AND SUBSIDIARIES Notes to the Condensed Consolidated Interim Financial Statements for the six-month period ended 30 June 2024 2 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 2024 and, accordingly, have been considered for the preparation of these condensed consolidated interim financial statements: Standards IASB effective date EU effective date IAS 1 Amendments to IAS 1 Presentation of Financial Statements: • Classification of Liabilities as Current or Non-current Date (issued on 23 January 2020); • Classification of Liabilities as Current or Non-current - Deferral of Effective Date (issued on 15 July 2020); and • Non-current Liabilities with Covenants (issued on 31 October 2022) 1 January 2024 1 January 2024 IFRS 16 Amendments to IFRS 16 Leases: Lease Liability in a Sale and Leaseback (issued on 22 September 2022) 1 January 2024 1 January 2024 IAS 7 Amendments to IAS 7 Statement of Cash Flows and IFRS 7 Financial Instruments: Disclosures: Supplier Finance Arrangements (Issued on 25 May 2023) 1 January 2024 1 January 2024 Mandatory application for annual periods beginning on or The application of these standards and interpretations has had no significant impact on these condensed consolidated interim financial statements. At the date of preparation of these condensed consolidated interim financial statements, the following IFRS, amendments and IFRIC interpretations have been issued by the IASB, but not adopted by the European Union for their application in Europe: 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 Pending IFRS 9 Amendments to the Classification and Measurement of Financial Instruments (Amendments to IFRS 9 and IFRS 7) (issued on 30 May 2024) 1 January 2026 Pending IFRS 19 Subsidiaries without Public Accountability: Disclosures (issued on 9 May 2024) 1 January 2027 Pending IFRS 18 Presentation and Disclosure in Financial Statements (issued on 9 April 2024) 1 January 2027 Pending Mandatory application for annual periods beginning on or 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 accounting policies The information in these condensed consolidated interim financial statements for the six-month period ended June 30, 2024 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 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

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Condensed Consolidated Interim Financial Statements for the six-month period ended 30 June 2024 3 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. • Evaluation of the capitalization of development costs (see note 4(d) to the consolidated annual accounts for the year ended December 31, 2023). The key assumption is related to the estimation of the technical and economic feasibility 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, 2023). • 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, 2023). • The assumptions used for the calculation of the fair value of financial instruments (see note 3, 29 and 30 to the consolidated annual accounts for the year ended December 31, 2023). • 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 (see note 10 and 19 to the consolidated annual accounts for the year ended December 31, 2023). • 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 20). 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, 2023, and for the six month ended June 30, 2024. (c) Comparative financial information Grifols' condensed consolidated interim financial statements for the six months ended June 30, 2024 show comparative figures as of December 31, 2023 for the consolidated balance sheet and the six months ended June 30, 2023 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. As a result of what is explained in the following section, the comparative figures of January 1, 2023, are additionally included in compliance with IAS1.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Condensed Consolidated Interim Financial Statements for the six-month period ended 30 June 2024 4 (d) Changes in accounting criteria and correction of errors The financial information as of December 31, 2023, which is presented for comparison with that of June 30, 2024, differs from that approved by the Ordinary General Meeting of Shareholders of the Parent Company on June 14, 2024 for the reasons set out below. Biotek America LLC In July 2021, Grifols entered into a collaboration agreement with ImmunoTek GH, LLC (ImmunoTek) to open and manage plasma donation centres. The transaction was implemented through the joint creation of a company in the United States, Biotek America LLC ("ITK JV"), which created a series of shares for each centre. Until 2022, Grifols had recognised its interest in the ITK JV as a financial investment. In 2024, following discussions with the Spanish National Securities Market Commission (CNMV), it was concluded that this agreement should be recognised as a joint operation and therefore the assets, liabilities and results of the jointly controlled entity should be recognised. Consequently, in the consolidated annual accounts at December 31, 2023, the assets and liabilities of the joint operation were integrated in the amount of Euros 151,780 thousand and Euros 190,262 thousand, respectively, recognising a negative adjustment in reserves of Euros 38,482 thousand and translation differences of Euros 862 thousand. The integration was carried out prospectively from January 1, 2023. This negative adjustment to reserves relates mainly to the losses of Biotek America, LLC in 2021, 2022 and 2023. To accurately present these losses in the respective income statements for each period, the comparative figures for the first half of 2023 have been restated in the condensed consolidated interim financial statements for the first half of 2024. This restatement impacted net income, reducing it by Euros 13,878 thousand. Likewise, the comparative figures corresponding to the income statement for 2023 and 2022 will be restated, which will be presented in the consolidated financial statements for 2024, the impact of which represents a reduction in results of Euros 16,997 thousand and Euros 23,244 thousand, respectively. Shanghai RAAS On March 30, 2020, Grifols received shares of Shanghai RAAS Blood Products Co. Limited (hereinafter, "SRAAS") corresponding to 26.2% of its share capital in exchange for having previously delivered shares representing 45% of the economic rights of its subsidiary Grifols Diagnostic Solutions, Inc. (hereinafter "GDS") under the swap agreement entered into with SRAAS in 2019. Grifols therefore held a stake in an associate which in turn holds a stake in the GDS subsidiary. Since International Financial Reporting Standards (IFRS) do not address the accounting treatment of non-controlling interest when an investment in an associate has a stake in a Group company, Grifols chose the accounting policy to (i) increase the percentage of ownership attributable to Grifols in GDS by the indirect interest Grifols obtained through its stake in SRAAS by 11.79% (26.2% of 45%), thereby reducing the non-controlling interest by that percentage, and (ii) exclude any amount recognized by SRAAS for its stake in GDS from the equity-method investment in SRAAS, as Grifols consolidates 100% of the GDS net assets. Consequently, due to the accounting policy adopted in March 2020, Grifols had an attributable stake of 66.79% (55% + 11.79%) in GDS, while the non-controlling interest was reduced from 45% to 33.21% amounting to Euros 403 million. This reduction in net equity attributable to the non-controlling interest was offset against consolidated reserves because it was a transaction with minority shareholders without loss of control. As a result of selling the 20% equity stake in SRAAS in 2024 (see note 9) and during the limited review as of June 30, 2024, it has been identified that the initial recognition of the investment in SRAAS should have excluded the amount that SRAAS held in GDS according to Grifols’ accounting policy at the transaction date, amounting to Euros 457 million. Therefore, the reduction in equity attributable to non-controlling interest should have decreased the investment in equity-accounted investee in SRAAS recognized in March 2020 instead of affecting consolidated reserves. Consequently, both the stake in SRAAS and consolidated reserves are overvalued by Euros 457 million for the years 2020 to 2023.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Condensed Consolidated Interim Financial Statements for the six-month period ended 30 June 2024 5 The difference between the Euros 457 million and the Euros 403 million initially recorded corresponds to the revaluation of the indirect stake that Grifols acquires in GDS through its stake in SRAAS. This adjustment entails a reduction in consolidated reserves as it is a transaction with a minority shareholder without loss of control. In this context, the amounts related to ‘Investment in equity-accounted investees’, ‘Non-current assets held for sale,’ and ‘Consolidated reserves’ as of December 31, 2023, have been restated in the comparative information, decreasing by Euros 113 million, Euros 344 million, and Euros 457 million, respectively. Despite this correction resulting in a reduction of equity by €457 million, it has had no impact on the income statement; it represents an incorrect accounting treatment without affecting the correct results for each affected financial year. Therefore, the results recognized in the equity-method investment in SRAAS and the results attributable to both the Parent Company and the non-controlling interest in GDS in the consolidated annual accounts from 2020 to 2023 are correctly accounted for. Additionally, following this correction, which decreased the carrying value of the investment in SRAAS, the net gain recorded from the sale of the 20% stake in SRAAS is accurately accounted for in the 2024 financial statements. The following tables summarize the impacts on the comparative information in the Consolidated Summary Balance Sheet and in the Consolidated Summary Income Statement due to the above: Biotek America SRAAS Restated Assets 01/01/2023 Intgration adjustment Adjustment 01/01/2023 Rights of use 897,552 83,708 -- 981,260 Property, plant and equipment 3,270,937 31,921 -- 3,302,858 Investments in equity-accounted investees 1,955,177 -- (457,218) 1,497,959 Non-current financial assets 582,175 (124,132) -- 458,043 Other non-current assets -- 124,191 -- 124,191 Total non-current assets 16,880,390 115,688 (457,218) 16,538,860 Inventories 3,201,357 34,653 -- 3,236,010 Trade and other receivables 608,688 393 -- 609,081 Other current assets 81,814 863 -- 82,677 Cash and cash equivalents 547,979 1,228 -- 549,207 Total current assets 4,653,587 37,137 -- 4,690,724 Total assets 21,533,977 152,825 (457,218) 21,229,584 Consolidated Balance Sheet at 1 January 2023 (Expressed in thousands of Euros)

(f) 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 Composition of the Group 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 December 31, 2023 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 June 30, 2024, are detailed below: • Biotest Italy, S.R.L. With effect as of January 1, 2024, Biotest Italy, S.R.L. and Grifols Italia S.p.A. entered into a merger agreement, with Grifols Italia S.p.A. being the surviving company.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Condensed Consolidated Interim Financial Statements for the six-month period ended 30 June 2024 8 • Biotest Medical, S.L.U. With effect as of January 1, 2024, Biotest Medical, S.L.U. and Grifols Movaco, S.A. entered into a merger agreement, with Grifols Movaco, S.A. being the surviving company. • Biotest Farmaceutica LTDA With effect as of February 1, 2024, Biotest Farmaceutica LTDA and Grifols Biotest Ltda entered into a merger agreement, with Grifols Biotest Ltda being the surviving company. • Biotest France SAS With effect as of March 1, 2024, Biotest France SAS and Grifols France S.A.R.L entered into a merger agreement, with Grifols France S.A.R.L being the surviving company. • Plasma Centers – Immunotek As a result of the collaboration agreement entered to ImmunoTek GH, LLC, on April 1, 2024, Grifols has acquired 7 silos, one for each plasma center (see note 9). This transaction has meant that Grifols obtains control of the 7 acquired centers (business) that were previously considered within the joint operation. Therefore, Grifols has applied the requirements for a business combination carried out in stages, including the measurement of its previously held interest in the joint operation at fair value at the acquisition date. However, considering that (i) Grifols' effective participation in the joint operation is null and (ii) all assets and liabilities related to the joint operation are already recognized in the consolidated financial statements, the difference between the consideration paid, net of advances, for the plasma centers and the fair value of the assets and liabilities, which does not differ from its carrying amount, 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: Thousand of euros Thousand of US Dollars Cash paid 124,673 135,547 Current assets 6,086 6,308 Non current assets 27,873 28,889 Current Liabilities (6,603) (6,844) Non current liabilities (27,539) (28,543) adjustments resulting from the integration prior to obtaining control (8,677) (8,993) Goodwill (excess of the cost of the business combination over the net assets) (note 6) 115,813 126,364 The resulting goodwill has been allocated to the Biopharma segment and includes the donor database, licenses and workforce. (4) Financial Risk Management Policy At June 30, 2024, the Group maintains the same financial risk management policies and objectives at December 31, 2023.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Condensed Consolidated Interim Financial Statements for the six-month period ended 30 June 2024 9 In this context, the Group has actively worked to implement its deleveraging plan by taking the following actions: • On April 23, 2024, a private placement of Euros 1,000 million of senior secured bonds was made and, on June 4, 2024, an additional placement of Euros 300 million of senior secured bonds. The funds received have been used for the redemption of senior unsecured notes maturing in May 2025 and the remainder was used for the partial repayment of the revolving facility (RCF) (see note 15). • On June 18, 2024, the sale of the 20% shareholding in Shanghai RAAS to Haier was completed and these funds will be used to partially amortize the senior debt secured on a pro rata basis. Likewise, in accordance with the debt contracts, the Group must meet certain financial ratios. As of June 30, 2024, the Group complies with the financial ratios established in the contract.

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 vertical integration of the 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.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Condensed Consolidated Interim Financial Statements for the six-month period ended 30 June 2024 17 The main movements of the entities valued by the equity method with activity similar to that of the Group are explained below: Shanghai RAAS Blood Products Co. Ltd. On December 29, 2023, Grifols reached an agreement with Haier for the sale of a 20% shareholding subject to regulatory approvals and other conditions agreed in the agreement. As a result of the Share Purchase Agreement, at December 31, 2023 the amount equivalent to 20% of the shareholding in SRAAS was reclassified to Non-current assets held for sale for Euros 1,089,856 thousand (see note 11). On June 18, 2024 the sale transaction was closed and Grifols loses its significant influence over its interest in SRAAS at the closing of the transaction. The remaining 6.58% interest in the shares of SRAAS is considered a financial asset measured at fair value through "Other comprehensive income" at the transaction date and has been reclassified to financial asset (see note 10 and 11). In the first half of 2024, dividends of RMB 52,984 thousand, equivalent to Euros 6,724 thousand, were received. Joint operation: Biotek America, LLC Grifols has signed a collaboration agreement with ImmunoTek GH, LLC (ImmunoTek) for the opening and management of 28 plasma collection centers. The transaction was instrumentalized through the creation of Biotek America LLC ("ITK JV"), which created a series of shares for each site (silos). Grifols holds 75% of each series of shares and ImmunoTek the remaining 25%. Approximately 3 years after the opening of each center, Grifols acquires the center. Grifols made advances of up to US Dollar 5,000 thousand for each center to ImmunoTek, totaling US Dollar 140,000 thousand (Euros 126,697 thousand) for the 28 centers, which will be deducted from their purchase price of the last 14 centers. Although Grifols holds a 75% interest in the ITK JV, this interest is considered a "joint operating company" because under the agreements between the parties, Grifols exercises joint control until the acquisition of the centres. Likewise, to the extent that Grifols anticipates the funds and the silos are created to sell all plasma production to Grifols, the assets and liabilities of the ITK JV and its series are integrated at 100%, with the corresponding eliminations for the transactions with the ITK JV and its silos. Full details of the transaction are set out in note 10 of the consolidated annual accounts for the year ended December 31, 2023. The amounts payable for the donor centers acquisition net of deposits and on the basis of a minimum production and existence of the centres at the time of purchase, would be the following amounts according to the estimated payment schedule: Thousand US Dollar Euros 2024 130,956 119,051 2025 77,928 70,844 2026 61,910 56,282 Total 270,794 246,177 Finally, each individual silo is a business and a joint arrangement. Also, as Grifols acquires the sites, a step acquisition will not arise and therefore the difference between the consideration paid for each site and the fair value of the assets and liabilities, which will not differ significantly from their carrying amount, will be recognized as goodwill (see note 3).

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Condensed Consolidated Interim Financial Statements for the six-month period ended 30 June 2024 18 The assets and liabilities assigned to the aforementioned joint operation at June 30, 2024 are as follows: Net assets Thousand of Euros Other intangible assets 59,196 Property, plant and equipment 22,114 Non current financial assets 35 Inventories 16,151 Trade and other receivables 27,147 Other current assets 1,042 Cash and cash equivalents 19,938 Total assets 145,623 Non current liabilities (87,065) Current liabilities (90,442) Total liabilities (177,507) Total equity (31,884) (10) Financial Assets The composition of non-current financial assets in the consolidated balance sheet at June 30, 2024 and December 31, 2023 is as follows: In Non-current guarantee deposits, there are long-term deposits with related parties that amount Euros 943 thousand at June 30, 2024 (Euros 943 thousand at December 31, 2023) (see note 22). The remaining 6.58% interest in SRAAS shares is included under the caption “other non-current investments”. This investment has been considered a financial asset measured at fair value with changes in ‘Other Comprehensive Income of financial asset at fair value’ whose fair value at June 30, 2024 has been calculated on the basis of the SRAAS share price at that date in the amount of Euros 440,173 thousand (see note 11) recognizing a gain under the heading of other comprehensive income of Euros 4.268 thousand net of tax.

Those balances have been reclassified from non-current to current based on their maturity. In note 22 it is disclosed the transactions with associated and related parties. (b) Non-current and current loans Details of non-current and current loans are as follows: 30/06/2024 31/12/2023 Credits to related parties 123,285 115,209 Credits to third parties 20,803 21,537 Total non-current and current credits 144,088 136,746 Thousands of Euros "Credits to related parties" corresponds to a loan signed by Scranton Enterprises, BV. with the Group on December 28, 2018 for an initial amount of US Dollar 95,000 thousand (Euros 86,969 thousand) related to the payment of the sale of the shares in BPC Plasma, Inc. and Haema, AG. As of June 30, 2024, the heading includes an additional amount of Euros 15 million drawn down during the 2023 financial year under the same conditions as the initial loan, as well as accrued and unsettled interest to date. (11) Non-current assets held for sale On December 29, 2023, Grifols reached an agreement with Haier Group Corporation for the sale of a 20% equity interest in Shanghai RAAS (SRAAS) for RMB 12,500 million. Pursuant to IFRS 5, such stake subject to the sale transaction was considered as a “Non-current asset held for sale” in the consolidated statement of financial position as at December 31, 2023 in the amount of Euro 1,089,856 thousand.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Condensed Consolidated Interim Financial Statements for the six-month period ended 30 June 2024 20 On June 18, 2024, after obtaining the corresponding authorisations from the required regulatory authorities and after the fulfilment of certain agreed conditions, the sale transaction was closed for RMB 12,500 million (Euro 1,607,500 thousand at the exchange rate at the date of the transaction). On June 28, 2024, the proceeds from the sale, net of transaction costs and taxes paid in China, amounted to Euros 1,564,256 thousand at the exchange rate at that date, and were credited to Grifols' RMB bank account (see note 13). In order to reduce exposure to changes in the EUR/ RMB exchange rate and guarantee the amount collected in Euros, Grifols has contracted a EUR/ RMB forward rate financial instrument (Fx Foward). These funds have been used to reduce debt (see note 15). As a result of this sale transaction, Grifols loses its significant influence over its interest in SRAAS at the closing of the transaction. The remaining 6.58% stake in SRAAS shares is considered a financial asset valued at fair value with changes in "Other comprehensive income" which fair value at the date of the transaction has been calculated on the basis of the listed price of the SRAAS share at that date in the amount of Euros 434,481 thousand (see note 10). Grifols also lost its indirect 11.79% stake in GDS which was held through its shareholding in SRAAS, resulting in an increase of Euros 507,803 thousand in equity attributable to minority interests. In addition, as part of the transaction, a series of agreements were signed (see note 20.e), including the extension of the exclusive distribution agreement for albumin, which will mean considerable growth in sales in China for Grifols in the coming years. This transaction has not had a material impact on the condensed consolidated income statement for 2024 and is calculated as follows: Selling price 1,607,500 Fair value of SRAAS 6,58% 434,481 Minus: book value of the Non-current asset held for sale and transaction costs (1,123,588) Minus: book value of the Investment accounted for using the equity method as of the date of loss of the significant influence (367,700) Minus: increase of the minority interest of GDS (507,803) Other contractual obligations (see Note 20.e) (10,433) Result before the reclassification of translation differences 32,457 Accumulated translation differences in equity 1,633 Transaction result: profit 34,090 Taxes on profits in China and Spain (34,544) Result net of taxes (454) Thousands of euros The result of the transaction includes an unrealized gain corresponding to the revaluation of the investment retained by Grifols in SRAAS at fair value in the amount of Euros 68,414 thousand. (12) Trade and Other Receivables At June 30, 2024 and during 2023, Grifols has sold receivables without recourse to some financial institutions (factors), to which substantially all the risks and rewards of ownership of the assigned receivables are transferred. Control over the assigned receivables, 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 contractual terms include early collection of the assigned receivables ranging from 65% to 100% of the nominal amount and a coverage limit that the factors would cover in case of insolvency of the debtors, ranging from 90% to 100% of the transferred nominal amount.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Condensed Consolidated Interim Financial Statements for the six-month period ended 30 June 2024 21 These contracts have been considered as non-recourse factoring and the amount advanced for the factors has been derecognized from the balance sheet. In addition, in 2024 and 2023, some receivables assignment contracts were signed with a financial institution, in which Grifols retains the risks and rewards inherent to the ownership of the assigned receivables. These contracts have been treated as factoring with recourse, where the amount assigned is retained on the consolidated balance sheet and a short-term debt has been recognized for an amount equal to the consideration received from the factor for the assignment.

The Group's consolidated effective tax rate is 27%, excluding the effect of Biotest, for the six-month period ended June 30, 2024 and 25% for the six-month period ended June 30, 2023. 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. The resulting assessments were signed in conformity by the Group on 8 November 2021. 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, S.A. AND SUBSIDIARIES Notes to the Condensed Consolidated Interim Financial Statements for the six-month period ended 30 June 2024 29 • 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. There have been no relevant developments with respect to this audit during the six-month period ending June 30, 2024. • 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 June 2018 to December 2019. The audit procedure is not over, although the group has signed in disagreement the corresponding provisional assessment proposals. 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. It should be noted that the Inspection has stated that it considers there have been no infringements in any of the taxes subject to verification. The Group acts with the tax authorities in a cooperative and transparent manner to resolve disputes and considers that its position in the years and matters described above have been in accordance with the law and are based on a reasonable interpretation of the applicable regulations. Therefore, the Group intends to submit pleadings to the Tax Authorities in this regard. Should the Tax Authorities not reconsider the position, the Group also intends to file the appropriate appeals and petitions to best defend its interests against the settlements finally issued. As of June 30, 2024, the Group has recorded an amount of Euros 92,517 thousand as a provision for previous disputes and pending tax litigation (such provision amounted to Euros 76,604 thousand as of December 31, 2023). According to the information currently available, the Group and the tax advisors consider that the provisions that have been recorded are adequate based on the existing risk best estimate and reasonably cover the possible obligations derived from current audits and litigations with regard to taxes. Minimum taxation (Pillar2 OECD) As at June 30, 2024, 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 January 1, 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 most of the territories in which it operates and expects to benefit from the "transitional safe harbour" which allows avoiding the additional tax 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. However, the Group does not expect a significant impact from Pillar 2 legislation arising from its operations in Ireland or in any of the other jurisdictions, although the complexity of the legislation could, in specific cases, give rise to additional taxation, which is not expected to be material. (19) Discontinued Operations During the six-month period ended June 30, 2024, and June 30, 2023, the Group has not discontinued any operations. (20) Commitments and Contingencies (a) Guarantees The Group has no significant guarantees extended to third parties.

In addition, Grifols, S.A. acts as guarantor of the commitments made for the purchase of the plasma centers (note 3 and 9). Additionally, the Group has significant guarantees committed to third parties as described in note 15. (c) Obligations with personnel The Group’s annual contribution to defined contribution pension plans of Spanish Group companies for the six-month ended in June 30, 2024 has amounted to Euros 564 thousand (Euros 534 thousand for 2023). In the event that control is taken of the Company, the Group has agreements with 34 employees/directors whereby they can unilaterally rescind their employment contracts with the Company and are entitled to termination benefits ranging from two to five years’ salary. In addition, the share-based remuneration plans maintained by the Company for certain employees include clauses according to which, in the event of a change of control, the amounts pending exchange would be early settled under the terms described in said agreements. The Group has contracts with 22 executives entitling them to termination benefits ranging from eleven months to four years of their salary in different circumstances. Restricted Share Unit Retention Plan In March 2022, the Group established a Restricted Stock Share Plan (hereinafter RSU) for certain employees. Under this plan, an employee may elect to receive up to 50% of his or her annual bonus in Class B non-voting ordinary shares (Grifols Class B Shares) or Grifols American Depositary Shares (Grifols ADSs), and the Group will match this with an additional 50% contribution in RSUs. Class B Grifols shares and Grifols ADSs are valued at the date of grant of the bonus. These RSUs will have a vesting period of 2 years and 1 day and will subsequently be exchanged for Grifols Class B Shares or Grifols ADSs (American Depositary Shares representing 1 Class B Share). If an eligible employee leaves the company or is terminated prior to the vesting period, he/she will not be entitled to the additional RSUs. At June 30, 2024 the Group has settled the 2022 RSU plan for an amount of Euros 5,900 thousand (Euros 3,296 thousand at December 31, 2023 corresponding to the 2020 RSU plan).

Settlement date Number of RSUs assigned Unit fair value (Euros) 2025 274,500 8.52 2027 274,500 6.92 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 18,6 million in the six-months period ended 30 June 2024 (US Dollars 18,3 million in the six-months ended 30 June 2023). 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.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Condensed Consolidated Interim Financial Statements for the six-month period ended 30 June 2024 32 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 AG On December 28, 2018, the Group sold BPC Plasma Inc. and Haema AG to Scranton Enterprises B.V. The sales contract included a purchase option for Grifols that grants it the irrevocable and exclusive right (not an obligation) to acquire the shares sold to Scranton Enterprises B.V. (both at the same time) at any time from the effective date of sale. In relation to the purchase option and given that it is based on a variable number of shares and a variable acquisition price, said instrument is a derivative financial instrument that must be valued at fair value with changes in the profit and loss account. The exercise price of the option will be equal to the greater of: (i) the same price at which the shares were sold to Scranton, adding the expenses related to the transaction and the increase in net working capital from the time of exercise of the option and the time at which the sale occurred, and (ii) the amount necessary to cancel the debt contracted by Scranton with the financing entity of the transaction for an amount of US Dollars 360 million, plus accrued interest, as well as any other amount necessary to cancel said debt. Based on the contractual conditions, Grifols has estimated the price of the option as (i) the price for which the shares have been sold to Scranton (US Dollars 538,000,000) plus (ii) the variation in working capital, which, given the business model of both companies, will be mainly represented by undistributed profits. Insofar as the exercise price has been established for a value similar to the fair value of BPC and Haema, the option does not have a significant value. On the other hand, since the valuation of the option is based on non-observable market variables, it corresponds to Level 3 of the fair value hierarchy. Considering the uncertainties underlying the valuation of the option as it deals with non-observable variables, and the value of the same not being significant, said value has not been recognized as of 30 June 2024 and 31 December 2023. Likewise, both the shares of Haema AG and the shares of BPC Plasma Inc. are currently pledged as collateral for the loan from Scranton Plasma BV with Bank of America. If a default occurs under the loan agreement, as long as the financing banks have not executed the corresponding pledge, Grifols may exercise the purchase option. Grifols will pay the bank in preference to Scranton Plasma BV until the amount of the debt at the time of acquisition is settled. There is no time limitation in the loan agreement for Grifols to exercise the repurchase option. As of June 30, 2024, there have been no default events. Purchase option on Haema PlasmaKft. On 1 February 2021 the Group signed a call option on the shares of Haema Plasma kft, exercisable by the Group only 12 months after signing and with an expiry of 48 months from the date on which the option becomes exercisable. The option price was set at thirteen times EBITDA minus net debt. Grifols did not make any monetary consideration for the purchase option agreement when signing the agreement. 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

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Condensed Consolidated Interim Financial Statements for the six-month period ended 30 June 2024 33 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 July 29, 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. As of 30 June 2024, no amount has been recognized for these options as they are not significant. Canadian Blood Services In September 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 made the following commitments for the acquisition of plasma and self-built centers in Canada: Thousand of Euros 2024 2025 2026 2027 16,747 21,386 31,328 17,844 (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 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 has been considered at the closing of the sale transaction. This commitment will be 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 best 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 creditor, and Grifols, as debtor.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Condensed Consolidated Interim Financial Statements for the six-month period ended 30 June 2024 34 • Grifols retains the right to appoint one 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 the event that Grifols wishes to sell these shares. The voting proxy agreement has been valued at Euros 10 million. (f) Judicial procedures and arbitration • ABBOTT LABORATORIES v. GRIFOLS DIAGNOSTIC SOLUTIONS INC., GRIFOLS WORLDWIDE OPERATIONS LIMITED AND NOVARTIS VACCINES AND DIAGNOSTICS, INC. Served: October 8, 2019 US District Court, Northern District of Illinois Patent Infringement, Civil Action No. 1:19-cv-6587 Abbott Laboratories (“Abbott”), GDS, GWWO and Novartis Vaccines and Diagnostics, Inc. are in dispute over unpaid royalties payable by Abbott to GDS and Ortho-Clinical Diagnostics (“Ortho”) under an HIV License and Option agreement dated August 16, 2019 (the “HIV License”). On September 12, 2019, GDS and Ortho filed Notice of Arbitration. On October 3, 2019, Abbott terminated the HIV License and filed for Declaratory Relief seeking to invalidate the licensed patent. On March 16, 2020, Grifols and Ortho filed an answer and counterclaim to the litigation, while simultaneously pursuing arbitration for the pre-termination amount owed by Abbott. The arbitration hearing was June 15-16 , 2020. Grifols/Ortho were awarded $4 Million. NEXT ACTION: Expert Discovery was concluded on October 14th 2022 and the parties filed dispositive motions, including a motion for summary judgement by Abbott, which was unsuccessful to dispose of the litigation. GDS and Ortho contend that the patent is valid and they believe that Abbott will be unsuccessful in its Declaratory Relief action. A mediation took place on 31 January 2024 without success. Further pre-trial hearings will be held between now and trial setting. Trial is expected to be in late 2024 or early 2025. • RAMIREZ-VIVAR, ALFONSO v. GRIFOLS DIAGNOSTIC SOLUTIONS, INC.

The settlement amount includes a release for any wage and hour claims, claims under the Private Attorneys' General Act, and attorneys' fees. The Court approved the settlement in a hearing that occurred on July 18, 2024. The settlement proceeds will be due sometime in the next sixty (60) days, and the checks would be distributed to class members within month thereafter. The Court scheduled a final compliance hearing for March 27, 2025, to ensure that all class requirements have been met. Plaintiff’s counsel will file a final report and declaration prior to the hearing, in which case no appearance will be necessary. CLASS POTENTIAL: Approx. 300 CA GDS employees for payroll/wage & hour violations per pay period for 5 years.

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Condensed Consolidated Interim Financial Statements for the six-month period ended 30 June 2024 35 • CERUS CORPORATION v. LABORATORIOS GRIFOLS, S.A. Cerus Corporation ("Cerus") and Laboratorios Grifols, S.A. ("Grifols") entered into a Manufacturing and Supply Agreement executed in 2016, pursuant to which Grifols was to manufacture and supply to Cerus processing and filters sets to be used by Cerus in its own product (the "Agreement"). As a result of Grifols' decision to discontinue the manufacturing, sale and support of its blood bag product business worldwide, Grifols was unable to comply with the Agreement. In December 2021, Cerus filed a notice of arbitration in the UK pursuant to the terms of the Agreement alleging wrongful termination of the Agreement by Grifols. Furthermore, in January 2022, Cerus filed injunctive measures with the Courts of Rubí (Barcelona) requiring the suspension of the closure of Grifols' blood bags production facility until the arbitration proceedings is finalized. NEXT ACTION: In March 2024, the Parties agreed to further suspend the proceedings, which was granted by the Tribunal until June 7, 2024. However, the Tribunal had called the parties to a short remote hearing on May 30, 2024 in order to avoid that this matter drifted indefinitely. Further, at the end of March, 2024, the Spanish court made an order withdrawing the claim, and thereby discontinuing the Spanish proceedings, which is now closed and each party is to cover its own costs. In respect of the arbitration and before May 30, 2024, the parties engaged in negotiations to find an agreement on, either settling the claim pending in arbitration or defining the terms on how the arbitration should proceed forward. To this extent, the parties requested to the Tribunal to suspend the May hearing, which the Tribunal agreed to do until the next available date as of July 2024. In the meantime, while the companies' respective counsels are negotiating a settlement of the arbitration, the commercial and technical teams are working on the manufacturing and supply activities within the terms of the Agreement.

In addition, as detailed in note 29(c) to the consolidated annual accounts for the year ended December 31, 2023, certain Company directors and key management personnel have termination benefit commitments. (23) Subsequent events Description of Certain Inside Information: Potential Transaction On 8 July 2024, the Parent Company (by means of a communication to the market of Inside Information) informed that on 7 July 2024 an extraordinary meeting of the Board of Directors had been held to analyse the request of certain family shareholders of Grifols and Brookfield Capital Partners (UK) Limited ("Brookfield") for access to certain Group information, in order to carry out a due diligence process in relation to a possible acquisition of shares of Grifols, S.A.. Specifically, in accordance with the Inside Information note communicated by Brookfield to the market on 8 July 2024, various companies that hold the shares of the aforementioned family shareholders (Deria S.A., Ponder Trade S.L. and Ralledor Holding Spain, S.L. together with Scranton Enterprises BV) (the "Family Shareholders") and Brookfield entered into an exclusivity arrangement to evaluate the potential joint tender offer transaction for the entire share capital of Grifols (class A shares and class B shares), and the delisting of the Group from the Spanish Stock Exchanges and NASDAQ (the "Potential Transaction"). As of today, there is no agreement regarding the potential terms or conditions of the Potential Transaction. At this stage, there is no guarantee that Brookfield and/or the Family Shareholders will make a tender offer for the shares of the Parent Company and/or that a delisting of the shares of the Parent Company will be proposed or agreed. (A) Certain Contractual Implications in a take of control (toma de control) The financing contracts entered into by the Parent Company, as well as the Corporate Bonds issued described in Note 15, include clauses whereby the potential creditors in the different instruments could early terminate such contracts in the event of a take of control of the Parent Company, provided that, in accordance with the terms and conditions under which the Potential Transaction finally materialises, the terms defined as a take of control in such contracts apply. In addition, as described in Note 20 c), the Group has entered into agreements with executives and directors whereby they may unilaterally terminate their employment contracts with the Parent Company and are entitled to certain indemnification in the event of a take of control of the Parent Company, provided that, in accordance with the terms and conditions under which the Potential Transaction finally materialises, the terms in such contracts apply. Similarly, the share-based remuneration plans maintained by the Parent Company for certain employees include clauses according to which, in the event of a take of control - provided that, in accordance with the terms and conditions under which the Potential Transaction finally materialises, the terms defined as a take of control in such contracts apply -, the amounts pending exchange would be early settled. In addition, certain operating contracts entered into by the Group with third parties also include clauses providing for a potential early termination in favour of the counterparty in the event of a take of control of the Parent Company provided that, in accordance with the terms and conditions under which the Potential Transaction finally materialises, the terms defined as a take of control in such contracts apply. At the date of preparation of the condensed interim consolidated financial statements at 30 June 2024, insofar as no public tender offer for the shares of Grifols, S.A. has yet been made and the terms and conditions under which the Potential Transaction would be reflected are not known, no situation exists whereby any of the early termination clauses mentioned in the preceding paragraphs would apply, and the terms and conditions under which the Potential Transaction would be reflected are not known, so there is no situation in which any of the early termination clauses mentioned in the preceding paragraphs would apply, and therefore the Group would not incur in any obligation to early repay its financing, nor would any counterparty have the right to early terminate any of these operating contracts, nor would there be any indemnification payments or settlement of obligations with its executives and employees. In any event, the Directors of the Parent Company understand that, in the event that the Potential Transaction constitutes or results in a take of control that could trigger the early termination of the aforementioned contracts

GRIFOLS, S.A. AND SUBSIDIARIES Notes to the Condensed Consolidated Interim Financial Statements for the six-month period ended 30 June 2024 43 or, as the case may be, payment obligations or settlements to its officers and employees, the submission of any potential takeover bid by the potential bidder shall be subject to the condition that, as a result thereof, the financial and economic viability of the Group would not be compromised. (B) Certain Statutory Implications As described in Note 14, the Parent Company's share capital consists of Class A Shares and Class B Shares, Class B Shares being non-voting shares with preferential economic rights according to its Articles of Association. Treatment of Class A and Class B shares in the event of a public offer for the acquisition of shares Section 4.1. of article 6.Bis of the Articles of Association of the Parent Company provides that in the event that a public offer is made and settled for the acquisition of all or part of the shares of the Parent Company, the holders of Class B Shares shall be entitled to participate in such offer and to have their shares acquired in the same manner and on the same terms as the Class A Shares (including, without limitation, for the same consideration). Otherwise, the holders of the Class B Shares are entitled to require the Parent to redeem their shares (in accordance with the terms and process set out in Articles 4.2 and 4.3 of the Articles of Association). The wording of section 4.1 of article 6 bis of the Articles of Association of the Parent Company is transcribed literally below: [...] 4. Right of redemption 4.1 Redemption event. Each Class B Share entitles its holder to obtain its redemption as set forth in this section 4 in the event that (each offer that meets the following requirements, a “Redemption Event”) a tender acquisition offer over all or part of the shares in the Company is made and settled (in whole or in part), except if holders of Class B Shares have been entitled to participate in such offer and to their shares acquired in such offer equally and on the same terms as holders of Class A Shares (including, without limitation, for the same consideration). Approval of Exclusion Resolution In addition, certain extraordinary matters defined pursuant to article 6.2 of the Articles of Association, including any resolution approving the delisting of any shares of the Parent Company from trading on any stock exchange or secondary market, must be approved by a simple majority of the Class B Shares then outstanding. The Board of Directors of the Parent Company will at all times ensure compliance with the Articles of Association and act in the best interests of the Company and in the best interests of its shareholders, employees and other stakeholders. Acquisition of plasma centers As a result of the collaboration agreement entered to ImmunoTek GH, LLC in 2021, the Group acquired 7 plasma centers, through its 100% subsidiary Grifols Bio North America, LLC, for an amount of US Dollar 131 million. Settlement derived from hedging On July 5, 2024, Grifols settled the EUR/RMB exchange rate hedging derivative (see note 11) receiving an amount of Euros 1,559,942 thousand. This transaction has not had a significant impact on the consolidated income statement.

GRIFOLS, S.A. AND SUBSIDIARIES Consolidated Management Report for the six-month period ended June 30, 2024 (Free translation from the original in Spanish. In the event of discrepancy, the Spanish language version will prevail) 1 Management Report for the six-month period ended June 30, 2024, should be read in conjunction with the corresponding consolidated interim financial statements and related notes. The comments and analysis included in the report may contain projections and forward-looking considerations that involve risks and uncertainties. Please refer to the legal notice included at the end of the document. In a half-year marked by an acceleration in operational and financial performance, Grifols reported solid results for the first six months of 2024 that reaffirmed its guidance for the year. Led by a strengthened leadership team, the company continues to make progress in achieving its strategic objectives, with a focus on cash generation, debt reduction, deleveraging, operational excellence and value creation for all its stakeholders. In this regard, the strategic alliance with the Haier Group in China involving the sale of a 20% stake in Shanghai RAAS (SRAAS), completed on June 18, 2024, as well as the execution of the cash generation plan, support both the debt reduction path and the efforts to improve cash flow, respectively. EVOLUTION OF REVENUES In this context, Grifols' revenue reached €3,444 million in the first half of 2024, representing an increase of +7.5% cc1 (+6.8% reported2 ). It is worth highlighting the solid revenue growth of +9.3% cc (+7.8% reported) in the second quarter of the year to 1,818 million euros, driven by the growth of the main business units: Biopharma, Diagnostic and Bio Supplies. Biopharma Biopharma's revenues increased by +8.9% cc (+8.3% reported) to €2,922 million in the first half of the year and by +8.4% cc (+8.5%) to €1,528 million in the second quarter. Framed on solid business fundamentals, the main growth drivers have been strong underlying demand for key plasma proteins, a solid plasma supply and a favorable pricing and product mix combination. Of particular note was the performance of immunoglobulin sales, the company's main franchise, up +13.1% cc in the half year due to higher growth in subcutaneous immunoglobulin (SCIG) Xembify® (+58.9% cc). Grifols continues to strengthen the immunoglobulin franchise with a strategy focused on primary immunodeficiencies (PI) and secondary immunodeficiencies (SID), the indications with the greatest growth potential in the coming years, while maintaining leadership in neurology and intensive care. The company's focus is on continuing to drive growth in the U.S. and prioritizing certain countries, while accelerating the expansion and penetration of Xembify®, its subcutaneous formulation. Sales of albumin grew by +9.6% cc in the first half of 2024, driven mainly by demand in China and the United States. In addition, Grifols' commercial innovation within the framework of the strategic alliance with Haier 1 Operating or constant exchange rate (cc) excludes exchange rate variations for the period 2 Reported includes the impact of foreign exchange rates

In the event of discrepancy, the Spanish language version will prevail) 2 allows us to continue to expand supply in the country. In addition, the addition of Alfa-1 and other specialized proteins has remained stable. Diagnostic Diagnostic posted revenues of €323 million, up -3.7% cc year-on-year (-5.5% reported), driven by €164 million in the second quarter, representing growth of +1.2% cc (-0.5%). Excluding the €19 million commercial one-off that took place in Q1 2023, the division posted a +1.9% cc increase in the half-year. The positive performance of the main growth driver, blood typing solutions (+14.9% cc in the first half of the year) in the main regions was particularly noteworthy. Bio Supplies Bio Supplies grew +32.6% cc (+32.6% reported) to €110 million in the first half, up +92.6% cc (+93.5%) and €78 million in revenues in the second quarter thanks to sales phasing that impacted the first quarter and was offset during this quarter, as planned. The division continues to benefit from the integration of Access Biologicals. PLASMA SUPPLY AND COST PER LITER Grifols continues to increase plasma supply and effectively manage its cost per liter (CPL), driving further margin expansion. Plasma supply continues to grow sustainably, and CPL has stabilized in the second quarter compared to the first quarter of 2024, having been reduced by nearly 25% from the peak reached in July 2022. The outlook for plasma is positive, highlighting the opportunity for cost reductions related to increased efficiencies, streamlined operations and progress in technology and digitization. FINANCIAL RESULTS AND DELEVERAGING In the first six months of 2024, reported gross margin rose to 37.8% of revenue, improving from 36.0% in the same period last year, driven primarily by lower CPL and product mix. Taking into account the approximately nine-month inventory accounting lag that applies in the plasma industry, this improvement in CPL will continue to lead to incremental margin expansion in the second half of 2024. Reported EBITDA amounted to €723.6 million in the first half and €413.6 million in the second quarter, representing margins on revenues of 21.0% and 22.8%, respectively. At the same time, adjusted EBITDA amounted to €791.2 million in the first half, representing a margin of 23.0% on revenues, and €440.8 million in the second quarter, with a 24.2% margin – mainly including €44 million of non-recurring transaction and restructuring costs and €22 million from the Biotest Next Level (BNL) project.

GRIFOLS, S.A. AND SUBSIDIARIES Consolidated Management Report for the six-month period ended June 30, 2024 (Free translation from the original in Spanish. In the event of discrepancy, the Spanish language version will prevail) 3 The sequential improvement was supported by Biopharma's performance-led growth, cost savings from the operational improvement plan and higher absorption of fixed costs. The financial result (loss) amounted to €389.1 million in the first half of the year (€274.1 million in 2023), mainly impacted by larger deferred financial expenses from our debt reducing by €1.6bn with the SRAAS proceeds. Reported net income of the Group amounted to EUR 36.3 million in the first half of 2024. Grifols reiterates its commitment to debt reduction. Its leverage ratio stood at 5.5x in the first half of 2024, driven by the 1.6 billion euros proceeds from the sale of 20% of SRAAS and the organic improvement in EBITDA. The target is to bring the ratio to 4.5x by the end of 2024, with the main lever being EBITDA improvement and, to a lesser extent, cash generation. The proceeds from the SRAAS transaction will be allocated in full, and on a pro rata basis, to reduce the 2025 Senior Secured Notes (SSNs) and the 2027 Term Loan B (TLB), according to the Credit Agreement. In addition, the €1 billion Private Placement Note (PPN) has already been used to repay the 2025 Senior Unsecured Notes (SUNs). The Company does not have additional maturities until 2027. Excluding the impact of IFRS 163 3, Grifols' net financial debt amounted to 8,262.1 million euros. At June 30, 2024 and excluding the net proceeds from the divestment of SRAAS, Grifols had a liquidity position of 915 million euros, which includes a cash position of 568 million euros. CORPORATE GOVERNANCE Changes in governance separating property management within the framework of a planned strategy In February, Raimon Grifols and Víctor Grifols Deu decided to put an end to their executive role, remaining on the Board of Directors of Grifols as proprietary directors. As of May 31, 2024, they cease to have the category of "executive directors" as they cease to perform management functions at Grifols, and as of June 1, 2024, they become "proprietary directors". These changes are part of a long-planned and carefully designed strategy for the evolution of Grifols' corporate governance, which Raimon Grifols and Víctor Grifols Deu initiated in 2022, together with the Board, to progressively separate ownership from management of the company, setting a new standard for family-owned companies listed on the Spanish stock exchange. Nacho Abia takes over as Chief Executive Officer On April 1, Nacho Abia officially assumed the position of Chief Executive Officer of Grifols, reporting directly to Thomas Glanzmann, who will retain the position of Executive Chairman. Previously, on February 26, 2024, 3 3 As of June 2024, the impact of IRFS 16 on total debt is €1,134.2 million

GRIFOLS, S.A. AND SUBSIDIARIES Consolidated Management Report for the six-month period ended June 30, 2024 (Free translation from the original in Spanish. In the event of discrepancy, the Spanish language version will prevail) 4 Nacho Abia was appointed to the Board of Directors of Grifols. Consequently, Raimon Grifols and Víctor Grifols Deu transfer their responsibilities to Nacho Abia and will remain with the company as advisors in a transition period that ended on May 31, 2024. The addition of Nacho Abia concludes a planned corporate governance evolution that began in 2022 to separate ownership from management of the company. Nacho Abia will focus on continuing to accelerate the company's growth, drive operational excellence and execute the deleveraging plan. He will also continue to reduce operational complexity and improve clarity. AGREEMENTS Grifols Egypt moves towards self-sufficiency thanks to solid plasma volumes obtained In February, Grifols announced that its integrated plasma collection and blood product production platform in Africa is making great strides towards its goal of achieving local self-sufficiency in these essential treatments. Grifols Egypt, which expects to double plasma collections by 2024, is already receiving enough donations to cover Egypt's current domestic need for immunoglobulins. Meanwhile, the project to build a new 105,000 square meter, state-of-the-art production center in the Medical City of the New Administrative Capital, which will include fractionation and purification plants, logistics facilities and what will be Grifols' first fully automated plasma testing laboratory in the world, is still underway. When fully operational, Grifols Egypt will analyze more than one million plasma samples per year. Grifols completes the sale of 20% of its stake in Shanghai RAAS and forges a strategic alliance with Haier Group in China On June 18, 2024, Grifols reported the sale of its 20% stake in SRAAS for approximately 1.6 billion euros and the establishment of a strategic alliance with Haier Group Corporation (Haier Group), following confirmatory due diligence by Haier and after obtaining all required government approvals. Grifols and Haier Group will collaborate through SRAAS to create synergies that will help boost the development of the Chinese healthcare system. The two companies extend their exclusive albumin distribution agreement for the next 10 years, with guaranteed minimum supply volumes for the next five years (2024-2028). SRAAS will be able to extend this agreement until 2044. The demand for albumin in China is significant and is expected to grow considerably in the coming years. With this transaction, announced in December 2023, Grifols maintains its presence in China and its commercial agreements with SRAAS, while meeting its deleveraging commitment. The company will use all proceeds to meet its deleveraging commitment.

To this end, we have continued with our nutrition activities in Spain, and have launched the sleep campaign, with various activities in the countries where we operate, such as masterclasses by experts in sleep hygiene. In the second half of the year, we will work on tobacco consumption as the last cardiovascular risk factor. From 2023, Grifols also has a new corporate mental health policy to support and safeguard the well-being of its human team in a comprehensive manner. In this context, in 2023 Grifols implemented a specific mental health action plan, where one of the actions launched was to monitor various indicators of mental health and well-being of the workforce, provide them with tools to prevent and manage anxiety and stress, and foster a culture that prevents any type of discrimination related to mental health. During 2024, work has been carried out on an emotional health survey. In this regard, the information from the company's global engagement questionnaire is used to extract an emotional management indicator that considers three factors: leadership, organization and personnel.

GRIFOLS, S.A. AND SUBSIDIARIES Consolidated Management Report for the six-month period ended June 30, 2024 (Free translation from the original in Spanish. In the event of discrepancy, the Spanish language version will prevail) 10 Transparency As part of its commitment to transparency, Grifols has detailed for the ninth consecutive year all payments and other transfers of value related to medicines and healthcare technology made to professionals and organizations in the sector in various European countries defined in the EFPIA scope, including Spain. In 2023, Grifols made transfers of value in Europe for a total amount of 14.5 million euros, which represents a decrease of 25% compared to 2022. Of these, 68.9% were transfers of value related to R&D, amounting to 10.0 million euros. Transfers of value to healthcare organizations and professionals amounted to €4.5 million. In addition to Europe, Grifols applies this transparency policy in the United States as stipulated by the Centers for Medicare & Medicaid Services (CMS). Social action Grifols extended its commitment to the World Federation of Hemophilia's (WFH) humanitarian aid program until 2030 and will donate a minimum of 240 million international units (IU) of clotting factors (factor VIII and factor IX) to the WFH Humanitarian Aid Program in the period 2022 - 2030. Grifols has been collaborating with the World Federation of Hemophilia since 2014 and, in addition to support of humanitarian initiatives, we have also supported and encouraged patient-centric initiatives through the Grifols Hemophilia Awareness Global Awards (GHAGA) which has provided winners awards of up to €30,000 for programs that have contributed to improving the care of hemophilia patients and their quality of life. Grifols also collaborates with Habitat for Humanity since 2014 to provide safe, decent and healthy housing in communities in across the United States. Employees in California have helped the organization meet the need for affordable housing and supported local non-profit organizations by rehabilitating homes for families and building playhouses in their nearby communities, respectively. Nearly 50 Grifols volunteers from our sites in San Diego, Los Angeles and Emeryville participated in six Habitat build events during the first half of the year. RISKS At June 30, 2024, the Group maintains the same financial risk management policies and objectives than it had at December 31, 2023. In this context, the Group has actively worked to implement its deleveraging plan by taking the following actions: On April 23, 2024, a private placement of Euros 1,000 million of senior secured bonds was made and, on June 4, 2024, an additional placement of Euros 300 million of senior secured bonds. The funds received have been used for the redemption of senior unsecured notes maturing in May 2025 and the remainder was used for the repayment of the revolving facility (RCF). On June 18, 2024, the sale of the 20% shareholding in Shanghai RAAS to Haier was completed and these funds will be used to partially amortize the senior secured debt on a pro rata basis.

In the event of discrepancy, the Spanish language version will prevail) 12 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 comple(ment 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.

More accurately reflects the company's organic performance, including or excluding certain non-recurring amounts, see detail below: - Restructuring costs: in 2022, 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. Specifically in the year 2022, costs of €36.1 million were incurred, mainly related to the closure of 18 plasma centers with the aim of optimizing the plasma center network. Additionally, in 2023, a restructuring impact related to this Operational Improvement Plan is recorded, totaling €159.3 million. In the first half of 2024, this amounted to €12m. - Transaction costs: during the COVID-19 period, the company

In this sense, Grifols acquires Biotest in September 2021 and closes the acquisition in April 2022. The objective of this transaction is based on acquiring two new key proteins for its portfolio that will contribute to improving profitability and plasma liter revenues. In addition to enhancing its economic performance, this transaction will contribute to expanding and diversifying Grifols' plasma supply; it will strengthen its operations and revenues in Europe, the Middle East, and Africa. In 2023, 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 €31m. -Diagnostic commercial true-up: excludes the extraordinary impact related to revenue recognized as a result of winning a litigation with a customer in the Diagnostics business unit in the first half of 2023. -Impairments: in 2023 it refers to an impairment in “Others” business unit. Divestment gain: Negative adjustment to EBITDA following the divestment of MedKeeper in 2022. This impact (negative adjustment) has been excluded in the third quarter of 2023 as it is considered non-recurring, linked to an extraordinary

The reason for the transaction is that this company was not linked to Grifols' core operations. -Biotest Next Level (BNL) project: in 2023, this refers to a specific project aimed at increasing Biotest's production capacity in Dreieich, Germany. 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: in H1’24, most of these one-offs were related to costs as a consequence of the short-seller attack.
