimal risk. Our securities lending policy requires that a minimum of 102 percent of the fair value of the securities loaned be maintained as collateral. We may receive cash and/or securities as collateral under these agreements. Cash received as collateral is typically reinvested in short-term investments. If securities are received as collateral, we are not permitted to sell or re-post them.

Certain of our U.S. insurance subsidiaries are members of regional FHLBs. As members of the FHLBs, our insurance subsidiaries have the ability to borrow on a collateralized basis from the FHLBs. Each member is required to hold a certain minimum amount of FHLB common stock as a condition of membership and additional amounts based on the amount of the borrowings. Advances received from the FHLB are primarily used for the purchase of short-term investments, matched fixed maturity securities, or matched commercial mortgage loans. The carrying value of common stock owned at September 30, 2026 and December 31, 2025 was $50.4 million and $40.7 million, respectively.

Funding Agreement-Backed Loan Program

During February 2026, we established a funding agreement-backed loan (FABL) program, pursuant to which a special purpose unaffiliated Delaware statutory trust (the FABL trust) may borrow funds under a six-month delayed draw term loan facility (the facility) and deposit the proceeds with Colonial Life & Accident Insurance Company (Colonial Life & Accident), a wholly owned insurance subsidiary, pursuant to funding agreements issued by Colonial Life & Accident to the FABL trust. Colonial Life & Accident does not hold any variable interests in the FABL trust. The deposits received by Colonial Life & Accident under the funding agreements will be used for spread lending purposes. The facility permits borrowings by the FABL trust in two tranches, in an aggregate principal amount of up to $500.0 million, with scheduled maturities on the third and fifth anniversaries, respectively, of the date that is six months after the date of the applicable credit agreement. The funding agreements issued by Colonial Life & Accident will have matching interest, maturity and payment terms to the applicable borrowings by the FABL trust. The funding agreements may be collateralized by eligible securities, including agency securities, corporate bonds, municipal bonds, and U.S. Treasury securities. As of September 30, 2026, the funding agreements had been fully collateralized and Colonial Life & Accident had principal outstanding of $500.0 million which are included in policyholders' account balances on the consolidated balance sheets.

Offsetting of Financial Instruments

We enter into master netting agreements with each of our derivative's counterparties. These agreements provide for conditional rights of set-off upon the occurrence of an early termination event. An early termination event is considered a default, and it allows the non-defaulting party to offset its contracts in a loss position against any gain positions or payments due to the defaulting party. Under our agreements, default type events are defined as failure to pay or deliver as contractually agreed, misrepresentation, bankruptcy, or merger without assumption. See Note 5 for further discussion of collateral related to our derivative contracts.

We have securities lending agreements with unaffiliated financial institutions that post collateral to us in return for the use of our fixed maturity securities. A right of set-off exists that allows us to keep and apply collateral received in the event of default by the counterparty. Default within a securities lending agreement would typically occur if the counterparty failed to return the securities borrowed from us as contractually agreed. In addition, if we default by not returning collateral received, the counterparty has a right of set-off against our securities or any other amounts due to us.

1During the three and nine months ended September 30, 2026 we recognized $754.4 million of realized losses based on the intent to dispose of fixed maturity securities with a fair value of $4,232.3 million related to the 2026 reinsurance transaction with Fortitude Reinsurance Company Ltd. (Fortitude Re). Our investment gains and losses on fixed maturity securities for the third quarter and first nine months of 2025 were driven primarily by the Closed Block long-term care and Unum US individual disability reinsurance transaction (2025 Fortitude Re reinsurance transaction) which resulted in a net gain of $137.6 million in the third quarter of 2025 and a net loss of $46.8 million in the first nine months of 2025. We also realized a $19.1 million loss on sales of fixed maturity securities related to the funding of an extraordinary dividend from a wholly owned insurance subsidiary to Unum Group in the first nine months of 2025.

Note 5 - Derivative Financial Instruments

Purpose of Derivatives

We are exposed to certain risks relating to our ongoing business operations and anticipated reinsurance transactions. The primary risks managed by using derivative instruments are interest rate risk, risk related to matching duration for our assets and liabilities, foreign currency risk, credit risk, and equity risk. Historically, we have utilized current and forward interest rate swaps, current and forward currency swaps, forward benchmark interest rate locks, currency forward contracts, forward contracts on specific fixed income securities, and total return swaps. Transactions hedging interest rate risk are primarily associated with our individual and group long-term care and individual and group disability products. All other product portfolios are periodically reviewed to determine if hedging strategies would be appropriate for risk management purposes. We do not use derivative financial instruments for speculative purposes.

Derivatives designated as cash flow hedges and used to reduce our exposure to interest rate and duration risk are as follows:

•Interest rate swaps were used to hedge interest rate risks and to improve the matching of assets and liabilities. An interest rate swap is an agreement in which we agree with other parties to exchange, at specified intervals, the difference between fixed rate and variable rate interest amounts. We used interest rate swaps to hedge the anticipated purchase of fixed maturity securities thereby protecting us from the potential adverse impact of declining interest rates

on the associated policy reserves. We also used interest rate swaps to hedge the potential adverse impact of rising interest rates in anticipation of issuing fixed rate long-term debt.

•Forward benchmark interest rate locks are used to minimize interest rate risk associated with the anticipated purchase or associated future coupons of fixed maturity securities or the anticipated issuance of fixed rate long-term debt. A forward benchmark interest rate lock is a derivative contract without an initial investment where we and the counterparty agree to purchase or sell a specific benchmark interest rate fixed maturity bond at a future date at a predetermined price or yield.

Derivatives designated as either cash flow or fair value hedges and used to reduce our exposure to foreign currency risk are as follows:

•Foreign currency interest rate swaps are used to hedge the currency risk of certain foreign currency-denominated fixed maturity securities owned for portfolio diversification. Under these swap agreements, we agree to pay, at specified intervals, fixed rate foreign currency-denominated principal and interest payments in exchange for fixed rate payments in the functional currency of the operating segment.

Derivatives not designated as hedging instruments, which are used to reduce our exposure to foreign currency risk, volatility of the underlying deferred assets in our non-qualified defined contribution plan, credit risk, interest rate risk, and duration risk are as follows:

•Foreign currency interest rate swaps previously designated as hedges were used to hedge the currency risk of certain foreign currency-denominated fixed maturity securities owned for portfolio diversification. These derivatives were effective hedges prior to novation to a new counterparty. In conjunction with the novation, these derivatives were de-designated as hedges. We agree to pay, at specified intervals, fixed rate foreign currency-denominated principal and interest payments in exchange for fixed rate payments in the functional currency of the operating segment. We hold offsetting swaps wherein we agree to pay fixed rate principal and interest payments in the functional currency of the operating segment in exchange for fixed rate foreign currency-denominated payments.

•Foreign currency forward contracts are used to minimize foreign currency risk. A foreign currency forward is a derivative without an initial investment where we and the counterparty agree to exchange a specific amount of currencies, at a specific exchange rate, on a specific date. We use these forward contracts to hedge the currency risk arising from foreign-currency denominated investments.

•Total return swaps are used to economically hedge a portion of the liability related to our non-qualified defined contribution plan. They are also used to economically hedge the interest rate and duration risk associated with a portion of the consideration payable upon closing of the 2026 Fortitude Re reinsurance transaction. In addition, we have used total return swaps to hedge the economic risk from credit spread and interest rate duration exposure related to certain cash and cash equivalent amounts. A total return swap is an agreement in which we pay a floating rate of interest and a spread to the counterparty and receive the total return on a portfolio of mutual funds and/or exchange traded funds. These swaps may be settled/reset periodically during the term of the contract or at maturity, depending on the terms of the underlying agreement.

•Forward benchmark interest rate locks are used to hedge interest rate and duration risk associated with a portion of the consideration payable upon closing of the 2026 Fortitude Re reinsurance transaction. A forward benchmark interest rate lock is a derivative contract without an initial investment where we and the counterparty agree to purchase or sell a specific benchmark interest rate fixed maturity bond at a future date at a predetermined price or yield.

•Interest rate swaps are used to economically hedge interest rate risk associated with certain floating rate liabilities. An interest rate swap is an agreement in which we agree with other parties to exchange, at specified intervals, the difference between fixed rate and variable rate interest amounts. We use these interest rate swaps to reduce the variability of cash flows associated with certain floating rate liabilities.

Derivative Risks

The basic types of risks associated with derivatives are market risk (that the value of the derivative will be adversely impacted by changes in the market, primarily changes in interest rates, exchange rates, and equity prices) and credit risk (that the counterparty will not perform according to the terms of the contract). The market risk of the derivatives should generally offset the market risk associated with the hedged financial instrument or liability. To help limit the credit exposure of the derivatives, we enter into master netting agreements with our counterparties whereby contracts in a gain position can be offset against contracts in a loss position. We also typically enter into bilateral, cross-collateralization agreements with our counterparties to help limit the credit exposure of the derivatives. These agreements require the counterparty in a loss position to submit acceptable collateral with the other counterparty in the event the net loss position meets or exceeds an agreed upon amount. Credit exposure on derivatives is limited to the value of those contracts in a net gain position, including accrued interest receivable less collateral held. At September 30, 2026, we had $2.2 million credit exposure on derivatives. At December 31, 2025, we had no credit exposure on derivatives. The table below summarizes the nature and amount of collateral received from and posted to our derivative counterparties.

	September 30, 2026		December 31, 2025
	(in millions of dollars)
Carrying Value of Collateral Received from Counterparties
Cash	$	—	$	1.6
Fixed Maturity Securities	1.0		4.2

Carrying Value of Collateral Posted to Counterparties
Cash	$	7.7	$	—
Fixed Maturity Securities	439.6		244.3
	$	447.3	$	244.3

See Note 4 for further discussion of our master netting agreements.

All of our derivative instruments contain provisions that require us to maintain specified issuer credit ratings and financial strength ratings. Should our ratings fall below these specified levels, we would be in violation of the provisions, and our derivatives counterparties could terminate our contracts and request immediate payment. The aggregate fair value of all derivative instruments with credit risk-related contingent features that were in a liability position was $421.5 million and $269.7 million at September 30, 2026 and December 31, 2025, respectively.

Cash Flow Hedges

As of September 30, 2026 and December 31, 2025, we had $109.2 million and $127.3 million, respectively, notional amount of receive fixed, pay fixed, open current and forward foreign currency interest rate swaps to hedge fixed income foreign currency-denominated securities.

As of September 30, 2026 and December 31, 2025, we had $2,311.0 million and $2,603.0 million, respectively, notional amount of forward benchmark interest rate locks to hedge the anticipated purchase of fixed maturity securities.

As of September 30, 2026, we expect to amortize approximately $(0.4) million of net deferred losses on derivative instruments during the next twelve months. This amount will be reclassified from AOCI into earnings and reported on the same income statement line item as the hedged item. The income statement line items that will be affected by this amortization are net investment income and interest and debt expense. Additional amounts that may be reclassified from AOCI into earnings to offset the earnings impact of foreign currency translation of hedged items are not estimable.

As of September 30, 2026, we are hedging the variability of future cash flows associated with forecasted transactions through the year 2053.

Fair Value Hedges

As of September 30, 2026 and December 31, 2025, we had $848.0 million and $768.6 million, respectively, notional amount of receive fixed, pay fixed, open current and forward foreign currency interest rate swaps to hedge fixed income foreign currency-denominated securities.

The following tables summarize the amortized cost, carrying amount of hedged assets, and the related cumulative basis adjustments related to our fair value hedges.

For the three and nine months ended September 30, 2026, $(16.1) million and $(23.5) million, respectively, of the derivative instruments' gain (loss) related to cross-currency basis spread and forward points was excluded from the assessment of hedge effectiveness. For the three and nine months ended September 30, 2025, $6.4 million and $31.3 million, respectively, of the derivative instruments' gain (loss) related to cross-currency basis spread and forward points was excluded from the assessment of hedge effectiveness. There were no instances wherein we discontinued fair value hedge accounting due to a hedged firm commitment no longer qualifying as a fair value hedge.

Derivatives not Designated as Hedging Instruments

As of September 30, 2026 and December 31, 2025, we held $82.9 million and $115.6 million, respectively, notional amount of receive fixed, pay fixed, foreign currency interest rate swaps. These derivatives are not designated as hedges, and as such, changes in fair value related to these derivatives are reported in earnings as a component of net investment gain or loss.

As of September 30, 2026 and December 31, 2025, we held $45.8 million and $48.9 million, respectively, notional amount of foreign currency forwards to mitigate the foreign currency risk associated with specific securities owned. These derivatives are not designated as hedges, and as such, changes in fair value related to these derivatives are reported in earnings as a component of net investment gain or loss.

As of September 30, 2026 and December 31, 2025, we held $172.5 million and $154.8 million, respectively, notional amount of total return swaps to mitigate the volatility associated with changes in the fair value of the underlying notional assets in our non-qualified defined contribution plan. This derivative is an economic hedge not designated as a hedging instrument, and changes in fair value are reported as a component of other expenses in our consolidated statements of operations.

Note 5 - Derivative Financial Instruments - Continued

As of September 30, 2026 and December 31, 2025, we held total return swap contracts with notional amounts of $549.8 million and zero, respectively, and forward benchmark interest rate lock contracts with notional amounts of $832.0 million and zero, respectively, to economically hedge risks associated with consideration payable in connection with reinsurance transactions with Fortitude Re. These derivatives are not designated as hedging instruments. Changes in fair value are reported in consolidated statements of operations in net investment gain or loss. Contract settlements, dividend payments, and financing costs are reported in net investment income. During 2025, we entered into a $700.0 million total return swap related to a reinsurance transaction with Fortitude Re that was unwound and settled for cash in the second quarter of 2025.

As of September 30, 2026, we held interest rate swap contracts with a notional amount of $205.8 million to mitigate interest rate risk associated with certain floating rate liabilities associated with our spread lending program. No such derivatives were held as of December 31, 2025. These derivatives are not designated as hedging instruments, and as such, changes in fair value related to these derivatives are reported in earnings as a component of net investment gain or loss. Net interest settlements are reported in earnings as a component of net investment income.

We have an embedded derivative in a modified coinsurance arrangement, for which we include in our net investment gains and losses a calculation intended to estimate the value of the option of our reinsurance counterparty to cancel the reinsurance contract with us. However, neither party can unilaterally terminate the reinsurance agreement except in extreme circumstances resulting from regulatory supervision, delinquency proceedings, or other direct regulatory action. Cash settlements or collateral related to this embedded derivative are not required at any time during the reinsurance contract or at termination of the reinsurance contract. There are no credit-related counterparty triggers, and any accumulated embedded derivative gain or loss reduces to zero over time as the reinsured business winds down.

Note 7 - Liability for Future Policy Benefits

Liabilities for future policy benefits represent the cost of claims that we estimate we will eventually pay to our policyholders which includes policy liabilities for claims not yet incurred and for claims that have been incurred or are estimated to have been incurred but not yet reported to us. Liabilities for future policy benefits also include the related expenses for our non interest-sensitive life and accident and health products. The liability for future policy benefits is calculated based on the present value of the estimated future policy benefits less the present value of estimated future net premiums collected. Net premiums represent the portion of the gross premium required to provide for all benefits and expenses, excluding acquisition costs or any costs that are required to be charged to expense as incurred. Insureds who have experienced an insured event and for whom future benefit payments are expected after the reporting date are considered to be on claim. For Unum US group disability, Unum US group life and accidental death and dismemberment, Unum UK group disability, and Unum UK group life policies, the tables presenting the balances and changes in the liability for future policy benefits represent only insureds on claim, as there is generally no liability for future policy benefits for insureds not on claim. Therefore, the present value of expected net premiums and expected future gross premiums (both discounted and undiscounted) for Unum US group disability, Unum US group life and accidental death and dismemberment, Unum UK group disability, and Unum UK group life products will generally be zero, as we generally do not collect premium from insureds on claim. In calculating the liability for future policy benefits, our long-duration contracts are grouped into cohorts by product type and contract issue year.

The calculation of the liability for future policy benefits involves numerous assumptions including assumptions related to discount rate, lapses, mortality, and morbidity. Cash flow assumptions are reviewed and updated, as needed, at least annually. Assumptions may be updated more frequently if necessary based on trending experience and future expectations. On a quarterly basis, cohort level cash flow measures are updated based on the emergence of actual experience.

The initial, also referred to as the original, discount rate assumptions established for each cohort are used to determine interest accretion. After policy issuance or policy renewal, the discount rate assumptions are updated quarterly and used to update the liability at each reporting date to the current discount rate. The weighted average current discount rate was 6.0 percent at September 30, 2026 compared to 5.1 percent at December 31, 2025 with the increase due primarily to an increase in U.S. Treasury rates. The weighted average current discount rate was 5.1 percent at September 30, 2025 and 5.3 percent at December 31, 2024 with the decrease due primarily to a decrease in U.S. Treasury rates.

During the third quarter of 2026, we completed our annual cash flow assumption review and updated certain assumptions used to develop the liability for future policy benefits which resulted in a net decrease to the liability. The decrease to the liability for future policy benefits was driven primarily by the impact of assumption updates in our Colonial Life segment and Unum US group disability product line, partially offset by the impact of assumption updates in the Closed Block long-term care product line and in the Unum International segment. The Colonial Life assumption updates were primarily driven by lower expectations for morbidity assumptions, increased policyholder lapse rates, and lower mortality assumptions. The Unum US group disability product line assumption updates were primarily driven by favorable social security benefit offsets and claim recovery trends, partially offset by higher claim incidence. The Closed Block long-term care assumption updates were primarily driven by higher expectations for claim incidence assumptions and lower expectations for mortality assumptions, partially offset by an increase to expected future premium rate approvals. The Unum International segment assumption updates were primarily driven by higher claim incidence assumptions for our Unum UK group disability product line.

During the third quarter of 2025, we completed our annual cash flow assumption review and updated certain assumptions used to develop the liability for future policy benefits which resulted in a net increase to the liability. The increase to the liability for future policy benefits was driven primarily by the impact of assumption updates in our Closed Block long-term care product line, partially offset by the impact of assumption updates in the Unum US group disability product line and our Unum US individual disability product line. The Closed Block long-term care assumption updates were primarily driven by the removal of morbidity and mortality improvement assumptions. Also contributing were higher expectations for claim incidence assumptions, and the removal of future assumptions related to new enrollments on existing group cases, partially offset by an increase to expected future premium rate approvals and higher expectations for claim terminations. The Unum US group disability product line assumption updates were primarily related to claim resolution assumptions driven by favorable claim recovery trends and higher mortality expectations, while the Unum US individual disability product line assumption updates were primarily driven by favorable claim incidence and recovery trends.

Note 7 - Liability for Future Policy Benefits - Continued

Actual variance from expected experience during the first nine months of 2026 was due primarily to the Closed Block long-term care and Unum US group life and accidental death and dismemberment product lines. The variance in the Closed Block long-term care product line was primarily due to higher group long-term care policy terminations and related port activity, higher than expected claim incidence, and lower than expected claim terminations. The variance in the Unum US group life and accidental death and dismemberment product line was driven primarily by lower than expected claim incidence.

Actual variance from expected experience during the first nine months of 2025 was due primarily to the Closed Block long-term care, Unum US group disability, Unum US group life and accidental death and dismemberment, and Closed Block all other product lines. The variance in the Closed Block long-term care product line was primarily due to higher than expected claim incidence and mortality experience. The variance in the Unum US group disability and group life and accidental death and dismemberment product lines was primarily due to higher than expected claim resolutions driven by recoveries. Also impacting the variance in the Unum US group life and accidental death and dismemberment product line was lower than expected claim incidence. The variance in the Closed Block all other product line was driven primarily by higher than expected mortality experience driven by our individual disability product.

For the nine months ended September 30, 2026 and 2025, there were certain cohorts within the Closed Block segment, related to our long-term care product line, and within the Colonial Life segment, related to our cancer and critical illness product line for which net premiums exceed gross premiums. The cohorts for which net premiums exceeded the gross premiums within the Closed Block segment resulted in a $121.6 million reduction to income before income tax for the nine months ended September 30, 2026 and resulted in a $425.6 million reduction to income before income tax for the nine months ended September 30, 2025. There were also certain cohorts within the Colonial Life segment for which net premiums exceeded gross premiums which had an immaterial impact to income before income tax for the nine months ended September 30, 2026. The cohorts for which net premiums exceeded the gross premiums within the Colonial Life segment for the nine months ended September 30, 2025 resulted in a $10.9 million reduction to income before income tax. The impact to income for capped cohorts includes the impact of assumption updates. There were no other product lines with cohorts for which net premiums exceeded gross premiums for the nine months ended September 30, 2026 or 2025.

Note 10 - Segment Information - Continued

We measure and analyze our segment performance on the basis of "segment adjusted operating revenue" and "segment adjusted operating income" or "segment adjusted operating loss", which differ from total revenue and income before income tax as presented in our consolidated statements of operations due to the exclusion of investment gains and losses and certain other items. The excluded items impacting the periods presented herein are specified in the reconciliations below. We believe segment adjusted operating revenue and segment adjusted operating income or loss are better performance measures and better indicators of the revenue and profitability and underlying trends in our business. These performance measures are in accordance with GAAP guidance for segment reporting, but they should not be viewed as a substitute for total revenue, income before income tax, or net income.

Investment gains or losses primarily include realized investment gains or losses, expected investment credit losses, impairment losses, and gains or losses on derivatives. Investment gains or losses depend on market conditions and do not necessarily relate to decisions regarding the underlying business of our segments. Our investment focus is on investment income to support our insurance liabilities as opposed to the generation of investment gains or losses. Although we may experience investment gains or losses which will affect future earnings levels, a long-term focus is necessary to maintain profitability over the life of the business since our underlying business is long-term in nature, and we need to earn the interest rates assumed in calculating our liabilities.

We have completed reinsurance transactions to exit significant portions of our Closed Block businesses and we are no longer accepting new enrollments on existing group long-term care policies. As a result of these actions and the continued run-off of the Closed Block business, we determined that it is no longer necessary to adjust segment adjusted operating revenue or segment adjusted operating income or loss to exclude the amortization of the deferred gain on reinsurance and it is no longer necessary to adjust segment adjusted operating income or loss to exclude the amortization of the cost of reinsurance, the amortization of the deferred gain on reinsurance or the impact of non-contemporaneous reinsurance, because the majority of these items are included in Closed Block segment results. Prior period financial information has been adjusted to conform to this updated presentation.

We may at other times exclude certain other items from our discussion of financial ratios and metrics in order to enhance the understanding and comparability of our operational performance and the underlying fundamentals, but this exclusion is not an indication that similar items may not recur and does not replace net income or net loss as a measure of our overall profitability.

We no longer exclude reserve assumption updates from our adjusted operating results, and prior period financial information has been adjusted to conform to this updated presentation.

Strategic Actions

In connection with our transition to an updated operating model, during the second quarter of 2026, we recognized expenses of $30.7 million. This included $18.0 million in real estate-related costs, including $16.3 million of depreciation expense associated with investment real estate which is reflected within net investment income in the consolidated statements of operations. In addition, we incurred employee-related costs of $12.7 million, with $11.2 million reflected within compensation expense in the consolidated statements of operations and we expect payments to occur through 2027. These costs were included within our Corporate segment.

Defined Benefit Pension and Other Postretirement Benefit (OPEB) Plans

We sponsor several defined benefit pension and OPEB plans for our employees, including non-qualified pension plans.

Assuming Dilution	$	(2.65)	$	0.23	$	0.43	$	3.23

We compute basic earnings per share by dividing net income by the weighted average number of common shares outstanding for the period. In computing earnings per share assuming dilution, we include potential common shares that are dilutive (those that reduce earnings per share). We use the treasury stock method to account for the effect of nonvested restricted stock units and nonvested performance share units on the computation of diluted earnings per share. Under this method, the potential common shares from nonvested restricted stock units and nonvested performance share units will each have a dilutive effect, as individually measured, when the average market price of Unum Group common stock during the period exceeds the grant price of the nonvested restricted stock units and nonvested performance share units. The outstanding nonvested restricted stock units and nonvested performance share units have grant prices ranging from $44.75 to $94.07.

Antidilutive shares of 0.4 million and 0.1 million for the three and nine months ended September 30, 2026, respectively, were not included in the computation of diluted earnings per share because the impact would be antidilutive based on then current market prices and the effects of reporting a net loss. There were 0.3 million potential common shares that were antidilutive for the three and nine months ended September 30, 2025.

Common Stock

As part of our capital deployment strategy, we may repurchase shares of Unum Group's common stock, as authorized by our board of directors. The timing and amount of repurchase activity is based on market conditions and other considerations, including the level of available cash, alternative uses for cash, and our stock price.

2Includes a de minimis amount and $0.3 million of commissions for the three and nine months ended September 30, 2026, respectively, and $0.9 million and $1.8 million of commissions for the three and nine months ended September 30, 2025. Also includes $2.0 million and $7.7 million of excise tax for the three and nine months ended September 30, 2026, respectively, and $2.4 million and $7.4 million of excise tax for the three and nine months ended September 30, 2025, respectively.

As a part of our share repurchase program, we periodically enter into accelerated share repurchase agreements. Under the terms of these agreements, we make a prepayment to a financial counterparty for which we receive an initial delivery of approximately 75 percent of the total Unum Group common stock to be delivered under the agreement. We simultaneously enter into a forward contract indexed to the price of Unum Group common stock, which subjects the transactions to a future price adjustment. Under the terms of the agreements, we are to receive, or be required to pay, a price adjustment based on the volume weighted average price of Unum Group common stock during the term of the agreement, less a discount. Any price adjustment payable to us is settled in shares of Unum Group common stock. Any price adjustment we would be required to pay may be settled in either cash or common stock at our option. In November 2024, we paid $321.0 million to a financial counterparty as a part of an accelerated share repurchase agreement. We received an initial delivery of 3.8 million shares of our common stock. The final price adjustment settlement, along with the delivery of the remaining shares, occurred in February 2025, resulting in the delivery to us of 0.7 million additional shares. As a result of the final settlement occurring subsequent to December 31, 2024, we recorded a decrease of $80.3 million to additional paid-in capital within stockholders' equity on our

Note 13 - Commitments and Contingent Liabilities

Commitments

See Notes 3 and 4 for further discussion on certain of our investment commitments.

Contingent Liabilities

We are a defendant in a number of litigation matters that have arisen in the normal course of business, including the matters discussed below. Further, state insurance regulatory authorities and other federal and state authorities regularly make inquiries and conduct investigations concerning our compliance with applicable insurance and other laws and regulations. Given the complexity and scope of our litigation and regulatory matters, it is not possible to predict the ultimate outcome of all pending investigations or legal proceedings or provide reasonable estimates of potential losses, except if noted in connection with specific matters.

In some of these matters, no specified amount is sought. In others, very large or indeterminate amounts, including punitive and treble damages, are asserted. There is a wide variation of pleading practice permitted in the United States courts with respect to requests for monetary damages, including some courts in which no specified amount is required and others which allow the plaintiff to state only that the amount sought is sufficient to invoke the jurisdiction of that court. Further, some jurisdictions permit plaintiffs to allege damages well in excess of reasonably possible verdicts. Based on our extensive experience and that of others in the industry with respect to litigating or resolving claims through settlement over an extended period of time, we believe that the monetary damages asserted in a lawsuit or claim bear little relation to the merits of the case, or the likely disposition value. Therefore, the specific monetary relief sought is not stated.

Unless indicated otherwise, reserves have not been established for litigation and contingencies. An estimated loss is accrued when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated.

Claim Handling Matters

We and our insurance subsidiaries, in the ordinary course of our business, are engaged in claim litigation where disputes arise as a result of a denial or termination of benefits. Most typically these lawsuits are filed on behalf of a single claimant or policyholder, and in some of these individual actions punitive damages are sought, such as claims alleging bad faith in the handling of insurance claims. For our general claim litigation, we maintain reserves based on experience to satisfy judgments and settlements in the normal course. We expect that the ultimate liability, if any, with respect to general claim litigation, after consideration of the reserves maintained, will not be material to our consolidated financial condition. Nevertheless, given the inherent unpredictability of litigation, it is possible that an adverse outcome in certain claim litigation involving punitive damages could, from time to time, have a material adverse effect on our consolidated results of operations in a period, depending on the results of operations for the particular period.

From time to time class action allegations are pursued where the claimant or policyholder purports to represent a larger number of individuals who are similarly situated. Since each insurance claim is evaluated based on its own merits, there is rarely a single act or series of actions which can properly be addressed by a class action. Nevertheless, we monitor these cases closely and defend ourselves appropriately where these allegations are made.

Note 14 - Debt and Other

Credit Facilities

In November 2026, Provident Life and Accident Insurance Company (Provident), one of our traditional U.S. life insurance subsidiaries, entered into a five-year senior standby letter of credit facility to support potential funding obligations under the experience volatility cover related to the 2026 Fortitude Re reinsurance transaction with an initial commitment of $139.1 million, and annual increases up to a maximum of $172.4 million. The facility has an initial maturity date in November 2031 and is automatically extended annually for an additional twelve-month period, unless terminated. If the letter of credit is drawn, reimbursement would have interest based on the prime rate. As of the date of this filing, a letter of credit totaling $139.1 million had been issued.

In July 2026, we terminated our five-year, £75.0 million senior unsecured standby letter of credit facility, which was originally set to expire in December 2028. Also, our additional five-year, £75.0 million senior unsecured standby letter of credit facility expired, as scheduled, in July 2026. There were no borrowed amounts outstanding at the time of termination or expiration of these facilities.

Also in July 2026, we entered into a new five-year, £75.0 million senior standby letter of credit facility pursuant to which a £75.0 million letter of credit was issued in favor of Unum Limited (as beneficiary), our U.K. insurance subsidiary, and is available for borrowings up to £75.0 million until its scheduled expiration in July 2031. The credit facility provides for borrowings at an interest rate based on the Sterling Overnight Index Average rate. The credit facility may be collateralized by cash and eligible securities, including asset-backed securities, agency securities, corporate bonds and U.S. Treasury securities. As of September 30, 2026, the credit facility has not been collateralized. As of September 30, 2026, there were no borrowed amounts outstanding under the credit facility.

In April 2026, we entered into a senior letter of credit facility pursuant to which a £50.0 million letter of credit was issued in favor of Unum Limited (as beneficiary). The facility provides for drawings up to £50.0 million until its scheduled expiration five years after issuance of the letter of credit and no later than July 2031. The credit facility provides for borrowings at an interest rate based on the Sterling Overnight Index Average Rate. The credit facility may be collateralized by cash and eligible securities, including U.S. Treasury securities. As of September 30, 2026, the credit facility was fully collateralized. As of September 30, 2026, there were no borrowed amounts outstanding under the credit facility.

In April 2025, we and certain of our traditional U.S. life insurance subsidiaries, Unum Life Insurance Company of America (Unum America), Provident, and Colonial Life & Accident Insurance Company, amended and restated the terms of our existing credit agreement providing for a five-year $500.0 million senior unsecured revolving credit facility with a syndicate of lenders. The revolving credit facility, which was previously set to expire in 2027, was extended through April 2030. We may request that the lenders’ aggregate commitments of $500.0 million under the facility be increased by up to an additional $200.0 million. Other of our domestic wholly-owned subsidiaries are permitted to join the credit facility as borrowers, subject to certain conditions. Any obligation of a subsidiary under the credit facility is subject to an unconditional guarantee by Unum Group. At September 30, 2026, there were no borrowed amounts outstanding under the revolving credit facility and letters of credit totaling $1.3 million had been issued.

Borrowings under the credit facilities are subject to financial covenants, negative covenants, and events of default that are customary. The credit facilities include financial covenants based on our leverage ratio and consolidated net worth as well as covenants that limit subsidiary indebtedness and require minimum capital levels.

Junior Subordinated Debt Securities

During the first quarter of 2026, we purchased and retired $7.7 million aggregate principal amount of our 6.250% junior subordinated debt securities issued in 2018 and due 2058.

Allowance for Expected Credit Losses on Premiums Receivable

At September 30, 2026, June 30, 2026, and December 31, 2025, the allowance for expected credit losses on premiums receivable was $26.7 million, $26.9 million, and $26.1 million, respectively, on gross premiums receivable of $737.6 million, $746.7 million, and $579.5 million, respectively. The allowance for expected credit losses was generally consistent during these periods.

At September 30, 2025, June 30, 2025, and December 31, 2024, the allowance for expected credit losses on premiums receivable was $28.0 million, $27.6 million, and $26.8 million, respectively, on gross premiums receivable of $598.9 million, $691.7 million, and $584.1 million, respectively. The allowance for expected credit losses was generally consistent at September 30, 2025 compared to June 30, 2025. The increase in the allowance of $1.2 million during the nine months ended September 30, 2025 was driven by an increase in the age of premium receivable and an increase in gross premiums receivable.

Income Tax

During the third quarter of 2026, we recognized a tax benefit of $188.2 million from the release of unrecognized tax benefits related to a policyholder reserves position taken on our 2017 return following the completion of an Internal Revenue Service exam. The benefit reflects the release of the related unrecognized tax benefit liability of $112.9 million and accrued interest of $75.3 million.

During the third quarter of 2026, we established a valuation allowance that increased income tax expense by $176.2 million related to our deferred tax assets on capital losses, reflecting a change in our assessment of the realizability of these deferred tax assets. Based on expected capital losses associated with the 2026 Fortitude Re reinsurance transaction, we believe it is more likely than not that we will not be able to realize the benefit of these capital losses against future capital gains within the statutory carryforward period.

2026 Closed Block Long-Term Care Reinsurance Transaction

In July 2026, Unum America entered into a master transaction agreement with Fortitude Reinsurance Company Ltd. (Fortitude Re) which resulted in the execution of a coinsurance agreement in November 2026.

This reinsurance agreement reinsures a portion of our Closed Block individual long-term care policies on a coinsurance basis to Fortitude Re effective April 2026. The reinsurance agreement represents approximately 28 percent of total Closed Block long-term care future policy benefits as of March 31, 2026. Upon closing the transaction in November 2026, we transferred fixed maturity securities and cash with a fair value of $5,500.7 million. A final settlement is expected prior to the end of the first quarter of 2027. Fortitude Re intends to retrocede biometric risk on the reinsured block to a highly rated global reinsurer (the Retrocessionaire).

Additionally, at the closing of the transaction, Provident entered into an agreement with the Retrocessionaire whereby Provident provides an experience volatility cover for the difference between actual and expected claim experience, subject to a maximum payment of $125.0 million (in net present value terms). Payment obligations will be settled every five years and are secured by a trust account to be funded at all times with the remaining possible payment by Provident. Provident provided the experience volatility cover in exchange for a payment from the Retrocessionaire of $5.0 million at the closing of the reinsurance transaction. The experience volatility cover is accounted for under the deposit method.

Immediately prior to entering into the reinsurance agreement with Fortitude Re, Unum America recaptured the Closed Block individual long-term care business from Fairwind Insurance Company (Fairwind), an affiliated captive reinsurer.

2025 Closed Block Long-Term Care and Unum US Individual Disability Reinsurance Transaction

In February 2025, Unum America entered into a master transaction agreement with Fortitude Re which resulted in the execution of a coinsurance agreement during July 2025. This reinsurance agreement reinsures a portion of our Closed Block long-term care business and a portion of our Unum US individual disability business on a coinsurance basis to Fortitude Re effective January 2025.

Note 14 - Debt and Other - Continued

Upon closing the transaction in July 2025, we transferred to Fortitude Re $953.5 million of cash as well as fixed maturity securities with a fair value totaling $3,230.1 million and accrued investment income of $47.1 million. After consideration of the final settlement, the final ceding commission related to this transaction was $442.3 million.

As a result of this reinsurance agreement, we recognized the following:

•Net realized investment loss totaling $46.8 million during the year ended December 31, 2025.

•Reinsurance recoverable of $3,620.5 million comprised of ceded reserves of $3,315.2 million related to the Closed Block long-term care product line and $305.3 million related to the Unum US individual disability product line.

•Cost of reinsurance of $848.2 million related to the Closed Block long-term care product line and a deferred gain on reinsurance related to the Unum US individual disability product line of $145.9 million.

•Write-off of deferred acquisition costs related to the Unum US individual disability product line of $100.3 million which is included as a component of deferred gain on reinsurance.

In July 2025, immediately prior to entering into the reinsurance agreement with Fortitude Re, Unum America recaptured the aforementioned Closed Block long-term care business from Fairwind and assumed the aforementioned Unum US individual disability business from Provident.

Executive Summary

Unum Group, a Delaware general business corporation, and its insurance and non-insurance subsidiaries, which collectively with Unum Group we refer to as the Company, operate in the United States, the United Kingdom, Poland, and, to a limited extent, in certain other countries. The principal operating subsidiaries in the United States are Unum Life Insurance Company of America (Unum America), Provident Life and Accident Insurance Company (Provident), The Paul Revere Life Insurance Company, Colonial Life & Accident Insurance Company (Colonial Life & Accident), Unum Insurance Company, in the United Kingdom, Unum Limited, and in Poland, Unum Zycie TUiR S.A. (Unum Poland). We are a leading provider of financial protection benefits in the United States and the United Kingdom. Our products include disability, life, accident, critical illness, dental and vision, and other related services. We market our products primarily through the workplace.

We have three core operating segments: Unum US, Unum International, and Colonial Life. Our other operating segments are the Closed Block and Corporate segments. These segments are discussed more fully under "Segment Results" included herein in this Item 2.

The benefits we provide help the working world thrive throughout life's moments and protect people from the financial hardship of illness, injury, or loss of life. As a leading provider of employee benefits, we offer a broad portfolio of products and services through the workplace that provide support when it is needed most.

Specifically, we offer disability, life and voluntary products, on both individual and group bases, as well as provide certain fee-based services. These products and services, which can be sold stand-alone or combined with other coverages, help employers of all sizes attract and retain the talented and capable workforce they need to succeed while protecting the incomes and livelihood of their employees. We believe employer-sponsored benefits are the most effective way to provide workers with access to information and options to protect their financial stability. Working people and their families, particularly those at lower and middle incomes, are perhaps the most vulnerable in today's economy yet are often overlooked by many providers of financial products and services. For many of these workers and families, employer-sponsored benefits are the primary defense against the potentially catastrophic financial impact of death, illness, or injury.

We have established a corporate culture consistent with the social value of our products and services. We see important links between the obligations we have to all of our stakeholders, and we place a strong emphasis on operating with integrity and contributing to positive change in our communities. Accordingly, we are committed not only to meeting the needs of our customers who depend on us, but also to being accountable for our actions through sound and consistent business practices, a strong internal compliance program, a comprehensive risk management strategy, and an engaged employee workforce.

This discussion and analysis should be read in conjunction with the consolidated financial statements and notes thereto in Part I, Item 1 contained in this Form 10-Q and with the "Cautionary Statement Regarding Forward-Looking Statements" included below the Table of Contents, as well as the discussion, analysis, and consolidated financial statements and notes thereto in Part I, Items 1 and 1A, and Part II, Items 7, 7A, and 8 of our annual report on Form 10-K for the year ended December 31, 2025.

Certain prior period financial information has been adjusted to conform to current year presentation. See "Reconciliation of Non-GAAP and Other Financial Measures" contained herein in this Item 2 for more information regarding these adjustments.

Operating Performance and Capital Management

For the third quarter of 2026, we reported a net loss of $419.7 million, or $2.65 per diluted common share, compared to net income of $39.7 million, or $0.23 per diluted common share, in the third quarter of 2025. For the first nine months of 2026, we reported net income of $69.2 million, or $0.43 per diluted common share, compared to net income of $564.4 million, or $3.23 per diluted common share in the same period of 2025.

Excluding these items, after-tax adjusted operating income for the third quarter of 2026 was $349.0 million, or $2.20 per diluted common share compared to $479.4 million, or $2.81 per diluted common share, for the same period of 2025. After-tax adjusted operating income was $1,047.5 million, or $6.56 per diluted common share, in the first nine months of 2026, compared to $1,188.4 million, or $6.81 per diluted common share, in the first nine months of 2025. See "Reconciliation of Non-GAAP and Other Financial Measures" contained herein in this Item 2 for further discussion and a reconciliation of these items.

Included in after-tax adjusted operating income for the third quarter and first nine months of 2026 was the following notable item, an after-tax net reserve decrease in our core operating segments of $53.2 million in both periods, or $0.33 per diluted common share, comprised of an after-tax net reserve decrease related to assumption updates of $67.0 million, or $0.42 per diluted common share, and an after-tax reserve increase related to reserve refinements of $13.8 million, or $0.09 per diluted common share. Included in after-tax adjusted operating income for the third quarter and first nine months of 2025 was the following notable item, a net after-tax reserve decrease related to assumption updates in our core operating segments of $128.1 million in both periods, or $0.75 and $0.73 per diluted common share, respectively.

Unum US reported segment adjusted operating income of $315.3 million and $982.8 million in the third quarter and first nine months of 2026, respectively, compared to $486.8 million and $1,134.1 million in the same periods of 2025, due primarily to benefits experience, partially offset by higher premium income and net investment income. The benefit ratio for our Unum US segment was 62.0 percent and 60.9 percent in the third quarter and first nine months of 2026, respectively, compared to 51.1 percent and 57.2 percent in the same periods of 2025. Unum US sales decreased 8.5 percent in the third quarter and increased 8.6 percent in the first nine months of 2026, compared to the same periods of 2025.

Unum International reported segment adjusted operating income of $0.2 million and $55.4 million in the third quarter and first nine months of 2026, respectively, compared to $44.2 million and $124.5 million in the same periods of 2025. Our Unum UK line of business reported segment adjusted operating loss of £1.4 million in the third quarter of 2026 and reported segment adjusted operating income of £34.3 million in the first nine months of 2026, compared to income of £27.0 million and £85.9 million in the third quarter and first nine months of 2025, respectively, primarily due to benefits experience, partially offset by higher premium income. The benefit ratio for our Unum UK line of business was 91.0 percent and 82.1 percent in the third quarter and first nine months of 2026, respectively, compared to 73.4 percent and 71.9 percent in the same periods of 2025. Unum International sales, as measured in U.S. dollars, decreased 41.6 percent and 18.5 percent in the third quarter and first nine months of 2026, respectively, compared to the same periods of 2025. Unum UK sales, as measured in local currency, decreased 45.9 percent and 18.0 percent in the third quarter and first nine months of 2026, respectively, compared to the same periods of 2025.

93

Colonial Life reported segment adjusted operating income of $169.4 million and $428.6 million in the third quarter and first nine months of 2026, respectively, compared to $125.5 million and $358.6 million in the same periods of 2025, primarily due to benefits experience, higher net investment income and higher premium income. The benefit ratio for Colonial Life was 38.0 percent and 43.6 percent in the third quarter and first nine months of 2026, respectively, compared to 46.3 percent and 47.4 percent in the same periods of 2025. Colonial Life sales increased 6.4 percent and 4.7 percent in the third quarter and first nine months of 2026, respectively, compared to the same periods of 2025.

Closed Block reported segment adjusted operating loss of $135.6 million and $356.3 million in the third quarter and first nine months of 2026, respectively, compared to a loss of $682.3 million and $685.1 million in the same periods of 2025. The net premium ratio for long-term care increased to 98.1 percent at September 30, 2026 from 97.6 percent at September 30, 2025.

A rising interest rate environment could positively impact our yields on new investments, but could also increase unrealized losses in our current holdings. Alternatively, a declining interest rate environment could negatively impact our yields on new investments, but could also reduce unrealized losses in our current holdings. As of September 30, 2026, we do not hold any securities with a decline in fair value below amortized cost which we intend to sell nor any securities for which it is more likely than not that we will be required to sell before recovery in amortized cost for which an impairment loss was not recorded. During the third quarter of 2026, we recognized impairment losses totaling $754.4 million as a result of our intent to transfer certain fixed maturity securities related to the 2026 reinsurance transaction with Fortitude Reinsurance Company Ltd. (Fortitude Re). The net unrealized loss on our fixed maturity securities was $3.2 billion at September 30, 2026, compared to $1.7 billion at December 31, 2025, with the increase due primarily to an increase in U.S. Treasury rates, partially offset by investment losses recorded on certain fixed maturity securities related to the 2026 Fortitude Re reinsurance transaction. The earned book yield on our investment portfolio was 4.38 percent for the first nine months of 2026, compared to a yield of 4.35 percent for the full year ended December 31, 2025.

Additionally, a rising interest rate environment could result in reserve decreases while a declining interest rate environment could result in reserve increases, specific to our liability for future policy benefits, as the reserve discount rate assumptions used in the calculation of our liability are updated at each reporting date using a yield that is reflective of an upper-medium grade fixed income instrument, which is generally equivalent to a single-A interest rate matched to the duration of certain of our insurance liabilities. The change in discount rate assumptions on the liability for future policy benefits, net of reinsurance, due primarily to the increase in U.S. Treasury rates during the first nine months of 2026, resulted in a decrease to the liability for future policy benefits, net of reinsurance, of approximately $2.5 billion.

We believe our capital and financial positions are strong. At September 30, 2026, the risk-based capital (RBC) ratio for our traditional U.S. insurance subsidiaries, calculated on a weighted average basis using the NAIC Company Action Level formula, was approximately 485 percent, which is above our long-term expectation. We repurchased 10.0 million shares and 10.3 million shares of Unum Group common stock under our share repurchase program, during the first nine months of 2026 and 2025, respectively, at a cost of $806.5 million and $759.2 million, respectively, including commissions and excise tax. Our weighted average common shares outstanding, assuming dilution, equaled 158.6 million and 170.6 million for the third quarters of 2026 and 2025, respectively, and 159.7 million and 174.6 million for the first nine months of 2026 and 2025, respectively. As of September 30, 2026, Unum Group and our intermediate holding companies had available holding company liquidity of $1,383.4 million that was held primarily in bank deposits, commercial paper, money market funds, corporate bonds, municipal bonds and asset backed securities. See Note 12 of the "Notes to Consolidated Financial Statements" contained herein in Item 1.

2026 and 2025 Reserve Assumption Updates

During the third quarters of 2026 and 2025, we completed our annual cash flow assumption review and updated certain assumptions used to develop the liability for future policy benefits. For more information see "Critical Accounting Estimates" included herein in this Item 2.

Income Tax

During the third quarter of 2026, we recognized a tax benefit of $188.2 million from the release of unrecognized tax benefits related to a policyholder reserves position taken on our 2017 return following the completion of an Internal Revenue Service exam. The benefit reflects the release of the related unrecognized tax benefit liability of $112.9 million and accrued interest of $75.3 million.

94

During the third quarter of 2026, we established a valuation allowance that increased income tax expense by $176.2 million related to our deferred tax assets on capital losses, reflecting a change in our assessment of the realizability of these deferred tax assets. Based on expected capital losses associated with the 2026 Fortitude Re reinsurance transaction, we believe it is more likely than not that we will not be able to realize the benefit of these capital losses against future capital gains within the statutory carryforward period.

2026 Closed Block Long-Term Care Reinsurance Transaction

In July 2026, Unum America entered into a master transaction agreement with Fortitude Reinsurance Company Ltd. (Fortitude Re) which resulted in the execution of a coinsurance agreement in November 2026.

This reinsurance agreement reinsures a portion of our Closed Block individual long-term care policies on a coinsurance basis to Fortitude Re effective April 2026. The reinsurance agreement represents approximately 28 percent of total Closed Block long-term care future policy benefits as of March 31, 2026. Upon closing the transaction in November 2026, we transferred fixed maturity securities and cash with a fair value of $5,500.7 million. A final settlement is expected prior to the end of the first quarter of 2027. Fortitude Re intends to retrocede biometric risk on the reinsured block to a highly rated global reinsurer (the Retrocessionaire).

Additionally, at the closing of the transaction, Provident entered into an agreement with the Retrocessionaire whereby Provident provides an experience volatility cover for the difference between actual and expected claim experience, subject to a maximum payment of $125.0 million (in net present value terms). Payment obligations will be settled every five years and are secured by a trust account to be funded at all times with the remaining possible payment by Provident. Provident provided the experience volatility cover in exchange for a payment from the Retrocessionaire of $5.0 million at the closing of the reinsurance transaction. The experience volatility cover is accounted for under the deposit method.

Immediately prior to entering into the reinsurance agreement with Fortitude Re, Unum America recaptured the Closed Block individual long-term care business from Fairwind Insurance Company (Fairwind), an affiliated captive reinsurer.

See Notes 4, 5, and 14 in the "Notes to Consolidated Financial Statements" contained herein in Item 1 and "Investments" contained herein in this Item 2 for further information.

2025 Closed Block Long-Term Care and Unum US Individual Disability Reinsurance Transaction

In February 2025, Unum America entered into a master transaction agreement with Fortitude Re which resulted in the execution of a coinsurance agreement during July 2025. This reinsurance agreement reinsures a portion of our Closed Block long-term care business and a portion of our Unum US individual disability business on a coinsurance basis to Fortitude Re effective January 2025.

Upon closing the transaction in July 2025, we transferred to Fortitude Re $953.5 million of cash as well as fixed maturity securities with a fair value totaling $3,230.1 million and accrued investment income of $47.1 million. After consideration of the final settlement, the final ceding commission related to this transaction was $442.3 million.

As a result of this reinsurance agreement, we recognized the following:

•Net realized investment loss totaling $46.8 million during the year ended December 31, 2025.

•Reinsurance recoverable of $3,620.5 million comprised of ceded reserves of $3,315.2 million related to the Closed Block long-term care product line and $305.3 million related to the Unum US individual disability product line.

•Cost of reinsurance of $848.2 million related to the Closed Block long-term care product line and a deferred gain on reinsurance related to the Unum US individual disability product line of $145.9 million.

•Write-off of deferred acquisition costs related to the Unum US individual disability product line of $100.3 million which is included as a component of deferred gain on reinsurance.

In July 2025, immediately prior to entering into the reinsurance agreement with Fortitude Re, Unum America recaptured the aforementioned Closed Block long-term care business from Fairwind, and assumed the aforementioned Unum US individual disability business from Provident.

See Notes 4 and 14 in the "Notes to Consolidated Financial Statements" contained herein in Item 1 for further information.

Strategic Actions

In connection with our transition to an updated operating model, during the second quarter of 2026, we recognized expenses of $30.7 million. This included $18.0 million in real estate-related costs, including $16.3 million of depreciation expense associated with investment real estate which is reflected within net investment income in the consolidated statements of operations. In addition, we incurred employee-related costs of $12.7 million, with $11.2 million reflected within compensation expense in the consolidated statements of operations and we expect payments to occur through 2027. These costs were included within our Corporate segment.

Global Minimum Tax

The Organization for Economic Co-operation and Development has established model rules to ensure a minimum level of tax of 15 percent (Pillar Two) for multinational companies. Several jurisdictions, including the United Kingdom, Ireland, and Poland have adopted Pillar Two beginning on or after December 31, 2023. We have not recorded material Pillar Two taxes as of September 30, 2026. We will continue to monitor legislative developments.

Consolidated Company Outlook

We believe our strategy of providing financial protection products at the workplace puts us in a position of strength. We continue to fulfill our corporate purpose of helping the working world thrive throughout life’s moments by providing an excellent experience centered on service, expertise and empathy to people at their time of need. Our strategy remains centered on growing our core businesses, through investing and transforming our operations and technology to anticipate and respond to the changing needs of our customers, expanding into new adjacent markets through meaningful partnerships and effective deployment of our capital across our portfolio.

We expect after-tax adjusted operating income to be slightly lower in 2026 compared to 2025 due primarily to the change in reserve assumption updates. The products and services we provide deliver significant value to employers, employees and their families, and we believe this will help drive strong premium growth in 2026.

A rising interest rate environment could positively impact our yields on new investments, but could also increase unrealized losses in our current holdings. Alternatively, a declining interest rate environment could negatively impact our yields on new investments, but could also reduce unrealized losses in our current holdings. We may also continue to experience further volatility in miscellaneous investment income primarily related to changes in partnership net asset values as well as bond calls.

As part of our discipline in pricing and reserving, we continuously monitor emerging claim trends and interest rates. We will continue to take appropriate pricing actions on new business and renewals that are reflective of the current environment and may continue to utilize derivative financial instruments to manage interest rate risk.

Our business is well-diversified by geography within our markets, industry exposures and case size, and we continue to analyze and employ strategies that we believe will help us navigate the current environment. These strategies allow us to maintain financial flexibility to support the needs of our businesses, while also returning capital to our shareholders. We have strong core businesses that have a track record of generating significant free cash flow, and we will continue to invest in our operations and expand into adjacent markets where we can best leverage our expertise and capabilities to capture market growth opportunities as those opportunities emerge. We believe that consistent operating results, combined with the implementation of strategic initiatives and the effective deployment of capital, will allow us to meet our financial objectives.

As previously discussed, we entered into a reinsurance agreement with Fortitude Re to cede an additional portion of our long-term care business during November 2026.

Further discussion is included in the "Notes to Consolidated Financial Statements" contained herein in Item 1 and in "Reconciliation of Non-GAAP and Other Financial Measures," "Consolidated Operating Results," "Segment Results," "Investments," and "Liquidity and Capital Resources" contained herein in this Item 2.

Reconciliation of Non-GAAP and Other Financial Measures

We analyze our performance using non-GAAP financial measures. A non-GAAP financial measure is a numerical measure of a company's performance, financial position, or cash flows that excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with U.S. generally accepted accounting principles (GAAP). The non-GAAP financial measure of "after-tax adjusted operating income" differs from net income as presented in our consolidated statements of operations prepared in accordance with GAAP due to the exclusion of investment gains or losses, Closed Block segment after-tax adjusted operating income or loss, and certain other items. The excluded items impacting the periods presented herein are specified in the reconciliations below. We believe after-tax adjusted operating income is a better performance measure and better indicator of the profitability and underlying trends in our business.

Investment gains or losses primarily include realized investment gains or losses, expected investment credit losses, impairment losses, and gains or losses on derivatives. Investment gains or losses depend on market conditions and do not necessarily relate to decisions regarding the underlying business of our segments. Our investment focus is on investment income to support our insurance liabilities as opposed to the generation of investment gains or losses. Although we may experience investment gains or losses which will affect future earnings levels, a long-term focus is necessary to maintain profitability over the life of the business since our underlying business is long-term in nature, and we need to earn the interest rates assumed in calculating our liabilities.

We have completed reinsurance transactions to exit significant portions of our Closed Block businesses and we are no longer accepting new enrollments on existing group long-term care policies. As a result of these actions and the continued run-off of the Closed Block business, Closed Block segment earnings are less relevant to our financial results and as such, we exclude the results of the Closed Block segment from after-tax adjusted operating income. As part of this update, we also determined that it is no longer necessary to adjust after-tax adjusted operating income to exclude the amortization of the cost of reinsurance, the amortization of the deferred gain on reinsurance, and the impact of non-contemporaneous reinsurance, because the majority of these items are included in Closed Block segment results. Prior period financial information has been adjusted to conform to this updated presentation.

We may at other times exclude certain other items from our discussion of financial ratios and metrics in order to enhance the understanding and comparability of our operational performance and the underlying fundamentals, but this exclusion is not an indication that similar items may not recur and does not replace net income or net loss as a measure of our overall profitability.

We no longer exclude reserve assumption updates from our adjusted operating results, and prior period financial information has been adjusted to conform to this updated presentation.

See "Investments" contained herein in Item 2 and Notes 4, 10, and 14 of the "Notes to Consolidated Financial Statements" contained herein in Item 1 for further discussion regarding the items specified in the reconciliation below.

Critical Accounting Estimates

We prepare our financial statements in accordance with GAAP. The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect amounts reported in our financial statements and accompanying notes. Estimates and assumptions could change in the future as more information becomes known, which could impact the amounts reported and disclosed in our financial statements.

The accounting estimates deemed to be most critical to our financial position and results of operations are those related to the liability for future policy benefits, valuation of investments, income taxes, and contingent liabilities. The critical accounting estimates for which there were significant changes during the nine months ended September 30, 2026, are included below. For additional information on the accounting estimates for which there was not a significant change during the nine months ended September 30, 2026, refer to our significant accounting policies in Note 1 of the "Notes to Consolidated Financial Statements" in Part II, Item 8, and "Critical Accounting Estimates" in Part II, Item 7 of our annual report on Form 10-K for the year ended December 31, 2025.

Liability for Future Policy Benefits

2026 and 2025 Cash Flow Assumption Review

During the third quarters of 2026 and 2025, we completed our annual cash flow assumption review which resulted in the following impacts to net income as a result of updating certain assumptions related to the liability for future policy benefits:

	Three and Nine Months Ended September 30
	(in millions of dollars)
	2026		2025
Unum US
Group Disability	$	36.6	$	105.8

Cash Flow Assumption Update Impacts to Income Before Income Tax	$	28.7	$	(478.5)
Cash Flow Assumption Update Impacts to Net Income	$	23.5	$	(377.8)

2026 Significant Cash Flow Assumption Updates:

The cash flow assumption updates in our Closed Block segment were primarily driven by the long-term care product line. The impact to income before income tax for this product line was $54.9 million. However, there were also updates to the assumptions for the portion of the long-term care product line which was included in the block ceded as a part of the 2025 Fortitude Re reinsurance transaction. We increased our liability for future policy benefits by $53.1 million as a result of the assumption updates related to the ceded block with a corresponding increase in our consolidated balance sheet as a reinsurance recoverable. The total cash flow assumption updates in the long-term care product line increased our liability for future policy benefits due primarily to higher expectations for claim incidence assumptions and lower expectations for mortality assumptions, partially offset by an increase to expected future premium rate approvals.

The cash flow assumption updates in our Colonial Life segment reduced our liability for future policy benefits by $42.5 million, due primarily to lower expectations for morbidity assumptions, increased policyholder lapse rates, and lower mortality assumptions.

The cash flow assumption updates in our Unum US group disability product line reduced our liability for future policy benefits by $36.6 million, due primarily to favorable social security benefit offsets and claim recovery trends, partially offset by higher claim incidence.

The cash flow assumption updates in our Unum International segment increased our liability for future policy benefits by $27.3 million, due primarily to higher claim incidence assumptions for our Unum UK group disability product line.

Table of Contents

2025 Significant Cash Flow Assumption Updates:

The cash flow assumption updates in our Closed Block segment were primarily driven by the long-term care product line. The impact to income before income tax for this product line was $643.1 million. However, there were also updates to the assumptions for the portion of the long-term care product line which was included in the block ceded as a part of the 2025 Fortitude Re reinsurance transaction. We increased our liability for future policy benefits by $82.0 million as a result of the assumption updates related to the ceded block with a corresponding increase in our consolidated balance sheet as a reinsurance recoverable. The total cash flow assumption updates in the long-term care product line increased our liability for future policy benefits due primarily to the removal of the morbidity and mortality improvement assumptions. Also contributing were higher expectations for claim incidence assumptions, and the removal of future assumptions related to new enrollments on existing group cases, partially offset by an increase to expected future premium rate approvals and higher expectations for claim terminations.

The cash flow assumption updates in our Unum US group long-term disability product line reduced our liability for future policy benefits by $105.8 million, due primarily to claim resolution assumptions driven by favorable claim recovery trends as well as higher mortality expectations.

The cash flow assumption updates in our Unum US individual disability product line reduced our liability for future policy benefits by $27.7 million, due primarily to favorable claim incidence and recovery trends.

Fluctuations in exchange rates, particularly between the British pound sterling and the U.S. dollar for our U.K. operations, have an effect on our consolidated financial results. In periods when the pound weakens relative to the preceding period, translating pounds into dollars decreases current period results relative to the prior period. In periods when the pound strengthens, translating pounds into dollars increases current period results relative to the prior period.

The weighted average pound/dollar exchange rate for our Unum UK line of business was 1.344 and 1.348 for the three months ended September 30, 2026 and 2025, and 1.345 and 1.314 for the nine months ended September 30, 2026 and 2025, respectively. If the 2025 results for our U.K. operations had been translated at the weighted average exchange rates of 2026, our adjusted operating revenue would have been lower by approximately $1 million in the third quarter of 2025 and higher by approximately $16 million in the first nine months of 2025. Our adjusted operating income for the third quarter of 2025 would have been generally consistent and our adjusted operating income would have been higher by approximately $3 million for the first nine months of 2025. Except for a limited number of transactions, we do not actually convert pounds into dollars. As a result, we view foreign currency translation as a financial reporting item and not a reflection of operations or profitability in the U.K.

Premium income increased in each of our core operating segments in the third quarter and first nine months of 2026 compared to the same periods of 2025, primarily due to sales in the Unum US segment as well as higher persistency in the Unum US group product lines, partially offset by the expected run off in medical stop-loss premium and lower persistency in the Unum US supplemental and voluntary product lines. Also partially offsetting the increase in the first nine months of 2026 compared to 2025 is the impact of ceding a portion of Unum US individual disability product line as part of the 2025 Fortitude Re reinsurance transaction. Premium income continues to decline in our Closed Block segment, as expected, and, for the comparison of the first nine months of 2026 to the same period of 2025, this was accelerated by the impact of ceding a portion of the Closed Block long-term care product line as a part of the 2025 Fortitude Re reinsurance transaction.

102

Table of Contents

Net investment income was higher in the third quarter compared to the same period of 2025 due primarily to an increase in the yield on invested assets and higher miscellaneous investment income. Net investment income was lower in the first nine months of 2026 compared to the same period of 2025 due primarily to a decrease in the level of invested assets supporting the Closed Block long-term care product line as a result of the 2025 Fortitude Re reinsurance transaction and depreciation expense associated with real estate previously held for sale reclassified to real estate held for the production of income, partially offset by higher yield on invested assets.

Our investment gains and losses for the third quarter and first nine months of 2026 were driven primarily by the 2026 Fortitude Re reinsurance transaction which resulted in a net loss of $833.5 million in the third quarter and first nine months of 2026. This loss was primarily due to impairment losses based on the intent to transfer fixed maturity securities supporting the 2026 Fortitude Re reinsurance transaction. Our investment gains and losses for the third quarter and first nine months of 2025 were driven primarily by the 2025 Fortitude Re reinsurance transaction which resulted in a net gain of $137.6 million in the third quarter of 2025 and a net loss of $46.8 million in the first nine months of 2025. In addition, we realized a $19.1 million loss on sales of fixed maturity securities relating to funding of a dividend from one of our subsidiaries in the first nine months of 2025. See Note 4 in the "Notes to Consolidated Financial Statements" contained herein in Item 1 and "Investments" contained herein in this Item 2 for further information.

Other income is primarily comprised of fee-based service products in the Unum US segment, which include leave management services and administrative services only business and the underlying results and associated net investment income of certain assumed blocks of reinsured business in the Closed Block segment. Other income also includes the amortization of the deferred gain related to the 2025 Fortitude Re reinsurance transaction that began in the third quarter of 2025. Other income for the first nine months of 2025 primarily includes a gain on the recapture of a previously ceded block of business in the individual disability product line that occurred in the first quarter of 2025.

Overall benefits experience was favorable in the third quarter and first nine months of 2026 relative to the same periods of 2025. The consolidated benefit ratio, which includes the remeasurement gain or loss, was 74.1 percent and 72.3 percent in the third quarter and first nine months of 2026, respectively, compared to 86.5 percent and 75.8 percent for the same prior year periods. The underlying benefits experience for each of our operating segments is discussed more fully in "Segment Results" as follows.

Commissions and the deferral of acquisition costs were higher during the third quarter and first nine months of 2026 compared to the same periods of 2025 due to sales. The amortization of deferred acquisition costs was higher in the third quarter and first nine months of 2026 compared to the same periods of 2025 due to growth in the level of the deferred asset.

Other expenses and compensation expense, on a combined basis, in the third quarter of 2026 is generally consistent compared to the same period of 2025. Other expenses and compensation expense, on a combined basis, increased in the first nine months of 2026 compared to the same periods of 2025 due to an increase in the amortization of the cost of reinsurance as a result of the 2025 Fortitude Re reinsurance transaction.

Our effective income tax rates for the third quarter and first nine months of 2026 were 23.6 percent and 16.4 percent of income before income tax, respectively, compared to 27.2 percent and 21.1 percent for the same prior year periods. Our effective income tax rate differed from the U.S. statutory rate of 21 percent for the third quarter and first nine months of 2026 primarily due to the release of unrecognized tax benefits due to completion of an IRS exam partially offset by a valuation allowance related to our deferred tax assets on capital losses. Our effective tax rate differed from the U.S. statutory rate of 21 percent for the third quarter of 2025 primarily due to global intangible low taxed income tax and interest on uncertain tax positions, partially offset by tax exempt income and prior year tax return true-up. Our effective income tax rate was generally consistent with the U.S. statutory rate of 21 percent in effect for the first nine months of 2025, with interest on uncertain tax positions mostly offset by tax exempt income.

Consolidated Sales Results

Shown below are sales results for our three principal operating business segments.

(in millions)
	Three Months Ended September 30						Nine Months Ended September 30
	2026		% Change		2025		2026		% Change		2025
Unum US	$	163.9	(8.5)	%	$	179.1	$	780.8	8.6	%	$	719.0
Unum International	$	29.0	(41.6)	%	$	49.7	$	123.5	(18.5)	%	$	151.6
Colonial Life	$	132.6	6.4	%	$	124.6	$	373.0	4.7	%	$	356.4

Sales shown in the preceding chart generally represent the annualized premium income on new sales which we expect to receive and report as premium income during the next 12 months following or beginning in the initial quarter in which the sale is reported, depending on the effective date of the new sale. Sales do not correspond to premium income reported as revenue in accordance with GAAP. This is because new annualized sales premiums reflect current sales performance and what we expect to recognize as premium income over a 12 month period, while premium income reported in our financial statements is reported on an "as earned" basis rather than an annualized basis and also includes renewals and persistency of in-force policies written in prior years as well as current new sales.

Sales, persistency of the existing block of business, employment and salary growth, and the effectiveness of a renewal program are indicators of growth in premium income. Trends in new sales, as well as existing market share, also indicate the potential for growth in our respective markets and the level of market acceptance of price levels and new product offerings. Sales results may fluctuate significantly due to case size and timing of sales submissions.

See "Segment Results" as follows for a discussion of sales by segment.

Segment Results

Our reportable segments are comprised of the following: Unum US, Unum International, Colonial Life, Closed Block, and Corporate.

In describing our results, we may at times note certain items and exclude the impact on financial ratios and metrics to enhance the understanding and comparability of our operational performance and the underlying fundamentals, but this exclusion is not an indication that similar items may not recur. We also measure and analyze our segment performance on the basis of "segment adjusted operating revenue" and "segment adjusted operating income" or "segment adjusted operating loss", which differ from total revenue and income before income tax as presented in our consolidated statements of operations due to the exclusion of investment gains and losses and certain other items. These performance measures are in accordance with GAAP guidance for segment reporting, but they should not be viewed as a substitute for total revenue, income before income tax, or net income. See "Reconciliation of Non-GAAP Financial Measures" contained herein in this Item 2.

Unum US Segment

The Unum US segment is comprised of the group disability, group life and accidental death and dismemberment, and supplemental and voluntary lines of business. The group disability line of business includes long-term disability, short-term disability and our fee-based service products. Long-term disability includes medical stop-loss products, and short-term disability includes paid family and medical leave products. The supplemental and voluntary line of business includes voluntary benefits, individual disability, and dental and vision products. These products, excluding medical stop-loss which is no longer actively marketed as of the third quarter of 2024, are marketed through our field sales personnel who work in conjunction with independent brokers and consultants.

Premium income increased in the third quarter and first nine months of 2026 compared to the same periods of 2025 due to sales and higher persistency, partially offset by the expected run off in medical stop-loss premium. Net investment income was higher in the third quarter of 2026 relative to the same period of 2025 due to an increase in the allocation of net investment income on corporate owned excess assets and higher miscellaneous investment income. Net investment income was higher in the first nine months of 2026 relative to the same period of 2025 due to an increase in the allocation of net investment income on corporate owned excess assets as well as an increase in yield on invested assets, partially offset by a decrease in the level of invested assets.

Other income was higher in the third quarter and first nine months of 2026 compared to the same periods of 2025 due to growth in our fee-based service products.

The benefit ratio was higher in the third quarter and first nine months of 2026 compared to the same periods of 2025 due to less favorable reserve assumption updates and refinements in the third quarter of 2026 compared to prior year, higher incidence, and prior period pricing actions. Also contributing to the higher benefit ratio in the third quarter of 2026 was higher average claim size in long-term disability.

Premium income was higher in the third quarter and first nine months of 2026 compared to the same periods of 2025 due to prior period sales in the voluntary benefits and dental and vision product lines, partially offset by lower persistency across all product lines. Also impacting the first nine months of 2026 is the impact of ceding a portion of the individual disability product line as a part of the 2025 Fortitude Re reinsurance transaction. Net investment income was higher in the third quarter and first nine months of 2026 compared to the same periods of 2025 due to an increase in yield on invested assets and higher miscellaneous income, partially offset by a decrease in the level of invested assets.

Group sales decreased during the third quarter of 2026 compared to the same period of 2025 due to lower sales to new customers in the large case market, which we define as employee groups with more than 2,000 employees, partially offset by higher sales to existing customers in the large case market. Group sales increased during the first nine months of 2026 compared to the same period of 2025 due primarily to higher sales to new customers in the core market and existing customers in the large case market, partially offset by lower sales to new customers in the large case market. The sales mix in the group market sector for the first nine months of 2026 was approximately 63 percent core market and 37 percent large case market.

Supplemental and voluntary sales decreased during the third quarter of 2026 compared to the same period of 2025 due primarily to lower sales for the individual disability and dental and vision product lines, partially offset by higher sales for the voluntary benefits product line. Supplemental and voluntary sales increased during the first nine months of 2026 compared to the same period of 2025 due to higher sales for the voluntary benefits product line.

Segment Outlook

We remain committed to offering consumers a broad set of financial protection benefit products at the worksite. During 2026, we will continue to invest in a unique customer experience defined by simplicity, empathy, and deep industry expertise through the increased utilization of digital capabilities and technology to enhance enrollment, underwriting, the client administration experience, and claims processing. In addition, we will focus on strategically driven sales by enhancing the connectivity, alignment, and support for brokers and technology partners, including integration with human capital management systems. We will continue to provide a comprehensive set of consumer-focused products, enhance our distribution model, and utilize our digital tools to bring industry leading enrollment capabilities and a fully integrated customer experience. We believe our differentiated offerings and market leading leave management services provide substantial growth opportunities and stronger persistency.

We believe our active client management, integrated customer experience across our product lines, and strong risk management, will enable us to continue to grow our market over the long-term.

Table of Contents

We expect Unum US segment adjusted operating income to be slightly lower in 2026 compared to 2025 due primarily to the change in reserve assumption updates. We also expect premium growth driven by new sales and persistency. We expect the group disability market to remain competitive which may impact our pricing and renewal premium levels. We expect elevated group disability claim experience to continue for the remainder of 2026, including pressure related to our paid family and medical leave products. We also expect group life claim experience to be generally consistent with prior year, but may experience some quarterly claims volatility. We expect claim experience in our supplemental and voluntary product line to be slightly elevated in 2026 compared to 2025 due primarily to the change in reserve assumption updates. We expect to maintain expense discipline with a slight decrease in our other expense ratio.

A rising interest rate environment could positively impact our yields on new investments, but could also increase unrealized losses in our current holdings. Alternatively, a declining interest rate environment could negatively impact yields on new investments, but could also reduce unrealized losses in our current holdings. Our net investment income may continue to be impacted by volatility in miscellaneous investment income.

As part of our discipline in pricing and reserving, we continuously monitor emerging claim trends and interest rates. We will continue to take appropriate pricing actions on new business and renewals that are reflective of the current environment.

We continuously monitor key indicators to assess our risks and adjust our business plans accordingly.

Foreign Currency Translation

The functional currencies of Unum UK and Unum Poland are the British pound sterling and Polish zloty, respectively. Premium income, net investment income, claims, and expenses are received or paid in the functional currency, and we hold functional currency-denominated assets to support functional currency-denominated policy liabilities. We translate functional currency-denominated financial statement items into dollars for our consolidated financial reporting. We translate income statement items using an average exchange rate for the reporting period, and we translate balance sheet items using the exchange rate at the end of the period. We report unrealized foreign currency translation gains and losses in accumulated other comprehensive income in our consolidated balance sheets.

Fluctuations in exchange rates impact Unum International's reported financial results and our consolidated financial results. In periods when the functional currency strengthens relative to the preceding period, translation increases current period results relative to the prior period. In periods when the functional currency weakens, translation decreases current period results relative to the prior period.

Premium income was higher in the third quarter and first nine months of 2026 compared to the same periods of 2025 primarily due to in-force block growth in the group life and supplemental product lines.

Net investment income was higher in the third quarter of 2026 compared to the same period of 2025 primarily due to higher yield on invested assets, partially offset by a decrease in the level of invested assets. Net investment income was lower in the first nine months of 2026 compared to the same periods of 2025 primarily due to lower income from inflation index-linked bonds and a decrease in the level of invested assets, partially offset by an increase in the yield on invested assets. Our investments in inflation index-linked bonds support the claim liabilities associated with certain group policies that provide for

112

inflation-linked increases in policy benefits. The change in net investment income attributable to these index-linked bonds is generally correlated to a change in policy benefits related to the inflation index-linked group long-term disability and group life policies.

Other income primarily relates to fees earned related to certain administrative services.

The benefit ratio was higher in the third quarter and first nine months of 2026 compared to the same periods of 2025 due primarily to unfavorable reserve assumption updates in the third quarter of 2026 compared to the prior year as well as higher average claim size and higher incidence in the group long-term disability product line.

Commissions and the deferral of acquisition costs were higher in the third quarter and first nine months of 2026 compared to the same periods of 2025 primarily due to new business. The amortization of deferred acquisition costs was generally consistent in the third quarter and first nine months of 2026 compared to the same periods of 2025.

The other expense ratio was lower in the third quarter and first nine months of 2026 compared to the same periods of 2025 due primarily to our focus on expense management and operating efficiencies.

The following discussion of sales results relates to our Unum UK product lines based on functional currency.

Group sales decreased in the third quarter and the first nine months of 2026 compared to the same periods of 2025 due primarily to lower sales to new customers in the large case market, which we define as employee groups with more than 500 employees, and lower sales to new customers in the core market.

Supplemental sales were generally consistent in the third quarter of 2026 compared to the same period of 2025. Supplemental sales decreased in the first nine months of 2026 primarily due to lower sales of our dental product.

Segment Outlook

We are committed to driving growth in the Unum International segment and will build on the capabilities that we believe will generate growth and profitability in our businesses over the long term. We will continue to focus on scaling our business across

113

our existing product portfolio. For our Unum UK line of business, we will continue to focus on delivering a best in class health and wellbeing service to improve retention of our key customers and drive growth across our product offerings. We also expect to deliver continued premium growth by focusing on both the broker experience and customer engagement, while maintaining our disciplined approach to pricing. We expect group long-term disability claim experience for the remainder of 2026 to be mostly in line with the first nine months of the year. We expect to maintain expense discipline with a decrease in our other expense ratio. Within our Unum Poland line of business, we expect to drive growth by continuing to expand our existing distribution channels. We will also continue to invest in digital capabilities, technology, and product enhancements which we believe will drive sustainable growth over the long term. We continuously monitor key indicators to assess our risks and adjust our business plans accordingly.

Public sector sales increased in the third quarter and first nine months of 2026 compared to the same periods of 2025 due to higher sales to new and existing customers.

Segment Outlook

We remain committed to providing employees and their families with simple, modern, and personal benefit solutions. By continuing to utilize our extensive distribution system of independent agents, benefit counselors and broker partnerships during 2026, we believe we will deliver business growth. We will also continue to invest in solutions and digital capabilities to expand our reach and effectiveness, which we believe will drive growth and improve productivity while enhancing the customer experience. In 2026, we will continue to bring an enhanced engagement and enrollment platform to market, which we believe will enable deeper connections with employees through the enrollment process and help us maintain stronger relationships throughout the customer lifecycle. We believe our distribution system, customer service capabilities, digital tools, and ability to serve all market sizes position us well for future growth.

In 2026, we expect growth in segment adjusted operating income for the full year with continued premium growth and stable claim experience. We continuously monitor key indicators to assess our risks and adjust our business plans accordingly.

Closed Block Segment

The Closed Block segment consists of group and individual long-term care and other insurance products no longer actively marketed. We discontinued offering individual long-term care in 2009 and group long-term care in 2012. In July 2025, we closed the 2025 Fortitude Re reinsurance transaction and ceded a portion of the long-term care product line. In February 2026, we discontinued new enrollments on existing group long-term care policies. Other insurance products include individual disability, group pension, individual life and corporate-owned life insurance, reinsurance pools and management operations, and other miscellaneous product lines.

1Gross of reinsurance

Premium income for the long-term care product line was higher in the third quarter of 2026 compared to the same period of 2025 due to premium rate increases, partially offset by group policy terminations. Premium income for the long-term care product line was lower in the first nine months of 2026 compared to the same period of 2025 due to the impact of the 2025 Fortitude Re reinsurance transaction. Premium income for our all other product line continues to decline as expected due to policyholder lapses.

Net investment income was higher during the third quarter of 2026 relative to the same period of 2025 primarily due to an increase in the yield on invested assets as well as higher miscellaneous investment income, primarily related to larger increases in the NAV on our private equity partnerships, partially offset by a decrease in the level of invested assets and a decrease in the allocation of net investment income from our corporate owned excess assets. Net investment income was lower during the first nine months of 2026 relative to the same period of 2025 primarily due to a decrease in the level of invested assets resulting from the Fortitude Re reinsurance transaction and a decrease in the allocation of net investment income from our corporate

Table of Contents

owned excess assets, partially offset by higher miscellaneous investment income, primarily related to larger increases in the NAV on our private equity partnerships.

Other income primarily includes the underlying results and associated net investment income of certain assumed blocks of business.

Policy benefits including remeasurement loss were lower in the third quarter and first nine months of 2026 compared to the same periods of 2025 driven primarily by less unfavorable reserve assumption updates compared to prior year, partially offset by policy terminations and related port activity for our group long-term care product line. Also impacting the comparison for the first nine months of 2026 compared to the same period of 2025 is the impact of the 2025 Fortitude Re reinsurance transaction. The net premium ratio for long-term care increased to 98.1 percent at September 30, 2026 from 97.6 percent at September 30, 2025 due primarily to policy terminations and related port activity for our group long-term care product line.

The other expense ratio was lower in the third quarter of 2026 compared to the same period of 2025 and higher in the first nine months of 2026 compared to the same period of 2025 due to the amortization of the cost of reinsurance as a result of the 2025 Fortitude Re reinsurance transaction. As the transaction closed in the third quarter of 2025, only one quarter of the first nine months of 2025 was impacted.

Segment Outlook

We will continue to execute on our well-defined strategy of implementing long-term care premium rate increases, efficient capital management, improved financial analysis, and operational effectiveness. In regard to capital management, we will continue to explore, and execute where appropriate, structural and reinsurance options to enhance financial flexibility.

Premium income is primarily related to the retained portion of our long-term care product line as the majority of other closed product lines have been ceded to third parties. Although our group and individual long-term care products are no longer actively marketed, these guaranteed renewable policies remain in force and we continue to collect premiums where coverage remains active. Premium income is recognized as policyholders continue to pay for ongoing insurance coverage under existing contracts. Given the long duration of the product, premium income for the retained portion of our long-term care product line is expected to run off over the next approximately 30 years depending on factors such as policy persistency, morbidity, mortality, and premium rate actions as these closed blocks of business wind down, and with the discontinuation of new enrollments on existing group long-term care policies as of February 2026.

We continue to file requests with various state insurance departments for premium rate increases on certain of our individual and group long-term care policies which reflect assumptions as of the date of filings. In states for which a rate increase is submitted and approved, we routinely provide customers options for coverage changes or other approaches that might fit their current financial and insurance needs.

We will likely experience volatility in net investment income due to fluctuations of miscellaneous investment income, driven by the allocation towards alternative assets, primarily private equity partnership investments, in the long-term care product line portfolio. We record changes in our share of the NAV of the partnerships in net investment income. We receive financial information related to our investments in partnerships and generally record investment income on a one-quarter lag in accordance with our accounting policy. As these NAVs are volatile and can fluctuate materially with changes in market economic conditions, there could be significant movements up or down in future periods as conditions change. We continuously monitor key indicators to assess our risks and adjust our business plans, including utilization of derivative financial instruments to manage interest rate risk.

Profitability of our long-tailed products is affected by claims experience related to mortality, morbidity, resolutions, investment returns, premium rate increases, and persistency. The net premium ratio represents the ratio of future expected benefits and related expenses to future expected gross premiums using the original discount rate. Long-term care benefits experience may continue to have quarterly volatility, particularly in the near term as our claim block matures and as we continue the implementation of premium rate increases. Claim resolution rates which reflect the probability that a disability or long-term care claim will close due to recovery or death of the insureds, are very sensitive to operational and external factors and can be volatile. Our claim resolution rate assumption used in determining reserves is our expectation of the resolution rate we will experience over the life of the block of business and will vary from actual experience in any one period. It is possible that variability in any of our reserve assumptions, including, but not limited to, mortality, morbidity, resolutions, premium rate increases, benefit change elections, and persistency, could result in a material impact to our reserves.

118

Table of Contents

We expect Closed Block segment adjusted operating income (loss) in subsequent periods will primarily be impacted by the amortization of the cost of reinsurance, the impact of non-contemporaneous reinsurance related to recent reinsurance transactions, the impacts from group policy terminations over the near term, and the allocation of net investment income from our corporate owned excess assets which support the capital allocated to this segment.

As a result of the execution of previous reinsurance transactions related to our Closed Block individual disability and long-term care lines of business, we have ceded a significant portion of this business.

As previously discussed, we entered into a reinsurance agreement with Fortitude Re to cede an additional portion of our long-term care business during November 2026. For further discussion, see “Executive Summary" contained herein in Item 2 and Note 14 of the “Notes to Consolidated Financial Statements” contained herein in Item 1.

Corporate Segment

The Corporate segment includes investment income on corporate assets not specifically allocated to a line of business, interest expense on corporate debt, and certain other corporate income and expenses not allocated to a line of business.

Segment adjusted operating loss decreased in the third quarter of 2026 relative to the same period of 2025 due primarily to higher net investment income, which was driven by an increase in the level of invested assets, partially offset by a decrease in the yield on invested assets. Segment adjusted operating loss, excluding the impact of the strategic actions, increased in the first nine months of 2026 relative to the same period of 2025 due primarily to lower net investment income, which was driven by a decrease in the yield on invested assets and a decrease in miscellaneous investment income, partially offset by an increase in the level of invested assets. See "Executive Summary" contained herein this Item 2 and Note 14 of the "Notes to Consolidated Financial Statements" contained herein in Item 1 for further discussion on the strategic actions.

Segment Outlook

We expect to continue to generate excess capital on an annual basis through the statutory earnings in our insurance subsidiaries and believe we are well positioned with flexibility to preserve our capital strength while also returning capital to our shareholders. We may experience volatility in net investment income due to changes in the prevailing interest rates, miscellaneous investment income, and the composition and level of invested assets.

Investments

Overview

Investment activities are an integral part of our business, and profitability is significantly affected by investment results. We segment our invested assets into portfolios that support our various product lines. Generally, our investment strategy for our portfolios is to match the effective asset cash flows and durations with related expected liability cash flows and durations to consistently meet the liability funding requirements of our businesses and to manage interest rate risk. We seek to earn investment income while assuming risk in a prudent and selective manner, subject to the constraints of quality, liquidity, diversification, and regulatory considerations. Our overall investment philosophy is to invest in a portfolio of high quality assets that provide investment returns which inform the assumptions embedded in the pricing of our insurance products. Assets are invested predominantly in fixed maturity securities.

We may redistribute investments among our different lines of business or sell selected securities and reinvest the proceeds, when necessary, to adjust the cash flow and/or duration of the asset portfolios to better match the cash flow and duration of the liability portfolios. Asset and liability portfolio modeling is updated on a quarterly basis and is used as part of the overall interest rate risk management strategy. Cash flows from the in-force asset and liability portfolios are projected at current interest rate levels and at levels reflecting an increase and a decrease in interest rates to obtain a range of projected cash flows under the different interest rate scenarios. These results enable us to assess the impact of projected changes in cash flows and duration resulting from potential changes in interest rates. Testing the asset and liability portfolios under various interest rate scenarios enables us to choose what we believe to be the most appropriate investment strategy, as well as to limit the risk of disadvantageous outcomes. Although we test the asset and liability portfolios under various interest rate scenarios as part of our modeling, the majority of our liabilities related to insurance contracts are not interest rate sensitive, and we therefore have minimal exposure to policy withdrawal risk. Our determination of investment strategy relies on long-term measures such as asset adequacy analysis and the relationship between the portfolio yields supporting our various product lines and the aggregate discount rate assumptions embedded in the reserves. We also utilize quantitative strategic asset analysis to construct our investment strategy, utilizing projected asset class risk and returns to inform an appropriate liability-driven investment approach. Additionally, we also use this analysis in determining hedging strategies and utilizing derivative financial instruments to manage interest rate risk and the risk related to matching duration for our assets and liabilities. We do not use derivative financial instruments for speculative purposes.

Our investment portfolio is well diversified by type of investment and industry sector. We have established an investment strategy that we believe will provide adequate cash flows from operations and allow us to hold our securities through periods where significant decreases in fair value occur. We believe our emphasis on risk management in our investment portfolio has positioned us well and generally reduced the volatility in our results.

2026 Closed Block Long-Term Care Reinsurance Transaction

As part of the 2026 Fortitude Re reinsurance transaction, which closed in November 2026, we transferred fixed maturity securities with an amortized cost of $5,047.6 million and a fair value of $5,080.5 million as of September 30, 2026. During the third quarter of 2026, we recognized impairment losses totaling $754.4 million based on our intent to transfer these assets. In addition, we realized $51.9 million loss on forward benchmark interest rate locks and $27.2 million loss of total return swaps to hedge interest rate and duration risk associated with assets that were transferred upon closing of the 2026 Fortitude Re reinsurance transaction. As of September 30, 2026, the portfolio we transferred had a total unrealized gain of $32.9 million which is subject to change based on interest rate and credit spread environments at time of closing. Although we transferred a significant portion of our fixed maturity securities portfolio as part of this transaction, the overall credit profile of our remaining portfolio did not change. See "Executive Summary" for further information on the 2026 Fortitude Re reinsurance transaction contained herein in this Item 2.

The following two tables show the length of time our investment-grade and below-investment-grade fixed maturity securities portfolios had been in a gross unrealized loss position as of September 30, 2026 and at the end of the prior four quarters. The relationships of the current fair value to amortized cost are not necessarily indicative of the fair value to amortized cost relationships for the securities throughout the entire time that the securities have been in an unrealized loss position nor are they necessarily indicative of the relationships after September 30, 2026. During the third quarter of 2026, the net unrealized loss position increased due primarily to an increase in U.S. Treasury yields partially offset by investment losses recorded on certain fixed maturity securities related to the 2026 Fortitude Re reinsurance transaction.

As of September 30, 2026, we held 67 investment-grade fixed maturity securities with a gross unrealized loss of $10.0 million or greater as shown in the chart below.

At September 30, 2026, we held one below investment-grade fixed maturity security with a gross unrealized loss greater than $10.0 million. The security is a utilities company and had a fair value of $34.6 million and a gross unrealized loss of $10.8 million.

Unrealized losses on investment-grade fixed maturity securities principally relate to changes in interest rates or changes in market or sector credit spreads which occurred subsequent to the acquisition of the securities. Below-investment-grade fixed maturity securities are generally more likely to develop credit concerns than investment-grade securities. At September 30, 2026, the unrealized losses in our below-investment-grade fixed maturity securities were generally due to higher interest rates, wider credit spreads in certain industries or sectors and, to a lesser extent, credit concerns related to specific securities. For each specific security in an unrealized loss position, we believe that there are positive factors which mitigate credit concerns and that the securities for which we have not recorded a credit loss will recover in value. We have the ability and intent to continue to hold these securities to recovery of amortized cost less allowance for credit losses.

During the second quarter of 2025, we recognized a realized loss of $13.4 million on the sale of fixed maturity securities from a single issuer in the communications sector. We had no other individual net investment losses of $10.0 million or greater from credit losses or sales of fixed maturity securities during the first nine months of 2026 or 2025.

As of September 30, 2026, the amortized cost, net of allowance for credit losses, and fair value of our below-investment-grade fixed maturity securities was $1,262.7 million and $1,193.8 million, respectively, and our below-investment-grade fixed maturity securities as a percentage of our total investment portfolio was 2.8 percent at both December 31, 2025 and September 30, 2026 on a fair value basis. Below-investment-grade securities are inherently riskier than investment-grade securities since the risk of default by the issuer, by definition and as exhibited by bond rating, is higher. Also, the secondary market for certain below-investment-grade issues can be highly illiquid. Additional downgrades may occur, but we do not anticipate any liquidity problems resulting from our investments in below-investment-grade securities, nor do we expect these investments to adversely affect our ability to hold our other investments to maturity.

124

Fixed Maturity Securities - Foreign Exposure

Our investments in issuers in foreign countries are chosen for specific portfolio management purposes, including asset and liability management and portfolio diversification across geographic lines and sectors to minimize non-market risks. In our approach to investing in fixed maturity securities, specific investments within approved countries and industry sectors are evaluated for their market position and specific strengths and potential weaknesses.  For each security, we consider the political, legal, and financial environment of the sovereign entity in which an issuer is domiciled and operates. The country of domicile is based on consideration of the issuer's headquarters, in addition to location of the assets and the country in which the majority of sales and earnings are derived.  We do not have exposure to foreign currency risk, as the cash flows from these investments are either denominated in currencies or hedged into currencies to match the related liabilities. We continually evaluate our foreign investment risk exposure.

Mortgage Loans

The carrying value of our mortgage loan portfolio was $2,053.2 million and $2,109.5 million at September 30, 2026 and December 31, 2025, respectively. Our investments in mortgage loans are carried at amortized cost less an allowance for expected credit losses which was $16.4 million and $15.9 million at September 30, 2026 and December 31, 2025, respectively. Our mortgage loan portfolio is comprised entirely of commercial mortgage loans. Our mortgage loan portfolio is well diversified geographically and among property types.

Due to conservative underwriting, the incidence of non-performing mortgage loans and foreclosure activity continues to be low. Other than our allowance for expected credit losses, we held no specifically identified impaired mortgage loans at September 30, 2026 and December 31, 2025. See Note 4 in the "Notes to Consolidated Financial Statements" contained herein in Item 1 for further discussion of our mortgage loan portfolio and the allowance for expected credit losses.

Private Equity Partnerships

The carrying value of our investments in private equity partnerships was $1,448.1 million and $1,456.3 million at September 30, 2026 and December 31, 2025, respectively. These partnerships are passive in nature and represent funds that are primarily invested in private credit, private equity, and real assets. The carrying value of the partnerships is based on our share of the partnership's NAV and changes in the carrying value are recorded as a component of net investment income. We receive financial information related to our investments in partnerships and generally record investment income on a one-quarter lag in accordance with our accounting policy. We recorded net investment income totaling $36.4 million and $80.4 million for the partnerships in the third quarter and the first nine months of 2026, respectively. The majority of our investments in partnerships are not redeemable. Distributions received from the funds arise from income generated by the underlying investments as well as the liquidation of the underlying investments. There is generally not a public market for these investments. See Note 3 in the "Notes to Consolidated Financial Statements" contained herein in Item 1 for further discussion of our private equity partnerships.

Derivative Financial Instruments

We use derivative financial instruments primarily to manage interest rate risk, risk related to matching duration for our assets and liabilities, foreign currency risk, and equity risk. Historically, we have utilized current and forward interest rate swaps, current and forward currency swaps, forward benchmark interest rate locks, currency forward contracts, forward contracts on specific fixed income securities, and total return swaps. As of September 30, 2026, we had $5,157.0 million in notional amount of derivatives outstanding, of which $2,311.0 million is related to management of reinvestment risk in our long-term care product line, $1,085.9 million is related to management of foreign currency risk related to foreign denominated investments, and $172.5 million is economically hedging a portion of the liability related to our non-qualified defined contribution plan. During the third quarter of 2026, we entered into $549.8 million of total return swaps and $832.0 million of forward benchmark interest rate locks to economically hedge interest rate and duration risk associated with a portion of the consideration payable upon closing of the 2026 Fortitude Re reinsurance transaction. We also entered into $205.8 million of interest rate swaps to economically hedge interest rate risk associated with certain floating rate liabilities. Credit exposure on derivatives is limited to the value of those contracts in a net gain position, including accrued interest receivable less collateral held. Our credit exposure on derivatives was $2.2 million at September 30, 2026. The carrying value of fixed maturity securities received from our counterparties was $1.0 million at September 30, 2026. We received a de minimis amount of cash collateral from our counterparties at September 30, 2026. The carrying value of fixed maturity securities and cash posted as collateral to our counterparties was $439.6 million and $7.7 million, respectively, at September 30, 2026. We believe that our credit risk is mitigated by our use of multiple counterparties, all of which have an investment-grade credit rating, and by our use of cross-

125

collateralization agreements. See Note 5 in the "Notes to Consolidated Financial Statements" contained herein in Item 1 for further discussion of our derivatives.

For further information see "Investments" in Part I, Item 1 and "Critical Accounting Estimates" and "Investments" in Part II, Item 7 of our annual report on Form 10-K for the year ended December 31, 2025, and Notes 3, 4, and 5 of the "Notes to Consolidated Financial Statements" contained herein in Item 1.

Liquidity and Capital Resources

Overview

Our liquidity requirements are met primarily by cash flows provided from operations, principally in our insurance subsidiaries. Premium and investment income, as well as maturities and sales of invested assets, provide the primary sources of cash. Debt and/or securities offerings provide additional sources of liquidity. Cash is applied to the payment of policy benefits, costs of acquiring new business (principally commissions), operating expenses, and taxes, as well as purchases of new investments.

We have established an investment strategy that we believe will provide for adequate cash flows from operations. We attempt to match our asset cash flows and durations with expected liability cash flows and durations to meet the funding requirements of our business. However, deterioration in the credit market may delay our ability to sell our positions in certain of our fixed maturity securities in a timely manner and adversely impact the price we receive for such securities, which may negatively impact our cash flows. Furthermore, if we experience defaults on securities held in the investment portfolios of our insurance subsidiaries, this will negatively impact statutory capital, which could reduce our insurance subsidiaries' capacity to pay dividends to our holding companies. A reduction in dividends to our holding companies could force us to seek external financing to avoid impairing our ability to pay dividends to our stockholders or meet our debt and other payment obligations.

Our policy benefits are primarily in the form of claim payments, and we have minimal exposure to the policy withdrawal risk associated with deposit products such as individual life policies or annuities. A decrease in demand for our insurance products or an increase in the incidence of new claims or the duration of existing claims could negatively impact our cash flows from operations. However, our historical pattern of benefits paid to revenues is generally consistent, even during cycles of economic downturns, which serves to minimize liquidity risk.

The liquidity requirements of the holding company Unum Group include common stock dividends, interest and debt service, and ongoing investments in our businesses.  Unum Group's liquidity requirements are met by assets held by Unum Group and our intermediate holding companies, dividends primarily from our insurance subsidiaries, and issuance of common stock, debt, or other capital securities and borrowings from our existing credit facility, as needed. As of September 30, 2026, Unum Group and our intermediate holding companies had available holding company liquidity of $1,383.4 million that was held primarily in bank deposits, commercial paper, money market funds, corporate bonds, municipal bonds and asset-backed securities.  No significant restrictions exist on our ability to use or access funds in any of our U.S. or foreign intermediate holding companies. Dividends repatriated from our foreign subsidiaries are eligible for 100 percent exemption from U.S. income tax but may be subject to withholding tax and/or tax on foreign currency gain or loss.

As part of the 2026 Fortitude Re reinsurance transaction, which closed in November 2026, we transferred fixed maturity securities and cash with a fair value of $5,500.7 million. A final settlement adjustment is expected prior to the end of the first quarter of 2027. The reinsurance transaction is funded using a combination of excess capital from Fairwind and holding company liquidity with additional external financing anticipated.

See "Executive Summary" contained herein in Item 2, and Note 14 in the "Notes to Consolidated Financial Statements" contained herein in Item 1 for further discussion of this transaction.

As part of our capital deployment strategy, we may repurchase shares of Unum Group's common stock, as authorized by our board of directors. The timing and amount of repurchase activity is based on market conditions and other considerations, including the level of available cash, alternative uses for cash, and our stock price. During the nine months ended September 30, 2026, we repurchased 10.0 million shares at a cost of $798.5 million excluding commissions and excise tax.

Cash Available from Subsidiaries

Unum Group and certain of its intermediate holding company subsidiaries depend on payments from subsidiaries to pay dividends to stockholders, to pay debt obligations, and/or to pay expenses. These payments by our insurance and non-insurance subsidiaries may take the form of dividends, operating and investment management fees, and/or interest payments on loans from the parent to a subsidiary.

Restrictions under applicable state insurance laws limit the amount of dividends that can be paid to a parent company from its insurance subsidiaries in any 12-month period without prior approval by regulatory authorities. For life insurance companies domiciled in the U.S., that limitation generally equals, depending on the state of domicile, either ten percent of an insurer's statutory surplus with respect to policyholders as of the preceding year end or the statutory net gain from operations, excluding realized capital gains and losses, of the preceding year. The payment of dividends to a parent company from a life insurance subsidiary is generally further limited to the amount of unassigned funds.

Unum America cedes blocks of long-term care business to Fairwind, which is an affiliated captive reinsurance subsidiary domiciled in the United States. The ability of Fairwind to pay dividends to Unum Group will depend on its satisfaction of applicable regulatory requirements and on the performance of the business reinsured by Fairwind. Unum Group did not make any capital contributions to Fairwind during the first nine months of 2026, nor do we expect to make capital contributions for the remainder of the year.

The ability of Unum Group and certain of its intermediate holding company subsidiaries to continue to receive dividends from their insurance subsidiaries also depends on additional factors such as RBC ratios and capital adequacy and/or solvency requirements, funding growth objectives at an affiliate level, and maintaining appropriate capital adequacy ratios to support desired ratings. The RBC ratios for our U.S. insurance subsidiaries at September 30, 2026 are above our long-term expectations and are significantly above the level that would require state regulatory action.

Unum Group and/or certain of its intermediate holding company subsidiaries may also receive dividends from our U.K. subsidiaries, the payment of which may be subject to applicable insurance company regulations and capital guidance in the U.K. Unum Limited is subject to the requirements of U.K. Solvency II, the system of prudential regulation applying in the U.K., which prescribes capital requirements and risk management standards for the U.K. insurance industry. Our U.K. holding company is also subject to the U.K. Solvency II requirements relevant to insurance holding companies, while its subsidiaries (the Unum UK Solvency II Group), which includes Unum Limited, are subject to group and individual supervision under U.K. Solvency II. The Unum UK Solvency II Group has permission from the PRA to use certain adjustments as well as a transitional measure which applies until January 2032. The Unum UK Solvency II Group also has permission to use its own internal model for calculating regulatory capital.

The payment of dividends to the parent company from our subsidiaries also requires the approval of the individual subsidiary's board of directors.

During 2026, we intend to maintain a level of capital in our insurance subsidiaries above the applicable capital adequacy requirements and minimum solvency margins. Approximately $631 million is available, without prior approval by regulatory authorities, during 2026, for the payment of dividends from Unum Group's traditional U.S. insurance subsidiaries, which

127

excludes our captive reinsurer. Unum Group has received $256.0 million of ordinary dividends from its traditional U.S. insurance subsidiaries during the nine months ended September 30, 2026.

Approximately £125 million is available for distribution from Unum Limited during 2026. The actual amount distributable during 2026 will depend on experience, including the impact of market movements, and is subject to local requirements, as well as regulatory and other business considerations.

Insurance regulatory restrictions do not limit the amount of dividends available for distribution from non-insurance subsidiaries except where the non-insurance subsidiaries are held directly or indirectly by an insurance subsidiary and only indirectly by Unum Group, which does not apply to our current entity structure.

Funding Agreement-Backed Loan Program

During February 2026, we established a funding agreement-backed loan (FABL) program, pursuant to which a special purpose unaffiliated Delaware statutory trust (the FABL trust) may borrow funds under a six-month delayed draw term loan facility (the facility) and deposit the proceeds with Colonial Life & Accident Insurance Company (Colonial Life & Accident), a wholly owned insurance subsidiary, pursuant to funding agreements issued by Colonial Life & Accident to the FABL trust. Colonial Life & Accident does not hold any variable interests in the FABL trust. The deposits received by Colonial Life & Accident under the funding agreements will be used for spread lending purposes. The facility permits borrowings by the FABL trust in two tranches, in an aggregate principal amount of up to $500.0 million, with scheduled maturities on the third and fifth anniversaries, respectively, of the date that is six months after the date of the applicable credit agreement. The funding agreements issued by Colonial Life & Accident will have matching interest, maturity and payment terms to the applicable borrowings by the FABL trust. The funding agreements may be collateralized by eligible securities, including agency securities, corporate bonds, municipal bonds, and U.S. Treasury securities. As of September 30, 2026, the funding agreements had been fully collateralized and Colonial Life & Accident had principal outstanding of $500.0 million which are included in policyholders' account balances on the consolidated balance sheets.

Debt, Credit Facilities, and Other Sources of Liquidity

Our long-term debt balance at September 30, 2026 was $3,765.7 million, net of a net discount of $125.6 million and deferred debt issuance costs of $34.5 million, and is comprised of unsecured senior notes, unsecured medium-term notes, and junior subordinated debt securities.

In November 2026, Provident Life and Accident Insurance Company (Provident), one of our traditional U.S. life insurance subsidiaries, entered into a five-year senior standby letter of credit facility to support potential funding obligations under the experience volatility cover related to the 2026 Fortitude Re reinsurance transaction with an initial commitment of $139.1 million, and annual increases up to a maximum of $172.4 million. The facility has an initial maturity date in November 2031 and is automatically extended annually for an additional twelve-month period, unless terminated. If the letter of credit is drawn, reimbursement would have interest based on the prime rate. As of the date of this filing, a letter of credit totaling $139.1 million had been issued.

In July 2026, we terminated our five-year, £75.0 million senior unsecured standby letter of credit facility, which was originally set to expire in December 2028. Also, our additional five-year, £75.0 million senior unsecured standby letter of credit facility expired, as scheduled, in July 2026. There were no borrowed amounts outstanding at the time of termination or expiration of these facilities.

Also in July 2026, we entered into a new five-year, £75.0 million senior standby letter of credit facility pursuant to which a £75.0 million letter of credit was issued in favor of Unum Limited (as beneficiary), our U.K. insurance subsidiary, and is available for borrowings up to £75.0 million until its scheduled expiration in July 2031. The credit facility provides for borrowings at an interest rate based on the Sterling Overnight Index Average rate. The credit facility may be collateralized by cash and eligible securities, including asset-backed securities, agency securities, corporate bonds and U.S. Treasury securities. As of September 30, 2026, the credit facility has not been collateralized. As of September 30, 2026, there were no borrowed amounts outstanding under the credit facility.

In April 2026, we entered into a senior standby letter of credit facility pursuant to which a £50.0 million letter of credit was issued in favor of Unum Limited (as beneficiary). The facility provides for drawings up to £50.0 million until its scheduled expiration five years after issuance of the letter of credit and no later than July 2031. The credit facility provides for borrowings at an interest rate based on the Sterling Overnight Index Average Rate. The credit facility may be collateralized by

128

cash and eligible securities, including U.S. Treasury securities. As of September 30, 2026, the credit facility was fully collateralized. No amounts have been drawn on the letter of credit.

During the first quarter of 2026, we purchased and retired $7.7 million aggregate principal amount of our 6.250% junior subordinated debt securities issued in 2018 and due in 2058.

We and certain of our traditional U.S. life insurance subsidiaries, Unum America, Provident and Colonial Life & Accident, are parties to a credit agreement providing for a five-year $500.0 million senior unsecured revolving credit facility with a syndicate of lenders. The revolving credit facility is set to expire in April 2030. We may request that the lenders’ aggregate commitments of $500.0 million under the facility be increased by up to an additional $200.0 million. Other of our domestic wholly-owned subsidiaries are permitted to join the credit facility as borrowers, subject to certain conditions. Any obligation of a subsidiary under the credit facility is subject to an unconditional guarantee by Unum Group. At September 30, 2026, there were no borrowed amounts outstanding under the revolving credit facility and letters of credit totaling $1.3 million had been issued.

There are no significant financial covenants associated with any of our debt obligations other than our borrowings under the credit facilities, which are subject to financial covenants, negative covenants, and events of default that are customary. Each credit facility includes financial covenants based on our leverage ratio and consolidated net worth as well as covenants that limit subsidiary indebtedness. We continually monitor our debt covenants to ensure we remain in compliance. We have not observed any current trends that would cause a breach of any debt covenants.

See "Debt, Term Loan Facility, Credit Facilities and Other Sources of Liquidity" and Note 10 of the "Notes to Consolidated Financial Statements" contained in Part II, Items 7 and 8, respectively, of our annual report on Form 10-K for the year ended December 31, 2025 for further discussion.

Shelf Registration

We maintain a shelf registration with the Securities and Exchange Commission to issue various types of securities, including common stock, preferred stock, debt securities, depository shares, stock purchase contracts, units and warrants. The shelf registration enables us to raise funds from the offering of any securities covered by the shelf registration as well as any combination thereof, subject to market conditions and our capital needs.

Commitments

As of September 30, 2026, we had commitments of $182.6 million to fund certain investments in private placement fixed maturity securities and $778.8 million to fund certain private equity partnerships. In addition, we had $11.1 million of commercial mortgage loan commitments.

With respect to our commitments and off-balance sheet arrangements, see the discussion under "Cash Requirements" in Part II, Item 7 of our annual report on Form 10-K for the year ended December 31, 2025. During the first nine months of 2026, there were no substantive changes in our commitments, contractual obligations, or other off-balance sheet arrangements other than the changes noted herein.

Transfers of Financial Assets

Our investment policy permits us to lend fixed maturity securities to unaffiliated financial institutions in short-term securities lending agreements, which increases our investment income with minimal risk. We account for all of our securities lending agreements and repurchase agreements as secured borrowings. As of September 30, 2026, we held $62.9 million of cash collateral from securities lending agreements. The average cash collateral balance during the first nine months of 2026 was $62.6 million, and the maximum amount outstanding at any month end was $70.3 million. As of September 30, 2026, we held $40.3 million of off-balance sheet securities lending agreements which were collateralized by securities that we were neither permitted to sell nor control. The average balance of these off-balance sheet transactions during the first nine months of 2026 was $38.4 million, and the maximum amount outstanding at any month end was $43.1 million.

To manage our cash position more efficiently, we may enter into securities repurchase agreements with unaffiliated financial institutions. We generally use securities repurchase agreements as a means to finance the purchase of invested assets or for short-term general business purposes until projected cash flows become available from our operations or existing investments. We had no securities repurchase agreements outstanding at September 30, 2026, nor did we utilize any securities repurchase

129

agreements during the first nine months of 2026. Our use of securities repurchase agreements and securities lending agreements can fluctuate during any given period and will depend on our liquidity position, the availability of long-term investments that meet our purchasing criteria, and our general business needs.

Certain of our U.S. insurance subsidiaries are members of regional FHLBs. As of September 30, 2026, we owned $50.4 million of FHLB common stock and had outstanding advances of $804.7 million from the regional FHLBs which were used for the purpose of investing in either short-term investments, matched fixed maturity securities, or matched commercial mortgage loans. As of September 30, 2026, we have additional borrowing capacity of approximately $552.3 million from the FHLBs.

See Note 4 of the "Notes to Consolidated Financial Statements" contained herein in Item 1 for further information.

Consolidated Cash Flows

(in millions of dollars)
	Nine Months Ended September 30
	2026		2025
Net Cash Provided by Operating Activities	$	1,405.8	$	329.8
Net Cash Provided (Used) by Investing Activities	(1,252.3)		771.4
Net Cash Used by Financing Activities	(31.8)		(936.1)
Net Change in Cash and Bank Deposits	$	121.7	$	165.1

Operating Cash Flows

Operating cash flows are primarily attributable to the receipt of premium and investment income, offset by payments of claims, commissions, expenses, and income taxes. Premium income growth is dependent not only on new sales, but on policy renewals and growth of existing business, renewal price increases, and persistency. Investment income growth is dependent on the growth in the underlying assets supporting our insurance liabilities and capital and on the earned yield. The level of commissions and operating expenses is attributable to the level of sales and the first year acquisition expenses associated with new business as well as the maintenance of existing business. The level of paid claims is affected partially by the growth and aging of the block of business and also by the general economy, as previously discussed in the operating results by segment.

The variance in the change in insurance liabilities to reconcile net income to net cash provided by operating activities as reported in our consolidated statements of cash flows for the first nine months of 2026 and 2025 was impacted by the reserve assumption updates that occurred in the third quarters of 2026 and 2025. Also included in operating cash flows for the first nine months of 2025 was $953.5 million of cash paid to the reinsurer in the 2025 Fortitude Re reinsurance transaction. See Note 14 of the "Notes to Consolidated Financial Statements" for additional information on the 2025 Fortitude Re reinsurance transaction and Note 7 of the "Notes to Consolidated Financial Statements" for additional information on the 2025 and 2026 reserve assumption updates.

Investing Cash Flows

Investing cash inflows consist primarily of the proceeds from the sales and maturities of investments. Investing cash outflows consist primarily of payments for purchases of investments. Our investment strategy is to match the cash flows and durations of our assets with the cash flows and durations of our liabilities to meet the funding requirements of our business. When market opportunities arise, we may sell selected securities and reinvest the proceeds to improve the yield and credit quality of our portfolio. We may at times also sell selected securities and reinvest the proceeds to improve the duration matching of our assets and liabilities and/or re-balance our portfolio. As a result, sales before maturity may vary from period to period. The sale and purchase of short-term investments is influenced by proceeds received from funding agreement advances, issuance of debt, our securities lending program, and by the amount of cash which is at times held in short-term investments to facilitate the availability of cash to fund the purchase of appropriate long-term investments, repay maturing debt, and/or to fund our capital deployment program.

During the first quarter of 2025, fixed maturity securities with a fair value of $151.6 million were sold in preparation for the 2025 Fortitude Re reinsurance transaction. Also during the first quarter of 2025, fixed maturity securities with a fair value of $81.8 million were sold related to the funding of an extraordinary dividend from a wholly owned insurance subsidiary to Unum Group.

130

See Note 4 of the "Notes to Consolidated Financial Statements" contained herein in Item 1 and "Investments" contained herein in this Item 2 for further information.

Financing Cash Flows

Financing cash flows consist primarily of borrowings and repayments of debt, dividends paid to stockholders, repurchases of common stock, and policyholders' account deposits and withdrawals.

The proceeds from policyholders' account deposits and payments for policyholders' account withdrawals increased for the first nine months of 2026 due primarily to an increase in funding agreement activity.

During the first quarter of 2026, we purchased and retired $7.7 million aggregate principal amount of our 6.250% junior subordinated debt securities due 2058, for which we paid $7.2 million in cash.

Cash used to repurchase shares of Unum Group's common stock during the first nine months of 2026 and 2025 was $807.2 million and $751.8 million, respectively. During the first nine months of 2026 and 2025, we paid dividends of $231.8 million and $228.9 million, respectively, to holders of Unum Group's common stock.

Also included in financing cash flows during the first nine months of 2026 and 2025 was $12.4 million and $17.4 million, respectively, of cash received related to the active life cohort volatility agreement with Commonwealth as a result of the Closed Block individual disability reinsurance transaction.

Ratings

A.M. Best Company (AM Best), Fitch Ratings (Fitch), Moody's Ratings (Moody's), and S&P Global Ratings (S&P) are among the third parties that assign issuer credit ratings to Unum Group and financial strength ratings to our insurance subsidiaries. Issuer credit ratings reflect an agency's opinion of the overall financial capacity of a company to meet its senior debt obligations. Financial strength ratings are specific to each individual insurance subsidiary and reflect each rating agency's view of the overall financial strength (capital levels, earnings, growth, investments, business mix, operating performance, and market position) of the insuring entity and its ability to meet its obligations to policyholders. Both the issuer credit ratings and financial strength ratings incorporate quantitative and qualitative analyses by rating agencies and are routinely reviewed and updated on an ongoing basis.

We maintain an ongoing dialogue with the four rating agencies that evaluate us in order to inform them of progress we are making regarding our strategic objectives and financial plans as well as other pertinent issues. A significant component of our communications involves our annual review meeting with each of the four agencies. We hold other meetings throughout the year regarding our business, including, but not limited to, quarterly updates.

Agency ratings are not directed toward the holders of our securities and are not recommendations to buy, sell, or hold our securities. Each rating is subject to revision or withdrawal at any time by the assigning rating organization, and each rating should be regarded as an independent assessment, not conditional on any other rating. Given the dynamic nature of the ratings process, changes by these or other rating agencies may or may not occur in the near term. We have ongoing dialogue with the rating agencies concerning our insurance risk profile, our financial flexibility, our operating performance, and the quality of our investment portfolios. The rating agencies provide specific criteria and, depending on our performance relative to the criteria, will determine future negative or positive rating agency actions.

We compete based in part on the financial strength ratings provided by rating agencies. A downgrade of our financial strength ratings can be expected to adversely affect us and could potentially, among other things, adversely affect our relationships with distributors of our products and services and retention of our sales force, negatively impact persistency and new sales, particularly large case group sales and individual sales, and generally adversely affect our ability to compete. A downgrade in the issuer credit rating assigned to Unum Group can be expected to adversely affect our cost of capital or our ability to raise additional capital.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are subject to various market risk exposures including interest rate risk and foreign exchange rate risk. With respect to our exposure to market risk, see the discussion under "Investments" in Item 2 of this Form 10-Q and in Part II, Item 7A of our annual report on Form 10-K for the year ended December 31, 2025. During the first nine months of 2026, there was no substantive change to our market risk or the management of this risk.

ITEM 4. CONTROLS AND PROCEDURES

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we have evaluated the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended, as of the end of the period covered by this report. We evaluated those controls based on the 2013 Internal Control - Integrated Framework from the Committee of Sponsoring Organizations of the Treadway Commission. Based on that evaluation, these officers concluded that our disclosure controls and procedures were effective as of September 30, 2026.

There have been no changes in our internal control over financial reporting, as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended, during the quarter ended September 30, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

For the avoidance of doubt, (x) any Permitted Public Fixed Income Securities included in the Transferred Assets pursuant to this Section 2.03(e) shall not constitute part of the Initial Portfolio and shall not be subject to the Asset Selection Protocol and (y) the inclusion of such Permitted Public Fixed Income Securities as a portion of the Transferred Assets, together with any Permitted Public Fixed Income Securities included in the Initial Portfolio, may not cause the Permitted Public Fixed Income Securities to exceed the limit set forth set forth under the “Portfolio Limits” of the Investment Guidelines.

Section 2.04Post-Closing Adjustments.

(a)Within 30 Business Days following the Closing Date, the Ceding Company shall prepare and deliver to the Reinsurer and, for informational purposes only, the Retrocessionaire, a Statement of Net Settlement as of the Effective Time, including reasonably detailed support thereof (the “Initial Statement of Net Settlement”), which shall set forth (i) the Updated Reference Base Deposit Balance determined in accordance with Section 2.03(b), the Adjusted Interest Maintenance Reserve and Initial Reinsurance Premium (but not the Effective Time Adjusted Statutory Reserves), the Ceding Commission, the Interim Period Cash Flows (using the Original Reference Base Deposit Balance) and the Total Net Settlement, prepared in the same format as the form of Statement of Net Settlement attached as Schedule II and (ii) the updated Fair Market Value of the Transferred Assets (including, for completeness, the cash and any Permitted Public Fixed Income Securities transferred on the Closing Date by the Ceding Company pursuant to Section 2.03(d)), individually and in the aggregate, and the updated Transaction IMR Amount as to such Transferred Assets, in each case, determined as of 4:00 p.m. (Eastern time) on the Business Day immediately prior to the Closing Date.

(b)During the 30 Business Days immediately following the Reinsurer’s receipt of the Initial Statement of Net Settlement (the “Review Period”), the Reinsurer and its Representatives shall be permitted to obtain and review the Ceding Company’s working papers and any working papers of the Ceding Company’s independent accountants relating to the preparation of the Initial Statement of Net Settlement, as well as all of the Books and Records and other relevant information relating to the performance or condition of the Business with respect to the period up to and including the Closing Date, and the Ceding Company shall make reasonably available the individuals in its or its Affiliates’ employ who are responsible for or knowledgeable about the information used in, or the preparation or calculation (as applicable) of, the Initial Statement of Net Settlement in order to respond to the inquiries of the Reinsurer; provided, however, that the Review Period shall be tolled pending reasonable satisfaction of the Reinsurer’s reasonable requests in the event that the Ceding Company does not

23

provide the Reinsurer with access to such working papers, Books and Records or other relevant information or access to such individuals within five Business Days of the Reinsurer’s request; providedfurther that the independent accountants of the Ceding Company shall not be obligated to make any working papers available to the Reinsurer or its Representatives unless and until the Reinsurer and such Representatives have signed customary confidentiality and hold harmless agreements relating to such access to working papers in form and substance reasonably acceptable to such independent accountants.

(c)If the Reinsurer (i) determines that one or more of the balances set forth on the Initial Statement of Net Settlement (x) reflects a mathematical error or (z) otherwise is or was prepared on a basis inconsistent with the applicable requirements of this Agreement (including, without limitation, the Fair Market Value Methodologies) or (ii) has any good faith objection to the valuation of any Transferred Asset set forth on the Initial Statement of Net Settlement, then the Reinsurer may, on or prior to the last day of the Review Period, deliver a notice to the Ceding Company and, for informational purposes only, the Retrocessionaire, setting forth, in reasonable detail, each disputed item or amount and the basis for the Reinsurer’s disagreement therewith (the “Notice of Disagreement”). The Notice of Disagreement shall set forth, with respect to each disputed item, the Reinsurer’s position as to the correct amount or computation that should have been included in the Initial Statement of Net Settlement. If the Reinsurer does not deliver a Notice of Disagreement to the Ceding Company by the end of the Review Period, the Initial Statement of Net Settlement shall become final and binding on the parties.

(d)During the 30 Business Days immediately following the delivery of a Notice of Disagreement, the Ceding Company and the Reinsurer shall seek in good faith to resolve any disagreement that they may have with respect to the matters specified in the Notice of Disagreement. If the Ceding Company and the Reinsurer reach agreement with respect to any such disagreements, the Ceding Company shall revise the Initial Statement of Net Settlement to reflect such agreement.

(e)If, at the end of such 30 Business Day period, the Ceding Company and the Reinsurer do not resolve all disagreements that they may have with respect to the matters specified in the Notice of Disagreement, then the Ceding Company and the Reinsurer shall submit all matters that remain in dispute with respect to the Notice of Disagreement (along with a copy of the Initial Statement of Net Settlement marked to indicate those line items that are in dispute) to (i) in the case of a dispute with respect to the valuation of the Transferred Assets (including the Fair Market Value of the Transferred Assets), the Independent Valuation Expert, to make a determination with respect to all such matters related to Fair Market Value that are in dispute and (ii) in the case of any other dispute, Deloitte or KPMG, or if Deloitte or KPMG is unwilling or unable to serve, an independent certified public accounting firm in the United States of international recognition mutually agreeable to the Ceding Company and the Reinsurer

24

and that is not the auditor or independent accounting firm of any of the parties or their Affiliates (the “Independent Accountant”), to make a determination with respect to all such other matters in dispute.

(f)The Ceding Company and the Reinsurer shall use commercially reasonable efforts to cause the Independent Valuation Expert or the Independent Accountant, as applicable, to render a determination within 30 days after the submission of such matters to the Independent Accountant or as soon as practicable thereafter. The Ceding Company, on the one hand, and the Reinsurer, on the other hand, shall promptly (and in any event within 10 Business Days) after the Independent Valuation Expert’s or the Independent Accountant’s, as applicable, engagement, each submit to the Independent Valuation Expert or the Independent Accountant, as applicable, their respective computations of the disputed items identified in the Notice of Disagreement and information, arguments and support for their respective positions, and shall concurrently deliver a copy of such materials to the other party and, for informational purposes only, the Retrocessionaire. Each of the Ceding Company and the Reinsurer shall then be given an opportunity to supplement the information, arguments and support included in its initial submission with one additional submission to respond to any arguments or positions taken by the other party in such other party’s initial submission to the Independent Valuation Expert or the Independent Accountant, as applicable, which supplemental information shall be submitted to the Independent Valuation Expert or the Independent Accountant, as applicable, with a copy thereof to the other party and, for informational purposes only, the Retrocessionaire, within 10 Business Days after the first date on which both the Ceding Company and the Reinsurer have submitted their respective initial submissions to the Independent Valuation Expert or the Independent Accountant, as applicable. The Independent Valuation Expert or Independent Accountant, as applicable, shall thereafter be permitted to request additional or clarifying information from the Ceding Company and the Reinsurer, and each of the Ceding Company and the Reinsurer shall cooperate and shall cause its Representatives to cooperate with such requests. The Independent Valuation Expert or the Independent Accountant, as applicable, shall determine, based solely on the materials so presented by the parties and upon information received in response to such requests for additional or clarifying information and not by independent review, only those issues referred to it that remain in dispute specifically set forth in the Notice of Disagreement and shall render a written report to the Ceding Company and the Reinsurer and, solely for informational purposes, the Retrocessionaire, in which the Independent Valuation Expert or the Independent Accountant, as applicable, shall, after considering all matters referred to it and set forth in the Notice of Disagreement, determine what adjustments, if any, should be made to the amounts and computations set forth in the Initial Statement of Net Settlement solely as to the disputed items referred to it. Such written report shall set forth, in reasonable detail, the determination of the Independent Valuation Expert or the Independent Accountant, as applicable, with respect to each of the disputed line items specified in the Notice of Disagreement and referred to it, and the revisions, if any, to be made to the Initial Statement of Net Settlement resulting therefrom, together with

25

supporting calculations. With respect to each disputed line item, such determination shall be made in accordance with (i) the terms of this Agreement and, if not in accordance with the position of either the Ceding Company or the Reinsurer, shall not be in excess of the higher, nor less than the lower, of the amounts advocated by the Reinsurer in the Notice of Disagreement or the Ceding Company in the Initial Statement of Net Settlement with respect to such disputed line item. For the avoidance of doubt, neither the Independent Valuation Expert nor the Independent Accountant shall review any line items or make any determination with respect to any matter other than those matters referred to it and set forth in the Notice of Disagreement that remain in dispute. Any final, written determination of the Independent Valuation Expert with respect to the Fair Market Value of the Transferred Assets, and any final, written determination of the Independent Accountant as to any other matters in the Notice of Disagreement, shall, absent fraud or manifest error, be conclusive and binding upon the Ceding Company and the Reinsurer, shall not be subject to review by a court or other tribunal and shall have the same force and effect as an arbitration award governed by the Federal Arbitration Act, 9 U.S.C. § 1 et seq. The “Final Statement of Net Settlement” means the Initial Statement of Net Settlement as made final and binding either pursuant to Section 2.04(c) or after it has been modified to reflect any revisions thereto made through the mutual agreement of the Reinsurer and the Ceding Company or through the determination of the Independent Valuation Expert or the Independent Accountant, as applicable, pursuant to this Section 2.04(f).

(g)The cost of each of the Independent Valuation Expert’s and the Independent Accountant’s review and determination shall be shared equally by the Ceding Company and the Reinsurer. During any review by the Independent Valuation Expert or the Independent Accountant, the Ceding Company and the Reinsurer shall each make available to the Independent Valuation Expert or the Independent Accountant, as applicable, such individuals and such information, books, records and work papers, as may be reasonably required by the Independent Valuation Expert or the Independent Accountant, as applicable, to fulfill its obligations under Section 2.04(f); provided, however, that the independent accountants of the Ceding Company or the Reinsurer shall not be obligated to make any working papers available to the Independent Valuation Expert or the Independent Accountant unless and until the Independent Valuation Expert or the Independent Accountant, as the case may be, has signed a customary confidentiality and hold harmless agreement relating to such access to working papers in form and substance reasonably acceptable to such independent accountants. In acting under this Agreement, each of the Independent Valuation Expert and the Independent Accountant shall be entitled to the privileges and immunities of an arbitrator. Notwithstanding anything to the contrary contained in this Agreement, the provisions of this Section 2.04 represent the sole and exclusive method for determining the Final Statement of Net Settlement.

(h)Following the determination of the Final Statement of Net Settlement, the Reinsurer shall prepare and deliver to the Ceding Company, and, for informational

26

purposes only, the Retrocessionaire, an updated version of Schedule K of the Coinsurance Agreement (Base Deposit Balance, Reference Recapture Amount and Reference Required Balance) which shall (x) set forth an updated calculation of the Base Deposit Balance, the Reference Recapture Amount and the Reference Required Balance, in each case based on the Updated Reference Base Deposit Balance calculated on a post-closing basis in accordance with Section 2.04(a), and (y) replace the version of Schedule K to the Coinsurance Agreement delivered in accordance with Section 2.03(c) above.

Section 2.05Post-Closing Payments.

(a)The following adjustments will be made with respect to the transactions contemplated by the Coinsurance Agreement based on the amounts set forth on the Final Statement of Net Settlement:

(i)if the Estimated Total Net Settlement Amount exceeds the Total Net Settlement Amount as reflected on the Final Statement of Net Settlement, the Reinsurer shall, within 10 Business Days of the determination thereof, transfer or cause to be transferred to the Ceding Company (which may be by transfer from the Trust Accounts to the extent permitted pursuant to the Coinsurance Agreement and Trust Agreements) an amount of cash equal to such excess, together with interest thereon from and including the date on which the Closing Date falls to but not including the date of such transfer computed at the Closing Interest Rate, by wire transfer of immediately available funds, to an account or accounts designated by the Ceding Company;

(ii)if the Total Net Settlement Amount as reflected on the Final Statement of Net Settlement exceeds the Estimated Total Net Settlement Amount, the Ceding Company shall, within 10 Business Days of the determination thereof, transfer to the Reinsurer an amount of cash equal to such excess, together with interest thereon from and including the date on which the Closing Date falls to but not including the date of such transfer computed at the Closing Interest Rate, by wire transfer of immediately available funds, to an account or accounts designated by the Reinsurer;

(iii)if the aggregate Fair Market Value of the Transferred Assets as reflected on the Final Statement of Net Settlement exceeds the aggregate Fair Market Value of the Transferred Assets as reflected on the Estimated Statement of Net Settlement, the Reinsurer shall, within 10 Business Days of the determination thereof, transfer or cause to be transferred to the Ceding Company (which may be by transfer from the Trust Accounts to the extent permitted pursuant to the Coinsurance Agreement and Trust Agreements) an amount of cash equal to such excess, together with interest thereon from and including the Closing Date to but not including the date of such transfer computed at the Closing Interest Rate, by wire transfer of immediately available funds; and

27

(iv)if the aggregate Fair Market Value of the Transferred Assets as reflected on the Estimated Statement of Net Settlement exceeds the aggregate Fair Market Value of the Transferred Assets as reflected on the Final Statement of Net Settlement, the Ceding Company shall, within 10 Business Days of the determination thereof, transfer to the Reinsurer an amount of cash equal to such excess, together with interest thereon from and including the Closing Date to but not including the date of such transfer computed at the Closing Interest Rate, by wire transfer of immediately available funds, to an account or accounts designated by the Reinsurer.

Section 2.06Accrued Income. From and after the Closing Date, the Ceding Company shall transfer to the respective Trust Accounts (as directed by the Reinsurer) any interest or distributions received by the Ceding Company or its Affiliates in respect of any Transferred Asset.

Prior to any party being entitled to invoke an actual or potential Burdensome Condition, such party shall take, or cause its Affiliates to take, as applicable, all reasonable steps to avoid the impediment, effect or condition giving rise to the actual or potential existence of a Burdensome Condition or sufficiently mitigate the negative impact thereof if such reasonable steps can be identified. For the avoidance of doubt, any reasonable steps identified for the mitigation of any potential Burdensome Condition shall not themselves constitute a Burdensome Condition hereunder, and shall not be taken into account in determining whether any action, restriction, condition, limitation or requirement constitutes a Burdensome Condition hereunder.

(d)Except as otherwise agreed by the parties, each of the Ceding Company and the Reinsurer shall cooperate and use their respective commercially reasonable efforts to obtain all consents, approvals and agreements of any third party (other than a Governmental Authority), necessary to effect the Closing, including as set forth on Section 3.04(b) of the Ceding Company Disclosure Schedule and Section 4.04(b) of the Reinsurer Disclosure Schedule.

In complying with its obligations under this Section 6.13, the Ceding Company shall, and shall cause its Affiliates to, apply levels of diligence and care that the Ceding Company and its Affiliates apply in following such practices, policies and procedures with respect to business retained and unreinsured. Upon the Reinsurer’s reasonable request, the Ceding Company shall, and shall cause its Affiliates to, provide to the Reinsurer reasonable access such that the Reinsurer may from time to time review such practices, policies and procedures, and any such rights, and the efficacy thereof.

Section 6.14Binder Agreement. The Reinsurer shall (a) provide written notice to the Ceding Company of any proposed modification, amendment, supplement, replacement, restatement or waiver of any or all of the Reinsurer’s or the Retrocessionaire’s rights under the Binder Agreement that would or would reasonably be expected to be adverse in any respect to the Ceding Company and (b) shall not, without the prior written consent of the Ceding Company (such consent not to be unreasonably withheld, conditioned or delayed), undertake any such modification, amendment, supplement, replacement, restatement or waiver. The Reinsurer shall comply in all material respects with all of the terms and conditions of, and its obligations under, the Binder Agreement. The Reinsurer shall promptly provide written notice to the Ceding Company if it intends to terminate the Binder Agreement and, to the extent reasonably practicable, will consult with the Ceding Company in good faith prior to giving the Retrocessionaire notice that the Reinsurer will elect to terminate the Binder Agreement in accordance with its terms; provided that, the Reinsurer shall not terminate the Binder Agreement pursuant to Article IV, Paragraph 3 thereof without the Ceding Company’s prior written consent. The Reinsurer and the Ceding Company, as a third-party beneficiary of the Binder Agreement, shall each use its respective reasonable best efforts, and shall cooperate fully with the other, to enforce their respective rights under the Binder Agreement against the Retrocessionaire.

Section 6.15Post-Closing Review. From the Closing Date through the Audit End Date, the Retrocessionaire shall have the right to conduct a special audit with respect to the Reinsured Policies, in accordance with Section 5.3(c) of the Coinsurance Agreement, of all data sourced from the administrative systems and databases of the Ceding Company and its affiliates utilized in the preparation of the experience studies

55

made available in files 1.1.7, 1.1.8 and 1.1.13 of the Data Room, the Seriatim File and the Specified Data. For the avoidance of doubt, such special audits shall not count towards the number of audits permitted per calendar year pursuant to Section 5.3 of the Coinsurance Agreement. From the Audit End Date to the six-month anniversary of the Audit End Date, if the Retrocessionaire intends to bring a claim against the Ceding Company under Section 9.02(a)(ii), it shall notify the Ceding Company as promptly as practicable after forming such intention. In addition to the requirements set forth in Article IX, such notice shall specify in reasonable detail the discrepancies identified during the audit conducted pursuant to this Section 6.15.

TERMINATION PRIOR TO CLOSING

Section 8.01Termination. This Agreement may be terminated, and the transactions contemplated hereby abandoned, at any time prior to the Closing:

(a)by mutual written consent of the Ceding Company and the Reinsurer;

(b)by the Ceding Company in writing if the Reinsurer shall (i) fail to perform in any material respect its agreements contained herein required to be performed by it prior to the date of such termination, or (ii) materially breaches any of its representations or warranties contained herein so as to cause a condition to Closing to be incapable of

58

satisfaction, which failure or breach is not cured within 20 Business Days after the Ceding Company has notified the Reinsurer in writing of its intent to terminate this Agreement pursuant to this Section 8.01(b);

(c)by the Reinsurer in writing if the Ceding Company shall (i) fail to perform in any material respect its agreements contained herein required to be performed by it prior to the date of such termination, or (ii) materially breaches any of its representations or warranties contained herein so as to cause a condition to Closing to be incapable of satisfaction, which failure or breach is not cured within 20 Business Days after the Reinsurer has notified the Ceding Company in writing of its intent to terminate this Agreement pursuant to this Section 8.01(c);

(d)by any of the Ceding Company or the Reinsurer if the Closing has not occurred on or before December 31, 2026 (the “End Date”); provided, however, that the right to terminate this Agreement pursuant to this Section 8.01(d) shall not be available to a party if the failure of the transactions contemplated by this Agreement and the Transaction Agreements to be consummated on or before the End Date was primarily due to the failure of such party to perform any of its obligations under this Agreement;

(e)by any of the Ceding Company or the Reinsurer in the event of the issuance of a final nonappealable Order restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement and the Transaction Agreements; provided that the party seeking to terminate this Agreement pursuant to this Section 8.01(e) shall have complied with its obligations pursuant to Section 6.05 and used its commercially reasonable efforts to remove such Order; provided, however, that the right to terminate this Agreement under this Section 8.01(e) shall not be available to a party if the issuance of such final, nonappealable Order was primarily due to the failure of such party to perform any of its obligations under this Agreement.

Section 8.02Effect of Termination. In the event of termination of this Agreement pursuant to Section 8.01 hereof, written notice of termination shall be given pursuant to the notice provisions herein, and this Agreement shall forthwith become null and void and there shall be no liability to any party hereto, except (a) that the provisions of this Section 8.02 and Article X shall remain in full force and effect, (b) any confidentiality obligations of the parties arising under this Agreement shall survive the termination of this Agreement and (c) with respect to any liabilities or damages incurred or suffered by a party to the extent such liabilities or damages were the result of Fraud or the willful and material breach by another party of any of its representations, warranties, covenants or other agreements set forth in this Agreement. For purposes of this Section 8.02, “willful and material breach” shall mean a material breach that is the consequence of an act undertaken by the breaching party with the knowledge (actual or constructive) that the taking of such act would, or would reasonably be expected to, cause a material breach of this Agreement.

ARTICLE IX.

INDEMNIFICATION

Section 9.01Survival.

(a)The representations and warranties of the Ceding Company and the Reinsurer contained in this Agreement shall survive the Closing solely for purposes of this Article IX and shall terminate and expire on the date that is 24 months following the Closing Date; provided that the Ceding Company Fundamental Representations and the Reinsurer Fundamental Representations shall survive indefinitely or until the latest date permitted by Applicable Law; provided, further that the Specified Representations shall terminate and expire on the date that is six months following the Audit End Date. Any claim for indemnification in respect of any representation or warranty that is not asserted by notice given as required herein prior to the expiration of the specified period of survival shall not be valid, and any right to indemnification is hereby irrevocably waived after the expiration of such period of survival. Any claim properly made for an Indemnifiable Loss in respect of such a breach asserted within such period of survival as herein provided will be timely made for purposes hereof.

(b)To the extent that it is to be performed after the Closing, each covenant in this Agreement shall, for purposes of this Article IX, survive and remain in effect in accordance with its terms plus a period of 24 months thereafter, after which no claim for indemnification with respect thereto may be brought hereunder. All covenants in this Agreement that by their terms are required to be fully performed at or prior to the Closing shall survive the Closing for a period of 24 months, after which no claim for indemnification with respect thereto may be brought hereunder. Any claim of breach in respect of any covenant that is not asserted by notice given as required herein prior to the expiration of the specified period of survival shall not be valid, and any right to recover for such breach is hereby irrevocably waived after the expiration of such period of survival. Any claim properly made in respect of such a breach asserted within such period of survival as herein provided will be timely made for purposes hereof.

Section 9.02Indemnification.

(a)From and after the Closing, and subject to the limitations set forth in this Article IX, the Ceding Company shall defend, indemnify and hold harmless the Reinsurer, the Retrocessionaire and their respective Affiliates (collectively, the “Reinsurer Indemnified Persons”) from and against any and all Indemnifiable Losses asserted against, imposed upon or incurred or suffered by any such Reinsurer Indemnified Person to the extent resulting from, relating to or in connection with:

(i)any breach or inaccuracy of any representation or warranty of the Ceding Company made in Article III of this Agreement (other than any Ceding

60

Company Fundamental Representation or the Specified Representations if subject to a claim by the Retrocessionaire or its Affiliates under (ii));

(ii)any breach or inaccuracy of the Specified Representations if subject to a claim by the Retrocessionaire or its Affiliates;

(iii)any breach or inaccuracy of any Ceding Company Fundamental Representation; and

(iv)any breach or non-fulfillment of any agreement or covenant of the Ceding Company under this Agreement.

(b)From and after the Closing, and subject to the limitations set forth in this Article IX, the Reinsurer shall indemnify and hold harmless the Ceding Company and its Affiliates (collectively, the “Ceding Company Indemnified Persons”) from and against any and all Indemnifiable Losses asserted against, imposed upon or incurred or suffered by any such Ceding Company Indemnified Person to the extent resulting from, relating to or in connection with:

(i)any breach or inaccuracy of any representation or warranty of the Reinsurer made in Article IV of this Agreement (other than any Reinsurer Fundamental Representation);

(ii)any breach or inaccuracy of any Reinsurer Fundamental Representation; or

(iii)any breach or non-fulfillment of any agreement or covenant of the Reinsurer under this Agreement.

Section 9.03Certain Limitations.

(a)Notwithstanding anything to the contrary contained herein, (i) the Ceding Company shall not be obligated to indemnify and hold harmless the Reinsurer Indemnified Persons under Section 9.02(a)(i) or Section 9.02(a)(ii) and (ii) the Reinsurer shall not be obligated to indemnify and hold harmless the Ceding Company Indemnified Persons under Section 9.02(b)(i), in each case, (A) with respect to any claim or series of related claims arising from the same or similar facts, unless such claim or series of claims involves Indemnifiable Losses of such Indemnitees in excess of $[***] (the “Threshold Amount”) and (B) unless and until the aggregate amount of all Indemnifiable Losses of such Indemnitees (1) under Section 9.02(a)(i) or Section 9.02(b)(i), as applicable, relating to claims or series of related claims that exceed the Threshold Amount exceeds $[***] for all such Indemnifiable Losses (the “General Deductible Amount”) or (2) under Section 9.02(a)(ii) relating to claims or series of related claims that exceed the Threshold Amount exceeds $[***] (the “Specified Representation Deductible Amount”), at which point such Indemnitor shall be liable to the relevant Indemnitees for the value of such Indemnitee’s claims under Section 9.02(a)(i), Section 9.02(a)(ii) or Section 9.02(b)(i), as the case may

61

be, that are in excess of the General Deductible Amount or the Specified Representation Deductible Amount, as applicable, subject to the limitations set forth in this Article IX.    

(b)The maximum aggregate liability of the Ceding Company for any all Indemnifiable Losses under (i) Section 9.02(a)(i) shall be $[***] (the “General Cap”) and (ii) Section 9.02(a)(ii) shall be $[***]. The maximum aggregate liability of the Reinsurer for any and all Indemnifiable Losses under Section 9.02(b)(i) shall be $[***]. For the purposes of this Agreement, the Specified Representation Deductible Amount and the $[***] cap applicable to claims under Section 9.02(a)(ii) shall only be applicable to Indemnifiable Losses of the Retrocessionaire and its Affiliates and not to those of the Reinsurer and its Affiliates, and any such Indemnifiable Losses of the Retrocessionaire and its Affiliates under Section 9.02(a)(ii) shall not count towards the General Deductible Amount or the General Cap.

(c)Any Indemnifiable Losses shall be net of any (i) amounts recovered by the Indemnitee for the Indemnifiable Losses for which such Indemnity Payment is made under (x) the Retrocession Agreement or any other Contract between the Reinsurer or its Affiliates, on the one hand, and the Retrocessionaire or its Affiliates, on the other hand, related to the transactions contemplated by this Agreement or (y) any other insurance policy, reinsurance agreement, warranty or indemnity or otherwise from any Person other than a party hereto or one of its Affiliates as reduced by the amount of any costs reasonably incurred by the Indemnitee in seeking such recovery, and the Indemnitee shall promptly reimburse the Indemnitor for any such amount that is received by it from any such other Person with respect to Indemnifiable Losses after any indemnification with respect thereto has actually been paid pursuant to this Agreement less any costs incurred in recovering such amount and (ii) amounts reserved for on the Final Statement of Net Settlement; provided that such reimbursement shall only be required to the extent the Indemnitee would otherwise retain an amount greater than the full amount of the Indemnifiable Losses incurred by the Indemnitee as a result of the underlying claim.

(d)Each Indemnitee shall use commercially reasonable efforts to mitigate all Indemnifiable Losses for which indemnification may be sought hereunder to the extent such mitigation is required by Applicable Law; provided that the cost and expense of such mitigation shall constitute Indemnifiable Losses hereunder.

(e)For purposes of determining any Indemnifiable Losses or other recovery for a breach of Specified Representations, the amount of Indemnifiable Losses resulting from data inaccuracies shall be determined on a net basis in the aggregate (but shall not be negative), taking into account both the damages and the benefits to the respective Indemnitee from such data inaccuracies. Notwithstanding the foregoing, for 45 days after the Ceding Company’s receipt of notice of a claim of breach of Specified Representations, the Ceding Company shall have the right to assert, with appropriate support, countervailing errors unrelated to the data errors underlying the Indemnitee’s

62

claim; provided that such assertion of countervailing errors shall be limited to those that were relevant to evaluation of the party seeking the indemnity.

(f)For the avoidance of doubt, limitations on recovery amounts or the period during which recovery is available, in each case as set forth in this Agreement, shall not be applied to any breach or non-fulfillment of any other agreement or covenant of the Ceding Company under any other Transaction Agreement, unless the same action, event, circumstance or occurrence would constitute a breach by the Ceding Company and its Affiliates of both this Agreement and the applicable Transaction Agreement.

(g)Notwithstanding anything to the contrary in this Agreement, in no event shall the Ceding Company be subject to, or liable for, duplicative Indemnifiable Losses hereunder (it being agreed that the Reinsurer and the Retrocessionaire may suffer or incur different Indemnifiable Losses arising from the same underlying set of facts or circumstances); provided that the foregoing shall not limit an Indemnitee’s ability to make a claim as to a breach of more than one representation, warranty, covenant or agreement arising from the same state of facts. For the avoidance of doubt, no Indemnitee shall be entitled to duplication of recovery with respect to Indemnifiable Losses arising under the same underlying subject matter. To the extent that an Indemnitee has received payment from an Indemnitor in respect of an Indemnifiable Loss pursuant to the provisions of any other Transaction Agreement, such Indemnitee shall not be entitled to such Indemnifiable Loss from the same Indemnitor under this Agreement, and no Indemnitee may obtain duplicative indemnification or other recovery from the same Indemnitor for Indemnifiable Losses under one or more provisions of this Agreement, on the one hand, and any other Transaction Agreement, on the other hand.

Section 9.04Definitions. As used in this Agreement:

(a)“Indemnitee” means any Person entitled to indemnification under this Agreement;

(b)“Indemnitor” means any Person required to provide indemnification under this Agreement;

(c)“Indemnifiable Losses” means any and all damages, losses, liabilities, obligations, costs, expenses (including reasonable and documented out-of-pocket attorneys’ fees and expenses), settlement payments, awards, judgments, fines, interest or penalties; provided, however, that Indemnifiable Losses shall not include any punitive, exemplary damages or damages based on diminution in value, other than such damages actually paid to a non-Affiliated Person (other than the Retrocessionaire or its Affiliates) in respect of a Third Party Claim or any diminution in value damages comprising reasonably foreseeable lost profits recoverable under the laws of the State of New York.

(d)“Indemnity Payment” means any amount of Indemnifiable Loss required to be paid pursuant to this Agreement; and

63

(e)“Third Party Claim” means any claim, action, suit, or proceeding made or brought by any Person that is not the Retrocessionaire or a party to this Agreement and is not an Affiliate of the Retrocessionaire or any party to this Agreement.

Section 9.05Procedures for Third Party Claims.

(a)If any Indemnitee receives written notice of assertion or commencement of any Third Party Claim against such Indemnitee in respect of which an Indemnitor may be obligated to provide indemnification under this Agreement, the Indemnitee shall give such Indemnitor reasonably prompt written notice (but in no event later than 30 days after becoming aware of such Third Party Claim) thereof and such notice shall include a reasonable description of the claim based on facts known at the time and any documents relating to the claim and an estimate of the Indemnifiable Losses and shall reference the specific sections of this Agreement that form the basis of such claim to the extent reasonably ascertainable; provided that no delay on the part of the Indemnitee in notifying any Indemnitor shall relieve the Indemnitor from any obligation hereunder unless (and then solely to the extent) the Indemnitor is actually prejudiced by such delay. Thereafter, the Indemnitee shall deliver to the Indemnitor, as promptly as practicable after the Indemnitee’s receipt thereof, copies of all notices and documents (including court papers) received by the Indemnitee relating to the Third Party Claim.

(b)The Indemnitor shall be entitled to participate in the defense of any Third Party Claim and, if it so chooses, to assume the defense thereof with counsel selected by the Indemnitor. Should the Indemnitor so elect to assume the defense of a Third Party Claim, the Indemnitor shall not as long as it conducts such defense be liable to the Indemnitee for legal expenses incurred by the Indemnitee in connection with the defense thereof subsequent to the Indemnitor notifying the Indemnitee in writing of its election to assume such defense. If the Indemnitor assumes such defense, the Indemnitee shall have the right to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the Indemnitor, it being understood that the Indemnitor shall control such defense. The Indemnitor shall be liable for the reasonable fees and expenses of counsel employed by the Indemnitee (i) for any period during which the Indemnitor has not assumed the defense thereof or (ii) if the Third Party Claim involves conflicts of interest for the Indemnitee and the Indemnitor (in the reasonable opinion of counsel to the Indemnitee) that would make representation by the same counsel inappropriate, in which event the Indemnitor shall be responsible for one firm to act as counsel for the Indemnitee. If the Indemnitor chooses to defend any Third Party Claim, the other party hereto shall cooperate in the defense thereof. Such cooperation shall include the retention and (upon the Indemnitor’s request) the provision to the Indemnitor of records and information that are relevant to such Third Party Claim, and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder; provided that such other party shall not be obligated to provide such records, information or access to the Indemnitor if doing so would violate Applicable Law or jeopardize the protection of an

64

attorney-client privilege. Whether or not the Indemnitor shall have assumed the defense of a Third Party Claim, the Indemnitee shall not admit any liability with respect to, or pay, settle, compromise or discharge, such Third Party Claim without the Indemnitor’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed). If the Indemnitor has assumed the defense of a Third Party Claim, the Indemnitor may only pay, settle, compromise or discharge a Third Party Claim with the Indemnitee’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed); provided that the Indemnitor may pay, settle, compromise or discharge such a Third Party Claim without the written consent of the Indemnitee if such settlement (A) includes a release of the Indemnitee from all liability in respect of such Third Party Claim, (B) does not subject the Indemnitee to any injunctive relief or other equitable remedy and provides solely for the payment of money, (C) does not include a statement or admission of fault, culpability or failure to act by or on behalf of the Indemnitee and (D) does not impose any financial or economic cost on the Indemnitee.

Section 9.06Direct Claims. In the event that any Indemnitee intends to bring a claim that does not involve a Third Party Claim for indemnity against any Indemnitor, the Indemnitee shall deliver written notice of such claim to the Indemnitor as promptly as practicable after forming such intention. Such notice shall specify in reasonable detail under the circumstances the facts giving rise to the claim and, to the extent practicable, an estimate of the amount of the potential Indemnifiable Loss. The Indemnitor will have a period of 30 days within which to respond in writing to any claim by an Indemnitee on account of an Indemnifiable Loss that does not result from a Third Party Claim. If the Indemnitor does not so respond within such thirty day period, the Indemnitor will be deemed to have rejected such claim, in which event the Indemnitee will be entitled to pursue such remedies as may be available to the Indemnitee.

Section 9.07Sole Remedy. The parties hereto acknowledge and agree that, except (a) in the case of Fraud, (b) as set forth in Section 10.14, (c) as expressly contemplated by Section 2.04 and (d) for any remedy expressly contemplated by any other Transaction Agreement with respect to a claim made under such Transaction Agreement (but subject to Section 9.03(f) above) their sole and exclusive remedy following the Closing, at law or equity, with respect to this Agreement shall be pursuant to the provisions set forth in this Article IX. In furtherance of the foregoing, each party hereby irrevocably waives, to the fullest extent permitted under Applicable Law, any and all rights, claims and causes of action whatsoever for any breach or non-fulfillment of any representation, warranty, covenant or agreement in this Agreement it may have against the other party arising under or based upon any Applicable Law, including rescission, except pursuant to the indemnification provisions set forth in this Article IX or in respect of any cause of action arising from Fraud, the rights of the parties pursuant to Section 2.04, the rights of the parties following the termination of this Agreement under Section 8.02 and the remedies of injunction and specific performance to the extent available under Section 10.14. For the avoidance of doubt, this Section 9.07 shall not apply to the parties’ rights to recover under the other Transaction Agreements.

65

Section 9.08Certain Other Matters.

(a)Upon making any Indemnity Payment, the relevant Indemnitor will, to the extent of such Indemnity Payment, be subrogated to all rights of the Indemnitee against any third Person in respect of the Indemnifiable Loss to which the Indemnity Payment related. Without limiting the generality or effect of any other provision hereof, each such Indemnitee and Indemnitor will duly execute upon request all instruments reasonably necessary to evidence and perfect the above-described subrogation rights.

(b)The right to indemnification, payment of Indemnifiable Losses, or other remedy based on representations, warranties, covenants, and obligations under this Agreement will not be affected by any investigation conducted with respect to, or any knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement, with respect to the accuracy or inaccuracy of or compliance with, any such representation, warranty, covenant, or obligation.

Section 9.09Materiality. For purposes of this Article IX, any breach or inaccuracy of any representation and warranty (other than as set forth in Section 3.17(a)) and the amount of any Indemnifiable Losses resulting therefrom shall be determined without giving effect to any exception or qualification in such representations and warranties relating to “Material Adverse Effect,” “Reinsurer Material Adverse Effect,” “material” or “materiality” in any such representations and warranties.

Any party may, by notice given in accordance with this Section 10.03 to the other parties, designate another address or person for receipt of Notices hereunder, provided that notice of such a change shall be effective upon receipt.

(b)Notwithstanding anything to the contrary herein, any party providing Notices to another party hereunder shall also provide such Notice concurrently to the Retrocessionaire as well, in accordance with the notice mechanics and at the address(es) specified in (a). No party has an affirmative obligation to provide any other Person, including the Retrocessionaire, with a copy of any Notice it receives hereunder.

Section 10.04Entire Agreement. This Agreement (including the exhibits and schedules hereto), the other Transaction Agreements and the Confidentiality Agreement constitute the entire agreement of the parties hereto with respect to the subject matter of the Transaction Agreements and supersede all prior agreements and undertakings, both written and oral between, among or on behalf of (a) the Ceding Company and its Affiliates and (b) the Reinsurer and its Affiliates, with respect to the subject matter of the Transaction Agreements.

Section 10.05Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced under any Applicable Law or as a matter of public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated by this Agreement is not affected in any manner materially adverse to any party hereto. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in a mutually acceptable manner in order that the transactions

69

contemplated by this Agreement be consummated as originally contemplated to the greatest extent possible. If any provision of this Agreement is interpreted by a court of competent jurisdiction to be so broad as to be unenforceable, that provision shall be interpreted to be only so broad as is enforceable.

Section 10.06Assignment. This Agreement may not be assigned, in whole or in part, by operation of law or otherwise without the prior written consent of each of the parties hereto. Any attempted assignment in violation of this Section 10.06 shall be void. This Agreement shall be binding upon, shall inure to the benefit of, and shall be enforceable by the parties hereto and their successors and permitted assigns.

Section 10.07Waivers and Amendments. No provision of this Agreement may be amended, supplemented or modified except by a written instrument signed by all of the parties hereto. No provision of this Agreement may be waived except by a written instrument signed by the party against whom the waiver is to be effective. No waiver of any breach of this Agreement shall be held to constitute a waiver of any other or subsequent breach. No failure or delay by any party hereto in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by Applicable Law.

Section 10.08Disclosure Schedules. Matters reflected in any section or subsection of the Ceding Company Disclosure Schedule or the Reinsurer Disclosure Schedule are not necessarily limited to matters required by this Agreement to be so reflected. Such additional matters are set forth for informational purposes and do not necessarily include other matters of a similar nature. No reference to or disclosure of any item or other matter in any section or subsection of the Ceding Company Disclosure Schedule or the Reinsurer Disclosure Schedule shall be construed as an admission or indication that such item or other matter is material or that such item or other matter is required to be referred to or disclosed in this Agreement, the Ceding Company Disclosure Schedule or the Reinsurer Disclosure Schedule. Without limiting the foregoing, no such reference to or disclosure of a possible breach or violation of any Contract, Applicable Law or Governmental Order shall be construed as an admission or indication that breach or violation exists or has actually occurred.

Section 10.09Governing Law; Waiver of Jury Trial.

(a)THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO SUCH STATE’S PRINCIPLES OF CONFLICT OF LAW THAT COULD COMPEL THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION.

70

(b)Other than (i) with respect to any dispute or controversy governed by the terms of Section 2.04 or (ii) any suit for specific performance with respect to Section 10.14, if either the Ceding Company or the Reinsurer has given written notification of a dispute relating to this Agreement and remedy sought to the other party, then within 15 Business Days after receipt of such notification both parties must designate an officer of their respective companies to attempt to resolve the dispute. The officers will meet at a mutually agreeable location as soon as possible and as often as reasonably necessary in order to gather and furnish the other with all appropriate and relevant information concerning the dispute. The officers will discuss the problem and will negotiate in good faith without the necessity of litigation or any formal arbitration proceedings. During the negotiation process, all reasonable requests related to the dispute made by one officer to the other for information will be honored. The specific format for such discussions will be decided by the designated officers. All discussions and negotiations shall be for settlement purposes only, deemed confidential and not admissible in any legal proceeding in the event the dispute remains unresolved and is resolved through such proceedings. If these officers are unable to resolve the dispute within 30 days of their first meeting, the parties may proceed as set out in (c) below, unless the parties mutually agree in writing to extend the negotiation period for an additional 30 days.

(c)Each of the parties (i) irrevocably and unconditionally agrees and consents that any judicial action may be brought in the courts of the State of New York and the federal courts of the United States of America located in New York; (ii) waives, to the fullest extent they may effectively do so, any objection, including any objection to the laying of venue or based on the grounds of forum non conveniens or any right of objection to jurisdiction on account of their place of incorporation or domicile, which they may now or hereafter have to the bringing of any such action or proceeding in any New York court; and (iii) irrevocably consents to service of process in the manner provided for notices in Section 10.03 or in any other manner permitted by Applicable Law. THE CEDING COMPANY AND THE REINSURER WAIVE, TO THE GREATEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY.

(d)The Reinsurer hereby designates the Superintendent of the Maine Bureau of Insurance as its true and lawful attorney upon whom may be served any lawful process in any action, suit or proceeding instituted by or on behalf of the Ceding Company. A copy of any such process shall be delivered (i) to Commissioner of the New Jersey Department of Banking and Insurance and (ii) to the Reinsurer in accordance with Section 10.03.

(e)This Section 10.09 is not intended to conflict with or override Section 2.04.

(b)Notwithstanding anything to the contrary contained herein or in the other Transaction Agreements, the Ceding Company Disclosure Schedule or any of the Schedules or Exhibits hereto or thereto, the Reinsurer acknowledges and agrees that neither the Ceding Company nor any of its Affiliates, nor any Representative of any of

72

them, makes or has made, and the Reinsurer has not relied on, any inducement, promise, representation or warranty, whether oral or written, express or implied, other than as expressly set forth in Article III. Without limiting the generality of the foregoing, other than as expressly set forth in Article III, no Person has made any representation or warranty to the Reinsurer with respect to any information, documents or material made available to the Reinsurer, its Affiliates or their respective Representatives with respect to the Ceding Company, the Business or the Reinsured Policies in any “data rooms,” information memoranda, management presentations, functional “break-out” discussions or in any other form or forum in connection with the transactions contemplated by this Agreement, including any estimation, valuation, appraisal, projection or forecast with respect to the Business. With respect to any such estimation, valuation, appraisal, projection or forecast delivered by or on behalf of the Ceding Company, the Reinsurer acknowledges that: (A) there are uncertainties inherent in attempting to make such estimations, valuations, appraisals, projections and forecasts; (B) such estimations, valuations, appraisals, projections and forecasts are not and shall not be deemed to be representations or warranties of the Ceding Company or any of its Affiliates and (C) it shall have no claim against any Person with respect to any such valuation, appraisal, projection or forecast.

Section 10.12Third Party Beneficiaries.

(a)The Parties hereby agree that the Reinsurer and the Retrocessionaire will enter into the Retrocession Agreement at Closing and the Retrocessionaire is an express third party beneficiary, solely with respect to the rights of the Reinsurer to the extent relating to the Retrocessionaire’s rights and obligations with respect to the Reinsured Policies and its rights and obligations under the Retrocession Agreement, to Article I (Definitions), Article II (Closing; Closing Transfers),Article III (Representations and Warranties of the Ceding Company), Article VI (Covenants), Section 7.01 (Conditions to Obligations of Each Party), Section 7.02 (Conditions to Obligations of the Ceding Company),Article VIII (Termination Prior to Closing), Article IX (Indemnification) and Article X (General Provisions) of this Agreement and any definitions used therein and any other provision of this Agreement to the extent relating to the Reinsured Liabilities or the Retrocessionaire’s rights and obligations under the Reinsured Policies or under the Retrocession Agreement (the “Specified Provisions”), unless the Retrocessionaire fails to enter into the Retrocession Agreement in breach of its obligations under the Binder

73

Agreement. In its capacity as a third-party beneficiary, the Retrocessionaire may exercise the rights of the Reinsurer under Section 6.12(c) and Section 6.12(d). If the Reinsurer is permitted or required pursuant to the Specified Provisions to make or give any consent or waiver relating to the requests, actions or inactions of Ceding Company, then the Retrocessionaire’s consent shall be required for such consent or waiver (such consent not to be unreasonably withheld, conditioned or delayed), unless the Retrocessionaire fails to enter into the Retrocession Agreement in breach of its obligations under the Binder Agreement. For the avoidance of doubt, nothing in this (a) shall be construed to preclude the Retrocessionaire’s right to dispute whether the applicable closing conditions set forth in Article VII or in the Binder Agreement have been satisfied.

(b)Reinsurer hereby covenants and agrees not to modify, amend, supplement, replace or restate, or waive any rights under the Specified Provisions in a manner that would reasonably be expected to adversely affect the Retrocessionaire in any non-de-minimis respect, without the prior written consent of the Retrocessionaire (not to be unreasonably withheld, conditioned or delayed). The Ceding Company hereby covenants and agrees not to amend the Specified Provisions in a manner that would reasonably be expected to adversely affect the Retrocessionaire in any non-de-minimis respect, without the prior written consent of the Retrocessionaire (not to be unreasonably withheld, conditioned or delayed).

(c)Other than as set forth in this Section 10.12 and the rights granted to the Ceding Company Indemnified Persons and the Reinsurer Indemnified Persons under Article IX, nothing in this Agreement is intended or shall be construed to give any Person, other than the parties hereto, their successors and permitted assigns, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein.

Section 10.13Execution in Counterparts. This Agreement may be executed by the parties hereto in separate counterparts, each of which when so executed and delivered shall be an original, but all such counterparts shall together constitute one and the same instrument. Delivery of an executed counterpart of a signature page to any Transaction Agreement by facsimile or other means of electronic transmission utilizing reasonable image scan technology shall be as effective as delivery of a manually executed counterpart of any such Agreement.

Section 10.14Equitable Remedies. The parties hereto agree that irreparable damage may occur and that the parties may not have an adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and that money damages or other legal remedies may not be an adequate remedy for any such failure to perform or breach. It is accordingly agreed that, without the necessity of posting bond or other undertaking, the parties hereto shall be entitled to seek an injunction or injunctions to prevent breaches of

74

this Agreement and to seek to enforce specifically the terms and provisions of this Agreement in accordance with this Agreement, this being in addition (subject to the terms of this Agreement) to any other remedy to which such party is entitled at law or in equity. The parties further agree that (a) by seeking any remedy provided for in this Section 10.14, a party shall not in any respect waive its right to seek any other form of relief that may be available to such party under this Agreement and (b) nothing contained in this Section 10.14 shall require any party to institute any action for (or limit such party’s right to institute any action for) specific performance under this Section 10.14 before exercising any other right under this Agreement.

Note 2 - Accounting Developments

Accounting Updates Adopted in 2025:

ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures

The amendments in this update required greater disaggregation of income tax disclosures related to the income tax rate reconciliation and income taxes paid. Specifically, the guidance required additional information that met a quantitative threshold in specified categories with respect to the reconciliation of the effective tax rate to the statutory tax rate for federal, state, and foreign income taxes. The specified categories were the following: state and local income taxes, foreign tax effects, effect of cross-border tax laws, enactment of new tax laws, nontaxable or nondeductible items, tax credits, changes in valuation allowances, and changes in unrecognized tax benefits. The quantitative threshold for each category is five percent of the amount computed by multiplying income (or loss) from continuing operations before income taxes by the statutory federal income tax rate. In addition, the amendments required additional information pertaining to income taxes paid, net of refunds, to be disaggregated by federal, state and foreign jurisdictions, and further disaggregated for specific jurisdictions to the extent the related amounts exceeded a quantitative threshold of five percent of total income taxes paid. The amendments also required disclosures of income (or loss) before income tax expense (or benefit) as domestic or foreign for each annual reporting period.

The amendments eliminated the historic requirement to disclose information regarding unrecognized tax benefits having a reasonable possibility of significantly increasing or decreasing in the twelve months following the reporting date, as well as the requirement to disclose the cumulative temporary differences when a deferred tax liability was not recognized due to certain exceptions under ASC 740.

The amendments in this update were applied retrospectively for the annual period ended December 31, 2025. The adoption of this update modified our disclosures, but did not have an impact on our financial position or results of operations.

Accounting Updates Outstanding:

ASU 2024-03, Disaggregation of Income Statement Expenses: Income Statement - Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses and related amendment

The amendments in this update require the disclosure of disaggregation of certain income statement expense line items. Specifically, the guidance requires the disclosure of additional information related to certain expenses, including employee compensation, depreciation and amortization, and certain other expenses included in each income statement line item. The amendments also require the disclosure of both the total amount of selling expenses and a definition of selling expenses.

We will adopt this update effective for the annual period beginning January 1, 2027, and interim periods beginning January 1, 2028. The adoption of this update is permitted on a prospective basis or a retrospective basis. The adoption of this update will expand our disclosures but will not have an impact on our financial position or results of operations.

ASU 2025-06, Targeted Improvements to the Accounting for Internal-Use Software: Intangibles - Goodwill and Other Internal-Use Software (Subtopic 350-40)

The amendments in this update modernize the recognition framework for the capitalization of internal-use software and remove all references to software development project stages. The guidance requires software development costs to be capitalized when both of the following criteria are met: (i) management has authorized and committed to funding the project, and (ii) it is probable that the project will be completed and the software will be used to perform its intended function. Additionally, the update aligns disclosure requirements for capitalized software costs with those under ASC 360-10, Property, Plant, and Equipment.

We will adopt this update effective for the interim and annual periods beginning January 1, 2028. The adoption of this update is permitted on a prospective, retrospective, or modified retrospective basis. We are currently evaluating the impact the adoption of this update will have on our financial position, results of operations, and disclosures.

Fair Values of Financial Instruments

9 Months Ended

Fair Value Disclosures [Abstract]

Fair Values of Financial Instruments

Fair Value of Financial Instruments

Fair Value Measurements for Financial Instruments Carried at Fair Value

We report fixed maturity securities, which are classified as available-for-sale securities, derivative financial instruments, and unrestricted equity securities at fair value in our consolidated balance sheets. We report our investments in private equity partnerships at our share of the partnerships' net asset value (NAV) per share or its equivalent as a practical expedient for fair value.

The degree of judgment utilized in measuring the fair value of financial instruments generally correlates to the level of pricing observability. Financial instruments with readily available active quoted prices or for which fair value can be measured from actively quoted prices in active markets generally have more pricing observability and less judgment utilized in measuring fair value. An active market for a financial instrument is a market in which transactions for an asset or a similar asset occur with sufficient frequency and volume to provide pricing information on an ongoing basis. A quoted price in an active market provides the most reliable evidence of fair value and should be used to measure fair value whenever available. Conversely, financial instruments rarely traded or not quoted have less observability and are measured at fair value using valuation techniques that require more judgment. Pricing observability is generally impacted by a number of factors, including the type of financial instrument, whether the financial instrument is new to the market and not yet established, the characteristics specific to the transaction, and overall market conditions.

We classify financial instruments in accordance with a fair value hierarchy consisting of three levels based on the observability of valuation inputs:

•Level 1 - the highest category of the fair value hierarchy classification wherein inputs are unadjusted and represent quoted prices in active markets for identical assets or liabilities at the measurement date.

•Level 2 - valued using inputs (other than prices included in Level 1) that are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument's anticipated life.

•Level 3 - the lowest category of the fair value hierarchy and reflects the judgment of management regarding what market participants would use in pricing assets or liabilities at the measurement date. Financial assets and liabilities categorized as Level 3 are generally those that are valued using unobservable inputs to extrapolate an estimated fair value.

Valuation Methodologies of Financial Instruments Measured at Fair Value

Valuation techniques used for assets and liabilities accounted for at fair value are generally categorized into three types. The market approach uses prices and other relevant information from market transactions involving identical or comparable assets or liabilities. The income approach converts future amounts, such as cash flows or earnings, to a single present amount, or a discounted amount. The cost approach is based upon the amount that currently would be required to replace the service capacity of an asset, or the current replacement cost.

We use valuation techniques that are appropriate in the circumstances and for which sufficient data are available that can be obtained without undue cost and effort. In some cases, a single valuation technique will be appropriate (for example, when valuing an asset or liability using quoted prices in an active market for identical assets or liabilities). In other cases, multiple valuation techniques will be appropriate. If we use multiple valuation techniques to measure fair value, we evaluate and weigh the results, as appropriate, considering the reasonableness of the range indicated by those results. A fair value measurement is the point within that range that is most representative of fair value in the circumstances.

The selection of the valuation method(s) to apply considers the definition of an exit price and depends on the nature of the asset or liability being valued. For assets and liabilities accounted for at fair value, we generally use valuation techniques consistent with the market approach, and to a lesser extent, the income approach. We believe the market approach provides more observable data than the income approach, considering the type of investments we hold. Our fair value measurements could differ significantly based on the valuation technique and available inputs. When using a pricing service, we obtain the vendor's pricing documentation to ensure we understand their methodologies. We periodically review and approve the selection of our pricing vendors to ensure we are in agreement with their current methodologies. When markets are less active, brokers may rely more on models with inputs based on the information available only to the broker. Our internal investment management professionals, which include portfolio managers and analysts, monitor securities priced by brokers and evaluate their prices for reasonableness based on benchmarking to available primary and secondary market information. In weighing a broker quote as an input to fair value, we place less reliance on quotes that do not reflect the result of market transactions. We also consider the nature of the quote, particularly whether it is a bid or market quote. If prices in an inactive market do not reflect current prices for the same or similar assets, adjustments may be necessary to arrive at fair value. When relevant market data is unavailable, which may be the case during periods of market uncertainty, the income approach can, in suitable circumstances, provide a more appropriate fair value. During 2026, we have applied valuation approaches and techniques on a consistent basis to similar assets and liabilities and consistent with those approaches and techniques used at year end 2025.

Fixed Maturity and Equity Securities

We use observable and unobservable inputs in measuring the fair value of our fixed maturity and equity securities. For securities categorized as Level 1, fair values equal active Trade Reporting and Compliance Engine (TRACE) pricing or unadjusted market maker prices. For securities categorized as Level 2 or Level 3, inputs that may be used in valuing each class of securities at any given time period are disclosed below. Actual inputs used to determine fair values will vary for each reporting period depending on the availability of inputs which may, at times, be affected by the lack of market liquidity.

The management of our investment portfolio includes establishing pricing policy and reviewing the reasonableness of sources and inputs used in developing pricing. We review all prices that vary between multiple pricing vendors by a threshold that is outside a normal market range for the asset type.  In the event we receive a vendor's market price that does not appear reasonable based on our market analysis, we may challenge the price and request further information about the assumptions and methodologies used by the vendor to price the security. We may change the selected price based on a better data source such as an actual trade. We also review all prices that did not change from the prior month to ensure that these prices are within our expectations. The overall valuation process for determining fair values may include adjustments to valuations obtained from

our pricing sources when they do not represent a valid exit price. These adjustments may be made when, in our judgment and considering our knowledge of the financial conditions and industry in which the issuer operates, certain features of the financial instrument require that an adjustment be made to the value originally obtained from our pricing sources. These features may include the complexity of the financial instrument, the market in which the financial instrument is traded, counterparty credit risk, credit structure, concentration, or liquidity. Additionally, an adjustment to the price derived from a model typically reflects our judgment of the inputs that other participants in the market for the financial instrument being measured at fair value would consider in pricing that same financial instrument. In the event an asset is sold, we test the validity of the fair value determined by our valuation techniques by comparing the selling price to the fair value determined for the asset in the immediately preceding month end reporting period.

Certain of our investments do not have readily determinable market prices and/or observable inputs or may at times be affected by the lack of market liquidity. For these securities, we use internally prepared valuations, including valuations based on estimates of future profitability, to estimate the fair value. Additionally, we may obtain prices from independent third-party brokers to aid in establishing valuations for certain of these securities. Key assumptions used by us to determine fair value for these securities include risk free interest rates, risk premiums, performance of underlying collateral (if any), and other factors involving significant assumptions which may or may not reflect those of an active market.

The parameters and inputs used to validate a price on a security may be adjusted for assumptions about risk and current market conditions on a quarter to quarter basis, as certain features may be more significant drivers of valuation at the time of pricing. Changes to inputs in valuations are not changes to valuation methodologies; rather, the inputs are modified to reflect direct or indirect impacts on asset classes from changes in market conditions.

At September 30, 2026, approximately 24.4 percent of our fixed maturity securities were valued using active trades from TRACE pricing or market maker prices for which there was current market activity in that specific security (comparable to receiving one binding quote).  The prices obtained were not adjusted, and the assets were classified as Level 1.

The remaining 75.6 percent of our fixed maturity securities were valued based on non-binding quotes or other observable and unobservable inputs, as discussed below:

•56.0 percent of our fixed maturity securities were valued based on prices from pricing services that generally use observable inputs such as prices for securities or comparable securities in active markets in their valuation techniques. These assets were classified as Level 2. 

•17.0 percent of our fixed maturity securities were valued based on one or more non-binding broker quotes, if validated by observable market data. When only one price is available, it is used if observable inputs and analysis confirms that it is appropriate. These assets, for which we were able to validate the price using other observable market data, were classified as Level 2.

•2.6 percent of our fixed maturity securities were valued based on prices of comparable securities, internal models, or pricing services or other non-binding quotes with no other observable market data. These assets were classified as either Level 2 or Level 3, with the categorization dependent on whether there was other observable market data.

Derivatives

Fair values for derivatives other than embedded derivatives in modified coinsurance arrangements are based on market quotes or pricing models and represent the net amount of cash we would have paid or received if the contracts had been settled or closed as of the last day of the period. Credit risk related to the counterparty and the Company is considered in determining the fair values of these derivatives. However, since we have collateralization agreements in place with each counterparty which limits our exposure, any credit risk is immaterial. Therefore, we determined that no adjustments for credit risk were required as of September 30, 2026 or December 31, 2025. Fair values for our embedded derivative in a modified coinsurance arrangement are estimated using internal pricing models and represent the hypothetical value of the duration mismatch of assets and liabilities, interest rate risk, and third party credit risk embedded in the modified coinsurance arrangement. We consider transactions in inactive markets to be less representative of fair value. We use all available observable inputs when measuring fair value, but when significant unobservable inputs are used, we classify these assets or liabilities as Level 3.

Private Equity Partnerships

Our private equity partnerships represent funds that are primarily invested in private credit, private equity, and real assets, as described below. Distributions received from the funds arise from income generated by the underlying investments as well as the liquidation of the underlying investments. There is generally not a public market for these investments.

The following tables present additional information about our private equity partnerships, including commitments for additional investments which may or may not be funded.

(a)Private Credit - The limited partnerships described in this category employ various investment strategies, generally providing direct lending or other forms of debt financing including first-lien, second-lien, mezzanine, and subordinated loans. The limited partnerships have credit exposure to corporates, physical assets, and/or financial assets within a variety of industries (including manufacturing, healthcare, energy, business services, technology, materials, and retail) in North America and, to a lesser extent, outside of North America.  As of September 30, 2026, the estimated remaining life of the investments that do not allow for redemptions is approximately 71 percent in the next 3 years, 4 percent during the period from 3 to 5 years, and 25 percent during the period from 5 to 10 years.

(b)Private Equity - The limited partnerships described in this category employ various strategies generally investing in controlling or minority control equity positions directly in companies and/or assets across various industries (including manufacturing, healthcare, energy, business services, technology, materials, and retail), primarily in private markets within North America and, to a lesser extent, outside of North America.  As of September 30, 2026, the estimated remaining life of the investments that do not allow for redemptions is approximately 37 percent in the next 3 years, 10 percent during the period from 3 to 5 years, 51 percent during the period from 5 to 10 years, and 2 percent during the period from 10 to 15 years.

(c)Real Assets - The limited partnerships described in this category employ various strategies, which include investing in the equity and/or debt financing of physical assets, including infrastructure (energy, power, water/wastewater, communications), transportation (including airports, ports, toll roads, aircraft, railcars) and real estate in North America, Europe, South America, and Asia.  As of September 30, 2026, the estimated remaining life of the investments that do not allow for redemptions is approximately 37 percent in the next 3 years, 22 percent during the period from 3 to 5 years, and 41 percent during the period from 5 to 10 years.

We record changes in our share of NAV of the partnerships in net investment income. We receive financial information related to our investments in partnerships and generally record investment income on a one-quarter lag in accordance with our accounting policy. Our partnerships are subject to transfer restrictions which extend over the life of the investment. There are no circumstances in which the transfer restrictions would lapse.

Realized and unrealized investment gains and losses presented in the preceding tables represent gains and losses only for the time during which the applicable financial instruments were classified as Level 3. The transfers between levels resulted primarily from a change in observability of three inputs used to determine fair values of the securities transferred: (1) transactional data for new issuance and secondary trades, (2) broker/dealer quotes and pricing, primarily related to changes in the level of activity in the market and whether the market was considered orderly, and (3) comparable bond metrics from which to perform an analysis. For fair value measurements of financial instruments that were transferred either into or out of Level 3, we reflect the transfers using the fair value at the beginning of the period. We believe this allows for greater transparency, as all changes in fair value that arise during the reporting period of the transfer are disclosed as a component of our Level 3 reconciliation.

The table below provides quantitative information regarding the significant unobservable inputs used in Level 3 fair value measurements derived from internal models. Unobservable inputs for fixed maturity securities are weighted by the fair value of the securities. Certain securities classified as Level 3 are excluded from the table below due to limitations in our ability to obtain the underlying inputs used by external pricing sources.

(a)Represents a decision to price based on par value, cost, owner's equity, or the price of the most recent capital funding round when limited data is available

(b)Represents various actuarial assumptions required to derive the liability cash flows. Fair value of embedded derivative is most often driven by the change in the weighted average credit spread to the swap curve for the assets backing the hypothetical loan

Other than market convention, the impact of isolated decreases in unobservable inputs will result in a higher estimated fair value, whereas isolated increases in unobservable inputs will result in a lower estimated fair value. The unobservable input for market convention is not sensitive to input movements. The projected liability cash flows used in the fair value measurement of our Level 3 embedded derivative are based on expected claim payments. If claim payments increase, the projected liability cash flows will increase, resulting in a decrease in the fair value of the embedded derivative. Decreases in projected liability cash flows will result in an increase in the fair value of the embedded derivative.

Fair Value Measurements for Financial Instruments Not Carried at Fair Value

The methods and assumptions used to estimate fair values of financial instruments not carried at fair value are discussed as follows:

Mortgage Loans: Fair value of newly originated, seasoned performing, or sub-performing but likely to continue cash flowing loans are calculated using a discounted cash flow analysis. Loans’ cash flows are modeled and appropriately discounted by a rate based on current yields and credit spreads. For sub and non-performing loans where there is some probability the loan will not continue to pay, a price based approach would be used to estimate the loan’s value in the open market utilizing current transaction information from similar loans.

Policy Loans: Fair values for policy loans, net of reinsurance ceded, are estimated using discounted cash flow analyses and interest rates currently being offered to policyholders with similar policies. Carrying amounts for ceded policy loans, which equal $3,216.4 million and $3,353.8 million as of September 30, 2026 and December 31, 2025, respectively, approximate fair value and are reported on a gross basis in our consolidated balance sheets. A change in interest rates for ceded policy loans will not impact our financial position because the benefits and risks are fully ceded to reinsuring counterparties.

Miscellaneous Long-term Investments: Our shares of Federal Home Loan Bank (FHLB) common stock are carried at cost, which approximates fair value.

Funding Agreements: Funding agreements included in policyholders' account balances represent cash advances used for the purpose of investing in either short-term investments, matched fixed maturity securities, or matched commercial mortgage loans. Carrying amounts approximate fair value.

Long-term Debt: Fair values for long-term debt are obtained from independent pricing services or discounted cash flow analyses based on current incremental borrowing rates for similar types of borrowing arrangements.

Other Liabilities: Funding agreements that represent cash advances used for the purpose of investing in either short-term investments, matched fixed maturity securities, or matched commercial mortgage loans. Unfunded equity commitments represent amounts that we have committed to fund investment partnerships. These commitments are legally binding, subject to the partnerships meeting specified conditions. Carrying amounts approximate fair value.

The following tables present the carrying amounts and estimated fair values of our financial instruments not measured at fair value and indicates the level in the fair value hierarchy of the estimated fair value measurement based on the observability of the inputs used.

The carrying values of financial instruments such as short-term investments, cash and bank deposits, accounts and premiums receivable, accrued investment income, securities lending agreements, and short-term debt approximate fair value due to the short-term nature of the instruments. As such, these financial instruments are not included in the above chart.

Fair values for insurance contracts other than investment contracts are not required to be disclosed. However, the fair values of liabilities under all insurance contracts are taken into consideration in our overall management of interest rate risk, which seeks to minimize exposure to changing interest rates through the matching of investment maturities with amounts due under insurance contracts.

1Allowance for Credit Losses

The following chart depicts an analysis of our fixed maturity security portfolio between investment-grade and below-investment-grade categories as of September 30, 2026.

					Gross Unrealized Loss
	Fair Value		Gross Unrealized Gain		Amount		Percent of Total Gross Unrealized Loss
	(in millions of dollars)
Investment-Grade	$	31,800.7	$	221.7	$	3,376.5	97.8	%
Below-Investment-Grade	1,193.8		6.2		75.1		2.2
Total Fixed Maturity Securities	$	32,994.5	$	227.9	$	3,451.6	100.0	%

The unrealized losses on investment-grade fixed maturity securities principally relate to changes in interest rates or changes in market or sector credit spreads which occurred subsequent to the acquisition of the securities. Below-investment-grade fixed maturity securities are generally more likely to develop credit concerns than investment-grade securities. At September 30, 2026, the unrealized losses in our below-investment-grade fixed maturity securities were generally due to credit spreads in certain industries or sectors and, to a lesser extent, credit concerns related to specific securities. For each specific security in an unrealized loss position, we believe that there are positive factors which mitigate credit concerns and that the securities for

which we have not recorded a credit loss will recover in value. We have the ability and intent to continue to hold these securities to recovery of amortized cost less allowance for credit losses.

As of September 30, 2026, we held 999 individual investment-grade fixed maturity securities and 87 individual below-investment-grade fixed maturity securities that were in an unrealized loss position, of which 702 investment-grade fixed maturity securities and 19 below-investment-grade fixed maturity securities had been in an unrealized loss position continuously for over one year.

In determining when a decline in fair value below amortized cost of a fixed maturity security represents a credit loss, we evaluate the following factors:

•Whether we expect to recover the entire amortized cost basis of the security

•Whether we intend to sell the security or will be required to sell the security before the recovery of its amortized cost basis

•Whether the security is current as to principal and interest payments

•The significance of the decline in value

•Current and future business prospects and trends of earnings

•The valuation of the security's underlying collateral

•Relevant industry conditions and trends relative to their historical cycles

•Market conditions

•Rating agency and governmental actions

•Bid and offering prices and the level of trading activity

•Adverse changes in estimated cash flows for securitized investments

•Changes in fair value subsequent to the balance sheet date

•Any other key measures for the related security

While determining whether a credit loss exists is a judgmental area, we utilize a formal, well-defined, and disciplined process to monitor and evaluate our fixed income investment portfolio, supported by issuer specific research and documentation as of the end of each period. The process results in a thorough evaluation of investments and the recording of credit losses on a timely basis for investments determined to have a credit loss. We calculate the allowance for credit losses of fixed maturity securities based on the present value of our best estimate of cash flows expected to be collected, discounted using the effective interest rate implicit in the security at the date of acquisition. When estimating future cash flows, we analyze the strength of the issuer’s balance sheet, its debt obligations and near-term funding arrangements, cash flow and liquidity, the profitability of its core businesses, the availability of marketable assets which could be sold to increase liquidity, its industry fundamentals and regulatory environment, and its access to capital markets.

The following tables present a rollforward of the allowance for credit losses on available-for-sale fixed maturity securities, which were classified as all other corporate bonds during the three and nine months ended September 30, 2026 and 2025.

At September 30, 2026, we had commitments of $182.6 million to fund private placement fixed maturity securities, the amount of which may or may not be funded. 

Variable Interest Entities

We invest in variable interests issued by variable interest entities. These investments, which are passive in nature, include minority ownership interests in private equity partnerships and special purpose entities. Our maximum exposure to loss is limited to the carrying value of these investments in private equity partnerships and special purpose entities. For those variable interests that are not consolidated in our financial statements, we are not the primary beneficiary because we have neither the power to direct the activities that are most significant to economic performance nor the responsibility to absorb a majority of the expected losses. The determination of whether we are the primary beneficiary is performed at the time of our initial investment and at the date of each subsequent reporting period.

As of September 30, 2026, the carrying amount of our variable interest entity investments not consolidated in our financial statements, which are primarily private equity partnerships, totaled $1,448.1 million. At December 31, 2025, the carrying amount of our variable interest entity investments not consolidated in our financial statements, which are primarily private equity partnerships, totaled $1,456.3 million. These variable interest entity investments are reported as other long-term investments in our consolidated balance sheets.

Mortgage Loans

Our mortgage loan portfolio is well diversified by both geographic region and property type to reduce risk of concentration. All of our mortgage loans are collateralized by commercial real estate. When issuing a new loan, our general policy is not to exceed a loan-to-value ratio, or the ratio of the loan balance to the estimated fair value of the underlying collateral, of 75 percent. We update the loan-to-value ratios based on internal valuation of the collateral at least every three years for each loan, and properties undergo a general inspection at least every two years. At loan origination, we compare the property net

operating income with debt service payments and generally target loans with a debt service coverage ratio above 1.2 times. We update our debt service coverage ratios annually.

We carry our mortgage loans at amortized cost less an allowance for expected credit losses. The amortized cost of our mortgage loans was $2,069.6 million and $2,125.4 million at September 30, 2026 and December 31, 2025, respectively. The allowance for expected credit losses was $16.4 million and $15.9 million at September 30, 2026 and December 31, 2025, respectively. Interest income is accrued on the principal amount of the loan based on the loan's contractual interest rate. We report accrued interest income for our mortgage loans as accrued investment income on our consolidated balance sheets, and the amount of the accrued income was $6.7 million at both September 30, 2026 and December 31, 2025.

The risk in our mortgage loan portfolio is primarily related to vacancy rates. Events or developments, such as economic conditions that impact the ability of the borrowers to ensure occupancy of the property, may have a negative effect on our mortgage loan portfolio, particularly to the extent that our portfolio is concentrated in an affected region or property type. An increase in vacancies increases the probability of default, which would negatively affect our expected losses in our mortgage loan portfolio.

We evaluate each of our mortgage loans individually for impairment and assign an internal quality rating based on a comprehensive rating system used to evaluate the risk of the loan. The factors we use to derive our internal quality ratings may include the following:

•Loan-to-value ratio based on internal valuation of the property

•Debt service coverage ratio based on current operating income

•Property location, including regional economics, trends, and demographics

•Age, condition, and construction quality of property

•Current and historical occupancy of property

•Lease terms relative to market

•Tenant size and financial strength

•Borrower's financial strength

•Borrower's equity in collateral

•Additional collateral, if any

Although all available and applicable factors are considered in our analysis, loan-to-value and debt service coverage ratios are the most critical factors in determining whether we will initially issue the loan and also in assigning values and determining impairment. We assign an overall rating to each loan using an internal rating scale of AA (highest quality) to B (lowest quality). We review and adjust, as needed, our internal quality ratings on an annual basis. This review process is performed more frequently for mortgage loans deemed to have a higher risk of delinquency.

We estimate an allowance for credit losses that we expect to incur over the life of our mortgage loans using a probability of default method. For each loan, we estimate the probability that the loan will default before its maturity (probability of default) and the amount of the loss if the loan defaults (loss given default). These two factors result in an expected loss percentage that is applied to the amortized cost of each loan to determine the expected credit loss. As we are the original underwriter of the mortgage loans, the amortized cost generally equals the principal amount of the loan. We measure losses on defaults of our mortgage loans as the excess amortized cost of the mortgage loan over the fair value of the underlying collateral in the event that we foreclose on the loan or over the expected future cash flows of the loan if we retain the mortgage loan until payoff. We do not purchase mortgage loans with existing credit impairments.

In estimating the probability of default, we consider historical experience, current market conditions, and reasonable and supportable forecasts about the future market conditions. We utilize our historical loan experience in combination with a large third-party industry database for a period of time that aligns with the average life of our loans based on the maturity dates of the loans and prepayment experience. Our model utilizes an industry database of the historical loss experience based on our actual portfolio characteristics such as loan-to-value, debt service coverage, collateral type, geography, and late payment history. In addition, because we actively manage our portfolio, we may extend the term of a loan in certain situations and will accordingly extend the maturity date in the estimate of probability of default. In estimating the loss given default, we primarily consider the type and value of collateral and secondarily the expected liquidation costs and time to recovery.

The primary market factors that we consider in our forecast of future market conditions are gross domestic product, unemployment rates, interest rates, inflation, commercial real estate values, household formation, and retail sales. We also forecast certain loan specific factors such as growth in the fair value and net operating income of collateral by property type. We include our estimate of these factors over a two-year period and for the remainder of the loans’ estimated lives, adjusted for estimated prepayments. Past the two-year forecast period, we revert to the historical assumptions ratably by the end of the fifth year of the loan after which we utilize only historical assumptions.

We utilize various scenarios to estimate our allowance for expected losses ranging from a base case scenario that reflects normal market conditions to a severe case scenario that reflects adverse market conditions. We will adjust our allowance each period to utilize the scenario or weighting of the scenarios that best reflects our view of current market conditions.

During the nine months ended September 30, 2026, no commercial mortgage loans were modified for borrowers experiencing financial difficulties. During the nine months ended September 30, 2025, we granted an other-than-insignificant payment delay for a commercial mortgage loan with an amortized cost of $14.2 million, which deferred the principal payment for 24 months. This modification represents less than one percent of the commercial mortgage loan portfolio balance. For the three and nine months ended September 30, 2026 and 2025, all commercial loans which were previously modified for borrowers experiencing financial difficulties were current.

As of September 30, 2026 and December 31, 2025, we held no specifically identified impaired mortgage loans. As of September 30, 2025 we held one specifically identified impaired mortgage loan with a carrying value of $8.4 million that was past due regarding principal and/or interest payments. During the three months ended September 30, 2025, it was determined that this loan required further impairment, resulting in a $0.8 million write-off. During the fourth quarter of 2025, the property securing the loan was sold, resulting in a loss on disposal of $1.1 million. No interest income was recognized on this loan following impairment. There were no commercial mortgage loans past due as to principal and/or interest payments as of September 30, 2026 and December 31, 2025.

As of September 30, 2026 and December 31, 2025, we had no commercial mortgage loan foreclosures.

At September 30, 2026, we had $11.1 million of commitments to fund commercial mortgage loans. We estimate expected credit losses for loans that have not been funded but we are committed to fund at the end of each period using consistent methodology as our current expected credit losses for our funded mortgage loans. At September 30, 2026 and December 31, 2025, we had a nominal amount and no amount, respectively, of expected credit losses related to unfunded commitments on our consolidated balance sheets.

Investment Real Estate

Our investment real estate held for the production of income balance was $60.8 million and $41.7 million at September 30, 2026 and December 31, 2025, respectively, and the associated accumulated depreciation was $204.3 million and $130.1 million at September 30, 2026 and December 31, 2025, respectively. We monitor and assess our real estate investments for impairment when facts and circumstances indicate that the real estate may be impaired.

Our held for sale real estate balance was $5.0 million and $41.9 million at September 30, 2026 and December 31, 2025 and the associated accumulated depreciation was $4.7 million and $57.5 million at September 30, 2026 and December 31, 2025, respectively. The estimated fair values less costs to sell are above the carrying values of the properties and we expect to close the sales of the properties within the next twelve months.

Transfers of Financial Assets

To manage our cash position more efficiently, we may enter into repurchase agreements with unaffiliated financial institutions. We generally use repurchase agreements as a means to finance the purchase of invested assets or for short-term general business purposes until projected cash flows become available from our operations or existing investments. Our repurchase agreements are typically outstanding for less than 30 days. We post collateral through our repurchase agreement transactions whereby the counterparty commits to purchase securities with the agreement to resell them to us at a later, specified date. The fair value of collateral posted is generally 102 percent of the cash received.

Our investment policy also permits us to lend fixed maturity securities to unaffiliated financial institutions in short-term securities lending agreements. These agreements increase our investment income with minimal risk. Our securities lending policy requires that a minimum of 102 percent of the fair value of the securities loaned be maintained as collateral. We may receive cash and/or securities as collateral under these agreements. Cash received as collateral is typically reinvested in short-term investments. If securities are received as collateral, we are not permitted to sell or re-post them.

As of September 30, 2026, the carrying amount of fixed maturity securities loaned to third parties under our securities lending program was $99.2 million, for which we received collateral in the form of cash and securities of $62.9 million and $40.3 million, respectively. As of December 31, 2025, the carrying amount of fixed maturity securities loaned to third parties under our securities lending program was $106.1 million, for which we received collateral in the form of cash and securities of $76.1 million and $34.1 million, respectively. We had no outstanding repurchase agreements at September 30, 2026 or December 31, 2025.

The remaining contractual maturities of our securities lending agreements disaggregated by class of collateral pledged are as follows:

Certain of our U.S. insurance subsidiaries are members of regional FHLBs. As members of the FHLBs, our insurance subsidiaries have the ability to borrow on a collateralized basis from the FHLBs. Each member is required to hold a certain minimum amount of FHLB common stock as a condition of membership and additional amounts based on the amount of the borrowings. Advances received from the FHLB are primarily used for the purchase of short-term investments, matched fixed maturity securities, or matched commercial mortgage loans. The carrying value of common stock owned at September 30, 2026 and December 31, 2025 was $50.4 million and $40.7 million, respectively.

Funding Agreement-Backed Loan Program

During February 2026, we established a funding agreement-backed loan (FABL) program, pursuant to which a special purpose unaffiliated Delaware statutory trust (the FABL trust) may borrow funds under a six-month delayed draw term loan facility (the facility) and deposit the proceeds with Colonial Life & Accident Insurance Company (Colonial Life & Accident), a wholly owned insurance subsidiary, pursuant to funding agreements issued by Colonial Life & Accident to the FABL trust. Colonial Life & Accident does not hold any variable interests in the FABL trust. The deposits received by Colonial Life & Accident under the funding agreements will be used for spread lending purposes. The facility permits borrowings by the FABL trust in two tranches, in an aggregate principal amount of up to $500.0 million, with scheduled maturities on the third and fifth anniversaries, respectively, of the date that is six months after the date of the applicable credit agreement. The funding agreements issued by Colonial Life & Accident will have matching interest, maturity and payment terms to the applicable borrowings by the FABL trust. The funding agreements may be collateralized by eligible securities, including agency securities, corporate bonds, municipal bonds, and U.S. Treasury securities. As of September 30, 2026, the funding agreements had been fully collateralized and Colonial Life & Accident had principal outstanding of $500.0 million which are included in policyholders' account balances on the consolidated balance sheets.

Assets Pledged as Collateral

We maintain borrowing and liquidity facilities that require pledging of collateral, such as FHLB advances. Other arrangements, including FABL and standby letter of credit facilities allow us to pledge collateral as needed. See Note 14 for more information regarding our standby letter of credit facilities. The carrying value of collateral pledged and related obligations outstanding were as follows:

Offsetting of Financial Instruments

We enter into master netting agreements with each of our derivative's counterparties. These agreements provide for conditional rights of set-off upon the occurrence of an early termination event. An early termination event is considered a default, and it allows the non-defaulting party to offset its contracts in a loss position against any gain positions or payments due to the defaulting party. Under our agreements, default type events are defined as failure to pay or deliver as contractually agreed, misrepresentation, bankruptcy, or merger without assumption. See Note 5 for further discussion of collateral related to our derivative contracts.

We have securities lending agreements with unaffiliated financial institutions that post collateral to us in return for the use of our fixed maturity securities. A right of set-off exists that allows us to keep and apply collateral received in the event of default by the counterparty. Default within a securities lending agreement would typically occur if the counterparty failed to return the securities borrowed from us as contractually agreed. In addition, if we default by not returning collateral received, the counterparty has a right of set-off against our securities or any other amounts due to us.

Shown below are our financial instruments that either meet the accounting requirements that allow them to be offset in our balance sheets or that are subject to an enforceable master netting arrangement or similar agreement. Our accounting policy is to not offset these financial instruments in our balance sheets. Net amounts disclosed below have been reduced by the amount of collateral pledged to or received from our counterparties.

(Fortitude Re). Our investment gains and losses on fixed maturity securities for the third quarter and first nine months of 2025 were driven primarily by the Closed Block long-term care and Unum US individual disability reinsurance transaction (2025 Fortitude Re reinsurance transaction) which resulted in a net gain of $137.6 million in the third quarter of 2025 and a net loss of $46.8 million in the first nine months of 2025. We also realized a $19.1 million loss on sales of fixed maturity securities related to the funding of an extraordinary dividend from a wholly owned insurance subsidiary to Unum Group in the first nine months of 2025.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Note 5 - Derivative Financial Instruments

Purpose of Derivatives

We are exposed to certain risks relating to our ongoing business operations and anticipated reinsurance transactions. The primary risks managed by using derivative instruments are interest rate risk, risk related to matching duration for our assets and liabilities, foreign currency risk, credit risk, and equity risk. Historically, we have utilized current and forward interest rate swaps, current and forward currency swaps, forward benchmark interest rate locks, currency forward contracts, forward contracts on specific fixed income securities, and total return swaps. Transactions hedging interest rate risk are primarily associated with our individual and group long-term care and individual and group disability products. All other product portfolios are periodically reviewed to determine if hedging strategies would be appropriate for risk management purposes. We do not use derivative financial instruments for speculative purposes.

Derivatives designated as cash flow hedges and used to reduce our exposure to interest rate and duration risk are as follows:

•Interest rate swaps were used to hedge interest rate risks and to improve the matching of assets and liabilities. An interest rate swap is an agreement in which we agree with other parties to exchange, at specified intervals, the difference between fixed rate and variable rate interest amounts. We used interest rate swaps to hedge the anticipated purchase of fixed maturity securities thereby protecting us from the potential adverse impact of declining interest rates

on the associated policy reserves. We also used interest rate swaps to hedge the potential adverse impact of rising interest rates in anticipation of issuing fixed rate long-term debt.

•Forward benchmark interest rate locks are used to minimize interest rate risk associated with the anticipated purchase or associated future coupons of fixed maturity securities or the anticipated issuance of fixed rate long-term debt. A forward benchmark interest rate lock is a derivative contract without an initial investment where we and the counterparty agree to purchase or sell a specific benchmark interest rate fixed maturity bond at a future date at a predetermined price or yield.

Derivatives designated as either cash flow or fair value hedges and used to reduce our exposure to foreign currency risk are as follows:

•Foreign currency interest rate swaps are used to hedge the currency risk of certain foreign currency-denominated fixed maturity securities owned for portfolio diversification. Under these swap agreements, we agree to pay, at specified intervals, fixed rate foreign currency-denominated principal and interest payments in exchange for fixed rate payments in the functional currency of the operating segment.

Derivatives not designated as hedging instruments, which are used to reduce our exposure to foreign currency risk, volatility of the underlying deferred assets in our non-qualified defined contribution plan, credit risk, interest rate risk, and duration risk are as follows:

•Foreign currency interest rate swaps previously designated as hedges were used to hedge the currency risk of certain foreign currency-denominated fixed maturity securities owned for portfolio diversification. These derivatives were effective hedges prior to novation to a new counterparty. In conjunction with the novation, these derivatives were de-designated as hedges. We agree to pay, at specified intervals, fixed rate foreign currency-denominated principal and interest payments in exchange for fixed rate payments in the functional currency of the operating segment. We hold offsetting swaps wherein we agree to pay fixed rate principal and interest payments in the functional currency of the operating segment in exchange for fixed rate foreign currency-denominated payments.

•Foreign currency forward contracts are used to minimize foreign currency risk. A foreign currency forward is a derivative without an initial investment where we and the counterparty agree to exchange a specific amount of currencies, at a specific exchange rate, on a specific date. We use these forward contracts to hedge the currency risk arising from foreign-currency denominated investments.

•Total return swaps are used to economically hedge a portion of the liability related to our non-qualified defined contribution plan. They are also used to economically hedge the interest rate and duration risk associated with a portion of the consideration payable upon closing of the 2026 Fortitude Re reinsurance transaction. In addition, we have used total return swaps to hedge the economic risk from credit spread and interest rate duration exposure related to certain cash and cash equivalent amounts. A total return swap is an agreement in which we pay a floating rate of interest and a spread to the counterparty and receive the total return on a portfolio of mutual funds and/or exchange traded funds. These swaps may be settled/reset periodically during the term of the contract or at maturity, depending on the terms of the underlying agreement.

•Forward benchmark interest rate locks are used to hedge interest rate and duration risk associated with a portion of the consideration payable upon closing of the 2026 Fortitude Re reinsurance transaction. A forward benchmark interest rate lock is a derivative contract without an initial investment where we and the counterparty agree to purchase or sell a specific benchmark interest rate fixed maturity bond at a future date at a predetermined price or yield.

•Interest rate swaps are used to economically hedge interest rate risk associated with certain floating rate liabilities. An interest rate swap is an agreement in which we agree with other parties to exchange, at specified intervals, the difference between fixed rate and variable rate interest amounts. We use these interest rate swaps to reduce the variability of cash flows associated with certain floating rate liabilities.

Derivative Risks

The basic types of risks associated with derivatives are market risk (that the value of the derivative will be adversely impacted by changes in the market, primarily changes in interest rates, exchange rates, and equity prices) and credit risk (that the counterparty will not perform according to the terms of the contract). The market risk of the derivatives should generally offset the market risk associated with the hedged financial instrument or liability. To help limit the credit exposure of the derivatives, we enter into master netting agreements with our counterparties whereby contracts in a gain position can be offset against contracts in a loss position. We also typically enter into bilateral, cross-collateralization agreements with our counterparties to help limit the credit exposure of the derivatives. These agreements require the counterparty in a loss position to submit acceptable collateral with the other counterparty in the event the net loss position meets or exceeds an agreed upon amount. Credit exposure on derivatives is limited to the value of those contracts in a net gain position, including accrued interest receivable less collateral held. At September 30, 2026, we had $2.2 million credit exposure on derivatives. At December 31, 2025, we had no credit exposure on derivatives. The table below summarizes the nature and amount of collateral received from and posted to our derivative counterparties.

	September 30, 2026		December 31, 2025
	(in millions of dollars)

Carrying Value of Collateral Posted to Counterparties
Cash	$	7.7	$	—
Fixed Maturity Securities	439.6		244.3
	$	447.3	$	244.3

See Note 4 for further discussion of our master netting agreements.

All of our derivative instruments contain provisions that require us to maintain specified issuer credit ratings and financial strength ratings. Should our ratings fall below these specified levels, we would be in violation of the provisions, and our derivatives counterparties could terminate our contracts and request immediate payment. The aggregate fair value of all derivative instruments with credit risk-related contingent features that were in a liability position was $421.5 million and $269.7 million at September 30, 2026 and December 31, 2025, respectively.

Cash Flow Hedges

As of September 30, 2026 and December 31, 2025, we had $109.2 million and $127.3 million, respectively, notional amount of receive fixed, pay fixed, open current and forward foreign currency interest rate swaps to hedge fixed income foreign currency-denominated securities.

As of September 30, 2026 and December 31, 2025, we had $2,311.0 million and $2,603.0 million, respectively, notional amount of forward benchmark interest rate locks to hedge the anticipated purchase of fixed maturity securities.

As of September 30, 2026, we expect to amortize approximately $(0.4) million of net deferred losses on derivative instruments during the next twelve months. This amount will be reclassified from AOCI into earnings and reported on the same income statement line item as the hedged item. The income statement line items that will be affected by this amortization are net investment income and interest and debt expense. Additional amounts that may be reclassified from AOCI into earnings to offset the earnings impact of foreign currency translation of hedged items are not estimable.

As of September 30, 2026, we are hedging the variability of future cash flows associated with forecasted transactions through the year 2053.

Fair Value Hedges

As of September 30, 2026 and December 31, 2025, we had $848.0 million and $768.6 million, respectively, notional amount of receive fixed, pay fixed, open current and forward foreign currency interest rate swaps to hedge fixed income foreign currency-denominated securities.

The following tables summarize the amortized cost, carrying amount of hedged assets, and the related cumulative basis adjustments related to our fair value hedges.

	September 30, 2026
	(in millions of dollars)

For the three and nine months ended September 30, 2026, $(16.1) million and $(23.5) million, respectively, of the derivative instruments' gain (loss) related to cross-currency basis spread and forward points was excluded from the assessment of hedge effectiveness. For the three and nine months ended September 30, 2025, $6.4 million and $31.3 million, respectively, of the derivative instruments' gain (loss) related to cross-currency basis spread and forward points was excluded from the assessment of hedge effectiveness. There were no instances wherein we discontinued fair value hedge accounting due to a hedged firm commitment no longer qualifying as a fair value hedge.

Derivatives not Designated as Hedging Instruments

As of September 30, 2026 and December 31, 2025, we held $82.9 million and $115.6 million, respectively, notional amount of receive fixed, pay fixed, foreign currency interest rate swaps. These derivatives are not designated as hedges, and as such, changes in fair value related to these derivatives are reported in earnings as a component of net investment gain or loss.

As of September 30, 2026 and December 31, 2025, we held $45.8 million and $48.9 million, respectively, notional amount of foreign currency forwards to mitigate the foreign currency risk associated with specific securities owned. These derivatives are not designated as hedges, and as such, changes in fair value related to these derivatives are reported in earnings as a component of net investment gain or loss.

As of September 30, 2026 and December 31, 2025, we held $172.5 million and $154.8 million, respectively, notional amount of total return swaps to mitigate the volatility associated with changes in the fair value of the underlying notional assets in our non-qualified defined contribution plan. This derivative is an economic hedge not designated as a hedging instrument, and changes in fair value are reported as a component of other expenses in our consolidated statements of operations.

As of September 30, 2026 and December 31, 2025, we held total return swap contracts with notional amounts of $549.8 million and zero, respectively, and forward benchmark interest rate lock contracts with notional amounts of $832.0 million and zero, respectively, to economically hedge risks associated with consideration payable in connection with reinsurance transactions with Fortitude Re. These derivatives are not designated as hedging instruments. Changes in fair value are reported in consolidated statements of operations in net investment gain or loss. Contract settlements, dividend payments, and financing costs are reported in net investment income. During 2025, we entered into a $700.0 million total return swap related to a reinsurance transaction with Fortitude Re that was unwound and settled for cash in the second quarter of 2025.

As of September 30, 2026, we held interest rate swap contracts with a notional amount of $205.8 million to mitigate interest rate risk associated with certain floating rate liabilities associated with our spread lending program. No such derivatives were held as of December 31, 2025. These derivatives are not designated as hedging instruments, and as such, changes in fair value related to these derivatives are reported in earnings as a component of net investment gain or loss. Net interest settlements are reported in earnings as a component of net investment income.

We have an embedded derivative in a modified coinsurance arrangement, for which we include in our net investment gains and losses a calculation intended to estimate the value of the option of our reinsurance counterparty to cancel the reinsurance contract with us. However, neither party can unilaterally terminate the reinsurance agreement except in extreme circumstances resulting from regulatory supervision, delinquency proceedings, or other direct regulatory action. Cash settlements or collateral related to this embedded derivative are not required at any time during the reinsurance contract or at termination of the reinsurance contract. There are no credit-related counterparty triggers, and any accumulated embedded derivative gain or loss reduces to zero over time as the reinsured business winds down.

Liability for Future Policy Benefits, Policyholder's Account Balances, and Deferred Acquisition Costs

9 Months Ended

Sep. 30, 2026

Insurance [Abstract]

Long-Duration Insurance Contracts Disclosure

Liabilities for future policy benefits represent the cost of claims that we estimate we will eventually pay to our policyholders which includes policy liabilities for claims not yet incurred and for claims that have been incurred or are estimated to have been incurred but not yet reported to us. Liabilities for future policy benefits also include the related expenses for our non interest-sensitive life and accident and health products. The liability for future policy benefits is calculated based on the present value of the estimated future policy benefits less the present value of estimated future net premiums collected. Net premiums represent the portion of the gross premium required to provide for all benefits and expenses, excluding acquisition costs or any costs that are required to be charged to expense as incurred. Insureds who have experienced an insured event and for whom future benefit payments are expected after the reporting date are considered to be on claim. For Unum US group disability, Unum US group life and accidental death and dismemberment, Unum UK group disability, and Unum UK group life policies, the tables presenting the balances and changes in the liability for future policy benefits represent only insureds on claim, as there is generally no liability for future policy benefits for insureds not on claim. Therefore, the present value of expected net premiums and expected future gross premiums (both discounted and undiscounted) for Unum US group disability, Unum US group life and accidental death and dismemberment, Unum UK group disability, and Unum UK group life products will generally be zero, as we generally do not collect premium from insureds on claim. In calculating the liability for future policy benefits, our long-duration contracts are grouped into cohorts by product type and contract issue year.

The calculation of the liability for future policy benefits involves numerous assumptions including assumptions related to discount rate, lapses, mortality, and morbidity. Cash flow assumptions are reviewed and updated, as needed, at least annually. Assumptions may be updated more frequently if necessary based on trending experience and future expectations. On a quarterly basis, cohort level cash flow measures are updated based on the emergence of actual experience.

The initial, also referred to as the original, discount rate assumptions established for each cohort are used to determine interest accretion. After policy issuance or policy renewal, the discount rate assumptions are updated quarterly and used to update the liability at each reporting date to the current discount rate. The weighted average current discount rate was 6.0 percent at September 30, 2026 compared to 5.1 percent at December 31, 2025 with the increase due primarily to an increase in U.S. Treasury rates. The weighted average current discount rate was 5.1 percent at September 30, 2025 and 5.3 percent at December 31, 2024 with the decrease due primarily to a decrease in U.S. Treasury rates.

During the third quarter of 2026, we completed our annual cash flow assumption review and updated certain assumptions used to develop the liability for future policy benefits which resulted in a net decrease to the liability. The decrease to the liability for future policy benefits was driven primarily by the impact of assumption updates in our Colonial Life segment and Unum US group disability product line, partially offset by the impact of assumption updates in the Closed Block long-term care product line and in the Unum International segment. The Colonial Life assumption updates were primarily driven by lower expectations for morbidity assumptions, increased policyholder lapse rates, and lower mortality assumptions. The Unum US group disability product line assumption updates were primarily driven by favorable social security benefit offsets and claim recovery trends, partially offset by higher claim incidence. The Closed Block long-term care assumption updates were primarily driven by higher expectations for claim incidence assumptions and lower expectations for mortality assumptions, partially offset by an increase to expected future premium rate approvals. The Unum International segment assumption updates were primarily driven by higher claim incidence assumptions for our Unum UK group disability product line.

During the third quarter of 2025, we completed our annual cash flow assumption review and updated certain assumptions used to develop the liability for future policy benefits which resulted in a net increase to the liability. The increase to the liability for future policy benefits was driven primarily by the impact of assumption updates in our Closed Block long-term care product line, partially offset by the impact of assumption updates in the Unum US group disability product line and our Unum US individual disability product line. The Closed Block long-term care assumption updates were primarily driven by the removal of morbidity and mortality improvement assumptions. Also contributing were higher expectations for claim incidence assumptions, and the removal of future assumptions related to new enrollments on existing group cases, partially offset by an increase to expected future premium rate approvals and higher expectations for claim terminations. The Unum US group disability product line assumption updates were primarily related to claim resolution assumptions driven by favorable claim recovery trends and higher mortality expectations, while the Unum US individual disability product line assumption updates were primarily driven by favorable claim incidence and recovery trends.

Actual variance from expected experience during the first nine months of 2026 was due primarily to the Closed Block long-term care and Unum US group life and accidental death and dismemberment product lines. The variance in the Closed Block long-term care product line was primarily due to higher group long-term care policy terminations and related port activity, higher than expected claim incidence, and lower than expected claim terminations. The variance in the Unum US group life and accidental death and dismemberment product line was driven primarily by lower than expected claim incidence.

Actual variance from expected experience during the first nine months of 2025 was due primarily to the Closed Block long-term care, Unum US group disability, Unum US group life and accidental death and dismemberment, and Closed Block all other product lines. The variance in the Closed Block long-term care product line was primarily due to higher than expected claim incidence and mortality experience. The variance in the Unum US group disability and group life and accidental death and dismemberment product lines was primarily due to higher than expected claim resolutions driven by recoveries. Also impacting the variance in the Unum US group life and accidental death and dismemberment product line was lower than expected claim incidence. The variance in the Closed Block all other product line was driven primarily by higher than expected mortality experience driven by our individual disability product.

For the nine months ended September 30, 2026 and 2025, there were certain cohorts within the Closed Block segment, related to our long-term care product line, and within the Colonial Life segment, related to our cancer and critical illness product line for which net premiums exceed gross premiums. The cohorts for which net premiums exceeded the gross premiums within the Closed Block segment resulted in a $121.6 million reduction to income before income tax for the nine months ended September 30, 2026 and resulted in a $425.6 million reduction to income before income tax for the nine months ended September 30, 2025. There were also certain cohorts within the Colonial Life segment for which net premiums exceeded gross premiums which had an immaterial impact to income before income tax for the nine months ended September 30, 2026. The cohorts for which net premiums exceeded the gross premiums within the Colonial Life segment for the nine months ended September 30, 2025 resulted in a $10.9 million reduction to income before income tax. The impact to income for capped cohorts includes the impact of assumption updates. There were no other product lines with cohorts for which net premiums exceeded gross premiums for the nine months ended September 30, 2026 or 2025.

Policyholders' account balances primarily include universal life, corporate-owned life insurance, and certain funding agreements. Policyholders' account balances reflect policyholder deposits and interest credited less cost of insurance, administration expenses, surrender charges, and withdrawals.

The following table presents the balances and changes in the policyholders' account balances:

We report goodwill in our Unum US, Unum International, and Colonial Life segments, which are the segments expected to benefit from the originating business combinations. At September 30, 2026 and December 31, 2025 goodwill was $352.9 million and $353.9 million, respectively, with $281.2 million attributable to Unum US in both periods, $44.0 million and $45.0 million, respectively, attributable to Unum International, and $27.7 million attributable to Colonial Life in both periods.

We measure and analyze our segment performance on the basis of "segment adjusted operating revenue" and "segment adjusted operating income" or "segment adjusted operating loss", which differ from total revenue and income before income tax as presented in our consolidated statements of operations due to the exclusion of investment gains and losses and certain other items. The excluded items impacting the periods presented herein are specified in the reconciliations below. We believe segment adjusted operating revenue and segment adjusted operating income or loss are better performance measures and better indicators of the revenue and profitability and underlying trends in our business. These performance measures are in accordance with GAAP guidance for segment reporting, but they should not be viewed as a substitute for total revenue, income before income tax, or net income.

Investment gains or losses primarily include realized investment gains or losses, expected investment credit losses, impairment losses, and gains or losses on derivatives. Investment gains or losses depend on market conditions and do not necessarily relate to decisions regarding the underlying business of our segments. Our investment focus is on investment income to support our insurance liabilities as opposed to the generation of investment gains or losses. Although we may experience investment gains or losses which will affect future earnings levels, a long-term focus is necessary to maintain profitability over the life of the business since our underlying business is long-term in nature, and we need to earn the interest rates assumed in calculating our liabilities.

We have completed reinsurance transactions to exit significant portions of our Closed Block businesses and we are no longer accepting new enrollments on existing group long-term care policies. As a result of these actions and the continued run-off of the Closed Block business, we determined that it is no longer necessary to adjust segment adjusted operating revenue or segment adjusted operating income or loss to exclude the amortization of the deferred gain on reinsurance and it is no longer necessary to adjust segment adjusted operating income or loss to exclude the amortization of the cost of reinsurance, the amortization of the deferred gain on reinsurance or the impact of non-contemporaneous reinsurance, because the majority of these items are included in Closed Block segment results. Prior period financial information has been adjusted to conform to this updated presentation.

We may at other times exclude certain other items from our discussion of financial ratios and metrics in order to enhance the understanding and comparability of our operational performance and the underlying fundamentals, but this exclusion is not an indication that similar items may not recur and does not replace net income or net loss as a measure of our overall profitability.

We no longer exclude reserve assumption updates from our adjusted operating results, and prior period financial information has been adjusted to conform to this updated presentation.

Strategic Actions

In connection with our transition to an updated operating model, during the second quarter of 2026, we recognized expenses of $30.7 million. This included $18.0 million in real estate-related costs, including $16.3 million of depreciation expense associated with investment real estate which is reflected within net investment income in the consolidated statements of operations. In addition, we incurred employee-related costs of $12.7 million, with $11.2 million reflected within compensation expense in the consolidated statements of operations and we expect payments to occur through 2027. These costs were included within our Corporate segment.

A reconciliation of total revenue to "segment adjusted operating revenue" and income (loss) before income tax to "segment adjusted operating income (loss)" is as follows:

Defined Benefit Pension and Other Postretirement Benefit (OPEB) Plans

We sponsor several defined benefit pension and OPEB plans for our employees, including non-qualified pension plans. The U.S. qualified and non-qualified defined benefit pension plans comprise the majority of our total benefit obligation and benefit cost. We maintain a separate defined benefit plan for eligible employees in our U.K. operation. The U.S. defined benefit pension plans were frozen and closed to new entrants on December 31, 2013, the OPEB plan was frozen and closed to new entrants on December 31, 2012, and the U.K. plan was frozen and closed to new entrants on December 31, 2002.

Stockholders' Equity and Earnings Per Common Share [Abstract]

Earnings Per Share Disclosure

Earnings (Loss) Per Common Share

Net income (loss) per common share is determined as follows:

	Three Months Ended September 30				Nine Months Ended September 30
	2026		2025		2026		2025
	(in millions of dollars, except share data)
Numerator

Weighted Average Common Shares - Basic	158,607.3		170,248.1		159,355.6		174,152.5

Weighted Average Common Shares - Assuming Dilution	158,607.3		170,588.8		159,735.2		174,570.0
Net Income (Loss) Per Common Share

Assuming Dilution	$	(2.65)	$	0.23	$	0.43	$	3.23

We compute basic earnings per share by dividing net income by the weighted average number of common shares outstanding for the period. In computing earnings per share assuming dilution, we include potential common shares that are dilutive (those that reduce earnings per share). We use the treasury stock method to account for the effect of nonvested restricted stock units and nonvested performance share units on the computation of diluted earnings per share. Under this method, the potential common shares from nonvested restricted stock units and nonvested performance share units will each have a dilutive effect, as individually measured, when the average market price of Unum Group common stock during the period exceeds the grant price of the nonvested restricted stock units and nonvested performance share units. The outstanding nonvested restricted stock units and nonvested performance share units have grant prices ranging from $44.75 to $94.07.

Antidilutive shares of 0.4 million and 0.1 million for the three and nine months ended September 30, 2026, respectively, were not included in the computation of diluted earnings per share because the impact would be antidilutive based on then current market prices and the effects of reporting a net loss. There were 0.3 million potential common shares that were antidilutive for the three and nine months ended September 30, 2025.

Stockholders' Equity Disclosure

Common Stock

As part of our capital deployment strategy, we may repurchase shares of Unum Group's common stock, as authorized by our board of directors. The timing and amount of repurchase activity is based on market conditions and other considerations, including the level of available cash, alternative uses for cash, and our stock price.

Our board of directors has authorized the following repurchase programs:

	August 2026 Authorization		December 2025 Authorization1		February 2025 Authorization2		July 2024 Authorization3

1Concurrent with the announcement of the August 2026 repurchase program, we also announced the termination of the December 2025 program as of August 31, 2026, and all unused amounts under that program expired as of that date.

2Concurrent with the announcement of the December 2025 repurchase program, we also announced the termination of the February 2025 program as of December 31, 2025, and all unused amounts under that program expired as of that date.

3Concurrent with the announcement of the February 2025 repurchase program, we also announced the termination of the July 2024 program as of March 31, 2025, and all unused amounts under that program expired as of that date.

Common stock repurchases, which are accounted for using the cost method and classified as treasury stock until otherwise retired, were as follows:

	Three Months Ended September 30				Nine Months Ended September 30

Cost of Shares Repurchased2	$	202.0	$	253.3	$	806.5	$	759.2

1For the nine months ended September 30, 2025, includes 0.7 million shares related to the settlement of the November 2024 accelerated share repurchase agreement (ASR) which occurred in February 2025.

2Includes a de minimis amount and $0.3 million of commissions for the three and nine months ended September 30, 2026, respectively, and $0.9 million and $1.8 million of commissions for the three and nine months ended September 30, 2025. Also includes $2.0 million and $7.7 million of excise tax for the three and nine months ended September 30, 2026, respectively, and $2.4 million and $7.4 million of excise tax for the three and nine months ended September 30, 2025, respectively.

As a part of our share repurchase program, we periodically enter into accelerated share repurchase agreements. Under the terms of these agreements, we make a prepayment to a financial counterparty for which we receive an initial delivery of approximately 75 percent of the total Unum Group common stock to be delivered under the agreement. We simultaneously enter into a forward contract indexed to the price of Unum Group common stock, which subjects the transactions to a future price adjustment. Under the terms of the agreements, we are to receive, or be required to pay, a price adjustment based on the volume weighted average price of Unum Group common stock during the term of the agreement, less a discount. Any price adjustment payable to us is settled in shares of Unum Group common stock. Any price adjustment we would be required to pay may be settled in either cash or common stock at our option. In November 2024, we paid $321.0 million to a financial counterparty as a part of an accelerated share repurchase agreement. We received an initial delivery of 3.8 million shares of our common stock. The final price adjustment settlement, along with the delivery of the remaining shares, occurred in February 2025, resulting in the delivery to us of 0.7 million additional shares. As a result of the final settlement occurring subsequent to December 31, 2024, we recorded a decrease of $80.3 million to additional paid-in capital within stockholders' equity on our

consolidated balance sheet for the value of the shares held back by the counterparty as of December 31, 2024, which was reclassified to treasury stock in the first quarter of 2025 in connection with the final settlement of the agreement.

Preferred Stock

Unum Group has 25.0 million shares of preferred stock authorized with a par value of $0.10 per share. No preferred stock has been issued to date.

Commitments and Contingent Liabilities

Sep. 30, 2026

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies Disclosure

Commitments

See Notes 3 and 4 for further discussion on certain of our investment commitments.

Contingent Liabilities

We are a defendant in a number of litigation matters that have arisen in the normal course of business, including the matters discussed below. Further, state insurance regulatory authorities and other federal and state authorities regularly make inquiries and conduct investigations concerning our compliance with applicable insurance and other laws and regulations. Given the complexity and scope of our litigation and regulatory matters, it is not possible to predict the ultimate outcome of all pending investigations or legal proceedings or provide reasonable estimates of potential losses, except if noted in connection with specific matters.

In some of these matters, no specified amount is sought. In others, very large or indeterminate amounts, including punitive and treble damages, are asserted. There is a wide variation of pleading practice permitted in the United States courts with respect to requests for monetary damages, including some courts in which no specified amount is required and others which allow the plaintiff to state only that the amount sought is sufficient to invoke the jurisdiction of that court. Further, some jurisdictions permit plaintiffs to allege damages well in excess of reasonably possible verdicts. Based on our extensive experience and that of others in the industry with respect to litigating or resolving claims through settlement over an extended period of time, we believe that the monetary damages asserted in a lawsuit or claim bear little relation to the merits of the case, or the likely disposition value. Therefore, the specific monetary relief sought is not stated.

Unless indicated otherwise, reserves have not been established for litigation and contingencies. An estimated loss is accrued when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated.

Claim Handling Matters

We and our insurance subsidiaries, in the ordinary course of our business, are engaged in claim litigation where disputes arise as a result of a denial or termination of benefits. Most typically these lawsuits are filed on behalf of a single claimant or policyholder, and in some of these individual actions punitive damages are sought, such as claims alleging bad faith in the handling of insurance claims. For our general claim litigation, we maintain reserves based on experience to satisfy judgments and settlements in the normal course. We expect that the ultimate liability, if any, with respect to general claim litigation, after consideration of the reserves maintained, will not be material to our consolidated financial condition. Nevertheless, given the inherent unpredictability of litigation, it is possible that an adverse outcome in certain claim litigation involving punitive damages could, from time to time, have a material adverse effect on our consolidated results of operations in a period, depending on the results of operations for the particular period.

From time to time class action allegations are pursued where the claimant or policyholder purports to represent a larger number of individuals who are similarly situated. Since each insurance claim is evaluated based on its own merits, there is rarely a single act or series of actions which can properly be addressed by a class action. Nevertheless, we monitor these cases closely and defend ourselves appropriately where these allegations are made.

Debt and Other Disclosures [Abstract]

Debt

Credit Facilities

In November 2026, Provident Life and Accident Insurance Company (Provident), one of our traditional U.S. life insurance subsidiaries, entered into a five-year senior standby letter of credit facility to support potential funding obligations under the experience volatility cover related to the 2026 Fortitude Re reinsurance transaction with an initial commitment of $139.1 million, and annual increases up to a maximum of $172.4 million. The facility has an initial maturity date in November 2031 and is automatically extended annually for an additional twelve-month period, unless terminated. If the letter of credit is drawn, reimbursement would have interest based on the prime rate. As of the date of this filing, a letter of credit totaling $139.1 million had been issued.

In July 2026, we terminated our five-year, £75.0 million senior unsecured standby letter of credit facility, which was originally set to expire in December 2028. Also, our additional five-year, £75.0 million senior unsecured standby letter of credit facility expired, as scheduled, in July 2026. There were no borrowed amounts outstanding at the time of termination or expiration of these facilities.

Also in July 2026, we entered into a new five-year, £75.0 million senior standby letter of credit facility pursuant to which a £75.0 million letter of credit was issued in favor of Unum Limited (as beneficiary), our U.K. insurance subsidiary, and is available for borrowings up to £75.0 million until its scheduled expiration in July 2031. The credit facility provides for borrowings at an interest rate based on the Sterling Overnight Index Average rate. The credit facility may be collateralized by cash and eligible securities, including asset-backed securities, agency securities, corporate bonds and U.S. Treasury securities. As of September 30, 2026, the credit facility has not been collateralized. As of September 30, 2026, there were no borrowed amounts outstanding under the credit facility.

In April 2026, we entered into a senior letter of credit facility pursuant to which a £50.0 million letter of credit was issued in favor of Unum Limited (as beneficiary). The facility provides for drawings up to £50.0 million until its scheduled expiration five years after issuance of the letter of credit and no later than July 2031. The credit facility provides for borrowings at an interest rate based on the Sterling Overnight Index Average Rate. The credit facility may be collateralized by cash and eligible securities, including U.S. Treasury securities. As of September 30, 2026, the credit facility was fully collateralized. As of September 30, 2026, there were no borrowed amounts outstanding under the credit facility.

In April 2025, we and certain of our traditional U.S. life insurance subsidiaries, Unum Life Insurance Company of America (Unum America), Provident, and Colonial Life & Accident Insurance Company, amended and restated the terms of our existing credit agreement providing for a five-year $500.0 million senior unsecured revolving credit facility with a syndicate of lenders. The revolving credit facility, which was previously set to expire in 2027, was extended through April 2030. We may request that the lenders’ aggregate commitments of $500.0 million under the facility be increased by up to an additional $200.0 million. Other of our domestic wholly-owned subsidiaries are permitted to join the credit facility as borrowers, subject to certain conditions. Any obligation of a subsidiary under the credit facility is subject to an unconditional guarantee by Unum Group. At September 30, 2026, there were no borrowed amounts outstanding under the revolving credit facility and letters of credit totaling $1.3 million had been issued.

Borrowings under the credit facilities are subject to financial covenants, negative covenants, and events of default that are customary. The credit facilities include financial covenants based on our leverage ratio and consolidated net worth as well as covenants that limit subsidiary indebtedness and require minimum capital levels.

Junior Subordinated Debt Securities

During the first quarter of 2026, we purchased and retired $7.7 million aggregate principal amount of our 6.250% junior subordinated debt securities issued in 2018 and due 2058.

Income Tax Disclosure

Income Tax

During the third quarter of 2026, we recognized a tax benefit of $188.2 million from the release of unrecognized tax benefits related to a policyholder reserves position taken on our 2017 return following the completion of an Internal Revenue Service exam. The benefit reflects the release of the related unrecognized tax benefit liability of $112.9 million and accrued interest of $75.3 million.

During the third quarter of 2026, we established a valuation allowance that increased income tax expense by $176.2 million related to our deferred tax assets on capital losses, reflecting a change in our assessment of the realizability of these deferred tax assets. Based on expected capital losses associated with the 2026 Fortitude Re reinsurance transaction, we believe it is more likely than not that we will not be able to realize the benefit of these capital losses against future capital gains within the statutory carryforward period.

Allowance for Expected Credit Losses on Premiums Receivable

Allowance for Expected Credit Losses on Premiums Receivable

At September 30, 2026, June 30, 2026, and December 31, 2025, the allowance for expected credit losses on premiums receivable was $26.7 million, $26.9 million, and $26.1 million, respectively, on gross premiums receivable of $737.6 million, $746.7 million, and $579.5 million, respectively. The allowance for expected credit losses was generally consistent during these periods.

At September 30, 2025, June 30, 2025, and December 31, 2024, the allowance for expected credit losses on premiums receivable was $28.0 million, $27.6 million, and $26.8 million, respectively, on gross premiums receivable of $598.9 million, $691.7 million, and $584.1 million, respectively. The allowance for expected credit losses was generally consistent at September 30, 2025 compared to June 30, 2025. The increase in the allowance of $1.2 million during the nine months ended September 30, 2025 was driven by an increase in the age of premium receivable and an increase in gross premiums receivable.

Reinsurance

2026 Closed Block Long-Term Care Reinsurance Transaction

In July 2026, Unum America entered into a master transaction agreement with Fortitude Reinsurance Company Ltd. (Fortitude Re) which resulted in the execution of a coinsurance agreement in November 2026.

This reinsurance agreement reinsures a portion of our Closed Block individual long-term care policies on a coinsurance basis to Fortitude Re effective April 2026. The reinsurance agreement represents approximately 28 percent of total Closed Block long-term care future policy benefits as of March 31, 2026. Upon closing the transaction in November 2026, we transferred fixed maturity securities and cash with a fair value of $5,500.7 million. A final settlement is expected prior to the end of the first quarter of 2027. Fortitude Re intends to retrocede biometric risk on the reinsured block to a highly rated global reinsurer (the Retrocessionaire).

Additionally, at the closing of the transaction, Provident entered into an agreement with the Retrocessionaire whereby Provident provides an experience volatility cover for the difference between actual and expected claim experience, subject to a maximum payment of $125.0 million (in net present value terms). Payment obligations will be settled every five years and are secured by a trust account to be funded at all times with the remaining possible payment by Provident. Provident provided the experience volatility cover in exchange for a payment from the Retrocessionaire of $5.0 million at the closing of the reinsurance transaction. The experience volatility cover is accounted for under the deposit method.

Immediately prior to entering into the reinsurance agreement with Fortitude Re, Unum America recaptured the Closed Block individual long-term care business from Fairwind Insurance Company (Fairwind), an affiliated captive reinsurer.

2025 Closed Block Long-Term Care and Unum US Individual Disability Reinsurance Transaction

In February 2025, Unum America entered into a master transaction agreement with Fortitude Re which resulted in the execution of a coinsurance agreement during July 2025. This reinsurance agreement reinsures a portion of our Closed Block long-term care business and a portion of our Unum US individual disability business on a coinsurance basis to Fortitude Re effective January 2025.

Upon closing the transaction in July 2025, we transferred to Fortitude Re $953.5 million of cash as well as fixed maturity securities with a fair value totaling $3,230.1 million and accrued investment income of $47.1 million. After consideration of the final settlement, the final ceding commission related to this transaction was $442.3 million.

As a result of this reinsurance agreement, we recognized the following:

•Net realized investment loss totaling $46.8 million during the year ended December 31, 2025.

•Reinsurance recoverable of $3,620.5 million comprised of ceded reserves of $3,315.2 million related to the Closed Block long-term care product line and $305.3 million related to the Unum US individual disability product line.

•Cost of reinsurance of $848.2 million related to the Closed Block long-term care product line and a deferred gain on reinsurance related to the Unum US individual disability product line of $145.9 million.

•Write-off of deferred acquisition costs related to the Unum US individual disability product line of $100.3 million which is included as a component of deferred gain on reinsurance.

In July 2025, immediately prior to entering into the reinsurance agreement with Fortitude Re, Unum America recaptured the aforementioned Closed Block long-term care business from Fairwind and assumed the aforementioned Unum US individual disability business from Provident.

Quantitative Information Regarding Significant Unobservable Inputs

The table below provides quantitative information regarding the significant unobservable inputs used in Level 3 fair value measurements derived from internal models. Unobservable inputs for fixed maturity securities are weighted by the fair value of the securities. Certain securities classified as Level 3 are excluded from the table below due to limitations in our ability to obtain the underlying inputs used by external pricing sources.

(Fortitude Re). Our investment gains and losses on fixed maturity securities for the third quarter and first nine months of 2025 were driven primarily by the Closed Block long-term care and Unum US individual disability reinsurance transaction (2025 Fortitude Re reinsurance transaction) which resulted in a net gain of $137.6 million in the third quarter of 2025 and a net loss of $46.8 million in the first nine months of 2025. We also realized a $19.1 million loss on sales of fixed maturity securities related to the funding of an extraordinary dividend from a wholly owned insurance subsidiary to Unum Group in the first nine months of 2025.

Common stock repurchases, which are accounted for using the cost method and classified as treasury stock until otherwise retired, were as follows:

1For the nine months ended September 30, 2025, includes 0.7 million shares related to the settlement of the November 2024 accelerated share repurchase agreement (ASR) which occurred in February 2025.

2Includes a de minimis amount and $0.3 million of commissions for the three and nine months ended September 30, 2026, respectively, and $0.9 million and $1.8 million of commissions for the three and nine months ended September 30, 2025. Also includes $2.0 million and $7.7 million of excise tax for the three and nine months ended September 30, 2026, respectively, and $2.4 million and $7.4 million of excise tax for the three and nine months ended September 30, 2025, respectively.

As a part of our share repurchase program, we periodically enter into accelerated share repurchase agreements. Under the terms of these agreements, we make a prepayment to a financial counterparty for which we receive an initial delivery of approximately 75 percent of the total Unum Group common stock to be delivered under the agreement. We simultaneously enter into a forward contract indexed to the price of Unum Group common stock, which subjects the transactions to a future price adjustment. Under the terms of the agreements, we are to receive, or be required to pay, a price adjustment based on the volume weighted average price of Unum Group common stock during the term of the agreement, less a discount. Any price adjustment payable to us is settled in shares of Unum Group common stock. Any price adjustment we would be required to pay may be settled in either cash or common stock at our option. In November 2024, we paid $321.0 million to a financial counterparty as a part of an accelerated share repurchase agreement. We received an initial delivery of 3.8 million shares of our common stock. The final price adjustment settlement, along with the delivery of the remaining shares, occurred in February 2025, resulting in the delivery to us of 0.7 million additional shares. As a result of the final settlement occurring subsequent to December 31, 2024, we recorded a decrease of $80.3 million to additional paid-in capital within stockholders' equity on our

consolidated balance sheet for the value of the shares held back by the counterparty as of December 31, 2024, which was reclassified to treasury stock in the first quarter of 2025 in connection with the final settlement of the agreement.

[1] 1During the three and nine months ended September 30, 2026 we recognized $754.4 million of realized losses based on the intent to dispose of fixed maturity securities with a fair value of $4,232.3 million related to the 2026 reinsurance transaction with Fortitude Reinsurance Company Ltd. (Fortitude Re). Our investment gains and losses on fixed maturity securities for the third quarter and first nine months of 2025 were driven primarily by the Closed Block long-term care and Unum US individual disability reinsurance transaction (2025 Fortitude Re reinsurance transaction) which resulted in a net gain of $137.6 million in the third quarter of 2025 and a net loss of $46.8 million in the first nine months of 2025. We also realized a $19.1 million loss on sales of fixed maturity securities related to the funding of an extraordinary dividend from a wholly owned insurance subsidiary to Unum Group in the first nine months of 2025.
