•Net income of $395.2 million ($2.04 per diluted common share) for the first quarter of 2024; after-tax adjusted operating income was $409.9 million ($2.12 per diluted common share).

•Results reflect a growing top-line with core operations premium growth of 6.6 percent on a constant currency basis, and robust margins highlighted by group disability, group life and AD&D, and supplemental and voluntary.

•Strong balance sheet with holding company liquidity of $1.4 billion and weighted average risk-based capital ratio of approximately 440 percent, well in excess of targets; statutory operating earnings of $350.5 million.

•Increased capital deployment to shareholders through accelerated pace of share repurchases and increase in common stock dividend of 15 percent, beginning with the dividend to be paid in the third quarter of 2024.

•Book value per common share of $53.38 grew 13.9 percent over the year-ago quarter; book value per common share excluding accumulated other comprehensive income (AOCI) of $68.73 grew 9.3 percent over the year-ago quarter.

CHATTANOOGA, Tenn. (April 30, 2024) - Unum Group (NYSE: UNM) today reported net income of $395.2 million ($2.04 per diluted common share) for the first quarter of 2024, compared to net income of $358.3 million ($1.80 per diluted common share) for the first quarter of 2023.

Included in net income for the first quarter of 2024 are the after-tax amortization of the cost of reinsurance of $8.2 million ($0.04 per diluted common share), the after-tax impact of non-contemporaneous reinsurance of $5.7 million ($0.04 per diluted common share), and a net after-tax investment loss on the Company’s investment portfolio of $0.8 million (de minimis amount per diluted common share). Included in net income for the first quarter of 2023 are the after-tax amortization of the cost of reinsurance of $8.7 million ($0.04 per diluted common share), the after-tax impact of non-contemporaneous reinsurance of $5.7 million ($0.03 per diluted common share), and a net after-tax investment gain on the Company’s investment portfolio of $0.1 million (de minimis amount per diluted common share). Excluding the items above, after-tax adjusted operating income was $409.9 million ($2.12 per diluted common share) in the first quarter of 2024, compared to $372.6 million ($1.87 per diluted common share) in the first quarter of 2023.

“We are very pleased with our first quarter performance, which represents a very strong start to the year,” said Richard P. McKenney, president and chief executive officer. “Our businesses generated healthy core premium growth and delivered particularly strong performance overall in our Group Disability and Group Life businesses. We also executed against our capital deployment strategy, returning additional capital to our shareholders through increased share repurchases and approval of a 15 percent increase to our dividend. Looking ahead, we are well positioned for a strong 2024. Market conditions remain favorable, and we continue to see strong demand for our digital capabilities. Coupled with the strength of our balance sheet, we are well positioned to continue executing on our growth strategy and creating value for our shareholders.”

RESULTS BY SEGMENT

We measure and analyze our segment performance on the basis of "adjusted operating income" or "adjusted operating loss", which differ from income before income tax as presented in our consolidated statements of income due to the exclusion of investment gains and losses, amortization of cost of reinsurance, the impact of non-contemporaneous reinsurance, and reserve assumption updates. Investment gains or losses primarily include realized investment gains or losses, expected investment credit losses, and gains or losses on derivatives. Reserve assumption updates may result in increases or decreases to earnings. These performance measures are in accordance with GAAP guidance for segment reporting, but they should not be viewed as a substitute for income before income tax, net income or net loss.

Unum US Segment

Unum US reported adjusted operating income of $385.2 million in the first quarter of 2024, an increase of 23.3 percent from $312.5 million in the first quarter of 2023. Premium income increased 6.1 percent to $1,707.4 million in the first quarter of 2024, compared to $1,609.6 million in the first quarter of 2023. Net investment income was $157.0 million in the first quarter of 2024, which was generally consistent to the $157.3 million in the first quarter of 2023.

Within the Unum US operating segment, the group disability line of business reported a 13.1 percent increase in adjusted operating income to $164.8 million in the first quarter of 2024, compared to $145.7 million in the first quarter of 2023. Premium income for the group disability line of business increased 4.7 percent to $779.8 million in the first quarter of 2024, compared to $745.0 million in the first quarter of 2023, driven by favorable persistency and higher prior period sales. Net investment income decreased 4.1 percent to $77.8 million in the first quarter of 2024, compared to $81.1 million in the first quarter of 2023, due to a lower level of invested assets, partially offset by an increase in the yield on invested assets. The benefit ratio for the first quarter of 2024 was 57.5 percent, compared to 60.0 percent in the first quarter of 2023, due primarily to favorable claims incidence in our group long-term and short-term disability product lines. Group long-term disability sales were $54.6 million in the first quarter of 2024, an increase of 1.3 percent from $53.9 million in the first quarter of 2023. Group short-term disability sales were $35.9 million in the first quarter of 2024, a decrease of 3.0 percent from $37.0 million in the first quarter of 2023. Persistency in the group long-term disability product line was 93.1 percent for the first three months of 2024, compared to 90.6 percent for the first three months of 2023.

The group life and accidental death and dismemberment line of business reported a 96.5 percent increase in adjusted operating income to $78.8 million in the first quarter of 2024, compared to $40.1 million in the first quarter of 2023. Premium income for this line of business increased 7.0 percent to $488.4 million in the first quarter of 2024, compared to the $456.6 million in the first quarter of 2023 due primarily to favorable persistency and higher prior period sales. Net investment income was $22.0 million in the first quarter of 2024, which was generally consistent with $22.6 million in the first quarter of 2023. The benefit ratio in the first quarter of 2024 was 68.2 percent, compared to 75.0 percent in the first quarter of 2023 due primarily to favorable incidence in the group life product line. Sales of group life and accidental death and dismemberment products increased 9.5 percent in the first quarter of 2024 to $42.8 million, compared to $39.1 million in the first quarter of 2023. Persistency in the group life product line was 91.7 percent for the first three months of 2024, compared to 88.8 percent for the first three months of 2023. Persistency in the accidental death and dismemberment product line was 91.4 percent for the first three months of 2024, compared to 87.6 percent for the first three months of 2023.

The supplemental and voluntary line of business reported an increase of 11.8 percent in adjusted operating income to $141.6 million in the first quarter of 2024, compared to $126.7 million in the first quarter of 2023. Premium income for the supplemental and voluntary line of business increased 7.6 percent to $439.2 million in the first quarter of 2024, compared to $408.0 million in the first quarter of 2023, due to continued impacts from the partial recapture of a previously ceded block of business in the individual disability product line as well as higher prior period sales and favorable persistency. Net investment income increased 6.7 percent to $57.2 million in the first quarter of 2024, compared to $53.6 million in the first quarter of 2023, due primarily to an increase in the yield on invested assets. The benefit ratio for the voluntary benefits product line was 33.8 percent in the first quarter of 2024, compared to 36.0 percent in the first quarter of 2023, driven primarily by the critical illness product line. The benefit ratio for the

individual disability product line was 41.1 percent for the first quarter of 2024, compared to 45.3 percent in the first quarter of 2023, due primarily to favorable recoveries. The benefit ratio for the dental and vision product line was 72.4 percent for the first quarter of 2024, compared to 80.2 percent in the first quarter of 2023, due primarily to lower claims incidence and average claim size. Relative to the first quarter of 2023, sales in the voluntary benefits product line decreased 2.7 percent in the first quarter of 2024 to $107.9 million. Sales in the individual disability product line decreased 20.6 percent to $21.2 million in the first quarter of 2024.

Premium income increased 22.9 percent to $231.7 million in the first quarter of 2024, compared to $188.6 million in the first quarter of 2023.

The Unum UK line of business reported adjusted operating income, in local currency, of £28.2 million in the first quarter of 2024, a decrease of 9.0 percent from £31.0 million in the first quarter of 2023. Premium income was £154.0 million in the first quarter of 2024, an increase of 15.0 percent from £133.9 million in the first quarter of 2023, due primarily to in-force block growth. Net investment income was £18.4 million in the first quarter of 2024, a decrease of 22.4 percent from £23.7 million in the first quarter of 2023, due primarily to lower investment income from inflation index-linked bonds. The benefit ratio was 68.1 percent in the first quarter of 2024, compared to 68.5 percent in the first quarter of 2023, due to lower mortality in the group life product line and lower inflation-linked experience in benefits, partially offset by unfavorable experience in the supplemental product line due to higher claims incidence. Sales decreased 3.3 percent to £29.6 million in the first quarter of 2024, compared to £30.6 million in the first quarter of 2023. Persistency in the group long-term disability product line was 92.7 percent for the first three months of 2024, compared to 90.1 percent for the first three months of 2023.

Colonial Life Segment

Colonial Life reported adjusted operating income of $113.7 million in the first quarter of 2024, a 21.1 percent increase compared to $93.9 million in the first quarter of 2023. Premium income increased 4.1 percent to $446.9 million in the first quarter of 2024, compared to $429.5 million in the first quarter of 2023, due to higher prior period sales and favorable persistency. Net investment income increased to $39.3 million in the first quarter of 2024, compared to $37.3 million in the first quarter of 2023, due to an increase in the yield on invested assets and an increase in the level of invested assets. The benefit ratio was 48.6 percent in the first quarter of 2024, compared to 53.0 percent in the first quarter of 2023, primarily due to lower benefits in the cancer and critical illness and accident, sickness, and disability product lines. Sales decreased 3.6 percent to $103.0 million in the first quarter of 2024, compared to $106.8 million in the first quarter of 2023. Persistency in the Colonial Life segment was 78.4 percent for the first three months of 2024, compared to 77.3 percent for the first three months of 2023.

Closed Block Segment

The Closed Block segment reported adjusted operating income of $24.3 million in the first quarter of 2024, which excludes the amortization of cost of reinsurance of $10.4 million and the impact of non-contemporaneous reinsurance of $7.2 million related to the Closed Block individual disability reinsurance transaction, compared to $58.2 million in the first quarter of 2023, which excludes the amortization of cost of reinsurance of $11.0 million and the impact of non-contemporaneous reinsurance of $7.3 million related to the Closed Block individual disability reinsurance transaction. Premium income for this segment is largely driven by our long-term care product line, and in the first quarter of 2024, premium income for long-term care was generally consistent with the same period of 2023. Net investment income increased 6.2 percent to $273.1 million in the first quarter of 2024, compared to $257.2 million in the first quarter of 2023, primarily due to an increase in the level of invested assets and higher miscellaneous investment income, primarily related to larger increases in the net asset value on our private equity partnerships.

The net premium ratio for the long-term care product line increased to 93.8 percent at March 31, 2024 from 85.3 percent at March 31, 2023, due primarily to the impacts of the reserve assumption updates in the third quarter of 2023. Benefits were unfavorable during the first quarter of 2024 relative to the same period of 2023 driven primarily by the increase in current period benefit expense resulting from the higher net premium ratio. Compared to December 31, 2023, the net premium ratio increased from 93.5 percent to 93.8 percent due to the impact of a large case termination in the first quarter. Overall claim experience was relatively in line with our communicated guidance of short-term elevated experience.

Corporate Segment

The Corporate segment reported an adjusted operating loss of $46.1 million in the first quarter of 2024, compared to an adjusted operating loss of $33.5 million in the first quarter of 2023, due primarily to a decrease in net investment income, driven by increased allocation to our lines of business, and higher retirement plan expenses.

NON-GAAP 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 GAAP. We believe the following non-GAAP financial measures are better performance measures and better indicators of the revenue and profitability and underlying trends in our business:

•After-tax adjusted operating income or loss, which excludes investment gains or losses, amortization of the cost of reinsurance, non-contemporaneous reinsurance, and reserve assumption updates, as well as certain other items, as applicable;

•Book value per common share, which is calculated excluding AOCI.

Investment gains or losses primarily include realized investment gains or losses, expected investment credit losses, and gains or losses on derivatives. We believe after-tax adjusted operating income is a better performance measure and better indicator of the profitability and underlying trends in our business. Book value per common share excluding AOCI provides a more comparable and consistent view of our results, as AOCI tends to fluctuate depending on market conditions and general economic trends.

Cash flow assumptions used to calculate our liability for future policy benefits are reviewed at least annually and updated, as needed, with the resulting impact reflected in net income. While the effects of these assumption updates are recorded in the reporting period in which the review is completed, these updates reflect experience emergence and changes to expectations spanning multiple periods. We believe that by excluding the impact of reserve assumption updates we are providing a more comparable and consistent view of our quarterly results.

We exited a substantial portion of our Closed Block individual disability product line through the two phases of the reinsurance transaction that were executed in December 2020 and March 2021. As a result, we exclude the amortization of the cost of reinsurance that we recognized upon the exit of the business related to the policies on claim status as well as the impact of non-contemporaneous reinsurance that resulted from the adoption of Accounting Standards Update 2018-12 (ASU 2018-12). Due to the execution of the second phase of the reinsurance transaction occurring after January 1, 2021, the transition date of ASU 2018-12, in accordance with the provisions of the ASU related to non-contemporaneous reinsurance, we were required to establish the ceded reserves using an upper-medium grade fixed-income instrument as of the reinsurance transaction date in March 2021, which resulted in higher ceded reserves compared to that which was reported historically. However, the direct reserves for the block reinsured in the second phase were calculated using the original discount rate utilized as of the transition date. Both the direct and ceded reserves are then remeasured at each reporting period using a current discount rate reflective of an upper-medium grade fixed-income instrument, with the changes recognized in other comprehensive income (loss). While the total equity impact is neutral, the different original discount rates utilized for direct and ceded reserves result in disproportionate earnings impacts. The impact of non-contemporaneous reinsurance will fluctuate depending on the magnitude of reserve changes during the period. We believe that the exclusion of these items provides a better view of our results from our ongoing businesses.

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.

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 “Risk Factors” of our annual report on Form 10-K for the year ended December 31, 2023.

Unum Group Financial Results by Segment

We measure and analyze our segment performance on the basis of "adjusted operating revenue" and "adjusted operating income" or "adjusted operating loss", which differ from total revenue and income before income tax as presented in our consolidated statements of income due to the exclusion of investment gains or losses, amortization of the cost of reinsurance, non-contemporaneous reinsurance, and reserve assumption updates, as well as certain other items as specified in the following pages. Investment gains or losses primarily include realized investment gains or losses, expected investment credit losses, and gains or losses on derivatives. 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.

Appendix to Statistical Supplement

2024 Significant Items:

•None.

2023 Significant Items:

•Third quarter of 2023 reserve assumption updates resulting in a net reserve increase of $177.2 million before tax, or $139.3 million after tax.

•In 2018, the Financial Accounting Standards Board issued ASU 2018-12, “Targeted Improvements to the Accounting for Long-Duration Contracts”. This update significantly amended the accounting and disclosure requirements for long-duration insurance contracts. The update was effective for periods beginning January 1, 2023. We adopted this guidance effective January 1, 2023 using the modified retrospective approach with changes applied as of January 1, 2021, also referred to as the transition date.

2022 Significant Items

•Third quarter of 2022 reserve assumption updates resulting in a net reserve reduction of $243.3 million before tax, or $192.1 million after tax.

Appendix to Statistical Supplement - Continued

Non-GAAP Financial Measures

We analyze our performance using non-GAAP financial measures which exclude or include amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. We believe the following non-GAAP financial measures are better performance measures and better indicators of the revenue and profitability and underlying trends in our business:

•Consolidated adjusted operating revenue, which excludes investment gains or losses;

•Adjusted operating return on equity, which is calculated using after-tax adjusted operating income or loss and excludes from equity the unrealized gain or loss on securities, the effect of change in discount rate assumptions on the liability for future policy benefits, and net gain or loss on derivatives;

•Leverage ratio, which excludes the unrealized gain or loss on securities, the effect of change in discount rate assumptions on the liability for future policy benefits, and net gain or loss on derivatives; and

•Book value per common share, which is calculated excluding accumulated other comprehensive income (loss) (AOCI).

Investment gains or losses primarily include realized investment gains or losses, expected investment credit losses, and gains or losses on derivatives. Investment gains or losses and unrealized gains or losses on securities depend on market conditions and do not necessarily relate to decisions regarding the underlying business of our Company. Leverage ratio and book value per common share excluding certain components of AOCI, certain of which tend to fluctuate depending on market conditions and general economic trends, are important measures.

We exited a substantial portion of our Closed Block individual disability product line through the two phases of the reinsurance transaction that were executed in December 2020 and March 2021. As a result, we exclude the amortization of the cost of reinsurance that we recognized upon the exit of the business related to the policies on claim status as well as the impact of non-contemporaneous reinsurance that resulted from the adoption of ASU 2018-12. Due to the execution of the second phase of the reinsurance transaction occurring after January 1, 2021, the transition date of ASU 2018-12, in accordance with the provisions of the ASU related to non-contemporaneous reinsurance, we were required to establish the ceded reserves using an upper-medium grade fixed-income instrument as of the reinsurance transaction date in March 2021 which resulted in higher ceded reserves compared to that which was reported historically. However, the direct reserves for the block reinsured in the second phase were calculated using the original discount rate utilized as of the transition date. Both the direct and ceded reserves are then remeasured at each reporting period using a current discount rate reflective of an upper-medium grade fixed-income instrument, with the changes recognized in other comprehensive income (loss). While the total equity impact is neutral, the different original discount rates utilized for direct and ceded reserves result in disproportionate earnings impacts. The impact of non-contemporaneous reinsurance will fluctuate depending on the magnitude of reserve changes during the period. We believe that the exclusion of these items provides a better view of our results from our ongoing businesses.
