#### Transformation of the business model.
We are deepening value creation and positioning the customer at the centre of our management:

• We provide our key segments an increasingly tailored offering, enabling us to build stronger relationships. Customer base growth (+6% year-on-year), combined with transactionality and positive performances in value-added products, reflect our progress as a trusted financial partner.

• The network effect resulting from our global structure is a key asset which enables us to better serve our customers. Business growth with multinational corporates (8% increase year-on-year in revenue) is a clear example of how this scale allows us to offer integrated and differentiated solutions.

•

#### Structural efficiency improvement.
The transformation of our operating and business model continued to drive structural efficiency improvements through greater commercial power, focusing on expanding value-added services, together with operational leverage and common technology.
