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.”

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.

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.

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.

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.

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 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.

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.

The Company’s weighted average number of shares outstanding, assuming dilution, was 168.0 million for the fourth quarter of 2025, compared to 181.6 million for the fourth quarter of 2024. Shares outstanding totaled 165.7 million at December 31, 2025. During the fourth quarter of 2025, the Company repurchased 3.3 million shares at a total cost of $252.5 million.

At December 31, 2025, the weighted average risk-based capital ratio for the Company’s traditional U.S. insurance companies was approximately 440 percent, and the holding companies had available holding company liquidity of $2,344.1 million.

Book value per common share as of December 31, 2025 was $67.11, compared to $61.38 at December 31, 2024. Book value per common share excluding AOCI as of December 31, 2025 was $78.02, compared to $75.51 at December 31, 2024.

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.

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.

•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.
