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, Closed Block segment adjusted operating income or loss, as well as certain other items, as applicable;

•Adjusted operating return on equity, which is calculated using our core operating segments after-tax segment adjusted operating income or loss and our core operating segments' equity adjusted to exclude 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;

•After-tax segment adjusted operating income or loss, which excludes investment gains or losses, as well as certain other items, as applicable;

•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;

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

We measure and analyze our segment performance on the basis of "segment adjusted operating revenue" and "segment adjusted operating income" or "segment adjusted operating loss", which differ from total revenue and income before income tax as presented in our consolidated statements of operations due to the following items:

•Segment adjusted operating revenue, which excludes investment gains or losses, as well as certain other items, as applicable;

•Segment adjusted operating income or loss, which excludes investment gains or losses, as well as certain other items, as applicable.

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 segments. 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 have completed reinsurance transactions to exit significant portions of our Closed Block businesses and 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, we exclude the results of the Closed Block segment from after-tax adjusted operating income. As part of this update, we also 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. Prior period financial information has been adjusted to conform to this updated presentation.

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 no longer exclude reserve assumption updates from our adjusted operating results, and prior period financial information has been adjusted to conform to this updated presentation.

For a reconciliation of the most directly comparable GAAP measures to these non-GAAP financial measures, refer to the "Reconciliation of Non-GAAP Financial Measures" beginning on page 15.3, other than book value per common share, which is presented on page 2.

1 Excludes unrealized loss on securities, the effect of change in discount rate assumptions on the liability for future policy benefits, and net loss on derivatives and is calculated using the stockholders' equity balances presented on page 15.7. Due to updates to our calculation of after-tax adjusted operating income for which the beginning balance of 2026 for certain stockholders' equity line items were adjusted, we are computing the average allocated equity for 2026 using internally allocated equity that reflects the adjusted beginning balance at January 1, 2026. As a result, average equity for the nine months ended September 30, 2026 for certain of our segments will not compute using the historical allocated equity at December 31, 2025.

The tax effects are calculated discretely using applicable statutory tax rates for the jurisdictions in which the underlying adjustments occur. The effective tax rate on reconciling items may differ from the Company’s consolidated effective tax rate.
