Pursuant to the provisions of Article 227 of Law 6/2023 of March 17, on Securities Markets and Investment Services, Grifols, S.A. (“ Grifols ” or the “ Company ”) hereby informs about the following

OTHER RELEVANT INFORMATION

Grifols announces that it has concluded today a successful refinancing of its 2027 debt maturities by means of a credit agreement, in the form of a Term Loan B (“ TLB ”), structured in three tranches: (i) a term loan in US dollars with a principal amount of USD 2,000,000,000; (ii) a term loan in euros with a principal amount of EUR 1,250,000,000; and (iii) a revolving credit facility with a maximum available amount of USD 2,065,000,000.

The term loans will have a maturity of seven years from the date of execution of the agreement, whilst the revolving credit facility will have a maturity of six and a half years, subject to the conditions therein. The U.S. dollar TLB was set at SOFR ( Secured Overnight Financing Rate ) + 250 basis points with an OID ( Original Issue Discount ) of 99.25. The euro tranche was set at Euribor + 300 basis points with an OID of 99.75. Both the TLB and the Revolving Credit Facility benefit from leverage-based margin step-downs.

The proceeds obtained under the aforementioned financing will be used to (i) fully repay the outstanding loans under the existing 2019 TLB credit facilities, (ii) redeem and discharge the remaining outstanding amount under the existing 2019 Notes; (iii) to provide the Group with available liquidity for its development, supporting the simplification and extension of Grifols’ debt maturity profile.

The refinancing together with the redemption of EUR 500,000,000 in aggregate principal amount of the existing April 2024 Notes made public yesterday, will strengthen the company’s balance sheet by reducing funded gross debt levels, lowering cash interest expense, improving its debt maturity profile, whilst maintaining strong liquidity levels.

In Barcelona, on 14 April 2026
