Barcelona, Spain – July 29, 2025 – Grifols (MCE:GRF, MCE:GRF.P, NASDAQ:GRFS), a global healthcare company and leader in plasma-derived medicines, today announced results for the first half of 2025, driven by a second quarter marked by continued improvements across key operational and financial metrics. These results reflect the ongoing execution of Grifols’ Value Creation Plan.

Revenues for the first half of the year grew by 7.0% cc to EUR 3,677 million, driven by the performance of the Biopharma business, which increased by 8.2% cc. Adjusted EBITDA reached EUR 876 million, up by 12.7% cc year-over-year, representing a 23.8% margin, supported by product mix, continuous improvement initiatives and operational leverage. Net profit surged to EUR 177 million, reflecting a 387.6% increase compared to the same period of 2024.

Free cash flow pre-M&A significantly improved to positive EUR 30 million in the second quarter, resulting in minus EUR 14 million for the first half of the year. This represents a EUR 182 million year-over-year improvement, mainly driven by EBITDA growth, working capital management and reduced interest costs.

Grifols further strengthened its financial position, reducing its leverage ratio to 4.2x, down from 4.5x in the previous quarter and 5.5x in the first half of 2024, with a liquidity position of EUR 1.4 billion. The company remains focused on continuing to improve its credit profile.

As part of its capital allocation framework, Grifols successfully completed the delisting of Biotest from the Frankfurt Stock Exchange and increased its equity stake to 80.32%. This transaction, with a total cost of EUR 108 million, was fully funded through available financial resources.

The company declared a EUR 0.15 per share dividend payment supported by continued underlying earnings and free cash flow generation momentum. This reflects the company’s strong commitment to shareholder returns.

Nacho Abia, CEO of Grifols, said: “The company’s strong performance in the first six months of 2025 reflects the solid execution of our Value Creation Plan. The momentum of the business is clear: in a context of strong underlying demand, we continue to capitalize on the strength of our Biopharma business unit while advancing on key priorities.”

Nacho Abia added: “While the value creation will ultimately benefit our shareholders, we continue to be fully committed to developing solutions that address patients’ needs - a priority that has defined Grifols for more than 116 years.”

Rahul Srinivasan, CFO of Grifols, said: “The company's strong first-half performance underscores both the attractive fundamentals and resilience of our business. We remain resolutely focused on leveraging the strengths of our business model and disciplined execution, capitalizing on our underlying momentum and operational focus to deliver on our deleveraging and free cash-flow generation priorities, whilst reinforcing the strong confidence in the company’s long-term value.”

On the exposure and potential impact of trade tariffs, the company is well-prepared, thanks to a locally operated and vertically integrated business model. Since its international expansion over 30 years ago, Grifols has invested consistently in a global network of donation, processing, and distribution centers for plasma-derived medicines, allowing it to operate locally in the United States, Europe, Egypt, and Canada. The integration minimizes the need for imports and/or exports within the U.S. market and also strengthens its flexible and resilient structure in the face of regulatory changes or new tariffs.

Biopharma drives strong growth in the first half of 2025

Biopharma revenue grew by 8.2% cc, led by continued momentum in the immunoglobulin (IG) franchise, while Alpha-1 continued to gain traction. Specifically, IG revenues rose by 12.5% cc, with strong growth in both its intravenous form (IVIG), which outpaced market growth, and subcutaneous form (SCIG), which delivered 66% cc in the first part of 2025. Grifols continues to consolidate its leadership in key indications such as primary and secondary immunodeficiencies and CIDP.

Albumin posted sequential improvement in Q2 2025, following license renewal in China. The 1.3% cc growth in this quarter resulted in a first half performance of minus 3.7% cc.

Revenues from Alpha-1 and Specialty proteins continued to perform positively, growing 4.8% cc in the first half of the year. Alpha-1 continues to benefit from the company’s leading 70% global market share. As part of this protein’s commercial growth strategy, the SPARTA study and the subcutaneous formulation trial for Alpha-1 are progressing as planned.

Grifols maintains its plan to launch fibrinogen in Europe in the fourth quarter of 2025 and in the United States in the first half of 2026, following FDA approval.

Diagnostic business maintains positive momentum

Diagnostic revenues reached EUR 332 million, an increase of 2.8% cc, driven by Molecular Donor Screening (MDS) across EMEA and Asia-Pacific, as well as solid performance in Blood Typing Solutions (BTS) in key countries. Noteworthy is the FDA approval to begin manufacturing Gel Cards and reagent Red Blood Cells at Grifols’ San Diego facility.

Grifols reaffirms 2025 guidance and improves the Free Cash Flow pre-M&A guidance

As Grifols enters the second half of 2025 with strong underlying momentum across its core businesses, the company reaffirms its 2025 guidance shared during its Capital Markets Day on February 27, 2025, and improves the guidance for Free Cash Flow pre-M&A guidance to EUR 375-425 million.

While the recent depreciation of the U.S. dollar presents a headwind to reported Revenue and EBITDA in the second half, the impact on Group Profit, leverage and Free Cash Flow pre-M&A is expected to be broadly neutral. The Group expects to largely mitigate this headwind through a combination of the benefit of underlying business momentum and targeted cost levers.

| a) Accounting principles and basis of consolidation applied The accounting policies and basis of consolidation applied in the preparation of the condensed consolidated interim financial statements for the first semester of 2025, except for those detailed in the table below, are the same as those used in the preparation of the consolidated Annual Accounts for the year ended 31 December 2024. In addition, the following standards issued by the IASB and the IFRS Interpretations Committee, and adopted by the European Union for their application in Europe have become effective for the year 2025 and, accordingly, have been considered for the preparation of these condensed consolidated interim financial statements. The application of these standards and interpretations has had no significant impact on these condensed consolidated interim financial statements: Mandatory application for annual periods beginning on or after: Standards IASB effective date EU effective date IAS 21 Amendments to IAS 21 The Effects of Changes in Foreign Exchange Rates: Lack of Exchangeability (issued on 15 August 2023) 1 January 2025 1 January 2025 New IFRS and Amendments to IFRS Not Yet Effective as of 30 June 2025 As of the date of preparation of these condensed consolidated interim financial statements, the following new standards and amendments have been issued by the IASB but are not mandatory until the future periods indicated below: Mandatory application for annual periods beginning on or after: Standards IASB effective date EU effective date IFRS 9 / IFRS 7 Amendments to the Classification and Measurement of Financial Instruments (Amendments to IFRS 9 and IFRS 7) (issued on 30 May 2024) 1 January 2026 1 January 2026 Annual Improvements Volume 11 (issued on 18 July 2024) 1 January 2026 1 January 2026 IFRS 9 / IFRS 7 Contracts Referencing Nature-dependent Electricity – Amendments to IFRS 9 and IFRS 7 (issued on 18 December 2024) 1 January 2026 1 January 2026 IFRS 18 Presentation and Disclosure in Financial Statements (issued on 9 April 2024) 1 January 2027 Pending IFRS 19 Subsidiaries without Public Accountability: Disclosures (issued on 9 May 2024) 1 January 2027 Pending The Group has not applied any of these standards or interpretations in advance of their effective date. b) Responsibility for relevant disclosures, estimates and judgments when applying policies The information in these condensed consolidated interim financial statements for the six-month period ended at 30 June 2025 is the responsibility of the Company's Directors. The preparation of the condensed consolidated interim financial statements requires management to make judgments, estimates and assumptions that affect the application of the Group's accounting policies. The following notes include a summary of the relevant accounting estimates and judgements used to apply accounting policies that have had the most significant effect on the amounts recognized in these condensed consolidated interim financial statements. • Assumptions used to test non-financial assets for impairment. Relevant cash generating units are tested at least annually for impairment. These are based on risk-adjusted future cash flows discounted using appropriate interest rates. Assumptions relating to risk-adjusted future cash flows and discount rates are based on business forecasts and are therefore inherently subjective. Future events could cause a change in business forecasts, with a consequent adverse effect on the future results of the Group. GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Condensed Consolidated Interim Financial Statements for the six-month period ended 30 June 2025 (Free translation from the original in Spanish.

| • The determination of the fair value of the acquired assets and assumed liabilities in a business combination and the allocation of the purchase price (see notes 3 and 4(a) to the consolidated annual accounts for the year ended December 31, 2024). • Evaluation of the capitalization of development costs (see note 4(d) to the consolidated annual accounts for the year ended December 31, 2024). Key assumption is related to the estimation of sufficient future economic benefits of the projects. • Valuation of inventory and assessment of the recoverability of the carrying value of inventory. The key assumptions consider the regulatory approvals and the forecasted demand for the products marketed by the Group. • The calculation of the income tax expense requires tax legislation interpretations in the jurisdictions where Grifols operates. The decision as to whether the tax authority will accept a given uncertain tax treatment and the expected outcome of outstanding litigation requires significant estimates and judgements. Likewise, Grifols recognizes deferred tax assets, mainly from tax credits and rights to deduct to the extent that it is probable that sufficient taxable income will be available against which temporary differences can be utilized, based on management assumptions regarding amount and payments of future taxable profits (see notes 4(q) and 28 to the consolidated annual accounts for the year ended December 31, 2024). • Determination of chargebacks made to certain customers in the United States (see note 4(p) to the consolidated annual accounts for the year ended December 31, 2024). • The assumptions used for the calculation of the fair value of financial instruments (see notes 29 and 30 to the consolidated annual accounts for the year ended December 31, 2024). • The assessment of the classification as equity instruments of certain financial instruments that, under particular circumstances, may result in a cash outflow (see note 17(a) to the consolidated annual accounts for the year ended December 31, 2024). • Evaluation of whether Grifols controls a subsidiary or not, analyzing factors such as rights derived from contractual agreements, as well as actual and potential voting rights, considering for these purposes the potential voting rights held by Grifols exercisable at the closing date of its fiscal year (see notes 2(b), 10 and 19 to the consolidated annual accounts for the year ended December 31, 2024). • Assessment of the non-existence of a contractual obligation for Grifols. S.A. within the framework of the agreement signed with Haier for the sale of 20% of the shares of Shanghai RAAS in relation to the commitment by which the Company will make its commercially reasonable efforts to ensure that its subsidiary Grifols Diagnostic Solutions, Inc. declares and distributes dividends to its shareholders (see note 29(e) to the consolidated annual accounts for the year ended December 31, 2024). No changes have been made to prior year judgments relating to existing uncertainties. The Group is also exposed to interest rate and currency risks. Grifols' management does not believe that there are any assumptions or estimation uncertainties that pose a significant risk that could give rise to material adjustments in the next year. The relevant estimates and judgements used in the preparation of these condensed consolidated interim financial statements do not differ significantly from those used in the preparation of the consolidated annual accounts as of December 31, 2024, and for the six month ended at 30 June 2025. c) Comparative financial information Grifols' condensed consolidated interim financial statements for the six months ended at 30 June 2025 show comparative figures as of 31 December 2024 for the consolidated balance sheet and the six months ended at 30 June 2024 for the consolidated income statement, consolidated statement of comprehensive income, consolidated statement of changes in equity and consolidated cash flow statement and the related notes.

| d) Seasonality of operations in the period Given the nature of the Group's activities, there are no factors that determine significant seasonality in the Group's operations that would affect the interpretation of these condensed consolidated interim financial statements for the six-month period ended 30 June 2025 in comparison with financial statements for a full year. e) Materiality In determining the disclosures in these explanatory notes in accordance with IAS 34, materiality has been considered in relation to these condensed consolidated interim financial statements. (3) Changes in the consolidation scope The Group prepares its condensed interim consolidated financial statements including its investments in all its subsidiaries, associates and joint ventures. Appendix I to the consolidated annual accounts at 31 December 2024 lists the companies in which Grifols, S.A. has direct or indirect holdings and which have been included in the scope of consolidation at that date. The main changes in the scope of consolidation that have taken place in the six-month period ended 30 June 2025, are detailed below: a) Increase in participation in dependent entities: 30/06/2025 Name Country Parent Description Date Consolidation method % voting rights acquired % total voting rights following acquisition (1) Araclon Biotech Spain Grifols Innovation and New Technologies Limited Acquisition March 25 Full consolidation 0.58% 76.43% Biotest AG Germany Grifols S.A. y Grifols Biotest Holdings, GmbH Acquisition February 25 and June 25 Full consolidation 10.14% 80.32% Biotest MidCo GmbH Germany Grifols S.A.

| Biotest On February 14, 2025, Grifols acquired 589,694 non-voting preferred shares, representing approximately 1.5% of the share capital of Biotest AG at a price of €30.00 per share. The total amount disbursed by the Group amounts Euros 17,690 thousand. As a result of this transaction, the Group, directly and indirectly, became the owner of 71.68% of Biotest AG. On March 31, 2025, Biotest Holdings GmbH announced its decision to make a delisting offer for the acquisition of all ordinary voting shares of Biotest AG ("Biotest") at a price of €43.00 per share, as well as the non-voting preferred shares at a price of €30.00 per share, in accordance with the provisions of the Offer Document. The acceptance period ended on June 6, 2025, the date from which Biotest AG's shares ceased trading on the Frankfurt Stock Exchange. The offer was accepted for a total of: • 416,922 ordinary shares, representing approximately 2.11% of the total issued ordinary shares with voting rights and 1.05% of Biotest's total share capital, and • 3,002,804 non-voting preferred shares, representing approximately 15.18% of the total preferred shares issued and 7.59% of Biotest's total share capital. The total amount disbursed by the Group within the framework of this operation amounted to Euros108,011 thousand. As a result of the delisting offer, the Group, directly and indirectly through its subsidiary Grifols Biotest Holding GmbH, came to hold: • 99.25% of the total ordinary voting shares issued, and • 61.40% of the total non-voting preferred shares issued. The settlement of the offer was carried out on 16 June 2025. In accordance with the provisions of IFRS 10 – Consolidated Financial Statements, this transaction has been accounted for as a transaction with non-controlling interests, as the Group continues to exercise control over Biotest AG. Consequently, there has been no impact on the condensed interim consolidated income statement of the Grifols Group. The impact of the transaction on the consolidated balance sheet as of 30 June 30 2025 is reflected in the following terms: • A decrease under the heading "Non-controlling interests" amounting to Euros 107.7 million, including an effect on translation differences of Euros 6.9 million; and • A change in accumulated reserves (undistributed income) amounting to Euros 24.9 million (see Note 13(b)).

Andorra Grifols Innovation and New Technologies Limited Dissolved March 25 Full consolidation 100.00% —% Immunotek Plasma Centers Acquisition of Plasma Centers - Group 1&2 As a result of the collaboration agreement signed with ImmunoTek GH, LLC, Grifols acquired 7 silos on 1 April 2024 and 7 silos on 1 July 2024, one silo for each plasma center for an amount of US Dollars 134,902 thousand and US Dollars 130,956 thousand, respectively. These transactions meant that Grifols gained control of the 14 centers as of their acquisition date in 2024, which had previously been considered within a joint operation (Group 1 and 2). Therefore, Grifols applied the requirements for a business combination carried out in stages. However, considering that (i) Grifols' effective participation in the joint venture was null and void and (ii) all of the assets and liabilities related to the joint venture were already recognized in the consolidated financial statements, the difference between the consideration paid and the fair value of the assets and liabilities, which would not be deducted from their carrying amount, was recognized as provisional goodwill at the acquisition date for an amount of Euros 233,421 thousand (US Dollars 252,766 thousand). During the current year, and within 12 months from the date of acquisition, the Group has completed the analysis of the adjustments derived from the acquisition, which has led to an adjustment to goodwill in the amount of Euros 2,768 thousand (US Dollars 2,893 thousand). Acquisition of Plasma Centers - Group 3&4 In accordance with the agreements in force between Grifols Bio North America LLC ("GBNA") and Immunotek GH LLC ("Immunotek") (the "Immunotek Collaboration Agreement"), effective January 2, 2025, GBNA acquired a group of 8 plasma collection centers in the U.S. (the "Group 3 Centers") from Immunotek for a total net amount of approximately US Dollars 78,888 thousand. Likewise, and despite the fact that the Collaboration Agreement with Immunotek provided that the acquisition of the Group 4 Centers (defined below) would be carried out in January 2026, in response to the strategic decision to optimize operational efficiency, Immunotek and Grifols signed an amendment to the Collaboration Agreement with Immunotek then in force, pursuant to which, effective 3 February 2025, GBNA acquired from Immunotek the last 6 plasma collection centers in the U.S. (the "Group 4 Centers"), for a purchase price of approximately US Dollars GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Condensed Consolidated Interim Financial Statements for the six-month period ended 30 June 2025 (Free translation from the original in Spanish.

| 62,428 thousand, with payment of the price deferred until 2 January 2026 (as provided for in the original Immunotek Collaboration Agreement). As a result of the above, Grifols has recognized a short-term liability in 2025 for the deferred amount of the acquisition of the Group 4 Centers. The deferred payment obligation has been formalized by a promissory note between Biomat Holdings LLC, as issuer, and Immunotek, as holder of the note, for an aggregate amount of US Dollars 69,861,403 (the "Note") (including mainly management fees related to the centers until May and other concepts amounting to US Dollars 7 million), maturing on 2 January 2026. The Group 4 Centers are encumbered as collateral of the Promissory Note and (following the same guarantee provided by Grifols S.A. under the Collaboration Agreement with Immunotek) the Promissory Note is guaranteed by Grifols, S.A. Therefore, and following the acquisition of the Group 3 Centers and the Group 4 Centers, Grifols has gained control of the 14 centers in 2025 (previously integrated within a joint operation) and now owns and fully manages as of 1 May 2025, through its subsidiary Biomat Holdings LLC, the 28 plasma collection centers in the U.S. developed by Immunotek under the Collaboration Agreement with Immunotek. The collaboration with Immunotek has ended, and GBNA is no longer part of the joint venture, Biotek America LLC. Grifols has applied the requirements for a business combination carried out in stages. However, considering that (i) Grifols' effective participation in the joint venture is null and void and (ii) all of the assets and liabilities related to the joint venture are already recognized in the consolidated financial statements, the difference between the consideration paid and the fair value of the assets and liabilities, which does not differ from their carrying amount, It has been recognized as provisional goodwill at the date of acquisition. The aggregate detail of the cost of the business combination and interim goodwill as of the acquisition date is shown below: Thousands of Euros Thousands of US Dollar Consideration 268,457 281,316 Advance payment (133,601) (140,000) Net consideration 134,856 141,316 Step-up of net assets adquired1 — — Goodwill 268,457 281,316 Adjustments from acquisition 2 (27,109) (28,407) Goodwill, net of adjustments 241,348 252,909 1 There is no revaluation of net assets since the fair value of the same does not differ from their carrying value, which was previously recognized in the consolidated financial statements in the context of a joint venture. 2 The adjustments resulting from the acquisition relate primarily to the elimination of the net balance payable that the silos maintained with ImmunoTek. Such balances are the accumulated losses from the silos, which are allocated to ImmunoTek in accordance with the terms of the contract. The resulting goodwill is allocated to the Biopharma segment and includes the donor database, licenses and workforce. Finally, on 3 February 2025, Immunotek released three of the five warranties that Grifols Shared Services North America, Inc. (a wholly-owned subsidiary managed by the Grifols Group) had granted to Immunotek in June 2023 for certain leases related to certain Immunotek plasma collection centers outside of the collaboration under the Biotek America LLC joint venture. The remaining two guarantees, totaling approximately US Dollars 20 million, remain in force and are expected to remain in effect for as long as the leases remain in effect, with their balance being reduced as the lease term in question is reduced.

| If the acquisition had taken place on January 1, 2025, the Group’s revenue and net profit would not have changed, since the Group was already integrating those centers as a joint operation (see Note 10 of the consolidated annual accounts for the year ended December 31, 2024). (4) Financial Risk Management Policy Additionally to the main risks faced by the Group described in Note 30 of the consolidated annual accounts for the year ended December 31, 2024, during the first six months of 2025, the Group has identified new risk factors related to: • Potential tariffs on certain products in specific markets. The vertically integrated structure and the cross-licensing model that the Group presents in many of its locations offer Grifols flexibility and adaptability. • Regulatory changes in the United States that could affect the ability to set sales prices for our medical products, including legislative initiatives such as the One Big Beautiful Bill Act or the Delivering Most-Favored-Nation Prescription Drug Pricing to American Patients Act. To date, according to internal analysis, both risks are not considered to significantly impact the company's financial statements. The Group will continue to monitor the geopolitical environment and evaluate any possible impact of such measures.

| Impairment testing: CGUs correspond to the reporting segments except for the Others segment which corresponds to Kiro Grifols, Alkahest and GigaGen as separated CGUs. As a result of the acquisition of Talecris in 2011, and for impairment testing purposes, the Group combines the CGUs allocated to the Biopharma segment, grouping them together at segment level, because substantial synergies were expected to arise on the acquisition of Talecris, and due to the vertical integration of the business and the lack of an independent organized market for the products. Because the synergies benefit the Biopharma segment globally they cannot be allocated to individual CGUs. The Biopharma segment represents the lowest level to which goodwill is allocated and is subject to control by Group management for internal control purposes. As a result of the acquisition of Novartis’ Diagnostic business unit in 2014, the Group decided to combine Araclon, Progenika, Australia and Hologic’s share of NAT donor screening unit acquisition into a single CGU for the Diagnostic business as the acquisition is supporting not only the vertically integration business but also cross-selling opportunities. In addition, for management purposes, the Group’s management is focused on the business more than geographical areas or individual companies. In addition, due to the acquisition of the remaining 51% stake in Access Biologicals LLC in the year 2022, a new CGU for the Bio Supplies business was identified. The CGUs established by Grifols management are: • Biopharma • Diagnostic • Bio Supplies • Kiro Grifols • GigaGen • Alkahest There is no indication of impairment regarding the CGUs as of 30 June 2025.

Also, the control over the assigned credits, understood as the factor's ability to sell them to an unrelated third party, unilaterally and without restrictions, has been transferred to the factor. The main conditions of these contracts include the advanced collection of the assigned credits that vary between 70% and 100% of the nominal amount and a percentage of insolvency risk coverage on the factor side that varies between 90% and 100% of the nominal of the assigned credits. These contracts have been considered as non-recourse factoring and the amount advanced by the factors has been derecognized from the balance sheet. The finance cost of the receivables sold amounted to Euros 6,114 thousand for the six-month period ended 30 June 2025 and is recognized under "Finance costs" in the consolidated statement of profit and loss (Euros 13,685 thousand for the six-month period ended 30 June 2024) (see note 16).

The Group defers the changes in the forward element of forward contracts and the time value of option contracts in the costs of hedging reserve. The movement in this caption of the consolidated balance sheet during the six-month period ended at 30 June 2025 is reflected in the consolidated statement of changes in equity.

The Group's consolidated effective tax rate is 27%, excluding the effect of Biotest, for the six-month period ended 30 June 2025 and 25% for the six-month period ended 30 June 2024. Years open to inspection As established by current legislation, taxes cannot be considered definitively settled until the returns have been audited by the tax authorities, or the statute of limitations has elapsed. The Group is currently undergoing the following tax audits: • Certain companies of the Group domiciled in Spain were subject to an audit by the Spanish State Tax Administration Agency in relation to Corporate Income Tax for the years 2014, 2015 and 2016 and Value Added Tax for the years 2015 and 2016. On 8 November 2021, the Group agreed to the resulting assessments ("conformidad"). It should be noted that no penalties were imposed on any of the Group companies for any of the taxes subject to audit. Moreover and since these assessments have resulted in an adjustment in the allocation of taxable income between different jurisdictions and in light of their effect on the Group's Transfer Pricing, the Group now has a legal right to recover certain amounts from the corresponding Administration, in accordance with the provisions of the European Convention on the elimination of double taxation in connection with the adjustment of profits of associated enterprises.

| • Grifols Shared Services North America, Inc. and subsidiaries received in 2020 notification of a tax audit relating to the State Income Tax for the fiscal years 2017 and 2018. The U.S. Internal Revenue Service (“IRS”) has indicated that it intends to review the pricing of certain of the Group's cross-border transactions with its U.S. companies. Currently, the IRS is still at an early stage of its analysis and has only had initial discussions with the Group. • Certain Group companies domiciled in Spain are currently under audit by the Spanish State Tax Administration Agency in relation to Corporate Income Tax for the years 2017 to 2019 and Value Added Tax, personal income tax, non-resident income and capital income tax for the years 2018 and 2019. The Group disagreed to the corresponding assessment proposals ("disconformidad") and has received the corresponding final assessments, which have been appealed. No penalties were imposed on any of the Group companies for any of the taxes subject to these audit proceedings. As regards to Corporate Tax, the proposal is based on a difference in criteria in the valuation of certain transaction between Group companies. In relation to VAT, the proposal relies on a different interpretation of the financial activity carried out by the parent company of the Spanish tax Group and how such difference affects the deductibility of certain concepts. • On 2 and 5 June 2025, certain companies of the Group domiciled in Spain were notified of tax audits in relation to Corporate Income Tax for years 2020 to 2023, Value Added Tax and certain Personal Income Tax and Non-Resident Income Tax withholdings for years 2021 to 2023. During the six-month period ended June 30, 2025, the Group recorded a net provision of €21.062 million to cover potential liabilities related to uncertain tax treatments across all jurisdictions. Transfer pricing matters are complex, highly subjective and open to disputes involving different tax jurisdictions. The topics under discussion are complex and may take many years to resolve. The tax liability includes uncertain tax treatments that are estimated using either the most likely amount method or the expected value method and depend on the Group's assessment as to whether the approach taken by the Tax Authorities is likely to be sustained by Tribunals or Courts. Such assessment could change in the future depending on the progress of the review procedures by the Tax Authorities and the extent to which such procedures have been concluded. It may also be affected by the progress of ongoing claims and international procedures, which could result in the refund of taxes already paid under previously established settlements. Likewise, the assessment may vary due to changes in legal provisions or their interpretation, including the expiration of the corresponding statutory limitation periods. Management believes that it is unlikely that additional liabilities, above the amounts provided, will arise. Also, it is possible that the amounts provided may change and be partially, or even entirely, mitigated in future periods, as reviews, appeals or procedures challenging the Tax Authorities' approach progress or even the relevant statutes of limitation expire. Management continues to believe that the Group's position on all its transfer pricing, audits and disputes is robust, and that the Group has recognised appropriate tax provision balances, including consideration of whether corresponding relief will be available under applicable Mutual Agreement Procedures with the different countries. Minimum taxation (Pillar2 OECD) As of 30 June 2025, the Group continues to assess the implications of the OECD Pillar 2 reforms, which provide for the establishment of global minimum taxation rules; rules adopted in the EU through the relevant Directive to be transposed by Member States for application for financial years beginning on or after 1 January 2024. Beyond a significant increase in formal compliance burdens, the Group does not expect significant economic impacts from the application of this new regulation, as it is already subject to effective tax rates above 15%. In this context, the Group does not expect that the agreement reached with the U.S. will impact in any material manner its assessment of the impact of this new regulation. Thus, the Group expects that, in most of the territories in which it operates, it will benefit from the "transitional safe harbour" which allows the Group to prove that it complies with minimum taxation requirements, preventing additional top-up tax liabilities and alleviating formal compliance burdens. An exception to the above is Ireland, which has a nominal corporate income tax rate of 12.5% and has already passed its own Pillar 2 legislation which will allow it to levy corporate income tax directly.

Cash-settled share-based payment plan In May 2023, the Board of Directors of Grifols, S.A. approved a new long-term incentive plan based on restricted stock units (RSUs) aimed at certain members of the management team of the Company and its subsidiaries. The plan has a total duration of four years, where 50% of the RSUs granted will be settled at the end of the second year of the plan and the remainder at the end of the fourth year of the plan. As a condition for the vesting of the RSUs granted, each beneficiary must have remained continuously employed by Grifols on the settlement date of the plan. The RSUs will be settled in cash for an amount equivalent to the average price of the Class A shares during the five (5) business days prior to the settlement. In May 2025, 50% of the RSUs granted were settled, amounting to Euros 2,224 thousand. At 30 June 2025, the total accumulated amount is Euros 1,205 thousand as long-term in the heading “Provisions” (Euros 2,932 thousand as of 30 December 2024, of which Euros 2,090 thousand were short-term in the heading “Trade creditors and other accounts payable” and Euros 842 thousand were long-term in the heading “Provisions”).

| those of the shareholders and to support the long-term success of the company by promoting sustainable value creation, retaining key talent, and aligning with market standards. The potential beneficiary group includes approximately 35 individuals, of whom 11 are senior executives. Neither the CEO nor the CFO will be beneficiaries of the Plan. The plan has a three-year vesting period from the grant date and will be settled in Class A shares before 20 April 2028. Senior executives will receive 100% of their grant in the form of performance shares, while the remaining executives will receive 65% in performance shares and 35% in fidelity shares. The maximum number of shares to be delivered is 1,032,671, subject to the achievement of specific targets. For senior executives, 100% of the vesting of performance shares will depend on the relative Total Shareholder Return (TSR) compared to a predefined peer group. The plan includes performance thresholds and payout curves that allow for deliveries ranging from 0% to 150% of the target, depending on the level of achievement of the performance criteria. Savings plan and profit-sharing plan The Group has a defined contribution plan (savings plan), which qualifies as a deferred salary arrangement under Section 401 (k) of the Internal Revenue Code (IRC). Once eligible, employees may elect to contribute a portion of their salaries to the savings plan, subject to certain limitations. The Group matches 100% of the first 4% of employee contributions and 50% of the next 2%. Group and employee contributions are fully vested when contributed. The total cost of matching contributions to the savings plan was US Dollars 19 million as of 30 June 2025 (US Dollars 18.6 million as of June 30, 2024). Other plans The Group has a defined benefit pension plan for certain former Talecris Biotherapeutics, GmbH employees in Germany as required by statutory law. The pension cost relating to this plan is not material for the periods presented. The Biotest Group has established retirement benefits and employment commitments for certain employees, primarily from its German companies. These benefits are based on employees' length of service and salary. The pension plans are voluntary and are not subject to statutory or legal obligations. The amount of pension liabilities largely depends on fluctuations in interest rates and the life expectancy of the beneficiaries. d) Purchase commitments Purchase option on BPC Plasma Inc. and Haema GmbH Pursuant to the share purchase agreement dated 28 December 2018, the Grifols Group, through Grifols Shares Services North America Inc (for the shares of BPC Plasma Inc, formerly known as Biotest US Corporation ("BPC") and Grifols Worldwide Operations Limited (for the shares of Haema AG, now called Haema GmbH ("Haema")) (the "Selling Companies") sold 100% of the capital shares of BPC and Haema to Scranton Plasma B.V. ("Scranton"). The share purchase agreement includes an option for the Selling Companies to repurchase the shares, granting the Selling Companies an irrevocable and exclusive right (though not an obligation) to repurchase the shares sold to Scranton at any time following the sale, provided that when the option of the repurchase of the shares of a company (BPC or Haema, as the case may be) is exercise, the option for the repurchase of the other company (Haema or BPC, as the case may be) is also exercised simultaneously. The purchase option involves a fluctuating number of shares and a variable acquisition price. This characteristic classifies it as a derivative financial instrument that needs to be fairly valued, ultimately impacting the profit and loss account. The exercise price for the option will be determined based on the higher of the following two amounts: (i) the aggregate of the price at which the shares were sold to Scranton, increased by any expenses relating to the completion of the transactions contemplated in the relevant share purchase agreement, plus the increase in net working capital from the date of sale until the repurchase completion date resulting from the exercise of the repurchase option; and (ii) the amount required to pay in full the indebtedness that Scranton incurred with the lending entity to purchase the shares of Haema and BPC from the Selling Companies, for an amount of USD 425,000,000 along with any accrued interest and additional amounts required to fully repay that indebtedness.

| Based on the abovementioned contractual conditions, Grifols has estimated the value of the exercise of the repurchase option as follows: (i) the price at which the Selling Companies sold the shares to Scranton (totalling USD538,000,000) increased by any expenses relating to the completion of the transactions contemplated in the relevant share purchase agreement, plus (ii) the change in working capital. Based on the business models of Haema and BPC, this change in working capital is expected to primarily reflect the undistributed profits at the time of exercise of the repurchase option. Given that the price of the exercise of the repurchase option aligns closely with the fair value of BPC and Haema, this option's overall value is not considered significant. Furthermore, since the valuation of the option relies on unobservable market factors, it falls under Level 3 of the fair value hierarchy. In July 2024, Scranton entered into a loan agreement with funds controlled or managed by Oaktree (the "Loan Agreement") to refinance the loan that Scranton had initially obtained from banks in 2019. According to the terms of the Loan Agreement, this financing benefits from the following guarantees and security interest: (i) by a guarantee from BPC, (ii) a pledge of the shares of Haema and BPC, and (iii) pledges over the assets of BPC. In March 2025 and once the transformation of Haema into a limited liability company in the form of GmbH had concluded, following the terms of the Loan Agreement, Haema acceded to the Loan Agreement as a guarantor and granted security over its assets as collateral for the Loan Agreement. In the event of a default under the Loan Agreement, the Selling Companies can, respectively and simultaneously, exercise the repurchase option for both companies within 90 days after receiving notification of the default. If the Selling Companies fail to exercise this option within that timeframe, they will lose their right to repurchase the shares of Haema and BPC. As of 30 June 2025, no defaults have been reported under the Loan Agreement. In relation to the sale of the shares of BPC Plasma, Inc. and Haema GmbH, a loan was signed by Scranton Enterprises B.V. with the Group on 28 December 2018 for an initial amount of US Dollars 95,000 thousand (Euros 86,969 thousand). The remuneration is 2%+ EURIBOR and matures on December 2025. In 2023 an additional amount of Euros 15 million was arranged under the same conditions as the initial loan. As of 30 June 2025, the recorded amount stands at Euros 120,483 thousand, including accrued and capitalized interest to date (Euros 131,864 thousand as of 31 December 2024) (see note 10). Purchase option from Plasmavita Healthcare GmbH On November 22, 2017, the company Plasmavita Healthcare GmbH was incorporated in Germany. Currently, the Group is a shareholder of 50% of the shares and two individual partners, shareholders of the remaining 50% of the company's shares. Through a management services agreement, one of them (the "Managing Partner") provides certain management services to the company. The company's incorporation agreement establishes a purchase option in favor of the Group that grants the irrevocable right (not the obligation) to the Group to acquire the remaining 50% stake in the company from the two individual partners within a period of 6 months from the moment the Managing Partner ceases to provide the company's management services. The fair value of the purchase option is not material. National Service Projects Organization (NSPO) On 29 July, 2021, Grifols signed an agreement with the Egyptian company National Service Projects Organization (“NSPO”) through which Grifols and NSPO has incorporated a new entity in Egypt for the construction and operation of 20 plasma collection centers, a fractionation plant and a protein purification and dosing plant. Grifols and NSPO hold 49% and 51% respectively in the new entity. The agreement includes a call option and a put option for both shareholders which allows them to acquire or sell their entire stake to the counterparty. These options can be exercised once the 10-year period from the creation of the company has elapsed. As the options are based on a variable number of shares and a variable amount, there is a derivative financial instrument that shall be measured at fair value through profit or loss. Given that the option price has been set at a value similar to the fair value of the new entity, the options do not have a significant value. GRIFOLS, S.A.

| Canadian Blood Services In June 2022, Grifols signed a collaboration agreement with Canadian Blood Services (CBS) to supply them with 2.4 million grains of Immunoglobulin exclusively through a network of Canadian plasma centers, that should be fully developed and operational by July 2026. To achieve this goal, Grifols will need to collect 600.000 liters of Canadian plasma annually from Grifols-owned plasma centers in Canada. For this reason, Grifols has assumed the following commitments for the acquisition of plasma and self-built centers in Canada: Euros 2025 2026 2027 7,737,725 4,804,803 32,572,014 e) Contractual commitments Agreement on the sale of the 20% shareholding in SRAAS As a consequence of the agreement to sell the 20% shareholding in Shanghai RAAS to Haier, both companies signed the following agreements: • The existing Exclusive Distribution Agreement for human serum albumin for the Chinese market, signed with SRAAS, will have a duration of 10 years (until 2034), with a 10-year extension option by SRAAS and guaranteed minimum supply volumes for the period 2024-2028. In the absence of an agreement for subsequent years, the minimum volumes agreed for 2028 will apply. Pricing under such an agreement will remain at the same applicable standards. • Grifols commits to achieve an aggregate GDS's Group EBITDA of US Dollars 850 million for the period 2024-2028 under condition that Haier owns no less than 10% of SRAAS. In the event of a breach of this commitment, it will compensate SRAAS with cash in 2029 for the multiplier resulting from the shortfall and the capital ownership that SRAAS' current holds in GDS. Based on the most pessimistic projections for the GDS Group, the probability of deviation is very low and therefore no liability was considered at the closing of the sale transaction. This commitment is assessed at the end of each year during the commitment period. • Grifols undertakes that, for so long as it controls GDS directly or indirectly, it will use its commercially reasonable efforts, without obligation, to ensure that GDS declares and distributes dividends to its shareholders in each year after closing in an amount not less than 50% of the net profits of GDS for that year. • Grifols has pledged its shares in SRAAS in favour of Haier (on behalf of Haier and SRAAS), to secure the cash pooling agreement between GDS, as debtor, and Grifols, as creditor. • Grifols retains the right to appoint a director to the board of directors of SRAAS. However, Grifols has granted Haier (a) a voting proxy for 10 years and (b) a right of first refusal in case Grifols wishes to sell these shares. The voting proxy agreement has been valued at Euros 10 million, which will be amortized over 3 years as this is the period during which Haier and Grifols have agreed not to transfer their shares in SRAAS. As of 30 June, 2025, an income of Euros 1,739 thousand has been recognized in the Consolidated Statements of Profit and Loss (nothing as of 30 June, 2024). GRIFOLS, S.A.

| f) Judicial procedures and arbitration The information about legal proceedings in which Grifols or companies of the Group are involved is the following: • EXECUTIVE COMMITTEE OF CNMV On September 25, 2024, Grifols received notification that the Executive Committee of CNMV had initiated an administrative sanctioning procedure in connection with the conclusions reached by the CNMV on March 21, 2024. These conclusions were disclosed by the Company as Inside Information on the same date and subsequently supplemented. The proposed sanction against Grifols for the incidents mentioned in the conclusions and supplementary information does not exceed one Million Euros. On 7 November, 2025, Grifols submitted allegations against the initiation of the administrative sanctioning procedure. On 16 May, 2025 Grifols requested the CNMV to conclude the administrative procedure, which concluded with the resolution of the CNMV on 25 June, 2025, initiating a two-month period to commence the contentious-administrative procedure before the National High Court. • ADDITIONAL LITIGATION There a several recently filed wage and hour and related labor law class actions and/or California Private Attorneys General Act lawsuits that have been filed in California. These cases are in the very early stages and it is not yet known what the probability is that any of the cases can result in any potential relevant cash outflow for the Group. Based on past litigation and results, Grifols asserts that it is possible that one or more cases can reach to a material level in the future given the allegations of wage and hour violations, but at this time it is not probable to occur. In any case, Grifols will vigorously defend itself, and as part of its internal process, it will continue to asses, on a timely basis, any changes in facts and circumstances that may modify its risk evaluation. In the event that any of these contingencies becomes more probable, it will determine whether they could result in a material cash outflow.

| The Management Report for the six-month period ended June 30, 2025, should be read in conjunction with the consolidated financial statements for the same period and related notes. The comments and analyses included in the report may contain forward-looking statements and considerations that involve risks and uncertainties - refer to the section "Risks and uncertainties" at the end of this report. For Grifols, the first six months of 2025 are testament of the continued progress on key fronts, including growth, profitability, cash flow generation and deleveraging, while remaining focused on achieving its financial and operational targets. The company is successfully executing on its Value Creation Plan, being on track with the implementation of several initiatives, levering on commercial growth, margin expansion and pipeline execution, enabled by its plasma supply and industrial network, as well as innovation. EVOLUTION OF REVENUES BY BUSINESS UNIT In this context, Grifols’ revenue reached EUR 3,677 million in the first six months of 2025, representing an increase of 7.0% cc1 (+6.8% reported2 ). In the second quarter of the year, revenues were up to EUR 1,891 million, up by +6.6% cc and +4.0% reported mainly driven by the Biopharma business unit. Biopharma Biopharma’s revenues increased by 8.2% cc (+7.9% reported) to EUR 3,154 million in the first six months of the year (+11.8% cc and +11.6% reported on a LFL basis), driven by a strong second quarter of EUR 1,633 million up by +9.6% cc and +6.9% reported. The main growth levers were the solid performance of key proteins in key markets driven by robust underlying demand. Worth noting is the robust sales growth of immunoglobulins, representing around 60% of Biopharma revenues, which grew by 12.5% cc (+17.8%cc LFL), fueled by strong demand for intravenous immunoglobulin (IVIG) and the significant growth of subcutaneous immunoglobulin (SCIG) Xembify® at 66.3% cc. In the first half of 2025, Grifols continued to strengthen its immunoglobulin franchise by focusing its efforts on the fastest-growing immunodeficiency segments, including primary (PID) and secondary (SID) immunodeficiencies, while maintaining its leadership in neurology and intensive care. The company aspires to continue to drive the growth of this franchise while accelerating the expansion and penetration of Xembify® , for which demand continues to increase in geographies quarter-over-quarter. Sales of albumin were down by 3.7% cc in H1’25 and Alpha-1 and specialty proteins were up by 4.8% cc, with the former benefiting from the specialty pharma distributor transition. Diagnostic In the first six months of 2025, Diagnostic recorded revenues of EUR 332 million, increasing by 2.8% cc (+2.8% reported) and of EUR 162 million in the second quarter, up by +0.4% cc (-1.6% reported). Blood typing solutions (+7.1% cc) continued to be the main driver, with growth across main countries, including the U.S., LATAM and EMEA. Bio Supplies Bio Supplies was down by 31.8% cc (-31.5% reported) to EUR 69 million in the first half of the year, affected by a second quarter of EUR 36 million down by -49.3% cc (-50.6% reported). The year represent significant growth in the business through capitalizing on its momentum and maximizing the value of its product portfolio. PLASMA SUPPLY AND COST PER LITER GRIFOLS, S.A. AND SUBSIDIARIES Consolidated Director’s Report for the six-month period ended June 30, 2025 40 1 Operating or constant exchange rate (cc) excludes exchange rate variations for the period. 2 Reported includes the impact of foreign exchange rates.

| Grifols continues to efficiently manage its plasma supply and reduce its cost per liter (CPL), leading to significant increases in profit margins. Significant effort continues to be placed to meet the increasing demand for products while simultaneously managing inventory levels to effectively grow the business while optimizing consumption of working capital. The improvement QoQ and sequentially throughout the year highlight this. As of June 30, 2025, individualized nomogram has been implemented at a 60% in the U.S. centers and the second wave has kicked-off, which will allow the company to reach 100% adoption by 2026. As a result of this and additional continuous improvement projects, manufacturing yield is higher. The company currently operates the largest private plasma supply network in the world, and continues to progress on its optimization. Approximately one quarter of all donor centers are outside the U.S. This is the largest network of donor centers ex-US within the industry – the recent expansion of donor centers in Egypt through the joint business with Egypt's NSPO (National Service Projects Organization por sus siglas en inglés) and Canada are key to growth supplementing the large number of donor centers in Germany and Eastern EU. FINANCIAL RESULTS In the first half of 2025, gross margin increased to 39.1% (37.8% in PY), mainly driven by strong revenue growth and lower cost per liter of plasma (CPL) as a result of various continuous improvement initiatives. Adjusted EBITDA reached EUR 876 million in the first half of 2025, representing a margin of 23.8% on revenues, improving compared to 23.0% in PY. Reported EBITDA stood at EUR 836 million (22.7% margin). The sequential margin expansion throughout the year is reflected in an adjusted EBITDA of EUR 400 million (22.4% margin) in the first quarter and EUR 475 million (25.1% margin) in the second quarter. This is supported by the growth of Biopharma, cost optimization and operating leverage. The financial result stood at EUR 312 million loss in H1’25, lower compared to the EUR 389 million loss in PY, which contributed to a higher reported net income of EUR 177 million (EUR 36 million in 2024). BALANCE SHEET On June 30, 2025, total assets stood at EUR 19,767 million, compared with EUR 21,405 million as of December 31, 2024. Inventory control, collection, and payment periods Inventories totaled EUR 3,347 million with a turnover of 272 days (294 days in December 2024) due to the progressive impact of the improved cost per liter of plasma in a context of increased supply. Average collection and payment periods remained stable at 37 days (36 days in 2024) and 58 days (61 days in 2024) (all these figures include Biotest except for average payment period). For more information regarding Grifols' supplier payment practices, see the section “Political commitment and activities with advocacy groups” in the Consolidated Non-Financial Information and Sustainability Statement for fiscal year 2024. Working capital management Improvements in working capital management continue to optimize Grifols’ financial structure. As of June 30, 2025, working capital consumption stood at EUR -260 million dragged by receivables and more consumption of inventories in the first quarter. Deleveraging commitment Deleveraging remains a core priority for Grifols, which reiterates its aim of reducing debt on its balance sheet. At the close of June 30, 2025, the debt ratio fell to 4.2x (4.6x in December 2024; under the Credit Agreement, see reconciliations in the Annex) following EBITDA improvements and operating cash flow generation, which stood at EUR 291 million in the first half of 2025 GRIFOLS, S.A. AND SUBSIDIARIES Consolidated Director’s Report for the six-month period ended June 30, 2025 41

| Evolution of equity On June 30, 2025, shareholder equity totaled EUR 5,260 million. Grifols’ share capital is represented by 426,129,798 ordinary shares (Class A), with a nominal value of EUR 0.25 per share, and 261,425,110 non-voting shares (Class B), with a nominal value of EUR 0.05 per share. Grifols ordinary shares (Class A) are listed on the Spanish Stock Market and form part of the IBEX-35 (GRF) and non-voting shares (Class B) are listed on the Spanish Stock Market (GRF.P). Grifols Class A and B shares are also listed on NASDAQ (GRFS) through ADRs (American Depositary Receipts). CASH FLOWS AND CAPITAL RESOURCES Cash flow generation in the first six months of 2025 is marked by sequential improvement. The robust performance was due to active and efficient management of working capital, including inventory, accounts receivables and payables. Financial discipline in CAPEX spending also contributed. Cash flows from operating activities In H1’25, net cash flows from operating activities continued their positive trend fueled by solid business performance and the effective implementation of the operational improvement plan announced at the onset of 2024. Operating cash flows reached EUR 291 million (EUR 88 million in H1’24). Cash flow from investing activities Net cash flows consumed from investment activities totaled EUR -305 million (EUR 1,261 million in H1’24), the most significant of which was capital expenditures (CAPEX). These were focused primarily on Biopharma’s new production facilities, of note investments in the plasma fractionation, immunoglobulin purification and albumin plants in Montreal (Canada), as well as in the new albumin plant in Dublin. Cash flow from financing activities Cash flow from financing activities totaled EUR -315 million (EUR 225 million in H1’24). Capital resources and credit ratings On June 30, 2025, Grifols’ net financial debt was EUR 7,992 million, excluding the impact of IFRS 163 . In the first six months of 2025, the company has continued to actively reduce its leverage ratio mainly organically through EBITDA improvement. Net financial debt to EBITDA ratio stood at 4.2x (4.6x as of December 31, 2024) in accordance with the Credit Agreement (see Annex for reconciliation). Furthermore, Grifols continued to optimize its financial structure. At the close of this report, close to 75% of Grifols’ debt is linked to fixed interest rates. While there are no significant debt maturities before May 2027 and no periodic financial covenants, this financial structure lessens the impact of interest rate rises. CAPITAL EXPENDITURES (CAPEX) Grifols advanced its capital investment plan to expand and improve the production facilities of its business units. The company has notably optimized its CAPEX resource allocations considering the investments already made in recent years. In 2024, capital expenditures related to PP&E additions stood at EUR 123 million (EUR 260 million as of December 31, 2024). Prior investments have well positioned the company to satisfy its growth and expansion. GRIFOLS, S.A. AND SUBSIDIARIES Consolidated Director’s Report for the six-month period ended June 30, 2025 42 3 On June 30, 2025, the impact of the application of IFRS 16 on debt is EUR 1,089 million

| Joining forces with Inpeco to deliver transfusion medicine ‘lab of the future’ In March, Grifols announced that it is strategic agreement with Inpeco, a global leader in total laboratory automation technologies, to provide transfusion medicine labs with complete, tailored instrumentation, robotics and software capabilities to modernize their operations and make them more efficient. As part of their collaboration, the two companies are exploring areas in which their combined engineering expertise could deliver more value to transfusion medicine laboratories, which could include technologies that focus on sample pooling, analysis and transport. Partnership with IBL International to develop advanced biomarker panels for unique clinical diagnostics platform In April, Grifols announced it will expand its offer in clinical diagnostics through a strategic partnership with IBL International GmbH, a leader in specialty diagnostics. Together the two companies aim to change the clinical diagnostics landscape. Their collaboration will provide clinical laboratories with Grifols’ highly sensitive multiplexing instrumentation running IBL’s assays customized exclusively for the Grifols platform. INNOVATION Submission of Biologics License Application for new fibrinogen solution to U.S. FDA n January, Grifols has submitted a Biologics License Application (BLA) for its new potential fibrinogen treatment to the United States Food and Drug Administration (FDA). The European equivalent, a Marketing Authorization Application (MAA), was submitted for several countries in October 2024. Grifols expects to begin treating patients in Europe starting in the second half of 2025, with rollout in the U.S. planned for the first part of 2026. Pioneering high-tech analysis of plasma bank to detect early signs of Parkinson’s disease In January, Grifols received a grant from The Michael J. Fox Foundation for Parkinson’s Research (MJFF) to identify plasma-based biomarkers that could indicate a person’s likelihood of developing Parkinson’s disease (PD) many years before clinical diagnosis. The initiative, called “Chronos-PD,” could accelerate the discovery of new diagnostic tools as well as the identification and development of novel disease-modifying therapeutics. The $21 million award will fund a pilot study to analyze longitudinal plasma samples covering a period of up to 10 years. This will enable researchers to track how distinct plasma proteins evolve over time in people with PD, which could help establish an early-warning system for the emergence of the disease. Completion of enrollment of second cohort in first-in-human Alpha-1 15% subcutaneous option for treating alpha1- antitrypsin deficiency In February, Grifols finished recruiting the second cohort of its Phase 1/2 study (NCT04722887) evaluating the safety and tolerability of two different doses of Alpha1-Proteinase Inhibitor Subcutaneous (Human) 15% (Alpha-1 15%) as a subcutaneous (SC) option for the treatment of alpha1-antitrypsin (AAT) deficiency, compared to Liquid Alpha1-Proteinase Inhibitor (Human) intravenous (IV). A clearance of IND application for Phase 2 trial of immunoglobulin drops for dry eye disease In May, the United States Food and Drug Administration (FDA) cleared the company’s Investigational New Drug (IND) application to initiate a Phase 2 trial evaluating its immunoglobulin (IG) drops – GRF312 Ophthalmic Solution – for what could become the first-ever ocular surface indication for an IG and a potential new treatment for dry eye disease (DED). Positive fibrinogen phase 3 trial results published in The Lancet’s eClinicalMedicine In June, Grifols announced that the positive Phase 3 study data on its fibrinogen concentrate, BT524, has been published in eClinicalMedicine, a peer-reviewed journal published by The Lancet Discovery Science Suite. The article highlights that the trial met its primary endpoint, demonstrating that treatment with BT524 is non-inferior to standard of care (SOC) with cryoprecipitate or fresh frozen plasma (FFP) in reducing clinically relevant intraoperative bleeding in patients with acquired fibrinogen deficiency (AFD) undergoing planned major spinal or abdominal surgery.

| OTHER INFORMATION Treasury stock The transactions carried out with treasury stock during 2024 are set out in the notes to the consolidated financial statements attached to this report. As of June 30, 2025, Class A treasury shares totaled 3,944,430 and Class B treasury shares amounted to 3,844,430 shares. Risks and uncertainties Additionally to the main risks faced by the Group described in Note 30 of the consolidated annual accounts for the year ended December 31, 2024, during the first six months of 2025, the Group has identified new risk factors related to: • Potential tariffs on certain products in specific markets. The vertically integrated structure and the cross-licensing model that the Group presents in many of its locations offer Grifols flexibility and adaptability. • Regulatory changes in the United States that could affect the ability to set sales prices for our medical products, including legislative initiatives such as the One Big Beautiful Bill Act or the Delivering Most-Favored-Nation Prescription Drug Pricing to American Patients Act. To date, according to internal analysis, both risks are not considered to significantly impact the company's financial statements. The Group will continue to monitor the geopolitical environment and evaluate any possible impact of such measures Subsequent events Apart from the subsequent events in Note (22) of the Group's Condensed Consolidated Interim Financial Statements, there are no additional relevant subsequent events that are relevant to add. Foreseeable evolution of the group Building on our strong foundations and clear momentum, Grifols is executing on its Strategic Plan focused on profitable growth, profitability improvement, cash flow generation and disciplined capital allocation to unlock its full potential. Biopharma will continue to be the main growth engine, levering on commercial excellence, margin expansion and pipeline execution, capitalizing on its diversified plasma network and strong innovation. ENVIRONMENT, SOCIAL, AND GOVERNANCE (ESG) ISSUES Promoting sustainability continues to be the cornerstone of Grifols’ long-term business model with environmental, social and corporate governance (ESG) at its core. In its quest for sustainable growth and further strengthening its robust industry status, the company raised its excellence in (ESG) practices. As the company advances its sustainability goals, it remains focused on driving long-term value and making a lasting impact toward a more sustainable, ethical and resilient future for all stakeholders.

| ANNEX - NON-GAAP (IFRS-EU) MEASURES RECONCILIATION OR ALTERNATIVE PERFORMANCE MEASURES (APM) To complement the consolidated financial statements presented in accordance with International Financial Reporting Standards (IFRS), Grifols provides the following tables and reconciliations. These tables contain APM measures, which are used in conjunction with financial metrics in accordance with IFRS. Their purpose covers budget setting, business management, operational and financial performance evaluation, as well as comparison with prior periods and competitors. The inclusion of these measures is useful as it allows for analysis and comparison of profitability and solvency across companies and industries, eliminating accounting and financial effects that are not directly related to cash flows. In addition, Grifols presents non-financial measures because they are commonly used by investors, securities analysts, and other market players. These measures complement the analysis of financial performance and should be considered in conjunction with IFRS metrics, not as a replacement for them. The following tables set out the measures and ratios commonly used by Grifols, including their name, purpose and, in the case of ratios, how they are calculated. Alternative Performance Measures Definition Aim / Purpose Revenue at constant currency Reported revenue + variation due to exchange rate impact Excludes fluctuations in the exchange rates of the different currencies in which Grifols reports revenues in order to facilitate to facilitate the comparison between different financial periods and the understanding of their evolution. Earnings Before Interest, Tax, Depreciation and Amortization (EBITDA) or Gross Operating Profit Operating profit + depreciation, amortization and provisions El EBITDA (“Earnings Before Interest, Tax, Depreciation and Amortization”) evaluates operating results without taking into account large expense items that have no impact on cash flows. This metric provides a more accurate and comparable understanding of the company's performance. GRIFOLS, S.A. AND SUBSIDIARIES Consolidated Director’s Report for the six-month period ended June 30, 2025 47

| EBITDA adjusted Same as above + extraordinary costs - extraordinary revenues For more information about these extraordinary amounts, see reconciliation tables below. More accurately reflects the company's organic performance, including or excluding certain non-recurring amounts, see detail below: - Restructuring costs: in 2023 and 2024 the company incurred a set of extraordinary costs in order to significantly reduce its cost structure following the impact of COVID-19. In this regard, in 2022 the company implemented a comprehensive operational improvement plan ("Operational Improvement Plan") designed to strengthen its competitiveness and create a leaner and more efficient organization. This plan is estimated to achieve annual cost savings of more than 450 million euros. The result of this initiative translates into a significant reduction in the company's total cost base, an improvement in its operating cash flow, and the establishment of a more dynamic and efficient operating model. This is the first time the company has implemented such a plan. These impacts have been considered of a non-recurring nature because it is not a plan that is carried out on an annual basis, as well as for its own extraordinary nature. These costs decrease as 2024 progresses, until they cease to occur in 2025. - Transaction costs: in 2024 transaction costs are related to the strategic transaction in China with Haier Group, through which it will sell approximately a 20% stake in Shanghai RAAS to Haier for approximately USD 1.8 billion. The extraordinary nature of this transaction must be taken into account in the context of the company's leverage. Mainly linked to this, in 2024 we accounted transaction costs of €49m. In 2025, these costs are mainly related to this transaction and with the Biotest delisting. -Impairments: in 2024 it is linked with Biopharma and in 2025 with Biotest. -Biotest Next Level (BNL) project: in 2024 and 2025, this refers to a specific project aimed at increasing Biotest's production capacity in Dreieich, Germany. GRIFOLS, S.A. AND SUBSIDIARIES Consolidated Director’s Report for the six-month period ended June 30, 2025 48

| It has been decided to adjust the costs strictly related to this project due to the extraordinary and non-recurring nature of this project due to the high investment in terms of operating expenses required to start up the company's production facilities. Failure to adjust for this impact would distort the picture of the company's level of recurring operating expenses. Other Non-Recurring Items: part of these one-offs were related to costs as a consequence of the short-seller attack.
