CHATTANOOGA, Tenn. (February 5, 2026) - Unum Group (NYSE: UNM) today reported net income of $174.1 million ($1.04 per diluted common share) for the fourth quarter of 2025, compared to net income of $348.7 million ($1.92 per diluted common share) for the fourth quarter of 2024.
Included in net income for the fourth quarter of 2025 is the after-tax amortization of the cost of reinsurance of $38.6 million ($0.23 per diluted common share), the after-tax amortization of the deferred gain on reinsurance of $3.5 million ($0.02 per diluted common share), the after-tax impact of non-contemporaneous reinsurance of $7.9 million ($0.05 per diluted common share), the after-tax impact of the settlement loss on the U.S. pension plan annuity purchase of $82.0 million ($0.49 per diluted common share), the after-tax impact of the accelerated charitable contribution of $15.8 million ($0.09 per diluted common share), as well as a net after-tax investment loss on the Company’s investment portfolio of $7.4 million ($0.04 per diluted common share).

“In 2025 we executed on our strategy, delivered for our customers, and drove disciplined operational performance. Additionally, we materially improved the risk profile of the Closed Block, and returned significant capital to our shareholders,” said Richard P. McKenney, president and chief executive officer. “We also continued to invest in our digital capabilities, reinforcing our differentiated solutions and driving solid premium and sales growth. While benefits expenses were higher than expected across the portfolio, our core operations continue to deliver strong returns. With robust capital levels, and a clear strategic focus, we remain committed to disciplined execution and confident in our ability to drive growth and create lasting 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 or losses, certain impacts from reinsurance transactions, reserve assumption updates, and certain other items as specified in the reconciliations below. Investment gains or losses primarily include realized investment gains or losses, expected investment credit losses, impairment 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 U.S. generally accepted accounting principles (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 a decrease of 13.1 percent in adjusted operating income to $289.7 million in the fourth quarter of 2025, which excludes the amortization of the deferred gain on reinsurance of $4.4 million offset by the impact of non-contemporaneous reinsurance of $0.6 million, compared to $333.2 million in the fourth quarter of 2024. Premium income for the segment increased 1.6 percent to $1,748.6 million in the fourth quarter of 2025, compared to premium income of $1,721.4 million in the fourth quarter of 2024. Net investment income for the segment decreased 5.0 percent to $148.3 million in the fourth quarter of 2025, compared to $156.1 million in the fourth quarter of 2024.

Premium income for the group disability line of business decreased 1.8 percent to $784.4 million in the fourth quarter of 2025, compared to $799.1 million in the fourth quarter of 2024, driven by the expected run-off in medical stop-loss premium, partially offset by an increase in premium income due to sales. Net investment income decreased 5.5 percent to $72.2 million in the fourth quarter of 2025, compared to $76.4 million in the fourth quarter of 2024, primarily driven by a decrease in the level of invested assets and a decrease in the yield on invested assets. The benefit ratio for the fourth quarter of 2025 was 64.2 percent, compared to 60.4 percent in the fourth quarter of 2024, due primarily to claim size in our group long-term and group short-term disability product lines and lower claim resolutions driven by mortality in group long term disability. Group long-term disability sales were $127.2 million in the fourth quarter of 2025, a decrease of 17.7 percent from $154.5 million in the fourth quarter of 2024. Group short-term disability sales were $177.9 million in the fourth quarter of 2025, an increase of 45.3 percent from $122.4 million in the fourth quarter of 2024.

Premium income for this line of business increased 4.5 percent to $515.9 million in the fourth quarter of 2025, compared to $493.6 million in the fourth quarter of 2024, driven primarily by sales and in-force block growth. Net investment income decreased 2.8 percent to $21.1 million in the fourth quarter of 2025, compared to $21.7 million in the fourth quarter of 2024, primarily driven by a lower level of invested assets. The benefit ratio in the fourth quarter of 2025 was 64.8 percent, compared to 66.7 percent in the fourth quarter of 2024, due primarily to favorable incidence, partially offset by higher average claim size in in our group life product line. Sales of group life and accidental death and dismemberment products decreased 1.7 percent in the fourth quarter of 2025 to $206.8 million, compared to $210.3 million in the fourth quarter of 2024. Persistency in the group life product line was 90.2 percent for full year 2025, compared to 92.0 percent for full year 2024. Persistency in the accidental death and dismemberment product line was 89.1 percent for full year 2025, compared to 91.2 percent for full year 2024.
The supplemental and voluntary line of business reported a decrease of 8.2 percent in adjusted operating income to $95.5 million in the fourth quarter of 2025, which excludes the amortization of the deferred gain on reinsurance of $4.4 million partially offset by the impact of non-contemporaneous reinsurance of $0.6 million, compared to $104.0 million in the fourth quarter of 2024. Premium income for the supplemental and voluntary line of business increased 4.6 percent to $448.3 million in the fourth quarter of 2025, compared to $428.7 million in the fourth quarter of 2024, due to the continued

impacts from the recapture of a previously ceded block of business in the individual disability product line in the first quarter of 2025, higher prior period sales in the voluntary benefits product line, and favorable persistency in the voluntary benefits and dental and vision product lines, partially offset by the impact of ceding a portion of the individual disability product line as a part of the Closed Block long-term care and Unum US individual disability reinsurance transaction (Fortitude Re reinsurance transaction). Net investment income decreased 5.2 percent to $55.0 million in the fourth quarter of 2025, compared to $58.0 million in the fourth quarter of 2024, driven primarily by a decrease in the level of invested assets. The benefit ratio for the voluntary benefits product line was 48.5 percent in the fourth quarter of 2025, compared to 47.3 percent for the fourth quarter of 2024, due primarily to unfavorable benefit experience in the hospital indemnity, accident, and critical illness products, partially offset by favorable benefits experience in the life product line.

Net investment income was £23.3 million in the fourth quarter of 2025, a decrease of 4.5 percent from £24.4 million in the fourth quarter of 2024, primarily due to a decrease in the level of invested assets and lower income from inflation index-linked bonds, partially offset by an increase in the yield on invested assets. The benefit ratio in the fourth quarter of 2025 was 77.9 percent, compared to 72.1 percent in the fourth quarter of 2024, due to unfavorable claim resolutions and higher incidence in the group long-term disability product line, partially offset by lower claim incidence in the group life product line. Sales increased 20.4 percent to £25.4 million in the fourth quarter of 2025, compared to £21.1 million in the fourth quarter of 2024.

The benefit ratio was 48.3 percent in the fourth quarter of 2025, compared to 46.8 percent in the fourth quarter of 2024, driven by less favorable benefits experience in the life and accident, sickness and disability product lines.

Closed Block Segment
The Closed Block segment reported adjusted operating income of $21.1 million in the fourth quarter of 2025, which excludes the amortization of the cost of reinsurance of $48.8 million and the impact of non-contemporaneous reinsurance of $9.5 million, compared to $27.7 million in the fourth quarter of 2024, which excludes the amortization of the cost of reinsurance of $10.3 million and the impact of non-contemporaneous reinsurance of $4.9 million. Premium income for this segment is largely driven by our long-term care product line, and in the fourth quarter of 2025, premium income decreased 10.1 percent to $196.4 million, compared to $218.4 million in 2024, primarily due to the impact of the Fortitude Re reinsurance transaction. Net investment income decreased 20.1 percent to $237.6 million in the fourth quarter of 2025, compared to $297.3 million in the fourth quarter of 2024, primarily driven by a decrease in the level of invested assets resulting from the Fortitude Re reinsurance transaction and lower miscellaneous investment income primarily due to smaller increases in the net asset values on our private equity partnerships.
Policy benefits including remeasurement loss (gain), excluding the impacts of non-contemporaneous reinsurance, for the Closed Block segment were lower in the fourth quarter of 2025, relative to the same period in 2024, driven primarily by the impacts of the Fortitude Re reinsurance transaction and favorable incidence in the all other product line, partially offset by lower claimant mortality in the long-term care product line. The net premium ratio for long-term care at December 31, 2025 of 97.5 percent was generally consistent with the net premium ratio of 97.6 percent as of September 30, 2025.
Corporate Segment
The Corporate segment reported an adjusted operating loss of $51.1 million in the fourth quarter of 2025, which excludes a settlement loss on the U.S. pension plan annuity purchase of $103.8 million and an accelerated charitable contribution of $20.0 million, compared to an adjusted operating loss of $50.4 million in the fourth quarter of 2024, due primarily to higher operating expenses, mostly offset by an increase in net investment income resulting from an increase in the level of invested assets.

Effective Tax Rate
The effective tax rate on adjusted operating income was 20.8 percent in the fourth quarter of 2025, and 21.0 percent for full year 2025.
Outlook
Beginning in 2026, we plan to adjust our calculation of after-tax adjusted operating income to exclude the results of the Closed Block segment. As part of this update, we 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.
The full-year 2026 outlook for after-tax adjusted operating income per share of $8.60 to $8.90 represents growth of approximately 8 percent to 12 percent when comparing to our redefined full-year 2025 result of $7.93 per share.
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:
•After-tax adjusted operating income or loss, which excludes investment gains or losses, certain impacts from reinsurance transactions, reserve assumption updates, and certain other items;
•Book value per common share, which is calculated excluding AOCI;
•Premium income in constant currency, which excludes the impact of fluctuations in exchange rates between the U.S. dollar and the local currencies in which our Unum International segment is conducted. Given volatility in foreign currency exchange markets, exchange rates can fluctuate between periods. We believe translating prior period results using current period local currency exchange rates provides a more comparable view of our results; and
•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.
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 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. 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.
At times, we utilize reinsurance transactions to manage risk related to certain portions of our business including the exit of portions of our Closed Block businesses. As a result, we exclude the amortization of the cost of reinsurance and the amortization of the deferred gain on reinsurance that are recognized after the closing of these transactions. We also exclude the impact of non-contemporaneous reinsurance for these transactions. While the total equity impact of non-contemporaneous reinsurance is neutral, the difference in original discount rates utilized for direct and ceded reserves results in a disproportionate earnings impact. We believe that the exclusion of these items provides a better view of our results from our ongoing businesses.
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 results.

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 have completed reinsurance transactions to exit significant portions of our Closed Block businesses and, effective February 2026, 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, beginning in 2026, we plan to adjust our calculation of after-tax adjusted operating income to exclude the results of the Closed Block segment. As part of this update, we 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. The chart below presents the non-GAAP reconciliation for this redefined after-tax adjusted operating income for 2025.
