Morningstar DBRS Upgrades Credit Ratings on Unione di Banche Italiane S.p.A. Covered Bonds (OBG - Mortgages - Programme 1) to AA (high) from AA (low)

DBRS Ratings GmbH (Morningstar DBRS) upgraded its credit ratings on the Obbligazioni Bancarie Garantite (OBG; the Italian legislative covered bonds) issued under the Unione di Banche Italiane S.p.A. Covered Bonds (OBG - Mortgages - Programme 1) (the Programme) to AA (high) from AA (low).

Concurrently, Morningstar DBRS discontinued its credit ratings on Series 17 (ISIN IT0005067076), which matured in February 2025.

As of the date of this credit rating action, there were 7 series of OBG under the Programme, totalling an outstanding nominal amount of EUR 3.7 billion. The series are guaranteed by UBI Finance S.r.l. (the Guarantor).

This rating action follows the completion of a full review of the ratings.

CREDIT RATING RATIONALE
This credit rating action reflects the ongoing interest rate decrease that has occurred since the previous annual review, which positively affects the Pass-OC level which corresponds to stresses associated with a given credit rating level. Furthermore, Morningstar DBRS update to the "Interest Rate and Currency Stresses for Global Structured Finance Transactions Methodology" on 3 September 2025 also has a positive impact in the analysis. This methodology outlines the framework for generating interest rate and foreign exchange stresses that Morningstar DBRS uses in its analysis of structured finance transactions and covered bonds.

The credit ratings are based on the following analytical considerations:
-- A Covered Bonds Attachment Point (CBAP) of `A', which is Intesa Sanpaolo (ISP)'s Long Term Critical Obligations Rating. ISP is the Issuer and Reference Entity (RE) for the Programme.
-- A Legal and Structuring Framework (LSF) Assessment of "Adequate" associated with the Programme.
-- A Cover Pool Credit Assessment (CPCA) of BBB, which is the lowest CPCA in line with the LSF-Implied Likelihood (LSF-L).
-- An LSF-L of AA (low).
-- A two-notch uplift on the LSF-L for high recovery prospects.
-- A level of overcollateralisation (OC) of 17.8% to which Morningstar DBRS gives credit, which is the minimum level observed in the last 12 months adjusted by a scaling factor of 0.85. ISP commits to a level of OC of 13.0%.
-- The sovereign rating of the Republic of Italy, rated BBB (high) with a Positive trend by Morningstar DBRS, as of the date of this press release.

Morningstar DBRS analysed the transaction with its European Covered Bond Cash Flow Tool. The main assumptions focused on the timing of defaults and recoveries of the assets, interest rate stresses, and market value spreads to calculate liquidation values on the CP. Morningstar DBRS assumed the observed prepayment rate.

Everything else being equal, a one-notch downgrade of the CBAP would lead to a one-notch downgrade of the LSF-L, resulting in a one-notch downgrade of the covered bonds rating. In addition, all else unchanged, the CB ratings would be downgraded if any of the following occurred: (1) the CPCA was downgraded below BBB; (2) the quality of the CP and the level of OC were no longer sufficient to support a two-notch uplift for high recovery prospects; (3) the relative amortisation profile of the CB and CP moved adversely; (4) the LSF assessment associated with the Programme was downgraded; (5) volatility in the financial markets caused the currently estimated market value spreads to increase, or (6) the sovereign rating on the Republic of Italy was downgraded below BBB (low).

Intesa Sanpaolo acts as the account bank, which also holds the reserve account. Based on the credit ratings on ISP and on the account bank's replacement provisions included in the documentation, Morningstar DBRS considers the risk of this counterparty to be consistent with the ratings assigned, in accordance with its "Legal and Derivative Criteria for European Structured Finance Transactions" methodology.

The total outstanding amount of OBG is EUR 3.7 billion as of the date of this press release. The total outstanding amount of OBG was EUR 3.7 billion as of 30 June 2025 (the cut-off date), while the aggregate balance of the CP was EUR 3.8 billion of residential mortgages plus EUR 0.6 billion of cash collections, resulting in a total OC of 19.9%.

As of the cut-off date, the CP comprised 65.,015 first-ranking residential mortgages, mainly originated by network banks of the Unione di Banche Italiane S.p.A. group.

The weighted-average (WA) indexed current loan-to-value ratio of the mortgages was 41.2% with a seasoning of 14.3 years. The CP was mainly distributed in the Italian regions of Lombardy (33.5% by outstanding balance) and Lazio (17.0%).

The CP comprised fixed-rate loans (36.5%) and floating-rate loans (63.5%), the former of which includes mixed loans as well as optional loans currently featuring a fixed-rate coupon. The floating-rate mortgage loans are indexed to different plain-vanilla bases and reset at different dates.

In comparison, as of the cut-off date, 94.6% of the liabilities pay a fixed rate and 5.4% pay a floating rate linked to three-month Euribor. The resulting interest and basis risks are unhedged. Morningstar DBRS considered this in its cash flow analysis.

All CP assets and OBG are denominated in euros. As such, investors are not currently exposed to any foreign exchange risk.

As of the cut-off date, The WA life (WAL) of the CP was 7.4 years whereas the WAL of the OBG was 2.4 years. The resulting asset-liability maturity mismatch is mitigated by the 12-month maturity extension in case of an Issuer event of default and by the OC.

Morningstar DBRS assessed the LSF related to the UBI OBG1 as "Adequate", according to its rating methodology.
