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.

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 June 30, 2026, approximately 23.3 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 76.7 percent of our fixed maturity securities were valued based on non-binding quotes or other observable and unobservable inputs, as discussed below:

• 58.1 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.
• 17.1 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.
• 1.5 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 June 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.

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 $3,360.3 million and $3,353.8 million as of June 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.

Policyholders' Account Balances: Funding agreements which 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.

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 June 30, 2026.

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 June 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 June 30, 2026, we held 921 individual investment-grade fixed maturity securities and 55 individual below-investment-grade fixed maturity securities that were in an unrealized loss position, of which 744 investment-grade fixed maturity securities and 24 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 six months ended June 30, 2026.

At June 30, 2026, we had commitments of $92.4 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 June 30, 2026, the carrying amount of our variable interest entity investments not consolidated in our financial statements, which are primarily private equity partnerships, totaled $1,425.1 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. Our general policy for newly issued loans is to have a debt service coverage ratio greater than 1.25 times on a normalized 25 year amortization period. 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 $2,087.7 million and $2,125.4 million at June 30, 2026 and December 31, 2025, respectively. The allowance for expected credit losses was $16.0 million and $15.9 million at June 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 June 30, 2026 and December 31, 2025.

The carrying amount of mortgage loans by property type and geographic region are presented below.

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 six months ended June 30, 2026, no commercial mortgage loans were modified for borrowers experiencing financial difficulties. During the six months ended June 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 six months ended June 30, 2026 and 2025, all commercial loans which were previously modified for borrowers experiencing financial difficulties were current.

As of June 30, 2026 and December 31, 2025, we held no specifically identified impaired mortgage loans. There were no commercial mortgage loans past due as to principal and/or interest payments as of June 30, 2026 and December 31, 2025.

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

At June 30, 2026, we had $25.5 million of commitments to fund commercial mortgage loans. Consistent with how we determine the estimate of current expected credit losses for our funded mortgage loans each period, we estimate expected credit losses for loans that have not been funded but we are committed to fund at the end of each period. At June 30, 2026, we had $0.1 million of expected credit losses related to unfunded commitments on our consolidated balance sheets. At December 31, 2025, we had no expected credit losses related to unfunded commitments on our consolidated balance sheets.

Investment Real Estate

Our real estate held for the production of income balance was $62.7 million and $41.7 million at June 30, 2026 and December 31, 2025, respectively, and the associated accumulated depreciation was $202.3 million and $130.1 million at June 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 $1.6 million and $41.9 million at June 30, 2026 and December 31, 2025 and the associated accumulated depreciation was $3.5 million and $57.5 million at June 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 June 30, 2026, the carrying amount of fixed maturity securities loaned to third parties under our securities lending program was $100.8 million, for which we received collateral in the form of cash and securities of $67.6 million and $37.5 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 June 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, collateral posted, and advances received are as follows:

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 June 30, 2026, we did not have any amounts outstanding under the FABL program.

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.

Note 5 - Derivative Financial Instruments

Purpose of Derivatives

We are exposed to certain risks relating to our ongoing business operations. 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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) - Continued

Unum Group and Subsidiaries

June 30, 2026

Note 5 - Derivative Financial Instruments - Continued

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, and credit 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 and hedge the economic risk from credit spread and interest rate duration related to certain cash and cash equivalent amounts. A total return swap is an agreement in which we pay a floating rate of interest to the counterparty and receive the total return on a portfolio of mutual funds and/or exchange traded funds. These swaps are cash settled on the last day of every month and the notional is re-established each month based on plan participant actions or cash settled at maturity.

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 June 30, 2026, we had $1.1 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.

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 $223.0 million and $269.7 million at June 30, 2026 and December 31, 2025, respectively.

Cash Flow Hedges

As of June 30, 2026 and December 31, 2025, we had $112.6 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 June 30, 2026 and December 31, 2025, we had $2,417.0 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 June 30, 2026, we expect to amortize approximately $0.9 million of net deferred gains 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 June 30, 2026, we are hedging the variability of future cash flows associated with forecasted transactions through the year 2053.

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 six months ended June 30, 2026, $(12.1) million and $(7.4) 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 six months ended June 30, 2025, $(2.3) million and $24.9 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 June 30, 2026 and December 31, 2025, we held $89.0 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 June 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 June 30, 2026 and December 31, 2025, we held $171.8 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.

As of June 30, 2026 and December 31, 2025, we held no total return swap contracts to mitigate the economic risk from credit spreads and interest rate duration related to certain cash and cash equivalent amounts. During the first quarter of 2025, we entered into a total return swap contract with a notional amount of $700.0 million. This derivative was an economic hedge not designated as a hedging instrument, and changes in fair value were reported in realized gains or losses in our income statement. Expenses and dividend payments were reported in earnings as a component of net investment income. The total return swap was unwound and settled for cash in the second quarter of 2025.

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. 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 5.3 percent at June 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 5.2 percent at June 30, 2025 and 5.3 percent at December 31, 2024 with the decrease due primarily to a decrease in U.S. Treasury rates.

Actual variance from expected experience during the first six months of 2026 and 2025 was due primarily to the Closed Block long-term care, Unum US group disability, and Unum US group life and accidental death and dismemberment product lines. Also contributing to the comparison for the first six months of 2025 was the Closed Block all other product line. During the first six months of 2026 the variance in the Closed Block long-term care product line was primarily due to higher group long-term care policy terminations and higher than expected claim incidence. During the first six months of 2025, the variance in the Closed Block long-term care product line was driven primarily by higher than expected claim incidence, partially offset by higher than expected mortality experience. During the first six months of 2026 and 2025, the variance in the Unum US group disability product line was driven primarily by higher than expected claim resolutions driven by recoveries. During the first six months of 2026 and 2025, the variance in the Unum US group life and accidental death and dismemberment product line was driven primarily by lower than expected incidence. During the first six months of 2025 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 line.

For the six months ended June 30, 2026 and 2025, there were certain cohorts within the Closed Block segment, related to our long-term care product line, for which net premiums exceed gross premiums, which resulted in a $63.6 million reduction to income before income tax for the six months ended June 30, 2026 and resulted in a $26.4 million reduction to income before income tax for the six months ended June 30, 2025. There were also certain cohorts within the Colonial Life segment, related to our cancer and critical illness product line, for which net premiums exceeded gross premiums, which had an immaterial impact to income before income tax for the six months ended June 30, 2026 and 2025. There were no other product lines with cohorts for which net premiums exceeded gross premiums for the six months ended June 30, 2026 or 2025.
