LTC Progress Focused on Active Management Proactive approach to managing block across all dimensions of the business 14 Material progress made recently • 31 rate increase approvals in 2025 with an average rate increase amount of 28% • Approximately 1,200 buyouts in 2025 with $51M of cash paid • Increased the fixed-income duration for the LTC portfolio to ~10 years, up ~1 year from 2021, taking advantage of the higher interest rate environment; asset and liability durations generally matched • Strategic investments in claims management, anti-fraud and wellness initiatives to improve financial outcomes Ability to Withstand Stresses • Prudent reserving assumptions informed by historical experience, including no morbidity improvement, 10 years of mortality improvement, negligible future premium risk and an ultimate 10-year treasury rate assumption of 3.00% • $1.5b of Statutory reserve margin as of September 30, 2025, following 2025 assumption updates Significantly improved runoff Long Term Care business compared to 2015 • Individual LTC block closed in 2004; Group LTC block closed to new accounts in 2004 and closed to new enrollees in 2016 • Total policy counts have reduced ~50% since 2015 • The larger Individual LTC reserves have peaked and are decreasing, while Group LTC reserves will peak at levels less than half of Individual LTC due to less rich benefits • Premium rates are 93% higher than original pricing & 84k policyholders have reduced coverage since 2017

Individual LTC Block Characteristics More mature, richer benefit ILTC reserves have reached inflection point 15 Commentary Block Characteristics • De-risking of the more mature ILTC block with richer policy benefits is well underway ◦ We believe the ILTC reserve balance is at peak levels and declining with significant policyholder experience utilized for assumption setting • Total ILTC policies have declined by 50% (~96,000 policies) since 2015 with stable open claim counts ◦ We expect approximately 65% of existing ILTC policies will run off over the next 10 years Individual Block Be ne fit s Average Age 83 years old Average Max Daily Benefit $333 % of policies with Lifetime Benefits 39% Average Benefit Period (non-lifetime) 3.8 years % of policies with Compound Inflation 44% % of policies with Simple Inflation 22% C la im s # of Open Claims 12.4k Average Age of New Claimant 86 years old 1 Reserves are discounted at locked-in discount rates. 2 ILTC metrics do not include CNA's 50% coinsurance business (26k healthy policies and 3k claims as of Q3 2025). 3 Healthy policies do not include 8k non-forfeiture limited benefit policies as of Q3 2025.

Results for the Three Months Ended September 30 Results for the Nine Months Ended September 30 (In millions) 2025 2024 2025 2024 Net income $403 $283 $976 $938 Less: Net investment losses (6) (7) (49) (33) Less: Pension settlement transaction losses — (3) — (3) Core income $409 $293 $1,025 $974 Core income (loss) is calculated by excluding from net income (loss) the after-tax effects of net investment gains or losses and gains or losses resulting from pension settlement transactions. Net investment gains or losses are excluded from the calculation of core income (loss) because they are generally driven by economic factors that are not necessarily reflective of our primary operations. The calculation of core income (loss) excludes gains or losses resulting from pension settlement transactions as they result from decisions regarding our defined benefit pension plans which are unrelated to our primary operations. Management monitors core income (loss) for each business segment to assess segment performance. Presentation of consolidated core income (loss) is deemed to be a non-GAAP financial measure and management believes some investors may find this measure useful to evaluate our primary operations. Reconciliation of Net Income (Loss) per Diluted Share to Core Income (Loss) per Diluted Share Results for the Three Months Ended September 30 Results for the Nine Months Ended September 30 2025 2024 2025 2024 Net income per diluted share $1.48 $1.04 $3.58 $3.44 Less: Net investment losses (0.02) (0.03) (0.18) (0.12) Less: Pension settlement transaction losses — (0.01) — (0.01) Core income per diluted share $1.50 $1.08 $3.76 $3.57 Core income (loss) per diluted share provides management and investors with a valuable measure of the Company's operating performance for the same reasons applicable to its underlying measure, core income (loss). Core income (loss) per diluted share is core income (loss) on a per diluted share basis. 21 Reconciliation of Net Income (Loss) to Core Income (Loss) Reconciliation of GAAP Measures to Non-GAAP Measures

Net income (loss) is the most directly comparable GAAP measure. Management believes some investors may find this measure useful to evaluate the profitability, before tax, derived from our underwriting activities which are managed separately from our investing activities. Underlying underwriting gain (loss) is also deemed to be a non-GAAP financial measure, and represents pretax underwriting results excluding catastrophe losses and development-related items. Management believes some investors may find this measure useful to evaluate the profitability, before tax, derived from our underwriting activities, excluding the impact of catastrophe losses, which are unpredictable as to timing and amount, and development-related items as they are not indicative of our current year underwriting performance.

The underlying combined ratio is the sum of the underlying loss ratio, the expense ratio and the dividend ratio. The underlying loss ratio and the underlying combined ratio are deemed to be non-GAAP financial measures, and management believes some investors may find these ratios useful to evaluate our underwriting performance since they remove the impact of catastrophe losses, which are unpredictable as to timing and amount, and development-related items as they are not indicative of our current year underwriting performance. The components to reconcile the combined ratio and loss ratio to the underlying combined ratio and underlying loss ratio for Property & Casualty, Specialty, Commercial and International segments are set forth on pages 5, 7, 9 and 11, respectively.
