LTC Progress Focused on Active Management Proactive approach to managing block across all dimensions of the business 14 Material progress made recently • 35 rate increase approvals in 2024 with an average rate increase amount of 75% • Approximately 2,100 policy buyouts, totaling $67M in cash payments in 2024 • 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 foundational capabilities to maintain CNA as a leader in the wellness space Ability to Withstand Stresses • Prudent reserving assumptions informed by historical experience (no morbidity improvement, 10 years of mortality improvement, minimal future rate actions, ultimate 10 year treasury rate of 3.00%) • $1.4b of Statutory reserve margin as of September 30, 2024, following 2024 annual assumption review 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 • 46% reduction in both individual and group policy counts since 2015 • Premium rates are ~50% higher than in 2015 & ~80k policyholders have reduced coverage since 2017 • Normative 10 year risk free rate assumption of 3.00% compared to 2015’s assumption of 4.80%

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 46% (~87,000 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 B en ef its Average Age 82 years old Average Max Daily Benefit $287 % of policies with Lifetime Benefits 39% Average Benefit Period (non-lifetime) 3.9 years % of policies with Compound Inflation 44% % of policies with Simple Inflation 23% C la im s # of Open Claims 12.9k 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 (27k healthy policies and 3k claims as of Q3 2024). 3 Healthy policies do not include 8k non-forfeiture limited benefit policies as of Q3 2024.

Results for the Three Months Ended September 30 Results for the Nine Months Ended September 30 ($ millions) 2024 2023 2024 2023 Net income $283 $258 $938 $838 Less: Net investment losses (7) (31) (33) (84) Less: Pension settlement transaction losses (3) — (3) — Core income $293 $289 $974 $922 Core income (loss) is calculated by excluding from net income (loss) the after-tax effects of net investment gains or losses and gains or losses resulting from pension settlement transactions. Net investment gains or losses are excluded from the calculation of core income (loss) because they are generally driven by economic factors that are not necessarily reflective of the Company's primary operations. The calculation of core income (loss) excludes gains or losses resulting from pension settlement transactions as they result from decisions regarding the Company's defined benefit pension plans which are unrelated to the Company's primary operations. Management monitors core income (loss) for each business segment to assess segment performance. Presentation of consolidated core income (loss) is deemed to be a non-GAAP financial measure. Reconciliation of Net Income (Loss) per Diluted Share to Core Income (Loss) per Diluted Share Results for the Three Months Ended September 30 Results for the Nine Months Ended September 30 ($ millions) 2024 2023 2024 2023 Net income per diluted share $1.04 $0.95 $3.44 $3.08 Less: Net investment losses (0.03) (0.11) (0.12) (0.31) Less: Pension settlement transaction losses (0.01) — (0.01) — Core income per diluted share $1.08 $1.06 $3.57 $3.39 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 GAAP Measures to Non-GAAP Measures Reconciliation of Net Income (Loss) to Core Income (Loss)

22 Reconciliation of GAAP Measures to Non-GAAP Measures Underwriting gain (loss) is deemed to be a non-GAAP measure and is calculated pretax as net earned premiums less total insurance expenses, which includes insurance claims and policyholders' benefits, amortization of deferred acquisition costs and other insurance related expenses. Net income (loss) is the most directly comparable GAAP measure. Management believes some investors may find this measure useful to evaluate profitability, before tax, derived from our underwriting activities which are managed separately from our investing activities. Underlying underwriting gain (loss) is deemed to be a non-GAAP measure that represents pretax underwriting results excluding catastrophe losses and development-related items. Management believes some investors may find this measure useful to evaluate profitability, before tax, of 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 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.
