Covered Bond Investor Report KB EUR HZL 0001 - September 30, 2025

Komerční_banka_EUR_HZL_0001

International Cover Pool means a part of the assets of the Issuer, which is recorded separately and which is composed of assets satisfying the relevant contractual and statutory eligibility criteria set out in the Trust Deed to cover the obligations of the Issuer arising from the Mortgage Covered Bonds (including, among other things, their aggregate nominal value and proportionate yield) with a cover pool identifier: Komerční_banka_HZL_EUR_0001.

The Issuer operates two Cover Pools. The first is the International Cover Pool, which covers the Mortgage Covered Bonds issued under the €5,000,000,000 Mortgage Covered Bond Programme dated 4 January 2021 (and certain other Accessory Debts).

The second is the Local Cover Pool, which covers the covered bonds issued under the Local Covered Bond Programme (and certain other debts).

All figures are current as of 30 September 2025.

The amount of Mortgage Loans is calculated as total of balance of loans adjusted for the 80% LTV cap.

Debts denominated in EUR are expressed in CZK based on the Exchange Rate as of reporting date (30 September 2025).

OC limit statutory (Statutory Minimum OC Level Test) 2.00% OC limit contractual (Contractual Minimum OC Level Test) 5.00% Over-collateralisation target 20.00%

Over-collateralisation actual 20.01%

Mortgage Loans coverage limit (Statutory 85% Test) 85.00% Mortgage Loans coverage actual 118.46%

For the purpose of the calculations in respect to the Statutory Minimum OC Level Test and the Statutory 85% Test the Nominal Value of the Mortgage Loan which exceeds 80% of the Mortgaged Property Value is disregarded to such extent (i.e. issuer applies stricter treatment than the law requirement to disregard only the Nominal Value of the Mortgage Loan which exceeds 100% of the Mortgaged Property Value). Such stricter treatment leads to consistency among calculations of statutory and contractual tests while respecting contractual eligibility criterion that the Mortgage Loan receivables amount included in the International Cover Pool is capped at a maximum LTV Ratio of 80%.

Maturity extension trigger: If the Issuer fails to redeem all Mortgage Covered Bonds of a Series (the Relevant Series) in full on the Maturity Date or within 14 Business Days thereafter, the maturity of the principal amount outstanding of the Mortgage Covered Bonds of the Relevant Series will be automatically extended up to the Extended Maturity Date.

Averages of remaining term, interest rate reset and LTV are weighted by the Adjusted Value of Mortgage Loans (LTV 80% cap) adjusted for the 80% LTV test.

For loans where future interest rate has been formally agreed (with bank customer forfeiting the option of early repayment) the interest reset date reflects the term of this forward rate agreement.

All loans meet the Statutory and Contractual Eligibility Criteria:

• There is a first ranking mortgage in favor of the Issuer securing repayment of the relevant Mortgage Loan, which is also not subject to any other security interest of the same or prior ranking or any prior restrictions on disposals unless they cease to exist as a result of repayment of the obligations secured by them from the proceeds of the relevant mortgage loan

• The mortgage loan receivables amount included in the cover pool is capped at a maximum LTV ratio of 80%

• The mortgage loans are all denominated and payable by the relevant borrower in Czech Koruna

  The projection is based on the following assumptions:

• projection of Mortgage Loans cashflow is done on the basis of contractual cashflows (annuity payments)

• projection of EUR cashflows is reported in CZK using current (30 September 2025) exchange rate

• projection of Liquidity Buffer cashflow considers only interest flows, as maturity of the instrument does not imply cash position change at the covered block level (principal received would remain in the covered block as cash)

• projection of Bonds Issued is done on the basis of Extended Maturity (i.e. not contractual maturity)
