Key Audit Matters Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the financial statements of the current period. These matters were addressed in the context of our audit of the financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters. Description As indicated in Note 13 to the accompanying financial statements, the Company has ownership interests in the share capital of Group companies and associates with a carrying amount of EUR 3,971 million at 31 December 2023. Each year the Company assesses whether there is any objective evidence of impairment of those ownership interests in Group companies and associates. For the investments for which there are indications of impairment, the Company estimates their recoverable amount on the basis of impairment tests prepared using discounted cash flow-based valuation techniques, in which it employs projections aligned with estimated earnings, investments in non-current assets and investments in working capital, as well as other assumptions obtained from each investee's business plan. Also, a discount rate is determined on the basis of the general economic situation and of that of each investee in particular. Procedures applied in the audit Our audit procedures to address this matter included, among others, the evaluation of the criteria used by the Company in the process to assess the existence of objective evidence of impairment of the ownership interests in Group companies and associates. In addition, for the investments for which I there were indications of impairment, we obtained and analysed the impairment tests carried out by the Company and verified their clerical accuracy, analysing, also, the consistency of the future cash flow projections considered in those tests with the most recent business plans prepared by each investee. In addition, we evaluated the reasonableness of the key assumptions considered in the aforementioned tests (such as revenue growth, cost inflation and the discount rate), and performed a sensitivity analysis of those key assumptions and a review of their consistency with the actual data relating to the performance of the investments held on which the corresponding impairment tests was conducted. - 2 -

Description The preparation of the aforementioned impairment tests requires the Company's directors to make significant judgements and estimates. As a result of the foregoing, and of the significance of the carrying amount of the aforementioned ownership interests in Group companies and associates, this matter was determined to be a key matter in our audit. Description As indicated in Note 17, on 29 December 2023 the Company reached an agreement with Haier Group Corporation for the sale of a 20% ownership interest in Shanghai RAAS Blood Products Co. Ltd. ("SRAAS") for CNY 12,500 million (approximately, USD 1,800 million). In addition, this sale includes the assumption of other obligations between the parties, as indicated in aforementioned Note 17 to the accompanying financial statements. Procedures applied in the audit We also involved our internal valuation experts in order to evaluate, mainly, the methodology employed by the Company in the impairment tests conducted, the discount and growth rates considered and the terminal value, expressed in perpetuity growth terms, of the projected future cash flows. Lastly, we evaluated whether the disclosures included in Notes 4.i.vi, 4.i.ix and 13 to the accompanying financial statements in connection with this matter were in conformity with those required by the applicable regulatory financial reporting framework. Procedures applied in the audit Our audit procedures included, among others, the obtainment and review of the agreement for the sale of the aforementioned ownership interest, which includes the price of the transaction and the other agreements entered into between the parties, and the evaluation of the assumptions and interpretations made by the Company's management and directors in relation to the determination of the value at which the transaction was recognised and, in particular, of the estimation of the fair value on the basis of the various obligations agreed upon by the parties. - 3 -

The aforementioned ownership interest was measured at cost, since cost was lower than the fair value less the costs of disposal reflected in the agreements described (see Note 4.w). As a result of the importance of this transaction, the occurrence of which will have a significant impact on the assessment of the Company's financial and liquidity position (see Note 12.a.iv), as well as the significance of the judgements and estimates that the Company's directors used to determine its appropriate measurement and classification in the accompanying financial statements, this matter was determined to be a key matter in our audit. Other Information: Directors' Report Procedures applied in the audit In addition, we evaluated the judgements and estimates made by the Company's directors in relation to the classification of the 20% of the carrying amount of the investment held in SRAAS under "Non-Current Assets Classified as Held for Sale" and, in particular, in relation to the consideration of the transaction as highly probable, taking into consideration, inter alia, the steps taken to date and the representations made by the buyer. Lastly, we evaluated whether the disclosures included in Notes 4.w, 12.a.iv and 17 to the accompanying financial statements in connection with this matter were in conformity with those required by the applicable regulatory financial reporting framework. The other information comprises only the directors' report for 2023, the preparation of which is the responsibility of the Company's directors and which does not form part of the financial statements. -4-

Our audit opinion on the financial statements does not cover the directors' report. Our responsibility relating to the directors' report, in accordance with the audit regulations in force, consists of: a) Solely checking that the non-financial information statement, certain information included in the Annual Corporate Governance Report and the Annual Directors' Remuneration Report, to which the Spanish Audit Law refers, have been furnished as provided for in the applicable legislation and, if this is not the case, reporting this fact. b) Evaluating and reporting on whether the other information included in the directors' report is consistent with the financial statements, based on the knowledge of the entity obtained in the audit of those financial statements, as well as evaluating and reporting on whether the content and presentation of this section of the directors' report are in conformity with the applicable regulations. If, based on the work we have performed, we conclude that there are material misstatements, we are required to report that fact. Based on the work performed, as described above, we observed that the information described in section a) above had been furnished as provided for in the applicable legislation and that the other information in the directors' report was consistent with that contained in the financial statements for 2023 and its content and presentation were in conformity with the applicable regulations. Responsibilities of the Directors and of the Audit Committee for the Financial Statements The directors are responsible for preparing the accompanying financial statements so that they present fairly the Company's equity, financial position and results in accordance with the regulatory financial reporting framework applicable to the Company in Spain, and for such internal control as the directors determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error. In preparing the financial statements, the directors are responsible for assessing the Company's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the Company or to cease operations, or have no realistic alternative but to do so. The audit committee is responsible for overseeing the process involved in the preparation and presentation of the financial statements. - 5 -

Auditor's Responsibilities for the Audit of the Financial Statements Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor1 s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with the audit regulations in force in Spain will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements. A further description of our responsibilities for the audit of the financial statements is included in the Appendix to this auditor1 s report. This description, which is on pages 8 and 9 of this document, forms part of our auditor's report. Report on Other Legal and Regulatory Requirements European Single Electronic Format We have examined the digital file in European Single Electronic Format (ESEF) of Grifols, S.A. for 2023, which comprises an XHTML file including the financial statements for 2023, which will form part of the annual financial report. The directors of Grifols, S.A. are responsible for presenting the annual financial report for 2023 in accordance with the format requirements established in Commission Delegated Regulation (EU) 2019/815 of 17 December 2018 ("ESEF Regulation11 ). In this regard, the Annual Corporate Governance Report and the Annual Directors1 Remuneration Report were included by reference in the directors1 report. Our responsibility is to examine the digital file prepared by the Company1s directors, in accordance with the audit regulations in force in Spain. Those regulations require that we plan and perform our audit procedures in order to ascertain whether the content of the financial statements included in the aforementioned file corresponds in full to that of the financial statements that we have audited, and whether those financial statements were formatted, in all material respects, in accordance with the requirements established in the ESEF Regulation. In our opinion, the digital file examined corresponds in full to the audited financial statements, and these are presented, in all material respects, in accordance with the requirements established in the ESEF Regulation. - 6 -

Appendix to our auditor's report Further to the information contained in our auditor's report, in this Appendix we include our responsibilities in relation to the audit of the financial statements. Auditor's Responsibilities for the Audit of the Financial Statements As part of an audit in accordance with the audit regulations in force in Spain, we exercise professional judgement and maintain professional scepticism throughout the audit. We also: • Identify and assess the risks of material misstatement of the financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. • Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity's internal control. • Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by the directors. • Conclude on the appropriateness of the use by the directors of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company's ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor's report to the related disclosures in the financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor's report. However, future events or conditions may cause the Company to cease to continue as a going concern. • Evaluate the overall presentation, structure and content of the financial statements, including the disclosures, and whether the financial statements represent the underlying transactions and events in a manner that achieves fair presentation. We communicate with the entity's audit committee regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit. - 8 -

We also provide the entity's audit committee with a statement that we have complied with relevant ethical requirements, including those regarding independence, and we have communicated with it to report on all matters that may reasonably be thought to jeopardise our independence, and where applicable, on the related safeguards. From the matters communicated with the entity's audit committee, we determine those matters that were of most significance in the audit of the financial statements of the current period and are therefore the key audit matters. We describe these matters in our auditor's report unless law or regulation precludes public disclosure about the matter. - 9 -

9 GRIFOLS, S.A. Notes to the Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) (1) Nature and Activities of the Company and Composition of the Group Grifols, S.A. (hereinafter the “Company”) was incorporated with limited liability under Spanish law on 22 June 1987. Its registered office is in Barcelona. The Company's statutory activity consists of providing corporate and business administrative, management and control services, as well as investing in assets and property. Its principal activity involves rendering administrative, management and control services to its subsidiaries. Its main facilities are located in Sant Cugat del Vallès (Barcelona) and Parets del Vallès (Barcelona). Grifols, S.A.’s shares are listed on the Barcelona, Madrid, Valencia and Bilbao stock exchanges and on the electronic stock market. As of 2 June 2011, the class B non-voting shares were listed on the NASDAQ (USA) and the Automated Quotation System (SIBE/Continuous Market). In accordance with prevailing legislation, the Company is the Parent of a Group comprising the Company and the subsidiaries, associated and multi-group companies listed in Note 13 and the Appendix II. In accordance with generally accepted accounting principles in Spain, consolidated annual accounts must be prepared to give a true and fair view of the financial position of the Group, the results of operations and changes in its equity and cash flows. On 7 March 2024 the Company’s board of directors authorised for issue the consolidated annual accounts of Grifols, S.A. and subsidiaries for 2023 prepared in accordance with International Financial Reporting Standards as adopted by the European Union (IFRS-EU), which show consolidated profit attributable to the Parent of Euros 59,315 thousand, total assets Euros 21,441,054 thousand and consolidated equity of Euros 7,972,485 thousand (Euros 208,279 thousand, Euros 21,533,977 thousand and Euros 8,457,544 thousand, respectively, in 2022). (2) Basis of Presentation (a) True and fair view The accompanying annual accounts have been prepared on the basis of the accounting records of Grifols, S.A. The annual accounts for 2023 have been prepared in accordance with prevailing legislation and the Spanish General Chart of Accounts to give a true and fair view of the equity and financial position of the Company at 31 December 2023 and results of operations, changes in equity, and cash flows for the year then ended. The directors consider that the annual accounts for 2023, authorised for issue on 7 March 2024, will be approved with no changes by the shareholders at their annual general meeting. (b) Comparative information The balance sheet, income statement, statement of changes in equity, statement of cash flows and the notes thereto for 2023 include comparative figures for 2022, which formed part of the annual accounts approved by the shareholders at the annual general meeting held on 16 June 2023. (c) Functional and presentation currency The figures disclosed in the annual accounts are presented in Euros thousand, the Company’s functional and presentation currency, rounded off to the nearest Euro thousand. (d) Critical issues regarding the valuation and estimation of relevant uncertainties and judgements used when applying accounting principles. Relevant accounting estimates and judgements and other estimates and assumptions have to be made when applying the Company’s accounting principles to prepare the annual accounts. A summary of the items requiring a greater degree of judgement, or which are more complex, or where the assumptions and estimates made are significant to the preparation of the annual accounts, is as follows:

10 GRIFOLS, S.A. Notes to the Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) (i) Relevant accounting estimates and assumptions The Company tests investments in Group companies for impairment when there are signs that the book value is lower than the recoverable value, understood as the higher amount between the fair value less costs of sales and usage value. The determination of the recoverable value implies the use of estimates made by management. The Company generally uses cash flow discounting methods to calculate this value. Cash flow discounting calculations are based on the 5-year projections of the budgets approved by management. The cash flows take into consideration past experience and represent management’s best estimate of future market performance. The fifth-year cash flows are extrapolated using individual growth rates. The key assumptions employed include growth rates and the discount rate. The estimates, including the methodology used, could have a significant impact on values and impairment. Additionally, the Company has considered as relevant judgment the classification of the 20% ownership held in Shanghai RAAS Blood Products Co. Ltd. as a non-current asset held for sale. (ii) Changes in accounting estimates Although estimates are calculated by the Company’s directors based on the best information available at 31 December 2023, future events may require changes to these estimates in subsequent years. Any effect on the annual accounts of adjustments to be made in subsequent years would be recognised prospectively. Grifols, S.A. management does not consider that there are any assumptions or sources of uncertainty that would have a significant risk of resulting in a material adjustment within the next financial year. (3) Distribution of Profit The distribution of profit and reserves of the Company for the year ended 31 December 2022, approved by the shareholders at their annual general meeting held on 16 June 2023, was as follows: The proposed distribution of losses for the year ended 31 December 2023 to be submitted to the shareholders for approval at their annual general meeting is as follows: Thousand Euros Basis of allocation Losses for the year (246,735) Allocation Voluntary reserve (246,735) Thousand Euros Basis of allocation Losses for the year (266,296) Allocation Voluntary reserve (266,296)

11 GRIFOLS, S.A. Notes to the Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) As of December 31, 2023 and 2022, non-distributable reserves are as follows: 2023 2022 Non-distributable reserves Legal reserve 23,921 23,921 Other 3 3 23,924 23,924 Thousand Euros Profit recognised directly in equity cannot be distributed, either directly or indirectly. (4) Significant Accounting Policies (a) Business combinations Business combinations are accounted for by applying the acquisition method, for which the acquisition date is determined and the cost of the combination is calculated, recording the identifiable assets acquired and liabilities assumed at their fair value as of that date. The cost of the combination is determined by the aggregation of: - The fair values at the acquisition date of assets transferred, liabilities incurred or assumed, and equity instruments issued. - The fair value of any contingent consideration that depends on future events or the fulfilment of predetermined conditions. Expenses related to the issuance of equity instruments or financial liabilities exchanged for the acquired items are not part of the cost of the combination. Similarly, fees paid to legal advisors or other professionals involved in the combination, as well as internally generated expenses related to these matters, are not part of the cost of the combination. These amounts are directly charged to the income statement. (b) Foreign currency transactions, balances and cash flows Foreign currency transactions have been translated into Euros using average exchange rates for the prior month for all foreign currency transactions during the current month. This method does not differ significantly from applying the exchange rate at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies have been translated into Euros at the closing rate, while non-monetary assets and liabilities measured at historical cost have been translated at the exchange rate prevailing at the transaction date. In the statement of cash flows, cash flows from foreign currency transactions have been translated into Euros using the average exchange rates for the prior month for all flows that occur during the following month. This method does not differ significantly from applying the exchange rate at the date of the transaction. Exchange gains and losses arising on the settlement of foreign currency transactions and the translation into Euros of monetary assets and liabilities denominated in foreign currencies are recognised in profit and loss. (c) Capitalised borrowing costs In accordance with the second transitional provision of Royal Decree 1514/2007 enacting the Spanish General Chart of Accounts, the Company has opted to apply this accounting policy to work in progress at 1 January 2008 which will not be available for use, capable of operating or available for sale for more than one year. Until that date, the Company opted to recognise borrowing costs as an expense as they were incurred.

12 GRIFOLS, S.A. Notes to the Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) Borrowing costs related to specific and general financing that are directly attributable to the acquisition, construction or production of intangible assets, property, plant and equipment and investment property that will not be available for use, capable of operating or available for sale for more than one year are included in the cost of the asset. To the extent that funds are borrowed specifically for the purpose of obtaining a qualifying asset, the amount of borrowing costs eligible for capitalisation is determined as the actual borrowing costs incurred. Non-commercial general borrowing costs eligible for capitalisation are calculated as the weighted average of the borrowing costs applicable to the Company’s outstanding borrowings during the period, other than those specifically for the purpose of obtaining a qualifying asset and the portion financed using equity. The borrowing costs capitalised cannot exceed the borrowing costs incurred during that period. The Company begins capitalising borrowing costs as part of the cost of a qualifying asset when it incurs expenditures for the asset, interest is accrued, and it undertakes activities that are necessary to prepare the asset for its intended use, operation or sale, and ceases capitalising borrowing costs when all or substantially all the activities necessary to prepare the qualifying asset for its intended use, operation or sale are complete, even though the necessary administrative permits may not have been obtained. Interruptions in the active development of a qualifying asset are not considered. Nonetheless, restated advances on account are not qualifying assets for the purpose of capitalising borrowing costs. Capitalised borrowing costs are recognised in the income statement under capitalised borrowing costs. (d) Intangible assets Intangible assets are measured at cost or cost of production. Capitalised production costs are recognised under “self-constructed assets” in the income statement. Intangible assets are carried at cost, less any accumulated amortisation and impairment. Advances on account of fixed assets are initially measured at cost. In subsequent years, advances accrue interest at the supplier's incremental borrowing rate when the period between payment and the receipt of the asset exceeds one year. Cost of production of intangible assets comprises the purchase price and any costs directly related to production. Expenditure on activities that contribute to increasing the value of the Company’s business as a whole, such as goodwill, trademarks and other similar items generated internally, as well as establishment costs, are recognised as expenses on the income statement when incurred. (i) Computer software Computer software acquired and developed by the Company is recognised to the extent that costs can be clearly allocated, expensed and distributed over time to each project, and when there is evidence of technical success and economic viability. Computer software maintenance costs are charged as expenses when incurred. (ii) Subsequent costs Subsequent costs incurred on intangible assets are recognised in profit and loss, unless they increase the expected future economic benefits attributable to the intangible asset. (iii) Useful life and amortisation rates Intangible assets with finite useful lives are amortised by allocating the depreciable amount of an asset on a systematic basis over its useful life, by applying the following criteria: Depreciation method Rates % Computer software Straight-line 16‑33 The depreciable amount is the acquisition or production cost of an asset.

13 GRIFOLS, S.A. Notes to the Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) The Company considers that the residual value of the assets is zero unless: - There is a commitment by a third party to purchase the asset at the end of its useful life. - There is an active market for the intangible asset and: Residual value can be determined by reference to that market; and It is probable that such market will exist at the end of the asset's useful life. The Company reviews the useful life and amortisation method for intangible assets at each financial year end. Changes to initially established criteria are accounted for as a change in accounting estimates. (iv) Impairment losses The Company measures and determines impairment to be recognised or reversed based on the criteria in section (g) Impairment of non-financial assets subject to amortisation or depreciation. (e) Property, plant and equipment (i) Initial recognition Property, plant and equipment are measured at cost of acquisition or production, using the same criteria as for determining the cost of production of intangible assets. Capitalised production costs are recognised under “Self-constructed assets” in the income statement. Property, plant and equipment are carried at cost less any accumulated depreciation and impairment. The cost of an item of property, plant and equipment includes the estimated costs of its dismantling or removal and restoration of the site on which it is located, provided that the obligation is incurred as a consequence of having used the item. (ii) Property, plant and equipment swap Property, plant and equipment acquired in exchange for one or more non-monetary assets or a combination of monetary and non-monetary assets, is recognized for the monetary amount delivered plus the fair value of the non-monetary assets delivered in the transaction, except in those cases in which those that do not have a commercial substance or for which the fair value of the property, plant and equipment received or the asset delivered cannot be reliably measured. The fair value of the asset received should be recognized by reference to the fair value of the asset delivered except in those transactions in which the fair value of the asset received can be determined with greater reliability. In those cases in which the fair value of the asset received or delivered cannot be determined reliably or in which the transaction lacks commercial substance, the acquisition cost is determined by reference to the net book value of the asset delivered, plus, where appropriate, the monetary counterparts paid or pending payment, with the limit of the fair value of the asset received if it were less. (iii) Depreciation Property, plant and equipment are depreciated by allocating the depreciable amount of the asset on a systematic basis over its useful life. The depreciable amount is the cost of an asset. The Company determines the depreciation charge separately for each component of an item of property, plant and equipment with a cost that is significant in relation to the total cost of the asset and with a useful life that differs from the remainder of the asset.

14 GRIFOLS, S.A. Notes to the Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) Property, plant and equipment are depreciated using the following criteria: Depreciation method Rates % Buildings Straight-line 2 Technical installations and machinery Straight-line 10 Other installations, equipment and furniture Straight-line 4‑10 Other property, plant and equipment Straight-line 7‑33 The Company reviews useful lives and depreciation methods at each financial year end. Changes to initially established criteria are accounted for as a change in accounting estimates. (iv) Subsequent costs Subsequent to initial recognition of the asset, only the costs incurred which increase capacity or productivity or which lengthen the useful life of the asset are capitalised. The carrying amount of parts that are replaced is derecognised. Costs of day-to-day servicing are recognised in profit and loss as incurred. Replacements of property, plant and equipment that qualify for capitalisation are recognised as a reduction in the carrying amount of the items replaced. Where the cost of the replaced items has not been depreciated independently and it is not possible to determine the respective carrying amount, the replacement cost is used as indicative of the cost of items at the time of acquisition or construction. (v) Impairment The Company measures and determines impairment to be recognised or reversed based on the criteria in section (g) Impairment of non-financial assets subject to amortisation or depreciation. (f) Investment property The Company classifies property leased to its subsidiaries under this caption. Property that is being constructed or developed for future use as investment property is classified as property, plant and equipment under development until construction or development is complete. Nevertheless, redevelopment work to extend or improve property is classified as investment property. The Company measures and recognises investment property following the policy for property, plant and equipment. The Company reclassifies property, plant and equipment to investment property when it ceases to use the building in the production or supply of goods or services, for administrative purposes or when it is held to earn rentals or for capital appreciation or both. Investment property is depreciated applying the following policies: Depreciation method Rates % Buildings and other installations Straight-line 1‑10 (g) Impairment of non-financial assets subject to amortisation or depreciation The Company evaluates whether there are indications of possible impairment losses on non-financial assets subject to amortisation or depreciation to verify whether the carrying amount of these assets exceeds the recoverable amount. The recoverable amount is the higher of the fair value less costs to sell and the value in use. Impairment losses are recognised in the income statement.

15 GRIFOLS, S.A. Notes to the Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) At the end of each reporting period the Company assesses whether there is any indication that an impairment loss recognised in prior periods may no longer exist or may have decreased. Impairment losses on goodwill are not reversible. Impairment losses on other assets are only reversed if there has been a change in the estimates used to calculate the recoverable amount of the asset. A reversal of an impairment loss is recognised in the income statement. The increased carrying amount of an asset attributable to a reversal of an impairment loss may not exceed the carrying amount that would have been determined, net of depreciation or amortisation, had no impairment loss been recognised. After an impairment loss or reversal of an impairment loss is recognised, the depreciation (amortisation) charge for the asset is adjusted in future periods based on its new carrying amount. However, if the specific circumstances of the assets indicate an irreversible loss, this is recognised directly in losses on the disposal of fixed assets in the income statement. (h) Leases (i) Lessor accounting Leases which, on inception, transfer to third parties substantially all the risks and rewards incidental to ownership of the assets are classified as finance leases, otherwise they are classified as operating leases. (ii) Lessee accounting Leases in which, upon inception, the Company assumes substantially all the risks and rewards incidental to ownership are classified as finance leases, otherwise they are classified as operating leases. - Finance leases At the commencement of the lease term, the Company recognises finance leases as assets and liabilities at the lower of the fair value of the leased asset and the present value of the minimum lease payments. Initial direct costs are added to the asset’s carrying amount. Minimum lease payments are apportioned between the finance charge and the reduction of the outstanding liability. Interest is expensed using the effective interest method. Contingent rents are recognised as an expense when it is probable that they will be incurred. The accounting policies applied to the assets used by the Company by virtue of finance lease contracts are the same as those set out in sections (e) and (f) (Property, plant and equipment or Investment Property). - Operating leases Lease payments under an operating lease, net of incentives received, are recognised as an expense on a straight-line basis over the lease term. Contingent rents are recognised as an expense when it is probable that they will be incurred. (i) Financial instruments (i) Classification of financial instruments Financial instruments are classified at the time of their initial recognition as a financial asset, a financial liability or an equity instrument, in accordance with the economic substance of the contractual agreement and with the definitions of financial assets, financial liabilities or equity instruments.

16 GRIFOLS, S.A. Notes to the Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) For valuation purposes, the Company classifies financial instruments in the following categories: financial assets and liabilities valued at amortised cost; financial assets and liabilities at fair value through profit or loss, by considering separately those initially designated from those held for trading and those compulsorily valued at fair value through profit or loss; financial assets measured at fair value through equity, by considering separately the equity instruments designated as such from the rest of the financial assets; and financial assets valued at cost. The Company classifies a financial asset at amortised cost if it is held in the framework of a business model whose objective is to hold financial assets to obtain contractual cash flows and the contractual terms of the financial asset give rise, on specified dates, to cash flows which are only principal and interest payments on the outstanding principal amount (OPIP). The Company classifies as a financial asset at fair value through equity those financial assets whose contractual conditions, on specified dates, result in cash flows that are solely receipts of principal and interests on the outstanding principal amount, and they are not held for trading nor classified in the previous category. In this category are also included the investments in equity instruments designated irrevocably by the Company at the time of its initial recognition, as far as they are not held for trading and should not be valued at cost. The Company classifies as a financial asset at fair value through profit or loss those financial assets held for trading and those financial assets that have not been classified in any of the previous categories. In this category are also included the financial assets that the Company optionally designates at the time of the initial recognition, which otherwise would have been included in another category, as such designation eliminates or significantly reduces a valuation inconsistency or accounting asymmetry. The Company classifies a financial asset at cost when it is an (i) investment in the equity of group, multigroup and associates (ii) participating loans with contingent interests, either because a fixed or conditional variable interest rate is conditioned to the fulfilment of a milestone in the borrowing company, or because they are calculated exclusively with respect to the evolution of the activity of the aforementioned company. The Company classifies its financial liabilities at amortised cost. (ii) Valuation At the time of initial recognition, the Company values a financial asset at its fair value plus, in the case of a financial asset that is not at fair value through profit or loss, the costs of the transaction that are directly attributable to the acquisition. The transaction costs of financial assets at fair value through profit or loss are taken to results. In order to determine the fair value of financial assets or liabilities, the Company uses market data as much as possible. Based on the factors used for the measurement, the fair values are hierarchized based on the following factors: Level 1: estimates based on quoted prices (unadjusted) within current markets for assets or liabilities identical to those that the company may have access at the valuation date; Level 2: estimates based on quoted prices in active markets for similar instruments or other valuation methodologies in which all significant variables are based on directly or indirectly observable market data; or Level 3: estimates based on any significant variable that is not based on observable market data. In the event that the factors used to determine the fair value of an asset or liability are included in different levels of hierarchy, the fair value will be determined in its entirety based on the significant component located at the lowest level of hierarchy. (iii) Offsetting principles A financial asset and a financial liability are offset only when the Company currently has the legally enforceable right to offset the recognised amounts and intends either to settle on a net basis or to realise the asset and settle the liability simultaneously.

17 GRIFOLS, S.A. Notes to the Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) (iv) Financial assets and liabilities at fair value through profit or loss Financial assets and financial liabilities at fair value through profit or loss are initially recognised at fair value. Transaction costs directly attributable to the acquisition or issue are recognised as an expense when incurred. After initial recognition, they are recognized at fair value through profit or loss. Changes in the fair value include the component of interest and dividends. The fair value is not reduced by the transaction costs that may be incurred by their eventual sale or disposal by other means. (v) Financial assets and liabilities at amortised cost Financial assets and financial liabilities at amortised cost are initially recognized at their fair value, including the transaction costs incurred, and are subsequently measured at amortised cost, using the effective interest method. (vi) Investments in Group companies and associates Group companies are those over which the Company, either directly, or indirectly through subsidiaries, exercises control as defined in article 42 of the Spanish Code of Commerce, or when the companies are controlled by one or more individuals or entities acting jointly or under the same management through agreements or statutory clauses. Control is the power to govern the financial and operating policies of an entity or business so as to obtain benefits from its activities. In assessing control, potential voting rights held by the Company or other entities that are exercisable or convertible at the end of each reporting period are considered. Associates are entities over which the Company, either directly, or indirectly through subsidiaries, exercises significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee but is not control or joint control over those policies. The existence of potential voting rights that are exercisable or convertible at the end of each reporting period, including potential voting rights held by the Company or other entities, are considered when assessing whether an entity has significant influence. Investments in Group companies and associates are initially recognised at cost, which is equivalent to the fair value of the consideration given, including transaction costs in the case of investments in associates, and are subsequently measured at cost net of any accumulated impairment. The cost of investments in Group companies acquired before 1 January 2010 includes any transaction costs incurred. If an investment no longer qualifies for classification under this category, it is reclassified at fair value through profit or loss, unless it is designated at fair value through equity and it is valued as such from the date of reclassification, recognizing any difference in the profit or loss or in equity, respectively. In non-monetary business contributions to other group companies, including investments in group companies, the equity investments received are valued at the date the operation is carried out, for the amount representing the percentage of participation equivalent to the book value of the net assets of the investment contributed in the consolidated financial statements of the largest group whose parent company is Spanish according to the Standards for the Formulation of Consolidated Annual Accounts, plus transaction costs. Any difference between the book value of the investments received and the book value of the equity elements delivered (or the investment contributed), is recognized in reserves. The Company recognizes the amount contributed in a capital increase, including the preferential subscription rights acquired, as a higher value of the equity instruments. However, when the Company does not contribute proportionally to its stake in the issuer, it recognizes the difference as a donation expense. If the Company receives an asset or group of assets other than cash, the swap criteria previously indicated for non-monetary contributions are applied.

18 GRIFOLS, S.A. Notes to the Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) (vii) Reclassifications of financial instruments The Company reclassifies a financial asset when the business model for its management is modified or when it meets or no longer meets the aforementioned classification criteria. The Company does not reclassify financial liabilities. (viii) Derecognition of financial assets The Company applies the criteria for the derecognition of financial assets to a part of a financial asset or to a part of a group of similar financial assets or to a financial asset or a group of similar financial assets. Financial assets are derecognized when the rights to receive cash flows related to them have expired or have been transferred and the Company has substantially transferred the risks and rewards derived from their ownership. (ix) Impairment of financial assets A financial asset or a group of financial assets is impaired and impairment losses are incurred if there is objective evidence of impairment as a result of one or more events that occurred after the initial recognition of the asset and the event or events have an impact on the estimated future cash flows of the financial asset or group of financial assets that can be reliably estimated. Impairment of financial assets valued at amortised cost The loss due to an impairment of financial assets valued at amortised cost is the difference between the book value of the financial asset and the present value of the estimated future cash flows. However, the Company uses the financial assets market value, as long as it is reliable enough to be considered representative of the value to be recovered. The impairment loss is recognized with charge to profit or loss and it is reversible in subsequent years, if the decrease can be objectively related to an event subsequent to its recognition. However, the reversal of the loss is limited to the amortised cost that the assets had if the loss due to the impairment in value had not been recorded. The Company directly reduces the carrying amount of a financial asset when it does not have reasonable expectations of full or partial recovery. Investments in Group companies Impairment is calculated by comparing the carrying amount of the net investment in the associate with its recoverable amount. The recoverable amount is the higher of value in use and fair value less costs to sell. Value in use is calculated based on the Company’s share of the present value of future cash flows expected to be derived from ordinary activities and from the disposal of the asset. Unless better evidence is available, the investee’s equity is taken into consideration, corrected for any unrealised gains existing at the measurement date. In subsequent years, reversals of impairment losses in the form of increases in the recoverable amount are recognised, up to the limit of the carrying amount that would have been determined for the investment if no impairment loss had been recognised. The recognition or reversal of an impairment loss is disclosed in the income statement unless it should be recognised in equity. Impairment of an investment is limited to the amount of the investment, except when contractual, legal or constructive obligations have been assumed by the Company or payments have been made on behalf of the companies. In the latter case, provision is made.

19 GRIFOLS, S.A. Notes to the Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) (x) Derecognition and modifications of financial liabilities The Company derecognises all or part of a financial liability when it either discharges the liability by paying the creditor or is legally released from primary responsibility for the liability either by process of law or by the creditor. The exchange of debt instruments between the Company and the counterparty or substantial modifications of initially recognised liabilities are accounted for as an extinguishment of the original financial liability and the recognition of a new financial liability, provided that the instruments have substantially different terms. The Company considers the terms to be substantially different if the discounted present value of the cash flows under the new terms, including any fees paid net of any fees received and discounted using the original effective interest rate, is at least 10 per cent different from the discounted present value of the remaining cash flows of the original financial liability. If the exchange is accounted for as an extinguishment of the financial liability, any costs or fees incurred are recognised as part of the gain or loss on the extinguishment. If the exchange is not accounted for as an extinguishment, any costs or fees incurred adjust the carrying amount of the liability and are amortised over the remaining term of the modified liability. The difference between the carrying amount of a financial liability, or part of a financial liability, extinguished or transferred to another party and the consideration paid, including any non-cash assets transferred or liabilities assumed, is recognised in profit or loss. However, the Company may designate the financial guarantee to be measured at fair value through profit or loss. (xi) Reverse factoring The Company has contracted reverse factoring facilities with various financial institutions to manage payments to suppliers. Trade payables settled under the management of financial institutions are recognised under “trade and other payables” in the balance sheet until they are settled, repaid or have expired. (j) Hedge accounting Derivative financial instruments are initially recognized following the criteria set forth above for financial assets and liabilities. Derivative financial instruments that do not meet the hedge accounting criteria are classified and valued as financial assets or liabilities at fair value through profit or loss. (k) Own equity instruments held by the Company Equity instruments acquired by the Company are shown separately at cost of acquisition as a reduction in capital and reserves in the balance sheet. Any gains or losses on transactions with own equity instruments are not recognised in profit or loss. Transaction costs related to own equity instruments, including issue costs related to a business combination, are accounted for as a deduction from reserves, net of any tax effect. (l) Inventories (i) General Inventories are measured using the FIFO (first in, first out) method. When the cost of inventories exceeds replacement value, materials are written down to net realisable value. Inventories are mainly spare parts used to maintain the Company’s buildings and facilities. Emission allowances Emission allowances acquired are classified and measured by applying accounting policies.

In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) (m) Cash and cash equivalents Cash and cash equivalents include cash on hand and demand deposits in financial institutions. They also include other short-term, highly liquid investments that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value. An investment normally qualifies as a cash equivalent when it has a maturity of less than three months from the date of acquisition. (n) Grants Grants are recorded in recognised income and expense when, where applicable, they have been officially awarded and the conditions attached to them have been met or there is reasonable assurance that they will be received. Grants that are given to finance specific expenses are recognised as income in the same year as the finance cost is accrued. (o) Defined contribution plans The Company recognises the contributions payable to a defined contribution plan in exchange for a service when an employee has rendered service to the Company. The contributions payable are recognised as an expense for employee remuneration and as a liability after deducting any contribution already paid. If the contribution already paid exceeds the contribution due for service before the end of the period, the Company only recognises that excess as an asset (prepaid expense) to the extent that the prepayments will lead to, for example, a reduction in future payments or cash refund. (p) Provisions (i) General criteria Provisions are recognised when the Company has a present obligation (legal, contractual, constructive or tacit) as a result of a past event; it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation; and a reliable estimate can be made of the amount of the obligation. The amount recognised as a provision is the best estimate of the expenditure required to settle the present obligation at the end of the reporting period, taking into account all risks and uncertainties surrounding the amount to be recognised as a provision and, where the time value of money is material, the financial effect of discounting provided that the expenditure to be made each period can be reliably estimated. The discount rate is a pre-tax rate that reflects the time value of money and the specific risks for which future cash flows associated with the provision have not been adjusted at each reporting date. If it is not probable that an outflow of resources will be required to settle an obligation, the provision is reversed. (ii) Provisions for taxes Provisions for taxes are measured at the estimated amount of tax debt calculated in accordance with the aforementioned criteria. Provision is made with a charge to income tax for the tax expense for the year, to finance costs for the late payment interest, and to other income for the penalty. The effects of changes in estimates of prior years’ provisions are recognised according to their nature, unless they involve the correction of an error. (q) Revenue (i) Revenue from the rendering of services Revenue from the rendering of services is measured at the fair value of the consideration received or receivable. Practically all services are rendered to Group companies.

21 GRIFOLS, S.A. Notes to the Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) (ii) Interests and dividends The Company recognizes interests and dividends on financial assets accrued after the acquisition date as income in the profit and loss. The Company recognizes interests on financial assets valued at amortised cost using the effective interest method and dividends when the Company is entitled to receive them. In the initial valuation of financial assets, the Company records separately, based on their maturity, the amount of explicit interest accrued and not due at that time, as well as the amount of dividends agreed by the competent authority at the time of the acquisition. As a result, these amounts are not recognized as income in the profit or loss. If the dividends are clearly derived from profits generated prior to the acquisition date because amounts higher than the profits generated by the investment since the acquisition have been distributed, the carrying amount of the investment is reduced. This criterion is applied regardless of the valuation criterion used for the equity instruments, so for equity instruments valued at fair value, the value of the investment is also reduced and an increase in subsequent value in the profit or loss account or in equity is recognized, based on the instruments classification. The Company recognizes the dividends received by the delivery of an equity element or group of equity elements other than cash, in accordance with the previously indicated criteria. However, if the dividend is received as a business of a group company, the criteria indicated in BOICAC 85 should be applied. Interest and dividend income are classified as revenue when they form part of the Company’s ordinary activity. (r) Income tax The income tax expense or tax income for the year comprises current tax and deferred tax. Current tax assets or liabilities are measured at the amount expected to be paid to or recovered from the taxation authorities, using the tax rates and tax laws that have been enacted or substantially enacted at the reporting date. Current and deferred tax are recognised as income or an expense and included in profit or loss for the year, except to the extent that the tax arises from a transaction or event which is recognised, in the same or a different year, directly in equity, or from a business combination. Government assistance provided in the form of deductions and other tax relief applicable to income tax payable is recognised as a reduction in the income tax expense in the year in which it is accrued. The Company files consolidated tax returns with its Spanish subsidiaries: Laboratorios Grifols, S.A., Instituto Grifols, S.A., Grifols Movaco, S.A., Biomat, S.A., Grifols International, S.A., Araclon Biotech, S.L., Grifols Engineering, S.A., Grifols Viajes S.A., Aigües Minerals de Vilajuïga, S.A. and Biotest Medical S.L.U. In addition to the factors to be considered for individual taxation, set out previously, the following factors are taken into account when determining the accrued income tax expense for the companies forming the consolidated tax group: - Temporary and permanent differences arising from the elimination of profits and losses on transactions between Group companies, derived from the process of determining consolidated taxable income. - Deductions and credits corresponding to each company forming the consolidated tax group. For these purposes, deductions and credits are allocated to the company that carried out the activity or obtained the profit necessary to obtain the right to the deduction or tax credit. Temporary differences arising from the elimination of profits and losses on transactions between tax group companies are allocated to the company which recognised the profit/loss and are valued using the tax rate of that company.

22 GRIFOLS, S.A. Notes to the Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) A reciprocal credit and debit arises between the companies that contribute tax losses to the consolidated Group and the rest of the companies that offset those losses. Where a tax loss cannot be offset by the other consolidated Group companies, these tax credits for loss carryforwards are recognised as deferred tax assets using the applicable recognition criteria, considering the tax group as a taxable entity. The Parent of the Group records the total consolidated income tax payable under payable to Group companies. The amount of the debt relating to the subsidiaries is recognised as receivables from Group companies. (i) Deferred Tax liabilities Deferred tax liabilities derived from taxable temporary differences are recognised in all cases except where they arise from the initial recognition of goodwill or an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither accounting profit nor taxable income. (ii) Deferred Tax assets Deferred tax assets derived from deductible temporary differences are recognised provided that it is probable that sufficient taxable income will be available against which they can be utilised or when the tax legislation considers the possibility to convert future assets for deferred taxes on receivables in front of the Public Administration. Nonetheless, assets arising from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither accounting profit nor taxable income, are not recognised. (iii) Measurement Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the years when the asset is realised or the liability is settled, based on tax rates and tax laws that have been enacted or substantially enacted. The tax consequences that would follow from the manner in which the Company expects to recover or settle the carrying amount of its assets or liabilities are also reflected in the measurement of deferred tax assets and liabilities. (iv) Offset and classification The Company only offsets tax assets and liabilities if it has a legally enforceable right to offset the recognised amounts and intends either to settle on a net basis or to realise the assets and settle the liabilities simultaneously. Deferred tax assets and liabilities are recognised in the balance sheet under non-current assets or liabilities, irrespective of the expected date of recovery or settlement. (s) Share-based payment transactions The Company has granted various equity-based compensation plans to certain members of the management team who are serving the company, which will be settled with either equity instruments or in cash, depending on the plan. The granted equity instruments become irrevocable when employees complete a certain service period and meet the objectives established in the incentive plan. Grifols recognizes the services received from its employees as such services are rendered during the irrevocable period, as a personnel expense in the income statement, and on the other hand, the corresponding increase in equity if the transaction is settled with equity instruments or the corresponding liability if the transaction is settled in cash, with an amount based on the value of the equity instruments. In transactions with employees settled with equity instruments, the recognized amount corresponds to the amount that will be settled once the agreed conditions are met and will not be revised or revalued during the accrual period, as the commitment is settled in shares. If an employee resigns before the accrual period ends, they will only receive the agreed incentive in shares. The fair value of the services received is estimated by estimating the fair value of the shares granted at the grant date, net of estimated dividends to which the employee is not entitled during the performance period.

23 GRIFOLS, S.A. Notes to the Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) In plans settled in cash, the services received and the corresponding liability are recognized at the fair value of the liability, as of the date the recognition criteria are met. Subsequently, and until settlement, the corresponding liability will be valued at its fair value at the end of each reporting period, with any changes in valuation during the period charged to the income statement. The fair value is determined by reference to the market value of the shares at the date of estimation, net of estimated dividends to which the employee is not entitled during the performance period. The Company assumes the payment related to employees of other group companies. Therefore, the Company recognizes the accrued cost of the plan in accordance with the criteria set out above as an increase in the investment in the subsidiary with credit to the "Other equity instruments" heading if the transaction is settled with equity instruments, or as a liability if the transaction is settled in cash. (t) Classification of assets and liabilities as current and non-current The Company classifies assets and liabilities in the balance sheet as current and non-current. Current assets and liabilities are determined as follows: - Assets are classified as current when they are expected to be realised or are intended for sale or consumption in the Company’s normal operating cycle, they are held primarily for the purpose of trading, they are expected to be realised within twelve months after the reporting date or are cash or a cash equivalent. - Liabilities are classified as current when they are expected to be settled in the Company’s normal operating cycle, they are held primarily for the purpose of trading, or they are due to be settled within twelve months after the reporting date. (u) Environmental issues The Company takes measures to prevent, reduce or repair the damage caused to the environment by its activities. Expenses derived from environmental activities are recognised as other operating expenses in the period in which they are incurred. Property, plant and equipment acquired by the Company to minimise the environmental impact of its activity and protect and improve the environment, including the reduction and elimination of future pollution from the Company’s activities, are recognised as assets applying the measurement, presentation and disclosure criteria described in section (e) Property, plant and equipment. (v) Transactions between Group companies Transactions between Group companies, except those related to mergers, spin-offs and non-cash business contributions, are recognised at the fair value of the consideration given or received. The difference between this value and the amount agreed is recognised in line with the underlying economic substance of the transaction. In non-monetary contributions to Group companies, the contributor will value its interests at the carrying amount of the equity investments, in the consolidated financial statements at the date the transaction occurred. Any difference between the value assigned to the interest received by the contributor and the carrying amount of the investments contributed will be recognised in reserves. (w) Non-current assets and disposal groups held for sale All related assets and liabilities to which active efforts have been initiated for their sale, are available in their current condition for sale, and it is highly probable that the sale will be completed within the next twelve months, are classified as held for sale. These assets are presented valued at the lower of their carrying amount and fair value less costs to sell and are not subject to depreciation from the moment they are classified as non-current assets held for sale. In the event of delays caused by events or circumstances beyond the control of Grifols and if there is sufficient evidence that the commitment to the plan to sell those classified as held for sale is maintained, the classification is maintained even if the period to complete the sale extends beyond one year.

24 GRIFOLS, S.A. Notes to the Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) Non-current assets held for sale are presented on the balance sheet under the headings "Non-current assets held for sale" for assets, and "Liabilities related to non-current assets held for sale" for liabilities, if any. Additionally, discontinued operations are considered to be components (cash-generating units or groups of cash-generating units) representing a significant business unit or geographic area of operations that can be considered separate from the rest, which have been sold or disposed of by other means, or that meet the conditions to be classified as held for sale. Also, entities acquired solely for the purpose of resale are considered discontinued operations. The post-tax results of discontinued operations are presented in a single line of the income statement called "Profit (Loss) from discontinued operations net of taxes". (5) Business combinations The Company merged with Gripdan Invest, S.L. and Grifols Escrow Issuer, S.A. in 2023.

(12) Risk Management Policy (a) Financial risk factors The Company's activities are exposed to various financial risks: market risk (including currency risk, fair value interest rate risk and price risk), credit risk, liquidity risk, and cash flow interest rate risk. The Company’s global risk management programme focuses on uncertainty in the financial markets and aims to minimise potentially adverse effects on the Company’s profits. The Company’s risk management policies are established in order to identify and analyse the risks to which the Company is exposed, establish suitable risk limits and controls, and control risks and compliance with limits. Risk management procedures and policies are regularly reviewed to ensure they take into account changes in market conditions and in the Company’s activities. The Company’s management procedures and rules are designed to create a strict and constructive control environment in which all employees understand their duties and obligations. The Group’s Audit Committee supervises how management controls compliance with the Group’s risk management procedures and policies and reviews whether the risk management policy is suitable considering the risks to which the Group is exposed. This committee is assisted by Internal Audit which acts as supervisor. Internal Audit performs regular and ad hoc reviews of the risk management controls and procedures and reports its findings to the Audit Committee. Market risk Market risk is the risk that changes in market prices, for example, exchange rates, interest rates or the prices of equity instruments, affect the Company’s subsidiaries revenues or the value of the financial instruments that the Company holds. The objective of managing market risk is to manage and control the Company and its subsidiaries exposure to this risk within reasonable parameters at the same time as optimizing returns. (i) Market risk The Company is not exposed to market risks associated with non-financial assets. Even though, the Group is exposed to the price risk affecting raw materials, that is mitigated by the vertical integration of the hemoderivatives business in a highly-concentrated industry. (ii) Currency risk The Company operates internationally and is therefore exposed to currency risk when operating with foreign currencies, especially with regard to the US Dollar. Currency risk is associated with recognised assets and liabilities, and net investments in foreign operations. The Company holds several investments in foreign operations, the net assets of which are exposed to currency risk. Currency risk affecting net assets of the Company’s foreign operations in US Dollars is mitigated primarily through borrowings in the corresponding foreign currency. Details of financial assets and liabilities denominated in foreign currency, as well as transactions denominated in foreign currency are presented in the Notes 15 and 22.

In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) As mentioned in Note 16, the debt in US dollars is covered by the cross-currency swaps contracted to cover the exposure to the associated exchange rate risk. At 31 December 2023 had the US Dollar weakened by 10% against the Euro, with the other variables remaining constant, post-tax profit would have been Euros 5,512 thousand higher, mainly as a result of converting payables to Group companies (Euros 413 thousand higher at 31 December 2022). (iii) Credit risk The Company’s financial assets mainly comprise the trade receivables from and loans to Group companies. The Company considers that its financial assets are not significantly exposed to credit risk. Regarding the Company’s subsidiaries, credit risk is the risk in the event that a customer or counterparty to a financial instrument fails to discharge a contractual obligation, and mainly results from trade receivables and investments in financial assets. At 31 December 2023 the impairment of those assets has not been significant. (iv) Liquidity risk Liquidity risk is the risk to not meet the financial obligations as they fall due. Management approach to managing liquidity is to ensure where possible, that the Company always has sufficient liquidity to settle its obligations at the maturity date, both in normal conditions and in times of tension, to avoid incurring unacceptable losses or tarnishing the Group’s reputation. Management manages liquidity risk on a prudent basis, based on availability of cash and sufficient committed unused long-term credit facilities, enabling the Group to implement its business plans and carry out operations using stable and secure sources of financing. The main contractual obligations existing at the end of the year mainly comprise financial debt obligations with repayments of principal and interests, in the long term mostly (see Note 22). The Group's treasury budget anticipates meeting all its commitments in the next 12 months. Additionally, the cash generated from the divestment in Shanghai RAAS (see Note 17) and the improvement in operational cash flow will be directed towards continuing the reduction of the debt level initiated in previous years. Furthermore, the Group has various additional financing alternatives, such as negotiations with debt holders, accessing the debt market, or potential divestments in non-strategic assets, to optimize the debt structure and its financial cost. Additionally, as of December 31, 2023, the Grifols Group has a total of cash and other cash equivalents amounting to Euros 525,567 thousand (Euros 547,979 thousand as of December 31, 2022). Furthermore, the Group has approximately Euros 615,328 thousand in unused credit lines (Euros 987,340 thousand as of December 31, 2022), including Euros 544,729 thousand from the revolving credit line (Euros 937,559 thousand as of December 31, 2022). Details of financial liabilities by contractual maturity date are provided in Notes 15 and 22 (e). (v) Cash flow and fair value interest rate risks Interest rate risk arises on loans extended to Group companies and current and non-current borrowings. Borrowings and loans extended at variable interest rates expose the Company to cash flow interest rate risks. Fixed-rate borrowings expose the Company to fair value interest rate risk. The objective of interest rate risk management is to achieve a balance in the structure of the debt, keeping part of the external resources issued at a fixed rate and covering part of the variable rate debt extending loans to Group companies. At 31 December 2023, had interest rates been 100 basis points higher/lower, with the other variables remaining constant, post-tax profit would have been Euros 24,782 thousand lower/higher, mainly because of higher borrowing costs on variable interest debt (Euros 20,491 thousand at 31 December 2022).

(ii) Impairment testing At the end of the year, the Company assesses whether there are signs of impairment in each of the investments in group companies and associates. For investments in group companies and associates with signs of impairment, an estimate of the recoverable value is made, based on the present value of 5-year future cash flows approved by Management that are estimated to be received from each investment in its functional currency, discounted at a discount rate that includes the inherent risk, considering the net financial position and converting the euros at the closing exchange rate. When estimating the recoverable value, Management considered the gross margin based on the past performance and the current situation, the ongoing investments, and the national market performance expectations. Cash flows estimated as of the year in which stable growth in the financial investments has been reached are extrapolated using the estimated growth rates indicated below. Perpetual growth rates are consistent with the industry reports forecasts and the countries where the investee companies operate. For the investment in Shanghai RAAS Blood Products Co. Ltd.

In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) (16) Financial derivatives The Company uses financial derivatives to hedge against the risk that the future cash flows are exposed. In 2022, the Company considered that the requirements detailed in Note 4, regarding the registration and valuation rules, have been fulfilled in order to classify the financial instruments detailed below as hedging instruments. The Company performs an analysis to assess to what extent the changes in the cash flows of the hedging instrument would offset the changes in the cash flows of the hedged item attributable to the risk that is intended to be hedged. Taking this analysis into account, the Company determines the existence of the economic relationship and the coverage ratio. At the year-end, the Company analyses the ineffectiveness and assesses whether an economic relationship continues to exist or whether the set hedge ratio is appropriate. The possible sources of ineffectiveness considered by the Company to determine the hedging relationship and the hedge ratio are: - The hedging instrument and the hedged item have different start dates and trade dates. - The underlying of the hedged item and the hedging instrument are not homogeneous. a) Cash flow hedge As of 31 December 2023, the Company held the following hedging instruments: Thousand Dollars Asset2 Liability Liabilities issued in USD Currency swap USD/EUR exchange rate USD purchase 150,000 2024 - 5,945 - Liabilities issued in USD Currency swap USD/EUR exchange rate USD purchase 150,000 2024 - 5,940 - Liabilities issued in USD Currency swap USD/EUR exchange rate USD purchase 200,000 2024 - 7,919 - Liabilities issued in USD Currency swap USD/EUR exchange rate USD purchase 205,000 2024 (620) - 7,712 Energy price Energy swap Energy price Energy swap 2032 (21) 1,529 - 21,333 7,712 Hedging instrument Hedged risk Type Thousand Euros Notional value Due date1 Ineffectiveness recognised in profit or loss Hedging instrument fair value Hedged item (1) The maturity of the hedging instrument matches with the year when the cash flows are expected to occur and affect the profit and loss account.

In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) Cross-currency swaps The loan signed with the Group company, Grifols Escrow Issuer, S.A. amounting to US Dollars 687.4 million and maturing in October 2028, was hedged through currency swaps that convert the face value of the loan and the interest to be settled from US Dollars to Euros. During 2023, the hedge item has changed to the senior unsecured notes in US Dollars absorbed in the merger with Grifols Escrow Issuer, S.A. (see Note 5). The characteristics of the financial derivatives are as follows: On 28 June 2022 the Company entered into a fixed-for-fixed currency swap agreement with due date 15 October 2024. The agreement set the exchange of currency flows EUR-USD under the following terms: - Grifols, S.A. received a loan in euros for an amount of Euros 194 million with an interest rate of 3.10%. - Grifols S.A. granted a loan in US dollars for an amount of US Dollars 205 million with an interest rate of 4.75%. On 5 October 2021 the Company entered into a fixed-for-fixed currency swap agreement with some financial entities with due date 15 October 2024. The agreement set the exchange of currency flows EUR-USD under the following terms: - Grifols, S.A. received a loan in euros for an amount of Euros 173 million with an interest rate of 3.78%. - Grifols S.A. granted a loan in US dollars for an amount of US Dollars 200 million with an interest rate of 4.75%. On 5 October 2021 the Company entered into two fixed-for-fixed currency swap agreements with due date 15 October 2024. The agreement set the exchange of currency flows EUR-USD under the following terms: - Grifols, S.A. received a loan in euros for an amount of Euros 259 million with an interest rate of 3.59%. - Grifols S.A. granted a loan in US dollars for an amount of US Dollars 300 million with an interest rate of 4.75%. Regarding the financial derivative agreement dated on October 5, 2021, it was considered as a hedge instrument on 21 April 2022, being treated previously as a financial asset at fair value with changes in the profit or loss account. Up to that date, the impact on the profit or loss account of the fair value variations of such instrument amounted to an income of 16,646 thousand Euros, recorded under the disclosure "Fair value adjustments recognized in profit and loss" in the attached profit and loss statement. Energy swaps At the beginning of the 2023, the Company has entered into a hedge for the variation in the price of electricity. This contract has been entirely used to hedge the purchase price of electric energy against potential market price increases. The derivatives hedging the energy price meet the requirements for hedge accounting, and therefore, variations in the value of this financial instrument are recorded (net of taxes) in equity. (17) Non- currents assets held for sale On December 29, 2023, Grifols reached an agreement with Haier Group Corporation ("Haier") for the sale of a 20% equity stake in Shanghai RAAS (SRAAS) for an amount of RMB 12,500 million (approximately US Dollars 1,800 million), retaining a 6.58% stake in SRAAS. The completion of the transaction is subject to relevant regulatory approvals and confirmatory due diligence by the buyer. Both parties estimate that the closing of the transaction will occur in June 2024, although it could be postponed in the event that any regulatory approval is outstanding at that date. As part of the agreement with Haier, the parties agreed that Grifols will maintain a director on the Board of Directors of SRAAS. Grifols and SRAAS will modify the Exclusive Distribution Agreement with SRAAS to supply larger quantities of Albumin human serum in the Chinese market, to extend its current duration for an initial period of 10 years (until 2034), with SRAAS having the option to extend said term by an additional period of 10 years. Grifols and the buyer agree not to transfer any part of their shares in SRAAS for a period of 3 years after the closing of the transaction.

45 GRIFOLS, S.A. Notes to the Annual Accounts (Free translation from the original in Spanish. In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) Additionally, Grifols, S.A. commits to: - The achievement of an aggregate EBITDA in the group company Grifols Diagnostic Solutions (GDS) of US Dollars 850 million for the period 2024-2028 and if that EBITDA is not met, Grifols will compensate SRAAS with 45% of the remaining amount until reach that total amount.

With this operation, Grifols maintains its presence in China, continues with its commercial agreements with SRAAS, and at the same time, fulfils its deleveraging commitment. As of December 31, 2023, the amount equivalent to 20% of the stake in SRAAS, which amounts to Euros 1,360 million, has been reclassified to the caption Non-current assets held for sale, given that Grifols has a firm commitment to sell said participation and that its sale is considered highly probable in application of NRV 7th . This reclassification has not had an impact on the income statement as of December 31, 2023, because the sales price less costs is higher than the book value. Likewise, the sale of said participation has not been considered as discontinued operations because it does not represent a business division, or a significant separated geographical area of operations. As of the date of preparation of these financial statements, the closing of the sale of the 20% investment in SRAAS is pending approval by the competition authorities.

In the event of discrepancy, the Spanish-language version prevails) (Continued on next page) (c) Guarantees As of December 31, 2023 and 2022, the Company is guarantor in several contracts signed by its directly or indirectly participated companies, in the normal course of operations. As of December 31, 2023 and 2022, no liability associated with such guarantees is expected to arise. In particular, Grifols, S.A. acts as guarantor of the commitments acquired by a Group entity for the purchase of the 28 plasma centers to a third independent party (ImmunoTek) by an amount of US Dollars 557 million as of December 31, 2023 (US Dollars 580 million as of December 31, 2022). Grifols, S.A., through its subsidiary Grifols Shared Services North America, LLC. acts as guarantor for five plasma center lease agreements held by ImmunoTek that are not subject to this collaboration agreement up to an amount of US Dollars 50 million. In March 2019, Grifols entered into a share exchange agreement with Shanghai RAAS Blood Products Co. Ltd. (SRAAS), through which Grifols would deliver 90 shares of its US subsidiary Grifols Diagnostic Solutions Inc. (GDS) (representing 45% of the economic rights and 40% of the voting rights), and in exchange would receive 1,766 million of SRAAS shares. The agreement included a contingent consideration in the form of a minimum guarantee equivalent to the product of: (i) the difference between the accumulated EBITDA from 2019 to 2023 and US Dollars 1,300 million, and (ii) the percentage of SRAAS's participation in GDS (45%). Both at the initial moment and in each fiscal year, the fair value of the financial liability has been nil, and in the year 2023, there has been no settlement for this contingent consideration. (d) Other commitments 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 December 31, 2023, no amount has been recognized for these options as they are not significant. (21) Financial Liabilities by Category (a) Classification of financial liabilities by category The classification of financial liabilities by category and class and a comparison of the fair value with the carrying amount are provided in Appendix V.

Law 38/2022 has incorporated a temporary measure with effect for tax periods beginning in 2023, limiting the amount of the individual tax losses of each of the entities comprising the tax group for corporate income tax purposes by 50%. As of December 31, 2023, the amount recognized in deferred tax assets as a result of this limitation was Euros 37,462 thousand. In the following tax periods, this deferred asset will be integrated into the tax base in equal parts in each of the following ten tax periods beginning on January 1, 2024. From tax year 2024, the deferred asset recognized for Euros 37,462 thousand, will be reverted over the next 10 years at a rate of Euros 3,746 thousand annually. In 2021, the OECD published the Model Rules of Pillar 2 to address tax challenges arising from the digitization of the economy. This international tax system reform tackles the geographical allocation of profits for tax purposes and is designed to ensure that multinational enterprises are subject to a minimum effective tax rate of 15%. On December 15, 2022, the Council of the European Union formally adopted the European Directive on Pillar 2. It is expected that EU member states will transpose the Directive into their domestic legislation by the end of 2023. As of December 31, 2023, Spain has approved the Draft Law that transposes the European Directive to ensure a global minimum taxation of 15% for multinational corporations. This legislation will apply prospectively to accounting periods beginning on January 1, 2024. On May 23, 2023, the International Accounting Standards Board (IASB) published the International Tax Reform - Second Pillar Model Rules. Proposed amendments to IAS 12, which will be applicable for accounting periods starting from January 1, 2023. The amendments to IAS 12 provide for a mandatory temporary exemption in recognizing deferred tax balances resulting from the implementation of Pillar 2 legislation. The Group has developed an accounting policy consistent with the amendments to IAS 12, whereby the Group does not record adjustments to deferred tax assets and liabilities arising from the introduction of the minimum effective tax rate of 15%. In developing this accounting policy, the Group has also adopted the exemption provided in paragraph 98M of the amendments to IAS 12 to avoid providing detailed information on the modifications for transitional periods beginning on January 1, 2023. As of December 31, 2023, the Group continues to assess the implications of Pillar 2 reforms, including quantifying the impact on current tax due to the approval of the regulations. The assessment of potential exposure to Pillar 2 income taxes is based on the most recent tax returns, country-by-country reports, and financial statements of the Group's constituent entities. According to the assessment, effective tax rates of Pillar 2 in most jurisdictions where the Group operates are above 15%. However, there are a limited number of jurisdictions where the safe harbor transitional exemption does not apply, and the effective tax rate of Pillar 2 is close to 15%. The Group does not expect significant exposure to Pillar 2 income taxes in those jurisdictions. A reconciliation of net income and expenses for the year with the taxable income is provided in Appendix VIII. The relationship between the tax income and accounting profit for the year is shown in Appendix IX.

In accordance with prevailing tax legislation in Spain, share-based payments to employees are income tax deductible for the intrinsic amount of the share options when they are exercised, thus giving rise to a deductible temporary difference for the difference between the amount the taxation authorities will admit as a future deduction and the zero carrying amounts of the share-based payments. At the close of the reporting period, the Company estimates the future tax deduction based on the price of the shares at that time. The amount of the tax deduction is recognised as current or deferred income tax with a balancing entry in the income statement.

Although the company’s fundamentals remain sound and unchanged and all financial information was duly reported in the audited financial statements, this action had a significant impact on Grifols’ share price and corporate reputation. The company is currently working to restore the confidence of markets, shareholders and other stakeholders in three key areas: Communication and collaboration with the Spanish regulator (CNMV). Transparent communication with all our stakeholders: sharing our clear response to the published report through live conference calls and multiple official communications on the company’s website and on the CNMV portal. All press releases are publicly available on Grifols’ website: (https://www.grifols.com/es/informacion-relevante). Clear and transparent communication with our teams and employee representatives, including major unions. Reinforced communication with investors, official communications, direct phone calls, video calls and e-mails. The company filed a complaint1 in the United States District Court for the Southern District of New York against Daniel Yu, Gotham City Research LLC, General Industrial Partners LLP, Cyrus de Weck, and their affiliates to claim for the financial and reputational damages caused to Grifols and their stakeholders as a result of the defendants’ actions. The company established a dedicated working group comprising senior managers from the legal, communications, finance, investor relations and management teams, together with external advisors with expertise in communications. Following the information published by Gotham City Research LLC regarding the accounting and financial information of Grifols, S.A. and its subsidiaries, the National Securities Market Commission (CNMV), in the exercise of its supervisory powers, has made various requests for information to the Group. The parent company has provided comprehensive responses to the received requests, although as of authorised for issue date of these annual accounts, the supervisory process has not concluded. As stated in Note 17, Grifols and Haier Group Corporation ("Haier") entered into a Strategic Alliance Agreement and Share Purchase Agreement to transfer the 20% shareholding in Shanghai RAAS Blood Products Co., Ltd. to Haier. On February 29, 2024, the contractually established period for the parties to conduct the confirmatory due diligence has successfully concluded.

The company established a dedicated working group comprising senior managers from the legal, communications, finance, investor relations and management teams, together with external advisors with expertise in communications.
