Barcelona, November 11, 2024. Grifols, S.A. ("Grifols" or the "Company") announces that it has received the required consents in connection with its previously announced consent solicitation (the "Solicitation") from holders of the Company's €1,300,000,000 7.500% Senior Secured Notes due 2030 (ISIN XS2805351843 (Reg. S) and XS2805352064 (144A)) (the "Notes") to amend certain provisions of the indenture dated April 30, 2024, as amended or supplemented (the "Indenture") governing the Notes in order to, among other things, align certain provisions of the Notes and the Indenture with the terms and conditions of the Company's more recently-issued 7.125% senior secured notes due 2030 and the indenture governing such notes (the "Proposed Amendments").

As of 11:20 a.m. London time of the date hereof (the "Revocation Deadline"), the Company had received the Required Consents from the holders of the Notes to approve the Proposed Amendments described in the consent solicitation statement, dated as of November 4, 2025 (the "Consent Solicitation Statement"). Capitalized terms used herein and not defined shall have the meaning ascribed to them in the Consent Solicitation Statement.

As a result of the receipt of the Required Consents, such consents are now irrevocable and may not be withdrawn or revoked by the Holders. Holders of Notes who validly delivered their consents are eligible to receive the Consent Payment with respect to their consented Notes. The Solicitation will remain open until 4:00 p.m. London time of November 12, 2025 (the "Expiration Time"), to allow additional holders of the Notes to deliver consents should they wish to do so.

Given the receipt of the Required Consents, Grifols will enter into a supplemental indenture in respect of the Indenture and the Notes incorporating the Proposed Amendments. The Proposed Amendments will become effective on the date of execution of the Supplemental Indenture (the "Effective Date"), but the Supplemental Indenture will provide that the Proposed Amendments will not become operative until the conditions precedent set forth in the Consent Solicitation Statement have been satisfied or waived, including the payment of the Consent Payment, in accordance with the terms of the Solicitation.

If the Proposed Amendments become operative, the Holders who did not consent to the Proposed Amendments on or prior to the Expiration Time, including any transferees of the Notes from such Holders, will still be bound by the Proposed Amendments and will not receive a Consent Payment.

Additional details regarding the Solicitation are described in the Consent Solicitation Statement. This announcement must be read in conjunction with the Consent Solicitation Statement.

Neither this announcement nor the Solicitation is an offer to sell the securities of the Company. No offering of securities was or will be made in connection with the Solicitation. The Consent Solicitation Statement does not constitute or contemplate an invitation to participate in the Solicitation in any jurisdiction in which, or to any person to whom, it is unlawful to make such invitation or for there to be such participation under applicable securities laws. The distribution of the Consent Solicitation Statement in certain jurisdictions may be restricted by law. Persons into whose possession the Consent Solicitation Statement comes are required to inform themselves about, and to observe, any such restrictions. Nothing in the Consent Solicitation Statement constitutes or contemplates an invitation to participate in the Solicitation by a holder of the Notes in any circumstances in which such participation is unlawful.
