As a result of new rules on depositor preference, Moody's is conducting a review of Crédit Mutuel Arkéa's ratings

Brest, April 22^nd 2026 - In line with the implementation of European rules on bank crisis management and deposit insurance, rating agency Moody's has made several adjustments to the ratings of French banking groups, including Crédit Mutuel Arkéa.

On 26 March 2026, the European Union adopted an expansion of the framework for bank crisis management and deposit insurance (commonly referred to as CMDI — "Crisis Management and Deposit Insurance"). This legislation aims to extend resolution mechanisms to a greater number of banks while limiting the use of public funds and better protecting depositors. This means that in the event of a bank's insolvency, deposits have a higher priority for repayment than "senior" debt. This change is regarded as positive for deposit safety but negative for holders of "senior" debt, who may absorb greater losses in the event of failures.

In line with this legislation, on 21 April 2026 Moody's implemented several rating actions for Crédit Mutuel Arkéa:

• it upgraded the long-term deposit rating, reflecting Moody's view that protection for all depositors has been strengthened;
• and it affirmed the issuer and Senior Preferred ratings while revising their outlooks from Stable to Negative, signaling a higher potential loss for holders of those instruments. These outlooks also mirror Moody's Negative outlook on the French government.

These revisions therefore affirm the strong quality of Crédit Mutuel Arkéa's ratings, which reflect a robust business model that enables the Group to reaffirm its long?term strategy.

The Short?Term ratings remain unchanged.
