Moody's confirmed its A2 long-term and P-1 short-term ratings in Q4 2024 and maintained the positive outlook they had previously improved in Q2 2024, following the same movement in the rating of the Kingdom of Spain, and maintaining it two notches above the sovereign. In Q3 2024, S&P Global confirmed Santander's credit rating at A+ for long-term and A1 for short-term debt. In Q2 2024, S&P rated our AT1 instruments as BBB- (investment grade). They maintained Santander's outlook as stable, in line with the sovereign. Fitch upgraded Santander's long-term senior rating to A+ in Q1 2025. Fitch and DBRS maintained their stable outlooks, above the sovereign. Sometimes the methodology applied by the rating agencies limits a bank's rating to the sovereign rating of the country where it is headquartered. Banco Santander, S.A. is still rated above the sovereign debt rating of the Kingdom of Spain by Moody’s, DBRS and S&P and rated at the same level by Fitch, which demonstrates our financial strength and the benefits from our diversification.
