LINCOLN NATIONAL CORP

Details underlying the results for Life Insurance (in millions) were as follows:

(1)Includes term insurance premiums, which have a corresponding partial offset in benefits and policyholder liability remeasurement for changes in reserves. The decrease in insurance premiums in the third quarter of 2025 was driven by the expiration of a 10-year assumed reinsurance treaty in the first quarter of 2025, which has a corresponding offset in benefits and policyholder liability remeasurement.

Comparison of the Three and Nine Months Ended September 30, 2025 to 2024

Income from operations for this segment increased due primarily to the following:

•Higher net investment income, net of interest credited, driven by growth in investments and moderate spread expansion.

•Higher fee income driven by higher deferred front-end loads (“DFEL”) amortization.

•Lower commissions and other expenses, net of amortization of deferred loss on business sold through reinsurance, due to expense management.

The increase in income from operations for this segment was partially offset by higher benefits and policyholder liability remeasurement driven by the impact from our annual assumption review and aging of the block, partially offset by improved mortality due to lower claims incidence.

Additionally, for the nine months ended September 30, 2025, the increase in income from operations was driven by higher net investment income, net of interest credited, due to higher investment income on alternative investments.

Risk Factors – Market Conditions – Changes in interest rates and sustained low interest rates may cause interest rate spreads to decrease, impacting our profitability, and make it more challenging to meet certain statutory requirements,” “Part I – Item 1A. Risk Factors – Market Conditions – Increases in interest rates and sustained high interest rates may negatively affect our profitability, capital position and the value of our investment portfolio and may also result in increased contract withdrawals and surrenders” and “Part II – Item 7A.

Insurance Premiums

Insurance premiums relate to traditional products and are a function of the rates priced into the product and insurance in force. Insurance in force, in turn, is driven by sales, persistency and mortality claims.

Details underlying fee income, sales, net flows, account balances and in-force face amount (in millions) were as follows:

(1) Net of reinsurance ceded.

Fee income relates only to interest-sensitive products and includes cost of insurance assessments, expense assessments and surrender charges. Both cost of insurance and expense assessments can have deferrals and amortization related to DFEL. Cost of insurance and expense assessments are deducted from our policyholders’ account balances. These amounts are a function of the rates priced into the product and premiums received, face amount in force and account balances.

Sales are not recorded as a component of revenues (other than for traditional products) and do not have a significant effect on current quarter income from operations but are indicators of future profitability. Generally, we have higher sales during the second half of the year with the fourth quarter being our strongest.

Sales in the table above and as discussed above were reported as follows:

•UL, IUL and VUL – first-year commissionable premiums plus 5% of excess premiums received;

•MoneyGuard® linked-benefit products –MoneyGuard (UL) and MoneyGuard Market Advantage SM(VUL), 150% of commissionable premiums;

•Executive Benefits – insurance and corporate-owned UL and VUL, first-year commissionable premiums plus 5% of excess premium received, and single premium bank-owned UL and VUL, 15% of single premium deposits; and

•Term – 100% of annualized first-year premiums.

We monitor the business environment, including but not limited to the regulatory and interest rate environments, and make changes to our product offerings and in-force products as needed, and as permitted under the terms of the policies, to sustain the future profitability of our segment.

(1) See “Consolidated Investments – Commercial Mortgage Loan Prepayment and Bond Make-Whole Premiums” below for additional information.

(2) Represents net investment income on the required statutory surplus for this segment and includes the effect of investment income on alternative investments for such assets that are held in the portfolios supporting statutory surplus versus the portfolios supporting product liabilities.

(3) Includes primarily net investment income earned on our alternative investments portfolio. See “Consolidated Investments – Alternative Investments” below for more information on alternative investments.

A portion of the investment income earned for this segment is credited to policyholder accounts. Statutory reserves will typically grow at a faster rate than account balances because of reserve requirements. Investments allocated to this segment are based upon the statutory reserve liabilities and are affected by various reserve adjustments, including financing transactions providing relief from reserve requirements. These financing transactions lead to a transfer of investments from this segment to Other Operations. We expect to earn a spread between what we earn on the underlying general account investments and what we credit to our policyholders’ accounts. Investment income partially offsets the earnings effect of the associated growth of our policy reserves. Commercial mortgage loan prepayments and bond make-whole premiums and investment income on alternative investments can vary significantly from period to period due to a number of factors, and, therefore, may contribute to investment income results that are not indicative of the underlying trends.

Details underlying benefits and policyholder liability remeasurement (dollars in millions) were as follows:

(1) Includes primarily long-term care claims and life surrender benefits.

Benefits for this segment include claims incurred during the period in excess of the associated reserves for its interest-sensitive and traditional products. In addition, benefits include the change in secondary guarantee, linked-benefit and term life insurance product reserves. These reserves are affected by changes in expected future trends of assessments and benefits causing remeasurements. Generally, we experience higher mortality in the first quarter of the year due to the seasonality of claims.

Commissions and other expenses that result directly from and are essential to the successful acquisition of new or renewal business are deferred to the extent recoverable. For our interest-sensitive and traditional products, DAC and value of business acquired (“VOBA”) are amortized on a constant level basis over the expected term of the related contracts using the groupings and actuarial assumptions consistent with those used for calculating the related policyholder liability balances.
