7 COMMITTED TO OUR CLOSED BLOCK STRATEGY Consistent execution against strategy to reduce the footprint and the capital demands of the Closed Block NOTABLE PROGRESS: • Full risk transfer reducing LTC footprint by 20% and providing capital benefit • Eliminated tail-risk through the discontinuation of new employee coverage on existing group cases, effective 2/1/2026 • Internal funds withheld reinsurance providing additional policyholder protection, eliminating source of capital volatility, and supporting a dividend to the holding company • Significant progress on our interest rate de-risking efforts. To date we have reduced our capital sensitivity to interest rate movements and recently fully removed morbidity and mortality improvement reserve assumptions, increasing predictability • Strong track record from rate increase program; we have now surpassed rate increase approvals worth over $5.0B of value since we began filing for rate increases in the early 2000’s Improve Value Creation Reduce the Footprint Increase Predictability of Outcomes

8 MONITORING THE HEALTH OF THE CLOSED BLOCK Key Metric Why it’s Important Current Position Fairwind Protections Measured as Fairwind excess capital (pre-tax) plus statutory reserves relative to our best estimate of the value of the liability. This represents a level of protection that could be used to absorb changes to the liability without the need for capital contributions. ~$2.2 billion Progress on Premium Rate Approvals Measures how much we’ve achieved of the rate increase program embedded in our 2025 best estimate ~15% Net Premium Ratio The NPR is the expected lifetime benefit ratio. Movement in the NPR captures claim expense trends over the long-term. In addition, monitoring the remeasurement line captures period-to- period claim emergence and assumption unlocking that isn’t otherwise reflected in NPR movement. 97.5% Treasury Yield for New Money Our best estimate expectation for the 30-Year US Treasury rate over the long-term. Informs our internal analysis of statutory reserve adequacy 4.50%

NON-GAAP FINANCIAL MEASURES 22 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 and amortization of the deferred gain on reinsurance; • 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, as applicable; • Book value per common share, which is calculated excluding accumulated other comprehensive income (loss) (AOCI); and • 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 provide a more comparable view of our results. Investment gains or losses primarily include realized investment gains or losses, expected investment credit losses, impairment losses, and gains or losses on derivatives. Investment gains or losses depend on market conditions and do not necessarily relate to decisions regarding the underlying business of our segments. Our investment focus is on investment income to support our insurance liabilities as opposed to the generation of investment gains or losses. Although we may experience investment gains or losses which will affect future earnings levels, a long-term focus is necessary to maintain profitability over the life of the business since our underlying business is long-term in nature, and we need to earn the interest rates assumed in calculating our liabilities. 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. 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.
